Exploring Vitamin B12 Deficiency in Sleeve Gastrectomy from a Histological Study of a Cadaveric Stomach and Ileum.

Introduction: Vitamin B12 deficiency is more commonly found among patients who have undergone Roux-en-Y gastric bypass (RYGB) as compared to those with post-sleeve gastrectomies (SG). The major difference between SG and RYGB is that the latter greatly bypasses the stomach whereas the former simply reduces the gastric volume.

Purpose: The aim of this article was to study the stomach and the distal ileum histologically in a cadaver with SG to explain the higher rate of incidences of vitamin B12 deficiency seen in patients post-RYGB relative to patients post-SG.

Hyperinfective strongyloidiasis in the medical ward: review of 27 cases in 5 years.

Background: Hyperinfective strongyloidiasis is rare, but the mortality rate is very high. It occurs most commonly in immunocompromised patients. We reviewed the clinical presentation and mortality rate of cases managed in our facility.
