Papular urticaria is caused by allergies. Before the rash, most of the children went to the outskirts or rural areas to play, so it is also commonly called "pox". The bites of insects such as bugs, fleas, mosquitoes, and mites can cause allergies to people with allergies, especially children, who are more likely to have skin allergic reactions. There is a kind of small mites, which are often hidden in corn grass, straw mats, flour, and dust. Because of its small size, it is not easy to see with the naked eye, but if it is bitten, it can cause pimplic urticaria. A small number of children can also cause allergic reactions and papular urticaria due to eating foods containing intestinal parasites.
What is papular urticaria?
Papular urticaria is a common allergic skin disease in infants and young children. In summer, the temperature is high, many insects become active, and children with allergies can cause disease. Papular urticaria tends to occur on the trunk and limbs, but the head and face are less affected. The skin lesions are manifested as wind mass papules or wind mass blisters. Children often have severe itching, especially at night, which often affects sleep and makes them mentally disturbed.
Papular urticaria is also called urticaria lichen, baby lichen. It is a common allergic skin disease in infants and children, but adults can also suffer from this disease. Often several people in the same family have the disease at the same time. It occurs more frequently in spring and autumn. This disease is a disease named after its symptoms. In fact, this disease is insect bite dermatitis. The clinical features are scattered, slightly hard papules with small blisters on the top. There is a fusiform flush on the periphery, and itching consciously.
Papular urticaria is a skin disease that tends to occur in children. The etiology and pathogenic factors are unclear, accompanied by severe itching, and some patients have recurrent episodes, even in the teenage or adult stage. Due to repeated illnesses, it is easy to cause a vicious circle, which seriously affects the daily life and mental health of patients. The etiology of papular urticaria may be different for different people. It is necessary to ask the patient about the situation to determine the urticaria. Cause.
There are four main causes of papular urticaria. Please see the specific content:
1. Insect bites
Insect bites are still the main cause of disease Factors, almost all patients with papular urticaria have been bitten by insects before getting sick. This disease is an allergic reaction. Saliva and secretions after insect bites cause a series of allergic reactions, leading to this disease.
2. Infectious factors
Infectious factors are a pathogenic factor of papular urticaria. The results of related studies indicate that the disease is related to infectious factors, and infectious factors can induce or aggravate the disease.
3. Mental influence
Mental influence is also a pathogenic factor of papular urticaria, and there are related reports at home and abroad. Due to the influence of negative emotions such as tension, fear, and pressure, the body is in a state of tension for a long time, which causes a series of psychological and physiological reactions, namely stress reactions, leading to neuroendocrine disorders, and some physiological changes including enzymes, hormones, immune mechanisms, etc. The metabolic process causes this disease.
IV. Food allergy
Whether food allergy is a causative factor of papular urticaria has always been a matter of debate. Studies at home and abroad have shown that food allergy is a causative factor of this disease.
Three methods for the treatment of papular urticaria in children:
1. The treatment is mainly local symptomatic treatment. According to the appearance of the skin lesions, you can choose a lotion or emulsion with antipruritic and anti-inflammatory effects. paint on. If there is a secondary infection, it is advisable to control the infection first. If the symptoms are severe or the effect of topical medication is not good, systemic medication can be used. Generally, drugs with both antihistamine and sedative effects, such as diphenhydramine and chlorpheniramine, are used. Oral calcium lactate or calcium gluconate tablets have a certain effect.
2. Because the main cause of papular urticaria is insect bites, the key to prevention is to improve the environment, room, and personal hygiene to prevent the breeding of insects that cause this disease. Keep indoor air circulation, adequate ventilation and lighting, because mites are afraid of light, sun exposure can kill mites. Spray insecticides on beds, corners, furniture, etc. to eliminate bed bugs, fleas, and mosquitoesThere is a risk of transmission. Don't expose your skin to flowers and plants when you go out, especially young women and children.
3. People now only focus on symptomatic treatment in the treatment of papular urticaria in children, and not the allergic reaction itself: the immune response in the human body will reduce the number of TH1 cells, which are continuously produced under the stimulation of allergens. A variety of cytokines such as increased production of IgE and increased eosinophils promote the immune response to the TH2 pathway to form a humoral immune response. The supplementation of urticaria in children can participate in the regulation of immune cytokines and Xinminkang probiotics. This is a rare anti-allergic Active probiotics can promote the secretion of interferon in the body, regulate the TH1-type immune response and resist the immune globulin IgE, and regulate the TH2-type immune response that overreacts due to allergies by enhancing the TH1-type immune response of immune cells, which can enhance the anti-allergic ability of children . The intervention of Xinminkang probiotics anti-allergic immunity participating in regulation therapy can greatly reduce or shorten the course of anti-allergic western medicine, regulate immunity and reduce the occurrence of allergies.
Scientific care of papular urticaria in children:
1. The incidence of urticaria has a certain relationship with diet. Improper consumption may cause hives. For example, fish, shrimp, seafood, canned food, cured meats, beverages, etc. containing artificial coloring, preservatives, yeast and other artificial additives can induce urticaria. In addition, irritating foods such as too hot and sour will also reduce the digestive function of the gastrointestinal tract, causing food residues to stay in the intestines for too long, thus producing peptone and peptides, increasing the risk of human allergies.
2. Maintain an optimistic and peaceful attitude. Mood fluctuations can speed up the expansion of skin blood vessels and deepen the condition of urticaria, so maintain a calm mental state.
3. Life must be regular. Daily life should be regular, maintain scientific and reasonable living habits, and pay attention to the details of life.
4. Beware of allergies caused by drugs. In clinical practice, some drugs can cause urticaria
5, stay away from allergens and prevent harmful irritation. People with a history of urticaria should pay attention to keeping indoor and outdoor cleanliness and hygiene, and keep fewer pets such as cats and dogs at home. Avoid inhaling pollen, dust, etc., stay away from wind, cold, heat, dampness, fire, and insect poison. Rubber gloves, hair dyes, perfumed soaps and detergents, chemical fiber and woolen clothes, etc., may become undesirable irritation for people with allergies or urticaria and should be avoided.
