    Purpose: To examine the efficacy of postoperative radiation therapy for early-stage cervical cancer with pathologic risk factors. Methods and Materials: We reviewed the charts of 83 patients who received postoperative radiation therapy at our facility from March 1980 to November 1993 for early stage cervix cancer with positive surgical margins, positive pelvic or periaortic lymph nodes, lymphovascular space invasion, deep invasion, or for disease discovered incidentally at simple hysterectomy. Twenty-eight patients received low dose rate (LDR) intracavitary radiation with or without external beam pelvic irradiation and 55 patients received external beam pelvic irradiation with high dose rate (HDR) intracavitary implants. Of these 83 patients, 66 were evaluable--20 LDR and 46 HDR patients. All patients received 45-50 Gy external beam irradiation and 20 Gy LDR equivalent intracavitary irradiation prescribed to 0.5 cm below the mucosa. Ninety percent of the LDR group and 92% of the HDR group completed treatment within < 56 days. Treatment-related toxicities were scored according to the GOG toxicity scale. Mean and median follow-up times were 101 months and 111 months (3-172 months) for the LDR group and 42 and 40 months (3-98 months) for the HDR group. Results: The 5-year disease-free survival was 89% for the LDR group and 72% for the HDR group. Local control was observed in 90% (18 out of 20) of the LDR patients and 89% (41 out of 46) of the HDR patients for an overall local control rate of 89.5%. Two of 20 LDR patients (10%) experienced recurrence (two pelvic with distant metastasis). Nine of 46 HDR patients (22%) had recurrence of disease (three pelvic, four distant metastasis, and two pelvic with distant metastasis). In the HDR group, 6 out of 16 (38%) with positive lymph nodes died of disease whereas, 27 out of 30 (90%) of the patients with negative lymph nodes remain free of disease. Three of 20 (15%) LDR patients and 4 out of 46 (9%) HDR patients experienced

    Conclusion: Tumor differentiation and LVSI were predictors of postoperative relapse for patients with pathological stage I NSCLC. Risk factors of postoperative recurrence in patients with pathological Stage I NSCLC may enable us to optimize the patient selection for postoperative adjuvant therapies to prevent possibly occult micrometastases.

    Purpose: The purpose of this study was to determine the efficacy of postoperative adjuvant radiation therapy with regard to reducing the rate of recurrence in the neck, cancer-related death, and death from any cause in patients with squamous cell carcinoma of the head and neck region metastatic to neck nodes. Methods: This was a retrospective review of patients with pathologically confirmed nodal metastases who underwent neck dissection and postoperative adjuvant radiation therapy for squamous cell carcinoma of the head and neck region. Time to recurrence in the dissected area of the neck, any recurrence in the neck, cancer-related death, and death from any cause were estimated with the Kaplan-Meier method. A matched-pair analysis was performed utilizing a cohort of patients who underwent neck dissection without postoperative radiation therapy. The patients from the two cohorts were matched according to previously reported high-risk features for cancer recurrence and death. Cox hazards models for the matched pairs were used to evaluate the relative risk of subsequent recurrence in the dissected side of the neck, any neck recurrence, cancer-related death, and overall survival. Materials: The medical records and pathologic slides of 95 consecutive patients with pathologically confirmed nodal metastases from squamous cell carcinoma of the head and neck region who underwent neck dissection and postoperative adjuvant radiation therapy between January 1974 and December 1990 were reviewed. Previously published data from 284 patients with squamous cell carcinoma of the head and neck region treated with neck dissection alone between January 1970 and December 1980 were used for a matched-pair analysis. Results: The relative risks for recurrence in the dissected side of the neck, any neck recurrence (dissected neck or delayed undissected neck metastasis), cancer-related death, and death from any cause for patients treated with operation alone relative to those treated with

    Esophageal cancer is located in the 8th position of the incidence of malignant tumors and the 6th most common cause of cancer-related mortality in the world, while China has the highest incidence and mortality of esophageal cancer. Esophageal squamous cell carcinoma (ESCC), the predominant histologic type of esophageal cancer in China, accounts for about 90%. Despite recent improvement of surgical techniques and philosophy, however, the prognosis of ESCC patients treated with surgery is still poor, and 5-year survival remains unsatisfactorily low. So far, the pathogenesis of esophageal squamous cell carcinoma is still unclear, and effective prevention is also out of the question. To find the main factors affecting the prognosis of esophageal squamous cell carcinoma, and to improve the survival of patients, are the main directions of all scholars. Postoperative pathology of esophageal squamous cell carcinoma is considered to be one of the most important predictors of prognosis. Currently, the evaluation of postoperative esophageal prognosis mainly depends on TNM staging, but some criteria of its specific content and staging remains controversial. In this paper recent domestic and foreign related researches and clinical trials reports are collected, and the postoperative pathological features affecting esophageal squamous cell carcinoma prognosis were reviewed.

    Ultrasonography (US) is a useful diagnostic modality for evaluation of the size and features of thyroid nodules. Tumor size is a key indicator of the surgical extent of thyroid cancer. We evaluated the difference in tumor sizes measured by preoperative US and postoperative pathologic examination in papillary thyroid carcinoma (PTC). We reviewed the medical records of 172 consecutive patients, who underwent thyroidectomy for PTC treatment. We compared tumor size, as measured by preoperative US, with that in postoperative specimens. And we analyzed a number of factors potentially influencing the size measurement, including cancer size, calcification and coexisting thyroiditis. The mean size of the tumor measured by preoperative US was 11.4, and 10.2 mm by postoperative pathologic examination. The mean percentage difference (US-pathology/US) of tumor sizes measured by preoperative US and postoperative pathologic examination was 9.9 ± 19.3%, which was statistically significant (p 20.0 mm) and the presence of calcification or coexisting thyroiditis on the tumor size discrepancy between the two measurements was analyzed, the mean percentage differences according to tumor size (9.1 vs. 11.2% vs. 9.8%, p = 0.842), calcification (9.2 vs. 10.2%, p = 0.756) and coexisting thyroiditis (17.6 vs. 9.5%, p = 0.223) did not show statistical significance. Tumor sizes measured in postoperative pathology were ~90% of those measured by preoperative US in PTC; this was not affected by tumor size, the presence of calcification or coexisting thyroiditis. When the surgical extent of PTC treatment according to tumor size measured by US is determined, the relative difference between tumor sizes measured by preoperative US and postoperative pathologic examination should be considered.

    The feasibility and safety of robotically assisted procedures in general surgery have been reported from various groups worldwide. Because postoperative complications may lead to longer hospital stays and higher costs overall, analysis of risk factors for postoperative surgical complications in this subset of patients is clinically relevant. The goal of this study was to identify risk factors for postoperative morbidity after robotic surgical procedures in general surgery. We performed an observational monocentric retrospective study. All consecutive robotic surgical procedures from November 2001 to December 2013 were included. One thousand consecutive general surgery patients met the inclusion criteria. The mean overall postoperative morbidity and major postoperative morbidity (Clavien >III) rates were 20.4 and 6 %, respectively. This included a conversion rate of 4.4 %, reoperation rate of 4.5 %, and mortality rate of 0.2 %. Multivariate analysis showed that ASA score >3 [OR 1.7; 95 % CI (1.2-2.4)], hematocrit value surgery [OR 1.5; 95 % CI (1-2)], advanced dissection [OR 5.8; 95 % CI (3.1-10.6)], and multiquadrant surgery [OR 2.5; 95 % CI (1.7-3.8)] remained independent risk factors for overall postoperative morbidity. It also showed that advanced dissection [OR 4.4; 95 % CI (1.9-9.6)] and multiquadrant surgery [OR 4.4; 95 % CI (2.3-8.5)] remained independent risk factors for major postoperative morbidity (Clavien >III). This study identifies independent risk factors for postoperative overall and major morbidity in robotic general surgery. Because these factors independently impacted postoperative complications, we believe they could be taken into account in future studies comparing conventional versus robot-assisted laparoscopic procedures in general surgery.

The database was queried for data related to the surgical procedure, anesthetic care, perioperative adverse events, and birth/death/operation dates. The 48 h and 30 d cumulative incidence of postoperative mortality was calculated and data were analyzed using Chi-square or Fisher’s exact test and generalized estimating equations.Results: The 48 h and 30 d incidence of postoperative mortality was 0.57% and 2.1%, respectively. Higher American Society of Anesthesiologists physical status scores, extremes of age, emergencies, perioperative adverse events and postoperative Intensive Care Unit admission were identified as risk factors. The use of monitored anesthesia care or general anesthesia versus regional or combined anesthesia was a risk factor for 30 d postoperative mortality only. Time under anesthesia care, perioperative hypothermia, trauma, deliberate hypotension and invasive monitoring via arterial, pulmonary artery or cardiovascular catheters were not identified as risk factors.Conclusions: Our findings can be used to track postoperative mortality rates and to test preventative interventions at our institution and elsewhere.Keywords: postoperative mortality, risk factors, operations, anesthesia, inpatient surgery

    Previous studies have shown that elevated depressive symptoms are associated with increased risk of postoperative delirium. However, to our knowledge no previous studies have examined whether different components of depression are differentially predictive of postoperative delirium. One thousand twenty patients were screened for postoperative delirium using the Confusion Assessment Method and through retrospective chart review. Patients underwent cognitive, psychosocial, and medical assessments preoperatively. Depression was assessed using the Geriatric Depression Scale-Short Form. Thirty-eight patients developed delirium (3.7%). Using a factor structure previously validated among geriatric medical patients, the authors examined three components of depression as predictors of postoperative delirium: negative affect, cognitive distress, and behavioral inactivity. In multivariate analyses controlling for age, education, comorbidities, and cognitive function, the authors found that greater behavioral inactivity was associated with increased risk of delirium (OR: 1.95 [1.11, 3.42]), whereas negative affect (OR: 0.65 [0.31, 1.36]) and cognitive distress (OR: 0.95 [0.63, 1.43]) were not. Different components of depression are differentially predictive of postoperative delirium among adults undergoing noncardiac surgery. Copyright © 2016 American Association for Geriatric Psychiatry.

    This descriptive, correlational study was conducted to describe constipation risk assessment and the affecting factors of constipation risk of patients who have undergone major orthopedic surgery. Data were collected using a patient information form and the Constipation Risk Assessment Scale (CRAS) on the second postoperative day. Data were analyzed using the SPSS version 11.5 for Windows. The mean age of the 83 patients studied was 53.75 ± 21.29 years. Subjects were hospitalized in the orthopedic wards for 14.39 ± 15.17 days, and their current bowel habit was 2.18 ± 1.80 stools per week. Of the sample, 63.9% were female, 69.9% of the patients had a history of previous surgery, 45.8% had hip/knee arthroplasty surgery, and 55.4% had bowel problems during the hospitalization period. Patients had a medium risk for constipation according to the CRAS subscale (gender, mobility, and pharmacological agents). Total CRAS score was 12.73 ± 4.75 (medium risk) on the second postoperative day. In addition, age, marital status, educational level, having a history of surgery, and bowel elimination problems did have a significant effect on constipation risk. On the basis of the findings from this study, nurses must learn the postoperative constipation risk of orthopedic patients to implement safe and effective interventions.

    Selection of patients for hepatectomy for hepatocellular carcinoma conventionally has been based upon Child-Pugh grading. However, postoperative liver failure after hepatectomy is a major cause of hospital mortality. A new predictor of postoperative liver failure is required. The objective of this study was to identify risk factors for postoperative liver failure after hepatectomy. Perioperative risk factors for liver failure after hepatectomy were analyzed in 112 patients with hepatocellular carcinoma Eight of these patients died of liver failure. Stepwise multivariate logistic regression was performed to investigate significant independent factors among 17 variables, including the serum alkaline phosphatase ratio (ALPR) on the first day after hepatectomy. ALPR was calculated as the postoperative ALP level divided by the ALP level before surgery. Significant risk factors of postoperative liver failure were ALPR on postoperative day 1 (ALPR1), sex, operative blood loss, and operative procedure. As an indicator of liver failure, the diagnostic accuracy of the ALPR1 was 93.7% when the ALPR was less than 0.4 on the first postoperative day. The ALPR and the serum total bilirubin concentration after hepatectomy were uncorrelated. ALPR1 is a useful predictor of liver failure after hepatectomy.

    In France, consumption of gambling games increased by 148% between 1960 and 2005. In 2004, gamblers lost approximately 0.9% of household income, compared to 0.4% in 1960. This represents approximately 134 Euros per year and per head. In spite of this important increase, the level remains lower than the European average (1%). However, gambling practices may continue to escalate in France in the next few years, particularly with the recent announce of the legalisation of online games and sports betting. With the spread of legalised gambling, pathological gambling rates may increase in France in the next years, in response to more widely available and more attractive gambling opportunities. In this context, there is a need for better understanding of the risk factors that are implicated in the development and maintenance of pathological gambling. This paper briefly describes the major risk factors for pathological gambling by examining the recent published literature available during the first quarter of 2008. This documentary basis was collected by Inserm for the collective expert report procedure on Gambling (contexts and addictions). Seventy-two articles focusing on risk factors for pathological gambling were considered in this review. Only 47 of them were taken into account for analysis. The selection of these 47 publications was based on the guide on literature analysis established by the French National Agency for Accreditation and Assessment in Health (ANAES, 2000). Some publications from more recent literature have also been added, mostly about Internet gambling. We identify three major types of risk factors implicated in gambling problems: some of them are related to the subject (individual factors), others are related to the object of the addiction, here the gambling activity by itself (structural factors), and the last are related to environment (contextual or situational factors). Thus, the development and maintenance of pathological gambling seems to be

    Purpose: To evaluate the efficacy of postoperative adjuvant radiotherapy (RT) for positive resection margin and/or pathologic T3 (pT3) adenocarcinoma of the prostate with undetectable postoperative prostate-specific antigen (PSA) levels. Methods and materials: We retrospectively analyzed 125 patients with a positive resection margin and/or pT3 adenocarcinoma of the prostate who had undetectable postoperative serum PSA levels after radical prostatectomy. Seventy-three patients received postoperative adjuvant RT and 52 did not. Follow-up ranged from 1.5 to 12.0 years (median 4.2 for the irradiated group and 4.9 for the nonirradiated group). PSA outcome was available for all patients. Freedom from failure was defined as the maintenance of a serum PSA level of ≤0.2 ng/mL, as well as the absence of clinical local recurrence and distant metastasis. Results: No difference was found in the 5-year actuarial overall survival between the irradiated and nonirradiated group (94% vs. 95%). However, patients receiving adjuvant RT had a statistically superior 5-year actuarial relapse-free rate, including freedom from PSA failure, compared with those treated with surgery alone (88% vs. 65%, p=0.0013). In the irradiated group, 8 patients had relapse with PSA failure alone. None had local or distant recurrence. In the nonirradiated group, 15, 1, and 2 had PSA failure, local recurrence, and distant metastasis, respectively. On Cox regression analysis, pre-radical prostatectomy PSA level and adjuvant RT were statistically significant predictive factors for relapse, and Gleason score, extracapsular invasion, and resection margin status were not. There was a suggestion that seminal vesicle invasion was associated with an increased risk of relapse. The morbidity of postoperative adjuvant RT was acceptable, with only 2 patients developing Radiation Therapy Oncology Group Grade 3 genitourinary complications. Adjuvant RT had a minimal adverse effect on urinary continence and did not cause

    To evaluate treatment outcome of patients with high risk locally advanced gastric cancer after postoperative chemoradiotherapy. Between May 2003 and May 2012, thirteen patients who underwent postoperative chemoradiotherapy for gastric cancer with resection margin involvement or adjacent structure invasion were retrospectively analyzed. Concurrent chemotherapy was administered in 10 patients. Median dose of radiation was 50.4 Gy (range, 45 to 55.8 Gy). The median follow-up duration for surviving patients was 48 months (range, 5 to 108 months). The 5-year overall survival rate was 42% and the 5-year disease-free survival rate was 28%. Major pattern of failure was peritoneal seeding with 46%. Loco-regional recurrence was reported in only one patient. Grade 2 or higher gastrointestinal toxicity occurred in 54% of the patients. However, there was only one patient with higher than grade 3 toxicity. Despite reported suggested role of adjuvant radiotherapy with combination chemotherapy in gastric cancer, only very small portion of the patients underwent the treatment. Results from this study show that postoperative chemoradiotherapy provided excellent locoregional control with acceptable and manageable treatment related toxicity in patients with high risk locally advanced gastric cancer. Thus, postoperative chemoradiotherapy may improve treatment result in terms of locoregional control in these high risk patients. However, as these findings are based on small series, validation with larger cohort is suggested.

    Postoperative cerebrospinal fluid (CSF) leak is a persistent, albeit much less prominent, complication following endonasal endoscopic surgery. The pathology with highest risk is suprasellar meningiomas. A postoperative lumbar drain (LD) is used to decrease the risk of CSF leak but is not universally accepted. To compare the rates of postoperative CSF leak between patients with and without LD who underwent endonasal endoscopic surgical resection of suprasellar meningiomas. A consecutive series of newly diagnosed suprasellar meningiomas was drawn from a prospectively acquired database of endonasal endoscopic surgeries at our institution. An intraoperative, preresection LD was placed and left open at 5 cc/h for ∼48 h. In a subset of patients, the LD could not be placed. Rates of postoperative CSF leak were compared between patients with and without an LD. Twenty-five patients underwent endonasal endoscopic surgical resection of suprasellar meningiomas. An LD could not be placed in 2 patients. There were 2 postoperative CSF leaks (8%), both of which occurred in the patients who did not have an LD (P = .0033). The average body mass index (BMI) of the patients in whom the LD could not be placed was 39.1 kg/m2, compared with 27.6 kg/m2 for those in whom the LD could be placed (P = .009). In the subgroup of obese patients (BMI > 30 kg/m2), LD placement was protective against postoperative CSF leak (P = .022). The inability to place an LD in patients with obesity is a risk factor for postoperative CSF leak. An LD may be useful to prevent postoperative CSF leak, particularly in patients with elevated BMI.

    Postoperative intracranial infectious complications are one of the most topical problems of neurosurgical intensive care due to theirs significant capability to impair outcomes of the main disease. To define the risk factors of postoperative meningitis in patients with chiasm-sellar tumors. 1. to define the effect of somatic and intracranial risk factors on occurrence of postoperative meningitis in patients after transsphenoidal and transcranial approaches to the tumor. 2. To define the effect of postoperative meningitis on outcomes of treatment in patients after transsphenoidal and transcranial approaches to the tumor. Somatic and intracranial risk factors of occurrence of postoperative meningitis (pneumonia, urinary tract infection, sepsis, intra-abdominal hypertension, the presence of external ventricular and lumbar drainage, monitoring of intracranial pressure, cerebrospinal fluid, and reoperation) were fixed every day. The study was conducted in the ICU of the Burdenko from October, 2010 to July, 2012. The 34 patients (19 males, 15 females) were included in the study (average age 47.5 years). The patients were divided into two groups; 17 patients each group. The group-1 included patients after transcranial approach to the tumor and the group-2 included patients after transsphenoidal approach. In the group-1 a meningitis occurred in 3 patients (17.6% +/- 9.2%, DI [-0.4 - 35.6]). In the group-2 a meningitis occurred in 7 patients (41.2% +/- 11.9) DI 95% [17.8 - 64.4]. Accumulation of cerebrospinal fluid under the skin flap authentically increased a risk of a meningitis occurrence in patients after transcranial approach to the tumor (p = 0.031). There was no defined statistical significance of other risk factors. But there was defined a trend of the increasing of meningitis occurrence in patients after transsphenoidal approach in case of lumbar drainage or reoperation. Duration of mechanical ventilation and ICU stay in patients with meningitis was authentically

    Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI). Selecting the appropriate radiological modality is key to making the correct diagnosis. Therefore, knowledge of the initial and current symptoms is just as important as familiarity with the most frequently performed operations in the ankle. This article aims to give its reader a summary of the most important and frequently performed operation techniques of the ankle and discusses the expected appearance and possible complications in postoperative imaging. (orig.) [German] Die postoperative radiologische Bildgebung des Sprunggelenks kann auch fuer den erfahrenen Radiologen eine besondere Herausforderung darstellen. Die komplex aufgebaute Anatomie des Sprunggelenks, mit seinen multiplen Gelenkflaechen, Sehnen, Baendern und neurovaskulaeren Strukturen auf engstem Raum, kann durch Operationen signifikant veraendert und insbesondere in der Magnetresonanztomographie (MRT) verfaelscht dargestellt werden. Fuer eine fundierte Befundung und Beurteilung der Operationsergebnisse ist die Kenntnis der praeoperativen Diagnose, Zeitpunkt und Technik der durchgefuehrten Operation(en) sowie der aktuellen klinischen Symptomatik von grosser Bedeutung. Dieser Artikel konzentriert sich auf zu erwartende radiologische Veraenderungen und gibt Tipps zur Befundung der postoperativen MRT des Sprunggelenks bei einer Auswahl relevanter operativer Eingriffe.

    Full Text Available Higher levels of fibrinogen, a critical element in hemostasis, are associated with increased postoperative survival rates, especially for patients with massive operative blood loss. Fibrinogen deficiency after surgical management of intracranial tumors may result in postoperative intracranial bleeding and severely worsen patient outcomes. However, no previous studies have systematically identified factors associated with postoperative fibrinogen deficiency. In this study, we retrospectively analyzed data from patients who underwent surgical removal of intracranial tumors in Beijing Tiantan Hospital date from 1/1/2013to12/31/2013. The present study found that patients with postoperative fibrinogen deficiency experienced more operative blood loss and a higher rate of postoperative intracranial hematoma, and they were given more blood transfusions, more plasma transfusions, and were administered larger doses of hemocoagulase compared with patients without postoperative fibrinogen deficiency. Likewise, patients with postoperative fibrinogen deficiency had poorer extended Glasgow Outcome Scale (GOSe, longer hospital stays, and greater hospital expenses than patients without postoperative fibrinogen deficiency. Further, we assessed a comprehensive set of risk factors associated with postoperative fibrinogen deficiency via multiple linear regression. We found that body mass index (BMI, the occurrence of postoperative intracranial hematoma, and administration of hemocoagulasewere positively associated with preoperative-to-postoperative plasma fibrinogen consumption; presenting with a malignant tumor was negatively associated with fibrinogen consumption. Contrary to what might be expected, intraoperative blood loss, the need for blood transfusion, and the need for plasma transfusion were not associated with plasma fibrinogen consumption. Considering our findings together, we concluded that postoperative fibrinogen deficiency is closely associated with

    Transient postoperative dysphagia is not uncommon after antireflux surgery and usually runs a self-limiting course. However, a subset of patients report long-term dysphagia. The purpose of this study was to determine the risk factors for persistent postoperative dysphagia at 1 year after surgery. All patients who underwent antireflux surgery were entered into a prospectively maintained database. After obtaining institutional review board approval, the database was queried to identify patients who underwent primary antireflux surgery and were at least 1 year from surgery. Postoperative severity of dysphagia was evaluated using a standardized questionnaire (scale 0-3). Patients with scores of 2 or 3 were defined as having significant dysphagia. A total of 316 consecutive patients underwent primary antireflux surgery by a single surgeon. Of these, 219 patients had 1 year postoperative symptom data. Significant postoperative dysphagia at 1 year was reported by 19 (9.1%) patients. Thirty-eight patients (18.3%) required postoperative dilation for dysphagia. Multivariate logistic regression analysis identified preoperative dysphagia (odds ratio (OR), 4.4; 95% confidence interval (CI), 1.2-15.5; p = 0.023) and preoperative delayed esophageal transit by barium swallow (OR, 8.2; 95% CI, 1.6-42.2; p = 0.012) as risk factors for postoperative dysphagia. Female gender was a risk factor for requiring dilation during the early postoperative period (OR, 3.6; 95% CI, 1.3-10.2; p = 0.016). No correlations were found with preoperative manometry. There also was no correlation between a need for early dilation and persistent dysphagia at 1 year of follow-up (p = 0.109). Patients with preoperative dysphagia and delayed esophageal transit on preoperative contrast study were significantly more likely to report moderate to severe postoperative dysphagia 1 year after antireflux surgery. This study confirms that the manometric criteria used to define esophageal dysmotility are not reliable

    Wildfire risk in temperate forests has become a nearly intractable problem that can be characterized as a socioecological “pathology”: that is, a set of complex and problematic interactions among social and ecological systems across multiple spatial and temporal scales. Assessments of wildfire risk could benefit from recognizing and accounting for these interactions in terms of socioecological systems, also known as coupled natural and human systems (CNHS). We characterize the primary social and ecological dimensions of the wildfire risk pathology, paying particular attention to the governance system around wildfire risk, and suggest strategies to mitigate the pathology through innovative planning approaches, analytical tools, and policies. We caution that even with a clear understanding of the problem and possible solutions, the system by which human actors govern fire-prone forests may evolve incrementally in imperfect ways and can be expected to resist change even as we learn better ways to manage CNHS.

    Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI). Selecting the appropriate radiological modality is key to making the correct diagnosis. Therefore, knowledge of the initial and current symptoms is just as important as familiarity with the most frequently performed operations in the ankle. This article aims to give its reader a summary of the most important and frequently performed operation techniques of the ankle and discusses the expected appearance and possible complications in postoperative imaging.

    Full Text Available Aim: Many etiological factors play a role in the occurrence of postoperative empyema. We aimed to define the effects of these factors on the development of empyema. Material and Method: Two hundred and eighty-eight cases from our clinic who underwent tube thoracostomy and/or were operated due to any cause out of the primary empyema  between August 2009 and May 2010 were prospectively studied in terms of empyema development. Data comprised gender, age, chemoradiotherapy, surgical procedure, intraoperative thoracic lavage with povidone-iodine, emergency surgery status, sharing the same room with other cases with empyema, primary disease, additional comorbidity, operation duration, drain number, complication, number of patients in the room, and drain discontinuation and hospitalization duration. Blood leukocyte-neutrophil count was ordered in all cases at 3-day intervals, and fluid culture specimens were simultaneously collected from cases with drains. Drainage fluid culture specimens were evaluated with “Automated Identification and Antibiotic Susceptibility Testing” using standard procedures. Empyema cases who developed clinical manifestation and/or with bacterial growth in culture specimens were studied in terms of risk factors. The findings were analyzed using SPSS (version 16. Results: The results showed that gender, age, chemoradiotherapy, surgical procedure, intraoperative thoracic lavage with povidone-iodine, emergency surgery status, and sharing a same room with other empyema cases were not significantly correlated with the risk of empyema development. Contribution of the primary disease (p<0.05, additional comorbidity (p<0.05, operation duration (p<0.05, drain number (p<0.05, complication (p<0.05, number of people in the room (p<0.05, drain discontinuation time (p<0.05 and hospitalization duration (p<0.05 were found to be significant in the development of postoperative empyema. Discussion: Postoperative development of empyema is one

    When treating cerebral metastases all involved multidisciplinary oncological specialists have to cooperate closely to provide the best care for these patients. For the resection of brain metastasis several studies reported a considerable risk of new postoperative paresis. Pre- and perioperative chemotherapy (Ctx) or radiotherapy (Rtx) alter vasculature and adjacent fiber tracts on the one hand, and many patients already present with paresis prior to surgery on the other hand. As such factors were repeatedly considered risk factors for perioperative complications, we designed this study to also identify risk factors for brain metastases resection. Between 2006 and 2011, we resected 206 brain metastases consecutively, 56 in eloquent motor areas and 150 in non-eloquent ones. We evaluated the influences of preoperative paresis, previous Rtx or Ctx as well as recursive partitioning analysis (RPA) class on postoperative outcome. In general, 8.7% of all patients postoperatively developed a new permanent paresis. In contrast to preoperative Ctx, previous Rtx as a single or combined treatment strategy was a significant risk factor for postoperative motor weakness. This risk was even increased in perirolandic and rolandic lesions. Our data show significantly increased risk of new deficits for patients assigned to RPA class 3. Even in non-eloquently located brain metastases the risk of new postoperative paresis has not to be underestimated. Despite the microsurgical approach, our cohort shows a high rate of unexpected residual tumors in postoperative MRI, which supports recent data on brain metastases’ infiltrative nature but might also be the result of our strict study protocol. Surgical resection is a safe treatment of brain metastases. However, preoperative Rtx and RPA score 3 have to be taken into account when surgical resection is considered

    Splenectomy is associated with a life-long risk for overwhelming infections. The risk for early post-operative infectious complications following traumatic and elective splenectomy is, however, understudied. This investigation aimed to determine if splenectomy increases the risk for post-operative infections. This was a retrospective review of prospectively collected data on patients admitted to the surgical intensive care unit (SICU) between 1/2011 and 7/2013 investigating the risk for infectious complications in patients undergoing a splenectomy compared with those undergoing any other abdominal surgery. During the 30-month study period, a total of 1884 patients were admitted to the SICU. Of those, 33 (2%) had a splenectomy and 493 (26%) had an abdominal surgery. The two groups were well balanced for age, APACHE IV score >20, and past medical history, including diabetes mellitus, cardiac history, renal failure or immunosuppression. Patients undergoing splenectomy were more likely to have sustained a traumatic injury (30% vs. 7%, p splenectomy was associated with increased risk for infectious complications (49% vs. 29%, Adjusted Odds Ratio (AOR) [95% CI]: 2.7 [1.3, 5.6], p = 0.01), including intra-abdominal abscess (9% vs. 3%, AOR [95% CI]: 4.3 [1.1, 16.2], p = 0.03). On a subgroup analysis, there were no differences between traumatic and elective splenectomy with regards to overall infectious complications (50% vs. 46%, p = 0.84), although, abdominal abscess developed only in those who had an elective splenectomy (0% vs. 12%, p = 0.55). Splenectomy increases the risk for post-operative infectious complications. Further studies identifying strategies to decrease the associated morbidity are necessary.

    To determine whether sleep disruption at home or in hospital is an independent risk factor for postoperative delirium in older adults undergoing elective surgery. Prospective cohort study. German teaching hospital. Individuals aged 65 and older undergoing elective arthroplasty (N = 101). Preoperative questionnaires were used to assess sleep disruption at home (Pittsburgh Sleep Quality Index). Actigraphy was used to objectively measure sleep disruption in the hospital before and after surgery. Delirium was assessed daily after surgery using the Confusion Assessment Method and, if there was uncertainty, validated according to International Classification of Diseases, Tenth Revision (ICD-10), criteria. Twenty-seven participants developed postoperative delirium. Those with sleep disruption at home were 3.26 times as likely to develop postoperative delirium as those without (95% confidence interval (CI) = 1.34-7.92, P = .009). Participants with sleep disruption in hospital were 1.21 times as likely to develop postoperative delirium as those without (95% CI = 1.03-1.41, P = .02). When adjusting for other variables, risk remained significant for sleep disruption at home (risk ratio (RR) = 3.90, 95% CI = 2.14-7.11, P delirium than those without. Sleep disruption in the hospital may further heighten this risk. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Factors associated with risk for adverse outcome are important considerations in the preoperative assessment of patients for bariatric surgery. As yet, prediction models based on preoperative risk factors have not been able to predict adverse outcome sufficiently. This study aimed to identify preoperative risk factors and to construct a risk prediction model based on these. Patients who underwent a bariatric surgical procedure in Sweden between 2010 and 2014 were identified from the Scandinavian Obesity Surgery Registry (SOReg). Associations between preoperative potential risk factors and severe postoperative complications were analysed using a logistic regression model. A multivariate model for risk prediction was created and validated in the SOReg for patients who underwent bariatric surgery in Sweden, 2015. Revision surgery (standardized OR 1.19, 95% confidence interval (CI) 1.14-0.24, p prediction model. Despite high specificity, the sensitivity of the model was low. Revision surgery, high age, low BMI, large waist circumference, and dyspepsia/GERD were associated with an increased risk for severe postoperative complication. The prediction model based on these factors, however, had a sensitivity that was too low to predict risk in the individual patient case.

    To compare the efficacy of ondansetron and granisetron in the prevention of postoperative nausea and vomiting (PONV) in high-risk patients. Totally 200 patients with three key risk factors for PONV (female, non-smoking and postoperative opioid use) were equally randomized into ondansetron group and granisetron group. Ondansetron (4 mg) or granisetron (3 mg) was intravenously administered upon the completion of surgery. The episodes of nausea and vomiting were observed for 24 hours after surgery. A significantly greater proportion of patients in granisetron group achieved a complete response (i.e., no PONV or rescue medication) during the first 24 hours postoperatively versus those in ondansetron group (62.6% vs. 46.9%, respectively; P=0.048). There were no significant differences in terms of postoperative nausea incidences (42.9% vs. 34.3%, respectively), postoperative vomiting incidences (25.5% vs. 20.2%, respectively) and postoperative rescue anti-emetics incidences (19.4% vs. 15.2%, respectively) (P>0.05). Granisetron is more effective than ondansetron in preventing PONV in high-risk patients during the first 24 hours postoperatively.

    Purpose: To analyze the efficacy, toxicity, and pattern of relapse after adjuvant cisplatin-based chemotherapy followed by three-dimensional irradiation and concomitant LV5FU2 chemotherapy (high-dose leucovorin and 5-fluorouracil bolus plus continuous infusion) in the treatment of completely resected high-risk gastric cancer. Methods and Materials: This was a retrospective analysis of 52 patients with high-risk gastric cancer initially treated by total/partial gastrectomy and lymphadenectomy between January 2002 and June 2007. Median age was 54 years (range, 36–75 years). Postoperative treatment consisted of 5-fluorouracil and cisplatin chemotherapy. Adjuvant chemotherapy was followed by three-dimensional conformal radiotherapy in the tumor bed and regional lymph nodes at 4500 cGy/25 fractions in association with concomitant chemotherapy. Concomitant chemotherapy consisted of a 2-h infusion of leucovorin (200 mg/m²) followed by a bolus of 5-fluorouracil (400 mg/m²) and then a 44-h continuous infusion of 5-fluorouracil (2400–3600 mg/m²) given every 14 days, for three cycles (LV5FU2 protocol). Results: Five-year overall and disease-free survival were 50% and 48%, respectively. Distant metastases and peritoneal spread were the most frequent sites of relapse (37% each). After multivariate analysis, only pathologic nodal status was significantly associated with disease-free and overall survival. Acute toxicities were essentially gastrointestinal and hematologic. One myocardial infarction and one pulmonary embolism were also reported. Eighteen patients had a radiotherapy program interruption because of acute toxicity. All patients but 2 have completed radiotherapy. Conclusion: Postoperative cisplatin-based chemotherapy followed by conformal radiotherapy in association with concurrent 5-fluorouracil seemed to be feasible and resulted in successful locoregional control.

  11. Ultrasound assessment of selected peripheral nerve pathologies. Part III: Injuries and postoperative evaluation

    Full Text Available The previous articles of the series devoted to ultrasound diagnostics of peripheral nerves concerned the most common nerve pathologies, i.e. entrapment neuropathies. The aim of the last part of the series is to present ultrasound possibilities in the postoperative control of the peripheral nerves as well as in the diagnostics of the second most common neuropathies of peripheral nerves, i.e. posttraumatic lesions. Early diagnostics of posttraumatic changes is of fundamental importance for the course of treatment and its long-term effects. It aids surgeons in making treatment decisions (whether surgical or conservative. When surgical treatment is necessary, the surgeon, based on US findings, is able to plan a given type of operative method. In certain cases, may even abandon the corrective or reconstructive surgery of the nerve trunk (when there are extensive defects of the nerve trunks and instead, proceed with muscle transfers. Medical literature proposes a range of divisions of the kinds of peripheral nerve injuries depending on, among others, the mechanism or degree of damage. However, the most important issue in the surgeon-diagnostician communication is a detailed description of stumps of the nerve trunks, their distance and location. In the postoperative period, ultrasound is used for monitoring the operative or conservative treatment effects including the determination of the causes of a persistent or recurrent neuropathy. It facilitates decision-making concerning a repeated surgical procedure or assuming a wait-and-see attitude. It is a difficult task for a diagnostician and it requires experience, close cooperation with a clinician and knowledge concerning surgical techniques. Apart from a static assessment, a dynamic assessment of possible adhesions constitutes a crucial element of postoperative examination. This feature distinguishes ultrasound scanning from other methods used in the diagnostics of peripheral neuropathies.

    Purpose: To determine if perineural invasion (PNI) should be included in addition to prostate-specific antigen (PSA), biopsy Gleason score, and clinical T-stage for risk-stratification of patients with localized prostate cancer. Methods and Materials: We analyzed prostatectomy findings for 1550 patients, from a prospectively collected institutional database, to determine whether PNI was a significant predictor for upgrading of Gleason score or pathologic T3 disease after patients were stratified into low-, intermediate-, and high-risk groups (on the basis of PSA, biopsy Gleason score, and clinical T-stage). Results: For the overall population, PNI was associated with a significantly increased frequency of upgrading and of pathologic T3 disease. After stratification, PNI was still associated with significantly increased odds of pathologic T3 disease within each risk group. In particular, for low-risk patients, there was a markedly increased risk of extraprostatic extension (23% vs. 7%), comparable to that of intermediate-risk patients. Among high-risk patients, PNI was associated with an increased risk of seminal vesicle invasion and lymph node involvement. Furthermore, over 80% of high-risk patients with PNI were noted to have an indication for postoperative radiation. Conclusions: Perineural invasion may be useful for risk-stratification of prostate cancer. Our data suggest that low-risk patients with PNI on biopsy may benefit from treatment typically reserved for those with intermediate-risk disease. In addition, men with high-risk disease and PNI, who are contemplating surgery, should be informed of the high likelihood of having an indication for postoperative radiation therapy

    Diabetes insipidus (DI) after endoscopic transsphenoidal surgery (ETSS) can lead to increased morbidity, longer hospital stays, and increased medication requirements. Predicting which patients are at high risk for developing DI can help direct services to ensure adequate care and follow-up. The objective of this study was to review our institution's experience with ETSS and determine which clinical/laboratory variables are associated with DI in this patient population. The authors wanted to see if there was an easily determined single value that would help predict which patients develop DI. This represents the largest North American series of this type. We retrospectively reviewed the charts of patients who had undergone ETSS for resection of sellar and parasellar pathology between 2006 and 2011. We examined patient and tumor characteristics and their relationship to postoperative DI. Out of 172 endoscopic transsphenoidal surgeries, there were 15 cases of transient DI (8.7%) and 14 cases of permanent DI (8.1%). Statistically significant predictors of postoperative DI (p 1-deamino-8-D-arginine vasopressin. An increase in serum sodium of ≥2.5 mmol/L is a positive marker of development of DI with 80% specificity, and a postoperative serum sodium of ≥145 mmol/L is a positive indicator with 98% specificity. Identifying perioperative risk factors and objective indicators of DI after ETSS will help physicians care for patients postoperatively. In this large series, we demonstrated that there were multiple perioperative risk factors for the development of DI. These findings, which are consistent with other reports from microscopic surgical series, will help identify patients at risk for diabetes insipidus, aid in planning treatment algorithms, and increase vigilance in high risk patients.

    The main purpose of this thesis was to examine whether the Danish National Patient Registry (NPR) could be used to monitor and assess the quality of cataract surgery in Denmark by studying the risks of two serious postoperative complications following cataract surgery - retinal detachment (RD......) and postoperative endophthalmitis (PE). The thesis consists of four retrospective studies. In the first study (paper I), we used data from the NPR in the calendar period 2000-2010 to investigate the risk of pseudophakic retinal detachment (PRD) using the fellow non-operated eyes of the patients as reference....... The study showed that over a 10-year study period, the risk of PRD was increased by a factor of 4.2 irrespective of sex and age. The risk of PRD was highest in the first part of the postoperative period and then gradually decreased but remained statistically significantly higher than the risk of RD in non...

    Hepatobiliary and pancreatic (HPB) operations have a high incidence of post-operative nosocomial infections. The aim of the present study was to determine whether hospitalization up to 1 year before HPB surgery is associated with an increased risk of post-operative infection, surgical-site infection (SSI) and infection resistant to surgical chemoprophylaxis. A retrospective cohort study of patients undergoing HPB surgeries between January 2008 and June 2013 was conducted. A multivariable logistic regression model was used for controlling for potential confounders to determine the association between pre-operative admission and post-operative infection. Of the 1384 patients who met eligibility criteria, 127 (9.18%) experienced a post-operative infection. Pre-operative hospitalization was independently associated with an increased risk of a post-operative infection [adjusted odds ratio (aOR): 1.61, 95% confidence interval [CI]: 1.06-2.46] and SSI (aOR: 1.79, 95% CI: 1.07-2.97). Pre-operative hospitalization was also associated with an increased risk of post-operative infections resistant to standard pre-operative antibiotics (OR: 2.64, 95% CI: 1.06-6.59) and an increased risk of resistant SSIs (OR: 3.99, 95% CI: 1.25-12.73). Pre-operative hospitalization is associated with an increased incidence of post-operative infections, often with organisms that are resistant to surgical chemoprophylaxis. Patients hospitalized up to 1 year before HPB surgery may benefit from extended spectrum chemoprophylaxis. © 2015 International Hepato-Pancreato-Biliary Association.

    The number of geriatric patients with esophageal cancer is increasing in step with the aging of the population. Geriatric patients have a higher risk of postoperative complications, including delirium that can cause a fall or impact survival. Therefore, it is very important that we evaluate risks of postoperative complications before surgery. The aim of this study was to predict postoperative delirium in elderly patients. We retrospectively reviewed the medical records of 91 patients aged 75 years and over who underwent esophagectomy between January 2006 and December 2014. We investigated the association between postoperative delirium and clinicopathological factors, including comprehensive geriatric assessment (CGA). Postoperative delirium developed in 24 (26 %) patients. Postoperative delirium was significantly associated with low mini-mental state examination (MMSE) and high Geriatric Depression Scale 15 (GDS15), which are components of CGA, and psychiatric disorder (P patients undergoing esophagectomy for esophageal cancer. Intervention by a multidisciplinary team using CGA might help prevent postoperative delirium.

    2018-06-01

    Full Text Available Background: The author (Dr. Shiao modified traditional stapes surgery (TSS specifically for patients with otosclerosis. The proposed technique, referred to as minimally traumatic stapes surgery (MTSS, reduces the risk of subjective discomfort (i.e. vertigo and tinnitus following surgery. This paper compares the effectiveness of MTSS with that of TSS. Methods: The medical records of patients with otosclerosis after stapes surgery (TSS or MTSS were analyzed. Outcome variables included post-operative vertigo, tinnitus, and hearing success. Multivariate logistic regression analysis was used to determine the correlation between surgical technique and outcome variables. Results: TSS was performed in 23 otosclerosis ears and MTSS was performed in 33 otosclerosis ears. The risk of post-operative vertigo was significantly lower among patients that underwent MTSS (27% than among those that underwent TSS (83%, p < 0.001. No differences in the incidence of tinnitus were observed between the two groups. Post-operative audiometric outcomes were also equivalent between the two groups. However, multivariate logistic regression analysis revealed a correlation between post-operative vertigo and surgical technique (p < 0.001. Conclusion: MTSS involves a lower risk of vertigo than does TSS. MTSS helps to prevent damage to the footplate, thereby reducing the risk of footplate floating. Therefore, MTSS provides a means to overcome some of the limitations associated with the narrow surgical field in Asian patients.

    Surgical quality improvement tools such as NSQIP are limited in their ability to prospectively affect individual patient care by the retrospective audit and feedback nature of their design. We hypothesized that statistical models using patient preoperative characteristics could prospectively provide risk estimates of postoperative adverse events comparable to risk estimates provided by experienced surgeons, and could be useful for stratifying preoperative assessment of patient risk. This was a prospective observational cohort. Using previously developed models for 30-day postoperative mortality, overall morbidity, cardiac, thromboembolic, pulmonary, renal, and surgical site infection (SSI) complications, model and surgeon estimates of risk were compared with each other and with actual 30-day outcomes. The study cohort included 1,791 general surgery patients operated on between June 2010 and January 2012. Observed outcomes were mortality (0.2%), overall morbidity (8.2%), and pulmonary (1.3%), cardiac (0.3%), thromboembolism (0.2%), renal (0.4%), and SSI (3.8%) complications. Model and surgeon risk estimates showed significant correlation (p risk for overall morbidity to be low, the model-predicted risk and observed morbidity rates were 2.8% and 4.1%, respectively, compared with 10% and 18% in perceived high risk patients. Patients in the highest quartile of model-predicted risk accounted for 75% of observed mortality and 52% of morbidity. Across a broad range of general surgical operations, we confirmed that the model risk estimates are in fairly good agreement with risk estimates of experienced surgeons. Using these models prospectively can identify patients at high risk for morbidity and mortality, who could then be targeted for intervention to reduce postoperative complications.

    Object Postoperative CSF leakage can be a serious complication after a transsphenoidal surgical approach. An elevated body mass index (BMI) is a significant risk factor for spontaneous CSF leaks. However, there is no evidence correlating BMI with postoperative CSF leak after transsphenoidal surgery. The authors hypothesized that patients with elevated BMI would have a higher incidence of CSF leakage complications following transsphenoidal surgery. Methods The authors conducted a retrospective review of 121 patients who, between August 2005 and March 2010, underwent endoscopic endonasal transsphenoidal surgeries for resection of primarily sellar masses. Patients requiring extended transsphenoidal approaches were excluded. A multivariate statistical analysis was performed to investigate the association of BMI and other risk factors with postoperative CSF leakage. Results In 92 patients, 96 endonasal endoscopic transsphenoidal surgeries were performed that met inclusion criteria. Thirteen postoperative leaks occurred and required subsequent treatment, including lumbar drainage and/or reoperation. The average BMI of patients with a postoperative CSF leak was significantly greater than that in patients with no postoperative CSF leak (39.2 vs 32.9 kg/m2, p = 0.006). Multivariate analyses indicate that for every 5-kg/m2 increase in BMI, patients undergoing a transsphenoidal approach for a primarily sellar mass have 1.61 times the odds (95% CI 1.10–2.29, p = 0.016, by multivariate logistic regression) of having a postoperative CSF leak. Conclusions Elevated BMI is an independent predictor of postoperative CSF leak after an endonasal endoscopic transsphenoidal approach. The authors recommend that patients with BMI greater than 30 kg/m2 have meticulous sellar reconstruction at surgery and close monitoring postoperatively. PMID:22443502

    Postoperative nausea and vomiting are a common complication after surgery. The objective of the study was to identify risk factors, and to determine the incidence of postoperative nausea and vomiting in a cohort of patients in a tertiary university hospital. Prospective cohort study was conducted in a Post Anesthetic Care Unit during a period of 3 weeks. One hundred and fifty-seven adult patients subjected to scheduled non-cardiac and non-intracranial surgery were eligible for the study. Patient perioperative characteristics data were analyzed. The postoperative nausea and vomiting intensity scale and nausea visual analog scale were applied to measure postoperative nausea and vomiting at 6h and 24h after surgery. Descriptive analysis was performed and the Mann-Whitney U, Fisher's exact, or Chi-square tests were applied. A univariate and multivariate logistic binary regressions with calculation of odds ratio (OR) and its 95% confidence interval (95% CI) were performed. Thirty-nine (25%) patients and 54 (34%) patients had postoperative nausea and vomiting at 6h and 24h, respectively. Of the patients who experienced postoperative nausea and vomiting, 6 (15%) had clinically significant postoperative nausea and vomiting (postoperative nausea and vomiting intensity scale>50) at 6h and 9 (23%) at 24h. The majority of patients classified nausea as mild at 6h (57%) and 24h (56%). At 6h, 3 (10%) patients classified nausea as severe, and at 24h 5 (9%) patients reported the same. The median and interquartile ranges for nausea visual analog scale were 40 (20-60) at 6h and 50 (20-60) at 24h. Six patients (14%) at 6h, and 7 (18%) at 24h had a nausea visual analog scale score>75. Patients with postoperative nausea and vomiting intensity scale>50 had higher scores in the nausea visual analog scale at 6h (75 versus 30, P2 (OR 3.2, 95% CI 1.6-6.4, P=.001), previous history of postoperative nausea and vomiting (OR 2.9 95% CI 1.3-6.5, P=.009) and female patients (OR 2.7, 95% CI 1

    Hypocalcaemia is the most common complication following thyroidectomy. This study aimed to establish the factors associated with increased risk of hypocalcaemia on day 1 following thyroidectomy. All patients who underwent thyroidectomy under a single consultant during a 5-year period were included. A multivariate analysis was undertaken to ascertain which variables had the most effect on the risk of hypocalcaemia. A prognosis table was constructed to allow risk to be predicted for individual patients based on these factors. Included in the analysis were 210 procedures and 194 patients. Eighty-two percent of patients had no calcium derangement postoperatively. Fourteen point nine percent were categorised as early hypocalcaemia, 1 % had protracted hypocalcaemia and 2.1 % had permanent hypocalcaemia. For hemi-thyroidectomies 2.8 % had postoperative hypocalcaemia and 0.9 % had permanent hypocalcaemia. The multivariate analysis revealed total thyroidectomy (risk ratio 26.5, p < 0.0001), diabetes (risk ratio 4.8, p = 0.07) and thyrotoxicosis (risk ratio 3.1, p = 0.04) as statistically significant variables for early postoperative hypocalcaemia. Gender as an isolated factor did not reach significance but was included in the model. The p value for the model was p < 1 × 10 -12 . Total thyroidectomy increases risk of early hypocalcaemia when compared to hemithyroidectomy. Gender, diabetes and thyrotoxicosis were also been found to influence the risk. All of these factors are available pre-operatively and can therefore be used to predict a more specific risk for individual patients. It is hoped that this can lead to better informed consent, prevention and better resource allocation.

    Radiotherapy is of great importance in the treatment of pathologic fractures and skeletal lesions bearing the risk of fracture which are induced by malignomas, especially if these are in an advanced stage. In dependence on site and extent of skeletal destruction as well as on the general tumor dissemination, it can be distinguished between palliative radiotherapy and curative radiotherapy aiming at analgesia and remineralization. A retrospective analysis of 27 pathologic fractures and 56 skeletal lesions bearing the risk of fracture in malignoma patients showed an analgetic effect obtained by radiotherapy in 67% of pathological fractures and in 80% of skeletal lesions bearing the risk of fracture, whereas a remineralization could be demonstrated for 33% of pathological fractures and 50% of destructions bearing the risk of fracture. A stabilization of destructions progressing before therapy was found in 55% of pathological fractures and 40% of skeletal lesions bearing the risk of fracture. Thus a partial loading, supported by orthopedic prostheses, was possible for more than 50% of all patients. (orig.) [de

    Full Text Available Objective: to study the impact of a wide spectrum of factors on the development of postoperative delirium in elderly patients in relation to the changes in their cognitive functions depending on the type of anesthesia and period after surgery. Subjects and methods. The study covered 100 patients aged 65—90 years who had been electively operated on under general, regional, and combined anesthesia. Their cognitive status was elevated before and 1, 4, and 7 days after surgery, by using the Mini-Mental State Examination (MMSE schedule. The diagnosis was postoperatively established on the basis of interviews, by applying the diagnostic criteria of ICD-10 and DSM-IV (American Psychiatric Association, 1994 and verified by a psychiatrist’s consultation. Results. Seventeen patients developed delirium within the first two days following surgery. Elevated plasma sodium (p<0.000001, leukocytosis (p<0.00002, and postoperative analgesia mode (p<0.02 proved to be statistically significant risk factors for delirium. Worse results of MMSE tests at all postoperative stages than those obtained prior to surgery were significant (p<0.05. Comparing the results obtained on days 1, 4, and 7 showed a significant cognitive improvement. Analysis indicated no significant differences in MMSE changes between the groups of general, regional, and combined anesthesia at all study stages. Conclusion. In elderly patients, surgery and anesthesia lead to a considerable deterioration of cognitive functions even if the development of delirium can be avoided. There is a significant correlation of the development of delirium with leukocytosis, hypernatremia, and postoperative analgesia mode. Key words: anesthesia, postoperative delirium, cognitive status, MMSE, elderly age.

    The objective of this study was to clarify significant risk factors for postoperative complications in the oral cavity in patients who underwent oral surgery, excluding those with oral cancer. This study reviewed the records of 324 patients who underwent mildly to moderately invasive oral surgery (e.g., impacted tooth extraction, cyst excision, fixation of mandibular and maxillary fractures, osteotomy, resection of a benign tumor, sinus lifting, bone grafting, removal of a sialolith, among others) under general anesthesia or intravenous sedation from 2012 to 2014 at the Department of Oral and Maxillofacial Reconstructive Surgery, Hiroshima University Hospital. Univariate analysis showed a statistical relationship between postoperative complications (i.e., surgical site infection, anastomotic leak) and diabetes (p=0.033), preoperative serum albumin level (p=0.009), and operation duration (p=0.0093). Furthermore, preoperative serum albumin level (oral cavity following oral surgery.

    To identify the potential risk factors for urinary tract infections following midurethral sling procedures. 556 women who underwent midurethral sling procedure due to stress urinary incontinence over a four-year period were reviewed in this retrospective study. Of the study population, 280 women underwent TVT procedures and 276 women underwent TOT procedures. Patients were evaluated at 4-8 weeks postoperatively and were investigated for the occurrence of a urinary tract infection. Patients who experienced urinary tract infection were defined as cases, and patients who didn't were defined as controls. All data were collected from medical records. Multivariate logistic regression model was used to identify the risk factors for urinary tract infection. Of 556 women, 58 (10.4%) were defined as cases while 498 (89.6%) were controls. The mean age of women in cases (57.8±12.9years) was significantly greater than in controls (51.8±11.2years) (purinary tract infection, concomitant vaginal hysterectomy and cystocele repair, TVT procedure and postoperative postvoiding residual bladder volume ≥100ml were more common in cases than in controls. However, in multivariate regression analysis model presence of preoperative urinary tract infection [OR (95% CI)=0.1 (0.1-0.7); p=0.013], TVT procedure [OR (95% CI)=8.4 (3.1-22.3); p=0.000] and postoperative postvoiding residual bladder volume ≥100ml [OR (95% CI)=4.6 (1.1-19.2); p=0.036] were significant independent risk factors for urinary tract infection following midurethral slings CONCLUSION: Urinary tract infection after midurethral sling procedures is a relatively common complication. The presence of preoperative urinary tract infection, TVT procedure and postoperative postvoiding residual bladder volume ≥100ml may increase the risk of this complication. Identification of these factors could help surgeons to minimize this complicationby developing effective strategies. Copyright © 2017. Published by Elsevier B.V.

    The Nun Study was the first cohort study to enroll and follow a large, well-defined population that included demented and non-demented participants, all of whom agreed to donate their brains for research. The inclusion of systematic neuropathologic analysis in this study has resulted in a greater understanding of the role of Alzheimer and vascular pathology in the expression of memory deficits and dementia and has provided data showing that biomarkers for the pathology may be evident many decades earlier in adult life. Findings related to neuropathology in this study have included the following: (1) Although clinical outcomes were strongly correlated with Alzheimer neuropathology, about one-third of the participants fulfilling criteria for neuropathologic Alzheimer's disease (AD) were not demented at the time of death. (2) Brain infarcts by themselves had little effect on cognitive status, but played an important role in increasing the risk of dementia associated with Alzheimer pathology. (3) Hippocampal volume was strongly correlated with Braak neurofibrillary stage even in participants with normal cognitive function. (4) A linguistic characteristic of essays written in early adult life, idea density, had a strong association with not only clinical outcomes in late life, but the severity of Alzheimer neuropathology as well. (5) The effect of apolipoprotein E-e4 on dementia was mediated through Alzheimer, but not vascular pathology.

    The objective of this retrospective study was to determine if dual pathology [DUAL - focal cortical dysplasia (FCD) and mesial temporal sclerosis (MTS)] in patients with left temporal lobe epilepsy is associated with greater risk for cognitive decline following temporal lobectomy than single pathology (MTS only). Sixty-three adults (Mage=36.5years, female: 52.4%) who underwent left anterior temporal lobectomy for treatment of epilepsy (MTS=28; DUAL=35) completed preoperative and postoperative neuropsychological evaluations. The base rate of dual pathology was 55.5%. Repeated measures ANOVAs yielded significant 2-way interactions (group×time) on most measures of language and memory with generally moderate effect sizes. Specifically, patients with MTS only demonstrated postoperative declines, while those with dual pathology remained unchanged or improved. Results suggest that dual pathology may be associated with better cognitive outcome following epilepsy surgery than MTS alone, possibly reflecting limited functionality of the resected tissue or intrahemispheric reorganization of function in the context of a developmental lesion.

    2012-01-01

    There have been increasing concerns regarding the safety of perioperative antitumour necrosis factor (antiTNF) α agents. We performed a literature review to evaluate the postoperative complications associated with perioperative antiTNF use in patients with inflammatory bowel disease. A comprehensive review was performed with a literature search utilizing Pub Med, Cochrane, OVID and EMBASE databases according to published guidelines. To date, there are only data for infliximab. There are three published studies which have assessed postoperative complications with perioperative infliximab use in patients with Crohn's disease (CD), four studies in ulcerative colitis (UC) patients, and one study on both CD and UC patients. Two out of the three studies in CD patients showed no increased postoperative complications associated with perioperative infliximab. Two out of four studies in UC patients also did not show an increase in postoperative complications, and the combined study with CD and UC patients did not show an increased risk as well. Study differences in study designs, patient population and definition of their endpoints. There appears to be a risk of postoperative complications associated with TNF therapy in some patients. Based on these data, careful patient selection and prospective data collection should be performed.

  13. Postoperative persistent chronic pain: what do we know about prevention, risk factors, and treatment

    Full Text Available Abstract Background and objectives: Postoperative persistent chronic pain (POCP is a serious health problem, disabling, undermining the quality of life of affected patients. Although more studies and research have addressed the possible mechanisms of the evolution from acute pain to chronic postoperatively, there are still no consistent data about the risk factors and prevention. This article aims to bring what is in the panorama of the current literature available. Content: This review describes the definition, risk factors, and mechanisms of POCD, its prevention and treatment. The main drugs and techniques are exposed comprehensively. Conclusion: Postoperative persistent chronic pain is a complex and still unclear etiology entity, which interferes heavily in the life of the subject. Neuropathic pain resulting from surgical trauma is still the most common expression of this entity. Techniques to prevent nerve injury are recommended and should be used whenever possible. Despite efforts to understand and select risk patients, the management and prevention of this syndrome remain challenging and inappropriate.

    Several risk factors for the postoperative recurrence of instability after arthroscopic Bankart repair have been reported, but there have been few detailed investigations of the specific risk factors in relation to the type of sport. This study investigated the postoperative recurrence of instability after arthroscopic Bankart repair without additional reinforcement procedures in competitive athletes, including athletes with a large glenoid defect. The purpose of this study was to investigate risk factors related to the postoperative recurrence of instability in athletes. Case-control study; Level of evidence, 3. A total of 115 athletes (123 shoulders) were classified into 5 groups according to type of sport: rugby (41 shoulders), American football (32 shoulders), other collision sports (18 shoulders), contact sports (15 shoulders), and overhead sports (17 shoulders). First, the recurrence rate in each sporting category was investigated, with 113 shoulders followed up for a minimum of 2 years. Then, factors related to postoperative recurrence were investigated in relation to the type of sport. Postoperative recurrence of instability was noted in 23 of 113 shoulders (20.4%). The recurrence rate was 33.3% in rugby, 17.2% in American football, 11.1% in other collision sports, 14.3% in contact sports, and 12.5% in overhead sports. The most frequent cause of recurrence was tackling, and recurrence occurred with tackling in 12 of 16 athletes playing rugby or American football. Reoperation was completed in 11 shoulders. By univariate analysis, significant risk factors for postoperative recurrence of instability included playing rugby, age between 10 and 19 years at surgery, preoperative glenoid defect, small bone fragment of bony Bankart lesion, and capsular tear. However, by multivariate analysis, the most significant factor was not the type of sport but younger age at operation and a preoperative glenoid defect with small or no bone fragment. Compared with the other

  16. Computed tomography findings of early abdominal postoperative complications

    2007-01-01

    Various surgical approaches are used for different abdominal pathological conditions. Postoperative complications occur not infrequently and vary according to the type of the surgery and the clinical context. Nowadays, multidetector computed tomography (MDCT) provides superb anatomic detail and diagnostic accuracy for various intraabdominal pathological processes, even if clinically unsuspected, and it thus has become an essential diagnostic tool for evaluating postoperative insults. Other advantages of abdominal MDCT include its accessibility and its speed, which allow scanning of uncooperative, marginally stable patients. Computed tomography (CT)-guided percutaneous (PC) drainage of postoperative collections is another advantage of CT. Therefore, although CT requires transportation of a critically ill, postoperative patient, it is recommended in any suspicious clinical setting because several conditions require prompt management and a correct diagnosis is crucial. In assessing a patient for suspected postoperative complications, several points should be taken into consideration, including the relevant clinical and laboratory data, the surgical findings, the type of the surgery, the time elapsed since surgery, and the operative technique (either open laparotomy of laparoscopic procedure).

    : To investigate perioperative and postoperative bleeding, complications in patients under therapy with anticoagulant or antiplatelet drugs submitted to oral surgery. To evaluate the risk of bleeding and safety for dental surgery, a retrospective chart review was performed. Medical and dental records of patients taking oral antithrombotic drugs undergoing dental surgery between 2010 and 2015 were reviewed. Results were statistically analyzed using Fisher's exact test, t test or the χ test. One hundred and seventy-nine patients underwent 293 surgical procedures. A total of eight cases of perioperative and 12 episodes of postoperative bleeding were documented. The complications were generally managed with local measures and did not require hospitalization. We found significant association of postoperative hemorrhage with increased perioperative bleeding (P = 0.043) and combination of anticoagulant and antiplatelet therapy (P bleeding is 8.8 times bigger than procedures without perioperative bleeding. Dental surgery in patients under antithrombotic therapy might be carried out without altering the regimen because of low risk of perioperative and postoperative bleeding. However, patients with increased perioperative bleeding should be closely followed up because of postoperative complications risk.

    2016-01-01

    Introduction Presence of cerebrovascular pathology may increase the risk of clinical diagnosis of AD. Methods We examined excess risk of incident clinical diagnosis of AD (probable and possible AD) posed by the presence of lacunes and large infarcts beyond AD pathology using data from the Statistical Modelling of Aging and Risk of Transition (SMART) study, a consortium of longitudinal cohort studies with over 2000 autopsies. We created six mutually exclusive pathology patterns combining three levels of AD pathology (low, moderate or high AD pathology) and two levels of vascular pathology (without lacunes and large infarcts or with lacunes and/or large infarcts). Results The coexistence of lacunes and large infarcts results in higher likelihood of clinical diagnosis of AD only when AD pathology burden is low. Discussion Our results reinforce the diagnostic importance of AD pathology in clinical AD. Further harmonization of assessment approaches for vascular pathologies is required. PMID:28017827

    The aim of this prospective study was to investigate the incidence and clinical features of delirium after total joint arthroplasty, and to establish the potential risk factors for postoperative delirium. A total of 212 consecutive patients undergoing hip or knee arthroplasty, who met the inclusion and exclusive criteria were enrolled. The general characteristics, preoperative and postoperative hematological variables were documented respectively. According to the presence of delirium, all patients were divided into the delirium group and non-delirium group. Univariate and multivariate logistic regression were performed to identify the possible predictors for postoperative delirium. At a minimum of 6months of follow-up, 35 patients were observed with postoperative delirium at an estimated total incidence of 16.5%. The incidence of delirium was statistically higher in hip arthroplasty (22.8%) than that in knee arthroplasty (7.1%). The multivariate regression analysis identified older age (OR=1.590, P=0.023), a history of stroke (OR=190.23, P=0.036), preoperative PaO 2 (OR=1.277, P=0.018) and equivalent fentanyl dose (OR=1.010, P=0.012) as the predictive factors for postoperative delirium after total joint arthroplasty. The incidence of postoperative delirium after total joint arthroplasty is higher than expected. Based on our findings, we suggest that the surgeons should focus on those patients who have these risk factors and ensure the appropriate management to avoid postoperative delirium.

