(19 cards)
- Caput ulnae syndrome?
pain, limited motion, dorsal prominence of distal ulna do to diastasis at the radioulnar joint with possible dorsal displacement of the ulna causing extensor tendon rupture.
doorstep/stepladder appearance?
RA - Subaxial subluxation and dislocation – 9%, M/C C3/4 and C4/5, multilevel subluxations
- Caplan’s sydrome ?
pneumoconiosis and RA
50% of pts with suppurative arthritis have?
RA (MC predisposing factor?)
M/C/C of death in pts with RA?
- Infection
- M/C form of JRA?
Polyarticular (50%), 2x M/C in females
bird face?
JCA
(10-30%) do to arrested mandibular growth with normal growth of other facial features
Sweet’s syndrome?
Like psoriatic arthritis, but acute febrile neutrophilic dermatosis
two dermatologic findings in Reiter’s?
- 20-80% have circinate balanitis, a penile lesion. The appearance of this skin lesion varies from a localized superficial ulceration to scaly cutaneous patches.
- Keratoderma blenorrhagicum – characteristic skin lesion on soles of feet and palms, 5-30%, begin as macular and become vesicular and pustular
positive lab test in SLE?
+ve Coomb’s test
- Robert’s syndrome?
SSx of upper GI pain produced by costotransverse arthrosis
- Kashin-Becks disease?
has been attributed to the toxic effects of fungus-contaminated grain, to selenium deficiency, to chronic ingestion of excessive quantities of iron, and to defective mineral content of the grain
endemic in Siberia and other parts of the Far East
- Lofgren’s syndrome?
acute onset of sarcoid with high fever, lymphadenopathy, arthralgia, erythema nodosum, iritis
Kveim test?
for sarcoid.
intradermal injection of 0.2 ml of a 10% saline suspension of sarcoid tissue, look for reaction, 60-80% produce a noncaseating granuloma, seen in 3-4% of pts with other granulamatous diseases

intestinal lipodystrophy
demographic and associated risk factor with Sjogren’s?

severe osteoporosis, joint space narrowing, juxta-articular erosions, may progress to osseous ankylosis, osteonecrosis, 75% involve hip and knee.
CPPD crystals under a micro with polarized light?
crystals are weakly positively birefringent to polarized light
Common discriminating site of involvement with MCRH not characteristic of RA?
destructive changes of distal interphalangeal joints
