PRINCIPLES Percutaneous mitral balloon valvotomy is increasingly being carried out on patients with pure mitral stenosis, but discrepant results are still available at long-term follow-ups following percutaneous balloon and traditional surgical valvotomy. This research sought to systematically compare the efficacy and safety of mitral balloon and surgical valvotomy. METHODS A systematic liter...

purpose: libraries and information centers as information storage and retrieval systems can develop with the adoption of cybernetics rules. this paper discusses system dynamics, control, feedback, and other cybernetic concepts especially in information storage and retrieval systems. methodology: this study is a review intending to find what cybernetics and lis have in common especially in the f...

BACKGROUND Factors influencing success of sperm retrieval in azoospermic patients and outcome of ICSI were evaluated. METHODS AND RESULTS Uni- and multifactorial analysis were performed using logistic and stepwise analysis, following surgical sperm retrieval by percutaneous epididymal sperm aspiration (55 cycles) or testicular sperm extraction (142 cycles) in 52 and 123 patients with obstruct...

We assessed the rates of sperm retrieval and intracytoplasmic sperm injection outcomes, including the neonatal profile of infants conceived, in men with testicular failure. Three-hundred and sixty-five men with testicular failure who underwent micro-dissection testicular sperm extraction were included in this study. We compared their outcomes with 40 men with testicular failure who used donor s...

SETTING Men with postvasectomy infertility, evaluated and treated at centers with experience in vasectomy reversal or sperm retrieval and ICSI. PATIENT(S) Men with postvasectomy infertility, w...

This report summarizes the results of 64 percutaneous catheter drainage of abdominal abscesses and fluid collections in 56 patients. Aspiration and drainage was guided with computed tomography in 34 patients and with ultrasound in 30 patients. Success rate was 90%. Infected collections were successfully drained in 94% and noninfected collections in 72% . Partial success was achieved in two...

b-type natriuretic peptide (bnp) level is known to increase in patients with rheumatic mitral stenosis. in this systematic review, we aimed to discuss the possible association between plasma bnp level and the success rate of percutaneous transvenous mitral commissurotomy. pubmed and scopus databases were searched systematically, using the following key terms: “b-type natriuretic peptide” or “bn...

BACKGROUND Spillage of gallstones within the subcutaneous tissue during laparoscopic cholecystecomy may lead to considerable morbidity. METHODS We describe an abdominal wall abscess formation in a 50-year-old female that developed 24 months after a laparoscopic cholecystectomy. RESULTS Spilled gallstones at the umbilical port site went undetected. Subsequently, an umbilical port-site absces...

in recent decades, percutaneous endoscopic gastrostomy ( peg), has changed feeding and care of patients who can not feed orally. this outpatient procedure is done in most of the endoscopy wards and provides care, nutrition and medications for these patients outside the hospital. peg has rare complications and significantly reduces the cost of care and treatment .with invention of this procedure...
