ABSTRACT Attention to high prevalence of inflammatory disease of upper gastrointestinal system and determination of Helicobacter pylori, “a great importance etiology of gastric disorders”, this study was performed for rapid diagnostic evaluation of Helicobacter pylori. This observational & cross-sectional study was performed in 100 cases who suffered from upper gastrointestinal symptoms. By an ...
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...
background and aims: helicobacter pylori (h. pylori) is the microorganism that infects nearly half of word's population. there are several invasive and non-invasive methods for diagnosis of infection. the main objective of this study was to evaluate antigen of h. pylori in feces with h. pylori stool antigen (hpsa) test and comparison with rapid urease test (rut) in the patients suspected t...
To determine the diagnostic accuracy of the one-minute ultra-rapid urease test for diagnosing Helicobacter pylori infection, two biopsies were taken from both the gastric corpus and antrum from 1000 patients undergoing upper gastrointestinal endoscopy. All the biopsies were subjected to the one-minute ultra-rapid urease test before imprint smears were prepared from them. Thereafter, the biopsie...
The aim of the study was to evaluate the suitability of a modified one minute rapid urease test (one day rapid urease test) as a low cost H. pylori detection method. A sample of 205 patients clinically suspected of having H. pylori infection was tested. One day rapid urease test and histology based H. pylori tests (the gold standard) were performed on endoscopic antral biopsies. There were 6 tr...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
background: helicobacter pylori (h.pylori) infection causes multiple upper gastrointestinal diseases but optimal therapeutic regimen which can eradicate infection in all the cases has not yet been defined. this study was designed to evaluate the efficacy of triple levofloxacin-based versus clarithromycin-based therapy. methods: in this open-label randomized clinical trial study 120 patients who...
Abstract Introduction: Obesity and upper gastrointestinal disorders are the public health problems in the world and Iran. The role of routine preoperative upper gastrointestinal endoscopy of the morbid obese patients undergoing bariatric surgery is a subject of discussion. The aim of this study was to determine the relationship between gastric pathological findings in morbid obese patients w...
Background & Aims: Given that H. pylori infection increases the inflammation of the stomach and duodenum, stomach and duodenal ulcer and gastric adenocarcinoma risk in children, the main purpose in this study was to compare the accuracy of serology and rapid urease test in diagnostic of H. Pylori in children. Materials & Methods: This cross-sectional study was a diagnostic test evaluation th...
BACKGROUND Despite many changes, no large studies comparing the different diagnostic tests for Helicobacter pylori have been performed in the past 10 years. In this time, monoclonal stool antigen immunoassays and in-office 13C-urea breath tests (UBTs) have appeared. The aim of this study was to evaluate the accuracy of invasive and noninvasive tests in a large series of dyspeptic patients. ME...
