Background: This study was to determine the sensitivity, specificity, positive predictive value (PPV), negative predictive values (NPV) and agreement between two methods of the stained gastric imprint cytology smears and stained gastric specimen biopsy mucosal methods for detection of H. pylori. Methods: Air-dried imprint smears of gastric biopsies from 330 patients were stained by the Grunwal...

Applications Of The Immune-Histochemical Technique For Diagnosis Helicobacter Pylori From Gastric Biopsy Samples

abstract       background and objective: baba2 and hpa genes are involved in adherence of helicobacter pylori (h.pylori) to gastric mucosal tissue. this study aimed to investigate the frequency of these genes in isolates of h. pylori from gastric biopsies and their relationship with gastritis, peptic ulcer and gastric cancer.       methods: gastric biopsy samples were obtained from patients wit...

background: blood group antigen binding adhesin ( baba2 ) , is essential for attachment of helicobacter pylori (h. pylori) to the epithelial cell layer and is the most important adhesin of h. pylori . the prevalence rate of the baba2 gene varies in different geographic areas. the aim of this study is to determine the frequency of the baba2 gene in patients with different clinical outcomes. mate...

Endoscopic gastric biopsy specimens taken in 1976 from 174 patients were reviewed. Biopsy specimens from 44 patients showed intestinal metaplasia, and subtyping by mucin histochemistry showed that 16 were of type I, 14 of type II, and 14 of type III. Only two of these 174 patients developed gastric adenocarcinoma over the next 10 to 11 years: one with type II and one with type III intestinal me...

objective: current of antibiotic treatment for h.pylori infection is often associated with frequent adverse effect and resistant to antibiotic. alternative treatment method to control h.pylori infection is needed. the aim of this study was to test in vitro anti helicobacter activity of lactobacilli acidophilus isolated from yogurt. material and methods: forty h.pylori strains isolated from 145...

RATIONALE There is currently no consensus on the ideal method for obtaining deep tissue biopsy material of advanced gastric LP. EUS-FNA has potential as a useful diagnostic method. Thus, we report the case of a 46-year-old male with advanced gastric linitis plastica (LP) who was diagnosed using endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). PATIENT CONCERNS The patient underwe...
