    Full Text Available CONTEXT AND OBJECTIVE: Prostate biopsy is not a procedure without risk. There is concern about major complications and which antibiotics are best for routine use before these biopsies. The objective was to determine the rate of complications and the possible risk factors in prostate biopsies. DESIGN AND SETTING: Prospective study, Faculdade de Medicina de Botucatu. METHODS: Transrectal ultrasound (TRUS guided prostate biopsies were carried out in 174 patients presenting either abnormality in digital rectal examinations (DRE or levels higher than 4 ng/ml in prostate-specific antigen (PSA tests, or both. RESULTS: Hemorrhagic complications were the most common (75.3%, while infectious complications occurred in 19% of the cases. Hematuria was the most frequent type (56%. Urinary tract infection (UTI occurred in 16 patients (9.2%. Sepsis was observed in three patients (1.7%. The presence of an indwelling catheter was a risk factor for infectious complications (p < 0.05. Higher numbers of biopsies correlated with hematuria, rectal bleeding and infectious complications (p < 0.05. The other conditions investigated did not correlate with post-biopsy complications. CONCLUSIONS: Post-biopsy complications were mostly self-limiting. The rate of major complications was low, thus showing that TRUS guided prostate biopsy was safe and effective. Higher numbers of fragments taken in biopsies correlated with hematuria, rectal bleeding and infectious complications. An indwelling catheter represented a risk factor for infectious complications. The use of aspirin was not an absolute contraindication for TRUS.

    Despite advances in surgical techniques and products for stoma care, stoma-related complications are still common. A retrospective analysis was performed of the medical records of 462 consecutive patients (295 [63.9%] female, 167 [36.1 %] male, mean age 55.5 ± 15.1 years, mean body mass index [BMI] 25.1 ± 5.2) who had undergone stoma creation at the Gastroenterological Surgery Clinic of Turkiye Yuksek İhtisas Teaching and Research Hospital between January 2008 and December 2012 to examine the incidence of early (ie, within 30 days after surgery) stoma complications and identify potential risk factors. Variables abstracted included gender, age, and BMI; existence of malignant disease; comorbidities (diabetes mellitus, hypertension, coronary artery disease, chronic respiratory disease); use of neoadjuvant chemoradiotherapy; permanent or temporary stoma; type of stoma (loop/end stoma); stoma localization; and the use of preoperative marking of the stoma site. Data were entered and analyzed using statistical software. Descriptive statistics, chi-squared, and Mann-Whitney U tests were used to describe and analyze all variables, and logistic regression analysis was used to determine independent risk factors for stoma complications. Ostomy-related complications developed in 131 patients (28.4%) Of these, superficial mucocutaneous separation was the most frequent complication (90 patients, 19.5%), followed by stoma retraction (15 patients, 3.2%). In univariate analysis, malignant disease (P = .025), creation of a colostomy (P = .002), and left lower quadrant stoma location (P toma complication. Only stoma location was an independent risk factor for the development of a stoma complication (P = .044). The rate of stoma complications was not significantly different between patients who underwent nonemergent surgery (30% in patients preoperatively sited versus 28.4% not sited) and patients who underwent emergency surgery (27.1%). Early stoma complication rates were higher

    Neonatal ostomies, either temporary or permanent, are created for numerous reasons. Limited attention has been given to understanding what factors might place infants at risk for surgical wound complications. The purpose of the study is to identify factors associated with risk of significant abdominal wound complications (wound dehiscence and wound infection) following neonatal ostomy creation. This is a retrospective chart review of infants undergoing ostomy between January 2009 and December 2013 at the University of Alberta Hospital. 66 infants were identified of which 18.2% (12/66) had wound complications. Variables associated with wound dehiscence included: findings of bowel necrosis during laparotomy (7/9 wound dehiscence, 18/57 none, p=0.008), perioperative sepsis (3/9 wound dehiscence, 3/57 none, p=0.006), and perioperative blood transfusion (9/9 wound dehiscence, 30/57 none, p=0.007). Wound infection was not predicted by any variables collected. Neonates undergoing creation of an ostomy appear to be at substantial risk for wound complications. As wound complications are significant issues for infants undergoing surgery, emerging strategies should be explored to either avoid ostomy creation or promote wound healing.

    CT-guided transthoracic core-needle biopsy (TTNB) is frequently used for the diagnosis of lung nodules. The aim of this study is to describe TTNBs' complications and to investigate predictive factors of complications. All consecutive TTNBs performed in three centers between 2006 and 2012 were included. Binary logistic regression was used for multivariate analysis. Overall, 970 TTNBs were performed in 929 patients. The complication rate was 34% (life-threatening complication in 6%). The most frequent complications were pneumothorax (29% included 4% which required chest-tube) and hemoptysis (5%). The mortality rate was 0.1% (n=1). In multivariate analysis, predictive factor for a complication was small target size (AOR=0.984; 95% CI [0.976-0.992]; P<0.001). This predictive factor was also found for occurrence of life-threatening complication (AOR=0.982; [0.965-0.999]; P=0.037), of pneumothorax (AOR=0.987; [0.978-0.995]; P=0.002) and of hemoptysis (AOR=0.973; [0.951-0.997]; P=0.024). One complication occurred in one-third of TTNBs. The proportion of life-threatening complication was 6%. A small lesion size was predictive of complication occurrence.

    Risk factors for vascular complications in polycythemia vera (PV) include laboratory and clinical findings. Among laboratory values, the hematocrit has been clearly associated with thrombosis, particularly in the cerebral circulation. Platelet count is a possible but not yet clearly established predictor of vascular complications. Platelet function tests are of little help in prognostic evaluation because most attempts to correlate these abnormalities with clinical events have been disappointing. Clinical predictors of thrombosis include increasing age and a previous history of vascular events. Identifying risk factors for thrombosis is important to initiate therapy. Phlebotomy is associated with an increased incidence of thrombosis in the first 3 to 5 years, whereas chemotherapy may induce a higher risk of secondary malignancies after 7 to 10 years of follow-up. New cytoreductive drugs virtually devoid of mutagenic risk include interferon-alpha and anagrelide, but their role in reducing thrombotic complications remains to be demonstrated. Antithrombotic drugs, such as aspirin, are frequently used in PV, despite doubts regarding safety and efficacy. Two recent studies from the Gruppo Italiano Studio Policitemia Vera (GISP) assessed the rate of major thrombosis as well as the tolerability of low-dose aspirin in PV patients. These investigations created a favorable scenario for launching a European collaborative clinical trial (ECLAP study) aimed at testing the efficacy of low-dose aspirin in preventing thrombosis and prolonging survival in patients with PV.

    This study evaluates baseline patient characteristics and surgical parameters for risk factors of medical complications in ASD patients received posterior long level internal fixation. Analysis of consecutive patients who underwent posterior long-level instruction fixation for adult degenerative scoliosis (ADS) with a minimum of two year follow-up was performed. Pre-operative risk factors, intraoperative variables, peri-operative radiographic parameters, and surgical-related risk factors were collected to analyze the effect of risk factors on medical complications. Patients were separated into groups with and without medical complication. Then, complication group was further classified as major or minor medical complications. Potential risk factors were identified by univariate testing. Multivariate logistic regression was used to evaluate independent predictors of medical complications. One hundred and thirty-one ADS patients who underwent posterior long segment pedicle screws fixation were included. Total medical complication incidence was 25.2%, which included infection (12.2%), neurological (11.5%), cardiopulmonary (7.6%), gastrointestinal (6.1%), and renal (1.5%) complications. Overall, 7.6% of patients developed major medical complications, and 17.6% of patients developed minor medical complications. The radiographic parameters of pre-operative and last follow-up had no significant difference between the groups of medical complications and the major or minor medical complications subgroups. However, the incidence of cerebrospinal fluid leak (CFL) in patients who without medical complications was much lower than that with medical complications (18.4 vs. 42.4%, P = 0.005). Independent risk factors for development of medical complications included smoking (OR = 6.45, P = 0.012), heart disease (OR = 10.07, P = 0.012), fusion level (OR = 2.12, P = 0.001), and length of hospital stay (LOS) (OR = 2.11, P = 0.000).

    Tissue-expander (TE) placement followed by implant exchange is currently the most popular method of breast reconstruction. There is a relative paucity of data demonstrating patient factors that predict complications specifically by stage of surgery. The present study attempts to determine what complications are most likely to occur at each stage and how the risk factors for complications vary by stage of reconstruction. A retrospective chart review was performed on all 1275 patients who had TEs placed by the 2 senior authors between 2004 and 2013. Complication rates were determined at each stage of reconstruction, and these rates were further compared between patients who had pre-stage I radiation, post-stage I radiation, and no radiation exposure. Multivariate logistic regression was used to identify independent predictors of complications at each stage of reconstruction. A total of 1639 consecutive TEs were placed by the senior authors during the study period. The overall rate for experiencing a complication at any stage of surgery was 17%. Complications occurred at uniformly higher rates during stage I for all complications (92% stage I vs 7% stage II vs 1% stage III, P higher intraoperative percent fill (OR, 3.3; 95% CI, 1.7-6.3). Post-stage I radiation was the only independent risk factor for a stage II complication (OR, 4.5; 95% CI, 1.4-15.2). Complications occur at higher rates after stage I than after stage II, and as expected, stage III complications are exceedingly rare. Risk factors for stage I complications are different from risk factors for stage II complications. Body mass index and smoking are associated with complications at stage I, but do not predict complications at stage II surgery. The stratification of risk factors by stage of surgery will help surgeons and patients better manage both risk and expectations.

    Deep brain stimulation (DBS) has been recognized as an efficacious treatment for movement disorders. Its beneficial effects however may be lost due to skin complications such as erosions or infections over the implanted foreign material. We sought to document skin complications in the entire Parkinson's disease patient population who received a DBS system at the Marburg/Kassel implantation centre since the start of our DBS program in January 2002 to analyze frequency, time course, and possible risk factors. We investigated 85 consecutive patients with Parkinson's disease (PD) from a single center/single surgeon DBS series for the occurrence of skin complications and analyzed localization, time course, and possible risk factors. Mean follow-up was 3 years (range 1-7 years). In total, 21/85 patients (24.7%) suffered a total of 30 single skin complications. Sixty percent of all incidents occurred within the first post-operative year. Forty percent of all incidents occurred later than the first year following primary implantation. Complications involved the burr hole cap in 37%, the course of the cables in 33%, and the impulse generator (IPG) site in 30%. Six of 21 patients suffered recurring skin complications. Eight patients permanently lost their DBS system. Factor analysis for age, gender, disease duration, disease severity, the incidence of hypertension or diabetes as well as a 2-day period with externalized electrodes for continuous test stimulation did not have any statistically significant impact on skin complications. We conclude that (1) PD patients have a risk for skin complications after DBS as long as the system remains in situ and (2) there are at present no identifiable risk factors for skin complications after DBS, other than PD itself.

    Peptic ulcer perforation (PUP) is a very serious condition that leads to excessive complications and mortality. This study aimed to explore the possible prognostic factors and complications in patients with perforated peptic ulcer operation. A 6-year retrospective cohort study in Nakornping Hospital between January 1, 2005 and December 31, 2010 was conducted. The study included 912 patients who underwent PUP surgery. Patient characteristics were analyzed by using frequency, percentage, mean (standard deviation) and median (range). A comparison between groups was made. The Pearson's Chi-squared or Fisher's exact test was used for categorical variables, as appropriate. The Student's t test was used for continuous variables with normal distribution, and Wilcoxon rank sum test was performed for continuous variables with non-normal distributions. Exponential risk regression analysis was performed to estimate the relative risk (RR) for the prognostic factors with a probability value of 3 h (RR: 9.83; 95% CI: 1.61-59.66); unplanned admission to ICU (RR: 9.22; 95% CI: 1.55 - 54.68); and prolonged ventilation > 24 h (RR: 9.02; 95% CI: 0.42 - 9.98) were associated with post-operative PUP complications. Post-operative complications developed in 87 (9.54%) patients with 135 complications: 11 (1.21%) patients underwent re-operation, 32 (3.51%) patients suffered with surgical site infection, 74 (8.11%) patients encountered with pneumonia and 18 (1.97%) patients died. Post-operative complications including surgical site infection (incidence rate ratio (IRR): 2.00; 95% CI: 0.76 - 5.27), re-operation (IRR: 2.65; 95% CI: 0.73 - 9.62) and pneumonia (IRR: 6.97; 95% CI: 6.30 - 7.70) tend to be associated with mortality. The risk ratio showed a trend towards an increased risk for post-operative mortality with smaller values. However, this trend was not statistically significant. The findings might have clinical importance as to optimize the surgical management of PUP and to minimize the

    Mandible fractures account for 36 to 70 percent of all facial fractures. Despite their high prevalence, the literature lacks a comprehensive review of demographics, fracture patterns, timing of management, antibiotic selection, and outcomes, particularly when evaluating pediatric versus adult patients. The authors aim to determine the complication and infection rates after surgical treatment of mandibular fractures and the bacterial isolates and antibiotic sensitivities from mandible infections after open reduction and internal fixation at their institution. Data were collected retrospectively for all mandible fractures treated at the authors' institution between 2003 and 2013. Patients were divided into pediatric (younger than 16 years) and adult (16 years or older) subgroups. Demographics, fracture location, fracture cause, comorbidities, antibiotic choice, and subsequent complications and infections were analyzed. Data were evaluated using appropriate statistical tests for each variable. Three hundred ninety-five patients were evaluated. Demographics and fracture cause were similar to those reported in current literature. Of the 56 pediatric patients, complications occurred in 5.6 percent. Time from injury to operative intervention did not affect outcome. The complication rate was 17.5 percent and the infection rate was 9.4 percent in the adult subgroup. Time from injury to operative intervention, sex, and edentulism were not significant predictors of complication or infection. Tobacco use, number of fractures, number of fractures fixated, and surgical approach were predictors of complication and infection. Perioperative ampicillin-sulbactam had a significantly lower risk of infection. Certain demographic and operative factors lead to significantly higher risks of complications after surgical management of mandibular fractures. Ampicillin-sulbactam provides effective antibiotic prophylaxis. Risk factor modification may improve outcomes. Risk, IV.

    PURPOSE. To evaluate various postoperative complications and their risk factors in hip fracture patients. METHODS. 207 female and 87 male consecutive patients (mean age, 78.1 years) who underwent surgical (n=242) or conservative (n=52) treatment for closed fractures of the femoral neck (n=157) or peritrochanter (n=137) were prospectively studied. The types of complication and outcome were recorded. The comorbidity status of the patients was categorised based on the American Society of Anesthesiologists (ASA) classification. Complications and their associations with various risk factors and mortality were analysed. RESULTS. For all patients, the mean length of hospitalisation was 14.6 days. For the 242 patients who underwent surgical treatment after a mean of 3.6 days, 56.8% of them had at least one complication. Acute urinary retention (39.3%) and urinary tract infection (24.0%) were most common. Patients with ASA grade III or higher had 2.3 fold higher risk of developing complications than those with lower-grade comorbidity, whereas patients with delayed operation (>48 hours after presentation) had 1.8 fold higher risk of developing complications than those without delayed operation. Four patients died in hospital: 2 from myocardial infarction and 2 from upper gastrointestinal bleeding. CONCLUSION. Complications after hip fracture surgery were common. Advanced age, high ASA status, and delay in surgery were associated with higher complication rates. Operations should be performed on medically fit patients as early as possible.

    Recent studies have suggested that a smaller glans penis size may be associated with a higher likelihood of complications after hypospadias repair. Accurate identification of risk factors other than the well-understood variable of meatal location would allow development of better prognostic models and individualized risk stratification. To test the hypothesis that a smaller width of the glans penis predicts adverse outcomes after hypospadias surgery. Prospectively recorded clinical data were reviewed from a single-institution registry of primary hypospadias repairs performed between 2011 and 2014. Follow-up records were examined for occurrence of complications. Urethroplasty complications were defined to include meatal stenosis, dehiscence, urethrocutaneous fistula, urethral stricture, and/or urethral diverticulum. The subset of meatal stenosis and dehiscence were regarded as glanular complications. Regression analyses were performed to determine association between glans width and occurrence of complications. Because pre-operative androgen stimulation is known to increase glans penis size, separate subgroup analyses were included of patients with and without pre-operative use of testosterone cream. A total of 159 patients met criteria for inclusion in the study cohort: 140 patients underwent a single-stage repair, while 19 patients had a two-stage repair. The median glans penis width was 15 mm (range 10-22). Eighty-four patients (53%) received testosterone cream pre-operatively and had a significantly wider glans penis than the 75 patients who did not (median 15.5 vs 14 mm; P penis width was not a risk factor for complications after hypospadias repair. This finding differs from the results of other recent studies and encourages further research into the value of measuring penile parameters in patients undergoing hypospadias repair.

    Full Text Available Background: Neurological complications are common after orthotopic liver transplantation (OLT. We aimed to characterize the risk factors associated with neurological complications and mortality among patients who underwent OLT in the post-model for end-stage liver disease (MELD era.Methods: In a retrospective review, we evaluated 227 consecutive patients at the Keck Hospital of the University of Southern California before and after OLT to define the type and frequency of and risk factors for neurological complications and mortality.Results: Neurological complications were common (n=98, with encephalopathy being most frequent (56.8%, followed by tremor (26.5%, hallucinations (11.2%, and seizure (8.2%. Factors associated with neurological complications after OLT included preoperative dialysis, hepatorenal syndrome, renal insufficiency, intra-operative dialysis, preoperative encephalopathy, preoperative mechanical ventilation, and infection. Preoperative infection was an independent predictor of neurological complications (OR 2.83, 1.47 – 5.44. One-month mortality was 8.8% and was independently associated with urgent re-transplant, preoperative intubation, intraoperative arrhythmia, and intraoperative use of multiple pressors.Conclusion: Neurological complications are common in patients undergoing OLT in the post-MELD era, with encephalopathy being most frequent. An improved understanding of the risk factors related to both neurological complications and one-month mortality post-transplantation can better guide perioperative care and help improve outcomes among OLT patients.

    Full Text Available Summary Objective: Our study investigated type 2 diabetes mellitus (T2DM outpatients attending a university hospital in Montes Claros, MG, to estimate the prevalence of risk factors and their association with diabetes complications. Method: This was a quantitative, documental, retrospective and analytical study. Medical records of 95 outpatients with T2DM treated in this hospital from 2011 to 2015 were analyzed. Data were collected according to a structured questionnaire surveying sociodemographic, anthropometric and biochemical data and clinical and lifestyle aspects. Regression analysis was used to evaluate the association between risk factor variables and complications. Results: With a mean age of 54 years, the study population showed irregular blood glucose control, despite the use of hypoglycemic medication, and did not have a healthy lifestyle. The main complication reported was high blood pressure (HBP, occurring in 70.9% of patients. The prevalence of complications was positively associated with patients receiving insulin treatment (p=0.042 and multidisciplinary monitoring (p=0.050. Conclusion: The associations identified reflect the condition of patients that were already treating diabetes and its complications, especially HBP. The characteristics of the study population indicate the need to improve clinical follow-up and increase motivation for healthy behaviors.

    There seemed to be characteristic risk factors in cirrhotic patients for posthepatectomy complications because these patients have less hepatic reserve as compared with noncirrhotic patients. The aim of the current study was to identify these characteristic risk factors in cirrhotic patients. We performed 419 primary hepatectomies for hepatocellular carcinoma. The patients were divided into the cirrhotic group (n = 198) and the noncirrhotic group (n = 221), and the risk factors for posthepatectomy complications were compared between the groups. Thirty-six cirrhotic patients (18.2%) experienced Clavien's Grade III or more complications. Tumor size, intraoperative blood loss, duration of operation, major hepatectomy (two or more segments), and necessity of blood transfusion were found to be significant risk factors in univariate analyses. Multivariate analysis revealed that major hepatectomy and intraoperative blood loss were independent risk factors for posthepatectomy complications in patients with cirrhosis. On the other hand, the duration of operation was only an independent risk factor for posthepatectomy complication in noncirrhotic patients. Cirrhotic patients should avoid a major hepatectomy and undergo a limited resection preserving as much liver tissue as possible and meticulous surgical procedures to lessen intraoperative blood loss are mandatory to prevent major posthepatectomy complications.

    Although thoracentesis is generally considered safe, procedural complications are associated with increased morbidity, mortality, and healthcare costs. In this article, we review the risk factors and prevention of the most common complications of thoracentesis including pneumothorax, bleeding (chest wall hematoma and hemothorax), and re-expansion pulmonary edema. Recent data support the importance of operator expertise and the use of ultrasound in reducing the risk of iatrogenic pneumothorax. Although coagulopathy or thrombocytopenia and the use of anticoagulant or antiplatelet medications have traditionally been viewed as contraindications to thoracentesis, new evidence suggests that patients may be able to safely undergo thoracentesis without treating their bleeding risk. Re-expansion pulmonary edema, a rare complication of thoracentesis, is felt to result in part from the generation of excessively negative pleural pressure. When and how to monitor changes in pleural pressure during thoracentesis remains a focus of ongoing study. Major complications of thoracentesis are uncommon. Clinician awareness of risk factors for procedural complications and familiarity with strategies that improve outcomes are essential components for safely performing thoracentesis.

    Full Text Available Background Although the utility of flaps for the treatment of sternal wound infections following median sternotomy has been reported for 30 years, there have been few reports on the risk factors for complications after reconstruction. The objective of this investigation was to identify factors related to complications after the reconstruction of sternal wound infections. Methods A retrospective analysis of 74 patients with reconstructive surgery after sternal wound infection over a 5-year period was performed. Clinical data including age, sex, body mass index (BMI, comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected. Results The patients' BMI ranged from 15.2 to 33.6 kg/m2 (mean, 23.1±3.74 kg/m2. Wound closure complications after reconstructive surgery were observed in 36.5% of the cases. The mortality rate was 2.7%. Diabetes mellitus significantly affected the rate of wound closure complications (P=0.041. A significant difference in the number of complications was seen between Staphylococcus aureus (S. aureus and coagulase-negative Staphylococci (P=0.011. There was a correlation between harvesting of the internal thoracic artery and postoperative complications (P=0.048. The complication rates of the pectoralis major flap, rectus abdominis flap, omentum flap, a combination of pectoralis major flap and rectus abdominis flap, and direct closure were 23.3%, 33.3%, 100%, 37.5%, and 35.7%, respectively. Conclusions Diabetes mellitus, S. aureus, harvesting of the internal thoracic artery, and omentum flap were significant factors for complications after reconstruction. The omentum flap volume may be related to the complications associated with the omentum flap transfer in the present study.

    Retrospective cohort. Determine whether surgeon demographic factors influence postoperative complication rates after elective spine fusion procedures. Surgeon demographic factors have been shown to impact decision making in the management of degenerative disease of the lumbar spine. Complication rates are frequently reported outcome measurements used to evaluate surgical treatments, quality-of-care, and determine health care reimbursements. However, there are few studies investigating the association between surgeon demographic factors and complication outcomes after elective spine fusions. A database of US spine surgeons with corresponding postoperative complications data after elective spine fusions was compiled utilizing public data provided by the Centers for Medicare and Medicaid Services (2011-2013) and ProPublica Surgeon Scorecard (2009-2013). Demographic data for each surgeon was collected and consisted of: surgical specialty (orthopedic vs. neurosurgery), years in practice, practice setting (private vs. academic), type of medical degree (MD vs. DO), medical school location (United States vs. foreign), sex, and geographic region of practice. General linear mixed models using a Beta distribution with a logit link and pairwise comparison with post hoc Tukey-Kramer were used to assess the relationship between surgeon demographics and complication rates. 2110 US-practicing spine surgeons who performed spine fusions on 125,787 Medicare patients from 2011 to 2013 met inclusion criteria for this study. None of the surgeon demographic factors analyzed were found to significantly affect overall complication rates in lumbar (posterior approach) or cervical spine fusion. Publicly available complication rates for individual spine surgeons are being utilized by hospital systems and patients to assess aptitude and gauge expectations. The increasing demand for transparency will likely lead to emphasis of these statistics to improve outcomes. We conclude that none of the

    The number of men undergoing cosmetic surgery is increasing in North America. To determine the incidence and risk factors of major complications in males undergoing cosmetic surgery, compare the complication profiles between men and women, and identify specific procedures that are associated with higher risk of complications in males. A prospective cohort of patients undergoing cosmetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Gender specific procedures were excluded. Primary outcome was occurrence of a major complication in males requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis evaluated potential risk factors for major complications including age, body mass index (BMI), smoking, diabetes, type of surgical facility, type of procedure, and combined procedures. Of the 129,007 patients, 54,927 underwent gender nonspecific procedures, of which 5801 (10.6%) were males. Women showed a higher mean age (46.4 ± 14.1 vs 45.2 ± 16.7 years, P procedures (RR 3.47), and combined procedures (RR 2.56). Aesthetic surgery in men is safe with low major complication rates. Modifiable predictors of complications included BMI and combined procedures.

    Full Text Available Background and objectives: Currently, endoscopic medicine is being increasingly used, albeit not without risks. Therefore, this study evaluated the factors associated with perioperative complications in endoscopic surgery with intraoperative irrigation. Method: A cohort study of six months duration. Patients aged ≥ 18 years undergoing endoscopic surgery with the use of irrigation fluids during the intraoperative period were included. Exclusion criteria were: use of diuretics, kidney failure, cognitive impairment, hyponatremia prior to surgery, pregnancy, and critically ill. The patients who presented with or without complications during the perioperative period were allocated into two groups. Complications evaluated were related to neurological, cardiovascular and renal changes, and perioperative bleeding. Results: In total, 181 patients were enrolled and 39 excluded; therefore, 142 patients met the study criteria. Patients with complications amounted to 21.8%, with higher prevalence in endoscopic prostate surgery, followed by hysteroscopy, bladder, knee, and shoulder arthroscopy (58.1%, 36.9%, 19.4%, 3.8%, 3.2% respectively. When comparing both groups, we found association with complications in univariate analysis: age, sex, smoking, heart disease, ASA, serum sodium at the end of surgery, total irrigation fluid administered, TURP, and hysteroscopy. However, in multiple regression analysis for complications, only age (OR = 1.048, serum sodium (OR = 0.962, and volume of irrigation fluid administered during surgery (OR = 1.001 were independent variables.

    To Analyze the influence factors on the complications of percutaneous dilational tracheotomy. Between August 2008 and February 2014, there were 3 450 patients with the indications of tracheotomy accepted percutaneous dilational tracheostomy, mainly using percutaneous dilational and percutaneous guide wire forceps in these cases. Statistical analysis was performed by SPSS 19.0 software on postoperative complications, the possible influence factors including age, gender, etiology, preoperative hypoxia, obesity, preoperative pulmonary infection, state of consciousness, operation method, operation doctor and whether with tracheal intubation. Among 3 450 patients, there were 164 cases with intraoperative or postoperative complications, including postoperative bleeding in 74 cases (2.14%), subcutaneous emphysema in 54 cases (1.57%), wound infection in 16 cases (0.46%), pneumothorax in 6 cases (0.17%), mediastinal emphysema in 5 cases (0.14%), operation failed and change to conventional incision in 4 cases (0.12%), tracheoesophageal fistula in 2 cases (0.06%), death in 3 cases(0.09%).Obesity, etiology, preoperative hypoxia, preoperative pulmonary infection, state of consciousness and operation method were the main influence factors, with significant statistical difference (χ(2) value was 0.010, 0.000, 0.002, 0.000, 0.000, 0.000, all P Gender, age, operation doctor and whether there was the endotracheal intubation were not the main influence factors. There was no significant statistical difference (P > 0.05). Although percutaneous dilational tracheostomy is safe, but the complications can also happen. In order to reduce the complications, it is need to pay attention to the factors of obesity, etiology, preoperative hypoxia, preoperative pulmonary infection, state of consciousness and operation method.

    Complications of ostomy significantly affect the quality of life of ostomates. There is little evidence on the rate of long-term complications in ostomates, especially from the developing countries which include Sri Lanka. This study was aimed to describe the long-term complications of enteral ostomies and their contributory factors. A retrospective analysis was carried out on 192 patients who underwent ostomy creation over a period of 5 years. Data on type of complications, age, sex, type of ostomy, type of surgery and perioperative care by enteric stoma therapist were gathered. Associations were established using Chi square test and multiple logistic regression. Out of 192 patients, only 146 patients presented regularly for follow up. The mean follow up duration was 28 months (range: 3-183). Around 34.2% developed surgical long-term complications related to the ostomy. Common complications were prolapse (n = 24, 16.4%), skin excoriation (n = 22, 15.1%) and parastomal hernia (n = 14, 9.6%). Overall complication rate was significantly less in loop ostomies (p ostomies (p ostomies (p < 0.05). Perioperative care by enteric stoma therapist reduced the overall and specific complications (p < 0.001). The overall complication rate in our cohort of patients was 34.2%. The perioperative care of a stoma therapist may be very effective in preventing complications particularly in a setting with limited resources.

    Purpose: To systematically analyze risk factors for complications of in-bore transrectal MRI-guided prostate biopsies (MRGB). Materials and methods: 90 patients, who were scheduled for MRGB were included for this study. Exclusion criteria were coagulation disorders, therapy with anticoagulant drugs, and acute infections of the urinary and the lower gastrointestinal tract. Directly after, one week and one year after the biopsy, we assessed biopsy related complications (e.g. hemorrhages or signs of prostatitis). Differences between patients with and without complications were analyzed regarding possible risk factors: age, prostate volume, number of taken samples, biopsy duration, biopsy of more than one lesion, diabetes, arterial hypertension, hemorrhoids, benign prostate hyperplasia, carcinoma or prostatitis (according to histopathological analysis), and lesion localization. Complications were classified according to the Clavien-Dindo classification. Results: We observed 15 grade I complications in 90 biopsies (16.7%) with slight hematuria in 9 cases (10%), minor vasovagal reactions in 4 cases (4.4%), and urinary retention and positioning-related facial dysesthesia in 1 case each (1.1%). One patient showed acute prostatitis requiring antibiotics as the only grade II complication (1.1%). There were no adverse events that occurred later than one week. Complications grade III or higher such as pelvic abscesses, urosepsis or severe hemorrhages were not seen. There were no significant associations between the assessed risk factors and biopsy-related complications. Conclusion: In-bore transrectal MRI-guided prostate biopsies can be considered safe procedures in the diagnosis of prostate cancer with very low complication rates. There seem to be no risk factors for complications.

    Smoking induces complications in plastic surgery, in particular wound healing delays. Despite a 4-weeks' abstinence asking before and after surgery, some patients denied or hid their consumption. The aim of this study was to evaluate the effectiveness of a cotininury detection test in terms of improvement in outcomes after an abdominoplasty. This retrospective cohort study included patients who underwent an abdominoplasty with umbilical transposition and lipoaspiration. Current smokers were asked to stop smoking 4 weeks before and after surgery. After 2013, we performed a preoperative cotininury test for patients having abdominoplasty, with a cancellation of surgery in case of positive result. We analyzed the test's effectiveness on delayed healing and on other complications. Two hundred and thirty-five patients were included; 80 were tested and 21,3% had a positive test. There was significantly less delayed healing in the "screening" group than in the "no screening": 20,3% versus 41,5% (P=0,002). Alike, complications were significantly less frequent in the "screening" group than in the "no screening": 18,1% versus 42,3% (P<0,001). The routine use of the cotininury test in preoperative abdominoplasties significantly reduces risk of delayed healing and other serious complications. It is an objective test, which is simple, quick and non-invasive. Smoking cessation must be at least 4 weeks before and after the surgery. Following medical advice to cease smoking by the surgeon and anesthetist, referral to an appropriate tobacco-addiction specialist clinic may be helpful for the patient who has difficulty stopping smoking.

    Among aesthetic surgery procedures, abdominoplasty is associated with a higher complication rate, but previous studies are limited by small sample sizes or single-institution experience. A cohort of patients who underwent abdominoplasty between 2008 and 2013 was identified from the CosmetAssure database. Major complications were recorded. Univariate and multivariate analysis was performed evaluating risk factors, including age, smoking, body mass index, sex, diabetes, type of surgical facility, and combined procedures. The authors identified 25,478 abdominoplasties from 183,914 procedures in the database. Of these, 8,975 patients had abdominoplasty alone and 16,503 underwent additional procedures. The number of complications recorded was 1,012 (4.0 percent overall rate versus 1.4 percent in other aesthetic surgery procedures). Of these, 31.5 percent were hematomas, 27.2 percent were infections and 20.2 percent were suspected or confirmed venous thromboembolism. On multivariate analysis, significant risk factors (p procedures (1.5), and procedure performance in a hospital or surgical center versus office-based surgical suite (1.6). Combined procedures increased the risk of complication (abdominoplasty alone, 3.1 percent; with liposuction, 3.8 percent; breast procedure, 4.3 percent; liposuction and breast procedure, 4.6 percent; body-contouring procedure, 6.8 percent; liposuction and body-contouring procedure, 10.4 percent). Abdominoplasty is associated with a higher complication rate compared with other aesthetic procedures. Combined procedures can significantly increase complication rates and should be considered carefully in higher risk patients. Risk, II.

    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.

    Percutaneous nephrolithotomy (PNL) is a minimally invasive procedure used for successful treatment of renal calculi. However, it is associated with various complications. We assessed the complications and their potential influencing factors in patients who had undergone PNL. In total, 1750 patients who had undergone PNL from November 2003 to June 2011 were evaluated retrospectively. PNL complications and possible contributing risk factors (age, sex, serum creatinine level, previous operations, hydronephrosis, calculi size, localization, opacity, surgeon's experience, accessed calyxes, number of accesses, and costal entries) were determined. Receiver operating characteristic (ROC) analysis was used to investigate the cutoff values of the data. Ideal cutoff value was determined by Youden's J statistic. All the demographic and clinical variables were examined using backward stepwise logistical regression analysis. Continuous variables were categorized with logistic regression analysis according to the cutoff values. Complications occurred in 396 (24.4%) patients who had undergone PNL. Hemorrhage requiring blood transfusion occurred in 221 (12.6%) patients, hemorrhage requiring arterial embolization occurred in 7 (0.4%) patients, perirenal hematoma occurred in 17 (0.97%) patients, hemo-pneumothorax occurred in 32 (1.8%) patients, and colon perforation occurred in 4 (0.22%) patients. Three patients (0.06%) died of severe urosepsis, and one patient (0.02%) died of severe bleeding. The calculus size, localization, access site, number of accesses, presence of staghorn stones, surgeon's experience, and duration of the operation significantly affected the complication risk. Our retrospective evaluation of this large patient series reveals that, PNL is a very effective treatment modality for kidney stones. However, although rare, serious complications including death can occur.

    High complication rates have been cited following olfactory groove meningioma (OGM) resection but data are lacking on attendant risk factors. We aimed to review the complications following OGM resection and identify prognostic factors. A retrospective review was performed on 34 consecutive patients who underwent primary OGM resection at a single London institution between March 2008 and February 2013. Collected data included patient comorbidities, pre-operative corticosteroid use, tumour characteristics, imaging features, operative details, extent of resection, histology, use of elective post-operative ventilation, complications, recurrence and mortality. Complication rate was 39%. 58% of complications required intensive care or re-operation. Higher complication rates occurred with OGM > 40 mm diameter versus ≤ 40 mm (53 vs. 28%; p = 0.16); OGM with versus without severe perilesional oedema (59 vs. 19%; p = 0.26), more evident when corrected for tumour size; and patients receiving 1-2 days versus 3-5 days of pre-operative dexamethasone (75 vs. 19%; p = 0.016). Patients who were electively ventilated post-operatively versus those who were not had higher risk tumours but a lower complication rate (17 vs. 44%; p = 0.36) and a higher proportion making a good recovery (83 vs. 55%; p = 0.20). Complete versus incomplete resection had a higher complication rate (50 vs. 23%; p = 0.16) but no recurrence (0 vs. 25%; p = 0.07). Risk of morbidity with OGM resection is high. Higher complication risk is associated with larger tumours and greater perilesional oedema. Pre-operative dexamethasone for 3-5 days versus shorter periods may reduce the risk of complications. We describe a characteristic pattern of perilesional oedema termed 'sabre-tooth' sign, whose presence is associated with a higher complication rate and may represent an important radiological prognostic sign. Elective post-operative ventilation for patients with high-risk tumours may reduce the risk of complications.

    Paitients and methods: We retrospectively reviewed a database of 188 patients who underwent resection for colorectal cancer with laparoscopic surgery between July 2007 and March 2015. The prognostic nutrition index(PNI), modified Glas- gow prognostic score(mGPS), controlling nutritional status(CONUT), and neutrophil/lymphocyte ratio(N/L)were measured in these patients. We examined the association between postoperative complications and clinicopathological factors. The study included 110 men and 78 women. Median age was 68 years. The site of the primary lesion was colon in 118 and rectum in 70 patients. Postoperative complications higher than Grade II(Clavien-Dindo classification)were reported in 24(12.8%)patients: Surgical site infection(SSI)in 12, remote infection in 7, ileus in 5, and others in 2 patients. Clinicopathological factors related to complications were rectal surgery, large amount of intraoperative bleeding, and long operative time. The related immunologic and nutritional factors were mGPS 2, PNI below 40, and N/L above 3. CONUT was not associated with complications in ourcases. mGPS, PNI, and N/L are predictive factors for complications in laparoscopic colorectal surgery.

    Purpose/Objective: To determine the incidence of late rectal complications in patients treated with high dose rate brachytherapy for FIGO stage IIB, IIIB carcinoma of the uterine cervix, and to evaluate the treatment factors associated with an increased probability of treatment complications. Materials and Methods: Records of 100 patients with FIGO IIB or IIIB cervical carcinoma treated with definitive irradiation using high dose rate intracavitary brachytherapy (HDR-ICR) between 1977 and 1994 were retrospectively reviewed. For each HDR-ICR session, 6 Gy isodose volume was reconstructed three dimensionally and the following three parameters were determined to represent this isodose volume, length (L); maximum longitudinal distance of 6 Gy isodose area in an oblique frontal plane containing the intrauterine applicator, width (W); maximum width of 6 Gy isodose area in the same plane, height (H); maximum dimension of 6 Gy isodose area perpendicular to the intrauterine applicator determined in the oblique sagittal plane. Point P/Q (2 cm ventral/dorsal from the proximal retention point of the intrauterine source) and point R/S (2 cm ventral/dorsal from the midpoint of the ovoid sources) were also defined retrospectively and HDR-ICR dose at these points were calculated. Statistical analyses were performed to determine the treatment factors predictive of late rectal complications. Results: The 5-year cumulative cause-specific disease-free survival rate was 50% for all, 74% for Stage IIB, and 38% for Stage IIIB, with a significant difference between two FIGO Stages (p=0.0004). Of patients treated for both stages, 30% and 36% had experienced moderate to severe (Grade 2-4) complications at 3 and 5 years, respectively. Average H value (p=0.013) and cumulative point S dose by HDR-ICR (p=0.020) were significantly correlated with the incidence of late rectal complications (Student's t-test), whereas these factors did not significantly affect the probability of pelvic control.

    The purpose of this study is to estimate the overall frequency of complications associated with third molars (M3) removal and to identify the risk factors associated with these complications. To the transversal analysis, a researcher confidentially reviewed the records of all M3 surgery patients. The predictor variables were demographic (i.e. age and gender), localization and position of third molar, bone removal and tooth sectioning. 210 patients had one or more third molars teeth removed, a total of 605 teeth. The sample's mean age was 21.6±9.2 years, with 1,4 woman to 1 man. Postoperative complications were recorded in 54 extractions of third molars. The most common complications were infection (42.6%), followed by radicular fractures (11.1%) and gingival alterations (11.1%). Complications were significantly affected by 3 factors: age over 25 years old (p=0.002--OR 2.21), location (p=0.006--OR 2.36), bone removal (p=0.002--OR 3.03) and tooth sectioning (p=0.00002--OR 3.59). The results of these analyses suggest that age, location of the tooth, bone removal and tooth sectioning appear to be associated with a higher complication rate for M3 extractions.

    Age has been classically considered as a determining factor for the development of postoperative complications related to lung resection for bronchogenic carcinoma. The Postoperative Complications Study Group of the Spanish Society of Thoracic Surgery has promoted a registry to analyze this factor. A total of 3,307 patients who underwent any type of surgical resection for bronchogenic carcinoma have been systematically and prospectively recorded in any of the 24 units that are part of the group. Several variables related to comorbidity and age, as well as postoperative complications, were analyzed. The mean age of patients was 65,44. Men were significantly more common than female. The most frequent complication was prolonged air leak, which was observed in more than one third of patients. In a univariant analysis, air leak presence and postsurgical atelectasis showed statistical association with patient age, when stratified in age groups. In a multivariate analysis, age was recognized as an independent prognostic factor in relation to air leak onset. However, this could not be confirmed for postoperative atelectasis. Age is a predisposing factor for the development of postoperative complications after lung resection. Other associated factors also influence the occurrence of these complications.

    Objective. To explore risk factors for macro- and microvascular complications in a nationally representative sample of adults aged 50 years and over with type 2 diabetes in Ireland. Methods. Data from the first wave of The Irish Longitudinal Study on Ageing (TILDA) (2009-2011) was used in cross-sectional analysis. The presence of doctor diagnosis of diabetes, risk factors, and macro- and microvascular complications were determined by self-report. Gender-specific differences in risk factor prevalence were assessed with the chi-squared test. Binomial regression analysis was conducted to explore independent associations between established risk factors and diabetes-related complications. Results. Among 8175 respondents, 655 were classified as having type 2 diabetes. Older age, being male, a history of smoking, a lower level of physical activity, and a diagnosis of high cholesterol were independent predictors of macrovascular complications. Diabetes diagnosis of 10 or more years, a history of smoking, and a diagnosis of hypertension were associated with an increased risk of microvascular complications. Older age, third-level education, and a high level of physical activity were protective factors (p < 0.05). Conclusions. Early intervention to target modifiable risk factors is urgently needed to reduce diabetes-related morbidity in the older population in Ireland.

    Full Text Available The systemic complications of blood donation are the first reasons why patients fail to return for further blood donation. This study was designed to determine the frequency of these complications and their associated risk factors among blood donors in Tehran. Also, we aimed to provide suitable methods to decrease the frequency of these adverse events, thereby eliminating the most important causes of withdrawal, while maintaining the health of the donors. This analytical descriptive cross-sectional study was performed on 554 blood donors who had donated blood from February 2005 through September 2005 in four fixed blood donation bases and four mobile blood collection buses. Each base was considered as a stratum, and a stratified random sampling proportional to size was done to select the donors. Results showed donor reaction rate to be 13.4%, the most common of which were blackout of vision (7%, dizziness (6.3%, fatigue (6.1% and nausea (1.8%. There was no significant relationship between the incidence of these complications and type of base blood donation or fasting at the time of blood donation. Logistic Regression analysis showed that sex, condition of blood donor, exercise or walking, duration of donation, and practice to recommendation had significant effects on the odds ratio of systemic complication. Regarding the frequency values derived for the different systemic complications it can be concluded that attention to risk factors of these complications and their control can help encourage donors to become repeated donors as well as to prevent their withdrawal for further blood donation.

    Purpose: To assess the association of clinical and especially dosimetric factors with the incidence of postoperative pulmonary complications among esophageal cancer patients treated with concurrent chemoradiation therapy followed by surgery. Method and Materials: Data from 110 esophageal cancer patients treated between January 1998 and December 2003 were analyzed retrospectively. All patients received concurrent chemoradiotherapy followed by surgery; 72 patients also received irinotecan-based induction chemotherapy. Concurrent chemotherapy was 5-fluorouracil-based and in 97 cases included taxanes. Radiotherapy was delivered to a total dose of 41.4-50.4 Gy at 1.8-2.0 Gy per fraction with a three-dimensional conformal technique. Surgery (three-field, Ivor-Lewis, or transhiatal esophagectomy) was performed 27-123 days (median, 45 days) after completion of radiotherapy. The following dosimetric parameters were generated from the dose-volume histogram (DVH) for total lung: lung volume, mean dose to lung, relative and absolute volumes of lung receiving more than a threshold dose (relative V dose and absolute V dose ), and absolute volume of lung receiving less than a threshold dose (volume spared, or VS dose ). Occurrence of postoperative pulmonary complications, defined as pneumonia or acute respiratory distress syndrome (ARDS) within 30 days after surgery, was the endpoint for all analyses. Fisher's exact test was used to investigate the relationship between categorical factors and incidence of postoperative pulmonary complications. Logistic analysis was used to analyze the relationship between continuous factors (e.g., V dose or VS dose ) and complication rate. Logistic regression with forward stepwise inclusion of factors was used to perform multivariate analysis of those factors having univariate significance (p < 0.05). The Mann-Whitney test was used to compare length of hospital stay in patients with and without lung complications and to compare lung volumes, VS5

    The surgical treatment for perforated peptic ulcers can be safely performed laparoscopically. The aim of the study was to define simple predictive factors for conversion and septic complications. This retrospective case-control study analyzed patients treated with either laparoscopic surgery or laparotomy for perforated peptic ulcers. A total of 71 patients were analyzed. Laparoscopically operated patients had a shorter hospital stay (13.7 vs. 15.1 days). In an intention-to-treat analysis, patients with conversion to open surgery (analyzed as subgroup from laparoscopic approach group) showed no prolonged hospital stay (15.3 days) compared to patients with a primary open approach. Complication and mortality rates were not different between the groups. The statistical analysis identified four intraoperative risk factors for conversion: Mannheim peritonitis index (MPI) > 21 (p = 0.02), generalized peritonitis (p = 0.04), adhesions, and perforations located in a region other than the duodenal anterior wall. We found seven predictive factors for septic complications: age >70 (p = 0.02), cardiopulmonary disease (p = 0.04), ASA > 3 (p = 0.002), CRP > 100 (p = 0.005), duration of symptoms >24 h (p = 0.02), MPI > 21(p = 0.008), and generalized peritonitis (p = 0.02). Our data suggest that a primary laparoscopic approach has no disadvantages. Factors necessitating conversions emerged during the procedure inhibiting a preoperative selection. Factors suggesting imminent septic complications can be assessed preoperatively. An assessment of the proposed parameters may help optimize the management of possible septic complications.

    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.

    Objective: To retrospectively evaluate the cerebrovascular complications from stenting for symptomatic intracranial stenosis and to detect the factors associated with complications. Methods: Medical records of Wingspan stenting were reviewed for 306 cases with symptomatic intracranial stenosis from July 2007 to February 2012, including transient ischemic attack, ischemic stroke, death and intracranial hemorrhage as clinical in-hospital complications. The location of lesions included middle cerebral artery level M1 (114 lesions), intracranial portion of the internal carotid artery (50 lesions), vertebral artery 4 (75 lesions), venebro-basilar artery (14 lesions), basilar artery (76 lesions). Complications were evaluated and analyzed to find out whether they were associated with patient-or stenosis-related risk factors using χ"2 test. Results: The technical success rate was 99% (303/306). Cerebrovascular complications rate was 6.9% (21/303), with 1.6% (14/303) of disabling stroke events and 0.7% (2/303) of deaths. Hemorrhagic events were consisted of procedure-related events (3 cases), hyperperfusion (3 cases), ischemic events of perforator stroke (8 cases), transient ischemic attack (3 cases), embolization (2 cases), thrombosis in stent (2 cases). Hemorrhagic events were associated with significantly higher morbidity and mortality rates (χ"2 = 2.908, P < 0.05) and occurred more frequently after treatment of middle cerebral artery stenosis than other lesions (χ"2 = 1.168, P < 0.05). Perforating branches were detected to be affected mainly in the basilar artery than other locations (χ"2 = 4.263, P < 0.05). Conclusion: The complication rates in the study are preliminary consistent with the previously published data. Hemorrhagic events are prone to occur in the treatment of middle cerebral artery stenosis, while perforating branches are affected mainly in the basilar artery. (authors)

    Purpose: While trimodality therapy for esophageal cancer has improved patient outcomes, surgical complication rates remain high. The goal of this study was to identify modifiable factors associated with postoperative complications after neoadjuvant chemoradiation. Methods and Materials: From 1998 to 2011, 444 patients were treated at our institution with surgical resection after chemoradiation. Postoperative (pulmonary, gastrointestinal [GI], cardiac, wound healing) complications were recorded up to 30 days postoperatively. Kruskal-Wallis tests and χ 2 or Fisher exact tests were used to assess associations between continuous and categorical variables. Multivariate logistic regression tested the association between perioperative complications and patient or treatment factors that were significant on univariate analysis. Results: The most frequent postoperative complications after trimodality therapy were pulmonary (25%) and GI (23%). Lung capacity and the type of radiation modality used were independent predictors of pulmonary and GI complications. After adjusting for confounding factors, pulmonary and GI complications were increased in patients treated with 3-dimensional conformal radiation therapy (3D-CRT) versus intensity modulated radiation therapy (IMRT; odds ratio [OR], 2.018; 95% confidence interval [CI], 1.104-3.688; OR, 1.704; 95% CI, 1.03-2.82, respectively) and for patients treated with 3D-CRT versus proton beam therapy (PBT; OR, 3.154; 95% CI, 1.365-7.289; OR, 1.55; 95% CI, 0.78-3.08, respectively). Mean lung radiation dose (MLD) was strongly associated with pulmonary complications, and the differences in toxicities seen for the radiation modalities could be fully accounted for by the MLD delivered by each of the modalities. Conclusions: The radiation modality used can be a strong mitigating factor of postoperative complications after neoadjuvant chemoradiation

    Prior research has provided inconsistent data regarding the risk factors associated with complications from arterial cannulation. The goal of this study was to clearly define the incidence and risks factors associated with arterial cannulation complications. After obtaining institutional review board approval, all patients requiring arterial line placement with documentation were included in this retrospective study between January 1, 2006, and December 31, 2012. Leveraging two robust data warehouses, the Perioperative DataMart and the Mayo Clinic Life Silences System, the authors cross-matched arterial line cannulation with a documented vascular consult, neurologic consult, infection, or return to surgery within 30 days in order to identify the initial patient population. A total of 62,626 arterial lines were placed in 57,787 patients, and 90.1% of the catheters placed were 20-gauge catheters. The radial artery was cannulated in 94.5% of patients. A total of 21 patients were identified as having experienced vascular complications or nerve injuries, resulting in a complication rate of 3.4 per 10,000 (95% CI, 2.1 to 5.1). Cardiac surgery had the largest number of catheters placed (n = 15,419) with 12 complications (complication rate = 7.8 per 10,000; 95% CI, 4.0 to 13.6). The rate of complications differed significantly (P < 0.001) across the three most common catheter sizes (2.7 per 10,000 [95% CI, 1.5 to 4.4] for 20 gauge, 17.2 per 10,000 [95% CI, 4.7 to 43.9] for 18 gauge, and 9.4 per 10,000 [95% CI, 1.1 to 34.1] for 5 French). In a large retrospective study, the authors document a very low rate of complications with arterial line placement.

    Image-defined risk factors (IDRFs) have been propounded for predicting the surgical risks associated with localized neuroblastoma (NB) since 2009. In 2011, a new guideline (NG) for assessing IDRFs was published. According to the NG, the situation in which "the tumor is only in contact with renal vessels," should be considered to be "IDRF-present." Previously, this situation was diagnosed as "IDRF absent." In this study, we evaluated the IDRFs in localized NB patients to clarify the predictive capability of IDRFs for surgical complications, as well as the usefulness of the NG. Materials and A total of 107 localized patients with NB were included in this study. The enhanced computed tomography and magnetic resonance images from the time of their diagnoses were evaluated by a single radiologist. We also analyzed the association of clinical factors, including the IDRFs (before and after applying the NG), with surgical complications. Of the 107 patients, 33 and 74 patients were diagnosed as IDRF-present (OP group), and IDRF-absent (ON group) before the NG, respectively. According to the NG, there were 76 and 31 patients who were classified as IDRF-present (NP group) and IDRF absent (NN group), respectively. Thus, 43 (40%) patients in the ON group were reassigned to the NP group after the NG. Surgical complications were observed in 17 of 82 patients who underwent surgical resection. Of the patients who underwent secondary operations, surgical complication rates were 55% in the OP group and 44% in the NP group. According to a univariate analysis, non-INSS 1, IDRFs before and after the NG and secondary operations were significantly associated with surgical complications. In a multivariate analysis, non-INSS 1 status and IDRFs after the NG were significantly associated with surgical complications. Georg Thieme Verlag KG Stuttgart · New York.

    The objective of this study was to describe the incidence of complications in children with esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) at a tertiary pediatric hospital and to identify predictive factors for their occurrence. A retrospective chart review of 110 patients born in or transferred to Sydney Children's Hospital with EA/TEF between January 1999 and December 2010 was done. Univariate and multivariate regression analyses were performed to identify predictive factors for the occurrence of complications in these children. From univariate analysis, early esophageal stricture formation was more likely in children with 'long-gap' EA (odds ratio [OR] = 16.32). Patients with early strictures were more likely to develop chest infections (OR = 3.33). Patients with severe tracheomalacia were more likely to experience 'cyanotic/dying' (OR = 180) and undergo aortopexy (OR = 549). Patients who had gastroesophageal reflux disease were significantly more likely to require fundoplication (OR = 10.83) and undergo aortopexy (OR = 6.417). From multivariate analysis, 'long-gap' EA was a significant predictive factor for late esophageal stricture formation (P = 0.007) and for gastrostomy insertion (P = 0.001). Reflux was a significant predictive factor for requiring fundoplication (P = 0.007) and gastrostomy (P = 0.002). Gastrostomy insertion (P = 0.000) was a significant predictive factor for undergoing fundoplication. Having a prior fundoplication (P = 0.001) was a significant predictive factor for undergoing a subsequent aortopexy. Predictive factors for the occurrence of complications post EA/TEF repair were identified in this large single centre pediatric study. © 2014 International Society for Diseases of the Esophagus.

  11. Risk factors for recurrence, complications and mortality in Clostridium difficile infection: a systematic review.

    Claire Nour Abou Chakra

    Full Text Available BACKGROUND: Clostridium difficile infection (CDI can lead to complications, recurrence, and death. Numerous studies have assessed risk factors for these unfavourable outcomes, but systematic reviews or meta-analyses published so far were limited in scope or in quality. METHODS: A systematic review was completed according to PRISMA guidelines. An electronic search in five databases was performed. Studies published until October 2013 were included if risk factors for at least one CDI outcome were assessed with multivariate analyses. RESULTS: 68 studies were included: 24 assessed risk factors for recurrence, 18 for complicated CDI, 8 for treatment failure, and 30 for mortality. Most studies accounted for mortality in the definition of complicated CDI. Important variables were inconsistently reported, such as previous episodes and use of antibiotics. Substantial heterogeneity and methodological limitations were noted, mainly in the sample size, the definition of the outcomes and periods of follow-up, precluding a meta-analysis. Older age, use of antibiotics after diagnosis, use of proton pump inhibitors, and strain type were the most frequent risk factors for recurrence. Older age, leucocytosis, renal failure and co-morbidities were frequent risk factors for complicated CDI. When considered alone, mortality was associated with age, co-morbidities, hypo-albuminemia, leucocytosis, acute renal failure, and infection with ribotype 027. CONCLUSION: Laboratory parameters currently used in European and American guidelines to define patients at risk of a complicated CDI are adequate. Strategies for the management of CDI should be tailored according to the age of the patient, biological markers of severity, and underlying co-morbidities.

