Of the approximately 130 million births worldwide each year, four million infants will suffer from birth asphyxia and, of these, one million will die and a similar number will develop serious sequelae. Before being able to develop effective interventions, a better understanding of the pathophysiological mechanisms leading to brain injury and an early identification of babies at high risk for brain injury are required. This study tests the predictivity of traditional and new markers of foetal oxidative stress in relation to neurodevelopmental outcome in 384 newborn infants. The results indicate plasma non protein bound iron as the best early predictive marker of neurodevelopmental outcome, with 100% sensitivity and 100% specificity for good neurodevelopmental outcome at 0-1.16 micro mol/l, and for poor neurodevelopmental outcome at values >15.2 micro mol/l. The number of children with values between 1.16 and 15.2 were 195. Common use of this predictive marker in neonatology units will improve the ability of clinicians to identify those newborn babies who will develop neurodisability.

At low gestational age CA, rather than placental lesions of vasculopathy, negatively impacts perinatal outcome. Clinical significance of histologic vasculopathy remains questionable. Other pathophysiological mechanisms than those associated with placental changes may occur following dysfunction of uteroplacental circulation.

The term "viability" is not simply a synonymous with being "born alive," but is closely related to the capability of having a "meaningful life" and having a reasonable period of survival. The definition of "viability" is generally based on two major criteria: the biological, which takes into consideration the maturity of the foetus, and the epidemiological, which is based on the survival rates reported in literature. The neuromaturation of the cerebral cortex is a dynamic process promoted by the subplate, a transient population of neurons that guides the development of cortical and thalamocortical connections. These connections are for example fundamental for cortical processing of sensory information and mental processes. The first thalamocortical and cortico-cortical connections grows at 23-24 postconceptional weeks, which coincides with the age limit for premature baby survival.

Cranioectodermal dysplasia is a rare syndrome characterized by craniofacial and skeletal anomalies and ectodermal dysplasia. Life-threatening associated conditions (i.e., kidney failure and abnormal regulation of the parathyroid-bone axis) can also develop. We report a patient whose features are suggestive of an inapparent, subtle phenotype of the syndrome. The patient is a 4-year-old girl with only dolichocephaly and clinodactyly; microdontia, hypodontia, and taurodontia (i.e., cone-shaped teeth); anteverted nares, full cheeks, and everted lower lip; epicanthal folds, hypertelorism and hyperopia; and corpus callosum hypoplasia. She has no rhizomelic limb shortening or hair abnormalities. In view of the rarity of the cranioectodermal dysplasias, the variability of the phenotype, and the uncertain outcome of some previously described patients, we believe this inapparent, subtle case should reported to enable better understanding and treatment of this rare syndrome.
