Celiac crisis with hypokalemic paralysis in a young lady.

Celiac crisis presents as severe acute diarrhea with life-threatening metabolic derangement in a patient with celiac disease. We report a 30-year-old lady who was admitted with one-month history of worsening small bowel-type diarrhea. She developed acute quadriparesis due to refractory hypokalemia. Celiac disease was diagnosed on the basis of positive serology and histological features. She improved with aggressive correction of hypokalemia and gluten-free diet. Celiac crisis is a rare presentation of this heterogeneous disease in adulthood.

Cytomegalovirus involving gastric antrum in immunocompromised hosts: a report of 5 cases.

Cytomegalovirus infection, which is common in immunosuppressed patients, only rarely affects the stomach, especially the gastric antrum. We report five patients with cytomegalovirus infection of the stomach with antral involvement. Of these, four had undergone renal transplant and one had HIV infection. All patients presented with upper gastrointestinal symptoms that did not respond to proton pump inhibitors and prokinetic drugs. In addition, all had systemic symptoms. Diagnosis was made at upper GI endoscopy and biopsy, and ganciclovir treatment led to improvement.
