Atopic dermatitis is a type of eczema. Unlike common eczema, atopic dermatitis has a genetic predisposition, so it is prone to recurrence and can be accompanied by asthma, allergic rhinitis and conjunctivitis when the baby is older. Usually atopic dermatitis can be divided into infantile, childhood and adult stages. The clinical manifestations in the infant stage are the same as those of ordinary eczema, except that it tends to occur more frequently in certain areas, such as the face and the extensor side of the limbs. The treatment principles for atopic dermatitis are the same as those for eczema, and appropriate hormone therapy is effective. It is worth mentioning that atopic dermatitis emphasizes skin care, and topical moisturizers and emollients are very important. 1, first of all, do the baby’s parents have allergies? For example, allergic rhinitis, asthma, skin eczema, hives, etc. If so, maybe the baby has hereditary allergic constitution. 2, I think the treatment can be appropriate topical hormones, such as Euthyrox, broken places with oozing can be topical anti-inflammatory drugs such as fusidic acid or Bactrim, while oral anti-allergy drugs, such as fenugreek syrup. 3, although hormones have side effects, but short-term use is not a big problem, hormone control of the disease can be used after non-hormonal drugs to maintain treatment. 4, skin care is vital, try to use less soap and body wash, do not take too many baths, the water temperature should not be too high, after bathing the whole body skin can use moisturizing cream such as urea cream or petroleum jelly, etc., to keep the skin moisturized. 5. Children with recurrent allergies can check allergens to find the cause, so as to avoid adding allergic foods when adding supplementary foods in the future, and to guide vaccination to reduce recurrence.
