Papular urticaria is a common allergic skin disease in infants and young children. When the temperature is high in summer, many insects become active, and children with allergic predispositions may become ill. Papular urticaria often occurs on the trunk and extensor sides of the limbs, but is less likely to affect the head and face. Skin lesions appear as wheal papules or wheal blisters. Most children suffer from severe itching, especially at night, which often affects sleep and makes children restless.

Papular urticaria is also called urticarial lichen and infantile lichen. It is a common allergic skin disease in infants and children, but adults can also suffer from it. Often several people in the same family get sick at the same time. It occurs more often in spring and autumn. This disease is named after the characteristics of its symptoms. In fact, this disease is insect bite dermatitis. The clinical characteristics are scattered, slightly hard papules with vesicles at the top. There is spindle-shaped redness around the edges and itching occurs consciously.

Papular urticaria is a skin disease that commonly occurs in children. The cause and pathogenic factors are unknown. It is accompanied by severe itching. In some patients, the condition relapses and even continues into adolescence or adulthood. Due to the recurrence of the condition, it is easy to cause a vicious cycle, which seriously affects the patient's daily life and mental health. The causes of papular urticaria may be different for different people. The cause of urticaria can only be determined by asking the patient in detail. Cause.

There are four main causes of papular urticaria, please see the specific content:

1. Insect bites

Insect bites are still the main factor in the disease. , Almost all patients with papular urticaria have been bitten by insects before getting sick. This disease is an allergic reaction. The saliva and secretions after insect bites cause a series of allergic reactions, leading to this disease.

2. Infectious factors

Infectious factors are a cause of papular urticaria. Relevant research results show that this disease is related to infectious factors, which can induce or aggravate the disease.

3. Mental influence

Psychological influence is also a factor in the pathogenesis of papular urticaria, and there are relevant reports at home and abroad. Due to the influence of tension, fear, pressure and other negative emotions, 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. Metabolic processes cause this disease.

4. Food allergy

Whether food allergy is the cause of papular urticaria has always been a matter of debate. Domestic and foreign studies have shown that food allergy is a cause of this disease. .

Three methods for treating papular urticaria in children:

1. Treatment is mainly local symptomatic treatment. Depending on the performance of the skin lesions, you can choose lotions or lotions with anti-itching and anti-inflammatory effects. Apply the emulsion externally. If there is a secondary infection, it is better to control the infection first. If the symptoms are severe or local medication is not effective, systemic medication can be used. Generally, drugs with both antihistamine and sedative effects are used, such as diphenhydramine, chlorpheniramine, etc. Oral calcium lactate or calcium gluconate tablets have certain effects.

2. Because the main cause of papular urticaria is insect bites, the key to prevention is to improve the environment, home and personal hygiene to prevent the breeding of insects that cause this disease. Maintain indoor air circulation and provide adequate ventilation and lighting, because mites are afraid of light and sun exposure can kill mites. Insecticides can be sprayed on beds, corners, furniture, etc. to eliminate the risk of spreading bedbugs, fleas, mosquitoes, etc. Don't expose your skin to flowers and plants easily when going out, especially young women and children.

3. People now only focus on the treatment of symptoms of papular urticaria in children, and not on the allergic reaction itself: the immune response in the human body will reduce the number of TH1 cells, and when stimulated by allergens, The continuous production of a variety of cytokines such as the increase in the production of IgE and the increase in eosinophils prompts the immune response to move towards the TH2 pathway to form a humoral immune response. Children with urticaria often supplement Xinminkang probiotics, which can participate in the regulation of immune cytokines. This is a rare The anti-allergic active probiotics can promote the secretion of interferons in the body, regulate the TH1 immune response and resist immunoglobulin IgE. By promoting the TH1 immune response of immune cells, it can regulate the TH2 immune response caused by overreaction due to allergies, and can improve children's anti-allergic response. Allergy Ability. The intervention of Xinminkang probiotic anti-allergic immune intervention therapy can greatly reduce or shorten the course of anti-allergic western medicine, regulate immunity and reduce the occurrence of allergies.

Scientific nursing care for children with papular urticaria:

1. The onset of urticaria has a certain relationship with diet. Improper consumption may cause hives. For example, fish, shrimp, seafood, canned foods, pickled foods, and drinks containing artificial colorings, preservatives, yeast and other artificial additives can all induce urticaria. In addition, irritating foods such as too sour and spicy 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 chance of human allergies.

2. Maintain an optimistic and peaceful attitude. Mood fluctuations can accelerate the expansion of blood vessels in the skin and worsen the condition of urticaria, so you should maintain a peaceful mental state.

3. Life must be regular. Your 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 stimulation. People with a history of urticaria should pay attention to keeping indoors and outdoors clean and hygienic, and keep fewer pets such as cats and dogs at home. Avoid inhaling pollen, dust, etc., and stay away from wind, cold, heat, dampness, dryness, fire, insect poison, etc. Rubber gloves, hair dyes, perfumed soaps and detergents, chemical fiber and woolen clothing, etc., may be harmful irritants to people with allergies or those suffering from urticaria and should be avoided.
