This patient was first brought to Jena November 23, 1914. An illegitimate child, a moderately good scholar, he had worked as a mason until he went into the army, in 1912. He worked as a soldier chiefly in the officers’ casino because he got pains in his legs and knees in long drills. At the outset of the campaign, however, he withstood the heavy marching, although with difficulty. He was in his first actual skirmish September 20. A shell struck nearby and threw him several meters; whereupon he became unconscious and was carried away by the hospital corps. When he woke up he could not speak or hear. Ten days later, however, speech returned, and hearing returned in right ear; October, deaf in the left ear, and he could not hear a watch tick on the right side at a distance of 16 centimeters. He was examined at the otological clinic in Jena October 12, where the drum membranes were both found opaque, without reflexes or normal contours; hysterical attack on the caloric test. The next day, on the medical visit, there was a screaming attack. His plight seemed not so much simulation as one of traumatic hysteria. Again, after his stay at the nerve hospital, another hysterical outburst was produced by a hearing test with vestibular apparatus, in the ear clinic, February 6, 1915. The diagnosis was nervous deafness with involvement of left ear. The insomnia was successfully treated by sodium bicarbonate. There was a slight improvement in speech. In March body weight had improved, but there was a marked tremor of the right hand. In the next few months there was a progressive improvement in general well-being, in speech disorder, and in tremor. The auditory disorder remained unchanged. The man now works in his father’s garden. This case appears to show a combination of psychic and mechanical injury. There are severe hysterical auditory and speech disorders. Although the auditory disorder is of mechanical origin, the speech disorder appears to be of psychogenic nature. It is somewhat remarkable that the ear tests almost every time produce hysterical attacks in the form of convulsive crying. Rather unusual is the general cutaneous hyperalgesia, more marked about the ears. Shell-shock (distant, neither seen nor heard); left tympanum ruptured; semicoma eight days: Cerebellar syndrome and hemianesthesia. Recovery, nine months. =Case 218.= (PITRES and MARCHAND, November, 1916.) A lieutenant underwent “shell-shock” either at night or in the early morning, September, 1915, the shell bursting at a distance. He neither saw nor heard the shell, lost consciousness and was eight days semicomatose, failing to recognize his wife.
