[Effect of cow's milk elimination from children diet on chronic constipation]

Children constipation is one of the common causes of abdominal pain. Cow's milk in children diet is suggested to be one of the main cause of chronic constipation. This study was performed to determine the effect of cow's milk elimination from children diet with chronic constipation. This quasi-experimental study, was performed on 80 children with chronic constipation. Rome-III criteria were considered for disease diagnosis. Cow's milk was eliminated for three weeks from children's diet and the clinical symptoms in children were surveyed, subsequently. Constipation was cured in 33.8% of children as result of cow's milk free diet. The rate of treatment response in affecting children whom their disease in began under 2 years of age [52.6%] was significantly higher than others [16.6%] [P<0.05]. Children treatment was not significantly related to child's gender and amount of milk consumption. Eliminating of cow's milk from the diet improves the chronic constipation in children

[Colonoscopic and histopathological findings in patients with hematochezia]

Colonoscopy is the best method for management of patients with Hematochezia or lower gastrointestinal bleeding [LGIB]. This study was conducted to assess the endoscopic and histopathologic findings in patients with hematochezia. This descriptive -analytical study was done on 117 [50 males, 67 females] patients whom referred to 5th Azar hospital in Gorgan, northern Iran during 2010. Demographic characteristics, medical history and colonoscopic and histopathologic findings were recorded for each patient. Hemorrhoid was the most common finding in colonoscopic examination. Inflammatory bowel disease [IBD] and cancer were the most common feature in the under and higher than 43 age old patients, respectively [P<0.05]. Ulcerative colitis [22.2%] was the most common finding in histopathological examination. Rectosigmoid was the most common anatomical location of involvement in IBD cases. Cancer and IBD were occurred in the left colon. Flexible sigmoidoscopy can be a selected procedure for evaluation of hematochezia in the <43 age old patients but in >43 age old subjects sigmoidoscopy or colonoscopy should be made based on patients' status

[Tissue trans-glutaminase antibody in inflammatory bowel disease in golestan province, Northern Iran [2005-08]]

Celiac is a hereditary disease presented with chronic inflammation of small intestine. Several studies supposed a relationship between Celiac disease and Inflammatory Bowel Disease [IBD]. Tissue trans-glutaminase antibody is one of the best serological markers in Celiac disease. This study was designed to evaluate the association of Celiac and IBD using tissue trans-glutaminase antibody. In this descriptive study 127 confirmed IBD patients who were referred by gastroentrologists 2005-08 enrolled into the study. A questionnaire was completed and tissue trans-glutaminase antibody was evaluated with ELISA method with a Cut-off=12 U/ml. Among 127 referred patients, serum samples of 102 patients were collected. Mean +/- SD of age was 36.17 +/- 15.2 years and 48% were males. Ulcerative colitis, Crohn's disease and other colitis were observed in 76 [74.5%], 7 [6.9%] and 19 [18.6%] of patients, respectively. Tissue trans-glutaminase antibody was positive [19.8 U/L] in one 46-years-old male patient with ulcerative colitis. Tissue trans-glutaminase antibody titer was not significantly different between IBD patients and controls, thus it seems not appropriate to suggest as one of the routine tests in IBD patients
