Extrauterine life duration and ontogenic EEG parameters in preterm newborns with and without major ultrasound brain lesions.

Objective: To determine whether extrauterine life duration is associated with different ontogenic electroencephalographic (EEG) patterns in premature infants compared with neonates born at later gestational ages (GAs).

Methods: We included 97 preterm infants of 24-36 weeks GA. We performed neurosonography and EEG recordings at week 1 and 2 of postnatal life, then every two weeks until term conceptional age (CA).

CNS siderosis and dandy-walker variant after neonatal alloimmune thrombocytopenia.

This report presents a case of superficial siderosis of the central nervous system secondary to repeated intraventricular and subarachnoid bleeding of a newborn infant with neonatal alloimmune thrombocytopenia. In addition, this infant manifested Dandy-Walker variant. To date, the few known cases of superficial siderosis in neonates have not been associated with neonatal alloimmune thrombocytopenia or Dandy-Walker complex.
