Acute encephalitis with refractory, repetitive partial seizures (AERRPS): a peculiar form of childhood encephalitis. Acta Neurol Scand: 2010: 121: 251,256. © 2009 The Authors Journal compilation © 2009 Blackwell Munksgaard. Objective,,, We conducted a nationwide multicenter study in Japan to elucidate the clinical and laboratory characteristics of acute encephalitis with refractory, repetitive partial seizures (AERRPS). Materials and methods,,, Clinical and laboratory features, treatment, and outcome were assessed using a structured questionnaire. Results,,, Twenty-nine children were enrolled in the study. Refractory and repetitive partial seizures accompanied by fever were the cardinal clinical features. Partial seizures consisted principally of eye deviation or facial twitching, being periodically repeated during the acute phase. These seizures were refractory to conventional anticonvulsants and were only suppressed by high-dose intravenous barbiturate administration. Rhythmic activities on electroencephalography and non-specific cerebral atrophy on neuroimaging were common. Serum or cerebrospinal antibodies against GluR,2 were positive in six patients. General prognosis was unfavorable due to intractable epilepsy and cognitive deficits. Conclusion,,, Based on the peculiar and homogenous features, AERRPS can be regarded as a distinct clinical entity. [source]

Epidemiological study of acute encephalitis in Tottori Prefecture, Japan

EUROPEAN JOURNAL OF NEUROLOGY, Issue 10 2008
K. Wada-Isoe
Background and purpose:, To conduct an epidemiological survey of acute encephalitis focusing on non-herpetic acute limbic encephalitis (NHALE) in Tottori Prefecture, western area of Japan. Methods:, A questionnaire survey on the annual number of patients aged 16 years or more with acute encephalitis from 2001 to 2005 was undertaken in 2006. Results:, During the study period, 49 patients were diagnosed with acute encephalitis. The subtype of acute encephalitis was as follows: 10 patients with herpes simplex encephalitis (HSE), 12 patients with NHALE, 4 patients with paraneoplastic encephalitis, 2 patients with encephalitis associated with collagen disease, one patient with viral encephalitis other than HSE, 20 patients with encephalitis with unknown causes. The service-based incidence rate of acute encephalitis was 19.0 per million person-years. The incidence rate of NHALE subtype was 4.7 per million person-years. Conclusions:, Our epidemiological survey indicated an estimated 550 patients would develop NHALE per year in Japan, suggesting that NHALE may not be a rare disorder. [source]

Two Patients With Imported Acute Neuroschistosomiasis Due to Schistosoma mansoni

JOURNAL OF TRAVEL MEDICINE, Issue 4 2010
Laure Houdon MD
We report the case of two brothers who returned from Madagascar presenting all the acute phase symptoms of a primary invasive Schistosoma mansoni infection, together with brain involvement characterized by acute encephalitis. This rarely described issue should be considered in travelers returning from endemic areas with acute neurological symptoms. [source]

Contemporary encephalitis lethargica presenting with agitated catatonia, stereotypy, and dystonia-parkinsonism

MOVEMENT DISORDERS, Issue 15 2007
Russell C. Dale PhD
Abstract Encephalitis lethargica (EL) syndrome was classically described by Von Economo and has somnolent-ophthalmoplegic, hyperkinetic, and amyostatic-akinetic forms. We describe 2 recent cases of EL characterized by an acute encephalitis with mixed movement disorders (dystonia-Parkinsonism plus stereotypy) and psychiatric disorders (agitated catatonia, coprolalia, and echo phenomena). Both patients suffered concurrent hyperkinetic and Parkinsonian features resulting in therapeutic challenges. Bradykinetic features responded to dopamine replacement therapy and both patients also had adverse affects to dopamine antagonists (oculogyric crises plus neuroleptic malignant syndrome). Investigation was unremarkable other than the presence of CSF lymphocytosis and oligoclonal bands. Despite prolonged in-patient stays and intensive care management, both patients have made complete recoveries. We believe these cases support the hypothesis that this syndrome is an inflammatory encephalitis that specifically effects dopamine neurotransmission. © 2007 Movement Disorder Society [source]
