FORENSIC MEDICINE - EXAM PREP NOTE

Nepal Contextualized | All Three Examiners Covered

---

PRIORITY 1 - GUARANTEED TOPICS (All 3 Examiners)

---

1. CONSENT

• Express consent - verbal or written, stated explicitly
• Implied consent - inferred from conduct (e.g., patient extends arm for injection)
• Informed consent - requires full disclosure of: nature of procedure, purpose, risks, benefits, alternatives, and consequences of refusal
• Proxy/substituted consent - given by guardian for minor/incompetent
• Presumed consent - assumed in emergencies when patient cannot consent

1. Disclosure of diagnosis
2. Nature and purpose of proposed treatment
3. Risks and complications
4. Benefits
5. Alternatives available
6. Consequences of refusal
7. Voluntariness confirmed (no coercion)

• Age < 18 years (minor) - guardian/parent must consent
• Mental illness / unsound mind - magistrate consent required
• Intoxication (alcohol/drugs) - consent not valid
• Consent obtained by fraud, force, or misrepresentation
• Consent under undue influence or duress
• Patient in unconscious state

• Minor with no guardian available
• Mentally ill patient with no competent relative
• Prisoner requiring treatment - requires magistrate/court order
• In Nepal, District Court Magistrate issues consent when no valid surrogate is available

1. Emergency/life-threatening situations (implied consent applies)
2. Communicable/notifiable diseases - compulsory treatment (e.g., TB, rabies) under Nepal Public Health Service Act 2075
3. Court-ordered medical examination
4. Insane patient posing danger to self or others

---

2. MEDICAL NEGLIGENCE, RES IPSA LOQUITUR, INFAMOUS CONDUCT

1. Duty of care existed
2. Breach of that duty
3. Damage/harm resulted from that breach

• Error of judgment (not negligence if reasonable care was taken)
• Accepted/standard practice was followed
• Patient's own negligence contributed (contributory negligence)
• Patient did not follow medical advice
• Informed consent was obtained for the risk that materialized
• Act of God / unforeseen complication

• Applied when negligence is so obvious it needs no expert testimony
• Classic examples: swab/instrument left inside patient post-surgery, wrong limb amputated, diathermy burn under anaesthesia
• Shifts the burden of proof to the defendant (doctor must prove they were NOT negligent)

• Examples: advertising professional services, issuing false certificates, covering up for another negligent doctor, sexual misconduct with patients, practicing while drunk, performing procedures outside competence
• In Nepal, dealt with by the Nepal Medical Council (NMC) - can result in suspension or permanent removal from the medical register

• Misconduct = intentional breach of ethics
• Negligence = unintentional failure of duty

---

3. PRIVILEGED COMMUNICATION

1. Patient gives consent to disclosure
2. Court order / subpoena (legal compulsion)
3. Notification of notifiable diseases - Nepal National Public Health Laboratory / Epidemiology and Disease Control Division (EDCD) notifications required
4. Fitness certificates for insurance, employment, driving license
5. Child abuse - reporting to authorities (Child Act 2075 Nepal)
6. Public safety - patient is a danger to others (e.g., epileptic driver)
7. Medico-legal cases - gunshot wounds, poisoning, unnatural deaths must be reported to police in Nepal (per Muluki Criminal Code 2074)

---

PRIORITY 2 - HIGH YIELD

---

4. McNAUGHTEN RULE + CRIMINAL RESPONSIBILITY

• They did not know the nature and quality of the act, OR
• They did not know that what they were doing was wrong

• Under Muluki Criminal Code 2074, Section 9 - a person of unsound mind who cannot understand the nature of the act or distinguish right from wrong is exempt from criminal liability
• Mental illness must be present at the time of the act, not after
• Court may order psychiatric treatment/custody instead of punishment
• Diminished responsibility (not full insanity): may reduce punishment under Section 39 of Muluki Criminal Code

• Doctor's role is to assess mental state, not determine guilt
• Certificate of unsoundness of mind - issued by a psychiatrist, submitted to court
• In Nepal, BP Koirala Institute of Health Sciences (BPKIHS) and Patan Hospital psychiatry departments are commonly used for court-referred assessments

---

5. SEXUAL OFFENCES + RAPE LAW (NEPAL)

• General rape: 7-15 years imprisonment
• Rape of woman < 18 years (statutory rape): up to 20 years
• Rape by person in position of authority (teacher, employer, police, doctor): enhanced punishment
• Gang rape: up to life imprisonment
• Marital rape: up to 5 years (recognized as criminal offense since 2006, Muluki Ain amendment; codified in 2017 Criminal Code)

• Victim < 18 years (statutory rape regardless of consent)
• Unconscious, intoxicated, or under influence of drugs
• Consent obtained by fear, fraud, or impersonation
• Mental illness / incapacity
• In custody of police or other authority (detained person)

• Incest = sexual act between blood relatives (within prohibited degrees)
• Rape = non-consensual sexual act with anyone
• Both can coexist (incestuous rape)
• Nepal Criminal Code 2074 - incest is a separate offense under Chapter on Sexual Offenses

• Torture = infliction of severe pain by person in authority (systematic/purposeful) - prohibited under Nepal's Torture Prevention Act 2017 (Yatana Niwaran Ain 2074) and Article 22 of Constitution of Nepal 2015
• Physical assault = any intentional unlawful application of force

