title: Two cases of acute pandysautonomia.
abstract: Two men had acute nonprogressive pandysautonomia. Both of them showed orthostatic hypotension, fainting in upright position, pupillary disturbances, diminished sweating, anacidity, and impotence. Case 1 showed considerable but inadequate improvement within 31 months. Case 2 recovered completely after 11 months. Clinical and pharmacodynamic investigations suggested that the main lesion was located in postganglionic fibers in case 1 and in preganglionic fibers in case 2. The cause of this disorder is unknown, although both patients had undergone substantial weight loss.
