Clinical uses of melatonin in pediatrics

Melatonin does not influence sleep deprivation electroencephalogram recordings in children

The electroencephalogram (EEG) is an essential diagnostic tool in children with epilepsy. The recording of a sleep EEG can increase the yield of EEG recordings in certain epileptic syndromes. The primary aim of this study was to assess the influence of melatonin on EEG recording (quality, EEG characteristics) and to assess its efficacy to induce sleep. Children with epilepsy or non-epileptic neurological patients requiring sleep deprivation EEG studies were enrolled into this prospective study at a tertiary University Hospital study. Sequential recording of sleep deprivation EEGs both with and without prior administration of melatonin was performed. A total of 50 patients (27 with epilepsy, 23 non-epileptic neurological patients) were included in this study (median age 9.5 years; range 1-18 years; male 28). The quality and EEG characteristics (abnormal findings, depth of sleep) were not affected by the use of melatonin. In total, 92 of 100 EEGs were successfully performed without significant differences between the two groups (six failures with melatonin, two failures without melatonin; p = 0.289).

CONCLUSIONS

We conclude that melatonin does not alter the quality of sleep EEG studies in children with epilepsy or suspected epilepsy. Melatonin does not increase the rate of successfully performed EEG studies in sleep-deprived children.

Psychopharmacology of autism spectrum disorders

At present, no evidence-based effective pharmacologic options are available for treating the core deficits of autism spectrum disorders (ASDs), which are best addressed by behavioral and educational interventions. However, such evidence exists for several of the frequently associated/comorbid symptoms such as aggression and severe irritability, hyperactivity, and repetitive behaviors, which can become a major source of additional distress and interference in functioning. This article offers information on the psychopharmacology of ASD that is current, relevant, and organized in a user-friendly manner, to form a concise but informative reference guide for primary pediatric clinicians.
