Biopsy specimens of gastric and duodenal mucosa from 290 patients were examined histologically for metaplasia and Campylobacter pyloridis. Estimates of pH on samples of fasting gastric juice from 55 of the patients were performed, and mucosal biopsy specimens from 33 patients were also cultured for C pyloridis. Active duodenitis was seen in 34 duodenal biopsy specimens. Thirty (88%) of the pati...
Thirty nine children with recurrent abdominal pain aged between 5.5 and 12 years, underwent endoscopic duodenal biopsy to find out if there were any duodenal inflammatory changes, and if there was a relationship between duodenal inflammation and intestinal permeability to 51Cr-EDTA. Duodenal inflammation was graded by the duodenitis scale of Whitehead et al (grade 0, 1, 2, and 3). In 13 out of ...
BACKGROUND Recent guidelines have proposed that there is a correlation between tissue transglutaminase (tTG) antibody titers and degrees of duodenal biopsy, and that duodenal biopsy can be omitted in some patients with high levels of tTG antibody. Using data of registered patients in a gastrointestinal clinic we aimed to assess the correlation between tissue transglutaminase antibody with duode...
clinic because of gastric malignancy found on a periodic medical check−up. He had no specific symptoms or signs. Physical examination and routine labora− tory studies were normal. Esophagogas− troduodenoscopy revealed early gastric cancer (EGC) in the antrum, and there was an additional reddish ulcer scar with fold convergence in the anterior wall of the duodenal bulb. Unlike typical ulcer scar...
The number of gastrin-producing cells in biopsy specimens from the gastric and duodenal mucosae in 19 duodenal ulcer patients was quantitated using a morphometric method. The level of immunoreactive gastrin in a sample of fasting serum obtained at the time of the biopsy was measured by radioimmunoassay. The results show no significant difference when compared with those from a group of normal c...
background: northeast iran has one of the highest rates of esophageal cancer in the world which is mainly squamous cell carcinoma (e scc). celiac disease (cd) has been identified as a risk factor for escc. the aim of this study is to determine the prevalence of cd in gonbad at northeast iran and probable relation between celiac and escc. materials and methods: fourteen hundred inhabitants of no...
Changes in histamine storage in the oxyntic mucosa of duodenal ulcer patients and their reversal by vagotomy and the histamine H2-antagonist cimetidine supported the hypothesis that histamine could be a causal factor in peptic ulcer pathogenesis. The specificity of these findings was impaired by problems in biopsy taking, however, and in the preparative steps before measuring the actual histami...
Tissue sampling of primary duodenal lymphoma is essential for its histological diagnosis. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), which is frequently used for submucosal tumor (SMT)-like duodenal tumors, is adequate for cytological diagnosis, but not for histological diagnosis. Therefore, in the present study, a mucosal incision-assisted biopsy (MIAB) was performed in an ...
Aim. Atypical presentations of celiac disease (CD) have now been shown to be much more common than classical (typical) form. We evaluated the frequency of CD among adult patients with typical or atypical symptoms of CD. Materials and Methods. Patients referred to two outpatient gastroenterology clinics in Isfahan (IRAN) were categorized into those with typical or atypical symptoms of CD. IgA an...
