OBJECTIVE: to evaluate the presence of curved rods, suggesting Mobiluncus sp, and leukocytosis on Gram and Papanicolaou-stained vaginal smears in cases of bacterial vaginosis. METHODS: two hundred and five vaginal smears were studied by the Papanicolaou's method and other 205 vaginal smears, in the same patients, were evaluated by Gram staining. The diagnosis of bacterial vaginosis was made clinically by one of the authors (J.E.J.) using Amsel's criteria. In the Gram method stained smears the Nugent's score was calculated and the presence of curved rods was evaluated. In Papanicolaou's smears curved rods were searched as well the presence of leukocytes. The data were analyzed by Prism 3.0® with confidence interval of 95% using the Fisher exact test with modified Wald's method. RESULTS: on Pap smears the curved rods were present in 51.7% of the cases. The number of leukocytes varied, although the leukopenia was more frequent. In Gram-stained smears the curved rods were present in 46.8% of the cases and the Nugent's score was 8 in 48.3% of the cases. The finding of Mobiluncus sp in both methods occurred in 82%. When curved rods were observed leukocytosis occurred in 57.5% (p < 0.0001). In the same way, leukocytosis was more frequent in Nugent's scores 9 and 10. CONCLUSION: curved rods were observed in about 52% of bacterial vaginosis. Leukocytosis in Pap smears was more frequent when Mobiluncus sp were found with higher Nugent's scores.

O câncer de ovário é a neoplasia ginecológica mais letal e a sobrevida global é inferior a 40% em cinco anos. Isto ocorre principalmente porque a maioria das pacientes apresenta estadios avançados no momento do diagnóstico. Nestes casos as opções terapêuticas - citorredução e quimioterapia - são apenas parcialmente efetivas. Quando diagnosticado precocemente, por outro lado, a sobrevida em cinco anos é superior a 90% e a cirurgia geralmente é o único tratamento necessário. No entanto, em função da baixa prevalência do câncer de ovário na população, mesmo testes muito específicos produzem altas taxas de resultados falso-positivos e aumento de intervenções cirúrgicas para abordar massas anexiais assintomáticas. Com base nestes fatos, é essencial a busca de métodos e estratégias para se detectar estes tumores em estádios iniciais e ao mesmo tempo evitar intervenções desnecessárias. Neste artigo são revisadas as bases e as possíveis conseqüências de estratégias para a detecção precoce dos tumores ovarianos. São discutidos os principais métodos disponíveis e os resultados de alguns estudos com este objetivo.

To estimate the prevalence of bacterial vaginosis (BV), candidiasis and
trichomoniasis and compare the findings of physical examination of the vaginal
secretion with the microbiological diagnosis obtained by cytology study of a
vaginal smear using the Papanicolaou method.
A cross-sectional study of 302 women aged 20 to 87 years, interviewed and
submitted to a gynecology test for the evaluation of vaginal secretion and
collection of a cytology smear, from June 2012 to May 2013. Sensitivity analyses
were carried out and specificity, positive predictive value (PPV) and negative
predictive value (NPV) with their respective 95%CI were determined to assess the
accuracy of the characteristics of vaginal secretion in relation to the
microbiological diagnosis of the cytology smear . The kappa index (k) was used to
assess the degree of agreement between the clinical features of vaginal secretion
and the microbiological findings obtained by cytology.
The prevalence of BV, candidiasis and trichomoniasis was 25.5, 9.3 and 2.0%,
respectively. The sensitivity, specificity, PPV and NPV of the clinical
characteristics of vaginal secretion for the cytological diagnosis of BV were 74,
78.6, 54.3 and 89.9%, respectively. The sensitivity, specificity, PPV and the NPV
of the clinical characteristics of vaginal secretion for the cytological diagnosis
of candidiasis were 46.4, 86.2, 25.5 and 94%, respectively. The correlation
between the clinical evaluation of vaginal secretion and the microbiological
diagnosis of BV, candidiasis and trichomoniasis, assessed by the kappa index, was
0.47, 0.23 and 0.28, respectively.
The most common cause of abnormal vaginal secretion was BV. The clinical
evaluation of vaginal secretion presented amoderate to weak agreement with the
microbiological diagnosis, indicating the need for complementary investigation of
the clinical findings of abnormal vaginal secretion.

