Resumen El Ministerio de Salud brasileño recomienda que no se debe emitir el certificado defunción en los casos muerte fetal menos 20 semanas gestación, feto con peso inferior a 500 g o estatura 25 cm, pero agrega puede permitirlo cuando la familia opta por entierro del feto. En este contexto, emite pocos aborto. Este artículo realizó una revisión integradora partir pregunta: ¿Ayudarían proceso...

A new method of mid-trimester termination of pregnancy is described in which intra-amniotic urea was used. The mean interval between intra-amniotic injection and abortion was 59 hours and the mean length of hospital stay six days; the feto-maternal haemorrhage incidence was one out of 10 cases, which compares favourably with other methods. No complications have yet been encountered.

The placenta contains several types of feto-maternal interfaces where zygote-derived cells interact with maternal cells or maternal blood for the promotion of fetal growth and viability. The genetic factors regulating the interactions between different cell types within feto-maternal interfaces and the relative contributions of the maternal and zygotic genomes are poorly understood. Genomic imp...

Intrauterine growth retardation (IUGR) accounts for increased perinatal morbidity and mortality, and the early identification of the growth-retarded fetus remains a key factor in achieving the most favorable outcome for the infant and the mother. IUGR implies the operation of certain factors (such as hypertension, toxemia, and infection) which inhibit the achievement of the full genetic potenti...

The role of GH in the regulation of fetal growth and metabolism in late gestation is not well defined. The aim of this study was to determine the effects of exogenous GH infusion on fetal growth and feto-placental metabolism in the normally growing late-gestation fetal sheep. Eleven fetuses received pulsatile GH infusion (3.5 mg/day) for 10 days while 12 control fetuses received vehicle. The GH...

Our understanding why a woman's immune system does not reject her histoincompatible fetus is still very limited. Distinct insights into the mechanisms involved in pregnancy maintenance may help us to prevent pregnancy complications, e.g., miscarriages or pre-eclampsia. Immune integration and tolerance at the feto-maternal interface appear to be indispensable for successful pregnancy maintenance...

Os tumores cardíacos constituem condição rara, com incidência entre 0,17 e 28/10.000 na população geral. Os rabdomiomas são os tumores mais frequentes no período pré-natal. Este trabalho tem como objetivo relatar o caso de um feto com 31 semanas de gestação que apresentava tumoração intracardíaca de grandes dimensões, com graves repercussões clínicas. Unitermos: Diagnóstico pré-natal; Ultrasson...
