I thought I'd take a look at the patient.info front page to the LS discussions since I hadn't read it since last december 2017. At the time, they referred to the cause of LS as a "mystery" but thought it might have something to do with autoimmunity and hormones.
I see today August 21, 2018, that at some point the doctors involved with Patient.info have totally overhauled the page making it much more "user friendly" including a cute story by a journalist who tells of a woman who was cheerfully and easily aided by early detection and dermovate. Since there are no quotation marks I'm interpreting this as a made-up conversation for making the medical professionals diagnoses on here "palatable" to us idiots (warning that was cynicism).
Then down below that paragraph, there are comments from Dr. Emma Edmonds who went on to say that she does NOT think that LS is autoimmune. I looked her up online and find that she is a really brilliant dermatologist MD with her practice in the UK. I then dug further on her site to get to her biography. Yep, brilliant.. BUT... her work on thesis about LS was done in 1999. and something updated in 2005 I think.
SO; We can have brilliant doctors doing brilliant work and they still can barely keep up with the amount of research in whatever subject every single day.
I very politely sent her a message through her contact form with the link to the article i had found from the Journal of Investigative Dermatology: J Invest Dermatol. 2012 Mar;132(3 Pt 1):658-66. doi: 10.1038/jid.2011.369. Epub 2011 Nov 24.
asking her to consider this article and let us know or let the patient.info Docs know what she decides after seeing this 2012 journal article..
See how the front page is currently.....
