DESCRIPTIONMany skin diseases respond to treatment with medications applied directly to the skin, or medications taken orally. In some difficult to treat skin disorders, ultraviolet light is prescribed as therapy. While in general, ultraviolet light is damaging to the skin, some diseases may show benefit from ultraviolet exposure.
Circadian rhythm disorders: The human body functions slightly differently at different times of day and night, according to an approximate 24 hour cycle. For example, the body's level of the natural hormone, cortisol, rises and falls at different times of the day. As well, a person's performance at some tasks is better at certain times of the day. Circadian rhythm is a term for the body's natural 24-hour cycle. Disturbance of the natural rhythm may show up as problems sleeping and waking at usual times.
To make the skin even more sensitive to the ultraviolet rays, a pill called a psoralen is sometimes taken (the opposite effect of a sunscreen). Once the psoralen is absorbed into the body, it makes the skin cells more susceptible to Ultraviolet-A(UV-A) light. The combination of psoralen pill and UV-A light is called photochemotherapy, or PUVA. The light is usually shone inside a booth, either in a hospital or clinic, to part or all of the body. While it is not known exactly how it works, there is first mild damage to the skin (like a sunburn) followed by healing of the skin later. Ultraviolet-B (UV-B) is a different wavelength of light used to treat some of the same skin disorders as UV-A. UV-B booths can be installed in the home setting.
Goeckerman treatment involves either painting effected areas with a solution of coal tar, or covering them with crude coal tar ointment and subsequently irradiating with ultraviolet (UV-B) light.
POLICYThe procedures and services addressed in this medical policy may only be rendered or ordered by Dermatologists.
