In this way I have been called upon to treat a number of patients suffering from diabetes, who have come to me for the relief of pruritus \njlvae, or other dermatological con- ditions associated with this disease* Here, as well as in rheumatoid and lithaemic states, gouty conditions, neuralgias, etc, decided improvement can at times be noted. In chronic processes in which pain is a marked symptom, autoconduction or autocondensation, accompanied by local * La nforma medica, iSgS, No. 48, I APPLICATION OF HIGH-FREQUENCY CURRENTS 697 effluvia and sparking, massage with the glass electrode or metallic roller, frequently gives marked and prompt relief. In impaired nutrition and faulty metabolism the same gen- eral treatment appears to do good. In a variety of subacute and chronic inflammatory processes attended with exudation and painful thickening of tissues, local mild effluviation and electrode massage hasten the restittUio ad integrum. In Skin Affections. As a result of a close clinical study of over 250 cases treated in my office I am convinced: (i) That in a comparatively large number of dermatological affec- tions the local action of high-frequency currents aids in their cure. (2) In a limited number of patients in whom nutrition is at fault D'Arsonvalization or autocondensation helps to bring about a prompter removal of local lesions. (3) In parasitic affections, while it has an influence, I have not been able to convince myself that the results are prompter or better than in older methods. (4) That the broadest field of usefulness is in the markedly pruriginous affections, and in those intimately connected with the nervous system and associated with pain. (5) An important and, as I believe, a growing sphere is that filled by the high-frequency spark in the almost painless destruction of the small neoplasms, including naevi, moles, warts, tumors, and malignant growths, as well as in lupus and lupus erythematosus. I have for years advocated early and radical destruction of naevi moles and other congenital growths as a prophylactic measure against cancer. While I have seen disastrous results follow improper attempts at removal, I have never observed any- thing but benefit follow recognized methods of cure. In a paper read by Prof. W. W. Keen,^ twenty-five instances are given in which such growths degenerated malignantly, and were known to have caused death in at least eleven subjects. Patients who would refuse the knife will consent to the painless method here advocated, which leaves little or no scar. (6) Compared with the Roentgen ray, skin affec- tions as a whole are less benefited by these currents; but the two methods often enhance each other's influence. * The Danger of Allowing Warts and Moles to Remain Lest They Become Malignant, Journal of American Medical Association, June 7-10, 1904.
