We report a new syndrome that we call "recurrent optic neuromyelitis with endocrinopathies" in eight Antillean women from Martinique and Guadeloupe Ocular involvement was either monocular or binocular, whereas myelopathy was acute or subacute. In seven patients, myelopathic symptoms recurred, and in six patients, visual problems recurred. Spinal cord(More)
Frontotemporal dementia (FTD), characterized by behavioural and language disorders, is a clinically, genetically and pathologically heterogeneous group of diseases. The most recently identified of the four known genes is GRN, associated with 17q-linked FTD with ubiquitin-immunoreactive inclusions. GRN was analysed in 502 probands with frontal variant FTD(More)
Autosomal dominant cerebellar ataxia type I was diagnosed in three unrelated families from Martinique (French West Indies), and linkage to the locus for spinocerebellar ataxia 2 (SCA2) was established. Neuropathological findings in two patients were those of olivopontocerebellar atrophy without oligodendroglial cytoplasmic inclusions. Cerebellar ataxia was(More)
Highly active antiretroviral therapy (HAART)-induced immune restoration has been very beneficial for acquired immunodeficiency syndrome (AIDS) patients. In rare instances, HAART may induce a paradoxical clinical deterioration due to an immune reconstitution inflammatory syndrome (IRIS). This syndrome has been described with a wide variety of systemic(More)
Idiopathic or primary angiitis of the CNS (PACNS) and cerebral amyloid angiopathy (CAA) are unusual vasculopathies generally regarded as unrelated disorders. A few case reports have, however, described granulomatous angiitis in patients with sporadic, amyloid beta peptide (Abeta)-related CAA. Here we describe the clinical, neuroradiological and(More)
Cerebellar syndromes and radiologic cerebellar atrophy after hyperpyrexia have occasionally been reported, mostly in neuroleptic malignant syndromes, but neuropathologic studies are extremely rare. We studied 3 patients (a 74-year-old woman, a 63-year-old man, and an 80-year-old man) who had heat stroke during heat waves in France. One patient had(More)
The Golgi apparatus plays a key role in the posttranslational processing of polypeptides destined for secretion, incorporation into plasma membranes, and fast axoplasmic transport. Dispersion or fragmentation of the Golgi apparatus, experimentally induced by microtubule-disrupting agents, is associated with decreased secretion of immunoglobulins and(More)
The mechanisms of neuronal apoptosis in prion diseases are unclear. Experimental studies suggest that it may result from 2 associated mechanisms: glutamate-mediated excitotoxicity and oxidative stress. Recent studies showed that activated macrophages/microglia (AMM) express excitatory amino acid transporters (EAATs) in HIV infection, suggesting that they(More)
