Relationship of age to outcome and clinicopathologic findings in men submitted to radical prostatectomy

OBJECTIVE: It is controversial whether age is associated with higher grade and worse outcome. Some studies have not found age to be related to outcome nor younger age to be associated with better response to therapy. MATERIALS AND METHODS: The study population consisted of 27 patients aged 55 years or younger and 173 patients 56 years or older submitted to radical prostatectomy. The variables studied were preoperative PSA, time to PSA progression following radical prostatectomy and pathologic findings in surgical specimens: Gleason score, Gleason predominant grade, positive surgical margins, tumor extent, extraprostatic extension (pT3a), and seminal vesicle invasion (pT3b). RESULTS: Comparing patients aged 55 years or younger and 56 years or older, there was no statistically significant difference for all variables studied: preoperative PSA (p = 0.4417), Gleason score (p = 0.3934), Gleason predominant grade (p = 0.2653), tumor extent (p = 0.1190), positive surgical margins (p = 0.8335), extraprostatic extension (p = 0.3447) and seminal vesicle invasion (p > 0.9999). During the study period, 44 patients (22 percent) developed PSA progression. No difference was found in the time to biochemical progression between men aged 55 years or younger and 56 years or older. CONCLUSION: Our findings suggest that age alone do not influence the biological aggressiveness of prostate cancer.

Whipple's disease with neurological manifestions: case report

A doença de Whipple (DW) é distúrbio multissistêmico raro causado pelo bacilo Tropheryma whipplei. O envolvimento do sistema nervoso central é um aspecto clássico da doença, sendo observado em 20 a 40% dos pacientes. Relatamos o caso de homem de 62 anos com DW que desenvolveu manifestações neurológicas durante sua evolução, com o objetivo de discutir os sinais e sintomas mais comuns e destacar os critérios diagnósticos e propostas terapêuticas mais recentes.
