Q

What is synovitis and what does it indicate?

A

- Inflammation of the synovial membrane of a joint so it will be hot, painful and swollen

  • In a healthy person it is due to overuse of a joint
  • In inflammatory arthritis it is due to the immune system attacking the synovium and destroying the cartilage
  • Determined by ultrasound to check not tendonitis and then rest/NSAIDs used, sometimes steroid injections are used

26
How do OA and RA differ on X-ray?
**OA:** loss of joint space, osteophytes, subchondral sclerosis, subchrondral cysts **RA:** loss of joint space, bony erosions, periarticular osteopenia, soft tissue swelling, subluxation
27
In the elbow when would you diagnose: - Golfer's elbow - Tennis elbow - Olecranon bursitis

- Provide patient with info about possible causes - Encourage patient to continue activity don't stop - Consider group exercise programme - Consider manual therapy (e.g spinal mobilisation/massage) as a package with exercise and psychological therapy (CBT) - Return to work programme
30
How can lower back pain and sciatica be treated pharmacologically? (not surgically)
**- Do not offer opioids, gabapentins or benzos** and if they are already taking warn the patient of the risk if they carry on taking these, could make it worse **- Prescribe oral NSAIDs with PPIS** and think about patients liver and renal function. Lowest dose for shortest time **- Possibly prescribe weak opioid** with or w/o paracetamol for acute back pain not chronic
31

39
How should we treat a case of suspected RA in primary care until a rheumatology appointment is available?
Consider **NSAID with PPI** but think about person's risk factors e.g age, renal function, pregnancy: - Ibuprofen - Diclofenac - Naproxen - Etoricoxib or Celecoxib DO NOT GIVE GLUCOCORTICOIDS BEFORE ASSESSMENT AS CAN MASK SYMPTOMS
40
What drug treatment might be commenced by a specialist once a diagnosis of RA is confirmed?
**- DMARD** within 3 months of symptoms e.g methotrexate, leflunomide, sulfasalazine or hydroxychloroquine if palindromic - Offer **short term bridging glucocorticoid therapy** until DMARD is working or switching DMARDs (2-3 months), or any flares - Use step up therapy if needed and if not responding to conventional DMARDs consider **biologics** - Regular monitoring due to DMARDs
41

**Methotrexate**: pneumonitis, oral ulcers, hepatotoxicity **Sulfasalazine**: rash, lowered sperm count, oral ulcers **Leflunomide**: teratogenicity, oral ulcers, increased BP, hepatotoxicity **Hydroxychloroquine:** irreversible retinopathy
42
What are some of the different biologics used for RA and what are the side effects of biologics?
Used if 2 DMARDs fail **1st line: TNFa inhibitiors:** infliximab, etanercept, adalimumab, certolizumabpegol, golimumab **2nd line: B Cell depletion:** rituximab **3rd line: IL1/IL6 inhibition:** tocilizumab **4th line: Disruption of T Cell synthesis:** abatacept **Side effects:** reactivation of TB and hep B, worsening heart failure, hypersensisitivity
43
What is the role of primary care for a patient with diagnosed RA on specialist treatment?
**- Drug monitoring:** med reviews, blood tests, check concordance - Ensure adult has **access** to specialist care when having a flare and has information about physios, OT, etc - Check for **development of comorbities** e.g HTN, CVD - Identify and manage **flares** - Check anually if meeting treatment targets - Offer more information on disease and how to manage it - Assess need for surgery
44
How can a GP manage an RA flare?
- Exclude septic arthritis - Look at inflammatory markers - Offer **short term** corticosteroids either IM, oral or injection into local joint - Offer NSAIDS - Speak to specialists
45
What self-help and rehabilitative treatment can a GP offer to a patient with RA?
- Advise Med diet, stop smoking, limit alcohol - Relative rest for acutely inflammed joint - Stretching of other joints - Aerobic conditioning - Heat and Ice therapy
46

