The role of H. pylori infection in the patho- genesis of upper respiratory system diseases has been evaluated by some investigators.14 It is speculated that there is a relationship between GERD and chronic rhinopharyngitis and rhinosinusitis in both children and adult.15-17 It is suggested that direct reflux of gastric juice into nasopharynx may cause mucosal edema and inflammation, leading to obstruction of sinus ostia.18 Recently focus has been on the possible direct role of H. pylori in tissue injury of the sinonasal mucosa and development of chronic rhinosinusitis.4,6 However, the causality has not been estab- lished yet.	cache/eyereports-48.pdf	txt/eyereports-48.txt
