Autoerotic Asphyxia Indian Medical PG Practice Questions and MCQs
Question 1: A 6-year-old child who does not communicate well, has slow mental and physical growth, does not interact with people, has limited interests, and becomes easily agitated if disturbed, is diagnosed with which of the following?
- A. Hyperkinetic child
- B. Autistic Disorder (Correct Answer)
- C. Mixed Receptive-Expressive Language Disorder
- D. Attention Deficit Disorder
Explanation: ***Autistic Disorder*** - The constellation of symptoms including **poor communication**, **limited social interaction**, **restricted interests**, and **agitation upon disturbance** are hallmark features of **Autistic Disorder**. - **Slow mental and physical growth** can be associated, though not a diagnostic criterion, further supporting a pervasive developmental disorder. *Hyperkinetic child* - This term is often used synonymously with **Attention-Deficit/Hyperactivity Disorder (ADHD)**, which primarily involves issues with **inattention, hyperactivity, and impulsivity**. - While agitation can occur, the central features of **social and communication deficits** and **restricted interests** are not typical of hyperkinetic disorder. *Attention Deficit Disorder* - **Attention Deficit Disorder (ADD)**, now often referred to as **ADHD predominantly inattentive presentation**, is characterized by difficulties with **focus, organization, and attention**. - It does not typically present with severe deficits in **social interaction**, **communication**, or the presence of **restricted, repetitive behaviors** as described. *Mixed Receptive -Expressive Language Disorder* - This disorder is specifically characterized by difficulties in both **understanding (receptive)** and **producing (expressive) language**. - While the child does not communicate well, the additional symptoms of **poor social interaction**, **limited interests**, and **agitation to change** are not explained solely by a language disorder.
Question 2: During autopsy of a fetal death case, what is the correct order of examination to differentiate between live birth and stillbirth?
- A. Thorax > head > abdomen
- B. Abdomen > thorax > head
- C. Thorax > abdomen > head
- D. Head > thorax > abdomen (Correct Answer)
Explanation: ***Head > thorax > abdomen*** - The **head** is examined first to preserve delicate structures and avoid artifactual changes that could obscure signs of **intrauterine pathology** or **trauma** related to birth. - After the head, the **thorax** is examined to assess the lungs for signs of **air insufflation** (indicating respiration) and the presence of **congenital anomalies** or injuries. *Thorax > head > abdomen* - Examining the **thorax** before the head may introduce artifacts to the head, such as **hemorrhage** or **tissue distortion**, compromising the investigation of **cephalic injuries** or malformations crucial for distinguishing **live birth** from **stillbirth**. - **Head injuries** or **intracranial bleeds** are often critical in determining the mode of delivery or potential trauma, so their undisturbed assessment is prioritized. *Abdomen > thorax > head* - Beginning with the **abdomen** risks significant disruption to the **thoracic** and **cephalic** structures as a consequence of handling and evisceration, potentially obscuring vital evidence of **respiration** or **birth trauma**. - The integrity of the **head** and **thorax** is paramount for identifying subtle macroscopic and microscopic findings that definitively point to a **live birth**, such as **pulmonary aeration** or **intracranial hemorrhages**. *Thorax > abdomen > head* - This sequence is suboptimal because starting with the **thorax** and then the **abdomen** still leaves the **head** vulnerable to post-mortem changes and handling artifacts due to the initial dissections. - Critical evidence in the head pertaining to **neurological insult** or **traumatic injury** during birth might be overlooked or misinterpreted if not examined early in a pristine state.
