Phototherapy and Photochemotherapy in Dermatology
The beneficial effect of ultraviolet (UV) radiation on the course of some skin diseases is well known for a long time. The progress in technology and development of irradiation units that radiate UV-rays of special wave-length increased the possibility of phototherapy. Phototherapy as a method of treatment in dermatology has become widely used because of its relative safety and simplicity in comparison with photochemotherapy which is used only in specialized centres. In addition the paper discusses different kinds of treatment with UV-radiation.
