We report an adult patient presenting with choreiform movements 4 days after a large intravenous dose of cocaine. These movements were transitory and they normalized a week after admission. We believe this to be the first video case of acute chorea secondary to cocaine--a phenomenon popularly known as "crack dancing. " Cocaine abuse is associated with a wide range of movement disorders, including dystonia and exacerbation of Tourette's syndrome, multifocal tics, opsoclonus-myoclonus, choreiform movements, and stereotyped behavior known as "punding." Transient choreiform movements with a typical duration of 2 to 6 days are recognized by cocaine abusers themselves as crack dancing, but are infrequently reported. We present a video report of a patient with cocaine dependency and choreiform movements that normalized within a week of admission.
我们报告一名成年患者，在静脉注射大剂量可卡因4天后出现舞蹈样动作。这些动作是短暂性的，入院一周后恢复正常。我们认为这是首例继发于可卡因的急性舞蹈症视频病例——一种俗称“快克舞蹈”的现象。可卡因滥用与多种运动障碍有关，包括肌张力障碍、抽动秽语综合征加重、多灶性抽动、眼阵挛-肌阵挛、舞蹈样动作以及被称为“刻板行为”的“反复刻板动作”。可卡因滥用者自己将持续时间通常为2至6天的短暂舞蹈样动作视为快克舞蹈，但此类情况鲜有报道。我们展示了一名可卡因依赖且伴有舞蹈样动作的患者的视频报告，该患者的舞蹈样动作在入院一周内恢复正常。
