Vitamin D therapy in cutaneous tuberculosis.

THE German occupation of Denmark prevented us from learning about the works of Charpy and Dowling until the summer of 1946, so out experiments with this form of treatment did not commence until a year ago. During this past year, on the other hand, we have treated all our lupus patients with vitamin D, and I am happy to be able to state that the result has been excellent. It will be appropriate to mention that with the Finsen treatment—^with concentrated carbon arc light and heliotherapy—^we had attained a recovery percentage of 80, and consequently the remaining 20% of the lupus patients to be treated with calciferol constituted a particularly crucial test for the new method. In the past year we have treated altogether 130 cases, and the difficulty will be evident from the long duration of the disease in these cases.
