treatment for acne
Treatment - heal existing & stop new lesions Antibiotics Retinoids
1st degree burn
epidermis damaged, red painful
2nd degree burn
epidermis & dermis damaged, red painful AND BLISTERS
epidermis, dermis, hypodermis damaged, hair follicles, sweat glands nerve endings destroyed. NO PAIN, black or white leathery appearance
heat, sun, chemical, radiation, electrical
1st degree burn treatment
cool water (not ice), antibiotic cream, aloe vera (moisturizer)
2nd degree burn treatment
same as 1st, but stronger antibiotic cream
3rd degree burn treatment
skin grafts (from other parts body), if use donor or artificial must be replaced with own skin. IV fluids
>30% of body has 2nd degree burns
>10% of body has 3rd degree burns
CARCINOMA - Squamous Cell
cells of stratum spinosum; appear scaly, red papules and shallow ulcers. Can spread to lymph nodes.
CARCINOMA - Basal Cell
most common and least malignant. Cells of stratum basale. Can invade dermis to hypodermis; appear shiny, dome-shaped nodule becoming an ulcer with pearly beaded edge.
CARCINOMA - Melanoma
cancer of melanocytes (begin wherever pigment is); ABCDE rule for moles(asymmetrical, irregular border, changes in color, diameter >1/4 inch, evolving);
mainly UV radiation
Minor - laser therapy, freezing
Surgery (lesion & surrounding tissue), Mohs surgery (remove
layer by layer to inspect each layer)
Spread- chemotherapy, radiation, immunotherapy
Patches of skin lose pigment or color due to melanocytes attacked and destroyed. Non segmental (most common symmetrical loss on both sides of body) or Segmental (one area on body)
unknown most likely auto immune disease
medication to slow progression (immune system)light therapy
depigmentation - remove pigment around areas
Viral infection (varicella zoster - chickenpox) cause painful rash usually single stripe of blisters wrapped around right or left side of body. Occurs in adults who have had chickenpox.
Virus lay dormant, then unknown reason becomes active again.
antiviral meds, treat symptoms (pain, burning..); vaccine for those >50
Open sores only contagious to those never had chickenpox.
Inflammation in skin and connective tissue. Tricks immune system to respond to inflammation & make too much collagen - causes patches tight, hard skin. Can cause fatigue.
spread to organs
unknown, genetics, auto immune, environment can cause flare ups
treatment SCLERODERMA causes
anti inflammatory meds, corticosteroids, immunosuppressants
Rare disease causing skin to be fragile and blister easily.
EPIDERMOLYSIS BULLOSA treatment
no cure only treatment of symptoms (itching, pain, moisturize)
EPIDERMOLYSIS BULLOSA cause
genetic - protein that helps bind the skin not formed correctly. Auto immune disease
Chronic disease cause inflammation, redness, irritation of skin and oozing along with thickening. Can be localized or multiple areas.
unknown - changes in protective layer of skin loss of moisture; inflammation cause itch; auto immune
control symptoms - dry skin, inflammation, itching skin barriers skin hydration corticosteroid (for inflammation)
blood vessels in extremities narrow, restricting blood flow - affects fingers & toes, ears, nose.Areas turn white to blue due to lack of oxygen.When areas warm up can tingle or burn
: unknown - nerve or hormonal signals; cold temperatures
avoid cold!sympathectomy - destroy nerves trigger blood vessels to constrict approved medication for treatment
Chronic disease where immune system overreacts causing skin cells to multiply too quickly.Types include: plaque, guttate, pustular, inverse Raised, red patches with silvery white scales on scalp, trunk, elbows, knees.
