95
Q

Pathophysiology of RA

A

Complex autoimmune attack against synovium of joint (synovitis), this synovium thickens and grows out of the surface of the cartilage (forming a Pannus). Pannus destroys the articular cartilage and subchondral bone (bone erosion). Antibodies incite this inflammation

96
Q

RA presentation

A

SYMMETRICAL joint pain and swelling (also at rest), morning stiffness >30 mins that improves upon activity, joint deformities (Swan neck, Boutonniere, ulnar deviation)

97

99
Q

SPINEACHE - presentation of spondylarthropathies

A

sausage digit, psoriasis, inflammatory back pain, NSAID good response), enthesitis, arthritis, Crohn’s/colitis, HLA-B27, eyes (uveitis)

100
Q

Diagnosis of RA

Serum antibodies - RF, anti-citrullinated peptide antibodies (most sensitive)
X-rays - show soft tissue swelling and joint narrowings
Sterile synovial fluid with high neutrophil count

101
Q

DMARDs used in RA

A

sulfasalanzine - 1st line for most

methotrexate - in more advanced disease (CI in pregnancy)

102
Q

Presentation of septic arthritis

A

Medical emergency, acute onset, most commonly in knee, hot, red, swollen, painful joint, fever

103
Q

Diagnosis of septic arthritis

A

Joint aspiration - purulent synovial fluid, very high WCC

Elevated ESR/CRP

104
Q

Septic arthritis - treatment

A

antibiotics (flucloxacillin, fusidic acid)

105
Q

Crystals in gout?

A

monosodium urate crystals, needle shaped negatively birefringent

106
Q

Pseudogout crystals?

A

calcium pyrophosphate crystals, rhomboid shaped positively birefringent

107
Q

pathophysiology of gout?

A

purines metabolised into hypoxanthine –> xanthine –> uric acid by xanthine oxidase enzymes. Build up of uric acid –> monosodium urate crystals

Intra-articular deposition of crystals, neutrophils detect as abnormal –> inflammatory response

108
Q

Gout presentation

A

Sudden onset pain, swelling and redness of 1st MTP (big toe)

Pain, erythema, swelling, tenderness, warmth

109
Q

Dx gout

A

joint aspiration and synovial fluid analysis - needle shaped negatively birefringent crystals, raised serum uric acid

110
Q

Tx for gout

A

Lifestyle - reduce alcohol, red meat
NSAIDs
If NSAIDs CI –> Colchicine
Long-term management - allopurinol to reduce uric acid levels

111
Q

Pseudogout risk factors

A

Age, DM, OA, joint trauma

112
Q

Pseudogout presentation

A

Often incidental finding, commonly affects knees and wrists, painful attacks that last longer than gout

113
Q

Diagnosis of pseudogout

A

Joint aspiration - positively birefringent rhomboid shaped crystals

114
Q

Tx for pseudogout
