PURPOSE: To evaluate the performance of a Brazilian reference curve of fundal height (FH) regarding its capacity of screening the deviations of volume of amniotic fluid using a Brazilian reference curve of amniotic fluid index (AFI) as gold standard. METHODS: This was a cross-sectional study evaluating 753 pregnant women receiving prenatal care at the public health services of João Pessoa (PB), from March to October 2006, who had a routine ultrasound exam scheduled for after 26 weeks of gestational age. Cases with diagnoses of twin pregnancy, intrauterine fetal death and major fetal malformations were excluded. Besides socio-demographic information, data regarding fundal height measured in a standard way, estimated fetal weight, AFI and gestational age at the time of the ultrasound exam were also collected. The capacity of the FH curve to predict deviations of the amniotic fluid volume was assessed using the Brazilian curve of AFI according to gestational age as the gold standard. For this purpose, sensitivity, specificity, positive and negative predictive values were estimated for different cut-off points. RESULTS: The measurement of FH identified 10.5% of women as having low FH possibly associated with oligohydramnios and 25.2% as having high FH possibly associated with polyhydramnios. Using a Brazilian reference curve of AFI, the FH was able to poorly predict the occurrence of oligohydramnios (sensitivity ranging from 37 to 28%) and to reasonably predict the occurrence of polyhydramnios (sensitivity ranging from 88 to 69%). CONCLUSIONS: The measurement of fundal height showed a poor performance for predicting oligohydramnios and a reasonable performance for predicting polyhydramnios. Its use for this purpose is then only supported in settings where the ultrasound exam is not easily or routinely available in order to help define priorities for cases that should have this exam performed.

PURPOSE: To determine the agreement between maternal perception of fetal movements and the movements recorded simultaneously by ultrasound in low-risk pregnancies. METHODS: Twenty pregnant women were evaluated with the following inclusion criteria: single pregnancy, alive fetus, maternal age between 18 and 35 years; between 36 and 40 weeks gestation; normal fetal morphology at ultrasound, and absence of maternal comorbidities. The pregnant women were evaluated for 10 minutes, during which cardiotocography was used to record fetal movements triggered with the event marker, with the paper speed set at 3 cm/min. At the same time, fetal movements were observed by ultrasonography. RESULTS: The kappa index for interobserver agreement analysis was 0.62, showing good agreement (95%CI 0.45 - 0.79). The intraclass correlation coefficient was 0.82 (95%CI 0.61 - 0.92). Analysis by the Bland & Altman graph indicated good agreement. A linear regression analysis showed a significant correlation between maternal perception (x) and ultrasound (y) observation (r²=0.71, p<0.001; equation: y=5.31+0.66x). CONCLUSIONS: The agreement between ultrasound and maternal perception of fetal movement is good, allowing the use of fetal movement counting in the assessment of fetal wellbeing.

PURPOSE: To evaluate the effectiveness and the safety of orally administered misoprostol in comparison to intravenously infused oxytocin for labor induction in term pregnant women. METHODS: Between 2008 and 2010, a total of 285 term pregnant women whom were candidate for vaginal delivery were assessed for eligibility to enter the study. Twenty five patients were excluded for different reasons; and 260 included women were randomly assigned to one of the two groups according to the method of treatment, misoprostol or oxytocin. The misoprostol group received 25 µg every 2 hours for up to 24 hours for induction. The oxytocin group received an infusion of 10 IU which was gradually increased. The time from induction to delivery and induction to the beginning of the active phase and successful inductions within 12, 18, and 24 hours were recorded. The trial is registered at irct.ir, number IRCT2012061910068N1. RESULTS: Failure of induction, leading to caesarean section was around 38.3% in the oxytocin group and significantly higher than that of the misoprostol group (20.3%) (p<0.001). Despite the more prevalent failure in the oxytocin group, the mean time intervals from induction to active phase and labor of this group were both significantly less than the misoprostol group (10.1±6.1 and 13.2±7.7 versus 12.9±5.4 and 15.6±5.1 hours respectively, both p-values were <0.05). Maternal and fetal complications were comparable between groups except gastrointestinal symptoms which were encountered more frequently in the misoprostol (10.9 versus 3.9%, p=0.03). CONCLUSIONS: Misoprostol is a safe and effective drug with low complications for the induction of labor. Failure is seen less with misoprostol and caesarean sections are less frequently indicated as compared to oxytocin.

PURPOSE: To ascertain the seroprevalence of human immunodeficiency virus (HIV), hepatitis B (HBV), toxoplasmosis and rubella infections in pregnant women in northwestern Paraná. METHODS: We conducted a retrospective study based on the results of serological screening during prenatal care of 1,534 patients during the first half of 2010. We included only results from the first prenatal exam and with a simultaneous search for IgG and IgM antibodies to rubella and toxoplasmosis. Serology was performed by microparticle enzyme immunoassay (MEIA). Data were analyzed statistically by the χ² test, with the level of significance set at 5%. RESULTS: HIV positivity was 0.3%, positivity of HBV serology (HbsAg) was 0.5%, reactivity to IgM antibodies to Toxoplasma gondii was 1.1%, and reactivity to IgG antibodies was 59.0%. For rubella, no patient was positive for IgM, and IgG reactivity was 99.6%. Data analysis showed no statistical association between seroprevalence and patient age, except for the frequency of anti-T. gondii IgG, which was higher in the 30 to 44 year age group. CONCLUSION: The prevalence of these infectious diseases in pregnant women from northwestern Paraná is comparable to that observed in other regions of Brazil.

