    The objective of the present study was to estimate the prevalence of the different pathological conditions causing clinically evident androgen excess and to document the degree of long-term success of suppressive and/or antiandrogen hormonal therapy in a large consecutive population of patients. All patients presenting for evaluation of symptoms potentially related to androgen excess between October 1987 and June 2002 were evaluated, and the data were maintained prospectively in a computerized database. For the assessment of therapeutic response, a retrospective review of the medical chart was performed, after the exclusion of those patients seeking fertility therapy only, or with inadequate follow-up or poor compliance. A total of 1281 consecutive patients were seen during the study period. Excluded from analysis were 408 patients in whom we were unable to evaluate hormonal status, determine ovulatory status, or find any evidence of androgen excess. In the remaining population of 873 patients, the unbiased prevalence of androgen-secreting neoplasms was 0.2%, 21-hydroxylase-deficient classic adrenal hyperplasia (CAH) was 0.6%, 21-hydroxylase-deficient nonclassic adrenal hyperplasia (NCAH) was 1.6%, hyperandrogenic insulin-resistant acanthosis nigricans (HAIRAN) syndrome was 3.1%, idiopathic hirsutism was 4.7%, and polycystic ovary syndrome (PCOS) was 82.0%. Fifty-nine (6.75%) patients had elevated androgen levels and hirsutism but normal ovulation. A total of 257 patients were included in the assessment of the response to hormonal therapy. The mean duration of follow-up was 33.5 months (range, 6-155). Hirsutism improved in 86%, menstrual dysfunction in 80%, acne in 81%, and hair loss in 33% of patients. The major side effects noted were irregular vaginal bleeding (16.1%), nausea (13.0%), and headaches (12.6%); only 36.6% of patients never complained of side effects. In this large study of consecutive patients presenting with clinically evident androgen excess

    Full Text Available Aspiration can cause a diverse spectrum of pulmonary disorders some of which can lead to death but can be difficult to diagnose.The medical records and autopsy findings of 57 consecutive patients in whom aspiration was the immediate cause of death at Mayo Clinic (Rochester, MN, USA over a 9-yr period, from January 1 2004 to December 31 2012 were analyzed.The median age at death was 72 years (range, 13-95 years and included 39 (68% males. The most common symptom before death was dyspnea (63% and chest radiography revealed bilateral infiltrates in the majority (81%. Most common precipitating factors for aspiration were depressed consciousness (46% and dysphagia (44%. Aspiration-related syndromes leading to death were aspiration pneumonia in 26 (46%, aspiration pneumonitis in 25 (44%, and large airway obstruction in 6 patients (11%. Aspiration was clinically unsuspected in 19 (33% patients. Antimicrobial therapy had been empirically administered to most patients (90% with aspiration pneumonia and aspiration pneumonitis.We conclude aspiration-related deaths occur most commonly in the elderly with identifiable risks and presenting bilateral pulmonary infiltrates. One-third of these aspiration-related pulmonary syndromes were clinically unsuspected at the time of death.

    Recent population-based studies have shown a low risk of esophageal adenocarcinoma (EAC) in patients with nondysplastic Barrett's esophagus (NDBE). We evaluated whether persistence of NDBE over multiple consecutive surveillance endoscopic examinations could be used in risk stratification of patients with Barrett's esophagus (BE). We performed a multicenter outcomes study of a large cohort of patients with BE. Based on the number of consecutive surveillance endoscopies showing NDBE, we identified 5 groups of patients. Patients in group 1 were found to have NDBE at their first esophagogastroduodenoscopy (EGD). Patients in group 2 were found to have NDBE on their first 2 consecutive EGDs. Similarly, patients in groups 3, 4, and 5 were found to have NDBE on 3, 4, and 5 consecutive surveillance EGDs. A logistic regression model was built to determine whether persistence of NDBE independently protected against development of cancer. Of a total of 3515 patients with BE, 1401 patients met the inclusion criteria (93.3% white; 87.5% men; median age, 60 ±17 years). The median follow-up period was 5 ± 3.9 years (7846 patient-years). The annual risk of EAC in groups 1 to 5 was 0.32%, 0.27%, 0.16%, 0.2%, and 0.11%, respectively (P for trend = .03). After adjusting for age, sex, and length of BE, persistence of NDBE, based on multiple surveillance endoscopies, was associated with a gradually lower likelihood of progression to EAC. Persistence of NDBE over several endoscopic examinations identifies patients who are at low risk for development of EAC. These findings support lengthening surveillance intervals or discontinuing surveillance of patients with persistent NDBE. Copyright © 2013 AGA Institute. Published by Elsevier Inc.

    Microbleeds on T2 * -weighted magnetic resonance imaging (MRI) represent a hemorrhagic type of small vessel disease. Small vessel disease causes both intracerebral hemorrhages and lacunar infarctions. We studied clinical background and MRI findings of the patients to clarify the correlation between microbleeds and lacunes. This study consisted of 180 consecutive patients who underwent brain MRI using 1.5T system in our hospital for a year. We obtained T2 * -weighted gradient-echo imaging as well as T1 and T2-weighted images. We statistically identified the factors related to the presence of microbleeds in all patients. The distribution of lacunes and microbleeds on MRI was compared to clarify the correlation of the lesions in the patients who had both lesions. The overall prevalence of microbleeds was 41.1% (74 of 180 patients). Logistic regression analysis indicated that previous stroke, leukoaraiosis and lacunes were significantly correlated with microbleeds. In the patients who have both microbleeds and lacunes, lesions are tended to locate in thalamus and basal ganglia, especially incidence of lacunes are significantly greater compared with other regions. Thirty-six of 398 lesions (9.05%) diagnosed as lacunes with T1- and T2-weighted imaging were demonstrated as microbleeds with T2 * -weighted gradient-echo imaging. Lacunes, leukoaraiosis as a hypertensive change on MRI had statistically significant correlation with the presence of microbleeds. T2 * -weighted gradient-echo imaging should be included in the imaging protocol for cerebrovascular disease, because T1- and T2-weighted imaging recognizing some of the microbleeds as lacunar infarction.

    2010-11-01

    Full Text Available Abstract Background Femoral access is a fundamental element of catheter-based cerebral angiography. Knowledge of location of the common femoral artery (CFA bifurcation is important as the risk of retroperitoneal bleeding is increased if the puncture is superior to the inguinal ligament and there is an increased risk of thrombosis and arteriovenous fistula formation if the puncture is distal into branch vessels. We sought to characterize the location of the CFA bifurcation along with the presence of significant atherosclerosis or iliac tortuosity in a contemporary series of subarachnoid hemorrhage (SAH patients. Findings The records of a prospective single-center aneurysm database were reviewed to identify 100 consecutive SAH patients. Using an oblique femoral arteriogram, the presence of significant atherosclerosis, iliac tortuosity, and the CFA bifurcation were assessed. The CFA bifurcation was graded according to its position with respect to the femoral head: below (grade 1, lower half (grade 2, and above the upper half (grade 3. We found a CFA bifurcation grade 1 in 50 patients (50%, mean age 51.2 years, grade 2 in 40 patients (40%, mean age 55.5 years, and grade 3 in 10 patients (10%, mean age 58.2 years. Whereas 30 of 90 patients with CFA grades I or II were male (33%, only 10% with grade 3 were male (1 of 10, p = 0.12. Mean age for significant atherosclerosis was 65.5 +/- 2.6 years versus 50.9 +/- 1.6 years (p Conclusions Although a requisite element of endovascular treatment in SAH patients, femoral access can be complicated by a high common femoral artery bifurcation and the presence of atherosclerotic disease and/or iliac artery tortuosity. In this study, we found a grade 3 (above the femoral head CFA bifurcation in 10% patients, with 90% of these patients being female. We also found the presence of atherosclerotic disease and iliac tortuosity to be significantly more likely in patients older than 65 years of age.

    Is there a different prognostic impact for consecutive and non-consecutive early pregnancy losses in women with secondary recurrent pregnancy loss (RPL)? Only consecutive early pregnancy losses after the last birth have a statistically significant negative prognostic impact in women with secondary RPL. The risk of a new pregnancy loss increases with the number of previous pregnancy losses in patients with RPL. Second trimester losses seem to exhibit a stronger negative impact than early losses. It is unknown whether the sequence of pregnancy losses plays a role for the prognosis in patients with a prior birth. This retrospective cohort study of pregnancy outcome in patients with unexplained secondary RPL included in three previously published, Danish double-blinded placebo-controlled trials of intravenous immunoglobulin (IvIg) conducted from 1991 to 2014. No other treatments were given. Patients with documented explained pregnancy losses (ectopic pregnancies and aneuploid miscarriages) were excluded. Of the 168 patients included in the trials, 127 had secondary RPL and experienced a subsequent live birth or unexplained pregnancy loss in the first pregnancy after giving informed consent to participate in the trials (the index pregnancy). Data analyzed by multivariate analysis included the independent variables age, the number of early pregnancy losses before and after the last birth, respectively and a second trimester pregnancy loss before or after the last birth, respectively. The outcome variable was unexplained loss in the index pregnancy. In patients with secondary RPL, both a late and each early loss before the last birth did not significantly influence the risk of a new pregnancy loss in the index pregnancy: incidence rate ratio (IRR) 1.31 (95% CI 0.62-2.77) and IRR 0.88 (95% CI 0.70-1.11), respectively. In contrast, the impact on risk of pregnancy loss conferred by a late and by each early pregnancy loss occurring after the birth was significant: IRR 2

    Laterality in temporal lobe epilepsy is usually defined by EEG and imaging results. We investigated whether the analysis of seizure semiology including lateralizing seizure phenomena identifies bilateral independent temporal lobe seizure onset. We investigated the seizure semiology in 17 patients in whom invasive EEG-video-monitoring documented bilateral temporal seizure onset. The results were compared to 20 left and 20 right consecutive temporal lobe epilepsy (TLE) patients who were seizure free after anterior temporal lobe resection. The seizure semiology was analyzed using the semiological seizure classification with particular emphasis on the sequence of seizure phenomena over time and lateralizing seizure phenomena. Statistical analysis included chi-square test or Fisher's exact test. Bitemporal lobe epilepsy patients had more frequently different seizure semiology (100% vs. 40%; p<0.001) and significantly more often lateralizing seizure phenomena pointing to bilateral seizure onset compared to patients with unilateral TLE (67% vs. 11%; p<0.001). The sensitivity of identical vs. different seizure semiology for the identification of bilateral TLE was high (100%) with a specificity of 60%. Lateralizing seizure phenomena had a low sensitivity (59%) but a high specificity (89%). The combination of lateralizing seizure phenomena and different seizure semiology showed a high specificity (94%) but a low sensitivity (59%). The analysis of seizure semiology including lateralizing seizure phenomena adds important clinical information to identify patients with bilateral TLE. Copyright © 2014 Elsevier B.V.

    Purpose: The treatment of MG in old patients is controversial and not well established. Some authors consider that adjuvant radiotherapy (RT) is not useful to improve survival. Our aim was to identify which group of patients older than 65 years might benefit of adjuvant radiotherapy (RT). Patients and Methods: A total of 85 consecutive patients were analyzed from two Institutions diagnosed during the period 1987-1995. Forty six were male and 39 female. The median age was 70 (r 65-81). The extent of surgery (S) was analyzed by neurosurgeons reports or postoperative CT scan (32 p. underwent biopsy, 25 partial resection, 28 complete resection). Glioblastoma Multiforme was observed in 64 patients (75%) and anaplastic gliomas in 21 patients (25%). Postoperative Karnofsky Index (KI) was as follows: in 47 p 60% (for 2 p was unknown). Survival probability was estimated using Kaplan-Meier method and compared with log-rank test. Crude and adjusted hazard ratios (HR) were calculated using Cox's regression models. Results: Forty four patients were treated by adjuvant RT and 41 patients were not. Median survival time for all patients was 18.3 weeks. In multivariate analysis we found that the most powerful independent variable was not to receive RT with a hazard ratio of 8.5 (CI 4.55-16.06). Reasons for not RT were: in 7 p. postsurgical complications, in 17 p. KI 40%. Multivariate analysis showed that the most significant independent variable was age ( 71 y) with a HR of 2.85 (CI 1.31-6.19). Conclusions: 1- Patients who did not received RT, due to several reasons, had poorer evolution. 2-In patients who received adjuvant treatment, it was suggested that age is the first variable to consider, although patients older than 71 can benefit of RT (see table)

    Full Text Available Background : The association of intraspinal neural anomalies with scoliosis is known for more than six decades. However, there are no studies documenting the incidence of association of intraspinal anomalies in scoliotic patients in the Indian population. The guide lines to obtain an magnetic resonance imaging (MRI scan to rule out neuro-axial abnormalities in presumed adolescent idiopathic scoliosis are also not clear. We conducted a prospective study (a to document and analyze the incidence and types of intraspinal anomalies in different types of scoliosis in Indian patients. (b to identify clinico-radiological ′indicators′ that best predict the findings of neuro-axial abnormalities in patients with presumed adolescent idiopathic scoliosis, which will alert the physician to the possible presence of intraspinal anomalies and optimize the use of MRI in this sub group of patients. Materials and Methods : The data from 177 consecutive scoliotic patients aged less than 21 years were analyzed. Patients were categorized into three groups; Group A - congenital scoliosis (n=60, group B -presumed idiopathic scoliosis (n=94 and group C - scoliosis secondary to neurofibromatosis, neuromuscular and connective tissue disorders (n=23. The presence and type of anomaly in the MRI was correlated to patient symptoms, clinical signs and curve characteristics. Results : The incidence of intraspinal anomalies in congenital scoliosis was 35% (21/60, with tethered cord due to filum terminale being the commonest anomaly (10/21. Patients with multiple vertebral anomalies had the highest incidence (48% of neural anomalies and isolated hemi vertebrae had none. In presumed ′idiopathic′ scoliosis patients the incidence was higher (16% than previously reported. Arnold Chiari-I malformation (AC-I with syringomyelia was the most common neural anomaly (9/15 and the incidence was higher in the presence of neurological findings (100%, apical kyphosis (66.6% and early

  18. Hepatotoxicity in hyperthyroid patient after consecutive methimazole and propylthiouracil therapies

    Directory of Open Access Journals (Sweden)

    Fernando Gomez-Peralta

    2018-01-01

    Full Text Available Methimazole (MMI and propylthiouracil (PTU are widely used antithyroid drugs (ATD that have been approved for the treatment of hyperthyroidism. Hepatotoxicity may be induced by these drugs, though they exert dissimilar incidence rates of hepatotoxicity and, possibly, with different underlying pathogenic mechanisms. We report the case of a 55-year-old woman with no relevant medical history diagnosed with hyperthyroidism due to Graves’ disease, who developed two episodes of acute hepatitis concurrent with the consecutive administration of two different ATDs, first MMI and then PTU. Given the impossibility of administering ATDs, it was decided to perform a total thyroidectomy because the patient was found to be euthyroid at that point. Pathological anatomy showed diffuse hyperplasia and a papillary thyroid microcarcinoma of 2 mm in diameter. Subsequent clinical check-ups were normal. This case suggests the importance of regular monitoring of liver function for hyperthyroid patients. Due to the potential severity of this side effect, it is recommended to determine baseline liver function prior to initiation of treatment.

    Neuroblastoma is an aggressive pediatric tumor accounting for ~15% of cancer-associated mortalities in children. Despite the current intensive therapy, >50% of high-risk patients experience tumor relapse or regrowth caused by the activation of minimal residual disease (MRD). Although several MRD detection protocols using various reverse transcription-quantitative polymerase chain reaction (RT-qPCR) markers have been reported to evaluate the therapeutic response and disease status of neuroblastoma patients, their clinical significance remains elusive. The present study reports two high-risk neuroblastoma patients, whose MRD was consecutively monitored using 11 RT-qPCR markers (CHRNA3, CRMP1, DBH, DCX, DDC, GABRB3, GAP43, ISL1, KIF1A, PHOX2B and TH) during their course of treatment. The two patients initially responded to the induction therapy and reached MRD-negative status. The patients' MRD subsequently became positive with no elevation of their urinary homovanillic acid, urinary vanillylmandelic acid and serum neuron-specific enolase levels at 13 or 19 weeks prior to the clinical diagnosis of tumor relapse or regrowth. The present cases highlight the possibility of consecutive MRD monitoring using 11 markers to enable an early detection of tumor relapse or regrowth in high-risk neuroblastoma patients.

    Recently Oliver and Soundararajan made conjectures based on computational enumerations about the frequency of occurrence of pairs of last digits for consecutive primes. By studying Eratosthenes sieve, we have identified discrete dynamic systems that exactly model the populations of gaps across stages of Eratosthenes sieve. Our models provide some insight into the observed biases in the occurrences of last digits in consecutive primes, and the models suggest that the biases will ultimately be ...

  2. A consecutive series of patients with laryngeal carcinoma treated by primary irradiation

    In Denmark there is an increasing frequency of laryngeal carcinoma, in particular in women and among these especially in supraglottic tumours. The incidence during the past 20 years has risen from about 40 to 60 cases per million per year. A series of 335 consecutive patients treated with primary radiation is presented. In one-third of all patients the tumour was localized in the supraglottic area; in women in more than half and in men in about one-fourth of the cases. The frequency of primary lymph node metastases in the supraglottic and the glottic tumours was 24% and 2% respectively. A multivariate analysis identified sex and tumour size as independent prognostic parameters of local control. Five-year survival corrected for intercurrent deaths was obtained in 59% of all cases, in 56% of supraglottic and in 92% of glottic tumours. A multivariate analysis defined localization, tumour grade and stage as independent prognostic parameters of survival. Salvage surgery was performed in about 32% of the cases, total laryngectomy in 26%, and partial laryngectomy in 6%. The survival rate among all total laryngectomies was 55%. A tracheostomy during or before radiation treatment prior to total laryngectomy had no influence on complication rate, admission time or recurrence rate. The frequency of pharyngo-cutaneous fistulae in the entire series was 11.5%; after routine use of metronidazol, however, only 5.7%. Radical neck dissection was carried out in 7.8% of the cases, by far most in the supraglottic group, only a few in the glottic carcinomas, in three-fourth in connection with a laryngectomy and in one-fourth without local recurrence in the larynx.

Five-year survival corrected for intercurrent deaths was obtained in 59% of all cases, in 56% of supraglottic and in 92% of glottic tumours. A multivariate analysis defined localization, tumour grade and stage as independent prognostic parameters of survival. Salvage surgery was performed in about 32% of the cases, total laryngectomy in 26%, and partial laryngectomy in 6%. The survival rate among all total laryngectomies was 55%. A tracheostomy during or before radiation treatment prior to total laryngectomy had no influence on complication rate, admission time or recurrence rate. The frequency of pharyngo-cutaneous fistulae in the entire series was 11.5%; after routine use of metronidazol, however, only 5.7%. Radical neck dissection was carried out in 7.8% of the cases, by far most in the supraglottic group, only a few in the glottic carcinomas, in three-fourth in connection with a laryngectomy and in one-fourth without local recurrence in the larynx.

    Diabetes mellitus is a 21st century pandemic. Due to life-span prolongation combined with the increased rate of diabetes, a growing population of patients is afflicted with neuropathic foot deformities. Traditional operative repair of these deformities is associated with a high complication rate and relatively common infection incidence. In recent years, in order to prevent these complications, percutaneous deformity correction methods were developed. Description of experience accumulated in treating 20 consecutive patients with diabetic neuropathic foot deformities treated in a percutaneous fashion. A consecutive series of patients treated at our institute for neuropathic foot deformity was assessed according to a standard protocol using the AOFAS forefoot score and the LUMT score performed at baseline as well as at 6 months and 12 months. Treatment related complications were monitored. All procedures were performed in an ambulatory setting using local anesthesia. A total of 12 patients had soft tissue corrections, and 8 had a combined soft tissue and bone correction. Baseline AOFAS score was 48±7 and improved to 73±9 at six months and 75±7 at one year. LUMT score in 11 patients with a chronic wound decreased from 22±4 to 2±1 at one year post-op. One patient required hospitalization due to post-op bleeding. Percutaneous techniques allow deformity correction of diabetic feet, including those with open wounds in an ambulatory setting with a low complication rate.

    OBJECTIVE: The long-term survival of in-hospital cardiac arrest (IHCA) patients treated with targeted temperature management (TTM) is poorly described. The aim of this study was to compare the outcomes of consecutive IHCA with out-of-hospital cardiac arrest (OHCA) patients treated with TTM. DESIGN...... SETTING AND PATIENTS: Retrospectively collected data on all consecutive adult patients treated with TTM at a university tertiary heart center between 2005 and 2011 were analyzed. MEASUREMENTS: Primary endpoints were survival to hospital discharge and long-term survival. Secondary endpoint was neurological...... time to return of spontaneous circulation (ROSC). Survival to hospital discharge was 54% for OHCA and 53% for IHCA (adjusted odds ratio 0.98 [95% confidence interval {CI}; 0.43-2.24]). Age ≤60 years, bystander CPR, time to ROSC ≤10 min, and shockable rhythm at presentation were associated with survival...

    recognition of prevalent delirium and prediction of incident delirium may be difficult at first assessment. We therefore aimed to validate a pragmatic delirium susceptibility (for any, prevalent and incident delirium) score for use in front-line clinical practice in a consecutive cohort of older acute medicine patients. consecutive patients aged ≥65 years over two 8-week periods (2010-12) were screened prospectively for delirium using the Confusion Assessment Method (CAM), and delirium was diagnosed using the DSM IV criteria. The delirium susceptibility score was the sum of weighted risk factors derived using pooled data from UK-NICE guidelines: age >80 = 2, cognitive impairment (cognitive score below cut-off/dementia) = 2, severe illness (systemic inflammatory response syndrome) = 1, infection = 1, visual impairment = 1. Score reliability was determined by the area under the receiver operating curve (AUC). among 308 consecutive patients aged ≥65 years (mean age/SD = 81/8 years, 164 (54%) female), AUC was 0.78 (95% CI 0.71-0.84) for any delirium; 0.71 (0.64-0.79), for prevalent delirium; 0.81 (0.70-0.92), for incident delirium; odds ratios (ORs) for risk score 5-7 versus delirium, 8.1 (2.2-29.7), P = 0.002 for prevalent delirium, and 25.0 (3.0-208.9) P = 0.003 for incident delirium, with corresponding relative risks of 5.4, 4.7 and 13. Higher risk scores were associated with frailty markers, increased care needs and poor outcomes. the externally derived delirium susceptibility score reliably identified prevalent and incident delirium using clinical data routinely available at initial patient assessment and might therefore aid recognition of vulnerability in acute medical admissions early in the acute care pathway. © The Author 2016.

    AIM: To identify prognostic factors for long-term outcome for patients with hepatocellular carcinoma (HCC) after percutaneous microwave or radiofrequency ablation. MATERIALS AND METHODS: In total, 137 consecutive patients with HCC underwent microwave or radiofrequency ablation with curative intent; 16 possible prognostic factors were evaluated for their association with overall survival (OS) and disease-free survival (DFS) using univariate and multivariate analysis. RESULTS: The median OS and DFS were 27.0 months and 8.2 months, respectively. OS rates for all patients at 1, 2, 3, 4 and 5 years were 73.9%, 52.1%, 42.8%, 26.2% and 20.1%, respectively. DFS rates at 1, 2, 3 and 4 years were 38.1%, 21.9%, 18.8%, and 14.1%, respectively. Pretreatment serum alpha-fetoprotein (AFP) >200 ng/ml, pretreatment serum albumin {<=}35 g/dl, liver function Child's class C and incomplete ablation were found to be significant predictors for OS by univariate analysis. Using multivariate analysis, incomplete ablation was identified to be the most significant independent predictor for OS. Other independent predictors for OS were serum albumin level, serum AFP level and Child-Pugh classification. Recurrence after hepatectomy and prothrombin time >14 s were identified to be significant predictors for DFS by univariate analysis, and the former was the only independent predictor for DFS by multivariate analysis. CONCLUSION: Prognosis for patients with HCC after thermal ablation with curative intent was determined by treatment response to ablation, pretreatment serum AFP, and liver function reserve. Tumour response to treatment was the most predictive factor for long-term survival and was related to tumour size, thus careful selection of patients for ablation therapy is recommended.

    Full Text Available Maple syrup urine disease is caused by a deficiency in the branched chain ketoacid dehydrogenase (BCKAD complex. This results in the accumulation of branched chain amino acids (BCAA and branched chain ketoacids in the body. Even when aggressively treated with dietary restriction of BCAA, patients experience long term cognitive, neurological and psychosocial problems. Liver transplantation from deceased donors has been shown to be an effective modality in introducing adequate BCKAD activity, attaining a metabolic cure for patients. Here, we report the clinical course of the first known patient with classic MSUD who received two consecutive partial liver grafts from two different living non-carrier donors and his five year outcome posttransplant. We also show that despite the failure of the first liver graft, and initial acute cellular rejection of the second liver graft in our patient, his metabolic control remained good without metabolic decompensation.

    To investigate the incidence of and factors predisposing to consecutive esotropia after intermittent exotropia surgery, and to prevent the onset of consecutive esotropia. We retrospectively surveyed 226 patients who had been followed up for more than 1 year after surgery for intermittent exotropia conducted between February 2005 and September 2010. Consecutive esotropia was defined as an esotropia of at least 10 prism diopters (PD) at distance or near at least once in 2 weeks after surgery. Presumed risk factors for consecutive esotropia were analyzed. Gender, age at surgery, average binocular spherical equivalent, anisometropia, high myopia, amblyopia, preoperative angle of deviation, vertical deviation, A-V pattern strabismus, exotropia type, type of surgery, stereopsis, and suppression were investigated to evaluate factors influencing the onset of consecutive esotropia. Consecutive esotropia occurred in 22 patients (9.7 %). Significant correlations with occurrence of the condition were found with high myopia (P = 0.013), amblyopia (P = 0.047), preoperative angle of deviation of 25-40 PD at distance (P = 0.016), deviation at distance - deviation at near > 10 PD (P = 0.041), lateral incomitance (P = 0.007), tenacious proximal convergence fusion type (P = 0.001), unilateral lateral rectus muscle recession and medial rectus muscle resection (P = 0.001). High myopia, amblyopia, and lateral incomitance were predisposing factors for consecutive esotropia. Furthermore, the preoperative angle of deviation at distance, differences between the angle of deviation at near and at distance, the type of intermittent exotropia, and the type of surgery affected the incidence of consecutive esotropia. More attention must be paid to patients with such factors.

    Controversy persists regarding the optimal procedure to rejuvenate the aging neck. More invasive procedures carry increased risks of complications, whereas less invasive approaches may deliver marginal results. The challenge is selecting the appropriate procedure for delivering consistent, durable results meeting both the patient's and surgeon's expectations. The authors describe their trampoline platysmaplasty (TPP) approach, a percutaneous suture suspension necklift that constitutes a less invasive approach for neck rejuvenation. A retrospective study was conducted of 105 consecutive patients who underwent TPP. Age, sex, procedure(s) performed, complications, and patient satisfaction were recorded. Cadaver studies were conducted to compare the tensile strength of the ligaments that anchor the TPP to the tensile strength of the sutures placed to approximate the medial platysma borders. In addition, the accuracy of light transillumination to determine depth of travel of the light-emitting diode (LED) lighted rod was evaluated. Patients underwent either TPP alone (18 women, 24 men) or TPP with a facelift (35 women, 28 men) between October 2007 and June 2009. The average age of the patients was 52 years, and average length of follow-up was 33 months. Patient satisfaction was high. Three early patients underwent immediate revision to improve results secondary to the suture matrix being too loose. Six additional patients had recurrent banding around one year postoperatively, but correction was achieved in all six by replacing the matrix with the help of the lighted rod. The results of the cadaver study revealed that the tensile strength of the retaining ligaments was statistically identical to the medial platysma borders, and the light transillumination feedback was accurate with regard to the depth of travel of the illuminated rod tip. The TPP approach for neck rejuvenation is effective and durable in properly-selected patients. It works well as a stand

    The aim of this study was to evaluate the value of thyroglobulin (Tg) kinetics during preparation of radioiodine ablation for prediction of initial radioiodine ablation failure in thyroid cancer patients. Thyroid cancer patients after total thyroidectomy who underwent radioiodine ablation with 3–4 weeks of hormone withdrawal between May 2011 and January 2012 were included. Consecutive serum Tg levels 5–10 days before ablation (Tg1) and on the day of ablation (Tg2) were obtained. The difference between Tg1 and Tg2 (ΔTg), daily change rate of Tg (ΔTg/day) and Tg doubling time (Tg-DT) were calculated. Success of initial ablation was determined by the results of the follow-up ultrasonography, diagnostic radioiodine scan and stimulated Tg level after 6 to 20 months. A total of 143 patients were included. Failed ablation was reported in 52 patients. Tg2 higher than 5.6 ng/ml and Tg-DT shorter than 4.2 days were significantly related to a high risk of ablation failure. ΔTg and ΔTg/day did not show significant correlation with ablation failure. Thyroglobulin kinetics on consecutive blood sampling during hormone withdrawal may be helpful in predicting patients with higher risk of treatment failure of initial radioiodine ablation therapy in thyroid cancer patients.

    The metabolic evaluation of children with nephrolithiasis begins with a 24-h urine collection. For adults, the diagnostic yield increases with consecutive collections; however, little is known regarding the variability of multiple 24-h studies in the pediatric population. We sought to evaluate the variability of consecutive 24-h urine collection in children through a multi-institutional study hypothesizing that compared with a single collection, consecutive 24-h urine collections would reveal a greater degree of clinically useful information in the evaluation of children at risk for nephrolithiasis. Including data from six institutions, we identified children less than 18 years of age considered at risk for recurrent nephrolithiasis, undergoing metabolic evaluation. We evaluated a subset of patients performing two collections with urine creatinine varying by 10% or less during a 7-day period. Discordance between repeat collections based on normative urine chemistry values was evaluated. A total of 733 children met inclusion criteria, and in over a third both urine calcium and urine volume differed by 30% or more between samples. Urine oxalate demonstrated greater variation between collections in children collections prior to targeted intervention to modify stone risk are advised to increase diagnostic yield in children at risk for nephrolithiasis.

    Painless thyroiditis (PT) is a transient kind of thyrotoxicosis, with lack of uptake on a thyroid scintigraphy in a non-tender thyroid gland, elevated anti-TPO antibodies, no fever, no history of increased iodine intake, and a normal sedimentation rate. The prevalence of PT varies hugely in the literature. To establish the incidence rate of PT in Denmark as well as to describe the phenotype of PT in more detail. Tc-99m pertechnetate scintigraphies were performed over a period of 9.75 years on 6022 consecutive patients (2349 had a thyrotoxic episode), and were divided into high or normal (5528), reduced (300) or lack of uptake (194). Patient records were evaluated: 292 with reduced, and 186 with lack of uptake. As a control measure, 230 consecutive thyrotoxic patients were also analyzed. Based on scintigraphies, 12 patients had PT, 10 with lack of uptake and two with reduced, corresponding to an incidence rate of 0.49/100,000 person years. It was predicted, that only one patient among the newly diagnosed consecutive thyrotoxic cohort had PT. This patient was identified. The prevalence of PT among thyrotoxic patients was 0.51% as evaluated by scintigraphy, and 0.43% among the biochemically thyrotoxic patient cohort. Twenty-five percent had more than one thyrotoxic episode, 75% had at least one subsequent hypothyroid episode, and 33% developed permanent hypothyroidism. PT presenting with symptomatic thyrotoxicosis is an extremely rare disease in Denmark. Symptomatic PT presents most often with no uptake on a Tc-99m pertechnetate scintigraphy. Clinical follow-up is essential.

    To determine angiographically the origins and variations of renal arteries. The study included 855 consecutive patients (163 females, 692 males; mean age, 61 years) living in the Cukurova region of Turkey, who underwent either aortofemoropopliteal (AFP) angiography for the investigation of peripheral arterial disease, or renal angiography for renovascular hypertension, and were prospectively evaluated. Renal arteries were visualized by non-selective catheterization during AFP angiography and by selective or non-selective catheterization during renal angiography. Locations of renal artery origins and renal artery variations, including the presence of extra renal arteries and division patterns were analyzed on angiograms. The origin of main renal arteries off the aorta was between the upper margin of L1 and lower margin of L2 vertebra in 98% of the patients, and in 74%, this was the origin of extra renal arteries. The most common location for renal artery origin was the L1-L2 intervertebral disc level. A single renal artery was present in both kidneys in 76% of patients. Renal artery variations included multiple arteries in 24%, bilateral multiple arteries in 5%, and early division in 8% of the cases. Additional renal arteries on the right side were found in 16% and on the left side in 13% of cases. Of all the extra renal arteries, the percentage of accessory and aberrant renal arteries were 49% and 51%, respectively. Renal arteries originated between the first and the second lumbar vertebral levels in most patients. Extra renal arteries were quite frequent. These results should be kept in mind when a non-invasive diagnostic search is performed for renal artery stenosis, or when renal surgery related to renal arteries is performed.

    Allogeneic blood product use during cardiac operation is often reported to exceed 40% despite published guidelines and costly blood conservation strategies. We developed a predictive model, based on eight preoperative risk factors, of allogeneic blood product transfusion rates in patients undergoing a cardiac procedure. All 3,046 consecutive, isolated coronary artery bypass graft (CABG) procedures at a university hospital from 1995 to 1998 were included. A logistic regression model was created to identify independent predictors of allogeneic blood product transfusion. This model was validated using a prospective patient sample. Overall use of allogeneic blood products was 23% with a crude operative mortality of 2.1%. In isolated, elective, first-time CABG cases, 16.9% received allogeneic blood products. Independent predictors of blood product usage in CABG patients were preoperative hemoglobin 12.0 or less, emergent operation, renal failure, female sex, age 70 years or older, left ventricular ejection fraction 0.40 or less, redo procedure, and low body surface area. Prospective validation of this model on 2,117 consecutive isolated CABG patients demonstrated an observed-to-expected allogeneic blood product transfusion rate ratio of 1.06. This internally validated logistic regression risk model is a sensitive and specific predictor of allogeneic blood product use in patients undergoing isolated CABG. Utilization of this model allows for preoperative risk stratification and may allow for more rational resource allocation of costly blood conservation strategies and blood bank resources.

    Full Text Available Aim : We report the outcome analysis of retropubic radical prostatectomy (RRP performed in 428 patients in terms of pathological findings, complications, and survival. Materials and Methods : Systematically recorded case reports forms of consecutive 428 RRPs done over a 14-year period were analyzed using the SPSS 14 software. Secondary analysis was done to evaluate era specific (pre and post 2002 changes in clinical features and survivals. Results : Seven-year overall survival (OAS, cancer-specific survival (CSS, and event-free survival (EFS was 83.2%, 82.8%, and 69.8% respectively in our series. Era-specific survival showed higher CSS post 2002, and there was an increase in presentation with organ-confined disease. Univariate and multivariate analysis showed statistically significant impact on era specific outcome. With the improvement in techniques decrease in complications rate and increase in quality of life was noted. Conclusions : Our series spanning over decade demonstrates that RRP is viable option to offer cure to organ-confined carcinoma prostate. Further, there is evidence of stage migration and improvements in outcome in post 2002 patients. Although our series is modest in number, the success rates and outcome data matches those reported in the literature.

    Costs of percutaneous coronary interventions (PCI) have an important impact on health care expenditures. Despite the present stress upon the cost-effectiveness issues in medicine, few comprehensive data exist on costs and resource use in different clinical settings. To assess catheterisation laboratory costs related to use of drugs and single-use devices in patients undergoing PCI due to coronary artery disease. Retrospective analysis of 1500 consecutive PCIs (radial approach, n = 1103; femoral approach, n = 397) performed due to ST segment elevation myocardial infarction (STEMI; n = 345) and non ST-segment elevation myocardial infarction (NSTEMI; n = 426) as well as unstable angina (UA; n = 489) and stable angina (SA; n = 241) was undertaken. Comparative cost analysis was performed and shown in local currency units (PLN). The cath lab costs were higher in STEMI (4295.01 ± 2384.54PLN, p costs were positively correlated with X-ray dose, fluoroscopy, and total procedure times. Patients' age negatively correlated with cath lab costs in STEMI/NSTEMI patients. Cath lab costs were higher in STEMI patients compared to other groups. In STEMI/NSTEMI they were lower in older patients. In all analysed groups costs were related to the level of procedural difficulty. In female patients, the costs of PCI performed via radial approach were higher compared to femoral approach. Despite younger age, male patients underwent more expensive procedures.

    Background: The Absorb™ BVS is a bioresorbable, everolimus-eluting scaffold approved and marketed for coronary use. Published data on long-term results after treatment are limited to a small number of patients, most of them with elective PCI of simple lesions. The importance of scaffold resorption is variably appreciated among cardiologists, and indications for use from health technology assessment bodies or guidelines are missing. Instruments are needed to collect, share and assess the experience being accumulated with this new device in several centres. Methods/Design: The BVS-RAI Registry is a spontaneous initiative of a group of Italian interventional cardiologists in cooperation with Centro di Ricerche Farmacologiche e Biomediche 'Mario Negri' Institute, and is not recipient of funding or benefits originating from the BVS manufacturer. It is a prospective registry with 5-year follow-up of all consecutive patients who have undergone successful implantation of 1 or more coronary BVS following the indications, techniques and protocols used in each of the participating institutions. Outcome measures are BVS target lesion failure within one year and device-oriented major adverse cardiac events within 5 years. The registry started in October 2012 and will extend enrolment throughout 2015, with the aim to include about 1000 patients. ClinicalTrials.gov identifier is CT02298413. Conclusions: The BVS-RAI Registry will contribute observational knowledge on the long-term safety and efficacy of the Absorb™ BVS as used in a number of Italian interventional centres in a broad spectrum of settings. Unrewarded and undirected consecutive patient enrolments are key-features of this observation, which is therefore likely to reflect common clinical practice in those centres. - Highlights: • prospective data collection of successful Absorb implantation; • expert Italian centers; • no restrictions for enrollment/no exclusion criteria; • clinical follow up;

    In contrast to patent foramen ovale that is highly prevalent in the general population, atrial septal defect (ASD) is a rare congenital heart defect. The effect of ASD closure on headache and migraine remains a matter of controversy. The objectives of our study were (1) to determine headache prevalence in consecutive patients with ASD scheduled for percutaneous closure for cardiologic indications, using the International Classification of Headache Disorders and (2) to compare headache characteristics before and after closure of ASD. In this observational case series no a priori power analysis was performed. Twenty-five consecutive patients were prospectively included over 27 months. Median duration of follow-up was 12 months [interquartile range 0]. Prevalence of active headache seemed to be higher compared with the general population: any headaches 88% (95% confidence interval 70-96), migraine without aura 28% (14-48), migraine with aura 16% (6-35). After ASD closure, we observed a slightly lower headache frequency (median frequency 1.0 [2.6] vs. 0.3 [1.5] headaches per month; P = .067). In patients with ongoing headaches, a significant decrease in headache intensity (median VAS 7 [3] vs. 5 [4]; P = .036) was reported. Three patients reporting migraine with aura before the intervention noted no migraine with aura attacks at follow-up, 2 of them reported ongoing tension-type headache, 1 migraine without aura. In summary, this prospective observational study confirms the high prevalence of headache, particularly migraine, in ASD patients and suggests a possible small beneficial effect of ASD closure. © 2011 American Headache Society.

    Tibiofemoral contact kinematics or knee implant motions have a direct influence on patient function and implant longevity and should be evaluated for any new alignment technique such as kinematically aligned total knee arthroplasty (TKA). Edge loading of the tibial liner and external rotation (reverse of normal) and adduction of the tibial component on the femoral component are undesirable contact kinematics that should be minimized. Accordingly, this study determined whether the overall prevalence of undesirable contact kinematics during standing, mid kneeling near 90 degrees and full kneeling with kinematically aligned TKA are minimal and not different between groups of consecutive patients treated by different surgeons. Three surgeons were asked to perform cemented, kinematically aligned TKA with patient-specific guides in a consecutive series of patients with their preferred cruciate-retaining (CR) implant. In vivo tibiofemoral contact positions were obtained using a 3- to 2-dimensional image registration technique in 69 subjects (Vanguard CR-TKA N = 22, and Triathlon CR-TKA N = 47). Anterior or posterior edge loading of the tibial liner was not observed. The overall prevalence of external rotation of the tibial component on the femoral component of 6 % was low and not different between surgeons (n.s.). The overall prevalence of adduction of the tibial component on the femoral component of 4 % was low and not different between surgeons (n.s.). Kinematically aligned TKA minimized the undesirable contact kinematics of edge loading of the tibial liner, and external rotation and adduction of the tibial component on the femoral component during standing and kneeling, which suggests an optimistic prognosis for durable long-term function.

    The laparoscopic Heller-Dor operation has been the procedure of choice for the treatment of achalasia. However, because the incidence of achalasia is low, reports on the outcome of surgical treatment for achalasia are limited. In this study, the therapeutic results after laparoscopic Heller-Dor operation for achalasia at a single university hospital were evaluated. Between August 1994 and July 2006, 100 consecutive patients underwent laparoscopic Heller-Dor operation. The therapeutic results after laparoscopic Heller-Dor operation were assessed based on complications, operation time, blood loss, postoperative hospital stay, and the standardized questionnaire for satisfaction by telephone or outpatient clinic interview. With respect to perioperative complications, lower esophageal mucosal perforation occurred in 14 patients, but all of them could be suture-obliterated laparoscopically. One patient was converted to laparotomy because of uncontrolled bleeding from the short gastric artery. The mean operative time was 169 minutes, and the mean perioperative blood loss was 22 mL. The median postoperative hospital stay was 7 days. Reflux esophagitis, which was seen in five patients, was treated successfully with a proton pump inhibitor. According to the standardized questionnaire for satisfaction, 77 patients rated their recovery as 'excellent', 17 as 'good', 4 as 'fair', and 2 as 'poor'; thus, the overall success rate was 94%. There were no significant differences in surgical outcomes by morphologic type and severity of esophageal dilatation; however, the success rate deteriorated significantly with progression of the morphologic type. Laparoscopic Heller-Dor operation is a safe and effective surgical treatment for achalasia.

    The impact of patient-prosthesis mismatch (PPM) after aortic valve replacement (AVR) on short-term and long-term mortality remains controversial. The objective of this study was to evaluate the incidence and severity of PPM and its impact on short-term survival in a large cohort of patients treated with isolated stented biological AVR in a single institution. We analyzed retrospectively data of 632 consecutive patients with aortic stenosis undergoing isolated stented biological AVR between January 2007 and February 2012 at our institution. PPM was defined as an indexed effective orifice area ≤ 0.85 cm(2)/m(2). Statistical analyses were performed to identify influencing variables on valve size implanted. Of the 632 patients investigated, 46% were females and mean age was 71.9 ± 10.4 years. PPM was observed in 93.8% (593 of 632 patients). In 71% of the patients, moderate (0.65-0.85 cm(2)/m(2)) PPM was present and in 22.8% severe (body mass index, and body surface area as simultaneous predictors of the valve size implanted (R(2)= 0.39). PPM had no discernable impact on short-term survival, although it was present in 93.8% of our patients following isolated stented biological AVR. Georg Thieme Verlag KG Stuttgart · New York.

    This study investigated the reasons for some patients requiring two consecutive sessions of percutaneous radiofrequency (RF) ablation of hepatocellular carcinoma (HCC). We reviewed our database of 1,179 patients (1,624 treatments) with HCCs treated by percutaneous ultrasound (US)-guided RF ablation over 6 years. We retrospectively evaluated 80 patients who required a second session after the first session. The medical records and follow-up CTs were studied. We assessed the reasons for the second session and the patient outcomes. A second session was required in 80 (4.8%) out of 1,642 treatments of percutaneous RF ablation for HCC. The reason for the second session included technical failure related to the patient or the procedure (n=26), technical failure due to residual (n=40), newly detected (n=11) or missed (n=3) tumors found at the immediate follow-up CT. All patients were retreated with a second RFA session the next day. Seventy-five (93%) of 80 patients achieved complete ablation after the second session. The remaining five patients were treated by TACE (n=1), additional RFA (as second treatment at next admission) (n=3), or were lost to follow-up (n=1). After 1 month follow-up, 72 patients (96%) showed complete ablation after the second session. The interventional oncologist should understand the technical reasons for a patient requiring a second session of RF ablation when providing treatment for HCCs and perform careful pre-procedural planning to minimize the need for multi-session procedures.

    Full Text Available Objective: to report the group's experience with a series of patients undergoing pancreatic resection presenting null mortality rates. Methods: we prospectively studied 50 consecutive patients undergoing pancreatic resections for peri-ampullary or pancreatic diseases. Main local complications were defined according to international criteria. In-hospital mortality was defined as death occurring in the first 90 postoperative days. Results: patients' age ranged between 16 and 90 years (average: 53.3. We found anemia (Hb < 12g/dl and preoperative jaundice in 38% and 40% of cases, respectively. Most patients presented with peri-ampullary tumors (66%. The most common surgical procedure was the Kausch - Whipple operation (70%. Six patients (12% needed to undergo resection of a segment of the mesenteric-portal axis. The mean operative time was 445.1 minutes. Twenty two patients (44% showed no clinical complications and presented mean hospital stay of 10.3 days. The most frequent complications were pancreatic fistula (56%, delayed gastric emptying (17.1% and bleeding (16%. Conclusion : within the last three decades, pancreatic resection is still considered a challenge, especially outside large specialized centers. Nevertheless, even in our country (Brazil, teams seasoned in such procedure can reach low mortality rates.

    Mortality in patients with type 2 diabetes and diabetic foot osteomyelitis (DFO) have been explored in few small studies with a short follow-up. Aim of the present study is to assess all-cause and cardiovascular mortality and predictors of mortality in a consecutive series of patients with DFO. Patients with a diagnosis of DFO, attending the Diabetic Foot Unit of San Donato Hospital in Arezzo between January 1st, 2012 and December 31st, 2013, were included in this retrospective study. Information on all-cause mortality up to December 1st, 2016, was obtained from the registry of the Local Health Unit of Arezzo, which contains updated records of all persons living in Tuscany. One hundred ninety-four patients were included in the study. During a mean period of observation of 2.8±1.4years, 73 (37.6%) died, with a yearly rate of 13.2%. Of the 73 deaths, 59 were attributable to cardiovascular causes. After adjusting for possible confounders in a Cox analysis, site of osteomyelitis (hindfoot vs mid/forefoot) was associated with a higher mortality, and surgical treatment with a lower mortality. Mortality in patients with DFO appears to be much higher than that reported in clinical series of patients with diabetic foot ulcers, particularly when hindfoot is affected. Copyright © 2017.

    The purpose of this study was to evaluate the outcome of primary treatment and treatment of recurrences in patients with nasopharyngeal carcinoma. The material included 149 consecutive patients seen at the Aarhus University Hospital from 1963 to 1991 (49 females and 100 males). The stage distribution was: Stage I -9%, II-3%, III-28%, and IV-60%. Primary treatment was delivered with curative intent in 145 patients (97%). Persistent or recurrent disease after primary radical treatment was observed in 82 of the patients; 54% at the T-level, 40% at the N-level, and 33% at the M-level. A curative salvage attempt was carried out in 14 patients only, all with nodal recurrence: surgery in 8 patients (4 controlled) and radiotherapy in 6 patients (2 controlled). The 5-year local tumour control, locoregional tumour control, disease-specific survival rate and the overall survival rate for the patients treated with curative intent were 66%, 53%, 50% and 43%, respectively. Most of the patients (88%) had poorly differentiated tumours and these patients had the best prognosis. A major complication in three patients was radiation-induced myelopathy due to high-dose radiation delivered to the brain stem. Significant positive prognostic factors for treatment outcome in univariate analyses were early T-classification, small clinical stage, poor differentiation and low age. The Cox multivariate analysis showed that early T-categories, low N-categories and poor differentiation were independent, positive prognostic factors. Nasopharyngeal carcinoma is curable with primary radiotherapy; patients with poorly differentiated tumours have the best prognosis. Only a few patients were salvaged after recurrence. The factor most essential for success is primary control of the disease at the T- and N-levels

    Assessment of the oral health-related quality of life and the modulating factors of patients demanding dental treatment in the city of Salamanca, through the use of two validated instruments: the OIDP-sp (Oral Impacts on Daily Performance) and OHIP-14 (Oral Health Impact Profile). the study was conducted on a consecutive sample of 200 patients aged 18-65 years visiting an Integral Dental Centre in the city of Salamanca. Two validated instruments (OIDP-sp and OHIP-14) were used to measure the oral health-related quality of life. An analogue visual scale was used to register oral satisfaction. Data on sociodemographic background, behavioural and clinical factors were also gathered. ANOVA, T Student Test, and both Pearson and Spearman correlations coefficients were used for the statistical analysis. according to the OIDP, 68.5% suffered from some kind of impact in their oral quality of life, while impact prevalence with the OHIP was 85%. Some other factors influencing the quality of life and degree of satisfaction were revealed. patients over 45 years, regardless of their gender, from high social class, living in rural areas and with poor hygiene, showed higher impact and lower satisfaction. The study also revealed some clinical conditions closely related to the level of satisfaction.

    Dysphagia is a symptom suggestive of severe underlying pathology, although its causes include organic and non-organic disorders. The epidemiology of dysphagia is, however, poorly understood. We evaluated the prevalence of dysphagia in outpatients in Japan, measured the proportion ultimately found to have an organic cause, and recorded the nature of their symptoms and the underlying disorder. Of 5362 consecutive outpatients attending the Digestive Center at our hospital between June 1, 2010 and December 31, 2012, 186 patients (3.5 %) had dysphagia with a frequency score of ≥5 out of 6. The most common diagnosis was cancer (34 patients, 18.3 %), followed by gastroesophageal reflux disease (24 patients, 12.9 %). An esophageal motility disorder was diagnosed in 21 patients (11.3 %); the causes in the remaining 107 patients (57.5 %) were miscellaneous. Multivariable analysis identified the following predictors of cancer: age ≥ 54 years, weight loss, being a drinker of alcohol, and ≤2 gastrointestinal symptoms. Our findings can be used to inform the prioritization of referrals from primary care for investigation and treatment for patients with cancer for dysphagia.

    Attempted suicide is a major public health problem. The aim of this study was to identify patient-identified problems and triggers typically leading to attempted suicide. A representative sample of 66 adult patients was recruited from all clinical sites and psychiatrists who treat patients after attempted suicide in the Canton of Basel-City (Switzerland). Patients were diagnosed using the Structured Clinical Interview for DSM-IV (SCID) and interviewed with a local adaptation of the Explanatory Model Interview Catalogue (EMIC) to study underlying problems and triggers of attempted suicide. Of the patients, 92.4% had at least one DSM-IV disorder, with depressive disorders being the most prevalent disorder. Although half (50.0%) of the patients identified a health problem, 71.2% identified an interpersonal conflict as underlying problem leading to the suicide attempt. Furthermore, an interpersonal conflict was identified as the trigger of the suicide attempt by more than half of the patients (54.5%). The study included German-speaking patients only. According to patients, interpersonal problems often amplify underlying psychiatric problems, leading to suicide attempts. Social and interpersonal stressors should be acknowledged with integrated clinical and social interventions to prevent suicidal behavior in patients and populations.

    The simultaneous laparoendoscopic "rendezvous" (LERV) represents an alternative to sequential or totally laparoscopic approaches for patients affected by cholecystocholedocholithiasis. The aim of this study was to analyze the results in a large series of 210 consecutive patients. From 2002 to 2016 all patients affected by cholecystocholedocholithiasis were treated with a standardized "tailored" LERV. The relevant technical features of the procedure were recorded. An analysis of feasibility, effectiveness in stone clearance, and safety was performed. Among 214 patients with common bile duct stones, 210 were treated with LERV and 4 with open rendezvous approach. Intraoperative cholangiography confirmed common bile duct stones in 179 patients (85.2%) or sludge in 18 (8.5%) and in 98.9% stone clearance was obtained endoscopically. Endoscopic papilla cannulation was feasible in 161 patients (76.7%), whereas in 49 (23.3%) a transcystic guidewire was needed. The overall LERV feasibility was 96.6%. The conversion rate to open surgery was 3.3%. Minor morbidity was observed in 1.9% of cases, mortality in 0.47%, and the mean hospital stay was 4.3 days. These results confirm the high effectiveness of LERV. This approach to treat cholecystocholedocholithiasis should be preferred and therefore implemented where a strong collaboration between surgeons and endoscopists is possible.

    Purpose: The present study was performed to analyze the midterm results (five consecutive patients, 2-year follow-up) of the endovascular management of visceral artery aneurysms using the Cardiatis Multilayer Flow Modulator (CMFM) (Cardiatis, Isnes, Belgium), a self-expandable stent. Materials and Methods: From August 2009 to January 2011, we implanted five CMFMs in five patients (all men; mean age 73 years) to treat two common hepatic artery aneurysms, one celiac trunk aneurysm, one splenic artery aneurysm, and one superior mesenteric artery aneurysm (diameter 25-81 mm). The primary end point was technical success. The secondary end point was stent patency, absence of aneurysm rupture or reperfusion, and shrinking of the sac at 6-, 12-, and 24-month follow-up using computed tomography angiography. Follow-up ranged from 24 to 48 months (mean 31.2). Results: Technical success was achieved in all patients. Complete exclusion of the aneurysm with sac shrinking was achieved in two patients. Two stents became occluded at 6- and 24-month follow-up, respectively; both patients were asymptomatic and were not retreated. One patient developed sac reperfusion due to incomplete aneurysm exclusion. Conclusion: Long-term results in a wider population are needed to validate the effectiveness of the CMFM.

    Full Text Available Purpose: To evaluate the efficiency of medial rectus advancement surgery in consecutive exotropia. Material and Methods: The study group consisted of 20 cases, 10 male, 10 female, who were diagnosed as consecutive exotropia and underwent surgery between 2008-2013 at Cukurova University Medical Faculty Ophthalmology Department. Records of the patients were investigated retrospectively. We evaluated best corrected visual acuity, existence of ambliopia, postoperative duration following the first surgery and applied surgical procedures. Postoperative deviation lower than 10 PD were assesed as successful. Mean follow up period was 29,8 +/- 21,36 (8-80 months, patients with inadequate follow up period were dismissed from the study group. Results: We only applied bilateral medial rectus advancement surgery to 6 and unilateral medial rectus advancement surgery to 5 patients and obtained intended surgical result in these 11 cases. The other patients underwent lateral rectus recession or/and medial rectus resection operations inorder to reach projected deviation degrees. Deviation was found to be 46,4+/-9,24 (40-70 PD in cases who only underwent advancement surgery and was 65,56 +/- 18,78 (40-90 PD in cases who underwent additional surgical procedure. 16 (%80 of the cases had hypermetropi various dioptries and 7 (%35 had ambliopia. Discussion: Consecutive exotropia can appear years after surgery and is an important late period complication. In this study achievement of %55 success with medial rectus advancement surgery indicates that this is a preferable procedure. But in wide angle deviations additional lateral rectus recession or/and medial rectus resection operations can be applied inorder to reach intended adjustment. Accurrate prediction of the propotion of advancement surgery and adjustment is not always possible because of intensive fybrosis in operated muscles and enviroment tissue.

The AE patient cohort consists of 106 patients with AE of the liver of which 13 presented with cholestasis. 6/13 received bilio-digestive anastomosis and 7/13 patients were treated by ERC and are reported here. Biliary stricture balloon dilation was performed with 18-Fr balloons at the initial and with 24-Fr balloons at subsequent interventions. If indicated 10 Fr plastic stents were placed.Six patients were treated by repeated balloon dilation and stenting, one by stenting only. After an acute phase of 6 months with repeated balloon dilation, three patients showed "sustained clinical success" and four patients "assisted therapeutic success," of which one has not yet reached the six month endpoint. In one patient, sustained success could not be achieved despite repeated insertion of plastic stents and balloon dilation, but with temporary insertion of a fully covered self-expanding metal stent (FCSEMS. There was no loss to follow up. No major complications were observed.Serial endoscopic dilation is a standard tool in the treatment of benign biliary strictures. Serial endoscopic intervention with balloon dilation combined with benzimidazole treatment can re-establish and maintain biliary duct patency in AE associated pathology and probably contributes to avoid or postpone bilio-digestive anastomosis. This approach is in accordance with current ERC guidelines and is minimally disruptive

Retrospective case series of seven consecutive patients with AE-associated biliary pathology and ERC treatment in an interdisciplinary endoscopy unit at a University Hospital which hosts a national echinococcosis treatment center. The AE patient cohort consists of 106 patients with AE of the liver of which 13 presented with cholestasis. 6/13 received bilio-digestive anastomosis and 7/13 patients were treated by ERC and are reported here. Biliary stricture balloon dilation was performed with 18-Fr balloons at the initial and with 24-Fr balloons at subsequent interventions. If indicated 10 Fr plastic stents were placed. Six patients were treated by repeated balloon dilation and stenting, one by stenting only. After an acute phase of 6 months with repeated balloon dilation, three patients showed "sustained clinical success" and four patients "assisted therapeutic success," of which one has not yet reached the six month endpoint. In one patient, sustained success could not be achieved despite repeated insertion of plastic stents and balloon dilation, but with temporary insertion of a fully covered self-expanding metal stent (FCSEMS). There was no loss to follow up. No major complications were observed. Serial endoscopic dilation is a standard tool in the treatment of benign biliary strictures. Serial endoscopic intervention with balloon dilation combined with benzimidazole treatment can re-establish and maintain biliary duct patency in AE associated pathology and probably contributes to avoid or postpone bilio-digestive anastomosis. This approach is in accordance with current ERC guidelines and is minimally disruptive for patients.

    Microvolt T-wave alternans (MTWA) has been found to predict fatal events in patients with coronary artery disease (CAD). In a previous study, we found that MTWA values are higher in patients with CAD, compared with apparently healthy individuals. In this study, we assessed the relation between CAD and MTWA in patients with a diagnosis based on coronary angiography results. We studied 98 consecutive patients undergoing coronary angiography for suspected CAD. All patients underwent a maximal exercise stress test (EST), and MTWA was measured in the precordial ECG leads. Patients were divided into three groups: 40 patients without any significant (>50%) stenosis (group 1); 47 patients with significant stenosis (group 2); and 11 patients with a previous percutaneous coronary intervention (PCI) who had no evidence of restenosis (group 3). EST was repeated after 1 month in 24 group 2 patients who underwent PCI and in 17 group 1 patients. MTWA was significantly higher in group 2 (58.7 ± 24 μV) compared with group 1 (34.2  ± 15 μV, P < 0.01) and group 3 (43.2 ± 24 μV, P < 0.05). An MTWA greater than 60 μV had 95% specificity and 82% positive predictive value for obstructive CAD. At 1-month follow-up, MTWA decreased significantly in patients treated with PCI (from 61.3 ± 22 to 43.5 ± 17 μV; P < 0.001), but not in group 1 patients (from 50.5 ± 22 to 44.3 ± 19 μV, P = 0.19). MTWA is increased in patients with obstructive CAD and is reduced by coronary revascularization. An assessment of MTWA can be helpful in identifying which patients with suspected CAD are likely to show obstructive CAD on angiography.

    The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    This study represents the first reported outcomes for patients with advanced ovarian cancer (AOC) in South-West Wales undergoing treatment with primary debulking surgery or primary chemotherapy respectively. This is a retrospective study of consecutive, unselected patients with advanced ovarian, fallopian tube or primary peritoneal cancer (FIGO III/IV) presenting to a regional cancer centre between October 2007 and October 2014. Patients were identified from Welsh Cancer Services records and relevant data was extracted from electronic National Health Service (NHS) databases. Main outcome measures were median overall survival (OS), progression free survival (PFS) and perioperative adverse events. Hazard ratio estimation was carried out with Cox Regression analysis and survival determined by Kaplan-Meier plots. Of 220 women with AOC, 32.3% underwent primary debulking surgery (PDS) and 67.7% primary chemotherapy and interval debulking (PCT-IDS). Patients were often elderly (median age 67 years) with a poor performance status (26.5% PS >1). Complete cytoreduction (0cm residual) was achieved in 32.4% of patients in the PDS group and in 50.0% of patients undergoing IDS. Median OS for all patients was 21.9 months (PDS: 27.0 and PCT-IDS: 19.2 months; p >0.05) and median PFS was 13.1 months (PDS: 14.3 months and PCT-IDS: 13.0 months; p >0.05). Median overall and progression free survival for patients achieving complete cytoreduction were 48.0 and 23.2 months respectively in the PDS group and 35.4 months and 18.6 months in the IDS group (p >0.05). This retrospective study of an unselected, consecutive cohort of women with AOC in South West Wales shows comparable survival outcomes with recently published trials, despite the relatively advanced age and poor performance status of our patient cohort. Over the seven-year study period, our data also demonstrated a non-significant trend towards improved survival following primary surgery in patients who achieved maximal

    High-risk patients with stage II colon cancer may benefit from adjuvant chemotherapy, but identifying this patient population can be difficult. We assessed the prognosis value for predicting tumor progression in patients with stage II colon cancer, of a panel of 2 biomarkers for colon cancer: tumor budding and preoperative carcinoembryonic antigen (CEA). Consecutive patients (N = 134) with stage II colon cancer who underwent curative surgery from 2000 to 2007 were included. Multivariate analysis was used to evaluate the association of CEA and tumor budding grade with 5-year disease-free survival (DFS). The prognostic accuracy of CEA, tumor budding grade and the combination of both (CEA-budding panel) was determined. The study found that both CEA and tumor budding grade were associated with 5-year DFS. The prognostic accuracy for disease progression was higher for the CEA-budding panel (82.1%) than either CEA (70.9%) or tumor budding grade (72.4%) alone. The findings indicate that the combination of CEA levels and tumor budding grade has greater prognostic value for identifying patients with stage II colon cancer who are at high-risk for disease progression, than either marker alone.

