BACKGROUND/AIMS In the Helicobacter pylori (H. Pylori)-negative normal stomach, collecting venules are visible over all the gastric body as numerous minute points evaluated with standard endoscopy. This finding was termed regular arrangement of collecting venules (RAC), and its absence suggests H. pylori gastritis. The aim of this study was to evaluate the correlation between the RAC and rapid ...

OBJECTIVE To investigate the possible role of Helicobacter pylori as a cause of squamous cell carcinoma of larynx in a case-control study in an otolaryngology ward at an academic university. SUBJECTS AND METHODS A total of 65 patients with laryngeal cancer and 65 matched cancer-free controls underwent esophagogastroduodenoscopy and biopsy of antral and body regions of the stomach for evaluati...

BACKGROUND The role of endoscopic biopsies in the detection of Helicobacter pylori in patients with nonulcer dyspepsia is poorly defined. This study assesses the cost-effectiveness of performing routine biopsies for the detection of H pylori at upper endoscopy in these patients. METHODS Clinical decision-making was modeled based on outcomes data from published articles and expert opinion. The...

The gold standard for the diagnosis of Helicobacter pylori infection requires an endoscopic biopsy of gastric mucosa for histological examination, urease test and culture. Noninvasive serological tests are useful as a screening test for H. pylori infection. The aim of this study was to evaluate the performance of a rapid office-based serologic test, using immunochromatography ICM, and the immun...

background helicobacter pylori infection is a common infection that affects human beings. this infection also affects children. different diagnostic methods such as serology, stool antigen detection, rapid urease test and histology are used to detect this microorganism. objectives the aim of this study was to determine the correlation between serology and histology/rapid urease test. patients a...

Helicobacter pylori infection is usually acquired in early childhood and it can persist throughout life without antibiotic treatment. This study aimed to compare the accuracy of the noninvasive H. pylori Stool Antigen Test-applied on the stool samples with the invasive gold standart Rapid Urease Test-applied on the gastric biopy samples of patients with upper gastrointestinal complaints. After ...

introduction: helicobacter pylori infection is likely acquired was in childhood. helicobacter pylori is recognized as a cause of gastritis and peptic ulcer. our objective to investigate some noninvasive tests, particularly serum h pylori igg, for the diagnosis of h pylori infection in comparison with the gold-standard invasive test, esophagogastroduodenoscopy with biopsy (histology and rapid ur...

A total of 140 mycobacterial isolates from patients treated at Fitzsimons Army Medical Center or the National Jewish Hospital and Research Center and from animal specimens submitted to the National Veterinary Services Laboratory were tested by using a urease procedure modified for use with a BACTEC model 301. Mycobacterial suspensions were prepared by using Middlebrook 7H10 Tween broth. Of the ...
