Although several invasive and noninvasive tests have been developed for the diagnosis of Helicobacter pylori infection, all of the tests have their limitations. We conducted a study to investigate and compare the suitability of rapid urease test (RUT), serology, histopathology and stool antigen tests with polymerase chain reaction (PCR) for detection of H. pylori, and correlate the diagnostic m...
BACKGROUND A diagnosis of H. pylori infection can be made by invasive or non-invasive methods. Several noninvasive diagnostic tests based on the detection of H. pylori stool antigen (HpSA) have been developed. The Genx H. pylori stool antigen card test is a new rapid, non-invasive test that is based on monoclonal immunochromatographic assay. The aim of this study was to determine its sensitivit...
Background and Objective: Chronic and recurrent abdominal pain affect about 7-20% of children in school age, and it is responsible for 2-4% of children's medical referrals. Helicobacter pylori infection in children can cause gastrointestinal problems in childhood, and the lack of treatment and eradication can lead to serious complications. This study was done to evaluate the prevalence of Helic...
We describe a case of ocular (subconjunctival) cysticercosis in a eighteen years old, vegetarian male, who presented to the ophthalmology OPD with complaints of increasing painless conjunctival swelling of left eye since four months associated with redness, restriction of gaze and diplopia. The patient had a history of similar swelling in tongue three months back, which extruded spontaneously. ...
Recent studies suggest that stool antigen assays are more sensitive and specific than microscopy for the diagnosis of Entamoeba histolytica infection. One hundred twelve patients presenting at 3 centers with symptoms or risk factors of E. histolytica infection were prospectively enrolled in this study to evaluate new diagnostic tests for infections with E. histolytica and Entamoeba dispar. Four...
The diagnosis of amebiasis by microscopic identification of the parasite in stool is insensitive and unable to distinguish the invasive parasite Entamoeba histolytica from the commensal parasite E. dispar. In this study, we have tested a PCR technique for the detection of E. histolytica and compared it with isoenzyme analysis and the TechLab E. histolytica-specific antigen detection test. The n...
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...
OBJECTIVE Highly sensitive guaiac-based faecal occult blood (Hemoccult SENSA) and Helicobacter pylori stool antigen testing might help detect upper gastrointestinal lesions when appended to a colorectal cancer screening programme with faecal immunochemical testing. We evaluated the diagnostic accuracies of two stool tests in detecting upper gastrointestinal lesions. DESIGN Cross-sectional des...
Background Dyspepsia is a common presentation for many patients in gastroenterology clinics. Helicobacter pylori (H. pylori) infection is endemic in many countries around the world and its relation to dyspepsia has long been questioned. This study aimed at comparing demographic, endoscopic and histologic features among dyspeptic patients with and without stool H. pylori antigen positivity. Me...
