A case of tuberculous pleurisy associated with myoclonus and Quincke's edema due to isoniazid (INH) and isoniazid sodium methanesulfonate (IHMS) was reported. A 75-year-old man was admitted to our division because of chest discomfort and the left chest pain of one month's duration. A conventional chest roentgenogram revealed pleural effusion in the left thoracic cavity. The pleural specimen obtained from the left parietal pleura revealed caseating granuloma. Myoclonus suddenly appeared two months after the administration of antituberculous drugs for tuberculous pleurisy. Therefore, INH was discontinued. Three days later the patient's myoclonus disappeared and nine days later IHMS was newly administered. The patient abruptly developed myoclonus and Quincke's edema. IHMS was discontinued and 30 mg of prednisolone was simultaneously given. Two days later myoclonus disappeared and two days more later Quincke's edema was improved. The lymphocyte stimulation test using IHMS was positive. At that time, levels of serum vitamin B6 were within normal levels. These results suggest that myoclonus may result from epileptogenic action caused by INH or IHMS, and Quincke's edema may result from hypersensitive reaction associated with IHMS.

Three patients presented with a 25-, 15-, and 5-year history of restless legs syndrome (RLS) and periodic limb movements during sleep (PLMS). For 1, 4, and 5 years, they reported additional involuntary trunk and limbs jerks preceding falling asleep and occasionally during intrasleep wakefulness. Videopolysomnography revealed jerks during relaxed wakefulness arising in axial muscles with a caudal and rostral propagation at a slow conduction velocity, characteristic of propriospinal myoclonus (PSM). Jerk-related EEG-EMG back-averaging did not disclose any preceding cortical potential. During relaxed wakefulness preceding falling asleep and during intrasleep wakefulness, PSM coexisted with motor restlessness and sensory discomfort in the limbs. PSM disappeared when spindles and K-complexes appeared on the EEG. At this time, typical PLMS appeared every 20 to 40 seconds, especially during light sleep stages. PLMS EMG activity was limited to leg, especially tibialis anterior muscles, and did not show propriospinal propagation. In one patient, alternating leg muscle activation was also present. Jerks with a PSM pattern represent another motor phenomenon associated with RLS and different from the more usual PLMS.
