Infanticide Methods Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Infanticide Methods. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Infanticide Methods Indian Medical PG Question 1: Further investigation is essential in a newborn with which of the following conditions?
- A. Vaginal bleed
- B. Subconjunctival hemorrhage
- C. Lens opacity (Correct Answer)
- D. Erythema toxicum
Infanticide Methods Explanation: ***Lens opacity***
- A **lens opacity** in a newborn suggests congenital **cataracts**, which can lead to permanent vision impairment if not identified and treated early.
- **Investigation is essential** to identify underlying causes such as **TORCH infections** (Toxoplasmosis, Rubella, CMV, HSV), **metabolic disorders** (galactosemia, Lowe syndrome), **genetic syndromes**, or **chromosomal abnormalities**.
- Early detection and management are crucial to prevent **amblyopia** (lazy eye) and optimize visual development during the **critical period** of visual maturation.
- Investigations include: TORCH titers, urine for reducing substances, metabolic screening, and genetic evaluation.
*Erythema toxicum*
- This is a common, **benign newborn rash** characterized by blotchy red macules and papules with central vesicles or pustules.
- It typically resolves spontaneously within days to a few weeks and requires **no specific investigation or treatment**.
*Vaginal bleed*
- A small amount of **vaginal bleeding** in female newborns is usually due to the temporary withdrawal of maternal hormones (e.g., estrogen) after birth.
- This is a **physiologic response** and generally self-resolves, requiring no further investigation unless excessive or prolonged.
*Subconjunctival hemorrhage*
- This occurs due to the rupture of tiny blood vessels in the eye during the birthing process, often associated with **vaginal delivery**.
- It is a **benign condition** that resolves on its own within a couple of weeks and does not affect vision.
Infanticide Methods Indian Medical PG Question 2: White lathery froth is seen in deaths due to:
- A. Drowning (Correct Answer)
- B. Hanging
- C. Mineral acid poisoning
- D. Organophosphate poisoning
Infanticide Methods Explanation: ***Drowning***
- The characteristic **white lathery froth** (called **foam cone** or **mushroom froth**) appears at the mouth and nostrils due to the mixing of water, mucus, and air in the airways, often churned during respiratory efforts.
- This froth is a strong indicator of **drowning**, although not always definitive of its cause.
*Hanging*
- Deaths due to hanging typically result from **asphyxia** due to airway obstruction or cerebral ischemia due to carotid artery compression, and do not usually involve froth formation.
- While sometimes there may be some oral secretions, it is not the classic lathery, persistent foam seen in drowning.
*Organophosphate poisoning*
- Organophosphate poisoning causes **cholinergic crisis**, leading to excessive secretions like salivation, lacrimation, and bronchorrhea.
- The secretions are usually watery to frothy, but not typically the voluminous, stable, white lathery froth seen in drowning.
*Mineral acid poisoning*
- Ingestion of mineral acids causes severe **corrosion** and **necrosis** of the gastrointestinal tract and airways, leading to difficulty breathing and potential laryngeal edema.
- Froth is not a characteristic finding; instead, there may be **burns** around the mouth and pharynx, and signs of internal visceral damage.
Infanticide Methods Indian Medical PG Question 3: Killing of a 6 months old child by parents is known as -
- A. Neonatal homicide
- B. Genocide
- C. Infanticide (Correct Answer)
- D. Abortion
Infanticide Methods Explanation: ***Infanticide***
- This term specifically refers to the killing of an **infant** (child under 1 year of age), typically by a parent.
- In **forensic medicine**, infanticide is legally defined as the intentional killing of a child within **12 months of birth**.
- Often committed by the mother during the first year of life, sometimes in the context of **puerperal psychosis** or postpartum mental health issues.
- Under **Indian Penal Code Section 315**, specific provisions exist for infanticide, with different penalties compared to murder.
*Neonatal homicide*
- Refers to the killing of a **neonate** (newborn within the first **28 days** of life).
- A 6-month-old child is well beyond the neonatal period, making this term inappropriate.
- Also called **neonaticide** in forensic literature.
*Genocide*
- Refers to the systematic and intentional destruction of a **racial, ethnic, national, or religious group**.
- Involves **mass killing** of people, not an individual act.
- Completely different from the killing of a single child by parents.
*Abortion*
- Medical or surgical termination of **pregnancy before viability** (typically before 20-24 weeks of gestation).
