    As the world of podiatry becomes a larger and larger target for laser companies, what do you think would best prove the efficacy of using lasers to treat nail fungus?

    If a company were to put out a study that included the use of anti-fungal creams and sprays between treatment, do you believe it would discredit the study?

    Currently I have yet to see a very convincing study on this.

    I have no problem with industry done or funded research, as long as it stacks up to all the usual scrutiny (ie proper controls; blinding of subjects and assessors etc) and is published in a peer reviewed journal and all potential conflicts by authors are documented. For transparency purposes it is important that it was registered with one of the clinical trial registries.

    I regularly have a go at discrediting studies - who the authors are and who funded the study are usually near the bottom my list of things to be concerned about.

    You are right, there are yet no convicing studies on lasers and inychomycosis.

    Thanks for the input Craig. I completely agree with you. One of the problems I have had with a number of the studies that have been peer reviewed is that their treatment protocol included the use of topicals and sprays in between treatments. To me, within a study to prove the efficacy of lasers, there should only be the laser that is used to create a credible study.
  5. If I were designing a study to test the laser, I should want two identical "laser machines" one fitted with a laser diode emitting light within the "therapeutic range" and one fitted with a diode emitting an identical colour/ shape beam but at a frequency which has been shown to be inert to fungus (in-vitro, at least). I'd want patients randomly allocated and testers blinded , trial registered etc as Craig has already noted. No other treatment in between.

    Simon, much appreciated for your input as well. So you would like to focus on which laser wavelengths are actually able to eradicate fungus then? If that is the case, would you compare Q-Switched Nd:YAGs and long/short pulse Nd:YAGs, and diode lasers which are the available laser options right now. Or, would you also include other wavelengths including KTP, Alexandrite, Pulsed Dye or even ablative modalities as well?

    The reason I ask is that it is generally agreed that heat is needed in order to eradicate the fungus. And while it has not been scientifically proven it would be interesting to know whether any specific wavelength is actually attracted to the fungus itself.
  7. No, I would want to compare one which is thought to be efficacious with one which is known to be inert. Viz. a double blinded, placebo controlled trial. You would need to repeat for each of the available laser options which are claimed to be efficacious against an inert placebo that the patient nor practitioner cannot tell the difference between- hence a double blinded, placebo controlled trial. Once you've identified if/ which of them are better than placebo's, then you can start comparing them. But you need to show that they are better than placebo's on an individual basis first- unless your going to do a big, big, big study. I'm no expert on lasers, but I do understand research.

    That is a very interesting way to go about a study and one that has not been performed yet. All trials I have seen only rate the efficacy in terms of treatment with a specific model, as verified with KOH, PAS and/or cultures.

    Thank you so much for your insight on this!
