1. The time allowed for this examination is THREE hours.

2. Please use a ball-point or fountain pen only. Do not use a felt-tip pen. It produces a script that spreads or is too thick and, therefore, is difficult or impossible to read.

3. Please write or print as legibly as possible. The examiners cannot assign

marks for answers they cannot read.

4. Be as brief and as direct as possible, making use of the space provided after each question.

5. Examination booklets must be returned intact to the invigilator. You may

not copy and/or remove the questions in any way.

6. If a specific number of answers is requested (e.g. list FOUR), do not list more than requested as they will not be marked (e.g. if four are requested, only the first four will be marked).

7. Certain questions might contain more than one page. Please make sure that

you have completed all pages of each booklet.

8. Please affix your candidate number sticker in the space provided on the COVER PAGE of each examination booklet.

NOTE: After test administration, statistical analyses are conducted and a small number of questions may be deleted if they do not meet standards for psychometric validity. Question weighting may vary because of the importance of the question or the number of answers required. Deleted questions are not included when calculating candidates' final scores and unanswered questions are scored as incorrect; therefore, you should answer every question.

There is a standard process for evaluating changes in medicine that occur too late in the test administration schedule to replace or modify any affected examination questions. We advise candidates to answer all questions according to their understanding of current clinical principles and practice. If it is determined that any question has been compromised by new information (newly published findings), that question will be reviewed to ensure that test-taker results are not adversely affected.

Instructions – Please Read Carefully

Model Answer Total 10 marks a) This is a fractured testicle until proven otherwise. (3 marks) b) The ultrasonic criteria for a ruptured or fractured testicle include; i) Irregular outline of the testicle ii) Inhomogeneous texture to the testicle iii) Discrete fracture line can be seen in 17% (3 marks, 1 for each item) The candidate may note that there is blood supply, which is important but doesn’t rate a mark as it doesn't answer the exact question. c) Surgical exploration, debridement, irrigation and suture of the capsule. Justification is optimization of maintenance of testicular function (4 marks)

Pediatric Surgery

Model Answer Total 10 marks a) 1 mark The natural history of pectus carinatum is of a mild defect seen in infancy, which is stable during childhood, but then with the growth spurt of puberty, the deformity often worsens dramatically (1), drawing medical attention. b) 1 mark The chest wall is typically malleable and plastic during puberty. c) 3 marks Initially, patients are instructed to wear the brace for 23 hours daily (1) (correction phase, CP). They are evaluated every 2-3 months during this phase. After the defect is corrected to the satisfaction of the surgeon and the patient, bracing is reduced to 8-12 hours daily (1) (typically overnight) until cessation of axial skeletal growth (maintenance phase, MP). Once the patient's height is stable for 6 months, the bracing is discontinued (1). d) 1 mark Non-compliance e) 4 marks Overall, it is well tolerated (1), some reporting mild erythema at the bracing site (1), minimal pain (1), and rarely skin breakdown (1).
