BACKGROUND: Transverse myelitis (TM) is an immune-mediated disorder of the spinal cord that affects adults and children and that causes motor, sensory and autonomic dysfunction. There is a prolonged recovery phase, which may continue for many years. Neuromyelitis optica (NMO) is an uncommon relapsing inflammatory central nervous system condition in which TM can be the first presenting symptom. As TM and NMO affect many patients in the prime of their working life, the disorder can impose a significant demand on health resources...

BACKGROUND AND PURPOSE: Clusters of acute limb weakness in paediatric patients have been linked to outbreaks of non-polio enteroviruses, termed acute flaccid myelitis (AFM). Outside these clusters, in countries where polio is not endemic, this poliomyelitic-like illness is rare in childhood and its natural history is not well defined. We describe presenting features, investigation findings and long-term outcome of a series of children with AFM. METHODS: This was a retrospective cohort study...

Zika virus (ZIKV) is an arbovirus of the Flavivirus genus, and it has an envelope and a single RNA molecule. In early 2016, the World Health Organization declared ZIKV infection to be an emerging global health threat. The major transmission route of the virus to humans is Aedes mosquitoes. ZIKV can be transmitted between humans by transplacental, perinatal, and sexual routes and via blood and body fluids. ZIKV infection usually results in a mild and self-limiting disease with low-grade fever, conjunctivitis, and periorbital edema...

Immune-mediated central nervous system (CNS) demyelinating diseases impact various areas of the brain, optic nerves, and/or spinal cord and can result in a wide range of neurologic symptoms including adverse cognitive outcomes. Neuropsychological outcomes in adult multiple sclerosis (MS) are well documented, while literature on such outcomes in pediatric cohorts is more limited. Furthermore, literature on neuropsychological outcomes in pediatric acute disseminated encephalomyelitis (ADEM), neuromyelitis optica (NMO), and transverse myelitis (TM) is even more limited...

PURPOSE OF REVIEW: Arboviruses have been associated with central and peripheral nervous system injuries, in special the flaviviruses. Guillain-Barré syndrome (GBS), transverse myelitis, meningoencephalitis, ophthalmological manifestations, and other neurological complications have been recently associated to Zika virus (ZIKV) infection. In this review, we aim to analyze the epidemiological aspects, possible pathophysiology, and what we have learned about the clinical and laboratory findings, as well as treatment of patients with ZIKV-associated neurological complications...

INTRODUCTION: Direct intramedullary infections are considered very rare. Only few reports of Staphylococcus aureus myelitis have been published. CASE PRESENTATION: Our patient, a 79-year-old male, presented with a 2-day history of high-grade fever and high inflammatory markers and progressively developed tetraplegia during hospitalization. Lumbar puncture revealed cerebrospinal fluid pleocytosis and a spinal cord MRI revealed transverse myelitis at the level of C3-C5 and possible osteomyelitis of C5-T1...

Understanding the characteristics of neuromyelitis optica spectrum disorder (NMOSD) with recurrent short partial transverse myelitis (SPTM), which is very rare, contributes to the differential diagnosis of multiple sclerosis (MS). We present two Chinese aquaporin-4 immunoglobulin G (AQP4-IgG)-seropositive NMOSD cases who had at least twice SPTM during 4 and 6 years of follow-up, respectively. Their SPTMs have been mild and responded well to corticosteroids just like in the case of MS. The findings highlight the need of searching for serum AQP4-IgG (cell-based assay strongly recommended) in patients with recurrent SPTM and suggest that those patients may have a mild acute attack phase and favorable long-term prognosis...

Chikungunya virus is an alphavirus transmitted by the mosquito Aedes, mainly Aedes aegypti and Aedes albopictus, that can cause acute illness, mostly self-limited, characterized by fever, maculopapular rash, and disabling polyarthritis/arthralgia, with an incubation period of 1 to 12 days. Chikungunya was largely regarded as a non-fatal and self-limited disease, but recently, serious cases have been reported including some with severe involvement of the nervous system, such as meningoencephalitis, myelitis, polyradiculitis, and polyradiculoneuropathy...

