Objective: to evaluate the diagnosis, characteristics of pregnancy, maternal complications and perinatal outcome in cases of congenital hydrocephalus, and to associate them with pregnancy and delivery variables. Methods: 116 pregnancies with this diagnosis were evaluated before or after delivery, 112 of them occurring at the Maternity ward of CAISM/UNICAMP during the period between 1986 and 1995. For perinatal variables, complete data of 82 newborns were used. For data analysis, distributions and means were calculated and c² and Fisher exact tests were applied. Results: generally the diagnosis was made before delivery, confirmed by ultrasound and the delivery was through a cesarean section in cases. Cephalocentesis was performed in 11 cases and complications were more frequent in vaginal delivery than cesarean section. Low Apgar scores were more frequent among newborn babies delivered vaginally. Congenital hydrocephalus was also associated with important neonatal and perinatal morbidity and mortality, with other malformations, and a very low number of children without sequelae. Conclusions: the evaluation of these factors may be of great value for the obstetrician who is following pregnant women with this fetal malformation. This could better support the decisions that, although medical and ethical, should take into account the risk-benefit ratio of measures to be taken.

PURPOSE: To describe the prevalence of maternal mortality at a tertiary care hospital and to assessits preventability. METHODS: This study, through the analysis of maternal deaths that occurred during the period from 1999 to 2010 at a reference in Campinas - Brazil, CAISM/ UNICAMP, discusses some of the factors associated with the main causes of death and some structural problems of structure of the health services. It is a retrospective descriptive study with evaluation of sociodemographic variables and the medical and obstetric history of women, and the causes of death. RESULTS: The majority of maternal deaths occurred due to direct obstetric (45%) and avoidable (36%) causes, in women with preterm gestation, who delivered by cesarean section (56%) and received various management procedures, including blood transfusion, ICU admission and need for laparotomy and/or hysterectomy. The hospital transfer was associated with the predominance of direct obstetric (19 versus 6, p=0.02) and avoidable causes (22 versus 9, p=0.01). CONCLUSIONS: We conclude that, despite current advances in Obstetrics, infections and hypertensive disorders are still the predominant causes of maternal mortality. We observed an increase of clinical-surgical conditions and neoplasms as causes of death among women during pregnancy.

PURPOSE: to evaluate the correlation between the estimated fetal weight (EFW) by ultrasonography and the neonatal weight (NW), as well as the EFW's capacity to predict changes in NW among pregnant women in João Pessoa, Paraíba, Brazil. METHODS: a diagnostic validation study, including 122 pregnant women who have had the EFW calculated by ultrasonography up to seven days before delivery and the NW established immediately after birth, with a specific newborn's scale. The correlation between EFW and NW measurements was assessed by Pearson's correlation coefficient and by the mean difference between them. EFW and NW were classified as: low for the gestational age (LGA), adequate for the gestational age (AGA) and high for the gestational age (HGA), according to the percentiles 10 and 90 of the respective reference curves. The diagnosis of EFW deviation has been validated using the values of the Alexander's NW reference curve as gold-standard, by estimating the sensitivity, specificity, and positive and negative predictive values. RESULTS: there has been a high linear correlation between the EFW and NW (R=0.96), and the difference between them has varied from -474 g to +480 g, with an average of +3 g. Most of the highest percent weight estimate variations were between 10 and 15%. EFW has had 85.7% of sensitivity and 100% of specificity for the detection of LGA, and 100 and 77.2%, respectively, for the detection of HGA. CONCLUSIONS: EFW is able to predict NW adequately, and the reference EFW tested has had a good performance in the screening of fetal growth deviation, in the population studied.

