A high proviral load of human T cell lymphotropic virus type 1 (HTLV-1) in peripheral blood mononuclear cells (PBMCs) has been reported in patients with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). The aim of the present study was to investigate the role of HTLV-1 proviral load in PBMCs (expressed as the number of copies per 10(6)(More)
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. Awareness of this possible neurological complication of ZikV infection is needed.
Epigenetic modifications of chromatin may play a role in maintaining viral latency and thus persistence of the human T-lymphotropic virus type 1 (HTLV-1), which is responsible for HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP). A major determinant of disease progression is increased peripheral blood proviral load (PVL), possibly via the(More)
The emergence of multiple sclerosis in island societies has been investigated only in a few Caucasian populations living in temperate regions. The effect of human migration on the risk of developing this disease is still an open question because of possible genetic selection. We conducted an epidemiological study of the multiple sclerosis population in the(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)
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)
A 55-year-old man with alcoholism required sigmoid resection for complicated diverticulitis. A few weeks after starting parenteral nutrition, he developed multidirectional gaze nystagmus, gait ataxia, and confusion, leading to the diagnosis of Wernicke encephalopathy. Thiamine treatment was started and his symptoms improved, helping to confirm the(More)
INTRODUCTION Few neurological diseases are linked with anti-glutamic acid decarboxylase antibodies (GAD-ab); stiff man syndrome is an example. Cerebellar ataxia is a new feature of this expanding spectrum. No therapeutic trial is yet available in these diseases. We here report on four patients suffering from cerebellar ataxia linked with GAD-ab and review(More)
We report two cases of encephalopathy (one with seizures, one with electroencephalogram changes) in patients with Zika virus infection. The cases occurred on Martinique in February 2016, during the Zika virus outbreak. Awareness of the various neurological complications of Zika virus infection is needed for patients living in areas affected by Zika virus(More)