    To determine factors affecting the stone-free rate and complications of percutaneous nephrolithotomy (PNL) for treatment of staghorn stones. The computerized database of patients who underwent PNL for treatment of staghorn stones between January 2003 and January 2011 was reviewed. All perioperative complications were recorded and classified according to modified Clavien classification system. The stone-free rate was evaluated with low-dose noncontrast computed tomography (CT). Univariate and multivariate statistical analyses were performed to determine factors affecting stone-free and complication rates. The study included 241 patients (125 male and 116 female) with a mean age of 48.7 ±14.3 years. All patients underwent 251 PNL (10 patients had bilateral stones). The stone-free rate of PNL monotherapy was 56% (142 procedures). At 3 months, the stone-free rate increased to 73% (183 kidneys) after shock wave lithotripsy. Independent risk factors for residual stones were complete staghorn stone and presence of secondary calyceal stones (relative risks were 2.2 and 3.1, respectively). The complication rate was 27% (68 PNL). Independent risk factors for development of complications were performance of the procedure by urologists other than experienced endourologist and positive preoperative urine culture (relative risks were 2.2 and 2.1, respectively). Factors affecting the incidence of residual stones after PNL are complete staghorn stones and the presence of secondary calyceal stones. Complications are significantly high if PNL is not performed by an experienced endourologist or if preoperative urine culture is positive. Copyright © 2012 Elsevier Inc. All rights reserved.

    Objective: To investigate the frequency, patterns of the angiographic findings and risk factors for development of complications after transcatheter arterial chemoembolization (TACE) via the inferior phrenic artery (IPA). Methods: One hundred and sixty eight patients with hepatic tumor fed by the IPA underwent a total of 226 procedures of TACE of the IPA, with combined routine TACEO (88.7%) or without (11.3%) the combination of routine TACE of the hepatic artery. TACE of the malignancy was performed with an emulsion of iodized oil and anti-cancer agents and then followed by gelatin sponge particle injection. The complications were assessed on clinical observation, laboratory tests, and computed tomographic (CT) images after TACE of the IPA; and finally were correlated with the angiographic findings of the IPA. Results: The tumor supplied by IPA was noted at initial TACE in 25 (14.9%), at successive TACE in 97 (57.8%), after percutaneous tumor ablation guided by ultrasound in 28 (16.7%), and after hepatic surgery in 18 (10.7%) cases. The abnormal findings on arteriography showed enlargement of the IPA with tumor staining in all cases, dense non-tumor staining in 61 (36.3%), artery-to-artery anastomosis in 62(36.9%), arteriovenous shunts in 12(7.1%) cases. 96.4% of these patients complained of shoulder pain during TACE of the IPA. The cumulative complication rate after the procedure was 8.9%, including hiccup in 13 cases (5.8%), chest pain with cough and mild hemoptysis in 9 (4.0%), phrenoparalysis in 8 (3.5%), angina with abnormal ECG in 4 (1.8%), increasing of CPK, AST, and ALT significantly in 6 (2.7%), transient myeloparalysis in 2 (0.9%), and subphrenic abscess in 2 cases (0.9%). Two patients with the subphrenic abscess were successfully treated with percutaneous catheter drainage and antibiotics. The symptoms of these mild complications subsided with symptomatic treatment. Conclusions: Complications of TACE via the IPA occur in about 9% of the patients and

    Major complications following aesthetic breast surgery are uncommon and thus assessment of risk factors is challenging. To determine the incidence and risk factors of major complications following aesthetic breast surgery and concomitant procedures. A prospective cohort of patients who enrolled into the CosmetAssure (Birmingham, AL) insurance program and underwent aesthetic breast surgery between 2008 and 2013 was identified. Major complications (requiring reoperation, readmission, or emergency room visit) within 30 days of surgery were recorded. Risk factors including age, smoking, body mass index (BMI), diabetes, type of surgical facility, and combined procedures were evaluated. Among women, augmentation was the most common breast procedure (n = 41,651, 58.6%) followed by augmentation-mastopexy, mastopexy, and reduction. Overall, major complications occurred in 1.46% with hematoma (0.99%) and infection (0.25%) being most common. Augmentation-mastopexy had a higher risk of complications, particularly infection (relative risk [RR] 1.74, P procedures. Age was the only significant predictor for hematomas (RR 1.01, P procedures or abdominoplasty performed alone. Among men, correction of gynecomastia was the most common breast procedure (n = 1613, 64.6%) with a complication rate of 1.80% and smoking as a risk factor (RR 2.73, P = 0.03). Incidence of major complications after breast cosmetic surgical procedures is low. Risk factors for major complications include increasing age and BMI. Combining abdominoplasty with any breast procedure increases the risk of major complications. 2. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

    Full Text Available Abstract OBJECTIVE To evaluate the incidence of complications related to the use of peripheral intravenous catheter in neonates and identify the associated risk factors. METHOD Prospective cohort study conducted in a Neonatal Intensive Care Unit. Participants were the hospitalized neonates undergoing peripheral intravenous puncture in the period from February to June 2013. RESULTS The incidence of complications was 63.15%, being infiltration/extravasation (69.89%, phlebitis (17.84% and obstruction (12.27%. The risk factors were the presence of infection (p = 0.0192 and weight at the puncture day (p = 0.0093, type of intermittent infusion associated with continuous infusion (p <0.0001, endotracheal intubation (p = 0.0008, infusion of basic plan (p = 0.0027, total parenteral nutrition (P = 0.0002, blood transfusion associated with other infusions (p = 0.0003 and other drugs (p = 0.0004. Higher risk of developing complications in the first 48 hours after puncture. CONCLUSION A high rate of complications related to the use of peripheral intravenous catheter, and risk factors associated with infection, weight, drugs and infused solutions, and type of infusion.

    Full Text Available Foot complications are considered to be a serious consequence of diabetes mellitus, posing a major medical and economical threat. Identifying the extent of this problem and its risk factors will enable health providers to set up better prevention programs. Saudi National Diabetes Registry (SNDR, being a large database source, would be the best tool to evaluate this problem.This is a cross-sectional study of a cohort of 62,681 patients aged ≥ 25 years from SNDR database, selected for studying foot complications associated with diabetes and related risk factors.The overall prevalence of diabetic foot complications was 3.3% with 95% confidence interval (95% CI of (3.16%-3.44%, whilst the prevalences of foot ulcer, gangrene, and amputations were 2.05% (1.94%-2.16%, 0.19% (0.16%-0.22%, and 1.06% (0.98%-1.14%, respectively.

    Mechanical complications are of particular concern in urgent-start peritoneal dialysis (PD) because of the shorter break-in period. However, risk factors have been reported inconsistently and data in urgent-start PD populations are limited. Observational cohort study. All patients treated with urgent-start PD, defined as PD therapy initiated within 1 week after catheter insertion, January 2003 to May 2013. Age, sex, abdominal surgery history, body mass index, hemoglobin level, albumin level, C-reactive protein level, break-in period (period between catheter insertion and PD therapy initiation), dialysate exchange volume, and use of overnight dwell. The presence of mechanical complications related to abdominal wall or catheter, including hernia, hydrothorax, hydrocele, subcutaneous leak, pericatheter leak, catheter malposition, omental wrap, and obstruction. 922 patients on urgent-start PD therapy were enrolled (mean age, 59.1±15.0 [SD] years). Prevalences of abdominal wall and catheter complications were 4.8% and 9.5%, respectively. The most common abdominal wall complication was hernia (55%), followed by hydrothorax (25%). On adjustment, male sex (HR, 5.41; 95% CI, 2.15-13.59; Pstart PD and conventional PD. Urgent-start PD is a safe and practicable approach. Male sex and history of abdominal surgery could contribute to the development of abdominal wall complications. Copyright © 2017 National Kidney Foundation, Inc. Published by Elsevier Inc.

    Purpose: Further actuarial analyses of neurological complications were performed on a larger population treated by stereotactic radiosurgery at our institution, to establish the optimal treatment parameters. Methods and Materials: Between June 1990 and September 1998, 138 patients with acoustic neurinomas underwent stereotactic radiosurgery at Tokyo University Hospital. Of these, 125 patients who received medical follow-up for 6 months or more entered the present study. Patient ages ranged from 13 to 77 years (median, 53 years). Average tumor diameter ranged from 6.7 to 25.4 mm (mean, 13.9 mm). Maximum tumor doses ranged from 20 to 40 Gy (mean, 29.8 Gy) and peripheral doses from 12 to 25 Gy (mean, 15.4 Gy). One to 12 isocenters were used (median, 4). Follow-up period ranged from 6 to 104 months (median, 37 months). The potential risk factors for neurological complications were analyzed by two univariate and one multivariate actuarial analyses. Neurological complications examined include hearing loss, facial palsy, and trigeminal nerve dysfunction. Variables included in the analyses were four demographic variables, two variables concerning tumor dimensions, and four variables concerning treatment parameters. A variable with significant p values (p < 0.05) on all three actuarial analyses was considered a risk factor. Results: The variables that had significant correlation to increasing the risk for each neurological complication were: Neurofibromatosis Type 2 (NF2) for both total hearing loss and pure tone threshold (PTA) elevation; history of prior surgical resection, tumor size, and the peripheral tumor dose for facial palsy; and the peripheral tumor dose and gender (being female) for trigeminal neuropathy. In facial palsies caused by radiosurgery, discrepancy between the course of palsy and electrophysiological responses was noted. Conclusion: Risk factors for neurological complications seem to have been almost established, without large differences between

    The management of colon injuries has distinctly evolved over the last three decades. However, trauma surgeons often find themselves in a dilemma, whether to perform a diversion or to perform a primary repair. The purpose of this study is to evaluate risk factors in colon injury management and their influence on abdominal complications. This is a prospective study conducted at a national level I trauma center in Tirana, Albania from January 2009 to December 2012. The data with respect to demographics, physiological risk factors, intraoperative findings, and surgical procedures were collected. Colonic injury-related morbidity and mortality were analyzed. Multivariate logistic regression analysis was performed by assessing the influence of risk factors on abdominal complications. Of the 157 patients treated with colon injury, was performed a primary repair in 107 (68.15%) of the patients and a diversion in the remaining 50 (31.85%). The mean PATI was 18.6, while 37 (23.6%) of patients had PATI greater than 25. The complications and their frequencies according to the surgical technique used (primay repair vs diversion respectively) includes: wound infections (9.3% vs 50%), anastomotic leak (1.8% vs 8.7%), and intra-abdominal abscess (1.8% vs 6.5%). The multivariate analysis identified two independent risk factors for abdominal complications: transfusions of 4 units of blood within the first 24 hours (OR = 1.2 95% CI (1.03 - 1.57) p =0.02), and diversion (OR = 9.6, 95% CI 4.4 - 21.3, pcolon injuries are both independent risk factors for abdominal complications. The socioeconomic impact and the need for a subsequent operation in colostomy patients are strong reasons to consider primary repair in the management of colon injuries.

  1. Human and organisational factors in the reliability of non-destructive testing (NOT)

    Non-destructive testing used in in-service inspections can be seen as a complicated activity system including three mutually related sub-activities: (1) definition of inspection programs and necessary resources, (2) carrying out diagnostic inspections, and (3) interpretation of the results from the view of plant safety and corrective measures. Various studies to investigate and measure the NDT performance have produced disappointing result. No clear correlations between single human factors and performance have been identified even though general agreement exists concerning the significance of human factors to the reliability of testing. Another incentive for our studies has been to test and evaluate the applicability of the international results in the Finnish circumstances. Three successive studies have thus been carried out on the human and organisational factors in non-destructive testing. (author)

    Objective: To observe and analyze related factors of neonatal asphyxia complicated with retinal hemorrhage. Methods: It was a retrospective case series. Seven hundred and twenty-one cases with neonatal asphyxia after 72 hours of birth were enrolled in this study. Fundus examination was performed on these newborns using the third generation wide-angle digital retina imaging system (RetCamⅢ), and the bleeding level was divided into level I, level Ⅱ and level Ⅲ. The conditions of the newborn and the mother during pregnancy were correlatively analyzed. The other factors were also analyzed including delivery mode, birth weight, gestational age, gender, grade of neonatal asphyxia, scalp hematoma, intracranial hemorrhage, fetal intrauterine distress, mother's age and antenatal complications. Single factor χ(2) test and multivariate logistic regression analysis were used to screen and judge risk factors causing retinal hemorrhage related to neonatal asphyxia. Results: In 721 cases of neonatal asphyxia, retinal hemorrhage was found in 204 newborns (28.29%). The hemorrhage was at level Ⅰ in 77 cases (37.75%) , at level Ⅱ in 38 cases (18.63%) and at level Ⅲ in 89 cases (43.63%) . Four cases also had vitreous hemorrhage. Asphyxia was mild in 673 infants (93.34%) and severe in 48 infants (6.66%). The difference in the degree of retinal hemorrhage between the patients with mild and severe asphyxia was significant (χ(2)=22.336, P= 0.000). When asphyxia was aggravated, the degree of retinal hemorrhage increased. Relative factors analysis showed that delivery mode (χ(2)=158.643, Pneonatal asphyxia (χ(2)=19.809, Phemorrhage. Logistic regression analysis indicated that grade of neonatal asphyxia and delivery mode were risk factors of retinal hemorrhage in neonatal asphyxia ( OR= 0.304, 0.085). Conclusion: The incidence of retinal hemorrhage in neonatal asphyxia was 28.29%. The degree of neonatal asphyxia and delivery mode may play roles in the occurrence of retinal

    This paper aims to provide a scientifically based perspective on issues surrounding the proposed toxicology testing of synthetic drug metabolites as a means of ensuring adequate nonclinical safety evaluation of drug candidates that generate metabolites considered either to be unique to humans or are present at much higher levels in humans than in preclinical species. We put forward a number of theoretical considerations and present several specific examples where the kinetic behavior of a preformed metabolite given to animals or humans differs from that of the corresponding metabolite generated endogenously from its parent. The potential ramifications of this phenomenon are that the results of toxicity testing of the preformed metabolite may be misleading and fail to characterize the true toxicological contribution of the metabolite when formed from the parent. It is anticipated that such complications would be evident in situations where (a) differences exist in the accumulation of the preformed versus generated metabolites in specific tissues, and (b) the metabolite undergoes sequential metabolism to a downstream product that is toxic, leading to differences in tissue-specific toxicity. Owing to the complex nature of this subject, there is a need to treat drug metabolite issues in safety assessment on a case-by-case basis, in which a knowledge of metabolite kinetics is employed to validate experimental paradigms that entail administration of preformed metabolites to animal models

    To determine risk factors associated with the presence of complications with mechanical ventilatory support (MVS) in the preterm infants (PI). One hundred thirty medical records of PI that had been discharged by amelioration or death were reviewed retrospectively. They were divided in two groups: group A, PI that had presented complications during MVS (cases) and B, PI with MVS, but that had not presented complications due to the procedure (controls). Statistical significance was considered at p < 0.05. The significative risk factors in the multivariate analysis reached significance for the associated of complications: gestational age (32 weeks or less), orotracheal reintubations three o more times, cycles of 60 per minute or more at the third day of being had initiate the MVS, and the symptomatic patent ductus arteriosus (PDA), all with p < 0.05. It will be necessary to impact more on the cycles level to diminish him below 60 per minute to the third day when it is feasible, to make the smallest reintubations number, to correct quickly the PDA when it is symptomatic, to avoid this way as much as possible, the complications of the MVS.

    Purpose: To quantitatively evaluate dose conformity achieved using Gamma Knife radiosurgery, compare results with those reported in the literature, and evaluate risk factors for complications. Methods and Materials: All lesions treated at our institution with Gamma Knife radiosurgery from May 1993 (when volume criteria were routinely recorded) through December 1998 were reviewed. Lesions were excluded from analysis for reasons listed below. Conformity index (the ratio of prescription volume to target volume) was calculated for all evaluable lesions and for lesions comparable to those reported in the literature on conformity of linac radiosurgery. Univariate Cox regression models were used to test for associations between treatment parameters and toxicity. Results: Of 1612 targets treated in 874 patients, 274 were excluded, most commonly for unavailability of individual prescription volume data because two or more lesions were included within the same dose matrix (176 lesions), intentional partial coverage for staged treatment of large arteriovenous malformations (AVMs) (33 lesions), and missing target volume data (26 lesions). The median conformity indices were 1.67 for all 1338 evaluable lesions and 1.40-1.43 for lesions comparable to two linac radiosurgery series that reported conformity indices of 1.8 and 2.7, respectively. Among all 651 patients evaluable for complications, there were one Grade 5, eight Grade 4, and 27 Grade 3 complications. Increased risk of toxicity was associated with larger target volume, maximum lesion diameter, prescription volume, or volume of nontarget tissue within the prescription volume. Conclusions: Gamma Knife radiosurgery achieves much more conformal dose distributions than those reported for conventional linac radiosurgery and somewhat more conformal dose distributions than sophisticated linac radiosurgery techniques. Larger target, nontarget, or prescription volumes are associated with increased risk of toxicity

    The purpose of the present study was to review the complications of ureteroscopy (URS) by using the modified Clavien classification system (MCCS) and to investigate the factors associated with complications. Data regarding 811 patients who underwent URS for ureteral calculus were analyzed. Peroperative and postoperative complications were recorded. The patients were divided into seven groups depending on the severity of the complications. The association of sex, stone size, number, and localization with each MCCS grade was also evaluated. The average age was 45 years. The success of the procedure after one session was 93.5%. Complications were recorded in 57.9% of the patients. According to the MCCS, grade I, II, IIIa, IIIb, IVa, IVb, and V complications were documented in 29.8%, 7.1%, 8.6%, 11%, 0%, 1.2%, and 0% of the patients, respectively. The factors associated with the complications graded by MCCS were sex, stone size, number of stones, and localization. In addition, in multivariate analysis, history of previous surgeries for urolithiasis, orifice dilatation, and instrument size were associated with complications. According to MCCS, sex, history of previous surgeries for urolithiasis, orifice dilatation, size of the instrument, stone size, number of stones, and localization are associated with different grades of complications in URS.

    Full Text Available Objective: Predictive factors that could affect the cure and complication rates of midurethral slings (MUS in the treatment of stress urinary incontinence (SUI were investigated. Materials and Methods: A total of 594 women (outside-in transobturator in 285, inside-out transobturator in 91, and retropubic in 218 with SUI and who had undergone MUS were evaluated. The median age was 53.9 (27-82 years. Univariate analyses were done using chi-square test, Student’s t-test and the Mann-Whitney U test. Multivariate analyses were done using logistic regression analysis to determine predictive factors affecting cure and complication rates. Results: The mean follow-up time was 48 months. The subjective cure rate was 84% and complication rate was 11.2%. On univariate and multivariate analyses, the cure rate was found to be increased in younger patients [odds ratio (OR: 0.97, 95% confidence interval (CI: 0.95-0.99, p=0.038] and in patients with pure SUI (OR: 2.17, 95% CI: 1.31-3.60, p=0.002. The type of surgery was the only statistically significant parameter affecting the complication rate, which was significantly higher in retropubic MUS procedure (OR: 6.28, 95% CI: 3.51-11.22, p<0.001. Conclusion: MUS is an effective and safe surgical procedure in the treatment of SUI. In this study, age and type of incontinence were the only significant predictive factors affecting the cure rate. Our study suggests that retropubic approach could be considered a risk factor for complication after MUS.

    Limb length discrepancy (LLD) and other patient factors are thought to influence the complication rate in (paediatric) limb deformity correction. In the literature, information is conflicting. This study was performed to identify clinical factors that affect the complication rate in paediatric lower-limb lengthening. A consecutive group of 37 children was analysed. The median proportionate LLD was 15 (4-42)%. An analysis was carried out on several patient factors that may complicate the treatment or end result using logistic regression in a polytomous logistic regression model. The factors analysed were proportionate LLD, cause of deformity, location of corrected bone, and the classification of the deformity according to an overall classification that includes the LLD and all concomitant deformity factors. The median age at the start of the treatment was 11 (6-17) years. The median lengthening index was 1.5 (0.8-3.8) months per centimetre lengthening. The obstacle and complication rate was 69% per lengthened bone. Proportionate LLD was the only statistically significant predictor for the occurrence of complications. Concomitant deformities did not influence the complication rate. From these data we constructed a simple graph that shows the relationship between proportionate LLD and risk for complications. This study shows that only relative LLD is a predictor of the risk for complications. The additional value of this analysis is the production of a simple graph. Construction of this graph using data of a patient group (for example, your own) may allow a more realistic comparison with results in the literature than has been possible before.

    Unrecognized and inadequately repaired intraoperative durotomies may lead to cerebrospinal fluid leak, pseudomeningocele, and other complications. Few studies have investigated durotomy that is unrecognized intraoperatively and requires additional postoperative management (hereafter, late-presenting dural tear [LPDT]), although estimates of LPDT range from 0.6 to 8.3 per 1,000 spinal surgeries. These single-center studies are based on relatively small sample sizes for an event of this rarity, all with <10 patients experiencing LPDT. This investigation is the largest yet conducted on LPDT, and sought to identify incidence, risk factors for, and complications associated with LPDT. This observational cohort study employed the American College of Surgeons National Surgical Quality Improvement Program dataset (years 2012-2015). Patients who underwent spine surgery were identified based on presence of primary listed Current Procedural Terminology (CPT) codes corresponding to spinal fusion or isolated posterior decompression without fusion. The primary variable in this study was occurrence of LPDT, identified as reoperation or readmission with durotomy-specific CPT or International Classification of Diseases, Ninth Revision, Clinical Modification codes but without durotomy codes present for the index procedure. Descriptive statistics were generated. Bivariate and multivariate analyses were conducted using chi-square tests and multiple logistic regression, respectively, generating both risk factors for LPDT and independent association of LPDT with postoperative complications. Statistical significance was defined as p<.05. In total, 86,212 patients were analyzed. The overall rate of reoperation or readmission without reoperation for LPDT was 2.0 per 1,000 patients (n=174). Of LPDT patients, 97.7% required one or more unplanned reoperations (n=170), and 5.7% of patients (n=10) required two reoperations. On multivariate analysis, lumbar procedures (odds ratio [OR] 2.79, p

    To estimate the prevalence of diabetic foot complications among patients at a specialist diabetes clinic in Jamaica and identify factors associated with foot complications. A stratified random sample of 188 patients were interviewed and examined between 2009 and 2010. Trained nurses obtained demographic and clinical data, measured anthropometrics and performedfoot examinations including inspection for amputations, ulcers or infection and assessment of pain, vibration and pressure perception. Participants included 143 women and 45 men (mean age 56years; mean diabetes duration 16 years). The prevalence of amputations was 8.5% (95% CI 4.5, 12.5%) and was higher among men (22.2%) compared to women (4.2%, p foot infections was 4.3% and 3.7%, respectively. Overall, 12% ofpatients had at least one of these foot complications. Foot complications were more prevalent among men, patients with high blood pressure (BP > or = 130/80 mmHg) or peripheral neuropathy In multivariable logistic regression models, factors associated with foot complications were: neuropathy (OR 9.3 [95% CI 2.8, 30.3]), high BP (OR 7.9 [1.3, 49.7]) and diabetes duration (OR 1.32 [1.02, 1.72]). Approximately one of every eight patients in this specialist clinic had a major foot complication. Associated factors were neuropathy, high blood pressure and longer duration of diabetes.

    The mechanical ventilatory assistance (MVA) is a procedure that is used very often in the neonatal intensive care units but its use its linked to a lot of complications. The objective of this study was to determine the risk factors for the presence of complications of the MVA in the newborns infants. One hundred thirty five medical records from January 98 to June 2000 of newborns that had been discharged by amelioration or death were reviewed retrospectively. All of them had been received MVA; twenty medical record were excluded. They were divided in two groups: group A, neonates that had presented complications during MVA, composed of 40 patients (cases) and B, neonates with MVA, but that had not presented complications due to the procedure of 75 patients (controls). In group A there were 39 preterm neonates and in B, 58 preterm neonates, the rest were term neonates. It was used descriptive and inferential statistics. Odds ratio (OR) and multivariate analysis were used to study risk factors with confidence interval (CI) of 95%. Statistical significance was considered at p newborn patients critically ill, with low birth weight, low gestational age, with RDS, who need more ventilatory support will be more liable to have complications and, as consequence, the mortality will be increased. For this reason it is essential a close monitoring of this group of patients for not over supporting them in IOF, PIP and cycles, thus avoiding as far as possible, the complications of the MVA.

    To examine the clinical risk factors and complications of shoulder dystocia today and to evaluate ultrasound methods predicting it. Retrospective, matched case-control study at a University Hospital with 5000 annual deliveries. The study population consisted of 152 deliveries complicated by shoulder dystocia over a period of 8.5 years (January 2004-June 2012) and 152 controls matched for gestational age and parity. The data was collected from the medical records of mothers and children and analyzed by conditional logistic regression. Incidences and odds ratios were calculated for risk factors and complications. Antenatal ultrasound data was analyzed when available by conditional logistic regression to test for significant differences between study groups. Birthweight (OR 12.1 for ≥4000 g; 95% CI 4.18-35.0) and vacuum extraction (OR 3.98; 95% CI 1.25-12.7) remained the most significant clinical risk factors. Only a trend of an association of pregestational or gestational diabetes was noticed (OR 1.87; 95% CI 0.997-3.495, probability of type II error 51%). Of the complications of shoulder dystocia the incidence of brachial plexus palsies was high (40%). Antenatal ultrasound method based on the difference between abdominal and biparietal diameters had a significant difference between cases and controls. The impact of diabetes as a risk factor has diminished, which may reflect improved screening and treatment. Antenatal ultrasound methods are showing some promise, but the predictive value of ultrasound alone is probably low. Copyright © 2014. Published by Elsevier Ireland Ltd.

    To determine which specific groups of occupational stress factors influence the duration of temporary work disability related to arterial hypertension and joint complications/co-morbidities. Workers (n = 1398; 1009 in the exposed group, 389 in the control group) with arterial hypertension who worked at one workplace for a minimum of 10 years were divided into 10 subgroups, depending on the presence of joint complications/co-morbidities. The intensity of seven groups of occupational stress factors, the total score of Occupational Stress Index (OSI) and the average number of lost working days during 1 year were analysed. The number of lost working days due to arterial hypertension and joint complications/co-morbidities was significantly higher in the exposed group. In all subgroups of the exposed group there was a high correlation between the number of lost working days and the total OSI score. Specific occupational stress factors were associated with specific complications: High Demands with chronic myocardial infarction, Strictness with cerebral haemorrhage, Conflict/Uncertainty with cerebral infarction, Extrinsic Time Pressure with acute myocardial infarction, and Avoidance/Symbolic Aversiveness with non-insulin-dependent diabetes. There are specific groups of occupational stress factors which can influence the duration of work disability associated with certain complications and co-morbidities of arterial hypertension.

    Elective surgery for uncomplicated peptic ulcer has shown a significant decrease; however, complications such as perforation and obstruction persist and require urgent surgical management. The aim of this study was to identify factors associated with early postoperative complications and mortality of patients admitted to the emergency department with perforated peptic ulcer. We performed a clinical, retrospective, cross-sectional and descriptive study of patients who were treated at the General Hospital of Mexico with a diagnosis of perforated peptic ulcer from January 2006 to December 2008. Thirty patients were included in the study. We studied several clinical findings upon admission to the emergency department and intraoperative patient findings in order to determine the association of those with early postoperative complications and mortality. We studied 30 patients with an average age of 57.07 years (± 14.2 years). The male:female ratio was 2:1. We found that the risk of developing postoperative complications was 66.7% and is significantly influenced by time of onset of abdominal pain prior to admission, bloating, septic shock and blood type O positive. Mortality was 16.7% and was correlated with the presence of septic shock on admission. The surgical procedure performed was primary closure with Graham patch in 86.6%. Average hospital stay was 12.8 days. The presence of early postoperative complications is associated with time of onset of abdominal pain before admission, abdominal distension, blood type O positive and the presence of septic shock on admission.

    To prospectively analyze the prognostic factors for neurological complications of childhood bacterial meningitis. This prospective study enrolled 77 children from 1 month until 16 years of age, treated for bacterial meningitis during the period of January 1, 2009 through December 31, 2010. 16 relevant predictors were chosen to analyze their association with the incidence of neurological complications. p-values 5,000 cells/mm(3), pleocytosis > 5,000 cells/mm(3) after 48 hours, CSF/blood glucose ratio 48 hours, presence of comorbidity, and primary focus of infection were not associated with increased risk for the development of neurological complications. Age < 12 months and severity of clinical presentation at admission were identified as the strongest predictors of neurological complications and may be of value in selecting patients for more intensive care and treatment.

    Full Text Available INTRODUCTION Despite high graft and recipient survival figures worldwide today, a variety of technical complications can threaten the transplant in the postoperative period. Vascular complications are commonly related to technical problems in establishing vascular continuity or to damage that occurs during donor nephrectomy or preservation [13]. AIM The aim of the presenting study is to evaluate counts and rates of vascular complications after renal transplantation and to compare the outcome by donor type. MATERIAL AND METHODS A total of 463 kidneys (319 from living related donor LD and 144 from cadaveric donor - CD were transplanted during the period between June 1975 and December 1998 at the Urology & Nephrology Institute of Clinical Centre of Serbia in Belgrade. Average recipients' age was 33.7 years (15-54 in LD group and 39.8 (19-62 in CD group. Retrospectively, we analyzed medical records of all recipients. Statistical analysis is estimated using Hi-squared test and Fischer's test of exact probability. RESULTS Major vascular complications including vascular anastomosis thrombosis, internal iliac artery stenosis, internal iliac artery rupture obliterant vasculitis and external iliac vein rupture were analyzed. In 25 recipients (5.4% some of major vascular complications were detected. Among these cases, 22 of them were from CD group vs. three from LD group. Relative rate of these complications was higher in CD group vs. LD group (p<0.0001. Among these complications dominant one was vascular anastomosis thrombosis which occurred in 18 recipients (17 from CD vs. one from LD. Of these recipients 16 from CD lost the graft, while the rest of two (one from each group had lethal outcome. DISCUSSION Thrombosis of renal allograft vascular anastomosis site is the most severe complication following renal transplantation. In the literature, renal allograft thrombosis is reported with different incidence rates, from 0.5-4% [14, 15, 16]. Data from the

    The prevalence of severe coronary artery disease in peripheral vascular patients exceeds 50 per cent. Complications of coronary artery disease are the most common causes of mortality following peripheral vascular operations. To reduce the incidence of cardiac complications, it is first necessary to identify patients at risk through screening tests. Screening methods in current use include risk factor analysis, exercise testing, routine coronary angiography, and dipyridamole thallium-201 scintigraphy. The risk factor approach has the advantage of being widely applicable since it makes use of historical, physical, and electrocardiographic findings that are already familiar to surgeons and anesthesiologists. It is also inexpensive. However, it may overlook the patient who has no symptoms of coronary artery disease, possibly as a result of the sedentary lifestyle imposed by complications of peripheral vascular disease. The electrocardiographically monitored stress test will identify the asymptomatic patient with occult coronary disease and is helpful in predicting operative risk. However, a meaningful test is dependent on the patient's ability to exercise--an activity that is frequently limited by claudication, amputation, or arthritis. Exercise testing also suffers from a lack of sensitivity and specificity when compared with coronary arteriography. Routine preoperative coronary angiography overcomes the exercise limitation of treadmill testing but is not widely applicable as a screening test for reasons of cost and inherent risk. Dipyridamole thallium-201 scanning, on the other hand, is safe and of relatively low cost and does not require exercise

    The aim of this study was to confirm the associated M2/ANXA5 carrier risk in women with placenta-mediated pregnancy complications (PMPC) and to test their male partners for such association. Further analysis evaluated the influence of maternal vs. paternal M2 alleles on miscarriage. Two hundred eighty-eight couples with preeclampsia (PE), intrauterine growth restriction (IUGR), or premature birth (PB) were recruited (n = 96 of each phenotype). The prevalence of the M2 haplotype was compared to two control cohorts. They included a group of women with a history of normal pregnancy without gestational pathology (Munich controls, n = 94) and a random population sample (PopGen controls, n = 533). Significant association of M2 haplotype and pregnancy complications was confirmed for women and for couples, where prevalence was elevated from 15.4 to 23.8% (p pregnancy complication. M2/ANXA5 appears to be a risk factor for adverse pregnancy outcomes related, but not limited to miscarriages, with similar prevalence in women and their male partners. These findings support the proposed physiological function of ANXA5 as an embryonic anticoagulant that appears deficient in contiguous specter of thrombophilia-related pregnancy complications culminating more frequently in miscarriage in a maternal M2 carrier background.

    Objective. To retrospectively determine the frequency and risk factors of various side effects and complications after percutaneous computed tomography-guided radiofrequency (RF) ablation of lung tumors. Methods. We reviewed and analyzed records of 112 treatment sessions in 57 of our patients (45 men and 12 women) with unresectable lung tumors treated by ablation. Risk factors, including sex, age, tumor diameter, tumor location, history of surgery, presence of pulmonary emphysema, electrode gauge, array diameter, patient position, maximum power output, ablation time, and minimum impedance during ablation, were analyzed using univariate and multivariate analyses. Results. Total rates of side effects and minor and major complications occurred in 17%, 50%, and 8% of treatment sessions, respectively. Side effects, including pain during ablation (46% of sessions) and pleural effusion (13% of sessions), occurred with RF ablation. Minor complications, including pneumothorax not requiring chest tube drainage (30% of sessions), subcutaneous emphysema (16% of sessions), and hemoptysis (9% of sessions) also occurred after the procedure. Regarding major complications, three patients developed fever >38.5 deg. C; three patients developed abscesses; two patients developed pneumothorax requiring chest tube insertion; and one patient had air embolism and was discharged without neurologic deficit. Univariate and multivariate analyses suggested that a lesion located ≤1 cm of the chest wall was significantly related to pain (p < 0.01, hazard index 5.76). Risk factors for pneumothorax increased significantly with previous pulmonary surgery (p < 0.05, hazard index 6.1) and presence of emphysema (p <0.01, hazard index 13.6). Conclusion. The total complication rate for all treatment sessions was 58%, and 25% of patients did not have any complications after RF ablation. Although major complications can occur, RF ablation of lung tumors can be considered a safe and minimally invasive

  4. Are "Human Factors" the Primary Cause of Complications in the Field of Implant Dentistry?

    Complications in medicine and dentistry are usually analyzed from a purely technical point of view. Rarely is the role of human behavior or judgment considered as a reason for adverse outcomes. When the role of human factors is considered, these are usually described in general terms rather than specifically identifying the factors responsible for an adverse event. The impact of cognitive and behavioral factors in the explanation of adverse events has been studied in other high-stakes areas such as aviation and nuclear power. Specific protocols have been developed to reduce rates of human error, and, where human error is unavoidable, to lessen its impact. This approach has dramatically reduced the incidence of accidents in these fields. This article aims to review how a similar approach may prove valuable in the reduction of complications in implant dentistry.

    The complications of hypertension cause severe health problems in rural areas in China. We (i) screened the major factors inducing hypertensive complications and provided intervention measures; and (ii) verified the efficacy of the New Rural Cooperative Medical Scheme (NRCMS; a medical insurance scheme for rural residents) for hypertension management. A survey was conducted in the villages of Yunnan (an underdeveloped province in southwest China). The NRCMS was initiated there in 2005. Data were collected through questionnaires, physical examination, electrocardiography, as well as blood and urine tests. To detect factors inducing hypertension complications, a generalized estimating equations model was developed. Multivariable logistic regression was used to analyze influencing factors for hypertension control. Poor management of hypertension was observed in women. Being female, old, poorly educated, a smoker, ignorant of the dangerousness of hypertension, and having uncontrolled hypertension made patients more prone to hypertension complications. Combination therapy with ≥ 2 drugs helped control hypertension, but most rural patients disliked multidrug therapy because they considered it to be expensive and inconvenient. The NRCMS contributed little to reduce the prevalence of complications and improve control of hypertension. The present study suggested that the NRCMS needs to be reformed to concentrate on early intervention in hypertension and to concentrate on women. To increase hypertension control in rural areas in China, compound products containing effective and inexpensive drugs (and not multidrug therapy) are needed.

    BACKGROUND Pemphigus is an autoimmune blistering disease. According to a report, in areas of endemic pemphigus foliaceus (EPF) in Peru there are cases of pemphigus vulgaris with epidemiologic, clinical and histopathologic characteristics similar to those of "endemic pemphigus vulgaris" (EPV) in Brazil. OBJECTIVES To determine the clinical and epidemiologic characteristics of endemic pemphigus and the risk factors of patients for developing complications during treatment. METHODS A study was carried out from July 2003 to March 2008. The study population was 60 patients with EPF and 7 patients with EPV evaluated in hospitals and clinics in the Peruvian Amazon and Lima. A multivariate analysis was carried out using binary logistic regression. RESULTS The average age of EPF patients was 31.4 years; 55% were men; 60% presented the generalized clinical variant. Non-compliance with the treatment was seen in 57.1% of the patients. Thirty-five percent presented complications (e.g. pyodermitis and pyelonephritis) during treatment. The risk factors for developing complications during treatment were non-compliance with the treatment and having the generalized clinical form. In the EPV group, the average age was 21.7 years; 71.4% were men. All patients presented with the mucocutaneous clinical variant and the initial presentation consisted of oral mucosa lesions; 71.4% presented complications during treatment, pyodermitis being the most frequent. CONCLUSIONS Non-compliance with the treatment and the generalized clinical form are risk factors for the development of complications during treatment of patients with EPF. Peru indeed has EPV cases with epidemiologic characteristics similar to EPF. Living in a rural area may represent a risk factor for the development of complications during treatment of patients with EPV. PMID:23197201

    Objectives African American maternal caregiver support for prevention of childhood obesity may be a factor in implementing, monitoring, and sustaining children's positive health behaviors. However, little is known about how perceptions of childhood obesity risk factors and health complications influence caregivers' support of childhood obesity prevention strategies. The objective of this study was to determine if childhood obesity risk factors and health complications were associated with maternal caregivers' support for prevention initiatives. Methods A convenience sample of maternal caregivers (N = 129, ages 22-65 years) completed the childhood obesity perceptions (COP) survey. A linear regression was conducted to determine whether perceptions about childhood obesity risk factors and subsequent health complications influenced caregivers' support for prevention strategies. Results Caregivers' perceptions of childhood obesity risk factors were moderate (M = 3.4; SD = 0.64), as were their perceptions of obesity-related health complications (M = 3.3; SD = 0.75); however, they perceived a high level of support for prevention strategies (M = 4.2; SD = 0.74). In the regression model, only health complications were significantly associated with caregiver support (β = 0.348; p obesity prevention efforts should emphasize health complications by providing education and strategies that promote self-efficacy and outcome expectations among maternal caregivers.

    Cardiovascular changes associated with neuraxial blocks are a cause of concern due to their frequency and because some of them can be considered physiological effects triggered by the sympathetic nervous system blockade. The objective of this study was to evaluate intraoperative cardiovascular complications and predictive factors associated with neuraxial blocks in patients ≥ 18 years of age undergoing non-obstetric procedures over an 18-year period in a tertiary university hospital--HCFMB-UNESP. A retrospective analysis of the following complications was undertaken: hypertension, hypotension, sinus bradycardia, and sinus tachycardia. These complications were correlated with anesthetic technique, physical status (ASA), age, gender, and preoperative co-morbidities. The Tukey test for comparisons among proportions and logistic regression was used for statistical analysis. 32,554 patients underwent neuraxial blocks. Intraoperative complications mentioned included hypotension (n=4,109), sinus bradycardia (n=1,107), sinus tachycardia (n=601), and hypertension (n=466). Hypotension was seen more often in patients undergoing continuous subarachnoid anesthesia (29.4%, OR=2.39), ≥ 61 years of age, and female (OR=1.27). Intraoperative hypotension and bradycardia were the complications observed more often. Hypotension was related to anesthetic technique (CSA), increased age, and female. Tachycardia and hypertension may not have been directly related to neuraxial blocks. Copyright © 2011 Elsevier Editora Ltda. All rights reserved.

    To prospectively evaluate the incidence of delayed complications (bleeding, pain, infection) following CT-guided biopsies of bone or soft tissue lesions and to identify risk factors that predispose to their occurrence. All adults presenting for CT-guided biopsy of a bone or soft tissue lesion were eligible for the study. Risk factors considered included patient gender and age, bone versus soft tissue, lesion location, lesion depth, anticoagulation, conscious sedation, coaxial biopsy technique, bleeding during the biopsy, dressing type and duration of placement, final diagnosis, needle gauge, number of passes, and number of days to follow-up. Outcomes measured included fever, pain, bruising/hematoma formation, and swelling and were collected by a follow-up phone call within 14 days of the biopsy. Fisher's exact test, the Wald Chi-square test, and univariate, multivariate, and stepwise logistic regression were performed to evaluate the influence of the risk factors on the outcomes. A total of 386 patients participated in the study. The rates of post-biopsy fever, pain, bruising, and swelling were 1.0, 16.1, 15.6, and 9.6 %, respectively. Anticoagulants were identified as a risk factor for fever. Increasing patient age was identified as a risk factor for pain. Female gender and lesion location were identified as risk factors for bruising. Increasing patient age and lesion location were identified as risk factors for swelling. Patient age, female gender, and lesion location are risk factors for delayed minor complications following CT-guided biopsy of a bone or soft tissue lesion. There were no major complications. None of the complications in this series altered patient management. (orig.)

    Understanding the factors that can predict greater quality of life (QoL) is important for adults with spinal cord injury (SCI), given that they report lower levels of QoL than the general population. To build a conceptual model linking SCI-related needs, secondary complications, and QoL in adults with SCI. Prior to testing the conceptual model, we aimed to develop and evaluate the factor structure for both SCI-related needs and secondary complications. Individuals with a traumatic SCI (N = 1,137) responded to an online survey measuring 13 SCI-related needs, 13 secondary complications, and the Life Satisfaction Questionnaire to assess QoL. The SCI-related needs and secondary complications were conceptualized into factors, tested with a confirmatory factor analysis, and subsequently evaluated in a structural equation model to predict QoL. The confirmatory factor analysis supported a 2-factor model for SCI related needs, χ(2)(61, N = 1,137) = 250.40, P SCI-related needs (β = -.22 and -.20, P SCI-related needs of individuals with SCI and preventing or managing secondary complications are essential to their QoL.

    To evaluate the ways of reduction complications during endoscopic procedures based on principals of professional ethics and improving the quality of working area. Data of fundamental literature, evidence based medicine, science publications and internet portals. Deontology is the fundamental principle of medical practice and one of the main factors of professional effectiveness. Complications in endoscopy are often the investigations of deviation from the deontological principals. The whole number of psychological factors influences on professional activity of endoscopists, where the emotional "burn-out" syndrome (EBS) occupies one of the main places. Prophylactic and timely relief of EBS serves improvement of the practical work quality. Creation of favorable working area is the strategically important task in prophylactics of endoscopy complications. The questions of practical realization of deontological principles in endoscopy are the subject of further discussion.

    Full Text Available Contact lenses are freely available without professional examination and fitting, as well as without adequate introduction and instructions on handling, disinfection and storage. Contact lenses may have physiological, metabolic and anatomic effect on the eyes, which is manifested both on the eyelids, lacrimal film, conjunctiva and in all layers of the cornea - the epithelium, stroma and the endothelium. We can see these complications too often at our everyday work. The purpose of this paper is to draw attention to the potential complications due to inappropriate use of contact lenses.Contact lenses are otherwise a safe and effective method of correcting visual acuity; they are also useful for therapeutic purposes. Complications related to contact lenses wear could be largely avoided with an appropriate professional approach and the compliance of contact lens wearers. It is important to discuss with patients their medical history, their desires and expectations, their working and living environment; followed by professional examination of patients and appropriate fitting of contact lenses. Patients should receive detailed oral and written instructions and be subscribed to regular checks. But unfortunately, all this is not enough, if patients do not comply every day with given instructions.

    A 58-year-old man was admitted to our hospital. Laboratory data showed severe liver injury and that the patient was positive for immunoglobulin M anti-hepatitis A virus (HAV) antibodies. He was also complicated with severe renal dysfunction and had an extremely high level of serum hepatocyte growth factor (HGF). Therefore, he was diagnosed with severe acute liver failure with acute renal failure (ARF) caused by HAV infection. Prognosis was expected to be poor because of complications by ARF and high serum HGF. However, liver and renal functions both improved rapidly without intensive treatment, and he was subsequently discharged from our hospital on the 21(st) hospital day. Although complication with ARF and high levels of serum HGF are both important factors predicting poor prognosis in acute liver failure patients, the present case achieved a favorable outcome. Endogenous HGF might play an important role as a regenerative effector in injured livers and kidneys.

    Full Text Available Abstract Background The complications of hypertension cause severe health problems in rural areas in China. We (i screened the major factors inducing hypertensive complications and provided intervention measures; and (ii verified the efficacy of the New Rural Cooperative Medical Scheme (NRCMS; a medical insurance scheme for rural residents for hypertension management. Methods A survey was conducted in the villages of Yunnan (an underdeveloped province in southwest China. The NRCMS was initiated there in 2005. Data were collected through questionnaires, physical examination, electrocardiography, as well as blood and urine tests. To detect factors inducing hypertension complications, a generalized estimating equations model was developed. Multivariable logistic regression was used to analyze influencing factors for hypertension control. Results Poor management of hypertension was observed in women. Being female, old, poorly educated, a smoker, ignorant of the dangerousness of hypertension, and having uncontrolled hypertension made patients more prone to hypertension complications. Combination therapy with ≥2 drugs helped control hypertension, but most rural patients disliked multidrug therapy because they considered it to be expensive and inconvenient. The NRCMS contributed little to reduce the prevalence of complications and improve control of hypertension. Conclusions The present study suggested that the NRCMS needs to be reformed to concentrate on early intervention in hypertension and to concentrate on women. To increase hypertension control in rural areas in China, compound products containing effective and inexpensive drugs (and not multidrug therapy are needed.

    Mechanical complications, such as cut-out of the head-neck fixation device, are the most common causes of morbidity after trochanteric femur fracture treatment. The causes of cut-out complications are well defined in patients who are treated with sliding hip screws and biaxial cephalomedullary nails but there are few reports about the patients who are treated with proximal femoral nail antirotation. The purpose of this study was to evaluate the most important factor about occurance of cutout complication and also to evaluate the risks of the combination of each possible factors. Overally 298 patients were enrolled in the study. Medical records were reviewed for patients' age, fracture type, gender, anesthesia type and occurance of cut-out complication. Postoperatively taken radiographs were reviewed for tip-apex distance, obtained collo-diaphyseal angle, the quadrant of the helical blade and Ikuta reduction subgroup. The most important factor (s) and also predicted probability of cut-out complication was calculated for each combination of factors. Cut-out complication was observed in 14 patients (4.7 %). The most important factor about occurrence of the cut-out complication was found as varus reduction (p: 0.01), the second important factor was found as implantation of the helical blade in the improper quadrant (p: 0.02). Tip-apex distance was found as third important factor (p: 0.10). The predicted probability of cut-out complication was calculated as 45.6 % when whole of the four surgeon dependent factors were improperly obtained. Althought obtaining proper tip-apex distance is important to prevent cutout complication in these fractures, if the fracture is not reduced in varus position and helical blade is inserted in the proper quadrant, possibility of cut-out complication is very low even in the patients with high tip-apex distance.

    The forced swim test (FST) is a behavioral test in rodents which was developed in 1978 by Porsolt and colleagues as a model for predicting the clinical efficacy of antidepressant drugs. A modified version of the FST added the classification of active behaviors into swimming and climbing, in order to facilitate the differentiation between serotonergic and noradrenergic classes of antidepressant drugs. The FST is now widely used in basic research and the pharmaceutical screening of potential antidepressant treatments. It is also one of the most commonly used tests to assess depressive-like behavior in animal models. Despite the simplicity and sensitivity of the FST procedure, important differences even in baseline immobility rates have been reported between different groups, which complicate the comparison of results across studies. In spite of several methodological papers and reviews published on the FST, the need still exists for clarification of factors which can influence the procedure. While most recent reviews have focused on antidepressant effects observed with the FST, this one considers the methodological aspects of the procedure, aiming to summarize issues beyond antidepressant action in the FST. The previously published literature is analyzed for factors which are known to influence animal behavior in the FST. These include biological factors, such as strain, age, body weight, gender and individual differences between animals; influence of preconditioning before the FST: handling, social isolation or enriched environment, food manipulations, various kinds of stress, endocrine manipulations and surgery; schedule and routes of treatment, dosage and type of the drugs as well as experimental design and laboratory environmental effects. Consideration of these factors in planning experiments may result in more consistent FST results. PMID:23685235

    Full Text Available The aim of the study was to determine risk factors for recurrent bacterial complications of the upper respiratory tract viral infection (URTI in children, as well as the clinical and immunological features of the course of such complications. We enrolled 214 children aged 3-18 years with URTIs complicated with acute otitis media or acute bacterial rhinosinusitis. Frequency of bacterial complications of URI in 128 children was low (group I and in 86 children it met the criteria of recurrent course (group II. In addition to the standard examination, lysozyme levels in the oropharyngeal secretion were determined three times during the disease. It was found that children of group II were characterized by an early debut of respiratory morbidity (at the age of 6.00 (4.00, 12.00 months against 13.00 (4.50, 16.00 months in children of group I (p<0,0001, as well as a longer duration of catarrhal and intoxication syndromes in similar forms of the disease. The most significant risk factors for the formation of the recurring complication pattern were maternal smoking (OR=2.73, 95% CI [1.34, 5.48], along with gastroenterological pathology and frequent URTI in the mother and a shortened period of breastfeeding. In children with recurrent bacterial complications of URTI, there was an impaired local resistance of the upper respiratory tract mucous membranes (as a decrease in the concentrations of lysozyme in all periods of the disease, which persisted after recovery.

    Several recent studies have demonstrated the association between smoking and chronic pancreatitis (CP). However, less is known about the role of smoking in the development of CP-related complications. Our aim was to investigate the impact of smoking and alcohol consumption on age of onset and complications at CP diagnosis. A cross-sectional case-case study was performed within a prospectively collected cohort of patients with CP. Alcohol consumption and smoking habits were assessed using a standardized questionnaire. Morphologic severity was defined based on endoscopic ultrasound criteria for CP and classified as mild (3-4 criteria), moderate (5-6 criteria), and severe (≥7 criteria or calcifications). Pancreatic exocrine insufficiency (PEI) was diagnosed using the C-mixed triglyceride breath test. Odds ratios (OR) with 95% confidence intervals (CI) for CP-related complications were calculated using a case-case design. A total of 241 patients were included. Smoking was associated with PEI (OR [95% CI], 2.4 [1.17-5.16]), calcifications (OR [95% CI], 2.33 [1.10-4.95]), and severe morphologic changes (OR [95% CI], 3.41 [1.31-8.85]) but not with pseudocysts or diabetes. Neither smoking nor alcohol consumption was associated with age of onset. Tobacco, but not alcohol, is associated with PEI, calcifications, and severe morphologic (≥7 criteria or calcifications) CP at diagnosis. Smoking cessation should be encouraged in patients with CP.

    Biliary complications (BC) occur in up to 39.5% of patients after orthotopic liver transplantation (OLT), being an important source of post-transplant morbidity. The aim is to evaluate the incidence of BC after OLT, associated risk factors and outcome after endoscopic treatment. A retrospective case series between June 2005 and December 2008, including 195 patients that underwent 216 OLT from deceased donors. Thirty-one patients (14.3%) presented at least 1 BC, anastomotic stricture being the most frequent (83.8%). Non-anastomotic stricture was present in 1 (3.2%) and anastomotic fistula in 1. One patient presented anastomotic disconnection at ERCP. BC occurred 94.6 (7-487) days after OLT. Twenty-seven patients underwent endoscopic treatment, on average 2.6 ERCPs were performed per patient. Global endoscopic treatment success rate was 77.3%; being 73.7% for stenosis and 100% (3/3) for anastomotic fistula with stenosis. Recurrence of biliary stricture was observed in 3 patients, all referred to endoscopic re-treatment. ERCP complications: 2 (2.8%) stent migrations, 1 (1.4%) early stent occlusion, 1 (1.4%) respiratory distress and 1(1.4%) severe acute pancreatitis and death. There was no correlation between studied risk factors and BC's occurrence. ERCP was effective for the treatment of BC after OLT. Studied risk factors had no correlation with BC.

    Objective: To investigate the prognosis and prognostic risk factors of hepatic artery complications after orthotopic liver transplantation (OLT) treated with the interventional techniques. Methods: The clinical data of 21 patients with hepatic artery complication after liver transplantation receiving thrombolysis, PTA, and stent placement in our institute from November 2003 to April 2007 were retrospectively analyzed. Based on the prognosis of grafts, 21 patients were divided into poor-prognosis group and non-poor-prognosis group. Fifteen variables (including biliary complication, hepatic artery restenosis, early or late artery complication, and so on) were analyzed in both groups with binary logistic regression analysis to screen out the risk factors related to prognosis of pereutaneous interventional treatment for hepatic artery complications after OLT. Results: Twenty-one patients were followed for mean 436 days, median 464 days (3-1037 days). The poor-prognosis group included 11 patients (5 cases received retransplantation, and 6 died). The mean survival time of grafts in poor-prognosis group was 191 days, and median survival time was 73 days (3-616 days). The mean survival time of grafts in non-poor-prognosis group which included 10 patients was 706 days, and median survival time was 692 days (245-1037 days). Univariate analysis showed there were significant difference in biliary complication, total bilimbin and indirect bilirubin between the two groups. The binary, logistic regression analysis showed the risk factor related to prognosis was with biliary complication before the interventional management (P=0.027, OR=22.818). Conclusion: Biliary complication before interventional management is the risk factor related to poor prognosis of patients with hepatic artery stenosis or thrombosis receiving interventional treatment.

