Small intestinal bacterial overgrowth is common after gastrectomy but with little impact on nutritional status.

Background: Available evidence assessing the impact of small intestinal bacterial overgrowth (SIBO) following gastrectomy is limited.

Objectives: To evaluate the prevalence of SIBO after gastrectomy and its association with malnutrition. To describe the antibiotic treatment required to correct it and if nutritional status improves.

Relevance of GSTM1, GSTT1, and GSTP1 gene polymorphisms to gastric cancer susceptibility and phenotype.

Human glutathione S-transferases (GSTs) are phase II metabolizing enzymes that play a key role in protecting against cancer by detoxifying numerous potentially cytotoxic/genotoxic compounds. The genes encoding the human GST isoenzymes GSTM(mu)1, GSTT(theta)1 and GSTP(pi)1 harbour polymorphisms, which have been considered important modifiers of the individual risk for environmentally induced cancers such as gastric cancer (GC). However, results are inconsistent among studies from different geographic areas and ethnic groups.

[Distinct clinical presentations of a single medical entity: eosinophilic enteritis].

Eosinophilic enteritis is a rare disease characterized by eosinophilic infiltration of different wall layers of the gastrointestinal tract, from the esophagus to the rectum, by eosinophilic cells. The most frequently affected structures are the stomach and small intestine. The pathogenesis of eosinophilic enteritis is not well understood and is often related to a personal or familial history of atopy.