- Involves termination of a **fetus in utero**, not a child who has already been born.
- A 6-month-old child is a live-born infant, making this term completely inapplicable.
Infanticide Methods Indian Medical PG Question 4: Disputed maternity can be solved by using the following tests, EXCEPT:
- A. Blood grouping
- B. HLA typing
- C. DNA fingerprinting
- D. Precipitin test (Correct Answer)
Infanticide Methods Explanation: ***Precipitin test***
- The **precipitin test** is used to determine the origin of a **blood sample**, specifically whether it is **human or animal blood**, by detecting species-specific proteins. It is not used for assessing maternity.
- This test is primarily employed in **forensic serology** to differentiate between blood from different animal species, making it irrelevant for paternity or maternity disputes.
*Blood grouping*
- **Blood grouping** (e.g., ABO and Rh systems) can be used to **exclude paternity or maternity** by comparing the blood types of the child, mother, and alleged father.
- If the child's blood type is incompatible with the alleged parents based on Mendelian inheritance, one or both can be excluded.
*HLA typing*
- **HLA typing** (Human Leukocyte Antigen) is a more powerful genetic marker system than ABO/Rh for determining paternity or maternity.
- It involves analyzing highly polymorphic genes on chromosome 6 that encode cell surface proteins, providing a more definitive means of **inclusion or exclusion**.
*DNA fingerprinting*
- **DNA fingerprinting** (also known as **DNA profiling**) is the **most accurate and widely accepted method** for resolving paternity and maternity disputes.
- It analyzes highly variable regions of DNA unique to each individual, providing a statistically strong basis for **inclusion or exclusion** by comparing genetic profiles.
Infanticide Methods Indian Medical PG Question 5: Certain obligations on the part of a doctor who undertakes a postmortem examination are the following, EXCEPT:
- A. Routinely record all positive findings and important negative ones
- B. He must keep the police informed about the findings (Correct Answer)
- C. The examination should be meticulous and complete
- D. He must preserve viscera and send for toxicology examination in case of poisoning
Infanticide Methods Explanation: ***He must keep the police informed about the findings***
- This is **NOT a formal obligation** of the doctor conducting a postmortem examination.
- The doctor's primary duty is to conduct a thorough, objective examination and prepare a **formal postmortem report** that is submitted to the authority who requisitioned the examination (magistrate/police as per CrPC Section 174).
- While findings may eventually reach the police through the official report, there is **no obligation to informally update or keep police informed** during the examination process.
- The doctor's role is that of an **independent expert witness** to the court, not an investigative assistant to the police.
- Maintaining independence and objectivity requires the doctor to document findings formally rather than providing ongoing informal updates to investigating officers.
*Routinely record all positive findings and important negative ones*
- This IS a **fundamental obligation** for any doctor performing a postmortem examination.
- Both positive findings (pathological changes, injuries) and significant negative findings (absence of expected pathology) must be documented to provide a comprehensive and accurate record.
- This meticulous documentation ensures the **integrity, reliability, and legal validity** of the postmortem examination and its conclusions.
*The examination should be meticulous and complete*
- This IS a **professional, ethical, and legal obligation** for any doctor undertaking a postmortem examination.
- A systematic and thorough examination of all body systems is essential to accurately determine the cause of death and identify all relevant findings.
- Incomplete examinations can lead to **missed diagnoses and miscarriage of justice** in medico-legal cases.
*He must preserve viscera and send for toxicology examination in case of poisoning*
- This IS a **crucial obligation** when poisoning is suspected or cannot be ruled out based on the postmortem findings.
- Relevant viscera (liver, kidney, stomach contents) and bodily fluids (blood, urine) must be preserved in appropriate containers for subsequent toxicological analysis.
- This step is **essential to confirm or exclude toxicological involvement** in the death and is a standard protocol in medico-legal postmortem examinations as per established guidelines.
Infanticide Methods Indian Medical PG Question 6: Which of the following is a characteristic feature of Battered Baby Syndrome (Non-Accidental Injury)?
- A. Stab injury
- B. Firearm injury
- C. Bruises of varying ages (Correct Answer)
- D. None of the options
Infanticide Methods Explanation: ***Bruises of varying ages***
- The presence of bruises at **different stages of healing** is a hallmark indicator of **non-accidental trauma** or Battered Baby Syndrome, as it suggests repeated injuries occurring over time rather than a single incident.
