Q

6 examination for uveitis (3 key + 3 bonus) plus findings for 3 key examinations

Visual Acuity - can be reduced in posterior uvetitis
Pupils - constricted, may be irregular and is sluggish in response to light. Direct and consensual photophobia
Slit Lamp Examination:
- Conjunctiva → diffusely injected conjunctiva with circumcorneal involvement aka “ciliary flush” → no perlimbal sparing as occurs in conjunctivitis. Tearing but no purulent discharge
- Examine cornea, anterior chamber and posterior chamber as well

Bonus:
Red Reflex - may be normal or altered (secondary cataract)
Tonometry - check for secondary glaucoma
Fundoscopy - look for evidence of choroiditis or retinitis, or complications such as retinal detachment

Q

Management of Uveitis (5 points)

A
  • Urgent Referral to Ophthalmology
  • Seek and Treat Underlying Causes + Treat complications such as glaucoma
  • Mydriatics → sympathomimetics such as phenylephrine HCl → this will present formatino of synechiae by pupillary dilation
  • Parasympatholytic Agents → atropine, cyclopentolate → produce mydriasis and cycloplegia which reduces pain and photophobia
  • Topical Corticosteroids following consultation with ophthalmology and consideration of possible infectious aetiology

Q

Investigations of urolithiasis (3 points)

    • Dipstick may also revel nitrites → Urine MCS can suggest UTI
  • Imaging:
    • CT KUB + Xray KUB
      • Follow-up imaging is needed so performing simultaneous scans allow for decrease in exposure to subsequent ionising radiation and provides clue to composition of the stone.
    • U/S in young people who want to avoid radiation + pregnant women
  • Renal Function Test - severe renal failure may alter management decisions
51
Q

Prevention of Recurrent Stones (4 points). Investigations if recurrent stones (6 poitns)

A
  1. Good Hydration → drink to level where urine is clear as renal calculi precipitate from concentrated urine
  2. Low Sodium Diet → increased sodium diet causes increased urinary calcium excretion be reducing calcium reabsorption from urine
  3. Low Oxalate Diet
  4. Low Protein Diet → stones result from acidic urine which is primarily related to protein in the diet

If recurrent stones → further metabolic work-up: serum calcium and uric acid levels, parathyroid levels, 24-hour urinary calcium, citrate and oxalate
