Reductions in breast cancer risk observed in daughters of pre-eclamptic pregnancies are hypothesized to be mediated by lower in utero estrogen concentrations. Whereas maternal urinary estriol excretion is generally lower in pre-eclamptic women, results for maternal blood concentrations are equivocal, and little is known about estrogen concentrations in the cord ...

OBJECTIVE: To carry out a prospective study of Doppler velocimetry of the fetomaternal circulation in women with chronic hypertension, to evaluate whether the subsequent development of superimposed pre-eclampsia can be predicted. STUDY DESIGN: Serial Doppler studies of the maternal uterine and renal arteries, and fetal middle cerebral and umbilical arteries, ...

Decidual acute atherosis is associated with pre-eclampsia, but the underlying mechanism is still unclear. We have previously demonstrated elevated level of the oxidative stress marker 8-isoprostaglandin F(2 alpha)(8-isoprostane) and lipids in pre-eclamptic decidual tissue. Arachidonic acid (AA) in tissue phospholipids is a source for 8-isoprostane generation, and 8-isoprostane is liberated ...

We followed 70 adult patients with spinal tuberculosis for a minimum of 2 years. Forty patients were treated by ambulant multi-drug chemotherapy (group A), and 30 with neurological complications (group B) were treated by antero-lateral decompression and chemotherapy.

Transport of iron from the mother to the fetus is essential for the normal development of the fetus and abnormalities in the transferrin receptor (TFR) on the placental trophoblasts might have some crucial effects on the fetal iron metabolism. The present study was undertaken to determine whether there are any ...

Pre-eclampsia, one of the main complications in pregnancy, is characterised by shallow cytotrophoblast invasion of decidua as well as by vascular endothelial cell dysfunction, leading to a poor perfusion of placenta. A striking feature of pre-eclamptic pregnancies is that expression of HLA-G protein is reduced in term placentas compared with ...
Parretti E - - 2003
OBJECTIVE: To evaluate the performance, in the prediction of pre-eclampsia, of (1) an abnormal mean uterine artery resistance index (RI; cross-sectional index) at 24 weeks of gestation, (2) the individual longitudinal flow pattern of results observed at 16, 20 and 24 weeks of gestation and (3) a multiple logistic regression ...
Sargent I L - - 2003
We have proposed that the maternal syndrome of pre-eclampsia is caused by a systemic inflammatory response involving both leucocytes and endothelium. This inflammatory response is present also in normal pregnancy, but in a milder form. The inflammatory stimulus is most likely to come from the placenta. Syncytiotrophoblast apoptotic debris, which ...

Neurofibromatosis in pregnancy has been associated with poor perinatal outcome. A 30-year-old multigravida developed peripheral lesions of neurofibromatosis during the third month of pregnancy. She had eclampsia complicated with fatal left-sided massive intracerebral haemorrhage detected on computed tomography at 8.5 months gestation. Investigations were suggestive of HELLP syndrome. A still-born ...

Antiphospholipid antibody syndrome (APS) is associated with adverse pregnancy outcomes and maternal complications including thrombotic events and early pre-eclampsia. HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets) represents a unique form in the spectrum of pre-eclampsia. This report describes four patients with pregnancy-associated hepatic infarctions. All four had APS and ...
Deborde S - - 2003
Pre-eclampsia (PE) is a disorder affecting 5-10% of all pregnancies and is characterised by abnormal trophoblast invasion, maternal endothelial cell dysfunction and a systemic maternal response. A unifying factor responsible for eliciting these effects remains unknown. However, levels of the autocrine insulin mediators, inositolphosphoglycans (IPG), are elevated 3-fold in pre-eclamptic ...

Pre-eclampsia is a potentially life-threatening disease of women during pregnancy leading to hypertension and proteinuria. It affects 1 in 15 pregnancies but, despite intense research efforts, the cause of the disease remains mysterious. Because pre-eclampsia only occurs during pregnancy and its symptoms resolve after delivery, factors from the placenta are ...

Normal pregnancy is associated with decreased peripheral vascular resistance, although the mechanisms are poorly understood. Pre-eclampsia is characterised by increased vessel resistance and a decreased relaxant capacity, contributing to the associated hypertension, multi-organ damage and intra-uterine growth restriction. An endothelium-derived vasoactive substance-endothelium-derived hyperpolarising factor may be responsible for the physiological ...

Impaired trophoblast invasiveness and spiral arterial remodelling, which results in poor placental perfusion during early pregnancy, is believed to cause fetal injury and growth retardation, and also endothelial cell activation/dysfunction in a susceptible mother, leading to clinical manifestations of pre-eclampsia. This article briefly reviews the regulatory roles of certain locally ...

PROBLEM: Reduced placental (trophoblast) cytokine interleukin-10 (IL-10) occurs in human pre-eclampsia. Along with an increase in inflammatory cytokines this may play an important role in the development of hypertension in pregnancy. It is not clear whether the changes in placental IL-10 are due to a change in the placental cell ...

During pregnancy extravillous trophoblast invades maternal uterine tissues and remodels spiral arteries. Maternal anaemia and early onset pre-eclampsia are associated with perturbed trophoblast biology. We systematically compared numerical density, invasive depth and apoptosis rates of extravillous trophoblast in uterine tissues taken from hysterectomies following Caesarean section after normal pregnancies (n=4) ...

The central role of the placenta in the pathogenesis of pre-eclampsia is undisputed. The evidence that maternal syndrome of pre-eclampsia is caused by a maternal systemic inflammatory response (MSIR) is reviewed. The polymorphic nature of the inflammatory network explains the diversity of the varied signs of this condition. A key ...

PROBLEM: The unusual pattern of human leukocyte antigen (HLA) expression on human trophoblasts could play an important role in successful pregnancy outcome. To determine whether alterations in HLA expression are associated with pregnancy abnormalities we have investigated expression of these antigens on chorionic and extravillous cytotrophoblasts. METHODS: Frozen tissue sections ...

In the third trimester of normal pregnancy, the mother tolerates daily shedding of several grams of dying placental trophoblast into the maternal circulation. The balance between apoptotic and necrotic shedding is presently unknown. Since pre-eclampsia is characterized by an altered placental oxygenation and increased trophoblast shedding, we investigated the role ...

Severe hypercalcaemia during pregnancy is rare and most cases are secondary to hyperparathyroidism. This is the first report of a parathyroid hormone related protein (PTHrP) secreting neuroendocrine tumour of the pancreas manifesting with severe hypercalcaemia during pregnancy. Measurement of PTHrP was useful in both the diagnosis and follow up of ...

1. Pre-eclampsia is a human disease of pregnancy characterized by high blood pressure, proteinuria and end-organ damage, if severe. Pre-eclampsia is thought to be related to changes in early placental development, with the formation of a shallower than normal placental bed. 2. Transforming growth factor (TGF)-beta1 is a multifunctional fibrogenic ...
