, , , , , , , To compare the type of management (active versus expectant) for preterm premature rupture of membranes (PPROM) between 34 and 36 + 6 weeks of gestation and the associated adverse perinatal outcomes in 2 tertiary hospitals in the southeast of Brazil.
In the present retrospective cohort study, data were obtained by reviewing the medical records of patients admitted to two tertiary centers with different protocols for PPROM management. The participants were divided into two groups based on PPROM management: group I (active) and group II (expectant). For statistical analysis, the Student t-test, the chi-squared test, and binary logistic regression were used.
Of the 118 participants included, 78 underwent active (group I) and 40 expectant management (group II). Compared with group II, group I had significantly lower mean amniotic fluid index (5.5 versus 11.3 cm, p = 0.002), polymerase chain reaction at admission (1.5 versus 5.2 mg/dl, p = 0.002), time of prophylactic antibiotics (5.4 versus 18.4 hours, p < 0.001), latency time (20.9 versus 33.6 hours, p = 0.001), and gestational age at delivery (36.5 versus 37.2 weeks, p = 0.025). There were no significant associations between the groups and the presence of adverse perinatal outcomes. Gestational age at diagnosis was the only significant predictor of adverse composite outcome (x2 [1] = 3.1, p = 0.0001, R2 Nagelkerke = 0.138).
There was no association between active versus expectant management in pregnant women with PPROM between 34 and 36 + 6 weeks of gestation and adverse perinatal outcomes.

The present study assessed epidemiological and obstetrical data from pregnant women with syphilis at the Hospital de Clínicas of the Universidade Federal do Triângulo Mineiro (UFTM, in the Portuguese acronym), describing this disease during pregnancy and its vertical transmission for future healthcare actions.
Records from pregnant women who had been admitted to the Obstetrics Department of the Hospital de Clínicas of the UFTM and were diagnosed with syphilis between 2007 and 2016 were reviewed. A standardized form was used to collect epidemiological, obstetric data and outcomes of congenital infection. The present research has been authorized by the Ethics Committee of the institution.
There were 268 women diagnosed with syphilis, with an average age of 23.6 years old. The majority of the patients were from Uberaba. Inadequate prenatal care was observed in 37.9% of the pregnant women. Only 34.2% of the patients completed the treatment according to the guidelines issued by the Ministry of Health of Brazil, and 19.8% of the partners of the patients underwent adequate syphilis treatment; 37 (13.8%) couples (patients and partners) underwent correct treatment. Regarding the obstetric outcomes, 4 (1.5%) patients had a miscarriage and 8 (3.4%) had fetal losses (from the fetal loss group, 7 had no adequate treatment); 61 (25.9%) patients had premature births - this prematurity has been significantly correlated to inadequate or incomplete treatment in 49 (27.9%) patients, compared with 12 (13.0%) patients with premature births and adequate treatment (p = 0.006). The average live newborn weight was 2,840 g; 25.3% had a birth weight < 2,500 g; 74.2% had congenital syphilis, a data with heavy correlation to inadequate or incomplete prenatal care, prematurity, and low birth weight.
Public awareness policies on adequate prenatal care, intensification of serological screening, and early treatment of syphilis are needed, considering the rise of cases diagnosed during gestation and its potentially preventable deleterious consequences related to congenital transmission.

PURPOSE: To identify genetic polymorphisms of endothelial growth factor (VEGF), positions +936C/T and -2578C/A, in women with pre-eclampsia. METHODS: This was a cross-sectional study conducted on 80 women divided into two groups: pre-eclampsia and control. The sample was characterized using a pre-structured interview and data transcribed from the medical records. DNA extraction, amplification of sequences by the Polymerase Chain Reaction (PCR) with specific primers and polymorphism analysis of Restriction Fragment Length Polymorphism (RFLP) were performed to identify polymorphisms. The statistical analysis was performedin a descriptive manner and using the 
test. The multiple logistic regression model was used to determine the effect of polymorphisms on pre-eclampsia. RESULTS:Ahigher frequency of the T allele of theVEGF +936C/T polymorphism was observedin patients with pre-eclampsia, but with no significant difference. The presence of allele A of the VEGF -2578C/A was significantly higher in the control group. CONCLUSIONS:No significant association was observed between VEGF +936C/Tpolymorphism andpre-eclampsia. For the VEGF -2578C/A polymorphism a significant differencewas observed between thecontrol and pre-eclampsia group, with allele A being the most frequent in the control, suggesting the possibility that carriers of allele A have lower susceptibility to the development of pre-eclampsia.

Purpose: to evaluate the results of a rapid diagnostic test for HIV-1 infection made available by the Health Ministry for the identification of pregnant women contaminated by this virus. Methods: we evaluated prospectively 443 pregnant women with no prenatal serologic anti-HIV test seen at the Department of Gynecology and Obstetrics of the Faculty of Medicine of Ribeirão Preto, University of São Paulo, from February to June, 2000. Samples from these patients were submitted to the rapid immunochromatographic test, which was compared with ELISA and submitted to a confirmatory agglutination test. Results: among the 443 pregnant women submitted to the rapid test (20.1% of the deliveries performed during the study period), 16 showed positive results (3.6%). No sample with a negative result by the rapid test was positive by ELISA. However, of the 16 samples that were positive by the rapid test, two were negative by the confirmatory tests. Thus, the rapid test showed 100.0% sensitivity, 99.5% specificity, 87.5% positive predictive value, and 100.0% negative predictive value. Conclusions: the results obtained by evaluation of the test for a rapid diagnosis of HIV-1 infection in pregnant women revealed sensitivity, specificity and predictive values that qualify it as an extremely important resource for the indication of measures that will reduce perinatal transmission of this virus.

Purpose: to evaluate the seroprevalence of infection caused by HSV-2 among pregnant women delivering at the University Hospital, Faculty of Medicine of Ribeirão Preto (UHFMRP-USP) and to standardize laboratory techniques to be used for this purpose. Methods: a total of 1500 blood samples from pregnant women seen at the Obstetric Center of the Department of Gynecology and Obstetrics, UHFMRP-USP, between January 1st and October 31st, 1996, were evaluated. To determine the real prevalence of HSV-2 infection, the ELISA technique was standardized but, during its initial use, it was found to be not sufficiently specific to discriminate between the two viral types (75%). Thus, it became necessary to use a more specific technique and the method standardized for this purpose was Western blot, which can detect the specific HSV-2 viral protein. Results: the seroprevalence of herpes infection induced by the two viral types (HSV-1 and HSV-2) was 94.5% when ELISA was used. With the use of Western blot, a 32% seroprevalence of HSV-2 infection was detected in the studied population, whether symptomatic or asymptomatic. Conclusion: a high prevalence of carrier status for HSV-2 and HSV-1 infection was detected, as shown by the high rate of positivity for antibodies against this virus. ELISA did not show sufficient specificity to discriminate between HSV-2 and HSV-1 antibodies.
