RESUMO
BACKGROUND: Parents of children with migraine have described a higher prevalence of sleep bruxism and other sleep disturbances in their children. The objective of this study was to use polysomnography to investigate the prevalence of bruxism during sleep in children with episodic migraine relative to controls. FINDINGS: Controls and patients were matched by sex, age, years of formal education, presence of snoring, arousals per hour, and respiratory events per hour.A total of 20 controls, between 6 and 12 years old, with no history of headache, recruited from public schools in Sao Paulo between 2009 and 2012, and 20 patients with episodic migraine recruited from the Headache Clinic at the Federal University of Sao Paulo between 2009 and 2012 underwent polysomnography.No intervention was performed before sleep studies.Among migraine patients, 27.5% experienced aura prior to migraine onset. The sleep efficiency, sleep latency, REM sleep latency, arousals per hour, percentage of sleep stages, and breathing events per hour were similar between groups. Five children (25%) with episodic migraine exhibited bruxism during the sleep study while this finding was not observed in any control (p = 0.045). CONCLUSIONS: Our data demonstrate that bruxism during sleep is more prevalent in children with episodic migraine. Further prospective studies will help elucidate the underlying shared pathogenesis between bruxism and episodic migraine in children.

Convulsions triggered by fever are the most common type of seizures in childhood, and 20 percent to 30 percent of them have recurrence. The prophylactic treatment is still controversial, so we performed a systematic review to find out the effectiveness of continuous phenobarbital and intermittent diazepam compared to placebo for febrile seizure recurrence. METHOD: Only randomized, double-blind, placebo-controlled trials were analyzed. The recurrence of febrile seizure was assessed for each drug. RESULTS: Ten eligible clinical trials were included. Febrile seizure recurrence was smaller in children treated with diazepam or phenobarbital than in placebo group. Prophylaxis with either phenobarbital or diazepam reduces recurrences of febrile seizures. The studies were clinical, methodological, and statistically heterogeneous. CONCLUSION: The effectiveness of phenobarbital and diazepam could not be demonstrated because clinical trials were heterogeneous, and the recommendation for treatment recurrence should rely upon the experience of the assistant physician yet
