Previous studies have reported some significant participation by gastric alcohol dehydrogenase (ADH) in alcohol metabolism, similar to that by hepatic ADH. However, the localization of this ADH in the stomach is not yet determined and there has been no study on the localization of ADH in the stomach of alcoholics before and after abstinence from alcohol. The aim of the present study was to reve...
HYPOTHESIS High-grade dysplasia (HGD) of the gastric epithelium is associated with high prevalence of invasive carcinoma, and distinction by endoscopic biopsy is difficult. DESIGN Cohort study, 1996 to 2003. SETTING Tertiary care center. PATIENTS Consecutive sample of 22 patients with initial diagnosis of gastric HGD by endoscopic biopsy. Biopsy specimens were separately reviewed by 3 exp...
BACKGROUND AND STUDY AIM Malignant change can occur in gastric ulcer but guideline recommendations for follow-endoscopy (FU-OGD) are conflicting. This study aims to determine rate of malignancy and need for follow-up for gastric ulcers. PATIENTS AND METHODS Patients with a first diagnosis of gastric ulcer between January 2012 and September 2013 were studied by analyzing endoscopic assessments...
Background. Scrub typhus results in vasculitis due to Orientia tsutsugamushi infection. The present study investigated whether O. tsutsugamushi infection is associated with gastric ulcer etiology and whether immunohistochemical staining of stomach tissue is useful to diagnose scrub typhus. Methods. A 78-year-old woman was hospitalized owing to general weakness that begun 4 days prior. As scrub ...
ach are extremely rare, accounting for less than 0.1% of primary gastric cancers [1]. The clinical behavior of primary gastric small cell carcinoma is as aggressive as that of small lung cancer [2]. Distal metastases are frequentlyobserved at initial presentation [3]. Small cell carcinomas proliferates mainly in the submucosal layer like a carcinoid tumor [1,4]; however, the tumor may have endo...
Background: Non-ulcerative dyspepsia is common clinical problem. There are controversies regarding the role of helicobacter pylori infection on gastric emptying in non-ulcerative dyspeptic patients, thus, the present study was designed. Materials and methods : Fifty patients with non-ulcerative dyspepsia referring to Endoscopy unit of Taleghani hospital were included. Initial data including dem...
Abstract Background and Objective: Recently, diabetes mellitus has been known as one of the main cause of upper gastrointestinal symptoms. Since a high prevalence of H. Pylori in diabetic patients has been reported, we aimed to evaluate the level of gastric juice Nitric Oxide (NO°), Oxidative Stress and Glycated Hemoglobin. Material and Methods: In case group, the participants were 60 diabe...
Background& Aims: Gastric adenocarcinoma has been considered as an infectious disease since 1994, when the Helicobacter pylori (H. pylori) infection categorized as a definite class I human carcinogen. H. pylori uses extensive numbers of virulence factors to overcome host defence mechanisms. One independent H. pylori factor that plays an important role in determining H.pylori pathogenesisis vacu...
Background and Purpose: Helicobacter pylori are a bacterial pathogen evolved to chronically colonize the gastric epithelium and causes gastritis, peptic ulcers, and even gastric malignancies in few infected humans. More recently, a pathogenicity island has been identified within the H. pylori genome that contains a cluster of genes, including cagE. The aim of the current study was to investig...
chewed 20 betel quids daily for 25 years, presented with a 3−day history of melena. Esophagogastroduodenoscopy (EGD) dis− closed an ulcerated tumor 3 cm in size in the antrum (l" Fig. 1). Biopsy of the tu− mor revealed acute and chronic inflam− mation. The patient quit chewing betel quids. Because of a strong suspicion of malignancy, EGD was repeated 5 days lat− er. It showed ulcers, from 0.5 t...
