Biodynamic lighting conditions preserve nocturnal melatonin production in pregnant women during hospitalization: A randomized prospective pilot study.

Background And Purpose: Maternal circadian rhythms are important for maintaining maternal and fetal homeostasis. The maternal circadian system coordinates the internal clock of the fetus with environmental lighting conditions the melatonin signal. The intensity and wavelength of daylight influence nocturnal melatonin production.

Blood pressure and kidney function in neonates and young infants with intrauterine growth restriction.

Background: Intrauterine growth restriction (IUGR) has been associated with changes in kidney anatomy, nephrogenesis and the vascular system, resulting in secondary arterial hypertension and kidney damage in adulthood. Here, we compare routine clinical and metabolic parameters between IUGR and non-IUGR study participants in the neonatal and early infant period.

Methods: A total of 39 IUGR and 60 non-IUGR neonates were included during an 18-month study period.

Congenital diaphragmatic hernia in a case of Cat eye syndrome.

Our findings extend the phenotypic spectrum of Cat eye syndrome, a disorder with wide clinical variability. The potentially life-threatening complications of congenital diaphragmatic hernia should be considered in genetic counseling and prenatal diagnostic.
