PURPOSE: To evaluate the perinatal factors that influence the incidence of necrotizing enterocolitis (NEC) in newborns infants (NBI) weighing less than 1,500 g. METHODS: A prospective study that analyzed all infants with birth weight (BW) less than 1,500 g born between January 2006 to December 2010 (n=183). They were divided into two groups, i.e. infants diagnosed with NEC (n=18) and infants without a diagnosis of NEC (n=165), which were compared in terms of perinatal factors that could influence the incidence of NEC. Mean data were compared by Student's t-test or nonparametric tests and percentages of categorical variables were compared by the χ² test. When the variables showed differences between groups, they were analyzed using logistic regression with the dependent variable as the presence of NEC. The statistical package used was SPSS 16.0 for Windows. RESULTS: The two groups were similar in terms of most of the clinical and demographic neonatal and maternal data, except for the presence of preeclampsia (PE), which was higher in patients whose children developed NEC (61.1 versus 35,6%). The presence of PE increased the chance of occurrence of NEC by 2.84 times (95%CI 1.0 - 7.7). CONCLUSION: The only factor that can interfere with the incidence of NEC in infants of very low birth weight was the presence of PE. Awareness of this fact can guide the perinatal team in providing more judicious care regarding the prevention of NEC in this specific population.

PURPOSE: To compare the degree of peripheral facial palsy of pregnant women and puerperae at admission and at discharge and to evaluate related factors. METHODS: Retrospective, cross-sectional study, with analysis of medical records of pregnant and postpartum women with facial palsy, over a period of 12 months, with application of a standardized protocol for patient evaluation and of the House-Brackmann scale on the occasion of the first visit and at discharge. RESULTS: Six patients were identified, mean age of 22.6 years. Five cases were classified as stage IV and one as stage II on the House-Brackmann scale, being two of them puerperae and four pregnant. All showed improvement on the House-Brackmann scale. CONCLUSION: The Bell's palsy has a good prognosis even in pregnant and postpartum women, being important to perform the correct treatment to reduce the sequelae in this group identified as more susceptible to peripheral facial palsy.

PURPOSE: To compare by transvaginal ultrasound the position of the intrauterine device (IUD) inside the uterine cavity, depending on the time of insertion, postpartum and post-abortion, and during the menstrual cycle. METHODS: Epidemiologic, observational and cross-sectional study carried out between February and July, 2013. A total of 290 women were included, 205 of them with insertion during the menstrual cycle and 85 during the postpartum and post-abortion periods. The independent variables were: age, parity, time of use, insertion time, number of returns to family planning, satisfaction with the method, wish to continue using the device, symptoms and complications. The dependent variable was the adequate position of the IUD inside the uterine cavity. The χ² test with Pearson's correction and the Fisher exact test were used for statistical analysis, with the level of significance set at 5%. RESULTS: The average age was 29.4 years and the average time of IUD use was 2.7 years; 39.3% of the women had symptoms associated with the method, the most frequent being menorrhagia (44.7%). The degree of satisfaction was 85% and 61.4% of the women returned two or more times for consultation about family planning. Age, parity and the position of the uterus in the pelvic cavity was not associated with a poor position of the IUD inside the uterine cavity (p>0.05). Insertion during the menstrual cycle was significantly more associated with a correct position of the IUD than postpartum and post-abortion insertion (p<0.028). CONCLUSION: Postpartum and post-abortion insertion showed worse results regarding the adequacy of IUD position, a fact that was not observed regarding age, parity or position of the uterus in the pelvic cavity.

PURPOSE: It was to determine the prevalence of Chlamydia trachomatis and the risk factors associated with infection in endocervical specimens from women seen in outpatient Obstetrics and Gynecology. METHODS: Samples of endocervical secretion of 200 women treated at the University Hospital of the Federal University of Rio Grande were analyzed for the presence of C. trachomatis by polymerase chain reaction (PCR) using primers that amplify CT05/CT06 281 base pairs of the main outer membrane protein of C. trachomatis. All participants completed a pre-coded and self-report questionnaire. Data were analyzed with the SPSS 17.0 software; for multivariate analysis it was used Poisson regression. RESULTS: Of the 200 women who were included in the study, the prevalence of infection with C. trachomatis was 11% (22 patients) and these 55 (27.5%) were positive for HPV. Risk factors associated with infection by C. trachomatis were: 8 years or less of schooling (p<0.001), family income below the poverty level (p=0.005), first intercourse at age 15 or less (p=0.04) and being a carrier of the virus HIV (p<0.001). After multivariate analysis, only the variables of schooling or less than eight years (PR 6.0; 95%CI 1.26 - 29.0; p=0.02) and presence of HIV (RP 14.1; 95%CI 3.4 - 57.5; p<0.001) remained statistically significant. CONCLUSIONS: The prevalence of C. trachomatis in endocervical specimens by PCR was 11%. The factors associated with a higher infection by C. trachomatis were lower education and being HIV positive.

