Question 1461: Algor mortis is defined as:
- A. Hypostasis
- B. Cadaveric spasm
- C. Rigor mortis
- D. Cooling of body (Correct Answer)
Explanation: ***Cooling of body (Algor mortis)*** - **Algor mortis** specifically refers to the **post-mortem cooling** of the body until it matches the temperature of the surrounding environment. - This process is used in forensic pathology to estimate the **time of death**, as the rate of cooling is somewhat predictable under standard conditions. - The body typically cools at approximately **1-1.5°F per hour** in temperate conditions, though this varies with environmental factors. *Hypostasis* - **Hypostasis**, also known as **livor mortis** or lividity, is the **pooling of blood** in the capillaries of the skin due to gravity after circulation ceases. - This results in a discoloration of the skin, typically purplish-red, in dependent areas of the body. - It begins within 30 minutes to 2 hours after death and becomes fixed after 8-12 hours. *Cadaveric spasm* - **Cadaveric spasm** is a rare and immediate stiffening of muscles that occurs at the moment of death, without passing through the stage of primary flaccidity. - It is often associated with intense emotional stress or extreme physical exertion just before death, causing objects to be clutched firmly. - This is distinct from rigor mortis as it occurs instantaneously rather than developing gradually. *Rigor mortis* - **Rigor mortis** is the **stiffening of muscles** after death, caused by the depletion of ATP, which prevents the detachment of myosin heads from actin filaments in muscle fibers. - It typically begins 2-4 hours post-mortem, reaches maximum stiffness at 12-24 hours, and then gradually resolves after 24-48 hours as autolysis progresses.
Question 1462: Cause of death in cafe coronary:
- A. Pulmonary edema
- B. Laryngeal edema
- C. Asphyxia (Correct Answer)
- D. Cardiac arrest
Explanation: ***Asphyxia*** - Cafe coronary refers to sudden death due to **choking on food or foreign objects**, typically occurring in public places like restaurants. - The primary cause of death is **asphyxia**, resulting from the obstruction of the **larynx or trachea**, preventing air from reaching the lungs. *Pulmonary edema* - **Pulmonary edema** is an accumulation of fluid in the lungs, often due to heart failure or acute lung injury. - It is not the direct cause of death in a cafe coronary, as the primary issue is mechanical airway obstruction, not fluid overload in the lungs. *Laryngeal edema* - **Laryngeal edema** involves swelling of the larynx, which can cause airway obstruction. - While it can lead to respiratory distress, in a cafe coronary, the obstruction is typically mechanical from a foreign body, not primarily an inflammatory or allergic edema of the larynx itself. *Cardiac arrest* - While **cardiac arrest** is the ultimate event leading to death, it is a consequence of severe hypoxia caused by the airway obstruction in a cafe coronary. - The direct and initial cause of the life-threatening situation is the inability to breathe due to the blockage, leading to oxygen deprivation of the heart.
Question 1463: Victim was strangled with elbow around neck. It is called as:
- A. Mugging (Correct Answer)
- B. Throttling
- C. Burking
- D. Garrotting
Explanation: ***Mugging*** - **Mugging** (also called "yoking" or "bar arm strangle") is the forensic medicine term for strangulation using the **arm or elbow encircling the neck**. - In this technique, the assailant typically approaches from behind and applies the forearm or crook of the elbow across the victim's throat, compressing the neck structures. - This method compresses the carotid arteries and jugular veins, leading to rapid unconsciousness and potential death from cerebral hypoxia. *Throttling* - **Throttling** specifically refers to manual strangulation using the **hands (fingers and thumbs)** to compress the neck. - The assailant applies direct pressure with their fingers on the front or sides of the victim's neck. - This differs from the scenario described, which involves the elbow/arm, not the hands. *Burking* - **Burking** is a historical method of murder involving suffocation by covering the mouth and nose while applying pressure to the chest. - Named after William Burke, this method was designed to leave minimal external marks on the body. - It does not involve neck compression or strangulation. *Garrotting* - **Garrotting** is strangulation using a **ligature** (rope, wire, cloth, or cord) tightened around the neck. - This involves an instrument rather than direct body contact. - It differs from mugging, which uses the arm/elbow without any intermediate object.
Question 1464: What is the most reliable method to determine the time of death within the first 24 hours after death?
