Thin strip of hemorrhage under the nail seen in endocarditis
What are Janeway lesions?
Flat, painless, lesions seen on the palms and soles of the feet in endocarditis
What is a coloboma?
Cat-like iris slits as a result of failure in embryonic development of the iris
What is a hordeolum?
Stye or infection of the sebaceous gland of the eye usually by staph. Tender to palpation. Treat with anti staph antibiotics
What is a chalazion?
Cyst due to blockage of the meibomian gland. Treat with warm compress to the eye.
What is a pterygium?
Overgrowth of conjunctiva from irritation from the environment
What is blepharitis?
Inflammation of the eyelid due to seborrheic dermatitis or a staph infection
What is the most common murmur in endocarditis?
Mitral regurgitation
Which cardiac conduction defect is most likely in an anti-Ro positive child of a mother with SLE?
3rd degree AV block
What should be given to a pregnant woman with anti-phospholipid syndrome?
Heparin and aspirin
What are the two types of anti-phospholipid syndrome?
Lupus anticoagulant and anti-cardiolipin antibodies
What syndrome is associated with spontaneous abortion, false positive VDRL, and thrombopilia?
Anti-phospholipid syndrome
What is the most accurate diagnostic test for lupus nephropathy?
Renal biopsy
What is the most common histological abnormality in lupus nephritis?
Membranous glomerulonephritis
What is the best therapy for membranous glomerulonephritis?
Prednisone and mycophenolate (or pred + cyclophosphamide)
What is the pulmonary pathology seen in SLE?
Alveolar hemorrhage
What is the most useful test to determine disease activity in SLE?
Complement level (decrease) and increased ds-DNA antibodies. ANA levels do not change with disease activity
What is the ophthalmologic finding in SLE?
Central retinal vein occulusion - no therapy for this
What is the most accurate test for lupus anticoagulant?
