我是Polymorphic Light Eruption。对太阳晒超敏感尤其是午时。不用多晒,十分钟,我就会皮肤红肿,会痒。还好是问题出现在手臂上。我问过医生为什么会酱,医生说,我是吃错anti-biotic(抗生素)而引起的,他也告诉我不能吃含有Tetracycline的抗生素。目前医学没药医的,也会跟我一辈子。医生建议我用SpectraBAN SPF60防晒膏和尽可能穿长袖衣。我是不可能像很多人去海边游泳。
Polymorphic Light EruptionThis is the commonest cause of sunlight reactions. In its mild form it is often described as ‘prickly heat’ by patients, but it can be more severe and persistent. It causes itchy red bumps, which often join together, to come up usually a few hours after sun exposure. It can affect any area of skin exposed to sunlight, though in m any sufferers some areas of skin get the rash whilst others may be more resistant. It often causes problems only on hot holidays, tending to last for up to a week or so after one returns home. Some patients have the problem in the UK often throughout the Spring and summer, usually from around Easter until September or so. It is common, affecting to some extent around one in six young women , and can start at any age in men or women. The ‘allergic’ skin reaction to the sunlight is to the ultraviolet part of the sunlight. There are two types of ultraviolet in sunlight , A (UVA) and B (UVB). In most patients, the rash is triggered by UVA so, for many people, the only sunscreens that work are 4 or 5 star UVA protective sunscreens (the SPF (sun protection factor) only tells you about protection against UVB). In severe cases, treatments include oral steroids and ultraviolet desensitisation therapy: the choice of treatment depends on the exact features of the rash in an individual. |