---

6. SUBPOENA / SUMMON

• When summoned, the doctor must appear and give honest, truthful, and objective testimony
• Can be summoned as: Expert Witness (opinion on medical matters) or Ordinary Witness (facts observed)
• In Nepal, issued by court under the Evidence Act and Civil/Criminal Procedure Codes
• Doctor retains professional privilege but must answer direct court questions

---

PRIORITY 3 - BY SYSTEM

---

7. IDENTIFICATION

• Primary identifiers: DNA, fingerprints, dental records (most reliable)
• Secondary identifiers: scars, tattoos, moles, birthmarks, height, weight, eye color, deformities

• Site: specific anatomical location (e.g., right cheek, 2 cm lateral to right nasal ala)
• Size: dimensions in cm
• Shape: circular/oval/irregular
• Color: black/brown/tan
• Surface: smooth/rough/raised/flat
• Any hair present

---

8. INJURIES - ABRASION + CLASSIFICATION

• Simple hurt - minor injury
• Grievous hurt (Section 165 Muluki Criminal Code 2074): Specific injuries - permanent loss of vision, hearing, limb, nose, emasculation, disfigurement of face, fractures, any injury causing death or danger to life, injury preventing victim from ordinary work for >30 days

• Definition: Superficial injury involving only the epidermis/superficial dermis, caused by friction/rubbing force
• Always indicates the point of application of force
• Caused by blunt trauma

1. Scratched/Linear - caused by sharp-edged object drawn across skin (fingernail)
2. Grazed - caused by fall/sliding on rough surface; floor on skin; skin ridges pile up at trailing end (indicates direction of force)
3. Pressure/Patterned - caused by impact with a blunt object leaving its impression (tyre tread, grid pattern)
4. Impact - caused by blunt perpendicular force

• Fresh: red, moist, slightly oozing serum
• 12-24 hrs: drying begins, brown-red scab forming
• 2-3 days: scab fully formed, brownish, edges drying
• 5-7 days: scab starts to lift at edges
• 7-14 days: scab falls off, pink scar beneath

• 14 days: scar fades, may be permanent if deep

---

9. SKULL FRACTURES

1. Linear (fissure) fracture - straight line crack; most common; due to low-energy blunt force over wide area
2. Depressed fracture - fragment pushed inward; indicates site of impact; radiates from impact point
3. Comminuted fracture - multiple fragments
4. Pond's fracture - circular depressed fracture resembling a pond; seen in young children due to ping-pong ball mechanism (green-stick); skull dents inward without true fracture line
5. Hinge fracture - transverse fracture of skull base; hinge passes across sella turcica/dorsum sellae; divides skull into anterior and posterior halves; classically due to RTA/severe lateral force; associated with carotid artery and cranial nerve injuries
6. Gutter fracture - caused by tangential impact (e.g., bullet grazing skull); creates a trough/channel in outer table without penetrating the inner table; indicates trajectory direction

---

10. ASPHYXIA

1. Cyanosis - blue discoloration of lips, fingertips
2. Petechial hemorrhages (Tardieu spots) - over face, conjunctiva, sclera, visceral pleura
3. Congestion - visceral organs congested, dark fluid blood
4. Pulmonary edema
5. Right ventricular dilation

• Drowning death mechanism: Laryngospasm (dry) OR aspiration of water (wet drowning) → hypoxia → unconsciousness → cardiac arrest
• Cadaveric Spasm: Immediate muscle stiffening at the moment of death (no relaxation phase); seen in violent/sudden deaths including drowning; body retains position of last voluntary muscular activity; legally important because it cannot be simulated post-mortem (proves victim was alive at the time and grasped whatever is in hand)
• MLI of cadaveric spasm in drowning: If drowning victim found with weeds/mud clenched in fist - proves they were alive when they entered water (rules out disposal of dead body in water)

---

11. FIREARM INJURIES

• Contact shot: Muzzle held against skin - stellate/cruciate wound, sooting inside, gas blast pattern, burning
• Close range (< 15 cm): Soot + tattooing (unburned powder grains) + singeing of hair
• Intermediate range (15-60 cm): Tattooing only, no soot
• Long range (> 60 cm): Abrasion collar only, no soot/tattooing

---

12. AGE ESTIMATION

• Mixed dentition: 6-12 years
• Successional (permanent) teeth complete: by ~12-14 years
• Wisdom teeth: 17-25 years
• Teeth >25 years: use Gustafson's method (6 features - attrition, periodontosis, secondary dentine, cementum apposition, root resorption, root translucency; each scored 0-3; total score correlates with age)

• Ulna: lower end ossifies 5-6 years, fuses 20 years; upper end (olecranon) 9-10 years, fuses 16-17 years
• Radius: lower end ossifies 1 year, fuses 20-21 years; upper end ossifies 5-6 years, fuses 17-18 years
• Elbow X-ray (CRITOE): Capitellum (1y), Radial head (3y), Internal epicondyle (5y), Trochlea (7y), Olecranon (9y), External epicondyle (11y) - approximate ages

