Mutations of the p53 tumor suppressor gene are the single most common genetic alterations in human cancers. Recently, a distinct nucleotide substitution was identified in exon 10 of the p53 gene, leading to an Arg337His mutation in 97% of children with adrenocortical tumors from Southern Brazil. In the present study, we investigated the presence of this(More)
OBJECTIVE To assess semen analysis, testicular volume, and hormone levels in fertile and infertile patients with varicoceles and fertile men without varicoceles. DESIGN Retrospective study. SETTING Academic medical center. PATIENT(S) Patients were divided into three groups: fertile men with varicoceles (n = 79), infertile men with varicoceles (n =(More)
The objective was to describe the last 10 years’ experience of the diagnosis and treatment of renal, perinephric, and mixed abscesses in an academic reference center. The medical records of 65 patients with renal, perinephric, and mixed abscesses treated at our hospital from January 1992 to December 2002 were reviewed. The data collected included(More)
The AIDS epidemic caused unexpected worldwide levels of tuberculosis, even in developed countries where the incidence used to be low. Patients with urogenital tuberculosis in developed countries have fewer specific symptoms and lower rates of delayed diagnoses compared with patients from other countries. As a result, the disease tends to be less serious,(More)
OBJECTIVES To study the surgical treatment of Peyronie's disease using a single incision in the tunica albuginea and fibrotic plaque and repair of the defect by bovine pericardium graft. METHODS Between April 1999 and May 2001, 33 patients who had had symptoms of Peyronie's disease for more than 12 months and whose disease had been stable for more than 6(More)
ACTH-independent macronodular adrenal hyperplasia (AIMAH) is an uncommon cause of Cushing's syndrome characterized by bilateral nodular adrenocortical hyperfunction in the presence of suppressed ACTH levels. We investigated whether activating mutations in the ACTH receptor (MC2-R) or G(s alpha) (GNAS1) genes might be involved in AIMAH genesis. Five women(More)
BACKGROUND The purpose of this study was to assess the treatment outcome after varicocele repair in azoospermic men and to correlate this outcome with the testicular histology patterns. METHODS Medical records of 15 azoospermic men who underwent testis biopsy and microsurgical repair of clinical varicocele between July 1999 and November 2000 were(More)
CONTEXT AND OBJECTIVE Recent studies have shown regional and population differences in semen characteristics. The objective was to establish reference values for semen analysis and to verify the effect that age, length of sexual abstinence, seasonality, smoking habits and coffee consumption have on fertile individuals' semen characteristics. DESIGN AND(More)
OBJECTIVES The objective of this study was to find HPV DNA incidence in women with CIN and normal women and in their respective partners, as well as the relation between the virus groups found in women with CIN or normal women and in their respective partners. METHODS Partners of 30 women with CIN at several grades and of 60 normal women were(More)
OBJECTIVE To evaluate the semen quality and hormonal levels in fertile men according to their level of cigarette smoking. SUBJECTS AND METHODS We evaluated 889 fertile men who came for a vasectomy for sterilization purposes. The men included 522 non-smokers, 143 mild smokers (<10 cigarettes/day), 154 moderate smokers (11-20/day), and 70 heavy smokers(More)
