Vitamin B12 or cobalamin deficiency occurs frequently (> 20%) among elderly people, but it is often unrecognized because the clinical manifestations are subtle; they are also potentially serious, particularly from a neuropsychiatric and hematological perspective. Causes of the deficiency include, most frequently, food-cobalamin malabsorption syndrome (> 60% of all cases), pernicious anemia (15%...

The pathology of the parathyroid glands in two cases in which hyperparathyroidism was associated with chronic renal disease and 10 in which the association was with the malabsorption syndrome is described. It is concluded that whereas in chronic renal disease the development of an autonomous adenoma may be preceded by anatomical secondary diffuse hyperplasia such a stage is not proven when the ...

Cases of sprue-like enteropathy associated with olmesartan have sporadically been encountered since it was first reported in 2012, and their most characteristic manifestation is severe diarrhea. We herein report the first case of sprue-like enteropathy manifesting as Wernicke-Korsakoff syndrome due to vitamin B1 malabsorption with only minimally increased bowel movements. When patients are rece...

BACKGROUND Lactase is an enzyme involved in the hydrolysis of lactose. Deficiency of the enzyme (hypolactasia) may be determined genetically or arise secondarily to disease of small intestine. Under this condition, lactose enters the colon where it is fermented by intestinal microflora and turns to gases and short-chain fatty acids, causing gastrointestinal symptoms known as lactose intolerance...

AIM Tropical sprue was considered to be the most important cause of malabsorption in adults in India. However, several reports indicate that celiac disease is now recognized more frequently. METHODS We analyzed the clinical presentation, endoscopic and histological features of 94 consecutive patients (age >12 years) with chronic diarrhea and malabsorption syndrome. The spectrum of disease in ...

The major purpose of this research was to gain insight into the effect of carbohydrate malabsorption on fecal water output. To do this we measured daily fecal output of total carbohydrate, reducing sugars, and organic acids (a product of bacterial fermentation). Normal subjects were studied in their native state and when diarrhea was induced by mechanisms that did and did not involve carbohydra...

Nutritional management of patients with intestinal failure often includes the use oligomeric formulas. Implementing formulas in surgical maldigestion or malabsorption could be a nutritional strategy to included clinical protocols. We aim generate knowledge from survey focused on effectiveness therapy Delphi methodology. Each statement that reached an agreement consensus among participants was d...
