Comparative Study
Second-line status epilepticus treatment: comparison of phenytoin, valproate, and levetiracetam.
Phenytoin (PHT), valproic acid (VPA), or levetiracetam (LEV) are commonly used as second-line treatment of status epilepticus (SE), but comparative studies are not available. ⋯ Even without significant differences on outcome at discharge, LEV seems less efficient than VPA to control SE after benzodiazepines. A prospective comparative trial is needed to address this potentially concerning finding.

Long-term medical management of epileptic drop attacks is usually unsatisfactory and more effective antiepileptic drug (AED) regimens are needed. The present study aimed at providing proof of concept that previously refractory epileptic drop attacks could be significantly and safely controlled by the specific combination of valproate, lamotrigine, and a benzodiazepine. ⋯ This open label study suggests that the combination of valproate, lamotrigine, and a benzodiazepine can markedly reduce the frequency of epileptic drop attacks in patients with generalized or multifocal epilepsies. Careful clinical monitoring for early signs of SJS is needed.

To determine if switching from select branded to generic equivalent antiepileptic drugs (AEDs) in patients with epilepsy is associated with adverse outcomes. ⋯ Brand to generic switching of phenytoin was not associated with more clinical events but was associated with increased index drug discontinuations, dose changes, or therapy augmentations. Lamotrigine or divalproex brand to generic switching was not associated with increased incidence of events or utilization changes compared with patients remaining on the branded product. Changes in AED utilization may be more sensitive than ED visits and hospitalizations for detecting adverse outcomes.

Comparative Study
EEG and video-EEG seizure monitoring has limited utility in patients with hypothalamic hamartoma and epilepsy.
Hypothalamic hamartomas (HHs) are a malformation of the ventral hypothalamus and tuber cinereum, associated with gelastic seizures and epilepsy. We sought to determine the spectrum of electroencephalography (EEG) abnormalities in a large cohort of HH patients. ⋯ EEG features in HH patients are diverse. The majority of gelastic seizures fail to demonstrate change in the EEG. The lack of EEG changes with many clinical seizures, and the false localization seen in those events with an ictal change suggest the utility of EEG is limited in the evaluation of these patients.

To pool data from four published case-control studies of sudden unexpected death in epilepsy (SUDEP) with live controls, to increase the power to determine risk factors. ⋯ This analysis refines the identification of people with epilepsy that are at particular risk of SUDEP. The emerging profile indicates that people with early onset refractory symptomatic epilepsy with frequent GTCS and antiepileptic drug (AED) polytherapy are at higher risk. The results suggest that reduction of the number of GTCS is a priority, of more importance than reducing the number of AEDs. The role of AEDs and other treatment should be analyzed further in future studies.