- **Forensic significance**: Fresh bruises (red/purple) alongside older bruises (yellow/green/brown) indicate multiple episodes of trauma, which is inconsistent with the caregiver's explanation of a single accidental event.
- Other classic features include fractures (especially metaphyseal/corner fractures, rib fractures), subdural hematomas, retinal hemorrhages, and injuries in protected body areas.
*Stab injury*
- While a stab injury represents severe trauma requiring forensic investigation, it is **not characteristic** of the typical presentation pattern of Battered Baby Syndrome.
- Stab wounds indicate a specific violent act rather than the pattern of **repeated blunt force trauma** that defines the syndrome.
- Battered Baby Syndrome classically involves injuries from shaking, hitting, or blunt trauma rather than penetrating injuries.
*Firearm injury*
- A firearm injury is a distinct acute traumatic event that does not represent the **chronic, repetitive abuse pattern** seen in Battered Baby Syndrome.
- Such injuries are typically isolated incidents rather than part of ongoing physical abuse with varied injury ages.
- The syndrome is characterized by multiple injuries at different healing stages from repeated episodes, not single penetrating trauma.
*None of the options*
- This option is incorrect because "bruises of varying ages" is a **well-established forensic indicator** for diagnosing Battered Baby Syndrome in medical literature and practice.
- The presence of injuries at multiple stages of healing is one of the most important diagnostic features that raises suspicion for non-accidental injury in pediatric forensic medicine.
Infanticide Methods Indian Medical PG Question 7: Best criterion for determining live birth in suspected infanticide cases?
- A. Presence of milk or food in stomach
- B. Evidence of external injuries
- C. Examination of umbilical cord changes
- D. Hydrostatic test (lung float test) (Correct Answer)
Infanticide Methods Explanation: ***Hydrostatic test (lung float test)***
- The **hydrostatic test**, also known as the **lung float test**, is considered the most reliable criterion in forensic pathology for determining if an infant was born alive.
- A positive result (lungs float in water) indicates that the infant took at least one breath, suggesting **live birth**, as fetal lungs are solid and sink.
*Presence of milk or food in stomach*
- While the presence of milk or food indicates a period of survival after birth, it doesn't definitively prove **live birth** over stillbirth if the infant was fed immediately after a perimortem event.
- It also doesn't provide information about **respiration**, which is a key indicator of live birth.
*Evidence of external injuries*
- **External injuries** may indicate foul play or neglect, but they do not confirm that the infant was born alive.
- An infant could be **stillborn** and then subjected to injuries, or injuries could occur post-mortem.
*Examination of umbilical cord changes*
- **Umbilical cord changes**, such as desiccation or mummification, indicate the passage of time after birth but do not differentiate between **live birth** and **stillbirth**.
- These changes can occur even if the infant was stillborn, especially if there was an attempt to cut and tie the cord.
Infanticide Methods Indian Medical PG Question 8: A female was found dead in her bedroom. The room was not locked from inside. Her blood alcohol value was found to be 350 mg/dL. The picture taken at the post mortem is shown below. The diagnosis is? (AIIMS Nov 2018, AIIMS Nov 2017)
- A. Traumatic asphyxia
- B. Throttling (Correct Answer)
- C. Café coronary
- D. Bansdola
Infanticide Methods Explanation: ***Throttling***
- The autopsy image shows extensive **internal hemorrhage** and disruption of neck structures, consistent with significant compressive force applied to the neck by hands, as seen in **throttling**.
- **Throttling** (manual strangulation) causes deep internal injuries including fractured **hyoid bone**, damaged **thyroid cartilage**, and **strap muscle hemorrhage**, even when external marks may be minimal or absent.
- The high blood alcohol level (350 mg/dL - severe intoxication) would have impaired her ability to resist, and the unlocked room suggests **homicidal** intent rather than suicide.
- Key autopsy findings: **deep neck muscle hemorrhage**, **laryngeal fractures**, and **torn blood vessels** without a ligature pattern.
*Traumatic asphyxia*
- Traumatic asphyxia results from severe **chest/thoracic compression** leading to acute venous congestion in the head and neck region.
- Classical signs include **petechial hemorrhages** on face and conjunctivae, **cyanosis** above compression level, and relatively **intact neck structures** on autopsy.
