摘要
Parkinsonism is an uncommon movement disorder in childhood. Six unusual cases of acquired parkinsonism in hospitalized children are described. Clinical manifestations included an akinetic-rigid syndrome with and without tremor, the combination of parkinsonism and dystonia, and a parkinsonism-plus syndrome. Altered mental status, mutism, dysphagia, and sialorrhea were frequent associations. Etiologies included hypoxic-ischemic encephalopathy; haloperidol treatment with and without neuroleptic malignant syndrome; toxicity of cytosine arabinoside, cyclophosphamide, amphotericin B, and methotrexate; St. Louis encephalitis and other encephalitides; and a pineal tumor with hydrocephalus. Cranial magnetic resonance imaging results ranged from normal to profound cerebral and cerebellar atrophy with chemotherapeutic toxicity. The illnesses usually were severe enough to require pharmacotherapy. Incorrect diagnoses of depression or catatonia delayed treatment or aggravated the problem. Acute treatment included amantadine, levodopa/carbidopa with or without selegiline, diphenhydramine, or benztropine. The concentration of CSF homovanillic acid was normal in a neuroleptic-associated patient, but the level was low in an encephalitic patient. All patients demonstrated dramatic improvement, including two who were not treated; some had complete resolution of symptoms and none required continued antiparkinsonian drugs despite poor scores on the Unified Parkinson's Disease Rating Scale and the Modified Hoehn and Yahr Rating Scales. The causes of parkinsonism described are more common in a general pediatric hospital than the parkinsonism associated with the popularized Segawa syndrome.
