Randomized Controlled Trial Multicenter Study
Intramuscular midazolam versus intravenous lorazepam for the prehospital treatment of status epilepticus in the pediatric population.
To examine the effectiveness of intramuscular (IM) midazolam versus intravenous (IV) lorazepam for the treatment of pediatric patients with status epilepticus (SE) in the prehospital care setting. ⋯ IM midazolam can be rapidly administered and appears to be safe and effective for the management of children with SE treated in the prehospital setting. The results must be interpreted in the context of the secondary analysis design and sample size of the study.

To develop a better understanding of mechanisms of seizures and long-term epileptogenesis using neurocysticercosis. ⋯ Naturally occurring brain infections with neurocysticercosis offer a unique opportunity to develop treatments for one of the world's most common causes of epilepsy and for the development of more general antiepileptogenic treatments. Key advantages stem from the time course in which an acute seizure heralds a start of the epileptogenic process, and radiographic changes of calcification and perilesional edema provide biomarkers of a chronic epileptic state.

There is increasing evidence that epileptic activity involves widespread brain networks rather than single sources and that these networks contribute to interictal brain dysfunction. We investigated the fast-varying behavior of epileptic networks during interictal spikes in right and left temporal lobe epilepsy (RTLE and LTLE) at a whole-brain scale using directed connectivity. ⋯ The different patterns of time-varying connectivity in LTLE and RTLE suggest that they are not symmetrical entities, in line with our neuropsychological results. The highest outflow region was concordant with invasive validation of the epileptogenic zone. This enhanced characterization of dynamic connectivity patterns could better explain cognitive deficits and help the management of epilepsy surgery candidates.

The 6 Hz model of focal seizures has been increasingly used to identify anticonvulsant compounds with potential activity against therapy-resistant epilepsy, but the protective response to anticonvulsants in this model could be dependent on experimental conditions and selection of mouse strains. ⋯ Collectively these observations clearly indicate that treatment resistance of 6 Hz seizures should be interpreted with strain and experimental conditions in mind. Furthermore, it is important to note that strain differences, much like human genetic differences, may explain why some mice and patients respond to a given treatment and others do not.
