The Wassermann reaction was still strongly positive. Salvarsan, mercury, and iodide were continued. January 6, 1917, the plantar reflex had become flexor. The abdominal reflex returned. Babinski’s second sign (combined flexion of thigh and pelvis) was now the only evidence of organic disease. Further antisyphilitic treatment removed this sign also. February 28, the man was discharged fit for light duty, with unequal pupils and positive Wassermann reaction, and a complete amnesia for the four weeks following his blowing up in the trenches. _Re_ fitness for light duty, see remarks on Case 20 concerning desk duty for certain tabetics. _Re_ the premature or unexpectedly early appearance of neurosyphilis under war conditions, the early claims of some authors have not been maintained. In the above instance, the infection was at 16 and the shell explosion occurred at 26, namely, at about the right interval for the development of neurosyphilitic signs. Gerver states that military service brings out the lesions of paresis earlier than they would otherwise come. Bonhoeffer has been unable to show that cerebrospinal syphilis is favored in its development by the exhaustion factor. SHELL-SHOCK PSEUDOPARESIS (non-syphilitic). Recovery. =Case 26.= (PITRES and MARCHAND, November, 1916.) June 19, 1915, a shell exploded some distance from Lieutenant R. He remembers the gaseous smell, the bursting of several shells nearby and a sensation of being lifted into the air. When he recovered consciousness, he was in hospital at Paris-Plage, covered with bruises and scratches. They told him he had been delirious and had vomited and spat blood. June 24, his wife came to see him, but this visit he could not remember. Nor could his wife at first recognize him, he was so thin. He roused a few moments and recognized his wife, but relapsed into torpor again. Speech was difficult and ideas confused. A few days later he was able to rise; but his mental status grew worse, especially as to speech and writing, the latter quite illegible. There was insomnia, or, if he slept, war dreams. August 7, he began a period of five months’ convalescence passed with his family, depressed, given to spells of weeping, confined to bed or couch, unable to “find words,” conscious of his state and troubled about it, speaking of nothing but the war, and afraid to go out for fear of ambuscade. There was at first a slight lameness of the right leg. Although he could walk, he felt pain in the knee on flexing the right leg on the thigh. He walked holding this leg in extension. On going back to the colors, he was immediately evacuated to the _Centre Neurologique_ at Bordeaux, January 20, 1916. Examination found a bored, impatient, irritated man, vexed that a man who was not sick should be sent up “_comme fou_.”
