Study of clinico-radiological profiles of patients with occupational interstitial lung disease in a tertiary care center

Sir, Interstitial lung diseases (ILDs) constitute a diverse group of pulmonary disorders classified together because of similar clinical, roentgenographic, physiologic, or pathologic features. OILD was due to asbestos exposure in 13, silica in 7, iron dust in 5, 2 due to rubber, 2 because of junk cleaning (exposed to hydrogen sulfide), and the remaining 6 had ceramic, glass, amoxicillin production, steel polish, balloon blowing, and welding exposure each [Figure 1]. {Figure 1} The various NOILDs diagnosed were idiopathic pulmonary fibrosis (9), sarcoidosis (8), nonspecific interstitial pneumonia (7), hypersensitivity pneumonitis (5), systemic sclerosis (3), 1 each of rheumatoid arthritis (RA-ILD), Churg–Strauss syndrome, and combined pulmonary fibrosis and emphysema.
