17
Q

Recall (from Step studying) that __________ is specific for RA.

anti-cyclic citrullinated protein

18
Q

What is the upper limit for ESR?

A

20 mm/hr for females and 15 mm/hr for males

19
Q

Citrulline is formed by _______________.

A

deamination of arginine

20
Q

What immunofluorescent pattern can differentiate lupus from scleroderma?

A

Lupus presents with a circular halo around the nucleus, while scleroderma presents with a clumpy pattern in the nucleus (described as nucleolar).

21
Q

Only a small percent of those with high __________ develop gout.

A

uric acid levels in the blood

22
Q

Pseudogout more commonly affects the ______________.

A

wrist and knee (as opposed to the 1st MTP like in regular gout)

23
Q

Nongonococcal septic arthritis is more common in which populations?

A
  • IV drug abusers

* Immunocompromised patients

24
Q

Aspirates of septic joints from a nongonococcal etiology will classically have WBC greater than __________.

A

50,000 (though this is not required for a diagnosis of septic arthritis)

25
Q

What symptoms, other than arthralgia, accompany gonococcal arthritis?

A
  • Skin lesions
  • Fever
  • Tenosynovitis

The above generally precede joint pain in s

26
Q

True or false: PID is usually found concomitant with gonococcal arthritis.

A

False. PID, if it is present, generally occurs before the arthritic symptoms.

27
Q

The only inflammatory arthritis that affects the DIPs is _______________.

A

psoriatic arthritis

RA usually spares the DIPs. OA is a non-inflammatory arthritis.

28
Q

Psoriatic arthritis can present with skin lesions, nail lesions, arthritis, and ________________.

A

dactylitis

29
Q

What causes the dactylitis seen in psoriatic arthritis?

A

Tendon swelling

30
Q

Untreated, psoriatic arthritis can progress to _____________.

A

bone deformity with telescoping of the digits and the “pencil in cup” sign on x-ray

31
Q

There are two classes of disorders that can cause inflammatory polyarthritis: ______________.

A

rheumatoid arthritis and connective tissue disease (including Sjogren’s, SLE, and sclerosis)

32
Q

Palpation of a joint with rheumatoid arthritis will often demonstrate a ___________ feel.

A

spongy

33
Q

Bone erosion from rheumatoid arthritis generally starts in the ____________ area.

A

bare (the area where the synovium connects to the sides of the bone)

34
Q
