Vinnie,
Hi, it is me again.
You may also contact Steve Fisher at Skin Cancer Center in Mera AZ 
(480-835-5532 tammysteve@cybetrails.com) for help.
Dr. Greg Bricca at John Vitelli MD Corp is preparing a publication on that 
issue and he may be able to offer some help.  Dr. Bricca's # is 412-681-9400.
Good luck
