papulosquamous conditions - psoriasis, seborrhea
metabolic disease - fatty acid defincency
infections or infestations - scabies, candidiasis, herpes, tinea, staphylococcus aureus infections (impetigo)
neoplasms - cutaneous T cell lymphoa
photosensitivity
what demogaphic is affected most by diaper dermtaitus?
infants more then 1 month old can happen earlier
elderly wearing diapers
relationship between moisture and the diaper
it is a moist and humid environment
traps urine and feces
skin adn GI tract flora interact with skin and diaper
edma of the strtaum cornuem alters skin barrier
causes dermatitus:
- skin exposed to water for more then 24 hours is likely to have erosions following friction
- maceration promotes overgrowth of bacteria and yeast
what are some risk factors for diaper dermatitis? (10)
- moisture retention
- friction and contact irritaion
- urine and ammonia
- ammoni ais a knonw skin irritant and can raise pH
- ammonis doesn’t cause dermatituc however it can exacerbate it - Feces and alkaline pH
- lipases and proteolytic enzymes present in feces
- can cause conatct irritant dermatitis
- can raise the skin pH (alkaline) - lose it’s barrier function - some food may increase the pH (high protein diets)
6.infants with atopic or seborheic dermatitis
- incontinuenece - includes elderly
- immobility
- vigorous cleaning (esp with soaps or detergents)

this microorganisms is presnt in 10-12% of babies that don’t have diaper rash
most commonly found in periphery of intense diaper rash
requires drug treament
talk about staph aureas diaper rash
