Re:'Not Cryotherapy'

Having personally delivered a cryotherapy service in Primary care for
a number of years, I was amazed at the paper published. In my experience,
cryotherapy is both an effective and convenient method for treating warts,
veruccae and a variety of other minor skin lesions.
The methodology of this research is clearly flawed and I can only conclude
that the "dose" of cryotherapy, inadequate. In the past I have often come
across insufficient treatment intensity with cryotherapy by other
practitioners. This may lead to less inflammation or blistering, but is
much less effective than a more "robust" approach!
