Homeostatic Imbalances

Athletes foot
Caused by fungal infection
Boils and carbuncles
Caused by bacterial infection
Cold sores
Caused by virus

Contact dermatitis
Exposures cause allergic reaction
Impetigo
Caused by bacterial infection
hyperkeratosis`
un-known, sun exposure, chemicals, etc...
Triggered by trauma, infection, stress
Cyanosis
skin turns blue due to lack of oxygen


Infections & Allergies
Burns
Tissue damage and cell death caused by heat, electricity, UV radiation, or chemicals
Associated dangers
Dehydration
Electrolyte imbalance
Circulatory shock
Rule of nines
Way to determine the extent of burns
Body is divided into 11 areas for quick estimation
Each area represents about 9%
Severity of Burns
First-degree burns
Only epidermis is damaged
Skin is red and swollen
Second degree burns
Epidermis and upper dermis are damaged
Skin is red with blisters
Third-degree burns
Destroys entire skin layer
Burn is gray-white or black
Burns are considered critical if:
Over 25% of body has second degree burns
Over 10% of the body has third degree burns
There are third degree burns of the face, hands, or feet

Skin Cancer
Cancer – abnormal cell mass
Skin cancer is the most common type of cancer
Two stages
Benign
Does not spread (encapsulated)
Malignant
Metastasized (moves) to other parts of the body
Skin Cancer Types
Basal cell carcinoma
Least malignant
Most common type
Arises from statum basale
Squamous cell carcinoma
Arises from stratum spinosum
Metastasizes to lymph nodes
Early removal allows a good chance of cure
Malignant melanoma
Most deadly of skin cancers
Cancer of melanocytes
Metastasizes rapidly to lymph and blood vessels
Detection uses ABCD rule
ABCD Rule
A = Asymmetry
Two sides of pigmented mole do not match
B = Border irregularity
Borders of mole are not smooth
C = Color
Different colors in pigmented area
D = Diameter
Spot is larger than 6 mm in diameter
chicken pox
shingles
eczema
vitiligo
Not cancer, absence of melanin
