PURPOSE: to analyze race, parity and presence of the progesterone receptor polymorphism, named PROGINS, as factors related to uterine leiomyoma occurrence in Brazilian women. METHODS: we carried out a case-control study, composed of 122 patients with the diagnosis of uterine fibroid and 125 women without the disease. After recording the clinical data, we collected biological material for DNA extraction, polymerase chain reaction and agarose gel electrophoresis in order to identify the presence of PROGINS polymorphism. Statistical analysis was performed using the non-parametric Mann-Whitney test or the chi2 test, depending on the studied variable. The risk for the occurrence of the disease was calculated by the logistic regression model, providing the odds ratio (OR). The adopted significance level was 5% (p<0.05) and the confidence interval was 95% (95% CI). RESULTS: we observed a higher prevalence of "non-white"women - mulatto and black - (50 vs 22.4%) and nulliparas (23.8 vs 11.2%) in the cases, while the progesterone receptor genotype was more often PROGINS positive - heterozygous or mutant homozygous - among the controls (21.6 vs 10.7%). The OR indicated an elevated risk for leiomyoma related to the "non-white"race (OR=3.46; 95% CI: 2.0-6.0) and the nulliparity (OR=3.30; 95% CI: 1.9-5.6), with reduction in the presence of PROGINS-positive genotypes (OR=0.43; 95% CI: 0.2-0.9). CONCLUSIONS: the "non-white"race and nulliparity were considered risk factors for the occurrence of uterine fibroid in the studied population, while PROGINS polymorphism showed to be a protective factor.

PURPOSE: to evaluate the contraceptive methods adopted by the public health system of Maringá County, Paraná, regarding the orientations for using them, indications, contraindications and reasons for interrupting these methods, as well as the profile of the female users. METHODS: transversal descriptive study, performed through 284 home interviews with women selected from the 62 groups of the Family Health Program, after their free and informed consent, and after the questionnaire had been approved by the Ethics in Research Committee involving human beings of the State University of Maringá (Universidade Estadual de Maringá - UEM). Before applying the questionnaires, they were pretested, focusing on the following sections: characterization of the interviewee, socioeconomical factors and contraceptive methods. Results were analyzed using the Statistical Package for the Social Sciences software 12.0 version. RESULTS: most women were white, married, between 35 and 49 years old, with high school education, working without salary, and from D and E economical classes. Of them, 22.5% were smokers and 4.9% alcohol users. Contraceptive pills were adopted by 50.3% of the women; condom by 28.1% and tubal ligature by 32%, following, in general, the health professional orientation. Reasons for interrupting the contraceptive methods were the wish to get pregnant, preference for a permanent method, and also because of the side effects of the pill. Smoking was the most prevalent risk factor for pill use. Only 35.9% of the interviewed women started using the pill after a previous medical visit, and almost in the same proportion, 33.6%, without visit before starting to use it. CONCLUSIONS: it was observed that the indications of the contraceptive method to be used, and the orientations accomplished by the health professionals were satisfactory, despite the high levels of tubal ligature and the detection of relative contraindications for pill users with more than 5 years of use.

PURPOSE: to evaluate the chronic effects of nelfinavir on body weight gain of pregnant albino rats and their concepts, as well as on the number of implantations, reabsorptions, fetuses, placentae, and maternal and fetal mortality. METHODS: fifty pregnant EPM-1 Wistar albino rats were randomly divided into five groups: two controls, Contr1 (control of stress) and Contr2 (drug vehicle control), and 3 experimental groups, Exp40, Exp120, Exp360, which received 40, 120 or 360 mg/kg per day of oral solution of nelfinavir, respectively. The drug and the vehicle (distilled water) were administered twice a day (12/12 h) by gavage from the first up to the 20th day of pregnancy. After sacrifice under deep anesthesia, the following parameters were evaluated: number of implantations and reabsorptions, the weight of fetuses and placentae, and the number of intrauterine deaths as well as inspection for major malformations. Data were evaluated by ANOVA followed by the Kruskal-Wallis multiple comparison test. RESULTS: body weight gain during pregnancy was normal for all the groups, and no significant differences were detected between them. ANOVA did not reveal any significant effect of nelfinavir on the studied parameters. The means of number of fetuses were: control = 9.7±0.50; nelfinavir-treated groups = 9.7±0.81. Regarding the means of number of placentae and implantations, controls = 9.7±0.50; nelfinavir-treated groups = 9.6±0.78. The mean fetal weights were as follows: controls = 4.04±0.50; nelfinavir-treated groups = 3.91±0.33 g. Finally, control placental weights averaged 0.64±0.02; nelfinavir-treated groups = 0.67±0.02 g. CONCLUSION: nelfinavir was well tolerated at all the administered doses; no damage was produced on the fetuses.

