Radical surgery is the most important treatment modality for ependymoma. The benefit of adjuvant radiotherapy and/or chemotherapy following a gross total resection of a low grade intracranial ependymoma is uncertain. Since 1990 we elected to defer adjuvant therapy in 7 pediatric patients with a median age of 7 years (range 3-16 years) who had a radical(More)
Some drugs currently used to treat tics in pediatric patients have drawbacks, including the risk of side effects. New therapeutic options with better safety profiles are needed. Levetiracetam is an antiepileptic drug with atypical mechanisms of action that might be beneficial for this indication. We evaluated the effects of levetiracetam on motor and vocal(More)

Tourette Syndrome is a familial neurobehavioral disorder characterized by fluctuating involuntary motor and/or vocal tics. The most commonly used medications to treat Tourette's syndrome are haloperidol, pimozide, fluphenazine, and clonidine, all of which may have considerable side effects. We enrolled 450 patients with tics/Tourette's syndrome to be(More)
OBJECT The objectives of this multicenter study were to monitor the performance of a 10-ml pump infusing intrathecal baclofen to treat 100 children with cerebral spasticity, to monitor complications associated with the pump, and to correlate pump-related complications with body habitus. METHODS Age at implantation of the pump ranged from 1.4 to 16.8 years(More)
Increasingly, spasticity is managed with surgically implanted Intrathecal Baclofen pumps. Intrathecal Baclofen pump revision surgery unrelated to programmable pump end-of-life is not uncommon, requiring special attention during pre-, intra-, and postoperative management. We aimed to identify and describe complications of Intrathecal Baclofen pump as well as(More)
Because of inadequate response to or intolerable side effects of oral medication, nine patients with segmental, generalized, and focal myoclonus were treated with intramuscular botulinum toxin type A. All patients were evaluated with neuroimaging, routine and limb-monitored electroencephalography, electromyography, evoked potentials and appropriate(More)
A patient with homocystinuria due to cystathionine beta-synthase deficiency developed severe progressive polymyoclonus and ataxia. To our knowledge, this is the first time polymyoclonus and ataxia have been reported in association with homocystinuria. Although cerebrovascular thrombosis is usually thought to be responsible for neurologic dysfunction in(More)
The purpose of this article is to describe outcomes of intrathecal baclofen therapy for 29 patients with cerebral palsy, focusing on impairments, functional limitations, and disability. Patients received individualized rehabilitation and were followed up to 24 months. The primary outcome measures were the Ashworth Scale and the functional skills and(More)
Some patients with an 18p- syndrome show dystonia, and a focal dystonia gene has been mapped to chromosome 18p. The authors evaluated the extent of the deletion in three patients with an 18p- syndrome and dystonia using 14 DNA markers on 18p. A common deleted area, covering the DYT7 locus, places the putative dystonia gene between the telomere of 18p and(More)
We report a case of dystonia with a partial deletion of the short arm (p) of chromosome 18 and androgen insensitivity. Neurologic findings in the 18p syndrome are reported to include mental retardation, seizures, incoordination, tremor, and chorea. A 15-year-old girl with a denovo 18p deletion [karyotype 46, XY, del (18)(p11.1)] developed progressive(More)
