Foi analisada a situação vacinal de 173 crianças de 0 a 2 anos de idade atendidas na Policlínica Hamilton Raulino Gondin situada num bairro periférico da cidade de Porto Velho, Rondônia. Os dados foram colhidos de maio a setembro de 2001 e obtidos através de entrevistas realizadas com o acompanhante da criança mediante a aplicação de formulário padronizado. Através deste instrumento foram analisadas as carteiras de vacina das crianças, tendo como critério o aprazamento das doses e colhidas informações referentes aos aspectos sócio-econômicos e culturais da família onde a criança está inserida. Os resultados mostraram que os maiores percentuais de atrasos encontrados foram 6,4% para a vacina contra a febre amarela e 5,8% para as vacinas contra sarampo (1ª e 2ª dose) e contra o Haemophilus influenza tipo b-Hib 3ª dose. Dentre os motivos de atrasos vacinais pesquisados o de maior relevância foi à falta de informação da mãe ou responsáveis. Estudando os fatores sócio-econômicos e culturais da família das crianças da amostra, evidenciou-se predominância de mães jovens, com idade entre 19 e 25 anos. Em relação ao grau de escolaridade do acompanhante das crianças, detectamos o percentual de 63,0% para o I grau incompleto. Analisando a renda das famílias das crianças do estudo observou-se que 29,5% vivem com rendimento compreendidos entre 1 e 2 salários mínimos.

A Síndrome de Down, ou trissomia do 21 é o distúrbio cromossômico mais freqüente em recém-nascidos. Esta trissomia é na maioria das vezes (95% dos casos) decorrente da não disjunção meiótica materna durante a meiose I. Com exceção da idade materna avançada, outros fatores de risco para não disjunção meiótica não estão bem estabelecidos. Estudos preliminares recentes sugerem que o metabolismo anormal do folato e polimorfismos no gene MTHFR (C677T e A1298C) podem ser fatores de riscos materno para Síndrome de Down. Com objetivo de verificar a freqüência dos polimorfismos no gene MTHFR (C677T e A1298C) e uma possível associação destes, como fatores de risco materno para Síndrome de Down, realizamos um estudo do tipo caso-controle, em 41 mulheres de filhos com a Síndrome de Down (freqüentadoras da APAE) e 39 controles da cidade de Belém-PA. Nossos resultados demonstraram que a distribuição dos genótipos para os dois polimorfismos entre as mães investigadas e controles se encontravam em equilíbrio de Hardy Weinberg. Não encontramos diferenças entre as freqüências nas mães investigadas e mães controles. Esses resultados sugerem que estas mutações isoladas e/ou em forma de haplótipos, não podem ser consideradas como risco materno para Síndrome de Down, para população analisada e sim polimorfismos comuns dentro desta população.

Objectives-The purpose of this study was to evaluate the association between placental volumes, placental vascularity, and hypertensive disorders in pregnancy.Methods A prospective case-control study was conducted between April 2011 and July 2012. Placental volumes and vascularity were evaluated by 3-dimensional sonographic, 3-dimensional power Doppler histographic, and 2-dimensional color Doppler studies. Pregnant women were classified as normotensive or hypertensive and stratified by the nature of their hypertensive disorders. The following variables were evaluated: observed-to-expected placental volume ratio, placental volume-to-estimated fetal weight ratio, placental vascular indices, and pulsatility indices of the right and left uterine and umbilical arteries.Results Sixty-six healthy pregnant women and 62 pregnant women with hypertensive disorders were evaluated (matched by maternal age, gestational age at sonography, and parity). Placental volumes were not reduced in pregnancy in women with hypertensive disorders (P > .05). Conversely, reduced placental vascularization indices (vascularization index and vascularization-flow index) were observed in pregnancies complicated by hypertensive disorders (P < .01; P < .01), especially in patients with superimposed preeclampsia (P = .04; P = .02). A weak correlation was observed between placental volumes, placental vascular indices, and Doppler studies of the uterine and umbilical arteries.Conclusions Pregnancies complicated by hypertensive disorders are associated with reduced placental vascularity but not with reduced placental volumes. These findings are independent of changes in uterine artery Doppler studies. Future studies of the prediction of preeclampsia may focus on placental vascularity in combination with results of Doppler studies of the uterine arteries.

The concern with infant mortality has been a priority in public policies, especially for Brazil to achieve the Millennium Development Goal number four: reducing child mortality by 75% by the year 2015. It is known that prematurity has an intimate relationship with mortality of children under one year and therefore it is necessary an effective intervention in risk factors linked to premature births. To evaluate the profile of mothers and newborn babies living in Botucatu-SP, in the period 2001 to 2009, focusing on prematurity. A quantitative study, retrospective, descriptive, epidemiological, from the Information System Newborn Alive. The prevalence of preterm births was 15.1%, and low birth weight 14.7%. Among infants, the Apgar score below 7 at 1 and at 5 minutes was 13.1% and 2.4% respectively. Considering the total of pregnant women studied, 20.3% were adolescents and 10.3% were aged 35 years or more and most (63.2%) had eight or more years of school approval. The profile of mothers of premature infants shows that 23.6% were teenagers, 14.1% had at least 35 years and 60.4% had at least primary education. With regard to premature deliveries, caesarean sections and 58.4% were between the total newborns, this type of delivery was achieved in 46.6% of cases. Prematurity was associated with an Apgar score below seven in the first and fifth minutes of life, presence of malformation and multiple pregnancy. Among maternal variables, prematurity was associated with extremes of maternal age, maternal education, history of stillbirth, primiparas, white and presence of the mother's partner. With regard to delivery was associated with cesarean section and outside the hospital. This study assessed maternal characteristics associated with prematurity and point out how relevant the pregnancies at the extremes of age and those that occur in women with low education level, indicating the interference...

During the pregnancy process, the maternal organism commonly undergoes changes. Such changes follow the normal course of pregnancy; however, some maternal or fetal factors can interfere with pregnancy and adversely affect its outcomes, thus triggering what is referred to as high-risk pregnancy, which is responsible for increasing maternal, fetal or newborns’ morbimortality rates1,2. One of the obstetric alternatives for a safe resolution of this pregnancy type is the caesarean section. Nevertheless, an expressive increase in the number of caesarean sections has been observed worldwide, and they are, many times, unnecessarily indicated8. The world Health Organization (WHO) recommends that the total number of caesarean sections in relation to the total number of deliveries performed at health service should be a maximum of 15% 11, a limit that is easily surpassed in various services. To outline the epidemiological profile of pregnant women submitted to caesarean sections at a reference health care service in the city of Botucatu-SP. This is a cross-sectional, retrospective, exploratory, descriptive, quantitative study. The target population consisted of one hundred pregnant women assisted in this institution, who had been submitted to caesarean sections in 2010 and were randomly selected to compose the sample. In the analyzed period, there were 1,189 deliveries, of which 601 (50.5%) were natural deliveries, 588 (49.4%) were caesarean sections. As regards maternal age, 76% were in the age range of 19 to 36 years. A high percentage of patients (27%) had not completed elementary education and did not have a paid job; 67% were homemakers. Most of the participants were married (56%); 34% of the women were primiparas, but 19% were in their fourth or more pregnancies. Concerning prenatal care, little was found, since many of them had consultations out of the institution which were not recorded... (Complete abstract click electronic access below)
