TO FELLOW’S CHALLENGE MAY-JUNE
2004 PROJ

Potential questions/controversies regarding disease
characteristics* and optimal matching answers:
1) Increased aldolase: We have seen it in not only JDM
but systemic JIA, MCTD, and PAN reflecting myositis in these entities.
2) ANA + 1:160 is very non-specific in this low titer
and can be seen in JIA poly and oligo, SLE, JIA-psoriatic, Crohn’s, JDM,
systemic scleroderma, local scleroderma, MCTD, Lyme disease and leukemia.
3) Chronic uveitis can occur in many diseases in
rheumatology but is common in children with oligoarticular and polyarticular
JIA (not systemic), sarcoid, psoriatic arthritis, Crohn’s disease and Behcet’s
(major criterion). Chronic uveitis can be seen in Lyme disease and MCTD, but
infrequently. JIA-spondy and Reiter’s
syndrome usually are associated with an acute uveitis. Other causes of uveitis
not mentioned in this exercise include CINCA/NOMID syndrome and
4) HIP pain/loss of ROM common - So what diseases in our
neighborhood commonly attack the hip? Certainly systemic and polyarticular JIA
often involve the hips of children as well as psoriatic arthritis and
spondyloarthropathies (here JIA-spondyl and Reiter’s). SCFE always involves the
hips and AVN frequently. ALL, Crohn’s, UC, MCTD, and sarcoid arthritis may
involve the hip but we would argue that these involvements are not “common”.
5) So who comes into your clinic as a new patient in a
wheelchair? This is typical for severe pain augmentation syndromes such as
reflex sympathetic dystrophy and fibromyalgia. Anyone with severe hip disease
may come to the first clinic visit in a wheelchair, but this is more typical of
AVN and SCFE than JIA. The JIA patients must have very severe disease for a
number of years to have such severely involved hips and are not often new
patients in your clinic. ALL as well as neuroblastoma and osteogenic sarcoma
patients may come into your clinic in a wheelchair as they often have severe
bone pain and much functional loss. In all of the other listed diseases,
children with very severe disease might come in using a wheelchair but we would
argue that those episodes are very infrequent. What’s the purpose of this
question?... New patient in a wheelchair, think pain syndrome, malignancy, hip
disease.
6) Night pain and low platelets: suggestive of ALL.
7) AVN can occur without prednisone in SLE, perhaps due
to APLA, vasculitis, or other SLE mechanisms.
8) Arthritis in one or more toes with an isolated finger
is very suspicious for psoriatic disease and rarely happens with classic JRA
subtypes.
9) Shrunken finger with a hard line down palm is seen
with severe linear scleroderma that produces very severe lesions.
10) Out of school for long periods is very suggestive of
fibromyalgia. JIA kids seem to be less disabled functionally.
11) Very large skin ulcerations are classic for JDM and
not infrequently seen in Crohn’s and
Wegener’s as opposed to the smaller skin ulcers of SLE and systemic
scleroderma.
12) Mother and daughter have the same disease: I favor
psoriasis the most here, but certainly SLE and rheumatoid factor JRA have to be
mentioned, as well as fibromyalgia.
13) Headaches, coma, abnormal MRI, brain biopsy: Isolated
CNS vasculitis would be the first thought but Behcet’s, and rarely SLE, might
cause this clinical scenario.
