Definition
What are the two areas most often involved with Rheumatoid arthritis
Term
Early morning stiffness lasting an hour or more
Definition
What is a hallmark of ongoing RA inflammation?
Term
New drugs (DMARDs)
New strategy:
Early intervention
Aggressive treatment
Definition
Why is their newfound optimism for RA treatment?
Term
Systemic Lupus Erythematosus
Definition
auto-immune mediated disorder that can cause arthritis
Antibodies are initially directed against DNA/protein complexes
Term
Initial onset similar to RA with Fatigue, malaise, weight loss, intermittent fever

Later, polyarthritis (60%)
Hemolytic anemia (70%)
Renal disease (30-50%)

“Butterfly rash”

Present in 50 – 65%
Definition
Special SLE Symptom
Term
Osteoarthritis
Definition
THE most common cause of disability in the U.S.
Term
“Wear and tear” is involved but…
Key feature may be protein changes in cartilage linked to cytokines (esp. interleukins)
Definition
Cause of Osteoarthritis
Term
Hips and spine are involved
Definition
Main difference of Osteoarthritis compared to rheumatoid arthritis
Term
Steroids (glucocorticoids)
"Cortisone shot)
Definition

Term
Intravenous drug abusers***
Definition
What group of people are more likely to develop Hematogenous Septic Arthritis?
Term
Muscular Dystrophy
Definition
A group of inherited disorders
All are progressive
All produce muscle weakness
Some also cause pain
Term
Duchenne Muscular Dystrophy
Definition
Most common form of muscular dystrophy

Incidence: 30 per 100,000 live births

X-linked recessive mode of transmission
Term
Loss of muscle strength is slow but relentlessly progressive

Death from pulmonary infections is possible beginning in the late teens

Survival past age 30 is rare
Death is most often due to respiratory failure or pneumonia
Definition
Prognosis of Duchenne Muscular Dystrophy
Term
Primary
Secondary (metastatic)
Definition
Two types of bone cancer
Term
Multiple Myeloma
Definition
Malignancy arising in the bone marrow
Most common form of primary bone cancer
Derived from a single plasma cell
Produces larges amounts of antibody
Term
bone pain
Typically in the back and ribs
Worse with movement, better at rest
Definition
Most common symptom in Multiple Myeloma
Term
Bone Pain
Gradual bone marrow failure
"punched out' bone lesions in imaging
Definition
Clinical features of multiple myeloma
Term
Osteosarcoma
Definition
Second most common primary bone cancer but overall a rare cancer
Term
Usually begins in a long bone:
Femur, tibia, humerus

Presenting complaint:
Bone pain
Pathologic fracture

Can metastasize early
To other bones
To the lung
Definition
Clinical Features of Osteosarcoma
Term
“sunburst lesion” or Codman Triangle
Definition
Xray may show what in osteosarcoma?
Term
Paget’s Disease of Bone
Definition
Characterized by one or more bony lesions with:
High bone turnover and…
Disorganized osteoid formation
Term
Can be limited to one bone (monostotic) or multiple bones (polyostotic)

Common sites: skull, femur, tibia, pelvis, humerus

Symptoms:
None or…
Bone pain and/or…
Deafness…
Pathologic fractures
Definition
Clinical Features of Paget’s Disease of Bone
Term
Osteogenesis Imperfecta
Definition
Genetic disorder of collagen production
Insufficient collagen or abnormal collagen
Term
8
Definition
How many types of Osteogenesis Imperfecta are there?
Term
Type I
Definition
What is the most common and mildest type of Osteogenesis Imperfecta?
Term
Type I Osteogenesis Imperfecta
Definition
Gene mutation results in normal but insufficient collagen quantity
Bones fracture easily
Blue color to the sclera
Loose joints and poor muscle tone
Some children with early hearing loss
Term
Type III Osteogenesis Imperfecta
Definition
Gene defect results in poor quality collagen

Bones fracture easily, even before birth
Bone deformities (often severe) common
Spinal deformities common
Short stature due to fractures

Blue sclera, loose joints, poor muscle tone

Hearing loss in some children
Term
Osteoporosis
Definition
Demineralization of bone
Loss of calcium
Osteoclastic activity dominates over osteoblastic efforts
Bone matrix remains normal
Term
Main resulting problem is loss of bone strength and susceptibility to fracture***
