INTRODUCTION The role of infiltrating cells (I.C.), commonly observed in the adenoma interstitial tissue, is unknown. We tested the hypothesis that I.C. are related with BPH progression by: phenotypically characterising these cells; quantifying the expression of lymphokines and growth factors; investigating the response to Permixon (P) in a clinical study.(More)
Cutaneous infections by nontuberculous mycobacteria (NTM) are not usual but their relative importance has changed during the last few years and still further changes are expected. This study comprised 13 patients from whom NTM were recovered from skin biopsy specimens, sinus exudates or cutaneous abscesses. All samples were processed according to standard(More)
Recurrent acute postinfectious glomerulonephritis is infrequent in childhood and exceptional in adults. The factors that determine recurrence are poorly understood. Selective IgA deficiency is characterized by an increased incidence of gastrointestinal and respiratory infections. The case of a 33-year-old man with a history of repetitive sinopulmonary(More)
Cidofovir is an antiviral drug with activity against a wide array of DNA viruses including poxvirus. The therapeutic use of cidofovir is marred by a dose-limiting side effect, nephrotoxicity, leading to proximal tubular cell injury and acute renal failure. Treatment with cidofovir requires the routine use of prophylactic measures. A correct knowledge of the(More)
The final report of a long-term nonrandomized controlled trial of phenytoin therapy in patients with IgA nephropathy is presented. The mean time period of follow-up was 17 months (range 6-48) in the treated group (41 patients) and 14 months (range 6-36) in the nontreated group (32 patients). Both groups were comparable in age, sex, onset of the nephropathy,(More)
Macroscopic haematuria of glomerular origin has been associated with acute kidney injury. We report a patient with IgA nephropathy, macroscopic haematuria and acute kidney injury. Systemic anticoagulation may have aggravated haematuria. There was extensive interstitial and intratubular red blood cell extravasation, and interstitial haemosiderin deposits.(More)
This study was undertaken to examine the effect of the major immunosuppressive drug, cyclosporin A (CyA), on endothelial function. Conscious Wistar rats, treated with CyA (25 mg.kg-1 x day-1 im for 15 days), developed an inhibition of the endothelium-dependent acetylcholine (ACh)-mediated vasodilation, diuresis, natriuresis, and guanosine 3',5'-cyclic(More)
This paper present the case of a man 72 year old with secondary penis cancer, as a late manifestation of a earlier well differentiated prostate focus, identified by P.A.A.F., which determined the rarity of the presentation and the choice of diagnostic method by puncture-aspiration with a thin needle. Treatment is very complex and neither radiotherapy nor(More)
The different models of experimental IgA nephropathy described so far have provided insight into pathogenesis; however, the evidence for a role of IgA immune complexes (IC) has only been gained in passive systems. In an active model of IgA nephropathy, induced in mice by repeated injections of dextran, some of the mechanisms that could explain the formation(More)