    Full Text Available Background: Breast cancer is the most frequent malignant tumor in women worldwide. In recent years, defined reconstruction principles along with numerous surgical techniques with volume replacement have been published. Autologous breast reconstruction is more natural but leaves donor site morbidity. It provides the opportunity to restore the breast mound without the need for scars. This study aims to evaluate the complications of radiotherapy after immediate breast reconstruction with implants in breast cancer patients who submitted to skin sparing mastectomy and nipple sparing mastectomy by taking into consideration the risk factors and management at our institution. Methods: The current study prospectively included patients with invasive breast cancer admitted between January and June 2012 who were scheduled for skin sparing mastectomy or nipple sparing mastectomy and axillary dissection followed by immediate breast reconstruction with implant. Patients received adjuvant chemotherapy followed by conventional fractionated radiation. Complications were classified as either minor or major. The minor complications included capsular contracture (Baker 1-2, seroma, minor skin infection and skin dehiscence without exposure of the implant. Major complications included capsular contracture (Baker 3-4, severe infection and major wound dehiscence with implant exposure. Capsular contracture was scored according to the modified Baker classification. Results: The study included 38 patients. Of these, 28 had skin sparing mastectomy while 10 underwent nipple sparing mastectomy. The overall complication rate was 71%. We observed minor complications in 18 patients while 9 patients had major complications. Complications occurred with a median time of 13 months following radiotherapy completion. All minor complications were managed conservatively whereas all major complications required repeat surgery. No loco-regional recurrences occurred during the follow up

    To determine the incidence of early postoperative complications and associated factors after primary trabeculectomy in Thai glaucoma patients. This was a retrospective observational study performed in Chiang Mai University Hospital. One hundred and eighteen glaucoma patients participated in the study. All glaucoma patients underwent primary trabeculectomy with mitomycin C (MMC) using fornix-based conjunctival flap technique between December 2011 and May 2013. Surgical complications during the first 3 months of follow-up were recorded, and associated risk factors were analyzed. The incidence of posttrabeculectomy complications was the main outcome measure. One hundred and eighteen eyes of 118 patients were included. Early postoperative complications developed in 55 eyes (56.7%). Complications included hypotony (25 eyes, 27.2%), serous choroidal detachment (CD) (14 eyes, 15.6%), subconjunctival hemorrhage (12 eyes, 13.0%), hyphema (11 eyes, 12.4%), bleb leak (8 eyes, 8.8%), encapsulated bleb (2 eyes, 2.2%), aqueous misdirection (1 eyes, 1.1%), corneal epithelial defect (1 eyes, 1.1%), and overfiltration (1 eyes, 1.1%). There were no reported cases of endophthalmitis or blebitis. Hypotony was associated with serous CD (P = 0.006), and hyphema was associated with neovascular glaucoma (NVG) patients (P = 0.009). NVG was not associated with the increased rate of surgical failure (P = 0.083). The incidence of early complications after first-time trabeculectomy with MMC was high (56.7%) in this Thai clinic setting, but most were transient and self-limited conditions. The correlations between hypotony and CD as well as hyphema and NVG were compatible with the previous studies.

    This study aimed to determine the role of cellular auto immunity and its humoral mediators in pathogenesis and following up of type I diabetes mellitus (TIDM). Therefore, serum concentrations of tumour necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), glycemic control, body mass index, duration of the disease and microalbuminuria in children with TIDM were evaluated. This study was conducted on 30 patients suffered from type I diabetes mellitus (TIDM), 14 males and 16 females with mean age of 11.40 ±3.67 years and 20 apparently healthy children served as control (10 male and 10 female). Children with TIDM were classified according to duration: diabetic children for 5 years or less duration (n= 15, duration means: 2.74 ± 1.34 years) and diabetic children > 5 years (n=15, duration means: 7.35 ± 1.49 years); according to glycemic control: children with good glycemic control (n=16, HbAIc: 7.82 ± 2.70) and diabetic children with poor glycemic control (n=14, HbAIc: 10.49 ± 2.72) and according to complication: diabetic children without complications (n= 20) and diabetic children with microvascular or neurological complications (n= 10, nephritic, retinal or neurological complications). Patients and controls were subjected to careful history, clinical examination and laboratory investigations. The following investigations were done for all children; random blood glucose, Glycated hemoglobin (HbAIc %), microalbuminuria and kidney function tests. Serum tumour necrosis factor-alpha (TNF-alpha) and serum interleukin-6 (IL-6) were measured using immuno-enzymometric assay (ELISA). Patients with TIDM with duration more than 5 years, with poor glycemic control and with complications had higher serum glucose levels, higher HbAIc%, higher level of blood urea nitrogen (BUN), serum creatinine, microalbuminuria and elevated serum TNF-alpha (p<0.0001) and IL-6 (p<0.0001) in comparison to the same diabetic patients with 5 years duration or less, with good glycemic control

    To estimate the prevalence of complications and describe the outcome associated with calcaneal fractures in non-racing dogs and in cats. Retrospective multicenter clinical cohort study. Medical records of client-owned dogs and cats (2004-2013). Medical records were searched and 50 animals with calcaneal fractures were included for analysis. Complications were recorded and an outcome score applied to each fracture. Associations between putative risk factors and both major complications, and final outcome scores were explored. Complications occurred in 27/50 fractures (61%) including 23 major and 4 minor complications. At final follow-up, 4 animals (10%) were sound, 27 (64%) had either intermittent or consistent mild weight-bearing lameness, 7 (17%) had moderate weight-bearing lameness, and 1 (2%) had severe weight-bearing lameness. Fractures managed using plates and screws had a lower risk of complications than fractures managed using pin and tension band wire, lag or positional screws or a combination of these techniques (Relative risk 0.16, 95% CI 0.02-1.02, P=.052). Non-sighthounds had reduced odds of a poorer outcome score than sighthounds (Odds ratio 0.11, 95% CI 0.02-0.50, P=.005) and fractures with major complications had 13 times the odds of a poorer outcome score (Odds ratio 13.4, 95% CI 3.6-59.5, Pdogs and in cats, and a poorer outcome score was more likely in animals with complications. A more guarded prognosis should be given to owners of non-racing dogs or cats with calcaneal fractures than previously applied to racing Greyhounds with calcaneal fractures. © 2016 The American College of Veterinary Surgeons.

    In rural Bangladesh, more than 75% of all births occur at home in the absence of skilled birth attendants. Population-based data are lacking on the burden and risk factors for obstetric complications in settings with low rates of institutional delivery. We sought to describe the prevalence of reported complications and to analyze risk factors for obstetric complications and near misses, using data from a representative, rural setting of Bangladesh. This study utilized existing data on 42,214 pregnant women enrolled in a micronutrient supplementation cohort trial between 2007 and 2011 in rural northwest Bangladesh. Based on self-report of complications, women were categorized as having obstetric complications, near misses, or non-complicated pregnancies using definitions modified from the World Health Organization. Multivariable multinomial regression was used to analyze the association of biological, socioeconomic, and psychosocial variables with obstetric complications or near misses. Of enrolled women, 25% (n = 10,380) were classified as having at least one obstetric complication, 2% (n = 1,004) with reported near misses, and 73% (n = 30,830) with non-complicated pregnancies. Twelve percent (n = 5,232) reported hemorrhage and 8% (n = 3,259) reported sepsis. Of the 27,241 women with live births or stillbirths, 11% (n = 2,950) reported obstructed labor and 1% (n = 328) reported eclampsia. Biological risk factors including women's age less than 18 years (Relative Risk Ratio [RRR] 1.26 95%CI:1.14-1.39) and greater than 35 years (RRR 1.23 95%CI:1.09-1.38), history of stillbirth or miscarriage (RRR 1.15 95%CI:1.07-1.22), and nulliparity (RRR 1.16 95%CI:1.02-1.29) significantly increased the risk of obstetric complications. Neither partner wanting the pregnancy increased the risk of obstetric complications (RRR 1.33 95%CI:1.20-1.46). Mid-upper arm circumference <21.5 cm increased the risk of hemorrhage and sepsis. These analyses indicate a high burden of obstetric

    Full Text Available Obstructive ileus and peritonitis are the most frequent complication of colorectal cancer, manifested in 8-40 % cases. Anastomotic leakage (AL is a fatal complication in colorectal surgery. In our study, we aim to analyze the safety, outcomes in patients with colon obstruction after resection with new anastomosis technique implementation and to identify prognostic value of each risk factor on development of AL. A retrospective analysis of prospectively acquired data of 155 consecutive emergency patients with cancer of proximal rectum and sigmoid colon complicated by chronic bowel obstruction in stage of subcompensation and decompensation were included in our study and divided into 2 groups. In the basic group (n=95, primary nonfunctional anastomosis (PNA was performed after resection of the rectum. In the comparing group (n=60, resection of the colon or rectum with primary anastomosis was performed. Results: Postoperative complications have arisen in 5 (5,3 % patients of group I and in 11 (18,4% patients of group II. AL was developed only in 1 patient in the basic group (1,1% and in 7 (11,7 % patients of the compared group on the 5th-12th day after operation. We have worked out the rate score of risk factors of AL. А score was given for each AL factor which we had selected for elaboration of this scale. Conclusions: Based on AL risk factors scale we highlighted 5 levels of risk which have significant clinical meaning and help surgeons decide finally how to finish operation in patient with bowel obstruction in order to avoid AL. PNA with preventive transversostoma was shown to provide adequate decompression of the colon, reliable prevention of colorectal AL, avoid complex reconstructive operations and be a good alternative for Hartman’s procedure.

    Diabetes is a serious disease that spread in the world dramatically. The diabetes patient has an average of risk to experience complications. Take advantage of recorded information to build ontology as information technology solution will help to predict patients who have average of risk level with certain complication. It is helpful to search and present patient's history regarding different risk factors. Discovering diabetes complications could be useful to prevent or delay the complications. We designed ontology based model, using adult diabetes patients' data, to discover the rules of diabetes with its complications in disease to disease relationship. Various rules between different risk factors of diabetes Patients and certain complications generated. Furthermore, new complications (diseases) might be discovered as new finding of this study, discovering diabetes complications could be useful to prevent or delay the complications. The system can identify the patients who are suffering from certain risk factors such as high body mass index (obesity) and starting controlling and maintaining plan.

    Full Text Available Background : The role of variables like duration of diabetes, diabetic control and microvascular complications in the causation of cognitive decline in patients with type 2 diabetes is not well studied. The contribution of hypertension to the cognitive decline in nondemented diabetic patients is unclear. Aims: We wanted to see if cognition in patients with type 2 diabetes is associated with the duration of diabetes, control of diabetes, complications of diabetes, vascular risk factors, or depression. We also looked at association of noncompliance with cognition, and depression. Settings and Design: We recruited ambulant patients with type 2 diabetes who are 55 years or more in age from the weekly diabetic clinic. We excluded patients with past history of stroke.

    The objective of this study was to identify nutritional preoperative factors associated with complications after radical cystectomy (RC). We prospectively evaluated the Mini-Nutritional Assessment Score, body mass index (BMI), appetite, stool frequency, hydration, food intake, weight loss, albuminemia, and prealbuminemia of 144 patients who underwent RC between January 2011 and April 2014. Postoperative complications were defined as any adverse event reported in the patient's file up to 90 days after surgery. Each complication was classified according to the Clavien-Dindo and Memorial Sloan-Kettering Cancer Center systems. The adjusted relative risk (RR) computed through a Poisson regression model was used to identify nutritional risk factors associated with post-RC complications. A high BMI >27 kg/m 2 was associated with higher risk of low-grade complications (RR:1.47 [95% CI,1.09-2.00]) at 7 days and a four-fold increased risk of cardiac complications at 7 and 90 days (RR:3.77 [1.15-12.32] and RR:3.28 [1.35-7.98]). Decreased appetite was associated with low-grade (RR:1.43 [1.03-1.99] complications within 90 days. Preoperative weight loss >3 kg was associated with high-grade (RR:2.49 [1.23-5.05]) and wound (RR:2.51 [1.23-5.10]) complications within 90 days. This study showed that preoperative nutritional status of patients may predict the occurrence of complications up to 90 days post-RC. Development of preoperative nutritional interventions may reduce the deleterious impact of RC on patients' health.

    Peri-anaesthetic complications are relatively common in equine patients and further investigations are warranted to identify manageable risk factors. To report morbidity and mortality rates and identify associated risk factors for horses undergoing general anaesthesia, within a predominantly racing Thoroughbred (TB) population. Single centre retrospective observational study. Anaesthetic and case records of all horses ≥12 months old undergoing general anaesthesia at Newmarket Equine Hospital between August 2010 and April 2012 were analysed, excluding emergency abdominal/dystocia procedures or traumatology cases with cardiovascular compromise. Mortality and morbidity rates were calculated and described. Uni- and multivariable analyses were used to investigate the relationship between the principal complication, post anaesthetic colic (PAC) and risk factors. A total of 1067 anaesthetic records of 1021 horses were included in the study; of these, 702 horses (65.8%) were TB, 169 (15.8%) developed a complication within 7 days of general anaesthesia and 10 (0.94%) died as a result. The most prevalent morbidity was PAC, 111 horses (10.5%) developed colic within 7 days of general anaesthesia. Thoroughbred horses (odds ratio [OR] 2.93, 95% confidence interval [CI] 1.73-4.96) and horses receiving sodium benzylpenicillin (NaBP) (OR 2.77, 95% CI 1.69-4.50) were at increased risk of PAC. Thoroughbred racehorses were identified as at increased risk of PAC in this study and might benefit from more critical evaluation of post anaesthetic gastrointestinal function. An alternative to the administration of NaBP for prophylactic antimicrobial therapy needs to be further investigated if its role in PAC is confirmed by other studies. © 2015 EVJ Ltd.

    Few prospective data are currently available on acute gastrointestinal hemorrhage (AGIH) as a complication of acute renal failure (ARF). The aim of the present study was to define incidence, sources, risk factors, and outcome of AGIH in patients with ARF. We performed a prospective study on an inception cohort of 514 patients admitted for ARF to a nephrology intermediate care unit. Data on clinical risk factors for bleeding, frequency of occurrence of AGIH, length of hospital stay, and in-hospital mortality were collected. Independent predictors of AGIH were identified. The relative odds of death and the relative increase in length of hospital stay associated with AGIH were calculated after adjusting for baseline comorbidities. Sixty-nine patients out of 514 [13.4% (95% CI, 10.6 to 16.7)] had AGIH as a complication of ARF; 59 were upper AGIH. Forty patients had clinically important bleeding. Erosions and/or ulcers accounted for 71% of cases of upper AGIH. Independent baseline predictors of AGIH were represented by severity of illness [odds ratio 1.45 (95% CI, 1.05 to 2.01) for every 10 point increase in APACHE II score], low platelet count [<50,000 mm3; 3.71 (1.70 to 8.11)], noncirrhotic chronic hepatic disease [2.22 (1.09 to 4.55)], liver cirrhosis [3.38 (1.50 to 7.60)], de novo ARF [2.77 (1.30 to 5.90)], and severe ARF [2.07 (1.10 to 3.88)]. In-hospital mortality was 63.8% in patients with AGIH and 34.2% in the other patients; after adjusting for baseline confounders, AGIH remained significantly associated with an increase in both mortality [2.57 (1.30 to 5.09), P = 0.006] and length of hospital stay [37% (1 to 87%), P = 0.047]. AGIH and clinically important bleeding are frequent complications of ARF. In this clinical condition, AGIH is more often due to upper gastrointestinal bleeding and is associated with a significantly increased risk of death and length of hospital stay. Both renal and extrarenal risk factors are related to the occurrence of AGIH.

    Background Percutaneous kyphoplasty (PKP) is a common treatment modality for painful osteoporotic vertebral compression fractures (OVCFs). Pre- and postoperative identification of risk factors for cement leakage and follow-up complications would therefore be helpful but has not been systematically investigated. Purpose To evaluate pre- and postoperative risk factors for the occurrence of short-term cement leakages and long-term complications after PKP for OVCFs. Material and Methods A total of 283 vertebrae with PKP in 239 patients were investigated. Possible risk factors causing cement leakage and complications during follow-up periods were retrospectively assessed using multivariate analysis. Cement leakage in general, three fundamental leakage types, and complications during follow-up period were directly identified through postoperative computed tomography (CT). Results Generally, the presence of cortical disruption ( P = 0.001), large volume of cement ( P = 0.012), and low bone mineral density (BMD) ( P = 0.002) were three strong predictors for cement leakage. While the presence of intravertebral cleft and Schmorl nodes ( P = 0.045 and 0.025, respectively) were respectively identified as additional risk factors for paravertebral and intradiscal subtype of cortical (C-type) leakages. In terms of follow-up complications, occurrence of cortical leakage was a strong risk factor both for new VCFs ( P = 0.043) and for recompression ( P = 0.004). Conclusion The presence of cortical disruption, large volume of cement, and low BMD of treated level are general but strong predictors for cement leakage. The presence of intravertebral cleft and Schmorl nodes are additional risk factors for cortical leakage. During follow-up, the occurrence of C-type leakage is a strong risk factor, for both new VCFs and recompression.

    Osteonecrosis is a rare complication of HIV infection. The presumptive cause of the aseptic osteonecrosis is a disturbed blood supply to the bone. Most cases of osteonecrosis are associated with numerous risk factors, such as use of steroids, alcohol abuse, coagulopathies or metabolic derangements. Since conventional X-rays appear unremarkable, early forms often go unrecognized or are diagnosed late. Methods of establishing the diagnosis are MRI and three-phase skeletal scintigraphy. The pathogenesis of osteonecrosis in HIV infection is unclear. So far, about 30 cases have been reported in the literature. We would recommend that in HIV patients with typical symptoms - in particular when classical risk factors are present - osteonecrosis be included in the differential diagnostic considerations.

    Prenatal complications are associated with poor outcomes in the offspring. Access to medical records is limited in the United States and investigators often rely on maternal report of prenatal complications. We tested concordance between maternal recall and birth records in a community-based sample of mothers participating in a longitudinal study in order to determine the accuracy of maternal recall of perinatal complications. Participants were 151 biological mothers, who were interviewed about gestational age at birth, birthweight, and the most commonly occurring birth complications: nuchal cord and meconium aspiration when the female child was on average 6years old, and for whom birth records were obtained. Concordance between reports was assessed using one-way random intra-class coefficients for continuous measures and kappa coefficients for dichotomous outcomes. Associations between maternal demographic and psychological factors and discrepancies also were tested. Concordance was excellent for continuously measured birthweight (ICC=0.85, pbirth record and absence according to maternal recall. Receipt of public assistance was associated with a decrease in discrepancy in report of nuchal cord. Concordance between maternal retrospective report and medical birth records varies across different types of perinatal events. There was little evidence that demographic or psychological factors increased the risk of discrepancies. Maternal recall based on continuous measures of perinatal factors may yield more valid data than dichotomous outcomes. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    Bleeding is a recognized complication of native percutaneous renal biopsy. This study aimed to describe the incidence of major bleeding after biopsy in a single centre over a 15-year period and examine factors associated with major bleeding. We identified consecutive adult patients undergoing ultrasound-guided native renal biopsy in the Glasgow Renal and Transplant Unit from 2000 to 2014. From the electronic patient record, we collected data pertaining to biopsy indication, pre- and post-biopsy laboratory measurements, prescribed medication and diagnosis. Aspirin was routinely continued. We defined major bleeding post-biopsy as the need for blood transfusion, surgical or radiological intervention or death. Binary logistic regression analysis was used to assess factors associated with increased risk of major bleeding. There were 2563 patients who underwent native renal biopsy (1499 elective, 1064 emergency). The average age of patients was 57 (SD 17) years and 57.4% were male. Overall, the rate of major bleeding was 2.2%. In all, 46 patients required transfusion (1.8%), 9 patients underwent embolization (0.4%), no patient required nephrectomy and 1 patient died as a result of a significant late retroperitoneal bleed. Major bleeding was more common in those undergoing emergency compared with elective renal biopsy (3.4 versus 1.1%; P 30). The risk of major bleeding following native renal biopsy in the modern era is low. Complications are more common when biopsy is conducted as an emergency, which has implications for obtaining informed consent. Our data support the strategy of not stopping aspirin before renal biopsy.

    Full Text Available Objective: To study the effect of bronchoscopic ambroxol lavage on inflammatory factors in lavage fluid of patients with bronchiectasis complicated by infection. Methods: 100 patients with bronchiectasis complicated by infection who were treated in our hospital between May 2012 and January 2016 were divided into the control group (n=54 who received conventional treatment and the observation group (n=46 who received intravenous anti-infection combined with bronchoscopic ambroxol lavage after the therapies were reviewed. The contents of inflammatory factors, adhesion molecules and acute phase proteins in lavage fluid were compared between the two groups. Results: Before treatment, the differences in contents of inflammatory factors, adhesion molecules and acute phase proteins in lavage fluid were not statistically significant between two groups of patients. After treatment, inflammatory factors IL-4, IL-6, IL-10 and TNF-α contents in lavage fluid of observation group were lower than those of control group; adhesion molecules sICAM-1 and VCAM-1 contents in lavage fluid were lower than those of control group; acute phase proteins CRP, AAG, HPT and CER contents in lavage fluid were lower than those of control group. Conclusion: Bronchoscopic ambroxol lavage can reduce airway inflammation in patients with bronchiectasis complicated by infection.

It may have psychological, medical or surgical complications. reporting the incidence of surgical complications of colostomies, their therapeutic management and trying to identify risk factors for their occurrence. A retrospective study for a period of 5 years in general surgery department, Habib Bourguiba hospital, Sfax, including all patients operated with confection of a colostomy. Were then studied patients reoperated for stoma complication. Among the 268 patients who have had a colostomy, 19 patients (7%) developed surgical stoma complications. They had a mean age of 59 years, a sex ratio of 5.3 and a 1-ASA score in 42% of cases. It was a prolapse in 9 cases (reconfection of the colostomy: 6 cases, restoration of digestive continuity: 3 cases), a necrosis in 5 cases (reconfection of the colostomy), a plicature in 2 cases (reconfection of the colostomy) a peristomal abscess in 2 cases (reconfection of the colostomy: 1 case, restoration of digestive continuity: 1 case) and a strangulated parastomal hernia in 1 case (herniorrhaphy). The elective incision and the perineal disease were risk factors for the occurrence of prolapse stomial. Surgical complications of colostomies remain a rare event. Prolapse is the most common complication, and it is mainly related to elective approach. Reoperation is often required especially in cases of early complications, with usually uneventful postoperative course.

    Background The Management of Myelomeningocele Study (MOMS) was a multi-center randomized trial to compare prenatal and standard postnatal closure of myelomeningocele. The trial was stopped early at recommendation of the Data and Safety Monitoring Committee and outcome data for 158 of the 183 randomized women published. Objective In this report, pregnancy outcomes for the complete trial cohort are presented. We also sought to analyze risk factors for adverse pregnancy outcome among those women who underwent prenatal myelomeningocele repair. Study Design Pregnancy outcomes were compared between the two surgery groups. For women who underwent prenatal surgery antecedent demographic, surgical and pregnancy complication risk factors were evaluated for the following outcomes: premature spontaneous membrane rupture on or before 34 weeks 0 days (PPROM), spontaneous membrane rupture at any gestational age (SROM), preterm delivery at 34 weeks 0 days or earlier (PTD) and non-intact hysterotomy (minimal uterine wall tissue between fetal membranes and uterine serosa, or partial or complete dehiscence at delivery) and chorioamniotic membrane separation. Risk factors were evaluated using chi-square and Wilcoxon tests and multivariable logistic regression. Results A total of 183 women were randomized: 91 to prenatal surgery and 92 to postnatal surgery groups. Analysis of the complete cohort confirmed initial findings: that prenatal surgery was associated with an increased risk for membrane separation, oligohydramnios, spontaneous membrane rupture, spontaneous onset of labor and earlier gestational age at birth. In multivariable logistic regression of the prenatal surgery group adjusting for clinical center, earlier gestational age at surgery and chorioamniotic membrane separation were associated with increased risk of SROM (odds ratio [OR] 1.49, 95% confidence interval [CI] 1.01-2.22; OR 2.96, 95% CI 1.05-8.35, respectively). Oligohydramnios was associated with an increased risk

    Purpose: Concurrent chemoradiation therapy (CCRT) is useful in advanced hepatocellular carcinoma (HCC), but little is known about radiation-induced gastroduodenal complications following therapy. To determine risk factors, we investigated the prevalence and patterns of gastroduodenal complications following CCRT using endoscopy. Methods and Materials: Enrolled in the study were 123 patients treated with CCRT for unresectable HCC between January 1998 and December 2005. Radiation-induced gastroduodenal complications were defined as radiation gastritis/duodenitis, radiation gastric/duodenal ulcer, or other gastroduodenal toxicity associated with radiation, based on Common Terminology Criteria for Adverse Events (CTCAE 3.0). Serious gastroduodenal complications were defined as events occurring within 12 months from completion of CCRT, those requiring prompt therapeutic intervention, or symptoms equivalent to Grade 3 or 4 radiation-related gastroduodenal toxicity, including nausea or vomiting, based on CTCAE 3.0. Results: A month after completion of CCRT, 65 (52.8%) patients displayed endoscopic evidence of radiation-induced gastroduodenal complications. Radiation gastric and duodenal ulcers were found in 32 (26.0%) and 20 (16.3%) patients, respectively; radiation gastritis and duodenitis were found in 50 (40.7%) and 42 (34.1%) patients, respectively. Radiation-related bleeding was observed in 13 patients (10.6%). Serious gastroduodenal complications occurred in 18 patients (14.6%) and were significantly more frequent in patients with liver cirrhosis than in those without cirrhosis (p = 0.043). There were no radiation-related deaths. Conclusions: Endoscopically detectable radiation-induced gastroduodenal complications were common in HCC following CCRT. Although serious complications were uncommon, the frequency was higher in patients with liver cirrhosis; thus, these patients should be closely monitored when receiving CCRT.

    spiritual). This study found important relationships between demographic and clinical factors and ostomy complications. Skin problems, leakage, and difficulty adjusting predicted total quality of life scores and domains. Establishing relationships among ostomy complications and demographic, clinical factors, and quality of life can enhance identification of patients at risk for the development of complications and is an important first step in identifying the development of effective interventions to reduce the negative impact of complications for people with ostomies. Further study of predictors and outcomes of ostomy complications is needed to improve care.

    A successful penile prosthesis implantation (PPI) surgery can be defined by outcomes beyond the absence of complications. To introduce the concept of failure to cure (FTC) in the context of PPI to more accurately gauge postoperative outcomes after PPI. Consecutive patients from our sexual function registry who underwent PPI from January 2011 to December 2013 were analyzed. Demographics, previous treatment of erectile dysfunction, comorbidities, social history, postoperative problems (POPs), and surgical outcomes were tabulated. Patients completed the International Index of Erection Function (IIEF) and the Erectile Dysfunction Inventory of Treatment Satisfaction questionnaires. We defined a complication, according to the Clavien-Dindo classification, as any deviation from the ideal postoperative course that is not inherent in the procedure and does not constitute an FTC. FTC was defined as a POP that was not a complication. The χ 2 tests, t-tests, or Wilcoxon rank-sum tests were used. Patient-reported and objective outcomes after PPI. Our enrollment consisted of 185 patients, and we contacted 124 (67%). Of these, 16 (12.9%) had a POP requiring reoperation. Eight patients developed surgical complications (three infections, four erosions, and one chronic pain). Eight patients had FTC (four malpositions and four malfunctions). Factors that correlated with POPs were previous PPI, body mass index higher than 30 kg/m 2 , and previous treatment with intracorporal injections (P .05 for all comparisons). POPs after PPI surgery can be more accurately categorized using the Clavien-Dindo classification of surgical complications to more clearly distinguish surgical complications from FTC. Limitations of our study include its retrospective approach. Our series included a large proportion of patients treated for prostate cancer, which limits the generalizability of our findings. We also had a relatively short median follow-up time of 27 months. Patient-reported outcome

    Evaluation of mandibular reconstructions with free fibula flaps. Identification of factors associated with major recipient site complications, that is, necessitating surgical intervention under general anaesthesia. Seventy-nine reconstructions were included. The following factors were analyzed: fixation type, number of osteotomies, site of defect (bilateral/unilateral), surgeon, sex, ASA classification, continuous smoking, pathological N-stage, age, defect size, flap ischemic time, and postoperative radiotherapy. Proportional hazards regression was used to test the effect on the time between reconstruction and intervention. Sixty-nine (87%) of the 79 fibula flaps were successful at the last follow-up. Forty-eight major recipient site complications occurred in 41 reconstructions. Nineteen complications required surgical intervention within six weeks and were mostly vascular problems, necessitating immediate intervention. These early complications were associated with defects crossing the midline, with an estimated relative risk of 5.3 (CI 1.1-20, P = 0.01). Twenty-nine complications required surgical intervention more than 6 weeks after the reconstruction. These late complications generally occurred after months or years, and were associated with smoking, with an estimated relative risk of 2.8 (CI 1.0-8.3, P = 0.05). Fibula flaps crossing the midline have a higher risk of early major recipient site complications than unilateral reconstructions. Smoking increases the risk of late complications. © 2018 The Authors.

    Full Text Available Context: Type 2 diabetes mellitus (T2DM in young adults is increasing in India. Data on the prevalence of cardiovascular (CV risk factors and complications associated with young-onset T2DM (YOD at the time of diagnosis of diabetes are limited. This data can aid in aggressive diabetes management, CV risk reduction, and prevention of complications. Aim: To determine the prevalence of CV risk factors, micro and macrovascular complications in patients with newly diagnosed YOD. To assess the percentage of patients who require statin therapy based on current American Diabetes Association (ADA guidelines. Settings and Design: This was a retrospective cross-sectional study of 1500 patients with newly detected YOD across seven centers from 2013 to 2015. Designs and Methods: Patients were evaluated for complications of diabetes and CV risk factors such as body mass index (BMI, hypertension, dyslipidemia, and smoking. Statistical Analysis: Measurements have been presented as mean ± standard deviation; results on categorical measurements have been presented in percentages. Results: The mean age, glycated hemoglobin and BMI were 34.7 ± 4.2 years, 9.9 ± 2.4%, and 26.8 ± 4.7 kg/m2. Hypertension, dyslipidemia, BMI >23 kg/m2, and smoking were presented in 27.6%, 62.4%, 84.2%, and 24%. Diabetic retinopathy, neuropathy, and nephropathy were seen in 5.1%, 13.2%, and 0.9%. Ischemic heart disease, peripheral vascular disease, and stroke were presented in 0.7%, 2%, and 0.1%. As per current guidelines, 95.33% needed statin therapy. Conclusion: This study demonstrates that patients with YOD have micro and macrovascular complications at diagnosis. Nearly, every patient required a statin to reduce CV risk. This highlights the importance of screening patients with YOD for CV risk factors and complications of diabetes at the time of diagnosis.

    Pneumothorax is an under-recognized complication of apnea testing performed as part of the neurological determination of death. It may result in hemodynamic instability or even cardiac arrest, compromising ability to declare brain death (BD) and viability of organs for transplantation. We report three cases of pneumothorax with apnea testing (PAT) and review the available literature of this phenomenon. Series of three cases supplemented with a systematic review of literature (including discussion of apnea testing in major brain death guidelines). Two patients were diagnosed with PAT due to immediate hemodynamic compromise, while the third was diagnosed many hours after BD. An additional nine cases of PAT were found in the literature. Information regarding oxygen cannula diameter was available for nine patients (range 2.3-5.3 mm), and flow rate was available for ten patients (mean 11 L/min). Pneumothorax was treated to resolution in the majority of patients (n = 8), although only six completed apnea testing following diagnosis/treatment of pneumothorax and only three patients became organ donors afterward. Review of major BD guidelines showed that although use of low oxygen flow rate (usually ≤ 6 L/min) during apnea testing is suggested, the risk of PAT was explicitly mentioned in just one. Development of PAT may adversely affect the process of BD determination and could limit the opportunity for organ donation. Each institution should have preventive measures in place.

    To meta-analyze complication rate in computed tomography (CT)-guided transthoracic lung biopsy and associated risk factors. Four databases were searched from 1/2000 to 8/2015 for studies reporting complications in CT-guided lung biopsy. Overall and major complication rates were pooled and compared between core biopsy and fine needle aspiration (FNA) using the random-effects model. Risk factors for complications in core biopsy and FNA were identified in meta-regression analysis. For core biopsy, 32 articles (8,133 procedures) were included and for FNA, 17 (4,620 procedures). Pooled overall complication rates for core biopsy and FNA were 38.8 % (95 % CI: 34.3-43.5 %) and 24.0 % (95 % CI: 18.2-30.8 %), respectively. Major complication rates were 5.7 % (95 % CI: 4.4-7.4 %) and 4.4 % (95 % CI: 2.7-7.0 %), respectively. Overall complication rate was higher for core biopsy compared to FNA (p < 0.001). For FNA, larger needle diameter was a risk factor for overall complications, and increased traversed lung parenchyma and smaller lesion size were risk factors for major complications. For core biopsy, no significant risk factors were identified. In CT-guided lung biopsy, minor complications were common and occurred more often in core biopsy than FNA. Major complication rate was low. For FNA, smaller nodule diameter, larger needle diameter and increased traversed lung parenchyma were risk factors for complications. (orig.)

    Gastrointestinal (GI) motility disorders in intensive care patients remain relatively unexplored. Nowadays, the frequency, risk factors and complications of GI dysfunction during enteral nutrition (EN) become more questionable. To evaluate the frequency, risk factors and complications of GI dysfunction during EN in the first 2 weeks of the intensive care unit (ICU) stay and to identify precautions to prevent the development of GI dysfunction and avoid complications. In this prospective observational study, we deliberately targeted at-risk patients. A total of 137 patients who received nasogastric tube feeding in an ICU of a tertiary hospital were enrolled. The incidence of GI dysfunction that was found to be 63% which was associated mainly between MDR bacteria positivity and negative fluid balance. Diarrhea was observed in 36 patients (26%) and on 147 patient-days (incidence rate, 5.5 per 100 patient-days). The median day of diarrhea onset was 6 days after the initiation of EN. Forty patients (29%) presented with constipation (85% during the first week). Fifty patients (36%) exhibited upper digestive intolerance on 212 patient-days (incidence rate, 7.9 per 100 patient-days), after a median EN duration of 6 days (range, 2-14 days). Logistic regression analysis revealed MDR bacteria growth in the culture (OR, 1.75; 95% CI, 1.15-2.67; P =0.008) and negative fluid balance (OR, 0.57; 95% CI, 0.34-0.94; P =0.03) as the risk factors for GI dysfunction. We also showed that GI dysfunction was associated with high SOFA score, hypoalbuminemia, catecholamine use, and prolonged length of stay (LOS). GI dysfunction, on the other hand, can cause some complications including inadequate nutrition, and newly developed decubitus ulcers. GI dysfunction should be considered a clinical predictor of inadequate nutrition and prolonged LOS. In addition, the most dramatic risk for GI dysfunction was observed in patients with MDR bacteria growth in the culture and patients in negative fluid

    Laparoscopic Heller myotomy (LHM) has supplanted an open approach due to decreased operative morbidity. Our goal was to quantify the incidence of peri-operative complications and identify risk factors for adverse outcomes in LHM. All LHM were queried from 2005 to 2011 from the National Surgical Quality Improvement Program database. Adverse outcomes were identified, and univariate and stepwise logistic regression (MVR) was then performed to quantify association. There were 1,237 LHM in the study period. Patient averages were: age 51.9 ± 16.8 years, BMI 27.3 ± 6.6 kg/m(2), Charlson comorbidity index (CCI) 0.2 ± 0.6. 15.3 % had >10 % body mass loss in the preoperative 6 months. During surgery, 10.2 % underwent concomitant EGD, and mean operative time was 141.6 ± 63.4 min. There were 7(0.06 %) wound complications, 22(1.8 %) general complications, and 30(2.4 %) major complications. Average length of stay (LOS) was 2.8 ± 5.5 days. The rate of readmission and reoperation were 3.1 and 2.3 %, respectively, and there were 4(0.03 %) deaths. General and major complications were associated with alcohol use, pack-years of smoking, weight loss, history of stroke, radiation therapy, and longer operative times (p  0.05). Operative time was found to be significantly longer by 35.3 min for inpatients, 43.1 min in functionally dependent patients, 50.0 min in preoperative septic patients, and 17.2 min with concomitant EGD (p < 0.01 for all). LOS was found to be longer by 1.9 days for inpatients, 1.8 days in ASA category ≥3, and 1.2 days per one point increase in CCI (p < 0.001 for all). LHM is being performed nationally with a low incidence of operative complications and mortality. General and major complications following LHM are associated with patient alcohol use, pack-years of smoking, weight loss, history of stroke, radiation therapy, and longer operative times. Additionally, independent predictors of longer operative time and LOS were

    Objective: To study the role of hyperbilirubinaemia as a predictive factor for appendiceal perforation in acute appendicitis. Methods: The prospective, descriptive study was conducted at the Abbasi Shaheed Hospital and the Karachi Medical and Dental College, Karachi, from January 2010 to June 2012. It comprised all patients coming to the surgical outpatient department and emergency department with pain in the right iliac fossa with duration less than seven days. They were clinically assessed for signs and symptoms of acute appendicitis and relevant tests were conducted. Patients were diagnosed as a case of acute appendicitis on the basis of clinical and ultrasound findings, and were prepared for appendicectomy. Per-operative findings were recorded and specimens were sent for histopathology to confirm the diagnosis. SPSS version 10 was used to analyse the data. Results: Of the 71 patients, 37 (52.10%) were male and 34 (47.90%) were female. The age range was 3-57 years, and most of the patients (n=33; 46.5%) were between 11 and 20 years. Besides, 63 (89%) patients had pain in the right iliac fossa of less than four-days duration, while 8 (11%) had pain of longer duration. Total leukocyte count was found to be elevated in 33 (46.5%) patients, while total serum bilirubin was elevated in 41 (57.70%). Ultrasound of abdomen showed 9 (12.70%) patients having normal appearance of appendix and 59 (83.30%) had inflamed appendix. Four (5.60%) patients had no signs of inflammation on naked eye appearance per operatively. Histopathology of appendix showed 10 (14.10%) patients had non-inflammatory appendix. Conclusion: Patients with signs and symptoms of acute appendicitis and a raised total serum bilirubin level indicated a complication of acute appendicitis requiring an early intervention to prevent peritonitis and septicaemia. A raised serum bilirubin level is a good indicator of complicated acute appendicitis, and should be included in the assessment of patients with

    Full Text Available BACKGROUND It is well known that diabetes adversely affects the kidneys finally leading to anaemia by various mechanisms. Several studies had postulated that anaemia developing before renal complications has an independent association with microvascular complication in type 2 diabetic patients. The aim of the study is to estimate the prevalence of anaemia in persons with type 2 diabetes mellitus and its role as a risk factor for the presence and the severity of microvascular complication in a populationbased study. MATERIALS AND METHODS This is a cross-sectional study conducted in patients coming to OPD of the Department of General Medicine in Government Vellore Medical College for a duration of 3 months from June 01, 2016, to August 31, 2016. Type 2 DM patients between the age group 20-60 years attending our diabetic clinic of both sex were included in our study. RESULTS From a total of 100 patients, 41% had anaemia including 34% with normochromic normocytic, 65.85% with hyperchromic microcytic anaemia and none of the patient had macrocytic anaemia. Patients who are anaemic had more frequent microvascular complications. There was no significant difference between males and females. The average duration of diabetes has a positive correlation with anaemia. All the microvascular complications like neuropathy, nephropathy and retinopathy had significant association with the presence of anaemia in type 2 patients. Nephropathy had a significant higher frequency compared to others as a complication in type 2 DM. CONCLUSION Our study shows that there is increased prevalence of anaemia in type 2 DM patients and the prevalence of microvascular complications is significantly higher among the diabetic patients with anaemia.

    Neoadjuvant radiotherapy (RT) for rectal cancer may increase wound complications after oncologic proctectomy. We aimed to assess the relationship between neoadjuvant RT and 30-day wound complications after radical surgery for rectal cancer. We identified rectal cancer patients (International Classification of Diseases, revision-9 [ICD-9] code 154.1) who underwent radical resection, using NSQIP from 2005 to 2010. Patients were stratified into preoperative radiation vs no radiation groups. Our primary outcome was any wound complication. The association between preoperative RT and postoperative wound complication rate was assessed by univariate, multivariable, and propensity score analyses. Of 242,670 colorectal cases, 6,297 patients were included. Of these, 2,476 (39%) received RT within 90 days preoperatively. The RT group, compared with the no RT group, received more chemotherapy within 30 days preoperatively (15.0% vs 2.5%, p return to operating room (6.7% vs 6.7%, p = 0.96), or length of stay (8.4 vs 8.4 days, p = 0.72) between the RT and no RT groups, respectively. The mortality rate in the RT group was lower on univariate analysis (0.7% vs 1.4%, p = 0.008), but was not significantly different in the multivariable analyses. Multivariable and propensity score analyses were consistent with the lack of association between preoperative RT and postoperative wound complications. Neoadjuvant radiotherapy does not appear to be an independent risk factor for wound complications after radical surgery for rectal cancer. Copyright © 2016 American College of Surgeons.

    Full Text Available Objective: Identification of the risk factors and psychological correlates of prolonged grief disorder is vital for health promotions in relatives of persons who died of cancer. The aim of this research was to investigate the role of defense mechanisms, character dimension of personality and demographic factors on complicated grief following a loss of a family member to cancer .Method: A number of 226 persons who had lost a family member to cancer in a cancer institute at Tehran University of Medical Science were selected through compliance sampling and completed the Inventory of complicated Grief-Revised (ICG-R, the Defense Styles Questionnaire (DSQ, the Character dimension of Temperament and Character Inventory (TCI, and the Demographical questionnaire. Data were analyzed by stepwise multiple regression analysis, using the PASW version 18 .Results: Findings revealed that neurotic defense style had a significant positive predictive role in the complicated grief; and cooperativeness, age of the deceased person, self-transcendence and mature defense style had a significant negative predictive role in complicated grief (p<0.001. R2 was 0.73 for the final model (p<.001.Conclusion: The results revealed that two character dimensions (low cooperativeness and self-transcendence, high neurotic defense style and young age of the deceased person were involved in the psychopathological course of the complicated and prolonged grief. It was concluded that personality characteristics of the grieving persons and demographics of the deceased person should be addressed in designing tailored interventions for complicated grief.

    The most effective therapy in patients with limited-stage small cell lung cancer (LS SCLC) seems to be chemotherapy (using platinum-based regimens) and thoracic radiotherapy (TRT), which is followed by prophylactic cranial irradiation. The analysed group comprised 217 patients who received combined treatment for LS SCLC, i.e. chemotherapy (according to cisplatin and etoposide schedule) and TRT (concurrent in 101 and sequential in 116 patients). The influence of chemoradiotherapy (ChT-RT) schedule on treatment results (frequency of complete response, survival rates, and incidence of treatment failure and complications) was evaluated, and the frequency and severity of pulmonary complications were analysed to identify risk factors. The 5-year survival rates in concurrent vs. sequential ChT-RT schedules were 27.3 vs. 11.7% (overall) and 28 vs. 14.3% (disease-free). The frequencies of adverse events in relation to concurrent vs. sequential therapy were 85.1 vs. 9.5% (haematological complications) and 58.4 vs. 38.8% (pulmonary fibrosis), respectively. It was found that concurrent ChT-RT (hazard ratio, HR 2.75), a total dose equal to or more than 54 Gy (HR 2.55), the presence of haematological complications (HR 1.89) and a lung volume receiving a dose equal to or greater than 20 Gy exceeding 31% (HR 1.06) were the risk factors for pulmonary complications. Pulmonary complications after ChT-RT developed in 82% of patients treated for LS SCLC. In comparison to the sequential approach, concurrent ChT-RT had a positive effect on treatment outcome. However, this is a factor that can impair treatment tolerance, which manifests in the appearance of side effects. (orig.) [de

    Objective: To analyze the clinical features and risk factors of cirrhotic patients complicated with infections. Methods: The clinical and laboratory characteristics of cirrhotic patients complicated with infections hospitalized from April 2014 to June 2017 were retrospectively analyzed. Relevant risk factors for infection and mortality were explored. Results: The overall incidence of infections was 17.6% in 1 670 hospitalized cirrhotic patients. Among the recruited 208 patients in this study, alcoholic, viral hepatitis B or C and autoimmune liver diseases accounted for 29.8% (62/208), 26.0% (54/208), and 22.1% (46/208), respectively. The most common infection site was respiratory tract (70.2%), followed by urinary tract, intestinal and intra-abdomen. Forty-six pathogens were isolated from 32 patients, including 22 (47.8%) Gram negative bacteria, 16 (34.8%) Gram positive bacteria and 2(4.3%) mycobacterium tuberculosis, 5 (10.9%) fungi and 1 (2.2%) mycoplasma. The mortality in patients with nosocomial infections (16.7%,7/42) was higher than that in patients with community-acquired infections (6.0%,10/166, P =0.025). All 17 deaths occurred in decompensated cirrhosis. Multivariate analysis demonstrated that hepatic encephalopathy and prothrombin time were independent risk factors of mortality. Conclusions: Patients with decompensated cirrhosis are more susceptible to infections. Hepatic encephalopathy and prothrombin time are independent risk factors for death.

    Summary Background Recent developments in hip arthroscopic techniques and technology have made it possible in many cases to avoid open surgical dislocation for treating a variety of pathology in the hip. Although early reports suggest favourable results’ using hip arthroscopy and it has been shown to be a relatively safe procedure, complications do exist and can sometimes lead to significant morbidity. Methods This is a review article. The aim of this manuscript is to present the most frequent and/or serious complications that could occur at or following hip arthroscopy and some guidelines to avoid these complications. Conclusion Most complications of hip arthroscopy are minor or transient but serious complications can occur as well. A lot of complication e.g. acetabular labral puncture go unreported. Appropriate education and training, precise and meticulous surgical technique with correct instrumentation, the right indication in the right patient and adherence to advice from mentors and experienced colleagues are all essential factors for a successful outcome.

    Full Text Available Background: Liver dysfunction during on-pump coronary artery bypass graft surgery (CABG is a rare complication but is associated with significant morbidity and mortality. The ability to identify high-risk patients may be helpful in planning appropriate management strategies. We aimed to evaluate the factors influencing liver function tests during on-pump CABG. Methods: In 146 patients scheduled for on-pump CABG, the liver function test was done preoperatively and on the first postoperative day. Some preoperative and intraoperative risk factors were checked and then the postoperative liver function tests were compared with the preoperative ones. Probable relationships between these changes and the preoperative and intraoperative risk factors were studied. Results: A medical history of diabetes had a significant relationship with the changes in direct bilirubin. Preoperative central venous pressure had a significant relationship with the changes in aspartate aminotransferase and alanine aminotransferase. Use of intra-aortic balloon pump and duration of aortic cross-clamp were significantly related to the changes in the liver function tests except for alanine aminotransferase and alkaline phosphatase. Conclusion: It seems that the techniques for the reduction of cardiopulmonary bypass and aortic cross-clamp duration may be useful to protect liver function. We recommend that a larger population of patients be studied to confirm these findings.

    2014-12-01

    Full Text Available Liver complications in haemoglobinopathies (thalassaemia and sickle cell disease are due to several factors, dominated (beside chronic viral infections, not considered here by chronic iron overload, biliary obstruction and venous thrombosis. Whereas the latter two factors can cause acute hepatic syndromes, all three mechanisms - when becoming chronic- can produce fibrosis and cirrhosis and even, in thalassaemia, hepatocellular carcinoma. These chronic hepatic complications are an indirect consequence of the significant improvement in life expectancy due to the overall amelioration of disease management. The diagnostic approach has benefited from non invasive (biochemical and imaging approaches which have considerably reduced the indication of liver biopsy. The therapeutic management involves relatively efficient curative medical, endoscopic or surgical methods, but should rest primarily on preventive measures focused on the haematological causative factors but also on hepatic co-morbidities. This chapter will focus on hepatic complications in thalassaemia and sickle cell disease (SCD, without considering the complications related to virus B or C infections which will be described in another chapter.

    Surgery on renal tumours with venous thrombosis suffers a high rate of complications and non-negligible perioperative mortality. Our objective was to analyse the postoperative complications, their relationship with the level of the thrombus and its potential predisposing factors. A retrospective analysis was conducted of 101 patients with renal tumours with venous thrombosis operated on between 1988 and 2017. Two patients were excluded because of intraoperative pulmonary thromboembolism and exitus (2%). The postsurgical complications were classified according to Clavien-Dindo. To compare the qualitative variables, we employed the chi-squared test. We performed a multivariate analysis using binary logistic regression to identify the independent predictors. Some type of postsurgical complication occurred in 34 (34.3%) patients, 11 (11.1%) of which were severe (Clavien III-V). There were significant differences in the total complications (P=.003) and severe complications (Clavien≥III; P=.03) depending on the level of the tumour thrombus. Copyright © 2018 AEU.

    The purpose of this study was to evaluate the psychometric properties of a new instrument to measure incidence and severity of ostomy complications early in the postoperative period. 71 participants were enrolled, most were men (52%), white (96%), and married or partnered (55%). The mean age of participants was 57 ± 15.09 years (mean ± SD). Fifty-two participants (84%) experienced at least 1 ostomy complication in the 60-day postoperative period. The research setting was 3 acute care settings within a large healthcare system in the Midwestern United States. We developed an evidence-based conceptual model to guide development and evaluation of a new instrument, the Pittman Ostomy Complication Severity Index (OCSI). The OCSI format includes Likert-like scale with 9 individual items scored 0 to 3 and a total score computed by summing the individual items. Higher scores indicate more severe ostomy complications. This study consisted of 2 phases: (1) an expert review, conducted to establish content validity; and (2) a prospective, longitudinal study design, to examine psychometric properties of the instrument. A convenience sample of 71 adult patients who underwent surgery to create a new fecal ostomy was recruited from 3 hospitals. Descriptive analyses, content validity indices, interrater reliability testing, and construct validity testing were employed. Common complications included leakage (60%), peristomal moisture-associated dermatitis (50%), stomal pain (42%), retraction (39%), and bleeding (32%). The OCSI demonstrated acceptable evidence of content validity index (CVI = 0.9) and interrater reliability for individual items (k = 0.71-1.0), as well as almost perfect agreement for total scores among raters (ICC = 0.991, P ≤ .001). Construct validity of the OCSI was supported by significant correlations among variables in the conceptual model (complications, risk factors, stoma care self-efficacy, and ostomy adjustment). OCSI demonstrated acceptable validity and

    Full Text Available Mechanical ventilation of the lungs, as an important therapeutic measure, cannot be avoided in critically ill patients. However, when machines take over some of vital functions there is always a risk of complications and accidents. Complications associated with mechanical ventilation can be divided into: 1 airway-associated complications; 2 complications in the response of patients to mechanical ventilation; and 3 complications related to the patient’s response to the device for mechanical ventilation. Complications of artificial airway may be related to intubation and extubation or the endotracheal tube. Complications of mechanical ventilation, which arise because of the patient’s response to mechanical ventilation, may primarily cause significant side effects to the lungs. During the last two decades it was concluded that mechanical ventilation can worsen or cause acute lung injury. Mechanical ventilation may increase the alveolar/capillary permeability by overdistension of the lungs (volutrauma, it can exacerbate lung damage due to the recruitment/derecruitment of collapsed alveoli (atelectrauma and may cause subtle damages due to the activation of inflammatory processes (biotrauma. Complications caused by mechanical ventilation, beside those involving the lungs, can also have significant effects on other organs and organic systems, and can be a significant factor contributing to the increase of morbidity and mortality in critically ill of mechanically ventilated patients. Complications are fortunately rare and do not occur in every patient, but due to their seriousness and severity they require extensive knowledge, experience and responsibility by health-care workers.

    Cranioplasties are an important neurosurgical procedure not only for improved cosmesis but also for improved functional recovery after craniectomy with a large cranial defect. The aim of this study was to identify predictive factors of postcranioplasty complications using custom-made porous hydroxyapatite cranioplasty. Retrospective review was performed of all patients who underwent a reconstructive cranioplasty using custom-made hydroxyapatite at our institution between February 2008 and September 2017. Postoperative complications considered included bacterial infection, seizures, hydrocephalus requiring ventricular shunt placement, and cranioplasty-to-bone shift. Variables associated at P < 0.1 level in unadjusted analysis were entered into backward stepwise logistic regression models. Of 109 patients included, 15 (13.8%) experienced postoperative infection, with craniectomy performed at an outside institution (adjusted odds ratio [OR] 10.37 [95% confidence interval [CI], 2.03-75.27], P = 0.012) and a previous infection at the surgical site (adjusted OR 6.15 [95%CI, 1.90-19.92], P = 0.003) identified as independent predictors. Six patients (5.5%) experienced postoperative seizures, with stroke (ischemic and hemorrhagic) as a reason for craniectomy (adjusted OR 11.68 [95% CI, 2.56-24.13], P < 0.001) and the presence of seizures in the month before cranioplasty (adjusted OR 9.39 [95% CI, 2.04-127.67], P = 0.002) identified as independent predictors. Four patients (3.7%) experienced postcranioplasty hydrocephalus necessitating shunt placement, and 5 patients (4.6%) experienced cranioplasty-to-bone shift ≥5 mm, but no significant predictive factors were identified for either complication. This study identified possible predictive factors for postcranioplasty complications to help identify at-risk patients, guide prophylactic care, and improve morbidity of this important surgical procedure.

    The aim of this study was to determine the effect of established risk factors on the outcome of secretin pancreatic function testing (sPFT) in patients undergoing work-up for suspected chronic pancreatitis. We completed a retrospective review of patients who underwent sPFT for suspected chronic pancreatitis over 20 years. We compared peak bicarbonate concentrations between groups and completed univariate and multivariate analyses to determine associations between risk factors and positive sPFT results (peak bicarbonate pancreatitis (RAP) and with local complications from acute pancreatitis (AP) (P ≤ 0.05). The bicarbonate concentration in patients with and without other risk factors such as tobacco use, alcohol use, and family history of pancreatitis was not significantly different. Female sex, a history of AP, and a history of RAP were associated with positive sPFT results on univariate analysis (P ≤ 0.05). On multivariate analysis, sex and RAP remained significant. Our study demonstrates that female sex, history of AP and RAP, and AP with local complications are associated with positive sPFT results or lower peak bicarbonate concentration. However, other risk factors do not impact the results of sPFT.