Question 3: A 35-year-old male is brought to the psychiatric emergency department after being arrested for attempting sexual acts with a deceased body in a morgue where he worked as a janitor. He admits to having recurrent sexual fantasies involving corpses for the past 3 years. This condition is identified as:
- A. Necrophilia (Correct Answer)
- B. Lust murder
- C. Bobbit syndrome
- D. Mutual masturbation
Explanation: ***Necrophilia*** - **Necrophilia** is a paraphilia characterized by a sexual attraction to or sexual acts with corpses. - The patient's actions and recurrent fantasies involving deceased bodies directly match the diagnostic criteria for this condition. *Lust murder* - **Lust murder** involves killing someone for sexual gratification, often accompanied by sexual mutilation. - While it has a sexual component and involves a body, it specifically refers to the act of murder itself, which is not described in this scenario. *Bobbit syndrome* - **Bobbit syndrome** refers to the self-mutilation or forced mutilation of the penis, often in the context of domestic violence or extreme emotional distress. - This condition is entirely unrelated to sexual attraction towards corpses. *Mutual masturbation* - **Mutual masturbation** is a consensual sexual activity between two or more living individuals where each person stimulates their own genitals, often in the presence of others. - This option describes a consensual act between living partners and has no relevance to the patient's actions or fantasies involving deceased bodies.
Question 4: Burking includes:
- A. Ligature strangulation
- B. Drowning mechanism
- C. Hanging technique
- D. Chest compression and airway obstruction (Correct Answer)
Explanation: ***Chest compression and airway obstruction*** - Burking is a **homicidal method** of suffocation that involves **covering the mouth and nose** (airway obstruction) combined with **compressing the chest or abdomen** to prevent breathing. - Named after **William Burke**, this technique was used to kill victims without leaving obvious signs of violence, making deaths appear natural. *Ligature strangulation* - Involves using a **cord, rope, or similar object** around the neck to compress blood vessels and/or airway. - Leaves characteristic **ligature marks** on the neck, which burking aims to avoid by using manual compression instead. *Drowning mechanism* - Involves **submersion in liquid** causing respiratory impairment and asphyxia. - Completely different mechanism from burking, which involves **manual suffocation** on dry land without water involvement. *Hanging technique* - Hanging involves **suspension of the body by the neck**, causing death through compression of neck structures. - This is completely different from burking and leaves distinct **hanging marks** on the neck, which burking specifically avoids.
Question 5: A woman died within 5 years of marriage under suspicious circumstances. Her parents complained that her in-laws used to frequently demand dowry. Under which of the following sections can a magistrate authorize an autopsy of the case?
- A. Section 302 IPC
- B. Section 174 Cr Pc
- C. Section 304 IPC
- D. Section 176 Cr Pc (Correct Answer)
Explanation: ***Section 176 Cr PC*** - This section empowers a **Magistrate to hold an inquiry into the cause of death** in cases of suspicious circumstances, including deaths within seven years of marriage where dowry harassment is alleged. - The magistrate can **order a post-mortem examination** or even a second post-mortem if there are doubts about the initial findings, making it the appropriate section for **magisterial authorization** of autopsy. - In dowry death cases, Section 176 provides judicial oversight and ensures an independent inquiry beyond police investigation. *Section 174 Cr PC* - This section deals with **police inquiry** and report on suicide and suspicious deaths, empowering the **police officer** (not magistrate) to investigate and order an autopsy. - While Section 174 is used for initial police investigation in suspicious deaths, the question specifically asks about **magistrate authorization**, which falls under Section 176. - Section 174 is the procedural provision for police-initiated investigation, whereas magisterial inquiry requires Section 176. *Section 304 IPC* - This section pertains to **punishment for culpable homicide not amounting to murder**. It is a substantive penal provision, not a procedural law. - It deals with the legal consequence of an act after investigation and trial, not with the investigative procedure for conducting an autopsy. - Charges under Section 304 IPC may result from findings after the autopsy, but it doesn't authorize the autopsy itself. *Section 302 IPC* - This section specifies the **punishment for murder**. Like Section 304 IPC, it is substantive criminal law defining a crime and its penalty. - It would be invoked *after* the investigation reveals evidence of murder, not during the initial phase of ordering an autopsy for a suspicious death. - An autopsy authorized under Cr PC sections might lead to charges under Section 302 IPC, but it doesn't authorize the autopsy procedure.
Question 6: Maceration is seen in death of?
