  • rupture of the globe

Question 3. What specific features relating to this presentation and the associated injuries will you examine for and why? (5 marks)

Must include: (1 mark each)
  • visual acuity
  • extra-ocular muscle movements for entrapment
  • orbital rims for tenderness/step
Then 2 from (for a maximum of 2 marks)
  • intra-ocular pressure
  • fundoscopy for retinal injury
  • fluorescein stain for abrasion

saq 2.

A 65 year old woman presents to your department with an acutely painful left eye. The pain is extreme, and associated with vomiting. She describes blurred vision on the left, and the sensation of seeing halos around objects. She has no medical history of note, but does admit to wearing contacts.

His vital signs are:
  • HR 110 /min
  • BP 118/79 mmHg
  • RR 22 /min
  • Sats 98% RA
  • T 37.2 oC

Question 1. What is your differential diagnosis? (2 marks)

Must include: (1 mark)
  • torsion of the testicle
Plus others from (0.5 marks each maximum 1 mark)
  • epididymo-orchitis?STD
  • torsion of appendix testis

Question 2. What features will you look for to on examination to confirm the likely diagnosis? (4 marks)

Must include:

  • excruciating pain to even light touch
  • high riding left testicle
  • transverse lie of testicle
  • loss of cremasteric reflex

Question 3. You are asked by the on-call surgical registrar to perform an ultrasound of the testicle, as she is caught in theatre with an expected delay of more than 2 hours. Is this acceptable? Why or why not? (3 marks)

Must include: (in some form thematically) 1 mark each
  • time critical emergency/already on edge of window for salvage
  • definitive answer is gained by surgical exploration NOT ultrasound

Question 1. Discuss CT versus ultrasound this patient with regard to sensitivity, harm and overall diagnostic utility. (6 marks)

Must include: (1 mark each, theme dependent)


non contrast CT:
  • Sensitivity 90%
  • Harm - ionizing radiation
  • Diagnostic utility - good sensitivity, diagnoses other intra-abdominal conditions

Ultrasound
  • Sensitivity ~60%
  • Harm - minimal
  • Diagnostic utility - shows important complications of stones (hydronephrosis), limited utility for other conditions except biliary ones


Question 2. A CT KUB is performed and the image is below. What are the important positive and negative findings? (4 marks)

Picture
Must include:
Positives (1 marks each)
  • stone right mid ureter
  • proximal hydronephrosis/hydroureter


Negatives (1 marks each)

Plus other comments from  (0.5 marks each up to one mark)
