The possibility of a therapeutic role for cerebral hypothermia during or after resuscitation from perinatal asphyxia has been a long-standing focus of research. However, early studies had limited and contradictory results. It is now known that severe hypoxia-ischemia may not cause immediate cell death, but may precipitate a complex biochemical cascade leading to the delayed development of neuronal loss. ⋯ Moderate cerebral hypothermia initiated in the latent phase, between one and as late as 6 h after reperfusion, and continued for a sufficient duration in relation to the severity of the cerebral injury, has been consistently associated with potent, long-lasting neuroprotection in both adult and perinatal species. The results of the first large multicentre randomized trial of head cooling for neonatal encephalopathy and previous phase I and II studies now strongly suggest that prolonged cerebral hypothermia is both generally safe - at least in an intensive care setting - and can improve intact survival up to 18 months of age. Both long-term followup studies and further large studies of whole body cooling are in progress.

To evaluate the cross-trimester multiple marker correlation and the minimum marker combination needed for detecting various chromosomal aneuploidies. ⋯ The current study agrees with a previous report that, overall, there is no strong correlation between first and second trimester markers. The extension of the integrated test for detecting various categories of common chromosomal aneuploidies using NT, PAPP-A and uE3 deserves further evaluation.

The neonatal regional tertiary care center of the University of Vienna (VC) has been a member of the Vermont Oxford Neonatal Network (VONN) since 1994. During the period 1994--2002, important differences between the VC and the VONN in both pre- and postnatal management and in late morbidities such as chronic lung disease (CLD) and severe retinopathy of prematurity (ROP) were observed. We hypothesize that stabilization of very-low-birth-weight (VLBW) infants on nasal continuous positive airway pressure (NCPAP) immediately after birth, combined with a restrictive use of artificial ventilation, might be responsible for lower rates of CLD and ROP. ⋯ The association of lower rates of CLD and ROP in the VC compared to the VONN might be related to differences in early respiratory management of VLBW infants at high risk of development of respiratory distress syndrome. This needs to be confirmed in a large multicenter trial.

To document pain expression characteristics in former preterm infants in the first year of life in whom systematic evaluation and treatment of pain was provided. ⋯ Correlations of PCA with pre-procedural and relative increase in heart rate reflect the maturational decrease in heart rate. LOS had an effect on pain expression, potentially reflecting the impact of cumulative 'minor' procedural pain.

Critical congenital cardiovascular malformations (CCVMs) require surgical correction during the first month of life, physical examination is unable to detect >50% of affected infants. An oximetry screening has been previously proposed. Our aim was to verify the usefulness and consistency of a pulse oximetry screening for early detection of CCVMs in a small size nursery. ⋯ Our findings indicate that pulse oximetry is a non-invasive and specific screening tool for an early detection of CCVMs, and is easily applicable to a small size nursery.
