Dermatologist: Can psoriasis (psoriasis) be cured and what is the cause?

Psoriasis, commonly known as psoriasis, is a skin disease. Because psoriasis is commonly known as psoriasis, it is rightly thought to be contagious. It's actually an autoimmune disease, not a bacterial or viral infection, so it's not contagious. The following is a detailed description of the relevant knowledge of psoriasis. What is psoriasis is an environmental factor stimulation, polygenic genetic control, immune-mediated skin disease, so it is an autoimmune disease, is a chronic psoriatic skin disease. The typical presentation is psoriatic erythema or plaques, which can be localized or widespread throughout the body. Some also have joint symptoms or metabolic syndrome and other manifestations. The disease is protracted and prone to repeated attacks, which seriously affects the quality of life of patients. There is currently no cure, but the attack can be controlled. How is the prevalence of psoriasis? In European and American countries, the prevalence of psoriasis is 3% to 4%. The prevalence rate in my country is low, 0.47%. All age groups can be affected, and most people are younger than 40 years old. No gender differences. What are the types of psoriasis can be divided into four types according to clinical characteristics: vulgaris, arthropathy, pustular, erythrodermic. According to the site is divided into: scalp psoriasis, nail psoriasis, genital psoriasis. The etiology and incentives of psoriasis The etiology of psoriasis is unclear, and it is considered to be related to genetic and immune factors. The causes of psoriasis are bacterial and viral infections, such as recurrent strep throat, which may lead to a higher risk of psoriasis. Other triggers include stress, obesity, smoking, and drugs. Clinical manifestations of psoriasis Psoriasis can involve local or systemic skin, even joints, etc. Different clinical types have corresponding typical symptoms. Psoriasis vulgaris: is the most common type, accounting for more than 99%. Usually acute onset, the disease begins as a red papule or maculopapular rash, and then develops into a well-demarcated red plaque covered with white psoriasis. Scrape the wax drop, which is what characterizes the red patches plus silver flakes. After scraping off the silver flakes, you can see a reddish shiny translucent film below, and after peeling off the film, you can see tiny punctate bleeding spots, which is what the bottom layer of the skin lesion looks like. Lesions are commonly found on the elbows, knees, and sacrococcygeal regions, and are generally symmetrical. The skin lesions are itchy, burning and painful, and the skin is dry and can burst and bleed. Head psoriasis can appear as thick scales on the scalp. Joint psoriasis: In addition to skin lesions, it is accompanied by symptoms of small joints, such as joint swelling and pain, and severe joint deformities can also develop. Pustular psoriasis: In psoriasis vulgaris, dense, dense pustules the size of a miliary appear on the top of the skin lesions, and the pustules can also merge into a "lake of pus". Occurs on palms and fingers, soles and toes. Nails may have punctate depressions, transverse grooves, nail opacities and subungual empyema. This type may be accompanied by chills and high fever. Erythrodermic psoriasis: A very rare type. The skin of the whole body is red and swollen, and there are a lot of scales on the skin lesions, which may be accompanied by fever and swollen lymph nodes. How to treat psoriasis The purpose of treatment is to control the disease, delay the progression of the disease, relieve symptoms, prevent recurrence, and improve the quality of life. The individualized treatment plan will be selected according to the severity of the disease, the type of the disease, and the age. Treatment methods include: topical and oral drug therapy, physical therapy and traditional Chinese medicine. Topical drugs are mainly used, because external drugs directly act on the skin lesions, have the advantages of quick onset, convenient use, and few systemic side effects. Topical drugs include retinoic acid preparations, vitamin D3 derivatives, and glucocorticoids. Oral drugs are mainly immunosuppressive agents and biological agents. It should be noted that due to the characteristics of chronic and repeated attacks of psoriasis, the patient is very irritable and anxious, and the psychological pressure is high, which is not conducive to the improvement of the disease. Therefore, it is necessary to communicate with the patient and guide them to reduce the pressure and improve the quality of life. In conclusion, psoriasis is an autoimmune disease that is not contagious, and current treatments can control the disease, reduce flare-ups, and improve quality of life. In addition to drugs, psychological communication is also required during treatment to reduce the pressure of patients and improve the quality of life.
