29
Pain over the medial aspect of upper tibia
Anserine bursitis
30
Pain on under surface of heel on weight bearing, aggravated by dorsiflexion of foot
Plantar fasciitis - radiographs may show a plantar spur, related to repetitive trauma
31
When should an arthrocentesis be indicated?
Acute monoarthritis Trauma with effusion Anytime you suspect infection, blood, or crystals ONLY get cell count and differential, gram stain and culture, and crystal analysis (chocolate agar if gonorrhea suspected)
32
What do colors of synovial fluids mean?
Clear - not inflammatory Translucent or opaque - inflammatory White and chalky - gout
33
What are the four types of joint fluid?
Normal - clear, viscous, WBC 2000 WBC and >75% neutrophils - septic arthritis, RA, gout spondyloarthritis Hemorrhagic - indicates trauma with or without fracture or coagulopathy
34
What can a WBC alone not do?
Differentiate between inflammatory and septic
35
Chronic oligo articular arthritis of lower extremities, possible knee effusion
Lyme arthritis
36
What are the three stages of Lyme disease?
1 - 3-4 days after transmission - fever, malaise, myalgias, arthralgias, no true arthritis, hallmark is erythema chronicum migrans (ECM) 2 - weeks to months - myalgias and arthralgias, carditis and AV block, meningitis CN vii palsy, conjunctivitis Ns iritis 3 - 5-7 months - arthritis, chronic CNS symptoms of cognitive and memory dysfunction, radiculopathy
37
How is Lyme disease diagnosed?
ElLISA assay for IgG to spirochete confirmed by western blot
38
What causes gout and psuedogout?
Gout - monosodium urate | Psuedogout - calcium pyro phosphate dihydrate
39
Acute extremely painful monoarthritis, cutaneous erythema/tendonitis, fever, leukocytosis, spontaneous resolution in 3-5 days usually, mean time to first recurrence - 11 months
Early gout
40
Granulomatous urate deposits, finger, wrists, knees, olecranon bursa, ears, pressure points involved
Late gout - usually - 10 years after first attack, remissions shorten, chronic inflammation
41
What is the relationship between hyperuricemia and gout?
Alone doesn't imply gout but is always in gout More likely with elevated uric acid but levels can be normal during acute attack 90% have decreased uric acid secretion - idiopathic, CKD, drugs 10% have overproduction (800mg/24hrs) - idiopathic or overproduction
42
How is gout diagnosed definitively?
Demo monosodium urate crystals in joint fluid | Birefringence - yellow urate parallel, blue perpendicular (opposite with CPPD)
43
What are radiographic features of gout?
Tissue swelling early with preservation of joint spaces Erosions with overhanging edge at end of capsule (not in joint) late in disease Little peri articular osteopenia
44
Elderly male with onset of knee swelling and severe pain over hours to days, can be in wrist, shoulder, or ankle
Psuedogout (chondrocalcinosis) - mimics gout
45
Elderly female with symptoms in 2nd and 3rd mcp joints of hand, picture of osteoarthritis with inflammation imposed
Chronic CPPD arthropathy - can also have pseudo rheumatoid with synovitis and pseudo neuropathic with destruction of joint
46
Calcification of knee menisci, triangular cartilage of the wrist, and symphysis pubis, degenerative changes similar to osteoarthritis, inflammatory or blood tinged joint fluid
Chondrocalcinosis
47
What are features of osteoarthritis?
``` Pain with use, little morning stiffness Pain and stiffness with inactivity (churchgoers knee) Sensation of locking or giving away Crepitus with passive movement No useful lab tests ```
48
What is one of the earliest radiographic feature of OA?
Bone marrow edema on MRI
49
What is the most common cause of osteonecrosis?
Trauma | Particularly fracture of femoral neck
50
Progressive bone pain, often worse at night or with use and weight bearing, pain on movement of affected joint, no inflammation
Osteonecrosis - no lab tests for diagnosis | Early signs on MRI include bone marrow edema
51
What is the boutonnière sign in RA?
Flexion of PIP and hyper extension of DIP
52
What is the swan neck sign in RA?
Flexion of DIP and hyper extension of PIP
53
What are lab features of RA?
Rheumatoid factor (anti IgG) Anti CCP Normochromic normocytic anemia Nothing diagnostic by itself
54
What are common viral infections associated with arthritis?
Parvovirus B19 Rubella Hep b and c HIV
55
What are extra articular manifestations of RA?
``` Rheumatoid nodules Keratoconjunctivitis sicca Episcleritis/scleritis Vasculitis Pulmonary nodules/fibrosis ```
56
What is the use of anti CCP tests in RA?
Same sensitivity for RA as RF | utility in diagnosing early RA or differentiating RA from another condition with RF
57
What are general features of seronegative spondyloarthropathy?
Chronic and inflammatory Oligo articular Asymmetric, often involves axial skeleton Strongly associated with HLA B27
58
Axial arthritis, enthesitis, arthritis of hips and shoulder, peripheral arthritis, flexed forward posture
Ankylosing spondylitis
59
What are general features of ankylosing spondylitis?
``` Onset in early adulthood before age 40 Men affected more than women Back Pain typically first symptom Insidious onset Duration more than three months Morning stiffness ```
60
What are the extra articular manifestations of ankylosing spondylitis?
Anterior uveitis - tearing, pain, photophobia, blurry vision, corneal inflammation and edema, monocular Aortitis, aortic insufficiency, heart block Spinal cord damage - spinal fracture, cauda equina syndrome
61
What are the radiographic features of ankylosing spondylitis?
Erosion, sclerosis and fusion of sacroiliac joints Erosion at sites of tendon attachment Ossification of annulus fibrosis, apophyseal joints, and intervertebral ligaments = bamboo spine Bone spurs bridge edges of vertebral bodies
62
Arthritis involving large joints of lower extremities or interphalangeal joints, looks like RA but with DIP involvement, involvement of axial skeleton with or without peripheral joint disease, nail ridging and pitting
Psoriatic arthritis
63
What are x ray and lab features of psoriatic arthritis?
Sausage digits Joint space loss Marginal erosion of DIP and PIP joints ESR and CRP elevated but autoantibodies negative
64
What is Reiter's syndrome?
Triad of urethritis, conjunctivitis, and arthritis | = reactive arthritis
65
What pathogens are associated with reactive arthritis?
Shigella, salmonella, campylobacter, yersinia, chlamydia
66
