Stroke Recurrence in First-Ever Symptomatic Carotid Web: A Cohort Study.

Background And Purpose: Carotid web (CaW) is an intimal variant of fibromuscular dysplasia responsible for ipsilateral cerebral ischemic events (CIE). Symptomatic CaW likely has a high risk of recurrent CIE, but no salient prospective data are available. We aimed to assess recurrence rate and its predictors after a first-ever CIE.

SOD1-related ALS with anticipation in a large family from Martinique.

Amyotrophic Lateral Sclerosis (ALS) is a rare neurological disorder that causes degeneration of upper and lower motor neurons and their axons. ALS is mostly sporadic, but there are familial forms. In more than half of the familial forms, a pathogenic variant is found in one of the following genes: , , , , and .

Temporal trends in Human T-Lymphotropic virus 1 (HTLV-1) associated myelopathy/tropical spastic paraparesis (HAM/TSP) incidence in Martinique over 25 years (1986-2010).

Background: Human T-lymphotropic virus type 1 (HTLV-1) has been discovered in 1980 and has been linked to tropical spastic paraparesis (HAM/TSP) in 1985 in Martinique. There is no data on HAM/TSP incidence trends. We report, in the present work, the temporal trends incidence of HAM/TSP in Martinique over 25 years.

Treatment of neuromyelitis optica with rituximab: a 2-year prospective multicenter study.

Objective: Neuromyelitis optica (NMO) is a very severe autoimmune disorder of the central nervous system. It affects young subjects and has a poor prognosis both on a functional and vital level. Therefore, it is imperative to reduce the frequency of relapses.

Pet-directed speech draws adult dogs' attention more efficiently than Adult-directed speech.

Humans speak to dogs using a special speech register called Pet-Directed Speech (PDS) which is very similar to Infant-Directed Speech (IDS) used by parents when talking to young infants. These two type of speech share prosodic features that are distinct from the typical Adult-Directed Speech (ADS): a high pitched voice and an increased pitch variation. So far, only one study has investigated the effect of PDS on dogs' attention.

Easy methods to make the neuronavigated targeting of DLPFC accurate and routinely accessible for rTMS.

Objectives: Dorsolateral prefrontal cortex (DLPFC) is the main stimulation target for rTMS treatment of depression. DLPFC is located in the middle frontal gyrus and corresponds to the lateral part of Brodmann Areas 9 and 46. Current methods to locate the DLPFC are either based on head landmarks that are inaccurate, or based on MRI-neuronavigation.

Effect of interaction type on the characteristics of pet-directed speech in female dog owners.

Recent studies focusing on the interspecific communicative interactions between humans and dogs show that owners use a special speech register when addressing their dog. This register, called pet-directed speech (PDS), has prosodic and syntactic features similar to that of infant-directed speech (IDS). While IDS prosody is known to vary according to the context of the communication with babies, we still know little about the way owners adjust acoustic and verbal PDS features according to the type of interaction with their dog.

One-year disability, death and recurrence after first-ever stroke in a Black Afro-Caribbean population.

Background Few data on stroke outcomes and no data on stroke recurrence are available in Black mono-racial population with high socio-economic status. Aims We investigated outcomes and stroke recurrence at one year in the Black Afro-Caribbean population of Martinique and examined potential predictors of poor prognosis and recurrence. Methods Patients from ERMANCIA II (Etude Réalisée en MArtinique et Centrée sur l'Incidence des Accidents vasculaires cérébraux), a Black population-based and prospective observational study, were followed up at 28-days, three months and one year post stroke.

Association Between Carotid Bulb Diaphragm and Ischemic Stroke in Young Afro-Caribbean Patients: A Population-Based Case-Control Study.

Background And Purpose: Carotid bulb diaphragm (CBD) has been described in young carotid ischemic stroke (CIS) patients, especially in blacks. However, the prevalence of CBD in CIS patients is unknown, and whether CBD is a risk factor for CIS remains unclear. We assessed the association between CBD and incident CIS in a population-based study.

Zika virus detection in urine from patients with Guillain-Barré syndrome on Martinique, January 2016.

We report two cases of Guillain-Barré syndrome who had concomitant Zika virus viruria. This viruria persisted for longer than 15 days after symptom onset. The cases occurred on Martinique in January 2016, at the beginning of the Zika virus outbreak.

MRI characteristics of carotid bulb atypical fibromuscular dysplasia in black stroke patients.

Background And Purpose: In black stroke patients, a particular form of fibromuscular dysplasia (FMD), called atypical FMD (aFMD), is involved in stroke mechanism. The high rate of stroke recurrence under medical treatment leads to propose surgery in such patients. Regarding its location level on the carotid bulb, aFMD is often confused with atherosclerosis or free-floating thrombus.

Carotid-bulb atypical fibromuscular dysplasia in young Afro-Caribbean patients with stroke.

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 included consecutive patients <55 years consulting at Fort-de-France University Hospital Stroke Center (Martinique, FWI) found to have CaFMD as the only cause after a comprehensive work-up.

Trends in incidence and early outcomes in a Black Afro-Caribbean population from 1999 to 2012: Etude Réalisée en Martinique et Centrée sur l'Incidence des Accidents Vasculaires Cérébraux II Study.

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 (ERMANCIA) I and II are 2 sequential prospective population-based epidemiological studies.

Infarction in the anterior choroidal artery territory: clinical progression and prognosis factors.

This study was undertaken to describe the still poorly known evolving profile of anterior choroidal artery (AChA) infarctions, identify their prognosis factors, and evaluate responses to intravenous (IV) thrombolysis. During 42 months, we prospectively enrolled patients with an isolated AChA stroke. Clinical and radiologic parameters were compared between patients with or without progression, defined as any clinical worsening.

Visual field characteristics in neuromyelitis optica in absence of and after one episode of optic neuritis.

Purpose: Optic neuritis (ON) observed during neuromyelitis optica (NMO) is in most cases very severe and with poor prognosis. This study's objective was to analyze visual field (VF) abnormalities observed in the absence of ON and post-ON episode.

Methods: Twenty-seven cases of both NMO and multiple sclerosis (MS) were selected.

Prehospital transfer medicalization increases thrombolysis rate in acute ischemic stroke. A French stroke unit experience.

Objectives: Narrow therapeutic window is a major cause of thrombolysis exclusion in acute ischemic stroke. Whether prehospital medicalization increases t-PA treatment rate is investigated in the present study.

Patients And Methods: Intrahospital processing times and t-PA treatment were analyzed in stroke patients calling within 6h and admitted in our stoke unit.

Efficacy of mitoxantrone in neuromyelitis optica spectrum: clinical and neuroradiological study.

Objective: To evaluate the efficacy of mitoxantrone (MTX) on clinical and neuroradiological parameters of patients who had a relapse of neuromyelitis optica spectrum (NMOS) within the 12 previous months.

Methods: MTX (12 mg/m(2)) combined with methylprednisolone 1 g as three monthly courses followed by three quarterly courses was administered during an observational multicentre open study including 51 consecutive patients (28 NMO, 23 limited forms of NMO) of the French Caribbean and Guyana. The main outcome measure was the reduction of the annualised relapse rate (ARR), and the secondary outcome measures were alteration of disability measured by expanded disability status scale (EDSS) score, the time to onset of the first relapse, and the progression of neuroradiological lesions at 1 year of treatment.
