Diagnosis - 7 Ideally the synovial fluid would be tested for crystals, but this is often not practical. Blood tests - testing the serum uric acid level which is higher in men than women. Urine analysis X-ray Bone scan Diagnostic ultrasound Double contour sign
Differential diagnosis Septic arthritis OTHER CRYSTAL DEPOSITION DISORDERS such as: Pseudogout; calcium pyrophosphate deposition disease (CPPD) Hydroxyapatite crystal deposition disease. Osteoarthritis Psoriatic arthritis Reactive arthritis Rheumatoid arthritis Seronegative spondyloarthropathy Haemochromatosis
Management (Conservative) - 6 Weight loss Low purine diet Alcohol reduction Avoid diuretic therapy Local ice therapy Increase fluid intake
Pharmacological - 4 NSAIDS for acute attack (48hours after the resolution) Colchicine (reduces inflammatory response to deposited urate crystals) Corticosteroids (oral or IM) Allopurinol Febuxostat as second-line therapy if allopurinol is not tolerated or is contraindicated.
Podiatric management 8 Limit first MTP movement • long shaft pad • casted and OTS FO • Aspiration of tophus • Injection therapy • Physical therapy • Protection for soft tissues on medial/dorsal aspect • Tophi can cause ulceration – management as appropriate Footwear advice re. soft shoe uppers but firm /rigid thick soles/rocker bar
The Acute Hot Joint - what are you looking for and what do you do?

Summary of sero-negs Group of conditions with overlapping clinical features • Absence of rheumatoid factor in serum • Genetic association with HLA B27 • Common presenting features in the feet of enthesitis, tendonitis, dactylitis • Various levels of deformity and disability present but all will impact on quality of life and ability to undertake ADL
Hypermobility may result from? The shape of joints – Weak / stretched ligaments (differences in biochemical reactions, altered collagen fibres) – Reduced muscle tone – Decreased proprioception – Rare inherited conditions - osteogenesis imperfecta, Marfan syndrome and EhlersDanlos syndrome.
Hypermobility in the lower limb the lower limb • If hypermobility related to collagen, hernias, varicose veins more common • Flat foot, arch pain, • Recurrent ankle sprains • Muscle tenderness, tendonitis • Dislocations • Early OA changes
Scleroderma is a connective tissue disease. It mainly affects........... It may be triggered by? Women Chemicals
Scleroderma results in ? It is an ...............condition. in hard, thickened areas of skin and sometimes problems with internal organs and blood vessel. Scleroderma is an autoimmune condition, which means the body attacks its own tissues. In the case of scleroderma, the connective tissue underneath the skin and surrounding internal organs and vessels is affected. This causes scarring and thickening of the tissue in these areas.
What phenomenon is seen in 90-95% of patients? There is diffuse...................of hands and feet (non-pitting oedema) Ulceration is common. Raynaud's Puffiness
3 main groups • Limited (CREST) • Diffuse • Morphea
Limited (CREST) Limited (CREST) – Long history of Raynauds – Face, arms and legs
Diffuse – Diagnosis with Raynauds or just prior to SSc diagnosis – Internal involvement
Morphea Morphea – Patches – Usually seen in children
Systemic lupus Systemic lupus is a chronic and presently-incurable illness of the immune system, a condition in which the body's defence mechanism begins to attack itself through an excess of antibodies in the blood stream causing inflammation and damage in the joints, muscles and other organs.
Symptoms Raynaud’s phenomenon (80% patients), numbness, tingling, colour changes • Vasculitis, ulceration, necrosis, gangrene • Skin rashes, uticaria
Vasculitis Vasculitis means inflammation of the blood vessels. It can affect any of the body’s blood vessels, causing a variety of symptoms and potential complications. Inflammation causes swelling of the blood vessel walls, reducing or even blocking the flow of blood to tissues and organs. The amount of damage vasculitis causes depends on which part of the body is affected. The larger the affected blood vessels, the more damage there may be. And the more important the affected body tissue, the more serious the damage will be. The walls of affected blood vessels can swell and bulge (this is called an aneurysm) and may even burst, causing bleeding inside your body. Apart from the damage to the blood vessel itself, this can lead to damage in the tissues or organs that are supplied by the blood vessel. -
Occurs as feature of? SLE AND RA
Osteoarthritis Osteoarthritis is a condition that affects your joints. The surfaces within your joints become damaged so the joint doesn’t move as smoothly as it should (see Figures 1 and 2). The condition is sometimes called arthrosis or osteoarthrosis. Older terms are degenerative joint disease or wear and tear. When a joint develops osteoarthritis, some of the cartilage covering the ends of the bones gradually roughens and becomes thin, and the bone underneath thickens. All the tissues within the joint become more active than normal – as if your body is trying to repair the damage: The bone at the edge of your joint grows outwards, forming bony spurs called osteophytes. The synovium (the inner layer of the joint capsule which produces synovial fluid) may thicken and make extra fluid. This causes your joint to swell. The capsule and ligaments (tough bands that hold the joint together) slowly thicken and contract as if they were trying to make your joint more stable.
Symptoms *Pain – The pain tends to be worse when you move your joint or at the end of the day. If you have severe osteoarthritis, you may feel pain more often. *Stiffness – Your joints may feel stiff after rest, but this usually wears off as you get moving. A grating or grinding sensation (crepitus) – Your joint may creak or crunch as you move. *Swelling – The swelling may be hard (caused by osteophytes) or soft (caused by synovial thickening and extra fluid), and the muscles around your joint may look thin or wasted. *Not being able to use your joint normally – Your joint may not move as freely or as far as normal.
