Acute necrotizing encephalopathy (ANE) is a rapidly progressive encephalopathy that can occur in otherwise healthy children after common viral infections such as influenza and parainfluenza. Most ANE is sporadic and nonrecurrent (isolated ANE). However, we identified a 7 Mb interval containing a susceptibility locus (ANE1) in a family segregating recurrent(More)
BACKGROUND The mechanisms of childhood and perinatal arterial ischemic stroke (AIS) are poorly understood. Multiple risk factors include cerebral arteriopathy, congenital cardiac disease, infection, sickle cell disease, and maternal-fetal conditions in neonates. For infections and parainfectious conditions being the most important a possible inflammatory(More)
OBJECTIVE We examined cognitive performance in children after stroke to study the influence of age at stroke, seizures, lesion characteristics, neurologic impairment (NI), and functional outcome on cognitive outcome. METHODS This was a prospectively designed study conducted in 99 children who sustained an arterial ischemic stroke (AIS) between the age of(More)
Mutations of the SCN2A gene have originally been described in association with benign familial neonatal-infantile seizures (BFNIS). Recently, single patients with more severe phenotypes and persisting epileptic encephalopathies have been recognized. We report the case of a girl with severe infantile onset epileptic encephalopathy and a de novo missense(More)
The pathogenesis of Mycoplasma pneumoniae encephalitis is not established. We report, for the first time, the case of a patient with severe Bickerstaff brain stem encephalitis in whom we detected intrathecal production of M. pneumoniae-specific antibodies, contrasting the findings in another patient with less severe encephalitis in whom we detected(More)
Rhino-orbito-cerebral mucormycosis is a rare fulminant opportunistic fungal infection that particularly occurs in immunocompromised patients. We present a case of fatal invasive rhino-orbito-cerebral mucormycosis complicated by bilateral thrombotic occlusion of the internal carotid artery with consequent cerebral infarction in a 5-year-old boy after(More)
We report seven children with recent Mycoplasma pneumoniae infection and severe Guillain-Barré syndrome (GBS) that presented to two European medical centres from 1992 to 2012. Severe GBS was defined as the occurrence of respiratory failure, central nervous system (CNS) involvement, or death. Five children had GBS, one Bickerstaff brain stem encephalitis(More)
OBJECTIVE To compare long-term outcome of children and young adults with arterial ischemic stroke (AIS) from 2 large registries. METHODS Prospective cohort study comparing functional and psychosocial long-term outcome (≥2 years after AIS) in patients who had AIS during childhood (1 month-16 years) or young adulthood (16.1-45 years) between January 2000(More)
To determine the neuroimaging pattern of cerebellar dysplasia (CD) and other posterior fossa morphological anomalies associated with mutations in tubulin genes and to perform clinical and genetic correlations. Twenty-eight patients harbouring 23 heterozygous pathogenic variants (ten novel) in tubulin genes TUBA1A (n = 10), TUBB2B (n = 8) or TUBB3 (n = 5)(More)
