Week 13 Rheumatology Flashcards
1
Q
osteoarthritis
A
- progressive degenerative joint disease
- degeneration of the hyaline cartilage layers in the joints from repetitive use or repetitive trauma
- increasing thickness in the growth plate.
- mono-articular or poly-articular
- asymmetric
- not a systemic disease
- women
- > 50 yrs, obese
2
Q
OA sx’s
A
- gradual onset of symptoms.
- joint pain, stiffness, swelling, tenderness
- fingers, shoulder, hip, knee, or ankle.
- minimal stiffness in the morning → lasts 30
- no redness or warmth
- functional impairment
- gel phenomenon stiffness (“car” moves better when warmed up)
- Pain worse later in the day and after activity, relieved by rest
3
Q
deformities of OA
A
- in OA
- hard bony swellings
- Heberden nodes in DIP joints
- Bouchard’s nodes in PIP joints
- Changes in carpometacarpal (CMC) joint common - base of thumb
4
Q
OA diagnosis
A
- NO xray except for considering joint replacement [xray normal in early stages]
- mod - severe → xray shows joint space narrowing
- osteophyte
- no lab testing
5
Q
OA management
A
- early OA:
- # 1: acetaminophen
- exercise - aerobic
- educate nature of disease
- physical therapy
- tai chi, stretching
- 2nd line: NSAID
- gi bleeding
- CVD
- mod - severe: tramadol
- joint replacement
- corticosteroids
5
Q
what is the grind test?
A
- CMC test
- if pain and crepitus with passive ROM of the thumb
- specific to OA
6
Q
rheumatoid arthritis (RA)
A
- systemic inflammatory arthritis
- Autoimmune
- Often viral trigger
- Leads to erosions of cartilage and bone → deformity
- increases with age
- Women >
7
Q
RA Sx’s / Exam
A
- bilateral & symmetric
- initially in small joints of hands (MCP, PIP), wrists, small joints of feet
- hips, knees, ankles, shoulders, cervical spine
- Morning stiffness lasting longer than 1 hour = inflammatory
- warmth, tenderness, decrease ROM, boggy swelling
- pain and stiffness worse in the morning & better with activity.
- 1st sx → joint pain/stiffness → then systemic symptoms like fatigue, weight loss, numbness and tingling in the hands.
8
Q
rheumatoid factor lab value for RA
A
- Early on in RA, RF can be negative but after 6 months, can be positive for RF
- RF can be elevated in viral hepatitis, lupus, sjogren’s disease
- CCP antibody has higher sensitivity early on in the dz
- Higher than RF in 3 months
9
Q
deformities of RA
A
- Boutonniere: non reducible flexion of the PIP joint; hyper extension of the DIP joint
- Swan neck deformity: hyper extension of the PIP joint with flexion of the DIP joint.
- Result of synovitis stretching, the rupturing the PIP joint through the central extensive tendon.
- subcutaneous nodules over pressure points
10
Q
RA diagnostics
A
- Inflammatory markers = disease activity
- CBC
- Rheumatoid factor
- ANA is usually negative.
- Anti-cyclic citrullinated peptide and anti-mutated citrullinated vimentin
- more sensitive for detecting/diagnosing RA
- develop earlier in the disease process vs RF
- # 1: X-ray
- show articular erosions, osteopenia, and joint space narrowing.
- soft tissue swelling
- ACR classification
- score 6 out of 10 diagnostic of RA
11
Q
RA management
A
-
Assess/manage cardiovascular risk factors yearly
- Leading cause of death
- Screen for infection (TB, hepatitis before starting treatments)
- Immunizations
- Screen osteoporosis, depression
- Non-pharm
- Ice heat
- PT, OT
- aerobic exercises, muscle strength
- improve QOL and reduce structural joint damage
- once dx → refer to rheumatology
12
Q
RA Treatment
A
- First line: methotrexate (DMARDs)
- Early treatment best
- other meds: leflunomide or sulfasalazine
- 2nd line: Biologic if can’t tolerate the DMARD
- DMARD are teratogenic (counsel conception)
- NSAID caution if hx GI bleeding (use Tylenol instead)
13
Q
Psoriatic arthritis
A
- inflammatory arthritis with dermatologic conditions of psoriasis
- 30-50 yrs old men & women
14
Q
Psoriatic arthritis sx’s
A
- DIP joints
- NO MCP involvement
- usually 5 or more joints affected
- asymmetric
- skin rash before onset of psoriasis
- dactylitis - sausage digits
- uveitis
- Enthesitis - inflammation at site where tendon inserts (Achilles tendon or plantar fascia)
- nail pitting (before rash), onycholysis, cracking
15
Q
psoriatic arthritis diagnostics
A
- if have joint inflammation with no rheumatoid factor + typical psoriatic and nail lesions = Caspar CRITERIA
- 3+ suggestive of PA
- Sed rate
- CRP
- Negative ANA
- Negative rheumatoid factor
- Uric acid
- Lipid profile
- HLA allele
- inflammatory markers elevated
- IgA can be elevated in up to 2/3 of patients.
- X-ray confirms
- erosions, osteolysis, and deformities
- Ultrasound/MRI
16
Q
Psoriatic arthritis management
A
1st line: NSAID but most need 2nd line DMARDs (methotrexate, sulfasalazine, leflunomide, azathioprine)
- Refer → rheumatology and dermatology.
- healthy lifestyle, weight loss, exercise, smoking cessation
- PT and OT
- acupuncture and massage
- screen for comorbidities
- higher risk cardiovascular disease.
- BP; diabetes screen
- higher risk cardiovascular disease.
- screen hepatitis and TB prior to the initiation of immunosuppressants
- screen depression.
