| What are merkel cells | basal layer of epi, touch receptors, dev cancer, highly malignant |
| what are Langerhans cells | scatter in epi, made in bone, role of cutaneous immune response |
| what is contained in dermis | highly vascular/collagen/elastin, blood vsls, nerves, lymph, glands |
| apocrine/eccrine | sweat, pheromone glands/reg body temp |
| how does skin age | smooth, less oily, non stink to stink, oily to thin wrinkled, spotty |
| what are actinic keratoses | chronic sun exposure, fair complexion |
| benign neoplasm | seborrheic keratoses, cherry angiomas, skin tags, actinic keratoses |
| what is chief complaint of skin assessment | pruritus antibiotic itching- chest/back most likely to appear |
| what are mongolian spots | blue/black on sacrum/buttocks, african am, asian |
| what is pseudofolliculitis | ingrown hair |
| Primary skin lesions | macule, wheal, vesicle, bulla, papule, cyst, pustule, nodule, tumor |
| Secondary skin lesions | change w/ time erosion, scar, ulcer, keloid, fissure, scales, atrophy, crust, lichenification |
| vascular skin lesions | petechia, ecchymosis, venous star, spider angioma, cherry angioma |
| Terms: confluent | merging together |
| discrete | separate from other lesions |
| satellite | single lesion close to lg grouping |
| zosteriform | bandlike along dermatome area(nerve) |
| Only way to know malignancy wtih skin | biopsy |
| Five rules of skin wound care | 1. categorization 2. selection 3.change 4.evolution 5. practice |
| purpose of wet dressings | reduce inflammation, clean skin of exudates/crusts, maintain drainage, promote healing |
| Occlusive dgs | protect, kept air tight, tegaderm |
| moisture retentive dgs | better at removing exudate, change 12-24hrs, hydrogels(90% h2o, for high serous output), hydrocolloids (water impermeable), Ca alginate(deep wounds, heavy drainage) |
| What are three types of collaborative skin carea | phototherapy radiation therapy - equal to surgery, good for older, debilitated, eyelids/nose/canthal Laser tech: new |
| three diff skin infections | bacterial(pyodermas): impetigo viral: herpes 1/2 fungal: ringworm |
| Impetigo medical mgmt | antibiotics, honey colored crust, contagious |
| what is MDP Maxillofacial death pyramid | nose/mouth area that wounds can lead to brain encephalitis/abscess |
| what are folliculitis | infection of hair follicles, af. am, staph |
| what are furuncles | acute inflammation in hair follicle and spreads, bump gets bigger |
| what are carbuncles | high fever and "walling off" of infection. Diabetes or hematologic malignancies |
| what is tinea pedis | athlete's foot Mgmt: soak foot, keep clean, dry topical antifungals |
| what is tinea corporis Tinea capitis tinea cruris tinea unguium | ringworm of body ringworm of scalp ringworm of groin(jock itch) ringworm of nails |

| Benign tumors of skin | cysts, seborrheic keratoses(wartlike), keloids, moles |
| skin cancer | sun exposure |
| types of skin cancer | basal cell carcinoma- most common, rarely metastisize Squamous cell- can metastasize |
| risk factors for skin cancer | fair skin, living near equator, smoking, exposure to arsenicals, outdoor jobs |

| what is ABCDE rule of assessment | A-asymmetry B-border irregularity C-color, change D-diam 6mm or more(near metastasis E- Evolving/changing |
| where do women tend to get malignant melanoma? men? | W:lowers legs & back M: trunk, head, neck |
| What is most important prognostic factor wtih malignant melanomas | tumor thickness at time of dx |
| If melanoma is in situ what is prognosis | nearly 100% curable, not so in stage IV |
| Type of skin grafts | free grafts(epi/derm), autograft(self), isograft(twin, only one allograft will not reject), allograft(cadaver) xenograft(pig), split thickness, full thickness |
| what is a type of skin graft that allows blood flow | skin flaps, pedicle |
| what is risk for new skin graft | risk of tear, so immobilization |
| Cosmetic surgery techniques | chemical face peel, dermabrasion, facial reconstruction, face lift(rhytidectomy) |
| what are three types of laser tx | argon, CO2, pulse-dye laser |
| what is argon | blue/green light to tx vascular lesions (port-wine stains) |
| what is carbon dioxide laser tx | good for bleeding disorders |
| what is pulse dye laser tx | good for tx cutaneous vascular lesions like port wine, telangiectasia |
