23

treatment of mild acne (pharmacological)

Topical benzoyl peroxide (2.5%-10%). If not responsive, retinoid acid (0.025% to 0.1%) cream or gel pregnancy category C. Tretinoin is inactivated by UV light and oxidized by benzoyl peroxide, should only be applied at night and not with benzo peroxide
Also salicylic acid and topical antibiotics (erythromycin or clindamycin)

24

Pharmacological treatment for moderate acne or severe pustular acne

requires systemic antibiotics along with topical treatments
Doxy 100mg BID
Erythromycin 1 gram in 2-3 divided doses
Minocycline 50mg-100mg BID
Severe should be referred

Scalp. Primary treatment is griseofulvin 20mg/kg/day for 6 weeks

27

What is tinea corporis and what is the treatment?

Body ringworm. Topical antifungals (miconazole 2%, ketoconazole 2%)

28

What is tinea cruris and what is the treatment?

jock itch, any topical anti fungal (miconazole 2%, ketoconazole 2%) or terbinafine cream curative in more than 80% of cases when used twice a day x 7 days. Griseofulvin for severe cases

29

What is tine manuum and tinea pedis and what is the treatment

athletes foot. In macerated stage use, aluminum sub acetate solution to soak for 20 minutes twice a day; apply topical antifungals as described in the dry, scaly stage; use oral therapy in sever cases

30

what is Tinea versicolor and what is the treatment?

hypo/hyperpigmentation macules on limbs. Selenium sulfide shampoo for 5 to 15 minutes daily x 7 days; 200mg itraconazole (Sporanox) every day by mouth

31

How long are children infected with varicella contagious for?

Infected individuals are contagious for 48 hours before outbreak and until lesions have crusted over

32

oral acyclovir regimen for varicella zoster

20mg/kg 5x/day given for the first 24 hours can reduce symptoms

33

Diagnostic criteria for Molluscum cantagiosum

puritis, the presence of very small, firm, pink to flesh colored discrete papules, which become umbilicated papules with a cheesy core

34

Atopic dermatitis person may have history of

asthma, allergic rhinitis, atopic dermatitis, elevated serum IgE levels, and a tendency for skin infections

35

hallmark treatment for atopic dermatitis

dry skin management- moisturizing lotion immediately after bathing, must blot dry (aqua for, eucerin)

36

Topical steroid tx for atopic dermatitis and what to do for severe cases

Topical steroids 2-4 times daily, rubbed in well- begin hydrocortisone or other steroids (Fluocinonide cream 0.05%, Desonide, triamcinolone 0.1%), systemic steroids in only extremely severe cases; Prednisone 40mg daily, taper over 5-7 days

37

Management of allergic contact dermatitis

Depends on severity, avoid scrubbing with soap and water
High potency topical steroids locally
If severe and systemic; Prednisone starting at 60mg daily with tapering over 14 days (can manage in primary care)

38

What will fungal infection show under microscope?

When treated with KOH, will show "spaghetti and meatballs" hyphae

39

Management of diaper dermatitis

In mild cases, barrier emollients (zinc oxide products)
When erythema/papules are resent, 1% hydrocortisone (not if suspected fungal infection)
Use burrows (Domeboro) compresses for severe erythema and vesicles
Secondary bacterial infection may need topical antibiotics (mupurocin/ bacitracin)
Secondary fungus may need topical anti fungal
Educate parents about preventative measures
Allow diaper area to dry several times daily

40

Sign and symptoms of psoriasis

Often asymptomatic; itching may occur
Lesions are red, sharply defined plaques with silvery scales
scalp, elbows, knees, palms, soles and nails are common areas
