All right. Let's do a couple quick questions
to review. Remember,
you can just pause the screen
after I ask the question,
then unpause it and we'll review the answer.
Okay. First up, all of the following are true
of psoriasis except?
Okay, number 1. Lesions often resolve
during the summer months.
That's true, even if we don't
fully understand why.
Number 2. Patients with HIV
have milder disease.
That is false. Patients with HIV can
often have debilitating psoriasis
and need more aggressive management.
Number 3, just to round things out,
may be exacerbated by smoking. That's true.
The inverse variant favors flexural creases.
That's true, as we've discussed.
Number 5, scraping off a plaque causes
pinpoint bleeding known as
Auspitz sign. That's a classic boards
question and it's definitely true.
So our answer is number 2.
And now for our second and final question.
The treatment of psoriasis
might include which of the following?
Okay. Oral minocycline. You might get
by with using it for acne rosacea,
but not for psoriasis. Ketoconazole lotion
would be good for tinea, not for psoriasis.
Topical benzoyl peroxide, you should certainly
think of that one with acne vulgaris.
Again, not for psoriasis. Topical tazarotene.
This is a topical retinoid,
which actually has been shown to
be effective for psoriasis.
And cryotherapy would be appropriate
for certain kinds of skin lesions,
but not psoriasis. So our answer, number 4,
and with that, we're done with psoriasis.
