Comparative StudyHealth-related quality of life of children with epilepsy in Hong Kong: how does it compare with that of youth with epilepsy in Canada?
The primary aim of our study was to compare the health-related quality of life (HRQL) of children with epilepsy in Hong Kong with that of children with epilepsy in Canada, and to explore possible factors affecting these findings. A second interest was to determine agreement between proxy reports and self-ratings among children with epilepsy in Hong Kong, compare these with findings in Canada, and identify factors that influence the concordance. ⋯ Youth with epilepsy in Hong Kong and their parents reported poorer quality of life than children with epilepsy in Canada. Further studies are necessary to identify the determinants of HRQL in children with epilepsy in different cultures. Acceptable agreement between the two ratings suggests that proxy reports can be used when child self-reports cannot be obtained.

Comprehensive presurgical functional MRI language evaluation in adult patients with epilepsy.
Functional magnetic resonance imaging (fMRI) has the potential to replace the intracarotid amobarbital procedure (IAP) in presurgical evaluation of patients with epilepsy. In this study, we compared fMRI verb generation (VG) and semantic decision/tone decision (SDTD) tasks and the IAP in their ability to localize language functions in patients with epilepsy undergoing presurgical evaluation. We enrolled 50 healthy controls to establish normal language activation patterns for VG and SDTD tasks at 3 or 4 T, and to design language regions of interest (ROIs) that were later applied to 38 patients with epilepsy (28 of 38 also underwent the IAP). ⋯ In the general linear modeling, only the SDTD task significantly contributed to the determination of language lateralization in patients with epilepsy undergoing presurgical evaluation. Results indicate a moderate convergent validity between both fMRI language tasks and between IAP and fMRI tasks. The results of this study indicate that either of these fMRI tasks can be used for language lateralization in patients with epilepsy undergoing presurgical evaluation, but that the SDTD task is likely to provide more information regarding language lateralization than the VG task.

Case ReportsPregabalin-induced generalized myoclonic status epilepticus in patients with chronic pain.
Pregabalin is often used for the treatment of chronic pain syndromes. We here describe two patients with chronic pain and pregabalin-induced myoclonic status epilepticus. Patients treated with pregabalin who experience sudden behavioral changes or mycloni should be investigated for this possible side effect, and pregabalin should be reduced or discontinued if myocloni or status epilepticus occurs.

Parents of children with enduring epilepsy: predictors of parenting stress and parenting.
The goals of the work described here were (1) to predict parenting stress and parenting from stressors, resources, and parental coping behaviors in parents of children with epilepsy, and (2) to determine whether parenting stress mediates the effects of these predictors on parenting. ⋯ In the context of pediatric epilepsy, parenting stress mediates both disruptive and resilient family factors for their effects on parenting. Parents of children with epilepsy may benefit from parent training programs that, to reduce parenting stress, address epilepsy education, the management of difficult child temperament, building social support networks, and the modification of inadequate parental coping behaviors.

Isobolographic analysis of interactions between remacemide and conventional antiepileptic drugs in the mouse model of maximal electroshock.
Using the mouse maximal electroshock-induced seizure model, indicative of tonic-clonic seizures in humans, the present study was aimed at characterizing the interaction between remacemide and valproate, carbamazepine, phenytoin, and phenobarbital. Isobolographic analysis indicated additive interactions between remacemide and valproate, carbamazepine, and phenytoin (for all fixed ratios of tested drugs: 1:3, 1:1, and 3:1). Additivity was also observed between remacemide and phenobarbital applied in proportions of 1:1 and 3:1. ⋯ In contrast, phenobarbital co-administration was associated with decreases in brain remacemide (27%) and desglycinyl-remacemide (9%) concentrations, whereas only remacemide concentrations (increased by 131%) were affected by carbamazepine co-administration. In conclusion, significant and desirable pharmacodynamic interactions were observed between remacemide and valproate, carbamazepine, phenytoin, and phenobarbital. However, the concurrent pharmacokinetic interactions associated with remacemide complicate these observations and do not make remacemide a good candidate for adjunctive treatment of epilepsy.
