Area of Science:

Occupational Medicine
Pulmonary Medicine
Toxicology

Background:

Silicosis is a long-recognized occupational lung disease caused by inhaling crystalline silica dust.
Despite its known cause, worker exposure and disease outbreaks persist, indicating ongoing challenges in prevention.
Emerging and re-emerging exposure scenarios necessitate updated understanding and management strategies.

Purpose of the Study:

To review established and novel occupational silica exposures.
To describe the spectrum of silicosis, from acute to progressive forms.
To summarize known and potential health risks associated with silica exposure.

Main Methods:

Literature review of well-established and emerging silica exposure sources.
Review of imaging and histopathology findings for different silicosis classifications.
Synthesis of epidemiological data on silica-related diseases.

Main Results:

Identified new occupational risks including denim sandblasting and artificial stone cutting.
Detailed the pathological and radiological features of acute silicosis (silicoproteinosis), simple silicosis, and progressive massive fibrosis.
Summarized associations with tuberculosis, lung cancer, connective tissue diseases (e.g., systemic sclerosis), and vasculitis.

Conclusions:

Silica exposure continues to pose significant health risks in various occupational settings.
Understanding diverse exposure routes and disease manifestations is crucial for effective prevention and clinical management.
Further research into silica-related comorbidities and prevention strategies is warranted.