    Full Text Available ABSTRACT Introduction: In patients with mechanical prosthetic heart valves or atrial fibrillation requiring anticoagulation to prevent thromboembolic events, several factors influence adherence and anticoagulation complications. Objective: To evaluate the factors that interfere with the quality and complications of anticoagulation with vitamin K antagonists. Methods: A retrospective cohort study of 100 patients, in the period from 2011 to 2014, was performed. Anticoagulation conditions in the last year, regarding the presence of complications (embolisms/bleeding and inadequate treatment were assessed: achievement of less than 8 annual prothrombin times and International Normalized Ratio outside therapeutic target in more than 40% of prothrombin times. Results: There were 31 complications (22 minor bleeding without hospitalization and 9 major complications: 7 bleeding with hospitalization and two emboli; 70 were with International Normalized Ratio outside the target in more than 40% of the tests and 36 with insufficient number of prothrombin times. Socioeconomic factors, anticoagulant type and anticoagulation reason had no relationship with complications or with inadequate treatment. There were more complications in patients with longer duration of anticoagulation (P=0.001. Women had more International Normalized Ratio outside the target range (OR 2.61, CI:1.0-6.5; P=0.04. Patients with lower number of annual prothrombin times had longer times of anticoagulation (P=0.03, less annual consultations (P=0.02 and less dose adjustments (P=0.003. Patients with longer duration of anticoagulation have more complications (P=0.001. Conclusion: There was a high rate of major complications and International Normalized Ratio was outside the goal. Less annual prothrombin times was related to longer duration of anticoagulation, less annual consultations and less dose adjustments. More major complications occurred in patients with longer duration of

    To investigate whether prepregnancy overweight in women with epilepsy increases their risk for complications during pregnancy and delivery. This study is based on The Norwegian Mother and Child Cohort Study (MoBa) linked to the Medical Birth Registry of Norway. A diagnosis of epilepsy was reported in 706 pregnancies. Overweight was defined as body mass index ≥ 25 prepregnancy. Overweight women with epilepsy (n = 259) were compared to normal-weight women with epilepsy (n = 416), and to women without epilepsy with and without overweight (n = 30,516 and n = 67,977, respectively). The risks of pregnancy and delivery complications were calculated as odds ratios (ORs) with 95% confidence intervals (CIs) adjusted for adverse socioeconomic factors, age, parity, and smoking. Women with epilepsy were more often overweight than women without epilepsy (38.4% vs. 31.3%, p < 0.001). The majority of pregnancy and delivery complications were more frequent in overweight women with epilepsy. Compared to overweight women without epilepsy, the risk was increased for cesarean section (OR 1.6, CI 1.2-2.2, p < 0.001), excessive bleeding (OR 1.4, CI 1.0-1.8, p = 0.04), peripartum anxiety and depressive symptoms (OR 1.9, CI 1.3-2.8, p < 0.001), small for gestational age children (OR 2.4, CI 1.2-4.8, p = 0.02), and transfer of the infant to a neonatal ward (OR 1.5, CI 1.1-2.2, p = 0.02). Compared to normal-weight women with epilepsy, the risk of cesarean section (OR 1.6, CI 1.1-2.3, p < 0.05), gestational hypertension (OR 2.0, CI 1.1-3.5, p < 0.05), preeclampsia (OR 2.3, CI 1.2-4.5, p < 0.05), and transfer of the infant to a neonatal ward (OR 2.2, CI 1.3-3.6, p < 0.01) was increased. Prepregnancy overweight in combination with epilepsy entails a strong negative effect on risk of complications during pregnancy and delivery. In women with epilepsy and overweight referral to a nutritionist should be considered when an antiepileptic drug is started as well as

    Full Text Available The main goal of this study is to identify the role of compliance in the prevention of complications while wearing soft contact lenses (SCL. 2257 patients in the «Center of vision correction contact» were examined. The age of patients was from12 till 46 years. 58 % female, 42 % male. 47.5 % patients were using daily disposable lenses, 52.5 % — lenses of planned replacement: 23.4 % — 2 weeks, 25.1 % — 1 month, 4 % — 3 months. All patients were using SCL for at least 1 year. The benefits of contact lens are compared with the glasses by different authors. However, any contact lens are a foreign body for the eye, which requires special care, and in case of non-compliance with the doctor’s recommendations may cause the complications. This study has shown that compliance among patients using contact lenses is below 50 %. The main reason for noncompliance of patients is the lack of time and attention to the health of patients. For achievement of compliance and prevention of complications of contact lens is recommended to regularly take the following necessary measures: patient education, explaining to him the need for each stage of lens care, which increases motivation. At the same time, the learning process can be demonstrated to have complications arise in the case of disturbances. Optimization of individual therapeutic program, which is the correct selection of contact lenses and care products tailored to the individual needs of the patient, his lifestyle and personal finance. However, the risk of complications depends not only on the doctor or the manufacturer, but to a greater extent on the patient. In other words, compliance — a necessary condition for ensuring the effectiveness of contact lens and avoiding the occurrence of complications.

    Strictureplasty (SP) or miniresective 'bowel-sparing' techniques (MR) can prevent the risk of intestinal stomia and short bowel syndrome in patients affected by Crohn's disease (CD). The aim of this study was to analyze the perioperative morbidity and mortality in 104 of 138 consecutive patients treated for CD complications using bowel-sparing techniques. We also considered the factors that may be related to the risk of perioperative complications and the long-term outcome. One hundred and four patients were treated with SP and/or MR and then included in a prospectively maintained database. The factors claimed to influence perioperative complications were analyzed using Fisher's exact test for categorical observations and the Mann-Whitney U test for continuous variables. A multivariate analysis, using logistic regression, and a long-term time-to-event analysis using the Kaplan-Meier function, were also performed. Perioperative mortality was nil. In relation to the 6 postoperative complications (5.8%), 4 patients underwent minimal bowel resection (MR), 1 a MR with SP, and 1 SP alone. Three of these patients (2.9%) needed reoperation for septic complications, and 3 (2.9%) were treated as outpatients for enterocutaneous fistulas. A correlation (p < 0.05) was found between low serum hemoglobin levels and postoperative complications at univariate and multivariate analyses. The 5-year surgical recurrence-free rate was 75% overall, 73% for patients treated with SP, 78% with MR, and 77% with MR + SP. Postoperative complications are not related to conservative or miniresective surgery even when active disease is present at the resection margins or the site of SP. The higher risk reported for patients with low serum hemoglobin and hematocrit levels suggests that surgeons should consider using preoperative iron and vitamin support, parenteral nutrition and erythropoietin therapy, when necessary, in those cases. Our postoperative morbidity, mortality and long-term surgical

    Conclusions: Large glandular specimen increases the risk of NAC necrosis. The degree of ptosis and the distance between the sternal notch and the NAC have no significant impact on necrotic complications in NSM. To reduce the necrotic complications in large breast after NSM, reconstruction should better be performed with autologous flap or slow skin expansion using the expander technique.

    Anorectal complications are common in patients with haematological malignancies. The objectives are to characterize anorectal complications in these patients, identify risk factors and shed light on treatment, morbidity and mortality rates. A retrospective, observational study that included 83 inpatients with haematological malignancies and proctological symptoms from January 2010 to September 2015 was conducted. Clinical outcomes were obtained through a detailed review of medical records. The median age was 56 years, and 52 (62.7%) patients were men. Fifty-six (67.5%) patients had nonseptic anorectal complications and 27 (32.5%) patients had septic anorectal complications. Patients with septic anorectal complications were more commonly male, older, and had lower absolute neutrophil counts, but the differences were not statistically significant (P=0.79, 0.67 and 0.89, respectively). In positive blood cultures [23/70 (32.9%)], Enterococcus faecium, Klebsiella pneumonia, and Escherichia coli were the most common isolated agents. In nonseptic anorectal complications, conservative treatments/minor proctological procedures were adopted, and patients with septic anorectal complications were treated with antibiotics±major proctological procedures and/or surgical drainage/debridement. Forty-eight (85.7%) patients in the nonseptic complications group improved compared with 23 (85.2%) patients in the septic complications group. The overall mortality rate was 2.4% (n=2), with one (1.2%) death related to perianal sepsis. Enterococcus spp. were more commonly identified in this study and can be increasing in this specific population. In contrast to other reports, we did not identify an association between septic anorectal complications and possible risk factors such as male sex, younger age or a low absolute neutrophil count. Most patients had nonseptic anorectal complications. A major proctological procedure/surgical debridement should always be applied in septic complications

    The decreased placental perfusion is the underlying reason for intrauterine growth restriction that in turn leads to reduced placental perfusion and ischemia. However, there are several issues to be understood in the pathophysiology of intrauterine growth restriction. We aimed to study whether any compensatory response in placental vascular bed occur in pregnancies complicated with intrauterine growth restriction by the immunohistochemical staining of von Willebrand factor and caldesmon in placental tissues. A total of 103 pregnant women was enrolled in the study including 50 patients who were complicated with IUGR and 50 uncomplicated control patients. The study was designed in a prospective manner. All placentas were also stained with von Willebrand factor and caldesmon monoclonal kits. The immunohistochemical staining of von Willebrand factor and caldesmon expressions in placental tissues were different between normal and intrauterine growth restriction group. The percentages of 2+ and 3+ von Willebrand factor expression were higher in the intrauterine growth restriction group comparing with the normal group, although the difference was not statistically significant. The intensity of caldesmon expression was significantly lower in the intrauterine growth restriction group in comparison with the normal group (p intrauterine growth restriction which is a hypoxic condition. But newly formed vessels are immature and not strong enough. Our study is important to clarify the pathophysiology and placental compensatory responses in intrauterine growth restriction.

    Sarcopenia is an independent risk factor for adverse outcomes in critically ill patients. The impact of sarcopenia on morbidity and length of stay in a trauma population has not been completely defined. This project evaluated the influence of sarcopenia on patients admitted to the trauma service. A retrospective review of 778 patients presenting as a trauma alert at a single institution from 2012-2014 was completed. Records were abstracted for comorbidities and hospital complications. The Hounsfield Unit Area Calculation was collected from admission computed tomography scans. Criteria for sarcopenia were based on the lowest 25th percentile of muscle density measurements. Relationships to patient outcomes were evaluated by univariate and multivariable regression or analyses of variance, when applicable. A total of 432 (55.6%) patients suffered a complication. Sarcopenia was associated with overall complications (P sarcopenia into a novel length of stay calculator showed increased prognostic ability for prolonged length of stay over Abbreviated Injury Scale alone (P = 0.0002). Sarcopenia is an independent risk factor for adverse outcomes and increased length of stay in trauma patients. Prognostic algorithms incorporating sarcopenia better predict hospital length of stay. Identification of patients at risk may allow for targeted interventions early in the patient's hospital course. Copyright © 2017 Elsevier Inc. All rights reserved.

    A number of acute oral complications may be associated with cancer therapy in children, but the extent and duration of these complications, and the most effective management techniques. have not been well described. The few studies differ in design, making comparisons difficult. Well-controlled, prospective clinical studies are needed to define the most effective strategies for the management of acute oral complications in children. However, it is clear that dental intervention prior to cancer therapy is an important factor in the optimal preparation of the patient. During cancer therapy, intensive supervised oral preventive protocols appear to be of benefit to the child's oral health, overall comfort, and well-being. Furthermore, the prevention of oral infection may significantly reduce the morbidity associated with cancer therapy. Long-term preventive oral care may help prevent dental disease and infection in medically compromised children and contribute to improving the quality of life. 41 references

    The Sewol ferry disaster caused shock and grief in South Korea. The aim of this study was to identify the factors associated with symptoms of complicated grief (CG) among the surviving students 20 months after that disaster. This study was conducted using a cross-sectional design and a sample of 57 students who survived the Sewol ferry disaster. Data were collected using the following instruments: Inventory of Complicated Grief (ICG), the Lifetime Incidence of Traumatic Events-Child, the Child Report of Post-Traumatic Symptoms (CROPS), KIDSCREEN-27, Family Adaptability and Cohesion Evaluation Scales-III, the Peri-traumatic Dissociation-Post-traumatic Negative Beliefs-Post-traumatic Social Support scale, and the Strengths and Difficulties Questionnaire. A generalized linear model using a log link and Poisson distribution was performed to identify factors associated with symptoms of CG. The mean score on the ICG was 15.57 (standard deviation: 12.72). Being born in 1999, a higher score on the CROPS and a lower score in autonomy and relationship with parents on the KIDSCREEN-27 were related to higher levels of CG. Twenty months after the Sewol ferry disaster, 24.5% of surviving students were suffering from CG. This study uncovered a vulnerable population of bereaved children at high risk for CG.

    Full Text Available Modern surgery is faced with the emergence of newer “risk factors” and the challenges associated with identifying and managing these risks in the perioperative period. Obstructive sleep apnea and obesity hypoventilation syndrome pose unique challenges in the perioperative setting. Recent studies have identified some of the specific risks arising from caring for such patients in the surgical setting. While all possible postoperative complications are not yet fully established or understood, the prevention and management of these complications pose even greater challenges. Pulmonary hypertension with its changing epidemiology and novel management strategies is another new disease for the surgeon and the anesthesiologist in the noncardiac surgical setting. Traditionally most such patients were not considered surgical candidates for any required elective surgery. Our review discusses these disease entities which are often undiagnosed before elective noncardiac surgery.

    Full Text Available Introduction: Complications associated with blood donation significantly lower odds of subsequent donations. The aim of the study is to assess the prevalence of complications related to blood donation, identify the influencing factors, and come up with suggestions for minimizing discomfort to donors and making outdoor voluntary blood donation camps safer. Materials and Methods: This study covered 181 blood donation camps organized by Sankalp India Foundation where 16 blood banks participated from 01-04-2011 to 01-08-2014 in Karnataka. Uniform protocols for donor selection, predonation preparation, counseling, postdonation care, and refreshments were used. The postdonation complications were recorded on a form immediately, after they were observed. Results: We observed 995 (3.2% complications in 30,928 whole blood donations. Of these 884 (2.86% mild, 77 (0.25% moderate, and 5 (0.02% severe complications were observed. Local symptoms (blood outside vessels, pain, and allergy contributed 1.0%, and generalized symptoms (vasovagal reaction contributed 2.2% to all the complications. Conclusion: We observed 322 complications for every 10,000 donations. Since 27 out of every 10000 experience moderate and severe complication, the readiness to manage complications is crucial. Women donors, young donors, and donors with a lower weight are at a significantly greater risk of experiencing complications, highlighting the need for specific guidelines for the management of higher risk donor groups. Complications varied significantly between various blood banks. Predonation hydration was effective in limiting complications with generalized symptoms. We recommend a robust donor hemovigilance program for voluntary blood donation for monitoring complications and enable assessment of effectiveness and implementation of appropriate interventions.

    First-time donation is among recognised risk factors for vasovagal reactions to blood donation and reactions are known to reduce donor return. We assessed associations between potential risk factors and vasovagal reactions and needle-related complications in first-time whole blood donation in comparison to repeat donation and analysed the impact of complications on donor return. We performed a cohort study on whole blood donations in The Netherlands from 1/1/2010 to 31/12/2010 using data extracted from the blood service information system. Donation data up to 31/12/2011 were used to ascertain donor return. In 2010 28,786 donors made first whole blood donations and there were 522,958 repeat donations. Vasovagal reactions occurred in 3.9% of first donations by males and 3.5% of first donations by females compared to in 0.2% and 0.6%, respectively, of repeat donations. Associations of vasovagal reactions with other factors including age, body weight, systolic and diastolic blood pressure were similar in first-time and repeat donors. Needle-related complications occurred in 0.2% of male and 0.5% of female first-time donations and in 0.1% and 0.3%, respectively, of repeat donations. Among first-time donors, the return rate within 1 year was 82% following an uncomplicated first donation, but 55% and 61% following vasovagal reactions and needle-related complications, respectively; the corresponding percentages among repeat donors were 86%, 58% and 82%. Among first-time donors, females suffered less than males from vasovagal reactions. Other risk factors had similar associations among first-time and repeat donors. Vasovagal reactions and needle-related complications in both first-time and repeat donors are followed by reduced donor return.

    To evaluate risk factors associated with death and development of perioperative complications in dogs undergoing surgery for treatment of gastric dilatation-volvulus (GDV). Retrospective case series. 166 dogs. Records of dogs with confirmed GDV that underwent surgery were reviewed. Logistic regression was performed to identify factors associated with development of complications (ie, hypotension, arrhythmias, gastric necrosis necessitating gastrectomy, disseminated intravascular coagulation, peritonitis, sepsis, postoperative dilatation, postoperative vomiting, and incisional problems) and with short-term outcome (ie, died vs survived to the time of suture removal). Short-term mortality rate was 16.2% (27/166). Risk factors significantly associated with death prior to suture removal were clinical signs for > 6 hours prior to examination, combined splenectomy and partial gastrectomy, hypotension at any time during hospitalization, peritonitis, sepsis, and disseminated intravascular coagulation. Partial gastrectomy was not a significant risk factor for death but was for peritonitis, disseminated intravascular coagulation, sepsis, and arrhythmias. Age, gastrectomy, and disseminated intravascular coagulation were risk factors for development of hypotension. Use of a synthetic colloid or hypertonic saline solution was associated with a significantly decreased risk of hypotension. Results suggest that the prognosis for dogs undergoing surgery because of GDV is good but that certain factors are associated with an increased risk that dogs will develop perioperative complications or die.

    Full Text Available Liver transplantation is an effective treatment for end-stage chronic liver diseases and acute liver failure. With the rapid development of surgical techniques, organ preservation technology, and pharmacotherapy, patients' survival rates are improved constantly. However, postoperative complications are still major influencing factors for postoperative incidence and mortality rates. Since clinical and laboratory examinations lack specificity and it is difficult to diagnose various postoperative complications, the application of imaging techniques effectively solves such problems. This article summarizes the imaging findings of common complications after liver transplantation, such as vascular complications, biliary complications, liver parenchyma lesions, and postoperative infection, and points out that imaging examinations have significant advantages and can be used for comprehensive evaluation of disease progression.

    To investigate the 30-day postoperative adverse event (AE) rates of adults 60 years or older after shoulder arthroscopy and identify risk factors for complications in this patient population. Patients aged 60 or more who underwent shoulder arthroscopy were identified in the American College of Surgeons National Surgery Quality Improvement Program database from 2006 to 2013 using 12 Current Procedural Terminology codes related to shoulder arthroscopy. Complications were categorized as severe AEs, minor AEs, and infectious AEs for separate analyses. Pearson's χ 2 tests were used to identify associations between patient characteristics and AE occurrence and binary logistic regression for multivariate analysis of independent risk factors. In total, 7,867 patients were included for analysis. Overall, 1.6% (n = 127) of the older adults experienced at least one AE with 1.1% (n = 90) severe AEs, 0.6% (n = 46) minor AEs, and 0.4% (n = 28) infectious complications. Multivariate analysis revealed that age 80 years or older (odds ratio [OR] = 2.2, 95% confidence interval [CI] = 1.2-2.7, P = .01), body mass index greater than 35 (OR = 1.8, 95% CI = 1.1-2.7, P = .01), functionally dependent status (OR = 2.9, 95% CI = 1.3-6.8, P = .01), American Society of Anesthesiologists class greater than 2 (OR = 1.5, 95% CI = 1.0-2.2, P = .04), congestive heart failure (OR = 6.1, 95% CI = 1.8-21.2, P = .03), disseminated cancer (OR = 7.9, 95% CI = 1.4-43.9, P = .02), and existence of an open wound at the time of surgery (OR = 4.0, 95% CI = 1.1-14.6, P = .03) were independently associated with the occurrence of an AE. Nineteen of the patients included in the study required readmission to the hospital within the 30-day period for an overall readmission rate of 0.2%. Patients 60 years or older who underwent shoulder arthroscopy for a variety of indications have a low overall 30-day postoperative complication rate of 1.6%. Although low, this is a higher rate than

    Full Text Available Abstract Background Stress echocardiography is a cost-effective tool for the modern noninvasive diagnosis of coronary artery disease. Several physical and pharmacological stresses are used in combination with echocardiographic imaging, usually exercise, dobutamine and dipyridamole. The safety of a stress is (or should be a major determinant in the choice of testing. Although large scale single center experiences and multicenter trial information are available for both dobutamine and dipyridamole stress echo testing, complications or side effects still can occur even in the most experienced laboratories with the most skilled operators. Case presentation We decided to present a case collection of severe complications during pharmacological stress echo testing, including a ventricular tachycardia, cardiogenic shock, transient ischemic attack, torsade de pointe, fatal ventricular fibrillation, and free wall rupture. Conclusion We believe that, in this field, every past complication described is a future complication avoided; what happens in your lab is more true of what you read in journals; and Good Clinical Practice is not "not having complications", but to describe the complications you had.

    Full Text Available Marine omega-3 polyunsaturated fatty acids (n-3 PUFA are important nutrients during periods of rapid growth and development in utero and infancy. Maternal health and risk factors play a crucial role in birth outcomes and subsequently offspring cardio-metabolic health. Evidence from observational studies and randomized trials have suggested a potential association of maternal intake of marine n-3 PUFAs during pregnancy with pregnancy and birth outcomes. However, there is inconsistency in the literature on whether marine n-3 PUFA supplementation during pregnancy can prevent maternal complications of pregnancy. This narrative literature review summarizes recent evidence on observational and clinical trials of marine n-3 PUFA intake on maternal risk factors and effects on offspring cardio-metabolic health. The current evidence generally does not support a role of maternal n-3 PUFA supplementation in altering the incidence of gestational diabetes, pregnancy-induced hypertension, or pre-eclampsia. It may be that benefits from marine n-3 PUFA supplementation are more pronounced in high-risk populations, such as women with a history of complications of pregnancy, or women with low marine n-3 PUFA intake. Discrepancies between studies may be related to differences in study design, dosage, fatty acid interplay, and length of treatment. Further prospective double-blind studies are needed to clarify the impact of long-chain marine n-3 PUFAs on risk factors for cardio-metabolic disease in the offspring.

    Obesity usually is associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause (eg, nonalcoholic fatty liver disease) or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease, erosive esophagitis, Barrett’s esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including nonalcoholic fatty liver disease, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer. Gastroenterologists are uniquely poised to participate in the multidisciplinary management of obesity as physicians caring for people with obesity-related diseases, in addition to their expertise in nutrition and endoscopic interventions.

    Background: Emergency cesarean section done in advanced labor is a big challenge in obstetrics due to increased risk of intraoperative complications. In the last decade, a rapid increase in cesarean section done in advanced labor has been observed. Difficult deli-very of the fetal head during cesarean section carries a high risk of intraoperative complications like cervical and uterine tears, intra operative hemorrhage and trauma to the baby. Objectives: The purpose of this study is to find out the frequency and risk factors for intra-operative complications in emergency cesarean section done in advanced labor, so that appropriate management protocols can be planned to reduce these complications. Study Design: Prospective cohort study. Materials and Methods: This prospective study was carried out in Obstetrics and Gynecology Unit - 2 of Services Institute of Medical Sciences, Services Hospital, Lahore; from 1st January 2007 to 31st December 2007. All patients undergoing emergency cesarean sections done on laboring mothers were included in the study. The sample was divided into two groups; emergency C-section done in advanced labor as the study group and emergency C-section in early labor as the control group. Data were collected regarding age, parity, booked or unbooked status, indications for cesarean section, level of competence of operating surgeon, intra-operative complications and the risk factors for these complications. Data were recorded on a structured proforma and compared between the two groups. Statistical Analysis: Data were analyzed using computer programme SPSS Version 14 for windows applying student t-test for quantitative and chai square test for qualitative parameters. A p-value < 0.05 was used as statistically significant. Results: Out of 2064 total deliveries in the year 2007, 1290 (62.5%) were vaginal deliveries and 774 (37.5%) were C-Sections. Out of 774 C-Section, 174 (23%) were elective and 600 (77%) were emergency. Out of 600 emergency C

    Sedation practices for gastrointestinal endoscopic (GIE) procedures vary widely in different countries depending on health system regulations and local circumstances. The goal of procedural sedation is the safe and effective control of pain and anxiety, as well as to provide an appropriate degree of memory loss or decreased awareness. Sedation-related complications in gastrointestinal endoscopy, once occurred, can lead to significant morbidity and occasional mortality in patients. The risk factors of these complications include the type, dose and mode of administration of sedative agents, as well as the patient's age and underlying medical diseases. Complications attributed to moderate and deep sedation levels are more often associated with cardiovascular and respiratory systems. However, sedation-related complications during GIE procedures are commonly transient and of a mild degree. The risk for these complications while providing any level of sedation is greatest when caring for patients already medically compromised. Significant unwanted complications can generally be prevented by careful pre-procedure assessment and preparation, appropriate monitoring and support, as well as post-procedure management. Additionally, physicians must be prepared to manage these complications. This article will review sedation-related complications during moderate and deep sedation for GIE procedures and also address their appropriate management.

    There has been a thrilling development , as well as profound changes, in our understanding of the effect of fetal nutrition on the development and health of the child. The Norwegian Mother and Child Cohort Study (MoBa) is an ongoing nationwide population-based pregnancy cohort study that between 1999 and 2008 recruited 90,723 women with 106,981 pregnancies and 108,487 children. The objective of MoBa is to test specific etiologic hypotheses by estimating the association between exposures and diseases with a special focus on disorders that may originate in early life. An important aspect in this regard is maternal diet and nutritional status during pregnancy. Nutritional factors have long been considered to be important determinants of maternal and fetal health, and dietary information is currently being collected in a number of pregnancy cohorts in Europe and the United States. Thus far, pregnancy complications studied in MoBa are preterm birth, preeclampsia, and fetal growth; and the aim of this article is to report results of recently published studies of dietary factors in relation to these outcomes. Numerous studies are planned using MoBa data, and the aim is to add to the knowledge of the interplay between dietary factors, nonnutrients, and toxic dietary substances and epigenetic modulation on fetal development and health later in life.

    In the neutron science project at JAERI, we plan to inject a pulsed proton beam of a maximum power of 5 MW from a high intense proton accelerator into a mercury target in order to produce high energy neutrons of a magnitude of ten times or more than existing facilities. The neutrons produced by the facility will be utilized for advanced field of science such as the life sciences etc. An urgent issue in order to accomplish this project is the establishment of mercury target technology. With this in mind, a mercury experimental loop with the capacity to circulate mercury up to 15 L/min was constructed to perform thermal hydraulic tests, component tests and erosion characteristic tests. A measurement of the wall friction factor was carried out as a first step of the mercury flow tests, while testing the characteristic of components installed in the mercury loop. This report presents an outline of the mercury loop and experimental results of the wall friction factor measurement. From the wall friction factor measurement, it was made clear that the wettability of the mercury was improved with an increase of the loop operation time and at the same time the wall friction factors were increased. The measured wall friction factors were much lower than the values calculated by the Blasius equation at the beginning of the loop operation because of wall slip caused by a non-wetted condition. They agreed well with the values calculated by the Blasius equation within a deviation of 10% when the sum of the operation time increased more than 11 hours. This report also introduces technical problems with a mercury circulation and future tests plan indispensable for the development of the mercury target. (author)

    To elucidate the incidence of and risk factors for severe hypertensive disorders (HD) and related maternal complications in uncomplicated twin pregnancies that reached 36 weeks' gestation. We conducted a prospective cohort study of twin pregnancies delivered after 36 weeks' gestation. Cases of twin-twin transfusion syndrome, twin anemia-polycythemia sequence, malformed fetuses, monoamniotic twins, selective reduction, fetal therapy and HD or fetal death before 35 weeks' gestation were excluded. The study's primary outcome was the incidence of severe maternal complications, including severe HD, eclampsia, placental abruption, HELLP (hemolysis, elevated liver enzyme and low platelet) syndrome, pulmonary edema and cerebrovascular disease. Perinatal factors associated with the primary outcome were identified using a multivariate logistic regression model. In 330 enrolled women, the number of cases with the primary outcome was 28 (8.5%; 95% confidence interval 5.9-12.0), including 25 cases of severe HD and each one case of placental abruption, HELLP syndrome and eclampsia. The rate of severe maternal complications significantly increased with gestational age, demonstrating 1.2% at 36 weeks, 3.9% at 37 weeks and 6.4% at 38 weeks. Only gestational proteinuria was identified as the independent risk factor for severe maternal complications (adjusted odds ratio 17.1 [95% confidence interval 6.71-45.4]). Severe maternal HD and related complications increased from late preterm to early term; particularly, patients with gestational proteinuria were at high risk. © 2018 Japan Society of Obstetrics and Gynecology.

    Urethral stricture disease is a challenging condition to treat and several approaches including direct visual internal urethrotomy (DVIU) and anastomotic or augmentation urethroplasties based on the use of flaps and graft have been reported. The aim of this study is to determine risk factors for stricture recurrence and complications in patients having buccal mucosal graft (BMG) urethroplasty for anterior urethral stricture under a single surgeon in a third referral centre in UK. We conducted a retrospective review of a prospectively gathered database of 128 patients having various forms of BMG urethroplasty between 2001 and 2015. Success and failure in terms of stricture recurrence, patient demographics, stricture aetiology and anatomy, and the adverse outcomes of: post-micturition dribbling (PMD), erectile dysfunction (ED) >12 months and complications were recorded in order to determine risk factors for recurrent stricture and complications. The mean age of all patients was 42.8 years (range, 16-74 years). Average follow-up was 45 months (range, 3-159 months). The total re-stricture rate was 19% (24 men). PMD was reported in 16% (n=20) and ED in 12.5% (n=16). All ED was none organic and responded to oral PDE5 inhibitor treatment. Post-operative complications were reported in 16 patients (12.5%). The most frequent complications recorded were urinary fistula (n=4; 3.1%), graft contracture (n=4; 3.1%) and graft failure (n=4; 3.1%), all reported after penile urethroplasty. Univariate analysis indicated that age at surgery, stricture length, site and aetiology were all significant risk factors for stricture recurrence. On multivariate analysis penile site was the only significant independent variable for restricture. BMG urethroplasty represents a reliable therapeutic option for patient with urethral strictures with a success rate of 81% at 45 months of follow-up. Complications are more common in complex stricture of the penile urethra. On multivariate analysis penile

    Chlamydia trachomatis (CT), the most common bacterial sexually transmitted infection (STI) among young women, can result in serious sequelae. Although the course of infection is often asymptomatic, CT may cause pelvic inflammatory disease (PID), leading to severe complications, such as prolonged time to pregnancy, ectopic pregnancy, and tubal factor subfertility. The risk of and risk factors for complications following CT-infection have not been assessed in a long-term prospective cohort study, the preferred design to define infections and complications adequately. In the Netherlands Chlamydia Cohort Study (NECCST), a cohort of women of reproductive age with and without a history of CT-infection is followed over a minimum of ten years to investigate (CT-related) reproductive tract complications. This study is a follow-up of the Chlamydia Screening Implementation (CSI) study, executed between 2008 and 2011 in the Netherlands. For NECCST, female CSI participants who consented to be approached for follow-up studies (n = 14,685) are invited, and prospectively followed until 2022. Four data collection moments are foreseen every two consecutive years. Questionnaire data and blood samples for CT-Immunoglobulin G (IgG) measurement are obtained as well as host DNA to determine specific genetic biomarkers related to susceptibility and severity of infection. CT-history will be based on CSI test outcomes, self-reported infections and CT-IgG presence. Information on (time to) pregnancies and the potential long-term complications (i.e. PID, ectopic pregnancy and (tubal factor) subfertility), will be acquired by questionnaires. Reported subfertility will be verified in medical registers. Occurrence of these late complications and prolonged time to pregnancy, as a proxy for reduced fertility due to a previous CT-infection, or other risk factors, will be investigated using longitudinal statistical procedures. In the proposed study, the occurrence of late complications following

    Rectal injury is one of the major side effects after radiation therapy for carcinoma of the uterine cervix. According to our previous reports, the cases of rectal complication were mainly related to the measured rectal dose in half of patients, and the other causes were related to the following factors; such as diabetes mellitus, hemorrhagic tendency, syphilis and so on. Concerning to rectal complication, these factors were investigated by means of the discriminant analysis, one of the multivariate analyses, in this paper. Twenty-eight factors as to radiation dose, laboratory tests and physical condition of patients were analyzed. From August 1978 through January 1980, 52 cases of previously untreated carcinoma of the uterine cervix were treated using RALS, remotely controlled high dose rate intracavitary radiotherapy, at our department. The data from 49 out of 52 cases were available for the discriminant analysis. By m eans of this analysis, it was found that these factors, such as the dose of whole pelvic irradiation, Point A dose of RALS, measured rectal dose by RALS, WGC-Z and TPHA were important factors for occurence of rectal complication. According to the discriminant score, 46 out of 49 cases (94 %) could be correctly discriminated. There were two cases of false positive and one false negative. Form February 1980 through July 1980, 27 cases of previously untreated carcinoma of the uterine cervix were treated at our department. The obtained discriminant function was applied to these 27 cases, and 24 out of 27 cases (89 %) were correctly predicted. There were two cases of false positive, and one of false negative. Discriminant analysis is useful for the prediction of rectal complication after radiation therapy for carcinoma of the uterine cervix. (J.P.N.)

  6. Fisetin lowers methylglyoxal dependent protein glycation and limits the complications of diabetes.

    Directory of Open Access Journals (Sweden)

    Pamela Maher

    Full Text Available The elevated glycation of macromolecules by the reactive dicarbonyl and α-oxoaldehyde methylglyoxal (MG has been associated with diabetes and its complications. We have identified a rare flavone, fisetin, which increases the level and activity of glyoxalase 1, the enzyme required for the removal of MG, as well as the synthesis of its essential co-factor, glutathione. It is shown that fisetin reduces two major complications of diabetes in Akita mice, a model of type 1 diabetes. Although fisetin had no effect on the elevation of blood sugar, it reduced kidney hypertrophy and albuminuria and maintained normal levels of locomotion in the open field test. This correlated with a reduction in proteins glycated by MG in the blood, kidney and brain of fisetin-treated animals along with an increase in glyoxalase 1 enzyme activity and an elevation in the expression of the rate-limiting enzyme for the synthesis of glutathione, a co-factor for glyoxalase 1. The expression of the receptor for advanced glycation end products (RAGE, serum amyloid A and serum C-reactive protein, markers of protein oxidation, glycation and inflammation, were also increased in diabetic Akita mice and reduced by fisetin. It is concluded that fisetin lowers the elevation of MG-protein glycation that is associated with diabetes and ameliorates multiple complications of the disease. Therefore, fisetin or a synthetic derivative may have potential therapeutic use for the treatment of diabetic complications.

    In this study, we aimed to evaluate some laboratory and clinical factors in the prediction of latency period for pregnant patients complicated with preterm premature rupture of the membranes. Sixty-five pregnant patients between 24 and 34 weeks of gestation, who were admitted to University of Çukurova School of Medicine Hospital with the diagnosis of preterm premature rupture of the membranes (PPROM) between January 01, 2013 and December 31, 2013, were included in this study. Serum CRP, procalcitonin, sedimentation rate, leukocyte count and cervical length (measured with transvaginal ultrasound) of patients were analyzed for the correlation with the latency period. None of the parameters were found to be correlated with the latency period. However, patients with cervical length of premature rupture of the membranes is thought to be either an infection-based disease or a disease increasing the risk of infectious complications, major infection markers are not found to be helpful criteria for the prediction of latency period. Patients with a cervical length of <25 mm can be expected to deliver earlier and, therefore, can be referred to a tertiary center earlier.

    Purpose: The fundament hypothesis of conformal radiation therapy is that tumor control can be increased by using conformal treatment techniques that allow a higher tumor dose while maintaining an acceptable level of complications. To test this hypothesis, it is necessary first to estimate the incidence of morbidity for both standard and conformal fields. In this study, we examine factors that influence the incidence of late Grade 3 and 4 morbidity in patients treated with conformal and standard radiation treatment for prostate cancer. Methods and Materials: Six hundred sixteen consecutive patients treated with conformal or standard techniques between 1986 and 1994 to doses greater than 65 Gy and with more than 3 months follow-up were analyzed. No patients treated with prostatectomies were included in the analysis. The conformal technique includes special immobilization by a cast, careful identification of the target volume in three dimensions, localization of the inferior border of the prostate using a retrograde urethrogram, and individually shaped portals that conform to the Planning Target Volume (PTV). Multivariate analysis using a proportional hazards model compares differences in the incidence of Radiation Therapy Oncology Group/European Organization for Research and Center Treatment (RTOG/EORTC) Grade 3 and 4 late gastrointestinal (GI) and genitourinary (GU) morbidity by technique, T-stage, grade, age, hormonal treatment, irradiated volume, dose, and comorbid conditions. Grade 3 rectal bleeding was defined as requiring three or more cautery procedures. Results: The overall actuarial incidence of genitourinary (GU) toxicities at 5 years was 3.4%, with the crude incidence being six cases in 616 patients satisfying the selection criteria; for gastrointestinal (GI) toxicities, the overall actuarial incidence was 2.7%, with the crude incidence being 13 cases out of 616 patients. The average time to complication for our patients was 12.8 months for GI toxicity and

    Increased life expectancy have an effect on the rising percentage of elderly population in Indonesia and health problem associated with the elderly, particularly immobilization. Immobilization may cause various complications, especially when it has been overlooked without any appropriate and proper medical care in keeping with the procedures. High incidence of immobilization in elderly and the life-threatening complication call for an agreement on management of immobilization and its complication. Management of immobilization needs interdisciplinary team-work cooperation, the patients and their family. The management may be commenced through a complete geriatric review, formulating functional goals and constructing therapeutic plan. Various medical conditions and external factors that may act as risk factors of immobilization as well as drugs intake that may exaggerate the immobilization should be evaluated and optimally managed. Any complication due to immobilization and other concomitant disease/condition should be recognized and managed comprehensively in order to reduce morbidity and mortality. Management of immobilization and its complications include pharmacological and non-pharmacological treatment, i.e. various mobility exercises, utilization of ambulatory device and supporting appliance for assisting patients in stand-up position, as well as the management of urinary voiding and defecation.

    We aimed to validate the Inventory of Complicated Grief (ICG)-Korean version among 1,138 Korean adolescents, representing a response rate of 57% of 1,997 students. Participants completed a set of questionnaires including demographic variables (age, sex, years of education, experience of grief), the ICG, the Children's Depression Inventory (CDI) and the Lifetime Incidence of Traumatic Events-Child (LITE-C). Exploratory factor analysis was performed to determine whether the ICG items indicated complicated grief in Korean adolescents. The internal consistency of the ICG-Korean version was Cronbach's α=0.87. The test-retest reliability for a randomly selected sample of 314 participants in 2 weeks was r=0.75 (PKaiser-Meyer-Olkin Measure of Sampling Adequacy=0.911; Bartlett's Test of Sphericity, χ(2)=13,144.7, P<0.001). After omission of 3 items, the value of Cronbach's α increased from 0.87 for the 19-item ICG-Korean version to 0.93 for the 16-item ICG-Korean version. These results suggest that the ICG is a useful tool in assessing for complicated grief in Korean adolescents. However, the 16-item version of the ICG appeared to be more valid compared to the 19-item version of the ICG. We suggest that the 16-item version of the ICG be used to screen for complicated grief in Korean adolescents.

    Purpose: This study aimed to assess the predictive values of geometrical sparing factors for the rectum and bladder in high-dose-rate intracavitary brachytherapy (HDRICB) for Grade 2 and higher late sequelae in patients with cervical cancer. Methods: A total of 392 patients were enrolled in this study. They were treated with external beam radiotherapy to the pelvis, after which HDRICB was performed using Ir-192 remote after-loading at 1-week intervals for three or four sessions. The geometrical sparing factor (GSF) was defined as the average of the ratios between the reference doses and the Point A dose. Results: A total of 46 patients (11.7%) had Grade 2 or higher late rectal complications (36 Grade 2, 9 Grade 3, and 1 Grade 4). In all, 32 patients (8.2%) had Grade 2 or higher late bladder complications (14 Grade 2, 16 Grade 3, and 2 Grade 4). Multivariate analysis demonstrated a high risk of rectal sequelae in patients who developed bladder complications (p = 0.0004, hazard ratio 3.54) and had a rectal GSF greater than 0.7 (p = 0.01, hazard ratio 1.99). The high risk factors for bladder complications were development of rectal complications (p = 0.0004, hazard ratio 3.74), concurrent chemotherapy (p = 0.0001, relative risk 3.94), and a bladder GSF greater than 0.9 (p = 0.01, hazard ratio, 2.53). Conclusion: This study demonstrates the predictive value of GSFs in HDRICB for cervical cancer. Patients with rectal GSFs greater than 0.7 or bladder GSFs greater than 0.9 are at risk for Grade 2 and higher late sequelae.

    The purpose of this study was to assess the mortality and risk factors of complications after pneumonectomy for lung cancer. Between 1996 and 2001, we reviewed and analysed the demographic, clinical, functional, and surgical variables of 168 patients to identify risk factors of postoperative complications by univariate and multivariate analyses with Medlog software system. The mean age was 60+/-10 years, overall mortality and morbidity rates were 4.17% and 41.6%, respectively. All frequencies of respiratory complications were 1.2% for acute respiratory failure, 10.1% for pneumonia, 2.4% for acute pulmonary oedema, 4.17% for bronchopleural fistula, 2.4% for thoracic empyema and 18.5% for left recurrent nerve injuries. Postoperative arrhythmias developed in 46% of our patients. The risk factors for cardiopulmonary morbidity and mortality with univariate analysis were advanced age (P<0.01), preoperative poor performance status (P<0.015), and chronic artery disease (P<0.008). Factors adversely affecting morbidity with multivariate analysis included age (P=0.0001), associated cardiovascular disease (P=0.001), and altered forced expiratory volume in 1 s (P=0.0005). Complications after pneumonectomy are associated with high mortality. Careful attention must be paid to patients with advanced age and heart disease. Chest physiotherapy is paramount to have uneventful outcomes.

    1999-01-01

    It has been a critical issue to predict the safety critical software reliability in nuclear engineering area. For many years, many researches have focused on the quantification of software reliability and there have been many models developed to quantify software reliability. Most software reliability models estimate the reliability with the failure data collected during the test assuming that the test environments well represent the operation profile. User's interest is however on the operational reliability rather than on the test reliability. The experiences show that the operational reliability is higher than the test reliability. With the assumption that the difference in reliability results from the change of environment, from testing to operation, testing environment factors comprising the aging factor and the coverage factor are developed in this paper and used to predict the ultimate operational reliability with the failure data in testing phase. It is by incorporating test environments applied beyond the operational profile into testing environment factors. The application results show that the proposed method can estimate the operational reliability accurately. (Author). 14 refs., 1 tab., 1 fig

    Full Text Available Introduction. Infectious and inflammatory complications , such as pneumonia and burn sepsis, often develop in patients with extensive burns, thus causing high mortality. The aim of the work was to determine the risk factors for the development of infectious and inflammatory complications in patients with burns. Materials and methods. The study involved 140 burned patients divided into two groups: Group 1 – 78 patients who underwent necrectomy within 3-7 days after the burn, Group 2 (control – 62 patients with necrectomy performed in later period. Results of the research. In the 1st group pneumonia was diagnosed in 11 (14.10 ± 3.94% patients, sepsis – in 13 (16.67 ± 4.22%. In the control group pneumonia was diagnosed in 20 (32.26 ± 5.94% patients, sepsis – in 23 (37.10 ± 6.13% (p < 0.05. In the burned patients of the main group the development of infectious and inflammatory complications was observed mainly in patients over 45 years of age (43%, that is 2.9 times more often than in the patients of younger age (p < 0.05. In patients with the severity index of burn damage exceeding 90 units complications were diagnosed in 32.14 ± 6.24% of cases, which is 7 times more than in the other subgroup (p < 0.05. In the control group patients with the severity index of destruction exceeding 90 units had complications in 56.41 ± 7.94% of cases, which is 2.6 times more than in patients with less severity index (p = 0.004. If the total area of the skin burns was over 40%, the number of sepsis and pneumonia complications significantly increased in both groups, and was 1.7 times greater than in patients with a smaller area of the burn. If the area of deep skin burns was over 25%, the number of cases of pneumonia and sepsis in patients of the main group increased in 2.4 times, and in the control group it was in 1.6 times higher. Among patients with area of deep burns exceeding 40% the incidence of sepsis and pneumonia was 78% (p = 0.03 in the main

    This study evaluated early bowel complications in cervix cancer patients, following external radiotherapy (ERT) and high dose rate intracavitary radiation (HDR ICR). Factors affecting the risk of developing early bowel complications and its incidence are analyzed and discussed. The study is the retrospective review of 66 patients who received radiotherapy at Chungbuk National University Hospital from April 1994 to December 1998. The patients underwent 41.4 or 50.4 Gy ERT according to FIGO stage and tumor size, then A point dose was boosted to 71.4 or 74.4 Gy using a remotely controlled after loading Buchler HDR ICR. The EORTC/RTOG morbidity criteria were used to grade early bowel complications, which are valid from day 1, the commencement of therapy, through day 90. The actuarial incidence, severity of complications were investigated and clinical pretreatment factors relevant to complications were found through univariate (Wilcoxon) and multivariate (Cox proportional hazard model) analysis. Of the 66 patients, 30 patients (46%) developed early bowel complications; 25 patients (38%) with grade 1 or 2, 4 patients (6%) with grade 3 and 1 patient (2%) with grade 4. The complications usually began to occur 3 weeks after the commencement of radiotherapy. The actuarial incidence of early bowel complications was 41% at 10 weeks. The early bowel complications were associated significantly with an old age and a history of previous abdomino-pelvic surgery. All three patients who had a protracted overall treatment time (about 2 weeks) due to severe bowel complication, suffered from pelvic recurrences. Forty six percent of patients experienced early bowel complications, most of which were grade 1 or 2 and relieved spontaneously or by medication. The patients with an old age or a previous surgery have a high probability of early complications and they may be less compliant with planned radiotherapy. So more careful precaution is necessary for these patients

    In living donor liver transplantation (LDLT), the recipient bile duct is thin and short. Bile duct complications often occur in LDLT, with persistent long-term adverse effects. Recently, we began to perform microsurgical reconstruction of the bile duct. The purpose of this study was to investigate the relationship between bile duct reconstruction methods and complications in LDLT. From 1991 to 2014, we performed 161 LDLTs (pediatric:adult = 90:71; left lobe:right lobe = 95:66). In this study, we retrospectively investigated the initial bile duct complications in LDLT and performed univariate and multivariate analyses to identify the independent risk factors for complications. The most frequent complication was biliary stricture (9.9%), followed by biliary leakage (6.8%). On univariate and multiple logistic regression analysis, the independent risk factors for biliary stricture were bile leakage (P = .0103) and recurrent cholangitis (P = .0077). However, there were no risk factors for biliary leakage on univariate analysis in our study. The reconstruction methods (hepaticojejunostomy or duct-to-duct anastomosis) and reconstruction technique (with or without microsurgery) were not risk factors for biliary stricture and leakage. In this study, the most frequent complication of LDLT was biliary stricture. The independent risk factors for biliary stricture were biliary leakage and recurrent cholangitis. Duct-to-duct anastomosis and microsurgical reconstruction of the bile duct were not risk factors for biliary stricture and leakage. Copyright © 2016 Elsevier Inc. All rights reserved.

    To assess the scope and determining risk factors related to the development of pneumothorax throughout CT-guided biopsy of pulmonary lesions in coaxial and non-coaxial techniques and the outcome of its management. The study included CT-guided percutaneous lung biopsies in 650 consecutive patients (407 males, 243 females; mean age 54.6 years, SD 5.2) from November 2008 to June 2013 in a retrospective design. Patients were classified according to lung biopsy technique into coaxial group (318 lesions) and non-coaxial group (332 lesions). Exclusion criteria for biopsy were lesions pneumothorax were classified into: (a) Technical risk factors, (b) patient-related risk factors, and (c) lesion-associated risk factors. Radiological assessments were performed by two radiologists in consensus. Mann-Whitney U test and Fisher's exact tests were used for statistical analysis. p values pneumothorax complicating CT-guided lung biopsy was less in the non-coaxial group (23.2 %, 77 out of 332) than the coaxial group (27 %, 86 out of 318). However, the difference in incidence between both groups was statistically insignificant (p = 0.14). Significant risk factors for the development of pneumothorax in both groups were emphysema (p pneumothorax in the non-coaxial group was significantly correlated to the number of specimens obtained (p = 0.006). This factor was statistically insignificant in the coaxial group (p = 0.45). The biopsy yield was more diagnostic and conclusive in the coaxial group in comparison to the non-coaxial group (p = 0.008). Simultaneous incidence of pneumothorax and pulmonary hemorrhage was 27.3 % (21/77) in non-coaxial group and in 30.2 % (26/86) in coaxial group. Conservative management was sufficient for treatment of 91 out of 101 patients of pneumothorax in both groups (90.1 %). Manual evacuation of pneumothorax was efficient in 44/51 patients (86.3 %) in both groups and intercostal chest tube was applied after failure of manual evacuation (7

    Objective This study aimed to determine the incidence of major complications following both primary and revision transsphenoidal pituitary surgery. Major complications included endocrinopathic, skull base, orbital, hemorrhagic and thromboembolic complications, respiratory failure, and death. Secondarily, this study aimed to examine factors associated with the occurrence of complications. Study Design Retrospective cohort analysis of California and Florida all-payer databases from 2005-2008. Methods The major complication rate following both primary and revision transsphenoidal pituitary surgery was calculated. Bivariate analyses were performed to investigate the relationship of patient characteristics with complication occurrence, and a multivariate model was constructed to determine risk factors associated with these complications. Results 5,277 primary cases and 192 revision cases met inclusion criteria. There was a non-significant absolute difference of 3.09% (95% CI −11.00 to 16.14) between the rate of complications following primary (n=443; 8.39%) and revision (n=22; 11.46%) surgeries. Multivariate analyses showed that patients with Medicare (OR=1.74; 95% CI 1.17 to 2.61), Medicaid (OR=2.13; 95% CI 1.59 to 2.86), or a malignant neoplasm (OR=3.10; 95% CI 1.62 to 5.93) were more likely to have complications. Conclusions The rate of major complications following transsphenoidal pituitary surgery is lower than earlier retrospective reports. The overall complication rate following revision surgery was not significantly different from primary surgery. Insurance status and a diagnosis of a malignant neoplasm were associated with a higher rate of complications. PMID:25263939

    To determine the frecuency of complications during the management of bladder trauma and its associated factors in a third level reference Hospital. A cross-sectional study of adult patients admitted in a reference Hospital from January 2006 to June 2011 with the diagnosis of bladder trauma. We identified demographic variables, type of trauma (blunt, penetrating), diagnostic method, associated traumatisms, management of bladder traumatism, frequency of complications and mortality. Univariate analysis was performed with frequency tables, measures of central tendency and dispersion. Similarly, bivariate analysis was performed to explore the association between variables. We used chi-square test for categorical variables and Student's t test to compare quantitative variables. We reviewed 40 medical records, which met the eligibility criteria. The median age was 27 years (range 16-;67) and 85% (34 patients) were male. Twenty-nine patients (72.5%) had penetrating injuries, being mainly firearm projectile (96.55%) and 11 patients (27.5%) blunt injuries. Most patients had intraoperative diagnosis (67.5%), while 25%, 5% and 2% were diagnosed by CT-cystography, cystoscopy and voiding cystography respectively. 70% (28 patients) had intraperitoneal bladder injuries. Of the forty patients enrolled, thirty six (90%) underwent surgery, while only four (10%) received conservative management. A total of ten patients (25%) had some type of complication. The most frequent was persistent hematuria (40%) followed by surgical site infection (30%), orchitis (20%), urinary tract infection (10%), urine leakage through the operative site, or to the peritoneal cavity (10%). No mortality was detected. On the bivariate logistic regression model type of trauma, number of injuries, performance of cystostomy, use of perivesical drainage tube, chest trauma and small bowel trauma, no association was found with the presence of complications. The frequency of complications was 25%. The presence of

    Full Text Available Abstract Background Awareness of the danger signs of obstetric complications is the essential first step in accepting appropriate and timely referral to obstetric and newborn care. The objectives of this study were to assess women's awareness of danger signs of obstetric complications and to identify associated factors in a rural district in Tanzania. Methods A total of 1118 women who had been pregnant in the past two years were interviewed. A list of medically recognized potentially life threatening obstetric signs was obtained from the responses given. Chi- square test was used to determine associations between categorical variables and multivariate logistic regression analysis was used to identify factors associated with awareness of obstetric danger signs. Results More than 98% of the women attended antenatal care at least once. Half of the women knew at least one obstetric danger sign. The percentage of women who knew at least one danger sign during pregnancy was 26%, during delivery 23% and after delivery 40%. Few women knew three or more danger signs. According to multivariate logistic regression analysis having secondary education or more increased the likelihood of awareness of obstetric danger signs six-fold (OR = 5.8; 95% CI: 1.8–19 in comparison with no education at all. The likelihood to have more awareness increased significantly by increasing age of the mother, number of deliveries, number of antenatal visits, whether the delivery took place at a health institution and whether the mother was informed of having a risks/complications during antenatal care. Conclusion Women had low awareness of danger signs of obstetric complications. We recommend the following in order to increase awareness of danger signs of obstetrical complications: to improve quality of counseling and involving other family members in antenatal and postnatal care, to use radio messages and educational sessions targeting the whole community and to intensify

    Neurological complications after lung transplantation are common. The full spectrum of neurological complications and their impact on clinical outcomes has not been extensively studied. We investigated the neurological incidence of complications, categorized according to whether they affected the central, peripheral or autonomic nervous systems, in a series of 109 patients undergoing lung transplantation at our center between January 1 2013 and December 31 2014. Fifty-one patients (46.8%) presented at least one neurological complication. Critical illness polyneuropathy-myopathy (31 cases) and phrenic nerve injury (26 cases) were the two most prevalent complications. These two neuromuscular complications lengthened hospital stays by a median period of 35.5 and 32.5 days respectively. However, neurological complications did not affect patients' survival. The real incidence of neurological complications among lung transplant recipients is probably underestimated. They usually appear in the first two months after surgery. Despite not affecting mortality, they do affect the mean length of hospital stay, and especially the time spent in the Intensive Care Unit. We found no risk factor for neurological complications except for long operating times, ischemic time and need for transfusion. It is necessary to develop programs for the prevention and early recognition of these complications, and the prevention of their precipitant and risk factors.

    To determine hip arthroscopy surgical volume trends from 2006 to 2013 using the National Surgical Quality Improvement Program (NSQIP) database, the incidence of 30-day complications of hip arthroscopy, and patient and surgical risk factors for complications. Patients who underwent hip arthroscopy from 2006 to 2013 were identified in the NSQIP database for the over 400 NSQIP participating hospitals from the United States using Current Procedural Terminology and International Classification of Diseases, Ninth Revision codes. Trends in number of hip arthroscopy procedures per year were analyzed. Complications in the 30-day period after hip arthroscopy were identified. Univariate and multivariate regression analyses were performed to identify risk factors for complications. We identified 1,338 patients who underwent hip arthroscopy, with a mean age of 39.5 ± 13.0 years. Female patients comprised 59.6%. Hip arthroscopy procedures became 25 times more common in 2013 than 2006 (P arthroscopy. Hip arthroscopy is an increasingly common procedure, with a 25-fold increase from 2006 to 2013. There is a low incidence of 30-day postoperative complications (1.3%), most commonly bleeding requiring a transfusion, return to the operating room, and superficial infection. Regional/monitored anesthesia care and steroid use were independent risk factors for minor complications. Level III, retrospective comparative study.

