Rheumatologic diseases are a group of systemic diseases that affect multiple systems and organs, including systemic rheumatologic diseases, various types of arthritis, and many rare and uncommon diseases. Rheumatologic diseases are the most common type of difficult diseases in hospital internal medicine. Rheumatic immune diseases often lead to misdiagnosis and underdiagnosis, which should be brought to the attention of doctors and patients. First, pay attention to the systematic prevention and treatment of osteoarthritis. Osteoarthritis is a chronic, degenerative joint disease, mostly manifested as finger joints, knees, hips and cervical and lumbar spine joint pain, restricted movement and joint deformation. In China, there are currently about 30 million middle-aged and elderly people with osteoarthritis, which is almost equivalent to the population of two Beijing cities. This shows how important the prevention and treatment of osteoarthritis is. Second, understand the causes of osteoarthritis. The age of the population is aging, the prevalence of osteoarthritis increases significantly, and the older the age, the higher the incidence. the prevalence of people over 45 years old is about 10%, while the prevalence of people over 60 years old can be 40% to 60%. Weight factors are also closely related to weight, and the fatter a person is, the more likely he or she is to develop the disease. Weight factors certain occupational work and long-term joint weight imbalance may trigger osteoarthritis. Endocrine factors female menopause estrogen levels are reduced, is also an important factor leading to the occurrence of this disease. How to detect patients with osteoarthritis? 1.Educate and guide residents and patients to reduce weight to reduce the burden on joints. 2.Educate and guide patients to avoid excessive activities and joint loading. 3.Treatment needs to be individualized. At present, the main misunderstanding of domestic and foreign physicians about dry syndrome is that this disease is untreatable or does not need treatment. In fact, dry syndrome is not untreatable, and treatment by scientific methods can achieve long-term remission, prevent or reduce the involvement of liver, lung and kidney, and stop the occurrence of complications such as extra-glandular organs. However, due to sitting and waiting for the development of the disease for a long time, the condition of many patients becomes more and more serious, so that interstitial lung fibrosis, hyperglobulinemia, whole blood cell reduction and impaired liver and kidney function eventually appear. Therefore, doctors should correct the above misconceptions and provide active management and treatment for patients with dry syndrome.
