Dermatology @ 480

Phototherapy uses ultraviolet light (UVB and UVA )to treat a number of skin disorders. Dermatology on Ward has a whole body narrow band UVB machine which uses a specific wavelength of 210nm UVB to treat skin disorders affectring the body and a hand and foot UVA machine to treat disorders of the hands and feet. Hand and foot PUVA involves soaking the hands or feet in a solution containg methoxypsoralen and then exposing the involved skin to UVA light. The UVA light activates the methoxypsoralen leading to an improvement. These treatments are usually used after topical treatment has failed and before oral treatment is considered. The most common disorders treated are eczema and psoriasis but other disorders such as vitiligo and itching will also benefit. Treatments are needed 2 to 3 times each week for a period of of 8-12 weeks.
