MKSAP Flashcards
Typical clinical presentation of Behcet syndrome
Young Male from the Mediterranean region with recurrent painful oral and scrotal/vulvar ulcers and eye inflammation (panuveitis, retinal vasculitis, optic neuritis). They can also have neurological symptoms, GI symptoms, and arthralgia.
How do you establish the diagnosis of Behchets
International scorch guidelines:

Treatment of reactive arthritis
NSAID x 2 weeks —> persistent —> steroids —> persistent for 3-6 months —> DMARDs for RA —> continued therapy for 3-6 months post disease resolution
Rx of IgG4 related disease
Long taper of steroids —> can add rituximab since disease recurs with discontinuation/taper of steroids

- Intermediate - CONS
What is FABER test
Flexion
Abduction
External rotation
Which joints are involved in AS
SI and synovial facet joints of the vertebrae
What is the 40% rule in AS
Patients are most comfortable when then are in 40% flexi on of the spine. Even AG night they use 3-4 pillows to prop to that position. Finally fibrosis and ossification ensue leading to kyphosis
What are the three stages of AS
Inflammation —> fibrosis —> ossification
Patient with AS has chest pain at night and at rest that improved with activity
Enthesitis of the Costco vertebral joints
Which peripheral joints are most commonly involved in AS
Hip and knee
2 DDx for renal disease in AS
- Amyloidosis - more common
- IgA nephropathy
Cause equina in AS. Culprit?
Arachnoid diverticula
HRCT finding in AS
Upper lobe fibrosis
What are the three patterns of joint involvement in IBD associated SpA and which ones correlate with IBD activity
- Isolated SI or with AS
- Type I peripheral: asymmetric oligo articular in BL LE —> correlate with add activity
- Type 2 peripheral: symmetric poly arthritis in UE with wide range join involvement —> independent of IBD activity
Which ass of biologics cause IBD flare

What is MAGIC syndrome?
