We aimed to assess polyp detection rate (PDR) and to characterize demographic, clinical, and pathological features of colorectal polyps in an Iranian population.

A 25-year-old lady with severe rectorrhagia was presented with no history of constipation, diarrhea or abdominal pain. Colonoscopy revealed ulcers in the rectum, sigmoid colon, and terminal ileum. Crohn's pathologic features were detected in the terminal ileum. The bleeding was controlled via supportive care and IV corticosteroid. Recurrent LGIB was managed by prednisolone and azathioprine. The patient had an uneventful recovery. The clinicians should consider CD as a possible diagnosis in severe LGIB. Prednisolone and azathioprine efficiently control acute bleeding episodes and prevent the recurrence.

In the absence of integrated endoscopy and pathology databases, adenoma detection rate (ADR), as a validated quality indicator of screening colonoscopy, is generally difficult to obtain in practice. We aimed to measure the correlation of polyp-related indicators with ADR in order to identify the most accurate surrogate(s) of ADR in routine practice. METHODS We retrospectively reviewed the endoscopic and histopathological findings of patients who underwent colonoscopy at a tertiary gastrointestinal clinic. The overall ADR and advanced-ADR were calculated using patient-level data. The Pearson's correlation coefficient (r) was applied to measure the strength of the correlation between the quality metrics obtained by endoscopists. RESULTS A total of 713 asymptomatic adults aged 50 and older who underwent their first-time screening colonoscopy were included in this study. The ADR and advanced-ADR...

This study was done to determine the clopidogrel effect in preventing reduced LV function in patients with STEMI. In this study, 144 patients with STEMI admitted to the Isfahan University of Medical Sciences hospitals were followed in two groups for one month. The case group received Clopidogrel, 300 mg, on admission and then, 75 mg daily, while the control group received routine therapy for STEMI without Clopidogrel. Left ventricular ejection fraction (LVEF) on the 4(th) day and one month after STEMI was measured by echocardiography. The results of LVEF were compared within and between groups. The mean LVEF in the case group on the 4(th) day and one month after STEMI were 45.92 and 52.15%, respectively (P<0.001). The mean LVEF in the control group on 4(th) day and one month after STEMI were 44.72 and 42.71%, respectively. We sugges...

We aimed to assess polyp detection rate (PDR) and to characterize demographic, clinical, and pathological features of colorectal polyps in an Iranian population. METHODS We retrospectively analyzed the data from 5427 colonoscopies performed during 2007-2012 at Masoud Clinic, the main endoscopy center associated with Sasan Alborz Biomedical Research Center, in Tehran, Iran. RESULTS Our sample included 2928 (54%) women and 2499 (46%) men, with the mean age of 48.3 years (SD=16.1). The most common reasons for colonoscopy included screening in 25.0%, and gastrointestinal bleeding in 15.2%. Cecal intubation was successful in 86% of patients. The quality of bowel preparation was fair to excellent in 78.1% (n=4235) of colonoscopies. Overall PDR was 42.0% (95% CI: 40.6-43.3). The PDR in men (51.1%, 95% CI: 49.1-53.1) was significantly higher...

Researchers showed significant relations between TIMI with angiography scores in patients with UA/NSTEMI. We studied this relation in patients with STEMI. We studied CCU patients with STEMI hospitalized in several hospitals of Isfahan, Iran from September 2007 to June 2008. Sampling method of 240 patients was random and simple. Exclusion criteria were incomplete history, nonspecific electrocardiogram changes, left bundle branch block and not accomplished angiography or accomplished angiography after 2 months of STEMI. Questionnaire indices collected on the basis of TIMI (0-14 points). Echocardiography and angiography were done and then, we used Gensini (0-400 points) to review films of angiography. Spearman's rank test and Pearson correlation coefficient were used to study the relation betwee...

We aimed to calculate the adenoma detection rates (ADR), and assess the quality of colonoscopies in an opportunistic screening colonoscopy program in Iran. Methods: All the colonoscopy and pathology reports of asymptomatic adults over age 50 who underwent screening colonoscopy between June 2007 and March 2013 were reviewed. The colonoscopy quality indicators including ADR were calculated, and patient factors associated with the adenoma detection were determined.
