Neuromyelitis optica (NMO or Devic’s syndrome) is a rare autoimmune disease, previously considered a multiple sclerosis variant. The most important laboratory and clinical features are optic myelitis and transverse myelitis, associated with neuromyelitis optica-IgG antibody (NMO-IgG) positivity. Subsequent to this immunological test being available, different groups have described the not-so-rare comorbidity of neuromyelitis optica with other systemic autoimmune diseases, systemic lupus erythematosus with secondary anti-phospholipid syndrome (APS) in particular.
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 severe copper deficiency was revealed.
We report a case of neuromyelitis optica (NMO) with an unusual pattern of remyelination in the spinal cord. A Japanese woman complained of pain and numbness in the left thumb at the age of 36 years
Purpose. To report changes in retinal nerve fiber layer (RNFL) thickness in a patient with neuromyelitis optica (NMO).
Neuromyelitis optica (NMO) is a devastating neuroinflammatory disorder that specifically targets the spinal cord and optic nerves. Aquaporin-4 (AQP4) is the target of the NMO-IgG biomarker
BACKGROUND: Neuromyelitis optica (NMO) is a recurring inflammatory neurological disease characterized by severe optic neuritis and myelitis. The purpose of this study was to determine whether the retinal nerve fiber layer thickness (RNFLT) is correlated with the clinical presentations in patients with NMO and to determine the clinical factors that lead to poor visual outcomes. METHODS: Thirty-five eyes of 18 patients with the NMO spectrum and 28 eyes of 14 patients with multiple sclerosis (MS) were studied.
BACKGROUND: Cases of anti-aquaporin (AQP)-4 antibody-positive familial neuromyelitis optica (NMO) in mothers and daughters are described. 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
Lidocaine unmasks silent symptoms and eases neuropathic pain in multiple sclerosis patients; however, the effects of lidocaine in neuromyelitis optica have never been reported. We describe the case of a 59-year-old Japanese woman with neuromyelitis optica spectrum disorder who developed optic neuritis 1 day after intravenous lidocaine injection for treating allodynia. Her symptom seemed to result from a relapse of neuromyelitis optica induced by lidocaine administration, and not because of the transient effects of intravenous lidocaine administration.
Objective: To analyse clinicoepidemiological features of neuromyelitis optica in a large cohort and to compare the differences between onset age, gender and clinical phenotypes. Methods: Antiaquaporin-4 antibody (AQP4-ab) levels were tested in 2366 serum samples of patients diagnosed as having central nervous system inflammatory demyelinating disorders by their referring physicians. AQP4-ab was measured by indirect immunofluorescence staining using human AQP4-transfected HEK 293 cells.
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
The authors report a case of a 16-year-old girl with a history of systemic lupus erythematosus who developed bilateral acute optic neuritis.
INTRODUCTION: Optic neuromyelitis or Devic’s syndrome is a very rare disease affecting the optic tracts and the spinal cord. Its association with evolving pulmonary tuberculosis has been reported in a handful of case reports.
