Each mid-year, the quantity of dermatology centers floods. In summer, high temperature, high stickiness, solid daylight, the climate where plants and creatures are in an enthusiastic propagation period, combined with a great deal of human perspiring, and the expansion of uncovered pieces of the skin, make summer a season for skin illnesses especially, skin treatments in summer.
Skin diseases caused by sun exposure
Sunburn
An acute damaging reaction to the skin after excessive UVB exposure (exceeding the amount of erythema) in the ice milk wet compress in the sun. Occurs in the late spring and summer, when traveling. Sun exposure occurs for 2-12 hours, strong sunlight, long time, high personal skin sensitivity, and skin lesions appear early.
It manifests as bright red edematous erythema with clear boundaries. In severe cases, blisters and burning may occur. After a few days, the erythema and edema subsides, followed by desquamation and temporary pigmentation. In severe cases, symptoms of general discomfort may also occur, such as fever, chills, nausea, tachycardia, and hypotension.
In summer, the sun is strongest from 9 am to 3 pm, and overexposure can cause sunburn. Skin pigments have a light-proof effect, so people with light-skinned skin may be overexposed to the sun for 15 minutes at noon in summer.
UVB is mostly blocked by the ozone layer, which is 100 times less than UVA. UVB is 1000 times stronger than UVA in causing an erythema reaction. The UVB radiation intensity increases with the increase in altitude, and the radiation intensity increases by 4% for every 300 meters of altitude increase. UVA is reflected by sand, ice and snow, concrete surfaces, roofs, and white platforms, and is stronger than UVB. Therefore, UVA may also cause sunburn in certain environments.
The erythema after ultraviolet radiation is mainly due to vasodilation, the epidermal cells are stimulated to trigger inflammatory factors, and the mediators are prostaglandins and cytokines.
Prevention/Relief and treatment of sunburn
Avoid excessive direct light exposure and take physical shading (clothing, parasols, and wide-brimmed hats), such as blue jeans with a sun protection factor of 50~60 (SPF means the efficiency of blocking UVB radiation); sunscreen Sunscreens have physical (titanium dioxide), chemical (para-aminobenzoic acid, etc.) and biological (vitamin E) shading ingredients. Sunscreen preparations with these three aspects are better. Pay attention to choosing sunscreens that also block UVA radiation; apply cold and wet compresses (ice milk) after sunburn, and externally apply hormones or prostaglandin antagonists, such as indomethacin solution. In severe cases, you can take anti-inflammatory drugs.
Idiopathic photosensitive skin disease Do not apply hormones externally
The polymorphic light eruption occurs in areas exposed to sunlight, such as facial protrusions, neck, back of hands, and extended sides of forearms, blisters, erythema, or papules, or plaques, or papules, a type of rash, which is related to seasons and light. It is seen in young and middle-aged women with intermittent recurrent episodes and obvious itching. Laboratory indicators of lupus erythematosus in individual patients.
A chronic actinic dermatitis is a group of chronic dermatitis and eczema skin diseases in the sun-exposed parts. It is more common in middle-aged and elderly men working outdoors. The distribution of skin lesions is consistent with sun exposure, and it is manifested as patches of papules and plaques. Gradually thickened into lymphoma-like, severe itching. The pathology can be manifested as pseudolymphoma.
Prevention and treatment of idiopathic photosensitive skin diseases
Strictly avoid sunlight, use high-efficiency and broad-spectrum sunscreens; use antipruritic and anti-inflammatory drugs for external use, and try not to apply hormones on the face, such as doxepin cream, indomethacin solution, and other drugs. Tacrolimus ointment, etc.; according to the severity of the disease, the internal medicines are selected in order: nicotinamide and beta carotene, hydroxychloroquine, or thalidomide, prednisone, azathioprine.
Photosensitive skin diseases.
Eat vegetables in appropriate amounts due to solar dermatitis caused by chemical, plant-based, and other substances, including phototoxic or allergic contact dermatitis, plant solar dermatitis, vegetable solar dermatitis, mud snail-solar dermatitis, Phototoxicity or allergic drug reaction, etc.
It is manifested as sunburn-like erythema on the exposed area, which may be accompanied by symptoms of general malaise.
There are more than 100 kinds of photosensitive substances: drugs, sulfa, chlorpromazine, digram, guanylate, amiodarone, tetracycline, etc.
Chemical substances: coal tar, pitch, pesticides, cosmetics containing fragrances, detergents, etc.
Plant-based sumac, psoralen, angelica, fig, celery, milk vetch, ash, fennel, mushroom, coriander, lemon, citrus, mustard, etc.
Prevention and treatment of photosensitive skin diseases: Avoid direct exposure to photosensitive substances and sunlight; each vegetable should not eat too much at one time, and change varieties frequently.
