Unexplained and recurrent loss of pregnancies is a heartbreaking and frustrating condition. The routine diagnostic workup for pregnancy loss includes hormonal evaluation, screening for genetic or chromosomal defects, immunologic and thrombophilic testing, and evaluation of congenital or acquired Müllerian defects. In cases of idiopathic pregnancy loss, defects in endometrial receptivity ...

Although many fetal birth defects, particularly those of the body wall and gut, are associated with abnormalities of the umbilical cord, the developmental relationship between these structures is largely obscure. Recently, genetic analysis of mid-gestation mouse embryos revealed that defects in Hedgehog signaling led to omphalocoele, or failure of the ...

Placental overproduction of anti-angiogenic soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sEng) has a key role in the development of preeclampsia (PE). Circulating endothelin-1 (ET-1) levels are also elevated in PE. In this study, we investigated the correlation between ET-1 and sFlt-1, placental growth factor (PlGF), sEng levels during ...

The objective of this study was to determine if the maternal serum concentration of insulin-like growth factor-binding protein-3 (IGFBP-3) at 11-13 week's gestation is altered in pregnancies that subsequently develop preeclampsia (PE). Maternal serum concentration of IGFBP-3, pregnancy-associated plasma protein-A (PAPP-A) and uterine artery pulsatility index (PI) were measured in ...

When pulmonary hypertension (PH) occurs in pregnancy, physiologic stress can overwhelm an already strained right ventricle resulting in right ventricular failure and death. Mortality remains unacceptably high (25%-30%). Patients with PH should be counseled to avoid pregnancy. This article discusses the physiologic changes of pregnancy that make it difficult for ...

There is no doubt that micronutrient deficiency is common in our environment. Replacements have thus been instituted without adequate information on specific and peculiar micronutrient needs of our people. Zinc is an essential micronutrient which is prone to maternal depletion during pregnancy and lactation. Unfortunately, studies in that regard in ...

Since use of non-steroidal anti-inflammatory drugs (NSAIDs) during pregnancy is common, small increases in the risk of birth defects may have significant implications for public health. Results of human studies on the teratogenic risks of NSAIDs are inconsistent. Therefore, we evaluated the risk of selected birth defects after prenatal exposure ...
