Objective: This study aimed to elucidate the electro-clinical characteristics of epilepsy and immunological markers in patients with epilepsy after infl uenza-associated encephalopathy/encephalitis (IAE). Methods: Eighteen patients with epilepsy after IAE (8 males, 10 females; mean age of onset 6.4±6.4 years) were studied. Antibodies to glutamate receptor (GluR) ε2 (NR2B) were examined by immunoblot and ELISA. Cytokines were measured by BioPlex. Results: Mean interval between IAE and epilepsy onset was 63.2 ± 95.0 days (mean ± SD). In 16 of 18 patients, complex partial seizures were observed. Most complex partial seizures were of short durations and showed few lateralizing signs. Interictal discharges were seen in the frontal area in 7 of 14 patients. Ictal EEG showed rapid propagation to bilateral hemispheres. Patients with higher cerebrospinal fl uid levels of anti-GluRε2 antibodies, higher cerebrospinal fl uid levels of IL-1β, soluble tumor necrosis factor receptor 1 and IFN-γ during chronic stage, had higher frequency of epileptic seizures. Conclusion: This study indicates that the frontal lobes are susceptible to rapid epileptogenesis after IAE, and that epileptic partial seizures after IAE had characteristics resembling generalized seizures. Presence of anti-GluRε2 antibodies and elevated IL-1β, TNFα, and IFN-γ in cerebrospinal fl uid may be associated with intractability of epileptic seizures.

Purpose : This study was undertaken to examine the relationship between pedometer counts and food intake in Japanese elderly people.Methods : One-hundred-eighty healthy, community-dwelling elderly people were divided into three groups according to age. The number of steps taken by each subject was recorded with a pedometer over a 30-day period in August. The dietary and nutritional intakes were estimated using a food frequency questionnaire.Results : There was no significant difference in the pedometer counts between men and women. The number of steps significantly decreased with age (p<0.01). The intake of energy, protein and carbohydrate were significantly higher in men than in women (p<0.05), and they were nearly the same among the three aged groups. The calcium and vitamin C intakes after adjusting for sex and age increased with the number of daily steps, except for the intakes of energy, protein and carbohydrates.Conclusion : A higher number of daily steps was found to be associated with the calcium and vitamin C intakes.
