Use of near-infrared spectroscopy (NIRS) in cerebral tissue oxygenation monitoring in neonates.

Near-infrared spectroscopy (NIRS) is a technology capable of non-invasive, continuous measuring of regional tissue oxygen saturation (StO). StO represents a state of hemodynamic stability, which is influenced by many factors. Extensive research has been done in the field of measuring StO of various organs.

[Bart´s syndrome associated with epidermolysis bullosa junctionalis and with pyloric atresia. An autopsy case report].

Barts syndrome, in literature also known under the name CLAS (Congenital Localised Absence of Skin), first described by Bart in 1966 as congenital localized absence of skin, epidermolysis bullosa congenita and nail abnormalities. The authors present a macroscopic and histological findings of a newborn with Barts syndrome, with epidermolysis bullosa junctionalis and atresia pylori, who died 17 days after birth and 13 days after surgery for pyloric stenosis.

Very early postnatal changes in splanchnic circulation in term infants.

Background: Reversed blood flow has been reported in the superior mesenteric artery (SMA) in 92% of healthy term newborns at 2 h of age. By 24 h after birth the end-diastolic velocity became positive in all of the infants.

Objective: To characterize hemodynamic changes in the coeliac artery and superior mesenteric artery in healthy term newborns during the first 6 h after birth and to specify the time interval when the negative values of end-diastolic velocity in the superior mesenteric artery become positive.
