Psoriasis is a common chronic inflammatory skin disease. It is a polygenic disease that can be triggered by a variety of stimulating factors, such as trauma, infection, and medications, which may induce the disease in susceptible individuals. The onset of the disease is mainly in young and middle-aged people, and it has a greater impact on the physical health and mental condition of patients. So, how can psoriasis be treated? The following are the treatment methods for psoriasis, and precautions: 1. There are many treatment methods for psoriasis, which can be broadly divided into topical drug therapy, systemic drug therapy, phototherapy, surgical therapy, Chinese medicine, biofeedback therapy and so on. Topical drugs include local hormone creams, immunomodulators, retinoids, emollients, etc.; systemic drugs include antibiotics, retinoids, immunosuppressants, biological agents, etc.; phototherapy includes narrow-spectrum medium-wave ultraviolet light (NBUVB), PUVA, 304nm high-energy ultraviolet light, 308nm excimer light, 308nm excimer laser, etc.; Chinese medical methods include drug fumigation therapy, Chinese medicine bath therapy, Chinese medicine immunotherapy, Chinese medicine immunotherapy, etc. Chinese medicine medicine bath therapy, Chinese medicine immune balancing therapy, etc.; biofeedback therapy is one of the psychological adjustment therapy. 2.Which therapy has good effect in treating psoriasis? How long does it take? Individualized treatment is the guideline for doctors to choose the treatment plan, and doctors must take into account the patient’s condition, economic situation, distance, treatment time and other factors when formulating the treatment plan, for example, if there are only a few rashes, it is often possible to use only topical drugs, while those with large lesions need internal and external use + physical therapy or Chinese medicine. The distance is generally dominated by external oral therapy; when using phototherapy, those who are far away can choose a home type phototherapy device, those who are close can choose a medical type phototherapy device, those who have plenty of time can choose inpatient treatment, those who have a tight schedule can choose outpatient treatment. If a single treatment does not work, you can choose a combination of treatments. How to choose the treatment method requires the doctor’s experience and consideration of the patient’s condition. The treatment time varies from one area of the disease to another. If the psoriasis on the head and face is usually cured in 1 to 2 weeks, while the psoriasis on the trunk or extremities may take a month or more to heal. The current treatment technology cannot achieve the efficacy of “cure” or “never relapse”. Although it is not possible to “eradicate” the disease, many of them can be relapse-free for several years or more than ten years through reasonable prevention and scientific treatment by the patient. When there is no relapse, the skin around the body is the same as normal people, and no traces of the lesion can be seen in appearance. 3.How to screen the false advertisements of psoriasis treatment? 1) Sufferers should read more popular books or articles on psoriasis prevention and treatment written by dermatologists in regular hospitals to increase their clear understanding of the disease; 2) Some false advertisements often seize the eagerness to seek treatment and promote their own treatment to achieve “quick effect”, “root cause” and “never relapse”. “Some even claim to use “gene therapy” to treat the disease. (3) Some patients waiting for consultation in regular hospitals are often “brainwashed” by medical trustees dressed as “warm-hearted people” and go to those irregular medical institutions, and in the end, they are not well and spend a lot of money. Therefore, psoriasis patients should beware of medical trusts to avoid being cheated. 4.What are the things that female psoriasis sufferers need to pay attention to during their childbearing years? Avoid taking oral retinoids, immunosuppressants and other drugs that have an impact on fertility. 5.What drugs can induce or aggravate psoriasis? It has been shown that: 1) β-blockers: Takayasu (propranolol), apranolol, etc.; 2) non-steroidal anti-inflammatory drugs: including anandamide, pautazone, ibuprofen, diclofenac, etc.; 3) calcium antagonists (nifedipine, nimodipine, nicardipine), metformin, interferon-alpha; 4) hydroxychloroquine and lithium metal-containing drugs may induce and aggravate psoriasis.
