METHODS: We prospectively evaluated children with serologically confirmed Japanese encephalitis over an 8.3-year period. The patients were assessed and their outcomes were graded with a functional outcome score at hospital discharge and at follow-up appointments. We examined how patient outcome at hospital discharge compared with that at long-term follow-up visits, when changes in outcome occurred, and the prognostic indicators of the eventual outcome.
RESULTS: One hundred and eighteen patients were recruited into the study, and 10 (8%) died during the acute phase of illness. At hospital discharge, 44 (41%) of the 108 patients who survived had apparent full recovery; 3 (3%) had mild, 28 (26%) had moderate, and 33 (31%) had severe neurological sequelae. Eighty six of the 108 patients were followed up for a median duration of 52.9 months (range, 0.9-114.9 months). During follow-up, 31 patients experienced improvement, but 15 patients experienced deterioration in their outcome grade. In most cases, assessment during the first 3-6 months after hospital discharge was predictive of the long-term outcome. More than one-half of the patients continued to experience neuropsychological sequelae and behavioral disorders. A combination of poor perfusion, Glasgow coma score < or =8, and > or =2 witnessed seizures predicted a poor long-term outcome with 65% sensitivity and 92% specificity.
CONCLUSIONS: Neurological assessment of Japanese encephalitis survivors at hospital discharge does not predict long-term outcome. Seizures and shock are treatable risk factors for a poor outcome at hospital discharge and at long-term follow-up visits.
AIMS: This study was performed to evaluate and compare the oxidative changes in patients with varying severity of HI in the early posttraumatic period using erythrocyte indicators.
SETTINGS AND DESIGN: Head injury patients were divided into two groups based on their Glasgow Coma Scale (GCS) scores recorded at admission to the hospital on the day of trauma itself. Accordingly, the study included 30 severe HI (SHI, GCS scores 8 or less) and 25 Mild HI (MHI, GCS scores more than 8) patients. Thirty age and sex-matched healthy individuals were included in this comparative study as controls.
MATERIALS AND METHODS: Blood samples were obtained from controls and HI patients (within 24 h of trauma onset). Erythrocyte oxidative changes were studied by estimating thiobarbituric acid reactive substances (TBARS), glutathione (GSH), superoxide dismutase (SOD) and glutathione reductase (GR).
RESULTS: Erythrocyte TBARS levels were significantly higher and GSH levels were significantly lower in SHI and MHI patients as compared to controls. The SOD activity was significantly increased only in SHI patients and remained unchanged in MHI patients as compared to controls. As compared to MHI patients, erythrocyte TBARS levels were significantly higher, GSH levels were significantly lower and SOD activity was markedly elevated in SHI patients. Erythrocyte GR activity did not show significant changes in both groups of patients as compared to controls.
CONCLUSION: Oxidative stress is evident in both SHI and MHI patients in the early posttraumatic period as reflected by their erythrocyte indicators, but the severity of oxidative stress has varied relatively with the severity of head injury. The present findings provide indications that early oxidative changes could influence the neurological recovery of HI patients.