    Objective : Cleft surgeons often show 10 consecutive lip repairs to reduce presentation bias, however the validity remains unknown. The purpose of this study is to determine the number of consecutive cases that represent average outcomes. Secondary objectives are to determine if outcomes correlate with cleft severity and to calculate interrater reliability. Design : Consecutive preoperative and 2-year postoperative photographs of the unilateral cleft lip-nose complex were randomized and evaluated by cleft surgeons. Parametric analysis was performed according to chronologic, consecutive order. The mean standard deviation over all raters enabled calculation of expected 95% confidence intervals around a mean tested for various sample sizes. Setting : Meeting of the American Cleft Palate-Craniofacial Association in 2009. Patients, Participants : Ten senior cleft surgeons evaluated 39 consecutive lip repairs. Main Outcome Measures : Preoperative severity and postoperative outcomes were evaluated using descriptive and quantitative scales. Results : Intraclass correlation coefficients for cleft severity and postoperative evaluations were 0.65 and 0.21, respectively. Outcomes did not correlate with cleft severity (P  =  .28). Calculations for 10 consecutive cases demonstrated wide 95% confidence intervals, spanning two points on both postoperative grading scales. Ninety-five percent confidence intervals narrowed within one qualitative grade (±0.30) and one point (±0.50) on the 10-point scale for 27 consecutive cases. Conclusions : Larger numbers of consecutive cases (n > 27) are increasingly representative of average results, but less practical in presentation format. Ten consecutive cases lack statistical support. Cleft surgeons showed low interrater reliability for postoperative assessments, which may reflect personal bias when evaluating another surgeon's results.

    Full Text Available BackgroundBone and soft tissue sarcomas are commonly treated with consecutive-day chemotherapy regimens consisting of multiple anticancer agents. Chemotherapy-induced nausea and vomiting (CINV is a serious adverse effect of these regimens and may result in decreased energy intake during chemotherapy. Decreased energy intake may lead to undernutrition and may cause adverse effects on patient quality of life and survival.MethodsPatients with bone and soft tissue sarcomas who received consecutive-day chemotherapy were retrospectively evaluated. CINV and dietary energy intake were assessed, as well as the occurrences of hiccups and constipation during chemotherapy.ResultsA total of 13 patients, 10 males and 3 females, with a total 16 chemotherapy courses were included in the study. All patients received antiemetic prophylaxis. The CINV control rate, defined as no emesis and no rescue therapy, gradually decreased from chemotherapy day 1 (94% to day 5 (75%. Four patients experienced emesis, two of whom had been treated with a cisplatin-containing regimen. Decreased dietary energy intake was possibly associated with CINV during chemotherapy. Anorexia was grade 2 except for one case of grade 3. The incidences of hiccups and constipation were high on days 3–5.ConclusionAntiemetic prophylaxis treatment did not prevent emesis due to consecutive-day chemotherapy, especially with cisplatin-containing regimens, in patients with bone and soft-tissue tumors. Dietary energy intake decreased during chemotherapy, and this appeared to be associated with CINV. In addition, the incidence of hiccups and constipation increased during the course of consecutive-day chemotherapy regimens. Although these results are based on a small number of patients, it may be important to observe nutritional status during chemotherapy, as this may reflect a patient’s general condition. Nutritional counseling might be useful in supporting nutritional status in patients undergoing

    Full Text Available Epidemiological studies of neuromyelitis optica (NMO in Jamaica are lacking. Here we reviewed the clinical records of 700 patients undergoing neurological evaluation at the Kingston Public Hospital, the largest tertiary institution in Jamaica over a 4 month period. We investigated the diagnostic utility of Aquaporin-4 ImmuneglobulinG (AQP4-IgG testing in 36 consecutive patients with a diagnosis of an inflammatory demyelinating disorder (IDD of the central nervous system (CNS. Patients were classified into 3 categories: i NMO, n=10; ii multiple sclerosis (MS, n=14 and iii unclassified IDD (n=12. All sera were tested for AQP-IgG status by cell binding assay (Euroimmun. No MS cases were positive. Ninety per cent of NMO cases were positive. Four of 12 patients with unclassified IDD tested positive for AQP4-IgG. AQP4-IgG seropositivity was associated with a lower socioeconomic status, higher EDSS (P=0.04 and lower pulmonary function than the seronegative cases (P=0.007. Aquaporin-4 autoimmunity may account for a significant proportion of Jamaican CNS IDDs.

    To describe the clinical phenotype of idiopathic rapid eye movement (REM) sleep behavior disorder (IRBD) at presentation in a sleep center. Clinical history review of 203 consecutive patients with IRBD identified between 1990 and 2014. IRBD was diagnosed by clinical history plus video-polysomnographic demonstration of REM sleep with increased electromyographic activity linked to abnormal behaviors. Patients were 80% men with median age at IRBD diagnosis of 68 y (range, 50-85 y). In addition to the already known clinical picture of IRBD, other important features were apparent: 44% of the patients were not aware of their dream-enactment behaviors and 70% reported good sleep quality. In most of these cases bed partners were essential to convince patients to seek medical help. In 11% IRBD was elicited only after specific questioning when patients consulted for other reasons. Seven percent did not recall unpleasant dreams. Leaving the bed occurred occasionally in 24% of subjects in whom dementia with Lewy bodies often developed eventually. For the correct diagnosis of IRBD, video-polysomnography had to be repeated in 16% because of insufficient REM sleep or electromyographic artifacts from coexistent apneas. Some subjects with comorbid obstructive sleep apnea reported partial improvement of RBD symptoms following continuous positive airway pressure therapy. Lack of therapy with clonazepam resulted in an increased risk of sleep related injuries. Synucleinopathy was frequently diagnosed, even in patients with mild severity or uncommon IRBD presentations (e.g., patients who reported sleeping well, onset triggered by a life event, nocturnal ambulation) indicating that the development of a neurodegenerative disease is independent of the clinical presentation of IRBD. We report the largest IRBD cohort observed in a single center to date and highlight frequent features that were not reported or not sufficiently emphasized in previous publications.

    Background and Aims Biliary vessel pathology due to alveolar echicococcosis (AE) results in variable combinations of stenosis, necrosis and inflammation. Modern management strategies for patients with cholestasis are desperately needed. The aim is proof of principle of serial ERC (endoscopic retrograde cholangiography) balloon dilation for AE biliary pathology. Methods Retrospective case series of seven consecutive patients with AE-associated biliary pathology and ERC treatment in an interdisciplinary endoscopy unit at a University Hospital which hosts a national echinococcosis treatment center. The AE patient cohort consists of 106 patients with AE of the liver of which 13 presented with cholestasis. 6/13 received bilio-digestive anastomosis and 7/13 patients were treated by ERC and are reported here. Biliary stricture balloon dilation was performed with 18-Fr balloons at the initial and with 24-Fr balloons at subsequent interventions. If indicated 10 Fr plastic stents were placed. Results Six patients were treated by repeated balloon dilation and stenting, one by stenting only. After an acute phase of 6 months with repeated balloon dilation, three patients showed “sustained clinical success” and four patients “assisted therapeutic success,” of which one has not yet reached the six month endpoint. In one patient, sustained success could not be achieved despite repeated insertion of plastic stents and balloon dilation, but with temporary insertion of a fully covered self-expanding metal stent (FCSEMS). There was no loss to follow up. No major complications were observed. Conclusions Serial endoscopic dilation is a standard tool in the treatment of benign biliary strictures. Serial endoscopic intervention with balloon dilation combined with benzimidazole treatment can re-establish and maintain biliary duct patency in AE associated pathology and probably contributes to avoid or postpone bilio-digestive anastomosis. This approach is in accordance with current

    The Medpor porous polyethylene implant provides benefits to perform sellar floor reconstruction when indicated. This material has been used for cranioplasty and reconstruction of skull base defects and facial fractures. We present the most extensive use of this implant for sellar floor reconstruction and document the safety and benefits provided by this unique implant. The medical charts for 200 consecutive patients undergoing endonasal transsphenoidal surgery from April 2008 through December 2011 were reviewed. Material used for sellar floor reconstruction, pathologic diagnosis, immediate inpatient complications, and long-term complications were documented and analyzed. Outpatient follow-up was documented for a minimum of 1-year duration, extending in some patients up to 5 years. Of the 200 consecutive patients, 136 received sellar floor cranioplasty using the Medpor implant. Postoperative complications included 6 complaints of sinus irritation or drainage, 1 postoperative cerebrospinal fluid leak requiring operative re-exploration, 1 event of tension pneumocephalus requiring operative decompression, 1 case of aseptic meningitis, 1 subdural hematoma, and 1 case of epistaxis. The incidence of these complications did not differ from the autologous nasal bone group in a statistically significant manner. Sellar floor reconstruction remains an important part of transsphenoidal surgery to prevent postoperative complications. Various autologous and synthetic options are available to reconstruct the sellar floor, and the Medpor implant is a safe and effective option. The complication rate after surgery is equivalent to or less frequent than other methods of reconstruction and the implant is readily incorporated into host tissue after implantation, minimizing infectious risk.

    Deoxycholic acid (DCA) is approved for improvement in the appearance of moderate to severe convexity or fullness associated with submental fat. To assess early treatment experience with DCA injection in a clinical practice setting. In this single-center, prospective, single-arm, observational study, 100 consecutive patients seeking to decrease submental fullness received subcutaneous DCA (2 mg/cm) injections in the submental area (maximum of 6 sessions at ≥1 month intervals). Treatment response was assessed 1 and 5 to 7 weeks posttreatment using the clinician-reported submental fat rating scale (CR-SMFRS) and retrospective independent photograph review by 2 physicians. Overall, 100 patients had 152 treatment sessions (58, 33, 8, and 1 patients had 1, 2, 3, and 4 sessions, respectively). CR-SMFRS score improved by ≥1 point from baseline in 88 (88%) patients; of these, 46, 33, 8, and 1 patients had 1, 2, 3, and 4 sessions, respectively. Local edema, numbness, and tenderness were reported for a mean (SD) of 7.7 (5.3), 28.5 (11.4), and 3.5 (3.5) days, respectively. Two patients experienced marginal mandibular nerve paresis. Deoxycholic acid injection, a minimally invasive procedure for neck contouring, was effective and generally well tolerated in the private practice setting.

    We sought to assess outcomes after endovascular treatment/therapy of acute ischemic stroke, overall and by subgroups, and looked for predictors of outcome. We used data from a mandatory, population-based registry that includes external monitoring of completeness, which assesses reperfusion therapies for consecutive patients with acute ischemic stroke since 2011. We described outcomes overall and by subgroups (age ≤ or >80 years; onset-to-groin puncture ≤ or >6 hours; anterior or posterior strokes; previous IV recombinant tissue-type plasminogen activator or isolated endovascular treatment/therapy; revascularization or no revascularization), and determined independent predictors of good outcome (modified Rankin Scale score ≤2) and mortality at 3 months by multivariate modeling. We analyzed 536 patients, of whom 285 received previous IV recombinant tissue-type plasminogen activator. Overall, revascularization (modified Thrombolysis In Cerebral Infarction scores, 2b and 3) occurred in 73.9%, 5.6% developed symptomatic intracerebral hemorrhages, 43.3% achieved good functional outcome, and 22.2% were dead at 90 days. Adjusted comparisons by subgroups systematically favored revascularization (lower proportion of symptomatic intracerebral hemorrhages and death rates and higher proportion of good outcome). Multivariate analyses confirmed the independent protective effect of revascularization. Additionally, age >80 years, stroke severity, hypertension (deleterious), atrial fibrillation, and onset-to-groin puncture ≤6 hours (protective) also predicted good outcome, whereas lack of previous disability and anterior circulation strokes (protective) as well as and hypertension (deleterious) independently predicted mortality. This study reinforces the role of revascularization and time to treatment to achieve enhanced functional outcomes and identifies other clinical features that independently predict good/fatal outcome after endovascular treatment/therapy.

    The 2008 World Health Organization (WHO) criteria were used to identify 88 consecutive Mayo Clinic patients with 'myelodysplastic syndrome with isolated del(5q)' (median age 74 years; 60 females). In all, 60 (68%) patients were followed up to the time of their death. Overall median survival was 66 months; leukemic transformation was documented in five (5.7%) cases. Multivariable analysis identified age >or=70 years (P=0.01), transfusion need at diagnosis (P=0.04) and dysgranulopoiesis (P=0.02) as independent predictors of shortened survival; the presence of zero (low risk), one (intermediate risk) or >or=2 (high risk) risk factors corresponded to median survivals of 102, 52 and 27 months, respectively. Janus kinase 2 (JAK2), thrombopoietin receptor (MPL), isocitrate dehydrogenase 1 (IDH1) and IDH2 mutational analysis was performed on archived bone marrows in 78 patients; JAK2V617F and MPLW515L mutations were shown in five (6.4%) and three (3.8%) patients, respectively, and did not seem to affect phenotype or prognosis. IDH mutations were not detected. Survival was not affected by serum ferritin and there were no instances of death directly related to iron overload. The current study is unique in its strict adherence to WHO criteria for selecting study patients and providing information on long-term survival, practical prognostic factors, baseline risk of leukemic transformation and the prevalence of JAK2, MPL and IDH mutations.

    Cervical spondylolysis, with or without spondylolisthesis, is a rare condition defined as a corticated cleft between the superior and inferior articular facets of the articular pillar. The defect occurs predominantly at C6, and is usually bilateral in up to two-thirds of cases. Multilevel involvement is uncommon, however, to date, no case of two consecutive levels of unilateral cervical spondylolysis on opposite sides has been reported. Here, we report a rare case of a patient affected by two consecutive levels of unilateral cervical spondylolysis at C5 and C6 on opposite sides in a 19-year-old male complaining of neck pain.

    Dengue is a widely spread arboviral disease in tropical and subtropical regions of the world. Dengue fever presents clinical characteristics similar to other febrile illness. Thus laboratory diagnosis is important for adequate management of the disease. The present study was designed to evaluate the diagnostic performance of real-time PCR and serological methods for dengue in a real epidemic context. Clinical data and blood samples were collected from consecutive patients with suspected dengue who attended a primary health care unit in Belo Horizonte, Brazil. Serologic methods and real-time PCR were performed in serum samples to confirm dengue diagnosis. Among the 181 consecutive patients enrolled in this study with suspected dengue, 146 were considered positive by serological criteria (positive NS1 ELISA and/or anti-dengue IgM ELISA) and 138 were positive by real-time PCR. Clinical criteria were not sufficient for distinguishing between dengue and non-dengue febrile illness. The PCR reaction was pre-optimized using samples from patients with known viral infection. It had similar sensitivity compared to NS1 ELISA (88% and 89%, respectively). We also evaluated three commercial lateral flow immunochromatographic tests for NS1 detection (BIOEASY, BIORAD and PANBIO). All three tests showed high sensitivity (94%, 91% and 81%, respectively) for dengue diagnosis. According to our results it can be suggested that lateral flow tests for NS1 detection are the most feasible methods for early diagnosis of dengue. Copyright © 2013 Elsevier B.V.

    Although implementation of temozolomide (TMZ) as a part of primary therapy for glioblastoma multiforme (GBM) has resulted in improved patient survival, the disease is still incurable. Previous studies have correlated various parameters to survival, although no single parameter has yet been identified. More studies and new approaches to identify the best and worst performing patients are therefore in great demand. This study examined 225 consecutive, non-selected GBM patients with performance status (PS) 0–2 receiving postoperative radiotherapy with concomitant and adjuvant TMZ as primary therapy. At relapse, patients with PS 0–2 were mostly treated by reoperation and/or combination with bevacizumab/irinotecan (BEV/IRI), while a few received TMZ therapy if the recurrence-free period was >6 months. Median overall survival and time to progression were 14.3 and 8.0 months, respectively. Second-line therapy indicated that reoperation and/or BEV/IRI increased patient survival compared with untreated patients and that BEV/IRI was more effective than reoperation alone. Patient age, ECOG PS, and use of corticosteroid therapy were significantly correlated with patient survival and disease progression on univariate analysis, whereas p53, epidermal growth factor receptor, and O 6 -methylguanine-DNA methyltransferase expression (all detected by immunohistochemistry), tumor size or multifocality, and extent of primary operation were not. A model based on age, ECOG PS, and corticosteroids use was able to predict survival probability for an individual patient. The survival of RT/TMZ-treated GBM patients can be predicted based on patient age, ECOG PS, and corticosteroid therapy status

    Long-term results of patients undergoing laryngotracheal resection for benign stenosis are reported. This is the largest series ever published. Between 1991 and March 2015, 109 consecutive patients (64 males, 45 females; mean age 39 ± 10.9 years) underwent laryngotracheal resection for subglottic postintubation (93) or idiopathic (16) stenosis. Preoperative procedures included tracheostomy in 35 patients, laser in 17 and laser plus stenting in 18. The upper limit of the stenosis ranged between actual involvement of the vocal cords and 1.5 cm from the glottis. Airway resection length ranged between 1.5 and 6 cm (mean 3.4 ± 0.8 cm) and it was over 4.5 cm in 14 patients. Laryngotracheal release was performed in 9 patients (suprahyoid in 7, pericardial in 1 and suprahyoid + pericardial in 1). There was no perioperative mortality. Ninety-nine patients (90.8%) had excellent or good early results. Ten patients (9.2%) experienced complications including restenosis in 8, dehiscence in 1 and glottic oedema requiring tracheostomy in 1. Restenosis was treated in all 8 patients with endoscopic procedures (5 laser, 2 laser + stent, 1 mechanical dilatation). The patient with anastomotic dehiscence required temporary tracheostomy closed after 1 year with no sequelae. One patient presenting postoperative glottic oedema underwent permanent tracheostomy. Minor complications occurred in 4 patients (3 wound infections, 1 atrial fibrillation). Definitive excellent or good results were achieved in 94.5% of patients. Twenty-eight post-coma patients with neuropsychiatric disorders showed no increased complication and failure rate. Laryngotracheal resection is the definitive curative treatment for subglottic stenosis allowing very high success rate at long term. Early complications can be managed by endoscopic procedures achieving excellent and stable results over time. © The Author 2016.

    Outcomes in primary amyloid renal patients are of interest as the era of monoclonal antibody therapies begins. We studied 77 consecutive primary amyloid renal patients (58% men) for renal progression (end stage renal disease [ESRD]), renal response (RR), and overall survival (OS). At diagnosis median age was 63 (range, 35-81) years, estimated glomerular filtration rate 70 mL/min (range, 5-114), difference between involved and uninvolved free light chains 127 mg/L (range, 1-9957), ESRD 4%, renal stage 2 and 3 78%, and cardiac stage 2 and 3 56%. Ninety-six percent received bortezomib and 44% stem cell transplantation as well as bortezomib, 68% achieved complete or very good partial hematologic response (CR/VGPR), 34% had ESRD, and 39% RR. Median times to ESRD and RR were 18 (range, 3-81) and 12 (range, 2-30) months, respectively. Median OS was not reached in this cohort and was not reached from onset of ESRD. More than two-thirds of patients with ESRD also achieved CR/VGPR. In those without ESRD at diagnosis, baseline creatinine and absent RR predicted progression to ESRD in multivariate Cox regression analysis, whereas CR/VGPR predicted RR. In multivariate Cox regression analysis, cardiac stage and achievement of CR/VGPR predicted OS, enabling construction of a prognostic model. Anti-plasma cell therapies provide a definite albeit limited benefit and new approaches to amyloid-related organ dysfunction are needed. Copyright © 2017 Elsevier Inc. All rights reserved.

    Open-access scheduling is highly utilized for facilitating generally low-risk endoscopies. Preprocedural screening addresses sedation requirements; however, procedural safety may be compromised if screening is inaccurate. We sought to determine the reliability of our open-access scheduling system for appropriate use of conscious sedation. We prospectively and consecutively enrolled outpatient procedures booked at an academic center by open-access using screening after in-office gastroenterology (GI) consultation. We collected the cases inappropriately booked for conscious sedation and compared the characteristics for significant differences. A total of 8063 outpatients were scheduled for procedures with conscious sedation, and 5959 were booked with open-access. Only 78 patients (0.97%, 78/8063) were identified as subsequently needing anesthesiologist-assisted sedation; 44 (56.4%, 44/78) were booked through open-access, of which chronic opioid (47.7%, 21/44) or benzodiazepine use (34.1%, 15/44) were the most common reasons for needing anesthesiologist-assisted sedation. Patients on chronic benzodiazepines required more midazolam than those not on chronic benzodiazepines (P = .03) of those patients who underwent conscious sedation. Similarly, patients with chronic opioid use required more fentanyl than those without chronic opioid use (P = .04). Advanced liver disease and alcohol use were common reasons for patients being booked after in-office consultation and were significantly higher than those booked with open-access (both P open-access scheduling. © The Author(s) 2016.

    AimTo present our single-centre prospective experience on the use of cryoablation (CA) applied to treat primary breast cancer (BC) in a cohort of patients unsuitable for surgical treatment.Materials and MethodsTwenty-three consecutive post-menopausal female patients (median age 85 years; range 56–96) underwent percutaneous CA of unifocal, biopsy-proven BC, under ultrasound/computed tomography (US/CT) guidance. Clinical and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) follow-ups were systematically scheduled at 3, 12, 18 and 24 months. Local tumour control was assessed by comparing baseline and follow-up DCE-MRI.ResultsTwenty-three BC (median size 14 mm) were treated under local anaesthesia (78.3 %) or local anaesthesia and conscious sedation (21.7 %). Median number of cryo-probes applied per session was 2.0. A “dual-freezing” protocol was applied for the first ten patients and a more aggressive “triple-freezing” protocol for the remaining 13. Median follow-up was 14.6 months. Five patients recurred during follow-up and two were successfully re-treated with CA. Five patients presented immediate CA-related complications: four hematomas evolved uneventfully at 3-month follow-up and one skin burn resulted in skin inflammation and skin retraction at 3 and 12 months, respectively.ConclusionsPercutaneous CA is safe and well tolerated for non-resected elderly BC patients. Procedures can be proposed under local anaesthesia only. Given the insulation properties of the breast gland, aggressive CA protocols are required. Prospective studies are needed to better understand the potential role of CA in the local treatment of early BC

    In this retrospective study the results of primary and salvage treatment of oropharyngeal carcinoma were evaluated. A total of 289 consecutive patients (103 females and 186 males) were included in the study. Most tumours originated in the tonsil area (58%) and comprised stages I 8%, II 19%, III 46% and IV 28%. The primary treatment was delivered with curative intent in 276 cases (96%). Of these, 266 received primary radiotherapy. The median radiation dose was 62 Gy, given as laterally opposed fields to the primary tumour and bilateral neck. Eight patients were treated with primary surgery and two with chemotherapy as part of a curatively intended treatment programme including radiotherapy. Six patients received palliative treatment, and seven were not treated at all. Out of 276 tumours treated with curative intent, 173 reappeared; 72% recurred in T position, 38% in N position, and 12% at distant metastatic sites, some in combination. Salvage surgery was possible in 52 patients, and 24 treatments were successful. Salvage radiotherapy or cryotherapy was used in 22 patients and 4 were controlled. For the entire group, the 5-year locoregional tumour control, disease-specific survival and overall survival rates were 38%, 44% and 31%, respectively. For patients treated with curative intent, clinical T- and N-stage, stage, tumour size, gender, age, and pretreatment haemoglobin were significant prognostic parameters in a univariate analysis. The Cox multivariate analysis showed that T-stage, N-stage and gender were independent prognostic factors. It is concluded that T-stage, N-stage and gender are significant independent prognostic factors. The primary control of the carcinoma in the T-position is crucial for overall success, but salvage surgery is found to have a favourable success rate in patients suitable for relapse treatment

    The aim of this study was to evaluate whether mobile kidney pain provocation ultrasonography together with intravenous pyelography in supine and standing positions and a full medical history can confirm the diagnosis of the clinical condition of symptomatic mobile kidney and aid the selection of patients for surgical treatment. In a consecutive study, 43 patients with the clinical picture of symptomatic mobile kidney, a positive mobile kidney pain provocation ultrasonography and a renal descent of at least 2 lumbar vertebral heights on intravenous pyelography in the standing position, were operated on with nephropexy. Patients' pain relief after nephropexy was evaluated by clinical follow-up, a questionnaire and visual analogue scale (VAS) scoring. Reduction of pain after nephropexy was associated with a significant decrease in VAS scoring from a median of 8 (range 4-10) preoperatively to a median of 0 (range 0-7) postoperatively (p mobile kidney pain provocation ultrasonography and intravenous pyelography in supine and standing positions can verify the diagnosis of symptomatic mobile kidney and aid the selection of patients who will benefit from nephropexy.

    Full Text Available Context: Type 2 diabetes mellitus doubles the odds of suffering from depressive illness. Co-morbid depression is associated with poorer outcomes in diabetes mellitus in terms of glycemic control, medication adherence, quality of life, physical activity, and blood pressure control. Aim: The present study aims to estimate the prevalence of depression among a consecutive group of patients with type 2 diabetes and assess its impact on glycemic and blood pressure control. Setting: Outpatient department of the endocrinology department of a university affiliated teaching hospital in north India. Subjects: Consecutive adult patients (18-65 years with type 2 diabetes mellitus of over 5-year duration with no prior history of psychiatric illnesses or intake of anti-depressants. Materials and Methods: A semi-structured questionnaire was used for demographic data, HbA1c was obtained to assess glycemic control, and blood pressure was recorded twice during patient interview to assess blood pressure control. Depression was assessed with the Major Depression Inventory and scores obtained were classified as consistent with mild, moderate and severe depression. Data was analyzed with SPSS v16, and multiple logistical regression test was done to compare the effect of depression on glycemic control after adjusting for age and sex. Results: Of the 80 patients interviewed, 31 (38.8% had depressive symptoms. Among them 20 (25% had mild depression, 10 (12.5% had moderate depression, and 1 (1.3% had severe depression. Conclusions: Over one third of patients with type 2 diabetes mellitus of over 5-year duration had depressive symptoms. The presence of depressive symptoms was associated with a significant worsening of glycemic control.

    The 2008 World Health Organization (WHO) criteria were used to identify 88 consecutive Mayo Clinic patients with ‘myelodysplastic syndrome with isolated del(5q)' (median age 74 years; 60 females). In all, 60 (68%) patients were followed up to the time of their death. Overall median survival was 66 months; leukemic transformation was documented in five (5.7%) cases. Multivariable analysis identified age ⩾70 years (P=0.01), transfusion need at diagnosis (P=0.04) and dysgranulopoiesis (P=0.02) as independent predictors of shortened survival; the presence of zero (low risk), one (intermediate risk) or ⩾2 (high risk) risk factors corresponded to median survivals of 102, 52 and 27 months, respectively. Janus kinase 2 (JAK2), thrombopoietin receptor (MPL), isocitrate dehydrogenase 1 (IDH1) and IDH2 mutational analysis was performed on archived bone marrows in 78 patients; JAK2V617F and MPLW515L mutations were shown in five (6.4%) and three (3.8%) patients, respectively, and did not seem to affect phenotype or prognosis. IDH mutations were not detected. Survival was not affected by serum ferritin and there were no instances of death directly related to iron overload. The current study is unique in its strict adherence to WHO criteria for selecting study patients and providing information on long-term survival, practical prognostic factors, baseline risk of leukemic transformation and the prevalence of JAK2, MPL and IDH mutations.

    (1) To analyze peculiarities of presentation and prognosis of tubercular spondylodiscitis (TBS) in elderly. (2) To assess if associated co-morbidities and risks lead to poorer outcome (3) To observe if different management strategy needs to be implemented in them. Retrospective analysis of 66 consecutive elderly TBS patients (>60 years) treated conservatively or surgically between January 2010 and July 2013 was performed. Details regarding clinical presentation (general health, ambulatory status, co-morbidities), neurological status, medical or surgical complications and outcome measurements [visual analog score, clinico-radiological evidence of healing and lumbar lordosis in lumbar (L) or lumbo-sacral (LS) or focal kyphosis in thoracic (T) or thoraco-lumbar (TL) disease] were analysed. Of 66 patients (mean age 67.9 years), 85% had at least one medical co-morbidity and only 45% were community ambulators. Mean delay in presentation was 132 days and lumbar disease was commonest. 35% had neuro-deficit. Most patients had stage 2 (38%) or 3 (42.4%) disease. 19 patients were conservatively managed, while others underwent surgery. Significant complications occurred in 23 patients, most common being liver dysfunction (9 patients). Five patients (8%) expired during treatment: three succumbed to multi-focal tubercular disease, while two expired secondary to medical illnesses. Mean loss of lordosis in conservatively treated (CG) L/LS disease was 8°, while lordosis was restored by 11.6° in operative group (OG). In T/TL disease, sagittal alignment correction by 12.6° was observed in OG as against 5.7° kyphotic collapse in CG patients. 92% patients were cured with no recurrences. The final VAS scores in operative and conservative groups were not significantly different (OG 1.4 ± 0.6, CG 1.9 ± 0.7). TBS in elderly differed from that in younger by having a higher co-morbidities, later presentation, higher neuro-deficit, greater mortality and increased complications

    Shoulder arthroplasty surgery has undergone remarkable progress. New concepts like reverse and stemless shoulder prostheses have been widely used. The Total Evolutive Shoulder System (TESS) is a new innovative system that provides the surgeon with different prosthetic versions. The purpose of the present study was to evaluate our short-term results and complications of the TESS. 56 consecutive patients were operated with one of the two versions of TESS (anatomical or reverse) between October 2007 and December 2009. Preoperative and postoperative evaluation of the function and life quality was achieved by the Quick Disability of the Arm, Shoulder and Hand (DASH) index and EQ-5D self-report questionnaire, respectively. Radiographic follow-up by anteroposterior, axillary and lateral views was done. The anterosuperior approach was used in all cases. We compared the outcome in fracture patients with other categories. 49 patients were available for 9-24 months (mean 14) clinical and radiographic postoperative follow-up. The mean of quick DASH improved from 56 preoperatively to 34 postoperatively (p TESS prosthesis showed promising short-term results with few complications. The reverse version could be implanted without stem if initial stability was adequate. Long-term follow-up is required to confirm the results of this innovative system in the long run.

    To analyze the relationship between consecutive deterioration of mean deviation (MD) value and glaucomatous visual field (VF) progression in open-angle glaucoma (OAG), including primary OAG and normal tension glaucoma. The subjects of the study were patients undergoing treatment for OAG who had performed VF tests at least 10 times with a Humphrey field analyzer (SITA standard, C30-2 program). The VF progression was defined by a significantly negative MD slope (MD slope worsening) at the final VF test during the follow-up period. The relationship between the MD slope worsening and the consecutive deterioration of MD value were retrospectively analyzed. A total of 165 eyes of 165 patients were included in the analysis. Significant progression of VF defects was observed in 72 eyes of 72 patients (43.6%), while no significant progression was evident in 93 eyes of 93 patients (56.4%). There was significant relationship between the frequency of consecutive deterioration of MD value and MD slope worsening (P<0.0001, Cochran-Armitage trend test). A significant association was observed for MD slope worsening in the eyes with three (odds ratio: 2.1, P=0.0224) and four (odds ratio: 3.6, P=0.0008) consecutive deterioration of MD value in multiple logistic regression analysis, but no significant association in the eyes with two consecutive deterioration (odds ratio: 1.1, P=0.8282). The eyes with VF progression had significantly lower intraocular pressure reduction rate (P<0.01). This retrospective study has shown that three or more consecutive deterioration of MD value might be a predictor to future significant MD slope worsening in OAG.

    Full Text Available BACKGROUND: From long instances, it is debatable whether three sputum specimens are required for the diagnosis of pulmonary tuberculosis (TB or TB can be diagnosed effectively using two consecutive sputum specimens. This study was set out to evaluate the significance of examining multiple sputum specimens in diagnosis of TB. METHODS: We retrospectively reviewed the acid-fast bacillus (AFB smear and culture results of three consecutive days' sputum specimens from 413 confirmed TB patients which were detected as part of a larger active case finding study in Dhaka Central Jail, the largest correctional facility in Bangladesh. RESULTS: AFB was detected from 81% (n = 334 patients, of which 89% (n = 297 were diagnosed from the first and additional 9% (n = 30 were from the second sputum specimen. M. tuberculosis growth was observed for 406 patients and 85% (n = 343 were obtained from the first sputum and additional 10% (n = 42 were from the second one. The third specimen didn't show significant additional diagnostic value for the detection of AFB by microscopy or growth of the M. tuberculosis. CONCLUSIONS: We concluded from our study results that examining two consecutive sputum specimens is sufficient enough for the effective diagnosis of TB. It can also decrease the laboratory workload and hence improve the quality of work in settings with high TB burden like Bangladesh.

    From long instances, it is debatable whether three sputum specimens are required for the diagnosis of pulmonary tuberculosis (TB) or TB can be diagnosed effectively using two consecutive sputum specimens. This study was set out to evaluate the significance of examining multiple sputum specimens in diagnosis of TB. We retrospectively reviewed the acid-fast bacillus (AFB) smear and culture results of three consecutive days' sputum specimens from 413 confirmed TB patients which were detected as part of a larger active case finding study in Dhaka Central Jail, the largest correctional facility in Bangladesh. AFB was detected from 81% (n = 334) patients, of which 89% (n = 297) were diagnosed from the first and additional 9% (n = 30) were from the second sputum specimen. M. tuberculosis growth was observed for 406 patients and 85% (n = 343) were obtained from the first sputum and additional 10% (n = 42) were from the second one. The third specimen didn't show significant additional diagnostic value for the detection of AFB by microscopy or growth of the M. tuberculosis. We concluded from our study results that examining two consecutive sputum specimens is sufficient enough for the effective diagnosis of TB. It can also decrease the laboratory workload and hence improve the quality of work in settings with high TB burden like Bangladesh.

    Full Text Available A consecutive colouring of a graph is a proper edge colouring with posi- tive integers in which the colours of edges incident with each vertex form an interval of integers. The idea of this colouring was introduced in 1987 by Asratian and Kamalian under the name of interval colouring. Sevast- janov showed that the corresponding decision problem is NP-complete even restricted to the class of bipartite graphs. We focus our attention on the class of consecutively colourable graphs whose all induced subgraphs are consecutively colourable, too. We call elements of this class perfect consecutively colourable to emphasise the conceptual similarity to perfect graphs. Obviously, the class of perfect consecutively colourable graphs is induced hereditary, so it can be characterized by the family of induced forbidden graphs. In this work we give a necessary and sufficient conditions that must be satisfied by the generalized Sevastjanov rosette to be an induced forbid- den graph for the class of perfect consecutively colourable graphs. Along the way, we show the exact values of the deficiency of all generalized Sevastjanov rosettes, which improves the earlier known estimating result. It should be mentioned that the deficiency of a graph measures its closeness to the class of consecutively colourable graphs. We motivate the investigation of graphs considered here by showing their connection to the class of planar perfect consecutively colourable graphs.

    We investigated retrospectively perioperative and long-term complications of carotid endarterectomy (CEA) in 232 consecutive cases. Perioperative complications in surgical patients are 2.2% with no mortality. There was no perioperative embolic stroke in the later series of 130 CEA, although postoperative hyperperfusion was associated in two patients with edema and bleeding in their watershed area. We encountered 16 cases of pseudoocclusion, 11 cases were collapsed carotid arteries treated successfully by thromboendarterectomy, and 5 thrombosed cases were treated by CEA and thrombectomy, resulting in poor outcome. Thirteen cases of CEA with contlateral occlusion were performed uneventfully under intraluminal shunting. Redo operation for recurrent stenosis were performed successfully in 1.3% with patching. In the long-term follow-up of 118 consecutive cases, CEA had a clear benefit of preventing ipsilateral stroke in the first 3 years, but actual risks in long-term surgical patients were influenced more by their cardiac events than the stroke. Our findings suggest that managing cardiac events significantly affects life expectancy. (author)

    Purpose: Percutaneous vertebroplasty (PV) is a minimally invasive procedure involving the injection of bone cement within a collapsed vertebral body. Although this procedure was demonstrated to be effective in osteoporosis and metastases, few studies have been reported in cases of multiple myeloma (MM). We prospectively evaluated the safety and efficacy of PV in the treatment of vertebral compression fractures (VCFs) resulting from MM. Materials and Methods: PV was performed in 106 consecutive MM patients who had back pain due to VCFs, the treatment of which had failed conservative therapies. Follow-up (28.2 ± 12.1 months) was evaluated at 7 and 15 days as well as at 1, 3, 6, 12, 18, and every 6 months after PV. Visual analog scale (VAS) pain score, opioid use, external brace support, and Oswestry Disability Index (ODI) score were recorded. Results: The median pretreatment VAS score of 9 (range 4–10) significantly (P < 0.001) decreased to 1 (range 0–9) after PV. Median pre-ODI values of 82% (range 36–89%) significantly improved to 7% (range 0–82%) (P < 0.001). Differences in pretreatment and posttreatment use of analgesic drug were statistically significant (P < 0.001). The majority of patients (70 of 81; 86%) did not use an external brace after PV (P < 0.001). Conclusion: PV is a safe, effective, and long-lasting procedure for the treatment of vertebral compression pain resulting from MM.

    Objective Unplanned readmission within 30 days is a contributor to health care costs in the United States. The use of predictive modeling during hospitalization to identify patients at risk for readmission offers a novel approach to quality improvement and cost reduction. Study Design Two-phase study including retrospective analysis of prospectively collected data followed by prospective longitudinal study. Setting Tertiary academic medical center. Subjects and Methods Prospectively collected data for patients undergoing surgical treatment for head and neck cancer from January 2013 to January 2015 were used to build predictive models for readmission within 30 days of discharge using logistic regression, classification and regression tree (CART) analysis, and random forests. One model (logistic regression) was then placed prospectively into the discharge workflow from March 2016 to May 2016 to determine the model's ability to predict which patients would be readmitted within 30 days. Results In total, 174 admissions had descriptive data. Thirty-two were excluded due to incomplete data. Logistic regression, CART, and random forest predictive models were constructed using the remaining 142 admissions. When applied to 106 consecutive prospective head and neck oncology patients at the time of discharge, the logistic regression model predicted readmissions with a specificity of 94%, a sensitivity of 47%, a negative predictive value of 90%, and a positive predictive value of 62% (odds ratio, 14.9; 95% confidence interval, 4.02-55.45). Conclusion Prospectively collected head and neck cancer databases can be used to develop predictive models that can accurately predict which patients will be readmitted. This offers valuable support for quality improvement initiatives and readmission-related cost reduction in head and neck cancer care.

    We hypothesized that nonlocalizing sestamibi scans would correlate with multigland disease and persistent primary hyperparathyroidism. We reviewed records for 401 consecutive patients who underwent parathyroidectomy from 1999 to 2004. Gender, age, preoperative imaging, surgical findings, gland weight and volume, and 6-month calcium levels (Ca) were examined. We identified 289 women and 112 men, 297 of whom had a preoperative sestamibi scan localized to a single gland (localized group; LG). Ninety-six percent of the LG were found to have single-gland disease, and 4% had multigland disease (MGD). In the nonlocalized group (NLG), 76% had single-gland disease and 24% MGD. Mean gland weight was greater in the LG than in the NLG (1128 mg vs 699 mg; P localizing sestamibi scan had a positive predictive value (PPV) of 96% and a likelihood ratio of 2.29 for predicting "curative" intraoperative parathyroid hormone drop after removal of a single abnormal gland. Patients were stratified into normocalcemic (NCa) and hypercalcemic (HCa) groups based on 6-month postoperative serum calcium data (n = 328). HCa incidence at 6 months did not differ significantly between the LG (5%) and NLG (3%). A localizing scan had a PPV of 95% for normocalcemia at 6 months. A nonlocalizing scan had a PPV of 21% for HCa at 6 months. Nonlocalizing sestamibi scans were more common in primary hyperparathyroidism with MGD and were associated with smaller-volume abnormal glands found at operation. Preoperative sestamibi scan-results did not predict HCa at 6 months.

    Several markers have been associated with sarcopenia in the elderly, including bioelectrical indices. Phase angle (PhA) is an impedance parameter and it has been suggested as an indicator of cellular death. Thus, the relationship between PhA and muscle mass and strength was investigated in 207 consecutively elderly participants (mean age 76.2±6.7years) admitted for multidimensional geriatric evaluation. Muscle strength by grip strength using a hand-held dynamometer and muscle mass was measured by bioimpedentiometer. PhA was calculated directly with its arctangent (resistance/reactance×180°/π). Linear relationship among muscular mass and strength and with clinical and biochemical parameters, including PhA at uni- and multivariate analysis were performed. Linear regression analysis demonstrated that lower level of PhA is associated with reduction in grip strength (y=3.16+0.08x; r=0.49; pelderly subjects and it may be considered a good bioelectrical marker to identify elderly patients at risk of sarcopenia.

    To determine prevalence and risk factors for renal scar in children referred for urologic assessment of febrile UTI and/or VUR. Pre-determined risk factors for renal scar were prospectively recorded in consecutive patients referred for UTI/VUR. Age, gender, VUR grade, and reported number of febrile and non-febrile UTIs were analyzed with logistic regression to determine risk for focal cortical defects on non-acute DMSA. Of 565 consecutive children, 24 (4%) had congenital renal dysplasia and 84 (15.5%) had focal defect(s). VUR, especially grades IV-V, recurrent febrile UTI, and older age increased risk. For any age child with the same number of UTIs, VUR increased odds of renal defect 5.4-fold (OR = 5.4, 95% CI = 2.7-10.6, AUC = 0.759). Focal DMSA defects were present in 15.5% of 565 consecutive children referred for febrile UTI and/or VUR; 4% had presumed congenital reflux nephropathy without cortical defect. All VUR grades increased risk for these defects, as did recurrent febrile UTIs and older age. However, 43% with grades IV-V VUR and 76% with recurrent UTI had normal DMSA. Published by Elsevier Ltd.

    The treatment of complicated pleural infection (CPI) is controversial. Clinical guidelines recommend drainage, but with the lowest grade of evidence. Recent reports have observed good outcomes with antibiotics alone. We retrospectively compared the outcomes in two consecutive cohorts treated with different policies: the first treated according to pleural fluid charactersitics (2005-2009, interventional-prone, group 1) and the second according to clinical assessment (2010-2013, conservative-prone, group 2). The clinical records of all children treated for CPI in our hospital between 2005 and 2013 were thoroughly reviewed. Primary outcomes were the proportion of children drained and the length of hospital stay (LHS). One hundred and nine patients (64 group 1 and 45 group 2) were analyzed. A chest tube was placed in 83% of patients in group 1 and 47% in group 2 (Pdrain most children with CPI. Clinical trials are now needed to identify when a drainage procedure would be useful.

    Coronary artery bypass grafting (CABG) with incomplete revascularization (ICR) is thought to decrease survival. We studied the survival of patients with ICR undergoing total arterial grafting. In a consecutive series of all-comer 1000 patients with isolated CABG, operative and midterm survival were assessed for patients undergoing complete versus ICR, with odds ratios and hazard ratios, adjusted for European System for Cardiac Operative Risk Evaluation category, CABG urgency, age, and comorbidities. In this series of 1000 patients with 98% arterial grafts (2922 arterial, 59 vein grafts), 73% of patients with multivessel disease received bilateral internal mammary artery grafts. ICR occurred in 140 patients (14%). Operative mortality was 3.8% overall, 8.6% for patients with ICR, and 3.2% for patients with complete revascularization (P = .008). For operative mortality using multivariable logistic regression, after controlling for European System for Cardiac Operative Risk Evaluation category (P System for Cardiac Operative Risk Evaluation category (P reserved.

    In the last decade, costs of U.S. healthcare expenditures have been soaring, with billions of dollars spent on hospital readmissions. Identifying causes and risk factors can reduce soaring readmission rates and help lower healthcare costs. The aim of this is to determine if post-operative delirium in the elderly is an independent risk factor for 30-day hospital readmission after spine surgery. The medical records of 453 consecutive elderly (≥65years old) patients undergoing spine surgery at Duke University Medical Center from 2008 to 2010 were reviewed. We identified 17 (3.75%) patients who experienced post-operative delirium according to DSM-V criteria. Patient demographics, comorbidities, and post-operative complication rates were collected for each patient. Elderly patients experiencing post-operative delirium had an increased length of hospital stay (10.47days vs. 5.70days, p=0.009). Complication rates were similar between the cohorts with the post-operative delirium patients having increased UTI and superficial surgical site infections. In total, 12.14% of patients were re-admitted within 30-days of discharge, with post-operative delirium patients experiencing approximately a 4-fold increase in 30-day readmission rates (Delirium: 41.18% vs. No Delirium: 11.01%, p=0.002). In a multivariate logistic regression analysis, post-operative delirium is an independent predictor of 30-day readmission after spine surgery in the elderly (p=0.03). Elderly patients experiencing post-operative delirium after spine surgery is an independent risk factor for unplanned readmission within 30-days of discharge. Preventable measures and early awareness of post-operative delirium in the elderly may help reduce readmission rates. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The purpose of this study was to determine the information needs of primary care patients as they review clinic visit notes to inform information that should be contained in an after-visit summary (AVS). We collected data from 15 patients with an acute illness and 14 patients with a chronic disease using semi-structured interviews. The acute patients reviewed seven major sections, and chronic patients reviewed eight major sections of a simulated, but realistic visit note to identify relevant information needs for their AVS. Patients in the acute illness group identified the Plan, Assessment and History of Present Illness the most as important note sections, while patients in the chronic care group identified Significant Lab Data, Plan, and Assessment the most as important note sections. This study was able to identify primary care patients' information needs after clinic visit. Primary care patients have information needs pertaining to diagnosis and treatment, which may be the reason why both patient groups identified Plan and Assessment as important note sections. Future research should also develop and assess an AVS based on the information gathered in this study and evaluate its usefulness among primary care patients. The results of this study can be used to inform the development of an after-visit summary that assists patients to fully understand their treatment plan, which may improve treatment adherence.

    Approximately 20% to 30% of patients who undergo coronary angiography for assessment of typical cardiac chest pain display microvascular coronary dysfunction (MCD). This study aimed to determine potential relationships between baseline clinical characteristics and likelihood of MCD diagnosis in a large group of patients with stable angina symptoms, positive exercise test and angiographic ally normal epicardial coronary arteries. This cross-sectional study included 250 Iranian with documented evidence of cardiac ischemia on exercise testing, class I or II indication for coronary angiography, and either: (1) angiographically normal coronary arteries and diagnosis of MCD with slow-flow phenomenon, or (2) normal angiogram and no evidence of MCD. All patients completed a questionnaire designed to capture key data including clinical demographics, past medical history, and social factors. Data was evaluated using single and multivariable logistic regression models to identify potential individual patient factors that might help to predict a diagnosis of MCD. 125 (11.2% of total) patients were subsequently diagnosed with MCD. 125 consecutive control subjects were selected for comparison. The mean age was similar among the two groups (52.38 vs. 53.26%, p=ns), but there was a higher proportion of men in the study group compared to control (42.4 vs. 27.2%, p=0.012). No significant relationships were observed between traditional cardiovascular risk factors (diabetes, hypertension, and dyslipidemia) or body mass index (BMI), and likelihood of MCD diagnosis. However, opium addiction was found to be an independent predictor of MCD on single and multivariable logistic regression model (OR=3.575, 95%CI: 1.418-9.016; p=0.0069). We observed a significant relationship between opium addiction and microvascular angina. This novel finding provides a potential mechanistic insight into the pathogenesis of MCD with slow-flow phenomenon. Copyright © 2016 Elsevier Ireland Ltd. All rights

    Serum alpha-fetoprotein (AFP) level is normal in 30-40% of hepatocellular carcinoma (HCC) patients, and knowledge on its characteristics and clinical outcome is limited. The purpose of this observational study was to determine the clinical presentation, biological behavior and outcome of HCC patients with normal AFP level. Data of 112 consecutive HCC patients with normal AFP level were analyzed retrospectively. Statistical analysis including survival and factors associated with serum AFP level were performed by Kaplan-Meier method and t-test, respectively. Hepatitis B virus infection exited in 83.0% of all 112 HCC patients with normal AFP level. During a mean 52 ± 20 months (range 5-85 months) follow-up, the 1-, 2-, 3-year overall survival (OS) rate was 97.2%, 85.3% and 81.7%, respectively. The OS rates at 3 years stratified by stages at diagnosis were 100%, 96.2%, 85.7%, 11.1% and 0%, respectively for Barcelona Clinic Liver Cancer (BCLC) stage 0-D diseases. Significant difference in OS was observed among patients with BCLC stage 0-D diseases, P level elevated beyond normal figure during follow-up (AFP conversion) in 16 patients, which related with deterioration of liver function, quantitative changes of T helper cell subsets, rapid tumor progression and shorter survival. Patients with sustained normal AFP level had better survival than patients with AFP conversion, P level elevation and the time of AFP elevation to death, P level was relatively optimal. Serum AFP level elevation during follow-up was significantly associated with clinical outcome in terms of OS. © 2017 John Wiley & Sons Australia, Ltd.

    Breast reconstruction often requires multiple operations. In addition to potential complications requiring reoperation, additional procedures are frequently essential in order to complete the reconstructive process, with aesthetic outcome and breast symmetry shown to be the most important factors in patient satisfaction. Despite the importance of these reoperations in decision-making and the consent process, a thorough review of the need for such operations has not been definitively explored. A review of 370 consecutive autologous breast reconstructions (326 patients) was undertaken, comprising 365 deep inferior epigastric artery perforator (DIEP) flaps and 5 superficial inferior epigastric artery (SIEA) flaps. The need for additional procedures for either complications or aesthetic refinement following initial breast reconstruction was assessed. Overall, there was an average of 1.06 additional interventions for every patient carried out after primary reconstructive surgery. Of 326 patients, 46 underwent early postoperative operations for surgical complications (0.17 additional operations per patient as a consequence of complications). Procedures for aesthetic refinement included those performed on the reconstructed breast, contralateral breast, or abdominal donor site. Procedures for aesthetic refinement included nipple reconstruction, nipple-areola complex tattooing, dog-ear correction, liposuction, lipofilling, scar revision, mastopexy, and reduction mammaplasty. While DIEP flap surgery for breast reconstruction provides favorable results, patients frequently require additional procedures to improve aesthetic outcomes. The need for reoperation is an important part of the consent process prior to reconstructive surgery, and patients should recognize the likelihood of at least one additional procedure following initial reconstruction.

    Delirium in older emergency department (ED) patients is associated with severe negative patient outcomes and its detection is challenging for ED clinicians. ED clinicians need easy tools for delirium detection. We aimed to test the performance criteria of the modified Richmond Agitation Sedation Scale (mRASS) in identifying delirium in older ED patients. The mRASS was applied to a sample of consecutive ED patients aged 65 or older by specially trained nurses during an 11-day period in November 2015. Reference standard delirium diagnosis was based on Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria, and was established by geriatricians. Performance criteria were computed. Analyses were repeated in the subsamples of patients with and without dementia. Of 285 patients, 20 (7.0%) had delirium and 41 (14.4%) had dementia. The sensitivity of an mRASS other than 0 to detect delirium was 0.70 (95% confidence interval, CI, 0.48; 0.85), specificity 0.93 (95% CI 0.90; 0.96), positive likelihood ratio 10.31 (95% CI 6.06; 17.51), negative likelihood ratio 0.32 (95% CI 0.16; 0.63). In the sub-sample of patients with dementia, sensitivity was 0.55 (95% CI 0.28; 0.79), specificity 0.83 (95% CI 0.66; 0.93), positive likelihood ratio 3.27 (95% CI 1.25; 8.59), negative likelihood ratio 0.55 (95% CI 0.28; 1.06). The sensitivity of the mRASS to detect delirium in older ED patients was low, especially in patients with dementia. Therefore its usefulness as a stand-alone screening tool is limited.

    Introduction: Gastro-duodenal perforations may be suspected in patients with history of ulceration, who present with acute pain and abdominal wall rigidity, but radiological findings in these cases may be unable to confirm a clinical diagnosis. The aim of our study was to report our experience in the diagnosis of gastro-duodenal perforation by conventional radiography, US and CT examinations. Material and methods: We retrospectively reviewed medical records of 166 consecutive patients who presented in the last 2 years to our institutions with symptoms of acute abdomen and submitted to surgery at the Emergency Unit of the ''A.Cardarelli'' Hospital of Naples with a surgical finding of perforated gastro-duodenal ulcer. The evidence of free intraperitoneal air on abdominal plain film was considered as a direct or suggestive finding of perforation. Evidence of intraperitoneal free fluid and/or reduced intestinal peristalsis at sonographic examination were considered indirect signs of gastro-duodenal perforation. Evidence of free peritoneal gas at CT was considered as a direct evidence of gastro-duodenal perforation. Results: Twenty patients underwent immediate surgery with no preoperative imaging evaluation, in 10 of them the site of perforation was found in a juxta-pyloric region and in the others at level of duodenum. In 146 patients submitted to serial radiological investigations before surgery, the site of perforation was in 56 (38.3%) duodenal, in 52 (35.6%) juxta-pyloric, in 28 (19.1%) gastric and in 10 (6.8%) pyloric. The cause of perforation was in all cases gastric or duodenal ulceration, in seven cases involving pancreatic parenchyma. In 110 (75.4%) patients with direct findings of perforation, in 94 cases (85.5%) the correct diagnosis was established on abdominal plain film, in two (1.8%) with radiographic and sonographic examinations and in 14 (12.7%) on CT findings. In 36 (24,6%) patients with no direct findings of perforation, only 24 (16,4%) of them

    The aim of this clinical trial was to compare the effects of 2 protocols for single-phase comprehensive treatment of Class II Division 1 malocclusion (bonded Herbst followed by fixed appliances [BH + FA] vs headgear followed by fixed appliances and Class II elastics [HG + FA]) at the pubertal growth spurt. Fifty-six Class II patients were enrolled in the trial and allocated by personal choice to 2 practices, where they underwent 1 of 2 treatment protocols (28 patients were treated consecutively with BH + FA, and 28 patients were treated consecutively with HG + FA). All patients started treatment at puberty (cervical stage [CS] 3 or CS 4) and completed treatment after puberty (CS 5 or CS 6). Lateral cephalograms were taken before therapy and 6 months after the end of comprehensive therapy, with an average interval of 28 months. Longitudinal observations of a matched group of 28 subjects with untreated Class II malocclusions were compared with the 2 treated groups. Analysis of variance (ANOVA) with post-hoc tests was used for statistical comparisons. Discriminant analysis was applied to identify preferential candidates for the BH + FA protocol on the basis of profile changes (advancement of the soft tissues of the chin). The success rate (full occlusal correction of the malocclusion after treatment) was 92.8% in both treatment groups. The BH + FA group showed a significant increase in mandibular protrusion. The increase in effective mandibular length (Co-Gn) was significantly greater in both treatment groups when compared with natural growth changes in the Class II controls. Significantly greater improvement in sagittal maxillomandibular relationships was found in the BH + FA group. Retrusion of maxillary incisors and mesial movement of mandibular molars were significant in the HG + FA group. The BH + FA group showed significantly greater forward movements of soft-tissue B-point and pogonion compared with both the HG + FA and the control groups. Two pretreatment

    Most patients (75%) with Marfan syndrome present with aortic root dilatation that may require surgical intervention. However, associated cardiovascular disorders are not limited to the aortic root. These patients frequently require consecutive operations on the remaining thoracic aorta or the heart valves. Our intent was to characterize the spectrum of such procedures. Data from all patients with Marfan syndrome undergoing aortic root surgery at our centre between 1988 and 2016 were analysed retrospectively. Overall, 73 patients (26 women) were selected for the study. The median age at 1st operation was 30 years (3-68 years). Indications for aortic root surgery were aneurysm (78%) and dissection (22%). Initially, 33 Bentall procedures and 40 valve-sparing root replacement procedures were performed, with a 97% rate of follow-up completion. The median follow up was 8 years (0-28 years). Survival at 1, 10 and 15 years was 100%, 85% and 82%, respectively. During follow-up monitoring, 48 subsequent procedures were performed in 33 patients (aorta, 23; aortic valve, 11; mitral valve, 7 and combined procedures, 7). The 30-day mortality rate after subsequent procedures was 4.2%. Freedom from subsequent operation and death (combined end-point) after 5, 10 and 15 years was 70%, 53% and 34%, respectively. After the initial surgery, subsequent procedures required in the setting of Marfan syndrome most often involve the remaining native aorta, followed by the aortic and mitral valves. The continued need for additional operative procedures remains high, even decades after the initial surgeries are undertaken. Therefore, long-term patient monitoring at specialized centres is imperative.

    To evaluate the results of a consecutive series of patients affected by lumbar discogenic pain associated with facet pain and canal stenosis surgically treated with the PercuDyn device. From 2009, 129 consecutive patients (96 M, 33 F, mean age 62) were treated with posterior dynamic stabilization screws (PercuDyn). Inclusion criteria were minimum follow-up of 24 months; pain localized at the lumbar spine column alone or in association to lower limb radicular pain; magnetic resonance evidence of disc degeneration associated with facet degeneration and canal stenosis. Patients were clinically studied using VAS scale and Oswestry Disability Index (ODI); CT assessment of the neuroforamina and spinal canal areas was done at 1 month of follow-up. At 24 months of follow-up, 96 patients fulfilled the inclusion criteria. 96 intervertebral spaces were treated (85 levels L5-S1, 11 levels L4-L5). The VAS scale showed a statistically significant difference at 1 month, 6 months and 2 years with respect to the pre-operative value (p fashion (p return to daily activities. At longer follow-ups, 10 % of patients received revision surgery.

The aim of this study was to compare the outcomes of consecutive IHCA with out-of-hospital cardiac arrest (OHCA patients treated with TTM. Design, setting, and patients: Retrospectively collected data on all consecutive adult patients treated with TTM at a university tertiary heart center between 2005 and 2011 were analyzed. Measurements: Primary endpoints were survival to hospital discharge and long-term survival. Secondary endpoint was neurological outcome assessed using the Pittsburgh cerebral performance category (CPC. Results: A total of 282 patients were included in this study; 233 (83% OHCA and 49 (17% IHCA. The IHCA group presented more often with asystole, received bystander cardiopulmonary resuscitation (CPR in all cases, and had shorter time to return of spontaneous circulation (ROSC. Survival to hospital discharge was 54% for OHCA and 53% for IHCA (adjusted odds ratio 0.98 [95% confidence interval {CI}; 0.43–2.24]. Age ≤60 years, bystander CPR, time to ROSC ≤10 min, and shockable rhythm at presentation were associated with survival to hospital discharge.

    Full Text Available Identification of families at risk for ovarian cancer offers the opportunity to consider prophylactic surgery thus reducing ovarian cancer mortality. So far, identification of potentially affected families in Germany was solely performed via family history and numbers of affected family members with breast or ovarian cancer. However, neither the prevalence of deleterious variants in BRCA1/2 in ovarian cancer in Germany nor the reliability of family history as trigger for genetic counselling has ever been evaluated.Prospective counseling and germline testing of consecutive patients with primary diagnosis or with platinum-sensitive relapse of an invasive epithelial ovarian cancer. Testing included 25 candidate and established risk genes. Among these 25 genes, 16 genes (ATM, BRCA1, BRCA2, CDH1, CHEK2, MLH1, MSH2, MSH6, NBN, PMS2, PTEN, PALB2, RAD51C, RAD51D, STK11, TP53 were defined as established cancer risk genes. A positive family history was defined as at least one relative with breast cancer or ovarian cancer or breast cancer in personal history.In total, we analyzed 523 patients: 281 patients with primary diagnosis of ovarian cancer and 242 patients with relapsed disease. Median age at primary diagnosis was 58 years (range 16-93 and 406 patients (77.6% had a high-grade serous ovarian cancer. In total, 27.9% of the patients showed at least one deleterious variant in all 25 investigated genes and 26.4% in the defined 16 risk genes. Deleterious variants were most prevalent in the BRCA1 (15.5%, BRCA2 (5.5%, RAD51C (2.5% and PALB2 (1.1% genes. The prevalence of deleterious variants did not differ significantly between patients at primary diagnosis and relapse. The prevalence of deleterious variants in BRCA1/2 (and in all 16 risk genes in patients <60 years was 30.2% (33.2% versus 10.6% (18.9% in patients ≥60 years.

