[The use of the Drionic apparatus for treating essential hyperhidrosis].

40 patients with essential hyperhidrosis of palms, feet and axillary spaces were examined. All patients were divided into 2 groups: with permanent or remittent manifestations of hyperhidrosis. The prolongation of latent periods as well as the decrease of evoked skin sympathetic potentials amplitudes was observed in group with permanent type of hyperhidrosis as compared with remittent type patients or with control individuals. All patients were treated with "Drionic" apparatus (General Medical Co, USA) which therapeutic effect was based on water ionophoresis action. The decrease of sweating was demonstrated in 82.5% of cases. The treatment of palms and feet hyperhidrosis was more effective than of axillary spaces. The therapeutic effect in permanent group was better than in remittent group of patients. The investigation of evoked skin sympathetic potentials before the treatment resulted in the conclusion about high prognostic significance of potentials in curative effects of "Drionic" device.
