Background: Pregnancy in opioid-dependent women is a major public health issue. According to a national household survey in 2001, 3.7% of pregnant women in the United States used illicit drugs. In 2009 this number increased to 4.5% . Women who are afflicted by opioid addiction form a highly vulnerable group of patients frequently facing unplanned pregnancy with adverse outcomes including perina...

coexistence of a viable fetus with a hydatidiform mole is a rare condition and the diagnosis is very important because of the risk of developing severe complications in pregnancy.the management of these pregnancies is optional, although accurate and great care is required to find early signs of maternal or fetal complications. hereby we report a case of dizygotic twin pregnancy with a complete ...

BACKGROUND AND OBJECTIVES Fetus prenatally diagnosed with neck tumors, or with any other disease that obstructs the airways, should not be treated conventionally, as the assistant physician has to face two challenges right after the infant's delivery: the limited time to establish the access to the potentially difficult airways and the lack of anesthesia of the neonate in case of instrumentatio...

The localizations of steroidogenic enzymes (P450scc, 3 beta HSD, P450c17 and P450arom) in testes of Shiba goats were investigated by immunohistochemistry. P450scc, 3 beta HSD, P450c17 and P450arom were detected in all Leydig cells of adults. P450scc and P450c17 were observed in most Leydig cells in the fetus (90 days) and neonate (15 days). 3 beta HSD and P450arom were found in some Leydig cell...

Human CMV infection, the most common virus infection of the fetus and neonate, can occur in utero as "congenital infection" or during the first weeks of life as "perinatal infection." Congenital infection presents either as clinically apparent or as silent infection. Perinatal CMV infection is a common form of CMV acquisition and produces minimal, if any, disease in the full-term infant. The re...

Because of obvious limitations in studying human fetuses and (to a lesser degree) neonates, human regulation of fetal and neonatal mineral homeostasis must be largely inferred from studies in animals. Some observations in animals may not apply to humans. This chapter briefly reviews existing human and animal data, including older studies of surgically manipulated animals and recent studies of m...

Neonates, like older children and adults, are subject to viral infections acquired by horizontal routes, such as those due to influenza, rotavirus, and enteroviruses. They also are at risk for acquisition of viruses through routes that are unique to the perinatal setting where mother-to-child transmission (MTCT) occurs transplacentally, during birth, or from breast milk. The ability of certain ...

Herpes simplex virus can cause serious ocular and systemic disease in the neonate. The mode of transmission to the neonate is usually from the maternal birth canal to the fetus intrapartum; but much more rarely, hematogenous transplacental infection can affect the developing fetus months prior to birth. Persistent fetal vasculature occurs when there is persistence of the fetal ocular vasculatur...
