sign
objectively observable indication of disease or disorder
types of bacteria
- Diplococci
- Staphylococci
- Streptococci
- Bacilli
- Spirochetes
- mycoplasma
diplococci
single cell microorganism - paired cocci - pneumonia
staphylococci
clump together like grapes - methicillin-resistant staphylococcus aureus MRSA
streptococci
chain together - strep throat, rheumatic fever, necrotizing fasciitis
bacilli
elongated, rod-shaped - most capable of forming spores
spirochetes
spiral - syphilis, Lyme disease
myoplasma
tiny microorganisms - some sexually transmitted infections
antiseptic
anything that prevents infection
disinfection
destroys pathogens by exposure to chemical or physical agents
potentially infectious body fluids
semen, vaginal secretion, breast milk, and blood
purpose of inflammation
to protect body, limit range & prepare for healing
inflammation cellular activity
endothelial cells - activate platelets
platelets become jagged and sticky weave net of fibrin with proteins to form blood clots
Final cleanup stage - monocytes and macrophages clean up debris prep for healing
injured cells release factors that form pro-inflammatory chemicals of
- prostaglandins
- leukotrienes
- C-reactive protein
stages of healing
- acute - inflammation stage vasoconstriction, dilation, edema 1-3 days
- subacute - endothelial cells grow into new capillaries 2-3 weeks
- post-acute - remodeling, scar tissue
- chronic - pus is not reabsorbed
anti-inflammatories & massage
schedule session when drug is at its lowest activity to get most accurate feedback
CDC recommended disinfectant
10% bleach solution for high-touch surfaces
dry laundry
on high heat
fissure
cracks in skin
boil
local bacterial infections of the skin
cellulitis
streptococcal infection of deep layers of skin
tinea corporis
ringworm - starts as small round itchy patch & gradually increase in size as fungus spreads
head lice
wingless insects that suck blood from the scalp
acne rosacea
pustules form in more severe cases
malignant melanoma
asymmetric mole with irregular border & mottled color
squamous cell carcinoma
sore that doesn’t heal
second degree burn
involves redness & blisters often scars
decubitus ulcer
bed sores - often seen on back of heels, sacrum & gluts/buttocks
MRSA
methicillin-resistant streptococcus aureus
athlete’s foot
tinea pedis
herpes simplex
virus that never expelled from body but lays dormant & then activates
scabies
tiny mite - spread skin-to-skin contact - itching of unrelenting quality that gets progressively worse
pubic lice
lice located anywhere except for head hair
head lice location
back of head root of hair shaft
mycoses
fungal infections of human skin caused by different types of fungi
how do warts clear up
go away eventually on own if untreated
adolescent acne
caused by excessive amounts of testosterone
onychomycosis
fungal infection of skin under finger or toenails
herpetic sycosis
multiple lesions over beard area - spread by shaving while lesions active
butcher’s warts
associated with meat handling
keloid scars
scar tissue that doesn’t stay within boundaries of skin injury
allergic vs. irritant contact dermatitis
allergic - immune response to substance by affected person
irritant - substance irritating to anyone
rhinophyma
permanent distortion and thickening of skin, usually nose in acne rosacea
comedones
blackheads - hair follicle open to air and sebum turns dark
actinic keratosis
show individual is at risk as this precancerous condition may lead to squamous cell carcinoma
eczema
condition connected to immune dysfunction and hypersensitivity - when pustules massage is locally contraindicated to keep infection from spreading
cancer
uncontrolled replication of cells
melanoma
malignant cancer that penetrates layers deeply and travels through lymph or blood streams
basal cell carcinoma
most common - slow growing
squamous cell carcinoma
chronic skin irritant - can grow in mouth, tongue, cheeks and gums - from mid-range UV light exposure or in long-term skin injury or inflammation sites
Focal epithelial hyperplasia
wart on mouth, lower lip, or tongue - Heck disease
Most common group A beta-hemolytic strep bacteria
necrotizing fasciitis - may cause circulatory shock & death
merruca vulgaris
glow-growing viral infection causing cauliflower-like growths on knuckles