    The aim of this study was to evaluate the incidence, radiographic appearance, time of onset, outcome and risk factors of non-infectious and infectious pulmonary complications following liver transplantation. Chest X-ray features of 300 consecutive patients who had undergone 333 liver transplants over an 11-year period were analysed: the type of pulmonary complication, the infecting pathogens and the mean time of their occurrence are described. The main risk factors for lung infections were quantified through univariate and multivariate statistical analysis. Non-infectious pulmonary abnormalities (atelectasis and/or pleural effusion: 86.7%) and pulmonary oedema (44.7%) appeared during the first postoperative week. Infectious pneumonia was observed in 13.7%, with a mortality of 36.6%. Bacterial and viral pneumonia made up the bulk of infections (63.4 and 29.3%, respectively) followed by fungal infiltrates (24.4%). A fairly good correlation between radiological chest X-ray pattern, time of onset and the cultured microorganisms has been observed in all cases. In multivariate analysis, persistent non-infectious abnormalities and pulmonary oedema were identified as the major independent predictors of posttransplant pneumonia, followed by prolonged assisted mechanical ventilation and traditional caval anastomosis. A ''pneumonia-risk score'' was calculated: low-risk score ( 3.30) population. The ''pneumonia-risk score'' identifies a specific group of patients in whom closer radiographic monitoring is recommended. In addition, a highly significant correlation (p<0.001) was observed between pneumonia-risk score and the expected survival, thus confirming pulmonary infections as a major cause of death in OLT recipients.

    Full Text Available Modern clinical medicine and surgery problems are associated with infections complications after medical care. In recent years, surgery has made substantial progress related to the new organizational approaches and medical technology specialized medical care to the wounded and injured. However, these gains are offset by a high rate of infectious complications that require finding effective measures emerging infectious complications timely diagnosis and their prevention. Clinical manifestations are often nosocomial in patients with severe injuries and are largely determined by the influence of clinical and pathogenetic risk factors. Such infectious complications require a comprehensive assessment, including microbiological testing. The main causative agents of infectious complications in surgical hospitals are S. aureus, K. pneumoniae, P. aeruginosa, Acinetobacter spp., which can cause bloodstream infections, soft tissue, respiratory and urinary tract infections, especially in debilitated and immunocompromised patients and patients in intensive care units. These micro organisms are dangerous to patients and medical staff, as they can survive for a long time in the hospital environment, as well as to spread from patient to patient in violation of isolation restrictive measures and requirements for hygiene of medical workers hands. Clinical patterns of infection associated with medical care for severe injuries are to the possibility of serial and parallel development, both in different and in the same time frame of local, visceral and generalized infection with prevalence of combined forms of patients surgical hospital with a high risk of nosocomial infection against the background of factors, diagnostic and treatment process and hospital environment, introduction of the agent. Early etiological diagnosis allows timely assign empirical causal treatment and arrange for infection control to prevent the spread of microorganisms in the hospital. The

    Transplantation of the pancreas is an increasingly common therapeutic option for preventing or delaying complications of type I diabetes mellitus. The authors studied the relative roles of various radiologic examinations in diagnosing vascular complications in these grafts including arterial and venous thrombosis, stenosis, and anastomotic leak (the most common vascular factors that necessitate pancreatectomy of the transplant), as defined with pathologic or arteriographic data. The results of 78 scintigraphic flow studies, 40 abdominal and pelvic computed tomographic (CT) scans, 27 sonograms, and eight color Doppler studies were evaluated in 52 patients who received a total of 27 cadaveric and 26 living-donor grafts over a 12-year period. These results were correlated with the data from 45 gross and microscopic pathologic studies and 37 arteriograms to determine their relative value in enabling detection of graft thrombosis and other vascular complications. Scintigraphy, CT, sonography, and color Doppler were all sensitive in detection of generalized graft abnormalities but lacked specificity in defining the underlying etiologic factors

    To report the use of intravitreal (IVT) injections of anti-vascular endothelial growth factor agents (anti-VEGF) and its complications. The authors performed a retrospective review of consecutive patients treated with IVT injection of anti-VEGF between May 2006 and December 2010 at Chiang Mai University Hospital. Demographic data and complications were registered. The present study included 1,006 eyes of 878 patients. Mean age was 60 years (range 1 month to 91 years). Mean follow-up time was 12 months (range 1 month to 54 months). Total injections were 2,077 given as 47, 210, 399, 575, and 846 injection per year between 2006 and 2010, respectively. Anti-VEGF agents were bevacizumab (1,878; 90.42%), ranibizumab (190; 9.15%), and pegaptanib (9; 0.43%). Indications for injection based on primary diagnosis were neovascular macular degeneration (38.5%), diabetic retinopathy (38%), and retinal vein occlusion (15.9%). The incidence of endophthalmitis was 0.048% (1/2,077) for all injections and 0.053% (1/1878)for bevacizumab. The use of IVT injections of anti-VEGF is increasing, especially the use of bevacizumab. Incidence of ocular and systemic complications after IVT injection of anti- VEGF was low with no significant difference among the three anti-VEGFs agents.

    The aim of this study is to evaluate the complications of humeral lengthening and their associated factors. Fifty-four achondroplastic patients were treated by bilateral humeral lengthening. Our original shoulder sling was sufficient to prevent shoulder dislocation. Pre-existing radial head dislocation was observed in 18 patients. Lengthening was accomplished in all cases without a decrease in the elbow function. Seven humeri fractured after the fixator removal. The risk factors for postoperative fracture were a waiting period of less than 5 days, a healing index less than 25, and the concave shape of the callus. There was no radial nerve palsy.

    Full Text Available Introduction: Insertion of a double-J (JJ stent is a common procedure often carried out in the retrograde route by the urologists and the antegrade route by the radiologists. Reported complications include stent migration, encrustation, and fracture. Extra-anatomic placement of an antegrade JJ stent is a rare but infrequently recognized complication. Materials and Methods: We performed a retrospective audit of 165 antegrade JJ stent insertions performed over three consecutive years by a single interventional radiologist. All renal units were hydronephrotic at the time of nephrostomy. All procedures were performed under local anaesthetic with antibiotic prophylaxis. Results: Antegrade stent insertion was carried out simultaneously at the time of nephrostomy in 55 of the 165 cases (33%. The remainder were inserted at a mean of 2 weeks following decompression. In five (3% patients, who had delayed antegrade stenting following nephrostomy, the procedure was complicated by silent ureteric perforation and an extra-anatomic placement of the stent. These complications had delayed manifestations, which included two retroperitoneal abscesses, a pelvic urinoma, a case each of ureterorectal fistula, and ureterovaginal fistula. Risk factors for ureteric perforation include previous pelvic malignancy, pelvic surgery, pelvic radiation, and a history of ureteric manipulation. Conclusion: Antegrade ureteric JJ stenting is a procedure not without complications. Extra-anatomic placement of the antegrade stent is a hitherto the infrequently reported complication but needs a high index of suspicion to be diagnosed. Risk factors for ureteric perforation at the time of stent insertion have to be considered to prevent this potential complication.

    2010-01-01

    Objective: Thyroidectomy is a very common surgical procedure worldwide and is performed by surgeons with varied training. The outcome and complication rates are largely dependent on surgeon's skill and experience, the extent of surgery, indication of surgery and number of thyroid surgeries performed at that particular centre. The objective of this study was to determine the frequency of postoperative complications after thyroid surgery in Hyderabad, Pakistan. Study Design: It was a descriptive study and was carried out at 2 private hospitals including a teaching University Hospital over a period of 3 years from April 2005 to March 2008. Patients and Methods: All patients with goitre, who underwent any sort of thyroid surgery, were included in this study. Patients' bio-data including name, age sex, clinical status of thyroid, thyroid function tests, ultrasound, fine needle aspiration cytology and operative procedure, findings, post operative complications and histopathology reports were recorded. Data were analysed using SPSS 16.0. Results: The overall postoperative complication rate was 10.7%. Postoperative hypocalcaemia was the most frequent complication observed in 3.5% of all patients followed by recurrent laryngeal nerve (RLN) injury noted in 2.8% patients. The less common complications were bleeding, seroma formation and wound infection. Majority of these complications were associated with total thyroidectomy, male gender, and in patients with age more than 30 years. Conclusion: The commonest post thyroidectomy complication was hypocalcaemia. Male gender, old age, and extensive thyroid surgery were associated with increased complication rate. (author)

    Urinary tract infections (UTI) are the most common bacterial infections involving lower (cystitis, prostatitis) or upper (pyelonephritis, renal abscess, perinephric abscess) urinary tract. Differentiation of complicated and uncomplicated UTI is usually based on the presence of structural or functional urinary tract abnormalities, which can increase the risk of treatment failure and development of serious complications. Factors that increase the risk are foreign bodies, stones, obstruction, neurogenic bladder, kidney transplantation, immunosuppression, and pregnancy. Complicated UTI includes a spectrum of conditions that increase the risk of treatment failure, as well as of serious complications such as bacteremia and sepsis, perinephric abscess, renal impairment and emphysematous pyelonephritis. To avoid the potentially devastating outcomes, appropriate diagnostic procedures, antibiotic and surgical treatment, and appropriate follow-up are required. The incidence of complicated UTI will grow in the future due to general aging of the population, increasing incidence of diabetes, and ever growing number of immunocompromised and immunosuppressed patients. It is of key importance to recognize complicated UTI on time, and treat it wisely and aggressively to reduce duration of the disease and the risk of antibiotic resistance.

    2017-12-01

    Two marginal one-parameter item response theory models are introduced, by integrating out the latent variable or random item parameter. It is shown that both marginal response models are multivariate (probit) models with a compound symmetry covariance structure. Several common hypotheses concerning the underlying covariance structure are evaluated using (fractional) Bayes factor tests. The support for a unidimensional factor (i.e., assumption of local independence) and differential item functioning are evaluated by testing the covariance components. The posterior distribution of common covariance components is obtained in closed form by transforming latent responses with an orthogonal (Helmert) matrix. This posterior distribution is defined as a shifted-inverse-gamma, thereby introducing a default prior and a balanced prior distribution. Based on that, an MCMC algorithm is described to estimate all model parameters and to compute (fractional) Bayes factor tests. Simulation studies are used to show that the (fractional) Bayes factor tests have good properties for testing the underlying covariance structure of binary response data. The method is illustrated with two real data studies.

    To report our experience of common sheath reimplantation (CSR) for ectopic ureterocele (EU) combined with ureteral duplication, describing success rates and postoperative complications, along with risk factors for developing postoperative incontinence. When the upper tract approach is not indicated in patients with EU, a bladder-level approach, involving either CSR or total reconstruction, is the remaining option. However, concerns exist about the high morbidity of bladder-level approaches. We retrospectively examined the postoperative results of 39 patients who underwent CSR between January 2001 and December 2012. Risk factors for the development of postoperative incontinence and decreases in differential renal function (DRF) were additionally analyzed. The median age at operation was 16.5 months. After CSR, upper urinary tract dilatation decreased in 36 patients (92.3%). During a median follow-up of 75.9 months, an additional operation was required in 7 patients (17.9%). Postoperative incontinence developed in 3 patients (7.7%). Median preoperative DRF was significantly lower in the postoperative incontinence group (P = .004). DRF decreased postoperatively in 5 of 36 patients (13.9%). No preoperative factors were related to the decrease in DRF. No patient developed hypertension or proteinuria. CSR decompressed the upper urinary tract effectively in our EU patients. Postoperative incontinence does not seem to be related to operation factors, but with preoperative DRF. When the upper tract approach is not indicated, CSR is a reasonable alternative. Total reconstruction is unnecessary as the remnant upper pole kidney after CSR does not lead to complications.

    To identify litigation predictors among women with complications of transvaginal mesh. Chart review and patient survey were conducted among women who had undergone a complication-related explant of a transvaginal prolapse or incontinence sling mesh. Trained study personnel administered a 57-question survey addressing subjective complaints related to bowel, bladder, sexual dysfunction, and development of pain or recurrent prolapse. These data were analyzed with respect to the subject's reported pursuit of litigation related to the mesh complication. Categorical and continuous variables were analyzed using the χ test and the t test as indicated. Ninety-five (68%) of 139 women completed the surveys with 60% of the patients pursuing litigation at the time of the survey. Individual risk factors for pursuing litigation included development of vaginal pain after mesh placement (P = 0.01); dyspareunia after mesh placement (P = 0.01); persistence of dyspareunia, suprapubic pain, and groin pain after mesh excision (P = 0.04, P = 0.02, and P = 0.001, respectively); unsuccessful attempts at conservative management of pelvic pain using pelvic floor rehabilitation (P = 0.002). There is an association between a higher likelihood of pursuing litigation and new-onset or persistent pain symptoms attributable to transvaginal mesh.

    The aim of this study was to evaluate a possible relationship between lunar cycles and haemorrhagic complication rate in surgery. The possible relationship between moon phases and surgical outcome was tested by evaluating the haemorrhagic complication rate for 18,760 patients who underwent surgery between January 2001 and December 2008 at the National Institute for Cancer Research in Genoa. A total of 103 lunar phases were considered using Chi-square (χ 2 ) test analysis, and patients were allocated a surgery date. One hundred and sixty-seven haemorrhagic complications were observed. Three hundred and nine new moon phase days were analysed and 12 incidences of complications detected, with a 3.9% complication rate per day. In the waxing moon phase, 1184.5 d were analysed with 68 incidences of complications at a daily rate of 5.7%. In the full moon phase there was a 4.9% complication rate per day (15 incidences in 309 d), whereas in the waning moon phase, the 6% percentage rate per day resulted from 72 incidences in 1184.5 d. No statistically significant correlations were found between moon cycles and postoperative haemorrhagic complications (p = .50).

    The objective of our study was to identify the incidence and risk factors of anastomotic leaks following transhiatal esophagectomy (THE). A prospective study was conducted on 61 patients treated for carcinoma of the esophagus between 2006 and 2007. We examined the following variables: age, gender, preoperative cardiovascular function, intraoperative complications such as hypotension, arrhythmia, mediastinal manipulation period, blood loss volume, blood transfusion, duration of surgery, postoperative complications such as anastomotic leak, anastomotic stricture, requiring reoperation, respiratory complications, and total morbidity and mortality. Variables were compared between the patients with and without anastomotic leak. T-test for quantitative variables and Chi-square test for qualitative variables were used to find out any relationship. P value less than 0.05 was considered significant. Out of 61 patients, anastomotic leaks occurred in 13 (21.3%). Weight loss, forced expiratory volume (FEV1) < 2 lit, preoperative albumin, intaoperative blood loss volume, and respiratory complication were associated with the anastomotic leak in patients undergoing THE. Anastomotic leaks were the leading cause of postoperative morbidity, anastomotic stricture, and reoperation. Anastomotic leakage is a life-threatening postoperative complication. Careful attention to the factors contributing to the development of a leak can reduce the incidence of anastomotic complications postoperatively. (author)

    Type I thyroplasty has become a primary surgical choice for voice restoration in patients with glottal incompetence. This study examines factors associated with laryngeal complications after type I thyroplasty. Ten laryngoscopic variables were analyzed from preoperative, intraoperative, and postoperative videolaryngoscopies of 51 patients undergoing 58 medialization procedures. Ten patient and operative variables were examined by medical record review. Major complications were defined as wound hemorrhage, airway obstruction, or prosthesis extrusion. Minor complications were defined as vocal fold hematoma without airway obstruction or prosthesis movement. The major complication rate was 8.6%, and the minor complication rate was 29%. No delayed hemorrhage or airway obstruction occurred. Prosthesis extrusion occurred in five (8.6%) patients 1 week to 5 months after surgery. Extrusion was associated with suboptimal prosthesis placement in 80% of cases. Two patients retained excellent glottal closure despite extrusion. Vocal fold hematoma was identified in 14 (24%) cases and resolved within 1 week. Prosthesis movement occurred in three (5%) patients 1 week to 6 months after surgery and resulted in poor glottal closure. All patients with prosthesis extrusion or movement were female. Type I thyroplasty remains a safe outpatient procedure with few major complications. Prosthesis extrusion was associated with suboptimal prosthesis placement and may or may not result in poor glottal closure. Minor vocal fold hematomas were relatively frequent, resolved rapidly, and were not associated with airway obstruction. Female patients may be more prone to complications because of their small laryngeal size.

    2010-03-01

    Fractional photothermolysis represents a new modality of laser skin resurfacing that was developed to provide a successful clinical response while minimizing postoperative recovery and limiting treatment complications. To review all of the reported complications that develop as a result of fractional ablative and nonablative laser skin resurfacing. A literature review was based on a MEDLINE search (1998-2009) for English-language articles related to laser treatment complications and fractional skin resurfacing. Articles presenting the highest level of evidence and the most recent reports were preferentially selected. Complications with fractional laser skin resurfacing represent a full spectrum of severity and can be longlasting. In general, a greater likelihood of developing post-treatment complications is seen in sensitive cutaneous areas and in patients with intrinsically darker skin phototypes or predisposing medical risk factors. Although the overall rate of complications associated with fractional laser skin resurfacing is much lower than with traditional ablative techniques, recent reports suggest that serious complications can develop. An appreciation of all of the complications associated with fractional laser skin resurfacing is important, especially given that many of them can be potentially prevented. The authors have indicated no significant interest with commercial supporters.

    It is known that successful pancreas transplantation enables patients with diabetes to maintain a normal glucose level without insulin and reduces diabetes-related complications. However, we have little information about the foot-specific morbidity in patients who have undergone successful pancreas transplantation. The purpose of this study was to investigate the prevalence and predisposing factors for foot complications after successful pancreas transplantation. This retrospective study included 218 patients (91 males, 127 females) who had undergone pancreas transplantation for diabetes. The mean age was 40.7 (range, 15-76) years. Diabetes type, transplantation type, body mass index, and diabetes duration before transplantation were confirmed. After pancreas transplantation, the occurrence and duration of foot and ankle complications were assessed. Twenty-two patients (10.1%) had diabetic foot complications. Fifteen patients (6.9%) had diabetic foot ulcer and 7 patients (3.2%) had Charcot arthropathy. Three patients had both diabetic foot ulcer and Charcot arthropathy. Three insufficiency fractures (1.4%) were included. Mean time of complications after transplantation was 18.5 (range, 2-77) months. Creatinine level 1 year after surgery was higher in the complication group rather than the noncomplication group ( P = .02). Complications of the foot and ankle still occurred following pancreas transplantation in patients with diabetes. Level III, comparative study.

    Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is an emerging curative treatment option for patients with peritoneal carcinomatosis. It has a long-term survival benefit but is associated with high rates of morbidity, ranging from 12 % to 65 %, mainly due to infectious complications. We sought to evaluate the clinical relevance of routine intraoperative bacteriological sampling following CRS/HIPEC. Between November 2010 and December 2014, every patients receiving CRS/HIPEC were included. Three samples were routinely collected from standardized locations for intraperitoneal rinsing liquid bacteriological analysis (RLBA) after completion of HIPEC. The clinical and surgical features, bacteriological results, and short-term outcomes were retrospectively reviewed. The overall mortality and morbidity rates were 5 and 45 %, respectively. Among the 75 included patients, 40 % (n = 30) had at least one positive bacterial culture. Risk factors for a positive culture were colorectal resection (adjusted hazard ratio [HR] = 3.072, 95 % CI 1.843-8.004; p = 0.009) and blood loss >1000 mL (HR = 4.272, 95 % CI 1.080-18.141; p = 0.031). Among 26 (35 %) patients with abdominal infectious complications, 13 (17 %) experienced isolated complications. A positive RLBA result was independently associated with abdominal infectious complications (HR = 5.108, 95 % CI 1.220-16.336; p = 0.024) and isolated abdominal infectious complications (HR = 4.199, 95 % CI 1.064-15.961; p = 0.04). Forty percent of the RLBA samples obtained following CRS/HIPEC tested positive for bacteria. Bacterial sampling of rinsing liquid should be systematically performed. An aggressive and immediate antibiotic strategy needs to be evaluated.

    Obesity has been associated with respiratory complications, and the majority of these complications occur in the Post-Anesthesia Care Unit (PACU). The aim of this study was to evaluate the outcome and incidence of adverse respiratory events (AREs) in obese patients during their stay in the PACU METHODS: We conducted a prospective control study that included 27 obese patients matched with an equal number of patients with body mass index (BMI)<30 (non-obese control group); the 2 groups of patients were similar in respect to gender distribution, age, and type of surgery and had been admitted into the PACU after elective surgery (May 2011). The AREs were identified during PACU stay. Descriptive analysis of variables was performed, and the Mann-Whitney U test, Chi-square test, or Fisher's exact test were used for comparisons. Associations with AREs were studied using univariate and multivariate logistic regression models. There was a higher frequency of STOP-BANG ≥3 (89% vs. 11%, P<.001) among obese patients and they were less frequently scheduled to undergo high-risk surgery (7% vs. 41%, P=.005) and major surgery (4% vs. 15%, P=.008). Obese patients had more frequent AREs in the PACU (33% vs. 7%, P<.018). Multivariate analysis identified obesity and residual neuromuscular blockade as independent risk factors for the occurrence of AREs. Stay in the PACU was longer for obese patients (120min vs. 84min, P<.01). Obesity was considered an independent risk factor for AREs in the PACU. Obese patients stayed longer in the PACU, but they did not stay longer in the hospital. Copyright © 2012 Sociedade Portuguesa de Pneumologia. Published by Elsevier España. All rights reserved.

    2012-04-01

    An increasing body of evidence suggests the likelihood of a link between venous and arterial thrombosis. The two vascular complications share several risk factors, such as age, obesity, smoking, diabetes mellitus, blood hypertension, hypertriglyceridemia, and metabolic syndrome. Moreover, there are many examples of conditions accounting for both venous and arterial thrombosis, such as the antiphospholipid antibody syndrome, hyperhomocysteinemia, malignancies, infections, and the use of hormonal treatment. Finally, several recent studies have consistently shown that patients with venous thromboembolism are at a higher risk of arterial thrombotic complications than matched control individuals. We, therefore, speculate the two vascular complications are simultaneously triggered by biological stimuli responsible for activating coagulation and inflammatory pathways in both the arterial and the venous system. Future studies are needed to clarify the nature of this association, to assess its extent, and to evaluate its implications for clinical practice.

Thirty-two eyes of 32 patients with tube erosion requiring surgical revision were compared with 32 matched control eyes of 32 patients. Univariate and multivariate risk factor analyses were performed.Results: Mean age was significantly younger in the tube exposure group compared with the control group (48.2±28.1 years versus 67.3±18.0 years, respectively; P=0.003. The proportion of diabetic patients (12.5% in the tube exposure group was significantly less (P=0.041 compared with the control group (37.5%. Comparisons of the type and position of the drainage implant were not significantly different between the two groups. The average time to tube exposure was 17.2±18.0 months after implantation of the drainage device. In both univariate and multivariate analyses, younger age (P=0.005 and P=0.027 and inflammation prior to tube exposure (P≤0.001 and P=0.004 were significant risk factors. Diabetes was a significant risk factor only in the univariate analysis (P=0.027.Conclusion: Younger age and inflammation were significant risk factors for tube exposure after drainage implant surgery.

    To examine the effects of obesity on specialty-specific surgical outcomes in children. Retrospective cohort study using the National Surgical Quality Improvement Program, Pediatric, 2012-2014. Patients included those aged 2-17 years who underwent a surgical procedure in one of six specialties. Obesity was the primary patient variable of interest. Outcomes of interest were postoperative complications and operative times. Odds ratios for development of postoperative complications were calculated using stepwise multivariate regression analysis. Obesity was associated with a significantly greater risk of wound complications (OR 1.24, 95% CI 1.13-1.36), but decreased risk of non-wound complications (OR 0.68, 95% CI 0.63-0.73) and morbidity (OR 0.79, 95% CI 0.75-0.84). Obesity was not a significant factor in predicting postoperative complications in patients undergoing otolaryngology or plastic surgery procedures. Anesthesia times and operative times were significantly longer for obese patients undergoing most types of pediatric surgical procedures. Obesity confers an increased risk of wound complications in some pediatric surgical specialties and is associated with overall decreased non-wound complications and morbidity. These findings suggest that the relationship between obesity and postoperative complications is complex and may be more dependent on underlying procedure- or specialty-related factors than previously suspected.

  2. Massive pulmonary embolism: the predisposing and complicating factors, its current diagnostic approaches and critical importance of early diagnostic physical exam

    Full Text Available Massive pulmonary embolism (MPE often leads to circulation collapse, a form of shock. The process is set off by thrombus or multiple thrombi dislodgement followed by a rapid perfusion insufficiency of pulmonary arterial system. Patients experience severe hypotension with diastolic and systolic failure with an acute tricuspid regurgitation. On many occasions, release of an obstruction is unattainable and death is occurring frequently within one hour of presentation. A key reported source of MPE is its occurrence as a complication of deep vein thrombosis (DVT. While long-term immobilization and surgery are both directly associated with MPE, others such as previous DVT, malignancy, infectious lung and heart diseases, family thrombophilia, lower limb paralysis and pregnancy have to be considered as risk factors mainly due to its silent nature. Predisposing and complicating risks should be addressed by an early diagnostic physical exam. The clinician might offer a wide variety of diagnostic approaches, combining techniques into algorithms to better deal with the embolism severity. Multiple patient life-style changes and decisions to adhere to the proposed plan should be built up on patient-physician team effort. KEY WORDS: Massive pulmonary embolism, predisposing factors, current diagnostic approaches.

    Full Text Available Cranioplasty is a surgical repair of a defect or deformity of a skull with the use of autologous bone or synthetic materials.[4] It usually follows decompressive craniectomy, which is a commonly practiced neurosurgical intervention in patients with raised intracranial pressure unresponsive to other forms of treatment.[1] There are many conditions that may lead to intracranial hypertension, and the goal is to avoid brain necrosis caused by compartment pressure syndrome.[2] Consequently, the extensive use of decompressive craniectomy directly results in more cranioplasties, which sometimes present with unwanted complications.[5] Generally, the occurence of cranioplasty complications is between 16% and 34%.[3] Because of the many indications for craniectomy based on clinical data that speak in its favour, if will probably remain a relatively common neurosurgical intervention also in the future. The frequency of decompressive craniectomy and consequently of cranioplasty requires awareness of the many potential postoperative complications and understanding of its evolution. This article is a review of pathophysiological mechanisms after decompressive craniectomy and cranioplasty, of its complications and factors that potentially contribute to their occurence.

    Violence against women is a worldwide public health problem and becomes more crucial when it involves pregnant women. The primary aim of this study was to determine the prevalence of violence against pregnant women (VAPW), while the secondary aim was to identify the factors associated with violence and complications of violence during pregnancy. This was a cross-sectional study conducted in 1,200 postnatal women from March 1, 2015 through August 31, 2015 using a validated Malay Version of the WHO Women's Health and Life Experiences Questionnaire. Data on pregnancy complications were obtained from antenatal records and discharge summaries. The prevalence of any form of VAPW was 35.9%, consisting of: any psychological (29.8%); any physical (12.9%); and any sexual (9.8%) violence. VAPW was significantly associated with: (1) women's use of drugs, having had exposure to violence during childhood, having a violence-supporting attitude, having two or more children; and (2) having partners who were smokers, alcohol drinkers, or had controlling behavior. VAPW was significantly associated with anemia, urinary tract infection, premature rupture of membranes, antepartum hemorrhage, poor weight gain during pregnancy, low birth weight, and prematurity. In conclusion, the high prevalence of violence requires further research on preventive strategies for VAPW.

    The aim of this study was to investigate the risk factors for access site-related complications after transradial coronary angiography (CAG) or percutaneous coronary intervention (PCI). Transradial PCI has been shown to reduce access site-related bleeding complications compared with procedures performed through a femoral approach. Although previous studies focused on risk factors for access site-related complications after a transfemoral approach or transfemoral and transradial approaches, it is uncertain which factors affect vascular complications after transradial catheterization. We enrolled 500 consecutive patients who underwent transradial CAG or PCI. We determined the incidence and risk factors for access site-related complications such as radial artery occlusion and bleeding complications. Age, sheath size, the dose of heparin and the frequency of PCI (vs. CAG) were significantly greater in patients with than without bleeding complications. However, body mass index (BMI) was significantly lower in patients with than without bleeding complications. Sheath size was significantly higher and the frequency of statin use was significantly lower in patients with than without radial artery occlusion. Multiple logistic analysis revealed that sheath size [odds ratio (OR) 5.5; P strategy that could prevent radial artery occlusion after transradial procedures.

    Colonic diverticula in reality are herniations of the mucosa through a thickened musculature of the bowel wall where it is penetrated by the vasa recta. Their prevalence increases with western food and with age. Low-residue diet and increased intraluminal pressure are considered to be etiologic factors. Diverticular disease is characterised by inflammatory and bleeding complications. Diverticulitis may lead to peridiverticulitis and pericolitis with frank peritonitis. Uncomplicated diverticulosis warrants observation only under dietary guidance. Repeated complications indicate elective operation by one-stage-resection. Perforation, abscess and massive bleeding necessitate immediate operative treatment aimed at elimination of the involved segment.

    Atherectomy has become an increasingly utilized modality for the endovascular treatment of peripheral arterial occlusive disease. The objective of this study was to determine the incidence and risk factors for atherectomy-associated complications. A retrospective review was performed for all atherectomy procedures performed between January 2011 and December 2015 in the Southern California Vascular Outcomes Improvement Collaborative. Atherectomy was defined as laser, orbital, or excisional atherectomy. Complications were dissection, perforation, and distal embolization. Seven hundred twenty-nine atherectomy procedures were performed at 7 institutions by 27 practitioners. The mean age was 73 years with 415 (57%) males. Four hundred nineteen (57%) were diabetic, 673 (92%) hypertensive, 457 (63%) smokers, and 244 (34%) had coronary artery disease. Dissection occurred in 51 (7%) procedures, embolization in 23 (3.1%), and perforation in 12 (1.6%). The mean number of lesions treated per artery was the same at 1.6 in patients with any complication and no complication (P = 0.77). The total occluded length was 7.4 cm for complications versus 7.2 cm for no complication (P = 0.73). The total treated length was 12.9 cm for complications versus 11.3 cm for no complication (P = 0.03). The incidence of complications for Trans-Atlantic Inter-Society Consensus (TASC) C/D lesions were 13% compared to 10% for TASC A/B lesions (P = 0.05). The incidence of complications in superficial femoral/popliteal lesions was 12.9% vs. 10.4% in tibial lesions (P = 0.13). In multivariable analysis, treatment length was associated with a small increased risk of complication (odds ratio = 1.02, 95% confidence interval = 1.0-1.04). Increased treatment length is associated with an increased risk of atherectomy-associated complications. Demographic factors and comorbidities were not predictors of complications.

    To investigate the actual complication rate of hysteroscopic surgery performed by experienced endoscopic surgeons in a single medical center. A prospective descriptive study (Canadian Task Force classification III). An endoscopic gynecology unit at a tertiary care university hospital. Women from 21 to 82 (median 45.0) years, undergoing operative hysteroscopy for uterine disease. Operative hysteroscopy with glycine or saline solution used as an irrigation medium. Data of short-term complications were prospectively collected during surgery and at the 2-week follow-up visit. Six hundred procedures were investigated. The total complication rate was 3%, with 1% of uterine perforations. Two-thirds of the complications were related to cervical dilation or uterine entry, and infertility was found to be a risk factor. Hysteroscopic surgery, performed by a well-trained hysteroscopic surgeon, is a safe procedure with an overall complication rate of 3%. Most complications are related to cervical dilation or uterine entry techniques. Efforts therefore should be focused on identifying the patients at risk and finding novel techniques for cervical priming.

    Conception using assisted reproduction treatments (ART) has been associated with an increased risk of pregnancy complications. It is uncertain if this is caused by ART directly, or is an association of the underlying factors causing infertility. We assessed the relationship between assisted conception (AC) and maternal or fetal complications in a large retrospective cohort study. In a nested cohort of women receiving infertility treatment, we determined if such risk rests predominantly with certain causes of infertility. Retrospective database analysis of 50 381 women delivering a singleton pregnancy in four public hospital obstetric units in western Sydney, and a nested cohort of 508 women receiving ART at a single fertility centre, in whom the cause of infertility was known. A total of 1727 pregnancies followed AC; 48 654 were spontaneous conceptions. Adjusted for age, body mass index and smoking, AC was associated with increased risk of preterm delivery (OR 1.73, 95% CI 1.50-2.02), hypertension (OR 1.55, 95% CI 1.34-1.82) and diabetes (OR 1.51, 95% CI 1.30-1.75). In the nested cohort, ovulatory dysfunction was present in 145 women and 336 had infertility despite normal ovulatory function. Ovulatory dysfunction was associated with increased risk of diabetes (OR 2.94, 95% CI 1.72-5.02) and hypertension (OR 2.40, 95% CI 1.15-5.00) compared to women with normal ovulatory function. Assisted conception is associated with increased risk of pregnancy complications. This risk appears greatest for women whose underlying infertility involves ovulatory dysfunction. Such disorders probably predispose towards diabetes and hypertension, which is then exacerbated by pregnancy. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Patients with complications of diabetes such as retinopathy, nephropathy, and cardiovascular complications have increased hospital stay with greater economic burden. Prevention of complications should be started before the onset of type 1 diabetes mellitus (T1DM) by working on risk factors and thereafter by intervention upon confirmatory diagnosis which can prevent further damage to β-cells. The actual risk of getting microvascular complications like microalbuminuria and retinopathy progression starts at glycated hemoglobin (HbA1c) level of 7%. As per the American Diabetes Association, a new pediatric glycemic control target of HbA1c 20 years as compared to patients <10 years of age. Screening of these complications should be done regularly, and appropriate preventive strategies should be followed. Angiotensin converting enzyme inhibitors and angiotensin II receptor blocker reduce progression from microalbuminuria to macroalbuminuria and increase the regression rate to normoalbuminuria. Diabetic microvascular complications can be controlled with tight glycemic therapy, dyslipidemia management and blood pressure control along with renal function monitoring, lifestyle changes, including smoking cessation and low-protein diet. An integrated and personalized care would reduce the risk of development of microvascular complications in T1DM patients. The child with diabetes who receives limited care is more likely to develop long-term complications at an earlier age. Screening for subclinical complications and early interventions with intensive therapy is the need of the hour. PMID:25941647

    The BCR-ABL1-negative myeloproliferative neoplasms (MPN) share an increased risk of thrombotic and hemorrhagic complications. Risk factors for hemorrhage are less well defined than those for thrombosis. Because patients with CALR mutations have higher platelet counts compared to JAK2 V617F-mutated patients, bleeding rates may be increased in this group. Our aim was to retrospectively evaluate whether acquired von Willebrand disease (AvWD), thrombocytosis, mutational status, or treatment history are associated with bleeding in a cohort of MPN patients. Using an electronic database, MPN patients seen between 2005 and 2013 were retrospectively identified using ICD-9 codes and billing records. A bleeding event was defined as one that was identified in the medical record and graded based on the Common Terminology Criteria for Adverse Event (CTCAE) version 4.0. Among 351 MPN patients, 15.6 % experienced 64 bleeding event types. There was no association of bleeding with mutational status, gender, MPN subtype, aspirin use, prior thrombosis, or platelet count at presentation. There was an association between bleeding and older age at diagnosis. aVWD was identified in six patients. In this single-center retrospective study, bleeding events were identified in 15 % of patients, and associated with older age at diagnosis. aVWD was rarely tested for in this cohort.

    This study retrospectively evaluates complications after lung radiofrequency ablation (RFA). Complications were assessed for each RFA session in 420 consecutive patients with 1403 lung tumors who underwent 1000 RFA sessions with a cool-tip RFA system. A major complication was defined as a grade 3 or 4 adverse event. Risk factors affecting frequent major complications that occurred with an incidence of 1% or more were detected using multivariate analysis. Four deaths (0.4% [4/1000]) related to RFA procedures occurred. Three patients died of interstitial pneumonia. The other patient died of hemothorax. The major complication rate was 9.8% (98/1000). Frequent major complications were aseptic pleuritis (2.3% [23/1000]), pneumonia (1.8% [18/1000]), lung abscess (1.6% [16/1000]), bleeding requiring blood transfusion (1.6% [16/1000]), pneumothorax requiring pleural sclerosis (1.6% [16/1000]), followed by bronchopleural fistula (0.4% [4/1000]), brachial nerve injury (0.3% [3/1000]), tumor seeding (0.1% [1/1000]), and diaphragm injury (0.1% [1/1000]). Puncture number (p risk factors for aseptic pleuritis. Previous external beam radiotherapy (p risk factors for pneumonia, as were emphysema (p lung abscess, and serum platelet count (p risk factor for pneumothorax requiring pleural sclerosis. Lung RFA is a relatively safe procedure, but it can be fatal. Risk factors found in this study will help to stratify high-risk patients.

  16. Using partial safety factors in wind turbine design and testing

    Musial, W.D. [National Renewable Energy Lab., Golden, CO (United States)

    1997-12-31

    This paper describes the relationship between wind turbine design and testing in terms of the certification process. An overview of the current status of international certification is given along with a description of limit-state design basics. Wind turbine rotor blades are used to illustrate the principles discussed. These concepts are related to both International Electrotechnical Commission and Germanischer Lloyd design standards, and are covered using schematic representations of statistical load and material strength distributions. Wherever possible, interpretations of the partial safety factors are given with descriptions of their intended meaning. Under some circumstances, the authors` interpretations may be subjective. Next, the test-load factors are described in concept and then related to the design factors. Using technical arguments, it is shown that some of the design factors for both load and materials must be used in the test loading, but some should not be used. In addition, some test factors not used in the design may be necessary for an accurate test of the design. The results show that if the design assumptions do not clearly state the effects and uncertainties that are covered by the design`s partial safety factors, outside parties such as test labs or certification agencies could impose their own meaning on these factors.

This method has been successfully implemented on the Capsule Parachute Assembly System (CPAS) for the NASA Orion crew module for use in determining the margin of safety for each component under peak loads. Also discussed are concepts behind the joint factor and what drives the loss of material strength at joints. The joint factor is defined as a "loss in joint strength...relative to the basic material strength" that occurs when "textiles are connected to each other or to metals." During the CPAS engineering development phase, a conservative joint factor of 0.80 was assumed for each parachute component. In order to refine this factor and eliminate excess conservatism, a seam and joint testing program was implemented as part of the structural validation. This method split each of the parachute structural joints into discrete tensile tests designed to duplicate the loading of each joint. Breaking strength data collected from destructive pull testing was then used to calculate the joint factor in the form of an efficiency. Joint efficiency is the percentage of the base material strength that remains after degradation due to sewing or interaction with other components; it is used interchangeably with joint factor in this paper. Parachute materials vary in type-mainly cord, tape, webbing, and cloth -which require different test fixtures and joint sample construction methods. This paper defines guidelines for designing and testing samples based on materials and test goals. Using the test methodology and analysis approach detailed in this paper, the minimum joint factor for each parachute component can be formulated. The joint factors can then be used to calculate the design factor and margin of safety for that component, a critical part of the design verification process.

    Slipped upper femoral epiphysis (SUFE) is a multifactorial condition usually affecting adolescents. Obesity is one risk factor, and as this is increasing the incidence of SUFE is likely to rise. Diagnosis and treatment are usually straightforward and carried out by orthopaedic surgeons. However, the recognition of post-treatment complications poses a much greater challenge. This article focuses on possible complications of surgical treatment of SUFE particularly. Chondrolysis, avascular necrosis, as well as other complications of treatment and conditions leading to premature osteoarthritis are discussed. Checklists for a systematic approach to post-treatment imaging are provided.

    The following problems are analysed referring to the literature and to practical experience of the authors: - Types of complications encountered in contrast roentgenography or in endoscopy of the colon, and their frequency. - Risk factors and secondary injuries. Intestinal perforation is the most frequent complication experienced as a consequence of contrast barium enema. The main risk factors are to be seen in the use of balloon-tipped catheters, or of intestinal tubes with hard tips, in a rise of hydrostatic pressure above 80 cm water column, and in an excessively strong air insufflation. Frequency of complications for contrast barium enema is stated to be 0.002 p.c. (Welin and Welin, 1980) or 0.08 p.c. (Clark et al. 1961). The frequency of perforations in rectoscopy is shown to be in the same order of magnitude. For diagnostic colonoscopy, the frequency of complications is about one per mil. Existing diseases such as carcinoma, diverticulosis, diverticulitis, colitis ulcerosa, or morbus Crohn are factors enhancing the risk. Also, patients of advanced age are running a higher risk due to decreasing intestine wall elasticity with age. Previous biopsy or excision forbids contrast barium enema for the next two weeks. Injuries and sequelae to be expected after perforation are abscesses, phlegmon, peritonitis including formation of adhesion and bands, retroperitoneal fibrosis with formation of hydronephrosis, and anus praeter, the latter being temporary or permanent. An extensive literature survey covering 200 publications has been prepared and is available from the authors upon request. (orig.) [de

    Definitions of complicated grief vary across diagnostic systems, being represented as persistent complex bereavement (PCB) in DSM-5 and prolonged grief disorder (PGD) in the proposed revision of the ICD system. A past study in a high-income country has identified a six-factor structure for complicated grief, but there are no data testing this or any other model across cultures. The present study reports findings from a survey amongst West Papuan refugees (n = 230, response rate = 92 %) residing in Port Moresby, Papua New Guinea. We applied culturally adapted measures of conflict-related traumatic event (TEs) (drawing specifically on domains of conflict and loss), symptoms of complicated grief adapted and modified to the culture, and a multidimensional psychosocial index of the broader effects of conflict and displacement. Confirmatory factor analysis yielded a single higher order construct of complicated grief comprising six factors of yearning/preoccupation; shock/disbelief; anger/negative appraisal; behavioural change; estrangement from others/impairment; and a novel dimension of confusion/diminished identity. In contrast, our analysis failed to support DSM or ICD models of PCB or PGD. A Multiple Indicators Multiple Causes (MIMIC) model revealed that traumatic loss and the sense of injustice each were associated with the unitary construct of complicated grief and its subdomains of yearning/preoccupation; shock/disbelief; anger/negative appraisal (exclusive to injustice); and estrangement from others/social impairment (exclusive to TE domain of conflict and loss). Conflict and loss associated with feelings of injustice may be especially pathogenic in generating the anger/negative appraisal component of complicated grief amongst refugees.

    The authors describe the sequelae and urinary complications of: - radiotherapy only in 524 patients, stage I to III treated between 1960 and 1974; - 721 operations performed between 1968 and 1974, according to the protocol of treatment as used in the Fondation Curie. This reveals: - for irradiated patients, no iatrogenic damage to the upper urinary tract, whilst bladder complications were often present. No major complication was found in this group; - for operated patients, the surgical act was without harmful consequence in the 672 cases when the operation was foreseen in the initial protocol (0.6% of chief complications). On the other hand, surgery performed for persistent tumour or recurrence after exclusive radiotherapy showed 8% of chief complications. In this group they analyse the factors that might influence ureterohydronephroses, especially the extent of node dissection and associated external irradiation [fr

    Full Text Available Introduction Despite the advent of antibiotics and immunizations in the last century, complications of otitis media remain quite frequent, have high morbidity and mortality rates, and pose a challenge to the otorhinolaryngologist. Objective To establish the annual incidence of intratemporal complications of otitis media and prospectively evaluate patients via an analysis of epidemiologic and clinical aspects. Methods Prospective, observational study. Between February 2010 and January 2011, patients admitted to a tertiary care, university-based otology practice with diagnosis of otitis media and an associated intratemporal complication (ITC were included in the study. The following data were evaluated: age, sex, type of ITC, treatment, imaging tests findings, type and degree of hearing loss, and clinical outcome. The overall incidence of all complications and of each complication individually was determined. Results A total of 1,816 patients were diagnosed with otitis media. For 592 (33% individuals, the diagnosis was chronic otitis media; for 1,224 (67%, the diagnosis was acute otitis media. ITCs of otitis media were diagnosed in 15 patients; thus, the annual incidence of intratemporal complications was 0.8%. We identified 19 ITC diagnoses in 15 patients (3 patients had more than one diagnosis. Labyrinthine fistulae were diagnosed in 7 (36.8% individuals, mastoiditis in 5 (26.3%, facial palsy in 4 (21.1%, and labyrinthitis in 3 (15.8%. Conclusion The incidence of intratemporal complications in Brazil remains significant when compared with developed countries. Chronic otitis media with cholesteatoma is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

  8. Preventing microvascular complications in type 1 diabetes mellitus

    Full Text Available Patients with complications of diabetes such as retinopathy, nephropathy, and cardiovascular complications have increased hospital stay with greater economic burden. Prevention of complications should be started before the onset of type 1 diabetes mellitus (T1DM by working on risk factors and thereafter by intervention upon confirmatory diagnosis which can prevent further damage to β-cells. The actual risk of getting microvascular complications like microalbuminuria and retinopathy progression starts at glycated hemoglobin (HbA1c level of 7%. As per the American Diabetes Association, a new pediatric glycemic control target of HbA1c 20 years as compared to patients <10 years of age. Screening of these complications should be done regularly, and appropriate preventive strategies should be followed. Angiotensin converting enzyme inhibitors and angiotensin II receptor blocker reduce progression from microalbuminuria to macroalbuminuria and increase the regression rate to normoalbuminuria. Diabetic microvascular complications can be controlled with tight glycemic therapy, dyslipidemia management and blood pressure control along with renal function monitoring, lifestyle changes, including smoking cessation and low-protein diet. An integrated and personalized care would reduce the risk of development of microvascular complications in T1DM patients. The child with diabetes who receives limited care is more likely to develop long-term complications at an earlier age. Screening for subclinical complications and early interventions with intensive therapy is the need of the hour.

    The most effective therapy in patients with limited-stage small cell lung cancer (LS SCLC) seems to be chemotherapy (using platinum-based regimens) and thoracic radiotherapy (TRT), which is followed by prophylactic cranial irradiation. The analysed group comprised 217 patients who received combined treatment for LS SCLC, i.e. chemotherapy (according to cisplatin and etoposide schedule) and TRT (concurrent in 101 and sequential in 116 patients). The influence of chemoradiotherapy (ChT-RT) schedule on treatment results (frequency of complete response, survival rates, and incidence of treatment failure and complications) was evaluated, and the frequency and severity of pulmonary complications were analysed to identify risk factors. The 5-year survival rates in concurrent vs. sequential ChT-RT schedules were 27.3 vs. 11.7% (overall) and 28 vs. 14.3% (disease-free). The frequencies of adverse events in relation to concurrent vs. sequential therapy were 85.1 vs. 9.5% (haematological complications) and 58.4 vs. 38.8% (pulmonary fibrosis), respectively. It was found that concurrent ChT-RT (hazard ratio, HR 2.75), a total dose equal to or more than 54 Gy (HR 2.55), the presence of haematological complications (HR 1.89) and a lung volume receiving a dose equal to or greater than 20 Gy exceeding 31% (HR 1.06) were the risk factors for pulmonary complications. Pulmonary complications after ChT-RT developed in 82% of patients treated for LS SCLC. In comparison to the sequential approach, concurrent ChT-RT had a positive effect on treatment outcome. However, this is a factor that can impair treatment tolerance, which manifests in the appearance of side effects. (orig.)

    Full Text Available Background: Vitamin D has important actions on glucose metabolism. These include improved insulin exocytosis, direct stimulation of insulin receptor, improved uptake of glucose by peripheral tissues, improving insulin resistance. It has got various pleiotropic effects like suppression of cell mediated immunity, regulation of cell proliferation, stimulation of neurotropic factors such as nerve growth factor, Glial cell line-derived neurotrophic factor, neurotropin, suppression of RAAS, reduction of albuminuria, immunomodulatory effects, and anti-inflammatory effects. Thus, vitamin D is implicated in many ways in the pathogenesis of retinopathy, neuropathy and nephropathy. Objectives: To study the correlation of vitamin D levels with microvascular complications in type 2 diabetes. Materials and Methods: Cross-sectional case-control study of 18 patients (18-70 years, who met the American Diabetes Association 2011 criteria for type 2 diabetes, was conducted. Age and sex matched healthy controls were taken. Subjects were evaluated for the presence of microvascular complications by clinical evaluation, urine examination, fundus examination, nerve conduction studies, and various biochemical tests. 25-OH cholecalciferol levels were done for each. Cut off level for vitamin D deficiency was 20 ng/ml. Results: Mean vitamin D was lower in type 2 diabetics than healthy subjects (19.046 vs. 27.186 ng/ml. Prevalence of vitamin D deficiency and insufficiency was found to significantly higher in diabetics when compared to healthy subjects (P = 0.0001. Vitamin D deficiency was found to be significantly associated with neuropathy (χ2 = 5.39, df = 1, P = 0.020, retinopathy, (χ2 = 6.6, df = 1, P = 0.010 and nephropathy (χ2 = 10. 52, df = 1, P = 0.001.

    The routine dental practice involves various dental procedures which needs the application of local anesthetics. Generally, there are very few complications associated with these procedures. Complications such as tissue necrosis can occur following the rapid injection of local anesthetic solutions. Palate is a favorable site for soft tissue lesions, various factors such as direct effects of the drug, blanching of the tissues during injection, a relatively poor blood supply, and reactivation of the latent forms of herpes can all promote to tissue ischemia and a lesion in the palate.

    Malignancy is a secondary cause of sarcopenia, which is associated with impaired cancer treatment outcomes. The aim of this study was to investigate the prevalence of preoperative sarcopenia among elderly gastric cancer patients undergoing gastrectomy and the differences in preoperative dietary intake and postoperative complications between sarcopenic and non-sarcopenic patients. Ninety-nine patients over 65 years of age who underwent gastrectomy for gastric cancer were analyzed. All patients underwent gait and handgrip strength testing, and whole-body skeletal muscle mass was measured using a bioimpedance analysis technique based on the European Working Group on Sarcopenia in Older People (EWGSOP) algorithm for the evaluation of sarcopenia before surgery. Preoperative dietary intake was assessed using a food frequency questionnaire. Of these patients, 21 (21.2 %) were diagnosed with sarcopenia. Sarcopenic patients consumed fewer calories and less protein preoperatively (23.9 vs. 27.8 kcal/kg ideal weight/day and 0.86 vs. 1.04 g/kg ideal weight/day; P = 0.001 and 0.0005, respectively). Although the overall incidence of postoperative complications was similar in the two groups (57.1 % vs. 35.9 %; P = 0.08), the incidence of severe (Clavien-Dindo grade ≥ IIIa) complications was significantly higher in the sarcopenic group than in the non-sarcopenic group (28.6 % vs. 9.0 %; P = 0.029). In the multivariate analysis, sarcopenia alone was identified as a risk factor for severe postoperative complications (odds ratio, 4.76; 95 % confidence interval, 1.03-24.30; P = 0.046). Preoperative sarcopenia as defined by the EWGSOP algorithm is a risk factor for severe postoperative complications in elderly gastric cancer patients undergoing gastrectomy.

    In acromegaly the long-term exposure to high growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels may result in specific complications in different human organs, including the thyroid gland and the colon. We will review here the evidence available regarding the characteristic thyroid and colon complications in acromegaly. This review summarizes the published data observing noncancerous structural abnormalities (thyroid nodules, colonic polyps) and thyroid and colon cancer in patients diagnosed with acromegaly. Thyroid micro-carcinomas are probably over-diagnosed among acromegalic patients. In regard to colon cancer, there is no sufficient data to suggest that colon cancer risk is higher in acromegaly compared to the general population.

    Purpose: To evaluate the incidence and causes of complications associated with balloon-occluded arterial infusion chemotherapy (BOAI) for pelvic malignancies. Methods: In 34 courses of BOAI in 22 patients with pelvic malignancies, we analyzed the incidence of complications as well as the effect of the dose of the anticancer drugs, the infusion site, and the number of BOAI administrations on these complications. Complications were divided into two categories: cystitis-like symptoms and neurological complications such as pain, numbness, and paresthesia of the lower extremities and the hip. Results: Eleven patients (50%) suffered from complications, seven (31.8%) from neurological complications and four (18.2%) from cystitis-like symptoms. The complications appeared in 14 courses (42.4%) of BOAI, neurological complications in 10 (30.3%) and cystitis-like symptoms in four (12.1%). A high dose of anti-cancer drugs and infusion from the anterior division tended to induce neurological complications more frequently; however, the cystitis-like symptoms were not related to any factors. Conclusion: Our results indicate that a smaller dose of anti-cancer drugs should be infused from the bilateral internal iliac arteries for safer pelvic BOAI

    Full Text Available Abstract Background Cerebrovascular complications are severe events following orthotopic liver transplantation (OLT. This study aimed to observe the clinical and neuroimaging features and possible risk factors of in-hospital cerebrovascular complications in the patients who underwent OLT. Patients and methods We retrospectively reviewed 337 consecutive patients who underwent 358 OLTs. Cerebrovascular complications were determined by clinical and neuroimaging manifestations, and the possible risk factors were analyzed in the patients with intracranial hemorrhage. Results Ten of 337 (3.0% patients developed in-hospital cerebrovascular complications (8 cases experienced intracranial hemorrhage and 2 cases had cerebral infarction, and 6 of them died. The clinical presentations were similar to common stroke, but with rapid deterioration at early stage. The hematomas on brain CT scan were massive, irregular, multifocal and diffuse, and most of them were located at brain lobes and might enlarge or rebleed. Infarcts presented lacunar and multifocal lesions in basal gangliar but with possible hemorrhagic transformation. The patients with intracranial hemorrhage had older age and a more frequency of systemic infection than non-intracranial hemorrhage patients. (P = 0.011 and 0.029, respectively. Conclusion Posttransplant cerebrovascular complications have severe impact on outcome of the patients who received OLT. Older age and systemic infection may be the possible risk factors of in-hospital intracranial hemorrhage following OLT.

    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.

