Sir.—I just obtained the August 1986 issue of AJDC and noticed on the cover "Articles: Dysphagia Lusorum in Children." The word "lusorum" sounded strange. I turned to page 815 and tried to find out why lusorum was used, as all of my medical life (beginning as a medical student) I have been used to "lusoria." I did not find an explanation of the use of lusorum in the article, but the reference list referred to an article by Berenzweig et al entitled "Dysphagia Lusoria," so I looked in the BIG Webster's. "Lusorius" is an adjective, and there is nothing about "lusus" or lusorum (genitivus pluralis). The next source: Dorland's Illustrated Medical Dictionary. Here I found my memory confirmed: dysphagia lusoria. Lusus means play or game. This is correct, but dysphagia is not connected with lusorum. Therefore, dysphagia lusoria, but not "dysphagia of games."
