4. Epidemiology
• Primary gout = 1.7 : 100,000 / year
• Age < 50 yr. M > F
• Age > 50 yr. M < F
• BMI, Diet, Alcohol, diuretic drug, Lead
poisoning
14. Acute gouty arthritis
Single joint Oligo-polyarticular joint
Intra-articular steroid
injection or NSAIDs or
Colchicine
Renal or hepatic
disease
Normal renal and
liver function
NSAIDs
Colchicine
0.6 mg * 3
Prednisolone
30-60 mg/day then
Taper off in 2 wks.
Taking oral
medications
Unable
Able
Solumedrol IM, IV
100-150 mg/d * 1-2 days
Or
ACTH SC, IM, IV
25-40 IU q 12 hrs * 1-3 days
High risk for cardiac
or GI toxicity
Low risk for cardiac
or GI toxicity
17. Controversy
• Asymptomatic
hyperuricemia
• Criteria for treatment :
1. At least two gout attacks/
year
2. Chronic tophi
3. Coexisting illnesses ex.
Nephrolithiasis
18. Chronic tophi treatment
• **Do not excision**
• Biopsy only to confirm diagnosis
• Check urine uric acid level 24 hr :
Urate overproduction Vs Urate
underexcretion
• Control serum uric acid level < 5 mg/dL
26. Clinical setting
• Elderly age over 55 years
• Mimic to gout
• large joint, most often the knee
• less often the wrist or ankle
• provoked by minor trauma or intercurrent
medical or surgical conditions including
pneumonia, myocardial infarction,
cerebrovascular accident, and pregnancy.
• Parenteral G-CSF, Bisphosphanate
28. Pathogenesis
• The loose avascular connective tissue
matrices of articular hyaline cartilage,
fibrocartilaginous menisci, and of certain
ligaments and tendons are particularly
susceptible to pathologic calcification.
• ANKH is clearly implicated in the
pathogenesis of familial and
idiopathic/sporadic chondrocalcinosis
29. Diagnosis
• Same as Gout
• Positive birefringent
• Lab : CBC, ESR, CRP
• X-ray for chronic case
30. Differential diagnosis
• Gout
• Septic arthritis
• Other crystal arthropathy
• Chronic case Rheumatoid arthritis
34. Introduction
• Progressive muscle weakness
• Genetic disease
• Effect Dystrophin
• Duchenne Muscular dystrophy : Most
common
• Becker Muscular dystrophy : Second most
common

40. Duchene muscular dystrophy
• Most common
• Male
• 1:3500 live male birth
• 1/3 new mutation
• 65% family history
• Onset : age 3-6 years
• Pseudohypertrophy of
calf muscles
Meyeron sign
42. Natural history
• Progress slowly and
continuously
• muscle weakness
– lower --> upper
extremities
• unable to ambulate:
10 year (7-12)
• death from
pulmonary/ cardiac
failure: 2-3rd decade
43. Treatment
• Supportive treatment : Cardiology,
Respiratory
• Prednisolone 0.75 mg/Kg/day
• Surgery required to stabilize skeletal
structure : Scoliosis
• Counseling family for another child
• Specific treatment : PTC 124 *, PRO051**
