During times of war certain syndromes, relegated to nonrecognition or oblivion in peacetime, require renewed emphasis. Among these is a peculiar vasomotor disturbance, for which a generally accepted name is lacking. It is my belief that Vulpian's¹état physiopathique, Weir Mitchell's² causalgia, Sudeck's³ atrophy, Leriche's⁴ post-traumatic painful osteoporosis, the peripheral trophoneurosis⁵ and the chronic traumatic edema⁶ are only different manifestations of an essentially identical vasomotor disturbance.
