Hematopoiesis in the Fetus and Neonate

Viral Infections in the Fetus and Neonate

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 ...

Cytomegalovirus infection of the fetus and neonate.

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...

Hydronephrosis in the Fetus and Neonate: Causes, Management, and Outcome

The development of circadian rhythms in the fetus and neonate.

The circadian time-keeping system is the neural system that allows predictive adaptation of individuals to the reproducible 24-hour day/night alternations of our planet. A biological clock, the suprachiasmatic nucleus, receives environmental information and imposes a circadian pattern to physiological functions. Since the suprachiasmatic nucleus develops early in gestation and circadian rhythms...

Chapter 8. Skeletal Physiology: Fetus and Neonate

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...
