Gastric Ulcer and Perforation due to Mucormycosis in an Immunocompetent Patient.

Mucormycosis is a rare and life-threatening fungal infection that is associated with high mortality in immunocompromised individuals. Although it most commonly affects lungs and paranasal sinuses, cases of invasive mucormycosis of the gastrointestinal tract have also been reported. Gastrointestinal mucormycosis (GIM) is most commonly found in the stomach, colon, and ileum.

Imaging-Negative Hepatocellular Carcinoma Presents as an Intrabiliary Mass.

Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related death and one of the most prevalent cancers worldwide. HCC prognosis remains poor with an average survival rate between 6 and 12 months. Obstructive jaundice, as a main clinical feature, is uncommon in HCC.

The effect of wheat bran fiber and calcium supplementation on rectal mucosal proliferation rates in patients with resected adenomatous colorectal polyps.

Colorectal cancers continue as the second most common cause of death from cancer in the United States. Only a few prospective, randomized clinical trials have been performed to evaluate the potential preventive effects of dietary fiber or calcium in patients with an increased risk for the development or recurrence of colorectal cancer. We designed and conducted a double-blinded, placebo-controlled randomized trial involving supplementation of fiber and calcium intake and measurements of [3H]thymidine labeling index (LI) percentages in rectal mucosal biopsies obtained from patients with resected colorectal adenomas to examine the potential mechanisms by which dietary interventions might reduce colorectal cancer risk.

Randomized, double-blinded, placebo-controlled study of effect of wheat bran fiber and calcium on fecal bile acids in patients with resected adenomatous colon polyps.

Background: Ongoing epidemiologic and nutritional studies suggest that colorectal carcinogenesis is consistent with complex interactions between genetic susceptibility and environmental and dietary factors. Among the dietary components found to reduce colon cancer risk are high intakes of dietary fiber and calcium.

Purpose: We designed and conducted a randomized, double-blinded, placebo-controlled trial involving supplementation of the customary dietary intake with fiber and calcium and measurements of fecal bile acids to examine the potential mechanisms by which added dietary interventions might reduce colorectal cancer risk.

A prospective comparison of anoscopy and fiberendoscopy in detecting anal lesions.

With the increase in rectal and perianal disease, thorough examination of this area is necessary in every patient with colorectal complaints. We compared the current fibersigmoidoscope and colonoscope with routine anoscopy in the detection rate of perianal pathology in 115 consecutive patients. Straight withdrawal and retroflexion in the rectum of the fiberoptic instruments led to lesion detection rates of 78% and 54%, respectively.
