Nasal continuous positive airway pressure (CPAP) applied shortly after birth is said to be an effective treatment of respiratory distress in very low birth weight infants (VLBW). We tested the hypothesis that the use of early nasal CPAP (applied as soon as signs of respiratory distress occurred, usually within 15 min after birth) reduces the need for(More)
OBJECTIVE To investigate fetal brain development in vivo using early postnatal cranial MRI in term and preterm newborn infants. STUDY DESIGN 51 infants, 1.5-T whole-body system, extremity coil, spin-echo images obtained in all three planes (T1- and T2-weighted). Independent review by two neuroradiologists (blinded for gestational age and medical history)(More)
Smoking during pregnancy results in offspring with an average birth weight 200 g less than those of non-smoking mothers. The pathogenesis of this effect is still unknown and there is no general agreement about the causal relationship between maternal smoking and subsequent fetal growth retardation. In the present study, a model of maternal smoking during(More)
INTRODUCTION Cerebrovascular changes are rarely discussed in patients with hemimegalencephaly. These alterations have previously been associated with epileptical activity. CASE We report the case of a 36-week gestation neonate presenting with total right hemimegalencephaly, as demonstrated by a magnetic resonance imaging (MRI) performed in the first days(More)
Our recently reported animal (rat) model of maternal cigarette smoke exposure during pregnancy is characterized by fetal growth retardation and lung hypoplasia. We have further defined the fetal lungs using quantitative histologic techniques. Compared to controls, lung volume at term is reduced in the experimental animals (0.28 versus 0.33 ml, p less than(More)
PURPOSE To illustrate the evolution of brain perfusion-weighted magnetic resonance imaging (PWI-MRI) in severe neonatal hypoxic-ischemic (HI) encephalopathy, and its possible relation to further neurodevelopmental outcome. MATERIALS AND METHODS Two term neonates with HI encephalopathy underwent an early and a late MRI, including PWI. They were followed(More)
Congenital lung hypoplasia (LH) has been identified with increasing frequency in perinatal and neonatal necropsy reviews. The available prevalence figures have been derived using various diagnostic criteria in different populations and at various times. We therefore reviewed our experience in 15 years of consecutive early neonatal necropsies using one(More)
An animal study to evaluate dual-energy x-ray absorptiometry (DXA) and magnetic resonance (MR) imaging and spectroscopy for measurement of neonatal body composition was performed. Twenty-three piglets with body weights ranging from 848 to 7550 g were used. After measuring total body water, animals were killed and body composition was assessed using DXA and(More)
OBJECTIVE We present the case histories of three premature infants with congenital posthemorrhagic hydrocephalus. STUDY DESIGN The timing of the lesion was monitored in utero in two of the three cases. Magnetic resonance imaging studies (prenatal in one case, within 24 hours of birth in all three cases) established the duration of the lesions and thereby(More)
We studied the effects of alterations in lung fluid volume on growth and maturation of the fetal lung. In a chronic fetal sheep preparation, right fetal lung volume was decreased by drainage of lung fluid while the volume of the left lung was expanded by mainstem bronchus ligation leading to lung fluid retention. After an experimental period of 25 d (from(More)
