Benign neonatal sleep myoclonus: history and semiology.

Benign neonatal sleep myoclonus is a condition characterized by myoclonus occurring during sleep. Reported here are 18 cases of infants who had electroencephalographic monitoring, with myoclonic events recorded in 17 cases. In all cases, onset was within days to a few weeks of birth.

Possible precipitation of myoclonic seizures with oxcarbazepine.

Oxcarbazepine is an antiepileptic drug widely used to treat partial seizures in children and adults. We report two children who developed mycolonic seizures and had abnormal electroencephalograms when oxcarbazepine was introduced. Although it is possible that the emergence of myoclonic seizures and deterioration of the electroencephalograms were due to the natural course of the disorder, clinicians should be aware of the possible detrimental effects of oxcarbazepine in children with seizures.
