background: this study investigated the interaction between heterotrophic bacteria and coliform, fecal coliforms, fecal streptococci bacteria in water supply networks. methods: this study was conducted during 2013 on water supply distribution network in aq qala city, golestan province, northern iran and standard methods were applied for microbiological analysis. the surface method was applied t...
Prior to implementation of volatile organic compound (VOC) analysis in clinical practice, substantial challenges, including methodological, biological and analytical difficulties are faced. The aim of this study was to evaluate the influence of several sampling conditions and environmental factors on fecal VOC profiles, analyzed by an electronic nose (eNose). Effects of fecal sample mass, water...
Clostridium difficile toxin was checked in fecal extract of 62 ulcerative colitis patients and 62 normal controls, by Elisa and cell culture methods. Clostridium difficile toxin was found in 48.71 percent of ulcerative colitis patients in their acute exacerbations, and in 26.08 percent of cases in their remissions. This toxin was found in the fecal extract of only 3 percent of normal controls. ...
fecal incontinence is a challenging condition in that it exerts various psychosocial impacts on daily life. different treatment modalities have been suggested for fecal incontinence. the present study aimed to evaluate the efficacy of biofeedback therapy in combination with surgery in the management of fecal incontinence. the present randomized controlled trial was performed on 27 women with a ...
Background: Fecal incontinence is one of the secondary and serious complications following anorectoplasty operation in the children with Imperforated Anus. Complete rectal dislocation and local spinal defect of the sphincter muscle are the main causes of fecal incontinence in people undergoing surgery for Imperforated Anus. Methods: This retrospective descriptive Case-Series study was performe...
Background Some controversy exists about the role of cecostomy in the management of fecal disorders. The present meta-analysis aims provide a comprehensive evaluation on the role of cecostomy on management of fecal incontinence and constipation in children. Materials and Methods An extensive search was performed on the Medline, Embase, Scopus, and Web of Science until July 2017. Two ind...
Bile acid excretion was studied in 9 human subjects simultaneously by the Lindstedt (Lindstedt, S. 1957. Acta Physiol. Scand. 40:1-9) isotopic turnovermethod and by fecal chemical analysis during a balance study. The identities of the fecal bile acids were confirmed by combined gas-liquid chromatography/mass spectrometry. Under the steady state conditions of the patient studies, bile acid excre...
Background and Aim: The human bowel contains a large and dynamic bacterial population (more than 500 species of bacteria). Some intestinal bacteria such as Streptococcus bovis , Enterococcus and Bacteroides fragilis have previously been suggested to be implicated in the promotion of colon carcinogenesis probably through the conversion of mutagen metabolites. Materials and Methods: Thirty patie...
Background & Aims: Probiotic bacteria have beneficial effects on host's health. However, one of the most important reasons which affect the probiotic activity of a microorganism is its survival during the gut transit. Microencapsulation techniques could be applied to bacteria to improve this parameter. Methods: In this study, feces of 60 healthy volunteers were analyzed during 28-day test perio...