---

13. TOXICOLOGY

Organophosphate (OP) Poisoning

• Mechanism: Irreversible inhibition of acetylcholinesterase (AChE) → ACh accumulates at synapses → cholinergic crisis
• Carbamate vs OP: Both inhibit AChE; carbamate inhibition is REVERSIBLE (spontaneous hydrolysis); OP inhibition is irreversible (aging occurs)
• Clinical: Muscarinic (SLUDGE - Salivation, Lacrimation, Urination, Defecation, GI cramps, Emesis) + Nicotinic (muscle fasciculations, weakness, paralysis) + CNS (seizures, coma)
• Pralidoxime (2-PAM) role: Reactivates AChE by cleaving the OP-AChE bond - MUST be given BEFORE aging occurs (within 24-48 hrs for most OPs). Not useful for carbamates.
• Treatment: Atropine (blocks muscarinic effects, given until atropinization: dry mouth, dry skin, dilated pupils, tachycardia) + Pralidoxime + Diazepam (seizures) + supportive

Zinc Phosphide (ZnP) Poisoning

• Common in Nepal as a rodenticide (used widely in agricultural households)
• Mechanism: Reacts with water/HCl in stomach → releases Phosphine gas (PH3), a direct cellular poison that inhibits cytochrome c oxidase → disrupts oxidative phosphorylation
• Features: Garlicky breath, nausea, vomiting, hypotension, pulmonary edema, hepatotoxicity, cardiac arrhythmias
• Treatment: No specific antidote; supportive; oral sodium bicarbonate may reduce phosphine generation; avoid fats (enhance absorption)

Mercury Poisoning

• Sources in Nepal: Ayurvedic preparations (Parad), industrial, old thermometers
• Inorganic mercury: Acrodynia (pink disease) in children - irritability, sweating, rash, limb pain
• Organic (methyl) mercury: Minamata disease - ataxia, visual/hearing loss, paresthesia, encephalopathy
• Treatment: Dimercaprol (BAL) for acute inorganic mercury; DMSA (succimer) for organic/chronic

Cannabis (Ganja/Bhang)

• Nepal context: Widespread in hills; bhang preparation used in festivals; ganja (dried plant) and charas (resin) common
• Active compound: Delta-9-THC (tetrahydrocannabinol)
• Signs/symptoms: Euphoria, bloodshot eyes (conjunctival injection), increased appetite (munchies), dry mouth, tachycardia, mild hallucinations, impaired short-term memory, laughing
• Chronic: Amotivational syndrome, psychosis (heavy use)

Dhatura (Datura stramonium) + Atropinization

• Nepal context: Grows wild in terai and mid-hills; used in criminal poisoning/robbery (mixed in food/drinks)
• Alkaloids: Atropine + Scopolamine (hyoscine) + Hyoscyamine
• Mechanism: Anticholinergic - blocks muscarinic receptors
• Signs (Mad as a hatter, Blind as a bat, Red as a beet, Dry as a bone, Hot as a hare, Full as a flask):
  • Mydriasis (dilated pupils)
  • Dry mouth/skin
  • Tachycardia
  • Flushing
  • Urinary retention
  • Confusion/hallucinations
• Treatment: Physostigmine (antidote - cholinesterase inhibitor), supportive

Snakes in Nepal

1. Cobra (Naja naja) - Most common cause of snakebite death in Nepal; found in terai/hills
2. Krait (Bungarus caeruleus) - Banded krait and common krait; nocturnal
3. Russell's Viper (Daboia russelii) - Common in terai
4. Saw-scaled viper (Echis carinatus) - Terai region

• Neurotoxic (Cobra, Krait): Blocks NMJ → paralysis → respiratory failure; local tissue reaction mild
• Hemotoxic/Cytotoxic (Russell's viper, Saw-scaled viper): Coagulation defects (DIC, VICC), local tissue destruction, renal failure

• Local: Minimal early swelling, later necrosis
• Systemic: Ptosis, diplopia, dysphagia, dysarthria, respiratory muscle paralysis, death from respiratory failure
• Pain: Burning pain at bite site
• No fang marks visible always - depends on bite angle

• Monovalent: Effective against only one species
• Polyvalent (preferred in Nepal): Effective against all 4 common species (Cobra, Krait, Russell's viper, Saw-scaled viper); recommended because in emergency settings, snake species cannot always be identified; Central-India-raised polyvalent ASV is used in Nepal
• Given IV diluted in NS; watch for anaphylaxis

• Blood: CBC, LFT, RFT, serum electrolytes, blood glucose, coagulation profile (PT/APTT/INR), arterial blood gas, RBC cholinesterase (OP poisoning)
• Urine: Routine, toxicology screen
• Gastric lavage contents: sent for chemical analysis
• Blood/urine toxicology: heavy metal screen, alcohol level, drug screen

---

14. DROWNING TESTS + INFANTICIDE TESTS

• Test for live birth in suspected infanticide
• Principle: Lungs that have breathed air float in water; unexpanded (fetal) lungs sink
• Method: Place lungs in water - if float = breathing occurred = live birth
• MLI: Positive test = evidence of live birth; limitation: putrefaction causes gas and lungs may float falsely; prematurely born baby may have breathed for a short time

• Distinguishes ante-mortem drowning from post-mortem immersion
• Principle: Drowning in fresh water causes hemodilution; salt water causes hemoconcentration in the heart chambers
• Method: Compare chloride content of right vs left heart blood
• Interpretation: In fresh water drowning, left heart blood has LOWER chloride than right; in sea water, left has HIGHER chloride than right; equal chloride = post-mortem immersion (not drowning)

• Diatoms are microscopic algae with silica shells (frustules) that are not destroyed by decomposition or digestion
• Method: Acid digestion of organ tissue (bone marrow, liver, kidney, lung) → examine under microscope for diatoms
• MLI: If diatoms found in bone marrow/liver (remote from lungs), they must have entered circulation during vital period = confirms ante-mortem drowning; finding in lung alone may represent post-mortem washing; site significance: bone marrow positivity is most definitive
• Nepal rivers and lakes contain distinct diatom species - can potentially identify location of drowning

• Muluki Criminal Code 2074: Infanticide = killing of a newborn by the mother within 1 year of birth, in context of mental distress from illegitimate birth/concealment
• Lighter punishment than murder - recognizes the social circumstances
• MLI: Hydrostatic test, stillbirth vs live birth differentiation, signs of neglect/violence on body

• Key: A stillborn baby never breathed; a live-born baby breathed and then died.

