Abstract Background and study aims In gastrointestinal endoscopy, biopsies must transit through the accessory channel cap, presenting an opportunity for loss of tissue. We sought to determine incidence specimen retention in or cap identify procedure characteristics associated with retention. Patients methods After completion standard endoscopic procedures which were obtained, biopsy inspected, ...

Purpose The outcome of the present study is to determine variables available at time diagnosis able predict disease reclassification in prostate cancer (PCa) patients on active surveillance (AS). Materials and methods From January 2014 December 2018, 114 consecutive low-risk PCa were enrolled AS protocol according inclusion criteria: PSA ≤ 10 ng/ml, Gleason score (GS) 6 or International Society...

CONTEXT The current standard for diagnosing prostate cancer in men at risk relies on a transrectal ultrasound-guided biopsy test that is blind to the location of the cancer. To increase the accuracy of this diagnostic pathway, a software-based magnetic resonance imaging-ultrasound (MRI-US) fusion targeted biopsy approach has been proposed. OBJECTIVE Our main objective was to compare the detec...

brain injury has a multiple pathophysiology for which there is no definite treatment. in this regard, tissue engineering is one of the probable strategies for repair of damaged tissue. but creating a proper model for testing the engineered products faced some difficulties, specially, when we want to evaluate the effects of a product on the volume of injury. the current brain injury methods coul...

introduction: lasers have made tremendous progress in the field of dentistry and have turned out to be crucial in oral surgery as collateral approach for soft tissue surgery. this rapid progress can be attributed to the fact that lasers allow efficient execution of soft tissue procedures with excellent hemostasis and field visibility. when matched to scalpel, electrocautery or high frequency de...

nephrotic syndrome is the commonest glomerular disease. typical symptoms could be proteinuria, low serum albumin and oedema. the mechanism of proteinuria in nephrotic syndrome is a defective glomerular filtration barrier. renal biopsy is the gold standard for diagnosis of nephrotic syndrome currently which is invasive and based on histopathological features, therefore it seems to be necessary to...

background: coeliac disease (cd) is characterized by malabsorption resulting from inflammatory injury to the mucosa of the small intestine by an inappropriate immune response to dietary gluten proteins. the aim of this study was to assess the prevalence of cd in our endoscopy unit by taking routine duodenal biopsies during upper gi endoscopy. materials andmethods: nine hundred and thirteen pati...

conclusion this study demonstrated that repeating the tfna procedure in pulmonary lesions improves the diagnostic yield without an increase in the rate of pneumothorax. objectives we aimed to investigate whether repeating ct-guided transthoracic fine needle aspiration (tfna) increases diagnostic yield and complication rate. patients and methods patients underwent tfna and the final diagnoses ac...

background: the normal prostate-specific antigen (psa) level in patients with urethral catheterization is a controversy. we designed this study to investigate the effect of nontraumatic urethral catheterization without urinary retention on serum psa. materials and methods: seventy patients scheduled for urethral catheterization before elective surgeries were randomly selected and included in th...