Purpose:to compare the incidence of preterm labor and birth, premature rupture of membranes (PROM) and low birth-weight newborns (< 2,500 g) between two groups of pregnant women (with or without BV). To verify the adequacy of including a regular prenatal BV investigation. Methods:a total of 217 women between 28 and 32 weeks of pregnancy (35 with BV and 182 without BV) were studied. The diagnosis of BV was established according to Amsel's criteria. The data were analyzed by the chi² test, Fisher's test, Mann-Whitney test and the relative risk. Results:the incidence of preterm labor, preterm birth, PROM and low birth-weight was statistically higher in the group of women with BV than in the control group (29.4% vs. 3.8%; 28.6% vs. 3.3%; 22.9% vs. 10.4%; 20.0% vs. 3.3%; respectively). The means of gestational age and birth-weight were significantly lower in the newborns from mothers with BV (265.8 days vs. 279.9 days; 2,958 g vs. 3,294 g, respectively). Conclusion:all perinatal complications studied were significantly associated with the presence of untreated BV during pregnancy. Therefore, the diagnosis and adequate treatment should be included in the routine prenatal assistance at Brazilian Obstetrics Services. Such measure may be effective in the reduction of these perinatal complications.

To validate the translation and adaptation to Brazilian Portuguese of 36 items from the World Health Organizaton Disability Assessment Schedule 2.0 (WHODAS 2.0), regarding their content and structure (construct), in a female population after pregnancy.
This is a validation of an instrument for the evaluation of disability and functioning and an assessment of its psychometric properties, performed in a tertiary maternity and a referral center specialized in high-risk pregnancies in Brazil. A sample of 638 women in different postpartum periods who had either a normal or a complicated pregnancy was included. The structure was evaluated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while the content and relationships among the domains were assessed through Pearson's correlation coefficient. The sociodemographic characteristics were identified, and the mean scores with their standard deviations for the 36 questions of the WHODAS 2.0 were calculated. The internal consistency was evaluated byCronbach's α.
Cronbach's α was higher than 0.79 for both sets of questons of the questionnaire. The EFA and CFA for the main 32 questions exhibited a total variance of 54.7% (Kaiser-Meyer-Olkin [KMO] measure of sampling adequacy = 0.934; p < 0.001) and 53.47% (KMO = 0.934; p < 0.001) respectively. There was a significant correlation among the 6 domains (r = 0.571-0.876), and a moderate correlation among all domains (r = 0.476-0.694).
The version of the WHODAS 2.0 instrument adapted to Brazilian Portuguese showed good psychometric properties in this sample, and therefore could be applied to populations of women regarding their reproductive history.

To define transvaginal ultrasound reference ranges for uterine cervix measurements according to gestational age (GA) in low-risk pregnancies.
Cohort of low-risk pregnantwomen undergoing transvaginal ultrasound exams every 4 weeks, comprisingmeasurements of the cervical length and volume, the transverse and anteroposterior diameters of the cervix, and distance fromthe entrance of the uterine artery into the cervix until the internal os. The inter- and intraobserver variabilities were assessed with the linear correlation coefficient and the Student t-test. Within each period of GA, 2.5, 10, 50, 90 and 97.5 percentiles were estimated, and the variation by GA was assessed with analysis of variance for dependent samples. Mean values and Student t-test were used to compare the values stratified by control variables.
After confirming the high reproducibility of the method, 172 women followed in this cohort presented a reduction in cervical length, with an increase in volume and in the anteroposterior and transverse diameters during pregnancy. Smaller cervical lengths were associated with younger age, lower parity, and absence of previous cesarean section (C-section).
In the studied population, we observed cervical length shortening throughout pregnancy, suggesting a physiological reduction mainly in the vaginal portion of the cervix. In order to better predict pretermbirth, cervical insufficiency and premature rupture of membranes, reference curves and specific cut-off values need to be validated.

Purpose: to evaluate, in a prospective way, the performance of the fine needle aspiration biopsy in the differential diagnosis of palpable breast masses. Method: the sensitivity, specificity, positive and negative predictive values for this test were evaluated in 102 women with age above 30 years and a palpable breast mass, who were attended at the University of Campinas. All punctures were performed by the same examiner. Results: the procedure had a sensitivity of 97%, specificity of 87%, positive predictive value of 94% and negative predictive value of 93%. The insufficient or unsatisfactory sample rate was 16% for the first aspiration, decreasing to 2% with a new procedure. Conclusions: this test showed to be highly sensitive and specific for the differential diagnosis of palpable breast masses, reassuring its great importance for the clinical approach of palpable masses.
