Mycobacterial infection, mainly by M. tuberculosis, has an important impact on kidney transplant recipients, particularly during the first year after surgery. Diagnosis often presents some difficulties, and a delay in treatment represents a determinant factor for the evolution, with a risk of death or permanent damage in renal function. Therefore, early diagnosis is mandatory. When the Mantoux reaction is positive, antituberculous prophylaxis seems advisable.

A semen sample has higher sensitivity than an EPS for the diagnosis of bacterial chronic prostatitis. In our clinical work-up, first-void urine and a semen culture are considered the only tests necessary to diagnose chronic prostatitis.

died. The different prognostic factors were assessed by univariate analysis with the Mann-Whitney U and Kendall A-B tests. RESULTSOf the evaluated 51 inpatients, eight died (16%) and 43 survived (84%). The median (range) age was 63 (17-85) years and the median time from the onset of the symptoms until the admission to the emergency room was 7.8 (1-60) days. The mean hospital stay was 33 (2-90) days and 17 patients were admitted to the intensive-care unit for a mean of 4.5 days. There was no statistically significant difference between the groups. Body surfaces involved were the scrotum in five patients (10%), the penis and scrotum in 11 (22%), the scrotum and perineum in 30 (59%) and the abdominal wall in five (10%). There was no statistically significant difference in the distribution in those who survived or died ( P = 0.131). The median age of 60 (17-81) years in the survivors was significantly lower than that of 73.5 (50-85) years in those who died ( P = 0.02). There was no significant difference ( P = 0.06) between the number of repeated debridements in the survivors (3.23) and those who died (5.25). The mean (range) FGSI score for survivors was 6.7 (0-14), vs 8.7 (6-13) for those who died ( P = 0.12). The only laboratory variables associated with death were serum bicarbonate ( P = 0.04) and serum sodium ( P = 0.02) levels. CONCLUSIONS