---

15. DECOMPOSITION

1. Autolysis - self-digestion by enzymes; first in pancreas, liver; begins immediately after death
2. Putrefaction - bacterial decomposition; produces gases (H2S, NH3, CO2, CH4)
   • First visible sign: Green discoloration of right iliac fossa (cecum - most bacteria here); begins 24-48 hrs in tropical climates
   • Marbling: Green-black discoloration along blood vessels due to Hb + H2S → sulfhemoglobin; visible through skin as a marbled pattern; time since death indicator seen at OSCE
3. Mummification - dry, hot environment → desiccation of tissues; preserves external features
4. Adipocere - saponification; fat converts to soap-like substance (fatty acids + metal ions); wet, anaerobic conditions; preserves body shape; common in Nepal river banks/flooded areas
5. Skeletonization - final stage

---

16. RTA / PEDESTRIAN INJURIES

1. Primary contact injury - bumper injury at tibia level (adult pedestrian); pattern depends on height of bumper
2. Secondary injury - body projected up and forward, hits bonnet/windscreen (head/chest injury)
3. Tertiary injury - body thrown onto road surface (abrasions, lacerations from road surface)
4. Run-over injury - tyre tread pattern injuries; crushing injuries; mutilation

---

17. STARVATION - INTERNAL FINDINGS

• Body: Emaciation, loss of all fat depots (subcutaneous, omental, mesenteric, epicardial)
• Stomach: Empty or contains mucus
• Gallbladder: DISTENDED with thick bile - because gallbladder contracts only in response to food/CCK stimulation; no food = no CCK = gallbladder doesn't empty = accumulation of bile = distension
• Liver: Small, fatty (lipid mobilization from depots) or atrophic
• Intestines: Empty, walls thin and transparent
• Spleen: Small, wrinkled ("washleather spleen")
• Muscle: Atrophied, pale
• Heart: Small; may show brown atrophy (lipofuscin pigment = wear-and-tear pigment)
• Thymus: Atrophy (stress involution)
• Adrenals: Initially hyperplastic (stress response), then atrophy

---

18. EXHUMATION + BODY DISPOSAL IN NEPAL

• Suspected homicide disguised as natural death
• Disputed identification
• Re-examination when new evidence surfaces
• Suspected exhumation by relatives/others

• Ordered by District Court or directed by police under Muluki Criminal Code 2074
• In presence of: Magistrate/police officer, examining doctor (forensic expert), family representative if available
• Body photographed in situ before removal
• All soil samples collected
• Full autopsy performed

• Cremation (Hindus - majority): Body burned on funeral pyre, usually within 24 hours; ash scattered in rivers (Bagmati, Ganges); makes post-mortem investigation impossible once cremated
• Burial (Muslims, Christians, some indigenous groups): Allows exhumation
• Sky burial (Jhator) - practiced by Tibetan Buddhist communities in upper Nepal (Mustang, Dolpo); body exposed to vultures; no body remains for examination
• Water burial - practiced by some communities; body immersed in sacred rivers
• Legal note: Cremation effectively prevents future medico-legal examination; this is why early MLI autopsy is critical before body is released

---

19. EMASCULATION (Panjiyar's specific clarification)

• Classified under Grievous Hurt in Nepal (Section 165 of Muluki Criminal Code 2074)
• Leads to enhanced punishment for the perpetrator

---

20. TURNER & KLINEFELTER SYNDROME (sex determination context)

• Sex: Female (phenotype)
• Chromosomes: 45, X
• Features: Short stature, webbed neck, low posterior hairline, shield chest, widely spaced nipples, coarctation of aorta, streak gonads, primary amenorrhea
• MLI: Female identification by all other criteria; karyotype needed; barr body absent (normally 1 barr body in XX females; 0 in 45X)

• Sex: Male (phenotype)
• Chromosomes: 47, XXY (or XXXY, XXXXY variants)
• Features: Tall, long limbs, small firm testes, gynecomastia, infertility (azoospermia), mild intellectual disability
• MLI: Male identification by external features; karyotype shows extra X; barr body present (1 barr body = 1 inactive X chromosome)

8. Emasculation (including Panjiyar's nerve/spinal clarification)

---

23. ABORTION + MTP ACT (NEPAL)

• 12 weeks - on request (no reason required)
• 18 weeks - if pregnancy results from rape or incest
• Any gestational age - if continuation threatens mother's life or if fetal abnormality incompatible with life

• Must be performed by a licensed health professional

• Woman's written consent required
• No spousal/partner consent required (woman's autonomous right)

• Both allow abortion up to 18 weeks in Nepal
• Incest: Sexual act between blood relatives; prohibited under Muluki Criminal Code; punishable separately

---

OSCE STATIONS - RAPID RECALL

---

HIGH-YIELD SUMMARY TABLE

---

Flag for tomorrow: "Le facie sympathetique" - likely refers to Horner's syndrome (ptosis, miosis, anhidrosis) seen in hanging/strangulation due to cervical sympathetic chain compression, or possibly sympathetic facies in certain toxidromes. Clarify with classmate - could also be a regional/language transcription of "sympathetic ophthalmia" or a specific facial sign in strangulation/asphyxia.