    Full Text Available Abstract Background Kyphoplasty represents an established minimal-invasive method for correction and augmentation of osteoporotic vertebral fractures. Reliable data on perioperative and postoperative complications are lacking in the literature. The present study was designed to evaluate the incidence and patterns of perioperative complications in order to determine the safety of this procedure for patients undergoing kyphoplasty. Patients and Methods We prospectively enrolled 102 consecutive patients (82 women and 20 men; mean age 69 with 135 operatively treated fractured vertebrae who underwent a kyphoplasty between January 2004 to June 2006. Clinical and radiological follow-up was performed for up 6 months after surgery. Results Preoperative pain levels, as determined by the visual analogous scale (VAS were 7.5 +/- 1.3. Postoperative pain levels were significantly reduced at day 1 after surgery (VAS 2.3 +/- 2.2 and at 6-month follow-up (VAS 1.4 +/- 0.9. Fresh vertebral fractures at adjacent levels were detected radiographically in 8 patients within 6 months. Two patients had a loss of reduction with subsequent sintering of the operated vertebrae and secondary spinal stenosis. Accidental cement extravasation was detected in 7 patients in the intraoperative radiographs. One patient developed a postoperative infected spondylitis at the operated level, which was treated by anterior corporectomy and 360 degrees fusion. Another patient developed a superficial wound infection which required surgical revision. Postoperative bleeding resulting in a subcutaneous haematoma evacuation was seen in one patient. Conclusion The data from the present study imply that percutaneous kyphoplasty can be associated with severe intra- and postoperative complications. This minimal-invasive surgical procedure should therefore be performed exclusively by spine surgeons who have the capability of managing perioperative complications.

    The aim of this study was to evaluate the incidence of adverse reactions to metal debris (ARMD) in a consecutive series of DUROM™ Hip Resurfacing Arthroplasty (HRA) at mid-term follow-up. Between October 2003 and March 2007 a total of 134 consecutive DUROM™ HRA in 121 patients were performed at our institution. Follow-up could be obtained in 101 unrevised patients (83%) at a mean time of 8.51 ± 0.97 years postoperatively and included patient-related outcome measurement, plain radiographs, MARS-MRI as well as whole blood metal ion assessment. 17 (16.5%) out of 103 hips revealed pseudotumour occurrence in MRI investigation, 1 (10.6%) with a diameter of ≥2 cm. Higher incidence of pseudotumours was found patients with femoral component size 7 μg/l. In contrast to cobalt determination, only elevated chromium values showed a positive association with pseudotumour occurrence and size. A significant proportion of patients developed pseudotumours and metal ion elevation in a consecutive cohort of DUROM™ HRA after mid-term follow-up. The incidence, however, seems not to differ from results of other well performing resurfacing brands; clinical relevance of our findings is unclear. Regarding potential local as well as systemic effects of metal particle release, close follow-up of patients is essential, even with clinically well-performing implants.

    This study sought to determine the prognostic value of wall motion and perfusion assessment during high-dose dobutamine stress (DS) cardiac magnetic resonance imaging (MRI) in a large patient cohort. DS-MRI offers the possibility to integrate myocardial perfusion and wall motion analysis in a single examination for the detection of coronary artery disease (CAD). A total of 1,493 consecutive patients with suspected or known CAD underwent DS-MRI, using a standard protocol in a 1.5-T magnetic resonance scanner. Wall motion and perfusion were assessed at baseline and during stress, and outcome data including cardiac death, nonfatal myocardial infarction ("hard events"), and "late" revascularization performed >90 days after the MR scans were collected during a 2 ± 1 year follow-up period. Fifty-three hard events, including 14 cardiac deaths and 39 nonfatal infarctions, occurred during the follow-up period, whereas 85 patients underwent "late" revascularization. Using multivariable regression analysis, an abnormal result for wall motion or perfusion during stress yielded the strongest independent prognostic value for both hard events and late revascularization, clearly surpassing that of clinical and baseline magnetic resonance parameters (for wall motion: adjusted hazard ratio [HR] of 5.9 [95% confidence interval (CI): 2.5 to 13.6] for hard events and of 3.1 [95% CI: 1.7 to 5.6] for late revascularization, and for perfusion: adjusted HR of 5.4 [95% CI: 2.3 to 12.9] for hard events and of 6.2 [95% CI: 3.3 to 11.3] for late revascularization, p < 0.001 for all). DS-MRI can accurately identify patients who are at increased risk for cardiac death and myocardial infarction, separating them from those with normal findings, who have very low risk for future cardiac events.

    Clinical manifestations of oligodontia consist in agenesia of multiple teeth eventually with deciduous retained teeth, atrophy of alveolar ridge, aberrations of teeth dimension, and shape, with consequent aesthetic and functional defects. The first choice treatment is based on a team collaboration of maxillo-facial surgeon, orthodontist, and prosthodontist, and is conditioned by various clinical parameters as number and site of lacking teeth, age and dental development of patients, eventual alveolar ridge atrophy. Treatment planning should be individualized for each patient. In our experience, based on 8 consecutive patients at the end of dental growth affected by oligodontia, endo-osseous fixtures positioning was carried out in consideration of long-lasting stability and optimal aesthetical characteristics. In 5 patients rehabilitative preprosthetic surgical procedures were performed, consisting in 2 sinus lift with immediate positioning of 3 fixtures in both cases, 4 heterologous bone graft in postextractive sites with retained ankylotic deciduous teeth and 1 positioning of reabsorbable biomembrane. A temporary removable denture was positioned immediately after surgery in order to obtain a prompt aesthetical and psychosocial restore. Osseointegration ratio as observed at 8.5 years follow-up was analyzed according to surgical variables and differences in prosthetic rehabilitation (fixtures supporting single crown versus multiple crowns). Successful osteointegration was observed at 8.5 years mean follow-up in 58 fixtures, corresponding to a 96.6% ratio. Failure of integration was encountered in fixtures immediately positioned in postextractive sites having a mild grade of bone atrophy, supporting single crown. A rate of success of 100% was observed in cases of immediate or delayed positioning in postextractive or traditional sites.Fixtures positioning in patients affected by isolated oligodontia, without malformative syndromes, and at the end of dental development

    In this cephalometric investigation, we analyzed the treatment effects of bone-anchored maxillary protraction (BAMP) with miniplates in the maxilla and mandible connected by Class III elastics in patients with Class III malocclusion. The treated sample consisted of 21 Class III patients consecutively treated with the BAMP protocol before the pubertal growth spurt (mean age, 11.10 ± 1.8 years) and reevaluated after BAMP therapy, about 1 year later. The treated group was compared with a matched control group of 18 untreated Class III subjects. Significant differences between the treated and control groups were assessed with independent-sample t tests (P <0.05). Sagittal measurements of the maxilla showed highly significant improvements during active treatment (about 4 mm more than the untreated controls), with significant protraction effects at orbitale and pterygomaxillare. Significant improvements of overjet and molar relationship were recorded, as well as in the mandibular skeletal measures at Point B and pogonion. Vertical skeletal changes and modifications in incisor inclination were negligible, except for a significant proclination of the mandibular incisors in the treated group. Significant soft-tissue changes reflected the underlying skeletal modifications. Compared with growth of the untreated Class III subjects, the BAMP protocol induced an average increment on skeletal and soft-tissue advancement of maxillary structures of about 4 mm, and favorable mandibular changes exceeded 2 mm.

    Full Text Available Initial 100 consecutive laparoscopic cholecystectomies performed by one surgeon were studied prospectively. The standard technique was modified in that the gallbladder removal was accomplished through the upper epigastric incision; there was no need to change the location of the camera. The conversion rate to open cholecystectomy was 2%. There were no major complications and no mortality. Minor complications occurred in 9% of the patients. Laparoscopic cholecystectomy can be performed safely in a community hospital setting. Simplified technique of gallbladder extraction is recommended.

    Current guidelines on germline mutation testing for patients suspected of having Lynch syndrome are not entirely clear in patients with tumors demonstrating isolated loss of PMS2 immunohistochemical expression. We analyzed the clinical and pathologic features of patients with tumors demonstrating isolated loss of PMS2 expression in an attempt to (1) determine the frequency of germline MLH1 and PMS2 mutations and (2) correlate mismatch-repair protein immunohistochemistry and tumor histology with germline mutation results. A total of 3213 consecutive colorectal carcinomas and 215 consecutive endometrial carcinomas were prospectively analyzed for DNA mismatch-repair protein expression by immunohistochemistry. In total, 32 tumors from 31 patients demonstrated isolated loss of PMS2 immunohistochemical expression, including 16 colorectal carcinomas and 16 endometrial carcinomas. Microsatellite instability (MSI) polymerase chain reaction was performed in 29 tumors from 28 patients with the following results: 28 tumors demonstrated high-level MSI, and 1 tumor demonstrated low-level MSI. Twenty of 31 (65%) patients in the study group had tumors demonstrating histopathology associated with high-level MSI. Seventeen patients underwent germline mutation analysis with the following results: 24% with MLH1 mutations, 35% with PMS2 mutations, 12% with PMS2 variants of undetermined significance, and 29% with no mutations in either MLH1 or PMS2. Three of the 4 patients with MLH1 germline mutations had a mutation that results in decreased stability and quantity of the MLH1 protein that compromises the MLH1-PMS2 protein complex, helping to explain the presence of immunogenic but functionally inactive MLH1 protein within the tumor. The high frequency of MLH1 germline mutations identified in our study has important implications for testing strategies in patients suspected of having Lynch syndrome and indicates that patients with tumors demonstrating isolated loss of PMS2 expression

    Enterobacteriaceae are not a frequent cause of meningitis in adults and are seen mainly in neurosurgical patients and on occasion in elderly and debilitated patients. Consequently, most series studied have been small and selected. In order to obtain a clearer clinical picture, we reviewed 20...... consecutive cases of Enterobacteriaceae meningitis admitted to the Department of Infectious Diseases, Rigshospitalet, Copenhagen, during the years 1977-97. They comprised 1.5% of all cases of acute bacterial meningitis admitted to the department. All of the patients were either elderly and/or had 1 or more......% survived with different sequelae. These high rates may, at least in part, be due to the advanced age and debilitated state of the patients studied. Escherichia coli was the most frequent of the Enterobacteriaceae....

    To develop a predictive model for the risk of high consumption of healthcare resources, and assess the ability of the model to identify complex chronic patients. A cross-sectional study was performed within a healthcare management organization by using individual data from 2 consecutive years (88,795 people). The dependent variable consisted of healthcare costs above the 95th percentile (P95), including all services provided by the organization and pharmaceutical consumption outside of the institution. The predictive variables were age, sex, morbidity-based on clinical risk groups (CRG)-and selected data from previous utilization (use of hospitalization, use of high-cost drugs in ambulatory care, pharmaceutical expenditure). A univariate descriptive analysis was performed. We constructed a logistic regression model with a 95% confidence level and analyzed sensitivity, specificity, positive predictive values (PPV), and the area under the ROC curve (AUC). Individuals incurring costs >P95 accumulated 44% of total healthcare costs and were concentrated in ACRG3 (aggregated CRG level 3) categories related to multiple chronic diseases. All variables were statistically significant except for sex. The model had a sensitivity of 48.4% (CI: 46.9%-49.8%), specificity of 97.2% (CI: 97.0%-97.3%), PPV of 46.5% (CI: 45.0%-47.9%), and an AUC of 0.897 (CI: 0.892 to 0.902). High consumption of healthcare resources is associated with complex chronic morbidity. A model based on age, morbidity, and prior utilization is able to predict high-cost risk and identify a target population requiring proactive care. Copyright © 2013 SESPAS.

    Implant-retained overdentures have been provided on both splinted and freestanding implants. For the mandible, a long history shows that both approaches can be successful over the long term. For the maxilla, many clinicians prefer to splint the implants because of concerns about softer bone quality and insufficient data supporting the use of freestanding overdenture abutments. However, a few investigations have found survival rates for unsplinted maxillary overdentures to be comparable to those for splinted ones. The present study analyzed records of consecutive patients who were treated with unsplinted maxillary and mandibular overdentures and followed for 4 to 107 months. A total of 31 overdentures were identified, 15 maxillary and 16 mandibular, supported by 129 implants. All the overdentures, along with all the implants, survived throughout the follow-up period.

    When monitoring patients over time, clinicians may struggle to distinguish 'real changes' in consecutive blood parameters from so-called natural fluctuations. In practice, they have to do so by relying on their clinical experience and intuition. We developed Labtracker+ , a medical app that calculates the probability that an increase or decrease over time in a specific blood parameter is real, given the time between measurements. We presented patient cases to 135 participants to examine whether there is a difference between medical students, residents and experienced clinicians when it comes to interpreting changes between consecutive laboratory results. Participants were asked to interpret if changes in consecutive laboratory values were likely to be 'real' or rather due to natural fluctuations. The answers of the study participants were compared with the calculated probabilities by the app Labtracker+ and the concordance rates were assessed. Medical students (n=92), medical residents from the department of internal medicine (n=19) and internists (n=24) at a Dutch University Medical Centre. Concordance rates between the study participants and the calculated probabilities by the app Labtracker+ were compared. Besides, we tested whether physicians with clinical experience scored better concordance rates with the app Labtracker+ than inexperienced clinicians. Medical residents and internists showed significantly better concordance rates with the calculated probabilities by the app Labtracker+ than medical students, regarding their interpretation of differences between consecutive laboratory results (p=0.009 and p<0.001, respectively). The app Labtracker+ could serve as a clinical decision tool in the interpretation of consecutive laboratory test results and could contribute to rapid recognition of parameter changes by physicians. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The objectives of this study are to assess: (a) the prevalence of vitamin D deficiency among new patients attending rheumatology outpatient departments, (b) the age profile of these low vitamin D patients and (c) whether any diagnostic category had a particularly high number of vitamin D-deficient patients. All new patients seen consecutively in general rheumatology clinics between January to June 2007 inclusive were eligible to partake in this study, and 231 out of 264 consented to do so. Parathyroid hormone, 25-hydroxyvitamin D, creatinine, calcium, phosphate, albumin and alkaline phosphatase levels were measured. We defined vitamin D deficiency as <\\/=53 nmol\\/l and severe deficiency as <\\/=25 nmol\\/l. Overall, 70% of 231 patients had vitamin D deficiency, and 26% had severe deficiency. Sixty-five percent of patients aged >\\/=65 and 78% of patients aged <\\/=30 years had low vitamin D levels. Vitamin D deficiency in each diagnostic category was as follows: (a) inflammatory joint diseases\\/connective tissue diseases (IJD\\/CTD), 69%; (b) soft tissue rheumatism, 77%; (c) osteoarthritis, 62%; (d) non-specific musculoskeletal back pain, 75% and (e) osteoporosis, 71%. Seasonal variation of vitamin D levels was noted in all diagnostic groups apart from IJD\\/CTD group, where the degree of vitamin D deficiency persisted from late winter to peak summer. Very high prevalence of vitamin D deficiency was noted in all diagnostic categories (p = 0.006), and it was independent of age (p = 0.297). The results suggest vitamin D deficiency as a possible modifiable risk factor in different rheumatologic conditions, and its role in IJD\\/CTD warrants further attention.

    Purpose: To provide longitudinal data on urologic morbidity after radiotherapy and brachytherapy for cervical carcinoma. Methods and Materials: Five-year longitudinal urologic morbidity data were recorded from 177 consecutive patients of median age 59 years (range: 22-86 years) with cervical carcinoma receiving radiotherapy with curative intent at the Copenhagen University Hospital, Denmark. FIGO stages (%) were as follows: Stage I (15), Stage II (30), Stage III (54), and Stage IV (1). Late morbidity was calculated as cumulative incidence based on actuarial estimates. Results: The 5-year cumulative incidence based on actuarial estimates of urologic morbidity Grades 1 + 2 + 3, Grades 2 + 3, and Grade 3 were 62%, 32%, and 5%, respectively. Frequencies of urologic morbidity in the 54 recurrence-free survivors at the end of follow-up indicated some reversibility in the case of Grades 1 and 2 morbidity. Conclusion: With the longitudinal design used in the present study, a rate of mild and moderate morbidity higher than that found in most of the previously reported literature was observed, giving cause for concern and underlining the importance of further longitudinal studies on this subject, specifically studies that relate to the background urologic morbidity in the female population, as well as to the fact that urologic morbidity might regress

    Purpose: The aim of this study was to evaluate efficacy of gynecologic examination under general anesthesia with cervical biopsies after (chemo) radiation for cervical cancer to identify patients with residual disease who may benefit from salvage surgery. Methods and Materials: In a retrospective cohort study data of all cervical cancer patients with the International Federation of Gynecology and Obstetrics (FIGO) Stage IB1 to IVA treated with (chemo) radiation between 1994 and 2001 were analyzed. Patients underwent gynecologic examination under anesthesia 8 to 10 weeks after completion of treatment. Cervical biopsy samples were taken from patients judged to be operable. In case of residual cancer, salvage surgery was performed. Results: Between 1994 and 2001, 169 consecutive cervical cancer patients received primary (chemo) radiation, of whom 4 were lost to follow-up. Median age was 56 years (interquartile range [IQR], 44-71) and median follow-up was 3.5 years (IQR, 1.5-5.9). In each of 111 patients a biopsy sample was taken, of which 90 (81%) showed no residual tumor. Vital tumor cells were found in 21 of 111 patients (19%). Salvage surgery was performed in 13 of 21 (62%) patients; of these patients, 5 (38%) achieved long-term, complete remission after salvage surgery (median follow-up, 5.2 years; range, 3.9-8.8 years). All patients with residual disease who did not undergo operation (8/21) died of progressive disease. Locoregional control was more often obtained in patients who underwent operation (7 of 13) than in patients who were not selected for salvage surgery (0 of 8 patients) (p < 0.05). Conclusions: Gynecologic examination under anesthesia 8 to 10 weeks after (chemo) radiation with cervical biopsies allows identification of those cervical cancer patients who have residual local disease, of whom a small but significant proportion may be salvaged by surgery

    To evaluate the feasibility and safety of unmonitored local anesthesia (ULA) for elective open inguinal hernia repair, we made a prospective, consecutive data collection from 1000 operations on primary and recurrent hernias. Follow-up consisted of a questionnaire 1 mo after surgery and retrieval...... from the electronic patient data management system. In 921 ASA Group I and II and 79 ASA Group III and IV patients, the median age was 60 yr (range, 18-95 yr). ULA was converted to general anesthesia in 5 of 1000 cases, and 961 patients were discharged on the day of surgery after 95 min (median...... anesthesia, day-case setup, or both, primarily because of intraoperative pain (n = 74; 7.8%). We conclude that open inguinal hernia repair can be conducted under ULA, regardless of comorbidity, with a small rate of deviation from day-case setup and minimal morbidity. It provides a safe alternative to other...

    Stefanie L De Buyser

    Full Text Available BACKGROUND: The identification of older patients at risk of poor hospital outcomes (e.g. longer hospital stay, in-hospital mortality, and institutionalisation is important to provide an effective healthcare service. OBJECTIVE: To identify factors related to older patients' clinical, nutritional, functional and socio-demographic profiles at admission to an acute care ward that can predict poor hospital outcomes. DESIGN AND SETTING: The CRiteria to assess appropriate Medication use among Elderly complex patients project was a multicentre, observational study performed in geriatric and internal medicine acute care wards of seven Italian hospitals. SUBJECTS: One thousand one hundred twenty-three consecutively admitted patients aged 65 years or older. METHODS: Hospital outcomes were length of stay, in-hospital mortality, and institutionalisation. RESULTS: Mean age of participants was 81 years, 56% were women. Median length of stay was 10 (7-14 days, 41 patients died during hospital stay and 37 were newly institutionalised. Number of drugs before admission, metastasized cancer, renal failure or dialysis, infection, falls at home during the last year, pain, and walking speed were independent predictors of LoS. Total dependency in activities of daily living and inability to perform grip strength test were independent predictors of in-hospital mortality. Malnutrition and total dependency in activities of daily living were independent predictors of institutionalisation. CONCLUSIONS: Our results confirm that not only diseases, but also multifaceted aspects of ageing such as physical function and malnutrition are strong predictors of hospital outcomes and suggest that these variables should be systematically recorded.

    2006-01-01

    Aim: To describe the preoperative magnetic resonance imaging findings of eight histologically-proven cases of hibernoma. Materials and methods: The site, size, and signal characteristics of eight consecutive hibernomas were retrospectively assessed on T1-weighted spin-echo and short T1 inversion recovery (STIR)/fat-saturated T2-weighted fast spin echo magnetic resonance images. Four patients also had gadolinium-enhanced fat-saturated T1-weighted spin echo imaging. Patient age and sex, and duration of symptoms were recorded. Results: Three female and five male patients with an average age 36 years (range 16-53 years) were included. Seven lesions occurred in the thigh, four in the anterior compartment and three in the posterior compartment. One lesion occurred superficial to the scapula. All cases demonstrated common magnetic resonance imaging findings of a well-defined, heterogeneous mass, slightly or clearly hypo-intense to subcutaneous fat on T1-weighted spin-echo images, with prominent thin low signal bands throughout the tumour. The lesions failed to fully suppress on STIR or fat-saturated T2-weighted images. Only one of the four contrast-enhanced studies demonstrated increased vascularity in the tumour. Conclusion: The MRI findings of a lesion that is diffusely slightly hypointense to surrounding subcutaneous fat, should prompt the operator to consider hibernoma in the differential diagnosis

    The optimal management of craniopharyngioma is still controversial. The aim of this study is to explore microsurgical outcomes of craniopharyngioma in 335 cases. Clinical data of 335 consecutive patients with craniopharyngioma between March 2011 and March 2017 were retrospectively analyzed. Gross total resection (GTR) was achieved in 265 cases (79.1%), subtotal resection (STR) was obtained in 70 cases (20.9%). The GTR rate was 81.93% in pediatric group and 78.17% in adult group respectively, no significant difference regarding the GTR rate was found in adult group compared with in pediatric group (p > 0.05). However, there was a noticeable difference in the elevated hypothalamic obesity in children group compared with in adult group after operation (p  0.05). Additionally, there were no statistically significant differences for recurrence-free curves between GTR and STR plus adjuvant radiotherapy (p > 0.05). Present findings demonstrated that tumor recurrence and surgical times contribute to negative total resection for craniopharyngioma. Postoperative precise adjuvant radiotherapy was considered in selected cases if pursuit of GTR was rather dangerous under disadvantageous removal factors. Copyright © 2018 Elsevier B.V.

    During 26 months 200 consecutive patients with fracture of the bony pelvis were evaluated and treated for urological injury. There was no correlation between the extent of pelvic injury and degree of hematuria but hematuria was present in all patients with a urological injury. All urological injuries occurred with anterior arch fractures. The over-all incidence of injury was 13.5 per cent (bladder 9 per cent, urethra 3.5 per cent and combined 1 per cent). Limited extraperitoneal bladder ruptures were treated successfully by Foley catheter drainage.

However, a normal liver stiffness could rule out hepatic causes of ascites at an early stage. The aim of the present study was to determine whether liver stiffness can be generally determined by transient elastography through an ascites layer, to determine whether the ascites-mediated increase in intra-abdominal pressure affects liver stiffness, and to provide initial data from a pilot cohort of patients with various causes of ascites.Methods and results: Using the XL probe in an artificial ascites model, we demonstrated (copolymer phantoms surrounded by water that a transient elastography-generated shear wave allows accurate determination of phantom stiffness up to a water lamella of 20 mm. We next showed in an animal ascites model that increased intra-abdominal pressure does not affect liver stiffness. Liver stiffness was then determined in 24 consecutive patients with ascites due to hepatic (n = 18 or nonhepatic (n = 6 causes. The cause of ascites was eventually clarified using routine clinical, imaging, laboratory, and other tools. Valid (75% or acceptable (25% liver stiffness data could be obtained in 23 patients (95.8% with ascites up to an ascites lamella of 39 mm.

    The diagnosis of combined allergic and irritant contact dermatitis is an accepted subdiagnosis for hand dermatitis, and it is often considered in a patient with contact dermatitis, a positive and relevant patch test result, and wet work exposure. We therefore hypothesize that it is arbitrary for wet work exposure to be taken into consideration in a patient with newly diagnosed relevant contact allergy. Furthermore, an overestimation of the diagnosis will probably occur if the criteria for wet work exposure are applied correctly, as many occupations have an element of wet work. To find the statistically expected number of combined allergic and irritant contact dermatitis cases in 1000 patients, and to evaluate the diagnostic criteria for the diagnosis. One thousand consecutive patients with occupational contact dermatitis from a hospital unit in Denmark were assessed. The expected number of cases with the diagnosis of combined allergic and irritant contact dermatitis was 0.33%, as compared with the observed number of 6.4%. Females occupied in wet occupations were often diagnosed with combined allergic and irritant contact dermatitis (p contact dermatitis should be used critically to avoid misclassification, and possible criteria for the diagnosis are proposed. © 2014 John Wiley & Sons A/S.

    Purpose: To determine if use of an electromagnetic navigation system (EMN) decreases radiation dose and procedure time of CT fluoroscopy guided lung biopsy in lesions smaller than 2.5 cm. Materials/methods: 86 consecutive patients with small lung masses (<2.5 cm) were approached. 60 consented and were randomized to undergo biopsy with CT fluoroscopy (CTF) (34 patients) or EMN (26 patients). Technical failure required conversion to CTF in 8/26 EMN patients; 18 patients completed biopsy with EMN. Numerous biopsy parameters were compared as described below. Results: Average fluoroscopy time using CTF was 28.2 s compared to 35.0 s for EMN (p = 0.1). Average radiation dose was 117 mGy using CTF and 123 mGy for EMN (p = 0.7). Average number of needle repositions was 3.7 for CTF and 4.4 for EMN (p = 0.4). Average procedure time was 15 min for CTF and 20 min for EMN (p = 0.01). There were 7 pneumothoracesin the CTF group and 6 pneumothoraces in the EMN group (p = 0.7). One pneumothorax in the CTF group and 3 pneumothoraces in the EMN group required chest tube placement (p = 0.1). One pneumothorax patient in each group required hospital admission. Diagnostic specimens were obtained in 31/34 patients in the CTF group and 22/26 patients in the EMN group (p = 0.4). Conclusions: EMN was not statistically different than CTF for fluoroscopy time, radiation dose, number of needle repositions, incidence of pneumothorax, need for chest tube, or diagnostic yield. Procedure time was increased with EMN.

    This paper extends the linear multi-state consecutively-connected system (LMCCS) to the case of LMCCS-MN, where MN denotes the dual constraints of m consecutive gaps and n total gaps. All the nodes are distributed along a line and form a sequence. The distances between the adjacent nodes are usually non-uniform. The nodes except the last one can contain statistically independent multi-state connection elements (MCEs). Each MCE can provide a connection between the node at which it is located and the next nodes along the sequence. The LMCCS-MN fails if it meets either of the two constraints. The universal generating function technique is adopted to evaluate the system reliability. The optimal allocations of LMCCS-MN with two different types of failures are solved by genetic algorithm. Finally, two examples are given for the demonstration of the proposed model. - Highlights: • A new model of multi-state consecutively-connected system (LMCCS-MN) is proposed. • The non-uniform distributed nodes are involved in the proposed LMCCS-MN model. • An algorithm for system reliability evaluation is provided by the UGF method. • The computational complexity of the proposed algorithm is discussed in detail. • Optimal element allocation problem is formulated and solved.

    Laparoscopic anti-reflux surgery is conventionally performed using two 10/12 mm ports. While laparoscopic procedures reduce post-operative pain, the use of larger ports invariably increases discomfort and affects cosmesis. We describe a new all 5 mm ports technique for laparoscopic anti-reflux surgery and present a review of our initial experience with this approach. All patients undergoing laparoscopic fundoplication over a 35 month period from February 2013 under the care of a single surgeon were included. A Lind laparoscopic fundoplication was performed using an all 5 mm port technique. Data was recorded prospectively on patient demographics, operating surgeon, surgical time, date of discharge, readmissions, complications, need for re-intervention, and reasons for admission. Two hundred and five consecutive patients underwent laparoscopic fundoplication over the study period. The all 5 mm port technique was used in all cases, with conversion to a 12 mm port only once (0.49%). Median operating time was 52 min 185 (90.2%) patients were discharged as day cases. Increasing ASA grade and the presence of a hiatus hernia were associated with the need for overnight stay with admission required in 33% of patients with ASA 3, compared to 4% with ASA 1 (p = 0.001), and 29% of those with a hiatus hernia vs. 5% without (p management. This would improve the service for these patients and culminate in cost savings for the NHS. Copyright © 2016. Published by Elsevier Ltd.

    To determine if the rate of major discrepancies between resident preliminary reports and faculty final reports increases during the final hours of consecutive 12-hour overnight call shifts. Institutional review board exemption status was obtained for this study. All overnight radiology reports interpreted by residents on-call between January 2010 and June 2010 were reviewed by board-certified faculty and categorized as major discrepancies if they contained a change in interpretation with the potential to impact patient management or outcome. Initial determination of a major discrepancy was at the discretion of individual faculty radiologists based on this general definition. Studies categorized as major discrepancies were secondarily reviewed by the residency program director (M.H.S.) to ensure consistent application of the major discrepancy designation. Multiple variables associated with each report were collected and analyzed, including the time of preliminary interpretation, time into shift study was interpreted, volume of studies interpreted during each shift, day of the week, patient location (inpatient or emergency department), block of shift (2-hour blocks for 12-hour shifts), imaging modality, patient age and gender, resident identification, and faculty identification. Univariate risk factor analysis was performed to determine the optimal data format of each variable (ie, continuous versus categorical). A multivariate logistic regression model was then constructed to account for confounding between variables and identify independent risk factors for major discrepancies. We analyzed 8062 preliminary resident reports with 79 major discrepancies (1.0%). There was a statistically significant increase in major discrepancy rate during the final 2 hours of consecutive 12-hour call shifts. Multivariate analysis confirmed that interpretation during the last 2 hours of 12-hour call shifts (odds ratio (OR) 1.94, 95% confidence interval (CI) 1.18-3.21), cross

    Lateral ankle sprains are a common injury that typically respond well to nonoperative therapy. When nonoperative therapy fails and patients develop chronic lateral ankle instability, they become candidates for surgical repair. The present study examined 45 consecutive patients (45 ankles) with chronic lateral ankle instability who underwent arthroscopic Broström repair using a double-row suture anchor construct. The 45 patients (27 females and 18 males) were followed up for a mean of 14 (range 12 to 20) months. The mean time to weightbearing with crutches was 3.3 (range 2 to 4) days, and full weightbearing was initiated at a mean of 14.4 (range 12 to 16) days. All patients participated in structured physical therapy, which was started at 21.6 (range 18 to 23) days. Patients were transitioned to regular shoe gear with a stirrup-style ankle brace at 28.7 (range 26 to 31) days. The American Orthopaedic Foot and Ankle Society scale scores improved from an average preoperative score of 48.7 (range 45 to 55) to 95.4 (range 90 to 100) postoperatively. The average visual analog scale decreased from 8 (range 6 to 10) preoperatively to 0.6 (range 0 to 5) postoperatively at the last follow-up visit. The Karlsson-Peterson score postoperatively was 87 of 100. We have shown that patients with this new arthroscopic Broström technique modified with a proximal suture anchor can begin weightbearing earlier than previously reported, without adverse effects in terms of pain, functional outcomes scores, and clinical outcomes.

    The prevalence and clinical characteristics of IgG4-related hypophysitis remain unclear due to the limited number of case reports. Therefore, in this study, we screened consecutive outpatients with hypopituitarism and/or diabetes insipidus (DI) to estimate its prevalence. A total of 170 consecutive outpatients with hypopituitarism and/or central DI were screened at Kobe University Hospital for detecting IgG4-related hypophysitis by pituitary magnetic resonance imaging, measuring serum IgG4 concentrations, assessing the involvement of other organs, and carrying out an immunohistochemical analysis to detect IgG4-positive cell infiltration. Among the screened cases, 116 cases were excluded due to diagnosis of other causes such as tumors and congenital abnormalities. Additionally, 22 cases with isolated ACTH deficiency were analyzed and were found not to meet the criteria of IgG4-related hypophysitis. The remaining 32 cases were screened and seven were diagnosed with IgG4-related hypophysitis, of which three cases were diagnosed by analyzing pituitary specimens. IgG4-related hypophysitis was detected in 30% (seven of 23 patients) of hypophysitis cases and 4% of all hypopituitarism/DI cases. The mean age at the onset of IgG4-related hypophysitis was 61.8±8.8 years, and the serum IgG4 concentration was 191.1±78.3 mg/dl (normal values 5-105 mg/dl and values in IgG4-related disease (RD) ≥135 mg/dl). Pituitary gland and/or stalk swelling was observed in six patients, and an empty sella was observed in one patient. Multiple co-existing organ involvement was observed in four of the seven patients prior to the onset of IgG4-related hypophysitis. These data suggest that the prevalence of IgG4-related hypophysitis has been underestimated. We should also consider the possibility of the development of hypopituitarism/DI caused by IgG4-related hypophysitis during the clinical course of other IgG4-RDs.

    Side-by-side analysis of CT and conventional 18 FDG-PET in oncological imaging is well established. Aim of this study was to find out which patients or diagnostic groups may benefit the most from the newly introduced integrated PET/CT scanners. Patients, methods: 407 consecutively admitted oncological patients with accompanying CT (groups A-D) and 326 patients without CT (groups E-G) were examined by conventional ring PET. Two nuclear medicine physicians and two radiologists assessed each patient's PET and CT scans for pathological lesions with regard to localisation and infiltration of adjacent anatomical structures. Patients without pathological PET findings were assigned to groups A (with CT) or E (without CT). If the localisation and/or extent of a pathological PET focus could only be assessed by taking into account the CT scan, the patient was assigned to group C (with CT) or G (without CT). If PET alone was sufficient for both questions the patient was assigned to groups B (with CT) or F (without CT). If neither method allowed for a precise lesion characterisation, the patient was assigned to group D. Results: 38.6% (A, E) of all patients were PET-negative. PET alone sufficed in 20.6% (B, F). Side-by-side reading of PET and CT was needed for 43.5% (C) of patients referred to PET with a current CT. Side-by-side reading of CT and PET did not suffice for 7.3% (D) of patients in that cohort. A total of 28.2% (G) of the cases without CT would have profited from it. The most frequent oncological diagnoses in group D (PET and conventional CT not sufficient) were bronchial carcinoma with abdominal lesions, while in group G (without CT but CT required) head/neck cancer with thoracic lesions was predominant. Conclusions: Side-by-side reading of PET and already existing conventional CT failed to yield conclusive data with regard to lesion characterisation in only 7.4% of patients so that PET/CT might have been helpful in these cases. 28.2% of the patients without

    Acute cholecystitis is one of the most frequent abdominal inflammatory processes. If untreated or misdiagnosed it can result in severe complications such as gallbladder rupture, abscesses, or peritonitis. It was retrospectively reviewed a series of 71 consecutive patients with surgical confirmation of acute cholecystitis and then compared the results of the diagnostic techniques that have been used preoperatively. Over 16 months, 71 consecutive patients (42 women and 29 men; age range: 34-84 years, mean: 58) with acute abdominal pain were operated on for acute cholecystitis at Cardarelli Hospital, Naples. On abdominal plain films, it was retrospectively searched the following signs: densities projected over the gallbladder, linear calcifications in gallbladder walls, gallbladder enlargement, focal gas collections within the gallbladder, and air-fluid levels in the gallbladder wall lumen. On US images it has been looked for: gallbladder wall thickening (>3 mm), intraluminal content in the gallbladder, pericholecystic fluid, US Murphy's sign, and gallbladder distension. On CT images, it has been investigated: gallbladder distensions, wall thickening, intraluminal content, pericholecystic fluid, and inflammatory changes in pericholecystic fat. On plain abdominal films it was found densities projected over the gallbladder (16.9%) and linear calcifications in the gallbladder wall (4.6%). US appears to be the most useful imaging technique in patients with suspected acute cholecystitis, for both screening and final diagnosis. CT plays a limited role in the early assessment of these patients, but can a useful tool in diagnosing acute cholecystitis in patients with questionable physical findings or in investigating related complications.

    Eighteen consecutive patients with adult-onset intradural spinal teratoma underwent surgical treatment in our center from 1998 to 2013. Teratoma is defined as a neoplasm composed of elements derived from three germ cell layers (ectoderm, endoderm and mesoderm). Intraspinal teratoma is extremely rare and accounts for 0.2-0.5% of all spinal cord tumors. Moreover, teratoma occurs primarily in neonates and young children. Adult-onset intradural spinal teratoma is even rare. The aim of this study was to discuss the clinical characteristics, diagnosis and therapeutic strategies of adult-onset intradural spinal teratoma. This retrospective study included 18 consecutive adult patients with intradural teratoma who were surgically treated in our center between 1998 and 2013. The clinical features, pathogenesis, diagnostic strategies and surgical outcomes were discussed. Neurological function outcomes were evaluated by the JOA scoring system. Of the 18 included patients, 4 patients received subtotal resection and the other 14 patients received total resection. All the 18 cases were diagnosed with mature teratoma. The mean follow-up period was 79.7 (median 60.5; range 27-208) months. Local recurrence occurred in two of the four patients who underwent subtotal resection and in no patient who underwent total resection. The neurologic status improved in 16 cases and remained unchanged in the other two patients. Adult-onset intradural spinal teratoma is extremely rare. To the best of our knowledge, this is the largest series of patients with this disease. Despite the slow-growth and indolent nature, radical resection remains the recommended treatment to reduce tumor recurrence.

    There are limited data on serum total light chain (sTLC) in lymphoma and its relative role on the outcome of diffuse large B cell lymphoma (DLBCL) patients. Blood samples from 46 cases newly diagnosed with DLBCL were collected consecutively during chemotherapy to detect sTLC, IgG, IgA, and IgM levels. Clinical data and survival outcomes were analyzed according to the results of sTLC measurements. In summary, 22 patients (47.8 %) had abnormal k or λ light chain, respectively, and 6 patients (13.0 %) had both abnormal k and λ light chains before chemotherapy. Patients with elevated k light chain more frequently displayed multiple extra-nodal organ involvement (P = 0.01) and had an inferior overall survival (OS) (P = 0.041) and progression-free survival (PFS) (P = 0.044) compared to patients with normal level of k light chain. Furthermore, patients with elevated level of both k and λ also exhibited significant association with shorter OS (P = 0.002) and PFS (P = 0.009). Both elevated k alone and concurrent elevated k and λ had independent adverse effects on PFS (P = 0.031 and P = 0.019, respectively). sTLC level was reduced gradually by treatment in this study and reached the lowest point after the fourth cycle of chemotherapy, which was consistent with the disease behavior during chemotherapy. Considering the small sample size of this study, these results should be confirmed in a larger prospective study.

    Objectives: Late recognition of lung cancer is the major factor contributing towards its unsuccessful treatment. We conducted a prospective study to define any significant relationship of presenting symptoms with the diagnosis of lung cancer with a view to develop a model to identify those at high risk. Methods: A consecutive series of 587 patients referred to our rapid access chest clinic with the suspicion of lung cancer were included. The presenting symptoms, chest x-ray findings and final diagnosis of all the patients were recorded. Chi-square and t-test were used for univariate analysis. A model was generated from logistic regression analysis and the discriminatory power of the model was assessed using area under receiver operator characteristic curve. Results: Univariate analysis demonstrated that smoking, anorexia, weight loss and voice change were significantly more common in patients with lung cancer (p<0.05). Cough, expectoration and hemoptysis were significantly less common (p<0.05). Regression analysis qualified age, weight loss and smoking as significant predictors of lung cancer. Conclusion: Only few of the historically accepted symptoms demonstrated a strong association with lung cancer and the model developed on these can form basis for a scoring tool that can perhaps help identify those at higher risk of cancer. Further refinement of the tool is required to accommodate cases presenting at primary care level. (author)

    Objectives: To investigate the diagnostic accuracy of 64-slice multidetector computed tomography (64-CT) for detection of in-stent restenosis (ISR) in an unselected, consecutive patient population. Background: Detection of in-stent restenosis by cardiac CT would be a major advance for the evaluation of patients suspected of having ISR. However, the diagnostic accuracy of current generation 64-CT in this context is not fully established. Methods: We conducted a prospective study on patients with stable angina or acute coronary syndrome with no prior history of coronary artery disease. Six months after percutaneous coronary intervention (PCI) with stent placement they underwent a 64-CT scan (Toshiba Multi-Slice Aquilion 64) and consequently a repeat coronary angiography for comparison. Cardiac CT data sets were analyzed for the presence of in-stent restenosis by two independent expert readers blinded to the coronary angiographic data. Results: Ninety-three patients with a total of 140 stents were evaluated. Males comprised 82% of the study group and the mean age was 63 {+-} 10 years. The mean time from PCI to the repeat coronary angiography was 208 {+-} 37 days and the mean time from 64-CT to repeat coronary angiography was 3.7 {+-} 4.9 days. The restenosis rate according to coronary angiography was 26%. Stent diameter, strut thickness, heart rate and body mass index (BMI) significantly affected image quality. The sensitivity, specificity, positive and negative predictive values of 64-CT for detection of in-stent restenosis were 27%, 95%, 67% and 78%, respectively. Conclusions: Current generation, 64-slice CT, remains limited in its ability to accurately detect in-stent restenosis.

    Robotic technology is increasingly prevalent in bariatric surgery, yet there are national deficiencies in exposure of surgical residents to robotic techniques. The purpose of this study is to accurately characterize the perioperative outcomes of a resident teaching model using the robotic-assisted sleeve gastrectomy. University Hospital. We identified 411 consecutive patients who underwent robotic sleeve gastrectomy at our institution from a prospectively maintained administrative database. Perioperative morbidity, operative time, and supply cost of the procedure were analyzed. Mean operative time was 96.4±24.9 minutes; mean robot usage time was 63.9 minutes (range 30.0-122.0 min). Ninety-day morbidities included reoperation (0.72%), major bleeding complications (0.48%), staple line leak (0.24%), stricture (0.97%), need for blood transfusion (3.86%), surgical site infection (1.69%), deep vein thrombosis (0.48%), and pulmonary embolism (0.48%). Mortality was nil. The resident cohort achieved operative time plateaus after five consecutive cases. Subset analysis for fiscal year 2014 demonstrated significantly increased supply cost for robotic sleeve gastrectomy compared with its laparoscopic equivalent. Robotic-assisted sleeve gastrectomy can be instituted as a model for resident robotic education with rates of morbidity and operative times equivalent to historical laparoscopic controls. The robot's enhanced ergonomics and its opportunity for resident education must be weighed against its increased supply cost. Copyright © 2016 American Society for Bariatric Surgery.

  3. Common Lung Microbiome Identified among Mechanically Ventilated Surgical Patients.

    Directory of Open Access Journals (Sweden)

    Ashley D Smith

    Full Text Available The examination of the pulmonary microbiome in patients with non-chronic disease states has not been extensively examined. Traditional culture based screening methods are often unable to identify bacteria from bronchoalveolar lavage samples. The advancement of next-generation sequencing technologies allows for a culture-independent molecular based analysis to determine the microbial composition in the lung of this patient population. For this study, the Ion Torrent PGM system was used to assess the microbial complexity of culture negative bronchoalveolar lavage samples. A group of samples were identified that all displayed high diversity and similar relative abundance of bacteria. This group consisted of Hydrogenophaga, unclassified Bacteroidetes, Pedobacter, Thauera, and Acinetobacter. These bacteria may be representative of a common non-pathogenic pulmonary microbiome associated within this population of patients.

    Schwannoma of the cervical vagus nerve is rare. Treatment options include intracapsular enucleation and en bloc resection. The purpose of this study was to compare the outcomes of enucleation and resection in terms of postoperative mortality and morbidity, freedom from vocal cord palsy, freedom from local recurrence, quality-adjusted life-year (QALY) and vocal handicap index (VHI). Twentytwo consecutive patients were divided into two groups. Patients in group A (n = 9) underwent intracapsular enucleation, whereas patients in Group B (n = 13) underwent en bloc resection. Main endpoints of the study were postoperative mortality and morbidity, freedom from vocal cord palsy, freedom from local recurrence and quality of life. The quality of life after surgery was assessed according to the quality-adjusted life-year (QALY) EQ-5D-5L methodology, and calculation of the voice handicap index (VHI). Postoperative mortality was nil. Morbidity included 1 wound dehiscence in group A and 2 transitory dysphagias in group B. Freedom from vocal cord palsy was 22% in group A and zero in group B (p = 0.15). Operation-specific local recurrence rate was 33% (3/9 patients) in group A and nil in group B (0/23 patients) (p = 0.05). QALYs was 0.55 in group A and 0.54 in group B (p = 1.0). VHI was 23.77 in group A and 26.15 in group B (p = 1.00). Resection is superior to enucleation in terms of freedom from local recurrence. Functional results are comparable for both techniques.

    Qualitative research aimed at identifying patient acceptance of active surveillance (AS) has been identified as a public health research priority. The primary objective of this study was to determine if analysis of a large-sample of anonymous internet conversations (ICs) could be utilized to identify unmet public needs regarding AS. English-language ICs regarding prostate cancer (PC) treatment with AS from 2002-12 were identified using a novel internet search methodology. Web spiders were developed to mine, aggregate, and analyze content from the world-wide-web for ICs centered on AS. Collection of ICs was not restricted to any specific geographic region of origin. NLP was used to evaluate content and perform a sentiment analysis. Conversations were scored as positive, negative, or neutral. A sentiment index (SI) was subsequently calculated according to the following formula to compare temporal trends in public sentiment towards AS: [(# Positive IC/#Total IC)-(#Negative IC/#Total IC) x 100]. A total of 464 ICs were identified. Sentiment increased from -13 to +2 over the study period. The increase sentiment has been driven by increased patient emphasis on quality-of-life factors and endorsement of AS by national medical organizations. Unmet needs identified in these ICs include: a gap between quantitative data regarding long-term outcomes with AS vs. conventional treatments, desire for treatment information from an unbiased specialist, and absence of public role models managed with AS. This study demonstrates the potential utility of online patient communications to provide insight into patient preferences and decision-making. Based on our findings, we recommend that multidisciplinary clinics consider including an unbiased specialist to present treatment options and that future decision tools for AS include quantitative data regarding outcomes after AS.

    BACKGROUND: Heterogeneity in patients with low back pain (LBP) is well recognised and different approaches to subgrouping have been proposed. Latent Class Analysis (LCA) is a statistical technique that is increasingly being used to identify subgroups based on patient characteristics. However......, as LBP is a complex multi-domain condition, the optimal approach when using LCA is unknown. Therefore, this paper describes the exploration of two approaches to LCA that may help improve the identification of clinically relevant and interpretable LBP subgroups. METHODS: From 928 LBP patients consulting...... of statistical performance measures, qualitative evaluation of clinical interpretability (face validity) and a subgroup membership comparison. RESULTS: For the single-stage LCA, a model solution with seven patient subgroups was preferred, and for the two-stage LCA, a nine patient subgroup model. Both approaches...

    The aim of this study was to determine the potential diagnostic value of regional myocardial adrenergic {sup 123}I-metaiodobenzylguanidine (MIBG) single photon emission computed tomography (SPECT) imaging to identify patients with Lewy body diseases (LBD+). Sixty-four consecutive patients who underwent cardiac {sup 123}I-MIBG SPECT to differentiate LBD+, including Parkinson's disease (PD) and dementia with Lewy bodies (DLB), from patients without LBD (LBD-) were retrospectively reviewed. A neurologist expert in memory disorders determined the final clinical diagnosis by using international clinical diagnostic criteria. Planar [heart to mediastinum ratio (HMR)] and {sup 123}I-MIBG SPECT[innervation defect score (IDS)] using the 17-segment left ventricular model (five-point scale) were obtained 4 h after the injection of {sup 123}I-MIBG on a low-energy high-resolution (LEHR) collimator. Receiver-operating characteristic (ROC) analysis was performed to determine the optimal HMR and IDS cut-off values to discriminate LBD+ from LBD-. Of the 64 patients, 45 (70 %) were diagnosed LBD+ (DLB, n = 27; PD, n = 18) and 19 were diagnosed LBD- (5 other dementias, 14 other parkinsonisms). The HMR and IDS of LBD+ were significantly different from those of LBD- (1.30 ± 0.21 vs 1.65 ± 0.26, p < 0.001; 39 ± 28 vs 8 ± 16, p = 0.001). The optimal HMR and IDS cut-off values to discriminate LBD+ (n = 45) from LBD- (n = 19) were 1.47 and 6/68, providing a sensitivity and specificity of 82.2 and 84.2 % and 86.7 and 73.7 %, respectively. Regional myocardial adrenergic {sup 123}I-MIBG imaging SPECT has a potential diagnostic value to identify LBD+. (orig.)

    Purpose To assess the incidence of costal cartilage (CC) fractures in whole-body computed tomographic (CT) examinations for blunt trauma and to evaluate distribution of CC fractures, concomitant injuries, mechanism of injury, accuracy of reporting, and the effect on 30-day mortality. Materials and Methods Institutional review board approval was obtained for this retrospective study. All whole-body CT examinations for blunt trauma over 36 months were reviewed retrospectively and chest trauma CT studies were evaluated by a second reader. Of 1461 patients who underwent a whole-body CT examination, 39% (574 of 1461) had signs of thoracic injuries (men, 74.0% [425 of 574]; mean age, 46.6 years; women, 26.0% [149 of 574]; mean age, 48.9 years). χ 2 and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Interobserver agreement was calculated by using Cohen kappa values. Results A total of 114 patients (men, 86.8% [99 of 114]; mean age, 48.6 years; women, 13.2% [15 of 114]; mean age, 45.1 years) had 221 CC fractures. The incidence was 7.8% (114 of 1461) in all whole-body CT examinations and 19.9% (114 of 574) in patients with thoracic trauma. Cartilage of rib 7 (21.3%, 47 of 221) was most commonly injured. Bilateral multiple consecutive rib fractures occurred in 36% (41 of 114) versus 14% (64 of 460) in other patients with chest trauma (OR, 3.48; 95% CI: 2.18, 5.53; P chest trauma with CC fractures (13%, 15 of 114) versus patients with chest trauma without CC fractures (4%, 18 of 460) (OR, 3.72; 95% CI: 1.81, 7.64; P = .0001), as well as aortic injuries (n = 4 vs n = 0; P = .0015; OR, unavailable). Kappa value for interobserver agreement in detecting CC fractures was 0.65 (substantial agreement). CC fractures were documented in 39.5% (45 of 114) of primary reports. The 30-day mortality of patients with CC fractures was 7.02% (eight of 114) versus 4.78% (22 of 460) of other patients with chest trauma (OR, 1.50; 95% CI: 0.65, 3.47; P = .3371). Conclusion

    This study explores variables associated with poor prognosis in postoperative p16 positive oropharyngeal squamous cell carcinoma (OPSCC) patients undergoing adjuvant radiotherapy or chemoradiotherapy. Specifically, analysis was done related to timing of feeding tube insertion relative to radiotherapy. From 1997-2009, of 376 consecutive patients with OPSCC, 220 received adjuvant IMRT, and 97 were p16 positive and eligible. Of these, 23 had feeding tube placement before IMRT (B-FT), 32 during/after IMRT (DA-FT), and 42 had no feeding tube (NO-FT). Feeding tubes were not placed prophylactically. These three groups were analyzed for differential tumor, patient, treatment, and feeding tube characteristics, as well as differences in overall survival (OS), disease free survival (DFS), and distant metastasis free survival (DMFS). Pre-RT FT insertion was associated with higher tumor size and depth, T (but not N) and overall stage, comorbidities, presence of chemotherapy, and less use of transoral laser microsurgery/transoral bovie. Additionally, time from surgery to IMRT completion was also statistically longer in the B-FT group. The feeding tube was permanent in 52% of patients in the B-FT group versus 16% in the DA-FT group (p = 0.0075). The 5-year OS for the NO-FT, DA-FT, and B-FT groups was 90%, 86%, and 50%, respectively. The 5-year DFS for the NO-FT, DA-FT, and B-FT groups was 87.6%, 83.6%, and 42.7%, respectively. Multivariate analysis showed that for OS and DFS, feeding tube placement timing and smoking history were statistically significant. Due to the poor prognosis of early FT insertion, the presence of FTs at time of radiotherapy consultation can be used as an alternate marker to identify a subset of p16 positive OPSCC patients that have a poor prognosis.

    Forty-two consecutive patients received emergency treatment for acute mitral insufficiency causing pulmonary edema between 1984 and 1992. The underlying diagnoses were acute myocardial infarction (n = 21), acute bacterial endocarditis on the native mitral valve (n = 9), prosthetic endocarditis in the mitral position (n = 4), acute failure of a replacement valve (n = 5), blunt chest trauma (n = 1) and chordal rupture in Marfan's syndrome (n = 2). Dysfunction of the subvalvular apparatus was present in 24 patients, verified by transthoracic echocardiography in 18 (75%) and by transoesophageal echocardiography in all patients in whom this technique was used. There were four cases of outflow strut fracture of a Björk-Shiley mitral prosthesis; a reliable diagnosis was made by fluoroscopy in all patients. Bedside hemodynamic monitoring was found to be unreliable both for differential diagnosis and for the quantitative assessment of the degree of mitral insufficiency. The right ventricular filling pressure was normal in 32/39 patients (82%), and the pulmonary artery and pulmonary capillary pressures elevated in 37/39 (95%). Diagnostically important, high pulmonary capillary v-waves were documented in 13 patients (33%). The left ventricular impedance could be influenced with sodium nitroprussid combined in some cases with dobutamin, and the resultant decrease of the peripheral vascular resistance from 1480 +/- 222 to 702 +/- 86 dyn x sec x cm-5 was followed by a proportionate reduction in the transmitral regurgitant fraction. Three patients died prior to the intended emergency surgical intervention. Emergency surgery was completed in 21 patients with an early mortality of 23.8% (n = 5). Ten patients underwent elective surgery within, and another three later than one year from the onset of the acute symptoms with an early mortality of 7.7% (n = 1). Four patients are alive and clinically well with medical treatment alone.

    Preoperative estimates of cognitive and seizure outcome must be as accurate as possible if the candidate is to make an informed decision about epilepsy surgery. Significant declines in memory function are reported in approximately 30% of temporal lobe surgery patients. The percentage varies according to the ways in which a postoperative deterioration is defined but since the majority of outcome studies do not take into account the patient's capacity to deteriorate if they are functioning at or close to the floor of a memory test prior to surgery, the published percentages may be an underrepresentation of the true extent of memory decline following epilepsy surgery. We examined the cognitive 'cost' of epilepsy surgery in a consecutive series of 474 patients who underwent elective surgery for medically intractable epilepsy. All patients underwent a presurgical assessment prior to and 1year after the surgery. Reliable change indices were used to identify significant postoperative memory decline. Postoperative outcome was dichotomized using the ILAE 2008 classification. All patients in class one were classified as seizure-free (67.5% of the sample). Excluding patients already functioning at or below the 2nd percentile on standardized memory tests, 37.8% experienced a significant postoperative decline in memory function. Twelve percent experienced the 'double hit' of significant postoperative memory decline and ongoing seizures following surgery. Patients with pathologies other than hippocampal sclerosis and with signs of limited cognitive reserve, both in terms of memory function and overall intellectual ability were most likely to suffer a double hit. Our results indicate that caution should be exercised when operating on these patients and preoperative counseling should be tailored to reflect the likely risk/benefit ratio of a temporal lobe resection for medically intractable epilepsy in this group.

    Ischaemic stroke clinical outcomes are improved by earlier treatment with intravenous thrombolysis. An existing pathway at the Mater University Hospital for assessment of suspected acute stroke in the Emergency Department was updated, aiming to shorten ‘door to needle time’. This study examines the final clinical diagnosis of Dublin Fire Brigade Ambulance Paramedic identified Face Arm Speech Test (FAST) positive patients presenting to the Emergency Department over a 7 month period. A retrospective analysis was carried out of 177 consecutive FAST positive patients presenting between March and November 2014. The final clinical diagnosis was acute stroke in 57.1% (n=101) of patients. Of these, 76 were ischaemic strokes of whom 56.5% (n=43) were thrombolysed. In the pre-hospital setting Ambulance Paramedics can identify, with reasonable accuracy, acute stroke using the FAST test. Over half of the ischaemic stroke patients presenting via this pathway can be treated with intravenous thrombolysis

    To assess feasibility and toxicity of Helical TomoTherapy® for treating anal cancer patients. From 2007 to 2011, 64 patients were consecutively treated with TomoTherapy® in three centres for locally advanced squamous-cell anal carcinoma (T2 > 4 cm or N positive). Prescribed doses were 45 Gy to the pelvis including inguinal nodes and 59.4 Gy to the primary site and involved nodes with fractions of 1.8 Gy, five days a week. A positional Megavoltage Computed Tomography was performed before each treatment session. All acute and late toxicities were graded according to Common Terminology Criteria for Adverse Events version 3.0. Survival analysis was performed using the Kaplan-Meier method. Median follow-up was 22.9 months. Fifty-four women and 10 men were treated (median age: 62 years). Nineteen patients (29.7 %) had T2, 16 patients (25.0 %) T3, and 27 patients (42.2 %) T4 tumours. Thirty-nine patients (60.9 %) had nodal involvement. Median tumour size was 45 mm (range, 10–110 mm). Seven patients had a colostomy before treatment initiation. Fifty-seven patients received concomitant chemotherapy (5-FU/cisplatin or 5-FU/mitomycin-based therapy). Forty-seven patients (73.4 %) experienced a complete response, 13 a partial response or local recurrence, and 11 had salvage surgery; among these, six became complete responders, three experienced metastatic failure, and two local failure. At least four patients experienced metastatic recurrence (concomitant to a local failure for one patient). The two-year overall survival was 85.6 % (95 %CI [71.1 %–93.0 %]), and the one-year disease-free survival, and colostomy-free survival were 68.7 % (95 %CI [54.4 %–79.4]), and 75.5 % (95 %CI [60.7 %–85.3 %]) respectively. Overall survival, disease-free survival and colostomy free-survival were significantly better for women than men (p = 0.002, p = 0.004, and p = 0.002 respectively). Acute grade ≥3 toxicity included dermatologic (46.9 % of patients), gastrointestinal (20

    Cross-sectional. To evaluate the accuracy with which physical therapists identify fear-avoidance beliefs in patients with low back pain by comparing therapist ratings of perceived patient fear-avoidance to the Fear-Avoidance Beliefs Questionnaire (FABQ), Tampa Scale of Kinesiophobia 11-item (TSK-11), and Pain Catastrophizing Scale (PCS). To compare the concurrent validity of therapist ratings of perceived patient fear-avoidance and a 2-item questionnaire on fear of physical activity and harm, with clinical measures of fear-avoidance (FABQ, TSK-11, PCS), pain intensity as assessed with a numeric pain rating scale (NPRS), and disability as assessed with the Oswestry Disability Questionnaire (ODQ). The need to consider psychosocial factors for identifying patients at risk for disability and chronic low back pain has been well documented. Yet the ability of physical therapists to identify fear-avoidance beliefs using direct observation has not been studied. Eight physical therapists and 80 patients with low back pain from 3 physical therapy clinics participated in the study. Patients completed the FABQ, TSK-11, PCS, ODQ, NPRS, and a dichotomous 2-item fear-avoidance screening questionnaire. Following the initial evaluation, physical therapists rated perceived patient fear-avoidance on a 0-to-10 scale and recorded 2 influences on their ratings. Spearman correlation and independent t tests determined the level of association of therapist 0-to-10 ratings and 2-item screening with fear-avoidance and clinical measures. Therapist ratings of perceived patient fear-avoidance had fair to moderate interrater reliability (ICC2,1 = 0.663). Therapist ratings did not strongly correlate with FABQ or TSK-11 scores. Instead, they unexpectedly had stronger associations with ODQ and PCS scores. Both 2-item screening questions were associated with FABQ-physical activity scores, while the fear of physical activity question was also associated with FABQ-work, TSK-11, PCS, and ODQ scores

    Management of deep facial burns remains one of the greatest challenges in burn care. We have developed a protocol over the past 20 years for management of facial burns that includes excision and coverage with thick autograft. However, the results were not perfect. Deformities of the eyelids, nose and mouth as well as the prominence of skin graft junctures demonstrated the need to explore novel approaches. Integra has been used with success in the management of burns of the trunk and extremities. The purpose of this study was to prospectively evaluate the aesthetic outcome of the use of Integra for deep facial burns. Twelve consecutive patients underwent excision of large, deep facial burns and placement of Integra. Integra provides excellent color and minimally visible skin graft junctures. The texture is good but not as supple as thick autograft. Integra is not well suited for use in the coverage of eyelid burns due to the need to wait 2 weeks for adequate vascularization. In summary, thick autograft remains the gold standard for deep facial burns. However, for patients with extensive burns and limited donor sites, Integra provides an acceptable alternative.

