Compression of Histopathology, Culture and Rapid Urease Test in Diagnosis of Helicobacter Pylori in Gastric Biopsy Specimens

Abstract Background and Objective: Helicobacter pylori (H. Pylori) infection is related to chronic gastritis, peptic ulcer, duodenal ulcer and gastric cancer. Thus, identification and treatment of the infection have a considerable importance. The aim of this study was to compare three methods of Histopathology, Culture and Rapid Urease test (RUT) in identification of H. Pylori in gastric bio...

Whipple's disease with esophageal and colonic involvement: endoscopic and histopathologic findings.

هم خوانی یافته‌های آندوسکوپی و هیستوپاتولوژیکی بیوپسی معده در بیماران ارجاعی به بیمارستان فیروزگر تهران (1396-1395)

Background: Stomach is a common location for benign and malignant lesions in the digestive system from inflammation to cancer. Therefore, recognition and diagnosis in the endoscopic stage and its confirmation in a pathological examination will be critical. Objective: The aim of this study was to investigate the correlation between endoscopic and histopathological findings in the patients with ...

Accuracy of identification of tissue types in endoscopic esophageal mucosal biopsies used for molecular biology studies

OBJECTIVES To determine if histopathologic assessment of esophageal biopsies harvested for research study is justified due to the heterogeneity of tissues in the esophagus, and the consequent histopathologic mis-matches with the clinical histopathology of biopsies taken at the same level. METHODS Since 2004, patients undergoing upper endoscopy for a variety of clinical conditions were invited...

Detection of Bronchial Neoplasia in Uranium Miners by Autofluorescence Endoscopy (SAFE-1000)

The increase in the detection rate for premalignant changes of bronchial epithelium was studied in 56 symptom-free volunteers from the risk group of Czech uranium miners (mean age 50.69 years, mean WLM 21.06 (1 Working Level Month is equal to the absorption of latent energy of 2.08 x 10(-5) J/m(3) in one month, i.e. 170 working hours)) by the additional employment of the System of Autofluoresce...
