Enterovirus D68 (EV-D68) is a member of the Picornaviridae family. Although EV-D68-associated infection was once considered rare, it has been increasing in recent years. EV-D68 infection is most frequently associated with respiratory illness. However, it has also been implicated in a polio-like neurological disorder, acute flaccid myelitis. Although sialic acid has been implicated in EV-D68 entry, the existence of a protein receptor has yet to be clarified. Here we identify neuron-specific intercellular adhesion molecule 5 (ICAM-5/telencephalin) as a cellular receptor for sialic acid-dependent and -independent EV-D68 viruses...

Subdural arteriovenous fistula (SDAVF) is a rare condition characterized by clinical manifestations ranging from mild bilateral sensory deficits to quadriplegia. The diagnosis is often delayed due to unspecific neurological symptoms, initially diagnosed as polyneuropathy or myelopathy. The diagnosis can be delayed for as long as 1-15 years. The following report describes a cervical SDAVF case initially misdiagnosed as myelitis transversa and treated with intravenous steroids. A 56-year-old male presented with sensory deficits and mild leg and right arm weakness...

Ours was a descriptive observational cross-sectional study carried out in a tertiary care hospital in eastern India over a period of one year to study the profile of neurological involvement in paediatric dengue patients. Of 71 laboratory-confirmed cases, 20 (28.17%) had neurological involvement. Common forms observed were acute encephalopathy (40%), encephalitis (30%), pure motor weakness (15%), transverse myelitis (5%), acute disseminated encephalomyelitis (5%) and Guillain-Barré syndrome (5%). The dengue IgM antibody could be detected in the cerebrospinal fluid of only two patients with encephalitis...

We describe a case of a 25-year-old male with a diagnosis of acute disseminated encephalomyelitis (ADEM) following infection with Campylobacter jejuni, which is implicated in various human pathologies regarding the central nervous system (CNS) with acute course like Guillain-Barré syndrome (GBS), Miller-Fisher syndrome (MFS), Bickerstaff's brainstem encephalitis (BEE), acute transverse myelitis (ATM) as well as ADEM. These conditions are caused by cross-reactivity between Campylobacter's epitopes and cells of the CNS that causes an immunomediated inflammatory demyelination of the CNS...

PURPOSE OF REVIEW: Zika virus (ZIKV) is a mosquito-borne flavivirus that has caused a sudden and explosive outbreak in South America and the Caribbean in the last year, and has been declared a public health emergency by the WHO. As ZIKV afflicts previously naive populations, more severe clinical presentations and sequelae have been observed. A specific emphasis has been placed on the neurological effects in infants resulting from viral exposure in utero. RECENT FINDINGS: Acute onset of ZIKV disease is seen in approximately 20% of cases, whereas most individuals (80%) exposed are asymptomatic...

Longitudinally extensive transverse myelitis (LETM) may be associated with viral triggers, including both infections and vaccinations. We present a case of a healthy immunocompetent 33-year-old woman who developed a hemorrhagic LETM 2 weeks after seasonal influenza vaccination. Hemorrhagic LETM has not to our knowledge been reported after influenza vaccination. It may represent a forme fruste variant of acute hemorrhagic leukoencephalitis.

Demyelinating disorders are very common, but remains isolated to the part of nervous system they involve. However, infrequently, combined involvement of central and peripheral nervous system with demyelinating process have been described. We report one such rare case, with possible theories of common etiological basis. We present a middle aged male patient with Chronic Inflammatory Demyelinating Polyneuropathy(CIDP), who responded to immuno-modulation. Subsequently, he developed Acute Transverse Myelitis (ATM)...

BACKGROUND: Acute transverse myelitis is uncommon and presumably results from an autoimmune process or a preceding infection. Most cases of bacterial myelitis are due to hematogenous dissemination from urinary or respiratory tract infections or contiguous spreading from a neighboring infected structure. A psoas abscess rarely spreads to higher levels of the spinal cord. No cases of acute cervical myelitis due to a psoas abscess have been previously reported. CASE PRESENTATION: A 34-year-old man was transferred to our hospital due to progressive muscle weakness, sensory deficits and severe hypotension...

Acute transverse myelitis is a rare manifestation of dengue infection. To the best of our knowledge, only 6 cases of acute transverse myelitis as a manifestation of dengue infection have been reported thus far. The present study described a case of acute transverse myelitis complicated with subacute thyroiditis 6 days after the onset of dengue viral infection. In addition, the available literature was searched to identify similar previous cases. Treatment with intravenous pulse methylprednisolone immunoglobulin plasmapheresis and physiotherapy resulted in partial recovery at 3 months post-infection...

An 11-year-old boy presented with progressive leg hypesthesia but no history of trauma. Dysuria and constipation appeared subsequent to gait difficulty. He was admitted 8days after onset. Spinal magnetic resonance imaging (MRI) revealed longitudinal hyperintensity with cord swelling and hypointensity on T2-weighted images, suggesting severe inflammation and microbleeding change, respectively. Gadolinium contrast-enhanced MRI demonstrated mild enhancement in the lesions. Platelet count and coagulation findings were normal, and cerebrospinal fluid analysis showed no pleocytosis...

In June and July 2016, we identified 8 adults and 17 children with respiratory enterovirus D68 infections. Thirteen children required intensive care unit admission because of respiratory insufficiency, and 1 had concomitant acute flaccid myelitis. Phylogenetic analysis showed that all of 20 sequences obtained belong to the recently described clade B3.

BACKGROUND: There is substantial overlap between MRI of acute spinal cord lesions from neuromyelitis optica (NMO) and spinal cord infarct (SCI) in clinical practice. However, early differentiation is important since management approaches to minimize morbidity from NMO or SCI differ significantly. OBJECTIVE: To identify MRI features at initial presentation that may help to differentiate NMO acute myelitis from SCI. METHODS: 2 board-certified neuroradiologists, blinded to final diagnosis, retrospectively characterized MRI features at symptom onset for subjects with serologically-proven NMO (N=13) or SCI (N=11) from a single institution...

Radiotherapy is the mainstay of treatment after surgery for high-grade gliomas and is usually well tolerated. Radiation toxicity in the brain is usually classified according to the timing of side effects in relation to treatment, as either acute (during radiotherapy), early delayed (within 12 weeks of radiotherapy) or late delayed (months to years after radiotherapy). We report two cases of young women who developed severe acute demyelination within 4 months of radiotherapy for glioma, one of whom had a previous history of transverse myelitis...