PURPOSE: To evaluate sexual function in postmenopausal women diagnosed with metabolic syndrome. METHODS: Case-control study with 195 postmenopausal women (amenorrhea ≥1 year, FSH≥30 mIU/mL, aged 43 to 69 years) seen at the Department of Obstetrics and Gynecology, School of Medical Sciences of Santa Casa de São Paulo and in the Basic Units of the Family Health Program of São Paulo. Clinical data were collected, and body mass index and waist circumference were evaluated. Total cholesterol, HDL and LDL cholesterols, triglycerides, and fasting glucose were determined for biochemical analysis. We considered women to have the metabolic syndrome when they met three or more diagnostic criteria: waist circumference>88 cm and triglycerides ≥150 mg/dL; cholesterol HDL <50 mg/dL; blood pressure ≥130/85 mmHg, and fasting glucose ≥110 mg/dL. The participants were divided into Control Group (n=87) and Metabolic Syndrome Group (n=108). The Female Sexual Function Index (FSFI) was employed to assess the sexual function. RESULTS: Mean age was 54.0±4.7 years. The rate of sexual dysfunction was significantly higher in women with the metabolic syndrome than in the Control Group, both when considering FSFI <26.5 (90/108 [83.3%] versus 42/87 [48.2%], p<0.0001) and FSFI <23 (62/108 [57.4%] versus 16/87 [18.39%], p<0.001). The domains desire, arousal, lubrication, orgasm (p<0.001), and satisfaction (p=0.002) had lower scores in women with the metabolic syndrome. For the pain scores, there was no significant difference (p=0.57) between groups. All components of the metabolic syndrome diagnosis were associated with higher levels of sexual dysfunction (p<0.001). CONCLUSION: Postmenopausal women with metabolic syndrome present more frequently sexual dysfunction than those of the same age who do not have it.

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.

PURPOSE: To estimate the prevalence and identify the factors associated with delayed pap smear test of the cervix (carried out more than three years ago) among mothers with sons under two years of age, who attended the prenatal care. METHODS: Cross-sectional, population-based household survey. Women with sons under two years old, living in the northern area of the city of Juiz de Fora (MG), Brazil, were interviewed. Stratification and clustering were used in a complex sampling procedure. We applied a survey questionnaire to capture women's demographic and socioeconomic characteristics of women and information about prenatal and practices for preventing cancer of the cervix. For statistical analysis of the possible bivariate association of factors, we used χ² test and a logistic regression model with the explanatory variables that had a significance less than or equal to 0.05 in the bivariate analysis. RESULTS: We found a delayed test prevalence of 26.6% (95%CI 21.3 - 32.6), including women who were never submitted to the exam. The variables associated with the non-adherence to the examination within the stipulated time were: to be married (OR 0.5; 95%CI 0.2 - 0.9), and divorced/widowed (OR 0.1; 95%CI 0.02 - 0,8), having performed gynecological examination in prenatal care (OR 0.3; 95%CI 0.1 - 0.6) and number of prenatal visits (OR 0.09; 95%CI 0.03 - 0.25 for more than 11 visits), being all protection factors. CONCLUSIONS: The prevalence of adherence to Pap smear guidelines is slightly lower than the percentage recommended by the World Health Organization. Apart from that, the fact that the woman was submitted to the prenatal care did not guarantee the adherence to Pap smear frequency guidelines.

PURPOSE: To evaluate the clinical, ultrasonographic, biochemical and metabolic alterations of adolescents with polycystic ovary syndrome (PCOS). METHODS: Retrospective observational study conducted on 44 adolescents aged 12 to 19 years, diagnosed with PCOS according to the Rotterdam Consensus. Metabolic changes were assessed according to the recommendations of the International Diabetes Federation, considering: waist circumference (WC) >90th percentile (10-15 years of age) or >80 cm (age >16 years), fasting glucose >100 mg/dL, triglycerides >150 mg/dL, HDL <40 mg/dL, and blood pressure >Hg 130/85 mm. RESULTS: Mean age was 16.7±2.2 years and age at menarche was 11.8±1.4 years. The menstrual irregularity most frequently observed was amenorrhea (72.7%) followed by oligomenorrhea (27.3%); hirsutism was observed in 86.4% and acne in 56.8%. Polycystic ovaries were observed by ultrasound only in 27.3%. Mean BMI was 30.3±6.6 kg/m². According to BMI, 52.3% of adolescents were obese, 13.6% were overweight and 6.8% had a healthy weight. Increased waist circumference (63.6%, 28/44) and the reduction of HDL-C (34.1%, 15/44) were the metabolic changes most frequently observed. Increased triglycerides were observed in 27.3% (12/44) and increased blood pressure and impaired fasting glucose were found in 9.1% (4/44) and 4.5% (2/44) of cases, respectively. Acanthosis nigricans was observed in 52.3% and insulin resistance in 62.8% of the adolescents with PCOS. Metabolic syndrome was identified in six children (13.6%), all of them obese or overweight. CONCLUSION: In the adolescents with PCOS studied here, menstrual irregularity and hirsutism were the most common clinical manifestations, while the sonographic findings consistent with polycystic ovaries were less prevalent. Obesity associated with insulin resistance predisposes these adolescents to a higher frequency of metabolic disorders.
