We report an 8-month-old boy with systemic lupus erythematosus and World Health Organization class IV lupus nephritis who has gone into complete clinical and serological remission with pulse i.v. cyclophosphamide therapy. To our knowledge this is the first case of pulse i.v. cyclophosphamide therapy in infantile systemic lupus erythematosus resulting in long-term remission.

An 8-year-old girl who had undergone chronic hemodialysis for 1 year presented with respiratory distress 24 h after a hemodialysis session. She had a massive pleural effusion of the left chest that was shown to be hemothorax by thoracentesis. After chest tube insertion, drainage was maintained for 2 days. ⋯ The antecubital arteriovenous fistula on the left arm was found to have an excessive flow with a thrill which was felt all over her left shoulder and left hemithorax. The pleural effusion resolved spontaneously a week after ligation of the fistula. Excessive flow in the arteriovenous fistula was thought to be the cause of the hemothorax and should be included in the differential diagnosis of hemothorax in hemodialysis patients.

We report our experience with 11 children treated by continuous veno-venous hemodiafiltration. The median age was 5.0 years (range 3 days to 14 years). Access was via dual-lumen subclavian or femoral vein catheters. ⋯ Urea and creatinine clearances were 15.1 +/- 6.4 ml/kg body weight per min and 16.4 +/- 8.4 ml/kg body weight per min, respectively. Metabolic acidosis was readily controlled in all patients. Of the 11 patients, 7 ultimately recovered normal renal function.

The purpose of this study was to identify hypertension in children and adolescents in an early stage of autosomal dominant polycystic kidney disease (ADPKD) by the application of ambulatory blood pressure monitoring (ABPM) over 24 h; 32 children and adolescents (mean age 12.3 +/- 4.7 years) were examined. The diagnosis was based on family history and ultrasound examination. In 21 children ADPKD was confirmed by molecular genetic analysis. ⋯ The nocturnal dip in blood pressure was reduced in 2 patients. Blood pressure correlated with renal size, but not with GFR, concentrating capacity, proteinuria, and plasma renin activity. The study reveals an early trend for increased blood pressure in children with ADPKD, requiring close supervision.

This report describes a neonate with acute renal failure associated with extensive aortic and bilateral renal artery thrombosis attributed to inadequate breastfeeding and severe dehydration. Dialytic and general supportive care, together with concurrent anticoagulation, and continuous aggressive intrathrombic instillation of urokinase for 5 days resulted in near-complete thrombolysis. ⋯ Despite ischemic atrophy of the left kidney, renal function and blood pressure were normal on follow-up. Thus, in neonates thrombolytic therapy may positively impact survival and recovery of renal function even in the setting of prolonged ischemic renal injury.
