In the designation of “solar allergy” is included the group of the Fhoto- dermatosis which are a group of skin problems associated with an abnor- mal reaction to the ultraviolet (UV) radiation. There are several eruptions related to photossensibility that affect mainly the exposed the skin to the UV. They can be classified in four groups: 1. i  mmunological mediated photo- dermatitis • Eruption solar polymorphous; spring Juvenile eruption; actinic folliculitis; actinic prurigo; sun urticaria; Chronic actinic derma- titis; hidroa vaciniforme 2. photosensitivity-induced by chem- icals and medicinal products 3. d  ermatoses aggravated by light • Lupus; dermatomyositis; Darier disease; rosacea; melasma; liq- uen plan (actinicus); porfiria, etc. 4. g  enetic disorders (xeroderma pig- mentosum, etc.) 4 july 2018 www.revdesportiva.pt It is important to collect a good medical story about the evo- lution of the current episode, about similar previous personal or family episodes, about the prior or concomi- tant use of oral or topi- cal medication that may cause photosensibility, about the contact with certain local plants (e.g. contact with fig tree or lime). Besides the physi- cal examination, there might be needed to perform laboratory tests for identification of autoimmune diseases, phototests, including fotopatch. It is essential fig- ure out potentially photosensitizing oral medication. The most responsible drugs are the anti-inflammatory, emphasizing the piroxi- cam and analogous, but also antibiotics, specially tetracyclines and quinolones, cardio- vascular medications (thiazides, amiodarone, among others) and also neuropsychiatric. To treat the acute episode, it might be nec- essary to apply at the spots of the allergy topi- cal steroids, transiently (days), twice a day, at the places of allergy, or soothing lotions, for example, of calamine or aloe Vera, and avoiding the exposure of the affected area to the sun). It is sometimes necessary, in addition to antihistamine oral medication, a period of systemic steroids. For prevention proper photopro- tection is essential. It is advised the wear of suitable clothing with non-porous texture, with a design that protects the neckline, arms and forearms, and the hat, ideally of wide flaps that protects the neck, as well as the use of sunglasses with UVB and UVA protection a 100%. It is essential the protection of the exposed areas with high SPF (sun- screen protection factor), SPF 50+, The skin cancer is still the most common type of cancer There is a growing number of cases of skin cancer and, among of the several types of cancer, it is the one with the most impressive rise. There are more than 3.5 million cases in Europe every year. Make a safe sun exposure Avoid unnecessary exposure Look for shadow whenever possible and avoid the summer sun during the midday Wear protective clothes Include dark colors, clothes with long sleeves, hats with large flaps and sunglasses for protection from UV. For children, whenever possible look for clothes with protection from UV as well. Apply sunscreen Check if the sunscreen you are applying has a high sun protection factor, both for UVA and UVB. Remind that most of the sun screens only start acting about half an hour after the application and the effi- cacy lasts about two hours. Take care about the very fluid protectors, “transparent” or in “foam”, because they can give a false sense of security, specially if they are nor applied several times with several layers over the same skin area.