    The prognostic Controlling Nutritional Status (CONUT) score is used to evaluate immuno-nutritional conditions and is a predictive factor of postoperative survival in patients with digestive tract cancer. We retrospectively analyzed clinicopathological features of patients with pathological stage I non-small cell lung cancer (NSCLC) to identify predictors or prognostic factors of postoperative survival and to investigate the role of preoperative CONUT score in predicting survival. We selected 138 consecutive patients with pathological stage I NSCLC treated from August 2005 to August 2010. We measured their preoperative CONUT score in uni- and multivariate Cox regression analyses of postoperative survival. A high CONUT score was positively associated with preoperative serum carcinoembryonic antigen level (p=0.0100) and postoperative recurrence (p=0.0767). In multivariate analysis, the preoperative CONUT score [relative risk (RR)=6.058; 95% confidence interval (CI)=1.068-113.941; p=0.0407), increasing age (RR=7.858; 95% CI=2.034-36.185; p=0.0029), and pleural invasion (RR=36.615; 95% CI=5.900-362.620; pcancer-specific survival (CS), and overall survival (OS), the group with high CONUT score had a significantly shorter RFS, CS, and OS than did the low-CONUT score group by log-rank test (p=0.0458, p=0.0104 and p=0.0096, respectively). The preoperative CONUT score is both a predictive and prognostic factor in patients with pathological stage I NSCLC. This immuno-nutritional score can indicate patients at high risk of postoperative recurrence and death. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    1986-01-01

    Various types of reparative and corrective operations on the shoulder joint are being increasingly undertaken. Defining residual, new, or acutely acquired pathology in the postoperative period is exceedingly difficult because of extensive surgical alterations. Since patients may be symptomatic or recurrently symptomatic postoperatively, judgments must be made regarding the failure of the initial repair, or new superimposed insults. CT double-contrast arthrography, performed in a series of symptomatic patients after shoulder arthroplasty for instability, successfully demonstrated responsible residual or recurrent pathologic processes, including persistent Bankart lesions, glenoid rim fractures, improper hardware placement, and migration of metallic hardware. These and other examples of pathology are illustrated and discussed

    The purpose of this study was to identify risk factors affecting laryngeal pathology in the Korean population and to evaluate the derived prediction model. Cross-sectional study. Data were drawn from the 2008 Korea National Health and Nutritional Examination Survey. The subjects were 3135 persons (1508 male and 2114 female) aged 19 years and older living in the community. The independent variables were age, sex, occupation, smoking, alcohol drinking, and self-reported voice problems. A decision tree analysis was done to identify risk factors for predicting a model of laryngeal pathology. The significant risk factors of laryngeal pathology were age, gender, occupation, smoking, and self-reported voice problem in decision tree model. Four significant paths were identified in the decision tree model for the prediction of laryngeal pathology. Those identified as high risk groups for laryngeal pathology included those who self-reported a voice problem, those who were males in their 50s who did not recognize a voice problem, those who were not economically active males in their 40s, and male workers aged 19 and over and under 50 or 60 and over who currently smoked. The results of this study suggest that individual risk factors, such as age, sex, occupation, health behavior, and self-reported voice problem, affect the onset of laryngeal pathology in a complex manner. Based on the results of this study, early management of the high-risk groups is needed for the prevention of laryngeal pathology. Copyright © 2015 The Voice Foundation. Published by Elsevier Inc.

    Full Text Available Background: Biliary cast syndrome (BCS was a postoperative complication of orthotopic liver transplantation (OLT, and the reason for BSC was considered to relate with ischemic type biliary lesions. This study aimed to evaluate the relationship between BCS following OLT and the hepatic artery resistance index (HARI, and to observe pathological changes and morphology of biliary casts. Methods: Totally, 18 patients were diagnosed with BCS by cholangiography following OLT using choledochoscope or endoscopic retrograde cholangiopancreatography. In addition, 36 patients who did not present with BCS in the corresponding period had detectable postoperative HARI on weeks 1, 2, 3 shown by color Doppler flow imaging. The compositions of biliary casts were analyzed by pathological examination and scanning electron microscopy. Results: HARI values of the BCS group were significantly decreased as compared with the non-BCS group on postoperative weeks 2 and 3 (P 1 (OR = 1.300; 1.223; and 1.889, respectively. The OR of HARI 3 was statistically significant (OR = 1.889; 95% confidence interval = 1.166-7.490; P = 0.024. The compositions of biliary casts were different when bile duct stones were present. Furthermore, vascular epithelial cells were found by pathological examination in biliary casts. Conclusions: HARI may possibly serve as an independent risk factor and early predictive factor of BCS. Components and formation of biliary casts and bile duct stones are different.

    Postoperative pneumonia (POP) is common and results in prolonged hospital stays, higher costs, increased morbidity and mortality. However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC) surgery. Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016. We individually traced each OC patient for a period to discharge from the hospital or 45 days after surgery, whichever occur later. The incidence of POP after major OC surgery with free flap construction or major OC surgery was 11.6% or 4.5%, respectively. Patient-related risk factors for POP were male sex, T stage, N stage, clinical stage and preoperative serum albumin level. Among the investigated procedure-related variables, incision grade, mandibulectomy, free flap reconstruction, tracheotomy, intraoperative blood loss, and the length of the operation were shown to be associated with the development of POP. Postoperative hospital stay was also significantly related to increased incidence of POP. Using a multivariable logistic regression model, we identified male sex, preoperative serum albumin level, operation time and postoperative hospital stay as independent risk factors for POP. Several perioperative risk factors can be identified that are associated with POP. At-risk oral cancer patients should be subjected to intensified postoperative pulmonary care.

    To evaluate the effects of intraoperative protective ventilation on major postoperative respiratory complications and to define safe intraoperative mechanical ventilator settings that do not translate into an increased risk of postoperative respiratory complications. Hospital based registry study. Academic tertiary care hospital and two affiliated community hospitals in Massachusetts, United States. 69,265 consecutively enrolled patients over the age of 18 who underwent a non-cardiac surgical procedure between January 2007 and August 2014 and required general anesthesia with endotracheal intubation. Protective ventilation, defined as a median positive end expiratory pressure (PEEP) of 5 cmH2O or more, a median tidal volume of less than 10 mL/kg of predicted body weight, and a median plateau pressure of less than 30 cmH2O. Composite outcome of major respiratory complications, including pulmonary edema, respiratory failure, pneumonia, and re-intubation. Of the 69,265 enrolled patients 34,800 (50.2%) received protective ventilation and 34,465 (49.8%) received non-protective ventilation intraoperatively. Protective ventilation was associated with a decreased risk of postoperative respiratory complications in multivariable regression (adjusted odds ratio 0.90, 95% confidence interval 0.82 to 0.98, P=0.013). The results were similar in the propensity score matched cohort (odds ratio 0.89, 95% confidence interval 0.83 to 0.97, P=0.004). A PEEP of 5 cmH2O and median plateau pressures of 16 cmH2O or less were associated with the lowest risk of postoperative respiratory complications. Intraoperative protective ventilation was associated with a decreased risk of postoperative respiratory complications. A PEEP of 5 cmH2O and a plateau pressure of 16 cmH2O or less were identified as protective mechanical ventilator settings. These findings suggest that protective thresholds differ for intraoperative ventilation in patients with normal lungs compared with those used for patients

    Cognitive dysfunctions are relatively common in postoperative and critically ill patients. This complication not only compromises recovery after surgery, but, if persistent, it minimizes and compromises surgery itself. Risk factors of postoperative cognitive disorders can be divided into age and comorbidity dependent, and those related to anesthesia and surgery. Cardiovascular, orthopedic and urologic surgery carries high risk of postoperative cognitive dysfunction. It can also occur in other types of surgical treatment, especially in elderly. Among risk factors of cognitive disorders, associated with comorbidity, underlying psychiatric and neurological disorders, substance abuse and conditions with elevation of intracranial pressure are in the first place in postoperative patients. Preoperative and perioperative predisposing conditions for cognitive dysfunction and their incidence were described in our paper. These are: geriatric patients, patients with substance abuse, preexisting psychiatric or cognitive disorders, neurologic disease with high intracranial pressure, cerebrovascular insufficiency, epilepsia, preeclampsia, acute intermittent porphyria, operation type, brain hypoxia, changes in blood glucose level, electrolyte imbalance, anesthetic agents, adjuvant medication and intraoperative awareness. For each of these factors, evaluation, prevention and treatment strategies were suggested, with special regard on anesthetic technique.

    Little has been published about how to prevent pressure ulcers in severely debilitated, immobile patients in intensive care units. To present a possible prevention strategy for postoperative cardiovascular surgery patients at high risk for development of pressure ulcers. Staff chose to implement air fluidized therapy beds, which provide maximal immersion and envelopment as a measure for preventing pressure ulcers in patients who (1) required vasopressors for at least 24 hours and (2) required mechanical ventilation for at least 24 hours postoperatively. Only 1 of 27 patients had a pressure ulcer develop while on the air fluidized therapy bed (February 2008 through August 2008), and that ulcer was only a stage I ulcer, compared with 40 ulcers in 25 patients before the intervention. Patients spent a mean of 7.9 days on the mattress, and the cost of bed rental was approximately $18000, which was similar to the cost of treatment of 1 pressure ulcer in stage III or IV (about $40000) and was considered cost-effective.

    The aim of this article is twofold: (a) to present the principles and the indications of surgical treatment of middle ear pathologies; and (b) to review the imaging findings after middle ear surgery, including the normal postoperative aspects and imaging findings in patients presenting with unsatisfactory surgical results or with suspicion of postoperative complications. This review is intentionally restricted to the most common diseases involving the middle ear: chronic otitis media and otosclerosis. In these specific fields of interest, CT and MR imaging play a very important role in the postoperative follow-up and in the work-up of surgical failures and complications. (orig.)

    Purpose. - To report the results of postoperative radiation therapy in preventing the development of heterotopic bone formation after hip replacement surgery in high-risk patients. Patients and methods. - Between 1991 and 2007, 44 patients were preventively treated with postoperative RT after total hip replacement. In total, 47 hips were treated. All patients were considered at high risk for developing heterotopic bone formation. Most patients (63.5%) were treated because of a history of severe osteoarthritis or ankylosing spondylitis. All patients were treated with shaped parallel-opposed fields with a single fraction of 7 Gy using 6 or 18 MV photons. Most patients (94%) received radiation therapy within 72 hours postoperative and in only three patients radiation therapy was delivered after 72 hours post-surgery (5-8 days). Results. - Minimum follow-up was 1 year. There were 18 females and 26 males. Median age was 63 years (range: 18-80). Treatments were well tolerated and no acute toxicity was seen post-radiation therapy. Only one of the 47 hips (2%) developed heterotopic bone formation. This patient received postoperative radiation therapy to both hips but only developed heterotopic bone formation in one of them. None of the three patients treated beyond 72 hours failed. To date no late toxicity has been observed. Conclusion. - The use of postoperative radiation therapy was an effective and safe treatment in the prevention of heterotopic bone formation in a high-risk group of patients undergoing total hip replacement.

    We studied play behavior of customers of betting offices. A study included 216 people who were surveyed using the Canadian problem gambling index. According to the results of the test, we stratified the sample by the risk of pathological gambling. The high prevalence of people with medium and high risk of pathological gambling was identified. Significant differences in the characteristics of gambling behavior were found. We described the qualitative and quantitative indicators of gaming activity that proved the appearance of the addicted dominant in the high-risk group (changes in the motivational sphere, financial loss, using alternative forms of the game, the regular play activity and low level of the reflection of problems caused by the game).

    Full Text Available Postoperative spinal wound infection is a potentially devastating complication after operative spinal procedures. Despite the utilization of perioperative prophylactic antibiotics in recent years and improvements in surgical technique and postoperative care, wound infection continues to compromise patients’ outcome after spinal surgery. In the modern era of pending health care reform with increasing financial constraints, the financial burden of post-operative spinal infections also deserves consideration. The aim of our work is to give to the reader an updated review of the latest achievements in prevention, risk factors, diagnosis, microbiology and treatment of post-operative spinal wound infections. A review of the scientific literature was carried out using electronic medical databases Pubmed, Google Scholar, Web of Science and Scopus for the years 1973-2012 to obtain access to all publications involving the incidence, risk factors, prevention, diagnosis, treatment of postoperative spinal wound infections. We initially identified 119 studies; of these 60 were selected. Despite all the measures intended to reduce the incidence of surgical site infections in spine surgery, these remain a common and potentially dangerous complication.

    Patients who misuse alcohol are at increased risk for surgical complications. Four weeks of preoperative abstinence decreases the risk of complications, but practical approaches for early preoperative identification of alcohol misuse are needed. To evaluate whether results of alcohol screening with the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) questionnaire-up to a year before surgery-were associated with the risk of postoperative complications. This is a cohort study. Male Veterans Affairs (VA) patients were eligible if they had major noncardiac surgery assessed by the VA's Surgical Quality Improvement Program (VASQIP) in fiscal years 2004-2006, and completed the AUDIT-C alcohol screening questionnaire (0-12 points) on a mailed survey within 1 year before surgery. One or more postoperative complication(s) within 30 days of surgery based on VASQIP nurse medical record reviews. Among 9,176 eligible men, 16.3% screened positive for alcohol misuse with AUDIT-C scores ≥ 5, and 7.8% had postoperative complications. Patients with AUDIT-C scores ≥ 5 were at significantly increased risk for postoperative complications, compared to patients who drank less. In analyses adjusted for age, smoking, and days from screening to surgery, the estimated prevalence of postoperative complications increased from 5.6% (95% CI 4.8-6.6%) in patients with AUDIT-C scores 1-4, to 7.9% (6.3-9.7%) in patients with AUDIT-Cs 5-8, 9.7% (6.6-14.1%) in patients with AUDIT-Cs 9-10 and 14.0% (8.9-21.3%) in patients with AUDIT-Cs 11-12. In fully-adjusted analyses that included preoperative covariates potentially in the causal pathway between alcohol misuse and complications, the estimated prevalence of postoperative complications increased significantly from 4.8% (4.1-5.7%) in patients with AUDIT-C scores 1-4, to 6.9% (5.5-8.7%) in patients with AUDIT-Cs 5-8 and 7.5% (5.0-11.3%) among those with AUDIT-Cs 9-10. AUDIT-C scores of 5 or more up to a year before surgery were

    Purpose: To evaluate the effect of pathologic lymph node status and nodal stage on local control at the primary site in patients with advanced squamous cell carcinomas of the head and neck, treated with radical surgery and postoperative irradiation. Methods and Materials: Fifty-seven patients with advanced squamous cell carcinomas of the oral cavity, oropharynx, hypopharynx, larynx, and supraglottic larynx were analyzed. All patients underwent resection of the primary lesion, neck dissection, and postoperative radiotherapy. Minimum follow-up was 2 years. The median dose to the primary tumor bed was 60.4 Gray (range 39.7-72.0). Besides pathologic nodal status (pN0 vs. pN+) and nodal stage, the following factors were analyzed for their impact on local control: age, gender, T stage, tumor grade, resection margins, interval from surgery to irradiation, dose to the primary site, and overall treatment time. Results: The 3-year actuarial local control rate was 78%. When all patients were analyzed, nodal status (pN0 vs. pN+) did not affect control at the primary site (71% vs. 82%, p = 0.42). Nodal stage (pN0-N2a va. pN2b-N2c) was also not a significant factor for local control (74% vs. 82%, p = 0.57). When only patients with negative margins were analyzed, nodal status again did not impact on local control (79% vs. 90% for pN0 vs. pN+, p = 0.39). On univariate analysis, only tumor grade, margin status, and elapsed days were significant factors for local control. Local control was 85% for patients with negative margins vs. 60% for those with positive margins (p = 0.016). For patients with moderately and poorly differentiated tumors, local control was 86% as compared to 50% for patients with well-differentiated tumors (p = 0.007). When radiotherapy was completed within 50 days, local control was 93% as opposed to 63% for >50 days (p 0.016). On multivariate analysis, only margin status (p = 0.002) and tumor grade (p = 0.007) remained significant. Conclusion: We conclude that

    Most cervical cancer patients worldwide receive surgical treatments, and yet the current International Federation of Gynecology and Obstetrics (FIGO) staging system do not consider surgical-pathologic data. We propose a more comprehensive and prognostically valuable surgical-pathologic staging and scoring system (SPSs). Records from 4,220 eligible cervical cancer cases (Cohort 1) were screened for surgical-pathologic risk factors. We constructed a surgical-pathologic staging and SPSs, which was subsequently validated in a prospective study of 1,104 cervical cancer patients (Cohort 2). In Cohort 1, seven independent risk factors were associated with patient outcome: lymph node metastasis (LNM), parametrial involvement, histological type, grade, tumor size, stromal invasion, and lymph-vascular space invasion (LVSI). The FIGO staging system was revised and expanded into a surgical-pathologic staging system by including additional criteria of LNM, stromal invasion, and LVSI. LNM was subdivided into three categories based on number and location of metastases. Inclusion of all seven prognostic risk factors improves practical applicability. Patients were stratified into three SPSs risk categories: zero-, low-, and high-score with scores of 0, 1 to 3, and ≥4 (P=1.08E-45; P=6.15E-55). In Cohort 2, 5-year overall survival (OS) and disease-free survival (DFS) outcomes decreased with increased SPSs scores (P=9.04E-15; P=3.23E-16), validating the approach. Surgical-pathologic staging and SPSs show greater homogeneity and discriminatory utility than FIGO staging. Surgical-pathologic staging and SPSs improve characterization of tumor severity and disease invasion, which may more accurately predict outcome and guide postoperative therapy.

Revised and updated edition, with a new chapter on gynaecomastia. Ideal aid to the management of patients with benign or indeterminate breast lesions in a multidisciplinary setting. The second edition of this book has been extensively revised and updated. There have been numerous scientific advances in the radiology, pathology and risk assessment of benign breast lesions since the publication of the first edition. The first edition concentrated on screen-detected lesions, which has since been rectified; new symptomatic and screen-detected lesions are discussed in the second edition and include: mastitis and breast abscesses, idiopathic granulomatous mastitis, diabetic mastopathy, phyllodes tumours, gynaecomastia and pseudoangiomatous stromal hyperplasia. The chapters on columnar cell lesions and mucocele-like lesions have been extensively updated. Where applicable, genetic analysis of the benign lesions, which is becoming part of personalised medicine in the field of breast cancer, has been included. The book also presents detailed analyses of the main models, such as the Gail Model, used to assess the subsequent risk of breast cancer in individuals. The current trend in the management of all cancers is preventative. Screening mammography detects early curable cancers as well as indeterminate lesions, the latter of which are invariably pathologically benign. The author has collated important benign lesions and, based on peer-reviewed publications, has documented the relative risk of subsequent cancer to allow the patient and the clinician to implement preventative measures where possible. This book will therefore serve as an essential component of multidisciplinary management of patients with symptomatic and screen-detected benign breast lesions.

    2008-01-01

    Purpose: Identification of patients most likely to benefit from salvage radiotherapy (RT) using postoperative (postop) prostate-specific antigen (PSA) kinetics. Methods and Materials: From 1984 to 2004, 81 patients who fit the following criteria formed the study population: undetectable PSA after radical prostatectomy (RP); pathologically negative nodes; biochemical relapse defined as a persistently detectable PSA; salvage RT; and two or more postop PSAs available before salvage RT. Salvage RT included the whole pelvic nodes in 55 patients and 4 months of total androgen suppression in 56 patients. The median follow-up was >5 years. All relapses were defined as a persistently detectable PSA. Kaplan-Meier and Cox proportional hazards multivariable analysis were performed for all clinical, pathological, and treatment factors predicting for biochemical relapse-free survival (bRFS). Results: There were 37 biochemical relapses observed after salvage RT. The 5-year bRFS after salvage RT for patients with postop prostate-specific antigen velocity ≤1 vs. >1 ng/ml/yr was 59% vs. 29%, p = 0.002. In multivariate analysis, only postop PSAV (p = 0.0036), pre-RT PSA level ≤1 (p = 0.037) and interval-to-relapse >10 months (p = 0.012) remained significant, whereas pelvic RT, hormone therapy, and RT dose showed a trend (p = ∼0.06). PSAV, but not prostate-specific antigen doubling time, predicted successful salvage RT, suggesting an association of zero-order kinetics with locally recurrent disease. Conclusions: Postoperative PSA velocity independently predicts for the failure of salvage RT and can be considered in addition to high-risk features when selecting patients in need of systemic therapy following biochemical failure after RP. For well-selected patients, salvage RT can achieve high cure rates

    Full Text Available Huntington’s Disease (HD is a genetic, neurodegenerative disorder, which specifically affects striatal neurons of the indirect pathway, resulting in a progressive decline in muscle coordination and loss of emotional and cognitive control. Interestingly, predisposition to pathological gambling and other addictions involves disturbances in the same cortico-striatal circuits that are affected in HD, and display similar disinhibition-related symptoms, including changed sensitivity to punishments and rewards, impulsivity, and inability to consider long-term advantages over short-term rewards. Both HD patients and pathological gamblers also show similar performance deficits on risky decision-making tasks, such as the Iowa Gambling Task. These similarities suggest that HD patients are a likely risk group for gambling problems. However, such problems have only incidentally been observed in HD patients. In this review, we aim to characterize the risk of pathological gambling in HD, as well as the underlying neurobiological mechanisms. Especially with the current rise of easily accessible internet gambling opportunities, it is important to understand these risks and provide appropriate patient support accordingly. Based on neuropathological and behavioral findings, we propose that HD patients may not have an increased tendency to seek risks and start gambling, but that they do have an increased chance of developing an addiction once they engage in gambling activities. Therefore, current and future developments of internet gambling possibilities and related addictions should be regarded with care, especially for vulnerable groups like HD patients.

    Preoperative immobility in general surgery patients has been associated with an increased risk of postoperative complications. It is unknown if immobility affects bariatric surgery outcomes. The aim of this study was to determine the impact of immobility on 30-day postoperative bariatric surgery outcomes. This study took place at a university hospital in the United States. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 data set was queried for primary minimally invasive bariatric procedures. Preoperative immobility was defined as limited ambulation most or all the time. Logistic regression analysis was performed to determine if immobile patients are at increased risk (odds ratio [OR]) for 30-day complications. There were 148,710 primary minimally invasive bariatric procedures in 2015. Immobile patients had an increased risk of mortality (OR 4.59, Pbariatric surgery outcomes. Immobile patients have a significantly increased risk of morbidity and mortality. This study provides an opportunity for the development of multiple quality initiatives to improve the safety and perioperative complication profile for immobile patients undergoing bariatric surgery.

    2016-01-01

    Three-dimensional datasets acquired using computed tomography and magnetic resonance imaging are ideally suited for characterization of the aortic root. These modalities offer different advantages and limitations, which must be weighed according to the clinical context. This article provides an overview of current aortic root imaging, highlighting normal anatomy, pathologic conditions, imaging techniques, measurement thresholds, relevant surgical procedures, postoperative complications and potential imaging pitfalls. Patients with a range of clinical conditions are predisposed to aortic root disease, including Marfan syndrome, bicuspid aortic valve, vascular Ehlers-Danlos syndrome, and Loeys-Dietz syndrome. Various surgical techniques may be used to repair the aortic root, including placement of a composite valve graft, such as the Bentall and Cabrol procedures; placement of an aortic root graft with preservation of the native valve, such as the Yacoub and David techniques; and implantation of a biologic graft, such as a homograft, autograft, or xenograft. Potential imaging pitfalls in the postoperative period include mimickers of pathologic processes such as felt pledgets, graft folds, and nonabsorbable hemostatic agents. Postoperative complications that may be encountered include pseudoaneurysms, infection, and dehiscence. Radiologists should be familiar with normal aortic root anatomy, surgical procedures, and postoperative complications, to accurately interpret pre- and postoperative imaging performed for evaluation of the aortic root.

    The aim of this study was to assess the treatment results and toxicity profiles of helical tomotherapy (HT) for postoperative high-risk oral cavity cancer. From December 6, 2006 through October 9, 2009, 19 postoperative high-risk oral cavity cancer patients were enrolled. All of the patients received HT with (84%) or without (16%) chemotherapy. The median follow-up time was 17 months. The 2-year overall survival, disease-free survival, locoregional control, and distant metastasis-free rates were 94%, 84%, 92%, and 94%, respectively. The package of overall treatment time > 13 wk, the interval between surgery and radiation ≤ 6 wk, and the overall treatment time of radiation ≤ 7 wk was 21%, 84%, and 79%, respectively. The percentage of grade 3 mucositis, dermatitis, and leucopenia was 42%, 5% and 5%, respectively. HT achieved encouraging clinical outcomes for postoperative high-risk oral cavity cancer patients with high compliance. A long-term follow-up study is needed to confirm these preliminary findings

    Anxiety disorders are associated with disruptions in both emotional processing and decision making. As a result, anxious individuals often make decisions that favor harm avoidance. However, this bias could be driven by enhanced aversion to uncertainty about the decision outcome (e.g., risk) or aversion to negative outcomes (e.g., loss). Distinguishing between these possibilities may provide a better cognitive understanding of anxiety disorders and hence inform treatment strategies. To address this question, unmedicated individuals with pathological anxiety (n = 25) and matched healthy control subjects (n = 23) completed a gambling task featuring a decision between a gamble and a safe (certain) option on every trial. Choices on one type of gamble-involving weighing a potential win against a potential loss (mixed)-could be driven by both loss and risk aversion, whereas choices on the other type-featuring only wins (gain only)-were exclusively driven by risk aversion. By fitting a computational prospect theory model to participants' choices, we were able to reliably estimate risk and loss aversion and their respective contribution to gambling decisions. Relative to healthy control subjects, pathologically anxious participants exhibited enhanced risk aversion but equivalent levels of loss aversion. Individuals with pathological anxiety demonstrate clear avoidance biases in their decision making. These findings suggest that this may be driven by a reduced propensity to take risks rather than a stronger aversion to losses. This important clarification suggests that psychological interventions for anxiety should focus on reducing risk sensitivity rather than reducing sensitivity to negative outcomes per se.

    Confirmation of the level of scan slices is essential for the CT diagnosis of spinal and spinal-cord diseases. Pre- and postoperative comparison should be made on the same level. For reading of plain CT and CTM, window levels should be identical pre- and postoperatively. Both methods demonstrated the spinal canal, morphology of the spinal cord, and three-Fdimensional pathologic pictures inside and outside the spinal cord. Preoperative CT contributed useful information on the pathologic conditions and selection of surgical procedures and routes. Postoperative plain CT confirmed surgical results, and CTM revealed the spinal cord and the subarachnoid space, as well as the range and degree of decompression from the spinal cord. (Chiba, N.)

    Anatomic pathology laboratory workflow consists of 3 major specimen handling processes. Among the workflow are preanalytic, analytic, and postanalytic phases that contain multistep subprocesses with great impact on patient care. A worldwide representation of experts came together to create a system of metrics, as a basis for laboratories worldwide, to help them evaluate and improve specimen handling to reduce patient safety risk. Members of the Initiative for Anatomic Pathology Laboratory Patient Safety (IAPLPS) pooled their extensive expertise to generate a list of metrics highlighting processes with high and low risk for adverse patient outcomes. : Our group developed a universal, comprehensive list of 47 metrics for patient specimen handling in the anatomic pathology laboratory. Steps within the specimen workflow sequence are categorized as high or low risk. In general, steps associated with the potential for specimen misidentification correspond to the high-risk grouping and merit greater focus within quality management systems. Primarily workflow measures related to operational efficiency can be considered low risk. Our group intends to advance the widespread use of these metrics in anatomic pathology laboratories to reduce patient safety risk and improve patient care with development of best practices and interlaboratory error reporting programs. © American Society for Clinical Pathology 2017.

    Frameless stereotactic aspiration of a hematoma can be the one of the treatment options for spontaneous intracerebral hemorrhage in the basal ganglia. Postoperative hematoma enlargement, however, can be a serious complication of intracranial surgery that frequently results in severe neurological deficit and even death. Therefore, it is important to identify the risk factors of postoperative hematoma growth. During a 13-year period, 101 patients underwent minimally invasive frameless stereotactic aspiration for basal ganglia hematoma. Patients were classified into two groups according to whether or not they had postoperative hematoma enlargement in a computed tomography scan. Baseline demographic data and several risk factors, such as hypertension, preoperative hematoma growth, antiplatelet medication, presence of concomitant intraventricular hemorrhage (IVH), were analysed via a univariate statistical study. Nine of 101 patients (8.9%) showed hematoma enlargement after frameless stereotactic aspiration. Among the various risk factors, concomitant IVH and antiplatelet medication were found to be significantly associated with postoperative enlargement of hematomas. In conclusion, our study revealed that aspirin use and concomitant IVH are factors associated with hematoma enlargement subsequent to frameless stereotactic aspiration for basal ganglia hematoma.

    Surgical care is delivered 24 h a day at most institutions. Alarmingly, some authors have found that certain operative start times are associated with greater morbidity and mortality rates. This effect has been noted in both the public and private sector. Although some of these differences may be related to process, they may also be caused by the human circadian rhythm and corresponding changes in host defenses. We hypothesized that the time of day of an operation would impact the frequency of certain post-operative outcomes significantly. Cases at a single tertiary-care center reported to the American College of Surgeons National Surgical Quality Improvement Program over a 10-year period were identified. Operative start times were divided into six-hour blocks, with 6 am to noon serving as the reference. Standard univariable techniques were applied. Multivariable logistic regression with mixed effects modeling then was used to determine the relation between operative start times and infectious outcomes, controlling for surgeon clustering. Statistical significance was set at p operative infectious complication. Seventy percent of these infections (n = 1,506) were surgical site infections. On univariable analysis considering all cases, nighttime and evening operations had higher rates of post-operative infections than those in performed during the day (9.1% from 6 am to noon; 9.7% from noon to 6 pm; 14.8% from 6 pm to midnight; and 14.4% from midnight to 6 am; p operative start time was not associated with the risk of post-operative infection, even when emergency cases were considered independently. Our data suggest that operative start times have no correlation with post-operative infectious complications. Further work is required to identify the source of the time-dependent outcome variability observed in previous studies.

    Despite best efforts, postoperative complications such as postoperative respiratory failure may occur and prompt recognition of the process and management is required. Postoperative respiratory failure, such as postoperative pneumonia, postpneumonectomy pulmonary edema, acute respiratory distress-like syndromes, and pulmonary embolism, are associated with high morbidity and mortality. The causes of these complications are multifactorial and depend on preoperative, intraoperative, and postoperative factors, some of which are modifiable. The article identifies some of the risk factors, causes, and treatment strategies for successful management of the patient with postoperative respiratory failure. Copyright © 2015 Elsevier Inc.

    Morbidity and mortality after esophagectomy are often related to anastomotic leakage or pneumonia. This study aimed to assess the relationship of intraoperative and postoperative vital parameters with anastomotic leakage and pneumonia after esophagectomy. Consecutive patients who underwent transthoracic esophagectomy with cervical anastomosis for esophageal cancer from January 2012 to December 2013 were analyzed. Univariable and multivariable logistic regression analyses were used to determine potential associations of hemodynamic and respiratory parameters with anastomotic leakage or pneumonia. From a total of 82 included patients, 19 (23%) developed anastomotic leakage and 31 (38%) experienced pneumonia. The single independent factor associated with an increased risk of anastomotic leakage in multivariable analysis included a lower minimum intraoperative pH (OR 0.85, 95% CI 0.77-0.94). An increased risk of pneumonia was associated with a lower mean arterial pressure (MAP) in the first 12 hours after surgery (OR 0.93, 95% CI 0.86-0.99) and a higher maximum intraoperative pH (OR 1.14, 95% CI 1.02-1.27). Interestingly, no differences were noted for the MAP and inotrope requirement between patients with and without anastomotic leakage. A lower minimum intraoperative pH (below 7.25) is associated with an increased risk of anastomotic leakage after esophagectomy, whereas a lower postoperative average MAP (below 83 mmHg) and a higher intraoperative pH (above 7.34) increase the risk of postoperative pneumonia. These parameters indicate the importance of setting strict perioperative goals to be protected intensively. © International Society for Diseases of the Esophagus 2016. All rights reserved.

    The Italian translations of the Pathological Narcissism Inventory (PNI) and Triarchic Psychopathy Measure (TriPM) were administered to 609 community dwelling adults. Participants who scored in the upper 10% of the distribution of the PNI total score were assigned to the group of participants at risk for pathological narcissism, whereas participants who scored in the upper 10% of the distribution of the TriPM total score were assigned to the group of participants at risk for psychopathy. The final sample included 126 participants who were administered the Reading the Mind in the Eyes Test (RMET) and emotion-eliciting movie clips. Participants at risk for pathological narcissism scored significantly lower on the RMET total score than participants who were not at risk for pathological narcissism. Participants at risk for psychopathy showed a significant reduction in the subjective experience of disgust, fear, sadness, and tenderness compared to participants who were not at risk for psychopathy.

    Background: Hashimoto's thyroiditis (HT) has been found to coexist with differentiated thyroid cancer (DTC) in surgical specimens, but an association between the two conditions has been discounted by the medical literature. Therefore, we performed this study to determine any potential relationship between HT and the risk of developing DTC. Methods: We collected data for thyrotropin (TSH), thyroxine (T4), thyroid peroxidase antibody (TPO-Ab) titers, surgical pathology, and weight-based levothyroxine (LT4) replacement dose for patients who were referred for thyroid surgery. Patients with HT at final pathology were studied further. To estimate thyroid function, patients with preoperative hypothyroid HT (Hypo-HT) were divided into three equal groups based on their LT4 replacement: LT4-Low (1.43 μg/kg). A group of preoperatively euthyroid (Euth-HT) patients but with HT by pathology was also studied. All subjects were also grouped based on their TPO-Ab titer in TPO-high (titer >1:1000) or TPO-low/negative (titer thyroid glands (LT4-Low) but not in fully hypothyroid HT (LT4-Mid and LT4-High). High TPO-Ab titers appear to protect against DTC in patients with HT. PMID:24708347

    Postoperative delirium is common after extensive surgery. This study aimed to collate and synthesize published literature on risk factors for delirium in patients with head and neck cancer surgery. Three databases were searched (MEDLINE, Embase, and Cochrane Library) between January 1987 and July 2016. The Newcastle Ottawa Scale (NOS) was adopted to evaluate the study quality. Pooled odds ratios or mean differences for individual risk factors were estimated using the Mantel-Haenszel and inverse-variance methods. They provided a total of 1940 patients (286 with delirium and 1654 without), and predominantly included patients undergoing head and neck cancer surgery. The incidence of postoperative delirium ranged from 11.50% to 36.11%. Ten statistically significant risk factors were identified in pooled analysis. Old age, age >70 years, male sex, duration of surgery, history of hypertension, blood transfusions, tracheotomy, American Society of Anesthesiologists physical status grade at least III, flap reconstruction and neck dissection were more likely to sustain delirium after head and neck cancer surgery. Delirium is common in patients undergoing major head neck cancer surgery. Several risk factors were consistently associated with postoperative delirium. These factors help to highlight patients at risk of developing delirium and are suitable for preventive action. © The Author 2017. Published by Oxford University Press. All rights reserved.

    The occurrence of hepatic steatosis after pancreatectomy is known to be associated with the remnant pancreatic function. However, other risk factors for hepatic steatosis after pancreatectomy remain unknown. The aims of this study were to identify other risk factors in addition to the remnant pancreatic function and elucidate the relationship between postoperative hepatic steatosis and pancreatic exocrine insufficiency in totally pancreatomized patients. Forty-three patients who underwent total pancreatectomy were analyzed. Hepatic steatosis was defined as the attenuation of unenhanced computed tomography values. Clinical findings and laboratory data were compared between patients with and without hepatic steatosis. Sixteen (37.2%) patients developed hepatic steatosis after total pancreatectomy, with marked declines in the Controlling Nutritional Status score and body mass index. Multiple linear regression analysis revealed that the attenuation of computed tomography values was correlated with female sex (P = 0.002), early postoperative serum albumin levels (P = 0.003), and pancreatic enzyme replacement therapy with high-dose pancrelipase (P = 0.032). Postoperative hepatic steatosis after pancreatectomy is associated with sex, malnutrition, and pancreatic exocrine insufficiency. High-dose pancreatic enzyme replacement therapy may have preventive effects on hepatic steatosis occurring after pancreatectomy.

    Over the past two decades, video-assisted thoracoscopic blebectomy and pleurodesis have been used as a safe and reliable option for treatment of spontaneous pneumothorax. The aim of this study is to evaluate the long-term outcome of video-assisted thoracoscopic surgery (VATS) treatment of spontaneous pneumothorax in young patients, and to identify risk factors for postoperative recurrence. We retrospectively analysed the outcome of VATS treatment of spontaneous pneumothorax in our institution in 150 consecutive young patients (age ≤ 40 years) in the years 1997-2010. Treatment consisted of stapling blebectomy and partial parietal pleurectomy. After excluding 16 patients lost to follow-up, in 134 cases [110 men, 24 women; mean age, 25 ± 7 standard deviation years; median follow-up, 79 months (range: 36-187 months)], we evaluated postoperative complications, focusing on pneumothorax recurrence, thoracic dysaesthesia and chronic chest pain. Risk factors for postoperative pneumothorax recurrence were analysed by logistic regression. Of 134 treated patients, 3 (2.2%) required early reoperation (2 for bleeding; 1 for persistent air leaks). Postoperative (90-day) mortality was nil. Ipsilateral pneumothorax recurred in 8 cases (6.0%) [median time of recurrence, 43 months (range: 1-71 months)]. At univariate analysis, the recurrence rate was significantly higher in women (4/24) than in men (4/110; P = 0.026) and in patients with >7-day postoperative air leaks (P = 0.021). Multivariate analysis confirmed that pneumothorax recurrence correlated independently with prolonged air leaks (P = 0.037) and with female gender (P = 0.045). Chronic chest wall dysaesthesia was reported by 13 patients (9.7%). In 3 patients, (2.2%) chronic thoracic pain (analogical score >4) was recorded, but only 1 patient required analgesics more than once a month. VATS blebectomy and parietal pleurectomy is a safe procedure for treatment of spontaneous pneumothorax in young patients, with a 6% long

    Retrospective review of prospective database. To investigate risk factors involved in the development of anterior cervical hematomas and determine any impact on patient outcomes. Postoperative (PO) hematomas after anterior cervical spine surgery require urgent recognition and treatment to avoid catastrophic patient morbidity or death. Current studies of PO hematomas are limited. Cervical spine surgical procedures performed on adults by the senior author at a single academic institution from 1995 to 2012 were evaluated. Demographic data, surgical history, operative data, complications, and neck disability index (NDI) scores were recorded prospectively. Cases complicated by PO hematoma were reviewed, and time until hematoma development and surgical evacuation were determined. Patients who developed a hematoma (HT group) were compared with those that did not (no-HT group) to identify risk factors. NDI outcomes were compared at early (11 mo) time points. There were 2375 anterior cervical spine surgical procedures performed with 17 occurrences (0.7%) of PO hematoma. In 11 patients (65%) the hematoma occurred within 24 hours PO, whereas 6 patients (35%) presented at an average of 6 days postoperatively. All underwent hematoma evacuation, with 2 patients (12%) requiring emergent cricothyroidotomy. Risk factors for hematoma were found to be (1) the presence of diffuse idiopathic skeletal hyperostosis (relative risk = 13.2, 95% confidence interval = 3.2-54.4), (2) presence of ossification of the posterior longitudinal ligament (relative risk = 6.8, 95% confidence interval = 2.3-20.6), (3) therapeutic heparin use (relative risk 148.8, 95% confidence interval = 91.3-242.5), (4) longer operative time, and (5) greater number of surgical levels.

    Full Text Available Serratia marcescens (S. marcescens emerged as an opportunist in the setting of immunodeficiency in the 1970s, when serious infections occurred in San Francisco hospitals after USA. Navy experiments had aerosolized the bacteria to study biologic warfare. We investigate the risks of S. marcescens in San Franciscans who undergo mastectomy with implant reconstruction. From 2007 to 2011, the senior author took breast capsule cultures for all patients at the time of tissue expander exchange/explant. Of the 142 women who had reconstruction, 23 had positive cultures. Only the two patients who were positive for S. marcescens developed clinical infections that required explantation. Both had postoperative chemotherapy with transient neutropenia, and both had close ties to San Francisco. Clinical signs of infection emerged for both patients months after initial surgery, despite having previously well healed incisions. Other patients were culture positive for Pseudomonas, Proteus, Enterococcus and MRSA and did not develop require explant. While the link between San Francisco and S. marcescens is controversial, a patient's geography is a simple screening tool when considering postoperative risks, especially in the immunocompromised. Closer monitoring for neutropenia during chemotherapy, and a lower threshold to administer S. marcescens targeted antibiotics may be warranted in these patients.

    Retrospective case series of surgically treated adolescent patients with scoliosis. To assess the prevalence and independent risk factors for postoperative shoulder imbalance in surgically treated adolescent patients with idiopathic scoliosis. Despite recent reports that have identified risk factors for postoperative shoulder imbalance, the relative risks remain unclear. A retrospective review of 85 consecutive patients treated with thoracic fusion with a minimum 2-year follow-up (mean, 3.1 yr) was conducted to investigate the patient radiographical measurements and demographics. Shoulder height difference (SHD) was measured as the graded height difference of the soft tissue shadows. A SHD more than 2 cm indicated an unbalanced shoulder. Patient demographics and radiographical data were studied to determine risk factors for postoperative SHD. The potential risk factors included age, sex, Risser sign, Cobb angle, flexibility, and apical vertebral rotation (AVR) of the main curve, upper-instrumented vertebra level, SHD, and clavicle chest cage angle difference (CCAD). Univariate and multivariate logistic regression analyses were performed to determine the independent risk factors for postoperative shoulder imbalance. Of the 85 patients, 21 patients presented postoperative shoulder imbalance. The univariate analysis indicated age, Risser sign, Cobb angle of the main curve, AVR of the main curve, and CCAD as risk factors, but the multivariate logistic regression analysis showed that only AVR of the main curve and CCAD were independent risk factors for postoperative shoulder imbalance (AVR, P = 0.04, odds ratio (OR): 3.54; CCAD, P = 0.01, OR: 5.10). Postoperative shoulder imbalance was observed in 25% of the surgically treated adolescent patients. The CCAD and AVR of the main thoracic curve were independent risk factors for postoperative shoulder imbalance in surgically treated patients with adolescent idiopathic scoliosis. The significant correlation between CCAD and

    There is limited data regarding the effects of preoperative dehydration on postoperative renal function. We sought to identify associations between hydration status before operation and postoperative acute renal failure (ARF) in patients undergoing colorectal resection. The NSQIP database was used to examine the data of patients undergoing colorectal resection from 2005 to 2011. We used preoperative blood urea nitrogen (BUN)/creatinine ratio >20 as a marker of relative dehydration. Multivariate analysis using logistic regression was performed to quantify the association of BUN/Cr ratio with ARF. We sampled 27,860 patients who underwent colorectal resection. Patients with dehydration had higher risk of ARF compared to patients with BUN/Cr Dehydration was associated with an increase in mortality of the affected patients (AOR, 2.19; P dehydrated patients. Open colorectal procedures (AOR, 2.67; P = 0.01) and total colectomy procedure (AOR, 1.62; P Dehydration before operation is a common condition in colorectal surgery (incidence of 27.7 %). Preoperative dehydration is associated with increased rates of postoperative ARF, MI, and cardiac arrest. Hydrotherapy of patients with dehydration may decrease postoperative complications in colorectal surgery.

    Full Text Available Background: Considering the important role of pituitary gland in regulating various endocrine axes and its unique anatomical location, various postoperative complications can be anticipated resulting from surgery on pituitary tumors. We examined and categorized the immediate postoperative complications according to various tumor pathologies. Materials and Methods: We carried out a prospective study in 152 consecutive patients and noted various postoperative complications during neurosurgical intensive care unit stay (within 48 hrs of hospital stay in patients undergoing transsphenoidal removal of pituitary tumors. Results: In our series, various groups showed different postoperative complications out of which, cerebrospinal fluid leak was the commonest followed by diabetes insipidus, postoperative nausea and vomiting, and hematoma at operation site. Conclusion: Various immediate postoperative complications can be anticipated in transsphenoidal pituitary surgery even though, it is considered to be relatively safe.

    Roentgenoendovascular functional thyroidectomy was used to suppress the pathological activity of the thyroid in postoperative recurrent goiter. The method consists in vascular isolation of hyperplastic stump of the thyroid by catheterization of the left and right thyroid arteries, followed by their material occlusion. For embolization, a wide spectrum of nonlyzed synthetic, organic, and inorganic materials were used. The results of roentgenoendovascular functional thyroidectomy in 14 patients with postoperative recurrent goiter are analyzed. The advantages of roentgenoendovascular occlusion of the thyroid arteries before subtotal thyroidectomy are emphasized. A stabile clinical and hormonal remission and reduction of the thyroid in size to stage 1 were observed during three years following roentgenoendovascular intervention [ru

    The pattern and factors influencing the lung function recovery in the first postoperative days are still not fully elucidated, especially in patients at increased risk. Prospective study on 60 patients at increased risk, who underwent a lung resection for primary lung cancer. complete resection and one or more known risk factors in form of COPD, cardiovascular disorders, advanced age or other comorbidities. Previous myocardial infarction, myocardial revascularization or stenting, cardiac rhythm disorders, arterial hypertension and myocardiopathy determined the increased cardiac risk. The severity of COPD was graded according to GOLD criteria. The trend of the postoperative lung function recovery was assessed by performing spirometry with a portable spirometer. Cardiac comorbidity existed in 55%, mild and moderate COPD in 20% and 35% of patients respectively. Measured values of FVC% and FEV1% on postoperative days one, three and seven, showed continuous improvement, with significant difference between the days of measurement, especially between days three and seven. There was no difference in the trend of the lung function recovery between patients with and without postoperative complications. Whilst pO2 was decreasing during the first three days in a roughly parallel fashion in patients with respiratory, surgical complications and in patients without complications, a slight hypercapnia registered on the first postoperative day was gradually abolished in all groups except in patients with cardiac complications. Extent of the lung resection and postoperative complications do not significantly influence the trend of the lung function recovery after lung resection for lung cancer.

    Spinal epidural hematoma (SEH) is a rare postoperative complication but can result in catastrophic neurological deficits requiring immediate surgical evacuation of the hematoma. Knowing the risk factors for postoperative SEH can help surgeons stratify patients. Therefore, to identify possible risk factors for postoperative SEH, we reviewed 6 clinical cases and examined the relation between postoperative hypertension and the risk of developing SEH. A retrospective review was conducted of 1282 consecutive patients who underwent spinal surgery at a single institution between 2010 and 2015. Of this cohort, 6 patients developed symptomatic SEH and underwent emergency hematoma evacuation. The 6 SEH patients were evaluated for previously described risk factors of postoperative hematoma formation. In particular, postoperative blood pressure measurements were reviewed. The incidence of postoperative symptomatic SEH was 0.468%. Two patients developed SEH secondary to a nonfunctional surgical drain in the early postoperative period (5 or 12 h post-surgery). Preoperative and postoperative hypertension was observed in 4 patients who developed SEH at greater than or equal to 48 h following surgery. Our findings suggest that rigorous postoperative blood pressure control may decrease the risk of SEH. © 2017 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

    Studies focused on postoperative outcome after oncologic right colectomy are lacking. The main objective was to determine pre-/intraoperative risk factors for anastomotic leak after elective right colon resection for cancer. Secondary objectives were to determine risk factors for postoperative morbidity and mortality. Fifty-two hospitals participated in this prospective, observational study (September 2011-September 2012), including 1102 patients that underwent elective right colectomy. Forty-two pre-/intraoperative variables, related to patient, tumor, surgical procedure, and hospital, were analyzed as potential independent risk factors for anastomotic leak and postoperative morbidity and mortality. Anastomotic leak was diagnosed in 93 patients (8.4 %), and 72 (6.5 %) of them needed radiological or surgical intervention. Morbidity, mortality, and wound infection rates were 29.0, 2.6, and 13.4 %, respectively. Preoperative serum protein concentration was the only independent risk factor for anastomotic leak (p leaks, stapled technique (p = 0.03, OR 2.1) and preoperative serum protein concentration (p = 0.004, OR 0.6 g/dL) were identified as the only two independent risk factors. Age and preoperative serum albumin concentration resulted to be risk factors for postoperative mortality. Male gender, pulmonary or hepatic disease, and open surgical approach were identified as risk factors for postoperative morbidity, while male gender, obesity, intraoperative complication, and end-to-end anastomosis were risk factors for wound infection. Preoperative nutritional status and the stapled anastomotic technique were the only independent risk factors for clinically relevant anastomotic leak after elective right colectomy for cancer. Age and preoperative nutritional status determined the mortality risk, while laparoscopic approach reduced postoperative morbidity.

    Few studies have investigated Internet Addiction (IA) in adolescents in relation to personality characteristics. The aim of this study was to determine whether personality differences exist between adolescents with problematic/pathological Internet use and those with normal Internet use. Our hypothesis was that certain psychopathological personality traits may predispose to the development of maladaptive Internet use. The Internet Addiction Test (IAT) and the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) were administered to a sample of 224 high school students. Analysis of IAT scores showed that 24.6% of the students had problematic Internet use and 1.6% had IA. Comparison of the MMPI-A scores between subjects with normal Internet use and those with problematic or pathological use based on the IAT score showed that some subscales, including schizophrenia and bizarre mentation, were strongly associated with problematic/pathological Internet use. Also, male sex, attending a vocational school, and unhappy childhood were found to be risk factors for IA. Certain psychological dimensions regarding mood and the psychotic area, as well as low self-esteem, family, school and conduct problems could represent risk factors. Taken together, our data suggest a personality profile, with problems at various levels in subjects with problematic or pathological Internet use. Copyright © 2016. Published by Elsevier B.V.

    2015-01-06

    Most patients with newly diagnosed differentiated thyroid carcinoma have tumors with low risk of mortality and recurrence. Standard therapy has been total or near total thyroidectomy followed by postoperative radioiodine remnant ablation (RRA). Although RRA provides benefits, current clinical guidelines do not recommend it universally, since an increase in disease-free survival or a decrease in mortality in low risk patients has not been demonstrated so far. Advancements in our understanding of the biological behavior of thyroid cancer have been translated into the clinic in a personalized approach to the patients based on their individual risk of recurrence and mortality. Current evidence suggests that RRA is not indicated in most low-risk patients, especially those with papillary carcinomas smaller than 1cm, without extrathyroidal extension, unfavorable histology, lymph node involvement or distant metastases. Follow-up of these patients with serial measurements of serum thyroglobulin and neck ultrasound is adequate. Careful evaluation of all risk factors of clinical relevance will allow a more realistic assessment of each individual patient. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    This study was undertaken to evaluate the efficacy of postoperative radiotherapy, and to investigate the prognostic factors for FIGO stages IB-IIB cervical cancer patients who were treated with simple hysterectomy, or who had high-risk factors following radical hysterectomy and pelvic lymph node dissection. Between March 1986 and December 1998, 58 patients, with FIGO stages IB-IIB cervical cancer were included in this study, The indications for postoperative radiation therapy were based on the pathological findings, including lymph node metastasis, positive surgical margin, parametrial extension, Iymphovascular invasion, invasion of more than half the cervical stroma, uterine extension and the incidental finding of cervix cancer following simple hysterectomy. All patients received external pelvic radiotherapy, and 5 patients, received an additional intracavitary radiation therapy. The radiation dose from the external beam to the whole pelvis was 45 - 50 Gy. Vagina cuff irradiation was performed, after completion of the external beam irradiation, al a low-dose rate of CS-137, with the total dose of 4488-4932 chy (median: 4500 chy) at 5 mm depth from the vagina surface. The median follow-up period was 44 months (15-108 months), The 5-yr actuarial local control rate, distant free survival and disease-free survival rate were 98%, 95% and 94%, respectively. A univariate analysis of the clinical and pathological parameters revealed that the clinical stage (p=0.0145), status of vaginal resection margin (p=0.0002) and parametrial extension (p=0.0001) affected the disease-free survival. From a multivariate analysis, only a parametrial extension independently influenced the disease-free survival. Five patients (9%) experienced Grade 2 late treatment-related complications, such as radiation proctitis (1 patient), cystitis (3 patients) and lymphedema of the leg (1 patient). No patient had grade 3 or 4 complications. Our results indicate that postoperative radiation therapy can

    The aim of this study was to determine the effect of dexamethasone and ketolgan on postoperative nausea and vomiting and to evaluate risk factors for postoperative nausea and vomiting. A prospective, double-blind, randomized clinical study was carried out. One hundred fifty-three ASA I-II women undergoing laparoscopic gynecologic operations were randomized into three groups: dexamethasone group (n=51), ketolgan group (n=51), and control group (n=51). Patients in the dexamethasone group were given 4 mg of dexamethasone intravenously before the induction of general anesthesia, the ketolgan group received 30-mg ketolgan intravenously, and control group did not receive any medication. The incidence and severity of postoperative nausea and vomiting were registered 24 hours after the surgery. The incidence of postoperative nausea and vomiting in the dexamethasone group was 13.8%; in the ketolgan group, 37.3%, and in the control group, 58.9% (P=0.026). Patients with a history of migraine suffered from postoperative nausea and vomiting in 70.3% of cases and migraine-free patients in 25.8% of cases (P=0.015). Opioids for postoperative analgesia increased the incidence of postoperative nausea and vomiting as compared with nonsteroidal anti-inflammatory drugs (P=0.00002). Preoperative medication with dexamethasone significantly reduces the incidence of postoperative nausea and vomiting. Avoidance of opioids for postoperative analgesia reduces the incidence of postoperative nausea and vomiting. Migraine and motion sickness are independent risk factors for postoperative nausea and vomiting.

    This retrospective case control study aimed to evaluate the feasibility of using Estimation of Physiological Ability and Surgical Stress (E-PASS) and Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) systems in patients undergoing spinal surgical procedures. Degenerative spine disease has increased in incidence in aging societies, as has the number of older adult patients undergoing spinal surgery. Many older adults are at a high surgical risk because of comorbidity and poor general health. We retrospectively reviewed 217 patients who had undergone spinal surgery at a single tertiary care. We investigated complications within 1 month after surgery. Criteria for both skin incision in E-PASS and operation magnitude in the POSSUM system were modified to fit spine surgery. We calculated the E-PASS and POSSUM scores for enrolled patients, and investigated the relationship between postoperative complications and both surgical risk scoring systems. To reinforce the predictive ability of the E-PASS system, we adjusted equations and developed modified E-PASS systems. The overall complication rate for spinal surgery was 22.6%. Forty-nine patients experienced 58 postoperative complications. Nineteen major complications, including hematoma, deep infection, pleural effusion, progression of weakness, pulmonary edema, esophageal injury, myocardial infarction, pneumonia, reoperation, renal failure, sepsis, and death, occurred in 17 patients. The area under the receiver operating characteristic curve (AUC) for predicted postoperative complications after spine surgery was 0.588 for E-PASS and 0.721 for POSSUM. For predicted major postoperative complications, the AUC increased to 0.619 for E-PASS and 0.842 for POSSUM. The AUC of the E-PASS system increased from 0.588 to 0.694 with the Modified E-PASS equation. The POSSUM system may be more useful than the E-PASS system for estimating postoperative surgical risk in patients undergoing

    Aspergillus fungi can cause serious infections, including intra-abdominal infection, particularly in patients with compromised immune system. Described in the present report is case of 46-year-old female patient who had undergone laparoscopic cholecystectomy (LC) at another healthcare facility. In early postoperative period, she had increasing complaints of swelling, nausea, and vomiting. On postoperative 19th day, she was referred to our clinic with diagnosis of acute abdomen. Surgery was performed with suspected possibility of bile leakage. However, pathological examination of soft, yellow-green mass found in subhepatic space determined it was fungus ball caused by fungi of the genus Aspergillus. Patient was diagnosed postoperative intra-abdominal aspergillosis (IAA).

    Conclusion: Swedish anaesthesia personnel are concerned about the risk of postoperative cognitive side-effects but are more concerned about cardiovascular/pulmonary risks, pain, PONV and the rare event of awareness. Most respondents were not convinced about the use of depth-of-anaesthesia monitors. There is a need to improve knowledge around risk factors, prevention and management of postoperative cognitive side effects.

    Full Text Available Lingual nerve injury or neuropraxia is a rare but potentially serious perioperative complication following airway instrumentation during general anesthesia. This study explored the the incidence and perioperative risk factors for lingual nerve injury in patients receiving laryngeal mask (LMA or endotracheal (ETGA general anesthesia in a single center experience.All surgical patients in our hospital who received LMA or ETGA from 2009 to 2013 were included, and potential perioperative risk factors were compared. Matched controls were randomly selected (in 1:5 ratio from the same database in non-case patients. A total of 36 patients in the records had reported experiencing tongue numbness after anesthesia in this study. Compared with the non-case surgical population (n = 54314, patients with tongue numbness were significantly younger (52.2±19.5 vs 42.0±14.5; P = 0.002 and reported lower ASA physical statuses (2.3±0.7 vs 1.6±0.6; P<0.001. Patient gender, anesthesia technique used, and airway device type (LMA or ETGA did not differ significantly across the two groups. A significantly higher proportion of patients underwent operations of the head-and-neck region (38.9 vs 15.6%; P = 0.002 developed tongue numbness after anesthesia. Multivariate logistic regression analysis indicated that head-and-neck operations remained the most significant independent risk factor for postoperative lingual nerve injury (AOR 7.63; 95% CI 2.03-28.70.The overall incidence rate of postoperative lingual neuropraxy was 0.066% in patients receiving general anesthesia with airway device in place. Young and generally healthy patients receiving head-and-neck operation are at higher risk in developing postoperative lingual neuropraxy. Attention should be particularly exercised to reduce the pressure of endotracheal tube or laryngeal mask on the tongue during head-and-neck operation to avert the occurrence of postoperative lingual neuropraxy.

    Impaired postural balance due to somatosensory data loss with mechanical instability has been shown in patients with ACL deficiency. To assess postural balance in patients with ACL insufficiency prior to surgery and following reconstruction with serial evaluations. Thirty patients (mean age of 27.7 ± 6.7 years) who underwent arthroscopic reconstruction of ACL with bone-patellar tendon-bone autograft were examined for clinical and functional variables at preoperative day and postoperative 12th week. Posturographic analysis were performed by using Tetrax Interactive Balance System (Sunlight Medical Ltd, Israel) at preoperative day, at 4th, 8th, and 12th weeks following reconstruction. Data computed by posturographic software by the considerations of the oscillation velocities of body sways is fall risk as a numeric value (0-100, lower values indicate better condition). All of the patients (mean age of 27.7 ± 6.7 years) had significant improvements for clinical, functional evaluations and fall risk (pfall risk was within high-risk category (59.9 ± 22.8) preoperatively. The highest fall risk was detected at postoperative 4th week. Patients had high fall risk at 8th week similar to preoperative value. Mean fall risk decreased to low level risk at 12th week. Preoperative symptom duration had relationships with preoperative fall risk and postoperative improvement of fall risk (p= 0.001, r= -0.632, p= 0.001, r= -0.870, respectively). The improvement of fall risk was higher in patients with symptoms shorter than 6 months (p= 0.001). According to these results, mean fall risk of patients with ACL insufficiency was within high risk category preoperatively, and fall risk improves after surgical reconstruction, but as the duration of complaints lengthens especially longer than 6 months, the improvement of fall risk decreases following reconstruction.

    Objective The purpose of this study was to determine whether new-onset transient postoperative atrial fibrillation (TPAF) affects mortality rates after abdominal aortic aneurysm (AAA) repair and to identify predictors for the development of TPAF. Methods Patients who underwent open aortic repair or endovascular aortic repair for a principal diagnosis AAA were retrospectively identified using the Healthcare Cost and Utilization Project-State Inpatient Database (Florida) for 2007 to 2011 and monitored longitudinally for 1 year. Inpatient and 1-year mortality rates were compared between those with and without TPAF. TPAF was defined as new-onset atrial fibrillation that developed in the postoperative period and subsequently resolved in patients without a history of atrial fibrillation. Cox proportional hazards models, adjusted for age, gender, comorbidities, rupture status, and repair method, were used to assess 1-year survival. Predictive models were built with preoperative patient factors using Chi-squared Automatic Interaction Detector decision trees and externally validated on patients from California. Results A 3.7% incidence of TPAF was identified among 15,148 patients who underwent AAA repair. The overall mortality rate was 4.3%. The inpatient mortality rate was 12.3% in patients with TPAF vs 4.0% in those without TPAF. In the ruptured setting, the difference in mortality was similar between groups (33.7% vs 39.9%, P = .3). After controlling for age, gender, comorbid disease severity, urgency (ruptured vs nonruptured), and repair method, TPAF was associated with increased 1-year postoperative mortality (hazard ratio, 1.48; P predict an individual's probability of developing TPAF at the point of care. Conclusions The development of TPAF is associated with an increased risk of mortality in patients undergoing repair of nonruptured AAA. Predictive modeling can be used to identify those patients at highest risk for developing TPAF and guide interventions to improve

    Sarcopenia is the progressive loss of muscle mass and strength, and has a risk of adverse outcomes such as disability, poor quality of life and death. As prognosis depends not only on disease aggressiveness, but also on a patient's physical condition, sarcopenia can predict survival in patients with various cancer types. However, its effects on postoperative prognosis in patients with localized non-small cell lung cancers (NSCLC) have never been reported. We retrospectively investigated 215 male patients with pathological Stage I NSCLC. L3 muscle index is defined as the cross-section area of muscle at the third lumbar vertebra level, normalized for height, and is a clinical measurement of sarcopenia. We then investigated the effect of preoperative sarcopenia on their postoperative prognosis. Our 215 subjects included 30 patients with sarcopenia. Sarcopenia was significantly associated with body mass index, nutritional condition, serum CYFRA 21-1 level and pathological stage, but not with preoperative respiratory function or performance status. Frequency of postoperative complications, length of postoperative hospital stay, thoracic drainage period or causes of death were not correlated with the presence of sarcopenia. The sarcopenia group had a significantly shorter median overall survival (32 months) than the no-sarcopenia group. Sarcopenia might not affect short-term outcomes in patients with early-stage lung cancer. Sarcopenia was a predictor of poor prognosis in male patients with Stage I NSCLC. As sarcopenic patients with NSCLC patients are at risk for significantly worse outcomes, their treatments require careful planning, even for those with Stage I disease. © The Author 2017.

