Eczema definition (general and specific)
-A series of conditions characterized by scaling, crusting, itching, and serous oozing -An interchangeable term for atopic dermatitis
Acute eczema common treatments (4)
-topical steroids -antihistamines -oral steroids -antibiotics
Subacute vs chronic eczematous inflammation
Subacute is most frequently encountered and appears with scaly, scalded appearance Chronic sees lichenification and fissuring
Atopic dermatitis pathogenesis
Many factors may contribute, unsure if immune system causes problem with skin or skin problem causes immune response but manifests as chronic pruritic inflammation of skin
Atopic dermatitis episodes tend to…
…Wax and wane
Family history of atopy 3 big disorder
-eczema -asthma -allergic rhinitis ALL IGA mediated!
Eczema of the infant usualy spares the…
….diaper area
Eczema of children and adolescents often occurs in these locations
-lichen plaques of flexural distribution, palamar aspect of wrists, neck
Atopic hand dermatitis (eczema)
Eczema of the palmar wrists and dorsum of hands seen in those often exposed to “wet work”
Eyelid dermatitis (eczema)
A common feature of atopic dermatitis that has lichenification and presence of Dennie Morgan lines (skin folds under eyes)
Atopic cheilitis definition and how can it be differentatied from perioral dermatitis
-dryness, peeling, fissuring of lips -directly found around the mouth while perioral dermatitis spares the lips (clearing ring around lips)
Superfatted soaps
Best soaps to treat atopic dermatitis (eczema) as opposed to regular soap
First, second, and third line treatment for atopic dermatitis
Topical corticosteroids, systemic corticosteroids (prednisone), topical calcineurin inhibitors (cyclosporine)
Contact dermatitis and 2 subtypes
Dermatitis arising from direct skin exposure to a substance -Allergic induced (immune response to touch) -irritant induced (mechanical damage)
Most cases of contact dermatitis are ___ induced
irritant
Common substances that ellicit allergic contact dermatitis, what is the dermatitis name for those caused by the plant?
-plant oleoresin urushiol (poison ivy and oak) –> Rhus dermatitis -metals -preservatives -fragrances -topical antibioitcs (bacitracin is frequently a source of allergic rxn thats used in tons of ointments)
Rhus dermatitis presents with papules, plaques, or vesicles in this arrangement
Linear or streak like where plant made contact with skin
Sometimes new lesions continue to develop after contact dermatitis exposure up to 21 days. Patients worry that…
….the blisters made it spread (impossible) or they didn’t clean it all off (possible if they are stinky boi) but more likely its just the manifestations of the delayed response
Contact dermatitis treatments (3)
-topical steroids -oral antihistamines -systemic corticosteroid s reserved for severe cases
Diaper dermatitis and 2 subtypes
Frequently occurring skin disorder in children characterizing any inflammatory skin eruption in the diaper area -Contact/irritant (wet diapers often), candida (untreated irritant dermatitis)
Dyshidrotic eczema (acute palmoplantar eczema)
Intense pruritic and chronic dermatitis of unknown cause that involves palms and soles and lateral aspects of fingers where it is unusal to find most dermatitis often seen in young adults
Dyshidrotic eczema (acute palmoplantar eczema) treatment (2)
-Burrows solution (aluminum subacetate) -topical steroids and seran wrap
Nummular eczema
Chronic inflammatory skin disease characterized by pruritic coin shaped lesions often on the extremities (and never on the head) sometimes with central clearing
___ and ___ should be ruled out before diagnosing nummular eczema
Psoriasis, tinea corporus
Seborrheic dermatitis
Dandruff, relapsing skin disorder with erythematous, scaley patches located in areas with high density of sebacious glands such as lateral nasiolabial folds, eyebrows, or scalp
3 choice treatments for sseborrheic dermatitis
-OTC topical agents (Head and shoulders, first choice) -topical antifungals (2nd choice) -oral antifungals (reserved for severe)
Stasis dermatitis, what can chronic sequelae to?
Inflammatory dermatosis of lower extremities in those with chronic venous insufficiency, most often the medial ankle, very common in patients nowadays, chronic can become lipodermatosclerosis
Lipodermatosclerosis
Hyperpigmented and indurated skin constricting ankle region as a result of prolonged stasis dermatitis, gives appearance of inverted champaigne bottle
Asteatotic eczema
Common type of pruritic dermatitis in lower extremities of older individuals that creates fissures on the skin
Perioral dermatitis
Presents with small inflammatory papules around the mouth that spares the vermillion border of the lip, differentiated from acniform by lack of comedomes, self limiting, seen pirmarilyin women btwn 16-45
Treatment for mild, and moderate to severe perioral derrmatitis
-erythromycin -Oral tetracyclines
Lichen simplex chronicus
Appearance of lichenifieid plaque and excoriations usually just one lesion due to excessive scratching of it, noted in anxiety and neurodermatitis (created and perpetuated with no underlying condition)
Lichen simplex chronicus treatment
-Discontinue the itch scratch cycle!!!!
Lichen planus, whats the buzz word with it?
Rare Immune mediated mechanism that causes development between 30’s-60’s of papulosquamous eruption with violaceous (buzz word) papules on skin
Wickham’s striae
Reticulated and lacey marks located on lichen planus eruption
Lichen planopilaris (follicular lichen planus) will result in…
…permanent hair loss
Drugs that induce lichen planus (3 categories)
-ACE inhibitors -B blockers -Diuretics
Lichen planus treatment
-high potency topical corticosteroid
