Background: Enteric viruses, particularly human rotavirus and norovirus, have been shown to replace bacteria and parasites, as the most common pathogens responsible for acute diarrhea. However, there are still few epidemiological data on the simultaneous occurrence of these viruses in Iran. In this regard, the aim of this study was to assess the useful epidemiological data on the gastroenteriti...

BACKGROUND Many case reports of acute pancreatitis have been reported but, up to now, pancreatic abnormalities during acute gastroenteritis have not been studied prospectively. OBJECTIVES To evaluate the incidence and the clinical significance of hyperamylasemia in 507 consecutive adult patients with acute gastroenteritis. METHODS The clinical significance of hyperamylasemia, related predis...

BACKGROUND There is evidence that endogenous nitrate synthesis is notably increased in patients with infective gastroenteritis. AIMS To determine whether this is due to nitric oxide (NO) production via the L-arginine/NO pathway. METHODS Seven male patients with community acquired bacterial gastroenteritis and 15 healthy male volunteers participated in this study. All patients had stool cult...

A 57-year-old woman was admitted to our hospital because of frequent bloody diarrhea, vomiting, and abdominal cramps. While the patient was diagnosed with norovirus gastroenteritis based on the presence by chance of positive norovirus antigen in the stool samples, endoscopic as well as pathological examinations demonstrated left-sided ischemic colitis. The patient soon recovered solely by suppo...

BACKGROUND While norovirus (NoV) is well known as a leading causal pathogen for acute gastroenteritis in developed countries,structured data on prevalence in developing countries are not available thus far. This review aims to estimate the prevalence of NoV in cases of gastroenteritis in developing countries based on recently published reports. METHODS Relevant studies were identified by sear...

conclusions the results showed that some patients were probably contaminated with nonbacterial and nonparasitic agents. all the parasitic isolates were resistant to most antibiotics. therefore determination of microbial isolates and antibiotic susceptibility is necessary before treatment procedures. results of 2376 patients, 466 (19.6%) were contaminated with pathogenic bacteria or protozoa.the...

conclusions given the non-specific symptoms of these viruses and the high prevalence of viral diarrhea in our region, more laboratories should be equipped for virus detection and vaccination might be considered as a prevention strategy. results rotavirus was identified in 347 patients out of 827 (42%), adenovirus was detected in 76 (9%) of samples and 34 (4%) of patients had rotavirus-adenoviru...

Benign convulsions associated with gastroenteritis are now recognized as a clinical entity, characterized by an acute cluster of afebrile seizures during an episode of mild diarrhoea with excellent prognosis. We observed 30 children who each experienced at least two seizures associated with mild gastroenteritis. The inclusion criteria were: afebrile seizures during gastroenteritis, dehydration ...

BACKGROUND The aetiology of severe gastroenteritis leading to hospitalisation in adults frequently remains unclear. Our objective was to study the causes and characteristics of community-acquired, acute gastroenteritis in adult hospitalized patients to support the clinical management of these patients. METHODS From August 2005 to August 2007, we conducted a prospective cohort study among pati...

Tropheryma whipplei, which causes Whipple disease, is found in human feces and may cause gastroenteritis. To show that T. whipplei causes gastroenteritis, PCRs for T. whipplei were conducted with feces from children 2-4 years of age. Western blotting was performed for samples from children with diarrhea who had positive or negative results for T. whipplei. T. whipplei was found in samples from ...
