Data for 26 patients with membranoproliferative glomerulonephritis, type I (MPGN I) and 22 with membranoproliferative glomerulonephritis, type III (MPGN III), as distinguished by glomerular ultrastructure, were analyzed to determine differences in presentation, complement perturbation, and glomerular morphology by light microscopy. MPGN III was detected(More)
Tacrolimus-based immunosuppression with steroid withdrawal in pediatric kidney transplantation was pioneered at the University of Pittsburgh but is not broadly practiced at other centers. We present our 4-year experience with a modified Pittsburgh protocol at our own moderate-volume center. Seventeen pediatric kidney transplant recipients were treated with(More)
PURPOSE We examined the effects of communication skills training and the use of memory books by certified nursing assistants (CNAs) on verbal interactions between CNAs (n = 64) and nursing home residents (n = 67) during care routines. DESIGN AND METHODS CNAs were taught to use communication skills and memory books during their interactions with residents(More)
PURPOSE We have previously reported a high rate of urinary metabolic abnormalities in stone forming children compared to normal controls. At our institution a 24-hour urine evaluation is initiated after the first stone episode in children, to measure stone risk indices. The purpose of this study was to determine which children are at the greatest risk for(More)
Long term dialysis in children with multiple handicaps has become easier with the advent of CAPD. In December 1986, an 11 year old with myelomeningocele in end stage renal disease secondary to chronic pyelonephritis required dialysis. Placement of a right ventriculoperitoneal shunt had been done at 4 months of age. Poor family compliance required placement(More)
PURPOSE Obstructive uropathy secondary to posterior urethral valves is an important cause of end stage renal disease in children. Early diagnosis and intervention to decrease bladder pressure and stabilize the upper urinary tract are important to delay or prevent the progression of renal insufficiency. We analyzed the records of patients with posterior(More)
Seventeen patients with Type III membranoproliferative glomerulonephritis (MPGN) have been followed for more than two years; 16 were treated with alternate day prednisone. Clinical deterioration correlated with nephrotic syndrome (NS) at diagnosis: 3 of 7 patients with NS at diagnosis developed end-stage disease. Serial biopsies in the others showed(More)
Renal involvement is common in Henoch-Schoenlein purpura (HSP) and, while ureteral obstruction has been described in patients with the disease, it is rare. We report a female with HSP who developed bilateral ureteral obstruction from peri-ureteral vasculitis and subsequent ureteral ischemia. Hydronephrosis and typical findings on contrast urography(More)
PURPOSE To examine the distribution of arterial hypotension surrounding arteriovenous malformations (AVMs) using a standardized system of vascular zones. METHODS Mean arterial pressures were recorded during superselective cerebral angiography in 96 patients with AVMs (before they underwent liquid polymer embolization) with the use of a system of vascular(More)
Tethered cord syndrome (TCS) is defined by abnormal traction on the spinal cord that confines its movement. Surgical cord release usually stops neurological deterioration; therefore, early and accurate neuroradiological diagnosis is important. Supine MRI is the imaging modality of choice, but prone MRI and cine MRI can demonstrate cord movement. We compared(More)
