[Vaginal candidiasis: etiology and sensitivity profile to antifungal agents in clinical use]

Candida vaginitis is one of the most frequent infection of the female genital tract with a high incidence. Approximately 75% of sexually active women suffer at least one episode of Candida vaginitis and 10% of them have recurrent episodes. Pregnancy, diabetes mellitus and antibiotic treatment are the most common predisposing factors, C. albicans is the etiologic agent most frequently found. The widespread reports of fluconazole resistance in Candida species and the selection of non Candida albicans prompted the study of species distribution of vulvovaginal candidiasis and their in vitro susceptibility against current antifungal agents. A total of 314 women with vaginal infection were studied. Yeasts were isolated from 104 patients with vulvovaginal candidiasis. The following species were identified: C. albicans 87.5%, C. glabrata 8.6% and 3.9% included C. krusei, C. famata, C. tropicalis and S. cerevisiae. The minimal inhibitory concentration (MIC) was determined for nystatin, isoconazole, fluconazole and ketoconazole, using a broth microdilution method based on NCCLS procedure. Although most of the isolates were C. albicans, the high percentage of C. glabrata recovered suggests the need to identify the yeasts isolated. Fluconazole resistant C. albicans were isolated in 13.46% of the cases. Thus, further studies are required to correlate the possible role of these strains in recurrent vulvovaginal candidiasis.

[Efficacy and tolerability of single-dose rosoxacin in the treatment of acute uncomplicated gonorrhea]

61 patients, male and female, with uncomplicated acute gonorrhea were given a single dose of 300 mg rosoxacin (2 capsules). 52 patients only completed clinical and laboratory controls. The drop-out rate for follow-up examinations was 14.8%. 98% of patients were cured. One patient failed to respond to treatment, and six had reinfection seven days later at follow-up control. Three of these were again treated with rosoxacin and cured. Among the side-effects, which were recorded in 24.4% of patients, dizziness was most prevalent (18.1%). Rosoxacin is particularly valuable in gonorrhea, given the single oral dose, the absence of resistance and the high percentage of efficacy.
