Objective(s) Resistance to antimicrobial agents, particularly metronidazole and clarithromycin, is frequently observed in Helicobacter pylori and may be associated with treatment failure. This resistance rate varies according to the population studied. The aim of this study was to assess the pattern of antimicrobial resistance of H. pylori isolates from dyspeptic patients in Isfahan. Material...

A number of seemingly neurotic symptoms, similar to those reported in bismuth intoxication, occurred in a patient taking a proprietary dyspeptic preparation, tri-potassium dicitrate bismuthate (De-Nol), over 2 years. The symptoms remitted over 10-12 months after stopping the drug - a similar period to that described in bismuth intoxication and the patient has remained symptom-free for 7 years. ...

The performance of five immunoassays for detection of immunoglobulin G antibody against Helicobacter pylori in 191 dyspeptic patients was evaluated. The sensitivities, specificities, accuracies, positive predictive values, and negative predictive values ranged from 86.32 to 97.89%, 57.95 to 72.22%, 77.02 to 83.76%, 71.54 to 77.42%, and 83.33 to 96.23%, respectively. The immunoglobulin A test ki...

introduction and aims: do h. pylori isolates from normal and dyspeptic patients have similar genetic profiles? since genotype variation occurs within h. pylori population with high frequency, it is tempting to exploit techniques such as rapd-pcr to examine the possible correlation between specific h. pylori genotypes and different peptic diseases. in this study, h. pylori isolates from differen...

The double pylorus is an uncommon finding and maybe congenital due to gastrointestinal duplication abnormality or more commonly secondary to peptic ulcer disease. The case we present is an elderly patient with mild dyspeptic symptoms who had an upper endoscopy as part of her investigative workup. The congenital double pylorus, being asymptomatic, may often go undetected. It is sometimes found i...
