Health-related behaviors during adolescence have lifelong impacts. However, there are unclear areas regarding the associations between health-related quality of life and demographic characteristics, as well as physical and psychosocial indicators. The aim of this study was to examine the associations between quality of life and body weight, sleep outcome, social support by age, and cohabitants, given that income, self-esteem, lifestyle, emotional, social and behavioral problems were taken into account among adolescents in East and Southeast Asia.

Objectives: High-frequency oscillations (HFOs) on intracranial electroencephalography (EEG) recordings have been reported to be useful to identify the epileptogenic zone in intractable epilepsy. We investigated whether the ictal HFOs on scalp EEG seen during spasms contributed to identification of the epileptogenic zone in symptomatic West syndrome (S-WS).

Methods: In S-WS, ictal scalp EEGs were recorded during a series of spasms.

It has been hypothesized that early seizure control may prevent children with intractable epileptic spasms (ES) from developmental regression and may contribute to better developmental outcome. The effectiveness of surgery for ES has been reported. We investigated long-term post-operative outcomes of seizure control and development in patients with symptomatic West syndrome (S-WS) who underwent epilepsy surgery.

Glucose transporter 1 deficiency syndrome (Glut1-DS) is a congenital metabolic disorder characterized by refractory seizures with early infantile onset, developmental delay, movement disorders and acquired microcephaly. Glut1-DS is caused by heterozygous abnormalities of the SLC2A1 (Glut1) gene, whose product acts to transport glucose into the brain across the blood-brain barrier. We analyzed the SLC2A1 gene in 12 Japanese Glut1-DS patients who were diagnosed by characteristic clinical symptoms and hypoglycorrhachia as follows: all patients had infantile-onset seizures and mild to severe developmental delay, and ataxia was detected in 11 patients.

Adrenocorticotropic hormone (ACTH) has been the first-line drug for the treatment of West syndrome, although the therapy has various adverse effects. ACTH depresses resistance to a variety of bacterial, viral, protozoal, and fungal agents. The timing of the various vaccinations is delayed after ACTH therapy in Japan, because the immune system is believed to be affected for approximately 6 months.

The 1p36 deletion syndrome is caused by submicroscopic deletion in the subtelomeric region of chromosome 1. Epilepsy is one of the most important features of the syndrome, in addition to the characteristic facial appearance, cardiac anomaly, dysphagia, deafness, mental retardation and growth delay. We identified three patients with this syndrome and assessed the features of complicated epilepsy.
