34
Q

Hydroxyapatite

A

Hydroxyapatite (HA) crystal deposition disease (HADD) is a well-recognized systemic disease of unknown etiology that is caused by para-articular and/or intra-articular deposition of HA crystals. The disease is clinically manifested by localized pain, swelling, and tenderness about the affected joint along with variable limitation of joint motion, although not all patients are symptomatic. Plain radiographs may show calcifications of varying size and shape in the para-articular tendons, bursae, and capsule. The disease may be mono- or polyarticular in distribution. The shoulder is most commonly involved with calcification in the supraspinatus tendon. When intra-articular, HA crystals can cause joint destruction. Any joint can be involved; the shoulder is most commonly affected, resulting in “Milwaukee shoulder.” Treatment of HADD usually requires use of analgesics, local heat, needling with or without aspiration of the calcific deposits, steroid injections, and, at times, even surgery for relief of pain.

35
Q

Soft tissue rheumatism vs fibromyalgia

A

Pain should be confined to a specific site e.g. shoulder, wrist etc.

More generalised soft tissue pain – consider fibromyalgia

36
Q

Some patients with reactive arthritis may suffer from a triad of symptoms (Reiters), what is the triad?

A

Urethritis
Uveitis
Arthritis

37
Q

Where does enteropathic arthritis affect?

A

Spine and peripheral joints

38
Q

Nail changes often seen in psoriatic arthritis

A

Pitting and oncholyitis (lifting of the nail from the nail bed)

39
Q

Common sites for enthesitis

A
Common sites for enthesitis are:
at the top of the shin bone
behind the heel (Achilles tendon)
under the heel
where the ribs join to the breast bone
If your ribs are affected, you may experience chest pain, and you may find it difficult to expand your chest when breathing deeply.
40
Q

Dactylitis

A

Sausage digit

41
Q

Common first sign of scleroderma/systemic sclerosis

A

Swelling of the fingers

42
Q

Common enthsopathies in reactive seronegative autoimmune arthritis

A
  • Plantar fasciitis

- Achilles insertional tendonitis

43
Q

Bamboo spine in which condition?

A

Ankylosing spondylitis

44
Q

Which kind of arthritis may someone with ankylosing spondylitis develop?

A

Knee or hip

45
Q

Conditions associated with ankylosing spondylitis

A

Associated conditions include aortitis, pulmonary fibrosis and amyloidosis.

46
Q

Treatment for ankylosing spondylitis

A

Treatment consists of physiotherapy, exercise, simple analgesia and DMARDs for more aggressive disease. Surgery is mainly reserved for hip and knee arthritis and kyphoplasty to straighten out the spine is controversial and carries considerable risk.
