9: Geriatric Skin Disorders - Mahoney Flashcards
decrease in skin lipids –>
dryness
decreased cell replacement –>
roughness, delayed healing
decreased DNA repair –>
increased malignancies
fragmentation of collagen/elastin –>
wrinkles, increase in ulcers
reduced connective tissue support of blood vessels –>
increased purpura
decreased sensation –>
increased injury
impaired thermoregulation –>
vulnerable to heat and cold
reduced function of sebaceous glands –>
decreased lipids
reduced function of sweat glands –>
risk of overheating
decreased langerhans cells –>
delayed healing and increase in infection
reduced subq fat –>
increased risk of injury
flattening of DE junction –>
increased risk of skin tears and blisters
reduced linear nail growth –>
onychogryphosis, longitudinal striations, brittle nails
decreased melanocytes –>
increase in malignancies
extrinsic changes to skin with aging
pruritus
spider veins
age spots
easy bruising and skin breaks
ulcer over bony prominences
pressure over time leads to ischemia and tissue damage
decubitus ulcer
