@entity173 in @entity1 older than 60 years of age represent a serious morbidity linked to @entity170 that contributes to its mortality rates. Both genetic and environmental influences have been reported as important factors related to the epidemiology of @entity170 . Sobral, a city located in the northeast (equatorial zone) of Brazil (3 masculine S/40 masculine E) has 138,565 inhabitants, who are mostly white Portuguese and native Brazilian descendants. We evaluated the occurrence of @entity173 in Sobral between July 1996 and June 2000. This was a retrospective cohort-based study. Data were obtained from the medical records of the Santa @entity13389 de Sobral, which is the reference hospital in this area. All chart records of @entity1 aged >20 years with a diagnosis of femoral or @entity173 were revised. A total of 79 @entity174 were identified. Ten cases (12.6%) that occurred in @entity1 <50 years of age were excluded from further analysis. Sixty-nine cases (87.3%) occurred in @entity1 aged >50 years, comprising 19 (27.5%) @entity1 and 50 (72.4%) @entity1 . This gives an age-adjusted annual incidence rate of 5.59/10,000 per year in @entity1 and 12.4/10,000 per year in @entity1 , respectively, for @entity1 >50 years of age. Two @entity1 , aged 79 and 82, died 9 and 6 days, respectively, after hospital admission. The average time of hospitalization was 7.5 days (range 4-19 days). As expected, there was a significant rise in @entity173 in @entity1 >50 years old. Interestingly, the @entity173 rate in this population is considerably lower (around 4 times less) than the reported rates in white Caucasians.
