RESUMEN
OBJECTIVE: To demonstrate the utility of fine needle aspiration biopsy in the diagnosis of prostatic tumors, basically carcinoma of the prostate. METHODS/RESULTS: The clinical records of 497 patients who underwent fine needle aspiration biopsy were reviewed. Age, skin color, clinical diagnosis by DRE, transrectal core biopsy, correlation between clinical and histological diagnosis, distribution according to type of adenocarcinoma, correlation between cytological and histological diagnosis, and complications were analyzed. Of the 497 patients, 162 had histological confirmation. Of these 162 patients, the Galen and Gambino statistical method was utilized in 132 which represented the true negatives and positives. Sensitivity was 86%, specificity 96%, positive predictive value 91%, negative predictive value 93%, and efficiency was 92%. The complication rate was low. CONCLUSIONS: Fine needle aspiration biopsy is a safe and efficient diagnostic method in prostatic tumors and causes minimal discomfort to the patient.

OBJECTIVES: To determine the incidence of asymptomatic bacteriuria in women consulting at our hospital and its relationship with other chronic diseases. METHODS: A cross-sectional study was conducted on 735 women who had consulted at our hospital from February to September, 1996. Urinary sediment, serial urine culture, serum urea and creatinine values were analyzed. Patient records were reviewed to obtain pertinent data for the study. RESULTS: The incidence of asymptomatic bacteriuria was 8%; 47.4% of the cases were women over 60 years of age. E. coli was identified as the causative organism in 77.9% of the urine cultures. Diabetes mellitus was the most frequent associated chronic disease (27.1%). The incidence of renal damage was not statistically significant and was not directly related with bacteriuria. CONCLUSIONS: We emphasize the importance of performing a urine culture when leukocyturia is detected. The incidence of asymptomatic bacteriuria increases with age. E. coli was the most frequent causative organism. Diabetes mellitus was the most frequent associated chronic disease. The incidence of renal damage was not statistically significant.

We present 35 patients diagnosed as suffering from Q fever during 1986, 1987, 1988. We establish a diagnosis criteria of complement titres greater than or equal to 1/64 or indirect immunofluorescent titres (IIT) 4 or more times higher than the initial, or a maintained title greater than or equal to 1/640 with specific IgM detected by positive IIT. 80% were male with a median age of 40.3 years. 85% had had contact with goats. 77% lived on the west side of the island 88.5% had increased GOT and GPT and only 5.7% had pneumonia. One patient previously healthy had ards, needing prolonged mechanical ventilation, and one patient had A-V blockade grade III which was treated successfully. We comment on the high incidence observed, which showed and endemic situation, and the epidemiological and clinical features of the disease.
