NEET-PG 2023 - Forensic Medicine PYQs Practice Questions

Q: A farmer was sleeping in the field, and he felt a sting on his leg. He saw something moving away quickly. He then got drowsy and was taken to the hospital. He developed pain around the site and continued to bleed profusely from the wound site. The wound became red with blisters. Which of the following is the most likely cause?

Viper bite. ***Viper bite*** - **Viper venom** is predominantly **hemotoxic**, causing local tissue damage (pain, redness, blistering, bleeding) and systemic effects like **coagulopathy**, leading to profuse bleeding [1]. - The rapid onset of drowsiness, local pain, bleeding, and blistering are classic signs of **viper envenomation** [1]. *Cobra bite* - **Cobra venom** is primarily **neurotoxic**, leading to **flaccid paralysis**, ptosis, and respiratory failure, rather than significant local tissue destruction or profuse bleeding [1]. - While local swelling and pain may occur, extensive blistering and significant bleeding are less characteristic compared to viper bites [1]. *Wasp sting* - A **wasp sting** causes localized pain, swelling, and redness, and may lead to an **anaphylactic reaction** in sensitive individuals [2]. - It does not typically cause profuse, prolonged bleeding or extensive blistering at the wound site as seen here [2]. *Scorpion sting* - **Scorpion stings** typically cause intense localized pain, paresthesias, and sometimes systemic symptoms like hypertension, tachycardia, and neurological effects [3]. - They do not typically cause widespread **hemorrhagic symptoms** or significant local blistering and extensive bleeding as described [3].

Q: In which condition is postmortem caloricity observed?

Septicemia. ***Septicemia*** - **Postmortem caloricity** (a rise in body temperature after death) is a characteristic finding in cases of **septicemia** due to ongoing bacterial activity and metabolic processes that continue for a short period post-mortem. - The bacterial activity in septicemia continues to generate heat, leading to a transient increase in core body temperature before it eventually falls to ambient levels. - **Note:** Other conditions causing postmortem caloricity include heat stroke, cholera, tetanus, and certain poisonings (e.g., strychnine), but among the given options, **septicemia is the correct answer**. *Massive hemorrhage* - **Massive hemorrhage** typically causes a significant drop in body temperature before death due to volume loss and circulatory collapse, and this hypothermia usually continues after death. - It does not involve conditions that would lead to a postmortem rise in temperature; rather, it promotes **algor mortis** (cooling of the body). *Cyanide poisoning* - **Cyanide poisoning** inhibits cellular respiration and energy production, leading to rapid tissue anoxia and cellular death. - It does not involve a process that would generate heat post-mortem; instead, it causes rapid cessation of metabolic heat production and normal cooling follows. *Corrosive poisoning* - **Corrosive poisoning** causes local tissue damage and systemic effects that can lead to shock and hypothermia, but it does not generally cause postmortem caloricity. - The primary effects are on tissue destruction and organ failure, which would not result in postmortem heat generation.

Q: Method of autopsy in which organs of various systems are removed en masse:

Lettulle. ***Lettulle*** - The **Lettulle method** (or en masse method) involves the removal of organs in large blocks or as a single unit, which helps preserve anatomical relationships. - This technique is particularly useful for studying the **interrelationships between organs** and the spread of disease involving multiple systems. *Virchow* - The **Virchow method** involves the individual removal of each organ, which allows for detailed examination of each organ separately. - This method is straightforward but can disrupt the **anatomical relationships** between organs. *Rokitansky* - The **Rokitansky method** involves *in situ* dissection of organs, with the organs remaining largely in the body during dissection. - This technique is valued for maintaining the **topographical integrity** of organ systems within the body cavity. *Ghon* - The **Ghon method** is a modified block dissection method, focusing on the removal of specific organ blocks. - This often includes the **thoracic and abdominal organs** together, maintaining their anatomical connections.
