This 12th annual volume, which resulted from a symposium on head trauma, deals chiefly with standard, well-known material on examination, clinical diagnosis, electroencephalography, angiography, medical and surgical treatment. The honored guest this year was Edgar A. Kahn, MD.
Unusual chapters discuss metabolic changes (McLaurin), with pointed remarks on necessity for giving salt solution after injury or operation; rhinorrhea (Lewin), with statistics supporting the view that operation should always be done even if the leak has stopped; serious and fatal football injuries (Schneider), which occur proportionately more in professional than in sandlot games, with indications that present helmets are inadequate. Kaplan's study of chronic residua of head trauma includes 35 pugilists who had had concussion. He believes that the "punchdrunk" syndrome is related more to preboxing personality than to blows to the head. Values of vigorous rehabilitation (even in aphasic patients) are pointed out by Rusk, Lowman, and Black. Flanigan and
