hydrocortisone 0.5%, 1%, 2%
midrange potency topical corticosteroids:
betamethasone dipropionate, augmented 0.05%
High potency topical corticosteroids:
fluocinolone acetonide 0.2%
super-high potency topical corticosteroids
betamethasone dipropionate, augmented 0.05%, gel, ointment
1st gen antihistamines:
cross BBB readily, sedation and other anticholinergics effects: drying of secretions, visual changes, urinary retention
causative agent in non-bullous impetigo:
GABHS, Staph Aureus
mupirocin / Bactroban spectrum is:
select G+
common oral antibiotic for tx of MRSA cutaneous infection:
At what point can a child with impetigo return to school after beginning antimicrobials?
24 hours
peak in 2-5y/o; usually GABSA or Staph Aureus; localized; bullous type from S. Aureus; non-bullous type from Streptococcus; improve personal hygiene; mean duration 10d; tx for small topical area with mupirocin / Bactroban; tx for numerous lesions PO dicloxacillin, 1st or 2nd gen cephalosporin, azithromycin or clarithromycin (all are stable in presence of beta-lactamase; good against G+)
MRSA immune to % of mupirocin:
50% resistance
in case of erythromycin resistant strains of S. Aureus and S. pyogenies use:
HG TMP-SMX and clindamycin
Lithium contributes to:
acne vulgaris
acne lesions that respond best to topical antibiotics are:
inflammatory lesions
tx of rosacea:
metronidazole gel / MetroGel
best candidate for isotretinoin / Accutane:
cystic lesions who has used various therapies with little effect
follow which labs with isotretinoin use:
pregnancy status, hepatic enzymes, TG's
always ask about suicideality / depression change
acne vulgaris:
Propionibacterium acnes overgrowth leading to inflammatory reaction
tx of acne vulgaris, benzoyl peroxide:
benzoyl peroxide: low risk of skin irritation; agains P. acnes; usually with a topical antibiotic
tx of acne vulgaris with tretinoin / Retin-A:
increases epidermal cell turnover, transforms closed to open comedones; takes 6 weeks, photosensitizing
tx of acne vulgaris with oral abx:
clindamycin, erythromycin (macrolides), tetracycline (tetracyclines), azithromycin (, etc.; for moderate papular inflammatory acne; often needed long-term
tx of acne vulgaris with topical abx:
clindamycin, erythromycin, tetracycline; against P acnes, anti-inflammatory; for mild-moderate inflammatory acne vulgaris; less effective than oral abx
OCP use in tx of acne:
reduction in ovarian androgen production, decreased sebum production
tx of acne vulgaris with isotretinoin / Accutane:
inhibits sebaceous gland function, for tx of non-responsive CYSTIC acne; 4-6m; many SE's: cheilitis, conjunctivitis, hypertriglyceridemia, xerosis, photsenstiviity, TERATOGEN; women must use 2 birth control methods
SE's of isotretinoin / Accutane:
pseudo tumor cerebri. altered mood, suicideality, cheilitis, conjunctivitis, hypertriglyceridemia, xerosis, photsenstiviity, TERATOGEN; women must use 2 birth control methods

posterior torso % of skin surface:
anterior thigh % of skin surface:
palmar surface BSA measurement is approximately %?
traits of a burn that can be treated outpatient include:
