8
Q
What is rheumatoid arthritis?
A
Chronic, systemic autoimmune disease that causes inflammation of connective tissue in joints.
Usually exhibits extraarticular manifestations (outside of the joints)

25
What are the typical deformitites of RA?
1. Ulnar deviation
2. Boutonniere
3. Bunions
4. Swan neck
26
What is ulnar deviation?
Also known as ulnar drift. This hand condition occurs when your knuckle bones or metacarpophalangeal (MCP) joints, become swollen and cause your fingers to bend abnormally toward your little finger.
27
What is Boutonniere?
Flexion of the proximal interphalangeal and the distal interphalangeal joint
28

5. Depression
30
What are we concerned about when a person with RA presents with Rheumatoid nodules?
Our concern is skin breakdown. These nodules are not usually painful-- as they are just inflamed tissue that hardens over time. But overall this increases the risk of skin breakdown.
31
What is important to know about Sjogren's syndrome?
1. Can happen on its own or as a part of RA
32
What does Sjogren's syndrome effect?
1. Targets salivary and tear glands which leads to dry mouth and eyes.
2. Patients may have difficulty swallowing and may be more prone to injections due to dry eyes and dental carriers.
33
Review: These are the systems in the body that RA effects.
1. Pleura: Effusions
2. Lymph nodes: Reactive lymphadenopathies
3. Kidney: amyloidosis
4. Gut: Amyloidosis

6. Nervous system: peripheral neuropathy (mononeuritis multiplex)
7. Eye: scleritis keratoconjunctivitis
8. Pericardium: Effusions
9. Lung: Fibrosis nodules effusion (these pts can be diff. to get off vents) TCDB important because lungs harden
10. Spleen: Splenomegaly
11. Muscle: wasting
12. Skin: Thinning--> ulceration