FORENSIC MEDICINE VIVA NOTES

Exam-Ready | All Three Examiners | Nepal Context Throughout

---

TIER 0 — VIRTUALLY GUARANTEED (Memorize First)

---

1. CONSENT

Consent is a voluntary, deliberate, and informed agreement of a mentally competent, legally authorized person to undergo a medical examination, procedure, or treatment, free from force, fraud, or undue influence.

1. Express - clearly stated, verbally or in writing
2. Implied - inferred from actions (e.g., rolling up sleeve for injection)
3. Informed - fully disclosed consent (most relevant medico-legally)
4. Proxy/Substitute - given by parent/guardian on behalf of minor or incompetent person
5. Presumed - assumed in emergency where patient is unconscious

1. Disclosure of diagnosis
2. Nature and purpose of proposed treatment
3. Risks and side effects
4. Benefits of treatment
5. Available alternatives
6. Consequences of refusal
7. Voluntariness — confirmed that no coercion exists

• Age < 18 years (minor) — Nepal law
• Person of unsound mind / mental illness
• Intoxication (alcohol or drugs)
• Obtained by fraud, fear, or misrepresentation
• Under duress or undue influence
• Unconscious patient (unable to express)
• Person detained in custody — magistrate/court consent needed

• Minor with no guardian available
• Mentally ill patient with no competent next of kin
• Prisoner requiring medical treatment
• In Nepal: District Court Magistrate issues court-ordered consent in such cases

A doctor may withhold specific information from a patient if full disclosure would cause serious psychological harm or significantly worsen the patient's condition. It is a limited, carefully justified exception — NOT a license to deceive. Must be documented.

---

2. IDENTIFICATION + AGE ESTIMATION

Identification is the process of establishing the identity of a living or dead person by comparing ante-mortem (known) data with post-mortem findings using biological, physical, and documentary evidence.

Known data = ante-mortem records available for comparison: dental records, fingerprints, DNA, X-rays, photographs, blood group, medical history, implants, tattoos, scars.

• Positive identification - conclusive match (fingerprints, DNA, dental records)
• Presumptive identification - strong but not absolute (physical description, clothing)

1. DNA profiling - absolute; can identify from blood, hair, bone, teeth
2. Fingerprints - unique to every individual; do not change with age

"I have a mole on my [right/left cheek / right forearm / etc.], approximately [X] cm in diameter, oval in shape, dark brown in color, with a smooth, flat surface, located [X] cm [direction] from [bony/facial landmark]." Practice your actual mole. Site + size + shape + color + surface + landmark.

• Loop: 65% (most common)
• Whorl: 30%
• Arch: 5% (least common)

• Suture closure (general sequence): Sagittal → Coronal → Lambdoid
• Spheno-occipital synchondrosis: fuses by 25 years (important for skull-base age)
• Obliteration of sutures: complete by 40-50 years (internal before external)

• Give examples relevant to a 20-25 year old:
  • Medial clavicle epiphysis: ossifies ~18-20 yrs, fuses 25-30 yrs (last to fuse in body)
  • Iliac crest: fuses 20-25 years
  • Spheno-occipital: fuses 25 yrs
• Ribs/sternum, vertebral ring epiphyses: fuse ~25 yrs

• Iliac crest: appears 13-15 yrs, fuses 20-25 yrs
• Head of femur: ossifies 1st year, fuses 18 yrs
• Greater trochanter: ossifies 2-4 yrs, fuses 18 yrs
• Lesser trochanter: ossifies 13-14 yrs, fuses 17-18 yrs
• Tri-radiate cartilage of acetabulum: fuses 16-18 yrs

Six features scored 0-3 each: Attrition, Periodontosis, Secondary dentine, Cementum apposition, Root resorption, Root translucency. Total score plotted against regression formula to calculate age. Max score 18.

---

3. SEXUAL OFFENCE + RAPE LAW

Any unwanted sexual contact or behavior that occurs without explicit consent. Includes rape, attempted rape, non-penetrative sexual touching, forced oral acts.

Under Muluki Criminal Code 2074 (MCC), Section 219: Rape is penile penetration of the vagina, mouth, or anus of another person without their consent, or against their will, or with a person below 18 years.

• General rape: 7-15 years imprisonment
• Victim < 18 years (statutory rape): up to 20 years
• Person in authority (doctor, teacher, police, employer): enhanced punishment
• Gang rape: up to life imprisonment
• Marital rape: up to 5 years (recognized as offense since MCC 2074)
• Incestuous rape: treated as both rape AND incest; cumulative punishment may apply

Having sexual intercourse with a woman by impersonating her husband or any person she knows — constitutes rape even if the woman "consents" because the consent is vitiated by fraud/deception. MCC 2074 recognizes this.