    Objective: To evaluate multislice CT in the diagnosis of biliary complications after liver transplantation. Methods: Eighty-three consecutive patients who had undergone orthotopic liver transplantation (OLT) presented with clinical or biochemical signs of biliary complications and underwent contrast-enhancement CT examination. Three experienced radiologists, who were blinded to patient's clinical data, assessed CT images for the detection of biliary complications in consensus. Diagnostic confirmation of biliary complications was obtained with direct cholangiography in 69 patients, histologic study in 11 patients and hepaticojejunostomy in 3 patients. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT for the detection of biliary complications were calculated. In addition, CT features of anastomotic biliary stricture (ABS) were compared with those of non-anastomotic biliary stricture (NABS) using χ 2 test. Results: A total of 62 biliary complications (74.7%) was eventually confirmed in the 83 patients, including ABS in 32 patients, NABS in 21 patients, biliary duct stones in 16 patients (of which 12 patients with biliary stricture) , anastomotic bile leakage in 5 patients, biloma in 4 patients with biliary stricture, and biliogenic abscess in 2 patients with biliary stricture. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT for the detection of biliary stricture were 90.6%, 86.7%, 89.2%, 92.3% and 83.9%, respectively. Other biliary complications, including biliary duct stones (16 cases), anastomotic bile leak (5 cases), biloma (4 cases), and biliogenic abscess (2 cases), were correctly diagnosed by CT; there was no false-positive or false-negative result. The incidence of irregular dilatation of bile duct was 71.4% (15/21), which was significantly higher in NABS cases than in ABS of 25.0% (8/32, P<0.01); whereas the incidence of extrahepatic biliary dilatation

    1995-02-01

    Software reliability is especially important to customers these days. The need to quantify software reliability of safety-critical systems has been received very special attention and the reliability is rated as one of software's most important attributes. Since the software is an intellectual product of human activity and since it is logically complex, the failures are inevitable. No standard models have been established to prove the correctness and to estimate the reliability of software systems by analysis and/or testing. For many years, many researches have focused on the quantification of software reliability and there are many models developed to quantify software reliability. Most software reliability models estimate the reliability with the failure data collected during the test assuming that the test environments well represent the operation profile. User's interest is on the operational reliability rather than on the test reliability, however. The experiences show that the operational reliability is higher than the test reliability. With the assumption that the difference in reliability results from the change of environment, testing environment factor comprising the aging factor and the coverage factor are defined in this work to predict the ultimate operational reliability with the failure data. It is by incorporating test environments applied beyond the operational profile into testing environment factor Test reliability can also be estimated with this approach without any model change. The application results are close to the actual data. The approach used in this thesis is expected to be applicable to ultra high reliable software systems that are used in nuclear power plants, airplanes, and other safety-critical applications

    To identify the predictors of symptomatic post-radiation T2 signal change in patients with arteriovenous malformations (AVM) treated with radiosurgery. The charts of 211 consecutive patients with arteriovenous malformations treated with either gamma knife radisurgery or linear accelerator radiosurgery between 2000-2009 were retrospectively reviewed. 168 patients had a minimum of 12 months of clinical and radiologic follow-up following the procedure and complete dosage data. Pretreatment characteristics and dosimetric variables were analyzed to identify predictors of adverse radiation effects. 141 patients had no clinical symptomatic complications. 21 patients had global or focal neurological deficits attributed to symptomatic edema. Variables associated with development of symptomatic edema included a non-hemorrhagic symptomatic presentation compared to presentation with hemorrhage, p=0.001; OR (95%CI) = 6.26 (1.99, 19.69); the presence of venous rerouting compared to the lack of venous rerouting, p=0.031; OR (95% CI) = 3.25 (1.20, 8.80); radiosurgery with GKS compared to linear accelerator radiosurgery p = 0.012; OR (95% CI) = 4.58 (1.28, 16.32); and the presence of more than one draining vein compared to a single draining vein p = 0.032; OR (95% CI) = 2.82 (1.06, 7.50). We postulated that the higher maximal doses used with gamma knife radiosurgery may be responsible for the greater number of adverse radiation effects with this modality compared to linear accelerator radiosurgery. We found that AVMs with greater venous complexity and therefore instability resulted in more adverse treatment outcomes, suggesting that AVM angioarchitecture should be considered when making treatment decisions.

    The objectives of this study are to determine the prevalence, risk factors, and time to onset of delayed hemothorax and pneumothorax in adults who experienced a minor blunt thoracic trauma. A prospective cohort of 450 consecutive patients was recruited. Eligible patients had to be over 16 years of age, consulted within 72 hours for a trauma, and available for outpatient follow-up at 2, 7, and 14 days posttrauma. The clinical outcome investigated was the presence of delayed pneumothorax or hemothorax on the follow-up chest x-ray. Delayed hemothorax occurred in 11.8% (95% CI 8.8-14.8), and delayed pneumothorax occurred in 0.9% (95% CI 0.2-2.3) of participants. During the 14-day follow-up period, 87.0% of these delayed complications developed in the first week. In the multivariate analysis, the only statistically significant risk factor for delayed complications was the location of fractures on the x-ray of the hemithorax. The adjusted odds ratio was 1.52 (95% CI 0.62-3.73) for the lower ribs (tenth to twelfth rib), 3.11 (95% CI 1.60-6.08) for the midline ribs (sixth to ninth rib), and 5.05 (95% CI 1.80-14.19) for the upper ribs (third to fifth rib) versus patients with no fractures. The presence of at least one rib fracture between the third and ninth rib on the x-ray of the hemithorax is a significant risk factor for delayed hemothorax and pneumothorax.

    The acquisition of data and public discussion of complications after therapeutic procedures and surgeries is a sensitive subject, which is mostly avoided even in department meetings. However, it is evident that the broad discussion and the expression of different opinions and aspects provide useful information for continuous improvements. Therefore, we established a system for the transparent acquisition of complications in our department. Since January 2005, we systematically register operative and non-operative complications at our department, evaluate them and therefore gain a great benefit. All the complications are presented, discussed and evaluated within the weekly morbidity and mortality conferences. In 2005 and 2006, among a total number of 2730 and, respectively, 3124 operations, 102 (3.7 %) and 71 (2.3 %) complications have been registered and analysed according to different criteria. We have distinguished between complications which required surgery and complications which only required conservative treatment. There was a higher number of complications which needed surgery. In this group, the most common complications have been found in vertebral spine surgery. The groups of complications with conservative treatment were mostly related to nerve lesions and deep venous thrombosis. With the aid of the internal department evaluation of the registered data, especially the number of complications in vertebral spine surgery could be clearly reduced in 2006. The described method has created a transparency of occurring complications because each colleague is informed as well as involved in the solution process. Furthermore, it is planned to evaluate the impact of risk factors on the various performed surgeries. © Georg Thieme Verlag KG Stuttgart · New York.

  8. Ultrasound-Guided Interscalene Catheter Complicated by Persistent Phrenic Nerve Palsy

    2018-01-01

    Full Text Available A 76-year-old male presented for reverse total shoulder arthroplasty (TSA in the beach chair position. A preoperative interscalene nerve catheter was placed under direct ultrasound-guidance utilizing a posterior in-plane approach. On POD 2, the catheter was removed. Three weeks postoperatively, the patient reported worsening dyspnea with a subsequent chest X-ray demonstrating an elevated right hemidiaphragm. Pulmonary function testing revealed worsening deficit from presurgical values consistent with phrenic nerve palsy. The patient decided to continue conservative management and declined further invasive testing or treatment. He was followed for one year postoperatively with moderate improvement of his exertional dyspnea over that period of time. The close proximity of the phrenic nerve to the brachial plexus in combination with its frequent anatomical variation can lead to unintentional mechanical trauma, intraneural injection, or chemical injury during performance of ISB. The only previously identified risk factor for PPNP is cervical degenerative disc disease. Although PPNP has been reported following TSA in the beach chair position without the presence of a nerve block, it is typically presumed as a complication of the interscalene block. Previously published case reports and case series of PPNP complicating ISBs all describe nerve blocks performed with either paresthesia technique or localization with nerve stimulation. We report a case of a patient experiencing PPNP following an ultrasound-guided placement of an interscalene nerve catheter.

    Q-switched (QS) lasers are the gold standard for tattoo removal. The purpose of the present study was to gain a more comprehensive understanding of the factors that influence the efficacy of QS lasers and their associated complications in the removal of tattoos in China. Clinical data of 266 patients were analyzed retrospectively. The tattoo clearance rate was evaluated using the 4-point scale. The Cox regression model was applied to analyze the factors that affected the efficacy of QS lasers in tattoo removal. In addition, treatment-related adverse reactions were analyzed. The results showed that several variables had a statistically significant effect (p tattoo removal treatment, including the patients' age, the tattoo's age, type, color, or ink density and the number of treatments. A variety of adverse responses occurred during the laser treatment. The overall incidence of adverse responses was approximately 24.06%, including pigmentation, hypopigmentation, bulla formation, allergic reactions, and skin texture changes or hypertrophic scarring. Some factors may influence the efficacy of QS lasers in the treatment of tattoos and certain adverse reactions may occur during this process.

    Full Text Available Introduction: The aim of the research was to investigate incidence, risk factors, and complications associated with emergency peripartum hysterectomy, the ultimate treatment method for intractable postpartum hemorrhage. Methods: This is a single center case-control study conducted in Chongqing city in central China from 1st January 2007 to 31st December 2012 for emergency peripartum hysterectomy performed as a treatment of postpartum hemorrhage both in caesarean and vaginal delivery cases. While the study group included emergency peripartum hysterectomy (n=61 due to intractable postpartum hemorrhage, the control group included no hysterectomy (n=333 during the same study period. Results: We found 61 cases recorded for emergency peripartum hysterectomy for intractable postpartum hemorrhage. Incidence of peripartum hysterectomy was 2.2 per 1000 deliveries. Emergency peripartum hysterectomy as treatment of intractable postpartum hemorrhage include the followings: (i blood loss 1000-2000 ml, crude odd ratio (OR =18.48 (95% CI 5.1-65.7, adjusted odd ratio (AOR = 9.1 (95% CI 2.2-37.7; (ii blood loss >2000 ml, OR = 152 (95% CI 43.7-528.4, AOR = 45.3 (95% CI 11.6-176.9; (iii previous caesarean section, OR = 5.5 (95% CI 2.9-9.7, AOR = 3.7(95% CI 1.4-9.9; (iv uterine atony, OR = 11.9 (95% CI 5.8-24.6, AOR = 7.5 (95% CI 1.8-30.2; (v placenta previa, OR = 2.04 (95% CI 1.1-3.5, AOR = none. Conclusions: Emergency peripartum hysterectomy is the last resort as treatment of intractable severe postpartum hemorrhage. Our study depicts that severe post partum hemorrhage, further dreaded complex events for emergency peripartum hysterectomy, has significant association with placental factors, previous caesarean section, and uterine atony. Pathologically, placenta accreta remained the most leading cause of hysterectomy. Keywords: caesarean section; hemorrhage; peripartum hysterectomy; placenta previa.

    To evaluate the frequency of short-term pulmonary complications in the patients undergoing various head and neck cancer surgeries in our setup and to assess possible risk factors responsible for these complications. Seventy patients of age group 20 to 80 years, regardless of gender, treated surgically for head and neck cancers were enrolled. Main outcome measures included development of pulmonary complications following 15 days of oncological surgery. The complications studied were pneumothorax, bronchopneumonia, atelectasis, pulmonary embolism and cardiopulmonary arrest. A total of 24.28% patients suffered from postoperative pulmonary complications; 17.14% developed bronchopneumonia, 5.71% pulmonary embolism, and 1.42% went into cardiopulmonary arrest, none developed pneumothorax or pulmonary atelectasis. A significant correlation of postoperative bronchopneumonia was seen with heavy smoking and assisted ventilation. Pulmonary embolism was associated with extended assisted ventilation and prolonged surgery. Cardiopulmonary arrest was associated with comorbidity and assisted ventilation after surgery. The frequency of bronchopneumonia supersedes all of the postoperative pulmonary complications in head and neck oncological surgery. Patients at risk of developing postoperative complications are heavy smokers, diabetics, those undergoing prolonged surgery, tracheostomy, and extended assisted ventilation. (author)

    2017-06-01

    Full Text Available Objective: It is known that Pseudomonas has been isolated more frequently in health care-related urinary tract infections (UTIs. It was aimed to determine the risk factors and empiric therapies due to antibiotic resistance in Pseudomonas-related male UTIs, and assess the effect of Pseudomonas isolation on treatment and length of hospital stay. Materials and Methods: The study was conducted between January 2011 and January 2013 with 228 male health care-related complicated UTI patients hospitalized in the Urology and Infectious Diseases Inpatient Clinics at Gazi University Faculty of Medicine. Three hundred UTI attacks in 228 patients were evaluated retrospectively with regard to agents. Results: Pseudomonas was isolated in 37 of 300 complicated UTI attacks in 228 male patients. Nephrolithiasis, recurrent UTI and internal urinary catheterization were determined as the risk factors for Pseudomonas related with health care-related UTI. It was understood that nephrolithiasis increased Pseudomonas isolated UTI risk 3.5 fold and recurrent UTI increased the risk 8.9 fold. The antibiotic resistance of Pseudomonas was higher than other agents. Pseudomonas related UTIs prolonged the duration of hospital stay and antibiotic treatment. Conclusion: In the presence of nephrolithiasis, recurrent UTI and internal urinary catheterization, drugs against Pseudomonas would be appropriate empiric treatment for health care-related complicated UTI. Ciprofloxacin use should be restricted when local antibiotic resistance, which leads empiric treatment, is taken into consideration. Increases in hospital stay and antibiotic treatment duration were thought to be associated with recurrent infection frequency and high antibiotics resistance in Pseudomonas related UTIs.

    Hospital-specific electronic health record systems are used to inform clinical practice about best practices and quality improvements. Many surgical centers have developed deterministic clinical decision rules to discover adverse events (e.g. postoperative complications) using electronic health record data. However, these data provide opportunities to use probabilistic methods for early prediction of adverse health events, which may be more informative than deterministic algorithms. Electronic health record data from a set of 9598 colorectal surgery cases from 2010 to 2014 were used to predict the occurrence of selected complications including surgical site infection, ileus, and bleeding. Consistent with previous studies, we find a high rate of missing values for both covariates and complication information (4-90%). Several machine learning classification methods are trained on an 80% random sample of cases and tested on a remaining holdout set. Predictive performance varies by complication, although an area under the receiver operating characteristic curve as high as 0.86 on testing data was achieved for bleeding complications, and accuracy for all complications compares favorably to existing clinical decision rules. Our results confirm that electronic health records provide opportunities for improved risk prediction of surgical complications; however, consideration of data quality and consistency standards is an important step in predictive modeling with such data.

    Full Text Available Background: Information on factors associated with birth preparedness and complication readiness (BP/CR is central in designing cost effective programs for reducing maternal deaths among women. This study assessed factors influencing BP/CR among pregnant women attending antenatal clinic in Ogbomoso, South West Nigeria. Methodology: This is a cross-sectional study conducted between January and April, 2015. Systematic sampling technique was employed to recruit 400 women attending antenatal clinic at Bowen University Teaching Hospital, Ogbomoso, Nigeria. A pre-tested questionnaire was used for data collection and data analysis was done using SPSS version 21. Chi-square test was used for bivariate analysis while binary logistic regression was used for multivariate analysis. Statistical significance was set at p <0.05. Results: More than half (51.3% of our respondents were in the 30-39 age category. Only 40.3% of these respondents were reported well prepared for births and were complication ready. The proportion of women who had BP/CR was significantly higher among those in the middle socio-economic group (51.6%, p<0.05, those who practiced Christianity (76.4%, p<0.05 and those from Yoruba ethnic group (80.1%, p<0.05. Respondents in lower socio-economic group were 42% less likely to have prepared for birth compared to women in the high socio-economic class (OR: 0.58, 95% CI: 0.34-0.99. Conclusion and Global Health Implications: The proportion of Nigerian women in our sample who were well-prepared for birth and its complication was below average. There is need for more awareness programs on BP/CR; such programs should target all women especially the vulnerable group

    The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. Prospective descriptive study. In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. Of the 570 patients undergoing laparoscopic surgery, 17 (3%) had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI) was the most frequent (n = 10, 1.8%), followed by port site bleeding (n = 4, 0.7%), omentum-related complications (n = 2; 0.35%), and port site metastasis (n = 1, 0.175%). Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit.

    The purpose of this study was to determine the incidence and risk factors of infections associated with implantable venous access ports (IVAPs.) From August 2003 through November 2011, 1747 IVAPs were placed in our interventional radiology suite. One hundred forty four IVAPs were inserted in patients with hematologic malignancy and 1603 IVAPs in patients with solid tumors. Among them, 40 ports (23 women and 17 men; mean age, 57.1 years; range, 13-83) were removed to treat port-related infections. We evaluated the incidence of port-related infection, patient characteristics, bacteriologic data, and patient progress. Univariable analyses (t test, chi-square test, and Fisher's exact test) and multiple logistic regression analyses were used to determine the risk factors for IVAP related infection. Overall, 40 (2.3%) of 1747 ports were removed for symptoms of infection with an incidence rate of 0.067 events/1000 catheter-days. According to the univariable study, the incidences of infection were seemingly higher in the patients who received the procedure during inpatient treatment (p = 0.016), the patients with hematologic malignancy (p = 0.041), and the patients receiving palliative chemotherapy (p = 0.022). From the multiple binary logistic regression, the adjusted odds ratios of infection in patients with hematologic malignancies and those receiving palliative chemotherapy were 7.769 (p = 0.001) and 4.863 (p = 0.003), respectively. Microorganisms were isolated from 26 (65%) blood samples, and two of the most causative organisms were found to be Staphylococcus (n = 10) and Candida species (n = 7). The underlying hematologic malignancy and the state of receiving palliative chemotherapy were the independent risk factors of IVAP-related infection.

    2015-01-01

    Purpose: Some investigators have reported severe rectal complications after brachytherapy. Due to the low number of such events, their relationship to dosimetric parameters has not been well characterized. Methods and materials: A total of 3126 patients were treated with low dose rate brachytherapy from 1998 through 2010. 2464 had implant alone, and 313 had implant preceded by 44–46 Gy supplemental external beam radiation (EBRT). Post-implant dosimetry was based on a CT scan obtained on the day of implant, generally within 30 min of the procedure. Every patient’s record was reviewed for occurrence of rectal complications. Results: Eight of 2464 patients (0.32%) treated with brachytherapy alone developed a radiation-related rectal fistula. Average prostatic and rectal dose parameters were moderately higher for fistula patients than for patients without a severe rectal complication. For instance, the average R100 was 1.2 ± 0.75 cc for fistula patients, versus 0.37 ± 0.88 cc for non-fistula patients. However, the fistula patients’ values were well within the range of values for patients without a rectal complication. Four patients had some attempt at repair or reconstruction, but long-term functional outcomes were not favorable. Conclusions: Rectal fistulas are a very uncommon potential complication of prostate brachytherapy, which can occur even in the setting of acceptable day 0 rectal doses. Their occurrence is not easily explained by standard dosimetric or clinical factors

    Full Text Available Abstract Background To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB. Methods A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any abdominal complication, including its incidence, characters, relative risks, diagnostic measures, medical or surgical management and mortality, was retrospectively analyzed. Results Of all the patients, 33(1.4% developed abdominal complications postoperatively, including 11(33.3% cases of paralytic ileus, 9(27.3% of gastrointestinal haemorrhage, 2(6.1% of gastroduodenal ulcer perforation, 2(6.1% of acute calculus cholecystitis, 3(9.1% of acute acalculus cholecystitis, 4(12.1% of hepatic dysfunction and 2(6.1% of ischemia bowel diseases. Of the 33 patients, 26 (78.8% accepted medical treatment and 7 (21.2% underwent subsequent surgical intervention. There were 5(15.2% deaths in this series, which was significantly higher than the overall mortality (2.7%. Positive history of peptic ulcer, advanced ages, bad heart function, preoperative IABP support, prolonged CPB time, low cardiac output and prolonged mechanical ventilation are the risk factors of abdominal complications. Conclusions Abdominal complications after cardiovascular surgery with CPB have a low incidence but a higher mortality. Early detection and prompt appropriate intervention are essential for the outcome of the patients.

    Full Text Available The purpose of this study is to show how a private eye care center in Turkey initiated Six Sigma principles to reduce the number of complications encountered during and after intravitreal injections. Data were collected for 30-months. To analyse the complications among 229 injections administered on 106 patients, main tools of Six Sigma’s Define-Measure-Analyze-Improve-Control (DMAIC improvement cycle such as SIPOC table, Fishbone Diagram and, Failure, Mode and Effect Analysis were implemented. Sources and root causes of seven types of complications were identified and reported. For a successful intravitreal injection, experience of the retina specialist, attention of the retina specialist and patient’s ocular pathology were determined to be the “critical few” factors whereas, sterilization and hygiene, dosage of drug/agent and chemical properties of drug/agent were found to be the “trivial many”factors. The most frequently occuring and the complication with the highest hazard score was found to be subconjunctival haemorrhage. The process sigma level of the process was measured to be 3.2657. The surgical team concluded that six of the complications (out of seven should be significantly reduced by taking the necessary preventative measures.

    We investigated the prognostic role of high MICs for antistaphylococcal agents in patients with methicillin-sensitive Staphylococcus aureus catheter-related bloodstream infection (MSSA CRBSI). We prospectively reviewed 83 episodes from 5 centers in Spain during April 2011–June 2014 that had optimized clinical management and analyzed the relationship between E-test MICs for vancomycin, daptomycin, oxacillin, and linezolid and development of complicated bacteremia by using multivariate analysis. Complicated MSSA CRBSI occurred in 26 (31.3%) patients; MICs for vancomycin and daptomycin were higher in these patients (optimal cutoff values for predictive accuracy = 1.5 μg/mL and 0.5 μg/mL). High MICs for vancomycin (hazard ratio 2.4, 95% CI 1.2–5.5) and daptomycin (hazard ratio 2.4, 95% CI 1.1–5.9) were independent risk factors for development of complicated MSSA CRBSI. Our data suggest that patients with MSSA CRBSI caused by strains that have high MICs for vancomycin or daptomycin are at increased risk for complications. PMID:27192097

    Full Text Available Nasogastric tube has a key role in the management of substantial number of hospitalized patients particularly the critically ill. In spite of the apparent simple insertion technique, nasogastric tube placement has its serious perhaps fatal complications which need to be carefully assessed. Pulmonary misplacement and associated complications are commonplace during nasogastric tube procedure. We present a case of tension pneumothorax and massive surgical emphysema in critically ill ventilated patient due to inadvertent nasogastric tube insertion and also discussed the risk factors, complication list, and arrays of techniques for safer tube placement.

    Purpose: The current study was conducted to investigate the incidence and risk factors for medical complications associated with low dose rate brachytherapy in patients with medically inoperable Stage I endometrial cancer treated with irradiation alone. Methods and Materials: From 1965 through 1991 at Mallinckrodt Institute of Radiology, 150 implants were performed on 96 patients who were deemed medically unfit for hysterectomy because of advanced age, obesity, and various medical problems. The records of these patients were examined retrospectively to determine the incidence of medical complications that occurred in the first 30 days following the initiation of brachytherapy. The association of risk factors that precluded major surgery and the occurrence of brachytherapy-related complications was examined by logistic regression. Results: Of these 96 patients, 40 patients were older than 75 years, and 31 patients were deemed morbidly obese. Medical problems included hypertension in 45 patients, and diabetes in 37; there was a history of congestive heart failure in 23, stroke in 11, myocardial infarction in 10, and thromboembolism in 8. There were concurrent malignancies in five patients. Implants were performed using intrauterine Simon-Heyman capsules, tandems, and vaginal ovoids in all patients. General anesthesia was used for 98 implants, spinal anesthesia for 26, local anesthesia for 25, and epidural anesthesia for 1. The duration of anesthesia ranged from 30 to 120 min (median, 60 min). The duration of radioisotope application ranged from 11 to 96 h (median, 46 h). Preventive measures included low dose subcutaneous heparin in 55 patients (since 1978), and intermittent pneumatic compression boots in 29 (since 1985). Four patients developed life-threatening complications including myocardial infarction (two patients), congestive heart failure (one patient), and pulmonary embolism (one patient). Two of these four patients died; one with a myocardial infarction and

    Spirometry is a basic test that provides much information about pulmonary function; it is performed preoperatively in almost all patients undergoing colorectal cancer (CRC) surgery in our hospital. However, the value of spirometry as a preoperative test for CRC surgery remains unknown. The aim of this study was to determine whether spirometry is useful to predict postoperative complications (PCs) after CRC surgery. The medical records of 1236 patients who had preoperative spirometry tests and underwent CRC surgery between 2005 and 2014 were reviewed. Preoperative spirometry results, such as forced vital capacity (FVC), one-second forced expiratory volume (FEV1), %VC (FVC/predicted VC) and FEV1/FVC (%FEV1), were analyzed with regard to PCs, including pneumonia. PCs were found in 383 (30.9%) patients, including 218 (56%) with surgical site infections, 67 (17%) with bowel obstruction, 62 (16%) with leakage and 20 (5.2%) with pneumonia. Of the spirometry results, %VC was correlated with PC according to logistic regression analysis (odds ratio, OR = 0.99, 95% confidence interval, CI = 0.98-0.99; P = 0.034). Multivariate analysis after adjusting for male sex, age, laparoscopic surgery, tumor location, operation time and blood loss showed that a lower %VC tends to be a risk factor for PC (OR = 0.99, 95% CI = 0.98-1.002; P = 0.159) and %VC was an independent risk factor for postoperative pneumonia in PCs (OR = 0.97, 95% CI = 0.94-0.99; P = 0.049). In CRC surgery, %VC may be a predictor of postoperative complications, especially pneumonia. © The Author 2017. Published by Oxford University Press. All rights reserved.

    Full Text Available Introduction:Cardiovascular diseases are the most frequent causes of morbidity and mortality in patients with chronic renal disease. The aim of our paper is to evaluate the risk factors of cardiovascular complications in patients with various stages of chronic renal disease (CRD, with or without diabetes mellitus (DM.Patients and methods:The study included 98 patients with different stages of the CRD, with creatinine clearance <60 ml/min/1,73m2, and laboratory parameters monitored: homocysteine, BNP, cholesterol, LDL, HDL, HbA1c, Body Mass Index (BMI. First group comprised 49 patients with DM, age 50-82 years, M 28/F 21. Second group comprised 49 patients without DM, age 35-80 years, M 18/F 31. The IMT (intima media thickness was measured by B-mode ultrasonography, and all patients had echocardiography examination done by 2D Doppler ultrasonography.Results:The IMT values in diabetic patients had statistically significant positive correlation with homocysteine values of r=0,9393, p<0,034, and cholesterol r=0,289, p<0,05, compared to non-diabetics. A significant negative correlation was found between the ejection fraction (EF and BMI in both groups, more prominent in non-diabetics r=0,289, p<0,044 (diabetics r=0,162, p>0,05. 47,4% of diabetics had arteriosclerotic changes on carotid arteries, 8,5% had stenosis of ACC, and 22,0% had rhythm abnormalities on ECG. A positive correlation between IMT and BMI was found in diabetics, but was not statistically significant r=0,111, p>0,05. In the diabetics group a significantly higher (p<0,05 values of BNP, HbA1c, proteinuria, BMI, and cholesterol were found, and significantly lowered EF (p<0,0001.Conclusion:Risk factors for cardiovascular complications in patients with DM are various, and the most pronounced significance was found in the values of homocystein, BNP and cholesterol.

    Full Text Available Objective. This prospective study was undertaken to evaluate pregnant women's willingness to undergo HSV type-specific serologic testing and factors affecting willingness in an obstetrics/gynecology ambulatory unit. Methods. At prenatal Visit 1, pregnant women (n=303 with no history of HSV-2 were tested for HSV-1/HSV-2 before and after they received counseling on genital and neonatal herpes. Results. In both the Unwilling Subgroup and the group that changed from being willing to being unwilling, the most common reasons for choosing not to be tested were not being at risk for genital herpes, being tested is too personal, and concern about what will be done with the results. Of the 134 participants in the Willing/Tested Subgroup, 27 (20% were HSV-2 seropositive and 81 (60% were HSV-1 seropositive. Conclusions. These results support the feasibility of HSV serologic testing and counseling in pregnant women.

    PurposeCryoablation of renal tumors is assumed to have a higher risk of hemorrhagic complications compared to other ablative modalities. Our purpose was to establish the exact risk and to identify hemorrhagic risk factors.Materials and MethodsThis IRB approved, 7-year prospective study included 261 renal cryoablations. Procedures were under conscious sedation and CT guidance. Pre- and postablation CT was obtained, and hemorrhagic complications were CTCAE tabulated. Age, gender, tumor size, histology, and probes number were tested based on averages or proportions using their exact permutation distribution. “High-risk” subgroups (those exceeding the thresholds of all variables) were tested for each variable alone, and for all combinations of variable threshold values. We compared the subgroup with the best PPV using one variable, with the subgroup with the best PPV using all variables (McNemmar test).ResultsThe hemorrhagic complication rate was 3.5 %. Four patients required transfusions, two required emergent angiograms, one required both a transfusion and angiogram, and two required bladder irrigation for outlet obstruction. Perirenal space hemorrhage was more clinically significant than elsewhere. Univariate risks were tumor size >2 cm, number of probes >2, and malignant histology (P = 0.005, 0.002, and 0.033, respectively). Multivariate analysis showed that patients >55 years with malignant tumors >2 cm requiring 2 or more probes yielded the highest PPV (7.5 %).ConclusionsAlthough older patients (>55 years old) with larger (>2 cm), malignant tumors have an increased risk of hemorrhagic complications, the low PPV does not support the routine use of embolization. Percutaneous cryoablation has a 3.5 % risk of significant hemorrhage, similar to that reported for other types of renal ablative modalities.

    2017-07-04

    BACKGROUND Rhabdomyolysis is a syndrome caused by muscle breakdown. It can be caused by traumatic as well as non-traumatic factors such as drugs, toxins, and infections. Although it has been initially associated with only traumatic causes, non-traumatic causes now appear to be at least 5 times more frequent. In rhabdomyolysis, the CK levels can range anywhere from 10 000 to 200 000 or even higher. The higher the CK levels, the greater will be the renal damage and associated complications. We present the case of a patient with exceptionally massive rhabdomyolysis with unusually high CK levels (nearly 1 million) caused by combined etiologic factors and complicated with acute renal failure. CASE REPORT A 36-year-old African American male patient with no significant past medical history and a social history of cocaine and alcohol abuse presented with diarrhea and generalized weakness of 2 days' duration. He was found to be febrile, tachycardic, tachypneic, and hypoxic. The patient was subsequently intubated and admitted to the medical ICU. Laboratory work-up showed acute renal failure with deranged liver functions test results, and elevated creatine kinase of 701,400 U/L. CK levels were subsequently too high for the lab to quantify. Urine legionella testing was positive for L. pneumophilia serogroup 1 antigen and urine toxicology was positive for cocaine. The patient had a protracted course in the ICU. He was initially started on CVVH, and later received intermittent hemodialysis for about 1 month. CONCLUSIONS In the presence of multiple etiologic factors, rhabdomyolysis can be massive with resultant significant morbidity. Clinicians should have a high index of suspicion for rhabdomyolysis in the presence of multiple factors, as early recognition of this diseases is very important in the prevention and active management of life-threatening conditions.

    A number of evidence-based interventions have been proposed to reduce post-cesarean delivery wound complications. Examples of such interventions include appropriate timing of preoperative antibiotics, appropriate choice of skin antisepsis, closure of the subcutaneous layer if subcutaneous depth is ≥2 cm, and subcuticular skin closure with suture rather than staples. However, the collective impact of these measures is unclear. We sought to estimate the impact of a group of evidence-based surgical measures (prophylactic antibiotics administered before skin incision, chlorhexidine-alcohol for skin antisepsis, closure of subcutaneous layer, and subcuticular skin closure with suture) on wound complications after cesarean delivery and to estimate residual risk factors for wound complications. We conducted a secondary analysis of data from a randomized controlled trial of chlorhexidine-alcohol vs iodine-alcohol for skin antisepsis at cesarean delivery from 2011-2015. The primary outcome for this analysis was a composite of wound complications that included surgical site infection, cellulitis, seroma, hematoma, and separation within 30 days. Risk of wound complications in women who received all 4 evidence-based measures (prophylactic antibiotics within 60 minutes of cesarean delivery and before skin incision, chlorhexidine-alcohol for skin antisepsis with 3 minutes of drying time before incision, closure of subcutaneous layer if ≥2 cm of depth, and subcuticular skin closure with suture) were compared with those women who did not. We performed logistic regression analysis limited to patients who received all the evidence-based measures to estimate residual risk factors for wound complications and surgical site infection. Of 1082 patients with follow-up data, 349 (32.3%) received all the evidence-based measures, and 733 (67.7%) did not. The risk of wound complications was significantly lower in patients who received all the evidence-based measures compared with those who

    The present study tested whether various sociodemographic, anthropometric, behavioral, and medical/physiological factors act in a direct or indirect manner on the risk of prematurity using path analysis on a sample of Israeli births. The path model shows that medical complications, primarily toxemia, chorioammionitis, and a previous low birth weight delivery directly and significantly act on the risk of prematurity as do low maternal pregnancy weight gain and ethnicity. Other medical complications, including chronic hypertension, preclampsia, and placental abruption, although significantly correlated with prematurity, act indirectly on prematurity through toxemia. The model further shows that the commonly accepted sociodemographic, anthropometric, and behavioral risk factors act by modifying the development of medical complications that lead to prematurity as opposed to having a direct effect on premature delivery. © 1996 Wiley-Liss, Inc.

    PurposeTo report hepatic arterial-related complications encountered during planning and treatment angiograms for radioembolization and understand any potential-associated risk factors.Materials and Methods518 mapping or treatment angiograms for 180 patients with primary or metastatic disease to the liver treated by Yttrium-90 radioembolization between 2/2010 and 12/2015 were retrospectively reviewed. Intra-procedural complications were recorded per SIR guidelines. Patient demographics, indication for treatment, prior exposure to chemotherapeutic agents, operator experience, and disease burden were reviewed. Technical variables including type of radioembolic (glass vs. resin microspheres), indication for angiography (mapping vs. treatment), variant anatomy, and attempts at coil embolization were also assessed.ResultsThirteen (13/518, 2.5%) arterial-related complications occurred in 13 patients. All but two complications resulted during transcatheter coil embolization to prevent non-target embolization. Complications included coil migration (n = 6), arterial dissection (n = 2), focal vessel perforation (n = 2), arterial thrombus (n = 2), and vasospasm prohibiting further arterial sub-selection (n = 1). Transarterial coiling was identified as a significant risk factor of complications on both univariate and multivariate regression analysis (odds ratio 7.8, P = 0.004). Usage of resin microspheres was also a significant risk factor (odds ratio 9.5, P = 0.042). No other technical parameters or pre-procedural variables were significant after adjusting for confounding on multivariate analysis (P > 0.05).ConclusionIntra-procedural hepatic arterial complications encountered during radioembolization were infrequent but occurred mainly during coil embolization to prevent non-target delivery to extra-hepatic arteries.

    To assess retinal complications and to identify risk factors for retinal complications following aqueous shunt procedures. Records of 38 consecutive aqueous shunt procedures that were performed on 36 patients at the Eye Institute of the Medical College of Wisconsin, Milwaukee, from June 1993 to March 1995 (minimum follow-up, 6 months) were reviewed. The mean +/- SD follow-up was 11.4 +/- 5.2 months (median, 10.5 months). Twelve patients (32%) had the following retinal complications: 4 serous choroidal effusions (10%) that required drainage, 3 suprachoroidal hemorrhages (8%), 2 vitreous hemorrhages (5%), 1 rhegmatogenous retinal detachment (3%), 1 endophthalmitis (3%), and 1 scleral buckling extrusion (3%). Surgical procedures for retinal complications were required in 8 (67%) of these 12 patients. Visual acuity decreased 2 lines or more in 9 (75%) of these 12 patients. The median onset of a postoperative retinal complication was 12.5 days, with 10 patients (83%) experiencing complications within 35 days. Serous choroidal effusions developed in 10 other patients (26%), and these effusions resolved spontaneously. Visual acuity decreased 2 lines or more in 2 (20%) of these additional 10 patients. Patients who experienced serious retinal complications were significantly older, had a higher rate of hypertension, and postoperative ocular hypotony. Serious retinal complications were distributed evenly among patients with Krupin valves with discs and Molteno and Baerveldt devices. Experience with the Ahmed glaucoma valve implant was limited. Aqueous shunt procedures may be associated with significant retinal complications and subsequent visual loss.

    To determine inpatient and outpatient tracheostomy complication rates and 30-day hospital readmission rates, and to assess patient and procedural risk factors associated with complications and readmissions. Prospective cohort study. Adult patients undergoing tracheostomy at a single academic hospital performed by any service, for any indication, were enrolled in this study over the course of 1 year. All patients had complete 30-day follow-up after discharge to determine complication and hospital readmission rates. Logistic regression was used to assess patient and procedural risk factors associated with these events. One hundred patients were enrolled in this study from June 1, 2015, to June 1, 2016. The overall inpatient tracheostomy complication rate was 47% (95% confidence interval [CI], 37%-57%). Inpatient complications were associated with location in the medical intensive care unit and increased length of hospitalization. The outpatient tracheostomy complication rate was 15% (95% CI, 8%-22%). Outpatient complications were associated with having a previous tracheostomy or an awake tracheostomy under local anesthesia. The all-cause 30-day hospital readmission rate was 33% (95% CI, 24%-42%), and the tracheostomy-specific readmission rate was 13% (95% CI, 6%-20%). All-cause readmissions were associated with diabetes, length of hospitalization after tracheostomy, and outpatient complications. The overall mortality rate during the study period was 11% (95% CI, 5%-17%), with one tracheostomy-related death. Patients undergoing tracheostomies are at high risk for both inpatient and outpatient complications, as well for 30-day hospital readmission. Understanding patient and procedural risk factors associated with these events will help guide interventions for quality improvement. 2b.

    Full Text Available Objective: To analyze individuals with spinal cord injury who developed secondary clinical complications, and the variables that can influence the prognosis. Methods: A prospective study of 321 patients with spinal cord injury. The variables were collected: age, sex, cause of the accident, anatomical distribution, neurological status, associated injuries, in-hospital complications, and mortality only in patients who developed complications. Results: A total of 72 patients were analyzed (85% male with a mean age of 44.72±19.19 years. The individuals with spinal cord injury who developed clinical complications were mostly male, over 50 years of age, and the main cause was accidental falls. These patients had longer hospitalization times and a higher risk of progressing to death. Pneumonia was the main clinical complication. With regard to the variables that can influence the prognosis of these patients, it was observed that spinal cord injury to the cervical segment with syndromic quadriplegia, and neurological status ASIA-A, have a higher risk of developing pneumonia, the most common complication, as well as increased mortality. Conclusion: Clinical complications secondary to spinal cord injury are influenced by demographic factors, as well as characteristics of the injury contributing to an increase in mortality.

    Graves' disease (GD) is an autoimmune thyroid disease with complex and not fully established etiology. It occurs when environmental factors influence people genetically prone to this illness. The aim of this study was to determine the impact of selected factors (endogenous and environmental) on the course and complications of disease in patients with recurrent GD. Two hundred and four patients with relapsed GD, treated in the Clinical Department of Endocrinology in University Hospital in Cracow in years 2004-2006 and then in 2011 were retrospectively analyzed. Patients who agreed to participate in the study were sent questionnaire to complete. Demographic and clinical data were collected and entered into a database. Patient data included: gender, place of living, lifestyle (smoking), family history of autoimmune diseases, the course of the disease, its symptoms and the treatment strategy. Furthermore the medical documentation was analyzed. Descriptive statistical analyses were made. The study showed a significant difference in the frequency of appearance of ophthalmopathy between men and women (80% and 37.14%, respectively, p = 0.041), between smokers and nonsmokers (61.9% and 21.05%, respectively, p = 0.022) and between the age of patients with positive and negative family history of autoimmune diseases (37.6 years and 50.5 years respectively, p = 0.002). 1. Male gender is a risk factor for ophthalmopathy in GD. 2. Cigarette smoking affects the risk of Graves' ophthalmopathy. 3. A positive family history of thyroid diseases and/or autoimmune diseases promotes the development of GD at a younger age.

    Full Text Available Context: The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. Aims: To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. Settings and Design: Prospective descriptive study. Materials and Methods: In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. Statistical Analysis Used: Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. Results: Of the 570 patients undergoing laparoscopic surgery, 17 (3% had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI was the most frequent (n = 10, 1.8%, followed by port site bleeding (n = 4, 0.7%, omentum-related complications (n = 2; 0.35%, and port site metastasis (n = 1, 0.175%. Conclusions: Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit.

    Inbred Wistar-Kyoto rats consistently display hypoactivity in tests of emotional behavior. We used them to test the hypothesis that the genetic factors underlying the behavioral decision-making process will vary in different environmental contexts. The contexts used were the open-field test (OFT), a novel environment with no explicit threats present, and the defensive-burying test (DB), a habituated environment into which a threat has been introduced. Rearing, a voluntary behavior was measured in both tests, and our study was the first to look for genetic loci affecting grooming, a relatively automatic, stress-responsive stereotyped behavior. Quantitative trait locus analysis was performed on a population of 486 F2 animals bred from reciprocal inter-crosses. The genetic architectures of DB and OFT rearing, and of DB and OFT grooming, were compared. There were no common loci affecting grooming behavior in both tests. These different contexts produced the stereotyped behavior via different pathways, and genetic factors seem to influence the decision-making pathways and not the expression of the behavior. Three loci were found that affected rearing behavior in both tests. However, in both contexts, other loci had greater effects on the behavior. Our results imply that environmental context's effects on decision-making vary depending on the category of behavior.

    To determine demographic and clinical features of patients with Acanthamoeba keratitis (AK) that are independent risk factors both for bad outcomes and for severe inflammatory complications (SIC). A retrospective audit of medical records of AK cases at Moorfields Eye Hospital from July 2000 to April 2012, including 12 earlier surgical cases. Cases with a bad outcome were defined as those having one or more of the following: corneal perforation, keratoplasty, other surgery (except biopsy), duration of antiamoebic therapy (AAT) ≥10.5 months (the 75th percentile of the whole cohort) and final visual acuity ≤20/80. SICs were defined as having scleritis and/or a stromal ring infiltrate. Multivariable analysis was used to identify independent risk factors for both bad outcomes and SICs. Records of 194 eyes (194 patients) were included, having bad outcomes in 93 (48%). Bad outcomes were associated with the presence of SIC, aged >34 years, corticosteroids used before giving AAT and symptom duration >37 days before AAT. The development of SIC was independently associated with aged >34 years, corticosteroids used before giving AAT and herpes simplex virus (HSV) keratitis treatment before AAT. The prompt diagnosis of AK, avoidance of a misdiagnosis of HSV keratitis and corticosteroid use before the exclusion of AK as a potential cause of keratitis are essential to the provision of a good outcome for patients and for the avoidance of SIC. Older age is an unmodifiable risk factor that may reflect differences in the immune response to AK in this patient subset. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  5. Prevention of the Musculoskeletal Complications of Hemophilia

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Hemophilia is an inherited disorder of clotting factor deficiencies resulting in musculoskeletal bleeding, including hemarthroses, leading to musculoskeletal complications. The articular problems of hemophiliac patients begin in infancy. These include: recurrent hemarthroses, chronic synovitis, flexion deformities, hypertrophy of the growth epiphyses, damage to the articular cartilage, and hemophilic arthropathy. The most commonly affected joints are the ankle, the knee, and the elbow. Hematologic prophylactic treatment from ages 2 to 18 years could avoid the development of hemophilic arthropathy if the concentration of the patient's deficient factor is prevented from falling below 1% of normal. Hemarthroses can be prevented by the administration of clotting factor concentrates (prophylaxis. However, high costs and the need for venous access devices in younger children continue to complicate recommendations for universal prophylaxis. Prevention of joint arthropathy needs to focus on prevention of hemarthroses through prophylaxis, identifying early joint disease through the optimal use of cost-effective imaging modalities and the validation of serological markers of joint arthropathy. Screening for effects on bone health and optimal management of pain to improve quality of life are, likewise, important issues. Major hemarthrosis and chronic hemophilic synovitis should be treated aggressively to prevent hemophilic arthropathy.

    Infectious complications are, with rejection, the main cause of morbidity and mortality in heart transplantation recipients. Adequate management of these patients requires an adequate knowledge of risk factors, of most common infectious syndromes and of relevant microorganism, as long as of their resistance pattern. Among the first group, we may mention lower respiratory tract infections, mediastinitis and meningitis, and among the microorganisms, Citomegalovirus, Aspergillus and Toxoplasma gondii. The impressive development of diagnostical techniques and of prophylactic and therapeutical possibilities suggest the convenience of a multidisciplinar approach to these complications.

    To assess the incremental value of a single determination of the serum levels of sFlt-1 (soluble Fms-like tyrosine kinase 1) and PlGF (placental growth factor) or their ratio, without using cutoff values, for the prediction of maternal and fetal/neonatal complications and pregnancy prolongation, 620 women with suspected/confirmed preeclampsia, aged 18 to 48 years, were included in a prospective, multicenter, observational cohort study. Women had singleton pregnancies and a median pregnancy duration of 34 (range, 20-41) weeks. Complications occurred in 118 women and 248 fetuses. The median duration between admission and delivery was 12 days. To predict prolongation, PlGF showed the highest incremental value ( R 2 =0.72) on top of traditional predictors (gestational age at inclusion, diastolic blood pressure, proteinuria, creatinine, uric acid, alanine transaminase, lactate dehydrogenase, and platelets) compared with R 2 =0.53 for the traditional predictors only. sFlt-1 showed the highest value to discriminate women with and without maternal complications (C-index=0.83 versus 0.72 for the traditional predictors only), and the sFlt-1/PlGF ratio showed the highest value to discriminate fetal/neonatal complications (C-index=0.86 versus 0.78 for the traditional predictors only). Applying previously suggested cutoff values for the sFlt-1/PlGF ratio yielded lower incremental values than applying continuous values. In conclusion, sFlt-1 and PlGF are strong and independent predictors for days until delivery along with maternal and fetal/neonatal complications on top of the traditional criteria. Their use as continuous variables (instead of applying cutoff values for different gestational ages) should now be tested in a prospective manner, making use of an algorithm calculating the risk of an individual woman with suspected/confirmed preeclampsia to develop complications. © 2017 American Heart Association, Inc.

  12. Complications of bladder distension during retrograde urethrography.

    1981-05-01

    A severe, ulcerative cystitis that resulted in macroscopic hematuria occurred in 8 of 20 healthy dogs undergoing a series of diagnostic tests. Four of the remaining 12 dogs had mild bladder lesions consisting of submucosal edema and hemorrhage. Nine of the 20 dogs developed urinary tract infection after the procedures. These complications seemed associated with the radiographic technique of retrograde urethrography performed when the urinary bladder was distended. To test this hypothesis, retrograde urethrography was performed on 5 additional dogs. With the bladder undistended, no complications occurred. However, distention of these same dogs' bladders for 1 minute or less with sterile lactated Ringer's solution administered through a Foley catheter in the penile urethra resulted in a macroscopic hematuria in all 5 dogs which persisted for 24 hours. A microscopic hematuria continued for 5 days. One dog developed a bacterial urinary tract infection. A severe fibrinopurulent cystitis was present at necropsy of 2 dogs 2 days after distention. The morphologic changes in the bladder gradually diminished over 7 days, but mild submucosal edema and hemorrhage were still present when 2 dogs were necropsied, 7 days after distention. These studies indicated that retrograde urethrography in dogs may be complicated by hemorrhagic cystitis and urinary tract infection if performed with urinary bladder distention.

    Obstetric complications have predicted future development of schizophrenia in previous studies, but they are also more common in mothers with schizophrenia. The aims of this study were to compare the occurrence of obstetric complications in children of mothers with schizophrenia spectrum psychoses and control children, and to investigate whether obstetric complications predicted children's psychiatric morbidity. The Helsinki High-Risk (HR) Study monitors females born between 1916 and 1948 and treated for schizophrenia spectrum disorders in Helsinki psychiatric hospitals, their offspring born between 1941 and 1977, and controls. We examined information on obstetric complications and neonatal health of 271 HR and 242 control offspring. We compared the frequency of obstetric complications and neonatal health problems in the HR group vs controls and in HR children who later developed psychotic disorders vs healthy HR children. A Cox regression model was used to assess whether problems in pregnancy or delivery predicted psychiatric morbidity within the HR group. Few differences between HR and control offspring were found in obstetric complications. Within the HR group, infections (hazard rate ratio [HRR] 3.73, 95% CI 1.27-11.01), hypertension during pregnancy (HRR 4.10, 95% CI 1.15-14.58), and placental abnormalities (HRR 4.09, 95% CI 1.59-10.49) were associated with elevated risk of schizophrenia spectrum psychoses. Common medical problems during pregnancy were associated with increased risk of schizophrenia spectrum psychoses in offspring of mothers with schizophrenia spectrum psychoses. These results underline the role of the prenatal period in the development of schizophrenia and the importance of careful monitoring of pregnancies of mothers with psychotic disorder.

    Full Text Available Colonic complications of severe acute pancreatitis occur rarely. Although there have been several theories on how pancreatic pseudocysts rupture into the colon, the exact pathogenesis remains unknown. We report an unusual case of pseudocysts complicating severe acute pancreatitis presenting with colonic perforation in a 71-year-old man with a history of chronic mesenteric ischemia. Pressure effects from a giant pseudocyst and intravascular volume depletion with acute insult on chronic mesenteric ischemia are highlighted as possible etiologic factors.

    Objective: In the antibiotic era, purulent pericarditis is a rare entity. However, there are still reports of cases of the disease, which is associated with high mortality, and most such cases are attributed to delayed diagnosis. Approximately 40-50% of all cases of purulent pericarditis are caused by Gram-positive bacteria, Streptococcus pneumoniae in particular. Methods: We report four cases of pneumococcal pneumonia complicated by pericarditis, with different clinical features and levels of severity. Results: In three of the four cases, the main complication was cardiac tamponade. Microbiological screening (urinary antigen testing and pleural fluid culture) confirmed the diagnosis of severe pneumococcal pneumonia complicated by purulent pericarditis. Conclusions: In cases of pneumococcal pneumonia complicated by pericarditis, early diagnosis is of paramount importance to avoid severe hemodynamic compromise. The complications of acute pericarditis appear early in the clinical course of the infection. The most serious complications are cardiac tamponade and its consequences. Antibiotic therapy combined with pericardiocentesis drastically reduces the mortality associated with purulent pericarditis. (author)

    2017-09-01

    Full Text Available Background Among the various signs and symptoms of orbital fractures, certain clinical findings warrant immediate surgical exploration, including gaze restriction, computed tomographic (CT evidence of entrapment, and prolonged oculocardiac reflex. Despite proper surgical reconstruction, prolonged complications such as diplopia and gaze restriction can occur. This article evaluated the prognostic factors associated with prolonged complications of orbital fractures with muscle incarceration. Methods The medical records of 37 patients (37 orbits with an orbital fracture with muscle incarceration from January 2001 to January 2015 were reviewed. The presence of Incarcerated muscle was confirmed via CT, as well as by intraoperative findings. Various factors potentially contributing to complications lasting for over 1 year after the injury were categorized and analyzed, including age, cause of injury, injury-to-operation time, operative time, fracture type, nausea, vomiting and other concomitant symptoms and injuries. Results All patients who presented with extraocular muscle limitations, positive CT findings, and/or a positive forced duction test underwent surgery. Of the 37 patients, 9 (24% exhibited lasting complications, such as diplopia and gaze restriction. The mean follow-up period was 18.4 months (range, 1–108 months, while that of patients who experienced prolonged complications was 30.1 months (range, 13–36 months. Two factors were significantly associated with prolonged complications: injury-to-operation time and nausea/vomiting. Loss of vision, worsening of motility, and implant complication did not occur. Conclusions Patients who present with gaze limitations, with or without other signs of a blow-out fracture, require a thorough evaluation and emergent surgery. A better prognosis is expected with a shorter injury-to-operation time and lack of nausea and vomiting at the initial presentation.

    Type 2 Diabetes (T2D) is a chronic disease associated with a number of micro- and macrovascular complications that increase the morbidity and mortality of patients. The risk of diabetic complications has a strong genetic component. To this end, we sought to evaluate the association of 40 single nucleotide polymorphisms (SNPs) in 21 candidate genes with T2D and its vascular complications in 503 T2D patients and 580 healthy controls. The genes were chosen because previously reported to be associated with T2D complications and/or with the aging process. We replicated the association of T2D risk with I GF2BP rs4402960 and detected novel associations with TERT rs2735940 and rs2736098. The addition of these SNPs to a model including traditional risk factors slightly improved risk prediction. After stratification of patients according to the presence/absence of vascular complications, we found significant associations of variants in the CAT , FTO , and UCP1 genes with diabetic retinopathy and nephropathy. Additionally, a variant in the ADIPOQ gene was found associated with macrovascular complications. Notably, these genes are involved in some way in mitochondrial biology and reactive oxygen species regulation. Hence, our findings strongly suggest a potential link between mitochondrial oxidative homeostasis and individual predisposition to diabetic vascular complications.

    2017-07-01

    The objective of this study was to quantify complications associated with external skeletal fixators (ESFs) in cats and to identify potential risk factors. A retrospective review of medical records and radiographs following ESF placement was performed. Case records of 140 cats were reviewed; fixator-associated complications (FACs) occurred in 19% of cats. The region of ESF placement was significantly associated with complication development. Complications developed most frequently in the femur (50%), tarsus (35%) and radius/ulna (33%). Superficial pin tract infection (SPTI) and implant failure accounted for 45% and 41% of all FACs, respectively. SPTI occurred more frequently in the femur, humerus and tibia, with implant failure more frequent in the tarsus. No association between breed, age, sex, weight, fracture type (open vs closed), ESF classification, number of pins per bone segment, degree of fracture load sharing, and the incidence or type of FAC was identified. No association between region of placement, breed, age, sex, weight, fracture type (open vs closed), ESF classification, number of pins per bone segment, fracture load sharing and the time to complication development was identified. Complication development is not uncommon in cats following ESF placement. The higher complication rate in the femur, tarsus and radius/ulna should be considered when reviewing options for fracture management. However, cats appear to have a lower rate of pin tract infections than dogs.

    Twenty-seven children with acute leukemia were studied in order to detect the subsequent neurologic complications due to chemotherapy and radiation therapy. Twenty-four patients with ALL received central nervous system prophylaxis including cranial irradiation. The methods of evaluation consisted of electroencephalogram (EEG), computed tomography of the head (CT scan), soft neurological sign, intelligence quotient (IQ) and Bender Gestalt test. The patients with relapse showed severe abnormalities in various kinds of examinations. Younger children at diagnosis were associated with a higher abnormality rate of soft neurological signs and Bender Gestalt test. Factors which were found to be closely associated with a lower IQ score included younger children at diagnosis and longer duration of remission time. These results indicate the need for caution for the dosage of cranial irradiation for younger patients in CNS prophylaxis, and improvement of a lower IQ score in long-term survivors requires further investigation as to the appropriate intellectual environment for their development after remission.

