To the Editor.—
Referring to the letter "Photo-Onycholysis Secondary to Psoralen Use" in the March 1978 Archives (114:448), we would like to inform Dr Rau and associates that our detailed article on this subject was published in May 1977.1As a matter of interest, most European dermatology journals preferentially print articles that are submitted in English, since expansive perusal is anticipated.
