Objetive: To demonstrate the occurrence of intractable hiccup and nausea (IHN) as first symptoms in Neuromyelitis optica (NMO) patients who developed cervical myelitis. Background: IHN are unique symptoms of NMO, which is a neurological disorder mainly characterized by optic neuritis and myelitis. Methods: We reviewed the medical records of 25 cases of relapsing NMO seen at the Ramos Mejia Hospital in Argentina during the period from 2006 to 2010.

Introduction: Recurrent NMO is an idiopathic inflammatory demyelinating disease of the CNS that preferentially affects the optical nerve and spinal cord. Only recently some studies reported RNMO in pediatric population. Objective: describe the clinical course of pediatric patients diagnosed with RNMO

Anti-aquaporin-4 antibody (NMO-IgG) is used as a diagnostic marker for neuromyelitis optica (NMO). Although the mechanism of spinal cord lesions in NMO has been investigated, that of extensive hemispheric lesions with brain edema remains unclear.

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

Discovery of aquaporin water channel proteins has provided insight into the molecular mechanism of membrane water permeability. In mammalian brain, Aquaporin-4 (AQP4) is the main water channel and is distributed with highest density in the perivascular and subpial astrocyte end-feet. AQP4 is a critical component of an integrated water and potassium homeostasis.

Abstract: Neuromyelitis optica (NMO), or Devic disease, has been distinguished from multiple sclerosis (MS) by the presence of optic neuritis that is usually bilateral, simultaneous, and often severe, myelopathic findings accompanied by longitudinally extensive spinal cord imaging abnormalities, no brain imaging abnormalities typical of MS, and often rapid progression to debility and even death. Researchers at the Mayo Clinic have identified an immunoglobulin marker of NMO (the NMO antibody) that binds selectively to the aquaphorin-4 water channel and may play a causative role

Background: Neuromyelitis optica (NMO) is a rare inflammatory disease. Average age at onset is 35 years. Few data exist on patients with pediatric-onset NMO (p-NMO), with disease onset before age 18 years.

PURPOSE: Recent immunopathologic and MRI findings suggest that tissue damage in neuromyelitis optica (NMO) is not limited to spinal cord and optic nerve, but also in brain.

OBJECTIVE: Resting-state brain activity in neuromyelitis optica (NMO) patients can give clues to the pathophysiology of the disorder, and may be helpful in diagnosis; however, it has been less explored using functional MRI (fMRI). In the current study, we used a regional homogeneity (ReHo) method to investigate NMO-related modulations of neural activity in the resting state. METHODS: Resting-state fMRIs acquired in 17 NMO patients as well as in 17 age- and sex-matched normal controls were compared.
