Peritoneal dialysis (PD) peritonitis is usually caused by infection and less commonly by a sterile inflammatory reaction. ⋯ This is the first reported case of noninfectious PD peritonitis caused by pancreaticoduodenocystotomy leak in a patient with a functional pancreas transplant.

Potassium-rich cardioplegia has advantages over other cardioplegic solutions in preserving the myocardium during cardiopulmonary bypass, but it is avoided in patients with renal failure because of hyperkalemia. ⋯ IHD effectively and safely removes potassium administered during potassium-rich cardioplegia during cardiopulmonary bypass in patients with renal failure and prevents postoperative hyperkalemia in the majority of patients. Overall mortality in patients with acute and chronic renal failure undergoing cardiac surgery is high irrespective of control of potassium balance in these patients.

Infection of a renal or hepatic cyst is a serious complication of autosomal dominant polycystic kidney disease (ADPKD). Although crucial for successful management, early diagnosis is difficult, largely because of nonspecific symptoms and limitations of conventional imaging techniques. Because of an increased metabolic rate, inflammatory cells take up large amounts of glucose. 18-F-fluorodeoxyglucose (FDG), therefore, represents a promising agent for detection of cyst infections using positron emission tomography (PET). ⋯ In these patients, FDG PET proved very helpful in diagnosing and in excluding renal and hepatic cyst infections. It is concluded that FDG PET is a promising new imaging technique enabling early identification of renal and hepatic cyst infections in ADPKD patients.

There is growing use of continuous renal replacement therapy (CRRT) for pediatric patients, but no large studies reporting CRRT use and outcome in young children. We describe a cohort of patients weighing 10 kg or less who underwent CRRT at five US children's hospitals between 1993 and 2001. ⋯ CRRT is feasible and useful in children weighing 10 kg or less. Hemodynamic instability requiring pressor support neither precludes successful CRRT nor adversely affects survival. After CRRT, the survival rate in children who weigh 3 to 10 kg is similar to that in older children and adolescents.
