Cold Atmospheric Plasma Device for Pediatric Molluscum and Verruca

The treatment device in this study generates cold atmospheric plasma. Cold atmospheric plasma has certain properties of plasma, such as ionized gas molecules. To create plasma, a pulse generator supplying 20 kilovolt pulse of 20-ns pulse width at 200 Hz (FPG10-01NM10, FID GmbH, Burbach, Germany) to a 5-mm diameter quartz-covered copper electrode of 10-cm length and 1 - 13mm quartz thickness. These nanosecond pulse parameters were chosen to provide sufficient treatment dose at the high level of plasma uniformity required to avoid any tissue damage. We will treat the lesions for approximately 1 to 2 minutes each, moving the electrode gently over the treatment area.

Cryotherapy refers to the application of liquid nitrogen using a cryospray device in order to freeze a lesion of interest. Treatment is repeated every few weeks until the lesion of interest has disappeared. It is considered SOC for the treatment of warts.

Chemical compound that acts as a vesicant to form a blister around treatment area. The blister lifts the lesion of interest away from the skin, causing it to slough off in a few days. It is used as SOC for the treatment of Molluscum Contagiosum.
