Perinatal inflammation exposure and developmental outcomes 7 years after neonatal arterial ischaemic stroke.

Aim: To test the association between perinatal inflammation exposure and Full-Scale IQ (FSIQ) score 7 years after neonatal arterial ischaemic stroke (NAIS).

Method: We conducted a cross-sectional ancillary study nested in a multicentric longitudinal French cohort of infants born at term with NAIS between November 2003 and October 2006. Seventy-three children were included (45 males, 28 females).

Association of transcallosal motor fibres with function of both hands after unilateral neonatal arterial ischemic stroke.

Aim: The objective of this study was to investigate the involvement of the motor fibres of the corpus callosum after unilateral neonatal arterial ischemic stroke (NAIS) of the middle cerebral artery territory and the relationship to both ipsilesional and contralesional hand function.

Method: Using high-resolution structural magnetic resonance imaging (MRI), functional MRI, and magnetic resonance diffusion-tractography, we compared the midsagittal area of the motor part of the corpus callosum (defined by the fibres connecting the precentral gyri) between 33 7-year-old children after unilateral NAIS and 31 typically developing 7-year-old children. Hand motor performance was assessed by the box and blocks test.

Secondary Prevention of Childhood Arterial Ischemic Stroke.

This study aimed to know how frontline physicians in France, Belgium, and Switzerland implement guidelines regarding the secondary prevention of childhood arterial ischemic stroke and to introduce physicians' point of view on a clinical trial assessing the efficacy of aspirin as a preventive strategy. The authors conducted an online survey directed at specialists throughout dedicated networks and used a mixed method for data analysis. Overall, 63 physicians responded, and 88% prescribe aspirin when sickle cell disease, cardio-embolic stroke, and dissection of cervical arteries are excluded.

MR angiography findings in infants with neonatal arterial ischemic stroke in the middle cerebral artery territory: A prospective study using circle of Willis MR angiography.

Aim: Neonatal arterial ischemic stroke (NAIS) results from a focal disruption of the blood flow in a cerebral artery by a not well understood mechanism. Our objective is to describe the acute MRangiography (MRA) findings in infants with an NAIS in the middle cerebral artery (MCA) territory and correlate them with early parenchymal infarcts and motor outcome.

Methods: Among one hundred prospectively followed neonates with NAIS, we studied thirty-seven patients with an MCA infarct explored with circle of Willis MRA.

Does Contralesional Hand Function After Neonatal Stroke Only Depend on Lesion Characteristics?

Background And Purpose: In children having suffered from neonatal arterial ischemic stroke, the relationship between contralesional hand performance and structural changes in brain areas remote from the infarct site was examined.

Methods: Using voxel-based morphometry, we correlated contralesional gross manual dexterity assessed by the box and block test and whole-brain gray and white-matter volume changes on high-resolution magnetic resonance imaging in 37 7-year-old post-neonatal arterial ischemic stroke children. We also compared the volume of the identified structures with magnetic resonance imaging data of 10 typically developing age-matched children.

Multimodal Outcome at 7 Years of Age after Neonatal Arterial Ischemic Stroke.

Objectives: To evaluate the epileptic, academic, and developmental status at age 7 years in a large population of term-born children who sustained neonatal arterial ischemic stroke (NAIS), and to assess the co-occurrence of these outcomes.

Study Design: A cohort study including 100 term newborns with NAIS was designed. Two infants died during the neonatal period, 13 families were lost to follow-up, and 5 families declined to participate in this evaluation.

Long term motor function after neonatal stroke: Lesion localization above all.

Motor outcome is variable following neonatal arterial ischemic stroke (NAIS). We analyzed the relationship between lesion characteristics on brain MRI and motor function in children who had suffered from NAIS. Thirty eight full term born children with unilateral NAIS were investigated at the age of seven.

Motor outcomes after neonatal arterial ischemic stroke related to early MRI data in a prospective study.

Objective: We aimed to correlate early imaging data with motor outcomes in a large, homogeneous, cohort of infants with neonatal (diagnosed before 29 days of life) arterial ischemic stroke (AIS).

Methods: From a prospective cohort of 100 children with neonatal AIS, we analyzed the MRI studies performed within the 28 first days of life for 80 infants evaluated at 2 years of age. The relationships between infarction location and corticospinal tract (CST) involvement and motor outcomes were studied

Results: Seventy-three infarctions involved the middle cerebral artery (MCA) territory.

Lipoprotein (a), birth weight and neonatal stroke.

Background: Elevated lipoprotein (Lp) (a) is the most common genetically determined risk factor found in babies with perinatal ischemic stroke. The influence of maternal Lp(a) has not been studied extensively to date.

Objectives: To investigate the role of Lp(a) in our population of neonates with stroke.

Obstetrical and neonatal characteristics vary with birthweight in a cohort of 100 term newborns with symptomatic arterial ischemic stroke.

Objectives: Many questions remain regarding the mechanism of perinatal stroke.

Methods: In a series of 100 prospectively enrolled term neonates with symptomatic arterial ischemic stroke, we explored family antecedents, pregnancy and delivery conditions and clinical presenting features and distinguished features of the 50 larger infants with the remainder. Cardiac and cervical arterial imaging were performed in 70 and 51 cases.