Tumors were classified by the 256 gene expression signature (CIT) and associated with basic clinical characteristics...... and aggregated expression levels in the hallmark gene sets. Results: Of the 1560 samples, 168 were classified basal-like and 120 patients were screened for BRCA1/2 mutations, resulting in 19 BRCA1/2 carriers, 95 non-carriers and six patients carried variants of unknown significance. The BRCA1/2 carriers were...... significantly younger and there were no carriers above 60 years of age. The tumors showed a loss in DNA-repair profile, as well as an upregulation in proliferative cancer signaling pathways. A robust molecular signature for identification of the BRCA1/2 - carriers was infeasible in the current cohort. Patients...

    Full Text Available Klinefelter syndrome (KS is a hypergonadotropic hypogonadism characterized by a 47, XXY karyotype. The risk of testicular cancer in KS is of interest in relation to theories about testicular cancer etiology generally; nevertheless it seems to be low. We evaluated the need for imaging and serum tumor markers for testicular cancer screening in KS. Participants were 40 consecutive KS patients, enrolled from December 2009 to January 2013. Lactate dehydrogenase (LDH, alpha-fetoprotein (AFP, and beta-human chorionic gonadotrophin subunit (β-HCG serum levels assays and testicular ultrasound (US with color Doppler, were carried out at study entry, after 6 months and every year for 3 years. Abdominal magnetic resonance (MR was performed in KS when testicular US showed micro-calcifications, testicular nodules and cysts. Nearly 62% of the KS had regular testicular echotexture, 37.5% showed an irregular echotexture and 17.5% had micro-calcifications and cysts. Eighty seven percent of KS had a regular vascular pattern, 12.5% varicocele, 12.5% nodules 1 cm. MR ruled out the diagnosis of cancer in all KS with testicular micro calcifications, nodules and cysts. No significant variations in LDH, AFP, and β-HCG levels and in US pattern have been detected during follow-up. We compared serum tumor markers and US pattern between KS with and without cryptorchidism and no statistical differences were found. We did not find testicular cancer in KS, and testicular US, tumor markers and MR were, in selected cases, useful tools for correctly discriminating benign from malignant lesions.

    In children with ileocolic intussusception sonography is increasingly being used for diagnosis, whereas fluoroscopy is frequently used for guiding non-invasive reduction. This study assessed the success rate of radiation-free sonography-guided hydrostatic reduction in children with ileocolic intussusception, using novel well-defined success rate indices. All children were evaluated who presented from 2005 to 2013 to the local university hospital with ileocolic intussusception. The patients were treated with sonography-guided hydrostatic reduction unless primary surgery was clinically indicated. The according success rate was determined by indices of Bekdash et al. They represent the ratio of persistently successful non-surgical reductions versus four different denominators, depending on including/excluding cases with primary surgery and including/excluding cases requiring bowel resection/intervention. Fifty-six consecutive patients were included (age, 3 months to 7.8 years). About 80% of the patients presented until 24 h and 20% until 48 h after the onset of symptoms. Seven patients underwent primary surgery, with bowel resection required in three cases. Hydrostatic reduction was attempted in 49 patients, being permanently successful in 41 cases (selective reduction rate 41/49 = 83.7%; crude reduction rate 41/56 = 73.2%). The remaining eight patients underwent secondary surgery, with just two patients not requiring surgical bowel resection/intervention (corrected selective reduction rate 41/43 = 95.3%). The composite reduction rate was 87.2% (successful/feasible reductions, 41/47). Radiation-free sonography-guided hydrostatic reduction has a good success rate in children with ileocolic intussusception. It may be particularly valuable in centers that are already experienced with using sonography for the diagnosis.

    Complete resection of the pyriform sinus fistula (PSF) tract is challenging due to repeated infection and inadequate procedures. We present our experiences with intraoperative endoscopic-assisted intubation or instillation of dye through the internal opening as a guide to identify the tract. We retrospectively reviewed the charts of 73 consecutive patients diagnosed with PSF during 1999 until 2014 from two tertiary referral centers. Demographics, clinical presentation, imaging, treatment, and outcome were analyzed. The intraoperative endoscopy was successfully conducted in all 73 cases. No gender predominance was observed. Of the anomalies, 94.5% were left-sided. Presenting symptoms consisted of neck abscess (n = 48), acute suppurative thyroiditis/thyroid abscess (n = 9), neck mass with or without dyspnea (n = 12), and thyroid nodule (n = 4). Barium esophagography and computed tomography scan with oral or intravenous contrast had a satisfactory positive predictive value. Partial thyroidectomy was performed on 25 cases (34.2%) if the ipsilateral thyroid was involved. Good outcome was achieved in all but 3 patients (70/73, 95.9%) during a median follow-up of 4 years (range, 8 months-14 years). Two patients developed postoperative complications: temporary vocal fold motion impairment and left-sided Horner's syndrome, respectively. PSF recurred in 1 case. A complete resection is essential for good outcomes. Intraoperative intubation or methylene blue injection by endoscopy can simplify the identification of the fistula tract during surgical exploration.

    Insole pressure sensors capture the force distribution patterns during the stance phase while walking. By comparing patterns obtained from healthy individuals to patients suffering different medical conditions based on a given similarity measure, automatic impairment indexes can be computed in order to help in applications such as rehabilitation. This paper uses the data sensed from insole pressure sensors for a group of healthy controls to train an auto-encoder using patterns of stochastic distances in series of consecutive steps while walking at normal speeds. Two experiment groups are compared to the healthy control group: a group of patients suffering knee pain and a group of post-stroke survivors. The Mahalanobis distance is computed for every single step by each participant compared to the entire dataset sensed from healthy controls. The computed distances for consecutive steps are fed into the previously trained autoencoder and the average error is used to assess how close the walking segment is to the autogenerated model from healthy controls. The results show that automatic distortion indexes can be used to assess each participant as compared to normal patterns computed from healthy controls. The stochastic distances observed for the group of stroke survivors are bigger than those for the people with knee pain.

    Pediatric convulsive status epilepticus with fever is common in the emergency setting but leads to severe neurological sequelae in some patients. To explore the epidemiology of convulsive status epilepticus with fever, a retrospective cohort covering all convulsive status epilepticus cases with fever seen in the emergency department of a tertiary care children's hospital were consecutively collected. Of the 381 consecutive cases gathered, 81.6% were due to prolonged febrile seizure, 6.6% to encephalopathy/encephalitis, 0.8% to meningitis, and 7.6% to epilepsy. In addition, seizures were significantly longer in encephalopathy/encephalitis cases than in prolonged febrile seizure cases (log rank test, P status epilepticus with fever in the emergency setting, and will help optimize the management of pediatric patients presenting to the emergency department with convulsive status epilepticus with fever. © The Author(s) 2016.

This research evaluated 520 consecutive dental extraction surgeries in which 680 teeth were removed. Data collection was obtained through a questionnaire of patients and of the undergraduate students who performed all procedures. Pain was evaluated through qualitative self-reported scores at seven days postsurgery. An increased pain level was statistically associated with ostectomy, postoperative complications, and tobacco consumption. Pain that persisted for more than two days was statistically associated with the amount of anesthetic solution used, with a notable increase in surgical time and development of postoperative complications. Periods of pain lasting more than two days could be expected for traumatic surgeries lasting more than 30 minutes. Both severe and prolonged pain were signs of development of postoperative complications, such as alveolar osteitis and alveolar infection.

    Endoscopy is performed with air insufflation and is usually associated with abdominal pain. It is well recognized that carbon dioxide (CO 2 ) is absorbed more quickly into the body than air; however, to date, few studies have investigated the use of CO 2 insufflation during consecutive EGD and colonoscopy (CEC). Thus, this study evaluated the efficacy of CO 2 insufflation compared with air insufflation in CEC. From March 2014 to April 2016, a total of 215 consecutive patients were randomly assigned to receive CO 2 insufflation (CO 2 group, n = 108) or air insufflation (air group, n = 107). Abdominal pain after CEC was recorded on a visual analogue scale (VAS). The amount of sedatives administered, use of analgesics, polyp detection rate (PDR), adenoma detection rate (ADR), abdominal circumference, and adverse events were also analyzed. Baseline patient characteristics were not significantly different between the groups. Abdominal pain on the VAS in the CO 2 group and air group 1 hour after CEC was, respectively, 13.8 and 20.1 (P = .010), 3 hours after CEC was 8.3 and 12.5 (P = .056), 6 hours after CEC was 3.5 and 5.3 (P = .246), and 1 day after CEC was 1.8 and 3.4 (P = .192). The dose of sedative administered, analgesic usage, PDR, ADR, and adverse events were not statistically different between the groups. However, the increase in abdominal circumference was significantly higher in the air group than in the CO 2 group. CO 2 insufflation was superior to air insufflation with regard to the pain score on the VAS in the hour after CEC. (Clinical trial registration number: KCT0001491.).

    Predicting relapse in inflammatory bowel disease (IBD) patients could allow early changes in therapy. We aimed at evaluating the accuracy of consecutive fecal calprotectin (FC) measurements to predict flares in IBD patients under maintenance treatment with anti-tumor necrosis factor (TNF) drugs. A prospective longitudinal cohort study with 16-month follow-up period was designed. IBD patients in clinical remission for at least 6 months under anti-TNF therapy were included. FC was quantified at 4-month intervals for 1 year, and patients were clinically evaluated for relapse at 2-month intervals. Diagnostic accuracy of FC for predicting relapse was evaluated by receiver-operating characteristic curve analysis. In total, 95 of 106 included patients finalized the study and were analyzed (median age 44 y, 50.5% female, 75% with Crohn's disease). A total of 30 patients (31.6%) had a relapse over follow-up. FC concentration was significantly higher in patients who relapsed (477 μg/g) than in patients who maintained in remission (65 μg/g) (Ppredict remission was 130 μg/g (negative predictive value of 100%), and 300 μg/g to predict relapse (positive predictive value of 78.3%). FC is a good predictor of clinical relapse and a particularly good predictor of remission over the following 4 months in patients with IBD on maintenance therapy with anti-TNF drugs. FC levels 300 μg/g allow predicting relapse with a high probability at any time over the following 4 months.

    Aim: To assess the feasibility and safety of fluoroscopically guided percutaneous jejunostomy. Material and methods: Between May 1999 and August 2006 percutaneous jejunostomy was attempted in 25 patients. A 5 F vascular catheter (n = 20) or a 7.5 F multifunctional coil catheter (n = 5) was used to insufflate the jejunum. The distended jejunum was punctured using a 17 G needle (n = 19) or a 21 G Chiba needle (n = 6) with the inserted catheter as a target. A 12 or 14 F loop feeding tube was inserted after serial dilations. The technical success, complications, 30-day mortality, and in-dwelling period of the feeding tube placement were evaluated. Results: The technical success rate was 92% (23/25). Technical failures (n = 2) resulted from the inability to insufflate the jejunum secondary to failure to pass the catheter through a malignant stricture at the oesophagojejunostomy site and thus subsequent puncture of the undistended jejunum failed, or failure to introduce the Neff catheter into the jejunum. Pericatheter leakage with pneumoperitoneum was a complication in three patients (12%) and was treated conservatively. The 30-day mortality was 13% (3/23); however, there was no evidence that these deaths were attributed to the procedure. Except for four patients who were lost to follow-up and two failed cases, 15 of the 19 jejunostomy catheters were removed because of patient death (n = 12) or completion of treatment (n = 3), with a mean and median in-dwelling period of 231 and 87 days, respectively. Conclusions: Fluoroscopically guided percutaneous jejunostomy is a feasible procedure with a high technical success and a low complication rate. In addition to a 17 G needle, a 21 G needle can safely be used to puncture the jejunum

    Between 26% and 42% of chronic low back pain is attributed to internal disc disruption of lumbar intervertebral discs. These prevalence estimates and data characterizing discogenic pain originate largely from research at elite practices, conducted 20 years ago. With few studies since, their concordance with rates in community practice has rarely been addressed. To assess the prevalence and key features of discogenic pain within community-based tertiary practice, and to evaluate the accuracy and clinical utility of discography. This prospective, three-year study of 223 consecutive cases of chronic low back pain used image-guided lumbar discography to identify symptomatic and flanking asymptomatic discs. A subset of patients (n = 195) had previously undergone posterior column blocks to investigate spinal facet and/or sacroiliac joints as contributing pain sources. A total of 644 discs were tested without infection or complication. Positive discograms were recorded in 74% of patients, with 22.9% negative and 3.1% assessed as indeterminate. Among patients receiving both discography and diagnostic blocks, 63% had proven discogenic pain, 18% had pain of mixed etiology and 14% remained undiagnosed. Taking into account all low back pain cases during this study (n = 756), discogenic pain prevalence was 21.8% (95% CI: 17-26%). The prevalence of discogenic pain in this community practice is below the range, but within confidence intervals, previously reported. Prevalence is considerably elevated, however, among well-selected patients and discography enabled a firm diagnosis in most such cases. These findings are broadly in keeping with those reached in key publications and support the clinical utility of discography. Wiley Periodicals, Inc.

    Increasingly the trans-radial route (TRR) is preferred over the trans-femoral route (TFR) for PCI. However, even in high volume default TRR centers a cohort of patients undergo TFR PCI. We examined the demographics, procedural characteristics, and outcomes of patients undergoing PCI via the TF. The patient demographics, procedural data, and outcomes of 5,379 consecutive patients undergoing PCI at a default radial center between 2009 and 2012 were examined. Major bleeding (MB) was classified by ACUITY and BARC definitions. A total of 559 (10.4%) patients underwent PCI via the TFR and 4,820 patients via the TRR (89.6%). Baseline variables associated with TFR were shock, previous CABG, chronic total occlusion intervention, rotablation/laser use, female sex, and renal failure. Sixty-five patients of the TFR cohort (11.6%) experienced MB with 27 (41.5%) being access site related. MB was significantly more frequent than in the radial cohort. The variables independently associated with MB in the TFR cohort were renal failure, acute presentation, shock, and age. In the TFR, patients with MB mortality was high at 30 days (17.2% vs 2.6% for no MB, P default radial PCI center 10% of patients undergo PCI via the femoral artery. These patients have high baseline bleeding risk and undergo complex interventions. As a result the incidence of major bleeding, transfusion and death are high.

    Full Text Available Abstract Background Post-traumatic ventilator-associated pneumonia (VAP is a substantial clinical problem that increases hospital costs and typically adds to the duration of mechanical ventilation. We evaluated the impact of VAP on ventilator days. We also assessed 48-hour total blood cholesterol (TC and other potential risk factors for the development of VAP. Methods We performed a retrospective study of consecutive trauma patients requiring emergency tracheal intubation and evaluated TC, age, gender, ethanol status, smoker status, injury mechanism, chest injury, brain injury, Injury Severity Score (ISS, shock, day-one hypoxemia, and RBC transfusion as potential risks for VAP. Results The 152 patients had ISS 28.1, brain injury 68.4%, VAP 50.0%, ventilator days 14.3, and death 9.9%. Ventilator days were increased with late VAP (p Conclusions Severe traumatic injury produced substantial hypocholesterolemia that is greater with chest injury, shock, and RBC transfusion, but less with brain injury. Total blood cholesterol tended to decrease with increasing injury severity. However, attenuated hypocholesterolemia (ISS ≥ 20-&-TC ≥ 90 mg/dL represents a unique response that can occur with critical injury. Attenuated hypocholesterolemia signals early risk for late VAP, ventilator dependency, and death.

    Purpose: Choroidal melanomas usually present a characteristic appearance in MRI. Differing characteristics can cause problems in differential diagnosis between melanomas and other masses in the globe. The purpose of this study was to evaluate the appearance of choroidal melanomas with MRI in a large consecutive patient group. Methods: In a prospective study, 200 patients with choroidal melanomas were investigated with MRI using a 1.5 T scanner and a 5 cm surface coil. Both quantitative and qualitative evaluation of the resulting images was performed. Results: 78.5% of the melanomas presented with homogeneous signal intensities within the tumor due to a homogeneous pigmentation whereas 21.5% of the melanomas demonstrated a mixed pigmentation. Signal intensities of the homogeneous melanomas in the plain T 1 -WI were moderately or markedly hyperintense compared to the vitreous in 29.3% and moderately or markedly hypointense in the T 2 -WI in 37.1%. An accompanying retinal detachment was found in 65.5% and an extraocular growth in 7.0%. Conclusions: In 10% to 37% we observed the typical well known MR appearance, including homogenous high signal in the T 1 -WI and low signals in the T 2 -WI. For further differentiation, morphological criteria (e.g. shape, size, and position) were used, which are also discussed. (orig.) [de

    Objective: To assess causes, incidence and patterns of perfusion defects (PDs) on dual-energy perfusion CT angiography (DECTA) in clinically suspected acute pulmonary thromboembolisms (PTE). Materials and methods: Consecutive 537 patients who underwent DECTA for suspicion of PTE were retrospectively reviewed. After excluding patients with possible PTE or unsatisfactory perfusion map quality, 299 patients with 1697 lobes were included. The DECTA (Somatom Definition, Siemens) was performed at 140 kV and 80 kV. Color-coded perfusion images were obtained with a lung PBV application of the workstation software (Syngo Dual Energy). The presence, incidence, three patterns of PDs (wedge-shaped, heterogeneous, and regionally homogeneous), pulmonary diseases, and the matchedness between the PD and the disease extent were studied. Results: 315 of 1697 lobes (18.6%) in 156 of 299 patients (81.3%) showed PDs. Among them, 51 (3%), 257 (15.1%), and 7 (0.4%) lobes had PDs due to vascular, nonvascular, and unidentifiable causes, respectively. Vascular causes include: pulmonary arterial (PA) hypertension (0.7%), extrinsic occlusion of PA by fibrosis (0.6%), PA hypoplasia (0.6%), vasculitis (0.5%), cancer mass compressing PA, venous occlusion, AVM, and pulmonary angiosarcoma. Most of PDs were wedge-shaped and well-matched. Nonvascular causes include: mosaic attenuation (4.1%), emphysema (3.2%), interstitial fibrosis (1.6%), bronchitis (1.4%), GGO (1.2%), cellular bronchiolitis (1%), bronchiectasis, airway obstruction, compensaroty lung hyperinflation, air trapping, cor-pulmonale, bronchopneumonia, physiologic decreased ventilation, and segmental bronchial atresia. Most of PDs showed heterogeneous pattern and were not matched. Conclusions: Various vascular and nonvascular diseases cause PDs on DECTA. Each disease shows different pattern of PD depending on pathophysiology and physiologic compensation.

    Full Text Available Abstract Objective To describe management and clinical features observed in a patient's seven spontaneous pneumothoraces that developed during two consecutive pregnancies involving both hemithoraces. Materials and methods A 21 year old former smoker developed three spontaneous left pneumothoraces in the index pregnancy, having already experienced four right pneumothorax events in a prior pregnancy at age 19. Results Chest tubes were required in several (but not all hospitalizations during these two pregnancies. Following her fourth right pneumothorax, thoracoscopic excision of right apical lung blebs and mechanical pleurodesis was performed. The series of left pneumothoraces culminated in mini-thoracotomy and thoracoscopically directed mechanical pleurodesis. For both pregnancies unassisted vaginal delivery was performed with no adverse perinatal sequelae. With the exception of multiple pneumothoraces, there were no additional pregnancy complications. Conclusion Spontaneous pneumothorax in pregnancy is believed to be a rare phenomenon, yet the exact incidence is unknown. Here we present the first known case of multiple spontaneous pneumothoraces in two consecutive pregnancies involving both hemithoraces. Clinical management coordinated with obstetrics and surgical teams facilitated a satisfactory outcome for both pregnancies. The diagnosis of pneumothorax should be contemplated in any pregnant patient with dyspnea and chest pain, followed by radiographic confirmation.

    Coronary artery anomalies are not common, but could be very serious. This study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (MDCT). The results of cardiac MDCT study in 2697 consecutive patients were analyzed retrospectively. Acquisition was performed by a 64-detector row CT machine. Imaging results were assessed by experienced radiologists. Myocardial bridging was by far the most frequent coronary variant (n = 576, 21.3%). Eighty-three subjects (3.1%) showed other coronary anomalies and variants. Anomalies of origination and course of the left main coronary artery (LMCA) were detected in 1.09% of the subjects. The frequency of these anomalies in the right coronary artery (RCA), left circumflex artery (LCx), left anterior descending artery (LAD), posterior descending artery (PDA) and obtuse marginal (OM) artery were 1.24%, 0.33%, 0.1%, 0.07% and 0.03%, respectively. The single coronary pattern was seen in 0.18% and coronary fistulas in 0.07%. Based on the fact that coronary CT-angiography using MDCT can display different coronary anomalies, this study shows similar results to other reports on the subject. Future advances in the performance of CT machines will further improve the quality of CT-based cardiac imaging

    About one half of adults with acute lymphoblastic leukemia are not cured of the disease and ultimately die. The objective of this study was to explore the factors influencing the outcome of adult patients with relapsed acute lymphoblastic leukemia. We analyzed the characteristics, the outcome and the prognostic factors for survival after first relapse in a series of 263 adult patients with acute lymphoblastic leukemia (excluding those with mature B-cell acute lymphoblastic leukemia) prospectively enrolled in four consecutive risk-adapted PETHEMA trials. The median overall survival after relapse was 4.5 months (95% CI, 4-5 months) with a 5-year overall survival of 10% (95% CI, 8%-12%); 45% of patients receiving intensive second-line treatment achieved a second complete remission and 22% (95% CI, 14%-30%) of them remained disease free at 5 years. Factors predicting a good outcome after rescue therapy were age less than 30 years (2-year overall survival of 21% versus 10% for those over 30 years old; P<0.022) and a first remission lasting more than 2 years (2-year overall survival of 36% versus 17% among those with a shorter first remission; P<0.001). Patients under 30 years old whose first complete remission lasted longer than 2 years had a 5-year overall survival of 38% (95% CI, 23%-53%) and a 5-year disease-free survival of 53% (95% CI, 34%-72%). The prognosis of adult patients with acute lymphoblastic leukemia who relapse is poor. Those aged less than 30 years with a first complete remission lasting longer than 2 years have reasonable possibilities of becoming long-term survivors while patients over this age or those who relapse early cannot be successfully rescued using the therapies currently available.

    We report the results of three consecutive programs combining initial intensive chemotherapy and radiotherapy in the treatment of patients with limited small-cell lung cancer (SCLC). The objective was to test the feasibility and the effect of high-dose chemotherapy and three thoracic irradiation programs on survival and patterns of relapse. Forty-two patients with limited SCLC were enrolled. All patients received high-dose chemotherapy (vindesine, etoposide, doxorubicin, cisplatin and cyclophosphamide or ifosfamide). In the SC 84 program, chest and brain radiotherapy was delivered during each course of chemotherapy, with a complementary irradiation after chemotherapy. In the SC 86 and SC 92 programs, patients received chemotherapy followed by thoracic irradiation and prophylactic brain and spinal axis radiotherapy. At the end of treatment, 40 patients (95%) were in complete response. During chemotherapy, high levels of toxicity were noted. All patients had grade IV hematological toxicities. The extra-hematological toxicities were digestive (grade III: 21%; grade IV: 7%) and hepatic (grades III and IV: 14%). During irradiation, patients presented digestive, pulmonary and hematological toxicities. Five patients developed late toxicities and a second malignancy was observed in 4 patients. The 2- and 5-year survival rates for all patients were 51% and 27%, respectively. Despite the marked toxicity of the initial intensive chemotherapy, the treatments are tolerable and effective in the control of extra-thoracic micrometastases, whereas they are less effective for thoracic primary tumor

    Working memory is the system that actively holds multiple pieces of transitory information in the mind, where they can be manipulated. In interpreting, working memory is in charge of the storage and processing of immediate information, thus making an important factor in influencing interpreting quality. The role played by working memory capacity in interpreting re-mains to be a hotspot issue in the field of interpreting research.This thesis aims to investigate the relationship between working memory capacity and E-C consecutive interpreting by conducting two tests. The first test is working memory span test and the second one is E-C consecutive interpreting test. By comparing and analyzing the results of two tests, this thesis comes to the con-clusion that working memory capacity is positively correlated with E-C consecutive interpreting in terms of fluency and logic.

    Pseudostellaria heterophylla is an important medicinal plant in China. However, cultivation of P. heterophylla using consecutive monoculture results in significant reductions in yield and quality. In this study, terminal-restriction fragment length polymorphism (T-RFLP) analysis and measurement of soil enzyme activities were used to investigate the regulation of soil micro-ecology to identify ways to overcome the negative effects of P. heterophylla consecutive monoculture. T-RFLP analysis showed that rice/P. heterophylla (RP) and bean/P. heterophylla (BP) crop rotation systems increased the number and diversity of microbial groups in P. heterophylla rhizosphere soil. In particular, the RP and BP crop rotations increased the number and abundance of beneficial bacterial species compared with two-year consecutive monoculture of P. heterophylla. The presence of these beneficial bacteria was positively correlated with soil enzyme activities which increased in rhizosphere soils of the RP and BP crop rotation systems. The results indicated that crop rotation systems could increase activities of key soil enzymes and beneficial microbial groups and improve soil health. This study could provide a theoretical basis to resolve the problems associated with P. heterophylla consecutive monoculture. (author)

    With use of a nonpharmacological, simple, and inexpensive program for blood conservation, 500 consecutive patients underwent elective coronary artery bypass grafting without need of homologous red cell transfusions in 493 (98.6%). At least one internal mammary artery was grafted in all but 1 patient, with supplemental saphenous vein grafts. Intraoperatively, autologous heparinized blood was removed before bypass and retransfused at the conclusion of extracorporeal circulation. The volume remaining in the oxygenator and tubing set was returned without cell processing or hemofiltration. Using the hard-shell cardiotomy reservoir from the heart-lung machine, autotransfusion of the shed mediastinal blood was continued hourly up to 18 hours after operation. The mean postoperative mediastinal blood loss was 643 +/- 354 mL, whereas 624 +/- 296 mL was autotransfused. Thirteen patients (2.6%) needed reexploration for bleeding, of whom 7 (7/500, 1.4%) received homologous blood. No other patients required red cell transfusions. In addition, 9 patients were given a mean of 2.6 units of fresh frozen plasma because of suspected coagulopathy. No platelets were transfused, and no cryoprecipitate therapy was undertaken. Thus, in total, 484 patients (96.8%) were not exposed to any homologous blood products during the hospital stay. At discharge, the mean hemoglobin concentration was 121 +/- 14 g/L (12.1 +/- 1.4 g/dL) and the hematocrit, 0.36 +/- 0.04. Postoperative complications were few. There was one in-hospital death (0.2%).

    Full Text Available Introduction. Repair of hiatal hernias has been performed traditionally via open laparotomy or thoracotomy. Since first laparoscopic hiatal hernia repair in 1992, this method had a growing popularity and today it is the standard approach in experienced centers specialized for minimally invasive surgery. Objective. In the current study we present our experience after 200 consecutive laparoscopic hiatal hernia repairs. Methods. A retrospective cohort study included 200 patients who underwent elective laparoscopic hiatal hernia repair at the Department for Minimally Invasive Upper Digestive Surgery, Clinic for Digestive Surgery, Clinical Center of Serbia in Belgrade from April 2004 to December 2013. Results. Hiatal hernia types included 108 (54% patients with type I, 30 (15% with type III, 62 (31% with giant paraesophageal hernia, while 27 (13.5% patients presented with a chronic gastric volvulus. There were a total of 154 (77% Nissen fundoplications. In 26 (13% cases Nissen procedure was combined with esophageal lengthening procedure (Collis-Nissen, and in 17 (8.5% Toupet fundoplications was performed. Primary retroesophageal crural repair was performed in 164 (82% cases, Cleveland Clinic Foundation suture modification in 27 (13.5%, 4 (2% patients underwent synthetic mesh hiatoplasty, 1 (0.5% primary repair reinforced with pledgets, and 4 (2% autologous fascia lata graft reinforcement. Poor result with anatomic and symptomatic recurrence (indication for revisional surgery was detected in 5 patients (2.7%. Conclusion. Based on the result analysis, we found that laparoscopic hiatal hernia repair was a technically challenging but feasible technique, associated with good to excellent postoperative outcomes comparable to the best open surgery series.

    Oral anticoagulant therapy for more than 6 months in patients with an episode of idiopathic thromboembolic disease is controversial. The objective was to determine predictive clinical signs that identify patients at increased risk of thromboembolic recurrence after stopping anticoagulant therapy for 6 months after an episode of idiopathic deep vein thrombosis (DVT). A prospective study which included 306 consecutive patients with a first episode of idiopathic DVT from June 2012 to June 2014. Predictor variables of recurrent thromboembolic disease and episodes of recurrence during follow-up of the patients (28.42 months) were collected. We performed a multivariate analysis to analyze possible predictors (Pthrombus (P=.001) in males, and persistence of residual thrombus in women (P=.046). The mean recurrence-free survival was shorter in both groups. The presence of echogenic thrombus in men and the existence of residual DVT in women were 2 clinical signs associated with increased risk of thromboembolic recurrence after stopping anticoagulant therapy for 6 months after an episode of idiopathic DVT in our study.

    Accumulated experience and improvement of stents dedicated to intracranial use have significantly widened the applicability of stent-assisted coiling (SAC) to ruptured wide-necked aneurysms. This retrospective study was designed to evaluate the safety and efficacy of SAC using the Enterprise stent for ruptured wide-necked intracranial aneurysms during ultra-early subarachnoid hemorrhage. We reviewed data from 59 consecutive patients with ruptured wide-necked aneurysms who had SAC using the Enterprise stent performed within 48hours of onset. Data collected and analyzed included: patient demographics; morphologic features of the aneurysm; treatment results and follow-up results. Clinical outcomes were evaluated by modified Rankin Scale (mRS). In all 59 cases, SAC using the Enterprise stent was performed successfully, with no significant technical difficulties. Initial angiographic results were: complete occlusion in 38 cases; near occlusion in 17; and partial occlusion in four. Angiographic follow-up of 48 patients showed that 46 (95.8%) remained stable or improved, without regrowth, while regrowth was imaged in two patients. Medium-term clinical follow-up of 54 patients (mean, 26.9months) showed that 88.9% had a good outcome (mRS: 0 in 34; 1 in eight; and 2 in six), and 11.1% poor outcomes (mRS: 3 in four; and 4 in two). Enterprise SAC is a safe and viable option for treatment of ruptured wide-necked aneurysms within 48hours of ictus. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Full Text Available Abstract Background Combined kidney pancreas transplantation (PTx evolved as excellent treatment for diabetic nephropathy. Infections remain common and serious complications. Methods 217 consecutive enteric drained PTxs performed from 1997 to 2004 were retrospectively analyzed with regard to bloodstream infection. Immunosuppression consisted of antithymocyteglobuline induction, tacrolimus, mycophenolic acid and steroids for the majority of cases. Standard perioperative antimicrobial prophylaxis consisted of pipercillin/tazobactam in combination with ciprofloxacin and fluconazole. Results One year patient, pancreas and kidney graft survival were 96.4%, 88.5% and 94.8%, surgical complication rate was 35%, rejection rate 30% and rate of infection 59%. In total 46 sepsis episodes were diagnosed in 35 patients (16% with a median onset on day 12 (range 1–45 post transplant. Sepsis source was intraabdominal infection (IAI (n = 21, a contaminated central venous line (n = 10, wound infection (n = 5, urinary tract infection (n = 2 and graft transmitted (n = 2.

Gram negative rods were cultured in twelve cases (18%. Patients with blood borne infection had a two year pancreas graft survival of 76.5% versus 89.4% for those without sepsis (p = 0.036, patient survival was not affected. Conclusion Sepsis remains a serious complication after PTx with significantly reduced pancreas graft, but not patient survival. The most common source is IAI.

    To evaluate the clinical performance of provisional screw-retained metal-free acrylic restorations in an immediate loading implant protocol. Two hundred and forty-two consecutive patients were selected retrospectively, who received 1011 implants and 311 immediate provisional screw-retained implant restorations (2-4 h after implant surgery). The patients were monitored for a period of 2-3 months, until they were referred for a final restoration. The primary variables recorded include the survival time and the appearance of fractures in the provisional restoration, and the independent variables included age, sex, dental arch, type of restoration, type of attachment and components used, as well as cantilevers and opposing dentition. A survival analysis (Kaplan-Meier) and a Cox regression analysis were performed. Twenty-three restorations in 20 patients (8.26%, 95% CI 4.8-11.7) showed at least one fracture (7.39%). More than half of the new fractures (52%, 12 cases) occurred in the first 4 weeks. The cumulative survival probability observed was greater in mandible (P=0.05) and non-cantilever restorations (P=0.001), and in those opposed by full restorations or natural teeth (P=0.001). With an opposing implant-supported prosthesis, the risk of fracture was multiplied by 4.7, and the use of cantilevers as well as the location of the restoration in the maxilla multiply the risk by 3.4-3.5. Immediate provisional screw-retained metal-free implant-supported restorations can be considered a reliable restoration (92.6% remain intact) for the healing period of 3 months. © 2010 John Wiley & Sons A/S.

    Malnutrition is common among patients with cancer, but little attention is given to its risks and consequences. The aim of this study is to assess the nutritional status and identify the factors associated with malnutrition among newly diagnosed patients with cancer. Patients admitted with newly diagnosed cancer at a teaching hospital in Malaysia were recruited from January to April 2015. Nutritional status was assessed before treatment initiation, and patients were classified into three categories. A total of 132 pretreatment patients were recruited into the study. About half were severely malnourished. Patients with stage III cancer had the highest prevalence of severe malnourishment. Clinical parameters and disease characteristics were significantly associated with nutritional status. Demographic variables were also statistically significantly associated with severe nutritional status.

    Patients with rotator cuff tears often recall a specific initiating event (traumatic), whereas many cannot (nontraumatic). It is unclear how important a history of trauma is to the outcomes of rotator cuff repair. This question was addressed in a study cohort of 1300 consecutive patients who completed a preoperative questionnaire regarding their shoulder injury and had a systematic evaluation of shoulder range of motion and strength, a primary arthroscopic rotator cuff repair performed by a single surgeon, an ultrasound scan, and the same subjective and objective measurements made of their shoulder 6 months after surgery. Post hoc, this cohort was separated into 2 groups: those who reported no history of trauma on presentation (n = 489) and those with a history of traumatic injury (n = 811). The retear rate in the group with no history of trauma was 12%, whereas that of the group with a history of trauma was 14% (P = .36). Those patients with a history of shoulder trauma who waited longer than 24 months had higher retear rates (20%) than those who had their surgery earlier (13%) (P = .040). Recollection of a traumatic initiating event had little effect on the outcome of arthroscopic rotator cuff repair. Duration of symptoms was important in predicting retears if patients recalled a specific initiating event but not in patients who did not recall any specific initiating event. Patients with a history of trauma should be encouraged to have their rotator cuff tear repaired within 2 years. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

    [Correction Notice: An Erratum for this article was reported in Vol 29(11) of Psychological Assessment (see record 2016-56886-001). In the article, several values were reversed and the mean was misreported in Table 2. The corrected table is present in the erratum.] Pathological narcissism represents a clinically relevant, albeit controversial personality construct, with multiple conceptualizations that are operationalized by different measures. Even in the recently published Diagnostic and Statistical Manual for Mental Disorders-Fifth Edition (DSM-5), 2 different views of narcissistic personality disorder (NPD) are formulated (i.e., Section II and Section III). The DSM-5 Section III alternative PD model diagnosis of NPD is based on self and interpersonal dysfunction (Criterion A) and a profile of maladaptive personality traits (Criterion B), specifically elevated scores on Attention Seeking and Grandiosity. Given the diversity of conceptualizations of pathological narcissism, we evaluated the convergences and divergences in DSM-5 trait profiles characterizing multiple measures of narcissism in a clinical sample of 278 consecutively admitted Italian psychotherapy patients. Patients were administered the Italian versions of the Personality Inventory for DSM-5 (PID-5) and 4 measures of NPD, (a) the Narcissistic Personality Inventory (NPI); (b) the NPD scale of the Personality Diagnostic Questionnaire-4+; (c) the Structured Clinical Interview for Axis II Personality Disorders, Version 2.0 (SCID-II) as an observer-rated measure of NPD; and (d) the Pathological Narcissism Inventory (PNI). Multiple regression analyses showed that PID-5 traits explained from 13% to more than 60% of the variance in the different NPD measures. Attention Seeking was consistently associated with all measures of NPD, whereas Grandiosity was associated with some of the NPD measures. All measures of NPD were also significantly related to additional DSM-5 maladaptive traits. (PsycINFO Database

    For more than 30 years, fragrance mix I (FMI) has been the most important screening marker for fragrance contact allergy. Meanwhile, governmental and corporate initiatives have been implemented, aimed at reducing sensitization to fragrance allergens, including the single constituents of FMI. To examine trends in contact allergy to FMI from 1986 to 2015 in patients with dermatitis, and to test the hypothesis that sensitization to the fragrance screening marker has decreased within recent years. This was a cross-sectional registry study on patch test results to FMI among consecutively tested patients with dermatitis from a single university clinic across three 10-year periods. From 2006 to 2015, data on eczema location according to the MOAHLFA index (male; occupation; atopic dermatitis; hand; leg; face; age ≥ 40 years), clinical relevance of sensitization, and cosmetic exposures were available. Of 24 168 patients, 7·8% (95% confidence interval 7·4-8·1) were sensitized to FMI. For women, a significant trend (P = 0·004) was observed for an increase in sensitization to FMI across the three decades. From 2011 to 2015, the prevalence of contact allergy to FMI increased significantly for women (8·0% vs. 10·4%, P = 0·002) and men (4·4% vs. 7·3%, P = 0·002) compared with the previous 5-year period. From 2006 to 2015, clinical relevance was established in 78·2% of FMI-positive patients with no differences over time. An increase (28·6% vs. 36·1%, P = 0·05) in FMI-positive patients suffering from facial dermatitis was observed for the period 2011 to 2015 compared with 2006 to 2010. The prevalence of contact allergy to FMI has been increasing in recent years. There was no demonstrable effect of previous preventive initiatives. © 2016 British Association of Dermatologists.

  5. Using Active Learning to Identify Health Information Technology Related Patient Safety Events.

    The widespread adoption of health information technology (HIT) has led to new patient safety hazards that are often difficult to identify. Patient safety event reports, which are self-reported descriptions of safety hazards, provide one view of potential HIT-related safety events. However, identifying HIT-related reports can be challenging as they are often categorized under other more predominate clinical categories. This challenge of identifying HIT-related reports is exacerbated by the increasing number and complexity of reports which pose challenges to human annotators that must manually review reports. In this paper, we apply active learning techniques to support classification of patient safety event reports as HIT-related. We evaluated different strategies and demonstrated a 30% increase in average precision of a confirmatory sampling strategy over a baseline no active learning approach after 10 learning iterations.

    2017-09-01

    To evaluate the sensitivity and specificity of quantitative EEG (QEEG) spectrograms in order to distinguish epileptic from non-epileptic events. Seventeen patients with paroxysmal non-epileptic events, captured during EEG monitoring, were retrospectively assessed using QEEG spectrograms. These patients were compared to a control group of 13 consecutive patients (ages 25-60 years) with epileptic seizures of similar semiology. Assessment of raw EEG was employed as the gold standard against which epileptic and non-epileptic events were validated. QEEG spectrograms, available using Persyst 12 EEG system integration software, were each assessed with respect to their usefulness to distinguish epileptic from non-epileptic seizures. The given spectrogram was interpreted as indicating a seizure if, at the time of the clinically identified event, it showed a visually significant change from baseline. Eighty-two clinically identified paroxysmal events were analysed (46 non-epileptic and 36 epileptic). The "seizure detector trend analysis" spectrogram correctly classified 33/46 (71%) non-epileptic events (no seizure indicated during a clinically identified event) vs. 29/36 (81%) epileptic seizures (seizure indicated during a clinically identified event) (p=0.013). Similarly, "rhythmicity spectrogram", FFT spectrogram, "asymmetry relative spectrogram", and integrated-amplitude EEG spectrogram detected 28/46 (61%), 30/46 (65%), 22/46 (48%) and 27/46 (59%) non-epileptic events vs. 27/36 (75%), 25/36 (69%), 25/36 (69%) and 27/36 (75%) epileptic events, respectively. High sensitivities and specificities for QEEG seizure detection analyses suggest that QEEG may have a role at the bedside to facilitate early differentiation between epileptic seizures and non-epileptic events in order to avoid unnecessary administration of antiepileptic drugs and possible iatrogenic consequences.

    Bone single photon emission computed tomography (SPECT)/CT is considered as beneficial in unhappy patients with pain, stiffness or swelling after total knee arthroplasty (TKA). The purpose of this study was to identify typical patterns of bone tracer uptake (BTU), distribution and intensity values in patients after TKA. The above findings were correlated with the type and fixation of TKA, the time from TKA and intraoperative findings at revision surgery. A total of 100 knees of 84 consecutive patients (mean age ± SD 70 ± 11 years) after TKA with persistent knee pain were prospectively included. All patients underwent clinical examination, standardized radiographs and {sup 99m}Tc-hydroxymethane diphosphonate (HDP) SPECT/CT as part of a routine diagnostic algorithm. The diagnosis before and after SPECT/CT and final treatment were recorded. TKA component position was determined on 3-D reconstructed images. Intensity and anatomical distribution of BTU was determined. Maximum intensity values were recorded as well as ratios in relation to the proximal midshaft of the femur. Univariate analyses (chi-square test, Pearson's correlation and t test for independent samples) were performed (p < 0.05). SPECT/CT changed the clinical diagnosis and final treatment in 85/100 (85 %) knees. Intraoperative findings confirmed the preoperative SPECT/CT diagnosis in 32/33 knees (97 %). TKA loosening as well as progression of patellofemoral osteoarthritis (OA) was correctly diagnosed in 100 % of knees. Typical patterns of BTU for specific pathologies were identified. Loose femoral TKA components significantly correlated with increased BTU at the lateral femoral regions (p < 0.05). Loose tibial TKA components significantly correlated with increased BTU at all tibial regions (p < 0.05) and around the tibial peg (p > 0.01). The diagnostic benefits of SPECT/CT in patients after TKA have been proven. Typical pathology-related BTU patterns were identified, which will improve reporting

    Asthma is a highly heterogeneous disease that can be classified into different clinical phenotypes, and treatment may be tailored accordingly. However, factors beyond purely clinical traits, such as patient attitudes and behaviors, can also have a marked impact on treatment outcomes. The objective of this study was to further analyze data from the REcognise Asthma and LInk to Symptoms and Experience (REALISE) Europe survey, to identify distinct patient groups sharing common attitudes toward asthma and its management. Factor analysis of respondent data (N = 7,930) from the REALISE Europe survey consolidated the 34 attitudinal variables provided by the study population into a set of 8 summary factors. Cluster analyses were used to identify patient clusters that showed similar attitudes and behaviors toward each of the 8 summary factors. Five distinct patient clusters were identified and named according to the key characteristics comprising that cluster: "Confident and self-managing," "Confident and accepting of their asthma," "Confident but dependent on others," "Concerned but confident in their health care professional (HCP)," and "Not confident in themselves or their HCP." Clusters showed clear variability in attributes such as degree of confidence in managing their asthma, use of reliever and preventer medication, and level of asthma control. The 5 patient clusters identified in this analysis displayed distinctly different personal attitudes that would require different approaches in the consultation room certainly for asthma but probably also for other chronic diseases.

  10. Identifying elements of patient-centered care in underserved populations: a qualitative study of patient perspectives.

    Directory of Open Access Journals (Sweden)

    Sheela Raja

    Full Text Available Patient-centered care is an important goal in the delivery of healthcare. However, many patients do not engage in preventive medical care. In this pilot study, we conducted twenty in depth, semi-structured qualitative interviews at the University of Illinois at Chicago Health Sciences campus in a four month time frame. Many patients were underserved and underinsured, and we wanted to understand their experiences in the healthcare system. Using content analysis, several themes emerged from the interview data. Participants discussed the need for empathy and rapport with their providers. They identified provider behaviors that fostered a positive clinical relationship, including step-by step explanations of procedures, attention to body language and clinic atmosphere, and appropriate time management. Participants identified cost as the most common barrier to engaging in preventive care and discussed children and social support as motivating factors. A long-term relationship with a provider was an important motivator for preventive care, suggesting that the therapeutic alliance was essential to many patients. Conversely, many participants discussed a sense of dehumanization in the healthcare system, reporting that their life circumstances were overlooked, or that they were judged based on insurance status or ethnicity. We discuss implications for provider training and healthcare delivery, including the importance of patient-centered medical homes.

    Full Text Available Abstract Background Legionella species cause severe forms of pneumonia with high mortality and complication rates. Accurate clinical predictors to assess the likelihood of Legionella community-acquired pneumonia (CAP in patients presenting to the emergency department are lacking. Methods We retrospectively compared clinical and laboratory data of 82 consecutive patients with Legionella CAP with 368 consecutive patients with non-Legionella CAP included in two studies at the same institution. Results In multivariate logistic regression analysis we identified six parameters, namely high body temperature (OR 1.67, p Legionella CAP. Using optimal cut off values of these six parameters, we calculated a diagnostic score for Legionella CAP. The median score was significantly higher in Legionella CAP as compared to patients without Legionella (4 (IQR 3–4 vs 2 (IQR 1–2, p Legionella pneumonia. Conversely, of the 73 patients (16% with ≥4 points, 66% of patients had Legionella CAP. Conclusion Six clinical and laboratory parameters embedded in a simple diagnostic score accurately identified patients with Legionella CAP. If validated in future studies, this score might aid in the management of suspected Legionella CAP.

    Full Text Available Abstract Introduction The incidence of achondroplasia is very low, and the birth of two or more consecutive babies with achondroplasia to unaffected parents is a rarity. We report a rare case of recurrent achondroplasia in babies of unaffected parents. Case presentation A 29-year-old Nigerian Igbo woman who has had three consecutive dead achondroplastic babies presented at a gestational age of 31 weeks with a two-hour history of drainage of liquor and vaginal bleeding. Neither she nor her husband had features of achondroplasia. Fundal height was compatible with the gestational age. Fetal heart activity was present. An abdominal ultrasound examination showed a viable fetus with short long bones, oligohydramnios, and a fundal placenta with a small retroplacental blood clot. Our patient was stabilized and had an emergency Cesarean section for grade 1 abruptio placentae. A live male baby with Apgar scores of 4 at one minute and 5 at 10 minutes was delivered. The baby had classic features of achondroplasia and died shortly after birth. Conclusions To the best of our knowledge, this is the first reported case of recurrent achondroplasia in siblings of unaffected parents in Nigeria. Management is challenging, and the outcomes of future pregnancies appear bleak. However, proper counseling and follow-up are needed. There is also a need to establish preconception clinics and facilities for prenatal genetic diagnosis and gene therapy in developing countries.

    The first aim of this study was to evaluate combination antiemetic therapy consisting of 5-HT 3 receptor antagonists, neurokinin-1 receptor antagonists (NK-1RAs), and dexamethasone for multiple high emetogenic risk (HER) anticancer agents in bone and soft tissue sarcoma. The second aim was to compare the effectiveness of single-shot palonosetron and consecutive-day granisetron in a randomized, single-blinded crossover study. A single randomization method was used to assign eligible patients to the palonosetron or granisetron arm. Patients in the palonosetron arm received a palonosetron regimen during the first and third chemotherapy courses and a granisetron regimen during the second and fourth courses. All patients received NK-1RA and dexamethasone. Patients receiving the palonosetron regimen were administered 0.75 mg palonosetron on day 1, and patients receiving the granisetron regimen were administered 3 mg granisetron twice daily on days 1 through 5. All 24 patients in this study received at least 4 chemotherapy courses. A total of 96 courses of antiemetic therapy were evaluated. Overall, the complete response CR rate (no emetic episodes and no rescue medication use) was 34%, while the total control rate (a CR plus no nausea) was 7%. No significant differences were observed between single-shot palonosetron and consecutive-day granisetron. Antiemetic therapy with a 3-drug combination was not sufficient to control chemotherapy-induced nausea and vomiting (CINV) during chemotherapy with multiple HER agents for bone and soft tissue sarcoma. This study also demonstrated that consecutive-day granisetron was not inferior to single-shot palonosetron for treating CINV

    To determine the malignancy rate of nonpalpable breast lesions, categorised according to the Breast Imaging Reporting and Data System (BI-RADS) classification in the setting of a Breast Care Unit. All nonpalpable breast lesions from consecutive patients referred to a dedicated Breast Care Unit were prospectively reviewed and classified into 5 BI-RADS assessment categories (0, 2, 3, 4, and 5). A total of 2708 lesions were diagnosed by mammography (71.6%), ultrasound (8.7%), mammography and ultrasound (19.5%), or MRI (0.2%). The distribution of the lesions by BI-RADS category was: 152 in category 0 (5.6%), 56 in category 2 (2.1%), 742 in category 3 (27.4%), 1523 in category 4 (56.2%) and 235 in category 5 (8.7%). Histology revealed 570 malignant lesions (32.9%), 152 high-risk lesions (8.8%), and 1010 benign lesions (58.3%). Malignancy was detected in 17 (2.3%) category 3 lesions, 364 (23.9%) category 4 lesions and 185 (78.7%) category 5 lesions. Median follow-up was 36.9 months. This pragmatic study reflects the assessment and management of breast impalpable abnormalities referred for care to a specialized Breast Unit. Multidisciplinary evaluation with BI-RADS classification accurately predicts malignancy, and reflects the quality of management. This assessment should be encouraged in community practice appraisal.

    Pharmacy services are offered to patients, and often, they decline participation. Research is needed to better understand patients' unmet needs when taking prescribed medications. To identify and characterize patients' unmet needs related to using prescribed medication for chronic conditions. Focus groups of patients using prescription medication for chronic conditions discussed their experiences with medications, starting from initial diagnosis to ongoing management. Sessions involved 40 patients from 1 Midwestern U.S. state. Major themes were identified using content analysis. Three major themes emerged. First, patients seek information to understand their health condition and treatment rationale. Patients form an illness perception (its consequence, controllability, cause, and duration) that dictates their actions. Second, patients desire to be involved in treatment decisions, and they often feel that decisions are made for them without their understanding of the risk-to-benefit trade-off. Third, patients monitor the impact of treatment decisions to determine if anticipated outcomes are achieved. The results were consistent with Dowell's therapeutic alliance model (TAM) and Leventhal's common sense model (CSM). The TAM can be used to model the consultative services between pharmacists and patients. The impact of the new services (or interventions) can be evaluated using the CSM. Patients expressed a strong desire to be involved in their treatment decisions. The effectiveness of medication therapy management services may be enhanced if pharmacists build on patients' desire to be involved in their treatment decisions and assist them to understand the role of medications and their risks and expected outcomes within the context of the patients' perceptions of illness and desired coping strategies.

    Phase I clinical trials are the gateway to effective new cancer treatments. Many physicians have difficulty when discussing Phase I clinical trials. Research demonstrates evidence of suboptimal communication. Little is known about communication strategies used by oncologists when recruiting patients for Phase I trials. We analyzed audio recorded Phase I consultations to identify oncologists' communication strategies. Subjects were consecutive cancer patients from six medical oncologists attending one of three outpatient clinics at a major Cancer Center in the United States. Sixteen patients signed informed consent for audio recording of their consultations in which a Phase I study was discussed. These were transcribed in full and analyzed to identify communication strategies. Six communication themes emerged from the analysis: (1) orienting, (2) educating patients, (3) describing uncertainty and prognosis, (4) persuading, (5) decision making, and (6) making a treatment recommendation. As expected, although there was some common ground between communication in Phase I and the Phase II and III settings, there were distinct differences. Oncologists used persuasive communication, made explicit recommendations, or implicitly expressed a treatment preference and were choice limiting. This highlights the complexity of discussing Phase I trials and the need to develop strategies to aid oncologists and patients in these difficult conversations. Patient centered communication that values patient preferences while preserving the oncologist's agenda can be a helpful approach to these discussions. Copyright © 2010 John Wiley & Sons, Ltd.

    Urinary tract infections (UTIs) are among the most common bacterial infections in men and urine culture is gold standard for diagnosis. Considering the high prevalence of culture-negative specimens, any method that identifies such specimens is of interest. The aim was to evaluate a new screening concept for flow cytometry analysis (FCA). The outcomes were evaluated against urine culture, uropathogen species and three conventional screening methods. A prospective, consecutive study examined 1,312 urine specimens, collected during January and February 2012. The specimens were analyzed using the Sysmex UF1000i FCA. Based on the FCA data culture negative specimens were identified in a new model by use of linear discriminant analysis (FCA-LDA). In total 1,312 patients were included. In- and outpatients represented 19.6% and 79.4%, respectively; 68.3% of the specimens originated from women. Of the 610 culture-positive specimens, Escherichia coli represented 64%, enterococci 8% and Klebsiella spp. 7%. Screening with FCA-LDA at 95% sensitivity identified 42% (552/1312) as culture negative specimens when UTI was defined according to European guidelines. The proposed screening method was either superior or similar in comparison to the three conventional screening methods. In conclusion, the proposed/suggested and new FCA-LDA screening method was superior or similar to three conventional screening methods. We recommend the proposed screening method to be used in clinic to exclude culture negative specimens, to reduce workload, costs and the turnaround time. In addition, the FCA data may add information that enhance handling and support diagnosis of patients with suspected UTI pending urine culture [corrected].

    We examined the effects of treatment on the psychological well-being of patients with localized or advanced penile cancer using screening questionnaires to determine the consecutive need for psychosocial care. Penile cancer is a rare, but highly aggressive, malignancy. The psychological stress of patients with penile cancer arises from the cancer diagnosis per se and the corresponding consequences of treatment. In addition, cancer-specific distress results (eg, fear of metastasis, progression, relapse, death). Studies of the psychosocial stress of penile cancer patients are rare. We undertook a prospective analysis of the data from patients with penile cancer who had undergone surgery or chemotherapy from August 2014 to October 2016 at our department. Patients were evaluated using standardized questionnaires for stress screening and the identification for the need for psychosocial care (National Comprehensive Cancer Network Distress Thermometer and Hornheider screening instrument) and by assessing the actual use of psychosocial support. The average stress level was 4.5. Of all the patients, 42.5% showed increased care needs at the time of the survey. Younger patients, patients undergoing chemotherapy, and patients with recurrence were significantly more integrated with the psychosocial care systems. Finally, 67% of all patients received inpatient psychosocial care. Owing to the potentially mutilating surgery, patients with penile cancer experience increased psychological stress and, consequently, have an increased need for psychosocial care. Therefore, the emotional stress of these patients should be recognized and support based on interdisciplinary collaboration offered. Copyright © 2017 Elsevier Inc. All rights reserved.

    Postactivation potentiation (PAP) and complex training have generated interest within the strength and conditioning community in recent years, but much of the research to date has produced confounding results. The purpose of this study was to observe the acute effects of a heavy-load back squat [85% 1 repetition maximum (1RM)] condition on consecutive squat jump performance. Twelve in-season Division I male track-and-field athletes participated in two randomized testing conditions: a five-repetition back squat at 85% 1RM (BS) and a five-repetition squat jump (SJ). The BS condition consisted of seven consecutive squat jumps (BS-PRE), followed by five repetitions of the BS at 85% 1RM, followed by another set of seven consecutive squat jumps (BS-POST). The SJ condition was exactly the same as the BS condition except that five consecutive SJs replaced the five BSs, with 3 minutes' rest between each set. BS-PRE, BS-POST, SJ-PRE, and SJ-POST were analyzed and compared for mean and peak jump height, as well as mean and peak ground reaction force (GRF). The BS condition's mean and peak jump height and peak GRF increased 5.8% +/- 4.8%, 4.7% +/- 4.8%, and 4.6% +/- 7.4%, respectively, whereas the SJ condition's mean and peak jump height and peak GRF decreased 2.7% +/- 5.0%, 4.0% +/- 4.9%, and 1.3% +/- 7.5%, respectively. The results indicate that performing a heavy-load back squat before a set of consecutive SJs may enhance acute performance in average and peak jump height, as well as peak GRF.

    Whereas the literature is replete with reports on complex children with dysphagia (DP), the parameters characterizing non-neurologically impaired (NNI) children have been underreported, leaving a substantial knowledge gap. We set to characterize a consecutive cohort of NNI children, their management, and outcomes. We undertook a retrospective case series. Children (<18 years old) attending a tertiary multidisciplinary swallowing clinic were eligible. Patients with neuro-developmental, neuromuscular, or syndromic abnormalities were excluded. Primary outcomes included demographics, co-morbidities, presentations, McGill score, swallowing and airway abnormalities (and their predictors). Secondary outcomes were interventions and management response. From 171 consecutive patients (37-month period), 128 were included (69 males, median age 6.6 months (0.5-124.2)). Significant clinical presentations included recurrent pneumonias (20), cyanotic spells (14) and life-threatening events (10). Swallowing assessments revealed laryngeal penetration (67), aspiration (25). Other investigations included overnight oximetry (77), airway (70), and gastrointestinal endoscopy (24); revealing laryngomalacia (29), laryngeal mobility disorder (8), and subglottic stenosis (8). Non-surgical interventions involved oral diet modifications (85) and enteral nutrition (15). Surgical interventions included supraglottoplasties (18), endoscopic laryngeal cleft repair (14), and injection (19). 119 patients received intervention and at last follow-up (median 5.2 months (0.3-88.8)) 94 had improved. Of those treated 116 were on an unmodified oral diet, and 24 on a modified diet. ALTE and snoring predicted airway abnormalities, recurrent pneumonia predicted swallowing abnormalities, and age and airway lesions predicted the McGill score. a significant proportion of NNI children with DP harbor airway and swallowing abnormalities warranting endoscopic and instrumental assessment.

