To the Editor:—
In the Nov. 5, 1960, issue of The Journal, page 1360, in the Correspondence Section, Dr. Rosenbaum of Cleveland Heights, Ohio, mentions the relief of annoying recurrent canker sores (aphthous stomatitis) which followed his avoidance of such foods as chocolates, potato chips, and salted nuts. Neither he nor the consultant, Dr. White, was able to account for the beneficial effect of the elimination of these foods from Dr. Rosenbaum's diet. Dr. White mentioned the frequently accused but unproven viral etiology, despite much recent evidence disproving this idea.We would like to call the attention of both these writers to our own studies, "Canker Sores from Allergy to Weak Organic Acids (Citric and Acetic)" (Tuft, L., and Ettelson, L. N.: J Allergy27:536-546 [Nov.] 1956) and "Buccal Mucosal Tests in Patients with Canker Sores (Aphthous Stomatitis)" (Tuft, L., and Girsh, L. S.: J Allergy29:502-510 [Nov.-Dec.]
