Randomized Controlled Trial Clinical Trial
Failure of continuous venovenous hemofiltration to prevent death in paraquat poisoning.
Paraquat poisoning is characterized by multiorgan failure and pulmonary fibrosis with respiratory failure. Multiorgan failure with circulatory collapse is a major cause of early death within 3 days of paraquat ingestion. Recent studies suggested that continuous venovenous hemofiltration (CVVH) had a role in the treatment of multiorgan failure by promoting hemodynamic stability. ⋯ In the HP group, early circulatory collapse was a major cause of death compared with the HP-CVVH group, in which late respiratory failure was a major cause of death. In conclusion, prophylactic CVVH after HP prevented early death caused by circulatory collapse and prolonged survival time. However, it could not prevent late death caused by respiratory failure and did not provide a survival benefit in acute paraquat poisoning.

Dialysis facilities face important trade-offs between cost and quality under constrained capitated reimbursement. How management at dialysis facilities makes decisions affecting cost and quality of care and views opportunities and threats is unknown. We conducted a national survey of dialysis facility administrators. ⋯ We conclude that increases in facility reimbursement generally would be used by dialysis facility administrators for the benefit of patients, whereas decreases (or inflation erosion) in payment rates might compromise staffing. US dialysis administrators support sharing treatment options and outcomes information with patients, but appear to be ambivalent with regard to linking reimbursement to adequacy of dialysis or patient outcomes. These results have important implications regarding proposed changes in the US capitated dialysis payment rate and current efforts to empower consumers of dialysis care.

A 61-year-old Caucasian man presented with acute renal failure after multiple wasp stings. The patient required dialysis support temporarily. ⋯ Acute renal failure after wasp stings is typically caused by acute tubular necrosis in the setting of hemolysis or rhabdomyolysis. Compared with previously reported cases of acute renal failure associated with bee stings, our patient is unique in that his renal failure was caused by a hypersensitivity reaction apparently to the wasp venom.

Case Reports
Combined medical surgical therapy for pulmonary mucormycosis in a diabetic renal allograft recipient.
Mucormycosis is a rare opportunistic infection that complicates chronic debilitating diseases and immunosuppressed solid-organ transplant recipients. We present a case of life-threatening pulmonary mucormycosis in a diabetic renal allograft recipient who survived with reasonable renal function. ⋯ Antifungal therapy combined with early surgical excision of infected, necrotic tissue appears to be the preferred course of action. Judicious withholding of immunosuppressants until fungemia cleared did not jeopardize allograft function.

Urinary infection is a common complication after kidney transplantation. In some instances, especially with Escherichia coli infections, there is formation and collection of gas in the parenchyma and collecting system of the kidney, giving rise to the condition of emphysematous pyelonephritis. ⋯ This process has not been described so far. In this report, we describe the first case of an infected urinoma with an interesting radiologic finding, a so-called emphysematous urinoma.
