IMPORTANCE Most patients with neuromyelitis optica (NMO) and many with NMO spectrum disorder have autoantibodies against aquaporin-4 (AQP4-Abs), but recently, myelin-oligodendrocyte glycoprotein antibodies (MOG-Abs) have been found in some patients. Here, we showed that patients with NMO/NMOSD with MOG-Abs demonstrate differences when compared with patients(More)
IMPORTANCE Aquaporin 4 antibody (AQP4-Ab)-negative patients with longitudinally extensive transverse myelitis (LETM) behave differently from those with AQP4-Ab. Aquaporin 4 antibody-negative neuromyelitis optica (NMO) is rare when good assays are used. OBJECTIVE To assess if AQP4-Ab-negative patients with LETM share similar disease characteristics with(More)
Neuromyelitis optica and neuromyelitis optica spectrum disorders have been recently associated with the disease-specific autoantibody aquaporin-4, thought to be pathogenic. Identifying this antibody has allowed the clinical phenotype to be broadened. It is clear that some patients with similar clinical features do not have this antibody and may have a(More)
BACKGROUND Neuromyelitis optica (NMO) is a severe autoimmune inflammatory disorder associated with considerable relapse-related disability. Immunosuppression is the mainstay of treatment but many patients do not tolerate first-line immunosuppressive agents, or experience ongoing relapses. OBJECTIVE To evaluate the effectiveness and tolerability of(More)
Olfactory dysfunction is common in multiple sclerosis (MS). Olfactory bulb and tract pathology in MS and other demyelinating diseases remain unexplored. A human autopsy cohort of pathologically confirmed cases encompassing the spectrum of demyelinating disease (MS; n = 17), neuromyelitis optica [(NMO); n = 3] and acute disseminated encephalomyelitis(More)
BACKGROUND Modafinil is a wakefulness-promoting drug used to treat narcolepsy, obstructive sleep apnoea, and shift-work sleep disorder. Modafinil has also been used for the treatment of fatigue and excessive sleepiness in other neurological disorders including multiple sclerosis, psychiatric disorders, and for cognitive enhancement. Recent preclinical(More)
This study is an analysis of 70 children, five months to eleven years of age, with hydrocephalus secondary to tuberculous meningitis. They presented as an acute illness, mostly in early childhood, with disturbance of consciousness, convulsions, rigidity and, sometimes, neurological deficit. CT scans showed ventricular dilatation, periventricular(More)
OBJECTIVE To investigate the association between neuromyelitis optica spectrum disorder (NMOSD) and pregnancy outcome. METHODS An international cohort of women with aquaporin-4 antibody-positive NMOSD and ≥1 pregnancy was studied retrospectively. Multivariate logistic regression was used to investigate whether pregnancy after NMOSD onset was associated(More)
This paper focuses on the Routing and Spectrum Allocation (RSA) problem in Coherent Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) Elastic Optical Networks (EON) with consideration of transmission impairments. A majority of the literature in EON is based on improving the spectral efficiency and efficient utilization of available spectral(More)
