Association of prone position with sudden unexpected death in epilepsy.

Objective: To examine the association between prone position and sudden unexpected death in epilepsy (SUDEP).

Methods: We conducted a systematic review and meta-analysis based on a literature search from databases PubMed, Web of Science, and Scopus, using keywords "SUDEP" or "sudden unexpected death in epilepsy" or "sudden unexplained death syndromes in epilepsy." Twenty-five publications met the inclusion and exclusion criteria and were enrolled in this study.

Paraneoplastic nerve hyperexcitability.

Objectives: To provide an overview of paraneoplastic nerve hyperexcitability syndromes.

Methods: An extensive review of the literature on nerve hyperexcitability was performed. Particular attention was paid to Isaacs' syndrome and Morvan's syndrome, as well as their relationship to neoplasia.

Periictal autonomic dysfunction and generalized postictal EEG suppression in convulsive seizures arising from sleep and wakefulness.

Sleep appears to be an independent risk factor of sudden unexpected death in epilepsy (SUDEP). We retrospectively determined the periictal electrophysiological characteristics of nocturnal and diurnal generalized convulsive seizures (GCSs) in 109 patients. Our data showed that preictal heart rate (HR) was significantly lower in 46 patients with nocturnal GCSs than in 63 patients with diurnal GCSs (p=0.

Apoptosis: understanding the new molecular pathway.

Advances in science have increased the knowledge of how cells die in the body (apoptosis). A basic understanding of this process can improve nurses' ability to review new scientific literature and enable them to provide safer bedside care.
