_Re_ organic signs in Shell-shock cases, Oppenheim warns practitioners and experts against undervaluing war neuroses. He does not like to have them set down in too offhand a way, as hysteria, wish-fulfilment, and simulation. Hysteria is not likely, according to Oppenheim, in cases with permanent cyanosis, disappearance of the radial pulse, trophic disturbances, hyperidrosis, alopecia, fibrillary tremors, myokymia, cramps, dilated and sluggish pupils, and weakening of tendon reflexes. Hyperthyroidism also has been found by Oppenheim. Shell-shock, explosion on left side: Sensory disorders especially on left side; ecchymosis of right (uninjured) leg, possibly conditioned upon shock of left hemisphere. =Case 258.= (GERVER, 1915.) An artillery officer had had a shell burst to the left side of his horse, which veered to the right but did not fall. The officer’s left hand immediately became so numb and weak that he could not hold his reins with it; it shortly became more painful. The left foot showed a tendency to the same anesthesia and paresis. Curiously enough, a number of punctate hemorrhages appeared on the right thigh and lower leg, upon the outer aspect. According to Gerver, these hemorrhages into the skin of the _right_ leg may have something to do with a disturbance of circulation related with effects wrought upon the _left_ hemisphere. During the course of the disease, pains occurred not only in the left arm and leg but also in the right leg. _Re_ brain injuries produced by shell explosions without external wound, Roussy and Boisseau have not found a single clinical instance amongst 133 cases observed, which suggested cerebral softening, or even hemorrhage into the brain substance, the cord substance, or the meninges. These 133 cases were observed in army neurological centres and contained instances of (_a_) mental disease (confusion, delirium, amnesia), (_b_) nervous disease (astasia-abasia, tremors, paralyses, contracture), and (_c_) an intermediary group (either mental confusion with stupor, or hysterical deafmutism). Shell-shock; unconsciousness: Hysterical deafness, speech-disorder, gait. Recovery by reëducation. Brief relapse to deaf-mutism at noise of drums. Improvement. Relapse to numerous and severe hysterical symptoms at small guns fired on King’s birthday. Improvement. Speech wholly regained in a quarrel. Recovery. =Case 259.= (GAUPP, March, 1915.) A musketeer, 22, had been blind for a time at 11 on account of some spinal cord disease. He was a soldier up to Christmas eve, 1914, when he was hurled backward in a trench in the Argonne by an exploding hand grenade. He lay unconscious for several hours, though without sign of physical injury. Coming to his senses, he worked himself out of the trench and crawled to another, but again fell unconscious. When he awoke he was in a physician’s care in quarters, to which he had been taken by ambulance men. Thence to the field hospital, and then to a private hospital at B.
