Parturient females ingest placenta in most mammalian species, whereas fathers may do so in species in which both parents provide care for their offspring. To determine if the propensity to eat placenta varies with reproductive status in the biparental California mouse, we presented placenta to virgin (housed with a same-sex pairmate), expectant (pregnant with their first litter), and multiparou...

Purpose: Placenta previa and morbidly adherent placenta are life-threatening conditions that necessitate close monitoring during pregnancy can result in increased ante- intrapartum complications. This study aims to evaluate the frequency of placental disorders our population, reveal impact known risk factors on maternal morbidity, new predisposing their effects outcomes. Materials Methods: We p...

BACKGROUND Placenta percreta is the morbidly adherent form of all the placental invasion abnormalities. The pathology that underlies placenta percreta is poorly understood. AIMS To compare the levels of circulating vascular endothelial growth factor, placental growth factor and soluble fms-like tyrosine kinase 1 in pregnant women with placenta percreta to a control group. STUDY DESIGN Case-...

BACKGROUND Pregnant women with breast cancer present with a more advanced disease compared with non-pregnant women. Nevertheless, breast cancer metastasis to the placenta is rare. Trophoblast/tumor implantations share the same biochemical mediators, while only the first is stringently controlled. We hypothesized that the same mechanisms that affect/restrain placental implantation may inhibit me...

AIM To examine the factors associated with placenta praevia in primigravidas and also compare the pregnancy outcomes between primigravidas and nonprimigravidas. METHOD A retrospective cohort study was conducted in women who underwent caesarean section for major placenta praevia in a tertiary university hospital from January 2007 till December 2013. Medical records were reviewed. RESULT Amon...

Introduction Placenta diffusa though natural in sow and mare is a rare poss1bility in human beings, if the usual differentiation of the chorion into chorion frondosum and chorion leave does no t take place (Brews, 1957). Novak and Woodruff (1967) use the term placenta membranacea almost synonymously. The occurrence of this anomaly is attributed to defective decidua allowing deep implantation of...

Throughout in utero development, the placenta plays a key role in controlling growth and development. The placenta acts not only as a gatekeeper of nutrient and waste exchange between mother and developing fetus, but also as a regulator of the intrauterine environment. Its functions can be influenced by the environment encountered throughout pregnancy, thereby altering the appropriate genetic p...

INTRODUCTION Placenta percreta is associated with maternal morbidity and mortality. A hysterectomy is often needed to control the bleeding in such cases. However, it has been advocated that placenta percreta be managed conservatively to avoid massive pelvic bleeding and to preserve the patient's fertility. Here, we present a case of placenta percreta diagnosed by magnetic resonance imaging, and...

The third stage of labor is associated with considerable maternal morbidity and mortality. The major complication is postpartum hemorrhage (PPH), which is the leading cause of maternal morbidity and mortality worldwide. Whereas in the event of PPH due to atony of the uterus there exist numerous treatment guidelines; for the management of retained placenta the general consensus is more difficult...

The environment in which the fetus develops is critical for its survival and long-term health. The regulation of normal human fetal growth involves many multidirectional interactions between the mother, placenta, and fetus. The mother supplies nutrients and oxygen to the fetus via the placenta. The fetus influences the provision of maternal nutrients via the placental production of hormones tha...
