ABSTRACT
OBJECTIVE: To analyze the clinical characteristics of occupational aluminum pneumoconiosis caused by aluminum fluoride dust. METHODS: The clinical data of a case of occupational aluminum pneumoconiosis caused by occupational exposure to aluminum fluoride dust was retrospectively analyzed. RESULTS: The patient had a clear history of occupational exposure to aluminum fluoride dust for 13 years. The main clinical symptoms were chest tightness, cough and expectoration. High kV posterior and anterior chest X-ray showed that the texture of both lungs was increased and blurred, and multiple small dot-shaped shadows, including round or q-shaped shadows, were seen in the both lung fields and distributed in 6 lung regions. Chest computed tomography showed that the texture of both lungs increased, and multiple small punctate high density lesions were found in both lungs. The pulmonary function examination showed the small airway ventilation dysfunction and the gas diffusion function was reduced. It was diagnosed as occupational aluminum pneumoconiosis stage Ⅱ. CONCLUSION: Aluminum fluoride-induced occupational pneumoconiosis has slow onset and lacks specificity in clinical symptoms. The chest X-ray manifestations are mainly increased pulmonary texture and small round shadows.
ABSTRACT
Objective@#Select the appropriate disease assessment indicators, formulate the comprehensive evaluation group of pneumoconiosis patients, and explore the role of the comprehensive evaluation grouping in the clinical evaluation of pneumoconiosis, and provide the basis for the prognosis of pneumoconiosis.@*Methods@#Combined with clinical symptoms, pulmonary function, pneumoconiosis stage, acute exacerbation and complications, a comprehensive assessment of pneumoconiosis patients was established.138 newly diagnosed pneumoconiosis patients were divided into low risk group, middle risk group and (very) high risk group. The patients were followed up by telephone to record their health status and quality of life within one year after discharge from hospital. Analysis of the relationship between the comprehensive assessment group of patients with pneumoconiosis and symptom score, pulmonary function, pneumoconiosis stage, acute exacerbation and complications. The relationship between the comprehensive assessment group of pneumoconiosis patients and the risk events (the number of visits, hospitalization, mechanical ventilation, death cases in one year) and CAT score were analyzed.@*Results@#There were significant differences in clinical symptoms, pulmonary function injury, pneumoconiosis stage, acute exacerbation and complications among patients in low risk group, middle risk group and (very) high risk group (P<0.01) . With the increase of comprehensive assessment score, CAT score increased, the risk events increased, the difference was statistically significant (P<0.01) . Spearman correlation analysis showed that the comprehensive assessment group was significantly correlated with the number of visits, hospitalization, mechanical ventilation, deaths and CAT score in one year.@*Conclusion@#Combined with clinical symptom assessment, pulmonary function assessment, chest imaging assessment, acute exacerbation assessment, and complication assessment, the pneumoconiosis patients' comprehensive assessment group formulated can evaluate the severity of pneumoconiosis patients, and make a more accurate and comprehensive judgement of the disease.
