- Crescimento e actividade fetal às 20-24 semanas de gestação (estudo preliminar)Publication . Conde, A.; Figueiredo, B.; Tendais, I.; Pereira, A.; Nogueira, R.BACKGROUND: Recent researches show that psychological development begins much before birth and prenatal influences can explain a significant part of the future variability in infants' behaviour and development. AIMS: The aim of this study was to characterize the fetal development between 20 and 24 weeks of gestation, related to the measures of fetal growth-- iparietal diameter, abdominal circumference, head circumference, femur length and fetal weight-- and fetal activity--fetal heart rate and fetal movements. We also tried to establish if there are any differences in these measures related to the mothers' and fetus' sociodemographic features, obstetrical conditions and exposure to drugs. METHOD: The sample of this study involved 48 fetus (52.1% female and 47.9% male) with an estimated gestational age (GA) between 20-24 weeks (Mean = 21 weeks and 1 day), whose mothers had appointments at the Obstetric and Gynaecological medical consultation of Júlio Dinis Maternity Hospital (MJD, Oporto). A video tape of the fetal behaviour was made and ultrasound biometry measurements were collected from the morphological ultrasound report. RESULTS: A statistical analysis of fetal data, after gestational age control, showed differences in fetal growth measures related to mothers' occupational status [F(1,41) = 7.28; p = .000], marital status [F(1,41) = 2.61; p = .04], household arrangements [F(1,41) = 2.91; p = .03] and coffee consumption [F(1,40) = 2.55; p = .05]. Differences in fetal activity measures (fetal heart rate) associated to fetus gender [F(1,16) = 5.84; p = .009] were also found. CONCLUSIONS: We can conclude about the sensibility of fetal development to prenatal factors related to the mothers' and fetus' sociodemographic features and exposure to drugs.
- Quisto Porencefálico após Hemorragia Intracraniana: Evolução Imagiológica pré e pós-natalPublication . Cunha, A.; Mendes, M.; Ramos, C.; Nogueira, R.; Martins, M.; Veloso, P.; Mendes, R.RESUMO A infecção por Citomegalovírus (CMV) é a infecçâo congénita mais frequente. As manifestações clínicas são variáveis e multisistémicas. Do envolvimento do sistema nervoso central (SNC) podem resultar microcefalia, calcificações e, mais raramente, hidranencefalia e porencefalia por destruição do tecido cerebral. Estes achados são geralmente de diagnóstico tardio em Diagnóstico Pré Natal (DPN) com manifestações ecográficas muitas vezes inespecíficas. Os autores descrevem os aspectos imagiológicos ultrasonográficos no período fetal, neonatal, e tomográfico pósnatal num caso de hemorragia parenquimatosa cerebral com evolução para quisto porencefálico por provável infecção por citomegalovirus. Este caso mostra que achados ecográficos inespecíficos pré-natais numa paciente de alto risco têm um valor preditivo alto para infecção fetal por citomegalovirus e também podem ter significado prognóstico. ABSTRACT CMV is the most common congenital infection. Clinical manifestations can be multiple and affect different organs. Microcephaly, intracranial calcifications and less frequently hydranencephaly and porencephaly can be a consequence of cerebral involvement. These anomalies are generally diagnosed late in pregnancy after prenatal sonographic signs of little sensitivity. In this report, we describe the prenatal and neonatal images of cerebral hemorrhage and porencephaly, presumed secondary to intrauterine cytomegalovirus infection.This case shows that subtle ultrasound findings in a high risk pregnant woman may be predictive of sequelae in infected fetuses.
