phenytoin

20
Q

Schobers test positive

A

<5cm–> reduced lumbar flexion

21

ankylosing spondylitis early sign

A

reduced lateral flexion of lumbar spine
loss of lumbar lordosis, accentuate thoracic kyphosis

22

A

low in osteomalacia
high in CKD (2 HPT)

23

mild peripheral/axial disease –> NSAID
moderate/severe –> methotrexate

ustekinumab, secukinumab

alcohol excess
history of parental hip fracture
low body mass index
current smoking

25

26
Q

acute flare of RA

A

oral or intramuscular steroids e.g. methylprednisolone

27
Q

ankylosing spondylitis XR spine features

A

squaring of lumbar vertebrae
syndesmophytes
subchondral erosions and sclerosis
bamboo spine (late and uncommon)

28
Q

osteitis fibrosa cystica

A

late stage primary hyperparathyroidism causing excessive bone resorption

29
Q

septic arthritis length of Abx treatment

A

4-6 weeks

30
Q

TNF-alpha s/e

A

reactivation of TB
CXR prior to screen for latent TB

31
Q

polymyalgia rheumatic key investigation

A

raised inflammatory markers- ESR>40

32
Q

discoid lupus erythematous Tx

A

topical steroids –> oral hydroxychloroquine

32
Q

Pagets affects what bones

A

skull, spine/pelvis, long bones of lower extremities

33
Q

CK in PMR

A

normal

34
Q

Measure uric acid levels in suspected gout (i.e. in the acute setting)

A

a uric acid level ≥ 360 umol/L is seen as supporting a diagnosis
if uric acid level < 360 umol/L during a flare repeat the uric acid level measurement at least 2 weeks after the flare has settled

35
Q

when starting allopurinol

A

NSAID or colchicine ‘cover’

36
Q

Lateral epicondylitis- examination

A

worse on resisted wrist extension/suppination whilst elbow extended

37
Q

CKD vs osteomalacia

A

low phosphate= Osteomalacia
high phosphate= CKD

38
Q

reactive arthritis joint aspirate

A

no organism growth on gram stain

develops after an infection where the organism cannot be recovered from the joint

39
Q

SLE: most specific vs most sensitive test

A

most specific= anti-dsDNA
most sensitive= ANA
