| Treatment options for subacute eczematous inflammation |
|
Definition
topical steroids (group III through V). If V, may use occlusion. III can be applied up to 4 times daily no longer than 2 weeks. Prefer ointments if it is very dry. Traimcinoloneacetonide 0.1% w/ occlusion is cheap and yields fast effective results.
Topical tacrolimus > pimecrolimus. often need to initiate topical steroids for rapid control until tacrolimus begins to work.
Topical doxepin 5% (zonalon) is good for pruritis. SE's include stinging and drowsiness. Only for >12yo.
Lubrication is vital!!! continue for 2-3 weeks post sxs resolution.
Mild soaps (dove, cetaphil, basis) recommended use sparingly.
Topical tar for steroid resistant cases. |

| chronic eczema appearance and treatment |
|
Definition
inflamed areas thicken and cause surface skin marking to be prominent. Thick plaques cause "washboarding" of skin. The borders are well defined but not as sharply as psoriasis. MC in areas of easy reach from habitual scratching. Pts can scratch unconsciously and while sleeping.
Tx - resistant and require potent steroids. Groups II-V w/ occlusion at night for 1-3 weeks. Group 1 w/o occlusion. Clobetasol foam is effective.
Tacrolimus 0.1% is alternative.
Intralesional injections w/ kenalog 10 mg/mL is very effective. Use 27-30 gauge needle and infiltrate until entire lesion blanches white. can give additional injections at 3-4 weeks intervals. |

Dyshidrosis
aka what?
findings, etiologies, and treatment? |
|
Definition
aka pompholyx
distinctive symmetric vesicular hand/food dermatitis. Moderate to severe inching precedes vesicle appearance on palms and sides of fingers. palms can be red and wet (hence dyshidrosis). Vesicles slowly resolve over 3-4 weeks and are replaced by rings of scale. Chronic eczematous changes may follow. Pain rather than itching is chif complain. Differentiat from psoiais via speed of spontaneous resolution and delay in formation of pustular vesicular fluid.
Etiology - MC cause is mycosis followed by allergic (cosmetic/hygeine products, metals) or idiopathic in atopics. Ingestions of allergens can cause it.
Tx - topical steroids, col compresses. Short oral steroids for acute flares. Responds to PUVA.
Severe non responsive cases may need low dose MTX (15-22.5 mg/week) |
