矽肺病
Overview
矽肺病 is a lung disease caused by the inhalation of crystalline silica dust. Silica is a common mineral found naturally in sand and rock, such as granite and sandstone. Silica exposure is common in mines and quarries and in a number of other occupations such as construction (especially sandblasting), foundry-work, ceramics and glass-making. Silica scars lung and affects its ability to function normally.
Inhalation of crystalline silica particles may also lead to other conditions, particularly tuberculosis. There is also a link between silicosis and 肺癌.
Our Approach to 矽肺病
UCSF provides comprehensive evaluations and care for work-related lung diseases, such as silicosis. We offer a wide range of pulmonary function 测试s as well as flexible bronchoscopy to examine the airways.
Although silicosis currently has no cure, treatments can relieve 症状 and prevent complications. Lung transplantation may be an option for severe cases. UCSF is currently the top 肺移植 program in the U.S. for higher-than-expected patient survival rates and graft survival rates (ongoing function of the transplanted lungs).

迹象 & 症状
There are different types of silicosis depending on how quickly 症状 develop after exposure. The most common form is chronic silicosis, in which 症状 occur after 10 years or more of overexposure. The most common 症状 are chronic dry cough and shortness of breath with physical activity.
诊断
In making a diagnosis of silicosis, your doctor will start by taking a detailed medical and occupational history and conducting a thorough medical examination.
The following 测试s may also be conducted to make a definite diagnosis:
- 胸部x光片 A 胸部x光片 may be taken to look for any abnormalities in your lungs. In chronic silicosis, small round opaque areas appear on the lungs.
- Pulmonary Function Testing (PFT) 这 测试 involves a series of breathing maneuvers that measure the airflow and volume of air in your lungs, which allows your doctor to objectively assess the function of your lungs.
- 支气管镜检查 这 测试 involves passing a flexible fiberoptic scope, about the diameter of a pencil, into the lungs to obtain fluid and sometimes tissue samples to aid in diagnosis.
治疗
Unfortunately, there is no cure for silicosis. 然而, there is a variety of treatments available to help manage 症状 and prevent complications associated with the disease.
在严重的情况下， 肺移植 may be an option for some patients with silicosis.
