The lesion termed 'placental infarction hematoma' is associated with fetal death and adverse perinatal outcome. Such a lesion has been associated with a high risk of fetal death and abruption placentae. The fetal and placental hemodynamic changes associated with placental infarction hematoma have not been reported. This paper describes a case of early and severe growth restriction with preeclam...

Adrenomedullin (AM) is a novel vasorelaxant peptide, isolated from human pheochromocytoma. Although AM may be involved in the regulation of the cardiovascular system, a number of other mechanisms are also involved. The present study was undertaken to confirm the presence of AM in human maternal circulation and in placental function during pregnancy. Immunoreactive (ir) AM concentrations in mate...

Placental mesenchymal dysplasia (PMD) is a rare placental disorder characterized by placental enlargement and areas of abnormal, enlarged, grape-like villi. This condition may resemble a partial hydatidiform mole and may occur associated with Beckwith-Wiedemann syndrome (BWS) or in phenotypically normal fetuses. There were 110 cases reported so far. We describe one case with typical gross and m...

Here the histopathology findings of placental infarction associated with late preterm birth are reported. The subject was a male neonate delivered at 34 weeks and 5 days of gestation with a birth weight of ∼2500 g. His mother had been diagnosed with a threatened premature birth at 27 weeks of pregnancy. The size and weight of the placenta was considered appropriate for gestational age. On the c...

Pregnancy requires a higher functional beta cell mass and this is associated with profound changes in the gene expression profile of pancreatic islets. Taking Tph1 as a sensitive marker for pregnancy-related islet mRNA expression in female mice, we previously identified prolactin receptors and placental lactogen as key signalling molecules. Since beta cells from male mice also express prolactin...

BACKGROUND AND OBJECTIVE Nausea and vomiting are common conditions that occur during early pregnancy and can be disabling. Ondansetron had been used in pregnant women when treatment with conventional antiemetics has failed; however, the safety and tolerability of this relatively new antiemetic drug during pregnancy is still uncertain. The objective of this study was to quantify the placental tr...

INTRODUCTION Young infants are protected from measles infection by maternal measles antibodies. The level of these antibodies at birth depends on the level of antibodies in the mother and the extent of placental transfer. We investigated predictors of levels of measles antibodies in newborns in rural Kenya. METHODS A total of 747 paired maternal-cord serum samples (91 from human immunodeficie...

BACKGROUND Increased stillbirth rates occur among HIV-infected women, but no studies have evaluated the pathological basis for this increase, or whether highly active antiretroviral therapy (HAART) influences the etiology of stillbirths. It is also unknown whether HIV infection of the fetus is associated with stillbirth. METHODS HIV-infected women and a comparator group of HIV-uninfected wome...

UNLABELLED Imprinted genes, which are monoallelically expressed by virtue of an epigenetic process initiated in the germline, are known to play key roles in regulating fetal growth and placental development. Numerous studies are investigating the expression of these imprinted genes in the human placenta in relation to common complications of pregnancy such as fetal growth restriction and preecl...

placenta plays a vital role in normal fetal development and failure of placenta to gain weight and insufficiency of its function can result in fetal disorders. we performed this study to determine placental weight and factors associated with low weight placentas. in a longitudinal cross-sectional study, women with single pregnancy, and gestational age between 37-42 weeks were studied. the subje...
