Case Reports
Intravenous lacosamide--an effective add-on treatment of refractory status epilepticus.
Status epilepticus (SE) is a frequent neurological emergency requiring immediate treatment. Therapy usually requires intravenous anticonvulsive medication. Lacosamide is a novel anticonvulsant drug that is available as infusion solution. ⋯ In all cases, SE was terminated within 24 h after Lacosamide. There were no serious side effects or adverse events attributable to Lacosamide i.v. Our data suggest that Lacosamide might be an effective add-on treatment, if standard drugs fail or are unsuitable.

Basic and clinical neuroscience research findings suggest that cortical spreading depression (CSD) and epileptic foci may facilitate each other; furthermore, the threshold required for the onset of CSD has been suggested to be lower than that required for an epileptic focus. These data may explain the prevalence of epilepsy in migraine populations (ranging from 1% to 17%) and the frequency of migraine in epileptic populations (ranging from 8.4% to 20%). There is currently a considerable amount of confusion regarding this topic in both headache and epilepsy classifications (ICHD-II and ILAE). ⋯ However, neither "migralepsy" nor "hemicrania epileptica" are terms used in the current ILAE classification. On the basis of data reported in the literature and our recent findings, we suggest that the terms "migraine-triggered seizure" and "migralepsy" be deleted until unequivocal evidence of the existence of these conditions emerges. "Ictal epileptic headache" (IEH) should be used to classify those rare events in which headache represents the sole ictal epileptic manifestation. On the other hand, the term "hemicrania epileptica" should be maintained in the ICHD-II and introduced into the ILAE, and be used to classify all cases in which an "ictal epileptic headache" "coexists" and is associated synchronously or sequentially with other ictal sensory-motor events.

Case Reports
Successful treatment of refractory simple motor status epilepticus with lacosamide and levetiracetam.
Lacosamide has been reported to have been successfully used for non-convulsive status epilepticus after benzodiazepine failure, and convulsive status epilepticus after benzodiazepine and levetiracetam failure. We report a case of simple motor status epilepticus refractory to benzodiazepines and multiple anti-epileptic medications (AEDs) over 4 days. The addition of lacosamide in combination with existing levetiracetam aborted the continuous seizure with maintenance of seizure freedom through the most recent follow-up at 4 weeks.

This study aimed to determine the etiology, treatment protocol and outcome of convulsive status epilepticus (SE) in children. An institutional treatment protocol using benzodiazepines (diazepam and midazolam) was assessed in a retrospective case study. The treatment protocol (Ege Pediatric Status Epilepticus Protocol or EPSEP) was developed based on an operational definition of pediatric SE according to the duration of seizure activity. ⋯ Midazolam bolus and infusions (up to 1.2 μg/kg/min) were used to treat 22 episodes of SE (9 refractory SE, 10 established SE and 3 initial SE). Complete arrest of convulsive SE was achieved in 21 of 22 (95%) episodes with midazolam infusion. We concluded that the combined use of benzodiazepines (diazepam+midazolam) was safe and effective in the treatment of convulsive SE in children.

Epilepsy is common in people with intellectual disabilities. Epilepsy can be difficult to diagnose and may be misdiagnosed in around 25% of cases. A systematic review was conducted to explore: (i) How common the misdiagnosis of epilepsy is amongst people with intellectual disabilities. (ii) Reasons for misdiagnosis of epilepsy. (iii) Implications of misdiagnosis. (iv) Improving diagnosis. ⋯ Those working in epilepsy and intellectual disability services and families must be made more aware of the possibility of misdiagnosis. Future research is needed about the misdiagnosis of epilepsy amongst people with intellectual disabilities and carer knowledge.
