PARTICIPANTS: The demographic, clinical, neuroimaging, and anti-AQP-4 antibody status were investigated in four patients from two Asian families with anti-AQP-4 antibody-positive NMO. OBSERVATIONS: NMO was diagnosed in both mothers and ...

To evaluate the role of infections in the development of neuromyelitis optica (NMO), 19 patients positive for anti-aquaporin-4 antibody were screened for 24 viral and bacterial infections. Serological evidence of recent viral infection was found in 7 of 15 patients screened during the acute phase of the neurologic illness, which was a significantly more frequent rate of ...

The Focusing DIRC is considered for the Barrel PID at a possible Super-B factory. To reduce sensitivity to background, it would be desirable to reduce a size of the present BaBar photon detector. One way to do it is to replace it with a focusing optics and use smaller photon detector pixels. We have simulated the focusing optics with simulation software based on a 3D calculation performed with the ...

Neurologists commonly use therapeutic plasma exchange (TPE, also known as plasmapheresis or therapeutic apheresis) to treat a number of conditions. This concise review examines the most common neurologic indications for therapeutic plasma exchange. It focuses on Guillain-Barr� syndrome and myasthenia gravis and also the role of TPE in chronic inflammatory demyelinating polyneuropathy, ...

Lyme optic neuritis (ON) is a rare disease and only a few cases have been reported. We describe two cases of isolated Lyme ON, one with recurrence 9 months after the appearance of initial symptoms. Diagnosis criteria for multiple sclerosis and neuromyelitis optica were not met. The etiological diagnosis was based on European case definition criteria for neuroborreliosis. Both ...

This calorimetric technique provides the cosmic ray energy, without resorting to simulations, and atmospheric depth where the shower develops the maximum number of particles, an observable sensitive to the chemical composition of the ...

An aim of the study was to establish MRT signs that may be useful for differential diagnosis of multiple sclerosis (MS). Three groups of patients have been examined: 300 patients with MS, 35 with demyelinating diseases (acute disseminated encephalomyelitis, neuromyelitis optica--Devic's syndrome); 90 patients with systemic autoimmune diseases (systemic lupus erythematosus, ...

The spectrum of idiopathic inflammatory-demyelinating disorders of the CNS is classified based on clinical symptoms and signs, clinical severity, lesion distribution, neuroimaging features and cerebrospinal fluid characteristics. There is a wide variety of conditions in this broad spectrum. In some cases, the dissemination in the CNS is limited to the optic nerves and spinal cord. Neuromyelitis ...

Longitudinally extensive transverse myelitis refers to florid and widespread inflammation of the spinal cord causing T2 hyperintensity on spinal magnetic resonance imaging that is seen to extend over three or more vertebral segments. Whilst rare, longitudinally extensive transverse myelitis is clinically important as it can lead to catastrophic morbidity, and a group of these patients are at risk ...

We reported recently that intracerebral administration of NMO-IgG with human complement produces neuromyelitis optica (NMO) lesions in mice. We examined the role of T cells in the formation of NMO lesions by comparing brain histopathology in wildtype and nude mice. Brains were co-injected with IgG from NMO patients and human complement. At 24h and 5days, wildtype vs. nude ...

A 53-year-old man presented with optic neuritis, followed within 10 weeks by a subacute progression of weakness, ataxia, and multiple cranial nerve palsies. Cranial magnetic resonance imaging demonstrated multiple T2-hyperintense lesions extending from the ponto-medullary junction to the thalamus and internal capsule. Cerebrospinal fluid analysis showed lymphocytic pleocytosis with elevated ...

Since the description of the association between neuromyelitis optica (Devic's disease) and aquaporin 4 IgG antibody (NMO-IgG), the search for this antibody has been considered a highly recommended laboratory test when centromedullary multisegmental lesions are observed by magnetic resonance imaging (MRI). Such MRI lesions have not been confined to acute NMO myelitis because ...

The discovery of persistent transmissible agents by veterinarians has led to striking advances in the infectious cause of neuropathies of human beings. There is evidence for persisting infection in congenital rubella and the herpes group of viruses including cytomegalovirus infections. Hepatitis types A and B are candidates for inclusion in the category of persisting viral infections. The rubeola ...

A pregnant woman with extensive brain lesions on magnetic resonance imaging was tested positive for anti-aquaporin4 (AQP4) antibodies. An open biopsy of the left temporal lobe showed pathological changes in both the white and gray matter. Hematoxylin and eosin, Kl�ver-Barrera, and myelin basic protein staining results were indicative of demyelination in the white matter. Loss of AQP4 and glial ...

The curve-fitting technique incorporates independently measured values for the film surface roughness, film thickness, and incident ...