1. Age < 18 years (Nepal)
2. Unconscious or asleep
3. Under influence of alcohol/drugs
4. Mental illness
5. Consent by fraud/impersonation
6. Person in custody/detention
7. Consent under threat or coercion

• Incest: Sexual act between blood relatives within prohibited degrees (parent-child, siblings, uncle-niece) — separate offense under MCC 2074; criminal even if consensual
• Rape: Non-consensual sexual act with anyone — requires non-consent as essential element
• Both can coexist: incestuous rape carries dual liability
• For abortion purposes in Nepal: pregnancy from BOTH rape and incest allows termination up to 18 weeks

---

4. POST-MORTEM CHANGES

Rigor Mortis

Rigor mortis is the stiffening of muscles after death due to depletion of ATP, causing irreversible cross-linkage of actin and myomyosin filaments.

After death → ATP production ceases → calcium ions flood the sarcoplasm → actin-myosin bonds form but cannot detach (no ATP to break them) → muscles locked in contracted state → rigor.

• Appears: 1-2 hours after death (starts in jaw/neck)
• Complete: 12 hours
• Maintained: 12 hours (12-24 hrs total)
• Passes off: 12 hours (24-36 hrs after onset, muscles relax due to autolysis/bacterial proteolysis)
• Sequence: Jaw → Neck → Trunk → Upper limbs → Lower limbs (Nysten's law — follows descending nerve degeneration)
• Passes off in same order

• Faster onset + shorter duration: High temperature, physical exertion before death, febrile illness, strychnine poisoning
• Slower onset + longer duration: Cold environment, cold-water drowning, old age, debilitated patients

Hypostasis (Post-Mortem Lividity / Livor Mortis)

Hypostasis is the purple-red discoloration of skin in dependent parts of the body due to gravitational settling of blood into capillaries and venules after the heart stops.

• Starts: 30 min - 2 hours after death (faint patches)
• Well-established: 6-8 hours (fixed in position)
• Fully fixed: 8-12 hours (pressure will not cause blanching)

1. Confirms death
2. Suggests time of death
3. Indicates position of body at time of death
4. Position of lividity vs body position = can detect if body was moved (lividity won't match current position if moved after fixation)
5. Contact pallor / pressure pallor: Areas compressed against a surface remain pale (blood squeezed out) — can reveal pattern of surface body was lying on

Areas of skin in contact with a firm surface show pallor (whiteness) within the otherwise purple-red lividity — because capillaries are compressed and blood cannot pool there. Can reveal imprint of floor tiles, clothing folds, etc.

• Purple-red (normal): decomposed Hb
• Bright cherry red: CO poisoning (carboxyhemoglobin)
• Brick red: Cyanide poisoning
• Pale pink: Cold exposure, refrigeration
• Brown: Methaemoglobinaemia (nitrite poisoning)

Mummification

Mummification is a form of preservation of the body where dehydration and desiccation of tissues occurs due to hot, dry, well-ventilated environment, preventing putrefaction.

• Hot + dry + well-ventilated environment
• Low humidity

• Can occur in 3-4 months (faster in desert/hot conditions)
• In Nepal: possible in the dry high-altitude regions (Mustang, Manang)

• Preserved external features — identification possible
• Injury patterns may be preserved
• Toxicology possible from hair/nails/bone
• Prevents early decomposition/putrefaction timelines

Brown-black drying artifact on the sclera (white of eye) seen when eyelids remain open after death. Cornea dries and turns brown/black. NOT a pathological lesion — a PM drying artifact. Appears within hours of death.

Petechial (pinpoint) hemorrhages seen on visceral pleura, epicardium, and conjunctiva in deaths from asphyxia. Caused by raised intravascular pressure + capillary rupture due to oxygen deprivation and venous engorgement.

5. TORTURE

Torture is the deliberate, systematic infliction of severe physical or mental pain/suffering by a person acting in an official capacity (state agent or person acting with official complicity) with the purpose of obtaining information, confession, intimidation, or punishment.

• Prohibited under Constitution of Nepal 2015, Article 22 ("Right against torture")
• Torture Prevention Act 2017 (Yatana Niwaran Ain 2074) — provides for compensation and criminal prosecution
• NHRC (National Human Rights Commission) receives torture complaints

Falanga (also called bastinado) is a specific torture method involving repeated beating of the soles of the feet with a rod or baton.

• Injuries: Pain, bruising, swelling of soles, stress fractures of small bones of feet (metatarsals, phalanges), plantar fasciitis, nerve damage
• Important: Soles of feet show remarkable bruising and swelling despite relatively minor external visible signs — this is why it is favored as a "hidden torture" method
• Long-term: Chronic foot pain, difficulty walking

1. Document injuries accurately (pattern + distribution)
2. Assess age of injuries (to match timeline)
3. Assess psychological sequelae (PTSD screening)
4. Collect medico-legal evidence for prosecution
5. Provide immediate medical care
6. Report to human rights bodies (NHRC Nepal) if indicated

International standard for investigating and documenting torture. Guides the medical examination of suspected torture victims. Nepal is a signatory to the Convention Against Torture (CAT, ratified 1991).

6. ASPHYXIA + PM CHANGES

Asphyxia is a condition characterized by inadequate supply of oxygen (hypoxia) to the tissues with concurrent excess of carbon dioxide (hypercapnia), caused by mechanical interference with respiration, leading to unconsciousness and death if uncorrected.

