MSK Flashcards
risk factors of rheumatoid arthritis
females 30-50 y/o
family hx
genetic susceptibility
smoking
difference in gender incidence of RA
females more likely premenopause
gender equal after menopause age
what is the significance of seropositive RA
usually IgM rheumatoid factor
associated with worse prognosis and more widespread disease with damage
pathophysiology of RA
inflammatory activation causing swelling and pain of tendons/synovial sheaths and joints
leads to pain, swelling, deformities and loss of function
typical presentation of RA
insidious onset, symmetrical polyarticular
female 30-50 y/o
symptoms and signs of RA
red hot swollen painful joints usually fingers/feet but also wrists, knees, shoulders, ankles
tiredness
pain and morning stiffness
limited joint movement
joint deformities
what is seronegative RA
no IgM rheumatoid factor
usually assymetrical involvement, usually affects wrist more than fingers
less widespread and better prognosis
non-articular complications of RA
scleritis and episcleritis sjögrens syndrome bursitis/nodules neuropathy cervical spine compression anaemia
what are rheumatoid nodules
nodules found on pressure poinds usually elbow, fingers, achilles tendon
RA can present as carpal tunnel syndrome - T or F
T
investigation of RA
bloods - ESR CRP, rheumatoid factor, FBC - anaemia
xray, joint aspirate, doppler ultrasound
what kind of anaemia is common in RA
normocytic normochromic anaemia
management of RA
MDT Approach
analgesic and NSAIDs for pain
DMARDs - methotrexate
biologics - TNF-alpha and il-1 blockers
