Universal Level Designations for Hospitalized Pediatric Patients in Evacuation.

Children comprise approximately 22% of the population in the United States.1 In a widespread disaster such as a hurricane, pandemic, wildfire or major earthquake, children are at least proportionately affected to their share of the population, if not more so. They also have unique vulnerabilities including physical, mental, and developmental differences from adults, which make them more prone to adverse health effects of disasters.2-4 There are about 5000 pediatric critical care beds and 23 000 neonatal intensive care beds out of 900 000 total hospital beds in the United States.5 While no mechanism exists to consistently track pediatric acute care beds nationally (especially in real time), a previous study6 showed a 7% decline in pediatric medical-surgical beds between 2002 and 2011. This study also estimated there are about 30 000 acute care pediatric beds nationally. Finding appropriate hospital resources for the provision of care for pediatric disaster victims is an important concern for those charged with triaging patients in a major event.

Botulinum toxin for painful spasms from focal seizures: theoretical considerations and case report.

INTRODUCTION: Botulinum toxin (BTX) has been used to treat muscle overactivity and can reduce pain from muscle spasm. There are no previous reports to our knowledge of using BTX to treat the pain from intractable focal motor seizures. CASE REPORT: We present a case of chronic, focal, muscle pain, and spasm secondary to intractable focal motor seizures treated with BTX. The patient experienced significant relief in muscle pain despite continued seizures. CONCLUSIONS: On the basis of the case presented, BTX may have a limited role in the treatment of pain from muscle spasm in intractable focal seizures. Further study is necessary to see if this use of BTX is generally applicable.

Use of modafinil in patients with epilepsy.

Fatigue and excessive daytime sleepiness are common symptoms in patients with neurological injury. Modafinil has been shown to ameliorate these symptoms, but its use in patients with seizures has been limited because of safety concerns. Using a large centralized clinical registry, we performed a retrospective chart review of patients with a diagnosis of epilepsy who were given modafinil over a 10-year period. A total of 205 patients were analyzed. There were 91 patients who had seizures while taking modafinil; there was no relationship between modafinil dosage and whether the patient had seizures. There were 6 patients in whom modafinil was discontinued because of concern for seizure exacerbation, and 4 patients had de novo seizures after starting modafinil. In 29 patients with epilepsy only, no major seizure exacerbation was seen. Modafinil is potentially safe in patients with epilepsy, but further prospective studies are needed to fully determine its safety and efficacy.

Hippocampal and neocortical gamma oscillations predict memory formation in humans.

Functional magnetic resonance imaging (fMRI) of the human brain has shown that the hippocampus and the left temporal and frontal cortices play a key role in the formation of new verbal memories. We recorded electrical activity from 2349 surgically implanted intracranial electrodes in epilepsy patients while they studied and later recalled lists of common words. Using these recordings, we demonstrate that gamma oscillations (44-64 Hz) in the hippocampus and the left temporal and frontal cortices predict successful encoding of new verbal memories. This increase in gamma oscillations was not seen in other frequency bands, whose activity generally decreased during successful memory formation. These findings identify a role for gamma oscillations in verbal memory formation with the hippocampus and the left temporal and frontal cortices, the same regions implicated using noninvasive fMRI recording methods.