    There is only sparse data on clinical results and complications of the third-generation Gamma nailing system (Gamma3, Stryker). Therefore, we started a large multi-centre case series in 2008. The aim of this paper is to present the study design and early results of a single arm of a prospective, consecutive, monitored, post-market follow-up evaluation of Gamma3 nails. From September 2009 to January 2012, 154 consecutive patients with an average age of 80 ± 1.43 years (50-99 years) and a trochanteric femoral fracture were included in the local arm of the trial. All patients that fulfilled the inclusion criteria were treated with a Gamma3 nail. Preoperative variables included age, gender, fracture classification, walking ability (Merle d'Aubigné score), daily activity level (retrospective Zuckerman score), ASA rating of operative risk, waiting time for operation, use of walker or crutches and body mass index (BMI). Skin-to-skin time, fluoroscopy time, blood loss, intraoperative complications and device information were recorded for each patient. Follow-up postoperative assessment was undertaken at 4, 12 and 24 months. Hip range of motion, pain around the hip and the tight, walking ability (Merle d'Aubigné score, Sahlgrenska mobility score) and management of daily life (Zuckerman score) were used to evaluate the outcome. The descriptive data of age, gender, BMI, ASA classification, fracture type and skin-to-skin time is similar to other studies. Median fluoroscopy time was 62 seconds (range: 4-225 seconds) and significantly shorter in closed reductions. No intraoperative implant-related complication was recorded. A cut-out of the leg-screw during assessment period occurred in 2.6% patients (n = 4). At the 12-month assessment two (1.8%) non-unions were identified and two patients (1.8%) had broken the femoral shaft below the 180 mm nail after a fall. Analysis of the scores showed significantly declined mobility and activity in daily life four months after operation

    Full Text Available Abstract Background Fixation of trochanteric hip fractures using the Gamma Nail has been performed since 1988 and is today well established and wide-spread. However, a number of reports have raised serious concerns about the implant's complication rate. The main focus has been the increased risk of a subsequent femoral shaft fracture and some authors have argued against its use despite other obvious advantages, when this implant is employed. Through access to a uniquely large patient data base available, which is available for analysis of trochanteric fractures; we have been able to evaluate the performance of the Gamma Nail over a twelve year period. Methods 3066 consecutive patients were treated for trochanteric fractures using Gamma Nails between 1990 and 2002 at the Centre de Traumatologie et de l'Orthopedie (CTO, Strasbourg, France. These patients were retrospectively analysed. Information on epidemiological data, intra- and postoperative complications and patients' outcome was retrieved from patient notes. All available radiographs were assessed by a single reviewer (AJB. Results The results showed a low complication rate with the use of the Gamma Nail. There were 137 (4.5% intraoperative fracture-related complications. Moreover 189 (6.2% complications were detected postoperatively and during follow-up. Cut-out of the lag screw from the femoral head was the most frequent mechanical complication (57 patients, 1.85%, whereas a postoperative femoral shaft fracture occurred in 19 patients (0.6%. Other complications, such as infection, delayed healing/non-union, avascular femoral head necrosis and distal locking problems occurred in 113 patients (3.7%. Conclusions The use of the Gamma Nail in trochanteric hip fractures is a safe method with a low complication rate. In particular, a low rate of femoral shaft fractures was reported. The low complication rate reported in this series can probably be explained by strict adherence to a proper

  6. A Case Of Invasive Aspergillosis In A Patient With No identifiable Immunodeficiencies

    2008-01-01

    Full Text Available Invasive fungal infections usually affect patients with immunodeficiencies and very rarely patients with no known or identifiable risk factors. Diagnosis could be delayed in patients without previously known immunodeficiencies due to a low index of suspicion, leading to a delay in treatment and a potential poor outcome. We report a case of a postpartum woman with no history of immuno-compromised disease who developed left hemiparesis with evidence of invasive aspergollosis affecting the nervous system, and leading to fatal outcome. The patient had a mass-like lesion in the neuroimaging with soft tissue shadowing in the chest x-ray leading to initial diagnosis of tuberculosis. The brain biopsy showed changes consistent with a diagnosis of aspergillosis. The source of the aspergillus infection was not clear. Aspergillus infection should be considered in patients with no identifiable immunodeficiencies who have abnormal brain imaging and chest x-ray, as early treatment may alter the outcome.

    Choledocholithiasis is a real problem of major clinical importance. The incidence of cholelithiasis is 10-20%. We have examined 2907 patients treated with videolaparoscopic cholecystectomy (VLC) between January 2001 and September 2009. 214 cases (7.4%) were affected by choledocolithiasis; among these, 59 consecutive cases were treated by rendezvous, 151 cases by sequential treatment (ERCP-ES before VLC), 3 cases by extraction with Dormia's basket, and 1 case by ERCP-ES after VLC. The complications were one biliary fistula and three hemorrhages (one from the cystic artery, one from the hepatic area and one from trocar's site). The mean hospital stay was 1.38 +/- 0.83 days for the rendezvous group vs 4 53 +/- 0.74 days in the sequential treatment group (prendezvous procedure reduces hospital stay and has a greater compliance (only one treatment). We can use this option in the management of cases where preoperative ERCP-ES has failed.

    Left atrial (LA) tissue characteristics may play an important role in atrial fibrillation (AF) induction and perpetuation. Although frequently used in clinical practice, computed tomography (CT) has not been employed to describe differences in LA wall properties between AF patients and controls. We sought to noninvasively characterize AF-associated differences in LA tissue using CT. CT images of the LA were obtained in 98 consecutive patients undergoing AF ablation and in 89 controls. A custom software algorithm was used to measure wall thickness and density in four prespecified regions of the LA. On average, LA walls were thinner (-15.5%, 95% confidence interval [CI] -23.2 to -7.8%, P identified significant thinning of the LA wall and regional alterations in tissue density in patients with a history of AF. These findings suggest differences in LA tissue composition can be noninvasively identified and quantified using CT. ©2012, The Authors. Journal compilation ©2012 Wiley Periodicals, Inc.

    The objective of this study was to evaluate outcomes of endoscopic transsphenoidal surgery using a single-surgeon technique as an alternative to the more commonly employed two-surgeon, three-hand method. Three hundred consecutive endoscopic transsphenoidal procedures performed over a 5 year period from 2006 to 2011 were reviewed. All procedures were performed via a binasal approach utilizing a single surgeon two handed technique with a pneumatic endoscope holder. Expanded enodnansal cases were excluded. Surgical technique, biochemical and surgical outcomes, and complications were analyzed. 276 patients underwent 300 consecutive surgeries with a mean follow-up period of 37 ± 22 months. Non-functioning pituitary adenoma (NFPA) was the most common pathology (n = 152), followed by growth hormone secreting tumors (n = 41) and Rathke's cleft cysts (n = 30). Initial gross total cyst drainage based on radiologic criteria was obtained in 28 cases of Rathke's cleft cyst, with 5 recurrences. For NFPA and other pathologies (n = 173) gross total resection was obtained in 137 cases, with a 92% concordance rate between observed and expected extent of resection. For functional adenoma, remission rates were 30/41 (73%) for GH-secreting, 12/12 (100%) for ACTH-secreting, and 8/17 (47%) for prolactin-secreting tumors. Post-operative complications included transient (11%) and permanent (1.4%) diabetes insipidus, hyponatremia (13%), and new anterior pituitary hormonal deficits (1.4%). CSF leak occurred in 42 cases (15%), and four patients required surgical repair. Two carotid artery injuries occurred, both early in the series. Epistaxis and other rhinological complications were noted in 10% of patients, most of which were minor and diminished as surgical experience increased. Fully endoscopic single surgeon transsphenoidal surgery utilizing a binasal approach and a pneumatic endoscope holder yields outcomes comparable to those reported with a two-surgeon method.

    The first aim of this study was to evaluate combination antiemetic therapy consisting of 5-HT3 receptor antagonists, neurokinin-1 receptor antagonists (NK-1RAs), and dexamethasone for multiple high emetogenic risk (HER) anticancer agents in bone and soft tissue sarcoma. The second aim was to compare the effectiveness of single-shot palonosetron and consecutive-day granisetron in a randomized, single-blinded crossover study. A single randomization method was used to assign eligible patients to the palonosetron or granisetron arm. Patients in the palonosetron arm received a palonosetron regimen during the first and third chemotherapy courses and a granisetron regimen during the second and fourth courses. All patients received NK-1RA and dexamethasone. Patients receiving the palonosetron regimen were administered 0.75 mg palonosetron on day 1, and patients receiving the granisetron regimen were administered 3 mg granisetron twice daily on days 1 through 5. All 24 patients in this study received at least 4 chemotherapy courses. A total of 96 courses of antiemetic therapy were evaluated. Overall, the complete response CR rate (no emetic episodes and no rescue medication use) was 34%, while the total control rate (a CR plus no nausea) was 7%. No significant differences were observed between single-shot palonosetron and consecutive-day granisetron. Antiemetic therapy with a 3-drug combination was not sufficient to control chemotherapy-induced nausea and vomiting (CINV) during chemotherapy with multiple HER agents for bone and soft tissue sarcoma. This study also demonstrated that consecutive-day granisetron was not inferior to single-shot palonosetron for treating CINV. © 2014 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Hepatectomies have been increasingly recommended and performed in Brazil; they present great differences related to immediate complications. Assessing the immediate postoperative complications in a series of 88 open liver resections. Prospective database of patients subjected to consecutive hepatectomies over nine years. The post-hepatectomy complications were categorized according to the Clavien-Dindo classification; complications presenting grade equal to or greater than 3 were considered major complications. Hepatic resections involving three or more resected liver segments were considered major hepatectomies. Eighty-four patients were subjected to 88 hepatectomies, mostly were minor liver resections (50 cases, 56.8%). Most patients had malignant diseases (63 cases; 71.6%). The mean hospitalization time was 10.9 days (4-43). Overall morbidity and mortality rates were 37.5% and 6.8%, respectively. The two most common immediate general complications were intra-peritoneal collections (12.5%) and pleural effusion (12.5%). Bleeding, biliary fistula and liver failure were identified in 6.8%, 4.5% and 1.1% of the cases, respectively, among the hepatectomy-specific complications. The patients operated in the second half of the series showed better results, which were apparently influenced by the increased surgical expertise, by the modification of the hepatic parenchyma section method and by the increased organ preservation. No Brasil as hepatectomias têm sido cada vez mais indicadas e realizadas, apresentando grandes diferenças relacionadas às complicações imediatas. Avaliar as complicações pós-operatórias imediatas em uma série de 88 ressecções hepáticas abertas. Foi utilizada uma base de dados prospectiva de pacientes submetidos à hepatectomias consecutivas em nove anos.

    Purpose: To describe radiation therapy cases during which voluntary incident reporting occurred; and identify patient- or treatment-specific factors that place patients at higher risk for incidents. Methods and Materials: We used our institution's incident learning system to build a database of patients with incident reports filed between January 2011 and December 2013. Patient- and treatment-specific data were reviewed for all patients with reported incidents, which were classified by step in the process and root cause. A control group of patients without events was generated for comparison. Summary statistics, likelihood ratios, and mixed-effect logistic regression models were used for group comparisons. Results: The incident and control groups comprised 794 and 499 patients, respectively. Common root causes included documentation errors (26.5%), communication (22.5%), technical treatment planning (37.5%), and technical treatment delivery (13.5%). Incidents were more frequently reported in minors (age <18 years) than in adult patients (37.7% vs 0.4%, P<.001). Patients with head and neck (16% vs 8%, P<.001) and breast (20% vs 15%, P=.03) primaries more frequently had incidents, whereas brain (18% vs 24%, P=.008) primaries were less frequent. Larger tumors (17% vs 10% had T4 lesions, P=.02), and cases on protocol (9% vs 5%, P=.005) or with intensity modulated radiation therapy/image guided intensity modulated radiation therapy (52% vs 43%, P=.001) were more likely to have incidents. Conclusions: We found several treatment- and patient-specific variables associated with incidents. These factors should be considered by treatment teams at the time of peer review to identify patients at higher risk. Larger datasets are required to recommend changes in care process standards, to minimize safety risks.

    Full Text Available Clinically significant bleeding is important for subsequent optimal case management in dengue patients, but most studies have focused on dengue severity as an outcome. Our study objective was to identify differences in admission parameters between patients who developed clinically significant bleeding and those that did not. We sought to develop a model for discriminating between these patients.We conducted a retrospective study of 4,383 adults aged >18 years who were hospitalized with dengue infection at Tan Tock Seng Hospital, Singapore from 2005 to 2008. Patients were divided into those with clinically significant bleeding (n = 188, and those without (n = 4,195. Demographic, clinical, and laboratory variables on admission were compared between groups to determine factors associated with clinically significant bleeding during hospitalization.On admission, female gender (p38°C (p38°C (aOR 1.81; 95% CI: 1.27-2.61, nausea/vomiting (aOR 1.39; 95% CI: 0.94-2.12, ANC (aOR 1.3; 95% CI: 1.15-1.46, ALC (aOR 0.4; 95% CI: 0.25-0.64, hematocrit percentage (aOR 0.96; 95% CI: 0.92-1.002 and platelet count (aOR 0.993; 95% CI: 0.988-0.998. At the cutoff of -3.919, the model achieved an AUC of 0.758 (sensitivity:0.87, specificity: 0.38, PPV: 0.06, NPV: 0.98.Clinical risk factors associated with clinically significant bleeding were identified. This model may be useful to complement clinical judgement in triaging adult dengue patients given the dynamic nature of acute dengue, particularly in pre-identifying those less likely to develop clinically significant bleeding.

    Immediate placement of implants in extraction sockets for early loading is an attractive treatment modality due to reduced treatment time. However, the outcome of fluoridated implants in this situation with regard to bone levels and health of soft tissues is not well documented. To evaluate the outcome of early loading of OsseoSpeed(™) dental implants placed into fresh extraction sockets and healed bone in consecutive patients treated in a private clinic. A total of 182 OsseoSpeed(™) implants (Astra Tech Implant System, DENTSPLY Implants, Mölndal, Sweden), 72 in immediate extraction sockets and 110 in healed sites, were placed in 39 consecutive patients. The implants were loaded with permanent restorations within 60 days (average 31 days). Clinical and radiographic follow-up examinations were performed annually for at least 3 years (mean 55 months). An aesthetic index was used to evaluate the soft tissues adjacent to the prosthetic restorations. No implant was lost during the observation period, giving a survival rate of 100%. Bone level changes during the observation period were minimal, with a mean marginal bone loss of 0.3 ± 0.9 mm around the delayed implants and a mean marginal bone gain of 0.3 ± 1.4 mm around the immediate implants (p = .0036). The frequency distribution of bone level revealed that 85% of implants placed in fresh extraction sockets and 84% of implants in healed bone did not show any loss of bone level during follow-up (p = NS). Soft tissue complications were observed at two immediate implant sites in one patient. The remaining 180 implants received the highest aesthetic score. Moreover, no signs of peri-implant purulent infection or aggressive bone loss were found during the follow-up period. Early loading of fluoridated implants with permanent constructions appears to be a viable therapy for implants placed immediately in extraction sites and in healed bone. © 2014 Wiley Periodicals, Inc.

    Problems in the structure, consistency, and completeness of electronic health record data are barriers to outcomes research, quality improvement, and practice redesign. This nonexperimental retrospective study examines the utility of importing de-identified electronic health record data into an external system to identify patients with and at risk for essential hypertension. We find a statistically significant increase in cases based on combined use of diagnostic and free-text coding (mean = 1,256.1, 95% CI 1,232.3-1,279.7) compared to diagnostic coding alone (mean = 1,174.5, 95% CI 1,150.5-1,198.3). While it is not surprising that significantly more patients are identified when broadening search criteria, the implications are critical for quality of care, the movement toward the National Committee for Quality Assurance's Patient-Centered Medical Home program, and meaningful use of electronic health records. Further, we find a statistically significant increase in potential cases based on the last two or more blood pressure readings greater than or equal to 140/90 mm Hg (mean = 1,353.9, 95% CI 1,329.9-1,377.9).

    The aim of the present investigation was to elucidate in a large consecutive patient cohort whether the level of training has an effect on the number of microemboli detected by diffusion-weighted imaging (DWI) and which additional risk factors can be identified. A total of 107 consecutive patients in whom a diagnostic cerebral angiography had been performed were prospectively investigated with DWI; 51 angiographies were performed by experienced neuroradiologists, 56 by neuroradiologists in training. In 12 patients (11.1%), a total of 17 new lesions without any clinically overt neurological symptoms were identified. Of these, 12 patients, 11 (91.7%) with 16 lesions were investigated by junior neuroradiologists. In 11 of 12 patients with DWI abnormalities (91.7%), risk factors could be identified (atherosclerotic vessel wall disease, vasculitis, hypercoagulable states). Experienced neuroradiologists performed 21 of 48 angiographies (43.8%) on patients with the above-mentioned risk factors, whereas junior neuroradiologists performed 27 angiographies in this subgroup (46.2%). The rate of diffusion abnormalities in patients with risk factors was 11/48 (22.9%) - considerably higher than in patients without risk factors (1/59; 1.7%). The level of experience and the nature of the underlying disease are predictors of the occurrence of cerebral ischemic events following neuroangiography. Alternative diagnostic modalities should be employed in patients who are investigated for diseases with the highest risk of angiographic complications (i.e., vasculitis, and arteriosclerotic vessel wall disease). If diagnostic angiography remains necessary in these patients, the highest level of practitioner training is necessary to ensure good patient outcome. (orig.)

    The purpose of this article is to evaluate the timing for three-dimensional (3D) virtual treatment planning of orthognathic surgery in the daily clinical routine. A total of 350 consecutive patients were included in this study. All patients were scanned following the standardized "Triple CBCT Scan Protocol" in centric relation. Integrated 3D virtual planning and actual surgery were performed by the same surgeon in all patients. Although clinically acceptable, still software improvements especially toward 3D virtual occlusal definition are mandatory to make 3D virtual planning of orthognathic surgery less time-consuming and more user-friendly to the clinician.

    2017-01-01

    Full Text Available The dysplasia epiphysealis hemimelica (DEH is a rare disease of unknown etiology consisting in an abnormal osteocartilaginous growth at the epiphysis, usually hemimelic with histological findings similar to benign osteochondroma. In this case series, we described the results of the arthroscopic treatment of 2 consecutive cases of intra-articular ankle localization of DEH in 2 patients aged 9 and 10 years. The good result obtained, persistent at the 5-year follow-up, leads us to consider the arthroscopic approach as a reliable treatment in patient affected by intra-articular ankle DEH.

    2013-01-01

    Objective To analyze the characteristics of patients who needed a blood transfusion due to epistaxis-caused anemia and to define potential risk factors. Design Retrospective cohort study. Setting A total cohort of 591 epistaxis patients, prospectively included between March 2007 and April 2008 at the ENT department of the University Hospital of Zurich, was evaluated concerning the need for blood transfusions. Methods The clinical charts and medical histories of these patients were evaluated. Main outcome measures Common parameters that increase the risk for severe anemia due to epistaxis. Results Twenty-two patients required blood transfusions due to their medical condition. 22.7% suffered from traumatic nosebleeds. Another 27.3% had a known medical condition with an increased bleeding tendency. These proportions were significantly higher than in the group of patients without need of blood transfusion. The odds ratio for receiving a blood transfusion was 14.0 in patients with hematologic disorders, 4.3 in traumatic epistaxis and 7.7 in posterior bleeders. The transfusion-dependent epistaxis patients suffered significantly more often from severe posterior nosebleeds with the need for a surgical therapeutic approach. Conclusions Patients with severe nosebleeds either from the posterior part of the nose or with known hematologic disorders or traumatic epistaxis should be closely monitored by blood parameter analyses to evaluate the indication for hemotransfusion. The acronym THREAT (Trauma, Hematologic disorder, and REAr origin of bleeding → Transfusion) helps to remember and identify the factors associated with an increased risk of receiving blood transfusion.

    There have been previous reports describing patients with lumbar stenosis (LS) in West Africa; however, to date no such report has been published from Ghana. To provide data on the pattern of lumbar stenosis and the effects of decompressive lumbar laminectomy (DLL) on the clinical course of LS in Tema. Sixty-five consecutive patients who underwent DLL for lumbar stenosis over between January 2001 and December 2004 had their medical records analyzed. The parameters of interest included demographics, pre and post surgical clinical status utilizing the modified low back pain clinical scoring system, operative procedure and complications. Sixty-five patients (36M, 29F) with a mean age of 51 years constituted the series. All had failed conservative treatment; each patient was operated on once at our institution. Eighty nine percent of the series presented with neurogenic claudication and accompanying motor and sensory deficits. Twenty-seven patients (41.5%) underwent bilateral DLL; the rest underwent unilateral DLL. The mean preoperative score for the series was 2.3; that for males 2.6, females 1.9 (p > 0.05). There was a significant difference between patients 60 years. The mean postoperative score for the series was 8.7. There was a significant difference between preoperative and postoperative scores of series. No mortality was recorded The complication rate was 15%. In Tema, decompressive lumbar laminectomy for lumbar stenosis achieves significant clinical improvement with attendant low morbidity and mortality rates in patients who have failed conservative treatment. Accompanying disc excision and or fusion are required in only a small minority of patients.

    Objective: To categorize the significant complications occurred in the perioperative period of peripheral vascular interventions and to analyze their causes, outcomes and managements in order to make a further understanding of the cause of occurrence and to improve the handling ability. Methods: Over the past five years a total of 1620 consecutive peripheral vascular interventions were carried out in our institute. Significant complications, which occurred in the perioperative period, and the clinical data were carefully examined. The occurrence, treatment, consequence and final outcome of each complication were retrospectively analyzed. Results: Of 1620 consecutive peripheral interventional procedures, significant complication which developed during the operation or within one week after the treatment was seen in 76 (4.69%). The significant complications could be classified into twelve kinds. After proper management most complications were cured without leaving any sequelae. Nevertheless, in some patients permanent damages such as paraplegia, lower limb paralysis, necrosis of gluteus, etc. were left over. Death occurred in six patients. Of the six patients, four died of concomitant hepatic failure and agranulocytosis, one of retroperitoneal hematoma and hemoperitoneum, and another one of pulmonary embolism. Conclusion: (1) Significant complications may occur in most peripheral vascular interventional therapies, which, in most cases, are mainly related to the insufficient understanding of the disease and improper manipulation. (2) A comprehensive and solid fundamental knowledge of the disease, strictly following the indications and careful handling the operation are the key points to reduce the occurrence of severe complications in the perioperative period of peripheral vascular interventions.

    Endovascular coiling of intracranial aneurysms carries a risk of complications. Early detection and management of complications can improve clinical outcomes. AngioCT is a new imaging technology enabling CT-like images to be generated on a flat-panel digital subtraction angiography system, which can provide immediate ''on angio table'' identification and thorough assessment of such complications. We prospectively audited its utility during aneurysm coiling in patients following subarachnoid haemorrhage (SAH). A prospective series of 44 patients with SAH undergoing endovascular coiling with AngioCT was audited for image quality and the influence of the AngioCT on patient management. In a parallel experimental study, radiation doses were measured and image quality parameters on standard phantoms were established. In all patients, AngioCT provided adequate diagnostic information. In 40.9% of patients, AngioCT was a substantial or major factor in determining the management immediately after coiling. Using a 10-s high-dose acquisition technique, acceptable image quality could be obtained rapidly with a radiation dose just over half that for a conventional CT scan of the head (35 mGy versus approximately 60 mGy). No patient in this series required conventional CT to clarify the AngioCT appearance. AngioCT has many applications in the neurointerventional setting. In particular during coiling, AngioCT provides a rapid way to clarify concerns or identify complications and in some cases was the major factor influencing further patient management immediately after coiling. AngioCT images were judged of adequate quality to be clinically useful in all patients in this series. (orig.)

    To evaluate the dental arch relationships for a consecutive series from Goteborg, Sweden, who had delayed hard palate closure. Retrospective study. Sahlgrenska University Hospital, Goteborg, Sweden. The dental study models of 104 consecutive unilateral cleft lip and palate subjects. The study cohort was born between 1979 and 1994. Longitudinal records were available at ages 5 (n = 94), 10 (n = 97), 16 (n = 59), and 19 years (n = 46). Five assessors rated models according to the GOSLON Yardstick on two separate occasions each. These patients had been operated upon according to the Goteborg protocol of delayed hard palate closure (at age 8 years). 85% of subjects were rated in groups 1 and 2 (excellent or very good outcome), 12% were rated in group 3 (satisfactory), and 3% were assigned to group 4 (poor). No patients presented in Group 5 (very poor). Weighted kappa statistics for double determination of Yardstick allocation for five assessors demonstrated values between .65 and .90 for interrater agreement (good/very good) and between .70 and .90 for intrarater agreement (very good). Delayed hard palate closure as practiced in Goteborg since 1979 has produced the best GOSLON Yardstick ratings in a consecutive series of patients ever recorded worldwide, since the Yardstick was first used in 1983. However, it is noteworthy that a new protocol has been introduced in Goteborg since 1994, in which hard palate closure is done at 3 years due to concerns regarding speech.

    BACKGROUND: Reduction in consumption of opioid rescue medication is often used as an endpoint when investigating analgesic efficacy of drugs by adjunct treatment, but appropriate methods are needed to analyze analgesic consumption in time. Repeated time-to-event (RTTE) modeling is proposed as a way...... to describe analgesic consumption by analyzing the timing of consecutive analgesic events. METHODS: Retrospective data were obtained from 63 patients receiving standard analgesic treatment including morphine on request after surgery following hip fracture. Times of analgesic events up to 96 h after surgery...... were extracted from hospital medical records. Parametric RTTE analysis was performed with exponential, Weibull, or Gompertz distribution of analgesic events using NONMEM®, version 7.2 (ICON Development Solutions, USA). The potential influences of night versus day, sex, and age were investigated...

    Full Text Available Abstract Objective To compare outcomes between children ( Summary of background data Reported complication rates for children undergoing surgery for Graves’ disease are worse than for adults. Methods 100 consecutive patients (32 children; 68 adults who underwent total thyroidectomy for Graves’ disease (GD by a high-volume endocrine surgery team from were compared. Results The mean patient age was 9.7 yrs (range 3.4-17.9 yrs in children versus 44.9 yrs (range 18.4-84.2 yrs in adults. Operative times were longer in children (2.18 ± 0.08 hrs than in adults (1.66 ± 0.03 hrs (p = 0.003. Pediatric thyroid specimens averaged 38.6.0 ± 8.9 gm (range: 9–293 gm and adult thyroid specimens averaged 48.0 ± 6.4 gm (range: 6.6-203 gm (p = 0.34. Thyroid to body weight ratios were greater in children (0.94 ± 0.11 gm/kg than adults (0.67 ± 0.8 gm/kg (p = 0.05. In all patients, the hyperthyroid state resolved after surgery. There was no operative mortality, recurrence, or permanent hypoparathyroidism. Transient post-operative hypocalcemia requiring calcium infusion was greater in children than adults (6/32 vs. 1/68; p = 0.004. Transient recurrent laryngeal nerve dysfunction occurred in two children and in no adults (p = 0.32. Postoperative hematoma occurred in two adults and in no children (p = 0.46. The length of stay was longer for children (1.41 ± 0.12 days than for adults (1.03 ±0.03 days (p = 0.004. Conclusion Surgical management of GD is technically more challenging in children as evidenced by longer operative times. Whereas temporary hypocalcemia occurs more commonly in children than adults, the risks of major complications including disease recurrence, permanent hypoparathyroidism, recurrent laryngeal nerve injury, or neck hematoma were indistinguishable. These data suggest that excellent and equivalent outcomes can be achieved for GD surgery in children and adults when care is rendered

    Factors health providers face during the doctor-patient encounter both impede and assist the development of collaborative models of treatment. I investigated decision making among medical and therapeutic professionals who work with trans-identified patients to understand factors that might impede or facilitate the adoption of the collaborative decision-making model in their clinical work. Following a grounded theory approach, I collected and analysed data from semi-structured interviews with 10 U.S. physicians and 10 U.S. mental health professionals. Doctors and therapists often desire collaboration with their patients but experience dilemmas in treating the trans-identified patients. Dilemmas include lack of formal education, little to no institutional support and inconsistent understanding and application of the main documents used by professionals treating trans-patients. Providers face considerable risk in providing unconventional treatments due to the lack of institutional and academic support relating to the treatment for trans-people, and the varied interpretation and application of the diagnostic and treatment documents used in treating trans-people. To address this risk, the relationship with the patient becomes crucial. However, trust, a component required for collaboration, is thwarted when the patients feel obliged to present in ways aligned with these documents in order to receive desired treatments. When trust cannot be established, medical and mental health providers can and do delay or deny treatments, resulting in the imbalance of power between patient and provider. The documents created to assist in treatment actually thwart professional desire to work collaboratively with patients. © 2013 John Wiley & Sons Ltd.

    Full Text Available Setting: It is not known what the magnitude of non-identified TB contacts is in our country, or the reasons why contacts at risk are not identified. Objective: The purpose of this study was to analyze the determinants associated with non-identification of contacts. Design: This cross-sectional study included all cases of pulmonary tuberculosis diagnosed and treated in the Chest Disease Centre of Vila Nova de Gaia and their contacts, from 1st January to 31st December 2010. It included information collected from patients related to the identification of contacts in risk, and the information collected by the Public Health Unit during home, work and social places visits. Results: During the period of study, 61 cases of pulmonary TB were diagnosed: 41 cases (67.2% identified all their contacts and 20 cases (32.8% did not. 646 contacts were identified: 154 (23.8% were identified only by the Public Health Unit (mean age of 40.67, and 492 (76.2% were identified by the index cases (mean age of 33.25, (p = 0.001.

    Background: The cornerstone of hypersensitivity pneumonitis (HP) management is having patients avoid the inciting antigen (IA). Often, despite an exhaustive search, an IA cannot be found. The objective of this study was to examine whether identifying the IA impacts survival in patients with chronic HP. Methods: We used the Kaplan-Meier method to display, and the log-rank test to compare, survival curves of patients with well-characterized chronic HP stratified on identification of an IA exposure. A Cox proportional hazards (PH) model was used to identify independent predictors in time-to-death analysis. Results: Of 142 patients, 67 (47%) had an identified IA, and 75 (53%) had an unidentified IA. Compared with survivors, patients who died (n = 80, 56%) were older, more likely to have smoked, had lower total lung capacity % predicted and FVC % predicted, had higher severity of dyspnea, were more likely to have pulmonary fibrosis, and were less likely to have an identifiable IA. In a Cox PH model, the inability to identify an IA (hazard ratio [HR], 1.76; 95% CI, 1.01-3.07), older age (HR, 1.04; 95% CI, 1.01-1.07), the presences of pulmonary fibrosis (HR, 2.43; 95% CI, 1.36-4.35), a lower FVC% (HR, 1.36; 95% CI, 1.10-1.68), and a history of smoking (HR, 2.01; 95% C1, 1.15-3.50) were independent predictors of shorter survival. After adjusting for mean age, presence of fibrosis, mean FVC%, mean diffusing capacity of the lung for carbon monoxide (%), and history of smoking, survival was longer for patients with an identified IA exposure than those with an unidentified IA exposure (median, 8.75 years vs 4.88 years; P = .047). Conclusions: Among patients with chronic HP, when adjusting for a number of potentially influential predictors, including the presence of fibrosis, the inability to identify an IA was independently associated with shortened survival.

    The links between Stn DBS and advanced Parkinson disease, and between GPi DBS and dystonia are nearly universally accepted by the neurologists and neurosurgeons. Nevertheless, in some conditions, targets such as the ventral thalamus and the Zona Incerta may be considered to optimize the results and avoid the side effects. Positive and negative aspects of current DBS treatments justify the research of new targets, new stimulation programs and new hardware. Since 1993, at the Istituto Nazionale Neurologico "Carlo Besta" in Milan, 580 deep brain electrodes were implanted in 332 patients. 276 patients were affected by movement disorders. The DBS targets included Stn, GPi, Voa, Vop, Vim, CM-pf, cZi, IC. The long-term follow-up is reported and related to the chosen target. DBS gave a new therapeutic option to patients affected by severe movement disorders, and in some cases resolved life-threatening pathological conditions that would otherwise result in the death of the patient, such as in status dystonicus, and post-stroke hemiballismus. Nevertheless, the potential occurrence of severe complications still limit a wider use of DBS. At today, the use of DBS in severe movement disorders is strongly positive even if further investigations and studies are needed to unveil potential new applications, and to refine the selection criteria for the actual indications and targets. The experience of different targets may be useful to guide and tailor the target choice to the individual clinical condition.

A heterogeneous group of patients, including 51 patients with pemphigus vulgaris, one with pemphigus vegetans, nine with pemphigus foliaceus, five with paraneoplastic pemphigus, four with epidermolysis bullosa acquisita, and one with both bullous pemphigoid and graft vs host disease was included in this survey. Overall the monoclonal antibody seems to be effective in that 69% of patients showed complete response, 25% of patients showed partial response, whereas 6% of patients showed progressive disease. Six deaths occurred in association with the treatment, with four of these deaths in patients with paraneoplastic pemphigus, a disease characteristically resistant to conventional medication and with a high mortality rate. Of note, 11 patients who received combined rituximab and intravenous immune globulin treatments had the best outcome: complete response without any serious side effects. Therefore further investigation on rituximab with controlled clinical trial is a worthy pursuit.Keywords: blistering diseases, skin, anti-CD20, pemphigus, epidermolysis bullosa acquisita

    The aim of this study is to evaluate the effectiveness and safety of percutaneously placed totally implantable venous-access ports (TIVAPs) of the forearm. Between January 2006 and October 2008, peripheral TIVAPs were implanted in 763 consecutive patients by ultrasound and fluoroscopic guidance. All catheters were implanted under local anesthesia and were tunneled subcutaneously. Indication, technical success, and complications were retrospectively analyzed according to Society of Interventional Radiology (SIR) criteria. Presence of antibiotic prophylaxis, periprocedurally administered drugs (e.g., sedation), and laboratory results at the time of implantation were analyzed. Maintenance during the service interval was evaluated. In total, 327,499 catheter-days were analyzed. Technical success rate was 99.3%. Reasons for initial failure of implantation were either unexpected thrombosis of the subclavian vein, expanding tumor mass of the mediastinum, or failure of peripheral venous access due to fragile vessels. Mean follow-up was 430 days. There were 115 complications observed (15.1%, 0.03 per 100 catheter-days), of which 33 (4.3%) were classified as early (within 30 days from implantation) and 82 (10.7%) as late. Catheter-related venous thrombosis was found in 65 (8.5%) of 763 (0.02 per 100 catheter-days) TIVAPs. Infections were observed in 41 (5.4%) of 763 (0.01 per 100 catheter-days) devices. Other complications observed included dislocation of the catheter tip (0.8%), occlusion (0.1%), or rupture (0.1%) of the port catheter. Dislocated catheters were corrected during a second interventional procedure. In conclusion, implantation of percutaneously placed peripheral TIVAPs shows a high technical success rate and low risk of early complications when ultrasound and fluoroscopic guidance are used. Late complications are observed three times as often as early complications.

    To determine the malignancy rate of bone lesions identified on FDG PET/CT in patients who have undergone CT-guided biopsy because of the suspicion of malignancy. This single-centre retrospective study spanned eight consecutive years and included all patients who underwent both FDG PET/CT and CT-guided bone biopsy because of the suspicion of malignancy. The positive predictive value (PPV) for malignancy was calculated, and different patient and imaging characteristics were compared between malignant and benign bone lesions. Of 102 included patients with bone lesions that all showed FDG uptake exceeding mediastinal uptake, bone biopsy showed a malignant lesion in 91 patients, yielding a PPV for malignancy of 89.2 % (95 % CI 81.7 - 93.9 %). In the 94 patients with bone lesions that showed FDG uptake exceeding liver uptake, bone biopsy showed a malignant lesion in 83 patients, yielding a PPV for malignancy of 88.3 % (95 % CI 80.1 - 93.5 %). Higher age, bone marrow replacement of the lesion seen on CT, expansion of the lesion seen on CT, and presence of multifocal lesions on FDG PET/CT were significantly more frequent in patients with malignant lesions than in those with benign bone lesions (P = 0.044, P = 0.009, P = 0.015, and P = 0.019, respectively). Furthermore, there was a trend towards a higher incidence of cortical destruction (P = 0.056) and surrounding soft tissue mass (P = 0.063) in patients with malignant bone lesions. The PPV for malignancy of suspicious bone lesions identified on FDG PET/CT is not sufficiently high to justify changes in patient management without histopathological confirmation. Nevertheless, ancillary patient and imaging characteristics may increase the likelihood of a malignant bone lesion. (orig.)

    To evaluate surgical results, speech, hearing, and craniofacial morphology after primary cleft repair performed from 1973 to 1979. During the years 1972 to 1985, all primary cleft surgeries were performed by 1 plastic surgeon, using Tennison lip closure combined with a periosteoplasty on the clefted alveolus at age 3 months. By mobilizing mucoperiosteal flaps, bony bridges were induced in the alveolar process in approximately 60% of the cases. All patients had the soft palate closed at age 24 months by a pushback technique. All children with complete unilateral clefts without soft tissue bands (unilateral cleft lip and palate) primary operated on 1973 to 1979 were included in the material, except 3 patients with a syndrome and 2 patients of foreign ethnicity. The material involved 30 consecutive patients with unilateral cleft lip and palate (20 boys and 10 girls; 16 left-sided and 14 right-sided clefts) who were operated on. Standardized records including photos, radiographs, lateral cephalograms, plaster model, and recording of speech and hearing were collected according to the treatment protocol at age 6, 15, and approximately 25 years. Evaluation included craniofacial descriptive cephalometric analysis, dentoalveolar morphology, dentofacial aesthetics, speech concerning articulation and nasality, and hearing status. Number of surgical interventions after primary surgery was recorded. Secondary revisions and candidates for orthognathic surgery are reported. Ten consecutive patients (case nos. 11-20) are demonstrated as clinical reports. : This longitudinal study shows how a multidisciplinary evaluation adequate for intercenter comparison can be performed when standardized procedures, registrations, and documentations are available.

    Purpose: Fatigue is an underevaluated cancer-related and treatment-related symptom. We analyzed fatigue in head and neck cancer patients undergoing radiotherapy (RT). Methods and Materials: A total of 117 patients were enrolled (mean age, 58 years). Radiation therapy (median dose, 66 Gy) was given with either exclusive or postoperative intent in 52 and 65 patients, respectively. Chemotherapy (CT) was added before and/or during RT in 61 patients. The patients completed a 20-item questionnaire (Multidimensional Fatigue Inventory [MFI-20]) before, during (weekly), and after RT. The impact of patient-, tumor-, and treatment-related factors on fatigue was evaluated with unifactorial and multifactorial tests. Results: Fatigue level increased during RT reaching a maximum at Week 6 and then slowly decreased. In multivariate stepwise regression analysis age (inversely related, p < 0.05), psychologic disorders (p < 0.005), and previous head-and-neck surgery (inversely related, p < 0.005) were correlated with higher pre-RT fatigue level. Pre-RT fatigue score (p < 0.0001), induction and/or concomitant CT (p = 0.035), need of cortisone during RT (p = 0.005), and thyroid disorders (p = 0.032) were correlated with higher during-RT fatigue level. Pre-RT fatigue score (p < 0.0001), induction and/or concomitant CT (p < 0.001), and need of cortisone during RT (p < 0.005) were correlated with higher post-RT fatigue level. No impact of gender, performance status, comorbidities other than psychologic and thyroid, tumor stage/site, RT intent, dose, volume, duration, or toxicity was observed. Conclusion: Fatigue affects all patients undergoing RT for head-and-neck cancer, reaches maximum score at the 6th week of RT, and slowly decreases thereafter. Age, thyroid dysfunction, psychologic disorders, pre-RT fatigue score, CT, and cortisone use are correlated with RT-related fatigue levels

    To analyze the complications of first 400 laparoscopic cholecystectomies (LC) for patients with symptomatic gall stone disease at a tertiary care hospital. Study Design: Quasi-experimental study. Place and Duration of Study: PNS Shifa Karachi and CMH Lahore, Pakistan from Nov 2009 to Jan 2013. Patients and Methods: A prospective analysis of complications occurring in first 400 consecutive laparoscopic cholecystectomies by a single consultant/unit at a tertiary care hospital was made. Out of total 421 patients presenting with symptomatic gall stone disease in a single unit, 21 cases that underwent open cholecystectomy were excluded from the study. Laparoscopic cholecystectomies were performed using three port and four port technique and data including age, sex, diagnosis, number of trocar placements, conversion to open surgery and its reasons, operative time, post-operative hospital stay and complications was collected on personal computer and analyzed using Statistical package for social sciences (SPSS) version 13. Results: Total 400 patients were included in study with median age of 44 years. Female to male ratio was 5.3: 1. Depending upon the preoperative diagnosis and laparoscopic findings, patients had diagnosis of Chronic cholecystitis / biliary colic 68.25%, acute cholecystitis 23.75%, empyema gall bladder 7.25%, gallstone pancreatitis 0.5% and mucocele gallbladder 0.25%. Median operating time was 30min. Median hospital stay was 1 days (range 1 -20 days). Conversion rate was 1.25%. Postoperative complications included bleeding 0.5%, biliaryperitonitis due to cystic duct leak 0.25%, biloma 0.25%, sub hepaticabscess 0.25%, subcutaneous fat necrosis right flank at drain site 0.25%, umbilical trocarsite infection 2%, keloid at umbilical port site 0.25% and incisional hernia at umbilicus 0.25%. There was one hospital death due to myocardial infarction on 2nd post-operative day. Conclusion: Laparoscopic Cholecystectomy is associated with some serious complications

    Posterior maxillary tilted implants are gaining prevalence as an alternative to sinus grafts supporting fixed maxillary restorations. This paper reports long-term results after loading using this technique. Consecutive patients presenting for either routine hygiene maintenance or unplanned emergency care who had received tilted implants as a sinus graft alternative to support fixed fully implant-supported restoration of an edentulous maxilla and were followed for a minimum of 10 years from initial implant placement were included in this evaluation. Forty-four patients were identified: 40 with bilateral tilted implants and 4 with one tilted and one axial posterior implant. Eight patients received one-piece fixed porcelain-to-gold screw-retained restorations, and thirty-six patients received a fully implant-supported patient-removable Marius Bridge. Seventy-nine out of 84 originally loaded posterior tilted implants survived a minimum of 10 years loading; one tilted implant was lost at 10 years. Eight additional posterior implants were placed for either these lost tilted posterior implants or as proactive supplemental support; one of these replacement tilted implants survived for at least 10 years and is included in the data. All patients have maintained continuous fixed function throughout the follow-up period. Forty-one out of 44 patients continue with the original restoration, 33 without modification or removal of the fixed restoration or implant-connecting bar. One porcelain-to-gold and seven Marius Bridges had framework modifications to accommodate additional implants; 3 Marius Bridge restorations were replaced with a newer generation. Within the limits of this retrospective study, the results show that continuous fixed function of fully implant-supported maxillary restorations using posterior tilted implants in terminal positions of support as a sinus graft alternative combined with axial anterior implants is possible over a prolonged period.

    Objective Physical healthcare has dominated the patient safety field; research in mental healthcare is not as extensive but findings from physical healthcare cannot be applied to mental healthcare because it delivers specialised care that faces unique challenges. Therefore, a clearer focus and recognition of patient safety in mental health as a distinct research area is still needed. The study aim is to identify future research priorities in the field of patient safety in mental health. Design Semistructured interviews were conducted with the experts to ascertain their views on research priorities in patient safety in mental health. A three-round online Delphi study was used to ascertain consensus on 117 research priority statements. Setting and participants Academic and service user experts from the USA, UK, Switzerland, Netherlands, Ireland, Denmark, Finland, Germany, Sweden, Australia, New Zealand and Singapore were included. Main outcome measures Agreement in research priorities on a five-point scale. Results Seventy-nine statements achieved consensus (>70%). Three out of the top six research priorities were patient driven; experts agreed that understanding the patient perspective on safety planning, on self-harm and on medication was important. Conclusions This is the first international Delphi study to identify research priorities in safety in the mental field as determined by expert academic and service user perspectives. A reasonable consensus was obtained from international perspectives on future research priorities in patient safety in mental health; however, the patient perspective on their mental healthcare is a priority. The research agenda for patient safety in mental health identified here should be informed by patient safety science more broadly and used to further establish this area as a priority in its own right. The safety of mental health patients must have parity with that of physical health patients to achieve this. PMID:29502096

    The prognostic value of CpG island methylator phenotype (CIMP) in colorectal cancer remains unsettled. We aimed to assess the prognostic value of this phenotype analyzing a total of 1126 tumor samples obtained from two Norwegian consecutive colorectal cancer series. CIMP status was determined by analyzing the 5-markers CAGNA1G, IGF2, NEUROG1, RUNX3 and SOCS1 by quantitative methylation specific PCR (qMSP). The effect of CIMP on time to recurrence (TTR) and overall survival (OS) were determined by uni- and multivariate analyses. Subgroup analyses were conducted according to MSI and BRAF mutation status, disease stage, and also age at time of diagnosis (CIMP positive tumors demonstrated significantly shorter TTR and worse OS compared to those with CIMP negative tumors (multivariate hazard ratio [95% CI] 1.86 [1.31-2.63] and 1.89 [1.34-2.65], respectively). In stratified analyses, CIMP tumors showed significantly worse outcome among patients with microsatellite stable (MSS, P CIMP is significantly associated with inferior outcome for colorectal cancer patients, and can stratify the poor prognostic patients with MSS BRAF mutated tumors. © 2017 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

    Full text: Following treatment with curative intent for non small cell lung cancer (NSCLC), assessment of disease status using conventional techniques is often difficult. We evaluated management impact and prognostic value of FDG PET in 63 consecutive patients undergoing restaging of NSCLC between 11/96 and 12/98. All patients were >6 months from primary treatment with curative intent. Salvage therapy with curative intent was being contemplated in 18 patients. Conventional imaging was abnormal 61/63 patients, two others had recurrent symptoms only. Compared to conventional restaging, 33% of patients were down-staged, and 35% were upstaged by PET. PET led to more aggressive treatment than planned in 7 patients (11%), a change from planned curative to palliative treatment in 8 patients (13%) and 17 patients (27%) thought to have recurrent disease had no further investigation or treatment after negative PET studies. Cox proportional hazards analysis indicated that a positive PET scan had a hazard ratio of 2.95 (95% CI 1.038.50, p = 0.012) compared to negative PET. Extent of active disease on PET was also prognostically significant with each incremental extent category (no disease, local recurrence, limited locoregional, extensive locoregional and systemic) having an estimated 60% increase in the rate of death (95% Cl 24% to 107%, p<0.0001). Stage of disease at initial diagnosis, primary treatment used and disease extent on conventional restaging were not predictive of survival. Thus, PET provided a high impact on management for NSCLC patients with suspected recurrence and more accurate prognostic stratification than conventional staging.

    It has been demonstrated that endovascular repair of arterial disease results in reduced perioperative morbidity and mortality compared to open surgical repair. The rates of complications and need for reinterventions, however, have been found to be higher than that in open repair. The purpose of this study was to identify the predictors of endograft complications and mortality in patients undergoing endovascular abdominal aortic aneurysm (AAA) repair; specifically, our aim was to identify a subset of patients with AAA whose risk of periprocedure mortality was so high that they should not be offered endovascular repair. We undertook a prospective review of patients with AAA receiving endovascular therapy at a single institution. Collected variables included age, gender, date of procedure, indication for procedure, size of aneurysm (where applicable), type of endograft used, presence of rupture, American Society of Anesthesiologists (ASA) class, major medical comorbidities, type of anesthesia (general, epidural, or local), length of intensive care unit (ICU) stay, and length of hospital stay. These factors were correlated with the study outcomes (overall mortality, graft complications, morbidity, and reintervention) using univariate and multivariate logistic regression. A total of 199 patients underwent endovascular AAA repair during the study period. The ICU stay, again, was significantly correlated with the primary outcomes (death and graft complications). In addition, length of hospital stay greater than 3 days, also emerged as a statistically significant predictor of graft complications in this subgroup (P = .024). Survival analysis for patients with AAA revealed that age over 85 years and ICU stay were predictive of decreased survival. Statistical analysis for other subgroups of patients (inflammatory AAA or dissection) was not performed due to the small numbers in these subgroups. Patients with AAA greater than 85 years of age are at a greater risk of mortality

    The aim of this retrospective study was to evaluate factors potentially influencing short- and long-term mortality in patients who had a non-traumatic lower limb amputation in a university hospital. A consecutive series of 93 amputations (16% toe/foot, 33% trans-tibial, 9% through knee and 42......% trans-femoral) were studied. Their mean age was 75.8 years; 21 (23%) were admitted from a nursing home and 87 (92%) were amputated due to a vascular disease and/or diabetes. Thirty days and 1-year mortality were 30 and 54%, respectively. Cox regression analysis demonstrated that the 30-day mortality...... was associated with older age (P = 0.01), and the number of co-morbidities (P = 0.04), when adjusted for gender, previous amputations, cause of and amputation level, and residential status. Thus, a patient with 4 or 5 co-morbidities (n = 20) was seven times more likely to die within 30 days, compared...

    Full Text Available Highly active antiretroviral therapy (HAART can cause side effects in HIV patients, as the metabolic syndrome. Early identification of risk for development of cardiovascular diseases using available reliable and practical methods is fundamental. On this basis, the aim of this study was to compare the effectiveness of anthropometric indicators to identify metabolic syndrome in HIV patients on HAART.It is a cross-sectional study. A number of 280 stable HIV patients were studied. It measured weight, height, waist circumference (WC, hip circumference (HP, thigh circumference (TC and calculated body mass index (BMI, body adiposity index (BAI, waist to hip ratio (WHR and waist to thigh ratio (WTR. There was also a performance of biochemical tests of lipid profile and fasting glucose. Systemic blood pressure was measured. The criteria proposed by the National Cholesterol Education Program III (NCEP-ATP III to metabolic syndrome classification was used. Individuals were divided in groups with or without metabolic alterations and their anthropometric indicators were compared. Receiver operating characteristic (ROC curves were designed for each anthropometric indicator using the metabolic syndrome classification to identify sensitivity and specificity.WC was a good tool to identify each metabolic disorder separately: total cholesterol (only females, p<0.05, triglycerides (only males, p<0.001, HDL cholesterol (p<0.05, LDL cholesterol (p<005 and fasting glycemic (p<005. WC also showed the best performance to identify metabolic syndrome in both genders (areas under the curve (AUCs: 0.79 and 0.76 for male and female, respectively, while BAI proved to be an inadequate indicator (AUCs: 0.63 and 0.67 for males and females, respectively, in this population.The central adiposity measure (WC had the best performance to identify metabolic syndrome, and it is a convenient, cheap and reliable tool that can be used in clinical practice routinely to prevent

    Accurate verification of patient identity during medication administration is an important component of medication administration practice. In medical and surgical inpatient settings, the use of identification aids, such as wristbands, is common. In many psychiatric inpatient units in Victoria, Australia, however, standardized identification aids are not used. The present paper outlines the findings of a qualitative research project that employed focus groups to examine mental health nurse and mental health consumer perspectives on the identification of patients during routine medication administration in psychiatric inpatient units. The study identified a range of different methods currently employed to verify patient identity, including technical methods, such as wristband and photographs, and interpersonal methods, such as patient recognition. There were marked similarities in the perspectives of mental health nurses and mental health consumers regarding their opinions and preferences. Technical aids were seen as important, but not as a replacement for the therapeutic nurse-patient encounter. © 2011 The Authors.

    Co-occurrence of Flt3ITD and TET2 mutations provoke an animal model of AML by epigenetic repression of Wnt pathway antagonists, including RUNX3, and by hyperexpression of ID1, encoding Wnt agonist. These affect HOXA over-expression and treatment resistance. A comparable epigenetic phenotype was identified among adult AML patients needing novel intervention. We chose combinations of targeted agents acting on distinct effectors, at the levels of both signal transduction and chromatin remodeling, in relapsed/refractory AML's, including Flt3ITD+ve, described with a signature of repressed tumor suppressor genes, involving Wnt antagonist RUNX3 , occurring along with ID1 and HOXA over-expressions. We tracked patient response to combination of Flt3/Raf inhibitor, Sorafenib, and Vorinostat, pan-histone deacetylase inhibitor, without or with added Bortezomib, in consecutive phase I trials. A striking association of rapid objective remissions (near-complete, complete responses) was noted to accompany induced early pharmacodynamic changes within patient blasts in situ, involving these effectors, significantly linking RUNX3 /Wnt antagonist de-repression (80%) and ID1 downregulation (85%), to a response, also preceded by profound HOXA9 repression. Response occurred in context of concurrent TET2 mutation/hypomorphy and Flt3ITD+ve mutation (83% of complete responses). Addition of Bortezomib to the combination was vital to attainment of complete response in Flt3ITD+ve cases exhibiting such Wnt pathway dysregulation.

    We sought to determine perioperative patterns of narcotic use and the prevalence of postoperative doctor shopping among patients with nephrolithiasis requiring operative management. We retrospectively reviewed the records of consecutive patients residing in Tennessee who required ureteroscopy with laser lithotripsy for nephrolithiasis at a single institution from January to December 2013. Using the Tennessee CSMD (Controlled Substances Medication Database) patients were categorized by the number of postoperative narcotic providers. Doctor shopping behavior was identified as any patient seeking more than 1 narcotic provider within 3 months of surgery. Demographic and clinical characteristics associated with doctor shopping behavior were identified. During the study period 200 eligible patients underwent ureteroscopy with laser lithotripsy for nephrolithiasis, of whom 48 (24%) were prescribed narcotics by more than 1 provider after surgery. Compared to those receiving narcotics from a single provider, patients with multiple narcotic providers were younger (48.1 vs 54.2 years, p shopping is common among patients with nephrolithiasis who require operative management. Urologists should be aware of available registry data to decrease the likelihood of redundant narcotic prescribing. Copyright © 2016 American Urological Association Education and Research, Inc.

    Stroke leads to high mortality and morbidity but often there is a conflict between need for palliative care and avoidance of 'therapeutic nihilism'. We aimed to elicit the palliative care needs of stroke patients at the end of their lives in our unit with a low overall mortality rate (1 month: 8.8 %, inpatient: 12.9 %). We identified consecutive stroke patients who died over 2 years. Their clinical records were used for data collection. Of 54 deaths, 33 (61.1 %) were females, mean (SD) age at death was 79.3 ± 12.9 years. 41 (75.9 %) died after first stroke, 9 (16.7 %) were inpatient strokes, 7 (13.0 %) thrombolysed and 7 (13.0 %) had strokes as treatment complication. There were clear statements recorded in 26 (48.1 %) that patients were dying and death was thought to be due primarily to extent of brain injury in 24 (44.4 %). Palliative needs identified included dyspnoea 21 (38.9 %), pain 17 (31.5 %), respiratory secretions 17 (31.5 %), agitation 14 (25.9 %) and psychological distress 1 (1.9 %). Symptoms were due to premorbid diseases in 6 (11.1 %). Palliative care expertise were sought in 13 (24.1 %) and continuous subcutaneous infusion was used in 18 (33.3 %) to control symptoms. 4 (7.4 %) subjects underwent cardiac arrest calls and 9 (16.7 %) deaths occurred in ICU/HDU. The median Stroke-Death interval was 20 days (range 0-389). Do Not Attempt Resuscitation (DNAR) orders were in place in 86.8 % of patients. The median DNAR-Death interval was 7 days (range 0-311) with 7-day DNAR-Death rate of 53.2 % and 30-day of 78.7 % of the total deaths. Dyspnoea, pain and respiratory secretions were identified as the main palliative care needs.

    The primary aim of this study was to determine whether orthopaedic trauma patients receive appropriate antibiotic prophylaxis keeping in view the results of their MRSA screening. The secondary aim was to analyse the risk of developing MRSA surgical site infection with and without appropriate antibiotic prophylaxis in those colonized with MRSA. We reviewed 400 consecutive orthopaedic trauma patient episodes. Preoperative MRSA screening results, operative procedures, prophylactic antibiotics and postoperative course were explored. In addition to these consecutive patients, the hospital MRSA database over the previous 5 years identified 27 MRSA colonized acute trauma patients requiring surgery. Of the 400 consecutive patient episodes, 395(98.7%) had MRSA screening performed on admission. However, in 236 (59.0%) cases, the results were not available before the surgery. Seven patient episodes (1.8%) had positive MRSA colonization. Analysis of 27 MRSA colonized patients revealed that 20(74%) patients did not have the screening results available before the surgery. Only 5(18.5%) received Teicoplanin and 22(81.4%) received cefuroxime for antibiotic prophylaxis before their surgery. Of those receiving cefuroxime, five (22.73%) patients developed postoperative MRSA surgical site infection (SSI) but none of those (0%) receiving Teicoplanin had MRSA SSI. The absolute risk reduction for SSI with Teicoplanin as antibiotic prophylaxis was 22.73% (CI=5.22%-40.24%) and NNT (Number Needed to Treat) was 5 (CI=2.5-19.2) CONCLUSION: Lack of available screening results before the surgery may lead to inadequate antibiotic prophylaxis increasing the risk of MRSA surgical site infection. Glycopeptide (e.g.Teicoplanin) prophylaxis should be considered when there is history of MRSA colonization or MRSA screening results are not available before the surgery. Copyright © 2017.

    The aim of the present investigation was to elucidate in a large consecutive patient cohort whether the level of training has an effect on the number of microemboli detected by diffusion-weighted imaging (DWI) and which additional risk factors can be identified. A total of 107 consecutive patients in whom a diagnostic cerebral angiography had been performed were prospectively investigated with DWI; 51 angiographies were performed by experienced neuroradiologists, 56 by neuroradiologists in training. In 12 patients (11.1%), a total of 17 new lesions without any clinically overt neurological symptoms were identified. Of these, 12 patients, 11 (91.7%) with 16 lesions were investigated by junior neuroradiologists. In 11 of 12 patients with DWI abnormalities (91.7%), risk factors could be identified (atherosclerotic vessel wall disease, vasculitis, hypercoagulable states). Experienced neuroradiologists performed 21 of 48 angiographies (43.8%) on patients with the above-mentioned risk factors, whereas junior neuroradiologists performed 27 angiographies in this subgroup (46.2%). The rate of diffusion abnormalities in patients with risk factors was 11/48 (22.9%) - considerably higher than in patients without risk factors (1/59; 1.7%). The level of experience and the nature of the underlying disease are predictors of the occurrence of cerebral ischemic events following neuroangiography. Alternative diagnostic modalities should be employed in patients who are investigated for diseases with the highest risk of angiographic complications (i.e., vasculitis, and arteriosclerotic vessel wall disease). If diagnostic angiography remains necessary in these patients, the highest level of practitioner training is necessary to ensure good patient outcome. (orig.)

    Chronic non-healing wounds are a major human and economic burden. Obstructive sleep apnea (OSA) is prevalent in patients with obesity, diabetes, aging, and cardiovascular disease, all of which are risk factors for chronic wounds. We hypothesized that OSA would have more prevalence in patients of a wound center than the general middle-aged population. Consecutive patients of the Ohio State University Comprehensive Wound Center (CWC) were surveyed with the Berlin and Epworth questionnaires. In the second stage of the protocol, 50 consecutive unselected CWC patients with lower extremity wounds underwent home sleep studies. In 249 patients of the CWC who underwent the survey study, OSA had been previously diagnosed in only 22%. The prevalence of high-risk status based on questionnaires for OSA was 46% (95% CI 40%, 52%). In the 50 patients who underwent home sleep studies, and using an apnea hypopnea index of 15 events per hour, the prevalence of OSA was 57% (95% CI 42%, 71%). There was no difference between the Berlin questionnaire score and weight between patients with OSA and those without. The prevalence of OSA in patients with chronic wounds exceeds the estimated prevalence of OSA in the general middle aged population. This study identifies a previously unrecognized population with high risk for OSA. Commonly used questionnaires were not sufficiently sensitive for the detection of high risk status for OSA in this patient population.

    The purpose of the study was to evaluate the prostate serum antigen (PSA) response, local control, progression-free survival (PFS), and toxicity of stereotactic body radiotherapy (SBRT) for lymph node (LN) oligorecurrent prostate cancer. Between May 2012 and October 2015, 124 lesions were treated in 94 patients with a median dose of 24 Gy in 3 fractions. Seventy patients were treated for a single lesion and 25 for > 1 lesion. In 34 patients androgen deprivation (AD) was combined with SBRT. We evaluated biochemical response according to PSA level every 3 months after SBRT: a 3-month PSA decrease from pre-SBRT PSA of more than 10% identified responder patients. In case of PSA level increase, imaging was performed to evaluate clinical progression. Toxicity was assessed every 6 to 9 months after SBRT. Median follow-up was 18.5 months. In 13 patients (14%) Grade 1 to 2 toxicity was reported without any Grade 3 to 4 toxicity. Biochemical response, stabilization, and progression were observed in 64 (68%), 10 (11%), and 20 (21%) of 94 evaluable patients. Clinical progression was observed in 31 patients (33%) after a median time of 8.1 months. In-field progression occurred in 12 lesions (9.7%). Two-year local control and PFS rates were 84% and 30%, respectively. Age older than 75 years correlated with better biochemical response rate. Age older than 75 years, concomitant AD administered up to 12 months, and pelvic LN involvement correlated with longer PFS. SBRT is safe and offers good in-field control. At 2 years after SBRT, 1 of 3 patients is progression-free. Further investigation is warranted to identify patients who benefit most from SBRT and to define the optimal combination with AD.

    Full Text Available Abstract Background Ocular surface squamous neoplasia (OSSN is a rare cancer that has increased in incidence with the HIV pandemic in Africa. The underlying cause of this cancer in HIV-infected patients from Botswana is not well defined. Results Tissues were obtained from 28 OSSN and 8 pterygia patients. The tissues analyzed from OSSN patients were 83% positive for EBV, 75% were HPV positive, 70% were KSHV positive, 75% were HSV-1/2 positive, and 61% were CMV positive by PCR. Tissues from pterygium patients were 88% positive for EBV, 75% were HPV positive, 50% were KSHV positive, and 60% were CMV positive. None of the patients were JC or BK positive. In situ hybridization and immunohistochemistry analyses further identified HPV, EBV, and KSHV in a subset of the tissue samples. Conclusion We identified the known oncogenic viruses HPV, KSHV, and EBV in OSSN and pterygia tissues. The presence of these tumor viruses in OSSN suggests that they may contribute to the development of this malignancy in the HIV population. Further studies are necessary to characterize the molecular mechanisms associated with viral antigens and their potential role in the development of OSSN.

