BACKGROUND The increasing survival rates of children who are born very preterm raise issues about the risks of neurological disabilities and cognitive dysfunction. We aimed to investigate neurodevelopmental outcome and use of special health care at 5 years of age in a population-based cohort of very preterm children. METHODS We included all 2901(More)
OBJECTIVES To ascertain the prevalence of newborn encephalopathy in term live births, and also the underlying diagnoses, timing, and outcome at 2 years of surviving infants. DESIGN Population based observational study. SETTING North Pas-de-Calais area of France, January to December 2000. PATIENTS All 90 neonates with moderate or severe newborn(More)
OBJECTIVE To estimate the prevalence of cerebral palsy at 2 years of age among children born very preterm, according to gestational age, infant gender, plurality, and neonatal cranial ultrasound abnormalities. METHODS All infants born between 22 and 32 weeks of gestation in 9 regions of France in 1997 were included in this prospective, population-based,(More)
BACKGROUND Management of neonates with congenital diaphragmatic hernia (CDH) has undergone many changes associated with increased survival of high-risk CDH. However, little is known about the long-term outcome of CDH infants. METHODS Follow-up was performed in 85 newborn infants with CDH admitted in our neonatal intensive care unit between January 1991(More)
OBJECTIVE We sought to (1) evaluate at 2 years the postsurfactant era developmental outcome of children who were born before 33 weeks of gestational age (GA) in the Nord-Pas-de-Calais area in France in 1997 and (2) identify risk factors of poor developmental quotient (DQ). Children were part of the EPIPAGE study, which included all of these births in 9(More)
AIM The aim of this study was to assess the independent role of cerebral lesions on ultrasound scan, and several other neonatal and obstetric factors, as potential predictors of cerebral palsy (CP) in a large population-based cohort of very preterm infants. METHOD As part of EPIPAGE, a population-based prospective cohort study, perinatal data and outcome(More)
OBJECTIVES We compared the frequency of behavioral problems in very preterm and term children at 5 years of age. We hypothesized that behavioral problems would be associated with cognitive impairment and environmental factors and that differences between the 2 groups would be reduced but persist after adjusting for cognitive performance and environmental(More)
OBJECTIVE The purpose of this study was to examine the relationships between different causes of preterm delivery (eg, maternal hypertension, small-for-gestational age [SGA], other) and cerebral damage (eg, cystic periventricular leukomalacia [c-PVL], grade III intraventricular hemorrhage [IVH], and intra-parenchymal hemorrhage [IPH]). STUDY DESIGN This(More)
OBJECTIVE To describe policies towards family visiting in Neonatal Intensive Care Units (NICU) and compare findings with those of a survey carried out 10 years earlier. METHODS A questionnaire on early developmental care practices was mailed to 362 units in eight European countries (Sweden, Denmark, the UK, the Netherlands, Belgium, France, Spain and(More)
AIM To assess cerebral lesions and other medical as well as social characteristics as predictors of risk of mild and severe cognitive deficiencies in very preterm infants. METHODS As part of the EPIPAGE population-based prospective cohort study, perinatal data and cognitive outcome at 5 years of age were recorded for 1503 infants born before 33 weeks of(More)
