Q

what is the treatment for any JIA

Consider ALL treatments!

A
  1. NSAIDS
  2. MTX if that fails
  3. etanercept or infliximab if thats fails (TNF inhibitor)
  4. Local triamcinolone injectino for one or few joints.
  5. only use steroids in systemic/severe
  6. For uveitis use topical CS + dilators. if ineffective, can use MTX or cyclosporine or TNF inhibitors

Q

What are some associated findings outside of the spine with ankylosing spondylitis

idk im worried she will ask

A
  • acute arthritis of peripheral joints (dactylitis)
  • anterior uveitis
  • spondylitic heart disease (AV conduction defects w aortic regurg)
  • pulmonary fibrosis
  • cauda equina fibrosis

NO CONSTITUTIONAL S/S!!!!!

18
Q

Xray of Spine shows sacroiliac joints w bilateral erosions and sclerosis as well as fused vertebral bodies. there seems to be inflammation where the annulus fibrosus attatches to vertebre

A

ankylosing spondylitis

19
Q

How do you tx ankylosing spondylitis

A
  1. NSAIDS
  2. TNF inhibitors (etanercept, infliximab, adalimumab, golimumab)
  3. refer to PT ALWAYS

DO NOT use CS d/t worsening osteopenia

20
Q

Nail pitting and “sausage” swelling of one or more digits suggests what underlying etiology

A

psoriatic arthritis (specifically enthesopathy type)

21
Q

If you have elevation of ESR, negative RH, and high uric acid levels, what are you thinking?

A

psoriatic arthritis

high d/t active turnover of skin by psoriasis

22
Q

Xray of the hand shows maginal erosions of bone and irregular desctruction of joint and bone

“sharpened pencil” sign in the phalanx

A

psoriatic arthritis

23
Q

how do you differentiate psoriatic spondylitis and ankylosing spondylitis on XR?

A

psoriatic spondylitis = asymmetric sacroiliitis and syndesmophytes which are more coarse than those seen in AS

24
Q

How do you treat psoriatic arthritis

A
  1. NSAIDS
  2. MTX if not responsive
  3. TNF inhibs if MTX doesnt work

CS less effective an can cause pustular psoriasis.

25
Q

what 2 meds can exacerbate psoriasis?

A
  • CS - can lead to pustular psoriasis during tapers
  • antimalarials.
26
Q

this diagnosis is precipitated by preceeding GI and GU infections. presents as asymmetric oligoarthritis of the LE

A

reactive arthritis

27
Q

triad of arhritis, conjunctivitis/uveitis, and urethritis is associated with which diagnosis

A

reactive arthritis

28
Q

A pt recently (bout a month ago) contracted an STD, he has been experiencing weight loss and fevers recently, but assumed they were just a result of his new STD diagnosis. he now is having pain and swelling in his left knee and right hip. Synovial fluid analysis of the left knee is culture negative but shows inflammatory markers… what is the likely treatment plan for this man and what does he have

A

reactive arthritis

tx: 1st NSAIDS, 2nd sulfasalazine or MTX, 3rd TNF inhibitors

29
Q

which disease can literally present with 8 different exraarticular manifestations and what are they

def dont learn this if you dont wanna

A

reactive arthritis

30
Q

How do you treat Arthritis associated with IBD

A
  1. tx IBD if its just peripheral arthritis
  2. NSAIDS (1st line for sponylitis)
  3. range of motion exercises, MTX, CS are all kinda on the same line after this
31
Q

Risk factors include IV drug use, endocarditis, damaged or prosthetic joints, compromised immunity

A

septic arthritis

also loss of skin integrity but i felt like that would give it away!

32
Q

MCC of septic arthritis

A

Staph A

MRSA and GBS also common but not as common as Staph A

33
Q

What is the MC site for septic arthritis? How would this change if the pt used IV drugs?

A

MC = knee

“sternoclavicular and sacroiliac joint can be seen in IV drug users” but are incommon in regular people!!

34
Q

synovial fluid analysis shows >100,000 leukocyte count with 90+% polymorphonuclear cells. gram stain and culture is positive for staph A!

what is likely diagnosis

A

septic arthritis

35
Q

what is the treatment of a pt w septic arthritis?

A
  1. hospitalize!!
  2. empiric 3rd gen ceph. (rocephin, cefotaxime, ceftaidime) + vanc!
  3. adjust abx when cultures return
  4. URGENT ortho surg consult!!
  5. drainage of joint typically done w debridement via arthroscopy
36
Q

when would you do OPEN surgicla drainage of a septic arthritic joint

A
  1. conservative tx fails
  2. concomitant osteomyelitis requiring debridement
  3. involved joint cnanot be drained by more conservative measures
37
Q

more common in women who are pregnant or menstruating and otherwise healthy!

A

gonococcal arthritis

38
Q

2-10 small asymptomatic necrotic pustules distributed over the extremities especially on the palms and soles

A

gonococcal arthritis

39
Q

Urethral, thraot, cervical and rectal cultures should ALL be done in which diagnosis

A

gonococcal arthritis

40
Q

treatment of gonococcal arthritis

A
  • Azithromycin + 3rd gen ceph (rocephin, cefotaxime, coftizoxime)
  • draining not typically requirted
41
Q

what are the three diagnoses that can use etanercept

A
  1. ankylosing spondylitis
