Case 2 Flashcards
(65 cards)
Branch points for “joint pain”
localization
inflammatory vs not
number of joints
acute vs chronic (timeline)
periarticular pain
painful, limited ROM- with active movement
no pain, unlimited ROM -when PASSIVE
articular pain
limited ROM and painful with ACTIVE and PASSIVE movements
Symmetrical
RA and SLE
Asymmetrical
OA, Reiters syndrome
Psoriatic arthritis
symmetrical or asymmetrical
migratory large joints
rheumatic fever
DIP pain
OA, psoriatic, gout, reiter’s
PIP pain
RA, OA, SLE
NOT in reiter’s or psoriatic
MCP
rheumatoid arthritis, pseudogout, hemochromatosis
Wrist
RA»pseudogut, gonococcal
rare in OA
Sxs that make it and emergency
- want to rule out septic arthritis and other infections
- acute onset, red/hot/swollen, fever/weight loss, weakness, claudication (pain in periphery), burning/paresthesia pain
Infectious arthritis
gonorrhea!!!!!!!!!!!
also chlamydia,
want joint aspiration
Crystalline arthritis
gout or pseudogout
Hemarthrosis
trauma, hemophilia
joint aspiration- checking for?
cell count, gram stain/culture, crystals
Aspiration of normal fluid-
Viscosity, clarity, color, protein, glucose, WBC, PMNs
high viscosity,
clear,
1-2 protein,
glucose=blood glucose
Aspiration: Non inflammatory
Viscosity, clarity, color, protein, glucose, WBC, PMNs
clear yellow,
high viscosity,
3-5 proteins
200-2k WBC,
Inflammatory aspriate
Viscosity, clarity, color, protein, glucose, WBC, PMNs
opaque yellow Low viscosity, 3-5 proteins 2k-100k WBC, >50% PMNs >25--lower than blood glucose
Septic arthritis aspirate
opaque yellow/green variable viscosity 15k-100k WBCs >75% PMNs positive cultures 3-5 protein
hemorrhagic aspirate
BLoody, red variable viscosity 200-2K wbc 50-75% PMNs 4-6 protein glucose= blood glucose
Add infor about crystals
d
Inflammatory vs non inflammatory jt distribution
Inflammatory= symmetric
Non inflammatory= non symmetric
Inflammatory vs non inflammatory changes in pain
Inflammatory- stiff>1 hr, other complaints (fever, malaise), improves with exerceise
Non inflammatory- stiff
