Spring and summer junction of the season, the sky also began to drift up the sky pollen and willow flakes, although as elegant as snowflakes, but the bitter people allergic to it, here itchy there are some red bumps; there are also people to change to a new cosmetic not long, the face began to be red and swollen; some love to eat fish and shrimp and mango friends, to enjoy these delicacies also how long, the body appeared in a large area of the wind pimples… …Allergies, it seems, are ever-present and ubiquitous! Below, let’s learn about allergic dermatosis. First, what is allergic dermatosis Allergic dermatosis is a skin disease caused by allergens, specific allergens can be divided into contact allergens, inhalation allergens, food allergens and injected allergens four categories. 1, contact allergies such as some people contact nickel, chemicals, cosmetics, with watches, nickel-plated metal, and even some people wear jeans, where the head of the button sticking to the navel will also cause allergies. 2, inhalation allergies such as inhalation of pollen, and furry toys, dust, dust mites. 3, ingested allergies that eat into the allergy, such examples are very many, thousands, tens of thousands of species can be, some people are even allergic to rice, white flour allergy, allergic to beans, allergic to animal protein. 4, injection allergy such as injection of serum vaccine or a certain drug can appear allergic reaction, the most common penicillin allergy and injection of rabies vaccine caused by allergy. Each type of allergen can cause the corresponding allergic skin disease, the main performance is a variety of dermatitis, eczema, urticaria, drug rash, contact dermatitis. The number of people suffering from the disease is gradually increasing due to atmospheric pollution, pesticide abuse, premature use and abuse of antibiotics in infants and young children, increasing abundance of food or increased mental stress. In addition, because of the increasing use of cosmetics in recent years, cosmetic skin diseases are becoming increasingly common. There are mainly cosmetic contact dermatitis (accounting for more than 50%), cosmetic photosensitive dermatitis, cosmetic skin pigmentation abnormalities, cosmetic acne, cosmetic hair damage and cosmetic nail damage. The causes are allergy (unpredictability), irritation (shoddy products), and improper use (frequent exfoliation of the stratum corneum, excessive blemish removal, etc.). In a season such as the current one, when daylight is suddenly enhanced at the turn of spring and summer, some people do not adapt to this change and become allergic; wind and sand, although they do not cause allergies, can irritate the skin and cause uncomfortable symptoms. People often wonder why I get rashes when I eat fish and shrimp, but others are fine. Allergic skin diseases are mainly related to genetic and environmental factors (including inhalants, food, drugs and infections, and even climate change and emotional changes). Allergies often have great individual variability and tend to occur in sensitive individuals. Common allergens and allergens check Common allergens include the following categories: 1, food: fish, shrimp, crab, eggs are common, followed by certain meats and some plant foods such as strawberries, cocoa, tomatoes, pineapple, coffee, or garlic and other condiments. 2, drugs: common cyanide, cocoa, tomatoes, pineapple, coffee, or garlic and other condiments. 2, drugs: common penicillin, serum products, sulfa, dysentery, aspirin, etc.. 3.Infections: including viruses, bacteria, parasites and so on. 4, physical factors: such as cold, heat, sunlight, friction and pressure and other physical stimuli. 5, animal and plant factors: such as insect bites, nettle irritation, or fine such as animal dander, feathers and pollen. Allergen examination is divided into contact allergen examination, mainly through patch test to check contact allergens, such as cosmetics, jewelry, clothing, and decoration caused by allergies. Inhalation allergens are examined by drawing blood for laboratory tests, or by skin tests similar to the penicillin skin test. Food allergens are also checked in this way. However, in some cases, allergens cannot be detected either. Such as a lot of dermatitis, eczema similar to allergic skin diseases, but not really skin allergies, so this situation is often check allergy is not found, because its pathogenesis is not an allergy, is a stimulus, is a variety of irritants caused by skin irritation, or there are a number of chemical substances in contact with the skin or eaten into the body can be caused by some of the inflammatory mediators of the release of the body, causing dermatitis or urticaria directly. It is similar to allergy. It is similar to allergy, but cannot be detected. In addition, due to the limited number of substances checked mainly for the most common allergens, if the substance you are allergic to is not included in these substances, then it cannot be checked either. Food is the main cause of allergies, and avoiding all foods suspected of having allergic potential in order to cure the disease is obviously not a smart, sensible approach. It is then particularly important to determine which food is allergic. You can try to apply the following methods: 1, food record method: the monthly food such as rice, eggs, shrimp, chicken, cucumbers, tomatoes, etc., food time (such as month, day, time, etc.), allergy occurs one by one to record. Once an allergy occurs, the relationship between the food and the allergy can be identified from the record. Generally, more attention should be paid to the food eaten 12-24 hours before the allergy occurs. This method is simple and easy to master, but it is difficult to get accurate results. 