Some strains of West Nile virus (WNV) are neuroinvasive and may induce fatal encephalitis/meningitis in a variety of animal species including humans. Whether, however, there is a strain-specific signature in the brain is as yet unknown. Here we investigated the neuropathogenesis induced by two phylogenetically distant WNV strains of lineage 1, WNV(IS98) and WNV(KUN35 911). While four-week old C...
In recent years, advances in the diagnosis and treatment of herpes simplex encephalitis (HSE) have been achieved due to the prevalence of antiviral drugs and the introduction of the polymerase chain reaction (PCR) to test the cerebrospinal fluid. The several clinical forms of herpes simplex virus type 1 (HSV-1) infections of the central nervous system (CNS), including acute disseminated encepha...
AIMS To investigate if two important epidemic viral encephalitis in children, Enterovirus 71 (EV71) encephalomyelitis and Japanese encephalitis (JE) whose clinical and pathological features may be nonspecific and overlapping, could be distinguished. METHODS Tissue sections from the central nervous system of infected cases were examined by light microscopy, immunohistochemistry and in situ hyb...
purpose: to report a case of acute retinal necrosis following herpetic encephalitis. case report: a 25-year-old male presented with pain and visual loss in his left eye. he had herpetic encephalitis 1 month prior to the visual symptoms. ophthalmologic examination and paraclinical evaluation disclosed acute retinal necrosis. conclusion: herpetic encephalitis may be a risk factor for acute retina...
Opsoclonus is a dyskinesia consisting of involuntary, arrhythmic, chaotic, multidirectional saccades, without intersaccadic intervals. We used a magnetic scleral search coil technique to study opsoclonus in two patients with paraneoplastic complications of lung carcinoma. Eye movement recordings provided evidence that opsoclonus is a three-dimensional oscillation, consisting of torsional, horiz...
Herpes simplex encephalitis (HSE) is one of the commonest viral brain disorders of immunocompetent individuals, with an annual incidence estimated at between 1 in 250 000 and 1 in a million of the population. Most cases are due to herpes simplex virus (HSV) type 1; up to 10% may be caused by HSV-2. Encephalitis is postulated to occur as a consequence of centripetal spread of virus from sites of...
Western equine encephalitis virus (WEEV; Alphavirus) is a mosquito-borne virus that can cause severe encephalitis in humans and equids. Previous studies have shown that intranasal infection of outbred CD-1 mice with the WEEV McMillan (McM) strain result in high mortality within 4 days of infection. Here in vivo and ex vivo bioluminescence (BLM) imaging was applied on mice intranasally infected ...
seen in stroke but with hypometabolism possibly representing a phenomenon of diaschisis. Serial FDG-PET examinations showed markedly increased activity in the basal ganglia as compared with that in the cortex when extrapyramidal features were prominent, which normalised after improvement of this movement disorder. In the setting of paraneoplastic neurological syndrome, FDG-PET imaging can be of...
Enterovirus 71 (EV71) typically causes uncomplicated hand foot and mouth disease in young children. However, a minority of patients may develop neurological complications that include brainstem encephalitis, acute flaccid paralysis, encephalomyelitis, encephalitis and pulmonary oedema. In the wake of near complete global polio eradication, EV71 has emerged as a significant infectious cause of s...
Santa Casa de Belo Horizonte, Belo Horizonte MG, Brazil: MD, PhD, Department of Neurology.; MD, Department of Neurology. Mycoplasma pneumoniae is a frequent cause of respiratory infection in humans, especially schoolchildren, adolescents and young adults, accounting for about 20% of cases of pneumonia in this age group. However, little is known about its extrapulmonary manifestations, with the ...