- A. Livor mortis is fixed and cannot be displaced after 8-12 hours
- B. Rigor mortis appears first in smaller muscles and progresses to larger muscles
- C. Putrefaction begins immediately after death in all environmental conditions
- D. Algor mortis using rectal temperature with standard nomograms (Correct Answer)
Explanation: ***Algor mortis using rectal temperature with standard nomograms*** - **Algor mortis** (body cooling) measured via **rectal temperature** using standardized nomograms (such as **Henssge's nomogram**) is considered the **most reliable method** for estimating time of death within the first 24 hours. - While environmental factors affect cooling rate, the use of **mathematical models and nomograms** that account for body weight, ambient temperature, and clothing make this method more **objective and reproducible** than other postmortem changes. - Provides **quantitative data** that can be standardized, unlike the more subjective assessments of rigor or livor mortis. *Rigor mortis appears first in smaller muscles and progresses to larger muscles* - **Rigor mortis** follows **Nysten's rule** (progression from smaller to larger muscles), typically appearing within 2-6 hours, peaking at 12-24 hours. - However, the **onset time is highly variable** depending on factors like ante-mortem physical activity, environmental temperature, and cause of death. - The subjective nature of assessment and **significant individual variation** make it less reliable than temperature-based methods for precise time estimation. *Livor mortis is fixed and cannot be displaced after 8-12 hours* - **Livor mortis** (postmortem lividity) becomes fixed and non-blanchable after approximately 8-12 hours. - While useful, the **wide time range** for fixation and the fact that it provides only a few discrete time points (appearance, confluence, fixation) make it less precise than continuous temperature measurements. *Putrefaction begins immediately after death in all environmental conditions* - This statement is **incorrect**. **Putrefaction** (bacterial decomposition) typically begins hours to days after death, heavily dependent on **environmental temperature** and humidity. - Putrefaction is useful for estimating time of death **beyond 24-48 hours**, not within the first 24 hours as asked in this question.
Question 1465: Cognizable offence comes under which section of CrPC? (NEET 13)
- A. 1 (a)
- B. 2 (c) (Correct Answer)
- C. 2 (b)
- D. 2 (1)
Explanation: ***Option 2 (c)*** - Section **2(c)** of the Criminal Procedure Code (CrPC) defines a **cognizable offense**. - A cognizable offense is one in which a police officer may **arrest without a warrant** and commence investigation without the permission of a magistrate. *Option 1 (a)* - This section reference is incorrect as there is no relevant definition under **Section 1(a)** that pertains to cognizable offenses. - Section 1 of CrPC deals with the **short title, extent, and commencement** of the code, not definitions. *Option 2 (b)* - Section **2(b)** of the CrPC defines "**charge**." - A charge includes any **head of a charge** when the charge contains more than one head. *Option 2 (1)* - This section reference is not a standard way of citing definitions within the CrPC (should be lowercase alphabet). - Even if interpreted as **Section 2(l)**, it defines **"non-cognizable offense"**, which is the opposite of what the question asks.
Question 1466: Police inquest is most straightforward in:
- A. Death by animals
- B. Homicidal death
- C. Suicidal death (Correct Answer)
- D. Dowry death
Explanation: ***Suicidal death*** - Suicidal deaths with clear evidence (suicide note, history of depression, consistent physical findings) are typically the **most straightforward** for police inquest among unnatural deaths. - The investigation primarily focuses on **confirming self-infliction** and ruling out foul play, which is relatively simple when circumstances are clear and consistent. - Unlike homicide, there is **no perpetrator to identify**, and unlike dowry death, there are no complex familial or legal entanglements to investigate. - The inquest becomes straightforward when evidence is consistent: method matches injuries, suicide note is present, and witness statements corroborate suicidal intent. *Death by animals* - Death by animal attacks involves **complex liability investigations** including determining provocation, owner negligence, and whether proper safety measures were in place. - Requires investigation into whether the animal was **improperly restrained**, whether the victim provoked the attack, and potential criminal/civil liability of the owner. - Scene reconstruction and expert veterinary input may be needed, making it more complex than straightforward suicide cases. *Homicidal death* - Homicidal deaths involve **intentional killing by another person**, requiring extensive investigation into motive, suspects, weapon identification, and evidence collection. - These are the **most complex inquests**, involving forensic analysis, witness interviews, crime scene reconstruction, and protracted legal proceedings. *Dowry death* - Dowry deaths under Section 304B IPC are **highly complex**, involving investigation of harassment, dowry demands, and family dynamics over an extended period. - Requires proving that death occurred within **7 years of marriage** and was connected to dowry demands, often involving multiple suspects and sensitive family investigations.

