Article Synopsis
  • The prevalence of neurodevelopmental disorders (NDD) in France is estimated to be around 15% of births, with premature babies and those with siblings diagnosed with an NDD being at the highest risk.
  • A health promotion policy focused on children and their families is essential, emphasizing early identification of risk factors and supporting both parents and healthcare professionals.
  • Effective prevention and intervention require collaboration among multi-disciplinary teams, ensuring prompt diagnosis and care during the critical "1000 days" developmental period, along with community inclusion and family support initiatives.

Purpose: The purpose of this study was to identify in the EPIRMEX cohort the correlations between MRI brain metrics, including diffuse excessive high signal intensities (DEHSI) obtained with an automated quantitative method and neurodevelopmental outcomes at 2 years.

Materials And Methods: A total of 390 very preterm infants (gestational age at birth≤32 weeks) who underwent brain MRI at term equivalent age at 1.5T (n=338) or 3T (n=52) were prospectively included.

Introduction: SMG9 deficiency is an extremely rare autosomal recessive condition originally described in three patients from two families harboring homozygous truncating SMG9 variants in a context of severe syndromic developmental disorder. To our knowledge, no additional patient has been described since this first report.

Methods: We performed exome sequencing in a patient exhibiting a syndromic developmental delay and in her unaffected parents and report the phenotypic features.

Background: Intraventricular hemorrhage (IVH) is a frequent complication in extreme and very preterm births. Despite a high risk of death and impaired neurodevelopment, the precise prognosis of infants with IVH remains unclear. The objective of this study was to evaluate the rate and predictive factors of evolution to post hemorrhagic hydrocephalus (PHH) requiring a shunt, in newborns with IVH and to report their neurodevelopmental outcomes at 2 years of age.

Unlabelled: Neurodevelopmental outcome in children with agenesis of the corpus callosum (ACC) is correlated with the presence or absence of associated brain abnormalities. Indeed, neurodevelopmental outcome shows severe disabilities when the ACC is not isolated whereas in isolated forms, the neurologic development is mainly normal. Contrary to data in several published studies, the prognosis remains uncertain even in isolated forms, which may lead in France to medical termination of pregnancy.

Objective: Our aim is to assess the neurodevelopmental outcome of children with a prenatal diagnosis of apparently isolated severe ventriculomegaly (SVM).

Method: This is a retrospective cohort study from 1994 to 2011. We included fetuses with unilateral or bilateral ventriculomegaly equal to or greater than 15 mm at prenatal ultrasound and confirmed by magnetic resonance imaging, whose parents chose continuation of pregnancy past 22 weeks, and with no associated findings at diagnosis (i.

Objective: To investigate alteration in 2-year neurological/behavioral outcomes of very preterm infants born in a French level three neonatal intensive care unit.

Methods: We conducted a prospective, comparative study of very preterm infants born before 33 weeks' gestation at 5-year intervals in 2000, 2005 and 2010 at Rouen University Hospital. Neonatal mortality/morbidities, ante- and neonatal treatments, and at age 2 years motor, cognitive and behavioral data were collected by standardized questionnaires.

Aim: To compare neonatal and 2-year outcomes in very premature infants born 5 years apart.

Methods: Prospective observational study of infants born before 33 weeks' gestation in 2000 or 2005 admitted to a neonatal intensive care unit in France. We collected perinatal data and evaluated motor, cognitive, neurosensory and behavioural outcomes at 2 years of age.