    Postoperative delirium (POD) in Surgical Intensive Care patients is an important independent outcome determinant. The purpose of our study was to evaluate the incidence and determinants of POD. Prospective cohort study conducted during a period of 10 months in a Post-Anesthesia Care Unit (PACU) with five intensive care beds. All consecutive adult patients submitted to major surgery were enrolled. Demographic data, perioperative variables, length of stay (LOS) and the mortality at PACU, hospital and at 6-months follow-up were recorded. Postoperative delirium was evaluated using the Intensive Care Delirium Screening Checklist (ICDSC). Descriptive analyses were conducted and the Mann-Whitney test, Chi-square test or Fisher's exact test were used for comparisons. Logistic regression analysis evaluated the determinants of POD with calculation of odds ratio (OR) and its confidence interval 95% (95% CI). There were 775 adult PACU admissions and 95 patients had exclusion criteria. Of the remaining 680 patients, 128 (18.8%) developed POD. Independent determinants of POD identified were age, ASA-PS, emergency surgery and total amount of fresh frozen plasma administered during surgery. Patients with delirium had higher mortality rates, were more severely ill and stayed longer at the PACU and in the hospital. POD was an independent risk factor for hospital mortality There was a high incidence of delirium had a high incidence in intensive care surgical patients. POD was associated with worse severity of disease scores, longer LOS in hospital, and in PACU and higher mortality rates. The independent risk factors for POD were age, ASAPS, emergency surgery and the amount of plasma administered during surgery. Copyright © 2012 Elsevier Editora Ltda. All rights reserved.

    Objectives: To assess the prognostic value of combined evaluation of preoperative CT findings and pre/postoperative serum carcinoembryonic antigen (CEA) levels for pathological stage I lung adenocarcinoma. Methods: This retrospective study included 250 consecutive patients who underwent complete resection for ≤3-cm pathological stage I (T1–2aN0M0) adenocarcinomas (132 men, 118 women; mean age, 67.8 years). Radiologists evaluated following CT findings: maximum tumor diameter, percentage of solid component (%solid), air bronchogram, spiculation, adjacency of bullae or interstitial pneumonia (IP) around the tumor, notch, and pleural indent. These CT findings, pre/postoperative CEA levels, age, gender, and Brinkman index were assessed by Cox proportional hazards model to determine the best prognostic model. Prognostic accuracy was examined using the area under the receiver operating characteristic curve (AUC). Results: Median follow-up period was 73.2 months. In multivariate analysis, high %solid, adjacency of bullae or IP around the tumor, and high postoperative CEA levels comprised the best combination for predicting recurrence (P < 0.05). A combination of these three findings had a greater accuracy in predicting 5-year disease-free survival than did %solid alone (AUC = 0.853 versus 0.792; P = 0.023), with a sensitivity of 85.7% and a specificity of 74.3% at the optimal threshold. The best cut-off values of %solid and postoperative CEA levels for predicting high-risk patients were ≥48% and ≥3.7 ng/mL, respectively. Conclusion: Compared to %solid alone, combined evaluation of %solid, adjacency of bullae or IP change around the tumor, and postoperative CEA levels improves recurrence prediction for stage I lung adenocarcinoma.

    Post-operative infection impacts the quality of patient care, prolongs the length of hospital stay, and utilizes more health care resources. The purpose of this study was to compare the rates of surgical site infection among three major surgical procedures for treating patients with colon pathology. The location of colon resection impacts the post-operative infection rate. A retrospective cohort study was conducted by using the 2006 Nationwide Inpatient Sample. Adult patients (age ≥18 yr) with colon diseases are the population of interest. The disease status and procedures were categorized according to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Patients with a primary diagnosis of diverticulosis of the colon without hemorrhage (ICD-9-CM codes: 562.11 and 562.12) or malignant neoplasm of the colon (ICD-9-CM codes: 153.x, where x represents the possible digits within this ICD-9-CM code category), with procedures of open and other right hemicolectomy (ORH; ICD-9-CM code: 45.73) or open and other left hemicolectomy (OLH; ICD-9-CM code: 45.75), or open and other sigmoidectomy (OS; ICD-9-CM code: 45.76) were included for this study. The primary measured outcome for the study was surgical site infection. There were an estimated 26,381 ORH procedures, 9,558 OLH procedures, and 31,656 OS procedures performed in 2006. There was a significant difference among procedures with respect to their age distributions (mean [standard error]: ORH vs. OLH vs. OS=70.5 [0.2] vs. 63.8 [0.3] vs. 59.5 [0.2] yr, pinfection rates: ORH vs. OLH vs. OS=2.9% vs. 5.6% vs. 4.9%, pinfection for OLH (AOR [95% CI]: 1.31 [1.04-1.64], p=0.02) compared with OS. Different sites of colon operations were associated with different risks of surgical site infections. Accordingly, appropriate pre-operative measures should address these differences.

    Singultus, or hiccups, is a common medical condition. Despite exponential leaps in medicine, the pathophysiologic cause remains poorly defined. Persistent singultus has been associated with conditions such as pulmonary embolism and myocardial infarction. Singultus is also a well-known postoperative complication. The criterion standard of care for patients with singultus involves ruling out lethal pathologic causes, attempting physical stimulation with Valsava maneuvers or drinking water, and, if no relief has been achieved, administering drugs to ease the symptoms. The authors report a case of a man whose postoperative singultus was successfully managed with osteopathic manipulative treatment. This approach addresses many of the possible underlying neuromechanical causes of the aberrant reflex with minimal potential for adverse effects. Physicians should consider osteopathic manipulative treatment in the care of patients with singultus. © 2015 The American Osteopathic Association.

    A wide body of evidence indicates that environmental and occupational risk factors are associated with the development of pathological disorders. The pathogenic role of many environmental pollutants or occupational contaminants is already known and has been extensively investigated. However, the molecular mechanisms of action and the pathogenic effects of many substances remain unknown. Therefore, there is a need to better investigate the role of new environmental and occupational risk factors that may cause the development of several diseases.

    To investigate the effects of early enteral immunonutrition on postoperative immune function and rehabilitation of gastric cancer patients with nutritional risk. New hospitalized patients with gastric cancer were evaluated the nutrient status based on NRS 2002. The patients who scored between 3 to 5 points were randomized into two groups(30 cases for each group), and those in experimental group were given 7-d early postoperative enteral immune nutrition, those in control group were given normal nutrition. The immune indexes (CD3 + , CD4 + , CD8 + and CD4 + /CD8 + ) and nutritional indexes(transferrin, pre-albumin, albumin) were measured before operation and at the 3 rd and 7 th day postoperatively. In addition, the first flatus time, gastrointestinal adverse reactions and complications, length of hospital stays were compared between the two groups. The level of CD4 + /CD8 + and transferrin, pre-albumin, albumin in experimental group were significantly higher than those in control group at the third and seventh day postoperatively ( P 0.05). Early enteral immunonutrition can effectively promote the recovery of nutritional status and immune function in gastric cancer patients with nutrition risk.

    Several studies have demonstrated that child maltreatment (psychological, physical, and sexual abuse, and neglect) may be a significant factor in the development of pathological personality traits that increase the risk for suicidal ideation and behavior from adolescence to adulthood. Currently, the challenge is to understand how different forms of early negative experiences render an individual prone to develop specific personality traits and, in turn, be more vulnerable to suicide risk. To understand the relationship between childhood maltreatment and personality dimensions in suicide risk, our study aims to explore the role of self-criticism and dependency, two different pathological personality traits, as potential mediators of the link between different types of childhood maltreatment and suicide risk in young adults. For this purpose, 306 students from three Italian public universities were recruited. We used the Italian version of the Childhood Experience of Care and Abuse Questionnaire (CECA.Q) to assess experiences of lack of care by parents (i.e., antipathy and neglect) as well as psychological and physical abuse before the age of 17 years. The Depressive Experiences Questionnaire (DEQ) was used to assess the personality dimensions of self-criticism and dependency, and the Suicide History Self-Rating Screening Scale was administered to assess suicide risk. Results revealed that lack of care and psychological abuse were significantly associated with suicide risk and this association was partially mediated by the maladaptive personality dimension of self-criticism. These findings suggest that the combined effect of specific forms of dysfunctional parental behavior during childhood and the development of rigid and dysfunctional negative personality traits may increase the risk for suicidal ideation and behavior during adulthood.

    The present study investigated the therapeutic effect of radiofrequency ablation on children with supraventricular tachycardia (SVT), and explored the risk factors for postoperative recurrence. A total of 312 patients with pediatric SVT were selected in the Affiliated Children's Hospital of Xuzhou Medical University from April, 2011 to March, 2017. All the patients were subjected to radiofrequency ablation, and clinical data were retrospectively analyzed. Tilt table test was performed before and after treatment, and heart rate, systolic and diastolic blood pressure before and after treatment were compared. Plasma levels of D-dimer (D-D), platelet α-granule membrane protein (GMP-140) and thrombin-antithrombin III complex (TAT) were detected by enzyme-linked immunosorbent assay before treatment, immediately after radiofrequency oblation, and at 1, 3 and 7 days after treatment. Treatment outcomes were compared between the atrioventricular reentrant tachycardia (AVRT) and atrioventricular nodal reentrant tachycardia (AVNRT) groups. Risk factors for postoperative recurrence were analyzed. Supine position heart rate after treatment was not significantly different from that before treatment (P>0.05), while the upright position heart rate was significantly increased after treatment (P0.05). No significant difference in radiofrequency ablation rate, recurrence rate and incidence of complications were found between the AVRT and AVNRT groups (P>0.05). After radiofrequency, the levels of D-D, GMP-140 and TAT ablation showed an upward trend, but decreased at day 7 to reach preoperative levels. Logistic regression analysis revealed that residual slow pathway (OR=6.718, P=0.005) and inaccurate targeting (OR=2.815, P=0.007) were independent risk factors for postoperative recurrence (Pradiofrequency ablation can damage the cardiac vagal nerve, resulting in an increase in the heart rate after ablation during the course of the tilt table test and changed hemagglutination state

    Postoperative nausea and vomiting (PONV) are commonly feared after general anesthesia and can impact results. The primary aim of our study was to examine incidence and severity of PONV by investigating complete response, or absence of PONV, to prophylaxis used in patients undergoing DIEP flaps. Our secondary aims were definition of the magnitude of risk, state of the art of interventions, clinical sequelae of PONV, and interaction between these variables, specifically for DIEP patients. A retrospective chart review occurred for 29 patients undergoing DIEP flap breast reconstruction from September 2007 to February 2008. We assessed known patient and procedure-specific risks for PONV after DIEPs, prophylactic antiemetic regimens, incidence, and severity of PONV, postoperative antiemetic rescues, and effects of risks and treatments on symptoms. Three or more established risks existed in all patients, with up to seven risks per patient. Although 90% of patients received diverse prophylaxis, 76% of patients experienced PONV, and 66% experienced its severe form, emesis. Early PONV (73%) was frequent; symptoms were long lasting (average 20 hours for nausea and emesis); and multiple rescue medications were frequently required (55% for nausea, 58% for emesis). Length of surgery and nonsmoking statistically significantly impacted PONV. We identify previously undocumented high risks for PONV in DIEP patients. High frequency, severity, and refractoriness of PONV occur despite standard prophylaxis. Plastic surgeons and anesthesiologists should further investigate methods to optimize PONV prophylaxis and treatment in DIEP flap patients. © 2013 Wiley Periodicals, Inc.

    Avascular necrosis (AVN) of the femoral head is a major complication after internal fixation of a femoral neck fracture and determines the functional prognosis. We investigated postoperative bone single-photon emission computed tomography/computed tomography (SPECT/CT) for assessing the risk of femoral head AVN. We retrospectively reviewed 53 consecutive patients who underwent bone SPECT/CT within 2 weeks of internal fixation of a femoral neck fracture and follow-up serial hip radiographs over at least 12 months. Nine patients developed femoral head AVN. In 15 patients who showed normal uptake on immediate postoperative SPECT/CT, no AVN occurred, whereas 9 of 38 patients who showed cold defects of the femoral head later developed AVN. The negative predictive value of immediate postoperative SPECT/CT for AVN was 100 %, whereas the positive predictive value was 24 %. Among 38 patients with cold defects, 1 developed AVN 3 months postoperatively. A follow-up bone SPECT/CT was performed in the other 37 patients at 2–10 months postoperatively. The follow-up bone SPECT/CT revealed completely normalized femoral head uptake in 27, partially normalized uptake in 8, and persistent cold defects in 2 patients. AVN developed in 3.7 % (1/27), 62.5 % (5/8), and 100 % (2/2) of each group, respectively. According to the time point of imaging, radiotracer uptake patterns of the femoral head on postoperative bone SPECT/CT indicate the risk of AVN after internal fixation of femoral neck fractures differently. Postoperative bone SPECT/CT may help orthopedic surgeons determine the appropriate follow-up of these patients.

    To explain the mechanism of benign postoperative dural enhancement, the author made experimental model of rabbit's subdual hematoma and performed magnetic resonance (MR) imaging with gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA). On plain T1-weighted images, infused blood or blood cells could not be detected immediately after surgery. On follow up plain T1-weighted images, the infused blood could be identified in only a case with 1 cc blood infusion. Marked dural enhancement could be seen immediately after surgery and continued three to fourteen days after 1 cc or 0.1 cc blood or 0.1 cc red blood cells infusion. To the contrary, no definite dural enhancement could be seen in the cases with plasma or saline infusion. Subdural red blood cells were required for dural enhancement immediately after surgery. Pathological findings revealed three types of reaction to infused blood: newly formed capillarization with fresh hemorrhage from the capillaries; subdural hematoma and no reaction. After vanishment of dural enhancement, pathological findings of the specimens were identical to that of normal dura. Dural enhancement may be induced by increased permeability of the dura associated with subdural hematoma and/or the extravasation of the contrast from newly formed capillaries. (author).

    2011-07-01

    Full Text Available Abstract Background Postoperative delirium can result in increased postoperative morbidity and mortality, major demand for postoperative care and higher hospital costs. Hypnotics serve to induce and maintain anaesthesia and to abolish patients' consciousness. Their persisting clinical action can delay postoperative cognitive recovery and favour postoperative delirium. Some evidence suggests that these unwanted effects vary according to each hypnotic's specific pharmacodynamic and pharmacokinetic characteristics and its interaction with the individual patient. We designed this study to evaluate postoperative delirium rate after general anaesthesia with various hypnotics in patients undergoing surgical procedures other than cardiac or brain surgery. We also aimed to test whether delayed postoperative cognitive recovery increases the risk of postoperative delirium. Methods/Design After local ethics committee approval, enrolled patients will be randomly assigned to one of three treatment groups. In all patients anaesthesia will be induced with propofol and fentanyl, and maintained with the anaesthetics desflurane, or sevoflurane, or propofol and the analgesic opioid fentanyl. The onset of postoperative delirium will be monitored with the Nursing Delirium Scale every three hours up to 72 hours post anaesthesia. Cognitive function will be evaluated with two cognitive test batteries (the Short Memory Orientation Memory Concentration Test and the Rancho Los Amigos Scale preoperatively, at baseline, and postoperatively at 20, 40 and 60 min after extubation. Statistical analysis will investigate differences in the hypnotics used to maintain anaesthesia and the odds ratios for postoperative delirium, the relation of early postoperative cognitive recovery and postoperative delirium rate. A subgroup analysis will be used to categorize patients according to demographic variables relevant to the risk of postoperative delirium (age, sex, body weight and to the

    Co-management and critical care outreach for high risk surgical patients have been proposed to decrease postoperative complications and mortality. We proposed that a clinical project with postoperative comanagement and critical care outreach, the Post Operative Surveillance Team: (POST), would be associated with decreased hospital length of stay. We conducted a retrospective before (control group) and after (POST group) audit of this hospital program. POST was staffed for four months in 2010 by two intensive care nurses and two senior registrars who conducted daily ward rounds for the first five postoperative days on high risk patients undergoing inpatient general or urological surgery. The primary endpoint was length of hospital stay and secondary endpoints were Medical Emergency Team (MET) calls, cardiac arrests and in-hospital mortality. There were 194 patients in the POST group and 1,185 in the control group. The length of stay in the POST group, median nine days (Inter-quartile range [IQR]: 5 to 17 days), was longer than the control group, median seven days (IQR: 4 to 13 days): difference two days longer (95.0% confidence interval [95.0% CI]: 1 to 3 days longer, P audit found that the POST service was not associated with reduced length of stay. Models of co-management, different to POST, or with different performance metrics, could be tested.

    This study evaluated the efficacy of adjuvant therapy with 3.7 GBq radioactive iodine (RAI) in patients with papillary thyroid carcinoma (PTC) of intermediate risk with higher risk features and determined the predictive value of postoperative nonstimulated thyroglobulin (Tg). This was a prospective study including 85 patients with PTC of intermediate risk and higher risk features: tumor greater than 1 cm and aggressive histological subtype or vascular invasion; and/or more than three positive lymph node (LN) or LN greater than 1.5 cm or showing macroscopic extracapsular extension; and/or a combination of tumor greater than 4 cm, microscopic extrathyroidal extension, aggressive histology, and LN metastases (cN1). After thyroidectomy, all patients had nonstimulated Tg of at least 0.3 ng/ml and ultrasonography showed no anomalies. When evaluated 12 months after RAI therapy, an excellent response to initial therapy was achieved in 61 patients (71.7%). Structural disease was detected in five patients (5.9%). During follow-up, 6/80 patients (7.5%) without structural disease 1 year after RAI developed relapse. In the last assessment, 80 patients (94.1%) had nonstimulated Tg less than 1 ng/ml and no evidence of structural disease. There was no case of death because of the tumor. Postoperative nonstimulated Tg was a predictive factor of the main outcome (structural disease 1 year after RAI or recurrence) and the best cut-off was 1.8 ng/ml (sensitivity: 72.7%, specificity: 83.4%, negative predictive value: 95.4%). In patients with PTC of intermediate risk with higher risk features treated with 3.7 GBq RAI, postoperative nonstimulated Tg up to 1.8 ng/ml was a predictor of low risk of structural disease 1 year after therapy or recurrence.

    This study sought to investigate the clinical outcome and the role of postoperative radiotherapy for patients with salivary duct carcinoma (SDC) who had undergone surgery and postoperative radiotherapy. We performed a retrospective analysis of 25 SDC patients treated between 1998 and 2011 with surgery and postoperative radiotherapy. The median prescribed dose was 60 Gy (range, 49.5-61.4 Gy). The clinical target volume (CTV) was defined as the tumor bed in four patients, the tumor bed and ipsilateral neck in 14 patients, and the tumor bed and bilateral neck in six patients. Local control (LC), disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method, and prognostic variables were analyzed with the log-rank test. The 5-year LC, DFS and OS were 67%, 45% and 47%, respectively. Disease recurrence was found in 12 patients: seven as local, four as regional and eight as distant failure. Perineural and lymphovascular invasion was a significant prognostic factor for LC (P=0.03). Local failure was common, and the presence of local recurrence significantly affected the OS (P<0.05). We conclude that surgery and postoperative radiotherapy is expected to decrease the risk of local failure and contribute to good prognoses for patients with SDC. It might be advisable to have the CTV include the cranial nerves involved and the corresponding parts of the skull base in cases of pathologically positive perineural invasion. (author)

    There are few publications related to postoperative morbidity in hepatic hydatidosis and these have mixed results. The aim of this study was to determine risk and protective factors of postoperative morbidity in patients operated on for hepatic hydatidosis. A comprehensive review was made of the evidence, based on systematic reviews, clinical analyses and observational studies, obtained from the Trip Database, BVS, SciELO, Cochrane Central Register of Controlled Trials, WoS, MEDLINE, EMBASE, SCOPUS, EBSCOhost, IBECS, ePORTUGUESe, LILACS and WHOLIS. 1,087 related articles were identified; 69 fulfilled the selection criteria (2 systematic reviews, 3 clinical trials and 64 observational studies). Age, history of previous surgery for hepatic hydatidosis, location in the hepatic center, existence of biliary communications and evolutionary complications of the cyst were identified as risk factors, and radical surgical techniques as protective factors. Risk and protective factors were identified; however, the studies are few and the quality moderate to low. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Shuichiro Kobayashi

    Full Text Available ABSTRACT Purpose: To determine the predictive factors for postoperative urinary incontinence (UI following holmium laser enucleation of the prostate (HoLEP during the initial learning period. Patients and Methods: We evaluated 127 patients with benign prostatic hyperplasia who underwent HoLEP between January 2011 and December 2013. We recorded clinical variables, including blood loss, serum prostate-specific antigen levels, and the presence or absence of UI. Blood loss was estimated as a decline in postoperative hemoglobin levels. The predictive factors for postoperative UI were determined using a multivariable logistic regression analysis. Results: Postoperative UI occurred in 31 patients (24.4%, but it cured in 29 patients (93.5% after a mean duration of 12 weeks. Enucleation time >100 min (p=0.043 and blood loss >2.5g/dL (p=0.032 were identified as significant and independent risk factors for postoperative UI. Conclusions: Longer enucleation time and increased blood loss were independent predictors of postoperative UI in patients who underwent HoLEP during the initial learning period. Surgeons in training should take care to perform speedy enucleation maneuver with hemostasis.

    The association between borderline personality disorder and the ultra high risk (UHR) for psychosis state is unclear. The following study aimed to investigate the type of attenuated psychotic symptoms and prevalence of borderline personality pathology in a sample of UHR young people. Additionally, the study aimed to explore whether borderline personality pathology influenced the transition rate to psychosis. Medical records from Orygen Youth Health between 2007 and 2009 were examined. There were 180 patients who met UHR criteria and were included for analysis. Most patients were females (62.8%) and age ranged from 15 to 24 years. A quarter (25.2%) of UHR patients endorsed items consistent with borderline personality pathology. UHR patients with borderline personality pathology experienced a range of attenuated psychotic symptoms and could not be statistically differentiated from UHR patients with less significant or without borderline personality pathology. Borderline personality pathology did not increase or decrease the risk of developing a psychotic disorder. The absence of depression was the only predictor of psychosis. Many UHR patients present with concurrent borderline personality features. The psychotic experiences reported by UHR patients with borderline personality features were not limited to paranoid ideation, supporting the idea that borderline personality disorder may include a wider range of psychotic symptoms than previously thought. It is further possible that the psychotic symptoms experienced in this group could also be indicative of an emerging psychotic disorder. © 2015 Wiley Publishing Asia Pty Ltd.

    Full Text Available The Ki-67 labelling index is significant for the management of breast cancer. However, the concordance of Ki-67 expression between preoperative biopsy and postoperative surgical specimens has not been well evaluated. This study aimed to find the correlation in Ki-67 expression between biopsy and surgical specimens and to determine the clinicopathological risk factors associated with discordant values.Ki-67 levels were immunohistochemically measured using paired biopsy and surgical specimens in 310 breast cancer patients between 2008 and 2013. ΔKi-67 was calculated by postoperative Ki-67 minus preoperative levels. The outliers of ΔKi-67 were defined as [lower quartile of ΔKi-67-1.5 × interquartile range (IQR] or (upper quartile + 1.5 × IQR and were evaluated according to clinicopathological parameters by logistic regression analysis.The median preoperative and postoperative Ki-67 levels were 10 (IQR, 15 and 10 (IQR, 25, respectively. Correlation of Ki-67 levels between the two specimens indicated a moderately positive relationship (coefficient = 0.676. Of 310 patients, 44 (14.2% showed outliers of ΔKi-67 (range, ≤-20 or ≥28. A significant association with poor prognostic factors was found among these patients. Multivariate analysis determined that significant risk factors for outliers of ΔKi-67 were tumor size >1 cm, negative progesterone receptor (PR expression, grade III cancer, and age ≤35 years. Among 171 patients with luminal human epidermal growth factor receptor 2-negative tumors, breast cancer subtype according to preoperative or postoperative Ki-67 levels discordantly changed in 46 (26.9% patients and a significant proportion of patients with discordant cases had ≥1 risk factor.Ki-67 expression showed a substantial concordance between biopsy and surgical specimens. Extremely discordant Ki-67 levels may be associated with aggressive tumor biology. In patients with luminal subtype disease, clinical application of Ki-67

    This study aimed at reviewing a contemporary series of patients who underwent robotic renal and adrenal surgery by a single surgeon at a tertiary referral academic medical center over a 6-year period, specifically focusing on the unique and serious complication of post-operative rhabdomyolysis of the dependent lower extremity. The cases of 315 consecutive patients who underwent robotic upper tract surgery over a 6-year period from August 2008 to June 2014 using a standardized patient positioning were reviewed and analyzed for patient characteristics and surgical variables that may be associated with the development of post-operative rhabdomyolysis. The incidence of post-operative rhabdomyolysis in our series was 3/315 (0.95%). All three affected patients had undergone robotic nephroureterectomy. Those patients who developed rhabdomyolysis had significantly higher mean Body Mass Index, Charlson Comorbidity Index, and median length of stay than those who did not. The mean OR time in the rhabdomyolysis group was noted to be 52 min longer than the non-rhabdomyolysis group, though this value did not reach statistical significance. Given the trends of increasing obesity in the United States and abroad as well as the continued rise in robotic upper tract urologic surgeries, urologists need to be increasingly vigilant for recognizing the risk factors and early treatment of the unique complication of post-operative rhabdomyolysis.

    Full Text Available 【Abstract】Objective: To evaluate the role of high risk factors in octogenarians and nonagenarians with hip trauma, which may lead to excessive mortality and morbi- dity postoperatively. Methods: Fifty-four octogenarians and nonagenarians patients were enrolled in the study, receiving surgical repair of hip fracture in our hospital from January 2006 to January 2010. High risk factors were recorded preoperatively in detail. Complications and survival state were followed up by telephone for 2 years postoperatively. All the data were analyzed by Chi-square test with SPSS 13.0. Results: Twenty-six males (48.1%, aged from 80 to 94 years with a mean age of 84.2 years, and twenty-eight females (51.9%, aged from 80 to 95 years with a mean age of 83.4 years, were presented in the cohort study. The hip traumas were caused by daily slight injuries (52 cases and car accidents (2 cases, respectively. Twenty-eight patients (51.9% with femoral neck fracture while 26 patients (48.1% with intertrochanteric fracture were diagnosed through an anterior-posterior pelvic radiophotograph. In this series, 39 patients (72.2% suffered from one or more comorbidities preoperatively. The morbidity was 48.1% and the major cause was urinary tract infection, while a significant difference was noted between females and males. The mortality was 20.4% with a predominant cause of acute renal failure. Conclusions: The gender should be considered as a critical high risk factor in octogenarians and nonagenarians with hip trauma postoperatively. Females are more likely to suffer complications postoperatively, which is especially obvious in senile patients over 80 years (P<0.05. Urinary tract infection is the most frequent complication after hip surgery, followed by low limb embolism and malnutrition. The mortality is dramatically greater in patients over 80 years old than those below, and major causes are acute renal failure, multiple organ dysfunction syndrome and mental

    Purpose: Adenocarcinoma of the prostate is the most common human cancer of internal organs. Radical surgery is regarded by many to be the treatment of choice for capsule confined disease. Since accurate preoperative assessment of tumor stage is difficult to define, many patients are subsequently found to have pathological stage C (T3) disease. These patients should be considered for adjuvant radiotherapy. Methods and Materials: A group of 201 PS C (T3) unselected patients, treated with radical prostatectomy and limited pelvic lymphadenectomy, received postoperative irradiation to the prostate bed. This radiotherapy was given between 42-90 days after surgery and consisted of a median dose of 48 Gy. Patient survival, disease free survival, time to clinical and chemical relapse and the incidence of local and systemic relapse were analyzed. The influence of multiple parameters on the treatment outcome including patient age, treatment period, clinical stage, pathological stage, Gleason's score, prostate specific antigen (PSA), radiotherapy techniques and radiation dose were examined using univariate and multivariate analysis. Follow-up ranged from 3 to 15 years, with a median of 5 years. Results: The overall 5- and 10-year actuarial survival was 92% and 83% (median > 10 years), respectively and the 5- and 10-year disease-free survival (clinical and PSA) was 67% and 53% (median > 10 years), respectively. A total of 61 (30%) patients had a recurrence, including 23 (11%) patients who had clinical and 38 (19%) who had PSA recurrence. Of the 23 patients with clinical recurrence, 10 (5%) had local recurrence, including two patients who had local and systemic recurrence. Pathological stage and Gleason's score were independently predictive of recurrence (each with p 25 ng/ml) was also an important independent factor predicting tumor recurrence, p = 0.05. All other investigated parameters were not significant in predicting tumor recurrence. This treatment program was very well

    Background Delirium is a profound neuropsychiatric disturbance precipitated by acute illness. Although dementia is the major risk factor this has typically been considered a binary quantity (i.e., cognitively impaired versus cognitively normal) with respect to delirium risk. We used humans and mice to address the hypothesis that the severity of underlying neurodegenerative changes and/or cognitive impairment progressively alters delirium risk. Methods Humans in a population-based longitudinal study, Vantaa 85+, were followed for incident delirium. Odds for reporting delirium at follow-up (outcome) were modeled using random-effects logistic regression, where prior cognitive impairment measured by Mini-Mental State Exam (MMSE) (exposure) was considered. To address whether underlying neurodegenerative pathology increased susceptibility to acute cognitive change, mice at three stages of neurodegenerative disease progression (ME7 model of neurodegeneration: controls, 12 weeks, and 16 weeks) were assessed for acute cognitive dysfunction upon systemic inflammation induced by bacterial lipopolysaccharide (LPS; 100 μg/kg). Synaptic and axonal correlates of susceptibility to acute dysfunction were assessed using immunohistochemistry. Results In the Vantaa cohort, 465 persons (88.4 ± 2.8 years) completed MMSE at baseline. For every MMSE point lost, risk of incident delirium increased by 5% (p = 0.02). LPS precipitated severe and fluctuating cognitive deficits in 16-week ME7 mice but lower incidence or no deficits in 12-week ME7 and controls, respectively. This was associated with progressive thalamic synaptic loss and axonal pathology. Conclusion A human population-based cohort with graded severity of existing cognitive impairment and a mouse model with progressing neurodegeneration both indicate that the risk of delirium increases with greater severity of pre-existing cognitive impairment and neuropathology.

    Full Text Available Risk-behaviors are a major contributor to the leading causes of morbidity among adolescents and young people; however, their association with pathological Internet use (PIU is relatively unexplored, particularly within the European context. The main objective of this study is to investigate the association between risk-behaviors and PIU in European adolescents. This cross-sectional study was conducted within the framework of the FP7 European Union project: Saving and Empowering Young Lives in Europe (SEYLE. Data on adolescents were collected from randomized schools within study sites across eleven European countries. PIU was measured using Young’s Diagnostic Questionnaire (YDQ. Risk-behaviors were assessed using questions procured from the Global School-Based Student Health Survey (GSHS. A total of 11,931 adolescents were included in the analyses: 43.4% male and 56.6% female (M/F: 5179/6752, with a mean age of 14.89 ± 0.87 years. Adolescents reporting poor sleeping habits and risk-taking actions showed the strongest associations with PIU, followed by tobacco use, poor nutrition and physical inactivity. Among adolescents in the PIU group, 89.9% were characterized as having multiple risk-behaviors. The significant association observed between PIU and risk-behaviors, combined with a high rate of co-occurrence, underlines the importance of considering PIU when screening, treating or preventing high-risk behaviors among adolescents.

    To study the rate of postoperative hypocalcemia following completion thyroidectomy (CT), in comparison with the hypocalcemia rate following total thyroidectomy (TT). A retrospective study, performed at the McGill University Thyroid Cancer Center, Montreal, Quebec, Canada, from 2007 to 2012. Medical records of adult patients undergoing CT and TT operated by a single surgeon were reviewed. Data were extracted for demographics, postoperative calcium levels, surgical logs, and final surgical pathology. Hypocalcemia was defined as corrected serum calcium level ≤ 1.90 mmol/L, with concurrent serum parathyroid hormone hypocalcemia. There were 68 CTs and 146 TTs. Transient hypocalcemia occurred in 1 of 68 (1.5%) and 18 of 146 (12.5%) patients in the CT and TT groups, respectively. The rate of hypocalcemia was significantly lower in the CT compared with the TT group (P = .02). In both groups, there were no cases of permanent hypocalcemia. The risk of transient of hypocalcemia in patients undergoing CT is significantly lower than the rate of hypocalcemia in patients undergoing TT. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    Problem and pathological gambling refers to subclinical and clinical levels of maladaptive gambling, respectively, and is associated with specific sociodemographic characteristics as well as a number of poor health outcomes. We examined such demographic, physical health, mental health, and health-related behaviors in a sample of 7045 low-risk gamblers and 244 problem/pathological gamblers. Participants completed the 2014 North Carolina Behavioral Risk Factor Surveillance System telephone survey. Using the National Opinion Research Center's Diagnostic Screen for Gambling Disorders-CLiP, participants were categorized as either "problem/pathological gamblers" or "low-risk gamblers." Problem/pathological gamblers were younger, more likely to be male, of ethnic minority status, unmarried, and of lower education than low-risk gamblers. No physical health variables differentiated the groups but problem/pathological gamblers reported experiencing significantly more adverse childhood experiences and engaging in significantly more tobacco and alcohol use compared to low-risk gamblers. Moreover, gender moderated relationships between gambling group and several of the alcohol use variables such that male problem/pathological gamblers exhibited greater alcohol use behavior than male low-risk gamblers but no such relationship was present in females. Overall, this study expands the current knowledgebase on disordered gambling and highlights the need to assess disordered gambling in public health samples. Clinical implications are discussed.

    Bariatric surgery patients are at high risk of perioperative respiratory adverse events. We hypothesized that the use of sugammadex to reverse neuromuscular blockade could improve postoperative respiratory outcomes. Prospective observational series of consecutive patients scheduled for laparoscopic bariatric surgery in whom neuromuscular blockade was reverted with sugammadex were compared with a historical matched cohort of patients reverted with neostigmines. The necessity of postoperative mechanical ventilation or pathological changes in postoperative chest X-ray were two of the comparisons done. We enrolled 160 patients in each group (Sugammadex - SG and Historical - HG). Two patients (mean, CI 95%), (1.25, 0.34-4.4) in the SG and five patients in the HG (mean, CI 95%), (3.13, 1.34-7.11) required mechanical ventilation immediately after surgery (p=0.38, chi-square test). Significantly less chest X-ray postoperative changes were observed in the SG: 11 patients (6.9%) versus 26 patients (16.3%) in the HG (Odds ratio OR, CI 95%) (0.36, 0.18-0.8). Requirement of mechanical ventilation is not associated to the reversal agent employed. Less pathological postoperative chest X-ray changes were found in the group of patients whose neuromuscular blockade was reverted with sugammadex.

    The rate of, and possible risk factors for, postoperative craniofacial infection is unclear. To investigate this problem, we reviewed 349 cases of craniofacial skeletal procedures performed from 1996 to 1999 at our institution. Infection rate was determined and correlated with the use of implants, operative site, and cause of deformity. The inclusion criteria consisted of all procedures requiring autologous or prosthetic implantation in craniofacial skeletal sites, as well as all procedures involving bone or cartilage resection, osteotomies, debridement, reduction and/or fixation. Procedures that did not involve bone or cartilage surgery were excluded. The criteria for diagnosis of infection included clinical confirmation and one or more of 1) intravenous or oral antibiotic treatment outside of the prophylactic surgical regimen; 2) surgical intervention for drainage, irrigation, and or debridement; and 3) microbiological confirmation. Among the 280 surgical cases that fit the inclusion criteria and had complete records, there were 23 cases of postoperative infection (8.2%). The most common site for postoperative infection was the mandible (infection rate = 16.7%). Multiple logistic regression analysis revealed gunshot wound to be the most significant predictor of postoperative infection. Additionally, porous polyethylene implantation through a transoral route was correlated with a significant risk of postoperative infection.

    BACKGROUND: A relationship between patients with a genetic predisposition to and those who develop postoperative delirium has not been yet determined. The aim of this study was to determine whether there is an association between apolipoprotein E epsilon 4 allele (APOE4) and delirium after major surgery. METHODS: Of 230 intensive care patients admitted to the post anesthesia care unit (PACU) over a period of 3 months, 173 were enrolled in the study. Patients' demographics and intra- and postoperative data were collected. Patients were followed for the development of delirium using the Intensive Care Delirium Screening Checklist, and DNA was obtained at PACU admission to determine apolipoprotein E genotype. RESULTS: Fifteen percent of patients developed delirium after surgery. Twenty-four patients had one copy of APOE4. The presence of APOE4 was not associated with an increased risk of early postoperative delirium (4% vs. 17%; P = 0.088). The presence of APOE4 was not associated with differences in any studied variables. Multivariate analysis identified age [odds ratio (OR) 9.3, 95% confidence interval (CI) 2.0-43.0, P = 0.004 for age ≥65 years), congestive heart disease (OR 6.2, 95% CI 2.0-19.3, P = 0.002), and emergency surgery (OR 59.7, 95% CI 6.7-530.5, P < 0.001) as independent predictors for development of delirium. The Simplified Acute Physiology Score II (SAPS II) and The Acute Physiology and Chronic Health Evaluation II (APACHE II) were significantly higher in patients with delirium (P < 0.001 and 0.008, respectively). Hospital mortality rates of these patients was higher and they had a longer median PACU stay. CONCLUSIONS: Apolipoprotein e4 carrier status was not associated with an increased risk for early postoperative delirium. Age, congestive heart failure, and emergency surgery were independent risk factors for the development of delirium after major surgery.

    Retrospective case-control study. The purpose of this study was to examine the factors of postoperative paralysis in patients who have undergone thoracic ossification of posterior longitudinal ligament (OPLL) surgery. A higher percentage of thoracic OPLL patients experience postoperative aggravation of paralysis than cervical OPLL patients, including patients that presented great difficulties in treatment. However, there were a few reports to prevent paralysis thoracic OPLL. The 156 patients who had received thoracic OPLL surgery were selected as the subjects of this study. The items for review were the duration of disease; the preoperative muscle strength (Muscle Manual Testing); OPLL levels (T1/2-4/5: high, T5/6-8/9: middle, and T9/10-11/12: low); the spinal canal occupancy ratio; the ratio of yellow ligament ossification as a complication; the ratio of transcranial-motor evoked potential (Tc-MEP) derivation; the preoperative/postoperative kyphotic angles in the thoracic vertebrae; the correction angle of kyphosis; the duration of surgery; and the amount of bleeding. The subjects were divided into two groups based on the absence or presence of postoperative paralysis to determine the factors of postoperative paralysis. Twenty-three patients (14.7%) exhibited postoperative paralysis. Multivariate analysis identified factors associated with postoperative paralysis: the duration of disease (odds ratio, OR = 3.3); the correction angle of kyphosis (OR = 2.4); and the ratio of Tc-MEP derivation (OR = 2.2). The risk factors of postoperative paralysis are a short duration of disease and a small correction angle of kyphosis. In addition, ratios of Tc-MEP derivation below 50% may anticipate paralysis. 4.

    Objective: To investigate the clinical value of 99 Tc m -ethylenedicysteine (EC) diuretic renography (DR) in pre-and post-operative pediatric congenital hydronephrosis. Methods: The DR with injection of Furosemide at 15 min of forty children with hydronephrosis was retrospectively studied. The preoperative renal blood perfusion rate (BPR), effective renal plasma flow (ERPF), grade of hydronephrosis,renogram and renal dynamic imaging of pre- and post-operative kidneys were compared. The t-test and Mann-Whitney test were used for data analysis. Results: (1) Of 40 pathological kidneys, the BPR increased 5.99% (t=-5.13, P<0.01) from pre-operative to post-operative: (34.05 ± 11.07)% to (40.04 ± 8.56)%. The ERPF increased 12.48 ml/min (t=-4.35, P<0.01) from pre-operative to post-operative: (57.81 ± 34.32) ml/min to (70.29 ± 5.37) ml/min. (2) The grade of hydronephrosis of 40 pathological kidneys improved significantly(Z=-2.64, P<0.01) with the mean sum of ranks of 47.21 pre-operatively to 33.79 post-operatively.(3) As the hydronephrosis worsened, the collecting system became bigger, the renal parenchyma became thinner, the extent of intrarenal parenchymal photopenia became larger and the response to diuretic challenge in pathological kidneys decreased or became totally irresponsive. (4)Thirty-seven cases of obstruction at ureteropelvic junction (UPJO) and 3 cases at ureterovesical junction (UVJO) were diagnosed by DR, which were all confirmed by surgery. Conclusions: DR is a reliable method to evaluate pediatric congenital hydronephrosis.It can accurately reflect the grade and (or) severity of the disease, guide therapy and assess the therapeutic success of operation.

    The obesity epidemic is associated with a rise in coronary surgeries because obesity is a risk factor for coronary artery disease. Bariatric surgery is linked to improvement in cardiovascular co-morbidities and left ventricular function. No studies have investigated survival advantage in postoperative bariatric patients after coronary surgery. To determine if there is a benefit after coronary surgery in patients who have previously undergone bariatric surgery. National Inpatient Sample. We performed a retrospective, cross-sectional analysis of the National Inpatient Sample database from 2003 to 2010. We selected bariatric surgical patients who later underwent coronary surgery (n = 257). A comparison of postoperative complications and mortality after coronary surgery were compared with controls (n = 1442) using χ 2 tests, linear regression analysis, and multivariate logistical regression models. A subset population was identified as having undergone coronary surgery (n = 1699); of this population, 257 patients had previously undergone bariatric surgery. They were compared with 1442 controls. The majority was male (67.2%), white (82.6%), and treated in an urban environment (96.8%). Patients with bariatric surgery assumed the risk of postoperative complications after coronary surgery that was associated with their new body mass index (BMI) (BMI999.9, 95% CI .18 to>999.9, P = .07). Length of stay was significantly longer in postbariatric patients (BMIbariatric patients have a return to baseline risk of morbidity and mortality after coronary surgery.

    Approximately one in every two patients with pharmacoresistant temporal lobe epilepsy will not be rendered completely seizure-free after temporal lobe surgery. The reasons for this are unknown and are likely to be multifactorial. Quantitative volumetric magnetic resonance imaging techniques have provided limited insight into the causes of persistent postoperative seizures in patients with temporal lobe epilepsy. The relationship between postoperative outcome and preoperative pathology of white matter tracts, which constitute crucial components of epileptogenic networks, is unknown. We investigated regional tissue characteristics of preoperative temporal lobe white matter tracts known to be important in the generation and propagation of temporal lobe seizures in temporal lobe epilepsy, using diffusion tensor imaging and automated fibre quantification. We studied 43 patients with mesial temporal lobe epilepsy associated with hippocampal sclerosis and 44 healthy controls. Patients underwent preoperative imaging, amygdalohippocampectomy and postoperative assessment using the International League Against Epilepsy seizure outcome scale. From preoperative imaging, the fimbria-fornix, parahippocampal white matter bundle and uncinate fasciculus were reconstructed, and scalar diffusion metrics were calculated along the length of each tract. Altogether, 51.2% of patients were rendered completely seizure-free and 48.8% continued to experience postoperative seizure symptoms. Relative to controls, both patient groups exhibited strong and significant diffusion abnormalities along the length of the uncinate bilaterally, the ipsilateral parahippocampal white matter bundle, and the ipsilateral fimbria-fornix in regions located within the medial temporal lobe. However, only patients with persistent postoperative seizures showed evidence of significant pathology of tract sections located in the ipsilateral dorsal fornix and in the contralateral parahippocampal white matter bundle

    A group of pathological gamblers and a group of problem gamblers (i.e., gamblers at risk of becoming pathological) were compared to healthy controls on their risk-taking propensity after prior losses. Each participant played both the Balloon Analogue Risk Taking task (BART) and a modified version of the same task, where individuals face five repeated predetermined early losses at the onset of the game. No significant difference in risk-taking was found between groups on the standard BART task, while significant differences emerged when comparing behaviors in the two tasks: both pathological gamblers and controls reduced their risk-taking tendency after prior losses in the modified BART compared to the standard BART, whereas problem gamblers showed no reduction in risk-taking after prior losses. We interpret these results as a sign of a reduced sensitivity to negative feedback in problem gamblers which might contribute to explain their loss-chasing tendency.

    The conventional surgical treatment for patients with potentially curable transmural and/or node positive rectal cancer is a low anterior resection or abdominoperineal resection. Recently, there has been increasing interest in the use of local excision and postoperative radiation therapy as primary therapy for selected rectal cancers. The limited data suggest that the approach of local excision and postoperative radiation therapy should be limited to patients with either T 1 tumours with adverse pathological factors or T 2 tumours. Transmural tumours, which have a 24% local failure rate, are treated more effectively with standard surgery and pre- or postoperative therapy. The results of local excision and postoperative radiation therapy are encouraging, but more experience is needed to determine if this approach ultimately has similar local control and survival rates as standard surgery.

    Recent reports have suggested that caudal anesthesia may be associated with an increased risk of postoperative surgical complications. We examined our experience with caudal anesthesia in hypospadias repair to evaluate for increased risk of urethrocutaneous fistula or glanular dehiscence. All hypospadias repairs performed by a single surgeon in 2001-2014 were reviewed. Staged or revision surgeries were excluded. Patient age, weight, hypospadias severity, surgery duration, month and year of surgery, caudal anesthesia use, and postoperative complications were recorded. Bivariate and multivariate statistical analyses were performed. We identified 395 single-stage primary hypospadias repairs. Mean age was 15.6 months; 326 patients had distal (83%) and 69 had proximal (17%) hypospadias. Caudal anesthetics were used in 230 (58%) cases; 165 patients (42%) underwent local penile block at the discretion of the surgeon and/or anesthesiologist. Complications of urethrocutaneous fistula or glanular deshiscence occurred in 22 patients (5.6%) and were associated with caudal anesthetic use (OR 16.5, 95% CI 2.2-123.8, P = 0.007), proximal hypospadias (OR 8.2, 95% CI 3.3-20.0, P anesthesia was associated with an over 13-fold increase in the odds of developing postoperative surgical complications in boys undergoing hypospadias repair even after adjusting for urethral meatus location. Until further investigation occurs, clinicians should carefully consider the use of caudal anesthesia for children undergoing hypospadias repair. © 2017 John Wiley & Sons Ltd.

    Malignant struma ovarii is an extremely rare ovarian tumour containing malignant thyroid carcinoma within differentiated thyroid tissue, as the predominant tissue type. Surgery for suspected ovarian tumour and incidental pathological diagnosis is the most common presentation. Evidence supporting any particular approach to the clinical management of this condition is limited, mainly consisting of case reports, small series or pathological case series. There is no randomised evidence for postoperative management in view of the rarity of this condition. The opinion is divided between conservative management versus total thyroidectomy and radio-iodine ablation. We carried out a retrospective review of our series with focus on postoperative management of this rare condition. A review of existing literature was also carried out. Six patients with a median age of 52 years presented with various symptoms of abdominal pain, pressure or menstrual problems. After the initial gynaecological resection and specialised pathology review, they were subsequently treated with total thyroidectomy and administration of radioactive iodine. All of these six patients are in remission at a median follow up of 60 months. We favour aggressive postoperative management with total thyroidectomy and radioactive iodine, and long-term follow up of these patients.

    Magnetic resonance (MR) imaging has emerged as an important noninvasive diagnostic imaging technique for assessment of foot pathology. This modality, owing to its multiplanar imaging capability and inherent superiority in contrast, has been shown to be more accurate and sensitive for detection of plantar fascia pathology than any other imaging method. One of the most important and recognizable causes of heel pain is plantar fasciitis. With the exception of plantar fasciitis, there has been little emphasis on imaging other conditions that affect this important structure. The objective of this review is to demonstrate, from a perspective of MR imaging, the many different pathologic conditions that affect the plantar fascia. Included in this review will be a discussion of normal anatomy as well as entities such as acute plantar fasciitis, chronic plantar fasciitis, traumatic rupture, normal post-surgical changes, pathologic post-fasciotomy conditions, infection, and fibromatosis.

    To identify (1) the predominant level of evidence of the clinical studies regarding the hip pathology, risk factors, treatment, and clinical outcomes in artistic athletes (dancers, figure skaters, and gymnasts) (2) the most commonly reported hip pathology, risk factors, treatments, and clinical outcomes in dancers, figure skaters, and gymnasts. To conduct this systematic review PubMed, EMBASE, and Scopus databases were searched for relevant studies and pertinent data were collected from the eligible articles. Included were studies which reported hip injuries in artistic athletes, the risk factors, treatment, and/or the clinical outcomes. We excluded case reports or irrelevant studies. No meta-analysis was performed because of study heterogeneity. The methodical index for nonrandomized studies (MINORS) criteria were used for quality control. Thirty-eight studies were included in the analysis. The mean MINORS score was 13.6 ± 4.6 points indicating fair quality of evidence of the included articles. The predominant level of evidence was level IV. Chondrolabral pathology and muscle injuries were the most commonly reported pathologies. We found only 2 risk factor analysis studies; however, many studies reported risk correlation between artistic sports or imaging findings and hip pathology. Treatment strategies were reported in only 7 studies, clinical outcomes are significantly underreported. Chondrolabral pathology was the most commonly reported hip pathology in artistic athletes, however, prospective cohort studies are necessary to really understand these injuries and their associated risk factors. The lack of clinical outcomes is significant and future data collection is required to assess the effectiveness of the various treatments.

    Health care workers are experiencing increasing numbers of occupational illnesses. Safety practices in anatomical pathology laboratories (APL) are crucial to prevent unnecessary exposures to both chemical and biological agents. The main goal of this study was to determine if pathologists perceptions and actual practice mirror regulatory guidelines. Current available recommendations for APL were reviewed and used to construct an online survey distributed to pathologists. The survey was completed by 121 participants. Eighty-seven (72 %) of respondents reported receiving inadequate safety training. Most pathologists (82 %) were not well-informed about biosafety practices. Sixty-three (52 %) participants felt that the risks of chemical and infectious disease exposures in the APL were low. Most respondents reported having a needle stick or cut (71 %). Eighty-six (71 %) of participants reported musculo skeletal problems. This study indicated that there is a need for improving training in anatomical pathology safety practices in Mexican laboratories as daily practices do not reflected current guidelines.

    Intravenous thrombolysis and intra-arterial thrombectomy are now the standard therapies for patients with acute ischemic stroke. In-house strokes have often been overlooked even at stroke centers and there is no consensus on how they should be managed. Perioperative stroke happens rather frequently but treatment protocol is lacking, In China, the issue of in-house strokes has not been explored. The aim of this study is to explore the current management of in-house stroke and identify the common risk factors associated with perioperative strokes. Altogether, 51,841 patients were admitted to a tertiary hospital in Shanghai and the records of those who had a neurological consult for stroke were reviewed. Their demographics, clinical characteristics, in-hospital complications and operations, and management plans were prospectively studied. Routine laboratory test results and risk factors of these patients were analyzed by multiple logistic regression model. From January 1, 2015, to December 31, 2015, over 1800 patients had neurological consultations. Among these patients, 37 had an in-house stroke and 20 had more severe stroke during the postoperative period. Compared to in-house stroke patients without a procedure or operation, leukocytosis and elevated fasting glucose levels were more common in perioperative strokes. In multiple logistic regression model, perioperative strokes were more likely related to large vessel occlusion. Patients with perioperative strokes had different risk factors and severity from other in-house strokes. For these patients, obtaining a neurological consultation prior to surgery may be appropriate in order to evaluate the risk of perioperative stroke. Copyright © 2017. Published by Elsevier Inc.

In recent years, there has been focus on identifying risk factors predicting patients with high postoperative pain intensity or consumption of analgesics, which may facilitate...... thresholds were measured using electrical (single and 5 repeated) and pressure pain stimulation over the flank bilaterally (stone-side = operation side and control-side = non-operation side). Postoperative pain scores were recorded on a numerical rating scale and analgesic consumption was registered....... The responses to repeated electrical stimuli (temporal summation) were preoperatively increased on the stone-side compared to the control-side (P = 0.016). Preoperative electrical pain thresholds from the control-side correlated inversely with postoperative opioid consumption (single stimuli: ρ = -0.43, P

    STOP-BANG score (snore; tired; observed apnea; arterial pressure; body mass index; age; neck circumference and gender) can predict the risk of a patient having Obstructive Syndrome Apnea (OSA). The aim of this study was to evaluate the incidence STOP-BANG score≥3, in surgical patients admitted to the Post-Anesthesia Care Unit (PACU). Observational, prospective study conducted in a post-anesthesia care unit (PACU) during three weeks (2011). The study population consisted of adult patients after noncardiac and non-neurological surgery. Patients were classified as high risk of OSA (HR-OSA) if STOP-BANG score≥3 and Low-risk of OSA (LR-OSA) if STOP-BANG score<3 (LR-OSA). Patient demographics, intraoperative and postoperative data were collected. Patient characteristics were compared using Mann-Whitney U-test, t-test for independent groups, and chi-square or Fisher's exact test. A total of 357 patients were admitted to PACU; 340 met the inclusion criteria. 179 (52%) were considered HR-OSA. These patients were older, more likely to be masculine, had higher BMI, higher ASA physical status, higher incidence of ischemic heart disease, heart failure, hypertension, dyslipidemia and underwent more frequently insulin treatment for diabetes. These patients had more frequently mild/moderated hypoxia in the PACU (9% vs. 3%, p=0.012) and had a higher incidence of residual neuromuscular blockade (NMB) (20% vs. 16%, p=0.035). Patients with HR-OSA had a longer hospital stay. Patients with HR-OSA had an important incidence among patients scheduled for surgery in our hospital. These patients had more co-morbidities and were more prone to post-operative complications. Copyright © 2012 Sociedade Portuguesa de Pneumologia. Published by Elsevier España. All rights reserved.

    To evaluate the results and prognostic factors for postoperative adjuvant radiation therapy in patients at stages I and II of endometrial cancer. Materials and Methods: Between January 1991 and December 2006, 35 patients with FIGO stages I and II disease, who received adjuvant radiation therapy following surgery for endometrial cancer at Ewha Womans University Hospital, were enrolled in this study. A total of 17 patients received postoperative pelvic external beam radiation therapy; whereas, 12 patients received vaginal brachytherapy alone, and 6 patients received both pelvic radiation therapy and vaginal brachytherapy. Results: The median follow-up period for all patients was 54 months. The 5-yr overall survival and disease-free survival rates for all patients were 91.4% and 81.7%, respectively. The 5-yr overall survival rates for low-risk, intermediate-risk, and high-risk groups were 100%, 100% and 55.6%, respectively. In addition, the 5-yr disease-free survival rates were 100%, 70.0%, and 45.7%, respectively. Although no locoregional relapses were identified, distant metastases were observed in 5 patients (14%). The most common site of distant metastases was the lung, followed by bone, liver, adrenal gland, and peritoneum. A univariate analysis revealed a significant correlation between distant metastases and risk-group (p=0.018), pathology type (p=0.001), and grade (p=0.019). A multivariate analysis also revealed that distant metastases were correlated with pathology type (p=0.009). Papillary, serous and clear cell carcinoma cases demonstrated a poor patient survival rate compared to cases of endometrioid adenocarcinoma or adenosquamous carcinoma. The most common complication of pelvic external beam radiation therapy was enteritis (30%), followed by proctitis, leucopenia, and lymphedema. All these complications were of RTOG grades 1 and 2; no grades 3 and 4 were observed. Conclusion: For the low-risk and intermediate-risk groups (stages 1 and 2) endometrial

    To compare the operative outcome, morbidity profile, and functional outcome after transperitoneal laparoscopic dismembered pyeloplasty for ureteropelvic junction obstruction in unusual circumstances (intrinsic pathology in anomalous kidneys or unusual extrinsic pathologies; group 1) to the outcome after this procedure in familiar pathologies (normally located kidneys with intrinsic dysfunctional segment or extrinsic compression due to a crossing vessel; group 2). The patients were evaluated in detail. All patients underwent transperitoneal laparoscopic dismembered pyeloplasty. The operative and postoperative parameters were recorded. Patients were followed up after the procedure on a 3-month protocol. Imaging was repeated at 1 year. No intervention during the follow-up period (ie, nephrostomy, ureteral stenting, or redo pyeloplasty) and improvement in the hydronephrosis grade and diuretic renogram parameters was interpreted as procedural success. The operative, postoperative, and follow-up parameters in the 2 groups were compared. Group 1 included 17 patients with intrinsic pathologic features and renal anomalies with ureteropelvic junction obstruction due to unusual extrinsic pathology. All procedures were successfully completed with the laparoscopic approach. A significant difference was noted in the mean operative duration (group 1, 196.9 ± 10.3 minutes; group 2, 125.44 minutes, P = .00). The other operative and postoperative parameters were comparable. No significant operative or postoperative events were noted. A total of 14 patients (group 1) completed the 1-year follow-up protocol. The success rate was 92.9% (13 of 14) in group 1 and 97.9% (44 of 45) in group 2 (P = .42). The procedural duration for laparoscopic dismembered pyeloplasty in unusual circumstances is longer than in familiar pathologies. However, the morbidity profile and functional outcome in these 2 scenarios were comparable. Copyright © 2012 Elsevier Inc. All rights reserved.

    Two instruments for assessing patients' risk of postoperative nausea and vomiting (PONV) were compared. The existing protocol (protocol 1) assessed PONV risk using 16 weighted risk factors and was used for both adults and pediatric patients. The new protocol (protocol 2) included a form for adults and a pediatric-specific form. The form for adults utilized the simplified risk score, calculated using a validated, nonweighted, 4-point scale, and categorized patients' risk of PONV as low, moderate, or high. The form for pediatric patients used a 7-point, non-weighted scale and categorized patients' risk of PONV as moderate or high. A list was generated of all patients who had surgery during August 2005, for whom protocol 1 was used, and during April 2006, for whom protocol 2 was used. Fifty patients from each time period were randomly selected for data analysis. Data collected included the percentage of the form completed, the development of PONV, the number of PONV risk factors, patient demographics, and the appropriateness of prophylaxis. The mean +/- S.D. number of PONV risk factors was significantly lower in the group treated according to protocol 2 ( p = 0.001), but fewer patients in this group were categorized as low or moderate risk and more patients were identified as high risk (p < 0.001). More patients assessed by protocol 2 received fewer interventions than recommended (p < 0.001); however, the frequency of PONV did not significantly differ between groups. Implementation of a validated and simplified PONV risk-assessment tool appeared to improve form completion rates and appropriate risk assessment; however, the rates of PONV remained similar and fewer patients received appropriate prophylaxis compared with patients assessed by the existing risk-assessment tool.

    There is dilemma as to whether patients infected with the Human Immunodeficiency Virus (HIV) requiring implant orthopaedic surgery are at an increased risk for post-operative surgical site infection (SSI). We conducted a systematic review to determine the effect of HIV on the risk of post-operative SSI and sought to determine if this risk is altered by antibiotic use beyond 24 hours. We searched electronic databases, manually searched citations from relevant articles, and reviewed conference proceedings. The risk of postoperative SSI was pooled using Mantel-Haenszel method. We identified 18 cohort studies with 16 mainly small studies, addressing the subject. The pooled risk ratio of infection in the HIV patients when compared to non-HIV patients was 1.8 (95% Confidence Interval [CI] 1.3-2.4), in studies in Africa this was 2.3 (95% CI 1.5-3.5). In a sensitivity analysis the risk ratio was reduced to 1.4 (95% CI 0.5-3.8). The risk ratio of infection in patients receiving prolonged antibiotics compared to patients receiving antibiotics for up to 24 hours was 0.7 (95% CI 0.1-4.2). The results may indicate an increased risk in HIV infected patients but these results are not robust and inconclusive after conducting the sensitivity analysis removing poor quality studies. There is need for larger good quality studies to provide conclusive evidence. To better develop surgical protocols, further studies should determine the effect of reduced CD4 counts, viral load suppression and prolonged antibiotics on the risk for infection.

    Postoperative nausea and vomiting (PONV) has a high incidence in children and requires prophylactic and therapeutic strategies. PONV can be reduced by the avoidance of nitrous oxide, volatile anesthetics, and the reduction of postoperative opioids. The use of dexamethasone, 5-HT3 antagonists, or droperidol alone is potent, but combinations are even more effective to reduce PONV. Droperidol has a Food and Drug Administration warning. Hence, dexamethasone and 5-HT3 antagonists should be preferred as prophylactic drugs. It is further reasonable to adapt PONV prophylaxis to different risk levels. Prolonged surgery time, inpatients, types of surgery (e.g. strabismus and ear-nose-throat surgery), and patients with PONV in history should be treated as high risk, whereas short procedures and outpatients are to be treated as low risk. Concluding from the existing guidelines and data on the handling of PONV in children at least 3 years, the following recommendations are given: outpatients undergoing small procedures should receive a single prophylaxis, outpatients at high risk a double prophylaxis, inpatients with surgery time of more than 30 min and use of postoperative opioids should get double prophylaxis, and inpatients receiving a high-risk surgical procedure or with other risk factors a triple prophylaxis (two drugs and total intravenous anesthesia). Dimenhydrinate can be used as a second choice, whereas droperidol and metoclopramide can only be recommended as rescue therapy.

    Background Postoperative atrial fibrillation (AF), a frequent complication following cardiac surgery, causes morbidity and prolongs hospitalization. Inotropic drugs are commonly used perioperatively to support ventricular function. This study tested the hypothesis that the use of inotropic drugs is associated with postoperative AF. Methods and Results We evaluated perioperative risk factors in 232 patients who underwent elective cardiac surgery. All patients were in sinus rhythm at surgery. Sixty-seven (28.9%) patients developed AF a mean of 2.9±2.1 days after surgery. Patients who developed AF stayed in the hospital longer (PMilrinone use was associated with an increased risk of postoperative AF (58.2% versus 26.1% in non-users, Pmilrinone use (odds ratio 4.86, 95% CI 2.31-10.25, Pmilrinone use (odds ratio 4.45, 95% CI 2.01-9.84, Pmilrinone use with postoperative AF. Conclusion Milrinone use is an independent risk factor for postoperative AF following elective cardiac surgery. PMID:18824641

    The effectiveness of cryotherapy on joint arthroplasty recovery remains controversial. This systematic review was conducted to assess the effectiveness of cryotherapy in patients after joint arthroplasty. Comprehensive literature searches of several databases including Cochrane Library (2013), MEDLINE (1950-2013), and Embase (1980-2013) were performed. We sought randomised controlled trials that compared the experimental group received any form of cryotherapy with any control group after joint arthroplasty. The main outcomes were postoperative blood loss, adverse events, and pain. Analyses were performed with Revman 5.0. Results were shown as mean differences (MD) and standard deviations or as risk difference and 95 % confidence intervals (CIs). Ten trials comprised 660 total knee arthroplastys and three trials comprised 122 total hip arthroplastys (THAs) met the inclusion criteria. Blood loss was significantly decreased by cryotherapy (MD = -109.68; 95 % CI -210.92 to -8.44; P = 0.03). Cryotherapy did not increase the risk of adverse effect (n.s.). Cryotherapy decreased pain at the second day of postoperative (MD = -1.32; 95 % CI -2.37 to -0.27; P = 0.0003), but did not decreased pain at the first and third day of postoperative (n.s.). Cryotherapy appears effective in these selected patients after joint arthroplasty. The benefits of cryotherapy on blood loss after joint arthroplasty were obvious. However, the subgroup analysis indicated that cryotherapy did not decreased blood loss after THA. Cryotherapy did not increase the risk of adverse effect. Cryotherapy decreased pain at the second day of postoperative, but did not decreased pain at the first and third day of postoperative. II.