- Obesity - Female - Increasing age - Trauma - Joint malalignment - Joint laxity - Genetic
49
How can a GP initially manage a patient with OA non-pharmacologically?
**- Provide information** and resources e.g Arthritis Research UK **- Advise self-help** e.g lose weight, local muscle strengthening, aerobic exercise exercises, prevent repetitive movements with hands, TENS, heat/ice packs, orthotics, advise no evidence for acupuncture/nutraceuticals - Offer **psychological support** for any depression and work support e.g occupational health assessment
50
What pharmacological treatment can a GP offer to someone with OA?
**- Paracetamol and topical NSAIDs** regularly not as needed if not controlled - If these don't work stop topical NSAIDs and give **oral NSAIDs** - If this doesn't work consider **weak opioid codeine** or topical capsaicin **- Intrarticular steroid injections** if all of this doesn't work
51
Who can you refer a patient with OA to?
**- Physio** e.g local muscle strengthening, orthotics **- OT** e.g walking aids, hand rails **- Podiatrist** e.g orthotics **- Orthopaedic surgeon** before severe functional limitation **- Mental health services** **- Pain clinic** especially if chronic pain syndrome
52
When should you refer a patient with OA to an orthopaedic surgeon and what can they do for the patient?
- Symptoms of pain, stiffness and impairment not responding to core treatment - Significant impact on the person's quality of life. - Uncertainty about the diagnosis or atypical symptoms. - Sudden worsening of symptoms. **- Joint replacement or fusion** e.g hip, knee, shoulder, elbow **- Arthroscopic Lavage** and **Debridement** may be considered for people with knee OA with a clear history of mechanical locking - Hand involvement may be treated by **excision of the trapezium** or joint fusion.

54
What is osteoporosis and the risk factors for it?
Progressive bone disease characterised by **low bone mass** measured by bone density, leading to an **increased risk of fragility fractures**, considered severe if 2 or more fractures - Age (post menopausal) - Smoking - Low BMI - Long term glucocorticosteroids - Vit D and Ca deficiency - Little exercise - Previous fractures
55
How is osteoporosis investigated?
- DEXA scan - X-ray following fracture with poor density can show osteopenia - QFracture score
56
How is osteoporosis treated?
**- Lifestyle:** keep BMI 20-25, increase activity level, stop smoking, take vit D/Ca supplements or increase level in diet **- Post menopausal women/Men:** oral bisphosphonates, alendronic acid and risedronate sodium. IV bisphosphonates like zoledronic acid if not tolerate orally. Also HRT or Teriparatide if at severe risk of fracture. - Give people undergoing glucocorticosteroid treatment or men undergoing prostectomy bone protection like above - Review meds every 5 years
57
How do oral bisphosphonates work?
Inhibit osteoclast resorption by binding to hydroxyapatite crystals
58
What is the presentation of bursitis like and how would you tell if it was septic bursitis?
- Most common in shoulder, elbow, hip - Swelling around a joint - Often moveable swelling but tender/warm - Develops over several hours or days - History of repetitive trauma or movement - No restriction of movement of the joint **Septic:** fever, local cellulitis, increasing pain, limited mobility, tachycardia, abrasion over swelling.
59
What are some differential diagnoses for olecranon bursitis?
- Gout - Rheumatoid arthritis - Golfer's/Tennis elbow - Cellulitis - Trauma
60
How is non septic bursitis managed?

61
How is septic bursitis managed?
- Aspirate and give empirical antibiotic like flucloxacillin - Consider repeated aspiration - Review after 7 days If signs of septic joint, e.g limited mobility, then refer to hospital immediately
62

65
What is pseudogout and how is it treated?
Deposition of **calcium pyrophosphate dihydrate crystals**, mainly in the cartilage of the knee causing chondrocalcinosis and **acute synovitis** **Treatment:** rest, corticosteroid injections, joint aspiration, colchicine if can tolerate GI side effects, treat metabolic conditions like haemochromotosis If chronic chondrocalcinosis then treat as OA