Acute demyelinating optic neuritis in children can occur in isolation or be associated with acute disseminated encephalomyelitis, multiple sclerosis or neuromyelitis optica. Clinical features, neuroimaging, cerebrospinal fluid findings and long term prognosis were reviewed in 26 children diagnosed with optic neuritis at the first presentation of demyelinating disease. The risk ...

We report two patients, both with a history of gastric surgery, who presented with progressive optic neuropathy and myelopathy. The patients' symptoms were initially attributed to vitamin B12 deficiency and/or neuromyelitis optica; however, after the neurologic deficits continued to progress with the use of conventional treatments, further evaluation was initiated, and a ...

We report a 13-year-old girl diagnosed with neuromyelitis optica (NMO). We also report that plasma exchange could be performed early in her clinical course as well as her good response to this treatment. At the onset, transient numbness of both upper extremities appeared. Approximately one month thereafter, photesthesia of the left eye disappeared and she visited our hospital. ...

Zamboni et al proposed a new hypothesis for the pathomechanisms of multiple sclerosis (MS): chronic cerebrospinal venous insufficiency (CCSVI). Using Doppler ultrasound and venograms, they found severe extracranial venous stenosis in MS patients. They suggested that a venous obstruction in the neck caused a reflux back into the brain, which led to edema and demyelination. We examined the blood ...

An 84-year-old man presented with acute bilateral visual impairment 2 weeks after an upper respiratory tract infection. A few days later, he developed left hemiparesis, followed by paraplegia. The brain magnetic resonance imaging (MRI) showed high-intensity lesions in the right cerebellum, pons, left and right corona radiata, and right putamen. The diffusion weighted image also showed these ...

BackgroundNeuromyelitis optica (NMO) is an inflammatory demyelinating disease that predominantly affects the optic nerves and the spinal cord, and is possibly mediated by an immune mechanism distinct from that of multiple sclerosis (MS). Central scotoma is recognized as a characteristic visual field defect pattern of optic neuritis (ON), however, the differing pathogenic ...

BackgroundGlial fibrillary acidic protein (GFAP) is a specific intermediate filament of the cytoskeleton of the astrocyte and may be used as a specific marker for astrocytic damage. It is detectable in the cerebrospinal fluid following a relapse caused by Multiple Sclerosis (MS) and Neuromyelitis Optica (NMO) spectrum disease. Higher levels are found following an NMO-related ...

BackgroundNeuromyelitis optica is a central nervous system demyelinating and inflammatory syndrome. The objective of this study is to identify cytokines related to the cellular immune response as well as blood brain barrier integrity and oxidative stress.MethodsWe performed a molecular characterization of cellular immune response and oxidative stress in serum from ...

Background The identification of biomarkers able to improve the differential diagnosis between multiple sclerosis (MS) and neuromyelitis optica (NMO) is challenging because of a different prognosis and response to treatment. Growing evidence indicates that brain and CSF N-acetyl aspartate (NAA) concentration is a useful marker for characterising different phases of axonal ...

Selective aquaporin-4 (AQP4) loss and vasculocentric complement and immunoglobulin deposition are characteristic of neuromyelitis optica (NMO). We recently reported extensive AQP4 loss in demyelinated and myelinated layers of Bal�'s lesions without perivascular immunoglobulin and complement deposition. We aimed to reappraise AQP4 expression patterns in NMO and multiple ...

Neuromyelitis optica (NMO) is a severe demyelinating disease defined principally by its selective effect on the optic nerves and spinal cord. Contemporary diagnostic criteria require an absence of any clinical disease outside the optic nerve or spinal cord. However, we frequently encounter patients with NMO who have previously undetected symptomatic brainstem lesions. We ...

Both general neurologists and neurologists with a broad spectrum of subspecialty interests are often asked to evaluate patients with disorders of the spinal cord. Over the past decade, there have been significant advances in our understanding of a wide spectrum of immune-mediated, infectious, metabolic, hereditary, paraneoplastic, and compressive myelopathies. Advances have been made in the ...

PURPOSE: To investigate the presence of an ethnicity bias within patients presenting with optic neuritis in London. DESIGN: Observational cross-sectional study.

OPINION STATEMENT: Neuromyelitis optica (NMO) or Devic's disease typically involves the optic nerves and the spinal cord and is most often relapsing. The pathogenesis is one of an acute inflammatory process targeting astrocytes and resulting in demyelination, as well as axonal injury. In a high proportion of recognized cases of NMO, there is a highly specific autoantibody ...

