Acne rosacea/demodex

1 post in this topic


I did a bit of online research last spring after someone here said his/her derm mentioned Demodex mites as a possible cause of his acneiform eruptions.

To show your hubby & make you feel better about those $100, here's a list of research papers I copied from a Rosacea site. The mites are implicated in the papulopustular form of Rosacea, the kind that looks very much like acne. The latest mite/Rosacea news is that the mites harbor a Gram negative bug of the bacillus genus (I've forgotten the exact name) that might be the actual irritant. The interesting thing about this is that the old sulfa drugs Bactrim and Septra, which many derms now consider the last resort/big guns before accutane, actually work best against Gram negative bugs.

I'll be reading your (and Queen's) journals with interest.
