OBJECTIVES CD40L is a costimulatory molecule and an early activation marker of T-lymphocytes. Based on the hypothesis that activated T-cells may play a role in the pathogenesis of psoriatic arthritis (PsA), we evaluated the level of CD40L expression on T-cells from patients with PsA. METHODS We analysed 12 patients with PsA, six patients with rheumatoid(More)
OBJECTIVES To assess the surgical and long-term results of renal transplantation in 25 patients with bladder dysfunction and augmentation cystoplasty. METHODS We retrospectively reviewed the evolution and surgical outcome of 25 renal transplants in 24 recipients with augmentation cystoplasty. The mean patient age at transplantation was 27.6 years. The(More)
INTRODUCTION Infected incisional hernias are common in kidney transplant patients. Treating them in immunosuppressed patients can take months, increasing costs and implying loss of working productivity. Abdominal wall prostheses have not been used in infected immunosuppressed patients because of poor infection control. We evaluated the outcome of the(More)
OBJECTIVES The present study aimed to evaluate the prevalence and associations of renal dysfunction in patients with rheumatoid arthritis (RA). It specifically addressed the hypotheses that renal dysfunction in these patients may associate with the presence of insulin resistance, dyslipidaemia, uric acid levels and/or current levels of systemic(More)
PURPOSE We evaluate the incidence of incisional hernia after kidney transplantation, predisposing factors and the results of surgical repair with polypropylene mesh. MATERIALS AND METHODS We reviewed the records of 371 consecutive kidney transplants performed between April 1995 and February 2000. Patients with clinical signs of hernia at the transplant(More)
PURPOSE We examined the development of urological abnormalities in a group of pediatric renal transplant recipients. MATERIALS AND METHODS We reviewed 211 patients younger than 19 years who underwent 226 renal transplants. Three groups of patients were studied-136 children with end stage renal disease due to a nonurological cause (group 1), 56 children(More)
PURPOSE Transplant nephrectomy has been considered a hazardous procedure throughout transplantation history. Better surgical techniques and clinical treatment of patients have improved the results of this surgery in the last decades. We report the surgical complications of nephrectomy of early and late failed kidneys performed at a referral center. (More)
OBJECTIVE To investigate the feasibility of radical retropubic prostatectomy (RRP) in renal transplant recipients with clinically localized prostate cancer. METHODS A prospective protocol was established between August 2004 and November 2007. In that period, 8 patients diagnosed with localized prostate cancer were submitted to RRP, and their(More)
To describe a single-center experience with kidney transplantation and then study some donor and recipient features that may impact on graft survival and urological complication rates. We reviewed our database searching for pediatric patients who underwent kidney transplantation from August 1985 through November 2012. Preoperative data and postoperative(More)