The significant improvements in prognosis that have resulted from the use of these regimens, combined with the need for lifelong treatment, have increasingly focused attention on the adverse effects of antiretroviral drugs and on the metabolic complications of HIV protease inhibitors in particular. In this review, the cluster of metabolic abnormalities characterised by triglyceride-rich dyslipidaemia and insulin resistance associated with HIV protease inhibitor therapy are considered, along with implications for cardiovascular risk in patients affected by these complications. Toxicity profiles of individual drugs within the HIV protease inhibitor class are examined, as there is an increased recognition of significant intra-class differences both in terms of absolute risk of metabolic complications as well as the particular metabolic phenotype associated with these drugs. Guidelines for clinical assessment and treatment are emphasised, along with pathophysiological mechanisms that may provide a rational basis for the treatment of metabolic complications. Finally, these drug-specific effects are considered within the context of HIV-specific effects on lipid metabolism as well as lifestyle factors that have contributed to a rapidly increasing incidence of similar metabolic syndromes in the general population. These data highlight the importance of individualising patient management in terms of choice of antiretroviral regimen, assessment of metabolic outcomes and use of therapeutic interventions, based on the assessment of baseline (pre-treatment) metabolic status as well as the presence of potentially modifiable cardiovascular risk factors.

    To describe procedure-specific types, rates, and risk factors for postdischarge (PD) complications occurring within 30 days after 21 groups of inpatient general surgery procedures. Retrospective cohort study. American College of Surgeons National Surgical Quality Improvement Program 2005 through 2010 Participant Use Data Files. A total of 551,510 adult patients who underwent one of 21 groups of general surgery procedures in the inpatient setting. Postdischarge complications, reoperation, and mortality. Of 551,510 patients (mean age, 54.6 years), 16.7% experienced a complication; 41.5% occurred PD. Of the PD complications, 75.0% occurred within 14 days PD. Proctectomy (14.5%), enteric fistula repair (12.6%), and pancreatic procedures (11.4%) had the highest PD complication rates. Breast, bariatric, and ventral hernia repair procedures had the highest proportions of complications that occurred PD (78.7%, 69.4%, and 62.0%, respectively). For all procedures, surgical site complications, infections, and thromboembolic events were the most common. Occurrence of an inpatient complication increased the likelihood of a PD complication (12.5% vs 6.2% without an inpatient complication; P surgery; those whose PD complication was preceded by an inpatient complication had the highest rates of reoperation (33.7%) and death (24.7%) (all P < .001). After adjustment, PD complications were associated with procedure type, American Society of Anesthesiologists class higher than 3, and steroid use. The PD complication rates vary by procedure, are commonly surgical site related, and are associated with mortality. Fastidious, procedure-specific patient triage at discharge as well as expedited patient follow-up could improve PD outcomes.

    Biologic response modifiers, such as the interferons, are increasingly used in the treatment of cancer as an adjunct to conventional chemotherapy. In certain malignancies, particularly renal cell carcinoma, they are becoming agents of choice due to higher tumor response rate. The authors have reviewed 202 patients. Protocols include interferon, interleukin, tumor necrosis factor, and monoclonal antibodies. The radiology of significant clinical complications is discussed, especially the vascular leak syndrome often seen with interleukin administration and the cardiac toxicity of interferon. Less common abnormalities include progressive splenomegaly in one interferon study and a hemorrhagic episode caused by tumor necrosis factor

The peri- and postoperative complications are higher in total thyroidectomy (TT for SG than that for cervical goiter. The aim of this study was to evaluate the preoperative risk factors associated with postoperative complications. From 2002 to 2014, 142 (8.5%; 98 women and 44 men of the 1690 patients who underwent TT had a SG. We retrospectively evaluated the following parameters: sex, age, histology, pre- and retrovascular position, recurrence, and extension beyond the carina. These parameters were then related to the postoperative complications: seroma/hematoma, transient and permanent hypocalcemia, transient and permanent laryngeal nerve palsy, and the length of surgery. The results were further compared with a control group of 120 patients operated on in the same period with TT for cervical goiter. All but two procedures were terminated via cervicotomy, where partial sternotomies were required. No perioperative mortality was observed. Results of the statistical analysis (Student’s t-test and Fisher’s exact test indicated an association between recurrence and extension beyond the carina with all postoperative complications. The group that underwent TT of SG showed a statistically significant higher risk for transient hypocalcemia (relative risk =1.767 with 95% confidence interval: 1.131–2.7605, P=0.0124, and need to treat =7.1 and a trend toward significance for transient recurrent laryngeal nerve palsy (relative risk =6.7806 with 95% confidence interval: 0.8577–53.2898, P=0.0696, and need to treat =20.8 compared to the

    We present the case of a 49-year-old man who developed pulmonary abscess as a complication of transbronchial lung cryobiopsy. He had been receiving prednisone therapy, but otherwise had no specific risk factors for lung abscess. Cryobiopsy is a novel technique for obtaining peripheral lung parenchymal tissue for the evaluation of diffuse parenchymal lung diseases. Cryobiopsy is being increasingly proposed as an alternative to surgical lung biopsy or conventional bronchoscopic transbronchial forceps biopsy, but the safety profile of the procedure has not been fully appreciated. Pulmonary abscess has been rarely reported as a complication of other bronchoscopic procedures such as endobronchial ultrasound-guided needle biopsy, however, to our knowledge this is the first reported case of pulmonary abscess complicating peripheral lung cryobiopsy.

    Incisional hernia is a frequent complication after midline laparotomy. Surgical hernia repair is associated with complications, but no clear predictive risk factors have been identified. The European Hernia Society (EHS) classification offers a structured framework to describe hernias and to analyze postoperative complications. Because of its structured nature, it might prove to be useful for preoperative patient or treatment classification. The objective of this study was to investigate the EHS classification as a predictor for postoperative complications after incisional hernia surgery. An analysis was performed using a registry-based, large-scale, prospective cohort study, including all patients undergoing incisional hernia surgery between September 1, 2011 and February 29, 2016. Univariate analyses and multivariable logistic regression analysis were performed to identify risk factors for postoperative complications. A total of 2,191 patients were included, of whom 323 (15%) had 1 or more complications. Factors associated with complications in univariate analyses (p < 0.20) and clinically relevant factors were included in the multivariable analysis. In the multivariable analysis, EHS width class, incarceration, open surgery, duration of surgery, Altemeier wound class, and therapeutic antibiotic treatment were independent risk factors for postoperative complications. Third recurrence and emergency surgery were associated with fewer complications. Incisional hernia repair is associated with a 15% complication rate. The EHS width classification is associated with postoperative complications. To identify patients at risk for complications, the EHS classification is useful. Copyright © 2017.

    AIM: To audit the performance of our percutaneous nephrostomy service by comparing the major complication rate with the standards recommended by the Society of Cardiovascular and Interventional Radiology and the American College of Radiology: major haemorrhage in <4%, and septic shock in <4%. Secondary aims were to identify common sources of errors for quality improvement measures. METHODS: Major complications sustained between January 1997-December 2002 were identified. All cases had been carried out by the interventional radiology service of a large teaching hospital with the assistance of a nurse and radiographer, under fluoroscopic and ultrasound guidance using a Seldinger technique. Existing department protocols specified pre-procedure antibiotics for suspected infected cases and normal coagulation studies. From records and review of case notes pertinent clinical/procedural details and eventual outcome were assessed. The following were particularly noted: adherence to protocols, clinical status at time of procedure, delay in referral, complication sustained, signs of infection or coagulopathy, timing of procedure (in versus out of hours), level of operator and technical faults. RESULTS: Ten of 318 (3.1%) cases sustained a major complication: five had sepsis alone, two haemorrhage (one with sepsis as well) and three patients had a major pelvic injury (one with sepsis as well). Thus the major sepsis and haemorrhage rates were 2.2 and 0.6%, and were within the recommended threshold limits but proportionately more complications occurred out of hours: six of 105 (5.7%) versus four of 312 (1.8%; p=0.087). Sepsis was the most serious complication and may have contributed to the death of two patients. On individual case analysis, failed instrumentation with delay to definitive renal drainage was a common factor with sepsis; but the following were contributory factors in one or more cases: omitted antibiotics (in three of 10; two became septic), technical factors in

    Full Text Available Third molar surgery is the most common procedure performed by oral and maxillofacial surgeons worldwide. This article addresses the incidence of specific complications and, where possible, offers a preventive or management strategy. Complications, such as pain, dry socket, swelling, paresthesia of the lingual or inferior alveolar nerve, bleeding, and infection are most common. Factors thought to influence the incidence of complications after third molar removal include age, gender, medical history, oral contraceptives, presence of pericoronitis, poor oral hygiene, smoking, type of impaction, relationship of third molar to the inferior alveolar nerve, surgical time, surgical technique, surgeon experience, use of perioperative antibiotics, use of topical antiseptics, use of intra-socket medications, and anaesthetic technique. For the general dental practitioner, as well as the oral and maxillofacial surgeon, it is important to be familiar with all the possible complications after this procedure. This improves patient education and leads to prevention, early recognition and management.

    The purpose of this systematic review was to address the incidence of complications associated with wrist arthroscopy. Given the paucity of information published on this topic, an all-inclusive review of published wrist arthroscopy complications was sought. Two independent reviewers performed a literature search using PubMed, Google Scholar, EBSCO, and Academic Megasearch using the terms "wrist arthroscopy complications," "complications of wrist arthroscopy," "wrist arthroscopy injury," and "wrist arthroscopy." Inclusion criteria were (1) Levels I to V evidence, (2) "complication" defined as an adverse outcome directly related to the operative procedure, and (3) explicit description of operative complications in the study. Eleven multiple-patient studies addressing complications of wrist arthroscopy from 1994 to 2010 were identified, with 42 complications reported from 895 wrist arthroscopy procedures, a 4.7% complication rate. Four case reports were also found, identifying injury to the dorsal sensory branch of the ulnar nerve, injury to the posterior interosseous nerve, and extensor tendon sheath fistula formation. This systematic review suggests that the previously documented rate of wrist arthroscopy complications may be underestimating the true incidence. The report of various complications provides insight to surgeons for improving future surgical techniques. Level IV, systematic review of Levels I-V studies.

    Studies have shown that perinatal factors are associated with childhood asthma. The current analyses examined the association between obstetric complications and risk of asthma at the age of 7 years using a prospectively population-based birth cohort in northern Finland. Results indicated that obstetric complications were associated with a higher risk of asthma among children. Those children who were administered special procedures at birth, i.e., cesarean section, vacuum extraction, and other procedures, including use of forceps, manual auxiliary, and extraction breech, had an adjusted odds ratio (OR) for asthma of 1.38 (95% confidence interval [CI] 1.00-1.92), 1.32 (95% CI 0.80-2.19), and 2.14 (95% CI 1.06-4.33), respectively, as compared to children who were delivered normally. Children who had a lower Apgar score at the first and the fifth minute after birth also had a higher risk as compared to those who had an Apgar score of 9-10. The results encourage further evaluation of the association between obstetric complications and risk of asthma among children in other populations, and further exploration of possible mechanisms underlying the association.

    The received account of whistleblowing, developed over the last quarter century, is identified with the work of Norman Bowie and Richard DeGeorge. Michael Davis has detailed three anomalies for the received view: the paradoxes of burden, missing harm and failure. In addition, he has proposed an alternative account of whistleblowing, viz., the Complicity Theory. This paper examines the Complicity Theory. The supposed anomalies rest on misunderstandings of the received view or misreadings of model cases of whistleblowing, for example, the Challenger disaster and the Ford Pinto. Nevertheless, the Complicity Theory is important for as in science the contrast with alternative competing accounts often helps us better understand the received view. Several aspects of the received view are reviewed and strengthened through comparison with Complicity Theory, including why whistleblowing needs moral justification. Complicity Theory is also critiqued. The fundamental failure of Complicity Theory is its failure to explain why government and the public encourage and protect whistleblowers despite the possibility of considerable harm to the relevant company in reputation, lost jobs, and lost shareholder value.

    The coexistence of diabetes mellitus and hyperthyroidism has long been known and, in a few cases, diabetic acidosis complicated with thyroid storm has been reported. We describe a case who developed thyroid storm and diabetic ketoacidosis following /sup 131/I therapy for severe hyperthyroidism. A 50-yr-old man was diagnosed as having hyperthyroidism complicated with diabetes mellitus at the age of 47. After he had been unsuccessfully treated with methimazole and oral hypoglycemic agents, radioactive iodine was administered twice. However, no remarkable effect was observed. After a third treatment with /sup 131/I, the patient showed symptoms like thyroid storm and diabetic ketoacidosis. He was hospitalized on October 3, 1980. Adm of insulin and supportive therapy including correction of dehydration alleviated his symptoms after admission. Administration of methimazole normalized his thyroid function. A 75 g GTT and tolbutamide i.v. test revealed impaired secretion of endogenous insulin. The patient had a high level of serum T/sub 3/ and T/sub 4/ following /sup 131/I therapy, indicating that the released hormone caused a transient condition like thyroid storm, which led to deterioration of glucose metabolism as indicated in high levels of hemoglobin A1c. Diabetic acidosis is the precipitating factor for thyroid storm. Prompt treatment for diabetic ketoacidosis, therefore, might prevent the complications of life-threatening thyroid storm.

    The Battery of Reasoning Tests 5 (BPR-5) aims to assess the reasoning ability of individuals, using sub-tests with different formats and contents that require basic processes of inductive and deductive reasoning for their resolution. The BPR has three sequential forms: BPR-5i (for children from first to fifth grade), BPR-5 - Form A (for children from sixth to eighth grade) and BPR-5 - form B (for high school and undergraduate students). The present study analysed 412 questionnaires concerning BPR-5i, 603 questionnaires concerning BPR-5 - Form A and 1748 questionnaires concerning BPR-5 - Form B. The main goal was to test the uni-dimensionality of the battery and its tests in relation to items using the bi-factor model. Results suggest that the g factor loadings (extracted by the uni-dimensional model) do not change when the data is adjusted for a more flexible multi-factor model (bi-factor model). A general reasoning factor underlying different contents items is supported.

    Full Text Available Vascular problems are the most common complications in diabetes. Substantial evidence from epidemiological and pathophysiological studies show that hyperglycemia is a major risk factor for macrovascular complications in patients with diabetes. (--Epigallocatechin-3-gallate (EGCG, the major catechin derived from green tea, is known to exert a variety of cardiovascular beneficial effects. The protective effects of EGCG in diabetes are also evident. However, whether EGCG is beneficial against macrovascular complications that occur in diabetes remains unknown. Our previous studies demonstrated that treatment of EGCG inhibits high glucose-induced vascular smooth muscle cell proliferation and suppresses high glucose-mediated vascular inflammation in human umbilical vein endothelial cells. Therefore, we hypothesize that EGCG might be an effective potential candidate to reduce the macrovascular complications in diabetes.

    To estimate health resource utilization (HRU) associated with the management of pacemaker complications in various healthcare systems. Electrophysiologists (EPs) from four geographical regions (Western Europe, Australia, Japan, and North America) were invited to participate. Survey questions focused on HRU in the management of three chronic pacemaker complications (i.e. pacemaker infections requiring extraction, lead fractures/insulation breaches requiring replacement, and upper extremity deep venous thrombosis [DVT]). Panelists completed a maximum of two web-based surveys (iterative rounds). Mean, median values, and interquartile ranges were calculated and used to establish consensus. Overall, 32 and 29 panelists participated in the first and second rounds of the Delphi panel, respectively. Consensus was reached on treatment and HRU associated with a typical pacemaker implantation and complications. HRU was similar across regions, except for Japan, where panelists reported the longest duration of hospital stay in all scenarios. Infections were the most resource-intensive complications and were characterized by intravenous antibiotics days of 9.6?13.5 days and 21.3?29.2 days for pocket and lead infections respectively; laboratory and diagnostic tests, and system extraction and replacement procedures. DVT, on the other hand, was the least resource intensive complication. The results of the panel represent the views of the respondents who participated and may not be generalizable outside of this panel. The surveys were limited in scope and, therefore, did not include questions on management of acute complications (e.g. hematoma, pneumothorax). The Delphi technique provided a reliable and efficient approach to estimating resource utilization associated with chronic pacemaker complications. Estimates from the Delphi panel can be used to generate costs of pacemaker complications in various regions.

    To determine the factors affecting the development of complications and the outcomes of JJ stenting. The study included 220 patients (133 males and 87 females, mean age 39.5 years, SD 15.4) who had self-retaining JJ ureteric stents placed while in the authors' institution. Univariate and multivariate analyses were used to identify the significant variables affecting the development of complications and outcome of stenting (condition 'improved' or 'not improved'). Using a modified Clavien classification, there were grade I, II, IIIa, IIIb complications in 67 (30.4%), 39 (17.7%), two (0.9%) and 23 (10.5%) patients, respectively, and none of grades IVa, IVb and V. Loin pain (10.9%) and urinary tract infection (10.9%) were the most common complications, followed by dysuria (7.7%). There were significant complications requiring treatment in 29% of patients, and 71.4% of patients improved after stenting. On multivariate analysis the significant independent factor affecting the complication rate was the stent length (P = 0.016), and the significant independent factor affecting the 'improved' outcome was age (P = 0.014). Longer stents are associated with increased complication rates, and the older the patient the more likely they are to have a poor outcome after stenting. Future prospective multicentre studies with more patients are needed to confirm the present conclusions.

    Across many research domains, evidence for complicated grief as a distinct psychopathology continues to grow. Previous research from neuropsychology has shown an increased attentional bias to emotionally relevant stimuli in those suffering from complicated grief. This study furthers our understanding of the characteristics that distinguish complicated grief. We expand on previous research by (a) testing older adults, (b) excluding those with comorbid major depressive disorder, (c) using participant-chosen grief-related stimuli, and (d) using a married, nonbereaved control group. We recruited 76 older adults in 3 groups: spousally bereaved with complicated grief, spousally bereaved with noncomplicated grief, and nonbereaved controls. Performance on the Wisconsin Card Sorting Task, Digit Span Backwards, and the emotional counting Stroop was examined. Results indicate longer reaction time across 3 blocks of grief-related words in the complicated grief group but no difference across 3 blocks of the neutral words. The 3 groups performed comparably on the other neurocognitive tasks, indicating no cognitive differences in working memory or set shifting between groups. Furthermore, these effects of complicated grief generalize to older adults and appear independent of major depression. Complicated grief has cognitive interference as a neuropsychological component highlighting it as distinct from noncomplicated grief.

    As maternal deaths have decreased worldwide, increasing attention has been placed on the study of severe obstetric complications, such as hemorrhage, eclampsia, and obstructed labor, to identify where improvements can be made in maternal health. Though access to medical care is considered to be life-saving during obstetric emergencies, data on the factors associated with health care decision-making during obstetric emergencies are lacking. We aim to describe the health care decision-making process during severe acute obstetric complications among women and their families in rural Bangladesh. Using the pregnancy surveillance infrastructure from a large community trial in northwest rural Bangladesh, we nested a qualitative study to document barriers to timely receipt of medical care for severe obstetric complications. We conducted 40 semi-structured, in-depth interviews with women reporting severe acute obstetric complications and purposively selected for conditions representing the top five most common obstetric complications. The interviews were transcribed and coded to highlight common themes and to develop an overall conceptual model. Women attributed their life-threatening experiences to societal and socioeconomic factors that led to delays in seeking timely medical care by decision makers, usually husbands or other male relatives. Despite the dominance of male relatives and husbands in the decision-making process, women who underwent induced abortions made their own decisions about their health care and relied on female relatives for advice. The study shows that non-certified providers such as village doctors and untrained birth attendants were the first-line providers for women in all categories of severe complications. Coordination of transportation and finances was often arranged through mobile phones, and referrals were likely to be provided by village doctors.

  13. Systemic inflammation: a key factor in the pathogenesis of cardiovascular complications in obstructive sleep apnoea syndrome?

    Obstructive sleep apnoea syndrome (OSAS) is a highly prevalent disease and is recognised as a major public health burden. Large-scale epidemiological studies have demonstrated an independent relationship between OSAS and various cardiovascular disorders. The pathogenesis of cardiovascular complications in OSAS is not completely understood but a multifactorial aetiology is likely. Inflammatory processes have emerged as critical in the pathogenesis of atherosclerosis at all stages of atheroma formation. Increased levels of various circulating markers of inflammation including tumour necrosis factor alpha (TNFalpha), interleukin 6 (IL6), IL-8 and C-reactive protein (CRP) have been reported as associated with future cardiovascular risk. There is increasing evidence of elevated inflammatory markers in OSAS with a significant fall after effective treatment with continuous positive airway pressure. This evidence is particularly strong for TNFalpha, whereas studies on IL6 and CRP have yielded conflicting results possibly due to the confounding effects of obesity. Cell culture and animal studies have significantly contributed to our understanding of the underlying mechanisms of the association between OSAS and inflammation. Intermittent hypoxia, the hallmark of OSAS, results in activation of pro-inflammatory transcription factors such as nuclear factor kappa B (NF-kappaB) and activator protein (AP)-1. These promote activation of various inflammatory cells, particularly lymphocytes and monocytes, with the downstream consequence of expression of pro-inflammatory mediators that may lead to endothelial dysfunction. This review provides a critical analysis of the current evidence for an association between OSAS, inflammation and cardiovascular disease, discusses basic mechanisms that may be responsible for this association and proposes future research possibilities.

    Nonoperative management (NOM) of blunt splenic injuries has been widely accepted, and the application of splenic artery embolization (SAE) has become an effective adjunct to NOM. However, complications do occur after SAE. In this study, we assess the factors leading to the major complications associated with SAE. Focusing on the major complications after SAE, we retrospectively studied patients who received SAE and were admitted to 2 major referral trauma centers under the same established algorithm for management of blunt splenic injuries. The demographics, angiographic findings, and factors for major complications after SAE were examined. Major complications were considered to be direct adverse effects arising from SAE that were potentially fatal or were capable of causing disability. There were a total of 261 patients with blunt splenic injuries in this study. Of the 261 patients, 53 underwent SAE, 11 (21%) of whom were noted to have 12 major complications: 8 cases of postprocedural bleeding, 2 cases of total infarction, 1 case of splenic abscess, and 1 case of splenic atrophy. Patients older than 65 years were more susceptible to major complications after SAE. Splenic artery embolization is considered an effective adjunct to NOM in patients with blunt splenic injuries. However, risks of major complications do exist, and being elderly is, in part, associated with a higher major complication incidence. Copyright © 2011 Elsevier Inc. All rights reserved.

    The case presented is a drainage of empyema of the left pleural cavity complicated with the penetration of the lung parenchyma and perforation of the left pulmonary artery with drain displacement to the right pulmonary artery. The cause of complications has been shown along with the possible ways of conduct. Drainage of the pleural cavity is a primary surgery in the chest. The presence of pleural air or fluid is an indication for its implementation. This procedure usually has no complications. Time pressure, anatomical anomalies, changes of the topography in the course of co-morbidities are the factors allowing for the creation of many complications. The aim of the work is to remind about the technical performance of this simple surgical procedure and to note that its complications may directly threaten the life of the patient. This is the first case reported in Polish literature.

    The American College of Surgeons and the American Geriatrics Society have suggested that preoperative cognitive screening should be performed in older surgical patients. We hypothesized that unrecognized cognitive impairment in patients without a history of dementia is a risk factor for development of postoperative complications. We enrolled 211 patients 65 yr of age or older without a diagnosis of dementia who were scheduled for an elective hip or knee replacement. Patients were cognitively screened preoperatively using the Mini-Cog and demographic, medical, functional, and emotional/social data were gathered using standard instruments or review of the medical record. Outcomes included discharge to place other than home (primary outcome), delirium, in-hospital medical complications, hospital length-of-stay, 30-day emergency room visits, and mortality. Data were analyzed using univariate and multivariate analyses. Fifty of 211 (24%) patients screened positive for probable cognitive impairment (Mini-Cog less than or equal to 2). On age-adjusted multivariate analysis, patients with a Mini-Cog score less than or equal to 2 were more likely to be discharged to a place other than home (67% vs. 34%; odds ratio = 3.88, 95% CI = 1.58 to 9.55), develop postoperative delirium (21% vs. 7%; odds ratio = 4.52, 95% CI = 1.30 to 15.68), and have a longer hospital length of stay (hazard ratio = 0.63, 95% CI = 0.42 to 0.95) compared to those with a Mini-Cog score greater than 2. Many older elective orthopedic surgical patients have probable cognitive impairment preoperatively. Such impairment is associated with development of delirium postoperatively, a longer hospital stay, and lower likelihood of going home upon hospital discharge.

    Chest pain is the most common admission diagnosis for observation unit patients. These patients often undergo cardiac stress testing to further risk stratify for coronary artery disease (CAD). The decision of whom to stress is currently based on clinical judgment. We sought to determine the influence of cardiac risk factor burden on cardiac stress test outcome for patients tested from an observation unit, inpatient or outpatient setting. We performed a retrospective observational cohort study for all patients undergoing stress testing in our institution from June 2006 through July 2007. Cardiac risk factors were collected at the time of stress testing. Risk factors were evaluated in a summative fashion using multivariate regression adjusting for age and known coronary artery disease. The model was tested for goodness of fit and collinearity and the c statistic was calculated using the receiver operating curve. A total of 4026 subjects were included for analysis of which 22% had known CAD. The rates of positive outcome were 89 (12.0%), 95 (12.6%), and 343 (16.9%) for the OU, outpatients, and hospitalized patients respectively. While the odds of a positive test outcome increased for additional cardiac risk factors, ROC curve analysis indicates that simply adding the number of risk factors does not add significant diagnostic value. Hospitalized patients were more likely to have a positive stress test, OR 1.41 (1.10 - 1.81). Our study does not support basing the decision to perform a stress test on the number of cardiac risk factors.

    Creation of an arteriovenous fistula (AVF) is the preferred method of establishing long-term dialysis access. There are multiple anesthetic techniques used for patients undergoing this surgery including general endotracheal intubation, laryngeal mask airway, regional anesthesia with nerve blocks, and monitored anesthesia care with local infiltration. It is unclear what effect the method of anesthesia has on AVF creation success rate. It is our objective to determine if anesthesia type affects success of these surgeries defined by complication and maturation rates. A retrospective review was performed in a single institution, single surgeon study of 253 patients who underwent AVF creation between January 2003 and December 2010. Patients were cross analyzed between 3 anesthesia types (General Endotracheal Intubation, Laryngeal Mask Airway and Local Infiltration with Monitored Anesthesia Care) and AVF creation surgeries (radiocephalic, brachiocephalic, and basilic vein transposition). No patients had regional anesthesia performed. Demographic data including comorbidities and risk factors were stratified among all categories. Analysis of variance, chi-squared testing, and Fisher's exact P testing was performed across all anesthesia types and specific operations and measured according to success of fistula maturation and complication rates (including death within 30 days, myocardial infarction within 30 days, respiratory insufficiency, venous hypertension, wound infections, neuropathy, and vascular steal syndrome). There were no significant differences in maturation rate in terms of all 3 anesthesia types for radiocephalic (P = 0.191), brachiocephalic (P = 0.191), and basilic vein transposition surgeries (P = 0.305). In addition, there were no differences in complication rates between the surgeries and the 3 types of anesthesia (P = 0.557). Our study shows that despite anesthesia type, outcomes in terms of maturation and complication rate are not statistically

    Full Text Available Glucose variability has been identified as a potential risk factor for diabetic complications; oxidative stress is widely regarded as the mechanism by which glycemic variability induces diabetic complications. However, there remains no generally accepted gold standard for assessing glucose variability. Representative indices for measuring intraday variability include calculation of the standard deviation along with the mean amplitude of glycemic excursions (MAGE. MAGE is used to measure major intraday excursions and is easily measured using continuous glucose monitoring systems. Despite a lack of randomized controlled trials, recent clinical data suggest that long-term glycemic variability, as determined by variability in hemoglobin A1c, may contribute to the development of microvascular complications. Intraday glycemic variability is also suggested to accelerate coronary artery disease in high-risk patients.

    Earlier age at onset of psychosis (AOP) has been associated with poor social adjustment and clinical outcome. Genetic and environmental factors such as obstetric complications, parental history of psychosis, advanced paternal age at time of birth, low birth weight and gestational age, and use of drugs have been described as bringing AOP forward. This study aims to evaluate the relationship between AOP and these factors in a sample of first episode of psychosis (FEP) patients. Clinical and sociodemographic data, age at FEP, age of parents at birth, parental history of psychosis, drug-use habits of the mother during pregnancy and of the patient before psychotic onset, and Lewis and Murray obstetric complication scale were obtained from 90 patients with FEP. Statistical analysis was performed by means of Pearson correlations, Chi-square tests, Student T-test analyses and a linear regression model using SPSS version 22. Pre-eclampsia, need for incubator at birth, use of forceps, parental history of psychosis, and low birth weight were associated with an earlier AOP. Use of forceps and birth weight are the variables which best predict AOP in FEP. Stimulant drugs, which were mostly used together with cannabis and cocaine, were the only substances associated with an earlier AOP. Our findings are consistent with previous study results and underline the role of the prenatal period in the development of psychosis and the importance of careful monitoring of pregnancy and delivery, especially in cases with familial history.

    Full Text Available Sickle cell disease (SCD is one of the most common inherited diseases in the world and the patients present notorious clinical heterogeneity. It is known that patients with SCD present activation of the blood coagulation and fibrinolytic systems, especially during vaso-occlusive crises, but also during the steady state of the disease. We determined if the presence of the factor V gene G1691A mutation (factor V Leiden, the prothrombin gene G20210A variant, and methylenetetrahydrofolate reductase (MTHFR C677T polymorphism may be risk factors for vascular complications in individuals with SCD. We studied 53 patients with SCD (60% being women, 29 with SS (sickle cell anemia; 28 years, range: 13-52 years and 24 with SC (sickle-hemoglobin C disease; 38.5 years, range: 17-72 years hemoglobinopathy. Factor V Leiden, MTHFR C677T polymorphism, and prothrombin G20210A variant were identified by PCR followed by further digestion of the PCR product with specific endonucleases. The following vascular complications were recorded: stroke, retinopathy, acute thoracic syndrome, and X-ray-documented avascular necrosis. Only one patient was heterozygous for factor V Leiden (1.8% and there was no prothrombin G20210A variant. MTHFR 677TT polymorphism was detected in 1 patient (1.8% and the heterozygous form 677TC was observed in 18 patients (34%, 9 with SS and 9 with SC disease, a prevalence similar to that reported by others. No association was detected between the presence of the MTHFR 677T allele and other genetic modulation factors, such as alpha-thalassemia, ß-globin gene haplotype and fetal hemoglobin. The presence of the MTHFR 677T allele was associated with the occurrence of vascular complications in SCD, although this association was not significant when each complication was considered separately. In conclusion, MTHFR C677T polymorphism might be a risk factor for vascular complications in SCD.

    To determine the frequency of complications/problems occurring with construction of colostomy in infants and children. All the patients admitted in the unit who required colostomy as part of their management were included in the study. The patients who were operated upon previously or operated elsewhere and referred after having colostomy, were excluded. Problems associated with colostomy construction like skin excoriation and chronic blood loss were also recorded. Chi-square test of proportion was used to determine the p-value. There were 121 patients. Most of the patients were operated due to anorectal malformations (n=71) and Hirschsprung's disease (41). Complications/problems related to colostomy occurred in 67.7% patients. The most common problem was skin excoriation. Second in rating was chronic blood loss from stoma. Prolapse of stoma was more common in transverse loop colostomies. Divided colostomies had higher number of complications as compared to loop colostomies, similarly, transverse colostomies had high number of complications but in both the cases difference was not statistically significant. Four (3.3%) patients died. (author)

    Full Text Available Introduction. Localization of ureteric stones and difference in disintegration success are the most important factors in determining the first treatment approach for ureteric stones. Objective. The aim of our study was to evaluate the difference in complication rate between different ureteric stone lithotripsy modalities. Methods. Two hundred sixty patients with ureteric stones were analyzed in a prospective bicentric study that lasted 1 year. The patients were divided into two groups: I - 120 patients who underwent ESWL (extracorporeal shockwave lithotripsy treatment and II - 140 patients who were treated endoscopically with ballistic lithotripsy. Results. Ureteroscopic lithotripsy of all pelvic and iliac stones was significantly more successful comparing to ESWL, while lumbar ureteric stone treatment with ureteroscopic lithotripsy was not significantly more successful than ESWL, except for lumbar stones larger than 100mm2 that were significantly better treated endoscopically. In the I group complications after lithotripsy were recorded in 64 (59.3% and in the II group in 58 (42.0% patients, meaning that complications were statistically significantly more frequent in the I than in the II group. In the II group complications were significantly more often recorded after treatment of proximal comparing to ureteric stones of other localizations, while in the I group complications were significantly more often detected after treatment of impacted stones than in the II group. Conclusion. Being significantly successful comparing to ESWL, ureteric stone treatment with ureteroscopic lithotripsy should be considered as the first therapeutic option for all, especially impacted stones located in the iliac and pelvic ureteric portion. In spite of absent statistical difference in the success rate, ESWL should be chosen as the first treatment option in all cases of lumbar ureteric stones due to lower complication rate except for stones larger than 100mm2 that

    To investigate the perioperative complication rates for paraplegic-quadriplegic patients (PQPs) undergoing percutaneous nephrolithotomy (PCNL) as compared with non-PQPs using a standardized method of complication reporting via the Clavien system. Two hundred thirteen consecutive PCNLs performed by a single surgeon were analyzed. There were 31 and 115 patients separated into PQP and non-PQP groups, respectively. Data collection included demographic and clinical factors, as well as perioperative and delayed complications. Complications were organized by the Clavien grade. All- and initial-procedure complications were analyzed. The rate of adverse events for each Clavien grade was calculated, and statistical comparisons were made. The relationship between PQP and complication severity was investigated using univariate and multivariate analyses. There were 38 and 43 initial-procedure complications in the PQP and non-PQP groups, respectively. The rate of adverse events was higher across the spectrum of Clavien grades for the PQP group, specifically grade 1 (48.4% vs 20.2%; P = .002), grade 2 (22.6% vs 5.3%; P = .004), grade 3b (12.9% vs 2.6%; P = .038), grade 4a (6.5% vs 0%), and grade 4b (9.7% vs 1.8%; P = .066). Approximately 51.6% and 31.5% of PQPs and non-PQPs experienced ≥ 1 complications, respectively (odds ratio = 2.34; P = .05). Multivariate analysis demonstrated paraplegia or quadriplegia status to be an independent risk factor for the development of perioperative complications after adjusting for confounding factors (odds ratio = 2.91; P = .040). PCNL complication rates are higher in PQPs compared with non-PQPs. This study is one of the first in PCNL to use a standardized reporting system to highlight high-risk individuals within the stone population. Copyright © 2015 Elsevier Inc. All rights reserved.

    Many risk factors have been identified in minimally invasive cholecystectomies that lead to higher complications and conversion rates. No study that we encountered looked at nonvisualization of the gallbladder (GB) during surgery as a risk factor. We hypothesized that nonvisualization was associated with an increased risk of complications and could be an early intraoperative identifier of a higher risk procedure. Recognizing this could allow surgeons to be aware of potential risks and to be more likely to convert to open for the safety of the patient. We looked at minimally invasive cholecystectomies performed at our institution from January 2015 through April 2016 and had the performing resident fill out a survey after the surgery. Outcomes were conversion rates, intraoperative complications, and blood loss and were analyzed via Pearson χ 2 test or Mann-Whitney U test. The primary outcome showed a conversion rate of 37% in nonvisualized GBs versus 0% in visualized ( P = .001). Secondary outcomes showed significant differences in GB perforations (74% vs 13%, P = .001), omental vessel bleeding (16% vs. 0%, P = .005), and EBL (46 mL vs 29 mL, P = .001). Intraoperative nonvisualization of the GB after adequate positioning caused significantly increased risk of intraoperative complications and conversion. This knowledge could be useful during intraoperative assessment, to decide whether a case should be continued as a minimally invasive procedure or converted early to help reduce risk to the patient. Further randomized controlled studies should be performed to further demonstrate the value of this assessment.

    Full Text Available Abstract Background Most patients with type 2 diabetes have suboptimal control of their glucose, blood pressure (BP, and lipids – three risk factors for diabetes complications. Although the chronic care model (CCM provides a roadmap for improving these outcomes, developing theoretically sound implementation strategies that will work across diverse primary care settings has been challenging. One explanation for this difficulty may be that most strategies do not account for the complex adaptive system (CAS characteristics of the primary care setting. A CAS is comprised of individuals who can learn, interconnect, self-organize, and interact with their environment in a way that demonstrates non-linear dynamic behavior. One implementation strategy that may be used to leverage these properties is practice facilitation (PF. PF creates time for learning and reflection by members of the team in each clinic, improves their communication, and promotes an individualized approach to implement a strategy to improve patient outcomes. Specific objectives The specific objectives of this protocol are to: evaluate the effectiveness and sustainability of PF to improve risk factor control in patients with type 2 diabetes across a variety of primary care settings; assess the implementation of the CCM in response to the intervention; examine the relationship between communication within the practice team and the implementation of the CCM; and determine the cost of the intervention both from the perspective of the organization conducting the PF intervention and from the perspective of the primary care practice. Intervention The study will be a group randomized trial conducted in 40 primary care clinics. Data will be collected on all clinics, with 60 patients in each clinic, using a multi-method assessment process at baseline, 12, and 24 months. The intervention, PF, will consist of a series of practice improvement team meetings led by trained facilitators over 12

    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.

    Global perturbative QCD analyses, based on large data sets from e-p and hadron collider experiments, provide tight constraints on the parton distribution function (PDF) in the proton. The extension of these analyses to nuclear parton distributions (nPDF) has attracted much interest in recent years. nPDFs are needed as benchmarks for the characterization of hot QCD matter in nucleus-nucleus collisions, and attract further interest since they may show novel signatures of non-linear density-dependent QCD evolution. However, it is not known from first principles whether the factorization of long-range phenomena into process-independent parton distribution, which underlies global PDF extractions for the proton, extends to nuclear effects. As a consequence, assessing the reliability of nPDFs for benchmark calculations goes beyond testing the numerical accuracy of their extraction and requires phenomenological tests of the factorization assumption. Here we argue that a proton-nucleus collision programme at the LHC, including a rapidity scan, would provide a set of measurements allowing for unprecedented tests of the factorization assumption underlying global nPDF fits.

    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.

    The scope of applications of spa-based water procedures have become considerably extended during the recent years; accordingly, the frequency of complications and accidents has increased. The present review considers the possible mechanisms underlying such complications and various factors promoting their development, such as the patients' age and chronic diseases, the use of pharmaceutical products affecting thermoregulation and cardiovascular function. Special attention is given to the influence of alcohol consumption on the frequency of complications, accidents, and sudden death associated with hyperthermal procedures, the possibility of infectious diseases and measures necessary for their prevention.

To evaluate the current local and neurological complication rates of paediatric CA in the setting of a tertiary level children's hospital in the UK. Data from patients who had undergone CA between January 1998 and July 2003 were reviewed. The medical, anaesthetic and nursing records, and angiography reports were reviewed for all identified patients. The following parameters were extracted and entered into a proforma: gender, age, ethnicity, diagnosis, cerebrovascular diagnosis, referral source, date of CA, number of vessels catheterized and local and neurological complications. A total of 176 CA studies were undertaken in 150 patients (median age 7.3 years, range neonate to 19 years; 83 males, 67 females) during the 5.5-year study period. The majority of referrals originated from the neurology (58%) and neurosurgery services (27.8%). No neurological complications or deaths occurred. Local complications occurred in eight children (4.5%). Five children had a groin haematoma and two had bleeding at the puncture site. A single child had a reduced pedal pulse distal to the site of catheterization, but Doppler imaging was normal. CA has a continuing role in the evaluation of cerebrovascular pathologies in children. Neurological complications are rare and local complications are not uncommon (around 5%), but are not usually serious. (orig.)

    Protein energy malnutrition frequently occurs in liver cirrhosis. Hand-grip strength according to Jamar is most reliable to predict protein energy malnutrition. We aimed to determine whether protein energy malnutrition affects complication risk. In 84 cirrhotics, baseline nutritional state was determined and subsequent complications prospectively assessed. Influence of potentially relevant factors including malnutrition (by Jamar hand-grip strength) on complication rates were evaluated with univariate analysis. Effect of malnutrition was subsequently evaluated by multivariate logistic regression with adjustment for possible confounders. Underlying causes of cirrhosis were viral hepatitis in 31%, alcohol in 26%, and other in 43%. Baseline Child-Pugh (CP) class was A, B, or C in 58, 35, and 7%, respectively. Energy and protein intake decreased significantly with increasing CP class, with shift from proteins to carbohydrates. At baseline, according to Jamar hand-grip strength, malnutrition occurred in 67% (n=56). Malnutrition was associated with older age and higher CP class (CP class A 57%, B 79%, C 100%) but not with underlying disease or comorbidity. Complications occurred in 18 and 48% in well-nourished and malnourished patients, respectively, (P=0.007) during 13 ± 6 months follow-up. In multivariate analysis, malnutrition was an independent predictor of complications, after correcting for comorbidity, age, and CP score (adjusted odds ratio 4.230; 95% confidence interval 1.090-16.422; P=0.037). In univariate analysis, mortality (4 vs. 18%; P=0.1) tended to be worse in malnourished patients, but this trend was lost in multivariate analysis. Malnutrition is an independent predictor of complications in cirrhosis.

    Abstract Background Most patients with type 2 diabetes have suboptimal control of their glucose, blood pressure (BP), and lipids – three risk factors for diabetes complications. Although the chronic care model (CCM) provides a roadmap for improving these outcomes, developing theoretically sound implementation strategies that will work across diverse primary care settings has been challenging. One explanation for this difficulty may be that most strategies do not account for the complex adapti...

    A best evidence topic was written according to a structured protocol. The question addressed was: in patients undergoing oesophagectomy for oesophageal malignancy, is low serum albumin associated with postoperative complications? Altogether, 87 papers were found using the reported search, of which 16 demonstrated the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. This paper includes 2 level 2 papers, 12 level 3 papers and 2 level 4 papers. All the papers compared either all or some of the following postoperative complications: mortality, morbidity, anastomotic leak, respiratory and non-respiratory complications, and length of hospital stay. Eleven of the 16 papers found an association between low serum albumin and postoperative complications. Of these, one study showed that low serum albumin combined with low fibrinogen levels (FA score) was predictive of postoperative recurrence of oesophageal cancer. Another study showed that when combined with white cell count and C-reactive protein (CRP, NUn score), serum albumin had a high diagnostic accuracy for major complications after postoperative day 3. The largest study compared the in-hospital mortality in 7227 patients who underwent oesophageal surgery for malignancy. The percentage of in-hospital mortality was associated with low serum albumin (35.0 g/l, 21.0 vs 11.3%, P papers found no significant association between low serum albumin and postoperative complications. Of these papers, one showed that low serum albumin was not an independent risk factor, while four others found no association between low serum albumin with respiratory complications, anastomotic leak and postoperative mortality. Instead, these studies found other factors responsible for postoperative complications such as: CRP, smoking, disease duration, malnutrition and low T-cell levels. Taken together

    Twenty-seven children with acute leukemia were studied in order to detect the subsequent neurologic complications due to chemotherapy and radiation therapy. Twenty-four patients with ALL received central nervous system prophylaxis including cranial irradiation. The methods of evaluation consisted of electroencephalogram (EEG), computed tomography of the head (CT scan), soft neurological sign, intelligence quotient (IQ) and Bender Gestalt test. The patients with relapse showed severe abnormalities in various kinds of examinations. Younger children at diagnosis were associated with a higher abnormality rate of soft neurological signs and Bender Gestalt test. Factors which were found to be closely associated with a lower IQ score included younger children at diagnosis and longer duration of remission time. These results indicate the need for caution for the dosage of cranial irradiation for younger patients in CNS prophylaxis, and improvement of a lower IQ score in long-term survivors requires further investigation as to the appropriate intellectual environment for their development after remission.

    To balance the cardiovascular benefits from low-dose aspirin against the gastrointestinal harm caused, studies have considered the coronary heart disease risk for each individual but not their gastrointestinal risk profile. We characterized the gastrointestinal risk profile of low-dose aspirin users in real clinical practice, and estimated the excess risk of upper gastrointestinal complications attributable to aspirin among patients with different gastrointestinal risk profiles. To characterize aspirin users in terms of major gastrointestinal risk factors (i.e., advanced age, male sex, prior ulcer history and use of non-steroidal anti-inflammatory drugs), we used The General Practice Research Database in the United Kingdom and the Base de Datos para la Investigación Farmacoepidemiológica en Atención Primaria in Spain. To estimate the baseline risk of upper gastrointestinal complications according to major gastrointestinal risk factors and the excess risk attributable to aspirin within levels of these factors, we used previously published meta-analyses on both absolute and relative risks of upper gastrointestinal complications. Over 60% of aspirin users are above 60 years of age, 4 to 6% have a recent history of peptic ulcers and over 13% use other non-steroidal anti-inflammatory drugs. The estimated average excess risk of upper gastrointestinal complications attributable to aspirin is around 5 extra cases per 1,000 aspirin users per year. However, the excess risk varies in parallel to the underlying gastrointestinal risk and might be above 10 extra cases per 1,000 person-years in over 10% of aspirin users. In addition to the cardiovascular risk, the underlying gastrointestinal risk factors have to be considered when balancing harms and benefits of aspirin use for an individual patient. The gastrointestinal harms may offset the cardiovascular benefits in certain groups of patients where the gastrointestinal risk is high and the cardiovascular risk is low.

    PurposeTo assess the scope and determining risk factors related to the development of pneumothorax throughout CT-guided biopsy of pulmonary lesions in coaxial and non-coaxial techniques and the outcome of its management.Materials and MethodsThe study included CT-guided percutaneous lung biopsies in 650 consecutive patients (407 males, 243 females; mean age 54.6 years, SD 5.2) from November 2008 to June 2013 in a retrospective design. Patients were classified according to lung biopsy technique into coaxial group (318 lesions) and non-coaxial group (332 lesions). Exclusion criteria for biopsy were lesions <5 mm in diameter, uncorrectable coagulopathy, positive-pressure ventilation, severe respiratory compromise, pulmonary arterial hypertension, or refusal of the procedure. Risk factors related to the occurrence of pneumothorax were classified into: (a) Technical risk factors, (b) patient-related risk factors, and (c) lesion-associated risk factors. Radiological assessments were performed by two radiologists in consensus. Mann–Whitney U test and Fisher’s exact tests were used for statistical analysis. p values <0.05 were considered statistically significant.ResultsThe incidence of pneumothorax complicating CT-guided lung biopsy was less in the non-coaxial group (23.2 %, 77 out of 332) than the coaxial group (27 %, 86 out of 318). However, the difference in incidence between both groups was statistically insignificant (p = 0.14). Significant risk factors for the development of pneumothorax in both groups were emphysema (p < 0.001 in both groups), traversing a fissure with the biopsy needle (p value 0.005 in non-coaxial group and 0.001 in coaxial group), small lesion, less than 2 cm in diameter (p value of 0.02 in both groups), location of the lesion in the basal or mid sections of the lung (p = 0.003 and <0.001 in non-coaxial and coaxial groups, respectively), and increased needle track path within the lung tissue of more than 2.5 cm (p = 0.01 in both

    The significance of sarcopenia after colorectal cancer (CRC) resection has only been discussed with relatively small samples or short follow-up periods. This study aimed to clarify the clinical significance of sarcopenia in a large-sample study. We retrospectively analyzed the relationship between sarcopenia and clinical factors, surgical outcomes, and the survival in 494 patients who underwent CRC surgery between 2004 and 2013. Sarcopenia was defined based on the sex-specific skeletal muscle mass index measured by preoperative computed tomography. Sarcopenia was associated with sex (higher rate of male, P Sarcopenia was associated with higher incidence of all postoperative complications (P = 0.02), especially for patients with Clavien-Dindo classification grade ≥2 (CDC; P = 0.0007). Postoperative hospital stays were significantly longer for sarcopenic patients than for non-sarcopenic patients (P = 0.02). In a multivariate analysis, sarcopenia was an independent predictor for postoperative complications (P = 0.01, odds ratio 1.82, 95% confidence interval 1.13-3.00). Among postoperative complications (CDC grade ≥2), sarcopenia was correlated with non-surgical-site infections (P = 0.03). Sarcopenia was not correlated with the overall or recurrence-free survival. Sarcopenia was an independent predictive factor for postoperative complications after CRC surgery.

    Local control is the important prognostic factor in cancer treatment because local control decrease the relative risk of metastatic spread and increase distant metastasis free survival. IORT is the modality which could increase local control without increasing complication, combined with curative operation. Even though we could achieve significant decreased local failure by IORT and curative resection, it should not be committed as a main treatment modality without proving acceptable complications. Therapeutic Radiology Department of Yeungnam University Medical Center have tried 58 IORT from June 15, 1988, and performed 53 IORT in patients with gastric cancer. No local failure has been report? by regular follow up so far. Nine cases(17%) of treatment related complication were reported including intestinal obstruction, hemorrhage, sepsis, and bone marrow depression. These complications could be comparable to Jo 25.2% (chemotherapy + operation), Kim 18% (chemotherapy only in inoperable patients), because our treatment regimen is consisted of IORT (1500 cGy), external irradiation(--4500 cGy) and extensive chemotherapy (FAM, 5FU+MMC, BACOP). Our data encouraged us to re-inforce further IORT in stomach cancer treatment

    Dose-response isoeffect equations have been determined for hypothalamic pituitary insufficiency following cranial irradiation. Of particular importance is the occurrence of complications at doses substantially less than those commonly used for the treatment of central nervous system tumors. Such complications may be severe and potentially life threatening. These complications occur when a small midline 'target' volume containing the pituitary gland, infundibulum and adjacent inferior hypothalamic structures is irradiated. Direct pituitary irradiation is unlikely to be a factor, at least in some cases. The possible role of incidental hypothalamic irradiation in the control of acromegaly and pituitary dependent Cushing's syndrome is discussed.

    This study aims to evaluate the effect of sleep apnea (SA) on perioperative complications after total joint arthroplasty (TJA) and whether the type of anesthesia influences these complications. Using the ninth and tenth revisions of the International Classification of Diseases, coding systems, we queried our institutional TJA database from January 2005 to June 2016 to identify patients with SA who underwent TJA. These patients were matched in a 1:3 ratio based on age, gender, type of surgery, and comorbidities to patients who underwent TJA but were not coded for SA. Perioperative complications were identified using the same coding systems. Multivariate analysis was used to test if SA is an independent predictor of perioperative complications and if type of anesthesia can affect these complications. A total of 1246 patients with SA were matched to 3738 patients without SA. Pulmonary complications occurred more frequently in patients with SA (1.7% vs 0.6%; P system complications and mortality (odds ratio = 15.88; 95% confidence interval, 3.93-64.07; P gastrointestinal complications, acute anemia, and mortality were lower in SA patients when regional anesthesia was used (P < .05). SA increases risk of postoperative pulmonary complications. The use of regional anesthesia may reduce risk of pulmonary complications and mortality in SA patients undergoing TJA.

    Currently, a lot of space and time is devoted to the therapy of oncologic diseases itself. To reach the good therapy results, complex care of the oncologic patient is needed. Management of complications linked with the disease itself and management of complications emerged after administration of chemotherapy, radiotherapy or targeted therapy, plays a significant role. In addition to infectious, hematological, neurological, cardiac or other complications, metabolic complications are relatively extensive and serious. One of the most frequent metabolic complications in oncology is tumor lysis syndrome, hyperuricemia, hypercalcaemia and syndrome of inappropriate secretion of antidiuretic hormone. (author)

    Early surgical education is required for neurosurgical residents to learn many surgical procedures. However, the participation of less experienced residents may increase perioperative complication rates. Perioperative complication studies in the field of neurosurgery are being increasingly published; however, studies have not yet focused on cervical laminoplasty. The study population included 193 consecutive patients who underwent cervical laminoplasty in Tokyo Metropolitan Neurological Hospital between 2008 and 2014. Patient and surgeon background factors, as well as perioperative complication rates were retrospectively compared between resident and board-certified spine neurosurgeon groups. Deteriorated or newly developed neurological deficits and surgical site complications within 30days of cervical laminoplasty were defined as perioperative complications. Out of 193 patients, 123 (64%) were operated on by residents as the first operator and 70 (36%) by board-certified spine neurosurgeons. No significant differences were observed in patient and surgeon factors between the two groups, except for hyperlipidemia (13 vs 17, p=0.02). Furthermore, no significant differences were noted in perioperative complication rates between the two groups (7 [5.7%] vs 4 [5.7%], p=1). Cervical laminoplasty performed in a standardized manner by residents who received their surgical training in our hospital did not increase perioperative complication rates, and ensured the safety of patients.

    Full Text Available Background: Different complications may occur at laparoscopic port sites. The incidence of these varies with the size of the ports and the types of procedure performed through them. Objectives: The aim was to observe the rate and types of complications attending laparoscopic port wounds and to identify risk factors for their occurrence. Patients and Methods: This is a prospective descriptive study of all patients who had laparoscopic operations in one general surgery unit of a University Teaching Hospital in Nigeria between January 2009 and December 2012. Results: A total of 236 (155 female and 81 male patients were included. The laparoscopic procedures include 63 cholecystectomies, 49 appendectomies, 62 diagnostic, biopsy and staging procedures, 22 adhesiolyses, six colonic surgeries, eight hernia repairs and 22 others. Port site complications occurred in 18 (2.8% ports on 16 (6.8% patients including port site infections in 12 (5.1% and hypertrophic scars in 4 (1.7% patients, while one patient each had port site bleeding and port site metastasis. Nine of 11 infections were superficial, while eight involved the umbilical port wound. Conclusion: Port site complications are few following laparoscopic surgeries in our setting. We advocate increased adoption of laparoscopic surgeries in Nigeria to reduce wound complications that commonly follow conventional open surgeries.

    The 4th National Audit Project of the Royal College of Anaesthetists and the Difficult Airway Society (NAP4) analysed reports of serious events arising from airway management during anaesthesia, intensive care and the emergency department. We conducted supplementary telephone interviews with 12 anaesthetists who had reported to NAP4, aiming to identify causal factors using a method based on the Human Factors Investigation Tool (HFIT). We identified contributing human factors in all cases (median [range] 4.5 [1-10] per case). The most frequent related to: situation awareness (failures to anticipate, wrong decision) (nine cases); job factors (e.g. task difficulty; staffing, time pressure) (eight cases); and person factors (e.g. tiredness, hunger, stress) (six cases). Protective factors, such as teamwork and communication, were also revealed. The post-report HFIT interview method identified relevant human factors and this approach merits further testing as part of the investigation of anaesthetic incidents.

