The state Medical Examining Board Tuesday ordered an employee of Laser55 of West Hartford to stop using an infrared laser device to heat fat tissue for potential weight loss, saying it constitutes the practice of medicine without a license. Though the board found that Pamela Borselle of Berlin is certified in using the device, it concluded she is not a doctor and she did not use the device under the direct supervision of a licensed physician. Borselle agreed to a cease and desist order to stop “the unlawful practice of medicine,’’ according to the order approved. At the same meeting, the board dropped charges against the owner of Laser55, Iyad “Edward” Shaham of West Hartford, because it found that only Borselle, and not Shaham, used the laser device on patients in 2012 and 2013. Laser55, at 836 Farmington Ave., advertises its services on its website as “Instant Weight Loss that Actually Works!” The medical board’s memorandum of decision states that the business uses the laser on localized areas of the body to warm fat cells under the skin by three to five degrees.
