“…Chronic beryllium disease can look identical to sarcoidosis but has a history of exposure (often in the defence and aerospace industries). Hut lung (or domestically acquired particulate lung disease) is another interesting disorder that occurs in women exposed to dusts and fumes from cooking or burning dung or other fuels [ 32 ]. Fire eater's lung is another disease that has been associated with inhaling petroleum derivatives [ 1 ] and no doubt more diseases will be added to this list in the future.…”

The cystic lung diseases are rare orphan lung disorders that most physicians will see infrequently in their everyday practice. Diagnostic and treatment options have improved over recent decades, with opportunities for slowing rate of progression and improving outcome for patients. This review provides a summary of the clinical approach to these lung disorders, including how to differentiate between different imaging patterns, clinical features, differential diagnosis and characteristics of the commonest presenting disorders.Educational aimsTo understand the clinical, pathological and radiological features of cystic lung disordersTo explore the differential diagnosis of cystic lung diseaseTo be familiar with the key features (clinical, radiological, physiological and pathological) of the commoner cystic lung diseases, which assist in differentiating between these

“…Anthracosis is considered mild asymptomatic pneumoconiosis, suggested to be caused by exposure to biomass fuel and bronchial exposure to environmental particles (1). It can present as simple anthracosis with purely superficial black discoloration, complicated anthracosis with retracted mucosa and scattered foci of black spots, or severe bronchial anthracofibrosis (BAF) with severe submucosal edema, bronchial stenosis, and lung collapse (2).…”

Background: Anthracosis is a form of pneumoconiosis induced by frequent contact with smoke from biomass, air pollution, charcoal smoke, or dust particles. Objectives: This study aimed to investigate the association between anthracosis and pulmonary tuberculosis (TB). Methods: In this cross-sectional study, 401 patients undergoing bronchoscopy were recruited, and their demographic characteristics, clinical features, bronchoscopy and imaging results, pathologic-cytologic reports, and acid-fast bacilli (AFB) smear were recorded and analyzed. Results: The bronchoscopic results of 220 patients (54.9%) were normal, 93 (23.2%) had anthracosis, and 32 patients (8%) had anthracofibrosis. Positive pulmonary TB was significantly higher in patients with anthracosis or anthracofibrosis compared to those without (17.6% vs 4%; odds ratio (OR) = 5.09; P < 0.001). Patients with TB and anthracosis or anthracofibrosis had more prolonged contact with biomass (P = 0.002). Logistic regression showed age (P = 0.003) and the presence or absence of anthracosis or anthracofibrosis (P = 0.006) as associated factors with pulmonary TB. Conclusions: Anthracosis is associated with other pulmonary diseases, including TB; therefore, if anthracosis or anthracofibrosis is diagnosed, coincidental pulmonary TB should also be evaluated.

Biomass fuels (wood) are commonly used indoors in under-ventilated environments for cooking in the developing world, but the impact on lung physiology is poorly understood. Quantitative computed tomography (qCT) can provide sensitive metrics to compare the lungs of women cooking with wood vs. liquified petroleum gas (LPG). We prospectively assessed (qCT and spirometry) 23 primary female cooks (18 biomass, 5 LPG) with no history of cardiopulmonary disease in Thanjavur, India. CT was obtained at coached total lung capacity (TLC) and residual volume (RV). qCT assessment included texture-derived ground-glass-opacity (GGO: Adaptive Multiple Feature Method (AMFM)), air-trapping (expiratory voxels ≤-856HU) and image registration-based assessment (Disease Probability Measure (DPM)) of emphysema, functional small airways disease (%AirTrapDPM) and regional lung mechanics. Additionally, within-kitchen exposure assessments included particulate matter <2.5μm(PM2.5), black carbon, β-(1,3)-D-glucan (surrogate for fungi), and endotoxin. Air-trapping went undetected at RV via the threshold-based measure (voxels≤-856HU), possibly due to density shifts in the presence of inflammation. However, DPM, utilizing image-matching, demonstrated significant air-trapping in biomass vs. LPG cooks (p=0.049). A subset of biomass cooks (6/18), identified using k-means clustering, had markedly altered DPM-metrics: greater air-trapping (p<0.001); lower TLC-RV volume change (p<0.001), a lower mean anisotropic deformation index (ADI) (p<0.001) and elevated % GGO (p<0.02). Across all subjects, a texture measure of bronchovascular bundles was correlated to the log-transformed β-(1,3)-D-glucan concentration (p=0.026, R=0.46), and black carbon (p=0.04, R=0.44). This pilot study identified environmental links with qCT-based lung pathologies and a cluster of biomass cooks (33%) with significant small airways disease.
