There is a folk saying in China that “external ringworm is not treated and internal asthma is not treated”, and this ringworm mainly refers to psoriasis, or psoriasis. Many patients are unclear about how psoriasis should be treated, and we find that less than 1/3 of them can achieve regular treatment, and more than 2/3 of them have improper treatment. There are several common phenomena in seeking treatment for psoriasis: 1. seeking treatment for a disease; 2. demanding too much from doctors; 3. being pessimistic and disappointed and not actively treating; 4. not being prepared for long-term treatment. Two examples are given. The first patient, after suffering from psoriasis, was so eager to seek treatment that he went to buy medicine to eat as long as there was an advertisement for psoriasis. The family took this medicine to the chemist. The family took the drug for laboratory tests, and it turned out to contain a large amount of ethosemicarbazone. Another patient, who had psoriasis all over his body after acute tonsillitis, came to the hospital and, based on his condition, analyzed that the onset of psoriasis was related to bacterial infection and gave him intravenous penicillin for two weeks. Three years have passed and there has been no recurrence. These are two very different examples, both with psoriasis, one cured and the other with leukemia. We did a study to compare psoriasis patients who had taken the “special drug” etidiumorphine with those who had not taken this drug, and the risk of leukemia was nine times higher for those who took etidiumorphine than for those who did not. Second, how to correctly treat and cure psoriasis? First, correct understanding and openness: psoriasis is a common skin disease, and according to the survey we organized in six provinces and cities nationwide, the prevalence of psoriasis in China is 0.59%, and it is estimated that there are nearly 8 million patients in China, which is a huge number. When you know you have 8 million sick people, you don’t have to cry out long and short and complain about God. Then again, although psoriasis is a chronic disease, but most of them only have rashes, 95% of them are common type, often improve or heal in summer, sometimes relapse or aggravate in winter, no contagious, and generally have no great impact on health. Therefore, patients must be educated to lift their worries, accept it openly with a calm mind, treat psoriasis as a “friend”, maintain an optimistic mindset, and establish the determination to fight the disease for a long time and the confidence to overcome it. In daily life, quit drinking and smoking, do not eat too spicy food, avoid stimulation of physical and chemical substances and drugs, and avoid upper respiratory tract infections. In the treatment, take the initiative to cooperate with the doctor. Second, formal treatment, no detours: What is formal treatment? It is to go to a regular hospital and specialist doctor, and to treat it clearly. Because the management system of China’s health care is not perfect, there are many irregular clinics, hospitals or individual practitioners in society, some of whom do not know anything about medicine, and some of them are greedy for quick results, but ignore the side effects of drugs, the application of many toxic side effects of drugs, many people who have been to these places have experienced, they either get a self-contained capsule, or herbs plus bags of medicine, it is difficult to know what is used It is difficult to know what kind of medicine is used. The problem often lies in these drugs, the first patient is due to the long-term use of drugs containing etidium morpholino led to the occurrence of leukemia, etidium morpholino can quickly control psoriasis, but because of its mutagenic effect on chromosomes, it is very harmful. The country has now banned the use of this drug. Psoriasis is not fatal, while leukemia can be fatal. There are many lessons learned in exchange for blood. Therefore, it is important to educate patients to try to visit a specialist in a regular hospital, and if possible, it is best to see one or several specialists on a regular basis. Doctors in regular hospitals may not necessarily make you well soon, but the treatment used by doctors must be clear, must be safe and relatively safe (generally doctors will explain and explain the side effects of drugs to patients, and often have appropriate preventive measures), is tested, and should be the best in terms of long-term efficacy. Third, scientific treatment and rational use of drugs: it is important to understand that 95% of psoriasis is the common type, which is a skin problem, and the internal organs are generally not involved. Doctors will consider the efficacy/risk ratio when deciding on the treatment plan, that is, to achieve the best efficacy with the simplest treatment and avoid side effects as much as possible. Patients should also follow the principles of scientific selection, small treatment for minor illnesses and major treatment for major illnesses, and actively cooperate with their doctors in their treatment. Clinically, topical medication alone is usually sufficient when the rash is small, and systemic medication is appropriate when the area is large. The most effective topical medications, such as cod liver oil ointment, vitamin E cream, various hormone creams (do not be afraid of hormones, as long as the medication is safe under the guidance of a doctor), carboplatin, Enlin, Tacrolimus, etc., are used well and the effect is very good. There is also ultraviolet therapy for larger areas. Systemic medications are antimicrobials (do not underestimate the effect of antimicrobials), retinoids and immunosuppressants. It is important to understand that all these treatments must be done under the supervision of a doctor. If you want to see a Chinese doctor, it is best to go to a regular Chinese hospital as well. Only rational and scientific treatment can ensure safe and effective treatment. Fourth, insist on treatment and scientific adjustment: Today is the era of information explosion, and almost every advancement in medicine is released online at the first time. There is a lot of information about the disease and many new drug information online, as well as many fish-eye advertisements. Many psoriasis patients like to catch up with the fashion, they often go online to inquire about new treatment methods, and once new methods appear, they hate to use them immediately, such as the recently appeared photon therapy, biological drug therapy and so on. It is important to know that any treatment has its strengths and weaknesses, and the latest is not necessarily the best. Therefore, once you have found out the treatment rules and effective drugs that suit you, try not to change them at will, and adjust them only when necessary. There are many psoriasis self-help treatment centers abroad, where doctors formulate a plan according to the specific conditions of the patients, and the patients themselves go to the treatment center to treat and manage themselves under the management and assistance of nurses, with good results. The treatment of psoriasis is often a long-term process, and some people hate all kinds of methods and drugs together when they relapse, hoping to be well tomorrow, while once controlled they are unwilling to maintain treatment again, making the disease relapse soon. In fact, in the treatment of psoriasis, it is better to choose the continuous therapy with a long flow of water rather than the “impact therapy” with a mountain of water. Generally, long-term treatment is combined with phased treatment, and internal and external use is combined. In this process, the communication and cooperation between doctor and patient is quite important. Psoriasis is a disease that affects the physical and mental health of patients, and it is understandable that patients are eager to seek treatment, but the treatment of any disease must be based on science, especially on safety. I hope the majority of patients remember the above advice, formal treatment, scientific treatment, persistent treatment, safe treatment, so as to obtain the best results.