We diagnosed a 3-year-old girl with acute transverse myelitis (ATM). She presented with weakness of the limbs and developed urination difficulty and respiratory disturbance. Magnetic resonance imaging revealed a symmetric area of high signal intensity on T2-weighted images involving the lower end of the medulla oblongata to the level of the fourth thoracic vertebra. Anti-aquaporin-4 antibody was negative. She was treated with intravenous methylprednisolone pulse therapy, immunoglobulin therapy, and plasmapheresis; however, her clinical symptoms did not change...

INTRODUCTION: The underlying causes of longitudinally extensive transverse myelitis (LETM) are broad and include inflammatory processes, compression and spinal dural arteriovenous fistula (SDAVF). Presenting symptoms of SDAVF are nonspecific and often go misdiagnosed. Acute clinical deterioration from SDAVF has been described following exertion or valsalva. However, deterioration has been recently recognized following steroid administration and may contribute to increased morbidity. CASE PRESENTATION: We describe a 63-year-old woman with a 2-year history of intermittent lower extremity numbness and back pain, lumbar stenosis, who presented with subacute worsening of symptoms following a course of oral steroids for an upper respiratory infection...

Non-traumatic myelopathies can result from a wide spectrum of conditions including inflammatory, ischemic, and metabolic disorders. Here, we describe the case of a 60-year old immunocompetent woman who developed acute back pain followed by rapidly ascending flaccid tetraparesis, a C6 sensory level, and sphincter dysfunction within 8 h. Acyclovir and steroids were started on day 2 and herpes simplex virus type 2 (HSV-2) was confirmed by polymerase chain reaction in cerebrospinal fluid. Magnetic resonance imaging revealed a bilateral anterior horn tractopathy expanding from C2 to T2 and cervicothoracic cord swelling...

PURPOSE: Transverse myelitis (TM) is an acute inflammatory spinal cord injury. Asymptomatic Chiari I malformation (CMI) management is highly controversial, particularly when associated with a spinal syrinx. Here, we assess the occurrence of CMI in the pediatric TM population and management outcomes. METHODS: We performed a retrospective cohort study based on 61 consecutively identified pediatric TM cases over an -8-year period. We reviewed demographic characteristics, radiographic findings, presenting symptoms, and long-term outcomes...

OBJECTIVE: Elsberg syndrome (ES) is an established but often unrecognized cause of acute lumbosacral radiculitis with myelitis related to recent herpes virus infection. We defined ES, determined its frequency in patients with cauda equina syndrome (CES) with myelitis, and evaluated its clinical, radiologic, and microbiologic features and outcomes. METHODS: We searched the Mayo Clinic medical records for ES and subsequently for combinations of index terms to identify patients with suspected CES and myelitis...

Myelin oligodendrocyte glycoprotein (MOG), a member of the immunoglobulin (Ig) superfamily, is a myelin protein solely expressed at the outermost surface of myelin sheaths and oligodendrocyte membranes. This makes MOG a potential target of cellular and humoral immune responses in inflammatory demyelinating diseases. Due to its late postnatal developmental expression, MOG is an important marker for oligodendrocyte maturation. Discovered about 30 years ago, it is one of the best-studied autoantigens for experimental autoimmune models for multiple sclerosis (MS)...

Data from EV-D68-infected patients demonstrate that pathological changes in the lower respiratory tract are principally characterized by severe respiratory illness in children and acute flaccid myelitis. However, lack of a suitable animal model for EV-D68 infection has limited the study on the pathogenesis of this critical pathogen, and the development of a vaccine. Ferrets have been widely used to evaluate respiratory virus infections. In the current study, we used EV-D68-infected ferrets as a potential animal to identify impersonal indices, involving clinical features and histopathological changes in the upper and lower respiratory tract (URT and LRT)...

BACKGROUND: Enteroviral infections can cause acute flaccid paralysis secondary to anterior myelitis. Magnetic resonance imaging (MRI) is important in the diagnosis of this potentially devastating pediatric disease. Before the 2014 outbreak of Enterovirus D68 (EV-D68), the virus was considered a relatively benign disease. CASE REPORT: A fully immunized 8-year-old boy was brought to the emergency department complaining of a cough, headache, neck pain, and right arm pain and weakness...
