  • 3. P.O. Antibiotics • TCN - 500 bid x 8 weeks • Doxycycline - 100 bid x 8 weeks • Minocycline - 100 bid x 8 weeks-too many side effects and high cost • Taper - Do NOT STOP ABRUPTLY
  • 4. Alternatives • Erythromycin - 500 bid • Septra - check WBC’s • Keflex-500 tid
  • 5. Spiranolactone • Diuretic used in cirrhosis of liver • Also an anti-androgen • Useful in females who have cysts around menstruation • 50-100 mg qday continuously
  • 6. Laser treatment for acne • Placebo effect is strong so controlled studies are essential but lacking • INFRARED-1320 and 1450nm wavelength- light absorbed by sebaceous glands-results very poor • INTENSE PULSE LASER (585 nm)-decreased comedones but not inflammatory papules • BLUE LIGHT (415nm)- decreased inflammatory papules • Yeung CK et al Lasers Surg Med 2007 Jan
  • 7. Accutane • Document failure of antibiotics • Baseline CBC, LFT’s ,TG and cholesterol • Two forms of birth control, negative pregnancy tests • MD’s will need to be registered as will patients • Counseling on depression

  • 15. Too Much Hair • Vaniqa – topical cream that breaks the chemical bond of hair – apply 2x’s/day forever – 30% effective – $30/month
  • 16. Hair Removal – pigment of hair absorbs the light and is destroyed – dark hair responds best – hair is always in different growth phases, so treatment has to be repeated several times to catch the phase= EXPENSIVE – Side effects: pigment changes of surrounding skin and scarring
  • 17. Psoriasis • What is it? • How did I get it? • Can I give it to someone else? • Is it associated with anything? • How can I get rid of it?
  • 18. Psoriasis-Tx:Psoriasis-Tx: • Decrease the MITOTIC RATE of skin – Tar (LCD 5% in TAC 0.1% oint) ( Tar emulsions) – topical retinoids (Tazarac) • Decrease the INFLAMMATORY RATE of the skin – Steroid Ointment (mid-potency-1st line) – Calcipotriene (Dovonex Creme)-not on face or groin – Clobetasol/Dovonex combination – Ultraviolet light

  • 21. EczemaEczema • Dry, inflamed skin that becomes “weepy” • Not bilateral and symmetric • No thick scale • No scalp/nail involvement • Topical steroids first line of treatment • Oral cyclosporine was known to turn off inflammation • Now: topical formulation of Cyclosporine
  • 22. EczemaEczema • Tacrolimus (Protopic) and Pimecrolimus (Elidel), newer kids on the block – Great for facial eczema/eyelid eczema – Expensive – Efficacy-???better than steroids – Black box warning-do not use in children under 2, in sunexposed areas for long periods of time

  • 27. Bacterial Skin Infections • Most common pathogen is staph aureus • More methicillin resistant staph causing skin and soft tissue infections in the community
  • 28. Approach to Treatment • If pus-culture it • If abcess –drain it-NO ANTIBIOTICS • Is this true for abcesses with overlying cellulitis ?-designing that study now
  • 29. If no pus: • Tx with methicillin SENSITIVE drugs-first line but have pt return to evaluate for resolution • If recurrent infection, tx with methicillin RESISTANT antibiotics right off the bat Septra, Doxycycline, Clindamycin, Cipro/Levofloxacillin • Consider adding rifampin 600 qd for 5 days or mupirocin ointment for staph eradication
  • 30. Doc-I’ve been on Doxy for 10 days and no change • Most likely problem: 1) Could have been strep 2) Wasn’t bacteria 3) It wasn’t infected but INFLAMED 4) Did not treat the underlying dermatologic disease 5) All of the above are equally likely
  • 31. 5) All of the above are equally likely
  • 32. Strep-may need added coverage with Penicillin, cephalosporins
