Q

Definition Senile myocardium
Findings
Histology

A
  • myocardial degeneration due to senility
  • findings: heart is brown and flabby soft. The coronary vessels are torturous

17
Q

Common sites of cerebral bleeding in children

A
  • bifurcation of middle cerebral artery and post comm artery
  • bifurcation of basilar arteries
  • middle cerebral artery
  • ant comm artery
18
Q

Predisposing fx of pulm thromboembolism

A
  • trauma
  • surgery
  • bed ridden
  • immobility
19
Q

Findings of epilepsy

A
  • tongue bite marks, patchy myocardial fibrosis
20
Q

How bronchial asthma cause death and findings

A
  • dt overuse of inhalers causing hypoxia and respiratory acidosis.
  • causing ventricular fibrillation dt theophylline and sympathomimetics

Findings: lung expanded, pale spongy lung, thick clear mucus in bronchus

21
Q

Causes of respiratory obstruction

A
  • rupture of retropharyngeal abscess (‘quincy’)
  • laryngeal obstruction in diphteria
  • laryngeal oedema from epiglottis (children)
22
Q

Causes and mechanism haemoptysis

A

Causes
- dt pulm tuberculosis and bronchial tumours (eroding large vessels)

Mechanism
- causing asphyxia or vagal inhibition (sudden flooding of larynx)

23
Q

Causes of GI haemorrhage

A
  • esophageal carcinoma
  • ruptured esophageal varices
  • gastric ulcer and peptic ulcer
  • carcinoma of stomach
24
Q

Causes of intestinal haemorrhage

A
  • haemorrhagic diathesis
  • colonic ca
  • ulcerative colitis
  • colonic polyp
25
Q

Causes of abdominal catastrophes

A
  • mesentric thrombosis and infarction
  • strangulated intestine
  • hernia (femoral and inguinal)
26
Q

Patho of PE, when is it occur

A

Virchows triad
- slowing of circulation (stasis)
- local injury to vessel wall (endothelial injury)
- increase blood coagulability (hypercoagulability)

Occur 2 weeks after trauma, range from 2-90 days
