As a group, SSBE patients have more competent LES sphincters and less gastroesophageal reflux at 0 and 5 cm above the LES as compared with patients with LSBE. These data indicate that the degree and length of acid exposure in the esophagus are important factors in the pathogenesis of SIM involvement of the esophagus.

The spirometric interpretations of a group of general internists differed significantly from those of two board-certified pulmonologists using published guidelines in approximately one third of cases. This may be because subspecialty guidelines are infrequently published in the general internal medicine literature. We believe that wider dissemination of these interpretative guidelines and ongoing physician education would improve general internists' ability to identify patients who require further pulmonary evaluation.
