The authors assessed the gene polymorphisms of missense C/T polymorphism in exon 6 of the urokinase-plasminogen activator (PLAU) gene (PLAU P141L), Alu-repeat in intron 8 of the tissue-type plasminogen activator (PLAT) gene (PLAT TPA25 Alu insertion), and 4G/5G in the promoter region of the serine proteinase inhibitor, clade E (SERPINE) or plasminogen activator inhibitor type 1 gene (SERPINE1 -675 4G/5G) in 153 healthy volunteers and 154 retired coal miners with coal miners' pneumoconiosis (CWP). The CWP subjects included 94 individuals with simple pneumoconiosis and 60 individuals with progressive massive fibrosis presenting with worse pulmonary function. The distributions of genotypes of these three genes did not differ between the control and CWP subjects or between subjects with simple pneumoconiosis and those with progressive massive fibrosis. However, by assessing duration of work and its interaction with genotypes by means of logistic regression, the authors found the missense C/T polymorphism in exon 6 of the PLAU gene to be an effect modifier of the association between work duration and the development of progressive massive fibrosis.

The incidence of empyema as a thoracic surgical site infection (SSI) is relating low, but empyema related to MRSA poses an unenviable therapeutic challenge. We review 3 cases of MRSA-related empyema as SSI seem in the last 10 years, and evaluate therapeutic measures. All 3 subjects began being administered vancomycin (VCM) systemically once the diagnosis was established. Subject 1 developed MRSA-related empyema following pulmonary segmentectomy for small-cell lung cancer. The subject was treated following a diagnosis of incisional SSI, with delayed adequate pleural drainage, resulting in treatment difficulties, but was cured without becoming MRSA-negative. Subject 2 developed MRSA-related empyema following pulmonary lobectomy for advanced lung cancer associated with pneumoconiosis. Following bronchoplasty, a chest tube was placed for long-term drainage. The subject did not become MRSA-negative after VCM administration, but became so after linezolid treatment, facilitating a cure. Subject 3, who had secondary pneumothorax, underwent thoracoscopic partial hepatic resection. Intraoperative findings suggested pleural cavity infection, necessitating a prophylactic drain, but MRSA-related pyothorax developed. Fibrinolysis with urokinase effectively cleared up the poor drainage and the subject was cured without becoming MRSA-negative. In conclusion, in controlling MRSA-related empyema as SSI noted that: (1) long-term postperative thoracic drain retention may lead to retrograde infection; (2) surgical procedures reducing the extent of pulmonary resection may effectively prevent pyothorax progression; (3) for poor drainage in advanced pyothorax, fibrinolytic therapy is worth attempting before thoracoscopic surgery; and (4) the timing for discontinuing anti-MRSA drugs should be determined based on the clinical course rather than negative conversion of bacteria.
