To evaluate the compliance and degree of satisfaction of nulligravida (has not given birth) and parous (had already given birth) women who are using intrauterine devices (IUDs).
A cross-sectional cohort study was conducted comparing nulligravida and parous women who had had an IUD inserted between July 2009 and November 2011. A total of 84 nulligravida women and 73 parous women were included. Interviews were conducted with women who agreed to participate through telephone contact. Statistical analysis was performed with Student s t-test and Mann-Whitney test for numeric variables; Pearson s chi-square test to test associations; and, whenever pertinent, Fisher s exact test for categorical variables. A survival curve was constructed to estimate the likelihood of each woman continuing the use of the IUD. A significance level of 5% was established.
When compared with parous women, nulligravida women had a higher education level (median: 12 vs. 10 years). No statistically significant differences were found between the nulligravida and parous women with respect to information on the use of the IUD, prior use of other contraceptive methods, the reason for having chosen the IUD as the current contraceptive method, reasons for discontinuing the use and adverse effects, compliance, and degree of satisfaction. The two groups did not show any difference in terms of continued use of the IUD (p = 0.4).
There was no difference in compliance or the degree of satisfaction or continued use of IUDs between nulligravida and parous women, suggesting that IUD use may be recommended for women who have never been pregnant.

PURPOSE: To describe the maternal and perinatal outcomes after the use of 12.5 µg of sublingual misoprostol for labor induction in women with term pregnancy and a live fetus. METHODS: We conducted a multicenter, open and non-randomized clinical trial during the period from July to December 2009. We included 30 pregnant women with an indication for labor induction at term, carrying a live fetus, with a Bishop score of six or less, cephalic presentation, estimated fetal weight of less than 4,000 g and an amniotic fluid index greater than five. We excluded women with a previous uterine scar, non-reassuring fetal status, congenital anomalies, multiple pregnancy, intrauterine growth restriction, genital bleeding, and contraindications of vaginal delivery. A tablet of 12.5 µg sublingual misoprostol was administered every six hours, until the beginning of labor, with the maximum of eight doses. RESULTS: Labor was successfully induced in 90% of pregnant women. The mean interval between the first dose and the onset of uterine contractions and delivery was 14.3±11.7 hours and 25.4±13 hours, respectively. The frequency of vaginal delivery was 60%. Uterine tachysystole occurred in two pregnant women, being reversed in both cases without the need for cesarean section. Meconium-stained amniotic fluid was observed in four patients, and an Apgar score of less than 7 at five minutes in only one newborn. CONCLUSION: Maternal and perinatal outcomes were favorable after induction of labor with sublingual misoprostol at a dose of 12.5 µg every six hours. However, controlled trials are needed to compare this regimen with other doses and routes of administration.

PURPOSE: to test effectiveness and safety of the oral administration of a new misoprostol formulation in titrated doses for the induction of delivery of a live fetus at term. METHODS: an open pilot multicenter, non-randomized clinical trial was conducted from July to December 2008. A total of 30 patients with indications for induction of labor were included. The patients had a live fetus, Bishop score <6, vertex presentation, fetal weight <4,000g estimated by ultrasonography and amniotic fluid index >5. Exclusion criteria were previous uterine scar, non-reassuring fetal heart rate tracing, multiple pregnancy, fetal growth restriction, genital hemorrhage and presence of genital tumors, ulcerations or malformations. An initial dose of 20µg/hour of the oral misoprostol solution was used in the first 6 hours, and was increased progressively to 20µg/hour every 6 hours if labor did not start, up to a maximum dose of 80µg/h in the first 24 hours, maintained for additional 24 hours if necessary. RESULTS: labor was satisfactorily induced in 96.7% of patients. The interval between the first dose and the beginning of uterine contractions was 3.8±1.8 hours. The interval between the initial dose and delivery varied from 6 to 24 hours. The frequency of vaginal delivery was 80% (24 cases). Most of the patients (60%; n=18) initiated labor with a dose of 20mg/hour. Tachysystole occurred in 13.3% of women and meconium-stained fluid was detected in 20% of cases. There were two cases of Apgar scores <7 in the first minute and no Apgar score <7 in the fifth minute. CONCLUSIONS: the oral solution of misoprostol was effective and safe for the induction of labor. However, further randomized controlled trials are needed to compare this new formulation with misoprostol administered by the vaginal route.