PURPOSE: To evaluate the anthropometric characteristics of morbidity and mortality of premature newborns (NB) of hypertensive mothers according to the presence or absence of flow (DZ) or reverse (DR) diastolic flow in the dopplervelocimetry of the umbilical artery. METHODS: A prospective study was conducted on preterm newborns of pregnant women with hypertension between 25 and 33 weeks of gestational age, submitted to umbilical artery Doppler study during the five days before delivery. Delivery occurred at Hospital Regional da Asa Sul, Brasília - Federal District, between November 1st, 2009 and October 31st, 2010. The infants were stratified into two groups according to the results of Doppler velocimetry: Gdz/dr=absent end-diastolic velocity waveform or reversed end-diastolic velocity waveform, and Gn=normal Doppler velocimetry. Anthropometric measurements at birth, neonatal morbidity, and mortality were compared between the two groups. RESULTS: We studied 92 infants, as follows: Gdz/dr=52 infants and Gn=40 infants. In Gdz/dr, the incidence of infants small for gestational age was significantly greater, with a relative risk of 2.5 (95%CI 1.7 - 3.7). In Gdz/dr, infants remained on mechanical ventilation for a longer time: median 2 (0‒28) and Gn median 0.5 (0‒25) p=0.03. The need for oxygen at 28 days was higher in G dz/dr comparing to Gn (33 versus 10%; p=0.01). Neonatal mortality was higher in Gdz/dr compared to Gn (36 versus 10%; p=0.03; relative risk of 1.6; 95%CI 1.2‒2.2). Logistic regression showed that, with each 100 grams lower birth weight, the chance of death increased 6.7 times in G dz/dr (95%CI 2.0 - 11.3; p<0.01). CONCLUSION: In preterm infants of mothers with hypertensive changes in Doppler velocimetry of the umbilical artery, intrauterine growth restriction and neonatal prognosis are often worse, with a high risk of death related to birth weight.

PURPOSE: To understand the reproductive and sexual life of women treated for breast cancer. METHODS: A total of 139 women with a diagnosis made at least 6 months ago were interviewed after being randomly selected in a rehabilitation service. The interviews were carried out between 2006 and 2010. The inclusion criteria were: to have used a rehabilitation service between 2006 and 2010, to be a Unified Health System user, to have been a patient at a regional hospital and to be resident in the area of DRS XIII-Ribeirão Preto, state of São Paulo. The interviewees were visited at home where a face to face questionnaire regarding sociodemographic features and questions about the disease and reproductive and sexual life was administered. For the last one, the Female Sexual Function Index instrument was used. Data were analyzed statistically by the χ² test, Fisher exact test, Student's t test, multivariate analysis by logistic regression, factorial analysis and the Cronbach's alpha. RESULTS: Most patients had between 2 to 3 children and 80% used some contraceptive. About half of them had had sexual intercourse in the last month, 45.3% had interrupted sexual intercourse during treatment and 25.9% did not. There were reports of decreasing sexual activity, although half of the interviewees had re-started sexual life during the first six months after treatment. About half presented sexual dissatisfaction. An active sexual life is associated with being younger than 40 years of age and to have a partner. No association was found between active sexual life and diagnosis and types of treatment. CONCLUSION: Sexual activity of women treated for breast cancer is not associated with the treatments, but with age and with the opportunity of having sex.

PURPOSES: To determine the prevalence of irritable bowel syndrome (IBS) in women with chronic pelvic pain (CPP) and its associated features; to determine whether IBS and CPP constitute the same syndrome. METHODS: Cross-sectional population survey with systematic sequential sampling according to census districts in which 1470 women were interviewed with respect to the sample calculation. The participants resided in their own homes, were at least 14 years of age, experienced menarche and presented CPP according to the American College of Obstetrics and Gynaecology. The dependent variable was IBS based on Rome III criteria in women with CPP, and the following independent variables were possibly associated with IBS: age, schooling, duration of pain, sedentary lifestyle, migraine, depression, insomnia, back pain, dysmenorrhea, dyspareunia, depression, history of violence, and intestinal symptoms. The sample was subdivided into groups with and without IBS. After the descriptive analysis of the variables was performed, the respective frequencies were evaluated using GraphPad Prism 5 software. To evaluate the association between the dependent variable and the independent variables, the χ² test was used with a significance level of 5%. RESULTS: The prevalence of IBS in women with CPP was 19,5%. Pain duration (p=0.03), back pain (p=0.002), history of physical or sexual abuse (p=0.002), and intestinal complaints were more prevalent in the group with IBS and CPP. There was no difference between the groups regarding other criteria. CONCLUSION: The data confirmed the literature, identified several aspects that were shared between the pathologies and supported the hypothesis that both pathologies can constitute the same syndrome.
