Brief summary
To evaluate the safety and efficacy of the PathoLase FootLaser treatment of infected toenails.
Detailed description
The study is a multi-center controlled study evaluating laser treatments of infected great toes in a randomized blinded study of approximately 125 subjects. Right and left great toes are randomized to treatment or no treatment. Samples from infected areas are sampled and evaluated for presence of fungus with KOH, PCR and culture tests. Nail bed clearing and nail plate growth are measured from high resolution photographs by a blinded evaluator. Subjects will be evaluated at baseline and at 8, 16, 24 and 48 weeks for safety and effectiveness of study treatment.

Outcome results
Nail Bed Clearing
Change in amount of clear nail over time.
Time frame: 48 weeks
Population: There was a fatal design flaw to the trial. We were advised to collect nail samples for mycologic analysis at every visit. As a result investigators were removing our primary outcome variable, increase in clear nail, at each visit. Consequently our estimates of nail growth following treatment are inaccurate and invalid.
Mycology
KOH, PCR and cultures of patients who were bilaterally positive or negative for each test.
