introduction:  preeclampsia is the common and dangerous complication of pregnancy with unknown reason. multiple causes such as depression, psychological and physical stress may be involved in its development. this study was performed to determine the relationship between anxiety during pregnancy and the incidence of preeclampsia. methods: this case-control study was conducted on 150 pregnant wo...

this survey assessed predisposing factors of preeclampsia and eclampsia in persons referring to governmental hospitals of hormozgan province. samples of this study were pregnant women who had preeclampsia and eclampsia and also pregnant women who had not preeclampsia and eclampsia (control group) referring to governmental hospitals of hormozgan province from september 1994 to february 1995. all...

BACKGROUND Preeclampsia is a disease with great variability in incidence across the world. The mortality is higher in lower income countries, where it is the leading cause of maternal mortality. This study aimed to determine the frequency of and risk factors for preeclampsia in a low income population from an urban area of Brazil. METHODS A prospective case control study of 242 women of which...

OBJECTIVE Preeclampsia is one of the most common complications of pregnancy. It is a trophoblastic disorder. Since human chorionic gonadotropin (hCG) is secreted by trophoblast, the purpose of the study was to determine the levels of beta (hCG) in preeclampsia and normal cases. METHODS This study was conducted on 40 term pregnant women with preeclampsia (case group) and 40 normal pregnant cas...

introduction: regarding to the recent advances in assisted reproductive techniques (art), twin and multiple pregnancies have increased during past years. objective: this study was performed to compare obstetrics and perinatal outcomes of dichorionic twin pregnancy following art with spontaneous pregnancy. materials and methods: in this cross-sectional study which was performed in ghaem hospital...

Implantation, trophoblast development and placentation are crucial processes in the establishment and development of normal pregnancy. Abnormalities of these processes can lead to pregnancy complications known as the great obstetrical syndromes: preeclampsia, intrauterine growth restriction, fetal demise, premature prelabor rupture of membranes, preterm labor, and recurrent pregnancy loss. Ther...

Abnormal placenta trophoblast proliferation and apoptosis is related to the pathogenesis of preeclampsia. Emerging evidence has also indicated that key pregnancy-associated hormones, such as hCG, progesterone, are found in high concentration at the maternal-fetal interface. The purpose of this study was to investigate the expression of CYP11A, a key enzyme in steroid hormone synthesis and metab...

Aim: Alterations in thyroid function with a simultaneous increase of hCG in some pregnancy diseases have been reported. However, the relationship between thyroid hormones and hCG during preeclampsia is not yet evaluated. In this study we determined serum levels of hCG, TSH, free T3 (fT3) and free T4 (fT4) in normal pregnant woman and in patients with preeclampsia and evaluated the correlation b...

Background Development of predictive models of preeclampsia has only yielded modest results. We hypothesized that impaired indices of microcirculatory function could be detected using sidestream dark field imaging. The objective of this study was to examine microvascular function in women at high risk for preeclampsia at mid-gestation. Methods Women between 16 and 22 weeks of gestation were s...