    Surgical and medical procedures, mainly those associated with nerve injuries, may lead to chronic persistent pain. Currently, one cannot predict which patients undergoing such procedures are 'at risk' to develop chronic pain. We hypothesized that the endogenous analgesia system is key to determining the pattern of handling noxious events, and therefore testing diffuse noxious inhibitory control (DNIC) will predict susceptibility to develop chronic post-thoracotomy pain (CPTP). Pre-operative psychophysical tests, including DNIC assessment (pain reduction during exposure to another noxious stimulus at remote body area), were conducted in 62 patients, who were followed 29.0+/-16.9 weeks after thoracotomy. Logistic regression revealed that pre-operatively assessed DNIC efficiency and acute post-operative pain intensity were two independent predictors for CPTP. Efficient DNIC predicted lower risk of CPTP, with OR 0.52 (0.33-0.77 95% CI, p=0.0024), i.e., a 10-point numerical pain scale (NPS) reduction halves the chance to develop chronic pain. Higher acute pain intensity indicated OR of 1.80 (1.28-2.77, p=0.0024) predicting nearly a double chance to develop chronic pain for each 10-point increase. The other psychophysical measures, pain thresholds and supra-threshold pain magnitudes, did not predict CPTP. For prediction of acute post-operative pain intensity, DNIC efficiency was not found significant. Effectiveness of the endogenous analgesia system obtained at a pain-free state, therefore, seems to reflect the individual's ability to tackle noxious events, identifying patients 'at risk' to develop post-intervention chronic pain. Applying this diagnostic approach before procedures that might generate pain may allow individually tailored pain prevention and management, which may substantially reduce suffering.

    To evaluate the frequency of pneumothorax after laparoscopic surgery and to identify possible correlations to endometriosis. Retrospective review. Tokyo University Hospital between 2006 and 2013. Four patients among a total of 2814 patients with a postoperative pneumothorax. Laparoscopic surgery for gynecologic benign disease. The main outcome was the clinical frequency and characteristics of the patients with postoperative pneumothorax. We observed 4 (0.14%) cases of postoperative pneumothorax after laparoscopic surgery, all of whom were diagnosed with endometriomas and developed a right-sided pneumothorax. The incidence of postoperative pneumothorax in 1097 patients with endometriomas was 0.36%, which was significantly higher than those without endometriomas. The presence of endometrioma should be considered a risk factor for postoperative pneumothorax in gynecologic laparoscopic surgery. Copyright © 2015 AAGL. Published by Elsevier Inc.

    To investigate the relationship between prostate volume measured from preoperative imaging and adverse pathologic features at the time of radical prostatectomy and evaluate the potential effect of clinical stage on such relationship. In 1756 men who underwent preoperative magnetic resonance imaging and radical prostatectomy from 2000 to 2010, we examined associations of magnetic resonance imaging-measured prostate volume with pathologic outcomes using univariate logistic regression and with postoperative biochemical recurrence using Cox proportional hazards models. We also analyzed the effects of clinical stage on the relationship between prostate volume and adverse pathologic features via interaction analyses. In univariate analyses, smaller prostate volume was significantly associated with high pathologic Gleason score (P.05). The association between prostate volume and recurrence was significant in a multivariable analysis adjusting for postoperative variables (P=.031) but missed statistical significance in the preoperative model (P=.053). Addition of prostate volume did not change C-Indices (0.78 and 0.83) of either model. Although prostate size did not enhance the prediction of recurrence, it is associated with aggressiveness of prostate cancer. There is no evidence that this association differs depending on clinical stage. Prospective studies are warranted assessing the effect of initial method of detection on the relationship between volume and outcome. Copyright © 2014 Elsevier Inc. All rights reserved.

    The aim of this paper is to evaluate the efficacy of surgery for patients with oral cavity or oropharyngeal cancer, and is impact on the final results of treatment combined with postoperative radiotherapy. Furthermore, predictive and prognostic value of clinical and histopatological postoperative factors were analysed, and estimation of clinical applicability of modified scale for risk of postoperative local and/or nodal recurrence according to Peters was checked. Material includes 218 cases of the advanced oral cavity or oropharyngeal cancer. All data were subdivided into 4 groups depending on treatment strategy. For the analysis of the treatment efficacy (overall and disease-free survival) many predictive and prognostic factors have been considered. Despite of multivariate logistic regression analysis of these factors, the risk of local recurrence was related to the results of combined treatment based on the modified numerical risk scale adapted from Peters. The risk value is the sum of scores given to individual prognostic factors. Time interval between surgery and radiotherapy (TI) and overall treatment time (TTT) have been accounted for the analysis. Generally; optimal results were noted in the group B, where surgery has been combined with postoperative radiotherapy. In case of surgery combined with preoperative radiotherapy (group E) 5-year DFS was 30%, and in the case when radiotherapy was delayed and applied when recurrence after primary surgery has occurred, the 5-year DFS was not higher than 20%. Macro- and microscopic surgical radicalism has been found one of the most important and significant prognostic factors. For positive margins (m+) 5-year DFS significantly decreases to about 20%. Surgical macro- and microradicalism has an important impact (p = 0.013) on the incidence of distant metastases. The scoring system for the recurrence was based on Peters scale. The sum of the risk scores (TRRI+n) for individual prognostic factors allow to allocate

    Postoperative peritonitis is a pathologic condition with a sometime nuclear clinical occurrence and therefore with an uncertain timing for reoperation. Aim of this paper is to identify the type and frequency of the digestive and systemic symptoms in relation to the anatomo-pathologic peroperative picture. Between 1980 and 1996, 119 patients were reoperated for a postoperative peritonitis (PPO) in the Surgical Department of Modena University. PPO was due to a lesion situated above the mesocolon in 33 patients, from the small bowel in 18, postappendicectomy in 25 and from the colon in 40. The first operation (for benign disease in 66.4%, for malignancy in 33.6%) was performed in emergency in 47 cases (39.5%) and as elective surgery in 72 (60.5%). The global mortality was of 33.6% (40 patients). An attempt is made to identify, the earlier and the most important bioclinical parameters for a correct indication to surgery. Twenty symptoms have been identified that, with different frequency, are strictly related with the onset of a PPO (in average 5 symptoms were positive). A research of these parameters, each 4-6 hours, allow to identify a subclinical PPO. During the decisional timing, it is important to check these general and digestive symptoms, apparently not serious, in order to avoid the onset appearance of an abdominal tenderness or a multiorgan failure that make the prognosis more severe.

    The aim of this study was to assess the results of curative surgery with and without radiotherapy in patients with T 1-2 N 0-1 oral tongue squamous cell carcinoma (OSCC) and to evaluate survival and prognostic factors. Retrospective analysis of 86 patients with T 1-2 N 0-1 OSCC who received surgery between January 2000 and December 2006. Fourteen patients (16.3%) received postoperative radiotherapy (PORT). Patient characteristics, tumor characteristics, treatment modality, failure patterns, and survival rates were analyzed. The median follow-up was 45 months. The five-year overall survival (OS) and disease-free survival (DFS) rates were 80.8% and 80.2%, respectively. Higher tumor grade and invasion depth ≥ 0.5 cm were the significant prognostic factors affecting five-year OS and DFS (OS rate; 65% vs. 91%, p = 0.001 for grade; 66% vs. 92%, p = 0.01 for invasion depth: DFS rate; 69% vs. 88%, p = 0.005 for grade; 66% vs. 92%, p = 0.013 for invasion depth). In the risk group, there was no local failure in patients with postoperative radiotherapy. In T 1-2 N 0-1 OSCC, factors that affected prognosis after primary surgery were higher tumor grade and deep invasion depth over 0.5 cm. Postoperative radiotherapy should be considered in early oral tongue cancer patients with these high-risk pathologic features

    Conclusions: The risk factors of post-operative infection are multiple and likely synergistic. While pre-operative HbA1c level is not independently associated with risk of post-operative infection, there are scenarios and patient subgroups where pre-operative HbA1c is useful in predicting an increased risk of infectious complications in the post-operative period.

  1. Attenuation of postoperative adhesions using a modeled manual therapy.

    Full Text Available Postoperative adhesions are pathological attachments that develop between abdominopelvic structures following surgery. Considered unavoidable and ubiquitous, postoperative adhesions lead to bowel obstructions, infertility, pain, and reoperations. As such, they represent a substantial health care challenge. Despite over a century of research, no preventive treatment exists. We hypothesized that postoperative adhesions develop from a lack of movement of the abdominopelvic organs in the immediate postoperative period while rendered immobile by surgery and opiates, and tested whether manual therapy would prevent their development. In a modified rat cecal abrasion model, rats were allocated to receive treatment with manual therapy or not, and their resulting adhesions were quantified. We also characterized macrophage phenotype. In separate experiments we tested the safety of the treatment on a strictureplasty model, and also the efficacy of the treatment following adhesiolysis. We show that the treatment led to reduced frequency and size of cohesive adhesions, but not other types of adhesions, such as those involving intraperitoneal fatty structures. This effect was associated with a delay in the appearance of trophic macrophages. The treatment did not inhibit healing or induce undesirable complications following strictureplasty. Our results support that that maintained movements of damaged structures in the immediate postoperative period has potential to act as an effective preventive for attenuating cohesive postoperative adhesion development. Our findings lay the groundwork for further research, including mechanical and pharmacologic approaches to maintain movements during healing.

    Despite advances in postoperative pain management, the proportion of patients with moderate to severe postoperative pain is still ranging 20-80%. In this retrospective study, we investigated 1736 patients to determine the incidence of postoperative pain in need of intervention (PPINI)defined as numeric rating scale >4 at rest in the post anaesthesia care unit early after awakening from general anaesthesia, and to identify possible risk factors. The proportion of patients with PPINI was 28.5%. On multivariate analysis, younger age (OR=1.300 [1.007-1.678], p=0.044), female gender (OR=1.494 [1.138-1.962], p=0.004), obesity (OR=1.683 [1.226-2.310], p=0.001), use of nitrous oxide (OR=1.621 [1.110-2.366], p=0.012), longer duration of surgery (OR=1.165 [1.050-1.292], p=0.004), location of surgery (musculoskeletal OR=2.026 [1.326-3.095], p=0.001; intraabdominal OR=1.869 [1.148-3.043], p=0.012), and ASA-PS I-II (OR=1.519 [1.131-2.039], P=0.005) were identified as independent risk factors for PPINI. Patients with PPINI experienced significantly more PONV (10.3% vs. 6.2%, p=0.003), more psychomotor agitation (5.5% vs. 2.7%, p=0.004), needed more application of opioid in PACU (62.8% vs. 24.2%, p<0.001), stayed significantly longer in PACU (89.6min [70-120] vs. 80min [60-100], p<0.001), had a longer median length of hospital stay (6.6 days [4.0-8.8] vs. 6.0 days [3.2-7.8

    A De Garengeot's hernia is the very rare dual pathology of a vermiform appendix within a femoral hernia. We discuss the rare case of a 62 year old female who presented as an emergency with a strangulated femoral hernia. Within the hernia sac a partly necrotic vermiform appendix was discovered. The patient successfully underwent an appendicectomy and repair of her femoral hernia. The post-operative period was uneventful, with no further issues at follow-up. Our case report displays the successful treatment of a De Garengeot's hernia as an emergency admission, with a shorter than average admission time, and no post-operative complications. This is a rare case of dual pathology, of which we believe there are few published cases. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Individuals with pathological gambling have an increased risk for suicidal events. Additionally, the prevalence of comorbid psychiatric disorders is high among pathological gamblers. This study analyzes whether the type of gambling is associated with suicidal events in pathological gamblers independently from comorbidity. Participants were recruited in 4 different ways: via random telephone sample from the general population, via individual invitation for study participation in gambling locations, through various media and the distribution of a leaflet in various settings, and via inpatient treatment facilities for pathological gambling. The final sample included 442 participants with a lifetime diagnosis of pathological gambling. A standardized clinical interview was conducted. High financial losses were associated with suicidal events (odds ratio [OR] = 1.94, 95% 95% confidence interval [CI], [1.11, 3.37]), as were mood disorders (OR = 7.70, 95% CI, [4.44, 13.37]) and female gender (OR = 2.52, 95% CI, [1.20, 5.28]). Gambling on electronic gambling machines in gambling halls or bars was associated with increased odds of suicidal events (OR = 2.94, 95% CI, [1.38, 6.24]). Other types of gambling, such as casino games or betting on sports, or the number of DSM-IV criteria for pathological gambling were not associated independently with suicidal events. Our findings suggest that gambling on electronic gambling machines in gambling halls or bars is associated with suicidal events in pathological gamblers independently of comorbidity. This result shows that the type of gambling needs to be considered as a relevant factor in gambling research. (c) 2016 APA, all rights reserved).

    OBJECTIVE Postoperative cerebellar mutism syndrome (pCMS) occurs in 7%-50% of children after cerebellar tumor surgery. Typical features include a latent onset of 1-2 days after surgery, transient mutism, emotional lability, and a wide variety of motor and neurobehavioral abnormalities. Sequelae of this syndrome usually persist long term. The principal causal factor is bilateral surgical damage (regardless of tumor location) to any component of the proximal efferent cerebellar pathway, which leads to temporary dysfunction of cerebral cortical regions as a result of diaschisis. Tumor type, cerebellar midline location, and brainstem involvement are risk factors for pCMS that have been identified repeatedly, but they do not explain its latent onset. Ambiguous or negative results for other factors, such as hydrocephalus, postoperative meningitis, length of vermian incision, and tumor size, have been reached. The aim of this study was to identify perioperative clinical, radiological, and laboratory factors that also increase risk for the development of pCMS. The focus was on factors that might explain the delayed onset of pCMS and thus might provide a time window for taking precautionary measures to prevent pCMS or reduce its severity. The study was focused specifically on children who had undergone surgery for medulloblastoma. METHODS In this single-center retrospective cohort study, the authors included 71 children with medulloblastoma, 28 of whom developed pCMS after primary resection. Clinical and laboratory data were collected prospectively and analyzed systematically. Variables were included for univariate and multivariate analysis. RESULTS Univariate regression analysis revealed 7 variables that had a significant influence on pCMS onset, namely, tumor size, maximum tumor diameter > 5 cm, tumor infiltration or compression of the brainstem, significantly larger decreases in hemoglobin (p = 0.010) and hematocrit (p = 0.003) in the pCMS group after surgery than in the

    Surgical site infection (SSI) complicates approximately 2% of surgeries in the Veterans Affairs (VA) hospitals. Surgical site infections are responsible for increased morbidity, length of hospital stay, cost, and mortality. Surgical site infection can be minimized by modifying risk factors. In this study, we identified risk factors and developed accurate predictive surgical specialty-specific SSI risk prediction models for the Veterans Health Administration (VHA) surgery population. In a retrospective observation study, surgical patients who underwent surgery from October 2013 to September 2016 from 136 VA hospitals were included. The Veteran Affairs Surgical Quality Improvement Program (VASQIP) database was used for the pre-operative demographic and clinical characteristics, intra-operative characteristics, and 30-day post-operative outcomes. The study population represents 11 surgical specialties: neurosurgery, urology, podiatry, otolaryngology, general, orthopedic, plastic, thoracic, vascular, cardiac coronary artery bypass graft (CABG), and cardiac valve/other surgery. Multivariable logistic regression models were developed for the 30-day post-operative SSIs. Among 354,528 surgical procedures, 6,538 (1.8%) had SSIs within 30 days. Surgical site infection rates varied among surgical specialty (0.7%-3.0%). Surgical site infection rates were higher in emergency procedures, procedures with long operative duration, greater complexity, and higher relative value units. Other factors associated with increased SSI risk were high level of American Society of Anesthesiologists (ASA) classification (level 4 and 5), dyspnea, open wound/infection, wound classification, ascites, bleeding disorder, chemotherapy, smoking, history of severe chronic obstructive pulmonary disease (COPD), radiotherapy, steroid use for chronic conditions, and weight loss. Each surgical specialty had a distinct combination of risk factors. Accurate SSI risk-predictive surgery specialty

    NSQIP Risk Calculator was developed to allow surgeons to inform their patients about their individual risks for surgery. Its ability to predict complication rates and length of stay (LOS) has made it an appealing tool for both patients and surgeons. However, the NSQIP Risk Calculator has been criticized for its generality and lack of detail towards surgical subspecialties, including the hepatopancreaticobiliary (HPB) surgery. We wish to determine whether the NSQIP Risk Calculator is predictive of post-operative complications and LOS with respect to Whipple's resections for our patient population. As well, we wish to identify strategies to optimize early surgical outcomes in patients with pancreatic cancer. We conducted a retrospective review of patients who underwent elective Whipple's procedure for benign or malignant pancreatic head lesions at Health Sciences North (Sudbury, Ontario), a tertiary care center, from February 2014 to August 2016. Comparisons of LOS and post-operative complications between NSQIP-predicted and actual ones were carried out. NSQIP-predicted complications rates were obtained using the NSQIP Risk Calculator through pre-defined preoperative risk factors. Clinical outcomes examined, at 30 days post-operation, included pneumonia, cardiac events, surgical site infection (SSI), urinary tract infection (UTI), venous thromboembolism (VTE), renal failure, readmission, and reoperation for procedural complications. As well, mortality, disposition to nursing or rehabilitation facilities, and LOS were assessed. A total of 40 patients underwent Whipple's procedure at our center from February 2014 to August 2016. The average age was 68 (50-85), and there were 22 males and 18 females. The majority of patients had independent baseline functional status (39/40) with minimal pre-operative comorbidities. The overall post-operative morbidity was 47.5% (19/40). The rate of serious complication was 17.5% with four Clavien grade II, two grade III, and one grade

    Full Text Available Objective. To evaluate the incidence of accidental parathyroidectomy in our series of total thyroidectomies, to investigate its clinical and biochemical consequences, and to identify potential risk factors. Methods. Patients who underwent total thyroidectomy between January 2006 and December 2015 were retrospectively analyzed. Pathology reports were reviewed to identify those cases who had an incidental parathyroidectomy and these were compared to patients with no parathyroidectomy, in terms of clinical (age, sex, and symptoms of hypocalcemia, pathological (thyroid specimen weight, Hashimoto thyroiditis, and malignancy, and biochemical (serum calcium and phosphate levels factors. Results. 281 patients underwent total thyroidectomy during the study period. Incidental parathyroidectomy was noticed in 24.9% of cases, with 44.3% of parathyroid glands found in an intrathyroidal location. Evidence of postoperative biochemical hypocalcemia was noticed in 28.6% of patients with parathyroidectomy, compared with 13.3% in the no-parathyroidectomy group (p=0.003. Symptomatic hypocalcemia was observed in 5.7% and 3.8%, respectively (p=0.49. Age, sex, thyroid specimen weight, Hashimoto thyroiditis, and malignancy did not differ significantly between the two groups. Conclusions. Our study found an association of incidental parathyroidectomy with transient postoperative biochemical hypocalcemia, but not with clinically symptomatic disease. Age, sex, thyroid gland weight, Hashimoto thyroiditis, and malignancy were not identified as risk factors.

    Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are bariatric procedures with acceptable risk of postoperative morbidities and mortalities, but identification of high-risk patients is an ongoing issue. DeMaria et al. introduced the Obesity Surgery Mortality Risk Score (OS-MRS), which was designed for mortality risk assessment but not perioperative morbidity risk. To assess the possibility to use the OS-MRS to predict the risk of perioperative complications related to LSG and LRYGB. Retrospective analysis of patients operated on for morbid obesity was performed. Patients were evaluated before and after surgery. We included 408 patients (233 LSG, 175 LRYGB). Perioperative complications were defined as adverse effects in the 30-day period. The Clavien-Dindo scale was used for description of complications. Patients were assigned to five grades and three classes according to the OS-MRS results, then risk of morbidity was analyzed. Complications were observed in 30 (7.35%) patients. Similar morbidity was related to both procedures (OR = 1.14, 95% CI: 0.53-2.44, p = 0.744). The reoperation and mortality rates were 1.23% and 0.49% respectively. There were no significant differences in median OS-MRS value between the group without and the group with perioperative complications. There were no significant differences in OS-MRS between groups (p = 0.091). Obesity Surgery Mortality Risk Score was not related to Clavien-Dindo grades (p = 0.800). It appears that OS-MRS is not useful in predicting risk of perioperative morbidity after bariatric procedures.

    Unexpected deaths still occur following major surgical procedures. The cause is often unknown but may be cardiac or thromboembolic in nature. Postoperative ischaemia, infarction and sudden cardiac death may be triggered by episodic or constant arterial hypoxaemia, which increases during the night...... deaths occurred at night-time. These results suggest a need for further studies of sleep- and respiration-related effects on postoperative nocturnal cardiac function. The efficacy of monitoring during this apparent high-risk period should be evaluated....

    Regional lymph node metastases significantly influence the prognosis of patients with parotid cancer. To assess our indications of elective neck dissection and postoperative radiotherapy for parotid cancer, a retrospective chart review was performed. Between 2001 and 2009, 35 patients with parotid cancer were initially treated at our department. The median follow-up was 30 months (range, 10-90 months). Out of all patients, 31 (89%) patients were preoperatively diagnosed as malignant, while 4 (11%) patients were initially diagnosed as benign. Mucoepidermoid carcinoma was the most common histological type (10 patients). Twenty-two tumors (63%) were pathologically diagnosed as high-grade. The numbers of patients with Stages I, II, III, and IVA were 3, 10, 7, and 15, respectively. Ipsilateral neck dissection (Level II-V) was performed in seven patients with clinically positive neck metastasis (cN+), and in ten patients without lymph node metastasis who had T4 disease, high-grade malignancy, or positive neck (Level II) metastasis during intraoperative evaluation. Postoperative radiotherapy was performed in 24 patients with pathological T4, high-grade malignancy, positive surgical margin, multiple neck metastasis and/or extranodal extension (ENI). Seven of 28 (25%) patients with clinically N0 had pathologically positive neck metastasis (pN+). Regional recurrence developed in one patient with high-grade malignancy and ENI (T4N2b). Disease-specific survival rates for Stages I, II, III, and IVA at 3 years were 100%, 73%, 100%, and 37%, respectively. Loco-regional control rates for pN0 (21 patients) and pN+ (14 patients) at 3 years were 90% and 95%, respectively. Our present favorable loco-regional control supported our current indications of elective neck dissection and postoperative radiotherapy. We also recommend intraoperative biopsy of level IIB nodes to study the need for elective neck dissection. (author)

    The objectives of this study were to develop a risk-adjusted model to estimate individual postoperative costs after major lung resection and to use it for internal economic audit. Variable and fixed hospital costs were collected for 679 consecutive patients who underwent major lung resection from January 2000 through October 2006 at our unit. Several preoperative variables were used to develop a risk-adjusted econometric model from all patients operated on during the period 2000 through 2003 by a stepwise multiple regression analysis (validated by bootstrap). The model was then used to estimate the postoperative costs in the patients operated on during the 3 subsequent periods (years 2004, 2005, and 2006). Observed and predicted costs were then compared within each period by the Wilcoxon signed rank test. Multiple regression and bootstrap analysis yielded the following model predicting postoperative cost: 11,078 + 1340.3X (age > 70 years) + 1927.8X cardiac comorbidity - 95X ppoFEV1%. No differences between predicted and observed costs were noted in the first 2 periods analyzed (year 2004, $6188.40 vs $6241.40, P = .3; year 2005, $6308.60 vs $6483.60, P = .4), whereas in the most recent period (2006) observed costs were significantly lower than the predicted ones ($3457.30 vs $6162.70, P model may be used as a methodologic template for economic audit in our specialty and complement more traditional outcome measures in the assessment of performance.

    To investigate the patterns of locoregional recurrence of pathologic T3N0 (pT3N0) lower rectal cancer omitting postoperative radiotherapy (RT) and explore the potential of modification of a RT field. From Jan 2003 to Nov 2011, 35 patients omitting preoperative or postoperative RT for pT3N0 lower rectal cancer were included. We defined the lower rectal cancer as the tumor with the inferior margin located below the virtual line-a convergent level between rectal wall and levator ani muscle. All patients had radiologic examinations for recurrence evaluation during the follow-up duration. The median follow-up duration was 66.4 months (range, 1.4 to 126.1 months). Eight (22.9%) of the 35 patients had recurrence. Three (8.6%) was local recurrence (LR) only, 3 (8.6%) was distant metastasis (DM) only, and 2 (5.7%) was LR with DM. All LR were located at primary tumor sites. The overall survival rate, LR-free survival rate, and DM-free survival rate at 5 years was 79.8%, 83%, and 87%, respectively. All LR developed from tumors over 5 cm. However, there was no statistical significance (p = 0.065). There was no other risk factor for LR. Even though the patients included in this study had pathologically favorable pT3N0 rectal cancer, LR developed in 14.3% of patients. Most of the LR was located at primary tumor sites prior to surgery. Based on these findings, it might seem reasonable to consider postoperative RT with a smaller radiation field to the primary tumor site rather than the conventional whole pelvic irradiation.

    The long-term postoperative improvement of quality of life (QOL) and employment were investigated in patients undergoing resection of epileptogenic lesions detected by magnetic resonance (MR) imaging to identify the associated preoperative factors. Thirty of 47 patients who underwent lesionectomy between 1987-2001 replied to questionnaires. Patients with extratemporal resection outnumbered those with temporal lobe resection. The mean follow-up period was 12.4±3.7 years. An arbitrary score for quantitatively assessing QOL was assigned. The mean increases in QOL score points were significantly higher in the late childhood onset group than those in the early childhood onset group, and were also significantly higher in the temporal resection group and extratemporal resection of non-dysplastic cortical pathology group than in the extratemporal resection of dysplastic cortical pathology group. Postoperative QOL improvement and occupational status of patients depended on the completeness of seizure control. Resection of lesions detected by MR imaging in patients with intractable epilepsy resulted in effective long-term QOL improvement and postoperative occupational status. Favorable outcome was related mainly to the pathology of the epileptogenic lesions, whether the lesion site was temporal or extratemporal, and the completeness of seizure control. (author)

    The assessment of bone healing and loosening of endoprosthesis material was long the primary indication for postoperative projection radiography and CT imaging of the hip joint following trauma and endoprosthesis implantation. With the increasing number of joint-preserving surgery, e. g. of surgical hip luxation and hip arthroscopy for the treatment of femoroacetabular impingement (FAI), high-resolution imaging of intra-articular pathologies before and after surgery has become increasingly important. In this review article, diagnostic imaging of the hip joint is presented following common trauma surgery and orthopedic surgery interventions. The imaging modalities of projection radiography, CT and MRI including direct MR-arthrography are discussed with regard to their diagnostic capability in the postoperative assessment of the hip joint. Among others topics, imaging is discussed following hip arthroplasty, following surgical hip luxation and arthroscopic interventions for the treatment of FAI, as well as following core decompression for avascular necrosis of the femoral head. Moreover, orthopedic interventions of the hip joint in children and adolescents are presented and the dedicated reporting of postoperative imaging is outlined.

    Currently, there are only a few retrospective, single-institution studies that have addressed the prevalence and risk factors associated with unplanned admissions to the pediatric intensive care unit (ICU) after surgery. Based on the limited amount of studies, it appears that airway and respiratory complications put a child at increased risk for unplanned ICU admission. A more extensive and diverse analysis of unplanned postoperative admissions to the ICU is needed to address risk factors that have yet to be revealed by the current literature. To establish a rate of unplanned postoperative ICU admissions in pediatric patients using a large, multi-institution data set and to further characterize the associated risk factors. Data from the National Anesthesia Clinical Outcomes Registry were analyzed. We recorded the overall risk of unplanned postoperative ICU admission in patients younger than 18 years and performed univariate and multivariate logistic regression analysis to identify the associated patient, surgical, and anesthetic-related characteristics. Of the 324 818 cases analyzed, 211 reported an unexpected ICU admission. There was an increased likelihood of unplanned postoperative ICU in infants (age anesthesia were also associated with unplanned ICU admissions. This study establishes a rate of unplanned ICU admission following surgery in the heterogeneous pediatric population. This is the first study to utilize such a large data set encompassing a wide range of practice environments to identify risk factors leading to unplanned postoperative ICU admissions. Our study revealed that patient, surgical, and anesthetic complexity each contributed to an increased number of unplanned ICU admissions in the pediatric population.

Breast-related cancer antigen (BRCA) mutation carriers and BRCAX patients (those with a significant family history of breast and ovarian cancer). Minimally invasive risk-reduction surgery. Overall, 85 women underwent risk-reducing surgery: 30 (35%) and 55 (65%) had hysterectomy plus bilateral salpingo-oophorectomy (BSO) and BSO alone, respectively. Overall, in 6 (7%) patients, the final pathology revealed unexpected cancer: 3 early-stage ovarian/fallopian tube cancers, 2 advanced-stage ovarian cancers (stage IIIA and IIIB), and 1 serous endometrial carcinoma. Additionally, 3 (3.6%) patients had incidental finding of serous tubal intraepithelial carcinoma. Four (4.7%) postoperative complications within 30 days from surgery were registered, including fever (n = 3) and postoperative ileus (n = 1); no severe (grade 3 or more) complications were observed. All complications were managed conservatively. The presence of occult cancer was the only factor predicting the development of postoperative complications (p = .02). Minimally invasive risk-reducing surgery is a safe and effective strategy to manage BRCA mutation carriers. Patients should benefit from an appropriate counseling about the high prevalence of undiagnosed cancers observed at the time of surgery. Copyright © 2017 AAGL. Published by Elsevier Inc.

    Vascular groin wounds have higher than expected surgical site infection (SSI) rates and some patients are at enhanced risk. The Wiseman et al. paper suggests an objective scoring system that identifies patients at enhanced risk of postdischarge SSI. We hypothesize that prophylactic groin wound vacuum-assisted closure (VAC) therapy in enhanced risk patients will decrease SSI and readmission and the Wiseman model provides potential evidence that enhanced risk patients can be objectively identified. A single institution, retrospective analysis was conducted from January 2013 to September 2016 utilizing procedure codes to identify patients with wound VACs placed in the operating room. Two distinct groups were identified. The first was a wound complication patient group with 15 limbs (13 patients) with a groin wound VAC placed within 45 days postoperatively for groin wound complications. Eleven of these limbs had the VAC placed at readmission. The second group was a prophylactic patient group that included 8 limbs (7 patients) who received a VAC prophylactically placed in the enhanced risk wounds. These wounds were determined to be enhanced risk based on clinical criteria judged by the operating surgeon such as a large overhanging panniculus and/or one of several ongoing medical issues. We calculated a Wiseman score for all patients, determined total cost of the readmissions, and determined 30-day postsurgical SSI incidence for the prophylactic VAC group. Per the Wiseman scores, 9 limbs with postoperative complications were high risk and 3 limbs were moderate/high risk. Eleven limbs had a VAC placed at readmission with an average readmission cost of $8876.77. For the prophylactic group, 8 limbs were high risk with no observed postdischarge SSI in the first 30 days from surgery. The Wiseman scores showed close correlation between the retrospective high and moderate/high risk groups versus the prophylactic VAC group (31.5 ± 7.3 vs. 32 ± 5.5, P = 0.87). The Wiseman

    Introduction A De Garengeot’s hernia is the very rare dual pathology of a vermiform appendix within a femoral hernia. Presentation of case We discuss the rare case of a 62 year old female who presented as an emergency with a strangulated femoral hernia. Within the hernia sac a partly necrotic vermiform appendix was discovered. The patient successfully underwent an appendicectomy and repair of her femoral hernia. The post-operative period was uneventful, with no further issues at follow-up. Discussion Our case report displays the successful treatment of a De Garengeot's hernia as an emergency admission, with a shorter than average admission time, and no post-operative complications. Conclusion This is a rare case of dual pathology, of which we believe there are few published cases. PMID:26520035

    Coma is a state of profound unresponsiveness that can occur as a serious perioperative complication. The study of risk factors for, and sequelae of, postoperative coma has been limited due to the rarity of the event. To determine the incidence, risk factors and impact of postoperative coma in a large patient population. Observational study using a prospectively gathered national dataset. Data from 858 606 patients were analysed. The incidence of postoperative coma of more than 24-h duration was identified. Logistic regression was used to identify independent predictors and develop a risk model of postoperative coma in derivation and validation cohorts; 30-day mortality was also analysed. The incidence of postoperative coma was 0.06%. Multivariate analysis revealed the following independent predictors: liver disease, systemic sepsis, age at least 63 years, renal disease, emergency operation, cardiac disease, hypertension, prior neurological disease, diabetes mellitus and BMI 25 to 29.99 kg m (protective). These predictors were incorporated into a risk index classification; odds ratios for postoperative coma increased from 2.5 with one risk factor to 18.4 with three. Coma was associated with 74.2% all-cause mortality; coma associated with cardiac arrest had a 1.9-fold higher mortality. This is the largest study of postoperative coma ever reported and will be useful for determining risk of coma of more than 24 h duration when evaluating an unresponsive patient following surgery. Data on prognosis will aid medical and ethical decision-making for the comatose surgical patient.

    Pankova, V B; Preobrazhenskaya, E A; Fedina, I N

    The objective of the present study was to analyze the structure of concomitant somatic pathology in the subjects experiencing the occupational hearing problems. The study demonstrated the increase in the frequency of concomitant chronic diseases and the prevalence of polynosological conditions with the increasing severity of hearing impairment. It was shown that cardiovascular pathologies tend to enhance the risk of hearing loss in the employees engaged in «noisy» occupations. The cause-and-effect relationships were elucidated as the contribution of the "vascular" factor to the formation of occupational pathology of the organs of hearing. The clinical audilogical features of co-morbid occupational hearing impairment associated with vascular pathology were characterized by the accelerated development and progression of the hearing disorders with the gradual disappearance of the audiological signs characteristic of noise-induced lesions.

    The purpose of this study was to assess the incidence and risk factors associated with postoperative nausea (PON) and vomiting (POV) after orthognathic surgery. A review of the clinical records of consecutively enrolled subjects (2008–2012) at a single academic institution was conducted between 9/2013 and 3/2014. Data on the occurrence of PON and POV and potential patient-related, intraoperative, and postoperative explanatory factors were extracted from the medical records. Logistic models were used for the presence/absence of postoperative nausea and vomiting separately. Data from 204 subjects were analyzed: 63% were female, 72% Caucasian, and the median age was 19 years. Thirty-three percent had a mandibular osteotomy alone, 27% a maxillary osteotomy alone, and 40% had bimaxillary osteotomies. Sixty-seven percent experienced PON and 27% experienced POV. The most important risk factors for PON in this series were female gender, increased intravenous fluids, and the use of nitrous oxide, and for POV were race, additional procedures, and morphine administration. The incidence of PON and POV following orthognathic surgery in the current cohort of patients, after the introduction of the updated 2007 consensus guidelines for the management of postoperative nausea and vomiting, has not decreased substantially from that reported in 2003–2004.

    Full Text Available Abstract Background The aim of this study was to assess the results of curative surgery with and without radiotherapy in patients with T1-2N0-1 oral tongue squamous cell carcinoma (OSCC and to evaluate survival and prognostic factors. Methods Retrospective analysis of 86 patients with T1-2N0-1 OSCC who received surgery between January 2000 and December 2006. Fourteen patients (16.3% received postoperative radiotherapy (PORT. Patient characteristics, tumor characteristics, treatment modality, failure patterns, and survival rates were analyzed. Results The median follow-up was 45 months. The five-year overall survival (OS and disease-free survival (DFS rates were 80.8% and 80.2%, respectively. Higher tumor grade and invasion depth ≥ 0.5 cm were the significant prognostic factors affecting five-year OS and DFS (OS rate; 65% vs. 91%, p = 0.001 for grade; 66% vs. 92%, p = 0.01 for invasion depth: DFS rate; 69% vs. 88%, p = 0.005 for grade; 66% vs. 92%, p = 0.013 for invasion depth. In the risk group, there was no local failure in patients with postoperative radiotherapy. Conclusions In T1-2N0-1 OSCC, factors that affected prognosis after primary surgery were higher tumor grade and deep invasion depth over 0.5 cm. Postoperative radiotherapy should be considered in early oral tongue cancer patients with these high-risk pathologic features.

    By analyzing MSCT (multi-slice computed tomography) signs with different risks in gastrointestinal stromal tumors, this paper aimed to discuss the predictive value and modeling analysis of MSCT signs in GISTs (gastrointestinal stromal tumor) to pathological risk degree. 100 cases of primary GISTs with abdominal and pelvic MSCT scan were involved in this study. All MSCT scan findings and enhanced findings were analyzed and compared among cases with different risk degree of pathology. Then GISTs diagnostic model was established by using support vector machine (SVM) algorithm, and its diagnostic value was evaluated as well. All lesions were solitary, among which there were 46 low-risk cases, 24 medium-risk cases and 30 high-risk cases. For all high-risk, medium-risk and low-risk GISTs, there were statistical differences in tumor growth pattern, size, shape, fat space, with or without calcification, ulcer, enhancement method and peritumoral and intratumoral vessels (pvalue at each period (plain scan, arterial phase, venous phase) (p>0.05). The apparent difference lied in plain scan, arterial phase and venous phase for each risk degree. The diagnostic accuracy of SVM diagnostic model established with 10 imaging features as indexes was 70.0%, and it was especially reliable when diagnosing GISTs of high or low risk. Preoperative analysis of MSCT features is clinically significant for its diagnosis of risk degree and prognosis; GISTs diagnostic model established on the basis of SVM possesses high diagnostic value.

    To investigate psychological stress on the prognosis of the postoperative recurrence of keloids. Patients with keloids (n=25), candidates for surgical resection and postoperative radiotherapy, had their psychological stress evaluated on the day before the surgical procedure. The parameters evaluated were pain and itching (Visual Numerical Scale), quality of life (Questionnaire QualiFibro/Cirurgia Plástica-UNIFESP), perceived stress (Perceived Stress Scale), depression and anxiety (Hospital Depression and Anxiety Scale), salivary cortisol and minimum and maximum galvanic skin responses (GSR) at rest and under stress (i.e., while the questionnaires were being filled out). Patients were evaluated during the 3rd, 6th, 9th and 12th months of postoperative care. During each return visit, two experts classified the lesions as non-recurrent and recurrent. The recurrence group presented the greatest values in GSR during a stressful situation. The chance of recurrence increased by 34% at each increase of 1000 arbitrary units in maximum GSR during stress. Psychological stress influenced the recurrence of keloids.

    Abdominal perineal excision (APE) has been associated with a high risk of positive circumferential resection margin (CRM+) and local recurrence rates in the treatment of rectal cancer. An alternative extralevator approach (ELAPE) has been suggested to improve the quality of resection by avoiding coning of the specimen decreasing the risk of tumor perforation and CRM+. The aim of this study is to compare the quality of the resected specimen and postoperative complication rates between ELAPE and "standard" APE. All patients between 1998 and 2014 undergoing abdominal perineal excision for primary or recurrent rectal cancer at a single Institution were reviewed. Between 1998 and 2008, all patients underwent standard APE. In 2009 ELAPE was introduced at our Institution and all patients requiring APE underwent this alternative procedure (ELAPE). The groups were compared according to pathological characteristics, specimen quality (CRM status, perforation and failure to provide the rectum and anus in a single specimen-fragmentation) and postoperative morbidity. Fifty patients underwent standard APEs, while 22 underwent ELAPE. There were no differences in CRM+ (10.6 vs. 13.6%; p = 0.70) or tumor perforation rates (8 vs. 0%; p = 0.30) between APE and ELAPE. However, ELAPE were less likely to result in a fragmented specimen (42 vs. 4%; p = 0.002). Advanced pT-stage was also a risk factor for specimen fragmentation (p = 0.03). There were no differences in severe (Grade 3/4) postoperative morbidity (13 vs. 10%; p = 0.5). Perineal wound dehiscences were less frequent among ELAPE (52 vs 13%; p < 0.01). Despite short follow-up (median 21 mo.), 2-year local recurrence-free survival was better for patients undergoing ELAPE when compared to APE (87 vs. 49%; p = 0.04). ELAPE may be safely implemented into routine clinical practice with no increase in postoperative morbidity and considerable improvements in the quality of the resected specimen of patients with low rectal

    To compare the rate of postoperative dysphagia between zero-profile anchored cage fixation (ZPC group) and cage with plate fixation (CP group) after anterior cervical discectomy and fusion (ACDF). A meta-analysis of cohort studies between zero-profile anchored cage and conventional cage with plate fixation after ACDF for the treatment of cervical diseases from 2008 to May 2016. An extensive search of studies was performed in PubMed, Medline, Embase, Cochrane library and Google Scholar. Dysphagia rate was extracted. Data analysis was conducted with RevMan 5.2. Sixteen trials involving 1066 patients were included in this meta-analysis. The results suggested that the ZPC group were associated with lower incidences of dysphagia than the CP group at postoperative immediately, 2 weeks, 2, 3, 6 and 12 months. In subgroup analysis, although significant differences were only found in the mild dysphagia at 3 and 6 months postoperatively and in the moderate dysphagia at 2 weeks after surgery; the ZPC group had a lower rate of postoperative dysphagia than the CCP group in short, medium and long term follow-up periods. Zero-profile anchored cage had a lower risk of postoperative dysphagia than cage with plate.

    Postoperative radiation therapy (PORT) for cervical cancer has been empirically performed for patients with pathologic risk factors for recurrence after surgery. The efficacy of PORT is mainly supported by retrospective studies. Despite convincing evidence demonstrating a reduction in pelvic recurrence rates when PORT is employed, there is no evidence that it eventually improves patient survival. Local recurrence, such as vaginal stump recurrence, is not always fatal if diagnosed earlier. Some patients, unfortunately, may develop distant metastases even after PORT. The positive effects of PORT also may be counterbalanced by increased toxicities that result from combining local therapies. These factors obscure the efficacy of PORT for cervical cancer patients. There has been no consensus on the predictive value of risk factors for recurrence, which renders indication of PORT for early-stage cervical cancer quite variable among institutions. Today, efforts have been made to divide patients into three risk groups based on the combination of risk factors present after radical hysterectomy. In Europe/USA and Japan, however, a fundamental difference exists in the indications for radical surgery, highlighting differences in the concept of PORT; ''adjuvant pelvic irradiation for stage IB-IIA patients after complete resection'' in Europe/USA and ''pelvic irradiation after surgery irrespective of initial clinical stage and surgical margin status'' in Japan. Thus, it is questionable whether scientific evidence established in Europe/USA is applicable to Japanese clinical practice. The purpose of this article is to review the role of PORT by interpreting the results of clinical studies. (author)

    Femoral neck fractures are frequent in the elderly population and lead to high morbidity and mortality. Hemiarthroplasty is an established surgical procedure for displaced intracapsular femoral neck fractures. Post-operative infection is frequent and is potentially devastating for the patient and the healthcare services. The goal of this study was to identify the risk factors of infection after hemiarthroplasty and help adapt our surgical practice. A systematic review of the literature was performed in July 2015 by two authors using the MedLine, PubMed and Cochrane databases. We used the MeSH keywords "hip hemiarthroplasty" AND "infection" to identify risk factors and methods of prevention for surgical site infection after hemiarthroplasty. Following the search, two authors independently performed the first stage based on titles and abstracts. Thirty-seven articles were selected. Review and analysis of the references was performed to find other articles of interest. Thirteen articles were selected to analyse. According to literature, the surgical site infection (SSI) rate after hip hemiarthroplasty (HHA) is between 1.7 and 7.3 %. Pre-operative comorbidities (obesity, liver disease, advanced age), operative conditions (junior surgeon, uncemented stems, time of surgery) and post-operative management (length of hospitalisation, haematoma, prolonged wound drainage and two urinary catheterisations) were identified as risk factors of surgical site infection. Authors describe conditions to decrease the incidence of these complications and underline the importance of "a specialised hip team" that provides fast care and helps decrease the duration of hospitalisation. Careful patient management for hemiarthroplasty is vital and may decrease the incidence of surgical site infection, which is associated with high morbidity and high procedure cost. Our review suggests that there are specific correctable risk factors for SSIs after HHA. Being able to identify these risk factors

    Purpose: We sought to determine the risk of leptomeningeal disease (LMD) in patients treated with stereotactic radiosurgery (SRS) targeting the postsurgical resection cavity of a brain metastasis, deferring whole-brain radiation therapy (WBRT) in all patients. Methods and Materials: We retrospectively reviewed 175 brain metastasis resection cavities in 165 patients treated from 1998 to 2011 with postoperative SRS. The cumulative incidence rates, with death as a competing risk, of LMD, local failure (LF), and distant brain parenchymal failure (DF) were estimated. Variables associated with LMD were evaluated, including LF, DF, posterior fossa location, resection type (en-bloc vs piecemeal or unknown), and histology (lung, colon, breast, melanoma, gynecologic, other). Results: With a median follow-up of 12 months (range, 1-157 months), median overall survival was 17 months. Twenty-one of 165 patients (13%) developed LMD at a median of 5 months (range, 2-33 months) following SRS. The 1-year cumulative incidence rates, with death as a competing risk, were 10% (95% confidence interval [CI], 6%-15%) for developing LF, 54% (95% CI, 46%-61%) for DF, and 11% (95% CI, 7%-17%) for LMD. On univariate analysis, only breast cancer histology (hazard ratio, 2.96) was associated with an increased risk of LMD. The 1-year cumulative incidence of LMD was 24% (95% CI, 9%-41%) for breast cancer compared to 9% (95% CI, 5%-14%) for non-breast histology (P=.004). Conclusions: In patients treated with SRS targeting the postoperative cavity following resection, those with breast cancer histology were at higher risk of LMD. It is unknown whether the inclusion of whole-brain irradiation or novel strategies such as preresection SRS would improve this risk or if the rate of LMD is inherently higher with breast histology.

    To review the incidence of UTIs, post-operative fever, and risk factors for post-operative fever in PCNL patients. Between 2007 and 2009, consecutive PCNL patients were enrolled from 96 centers participating in the PCNL Global Study. Only data from patients with pre-operative urine samples and who received antibiotic prophylaxis were included. Pre-operative bladder urine culture and post-operative fever (>38.5°C) were assessed. Relationship between various patient and operative factors and occurrence of post-operative fever was assessed using logistic regression analyses. Eight hundred and sixty-five (16.2%) patients had a positive urine culture; Escherichia coli was the most common micro-organism found in urine of the 350 patients (6.5%). Of the patients with negative pre-operative urine cultures, 8.8% developed a fever post-PCNL, in contrast to 18.2% of patients with positive urine cultures. Fever developed more often among the patients whose urine cultures consisted of Gram-negative micro-organisms (19.4-23.8%) versus those with Gram-positive micro-organisms (9.7-14.5%). Multivariate analysis indicated that a positive urine culture (odds ratio [OR] = 2.12, CI [1.69-2.65]), staghorn calculus (OR = 1.59, CI [1.28-1.96]), pre-operative nephrostomy (OR = 1.61, CI [1.19-2.17]), lower patient age (OR for each year of 0.99, CI [0.99-1.00]), and diabetes (OR = 1.38, CI [1.05-1.81]) all increased the risk of post-operative fever. Limitations include the use of fever as a predictor of systemic infection. Approximately 10% of PCNL-treated patients developed fever in the post-operative period despite receiving antibiotic prophylaxis. Risk of post-operative fever increased in the presence of a positive urine bacterial culture, diabetes, staghorn calculi, and a pre-operative nephrostomy.

    This paper reports the results of a study of risk factors for recurrence in non-irradiated sites in patients with squamous cell carcinoma of the uterine cervix who received postoperative irradiation. It also discusses clinical experience with such patients, particularly those with a poor prognosis, based on a review of the literature. The study was conducted at the National Shikoku Cancer Center in 62 patients with squamous cell carcinoma of the uterine cervix (mean age=50.5, range=30-66) who received 10 MeV postoperative irradiation with a Linac between 1981 and 1990. An analysis was performed in terms of sites and times of recurrence, risk factors for distant metastasis, and groups at high risk for distant metastasis. Based on the results of the study as well as the review of the literature, it was concluded that squamous cell carcinoma of the uterine cervix is sensitive to radiation therapy and that the clinical outcome of local treatment is satisfactory. However, systemic chemotherapy should be considered for patients who are suspected of having minute distant metastasis at the time of surgical operation, i.e., those with moderate to severe vascular space invasion, multiple lymph node metastasis, parametrium infiltration, and/or endometrial infiltration.

    There is a range of different types of tears and pathology of the peroneal tendons. One of the least common types is the tear of the peroneus longus associated with fracture, enlargement, or entrapment at the cuboid tunnel of the os peroneum. The purpose of this study was to evaluate the pathologic patterns of these uncommon peroneal tendon tears, to review the treatment, and to report the patient outcomes following treatment with excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. A 5-year retrospective review of all patients with peroneal tendon tears identified 12 patients operatively treated for peroneus longus tendon tears with associated pathology of the os peroneum, and in whom there was a viable peroneus brevis. All patients were treated with an operative procedure consisting of excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. Mean age was 51.5 (range, 33 to 73) years, including 7 males and 5 females. Operative and radiographic records were reviewed to characterize the nature of the peroneus longus tears and associated pathology. Preoperative and postoperative AOFAS hindfoot, SF-36 questionnaires, and Visual Analog Scale (VAS) pain scores were compiled and patient records were reviewed for complications. Mean follow-up after surgery was 63.3 (range, 12 to 114) months. All of the patients had an os peroneum associated with a complex, irreparable tear of the peroneus longus tendon. The peroneus longus was typically enlarged, fibrotic, and adhered to the surrounding tissues. In 8 patients, the peroneus longus tendon tear was associated with a fracture of the os peroneum, and in 4 patients with an enlarged and entrapped os peroneum which prevented movement at the cuboid tunnel. Of the 12 patients, 9 had partial tears of the peroneus brevis, which were treated with debridement and suture repair. AOFAS hindfoot scores increased from a preoperative mean of 61

    Cervical spinal fracture is a rare, but potentially disabling complication of trauma to the neck. Clinicians often rely on clinical decision rules and guidelines to decide whether or not imaging is necessary when a patient presents with neck pain. Validated clinical guidelines include the Canadian C-Spine Rule and the Nexus criteria. Studies suggest that the risks of a pathologic fracture from a simple rear end collision are negligible. We present a case of an individual who presented to an emergency department (ED) after a low speed motor vehicle collision complaining of lateral neck pain and had multiple subsequent visits for the same complaint with negative exam findings. Ultimately, he was found to have a severely pathologic cervical spine fracture with notable cord compression. Our objective is to discuss the necessity to incorporate clinical decision rules with physician gestalt and the need to take into account co-morbidities of a patient presenting after a minor MVC.

    Full Text Available BACKGROUND: Intellectually disabled patients have various comorbidities, but their risks of adverse surgical outcomes have not been examined. This study assesses pre-existing comorbidities, adjusted risks of postoperative major morbidities and mortality in intellectually disabled surgical patients. METHODS: A nationwide population-based study was conducted in patients who underwent inpatient major surgery in Taiwan between 2004 and 2007. Four controls for each patient were randomly selected from the National Health Insurance Research Database. Preoperative major comorbidities, postoperative major complications and 30-day in-hospital mortality were compared between patients with and without intellectual disability. Use of medical services also was analyzed. Adjusted odds ratios using multivariate logistic regression analyses with 95% confidence intervals were applied to verify intellectual disability's impact. RESULTS: Controls were compared with 3983 surgical patients with intellectual disability. Risks for postoperative major complications were increased in patients with intellectual disability, including acute renal failure (odds ratio 3.81, 95% confidence interval 2.28 to 6.37, pneumonia (odds ratio 2.01, 1.61 to 2.49, postoperative bleeding (odds ratio 1.35, 1.09 to 1.68 and septicemia (odds ratio 2.43, 1.85 to 3.21 without significant differences in overall mortality. Disability severity was positively correlated with postoperative septicemia risk. Medical service use was also significantly higher in surgical patients with intellectual disability. CONCLUSION: Intellectual disability significantly increases the risk of overall major complications after major surgery. Our findings show a need for integrated and revised protocols for postoperative management to improve care for intellectually disabled surgical patients.

    Exercise dependence (EXD) is considered a behavioral addiction that is often associated with eating disorders. To date, only few studies examined the potential overlap between EXD and other addictive behaviors. Therefore, the present study aimed at investigating the relationship of EXD with pathological buying, pathological video gaming (offline and online), hypersexual behavior, and alcohol use disorder in a sample of clients of fitness centers. The following questionnaires were answered by 128 individuals (age M = 26.5, SD = 6.7 years; 71.7% men, 74.2% university students): Exercise Dependence Scale, Eating Disorder Examination-Questionnaire, Compulsive Buying Scale, Pathological Computer-Gaming Scale, Hypersexual Behavior Inventory, and Alcohol Use Disorders Identification Test (AUDIT). 7.8% of the sample were at-risk for EXD, 10.9% reported eating disorder pathology, 2.3% pathological buying, 3.1% hypersexual behavior, and none of the participants suffered from pathological video gaming. The criteria for severe alcohol disorder pathology (AUDIT ≥ 16) were fulfilled by 10.2%. With regard to continuous symptom scores, EXD symptoms were positively correlated with both eating disorder pathology and pathological buying but not with pathological video gaming, hypersexuality or alcohol use disorder. It is noteworthy that more symptoms of pathological buying corresponded with more symptoms of hypersexual behavior. The correlation pattern did not differ by gender. The co-occurrence of EXD, pathological buying and hypersexual behavior on a subclinical level or in the early stage of the disorders should be taken into account when assessing and treating patients. More research is warranted in order to investigate possible interactions between these conditions.

    Objective: To determine MR manifestations and pathologic types of benign meningiomas and their relationship with tumor recurrence. Methods: There were 218 patients (160 females,58 males; age range 4-79 years) with benign meningiomas in the study, including 31 recurrent meningiomas (recurrence group)and 187 primary meningiomas (primary group). All patients were proved by postoperative pathology. Differences of pathological types and MRI manifestations between the recurrence group and the primary group were evaluated by using χ 2 test and rank sum test. Logistic regression analysis was performed by taking tumor recurrence as the dependent variable, and age, gender, vital structures involvement and pathologic types as independent variables. The recurrent time intervals were compared by rank sum test. Results: There were 30 patients with intracranial vital structures involvement or extreintracranial communication tumors in the recurrent group, which was obviously higher than that of the primary group (61 patients). The difference was statistically significant (χ 2 =57.672, P=0.001). The tumors located in the skull-base and juxtasinus in the recurrent group were obviously more than those in the primary group, and difference was statistically significant (χ 2 =10.990, P=0.001). Multi-logistic regression analysis showed that the recurrent risk of benign meningiomas was elevated significantly only with vital structure involvement or extreintracranial communication tumors (wald χ 2 =31.863, OR=3.820, P=0.001). The recurrent risk of dural sinus involvement was 3.820 times of cerebral artery trunk and cranial nerves involvement, and the risk of the latter was 3.820 times of the non-involved. There was no statistical difference between the two groups in pathology type, location, peritumoral edema, tumor morphology and tumor size. The relapse time of dural sinus involvement and cerebral artery trunk involvement in the recurrent group was 24(13 to 180) and 126(12 to 187

    With dwindling rates of postoperative mortality in perforated peptic ulcer that is attributable to H2-receptor blocker usage, there is a need to shift the focus towards the prevention of postoperative morbidity. Further, the simultaneous contribution of several putative clinical predictors to this postoperative morbidity is not fully appreciated. Our objective was to assess the predictors of the risk, rate and number of postoperative complications in surgically treated patients of perforated peptic ulcer. In a prospective cohort study of 96 subjects presenting as perforated peptic ulcer and treated using Graham's omentoplatsy patch or gastrojejunostomy (with total truncal vagotomy), we assessed the association of clinical predictors with three domains of postoperative complications: the risk of developing a complication, the rate of developing the first complication and the risk of developing higher number of complications. We used multiple regression methods - logistic regression, Cox proportional hazards regression and Poisson regression, respectively - to examine the association of the predictors with these three domains. We observed that the risk of developing a postoperative complication was significantly influenced by the presence of a concomitant medical illness [odds ratio (OR) = 8.9, p = 0.001], abdominal distension (3.8, 0.048) and a need of blood transfusion (OR = 8.2, p = 0.027). Using Poisson regression, it was observed that the risk for a higher number of complications was influenced by the same three factors [relative risk (RR) = 2.6, p = 0.015; RR = 4.6, p management in patients of perforated peptic ulcer.

    Full Text Available Introduction. Surgical treatment of perforated peptic ulcer (PPU is a challenge for surgeons in Africa. Aim. To determine risk factors of postoperative complications or mortality among black Ivoirian patients with PPU. Methods. All 161 patients (median age = 34 years, 90.7 male operated on for PPU in the visceral and general surgery unit were enrolled in a retrospective cohort study. Variables were studied with Kaplan Meier and Cox proportional hazard models. Results. Among 161 patients operated on for PPU, 36 (27.5% experienced complications and 31 (19.3% died. Follow-up results were the incidence of complications and mortality of 6.4 (95% CI: 4.9–8.0 per 100 person-days and 3.0 (95% CI: 1.9–4.0 per 100 person-days for incidence of mortality. In multivariate analysis, risk factors of postoperative complications or mortality were comorbidities (HR = 2.1, P=0.03, tachycardia (pulse rate > 100/minutes (HR = 2.4, P=0.02, purulent intra-abdominal fluid collection (HR = 2.1, P=0.04, hyponatremia (median value ≤ 134 mEq/L (HR = 2.3, P=0.01, delayed time of hospital admission > 72 hours (HR = 2.6, P<0.0001, and delayed time of surgical intervention between 24 and 48 hours (HR = 3.8, P<0.0001. Conclusion. The delayed hospital admission or surgical intervention and hyponatremia may be considered as additional risk of postoperative complications or mortality in Black African patients with PPU.

    In order to improve our understanding of the role of postoperative radiotherapy and to search for new strategies in the management of N 1 , N 2 , T 3 stage carcinoma of the lung, we analyzed results of treatment in 148 of 166 patients who were registered at the Massachusetts General Hospital Tumor Registry from 1971 to 1977 with a pathological diagnosis of N 1 , N 2 , T 3 carcinoma of the lung after pulmonary resection. Ninety-three patients received postoperative radiotherapy and another 55 were followed without further treatment. Patients with adenocarcinoma showed significant improvement of survival by postoperative radiotherapy; actuarial NED (no evidence of disease) survival rates were 85% and 51% at 1 year, and 43% and 8% at 5 years for S + RT (patients treated with surgery plus postoperative radiotherapy) and S (patients treated with surgery only) groups, respectively, (P 2 , T 3 stages. Regional recurrence was the most common failure in squamous cell carcinoma; 76% (13/17) and 45% (10/22) of all failures were in the regional area in S and S + RT groups. Regional failure in S + RT group was noted with radiation dose up to 5000 rad (TDF 82) which suggests radiation dose higher than 5000 rad in future trial

    Postoperative delirium is a common occurrence in older patients. However, reports of postoperative delirium in middle-aged patients are limited, and the underlying mechanism of delirium in this patient population is not clear. A 45-year-old man who developed postoperative delirium on the second day after partial laryngectomy. Interviews of the surgical team, patient, and patient's spouse revealed that the patient was psychologically stressed, but had not been diagnosed or treated. The patient also suffered impairment in physiological functioning and sleep disturbance after surgery. Postoperative delirium. The postoperative delirium was treated with an antipsychotic drug. The patient recovered well. Preoperative psychological stress, which is often undiagnosed and untreated, can increase the risk of postoperative delirium in middle-aged patients undergoing laryngectomy. Therefore, screening for psychological stress and implementing strategies to prevent delirium should be considered for patients who undergo laryngectomy, even if they are not in high-risk older age groups.

