Which joints are affected?

A

• Commonly , the joints affected are those near the ends of the fingers, at the base of the thumb, neck, lower back, knee, and hips. It is a degenerative cause often having minute biological changes

Q

OA

PAtho?

A

• The collagen matrix becomes more disorganized causing a decrease in proteoglycan content within cartilage

. • The breakdown of collagen fibres results in a net increase in water content leading towards ‘wear and tear’ arthritis.

Q

OQ

symptoms?

A

• Pain —-> Joint pain associated exacerbated by prolonged activity and relieved following rest.

• Stiffness —-> Morning joint stiffness are often brief lasting less than minutes. The stiffness is often more severe in the morning or following a period of inactivity. Morning stiffness associated with another type of arthritis called ? osteoarthritis usually wears off within 30 minutes.

• Crackling noise &Crepitus when moving a joint.

• Locking Joints

Q

Management for OA?

A

• Non-Pharmacological Strategies : Exercise to strengthen the surrounding ligaments; weight loss(especially if they are overweight)à to reduce the pressure on the joints and education (to avoid further damage)

• Paracetamol/NSAIDS : Can help mask the pain including medications like Paracetamol/Naproxen

• Analgesic: Opioids such as Tramadol may be administered if the chronic pain persists

• Glucosamine/ Chondroitin: May reduce the pain and improve the mobility of the joint (Although this is still under review)

• Surgery: Is a final option in some cases to replace the full joint in severe cases.

Characteristic radiographic findings in osteoarthritis include all of the following EXCEPT:

a) Osteophytes
b) Symmetrical Joint narrowing
c) Subchondral Cysts

22
Q

What is Rheumatoid Arthritis?

A
  • Rheumatoid arthritis is a long-term, progressive, inflammatory condition that causes pain, swelling and stiffness in the joints.
  • It is an autoimmune disease where the joints are mistakenly attacked by the body’s own immune system.
23
Q

RA

are joints bilaterally or unilaterally?

A

The joints are often bilaterally affected where the hands, feet and wrists are often susceptible to injury.

OSCE tips for RA

A
  • Be very critical when taking the history and relate your questions to the American College of Rheumatology.
  • Be observant when inspecting the joints. Is it swollen, deformed, wasted, warm or red? Check the patients temperature (often forgotten).
  • Ask about distribution and timing as referred shoulder pain may present as cervical spondylosis.
  • Various medications including hydralazine are potential causes of joint issues.
31
Q

Rheumatoid arthritis (RA) is different from some other forms of arthritis because it…

a) Its more painful than others
b) Occurs below the waist
c) Symmetrical
d) Occurs above the waist

A

c) Symmetrical

Rheumatoid arthritis (RA) differs from some other forms of arthritis because it is symmetrical, affecting both sides of the body. Other types of arthritis, such as osteoarthritis, may affect only one side of the body

32
Q

RA is more severe in..

a) Men b) Women c) Children d) Kangaroos

A

b) Women

RA tends to affect three times as many women as men, and symptoms may be more severe in women as well. RA tends to affect women at earlier ages, and men seem to have more cases of remission of the disease

33
Q

Rheumatoid arthritis can be cured if diagnosed and treated early

a) True b) False c) Unsure d) All the above

A

b) False

Treatment for RA that is started early on in the disease process can help minimize or slow damage to the joints and impr

34
Q

What Exactly is Gout?

a) Swelling of the joint due to a deposition of calcium pyrophosphate.

38
Q

What is Gout?

39
Q

The joint of the big tow is commonly affected and may result in _____ _______ ____ _______ ______

A

The joint of the big tow is commonly affected and may result in tophi/kidney stones and urate nephropathy.

40
Q

How is gout diagnosed?

A

• Gout is clinically diagnosed as having persistent high serum levels of uric acids which can consequently result in crystallised deposits in joints and tendons.

41
Q

Symptoms of gout?

A
  • Pain —–> Joint pain associated with inflammation, discomfort and redness
  • Fatigue
  • Fever
  • Acute —-> CAN suddenly become symmptomatic without previous warning
  • Flank pain —-> From urate neuropathy
42
Q

Epidemiology of gout?

A
  • Acute attacks occurs in around 1.25 per1000 of adults.
  • Factors affecting gout include: age, race, season of the year.
  • Rates are 2% in males over 30 and females over 50 years of age.
  • More commonly effects the white population
  • Risk factors include previous episodes of gout, age, race, and the season of the year.

44
Q

Differentials for Gout?

A

• Septic Arteritis —> Should be considered if symptoms do not improve with treatment. Other symptoms include: fever, weakness and headaches. Occasionally more then 1 joint is affected.

• Pseudogout —> Having calcium pyrophosphate deposits in the joint instead. Often affecting more than 1 joint and is often associated with osteoarthritis.

• Rheumatoid Arteritis —> A long term autoimmune disorder clinically having stiffness in the morning and worsens following rest

• Psoriatic Arthritis —> Also autoimmune having swelling of the entire fingers and toes ‘sausage like appearance’. Often associated with changes in the nails as well.

• Reactive Arteritis —> Reiter’s Syndrome : Can’t see, pee or climb a tree

45
Q

Management for gout?

A
  • NSAIDS —> First line of treatment dealing with acute episodes.
  • Lifestyle Management —> Weight loss/ Reduced alcohol intake all help reduce uric acid levels and its deposition in the joints. This helps reduce recurrent flare ups.
  • Allopurinol —> A medication used to reduce serum uric acid levels by blocking xanthine oxidase. It is a prevention mechanism.
  • Glucocorticoids —> Found to be just as effective as steroids but ruling out a joint infection is essential before injection.
46
Q

OSCE Tips for Gout

A
47
Q

You may be able to tell when a gout attack is coming by:

a) Tingling feet in the toe
b) Itching of the fingers
c) Redness in the fingers and toes
d) Joint Crepitation

A

a) Tingling feet in the toe

48
Q

Can Gout be diagnosed by a single blood test?

a) Yes b) No

A

b) No

A blood test can measure your uric acid level, but that’s not enough to diagnose gout. Even people without gout can have high uric acid

49
Q

Can aspirin help ease gout?

a) Yes b) No

A

b) No

When you have a gout attack, an NSAID like ibuprofen might help with the pain. However, Aspirin can cause the uric acid levels to increase, which can bring on a gout flare or make a flare worse.
