Description
[edit | edit source]
UVR is a non-ionizing radiation and lies between soft x-rays and visible light in the electromagnetic spectrum. It has a wavelength of 10 nm 300/480 nm. The therapeutic part of ultraviolet spectrum are classified by International Commission on Radiation (CIE)[1] on the basis of dominant biological effects displayed by each region as :
UV - A 315 - 400 nm Encourage wound healing
UV - B 280 - 315 nm Skin erythematous region
UV - C 100 - 280 nm Germicidal region
Ultraviolet radiation obeys the law that governs all the radiations, they may reflect, scatter and are absorbed by molecular chromophores. The degree of absorption is generally greater for shorter wavelengths, shorter wavelengths penetrate less deeply. Absorption depends on the thickness of the epidermis and any pigmentation of the skin. Skin thickening due to lesions will result in increased scattering and absorption and thus reduced penetration.

Indication
[edit | edit source]
Acne[edit | edit source]
Acne is skin condition which presents pustules, papules and comedones blocking the hair follicles and sebaceous glands on the face, back and chest. Ultraviolet radiation may be given with the following aims :
- An erythema will bring more blood to the skin and improve the condition of the skin
- Desquamation will remove comedones and allow free drainage of sebum, thus reducing number of lesions.
- The UVR will have a sterilizing effect on skin.[3]
Modest improvement was observed with sunburn rays (UV-B) and slightly more with the combination of long ultraviolet radiation (UV-A) and UV-B.[4]
Psoriasis[edit | edit source]
It is a skin condition which presents localized plaques in which the rste of cell turnover from the basal layer through to the superficial layer is too rapid.
Treatment can be given using the Leeds regimen or PUVA
Leeds regimen[edit | edit source]
In the Leeds regimen the sensitivity of the patient's skin to UVR is increased by the local application of coal - tar, added to a bath prior to treatment
Clinical Presentation[edit | edit source]
add text here relating to the clinical presentation of the condition, including pre- and post- intervention assessment measures.
Resources[edit | edit source]
add appropriate resources here, including text links or content demonstrating the intervention or technique