    Purpose: To determine the feasibility of high dose radiotherapy and to evaluate its role in the management of extrahepatic bile duct (EHBD) cancer. Methods and Materials: Between 1983 and 1991, 145 consecutive patients with EHBD cancer were treated by low dose rate intraluminal 192 Ir irradiation (ILRT) either alone or in combination with external beam radiotherapy (EBRT). Among the primarily irradiated, 77 patients unsuitable for surgical resection, 54 were enrolled in radical radiotherapy, and 23 received palliative radiotherapy. Fifty-nine received postoperative radiotherapy, and the remaining 9 preoperative radiotherapy. The mean radiation dose was 67.8 Gy, ranging from 10 to 135 Gy. Intraluminal 192 Ir irradiation was indicated in 103 patients, and 85 of them were combined with EBRT. Expandable metallic biliary endoprosthesis (EMBE) was used in 32 primarily irradiated patients (31 radical and 1 palliative radiotherapy) after the completion of radiotherapy. Results: The 1-, 3-, and 5-year actuarial survival rates for all 145 patients were 55%, 18%, and 10%, for the 54 patients treated by radical radiotherapy (mean 83.1 Gy), 56%, 13%, and 6% [median survival time (MST) 12.4 months], and for the 59 patients receiving postoperative radiotherapy (mean 61.6 Gy), 73%, 31%, and 18% (MST 21.5 months), respectively. Expandable metallic biliary endoprosthesis was useful for the early establishment of an internal bile passage in radically irradiated patients and MST of 14.9 months in these 31 patients was significantly longer than that of 9.3 months in the remaining 23 patients without EMBE placement (p < 0.05). Eighteen patients whose surgical margins were positive in the hepatic side bile duct(s) showed significantly better survival compared with 15 patients whose surgical margins were positive in the adjacent structure(s) (44% vs. 0% survival at 3 years, p < 0.001). No survival benefit was obtained in patients given palliative or preoperative radiotherapy

    Abdominal hysterectomy is one of the most common major operations in gynaecology. However, it is associated with considerable morbidity and relatively slow recovery. The superiority of hysterectomy by the vaginal route is not denied. It is associated with a significant fewer complications than abdominal hysterectomy. This study was done with the aim to determine what proportion of hysterectomies performed via abdominal route could have been performed vaginally or with laparoscopic assistance. Methods: Case notes of one hundred consecutive patients who had an abdominal hysterectomy were obtained from the records department. Out of 100 cases only 85 case notes were made available for analysis. Results: A total of 74 cases for benign disorder were studied; 50% of the cases were over the age of 40 years and 82% of the patients were multiparous. The uterine size was less than 12 weeks in 67 cases. About 44.6% of cases were found to have menorrhagia without any organic pathology. For the majority of cases it was not apparent from the cases notes as to the degree of uterine descent. Three patients required blood transfusion in the preoperative group and 7 cases in the postoperative group. Primary haemorrhage was noted in 3 cases. Three patients needed readmission for secondary haemorrhage due to vault hematoma formation and in one case a hematoma of rectus sheath was noted which needed drainage. Paralytic ileus was noted in 2 cases and one case had intestinal obstruction. Most of the patients were allowed home within 7 days. One patient stayed for 17 days due to intestinal obstruction requiring laparotomies and gut resection. Majority of the cases were done by the consultants. Conclusion: By considering the specific guidelines for vaginal hysterectomy, every patient who need hysterectomy should be assessed for vaginal hysterectomy, provided there is no contraindication for it. Preoperative assessment under anaesthesia should be an integral part of management of a patient

    To identify and potentially modify the risk of pulmonary complications in a group of older patients with hip fracture, the authors obtained speech and language pathology consultations for these patients. Then they performed a retrospective chart review of all patients 65 years and older who were admitted to their institution between June 2011 and July 2013 with acute hip fracture, were treated surgically, and had a speech and language pathology evaluation in the immediate perioperative period. The authors identified 52 patients who met the study criteria. According to the American Society of Anesthesiologists (ASA) classification system, at the time of surgery, 1 patient (2%) was classified as ASA I, 12 patients (23%) were ASA II, 26 (50%) were ASA III, and 12 (23%) were ASA IV. Based on a speech and language pathology evaluation, 22 patients (42%) were diagnosed with dysphagia. Statistical analysis showed that ASA III status and ASA IV status were meaningful predictors of dysphagia and that dysphagia itself was a strong risk factor for pulmonary aspiration, pneumonia, and aspiration pneumonitis. Evaluation by a speech and language pathologist, particularly of patients classified as ASA III or ASA IV, may be an efficient means of averting pulmonary morbidity that is common in older patients with hip fracture.

    Full Text Available Infections caused by emerging Cryptococcus non-neoformans species are being reported with increasingly frequency. Here, we present a case of fungaemia by Cryptococcus laurentii in a woman receiving aggressive immunosuppressive therapy for cervical neoplasia. Three venous blood samples were aseptically collected on consecutive days and C. laurentii was isolated and identified through phenotypic and molecular methods. After central venous catheter removal and appropriate antifungal therapy, the patient showed significant improvement and blood culture became negative. Thus, patients following immunosuppressive therapies and using invasive medical devices are at risk of C. laurentii blood infections.

  12. A target based approach identifies genomic predictors of breast cancer patient response to chemotherapy

    2012-05-01

    Full Text Available Abstract Background The efficacy of chemotherapy regimens in breast cancer patients is variable and unpredictable. Whether individual patients either achieve long-term remission or suffer recurrence after therapy may be dictated by intrinsic properties of their breast tumors including genetic lesions and consequent aberrant transcriptional programs. Global gene expression profiling provides a powerful tool to identify such tumor-intrinsic transcriptional programs, whose analyses provide insight into the underlying biology of individual patient tumors. For example, multi-gene expression signatures have been identified that can predict the likelihood of disease reccurrence, and thus guide patient prognosis. Whereas such prognostic signatures are being introduced in the clinical setting, similar signatures that predict sensitivity or resistance to chemotherapy are not currently clinically available. Methods We used gene expression profiling to identify genes that were co-expressed with genes whose transcripts encode the protein targets of commonly used chemotherapeutic agents. Results Here, we present target based expression indices that predict breast tumor response to anthracycline and taxane based chemotherapy. Indeed, these signatures were independently predictive of chemotherapy response after adjusting for standard clinic-pathological variables such as age, grade, and estrogen receptor status in a cohort of 488 breast cancer patients treated with adriamycin and taxotere/taxol. Conclusions Importantly, our findings suggest the practicality of developing target based indices that predict response to therapeutics, as well as highlight the possibility of using gene signatures to guide the use of chemotherapy during treatment of breast cancer patients.

    From January 1998 to December 2002, endovascular treatment (EVT) was used as first intention in all patients with ruptured aneurysms. The objective of this study was to analyze the results of this therapeutic strategy. Among 401 patients admitted with a subarachnoid hemorrhage (SAH), 73 (18%) had a nonaneurysmal perimesencephalic SAH, 28 were not explored by angiography due to very poor clinical status, and 28 with aneurysmal SAH were not treated due to poor clinical status. Thus, of the 300 patients with a proven aneurysmal SAH, 272 (83%) were treated. EVT was attempted in 230 patients and was successful in 222 (82%), and clipping was performed in 50 (18%). Finally, EVT was successful in 234 aneurysms (96.7%) in 222 patients out of 242 aneurysms in 230 patients (some of the patients were treated for more than one aneurysm in the same procedure). EVT-related morbidity occurred in ten patients (4.5%) and mortality in eight (3.6%). Rate of dependency or death (modified Rankin scale 3-5) was 24.5% at 26 months. Initially, complete aneurysm occlusion was obtained in 81%, a dog ear in 3.4%, a neck remnant in 8% and incomplete occlusion in 8.1% of the patients. At follow-up (mean 26 months), the occlusion rate remained stable at 75%. This consecutive prospective series shows that EVT can be performed routinely as first-intention treatment in most aneurysmal SAH. Using this therapeutic strategy, EVT was performed in 82% of patients with long-term clinical results similar to those of the ISAT study. (orig.)

    This study explored whether working memory and sustained attention influence cognitive lock-up, which is a delay in the response to consecutive automation failures. Previous research has demonstrated that the information that automation provides about failures and the time pressure that is associated with a task influence cognitive lock-up. Previous research has also demonstrated considerable variability in cognitive lock-up between participants. This is why individual differences might influence cognitive lock-up. The present study tested whether working memory-including flexibility in executive functioning-and sustained attention might be crucial in this regard. Eighty-five participants were asked to monitor automated aircraft functions. The experimental manipulation consisted of whether or not an initial automation failure was followed by a consecutive failure. Reaction times to the failures were recorded. Participants' working-memory and sustained-attention abilities were assessed with standardized tests. As expected, participants' reactions to consecutive failures were slower than their reactions to initial failures. In addition, working-memory and sustained-attention abilities enhanced the speed with which participants reacted to failures, more so with regard to consecutive than to initial failures. The findings highlight that operators with better working memory and sustained attention have small advantages when initial failures occur, but their advantages increase across consecutive failures. The results stress the need to consider personnel selection strategies to mitigate cognitive lock-up in general and training procedures to enhance the performance of low ability operators. © 2016, Human Factors and Ergonomics Society.

    Performance improvements after caffeine (CAF) ingestion are well documented when using a 1-d protocol. In numerous competitions such as the Tour de France, Tour de Ski, world championships, and National College Athletic Association championships, athletes compete for several days in a row. To date, no studies have investigated the effects of CAF when competing for consecutive days in a row. This study aimed to investigate the effects of placebo (PLA) and two different CAF doses (3 and 4.5 mg·kg body mass) on performance in a 10-min all-out, cross-country, double poling ergometer test (C-PT) 2 d in a row. Eight highly trained male cross-country skiers (V˙O2max-run, 78.5 ± 1.6 mL·kg·min) participated in the study, which was a randomized, double-blind, PLA-controlled, crossover design. Performance was assessed as distance covered during a 10-min all-out C-PT. Oral ingestion of CAF or PLA was consumed 75 min before the all-out C-PT. Poling distance was improved after CAF ingestions compared with that after PLA on both days. The improvements on day 1 were 4.0% (90% confidence limits, ±3.3) and 4.0% ± 2.9% for both CAF doses, respectively (P performance was associated with increased HR, adrenaline concentration, blood lactate concentration, and V˙O2 consumption after CAF ingestion. Furthermore, performance was elevated despite higher creatine kinase concentration and muscular pain at arrival on day 2 for both CAF doses. Both CAF doses improved performance in the 10-min all-out C-PT compared with PLA over two consecutive days. Therefore, CAF seems useful for athletes competing over consecutive days despite higher muscle damage occurring after enhanced performance on the first day.

Results In group A, mean age was 51 years of age compared to 68 years in group B. An iterative procedure was performed in 13% of patients in group B. Thirty days mortality was 3% in group A and 1% in group B despite greater operative risk factors, with more redo, and lower ejection fraction in group B. Several factors contributed to the low morbidity-mortality in group B, namely: preoperative erythropoietin to attain a minimal hemoglobin value of 14 g/dl, warm blood cardioplegia, the implementation of the Cornell University protocol and fast track extubation. Conclusions Cardiac surgery without transfusion in high-risk patients such as Jehovah Witnesses can be carried out with results equivalent to those of low risk patients. Recent advances in surgical techniques and blood conservation protocols are main contributing factors.

    Our primary aim was to determine the rate of overseas travel in immunocompromised individuals attending appropriate clinics at an Australian tertiary care hospital. We also aimed to characterise health-seeking behaviour prior to travel and investigated sources of pre-travel advice, compared travel patterns and activities between three specific immunosuppressed groups, and examined pre-immunosuppression patient serology. We implemented a cross-sectional survey of patients between February and August 2012. This survey was implemented among three outpatient populations at Monash Medical Centre, an Australian tertiary care hospital. We recruited 254 immunosuppressed adults from three patient populations: human immunodeficiency virus-positive individuals, renal transplant patients and rheumatology patients requiring immunosuppressive therapy. No clinical intervention was performed. In the 10 years preceding the survey, 153 (60.2%) participants reported international travel. Of these, 105 (68.6%) were immunosuppressed at the time of travel. These patients were 47.6% male and 60% Australian born. Forty per cent were visiting friends and relatives as part of their travel. Fifty-four per cent of those immunocompromised at the time of travel were going to high-risk destinations. Pathology files indicated that serological screening was frequently not performed prior to immunosuppression in the renal transplant and rheumatology groups. Immunocompromised patients often travel to high-risk destinations with limited or inadequate pre-travel preparations. Doctors caring for the immunocompromised should be aware of travel risks, suitable vaccination protocols and when to refer to specialist travel clinics. © 2015 Royal Australasian College of Physicians.

    Sentinel node biopsy often results in the identification and removal of multiple nodes as sentinel nodes, although most of these nodes could be non-sentinel nodes. This study investigated whether computed tomography-lymphography (CT-LG) can distinguish sentinel nodes from non-sentinel nodes and whether sentinel nodes identified by CT-LG can accurately stage the axilla in patients with breast cancer. This study included 184 patients with breast cancer and clinically negative nodes. Contrast agent was injected interstitially. The location of sentinel nodes was marked on the skin surface using a CT laser light navigator system. Lymph nodes located just under the marks were first removed as sentinel nodes. Then, all dyed nodes or all hot nodes were removed. The mean number of sentinel nodes identified by CT-LG was significantly lower than that of dyed and/or hot nodes removed (1.1 vs 1.8, p <0.0001). Twenty-three (12.5%) patients had ≥2 sentinel nodes identified by CT-LG removed, whereas 94 (51.1%) of patients had ≥2 dyed and/or hot nodes removed (p <0.0001). Pathological evaluation demonstrated that 47 (25.5%) of 184 patients had metastasis to at least one node. All 47 patients demonstrated metastases to at least one of the sentinel nodes identified by CT-LG. CT-LG can distinguish sentinel nodes from non-sentinel nodes, and sentinel nodes identified by CT-LG can accurately stage the axilla in patients with breast cancer. Successful identification of sentinel nodes using CT-LG may facilitate image-based diagnosis of metastasis, possibly leading to the omission of sentinel node biopsy

    Minimally invasive techniques have revolutionized the field of general surgery over the few last decades. Despite its advantages, in complex procedures such as rectal surgery, laparoscopy has not achieved a high penetration rate because of its steep learning curve, its relatively high conversion rate and technical challenges. The aim of this study was to present a single center experience with robotic surgery for rectal cancer focusing mainly on early and mid-term postoperative outcome. A series of 100 consecutive patients who underwent robotic rectal surgery between January 2008 and June 2012 was analyzed retrospectively in terms of demographics, pathological data, surgical and oncological outcomes. Seventy-seven patients underwent robotic sphincter-saving resection, and 23 patients underwent robotic abdominoperineal resection. There were 4 conversions. The median operative time for sphincter-saving procedures was 180 min. The median time for robotic abdominoperineal resection was 160 min. The median distal resection margin of the operative specimen was 3 cm. The median number of retrieved lymph nodes was 14. The median hospital stay was 10 days. In-hospital mortality was nil. The overall morbidity was 30%. Four patients presented transitory postoperative urinary dysfunction. Severe erectile dysfunction was reported by 3 patients. The median length of follow-up was 24 months. The 3-year overall survival rate was 90%. Robotic surgery is advantageous for both surgeons (in that it facilitates dissection in a narrow pelvis) and patients (in that it affords a very good quality of life via the preservation of sexual and urinary function in the vast majority of patients and it has low morbidity and good midterm oncological outcomes). In rectal cancer surgery, the robotic approach is a promising alternative and is expected to overcome the low penetration rate of laparoscopy in this field. Celsius.

    Full Text Available Background: Designated psychiatric facilities are responsible for the care, treatment and reintegration of State patients. The necessary long-term care places a considerable strain on health-care resources. Resource use should be optimised while managing the risks that patients pose to themselves and the community. Identifying unique factors associated with earlier discharge may decrease the length of stay. Factors associated with protracted inpatient care without discharge could identify patients who require early and urgent intervention. Aim: We identify socio-economic, demographic, psychiatric and charge-related factors associated with the discharge of male State patients. Methods: We reviewed the files of discharged and admitted forensic State patients at Weskoppies Psychiatric Hospital. Data were captured in an electronic recording sheet. The association between factors and the outcome measure (discharged vs. admitted was determined using chi-squared tests and Fischer’s exact tests. Results: Discharged State patients were associated with being a primary caregiver (p = 0.031 having good insight into illness (p = 0.025 or offence (p = 0.005 and having had multiple successful leaves of absences. A lack of substance abuse during admission (p = 0.027, an absence of a diagnosis of substance use disorder (p = 0.013 and the absence of verbal and physical aggression (p = 0.002 and p = 0.016 were associated with being discharged. Prolonged total length of stay (9–12 years, p = 0.031 and prolonged length of stay in open wards (6–9 years, p = 0.000 were associated with being discharged. A history of previous offences (p = 0.022, a diagnosis of substance use disorder (p = 0.023, recent substance abuse (p = 0.018 and a history of physical aggression since admission (p = 0.017 were associated with continued admission. Conclusion: Discharge of State patients is associated with an absence of substance abuse, lack of aggression

    Skull opening in occipital and suboccipital regions might be associated with risk of damage to the transverse venous sinus and the confluence of sinuses. We analyze the value of magnetic resonance (MR) imaging in localizing the venous sinuses in relation to the superior muscle insertion line (MIL) on the occipital bone. We retrospectively analyzed head MR images of 100 consecutive patients imaged for any reason from 1 January 2013. All MR images were interpreted by a radiologist (R.K.). The superior MIL was identified at the midline and on both midpupillar lines, which represent the most frequent sites of skin incision and craniotomy (median and lateral suboccipital craniotomy, respectively). Patients comprised 56 women (56%) and 44 men (44%). Their mean age was 54 (range 18-84) years. The muscles of the posterior skull were readily visible and clearly identified in both T1 and T2 images of all patients. Identification of the insertion zone and its relation to the venous structures was most readily made in the sagittal plane. We found that the upper muscle insertion line on occipital bone corresponds to the underlying venous sinus and can be used as a reliable anatomic landmark. We identified it in 100% of preoperative MR images of heads with an intact occiput. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Administrative data is often used to identify patients with chronic obstructive pulmonary disease (COPD, yet the validity of this approach is unclear. We sought to develop a predictive model utilizing administrative data to accurately identify patients with COPD. Methods Sequential logistic regression models were constructed using 9573 patients with postbronchodilator spirometry at two Veterans Affairs medical centers (2003-2007. COPD was defined as: 1 FEV1/FVC Results 4564 of 9573 patients (47.7% had an FEV1/FVC Conclusion Commonly used definitions of COPD in observational studies misclassify the majority of patients as having COPD. Using multiple diagnostic codes in combination with pharmacy data improves the ability to accurately identify patients with COPD.

    Background: Vertebral anomalies may help differentiate Alagille syndrome from other causes of chronic cholestasis. We suspect significant under-reporting of vertebral anomalies in children with Alagille syndrome. Objective: To compare the vertebral anomalies in Alagille syndrome with those in patients with chronic cholestasis due to other causes. The accuracy of original radiographic reporting was evaluated. Materials and methods: Spinal radiographs of 50 patients with Alagille syndrome and 31 non-Alagille syndrome cholestatic patients were evaluated retrospectively by four trained radiologists. The number, site and type of vertebral anomaly were noted. The consensus evaluation was then compared to the original report. Results: Vertebral anomalies were found in 66% of patients with Alagille syndrome and 9.7% of cholestatic control subjects (P<0.0005). In the patients with Alagille syndrome, incomplete fusion of the anterior arch, most frequently at the D6-9 level, accounted for 123 of 126 anomalies. Multiple vertebral anomalies occurred in 48% of patients with Alagille syndrome (mean 2.5 anomalies). Vertebral anomalies were misreported in 54% of cases of Alagille syndrome. Conclusions: Vertebral anomalies are significantly more common in Alagille syndrome than in chronic cholestasis of other causes and are frequently overlooked. Reporting should be undertaken by a radiologist familiar with the appearance and location of these vertebral anomalies. (orig.)

    We assessed the molecular characteristics and the frequency of mutations in mismatch-repair genes among Bedouin patients with colorectal cancer (CRC) in Israel. Bedouin patients with a diagnosis of CRC at a major hospital in the southern part of Israel were deemed eligible for this study. The primary screening method was immunohistochemical staining for mismatch-repair proteins (MLH1, MSH2, MSH6, and PMS2). For subjects with abnormal immunohistochemical staining, we performed microsatellite instability (MSI) analyses, and for tumors with a loss of MLH1 expression we also performed BRAF testing. In MSI high cases we searched further for germline mutations. Of the 24 patients enrolled, four subjects (16.7%) had MSI high tumors: one subject was found to harbor a biallelic PMS2 mutation, one subject had Lynch syndrome (LS) with MSH6 mutation and two subjects had a loss of MLH1/PMS2 proteins/BRAF wild type /normal MLH1 sequence. Ten patients (41.7%) were younger than 50 at the time of diagnosis and none had first degree relatives with CRC. In conclusion, in this cohort of 24 consecutive Arab Bedouins with CRC, one patient was found to harbor a constitutional mismatch repair deficiency, one patient had LS with MSH6 mutation, and two patients had unresolved loss of MLH1/PMS2 proteins/BRAF wild type phenotype.

    The aim of this study was to determine the patient characteristics that predict 1-year mortality after a hip fracture (HF). All patients admitted consecutively with fragility HF during 1 year in a co-managed orthogeriatric unit of a university hospital (FONDA cohort) were assesed. Baseline and admission demographic, clinical, functional, analytical and body-composition variables were collected in the first 72 h after admission. A protocol designed to minimize the consequences of the HF was applied. One year after the fracture patients or their carers were contacted by telephone to ascertain their vital status. A total of 509 patients with a mean age of 85.6 years were included. One-year mortality was 23.2%. The final multivariate model included 8 independent mortality risk factors: age >85 years, baseline functional impairment in basic activities of daily living, low body mass index, cognitive impairment, heart disease, low hand-grip strength, anaemia at admission, and secondary hyperparathyroidism associated with vitamin D deficiency. The association of several of these factors greatly increased mortality risk, with an OR (95% confidence interval [CI]) of 5.372 (3.227-8.806) in patients with 4 to 5 factors, and an OR (95% CI) of 11.097 (6.432-19.144) in those with 6 or more factors. In addition to previously known factors (such as age, impairment in basic activities of daily living, cognitive impairment, malnutrition and anaemia at admission), other factors, such as muscle strength and hyperparathyroidism associated with vitamin D deficiency, are associated with greater 1-year mortality after a HF.

    2009-01-01

    The aim of the present study was to identify the game-related statistics that discriminated basketball winning and losing teams in each of the three consecutive games played in a condensed tournament format. The data were obtained from the Spanish Basketball Federation and included game-related statistics from the Under-20 league (2005-2006 and 2006-2007 seasons). A total of 223 games were analyzed with the following game-related statistics: two and three-point field goal (made and missed), free-throws (made and missed), offensive and defensive rebounds, assists, steals, turnovers, blocks (made and received), fouls committed, ball possessions and offensive rating. Results showed that winning teams in this competition had better values in all game-related statistics, with the exception of three point field goals made, free-throws missed and turnovers (p ≥ 0.05). The main effect of game number was only identified in turnovers, with a statistical significant decrease between the second and third game. No interaction was found in the analysed variables. A discriminant analysis allowed identifying the two-point field goals made, the defensive rebounds and the assists as discriminators between winning and losing teams in all three games. Additionally to these, only the three-point field goals made contributed to discriminate teams in game three, suggesting a moderate effect of fatigue. Coaches may benefit from being aware of this variation in game determinant related statistics and, also, from using offensive and defensive strategies in the third game, allowing to explore or hide the three point field-goals performance. Key points Overall team performances along the three consecutive games were very similar, not confirming an accumulated fatigue effect. The results from the three-point field goals in the third game suggested that winning teams were able to shoot better from longer distances and this could be the result of exhibiting higher conditioning status and

    Patients undergoing a bone marrow stem cell transplant (BMT) face various risk factors. Analyzing data from past transplants could enhance the understanding of the factors influencing success. Records up to 120 measurements per transplant procedure from 1751 patients undergoing BMT were collected (Shariati Hospital). Collaborative filtering techniques allowed the processing of highly sparse records with 22.3% missing values. Ten-fold cross-validation was used to evaluate the performance of various classification algorithms trained on predicting the survival status. Modest accuracy levels were obtained in predicting the survival status (AUC = 0.69). More importantly, however, operations that had the highest chances of success were shown to be identifiable with high accuracy, e.g., 92% or 97% when identifying 74 or 31 recipients, respectively. Identifying the patients with the highest chances of survival has direct application in the prioritization of resources and in donor matching. For patients where high-confidence prediction is not achieved, assigning a probability to their survival odds has potential applications in probabilistic decision support systems and in combination with other sources of information.

    Autosomal Recessive Osteopetrosis is a genetic disorder characterized by increased bone density due to lack of resorption by the osteoclasts. Genetic studies have widely unraveled the molecular basis of the most severe forms, while cases of intermediate severity are more difficult to characterize, probably because of a large heterogeneity. Here, we describe the use of exome sequencing in the molecular diagnosis of 2 siblings initially thought to be affected by “intermediate osteopetrosis”, which identified a homozygous mutation in the CTSK gene. Prompted by this finding, we tested by Sanger sequencing 25 additional patients addressed to us for recessive osteopetrosis and found CTSK mutations in 4 of them. In retrospect, their clinical and radiographic features were found to be compatible with, but not typical for, Pycnodysostosis. We sought to identify modifier genes that might have played a role in the clinical manifestation of the disease in these patients, but our results were not informative. In conclusion, we underline the difficulties of differential diagnosis in some patients whose clinical appearance does not fit the classical malignant or benign picture and recommend that CTSK gene be included in the molecular diagnosis of high bone density conditions.

    Very little is known about how the spa gene mutates over time in methicillin-resistant Staphylococcus aureus (MRSA) from the same patient. Copenhagen is an area with low prevalence of MRSA but with high variability in spa types. We collected 1536 MRSA isolates from 319 patients during a 5-year...... period and found spa type alterations in 30 MRSA isolates (2%) from 13 patients (4%). The alteration most often seen was the deletion of repeats followed by repeat duplication and point mutation....

    : Patients with International Classification of Diseases (10th edition [ICD-10]) diagnoses of hypopituitarism, or other diagnoses of pituitary disorders assumed to be associated with an increased risk of hypopituitarism, recorded in the DNPR during 2000-2012 were identified. Medical records were reviewed...... to confirm or disprove hypopituitarism. RESULTS: Hypopituitarism was confirmed in 911 patients. In a candidate population of 1,661, this yielded an overall positive predictive value (PPV) of 54.8% (95% confidence interval [CI]: 52.4-57.3). Using algorithms searching for patients recorded at least one, three...... or five times with a diagnosis of hypopituitarism (E23.0x) and/or at least once with a diagnosis of postprocedural hypopituitarism (E89.3x), PPVs gradually increased from 73.3% (95% CI: 70.6-75.8) to 83.3% (95% CI: 80.7-85.7). Completeness for the same algorithms, however, decreased from 90.8% (95% CI: 88...

    OBJECTIVE Hydrocephalus remains one of the more common pathologies managed in pediatric neurosurgical units. Endoscopic third ventriculostomy (ETV) has an advantage over ventriculoperitoneal shunting as it enables patients to remain device free. Multiple shunt devices with various valve designs exist, with no one valve proven to be superior to another. The aim of this study was to describe the management of hydrocephalus and its long-term outcome. METHODS The authors retrospectively reviewed the medical records of all patients who had been treated for hydrocephalus at the Hôpital Necker-Enfants Malades in the period from 1985 to 1995. RESULTS Nine hundred seventy-five children had been treated for hydrocephalus. The mean follow-up was 11 ± 7.4 years (mean ± standard deviation). The most common cause of hydrocephalus was tumor related (32.3%), followed by malformative (24.5%) and inflammatory (20.9%) causes. Two hundred eighty patients underwent ETV as the first-line treatment. The procedure was effective in controlling hydrocephalus due to posterior fossa tumors and aqueductal stenosis. Six hundred ninety-five children had initial shunt insertion, with the majority receiving an Orbis-Sigma valve (OSV). The overall OSV shunt survival was 70% at 1 year, 58% at 10 years, and 49% at 20 years. The most common cause for mechanical shunt failure was obstruction (50.7%). Overall shunt survival was statistically different between the OSV and the differential-pressure valve (p = 0.009). CONCLUSIONS Endoscopic third ventriculostomy is effective in the management of childhood hydrocephalus. Its success is directly related to the underlying pathology. In the long term, the OSV has significantly higher event-free shunt survival than the classic differential-pressure valve systems.

    Current surveillance guidelines for patients with long-standing ulcerative colitis (UC) recommend repeated colonoscopy with random biopsies, which is time-consuming, discomforting, and expensive. A less invasive strategy is to identify neoplasia by analyzing biomarkers from the more accessible rectum to predict the need for a full colonoscopy. The goal of this pilot study was to evaluate whether optical markers of rectal mucosa derived from a novel optical technique, partial-wave spectroscopic microscopy (PWS), could identify UC patients with high-grade dysplasia (HGD) or cancer (CA) present anywhere in their colon. Banked frozen nondysplastic mucosal rectal biopsies were used from 28 UC patients (15 without dysplasia and 13 with concurrent HGD or CA). The specimen slides were made using a touch prep method and underwent PWS analysis. We divided the patients into two groups: 13 as a training set and an independent 15 as a validation set. We identified six optical markers, ranked by measuring the information gain with respect to the outcome of cancer. The most effective markers were selected by maximizing the cross-validated training accuracy of a Naive Bayes classifier. The optimal classifier was applied to the validation data yielding 100% sensitivity and 75% specificity. Our results indicate that the PWS-derived optical markers can accurately predict UC patients with HGD/CA through assessment of rectal epithelial cells. By aiming for high sensitivity, our approach could potentially simplify the surveillance of UC patients and improve overall resource utilization by identifying patients with HGD/CA who should proceed with colonoscopy.

    2008-11-01

    This study combined driver-responsible accidents with on-board driving hours to examine the effect of consecutive driving on the accident risk of train operations. The data collected from the Taiwan Railway Administration for the period 1996-2006 was used to compute accident rates for varied accumulated driving hours for passenger and freight trains. The results showed that accident risk grew with increased consecutive driving hours for both passenger and freight trains, and doubled that of the first hour after four consecutive hours of driving. Additional accident risk was found for freight trains during the first hour due to required shunting in the marshalling yards where there are complex track layouts and semi-automatic traffic controls. Also, accident risk for train driving increased more quickly over consecutive driving hours than for automobile driving, and accumulated fatigue caused by high working pressure and monotony of the working environment are considered to be the part of the reason. To prevent human errors accidents, enhancing safety equipment, driver training programs, and establishing a sound auditing system are suggested and discussed.

    The aim of the study was to analyze the frequency and certain epidemiological characteristics of a consecutive series of conjoined twins born in Spain. We used data from the Spanish Collaborative Study of Congenital Malformations for the period April 1976 to 2006. Because the Spanish law permitting voluntary termination of pregnancies (TOP) when the fetus presented malformations was effective by the end of 1985, we analyzed the data in 4 periods, 2 before 1986 and 2 after. During the first period (1976-1979) only live births were recorded, whereas both still and live births were included in the other three (1980-1985, 1986-1995, and 1996-2006). In the present study, the cases were classified as symmetrical (16 pairs) and asymmetrical (1 pair) conjoined twins. Each pair of conjoined twins was considered as only one case for calculations, regardless of the type of union. Among a total of 2,281,604 consecutive births between 1980 and 2006, there were a total of 15 cases of symmetrical conjoined twins giving a frequency of 0.70 per 100,000 (1/152,107), whereas there was only 1 stillborn asymmetrical conjoined twin pair (0.04/100,000). Among the 13,418 consecutive stillborns surveyed, 6 cases of conjoined twins were identified (either symmetrical or asymmetrical) giving a frequency of 44.72 per 100,000, and 11 pairs were identified among the 2,425,583 total live births surveyed during the first period 1976 to 1979, a frequency of 0.45 per 100,000. Thus, the frequency among stillborn infants is 99.34 times higher than that observed among live births. However, the frequency for the total births (3 last periods) showed a decreasing trend from 1.47 per 100,000 birth in the first period (1980-1985) when TOP was illegal, to a value of 0.09 per 100,000 in the last period, more than 16-fold lower, probably because of the TOP of affected fetuses. Therefore, we consider that the frequencies observed in the period 1980 to 1985 are the basal values in our population. The most

    Interrogation of the electronic health record (EHR) using billing codes as a surrogate for diagnoses of interest has been widely used for clinical research. However, the accuracy of this methodology is variable, as it reflects billing codes rather than severity of disease, and depends on the disease and the accuracy of the coding practitioner. Systematic application of text mining to the EHR has had variable success for the detection of cardiovascular phenotypes. We hypothesize that the application of text mining algorithms to cardiovascular procedure reports may be a superior method to identify patients with cardiovascular conditions of interest. We adapted the Oracle product Endeca, which utilizes text mining to identify terms of interest from a NoSQL-like database, for purposes of searching cardiovascular procedure reports and termed the tool "PennSeek". We imported 282,569 echocardiography reports representing 81,164 individuals and 27,205 cardiac catheterization reports representing 14,567 individuals from non-searchable databases into PennSeek. We then applied clinical criteria to these reports in PennSeek to identify patients with trileaflet aortic stenosis (TAS) and coronary artery disease (CAD). Accuracy of patient identification by text mining through PennSeek was compared with ICD-9 billing codes. Text mining identified 7115 patients with TAS and 9247 patients with CAD. ICD-9 codes identified 8272 patients with TAS and 6913 patients with CAD. 4346 patients with AS and 6024 patients with CAD were identified by both approaches. A randomly selected sample of 200-250 patients uniquely identified by text mining was compared with 200-250 patients uniquely identified by billing codes for both diseases. We demonstrate that text mining was superior, with a positive predictive value (PPV) of 0.95 compared to 0.53 by ICD-9 for TAS, and a PPV of 0.97 compared to 0.86 for CAD. These results highlight the superiority of text mining algorithms applied to electronic

    Advances in suction-assisted lipectomy (SAL) include improved instrumentation, better understanding of fluid dynamics, and an improved concept of appropriate indications. The tumescent technique uses subcutaneous injection of isotonic fluid containing vasoconstrictive and analgesic agents and is proved to be safe, with low morbidity and mortality rates. Laser-assisted liposuction (LAL) using local infiltration of an anesthetic and no general anesthesia or sedation has been developed, with claims of fat destruction and skin tightening. This study aimed to review 1,000 consecutive cases of LAL and SAL performed with the patient under local anesthesia and to determine whether this represents a safe technique with few complications. During a period of 22 months, 581 consecutive patients (486 females and 95 males) underwent 1,000 LAL/SAL operations, 545 of whom had multiple procedures performed. None of the patients had a body mass index (BMI) higher than 30 kg/m2. The patients ranged in age from 18 to 62 years. The fat aspirate ranged from 50 to 1,400 ml. Patients were given an oral sedative, an antibiotic, and an analgesic. Ringer's lactate solution containing lidocaine and epinephrine was injected into the subcutaneous space. The 1,064-nm and/or 1,320-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser was used for laser lipolysis followed by SAL using standard and/or power-assisted liposuction (PAL) cannulas. The treated areas included the neck, triceps, male breast, midback, flanks, axilla, abdomen, mons pubis, thighs, presacrum, and knees. No patient was administered intravenous sedation or general anesthesia. The average number of areas treated was 1.8, and no major complications or mortalities were observed. There were three burns, two infections, one hematoma, and one seroma. A total of 73 secondary procedures were performed (7.3%). No tertiary procedures were required. For appropriately selected patients, comparable results can be obtained with an excellent

    Aim. Large food bits can get stuck in the esophagus and must be removed by endoscopy. In some cases, this can be difficult or unsafe. We describe a new and safe treatment for such patients. Materials and Methods. 100 consecutive patients were referred to Akershus University Hospital with impacted food in the esophagus. In 36 patients (36%), the food passed spontaneously. In 59 (92%) of the remaining 64 patients, the food was removed by endoscopic intervention. In the last five patients, endoscopic removal was judged difficult or unsafe. These patients received the new treatment: one capsule Creon 10000 IU dissolved in 30 mL of Coca-Cola administered by a nasooesophageal tube four times daily for 2-3 days. Results. Of the 59 patients treated with endoscopic procedure, complications occurred in four (7%): three bleedings and one perforation of the esophagus. In five patients treated with Coca-Cola and Creon, the food had either passed or was soft after 2-3 days and could easily be removed. Conclusion. The treatment of choice of impacted food in the esophagus is endoscopic removal. In cases where this is difficult, we recommend treatment with Coca-Cola and Creon for 2-3 days before complications occur.

    The technology exists for the migration of healthcare data from its archaic paper-based system to an electronic one, and, once in digital form, to be transported anywhere in the world in a matter of seconds. The advent of universally accessible healthcare data has benefited all participants, but one of the outstanding problems that must be addressed is how the creation of a standardized nationwide electronic healthcare record system in the United States would uniquely identify and match a composite of an individual's recorded healthcare information to an identified individual patients out of approximately 300 million people to a 1:1 match. To date, a few solutions to this problem have been proposed that are limited in their effectiveness. We propose the use of biometric technology within our fingerprint, iris, retina scan, and DNA (FIRD) framework, which is a multiphase system whose primary phase is a multilayer consisting of these four types of biometric identifiers: 1) fingerprint; 2) iris; 3) retina scan; and 4) DNA. In addition, it also consists of additional phases of integration, consolidation, and data discrepancy functions to solve the unique association of a patient to their medical data distinctively. This would allow a patient to have real-time access to all of their recorded healthcare information electronically whenever it is necessary, securely with minimal effort, greater effectiveness, and ease.

    This study was conducted to identify mutations in the homogentisate 1,2 dioxygenase gene (HGD) in alkaptonuria patients among Jordanian population. Blood samples were collected from four alkaptonuria patients, four carriers, and two healthy volunteers. DNA was isolated from peripheral blood. All 14 exons of the HGD gene were amplified using the polymerase chain reaction (PCR) technique. The PCR products were then purified and analyzed by sequencing. Five mutations were identified in our samples. Four of them were novel C1273A, T1046G, 551-552insG, T533G and had not been previously reported, and one mutation T847C has been described before. The types of mutations identified were two missense mutations, one splice site mutation, one frameshift mutation, and one polymorphism. We present the first molecular study of the HGD gene in Jordanian alkaptonuria patients. This study provides valuable information about the molecular basis of alkaptonuria in Jordanian population.

    To construct a prognostic index based on nailfold capillaroscopic examinations that is capable of predicting the 5-year transition from isolated Raynaud's phenomenon (RP) to RP secondary to scleroderma spectrum disorders (SSDs). The study involved 104 consecutive adult patients with a clinical history of isolated RP, and the index was externally validated in another cohort of 100 patients with the same characteristics. Both groups were followed up for 1-8 years. Six variables were examined because of their potential prognostic relevance (branching, enlarged and giant loops, capillary disorganization, microhemorrhages, and the number of capillaries). The only factors that played a significant prognostic role were the presence of giant loops (hazard ratio [HR] 2.64, P = 0.008) and microhemorrhages (HR 2.33, P = 0.01), and the number of capillaries (analyzed as a continuous variable). The adjusted prognostic role of these factors was evaluated by means of multivariate regression analysis, and the results were used to construct an algorithm-based prognostic index. The model was internally and externally validated. Our prognostic capillaroscopic index identifies RP patients in whom the risk of developing SSDs is high. This model is a weighted combination of different capillaroscopy parameters that allows physicians to stratify RP patients easily, using a relatively simple diagram to deduce the prognosis. Our results suggest that this index could be used in clinical practice, and its further inclusion in prospective studies will undoubtedly help in exploring its potential in predicting treatment response.

    The study's purpose is to report the technical and clinical outcomes of a patient cohort that underwent vertebral artery ostium stent placement for atherosclerotic stenosis. We retrospectively analyzed a prospectively collected database of neurointerventional procedures performed at a single center from 1999 to 2005. Outcome measures included recurrent transient neurological deficits (TNDs), stroke, and death. Kaplan-Meier analysis was used to estimate stroke- and/or death-free survival at 12 months. Cox proportional hazard was used to identify risk factors for recurrent vertebrobasilar ischemic events. Seventy-two patients with 77 treated vertebral ostial lesions were included. The 30-day stroke and/or death rate was 5.2% (n = 4), although no event was directly related to the vertebral ostium stent placement. Three procedure-related strokes were secondary to attempted stent placement at other sites (one carotid artery and two basilar arteries), and the one death was secondary to the presenting stroke severity. The mean clinical follow-up time available for 66 patients was 9 months. There were 14 TNDs (21%), two strokes (3%), and two deaths (3%) recorded in the follow-up. Recurrent vertebrobasilar ischemic events occurred in nine patients (seven TNDs and two strokes). No recurrent stroke and/or deaths were related to the treated vertebral ostium. Stroke- and/or death-free survival rate (including periprocedural stroke and/or death) was 89 ± 5% at 12 months. No vascular risk factor was significantly associated with recurrent vertebrobasilar ischemic events. Vertebral artery ostium stent placement can be safely and effectively performed with a low rate of recurrent stroke in the territory of the treated vessel. Patients who also underwent attempted treatment of a tandem intracranial stenosis appeared to be at highest risk for periprocedure stroke. (orig.)

    The present study explored how seizure clusters may be defined for those with psychogenic nonepileptic seizures (PNES), a topic for which there is a paucity of literature. The sample was drawn from a multisite randomized clinical trial for PNES; seizure data are from participants' seizure diaries. Three possible cluster definitions were examined: 1) common clinical definition, where ≥3 seizures in a day is considered a cluster, along with two novel statistical definitions, where ≥3 seizures in a day are considered a cluster if the observed number of seizures statistically exceeds what would be expected relative to a patient's: 1) average seizure rate prior to the trial, 2) observed seizure rate for the previous seven days. Prevalence of clusters was 62-68% depending on cluster definition used, and occurrence rate of clusters was 6-19% depending on cluster definition. Based on these data, clusters seem to be common in patients with PNES, and more research is needed to identify if clusters are related to triggers and outcomes. Copyright © 2017 Elsevier Inc.

    2017-12-01

    Within the context of growing concerns about a potential oversupply of occupational therapist, this research examines when, where and how long new graduates take to gain employment and identifies influences upon the health and university systems. A mixed method research design, using an online survey was adopted to investigate the topic. Two consecutive cohorts of graduates from a single university program were invited to participate. Seventy-five (58%) responses were received, with 63 (84%) currently employed in an occupational therapy role. Of the 12 (16%) not employed, only 3 (4%) described themselves as actively seeking employment in an occupational therapy role. A wide spread of employment settings and scope of practice areas was reported. Findings suggest that occupational therapy graduates are gaining employment in a range of settings and practice areas, relatively quickly. This research adds evidence to the conversation around graduate employment within a region of Australia. The Australian population, health system and university changes are possible factors influencing employment.

    Autosomal Recessive Osteopetrosis is a genetic disorder characterized by increased bone density due to lack of resorption by the osteoclasts. Genetic studies have widely unraveled the molecular basis of the most severe forms, while cases of intermediate severity are more difficult to characterize, probably because of a large heterogeneity. Here, we describe the use of exome sequencing in the molecular diagnosis of 2 siblings initially thought to be affected by "intermediate osteopetrosis", which identified a homozygous mutation in the CTSK gene. Prompted by this finding, we tested by Sanger sequencing 25 additional patients addressed to us for recessive osteopetrosis and found CTSK mutations in 4 of them. In retrospect, their clinical and radiographic features were found to be compatible with, but not typical for, Pycnodysostosis. We sought to identify modifier genes that might have played a role in the clinical manifestation of the disease in these patients, but our results were not informative. In conclusion, we underline the difficulties of differential diagnosis in some patients whose clinical appearance does not fit the classical malignant or benign picture and recommend that CTSK gene be included in the molecular diagnosis of high bone density conditions.

    After a first anterior approach to the lumbar spine, formation of adhesions of soft tissues to the spine increases the surgical difficulties and potential for iatrogenic injury during the revision exposure. The objective of this study was to identify the intraoperative difficulties and postoperative complications associated with revision anterior lumbar spine procedures in a single institution. This is a retrospective review of 25 consecutive anterior revision lumbar surgeries in 22 patients (7 men and 15 women) operated on between 1998 and 2011. Patients with trauma or malignancies were excluded. The mean age of the patients at the time of revision surgery was 56 years (range 20-80 years). The complications were analyzed depending on the operative level and the time between the index surgery and the revision. Six major complications (five intraoperatively and one postoperatively) occurred in five patients (20 %): three vein lacerations (12 %) and two ureteral injuries (8 %), despite the presence of a double-J ureteral stent. The three vein damages were repaired or ligated by a vascular surgeon. One of the two ureteral injuries led to a secondary nephrectomy after end-to-end anastomosis failure; the other necessitated secondary laparotomy for small bowel obstruction. Anterior revision of the lumbar spine is technically challenging and is associated with a high rate of vascular or urologic complications. Therefore, the potential complications of the procedure must be weighted against its benefits. When iterative anterior lumbar approach is mandatory, exposure should be performed by an access surgeon in specialized centers that have ready access to vascular and urologic surgeons.

    10-20% of APL patients relapse and the challenge remains to early identify these patients to improve survival rate. We report PML-RARalpha transcript detection by RQ-PCR in 260 consecutive APL patients (n = 970 samples). 223 patients with samples of sufficient RNA quality to demonstrate they reached molecular remission were monitored for MRD. During follow-up, 38 of these patients were tested positive for PML-RARalpha mRNA. 13 out of the 38 patients (34%) effectively developed hematological relapse. In the first positive sample, specific PML-RARalpha NCN thresholds over which, or under which, patients could effectively be predicted to relapse or not, were identified and subsequently validated in a second cohort.

    Assessing the likelihood of a variceal versus nonvariceal source of upper gastrointestinal bleeding (UGIB) guides therapy, but can be difficult to determine on clinical grounds. The objective of this study was to determine if there are easily ascertainable clinical and laboratory findings that can identify a patient as low risk for a variceal source of hemorrhage. This was a retrospective cohort study of adult ED patients with UGIB between January 2008 and December 2014 who had upper endoscopy performed during hospitalization. Clinical and laboratory data were abstracted from the medical record. The source of the UGIB was defined as variceal or nonvariceal based on endoscopic reports. Binary recursive partitioning was utilized to create a clinical decision rule. The rule was internally validated and test characteristics were calculated with 1,000 bootstrap replications. A total of 719 patients were identified; mean age was 55 years and 61% were male. There were 71 (10%) patients with a variceal UGIB identified on endoscopy. Binary recursive partitioning yielded a two-step decision rule (platelet count > 200 × 10 9 /L and an international normalized ratio [INR] study must be externally validated before widespread use, patients presenting to the ED with an acute UGIB with platelet count of >200 × 10 9 /L and an INR of upper gastrointestinal hemorrhage. © 2017 by the Society for Academic Emergency Medicine.

  5. The use of port-a-caths in adult patients with Lysosomal Storage Disorders receiving Enzyme Replacement Therapy-one centre experience

    Full Text Available Port-a-cath is a widely used device in patients with long-term venous access demand such as frequent or continuous administration of medications such as Enzyme Replacement Therapy (ERT, chemotherapy delivery, blood transfusions, blood products, and fluids. Patients with Lysosomal Storage Diseases (LSDs often require recurrent courses of ERT. We reviewed our experience of using port-a-caths in patients with LSDs with the focus on challenges and complications associated with these catheters. Among 245 adult patients who were treated with ERT, twenty patients (8.2% had a port-a-cath inserted due to poor venous access. Six patients were using their first port whereas five other patients had their port-a-caths replaced at least once. The remaining six patients had inactive port-a-caths. The majority of patients with active port-a-caths never missed more than one consecutive infusion, although one patient missed 2 consecutive infusions whilst on holiday. We identified significant gaps in patients' and their families' understanding of the management of port-a-caths and risks associated with them. It resulted in producing a leaflet and designing an educational program for our LSD patients.

    To assess results with NIV in acute hypercapneic respiratory failure and to identify outcome predictors. This was a retrospective observational study on consecutive patients presenting with acute type II respiratory failure and meeting criteria for NIV use over a 5 year period. Patients presenting with haemodynamic instability, inability to protect their airway, malignant arrhythmias and recent oesophageal surgery were excluded. Univariate and Multivariate regression analysis was used to determine the impact on survival. A p value of 35 Meq/L (adjusted Odds ratio 0.9; 95% CI 0.83, 0.98, p < 0.015) identified those less at risk for intubation. NIV was found to be both safe and effective in the management of acute hypercapneic respiratory failure.

    Many surgical interventions have emerged as effective means of restoring mechanical stability of the anterior column of the spine. The lateral extracavitary approach (LECA) allows for broad visualization and circumferential reconstruction of the spinal column. However, early reports demonstrated significant complication rates, protracted operative times, and prolonged hospitalizations. More recent reports have highlighted concerns for subsidence, particularly with expandable cages. Our work seeks to describe a single-surgeon consecutive series of patients undergoing LECA for thoracic corpectomy. Specifically, the objective was to explore the surgical considerations, clinical and radiographic outcomes, and complication profile of this approach. A retrospective study examined data from 17 consecutive patients in whom single or multi-level corpectomy was performed via a LECA by a single surgeon. Vertebral body replacement was achieved with either a static or expandable titanium cage. The Karnofsky Performance Scale (KPS) was utilized to assess patient functional status before and after surgery. Radiographic outcomes, particularly footplate-to-body ratio and subsidence, were assessed on CT imaging at 6 weeks after surgery and at follow-up of at least 6 months. The majority of patients had post-operative KPS scores consistent with functional independence (≥70, 12/17 patients, 71%). Fourteen patients had improved or maintained function by last follow-up. In both groups, all patients had a favorable footplate-to-body ratio, and rates of subsidence were similar at both time points. Notably, the overall complication rate (24%) was significantly lower than that published in the literature, and no patient suffered a pneumothorax that required placement of a thoracostomy tube. The LECA approach for anterior column reconstruction with static or expandable cages is an important surgical consideration with favorable surgical parameters and complication rates. Further, use of

    In patients with a glioblastoma (GBM), few unselected data exists using actual standard adjuvant treatment and contemporary surgical techniques like iMRI. Aim of study is to assess impact of EoR and recurrent surgery on survival and outcome. We assessed a consecutive unselected series of 170 surgeries for GBM (2008-2014) applying intraoperative MRI (iMRI). All patients received adjuvant radio-chemo-therapy. Overall-survival (OS), progression free survival (PFS), complications and new permanent neurological deficits (nPND) were assessed. Uni- and multivariate-cox-regression-models were calculated. Mean follow-up was 40mo. GTR was intended in 82% and achieved in 77% of these cases. A nPND was found in 7% of patients. In multivariate cox-regression, GTR (HR:0.6, Psurgery and recurrent surgery. Concerning OS, in multivariate assessment an un-methylated MGMT-promotor (HR2.0, Psurgery for recurrent disease was positively associated with OS (HR0.6, PSurgery in a contemporary setup using iMRI, brain mapping and modern adjuvant treatment, has a higher OS and lower complication rates as previously published. A maximum but safe resection should be the goal of surgery since a perioperative complication significantly decreases OS. Recurrent surgery has a beneficial effect on OS without an increase of complications.

    Use of cumulative mortality adjusted for case mix in patients with acute myocardial infarction for early detection of variation in clinical practice. Observational study. 20 hospitals across the former Yorkshire region. All 2153 consecutive patients with confirmed acute myocardial infarction identified during three months. Variable life-adjusted displays showing cumulative differences between observed and expected mortality of patients; expected mortality calculated from risk model based on admission characteristics of age, heart rate, and systolic blood pressure. The performance of two individual hospitals over three months was examined as an example. One, the smallest district hospital in the region, had a series of 30 consecutive patients but had five more deaths than predicted. The variable life-adjusted display showed minimal variation from that predicted for the first 15 patients followed by a run of unexpectedly high mortality. The second example was the main tertiary referral centre for the region, which admitted 188 consecutive patients. The display showed a period of apparently poor performance followed by substantial improvement, where the plot rose steadily from a cumulative net lives saved of -4 to 7. These variations in patient outcome are unlikely to have been revealed during conventional audit practice. Variable life-adjusted display has been integrated into surgical care as a graphical display of risk-adjusted survival for individual surgeons or centres. In combination with a simple risk model, it may have a role in monitoring performance and outcome in patients with acute myocardial infarction.

    Dynamic stabilization of the degenerated spine was invented to overcome the negative side effects of fusion surgery like adjacent segment degeneration. Amongst various different implants DSS(®) is a pedicle-based dynamic device for stabilizing the spine and preserving motion. Nearly no clinical data of the implant have been reported so far. The current analysis presents results from a single spine surgeon who has been using DSS(®) for the past 5 years and recorded all treatment and outcome data in the international Spine Tango registry. From the prospectively documented overall patient pool 436 cases treated with DSS(®) could be identified. The analysis was enhanced with a mailing of COMI patient questionnaires for generating longer-term follow-ups up to 4 years. 387 patients (189 male, 198 female; mean age 67.3 years) with degenerative lumbar spinal disease including degenerative spondylolisthesis (6.1 %) could be evaluated. The type of degeneration was mainly spinal stenosis (89.9 %). After a mean follow-up of 1.94 years, the COMI score and NRS back and leg pain improved significantly and to a clinically relevant extent. The postoperative trend analysis could not determine a relevant deterioration of these outcomes until 4 years postoperative. 10 patients were revised (2.6 %) and the implant was removed; in most cases, a fusion was performed. Another 5 cases (1.3 %) had an extension of the dynamic stabilization system to the adjacent level. 84.2 % of patients rated that the surgery had helped a lot or had helped. The results of this large consecutive series with a follow-up up to 4 years could demonstrate a good and stable clinical outcome after posterior dynamic stabilization with DSS(®). For degenerative diseases of the lumbar spine, this treatment seems to be a valid alternative to fusion surgery.

    Frail and physically or mentally disabled patients frequently have difficulty in tolerating formal colonic investigations. The aims of this study were to evaluate the accuracy of minimal-preparation CT in identifying colorectal carcinoma in this population and to determine the clinical indications and radiological signs with the highest yield for tumour. The CT technique involved helical acquisition (10-mm collimation, 1.5 pitch) following 2 days of preparation with oral contrast medium only. The outcome of 4 years of experience was retrospectively reviewed. The gold standards were pathological and cancer registration records, together with colonoscopy and barium enema when undertaken, with a minimum of 15 months follow-up. One thousand seventy-seven CT studies in 1031 patients (median age 80 years) were evaluated. CT correctly identified 83 of the 98 colorectal carcinomas in this group but missed 15 cases; sensitivity and specificity (with 95% confidence interval) 85% (78-92%) and 91% (90-93%), respectively. Multivariate analysis identified: (a) a palpable abdominal mass and anaemia to be the strongest clinical indications, particularly in combination (p<0.0025); and (b) lesion width and blurring of the serosal margin of lesions to be associated with tumours (p<0.0001). Computed tomography has a valuable role in the investigation of frail and otherwise disabled patients with symptoms suspicious for a colonic neoplasm. Although interpretation can be difficult, the technique is able to exclude malignancy with good accuracy. (orig.)

    The consecutive matching striae (CMS) numeric criteria for firearm and toolmark identifications have been widely accepted by forensic examiners, although there have been questions concerning its observer subjectivity and limited statistical support. In this paper, based on signal processing and extraction, a model for the automatic and objective counting of CMS is proposed. The position and shape information of the striae on the bullet land is represented by a feature profile, which is used for determining the CMS number automatically. Rapid counting of CMS number provides a basis for ballistics correlations with large databases and further statistical and probability analysis. Experimental results in this report using bullets fired from ten consecutively manufactured barrels support this developed model. Published by Elsevier Ireland Ltd.

    A design to determine the minimum distance between the consecutive carriers at the trajectory of gamma irradiators IR-200K is implemented. Equilibrium between centrifugal force of a moving carrier in circular trajectory and its gravity force as well as carrier dimensions are used as parameters in determining such a minimum distance. The minimum distance between the consecutive carriers in the design is defined 1.2 meters. The distance is 11.5% greater than the minimum distance theoretically calculated, namely 1,076 meters. Errors tolerance in construction/installation of the trajectory and other unexpected things during irradiator's operation are part of the consideration to enlarge the minimum distance from its theoretical value. The distance between the consecutive carriers will not affect throughput and efficiency of using radiation due to the straight trajectory segments do not need to follow such the minimum distance between the carriers, as the trajectory segments around the i radiation sources are straight.

    Psychomotor agitation is a common event in psychiatric emergency services (PES) with a prevalence of approximately 10 %. There is no general consensus on to how to manage psychomotor agitation; benzodiazepines, typical antipsychotics and now atypical antipsychotics have demonstrated similar efficacy. The aim of our study was to describe the epidemiology and clinical management of agitation in "real-life" in a psychiatric emergency service. A naturalistic study was performed in acutely agitated patients recruited consecutively in a psychiatric emergency service. Demographics, clinical and therapeutic characteristics were analyzed. Efficacy was assessed by the Excitement Component of the Positive and Negative Syndrome Scale (PANSS-EC) and the Agitation-Calmness Evaluation Scale (ACES). Pragmatic variables such as the need for second pharmacological intervention and the need for physical restraints were assessed. The study included 100 patients with psychomotor agitation. Mean age was 36.2 % and 54% were women. The most prevalent diagnoses were psychotic disorder (48 %) and personality disorder (24 %). Physical restraint was required in 39 % of patients and 52 % accepted oral treatment. Haloperidol was the most frequent oral treatment and olanzapine was the most frequent intramuscular treatment. A naturalistic approach provides data based on clinical reality in psychiatric emergency services. Strict research designs of clinical trials of efficacy imply sample selection biases and are generally distanced from the clinical reality. Atypical antipsychotics have become the first-line treatment in acute agitation

The CT features between large FOP (>3 cm, n = 27) and small FOP (≤3 cm, n = 18) were compared. Results: FOP lesions predominately located in peripheral lungs (86.7%), with the right lower lobe being most common lobe (44.4%). No lesion mainly located in the inner 1/3 of lungs. All large lesions were polygon in shape and had an irregular margin, while small lesions were more likely to be round or oval with an irregular or smooth border. Air bronchogram or small bubble-like lucency was present in majority of the lesions. 42.2% of lesions had incompact internal structure with inhomogeneous density besides air component. Most lesions were associated with a contraction or convergence of surrounding vessels; while no pulmonary vessel was interrupted abruptly by a small FOP lesion. Majority of large lesions had broad contact with the pleura, while only one patient had mild pleural effusion. Mild mediastinal lymph nodes enlargement was present in about 1/5 of the patients. Conclusion: Compared with the known CT features of lung cancer, our results suggest differential diagnosis can often be made for large FOP, while small FOP may resemble lung cancer.

    The aim of this study was to document vascular complications that occurred following cadaveric and living donor kidney transplants in order to assess the overall incidence of these complications at our center as well as to identify possible risk factors. In a retrospective cohort study, 1500 consecutive renal transplant recipients who received a living or cadaveric donor kidney between December 1988 and July 2006 were evaluated. The study was performed at the Nemazee Hospital, Shiraz, Iran. The assessment of the anatomy and number of renal arteries as well as the incidence of vascular complications was made by color doppler ultrasonography, angiography, and/or surgical exploration. Clinically apparent vascular complications were seen in 8.86% of all study patients (n = 133) with the most frequent being hemorrhage (n = 91; 6.1%) followed by allograft renal artery stenosis (n = 26; 1.7%), renal artery thrombosis (n = 9; 0.6%), and renal vein thrombosis (n = 7; 0.5%). Vascular complications were more frequent in recipients of cadaveric organs than recipients of allografts from living donors (12.5% vs. 7.97%; P0.017). The occurrence of vascular complications was significantly more frequent among recipients of renal allografts with multiple arteries when compared with recipients of kidneys with single artery (12.3% vs. 8.2%; P0.033). The same was true to venous complications as well (25.4% vs. 8.2%; P< 0.001). Our study shows that vascular complications were more frequent in allografts with multiple renal blood vessels. Also, the complications were much less frequent in recipients of living donor transplants. (author)

    Background: Septic arthritis in the sternoclavicular (SC) region is rare and may be difficult to diagnose clinically and radiologically. It mainly affects immunocompromised persons, and can clinically be misinterpreted as tumor and rheumatic disorders. Lacking radiological reference standard, a multimodality approach may contribute to a prolonged diagnostic process. Purpose: To describe the diagnostics of septic arthritis in the SC region. Material and Methods: Between 2001 and 2011, 10 patients with Staphylococcus infection in the SC region were investigated in our institution. Clinical, biochemical, radiological, and microbiological findings were studied retrospectively; all CT and MR examinations were re-evaluated. Results: Initial radiography in nine patients and ultrasonography in six patients were inconclusive resulting in supplementary MRI and/or CT. Five patients examined by MRI were immediately diagnosed with septic arthritis whereas CT in five patients led to the diagnosis in only one. Three were subsequently diagnosed by MRI, but delayed more than 2.5 weeks, and one was diagnosed by surgery. The median time to diagnosis was 1.5 weeks. The delay caused by imaging was 0 days to 11.5 weeks (median 0 days). By re-evaluation overlooked complications included mediastinitis in seven patients (three diffuse, four localized), and abscesses and pleuritis each in four patients. Conclusion: Awareness of infection in the SC region is important to avoid diagnostic delay. MRI is proposed as the initial imaging procedure

    Care for patients with long term conditions is often characterized as fragmented and ineffective, and fails to engage the resources of patients and their families in the care process. Information and communication technology can potentially help bridge the gap between patients' lives and resources and services provided by professionals. However, there is little attention on how to identify and incorporate the patients' individual needs, values, preferences and care goals into the digitally driven care settings. We conducted a case study with healthcare professionals and patients participated applying a service design thinking approach. The participants could elaborate some personal goals of patients with long term condition which can potentially be incorporated in digitally driven care plans using examples from their own experiences.