    To determine if postoperative urinary retention and urinary tract infections (UTIs) were predictors of future mesh complications requiring surgical intervention after midurethral sling (MUS). Administrative data in Ontario, Canada, between 2002 and 2013 were used to identify all women who underwent a mesh-based MUS. The primary outcome was revision of the transvaginal mesh sling (including mesh removal/erosion/fistula, or urethrolysis). Two potential risk factors were analyzed: postoperative retention (within 30 days of procedure) and number of postoperative emergency room visits or hospital admissions for UTI symptoms. A total of 59,556 women had a MUS, of which 1598 (2.7%) required revision surgery. Of the 2025 women who presented to the emergency room or were admitted to hospital for postoperative retention, 212 (10.5%) required operative mesh revision. Of the 11,747 patients who had at least one postoperative UTI, 366 (3.1%) patients required operative mesh revision. In adjusted analysis, postoperative retention was significantly predictive of future reoperation (hazard ratio [HR] 3.46, 95% confidence interval [CI] 2.97-4.02), and this difference persisted when urethrolysis was excluded as a reason for sling revision (HR 3.08, 95% CI 2.62-3.63). Similarly, in adjusted analysis, each additional postoperative hospital visit for UTI symptoms increased the risk for surgical intervention for mesh complications (HR 1.74, 95% CI 1.61-1.87). Postoperative urinary retention and hospital presentation for UTI symptoms are associated with an increased risk of reoperation for MUS complications. These patients should be followed and investigated for mesh complications when appropriate. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Purpose: Pathologic fractures in patients with bone metastases are a common problem in clinical orthopaedic routine. On one hand recognition of metastatic lesions, which are at a high risk of fracture, is essential for timely prophylactic fixation, while on the other hand patients with a low risk of pathologic fractures should be spared from overtreatment.The purpose of this review is to identify all methods for fracture risk evaluation in patients with femoral metastases in the literature and to evaluate their predictive values in clinical applications. Methods: A MEDLINE database literature research was conducted in order to identify clinical scoring systems, conclusions from prospective and retrospective radiologic and/or clinical studies, as well as data from biomechanical experiments, numerical computational methods, and computer simulations. Results: The search identified 441 articles of which 18 articles met the inclusion criteria; 4 more articles were identified from citations of the primarily found studies. In principle there are two distinct methodologies, namely fracture risk prediction factors based on clinical and radiological data such as the most deployed the Mirels' score and fracture risk prediction based on engineering methods. Fracture risk prediction using Mirels' score, based on pure clinical data, shows a negative predictive value between 86 and 100%, but moderate to poor results in predicting non-impending fractures with a positive predictive value between 23 and 70%. Engineering methods provide a high accuracy (correlation coefficient between ex vivo and results from numerical calculations: 0.68 < r2 < 0.96 in biomechanical lab experiments, but have not been applied to clinical routine yet. Conclusion: This review clearly points out a lack of adequate clinical methods for fracture risk prediction in patients with femoral metastases. Today's golden standard, the Mirels' score leads to an overtreatment. Whereas

    The aim of the present study was to investigate the risk factors for postoperative recurrence of spinal tumors by logistic regression analysis and analysis of prognostic factors. In total, 77 male and 48 female patients with spinal tumor were selected in our hospital from January, 2010 to December, 2015 and divided into the benign (n=76) and malignant groups (n=49). All the patients underwent microsurgical resection of spinal tumors and were reviewed regularly 3 months after operation. The McCormick grading system was used to evaluate the postoperative spinal cord function. Data were subjected to statistical analysis. Of the 125 cases, 63 cases showed improvement after operation, 50 cases were stable, and deterioration was found in 12 cases. The improvement rate of patients with cervical spine tumor, which reached 56.3%, was the highest. Fifty-two cases of sensory disturbance, 34 cases of pain, 30 cases of inability to exercise, 26 cases of ataxia, and 12 cases of sphincter disorders were found after operation. Seventy-two cases (57.6%) underwent total resection, 18 cases (14.4%) received subtotal resection, 23 cases (18.4%) received partial resection, and 12 cases (9.6%) were only treated with biopsy/decompression. Postoperative recurrence was found in 57 cases (45.6%). The mean recurrence time of patients in the malignant group was 27.49±6.09 months, and the mean recurrence time of patients in the benign group was 40.62±4.34. The results were significantly different (Pregression analysis of total resection-related factors showed that total resection should be the preferred treatment for patients with benign tumors, thoracic and lumbosacral tumors, and lower McCormick grade, as well as patients without syringomyelia and intramedullary tumors. Logistic regression analysis of recurrence-related factors revealed that the recurrence rate was relatively higher in patients with malignant, cervical, thoracic and lumbosacral, intramedullary tumors, and higher Mc

    Liver transplantation is the only effective and definitive treatment for patients with end-stage liver disease. The shortage of cadaveric livers has lead to the increasing use of split-liver transplantation and living-donor liver transplantation, but the expansion of the donor pool has increased the risk for postoperative vascular and biliary complications. Early recognition of the imaging appearances of the various postoperative complications of liver transplantation is crucial for both graft and patient survival. This review describes the imaging findings of normal and abnormal transplanted liver parenchyma and of vascular and biliary post-transplantation complications. (orig.)

    Facial resurfacing with a CO 2 laser has been used for treatment of pathologic lesions and for cosmetic purposes. Postoperative complications and problems after laser resurfacing include infections, acneiform lesions, and pigment changes. This retrospective study describes the most common problems and complications in 105 patients and assesses postoperative pain in 38 patients. All patients received CO 2 laser resurfacing for treatment of malignant/premalignant lesions and had postoperative follow-up to assess problems and complications. Some had follow-up to assess postoperative pain. All patients had Fitzpatrick I-III skin types and underwent the same perioperative care regimen. There were 11 problems and 2 complications. Problems included infection, acneiform lesion/milia, and uncontrolled postoperative pain. Complications included hyperpigmentation. Among the postoperative pain group, 53% reported no pain and the rest had mild or moderate pain. Complications are rare. Infection and acneiform lesions/milia were the most common problems, as previously reported. Most patients do not experience postoperative pain. Copyright © 2016 Elsevier Inc. All rights reserved.

    To evaluate the predictors of postoperative nausea and vomiting (PONV) in women with gynecologic tumor. The analysis was based on prospectively collected data of 82 adult patients with gynecologic tumor, who were submitted to open surgical treatment and undergoing general anesthesia. The predictors included were age ≥50 years, non-smoker, use of postoperative opioids, mechanical bowel preparation, intraoperative intravenous hydration (IH) ≥10 mL/kg/h, and IH in the immediate postoperative, first and second postoperative days (PO1 and PO2) ≥30 mL/kg. A score with predictor variables was built. A multiple logistic regression was fitted. To estimate the discriminating power of the chosen model, a receiver operating characteristic (ROC) curve was plotted and the area under the ROC curve (AUC) was calculated. Statistical significance was set at p value 30 mL/kg of IH in the PO2. The results of the adjusted model showed an increased risk of PONV for each 1-point increase in the score punctuation. The relative risk was higher than 2.0 for vomiting in all period and in the PO1. The ROC curve showed great discrimination of postoperative nausea and vomiting from the proposed score (AUC >0.75). The study population was at high risk of PONV. Therefore, institutional guidelines abolishing modificable variables following temporal evaluation of the effectiveness should be undertaken.

    Fall-induced injuries represent a major public health concern for older individuals. The relationship between risk of falling and the severity of locomotive syndrome (LS) remains largely unknown. We conducted a retrospective analysis of patients who had undergone surgery from January 2012 to December 2013 and completed at least 1 year of follow-up at 12 participating institutes. Patients completed a questionnaire survey regarding their fall experience during a routine postoperative follow-up. Questionnaire items included the number of falls during the prior postoperative year and the 25-question Geriatric Locomotive Function Scale (GLFS-25). The severity of cervical myelopathy was assessed using the Japanese Orthopaedic Association (JOA) score. We analyzed the association between the incidence of falling and the severity of LS measured by the GLFS-25. Of 360 patients, 61 (16.9%) experienced 1 fall; 31 (8.6%), 2-3 falls; 4 (1.1%), 4-5 falls; and 6 (1.7%), ≥6 falls during the first postoperative year. Thus, 102 (28%) patients experienced at least 1 fall, and 41 (11%) experienced recurrent falls (2 or more falls) during the time period. The mean GLFS-25 score was 30.2 ± 22.7, and 242 (62%) patients had GLFS-25 scores of 16 or higher, which fulfilled the diagnostic criteria for LS. When subjects were categorized into recurrent fallers and non-recurrent fallers, recurrent fallers had a significantly higher GLFS-25 score and a significantly lower extremity motor function score of the JOA score than non-recurrent fallers. The GLFS-25 and lower extremity motor function score of the JOA score yielded the areas under the receiver operating characteristic curves of 0.674 and 0.607, respectively, to differentiate recurrent fallers from non-recurrent fallers. Postoperative patients with cervical myelopathy had a 62% prevalence of LS. The GLFS-25 may be useful to predict the risk of recurrent falls in patients with cervical myelopathy.

However, research concerning POD in IVPCA patients is limited. Objective: We aimed to determine the incidence, risk factors, and phenomenological characteristics of POD in patients receiving IVPCA. Methods: A prospective, cohort study was conducted in post-general anesthesia IVPCA patients aged ≥60 years. POD was measured by the Nursing Delirium Screening Scale (NuDESC; 0–10. Delirium, pain severity at rest and/or on movement, and side effects of IVPCA during 3 postoperative days were examined twice-daily by the acute pain service team. Pain severity is measured by an 11-point verbal numerical rating scale (11-point VNRS (0–10. An 11-point VNRS >3 was considered inadequate pain relief. If POD (detected by NuDESC ≥1 is suspected, consulting a neurologist or a psychiatrist to confirm suspected POD is required. Results: In total, 1,608 patients were included. The incidence rate of POD was 2.2%. Age ≥70 years and American Society of Anesthesiologists physical status >III were the risk factors of POD in IVPCA patients. Approximately three-quarters of all POD cases occurred within the first 2 postoperative days. For pain at rest, patients with inadequate pain relief had significantly greater rates of POD than patients with adequate pain relief (day 1, 8.4% vs 1.5%, P<0.001; day 2, 9.6% vs 2.0%, P=0.028; day 3, 4.1% vs 2.1%, P=0.412. However, the incidence of POD was not associated with movement-evoked pain relief. Most (79.9% POD cases in IVPCA patients showed either one or two symptoms. The

    Full Text Available Introduction: Delirium as a relatively common complication following cardiac surgery remains a contributory factor in postoperative mortality and an obstacle to early discharge of patients.Methods: In the present study 329 patients who underwent open heart surgery between 1st January 2008 to 1st January 2009 in Shahid Madani Heart Center, Tabriz, Iran were enrolled.Results: Overall 4.9% of patients developed delirium after cardiac surgery. We found atrial fibrillation (P = 0.005, lung diseases (P = 0.04 and hypertension (P = 0.02 to be more common in patients who develop delirium postoperatively. Furthermore, the length of intensive care unit (ICU stay, cardiopulmonary bypass (CPB time, and ventilation period were also significantly increased. Also a statistically meaningful relationship between the female gender and development of delirium was also noted (P = 0.02. On the other hand no meaningful relationship was detected between diabetes, history of cerebral vascular diseases, peripheral vascular diseases, myocardial infarction, development of pneumonia following surgery, and laboratory levels of sodium, potassium, glucose, and complete blood cell count (CBC including white blood cells, red blood cells, platelets in the blood-hemoglobin and hematocrits. Also environmental factors like presence of other patients or companion with the patient, and objects like clock, window and calendar in the patient’s room did not affect prevention of delirium.Conclusion: Based on this and other investigations, it can be suggested to use MMPI test to recognize pathologic elements to prevented delirium after surgery and complementary treatment for coping with delirium.

    Our aim was to examine the predictors of cardiovascular disorders in children affected by obstructive sleep apnea syndrome (OSAS) based on the results of polysomnography and continuous monitoring of blood glycose. Before the examination, parents filled in questionnaires concerning their children sleep quality. The procedure was followed by the study of the sleep by means of polysomnography (Embla s 7000, USA). A system of continuous monitoring of blood glucose was applied (Guardianreal-time, Medtronicminimed, USA) by means of which a glycemic profile tissue fluid was studied. A night sleep research of 120 children aged 3-16 y.o. is presented. There were 4 groups depending on the pathology: diseases of the nervous system (n = 31), ENT-pathology (n = 18), bronchial asthma (n = 24) and overweight and obesity (n = 34). The comparison group consisted of 13 apparently healthy children. The study has shown that the parents of every second child with sleep disorders did not know about the fact. The 60 % of the patients with high body mass index (BMI) had a snore, which was significantly higher the in children with normal body mass index--35% (p = 0.012). The index of apnea-hypopnea (AHI) was higher in the patients with ENT-pathology 17 times (p 1sd). Children with ENT-pathology and with high high body mass index have high risk of cardio-vascular diseases. Children with above average stature and with increased body mass index affected by OSAS have additional backgrounds for cardiovascular diseases develop- ment as a result of the latent periods of hypoglycemia at night.

    2016-01-01

    Full Text Available The circadian system is a supraphysiological system that modulates different biological functions such as metabolism, sleep-wake, cellular proliferation, and body temperature. Different chronodisruptors have been identified, such as shift work, feeding time, long days, and stress. The environmental changes and our modern lifestyle can alter the circadian system and increase the risk of developing pathologies such as cancer, preeclampsia, diabetes, and mood disorder. This system is organized by transcriptional/tranductional feedback loops of clock genes Clock, Bmal1, Per1–3, and Cry1-2. How molecular components of the clock are able to influence the development of diseases and their risk relation with genetic components of polymorphism of clock genes is unknown. This research describes different genetic variations in the population and how these are associated with risk of cancer, metabolic diseases such as diabetes, obesity, and dyslipidemias, and also mood disorders such as depression, bipolar disease, excessive alcohol intake, and infertility. Finally, these findings will need to be implemented and evaluated at the level of genetic interaction and how the environment factors trigger the expression of these pathologies will be examined.

    Development of acute kidney injury (AKI) during the perioperative period is associated with increases in morbidity and mortality. Our aim was to evaluate the incidence and determinants of postoperative AKI after major noncardiac surgery in patients with previously normal renal function. This retrospective cohort study was carried out in the multidisciplinary Post-Anaesthesia Care Unit (PACU) with five intensive care beds. The study population consisted of 1166 patients with no previous renal insufficiency who were admitted to these intensive care unit (ICU) beds over 2 years. After admission patients were followed for the development of AKI, defined as proposed by The Acute Kidney Injury Network (increment of serum creatinine [greater than or equal to] 0.3 mg/dL or 50% from baseline within 48 hours or urine output 6 hours despite fluid resuscitation when applicable). Patient preoperative characteristics, intraoperative management and outcome were evaluated for associations with acute kidney injury using an univariate and multiple logistic regression model. A total of 1597 patients were admitted to the PACU and of these, 1166 met the inclusion criteria. Eighty-seven patients (7.5%) met AKI criteria. Univariate analysis identified age, American Society of Anesthesiologists (ASA) physical status, emergency surgery, high risk surgery, ischemic heart disease, congestive heart disease and Revised Cardiac Risk Index (RCRI) score as independent preoperative determinants for AKI in the postoperative period. Multivariate analysis identified ASA physical status, RCRI score, high risk surgery and congestive heart disease as preoperative determinants for AKI in the postoperative period. Patients that developed AKI had higher Simplified Acute Physiology Score (SAPS) II and Acute Physiology and Chronic Health Evaluation (APACHE) II, higher PACU length of stay (LOS), higher PACU mortality, higher hospital mortality and higher mortality at 6 months follow-up. AKI was an independent

    The purpose of the present study was to analyze the management of surgical third molar extraction and postoperative progress in patients with a diagnosis of factor VII deficiency. Close collaboration between the oral-maxillofacial surgeon and hematologist will allow the team to categorize the risk and operate safely, thereby minimizing the incidence and severity of intraoperative and postoperative complications. The present retrospective study included 7 patients with factor VII deficiency who had undergone third lower molar surgery. Their factor VII deficiency ranged from 10.5 to 21.0%. Recombinant activated factor VII (rFVIIa) (coagulation factor VIIa [recombinant]; NovoSeven RT; Novo Nordisk, Bagsvaerd, Denmark) was transfused intravenously in a single dose of 25 μg/kg body weight, 30 minutes before surgical extractions. After the surgery, betamethasone, an analgesic, and an ice pack were administered. Pretreatment with recombinant activated factor VII resulted in excellent hemostasis. No hemorrhagic complications and no postoperative major bleeding were observed. The extraction of the third lower molar appears to be a safe procedure for patients with factor VII deficiency when appropriate prophylaxis with rFVIIa is used.

    To clarify the indications for permanent seed implantation monotherapy in patients with intermediate-risk prostate cancer, pathological differences in radical prostatectomy specimens between low- and intermediate-risk prostate cancer were assessed. Fifty-three cases in the low-risk group and 96 cases in the intermediate-risk group had their radical prostatectomy specimens pathologically evaluated between April 2000 and January 2009. Patients with radical prostatectomy specimens of pT2 and Gleason score ≤3+4 were defined as the favorable group, while those with ≥pT3a and/or Gleason score ≥4+3 were defined as the unfavorable group. The favorable group was made up of 67.9%, 81.2%, 73.9%, 73.3%, 23.5% and 24.0% low-risk group cases, ≤T2a, GS 3+3 and 10< prostatic specific antigen (PSA)≤20 ng/ml cases, ≤T2a, GS 3+4 and PSA ≤10 ng/ml cases, ≤T2a, GS 3+4 and 10< PSA≤20 ng/ml cases, ≤T2a, GS 4+3 and PSA ≤20 ng/ml cases and T2b, GS ≤4+3 and PSA ≤20 ng/ml cases, respectively. The rate of unfavorable group in cases with ≤T2a, GS 4+3 and PSA ≤20 ng/ml, and cases with T2b, GS ≤4+3 and PSA ≤20 ng/ml was statistically higher than that in the low-risk group. Accordingly, cancer volume in cases with T2b, GS ≤4+3 and PSA ≤ 20 ng/ml was statistically larger than that in the low-risk group. Cancer volume in intermediate-risk groups other than ≤T2a, GS 3+4 and PSA ≤10 ng/ml tended to be larger than that in the low-risk group. As for radical prostatectomy specimens, the pathological findings of cases with ≤T2a, GS 3+4 and PSA ≤10 ng/ml were similar to those of cases in the low-risk group. The outcome for permanent seed implantation monotherapy with a conventional dose in cases with ≤T2a, GS 3+4 and PSA ≤10 ng/ml may be similar to that of cases in the low-risk group from a pathological aspect.

    It is essential to preserve as many of the parathyroid glands, as possible, during surgery of the thyroid gland. This is achieved by visualizing them and by minimal handling of the glands. Truncal ligation of the inferior thyroid artery is quite safe. Capsular ligation of the branches of the artery is theoretically superior but requires a greater degree of skill and experience in thyroid surgery. It also puts the recurrent laryngeal nerve at a greater risk of injury. Calcitriol or 1.25 dihydroxy vitamin D is a very useful drug in managing patients with severe post-operative hypoparathyroidism

    Hospital readmissions following bariatric surgery are high and it is necessary to identify modifiable risk factors to minimize this postoperative cost. We hypothesize that lower levels of education and health literacy are associated with increased risks of nonadherence, thus leading to increased emergency department (ED) visits and preventable readmissions postoperatively. Bariatric surgery patients presenting between October 2015 and December 2016 were administered a preoperative questionnaire that measured education level and the Rapid Estimate of Adult Literacy in Medicine-Short Form (REALM-SF) health literacy test. The rates of postoperative ED visits and readmissions were across education levels (≤12th grade versus >12th grade) and health literacy scores (≤8th grade versus high school level). A composite "hospital visit" outcome was also assessed. Ninety-five patients were enrolled; 23 had ≤12th grade level education and 7 scored ≤8th grade on the REALM-SF. Patients with ≤12th grade education were significantly more likely to have a hospital visit after surgery, compared with patients with >12th grade education (incidence rate ratio [IRR] 3.06, P = .008). No significant difference in ED visits, readmission, or hospital visits was seen when stratified by REALM-SF health literacy score. Lower level of education was associated with more than threefold increased risk of postoperative ED visits and readmission in our center's bariatric surgery patients. A patient's education level is a low-cost means to identify patients who are at risk for postoperative hospital visits, and who may benefit from enhanced educational efforts or more intensive postoperative follow-up.

    Full Text Available Aim: improving the results of the complex treatment of patients with surgical pathology of abdominal organs by improving prevention and treatment of motor-evacuation disorders of the gastrointestinal tract in the postoperative period. Results: the article presents data on the use of metoclopramide, L- ar¬ginine, simethicone for the prevention of postoperative dysmotility development. It is proved that L-arginine use reduces the effects of peripheral vasospasm by improving microcirculation of the intestinal wall and this leads to a more rapid recovery of motor-evacuation function of the gastrointestinal tract.

    Purpose To report the results of the Trans Tasman Radiation Oncology Group randomized phase III trial designed to determine whether the addition of concurrent chemotherapy to postoperative radiotherapy (CRT) improved locoregional control in patients with high-risk cutaneous squamous cell carcinoma of the head and neck. Patients and Methods The primary objective was to determine whether there was a difference in freedom from locoregional relapse (FFLRR) between 60 or 66 Gy (6 to 6.5 weeks) with or without weekly carboplatin (area under the curve 2) after resection of gross disease. Secondary efficacy objectives were to compare disease-free survival and overall survival. Results Three hundred twenty-one patients were randomly assigned, with 310 patients commencing allocated treatment (radiotherapy [RT] alone, n = 157; CRT, n = 153). Two hundred thirty-eight patients (77%) had high-risk nodal disease, 59 (19%) had high-risk primary or in-transit disease, and 13 (4%) had both. Median follow-up was 60 months. Median RT dose was 60 Gy, with 84% of patients randomly assigned to CRT completing six cycles of carboplatin. The 2- and 5-year FFLRR rates were 88% (95% CI, 83% to 93%) and 83% (95% CI, 77% to 90%), respectively, for RT and 89% (95% CI, 84% to 94%) and 87% (95% CI, 81% to 93%; hazard ratio, 0.84; 95% CI, 0.46 to 1.55; P = .58), respectively, for CRT. There were no significant differences in disease-free or overall survival. Locoregional failure was the most common site of first treatment failure, with isolated distant metastases as the first site of failure seen in 7% of both arms. Treatment was well tolerated in both arms, with no observed enhancement of RT toxicity with carboplatin. Grade 3 or 4 late toxicities were infrequent. Conclusion Although surgery and postoperative RT provided excellent FFLRR, there was no observed benefit with the addition of weekly carboplatin.

    Crohn's disease is a chronic, progressive disabling condition ultimately leading to stricturing and/or penetrating complications. The need for surgery may be as high as 70% in patients with severe active disease or complications. However, relapse may develop in a significant proportion of the patients after surgery leading to frequent re-operations. Despite emerging data, postoperative prevention is still controversial. After careful evaluation of the individual risk a tailored therapy should be considered. In patients with small risk for relapse mesalazine or in selected cases no-treatment may be an option. In patients with a moderate-to-high risk azathioprine should be considered together with metronidazole in the three months. Follow-up ileocolonoscopy 6-12 months after the surgery is helpful in the determination of endoscopic severity and may assist in the optimization of the therapy. In most severe cases anti-TNF agents may be appropriate for postoperative prevention and therapy.

    A retrospective analysis. To evaluate the association between early postoperative dural sac cross-sectional area (DCSA) and radicular pain. The correlation between postoperative magnetic resonance imaging (MRI) findings and postoperative neurological symptoms after lumbar decompression surgery is controversial. This study included 115 patients who underwent lumbar decompression surgery followed by MRI within 7 days postoperatively. There were 46 patients with early postoperative radicular pain, regardless of whether the pain was mild or similar to that before surgery. The intervertebral level with the smallest DCSA was identified on MRI and compared preoperatively and postoperatively. Risk factors for postoperative radicular pain were determined using univariate and multivariate analyses. Subanalysis according to absence/presence of a residual suction drain also was performed. Multivariate regression analysis showed that smaller postoperative DCSA was significantly associated with early postoperative radicular pain (per -10 mm; odds ratio, 1.26). The best cutoff value for radicular pain was early postoperative DCSA of 67.7 mm. Even with a cutoff value of surgery. The best cutoff value for postoperative radicular pain was 67.7 mm. Absence of a suction drain at the time of early postoperative MRI was related to smaller DCSA.

    Postoperative radiochemotherapy was included to the therapeutic scheme of stomach cancer. The effectiveness and tolerance of pre- and postoperative radiochemotherapy were studied. A Range Scale Risk reflecting the risk of treatment failure , selecting patients with bad prognosis to intensive therapy was established on the base of identified predictive and prognostic factors. 426 patients with stomach cancer were undergone radiochemotherapy between 1999 and 2005. The therapeutic schemes with operation followed by adjuvant radiochemotherapy or pre-and postoperative radiochemotherapy were arranged.The overall survival was better in the second group. Body weight loss, age and performance status of patients, location of tumor, cancer stage evaluation, resected lymph nodes, operation radicality were identified as the independent prognostic factors. In conclusions, combined modality approaches in treatment of stomach cancer were shown as more effective than surgery alone. Neoadjuvant chemotherapy may be more effective than postoperative one. Postoperative radiochemotherapy started and completed within 5 weeks positively influenced all prognostic factors. 5-year overall survival rate was 66% and risk of local recurrence less than 15%. 4 prognostics groups of patients selected in 10 points scale of range scale risk by careful evaluation using hazard model were established and detailed results have been presented.

    Patient selection remains paramount when developing and adopting quality-based assessment and reimbursement models, and enhanced recovery protocols. Gender is a patient characteristic known before surgery which can inform risk stratification. Our aim was to evaluate the effect of gender on intraoperative blood transfusions, operative time, length of hospital stay, estimated blood loss (EBL) as well as postoperative surgical site infections (SSIs), and mortality. Patients undergoing elective pancreatectomy from 2005 to 2013 were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and Northwestern institutional databases. Multivariable analyses were conducted to identify the association between gender and these outcomes. Analyses demonstrated that male gender was independently associated with blood transfusion (OR 1.23), operative time >6 hr (OR 1.76), length of stay greater than 11 days (OR 1.17), and all-type SSIs (OR 1.17), especially superficial SSIs (OR 1.15) and organ space SSIs (OR 1.18). Analysis of the institutional cohort found that male gender was independently associated with increased odds of EBL > 1 L for Whipple procedures (OR 2.85). Male gender is a significant predictor of increased operative time, length of stay, transfusions, EBL > 1L, as well as postoperative organ space surgical site infections in these patients. J. Surg.

    Full Text Available Background and Aims: Aging population is a major demographic trend worldwide. Globally, 50% of all the elderly individuals are estimated to undergo atleast one surgical procedure and post-operative cognitive dysfunction (POCD is one of the most common and often poorly understood post-operative complications in this section of the population. This randomised prospective study was conducted to assess the post-operative cognitive status in the elderly undergoing non-cardiac surgery, evaluate the cognitive parameters affected, evaluate the potential risk factors and thereby analyse the potential for implementation of preventive strategies. Methods: This study was conducted on 200 patients aged 60 years or older scheduled for elective non-cardiac surgeries. The baseline cognitive status of the patients was assessed 2 days prior to the date of the surgery. The post-operative cognitive status was assessed on the 3 rd day, 7 th day and after 1 month. Statistical analysis was performed using SAS and SPSS. Results: The incidence of POCD showed a gradual decline from postoperative day 3 to 30. Females were found to be at significant risk in developing POCD. Advancing age and level of education emerged as dominant factors, while type of anaesthesia, duration of surgery, and presence of coexisting comorbidities had no influence on the incidence of cognitive dysfunction. Conclusion: POCD is a definite complication after surgery and anaesthesia in the elderly population. Gender emerged as a significant risk factor with increasing age as a dominating factor contributing to POCD.

    A chronic state of impaired glucose metabolism affects multiple components of the immune system, possibly leading to an increased incidence of post-operative infections. Such infections increase morbidity, length of stay, and overall cost. This study evaluates the correlation between elevated pre-operative glycosylated hemoglobin (HbA1c) and post-operative infections. Adult patients undergoing non-emergent procedures across all surgical subspecialties from January 2010 to July 2014 had a preoperative HbA1c measured as part of their routine pre-surgical assessment. 2200 patient charts (1100 operative infection (superficial surgical site infection, deep wound/surgical space abscess, pneumonia, and/or urinary tract infection as defined by Centers for Disease Control criteria) within 30 days of surgery. Patients with HbA1c infection rate (3.8% in the HbA1c infection. Elevated HbA1c was, however, predictive of significantly increased risk of post-operative infection when associated with increased age (≥81 years of age) or dirty wounds. The risk factors of post-operative infection are multiple and likely synergistic. While pre-operative HbA1c level is not independently associated with risk of post-operative infection, there are scenarios and patient subgroups where pre-operative HbA1c is useful in predicting an increased risk of infectious complications in the post-operative period.

    Heterotopic ossification is a complication of total hip arthroplasty in 14 to 30% of patients. Significant functional impairment will occur in up to 28% of patients with ectopic bone. The high risk group includes those with preexisting heterotopic bone in either hip, those suffering from hypertrophic osteoarthritis or ankylosing spondylitis and patients who have had multiple procedures on the hip. Fifty-eight patients (67 hips) were irradiated after surgical removal of ectopic bone (53 hips) or received radiation prophylaxis of heterotopic ossification (14 hips). Ninety-five percent of patients had either no bone visible or insignificant amounts of ectopic bone visible on postoperative hip X-rays. Only 5% of patients showed significant persistence of ectopic bone. Postoperative hip function was dramatically improved compared to preoperative function in all patients treated. The importance of early commencement of irradiation is emphasized

    Purpose: We analyzed long-term local control and complications in patients with either pathologically confirmed or clinical World Health Organization Grade I meningiomas treated with definitive or postoperative radiotherapy (RT) at the University of Florida. Methods: Between 1984 and 2006, 146 patients were treated with definitive (n = 88) or postoperative RT after subtotal resection (n = 57) or gross total resection (n = 1). Patients were treated with conventional (n = 41), stereotactic (n = 103), or intensity-modulated RT (n = 2) to a median dose of 52.7 Gy and followed for a median of 7.3 years (range, 0.6-22.0 years) Results: The local control rates at 5 and 10 years were as follows: definitive RT, 99% and 99%; postoperative RT, 96% and 93%; and overall, 97% and 96%, respectively. The 5- and 10-year cause-specific survival rates were as follows: definitive RT 94% and 94%, postoperative RT, 100% and 96%; and overall, 96% and 95%, respectively. The 5- and 10-year overall survival rates were as follows: definitive RT, 81% and 75%; postoperative RT, 96% and 85%; and overall, 87% and 79%, respectively. Severe RT complications occurred in 6.8% of patients; severe surgery-related complications occurred in 10 (17%) of 58 patients treated surgically. Conclusions: The likelihood of cure after definitive RT or following subtotal resection is excellent. However, a small population of patients experience severe complications, even at the moderate dose used for this disease.

    Brain natriuretic peptide (BNP) is a cardiac neurohormone known to correlate with left ventricular (LV) dilation, decreased contractility, and increased stiffness. Consequently, BNP has been used as a prognostic tool to assess the degree of LV unloading for patients supported by continuous-flow LV assist devices (LVADs). We assessed the prognostic value of changes in BNP in the 2 weeks after LVAD implantation. This retrospective study analyzed laboratory findings and outcomes of 189 LVAD patients. Patients were separated into two groups based on whether serum BNP levels had improved from preoperative levels by postoperative day 14. Group 1 had improvement in BNP levels, whereas group 2 had no improvement or worsening in BNP. There were no significant differences between the groups in age, gender, race, body mass index, or comorbidities. Group 1 had preoperative BNP 1,125 ± 1,078.3 pg/dl and postoperative BNP 440.2 ± 267.7 pg/dl (ΔBNP = -693.09 ± 942.4 pg/dl), whereas group 2 had preoperative BNP 346.0 ± 309.1 pg/dl and postoperative BNP 631.57 ± 483.4 pg/dl (ΔBNP = 289.32 ± 329.7 pg/dl). Postoperative survival in group 2 was significantly worse than in group 1. Rates of right ventricular failure (RVF) were significantly higher in group 2 (group 1: 39%, group 2: 52.7%; p = 0.01). In most patients implanted with a LVAD, BNP improves significantly in the postoperative period as the LV is unloaded. Our results indicate that lack of improvement in postoperative BNP is associated with longer length of stay, increased rates of RVF, and is an independent risk factor for reduced postoperative survival.

    De novo interictal psychosis, albeit uncommon, can develop in patients following temporal lobe surgery for epilepsy. Pathological alterations of the dentate gyrus, including cytoarchitectural changes, immaturity and axonal reorganization that occur in epilepsy, may also underpin co-morbid psychiatric disorders. Our aim was to study candidate pathways that may be associated with the development of interictal psychosis post-operatively in patients with hippocampal sclerosis (HS). A total of 11 patients with HS who developed interictal psychosis (HS-P) post-operatively were compared with a matched surgical HS group without psychosis (HS-NP). Resected tissues were investigated for the extent of granule cell dispersion, mossy fibre sprouting and calbindin expression in the granule cells. We quantified doublecortin, mini-chromosome maintenance protein 2 (MCM2) and reelin-expressing neuronal populations in the dentate gyrus as well as the distribution of cannabinoid type 1 receptor (CBR1). The patterns of neuronal loss and gliosis were similar in both groups. HS-P patients demonstrated less mossy fibre sprouting and granule cell dispersion (p gyrus pathology found in HS-P patients could indicate underlying differences in the cellular response to seizures. These mechanisms may predispose to the development of psychosis in epilepsy and warrant further investigation.

    Full Text Available Abstract Background It is unclear when it is safe to discharge patients with a diagnosis of Obstructive Sleep Apnea (OSA after ambulatory surgical procedures due to concern for postoperative respiratory compromise and hypoxemia. Our OSA patients undergoing ambulatory-type orthopedic procedures are monitored overnight in the PACU, thus we reviewed patient records to determine incidence of complications. Methods Two hundred and six charts of patients with preoperative diagnosis of OSA based on ICD-9 codes were reviewed for outcomes including episodes of hypoxemia. Univariate analysis followed by logistic regression and propensity analysis was performed to determine independent risk factors for hypoxemia and association with adverse outcomes. Results The majority of patients had regional anesthesia (95%. Thirty four percent of patients had hypoxemia in the PACU. Initial risk factors for hypoxemia identified by univariate analysis were BMI ≥ 35, increased age, history of COPD, upper extremity procedure, and use of peripheral nerve block. Independent risk factors identified by logistic regression were history of COPD (OR 3.64 with 95% CI 1.03-12.88 and upper extremity procedure (2.53, 1.36-4.68. After adjustment with propensity scores, adverse events were rare, and unplanned hospital admission after PACU stay was not increased with hypoxemia (11% vs 16% Conclusions Episodes of postoperative hypoxemia in OSA patients undergoing ambulatory surgery with regional anesthesia are not associated with increased adverse outcomes or unplanned hospital admission.

    Full Text Available Introduction: Risk assessment for post-operative delirium (POD is poorly developed. Improved metrics could greatly facilitate peri-operative care as costs associated with POD are staggering. In this preliminary study, we develop a novel stress-diathesis model based on comprehensive pre-operative psychiatric and neuropsychological testing, a blood oxygenation level-dependent (BOLD magnetic resonance imaging (MRI carbon dioxide (CO2 stress test, and high fidelity measures of intra-operative parameters that may interact facilitating POD.Methods: The study was approved by the ethics board at the University of Manitoba and registered at clinicaltrials.gov as NCT02126215. Twelve patients were studied. Pre-operative psychiatric symptom measures and neuropsychological testing preceded MRI featuring a BOLD MRI CO2 stress test whereby BOLD scans were conducted while exposing participants to a rigorously controlled CO2 stimulus. During surgery the patient had hemodynamics and end-tidal gases downloaded at 0.5 hz. Post-operatively, the presence of POD and POD severity was comprehensively assessed using the Confusion Assessment Measure –Severity (CAM-S scoring instrument on days 0 (surgery through post-operative day 5, and patients were followed up at least 1 month post-operatively.Results: Six of 12 patients had no evidence of POD (non-POD. Three patients had POD and 3 had clinically significant confusional states (referred as subthreshold POD; ST-POD (score ≥ 5/19 on the CAM-S. Average severity for delirium was 1.3 in the non-POD group, 3.2 in ST-POD, and 6.1 in POD (F-statistic = 15.4, p < 0.001. Depressive symptoms, and cognitive measures of semantic fluency and executive functioning/processing speed were significantly associated with POD. Second level analysis revealed an increased inverse BOLD responsiveness to CO2 pre-operatively in ST-POD and marked increase in the POD groups when compared to the non-POD group. An association was also noted for

    We present the pathological findings in a case of acquired immunodeficiency syndrome (AIDS) in a patient with no known risk factor. Postmortem examination showed klebsiella lung abscess, generalised cytomegalovirus infection, cerebral toxoplasmosis, and a primary cerebral lymphoma. An additional feature was the presence of dilatation of the intrahepatic large bile ducts in association with an atypical distribution of cytomegalovirus. The relation between this case and previously reported cases of AIDS is discussed.

    Pediatric supracondylar humerus fractures are common injuries that are often treated surgically with closed reduction and percutaneous pinning. Although surgical-site infections are rare, postoperative antibiotics are frequently administered without evidence or guidelines for their use. With the increasing prevalence of antibiotic-resistant organisms and heightened focus on health care costs, appropriate and evidence-based use of antibiotics is needed. We hypothesized that postoperative antibiotic administration would not decrease the rate of surgical-site infection. A billing query identified 951 patients with operatively treated supracondylar humerus fractures at our institution over a 15-year period. Records were reviewed for demographic data, perioperative antibiotic use, and the presence of surgical-site infection. Exclusion criteria were open fractures, open reduction, pathologic fractures, metabolic bone disease, the presence of other injuries that required operative treatment, and follow-up <2 weeks after pin removal. χ and Fisher exact test were used to compare antibiotic use to the incidence of surgical-site infection. Six hundred eighteen patients met our inclusion criteria. Two hundred thirty-eight patients (38.5%) received postoperative antibiotics. Eleven surgical-site infections were identified for an overall rate of 1.8%. The use of postoperative antibiotics was not associated with a lower rate of surgical-site infection (P=0.883). Patients with a type III fracture (P<0.001), diminished preoperative vascular (P=0.001) and neurological status (P=0.019), and postoperative hospital admission (P<0.001) were significantly more likely to receive postoperative antibiotics. Administration of postoperative antibiotics after closed reduction and percutaneous pinning of pediatric supracondylar humerus fractures does not decrease the rate of surgical-site infection.

    Pancreatic fistula (PF) remains the most challenging complication after pancreaticoduodenectomy (PD). The purpose of this study was to identify the risk factors of PF and delineate its impact on patient outcomes. We retrospectively reviewed clinical data of 532 patients who underwent PD and divided them into PF group and no PF group. Risk factors and outcomes of PF following PD were examined. PF was found in 65 (12.2%) cases, of whom 11 were classified into ISGPF grade A, 42 grade B, and 12 grade C. Clinically serious postoperative complications in the PF versus no PF group were mortality, abdominal bleeding, bile leak, intra-abdominal abscess and pneumonia. Univariate and multivariate analysis showed that blood loss ≥ 500 ml, pancreatic duct diameter ≤ 3 mm and pancreaticojejunostomy type were independent risk factors of PF after PD. Blood loss ≥ 500 ml, pancreatic duct diameter ≤ 3 mm and pancreatico-jejunostomy type were independent risk factors of PF after PD. PF was related with higher mortality rate, longer hospital stay, and other complications.

    In 1983, Michael W. Vannier and Jeffrey L. Marsh developed a computer method that reconstructs three-dimensional images from high-resolution CT-scan series of the facial skeleton. This method has been applied to craniofacial anomalies, basal encephalocele, and other skeletal pathologies. In this study, the postoperative assessment of craniofacial surgical results has been accomplished using 3D-CT techniques in craniosynostosis. The results are as follows: (1) Postoperative 3D-CTs reveal the bony anatomical details corrected by the craniofacial surgery more precisely and more stereographically than do conventional radiological techniques. (2) Secondary changes in the cranium after the surgery, such as reossification at the area of osteotomies or postoperative asymmetric skull deformities, are more early detected by the 3D-CT imaging technique than by a craniogram. (3) In 3D-CT images, internal views of the skull, such mid-sagittal, rear internal, or top axial views of the intracranial skull base, are most useful in postoperative assessments of the surgical results and of postoperative secondary changes in the cranium. Based on our experience, we expect that 3D-CT imaging techniques will become more important in the management of craniosynostosis.

    This study was conducted to determine the effect of age at diagnosis and length of ganglionated bowel resected on postoperative Hirschsprung-associated enterocolitis (HAEC). Children who underwent endorectal pull-through (ERPT) between January 1993 and December 2004 were retrospectively reviewed. t Test, analysis of variance, Kaplan-Meier, and Cox's proportional hazards analyses were performed. Fifty-two children with Hirschsprung disease (median age, 25 days; range, 2 days-16 years) were included. Nineteen (37%) had admissions for HAEC. Proportional hazards regression showed that HAEC admissions decreased by 30% with each doubling of age at diagnosis (P = .03) and increased 9-fold when postoperative stricture was present (P 5 cm]). No significant difference in the number of HAEC admissions during initial 2 years post-ERPT was seen between groups A (n = 18) and B (n = 18). The study had a power of 0.8 to detect a difference of 1 admission over 2 years. Children diagnosed with Hirschsprung disease at younger ages are at a greater risk for postoperative enterocolitis. Excising a longer margin of ganglionated bowel (>5 cm) does not seem to be beneficial in decreasing HAEC admissions.

    To determine the impact of preoperative serum creatinine level in non-dialyzable patients on postoperative morbidity and mortality. This is a prospective study, where serum creatinine was used to give primary assessment on renal function status preoperatively. This study includes 1,033 patients, who underwent coronary artery bypass grafting, or valve(s) operations. The study took place at Al-Hada Military Hospital, Taif, Kingdom of Saudi between May 2008 and January 2012. Data were statistically analyzed using Chi square (x2) test and multivariable logistic regression, to evaluate the postoperative morbidity and mortality risks associated with low serum creatinine levels. Postoperative mortality increased with high serum creatinine level >1.8 mg/dL (pcreatinine level of more than 1.8 mg/dL was associated with increased risk of re-operation for bleeding, postoperative renal failure, prolonged ventilatory support, ICU stay, and total hospital stay. Perioperative serum creatinine is strongly related to post operative morbidity and mortality in open heart surgery. High serum creatinine in non-dialyzable patients can predict the increased morbidity and mortality after cardiac operations.

    INTRODUCTION Between 4% and 13% of patients with operable pancreatic malignancy are found unresectable at the time of surgery. Double bypass is a good option for fit patients but it is associated with high risk of postoperative complications. The aim of this study was to identify pre-operatively which patients undergoing double bypass are at high risk of complications and to assess their long-term outcome. METHODS Of the 576 patients undergoing pancreatic resections between 2006 and 2011, 50 patients who underwent a laparotomy for a planned pancreaticoduodenectomy had a double bypass procedure for inoperable disease. Demographic data, risk factors for postoperative complications and pre-operative anaesthetic assessment data including the Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) and cardiopulmonary exercise testing (CPET) were collected. RESULTS Fifty patients (33 men and 17 women) were included in the study. The median patient age was 64 years (range: 39–79 years). The complication rate was 50% and the in-hospital mortality rate was 4%. The P-POSSUM physiology subscore and low anaerobic threshold at CPET were significantly associated with postoperative complications (p=0.005 and p=0.016 respectively) but they were unable to predict them. Overall long-term survival was significantly shorter in patients with postoperative complications (9 vs 18 months). Postoperative complications were independently associated with poorer long-term survival (p=0.003, odds ratio: 3.261). CONCLUSIONS P-POSSUM and CPET are associated with postoperative complications but the possibility of using them for risk prediction requires further research. However, postoperative complications following double bypass have a significant impact on long-term survival and this type of surgery should therefore only be performed in specialised centres.

    Human papillomavirus-positive oropharyngeal squamous cell carcinoma is increasing in incidence worldwide. Current treatments are associated with high survival rates but often result in significant long-term toxicities. In particular, long-term dysphagia has a negative impact on patient quality of life and health. The aim of PATHOS is to determine whether reducing the intensity of adjuvant treatment after minimally invasive transoral surgery in this favourable prognosis disease will result in better long-term swallowing function whilst maintaining excellent disease-specific survival outcomes. The study is a multicentre phase II/III randomised controlled trial for patients with biopsy-proven Human papillomavirus-positive oropharyngeal squamous cell cancer staged T1-T3 N0-N2b with a primary tumour that is resectable via a transoral approach. Following transoral surgery and neck dissection, patients are allocated into three groups based on pathological risk factors for recurrence. Patients in the low-risk pathology group will receive no adjuvant treatment, as in standard practice. Patients in the intermediate-risk pathology group will be randomised to receive either standard dose post-operative radiotherapy (control) or reduced dose radiotherapy. Patients in the high-risk pathology group will be randomised to receive either post-operative chemoradiotherapy (control) or radiotherapy alone. The primary outcome of the phase II study is patient reported swallowing function measured using the MD Anderson Dysphagia Inventory score at 12 months post-treatment. If the phase II study is successful, PATHOS will proceed to a phase III non-inferiority trial with overall survival as the primary endpoint. PATHOS is a prospective, randomised trial for Human papillomavirus-positive oropharyngeal cancer, which represents a different disease entity compared with other head and neck cancers. The trial aims to demonstrate that long-term dysphagia can be lessened by reducing the intensity

    Pathological femoral head and neck fractures are commonly treated by arthroplasty. Treatment options for the trochanteric region or below are not clearly defined. The purpose of this retrospective, comparative, double-centre study was to analyse survival and influences on outcome according to the surgical technique used to treat pathological proximal femoral fractures, excluding fractures of the femoral head and neck. Fifty-nine patients with 64 fractures were operated up on between 1998 and 2004 in two tertiary referral centres and divided into two groups. One group (S, n = 33) consisted of patients who underwent intramedullary nailing alone, and the other group (R, n = 31) consisted of patients treated by metastatic tissue resection and reconstruction by means of different implants. Median survival was 12.6 months with no difference between groups. Surgical complications were higher in the R group (n = 7) vs. the S group (n = 3), with no statistically significant difference. Patients with surgery-related complications had a higher survival rate (p = 0.049), as did patients with mechanical implant failure (p = 0.01). Survival scoring systems did not correlate with actual survival. Resection of metastases in patients with pathological fractures of the proximal femur, excluding femoral head and neck fractures, has no influence on survival. Patients with long postoperative survival prognosis are at risk of implant-related complications.

    As a rule, postoperative imaging is carried out after spinal interventions to document the exact position of the implant material. Imaging is absolutely necessary when new clinical symptoms occur postoperatively. In this case a rebleeding or an incorrect implant position abutting a root or the spinal cord must be proven. In addition to these immediately occurring postoperative clinical symptoms, there are a number of complications that can occur several days, weeks or even months later. These include the failed back surgery syndrome, implant loosening or breakage of the material and relapse of a disc herniation and spondylodiscitis. In addition to knowledge of the original clinical symptoms, it is also important to know the operation details, such as the access route and the material used. In almost all postoperative cases, imaging with contrast medium administration and corresponding correction of artefacts by the implant material, such as the dual energy technique, correction algorithms and the use of special magnetic resonance (MR) sequences are necessary. In order to correctly assess the postoperative imaging, knowledge of the surgical procedure and the previous clinical symptoms are mandatory besides special computed tomography (CT) techniques and MR sequences.

    Colorectal cancer surgery is associated with a high incidence of post-operative infections, the outcome of which may be improved if diagnosed and treated early enough. We compared white blood cell (WBC) count, C-reactive protein (CRP), and procalcitonin (PCT) as predictors of post-operative infections and analyzed their impact on long-term survival. This retrospective study included 186 patients undergoing colorectal surgery. Post-operative values of WBC, CRP, and PCT were analyzed by the receiver operating characteristic (ROC) analysis. We followed infections 30 d after the surgery. A five-year survival was analyzed by Kaplan-Meier method and prognostic factors by Cox regression model. Fifty-five patients (29.5%) developed post-operative infection, the most frequent of which was surgical site infection (SSI). C-reactive protein on post-operative day three and PCT on post-operative day two demonstrated the highest diagnostic accuracy for infection (area under the curve [AUC] 0.739 and 0.735). C-reactive protein on post-operative day three was an independent predictor of infection. Five-year survival was higher in the non-infected group (70.8%), compared with the infected group (52.1%). The worst survival (40.9%) was identified in patients with organ/space SSI. Post-operative infection and tumor stage III-IV were independent predictors of a worse five-year survival. C-reactive protein on post-operative day three and PCT on post-operative day two may be early predictors of infection after colorectal cancer surgery. Post-operative infections in particular organ/space SSI have a negative impact on long-term survival.

    Few studies have evaluated the risk of postoperative colorectal neoplasms stratified by the nature of primary colorectal cancer (CRC). In this study, we revealed it on the basis of the microsatellite (MS) status of primary CRC. We retrospectively reviewed 338 patients with CRC and calculated the risk of neoplasms during postoperative surveillance colonoscopy in association with the MS status of primary CRC. A propensity score method was applied. We identified a higher incidence of metachronous rectal neoplasms after the resection of MS stable CRC than MS instable CRC (adjusted HR 5.74, p=0.04). We also observed a higher incidence of colorectal tubular adenoma in patients with MSS CRC (adjusted hazard ratio 7.09, pcolorectal cancer influenced the risk of postoperative colorectal neoplasms.

    Purpose: The postoperative evaluation of scoliosis patients undergoing corrective treatment is an important task to assess the strategy of the spinal surgery. Using accurate 3D geometric models of the patient’s spine is essential to measure longitudinal changes in the patient’s anatomy. On the other hand, reconstructing the spine in 3D from postoperative radiographs is a challenging problem due to the presence of instrumentation (metallic rods and screws) occluding vertebrae on the spine. Methods: This paper describes the reconstruction problem by searching for the optimal model within a manifold space of articulated spines learned from a training dataset of pathological cases who underwent surgery. The manifold structure is implemented based on a multilevel manifold ensemble to structure the data, incorporating connections between nodes within a single manifold, in addition to connections between different multilevel manifolds, representing subregions with similar characteristics. Results: The reconstruction pipeline was evaluated on x-ray datasets from both preoperative patients and patients with spinal surgery. By comparing the method to ground-truth models, a 3D reconstruction accuracy of 2.24 ± 0.90 mm was obtained from 30 postoperative scoliotic patients, while handling patients with highly deformed spines. Conclusions: This paper illustrates how this manifold model can accurately identify similar spine models by navigating in the low-dimensional space, as well as computing nonlinear charts within local neighborhoods of the embedded space during the testing phase. This technique allows postoperative follow-ups of spinal surgery using personalized 3D spine models and assess surgical strategies for spinal deformities.

    Full Text Available Elderly surgical patients frequently experience postoperative delirium (POD and the subsequent development of postoperative cognitive dysfunction (POCD. Clinical features include deterioration in cognition, disturbance in attention and reduced awareness of the environment and result in higher morbidity, mortality and greater utilization of social financial assistance. The aging Western societies can expect an increase in the incidence of POD and POCD. The underlying pathophysiological mechanisms have been studied on the molecular level albeit with unsatisfying small research efforts given their societal burden. Here, we review the known physiological and immunological changes and genetic risk factors, identify candidates for further studies and integrate the information into a draft network for exploration on a systems level. The pathogenesis of these postoperative cognitive impairments is multifactorial; application of integrated systems biology has the potential to reconstruct the underlying network of molecular mechanisms and help in the identification of prognostic and diagnostic biomarkers.

    Whole mount processing is more resource intensive than routine systematic sampling of radical retropubic prostatectomy specimens. We compared whole mount and systematic sampling for detecting pathological outcomes, and compared the prognostic value of pathological findings across pathological methods. We included men (608 whole mount and 525 systematic sampling samples) with no prior treatment who underwent radical retropubic prostatectomy at Vanderbilt University Medical Center between January 2000 and June 2008. We used univariate and multivariate analysis to compare the pathological outcome detection rate between pathological methods. Kaplan-Meier curves and the log rank test were used to compare the prognostic value of pathological findings across pathological methods. There were no significant differences between the whole mount and the systematic sampling groups in detecting extraprostatic extension (25% vs 30%), positive surgical margins (31% vs 31%), pathological Gleason score less than 7 (49% vs 43%), 7 (39% vs 43%) or greater than 7 (12% vs 13%), seminal vesicle invasion (8% vs 10%) or lymph node involvement (3% vs 5%). Tumor volume was higher in the systematic sampling group and whole mount detected more multiple surgical margins (each p systematic sampling yield similar pathological information. Each method stratifies patients into comparable risk groups for biochemical recurrence. Thus, while whole mount is more resource intensive, it does not appear to result in improved detection of clinically important pathological outcomes or prognostication.

    We identified factors associated with early and late postoperative seizure control in patients with supratentorial meningioma plus preoperative seizures. In this retrospective study, univariate analysis and multivariate logistic regression analysis compared 24 clinical variables according to the occurrence of early (≤1 week) or late (>1 week) postoperative seizures. Sixty-two of 97 patients (63.9 %) were seizure free for the entire postoperative follow-up period (29.5 ± 11.8 months), while 13 patients (13.4 %) still had frequent seizures at the end of follow-up. Fourteen of 97 patients (14.4 %) experienced early postoperative seizures, and emergence of new postoperative neurological deficits was the only significant risk factor (odds ratio = 7.377). Thirty-three patients (34.0 %) experienced late postoperative seizures at some time during follow-up, including 12 of 14 patients with early postoperative seizures. Associated risk factors for late postoperative seizures included tumor progression (odds ratio = 7.012) and new permanent postoperative neurological deficits (odds ratio = 4.327). Occurrence of postoperative seizures in patients with supratentorial meningioma and preoperative seizure was associated with new postoperative neurological deficits. Reduced cerebral or vascular injury during surgery may lead to fewer postoperative neurological deficits and better seizure outcome.

    The assessment of bone healing and loosening of endoprosthesis material was long the primary indication for postoperative projection radiography and CT imaging of the hip joint following trauma and endoprosthesis implantation. With the increasing number of joint-preserving surgery, e. g. of surgical hip luxation and hip arthroscopy for the treatment of femoroacetabular impingement (FAI), high-resolution imaging of intra-articular pathologies before and after surgery has become increasingly important. In this review article, diagnostic imaging of the hip joint is presented following common trauma surgery and orthopedic surgery interventions. The imaging modalities of projection radiography, CT and MRI including direct MR-arthrography are discussed with regard to their diagnostic capability in the postoperative assessment of the hip joint. Among others topics, imaging is discussed following hip arthroplasty, following surgical hip luxation and arthroscopic interventions for the treatment of FAI, as well as following core decompression for avascular necrosis of the femoral head. Moreover, orthopedic interventions of the hip joint in children and adolescents are presented and the dedicated reporting of postoperative imaging is outlined.

    Purpose: Although orthopedic stabilization is frequently performed for pathological fractures caused by metastatic disease, no data is available to support the value of postoperative radiation therapy (S+RT) in this setting. Methods and Materials: We reviewed 64 orthopedic stabilization procedures in 60 consecutive patients with metastatic disease to previously unirradiated weight-bearing bones with pathological or impending pathological fracture (femur 91%). Thirty-five sites that received adjuvant S+RT were compared to 29 sites that were treated with surgery alone (SA). Many potential prognostic variables were evaluated. Endpoints were: functional status (FS) of the extremity (1 = normal pain free use; 2 = normal use with pain, 3 significantly limited use; 4 = nonfunctional extremity), subsequent orthopedic procedures to the same site, and survival following surgery. Results: At the univariate level, S+RT (p = 0.02) and prefracture FS (p 0.04) were the only significant predictors of patients achieving an FS of 1 or 2 after surgery. On multivariate analysis, only postoperative RT was significantly (p = 0.02) associated with attaining FS of 1 or 2 after surgery. The predicted probability of achieving FS 1 or 2 at any time was 53% for S+RT vs. 11.5% or SA (multiple logistic regression, p < 0.01). Evaluation of FS following surgery revealed that S+RT group had significantly better function in the 1-3, 3-6, and 6-12 month postoperative periods (chi-square, p < 0.04 for each time period). Second orthopedic procedures to the same site were more common in the SA group than the S+RT group (log rank, p = 0.03). Actuarial median survival of S group was 3.3 months compared with 12.4 months for the S+RT group (log rank, p = 0.02), confirming the beneficial association with survival shown by the multivariate Cox regression analysis (p = 0.025). Conclusion: Although this retrospective study is subject to possible biases, several analyses adjusting for numerous prognostic

    Background: Preoperative anemia may affect postoperative mortality and morbidity following elective cranial operations. Methods: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was used to identify elective cranial neurosurgical cases (2006-2012). Morbidity was defined as wound infection, systemic infection, cardiac, respiratory, renal, neurologic, and thromboembolic events, and unplanned returns to the operating room. For 30-day postoperative mortality and morbidity, adjusted odds ratios (ORs) were estimated with multivariable logistic regression. Results: Of 8015 patients who underwent elective cranial neurosurgery, 1710 patients (21.4%) were anemic. Anemic patients had an increased 30-day mortality of 4.1% versus 1.3% in non-anemic patients (P neurosurgery was independently associated with an increased risk of 30-day postoperative mortality and morbidity when compared to non-anemic patients. A hematocrit level below 33% (Hgb 11 g/dl) was associated with a significant increase in postoperative morbidity. PMID:25422784

    Perioperative antibiotic prophylaxis in patients undergoing surgery for maxillofacial fractures is standard practice. However, the use of postoperative antibiotic prophylaxis remains controversial. This systematic review and meta-analysis sought to evaluate the effect of postoperative antibiotic therapy on the incidence of surgical site infection (SSI) in patients with maxillofacial fractures. MEDLINE, Embase, and the Cochrane Library were searched from inception through October 2017. Randomized controlled trials (RCTs) and cohort studies evaluating the efficacy of pre-, peri-, and postoperative antibiotic prophylaxis in preventing SSI in maxillofacial fractures were included. Data were extracted from studies using a standardized data collection form, with two reviewers independently performing extraction and quality assessment for each study. Risk ratios (RRs) for SSI were pooled using a random-effects model. Among 2,150 potentially eligible citations, 13 studies met inclusion criteria and provided data to be included in a meta-analysis. The addition of postoperative antibiotic prophylaxis to a standard preoperative and/or perioperative antibiotic regimen showed no significant difference in the risk of SSI (RR = 1.11 [95% CI: 0.86-1.44], P > .1). There were also no differences in the risk of SSI when restricting the analysis to mandibular fractures (eight studies, RR = 1.22 [95% CI: 0.92-1.62]) or open surgical techniques (eight studies, RR = 1.02 [95% CI: 0.62-1.67]). A sensitivity analysis did not find any significant differences in risk when restricting to RCTs (seven trials, RR = 1.00 [95% CI: 0.61-1.67]) or cohort studies (six studies, RR = 1.21 [95% CI: 0.89-1.63]). Our findings, along with the available evidence, does not support the routine use of postoperative antibiotic prophylaxis in patients with maxillofacial fractures. Avoiding the unnecessary use of antibiotic therapy in the postoperative period could have important

    We aimed to investigate eating disorder pathology in German elite adolescent athletes. Evidence suggests that eating disorder pathology is more common in adult elite sports, especially in female athletes and in sports emphasizing leanness. There is a scarcity of studies in elite adolescent athletes who are in a vulnerable developmental stage and are affected by general as well as sport-specific risk factors. Our data was derived from the German Young Olympic Athletes' Lifestyle and Health Management Study (GOAL) which conducted a survey in 1138 elite adolescent athletes. In this sample, we assessed body weight, weight control behavior, body acceptance and screened overall for core symptoms of eating disorders, depression and anxiety. We performed a tree analysis to identify high risk groups for eating disorder pathology. High risk groups comprised (a) athletes competing in weight dependent sports, and among athletes competing in disciplines other than weight dependent sports (b) athletes who are high on negative affectivity, (c) female athletes and (d) male athletes competing in endurance, technical or power sports. Athletes competing in weight dependent disciplines reported wide spread use of compensatory behaviors to influence body weight. Athletes reporting eating disorder pathology showed higher levels of depression and anxiety than athletes without eating disorder pathology. Increased psychosocial burden in athletes with eating disorder pathology suggests that eating disorder symptoms should not be accepted as an unproblematic and functional part of elite sports. The prevention and management of eating disorder pathology is especially important in weight dependent sports. © 2016 Wiley Periodicals, Inc.

    OBJECTIVE Depression is the most prevalent affective disorder in the US, and patients with spinal deformity are at increased risk. Postoperative delirium has been associated with inferior surgical outcomes, including morbidity and mortality. The relationship between depression and postoperative delirium in patients undergoing spine surgery is relatively unknown. The aim of this study was to determine if depression is an independent risk factor for the development of postoperative delirium in patients undergoing decompression and fusion for deformity. METHODS The medical records of 923 adult patients (age ≥ 18 years) undergoing elective spine surgery at a single major academic institution from 2005 through 2015 were reviewed. Of these patients, 255 (27.6%) patients had been diagnosed with depression by a board-certified psychiatrist and constituted the Depression group; the remaining 668 patients constituted the No-Depression group. Patient demographics, comorbidities, and intra- and postoperative complication rates were collected for each patient and compared between groups. The primary outcome investigated in this study was rate of postoperative delirium, according to DSM-V criteria, during initial hospital stay after surgery. The association between depression and postoperative delirium rate was assessed via multivariate logistic regression analysis. RESULTS Patient demographics and comorbidities other than depression were similar in the 2 groups. In the Depression group, 85.1% of the patients were taking an antidepressant prior to surgery. There were no significant between-group differences in intraoperative variables and rates of complications other than delirium. Postoperative complication rates were also similar between the cohorts, including rates of urinary tract infection, fever, deep and superficial surgical site infection, pulmonary embolism, deep vein thrombosis, urinary retention, and proportion of patients transferred to the intensive care unit.

    To evaluate the postoperative outcomes of cataract eyes complicated with coexisting ocular pathologies that underwent implantation of a refractive multifocal intraocular lens (MIOL) with a surface-embedded near section. LENTIS MPlus (Oculentis GmbH) refractive MIOLs were implanted in 15 eyes with ocular pathologies other than cataract (ie, six high-myopia eyes with an axial length longer than 28 mm, two fundus albipunctatus eyes, two branch retinal-vein occlusion eyes, four glaucoma eyes (one with high myopia), and two keratoconus eyes). Uncorrected or corrected distance and near visual acuity (VA) (UDVA, UNVA, CDVA, and CNVA), contrast sensitivity, and defocus curve were measured at 1 day and 6 months postoperatively, and each patient completed a 6-month postoperative questionnaire regarding vision quality and eyeglass use. Thirteen eyes (87%) registered 0 or better in CDVA and 12 eyes (73%) registered better than 0 in CNVA. Contrast sensitivity in the eyes of all patients was comparable to that of normal healthy subjects. No patient required eyeglasses for distance vision, but three patients (20%) required them for near vision. No patient reported poor or very poor vision quality. With careful case selection, sectorial refractive MIOL implantation is effective for treating cataract eyes complicated with ocular pathologies.

    Anastomotic leakage (AL) is one of the most devastating complications after rectal cancer surgery. The double stapling technique has greatly facilitated intestinal reconstruction especially for anastomosis after low anterior resection (LAR). Risk factor analyses for AL after open LAR have been widely reported. However, a few studies have analyzed the risk factors for AL after laparoscopic LAR. Laparoscopic rectal surgery provides an excellent operative field in a narrow pelvic space, and enables total mesorectal excision surgery and preservation of the autonomic nervous system with greater precision. However, rectal transection using a laparoscopic linear stapler is relatively difficult compared with open surgery because of the width and limited performance of the linear stapler. Moreover, laparoscopic LAR exhibits a different postoperative course compared with open LAR, which suggests that the risk factors for AL after laparoscopic LAR may also differ from those after open LAR. In this review, we will discuss the risk factors for AL after laparoscopic LAR.

