Case: The baby is three years old and some time ago red spots with scales suddenly appeared on his body. She went to the local hospital for examination and was diagnosed with psoriasis. The child was prescribed some topical ointment, but after using it for a period of time, she did not see any improvement. Instead, from a few spots on her legs and arms at the beginning, they have now developed into spots all over her body, and some of them have already become flaky. What should I do? The initial judgment is that it belongs to progressive psoriasis. The factors that contribute to the development of psoriasis are complex and are generally considered to be related to a variety of factors. The actual fact is that you can find a lot of people who have been in the business for a long time. Genetic factors: Children with psoriasis inherit the susceptibility gene for psoriasis, so this group of people are more likely to develop psoriasis than normal people when they encounter external triggers. After a lot of clinical practice experience, our hereditary odds have a family history of 32%, and its mode of inheritance is autosomal dominant, and its epigenetic rate accounts for 20%. If one of the parents has the disease, the chance of inheritance is about 18%. Improper diet: Allergies due to diet or medication, or exposure to a substance, can often trigger psoriasis. After each relapse, patients need to carefully recall what they have taken recently or have been exposed to a certain substance, which makes the skin itchy and then red spots appear, then this substance, in the future, should try to avoid contact, for example, certain seafood, beef and mutton, spicy things and other substances. At present, it is recommended to stop using medication. The physical condition of children is relatively weaker than that of adults, and some hormonal drugs will bring more serious effects to children, and it is better to go to a regular specialized hospital for a comprehensive examination to determine the cause of the disease and prescribe the right medicine.
