Trichobezoar causing pancreatitis: first reported case of Rapunzel syndrome in a boy in North America.

Trichobezoar is a mass of hair retained in the stomach, usually associated with trichotillomania. Large trichobezoars may extend into the small bowel and cause small bowel obstruction or pancreatic dysfunction, a condition known as Rapunzel syndrome. Here we report the first North American case of Rapunzel syndrome in a male patient.

A murine model of chronic mucosal colonization by Pseudomonas aeruginosa.

Chronic mucosal colonization by Pseudomonas aeruginosa is an integral part of the pathologic process associated with disease due to infection with this organism. We have adapted the streptomycin-treated murine model of chronic mucosal colonization by enteric pathogens to study colonization by P. aeruginosa.