    Despite limited indications, preoperative stress testing is often used prior to non-cardiac surgery. Patient-level analyses of stress testing and outcomes are limited by case mix and selection bias. Therefore, we sought to describe facility-level rates of preoperative stress testing for non-cardiac surgery, and to determine the association between facility-level preoperative stress testing and postoperative major adverse cardiac events (MACE). We identified patients undergoing non-cardiac surgery within 2 years of percutaneous coronary intervention in the Veterans Affairs (VA) Health Care System, from 2004 to 2011, facility-level rates of preoperative stress testing and postoperative MACE (death, myocardial infarction (MI) or revascularisation within 30 days). We determined risk-standardised facility-level rates of stress testing and postoperative MACE, and the relationship between facility-level preoperative stress testing and postoperative MACE. Among 29 937 patients undergoing non-cardiac surgery at 131 VA facilities, the median facility rate of preoperative stress testing was 13.2% (IQR 9.7%-15.9%; range 6.0%-21.5%), and 30-day postoperative MACE was 4.0% (IQR 2.4%-5.4%). After risk standardisation, the median facility-level rate of stress testing was 12.7% (IQR 8.4%-17.4%) and postoperative MACE was 3.8% (IQR 2.3%-5.6%). There was no correlation between risk-standardised stress testing and composite MACE at the facility level (r=0.022, p=0.81), or with individual outcomes of death, MI or revascularisation. In a national cohort of veterans undergoing non-cardiac surgery, we observed substantial variation in facility-level rates of preoperative stress testing. Facilities with higher rates of preoperative stress testing were not associated with better postoperative outcomes. These findings suggest an opportunity to reduce variation in preoperative stress testing without sacrificing patient outcomes. © Article author(s) (or their employer(s) unless otherwise

    To determine if there is a relationship between the risk of postoperative complications and the nonclinical hospital characteristics of bed size, ownership structure, relative urbanicity, regional location, teaching status, and area income status. This study involved a secondary analysis of 2006 administrative hospital data from a number of U.S. states. This data, gathered annually by the Agency for Healthcare Research and Quality (AHRQ) via the National Inpatient Sample (NIS) Healthcare Utilization Project (HCUP), was analyzed using probit regressions to measure the effects of several nonclinical hospital categories on seven diagnostic groupings. The study model included postoperative complications as well as additional potentially confounding variables. The results showed mixed outcomes for each of the hospital characteristic groupings. Subdividing these groupings to correspond with the HCUP data analysis allowed a greater understanding of how hospital characteristics' may affect postoperative outcomes. Nonclinical hospital characteristics do affect the various postoperative complications, but they do so inconsistently.

    The aim was to investigate whether 2 weeks of inspiratory muscle training (IMT) could preserve respiratory muscle strength in high-risk patients referred for pulmonary resection on the suspicion of or confirmed lung cancer. Secondarily, we investigated the effect of the intervention on the incidence of postoperative pulmonary complications. The study was a single-centre, parallel-group, randomized trial with assessor blinding and intention-to-treat analysis. The intervention group (IG, n = 34) underwent 2 weeks of postoperative IMT twice daily with 2 × 30 breaths on a target intensity of 30% of maximal inspiratory pressure, in addition to standard postoperative physiotherapy. Standard physiotherapy in the control group (CG, n = 34) consisted of breathing exercises, coughing techniques and early mobilization. We measured respiratory muscle strength (maximal inspiratory/expiratory pressure, MIP/MEP), functional performance (6-min walk test), spirometry and peripheral oxygen saturation (SpO2), assessed the day before surgery and again 3-5 days and 2 weeks postoperatively. Postoperative pulmonary complications were evaluated 2 weeks after surgery. The mean age was 70 ± 8 years and 57.5% were males. Thoracotomy was performed in 48.5% (n = 33) of cases. No effect of the intervention was found regarding MIP, MEP, lung volumes or functional performance at any time point. The overall incidence of pneumonia was 13% (n = 9), with no significant difference between groups [IG 6% (n = 2), CG 21% (n = 7), P = 0.14]. An improved SpO2 was found in the IG on the third and fourth postoperative days (Day 3: IG 93.8 ± 3.4 vs CG 91.9 ± 4.1%, P = 0.058; Day 4: IG 93.5 ± 3.5 vs CG 91 ± 3.9%, P = 0.02). We found no association between surgical procedure (thoracotomy versus thoracoscopy) and respiratory muscle strength, which was recovered in both groups 2 weeks after surgery. Two weeks of additional postoperative IMT, compared with standard physiotherapy alone, did not preserve

    Purpose To investigate the initial clinical value of fluorine 18 ( 18 F) fluorocholine (FCH) dynamic positron emission tomography (PET)/magnetic resonance (MR) imaging by comparing its parameters with clinical-pathologic findings in patients with newly diagnosed intermediate- to high-risk prostate cancer (PCa) who plan to undergo radical prostatectomy. Materials and Methods The institutional review board approved the study protocol, and informed written consent was obtained from all subjects for this HIPAA-compliant study. Twelve men (mean age ± standard deviation, 61.7 years ± 8.4; range, 46-74 years) with untreated intermediate- to high-risk PCa characterized according to Cancer of the Prostate Risk Assessment (CAPRA) underwent preoperative FCH dynamic PET/MR imaging followed by radical prostatectomy between April and November 2015. PET/MR imaging parameters including average and maximum K1 (delivery rate constant) and standardized uptake values (SUVs) and Prostate Imaging Reporting and Data System (PI-RADS) version 2 scores were measured and compared with clinical-pathologic characteristics. For statistical analysis, the Spearman rank correlation and Mann-Whitney U tests were performed. Results Of the PET parameters, maximum SUV of primary tumors showed significant correlations with several clinical-pathologic parameters including serum prostate-specific antigen level (ρ = 0.71, P = .01), pathologic stage (ρ = 0.59, P = .043), and postsurgical CAPRA score (ρ = 0.72, P = .008). The overall PI-RADS score showed significant correlations with pathologic tumor volume (ρ = 0.81, P PET and MR imaging showed improved sensitivity (88%) for prediction of pathologic extraprostatic extension compared with that with MR imaging (50%) and PET (75%) performed separately. Conclusion Maximum SUVs and PI-RADS scores from FCH PET/MR imaging show good correlation with clinical-pathologic characteristics, such as postsurgical CAPRA score, which are related to prognosis in

    Pathological gambling is a behavioural addiction with negative economic, social, and psychological consequences. Identification of contributing genes and pathways may improve understanding of aetiology and facilitate therapy and prevention. Here, we report the first genome-wide association study of pathological gambling. Our aims were to identify pathways involved in pathological gambling, and examine whether there is a genetic overlap between pathological gambling and alcohol dependence. Four hundred and forty-five individuals with a diagnosis of pathological gambling according to the Diagnostic and Statistical Manual of Mental Disorders were recruited in Germany, and 986 controls were drawn from a German general population sample. A genome-wide association study of pathological gambling comprising single marker, gene-based, and pathway analyses, was performed. Polygenic risk scores were generated using data from a German genome-wide association study of alcohol dependence. No genome-wide significant association with pathological gambling was found for single markers or genes. Pathways for Huntington's disease (P-value=6.63×10(-3)); 5'-adenosine monophosphate-activated protein kinase signalling (P-value=9.57×10(-3)); and apoptosis (P-value=1.75×10(-2)) were significant. Polygenic risk score analysis of the alcohol dependence dataset yielded a one-sided nominal significant P-value in subjects with pathological gambling, irrespective of comorbid alcohol dependence status. The present results accord with previous quantitative formal genetic studies which showed genetic overlap between non-substance- and substance-related addictions. Furthermore, pathway analysis suggests shared pathology between Huntington's disease and pathological gambling. This finding is consistent with previous imaging studies.

    It is unclear whether epidermal growth factor receptor (EGFR) mutation status is a risk factor for postoperative recurrence of surgically resected lung adenocarcinoma (ADC). Therefore, we conducted a multi-institutional study employing matched-pair analysis to compare recurrence-free survival (RFS) and overall survival (OS) of patients with lung ADC according to EGFR mutation status. We collected the records of 909 patients who underwent surgical resection for lung ADC between 2005 and 2012 at five participating institutions and were also examined their EGFR mutation status. For each patient with an EGFR mutation, we selected one with the wild-type EGFR sequence and matched them according to institution, age, gender, smoking history, pathological stage (pStage), and adjuvant treatment. We compared RFS and OS of the matched cohort. The patients were allocated into groups (n=181 each) with mutated or wild-type EGFR sequences. Both cohorts had identical characteristics as follows: institution, median age (68 years), men (85, 47%), ever smokers (77, 43%), and pStage (IA, 108, 60%; IB, 48, 27%; II, 14, 8%; III, 11, 6%). The 3- and 5-year RFS rates of patients with mutated or wild-type EGFR sequence were 79%, 68% and 77%, 68%, respectively (p=0.557). The respective OS rates were 92%, 81%, and 89%, 79% (p=0.574). Matched-pair and multi-institutional analysis reveals that an EGFR mutation was not a significant risk factor for recurrence of patients with surgically resected lung adenocarcinoma.

    Full Text Available Dementia drug development aims to modulate pathological processes that cause clinical syndromes. Population data (epidemiological neuropathology will help to model and predict the potential impact of such therapies on dementia burden in older people. Presently this can only be explored through post mortem findings. We report the attributable risks (ARs for dementia at death for common age-related degenerative and vascular pathologies, and other factors, in the MRC Cognitive Function and Ageing Study (MRC CFAS.A multicentre, prospective, longitudinal study of older people in the UK was linked to a brain donation programme. Neuropathology of 456 consecutive brain donations assessed degenerative and vascular pathologies. Logistic regression modelling, with bootstrapping and sensitivity analyses, was used to estimate AR at death for dementia for specific pathologies and other factors. The main contributors to AR at death for dementia in MRC CFAS were age (18%, small brain (12%, neocortical neuritic plaques (8% and neurofibrillary tangles (11%, small vessel disease (12%, multiple vascular pathologies (9%, and hippocampal atrophy (10%. Other significant factors include cerebral amyloid angiopathy (7% and Lewy bodies (3%.Such AR estimates cannot be derived from the living population; rather they estimate the relative contribution of specific pathologies to dementia at death. We found that multiple pathologies determine the overall burden of dementia. The impact of therapy targeted to a specific pathology may be profound when the dementia is relatively "pure," but may be less impressive for the majority with mixed disease, and in terms of the population. These data justify a range of strategies, and combination therapies, to combat the degenerative and vascular determinants of cognitive decline and dementia.

    Predicting patients' risk for hypocalcemia after thyroidectomy may allow for same-day discharge. This study was designed to compare postoperative intact parathyroid hormone (IPTH) alone with percentage change in IPTH (IPTH gradient) in predicting post-thyroidectomy hypocalcemia. Retrospective cohort study. Patients undergoing total thyroidectomy by the senior author from May 2015 to May 2016 were included. Serum IPTH was measured preoperatively and 1 hour postoperatively, and IPTH gradient was calculated. Postoperative hypocalcemia was mild (≥8.0, gradient were compared with hypocalcemia using logistic regression. Receiver operating characteristic analysis of IPTH measures as predictors of hypocalcemia was performed, and the area under the curve (AUC) was calculated. Overall, 119 patients were included. Forty-seven percent of the patients developed postoperative hypocalcemia, including 26 (22%) with mild and 30 (25%) with severe hypocalcemia. Thirteen patients had hypocalcemic symptoms. Median IPTH gradient and postoperative IPTH each differed significantly by category of hypocalcemia (P gradient was significantly associated with odds of severe and symptomatic hypocalcemia (adjusted odds ratio [aOR]: 1.21, 95% confidence interval [CI]: 1.06-1.39 and aOR: 1.34, 95% CI: 1.05-1.71 per 10% increase), whereas lower postoperative IPTH was not (aOR: 1.27, 95% CI: 0.95-1.68 and aOR: 1.44, 95% CI: 0.90-2.31 per 10 pg/mL decrease). The AUC for predicting severe hypocalcemia was nonsignificantly higher for IPTH gradient than postoperative IPTH (AUC = 0.77 vs. 0.69, P = .10). The AUC for predicting symptomatic hypocalcemia was significantly higher for IPTH gradient (AUC = 0.75 vs. 0.72, P = .03). Our results suggest that the IPTH gradient may be more useful than postoperative IPTH alone in predicting risk of post-thyroidectomy hypocalcemia. 4.

    Post-operative trochanteric bursitis is a known complication secondary to the surgical approach in total hip arthroplasty. This phenomenon may be partially attributable to repetitive microtrauma generated when soft tissues rub against implanted hardware. Significant rates of post-operative trochanteric bursitis have been observed following procedures in which a trochanteric fixation device, such as a bolt-washer mechanism or a cable-grip/claw system, is used to secure the trochanteric fragment after trochanteric osteotomy. We present a simple technique for use with a bolt-washer system or grip plate in which trochanteric components are covered in bone wax followed by a layer of cement to decrease friction and to diminish the risk of post-operative bursitis.

    BACKGROUND: A key element in enhanced postoperative recovery is early mobilization which, however, may be hindered by orthostatic intolerance, that is, an inability to sit or stand because of symptoms of cerebral hypoperfusion as intolerable dizziness, nausea and vomiting, feeling of heat...... of orthostatic intolerance. In contrast, 8 (50%) and 2 (12%) patients were orthostatic intolerant at 6 and approximately 22 h after surgery, respectively. Before surgery, SAP, DAP, and TPR increased (P0.05) and Scv(O2) decreased (P... the preoperative evaluation (P>0.05). CONCLUSIONS: The early postoperative postural cardiovascular response is impaired after radical prostatectomy with a risk of orthostatic intolerance, limiting early postoperative mobilization. The pathogenic mechanisms include both impaired TPR and CO responses....

    Bariatric surgery, especially in the morbidly obese, can be associated with serious postoperative problems. Apart from surgical complications requiring reoperation, pre-existing disease can worsen during the postoperative period. Bariatric patients require particular therapeutic approaches such as adapted fluid and pain management, management of obstructive sleep apnoea-hypopnea, early ambulation and measures for preventing pressure ulcers. Another challenging issue is the early identification and management of postoperative intraabdominal sepsis (IAS) before the onset of organ dysfunction. Early and frequent ambulation is thought to reduce risk of pressure ulcers, deep vein thrombosis, resedation, pain, pneumonia and atelectasis. To prevent spine injury of health care workers it is necessary to provide appropriate support with special beds, lifting and transfer devices.

    Recently, skeletal muscle depletion (sarcopenia) has been reported to influence postoperative outcomes after certain procedures. This study investigated the impact of sarcopenia on postoperative outcomes following pancreaticoduodenectomy (PD). We performed a retrospective study of consecutive patients (n = 219) who underwent PD at our institution between January 2007 and May 2013. Sarcopenia was evaluated using preoperative computed tomography. We evaluated postoperative outcomes and the influence of sarcopenia on short-term outcomes, especially infectious complications. Subsequently, multivariate analysis was used to assess the impact of prognostic factors (including sarcopenia) on postoperative infections. The mortality, major complication, and infectious complication rates for all patients were 1.4%, 16.4%, and 47.0%, respectively. Fifty-five patients met the criteria for sarcopenia. Sarcopenia was significantly associated with a higher incidence of in-hospital mortality (P = 0.004) and infectious complications (P sarcopenia (odds ratio = 3.43; P Sarcopenia is an independent preoperative predictor of infectious complications after PD. Clinical assessment combined with sarcopenia may be helpful for understanding the risk of postoperative outcomes and determining perioperative management strategies.

    We retrospectively analyzed the treatment outcomes of post-operative radiation therapy (PORT) after radical surgery for locally advanced hypopharyngeal carcinoma. From August 2000 to July 2009, 62 patients with hypopharyngeal squamous cell carcinoma were treated with radical surgery followed by PORT in our institute. All patients were followed up for more than 6 months or until any events. All patients underwent a total laryngectomy and neck node dissection prior to PORT. There were 55 male and 7 female patients, with ages ranging from 45 to 82 years (median: 64). Pathologic stage was IVA in 55 and IVB in 7 patients. Irradiation dose ranged from 46 to 70 Gy (median: 60). Twenty-four patients received concurrent chemotherapy. The median follow-up period for surviving patients was 43 months. The 3-year overall and relapse-free survival rates were 56% and 51%, respectively. There was 1 patient with local recurrence and 9 patients with neck node recurrence, and the 3-year loco-regional control rate was 85%. There were 16 patients with distant metastases and the 3-year freedom form distant metastasis rate was 71%. Patients with extra nodal invasion (ENI) had a statistically poorer prognosis (p=0.008). The incidence rate of loco-regional recurrence and distant metastasis were statistically higher in the patients with ENI (p=0.017 and p=0.009, respectively). PORT with concurrent chemotherapy is deemed to be a standard treatment for such high-risk patients. Conformal and precise radiation treatment such as IMRT might also be considered for such high-risk patients in the near future. (author)

  1. Postoperative hypoxia and length of intensive care unit stay after cardiac surgery: the underweight paradox?

    Marco Ranucci

    Full Text Available Cardiac operations with cardiopulmonary bypass can be associated with postoperative lung dysfunction. The present study investigates the incidence of postoperative hypoxia after cardiac surgery, its relationship with the length of intensive care unit stay, and the role of body mass index in determining postoperative hypoxia and intensive care unit length of stay.Single-center, retrospective study.University Hospital. Patients. Adult patients (N = 5,023 who underwent cardiac surgery with CPB.None.According to the body mass index, patients were attributed to six classes, and obesity was defined as a body mass index >30. POH was defined as a PaO2/FiO2 ratio <200 at the arrival in the intensive care unit. Postoperative hypoxia was detected in 1,536 patients (30.6%. Obesity was an independent risk factor for postoperative hypoxia (odds ratio 2.4, 95% confidence interval 2.05-2.78, P = 0.001 and postoperative hypoxia was a determinant of intensive care unit length of stay. There is a significant inverse correlation between body mass index and PaO2/FiO2 ratio, with the risk of postoperative hypoxia increasing by 1.7 folds per each incremental body mass index class. The relationship between body mass index and intensive care unit length of stay is U-shaped, with longer intensive care unit stay in underweight patients and moderate-morbid obese patients.Obese patients are at higher risk for postoperative hypoxia, but this leads to a prolonged intensive care unit stay only for moderate-morbid obese patients. Obese patients are partially protected against the deleterious effects of hemodilution and transfusions. Underweight patients present the "paradox" of a better lung gas exchange but a longer intensive care unit stay. This is probably due to a higher severity of their cardiac disease.

    Frozen shoulder is a potential complication after shoulder surgery. It is a clinical condition that is often associated with marked disability and can have a profound effect on the patient's quality of life. The incidence, etiology, pathology and prognostic factors of postoperative frozen shoulder after shoulder surgery are not known. The purpose of this explorative study was to determine the incidence of postoperative frozen shoulder after various operative shoulder procedures. A second aim was to identify prognostic factors for postoperative frozen shoulder after shoulder surgery. 505 consecutive patients undergoing elective shoulder surgery were included in this prospective cohort study. Follow-up was 6 months after surgery. A prediction model was developed to identify prognostic factors for postoperative frozen shoulder after shoulder surgery using the TRIPOD guidelines. We nominated five potential predictors: gender, diabetes mellitus, type of physiotherapy, arthroscopic surgery and DASH score. Frozen shoulder was identified in 11% of the patients after shoulder surgery and was more common in females (15%) than in males (8%). Frozen shoulder was encountered after all types of operative procedures. A prediction model based on four variables (diabetes mellitus, specialized shoulder physiotherapy, arthroscopic surgery and DASH score) discriminated reasonably well with an AUC of 0.712. Postoperative frozen shoulder is a serious complication after shoulder surgery, with an incidence of 11%. Four prognostic factors were identified for postoperative frozen shoulder: diabetes mellitus, arthroscopic surgery, specialized shoulder physiotherapy and DASH score. The combination of these four variables provided a prediction rule for postoperative frozen shoulder with reasonable fit. Level II, prospective cohort study.

    Full Text Available To identify the risk factors associated with postoperative vomiting (POV in paediatric population undergoing common surgeries. The risk factors studied for association with POV were age> 5 years, female gender, previous history of POV/motion sickness, type of surgery and duration of anaesthesia> 45 min. A total of 100 ASA grade I and II patients of either sex aged between 2-12 years undergoing elective surgical procedures were screened for the study. All patients underwent similar anaesthe-sia protocol and received two antiemetic agents (ondansetron 0.05mg.kg-1 and dexamethasone 0.15mg.kg-1 in premedication. The patients were observed for 24 hours postoperatively for the incidence of vomiting, number of times rescue antiemetic given and any adverse reaction to antiemetic.Overall 34% patients (34/100 developed POV of which 26 had only one episode and 8 patients had 2 episodes during first 24 h. Incidence of POV was 13% (13/100 in first 4 h whereas it was 29% (29/100 in late postoperative period. In early post operative period, POV was not associated significantly with any predicted risk factors. However, age>5years, duration of anaesthesia>45 minutes and history of motion sickness/POV were significantly associated in late postoperative period(4-24h. Female gender and type of surgery were not associated with increased POV. The combination antiemetic effectively prevented POV in early postoperative period (0-4h only but not in late postoperative period(0-24h.

    To determine whether poor nutritional status can predict postoperative delirium in elderly adults undergoing hip fracture surgery. Prospective observational cohort study. Italian orthogeriatric unit. Individuals aged 70 and older (mean age 84.0 ± 6.6, 74.5% female) consecutively admitted for surgical repair of a proximal femur fracture between September 2012 and April 2016 (N = 415). Participants underwent a comprehensive geriatric assessment including nutritional status, which was evaluated using the Mini Nutritional Assessment Short Form (MNA-SF). The MNA-SF-based three-class stratification was tested using multivariable logistic regression to assess its role in predicting postoperative delirium (outcome). Seventy-eight malnourished individuals (MNA-SF score 0-7), 185 at risk of malnutrition (MNA-SF score 8-11), and 152 who were well nourished (MNA-SF score 12-14) were compared. On average, individuals with poor nutritional status were more disabled and more cognitively impaired than those who were well nourished and those at risk of malnutrition. Moreover, those who were malnourished were more likely to have postoperative delirium. Multivariate regression analysis adjusted for age, sex, comorbidity, functional impairment, preoperative cognitive status, and American Society of Anesthesiologists score showed that those who were at risk of malnutrition (odds ratio (OR) = 2.42, 95% confidence interval (CI) = 1.29-4.53) and those who were overtly malnourished (OR = 2.98, 95% CI = 1.43-6.19) were more likely to develop postoperative delirium. This is the first study in a Western population showing that risk of malnutrition and overt malnutrition, as assessed using the MNA-SF, are independent predictors of postoperative delirium. Accordingly, nutritional status should be assessed in individuals with hip fracture before surgery to determine risk of developing delirium. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Infantile cataract surgery bears a significant risk for postoperative glaucoma, and no consensus exists on factors that may reduce this risk. To assess the effect of primary intraocular lens implantation and timing of surgery on the incidence of postoperative glaucoma. We searched multiple databases to July 14, 2013, to identify studies with eligible patients, including PubMed, MEDLINE, EMBASE, ISI Web of Science, Scopus, Central, Google Scholar, Intute, and Tripdata. We also searched abstracts of ophthalmology society meetings. We included studies reporting on postoperative glaucoma in infants undergoing cataract surgery with regular follow-up for at least 1 year. Infants with concurrent ocular anomalies were excluded. Authors of eligible studies were invited to contribute individual patient data on infants who met the inclusion criteria. We also performed an aggregate data meta-analysis of published studies that did not contribute to the individual patient data. Data were pooled using a random-effects model. Time to glaucoma with the effect of primary implantation, additional postoperative intraocular procedures, and age at surgery. Seven centers contributed individual patient data on 470 infants with a median age at surgery of 3.0 months and median follow-up of 6.0 years. Eighty patients (17.0%) developed glaucoma at a median follow-up of 4.3 years. Only 2 of these patients had a pseudophakic eye. The risk for postoperative glaucoma appeared to be lower after primary implantation (hazard ratio [HR], 0.10 [95% CI, 0.01-0.70]; P = .02; I(2) = 34%), higher after surgery at 4 weeks or younger (HR, 2.10 [95% CI, 1.14-3.84]; P = .02; I(2) = 0%), and higher after additional procedures (HR, 2.52 [95% CI, 1.11-5.72]; P = .03; I(2) = 32%). In multivariable analysis, additional procedures independently increased the risk for glaucoma (HR, 2.25 [95% CI, 1.20-4.21]; P = .01), and primary implantation independently reduced it (HR, 0.10 [95% CI, 0.01-0.76]; P =

    Performance characteristics of the central nervous, cardiovascular, respiratory and muscular systems in man postoperatively have received little investigative attention, despite the well known syndrome of postoperative fatigue. The impairmen in perception and psychomotor skills that has been shown to result from caloric restriction, bedrest, sedation and sleep deprivation suggests that a similar deficit may occur after surgical procedures. After a simple elective surgical procedure, maximal oxygen uptake decreases and the adaptability of heart rate to submaximal workloads is impaired. Similar deleterious effects on cardiorespiratory performance have been documented with starvation and bedrest; an understanding of cardiorespiratory performance postoperatively awaits further investigation. Maximal muscular force of contraction is also impaired by caloric restriction and bedrest, suggesting that similar effects may be seen in the postoperative state, although this has not been studied. A better understanding of the syndrome of postoperative fatigue could be achieved by a descriptive analysis of physiologic performance postoperatively. Such descriptive data could form the basis for objective evaluation of therapeutic measures intended to improve performance, such as nutritional supplementation and pharmacologic intervention. The observation that exercise with the patient in the supine position may decrease the impairment in maximal aerobic power otherwise expected in immobilized patients suggests that controlled exercise therapy may be of value in reducing physiologic impairment postoperatively.

    Full Text Available Treatment of the elderly is becoming increasingly common problem and is of interest, because in the future this phenomenon will affect most of us. For many years, he observed in different countries increasingly rapid aging of the population, including in Poland. The operation in such a patient poses a high risk of complications and life-threatening conditions. Their age makes in the postoperative period there are many medical problems. Many factors can affect the scope of a different self-care nursing with such a patient.

    Full Text Available Objective: The purpose of this study was to evaluate the postoperative complications for patients with adenocarcinoma of esophagogastric junction. Methods: Two hundred and eighty subjects with adenocarcinoma of esophagogastric junction who received operation were retrospectively analyzed from June 2006 to December 2010 in the Department of Oncology of First Affiliated Hospital of Bengbu Medical College, Bengbu, China. The postoperative complication such as ventricular premature beat, atrial fibrillation, supraventricular tachycardia, heart failure, pulmonary infection, pulmonary atelectasis, respiratory failure, bronchospasm, anastomotic leakage, gastroplegia, pleural infection, and cerebral accident were reviewed and recorded by to doctors. Moreover, the correlation between clinical characteristics and postoperative complication was analyzed by statistical methods. Results: A total of 70 complications were found for the included 280 cases of adenocarcinoma of esophagogastric junction with general incidence of 25%. For the relationship between clinical characteristics and postoperative complication analysis, no significant association of gender, age, operation time, operative approach, tumor differentiation, and clinical states was found with the postoperative complications (P > 0.05; but the complication rate in patients with basic disease of heart and lung was significant than the patients without this kind of disease (P < 0.05. Conclusion: The positive operative complications for patients with adenocarcinoma of esophagogastric junction were relative high. Moreover, basic heart and lung diseases can increase the risk of developing positive operative complications.

    Lin, Sharon; Melki, Sami; Lisgaris, Michelle V; Ahadizadeh, Emily N; Zender, Chad A

    Surgical site infection (SSI) with methicillin-resistant Staphylococcus aureus (MRSA) is a serious post-operative complication, with head and neck cancer patients at greater risk due to the nature of their disease. Infection with MRSA has been shown to be costly and impart worse outcomes on patients who are affected. This study investigates incidence and risks for MRSA SSIs at a tertiary medical institution. This study reviewed 577 head and neck procedures from 2008 to 2013. Twenty-one variables (i.e. tumor characteristics, patient demographics, operative course, cultures) were analyzed with SPSS to identify trends. A multivariate analysis controlled for confounders (age, BMI, ASA class, length of stay) was completed. We identified 113 SSIs of 577 procedures, 24 (21.23%) of which were MRSA. Of all analyzed variables, hospital exposure within the preceding year was a significant risk factor for MRSA SSI development (OR 2.665, 95% CI: 1.06-6.69, z statistic 2.086, p=0.0369). Immunosuppressed patients were more prone to MRSA infections (OR 14.1250, 95%CI: 3.8133-52.3217, p<0.001), and patients with a history of chemotherapy (OR 3.0268, 95% CI: 1.1750-7.7968, p=0.0218). Furthermore, MRSA SSI resulted in extended post-operative hospital stays (20.8±4.72days, p=0.031). Patients who have a history of chemotherapy, immunosuppression, or recent hospital exposure prior to their surgery are at higher risk of developing MRSA-specific SSI and may benefit from prophylactic antibiotic therapy with appropriate coverage. Additionally, patients who develop MRSA SSIs are likely to have an extended postoperative inpatient stay. Copyright © 2017 Elsevier Inc. All rights reserved.

    2010-03-01

    In the last several years, there have been numerous advancements in the field of pulmonary hypertension as a whole, but there have been few changes in the management of children with pulmonary hypertension after cardiac surgery. Patients at particular risk for postoperative pulmonary hypertension can be identified preoperatively based on their cardiac disease and can be grouped into four broad categories based on the mechanisms responsible for pulmonary hypertension: 1) increased pulmonary vascular resistance; 2) increased pulmonary blood flow with normal pulmonary vascular resistance; 3) a combination of increased pulmonary vascular resistance and increased blood flow; and 4) increased pulmonary venous pressure. In this review of the immediate postoperative management of pulmonary hypertension, various strategies are discussed including medical therapies, monitoring, ventilatory strategies, and weaning from these supports. With early recognition of patients at particular risk for severe pulmonary hypertension, management strategies can be directed at preventing or minimizing hemodynamic instability and thereby prevent the development of ventricular dysfunction and a low output state.

    To investigate the role of psychiatric dimensions, behavioral or substance addictions and demographical variables as determinants of pathological gambling among nursing students. Multicenter cross-sectional study. From June to October 2015 a survey was carried out among Italian Nursing students. Data were collected using a six-section tool. Nursing students who completed the survey numbered 1083, 902 (83.3%) had some problems with gambling and 29 (2.7%) showed pathological gambling. Percentage of pathological gambling was significantly associate with illicit drug/alcohol use (65.5%; p=0.001) and with male gender (58.6%) comparing to student nurse with non-pathological gambling (20%) and those with some problem (24.2%). Significant main effect was observed for IAT score (Beta=0.119, t=3.28, p=0.001): higher IAT scores were associated with higher SOGS scores. Italian nursing students have some problems with gambling and pathological gambling problem, and males are those who have more problems. Results might be useful for faculties of health professionals to identify students at risk in an early stage, to direct prevention tailored interventions. Nursing faculties should be aware of the prevalence of Gambling among students. Prevention interventions should be planned to minimize the risk of gambling behavior in the future nurses' health care workers. Copyright © 2017 Elsevier Inc. All rights reserved.

    Postoperative nausea and vomiting belong to fairly frequent postoperative complications, but they occupy a distant position on the list of complications, which most probably result from a general conviction that they do not pose a direct threat to patients. The objective of this work is specification of factors facilitating occurrence of postoperative nausea and vomiting, and determination of frequency of their occurrence in patients operated under general anesthesia. Questionnaire about the occurrence of postoperative nausea and vomiting (PONV), was carried out and included 253 adult sick persons (102 female and 151 male patients), in the age between 23-76 (average 42.3 +/- 6.1 years), who had undergone operative procedure in the field of abdominal and urology surgery, orthopedic, thyroid surgery and laryngological, ophthalmology and plastic surgery, under general anesthesia. The questionnaire form included preoperative characteristics of a patient (age, sex, smoking, motion sickness and migraine headaches in history, and PONV occurring earlier), type of operative procedure, used anesthetic agents, and analgesic agents applied in postoperative analgesia. The anesthesiologist administering anesthetic was not informed about the investigation carried out and did not receive any additional pieces of advice regarding the type of applied anesthetic agents or the method of conducting postoperative analgesia. Visual Analogue Scale (VAS) was used in the evaluation of nausea. Nausea and vomiting were assessed every two hours within the first postoperative 12 hours and every 4 hours for the next 24 hours. Nausea and vomiting were treated as two separate complications. Nausea itself occurred in 22.7% of patients; whereas vomiting in 13.2%. Both symptoms occurred in 14.2% of patients. Nausea occurred 4.1 +/- 0.8 hours after operation; whereas vomiting after 5.3 +/- 1.1 hours. Women suffered more often than men from (R = 0.678 p patients suffering from PONV earlier (R = 0

    To identify the incidence and associated factors of the postoperative hydronephrosis in pediatric patients who underwent ureterorenoscopy (URS) for renal or ureteral stones. We evaluated the results of 116 patients who underwent semirigid or flexible URS retrospectively. Primary end points of the study were to determine the incidence of postoperative hydronephrosis and factors associated with the development of postoperative hydronephrosis. Logistic regression analysis was used to define factors associated with the presence of hydronephrosis. Mean age of the population was 9.5 years and mean stone size was 9.4 mm. Hydronephrosis was detected in 32 (27.6%) patients. Stone-free status was achieved in 101 (87%) patients. Univariate analysis revealed history of ipsilateral URS, duration of operation, presence of impacted stone, development of ureteral injury during operation, and presentation with a renal colic episode as the parameter associated with increased risk of hydronephrosis. History of ipsilateral URS (odds ratio: 1.664, P = .027), presence of impacted stones (odds ratio: 1.788, P = .014), and development of ureteral injury during operation (odds ratio: 1.106, P = .039) were found to be the independent markers of developing postoperative hydronephrosis in a multivariate analysis. Ipsilateral hydronephrosis following URS develops in a significant portion of patients. In patients with history of ipsilateral procedure and those with an impacted stone and had ureteral injury, the risk of postoperative hydronephrosis is higher; therefore, physicians should keep these parameters in mind in the decision-making process of selective imaging postoperatively.

    The aim of this study was to determine the incidence of postoperative delirium (POD) and the presence of previous conditions related to its development. Prospective observational study. The study was performed in adult patients (n=221) scheduled for elective surgery and admitted to the postanesthesia care unit (PACU). The presence of POD was assessed by the Nursing Delirium Screening Scale at discharge from the PACU and 24hours after surgery. Descriptive analyses were carried out, and statistical comparisons were performed with Mann-Whitney U, χ(2), or Fisher exact test. Logistic regression analysis was used for evaluation of independent determinants of POD. POD was found in 25 patients (11%). Patients who developed POD were older (median age, 69 vs 57years; P<.001); had a higher American Society of Anesthesiologists physical status score (≥3) (60% vs 19%, respectively, had American Society of Anesthesiologists physical status III/IV; P<.001); and showed higher incidences of ischemic heart disease (24% vs 6%; P=.001), chronic kidney disease (20% vs 5%; P=.005), hypertension (80% vs 45%; P=.001), chronic obstructive pulmonary disease (20% vs 6%; P=.009), and low functional reserve (LFR) (24% vs 2%; P<.001). Age (odds ratio, 1.06; 95% confidence interval, 1.02-1.10; P=.003) and LFR (odds ratio, 8.04; 95% confidence interval, 3.95-32.27; P=.003) were considered independent risk factors for POD. The incidence of POD in the study population (11%) is consistent with that described in the literature (5%-15%). The comorbidities associated with its development were ischemic heart disease, hypertension, chronic kidney disease, LFR, and chronic obstructive pulmonary disease. Age ≥65years and LFR were independent risk factors for POD development. Copyright © 2016 Elsevier Inc. All rights reserved.

    Poor nutrition status is considered a risk factor for postoperative complications in the adult population. In elderly patients, who often have a poor nutrition status, this relationship has not been substantiated. Thus, the aim of this systematic review was to assess the merit of preoperative nutrition parameters used to predict postoperative outcome in elderly patients undergoing general surgery. A systematic literature search of 10 consecutive years, 1998-2008, in PubMed, EMBASE, and Cochrane databases was performed. Search terms used were nutrition status, preoperative assessment, postoperative outcome, and surgery (hip or general), including their synonyms and MeSH terms. Limits used in the search were human studies, published in English, and age (65 years or older). Articles were screened using inclusion and exclusion criteria. All selected articles were checked on methodology and graded. Of 463 articles found, 15 were included. They showed profound heterogeneity in the parameters used for preoperative nutrition status and postoperative outcome. The only significant preoperative predictors of postoperative outcome in elderly general surgery patients were serum albumin and ≥ 10% weight loss in the previous 6 months. This systematic review revealed only 2 preoperative parameters to predict postoperative outcome in elderly general surgery patients: weight loss and serum albumin. Both are open to discussion in their use as a preoperative nutrition parameter. Nonetheless, serum albumin seems a reliable preoperative parameter to identify a patient at risk for nutrition deterioration and related complicated postoperative course.

  18. Difference between early versus delayed postoperative physical rehabilitation protocol following arthroscopic rotator cuff repair

    2016-01-01

    Conclusion Significant improvement in pain, ROM, and function after arthroscopic rotator cuff repair was seen at 1 year postoperatively, regardless of early or delayed postoperative rehabilitation protocols. However, early motion increases pain scores and may increase the possibility of rotator cuff retear but with early regain of ROM. A delayed rehabilitation protocol with immobilization for 6 weeks would be better for tendon healing without risk for retear or joint stiffness and easily convalescence with less postoperative pain.

    Purpose: To review the National Cancer Database (NCDB) to evaluate postoperative high-risk cervical cancer patients for factors associated with a benefit from chemoradiation therapy (CRT) over external beam radiation therapy alone (EBRT). Methods and Materials: The National Cancer Database was queried for women with cervical cancer treated with hysterectomy and adjuvant EBRT from 2002 to 2012. Only patients with pathologic lymph node involvement (LN+), positive surgical margins, and/or parametrial invasion were included in our analysis (on the basis of Peter's criteria). Univariable and multivariable analyses (MVA) were performed, and hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated to investigate for factors associated with of CRT utilization and overall survival (OS). Results: A total of 3053 patients met inclusion criteria, and 2479 received adjuvant CRT (81%), whereas 574 (19%) received EBRT alone. Factors associated with increased CRT utilization on MVA included age <69 years, year of diagnosis ≥2008, non-adenocarcinoma histology, and LN+. Use of CRT improved OS among the entire cohort on MVA (HR 0.76, CI 0.601-0.962; P=.022). On MVA, CRT improved OS in patients with LN+ as their sole Peter's criteria (HR 0.58, CI 0.413-0.814; P=.002). Chemoradiation therapy did not improve OS in patients with only positive margins (P=.73), only parametrial invasion (P=.95), or any combination of these 2 factors without LN+ (P=.63). Conclusions: The use of adjuvant CRT after hysterectomy improves OS in patients with high-risk cervical cancer compared with EBRT alone, but this benefit seems to be restricted to patients with LN+. The benefits of adjuvant CRT over EBRT alone in patients with parametrial invasion and/or positive margins (without nodal involvement) are unknown.

  20. Postoperative Paraplegia as a Result of Undiagnosed Primitive Neuroectodermal Tumor, Not Epidural Analgesia

    Directory of Open Access Journals (Sweden)

    Pei-Ching Hung

    2007-10-01

    Full Text Available Postoperative paraplegia is a rare complication after epidural analgesia and often occurs with spinal hematoma or cord injury. We present the case of a 16-year-old girl who suffered from a tumor mass in the neck and abdomen who underwent gynecologic operation. Preoperatively, liver metastasis was found by computed tomography. Pathologic findings revealed that the abdominal mass was an ovarian dermoid cyst. After the operation, the patient complained of paraplegia while receiving epidural analgesia for postoperative pain control. A peripheral primitive neuroectodermal tumor in the thoracic and lumbar spines with spinal cord compression was later detected using magnetic resonance imaging. Learning from this case, we suggest that when a patient is preoperatively diagnosed with tumor metastasis, back pain and soreness, spinal cord compression from tumor metastasis should be excluded before epidural analgesia is implemented.

    Retrospective multi-institutional case series. The anterior cervical discectomy and fusion (ACDF) affords the surgeon the flexibility to treat a variety of cervical pathologies, with the majority being for degenerative and traumatic indications. Limited data in the literature describe the presentation and true incidence of postoperative surgical site infections. A retrospective multicenter case series study was conducted involving 21 high-volume surgical centers from the AOSpine North America Clinical Research Network, selected for their excellence in spine care and clinical research infrastructure and experience. Medical records for 17 625 patients who received cervical spine surgery (levels from C2 to C7) between January 1, 2005, and December 31, 2011, inclusive, were reviewed to identify the occurrence of 21 predefined treatment complications. Patients who underwent an ACDF were identified in the database and reviewed for the occurrence of postoperative anterior cervical infections. A total of 8887 patients were identified from a retrospective database analysis of 21 centers providing data for postoperative anterior cervical infections (17/21, 81% response rate). A total of 6 postoperative infections after ACDF were identified for a mean rate of 0.07% (range 0% to 0.39%). The mean age of patients identified was 57.5 (SD = 11.6, 66.7% female). The mean body mass index was 22.02. Of the total infections, half were smokers (n = 3). Two patients presented with myelopathy, and 3 patients presented with radiculopathic-type complaints. The mean length of stay was 4.7 days. All patients were treated aggressively with surgery for management of this complication, with improvement in all patients. There were no mortalities. The incidence of postoperative infection in ACDF is exceedingly low. The management has historically been urgent irrigation and debridement of the surgical site. However, due to the rarity of this occurrence, guidance for management is limited to

    1997-01-01

    Purpose/Objective: This study reports on a unique experience in the management of patients with advanced head and neck squamous cell carcinomas (HNSCC) in which, between 1982 and 1990, patients with varied risk for recurrence were either referred for immediate postoperative irradiation by one surgical group or offered radiotherapy after surgical failure by the other. We have previously demonstrated in patients with high risk for recurrence that combined surgery and postoperative radiotherapy (S/RT) resulted in improved loco-regional tumor control (LRC) and overall patient survival (OS) for the entire patient cohort. This updated and expanded analysis describes the benefit of postoperative irradiation for patients with HNSCC depending upon relative risk factors for recurrence and different subsites of primary tumors. Materials and Methods: Of 219 patients, 190 were evaluable because of tumor locations in the major subsites analyzed, i.e. oral cavity (OC), oropharynx (OP), hypopharynx (HP), and larynx (L). Depending upon the philosophy of the two surgical groups, 79 patients were treated with combined S/RT and 111 with S alone with a >90% compliance. Minimum 2-year follow-up applies to all data reported. The two patient groups were well balanced with respect to tumor stages (AJCC 1983) and other patient characteristics. Histopathological review revealed 88 cases with one risk factor for recurrence, 49 patients with positive resection margin (PRM) and 39 with extracapsular extension (ECE); an additional 22 patients presented with both risk factors and 80 patients were found to have no risk factors. S, consisting of wide local excisions or radical resections including neck dissections, and postoperative RT with doses between 50 and 70 Gy were similar for both groups. Statistical evaluations consisted of Kaplan-Meier analyses to calculate LRC and OS rates and of multivariate Cox's proportional hazard models to estimate significance of treatment effects including S vs. S

    The purpose of this case-control study was to evaluate the impact of hybrid minimally invasive esophagectomy for cancer on surgical stress response and nutritional status. All 34 consecutive patients undergoing hybrid minimally invasive esophagectomy for cancer at our surgical unit between 2008 and 2013 were retrospectively compared with 34 patients undergoing esophagectomy with open gastric tubulization (open), matched for neoadjuvant therapy, pathological stage, gender and age. Demographic data, tumor features and postoperative course (including quality of life and systemic inflammatory and nutritional status) were compared. Postoperative course was similar in terms of complication rate. Length of stay in intensive care unit was shorter in patients undergoing hybrid minimally invasive esophagectomy (P = 0.002). In the first postoperative day, patients undergoing hybrid minimally invasive esophagectomy had lower C-reactive protein levels (P = 0.001) and white cell blood count (P = 0.05), and higher albumin serum level (P = 0.001). In this group, albumin remained higher also at third (P = 0.06) and seventh (P = 0.008) postoperative day, and C-reactive protein resulted lower at third post day (P = 0.04). Hybrid minimally invasive esophagectomy significantly improved the systemic inflammatory and catabolic response to surgical trauma, contributing to a shorter length of stay in intensive care unit. © 2015 International Society for Diseases of the Esophagus.

    Purpose To develop a machine learning model that allows high-risk breast lesions (HRLs) diagnosed with image-guided needle biopsy that require surgical excision to be distinguished from HRLs that are at low risk for upgrade to cancer at surgery and thus could be surveilled. Materials and Methods Consecutive patients with biopsy-proven HRLs who underwent surgery or at least 2 years of imaging follow-up from June 2006 to April 2015 were identified. A random forest machine learning model was developed to identify HRLs at low risk for upgrade to cancer. Traditional features such as age and HRL histologic results were used in the model, as were text features from the biopsy pathologic report. Results One thousand six HRLs were identified, with a cancer upgrade rate of 11.4% (115 of 1006). A machine learning random forest model was developed with 671 HRLs and tested with an independent set of 335 HRLs. Among the most important traditional features were age and HRL histologic results (eg, atypical ductal hyperplasia). An important text feature from the pathologic reports was "severely atypical." Instead of surgical excision of all HRLs, if those categorized with the model to be at low risk for upgrade were surveilled and the remainder were excised, then 97.4% (37 of 38) of malignancies would have been diagnosed at surgery, and 30.6% (91 of 297) of surgeries of benign lesions could have been avoided. Conclusion This study provides proof of concept that a machine learning model can be applied to predict the risk of upgrade of HRLs to cancer. Use of this model could decrease unnecessary surgery by nearly one-third and could help guide clinical decision making with regard to surveillance versus surgical excision of HRLs. © RSNA, 2017.

    Active surveillance is now the treatment of choice in men with low risk prostate cancer. Although there is no consensus on which patients are eligible for active surveillance, prostate specific antigen above 10 ng/ml is generally excluded. In an attempt to determine the validity of using a prostate specific antigen cutoff of 10 ng/ml to counsel men considering active surveillance we analyzed a multi-institution database to determine the pathological outcome in men with prostate specific antigen greater than 10 ng/ml but histologically favorable risk prostate cancer. We queried a prospectively maintained database of men with histologically favorable risk prostate cancer who underwent radical prostatectomy between 2003 and 2015. The cohort was categorized into 3 groups based on prostate specific antigen level, including low-less than 10 ng/ml, intermediate-10 or greater to less than 20 and high-20 or greater. Associations of prostate specific antigen group with adverse pathological and oncologic outcomes were analyzed. Of 2,125 patients 1,327 were categorized with histologically favorable risk disease. However on multivariate analyses the rates of up staging and upgrading were similar between the intermediate and low prostate specific antigen groups. In contrast compared to the intermediate prostate specific antigen group the high group had higher incidences of up staging (p = 0.02) and upgrading to 4 + 3 or greater disease (p = 0.046). Biochemical recurrence-free survival rates revealed no pairwise intergroup differences except between the low and high groups. Patients with preoperatively elevated prostate specific antigen between 10 and less than 20 ng/ml who otherwise had histologically favorable risk prostate cancer were not at higher risk for adverse pathological outcomes than men with prostate specific antigen less than 10 ng/ml.

    Full Text Available BACKGROUND Abdominal hysterectomy is one of the most frequently performed surgical procedures in women. The non-ambulatory postoperative period is a high risk period for the development of various complications like wound infection, venous stasis, lower respiratory infection, secondary haemorrhage, deep vein thrombosis, pulmonary embolism, paralytic ileus etc. Prolonged surgery, delayed ambulation and not feeding the patient within 48 hours of surgery are often associated with post-operative morbidity and mortality. This study aims to assess the effectiveness of Scheduled Ambulation on early post-operative outcome among patients undergone abdominal hysterectomy by introduction of Scheduled Ambulation from second day of surgery. MATERIALS AND METHODS Method used is quantitative and quasi experimental post-test control method. Scheduled ambulation technique and pattern were taught pre operatively to 35 patients consecutively selected from general and post-operative ward who formed the experimental group. They were given scheduled ambulation from second to fifth post-operative days and results analysed. Another 35 patients taken as control were given the routine post-operative care. Data Analysis- was performed using SPSS version 17.0. Between group comparisons, quantitative variables analysed by Chisquare test p value >0, 05 considered significant. RESULTS The indication of hysterectomy was fibroid uterus in 80% of the control group and 88, 6% of the experimental group. 51.4% of the hysterectomies were encountered in the age group 40-49 years. There was a statistically significant reduction in the severity of pain, fatigue, postural hypotension and risk for developing Deep vein thrombosis in the experimental group on practicing Scheduled Ambulation from second to fifth post-operative days. CONCLUSION Scheduled ambulation helped the abdominal hysterectomy patients to recover from fatigue, pain, postural hypotension and risk for Deep vein thrombosis

    The purpose of this study was to describe the incidence, clinical characteristics, and outcome of eccentric macular holes presenting after vitrectomy and internal limiting membrane (ILM) peeling for the treatment of macular pathology and discuss the pathogenesis of holes formation. A retrospective, noncomparative, interventional case-series study of five patients who developed eccentric macular holes postoperatively following vitrectomy in 198 consecutive patients who underwent ILM peeling for idiopathic macular hole and epiretinal membrane formation between 2008 and 2015. Five patients (2.5 %) developed full-thickness eccentric macular holes postoperatively. Three patients presented with a single eccentric macular hole, one patient had an eccentric hole after a failed idiopathic macular hole surgery and one patient developed four eccentric macular holes. The mean diameter of the holes was 584 μm (range 206-1317 μm) and the average time of holes formation after vitrectomy was 27.7 weeks (range 1-140 weeks). Postoperative best-corrected visual acuity ranged from "counting fingers" to 20/25. The eyes with the holes distant from the fovea had the best final visual acuity. No further intervention was attempted and no complications occurred. The mean follow-up time was 26.8 months. The postoperative macular holes after vitrectomy and ILM peeling were variable in number, size, and time of appearance but remained stable and were not associated with any complications. The pathogenesis of macular holes is most consistent with contraction of the residual ILM or secondary epimacular proliferation probably stimulated by ILM peeling.

    In a randomised trial, radical prostatectomy (RP) followed by adjuvant radiotherapy (aRT) was compared with RP alone in patients with pT3 pN0 prostate cancer with or without positive margin at local pathology (German Cancer Society trial numbers ARO 96-02/AUO AP 09/95). A pathology review was performed on 85% of RP specimens of patients to investigate the influence of pathology review on the analysis. Patients post-RP (n=385) were randomised before achieving an undetectable prostate-specific antigen (PSA) level to either wait and see (n=192) or 60Gy aRT (n=193). Of 307 patients with undetectable PSA after RP, 262 had pathology review. These results were included prospectively into the analysis. Agreement between local and review pathology was measured by the total percentage of agreement and by simple kappa statistics. The prognostic reliability for the different parameters was analysed by Cox regression model. Event-free rates were determined by Kaplan-Meier analysis with a median follow-up of 40 mo for the wait-and-see arm and 38.5 mo for the aRT arm. There was fair concordance between pathology review and local pathologists for seminal vesicle invasion (pT3c: 91%; κ=0.76), surgical margin status (84%; κ=0.65), and for extraprostatic extension (pT3a/b: 75%; κ=0.74). Agreement was much less for Gleason score (47%; κ=0.42), whereby the review pathology resulted in a shift to Gleason score 7. In contrast to the analysis of progression-free survival with local pathology, the multivariate analysis including review pathology revealed PSMs and Gleason score >6 as significant prognostic factors. Phase 3 studies of postoperative treatment of prostate cancer should be accomplished in the future with a pathology review. In daily practice, a second opinion by a pathologist experienced in urogenital pathology would be desirable, in particular, for high-risk patients after RP.

    Limited data are currently available regarding the outcomes of radical prostatectomy (RP) in men with low-risk prostate cancer who were initially managed by active surveillance (AS). To evaluate the pathologic outcomes of patients who underwent RP following initial AS. We analyzed the records of 67 patients who underwent RP following initial AS begun between 1993 and 2011. All patients underwent confirmatory biopsy to reassess eligibility for AS. RP was recommended for disease progression suggested by follow-up biopsies or imaging. Unfavorable disease was defined as having at least one of the following pathologic findings: Gleason score (GS) ≥4+3, extracapsular extension of tumor, seminal vesicle invasion, or lymph node involvement. A descriptive analysis was performed to assess pathologic features. Median time from confirmatory biopsy to RP was 1.7 yr (range: 0.3-7.8). Reasons for discontinuing AS to undergo RP included evidence of increased tumor volume or grade on follow-up biopsy, patient preference/anxiety, and findings on follow-up imaging in 46 patients (68.7%), 17 patients (25.3%), and 4 patients (6.0%), respectively. Pathologic analyses revealed organ-confined disease in 55 patients (82.1%), and GS was ≥4+3 in 9 (13.4%). Positive nodes were observed in three patients (4.4%) and positive surgical margin in two (3.0%). Overall, 19 patients (28.4%) had unfavorable disease. Of the biopsy criteria for triggering RP, Gleason patterns >3 were the most frequently associated with unfavorable disease (43.3%). One patient (1.5%) experienced biochemical recurrence during postoperative follow-up (median: 3.2 yr). Our study may be limited by its retrospective and single-institution nature. Most patients who started initially on AS after undergoing confirmatory biopsy showed pathologically organ-confined disease with a low GS at RP. Such findings provide further evidence that, overall, AS is a safe treatment approach. Copyright © 2013. Published by Elsevier B.V.

    2008-03-01

    Cardiovascular complications are associated with increased mortality and morbidity during the postoperative period, resulting in longer hospital stay and higher treatment costs. The aim of this study was to identify predictors of major postoperative cardiac complications. 187 patients undergoing noncardiac surgery, admitted to a surgical intensive care unit (ICU) between November 2004 and April 2005. Variables recorded were age, gender, American Society of Anesthesiologists (ASA) physical status, type and magnitude of surgery, mortality, ICU and hospital length of stay (LOS), Simplified Acute Physiology Score II (SAPS II), cardiac troponin I (cTnI) at postoperative day 0, 1, 2 and 3, history of hypertension, hyperlipidemia, Revised Cardiac Risk Index (RCRI) score, major cardiac events (MCE): acute myocardial infarction (AMI), pulmonary edema (PE), ventricular fibrillation (VF) or primary cardiac arrest (PCA). Correlations between variables and MCE were made by univariate analysis by simple logistic regression with odds ratio (OR) and 95% confidence interval (95% CI). Total of 14 MCE: 9 AMI, 1 VF, 4 PE. Significant risk factors for MCE were high-risk surgery (OR 8.26, 95% CI 1.76-38.85, p = 0.008), RCRI > or = 2 (OR 4.0, 95% CI 1.22-13.16, p = 0.022), admission cTnI (OR 1.46, 95% CI 1.07-1.99, p = 0.018); day 1 cTnI (OR 1.75, 95% CI 1.27-2.41, p = 0.001); day 2 cTnI (OR 2.23, 95% CI 1.24-3.98, p = 0.007), SAPS II (OR 1.08, 95% CI 1.04-1.12, p or = 2, cTnI levels and SAPS II were predictors of postoperative MCE. Patients with MCE had longer ICU stay and higher mortality rate.

    Since June 1988, we have treated 77 patients or 80 hips respectively with prophylactic irradiation. Individual risk factors included severe coxarthrosis grade IV, ipsi- or contralateral heterotopic ossification and severe hip trauma. As of July 1991 60 patients with a minimum follow-up of six months could be analyzed using clinical and radiological scoring systems. The patients had been prospectively randomized in two different treatment arms: 32 patients were treated with low dose (LD), five times 2 Gy daily fractions to a total dose of 10 Gy, whereas 28 patients were treated with high dose (HD), ten times 2 Gy (eight patients) or five times 3.5 Gy (20 patients). Operative procedures and individual risk factors were equally distributed in both groups. 23 patients (38% received indometacin three times 25 mg for six weeks, 19 patients (32%) diphosphonate EHDP 20 mg/kg body weight and 18 patients (30%) had no additional medication. 56/60 (93%) patients developed no significant heterotopic ossification and/or remained without impairment of their postoperative radiological and clinical hip status according to the applied Brooker and Harris Scores. Only 4/60 (7%) patients demonstrated treatment failures developing postoperative worsening one grade of Brooker score in two patients and two and three grades of Brooker score in the two others. Only 1/49 patients experienced a treatment failure, when radiotherapy had been initiated before and at postoperative day 4 compared to 3/11 patients initiated after postoperative day 4 (p [de

    We aimed to measure the prevalence and length of the problem of pathological video gaming or Internet use, to identify risk and protective factors, to determine whether pathological gaming is a primary or secondary problem, and to identify outcomes for individuals who become or stop being pathological gamers. A 2-year, longitudinal, panel study was performed with a general elementary and secondary school population in Singapore, including 3034 children in grades 3 (N = 743), 4 (N = 711), 7 (N = 916), and 8 (N = 664). Several hypothesized risk and protective factors for developing or overcoming pathological gaming were measured, including weekly amount of game play, impulsivity, social competence, depression, social phobia, anxiety, and school performance. The prevalence of pathological gaming was similar to that in other countries (∼9%). Greater amounts of gaming, lower social competence, and greater impulsivity seemed to act as risk factors for becoming pathological gamers, whereas depression, anxiety, social phobias, and lower school performance seemed to act as outcomes of pathological gaming. This study adds important information to the discussion about whether video game "addiction" is similar to other addictive behaviors, demonstrating that it can last for years and is not solely a symptom of comorbid disorders.

    bleeding, rate of intra-abdominal abscess, quality of life, cost analysis). We used a random-effects model for all analyses. We calculated the risk ratio (RR) for dichotomous outcomes, and the mean difference (MD) for continuous outcomes (using PG as the reference) with 95% confidence intervals (CI) as a measure of variability. We included 10 RCTs that enrolled a total of 1629 participants. The characteristics of all studies matched the requirements to compare the two types of surgical reconstruction following pancreatoduodenectomy. All studies reported incidence of postoperative pancreatic fistula (the main complication) and postoperative mortality.Overall, the risk of bias in included studies was high; only one included study was assessed at low risk of bias.There was little or no difference between PJ and PG in overall risk of postoperative pancreatic fistula (PJ 24.3%; PG 21.4%; RR 1.19, 95% CI 0.88 to 1.62; 7 studies; low-quality evidence). Inclusion of studies that clearly distinguished clinically significant pancreatic fistula resulted in us being uncertain whether PJ improved the risk of pancreatic fistula when compared with PG (19.3% versus 12.8%; RR 1.51, 95% CI 0.92 to 2.47; very low-quality evidence). PJ probably has little or no difference from PG in risk of postoperative mortality (3.9% versus 4.8%; RR 0.84, 95% CI 0.53 to 1.34; moderate-quality evidence).We found low-quality evidence that PJ may differ little from PG in length of hospital stay (MD 1.04 days, 95% CI -1.18 to 3.27; 4 studies, N = 502) or risk of surgical re-intervention (11.6% versus 10.3%; RR 1.18, 95% CI 0.86 to 1.61; 7 studies, N = 1263). We found moderate-quality evidence suggesting little difference between PJ and PG in terms of risk of any surgical complication (46.5% versus 44.5%; RR 1.03, 95% CI 0.90 to 1.18; 9 studies, N = 1513). PJ may slightly improve the risk of postoperative bleeding (9.3% versus 13.8%; RR 0.69, 95% CI: 0.51 to 0.93; low-quality evidence; 8 studies, N = 1386), but

    Because the islets of Langerhans are more prevalent in the body and tail of the pancreas, distal pancreatectomy (DP) is believed to increase the likelihood of developing new onset diabetes mellitus (NODM). To determine whether the development of postoperative diabetes was more prevalent in patients undergoing DP or Whipple procedure, 472 patients undergoing either a DP (n = 122) or Whipple (n = 350), regardless of underlying pathology, were analyzed at one month postoperatively. Insulin or oral hypoglycemic requirements were assessed and patients were stratified into preoperative diabetic status: NODM or preexisting diabetes. A retrospective chart review of the 472 patients between 1996 and 2014 showed that the total rate of NODM after Whipple procedure was 43 per cent, which was not different from patients undergoing DP (45%). The incidence of preoperative diabetes was 12 per cent in patients undergoing the Whipple procedure and 17 per cent in the DP cohort. Thus, the overall incidence of diabetes after Whipple procedure was 54 and 49 per cent in the DP group. The development of diabetes was unrelated to the type of resection performed. Age more than 65 and Caucasian ethnicity were associated with postoperative diabetes regardless of the type of resection performed.

    Gastric surgery may be performed for the treatment of a variety of benign and malignant diseases of the upper gastrointestinal tract, including peptic ulcers and gastric carcinoma. Radiographic studies with water-soluble contrast agents often are obtained to rule out leaks, obstruction, or other acute complications during the early postoperative period. Barium studies may also be obtained to evaluate for anastomotic strictures or ulcers, bile reflux gastritis, recurrent tumor, or other chronic complications during the late postoperative period. Cross-sectional imaging studies such as CT are also helpful for detecting abscesses or other postoperative collections, recurrent or metastatic tumor, or less common complications such as afferent loop syndrome or gastrojejunal intussusception. It is important for radiologists to be familiar not only with the radiographic findings associated with these various abnormalities but also with the normal appearances of the postoperative stomach on radiographic examinations, so that such appearances are not mistaken for pseudoleaks or other postoperative complications. The purpose of this article is to describe the normal postsurgical anatomy after the most commonly performed operations (including partial gastrectomy, esophagogastrectomy and gastric pull-through, and total gastrectomy and esophagojejunostomy) and to review the acute and chronic complications, normal postoperative findings, and major abnormalities detected on radiographic examinations in these patients.

    Full Text Available ObjectiveTo investigate whether blood lipid control can delay the progression of asymptomatic gallstones and reduce the risk of cholecystectomy in patients with gallstones and hyperlipidemia, as well as the influence of hyperlipidemia on postoperative pain after cholecystectomy. MethodsA total of 153 patients with asymptomatic gallstones and hyperlipidemia who underwent physical examination from February 2013 to February 2015 were enrolled and randomly divided into experimental group with 72 patients and control group with 81 patients. The patients in the experimental group were given blood lipid control via diet, exercise, and drugs, and according to fasting triglyceride (TG and total cholesterol (TC after 3 months, these patients were further divided into normal blood lipid group with 47 patients and abnormal blood lipid group with 25 patients. All the patients were followed up for 2 years with an interval of 3 months. The surgical indications for laparoscopic cholecystectomy were persistent pain in the gallbladder or more than 3 times of gallbladder discomfort within the past one month. A subgroup analysis was performed based on the number and size of gallstones to evaluate the risk of cholecystectomy. A numerical pain scale was used to assess the improvement in pain during hospitalization and at 3 and 6 months after surgery. The t-test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between three groups, and the Bonferroni test was used for further comparison between any two groups. The chi-square test was used for comparison of categorical data between groups. ResultsThe normal blood lipid group had a significantly lower rate of cholecystectomy than the abnormal blood lipid group and the control group (23.4% vs 68.8%/70.4%, χ2=2772, P<0.01. The patients in the normal blood lipid group had moderate pain during hospitalization, while those in the abnormal blood lipid

    According to current recommendations a multimodal approach is believed to be the gold standard for postoperative pain treatment in children. However, several surveys in the last few years demonstrated that postoperative pain in children is still a serious problem, mainly because opioids are avoided. One of the reasons for this is the fear of severe adverse events following opioid administration. Tramadol is a weak mu-opioid agonist and inhibits reuptake of noradrenaline and serotonin (5HT). Because of a relatively wide therapeutic window and a ceiling effect with a lower risk for severe adverse events (for example respiratory depression) tramadol is a widely used opioid in children. However, the exact efficacy and occurrence of adverse events following tramadol (in comparison with placebo or other opioids) for postoperative pain treatment in children and adolescents are currently not clear. To assess the effectiveness and side effect profile of tramadol for postoperative pain relief in children and adolescents undergoing different surgical procedures. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 6), MEDLINE via PubMed (January 1966 to July 2014) and EMBASE via Ovid (January 1947 to July 2014). There were no restrictions regarding language or date of publication. The reference lists of all included trials were checked for additional studies. All randomised controlled clinical trials investigating the perioperative administration of tramadol compared to placebo or other opioids for postoperative pain treatment in children and adolescents were included. Three review authors independently assessed the study eligibility, performed the data extraction and assessed the risk of bias of included trials. Twenty randomised controlled trials involving 1170 patients were included in this systematic review. The overall risk of bias in included trials was assessed as unclear, because

    Despite technical advances, bile leak remains a significant complication after hepatectomy. The current study uses a targeted multi-institutional dataset to characterize perioperative factors that are associated with bile leakage after hepatectomy to better understand the impact of bile leak on morbidity and mortality. Adult patients in the 2014-2015 ACS NSQIP targeted hepatectomy dataset were linked to the ACS NSQIP PUF dataset. Bivariable and multivariable regression analyses were used to assess the associations between clinical factors and post-hepatectomy bile leak. Of 6859 patients, 530 (7.7%) had a postoperative bile leak. Proportion of bile leaks was significantly greater in patients after major compared to minor hepatectomy (12.6 vs. 5.1%, p leak was significantly greater in patients after major hepatectomy who had concomitant enterohepatic reconstruction (31.8 vs. 10.1%, p leaks (6.0 vs. 1.7%, p leak was independently associated with increased risk of postoperative morbidity (OR = 4.55; 95% CI 3.72-5.56; p leak was not independently associated with increased risk of postoperative mortality (p = 0.262). Major hepatectomy and enterohepatic biliary reconstruction are associated with significantly greater rates of bile leak after liver resection. Bile leak is independently associated with significant postoperative morbidity. Mitigation of bile leak is critical in reducing morbidity and mortality after liver resection.