- The severe internal neck damage shown in the autopsy image is **not characteristic** of traumatic asphyxia, which primarily affects superficial vessels due to back-pressure, not deep structural injury.
*Café coronary*
- **Café coronary** is sudden death from **food bolus aspiration** causing airway obstruction, commonly occurring in intoxicated individuals who cannot protect their airway.
- Autopsy findings would show an **obstructing food bolus in the larynx/trachea** without the extensive neck trauma and hemorrhage depicted in the image.
- No manual strangulation injuries would be present.
*Bansdola*
- **Bansdola** is a traditional method of strangulation using a **bamboo stick or rod** twisted across the neck with a rope, used historically as torture or execution.
- It causes a characteristic **linear ligature mark** with underlying soft tissue injury in a horizontal pattern across the neck.
- The autopsy findings in the image show **diffuse manual strangulation injury** rather than the specific linear pattern of ligature strangulation seen in Bansdola.
Infanticide Methods Indian Medical PG Question 9: A loop of thin string is thrown around the neck of the victim in what type of strangulation?
- A. Throttling
- B. Mugging
- C. Garrotting (Correct Answer)
- D. Hanging
Infanticide Methods Explanation: ***Garrotting***
- This involves strangulation where a **thin ligature** (string, wire, or cord) is **thrown around the neck from behind** and tightened by twisting or pulling.
- Characterized by a **horizontal ligature mark** around the neck at the level of the thyroid cartilage.
- The thin ligature causes **prominent, well-defined ligature marks** and can cause severe damage to underlying neck structures.
- Historically used as a method of execution and assassination.
*Throttling*
- **Manual strangulation** using hands, where the neck is compressed by fingers, thumbs, or palms.
- Leaves **fingernail marks, bruises, and abrasions** on the neck rather than a continuous ligature mark.
- May show **fingerprint-pattern bruising** and is typically associated with homicidal violence.
*Mugging*
- In forensic contexts, this refers to an **arm choke** or **headlock strangulation** where the forearm or elbow is placed around the victim's neck.
- Also called **brachial strangulation** or **chokehold**.
- Distinguished from garrotting by the use of the **arm as the constricting force** rather than a ligature.
*Hanging*
- Suspension of the body by a ligature around the neck where **body weight provides the constricting force**.
- Ligature mark is typically **oblique and higher on the neck**, ascending toward the point of suspension.
- Usually shows a **knot mark** and is most commonly suicidal in nature.
Infanticide Methods Indian Medical PG Question 10: The following postmortem lung specimen shows:
- A. Emphysema aquosum
- B. Edema aquosum
- C. Paltauf hemorrhage
- D. Champignon de mousse (Correct Answer)
Infanticide Methods Explanation: ***Champignon de mousse (Correct Answer)***
- This term, meaning "**mushroom of foam**," describes the **frothy, pinkish fluid** often seen in the airways and on the surface of the lungs in cases of **pulmonary edema**, particularly those caused by **drowning** or acute heart failure.
- The specimen exhibits the characteristic appearance of a **pale lung surface** with scattered **hemorrhagic spots** and sections showing **pinkish froth**, consistent with this classic forensic pathology finding.
- This is a **pathognomonic postmortem finding** in drowning victims and represents acute pulmonary edema with air-mixed fluid in the airways.
*Emphysema aquosum (Incorrect)*
- This term is **not a recognized medical diagnosis** or description for a lung condition.
- While it attempts to combine "emphysema" and "aquosum" (watery), it does not accurately describe a known pathological state or the specimen shown.
*Edema aquosum (Incorrect)*
- This term refers to **generalized edema** or **water retention** throughout the body (anasarca), not specifically a lung finding.
- While pulmonary edema is a type of edema, "edema aquosum" does not precisely describe the **specific postmortem appearance** with characteristic foam formation depicted in the specimen.
*Paltauf hemorrhage (Incorrect)*
- **Paltauf hemorrhages** are characteristic findings in **drowning victims**, presenting as **subpleural ecchymotic hemorrhages** (small hemorrhagic spots beneath the pleural surface).
- While hemorrhages may be present in drowning cases, the **most prominent and pathognomonic feature** shown here is the **frothy appearance** (champignon de mousse) associated with acute pulmonary edema, which is the primary diagnostic finding being illustrated.