    Molecular pathways regulating melanoma initiation and progression are potential targets of therapeutic development for this aggressive cancer. Identification and molecular analysis of these pathways in patients has been primarily restricted to targeted studies on individual proteins. Here, we report the most comprehensive analysis of formalin-fixed paraffin-embedded human melanoma tissues using quantitative proteomics. From 61 patient samples, we identified 171 proteins varying in abundance among benign nevi, primary melanoma, and metastatic melanoma. Seventy-three percent of these proteins were validated by immunohistochemistry staining of malignant melanoma tissues from the Human Protein Atlas database. Our results reveal that molecular pathways involved with tumor cell proliferation, motility, and apoptosis are mis-regulated in melanoma. These data provide the most comprehensive proteome resource on patient melanoma and reveal insight into the molecular mechanisms driving melanoma progression.

    Safety climate refers to shared perceptions of what an organization is like with regard to safety, whereas safety culture refers to employees' fundamental ideology and orientation and explains why safety is pursued in the manner exhibited within a particular organization. Although research has sought to identify opportunities for improving safety outcomes by studying patterns of variation in safety climate, few empirical studies have examined the impact of organizational characteristics such as culture on hospital safety climate. This study explored how aspects of general organizational culture relate to hospital patient safety climate. In a stratified sample of 92 U.S. hospitals, we sampled 100% of senior managers and physicians and 10% of other hospital workers. The Patient Safety Climate in Healthcare Organizations and the Zammuto and Krakower organizational culture surveys measured safety climate and group, entrepreneurial, hierarchical, and production orientation of hospitals' culture, respectively. We administered safety climate surveys to 18,361 personnel and organizational culture surveys to a 5,894 random subsample between March 2004 and May 2005. Secondary data came from the 2004 American Hospital Association Annual Hospital Survey and Dun & Bradstreet. Hierarchical linear regressions assessed relationships between organizational culture and safety climate measures. Aspects of general organizational culture were strongly related to safety climate. A higher level of group culture correlated with a higher level of safety climate, but more hierarchical culture was associated with lower safety climate. Aspects of organizational culture accounted for more than threefold improvement in measures of model fit compared with models with controls alone. A mix of culture types, emphasizing group culture, seemed optimal for safety climate. Safety climate and organizational culture are positively related. Results support strategies that promote group orientation and

    Acquired auricular deformities may diminish facial esthetics and cause psychological distress. The aim of this article is to provide an overview of the type of injuries and applied reconstructive techniques in a large academic hospital in The Netherlands. A retrospective chart review was conducted for the last 105 patients who underwent auricular reconstruction for an acquired deformity. Data concerning gender, affected side, cause of injury, anatomical region, the previous and further surgeries, type of cartilage, and skin cover used were collected and analyzed. 105 patients were included. Acquired auricular deformities were mainly caused by bite injuries (22 %), traffic accidents (17 %), burns (9.5 %), and post-otoplasty complications (9.5 %). The upper third of the auricle was most often injured (41 %), followed by the entire auricle (19 %). 70 % of cases required reconstruction with costal cartilage. The most common form of cutaneous cover was a postauricular skin flap (40 % of cases). This study gives a complete overview of causes and treatment of acquired auricular deformities. The results are comparable with the results of similar studies found in literature. Bite wounds are the leading cause of acquired auricular injuries. The upper third is most commonly affected. In the largest percentage of reconstructions, costal cartilage and a postauricular flap were used to correct the deformity.

    Vinflunine is a new microtubule inhibitor of the vinca-alkaloid family. It is marketed in transitional cell carcinoma of urothelial tract as a 20 min infusion given every 3 weeks in Europe. In this phase I study, vinflunine was administered to patients with advanced malignancies as hard capsules given twice a day on days 1-2 every week, with 3 weeks cycles. Serial blood samples were collected during the first cycle for pharmacokinetic investigations. Thirty-six patients (pts) were treated at 6 dose levels 150 (3 pts), 190 (3 pts), 230 (8 pts), 300 mg/day (6 pts) and then 250 (3 pts) and 270 mg/day (13 pts). The Maximal Tolerated Dose (MTD) was reached at 300 mg/day where 2 patients out of 6 experienced a dose limiting toxicity (febrile neutropenia with diarrhea). The lower dose level of 270 mg/day was the recommended dose (RD), the toxicity profile being mainly anaemia, neutropenia, fatigue and constipation. The pharmacokinetic analysis demonstrated the adequacy of the flat-fixed dosing regimen, as no correlation between clearance of vinflunine and body surface area was evidenced. Blood concentrations and exposure increased with dose, and a pharmacokinetic accumulation was observed, which is consistent with the terminal half-life of the compounds. The inter-individual exposure variability at the RD was 35%. Repeated weekly administration of oral vinflunine is feasible and exhibits a moderate inter-individual PK variability. The MTD was achieved at 300 mg/day given for 2 consecutive days. According to the protocol rules, the RD was established at 270 mg/day.

    Molecular alterations preceding endometrial and ovarian cancer and the sequence of events are unknown. Consecutive specimens from lifelong surveillance for Lynch syndrome provides a natural setting to address such questions. To molecularly define the multistep gynecological tumorigenesis, DNA mismatch repair gene mutation carriers with endometrial or ovarian carcinoma or endometrial hyperplasia were identified from a nation-wide registry and endometrial biopsy specimens taken from these individuals during 20 years of screening were collected. A total of 213 endometrial and ovarian specimens from Lynch syndrome individuals and 197 histology-matched (non-serous) samples from sporadic cases were available for this investigation. The specimens were profiled for markers linked to endometrial and ovarian tumorigenesis, including ARID1A protein expression, mismatch repair status, and tumor suppressor gene promoter methylation. In Lynch syndrome-associated endometrial and ovarian carcinomas, ARID1A protein was lost in 61-100% and mismatch repair was deficient in 97-100%, compared to 0-17% and 14-44% in sporadic cases (P = 0.000). ARID1A loss appeared in complex hyperplasia and deficient mismatch repair and tumor suppressor gene promoter methylation in histologically normal endometrium. Despite quantitative differences between Lynch syndrome and sporadic cases, ARID1A expression, mismatch repair, and tumor suppressor gene promoter methylation divided endometrial samples from both patient groups into three categories of increasing abnormality, comprising normal endometrium and simple hyperplasia (I), complex hyperplasia with or without atypia (II), and endometrial cancer (III). Complex hyperplasias without vs. with atypia were molecularly indistinguishable. In conclusion, surveillance specimens from Lynch syndrome identify mismatch repair deficiency, tumor suppressor gene promoter methylation, and ARID1A loss as early changes in tumor development. Our findings are

    To evaluate the predictive value of brain natriuretic peptide (BNP) for assessment of cardiac risk before non-cardiac surgery. Consecutively treated patients (947 men, 643 women) whose BNP was measured before non-cardiac surgery were studied. Clinical and ECG variables were evaluated to identify predictors of postoperative cardiac events. Events occurred in 6% of patients: 21 cardiac deaths, 20 non-fatal myocardial infarctions, 41 episodes of pulmonary oedema and 14 patients with ventricular tachycardia. All of these patients had raised plasma BNP concentrations (best cut-off point 189 pg/ml). The only independent predictor of postoperative events was BNP (odds ratio 34.52, 95% confidence interval (CI) 17.08 to 68.62, p 300 pg/ml); postoperative event rates were 0%, 5%, 12% and 81%, respectively. In this population of patients evaluated before non-cardiac surgery, BNP is an independent predictor of postoperative cardiac events. BNP > 189 pg/ml identified patients at highest risk.

    This study seeks to generate analytic insights into risk management and probability of an identifiable primary immunodeficiency defect. The Jeffrey Modell Centers Network database, Jeffrey Modell Foundation's 10 Warning Signs, the 4 Stages of Testing Algorithm, physician-reported clinical outcomes, programs of physician education and public awareness, the SPIRIT® Analyzer, and newborn screening, taken together, generates P values of less than 0.05%. This indicates that the data results do not occur by chance, and that there is a better than 95% probability that the data are valid. The objectives are to improve patients' quality of life, while generating significant reduction of costs. The advances of the world's experts aligned with these JMF programs can generate analytic insights as to risk management and probability of an identifiable primary immunodeficiency defect. This strategy reduces the uncertainties related to primary immunodeficiency risks, as we can screen, test, identify, and treat undiagnosed patients. We can also address regional differences and prevalence, age, gender, treatment modalities, and sites of care, as well as economic benefits. These tools support high net benefits, substantial financial savings, and significant reduction of costs. All stakeholders, including patients, clinicians, pharmaceutical companies, third party payers, and government healthcare agencies, must address the earliest possible precise diagnosis, appropriate intervention and treatment, as well as stringent control of healthcare costs through risk assessment and outcome measurement. An affected patient is entitled to nothing less, and stakeholders are responsible to utilize tools currently available. Implementation offers a significant challenge to the entire primary immunodeficiency community.

    Stereotactic ablative body radiotherapy (SABR) is currently used to treat oligometastases, but the optimum dose/fractionation schedule is unknown. In this study, we evaluated outcomes after single fraction SABR in patients with oligometastatic disease. Single institutional retrospective review of patients treated with single fraction SABR for one to three oligometastases between 2010 and 2015. The primary outcome was freedom from widespread disease defined as distant recurrence not amenable to surgery or SABR; or recurrence with four or more metastases. In total, 186 treatments were delivered in 132 patients. The two most common target sites were lung (51%) and bone (40%). The most frequent single fraction prescription dose was 26 Gy (47%). The most common primary malignancy was genitourinary (n = 46 patients). Freedom from widespread disease was 75% at 1 year (95% confidence interval 67-83%) and 52% at 2 years (95% confidence interval 42-63%). Freedom from local progression at 1 year was 90% (95% confidence interval 85-95%) and at 2 years was 84% (95% confidence interval 77-91%). A compression fracture of the lumbar vertebra was the only grade 3+ treatment-related toxicity. Single fraction SABR is associated with a high rate of freedom from widespread disease, favourable local control and low toxicity comparable with historic multi-fraction SABR reports.

    BACKGROUND: Patients with large intracerebral haematomas (ICH) from aneurysm rupture often present in a poor clinical condition and have a poor prognosis. Time delay for preoperative angiography might in some cases be unappealing. We evaluated the outcome after immediate haematoma removal...... and aneurysm occlusion without preoperative angiography. METHODS: We retrospectively identified 13 consecutive patients. We recorded clinical data and evaluated mortality and morbidity with the Glasgow Outcome Score (GOS) and Telephone Interview of Cognitive Status (TICS). FINDINGS: At follow up seven...... of thirteen patients had favourable outcome assessed by GOS. Three patients had severe disability and three patients died. None of the survived patients interviewed had impaired cognition. CONCLUSIONS: In patients presented in a critical state with aneurysmal ICH, emergency haematoma removal and aneurysm...

    We assessed clinical and early electrophysiological characteristics, in particular Generalized Periodic Epileptiform Discharges (GPEDs) patterns, of consecutive patients during a 1-year period, hospitalized in the Intensive Care Unit (ICU) after resuscitation following cardiac arrest (CA). Consecutive patients resuscitated from cardiac arrest (CA) with first EEG recordings within 48hours were included. Clinical data were collected from hospital records, in particular therapeutic hypothermia. Electroencephalograms (EEGs) were re-analyzed retrospectively. Sixty-two patients were included. Forty-two patients (68%) were treated with therapeutic hypothermia according to international guidelines. Global mortality was 74% but not significantly different between patients who benefited from therapeutic hypothermia compared to those who did not. All the patients who did not have an initial background activity (36/62; 58%) died. By contrast, initial background activity was present in 26/62 (42%) and among these patients, 16/26 (61%) survived. Electroencephalography demonstrated GPEDs patterns in 5 patients, all treated by therapeutic hypothermia and antiepileptic drugs. One of these survived and showed persistent background activity with responsiveness to benzodiazepine intravenous injection. Patients presenting suppressed background activity, even when treated by hypothermia, have a high probability of poor outcome. Thorough analysis of EEG patterns might help to identify patients with a better chance of survival. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    2017-01-01

    Importance Overdiagnosis of cancer—the identification of cancers that are unlikely to progress—is a source of discomfort and challenge for patients, physicians, and health care systems. A major cause of this discomfort is the inability to know prospectively with certainty which cancers are overdiagnosed. In thyroid cancer, as patients have begun to understand this concept, some individuals are independently deciding not to intervene, despite this practice not yet being widely accepted. Objective To describe the current experience of people who independently self-identify as having an overdiagnosed cancer and elect not to intervene. Design, Setting, and Participants In this qualitative study, semistructured interviews were conducted between July 1 and December 31, 2015, with 22 community-dwelling adults aged 21 to 75 years who had an incidentally identified thyroid finding that was known or suspected to be malignant and who questioned the intervention recommended by their physicians. Verbatim transcripts were analyzed using constant comparative analysis. Main Outcomes and Measures The experience of individuals who self-identify as having an overdiagnosed cancer and elect not to intervene. Results Of the 22 people interviewed (16 females and 6 males; mean age, 48.5 years), 18 had elected not to intervene on their thyroid finding and had been living with the decision for a mean of 39 months (median, 40 months; range, 1-88 months). Twelve of the 18 participants reported that they experienced significant anxiety about cancer progression, but had considered reasons for choosing nonintervention: understanding issues of precision in diagnostic testing and the varied behavior of cancer, surgical risks, medication use, and low risk of death from the cancer. Twelve participants described their decisions as met with nonreassuring, unsupportive responses. Medical professionals, friends, and internet discussion groups told them they were “being stupid,” “were wrong

    Full Text Available Abstract Background Noonan syndrome (NS and Noonan syndrome with multiple lentigines (NSML are autosomal dominant developmental disorders. NS and NSML are caused by abnormalities in genes that encode proteins related to the RAS-MAPK pathway, including PTPN11, RAF1, BRAF, and MAP2K. In this study, we diagnosed ten NS or NSML patients via targeted sequencing or whole exome sequencing (TS/WES. Methods TS/WES was performed to identify mutations in ten Chinese patients who exhibited the following manifestations: potential facial dysmorphisms, short stature, congenital heart defects, and developmental delay. Sanger sequencing was used to confirm the suspected pathological variants in the patients and their family members. Results TS/WES revealed three mutations in the PTPN11 gene, three mutations in RAF1 gene, and four mutations in BRAF gene in the NS and NSML patients who were previously diagnosed based on the abovementioned clinical features. All the identified mutations were determined to be de novo mutations. However, two patients who carried the same mutation in the RAF1 gene presented different clinical features. One patient with multiple lentigines was diagnosed with NSML, while the other patient without lentigines was diagnosed with NS. In addition, a patient who carried a hotspot mutation in the BRAF gene was diagnosed with NS instead of cardiofaciocutaneous syndrome (CFCS. Conclusions TS/WES has emerged as a useful tool for definitive diagnosis and accurate genetic counseling of atypical cases. In this study, we analyzed ten Chinese patients diagnosed with NS and related disorders and identified their correspondingPTPN11, RAF1, and BRAF mutations. Among the target genes, BRAF showed the same degree of correlation with NS incidence as that of PTPN11 or RAF1.

    To determine the prevalence of laryngopharyngeal (LP) abnormalities in hospitalized patients with dysphagia referred for flexible endoscopic evaluation of swallowing (FEES). Retrospective, blinded review by two otolaryngologists of 100 consecutive FEES studies performed and video-recorded by a speech-language pathologist (SLP). Two otolaryngologists reviewed videos of 100 consecutive FEES studies on hospitalized patients with dysphagia for the presence of abnormal LP findings. Sixty-one male and 38 female patients comprised the hospital dysphagia cohort. The mean age was 62. One subject could not be evaluated because of the severity of the retained secretions, leaving 99 subjects in the cohort. Seventy-six percent had been previously intubated, with a mean intubation duration of 13 days. The overall prevalence of abnormal LP findings was 79%. Forty-five percent of the patients presented with two or more findings, which included arytenoid edema (33%), granuloma (31%), vocal fold paresis (24%), mucosal lesions (17%), vocal fold bowing (14%), diffuse edema (11%), airway stenosis (3%), and ulcer (6%). There was a significant difference in LP findings between those individuals who had or had not been intubated. Hospitalized patients with dysphagia are at high risk for LP abnormalities, particularly if they have been intubated, and may benefit from either 1) an initial joint examination by the SLP and otolaryngologist or 2) an otolaryngologist's review of the recorded examination conducted by the SLP. Such otolaryngology involvement could identify airway stenosis patients at an earlier stage, initiate granuloma treatment sooner, enable earlier biopsy of unexpected lesions, and allow follow-up of mucosal and neuromuscular findings that do not respond to medical management.

    Regulations and guidelines regarding driving privileges of patients with epilepsy vary greatly worldwide. The aim of our study was twofold: firstly, to evaluate disobedient drivers in Greece and to elucidate their awareness of the law, emotional responses, and seizure profile and, secondly, to identify determinants of disobedience regarding driving among patients with epilepsy. All consecutive patients with epilepsy who visited the epilepsy outpatient clinic of two tertiary epilepsy centers were invited to participate in the study. One hundred ninety patients met our inclusion criteria. Fifty-two percent of our study population was aware of the driving restrictions. More than one out of three patients were disobedient (35.8%). Being a male was associated with a 6.07-fold increase in the odds of being disobedient (95% CI: 2.73-13.47, p important determinants of disobedience regarding driving among patients with epilepsy.

    This study identified the readiness factors that may create challenges in the use of telemedicine among patients in northern Louisiana with cancer. To identify these readiness factors, the team of investigators developed 19 survey questions that were provided to the patients or to their caregivers. The team collected responses from 147 respondents from rural and urban residential backgrounds. These responses were used to identify the individuals' readiness for utilising telemedicine through factor analysis, Cronbach's alpha reliability test, analysis of variance and ordinary least squares regression. The analysis results indicated that the favourable factor (positive readiness item) had a mean value of 3.47, whereas the unfavourable factor (negative readiness item) had a mean value of 2.76. Cronbach's alpha reliability test provided an alpha value of 0.79. Overall, our study indicated a positive attitude towards the use of telemedicine in northern Louisiana.

    Presently, the worldwide experience with robotic pancreatic surgery (RPS) is increasing although widespread adoption remains limited. In this study, we report our initial experience with RPS. This is a retrospective review of a single institution prospective database of 72 consecutive robotic hepatopancreatobiliary surgeries performed between 2013 and 2017. Of these, 30 patients who underwent RPS were included in this study of which 25 were performed by a single surgeon. The most common procedure was robotic distal pancreatectomy (RDP) which was performed in 20 patients. This included eight subtotal pancreatectomies, two extended pancreatecto-splenectomies (en bloc gastric resection) and 10 spleen-saving-RDP. Splenic preservation was successful in 10/11 attempted spleen-saving-RDP. Eight patients underwent pancreaticoduodenectomies (five hybrid with open reconstruction), one patient underwent a modified Puestow procedure and one enucleation of uncinate tumour. Four patients had extended resections including two RDP with gastric resection and two pancreaticoduodenectomies with vascular resection. There was one (3.3%) open conversion and seven (23.3%) major (>Grade II) morbidities. Overall, there were four (13.3%) clinically significant (Grade B) pancreatic fistulas of which three required percutaneous drainage. These occurred after three RDP and one robotic enucleation. There was one reoperation for port-site hernia and no 30-day/in-hospital mortalities. The median post-operative stay was 6.5 (range: 3-36) days and there were six (20%) 30-day readmissions.

    We aimed to evaluate whether mean platelet volume (MPV) and platelet distribution width (PDW) are helpful to identify complete thrombus resolution (CTR) after acute deep venous thrombosis (DVT). Patients who had first-time episode of acute proximal DVT were included in this retrospective study. 100 patients with DVT were divided into two groups according to absence (group 1; n = 68) or presence (group 2; n = 32) of CTR on doppler ultrasonography at month 6. There were no significant difference in admission MPV and PDW levels between group 1 and group 2. MPV (p = 0.03) and PDW (p venous thrombosis in DVT patients. Receiver operating characteristics analysis revealed that a 8.4 % decrease in admission MPV at month 6 provided 62 % sensitivity and 62 % specificity (AUC: 0.64) and a 15.4 % decrease in admission PDW at month 6 provided 87 % sensitivity and 94 % specificity (AUC: 0.89) for prediction of CTR in DVT patients. Percent change in admission MPV and PDW levels at month 6 may be used to identify the patients with CTR after a first episode of acute proximal DVT.

    PURPOSE We aimed to develop a simple standardized clinical score to stratify emergency ward patients with clinically suspected PE into groups with a high, intermediate, or low probability of PE, in order to improve and simplify the diagnostic approach. METHODS Analysis of a database of 1090 consecutive patients admitted to the emergency ward for suspected PE, in whom diagnosis of PE was ruled in or out by a standard diagnostic algorithm. Logistic regression was used to predict clinical parameters associated with PE. RESULTS 296 out of 1090 patients (27%) were found to have PE. The optimal estimate of clinical probability was based on eight variables: recent surgery, previous thromboembolic event, older age, hypocapnia, hypoxemia, tachycardia, band atelectasis or elevation of a hemidiaphragm on chest X-ray. A probability score was calculated by adding points assigned to these variables. A cut-off score of 4 best identified patients with low probability of PE. 486 patients (49%) had a low clinical probability of PE (score 9). CONCLUSION This clinical score, based on easily available and objective variables, provides a standardized assessment of the clinical probability of PE. Applying this score to emergency ward patients suspected of PE could allow a more efficient diagnostic process.

    To identify the top 10 unanswered research questions for primary care patient safety research. A modified nominal group technique. UK. Anyone with experience of primary care including: patients, carers and healthcare professionals. 341 patients and 86 healthcare professionals submitted questions. A top 10, and top 30, future research questions for primary care patient safety. 443 research questions were submitted by 341 patients and 86 healthcare professionals, through a national survey. After checking for relevance and rephrasing, a total of 173 questions were collated into themes. The themes were largely focused on communication, team and system working, interfaces across primary and secondary care, medication, self-management support and technology. The questions were then prioritised through a national survey, the top 30 questions were taken forward to the final prioritisation workshop. The top 10 research questions focused on the most vulnerable in society, holistic whole-person care, safer communication and coordination between care providers, work intensity, continuity of care, suicide risk, complex care at home and confidentiality. This study was the first national prioritisation exercise to identify patient and healthcare professional priorities for primary care patient safety research. The research priorities identified a range of important gaps in the existing evidence to inform everyday practice to address primary care patient safety. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    If variation in procedure times could be controlled or better predicted, the cost of surgeries could be reduced through improved scheduling of surgical resources. This study on the impact of similar consecutive cases on the turnover, surgical, and procedure times tests the perception that repeating the same manual tasks reduces the duration of these tasks. We hypothesize that when a fixed team works on similar consecutive cases the result will be shorter turnover and procedure duration as well as less variation as compared with the situation without a fixed team. Case-control study. St Franciscus Hospital, a large general teaching hospital in Rotterdam, the Netherlands. Two procedures, inguinal hernia repair and laparoscopic cholecystectomy, were selected and divided across a control group and a study group. Patients were randomly assigned to the study or control group. Preparation time, surgical time, procedure time, and turnover time. For inguinal hernia repair, we found a significantly lower preparation time and 10 minutes less procedure time in the study group, as compared with the control group. Variation in the study group was lower, as compared with the control group. For laparoscopic cholecystectomy, preparation time was significantly lower in the study group, as compared with the control group. For both procedures, there was a significant decrease in turnover time. Scheduling similar consecutive cases and performing with a fixed team results in lower turnover times and preparation times. The procedure time of the inguinal hernia repair decreased significantly and has practical scheduling implications. For more complex surgery, like laparoscopic cholecystectomy, there is no effect on procedure time.

    adult epilepsy clinic population: (a) to identify the frequency of seizure precipitants (triggering factors) and their relative frequency in those with psychiatric disorders, and in those in remission or with active epilepsy, differences in frequency with regard to gender, seizure duration, number of drugs taken; (b) to determine which precipitants patients most commonly report; and (c) to identify differences in the distribution of precipitants among generalized, temporal, and extratemporal epilepsies. Consecutive patients attending a tertiary-care epilepsy clinic were prospectively and an open personal interview to identify and characterize seizure precipitants. Information about the epilepsy and clinical characteristics of patients was collected during the interview and from medical records. Of 104 patients, 97% cited at least one precipitant. Stress, sleep deprivation, and fatigue were the most frequently reported precipitants. Patients with psychological comorbidities reported a greater percentage of seizures with seizure precipitants. Patients with idiopathic generalized epilepsy seemed to be more sensitive to seizures during awakening and sleep deprivation, patients with extratemporal epilepsy reported more frequent seizures during sleep. There were no differences in frequency or type of seizure precipitants with regard to gender, seizure duration or frequency, and the number of antiepileptic drugs taken. The findings may have implications for the better management of epilepsy by increasing a focus on nonpharmacological therapy. The implications of the findings for nosology and causation of epilepsy are also briefly discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

    Military and civilian data would suggest that hemostatic resuscitation results in improved outcomes for exsanguinating patients. However, identification of those patients who are at risk of significant hemorrhage is not clearly defined. We attempted to identify factors that would predict the need for massive transfusion (MT) in an Australasian trauma population, by comparing those trauma patients who did receive massive transfusion with those who did not. Between 1985 and 2010, 1,686 trauma patients receiving at least 1 U of packed red blood cells were identified from our prospectively maintained trauma registry. Demographic, physiologic, laboratory, injury, and outcome variables were reviewed. Univariate analysis determined significant factors between those who received MT and those who did not. A predictive multivariate logistic regression model with backward conditional stepwise elimination was used for MT risk. Statistical analysis was performed using SPSS PASW. MT patients had a higher pulse rate, lower Glasgow Coma Scale (GCS) score, lower systolic blood pressure, lower hemoglobin level, higher Injury Severity Score (ISS), higher international normalized ratio (INR), and longer stay. Initial logistic regression identified base deficit (BD), INR, and hemoperitoneum at laparotomy as independent predictive variables. After assigning cutoff points of BD being greater than 5 and an INR of 1.5 or greater, a further model was created. A BD greater than 5 and either INR of 1.5 or greater or hemoperitoneum was associated with 51 times increase in MT risk (odds ratio, 51.6; 95% confidence interval, 24.9-95.8). The area under the receiver operating characteristic curve for the model was 0.859. From this study, a combination of BD, INR, and hemoperitoneum has demonstrated good predictability for MT. This tool may assist in the determination of those patients who might benefit from hemostatic resuscitation. Prognostic study, level III.

    Preoperative localization studies are essential for patients who have undergone previous parathyroid operations. This is because the remaining parathyroid glands are more difficult to identify at operation because of increased scarring with loss of normal tissue planes and because the remaining abnormal parathyroid tissue is more likely to be situated in an ectopic position. This investigation concerns the accuracy of preoperative localization studies in 36 consecutive patients. All patients had symptoms and clinical and laboratory data diagnostic of primary (31 patients) or secondary (five patients) hyperparathyroidism. Ultrasonography was performed in all 36 patients; 18 (50%) were positive, 14 (39%) were negative, and four (11%) were false positive examinations. Eight of the negative study results occurred in patients with abnormal parathyroid glands situated in the mediastinum. Computerized tomography (CT) was performed in 25 patients. There was an equal number of positive (11; 44%) and negative (11; 44%) studies with three (12%) false positive test results. CT was helpful in identifying substernal lesions and other abnormal parathyroid glands situated in ectopic positions. Thallium chloride 201-technetium 99m pertechnetate scans were used in 22 patients. There was an equal number of positive (eight; 36%) and negative (eight; 36%) studies. Six patients (27%) had false positive scans. One or more of these noninvasive tests was positive in 27 of the 36 patients (75%). Highly selective venous catheterization for the measurement of immunoreactive parathyroid hormone concentrations localized the elusive parathyroid tumor in 12 of the 16 patients (75%) overall and in six of the nine patients (66%) whose tumors were not identified by other studies

    Full Text Available The peri - operative management of post - burn contractures of the neck is a challenge not only to the surgeon but also the anaesthesiologist. A proper co - ordination between them is needed for providing a hassle - free patient care. This is a prospective study done on 30 consecutive patients of post burn contractures of the neck to compare the surgeon’s assessment of the type and pattern of post - burn contracture of the neck and the anaesthesiologist’s assessment of the airway. T he association of this with the peri - operative management of patients was also studied. The data analysed was type of contracture , mento - sternal distance , and preoperative grading of the airway. The method of securing intra - operative airway was documented . A direct co - relation was noted between the type of contracture with the Mallampatti grading of the airway and the sterno - mental distance. All type III contractures required release before intubation. In conclusion , it is advisable for the surgeon to be w ell - versed with the anaesthesiologist’s assessment of the airway and the anaesthesiologist to aware of the types of neck contracture in order to properly plan and execute the peri - operative management of these patients.

    Patients can have an important role in reducing harm in primary-care settings. Learning from patient experience and feedback could improve patient safety. Evidence that captures patients' views of the various contributory factors to creating safe primary care is largely absent. The aim of this study was to address this evidence gap. Four focus groups and eight semistructured interviews were conducted with 34 patients and carers from south-east Australia. Participants were asked to describe their experiences of primary care. Audio recordings were transcribed verbatim and specific factors that contribute to safety incidents were identified in the analysis using the Yorkshire Contributory Factors Framework (YCFF). Other factors emerging from the data were also ascertained and added to the analytical framework. Thirteen factors that contribute to safety incidents in primary care were ascertained. Five unique factors for the primary-care setting were discovered in conjunction with eight factors present in the YCFF from hospital settings. The five unique primary care contributing factors to safety incidents represented a range of levels within the primary-care system from local working conditions to the upstream organisational level and the external policy context. The 13 factors included communication, access, patient factors, external policy context, dignity and respect, primary-secondary interface, continuity of care, task performance, task characteristics, time in the consultation, safety culture, team factors and the physical environment. Patient and carer feedback of this type could help primary-care professionals better understand and identify potential safety concerns and make appropriate service improvements. The comprehensive range of factors identified provides the groundwork for developing tools that systematically capture the multiple contributory factors to patient safety.

    Objective: This study was designed to determine the incidence of arterial pseudoaneurysm in patients presenting with postpartum hemorrhage (PPH), to analyze the angiographic characteristics of pseudoaneurysms that cause PPH, and to evaluate the effectiveness of pelvic arterial embolization for the treatment of this condition.Study designEighteen women with pelvic arterial pseudoaneurysm were retrieved from a series of 588 consecutive patients with PPH treated by arterial embolization. Clinical files, angiographic examinations, and procedure details were reviewed. Results: The incidence of pseudoaneurysm was 3.06 % (18/588; 95 % confidence interval (CI): 1.82-4.8 %). A total of 20 pseudoaneurysms were found; 15/20 (75 %) were located on the uterine arteries. Angiography revealed extravasation of contrast material from pseudoaneurysm indicating rupture in 9 of 18 (50 %) patients. Arterial embolization was performed using gelatin sponge alone in 12 of 18 (67 %) patients or in association with metallic coils in 5 of 18 (28 %) patients or n-butyl-2-cyanoacrylate in 1 of 18 (6 %) patients. Arterial embolization allowed controlling the bleeding in all patients after one or two embolization sessions in 17 of 18 (94 %) and 1 of 18 patients (6 %) respectively, without complications, obviating the need for further surgery. Conclusions: Pseudoaneurysm is rarely associated with PPH. Arterial embolization is an effective and safe procedure for the treatment of PPH due to uterine or vaginal artery pseudoaneurysm. Our results suggest that gelatin sponge is effective for the treatment of ruptured pseudoaneurysms, although we agree that our series does not contain sufficient material to allow drawing definitive conclusions with respect to the most effective embolic material.

    2018-04-01

    Full Text Available Purpose: Hysterectomy is the most common nonobstetrical surgery for women in the United States. Few investigations comparing hysterectomy surgical approaches include patient-centered outcomes. Methods: The study was performed at Henry Ford Health System (Detroit, MI between February 2015 and May 2015. A total of 1,038 eligible women — those 18 to 65 years of age and who had an electronic medical record-documented Current Procedural Terminology (CPT® code or an International Statistical Classification of Diseases, Ninth Edition (ICD-9 code of hysterectomy between December 2012 and December 2014 — were selected and recruited. A question guide was developed to investigate women’s experiences and feelings about the experience prior and subsequent to their hysterectomy. Analysis utilized the Framework Method. Study data were collected through structured focus groups with 24 posthysterectomy women in order to identify patient-centered outcomes to employ in a subsequent cohort study of hysterectomy surgical approaches. One pilot focus group and 5 additional focus groups were held. Qualitative data analysis, using data from coded transcripts of focus groups, was used to identify themes. Results: Focus groups with women who previously had a hysterectomy revealed their pre- and posthysterectomy perceptions. Responses were grouped into topics of pre- and postsurgical experiences, and information all women should know. Themes derived from responses: 1 decision-making; 2 the procedure (surgical experience; 3 recovery; 4 advice to past self; and 5 recommendations to other women. Conclusions: These analyzed data suggest a need for increased education and empowerment in the hysterectomy decision-making process, along with expanding information given for postoperative expectations and somatic changes that occur posthysterectomy. Findings about perceptions, beliefs, and attitudes of women having undergone hysterectomy could support health care providers

    Fragrance allergy and hand eczema are both common among dermatological patients. Fragrance mix (FM) and its constituents have a recognized relevance to exposure to fine fragrances and cosmetic products. Based on extensive chemical analysis and database search, a new selection of fragrances was established, including 14 known fragrance allergens present in products to which hand exposure would occur. A non-irritating patch-test concentration for some fragrances was established in 212 consecutive patients. 658 consecutive patients presenting with hand eczema were patch tested with the European standard series and the developed selection of fragrances. 67 (10.2%) of the 658 patients had a positive reaction to 1 or more of our selection of fragrance chemicals present in the new selection. The most common reactions to fragrances not included in the FM were to citral, Lyral (hydroxyisohexyl-3-cyclohexene carboxaldehyde) and oxidized l-limonene. A concomitant reaction to the FM identified potential fragrance allergy in less than (1/2) of these patients. Exposure assessment and a statistically significant association between a positive patch test to our selected fragrances and patients' history support the relevance of this selection of fragrances. Those with a positive reaction to our selected fragrances were significantly more likely to have 1 or more positive patch tests in the standard series. This observation is the basis for the hypothesis concerning cross-reactivity and the effect of simultaneous exposure. The study found that fragrance allergy could be a common problem in patients with eczema on the hands.

    2015-01-01

    Despite the use of administrative data to perform epidemiological and cost-effectiveness research on patients with hepatitis B or C virus (HBV, HCV), there are no data outside of the Veterans Health Administration validating whether International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) codes can accurately identify cirrhotic patients with HBV or HCV. The validation of such algorithms is necessary for future epidemiological studies. We evaluated the positive predictive value (PPV) of ICD-9-CM codes for identifying chronic HBV or HCV among cirrhotic patients within the University of Pennsylvania Health System, a large network that includes a tertiary care referral center, a community-based hospital, and multiple outpatient practices across southeastern Pennsylvania and southern New Jersey. We reviewed a random sample of 200 cirrhotic patients with ICD-9-CM codes for HCV and 150 cirrhotic patients with ICD-9-CM codes for HBV. The PPV of 1 inpatient or 2 outpatient HCV codes was 88.0% (168/191, 95% CI: 82.5-92.2%), while the PPV of 1 inpatient or 2 outpatient HBV codes was 81.3% (113/139, 95% CI: 73.8-87.4%). Several variations of the primary coding algorithm were evaluated to determine if different combinations of inpatient and/or outpatient ICD-9-CM codes could increase the PPV of the coding algorithm. ICD-9-CM codes can identify chronic HBV or HCV in cirrhotic patients with a high PPV and can be used in future epidemiologic studies to examine disease burden and the proper allocation of resources.

    2016-12-01

    The purpose of this study was to investigate fundus autofluorescence lifetimes in patients with choroideremia and to identify tissue-specific lifetime characteristics and potential prognostic markers. Autofluorescence lifetimes of the retina were measured in two spectral channels (498-560 nm and 560-720 nm) in patients with choroideremia and age-matched healthy controls. Furthermore, autofluorescence intensities and spectral-domain optical coherence tomography (OCT) data were acquired and compared to fundus autofluorescence lifetime data. Sixteen eyes from 8 patients with advanced choroideremia (mean ± SD age, 55 ± 13 years) were included in this study and compared with 10 age-matched healthy participants. Whereas fundus autofluorescence intensity measurement identified areas of remaining retinal pigment epithelium (RPE), autofluorescence lifetime maps identified areas with remaining photoreceptor layers in OCT but RPE atrophy. In these areas, mean (±SEM) lifetimes were 567 ± 59 ps in the short and 603 ± 49 ps in the long spectral channels (+98% and +88% compared to controls). In areas of combined RPE atrophy and loss of photoreceptors, autofluorescence lifetimes were significantly prolonged by 1116 ± 63 ps (+364%) in the short and by 915 ± 52 ps (+270%) in the long spectral channels compared with controls. Because autofluorescence lifetimes identify areas of remaining photoreceptors in the absence of RPE, this imaging modality may be useful to monitor disease progression in the natural course of disease and in context of potential future therapeutic interventions.

    Delirium is a common complication among elderly patients undergoing total joint arthroplasty (TJA). Its incidence has been reported from 4% to 53%. The Centers for Medicare and Medicaid Services consider delirium following TJA a "never-event." The purpose of this study is to evaluate a simple perioperative protocol used to identify delirium risk patients and prevent its incidence following TJA. Our group developed a protocol to identify and prevent delirium in patients undergoing TJA. All patients were screened and scored in the preoperative assessment, on criteria such as age, history of forgetfulness, history of agitation or visual hallucinations, history of falls, history of postoperative confusion, and inability to perform higher brain functions. Patients were scored on performance in a simple mental examination. The patients were classified as low, medium, or high risk. Patients who were identified as high risk were enrolled in a delirium avoidance protocol that minimized narcotics and emphasized nursing involvement and fluids administration. Five of 7659 (0.065%) consecutive TJA patients from 2010 to 2015 developed delirium. A total of 422 patients were identified as high risk. All 5 patients who suffered delirium were within the high risk group. No low or medium risk patients suffered a delirium complication. Three (0.039%) patients suffered drug-induced delirium, 1 (0.013%) had delirium related to alcohol withdrawal, and 1 (0.013%) had delirium after a systemic infection. This protocol is effective in identifying patients at high delirium risk and diminishing the incidence of this complication by utilizing a simple screening tool and perioperative protocol.

    Purpose: To compare measurements of the uterus and cervix obtained with magnetic resonance imaging (MRI) and transabdominal ultrasound to determine whether ultrasound can identify the brachytherapy target and be used to guide conformal brachytherapy planning and treatment for cervix cancer. Methods and Materials: Consecutive patients undergoing curative treatment with radiation therapy between January 2007 and March 2012 were included in the study. Intrauterine applicators were inserted into the uterine canal while patients were anesthetized. Images were obtained by MRI and transabdominal ultrasound in the longitudinal axis of the uterus with the applicator in treatment position. Measurements were taken at the anterior and posterior surface of the uterus at 2.0-cm intervals along the applicator, from the external os to the tip of the applicator. Data were analyzed using Bland Altman plots examining bias and 95% limits of agreement. Results: A total of 192 patients contributed 1668 measurements of the cervix and uterus. Mean (±SD) differences of measurements between imaging modalities at the anterior and posterior uterine surface ranged from 1.5 (±3.353) mm to 3.7 (±3.856) mm, and −1.46 (±3.308) mm to 0.47 (±3.502) mm, respectively. The mean differences were less than 3 mm in the cervix. The mean differences were less than 1.5 mm at all measurement points on the posterior surface. Conclusion: Differences in the measurements of the cervix and uterus obtained by MRI and ultrasound were within clinically acceptable limits. Transabdominal ultrasound can be substituted for MRI in defining the target volume for conformal brachytherapy treatment of cervix cancer

    Purpose: To compare measurements of the uterus and cervix obtained with magnetic resonance imaging (MRI) and transabdominal ultrasound to determine whether ultrasound can identify the brachytherapy target and be used to guide conformal brachytherapy planning and treatment for cervix cancer. Methods and Materials: Consecutive patients undergoing curative treatment with radiation therapy between January 2007 and March 2012 were included in the study. Intrauterine applicators were inserted into the uterine canal while patients were anesthetized. Images were obtained by MRI and transabdominal ultrasound in the longitudinal axis of the uterus with the applicator in treatment position. Measurements were taken at the anterior and posterior surface of the uterus at 2.0-cm intervals along the applicator, from the external os to the tip of the applicator.

    BACKGROUND Current surveillance guidelines for patients with long-standing ulcerative colitis (UC) recommend repeated colonoscopy with random biopsies, which is time-consuming, discomforting and expensive. A less invasive strategy is to identify neoplasia by analyzing biomarkers from the more accessible rectum to predict the need for a full colonoscopy. The goal of this pilot study is to evaluate whether optical markers of rectal mucosa derived from a novel optical technique – partial-wave spectroscopic microscopy (PWS) could identify UC patients with high-grade dysplasia (HGD) or cancer (CA) present anywhere in their colon. METHODS Banked frozen non-dysplastic mucosal rectal biopsies were used from 28 UC patients (15 without dysplasia and 13 with concurrent HGD or CA). The specimen slides were made using a touch prep method and underwent PWS analysis. We divided the patients into two groups: 13 as a training set and an independent 15 as a validation set. RESULTS We identified six optical markers, ranked by measuring the information gain with respect to the outcome of cancer. The most effective markers were selected by maximizing the cross validated training accuracy of a Naive Bayes classifier. The optimal classifier was applied to the validation data yielding 100% sensitivity and 75% specificity. CONCLUSIONS Our results indicate that the PWS-derived optical markers can accurately predict UC patients with HGD/CA through assessment of rectal epithelial cells. By aiming for a high sensitivity, our approach could potentially simplify the surveillance of UC patients and improve overall resource utilization by identifying patients with HGD/CA who should proceed with colonoscopy.

    BACKGROUND: Randomized trials comparing fibrinolysis with primary angioplasty for acute ST-elevation myocardial infarction have demonstrated a beneficial effect of primary angioplasty on the combined end point of death, reinfarction, and disabling stroke but not on all-cause death. Identifying...... a patient group with reduced mortality from an invasive strategy would be important for early triage. The Thrombolysis in Myocardial Infarction (TIMI) risk score is a simple validated integer score that makes it possible to identify high-risk patients on admission to hospital. We hypothesized that a high...... as high risk. There was a significant interaction between risk status and effect of primary angioplasty (P=0.008). In the low-risk group, there was no difference in mortality (primary angioplasty, 8.0%; fibrinolysis, 5.6%; P=0.11); in the high-risk group, there was a significant reduction in mortality...

    Full Text Available Background: Patients living with HIV/AIDS have complex medication regimens. Pharmacists within community pharmacy settings can have a role managing patients living with HIV/AIDS. Patients' perspectives surrounding implementation about community pharmacist-based services is needed as limited information is available. Objective: To identify medication-related needs of HIV-infected patients who receive prescriptions from a community pharmacy. To determine patient perspectives and knowledge of community pharmacist-based services. Methods: A qualitative research study involving in-depth, semi-structured interviews with patients was conducted. Inclusion criteria included: HIV positive men and women at least 18 years of age who receive care at a HIV clinic, currently take medication(s and use a community pharmacy for all prescription fills. Patients were recruited from one urban and one rural health center. Patients answered questions about their perceptions and knowledge about the role and value of pharmacy services and completed a demographic survey. The recordings of the interviews were transcribed verbatim and were analyzed using principles of Grounded Theory. Results: Twenty-nine interviews were conducted: 15 participants from the urban site and 14 from the rural site. Five main themes emerged including: patients experience ongoing and varying medication-related needs; patients desire a pharmacist who is caring, knowledgeable and integrated with health care providers; patients expect ready access to drug therapy; patients value an individualized patient encounter, and patients need to be informed that a pharmacist-service exists. Conclusion: Patients with HIV value individualized and personal encounters with pharmacists at time intervals that are convenient for the patient. Patients felt that a one-on-one encounter with a pharmacist would be most valuable when initiating or modifying medication therapy. These patient perspectives can be useful for

    Diabetic sensorimotor peripheral neuropathy (DSP) is the most prevalent complication in diabetes mellitus. Identifying DSP risk is essential for intervening early in the natural history of the disease. Small nerve fibers are affected earliest in the disease progression and evidence of this damage can be identified using in vivo corneal confocal microscopy (IVCCM). We applied IVCCM to a cohort of 40 patients with type 1 diabetes to identify their DSP risk profile. We measured standard IVCCM parameters including corneal nerve fiber length (CNFL), and performed nerve conduction studies and quantitative sensory testing. 40 patients (53% female), with a mean age of 48±14, BMI 28.1±5.8, and diabetes duration of 27±18 years were enrolled between March 2014 and June 2015. Mean IVCCM CNFL was 12.0±5.2 mm/mm 2 (normal ≥15 mm/mm 2 ). Ten patients (26%) without DSP were identified as being at risk of future DSP with mean CNFL 11.0±2.1 mm/mm 2 . Six patients (15%) were at low risk of future DSP with mean CNFL 19.0±4.6 mm/mm 2 , while 23 (59%) had established DSP with mean CNFL 10.5±4.5 mm/mm 2 . IVCCM can be used successfully to identify the risk profile for DSP in patients with type 1 diabetes. This methodology may prove useful to classify patients for DSP intervention clinical trials.

    This study assessed the ability of quantitative ultrasound (QUS) and digital X-ray radiogrammetry (DXR) to identify osteopenia and osteoporosis in patients with knee osteoarthritis (OA). One hundred and sixty-one patients with painful knee OA (81 men, 80 women; age 62.6{+-}9.2 years, range 40-82 years) were included in this cross-sectional study and underwent dual-energy X-ray absorptiometry (DXA) of both hips and the lumbar spine, QUS of the phalanges and calcanei of both hands and heels, and DXR using radiographs of both hands. Unpaired t-test, Mann-Whitney U test, ROC analysis and Spearman's rank correlation were used for comparisons and correlation of methods. Using DXA as the reference standard, we defined a low bone mineral density (BMD) as a T-score {<=}-1.0 at the lumbar spine or proximal femur. In contrast to phalangeal or calcaneal QUS, DXR was able to discriminate patients with a low BMD at the lumbar spine (p<0.0001) or hips (p<0.0001). ROC analysis showed that DXR had an acceptable predictive power in identifying OA patients a low hip BMD (sensitivity 70%, specificity 71%). Therefore, DXR used as a screening tool could help in identifying patients with knee OA for DXA. (orig.)

    The therapeutic use of thalidomide in patients with multiple myeloma is often complicated by the development of venous thromboembolism. The objective of the present study was to identify hypercoagulable states associated with development of venous thromboembolism in thalidomide-treated multiple myeloma patients. We screened 49 consecutive multiple myeloma patients treated with thalidomide at baseline for hypercoagulability. With a median follow-up of 11 months, 10 of 49 multiple myeloma patients developed a thrombotic episode. Laboratory assays revealed an underlying abnormality in nine of the 10 patients; hypercoagulable screenings were normal in 36 of the 39 patients who did not develop venous thromboembolism (P < 0.0001). Our retrospective study results suggest that the multiple myeloma patients with thromboembolic complications during treatment with thalidomide have a frequent concomitant underlying thrombophilic state.

    In order to resolve contradictions in addressing a soil moisture-precipitation feedback mechanism over West Africa and to clarify the impact of antecedent soil moisture on subsequent rainfall evolution, we first validated various data sets (SMOS satellite soil moisture observations, NOAH land surface model, TRMM rainfall, CMORPH rainfall and HadGEM climate models) with the Analyses Multidisciplinaires de la Mousson Africaine (AMMA) field campaign data. Based on this analysis, it was suggested that biases of data sets might cause contradictions in studying mechanisms. Thus, by taking into account uncertainties in data, it was found that the approach of consecutive dry days (i.e. a relative comparison of time-series) showed consistency across various data sets, while the direct comparison approach for soil moisture state and rainfall did not. Thus, it was discussed that it may be difficult to directly relate rain with soil moisture as the absolute value, however, it may be reasonable to compare a temporal progress of the variables. Based upon the results consistently showing a positive relationship between the consecutive dry days and rainfall, this study supports a negative feedback often neglected by climate model structure. This approach is less sensitive to interpretation errors arising from systematic errors in data sets, as this measures a temporal gradient of soil moisture state.

    Pediatricians of Japanese hospitals including not only residents but also attending physicians work long hours, and 8% work for >79 h per week. Most of them work consecutively for >or=32 h when they are on call. The aim of the present study was to evaluate the effect of long work hours on patient safety. The electronic databases MEDLINE and EMBASE to searched identify the English- and Japanese-language literature for studies on work hours, medical errors, patient safety, and malpractice for years 1966-2005. Studies that analyzed the relationship between physician work hours and outcomes directly related to patient safety were selected. Seven studies met the criteria. Four studies suggest that reduction of work hours has a favorable effect on patient safety indicators. In the other three studies no significant changes of the indicators were observed, but no report found that shorter work hours were harmful to patient safety. Decrease of physician work hours is not harmful but favorable to patient safety.

    This study identifies the incidence of hyponatraemia in cancer patients on an inpatient rehabilitation unit and examines the association between admission hyponatraemia and rehabilitation length of stay (LOS), functional outcome, and survival. After institutional review committee's approval, we retrospectively reviewed medical records of 295 consecutive patients who were admitted to this inpatient cancer rehabilitation unit between 27 January 2009 through 31 July 2010 in a tertiary cancer centre. The incidence of hyponatraemia in cancer patients admitted to our inpatient rehabilitation unit was 41.4%. Median rehabilitation LOS for patients with mild (Na 130-134 mEq/L) and moderate-severe (Na rehabilitation stay was not significantly different between three different patient groups. We concluded that large portion of patients who require acute inpatient rehabilitation presented with hyponatraemia, which is associated with prolonged rehabilitation LOS. Whether aggressive management of hyponatraemia will shorten rehabilitation stay needs further study. © 2013 John Wiley & Sons Ltd.

    The aim of this study was to measure the prevalence of potentially inappropriate medications (PIMs) by using the EU(7)-PIM list, STOPP (Screening Tool of Older Persons' potentially inappropriate Prescriptions) version 2 criteria and the new comprehensive protocol. This prospective study involved a sample of 276 consecutive elderly patients discharged from the university teaching hospital. Age, gender, diagnoses, medication history and medicines at discharge were recorded. The main outcome measure was the prevalence of PIMs according to each set of criteria: EU(7)-PIM list, STOPP version 2 criteria and comprehensive protocol. The median patient age (range) was 74 (65-92) years. The median number of prescribed medications was 7 (1-17). STOPP identified 393 PIMs affecting 190 patients (69%), EU(7)-PIM list identified 330 PIMs in 184 patients (66.7%) whilst the comprehensive protocol identified 134 PIMs in 102 patients (37%). STOPP version 2 criteria identified significantly more PIMs per patient than the other two protocols (p comprehensive protocol and was found as a more sensitive tool for PIM detection.

    Kidney recipients maintaining a prolonged allograft survival in the absence of immunosuppressive drugs and without evidence of rejection are supposed to be exceptional. The ERA-EDTA-DESCARTES working group together with Nantes University launched a European-wide survey to identify new patients, describe them and estimate their frequency for the first time. Seventeen coordinators distributed a questionnaire in 256 transplant centres and 28 countries in order to report as many 'operationally tolerant' patients (TOL; defined as having a serum creatinine <1.7 mg/dL and proteinuria <1 g/day or g/g creatinine despite at least 1 year without any immunosuppressive drug) and 'almost tolerant' patients (minimally immunosuppressed patients (MIS) receiving low-dose steroids) as possible. We reported their number and the total number of kidney transplants performed at each centre to calculate their frequency. One hundred and forty-seven questionnaires were returned and we identified 66 TOL (61 with complete data) and 34 MIS patients. Of the 61 TOL patients, 26 were previously described by the Nantes group and 35 new patients are presented here. Most of them were noncompliant patients. At data collection, 31/35 patients were alive and 22/31 still operationally tolerant. For the remaining 9/31, 2 were restarted on immunosuppressive drugs and 7 had rising creatinine of whom 3 resumed dialysis. Considering all patients, 10-year death-censored graft survival post-immunosuppression weaning reached 85% in TOL patients and 100% in MIS patients. With 218 913 kidney recipients surveyed, cumulative incidences of operational tolerance and almost tolerance were estimated at 3 and 1.5 per 10 000 kidney recipients, respectively. In kidney transplantation, operational tolerance and almost tolerance are infrequent findings associated with excellent long-term death-censored graft survival. © The Author 2016.

    This study aims at testing the hypothesis that the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) alternative model of personality disorder (AMPD) traits may be significantly associated with deficits on 2 different social cognition tasks, namely, the Reading the Mind in the Eyes Test and the Movie for the Assessment of Social Cognition, in a sample of consecutively admitted inpatients and outpatients. The sample was composed of 181 consecutively admitted participants (57.5% women; mean age = 38.58 years). Correlation coefficients and partial correlation coefficients were computed in order to assess the associations among social cognition tasks, DSM-5 AMPD traits, and dimensionally assessed DSM-5 Section II personality disorders. Specific maladaptive traits listed in the DSM-5 AMPD were significantly associated with Reading the Mind in the Eyes Test scores and Movie for the Assessment of Social Cognition scores, even when the effect of selected DSM-5 Section II personality disorders was controlled for. Our results support the relevance of studying social cognitive functioning in subjects suffering from personality disorders. Copyright © 2017 John Wiley & Sons, Ltd.

    Objective: To analyze and explore the value of 3 T high resolution magnetic resonance vessel wall imaging for identifying the activity of Takayasu arteritis. Methods: Twenty-six consecutive patients with Takayasu arteritis underwent 3.0 T high resolution MR vessel wall imaging on supraortic vessels (according to the classification of Lupi-Herrea, type I and III were included). Sixteen patients were in active phase and 10 in inactive phase based on the Kerr criteria. The MR vessel wall imaging appearances of Takayasu arteritis were compared between the active phase and inactive phase cases. Results: Wall thickening was demonstrated in all involved arteries. There were statistically significant differences between active phase and inactive phase cases in MR appearances including multi-ring thickening of vessel wall (75/80 and 18/50), arterial inner wail enhancement (50/80 and 19/50), obscurity of perivascular fat (55/80 and 18/50, X 2 =50.39, 7.41, 13.40, P<0.01). There was also a statistically significant difference in the thickness of carotid artery wall between the two groups [ (3.8 ± 0.2) mm vs (2.5 ± 0.8) mm]. Conclusion: 3 T high resolution MR vessel wall imaging is valuable for identifying the activity of Takayasu arteritis. (authors)

    There are an estimated one million patients with scrub typhus in the Asia-Pacific region. There are few reports describing the incidence of scrub typhus in Vietnam. Blood samples collected from 63 patients clinically diagnosed as having scrub typhus from July 2015 to September 2016 were subjected to genotyping of Orientia tsutsugamushi. Of these patients, 42 (67%) tested positive for O. tsutsugamushi, and the most common genotype was identified to be Karp (55%). Other genotypes, TA763, Gilliam type in Japan variant, and Kato were also found in 17%, 17% and 12% of patients, respectively. To better understand the epidemiological landscape of scrub typhus in Vietnam, a countrywide study is needed. LC110330-LC110333, LC110336-LC110351 and LC214804-LC214825. © The Author 2017.

    Full Text Available Background: Identifying COPD patients at high risk for mortality or healthcare utilization remains a challenge. A robust system for identifying high-risk COPD patients using Electronic Health Record (EHR data would empower targeting interventions aimed at ensuring guideline compliance and multimorbidity management. The purpose of this study was to empirically derive, validate, and characterize subgroups of COPD patients based on routinely collected clinical data widely available within the EHR.Methods: Cluster analysis was used in 5,006 patients with COPD at Intermountain to identify clusters based on a large collection of clinical variables. Recursive Partitioning (RP was then used to determine a preferred tree that assigned patients to clusters based on a parsimonious variable subset. The mortality, COPD exacerbations, and comorbidity profile of the identified groups were examined. The findings were validated in an independent Intermountain cohort and in external cohorts from the United States Veterans Affairs (VA and University of Chicago Medicine systems.Measurements and Main Results: The RP algorithm identified five LIVE Scores based on laboratory values: albumin, creatinine, chloride, potassium, and hemoglobin. The groups were characterized by increasing risk of mortality. The lowest risk, LIVE Score 5 had 8% 4-year mortality vs. 56% in the highest risk LIVE Score 1 (p < 0.001. These findings were validated in the VA cohort (n = 83,134, an expanded Intermountain cohort (n = 48,871 and in the University of Chicago system (n = 3,236. Higher mortality groups also had higher COPD exacerbation rates and comorbidity rates.Conclusions: In large clinical datasets across different organizations, the LIVE Score utilizes existing laboratory data for COPD patients, and may be used to stratify risk for mortality and COPD exacerbations.

    Echocardiographic criteria of right ventricular dysfunction (RVD) in acute pulmonary embolism (PE) differ among published studies. Assessment of RV systolic function remains difficult because of the RV's complex shape. We aimed to evaluate RV systolic function with TAD in patients (pts) with acute PE. TAD (QLAB, Philips Medical Imaging) was based on a tissue-tracking algorithm that is ultrasound beam angle independent for automated detection of tricuspid annular displacement. Prospective and observational study. All adults' pts who were diagnosed with PE from December 2008 to December 2009 at Princess Grace Hospital, Monaco were eligible for this study after exclusion of history of heart failure. We evaluated 36 consecutive pts with PE (18 male, mean age 62.7 years), which underwent echocardiography, plasma BNP titration during the first day after admission, and a second echocardiography obtained within 48 hours before discharge. TAD value were significantly lower in pts with abnormal RV function by echocardiogram (15.9 ± 0.3 vs. 12.7 ± 0.2 ; P = 0.026). Pts with a normal BNP (TAD (16.4 ± 0.2 vs. 11.2 ± 0.3 mm ; P TAD were significantly improved. There was no difference between TAD among pts with echocardiographic RVD at baseline vs. pts without RVD (14.9 ± 3.7 vs. 16.1 ± 2.9 mm ; P = 0.3). Four pts who deteriorated during short-term observation had substantially lower TAD values than those with uncomplicated courses (7.7 ± 0.4mm vs. 14.6 ± 0.2 mm ; P = 0.001). In conclusion, impaired TAD was associated with decreased RV systolic function in pts with acute PE. To identify the clinical meaning of decreased TAD, larger trials with longer follow-up periods are needed. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

    This study evaluates the risk factors and prognostic variables that affect survival of patients with gangrene of Fournier. The study retrospectively analyzed 90 consecutive patients with gangrene of Fournier treated in our institution between 1975 and 2008. We evaluated the average age, associated systemic diseases, and the source, time of evolution and extent of necrotizing fasciitis. The outcomes were assessed according to whether the patient survived or died. All patients had aggressive surgical debridement, and received parenteral antibiotic therapy. The mortality rate was 34.4%. The mean age was 63.0 years (range 33-95), a statistically significant difference was found between the age of the survivors (median age, 59.84 years) and those who died (median age, 70.20 years) (p = 0.001). Medical comorbidities were identified in 51 patients; the death rate was higher in patients who had any medical disease, especially those who suffered from cancer. Although diabetes mellitus was the most common associated pathology, it was not related to a statistically significant worst prognosis. The source of the infection was identified in 62 patients, who showed a higher mortality (p = 0.015), the mortality rate when a urological source is identified was 50%. Moreover, patients suffering from a more extensive necrotizing infection showed a worst prognosis. The gangrene of Fournier has a high mortality rate. Large series are required to study prognostic variables of this disease. The patient age, the presence of systemic risk factors, especially cancer, a urological source of infection and the extent of the disease have impact on the prognosis of Fournier's gangrene.