NEET-PG 2013 - Orthopaedics NEET-PG Practice Questions and MCQs
Question 1461: Most common complication of intertrochanteric fracture femur is:
- A. Malunion (Correct Answer)
- B. Nerve injury
- C. Osteoarthritis
- D. Non-union
Explanation: ***Malunion*** - **Malunion** is the most common complication of intertrochanteric fractures, particularly with unstable fracture patterns or inadequate reduction and fixation. - This typically results in leg length discrepancy, gait disturbance, and persistent pain due to abnormal alignment. *Nerve injury* - **Nerve injury** is a rare complication of intertrochanteric fractures, as the major nerves (e.g., sciatic, femoral) are not in close proximity to the fracture site. - While possible with severe trauma or surgical errors, it is not considered the most common complication. *Osteoarthritis* - **Osteoarthritis** can develop years after an intertrochanteric fracture due to altered biomechanics, but it is a long-term sequela, not an immediate or most common post-fracture complication. - Early complications like malunion or infection are more prevalent. *Non-union* - **Non-union** is relatively uncommon in intertrochanteric fractures because this area of the femur has an excellent blood supply, which promotes healing. - This complication is more frequently seen in femoral neck fractures due to their tenuous blood supply.
Pathology

NEET-PG 2013 - Pathology NEET-PG Practice Questions and MCQs
Question 1461: Virchow method of organ removal is:
- A. In situ dissection
- B. Organs removed en masse
- C. Organs removed en bloc
- D. Organs removed one by one (Correct Answer)
Explanation: ***Organs removed one by one*** - The **Virchow method** is characterized by the sequential removal of **individual organs** through a systematic dissection. - This technique allows for detailed inspection and measurement of each organ independently, which can be useful for identifying specific pathologies confined to single structures. *In situ dissection* - This method involves dissecting and examining organs **within the body cavity before removal**, which is not the primary characteristic of the Virchow method. - While some dissection occurs *in situ*, the essential principle of Virchow's method is the **separate extraction** of organs. *Organs removed en masse* - This describes the **Ghon method**, where organs are removed in three blocks (thoracic, abdominal-gastrointestinal, and genitourinary) and then dissected. - This method aims to preserve anatomical relationships between organs, which contrasts with the single-organ focus of the Virchow method. *Organs removed en bloc* - This term generally refers to removing organs in **several blocks or groups** (similar to the Ghon method), maintaining some anatomical connections. - It does not involve the individual removal of each organ, which is the defining feature of the Virchow technique.

NEET-PG 2013 - Psychiatry NEET-PG Practice Questions and MCQs
Question 1461: All are first rank symptoms of schizophrenia, except:
- A. Audible thoughts
- B. Thought broadcasting
- C. Voice arguing or discussing or both
- D. Perplexity (Correct Answer)
Explanation: ***Perplexity*** - **Perplexity** is a state of severe confusion, bewilderment, or puzzlement, which can be seen in various psychiatric conditions but is not specifically classified as a **first-rank symptom of schizophrenia** by Kurt Schneider. - While it may be present in schizophrenia, it is a non-specific symptom, meaning it can occur in conditions other than schizophrenia. *Audible thoughts* - **Audible thoughts** (Gedankenlautwerden in German) refers to the patient hearing their own thoughts spoken aloud, often as if by another voice. - This is considered a **first-rank symptom** as described by Kurt Schneider, highly indicative of schizophrenia. *Thought broadcasting* - **Thought broadcasting** is the delusional belief that one's thoughts are escaping from their mind and are somehow accessible to others. - This symptom is also a **first-rank symptom** of schizophrenia according to Schneider's criteria. *Voice arguing or discussing or both* - **Voices arguing or discussing** are a specific type of auditory hallucination where two or more voices are perceived to be talking to each other, often about the patient. - This phenomenon is considered a classic **first-rank symptom** of schizophrenia.
Question 1462: Quod hanc means:
- A. Impotent due to psychological factors
- B. Impotent due to physical factors
- C. Impotent in specific situations
- D. Impotent towards a particular woman (Correct Answer)
Explanation: ***Impotent towards a particular woman*** - The Latin phrase "**Quod hanc**" translates to "towards this woman." - In a medical or medico-legal context, particularly when discussing impotence or fertility, it refers to a situation where a man is **impotent only in relation to a specific woman** or partner, but not with others. [1] *Impotent due to psychological factors* - While psychological factors can cause situational impotence, "Quod hanc" specifically describes an impotence directed **"towards this woman,"** rather than broadly psychological. - This option is broader than the precise meaning of the Latin phrase, which highlights the **specificity of the partner**. *Impotent due to physical factors* - "Quod hanc" has no direct implication about the underlying cause being physical; it solely points to the **target of the impotence**. - Physical impotence would generally mean an inability to achieve erection with **any partner**, which contradicts the specific nature implied by "hanc." *Impotent in specific situations* - This is a general term for **situational impotence**, which could include performance anxiety or stress. [1] - "Quod hanc" is a **more specific sub-category** of situational impotence, precisely indicating that the impotence is directed at "this woman."
