They need a new term -- "Vulna" is just too close in sound and in look to "vulva." Maybe it is on purpose to catch people's attention (it caught mine in a near spit-take), but that would be a poor decision for anyone who wants to be taken seriously.

Natural English here and didn't occur to me either.