    Postoperative myocardial injury (PMI) is a strong predictor of mortality after noncardiac surgery. PMI is believed to be attributable to coronary artery disease (CAD), yet its etiology is largely unclear. We aimed to quantify the prevalence of significant CAD in patients with and without PMI using coronary computed tomography angiography (CCTA). This prospective cohort study included patients of 60 years or older without a history of cardiac disease and with and without PMI after intermediate- to high-risk noncardiac surgery. PMI was defined as any serum troponin I level ≥60 ng/L on the first 3 postoperative days. Main exclusion criteria were known cardiac disease and postoperative ischemic symptoms or electrocardiography abnormalities. Noninvasive imaging consisted of a postoperative CCTA. Main outcome was CAD defined as >50% coronary stenosis on CCTA. The analysis included 66 patients. Median peak troponin levels in the PMI (n = 46) and control group (n = 20) were 150 (interquartile range, 120-298) vs 15 (interquartile range, 10-31) ng/L (P PMI (50%) vs 3 without PMI (15%; relative risk, 3.3; 95% confidence interval, 1.1-9.8). Remarkably, pulmonary embolism was present in 15 patients with PMI (33%) versus in 4 without PMI (20%; relative risk, 1.6; 95% confidence interval, 0.6-4.3). None of the patients died within 30 days. In patients without a history of cardiac disease, PMI after noncardiac surgery was associated with CAD. In addition, a clinically silent pulmonary embolism was found in one-third of patients with PMI. This urges further research to improve clinical workup using imaging and may have important clinical implications.

    Purpose: Postoperative radiotherapy (XRT) increases survival in high-risk prostate cancer patients. Approximately 50% of patients on long-term follow-up relapse despite adjuvant XRT and the predominant site of failure remains local. Four consensus guidelines define postoperative clinical target volume (CTV) in prostate cancer. We explore the possibility that inadequate CTV coverage is an important cause of local failure. This study evaluates the utility of preoperative magnetic resonance imaging (MRI) in defining prostate bed CTV. Methods and Materials: Twenty prostate cancer patients treated with postoperative XRT who also had preoperative staging MRI were included. The four guidelines were applied and the CTVs were expanded to create planning target volumes (PTVs). Preoperative MRIs were fused with postoperative planning CT scans. MRI-based prostate and gross visible tumors were contoured. Three-dimensional (3D) conformal four- and six-field XRT plans were developed and dose–volume histograms analyzed. Subtraction analysis was conducted to assess the adequacy of prostate/gross tumor coverage. Results: Gross tumor was visible in 18 cases. In all 20 cases, the consensus CTVs did not fully cover the MRI-defined prostate. On average, 35% of the prostate volume and 32% of the gross tumor volume were missed using six-field 3D treatment plans. The entire MRI-defined gross tumor volume was completely covered in only two cases (six-field plans). The expanded PTVs did not cover the entire prostate bed in 50% of cases. Prostate base and mid-zones were the predominant site of inadequate coverage. Conclusions: Current postoperative CTV guidelines do not adequately cover the prostate bed and/or gross tumor based on preoperative MRI imaging. Additionally, expanded PTVs do not fully cover the prostate bed in 50% of cases. Inadequate CTV definition is likely a major contributing factor for the high risk of relapse despite adjuvant XRT. Preoperative imaging may lead to more

    A total of 88 cases of 81 patients with spontaneous pneumothorax treated at the hospital from March 1992 to August 2001 were subjected to a study of examining preoperative chest CT and thoracographic findings from the standpoint of postoperative recurrence. Preoperative chest CT and thoracography were conducted in 82 cases and 41 cases (including 25 cases with continuous air leakage), respectively. Eight (9.1%) patients developed recurrence of pneumothorax, and three patients of them underwent reoperation. Considering the intraoperative findings, newly formed bullae appeared to be a cause of recurrence. Resulting from these examinations, we conclude that it is difficult to predict the risk factor for postoperative recurrence at this time, in addition, it is important that the area of air leakage can be confirmed by thoracoscopic findings.

    There has been no consensus on the best catheterization strategy for the management of postoperative urinary retention. A prospective randomized trial was undertaken to establish the best practice guidelines for the management of postoperative urinary retention. The authors also evaluated the contemporary incidence of urinary retention following different categories of general surgery and examined risk factors associated with its occurrence. All patients who underwent elective inpatient surgery between January 2002 and June 2003 were recruited into the study. Patients who developed postoperative urinary retention were randomized to either having in-out catheterization or placement of an indwelling catheter for 24 h after surgery. A total of 1448 patients was recruited. The overall incidence of urinary retention was 4.1% (n = 60). Significant risk factors associated with postoperative urinary retention included old age, anorectal procedures and use of spinal anaesthesia. Comparison of re-catheterization and urinary tract infection rates between patients who were treated with in-out versus overnight catheterization found no significant differences. Postoperative urinary retention should be managed by in-out catheterization. Indwelling catheterization for 24 h appeared to bestow no additional benefits. The incidence of urinary retention increases with age, anorectal procedures and the use of spinal anaesthesia.

    To analyze factors associated with metastases, prostate cancer-specific mortality, and all-cause mortality in pN1 patients. We analyzed 3,642 radical prostatectomy patients within the Shared Equal Access Regional Cancer Hospital (SEARCH) database. Pathologic Gleason grade, number of lymph nodes (LN) removed, and first postoperative prostate-specific antigen (PSA) (PSA. Of 3,642 patients, 124 (3.4%) had pN1. There were 71 (60%) patients with 1 positive LN, 32 (27%) with 2 positive LNs, and 15 (13%) with ≥3. Among men with pN1, first postoperative PSA wasPSA ≥0.2 ng/ml (P = 0.005) were associated with metastases. First postoperative PSA ≥0.2ng/ml was associated with metastasis on multivariable analysis (P = 0.046). Log-rank analysis revealed a more favorable metastases-free survival in patients with a first postoperative PSAPSAPSA ≥0.2ng/ml were more likely to develop metastases. First postoperative PSA may be useful in identifying pN1 patients who harbor distant disease and aid in secondary treatment decisions. Copyright © 2018 Elsevier Inc. All rights reserved.

    The authors report the personal techniques and the results of CT-guided percutaneous drainage of postoperative abdominal fluid collections. CT-guided percutaneous drainage offers many advantages over surgery: it is less invasive, can be repeated and requires no anesthesia, there are not surgery-related risks and lower morbidity and mortality rates. Moreover, subsequent hospitalization is shorter and costs are consequently reduced. The authors conclude that CT-guided percutaneous drainage is the method of choice in the treatment of postoperative abdominal fluid collections [it

    The aim of this study was to compare intensity-modulated radiation therapy (IMRT) with 3D conformal technique (3D-CRT), with respect to target coverage and irradiation of organs at risk for high dose postoperative radiotherapy (PORT) of the prostate fossa. 3D-CRT and IMRT treatment plans were compared with respect to dose to the rectum and bladder. The dosimetric comparison was carried out in 15 patients considering 2 different scenarios: (1) exclusive prostate fossa irradiation, and (2) pelvic node irradiation followed by a boost on the prostate fossa. In scenario (1), a 3D-CRT plan (box technique) and an IMRT plan were calculated and compared for each patient. In scenario (2), 3 treatment plans were calculated and compared for each patient: (a) 3D-CRT box technique for both pelvic (prophylactic nodal irradiation) and prostate fossa irradiation (3D-CRT only); (b) 3D-CRT box technique for pelvic irradiation followed by an IMRT boost to the prostatic fossa (hybrid 3D-CRT and IMRT); and (c) IMRT for both pelvic and prostate fossa irradiation (IMRT only). For exclusive prostate fossa irradiation, IMRT significantly reduced the dose to the rectum (lower Dmean, V50%, V75%, V90%, V100%, EUD, and NTCP) and the bladder (lower Dmean, V50%, V90%, EUD and NTCP). When prophylactic irradiation of the pelvis was also considered, plan C (IMRT only) performed better than plan B (hybrid 3D-CRT and IMRT) as respect to both rectum and bladder irradiation (reduction of Dmean, V50%, V75%, V90%, equivalent uniform dose [EUD], and normal tissue complication probability [NTCP]). Plan (b) (hybrid 3D-CRT and IMRT) performed better than plan (a) (3D-CRT only) with respect to dose to the rectum (lower Dmean, V75%, V90%, V100%, EUD, and NTCP) and the bladder (Dmean, EUD, and NTCP). Postoperative IMRT in prostate cancer significantly reduces rectum and bladder irradiation compared with 3D-CRT.

    Purpose: To determine the role of adjuvant postoperative radiotherapy (RT) following radical prostatectomy (RP) in a group of patients with pathologic Stage T3/4 adenocarcinoma of the prostate followed for a median of 10 years after treatment. Methods and Materials: Between 1970 and 1983, 159 patients underwent RP for newly diagnosed adenocarcinoma of the prostate and were found to have pathologic Stage T3/4 tumors. Forty-six received adjuvant RT and 113 did not. Radiotherapy usually consisted of 45-50 Gy to the whole pelvis followed by a boost to the prostate bed of 10-15 Gy, to a total dose of 55-65 Gy. Patients were analyzed with respect to survival, disease-free survival, local control, and freedom from distant metastases. A rising prostate-specific antigen in the absence of other evidence of relapse was scored as a separate category of recurrence. Results: Both groups of patients have been followed for a median of 10 years. The actuarial survival at 10 and 15 years was 62% and 62% for the RT group compared to 52% and 37%, respectively, for the RP group (p = 0.18). The disease-free survival for the RT group was 55% and 48% at 10 and 15 years, respectively, compared to 37% and 33% for the RP group (p = 0.16). Similarly, there was no difference in the rate of distant metastases between the two groups. In contrast, the local relapse rate was significantly reduced by the addition of postoperative radiotherapy. The actuarial local control rate at 10 and 15 years was 92% and 82%, respectively, for the RT group vs. 60% and 53% for the RP group (p 0.002). Conclusions: While postoperative pelvic RT significantly improves local control compared to RP alone for pathologic Stage T3/4 prostate cancer, it has no impact on distant metastases and consequently does not improve survival. These data are consistent with the conclusion that many patients with pathologic Stage T3/4 prostate cancer have occult metastases at presentation and will not be cured by local therapies alone

    The aims of this study were to identify risk factors for the recurrence of hallux valgus deformity and to clarify whether recurrence after surgery to treat hallux valgus can be predicted using radiographic parameters assessed on immediate postoperative non-weight-bearing radiographs. A proximal chevron osteotomy combined with a distal soft-tissue procedure was performed by a single surgeon to treat moderate to severe hallux valgus deformity in 93 patients (117 feet). The feet were grouped according to nonrecurrence or recurrence. Changes in the hallux valgus angle, the intermetatarsal angle, and sesamoid position over time were analyzed by comparing values measured during each postoperative period. The relative risks of recurrence as indicated by preoperative and postoperative radiographic parameters were determined. Twenty (17.1%) of the 117 feet showed hallux valgus recurrence at the time of the last follow-up. The hallux valgus angle and the intermetatarsal angle stabilized at 6 months after surgery in the nonrecurrence group. An immediate postoperative hallux valgus angle of ≥8°, an immediate postoperative sesamoid position of grade 4 or greater, a preoperative metatarsus adductus angle of ≥23°, and a preoperative hallux valgus angle of ≥40° were significantly associated with recurrence. Recurrence of hallux valgus after a proximal chevron osteotomy can be reliably predicted from immediate postoperative non-weight-bearing radiographs. Therapeutic Level III.

    To investigate whether patients treated for a localized prostate cancer (PCa) require a radical prostatectomy followed by postoperative radiotherapy or exclusive radiotherapy, in the modern era of image guided IMRT. 178 patients with PCa were referred for daily exclusive image guided IMRT (IG-IMRT) using an on-line 3D ultra-sound based system and 69 patients were referred for postoperative IMRT without image guidance after radical prostatectomy (RP + IMRT). Patients were matched in a 1:1 ratio according to their baseline risk group before any treatment. Late toxicity was scored using the CTV v3.0 scale. Biochemical failure was defined as a postoperative PSA ≤ 0.1 ng/mL followed by 1 consecutive rising PSA for the postoperative group of patients and by the Phoenix definition (nadir + 2 ng/mL) for the group of patients treated with exclusive radiotherapy. A total of 98 patients were matched (49:49). From the start of any treatment, the median follow-up was 56.6 months (CI 95% = [49.6-61.2], range [18.2-115.1]). No patient had late gastrointestinal grade ≥ 2 toxicity in the IG-IMRT group vs. 4% in the RP + IMRT group. Forty two percent of the patients in both groups had late grade ≥ 2 genitourinary toxicity. The 5-year FFF rates in the IG-IMRT group and in the RP + IMRT groups were 93.1% [80.0-97.8] and 76.5% [58.3-87.5], respectively (p = 0.031). Patients with a localized PCa treated with IG-IMRT had better oncological outcome than patients treated with RP + IMRT. Further improvements in postoperative IMRT using image guidance and dose escalation are urgently needed

    Antimicrobial Resistance is threatening our ability to treat common infectious diseases and overuse of antimicrobials to treat human infections in hospitals is accelerating this process. Clinical Decision Support Systems (CDSSs) have been proven to enhance quality of care by promoting change in prescription practices through antimicrobial selection advice. However, bypassing an initial assessment to determine the existence of an underlying disease that justifies the need of antimicrobial therapy might lead to indiscriminate and often unnecessary prescriptions. From pathology laboratory tests, six biochemical markers were selected and combined with microbiology outcomes from susceptibility tests to create a unique dataset with over one and a half million daily profiles to perform infection risk inference. Outliers were discarded using the inter-quartile range rule and several sampling techniques were studied to tackle the class imbalance problem. The first phase selects the most effective and robust model during training using ten-fold stratified cross-validation. The second phase evaluates the final model after isotonic calibration in scenarios with missing inputs and imbalanced class distributions. More than 50% of infected profiles have daily requested laboratory tests for the six biochemical markers with very promising infection inference results: area under the receiver operating characteristic curve (0.80-0.83), sensitivity (0.64-0.75) and specificity (0.92-0.97). Standardization consistently outperforms normalization and sensitivity is enhanced by using the SMOTE sampling technique. Furthermore, models operated without noticeable loss in performance if at least four biomarkers were available. The selected biomarkers comprise enough information to perform infection risk inference with a high degree of confidence even in the presence of incomplete and imbalanced data. Since they are commonly available in hospitals, Clinical Decision Support Systems could

    OBJECTIVES: Inhalational anesthetics are bronchodilators with immunomodulatory effects. We sought to determine the effect of inhalational anesthetic dose on risk of severe postoperative respiratory complications. DESIGN: Prospective analysis of data on file in surgical cases between January 2007...... with endotracheal intubation. INTERVENTIONS: Median effective dose equivalent of inhalational anesthetics during surgery (derived from mean end-tidal inhalational anesthetic concentrations). MEASUREMENTS AND MAIN RESULTS: Postoperative respiratory complications occurred in 6,979 of 124,497 cases (5.61%). High...... inhalational anesthetic dose of 1.20 (1.13-1.30) (median [interquartile range])-fold median effective dose equivalent versus 0.57 (0.45-0.64)-fold median effective dose equivalent was associated with lower odds of postoperative respiratory complications (odds ratio, 0.59; 95% CI, 0.53-0.65; p

    2012-02-03

    BACKGROUND: Patients with Ulcerative Colitis (UC) have inherent prothrombotic tendencies. It is unknown whether this necessitates the use of additional perioperative anti-thrombotic prophylaxis when such patients require major surgery. METHODS: The postoperative courses of 79 patients with UC undergoing 180 major abdominal and pelvic operations were examined for clinical and radiological evidence of venous thrombosis. Eighteen patients with Familial Adenomatous Polyposis (FAP) having surgery (35 operations) of similar magnitude were also studied. Standard anti-thrombosis prophylaxis was utilised in all patients. RESULTS: Nine patients with UC were clinically suspected of developing postoperative venous thrombosis, but only three (3.8%) had their diagnosis confirmed radiologically (all had a pulmonary embolus). Therefore, the overall postoperative thrombosis rate, on an intention to treat basis, was 1.7% (3\\/180). No patient with FAP developed significant venous thrombosis. CONCLUSION: Standard perioperative antithrombotic modalities are sufficient to maintain any potential increase in postoperative thrombotic risk at an acceptable level in patients with UC undergoing operative intervention.

    Throughout the course of history, gambling has been a popular activity across most cultures. In the United States, gambling has transitioned from early acceptance to prohibition to widespread proliferation. For most, gambling is a relaxing and recreational activity; however, for some individuals gambling becomes more than harmless fun. The most severe form of gambling, pathological gambling, is recognized as a mental health disorder. Pathological gambling is currently classified as an impulse control disorder in the DSM-IV-TR, but it shares many important features with substance use disorders, especially in terms of diagnostic criteria, clinical course, and treatment. Consequently, the DSM-V Task Force has suggested that pathological gambling be reclassified and included in a new category entitled "Addiction and Related Disorders." The category would include both substance-related and non-substance/behavioral addictions. This article provides a general overview of some of the available literature regarding pathological gambling and includes the presentation of a number of relevant topics including etiology, risk factors, comorbidity, prevention, and treatment. However, as with most complex, multifaceted, and multidimensional phenomena, more research is needed in order to improve both prevention and treatment efforts for pathological gambling.

    Ureteral stents are commonly placed before colorectal resection to assist in identification of ureters and prevent injury. Acute kidney injury (AKI) is a common cause of morbidity and increased cost following colorectal surgery. Although previously associated with reflex anuria, prophylactic stents have not been found to increase AKI. We sought to determine the impact of ureteral stents on the incidence of AKI following colorectal surgery. All patients undergoing colon or rectal resection at a single institution between 2005 and 2015 were reviewed using American College of Surgeons National Surgical Quality Improvement Program dataset. AKI was defined as a rise in serum creatinine to ≥ 1.5 times the preoperative value. Univariate and multivariate regression analyses were performed to identify independent predictors of AKI. 2910 patients underwent colorectal resection. Prophylactic ureteral stents were placed in 129 patients (4.6%). Postoperative AKI occurred in 335 (11.5%) patients during their hospitalization. The stent group demonstrated increased AKI incidence (32.6% vs. 10.5%; p colorectal surgery including age, procedure duration, and ureteral stent placement. Prophylactic ureteral stents independently increased AKI risk when placed prior to colorectal surgery. These data demonstrate increased morbidity and hospital costs related to usage of stents in colorectal surgery, indicating that placement should be limited to patients with highest potential benefit.

  16. Radiation Protection in the intra-and post-operative diagnosis of the sentinel lymph node (SLN)

    Kopp, J.; Wengenmair, H.

    2002-01-01

    Radioactive marked colloids have gained wide acceptance in the diagnosis of sentinel lymph nodes (SLN) compared to dyes. Therefore various aspects of radiation protection have to be taken into account. Application and preoperative diagnosis usually takes place in a nuclear medicine ward where the personnel is highly trained in the use of radioactive materials. Intra-and postoperative diagnosis involves personnel in the operating cabinet and the pathology that is not necessarily radiation protected and trained and therefore should not exceed a yearly dose of ImSv. Organizational problems would arise if all those people have to be included into a full radiation protection program and supervision. The expected exposure has to considered to decide about the necessary actions that have to be taken. Additionally the exposure of the patient has to be estimated to assess the corresponding radiation risk. The reason for a wide resulting variation of organ dose are the uncertainties of the various methods of dose calculation, the individual differences of the patients (e. g. size of mamma) and the differences in surgical removal of radioactivity contaminated tissue.

    Surgical site infections (SSI) are a substantial concern for cesarean deliveries in which a surgical site complication is most unwelcome for a mother with a new infant. Steps taken pre- and post-operatively to reduce the number of complications may be of substantial benefit clinically, economically, and psychologically. A risk-based approach to incision management was developed and implemented for all cesarean deliveries at our institution. A number of incremental interventions for low-risk and high-risk patients including pre-operative skin preparations, standardized pre- and post-operative protocols, post-operative nanocrystalline silver anti-microbial barrier dressings, and incisional negative pressure wound therapy (NPWT) were implemented sequentially over a 5-y period. A systematic clinical chart review of 4,942 patients spanning all cesarean deliveries between 2007-2012 was performed to determine what effects the interventions had on the rate of SSI for cesarean deliveries. The percentage of SSI was reduced from 2.13% (2007) to 0.10% (2012) (poperative SSIs were avoided: A total cost saving of nearly $5,000,000. Applying a clinical algorithm for assessing the risk of surgical site complication and making recommendations on pre-operative and post-operative incision management can result in a substantial and sustainable reduction in cesarean SSI.

    Møller, Ann; Tønnesen, Hanne

    2006-01-01

    Smoking is a well-known risk factor for perioperative complications. Smokers experience an increased incidence of respiratory complications during anaesthesia and an increased risk of postoperative cardiopulmonary complications, infections and impaired wound healing. Smokers have a greater risk...... of postoperative intensive care admission. Even passive smoking is associated with increased risk at operation. Preoperative smoking intervention 6-8 weeks before surgery can reduce the complications risk significantly. Four weeks of abstinence from smoking seems to improve wound healing. An intensive, individual...... approach to smoking intervention results in a significantly better postoperative outcome. Future research should focus upon the effect of a shorter period of preoperative smoking cessation. All smokers admitted for surgery should be informed of the increased risk, recommended preoperative smoking cessation...

    Purpose: The purpose of this study was to prospectively and directly compare diagnostic capabilities of whole-body integrated FDG-PET/CT and standard radiologic examination for assessment of recurrence in postoperative non-small cell lung cancer (NSCLC) patients. Materials and methods: A total of 92 consecutive pathologically diagnosed NSCLC patients (65 males, 27 females; mean age, 71 years) underwent pathologically and surgically proven complete resection, followed by prospective whole-body FDG-PET/CT and standard radiological examinations. Final diagnosis of recurrence was based on the results of more than 1 year of follow-up and/or pathological examinations. On both methods, the probability of recurrence was assessed in each patient by using a five-point visual scoring system, and the each final diagnosis was made by consensus between two readers. Kappa analyses were performed to determine inter-observer agreement for both methods, and ROC analyses were used to compare capability of the two methods for assessment of postoperative recurrence on a per-patient basis. Sensitivity, specificity and accuracy were also compared between PET/CT and standard radiological examination by means of McNemar's test. Results: All inter-observer agreements were almost perfect (integrated PET/CT: κ = 0.89; standard radiological examination: κ = 0.81). There were no statistically significant differences in area under the curve, sensitivity, specificity and accuracy between integrated FDG-PET/CT and standard radiologic examinations (p > 0.05). Conclusion: Integrated FDG-PET/CT can be used for assessment of postoperative recurrence in NSCLC patients with accuracy as good as that of standard radiological examinations.

    Purpose: The purpose of this study was to prospectively and directly compare diagnostic capabilities of whole-body integrated FDG-PET/CT and standard radiologic examination for assessment of recurrence in postoperative non-small cell lung cancer (NSCLC) patients. Materials and methods: A total of 92 consecutive pathologically diagnosed NSCLC patients (65 males, 27 females; mean age, 71 years) underwent pathologically and surgically proven complete resection, followed by prospective whole-body FDG-PET/CT and standard radiological examinations. Final diagnosis of recurrence was based on the results of more than 1 year of follow-up and/or pathological examinations. On both methods, the probability of recurrence was assessed in each patient by using a five-point visual scoring system, and the each final diagnosis was made by consensus between two readers. Kappa analyses were performed to determine inter-observer agreement for both methods, and ROC analyses were used to compare capability of the two methods for assessment of postoperative recurrence on a per-patient basis. Sensitivity, specificity and accuracy were also compared between PET/CT and standard radiological examination by means of McNemar's test. Results: All inter-observer agreements were almost perfect (integrated PET/CT: {kappa} = 0.89; standard radiological examination: {kappa} = 0.81). There were no statistically significant differences in area under the curve, sensitivity, specificity and accuracy between integrated FDG-PET/CT and standard radiologic examinations (p > 0.05). Conclusion: Integrated FDG-PET/CT can be used for assessment of postoperative recurrence in NSCLC patients with accuracy as good as that of standard radiological examinations.

    Epiretinal membranes (ERM) are macular disorders leading to loss of vision and metamorphopsia. Vitrectomy with membrane peeling displays the gold standard of care. Aim of this study was to assess risk factors for postoperative intraretinal cystoid changes in a study population randomized for balanced salt solution and air-tamponade at the end of surgery. A prospective randomized study, including 69 eyes with idiopathic ERM. Standard 23-gauge three-port pars plana vitrectomy with membrane peeling, using intraoperative optical coherence tomography (OCT), was performed. Randomization for BSS and air-tamponade was performed prior to surgery. Best-corrected visual acuity improved from 32.9 letters to 45.1 letters 3 months after surgery. Presence of preoperative intraretinal cystoid changes was found to be the only risk factor for presence of postoperative intraretinal cystoid changes 3 months after surgery (p = 0.01; odds ratio: 8.0). Other possible risk factors such as combined phacoemulsification with 23G-ppv and membrane peeling (p = 0.16; odds ratio: 2.4), intraoperative subfoveal hyporeflective zones (p = 0.23; odds ratio: 2.6), age over 70 years (p = 0.29; odds ratio: 0.5) and air-tamponade (p = 0.59; odds ratio: 1.5) were not found to be significant. There is strong evidence that preoperative intraretinal cystoid changes lead to smaller benefit from surgery. © 2018 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    To evaluate retrospectively the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiotherapy (CRT) in advanced gastric cancer. Between January 2000 and December 2006, 80 patients with advanced gastric cancer who received postoperative concurrent CRT were included. Pathological staging was IB-II in 9%, IIIA in 38%, IIIB in 33%, and IV in 21%. Radiotherapy consisted of 45 Gy of radiation. Concurrent chemotherapy consisted of a continuous intravenous infusion of 5-fluorouracil and leucovorin on the first 4 days and last 3 days of radiotherapy. The median follow-up period was 48 months (range, 3 to 83 months). The 5-year overall survival, disease-free survival, and locoregional recurrence-free survivals were 62%, 59%, and 80%, respectively. In the multivariate analysis, significant factors for disease-free survival were T stage (hazard ratio [HR], 0.278; p = 0.038), lymph node dissection extent (HR, 0.201; p = 0.002), and maintenance oral chemotherapy (HR, 2.964; p = 0.004). Locoregional recurrence and distant metastasis occurred in 5 (6%) and 18 (23%) patients, respectively. Mixed failure occurred in 10 (16%) patients. Grade 3 leukopenia and thrombocytopenia were observed in 4 (5%) and one (1%) patient, respectively. Grade 3 nausea and vomiting developed in 8 (10%) patients. Intestinal obstruction developed in one (1%). The survival outcome of the postoperative CRT in advanced gastric cancer was similar to those reported previously. Our postoperative CRT regimen seems to be a safe and effective method, reducing locoregional failure without severe treatment toxicity in advanced gastric cancer patients.

    This study aims to describe laparoscopic reoperation (LSR) and compare its outcomes with transabdominal reoperation (TAR) for treating Hirschsprung's disease (HD). Eighteen patients with HD underwent reoperation for recurring constipation due to residual aganglionosis and transition zone pathology after an initial transanal procedure (LSR, n=10; TAR, n=8). Preoperative, operative and postoperative data were collected through patient follow-ups ranging from 13 to 75months to compare operative characteristics and postoperative outcomes between the two groups. Ten patients underwent laparoscopic reoperation in our institution without major complications. On average, blood loss was significantly lower in the LSR group (mean±standard deviation, 83±32.7mL) than in the TAR group (185±69mL) (P=0.001). The LSR group had a shorter hospitalization time (12±2days) than the TAR group (15±2.1days) (P=0.02). There was no statistically significant difference in incidence of postoperative complications between the two groups. LSR is safe and technically feasible in HD for recurring constipation due to residual aganglionosis and transition zone pathology, when initial transanal procedure fails. Although RA and TZP can be cured by reoperation, great efforts should be made to diminish the necessity of reoperation. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Laparoscopic distal pancreatectomy (LDP is a safe and reliable treatment for tumors in the body and tail of the pancreas. Postoperative pancreatic fistula (POPF is a common complication of pancreatic surgery. Despite improvement in mortality, the rate of POPF still remains high and unsolved. To identify risk factors for POPF after laparoscopic distal pancreatectomy, clinicopathological variables on 120 patients who underwent LDP with stapler closure were retrospectively analyzed. Univariate and multivariate analyses were performed to identify risk factors for POPF. The rate of overall and clinically significant POPF was 30.8% and13.3%, respectively. Higher BMI (≥25kg/m2 (p-value = 0.025 and longer operative time (p-value = 0.021 were associated with overall POPF but not clinically significant POPF. Soft parenchymal texture was significantly associated with both overall (p-value = 0.012 and clinically significant POPF (p-value = 0.000. In multivariable analyses, parenchymal texture (OR, 2.933, P-value = 0.011 and operative time (OR, 1.008, P-value = 0.022 were risk factors for overall POPF. Parenchymal texture was an independent predictive factor for clinically significant POPF (OR, 7.400, P-value = 0.001.

    Intestinal-type gastric cancer (GC) still ranks among the high-incidence, highly lethal malignancies. Atrophic gastritis is the cancerization field in which GC develops. The current histological reporting formats for gastritis do not include any (atrophy-based) ranking of GC risk. To test the gastritis OLGA-staging (Operative Link for Gastritis Assessment) in prognosticating neoplastic progression. Ninety-three Italian patients were followed up for more than 12 years (range: 144-204 months). Clinical examinations, pepsinogen serology, endoscopy and histology (also assessing Helicobacter pylori status) were performed both at enrolment (T1) and at the end of the follow-up (T2). All invasive or intra-epithelial gastric neoplasia were consistently associated with high-risk (III/IV) OLGA stages. There was a significant inverse correlation between the mean pepsinogen ratio and the OLGA stage (test for trend; P gastritis OLGA-staging conveys relevant information on the clinico-pathological outcome of gastritis and therefore for patient management. According to OLGA-staging and H. pylori-status, gastritis patients could be confidently stratified and managed according to their different cancer risks.

    Ankylosing spondylitis (AS) is a chronic autoimmune spondyloarthropathy that primarily affects the axial spine and hips. Progressive disease leads to pronounced spinal kyphosis, positive sagittal balance, and altered biomechanics. The purpose of this study is to determine the complication profile of patients with AS undergoing total hip arthroplasty (THA). The Medicare sample was searched from 2005 to 2012 yielding 1006 patients with AS who subsequently underwent THA. Risk ratios (RRs) with 95% confidence intervals (CIs) were calculated for 90-day, 2-year, and the final postoperative follow-up for complications including hip dislocation, periprosthetic fracture, wound complication, revision THA, and postoperative infection. Compared to controls, AS patients had an RR of 2.50 (CI, 1.04-5.99) of THA component breakage at 90-days post-operatively and 1.99 (CI, 1.10-3.59) at 2-years. The RR of periprosthetic hip dislocation was elevated at 90 days (1.44; CI, 0.93-2.22) and significantly increased at 2-years (1.67; CI, 1.25-2.23) and overall follow-up (1.49; CI, 1.14-1.93). Similarly, the RR for THA revision was elevated at 90-days (1.46; CI, 0.97-2.18) and significantly increased at 2-years (1.69; CI, 1.33-2.14) and overall follow-up (1.51; CI, 1.23-1.85). Patients with AS are at increased risk for complications after THA. Altered biomechanics from a rigid, kyphotic spine place increased demand on the hip joints. The elevated perioperative and postoperative risks should be discussed preoperatively, and these patients may require increased preoperative medical optimization as well as possible changes in component selection and position to compensate for altered spinopelvic biomechanics.

    Non-penetrating deep sclerectomy (NPDS) can enhance drainage of aqueous humour without disrupting the trabecular endothelial layer, reducing risks of postoperative hypotony and hyphema. This study explores associations of angle morphology with surgical efficacy in eyes with open and obstructed angles. Eighty-nine consecutive eyes undergoing successful NPDS (non-implant, with 0.4 mg/ml mitomycin C and limbus-based two-layer closure) were studied in this institutional review board-approved retrospective quality assurance study. Postoperative complication frequency, intraocular pressure (IOP), glaucoma medications required and acuity were monitored (baseline vs 3, 6, 9, 12 and 18-month postoperative levels), along with 30-2 Humphrey MD and corrected pattern standard deviation (CPSD) (baseline vs 6, 12 and 18-month postoperative values). Preoperative gonioscopy was compared with the subsequent requirement for specific postoperative interventions. IOP at all five postoperative intervals was reduced (22 ± 0.9 to 12 ± 0.5 mm Hg; p<0.0001). No hyphema were observed. Postoperative hypotony (IOP < 4 mm Hg) occurred rarely (8/445; 1.8%). Mean glaucoma medication use dropped from 3.1 ± 0.1 to 0.23 ± 0.1 at 18 months (p<0.0001). Mean 30-2 MD improved by approximately 1.4 dB at 6, 12 and 18 months (p<0.002); CPSD remained stable. Following NPDS, a sustained IOP decrease of 10 mm Hg (45%) was attained, with stable acuity, increased perimetric generalised light sensitivity and 90% reduction in medical therapy requirement. Morbidity risk was associated with narrow gonioscopic angle insertion and synechia, but not with shallow approach or trabecular pigmentation.

    The study aimed to determine if mitral valve repair (MVRR) or bioprosthetic mitral valve replacement (BMVR) without postoperative anticoagulation is associated with a similar risk of thromboembolism and death as anticoagulation. We retrospectively reviewed our 2004-09 experience in 249 MVRR and bioprosthetic replacement patients (53% female; 63 year mean age). Concurrent procedures principally included antiarrhythmic surgery, aortic valve replacement, tricuspid valve repair and coronary bypass grafting. Warfarin therapy was instituted at the discretion of the surgeon. Thirty-day, a period known to have the highest risk of valve-related thromboembolism, outcomes were compared relying on the incidence of stroke and death as surrogates of thromboembolic complications. Intermediate-term survival was compared between the groups using Cox proportional hazard models. The mean follow-up was 2.9 years. Given the non-randomized warfarin use, a propensity score using patient comorbidities and concurrent procedures was created and added to the Cox models. One hundred and ninety-two (77%) patients were discharged on warfarin and 57 (23%) were discharged without warfarin. Thirty-day mortality in patients discharged from the index hospitalization was 1.2% and was similar for the two groups (P = 0.99). Four ischaemic perioperative strokes were detected; 3 in the warfarin group and 1 in the no warfarin group (P = 0.99). Overall survival was 84%, with 84% survival in the warfarin group and 86% in the no warfarin group (P = 0.79). Bleeding complications were comparable between the two groups (P = 0.72). In a multivariate analysis, warfarin was not related to mortality. Despite current guidelines recommending postoperative anticoagulation following MVRR or bioprosthetic replacement, the avoidance of warfarin does not increase perioperative complications and has no impact on intermediate survival. Accordingly, a prospective randomized study to adjudicate the role of extended warfarin

    To evaluate the pathologic response of cervical carcinoma to external beam radiotherapy (EBRT) and high dose rate brachytherapy (HDRB) and outcome. Between 1992 and 2001, 67 patients with cervical carcinoma were submitted to preoperative radiotherapy. Sixty-five patients were stage IIb. Preoperative treatment included 45 Gy EBRT and 12 Gy HDRB. Patients were submitted to surgery after a mean time of 82 days. Lymphadenectomy was performed in 81% of patients. Eleven patients with residual cervix residual disease on pathological specimen were submitted to 2 additional insertions of HDRB. median follow up was 72 months. Five-year cause specific survival was 75%, overall survival 65%, local control 95%. Complete pelvic pathological response was seen in 40%. Surgery performed later than 80 days was associated with pathological response. Pelvic nodal involvement was found in 12%. Complete pelvic pathological response and negative lymphnodes were associated with better outcome (p = .03 and p = .005). Late grade 3 and 4 urinary and intestinal adverse effects were seen in 12 and 2% of patients. Time allowed between RT and surgery correlated with pathological response. Pelvic pathological response was associated with improved outcome. Postoperative additional HDRB did not improve therapeutic results. Treatment was well tolerated

    Meniscectomy (MX) of sheep induces a well-established animal model of human osteoarthritis (OA). This study compared the clinical (lameness) and pathological outcomes of unilateral, complete medial MX vs two less traumatic and more easily performed meniscal destabilisation procedures. Four-year old wethers (n = 6/group) underwent sham operation, cranial pole release (CPR), mid-body transection (MBT) or total MX of the medial meniscus. Joints were assessed for gross pathology (cartilage erosion and osteophytes), histomorphometry, two histopathology scoring methods (modified Mankin-type and Pritzker score), and immunohistology for ADAMTS- and MMP-cleaved neoepitopes, at 12 weeks post-op. Ground reaction forces (GRFs) were determined by force plate in a subset (n = 4/group) at baseline, 2.5, 8, and 12 weeks post-op. Gross pathology scores of operated groups differed significantly from sham animals (P osteophyte formation. Similarly, histopathology scores were significantly elevated vs sham but did not differ between operated groups at P subchondral sclerosis, suggesting some residual biomechanical effect from the destabilised but intact meniscus. Few significant differences were noted between operated groups in force plate analyses, though gait abnormalities appeared to be least in CPR sheep, and most persistent (>12 weeks) in MBT animals. The well-validated ovine MX model and the simpler meniscal destabilisation procedures resulted in broadly similar joint pathology and lameness. Meniscal CPR or MBT, as easier and more clinically relevant procedures, may represent preferred models for the induction of OA and evaluation of potential disease-modifying therapies.

    2018-03-01

    Although the teres minor is often overlooked in a normal shoulder, it becomes a key component in maintaining shoulder function when other rotator cuff tendons fail. The teres minor maintains a balanced glenohumeral joint and changes from an insignificant to the most significant external rotator in the presence of major rotator cuff pathology. The presence or absence of the teres minor provides prognostic information on the outcomes of reverse total shoulder arthroplasty and tendon transfers. Clinical tests include the Patte test, the Neer dropping sign, the external rotation lag sign, and the Hertel drop sign. Advanced imaging of the teres minor can be used for classification using the Walch system. Understanding the function and pathology surrounding the teres minor is paramount in comprehensive management of the patient with shoulder pathology. Appropriate clinical examination and imaging of the teres minor are important for preoperative stratification and postoperative expectations.

    Kristopher T. Kimmell, MD

    2014-06-01

    Full Text Available Ectopic pituitary adenomas comprise, by varying reports, approximately 1-2% of all pituitary adenomas. They are often located in the nasopharyngeal region associated with the pharyngeal pituitary. The location and pathologic features of these masses make them atypical when compared with intrasellar pituitary adenomas. A 54-year-old man presented with vertebral compression fracture and physical stigmata of Cushing’s disease. Biochemical testing confirmed hypercortisolemia responsive to high dose dexamethasone suppression. MRI of the head demonstrated an enhancing mass in the posterior aspect of the sphenoid sinus not involving the sella turcica. Endoscopic biopsy followed by resection confirmed this mass to be a pituitary adenoma with unusual pathologic features. Most notably, the tumor cells demonstrated large, eosinophilic, vacuolated cytoplasm. Immunohistochemical profile of the tumor was typical of an ACTH secreting tumor, notably with positivity for ACTH. The patient did well from his surgery. Post-operatively his serum cortisol level normalized and he remains in chemical remission one year after surgery. Ectopic pituitary adenomas are an unusual manifestation of hormonally active pituitary neoplastic disease. Their atypical clinical presentations, location, and pathologic features can make them a diagnostic challenge. Clinicians should be aware of these entities, especially when considering differential diagnosis for a mass in the sphenoid sinus and nasopharyngeal region.

    High-resolution MRI can detect dual pathology (an extrahippocampal lesion plus hippocampal atrophy) in about 5-20% of patients with refractory partial epilepsy referred for surgical evaluation. We report the results of 41 surgical interventions in 38 adults (mean age 31 years, range 14-63 years) with dual pathology. Three patients had two operations. The mean postoperative follow-up was 37 months (range 12-180 months). The extrahippocampal lesions were cortical dysgenesis in 15, tumour in 10, contusion/infarct in eight and vascular malformation in five patients. The surgical approach aimed to remove what was considered to be the most epileptogenic lesion, and the 41 operations were classified into lesionectomy (removal of an extrahippocampal lesion); mesial temporal resection (removal of an atrophic hippocampus); and lesionectomy plus mesial temporal resection (removal of both the lesion and the atrophic hippocampus). Lesionectomy plus mesial temporal resection resulted in complete freedom from seizures in 11/15 (73%) patients, while only 2/10 (20%) patients who had mesial temporal resection alone and 2/16 (12.5%) who had a lesionectomy alone were seizure-free (P dual pathology removal of both the lesion and the atrophic hippocampus is the best surgical approach and should be considered whenever possible.

    We evaluated postoperative outcomes in patients who have lumbar foraminal or extraforaminal disc herniation (FELDH) and suggested the risk factors for poor outcomes. A total of 234 patients were selected for this study. Pre- and post-operative Visual Analogue Scale (VAS) and Korean version Oswestry Disability Index (KODI) were evaluated and the changes of both score were calculated. Outcome was defined as excellent, good, fair, and poor based on Mcnab classification. The percentage of superior facetectomy was calculated by using the Maro-view 5.4 Picture Archiving Communication System (PACS). Paramedian lumbar discectomy was performed in 180 patients and combined lumbar discectomy was performed in 54 patients. Paramedian lumbar discectomy group showed better outcome compared with combined discectomy group. p value of VAS change was 0.009 and KODI was 0.013. The average percentage of superior facetectomy was 33% (range, 0-79%) and it showed negative correlation with VAS and KODI changes (Pearson coefficient : -0.446 and -0.498, respectively). Excellent or good outcome cases (Group I) were 136 (58.1%) and fair or poor outcome cases (Group II) were 98 (41.9%). The percentage of superior facetectomy was 26.5% at Group I and 42.5% at Group II. There was significant difference in superior facetectomy percentage between Group I and II (p=0.000). This study demonstrated that paramedian lumbar discectomy with preservation of facet joints is an effective and good procedure for FELDH. At least 60% of facet should be preserved for excellent or good outcomes.

    A 71-year-old woman was admitted in January 2008 with on upper thoracic esophageal squamous cell carcinoma and a right chest wall skin tumor. When she was 32 years old, she had a radical mastectomy for right breast cancer and received postoperative radiation. Due to the presence of lung adhesions, trans-thoracic esophagectomy could not be done; thus, a blunt dissection was performed. She was discharged on the 19 th postoperative day. On pathology, a pT2N0M0 (pStage II) esophageal tumor was diagnosed. A resection of her skin tumor underwent 79 days after the esophageal surgery; on pathology, the skin tumor was diagnosed as a basal cell carcinoma. Since the esophageal tumor and the skin tumor occurred in the same area that had received radiation therapy, these tumors were diagnosed as being radiation-induced secondary tumors. In the English language medical literature, several reports of radiation-induced esophageal cancer occurring as a second cancer after radiotherapy for breast cancer have been published. Radiation-induced esophageal cancer rates may increase in Japan given the number of women who previously received radiotherapy for breast cancer. (author)

    Patients with pathological stage IA adenocarcinoma (AC) have a variable prognosis, even if treated in the same way. The postoperative treatment of pathological stage IA patients is also controversial. We identified 176 patients with pathological stage IA AC who had undergone a lobectomy and mediastinal lymph node dissection at the Shanghai Chest Hospital, Shanghai, China, between 2000 and 2006. No patient had preoperative treatment. The histologic subtypes of all patients were classified according to the 2011 International Association for the Study of Lung Cancer (IASLC)/American Thoracic Society (ATS)/European Respiratory Society (ERS) international multidisciplinary lung AC classification. Patients' 5-year overall survival (OS) and 5-year disease-free survival (DFS) were calculated using Kaplan-Meier and Cox regression analyses. One hundred seventy-six patients with pathological stage IA AC had an 86.6% 5-year OS and 74.6% 5-year DFS. The 10 patients with micropapillary predominant subtype had the lowest 5-year DFS (40.0%).The 12 patients with solid predominant with mucin production subtype had the lowest 5-year OS (66.7%). Univariate and multivariate analysis showed that sex and prognositic groups of the IASLC/ATS/ERS histologic classification were significantly associated with 5-year DFS of pathological stage IA AC. Our study revealed that sex was an independent prognostic factor of pathological stage IA AC. The IASLC/ATS/ERS classification of lung AC identifies histologic categories with prognostic differences that could be helpful in clinical therapy.

    It is recommended that arteriovenous fistula (AVF) blood flow should be more than 425 ml/min before cannulation. However, the relationship between preoperative radial artery flow (RAF) and postoperative AVF blood flow has still not been examined. Sixty-one patients with end-stage kidney disease (ESKD) were examined. They had an AVF prepared at Juntendo University Hospital from July 2006 through August 2007. Preoperative RAF and postoperative AVF blood flows were measured by ultrasonography. AVF blood flow gradually increased after the operation. AVF blood flow was significantly correlated with preoperative RAF. When preoperative RAF exceeded 21.4 ml/min, AVF blood flow rose to more than 425 ml/min. The postoperative AVF blood flow in the group with RAF of more than 20 ml/min was significantly higher than that in those with less than 20 ml/min. Preoperative RAF of less than 20 ml/min had a significantly high risk of primary AVF failure within 8 months compared with that of more than 20 ml/min. It appears that measurement of RAF by ultrasonography is useful for estimating AVF blood flow postoperatively and can predict the risk of complications in ESKD patients.

    Post-operative ileus (POI) is a common condition after surgery. Failure to restore adequate bowel function after surgery generates a series of complications and it is associated to patients frustration and discomfort, worsening their perioperative experience. Even mild POI can be source of anxiety and could be perceived as a drop out from the "straight-forward" pathway. Enhanced recovery programmes have emphasized the importance of early commencement of oral diet, avoiding the ancient dogmata of prolonged gastric decompression and fasting. These protocols with early oral feeding and mobilization have led to improved perioperative management and have decreased hospital length of stay, ameliorating patient's postoperative experience as well. Nonetheless, the incidence of POI is still high especially after major open abdominal surgery. In order to decrease the incidence of POI, minimally-invasive surgical approaches and minimization of surgical manipulation have been suggested. From a pharmacological perspective, a meta-analysis of pro-kinetics showed beneficial results with alvimopan, although its use has been limited by the augmented risk of myocardial infarction and the high costs. A more simple approach based on the postoperative use of chewing-gum has provided some benefits in restoring bowel function. From an anaesthesiological perspective, epidural anaesthesia/analgesia does not only reduce the postoperative consumption of systemic opioids but directly improve gastrointestinal function and should be considered where possible, at least for open surgical procedures. POI represents a common and debilitating complication that should be challenged with multi-disciplinary approach. Prospective research is warranted on this field and should focus also on patient s reported outcomes.

    Robotic-assisted laparoscopic surgery is an emerging modality in the field of minimally invasive colorectal surgery. However, there is a dearth of data comparing outcomes with other minimally invasive techniques. We present a 3-arm (conventional, hand-assisted, and robotic) matched-case analysis of intraoperative and short-term outcomes in patients undergoing minimally invasive colorectal procedures. Between August 2008 and October 2009, 70 robotic cases of the rectum and rectosigmoid were performed. Thirty of these were organized into triplets with conventional and hand-assisted cases based on the following 6 matching criteria: 1) surgeon; 2) sex; 3) body mass index; 4) operative procedure; 5) pathology; and 6) history of neoadjuvant therapy in malignant cases. Demographics, intraoperative parameters, and postoperative outcomes were assessed. Pathological outcomes were analyzed in malignant cases. Data were stratified by postoperative diagnosis and operative procedure. There was no significant difference in intraoperative complications, estimated blood loss (126.1 ± 98.5 mL overall), or postoperative morbidity and mortality among the groups. Robotic technique required longer operative time compared with conventional laparoscopic (P hand-assisted (P robotic approach results in short-term outcomes comparable to conventional and hand-assisted laparoscopic approaches for benign and malignant diseases of the rectum and rectosigmoid. With 3-dimensional visualization, additional freedom of motion, and improved ergonomics, this enabling technology may play an important role when performing colorectal procedures involving the pelvic anatomy.

    Full Text Available Perioperative infusion of adenosine has been suggested to reduce the requirement for inhalation anesthetics, without causing serious adverse effects in humans. We conducted a meta-analysis of randomized controlled trials evaluating the effect of adenosine on postoperative analgesia.We retrieved articles in computerized searches of Scopus, Web of Science, PubMed, EMBASE, and Cochrane Library databases, up to July 2016. We used adenosine, postoperative analgesia, and postoperative pain(s as key words, with humans, RCT, and CCT as filters. Data of eligible studies were extracted, which included pain scores, cumulative opioid consumption, adverse reactions, and vital signs. Overall incidence rates, relative risk (RR, and 95% confidence intervals (CI were calculated employing fixed-effects or random-effects models, depending on the heterogeneity of the included trials.In total, 757 patients from 9 studies were included. The overall effect of adenosine on postoperative VAS/VRS scores and postoperative opioid consumption was not significantly different from that of controls (P >0.1. The occurrence of PONV and pruritus was not statistically significantly different between an adenosine and nonremifentanil subgroup (P >0.1, but the rate of PONV occurrence was greater in the remifentanil subgroup (P 0.1.Adenosine has no analgesic effect or prophylactic effect against PONV, but reduce systolic blood pressure and heart rates. Adenosine may benefit patients with hypertension, ischemic heart disease, and tachyarrhythmia, thereby improving cardiac function.

    Postoperative delirium (POD) and postoperative cognitive decline (POCD) are common in elderly patients. The aim of the present review was to explore the association of neurodegenerative and neurovascular changes with the occurrence of POD and POCD. Fifteen MRI studies were identified by combining multiple search terms for POD, POCD, and brain imaging. These studies described a total of 1,422 patients and were all observational in design. Neurodegenerative changes (global and regional brain volumes) did not show a consistent association with the occurrence of POD (four studies) or POCD (two studies). In contrast, neurovascular changes (white matter hyperintensities and cerebral infarcts) were more consistently associated with the occurrence of POD (seven studies) and POCD (five studies). In conclusion, neurovascular changes appear to be consistently associated with the occurrence of POD and POCD, and may identify patients at increased risk of these conditions. Larger prospective studies are needed to study the consistency of these findings and to unravel the underlying pathophysiological mechanisms. Copyright © 2017 The Authors. Published by Elsevier Inc.

    Current surgical indications for Graves' disease include intractability to medical and/or radioablative therapy, compressive symptoms, and worsening ophthalmopathy. Total thyroidectomy for Graves' disease may be technically challenging and lead to untoward perioperative outcomes. This study examines outcomes in patients with Graves' disease who underwent total thyroidectomy and assesses its safety for this patient population. A retrospective cross-sectional analysis was performed using the Nationwide Inpatient Sample database from 2006 to 2011. Total thyroidectomy performed in patients with Graves' disease, benign multinodular goiter (MNG), and thyroid cancer was identified. Demographic factors, comorbidities, and postoperative complications were evaluated. Chi-square, one-way analysis of variance, and risk-adjusted multivariable logistic regression were performed. Of 215,068 patients who underwent total thyroidectomy during the study period, 11,205 (5.2%) had Graves' disease, 110,124 (51.2%) MNG, and 93,739 (43.6%) thyroid malignancy. Patients with Graves' disease were younger than MNG and thyroid cancer patients (M age  = 42.8 years vs. 55.5 and 51.0 years; p Graves' disease group included a higher proportion of women (p Graves' disease was independently associated with a higher risk of vocal-cord paralysis (odds ratio [OR] = 1.36 [confidence interval (CI) 1.08-1.69]), tracheostomy (OR = 1.35 [CI 1.1-1.67]), postoperative hypocalcemia (OR = 1.65 [CI 1.54-1.77]), and hematoma requiring reoperation (OR = 2.79 [CI 2.16-3.62]) compared to MNG patients. High-volume centers for total thyroidectomy were independently associated with lower risk of postoperative complications, including in patients with Graves' disease. Despite low overall morbidity following total thyroidectomy, Graves' disease patients are at increased risk of postoperative complications, including bleeding, vocal-cord paralysis, tracheostomy, and hypocalcemia. These risks appear

    Aspirin has been implicated in the postoperative management of moyamoya disease (MMD) in order to avoid bypass failure and decrease the incidence of subsequent stroke. However, its effect has not been completely determined yet. In this study, we retrospectively reviewed data of 184 adult patients (197 hemispheres) presented with ischemic-onset MMD who had undergone direct or combined revascularization in our hospital, to clarify the effect of postoperative aspirin therapy in the management of moyamoya disease. Fifty-nine hemispheres that had been administered with aspirin (100 mg/day) after bypass surgery were defined as the "aspirin group," whereas 138 that hadn't been given aspirin postoperatively were defined as the "control group". Among 197 hemispheres, the mortality rate was 0. The incidence of postoperative newly developed infarction, transient ischemic attack, and hemorrhage were not significantly different between the aspirin and control groups. The patency rate of bypass graft was not significantly different between the groups, either. Notably, more patients experienced major stroke in the control group (9/138) than the aspirin group (1/59), but no statistical difference was found (P > 0.05). In the aspirin group, more patients had improved outcome than the control group (P = 0.04). Our findings showed that aspirin might not decrease the incidence of postoperative ischemic stroke or increase patency rate of bypass graft, but it does not increase the risk of hemorrhages, either. Also, postoperative aspirin therapy might improve outcome. More studies are needed to provide evidence for postoperative antiplatelet therapy in MMD management. Copyright © 2017 Elsevier Inc.

    Full Text Available Elizabeth J Geller Division of Female Pelvic Medicine and Reconstructive Surgery, Department of Obstetrics and Gynecology, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA Abstract: Postoperative urinary retention (POUR is a frequent consequence of gynecologic surgery, especially with surgical correction of urinary incontinence and pelvic organ prolapse. Estimates of retention rates after pelvic surgery range from 2.5%–43%. While there is no standard definition for POUR, it is characterized by impaired bladder emptying, with an elevation in the volume of retained urine. The key to management of POUR is early identification. All patients undergoing pelvic surgery, especially for the correction of incontinence or prolapse, should have an assessment of voiding function prior to discharge. There are several ways to assess voiding function – the gold standard is by measuring a postvoid residual. Management of POUR is fairly straightforward. The goal is to decompress the bladder to avoid long-term damage to bladder integrity and function. The decision regarding when to discontinue catheter-assisted bladder drainage in the postoperative period can be assessed in an ongoing fashion by measurement of postvoid residual. The rate of prolonged POUR beyond 4 weeks is low, and therefore most retention can be expected to resolve spontaneously within 4–6 weeks. When POUR does not resolve spontaneously, more active management may be required. Techniques include urethral dilation, sling stretching, sling incision, partial sling resection, and urethrolysis. While some risk of POUR is inevitable, there are risk factors that are modifiable. Patients that are at higher risk – either due to the procedures being performed or their clinical risk factors – should be counseled regarding the risks and management options for POUR prior to their surgery. Although POUR is a serious condition that can have serious consequences if left untreated, it

    Intravenous thrombolysis (IVT) is beneficial in reducing disability in selected patients with acute ischemic stroke. There are numerous contraindications to IVT. One is recent surgery. The aim of this study was to analyze the safety of IVT in patients with postoperative stroke. Data of consecutive IVT patients from the Telemedical Project for Integrative Stroke Care thrombolysis registry (February 2003 to October 2014; n=4848) were retrospectively searched for keywords indicating preceding surgery. Patients were included if surgery was performed within the last 90 days before stroke. The primary outcome was defined as surgical site hemorrhage. Subgroups with major/minor surgery and recent/nonrecent surgery (within 10 days before IVT) were analyzed separately. One hundred thirty-four patients underwent surgical intervention before IVT. Surgery had been performed recently (days 1-10) in 49 (37%) and nonrecently (days 11-90) in 85 patients (63%). In 86 patients (64%), surgery was classified as major, and in 48 (36%) as minor. Nine patients (7%) developed surgical site hemorrhage after IVT, of whom 4 (3%) were serious, but none was fatal. One fatal bleeding occurred remotely from surgical area. Rate of surgical site hemorrhage was significantly higher in recent than in nonrecent surgery (14.3% versus 2.4%, respectively, odds ratio adjusted 10.73; 95% confidence interval, 1.88-61.27). Difference between patients with major and minor surgeries was less distinct (8.1% and 4.2%, respectively; odds ratio adjusted 4.03; 95% confidence interval, 0.65-25.04). Overall in-hospital mortality was 8.2%. Intracranial hemorrhage occurred in 9.7% and was asymptomatic in all cases. IVT may be administered safely in postoperative patients as off-label use after appropriate risk-benefit assessment. However, bleeding risk in surgical area should be taken into account particularly in patients who have undergone surgery shortly before stroke onset. © 2017 American Heart Association, Inc.

    Full Text Available Background: Pathology informatics is both emerging as a distinct subspecialty and simultaneously becoming deeply integrated within the breadth of pathology practice. As specialists, pathology informaticians need a broad skill set, including aptitude with information fundamentals, information systems, workflow and process, and governance and management. Currently, many of those seeking training in pathology informatics additionally choose training in a second subspecialty. Combining pathology informatics training with molecular pathology is a natural extension, as molecular pathology is a subspecialty with high potential for application of modern biomedical informatics techniques. Methods and Results: Pathology informatics and molecular pathology fellows and faculty evaluated the current fellowship program′s core curriculum topics and subtopics for relevance to molecular pathology. By focusing on the overlap between the two disciplines, a structured curriculum consisting of didactics, operational rotations, and research projects was developed for those fellows interested in both pathology informatics and molecular pathology. Conclusions: The scope of molecular diagnostics is expanding dramatically as technology advances and our understanding of disease extends to the genetic level. Here, we highlight many of the informatics challenges facing molecular pathology today, and outline specific informatics principles necessary for the training of future molecular pathologists.

    to assess the factors associated with the risk of fall in patients undergoing surgical procedures. quantitative and cross-sectional study carried out with 257 adult patients in a hospital in the state of Minas Gerais, Brazil. Data were collected using the sociodemographic and clinical questionnaire, the Morse Fall Scale, and the Quality of Recovery Score. Data were submitted to descriptive statistical analysis and multinomial logistic regression. The level of significance was set at 0.05. 35.4% of patients had high risk of falls, 38.9% had moderate risk and 25.7% had low risk. The mean value in the surgical recovery scale was 175.37 points and no patient presented poor surgical recovery. Regarding the results of the bivariate analysis, it was found that age (prisk of fall, whereas cancer (p=0.004) was positively associated with moderate risk of fall. Surgical recovery (p=0,008) was inversely associated with high risk of fall. the results of this study allowed the identification of five factors associated with the risk of fall in adults in the postoperative hospital stay. These findings may support the planning of nursing actions aimed at preventing the risk of fall in the postoperative period. evaluar los factores asociados al riesgo de caída en pacientes sometidos a procedimientos quirúrgicos. estudio cuantitativo, transversal, realizado en 257 pacientes adultos en un hospital de Minas Gerais, Brasil.

    The US medical malpractice system assumes that the threat of liability should deter negligence, but it is unclear whether malpractice environment affects health care quality. We sought to explore the association between state malpractice environment and postoperative complication rates. This observational study included Medicare fee-for-service beneficiaries undergoing one of the following operations in 2010: colorectal, lung, esophageal, or pancreatic resection, total knee arthroplasty, craniotomy, gastric bypass, abdominal aortic aneurysm repair, coronary artery bypass grafting, or cystectomy. The state-specific malpractice environment was measured by 2010 medical malpractice insurance premiums, state average award size, paid malpractice claims/100 physicians, and a composite malpractice measure. Outcomes of interest included 30-day readmission, mortality, and postoperative complications (eg sepsis, myocardial infarction [MI], pneumonia). Using Medicare administrative claims data, associations between malpractice environment and postoperative outcomes were estimated using hierarchical logistic regression models with hospital random-intercepts. Measures of malpractice environment did not have significant, consistent associations with postoperative outcomes. No individual tort reform law was consistently associated with improved postoperative outcomes. Higher-risk state malpractice environment, based on the composite measure, was associated with higher likelihood of sepsis (odds ratio [OR] 1.22; 95% CI 1.07 to 1.39), MI (OR 1.14; 95% CI 1.06 to 1.23), pneumonia (OR 1.09; 95% CI 1.03 to 1.16), acute renal failure (OR 1.15; 95% CI 1.08 to 1.22), deep vein thrombosis/pulmonary embolism (OR 1.22; 95% CI 1.13 to 1.32), and gastrointestinal bleed (OR 1.18; 95% CI 1.08 to 1.30). Higher risk malpractice environments were not consistently associated with a lower likelihood of surgical postoperative complications, bringing into question the ability of malpractice lawsuits to

    Modern neuroimaging can disclose epileptogenic lesions in many patients with partial epilepsy and, at times, display the coexistence of hippocampal atrophy in addition to an extrahippocampal lesion (dual pathology). We studied the postoperative seizure outcome of 64 patients with lesional epilepsy (median follow-up, 30 months) and considered separately the surgical results in the 51 patients with a single lesion and in the 13 who had dual pathology. In patients with a single lesion, 85% were seizure free or significantly improved (Engel's class I-II) when the lesion was totally removed compared with only 40% when there was incomplete resection (p dual pathology who had both the lesion and the atrophic hippocampus removed became seizure free. In contrast, only 2 of the 10 patients with dual pathology undergoing surgery aimed at the lesion or at the hippocampus alone became seizure free (p dual pathology, surgery should, if possible, include resection of both the lesion and the atrophic hippocampus.

