Clinical manifestations of pneumoconiosis and pneumoconiosis

● What is pneumoconiosis? What are the legal pneumoconiosis in our country?

Pneumoconiosis is a systemic disease that is mainly caused by diffuse fibrosis in the lungs due to long-term inhalation of productive dust and retention in the lungs in occupational activities.

There are 13 types of legal pneumoconiosis listed in the list of occupational diseases regulated by the “Clinical Catalogue of Occupational Diseases” in China: silicosis, coal worker pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestos pneumoconiosis, talc pneumoconiosis, cement pneumoconiosis, mica pneumoconiosis, potter pneumoconiosis, and aluminum pneumoconiosis , Welder pneumoconiosis, caster pneumoconiosis, and other pneumoconiosis diagnosed according to "pneumoconiosis diagnostic criteria" and "pneumoconiosis pathological diagnostic criteria". Silicosis and coal workers’ pneumoconiosis are the most common pneumoconiosis in China.

● What are the most common types of pneumoconiosis in China?

The previous special occupational disease survey data and occupational disease report data released by the Ministry of Health for more than a decade have shown that silicosis and coal worker’s pneumoconiosis have been the most important pneumoconiosis in China, accounting for about 90% of the total number of reported pneumoconiosis cases.

● What are the clinical manifestations of pneumoconiosis patients?

The clinical manifestations of pneumoconiosis patients mainly include four symptoms: cough, expectoration, chest pain, and dyspnea. In addition, some patients may have wheezing, hemoptysis and some systemic symptoms.

Patients with early pneumoconiosis have no obvious cough, but as the disease progresses, cough can be significantly increased. Especially with chronic bronchitis or with lung infections, cough can be very serious. Cough in smoking patients is more pronounced than in non-smokers.

Pneumoconiosis patients may have cramps even when they have little cough. The pneumoconiosis patients in coal workers are mostly black, and coal dust particles can be clearly seen. If combined with pulmonary infection and chronic bronchitis, the amount of sputum is significantly increased, sputum yellow viscous or massive, and often not easy to cough.

Almost every patient with pneumoconiosis has light or heavy chest pain, which may be more common in patients with silicosis and asbestosis. The site of chest pain is not fixed, mostly limited; the nature of pain is not serious, usually hidden pain, pain, acupuncture-like pain.

Dyspnea is related to the severity of the condition. The occurrence of lung complications can significantly increase the degree of dyspnea and the speed of development, and can affect the heart, pulmonary heart disease.
