We report on a boy with Henoch-Schönlein purpura in whom flank pain and gross hematuria developed during the early phase of the disease. Urologic investigations revealed hydronephrosis and ureteral stenosis. Pyeloplasty was done to relieve ureteropelvic junction obstruction. Severe hemorrhagic ureteritis and vasculitis were noted on the ureteral biopsy.(More)
Sarcoidosis is a multi-system disorder characterized by non-caseating epithelioid granulomas in multiple organs. The disease usually presents in young adults and is uncommon in children. Renal involvement can usually occur due to granulomatous interstitial nephritis, but renal failure is uncommon. Corticosteroids are the mainstay of therapy. We present the(More)
We describe the clinical and pathological findings of the hemolytic uremic syndrome (HUS) in two children with human immunodeficiency virus (HIV) infection. Both patients presented with microangiopathic hemolytic anemia, thrombocytopenia, and subsequently developed renal failure. The diagnosis of HUS was confirmed by renal histopathology in both patients.(More)
Using video recordings we have completed the first kinetic analysis of mushroom stem gravitropism. The stem became gravireceptive after completion of meiosis, beginning to bend within 30 minutes of being placed horizontal. Stem bending first occurred in the apical 15% of its length, then the position of the bend moved rapidly towards the base, traversing(More)
At birth, GFR and tubular function of neonates is compromised as compared to older children and adults. These functions are even less developed in premature infants. These facts have a direct bearing on drug dosing, fluid and electrolyte administration, and maintenance of acid-base balance in neonates. Although many detailed methods of assessing renal(More)

The clinical course and follow-up of a child who presented with rapidly progressive renal failure due to dense deposit disease is described. The patient showed a dramatic response to immunosuppressive and anticoagulent therapy. Two and a half years later, a follow-up renal biopsy showed regression of the intramembranous dense deposits on electron(More)
OBJECTIVE Nutrition and growth are important outcome indicators in pediatric (Ped) hemodialysis (HD) patients. We hypothesized that there is a discrepancy among traditional measures of nutrition, and that adequate nutrition may not reliably predict growth. METHODS We assessed longitudinal nutrition and growth parameters in 14 Ped HD patients over 1 year.(More)
