International Paediatric Stroke Study: stroke associated with cardiac disorders.

Background And Hypothesis: The aetiologies of arterial ischaemic stroke in children are diverse and often multifactorial. A large proportion occurs in children with cardiac disorders. We hypothesized that the clinical and radiographic features of children with arterial ischaemic stroke attributed to cardiac disorders would differ from those with other causes.

Interrater reliability of the Pediatric National Institutes of Health Stroke Scale (PedNIHSS) in a multicenter study.

Background And Purpose: Stroke is an important cause of death and disability among children. Clinical trials for childhood stroke require a valid and reliable acute clinical stroke scale. We evaluated interrater reliability (IRR) of a pediatric adaptation of the National Institutes of Health Stroke Scale.
