Fetal movements in utero are an expression of fetal well-being. However, a sudden increase of fetal movements is a sign of acute fetal distress, such as in cases of cord complications or abruptio placentae. Decreased fetal movements are seen in cases of chronic fetal distress such as preeclampsia, hypertension in pregnancy, etc. It was shown that in these(More)
Early in pregnancy, trophoblast invasion into the decidua and inner myometrium is essential for establishment of proper implantation, maternal-fetal exchange, and immunological tolerance of the feto-placental allograft. Unlike villous trophoblasts (VTs), extravillous trophoblasts (EVTs) are unique in their capacity to invade the maternal decidua and(More)
Fetal heart rate (FHR) accelerations associated with fetal movements is considered a sign of fetal well-being. Fetal movements as felt by the pregnant woman and visualized by real-time ultrasonography were correlated to FHR accelerations in 52 normal and high-risk pregnant women. All fetal movements felt by the mother or seen in the real-time(More)
Thrombotic thrombocytopenic purpura is a severe multisystemic disorder of unknown origin. The association of relapsing TTP with pregnancy is rare but well documented and high mortality rates of mothers and fetuses have been reported so far. Since the introduction of plasma therapy for treating the acute exacerbations of the disease, overall mortality rates(More)
A new device for recording fetal movements is presented. This device is composed of 2 sensors, incorporating a highly sensitive piezoelectric material. It is sensitive to rapid straining forces such as fetal movements and relatively insensitive to steady, slow movements such as uterine contractions and maternal respiratory movements. In this study of 20(More)
In high risk pregnancies with severe fetal distress, a reduction of fetal movements may take place before fetal death occurs. This decrease is accompanied by a weakening of the fetal movements. One hundred and twenty pregnant women (310 recordings) between 20 and 41 weeks gestation recorded fetal movements and classified them into weak, strong, and rolling.(More)
