Ankle & foot exam
Inspect (SEADS) - front & back, can you walk for me?
Palpate
- temp
- achilles
- both malleoli & anterior joint line
- med/lateral ligaments
- 5th metatarsal & navicular
- feel all bones in foot up to metatarsal head
- check pulses (DP & PT)
ROM
- active: can you dorsi, plantar, inversion eversion and toes too?
- passive: allow me to
POWER:
- against resistance
Special tests:
- talar tilt (calcaneo-fibular ligament)
- talar drawer (talo-fibular ligament)
- squeeze test (if no movement of foot = +) - testing achilles
Describe talar tilt, talar drawer test & squeeze test?
ankle tests:
- talar tilt (calcaneo-fibular ligament)
- talar drawer (talo-fibular ligament)
- squeeze test (if no movement of foot = +) - testing achilles
What is most commonly sprained ligaments in ankle?
High sprain - inferior tibulo-fibular
Low sprain - anterior talo-fibular ligament (ATFL)
Gout risk factors & causes
- high purine (red meats, organ meats, seafood, HFCS)
- alcohol (beer)
- meds (HCTZ, loop diuretics, aspirin, chemo drugs, contrast dye)
Issues with purine metabolism - either under excreter (90%) or over producer
Gout ix & tx
Sx:
- acute: v painful, tender, no pressure, high fever
- chronic: tophi & arthritis
Ix:
- CBC (high WCC), serum uric acid
- synovial fluid analysis (neg birefringent & needle crystals) r/o septic arthritis & gram stain/culture
- x-ray or ultrasound or CT to see deposits
tx:
- acute: NSAIDs or steroids or colchicine
- prevention: allopurinol or XO inhibitors or febuxistat (+/- NSAIDS or steroids for 3-6 months?)
- avoid high purine foods and alcohol, switch meds as needed
Asthma diagnosis
sx: SOB, wheeze, tightness, cough worse at night, FHX
PFTs - FEV1/FVC <70% w bronchodilator reversal >12% (after 20 mins)
XRAY - r/o cancer or infection
Asthma outpatient mx
Education (env control, avoid triggers, asthma action plan, technique & priming inhaler, peak flow meter)
Technique - breathe out fully, breathe in fully & hold 10 sec, out –> shake puffer & wait 1 min before next puff (prime by spraying 4 puffs if new or >2weeks since use)
Inhalers:
- <2x/week: salbutamol 1-2puffs q4-6h PRN
- >2x/week (not daily): salb qid + low dose ICS 1 puff bid (Flovent)
- daily: LABA + med dose ICS (combo - Advair mod dose or Symbicort high dose)
- still uncontrolled: add LABA, LRTA, high dose ICS, oral steroids, consider omalizumab (anti IgE if >12yo)
If using SABA > 4x/day, >2x/week, 1night/week or 2nights/month –> increase
COMBOS:
- Advair (250mg steroid + LABA)
- Symbicort (400mg + LABA)
