    PURPOSE: to evaluate the toxicity of tacrolimus on embryonic development in rats treated during the tubal transit period. METHODS: sixty Wistar rats were distributed into four groups (15 animals each), which received different doses of tacrolimus through intragastric administration: (T1) 1.0 mg/kg/day, (T2) 2.0 mg/kg/day and (T3) 4.0 mg/kg/day. The control group (C) received distilled water. The rats were observed daily to detect clinical signs of toxicity. The treatments were performed from the first to the fifth day of pregnancy. The following maternal variables were analyzed: body, ovary, liver, and kidney weights, food intake, number of corpora lutea, implants, alive and dead fetuses, and implantation rates. The fetuses and placentae were weighed and the former were observed in order to detect external malformation. Statistical analysis was performed by one way: analysis of variance (ANOVA), folowed by the Dunnet test (alpha=0.05). RESULTS: there were no signs of maternal toxicity, such as body weight loss, decrease in food intake or in organ weights (p>0.05). There was also no significant difference among weights of fetuses (C: 1.8±0.6; T1: 2.2±0.5; T2: 1.9±0.5 and T3: 2.0±0.5 g) and placentae (C: 1,6±0.4; T1: 1.5±0.4; T2: 1.8±0.4 e T3: 1.6±0.4 g), with p>0.05; no external malformation was detected in the fetuses. CONCLUSIONS: the administration of tacrolimus to pregnant rats during the tubal transit period does not seem to generate any toxic effect to mother or embryo.

    PURPOSE: to analyze the association of pregnancy in adolescence with low birth weight (LBW). METHODS: all the patients who gave birth in a teaching Hospital at Maranhão State from July to December 2006 were included in the study and were split in two groups: adolescents (ten to 19 years old) and adults (20 to 34 years old). The variables studied were: skin color, schooling, marital status, family income, number of pre-natal appointments, gestational age at the onset of pre-natal assistance, place where they spend that period, gestation duration, delivery route and birth weight. Data were processed by the Epi-Info program, 3.4.1 version, and the associations between variables were analyzed by the Odds Ratio (OR), with a confidence interval (CI) of 95%. Models of logistic regression were also used. The significance level adopted was 0.05. RESULTS: 1,978 patients were evaluated. A ratio of 25.4% of deliveries in adolescents was observed; they presented low level of schooling, no mates, low number of pre-natal appointments, late onset of pre-natal assistance, low birth weight and prematurity. In the analysis of LBW as end variable, associated to prematurity (OR=29.0), it was clear the association with low number of pre-natal appointments (OR=2.98; 95%CI=2.23-4.00), pre-natal late onset (OR=1.91; 95%CI=1.3-2.6) and low schooling (OR=1.95; 95%CI=1.4-2.5) related to adolescence (OR=1.50; 95%CI=1.1-1.9). Similar results were obtained when the prematurity variable was excluded. Adolescents showed lower incidence of caesarean section (33.3%) than adults (49.4%), a significant difference, besides lower association with pre-eclampsia and cephalo-pelvic disproportion. CONLUSIONS: pregnancy in adolescence was associated to pre-natal late onset and low number of appointments, besides low schooling, low birth weight and a lower incidence of cephalo pelvic disproportion and pre-eclampsia.

