SETTING: Neuromyelitis optica (NMO), or Devic’s disease, is a rare acute inflammatory disease characterised by demyelination affecting the spinal cord and optic nerves.

This report describes the case of a 71-year-old woman with a limited form of neuromyelitis optica (NMO) who had a longitudinally extensive spinal cord lesion from the fourth to the tenth thoracic vertebrae.

Background: Neuromyelitis optica (NMO) frequently begins with a monofocal episode of optic neuritis or myelitis. A concept named high-risk syndrome (HRS) for NMO has been proposed for patients with monofocal episodes and NMO-IgG antibodies. Objective: To describe HRS patients and compare them with NMO patients

A 21-year-old right-handed woman suffered cervical myelitis in 1971, followed by two episodes of bilateral optic neuritis and four relapses of thoracic or lumbar myelitis through 1998. Her initial brain MRI in 1989 revealed no abnormality, which met the MRI criteria for multiple sclerosis. In 2009, her serum anti-aquaporin-4 antibody was found to be positive, and a diagnosis of relapsing neuromyelitis optica (NMO) was made on the basis of current diagnostic criteria

Background: Recurrent myelitis (rM) represents a pathogenetically heterogeneous group of inflammatory diseases with a selective involvement of the spinal cord. The recent description of NMO Ig-G antibody, the specific biomarker for Neuromyelites Optica (NMO), also in patients with recurrent myelitis with longitudinally extensive transverse spinal cord lesions (LETM), has brought to consider this disease an incomplete form of NMO (NMO Spectrum of Disorders). Methods: we retrospectively selected patients (pts) with rM attended our neurological department between January 2000 and March 2010

Background: Although it has been well established that vaccination does not increase the risk of relapse in patients with multiple sclerosis (MS), no study on the influence of immunization on neuromyelitis optica spectrum disorder (NMOsd) has been conducted. As NMO differs from MS in a number of aspects, including its immunopathogenetic mechanisms, vaccination may have some influence on the occurrence of new relapses

Brain oedema is a major clinical problem produced by CNS diseases (e.g.

Background: Neuromyelitis optica (NMO) is a neurological disease characterized by optic neuritis and transverse myelitis with long spinal cord lesion. Recently, NMO-IgG, which recognizes the aquaporin-4 (AQP-4), was identified in sera from patients with NMO. AQP-4 is a water channel expressed in astrocytes and ependymal cells throughout the brain and spinal cord

May 5, 2010 — Devic’s neuromyelitis optica (DNMO) is a demyelinating disease characterized by bilateral visual disturbance and transverse myelopathy. It was first described in 1894 by Eugene Devic [1] in a woman who suffered from a bilateral optic neuritis and acute transverse myelitis. Pathologically, lesions are restricted to the optic nerves and spinal cord, with areas of necrosis of gray and white matter, cavitations, lack of inflammatory infiltrate, vascular hyalinization, and fibrosis [2]

OBJECTIVE:To investigate the characteristics of the linear lesions and longitudinally extensive spinal cord (LESC) lesions in Chinese patients with neuromyelitis optica (NMO).

Neuromyelitis optica (NMO, Devic’s syndrorne.l is characterized by concurrence of optic neuritis and transverse myelitis, typically associated with a lesion in the spinal cord extending over three or more vertebral segments. It is an inflammatory, demyelinating central nervous system disorder, and although it is most commonly relapsing, it is distinct from multiple sclerosis in that it is more severe, tends to spare the brain, and is associated with a longitudinally extensive lesion on spinal cord MRI. Furthermore, NMO is associated with a highly specific serum autoantibody m,1rker, NMO-lgG, which targets the water channel aquaporin-4.

OBJECTIVE: To analyze treatment response in Brazilian patients with neuromyelitis optica. DESIGN: Retrospective review. SETTING: Neuroimmunology Clinic of the Federal University of Sao Paulo, Sao Paulo, Brazil
