Purpose: To evaluate the frequency and causes of hyponatremia in acute encephalitis syndrome (AES) and its effect on outcome. Patients and Methods: Consecutive patients with AES were subjected to neurological evaluation including Glasgow Coma Scale, focal weakness, movement disorder, and reflex changes. The etiology of AES was based on blood and cerebrospinal fluid enzyme-linked immunosorbent assay and polymerase chain reaction. We have categorized patients into neurological or systemic AES. Hyponatremia was diagnosed if 2 consecutive serum sodium levels were below 135 mEq/L, 24 hours apart. Serum and urinary osmolality and electrolytes were measured on alternate days. Fluid intake, output, and body weight were measured daily. The hyponatremia was categorized into syndrome of inappropriate secretion of antidiuretic hormone (SIADH), cerebral salt wasting (CSW), or miscellaneous group. Outcome at 1 month was assessed by modified Rankin scale. Results: Of 79 patients, 34 had neurologic AES and 45 had systemic AES; 22 (27.8%) patients had hyponatremia. The neurologic AES as compared to systemic AES was more commonly associated with hyponatremia (38.2% vs 20%, P = .07), need longer hospitalization (25.0 vs 12.5 days, P = .003), and longer time for sodium correction (13.3 vs 8.2 days, P = .05). The hyponatremia was due to CSW in 12 patients, SIADH in 2 patients, and indeterminate in 8 patients. Thirty-six patients had poor outcome (15 died) and 43 had good outcome which was not related to hyponatremia. Conclusion: Hyponatremia occurs in one-third of patients with AES, being commoner in neurologic AES, and CSW is the commonest cause.

Background: Acute Encephalitis Syndrome (AES) is a major public health issue in India. The common etiologies of AES in India are various infectious agents. There are seasonal and regional variations in etiologies making diagnosis and effective intervention often difficult. Our study represents the epidemiological data that will help in planning management in larger perspective.Methods: This is a six years prospective observational study conducted in the Department of Pediatrics, North Bengal Medical College Hospital, Darjeeling from January 1st, 2013 to December 31st, 2018. In this study all clinically diagnosed AES cases were included fulfilling inclusion and exclusion criterion.Results: 585 out of 39420 patients (1.48%) were diagnosed clinically as AES over six years. Male patients (372) contributing to 63.6% and female patients (213) 36.4% of the study. Majority cases (271) were seen in the age group of 1-5 years amounting to 46.3% with mean age 5.1±3.6 years. In July 2014 number of cases were maximum 59 (10%) followed by May 2013 20 (3.4%). Among the 585 AES cases, 263 (45%) were suspected for viral etiology (JE= 84, 14.3%). Total 457 cases (78.1%) were alive with insignificant to age and gender variance. Vaccination status revealed 11 among 15 JE deaths were unimmunized which is statistically significant (p < 0.05) by Chi-square test.Conclusions: The magnitude and etiologies of AES need to be explored and understood in various geographic regions and in different seasons to have a better insight for development of future policies to reduce the burden.

Introduction: The clinical features of Acute Encephalitis syndrome (AES) vary widely across the world and little documentation is available from North Bengal. Materials and methods: A cross –sectional observational study was conducted at the Department of Medicine of a teaching hospital in North Bengal. 104 AES cases were enrolled and clinically evaluated and investigated as per the study protocol. Results:JE (72%) was most common causative agent followed by HSV Encephalitis (11.5%), Scrub Typhus (9.6%) and Dengue Encephalitis (2.88%). Male cases were predominant than female in our study. Fever and altered sensorium were most common presentation followed by seizures (51.9%), headache (29.8%), vomiting (18.2%), and hemiplegia (4.8%). Neurological evaluation revealed 80% of the patients had neck stiffness followed by positive Babinski sign (45.19%) and hypertonia (35%). Conclusions: JE is the commonest cause of AES in North Bengal and seizures are the commonest neurological manifestation after altered sensorium.

Abstract Objective To estimate the level of myelin basic protein (MBP) and look for its validity in outcome prediction among mild-to-moderate head injury patients. Materials and Methods It was a prospective study done at the Department of Neurosurgery, Institute of Medical Sciences, Banaras Hindu University from Jan 2018 to July 2019. All patients who presented to us within 48 hours of injury with mild-to-moderate head injury with apparently normal CT brain were include in the study. The serum sample were collected on the day of admission and 48 hours later, and patients were treated with standard protocols and observed 6 months postdischarge. Results Of the 32 patients enrolled, we observed mean MBP level was higher for severity of brain damage, but not associated with age, mode of injury, and radiological diagnosis. Mean MBP levels were not statistically associated with Glasgow coma scale (GCS) score at admission but was correlated to outcome with p < 0.05, with sensitivity of 50% and specificity 72%, that is, patients with good outcome have lower mean MBP levels. Conclusion MBP as per our analysis can be used as a prognostic marker in patients with head injury. It is not the absolute value rather a trend showing rise in serum MBP levels, which carries a significant value in outcome prediction.
