Antiepileptic drugs (AEDs) can adversely affect cognitive function by suppressing neuronal excitability or enhancing inhibitory neurotransmission.The main effects of AEDs are impaired attention, vigilance, and psychomotor speed, but secondary manifest on other functions.Although the long-term use obviously elicit dysfunction in epilepsy patients, their over short periods up to a year inconclusive due methodological problems.In general, cognition worse for older (e.g., phenobarbital) than...

In addition to aberrant features in the speech, children with Autism Spectrum Disorder (ASD) may present unusual responses sensory stimuli, especially auditory stimuli. We investigated ability of ASD by using Auditory Brainstem Responses (ABR) as they can directly judge both hearing status and integrity brainstem pathways. One hundred twenty-one (71: ASD; M 58/ F 13, mean age; 41.8 months, 50: control group; 41/ 9, 38 months) were included study. As compared values group, latency wave V,...

To prospectively evaluate the neuropsychological effect of levetiracetam (LVT) in comparison with carbamazepine (CBZ) and its efficacy tolerability as a monotherapy children focal epilepsy.A total 121 out 135 screened (4-16 years) were randomly assigned to LVT or CBZ groups multicenter, parallel-group, open-label trial. The study's primary endpoints defined end 52 weeks treatment, followed by analysis changes observed series follow-up neurocognitive, behavioral, emotional function tests...

In this paper, an efficient digit-serial systolic array is proposed for multiplication in finite field GF(2/sup m/) using the standard basis representation. From least significant bit first algorithm, we obtain a new dependence graph and design multiplier. If input data come continuously, can produce results at rate of one every /spl lceil/m/L/spl rceil/ clock cycles, where L selected digit size. Analysis shows that computational delay time architecture significantly less than previously...

The risk of suicide or attempts is reported higher in people with epilepsy (PWE) than the general population. Although epileptic, psychiatric, and psychosocial factors are known for attempt, no studies have evaluated predictors severity suicidal ideation-which a warning sign attempts-in PWE. Therefore, we measured ideation its factors.Consecutive PWE who were medicated antiepileptic drugs (AEDs) attended clinic included study. subjects completed self-reported questionnaires, which Beck...

Recently, adipose tissue-derived stem cells (ASCs) were emerged as an alternative, abundant, and easily accessible source of cell therapy. Previous studies revealed losartan (an angiotensin II type I receptor blocker) treatment promoted the healing skeletal muscle by attenuation TGF-β signaling pathway, which inhibits differentiation. Therefore, we hypothesized that a combined therapy using ASCs might dramatically improve remodeling after injury. To determine effect with ASC transplantation,...

The US Food and Drug Administration approval for perampanel has only recently been expanded to patients as young 4 years, so there have few real-life studies of the effects in pediatric patients. aim this study was determine long-term efficacy, factors affecting treatment response, tolerability an add-on therapy aged years or older with epilepsy.This multicenter retrospective observational collected data from epilepsy centers four Korean national universities. Changes seizure frequency...

This study was conducted to investigate the etiology, clinical characteristics and prognosis of acute necrotizing encephalopathy (ANE) in Korean children. Six children (1 yr 7 yr) patients with ANE were enrolled. They diagnosed by radiological their data retrospectively analyzed. In a search clinically plausible causes, brain MRI all patients, mitochondrial DNA studies for encephalomyopathy, lactic acidosis, strokelike episodes (MELAS) myoclonus epilepsy ragged red fibers (MERRF) four...

ABSTRACT Objectives: To assess and compare the long‐term therapeutic response to lamivudine compared with interferon‐α (IFN‐α) in children chronic hepatitis B. Methods: A total of 40 (27 male; age, 1.3–18 y, mean, 7.7 y) B who received for at least 12 months were followed a mean period 39 (24–76) months. Their treatment efficacy was historically that 19 (14 2.1–17 y; 10 had been treated IFN‐α (24–104) Therapeutic responses 2 y after initiation either methods. Results: Two years treatment,...
