Psoriasis, commonly known as “psoriasis”, is a common and recurring chronic inflammatory skin disease. The lesions occur on the head, nails, extremities, umbilicus, and sacrum, with the knees and elbows occurring symmetrically. Local manifestations are dry erythematous patches with scales of varying sizes. At present, the prevalence in China is about 0.5%, with more than 6 million patients, and the incidence is on the rise. The incidence of the disease is mostly in young adults, with more men than women, more in the north than in the south, and more in urban than in rural areas. It is prone to recurrence and aggravation in winter. It is generally believed that psoriasis is a kind of skin cell hyperproliferative disease, the pathogenesis of which is not fully understood, and there are evidence of genetic factors, immune factors, infectious factors, psychological factors, bad habits and drugs. Clinically, psoriasis is divided into four types according to the severity of the disease: common type, pustular type, arthritic type and erythrodermic type. Psoriasis of the common type is the most common and the condition is mild. The various types of psoriasis can be transformed into each other and have a chronic process, and are prone to relapse after clinical cure. Although psoriasis does not directly affect life, it cannot be completely cured and has a long duration, but it has a direct impact on patients’ physical health and psychological health. In particular, the skin lesions are exposed and affect the aesthetics, often bringing a series of negative effects such as psychological and social. The pain it brings may be greater than some terminal diseases. Many patients are eager to cure it and bring more serious damage to themselves by blindly pursuing the efficacy of treatment. In the process of treating psoriasis we should avoid the following misconceptions: 1. Overburdened minds. Most psoriasis belongs to the common type, the symptoms are only rashes, which often get better in the summer, are not contagious and do not have much impact on health. Most patients have too much psychological pressure due to aesthetics and other reasons, which in turn aggravates the development of the disease. The actual fact is that you will be able to get a lot more than just a couple of days to get a lot more than just a couple of days. 2. Urgent and indiscriminate treatment. Psoriasis cannot be completely cured yet, and clinical treatment mainly focuses on controlling the disease, reducing symptoms and improving patients’ quality of life. With a long course and easy recurrence, patients are prone to anxiety, eager to seek medical help, blindly pursuing the effect of “cure” and resorting to irregular small clinics or certain so-called “recipes”. Many of these “prescriptions” are illegal and add hormones, anti-tumor drugs, immunosuppressants and other drugs, the short-term effect is often very good, the rash subsides significantly. But soon after discontinuing the drug, the condition worsens, and it is difficult to control the medication, triggering systemic damage and even transforming into a more serious erythrodermic psoriasis. 3. Irregular medication. Most of the psoriasis are of the common type, which only affects the local skin. Patients need to be treated under the guidance of a doctor, always choose the right drugs and dose according to the condition, and find a treatment plan suitable for the individual. Standardize the use of medication to minimize side effects. Topical medications such as carbotriol, tacrolimus, vitamin E cream, and various hormone creams are used when the rash is small, and topical black light irradiation is used when the lesion area is large. Systematic application of retinoic acid, immunosuppressants, histamine antagonists and other drugs can be used in case of systemic generalized rash. 4. Too fast for therapeutic effect. Psoriasis attacks have a great impact on the appearance and have a considerable psychological and emotional impact on patients, which makes many patients tend to pursue the recent curative effect, leading to indiscriminate medical treatment, drug abuse and pan-drug use. This will damage the long-term health of patients. The treatment of psoriasis is a long-term process that requires not only phased treatment of the acute phase but also long-term self-care in order to reduce recurrence and alleviate symptoms. Overall, most psoriasis is stable and leaves only a few skin symptoms, which can be treated with topical medication. Patients with psoriasis should learn about the condition and build up confidence; keep a relaxed mood, prevent sullenness and excessive tension, establish self-care awareness and improve lifestyle. Strengthen exercise and reduce upper respiratory tract infections; eat less beef, mutton and dog meat and quit smoking and drinking; pay attention to moisturizing the skin of the whole body, especially when entering the dry autumn and winter seasons; avoid excessive scratching of the skin and contact with irritating substances and drugs.
