Atopic dermatitis

Afodic dermafifis is also known as atopic dermatitis or atopic dermatitis. That is, a type of eczema is a chronic allergic skin disease with a family genetic tendency. Atopic dermatitis was first named in 1933 by Wise and Sulzberger. The term "ectopic" was first initiated by coca in 1925, and its meaning is: patients or family members are susceptible to a history of asthma, hay fever, allergic rhinitis, urticaria, eczema and other diseases; Protein hypersensitivity; lgE value in the patient's blood cyano increased; eosinophils in the patient's blood cyanocytosis increased. Atopic dermatitis is common in infants and adolescents and adolescents with an allergic constitution. It covers parts of the face, neck, elbows, knee sockets, and dorsal sides of the limbs. It shows symptoms such as rash, thickened skin, and rough skin. This disease recurs, and patients often suffer from scratches due to itching and intolerance, which not only hinders appearance, even causes sleep disturbance or affects outdoor sports and quality of life, and also adversely affects patients' psychology. Patients are often accompanied by bronchial asthma, allergic rhinitis, have a long course and are difficult to treat. They are regarded by the medical community as "the most difficult type of eczema". Both domestic and foreign reports indicate that the incidence of atopic dermatitis is increasing year by year. The incidence of industrialized developed countries is higher than that of developing countries. The incidence of atopic dermatitis is increasing year by year. The prevalence of children in industrially developed countries and regions is increasing. 20%, the prevalence in the United Kingdom has tripled in the past 50 years, and the United States has predicted that by 2009, the number of people with atopic dermatitis will reach 22 million. In China, the prevalence of atopic dermatitis from 6 to 20 years old is 0.7%, accounting for 30% of children who are treated in dermatology. The prevalence rate is 1.1% in cities and 0.73% in rural areas. The Institute of Dermatology of the Chinese Academy of Medical Sciences has investigated the incidence of atopic dermatitis in more than 10 large cities in China. The results show that the incidence of children aged 0-6 is 3%, and the number of affected people is 2.3 million to 3 million. This disease is becoming one of the main problems of public health. Until now, modern medicine has still used topical corticosteroids and emollients for the treatment of atopic dermatitis, but more and more evidence shows that the long-term efficacy of corticosteroids is uncertain, and side effects are difficult to avoid. With the rapid development of research and application of traditional Chinese medicine in recent years, the advantages of traditional Chinese medicine in treating atopic dermatitis with safety and effectiveness and few side effects have gradually become apparent.
