All India Institute of Medical Sciences 2003 - Question Paper

1. A dead born foetus does not have:

1. Rigor mortis at birth.
2. Adipocere formation.
3.Maceration.
4. Mummification.

Ans 2/4??

2. False sense of perception without any external object or stimulus is known as:

1. Illusion.
2. Impulse.
3.Hallucination.
4. Phobia.

Ans 3

3. Species identifications is done by:

1.Neutron activation analysis (N.A.A.).
2. Precipitin test.
3. Benzidine test.
4. Spectroscopy.

Ans two -Tests for species identification are Precipitin test, Latex agglutination test, Haem-agglutination inhibition test.

4. In a suspected case of death due to poisoning where cadaveric rigidity is lasting longer than usual, it may be a case of poisoning due to:

1. Lead.
2. Arsenic.
3. Mercury.
4. Copper.
Ans 2

5. 'Whip-lash' injuries is caused due to:
1. A fall from a height.
2. Acute hyperextension of the spine.
3. A blow on top to head.
4. Acute hyper flexion of the spine.
Ans two (Ref Maheshwari page 147, CSDT eleventh ed 1206)- This injury occurs due to rear end automobile collision.The body of victim is accelerated by the impact force but the head is left behind.Sudden hyperextension followed by sudden hyperflexion occurs. It is mentioned that in mild forms only subtle hyperextension injuries zare obtained in X Ray.So hyperextension being the primary injury is most important ans.
Other ques. about Whiplash-
Characteristic feature is that Plain X ray may be normal. Radiological features suggestive of this unstable injury are
1) Widening of anterior disc space
2) Injury to facets joints, pedicle or lamina
3) Avulsion fractures of anterior vertebral body
4) Retropharyngeal swelling / Fracture of posterior facet.Reversal of cervical lordosis suggests damage to posterior facets and manifests as S Shaped (swan neck deformity)Kyphosis seen most often at C4-C5, C5-C6 levels.

6. All of the subsequent form radiolucent stones except:
1. Xanthine.
2. Cysteine.
3. Allopurinol.
4. Orotic acid.

Ans 2. Radio-opaque stone are Struvite, cysteine, oxlate. Radiolucent are Xanthine, uric acid and uric acid. Allopurinol stones do not exist as such but ¬ Allopurinol may lead to xanthine stones.

7. A young female presents with history of dyspnoea on exertion. On examination, she has wide, fixed split of S2 with ejection systolic murmur (III/VI) in left 2nd intercostals space. Her EKG indicates left axis deviation. The most probable diagnosis is :
1. Total anomalous pulmonary venous drainge.
2. Tricuspid atresia.
3. Ostium primum atrial septal defect.
