脊髓肌阵挛是一种罕见病以突发、节律性、单个或节段神经支配肌肉的不自主收缩为特征。其平均节律为1次/秒,2～600次/分。随疲劳、情绪紧张而加重,通常不受感觉刺激或活动的影响,睡时阵挛停止。肢体和躯干肌的局灶肌阵挛发作与病毒性疾病的关系可在嗜睡性脑炎病程中见到。此外,在某种类型的病毒性脑脊髓炎和脊髓炎亦可见到脊髓肌阵挛。人的病毒性疾病表现为脊髓肌阵挛在诊断上常难确定,然而影响胸段皮节的带状疱疹神经根炎可见此种发作。本文报道一例自限的脊髓肌阵挛伴人类T 细胞亲淋巴性Ⅲ型病毒/伴淋巴结病毒感染(以下简称HTLVⅢ/LAV)病例。患者,35岁男性,同性恋者,因腹部节律性“跳动”三周而入院,收缩频率40～70次/分,不对称、右侧较左侧明显,睡眠时持续,紧张时收缩加强,注射
Spinal myoclonus is a rare disease characterized by sudden, rhythmic involuntary contraction of the muscle that is innervated by segments or nerves. The average rhythm of 1 times / second, 2 ~ 600 beats / min. With fatigue, aggravating emotional stress, usually without feeling the impact of stimulation or activity, sleep when clonus stop. The relationship between focal myoclonus episodes of limbs and trunk muscle and viral diseases can be seen in the course of lethargic encephalitis. In addition, spinal myoclonus can also be seen in some types of viral encephalomyelitis and myelitis. The manifestation of human viral disease is the diagnosis of spinal myoclonus, but this can be seen in herpes zoster radiculitis, which affects the thoracic dermatome. This article reports a case of self limiting spinal cord myoclonus with human T-cell lymphotrophic virus type Ⅲ / associated with lymph node virus infection (hereinafter referred to as HTLV Ⅲ / LAV) cases. Patients, 35-year-old male, gay, hospitalized for rhythmic beating of the abdomen for three weeks had a frequency of 40 to 70 beats per minute, asymmetry, significant left-hand side, sustained sleep,