    To determine the prevalence of photographic signs of nondiabetic retinal pathology in Australian general practice patients with diabetes. Three hundred and seven patients with diabetes underwent retinal photography at two general practices, one of which was an indigenous health centre. The images were assessed for signs of pathology by an ophthalmologist. Signs of nondiabetic retinal pathology were detected in 31% of subjects with adequate photographs. Features suspicious of glaucoma were detected in 7.7% of subjects. Other abnormalities detected included signs of age related macular degeneration (1.9%), epiretinal membranes (2.4%), vascular pathology (9.6%), chorioretinal lesions (2.9%), and congenital disc anomalies (2.9%). Indigenous Australian patients were more likely to have signs of retinal pathology and glaucoma. Signs of nondiabetic retinal pathology were frequently encountered. In high risk groups, general practice based diabetic retinopathy screening may reduce the incidence of preventable visual impairment, beyond the benefits of detection of diabetic retinopathy alone.

    To determine the incidence of vitreoretinal pathologic conditions in myopic eyes after laser in situ keratomileusis. Vitreoretinal pathologic conditions of 1981 consecutive eyes (995 patients) having undergone laser-assisted in situ keratomileusis for the correction of myopia were studied. Preoperative and postoperative basic examinations included visual acuity, manifest and cycloplegic refraction, slit-lamp microscope examination, applanation tonometry and a fundus examination after pupil dilatation by indirect ophthalmoscopy and biomicroscopy with spherical lens of + 90 diopters. Before laser in situ keratomileusis, preventive treatment was carried out for predisposing lesion of retinal detachment in 8 eyes: 6 eyes for lattice degeneration and 2 eyes for atrophic holes.

    Full Text Available BACKGROUND To provide postoperative pain relief is a prime duty of health care providers. Failure to relieve pain is morally and ethically unacceptable. Post-operative pain may results in adverse effects such as: a Physiological Changes: Reduced pulmonary functions, e.g. vital capacity, tidal volume, functional residual capacity; sympathetic stimulation; reduced the physical activity of patients; thereby increasing the risk of venous thrombosis. b Psychological disturbances: Anger, Resentment, Depression, Adversarial Relationship with Doctors, Insomnia. Aim of this study was 1. To investigate whether “Postoperative analgesia with Nalbuphine is longer than Pentazocine”. 2. To investigate whether “Side effects/complications are less with Nalbuphine as compared to Pentazocine”. MATERIALS AND METHODS It was a prospective randomized double blind observational study. Eighty patients of hydrocoele & inguinal hernia were operated under spinal anaesthesia of age group 20-70 years, ASA grade I & II & patients with controlled co-morbid conditions. In postoperative period, Group N- Inj. Nalbuphine (0.3 mg/kg IM or Group P- Inj. Pentazocine (0.5 mg/kg IM was administered to provide postoperative pain relief & to know the duration of pain relief & its side effects. RESULTS On statistical analysis, demographic data i.e. age, sex had no influence on outcome of study. Mean VAS score in group N was highly significant (p-value in Inj. Pentazocine group. 2. Side Effects - Incidence of sedation was more in Nalbuphine group as compared to Pentazocine group. Nausea & Vomiting were more so in Pentazocine group as compared to Nalbuphine group. Limitation of the present study was that sample size was very small.

    Esophageal achalasia is a relatively rare disease that occurs usually in middle-aged patients. The laparoscopic Heller-Dor (LHD) procedure is the gold-standard surgical treatment for esophageal achalasia. There are many studies on the pathology and surgical outcome of esophageal achalasia from various perspectives, but there are no studies on gender differences in both the pathology and surgical outcome. This study aimed to evaluate gender differences in the surgical outcome with the LHD procedure and in the pathology of esophageal achalasia patients. The study included 474 LHD-treated patients who were postoperatively followed up for 6 months or more. The patients were divided into 2 groups by gender, to compare the preoperative pathology, surgical outcome, symptom scores before and after LHD, symptom score improvement frequency, and patient satisfaction with the surgery. The study population consisted of 248 male and 226 female, having a mean age of 45.1 years. There were no gender differences in the preoperative pathology, but a significantly lower BMI (p achalasia were characterized by low BMI, less esophageal dilation, and increased frequency and severity of chest pain. LHD improved the chest pain in the female patients, whereas the surgical outcome and satisfaction with the surgery were excellent regardless of gender.

  20. Nursing Music Protocol and Postoperative Pain.

    Pain has always been a major concern for patients and nurses during the postoperative period. Therapies, medicines, and protocols have been developed to improve pain and anxiety but have undesirable risks to the patient. Complementary and alternative medicine therapies have been studied but have not been applied as regular protocols in the hospital setting. Music is one type of complementary and alternative medicine therapy that has been reported to have favorable results on reducing postoperative pain, anxiety, and opioid usage. However, music lacks a protocol that nurses can implement during the perioperative process. This paper is an in-depth literature review assessing a best practice recommendation and protocol that establishes a consensus in the use of music therapy. The results suggest that music therapy may consist of calming, soft tones of 60-80 beats per minute for at least 15-30 minutes at least twice daily during the pre- and postoperative periods. It is suggested that music only be used in conjunction with standards of care and not as the primary intervention of pain or anxiety. This evidence suggests that proper use of music therapy can significantly reduce surgical pain. Implementing these protocols and allowing the freedom of nursing staff to use them may lead to greater reductions in surgical pain and anxiety and a reduction in opioid use.

    The current standard of care for post-operative high-risk squamous cell carcinoma of the head and neck is concurrent chemoradiotherapy with a 3-weekly cycle of cisplatin (3W-CDDP/RT). In previous pivotal trials, the complete delivery rate of three cycles of cisplatin and radiation therapy was only -60%. Here, we evaluated the feasibility and safety of 3W-CDDP/RT in a Japanese population. The study enrolled post-operative high-risk squamous cell carcinoma of the head and neck patients. High-risk factors were a microscopically incomplete resection, extracapsular extension and two or more lymph node metastases. Subjects received three cycles of cisplatin at a dose of 100 mg/m 2 concomitant with radiation therapy (66 Gy/33 Fr). From August 2006 to May 2009, 25 eligible subjects were accrued, including 13 males, with a median age of 59 years, Eastern Cooperative Oncology Group performance status 0/1 (18/7), Stage III/IVA/IVB/recurrent (1/18/1/5) and oral cavity/oropharynx/hypopharynx/larynx (17/4/3/1). Protocol completion rate was 80%. The lower limit of the one-sided 90% confidence interval was 66%, which met the predefined statistical criteria. Grade 3/4 acute and late toxicities were almost identical to those in previous pivotal trials. No treatment-related deaths were observed. With a median follow-up of 39 months, 14 have had progression and 10 have died. Estimated 3-year locoregional control rate, relapse-free survival and overall survival were 74, 43 and 60%, respectively. On univariate analysis, oral cavity cancer and a cumulative cisplatin dose below 240 mg/m 2 appeared to be poor prognostic factors. This is the first Phase II feasibility trial of adjuvant chemoradiotherapy with 3-weekly cisplatin for post-operative high-risk squamous cell carcinoma of the head and neck in a Japanese population. This treatment was feasible and the safety profile was identical to those in pivotal Phase III trials. (author)

    Background: The purpose of this work was to determine efficacy, toxicity, and patterns of recurrence after concurrent chemoradiation (CRT) in patients with extrahepatic bile duct cancer (EHBDC) and hilar cholangiocarcinoma (Klatskin tumours) in case of incomplete resection or unresectable disease. Patients and methods: From 2003-2010, 25 patients with nonmetastasized EHBDC and hilar cholangiocarcinoma were treated with radiotherapy and CRT at our institution in an postoperative setting (10 patients, 9 patients with R1 resections) or in case of unresectable disease (15 patients). Median age was 63 years (range 38-80 years) and there were 20 men and 5 women. Median applied dose was 45 Gy in both patient groups. Results: Patients at high risk (9 times R1 resection, 1 pathologically confirmed lymphangiosis) for tumour recurrence after curative surgery had a median time to disease progression of 8.7 months and an estimated mean overall survival of 23.2 months (6 of 10 patients are still under observation). Patients undergoing combined chemoradiation in case of unresectable primary tumours are still having a poor prognosis with a progression-free survival of 7.1 months and a median overall survival of 12.0 months. The main site of progression was systemic (liver, peritoneum) in both patient groups. Conclusion: Chemoradiation with gemcitabine is safe and can be applied safely in either patients with EHBDC or Klatskin tumours at high risk for tumour recurrence after resection and patients with unresectable tumours. Escalation of systemic and local treatment should be investigated in future clinical trials. (orig.)

    BACKGROUND Accurate preoperative and postoperative risk assessment has been critical for counseling patients regarding radical prostatectomy for clinically localized prostate cancer. In addition to other treatment modalities, neoadjuvant or adjuvant therapies have been considered. The growing literature suggested that the experience of the surgeon may affect the risk of prostate cancer recurrence. The purpose of this study was to develop and internally validate nomograms to predict the probability of recurrence, both preoperatively and postoperatively, with adjustment for standard parameters plus surgeon experience. METHODS The study cohort included 7724 eligible prostate cancer patients treated with radical prostatectomy by 1 of 72 surgeons. For each patient, surgeon experience was coded as the total number of cases conducted by the surgeon before the patient’s operation. Multivariable Cox proportional hazards regression models were developed to predict recurrence. Discrimination and calibration of the models was assessed following bootstrapping methods, and the models were presented as nomograms. RESULTS In this combined series, the 10-year probability of recurrence was 23.9%. The nomograms were quite discriminating (preoperative concordance index, 0.767; postoperative concordance index, 0.812). Calibration appeared to be very good for each. Surgeon experience seemed to have a quite modest effect, especially postoperatively. CONCLUSIONS Nomograms have been developed that consider the surgeon’s experience as a predictor. The tools appeared to predict reasonably well but were somewhat little improved with the addition of surgeon experience as a predictor variable. PMID:19156928

    The management of asymptomatic patients with mitral regurgitation (MR) remains controversial. Exercise-induced pulmonary hypertension (ExPHT) was recently reported as a strong predictor of rapid onset of symptoms. We hypothesised that ExPHT is a predictor of postoperative cardiovascular events in patients with primary MR. One hundred and two patients with primary MR, no or mild symptoms (New York heart association (NYHA) ≤2), and no LV dysfunction/dilatation, were prospectively recruited in 3 centres and underwent exercise-stress echocardiography. The presence of ExPHT was defined as an exercise systolic pulmonary arterial pressure >60 mm Hg. All patients were closely followed up and operated on when indication for surgery was reached. Postoperative events were defined as the occurrence of atrial fibrillation (AF), stroke, cardiac-related hospitalisation or death. Among the 102 patients included, 59 developed ExPHT (58%). These patients were significantly older than those without ExPHT (p=0.01). During a mean postoperative follow-up of 50±23 months, 28 patients (26%) experienced a predefined cardiovascular event. Patients with ExPHT had significantly higher rate of postoperative events (39% vs 12%, p=0.005); the rate of events was still higher in these patients (32% vs 9%, p=0.013), even when excluding early postoperative AF (ie, within 48 h). Event-free survival was significantly lower in the ExPHT group (all events: 5-year: 60±8% vs 88±5%, p=0.007, events without early AF: 5-year: 67±7% vs 90±4%, p=0.02). Using Cox multivariable analysis, ExPHT remained independently associated with higher risk of postoperative events in all models (all p≤0.04). ExPHT is associated with increased risk of adverse cardiac events following mitral valve surgery in patients with primary MR. Published by the BMJ Publishing Group Limited.

  6. Postoperative Ileus in the Elderly

    2014-03-01

    Full Text Available Postoperative ileus is among the most common complications after surgery. Aging is associated with an increased colonic transit time, and anesthetic disturbance to colonic motility is often aggravated in the elderly. Postoperative ileus increases morbidity, prolongs the length of hospital stay, and constitutes a significant economic burden on the healthcare system. Multimodal enhanced recovery protocols, or fast-track surgeries, have been developed to improve postoperative recovery. Patient education, avoidance of perioperative fluid overload, selective use of nasogastric decompression, early ambulation, adopting a minimally invasive approach, early initiation of clear fluids, and gum chewing are all possible measures to reduce postoperative ileus. Thoracic epidural anesthesia is a well-established technique to hasten recovery, whereas insufficient data are available to ascertain the safety and efficacy of opioid-sparing analgesia in the elderly. The evidence is clear that traditional prokinetic medications are not helpful in the treatment or prevention of postoperative ileus. Early results suggest that alvimopan is a promising agent to reverse opioid-induced ileus. Since postoperative ileus is a multifactorial condition, a concerted effort is therefore necessary to prevent or decrease the duration of postoperative ileus using multimodal strategies.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

    2010-01-01

    Purpose: The goal of this study was to determine the role of radiotherapy after curative-intent surgery in the management of extrahepatic bile duct (EHBD) cancers. Methods and Materials: From 1997 through 2005, 78 patients with EHBD cancer were surgically staged. These patients were stratified by the absence of adjuvant radiation (n = 47, group I) versus radiation (n = 31, group II) after resection. Pathology examination showed 27 cases in group I and 20 cases in group II had microscopically positive resection margins. The patients in group II received 45 to 54 Gy of external beam radiotherapy. The primary endpoints of this study were overall survival, disease-free survival, and prognostic factors. Results: There were no differences between the 5-year overall survival rates for the two groups (11.6% in group I vs. 21% in group II). However, the patients with microscopically positive resection margins who received adjuvant radiation therapy had higher median disease-free survival rates than those who underwent surgery alone (21 months vs. 10 months, respectively, p = 0.042). Decreasing local failure was found in patients who received postoperative radiotherapy (61.7% in group I and 35.6% in group II, p = 0.02). Outcomes of the patients with a positive resection margin and lymph node metastasis who received postoperative radiation therapy were doubled compared to those of patients without adjuvant radiotherapy. Resection margin status, lymph node metastasis, and pathology differentiation were significant prognostic factors in disease-free survival. Conclusions: Adjuvant radiotherapy might be useful in patients with EHBD cancer, especially for those patients with microscopic residual tumors and positive lymph nodes after resection for increasing local control.

    Racial disparities in the incidence and risk profile of prostate cancer at diagnosis among African-American men are well reported. However, it remains unclear whether African-American race is independently associated with adverse outcomes in men with clinical low risk disease. We retrospectively analyzed the records of 895 men in the SEARCH (Shared Equal Access Regional Cancer Hospital) database in whom clinical low risk prostate cancer was treated with radical prostatectomy. Associations of African-American and Caucasian race with pathological biochemical recurrence outcomes were examined using chi-square, logistic regression, log rank and Cox proportional hazards analyses. We identified 355 African-American and 540 Caucasian men with low risk tumors in the SEARCH cohort who were followed a median of 6.3 years. Following adjustment for relevant covariates African-American race was not significantly associated with pathological upgrading (OR 1.33, p = 0.12), major upgrading (OR 0.58, p = 0.10), up-staging (OR 1.09, p = 0.73) or positive surgical margins (OR 1.04, p = 0.81). Five-year recurrence-free survival rates were 73.4% in African-American men and 78.4% in Caucasian men (log rank p = 0.18). In a Cox proportional hazards analysis model African-American race was not significantly associated with biochemical recurrence (HR 1.11, p = 0.52). In a cohort of patients at clinical low risk who were treated with prostatectomy in an equal access health system with a high representation of African-American men we observed no significant differences in the rates of pathological upgrading, up-staging or biochemical recurrence. These data support continued use of active surveillance in African-American men. Upgrading and up-staging remain concerning possibilities for all men regardless of race.

    Full Text Available Abstract Background Postoperative pancreas fistula (POPF is a major complication after total gastrectomy with splenectomy. We retrospectively studied the effects of upper abdominal shape on the development of POPF after gastrectomy. Methods Fifty patients who underwent total gastrectomy with splenectomy were studied. The maximum vertical distance measured by computed tomography (CT between the anterior abdominal skin and the back skin (U-APD and the maximum horizontal distance of a plane at a right angle to U-APD (U-TD were measured at the umbilicus. The distance between the anterior abdominal skin and the root of the celiac artery (CAD and the distance of a horizontal plane at a right angle to CAD (CATD were measured at the root of the celiac artery. The CA depth ratio (CAD/CATD was calculated. Results POPF occurred in 7 patients (14.0% and was associated with a higher BMI, longer CAD, and higher CA depth ratio. However, CATD, U-APD, and U-TD did not differ significantly between patients with and those without POPF. Logistic-regression analysis revealed that a high BMI (≥25 and a high CA depth ratio (≥0.370 independently predicted the occurrence of POPF (odds ratio = 19.007, p = 0.002; odds ratio = 13.656, p = 0.038, respectively. Conclusion Surgical procedures such as total gastrectomy with splenectomy should be very carefully executed in obese patients or patients with a deep abdominal cavity to decrease the risk of postoperative pancreatic fistula. BMI and body shape can predict the risk of POPF simply by CT.

    Delirium is a common complication in postoperative, critically ill patients. The mechanism of postoperative delirium is not well understood but many studies have shown significant associations between benzodiazepine use, alcohol withdrawal and cirrhosis, and an increased risk of delirium. We aimed to investigate a possible link with alterations of gamma-aminobutyric acid (GABA) activity. A prospective observational investigation of 40 patients > 20 years old who had undergone elective surgery with general anaesthesia and were expected to need postoperative intensive care for more than 48 hours. We assessed postoperative delirium using the confusion assessment method in the intensive care unit at 1 hour after the operation and on postoperative Day (POD) 1 and POD 2. We collected blood samples for measurement of plasma GABA concentrations before the operation and on POD 1 and 2. Postoperative delirium and perioperative plasma GABA concentrations in patients with and without delirium. Postoperative delirium occurred in 13 of the patients. Patients with delirium had significantly higher Acute Physiology and Chronic Health Evaluation II scores than patients without delirium. The mean plasma GABA concentration on POD 2 was significantly lower in patients with delirium than in those without delirium. After adjustment of relevant variables, plasma GABA concentration on POD 2 was independently associated with postoperative delirium. Plasma GABA level on POD 2 has a significant independent association with postoperative delirium.

    This paper reports on the importance of postoperative radiology. Most surgical procedures on the alimentary tract are successful, but postoperative complications remain a common occurrence. The radiologist must be familiar with a large variety of possible surgical complications, because it is this specialty that is most commonly called on to render a definitive diagnosis. The decision for reoperation, for instance, is usually based on results from radiologic imaging techniques.

    Context We define the scope and needs within the new discipline of computational pathology, a discipline critical to the future of both the practice of pathology and, more broadly, medical practice in general. Objective To define the scope and needs of computational pathology. Data Sources A meeting was convened in Boston, Massachusetts, in July 2014 prior to the annual Association of Pathology Chairs meeting, and it was attended by a variety of pathologists, including individuals highly invested in pathology informatics as well as chairs of pathology departments. Conclusions The meeting made recommendations to promote computational pathology, including clearly defining the field and articulating its value propositions; asserting that the value propositions for health care systems must include means to incorporate robust computational approaches to implement data-driven methods that aid in guiding individual and population health care; leveraging computational pathology as a center for data interpretation in modern health care systems; stating that realizing the value proposition will require working with institutional administrations, other departments, and pathology colleagues; declaring that a robust pipeline should be fostered that trains and develops future computational pathologists, for those with both pathology and non-pathology backgrounds; and deciding that computational pathology should serve as a hub for data-related research in health care systems. The dissemination of these recommendations to pathology and bioinformatics departments should help facilitate the development of computational pathology. PMID:26098131

    Recent work has revealed a relationship between pathological video game use and increased impulsivity among children and adolescents. A few studies have also demonstrated increased risk-taking outside of the video game environment following game play, but this work has largely focused on one genre of video games (i.e., racing). Motivated by these findings, the aim of the current study was to examine the relationship between pathological and non-pathological video game use, impulsivity, and risky decision making. The current study also investigated the relationship between experience with two of the most popular genres of video games [i.e., first-person shooter (FPS) and strategy] and risky decision making. Consistent with previous work, ~7% of the current sample of college-aged adults met criteria for pathological video game use. The number of hours spent gaming per week was associated with increased impulsivity on a self-report measure and on the temporal discounting (TD) task. This relationship was sensitive to the genre of video game; specifically, experience with FPS games was positively correlated with impulsivity, while experience with strategy games was negatively correlated with impulsivity. Hours per week and pathological symptoms predicted greater risk-taking in the risk task and the Iowa Gambling task, accompanied by worse overall performance, indicating that even when risky choices did not pay off, individuals who spent more time gaming and endorsed more symptoms of pathological gaming continued to make these choices. Based on these data, we suggest that the presence of pathological symptoms and the genre of video game (e.g., FPS, strategy) may be important factors in determining how the amount of game experience relates to impulsivity and risky-decision making.

    Purpose: To analyze retrospectively the outcome of postoperative radiation therapy with or without concurrent chemotherapy for curatively resected stage II pancreatic cancer with T3 or N1 disease. Materials and Methods: Between January 1996 and December 2005, twenty-eight patients completed adjuvant radiation therapy at Ajou University Hospital. The patients had either pathologic T3 stage or N1 stage. The radiation target volume encompassed the initial tumor bed identified preoperatively, resection margin area and celiac nodal area. In the case of N1 patients, the radiation field extended to the lower margin of the L3 vertebra for covering both para-aortic lymph nodes bearing area. The median total radiation dose was 50 Gy. Ten patients received concurrent chemotherapy. Results: Thirteen patients (46%) showed loco-regional recurrences. The celiac axis nodal area was the most frequent site (4 patients). Five patients showed both loco-regional recurrence and a distant metastasis. Patients with positive lymph nodes had a relatively high probability of a distant metastasis (57.1%). Patients that had a positive resection margin showed a relatively high local failure rate (57.1%). The median disease-free survival period of all patients was 6 months and the 1- and 2-year disease free survival rates were 27.4% and 8.2%, respectively. The median overall survival period was 9 months. The 2- and 3-year overall survival rates were 31.6% and 15.8%, respectively. Conclusion: The pancreatic cancer patients with stage II had a high risk of local failure and a high risk of a distant metastasis. We suggest the concurrent use of an effective radiation-sensitizing chemotherapeutic drug and adjuvant chemotherapy after postoperative radiation therapy for the treatment of patients with stage II pancreatic cancer.

    This study sought to extend extant research on the association between borderline personality (BP) pathology and at-risk parenting by examining the dynamic nature of parenting in response to infant distress in mothers with and without clinically relevant levels of BP pathology. Findings revealed that mothers with clinically relevant levels of BP pathology were less likely than those without BP pathology to display positive affect in response to infant distress. There were no differences in the overall likelihood of insensitive parenting behaviors as a function of BP pathology, either in general or in response to infant distress. However, consistent with literature emphasizing the transactional nature of parent-child relationships, findings revealed that the likelihood of insensitive parenting behaviors among mothers with clinically relevant levels of BP pathology changed over time, increasing significantly as infant distress persisted for longer durations (a pattern not present for mothers without BP pathology). Moreover, maternal responses to infant distress were found to influence infant distress, with the likelihood of infant distress decreasing after maternal positive affect and increasing after maternal insensitive behaviors. The implications of findings for understanding the mechanisms of risk for children of mothers with BP pathology, as well as the transactional nature of mother-infant relationships in general, are discussed.

    Full Text Available Background: We developed a multi-dimensional score which may help in predicting those patients, undergoing bariatric surgery, who may be in need for postoperative ICU admission and which may also help in avoiding unnecessary admission to the critical care units after bariatric surgery. Methods: We collected the data of 111patients who underwent either laparoscopic gastric sleeve or bypass and studied the association between some risk factors related to obesity and their postoperative ICU admission. Those factors found to be statistically significant are included in the final score. The cutoff value of our scoring system is determined by running a Receiver Operating Curve (ROC analysis. Results: Forty patients (36% were admitted to the ICU postoperatively. Our final score includes 7 independent variables; 6 found to be significantly related to post-bariatric surgery ICU admission; these are age, gender, BMI, ASA, obstructive sleep apnea and spirometry results, and the seventh is the history of venous thrombo-embolism. According to the ROC curve analysis, we set the score value of 10 as our cut-off value for the need of postoperative ICU admission. The score median value is 9. Males’ odds to be admitted to the ICU after bariatric surgery are 11.9 times higher than females. Also, those with BMI above 50 kg m−2 have odds of 29.8 times higher than those below 50 kg m−2. Conclusions: We propose a scoring system for risk stratification, in which some of the well-known predictor risk factors are included in a simple way to help identify those high-risk patients undergoing bariatric surgery.Trial registry number: NCT02976649.

    Formation of heterotopic bone (HTB) following total hip replacement may partially or completely ankylose the joint space, causing pain and/or limiting the range of motion. Patients at high risk for formation of HTB postoperatively include those with previous HTB formation, heterotopic osteoarthritis, and active rheumatoid spondylitis. Patients in these high risk groups have a 63-69% incidence of post-operative HTB formation, usually seen radiographically by 2 months post-operation. From 1980-1986 twenty-nine hips in 28 consecutively treated patients were irradiated post-operatively at the UCLA Center for the Health Sciences. The indication for irradiation was documented HTB formation previously in 26 of the 27 hips presented below. From 1980-1982 patients received 20 Gray (Gy) in 2 Gy fractions; from 1982-1986 the dose was reduced to 10 Gy in 2 Gy fractions. Twenty-seven hips in 26 patients completed therapy and were available for evaluation, with a minimum of 2 month follow-up, and a median follow-up of 12 months. Three of 27 hips developed significant HTB (Brooker grade III or IV) post-operatively, whereas 5 of 27 hips developed minor, nonsymptomatic HTB (Brooker grade I). When irradiation was begun by postoperative day 4, 0 of 17 hips formed significant HTB. If irradiation began after post-operative day 4, 3 of 10 hips formed significant HTB (Brooker grade III or IV). These 3 hips received doses of 10 Gy in one hip and 20 Gy in the other 2 hips. There were no differences in the incidence or severity of side effects in the 10 Gy vs. the 20 Gy treatment groups. Eighteen hips received 10 Gy, 8 hips 20 Gy and, 1 hip 12 Gy. In conclusion, 10 Gy in 5 fractions appears as effective as 20 Gy in 10 fractions at preventing post-operative formation of HTB. For optimal results, treatment should begin as early as possible prior to post-operative day 4

    Full Text Available Postoperative nausea and vomiting (PONV are still a significant problem in modern anesthetic practice. Discomfort caused by PONV intensifies other unpleasant elements of recovery, such as pain, frustration or fear. PONV also generates aversion to future anesthesia and have a negative impact on staff and patient's family. PONV can increase the cost of completing a surgical procedure, because it extends the time a patient spends in the postanesthesia care unit (PACU or delay discharge of ambulatory patients. It is generally accepted that the incidence of PONV after general anesthesia for various types of surgery in the last decade is still between 20-30%, and 70% in laparoscopic abdominal surgery. The incidence is three times higher in females compared to males. Many factors are involved in triggering PONV, such as patientrelated factors, the type of surgery, anesthesia management, etc. The results of this study suggest that the patient positioning (modified supine lithotomy position with ''Trendelenburg" increases the risk of PONV in gynecologic laparoscopy.

    There are limited treatment options beyond surgical salvage for patients who fail nonoperative treatment for laryngeal squamous cell carcinoma. In this study, we examine the failure patterns after surgical salvage and the potential pathologic and clinical prognostic variables that might guide further postoperative intensification investigation. Retrospective analysis at a tertiary academic referral center. From an institutional review board-approved institutional head and neck cancer registry, a consecutive series of 147 patients who underwent salvage laryngectomy for squamous cell cancer recurrence or persistence after radiotherapy with or without chemotherapy between May 1995 and May 2016 were identified. Variables potentially associated with oncologic outcome after surgical salvage were then collected and retrospectively evaluated. The projected 2-year locoregional failure rate was 21.8% (95% confidence interval [CI], 14.6%-29.0%]), and the overall survival 65% (95% CI, 57.5%-74.3%) for the entire cohort after salvage laryngectomy. On multivariable analysis, sarcomatoid/spindle cell pathology (hazard ratio [HR], 3.147; 95% CI, 1.181-8.386; P = 0.022), lymphovascular space invasion (LVSI) (positive vs. negative; HR, 2.31; 95% CI, 1.21-4.42; P = 0.011), and advanced initial American Joint Committee on Cancer 7th Edition grouped stage (stages III-IVB vs. stages I-II; HR, 1.64; 95% CI, 1.04-2.6; P = 0.035) were found to be independently associated with inferior disease-free survival. No other clinical or pathologic variables predicted failure. Salvage laryngectomy after nonoperative treatment failure results in successful locoregional control rates and survival in the majority of patients failing initial therapy. This should temper enthusiasm for routine treatment intensification with postoperative re-irradiation and/or other systemic treatments for the vast majority of patients. Sarcomatoid pathology, LVSI, and an advanced initial stage are associated with inferior

    To evaluate concordance (C) between pre-operative hysteroscopic-directed sampling and final pathology in uterine cancers. A retrospective cross-sectional evaluation of prospectively collected data of women who underwent hysterectomy for uterine malignancies and a previous hysteroscopic-guided biopsy was performed. Diagnostic concordance between pre-operative (hysteroscopic biopsy) and postoperative (uterine specimen) histology was evaluated. In endometrioid-endometrial cancers cases Kappa (k) statistics was applied to evaluate agreement for grading (G) between the preoperative and final pathology. A total 101 hysterectomies for uterine malignancies were evaluated. There were 23 non-endometrioid cancers: 7 serous (C:5/7, 71.4%); 10 carcinosarcomas (C:7/10, 70%, remaining 3 cases only epithelial component diagnosed); 3 clear cell (C:3/3, 100%); 3 sarcomas (C:3/3, 100%). In 78 cases an endometrioid endometrial cancer was found. In 63 cases there was a histological C (63/78, 80.8%) between hysteroscopic-guided biopsy and final pathology, while in 15 cases (19.2%) only hyperplasia (with/without atypia) was found preoperatively. Overall accuracy to detect endometrial cancer was 80.2%. In 50 out of 63 endometrial cancers (79.4%) grading was concordant. The overall level of agreement between preoperative and postoperative grading was "substantial" according to Kappa (k) statistics (k 0.64; 95% CI: 0.449-0.83; p < 0.001), as well as for G1 (0.679; 95% CI: 0.432-0.926; p < 0.001) and G3 (0.774; 94% CI: 0.534-1; p < 0.001), while for G2 (0.531; 95% CI: 0.286-0.777; p < 0.001) it was moderate. In our series we found an 80% C between pre-operative hysteroscopic-guided biopsy and final pathology, in uterine malignancies. Moreover, hysteroscopic biopsy accurately predicted endometrial cancer in 80% of cases and "substantially" predicted histological grading. Hysteroscopic-guided uterine sampling could be a useful tool to tailor treatment in patients with uterine

    Milrinone reduces the risk of low cardiac output syndrome for some pediatric patients after congenital heart surgery. Data from adults undergoing cardiac surgery suggest an association between milrinone and an increased risk of postoperative arrhythmias. We tested the hypothesis that milrinone is an independent risk factor for tachyarrhythmias after congenital heart surgery. Subjects undergoing congenital heart surgery at our institution were consecutively enrolled for 38 months, through September 2010. The data were prospectively collected, including a review of full-disclosure telemetry and the medical records. Within 38 months, 603 enrolled subjects underwent 724 operative procedures. The median age was 5.5 months (range 0.0 to 426), the median weight was 6.0 kg (range 0.7 to 108), and the cohort was 45% female. The overall arrhythmia incidence was 50%, most commonly monomorphic ventricular tachycardia (n = 85, 12%), junctional ectopic tachycardia (n = 69, 10%), accelerated junctional rhythm (n = 58, 8%), and atrial tachyarrhythmias (including atrial fibrillation, atrial flutter, and ectopic or chaotic atrial tachycardia, n = 58, 8%). Multivariate logistic regression analysis demonstrated that independent of age 3, and the use of epinephrine or dopamine, milrinone use on admission to the cardiac intensive care unit remained independently associated with an increase in the odds of postoperative tachyarrhythmia resulting in an intervention (odds ratio 2.8, 95% confidence interval 1.3 to 6.0, p = 0.007). In conclusion, milrinone use is an independent risk factor for clinically significant tachyarrhythmias in the early postoperative period after congenital heart surgery. Copyright © 2011 Elsevier Inc.

Multivariate logistic regression analysis demonstrated that independent of age less than 1 month, use of cardiopulmonary bypass, duration of cardiopulmonary bypass, RACHS-1 score greater than 3, and the use of epinephrine or dopamine, milrinone use on admission to the cardiac intensive care unit remained independently associated with an increase in the odds of postoperative tachyarrhythmia resulting in an intervention (OR 2.8 [95%CI 1.3–6.0], p=0.007). In conclusion, milrinone use is an independent risk factor for clinically significant tachyarrhythmias in the early postoperative period following congenital heart surgery. PMID:21890079

    The aim of this study was to describe stress symptoms among adolescents before and after scoliosis surgery and to explore correlations with postoperative pain. Scoliosis surgery is a major surgical procedure. Adolescent patients suffer from preoperative stress and severe postoperative pain. Previous studies indicate that there is a risk of traumatisation and psychological complications during the recovery period. A prospective quantitative cohort study with consecutive inclusion of participants. A cohort of 37 adolescent patients aged 13-18. To assess the adolescents' experiences before surgery and at six to eight months after surgery, the Trauma Symptom Checklist for Children - Alternative version, Youth Self-Report and Kiddie Schedule for Affective Disorder and Schizophrenia for children 12-18 were used. The Visual Analogue Scale was used for self-report of postoperative pain on day three. Rates of anxiety/depression and internalising behaviour were significantly higher before surgery than six months after. Preoperative anger, social problems and attention problems correlated significantly with postoperative pain on day three. At follow-up, postoperative pain correlated significantly with anxiety, social problems and attention problems. The results of this study indicate a need for interventions to reduce perioperative stress and postoperative pain to improve the quality of nursing care. Attention to preoperative stress and implementation of interventions to decrease stress symptoms could ameliorate the perioperative process by reducing levels of postoperative pain, anxiety, social and attention problems in the recovery period. © 2016 John Wiley & Sons Ltd.

    Postoperative chylothorax is a relatively rare but potentially fatal complication caused by iatrogenic injury to thoracic duct system, with an incidence ranging from 2 to 4% after major lung surgery or esophagectomy. The pathophysiologic features of chylothorax include dehydration, loss of nutrients and immunological components. Intraopreative prevention is the first step for the management, and treatment options include conservative therapy, percutaneous intervention, and redo-operation. Although the treatment algorithm has not been standardized, chylothorax which is refractory to conservative treatment, or that with high output greater than 1,000 ml/day should be treated aggressively with thoracic duct embolization or redo-operation in a timely fashion. We herein review the anatomy and physiology of thoracic duct system and describe the overview of prevention and each theapeutic options of postoperative chylothorax.

    Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spinal stenosis in prospectively randomized design. We conducted a 1-year prospective, randomized, placebo-controlled, double-blind study to evaluate the impact of vitamin C on the postoperative outcomes after PLIF surgery. A total of 123 eligible patients were randomly assigned to either group A (62 patients with vitamin C) or group B (61 patients with placebo). Patient follow-up was continued for at least 1 year after surgery. The primary outcome measure was pain intensity in the lower back using a visual analogue scale. The secondary outcome measures were: (1) the clinical outcome assessed using the Oswestry Disability Index (ODI); (2) the fusion rate assessed using dynamic radiographs and computed tomography scans; and (3) complications. Pain intensity in the lower back was significantly improved in both groups compared with preoperative pain intensity, but no significant difference was observed between the 2 groups over the follow-up period. The ODI score of group A at the third postoperative month was significantly higher than the score of group B. After the sixth postoperative month, the ODI score of group A was slightly higher than the score of group B; however, this difference was not significant. The fusion rates at 1 year after surgery and the complication rates were not significantly different between the 2 groups. Postoperative pain intensity, the primary outcome measure, was not significantly different at 1 year after surgery between the 2 groups. However, vitamin C may be associated with improving functional status after PLIF surgery, especially during the first 3

    Full Text Available This study tested whether adults with autism spectrum disorder (ASD are at higher risk for pathological game use than typically developing (TD adults. Participants included 119 adults with and without ASD. Participants completed measures assessing daily hours of video game use, percent of free time spent playing video games, and symptoms of pathological game use. The results indicated that adults with ASD endorsed more symptoms of video game pathology than did TD adults. This relationship was strong, enjoying 300,000-to-1 odds in Bayesian model comparison. Results also showed that adults with ASD spent more daily hours playing video games and spent a higher percent of their free time playing video games than did TD adults. Even after adjustment for these differences in daily video game hours and proportion of free time spent on games, model comparisons found evidence for a difference in game pathology scores associated with ASD status. Additionally, escapism motives for playing video games was associated with game pathology scores in both ASD and TD adults, replicating and extending a previous report. In conclusion, the risk for pathological game use appears larger in adults with ASD compared with TD adults. These findings point to pathological game use as a potentially important focus of clinical attention in adults with ASD.

Patients were initially evaluated by pelvic magnetic resonance imaging and found to have distended hematometrocolpos with distal vaginal atresia. All patients underwent pull-through vaginoplasty with similar operative techniques. The average distance from the perineum to the level of the obstruction was 1.84 ± 1.2 cm. Two patients, both with obstructions at greater than 3 cm, experienced stricture formation postoperatively. Four patients (25%) experienced postoperative vaginitis. One patient (6.25%) experienced a postoperative urinary tract infection. Two groups (3 cm or less versus greater than 3 cm) were compared, and the presence of stricture was statistically different based on mean centimeters from perineum prior to pull-through vaginoplasty (P = .038). Distal vaginal atresia is managed with pull-through vaginoplasty. Atresias that extend greater than 3 cm from the perineum are at increased risk for vaginal stricture formation and should be followed to monitor for their formation. Other complications are infrequent and minor. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc. All rights reserved.

    Surgery is an important part of the treatment modalities offered to older patients with cancer. Natural ageing processes lead to deterioration of organ function, making older patients more vulnerable and at risk for experiencing less-favourable outcomes and complications after surgery. Non-pharmaceutical interventions, such as music, may be preferable to medical interventions in older people, who are at risk for adverse effects and drug interactions due to altered physiology and drug metabolism. We aimed to assess the effect of music on postoperative recovery in older patients and to determine the underpinning theoretical models MATERIALS AND METHODS: This systematic review used the databases PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsychINFO, and Répertoire International de Littérature Musicale (RILM). Clinical studies published, until 2015, investigating music as a single intervention for hospitalised patients postoperative, population mean age 60 years or older were selected. All types of postoperative music interventions, consisting of single or more sessions, which take place at a hospital ward. All patient outcomes were included. The search and screening was performed twice, independently, and seventeen articles were finally selected. Four theoretical models were detected underpinning the effect of music on postoperative recovery. The way the music interventions were shaped, varied strongly. Therefore it remained unclear what is the most effective way of performing the music in the postoperative period. Although evidence is still limited, results do show that music has a positive effect on the recovery of older patients after surgery. Pain and anxiety are reduced, and relaxation, cognitive functioning, and patient satisfaction increase during postoperative recovery. No negative side effects of music as an intervention were found and therefore seems a non-harming and non-invasive intervention. It seems worthwhile to

    Full Text Available Recent work has revealed a relationship between pathological video game use and increased impulsivity among children and adolescents. A few studies have also demonstrated increased risk-taking outside of the video game environment following game play, but this work has largely focused on one genre of video games (i.e., racing. Motivated by these findings, the aim of the current study was to examine the relationship between pathological and non-pathological video game use, impulsivity, and risky decision making. The current study also investigated the relationship between experience with two of the most popular genres of video games (i.e., first-person shooter and strategy and risky decision making. Consistent with previous work, approximately 7% of the current sample of college-aged adults met criteria for pathological video game use. The number of hours spent gaming per week was associated with increased impulsivity on a self-report measure and on the temporal discounting task. This relationship was sensitive to the genre of video game; specifically, experience with first-person shooter games was positively correlated with impulsivity, while experience with strategy games was negatively correlated with impulsivity. Hours per week and pathological symptoms predicted greater risk-taking in the risk task and the Iowa Gambling task, accompanied by worse overall performance, indicating that even when risky choices did not pay off, individuals who spent more time gaming and endorsed more symptoms of pathological gaming continued to make these choices. Based on these data, we suggest that the presence of pathological symptoms and the genre of video game (e.g., first-person shooter, strategy may be important factors in determining how the amount of game experience relates to impulsivity and risky-decision making.

    Postoperative nausea and vomiting (PONV) is a complication affecting between 20 and 40% of all surgery patients, with high-risk patients experiencing rates of up to 80%. Recent studies and publications have shed light on the uses of alternative treatment for PONV through their modulation of endogenous opioid neuropeptides and neurokinin ligands. In addition to reducing PONV, hypnosis was reported to be useful in attenuating postoperative pain and anxiety, and contributing to hemodynamic stability. Music therapy has been utilized to deepen the sedation level and decrease patient anxiety, antiemetic and analgesic requirements, hospital length of stay, and fatigue. Isopropyl alcohol and peppermint oil aromatherapy have both been used to reduce postoperative nausea. With correct training in traditional Chinese healing techniques, acupuncture (APu) at the P6 acupoint has also been shown to be useful in preventing early PONV, postdischarge nausea and vomiting, and alleviating of pain. Electro-acupuncture (EAPu), as with APu, provided analgesic and antiemetic effects through release and modulation of opioid neuropeptides. These non-pharmacological modalities of treatment contribute to an overall patient wellbeing, assisting in physical and emotional healing.

    Backround Sugammadex is a reversal agent with well known advantages but it’s effects on haemostasis and bleeding have been a topic of interest. Septoplasty is a common surgical procedure with postoperative respiratory complications and bleeding. The aim of this study is to investigate the effects of sugammadex on postoperative coagulation parameters and bleeding after septoplasty procedure. Material/Methods In this randomized controlled study, fifty patients were grouped into two groups; neostigmine (Group N) vs. sugammadex (Group S). For the evaluation of PT, aPTT and INR, blood samples were taken for at the postoperative 120th minutes and alteration of these values with respect to preoperative values were documented. Postoperative bleeding was measured by evaluating the amount of blood absorbed on the nasal tip dressing during 3 hours postoperatively. Results Postoperative bleeding amount was significantly higher in the Group S compared to Group N (p=0.013). No significant difference was observed between two groups according to coagulation parameters (PT; p=0.953, aPTT; p=0.734, INR; p=0.612). Conclusions Sugammadex was associated with higher amount of postoperative bleeding than neostigmine in septoplasty patients. In surgical procedures having high risk of bleeding the safety of sugammadex need to be verified. PMID:26271275

    Full Text Available The impact of glucose control on surgical-site infection (SSI and death remains unclear. We examined how pre- and post-operative glucose levels and their variability are associated with the risk of SSI or in-hospital death.This retrospective cohort study employed data on 13,800 hospitalized patients who underwent a surgical procedure at a large referral hospital in New York between 2006 and 2008. Over 20 different sources of electronic data were used to analyze how thirty-day risk of SSI and in-hospital death varies by glucose levels and variability. Maximum pre- and post-operative glucose levels were determined for 72 hours before and after the operation and glucose variability was defined as the coefficient of variation of the glucose measurements. We employed logistic regression to model the risk of SSI or death against glucose variables and the following potential confounders: age, sex, body mass index, duration of operation, diabetes status, procedure classification, physical status, emergency status, and blood transfusion.While association of pre- and post-operative hyperglycemia with SSI were apparent in the crude analysis, multivariate results showed that SSI risk did not vary significantly with glucose levels. On the other hand, in-hospital deaths were associated with pre-operative hypoglycemia (OR = 5.09, 95% CI (1.80, 14.4 and glucose variability (OR = 1.14, 95% CI (1.03, 1.27 for 10% increase in coefficient of variation.In-hospital deaths occurred more often among those with pre-operative hypoglycemia and higher glucose variability. These findings warrant further investigation to determine whether stabilization of glucose and prevention of hypoglycemia could reduce post-operative deaths.

    To describe the incidence of postoperative endophthalmitis after cataract surgery in a multiethnic Asian population over an 11-year period, compare the endophthalmitis rates before and after the use of intracameral antibiotic agents, and identify potential risk factors for endophthalmitis. Department of Ophthalmology, Tan Tock Seng Hospital, Singapore. Cohort study. The incidence and risk factors for postoperative endophthalmitis in patients who had cataract surgery over 11 years were reviewed. Subconjunctival antibiotic agents only were administered over 7 years; in the subsequent 4 years, intracameral cefazolin (1.0 mg/0.1 mL) was used. The overall incidence of postoperative endophthalmitis in 50,177 was 0.042%. Over the 7 years without intracameral antibiotics, the endophthalmitis rate was 0.064% (19/29,539). With the use of intracameral cefazolin, the incidence decreased to 0.01% (2/20,638) (multivariate odds ratio [OR], 13.6; 95% confidence interval [CI], 3.15-58.58; P<.001). The independent risk factors for endophthalmitis were age (OR, 1.05; 95% CI, 1.01-1.09; P=.025) and male sex (0.06% versus 0.02%; OR, 2.96; 95% CI; 1.15-7.65; P=.025). There was a significant reduction in the rate of postoperative endophthalmitis in a multiethnic Asian population with the use of intracameral cefazolin. Men and older patients were at a higher risk for endophthalmitis. No author has a financial or proprietary interest in any material or method mentioned. Copyright © 2012 ASCRS and ESCRS.

    Postoperative peritonitis is still a life-threatening complication after abdominal surgery and approximately 10,000 patients annually develop postoperative peritonitis in Germany. Early recognition and diagnosis before the onset of sepsis has remained a clinical challenge as no single specific screening test is available. The aim of therapy is a rapid and effective control of the source of infection and antimicrobial therapy. After diagnosis of diffuse postoperative peritonitis surgical revision is usually inevitable after intestinal interventions. Peritonitis after liver, biliary or pancreatic surgery is managed as a rule by means of differentiated therapy approaches depending on the severity.

    Few data are available in the literature on risk factors for postoperative vomiting (POV) in children. The aim of the study was to establish independent risk factors for POV and to construct a pediatric specific risk score to predict POV in children. Characteristics of 2392 children operated under general anesthesia were recorded. The dataset was randomly split into an evaluation set (n = 1761), analyzed with a multivariate analysis including logistic regression and backward stepwise procedure, and a validation set (n = 450), used to confirm the accuracy of prediction using the area under the receiver operating characteristic curve (ROCAUC ), to optimize sensitivity and specificity. The overall incidence of POV was 24.1%. Five independent risk factors were identified: stratified age (>3 and 13 years: adjusted OR 2.46 [95% CI 1.75-3.45]; ≥6 and ≤13 years: aOR 3.09 [95% CI 2.23-4.29]), duration of anesthesia (aOR 1.44 [95% IC 1.06-1.96]), surgery at risk (aOR 2.13 [95% IC 1.49-3.06]), predisposition to POV (aOR 1.81 [95% CI 1.43-2.31]), and multiple opioids doses (aOR 2.76 [95% CI 2.06-3.70], P risk score ranged from 0 to 6. The model yielded a ROCAUC of 0.73 [95% CI 0.67-0.78] when applied to the validation dataset. Independent risk factors for POV were identified and used to create a new score to predict which children are at high risk of POV. © 2014 John Wiley & Sons Ltd.

    Purpose To investigate the impact of modern postoperative radiotherapy (PORT) on overall survival (OS) for patients with N2 non–small-cell lung cancer (NSCLC) treated nationally with surgery and adjuvant chemotherapy. Patients and Methods Patients with pathologic N2 NSCLC who underwent complete resection and adjuvant chemotherapy from 2006 to 2010 were identified from the National Cancer Data Base and stratified by use of PORT (≥ 45 Gy). A total of 4,483 patients were identified (PORT, n = 1,850; no PORT, n = 2,633). The impact of patient and treatment variables on OS was explored using Cox regression. Results Median follow-up time was 22 months. On univariable analysis, improved OS correlated with younger age, treatment at an academic facility, female sex, urban population, higher income, lower Charlson comorbidity score, smaller tumor size, multiagent chemotherapy, resection with at least a lobectomy, and PORT. On multivariable analysis, improved OS remained independently predicted by younger age, female sex, urban population, lower Charlson score, smaller tumor size, multiagent chemotherapy, resection with at least a lobectomy, and PORT (hazard ratio, 0.886; 95% CI, 0.798 to 0.988). Use of PORT was associated with an increase in median and 5-year OS compared with no PORT (median OS, 45.2 v 40.7 months, respectively; 5-year OS, 39.3% [95% CI, 35.4% to 43.5%] v 34.8% [95% CI, 31.6% to 38.3%], respectively; P = .014). Conclusion For patients with N2 NSCLC after complete resection and adjuvant chemotherapy, modern PORT seems to confer an additional OS advantage beyond that achieved with adjuvant chemotherapy alone.

    Full Text Available Background and Aims: Post-operative nausea and vomiting (PONV has an 80% incidence in high-risk patients. This is despite the availability of several antiemetic drugs. Selective 5-hydroxytryptamine type 3 (5-HT 3 receptor antagonists are considered first-line for prophylaxis, ondansetron being the most commonly used agent. Ramosetron, another selective 5-HT 3 receptor antagonist, is more potent and longer acting than ondansetron. This study was conducted to evaluate the antiemetic efficacy of ramosetron in comparison with ondansetron in patients at a high risk of PONV. Methods: This was a prospective randomised double-blind study carried out over a 6-month period in which 206 patients with at least two risk factors for PONV were randomised to receive ramosetron 0.3 mg or ondansetron 8 mg, 30 min before the end of surgery. The incidence of PONV, severity of nausea and need for rescue antiemetic were recorded over the next 24 h. Primary outcome was the incidence of PONV. Secondary outcomes included severity of nausea and need for rescue. The data were analysed using the Predictive Analytics Software (PASW, version 18: Chicago, IL, USA. Results: The incidence of PONV was found to be 35% in the ramosetron group as opposed to 43.7% in the ondansetron group (P = 0.199. Need for rescue antiemetic was 23.3% in the ramosetron group and 32% in the ondansetron group (P = 0.156 in the 24 h following surgery. Conclusion: Ramosetron 0.3 mg and ondansetron 8 mg were equally effective in reducing the incidence of PONV in high risk patients.

  11. The Effect of Transdermal Scopolamine for the Prevention of Postoperative Nausea and Vomiting

    Full Text Available Postoperative nausea and vomiting is one of the most common and undesirable complaints recorded in as many as 70%-80% of high-risk surgical patients. The current prophylactic therapy recommendations for PONV management stated in the Society of Ambulatory Anesthesia guidelines should start with monotherapy and patients at moderate to high risk, a combination of antiemetic medication should be considered. Consequently, if rescue medication is required, the antiemetic drug chosen should be from a different therapeutic class and administration mode than the drug used for prophylaxis. The guidelines restrict the use of dexamethasone, transdermal scopolamine, aprepitant, and palonosetron as rescue medication 6 hours after surgery. In an effort to find a safer and reliable therapy for postoperative nausea and vomiting, new drugs with antiemetic properties and minimal side effects are needed, and scopolamine may be considered an effective alternative. Scopolamine is a belladonna alkaloid, α-(hydroxymethyl benzene acetic acid 9-methyl-3-oxa-9-azatricyclo non-7-yl ester, acting as a nonselective muscarinic antagonist and producing both peripheral antimuscarinic and central sedative, antiemetic, and amnestic effects. The empirical formula is C17H21NO4 and its structural formula is a tertiary amine L-(2-scopolamine (tropic acid ester with scopine; MW = 303.4. Scopolamine became the first drug commercially available as a transdermal therapeutic system used for extended continuous drug delivery during 72 hours. Clinical trials with transdermal scopolamine have consistently demonstrated its safety and efficacy in postoperative nausea and vomiting. Thus, scopolamine is a promising candidate for the management of postoperative nausea and vomiting in adults as a first line monotherapy or in combination with other drugs. In addition, transdermal scopolamine might be helpful in preventing postoperative discharge nausea and vomiting owing to its long

    Diseases of the nervous system and sense organs have become the most significant pathologies of Chernobyl clean-up workers during the last four years. The aim of this work was to evaluate the incidence of eye disorders among Chernobyl clean-up workers to provide more information for health specialists. During the last 10 years, the most common eye pathology has been angiopathia retinae, followed by myopia and cataracta. Statistical analyses showed that the clean-up workers have higher risk to develop angiopathia retinae than the control group. (author)

    Purpose: To retrospectively compare the efficacy of radiation therapy (RT) and chemotherapy plus RT (CRT) for the postoperative treatment of node-positive thoracic esophageal squamous cell carcinoma (TESCC) and to determine the incidence and severity of toxic reactions. Methods and Materials: We retrospectively reviewed data from 304 patients who had undergone esophagectomy with 3-field lymph node dissection for TESCC and were determined by postoperative pathology to have lymph node metastasis without distant hematogenous metastasis. Of these patients, 164 underwent postoperative chemotherapy (cisplatin 80 mg/m{sup 2}, average days 1-3, plus paclitaxel 135 mg/m{sup 2}, day 1; 21-day cycle) plus RT (50 Gy), and 140 underwent postoperative RT alone. Results: The 5-year overall survival rates for the CRT and RT groups were 47.4% and 38.6%, respectively (P=.030). The distant metastasis rate, the mixed (regional lymph node and distant) metastasis rate, and the overall recurrence rate were significantly lower in the CRT group than in the RT group (P<.05). However, mild and severe early toxic reactions, including neutropenia, radiation esophagitis, and gastrointestinal reaction, were significantly more common in the CRT group than in the RT group (P<.05). No significant differences in incidence of late toxic reactions were found between the 2 groups. Conclusions: Our results show that in node-positive TESCC patients, postoperative CRT is significantly more effective than RT alone at increasing the overall survival and decreasing the rates of distant metastasis, mixed metastasis, and overall recurrence. Severe early toxic reactions were more common with CRT than with RT alone, but patients could tolerate CRT.

    The Health Services, not only the Italian one, is under pressure because of request for improving treatment quality and the financial need for reorganization and cost-saving. It's required a rationalization of intervention, together with a careful choice of the best and cheapest techniques and the demonstration of their efficacy. The anaesthesia service activity, in a period of cost rationalization and funds restriction should be aimed to appropriate outcome measures corrected by both patient's risk factors and surgical-anaesthesiological case-mix. The development of a complete strategy for surgical pain management might run into two phases. The first phase, internal and mono-specialistic, should develop like the creation of an Acute Pain Team. The main processes are: focusing the problem (charge of the care), training, information, teaching methodology (timing, methods, drugs, techniques, etc.) and the audit (before and after changes). The main aims are the evaluation of the level of analgesia and pain relief or patient's satisfaction which are partial endpoints useful to demonstrate the improvement and the efficacy of the new pain management strategies. The second phase, multidisciplinary, is directed toward the creation of a Postoperative Evaluation Team. The main objective is to set up a collaborative clinical group able to identify the criteria for quality, efficacy and safety. The major purpose is the evaluation of major outcome measures: surgical outcome, morbidity, mortality and length of hospitalization. The improvement in the quality of postoperative pain treatment goes through a better organization and a progressive increase of the already available therapy. The achievement of the result and the quality projects depend on the interaction among staff members with different behaviours and settings. Internal teaching and training, continuous education for doctors and nurses, and external information, marketing and improvement of attractive capability of

    Patients undergoing transsphenoidal surgery (TSS) have an anterior skull base defect that limits the use of positive pressure ventilation post-operatively. Obstructive sleep apnea (OSA) can be seen in these patients and is treated with continuous positive airway pressure (CPAP). In our study we documented the incidence of pre-existing OSA and reported the incidence of diagnosed pneumocephalus and its relationship to OSA. A retrospective review was conducted from a surgical outcomes database. Electronic medical records were reviewed, with an emphasis on diagnosis of OSA and documented symptomatic pneumocephalus. A total of 324 patients underwent 349 TSS for sellar mass resection. The average body mass index of the study cohort was 32.5kg/m(2). Sixty-nine patients (21%) had documented OSA. Only 25 out of 69 (36%) had a documented post-operative CPAP plan. Out of all 349 procedures, there were two incidents of pneumocephalus diagnosed. Neither of the patients had pre-existing OSA. One in five patients in our study had pre-existing OSA. Most patients returned to CPAP use within several weeks of TSS for resection of a sellar mass. Neither of the patients with pneumocephalus had pre-existing OSA and none of the patients with early re-initiation of CPAP developed this complication. This study provides preliminary evidence that resuming CPAP early in the post-operative period might be less dangerous than previously assumed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Inadvertent postoperative hypothermia (a drop in core body temperature to below 36°C) occurs as an effect of surgery when anaesthetic drugs and exposure of the skin for long periods of time during surgery result in interference with normal temperature regulation. Once hypothermia has occurred, it is important that patients are rewarmed promptly to minimise potential complications. Several different interventions are available for rewarming patients. To estimate the effectiveness of treating inadvertent perioperative hypothermia through postoperative interventions to decrease heat loss and apply passive and active warming systems in adult patients who have undergone surgery. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 2), MEDLINE (Ovid SP) (1956 to 21 February 2014), EMBASE (Ovid SP) (1982 to 21 February 2014), the Institute for Scientific Information (ISI) Web of Science (1950 to 21 February 2014) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EBSCO host (1980 to 21 February 2014), as well as reference lists of articles. We also searched www.controlled-trials.com and www.clincialtrials.gov. Randomized controlled trials of postoperative warming interventions aiming to reverse hypothermia compared with control or with each other. Three review authors identified studies for inclusion in this review. One review author extracted data and completed risk of bias assessments; two review authors checked the details. Meta-analysis was conducted when appropriate by using standard methodological procedures as expected by The Cochrane Collaboration. We included 11 trials with 699 participants. Ten trials provided data for analysis. Trials varied in the numbers and types of participants included and in the types of surgery performed. Most trials were at high or unclear risk of bias because of inappropriate or unclear randomization procedures, and because blinding of assessors and participants generally was

    Purpose: This retrospective study assessed the outcome and patterns of failure for patients with malignant submandibular tumors treated with surgery and postoperative radiation. Methods and Materials: Between 1965 and 1995, 83 patients aged 11-83 years old received postoperative radiotherapy after resection of submandibular gland carcinomas. The most common radiation technique was an appositional field to the submandibular gland bed using electrons either alone or mixed with photons. Primary tumor bed doses ranged from 50 to 69 Gy (median, 60 Gy). Regional lymph nodes (ipsilateral Levels I-IV) were irradiated in 66 patients to a median dose of 50 Gy. Follow-up time ranged from 5 to 321 months (median, 82 months). Results: Actuarial locoregional control rates were 90%, 88%, and 88% at 2, 5, and 10 years, respectively. The corresponding disease-free survival rates were 76%, 60%, and 53%, because 27 of 74 patients (36%) who attained locoregional control developed distant metastases. Adenocarcinoma, high-grade histology, and treatment during the earlier years of the study were associated with worse locoregional control and disease-free survival. The median survival times for patients with and without locoregional control were 183 months and 19 months, respectively. Actuarial 2-, 5-, and 10-year survival rates were 84%, 71%, and 55%, respectively. Late complications occurred in 8 patients (osteoradionecrosis, 5 patients). Conclusions: High-risk cancers of the submandibular gland have a historic control rate of approximately 50% when treated with surgery alone. In the current series, locoregional control rates for high-risk patients with submandibular gland cancers treated with surgery and postoperative radiotherapy were excellent, with an actuarial locoregional control rate of 88% at 10 years

    Purpose : To obtain the optical treatment method in patients with endometrial carcinoma(clinical stage FIGO I, II) by comparative analysis between preoperative radiotherapy(pre-op R) and postoperative radiotherapy(post-op RT). Materials and Methods : A retrospective review of 62 endometrial carcinoma patients referred to the Yonsei Cancer Center for radiotherapy between 1985 and 1991 was undertaken. Of 62 patients, 19 patients(Stage I; 12 patients, Stage II; 7 patients) received pre-op RT before TAH(Total Abdominal Hysterectomy) and BSO(Bilateral Salphingoophorectomy) (Group 1) and 43 patients( Stage 1; 32 patients, Stage 2; 11 patients) received post-op RT after TAH and BSO (Group 2). Pre-op irradiation was given 4-6 weeks prior to surgery and post-op RT was administered on 4-5 weeks following surgery. All patients exept 1 patient(Group2; ICR alone) received external irradiation. Seventy percent(13/19) of pre-op RT group and 54 percent(23/42) of post-op RT group received external pelvic irradiation and intracavitary radiation therapy(ICR). External radiation dose was 39.6-55Gy(median 45Gy) in 5-6 week through opposed AP/PA fields or 4-field box technique treating daily, five days per week, 180cGy per fraction. ICR doses were prescribed to point A(20-39.6 Gy, median 39Gy) in Group 1 and 0.5cm depth from vaginal surface (18-30 Gy, median 21Gy) in Group2. Results : The overall 5 year survival rate was 95%. No survival difference between pre-op and post-op RT group.(89.3% vs 97.7%, p>0.1) There was no survival difference by stage, grade and histology between two groups. The survival rate was not affected by presence of residual tumor of surgical specimen after pre-op RT in Group 1(p>0.1), but affected by presence of lymph node metastasis in post-op RT group(p<0.5). The complication rate of pre-op RT group was higher than post-op RT.(16% vs 5%) Conclusion : Post-op radiotherapy offers the advantages of accurate surgical-pathological staging and low complication rate

    Postoperative ileus (POI) after colorectal surgery is associated with prolonged hospital stay and increased costs. The aim of this study is to investigate pre-, intra-, and postoperative risk factors associated with the development of POI in patients undergoing laparoscopic partial colectomy. Patients operated between 2004 and 2008 were retrospectively identified from a prospectively maintained database, and clinical, metabolic, and pharmacologic data were obtained. Postoperative ileus was defined as the absence of bowel function for 5 or more days or the need for reinsertion of a nasogastric tube after starting oral diet in the absence of mechanical obstruction. Associations between likelihood of POI and study variables were assessed univariably by using χ tests, Fisher exact tests, and logistic regression models. A scoring system for prediction of POI was constructed by using a multivariable logistic regression model based on forward stepwise selection of preoperative factors. A total of 413 patients (mean age, 58 years; 53.5% women) were included, and 42 (10.2%) of them developed POI. Preoperative albumin, postoperative deep-vein thrombosis, and electrolyte levels were associated with POI. Age, previous abdominal surgery, and chronic preoperative use of narcotics were independently correlated with POI on multivariate analysis, which allowed the creation of a predictive score. Patients with a score of 2 or higher had an 18.3% risk of POI (P POI can be predicted by using a preoperative scoring system. Addressing the postoperative factors may be expected to reduce the incidence of this common complication in high-risk patients.
