Source localization of epileptiform discharges in childhood absence epilepsy using a distributed source model: a standardized, low-resolution, brain electromagnetic tomography (sLORETA) study.

Localizing the source of epileptiform discharges in generalized epilepsy has been controversial for the past few decades. Recent neuroimaging studies have shown that epileptiform discharges in generalized epilepsy can be localized to a particular region. Childhood absence epilepsy (CAE) is the most common generalized epilepsy in childhood and is considered the prototype of idiopathic generalized epilepsy (IGE).

Changes in background electroencephalographic activity in benign childhood epilepsy with centrotemporal spikes after oxcarbazepine treatment: a standardized low-resolution brain electromagnetic tomography (sLORETA) study.

Background: Several neuroimaging studies have reported neurophysiological alterations in patients with benign childhood epilepsy with centrotemporal spikes (BCECTS). However, reported outcomes have been inconsistent, and the progression of these changes in the brain remains unresolved. Moreover, background electroencephalography (EEG) in cases of BCECTS has not been performed often.

Comparative analysis of background EEG activity in childhood absence epilepsy during valproate treatment: a standardized, low-resolution, brain electromagnetic tomography (sLORETA) study.

Valproate (VPA) is an antiepileptic drug (AED) used for initial monotherapy in treating childhood absence epilepsy (CAE). EEG might be an alternative approach to explore the effects of AEDs on the central nervous system. We performed a comparative analysis of background EEG activity during VPA treatment by using standardized, low-resolution, brain electromagnetic tomography (sLORETA) to explore the effect of VPA in patients with CAE.

Distributed source localization of interictal spikes in benign childhood epilepsy with centrotemporal spikes: A standardized low-resolution brain electromagnetic tomography (sLORETA) study.

Benign childhood epilepsy with centrotemporal spikes (BCECTS), also known as Rolandic epilepsy, is the most common benign childhood epilepsy. Centrotemporal spikes are characteristic findings on electroencephalography (EEG). Though the condition is considered benign, many studies have reported some degree of neuropsychological impairment in individuals with BCECTS.

Neurocognitive outcome in survivors of childhood acute lymphoblastic leukemia: experience at a tertiary care hospital in Korea.

This study was conducted to investigate long-term neurocognitive outcomes and to determine associated risk factors in a cohort of Korean survivors of childhood acute lymphoblastic leukemia (ALL). Forty-two survivors of ALL were compared with 42 healthy controls on measures of a neurocognitive test battery. We analysed potential risk factors (cranial irradiation, sex, age at diagnosis, elapsed time from diagnosis, and ALL risk group) on neurocognitive outcomes.

Articulation error of children with adenoid hypertrophy.

Purpose: Adenoid hypertrophy is a physical alteration that may affect speech, and a speech disorder can have other negative effects on a child's life. Airway obstruction leads to constricted oral breathing and causes postural alterations of several oro-facial structures, including the mouth, tongue, and hyoid bone. The postural modifications may affect several aspects of speech production.

Altered DNA copy number in patients with different seizure disorder type: by array-CGH.

Epilepsy is one of the most common but genetically complex neurological disorders in children. Previous studies have showed that chromosomal abnormalities confer susceptibility to epilepsy. To identify new chromosomal abnormalities associated with epilepsy, DNA samples from patients with idiopathic generalized epilepsy (IGE), partial epilepsy (PE), and febrile seizures (FS) were analyzed using array comparative genome hybridization technique (array-CGH).

Aggressive systemic mastocytosis after germ cell tumor of the ovary: C-KIT mutation documentation in both disease states.

We report a case of aggressive systemic mastocytosis in a 3-year-old girl, who had undergone treatment for ovarian germ cell tumor during the previous 8 months. On diagnosis of systemic mastocytosis, she was treated with interferon-alpha and steroids. She showed tolerable side effects of interferon-alpha infusion, but died of multiple organ failure after 2 months of treatment.

Monokine levels in cancer and infection.

The levels of monocyte intracellular monokines (TNFalpha, MIP, and MIG) in patients with cancer or bacterial infection were studied by multiparameter flow cytometry and comparative fluorescence analysis. TNFalpha, MIP, and MIG levels in peripheral blood of patients with cancer or bacterial infection were higher than in normal controls (p < 0.005).

Melatonin attenuates kainic acid-induced hippocampal neurodegeneration and oxidative stress through microglial inhibition.

The antioxidant and anti-inflammatory effects of melatonin on kainic acid (KA)-induced neurodegeneration in the hippocampus were evaluated in vivo. It has been suggested that the pineal secretory product, melatonin, protects neurons in vitro from excitotoxicity mediated by kainate-sensitive glutamate receptors, and from oxidative stress-induced DNA damage and apoptosis. In this study, we injected 10 mg/kg kainate intraperitoneally (i.
