Topiramate for the treatment of infantile spasms.

Topiramate is a new antiepileptic drug with a broad spectrum of efficacy. Reports on the use of topiramate for treatment of infantile spasms are limited. We prospectively followed 15 children with recently diagnosed infantile spasms treated with topiramate for efficacy and tolerability.

Toxic pediatric parkinsonism: report of a child with metabolic studies and response to treatment.

We successfully treated a child with parkinsonism secondary to cytosine arabinoside with levodopa/carbidopa and attempted to elucidate the pathogenesis of the disorder by sequential analysis of cerebrospinal fluid biogenic amines, sequential magnetic resonance imaging, and fluorodopa positron emission tomography, which revealed both permanent and reversible biochemical and structural alterations. The parkinsonian disorder resolved in 9 months. Metabolic changes and structural abnormalities on imaging studies were chronologically correlated with the clinical course.

Nitrazepam for the treatment of Lennox-Gastaut syndrome.

Lennox-Gastaut syndrome is a severe childhood epileptic syndrome with encephalopathy and multiple seizure types, which are often intractable to treatment. Most of these children will ultimately become mentally retarded and dependent on others for their daily care. Antiepileptic drugs are the mainstay of treatment, however, no particular drug is entirely effective.

Anterior ischemic optic neuropathy in children: case reports and review of the literature.

Anterior ischemic optic neuropathy, infarction of the optic nerve head owing to inadequate perfusion through the posterior ciliary arteries, is a common cause of visual loss in adults but is rarely reported in children, in part because the diagnosis is overlooked. We report two cases of young children undergoing chronic peritoneal dialysis, who suffered bilateral visual loss from anterior ischemic optic neuropathy. Predisposing local anatomic and multiple systemic factors included a small optic nerve head with little cupping, possible intraocular hypertension, and systemic hypotension, hypovolemia, and anemia.