- A. 70 year old man with minimal adipose tissue
- B. Dead born fetus (Correct Answer)
- C. 40 year old man died due to sepsis
- D. 25 year old man died due to drowning in fresh water
Explanation: ***Dead born fetus*** - **Maceration** is a characteristic post-mortem change seen in a **fetus that dies in utero** and remains within the amniotic fluid. - The skin becomes soft, wrinkled, and peeled due to prolonged exposure to **amniotic fluid**, giving it a parboiled appearance. *70 year old man with minimal adipose tissue* - **Maceration** is a process that primarily affects fetal tissue within a fluid-filled environment (amniotic fluid) and is not typically observed in post-mortem changes in adults. - In adults, the body undergoes decomposition processes like **autolysis** and **putrefaction**, not maceration of this type. *40 year old man died due to sepsis* - Death due to **sepsis** in an adult would lead to general decomposition changes, potentially accelerated by infection, but not **maceration** as seen in a dead born fetus. - The body would undergo **autolysis** and **putrefaction** with characteristic signs like discolouration and gas formation, rather than skin peeling from fluid exposure. *25 year old man died due to drowning in fresh water* - While prolonged immersion in water can cause *skin wrinkling* (washerwoman's hands/feet), this is a superficial change and not the extensive **maceration** with skin peeling seen in a dead born fetus. - The overall decomposition and post-mortem changes would follow those of a submerged adult body, including **adipocere formation** under specific conditions, not fetal maceration.
Question 7: Cause of death for drowning in cold water:
- A. Inability to breathe (asphyxia) (Correct Answer)
- B. Loss of consciousness due to hypoxia
- C. Cardiac arrest due to vagal inhibition
- D. Cardiac arrest due to ventricular fibrillation
Explanation: ***Inability to breathe (asphyxia)*** - Drowning fundamentally involves **inhalation of water** into the airway, which prevents gas exchange in the lungs, leading to **asphyxia**. - In cold water, the initial gasp reflex can lead to rapid aspiration of water, causing immediate **laryngospasm** and closure of the airway, resulting in inability to breathe. - Asphyxia remains the **most common mechanism** across all types of drowning, including cold water cases. *Loss of consciousness due to hypoxia* - While **hypoxia** certainly occurs in drowning due to lack of gas exchange, loss of consciousness is a *consequence* of prolonged asphyxia, not the primary cause of death. - The immediate cause of death is the inability to oxygenate the blood due to water filling the lungs or severe laryngospasm. *Cardiac arrest due to vagal inhibition* - **Vagal inhibition** (also called **hydrocution** or **immersion syndrome**) is an important mechanism specifically in **cold water drowning**. - Sudden immersion in cold water can trigger massive vagal stimulation leading to immediate cardiac arrest (often asystole) before significant water aspiration occurs. - However, this mechanism occurs in a **minority of cold water drowning cases**, while asphyxia remains the predominant cause of death overall. *Cardiac arrest due to ventricular fibrillation* - **Ventricular fibrillation** can be a terminal event in drowning, often secondary to severe hypoxia and hypothermia, but it is usually not the initial or primary cause of death. - The cessation of breathing and subsequent lack of oxygen directly lead to organ failure, including cardiac dysrhythmias, rather than ventricular fibrillation being the independent initial event.
Question 8: The friend and victim had alcohol and got into an argument over a common girlfriend, following which the friend kills the victim by sitting on his chest and covering his nose and mouth. This is an example of?
- A. Gagging
- B. Smothering (Correct Answer)
- C. Choking
- D. Throttling
Explanation: ***Smothering*** - This scenario describes **manual obstruction** of the mouth and nose, preventing air entry without external neck compression. - The act of sitting on the chest further restricts respiratory movements, contributing to **asphyxia**. *Gagging* - Gagging refers to the obstruction of the **oral cavity** due to material placed inside the mouth, typically to prevent speaking or crying out. - While it can contribute to asphyxia, the primary mechanism described here involves external covering of both nose and mouth. *Choking* - Choking involves the **internal obstruction** of the airway, usually by a foreign body lodged in the pharynx or larynx. - This scenario explicitly details external occlusion of the respiratory orifices, not internal blockage. *Throttling* - Throttling is a form of **manual strangulation** that involves direct compression of the neck by hands or forearm. - The description of covering the nose and mouth rather than compressing the neck rules out throttling.