2.Food exclusion method: first use commonly eaten without allergic food, that is, food containing only rice, noodles, soybeans, potatoes, peas, carrots, pumpkin, zucchini and other rarely allergenic things. Try not to add flavorings and other potentially allergenic ingredients within the meal. Eat this light food for 3 weeks straight. Generally, if a food allergy is confirmed, after three weeks of such a diet, the rash should no longer occur. At this point, you can begin to add the suspect foods one by one to the above light foods. Observe each food for 5 days to see if any allergic reaction occurs. If an allergic reaction occurs after adding a suspected food, the test result for that food is positive and should be recorded. Each suspected food should be tested individually because a person may be allergic to two or more foods at the same time. Allergic foods identified by this method should preferably be eaten and observed again to further determine whether it is the actual food causing the allergy. It is also advisable to consume and observe the allergic food identified by the food record method again to make the results more reliable. The identified allergy-causing food should not be eaten again in the future. After a period of time this allergic food is expected to control the occurrence of its allergic reaction. 3. Skin test: The method of skin test for ingested group is simple, only using an empty needle to inhale the skin test solution containing milk, rice, soybeans, etc., and then the subject’s upper arm to do more than one puncture to observe the allergic reaction of a variety of foods. However, due to the ingestion of rice, flour, beans, etc. in the body of digestion and absorption is a complex process, the physiological and biochemical changes that occur, and can not be fully reflected in the process of ingestion of the group of subjects, so the results, although positive, also need to carry out a comprehensive analysis of the clinic in order to determine whether to cause allergies to the food. Third, how to treat allergic skin disease The main principle is to remove the cause of the disease, control scratching and avoid stimulation. General prevention and treatment include the following points: 1, as far as possible to find the cause of the disease, can be avoided should try to avoid, can not be avoided should be removed. Avoid all kinds of easy to cause sensitization and stimulating food, such as fish and shrimp, strong tea, coffee, alcohol and so on. 2, avoid all kinds of external stimuli, such as hot water scalding, violent scratching, excessive washing and so on. There are a lot of friends after the allergy occurred on their own with scalding water, wash with salt water or pepper water, or simply scratching desperately until scratching bleeding, these measures are very effective for a period of time, but after stopping the original lesions will be heavier, and then further to stimulate the big, leading to the occurrence of a vicious cycle, the deterioration of skin disease. 3, some patients with clear allergens can be desensitized treatment. When allergy occurs, the main symptomatic treatment, including giving anti-allergy treatment, and oral or intramuscular injection of various anti-allergy drugs, at the same time can be given some corresponding topical drugs such as glycerite lotion or hormone topical drugs. For those who are allergic to allergies, some common anti-allergy drugs such as paracetamol, petroleum jelly (imipramine), cetrimide (cetirizine), kelotonin (loratadine) and so on can be taken according to the instructions in case of allergy to achieve effective relief. However, if there is more serious difficulty in breathing or even shock, it is necessary to go to the hospital urgently for treatment, including giving the appropriate amount of hormones. Fourth, how to avoid allergies 1, often allergic people usually belong to the allergic body, is caused by a specific protein in the body, this body is unchangeable, the best way to prevent skin allergies is to reduce contact, go out and try to do a good job of protection. Allergy-prone people in the spring should be less sunshine, less to the park and other pollen, willow flakes more places to go. 2, do not eat food that may cause allergies, try to cook what you eat, eat as little seafood as possible, avoid eating animal head and hoof parts. 3.Keep the indoor temperature and humidity appropriate, try to avoid contact with substances that may cause allergies, try to wear cotton, soft, loose clothing. 4, after the house is newly renovated due to the formaldehyde contained in these chemicals, need to move in after a period of time to live. 5, clean home comfortable indoor environment than the natural outdoor environment is more unfavorable to allergies, it must be known that a variety of textiles in the home with textile furniture, pillows, carpets, closed windows, as well as warm, humid space, as in the home to put an allergy time bomb. Studies have shown that indoor air pollution is more than 10 times greater than outdoor pollution, and it has a huge impact because we usually spend more than 90% of our time indoors. Therefore, it is necessary to carefully clean up the places where allergens gather at home (bedding, carpets, kitchen, restrooms and other wet places and air conditioning filters are the most likely location), and then wash them clean. 6, to keep the skin moist, you can apply some moisturizing effect of the lotion.
