PURPOSE: to analyze the differential diagnosis, follow-up and therapeutic approach in five cases of primary cardiac tumors diagnosed during the prenatal period. METHODS: during the period from January 1997 to December 2008, 7989 pregnant women were submitted to morphological ultrasound due to the presence of risk factors for fetal malformations. Fetuses with hyperechogenic intracardiac masses larger than 1 mm diagnosed by ultrasound evaluation of the fetal heart, were selected for study. The differential diagnosis between the different tumor types was made on the basis of the ultrasound characteristics of the masses. RESULTS: five fetuses with hiperechogenic intracardiac masses were diagnosed, corresponding to a 0.06% prevalence rate. Gestational age ranged from 28 to 36 weeks (mean: 31), and maternal age ranged from 23 to 45 years (mean: 34,2). The most frequent location of the masses was the left ventricle (100%). Echographically, all masses were single or multiple, hyperechogenic, homogeneous and well delimited, compatible with a diagnosis of rhabomyoma. In cases in which the diameters of the masses were less than 20 mm, an expectant conduct was followed and no complications occurred during the prenatal period. One case with a huge tumor presented arrhythmia and cardiac insufficiency during the 35 gestational weeks, and the interruption of pregnancy was indicated. Tuberous sclerosis was associated in four cases (80%) and the diagnosis was confirmed during the postnatal follow-up. CONCLUSIONS: fetal morphological ultrasonography is the main form of early detection of primary cardiac tumors. The fetal cardiac evaluation is of fundamental importance for the differential morphological characterization of cardiac masses and for the evaluation of cardiac function. Rhabdomyomas are the most common type of fetal tumor. An expectant pre and postnatal conduct is followed, with a low risk of complications and with the possibility of spontaneous regression in most cases. Postnatal clinical follow-up is mandatory due to the high frequency of associated tuberous sclerosis.

PURPOSE: to evaluate the effectiveness of the IUGR model by uterine artery ligation mimicking placental insufficiency in rats. METHODS: sprague-Dawley rat fetuses were divided into three groups: IUGR (intrauterine growth restriction), with fetuses in the right horn of pregnant rats subjected to right uterine artery ligation at 18.5 days of gestation (term = 22 days); C-IUGR (control of restriction), with control fetuses in the left horn, and EC (external control), with fetuses of intact rats. Animals were harvested by cesarean section at day 21.5 days of gestation. Fetuses were weighed and then sacrificed. The intestine, liver, kidney and placenta were weighed and dissected for morphometric and histological analysis. RESULTS: the morphometric data showed decreased body weight (BW), liver weight (LW) and intestinal weight (IW) of fetuses with IUGR compared to C-IUGR and EC (p<0.001). The placental weight (PW), renal weight (RW) and LW/BW, IW/BW, and RW/BW ratios did not change. IUGR fetuses had decreased kidney thickness (p<0.001) and decreased thickness of the intestinal mucosa and submucosa (p<0.05). Histological evaluation showed reduction of liver glycogen storage in fetuses with IUGR compared to C-IUGR and CE. CONCLUSIONS: the model described was efficient and caused symmetric fetal IUGR with decreased size of most organs, especially the liver, and changes in glycogen stores.

PURPOSE: to determine the factors associated with cesarean section in pregnancies with fetal death at a maternity hospital in Recife, Pernambuco, Brazil. METHODS: a cross-sectional study was performed, which analyzed data from the information system about mortality and medical records, from January 2005 to December 2008, of Hospital Barão de Lucena (HBL). We analyzed women with fetal death diagnosis, with gestational age of 20 weeks or more, in terms of sociodemographic characteristics, causes and types of fetal death, obstetrical precedents and birth characteristics. The associations between the variables were analyzed by the χ2 test of association and Fisher exact test, with the level of significance set at 5%. We calculated the prevalence ratio as the measure of risk and the confidence interval (CI) at 95%. Logistic regression analysis was also performed and the Odds Ratio (OR) was calculated. RESULTS: among the 258 pregnant women with fetal death, 27.5% (n=71) underwent cesarean section. After multivariate analysis, the factors that remained significantly associated with cesarean section were maternal age below 20 years (OR=0.23; 95%CI=0.06-0.85), history of one or more cesarean sections (OR=7.02; 95%CI=2.29-21.55), multiple gestation (OR=9.06; 95%CI=2.01-40.71), use of misoprostol for birth induction (OR=0.07; 95%CI=0.01-0.32), fetal death occurring during birth (OR=4.01; 95%CI=1.13-14.24), low birth weight (OR=0.33; 95%CI=0.11-0.94), presence of hypertensive disorders (OR=3.7; 95%CI=1.46-9.39) and abruptio placentae (OR=13.9; 95%CI=4.67-41.69). CONCLUSION: in HBL, the risk factors for cesarean section in pregnancies with fetal death were previous cesarean section, multiple gestation, intrapartum deaths, hypertensive disorders and abruptio placentae. The protective factors were teenage pregnancy, use of misoprostol and low birth weight.