    Gynecomastia is a common finding in male subjects which incidence varies widely in the world population. In adolescents, it is frequently temporary but, if it becomes persistent, it generates considerable embarrassment, inducing the patients to seek surgical consultation. Even in patients with good body contour, gynecomastia creates even greater distress considering the special attention given by these subjects to their physical appearance. The authors present their experience in the treatment of gynecomastia comparing different body types of patients with the aim to investigate dissimilar expectations, needs and surgical outcomes thus optimizing the management of the pathological condition, achieving high levels of agreement and reducing unsatisfied patients arising from cosmetic surgery. Between January 2007 and January 2015, 312 selected patients have been treated surgically for gynecomastia. Patients were grouped according to their physical aspect: 97 were classified as high muscle mass body type (group A), 106 as normal (group B) and 109 as overweight patients (group C). All of them were adults ranging in age between 18 and 52 years. Follow-up ranged from 12 to 60 months. In all cases, an excision of the gland in the form of a subcutaneous mastectomy was performed; the most common surgical access was in the inferior part of the areola. No breast cancers were found at the histological examinations. Also, no skin or areola necrosis have been referred, and no recurrence of gynecomastia disorder has been reported. Six cases of seroma (limited to the fatty gynecomastia) and 3 cases of hematomas (requiring immediate surgical revision) were found. Although the patients in group B resulted more distressed by the disorder, higher levels of postoperative satisfaction were recorded in this group. The study demonstrates the importance of the different management of the same disorder according to the different patients' expectations, related to the different body type. Our

    To identify facial expressions occurring in patients at risk of deterioration in hospital wards. Prospective observational feasibility study. General ward patients in a London Community Hospital, United Kingdom. Thirty-four patients at risk of clinical deterioration. A 5-minute video (25 frames/s; 7,500 images) was recorded, encrypted, and subsequently analyzed for action units by a trained facial action coding system psychologist blinded to outcome. Action units of the upper face, head position, eyes position, lips and jaw position, and lower face were analyzed in conjunction with clinical measures collected within the National Early Warning Score. The most frequently detected action units were action unit 43 (73%) for upper face, action unit 51 (11.7%) for head position, action unit 62 (5.8%) for eyes position, action unit 25 (44.1%) for lips and jaw, and action unit 15 (67.6%) for lower face. The presence of certain combined face displays was increased in patients requiring admission to intensive care, namely, action units 43 + 15 + 25 (face display 1, p facial expressions can be identified in deteriorating general ward patients. This tool may potentially augment risk prediction of current scoring systems.

    Multiple scoring systems have been developed to predict outcomes in patients with upper gastrointestinal bleeding. We determined how well these and a newly established scoring model predict the need for therapeutic intervention, excluding transfusion, in Japanese patients with upper gastrointestinal bleeding. We reviewed data from 212 consecutive patients with upper gastrointestinal bleeding. Patients requiring endoscopic intervention, operation, or interventional radiology were allocated to the therapeutic intervention group. Firstly, we compared areas under the curve for the Glasgow-Blatchford, Clinical Rockall, and AIMS65 scores. Secondly, the scores and factors likely associated with upper gastrointestinal bleeding were analyzed with a logistic regression analysis to form a new scoring model. Thirdly, the new model and the existing model were investigated to evaluate their usefulness. Therapeutic intervention was required in 109 patients (51.4%). The Glasgow-Blatchford score was superior to both the Clinical Rockall and AIMS65 scores for predicting therapeutic intervention need (area under the curve, 0.75 [95% confidence interval, 0.69-0.81] vs 0.53 [0.46-0.61] and 0.52 [0.44-0.60], respectively).

    Farinatti, P, Paes, L, Harris, EA, Lopes, GO, and Borges, JP. A simple model to identify risk of sarcopenia and physical disability in HIV-infected patients. J Strength Cond Res 31(9): 2542-2551, 2017-Early detection of sarcopenia might help preventing muscle loss and disability in HIV-infected patients. This study proposed a model for estimating appendicular skeletal muscle mass (ASM) to calculate indices to identify "sarcopenia" (SA) and "risk for disability due to sarcopenia" (RSA) in patients with HIV. An equation to estimate ASM was developed in 56 patients (47.2 ± 6.9 years), with a cross-validation sample of 24 patients (48.1 ± 6.6 years). The model validity was determined by calculating, in both samples: (a) Concordance between actual vs. estimated ASM; (b) Correlations between actual/estimated ASM vs. peak torque (PT) and total work (TW) during isokinetic knee extension/flexion; (c) Agreement of patients classified with SA and RSA. The predictive equation was ASM (kg) = 7.77 (sex; F = 0/M = 1) + 0.26 (arm circumference; cm) + 0.38 (thigh circumference; cm) + 0.03 (Body Mass Index; kg·m) - 8.94 (R = 0.74; Radj = 0.72; SEE = 3.13 kg). Agreement between actual vs. estimated ASM was confirmed in validation (t = 0.081/p = 0.94; R = 0.86/p < 0.0001) and cross-validation (t = 0.12/p = 0.92; R = 0.87/p < 0.0001) samples. Regression characteristics in cross-validation sample (Radj = 0.80; SEE = 3.65) and PRESS (RPRESS = 0.69; SEEPRESS = 3.35) were compatible with the original model. Percent agreements for the classification of SA and RSA from indices calculated using actual and estimated ASM were of 87.5% and 77.2% (gamma correlations 0.72-1.0; p < 0.04) in validation, and 95.8% and 75.0% (gamma correlations 0.98-0.97; p < 0.001) in cross-validation sample, respectively. Correlations between actual/estimated ASM vs. PT (range 0.50-0.73, p ≤ 0.05) and TW (range 0.59-0.74, p ≤ 0.05) were similar in both samples. In conclusion, our model correctly estimated ASM

    Efficacy and safety of antibiotic prophylaxis (AP) for prevention of infective endocarditis (IE) in patients with predisposing cardiac condition (PCC) undergoing invasive procedures is still debated. We sought to assess the prevalence of PCC, the type of interventional procedures preceding the onset of symptoms, and the usefulness of AP in a large cohort of consecutive patients with definite IE. We examined 677 (median age 65.34 years; male 492 [73%]) consecutive patients with IE enrolled from July 2007 through 2010 into the Italian Registry of Infective Endocarditis. Predisposing cardiac condition was present in 341 patients (50%).Thirty-two patients (4.7%) underwent dental procedures. Of 20 patients with PCC undergoing dental procedure, 13 had assumed AP. Viridans group streptococci were isolated from blood cultures in 8 of 20 patients with PCC and prior dental procedure. Nondental procedures preceded IE in 139 patients (21%). They were significantly older and had more comordibities compared with patients undergoing dental procedures. Predisposing cardiac condition was identified in 91 patients. Perioperative antimicrobial prophylaxis was administered to 67 patients. Staphylococcus aureus was the most frequent causative agent. Cardiac surgery was necessary in 85 patients (20 with prior dental and 65 with nondental procedure). Surgical mortality (12% vs 0%, P = .03) and hospital mortality (23% vs 3%, P = .001) were significantly larger among patients with nondental procedures. In a large unselected cohort of patients with IE, the incidence of preceding dental procedures was minimal. The number of cases potentially preventable by means of AP was negligible. Nondental procedures were more frequent than dental procedures and were correlated with poorer prognosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Multidisciplinary rounds (MDRs) in the burn intensive care unit serve as an efficient means for clinicians to assess patient status and establish patient care priorities. Both tasks require significant cognitive work, the magnitude of which is relevant because increased cognitive work of task completion has been associated with increased error rates. We sought to quantify this workload during MDR using the National Aeronautics and Space Administration Task Load Index (NASA-TLX). Research staff at three academic regional referral burn centers administered the NASA-TLX to clinicians during MDR. Clinicians assessed their workload associated with 1) "Identify(ing) if the patient is better, same, or worse than yesterday" and 2) "Identify(ing) the most important objectives of care for the patient today." Data were collected on clinician type, years of experience, and hours of direct patient care. Surveys were administered to 116 total clinicians, 41 physicians, 25 nurses, 13 medical students, and 37 clinicians in other roles. Clinicians with less experience reported more cognitive work when completing both tasks (P NASA-TLX was an effective tool for collecting perceptions of cognitive workload associated with MDR. Perceived cognitive work varied by clinician type and experience level when completing two key tasks. Less experience was associated with increased perceived work, potentially increasing mental error rates, and increasing risk to patients. Creating tools or work processes to reduce cognitive work may improve clinician performance.

    Contact dermatitis of the scalp is common and might be caused by many chemicals including metals, ingredients of shampoos and conditioners, dyes, or other hair treatments. Eliciting a careful history and patch tests are necessary to identify the responsible allergen and prevent relapses. To identify allergens that may cause contact dermatitis of the scalp by reviewing patch test results. We reviewed the records of 1,015 patients referred for patch testing at the Dermatology Department of the University of Miami. A total of 226 patients (205 females and 21 males) with suspected scalp contact dermatitis were identified, and the patch test results and clinical data for those patients were analyzed. Most patients were referred for patch testing from a specialized hair clinic at our institution. The most common allergens in our study population were nickel (23.8%), cobalt (21.0%), balsam of Peru (18.2%), fragrance mix (14.4%), carba mix (11.6%), and propylene glycol (PG) (8.8%). The majority of patients were females aged 40-59 years, and scalp itching or burning were reported as the most common symptom. Frequent sources of allergens for metals include hair clasps, pins, and brushes, while frequent sources of allergens for preservatives, fragrance mix, and balsam of Peru include shampoos, conditioners, and hair gels. Frequent sources of allergens for PG include topical medications.

    2017-06-01

    Little is known about the causes of body dysmorphic disorder (BDD), but researchers have proposed a diathesis-stress model. This study uses a patient-centered approach to identify stressful events to which patients attribute the development of their BDD symptoms. An Internet-recruited sample of 165 adults with BDD participated. A large minority of participants attributed the development of their BDD to a triggering event. Bullying experiences were the most commonly described type of event. Additionally, most events were interpersonal and occurred during grade school or middle school. There were no differences in severity of psychosocial outcomes between participants who did or did not attribute their BDD to a specific triggering event. However, participants who specifically attributed their BDD development to a bullying experience had poorer psychosocial outcomes (i.e., perceived social support, depression severity, functional impairment, quality of life) compared to those who attributed their BDD development to another type of triggering event.

    Full Text Available Aim: The aim of this study is to characterize the clinical profile of patients with alcohol related seizures (ARS and to identify the prevalence of idiopathic generalized epilepsy (IGE in the same. Materials and Methods: 100 consecutive male patients presenting to a tertiary care center in South India with new onset ARS were analyzed with alcohol use disorders identification test (AUDIT score. All underwent 19 channel digital scalp electroencephalography (EEG and at least computed tomography (CT scan. Results: A total of 27 patients (27% who had cortical atrophy on CT had a mean duration of alcohol intake of 23.62 years compared with 14.55 years in patients with no cortical atrophy (P < 0.001. Twenty-two patients (22% had clustering in the current episode of whom 18 had cortical atrophy. Nearly, 88% patients had generalized tonic clonic seizures while 12% who had partial seizures underwent magnetic resonance imaging (MRI, which identified frontal focal cortical dysplasia in one. Mean lifetime duration of alcohol intake in patients presenting with seizures within 6 hours (6H-gp of intake of alcohol was significantly lower (P = 0.029. One patient in the 6H-gp with no withdrawal symptoms had EEG evidence for IGE and had a lower AUDIT score compared with the rest. Conclusion: CT evidence of cortical atrophy is related to the duration of alcohol intake and portends an increased risk for clustering. Partial seizures can be a presenting feature of ARS and those patients may benefit from MRI to identify underlying symptomatic localization related epilepsy (8.3% of partial seizures. IGE is more likely in patients presenting with ARS within first 6 hours especially if they do not have alcohol withdrawal symptoms and scalp EEG is helpful to identify this small subgroup (~1% who may require long-term anti-epileptic medication.

    As metoclopramide stimulates aldosterone secretion, we tested its usefulness in the assessment of lateralization of primary aldosteronism by adrenal vein sampling (AVS). Prospective within-patient study in consecutive patients undergoing AVS for primary aldosteronism subtyping. We compared the diagnostic accuracy of baseline and postmetoclopramide lateralization index and relative (to cortisol) aldosterone secretion indices (RASI) for each adrenal gland with aldosterone-producing adenoma (APA) determined by the four corners criteria as the reference diagnosis. We recruited 93 consecutive patients (mean age: 52 years; women 31%). Metoclopramide increased plasma aldosterone in the inferior vena cava and in both adrenal veins. The postmetoclopramide lateralization index was accurate in identifying APA, but did not increase diagnostic accuracy over baseline lateralization index, because the RASI increased similarly in both sides. Conversely, metoclopramide raised RASI to values more than 0.90 bilaterally in non-APA patients allowing accurate identification of factitious aldosterone suppression. In contrast, RASI was 0.90 or less in 48% contralateral to the tumor in APA patients. Regression analysis showed the APA patients with persistent suppression of RASI contralaterally showed a more florid primary aldosteronism phenotype. Metoclopramide does not enhance lateralization of aldosterone excess in APA, but consistently increased the value of RASI in non-APA cases, thus unmasking potentially misleading suppression of aldosterone. Postmetoclopramide RASI may therefore allow a more precise diagnosis when AVS can be achieved only unilaterally.

    Full Text Available The introduction of a national electronic health record system to the National Health Service (NHS has raised concerns about issues of data accuracy, security and confidentiality. The primary aim of this project was to identify the extent to which primary care patients will allow their local electronic record data to be shared on a national database. The secondary aim was to identify the extent of inaccuracies in the existing primary care records, which will be used to populate the new national Spine. Fifty consecutive attenders to one general practitioner were given a paper printout of their full primary care electronic health record. Participants were asked to highlight information which they would not want to be shared on the national electronic database of records, and information which they considered to be incorrect. There was a 62% response rate (31/50. Five of the 31 patients (16% identified information that they would not want to be shared on the national record system. The items they identified related almost entirely to matters of pregnancy, contraception, sexual health and mental health. Ten respondents (32% identified incorrect information in their records (some of these turned out to be correct on further investigation. The findings in relation to data sharing fit with the commonly held assumption that matters related to sensitive or embarrassing issues, which may affect how the patient will be treated by other individuals or institutions, are most likely to be censored by patients. Previous work on this has tended to ask hypothetical questions concerning data sharing rather than examine a real situation. A larger study of representative samples of patients in both primary and secondary care settings is needed to further investigate issues of data sharing and consent.

    Cross-sectional study. To describe readiness for change and barriers to physical activity in older adults and to contrast perceptions of physical therapists and patients using the Barriers to Being Active Quiz. Regular physical activity is vital to recovery after discharge from physical therapy. Physical therapists are positioned to support change in physical activity habits for those transitioning to home care. Understanding of readiness for change and barriers to physical activity could optimize recovery. Thirteen physical therapists enrolled in the study and invited patients who met the inclusion criteria to enroll (79 patients enrolled). The physical therapists provided the ICD-9 code, the physical therapist diagnosis, and completed the Barriers to Being Active Quiz as they perceived their patients would. The enrolled patients provided demographics and filled out the Satisfaction With Life Scale, the stages-of-change scale for physical activity, and the Barriers to Being Active Quiz. Patients were predominantly in the early stages of readiness for change. Both patients and physical therapists identified lack of willpower as the primary barrier to physical activity. Patients identified lack of willpower and social influence as critical barriers more often than physical therapists, whereas physical therapists identified fear of injury and lack of time more often than their patients did. Differences between physical therapists and their patients were noted for fear of injury (z = 2.66, P = .008) and lack of time (z = 3.46, P = .001). The stage of change for physical activity impacted perception of social influence (χ2 = 9.64, Pbarriers to physical activity may allow physical therapists to better tailor intervention strategies to impact physical activity behavior change.

    Background We sought to determine inter-rater reliability of the 2009 Appropriate Use Criteria (AUC) for radionuclide imaging (RNI) and whether physicians at various levels of training can effectively identify nuclear stress tests with inappropriate indications. Methods and Results Four hundred patients were randomly selected from a consecutive cohort of patients undergoing nuclear stress testing at an academic medical center. Raters with different levels of training (including cardiology attending physicians, cardiology fellows, internal medicine hospitalists, and internal medicine interns) classified individual nuclear stress tests using the 2009 AUC. Consensus classification by two cardiologists was considered the operational gold standard, and sensitivity and specificity of individual raters for identifying inappropriate tests was calculated. Inter-rater reliability of the AUC was assessed using Cohen’s kappa statistics for pairs of different raters. The mean age of patients was 61.5 years; 214 (54%) were female. The cardiologists rated 256 (64%) of 400 NSTs as appropriate, 68 (18%) as uncertain, 55 (14%) as inappropriate; 21 (5%) tests were unable to be classified. Inter-rater reliability for non-cardiologist raters was modest (unweighted Cohen’s kappa, 0.51, 95% confidence interval, 0.45 to 0.55). Sensitivity of individual raters for identifying inappropriate tests ranged from 47% to 82%, while specificity ranged from 85% to 97%. Conclusions Inter-rater reliability for the 2009 AUC for RNI is modest, and there is considerable variation in the ability of raters at different levels of training to identify inappropriate tests.

    In Denmark, a general impression of prolonged pretreatment delay for patients with head and neck cancer led to a nationwide study of time spans from symptom debut over first health care contact to start of treatment. Charts of consecutive new patients with squamous cell carcinoma of the pharynx...... and larynx, seen at the five Danish oncology centers in January-April 1992 and 2002, respectively, were reviewed. Of the 288 patients identified, definitive treatment was radiotherapy in 264 cases, surgery in one case. Twenty-three patients had neither surgery nor radiotherapy. Total time from first health...

    Gene expression profiling has been used extensively to characterize cancer, identify novel subtypes, and improve patient stratification. However, it has largely failed to identify transcriptional programs that differ between cancer and corresponding normal cells and has not been efficient in iden......-karyotype AML, which allowed for the generation of a highly prognostic survival signature. Collectively, our CvN method holds great potential as a tool for the analysis of gene expression profiles of cancer patients....

    Distress associated with attendance at a radiotherapy department was assessed in 80 consecutive patients. All patients were interviewed within 24 h of their first fraction of radiotherapy; 31 patients were also interviewed at the end of treatment. The problem identified at first interview as causing the most distress was worry about the effects of disease and its treatment upon the patient's family. At second interview the dominant complaint was of not being allowed to wash. Psychological problems, including anxiety and sleep disturbances, caused more overall distress than did physical symptoms. The method used in this study for eliciting information on the side-effects of therapy is straightforward and has yielded data that are provocative and suggest interesting avenues for further investigation.

    Fibromyalgia is a chronic widespread pain disorder in which, the neurogenic origin of the pain, featured by allodynia and hyperalgesia, results from an imbalance in the levels of neurotransmitters and consequently of the peripheral pro- and anti-inflammatory mediators. Whole body cryotherapy is a peculiar physical therapy known to relieve pain and inflammatory symptoms characteristics of rheumatic diseases, through the regulation of the cytokine expression. The aim of this study was to qualitatively evaluate the effects of cryotherapy on the clinical output of fibromyalgic patients. A total of 100 fibromyalgic patients (age range 17-70 years) were observed; 50 subjects were addressed to cryotherapy, while the second group (n = 50) did not underwent to the cryotherapic treatment. All subjects kept the prescribed pharmacological therapy during the study (analgesic and antioxidants). The referred health status pre- and post-observation was evaluated with the following scales: Visual Analogue Scale, Short Form-36, Global Health Status and Fatigue Severity Scale. Fibromyalgic patients treated with cryotherapy reported a more pronounced improvement of the quality of life, in comparison with the non-cryo treated fibromyalgic subjects, as indicated by the scores of the qualitative indexes and sub-indexes, that are widely recognized tools to assess the overall health status and the effect of the treatments. We speculate that this improvement is due to the known direct effect of cryotherapy on the balance between pro- and anti-inflammatory mediators having a recognized role in the modulation of pain.

    Full Text Available Abstract Background Structured education programmes are now established as an essential component to assist effective self-management of diabetes. In the case of Type 1 diabetes, the Dose Adjustment For Normal Eating (DAFNE programme improves both glycaemic control and quality of life. Traditionally delivered over five consecutive days, this format has been cited as a barrier to participation by some patients, such as those who work full-time. Some centres in the UK have organised structured education programmes to be delivered one day a week over several consecutive weeks. This type of format may add benefit by allowing more time in which to practice skills between sessions, but may suffer as a result of weaker peer support being generated compared to that formed over five consecutive days. Methods/design We aim to compare DAFNE delivered over five consecutive days (1 week course with DAFNE delivered one day a week over five weeks (5 week course in a randomised controlled trial. A total of 213 patients were randomised to attend either a 1 week or a 5 week course delivered in seven participating centres. Study outcomes (measured at baseline, 6 and 12 months post-course include HbA1c, weight, self-reported rates of severe hypoglycaemia, psychosocial measures of quality of life, and cost-effectiveness. Generalisability was optimised by recruiting patients from DAFNE waiting lists at each centre, and by mailing eligible patients from hospital clinic lists. The inclusion and exclusion criteria were identical to those used to recruit to a standard DAFNE course (e.g., HbA1c Discussion This trial has been designed to test the hypothesis that the benefits of delivering a structured education programme over 5 weeks are comparable to those observed after a 1 week course. The results of the trial and the qualitative sub-study will both inform the design and delivery of future DAFNE courses, and the development of structured education programmes in other

  4. How to Identify High-Risk APS Patients: Clinical Utility and Predictive Values of Validated Scores.

    Antiphospholipid syndrome (APS) is a clinical disorder characterised by thrombosis and/or pregnancy morbidity in the persistence of antiphospholipid (aPL) antibodies that are pathogenic and have pro-coagulant activities. Thrombosis in APS tends to recur and require prophylaxis; however, the stereotypical treatment for APS patients is inadequate and stratification of the thrombotic risks is important as aPL are prevalently observed in various diseases or elderly population. It is previously known that the multiple positive aPL or high titre aPL correlate to thrombotic events. To progress the stratification of thrombotic risks in APS patients and to quantitatively analyse those risks, antiphospholipid score (aPL-S) and the Global Anti-phospholipid Syndrome Score (GAPSS) were defined. These scores were raised from the large patient cohort data and either aPL profile classified in detail (aPL-S) or simplified aPL profile with classical thrombotic risk factors (GAPSS) was put into a scoring system. Both the aPL-S and GAPSS have shown a degree of accuracy in identifying high-risk APS patients, especially those at a high risk of thrombosis. However, there are several areas requiring improvement, or at least that clinicians should be aware of, before these instruments are applied in clinical practice. One such issue is standardisation of the aPL tests, including general testing of phosphatidylserine-dependent antiprothrombin antibodies (aPS/PT). Additionally, clinicians may need to be aware of the patient's medical history, particularly with respect to the incidence of SLE, which influences the cutoff value for identifying high-risk patients.

    To identify effective strategies for marketing pharmacist-provided medication therapy management (MTM) services to patients in a self-insured employer setting. Qualitative study. University of Pittsburgh during March through May 2008. 26 university employees taking at least one chronic medication. Three focus group sessions were conducted using a semistructured topic guide to facilitate the discussion. Employees' perceived medication-related needs, perceived benefits of pharmacist-provided MTM, potential barriers for employee participation in MTM, and effective strategies for marketing MTM. Participants reported concerns with timing of doses, medication costs, access, and ensuring adherence. Participants generally felt positively toward pharmacists; however, the level of reported patient contact with pharmacists varied among participants. Some participants questioned pharmacists' education and qualifications for this enhanced role in patient care. Perceived benefits of MTM noted by participants included the opportunity to obtain personalized information about their medications and the potential for improved communication among their health providers. Barriers to patient participation were out-of-pocket costs and lack of time for MTM visits. Participants suggested use of alternative words to describe MTM and marketing approaches that involve personal contact. Pharmacists should emphasize parts of MTM that patients feel are most beneficial (i.e., provision of a personal medication record) and use patient-friendly language to describe MTM when marketing their practice. Patients will need greater exposure to the concept of MTM and the pharmacists' role in order to correctly describe and assign value to this type of pharmacist patient care practice.

    Total blood homocysteine (Hcys) and folate levels have been investigated in association with cognitive dysfunction in healthy but not in multimorbid elderly patients. We hypothesized that total serum Hcys is an adequate marker to identify multimorbid elderly patients with cognitive dysfunction assessed by the Short Cognitive Performance Test (SKT) and Mini-Mental State Examination (MMSE). Cross-sectional study. The study center was an acute geriatric hospital. A total of 189 multimorbid elderly patients were recruited. Cognitive dysfunction was determined according to the SKT and MMSE. Biochemical parameters (Hcys, folate, vitamin B12, hemoglobin), nutritional status (BMI, Mini Nutritional Assessment, nutritional intake), and activities of daily living were assessed. According to the SKT, 25.4% of patients showed no cerebral cognitive dysfunction, 21.2% had suspected incipient cognitive dysfunction, 12.7% showed mild cognitive dysfunction, 9.0% had moderate cognitive dysfunction, and 31.7% of patients were demented. The median plasma Hcys value was elevated by approximately 20% in multimorbid elderly patients, independent of cognitive dysfunction. Serum folate and vitamin B12 concentrations were within normal ranges. We did not find significant differences in nutritional status, activities of daily living, numbers of diseases or medications, or selected biochemical parameters between the SKT groups. Elevated serum Hcys levels with normal plasma folate and vitamin B12 concentrations were observed in multimorbid elderly patients. The plasma Hcys level did not appear to be an important biological risk factor for cognitive dysfunction in multimorbid geriatric patients.

Little is known about the validity of the Short Physical Performance Battery (SPPB for identifying mobility limitations in patients with COPD. Objective: To determine the clinical validity of the SPPB summary score and its three components (standing balance, 4-meter gait speed, and five-repetition sit-to-stand for identifying mobility limitations in patients with COPD.Methods: This cross-sectional study included 137 patients with COPD, recruited from a hospital in Spain. Muscle strength tests and SPPB were measured; then, patients were surveyed for self-reported mobility limitations. The validity of SPPB scores was analyzed by developing receiver operating characteristic curves to analyze the sensitivity and specificity for identifying patients with mobility limitations; by examining group differences in SPPB scores across categories of mobility activities; and by correlating SPPB scores to strength tests.Results: Only the SPPB summary score and the five-repetition sit-to-stand components showed good discriminative capabilities; both showed areas under the receiver operating characteristic curves greater than 0.7. Patients with limitations had significantly lower SPPB scores than patients without limitations in nine different mobility activities. SPPB scores were moderately correlated with the quadriceps test (r>0.40, and less correlated with the handgrip test (r<0.30, which reinforced convergent and

    This study was undertaken to examine the role of interset stretching on the time course of acceleration portion AP and mean velocity profile during the concentric phase of 2 bench-press sets with a submaximal load (60% of the 1 repetition maximum). Twenty-five college students carried out, in 3 different days, 2 consecutive bench-press sets leading to failure, performing between sets static stretching, ballistic stretching, or no stretching. Acceleration portion and lifting velocity patterns of the concentric phase were not altered during the second set, regardless of the stretching treatment performed. However, when velocity was expressed in absolute terms, static stretching reduced significantly (p velocity during the second set compared to the first one. Therefore, if maintenance of a high absolute velocity over consecutive sets is important for training-related adaptations, static stretching should be avoided or replaced by ballistic stretching.

    Full Text Available Background: The treatment of Helicobacter pylori (HP infection in patients with diabetes mellitus with chronic gastroduodenal disorders is a substantial problem because of its high incidence. Aims: To compare between the effectiveness of triple and optimised consecutive regimens in anti-HP treatment in patients with type 2 diabetes mellitus with gastroduodenal disorders. Materials and methods: The study included 54 patients with diabetes mellitus and 64 healthy individuals (the control group aged 30–60 years. Gastroduodenal pathology was confirmed by gastroduodenoscopy; HР contamination was confirming using Marshall’s urease method or by finding bacterial antigen in excrements. We studied the dynamics of clinical manifestations using the GSRS scale and showed remission via endoscopy and the effectiveness of HР eradication. We also analysed the effects of anti-HР therapy regimens on the presence of small intestinal bacterial overgrowth syndrome (SIBOS in patients with diabetes mellitus. SIBOS was diagnosed via the respiratory hydrogen method. Results: The use of an optimised consecutive regimen resulted in HР eradication in 85.7% of patients with diabetes mellitus compared with a 65.3% eradication in patients on the triple therapy. Moreover, clinical improvement and endoscopy-confirmed remission were more frequently observed in patients on the optimised consecutive regimen. A statistically significant decrease in the number of patients with SIBOS was found only in patients who underwent the optimised consecutive therapy regimen. Conclusions: This study showed that the optimised consecutive therapy regimen was more effective than the triple therapy in HP eradication.

    Full Text Available Objective: The goal of this project was to develop a list of forenames and surnames of South Asian (SA women that could be used to identify SA breast cancer patients within the cancer registry. This list was compiled, evaluated, and validated to ensure comprehensiveness, accuracy, and applicability of SA names. Methods: This project was conducted by Canadian researchers who are immersed in conducting behavioral studies with SA women diagnosed with cancer in the province of British Columbia. Recruiting SA cancer patients for research can be a difficult task due to social and cultural factors. Methods used by other researchers to identify ethnicity related unique names were employed to filter surnames and forenames that were not common to this ethnic group. Co-author (Gurpreet Oshan of SA ethnicity rigorously identified and deleted multiple lists and redundant entries along with common English forenames which resulted in a list of 16,888 SA forenames. All co-authors of Indian ethnicity (Gurpreet Oshan, Savitri Singh-Carlson, Harajit Lail were involved in critiquing and manually reviewing the names list throughout this process. Comprehensive lists of SA surnames and women′s forenames were reviewed to identify those that were unique to SA ethnicity. Accuracy was ensured by constantly filtering the redundancy by using an Excel program which helped to illustrate the number of times each name was spelled in different ways. Results: The final lists included 9112 surnames and 16,888 forenames of SA ethnicity. On the basis of the surname linkage only, the sensitivity of the list was 76.6%, specificity was 62.9%, and the positive predictive value was 58.5%. On the basis of both the surname and forename linkage, the specificity of the list was 88.6%. These lists include variations in spelling forenames and surnames as well. Conclusions: The list of surnames and forenames can be useful tools to identify SA ethnic groups from large population database in

    Full Text Available Background: Lack of adherence to medication is a trigger of graft rejection in solid-organ transplant (SOT recipients. Objective: This exploratory study aimed to assess whether a biopsychosocial evaluation using the INTERMED instrument before transplantation could identify SOT recipients at risk of suboptimal post-transplantation adherence to immunosuppressant drugs. We hypothesized that complex patients (INTERMED>20 might have lower medication adherence than noncomplex patients (INTERMED≤20. Methods: Each patient eligible for transplantation at the University Hospital of Lausanne, Switzerland, has to undergo a pre-transplantation psychiatric evaluation. In this context the patient was asked to participate in our study. The INTERMED was completed pre-transplantation, and adherence to immunosuppressive medication was monitored post-transplantation by electronic monitors for 12 months. The main outcome measure was the implementation and persistence to two calcineurin inhibitors, cyclosporine and tacrolimus, according to the dichotomized INTERMED score (>20 or ≤20. Results: Among the 50 SOT recipients who completed the INTERMED, 32 entered the study. The complex (N=11 and noncomplex patients (N=21 were similar in terms of age, sex and transplanted organ. Implementation was 94.2% in noncomplex patients versus 87.8% in complex patients (non-significant p-value. Five patients were lost to follow-up: one was non-persistent, and four refused electronic monitoring. Of the four patients who refused monitoring, two were complex and withdrew early, and two were noncomplex and withdrew later in the study. Conclusion: Patients identified as complex pre-transplant by the INTERMED tended to deviate from their immunosuppressant regimen, but the findings were not statistically significant. Larger studies are needed to evaluate this association further, as well as the appropriateness of using a nonspecific biopsychosocial instrument such as INTERMED in highly

    Two hundred and thirty-one patients underwent dual-isotope myocardial imaging (rest thallium-201 followed by stress technetium-99m sestamibi). The feasibility of the procedure was excellent: camera scheduling flexibility was improved and the duration of the procedure was less than that of a classical stress-redistribution procedure. Interpretation of defects due to image attenuation was facilitated by the different attenuation properties of 201 Tl and 99m Tc-sestamibi in 11 of 19 patients. 201 Tl cross-over on 99m Tc was found to be 15% ± 3% with doses of 201 Tl and 99m Tc-sestamibi of 3 and 10 mCi, respectively, and 7% ± 2% with doses of 3 and 20 mCi. This protocol should preferentially be reserved for patients with a history of myocardial infarction and/or a basal left ventricular dysfunction, in whom assessment of myocardial viability is of major interest.

    In our recent study, of cases positive for epidermal growth factor receptor ( EGFR ) exon 19 deletions using comprehensive genomic profiling (CGP), 17/77 (22%) patients with prior standard of care (SOC) EGFR testing results available were previously negative for exon 19 deletion. Our aim was to compare the detection rates of CGP versus SOC testing for well-characterized sensitizing EGFR point mutations (pm) in our 6,832-patient cohort. DNA was extracted from 40 microns of formalin-fixed paraffin-embedded sections from 6,832 consecutive cases of non-small cell lung cancer (NSCLC) of various histologies (2012-2015). CGP was performed using a hybrid capture, adaptor ligation-based next-generation sequencing assay to a mean coverage depth of 576×. Genomic alterations (pm, small indels, copy number changes and rearrangements) involving EGFR were recorded for each case and compared with prior testing results if available. Overall, there were 482 instances of EGFR exon 21 L858R (359) and L861Q (20), exon 18 G719X (73) and exon 20 S768I (30) pm, of which 103 unique cases had prior EGFR testing results that were available for review. Of these 103 cases, CGP identified 22 patients (21%) with sensitizing EGFR pm that were not detected by SOC testing, including 9/75 (12%) patients with L858R, 4/7 (57%) patients with L861Q, 8/20 (40%) patients with G719X, and 4/7 (57%) patients with S768I pm (some patients had multiple EGFR pm). In cases with available clinical data, benefit from small molecule inhibitor therapy was observed. CGP, even when applied to low tumor purity clinical-grade specimens, can detect well-known EGFR pm in NSCLC patients that would otherwise not be detected by SOC testing. Taken together with EGFR exon 19 deletions, over 20% of patients who are positive for EGFR -activating mutations using CGP are previously negative by SOC EGFR mutation testing, suggesting that thousands of such patients per year in the U.S. alone could experience improved clinical

    Neuroblastoma (NBL) accounts for >7% of malignancies in patients younger than 15 years. Low- and intermediate-risk patients exhibit excellent or good prognosis after treatment, whereas for high-risk (HR) patients, the estimated 5-year survival rates is still <40%. The ability to stratify HR patients that will not respond to standard treatment strategies is critical for informed treatment decisions. In this study, we have generated a specific kinome gene signature, named Kinome-27, which is able to identify a subset of HR-NBL tumors, named ultra-HR NBL, with highly aggressive clinical behavior that not adequately respond to standard treatments. We have demonstrated that NBL cell lines expressing the same kinome signature of ultra-HR tumors (ultra-HR-like cell lines) may be selectively targeted by the use of two drugs [suberoylanilide hydroxamic acid (SAHA) and Radicicol], and that the synergic combination of these drugs is able to block the ultra-HR-like cells in G2/M phase of cell cycle. The use of our signature in clinical practice will allow identifying patients with negative outcome, which would benefit from new and more personalized treatments. Preclinical in vivo studies are needed to consolidate the SAHA and Radicicol treatment in ultra-HR NBL patients. © The Author 2017. Published by Oxford University Press. All rights reserved.

To identify among patients who had been previously defined as affected by T2DM those, in fact, affected by multigenerational diabetes; 2. After excluding patients carrying the most common MODY genes and mitochondrial mutations, we compared clinical features of remaining patients with those of patients with T2DM.Among 2,583 consecutive adult patients who had been defined as affected by T2DM, we looked for those with diabetes in ≥3 consecutive generations. All probands were screened for mutations in six MODY genes (HNF4A, GCK, HNF1A, PDX1, HNF1B and NeuroD1 and for the A3243G mitochondrial mutation. After excluding patients with mutations in one of such genes, we compared clinical features of the remaining 67 patients (2.6% of the whole initial sample affected by multigenerational "familial diabetes of the adulthood" (FDA and of their diabetic relatives (n = 63 to those with T2DM (n = 1,028 by generalized hierarchical linear models followed by pairwise comparisons.Age, age at diagnosis, proportion of hypertension (all p<0.001, and waist circumference (p<0.05 were lower in FDA than T2DM. Nonetheless, the two groups had similar age-adjusted incidence rate of all-cause mortality.Beside younger age at diagnosis, FDA patients show lower waist circumference and reduced proportion of hypertension as compared to those with T2DM; despite such reduced potential cardiovascular risk factors, FDA patients did not show a reduced mortality risk than patients with T2DM.

    Analysis of 327 consecutive cases at a pediatric referral hospital of Guatemala reveals that retinoblastoma accounts for 9.4% of all cancers and the estimated incidence is 7.0 cases/million children, higher than the United States or Europe. The number of familial cases is low, and there is a striking disparity in indigenous children due to late diagnosis, advanced disease, rapid progression and elevated mortality. Nine germline mutations in 18 patients were found; two known and five new mutations. Hypermethylation of RB1 was identified in 13% of the tumors. An early diagnosis program could identify cases at an earlier age and improve outcome of retinoblastoma in this diverse population. PMID:24814393

    The purpose of this study was to derive parameters that predict which high-energy blunt trauma patients should undergo computed tomography (CT) for detection of chest injury. This observational study prospectively included consecutive patients (≥16 years old) who underwent multidetector CT of the chest after a high-energy mechanism of blunt trauma in one trauma centre. We included 1,047 patients (median age, 37; 70% male), of whom 508 had chest injuries identified by CT. Using logistic regression, we identified nine predictors of chest injury presence on CT (age ≥55 years, abnormal chest physical examination, altered sensorium, abnormal thoracic spine physical examination, abnormal chest conventional radiography (CR), abnormal thoracic spine CR, abnormal pelvic CR or abdominal ultrasound, base excess <-3 mmol/l and haemoglobin <6 mmol/l). Of 855 patients with ≥1 positive predictors, 484 had injury on CT (95% of all 508 patients with injury). Of all 192 patients with no positive predictor, 24 (13%) had chest injury, of whom 4 (2%) had injuries that were considered clinically relevant. Omission of CT in patients without any positive predictor could reduce imaging frequency by 18%, while most clinically relevant chest injuries remain adequately detected. (orig.)

    In this study, quantitative real-time PCR (qPCR) was used to determine the amount of Fusarium oxysporum, an important replant disease pathogen in Pseudostellaria heterophylla rhizospheric soil. Moreover, HPLC was used to identify phenolic acids in root exudates then it was further to explore the effects of the phenolic acid allelochemicals on the growth of F. oxysporum f.sp. heterophylla. The amount of F. oxysporum increased significantly in P. heterophylla rhizosphere soil under a consecutive replant system as monitored through qPCR analysis. Furthermore, the growth of F. oxysporum f.sp. heterophylla mycelium was enhanced by root exudates with a maximum increase of 23.8%. In addition, the number of spores increased to a maximum of 12.5-fold. Some phenolic acids promoted the growth of F. oxysporum f.sp. heterophylla mycelium and spore production. Our study revealed that phenolic acids in the root secretion of P. heterophylla increased long with its development, which was closely related to changes in rhizospheric microorganisms. The population of pathogenic microorganisms such as F. oxysporum in the rhizosphere soil of P. heterophylla also sharply increased. Our results on plant-microbe communication will help to better clarify the cause of problems associated with P. heterophylla under consecutive monoculture treatment.

    To characterize the clinical features, aetiology and management of ophthalmic symptoms in adult patients with Parinaud syndrome. This is a retrospective, non-comparative observational case series. We reviewed 40 consecutive charts of adult patients with the clinical diagnosis of Parinaud syndrome at the Royal Adelaide Hospital Department of Ophthalmology in Adelaide, South Australia, between 1991 and 2016. Charts were reviewed for the following: (1) demographic information, (2) clinical presentation, (3) neuro-ophthalmology signs, (4) aetiology of Parinaud syndrome, and (5) management. Examination findings were collected at initial evaluation, throughout the course of follow-up, and at last follow-up. All the cases were assessed by one of the authors (JLC). The commonest presenting symptoms were diplopia (67.5%) and blurred vision (25%) followed by visual field defect (12.5%), ataxia (7.5%) and manifest squint (7.5%). The commonest presenting signs were vertical gaze palsy (100%), convergence-retraction nystagmus (87.5%) and light-near dissociation (65.0%). Only 65.0% patients had the classical triad of vertical gaze palsy, convergence-retraction nystagmus and light-near dissociation. Midbrain pathologies including haemorrhage (30.0%), infarction (20.0%) and tumour (15.0%) were the commonest aetiology. Pineal region tumours accounted for 30.0% of presentations. Symptoms were managed conservatively in 45% of cases with temporary occlusion, prisms or refractive correction, and observation in 42.5% of cases. Surgical intervention for refractory diplopia was required in 12.5% of cases, of which 80% reported symptom resolution following surgery. Our series highlights the variable clinical presentation of Parinaud syndrome. The classic triad of conjugate upgaze paralysis, convergence-retraction nystagmus and light-near dissociation was only present in 65% of cases. Pineal neoplasms remain an important aetiological consideration; however, primary midbrain pathology

    The aim of this study was to compare early dynamic imaging combined with delayed static imaging and single photon emission computed tomography (SPECT)/CT with delayed, planar, static imaging alone for sentinel node (SN) identification in melanoma patients. Three hundred and seven consecutive melanoma patients referred for SN biopsy (SNB) were examined using combined imaging. Secondary interpretation of only the delayed static images was subsequently performed. In 220 patients (72%), complete surgical and pathological information relating to the SNB was available. The number of SNs identified and number of patients with positive SNs were compared between the two interpretations of the imaging studies and, when available, related to pathology data. A slightly higher number of SNs (mean 0.12/patient) was identified when interpreting only delayed static images compared to combined imaging. In a direct patient-to-patient comparison, the number of SN(s) identified on the combined vs static images only showed moderate agreement (kappa value 0.56). In 38 patients (17%), positive SNs were identified by the combined procedure compared to 35 (16%) by static imaging only. Thus by static imaging only, tumour-positive SNs were not identified in 3 of 38 patients (8%). For SN identification in melanoma patients, dynamic imaging combined with delayed static imaging and SPECT/CT is superior to delayed static imaging only because the latter is more likely to fail to identify SNs containing metastases.

    Pain management in hospitalized patients remains a priority area for improvement; effective strategies for consensus development are needed to prioritize interventions. To identify challenges, barriers, and perspectives of healthcare providers in managing pain among hospitalized patients. Qualitative and quantitative group consensus using a brainstorming technique for quality improvement-the nominal group technique (NGT). One medical, 1 medical-surgical, and 1 surgical hospital unit at a large academic medical center. Nurses, resident physicians, patient care technicians, and unit clerks. Responses and ranking to the NGT question: "What causes uncontrolled pain in your unit?" Twenty-seven health workers generated a total of 94 ideas. The ideas perceived contributing to a suboptimal pain control were grouped as system factors (timeliness, n = 18 ideas; communication, n = 11; pain assessment, n = 8), human factors (knowledge and experience, n = 16; provider bias, n = 8; patient factors, n = 19), and interface of system and human factors (standardization, n = 14). Knowledge, timeliness, provider bias, and patient factors were the top ranked themes. Knowledge and timeliness are considered main priorities to improve pain control. NGT is an efficient tool for identifying general and context-specific priority areas for quality improvement; teams of healthcare providers should consider using NGT to address their own challenges and barriers.

    A maximal exercise test was performed in 54 patients with acute myocardial infarction (AMI) before discharge and in 49 age-matched control subjects. The long-term prognosis was assessed after an average follow-up of 7.6 years in AMI patients and 5.8 years in control subjects. The maximal work...... capacity and systolic blood pressure increase in AMI patients was 59% that of control subjects (p less than 0.001). Seventeen AMI patients had significant ST-segment shifts, 13 with ST depression and 4 with ST elevation. In AMI patients experiencing a cardiac death during follow-up the maximal work...... were of no significant value. In this study maximal work capacity turned out to be the best single exercise variable for identifying groups of AMI patients with very low and relative high risk of cardiac death. When all 3 exercise variables were combined, the predischarge maximal exercise test...

    Full Text Available The present study evaluated whether drug-induced sleep endoscopy (DISE helps identify the site of obstruction in patients with obstructive sleep apnoea (OSA. A total of 51 consecutive patients with polysomnography-confirmed OSA were enrolled in this prospective study. The presumed site of obstruction was determined according to history, otorhinolaryngologic examination, and polysomnography and a therapeutic plan designed before DISE. In 11 patients with severe OSA and/or previously failed continuous positive airway pressure (CPAP treatment, DISE with simultaneous CPAP was performed. Multilevel collapse was noted in 49 patients (96.1%. The most frequent multilevel collapse was palatal, oropharyngeal, and tongue base collapse (n=17, 33.3%, followed by palatal and oropharyngeal collapse (n=12, 23.5%. Pathology of the larynx (epiglottis was observed in 16 patients (31.4%. The laryngeal obstruction as a reason for intolerance of CPAP was observed in 3/11 (27.3% patients. After DISE, the surgical plan was changed in 31 patients (60.8%. The results indicate that DISE helps identify the site of obstruction in the upper airways in patients with OSA more accurately and that the larynx plays an important role in OSA.

    Optimal treatment strategy for retroperitoneal recurrence of testicular cancer involving the inferior vena cava (IVC) is uncertain. The purpose of this study was to validate the hypothesis that surgical resection, en-bloc with the involved segment of IVC and its subsequent reconstruction followed by chemotherapy, would yield better oncologic results than chemotherapy alone. Two consecutive series of patients with retroperitoneal recurrence of testicular cancer involving the IVC, treated with surgical resection plus chemotherapy (group A, n=14) or chemotherapy alone (group B, n=8) were retrospectively reviewed. The mean duration of follow-up was was 65 months (range=8-184). Operative mortality and morbidity in group A, response to chemotherapy in group B, disease-specific survival and quality adjusted life-years (QALY) for both groups, were primary end-points of the study. Postoperative mortality and morbidity (group A) were, respectively, nil and 14%. In group B, two patients (25%) fully responded to chemotherapy and remained free from disease progression. Disease-specific survival at 3 and 5 years was 81% and 54% in group A and 36% in group B both at 3 and 5 years, respectively (p=0.02). QALY was 3.92 in group A and 0.77 for both 3 and 5 years in group B, respectively, (p=0.031). En bloc resection of retroperitoneal recurrence of testicular tumors invading the IVC, followed by chemotherapy, allows a better survival rate compared to chemotherapy alone.

    To determine if the Consecutive Interpreting Approach enhances medical English communication skills of students in a Japanese medical university and to assess this method based on performance and student evaluations.  This is a three-phase study using a mixed-methods design, which starts with four language reproduction activities for 30 medical and 95 nursing students, followed by a quantitative analysis of perfect-match reproduction rates to assess changes over the duration of the study and qualitative error analysis of participants' language reproduction. The final stage included a scored course evaluation and free-form comments to evaluate this approach and to identify effective educational strategies to enhance medical English communication skills. Mean perfect-match reproduction rates of all participants over four reproduction activities differed statistically significantly (repeated measures ANOVA, pEnglish communication skills are enhanced using this approach. Participants expressed positive feedback regarding this instruction method. This approach may be effective to enhance the language skills of non-native English-speaking students seeking to practice medicine in English speaking countries.

    Outcome quality management requires the consecutive registration of defined variables. The aim was to identify relevant parameters in order to objectively assess the in-patient rehabilitation outcome. From February 2009 to June 2010 1253 patients (70.9 ± 7.0 years, 78.1% men) at 12 rehabilitation clinics were enrolled. Items concerning sociodemographic data, the impairment group (surgery, conservative/interventional treatment), cardiovascular risk factors, structural and functional parameters and subjective health were tested in respect of their measurability, sensitivity to change and their propensity to be influenced by rehabilitation. The majority of patients (61.1%) were referred for rehabilitation after cardiac surgery, 38.9% after conservative or interventional treatment for an acute coronary syndrome. Functionally relevant comorbidities were seen in 49.2% (diabetes mellitus, stroke, peripheral artery disease, chronic obstructive lung disease). In three key areas 13 parameters were identified as being sensitive to change and subject to modification by rehabilitation: cardiovascular risk factors (blood pressure, low-density lipoprotein cholesterol, triglycerides), exercise capacity (resting heart rate, maximal exercise capacity, maximal walking distance, heart failure, angina pectoris) and subjective health (IRES-24 (indicators of rehabilitation status): pain, somatic health, psychological well-being and depression as well as anxiety on the Hospital Anxiety and Depression Scale). The outcome of in-patient rehabilitation in elderly patients can be comprehensively assessed by the identification of appropriate key areas, that is, cardiovascular risk factors, exercise capacity and subjective health. This may well serve as a benchmark for internal and external quality management.

    The objective of this study was to evaluate the prevalence of blips and risk of virological failure (VF) among HIV-infected patients with sustained virological suppression (HIV-RNA ART. Newly diagnosed (2004-13) HIV-infected patients with sustained virological suppression on ART (minimum follow-up of 3 months) were identified. Risk of VF was evaluated according to different plasma HIV-RNA quantification values based on the limits of quantification/detection of current commercial assays (20 copies/mL). Kaplan-Meier and Cox proportional hazards models were used to compare the cumulative incidence of VF. A total of 565 newly diagnosed HIV-infected patients were identified: 453 started ART and 354 achieved virological suppression. Prevalence of blips (isolated HIV-RNA ranging from 50 to 200 copies/mL) and VF (HIV-RNA ≥50 copies/mL) was 22.7% and 8.8%, respectively (mean follow-up of 42 months). Multivariate analysis identified differences between HIV-RNA values as an independent predictor of VF (P = 0.008); risk of VF was higher for patients with blips [HR 2.500 (95% CI 0.524-11.926)] and for those with at least three consecutive detected, but not quantified, HIV-RNA determinations (HIV-RNA 200 copies/mL [33.7% at 24 and 60 months versus ART. HIV patients with blips and at least three consecutive detected, but not quantified, HIV-RNA determinations (<20 copies/mL) had a higher risk of VF. These findings highlight the relevance of maintaining HIV-RNA levels below the limits of quantification of current assays (<20 copies/mL). © The Author 2015.

    2017-08-01

    In order to study deformation characteristics of non-consecutive single jointed rock masses under impact loads, we used the cement mortar materials to make simulative jointed rock mass samples, and tested the samples under impact loads by the drop hammer. Through analyzing the time-history signal of the force and the displacement, first we find that the dynamic compression displacement of the jointed rock mass is significantly larger than that of the intact jointless rock mass, the compression displacement is positively correlated with the joint length and the impact height. Secondly, the vertical compressive displacement of the jointed rock mass is mainly due to the closure of opening joints under small impact loads. Finally, the peak intensity of the intact rock mass is larger than that of the non-consecutive jointed rock mass and negatively correlated with the joint length under the same impact energy.

    Endoscopic management of postcholecystectomy biliary leaks is widely accepted as the treatment of choice. However, refractory biliary leaks after a combination of biliary sphincterotomy and the placement of a large-bore (10F) plastic stent can occur, and the optimal rescue endotherapy for this situation is unclear. To compare the clinical effectiveness of the use of a fully covered self-expandable metal stent (FCSEMS) with the placement of multiple plastic stents (MPS) for the treatment of postcholecystectomy refractory biliary leaks. Prospective study. Two tertiary-care referral academic centers and one general district hospital. Forty consecutive patients with refractory biliary leaks who underwent endoscopic management. Temporary placement of MPS (n = 20) or FCSEMSs (n = 20). Clinical outcomes of endotherapy as well as the technical success, adverse events, need for reinterventions, and prognostic factors for clinical success. Endotherapy was possible in all patients. After endotherapy, closure of the leak was accomplished in 13 patients (65%) who received MPS and in 20 patients (100%) who received FCSEMSs (P = .004). The Kaplan-Meier (log-rank) leak-free survival analysis showed a statistically significant difference between the 2 patient populations (χ(2) [1] = 8.30; P stents (P = .024), a plastic stent diameter <20F (P = .006), and a high-grade biliary leak (P = .015) were shown to be significant predictors of treatment failure with MPS. The 7 patients in whom placement of MPS failed were retreated with FCSEMSs, resulting in closure of the leaks in all cases. Non-randomized design. In our series, the results of the temporary placement of FCSEMSs for postcholecystectomy refractory biliary leaks were superior to those from the use of MPS. A randomized study is needed to confirm our results before further recommendations. Copyright © 2015 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc. All rights reserved.

    During carotid endarterectomy (CEA), carotid cross-clamping is performed to allow for artery incision and plaque removal. A small subgroup of patients can tolerate carotid occlusion for only a few seconds, if at all, without presenting neurologic deficit. These patients are described as having ''cross-clamp intolerance.'' The purpose of this study was to demonstrate the safety of locoregional anesthesia in identifying patients with cross-clamp intolerance and factors associated with this condition. From August 2008 to May 2010, 115 consecutive patients were submitted to CEA under locoregional anesthesia at the Santa Casa de Belo Horizonte; the procedure was performed by the main author. Patients who showed intolerance to internal carotid artery (ICA) occlusion for intolerance. Among the 115 participating patients, 9.6% (11 patients) showed intolerance to ICA occlusion and developed deficits in intolerance). The factor that was associated with cross-clamp intolerance was the mean degree of contralateral carotid stenosis, which was 57.5% for those who presented intolerance and 27.8% for those who tolerated ICA occlusion. Locoregional anesthesia is a safe method for identifying patients with cross-clamp intolerance. Patients with cross-clamp intolerance present contralateral stenosis that is greater on average than patients who readily tolerate carotid artery occlusion. Copyright © 2016 Elsevier Inc.

    To investigate phenotypic variability in terms of best-corrected visual acuity (BCVA) in patients with Stargardt disease (STGD) and confirmed ABCA4 mutations. Entire coding region analysis of the ABCA4 gene by direct sequencing of seven patients with clinical findings of STGD seen in the Retina Clinics of Southampton Eye Unit between 2002 and 2011.Phenotypic variables recorded were BCVA, fluorescein angiographic appearance, electrophysiology, and visual fields. All patients had heterozygous amino acid-changing variants (missense mutations) in the ABCA4 gene. A splice sequence change was found in a 30-year-old patient with severly affected vision. Two novel sequence changes were identified: a missense mutation in a mildly affected 44-year-old patient and a frameshift mutation in a severly affected 34-year-old patient. The identified ABCA4 mutations were compatible with the resulting phenotypes in terms of BCVA. Higher BCVAs were recorded in patients with missense mutations. Sequence changes, predicted to have more deleterious effect on protein function, resulted in a more severe phenotype. This case series of STGD patients demonstrates novel genotype/phenotype correlations, which may be useful to counselling of patients. This information may prove useful in selection of candidates for clinical trials in ABCA4 disease.

    Minimally invasive approaches to partial nephrectomy have been rapidly gaining popularity but require advanced laparoscopic surgical skills. Renal hilar tumors, due to their anatomic location, pose additional technical challenges to the operating surgeon. We compared the outcomes of robot-assisted partial nephrectomy (RPN) for hilar and nonhilar tumors in our large multicenter contemporary series of patients. We retrospectively reviewed prospectively collected data on 446 consecutive patients who underwent RPN by renal surgeons experienced in minimally invasive techniques at four academic institutions from June 2006 to March 2010. Patients were stratified into two groups: those with hilar lesions and those with nonhilar lesions. Patient demographics, operative outcomes, and postoperative outcomes, including oncologic outcomes, were recorded. Forty-one patients (9%) had hilar renal masses; 405 patients (91%) had nonhilar masses. There was no statistical differences in patient demographics except for larger median tumor size in the hilar cohort (3.2 cm vs 2.6 cm; p=0.001). The only significant difference in operative outcomes was an increase in warm ischemia times for the hilar group versus the nonhilar group (26.3±7.4 min vs 19.6±10.0 min; p=<0.0001). There were no differences in postoperative outcomes; however, there was a trend for increased risk of malignancy and higher stage tumors in the hilar lesion group. Final pathologic margin status was similar in both groups. Only one patient in the nonhilar group had evidence of recurrence at 21 mo. The study was limited by the lack of standard anatomic classification of renal tumors and the potential influence of the surgeons' prior robotic experience. The data represent the largest series of its kind and strongly suggest that RPN is a safe, effective, and feasible option for the minimally invasive approach to renal hilar tumors with no increased risk of adverse outcomes compared with nonhilar tumors in the hands of

    The Ross procedure offers excellent short-term outcome but the long-term durability is under debate. Reinterventions and follow-up of 100 consecutive patients undergoing Ross Procedure at our centre (1993-2011) were analysed. Follow-up was available for 96 patients (97%) with a median duration of 5.3 (0.1-17.1) years. Median age of the patient cohort was 15.2 (0.04-58.4) years with 76 males. 93% had underlying congenital aortic stenosis. Root replacement technique was applied in all. The most common valved conduits used for reconstruction of the right ventricular outflow tract were homografts (66 patients) and bovine jugular vein (Contegra R ) graft (31 patients). Additional procedures included Ross-Konno procedure (14%), resection of subaortic stenosis/myectomy (11%) and reduction plasty of the ascending aorta (25%). One patient died within the first 30 days (1%). Late deaths occurred in 4 patients (4%) 0.5-4.5 years postoperatively: causes included pulmonary hypertension due to endocardial fibroelastosis (2), subarachnoid haemorrhage (1) and sudden cardiac death (1). Five-year survival was 93.6 (95% CI 88.1-99.1)%. Moderate or severe aortic (autograft) regurgitation needing reoperation occurred in 8 patients with a 5-year freedom from autograft reoperation of 98.5 (95.6-100)%. Five-year freedom from reintervention (surgery or catheter based) on the right ventricular outflow tract conduit was 91.5 (85.5-96.5)%. Univariate predictors of this reinterventions were smaller graft size (p = 0.03) and use of a Contegra R graft (p = 0.04). Ross procedure can be performed with low mortality and good survival in the long term. Most of the reinterventions are related to the neo-right ventricular outflow tract and may be partly attributed to the lack of growth. While the Ross Procedure remains an invaluable option for aortic valve disease in children, new solutions for the neo-pulmonary valve as well as for the less often occurring problems on the autograft are

    Full Text Available Introduction: To evaluate the use of multidimensional assessment based on the Fluegelman Index (FI to identify internal medicine patients who are likely to be difficult to discharge from the hospital. Materials and methods: Have been evaluated all patients admitted to the medical wards of the District General Hospital of Arezzo from September 1 to October 31, 2007. We collected data on age, sex, socioeconomic condition, cause of admission, comorbidity score preadmission functional status (Barthel Index, incontinence, feeding problems, length of hospitalization, condition at discharge, and type of discharge. The FI cut off for difficult discharge was > 17. Results: Of the 413 patients (mean age 80 + 11.37 years; percentage of women, 56.1% included in the study, 109 (26.39% had Flugelman Index > 17. These patients were significantly older than the patients with lower FIs (85 + 9.35 vs 78 + 11.58 years, p < 0.001, more likely to be admitted for pneumonia (22% vs. 4.9% of those with lower FIs; p < 0,001. They also had more comorbidity, loss of autonomy, cognitive impairment, social frailty, and nursing care needs. The subgroup with FIs>17 had significantly higher in-hospital mortality (30.28% vs 6.25%, p < 0.001, longer hospital stay (13 vs. 10 days, p < 0.05, and higher rates of discharge to nursing homes. Conclusions: Evaluation of internal medicine patients with the Flugelman Index may be helpful for identifying more critical patients likely to require longer hospitalization and to detect factors affecting the hospital stay. This information can be useful for more effective discharge planning.
