OBJECTIVE: to establish the rate of toxoplasmosis soroprevalence in postpartum women, attended in two hospitals of the Public Health System (SUS) in Cuiabá, and its correlation with age, previous abortion and women's knowledge of the disease. METHODS: a cross-sectional study including 205 women with ages from 14 to 43 (mean 22.4) years old, attended in these hospitals for two months, in the first or second days postpartum. Each woman answered a short questionnaire and had peripheral blood sample collected. Blood samples were stored at 20°C until assay. The seroprevalence was determined by quantitative detection of specific IgG antibody against Toxoplasma gondii, using a microparticle enzyme immunoassay. All samples were assayed at the same time. RESULTS: The average number of pregnancies in the women included in this study was 2.2, and the majority of them was pregnant for the first time. The seroprevalence found was 70.7% (165 of 205 women). No statistical correlation was found between seroprevalence and age (p = 0.967) or previous abortion (p = 0.82). Most of the women in this study (78%) did not know about toxoplasmosis and no statistical correlation was found between this condition and seroprevalence (p = 0.49). CONCLUSION: the high seroprevalence found in the present study is in accordance with surveys previously reported in our country and other developing countries. Among the women included in this study, an expressive number (29.3%) is still under risk of contamination. The lack of statistical correlation between seroprevalence and women's age, lack of knowledge about the disease and report of previous abortion is in accordance with some previous studies and in disagreement with others.

PURPOSE: to check whether there were differences in some social indicators between adolescent and adult pregnant women in the city of Ribeirão Preto, from January 1992 to December 1996. METHODS: the information was obtained from hospital discharge forms and was analyzed at the Hospital Data Processing Center of the FMRP-USP. The analyzed parameters were: number and types of deliveries, category of hospital admission, occupation, and obstetric diagnosis. The 6.04a text processor Epi-Info System, a data bank and statistics of epidemiology produced by the Centers of Disease Control and Prevention (Atlanta, GA, USA), and Dbase IV were used to process the information. The association between variables was tested by the chi² test, with level of significance set at 5%, using the GraphPad Prism version 2.0, 1995 software. RESULTS: a total of 43,253 deliveries occurred during this period, among which 7,134 (16.5%) corresponded to adolescent deliveries, while 36,119 (83.5%) to adult deliveries. The number of deliveries by adolescent girls increased 25.5% along this period. The proportion of adolescent deliveries in the unified health system category of admission increased, and it was higher than that of the adults'. Only 14.1% of the adolescents belonged to the economically active population, comparing with 34.8% of the adults. Only 6.8% of the adolescents were students, while 79.0% were house-workers or had a nonpaid occupation. In the analyzed period, the ratio of vaginal delivery increased among the adolescents, as compared to that of the adults. The ratio of cesarean delivery persisted stable and higher among the adults. Premature delivery and false labor were significantly more frequent among the adolescents. CONCLUSION: the number of deliveries increased among the adolescents, and most of them were normal. The ratio of admission by the unified health system category and that of vaginal delivery were higher among the adolescents. There were more adolescents without an economically active work. Thus, we recommend strategies to prevent adolescent pregnancy, mainly among the poor population.

OBJECTIVE: to investigate whether it is possible to predict acidemia at birth in pregnancies with placental insufficiency using venous-arterial indices: pulsatility index for vein (PIV) of the ductus venosus (DV) over PI of the middle cerebral artery (MCA) and PIV of the DV over PI of the umbilical artery, and establish cut-off values for this prediction. PATIENTS AND METHODS: this was a prospective cross-sectional study involving forty-seven patients with placental insufficiency (umbilical artery resistance and pulsatility indices above the 95th percentile for gestational age) who were submitted to Dopplervelocimetry in the last 24 hours before delivery. All pregnancies were singleton, over 26 weeks of age and without structural or chromosome anomalies. Arterial cord blood was obtained for gasometry immediately after birth. Acidemia was defined as umbilical arterial pH < 7.20 in the absence of uterine contractions and pH < 7.15 in the presence of contractions. Metabolic or mixed acidemia at birth were considered pathological. A ROC curve was calculated for the venous-arterial indices: PIV DV/PI umbilical artery (UA) and PIV DV/PI MCA. A cut-off value was established and sensitivity, specificity, accuracy, positive and negative predictive values and positive and negative likelihood ratios were calculated. RESULTS: The DV/UA PI index was not a good predictor of acidemia at birth. The DV/MCA PI index was related to acidemia at birth (area under the curve 0,785, p = 0,004). The cut-off value was: 0,582, sensitivity 66,7%, specificity 77,1 and accuracy 74,5%. CONCLUSION: the PIV DV/PI MCA ratio is adequate for predicting acidemia at birth in pregnancies with placental insufficiency. The cut-off value was: 0,582.

