Postoperative renal function evaluation, through RIFLE criteria, of elderly patients who underwent femur fracture surgery under spinal anesthesia.

Introduction: The postoperative acute renal failure (ARF) incidence in different kinds of surgery has rarely been studied. Age, cardiac dysfunction, previous renal dysfunction, intraoperative hypoperfusion, and use of nephrotoxic medications are mentioned as risk factors for ARF at the postoperative period. The postoperative ARF definition was based on the creatinine increase by the RIFLE classification (R = risk, I = injury, F = failure, L = loss, E = end stage), which corresponds to a 1.

Prevalence of prostate adenocarcinoma according to race in an university hospital.

Objectives: To determine the prevalence of prostate cancer and to assess potential associations between race and prostate adenocarcinoma according to age in patients followed in an outpatient service of general urology in an university hospital.

Materials And Methods: Retrospective study of men aged from 40 to 79 years, followed during the period from 1999 to 2001. Patients were classified according to race in White, Mulatto and Black.

Acute renal failure after coronary artery bypass surgery with extracorporeal circulation -- incidence, risk factors, and mortality.

Objective: To identify the incidence, risk factors, and mortality of acute renal failure (ARF) in patients undergoing myocardial coronary artery bypass surgery with extracorporeal circulation.

Methods: All patients undergoing myocardial coronary artery bypass surgery were prospectively studied, and their clinical and laboratory variables were assessed using uni- and multivariate analysis (logistic regression).

Results: Acute renal failure occurred in 16.

[Influence of hypertension on the incidence of end-stage renal disease in negroes and mulattoes with glomerulonephritis].

Objective: To assess whether hypertension diagnosed during the first two months of follow-up is associated with the incidence of end-stage renal disease (ESRD) in negroes and mulattoes with glomerulonephritis after taking into account age, gender and the histological diagnosis.

Methods: A retrospective cohort study based on a sample of' 120 negro and mulatto patients with glomerulonephritis, 26 with membranoproliferative glomerulonephritis (MPGN), 58 with focal segmental glomerulosclerosis (FSG) and 36 with other types of glomerulonephritis (OTGN). Hypertension was considered present if antihypertensive treatment was used, in adults (age >18 years) with a mean of the three first systolic blood pressures of 140 mmHg or a mean of the corresponding diastolic blood pressure of 90 mm Hg or greater.
