Although "Dermatology Times" carries no weight academically, it is still worth
taking a look at sometimes. I was pleased to see in the article titled
"Redefining rosacea: New options, new formulations, new classification system
mark advances" these two snippets:

* While rosacea was once considered to be one disease, a new algorithm divides
it into groups, or classifications, says Zoe Diana Draelos, M.D., a
dermatologist and researcher in High Point, N.C. *

* "We are learning that rosacea is probably multiple diseases with the same
presentation. Even though we do not have ways of predicting which medicines will
work best in which patients, we now have more treatment options, so that we can
customize treatment more for the specifics of the patient," Dr. Draelos tells
Dermatology Times. *

How many years have rosaceans been telling themselves, and their derms,
variations on the theme of "With so many different possible symptoms, surely
this isn't just one disease but a whole cluster?"