PURPOSE: to estimate the prevalence infection of human immunodeficiency virus (HIV), human T-cell lymphotropic vírus (HTLV), hepatitis B virus (HBV), Chlamydia trachomatis (C. trachomatis) and syphilis in pregnant women, as well as risk factors associated with these infections, in Fundação de Medicina Tropical do Amazonas (FMTAM). METHODS: a cross-sectional study was carried including 674 pregnant women consecutively attended of the spontaneous demand of FMTAM between March and September 2008. Demographic, epidemiologic, socioeconomic, clinical and obstetric information have been collected through specific questionnaires. Patients had blood sample collected by peripheral venous for accomplishment of serological tests of HIV, HTLV, HBV and syphilis. Cervical secretion sample has been collected for C. trachomatis antigens detection test. The Odds Ratio has been used to evaluate risk factors associated to infections. Statistical analysis has been done with the t-Student, χ2 and Fisher's exact tests. RESULTS: the average age was 23.9 years old (SD 6.3). The observed prevalence was 0.6% to infection by HIV; 0.7% by HBsAg; 1.0% of syphilis and 2.7% by C. trachomatis. All the samples went negatives to HTLV. There were no variables associated with infection by HIV, HBV and syphilis. Significative statistically association was observed between pregnant woman with age under 20 years and of first pregnancy with C. trachomatis infection. CONCLUSIONS: the study evidenced that the prevalence infection by HIV in pregnant women assisted in FMTAM is similar to the values described in the Brazilian literature, while the prevalence by HTLV, HBV, syphilis and C. trachomatis in the studied population are below found by other authors. The main risk factor for the infection by C. trachomatis was being under 20 years old.

PURPOSE: to analyze the clinical and epidemiological profile, the outcome of pregnancy and the vertical transmission of human immunodeficiency virus (HIV)-infected pregnant women receiving prenatal care at the University Hospital of Santa Maria (HUSM). METHODS: A prospective study was conducted on 139 HIV-infected pregnant women attended at the High-Risk Prenatal Care Outpatient Clinic of HUSM, during the period from August 2002 to August 2007, with at least two prenatal visits in this service. Data were collected by an interview and by filling out a research protocol during a prenatal visit. The protocol was attached to the medical records of the patient and kept until the outcome of gestation. Descriptive analysis of quantitative variables was performed using the SPSS software, version 15.0. RESULTS: The mean age of the 139 pregnant women studied was 25.6 years (±5.8), 79 (56.8%) were white, 81 (58.5%) were married or lived in a stable union, and 90 (65.0%) had less than eight years of schooling. Fifty-one percent of the pregnant women already had two or more children, with a number of children higher than the mean for the state. The infection was diagnosed during the present or a previous pregnancy in more than 70.0% cases. Sexual exposure occurred in 97.0%, and in 59.6% of cases the partner was known to be infected. During the study period, among the cases properly monitored, only one newborn (0.7%) was infected with HIV. CONCLUSIONS: Young women in a socioeconomic situation of vulnerability, with low schooling and multiparous represent the majority of HIV-positive pregnant women attended at the service. Evaluations performed during the prenatal period were relevant for the diagnosis of infection in most cases. An early diagnosis associated with proper clinical, obstetrical and psychological monitoring and with nursing care is important to provide appropriate treatment compliance and a reduction of the rates of vertical transmission.

PURPOSE: to assess compliance with the recommendations for opportunistic breast cancer screening by mammography. METHODS: 460 women from the town of Taubaté, São Paulo, Brazil, were followed-up prospectively after the index mammography, 327 of them attended by the public health system and 133 by the private system. We evaluated the prevalence of mammography repetition, the adherence rates and predictive factors associated with the current recommendations of mammographic screening. The association of the outcomes with the independent variables was studied by obtaining the risk rates (RR) and the respective 95% confidence intervals (95%CI). The adjusted prevalence rates were calculated by the COX regression model. RESULTS: although more than 90% of the studied women repeated the mammography at least once, the rate of correct compliance with the recommendations of mammographic screening, with repetition of the procedure every 24 months, was low (about 30% of the study sample). The preditive factors associated with compliance with mammographic screening were related to the unequal access to public or private healthcare services (RR=1.77; 95%CI=1.26-2.48) and to previous screening (RR=3.07; 95%CI=1.86-5.08). CONCLUSION: we concluded that compliance with the recommendations of opportunistic mammographic screening for breast cancer was low in both studied population segments.

Uterine leiomyomas are characterized as a benign disease and are observed in 2 to 3% of all normal pregnancies. Out of these, about 10% may present complications during pregnancy. We present a case of a pregnant patient sought emergency obstetric care at the 17th week, complaining of severe pain, presenting with painful abdominal palpation and sudden positive decompression. Ultrasonography revealed a myoma nodule measuring 9.1 x 7.7 cm; the patient was hospitalized and medicated, being also submitted to laparotomy and myomectomy due to worsening of her condition. Prenatal care revealed no further abnormalities, with resolution of gestation at 39 weeks. The newborn weighed 3,315 g, with Apgar scores of 9 and 10. In such cases, clinical treatment should always be attempted and surgery should be considered only in selected cases, mainly in the impossibility of conservative treatment or when the patient's clinical features require immediate intervention. In this case, myomectomy was effective against maternal-fetal obstetric complications.
