Psoriasis is a chronic inflammatory skin disease induced by multiple factors and inherited by multiple genes, with a global prevalence of about 1-2% and a prevalence of about 0.47% in China. A survey conducted by the Institute of Dermatology of the Chinese Academy of Medical Sciences on 320 cases of psoriasis patients found that: 58.6% of patients did not know about psoriasis; only 8.6% of patients had consulted doctors; more than 89% of patients had never been exposed to psoriasis science and technology; 24% of patients mistakenly believed that psoriasis could be cured; 65.7% of patients had received treatment from “traveling doctors”. Family history, infection, humidity, smoking, alcohol consumption, mental stress and trauma are risk factors for the development of psoriasis. Most psoriasis patients have moderate or higher anxiety and depression, and the care of family and friends is a good medicine for patients. Pregnancy in female patients with psoriasis vulgaris does not have significant adverse consequences for the fetus, and the condition remits or disappears during pregnancy, and it is extremely rare for the condition to worsen. Patients with psoriasis in the acute stage should avoid the external use of irritating drugs, scratching or improper stimulation, and be alert to the fact that some oral drugs such as corticosteroids, tetracycline, antimalarials, anti-inflammatory pain, acetylsalicylic acid, etc. can aggravate the disease. Psoriasis not only has skin damage, but also complicates cardiovascular disease, depression and osteoporosis, which can reduce the quality of life and shorten the life expectancy of patients. However, psoriasis is not contagious, so patients must actively treat it and adhere to consolidation treatment after the condition has improved. The treatment of psoriasis needs to be comprehensive and individualized, and the options are topical treatment (carbotriol, etc.), systemic treatment, phototherapy, traditional Chinese medicine, biological agents, etc. You should not seek treatment in a hurry or “over-treat”, but consult a dermatologist at a regular hospital before choosing a specific treatment method. World Psoriasis Day is celebrated on October 29 every year. Psoriasis is not terrible, and the correct understanding and treatment of psoriasis will definitely help psoriasis patients regain their confidence in life and work.
