Any intestinal torsion is only possible because the intestine itself is long enough to turn around itself. However, the anatomic fixation of the cecum and intestinal parts in close proximity may particularly predispose it for torsions: patients affected by CV exhibit a common mesentery that is rather long and only…

Infection with the protozoan parasite E histolytica is associated with proteolysis, tissue damage and host-cell apoptosis in humans and presumably nonhuman primates. Ingested E histolytica cysts from contaminated food and water or oral-anal sex undergo excystation in the terminal ileum or colon. Each mature cyst…
