Encephalitis, a brain inflammation leading to severe illness and often death, is caused by >100 pathogens. To assess the incidence and trends of encephalitis in Ontario, Canada, we obtained data on 6,463 Ontario encephalitis hospitalizations from the hospital Discharge Abstract Database for April 2002-December 2013 and analyzed these data using multiple negative binomial regression. The estimat...

Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis is a form of autoimmune encephalitis associated with antibodies against the NR1 subunits of NMDARs. Although new-onset acute prominent psychotic syndromes in patients with NMDAR encephalitis have been well documented, there is a lack of case studies on differential diagnosis and treatment of anti-NMDAR encephalitis after a long-term diagno...

BACKGROUND Seizures are common in encephalitis but there is paucity of comprehensive studies evaluating predictors of seizures. AIM To evaluate the frequency and predictors of seizures in encephalitis patients and its effect on outcome. METHODS In a prospective hospital based study, the patients with encephalitis were evaluated clinically and presence of seizure, its type and duration were ...

Herpes simplex virus (HSV) encephalitis is a potentially devastating disease, with significant rates of mortality and co-morbidities. Although the prognosis for people with HSV encephalitis can be improved by prompt treatment with aciclovir, there are often delays involved in the diagnosis and treatment of the disease. In response, National Clinical Guidelines have been produced for the UK whic...

INTRODUCTION The objective of this study was to determine the incidence of herpes simplex encephalitis (HSE), known as the most common, potentially mortal, and treatable cause of sporadic encephalitis, in a sample Turkish population. METHODS The demographic, clinical, laboratory, imaging, electrophysiology, and polymerase chain reaction (PCR) DNA results of patients examined with a pre-diagno...

A presumptive case of Murray Valley Encephalitis (MVE) acquired in Alice Springs in March 1997 is reported. The patient subsequently died in Mackay. The diagnosis of Murray Valley Encephalitis was supported by the detection of flavivirus IgM in cerebrospinal fluid. Low titres of IgM specific to Murray Valley Encephalitis and Alfuy were detected in a single serum sample. The patient's travel mov...

While systemic viral infections are exceptionally common, symptomatic viral infections of the brain parenchyma itself are very rare, but a serious neurologic condition. It is estimated that viral encephalitis occurs at a rate of 1.4 cases per 100.000 inhabitants. Geography is a major determinant of encephalitis caused by vector-borne pathogens. A diagnosis of viral encephalitis could be a chall...

IntroductionAIDS patients are more susceptible to opportunistic diseases, such as toxoplasma encephalitis, because of weakened immune systems. Toxoplasma encephalitis manifests a severe neurological crisis in HIV patients. The standard initial treatments sulfadiazine and pyrimethamine. This case presents an patient treated with alternative regimen for encephalitis.Case descriptionA young Acehne...

Background: Sodium valproate (VPA), an anticonvalsant drug, has been reported to stimulate viral replication.  A combination therapy with VPA and acyclovir (ACV) is used for the treatment of herpesvirus encephalitis, the commonest sporadic encephalitis of viral origin. Objective: To determine a possible interaction between VPA and ACV leading to a modification of antiviral activity of ACV. Meth...

PURPOSE Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) may be used to establish a diagnosis of encephalitis, yet prior descriptions are mainly limited to small case reports. We explore the role of FDG-PET in the diagnostic evaluation of encephalitis. METHODS Brain FDG-PET was acquired in a consecutive case series of 10 cases of suspected encephalitis over a 5-year-perio...
