I'm glad you brought that up. I obviously hate fulgurations as much as the next guy, and the best career advice I ever received was from Rick Billingham, who said "Never give a talk on condyloma," as it's a surefire way to become the regional (or even worse, national) expert on the subject.
I do, however, want to dispel some myths about fulguration cases. I attached a nice review article on the subject that I think everyone should read. It's long, but the punchline is that
transmission via electrocautery has never been proven....
but transmission via laser plume has....so if your local OBGYN asks for the CO2 laser, start running.
Another article worth a look:
Transmission of HPV to gloves and masks
The other area of interest is the
special mask, which does much more to alleviate our fears than it does to actually prevent inhalation of toxic fumes. I was given some horrible news a year ago from my old PD: Because of the increased filtration, air will move preferentially around the N95 mask, entering your mouth through the sides....so unless you're going to have a complete seal (with duct tape on the corners), a regular mask may actually be beneficial. Personally, I feel like I'm suffocating with the N95 mask, so I'm sure I've left the ties a little loose in the past to make breathing easier.....
Of course, I had no data to back it up...until today. I did a short lit review, and found the following information:
1.
Masks aren't doing a good job, and most particles leak through the faceseal.
2.
Intensity of filter medium is not nearly as important as the fit of the mask, i.e. a well-fitting regular mask beats out a poorly-fitting special filtration mask.
3.
If you're really worried, it's best to take fast, shallow breaths.....
My personal approach is a normal mask (not N95 or other special masks), fit snugly, and regular old electrocautery with the student being Johnny-on-the-Spot with the suction. Another approach I frequently employ is to identify the case as a "resident case" and try to provide some "direct" supervision from the corner of the room.
