teratogen, hepatotoxicity, hypertriglyceridemia, pancreatitis, suicidal ideation
2
adverse effect of combining oral isoretinoin with tetracycline
pseudotumor cerebri
3
treatment for necrotizing fascitis caused by streptococcus or clostridia
penicillin G +/- clindamycin
4
general empiric treatment of necrotizing fascitis
impinem +/- vancomycin
5
treatment for MRSA skin infections

minocyclin + rifampin
linezolid $$$
6

facial erythema with telangiectasias starting at the nose and cheeks
provoked by various stimuli including spicy foods
rhinophyma (sebaceous gland hyperplasia of the nose)
7
treatment for rosacea

sulfacetamide + sulfur
metro-gel, metronidazole
rhinophyma may require laser therapy

tetracycline, doxycycline, or accutane
8
when antibiotics should be used in the treatment of skin abscesses
if abscess is > 5cm or if patient has comorbidities: diabetes, immunocompromised
9
preferred medication in treatment of scabies
permethrin soap
second line: oral ivermectin
10
characteristic features of necrotizing fasciitis
necrosis, purple, woody texture, crepitus, pain extends beyond region of cellulitis
11
treatment for dry gangrene
auto-amputation
12
treatment for wet gangrene
debridement or amputation
13
medication options for treatment of acne vulgaris
first line: topical retinoin
second line: oral/topical antibiotic or benzoyl peroxide
other options: OCPs, spironolactone, or oral isoretinoin for cystic acne
14
time-frame in treatment of varicella
antivirals if within 72 hours
15
side-effects from oral isoretinoin
hepatotoxicitiy, suicidal ideation, teratogenic effects, elevated triglycerides and pancreatitis
16
appearance of molluscum contagiosum
painless shiny papules with central umbilication
17
treatment for molluscum contagiosum
self-limited, most resolve within 3 years
chemical, laser, or cryotherapy for removal
imiquimod will induce inflammatory reaction against lesion
18
treatment for tinea capitis
oral griseofulvin, terbinafine
topical will not work because the tinea is INSIDE the hair follicle
19
lichen planus features
pruritis, purple, polygonal, papules, and plaques
shiny and flat on flexor surfaces
associated with HIV and hepatitis C
20
treatment of lichen planus
topical or intralesional medium to high-potency steroids
acitretin (oral retinoid)
21
stages of decubitous ulcers
stage I: pressure related alteration in intact skin such as change in color, consistency, or temperature
stage II: superficial ulcer, abrasion, or shallow crater
stage III: full thickness skin loss
stage IV: extensive destruction or necrosis, damgage to muscle or bone
22
treatment of decubitous ulcers
address nutrition to help body heal
relieve pressure, soft mattress, elevate heels
debride if necessary with hydrocolloid dressing
23
stasis dermatitis
caused by vascular insufficiency
increased pigmentation, scaly and crusted erosions, ulcers
treat with compressive stockings, elevation of legs, topical steroids, consider horse chestnut seed extract, aspirin to accelerate healing of ulcers
24
medications that cause erythema multiforme
penicillins, sulfonamides, NSAIDs, OCPs, anti-convulsants
25
distinctions between erythema multiforme, stevens-johnson, and TEN
erythema multiforme: target lesions, no sloughing of skin
stevens-johnson: 30% body sloughing, decreased WBC, decreased H/H, elevated LFTs
26
classic presentation of pityriasis rosea
herald patch followed by christmas tree rash 1-2 weeks later
27
treatment for pityriasis rosea
self-limited, consider UV therapy
28
clinical features of pityriasis versicolor
salmon/light brown hypopigmented macules that will scale when scraped off
