Benign, atraumatic, bronchoesophageal fistulae.

We report two patients with bronchoesophageal fistulae resulting from benign causes. The first resulted from erosion of an acquired middle esophageal diverticulum. The second had the prolonged clinical course of a presumed congenital fistula. The importance of barium examinations in evaluating chronic respiratory complaints is emphasized.

Salicylate effects on proton gradient dissipation by isolated gastric mucosal surface cells.

The effects of salicylate were examined on Na+/H+ exchange by isolated gastric mucosal surface cells loaded with H+ and resuspended in a buffered medium. Choline salicylate (pH 7.4) increases the dissipation of an intracellular proton gradient which was measured using acridine orange. The exchange of extracellular Na+ with intracellular H+ by surface cells not only remains intact but also is enhanced upon exposure to salicylate. This was confirmed by cellular uptake of 22Na and titration of cellular H+ efflux. Salicylate increases Na+/H+ exchange via a pathway predominantly sensitive to amiloride. However, the data also suggest that salicylate dissipates an intracellular proton gradient by an additional mechanism. The latter is independent of extracellular Na+ and not due to a generalized increase in cellular permeability.
