Silicosis

A 48-year-old man presents with a chronic cough and dyspnoea on exertion. He has worked in sandblasting for over 20 years and has had extensive exposure to silica dust. On examination, he has clubbing of the fingers and coarse crackles throughout both lung fields. His observations are: heart rate 85 bpm, respiratory rate 18 breaths per minute, blood pressure 125/80 mmHg, and oxygen saturation 94% on room air. Pulmonary function tests reveal a restrictive pattern.

Which of the following findings on imaging would support a diagnosis of silicosis?

A 52-year-old male quarry worker presents to the clinic with worsening dyspnoea and fatigue. He reports a history of extensive silica dust exposure. On examination, he has reduced breath sounds and fine crackles in both lung bases. His observations are: heart rate 92 bpm, respiratory rate 20 breaths per minute, blood pressure 130/85 mmHg, and oxygen saturation 93% on room air. A chest X-ray shows multiple small nodules and eggshell calcification of the hilar lymph nodes.

What is the most appropriate management strategy for this patient?

A 60-year-old man with a history of working in a foundry presents with worsening shortness of breath and a persistent dry cough. He has been diagnosed with silicosis, confirmed by chest imaging showing nodular opacities in the upper lung zones. He is concerned about the underlying mechanism of his disease.

Which of the following best describes the pathophysiology of silicosis?

A 60-year-old former sandblaster presents with chronic shortness of breath and a persistent cough. He was diagnosed with chronic silicosis several years ago and has recently noticed worsening symptoms. His oxygen saturation on room air is 88%, and a recent chest CT scan shows progressive fibrosis.

What is the most appropriate initial management strategy for this patient?

A 55-year-old man presents to the clinic with progressive shortness of breath and a chronic cough that has persisted for several years. He works as a stone mason and has a history of long-term exposure to silica dust. On examination, he has bibasilar crackles. His observations are: heart rate 88 bpm, respiratory rate 20 breaths per minute, blood pressure 130/80 mmHg, and oxygen saturation 96% on room air. A chest X-ray shows multiple small nodular opacities in the upper lung zones.
