Q

What is the most common location in the hand for the effects of RA to take place?

A

26
Q

What is RF?

A

Rheumatoid factor: measurement of the reactive IgM antibodies seen in the synovial membrane

27
Q

What time table is used to assess the diagnosis of RA?

A

At least 6 week with morning stiffness, pain upon joint motion, swelling of at least 1 joint, and swelling in at least another joint

28
Q

What aspect of the wrist does RA tend to target?

A

Ulnar styloid area

29
Q

What are all the common locations for RA?

A

Hands, wrist, knees, foot, cervical spine

30
Q

What is the term for the marginal erosions seen with RA?

32
Q

How can RA affect the knees?

A

Symmetric loss of joint space of all compartments (also Baker’s cysts)

33
Q

How can RA affect the hips?

A

34
Q

How can RA affect the shoulder?

A

Resorption of the clavicle

35
Q

What is the biggest concern when RA reaches the cervical spine?

A

Q

What is the most common cause of increased ADI?

A

RA

37
Q

Why is pannus in the odontoid region an issue?

A

Possibly narrowing of the canal and therefore compressive the cord

Q

Does JRA more commonly involve one or multiple joints?

A

Multiple

44
Q

How can JRA affect growth?

A

Either stimulate or stunt it

45
Q

How does JRA affect the knee?