In the past 10 years, neuromyelitis optica (NMO) has evolved from Devic's categorical clinical description into a broader disease spectrum. Serum IgG antibodies have been identified in NMO patients with the water channel aquaporin-4 (AQP4) as their main target antigen. AQP4 antibodies/NMO-IgG have been shown to be a highly specific and moderately sensitive serum biomarker for ...

Background:? Oxidative stress plays a central role in neuropathology of multiple sclerosis (MS). The patients with MS have low antioxidant status. Antioxidant therapy may represent an attractive treatment of MS. However, the relationship between neuromyelitis optica (NMO), a distinct nosologic entity or a form of MS, and antioxidant status has not fully been investigated. ...

Neuromyelitis optica (NMO) is an inflammatory demyelinating disorder characterized by optic neuritis and acute myelitis. A parainfectious pathogenesis may play a partial role in the development of this disorder. Several viral infections are known to cause NMO. Here we report the case of a 15-year-old girl diagnosed with postinfluenza monophasic NMO. The patient developed ...

Until recently, neuromyelitis optica (NMO) was considered to be a sub-type of multiple sclerosis (MS), which has a strong predilection for Caucasian populations, whereas NMO is more frequent in non-Caucasian individuals. The objective of this study was to compare the HLA-DRB profile in Brazilian Mulatto patients with NMO spectrum disorders (NMOSDs) with that observed for ...

Background: Neuromyelitis optica (NMO) is a disease with autoimmune characteristics. A genetic autoimmune dependency for NMO has not been clarified in detail. Objective: To investigate immunogenetic aspects of NMO. Methods: Forty-one patients with NMO and 42 patients with multiple sclerosis (MS) were diagnosed in a population-based Caucasian cohort. HLA DQA1, DQB1, and DRB1 ...

OBJECTIVE:Autoantibodies to aquaporin-4 (AQP4) are specific and pathogenic for neuromyelitis optica (NMO). Therefore, we evaluated whether AQP4 single-nucleotide polymorphisms (SNPs) are associated with susceptibility to NMO or whether mutations that potentially alter AQP4 structure or expression are present in some patients. METHODS:We genotyped 8 AQP4 SNPs chosen based on ...

Background: A new autoantibody (termed NMO-IgG, or AQP4-Ab) has recently been described in patients with neuromyelitis optica (NMO) and its formes frustes, longitudinally extensive transverse myelitis (LETM) and recurrent optic neuritis (rON). However, AQP4-Ab has been found also in patients with co-existing rheumatic diseases such as systemic lupus erythematosus (SLE) or ...

The objective of this study investigated cognitive impairments and their correlations with fractional anisotropy (FA) and mean diffusivity (MD) in patients with neuromyelitis optica (NMO) without visible lesions on conventional brain MRI during acute relapse. Twenty one patients with NMO and 21 normal control subjects received several cognitive tests to assess cognitive ...

BackgroundIn 70-80% of cases, neuromyelitis optica (NMO) is associated with highly specific serum auto-antibodies to aquaporin-4 (termed AQP4-Ab or NMO-IgG). Recent evidence strongly suggests that AQP4-Ab are directly involved in the immunopathogenesis of NMO.ObjectiveTo assess the frequency, syndrome specificity, diagnostic relevance, and origin of cerebrospinal fluid (CSF) ...

Background: Although brain abnormalities are being recognized more frequently in patients with neuromyelitis optica spectrum disorder (NMOSD), most brain lesions in previous reports have accompanied pre-existing NMOSD. Here, we describe clinical and imaging characteristics of patients with NMOSD who presented with brain symptoms as their first manifestation of the condition. ...

Aquaporin-4 (AQP4) is a water-selective transporter expressed in astrocytes throughout the central nervous system, as well as in kidney, lung, stomach and skeletal muscle. The two AQP4 isoforms produced by alternative spicing, M1 and M23 AQP4, form heterotetramers that assemble in cell plasma membranes in supramolecular structures called orthogonal arrays of particles (OAPs). Phenotype analysis of ...

Water channel aquaporin-4 (AQP4) is expressed in astrocytes throughout brain and spinal cord. Two major AQP4 isoforms are expressed, M1 and M23, having different translation initiation sites. A longer isoform (Mz) has been reported in rat with translation initiation 126-bp upstream from that of M1. By immunoblot analysis of SDS and native gels probed with a C-terminus anti-AQP4 antibody, Mz was ...

Devic�s neuromyelitis optica (DNMO) is a demyelinating and inflammatory disease of the central nervous system (CNS) essentially restricted to the spinal cord and the optic nerves. It is a rare disorder with a prevalence estimated at less than 1/100,000 in Western countries. Since the first description by Eug�ne Devic in 1894, the relationship between DNMO and multiple ...
