Enterolithiasis in a Patient With Prior Bowel Resection.

Enterolithiasis is the development of intestinal stones, thought to be related to conditions that predispose to stasis and stricture of the intestines and disruption of chemical factors such as pH. It has been described in the setting of inflammatory bowel disease, intestinal tuberculosis, and prior surgery of the bowel. Our patient was a 68-year-old Caucasian female with prior bowel resection secondary to hernia repair who presented many years later with obstructive symptoms including abdominal pain, nausea and vomiting, and ultimately inability to tolerate oral intake.

Complicated Diverticulitis in a 35-Year-Old Patient With Williams Syndrome: A Case Report.

Williams syndrome is caused by a deletion of the elastin gene on chromosome 7. One of the main roles of this gene is to maintain the strength and elasticity of the intestinal wall, and the absence of the elastin gene may predispose these patients to gastrointestinal pathology such as diverticulitis. Our patient was a 35-year-old Caucasian female with Williams syndrome who presented to the emergency department with diffuse abdominal pain for two days.

Rab11b resides in a vesicular compartment distinct from Rab11a in parietal cells and other epithelial cells.

The Rab11 family of small GTPases is composed of three members, Rab11a, Rab11b, and Rab25. While recent work on Rab11a and Rab25 has yielded some insights into their function, Rab11b has received little attention. Therefore, we sought to examine the distribution of endogenous Rab11b in epithelial cells.
