Background: Acute Encephalitis Syndrome (AES) is defined as a person of any age, at any time of year with the acute onset of fever and a change in mental status (including symptoms such as confusion, disorientation, coma, or inability to talk) and/or new onset of seizures (excluding simple febrile seizures). Viruses have been mainly attributed to be the cause of AES in India although other etiologies such as bacteria, fungus, parasites, spirochetes, leptospira, toxoplasma, rickettsia, chemical, and toxins have also been reported over the past few years. The causative agent of AES varies with season and geographical location, owing to wide range of causative agents and the rapid neurological impairment due to pathogenesis, clinicians face the challenge of a small window period between diagnosis and treatment. The present study is dedicated to knowing the present epidemiological pattern of AES in Bihar aiming to help in diagnosis and treatment.Methods: This is a prospective study conducted in the department of pediatrics, Patna Medical College and Hospital, Patna from January 1st to December 31st, 2016, in this study all cases which presented with acute onset of fever and a change in mental status including symptoms such as confusion, disorientation, coma or inability to talk and/ or new onset of seizures excluding simple febrile seizures were included. Demographic, etiological analysis and outcome of cases of Acute Encephalitic Syndrome as well as Japanese encephalitis were done.Results: The total number of patient diagnosed clinically with AES were 186 of them 105 were male and 81 were female. Number of cases were highest in the age group of >5-10 years amounting to 37.7% followed by 26.4% in >2-5 years age group, marked male predominance was seen in the age group 5 -10 years. A minor female predominance was observed in the age group >10 years. In May number of cases were maximum 36 (19.4%) followed by April 32 (17.2%), number of cases of AES were least in the month of December followed by November (8). Maximum number of cases were from the district of Patna and its neighboring district amounting to 58.5% with Nalanda district alone comprises 24.3%. Etiological analysis reveals that 36.5% children admitted with the clinical diagnosis of AES, 36.5% were diagnosed with Acute bacterial meningoencephalitis and 22.04% were diagnosed with Japanese Encephalitis, 7.5% Tuberculous meningitis, 6.4% Cerebral malaria, 5.4% Herpes simplex encephalitis and 3.2% with acute encephalitis syndrome unknown.Conclusions: Acute Encephalitis Syndrome remains an important cause of prolonged hospital bed occupancy with a high rate of mortality. Although in JE positive cases mortality were less, but morbidity in form of various motor deficit and cognitive impairment increases the burden on the family and society. With the introduction of effective JE vaccine and with rigorous surveillance of AES cases and social initiative taken by the Government, we can hope a better scenario. More and more extensive studies are the need of hour to know more about the etiopathogenesis of AES, so that future strategies to bring down the mortality and morbidity due to this disease can be carried out.

Record Section

This is a hospital based retrospective study, which was done in Pediatric ward of Patan hospital. Study period was one and half year (from Srawan 2063 to 2064 poush).Data were taken from discharge book of Pediatric ward, from the record section of this hospital, and from JE surveillance office, WHO, Kathmandu. All children from 1 month to 14 years ,who were admitted in Pediatric ward with symptoms of Meningitis, Meningoencephalitis and Encephalitis were included in this study and patients more than 14 years of age and symptoms not suggestive of meningitis, meningoencephalitis or encephalitis were excluded from the study. Headache; vomiting and fever were the chief complaints of patients. Two patients died during study period. There were 16 patients with serologically confirmed Japanese encephalitis.

Objective: To determine the profile and outcome of children admitted with Acute Encephalitis Syndrome (AES) and to find out the prevalence of Japanese Encephalitis (JE) IgM antibodies positive cases among these patients with their case fatality rate (CFR). Materials and methods: Study consist of retrospective analysis of hospital records of children up to 15 years of age admitted with diagnosis of AES in pediatric wards of College of Medical Sciences-Teaching Hospital, Bharatpur from January 2007 to December 2008. Results: During two years, 61 patients of AES were admitted. Male and female patients were 33 and 28 respectively. Meningitis accounted for 29 and encephalitis for 32 patients. JE IgM seropositive cases contributed for 18% of all AES cases. Case fatality for JE was 16.6%. Conclusions: Japanese Encephalitis is endemic in catchment area of the hospital. JE has significant morbidity and mortality which can be prevented by immunization and mortality can be reduced if supportive interventions are provided in time. Key words: AES; JE; CFR.

Background and Objectives. Japanese encephalitis (JE) is the most important cause of acute and epidemic viral encephalitis. Every year sporadic JE cases are reported from the various districts of West Bengal, indicating its endemicity in this state. JE vaccination programme has been undertaken by the State Health Department of West Bengal. This study was aimed at seeing the present scenario of JE among acute encephalitis syndrome (AES) cases in West Bengal.Materials and Methods. Blood and/or CSF samples were referred from suspected AES cases to the referral virology laboratory of the Calcutta School of Tropical Medicine from different hospitals of Kolkata. IgM antibody capture ELISA was performed on the CSF and serum samples by JE virus MAC ELISA kit supplied by the National Institute of Virology, Pune.Results. The present study reveals that 22.76% and 5% of the AES cases were positive for JE IgM in 2011 and 2012, respectively. JE is mainly prevalent in children and adolescents below 20 years of age with no gender predilection. Although the percentages of JE positive cases were high in 2011, it sharply decreased thereafter possibly due to better awareness programs, due to mass vaccination, or simply due to natural epidemiological niche periodicity due to herd immunity.
