In 44 men with a history of repeated occupational lead poisoning multidisciplinary clinical and laboratory investigations were carried out. The number of lead poisoning episodes was from 2 to 7. Apart from peripheral hypalgesia on the extremities (in 6 cases) no other neurological abnormalities were found. The motor nerve conduction velocity in the median, ulnar, radial, peroneal and tibial nerves was slightly slower in 27 cases and considerably slower in one case. Slowed down conduction velocity was most often observed in 2 nerves (12 cases) and in one nerve (9 cases), less frequently in three (4 cases) and four (2 cases) nerves. In one case this slowing down was found in all five studied nerves. Conduction changes were found in 21 peroneal nerves, 15 ulnar nerves, 12 median nerves, 7 tibial nerves and 2 radial nerves. The authors think that for the evaluation of the condition of the peripheral neuron in cases of past lead poisoning it would be sufficient to determine the conduction velocity in the ulnar and peroneal nerves. Plumbism neuropathy have the character of subclinical lesions not impairing motor skill.
对44名有反复职业性铅中毒病史的男性进行了多学科临床和实验室检查。铅中毒发作次数为2至7次。除了四肢周围感觉减退(6例)外,未发现其他神经异常。27例患者的正中神经、尺神经、桡神经、腓总神经和胫神经的运动神经传导速度略有减慢,1例患者明显减慢。传导速度减慢最常出现在2条神经(12例)和1条神经(9例),较少出现在3条(4例)和4条(2例)神经。1例患者在所有5条研究神经中均出现这种减慢。在21条腓总神经、15条尺神经、12条正中神经、7条胫神经和2条桡神经中发现传导改变。作者认为,对于既往铅中毒病例外周神经元状况的评估,测定尺神经和腓总神经的传导速度就足够了。铅中毒性神经病具有亚临床病变的特征,不损害运动技能。