    The morbidity and mortality of preterm infants are impacted by their ability to maintain physiologic homeostasis using metabolic, endocrine, and immunologic mechanisms independent of the mother's placenta. Exploring McEwen's allostatic load model in preterm infants provides a new way to understand the altered physiologic processes associated with frequently occurring complications of prematurity such as bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, and retinopathy of prematurity. The purpose of this article is to present a new model to enhance understanding of the altered physiologic processes associated with complications of prematurity. The model of allostatic load and complications of prematurity was derived to explore the relationship between general stress of prematurity and complications of prematurity. The proposed model uses the concepts of general stress of prematurity, allostasis, physiologic response patterns (adaptive-maladaptive), allostatic load, and complications of prematurity. These concepts are defined and theoretical relationships in the proposed model are interpreted using the four maladaptive response patterns of repeated hits, lack of adaptation, prolonged response, and inadequate response. Empirical evidence for cortisol, inflammation, and oxidative stress responses are used to support the theoretical relationships. The proposed model provides a new way of thinking about physiologic dysregulation in preterm infants. The ability to describe and understand complex physiologic mechanisms involved in complications of prematurity is essential for research. Advancing the knowledge of complications of prematurity will advance clinical practice and research and lead to testing of interventions to reduce negative outcomes in preterm infants.

  20. Automatic Bayes Factors for Testing Equality- and Inequality-Constrained Hypotheses on Variances.

    2018-05-03

    In comparing characteristics of independent populations, researchers frequently expect a certain structure of the population variances. These expectations can be formulated as hypotheses with equality and/or inequality constraints on the variances. In this article, we consider the Bayes factor for testing such (in)equality-constrained hypotheses on variances. Application of Bayes factors requires specification of a prior under every hypothesis to be tested. However, specifying subjective priors for variances based on prior information is a difficult task. We therefore consider so-called automatic or default Bayes factors. These methods avoid the need for the user to specify priors by using information from the sample data. We present three automatic Bayes factors for testing variances. The first is a Bayes factor with equal priors on all variances, where the priors are specified automatically using a small share of the information in the sample data. The second is the fractional Bayes factor, where a fraction of the likelihood is used for automatic prior specification. The third is an adjustment of the fractional Bayes factor such that the parsimony of inequality-constrained hypotheses is properly taken into account. The Bayes factors are evaluated by investigating different properties such as information consistency and large sample consistency. Based on this evaluation, it is concluded that the adjusted fractional Bayes factor is generally recommendable for testing equality- and inequality-constrained hypotheses on variances.

  1. The role of the internal medicine specialist in the management of infective complications in general surgical wards

    2013-05-01

    Full Text Available BACKGROUND Internal medicine specialists are often asked to evaluate a patient before surgery. Perioperative risk evaluation for elderly patients is important, because complications increase with age. The increasing age of the general population increases the probabilities of surgery in the older patients. The manifestation of a surgical problem, is more likely to be severe and complicated in the elderly patients. In fact, emergency surgery treatment occurs more frequently in the elderly (e.g., it is much more common to see intestinal obstruction complicating colorectal cancer in the elderly compared with a younger population. Old age is an independent factor for long hospital stay after surgery. The role of the preoperative medical consultant is to identify and evaluate a patient’s current medical status and provide a clinical risk profile, in order to decide whether further tests are indicated prior to surgery, and to optimise the patient’s medical condition in the attempt of reducing the risk of complications. The medical consultant must know which medical condition could eventually influence the surgery, achieve a good contact and communication between the medical and surgical team, in order to obtain the best management planning. AIM OF THE STUDY This paper focuses on the rational use of antibiotic prophylaxis and on the treatment of the complications of post-surgery infections (e.g., pulmonary complication, peritonitis, intra-abdominal infection. Specific aspects of pre-operative risk evaluation and peri and post-operative management are discussed. CONCLUSIONS The internal medicin specialist in collaboration with the surgical team is necessary in the peri and post-surgery management.

  2. Helicobacter pylori eradication in complicated peptic ulcer: Beneficial in most?

    Full Text Available Helicobacter pylori eradication therapy has a role in minimizing the complications of peptic ulcer disease, namely, bleeding, perforation, and obstruction. However, the precise role of H. pylori eradication therapy in the complicated ulcers remains inconclusive, especially in perforation and gastric outlet obstruction. The prevalence of H. pylori in peptic ulcer bleeding patients has been widely underestimated owing to the differences in diagnostic tests and patient characteristics, and hence, it is recommended that an initial negative test should be followed up by a delayed repeat testing to rule out false negativity. It is well established now that eradication of H. pylori in patients with bleeding ulcers reduces rebleeding and ulcer recurrence. Multiple studies have attributed high recurrence rates of duodenal ulcer following simple closure to a high prevalence of H. pylori infection. Eradication therapy decreases the recurrence rate of perforated ulcers, thus justifying the role of H. pylori eradication therapy following the primary surgical management of perforated ulcers. The role of H. pylori in duodenal ulcer with gastric outlet obstruction is yet to be evaluated clearly. There are some reports of resolution of gastric outlet obstruction following therapy for H. pylori, obviating the need for surgery. Clarithromycin-containing regimens are recommended as first-line in areas of low resistance, whereas bismuth-containing quadruple therapy is the first-line empirical treatment in areas of high clarithromycin resistance. Treatment of H. pylori is beneficial in most of the patients with complicated peptic ulcer disease, especially in reducing recurrence of ulcer with or without complications.

  3. Complications of Circumcision

    Full Text Available In the United States, circumcision is a commonly performed procedure. It is a relatively safe procedure with a low overall complication rate. Most complications are minor and can be managed easily. Though uncommon, complications of circumcision do represent a significant percentage of cases seen by pediatric urologists. Often they require surgical correction that results in a significant cost to the health care system. Severe complications are quite rare, but death has been reported as a result in some cases. A thorough and complete preoperative evaluation, focusing on bleeding history and birth history, is imperative. Proper selection of patients based on age and anatomic considerations as well as proper sterile surgical technique are critical to prevent future circumcision-related adverse events.

  4. Oral complications of radiation therapy

    Approximately 24,000 patients are diagnosed each year with malignant tumors of the head and neck. Many of these patients will be treated with radiotherapy, surgery, or chemotherapy, either singly or in combination. Certain predictable sequelae of radiotherapy exist that may be considered consequences of treatment rather than complications; these may be unavoidable consequences of curative radiotherapy to the head and neck. There are, however, additional problems that occur as a result of radiotherapy that are preventable in both incidence and severity, and are therefore avoidable complications. Cell kinetic factors, radiosensitivity of normal tissues, radiotherapeutic doses necessary for tumor control, and the complex anatomy of the maxillofacial region often predispose patients serious treatment morbidity. The potential for pain, infection, and long-term functional disability with decreased quality of life dictate conscientious management before, during, and after radiotherapy. This chapter discusses common problems that can arise, as well as current methods utilized both to improve patient tolerance to treatment and to decrease the risk of preventable and potentially dose-limiting morbidity

    The effects of chronic corticosteroid therapy on complications, readmission, and reoperation after posterior lumbar fusion (PLF) remain underinvestigated, and were examined to determine differences in outcomes. We analyzed patients undergoing PLF between 2006 and 2013 using the National Surgery Quality Improvement Program database (NSQIP). Patients taking steroids for a chronic condition were compared with those not taking steroids. Multivariable regression identified factors independently associated with complications, readmission, and reoperation. A risk score was calculated for predicting complications. A total of 8492 patients were identified, of whom 353 used steroids. The patients using steroids were older (mean age, 65.4 years vs. 61.0 years; P steroid group. On multivariable regression, steroids were independently associated with overall complications (odds ratio [OR], 1.38; P = 0.044) and infectious complications (OR, 1.65; P < 0.001), but not with medical complications, readmission, or reoperation. Patients with higher risk scores had higher complication rates. The use of corticosteroid therapy is associated with a moderately increased risk of overall complications, but no association was found with readmission or reoperation. Copyright © 2017.

    Children with certain risk factors, such as comorbidities or severe obstructive sleep apnea syndrome (OSAS) are known to require extended postoperative monitoring after adenotonsillectomy. However, there are no recommendations available for diode-laser-assisted tonsillotomy. A retrospective chart review of 96 children who underwent diode-laser-assisted tonsillotomy (07/2011-06/2013) was performed. Data for general and sleep apnea history, power of the applied diode-laser (λ = 940 nm), anesthesia parameters, the presence of postoperative respiratory complications and postoperative healing were evaluated. After initially uncomplicated diode-laser-assisted tonsillotomy, an adjustment of post-anesthesia care was necessary in 16 of 96 patients due to respiratory failure. Respiratory complications were more frequent in younger children (3.1 vs. 4.0 years, p = 0.049, 95 % CI -1.7952 to -0.0048) and in children who suffered from nocturnal apneas (OR = 5.00, p diode-laser power higher than 13 W could be identified as a risk factor for the occurrence of a postoperative oropharyngeal edema (OR = 3.45, p diode-laser-assisted tonsillotomy. We recommend a reduced diode-laser power (<13 W) to reduce oropharyngeal edema.

    Full Text Available Background: Tissue expansion is a common reconstructive surgery especially in burned patients. This study has been designed to evaluate the rate of complications of this method in Hazrat Fatima Hospital between 1389-1391. Materials & Methods: In this cross sectional and retrospective study, 150 patients' records have been studied between 1389-1391 years, frequency rate and types of complications related to tissue expander have been surveyed in these patients. Results: Complications have been observed in about 7% of the patients included in this study. Exposure of tissue expander was the most common complication (81.8%. Other complications which are resulted from this issue are capsular contracture and infection. Age was the only factor which had significant relation with increasing complication among the other surveyed factors including age, sex, indication of operation, wound location and duration of anaesthesia.(p=0.033 Conclusion: The incidence of complication in patients that required tissue expander was not high and it was less than 10%. It should be noted that patient selection should be carefully in paediatric group and also strict observance of surgical principles is necessary to avoid complication.

    From an analysis of the data reported in the literature it is clear that pregnancy is a predisposing factor for urinary tract infection and that pregnant women with this pathology are exposed to dangerous risks which may influence maternal wellbeing and fetal prognosis. Authors do not concur on the specific risks to the mother and fetus, one reason being that the statistics reported to date reveal discrepancies relating to the presence of disorders prior to pregnancy and the environmental, working and socio-hygienic conditions of the populations studied. The apparently paradoxical finding of a higher incidence of perinatal problems in pregnant women with asymptomatic bacteriuria compared to manifest forms can be attributed to the fact that the latter are treated with adequate therapies whereas asymptomatic bacteriuria, which is difficult to diagnose, may persist throughout pregnancy. This underlines the importance of early diagnosis using a protocol which entails the execution of serial urine tests and urine cultures and adequate treatment of all cases of asymptomatic bacteriuria in order to reduce the incidence of urinary tract infections and materno-fetal complications. Non-treated asymptomatic bacteriuria in fact represents a considerable risk factor since it may lead to the onset of acute pyelonephritis in approximately 5% of pregnant women and may increase the risk of fetal mortality.

    Objectives This study aimed to evaluate cardiovascular complications among patients who abuse amphetamines. Methods This cross-sectional study took place between April 2014 and April 2015 among 3,870 patients referred to the Toxicology Emergency Department of Baharlou Hospital, Tehran University of Medical Sciences, Tehran, Iran. Those with clinical signs of drug abuse and positive urine screening tests were included in the study, while cases of chronic abuse were excluded. Cardiac complications were evaluated via electrocardiography (ECG) and transthoracic echocardiography. Results A total of 230 patients (5.9%) had a history of acute amphetamine abuse and positive urine tests. Of these, 32 patients (13.9%) were <20 years old and 196 (85.2%) were male. In total, 119 (51.7%) used amphetamine and methamphetamine compounds while 111 (48.3%) used amphetamines with morphine or benzodiazepines. The most common ECG finding was sinus tachycardia (43.0%), followed by sinus tachycardia plus a prolonged QT interval (34.3%). Mean creatine kinase-MB and troponin I levels were 35.9 ± 4.3 U/mL and 0.6 ± 0.2 ng/mL, respectively. A total of 60 patients (26.1%) were admitted to the Intensive Care Unit. The majority (83.3%) of these patients had normal echocardiography results. The mean aortic root diameter (ARD) was 27.2 ± 2.8 mm. Abnormalities related to the ARD were found in 10 patients (16.7%), three of whom subsequently died. Conclusion According to these findings, cardiac complications were common among Iranian patients who abuse amphetamines, although the majority of patients had normal echocardiography and ECG findings.

    Postoperative surgical complications arising from ventral hernia repair have been assessed by a variety of outcome measures. The objective of this study was to correlate the Clavien Dindo Classification (CDC) graded complications with the 30-day readmission rate as early outcome measures in ventral hernia repair. Secondarily, we wanted to investigate whether the risk factors for Clavien Dindo class ≥1 and 30-day readmission were comparable. Single-centre retrospective study including all patients (≥18 years) who underwent ventral hernia repair between January 1, 2009 and September 1, 2014 at Zealand University Hospital. Data were obtained from hospital files and the Danish National Patient Registry. A 100% follow-up was obtained. In total, the study included 700 patients (261 patients with incisional hernia repair and 439 patients with umbilical or epigastric hernia repair). There was a significant association between a complication graded by the CDC ≥1 and 30-day readmission for both incisional and umbilical/epigastric hernia repair (p readmission. Recurrent (vs. primary) hernia repair was an independent risk factors for both CDC ≥1 and 30-day readmission in umbilical/epigastric hernia repair. Furthermore, hernia size 2-7 cm (vs. >2 cm) was a risk factor for CDC ≥1 but not for 30-day readmission in umbilical/epigastric hernia repair. Reports on 30-day readmission can be used as a general outcome measure in ventral hernia repair, however CDC provides a more precise and detailed registration of postoperative complications.

There is no clearly defined medical literature on complication in lumbar spine surgery. Purpose of the study is to retrospectively evaluate intraoperative and perioperative complications who underwent various lumbar surgical procedures and to study the possible predisposing role of advanced age in increasing this rate. Materials and Methods: From 2007 to 2011 the number and type of complications were recorded and both univariate, (considering the patients′ age and a multivariate statistical analysis was conducted in order to establish a possible predisposing role. 133 were lumbar disc hernia treated with microdiscetomy, 88 were lumbar stenosis, treated in 36 cases with only decompression, 52 with decompression and instrumentation with a maximum of 2 levels. 26 patients showed a lumbar fracture treated with percutaneous or open screw fixation. 12 showed a scoliotic or kyphotic deformity treated with decompression, fusion and osteotomies with a maximum of 7.3 levels of fusion (range 5-14. 70 were spondylolisthesis treated with 1 or more level of fusion. In 34 cases a fusion till S1 was performed. Results: Of the 338 patients who underwent surgery, 55 showed one or more complications. Type of surgical treatment ( P = 0.004, open surgical approach (open P = 0.001 and operative time ( P = 0.001 increased the relative risk (RR of complication occurrence of 2.3, 3.8 and 5.1 respectively. Major complications are more often seen in complex surgical treatment for severe deformities, in revision surgery and in anterior approaches with an occurrence of 58.3%. Age greater than 65 years, despite an increased RR of perioperative complications (1.5, does not represent a predisposing risk factor to complications ( P = 0.006. Conclusion: Surgical decision-making and exclusion of patients is not justified only

    Conclusion: The outcome of CAVB complicated with myocarditis is variable. Most of our patients resumed normal heart function. The incidence of persistent CAVB was 22%. VT is a common and serious complication, but it can be effectively treated medically. Persistent low cardiac output after pacemaker implantation and late onset VT should be considered as risk factors of mortality.

    (1) To identify tracheostomy complications in institutionalized children with chronic tracheostomy. (2) To determine factors that predispose to development of tracheostomy complications in institutionalized children with chronic tracheostomy. Case series with chart review over 10 years. Tertiary children's hospital. Children were included if they underwent tracheostomy before 21 years of age and resided at a pediatric nursing facility. Most children were ventilator dependent and had severe comorbid medical conditions, including developmental delay and cerebral palsy. The number of tracheostomy complications and unplanned hospital admissions were recorded. Interventions for tracheostomy complications were also reviewed. Thirty-two institutionalized children with chronic tracheostomy were included. The mean age at time of tracheostomy was 5.4 years, with a mean duration of institutionalization of 9.1 years. Twenty-seven children (84%) experienced tracheostomy complications. The total number of complications was 79. The most common tracheostomy complications identified were peristomal granulation (n = 13) and suprastomal granulation (n = 12). Age at time of tracheostomy, duration of institutionalization, and ventilator dependence did not predict the likelihood of developing a complication. Of 32 patients, 20 were evaluated in the emergency room during the study, and there were 48 unplanned admissions for tracheostomy-related complications during the study. Forty-five urgent direct laryngoscopy and bronchoscopy procedures were performed in a total of 20 children with tracheostomy complications. Tracheostomy complications are common in institutionalized children with chronic tracheostomy and are challenging to manage. Further research is necessary to determine novel ways to reduce tracheostomy complications in this population. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Our aim was to evaluate the influence of the localization of right posterior bile duct anatomy relative to portal vein of the donors on posttransplant bile duct complications. We retrospectively investigated 141 patients who had undergone living donor liver transplant using right hemiliver grafts. The patients were classified based on the pattern of the right posterior bile duct and divided into infraportal and supraportal types. Clinical donor and recipient risk factors and surgical outcomes were compared for their relationship with biliary complications using logistic regression analyses. The 2 groups were similar according to demographic and clinical features. The biliary complication rate was 23.7% (9/38) in the infraportal group and 47.4% (37/78) in the supraportal group (P = .014). An analysis of risk factors for the development of anastomotic bile leak using logistic regression showed that a supraportal right posterior bile duct anatomy was a statistically significant positive predictor, with odds ratio of 18.905 (P = .012; confidence interval, 1.922-185.967). The distance of the right posterior bile duct from confluence was significantly lower in patients with biliary complications than in those without (mean of 7.66 vs 0.40 mm; P = .044). According to receiver operating characteristic analyses, the cut-off point for the length of right bile duct to right posterior bile duct from the hepatic confluence was 9.5 mm regarding presence of complications. Factors influencing bile duct anastomosis leakage were supraportal-type donor bile duct anatomy and length of the right main bile duct from biliary confluence. Hepatic arterial complications were similarly a risk factor for biliary strictures. Because of the multiple factors leading to complications in living donor liver transplant, it is challenging to group these patients by operative risk; however, establishing risk models may facilitate the prediction of complications.

    Intra-abdominal testes can be treated with several surgical procedures. We evaluated factors influencing the outcome of orchiopexy for intra-abdominal testis. We retrospectively reviewed 156 consecutive orchiopexies performed for intra-abdominal testis, defined as a nonpalpable testis on examination and located in the abdomen at surgery. All surgical approaches were included in the study. Primary outcome was the overall success rate and secondary outcomes were success based on surgical approach, age and a patent processus vaginalis. Success was considered a testis with normal texture and size compared to the contralateral testis at followup. Multivariate analysis was performed to determine factors predictive of success. The overall success rate of all orchiopexies was 79.5%. Median patient age at orchiopexy was 12 months and mean followup was 16 months. Of the patients 117 had a patent processus vaginalis at surgery. One-stage abdominal orchiopexy was performed in 92 testes with 89.1% success. Of these cases 32 were performed laparoscopically with 96.9% success. One-stage Fowler-Stephens orchiopexy was performed in 27 testes and 2-stage Fowler-Stephens orchiopexy was performed in 37 with success in 63.0% and 67.6%, respectively. Multivariate analysis revealed that 1-stage orchiopexy without vessel division had more successful outcomes than 1 and 2-stage Fowler-Stephens orchiopexy (OR 0.24, p = 0.007 and 0.29, p = 0.19, respectively). Neither age at surgery nor an open internal ring was significant (p = 0.49 and 0.12, respectively). The overall success of orchiopexy for intra-abdominal testis is 79.5%. While patient selection remains a critical factor, 1-stage orchiopexy without vessel division was significantly more successful and a laparoscopic approach was associated with the fewest failures for intra-abdominal testes.

    In spite of many advances in medicine, anesthetic technique and surgical managements, pulmonary problems are the most frequent postoperative complications, particularly after abdominal surgery. As postoperative pulmonary complications, atelectasis, pleural effusion, pneumonia, chronic bronchitis and lung abscess can be occurred. This study include evaluation of chest films of 2006 patients (927 male, 1079 female), who had been operated abdominal surgery from Jan. 1979 to June, 1980 in the Hanyang university hospital. The results were as follows: 1. 70 cases out of total 2006 cases (3.5%) developed postoperative chest complications, 51 cases (5.5%) in male, 19 cases (1.8%) in female. 2. The complication rate was increased according to the increase of age. The incidence of the postoperative complications over 40 years of age was higher than the overall average complications rate. 3. The most common postoperative pulmonary complication was pleural effusion, next pneumonia, atelectasis and pulmonary edema respectively. 4. The complication rate of the group of upper abdominal surgery is much higher than the group of lower abdominal surgery. 5. Complication rate was increased according to increase of the duration of operation. 6. There were significant correlations between the operation site and side of the complicated hemithorax

    Markers that predict the occurrence of a complicated disease behavior in patients with Crohn's disease (CD) can permit a more aggressive therapeutic regimen for patients at risk. The aim of this cohort study was to test the blood levels of hemoglobin (Hgb) and hematocrit (Hct) for the prediction of complicated CD behavior and CD related surgery in an adult patient population. Blood samples of 62 CD patients of the German Inflammatory Bowel Disease-network "Kompetenznetz CED" were tested for the levels of Hgb and Hct prior to the occurrence of complicated disease behavior or CD related surgery. The relation of these markers and clinical events was studied using Kaplan-Meier survival analysis and adjusted COX-proportional hazard regression models. The median follow-up time was 55.8 months. Of the 62 CD patients without any previous complication or surgery 34% developed a complication and/or underwent CD related surgery. Low Hgb or Hct levels were independent predictors of a shorter time to occurrence of the first complication or CD related surgery. This was true for early as well as late occurring complications. Stable low Hgb or Hct during serial follow-up measurements had a higher frequency of complications compared to patients with a stable normal Hgb or Hct, respectively. Determination of Hgb or Hct in complication and surgery naïve CD patients might serve as an additional tool for the prediction of complicated disease behavior.

Methods: A 21 years retrospective study was conducted of the clinical charts of patients whose reason for consultation was axial lumbar pain from degenerative disc disease, and who underwent surgery using non-endoscopic discectomy and nucleoplasty (NEDN. Two groups were established; the first, NEDN with laser, and second, NEDN with radiofrequency. The number and types of complications reported in the case-series were counted, and their statistical differences determined. Results: The inclusion criteria were fulfilled by 643 of the medical charts. 26 complications were reported, the most common being radiculitis (n=12. Statistically significant differences were found between the complications occurring in the two groups (p=0.01. Conclusion: The number of complications showed statistically significant difference. The severity of the complications and adverse outcomes provide an argument for choosing one technology over the other. Training and the learning curve stage are important factors to be taken into account, to avoid complications.

    In recent years, a plethora of novel therapeutic approaches to fight signs of aging and to influence external body appearance have become available in aesthetic dermatology. Extensive research in this field has led to advanced understanding of the anatomy and physiology of the aging face. To successfully address the complex age-related alterations anti-aging treatment nowadays calls for a multi-faceted approach. Most frequently utilized aesthetic procedures include the use of botulinum toxin, a variety of filling substances, microneedling (collagen induction therapy), chemical peeling, lasers, radiofrequency, thread facelift and injectional lipolysis with phosphatidylcholine/deoxycholate among others. Unfortunately, many clinicians still lack in-depth understanding of potential complications, risk factors and side effects associated with minimal-invasive procedures. The following review aims to give a broad overview of nowadays most frequently used approaches in the dermato-aesthetic field and their related complications. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

    Mandible angle fractures can be repaired in a variety of ways, with no consensus on the outcomes of complications and reoperation rates. To analyze patient, injury, and surgical factors, including approach to the angle and plating technique, associated with postoperative complications, as well as the rate of reoperation with regard to mandible angle fractures. Retrospective cohort study analyzing the surgical outcomes of patients with mandible angle fractures between January 1, 2000, and December 31, 2015, who underwent open reduction and internal fixation. Patients were eligible if they were aged 18 years or older, had 3 or less mandible fractures with 1 involving the mandibular angle, and had adequate follow-up data. Patients with comminuted angle fractures, bilateral angle fractures, and multiple surgical approaches were excluded. A total of 135 patients were included in the study. All procedures were conducted at a single, large academic hospital located in an urban setting. Major complications and reoperation rates. Major complications included in this study were nonunion, malunion, severe malocclusion, severe infection, and exposed hardware. Of 135 patients 113 (83.7%) were men; median age was 29 years (range, 18-82 years). Eighty-seven patients (64.4%) underwent the transcervical approach and 48 patients (35.6%) received the transoral approach. Fifteen (17.2%) patients in the transcervical group and 9 (18.8%) patients in the transoral group experienced major complications (difference, 1%; 95% CI, -8% to 10%). Thirteen (14.9%) patients in the transcervical group and 8 (16.7%) patients in the transoral group underwent reoperations (difference, 2%; 95% CI, -13% to 17%). Active smoking had a significant effect on the rate of major complications (odds ratio, 4.04; 95% CI, 1.07 to 15.34; P = .04). During repair of noncomminuted mandibular angle fractures, both of the commonly used approaches-transcervical and transoral-can be used during treatment with equal

    Full Text Available Splenic abscess is one of the rarest complications of the UVC in a newborn and it is hypothesized that it could be due to an infection or trauma caused by a catheter. The case that is being reported presented with abdominal distension and recurrent desaturation with suspicion of neonatal sepsis versus necrotizing enterocolitis. However, the final diagnosis was splenic abscess as a complication of an inappropriate UVC insertion which was discovered by abdominal ultrasound. The patient was given broad spectrum antibiotics empirically and the symptoms were resolved without any surgical intervention. Such cases and controlled studies need to be reported in order to identify further causes and risk factors associated with splenic abscess in a patient with UVC which can eventually help us adopt preventive strategies to avoid such complications.

    Antibiotics are the recommended first-line treatment for Mycobacterium ulcerans disease. Antibiotic toxicity is common in Australian patients, yet antibiotic complication rates and their risk factors have not been determined. To determine the incidence rate and risk factors for antibiotic toxicity in Australian patients treated for M. ulcerans disease. An analysis of severe antibiotic complications was performed using data from a prospective cohort of M. ulcerans cases managed at Barwon Health from 1 January 1998 to 30 June 2016. A severe antibiotic complication was defined as an antibiotic adverse event that required its cessation. Antibiotic complication rates and their associations were assessed using a Poisson regression model. A total of 337 patients was included; 184 (54.6%) males and median age 57 years (interquartile range (IQR) 36-73 years). Median antibiotic treatment duration was 56 days (IQR 49-76 days). Seventy-five (22.2%) patients experienced severe antibiotic complications after a median 28 days (IQR 17-45 days) at a rate of 141.53 per 100 person-years (95% confidence interval (CI) 112.86-177.47). Eleven (14.7%) patients required hospitalisation. Compared with rifampicin/clarithromycin combinations, severe complication rates were not increased for rifampicin/ciprofloxacin (rate ratio (RR) 1.49, 95% CI 0.89-2.50, P = 0.13) or rifampicin/moxifloxacin (RR 2.54, 95% CI 0.76-8.50, P = 0.13) combinations, but were significantly increased for 'other' combinations (RR 2.53, 95% CI 1.13-5.68, P = 0.03). In a multivariable analysis, severe complication rates were significantly increased with reduced estimated glomerular filtration rates (EGFR) (adjusted rate ratio (aRR) 2.65, 95% CI 1.24-5.65 for EGFR 60-89 mL/min and aRR 1.31, 95% CI 0.49-3.53 for EGFR 0-59 mL/min compared with EGFR ≥90 mL/min, P antibiotic complications during M. ulcerans treatment are high with increased rates independently associated with reduced renal function and female

    The prevalence of chronic vascular complications is higher in patients with type 2 diabetes mellitus (DM2). The objective of our cross-sectional study was to assess the incidence and types of macrovascular (MVC) and microvascular (mvc) complications and to analyse their relation to the different risk factors and biomarkers in order to improve their prevention. 415 patients (219 men and 196 women) with an average age of 66 +/- 9 years enrolled in the study. A total of 95% of patients with DM2 had a history of hypertension, 27% had MVC (of which 55% had ischaemic heart disease), and 54% had mvc (ofwhich 95% had diabetic nephropathy). The patients with vascular complications were significantly older and had a longer history of DM2; they did not differ for their systolic blood pressure, but had a higher pulse pressure and took more antihypertensives. They did not differ for their lipid levels or the respective therapy. Diabetic patients with MVC and mvc had higher insulin resistance, higher plasmatic levels of total homocysteine and a higher incidence ofalbuminuria or proteinuria. The factors which significantly and independently associated with MVC were male gender, age over 60 years, higher hs-C-reactive protein (hs-CRP) exceeding 1 mg/l, glycaemia over 5.6 mmol/l, lower diastolic blood pressure and lower HDL-cholesterol; mvc associated with higher age over 60 years, a history of DM2 exceeding 8 years, and hs-CRP above 1 mg/l. Our results show that patients with DM2 have a high incidence ofvascular complications significantly associated with age, DM2 history and higher hs-CRP, irrespective of the other monitored parametres.

    Background/Aims/Objectives: To analyze perioperative complication and short-term explantation rates after perineal or penoscrotal single-cuff and double-cuff artificial urinary sphincter (AUS) implantation in a large middle European multi-institutional patient cohort. 467 male patients with stress urinary incontinence underwent implantation of a perineal single-cuff (n = 152), penoscrotal single-cuff (n = 99), or perineal double-cuff (n = 216) AUS between 2010 and 2012. Postoperative complications and 6-month explantation rates were assessed. For statistical analysis, Fisher's exact test and Kruskal-Wallis rank sum test, and a multiple logistic regression model were used (p AUS, penoscrotal single-cuff implantation led to significantly increased short-term explantation rates (8.6% (perineal) vs. 19.2% (penoscrotal), p = 0.019). The postoperative infection rate was significantly higher after double-cuff compared to single-cuff implantation (6.0% (single-cuff) vs. 13.9% (double-cuff), p = 0.019). The short-term explantation rate after primary double-cuff placement was 6.5% (p = 0.543 vs. perineal single-cuff). In multivariate analysis, the penoscrotal approach (p = 0.004), intraoperative complications (p = 0.005), postoperative bleeding (p = 0.011), and perioperative infection (p < 0.001) were independent risk factors for short-term explantation. Providing data from a large contemporary multi-institutional patient cohort from high-volume and low-volume institutions, our results reflect the current standard of care in middle Europe. We indicate that the penoscrotal approach is an independent risk factor for increased short-term explantation rates. © 2016 S. Karger AG, Basel.

    Stricturing and penetrating complications account for substantial morbidity and health-care costs in paediatric and adult onset Crohn's disease. Validated models to predict risk for complications are not available, and the effect of treatment on risk is unknown. We did a prospective inception cohort study of paediatric patients with newly diagnosed Crohn's disease at 28 sites in the USA and Canada. Genotypes, antimicrobial serologies, ileal gene expression, and ileal, rectal, and faecal microbiota were assessed. A competing-risk model for disease complications was derived and validated in independent groups. Propensity-score matching tested the effect of anti-tumour necrosis factor α (TNFα) therapy exposure within 90 days of diagnosis on complication risk. Between Nov 1, 2008, and June 30, 2012, we enrolled 913 patients, 78 (9%) of whom experienced Crohn's disease complications. The validated competing-risk model included age, race, disease location, and antimicrobial serologies and provided a sensitivity of 66% (95% CI 51-82) and specificity of 63% (55-71), with a negative predictive value of 95% (94-97). Patients who received early anti-TNFα therapy were less likely to have penetrating complications (hazard ratio [HR] 0·30, 95% CI 0·10-0·89; p=0·0296) but not stricturing complication (1·13, 0·51-2·51; 0·76) than were those who did not receive early anti-TNFα therapy. Ruminococcus was implicated in stricturing complications and Veillonella in penetrating complications. Ileal genes controlling extracellular matrix production were upregulated at diagnosis, and this gene signature was associated with stricturing in the risk model (HR 1·70, 95% CI 1·12-2·57; p=0·0120). When this gene signature was included, the model's specificity improved to 71%. Our findings support the usefulness of risk stratification of paediatric patients with Crohn's disease at diagnosis, and selection of anti-TNFα therapy.

    Hysterosalpingography (HSG), a standard procedure for the evaluation of women with infertility and repetitive pregnancy loss, is associated with complications such as uterine perforation, infection, allergic reactions, syncope, hemorrhage and shock, and pulmonary or retinal embolus. However, hyperthyroidism has not been reported as one of its complications. We report the case of a 33-year-old euthyroid woman who presented to our hospital with palpitation, hand tremor, fatigue, and excessive sweating after HSG. Thyroid function tests revealed a thyroid stimulating hormone (TSH) level of 0.012 μIU/mL (range 0.38-4.34 μIU/mL), free T4 of 2.886 ng/dL (range 0.81-1.89 ng/dL), and free T3 levels of 9.4 pg/mL (range 1.80-4.10 pg/mL), and antithyroglobulin antibody of 31.78 IU/mL (range hyperthyroidism (IIH), but was not treated with antithyroid drugs. She has spontaneously recovered and is pregnant currently. This is the first reported case of overt IIH caused by HSG in a euthyroid patient without risk factors. It suggests that HSG also leads to excessive iodine absorption, which induces secondary hyperthyroidism.

    The authors studied the records of 46 patients who had been operated on between 1974 and 1990 in the Netherlands Cancer Institute because of complications due to late radiation damage of the small bowel. The following factors led to an increase in complication-risk: hypalbuminemia. more than one laparotomy prior to irradiation and a short interval (< 12 months) between irradiation and surgical intervention. The following factors related to a poorer survival: incomplete resection of the primary tumor and a short interval (< 12 months) between irradiation and surgical intervention. The type f surgical intervention did not have cumulative prognostic value in relation to complication-risk or survival. (author)

    Little is known about risk factors for complications in chronic pancreatitis (CP). High fat diet (HFD) has been demonstrated to aggravate pancreatic injury in animal models. The aim of this study was to investigate the role of HFD in age at diagnosis of CP and probability of CP related complications. A cross-sectional case-case study was performed within a prospectively collected cohort of patients with CP. Diagnosis and morphological severity of CP was established by endoscopic ultrasound. Pancreatic exocrine insufficiency (PEI) was diagnosed by ¹³C mixed triglyceride breath test. Fat intake was assessed by a specific nutritional questionnaire. Odds ratios (OR) for CP related complications were estimated by multivariate logistic regression analysis. 168 patients were included (128 (76.2%) men, mean age 44 years (SD 13.5)). Etiology of CP was alcohol abuse in 89 patients (53.0%), other causes in 30 (17.9%) and idiopathic in the remaining 49 subjects (29.2%). 24 patients (14.3%) had a HFD. 68 patients (40.5%) had continuous abdominal pain, 39 (23.2%) PEI and 43 (25.7%) morphologically severe CP. HFD was associated with an increased probability for continuous abdominal pain (OR = 2.84 (95% CI, 1.06-7.61)), and a younger age at diagnosis (37.0 ± 13.9 versus 45.8 ± 13.0 years, p = 0.03) but not with CP related complications after adjusting for sex, years of follow-up, alcohol and tobacco consumption, etiology and body mass index. Compared with a normal fat diet, HFD is associated with a younger age at diagnosis of CP and continuous abdominal pain, but not with severity and complications of the disease.

    Purpose: Our aim was to investigate the association of clinical factors, dosimetric parameters, and biomarkers with postoperative pulmonary complications (PPCs) in patients with locally advanced esophageal squamous cell carcinoma (ESCC) treated by neoadjuvant concurrent chemoradiation therapy (CCRT) under strict pulmonary dose constraints and esophagectomy. Methods and Materials: We prospectively enrolled 112 patients undergoing trimodality treatment (including radiation therapy [40 Gy], concurrent taxane-/5-fluorouracil-based regimens, and radical esophagectomy) for ESCC. A PPC was defined as pneumonia or acute respiratory distress syndrome within 30 days after surgery. Serum samples were collected before and within 1 month after CCRT. The association of serum biomarkers with PPCs was detected by proximity ligation assay (PLA) and verified by enzyme-linked immunosorbent assay. Associations of clinical factors, lung dosimetric parameters, and biomarkers with PPC were tested statistically. Results: Thirty-three patients (29.5%) had PPCs. None of the dosimetric parameters was associated with PPCs. Preoperative functional vital capacity (FVC) was significantly associated with PPCs (P=.004). Of the 15 PLA-screened biomarkers, posttreatment transforming growth factor-β1 (TGF-β1) was borderline significantly associated with PPCs (P=.087). Patients with PPCs had significantly larger pre-CCRT to post-CCRT decrease in serum TGF-β1 concentration (−11,310 vs −5332 pg/mL, P=.005) and higher pre-CCRT to post-CCRT percent decline in serum TGF-β1 concentration (−37.4% vs −25.0%, P=.009) than patients without PPCs. On multivariate analysis, preoperative FVC (P=.003) and decrease in TGF-β1 >7040 pg/mL (P=.014) were independent factors associated with PPCs. Conclusions: Preoperative FVC and decrease in serum TGF-β1 level after dose-limited CCRT to the lung are associated with the development of PPCs.

    The refeeding syndrome is a life-threatening complication that can occur after initiation of a nutrition therapy in malnourished patients. If the risk factors and pathophysiology are known, the refeeding syndrome can effectively be prevented and treated, if recognized early. A slow increase of food intake and the close monitoring of serum electrolyte levels play an important role. Because the refeeding syndrome is not well known and the symptoms may vary extremely, this complication is poorly recognized, especially against the background of geriatric multimorbidity. This overview is intended to increase the awareness of the refeeding syndrome in the risk group of geriatric patients.

  2. A Third Moment Adjusted Test Statistic for Small Sample Factor Analysis.

    Science.gov (United States)

    Lin, Johnny; Bentler, Peter M

    2012-01-01

    Goodness of fit testing in factor analysis is based on the assumption that the test statistic is asymptotically chi-square; but this property may not hold in small samples even when the factors and errors are normally distributed in the population. Robust methods such as Browne's asymptotically distribution-free method and Satorra Bentler's mean scaling statistic were developed under the presumption of non-normality in the factors and errors. This paper finds new application to the case where factors and errors are normally distributed in the population but the skewness of the obtained test statistic is still high due to sampling error in the observed indicators. An extension of Satorra Bentler's statistic is proposed that not only scales the mean but also adjusts the degrees of freedom based on the skewness of the obtained test statistic in order to improve its robustness under small samples. A simple simulation study shows that this third moment adjusted statistic asymptotically performs on par with previously proposed methods, and at a very small sample size offers superior Type I error rates under a properly specified model. Data from Mardia, Kent and Bibby's study of students tested for their ability in five content areas that were either open or closed book were used to illustrate the real-world performance of this statistic.

    As appendicitis in children can be managed differently according to the severity of the disease, we investigated whether commonly used serum biomarkers on admission could distinguish between simple and complicated appendicitis. Admission white blood cell (WBC), neutrophil (NEU), and C-reactive protein (CRP) levels were analysed by ROC curve, and Kruskal-Wallis and contingency tests. Patients were divided according to age and histology [normal appendix (NA), simple appendicitis (SA), complicated appendicitis (CA)]. Of 1197 children (NA = 186, SA = 685, CA = 326), 7% were 40 mg/L in 58% CA and 37% SA (p 15 × 10 9 /L in 58% CA and 43% SA (p appendicitis in children older than 5 years of age. Early distinction of appendicitis severity using these tests may guide caregivers in the preoperative decision-making process.

    The aim of this study was to establish whether smoking is associated with complicated diverticular disease and adverse outcomes of operative treatment of diverticular disease. Smoking has been associated with increased rate of perforations in acute appendicitis as well as failure of colonic anastomosis in patients resected for colonic tumours. It has also been suggested that smoking is a risk factor for complicated diverticular disease of the colon. Retrospective investigation of records of 261 patients electively operated for diverticular disease in Helsinki University Central Hospital during a period of five years. The smokers underwent sigmoidectomy at a younger age than the non-smokers (p = 0.001) and they had an increased rate of perforations (p = 0.040) and postoperative recurrent diverticulitis episodes (p = 0.019). We conclude that smoking increases the likelihood of complications in diverticulosis coli. The development of complicated disease also seems to proceed more rapidly in smokers.Key words: Sigmoid resection; laparoscopy; laparoscopic sigmoidectomy; smoking and diverticular disease; complicated diverticular disease; diverticulitis.

    Purpose. To determine the incidence of neurologic complications of cerebral angiography in children with moyamoya syndrome (MMS) as compared to children without MMS. Materials and methods. One-hundred-ninety consecutive cerebral angiograms obtained in 152 children were evaluated. Sixty of these angiograms were obtained in 40 children with MMS. Patients underwent neurologic evaluation prior to and after the procedure. For this study, a neurologic complication was defined as any new focal neurologic deficit or alteration in mental status occurring during the procedure or within the ensuing 24 hours. Results. There were 2 neurologic complications within 24 hours of angiography, one in the MMS group and one in the non-MMS group. One patient with MMS became mute following angiography. The symptom resolved within 12 hours. One patient without MMS being examined postoperatively for residual arteriovenous malformation developed intracranial hemorrhage requiring reexploration 12 hours after the angiogram. Using a two-tail Fisher's exact test, there was no significant statistical difference in the ischemic (P = 0.3) or hemorrhagic (P = 1.0) complication rates between the group of patients with MMS and the non-MMS groups. Conclusion. The risk of a neurologic complication from cerebral angiography in children with MMS is low and not statistically different from the risk in children with other cerebrovascular disorders.

    Full Text Available BACKGROUND: Since the evolution of multi-drug chemotherapy and radiotherapy and new sophisticated surgical techniques, limb salvage and reconstruction, rather than amputation, has become the preferred treatment for patients with bone tumors. One option is allograft replacement. Although allograft has several advantages, it is not without complications. This study was performed to observe these complications in a group of patients treated with allograft replacement for bone tumor resection. The purpose was to gain an overview of the factors predisposing to these complications to minimize their occurrence. METHODS: This retrospective study was performed on patients with benign aggressive and malignant bone tumors undergoing limb reconstruction with allograft between 1997 and 2005 in Al-Zahra and Kashani Hospitals in Isfahan, Iran. Data was collected from patient files, clinical notes, radiographs and a recent physical examination. Complications including local recurrence, fracture of allograft, fixation failure, nonunion, infection, skin necrosis and neurological damage were recorded. RESULTS: Sixty patients including 39 males and 21 females were studied. The mean age of patients was 23 ± 11.7 years. The mean follow-up interval was 28.1 ± 12.4 months (mean ± SD. Complications were allograft fracture in 20%, local recurrence in 16%, fixation failure in 11%, nonunion in 6%, infection in 6%, skin necrosis in 6%, and peroneal nerve palsy in 1% of cases. Most local recurrences (60% were those with a mal-performed biopsy. Most allograft fractures occurred when a short plate was used. CONCLUSIONS: Allograft replacement for bone tumors remains a valid option. To avoid complications, biopsy should be done by a trained surgeon in bone oncology. A long plate is recommended for fixation. Sterility and graft processing must be optimal. Autogenous bone graft must be added at host-allograft junction. KEY WORDS: Bone tumors, bone allograft, limb

    1990-01-01

    No part of the body reflects the complications of cancer chemotherapy as visibly and as vividly as the mouth. The infectious, hemorrhagic, cytotoxic, nutritional, and neurologic signs of drug toxicity are reflected in the mouth by changes in the color, character, comfort, and continuity of the mucosa. The stomatologic complications of radiotherapy for oral cancer are physical and physiological in nature, transient or lasting in duration, and reversible or irreversible in type. Some linger as permanent mementos long after the cancer has been destroyed. They stem from radiation injury to the salivary glands, oral mucosa, oral musculature, alveolar bone, and developing teeth. They are expressed clinically by xerostomia, trismus, radiation dermatitis, nutritional stomatitis, and dentofacial malformation. In both cancer chemotherapy and cancer radiotherapy, the oral complications vary in pattern, duration, intensity, and number, with not every patient developing every complication. 21 references

    To evaluate complications and identify risk factors for adverse events in patients undergoing high-dose-rate interstitial brachytherapy (iBT). Data from 192 patients treated in 343 CT- or MRI-guided interventions from 2006-2009 at our institution were analyzed. In 41 %, the largest tumor treated was ≥ 5 cm, 6 % of the patients had tumors ≥ 10 cm. Prior to iBT, 60 % of the patients had chemotherapy, 22 % liver resection, 19 % thermoablation or transarterial chemoembolization (TACE). Safety was the primary endpoint; survival data were obtained as the secondary endpoints. During follow-up, MRI or CT imaging was performed and clinical and laboratory parameters were obtained. The rate of major complications was below 5 %. Five major bleedings (1.5 %) occurred. The frequency of severe bleeding was significantly higher in patients with advanced liver cirrhosis. One patient developed signs of a nonclassic radiation-induced liver disease. In 3 patients, symptomatic gastrointestinal (GI) ulcers were detected. A dose exposure to the GI wall above 14 Gy/ml was a reliable threshold to predict ulcer formation. A combination of C-reactive protein ≥ 165 mg/l and/or leukocyte count ≥ 12.7 Gpt/l on the second day after the intervention predicted infection (sensitivity 90.0 %; specificity 92.8 %.) Two patients (0.6 %) died within 30 days. Median overall survival after the first liver treatment was 20.1 months for all patients and the local recurrence-free surviving proportion was 89 % after 12 months. Image-guided iBT yields a low rate of major complications and is effective. (orig.)

    Martin, Robert C G; Brennan, Murray F; Jaques, David P

    2002-06-01

    To identify 10 critical elements of accurate and comprehensive reports of surgical complications. Despite a venerable tradition of weekly morbidity and mortality conferences, inconsistent complication reporting is common in the surgical literature. An analysis of articles reporting short-term outcomes after pancreatectomy, esophagectomy, and hepatectomy was performed. Randomized clinical trials (RCTs) published from 1975 to 2001 and retrospective series of more than 100 patients published from 1990 to 2001 were reviewed. A total of 119 articles reporting outcomes in 22,530 patients were analyzed. This included 42 RCTs and 77 retrospective series. Of the 10 criteria developed, no articles met all criteria; 2% met 9 criteria, 38% 7 or 8, 34% 5 or 6, 40% 3 or 4, and 12% 1 or 2. Outpatient information (22% of articles), definitions of complications provided (34% of articles), severity grade used (20% of articles), and risk factors included in analysis (29% of articles) were the most commonly unmet quality reporting criteria. Type of study (RCT vs. retrospective), site of institution (U.S. vs. non-U.S.) and journal (U.S. vs. non-U.S.) did not influence the quality of complication reporting. Short-term surgical outcomes are routinely included in the data reported in the surgical literature. This is often used to show improvements over time or to assess the impact of therapeutic changes on patient outcome. The inconsistency of reporting and the lack of accepted principles of accrual, display, and analysis of complication data argue strongly for the creation and generalized use of standards for reporting this information.

  14. Complications associated with orthognathic surgery

    Science.gov (United States)

    2017-01-01

    While most patients undergo orthognathic surgery for aesthetic purposes, aesthetic improvements are most often followed by postoperative functional complications. Therefore, patients must carefully decide whether their purpose of undergoing orthognathic surgery lies on the aesthetic side or the functional side. There is a wide variety of complications associated with orthognathic surgery. There should be a clear distinction between malpractice and complications. Complications can be resolved without any serious problems if the cause is detected early and adequate treatment provided. Oral and maxillofacial surgeons must have a full understanding of the types, causes, and treatment of complications, and should deliver this information to patients who develop these complications.

    In the interests of improving maternal health care and survival, the issue of birth preparedness and complication readiness has been much debated and has remained a priority for the international health community. The provision of birth preparedness and complications readiness is determined by a range of different factors. The main aim of this study is to identify and measure the influence of husbands and other family relationships on birth preparedness and complications readiness in the Khyber Pakhtunkhwa province of Pakistan. This study is a cross-sectional exploratory study. Data was collected through a survey questionnaire. Logistic regression and descriptive analysis was used. Analysis indicated that the mother-in-law's role, men's and women's level of education and interfamilial relationships are still the most significant factors influencing birth preparedness and complications readiness. Of the respondents, 86% were receiving antenatal care and 76.5% were planning for the birth to take place in state-run hospitals or private obstetric and gynae clinics. The tendency to take up antenatal care in Khyber Pakhtunkhwa can mainly be credited to a mutual understanding between husband and wife and a good relationship between the woman and her mother-in-law. Highlighting the significance of these relationships has implications for ensuring birth preparedness and complications readiness. Copyright © 2018 Australian College of Midwives.

    A multicenter retrospective case series. Horner's syndrome is a known complication of anterior cervical spinal surgery, but it is rarely encountered in clinical practice. To better understand the incidence, risks, and neurologic outcomes associated with Horner's syndrome, a multicenter study was performed to review a large collective experience with this rare complication. We conducted a retrospective multicenter case series study involving 21 high-volume surgical centers from the AOSpine North America Clinical Research Network. Medical records for 17 625 patients who received subaxial cervical spine surgery from 2005 to 2011 were reviewed to identify occurrence of 21 predefined treatment complications. Descriptive statistics were provided for baseline patient characteristics. Paired t test was used to analyze changes in clinical outcomes at follow-up compared to preoperative status. In total, 8887 patients who underwent anterior cervical spine surgery at the participating institutions were screened. Postoperative Horner's syndrome was identified in 5 (0.06%) patients. All patients experienced the complication following anterior cervical discectomy and fusion. The sympathetic trunk appeared to be more vulnerable when operating on midcervical levels (C5, C6), and most patients experienced at least a partial recovery without further treatment. This collective experience suggests that Horner's syndrome is an exceedingly rare complication following anterior cervical spine surgery. Injury to the sympathetic trunk may be limited by maintaining a midline surgical trajectory when possible, and performing careful dissection and retraction of the longus colli muscle when lateral exposure is necessary, especially at caudal cervical levels.

    2015-01-01

    The purpose of this study was to retrospectively evaluate the diagnostic accuracy and complications of CT-guided core needle biopsy (CT-guided CNB) of pleural lesion and the possible effects of influencing factors. From September 2007 to June 2013, 88 consecutive patients (60 men and 28 women; mean [+/- standard deviation] age, 51.1 +/- 14.4 years; range, 19-78 years) underwent CT-guided CNB, which was performed by two experienced chest radiologists in our medical center. Out of 88 cases, 56 (63%) were diagnosed as malignant, 28 (31%) as benign and 4 (5%) as indeterminate for CNB of pleural lesions. The final diagnosis was confirmed by either histopathological diagnosis or clinical follow-up. The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and complication rates were statistically evaluated. Influencing factors (patient age, sex, lesion size, pleural-puncture angle, patient position, pleural effusion, and number of pleural punctures) were assessed for their effect on accuracy of CT-guided CNB using univariate and subsequent multivariate analysis. Diagnostic accuracy, sensitivity, specificity, PPV, and NPV were 89.2%, 86.1%, 100%, 100%, and 67.8%, respectively. The influencing factors had no significant effect in altering diagnostic accuracy. As far as complications were concerned, occurrence of pneumothorax was observed in 14 (16%) out of 88 patients. Multivariate analysis revealed lesion size/pleural thickening as a significant risk factor (odds ratio [OR]: 8.744, p = 0.005) for occurrence of pneumothorax. Moreover, presence of pleural effusion was noted as a significant protective factor (OR: 0.171, p = 0.037) for pneumothorax. CT-guided CNB of pleural lesion is a safe procedure with high diagnostic yield and low risk of significant complications.

    The purpose of this study was to retrospectively evaluate the diagnostic accuracy and complications of CT-guided core needle biopsy (CT-guided CNB) of pleural lesion and the possible effects of influencing factors. From September 2007 to June 2013, 88 consecutive patients (60 men and 28 women; mean [+/- standard deviation] age, 51.1 +/- 14.4 years; range, 19-78 years) underwent CT-guided CNB, which was performed by two experienced chest radiologists in our medical center. Out of 88 cases, 56 (63%) were diagnosed as malignant, 28 (31%) as benign and 4 (5%) as indeterminate for CNB of pleural lesions. The final diagnosis was confirmed by either histopathological diagnosis or clinical follow-up. The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and complication rates were statistically evaluated. Influencing factors (patient age, sex, lesion size, pleural-puncture angle, patient position, pleural effusion, and number of pleural punctures) were assessed for their effect on accuracy of CT-guided CNB using univariate and subsequent multivariate analysis. Diagnostic accuracy, sensitivity, specificity, PPV, and NPV were 89.2%, 86.1%, 100%, 100%, and 67.8%, respectively. The influencing factors had no significant effect in altering diagnostic accuracy. As far as complications were concerned, occurrence of pneumothorax was observed in 14 (16%) out of 88 patients. Multivariate analysis revealed lesion size/pleural thickening as a significant risk factor (odds ratio [OR]: 8.744, p = 0.005) for occurrence of pneumothorax. Moreover, presence of pleural effusion was noted as a significant protective factor (OR: 0.171, p = 0.037) for pneumothorax. CT-guided CNB of pleural lesion is a safe procedure with high diagnostic yield and low risk of significant complications.

    Full Text Available Intrauterine inflammation has been associated with preterm birth and neonatal complications. Few reports have comprehensively investigated multiple cytokine profiles in cord blood and precisely identified surrogate markers for intrauterine inflammation.To identify the cytokines and surrogate markers associated with intrauterine inflammation and subsequent neonatal complications.We analyzed cord blood samples from 135 patients admitted to the neonatal intensive care unit at Sasebo City General Hospital. We retrospectively determined the associations between the presence of neonatal complications and cord blood cytokines, prenatal factors, and laboratory data at birth. A total of 27 cytokines in the cord blood were measured using a bead-based array sandwich immunoassay.Both Th1 and Th2 cytokine levels were low, whereas the levels of growth factors and chemokines were high. In particular, chemokines IL-8, MCP-1, and MIP-1α were significantly higher in very premature neonates when compared with more mature neonates. In addition, some have been shown to be associated with multiple neonatal complications, including patent ductus arteriosus (PDA, respiratory distress syndrome (RDS, and chronic lung disease (CLD. Similarly, the levels of N-terminal pro-brain natriuretic peptide, nucleated RBC, and urinary β2-microglobulin were associated with these complications and chemokine levels.Our results suggest the association of inflammatory chemokines IL-8, MCP-1, and MIP-1α with intrauterine inflammation, premature birth, and neonatal complications in these perinatal subjects. Furthermore, the association of the aforementioned biomarkers with PDA, RDS, and CLD may help establish early diagnostic measures to predict such neonatal complications following intrauterine inflammation.
