31
Q

acneiform eruption

A

-may be induced by prolonged use of topical steroids

32
Q

factors associated w/ systemic absoprtion and ADR w/ topical steroid use

A
  • significant hypothalamic pituitary axis suppression
  • systemic absorption –> adrenal suppression
  • cushingoid features (rarely)
33
Q

nonpharmacologic interventions to decrease pruritus

A
  • skin moisturiation
  • gentle cleansers during bathing: dove, olay, cetaphil
  • apply emollients to skin daily

38
Q

tx duration w/ salicylic acid in the tx of warts

A

should not exceed 12 weeks

39
Q

mechanism of cryotherapy for warts

A
  • freezing causes intracellular ice crystals, microthrombi formation leading to ischemic necrosis and destruction of the HPV infected keratinocytes
  • also causes local inflammation that may clear the wart through a cell-mediated process
  • a blister forms under wart and will fall off after 10 days