    PURPOSE: to determine caffeine consumption in pregnant women and to evaluate its association with demographic, socioeconomic, reproductive, lifestyle and maternal nutritional status. METHODS: it is a cross-sectional study performed between 2005 and 2007. The present analysis refers to the period among the 8th and 13th gestational week and included 255 pregnant women from 18 to 40 years, clients of a municipal health center in Rio de Janeiro. The outcome variable was caffeine consumption, quantified by a semi-quantitative food frequency questionnaire, which count with a list containing 81 items and eight options of consumption frequencies; besides it being previously validated in a sample of employees of the State University of Rio de Janeiro. The caffeine intake was quantified starting from the consumption of: powdered chocolate, chocolate bar or chocolate, soft drink, coffee and mate tea. The statistical analysis was performed by means of fitting a multivariate linear regression. RESULTS: the median and the mean caffeine consumption were, respectively, 97.5 and 121.1 mg (standard deviation, sd = 128.4). The high caffeine consumption (> 300 mg/day) was observed in 8.3% of pregnant women. It was observed in the multivariate model that women with earlier menarche (β = -0.15), with more household partners (b = 0.17) and who didn’t make use of medicines (β = -0.24) presented larger tendency to high caffeine consumption association that was statistically significant (p <0.05). CONCLUSIONS: the caffeine consumption for most of the pregnant women was inferior to the limit of 300 mg/day as commited in other studies. Tendency was observed toward higher consumption of caffeine in pregnant women with earlier menarche, with more household partners and who didn’t make use of medicines.

    PURPOSE: to evaluate the meiotic spindle and the chromosome distribution of in vitro matured oocytes obtained from stimulated cycles of infertile women with polycystic ovary syndrome (PCOS) and with male factor and/or tubal infertility (Control Group) and compare in vitro maturation (IVM) rates between the groups analyzed. METHODS: five infertile patients with PCOS and eight controls, submitted to stimulated cycles for intracytoplasmic sperm injection, were selected prospectively and consecutively, and respectively assigned to the study group and the Control Group. Immature oocytes (21 and 29, respectively, from PCOS and Control Group) were submitted to IVM. After IVM, oocytes with first polar body extruded were fixed and submitted to immunostaining and fluorescence microscopy for morphological evaluation of the spindle and of chromosome distribution. Statistical analysis was performed by the Fisher test with significance, when p<0.05. RESULTS: IVM rates were similar between groups (47.6 e 44.8%, respectively, for PCOS and Control Group). Six of the ten oocytes (60%) from the study group and four of the 12 oocytes (33.3%) from the Control Group presented meiotic anomalies of the spindle and/or anomalous chromosome distribution, without statistical difference between groups. CONCLUSIONS: data from the present study did not demonstrate significant difference neither in IVM rates nor in the proportions of meiotic anomalies between in vitro matured oocytes obtained from stimulated cycles from PCOS patients and control ones.

    PURPOSE: to describe the socio-demographic characteristics of deaths caused by uterine cervix cancer in women living in Recife, Pernambuco, Brazil, from 2000 to 2004. METHODS: a transversal populational study, including 323 deaths by uterine cervix cancer, among which 261 were recorded in the Information System about Mortality and 62 were identified after investigation on deaths by cancer at non-specified sites of the uterus. Mortality rate for all the variables was obtained and statistics for central tendency and variance were calculated. The χ2 test was performed to obtain the mortality coefficient concerning the living place and age range of the patients. RESULTS: death among women under 60 (54.7%), black (60.5%), single (67.6%), housewives (71.2%) and the ones living in poor neighborhood (53.3%) preponderated. Most of deaths occurred in hospitals (85.1%) and 90.2% of them occurred inside national health system hospitals. The mortality coefficient varied from 0.3 (among women under 30) to 54.9/100.00 (among women over 80). Significant statistical differences (p<0.05) were evidenced when death linked to age range and sanitary district was compared to characteristics of the female population living in the city. CONCLUSIONS: in Recife, death by cervix cancer are more frequent among adult, black, single, housewives, women living in poor neighborhoods and attended to at national health system hospitals, with differences in death risk among age ranges and living place.

    Camptomelic dysplasia belongs to a heterogeneous and rare group of lethal skeletal dysplasias, characterized by abnormal development of bones and cartilages. It is caused by a mutation in gene Sox9 (SRY-like HMG [high-mobility group] BOX 9) of chromosome 17 and it is transmitted as an autosomal dominant trait. Its main characteristics are the shortening and bowing of the long bones, principally the lower limbs. It is also associated with other severe skeletal and extraskeletal malformations. Karyotype study may reveal sex reversal. The majority of carriers die during the fetal and early neonatal periods. Ultrasound is essential to elucidate a prenatal diagnosis.
