Eczema (atopic dermatitis) has some very common “aliases” and you may be told by your doctor that you are “allergic, dermatitis, ringworm”, etc. Some of these diagnoses are correct, while others are misdiagnosed, such as treating eczema as “ringworm Some of these diagnoses are correct, but others are misdiagnoses, such as treating eczema as “ringworm. Strictly eczema (atopic dermatitis) has the following characteristics: it is a chronic inflammatory skin disease associated with genetic allergic qualities, manifested by itching, polymorphic lesions with exudation, often accompanied by asthma, allergic rhinitis . The term “atopy” itself means: ① a family tendency to develop asthma, allergic rhinitis, and eczema; ② allergy to xenogeneic proteins; ③ elevated serum IgE levels; and ④ peripheral blood eosinophilia. To parents who come to the clinic, I often ask: do the parents of the child have dry skin, allergic rhinitis, asthma, etc., and whether the adults have frequent itching of the skin, which means that “most allergic diseases have a history of heritage, and the child’s bad skin is not unrelated to “you”. Because of the genetic factors involved, the goal of eczema treatment is to control and delay recurrence without affecting the quality of life. The different stages of eczema (atopic dermatitis) have different characteristics, and sometimes the different stages of lesions can overlap. Typical examples are as follows: Infancy Approximately 60% of patients develop the disease within one year of age. The initial lesions are usually erythematous on the cheeks and face, followed by the appearance of pinpoint papules and papules on top of the erythematous base, which are dense and indistinctly bounded. The lesions can be severe and can be combined with bacterial and viral infections. The lesions can rapidly expand to other areas. The lesions may spread rapidly to other parts of the body. The disease usually improves gradually within 2 years of age, but some patients may develop AD in childhood. The immediate manifestation is redness, small bumps, and severe watering. The lesions involve the flexors or extensors of the extremities, often limited to the elbow fossa and coy fossa, followed by the eye, face and neck. The lesions are dark red and exude less than in infancy. Typically, rough erythema and papules appear at the bend of the elbow and knee, which are not smooth to the touch, commonly known as “four bends of wind” in Chinese medicine. Young adult stage refers to the adolescent and adult stages of AD after the age of 12. There are several critical periods when your child may experience significant remission or relapse, such as around 2 years old and after preschool. Above treatment, pay attention to the discovery of environmental factors that may aggravate the condition (such as scratching, irritating food, etc.) and try to avoid them; appropriately reduce the number of baths and the use of soap to avoid excessive removal of sebaceous film, while topical moisturizers can be used . 1, the principle of topical drug treatment and eczema is the same. Glucocorticoid is the main drug to control the condition and relieve the symptoms. Moisturizers can ease dry skin. In recent years, the topical use of calcium phosphatase inhibitors (such as tacrolimus and oral bimatoprost ointment) for the treatment of this disease, to achieve better results. 2, systemic drug therapy oral anti-histone drugs can varying degrees to relieve itching and reduce scratching, secondary to bacterial infections need to add antibiotics. To sum up, avoiding suspected causative factors, checking allergens and such in children with recurrent severe time, moisturizing dry skin, proper and reasonable use of hormones as well as combining with non-hormonal topical application, preventing infection, controlling itching and restoring the normal function of skin barrier. This needs to be done by parents, children and doctors together.
