Recruitment Patients ostensibly meeting the study inclusion and exclusion criteria seen in an outpatient setting by the authors and their associates and staff will be apprised of the availability of a research treatment for fungal toenail infection. The study will be briefly described - patients who express an interest will be provided additional information and a study consent form and be encouraged to ask questions about the study. They may choose to provide consent at the time or to leave with the consent form and return at a later time to ask further questions.
