Q

A woman having restrictions in moving her knee, without swelling or being hot tender, morning stiffness of 10-15mins. First line?

A

This patient’s presentation is suggestive of knee osteoarthritis, given her age, gradual onset of pain, functional limitation and lack of significant morning stiffness. NICE guidelines regarding osteoarthritis were updated in 2022 and no longer advocate the use of paracetamol or weak opioids unless they are used infrequently and for short-term relief. First-line management for the knee is the use of topical NSAIDs such as topical ibuprofen.

What if XRay is negative for AS but there is suspicion of AS??

A

The next step in the evaluation should be obtaining an MRI. Signs of early inflammation involving sacroiliac joints (bone marrow oedema) confirm the diagnosis of AS

{Pseudogout - weakly positively birefringent rhomboid-shaped crystals}
Calcium pyrophosphate deposition (CPPD) disease or pseudogout. The characteristic finding in joint fluid analysis in CPPD disease is the presence of positively birefringent rhomboid-shaped crystals. These crystals are formed due to the deposition of calcium pyrophosphate dihydrate in the joint cartilage, leading to inflammation and pain.

33
There is pain on the radial side of her right wrist, difficulty gripping objects and her pain worsens when lifting her infant. On examination, there is tenderness over the radial styloid process, and she experiences pain when moving her thumb, particularly when abducting the thumb against resistance. An X-ray demonstrates soft-tissue swelling over the radial styloid only.
"De Quervain's tenosynovitis" [extensor pollicis brevis and abductor pollicis longus tendons] To confirm diagnosis, FINKELSTEIN TEST: "a key diagnostic manoeuvre, performed by grasping the patient’s thumb and ulnar deviating the wrist. Sharp pain along the distal radius confirms the diagnosis, reflecting inflammation of the tendon sheaths."
34
Which factors suggest that underlying condition is a connective tissue disorder?
onset after 40 years unilateral symptoms rashes presence of autoantibodies features which may suggest rheumatoid arthritis or SLE, for example arthritis or recurrent miscarriages digital ulcers, calcinosis very rarely: chilblains
35
How to manage Raynaud's??
Management all patients with suspected secondary Raynaud's phenomenon should be referred to secondary care first-line: calcium channel blockers e.g. nifedipine IV prostacyclin (epoprostenol) infusions: effects may last several weeks/months
36
Which medicine is used for treating Familial Mediterranean fever?
Colchicine { The primary treatment for FMF is Colchicine, which works by reducing inflammation and preventing attacks. It also prevents the complication of systemic amyloidosis which can lead to kidney failure. According to UK guidelines, all patients with FMF should be offered lifelong treatment with Colchicine.}
37
What is FMF and how does it present?
AR disorder, also called RECURRENT POLYSEROSITIS. (2nd decade) more common in people of Turkish, Armenian and Arabic descent. Features - attacks typically last 1-3 days pyrexia abdominal pain (due to peritonitis) pleurisy pericarditis arthritis erysipeloid rash on lower limbs
38
Minimum steroid intake a patient should be taking before they are offered osteoporosis prophylaxis?
Equivalent of prednisolone 7.5 mg or more each day for 3 months. According to the UK guidelines, patients who are taking a dose equivalent to prednisolone 7.5mg daily for three months or more should be offered osteoporosis prophylaxis. This is because prolonged use of corticosteroids at this dose has been associated with an increased risk of osteoporosis and fractures.
39
What is Management of patients at risk of corticosteroid-induced osteoporosis
The RCP guidelines essentially divide patients into two groups. 1. Patients over the age of 65 years or those who've previously had a fragility fracture should be offered bone protection. 2. Patients under the age of 65 years should be offered a bone density scan, with further management dependent:
40
What is the Mill's test?
Diagnose lateral epicondylitis/Tennis elbow {in de Quervain tenosynovitis} Performed Same as Finkelstein test. Arm flexed and fingers extended in Mills test.
41
INTERSECTION SYNDROME?
Pain and inflammation at the wrist, specifically where the first dorsal compartment (abductor pollicis longus and extensor pollicis brevis) intersects with the second dorsal compartment (extensor carpi radialis longus and brevis).
42
Intersection syndrome vs Arthritis?
>Location of Pain: Intersection syndrome pain: Distal Arthritis: involves joint spaces. >Swelling: Intersection syndrome: Localized swelling, Arthritis: diffuse swelling around joints. >Range of Motion: In arthritis, active range of motion may be limited due to joint stiffness; in intersection syndrome, passive movement may remain intact. >Joint Involvement: Arthritis commonly affects multiple joints (e.g., in rheumatoid arthritis), whereas intersection syndrome is localised to the wrist area.
43
Spurling test?
Cervical radiculopathy resulting from nerve root compression within the cervical spine. Test: head tilting towards the affected side combined with applied downward pressure may reproduce radicular arm sensations if positive for nerve root irritation.
44

45
GOUT?
{deposition of monosodium urate monohydrate in the synovium. It is caused by chronic hyperuricaemia (uric acid > 450 µmol/l)}
46
How to manage acute gout?
ACUTE MANAGEMENT: NSAIDs {Max 2 days until after symptoms have settled} and Colchicine (1st line) + PPI -Oral steroids (Pred: 15mg/day) if NSAIDs & colchicine contraindicated. -Intraarticular steroid injection -If already on allopurinol, then continue it.
47
What is the MOA of colchicine?
Binds with Tubulin, then Inhibits microtubules polymerization, and interferes with mitosis. Also inhibits Neutrophil motility and activity. SLOWER ACTION. Reduce the dose if eGFR is 10-50 ml/min and to avoid if eGFR < 10 ml/min. S/E: Diarrhea
48
Indications of URATE LOWERING THERAPY??
Indication MAIN: After 1st attack Other indications: 1) >= 2 attacks in 12 months 2) tophi 3) renal disease 4) uric acid renal stones prophylaxis if on cytotoxics or diuretics

56
What are the guidelines about treating temporal arteritis??
The American College of Rheumatology 1990 criteria requires 3 of the following for GCA diagnosis: 1. Age >50 y/o 2. New onset localised headache 3. Temporal artery tenderness or decreased pulsation 4. ESR >50mm/hr 5. Temporal artery biopsy positive Uncomplicated GCA (no visual involvement and/or jaw/tongue claudication) should be treated with oral prednisolone 40-60mg daily until symptoms and investigations normalise. Complicated GCA (with visual involvement and/or jaw/tongue claudication), as in this scenario, should be given IV methylprednisolone 500-1000mg for 3 days before starting oral prednisolone. As GCA requires long-term steroid therapy bone sparing agents (a bisphosphonate and vitamin D) and a gastroprotective drug (e.g omeprazole) should be prescribed. Also, low dose aspirin should be considered as it has been shown to reduce the rate of visual loss and cerebrovascular accidents in GCA.

All of these symptoms should be present and would be present for 3 months: Debilitating fatigue that is worsened by activity, is not caused by excessive cognitive, physical, emotional or social exertion, and is not significantly relieved by rest. Post-exertional malaise after activity in which the worsening of symptoms: is often delayed in onset by hours or days is disproportionate to the activity has a prolonged recovery time that may last hours, days, weeks or longer. Unrefreshing sleep or sleep disturbance (or both), which may include: feeling exhausted, feeling flu-like and stiff on waking broken or shallow sleep, altered sleep pattern or hypersomnia. Cognitive difficulties (sometimes described as 'brain fog'), which may include problems finding words or numbers, difficulty in speaking, slowed responsiveness, short-term memory problems, and difficulty concentrating or multitasking.