To identify risk factors for weight retention in women after childbirth.
This was a prospective observational study that followed for six months adult women who delivered at a tertiary center. Were applied a structured questionnaire before hospital discharge and at six weeks and six months after childbirth, through home visits. The outcome was weight retention after childbirth (if risk >7.5 kg). The variables analyzed were: age, skin color, working during pregnancy, income, education, marital status, age at menarche, maternal age at first birth, parity, mode of delivery, birth interval, pre-pregnancy weight, gestational weight gain, percent body fat, and nutritional status. Data were first analyzed by bivariate analysis between prevalence of weight retention at six months and several covariates (p<0.2). We then calculated the Odds Ratio (OR) and their respective gross confidence intervals of 95% (95%CI) and finally performed multivariate logistic regression to control for confounding factors and to estimate the OR and 95%CI.
The frequency of weight retention >7.5 kg by 6 months after delivery was 15%. In bivariate analysis, weight retention was associated with the following variables: age at menarche <12 years (OR=3.7; 95%CI1.1-13.2), gestational weight gain ≥16 kg (OR=5.8; 95%CI 1.8-18.6), percent body fat at baseline >30% (OR=5.0; 95%CI 1.1-23.6), and nutritional status by 6 weeks postpartum >25 kg/m2 (OR=7.7; 95%CI1.6-36.1). In multivariate analysis, only excessive gestational weight gain (OR=74.1; 95%CI 9.0-609.6) remained as a risk factor.
Excessive weight gain during pregnancy should receive special attention in prenatal care in view of its association with weight retention and excess weight in women after childbirth.

PURPOSE: to compare two screening tests for diabetes and their results to pregnancy outcomes. METHODS: in total, 279 pregnant women were submitted to two screening tests for gestational diabetes - fasting glycemia plus risk factors (FG + RF) and to the simplified glucose tolerance test (GTT50g). Screening by FG + RF consisted of the determination of fasting glycemia and anamnesis for the identification of risk factors on the occasion of the first prenatal visit. The GTT50g was performed between the 24th and the 28th week of pregnancy and consisted of the determination of plasma glycemia under fasting conditions and one hour after an oral overload with 50 g glucose. Positive and negative results were compared to pregnancy outcome. The dependent variables were: type of delivery, gestational age, weight and ponderal index at birth, Apgar indexes <7 in the 1st and 5th minutes, need for admission to the Intensive Care Unit (ICU), duration of hospitalization, and neonatal death. Data were analyzed statistically through the Students t-test, and the level of significance was set at 5%. RESULTS: only two of the perinatal variables studied were distinguished by the tests. An abnormal GTT50g was associated with a greater proportion of cesarean deliveries (58.7 versus 34.3%) and a positive FG + RF association was related to a higher rate of premature births (15.4 versus 5.4%). The other dependent variables did not differ among patients with positive and negative results of the two screening tests. CONCLUSIONS: despite the relation between prematurity and a positive FG + RF association, the increase of caesarean sections and the abnormal GTT50g, it would be a critical failure to accept these associations as definitive. Among others explanations, multiple intercurrent factors and the characteristics of the screening tests themselves should be considered.

Purpose: to evaluate retrospectively the obstetrical and perinatal aspects of multiple pregnancies with the death of one fetus. Methods: a retrospective study on 26 pregnant women with multiple pregnancies and death of one twin. A conservative approach was followed and the patients were followed-up clinically with blood clotting tests. Results: in 50% of the cases fetal death occurred between 20 and 32 weeks of pregnancy. The time between death and resolution of pregnancy ranged from 6 to 148 h. Death of the other twin occurred in two cases. In 15 cases, the surviving twin had a good course, with two of them presenting slight neurological sequelae. In the other nine cases the other twin died after birth. No pregnant woman developed coagulation disorders.
