A child with psoriasis who could barely see the rash was admitted to the ward and came from thousands of miles away to see the doctor. The child had been sick for five years and had sought medical help everywhere, always hoping for a cure, and every time there was a rash the parents were worried. As a mother, I fully understand the parents’ feelings, but as a doctor, I must tell them: Firstly, psoriasis is a disease that cannot be cured so far. Secondly, the child is suffering from common psoriasis, which is the mildest type of psoriasis, affecting only the skin and not the internal organs. Third, based on the above two points, the goal of treatment is “control” rather than “cure”. If we seek to completely eliminate the rash, we will inevitably over-medicate the child and put a heavier burden on the child’s body and psyche than is warranted. Only when we set appropriate expectations can we achieve the best results with the least costly treatment, allowing our children to learn and live in the best condition. Fourth, do not believe in all kinds of “package cure”, “a shot of spiritual” and other false advertising, insist on going to the regular hospital. The medical development today, really can “cure” the disease few, so where is the value of medicine? The value of medicine is to control or alleviate the pain at minimal cost, so that people can live a relatively normal life. This is the art of treatment, but also the ultimate care for people.
