PURPOSE: To investigate the etiology and the epidemiological profile of patients with vulvovaginal candidiasis (VVC) and predisposing factors. METHODS: Vaginal secretions were streaked in Sabouraud agar and yeast samples were isolated and identified by Polymerase Chain Reaction (PCR). Demographic and clinical data were obtained with a questionnaire. For statistical analysis, the Student's t-test, the χ² and Fischer tests were applied as needed using the Statistical Package for Social Sciences (SPSS) software, with the level of significance set at 5%. RESULTS: Sixty-nine patients aged from 15 to 52 years were evaluated. They were predominantly white (79.7%), with higher education (58%), married (56.5%) and sexually active (97.1%). Among them, 34.8% were pregnant, 7.2% diabetic, 1.4% seropositive for AIDS, and 36.2% were using oral contraceptives. Recent antibiotic therapy was mentioned by 13% of the patients, and antifungal or anti-trichomonas therapy was mentioned by 5.8 and 1.4% of the patients, respectively. Corticosteroid use was reported by 2.9% and antineoplastic by 1.4%. Vaginal discharge and itching were the main complaints (97.1 and 73.9%), followed by burning (63.8%) and erythema (63.8%). When present, the vaginal flow was predominantly white (88.1%) or lumpy (86.6%). The diagnosis was confirmed by culture in 55 (79.7%) patients, with mixed infections in 4 patients. The most prevalent species was C. albicans, followed by C. glabrata (one monoinfection and two mixed infections with C. albicans). C. lusitaniae and C. albicans were also identified in mixed infections (two patients). CONCLUSION: Despite the high culture positivity and clinical data characteristic of VVC, the symptoms were not pathognomonic. C. albicans is the most prevalent species, but other species are also involved in VVC etiology, such as the emergence of C. lusitaniae.

PURPOSE: To evaluate the epidemiological and clinical aspects of gynecological patients seeking care in the private and public health networks. METHODS: In this cross-sectional study we analyzed the records of 243 patients (122 public service patients and 121 private service ones), from January 2007 to January 2008. We excluded records of pregnant patients with vaginal bleeding, history of using vaginal creams or gels at intervals of less than 15 days and patients who had sexual intercourse within less than five days before their visit and with incomplete clinical data. Data were analyzed statistically using the Stata software, version 9.2, with a 5% level of significance. RESULTS: The mean age of the patients attending the public health service was 27±12 years-old and 25.9±10.4 years-old for patients attending the private health service, with no statistical difference between means (F=0.5 and p=0.4). Patients attending the public health service had lower education (p<0.001), they were preferentially housewives (p<0.001), began sexual life early, had a greater number of partners (p<0.001), of pregnancies (p<0.001) and of deliveries (p=0.004), and mainly used the condom as a contraceptive method (p=0.013). There was no statistical difference between groups regarding the history of sexual transmitted diseases, diagnosis of candidiasis, bacterial vaginosis, trichomoniasis, or neoplasia. CONCLUSIONS: Patients attending the public health service have a higher number of pregnancies and births. They are usually housewives with low educational level, their sex life begins early, and they have more partners. However, there was no difference between groups when evaluating breast diseases, gynecological infections, or cancer of the cervix, which suggests that socioeconomic status is not the only element in the determination of the disease and, therefore, other variables should be evaluated.

