ObjectiveTo evaluate the signs/symptoms of different stimulant toxicities in children to determine differences among them.DesignObservational, retrospective, single-center case-series.SettingThe only referral hospital for pediatric poisoned patients in Tehran, Iran, covering 12.5 million permanent and 6.5 million temporary residents.PatientsAll children between 2007 and 2012 were evaluated. Their clinical findings, laboratory tests, electrocardiogram, and outcome were evaluated.InterventionsNone.Measurements And Main ResultsA total of 147 patients were enrolled (115, 24, three, and five with methamphetamine, methylphenidate, ecstasy, and unknown stimulant toxicities, respectively). Median (interquartile range) age of the methamphetamine- intoxicated children (16 mo [22-42 mo]) was significantly less than those with methylphenidate toxicity (66 mo [33-105 mo]). Almost 79% of the patients had ingested the stimulant, whereas 9% had passively been exposed to the methamphetamine smoke. The frequency of stimulant toxicity had significantly increased during the 5-year period of the study. Restlessness, mydriasis, stereotypic movements, and talkativeness were the most common signs and symptoms. Whereas bruxism only seen in 66.7% (95% CI, 21-94%) of ecstasy users, the prevalence of restlessness, sweating, and tremor was also more in this group of children. On the other hand, mydriasis and stereotypic movements were more common in crystal-meth patients by 76.5% (95% CI, 68-83%) and 53% (95% CI, 44-62%), respectively. A comparison between different routes of crystal-meth intoxication showed that flushing was more common in those who had passively/actively smoked/inhaled methamphetamine (odds ratio, 6.3 [95% CI, 1.5-26]). Palpitation was more seen in methylphenidate toxicity by 12.5% (95% CI, 4-31%). Restlessness was more detected in toddlers, whereas talkativeness and ataxia were more common in older children. Nineteen children (21%) had prolonged QTc according to normal values in different ages. None of them died.ConclusionsMore studies are warranted to evaluate the frequency and outcome of this poisoning in children. Educational preventive programs are also recommended.