PURPOSE: to diagnose and treat diabetic pregnant women with antiphospholipid antibodies and to describe the gestational and perinatal results. METHODS: we evaluated 56 gestational and pregestational diabetic women who were attended at one specialized prenatal care unit, between July 2003 and March 2004. All of them had a blood test to quantify antiphospholipid antibodies. If positive, they were treated with heparin and aspirin at low doses and the usual treatment for diabetes. We calculated the prevalence and 95% confidence interval for all and also those for the pregestational ones. The characteristics of the pregnancies and the newborns are described. RESULTS: antiphospholipid antibodies prevalence among the diabetic pregnant women was 7% (95% CI - 0.1 to 13.9). Among pregestational diabetic women it was 12% (95% CI - 0.2 to 23.3). Among the diabetic women with antiphospholipid antibodies the duration of disease was five years or more. Maternal age in positive antiphospholipid antibodies diabetics ranged from 27 to 38 years; one was primiparous, another was secundiparous and two were multiparous. CONCLUSION: antiphospholipid antibodies prevalence in diabetic pregnant women was similar to that in the general population and lower than that of the pregestational diabetic women.

PURPOSE: to evaluate the relationship between S/A ratio in ductus venosus (DV) and perinatal outcomes in fetuses with brain sparing reflex. METHODS: the study was designed as an observational, sectional study with prospectively collected data. Forty-one fetuses with brain sparing reflex and gestational age between 25 and 33 weeks were studied between November 2002 and July 2005. The newborns were observed during the neonatal period in the intensive care unit of "Clínica Perinatal Laranjeiras" in order to find adverse outcomes. The study population was divided into two groups according to DV assessment. In the normal group all the fetuses with S/A ratio values of 3.6 or less were included, and in the abnormal group the fetuses with values of S/A ratio greater than 3.6. The statistical analysis was performed by the Mann-Whitney U-test, chi2 test and Fisher exact test. The results were considered significant when p<0.05. Gestational age, birth weight and Apgar score less than 7 at 5 min were evaluated. Perinatal outcome parameters were: intrauterine death, neonatal mortality, seizures, intraventricular hemorrhage, leukomalacia, need of surfactant, mechanical ventilation, myocardical failure, necrotizing enterocolitis, and length of stay in the intensive care unit. RESULTS: among the assessed 41 fetuses, 26 (63.4%) showed normal DV S/A ratio and the other 15 (36.6%) developed an abnormal DV S/A ratio (>3.6). There was no statistically signicant difference between the groups according to gestational age at delivery and Apgar <7. The only significant association was between abnormal DV S/A ratio and neonatal death (p=0.049; Fisher's exact test). No statistically significant association was observed for the other studied variables. CONCLUSIONS: our results suggest that abnormal DV blood flow detected by Doppler examination is not associated with adverse perinatal outcomes, except for neonatal mortality. This association may be considered statistically borderline (p=0.049). Excluding fetuses with birth weight less than 400 g, there was no other association between DV and neonatal mortality. The abnormal DV S/A ratio was not associated, in our study, with perinatal mortality in viable preterm fetuses.

PURPOSE: to identify maternal and perinatal factors related to neonates with birthweight >4,000 g. METHODS: cross-section cohort study with 411 consecutive cases of fetal macrosomia (FM) which occurred from March 1998 to March 2005. Data were compared to 7,349 cases of fetal birthweight >2,500 and <3,999 g which occurred in the same period. Maternal variables (maternal age, parity, diabetes, previous cesarean section, meconium-stained amniotic fluid, cephalopelvic disproportion, main cesarean section indications) and perinatal variables (birth injury, <7 1-min and 5-min Apgar score, fetal and early neonatal mortality range, need of neonatal intensive care unit) were analyzed. For statistical analysis the chi2 test with Yates correction and Student's t test were used with the level of significance set at 5%. RESULTS: FM was significantly associated with older mothers, more parous and <7 1-min Apgar score (p<0.05; OR=1.8; 95% CI: 1,4-2.5) and <7 5-min Apgar score (p<0,05; OR=2.3; 95% CI: 1.3-4,1), diabetes mellitus (p<0.05; OR=4.2; 95% CI: 2.7-6.4), meconium-stained amniotic fluid (p<0.02; OR=1.3; 95% CI: 1.0-1.7), need of neonatal intensive care unit (p<0,05; OR=2.0; 95% CI: 1.5-2.7), early neonatal mortality (p<0,05; OR = 2.7; 95% CI: 1.0-6.7), cesarean section (p < 0.05; OR = 2.03; 95% CI: 1,6-2,5) and cephalopelvic disproportion (p < 0.05;OR = 2.8; 95% CI: 1.6-4,8). There was no statistical difference between birth injury and fetal mortality range. In the FM group the main cesarean section indications were repeat cesarean sections (11.9%) and cephalopelvic disproportion (8.6%); in the normal birthweight group, repeat cesareans (8.3%) and fetal distress during labor (3.9%). CONCLUSIONS: in spite of the characteristic limitations of a retrospective evaluation, the analysis demonstrated which complications were associated with large fetal size, being useful in obstetric handling of patients with a diagnosis of extreme fetal growth. FM remains an obstetric problem of difficult solution, associated with important maternal and perinatal health problems, due to the significant observed rates of maternal and perinatal morbidity and mortality in developed and developing countries.

