BACKGROUND: Chronic inflammatory states have been linked to the development of malignancy. Chronic rhinosinusitis (CRS) and allergic rhinitis (AR) have been associated with nasopharyngeal carcinoma (NPC) in population-based studies in Asia. A similar association with NPC and paranasal sinus malignancy (PSM) has not been defined in a North American population. Our purpose was to investigate the impact of CRS and AR on the risk of NPC and PSM. METHODS: The Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database was queried as a case-control study of adults ≥65 years of age...

OBJECTIVE: Although the benefit of surgical ablation for atrial fibrillation (AF) performed concomitant to mitral valve surgery is established, whether that performed concomitant to non-mitral cardiac surgery is beneficial remains unclear. In non-mitral, non-left-atriotomy cardiac surgery, the optimal surgical approach for AF remains to be established. Therefore, using the Japan Adult Cardiovascular Surgery Database (JACVSD), we compared 2 surgical ablation procedures [the maze procedure and pulmonary vein isolation (PVI)] performed concomitant to non-mitral cardiac surgery...
