Question 1: Why does my child have eczema. What is the cause and can I get to the root? A: The cause of eczema is complex. It can be caused by external factors, internal factors, or a combination of internal and external factors, and the cause is different for each individual. Although the cause of a particular child’s disease cannot be clearly identified, it is still important to try to find the causes that affect the onset of eczema. Once these factors are found, they can assist in our treatment. Question 2: Does every child with eczema need to be tested for allergens? How exactly? A: It is not necessary to check for allergens in every child. I suggest that those with more severe symptoms and a longer duration of illness should also be checked. By identifying the allergen, it can be a guide for treatment and care. Question 3: If the allergen test is positive, do I need to avoid eating? A: Not necessarily, it is a specific problem to be analyzed. Allergen testing can only be used as a reference. For example, if the milk allergy test is positive but there are no clinical symptoms, there is no need to abstain from eating. If there are obvious clinical symptoms, such as erythema, especially edematous erythema, then it should be avoided. In the case of a breastfed child, the mother should avoid foods containing milk proteins. Question 4: Can breast milk be allergic? Is there any alternative A: Breast milk itself is not allergic, and breastfeeding is promoted worldwide. Unless the above situation occurs, the mother needs to avoid foods containing milk proteins. There are three alternatives: fully hydrolyzed protein milk powder, deeply hydrolyzed protein milk powder, and soy milk. Question 5: Do I have to use hormonal creams? Will homemade ointments from the hospital work? A: Hormone-containing ointments should be used when available. Do not avoid hormonal topical medications. When the lesion is mild, non-hormonal creams can be used, especially in children over two years old, or when the lesion is on the face or near the external genitalia, non-hormonal creams can be considered. However, if non-hormonal creams are not effective, hormonal creams should be used. We recommend not to be overly superstitious about self-administered medication from hospitals. Especially when the lesion is more serious, the use of hospital self-administered medication is not recommended. Question 6: What is the dosage and course of treatment for topical medication? A: If the lesions are small, there is no need to consider the dosage. However, if the lesion area is large and hormonal creams are used, attention should be paid to controlling the dosage. In this case, you can refer to the knuckle unit, which is the length of the first knuckle of the index finger. 1 knuckle unit dosage can be applied to an area of two palms. If eczema recurs, it is recommended to extend the duration of the medication. It is recommended to use the full dose for two weeks, after which the dose is changed to once daily for another two weeks. If the lesions do not recur, the medication can be changed to 1 dose every other day for two weeks, and finally not discontinued, but maintained as 2 hormonal creams per week and non-hormonal creams the rest of the time.
