[Acute pandysautonomia].

39 years old woman with onset of faint, numbness of the extremities was reported. Special test of autonomic functions, endocrinology, biochemistry and nerve biopsy were carried out. The diagnosis of acute pandysautonomia was made. Clinically it is characterized by dilated pupils, non-reactive pupils, orthostatic hypotension, positive noradrenaline infusion test and negative sweating test with atropine. These changes suggested the disturbance of generalized sympathetic post-ganglionic nerve. In other hand defective salivation and lacrimation, lower values of the ratio between the R-R interval, constipation and rapid constriction of pupils with pilocarpine were considered as evidence of failure of parasympathetic post-ganglionic nerve.
