Rheumatology Flashcards
What age group are most likely to be affected by temporal arteritis?
70-79 y/o (rarely before 50)
What are the clinical symptoms of temporal atreritis?
Unilateral headache - usually temporal Scalp pain - difficulty brushing hair Jaw and tongue claudication Visual symptoms: Diplopia, blurring and temporary monocular blindness Fever, weight loss, fatigue Polymyalgia symptoms
What are the clinical signs of temporal arteritis?
Abnormal temporal artery: typically thickened, tender with reduced or absent pulse
Scalp tenderness on palpation
Transient or permanent visual loss
Visual field defects
Optic disc changes: pale, swollen optic disc (anterior ischaemic optic neuritis)
Retinal changes: pale retina with cherry red spot (central retinal artery occlusion)
Other: cranial nerve palsies, asymmetrical pulses (if large vessel involvement - subclavian)
What is the principle investigation for temporal arteritis?
Temporal artery biopsy
How is temporal arteritis treated?
With visual symptoms: 60-100 mg one off dose prednisolone until further ophthalmic assessment (same day).
Alternatively, intravenous methylprednisolone 500-1000 mg for three consecutive days, then oral prednisolone (~60 mg daily).
Without visual symptoms: 40-60 mg prednisolone daily (minimum 0.75 mg/kg).
What precautions should be taken for long term prescription of steroids?
Bone protection (e.g. bisphosphonates and vitamin D supplementation) Gastric protection (e.g. proton pump inhibitors) Monitoring blood sugar (at risk of steroid-induced diabetes or worsening of glycemic control in known diabetics)
The following clinical features are characteristic of which rheumatological disease?
Swollen, painful joints in hands and feet Stiffening worse in morning Ulnar deviation Swan neck deformity Boutonniere deformity PIP and MCP swelling, DIP sparing
Rheumatoid arthritis
The following features on xray is indicative of which disease:
Loss of joint space
Soft – tissue swelling
Subluxation
Periarticular erosions
Rheumatoid arthritis
How is rheumatoid arthritis managed?
DMARDs: Monotherapy +/- prednisolone
Methotrexate, Sulfasalazine, Leflunomide
TNF inhibitors – if there is no response to 2 DMARDs:
Etanercept, infliximab, Rituximab
Monitor using CRP and DAS28
Flare ups - corticosteroids
What clinical features are seen on xray for a patient with osteoarthritis? (LOSS)
X-Ray Features - LOSS
Loss of joint space
Osteophytes
Subchondral cysts
Subarticular sclerosis
The following clinical features are seen in which rheumatological disease?
Pain worse on movement and towards end of day
Pain improves with rest
Morning stiffness not prolonged
Decreased range of movement
Muscle wasting
Nodules: PIP (Bouchard’s) and DIP (Heberden’s)
Osteoarthritis
How is osteoarthritis managed?
If increased BMI – weight loss + muscle strengthening exercise
Analgesia
1st line NSAIDs and paracetamol
2nd line - NSAIDs and COX -2 inhibitor. PPI needed.
Joint replacement
Psychosocial aid
