background: cytomegalovirus (cmv), a problematic virus in solid organ transplant recipients (sotr) such as liver, can worsen overall mortality and transplant outcome, so its prevention and treatment is a key of success in such patients. this study is aimed to compare the efficacy of ganciclovir (gcv) and valganciclovir (vgc) for prevention and treatment of infection with cmv. materials and meth...

  Background :The present study was conducted to establish the patterns and risk factors of surgical site infections in our institution between 2006 and 2011.   Methods: This was a retrospective cross-sectional study. The surgical site infection (SSI) was identified based on the presence of ICD-10-CM diagnostic code in hospital discharge records. By using a standardized data collection form pre...

The impact of dialysis modality on infection, especially early in the course of dialysis, has not been well studied. This study compared infection between hemodialysis (HD) and peritoneal dialysis (PD) from the start of dialysis and evaluated factors that have an impact on infection risk. In this observational cohort study, all incident dialysis patients (n = 181; HD 119 and PD 62) at a single ...

Endoscopic sphincterotomy (EST) is a treatment of choice for stone extraction and is now most frequently used. The study was to compare the efficacy of endoscopic papillary large balloon dilatation (EPLBD) and endoscopic sphincterotomy (EST) for common bile duct stone removal.

in this paper, a compound binomial risk model in the presence of a constant dividend barrier is studied. two types of individual claims, main claims and by-claims, are defined, where every by-claim is induced by the main claim randomly and may be delayed for one time period with a certain probability. in the evaluation of the moments of the present value of dividends, the interest rates are ass...

abstract background: the radiological impact of the use of phosphate fertilizers in soil is due to the internal irradiation of the lung by the alpha particles, short lived radon-thoron progeny and the external irradiation of the body by gamma rays emitted from radionuclides in situ. this paper describes the results of gamma spectrometric measurements of the concentration of the natural radionuc...

background: euroscore is a simple and rigorous risk stratification model and is, thus, commonly used in predicting the early and late outcomes of cardiac surgery across the world. we aimed to assess the discriminative power of the euroscore model to predict postoperative morbidity and total prolonged length of stay in hospital (los) and intensive care unit (icu) stay in an iranian group of card...
