RESUMO

Given the devastating mortality and morbidity associated with HIV/AIDS, many potential prevention measures against HIV infection continue to be explored. Most prevention methods are in the realm of sexual behavior change. However, of all aspects of human behavior, it is sexual behavior that is least amenable to change. Newer and simpler interventions are therefore required. Male circumcision, the surgical removal of some or all of the foreskin [or prepuce] from the penis is one of the new ways being promoted as a preventive measure. This paper reviews the scientific basis and evidence for the efficacy of male circumcision within the context of the global challenges involved. We reviewed articles with emphasis on male circumcision and HIV/AIDS transmission. Published abstracts of presentations at international scientific meetings were also reviewed. Current epidemiological evidence seems to support the promotion of male circumcision for HIV prevention, especially in populations with high HIV prevalence and low circumcision rates. And the last three randomized control trials strengthen the case for applied research studies to demonstrate that safe male circumcision is protective at the population level, particularly as ideal and well-resourced conditions of a randomized trial are often not replicated in other service delivery settings. Ethically and culturally-responsive strategies in promoting circumcision in a culturally heterogeneous world need to be developed, too. Male circumcision should also be viewed as a complementary measure along with other proven approaches to turn the epidemic around

RESUMO

Prostate cancer is an important cause of morbidity and mortality worldwide. While the predisposing factors are not fully understood, African descent is an important risk factor, and prostate cancer has become the number-one cancer in Nigerian men. This was a retrospective study of the correlation between serum prostate specific antigen [PSA] and Gleason grade and score in patients of Nigerian descent. The University College Hospital [UCH] Ibadan Cancer Registry was used to identify and quantify the incidence of prostate cancers occurring between 1998 and 2000. The histological slides of appropriate cases were reviewed to confi rm the Gleason grade and score. The serum PSA values were retrieved from the patients' case notes and laboratory files. The data obtained were subjected to statistical analysis to look for associations and correlations. The study included 67 men with prostate adenocarcinoma and PSA measurements who were diagnosed and treated at the UCH Ibadan between January 1998 and December 2000. There was a positive correlation between serum PSA and Gleason grade, as well as between serum PSA and Gleason score in our cohort of Nigerian African men with prostate cancer. PSA levels were significantly lower in patients with stage B disease than in patients with stage D disease. Serum PSA is signifi cantly higher in metastatic than in localized disease. Further studies are necessary to determine biomarkers that complement serum PSA and the Gleason grading system in the prognostication of prostate cancer in African patients
