Scabies Infestation of the skin by the itch mite Sarcoptes scabiei Substandard hygienic conditions Frequently involve fingers Scabies Symptoms typically develop 4 weeks after infestation Severe itching, esp. at night Small raised burrows Extensor surfaces of elbows, around nipples, axillary folds, under pendulous breasts, groin Secondary lesions Scabies Scabies Gerontologic Considerations Long term care facilities susceptible to outbreaks Scabies Diagnosis confirmed by scrapings of epidermis Warm soapy bath or shower Permethrin 5% Apply to skin from neck down, leave on 12-24 hours; repeat 1 week Scabies Bedding and clothing washed in hot water and dried on the hot dryer cycle or dry cleaned Topical corticosteroid pruritis>oral antihistamines oral antibiotic if secondary infection Treat family memebers and close contacts Acne Inflammatory disorder of sebaceous glands contiguous with hair follicles inflammatory (pustules, papules, and nodules) noninflammatory (closed and open comedones) lesions Acne Pathophysiology androgens stimulate the sebaceous glands causing them to enlarge and secrete a natural oil (sebum) accumulated sebum plugs the pilosebaceous ducts inflammatory response. Acne Clinical Manifestations Closed comedones>whitehead Open comedone>blackhead inflammation is seen clinically as erythematous papules, inflammatory pustules, and inflammatory cysts. Acne Acne Acne Assessment and Diagnostic Findings Physical examination, evidence of lesions characteristic of acne and age Graded as mild, moderate, or severe based on number and type of lesions Mild Moderate Severe Acne Goals of Management Reduce bacterial colonies Decrease sebaceous gland activity Prevent follicles from plugging Reduce inflammation Combat secondary infection Minimize scarring Eliminate predisposing factors Nutrition and Hygiene Therapy Acne Pharmacologic Therapy Topical Therapy Benzoyl peroxide Salicylic acid preparations Topical retinoids Topical antibiotic Other> azelaic acid, dapsone gel Acne Oral antibiotics>tetracycline, doxycycline, minocycline, erythromycin, azithromycin, trimethoprim-sulfamethoxazole Oral Retinoids> isotretinoin Estrogen therapy>progesterone- estrogen therapies Nursing Acne Monitor and manage potential of skin treatments Patient education> skin care techniques, managing potential problems related to skin disorder or therapy Prevention of scarring Educate about prescribed medications and self care Nursing Acne Monitor and manage potential of skin treatments Patient education> skin care techniques, managing potential problems related to skin disorder or therapy Prevention of scarring Educate about prescribed medications and self care Psoriasis Chronic inflammatory multisystem disorder of the skin Silvery plaques on the skin over the elbows, knees, scalp, lower back, and buttocks Genetic predisposition Exacerbations and remissions Psoriasis Pathophysiology Autoimmune Epidermis becomes infiltrated by activated T cells and cytokines Epidermal hyperplasia Rapid turnover of poorly matured cells resulting plaque like lesions that have silvery, scaly appearance Psoriasis Psoriasis Red, raised patches of skin covered with silvery scales Scaly patches are formed from the buildup of living and dead skin Psoriasis Complications Asymmetric rheumatoid factor-negative arthritis of multiple joints Rheumatology referral Generalized exfoliative dermatitis(erythroderma) Psoriasis Presence of classic plaque like lesions generally confirms diagnosis Psoriasis Goals of Medical Management Slow rapid turnover of epidermis Promote resolution lesions Control the natural cycles of the disease No known cure Psoriasis Medical Management Topical Agents Phototherapy Systemic Agents Psoriasis Medical Management Mild disease Topical agents, possibly in tandem with phototherapy Moderate and Severe disease Topical agents, phototherapy, and systemic treatment Psoriasis Medical Management Topical Agents> used to slow the overactive epidermis Topical corticosteroids Anti Inflammatory effects Psoriasis Medical Management Topical nonsteroidal agents>suppress epidermopoiesis and cause sloughing of the rapidly growing epidermal cells Calcipotrience(Dovonex) Psoriasis Medical Management Topical nonsteroidal agents Continued Tazarotene(Tazorac) Psoriasis Medical Management Intralesional injections Triamcinolone (Aristocort) Phototherapy Methotrexate- first line drug for treatment of moderate to severe Cyclosporine- considered in severe, therapy resistant cases Psoriasis Medical Management Biologic agents-act by inhibiting activation and migration, eliminating the T-cells completely, slowing post secretory cytokines or inducing immune deviation Nursing Management Psoriasis Assess impact of disease on patient and coping strategies psychosocial and physical no cure and lifetime management provoking factors review and explain treatment emollients self care Blistering Diseases Pemphigus Vulgaris Stevens Johnson Syndrome Pemphigus Vulgaris Assessment and Diagnostic Findings Oral lesions painful, bleed easily, and heal slowly. Skin bullae enlarge, rupture, and leave large, painful eroded areas that are accompanied by crusting and oozing. Odor from bullae and the exuding serum Blistering or sloughing of uninvolved skin when minimal pressure is applied (Nikolsky sign) Pemphigus Vulgaris Assessment and Diagnostic Findings Large areas of the body eventually are involved. Most common complications arise when disease process is widespread. Skin bacteria Fluid and electrolyte imbalance Pemphigus Vulgaris Pemphigus Vulgaris Medical Management Prevent loss of serum and the development of secondary infection; promote re-epithelization (i.e., renewal of epithelial tissue). Corticosteroids Immunosuppressive agents Monoclonal antibody- rituximab(Rituxan) Intravenous immunoglobulin (IVIG) Immunosuppressant- cyclophosphamide (Cytoxan) Pemphigus Vulgaris Nursing Management Nursing Management- p. 1847 Toxic Epidermal Necrolysis(TEN)/Stevens- Johnson Syndrome(SJS) TEN and SJS-potentially fatal acute skin disorders Widespread erythema and macule formation with blistering epidermal detachment or sloughing and erosion formation. Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Up to 75% of cases of TEN and SJS are triggered by medication reactions Antibiotics (especially sulfonamides), anticonvulsants, NSAIDs, allopurinol (Zyloprim), and oxicam NSAIDs (e.g., meloxicam [Mobic]) frequently implicated Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Occur in all ages and both genders Older adults who take multiple medications may be at greater risk. Genetic component Cell-mediated cytotoxic reaction Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Clinical Manifestations Conjunctival burning or itching, cutaneous tenderness, fever, cough, sore throat, headache, extreme malaise, and myalgias Followed by a rapid onset of erythema involving much of the skin surface and mucous membranes, including the oral mucosa, conjunctiva, and genitalia. Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Assessment and Diagnostic Findings Histologic studies History of medications known to precipitate TEN or SJS may confirm medication reaction esP. if the medications were prescribed within 4 weeks prior to the onset of illness Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Assessment and Diagnostic Findings CBC results may show leukopenia and anemia. Skin biopsy results confirm the diagnosis Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Medical Management Control of fluid and electrolyte balance, prevention of sepsis, and prevention of ophthalmic complications. Supportive care is the mainstay of treatment. Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Medical Management Precipitating medications discontinued immediately. Treated in burn center Tissue samples for culture IV crystalloid fluids Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Medical Management Thermoregulation, wound care, and pain management Total parenteral nutrition Systemic corticosteroids-controversial IVIG Immunosuppressants Topical agents for skin protection>antibacterial, anesthetic agents Biologic dressings Toxic Epidermal Necrolysis(TEN)/Stevens-Johnson Syndrome(SJS) Nursing Management Nursing Management- p. 1849 Toxic Epidermal Necrolysis(TEN)/Stevens- Johnson Syndrome(SJS)
