Views133PURPOSE: to verify the occurrence of colonization by Streptococcus agalactiae in pregnant women attended at the prenatal outpatient clinic of the Teaching Maternity Hospital of Rio de Janeiro University (UFRJ) and to evaluate the susceptibility of the isolates to antimicrobial agents. METHODS: a total of 167 pregnant women between the 32nd and 41st week of gestation, regardless of risk factors, attended at the antenatal clinic between February 2003 and February 2004, were evaluated. The vaginal/anal material, collected by the same swab, was inoculated in Todd-Hewitt broth to which nalidixic acid (15 µg/mL) and gentamicin (8 µg/mL) were added, with following subcultures onto sheep blood-agar. Identification was carried out observing colony morphology and beta-hemolysis type on blood-agar, catalase, cAMP, and serological tests. The antimicrobial susceptibility testing used agar diffusion and agar dilution methods. Statistical analysis was performed by the chi2 test with the level of significance set at p<0,05. RESULTS: the frequency of colonization was 19.2%, with no significant differences when age, number of gestations, number of abortions and the presence or absence of diabetes mellitus were compared (p>0.05). All 32 isolated strains were susceptible to penicillin, cefotaxime, ofloxacin, chloramphenicol, vancomycin and meropenem. Resistance to erythromycin and clindamycin was detected in 9.4 and 6.2% of the isolates, respectively. CONCLUSIONS: the relatively high incidence (19.2%) of colonization by S. agalactiae among the evaluated pregnant women and the recovery of antimicrobial resistant strains, especially those recommended in cases of penicillin allergy, emphasize the importance, for a correct prevention of neonatal infections, of detecting colonization at the end of pregnancy and evaluating antimicrobial susceptibility.

Views103See morePURPOSE: to estimate the prevalence of Family Health Program postpartum depression (PPD) and its association with minor mental disorders (MMD) among women attended in two (FHP) PSF units, in the city of São Paulo, and to identify risk factors associated with PPD. METHODS:a cross-sectional study with 70 postpartum women from two FHP units (Fazenda da Juta II and Jardim Sinhá), from October 2003 to February 2004. The following instruments were used: questionnaire with socio-demographical-economic data and obstetric and perinatal data; Self-Report Questionnaire 20 (SRQ-20), for screening of MMD, and Edinburgh Post-Natal Depression Scale (EPDS), for evaluation of PPD. To verify association between explanatory variables and PPD, Student's t test, chi2 or linear trend chi2 were utilized when indicated. To evaluate concordance between scales (EPDS and SRQ-20) kappa (kappa) coefficient correlation was used. RESULTS:the prevalence of PPD and MMD was 37.1%. Scales presented a good concordance (kappa=0.75). The explanatory variables age, ethnicity, years of education, profession, and marital status, besides partner's profession and years of education, familiar income, number of pregnancies, parity, miscarriage, number of alive children, premature deliveries, gestational age, type of delivery, planning of actual pregnancy, score of Apgar (first and five minutes), newborn sex and weight, and breastfeeding did not show significant statistical association. A greater perception of social support from the partner was associated with lower prevalence of PPD (p=0.03). CONCLUSION: because of its high prevalence and negative impact upon mother and child, it is worthwhile to sensitize health care professionals about the importance of PPD

Views111See morePURPOSE: to determine the prevalence of group B Streptococcus (GBS) in pregnant women in the third trimester of pregnancy and explore the factors potentially associated with colonization. METHODS: a sample of 273 pregnant women in the third trimester of pregnancy, from the prenatal care center in Southern Brasil, was investigated. Vaginal and anorectal samples were collected and innoculated in Todd-Hewitt selective broth supplemented with 10 µg/mL colistin and 15 µg/mL nalidixic acid and afterwards cultured on defibrinated sheep blood agar plates. All suspected colonies were submitted to the agglutination test for detection of the specific group B antigen. The Camp test was used for GBS identification in non-hemolytic varieties. Demographic, socioeconomic, reproductive, and clinico-obstetric data were also analyzed. Prevalence ratio (PR) was used as risk measurement. Confidence interval was considered significant at the level of 95% (alpha=0.05). RESULTS: prevalence of Streptococcus (GBS) colonization amounted to 21.6% (59), 9.9% (27) of pregnant women showing positivity in both sites; vaginal site colonization was found in 6.95% (19) of the women and 4.75% (13) of the samples showed positivity only in the anal site. GBS prevalence was slightly higher in pregnant women under 20 years, in those with less schooling and in primiparae and was twice as high among those who did not reported spontaneous abortion, but with no statistical significance. No difference was found in GBS prevalence according to the history of sexually transmittted diseases and tabagism. When analyzed together, the factors detected as potentially associated with colonization by GBS were: primiparae over 30 years (PR=1.55) and women with more than one sexual partner and increased frequency of sexual activity (p<0.05) (55,6 vs 20.5%; p<0.05). No difference regarding prevalence was found to exist in relation to the history of sexually transmitted diseases, previous spontaneous abortion and tabagism. CONCLUSION: these results confirm the need for routine collection for GBS culture from both sites (vaginal and anal) in all pregnant women in the third trimester of pregnancy.
