BACKGROUND Few data are available on the relationship between fluid-attenuated inversion recovery vascular hyperintensities and proximal middle cerebral artery occlusion prognosis. OBJECTIVES To assess a fluid-attenuated inversion recovery vascular hyperintensities score (FVHS) and explore its relationship with recanalization status and clinical outcomes(More)
BACKGROUND The severity of envenoming from Bothrops lanceolatus is determined by the development of cerebral, myocardial or pulmonary infarctions, and occasionnaly by serious local envenoming. Introduction of specific antivenom has resulted in a dramatic improvement in the prognosis of this envenoming. Against this background, we report 3 recent cases of(More)
INTRODUCTION Data on epidemiology of neuromyelitis optica (NMO) remained scarce in the last century, but the recent development of diagnostic criteria now enables inclusion of both monophasic and relapsing NMO in epidemiologic studies. Given the rarity of NMO, multicentric studies are needed to confirm a presumed higher frequency in women and in populations(More)
BACKGROUND Despite similarities, neuromyelitis optica (NMO) can be distinguished from multiple sclerosis (MS) by clinical, radiological and serological findings. OBJECTIVE This case-control study aimed to determine whether patients with NMO or with MS in an Afro-Caribbean population originating from French West Indies shared the same or different HLA(More)
Our ability to identify covert cognitive abilities in non-communicating patients is of prime importance to improve diagnosis, to guide therapeutic decisions and to better predict their cognitive outcome. In the present study, we used a basic and rigorous paradigm contrasting pairs of words orthogonally. This paradigm enables the probing of semantic(More)
Ingestion of star fruit (Averrhoa carambola) can induce severe intoxication in subjects with chronic renal failure. Oxalate plays a key role in the neurotoxicity of star fruit. We report the cases of two patients with unknown chronic renal insufficiency who developed severe encephalopathy after ingestion of star fruit. The two patients developed intractable(More)
BACKGROUND AND PURPOSE Seldom studies are available on trends in stroke incidence in blacks. We aimed to evaluate whether stroke risk prevention policies modified first-ever stroke incidence and outcomes in the black Afro-Caribbean population of Martinique. METHODS Etude Réalisée en Martinique et Centrée sur l'Incidence des Accidents Vasculaires Cérébraux(More)
We report a 55-year-old woman with intracranial hypertension due to unilateral extrinsic compression of the left transverse sinus by a meningioma. Because of the high risk of the conventional neurosurgical intervention, she underwent an endovascular procedure consisting of a transstenotic stent placement in the left transverse sinus. One month after(More)
BACKGROUND AND PURPOSE An atypical form of fibromuscular dysplasia located in the internal carotid-bulb (CaFMD) is thought to be uncommon and is poorly described as a cause of ischemic stroke in the young. This study aimed to obtain a better description of CaFMD in Afro-Caribbean population, who could be particularly affected by it. METHODS This study(More)
BACKGROUND AND PURPOSE The aim of the current study was to determine the prevalence of basilar artery hypoplasia (BAH) and to evaluate whether BAH is a possible risk factor for posterior circulation stroke (PCS). METHODS Basilar artery diameter was assessed by MRI in 685 consecutive ischemic stroke patients. BAH frequency, defined as a diameter <2 mm, was(More)
