Common Skin Disorders Flashcards
Dermatitis (Eczema)
Inflammation - causes itching, redness, skin lesions
Causes of Dermatitis (Eczema)
Allergic or contact dermatitis
Actinic: photosensitivity, reaction to sunlight
Atopic: etiology is unknown, associated with allergic, hereditary, or psychological disorders
Dermatitis (Eczema) - Stages - Acute
Acute - red, oozing, crusting rash, extensive erosions, exudate, pruritic vesicles
Dermatitis (Eczema) - Stages - Subacute
erythematous skin, scaling, scattered plaques
Dermatitis (Eczema) - Stages - Chronic
Thickened skin, inc skin marking secondary to scratching, fibrotic papules, and nodules, postinflammatory pigmentation changes
Dermatitis (Eczema) - Precautions or contraindiciations
Some PT modalities
Avoid use of alcohol
Bacterial infections happen how
bacteria enter through portals in the skin (abrasions or puncture wounds)
Bacterial infections - Impetigo
Superficial skin infection caused by staph or strep
Associated with inflammation, small pus filled vesicles, itching
Contagious, common in kids and elderly
Bacterial infections - Cellulitis
Suppurative inflammation of cellular or CT in or close to skin - usually poorly defined and wide spread
Strep or Staph infection common - can be contagious
Skin is hot, red, edematous
Bacterial infections - Cellulitis - Management and what if untreated
Management with antibiotics, elevation, cool, wet dressings
If untreated can lead to lymphangitis, gangrene, abscess, or sepsis
Bacterial infections - Cellulitis - Who is at increased risk
elderly with diabetes, wounds, malnutrition or those on steroid therapy
Bacterial infections - Abscess
A cavity containing pus and surrounded by inflamed tissue
Result of a localized infection
Commonly a staph infection
Bacterial infections - Abscess healing is facilitated by
draining or incising the abscess
Viral infections - Herpes 1 (herpes simplex)
Itching and soreness, followed by vesicular erruption of the skin on the face or mouth
Cold sore or fever blister
Viral infections - Herpes 2
Common cause of vesicular genital eruption
Spread by sexual contact
In newborns can cause miningoencephalitis - can be fatal
Viral infections - herpes zoster (shingles)
Caused by varicella zoster virus (chickenpox)
Reactivation of the virus lying dormant in cerebral ganglia or ganglia of post nerve roots
Viral infections - herpes zoster (shingles) - s/s
Pain and tingling affected spinal or cranial nerve dermatome
progresses to red papules along distribution of infected nerve
red papules progressing to vesicles develop along a dermatome
Usually also have fever, chills, malaise, GI disturbances
Viral infections - herpes zoster (shingles) - contraindications
heat or ultrasound - can worsen severity of sx
Viral infections - warts
Common, benign infection by human papilloma virus
Transmission through direct contact, autoinoculation is possible
Fungal infections - Ringworm (tinea corporis)
Fungal infection involving the hair, skin, or nails
Forms ring shaped patches with vesicles or scales
Itchy - transmission through direct contact
Fungal infections - Athletes foot (tinea pedis)
Fungal infection of foot - typically between toes
Causes erythema, inflammation, pruritus, itching, and pain
Can progress to bacterial infection, cellulitis if untreated
Fungal infections - transmission
person to person or animal to person
Parasitic infections - caused by
insect and animal contacts
Parasitic infections - scabies (mites)
Burrow into skin, causing inflammation, itching and possibly pruritus
