Case ReportsIsolated orofacial dyskinesia: a methylphenidate-induced movement disorder.
We report a case of orofacial dyskinesia in a 6-year-old female with attention-deficit-hyperactivity disorder who received a low dose of methylphenidate. The orofacial dyskinesia appeared immediately and subsided rapidly on the same day in an "on-off" fashion and on 3 separate days when methylphenidate was taken. To our knowledge this particular side effect has not been described previously and might represent an unusual type of brain response or sensitivity.

Cluster headache, the most painful of the primary headaches, is a disorder with well-known diagnostic criteria. The condition usually begins in the second decade of life; the prevalence of childhood onset is approximately 0.1%. A 7-year-old female who suffered daily from severe strictly unilateral right orbital attacks lasting approximately 30 minutes associated with autonomic symptoms is reported herein. ⋯ According to the classification and diagnostic criteria for headache disorders of the International Headache Society the child fulfilled the criteria for episodic cluster headaches. The pathogenesis, clinical manifestation, autonomic features, genetics, and family history of cluster headaches during childhood are reviewed in this report. Prophylactic medication and symptomatic treatment options are discussed, especially concerning the rationale of use of steroids in children with cluster headaches.

Neurologic outcome of choreoathetoid encephalopathy after cardiac surgery.
Postoperative encephalopathy with choreoathetosis is a serious neurologic complication of childhood cardiac surgery. An inadequate understanding of the long-term outcome has limited family counseling and the institution of intervention strategies. Our objective was to define the long-term neurologic, cognitive, and behavioral outcome in this group of patients. ⋯ Of the 36 cases identified of which three were deceased, four were abroad, and eight were lost to follow-up, 21 families were approached, and 15 of the 21 (71%) consented to testing. We found pervasive deficits in memory, attention, and language, with a median full-scale IQ of 67 (range = 40-122), as well as in motor function, including persistent dyskinesia in seven of 15 (47%). The pervasive and enduring cognitive and motor deficits in survivors of postoperative choreoathetosis caution for guarded predictions of outcome and highlight the need for careful neurologic and cognitive evaluation in all children with choreoathetosis after open heart surgery.

Comparative StudyPediatric migraine equivalents: occurrence and clinical features in practice.
Migraine equivalents of infancy, childhood, and adolescence are recognized periodic, paroxysmal syndromes without associated headache that are thought to be migrainous in etiology. Five such equivalents are presently recognized. Their clinical features and relative frequency in ambulatory pediatric neurology practice have not been well documented. ⋯ There was variation in the age of onset of a particular equivalent with considerable overlap observed. Coexisting more typical migraines were observed in from 10% (benign paroxysmal torticollis) to 70% (abdominal migraines/cyclical vomiting) of the cases. In conclusion, pediatric migraine equivalents occur with relative frequency in ambulatory practice, possessing discrete clinical features that have a clear relationship to more typical migrainous phenomena.

Subdural hematomas are uncommon in term infants. The study objectives were to evaluate risk factors for and clinical significance of small subdural hematomas observed on computerized tomography. During a 3-year period, 26 near-term and term nonasphyxiated infants were found to have a subdural hematoma on computed tomography. ⋯ At discharge, nine infants with subdural hematoma exhibited an abnormal examination, i.e., mild hypotonia (n = 7) and Erb's palsy (n = 2). The clinical syndrome attributed to subdural hematoma was most often a subtle clinical problem. The presence of subdural hematoma documented by computed tomography is not necessarily always indicative of birth trauma and may occur as sequelae of an otherwise uncomplicated delivery.
