To determine the incidence and risk factors for neonatal hypertension we studied the entire population of 3179 infants admitted to our neonatal intensive care unit over a 6-year period. We report a 0.81% (26/3179) incidence of hypertension in this population. In 13 patients (50%) the hypertension was renal in origin. In four patients (15.4%), the etiology(More)
In nine children with the Laurence-Moon-Biedl syndrome a high incidence of nephropathy was documented. Renal involvement was noted in seven patients before or simultaneously with the diagnosis of LMBS. Five have uremia and two have died. All patients had an abnormal urogrum. The spectrum of renal lesions ranged from mesangial tissue proliferation to(More)
With the use of information from a database of pediatric patients with concomitant nuclear GFR and serum creatinine (Cr), estimated GFR equations were derived on the basis of local laboratory methods and population. These formulas then were compared with those recommended by the National Kidney Foundation for estimating GFR in children. For this, their(More)
In this randomized double-blind crossover trial we compared the antiproteinuric effects of enalapril and losartan in six children with proteinuria and underlying renal injury. The primary endpoint was reduction in proteinuria during therapy. The study had two 8-week on-drug arms, with a 4-week washout period between. Baseline proteinuria was similar,(More)
A 39 year old man with 4 of the 5 cardinal features of the Laurence-Moon-Biedl syndrome (LMBS) had proteinuria and moderate renal failure. Excretory urography showed small cysts communicating with the dilated calyceal system. Renal biopsy showed diffuse mesangial sclerosis and cellular proliferation. Excretory urograms in 22 of 24 reported patients(More)
Hyperkalemia has been noted to occur spontaneously in patients with long-standing systemic lupus erythematosus who did not have advanced renal insufficiency. The patients previously described all had relatively normal renin-aldosterone systems, and the hyperkalemia was thus presumed to be secondary to a primary defect in renal tubular potassium secretion.(More)
Four of 10 children with SLE kept under observation over the past nine years have developed avascular necrosis (AN) of the femoral head. The symptoms of AN are insidious and unpredictable and predate the radiologic diagnosis by weeks to months. In a comparison of these children with SLE, with and without AN, with a group of patients with nephrosis treated(More)
Two infants with lethargy, vomiting, convulsions, coma and marked metabolic acidosis were found to have very high concentrations of methylmalonic acid in their serum and urine. In vitro studies of fibroblasts demonstrated that the infants had different variants of methylmalonic acidemia.Vitamin B(12) was given in two different forms at 1 month of age and at(More)
The effects of cytarabine (beta-cytosine arabinoside) on glucose metabolism is not well known. The present study showed that 5 mg/kg of cytarabine decreased plasma glucose level in 10 day old rat 4 hours after ip injection. Hepatic glycogenolysis decreased 4 hours after cytarabine injection. Thus, cytarabine alters newborn glucoregulation.