PURPOSE: postpartum anxiety (PPA) is highly prevalent and has important consequences on mother and newborn. The aim of the present study was to estimate the prevalence of PPA and its risk factors, in a sample of women attending a private setting. METHODS: a cross-sectional study was performed with 299 women, at a routine gynecological visit, from August 2000 to May 2003. The Spielberger State-Trait Anxiety Inventory (STAIT) and a questionnaire with sociodemographic data and obstetric data were used. Inclusion criteria were: women with no past or present history of depression, psychiatric treatment, alcohol or drug abuse and whose children were alive. The prevalences of PPA-trace and PPA-state, that evaluate characteristics of personality and transitory anxiety, respectively, were estimated with 95% confiance intervals (CI). Odds ratios and 95% CI were used to examine the association between PPA and exposure variables. Hypothesis testing was done by the chi2 test or chi2 test for linear trend, when categories were ordered. A p value < 0.05 was considered to be statistically significant. RESULTS: the prevalences of PPA-state and PPA-trace were 44.8% (CI 95%: 39.1 - 50.7) and 46.1% (CI 95%: 40.4 - 52.0, respectively). Formal agreement between scales was moderate (kappa = 0.55; p<0.001). By univariate analysis, lower mother income and presence of newborn complications were associated with PPA-state and PPA-trace. Lower maternal age and greater number of alive children were associated with PPA-trace and PPA-state, respectively. By multivariate analysis, PPA-trace and PPA-state were associated with higher mother income (OR:0.39; IC 95%: 0.21 - 0.74, p=0,005; OR:0.46; IC 95%: 0.24 - 0.87, p=0.02) and presence of complications in newborns (OR:2.15; IC 95%: 1.02 - 4.54, p=0.04) (OR:2.47; IC 95%: 1.16 - 5.25, p=0.02), respectively. PPA-trace was associated with greater maternal age (OR:0.34; IC 95%: 0.13 - 0.88, p=0.008), while PPA-state was associated with greater number of alive children (OR:1.82; IC 95%: 1.01 - 3.29, p=0.04). CONCLUSIONS: PPA was highly prevalent in this sample of women attending a private setting. Higher mother income and greater maternal age decrease the risk of AP, while presence of complications in newborns and greater number of alive children increase the risk.

METHODS: using a retrospective, descriptive, series of cases, with group comparison, the authors analyzed the data of 146 pregnant women, whose diagnosis of placental early aging (presence of grade II placenta before 32 gestational weeks or grade III, before 35 gestational weeks), and maternal-fetal conditions had been recorded in the medical charts at the "Maternidade Prof. Monteiro de Moraes", Recife, Pernambuco Brazil, from January 2000 to December 2002, where they had been attended as inpatients. The exclusion criteria were diagnoses of: premature amniorrhexis, multiple pregnancies, acute premature detachment of a normally located placenta, and fetal malformation. The clinical and obstetric complications were: hypertensive diseases, intrauterine growth restriction, changes of amniotic fluid volume, infections, maternal diabetes, falciform anemia, HIV seropositivity, drug addiction, renal lithiasis, epilepsy and bronchial asthma. In the medical records, 106 pregnant women were identified as having clinical and obstetric complications (Gwith group) and 40 as not having any of these complications (Gwithout group). For group comparisons, chi2 and exact Fisher statistical tests were used, with significance level of 0.05. RESULTS: Gwith group was associated with higher incidence of oligoamnion (27.3%), intrauterine growth restriction (44.3%) and caesarean section prior to labor (36.8%). Compared to Gwithout, the Gwith group was characterized by high incidence of: fetal death, prematurity (58.8% versus 40%), lower 5th minute Apgar index, birth weight less than 2.500g (67.9% versus 40%); small body size for gestational age (39.2% versus 10%) and more severe intercurrents events. CONCLUSIONS: perinatal prognosis does not depend upon placental early aging, but on clinical and obstetric maternal complications.
