Paula Ray posted something about this topic in September - and we are still catching up! Just wanted to say that it seems to happen quite spontaneously and fairly infrequently. It can happen at any age. We have known this to happen in women aged in their teens (and have never had a pregnancy) and in elderly women long past menopause. The oldest woman we've heard of was in her early eighties!!! We know that we can get infections absolutely anywhere in the body without any particularly obvious reasons for that site to be a target, and we have simply felt that for similarly inscrutible reasons these infections are in this category - you could say that our immune defences may just have collapsed at what was momentarily the weakest point. Did anyone else have further input on this? Robyn Noble and Anne Bovey, Brisbane, Australia
