Abstract

Sixteen children with refractory diarrhea and three malnourished children who had frequent episodes of acute gastroenteritis but little diarrhea at the time of hospital admission, were studied by peroral upper small intestinal biopsy. Six children were adequately nourished; five children weighed 62 to 79% of expected weight and eight weighed less than 60% of expected weight. Two of the malnourished children had giardiasis. Pathogenic bacteria were found in only one case. Varying degrees of mucosal atrophy with reduction of mean villous height were seen in 18 cases. The concentration of mononuclear inflammatory cells and plasma cells was about half that seen in well-nourished children with severe nongastrointestinal infections. The concentration of mononuclear cells in the lamina propria was about twice that seen in normal adults. The proportions of IgA-producing cells and cells that stained for secretory component were significantly reduced, as compared with normal adult control values. This reduction was most striking in children with malnutrition complicated by giardiasis. Enzyme histochemical studies were performed for leucine aminopeptidase, alkaline phosphatase and acid phosphatase. There was a tendency for considerably re...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.
