周期性麻痹为发作性以横纹肌弛缓性瘫痪为特点的一种肌病,常见为低钾型,发病时伴有血清钾浓度改常和心电图异常。文献未见有报道客观感觉障碍。最近我院收治两例低钾型周期性麻痹病人均伴有不同程度分布类型的感觉障碍,现报道如下:例一:曾××,男性,20岁。因四肢进行性无力两天急诊留观。患者于1987年4月14日早起觉全身无力,以双下肢明显,次日四肢无力加重至不能行走,双上肢抬举费力,自觉无肢体麻木感,无呼吸困难,觉大便较前稍费力,小便正常。病前无感冒无腹泻史,既往无类似病史。体查:甲状腺无肿大,未闻及血管杂音,心肺腹未见异常。神经系统检查:颅神经未见异常,左侧胸9以下痛触觉减弱,右侧正常,双深感觉正常。双上肢肌力Ⅳ°,双下肢肌力近端Ⅰ°至Ⅱ°,
Cyclical paralysis is a myopathy characterized by flaccid striated muscle flaccid paralysis, commonly seen as hypokalemia, with concomitant abnormalities in serum potassium concentration and electrocardiogram. There are no reports of objective sensory disturbances in the literature. Recently admitted to our hospital two cases of hypokalemic periodic paralysis patients are associated with varying degrees of distributional type of sensory disturbance, are reported as follows: Example I: had × ×, male, 20 years old. Due to limb weakness two days emergency observation. The patient became asleep early on April 14, 1987, with obvious weakness in both lower extremities. He became unable to walk after the weakness of the extremities on the following day. He had difficulty in raising his upper limb and felt numbness without difficulty breathing. normal. No cold without diarrhea before the disease history, no previous history. Physical examination: no swelling of the thyroid, no smell and vascular murmur, no abnormal heart and lung abdomen. Nervous system examination: no abnormality of the cranial nerves, pain in the left chest below 9 weakened, right normal, double deep feeling normal. Double upper limb muscle strength Ⅳ °, proximal lower limb muscle strength Ⅰ ° to Ⅱ °,