PURPOSE: to assess the correlation between middle cerebral artery peak systolic velocity and umbilical cord blood hemoglobin concentration and to determine its diagnostic value. PATIENTS AND METHODS: a cross-sectional prospective study was performed from January 2000 to May 2003. Forty-four isoimmunized pregnant women underwent a protocol for the identification of fetal hemolysis. When intrauterine transfusions were indicated, the umbilical cord blood hemoglobin concentration was measured at the beginning of the procedure. Each intrauterine transfusion preceded by Doppler velocimetry of the middle cerebral artery was regarded as one case, summing up eighty-three procedures. In all cases, the middle cerebral artery Doppler examinations were performed within the three hours preceding fetal blood sample collection. The systolic velocity peak was recorded and considered abnormal when its value was above 1.5 times the median for the corresponding gestational age. Hemocue® (B-Hemoglobin Photometer Hemocue AB; Angelholm, Sweden) was the device used to measure fetal hemoglobin concentration. The relationship between middle cerebral artery peak systolic velocity and cord blood hemoglobin was obtained by the chi2 test, considered significant at p<0.05. RESULTS: in thirty-three cases the cord blood hemoglobin concentration was below 10.0 g/dL. There was a strong correlation between the two measured variables (p<0.001). The middle cerebral artery peak systolic velocity with values above 1.5 times the median was associated with cord blood hemoglobin concentration below 10 g/mL (p<0,001). The sensitivity of an increased middle cerebral artery peak systolic velocity was 75.8% for the detection of a cord blood hemoglobin level of 10 g/dL or lower. CONCLUSION: the middle cerebral artery peak systolic velocity can be used as a noninvasive method for the diagnosis of fetal anemia.

OBJECTIVE: to characterize the features of pregnant women who had elective preterm delivery, and correlate clinical and obstetrical diagnosis with neonatal results. METHOD: A total of 100 pregnant women admitted in the Obstetric Clinic ward and their respective newborns has been evaluated. The inclusion criteria were: single pregnancy, confirmed gestational age by an early scan, absence of labor symptoms and the presence of a maternal or fetal condition leading to preterm delivery indication. The direct causes of elective preterm delivery were classified in groups, to relate them to the neonatal results, taking into account the gestational age. To assess the neonatal results, the following criteria were analyzed: acidosis; 1st and 5st minute Apgar score lower than 7; intracranial hemorrhage; neonatal death; sepsis and respiratory distress syndrome. Statistical analysis used to correlate the causes of delivery and the gestational age to the neonatal results was done by log-linear models. RESULTS: One patient was excluded from the study due to fetal malformation. The most common direct causes of delivery were prenatal fetal distress (49.5%), hypertensive syndromes (21.2%), intra uterine growth restriction (13.1%) and others (16.2%). Among the main neonatal complications there were asphyxia (33.3%), acidosis (30.4%), respiratory distress syndrome (RDS) (26.3%), sepsis (22.2%), intracranial hemorrhage (21.2%) and neonatal death (13.1%). The cause of delivery was associated with acidosis and RDS by log-linear models and the gestational age was associated with RDS, 1st minute Apgar <7, sepsis, intracranial hemorrhage and neonatal death. CONCLUSIONS: the cause of delivery influences the neonatal results. Nevertheless, the most severe complications are directly dependent on the gestational age of delivery. Therefore, the prenatal diagnosis should be rigorously evaluated by the obstetrician, so that the decision to interrupt the pregnancy could be taken at the suitable moment, thus avoiding neonatal complications.

