Conclusion
Definitions
Arthritis = inflammation of a joint.
Inflammation = Joint pain, stiffness, tenderness,
redness, hotness, swelling & limited movement.
Mono arthritis = one joint affected.
Poly arthritis > 4 joints affected.
Oligo/pausi-arthritis = 2-4 joints affected.
Acute = < 6 weeks
Chronic = > 6 weeks
Symptoms:
Articular symptoms
Non articular symptoms
Causes
Monoarthritis mimickers:
• Common inflammatory processes occur in the
soft tissues around joints:

Tendonitis of the shoulder.

Olecranon bursitis of the elbow.

• CPPD, Polyarticular gout
• Polymyositis
• Sarcoid arthritis
• Reiter's syndrome

Rheumatologic emergency
• Acute monoarthritis = the joint is infected
until proven otherwise.
• The septic joint must be diagnosed quickly
and managed aggressively to avoid
permanent structural damage.
History
History taking from a patient with
monoarthritis
1. Onset of pain: sudden, in seconds or minutes?
(Consider fracture and internal derangement).
2. Over several hours or 1-2 days? (Consider
infection, crystal deposition diseases,
inflammatory arthritis and palindromic
rheumatism).
3. Insidiously over days to weeks? (Consider indolent
infections, such as mycobacteria and fungi,
osteoarthritis, tumor, and infiltrative diseases).
4. Overused or damaged joint, either recently
or in the past? (Consider traumatic causes).
5. History of IV drug abuse? Recent infection of
any kind? (Consider septic arthritis).
6. Previous acute attacks of joint pain and
swelling that resolved spontaneously?
(Consider crystal deposition and other
inflammatory arthritis).
7. Treatment with a prolonged course of
corticosteroids? (Consider infection or
osteonecrosis of bone).
8. Associated skin rash, low-back pain,
diarrhea, urethral discharge, conjunctivitis,
or mouth sores? (Consider Reiter's
syndrome, psoriatic, or enteropathic
arthritis).
9. History of a bleeding diathesis? treatment
with anticoagulants? (Consider
hemarthrosis).
Is the age of the patient useful in
the differential diagnosis?
I- In children, consider:
• Congenital dysplasia of the hip.
• Slipped femoral epiphysism.
• Monoarticular presentation of JRA.
• Children are unlikely to have GOUT.
II- In young adults, consider:
•
•
•
•
•
Seronegative spondyloarthropathy.
RA.
Internal derangement of the joint.
They are less likely to have GOUT.
A septic- joint is often due to gonococcal
infection.
III- Older adults :
•
•
•
•
•
Crystalline arthritis.
OA.
Osteonecrosis.
Internal derangement of the joint.
A septic joint in these individuals is less likely
due to gonococcal organisms.
• What are the most likely diagnoses in
hospitalized patients with acute
monoarthritis?
• Acute monoarthritis:
* Pyogenic infection
* Acute crystal deposition diseases
• Risk factors known to provoke gout or
pseudogout:
trauma, surgery, hemorrhage, infection
or medical stress such as:
CRF, MI & CVS.
Polyarthritis
• Pains differ:
Polyarthritis = inflammation (swelling,
tenderness, warmth) of > 4 joints by
examination.
Polyarthralgia = pain in > 4 joints without
demonstrable inflammation; eg: SLE, systemic
sclerosis, vasculitis, polymyalgia rheumatica,
and chronic non-inflammatory.
Diffuse aches and pains are poorly localized
symptoms originating in joints, bones, muscles,
or other soft tissues. Polymyalgia rheumatica,
fibromyalgia, polymyositis, and hypothyroidism.
Sequence of joint involvement:
1- Migratory (fleeting) polyarthritis: Symptoms
disappear in the affected joints to reappear in others.
Ex.: ARF, Gonococcal, Viral, early phase of Lyme.
2- Additive: Symptoms persist with addition of new joint
inflammation Ex.: RA, SLE.
3- Intermittent: Attacks of remissions & exacerbations in
the same joint. Ex.:
Gout, sarcoid arthritis, Reiter's syndrome
and psoriatic.
What are the most likely diagnoses in
women aged 25-50 who present with
chronic polyarticular symptoms?
 OA.
 RA.
 SLE.
 Fibromyalgia.
 Benign hypemobility syndrome.
What are the most likely diagnoses in
men aged 25-50 who present with chronic
oligoarticular or polyarticular symptoms?
 Gonococcal arthritis.
 Reiter Syndrome.
 Ankylosing Spondylitis.
 OA.
 Hemochromatosis.
And in patients over age 50 presenting
with chronic polyarticular symptoms?
 OA.
 RA.
 CPPD disease.
 Polymyalgia rheumatica.
 Paraneoplastic polyarthritis.

Morning stiffness
Morning stiffness = time it takes for patients
with polyarthritis to move after arising in the
morning, or after rest.
Site: Affecting hands in RA & back in AS.
Inflammatory arthritis, morning stiffness
lasts > I hour & tends to parallel the activity.
Non-inflammatory, eg. OA, ---MS < 15
minutes.

Investigations
Monoarthritis
• Synovial fluid analysis.:
Most useful diagnostic study in the
initial evaluation of monoarthritis
Almost always indicated
1. Radiograph of the joint: may reveal:
• Normal, OR unsuspected fracture,
• Osteonecrosis, OA, or
• Juxta-articular bone tumor.
• Chondrocalcinosis, a radiologic feature of CPPD
• Chronic fungal or mycobacterial infection.
• Contralateral joint radiograph for comparison.
2. Complete blood count.
•
Leukocytosis + possibility of inf.
Indicated in selected patients
1. Cultures of blood, urine:
Mandatory in septic joint.
2. PT & PTT: when anticoagulation or coagulation
disorder is suspected.
3. ESR, CRP: nonspecific;
significant elevation = inflammation.
Ask for further investigations in
chronic cases:
4. Radiograph of sacroiliac joints:
asymptomatic sacroiliitis in young males
(spondyloarthropathy).
5) Chest radiograph:
pulmonary TB or sarcoidosis.
6) Tuberculin test:
negative test in excluding TB?.
7) Serologic tests: Lyme disease (Borrelia
burgdorferi), RF, ANA, and HLA-B27.
Polyarthritis

• RF
• HLA-B27 antigen
• Synovial fluid analysis
Conclusion
1.Acute monoarthritis = joint aspiration to
exclude septic & crystal- induced arthritis.
2.Chronic monoarthritis > 6 weeks of
unknown cause needs synovial biopsy.
3.Gout does not occur in premenopausal
females or in joints close to spine.
Take your time for final
diagnosis!
• Because many chronic polyarticular diseases require
months or years to diagnose, patience is often
required.
• Many diseases present insidiously with few
objective findings for prolonged times.
• Many diseases initially represent others before
finally take their usual pattern.
• RA, for example, can present as a monoarthritis
before assuming its more typical polyarticular
course.
Take your time for final diagnosis!
(cont.)
• Characteristic laboratory abnormalities may
require months or years to develop.
• The joint symptoms precede the extraarticular features by months or years.
• Joint radiographs may not show
characteristic changes of the arthritis for
months or years.
Not all pts. with +ve RF=RA, nor +ve. ANA = SLE .
