Hyperemesis Gravidarum in Undiagnosed Gitelman's Syndrome.

Introduction. Gitelman's syndrome (GS) is an autosomal recessive inherited defect in the thiazide-sensitive sodium-chloride cotransporter (NCCT) in the renal distal convoluted tubule. Physiologic changes of pregnancy promote renal potassium wasting, but serum potassium levels are kept in the physiologic range by increased levels of progesterone, which resist kaliuresis.

An intra-abdominal abscess or "rind" as a consequence of peritoneal dialysis-associated pseudomonas peritonitis.

Background: Abdominal CT imaging has defined characteristics of two pathological entities specific to peritoneal dialysis patients. Both are associated with serious peritoneal complications. One is comprised of ascites accompanied by septation and loculated fluid pockets as a complication of bacterial peritonitis.

Primary renal zygomycotic infarction mimicking renal neoplasia in an immunocompetent patient.

Isolated renal infections with fungal organisms of the class Zygomycetes are rare, but these infections are most frequently seen in patients who are immunocompromised. We report the case of a 45-year-old African American man who presented with symptoms of right-sided pyelonephritis, including fever, dysuria, and flank pain. The patient's history was significant only for sickle cell trait, and no evidence of immunosuppression was identified.