1. Mechanical obstruction of airway/respiration
2. Oxygen falls; CO2 rises
3. Hypoxia → anaerobic metabolism → lactic acidosis
4. Respiratory distress → violent attempts to breathe
5. Cerebral hypoxia → convulsions → unconsciousness
6. Cardiac hypoxia → arrhythmia → cardiac arrest → death

1. Cyanosis — blue discoloration of lips, face, fingernails
2. Petechial hemorrhages (Tardieu spots) — conjunctiva, visceral pleura, epicardium
3. Congestion — dark, engorgement of viscera; dark fluid blood
4. Oedema — pulmonary oedema + cerebral oedema
5. Right heart dilation — RV dilated due to increased pulmonary resistance

• Typical/Complete hanging: Entire body weight suspended; feet off ground
• Partial hanging: Some body support remains (knees on floor, sitting)
• Judicial hanging: Drop 6 feet — C2 fracture-dislocation + atlanto-axial dislocation → spinal cord transection → instantaneous death
• Suicidal partial hanging: Most common; body not fully suspended

In hanging, the side of the face opposite to the knot shows more congestion and petechiae, while the knot side shows pallor (carotid compressed on that side prevents venous return from that hemisphere). This facial asymmetry helps determine knot position at autopsy.

• Mechanical: Airway directly compressed (hanging, strangulation, smothering)
• Postural: Body position compresses chest/diaphragm preventing breathing (e.g., person wedged upside down, drunkard fallen with head down; infant in unsafe sleeping position — link to SIDS)

• Sudden Infant Death Syndrome — unexplained death of infant < 1 year during sleep
• PM findings: petechial hemorrhages on thymus/visceral pleura, mild pulmonary congestion, no definitive cause found — diagnosis of exclusion
• Nepal: must be differentiated from infanticide and overlying (mechanical asphyxia by bedding)

7. PROFESSIONAL MISCONDUCT / NEGLIGENCE / ETHICS

A mnemonic for types of infamous conduct:

1. Adultery / Improper sexual conduct with patient
2. Abuse of professional position (e.g., prescribing narcotics to oneself)
3. Association with unqualified persons (dichotomy/covering for quacks)
4. Advertising professional services
5. Abortion — criminal/illegal abortion
6. Alcoholism/drug dependence affecting professional competence

Conduct by a medical practitioner that would be regarded by professional peers as dishonourable or disgraceful to the profession, whether or not it constitutes a criminal offense.

• Ethics: Moral principles governing a doctor's conduct toward patients and society — duties, rights, obligations
• Etiquette: Professional courtesy between colleagues — e.g., not criticizing a fellow doctor in front of a patient, not stealing another's patient

1. Magistrate's Inquest (Police Inquest) — conducted by magistrate/police officer for deaths that are: unnatural, suspicious, violent, or unknown cause. In Nepal: under Muluki Criminal Procedure Code.
2. Coroner's Inquest — exists in UK/Western countries; judicial investigation; not used in Nepal
3. Medical Examiner system — USA; forensic pathologist-led; not used in Nepal

1. Unnatural death
2. Unknown cause of death
3. Undignified/Undocumented death (unknown person)

• Do no harm (primum non nocere)
• Teach the art to successors
• Maintain confidentiality
• Not perform abortion or surgery (historical — now evolved)
• Not have improper relations with patients
• Regard teacher as parent
• Nepal medical graduates take an adapted oath at graduation

SKULL FRACTURE TYPES

A circular, depressed skull fracture resembling a pond, seen in infants and young children whose skull is still pliable. The bone dents inward like a ping-pong ball without a radiating fracture line. Caused by a focal blunt impact on an incompletely ossified skull.

A transverse fracture of the skull base passing through the sella turcica / dorsum sellae, effectively "hinging" the skull into anterior and posterior halves. Caused by severe lateral force (RTA, fall from height). Associated with: carotid artery injury, cranial nerve III/IV/VI palsy, and basilar skull fracture signs (raccoon eyes, Battle's sign, CSF otorrhea/rhinorrhea).

A tangential fracture caused by a glancing/grazing blow (e.g., bullet grazing the skull surface). Creates a trough or channel in the outer table without fully penetrating. Helps determine trajectory and direction of force.

When two lines of fracture meet, the second fracture stops at the first because the energy is already dissipated by the first fracture line. This determines which blow landed first in cases of multiple head injuries.

GRIEVOUS HURT + VITRIOLAGE

Under Section 165, Muluki Criminal Code 2074, grievous hurt includes:

1. Permanent loss of sight (either eye)
2. Permanent loss of hearing (either ear)
3. Loss of any limb or joint
4. Permanent impairment of limb/joint function
5. Permanent disfiguration of face or head
6. Fracture or dislocation of bone or tooth
7. Injury causing danger to life or inability to carry out ordinary duties for > 30 days
8. Emasculation (including nerve/spinal cause of non-functional reproductive organs)

Vitriolage is the act of throwing a corrosive substance (acid, alkali, or caustic material) at a person with intent to cause grievous hurt, particularly disfigurement.

• Common agents: Sulfuric acid (vitriol), hydrochloric acid, caustic soda, battery acid
• Nepal context: Acid attacks are a recognized crime; treated as grievous hurt with enhanced punishment under MCC 2074; increasing in Nepal particularly against women in domestic/intimate partner disputes
• Injuries: Full-thickness chemical burns, permanent disfigurement, blindness, respiratory damage from fumes

---

CADAVERIC SPASM — DETAILED

Cadaveric spasm (instantaneous rigor/cataleptic rigidity) is the immediate stiffening of a group of muscles at the exact moment of death, without any preceding period of muscular flaccidity (primary relaxation).