PURPOSE: to evaluate the frequency of HIV tests performed during prenatal care and rapid tests ordered for pregnant women admitted at the time of delivery. METHOD: this was a cross-sectional study with 711 pregnant women at delivery during the period from January to July 2010. Women admitted for clinical control and those that did not allow their clinical data to be included in the study were excluded. The χ² test or the Fisher's Exact test was used for comparison of the proportion in univariate analysis. All the variables with p<0.25 were included in the logistic regression model, called initial model. The analyses were carried out using the SPSS software, with the level of significance set at 5%. RESULTS: the mean age of the patients was 25.77±6.7 years and the maximum and minimum age was 44 and 12 years, respectively. The average gestational age at the time of attendance was 38.41±6.7 weeks. Of these patients, 96.3% (n=685) had prenatal care and 11.1% (n=79) received prenatal care at our facility. The average number of prenatal care visits was 6.85±2.88, but 28.1% had less than six visits. We identified 10 HIV-positive pregnant women (1.4%) and two patients were known to be HIV positive. The others (n=8) were screened at birth and therefore did not receive ARV prophylaxis during the prenatal period. Three patients were admitted during the expulsion period and also did not receive intrapartum antibiotic prophylaxis. However, all newborns were evaluated, with lactation being suppressed and artificial milk being used. CONCLUSIONS: despite the measures established by the Ministry of Health, there are still flaws in the approach to these patients. Only with the participation of managers and professionals involved in care it will be possible to correct the direct actions that enable the effective prevention of vertical transmission of HIV.

PURPOSE: to evaluate the expression of E-cadherin in cervical lesions of patients suffering from HIV infection. METHODS: we conducted a study with 77 patients with cervical HPV infection, 40 of them were HIV seropositive and 37 HIV seronegative who underwent colposcopy and a biopsy of the cervix. The material obtained by biopsy of the cervix was sent for histopathologic and immunohistochemical study. Sections were obtained and mounted on silanized slides and examined by an observer who was blind to patient serology. E-cadherin antibody, clone NHC-38 diluted 1:400 (DAKO) and the Novolink polymer system (Novocastra) were used. The expression of E-cadherin was determined on the epithelial cell membrane based on the extent of the stained area. The χ2 test with Yates correction or the Fisher's Exact test was used for comparison of the proportion in univariate analysis. All the variables with p<0.25 were included in the logistic regression model, called initial model. The analyses were carried out using the SPSS software, with the level of significance set at 5%. RESULTS: the expression of E-cadherin was observed in up to the internal 1/3 of the epithelium in 59.3% of cases and in up to 2/3 of the epithelium in 11.1% of cases, but in 29.6% of cases the expression was identified throughout the thickness of the epithelium in HIV-seronegative patients. In contrast, in HIV-seropositive patients, 45.9% showed expression up to 1/3 of the epithelium, 13.5% showed expression in up to 2/3 of the epithelium, and 40.5% showed expression throughout the thickness of the epithelium. E-cadherin expression did not differ between groups (p=0.5). However, the multivariate analysis identified a significant association between high-grade cervical injury and E-cadherin expression in 2/3 and 3/3 of the epithelium (p=0.001; χ2=36.9). CONCLUSIONS: the expression of E-cadherin in the epithelial cell membrane is not associated with infection by the human immunodeficiency virus, but with the degree of intraepithelial cervical injury.

PURPOSE: to evaluate association between CD4+ cell count and cervical intraepithelial lesion severity in HIV-infected women. METHODS: cross-sectional study of 87 HIV-infected patients which were confirmed by previous serologic examinations. All had cervical HPV diagnosed by polymerase chain reaction (PCR). All patients underwent anamnesis, physical examinations and colposcopy. Cervix biopsy was performed when indicated by colposcopical examination. Histopathological results followed Richart's classification, adapted by Wright, and CD4+ cell count and cervical intraepithelial lesion severity association was analysed by comparison of means using analysis using analysis of variance (ANOVA). RESULTS: among 60 biopsied women 24 were found (40.0%) with CIN I, eight (13.3%) with CIN II, three (5%) with CIN III, 14 (23.3%) with chronic cervicitis and 11 with cytopathic effect of HPV, without cell polarity loss. This corresponds to 35 (58.3%) women with intraepithelial lesion of low grade (CIN I + HPV) and 11 (18.3%) with intraepithelial lesion of high grade (CIN II + CIN III). There was no significant association between CD4+ cell count mean and cervical intraepithelial lesion severity (p=0.901). CONCLUSIONS: there was no association between CD4+ cell count and cervical intraepithelial lesion severity diagnosed by histopathological examination.
