Dr. Nevlllo Wood records In tbo London Lon-don Lancet a cato In which n considerable consid-erable over-growth of hair on a woman' wom-an' face was removed by applying the Itoentgen raya. There wero ten sittings per week ot ten minutes each, the face snd neck being protected with a leas-foil leas-foil mask, except whero tho ray were Intended to act After fourteen ex-posures. ex-posures. It was noticed that the dnrkcr hairs had lost some of their luster, nnd In a week's time there was an obvious lessening In their nuiubcr Tho hnln became brlltlo nnd pale In color, with atrophic bulba There wat a slight rod-dcnlng rod-dcnlng of the tkln during thlt period After forty-five cxpoturct, tho whole of a very thick downy and hairy growth had dlaappeircd, except nine hairs which remained at least a week after the total removal of the other. They were found, howover, to be readily read-ily separated at the bulbs, being re talncd In position by a mora superficial superfi-cial part of the root-sheath After ceasatlon of the treatment, only n fow thick hairs had returned, and these wero removed with the wtll known process ot destroying them by tho electric elec-tric neodle Dr. Wood Is ot the opinion opin-ion thst the treatment Is neither disfiguring dis-figuring nor painful, and thinks that about twenty will clear the ground tor tho tire ot the electric needle, and that between thirty or forty exposures will probably result In permanent baldness. The rays also promise to be ot service as a rurallvo agent In the treatment ot certain diseases of the skin. It seems certain that cases ot lupus are much benefited, It not cured, by being treated by periodic applications of the X rays, nnd the hope Is also held out that obstinate ob-stinate cases ot eczema, rlngwnrm.etc, will provo amenable to the same treatment treat-ment At Copenhagen a number of case ot lupus have been successfully treated by exposure to sunshine, and as the Itoentgen rays have on effect like sunshlno on the skin, It Is thought that they may prove equally efficacious. |
