Reassurance Exercise Depression treatment Pain relief
29

30
What is the pathological mechanism of gout?
Hyperuricaemia leads to intra articular sodium urate crystals in cartilage. Stress (dehydration, surgery, alcohol) triggers shedding of crystals into joint resulting in inflammation,
31
Broad categories of causes of hyperuracemia. Which is a more common cause of gout?
Impaired excretion (90%) Increased production
32
Causes of impaired excretion of uric acid causing hyperuricaemia and gout
CKD Thiazides Aspirin Lead toxicity Htn Dehydration
33
Causes of hyperuricaemia due to increased urate produciton
High protein diet Age Lactic acid (alcohol, exercise) Obesity Cell turnover (polycythaemia vera, leukaemia, tumour lysis, psoriasis)
34
Acute presentation of gout? Commonly effected joints?
Monoarthropaty, sudden agonising pain swelling and redness Usually lasting one week 1st MTPJ, ankle, wrist, finger, knee
35
Chronic presentation of gout
Tophi Chronic joint pain Kidney stones
36
Investigations in gout
Xray Serum urate Joint fluid asperation
37
What are tophi?
In gout Smooth red tender lumps filled with white fluid Found on joints, ears and achilles tendon
38
Treatment of acute gout attack
NSAIDs Colchicine Intraarticular corticosteroids
39
Big side effect of colchincine
Diarrheoa
40
Chronic treatment of gout
Dietary advice (decrease alcohol, cholesterol and spinach) Allopurinol if \>3 attacks per year, tophi or renal calculi
41
Mechanism of allopurinol? What should be considered?
Blocks xanthine oxidase May induce acute attack so cover with colchicine
42
Risk factors for septic arthrits
Pre existing joint disease Diabetes Immunocompramised Joint replacement Ivdu
43
Typical organisms for septic arthritis
Staph aureus Neisseria gonorrheoa
44
Presentation of septic arthritis
Single joint Acute swelling redness and pain Systemic symptoms in about 50%
45
Tests in septic arthritis?
Aspiration with ms and c Fbc Blood cultures
46
Treatment of septic arthritis

47
Definition of chronic kidney disease"
Impaired renal function for more than three months based on abnormal structure or function OR GFR
48
Stages of CKD
1 - normal gfr, evidence of damage 2 - gfr 60-89, evidence of damage 3 - gfr 30-59 with or without damage 4 - gfr 15-29 with of without damage 5 - gfr
49
What is renal failure?
GFR
50
What is evidence of damage when assessing ckd?
Proteinuria Haematuria Abnormal anatomy Systemic disease
51
Causes of CKD
DM HTN Idiopathic Glomerulonephritis Pyleonephritis Adult polycystic kidney disease Renovascualr disease
52
What should be tested on a patient with suspected ckd?
Dipstick for urine Diabetes Htn Cvd Recurrent UTI For multi system disorders For structural disease
53
What element of history is important in a patient with a chronic kidney disease?
FHx
54
What symptoms may a ckd patient present with?
Uremia Ankle swelling Dysponea Oligourea Amenorrhea and impotance
55
Signs of ckd
Htn Fluid overload Purporia Ballotable kidney
56
Signs and symptoms of uremia
Anorexia Pruritus Uremic frost Vomiting Restless leg Fatigue Yellow tinged skin Pericarditis
57
Blood tests to run in a ckd patient
Glucose Fbc - anaemia U+es
58
What would a kidney with ckd usually look like on uss? What may cause them to be the opposite?
Usually small Infiltrative disorders like amyloidosis or myleoma
59
What tests should be done on urine with ckd?
Dipstick, ms and c, acr / pcr
60
When should a ckd patient have a biopsy?
Rapidly progressive or unclear cause in a large kidney
61
Complications of ckd
Cvd Anaemia Acidosis Bone mineral disorders Non bone calcifications Secondary and tertiary hyperparathyroidism
62
What bone mineral disorders occur with ckd?
Low calcium Osteomalacia Osteitis fibrosa cystica
63
What is osteitis fibrosis cystica
Low vit d so high pth so low calcium so bone reabsorption and cyst formation (2ndry hyperparathyroidism complication)
64
Treatment options in ckd?
Treat reversible cause Limit progression Symptom control Renal replacement therapy
65
How may reversible causes be treated in ckd?
Stop nephrotoxic drugs Control dm Relieve obstruction
66
How can ckd progression be slowed?
Lower bp Treat proteinuria with acei Prevent renal bone disease with calicum supplementation and vit d analoges Modify cvd risk with aspirin and statins
67
What treatment options are available for ckd anaemia?
Iron, b12 folate Epo
68
What treatment options are available for ckd oedema ?
Frusemide Fluid reatriction
69
When should renal replacement therapy be considered?
Symptomatic (pericaridits, encephalopathy, volume overload) Biochemical disturbance (acidosis, hyperkalaemia)
70
Why should preparation occur for rrt in ckd? When?
Mrtality higher if not preplanned When egfr
71
Types of rrt in ckd
Haemodialysis Haemofiltration Peritoneal dialysis Transplantation
72
Different between haemodialysis and haemofiltration
Heamodialysis - diffusion over semi permiable membrane Haemofiltration - pressure driven
73
Benefits of haemodialysis
Days off Low reposibility See others
74
Problems with haemodialysis
Hypotension, Time consuming Many meds Fistual issues
75
Benefits of peritoneal dialysis
Perform overnight Perform at home Better initial preservation of kidneys Less fluid and food restrictions
76
Problems with peritoneal dialysis
Peritonitis Adhesions Infections Eventually degraeds Leaks into scrotum Herniation
77
Benefit of haemofiltration
Fluids replaced so more haemo dynamically stable thus good on itu
78
Problems with kidney transplantation
Immunosupression Rejection Surgical problems
