OBJECTIVE Primary hyperparathyroidism (HPT) is unusual in children. We reviewed our experience with HPT to better characterize these children. METHODS The retrospective review of patients <19 years old who underwent parathyroid resection for primary HPT from 1970 to 2000 was performed at a single institution.. RESULTS Fifty-two patients were identified.(More)
BACKGROUND For a subset of adults and children with primary focal segmental glomerulosclerosis (FSGS), proteinuria and renal dysfunction recur after kidney transplantation (KTx). Predicting recurrence and response to plasmapheresis (PP) or other interventions remains problematic. METHODS The prevalence, recurrence rate, outcomes, and treatment responses(More)
We previously proposed a quantitative approach to assess donor organs for cadaver renal transplantation. To improve on our original scoring system, we studied 34 324 patients who received cadaver renal transplants from adult donors between 1994 and 1999 and were reported to the UNOS Scientific Renal Transplant Registry. A scoring system was developed from(More)
Passive immunization with hepatitis B surface antibody (anti-HBs) is important to prevent hepatitis B virus (HBV) recurrence after orthotopic liver transplantation for chronic HBV cirrhosis. Hepatitis B immune globulin (HBIG) dosing regimens have been poorly defined, utilize numerous routes of administration, and result in a high rate of HBV relapse and(More)
Calcineurin inhibitors have decreased acute rejection and improved early renal allograft survival, but their use has been implicated in the development of chronic nephrotoxicity. We performed a prospective, randomized trial in kidney transplantation comparing sirolimus-MMF-prednisone to tacrolimus-MMF-prednisone. Eighty-one patients in the sirolimus group(More)
BACKGROUND Rising numbers of patients reaching end-stage kidney disease intensify the demand for expansion of the living-kidney-donor pool. On the basis of low risk in white donors with essential hypertension, our transplant center undertook a structured program of accepting hypertensive donors if kidney function and urine protein were normal. This study(More)
BACKGROUND & AIMS Organ donors are a potential source of transmissible disease after transplantation. The aim of this study was to evaluate the risk of acquiring hepatitis B among transplantation recipients of livers from donors without serum hepatitis B surface antigen (HBsAg) but with antibody to hepatitis B core antigen (anti-HBc). METHODS The(More)
The purpose of this study was to characterize the histology of antibody-mediated rejection (AMR) in ABO blood-group-incompatible (ABOI) kidney transplants as well as on protocol biopsies performed at the time of stable allograft function. Between 5/99 and 1/02, we performed 32 ABOI kidney transplants (13 A2, 19 non-A2 blood-group living donors). Nineteen(More)
Acceptance of obese individuals as living kidney donors is controversial related to possible increased risk for surgical complications and concern that obesity may contribute to long-term renal disease. We retrospectively examined 553 consecutive hand-assisted laparoscopic living kidney donations between October 1, 1999 and April 1, 2003. We stratified(More)
BACKGROUND The criteria for living kidney donation are changing, resulting in increased numbers of individuals with risk factors being accepted as donors. The long-term function and volume changes in the remaining kidney of these medically complex donors remain largely unknown. METHODS Living kidney donors with three separate risk factors (older age,(More)
