increasing dysuria and discomfort and was passing debris. Various organisms including Proteus mirabilis, Candida albicans, Escherichia coli, and Pseudomonas aeruginosa were isolated on different occasions and he received a variety of antibiotics including augmentin, nalidixic acid, and gentamicin. He was finally admitted in November 1985 as an emergency with severe pain. Cystotomy was undertake...

background: helicobacter pylori infection is the most common gastrointestinal bacterial disease worldwide. although using culture is considered as the golden standard method for diagnosis of h. pylori infection, urea breath test is a notable alternative method because it is an easy, quick, and non-invasive approach. the aim of this study was to estimate the prevalence of h. pylori infection in ...

objective: childhood infectious diseases are one of the most known environmental pathogenic causes of childhood asthma. the high prevalence of both helicobacter pylori infection and asthma in our country prompted us to assess anyprobable as- sociation between them in childhood. methods: this cross-sectional study recruited 196 children aged 6 to 12 years old comprising 98 asthmatic (case group)...

Background: Recent studies support that intestinal microbes contribute to human disease, and enteric methanogens have been specifically linked to altered gut metabolism and weight gain. In this study, we tested whether methane on breath test (as a surrogate for colonization with the predominant methanogen Methanobrevibacter smithii) is associated with altered glucose tolerance in humans. Method...

BACKGROUND Acetic and propionic acids are produced by colonic bacterial fermentation of unabsorbed carbohydrates and are absorbed into the portal circulation. From there, they travel to the liver, where acetate is a lipogenic substrate and propionate can inhibit lipogenesis. The extent to which peripheral blood short-chain fatty acid concentrations reflect differences in colonic fermentation is...

BACKGROUND AND AIMS Breath hydrogen testing after lactulose administration may yield findings of clinical value, but whether it should be a routine part of breath testing has not been evaluated. We examined the contribution of breath testing after lactulose administration to the conduct and interpretation of breath hydrogen responses after fructose and lactose administration. METHODS Two hund...

background: gestational diabetes mellitus (gdm) is the most common metabolic complications of pregnancy and causes fetal mortality and morbidity. therefore early diagnosis of gdm is necessary to reduce maternal and fetal morbidity and to help prevent or delay the onset of type 2 diabetes objective: this prospective study was carried out to determine the incidence of gdm in yazd and to assess th...

Evidence is increasing that defective metabolism of postprandial remnants of triglyceride-rich lipoproteins contributes to atherogenesis. In obesity, postprandial lipemia is increased by mechanisms that are not currently established. In the present study, a recently developed (13)CO(2) breath test was used to assess the metabolism of chylomicron remnants (CR) in obese mice. Six murine obese mod...

This study aimed to evaluate changes in glucose metabolism at the early stage and onset of diabetes in Otsuka Long-Evans Tokushima Fatty (OLETF) rats. Specifically, after the oral administration of [1, 2, 3-13C]glucose, the levels of exhaled 13CO2, which most likely originated from pyruvate decarboxylation and tricarboxylic acid, were measured. Eight OLETF rats and eight control rats (Long-Evan...

BACKGROUND & AIMS To date, no studies concerning the presence of small intestinal bacterial overgrowth in patients with progressive familial intrahepatic cholestasis were published. Based upon characteristic of progressive familial intrahepatic cholestasis one can expect the coexistence of small intestinal bacterial overgrowth. The aim of the study was to assess the incidence of small intestina...
