Childhood Atopic Dermatitis Flashcards
facial area spared by atopic dermatitis
nose
describe AD as a disease
chronic, prururitic, inflammatory skin disease
itch is primary sx, scratching can exacerbate (itch scratch cycle)
AD pres
begin as erythematous papules, coalesce to form plaques that can weep, crust, or scale (top layer of skin)
distribution varies by age:
- cheeks and forehead in infants, extensor areas
- kids- flexural areas
- adults- lichenified flexured regions, moves to hands and face
xerosis (dry skin)
atopic triad
asthma
atopic dermatitis
allergic rhinitis
lichenification
exaggeration of skin lines (like fingerprints)
eczema vs atopic derm
AD is a type of eczematous dermatitis
eczema is non specific inflammatory skin condition w/ erythema, pruritis, scale
tx of atopic dermatitis
long term barrier control: moisture w/ emollients like petrolatum
ID and avoid triggers and irritants
acute inflammation w/ topical steroids, ointments preferred
topical calcineurin inhibs second liine
pruritis tx w/ antihistamines to break itch/scratch cycle
side effects of topical steroids
striae, telangiectasia, atrophy, acne
steroids from strongest to weakest (topical)
clobetasol fluocinonide triamcinolone desonide hydrocortisone
when to do skin bacterial culture
yperacute, weepy flares of AD or wehn pustules or yellow crust present
pts w/ AD susceptible to cutanous infections like staph or group A strep - tx w/ systemic antibiotics
white spots- vitiligo vs inflammatory?
well define borders would be more likely vitiligo
define pityriasis alba
mild asymptomatic form of AD on face
poorly marginated, hypopigmented scaly patches
typically young children in spring and summer
possible secondary presentation of AD on child face
impetigo- honey crusting and bacterial infection
4 contributors to AD pathogenesis
genetics, skin barrier dysfn, impaired immune response, envrionment
tx for pityriasis alba
sunscreen and emollients
