Infectious papillomavirus in the vapor of warts treated with carbon dioxide laser or electrocoagulation: Detection and protection

摘要: Papillomavirus DNA has been reported recently in the vapor (smoke plume) derived from warts treated with carbon dioxide laser; this raises concerns for operator safety. We therefore have studied a group of human and bovine to define further potential risk wart therapy test whether surgical mask could reduce exposure. Half each was laser other half electrocoagulation. The produced by form collected dry filter vacuum apparatus analyzed presence papillomavirus. Vapor plantar papillomavirus DNA, because there is no infectivity assay Of treated, five eight laser-derived vapors four seven electrocoagulation-derived were positive DNA. Greater amounts usually recovered than electrocoagulation same wart. Bioassay readily detected infectious either modality; more virus present material. A found capable removing virtually all laser- or virus, strongly suggesting that such masks can protect operators inhalation exposure
