Les accidents vasculaires cérébraux du nouveau-né et de l’enfant

The clinical presentation, risk factors, causes, vital or functional prognosis, and acute management options for stroke occurring in neonates and children are specific, differing from those observed in young adults. Compared with the adult population, less is known about the epidemiology of stroke in the under-18 population where the disease could become more frequent because of advances in both neonatal resuscitation techniques for cerebral disorders and neuroimaging techniques enabling the diagnosis of small lesions. Clinical features are often delayed, especially in neonates, and unlike epilepsy or dystonia of the affected limb, which are frequent complications, aphasia is rather rare. T…

Comparative epidemiology of stroke and acute myocardial infarction: the Dijon Vascular Project (DIVA)

Despite a common pathophysiological mechanism (ie, atherosclerosis) and similar vascular risk factors, few reliable studies have compared the epidemiology of stroke and acute myocardial infarction (AMI).All first ever cases of stroke and AMI in Dijon, France (151 846 inhabitants) from 2001 to 2006 were prospectively recorded. The 30 day case fatality rates (CFRs) and vascular risk factors were assessed in both groups.Over the 6 years, 1660 events (1020 strokes and 640 AMI) were recorded. Crude incidence of stroke was higher than that of AMI (112 vs 70.2/100 000/year; p0.001). With regard to sex, the relative incidence of stroke compared with AMI was 0.88 (95% CI 0.60 to 1.29; p = 0.51) in w…
