Patho Exam Flashcards
Contact dermatitis
contact with an allergen. Redness (erythema) itching (pruritis)
Scabies
tiny mites, linear burrows in the hands/wrist normally, itching, redness, excoriation
Urticaria or hives
which hypersensitivity
Type I, IgE
Psoriasis
cells build up too rapidly on the skins service, kerantinocytes, psoriatic arthritis
1st degree burns
superficial, erythema, slight pain
2nd degree burns
partial thickness, epidermis and dermis, blistering, pain
3rd degree burns
full thickness, charred skin, numbness
Hemangioma
tumor of blood vessels, usually benign
Lice
pediculosis
feed off of blood
Pressure injuries
prolonged pressure on a bony prominence
Stage I
erythema, non blanchable, skin is still intact
Stage II
skin is not intact, broken through the epidermal layer
Stage III
gone through the subcutaneous tissue, possibly see bone/muscle
Stage IV
Pressure Ulcer
extensive destruction, all the way through, necrosis
Tinea
Ringworm: circular erythematous itchy rash
Strep and staph
skin infections
Shingles
rash of the sensory nerves in a dermatomal pattern, carrying the chicken pox virus, erythematous, vesicular-fluid filled lesions
Where is SKIN cancer normally found on the body?
“arms”
ABCDE
Asymmetry Border Color Diameter Evolving
Mongolian spot
flat bluish gray patch on the lower back, benign, darker color
Albinism
lacking melanin, hair, eyes, skin, all lighter, optic nerve impairment
Molluscum contagiosum
poxvirus infection, small, pink, cone shaped palpules, contagious through direct contact.
Furuncle
boil: can begin in the hair follicles, firm painful nodule, exudate
Rosacea
chronic inflammatory condition that usually affects the face. Erythema and spiderlike blood vessels.
Gout
Too much uric acid in the joint space. Pain, erythema, swelling, warmth. Excessive intake of purines.
Muscular dystrophy
progressive muscle loss, leads to weakness. Cardiomyopathy, muscle spasms.
Osteoarthritis
wear and tear, degenerative joint disease, progress loss of joint function due to repetitive use. Erythema, joint stiffness, loss cartilage, increased pain with weight bearing activity.
Osteoporosis
calcium deficiency: progressive loss leaves bone brittle: imbalance bone resorption and bone formation: brittle: pathologic fractures
Psoriasis can lead
psoriatic arthritis
Lordosis
exaggerated concave curvature of the lumbar spine.
Kyphosis
Curvature of the thoracic spine outward, hunch back, hump
Scoliosis
lateral curvature of the spine: pulmonary compromise
Compartment syndrome
s/p trauma, increased pressure in an internal compartment placing pressure on the nerves and vessels, leading the pain distal the extremity as well as numbness, tingling and lack of pulses
5Ps of compartment syndrome
Pain Pallor Parasthesia Paralysis Pulselessness
3 complications from compartment syndrome
Osteomyelitis: infections of the bone tissue
Osteonecrosis: death of bone tissue due to loss of blood supply
Fat embolism: piece of fat in the blood vessel that breaks off, can go to the heart, lungs or brain. Shortness of breath, confusion, chest pain, petechiae (pinpoint red lesions of chest) on head and chest
Muscle Atrophy
happens to who
muscle loss: elderly, bedrest, cast, paraplegic
Osteomalacia/Rickets
adults/kids: lack of vitamin D, bowlegged appearance
Dislocation
joint is forced out of a normal position.
Hip dysplasia
normally of the children, relaxation of ligaments around the hip joint
Why someone might need an amputation?
Osteomyelitis, gangrene, diabetes
Sprain
ligament
Strain
Tendon or muscle
Herniated disc
pressure on the spinal, disc are protruding into the spinal canal, weakness of the skeletal muscles causing impaired nerve supply
Stress fracture
repeated or excessive activity on the bone
Pathologic fracture
weakness of the bone due to an underlying disease
Oblique fracture
angle of the bone shaft
Transverse fracture
across the bone shaft
Compression fracture
crushed or collapse into small pieces
Rheumatoid arthritis
autoimmune inflammatory disorder, inflammation of the synovial joint, fever, joint pain, joint swelling, erythema
Fibromyalgia
diffuse pain that is poorly understood
Osteogenesis imperfecta
brittle bone disorder, inherited, fractures least of trauma.
