2) Aluminum phosphide poisoning - all true except
a. Sub-endocardial infarcts
b. Produces phosphine gas
c. Oesophageal stricture
d. Cyt. A oxidase inhibitor
Explanation: Aluminum phosphide ( Celphos) toxicity appears to be due to release of PHOSPHINE on contact with moisture . This phosphine gas due to non competitive inhibition of cytochrome oxidase system of mitochondria or damage by free radicals causes global hypoxia.Significant inhibition of cytochrome-c oxidase activity can be found in ALP-poisoned patients
Organs with the greatest oxygen requirements appear to be especially sensitive to phosphine, including the brain, kidneys, heart, and liver. Phosphine has a characteristic odor described as "decaying fish. Cardiac dysrhythmias probably secondary to electrolyte imbalances have been described in sub-lethal acute exposures. Transient atrial fibrillation and sub-endocardial infarction, adrenocortical injury with elevated serum cortisol levels have been reported.
3) True about subendocardial hemorrhage are all except
a.) May be seen after head injury
b.) Involves RV WALL
c.) Continuous pattern
d.) Flame shaped hemorrhages
Explanation: Subendocardial hemorrhage are found after intracranial hemorrhage following injury due to trauma, suddenly hypotension following any bleeding problems, obstetric complication, toxic poisoning particularly with iron, arsenic, cocaine and cerebral hemorrhage strokes. SEH involves left ventricular walls, flame shaped confluent, non-petechial and continuous. SEH are signs of agonal vital events. (Page 295 Forensic Pathology Reviews: Michael Tsokos)

a) Racoon eyes seen in subgaleal hemorrhage
b) Depressed skull # is always over the immediate area of impact of brain
c) corticocavernous fistual occur in base skull #
d) post traumatic epilepsy seen in 15%
Rule of Thumb* "Always" in choices is most of the time correct answer!
*apply at your own risk!
o BATTLE SIGN- Bruising behind ear at mastoid region, due to petrous temporal bone# (middle fossa #)
o LIGHT HOUSE SIGN--- seeping out of secretions in acute OTITIS media
o RACOON SIGN-Indicate subgaleal hemorrhage,and not necessarly base of skull #
o STANKIEWICK'S SIGN - indicate orbital injury during FESS. fat protrude in to nasl cavity on compression of eye ball from ouside
o TEA POT SIGN is seen in CSF rhinorrhoea.
