PURPOSE We evaluated the indications for and outcome of pre-transplant, concomitant and post-transplant native nephrectomy in patients with end stage polycystic kidney disease (PCKD). MATERIALS AND METHODS The records of 32 patients were retrospectively reviewed using the electronic database at our institution. RESULTS Between January 1992 and December(More)
BACKGROUND At our institution, increased kidney donation from unrelated donors accounts for a steady rise in live donor kidney transplantation rates. We compared outcomes of living related (LRT) versus living unrelated kidney transplants (LURT) and analyzed the effect of early rejection upon graft survival. METHODS A retrospective analysis on 428 adult(More)
We have investigated the spontaneous degradation of aspartate and asparagine residues via succinimide intermediates in model peptides in organic co-solvents. We find that the rate of deamidation at asparagine residues is markedly reduced in solvents of low dielectric strength. Theoretical considerations suggest that this decrease in rate is due to the(More)
The non-enzymatic deamidation at residues Asn-12 and Asn-38 of Escherichia coli phosphocarrier protein, HPr, and the repair of the resulting L-isoaspartyl (or beta-aspartyl) derivatives, HPr-1 and HPr-2, by recombinant human S-adenosylmethionine-dependent L-isoaspartate-(D-aspartate) O-methyltransferase (EC were investigated. HPr is a component of(More)
We describe our technique of microlaparoscopic placement of continuous ambulatory peritoneal dialysis catheters. Visualization is achieved using a 2.7-mm microlaparoscope, and intra-abdominal manipulation, as well as catheter placement using the Seldinger technique, is accomplished through a single 5-mm port. The advantages of this method include accurate(More)
Poor early graft function (EGF) after deceased donor kidney transplantation (DDKT) has been intensely studied. Much less is known about poor EGF after living donor kidney transplantation (LDKT). Data were collected on 469 LDKTs performed between 1/1/97 and 12/31/01 to determine risk factors for and outcomes associated with poor EGF, defined as either(More)
We present a case of pneumatosis intestinalis (PI) of the colon in the setting of inflammatory bowel disease that was treated with medical management rather than emergent surgery. While the reflex response to extraluminal air in the abdomen is abdominal exploration, consideration of the clinical context in which PI is discovered and an understanding of a(More)
BACKGROUND In renal allograft recipients presenting with graft dysfunction, it is critical to determine the patency of the transplant vasculature to guide clinical management. Conventional modalities such as Doppler ultrasound, contrast-enhanced computed tomography, magnetic resonance angiography (MRA), and noncontrast MRA are each of limited use because of(More)
Graft-versus-host disease (GVHD) remains the most common cause of nonrelapse-related morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although T-cell depletion and intensive immunosuppression are effective in the control of GVHD, they are often associated with higher rates of infection and tumor recurrence. In(More)