PURPOSE: to study the prevalence of colonization by group B Streptococcus in pregnant women in the last three months of gestation, and to evaluate the association of colonization with demographic and clinical maternal variables. METHODS: from October 8, 2002 to March 26, 2003, a transversal study of prevalence of colonization by group B Streptococcus was carried out in 309 pregnant women in the last three months of gestation. Samples of vaginal and anorectal secretions were collected and were tested for presumptive identification of group B Streptococcus. The pregnant women were studied according to race, age, level of instruction, family income, number of gestations, gestational age, history of urinary tract infection during present pregnancy, premature rupture of membranes and duration of ruptured membranes, intrapartum fever, chorioamnionitis, meconium in the amniotic fluid, spontaneous or cesarean section delivery, postpartum fever, and postpartum endometritis. RESULTS: fourty-six pregnant women were diagnosed with group B Streptococcus: 26 of them (56.5%) had positive vaginal culture, 8 (17.4%) positive anorectal culture and 12 (26.5%) had both vaginal and anorectal positive cultures. None of the maternal variables were statistically significant with respect to group B Streptococcus colonization. The results were submitted to chi2 bivariate analysis and, when appropriate, Fisher's exact test. CONCLUSION: the prevalence rate of vaginal and anorectal colonization by group B Streptococcus in pregnant women in the last three months of gestation, in Londrina - Paraná, was 14.9%.

PURPOSE: to analyze vaginal contents using the fresh wet mount of a cytological exam in the first prenatal visit of women with or without genital complaints and correlate the conclusion with the results from the Pap smears. Microscopy during pregnancy should be valued and recognized as a method capable of providing immediate diagnosis in 90% of bacterial vaginosis, candidiasis and trichomoniasis cases. METHODS: a prospective study was performed in 216 pregnant women selected from the prenatal department of a public hospital, between October 30, 2001 and November 12, 2002. Two samples were collected from the posterior vaginal vault and deposited onto two separate microscope slides. To one slide, a droplet of 0.9% NaCl was applied and to the other, a droplet of 10% KOH. Both slides were covered with a coverslip for immediate microscopic evaluation. Tests were perfomed in one drop of the material to examine pH and whiff. The microscopic examination of the material was carried out at a 100X, 400X and exceptionally 1000X magnification. Pap smears were performed in all pregnant patients. The correlation between the results of the utilized cytological methods was perfomed by the kappa coefficient, which evaluates the concordance for quality variables. RESULTS: the findings of the normal vaginal microflora in the fresh wet mount were 7.8%, representing the most observed cytological aspect, and without correspondence with the 3.70% verified by the Pap smears. In the fresh wet mount, bacterial vaginosis was found in 30.9% and candidiasis in 7.9% of the cases. However, in the Pap smears no similar event occurred, the diagnosis being 0.7 and 24.3%, respectively. The absence of a diagnosis correlation of nonspecific bacterial vaginitis by direct microscopy (17.5%) and Pap smears (51.3%) is probably due to the undervalued diagnosis of bacterial vaginosis by the latter method. The diagnosis of trichomonas vaginalis observed in both cytological methods (3.70 and 2.78%) represents a low prevalence of these parasites in the course of pregnancy. The kappa coefficient between the two cytological procedures in the several microbiological findings showed low correlation of the diagnosis of bacterial vaginosis with nonspecific vaginitis, as well as the normal vaginal flora. CONCLUSIONS: although the Pap smear presents the best accuracy of the diagnosis of yeast without pseudomycelium, the fresh wet mount has shown to be a better appraiser of nonepithelial cells the vaginal smears. Because Pap smears allow a better evaluation of vaginal epithelial cells, they represent the most important tool to show the aggressions and reactions of the nucleus and cytoplasm.

PURPOSE: to evaluate the experience of implementation of the Brazilian Prenatal and Birth Humanization Program (PHPN) in 2001 and 2002, through a population descriptive study. METHODS: the study was performed through documental analysis and using data generated by SISPRENATAL, comparatively evaluating the indicators concerning criteria for prenatal follow-up in different states, regions and period. RESULTS: until the end of 2002, 3983 municipalities joined the Program (72% adhesion) and, among them, 71% reported results, constituting a data base of 720,871 women. In 2002 only 28% of the pregnant women were already registered, 25% before 120 days of pregnancy. Nearly 22% of the women had six prenatal visits, 6% had the post-partum visit and the compulsory tests performed, only 4% had also the HIV test and were vaccinated against tetanus, and 12% had two examinations performed for syphilis. There were important regional variations, generally showing better indicators for the Southeast and South regions. CONCLUSIONS: although the indicators of quality of care showed an improvement from 2001 to 2002, the recorded low percentages attest the need for permanent evaluations and new interventions with the aim of improving the quality of this care, especially in the North and Northeast regions.
