Abstract

There is no specific treatment therapy for silicosis so far, Silicosis continues to progress with silicosis patients resulting in impaired lung function, even though they had discontinued direct contact and exposure to silica dust. Silicosis patients are often hospitalized because of the disease's effects on the respiratory organs with symptoms that are not different from other common respiratory diseases. At National Lung Hospital, from June 2019 to May 2020, 103 silicosis patients qualified for this retrospective study which was conducted to identify the characteristics of data from their medical records. The results showed: 98% were male; most were workers from the non-structural sectors (gold miners 33.7%, stone miners 25.5%). Shortness of breath was the most common clinical symptom of the silicosis patients – 98.8%. Other clinical symptoms include: Alveolar murmur decreased -91.2%,  crepitant rale – 75.7%, and the moisture rale – 73.8%. In conclusion, this research shows that characteristics of silicosis patients had acquired the disease while employed at non-structural sectors.  It is necessary to exploit the occupational history to be able to diagnose silicosis early in the respiratory disease treatment facilities. Lifelong surveillance for the detection and management of silicosis patients should be carried out in accordance with industry guidelines. Therefore, it is recommended that employees presently employed at these non-structural sectors be required to be tested, and to be monitored regularly.