Question 9: In typical hanging, knot is placed at:
- A. Chin
- B. Right side of mandible
- C. Occiput (Correct Answer)
- D. Left side of mandible
Explanation: ***Occiput*** - In **typical hanging** (complete suspension of the body), the knot is usually placed at the **occipital region** (nape of the neck/back of the head). - This positioning results in an **oblique ligature mark** that is higher posteriorly and **typical of suicidal hanging**. - Death occurs primarily due to **compression of neck vessels** (carotid arteries and jugular veins), leading to **cerebral anoxia**, and **vagal nerve stimulation** causing cardiac arrest. - The **occiput position** distinguishes typical hanging from atypical variants. *Chin* - If the knot is placed at the chin (anterior position), this is **not characteristic of typical hanging**. - This position would cause primarily **airway compression** but is uncommon in practice. - Anterior positioning is rarely seen in complete suspension cases. *Right side of mandible* - Placing the knot on the **lateral side** of the mandible (right or left) is characteristic of **atypical hanging**. - This results in an **oblique ligature mark** higher on the side of the knot. - In atypical hanging, the body may be **partially suspended** or in various positions (sitting, kneeling, lying). - Death occurs through similar mechanisms but may be slower due to incomplete vascular compression. *Left side of mandible* - Similar to placement on the right side, a knot on the left side of the mandible indicates **atypical hanging**. - The **lateral position** of the knot (either side) is the key distinguishing feature from typical hanging where the knot is posterior. - Atypical hanging is still fatal through neck vessel compression and vagal stimulation, though the presentation differs from typical cases.
Question 10: On postmortem examination, contusion of neck muscles is seen along with fracture of hyoid bone. The most probable cause of death is:
- A. Hanging
- B. Burking
- C. Throttling (Correct Answer)
- D. Smothering
Explanation: ***Throttling*** - **Manual strangulation** (throttling) causes direct compression of the neck with fingers and thumbs, leading to **bilateral contusion of neck muscles** and **fracture of the hyoid bone** due to sustained gripping force. - The combination of **deep muscle contusions** (especially in strap muscles, sternomastoid) with hyoid fracture is **highly characteristic** of manual strangulation, as the direct manual force applied causes crushing injury to both soft tissues and cartilaginous/bony structures. - Additional findings often include **fingernail marks/abrasions** on the neck, bruising corresponding to finger positions, and fractures of thyroid cartilage. - This pattern is **strongly suggestive of homicide** given the force and duration required. *Hanging* - In hanging, the force is applied through a **ligature** that creates a characteristic **oblique ligature mark** (typically rising toward the point of suspension). - While hyoid bone fractures **can occur** in hanging (especially in elderly individuals with ossified hyoid or in judicial hanging), they are **less common** (15-30% of cases) compared to manual strangulation (30-50% of cases). - **Deep bilateral neck muscle contusions are atypical** in hanging; when present, muscle injuries are usually **unilateral** and correspond to the side of the knot or are superficial. - The ligature mark and pattern of neck injuries distinguish hanging from manual strangulation. *Burking* - **Burking** involves compression of the chest and abdomen to prevent respiratory movements, combined with covering the mouth and nose. - This method causes **asphyxia** by impairing chest wall expansion and occluding airways, **without direct neck compression**. - Neck injuries like deep muscle contusions and hyoid fracture are **not characteristic** of burking; findings are primarily thoracic petechiae and signs of chest/abdominal compression. *Smothering* - **Smothering** involves blocking the nose and mouth (with hand, pillow, or other soft material) to prevent air entry. - This causes **suffocation without neck trauma**; typical findings include petechiae around eyes and face, oral/nasal bleeding. - **Absence of neck injuries** (no muscle contusions, no hyoid fracture) distinguishes smothering from strangulation methods.
