1
Q
define goat
A
An acute arthritic process, which develops from the accumulation of uric acid
2
Q
general characteristics of goat pts
A
- usually affect men older than 25 and women who are post-menopausal
- initial presentaiton is usually a PAINFUL ATTACK of monoarticular arthritis
- Various precipitating factors (trauma, alcohol, surgery, diet, and drugs)
3
Q
primary vs secondary gout
A
- Primary
- inherited as idiopathic or secondary to a defect in purine metabolism leading to overproduction of uric acid
- Secondary
- result of an inherited disorder or the result of over production due to increase of cellular turnover, or in under secretion
4
Q
differentials of goat
A
- crystal arthropathies
- infection –> cellulitis or osteomialitis
- sarcoidosis
- trauma
- SEPTIC JOINT
- fracture
- osteoarthritis
- pseudogout –> inflammation isnt as intense
5
Q
symptoms of goat
A
- pain of the involved joint
- redness
- swelling
- mild fever and chills
6
Q
4 phases of gout
A
- asymptomatic hyperuricemia –> high levels of uric acid in system
-
Acute gouty Arthritis
- most pts; hot, painful joint (days or week)
- intercritical gout
- one attack with a sustained high level of uric acid
- chronic tophaceous gout
- high sustained uric acid levels with accumulation of uric acid in different parts of the body
7
Q
criteria for the daignosis of acute gout
A
- maximum inflammation developed within ONE DAY
- more than one attack of acute arthritis
- presents with monoarticular arthritis
- redness is observed over affected joint
- first metatarsophalangeal pain or swelling
- unilateral first metatarsophalangeal joint attack
- unilateral tarsal joint attack
- tophus is sustemected
- HYPERuricemia
- asymmetric swelling within a joint
- subcortical cysts without erosision in radiograph
- joint fluid culture negative for organism
8
Q
Describe the work up for gout
A
- Blood work
- Serum uric acid level = 3-7 mg/dl (normal)
- when they have an acute flare up the uric levels may be NORMAL
- Serum uric acid level = 3-7 mg/dl (normal)
- Joint aspiration - synovial fluid analysis
- thick straw colored fluid (normal)
- glocose elvel
- WBC should not be present
- septic joint will have WBC present
9
Q
Why the 1st MPJ?
A
- An INCREASE in URIC ACID WILL DECREASE the SOLUBILITY resulting in crystal formation
- trauma or walking initiates a low grade inflammation resulting in lower pH
- decrease in temp of toe
- cooling of the extremities and decrease heart rate while sleeping
10
Q
TX of acute gout
A
- NSAID –> reduces inflammation
- Colchicine –> reduces inflammation
- Corticosteroids –> reduces inflammation
- analgesics
11
Q
long term management of gout
A
- allopurinol –> blocks formation of uric acid
- febuxostat
- probenecid –> increases excretion of uric acid in urine
- sulfinpyrazone
12
Q
Which foods are high in purine content
A
- bacon
- fish: anchovies, codfish, herring, salmon, sardines, trought
- kidneys
- liver
- shellfish
- veal
- venison
- turkey
13
Q
causes of sustained hyperuricemia
A
- ACQUIRED
- alcohol consumption
- exercise
- fructose consumption
- high purine intake
- myeloproliferative disorders
- obesity and hypertriglyceridemia
14
Q
Uric acid lithiasis
A
- development of stone or calculus composed of urate precipitate within the bladder, ureter or renal pelvis
- conc of uric acid in urine exceeds its solubility at the urine pH, uric acid chagnes from a compound dissolved insolution to insoluble precipitate
- URATE STONES FORMED BY:
- overproduction
- increased tubular secretion
- decreased tubular reabsorption
- WORK UP = 24 hour urinalysis, CT scan, urine chem
- TX = HYDRATION
