Amplitude-integrated EEG use in neonatal abstinence syndrome: a pilot study.

Objective: Though central nervous system irritability is a well-established consequence of neonatal drug withdrawal, brain function in infants with neonatal abstinence syndrome (NAS) is not well understood. Amplitude-integrated electroencephalography (aEEG) is a bedside tool used for monitoring brain activity and seizures. We describe the prevalence of abnormal aEEG background patterns in infants with NAS.Methods: In this pilot, observational study primary outcomes were aEEG findings, Finnegan scores, and length of hospital stay in NAS patients. Subjects underwent an initial aEEG and a repeat study following pharmacologic treatment. Two independent reviewers analyzed aEEGs post discharge.Results: Six out of nine infants had abnormal aEEGs demonstrating lack of sleep-wake cycling (SWC) (50%), discontinuity (41.7%), and low voltage (8.3%). Seizures were not detected. NAS scores were lower for infants with continuous aEEGs versus those whose aEEGs were not continuous (5.83 versus 9.17; p = .054). Length of stay was 7.8 ± 4.4 days in infants with continuous aEEGs versus 26 ± 10.5 days in infants without continuous aEEGs (p = .003).Conclusions: Infants exposed to opioids in utero are at increased risk for discontinuity and abnormal SWC detectable on aEEG. Infants with abnormal aEEGs are more likely to have higher NAS scores, require pharmacologic treatment and have longer lengths of stay.

Status epilepticus treatment and outcome in children: what might the future hold?

Status epilepticus is a life-threatening emergency that requires urgent treatment. Over the past decade, numerous advances have been made in the management of status epilepticus. Clinical studies have now established the benefit of early, aggressive treatment of status epilepticus with benzodiazepines in both prehospital and hospital settings. Neuroscientific advances are revealing mechanisms of status epilepticus that could translate into targets for treating acute status epilepticus and even reducing epileptogenesis. This article discusses future trends in the diagnosis, neurobiology, and treatment of status epilepticus.

Neuromuscular hyperexcitability associated with acetylcholine receptor antibodies in a child.

This report describes the clinical and electrophysiological features of an 8-year-old boy with autoimmune neuromuscular hyperexcitability. He presented with features of lower extremity pain, stiffness, and rippling muscles. The diagnosis was made by electromyography and supported by the presence of an antibody directed against nicotinic acetylcholine receptors. His symptoms responded to immunomodulatory treatment with intravenous immunoglobulin. Response to immunomodulatory therapy has not previously been described in the pediatric population with autoimmune neuromuscular hyperexcitability. This case highlights that this is a treatable condition.
