Summer is coming, the weather is hot, sweating like rain, wet skin will inevitably be infected by a variety of fungal bacteria. In addition, thin clothing, exposed skin increases, giving a variety of mosquitoes and insects can take advantage of the opportunity. Therefore, summer is the high season for a variety of skin diseases, today we will teach you how to deal with several summer skin diseases. Papular urticaria Causes: Most of the onset is mainly related to insect bites, such as mosquitoes, bedbugs, fleas, lice, mites, midges and other bites caused by allergic reactions, so also known as insect bite dermatitis. Insects bite the skin after the injection of saliva, so that people allergic to these substances produce the disease, is a common allergic skin disease in infants and children, but adults can also suffer from this disease. It is a delayed allergic reaction that takes about 10 days to sensitize, at which point the bite contributes to the development of the rash. Symptoms: The lesions are mostly on the trunk, extensor side of the limbs, clustered or scattered. They are slightly fusiform red lesions of green bean to peanut size, some may have pseudopods, often with small blisters at the top, and some become large, hemispherical, elevated, tense blisters soon after they occur, with clear content and no surrounding redness. The rash is skin-colored or light red or light brown, and in some cases it is a hard, chestnut-sized papule that is swollen and swollen after scratching. Old and new rashes often coexist. In young children, the rash is usually very red and swollen, with large blisters, often with severe itching that affects sleep. Scratching can cause secondary infection. The rash subsides after 1 to 2 weeks, leaving temporary hyperpigmentation, but a new rash can occur one after another, making the disease prolonged. Often recurring, generally no systemic symptoms, local lymph nodes are not enlarged. Prevention methods: 1, should be good personal hygiene, diligent change, diligent washing, diligent drying bed sheets, quilts, the day is hot, switch to rattan mat, bamboo mat, etc., must pay attention to insecticide treatment. Children’s skin is more delicate, often use disinfectants may also have side effects, the simplest way is to soak all the bedding, including coolers, rattan mats with boiling water for a night, and then wash. 2, the family has a pet, must remember to often give the pet bath, disinfection, or sent to the veterinary hospital to do a medical examination, to check possible hidden dangers. 3, indoor stay dry, diligent ventilation, must remember to often open doors and windows, adhere to the ventilation, light, especially in the use of air conditioning more attention to indoor ventilation, ventilation. Try to simplify the layout of the bedroom to facilitate dust removal, it is best not to lay carpets indoors, do not place tapestries and other things that tend to accumulate dust in the home. 4. Exercise more to strengthen your body and improve your immune system. Ringworm Triggers: Ringworm is a clinically extremely common dermatophytosis that occurs on the feet and/or hands. It is caused by a pathogenic filamentous fungal infection, and tinea pedis is more common than tinea cruris. It has a tendency to be contagious and is strongly associated with close contact with the patient’s hand and foot parts and supplies, such as slippers, bath tubs, and foot rubs. Tinea versicolor is often transmitted from the patient’s own tinea pedis. Symptoms: The disease is divided into 4 types 1. Impregnated type: Mostly seen as white, vesicular, impregnated skin between the toes (fingers) with clear edges, removing the impregnated epidermis and leaving moist, bright red new skin. 2, blister type: mostly seen on the soles of the feet or palms of blisters, or even several blisters fused into a larger blister, clear borders, skin is not red, blister broken flaking. 3, scaly type: mostly flaking, there are a few blisters, blister dry flaking, clear border, inflammation is not obvious. 4, thickening type: mostly seen in the palmoplantar skin thickening, blistering and desquamation in summer, the skin cracking in winter. Prevention methods: In daily life, be careful not to wear other people’s shoes and socks, and wash the foot basin for one person only. People with tinea pedis should try to wash their socks separately from other clothes. People whose feet sweat easily should wear cotton socks, and should not wear non-breathable nylon socks or rubber shoes. At the same time, you should develop good hygiene habits, wash your feet every day, change your socks regularly, keep your shoes and socks dry, avoid bathing and swimming in unclean baths and swimming pools, and do not walk barefoot in public pools, bathrooms, gyms, etc. Try not to work in excessively hot and humid environments. Avoid using communal scissors and nail clippers. Contact dermatitis Causes: Contact dermatitis is an inflammatory reaction that occurs at the site of contact or even beyond after the skin or mucous membranes come in contact with an exogenous substance. It is a delayed metaplasia with a certain latency period for onset, and symptoms often appear only a few days after the first contact. Symptoms: Edematous erythema, papules, and blisters of various sizes occur at the site of exposure. If the contact is gas or dust, the lesions mostly occur on exposed parts of the body, such as the back of the hands, face and neck. Sometimes, similar dermatitis can occur when the contact is brought to other parts of the body, such as the vulva and waist, due to scratching. Prevention: People who love to sweat, it is best to put a layer of sweat-absorbing cotton cloth on the cooler before going to bed. In addition to mite bites, some people also have allergic reactions to grass and reed mats, the skin will appear bean-sized pale red bumps, itchy, therefore, people with allergic reactions should sleep on bamboo or rattan mats. The reason: solar dermatitis, also known as sunburn or sun spots, is a photosensitive skin disease, an acute inflammatory reaction to normal skin after exposure to the sun. In summer, the amount of ultraviolet light in the sun suddenly increases, and the body’s sensitivity to ultraviolet light also increases. Under the action of UV light, epidermal cells are damaged, proteins are denatured and decomposed, and capillaries are dilated and congested, leading to the development of dermatitis. The disease is most common in late spring and early summer, and is more common in children, women, skiers and water workers. The intensity of the reaction is related to the intensity of light, duration of exposure, individual skin color, body type, race and other factors. Symptoms: Skin erythema on exposed areas such as face, neck and back of hands, especially forehead and cheeks, with corn-sized papules and mild desquamation, aggravated by sun exposure, even swelling and blistering, often painful and itchy, aggravated at night, and can cause infection when scratched. In mild cases, it heals within 2 to 3 days, but in severe cases, it takes about a week to recover. Individual patients may develop conjunctival congestion and eyelid edema. If the sunburn area is extensive, it can cause systemic symptoms, such as fever, chills, headache, weakness, nausea and general discomfort. The actual fact is that you will be able to get a lot more than just a few of the most popular and popular items. In particular, patients who already suffer from this dermatitis should apply sunscreen with SPF 15 or more, and those with severe photosensitivity need to use sunscreen with SPF 30 or more to protect their skin from strong sunlight stimulation. 2. The sun’s ultraviolet rays are most abundant from 10 a.m. to 2 p.m. daily, so go outside as little as possible during this time. If you must go outdoors, you should wear loose long-sleeved clothing and pants, and wear a sun hat, play umbrella, do a good job of protection. 3. People who are sensitive to light, after ingesting photosensitive substances, such as certain foods and drugs, or being exposed to the sun for a longer period of time, will also have symptoms of solar dermatitis in exposed areas of the skin, so avoid these irritants. Once the symptoms of solar dermatitis appear, do not immediately bathe with hot water to avoid aggravating the dermatitis symptoms, and do not scratch with your hands, because once scratched, infection can easily occur. You can use anti-itch and pain-relieving ointment to apply to the affected area under the guidance of a doctor. In addition, although lupus erythematosus and freckles are not photosensitive skin diseases, sunlight exposure can also aggravate the disease.
