Neurasthenic hyperalgesia after peripheral nerve injury.
Case 416. (Weygandt, January, 1915.)
A German volunteer, a sportsman, was under heavy shell fire after the middle of October, 1914, and was wounded in the upper arm in November, with an injury to the median nerve that occasioned severe pain. These strictly localized pains increased upon any sort of physical or mental strain. If he walked down steps he kept thinking he might have an accident, and then the pains set in with greater force. He became apathetic so that he did not eat, drink or urinate. If his head were touched he felt pain as if from an electric shock. He also felt the pain when he saw anybody approaching a door to close it, through apprehension of the noise. Meantime, the wound was well healed. The pulse was accelerated. The visual fields were only slightly contracted. The patient wanted to get well and go back to the service.
Weygandt regards this hyperalgesia after peripheral nerve injuries as neurasthenic.
Military training: Peripheral neuritis in lead workers.
Case 417. (Shufflebotham, April, 1915.)
Among fourteen cases of lead poisoning, members of the territorial forces, largely from North Staffordshire, was a patient suffering from peripheral neuritis. He had been in the dipping-house. Two years before going into the service he had been suspended for lead poisoning by the factory surgeon. Giving up his work at the pottery, he became a general laborer in a non-lead process factory.
Three weeks after enlistment, the man began to complain of pains, tenderness in the arms, weakness of the wrists, headache, giddiness, nausea, and constipation. The bowels were opened by a large dose of epsom salts. On blood examination the hemoglobin was found diminished 40 per cent; cells with basophilic granules were found to the number of 500 per cu. mm. The face was characteristically pasty. There was albuminuria. Alcohol could be excluded. The man had to be discharged.
