Serum zinc levels are lower in children with febrile seizures than in those with epileptic seizures and normal children. Zinc supplementation of children at risk of febrile seizures requires further study.
Primary tumors of the heart are exceedingly rare with a prevalence rate of around 0.01% in autopsy studies. A majority of primary cardiac tumors are benign. Rhabdomyomas are the most common of benign pediatric cardiac tumors. A newborn female infant presented with perioral cyanosis and respiratory distress. She deteriorated progressively. The infant expired, and at autopsy, dissection of the heart revealed a large tumor mass in the interventricular septum. Histologically, the mass showed the classic "spider cells," and a diagnosis of cardiac rhabdomyoma of childhood was established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
