Naval gun-fire effects on seaman: Aphonia. Two recurrences.
Case 264. (Blässig, June, 1915.)
A seaman from the Derfflinger was brought into a naval hospital with loss of voice, December 22, 1914, able to speak only in a whisper. As a child he had had diphtheria, but recovered without complication. He had always had a very well-controlled voice. Early in December he had had a cold owing to sentry deck duty in bad weather. Two days after the shelling of Scarboro,—December 16,—while in the munition chamber of the big guns, he suddenly lost his voice. He had been greatly upset during the firing of the guns. In two weeks he recovered speech.
February 12, 1915, he returned to the hospital with a complete aphonia. This was immediately after the naval engagement in the North Sea. Three days later he was treated with electricity directly applied to the vocal cords. March 20 he was discharged with speech completely recovered. As soon as he went on leave, however, his voice was lost for the third time, and he was still aphonic at time of report.
Shell-shock MUTES observed, then DREAMED OF: MUTISM developed the SECOND NIGHT after shell explosion.
Case 265. (Mann, June, 1915.)
A volunteer of 20 was made unconscious for a short time by a shell explosion, but was still fully able to speak when brought to the field hospital.
In the second night after the explosion, however, he dreamed that he had lost his speech. In the ward, meantime, he had seen a number of shell-shock mutes. Following this dream of aphasia, came several weeks of mutism, which then cleared up. According to Mann, this is experimental proof of the psychogenic origin of a mutism.
