BACKGROUND Villous adenoma arising in the urinary tract is rare tumor. Most cases have been identified as benign neoplasm in the colon. Villous adenoma of the gastrointestinal tract is thought arise from premalignant polyps. Here, we report a case of concurrence of villous adenoma and non-muscle invasive bladder cancer. CASE PRESENTATION An 85-year-old woman presented at our office because of...

Two trials involving a total of 56 pigs were conducted to examine the effects of weaning at 7 d of age (trial 1) and of energy intake level and length of post-weaning underfeeding period (trial 2) on small intestinal (SI) development and morphometry. At 3 d after weaning, weight of the SI and mucosa (g/kg body weight) and villous height along SI were reduced by 20, 36 and 41%, respectively, com...

BACKGROUND Endoscopy and biopsy are used to diagnose coeliac disease. There are, however, observer-dependent interpretations of the degree of villous atrophy in biopsies. A pilot study using quantitative image-processing procedures was performed to quantify the degree of villous atrophy in patients with coeliac disease. METHOD The degree of villous atrophy in duodenal biopsy images was quanti...

The villous tree of the human placenta is a complex three-dimensional (3D) structure with branches and nodes at the feto-maternal border in the key area of gas and nutrient exchange. Recently we introduced a novel, computer-assisted 3D light microscopic method that enables 3D topological analysis of branching patterns of the human placental villous tree. In the present study we applied this nov...

BACKGROUND Magnification endoscopy (ME), with 115-fold magnification, allows visualization of duodenal villi. We assessed the efficacy of ME for evaluation of villous atrophy. METHODS ME and duodenal biopsy were done in 16 patients with suspected celiac disease and 16 control subjects undergoing endoscopy for reflux symptoms. The pathologist was unaware of the ME findings. RESULTS Sensitivi...

Celiac disease is the most important cause of intestinal villous atrophy. Seronegative intestinal villous atrophy, including those that are nonresponsive to a gluten-free diet, is a diagnostic challenge. In these cases, before establishing the diagnosis of seronegative celiac disease, alternative etiologies of atrophic enteropathy should be considered. Recently, a new clinical entity responsibl...

BACKGROUND Environmental enteropathy (EE) is an asymptomatic abnormality of small bowel structure and function, which may underlie vaccine inefficacy in the developing world. HIV infection co-exists in many of these populations. There is currently no effective treatment. We conducted a secondary analysis of a randomised controlled trial of high dose multiple micronutrient (MM) supplementation o...

Historically it has been shown repeatedly that single high doses of radiation do not allow a therapeutic differential between tumor and critical normal tissues but dose fractionation does. The purpose of conventional dose fractionation is to increase dose to the tumor while preserving normal tissue function. Tumors are generally irradiated with 2Gy dose per fraction delivered daily to a more or...
