Comparative Study
Epilepsy in Rett syndrome---the experience of a National Rett Center.
Rett syndrome (RTT), an X-linked, dominant neurodevelopmental disorder caused by mutations in the methyl-CpG-binding protein 2 (MECP2) gene, presents with acquired microcephaly, autistic regression, hand usage loss, and stereotypies. Epilepsy is frequent and has been reported to correlate with mutation type, general disease severity, and BDNF polymorphism. Our purpose was a comprehensive description of epilepsy features and course in RTT. ⋯ Epilepsy appears earlier than described previously, frequently during the regression stage. Early age of onset predicts a more severe course of seizures. ESES is common among those with early onset epilepsy. BDNF polymorphism was the only genetic correlate with seizure onset, whereas MECP2 mutation type and location did not influence epilepsy.

Meta Analysis Comparative Study
Long-term add-on pregabalin treatment in patients with partial-onset epilepsy: pooled analysis of open-label clinical trials.
To evaluate the safety, tolerability, and efficacy of long-term pregabalin as add-on therapy for patients with poorly controlled partial seizures. ⋯ Adjunctive pregabalin was effective, generally well tolerated, and safe in the long-term treatment of partial seizures, and provided clinically meaningful seizure reduction and freedom without evidence of tolerance over 2 years of follow-up.

The incidence of constipation as an adverse effect of pregabalin has previously been reported as low, with all cases described as either mild or moderate. From the experience of a tertiary referral epilepsy hospital center, we report several cases of severe and disabling constipation after initiating pregabalin, and resolving only on drug withdrawal. ⋯ The severity of symptoms was dose dependent. Pregabalin can cause marked constipation in some patients, and can lead to multiple unnecessary investigations and procedures if the clinician is not aware of this entirely reversible side effect.

Randomized Controlled Trial Multicenter Study Comparative Study
Lacosamide as adjunctive therapy for partial-onset seizures: a randomized controlled trial.
To evaluate the efficacy and safety of lacosamide (400 and 600 mg/day) as adjunctive treatment in patients with uncontrolled partial-onset seizures taking one to three concomitant antiepileptic drugs (AEDs). ⋯ Adjunctive treatment with lacosamide 400 and 600 mg/day reduced seizure frequency for patients with uncontrolled partial-onset seizures. Lacosamide 400 mg/day provided a good balance of efficacy and tolerability; lacosamide 600 mg/day may provide additional benefit for some patients as suggested by secondary efficacy analyses, including response in patients with secondarily generalized tonic-clonic seizures.

Multicenter Study Comparative Study Clinical Trial
Intravenous lacosamide as short-term replacement for oral lacosamide in partial-onset seizures.
Lacosamide is a new antiepileptic drug effective for adjunctive treatment of partial-onset seizures. We evaluated the safety and tolerability of an intravenous (i.v.) formulation of lacosamide (200-800 mg/day) infused over 10, 15, and 30 min as short-term replacement for oral lacosamide in patients with partial-onset seizures. ⋯ This comprehensive evaluation supports the safety of an intravenous lacosamide infusion duration as short as 15 min for short-term (2-5 days) replacement for patients temporarily unable to take oral lacosamide.