PURPOSE: To determine perinatal outcomes and factors associated with fetal brain sparing effect diagnosed by Doppler flow velocimetry in patients with arterial hypertension. METHODS: We performed a cross-sectional retrospective study including 129 pregnant women with arterial hypertension and submitted to Doppler flow velocimetry, within fifteen days before delivery. Women with multiple pregnancies, fetal malformations, genital bleeding, placenta praevia, premature rupture of membranes, smoking, illicit drug use and chronic diseases were excluded. We analyzed the biological, socio-demographic and obstetric characteristics, as well the perinatal outcomes. To determine the association between variables, we used the χ² test, Fisher's exact test and Student's t-test. Multiple logistic regression analysis was performed to determine the factors associated with fetal centralization. RESULTS: Pre-eclampsia was the most frequent hypertensive disorder (53.5%) and fetal brain sparing effect was observed in 24.0% of fetuses. The prenatal factors associated with fetal brain sparing were the persistence of bilateral protodiastolic notches in uterine arteries (OR 3.6; 95%CI 1.4 - 9.4; p=0.009) and intrauterine growth restriction (IUGR) (OR 3.3; 95%CI 1.2 - 9.3; p=0.02). The perinatal outcomes associated with fetal brain sparing were gestational age <32 weeks, small for gestational age (SGA) infants, birth weight <2,500 g and perinatal death. There was no association with other maternal or neonatal variables. CONCLUSIONS: The main factors associated with fetal brain sparing were persistence of uterine arteries notches, IUGR, and increased frequency of adverse perinatal outcomes.

A good quality prenatal assistance is essential to warrant perinatal and maternal health. Nowadays, due to the evolution of diagnostic methods and the change in illness prevalence, such as the increase in diabetes and sexually transmitted diseases, several propedeutic procedures are available. This introduces further difficulty for clinicians to select the most adequate procedures and when to apply them during gestation, assuring the best results for both mother and infant. The present review aimed at evaluating the main prenatal routine tests on the basis of the best scientific evidence presently available.

PURPOSE: to evaluate the agreement between conventional cytology using the Papanicolaou test, repeated at the time of colposcopy, with colposcopic and histopathological findings. METHODS: the study was carried out at the central public health laboratory of the state of Pernambuco between January and July, 2008, involving 397 women referred for colposcopic evaluation following an abnormal cervical smear test. Cytology was repeated at the time of colposcopy using conventional method, with particular attention being paid to the presence of abnormal colposcopic findings. The nomenclature used for cytology was the 2001 Bethesda system terminology, while that used for histology was the World Health Organization 1994 classification. Cytology performed at the time of colposcopy was compared with colposcopy and with histopathology obtained by colposcopy-directed biopsy. The Kappa coefficient was used to evaluate the agreement between methods, as well as the χ2 test, with the level of significance set at 5%. RESULTS: poor agreement was found between cytology performed at the time of colposcopy and colposcopic findings (K=0.33; 95%CI=0.21-0.45) and between colposcopy and histopathology (K=0.35; 95%CI=0.39-0.51). Cytology performed at the time of colposcopy compared with histopathology revealed a Kappa of 0.41 (95%CI=0.29-0.530), which was considered to reflect moderate agreement. CONCLUSIONS: agreement was better between cytology and histopathology than between colposcopy and cytology or between colposcopy and histopathology.

PURPOSE: to identify factors associated with gestation in adolescence in a State of the northeast of Brazil. METHODS: a case-control study in the ratio of one 10 to 19-year-old adolescent (case) for two 20 to 35-year-old women (controls), with a total of 168 cases and 337 controls. The variables analyzed were: schooling, marital status, origin, family income per capita in Brazilian currency, paid job, mother's schooling, and presence of adolescent's father at home. Reproductive variables such as age at the first intercourse, mother's history of adolescence pregnancy, gynecological appointments before the pregnancy, knowledge, access and use of contraceptive methods were also included in the analysis. RESULTS: the following variables were associated with gestation in adolescence: schooling lower than eight years, lack of a regular mate, and maternal history of adolescence gestation. Also, the age at the first intercourse was significantly lower among the adolescents and that they had a lower rate of gynecological appointments. Knowledge of hormonal methods and access to contraceptive methods were also less frequent among the adolescents. After the multiple logistic regression analysis, risk factors for pregnancy at adolescence were: low schooling (OR=2.3; CI95%=1.3-3.8), age at the first intercourse lower than 15 years old (OR=3.6; CI95%=2.2-5.7), history of maternal pregnancy at adolescence (OR=2.6; CI95%=1.7-3.4). The history of previous gynecological appointments (OR=0.3; CI95%=0.2-0.4) and the use of hormonal methods (OR=0.6; CI95%=0.4-0.9) were protecting variables. CONCLUSIONS: the main factors associated with pregnancy in adolescence were: the adolescent's low schooling, maternal history of adolescence gestation, lack of previous gynecological appointments and lack of access to contraceptive methods.