At the moment of violent/sudden death under extreme emotional or physical stress — the nerve impulses continue momentarily after death, depleting local ATP instantaneously in the active muscles, causing immediate, irreversible contraction.

• Drowning (grasping at water/weeds)
• Violent struggle (grasping a weapon)
• Sudden cardiac arrest during exertion
• Deaths by lightning
• Deaths under extreme fear/emotion

1. Cannot be reproduced post-mortem — distinguishes from natural rigor placed after death; proves victim was alive in that position
2. Drowning: Weeds, mud, gravel found tightly clasped in hand → victim was alive when they entered water → rules out "dead body dumped in water" defence
3. Shooting/stabbing: Firearm/knife gripped at death → consistent with suicide (can also be interpreted in homicide)
4. Identifies the exact posture and activity at the time of death

• Heat stiffening (body exposed to fire — muscles contract due to heat, not neural mechanism)
• Cold stiffening (cold exposure stiffens soft tissues — not true rigor or spasm)
• Rigor mortis (develops later, involves all muscles, has relaxation phase)

RESHMA MA'AM — DETAILED NOTES

---

McNAUGHTEN RULE + CRIMINAL RESPONSIBILITY

Established in England, 1843 following the trial of Daniel M'Naghten, who killed the British Prime Minister's secretary believing he was being persecuted. House of Lords established the insanity defense criteria:

A person is not criminally responsible if, at the time of the act, due to a disease of the mind, they either:

1. Did not know the nature and quality of the act they were doing, OR
2. Did not know that what they were doing was wrong

Muluki Criminal Code 2074, Section 9: A person of unsound mind who cannot understand the nature of their act or distinguish right from wrong is exempt from criminal liability. The mental disease must have been present at the time of committing the act.

Court may order: psychiatric treatment, detention in a mental health facility, or supervised care — rather than imprisonment. Based on Nepal Mental Health Act 2017 (Manoswasthya Ain 2074).

Forensic psychiatrist assesses: (a) presence of mental disease, (b) whether it affected understanding/knowledge of wrongfulness at the time of act, (c) fitness to stand trial. Issues certificate to court — this is medico-legal evidence, not legal determination.

Some legal systems also recognize that even if a person knew an act was wrong, if they were unable to control the impulse due to mental disease, they may still be not responsible. Nepal MCC does not explicitly codify this but courts may consider it under Section 9.

---

FIREARM — VIVA FOCUSED

1. Confirm entry vs exit wound
2. Determine range of fire
3. Determine direction of fire
4. Determine type of weapon
5. Determine nature of bullet/projectile
6. Distinguish suicide/homicide/accident

75% potassium nitrate (KNO3) + 15% charcoal (C) + 10% sulfur (S) Smokeless powder (modern): nitrocellulose (gun cotton) ± nitroglycerin

• Contact: Stellate/cruciate wound; sooting inside wound; singeing; muzzle imprint; gas blast injury
• Close range (< 15 cm): Blackening (soot) + tattooing + singeing
• Intermediate (15-60 cm): Tattooing only (unburned powder grains embedded in skin); no soot
• Long range (> 60 cm): Abraded collar only; no soot, no tattooing

A cartridge whose bullet is fired through a barrel with helical spiral grooves (rifling). The grooves spin the bullet, giving it gyroscopic stability and accuracy. The cartridge case is ejected after firing. Rifling marks on the recovered bullet can be matched to the specific firearm.

• Contact/close: One large irregular wound, all pellets together
• 1-2 metres: Ragged large hole with small satellite pellets
• 3-4 metres: Central large wound + peripheral pellet holes

• 4 metres: Scattered individual pellet holes; pellets spread widely

---

OP POISONING — VIVA QUESTIONS

Organophosphates irreversibly inhibit acetylcholinesterase (AChE) → ACh accumulates at muscarinic and nicotinic synapses → cholinergic crisis.

• Both inhibit AChE
• Carbamate: reversible, spontaneous hydrolysis of the carbamate-AChE bond → recovery without pralidoxime
• OP: irreversible after "aging" (time-dependent irreversible conformational change of the OP-AChE complex)

Pralidoxime reactivates the AChE by competitively displacing the OP from the AChE active site — must be given before aging occurs (within 24-48 hours for most OPs; some OPs age within minutes). After aging, 2-PAM has no effect. Not used in carbamate poisoning (spontaneous recovery; 2-PAM may paradoxically inhibit AChE in carbamate poisoning).

• Muscarinic (SLUDGE): Salivation, Lacrimation, Urination, Defecation, GI cramps/vomiting, Emesis; also: bradycardia, bronchospasm, miosis (pinpoint pupils)
• Nicotinic: Muscle fasciculations, weakness, paralysis (including diaphragm → respiratory failure)
• CNS: Anxiety, seizures, coma

1. Atropine — competitive antagonist at muscarinic receptors; titrated until "atropinization" (dry skin/mouth, dilated pupils, tachycardia, reduced secretions)
2. Pralidoxime — reactivates AChE (before aging)
3. Diazepam — for seizures
4. Supportive: Airway, ventilation, gastric lavage if early oral ingestion

---

INQUEST — DETAILED

Inquest is an official, formal inquiry into the fact, cause, and circumstances of a sudden, unexpected, suspicious, or violent death.

1. Police Inquest (most relevant in Nepal):
   • Conducted by Sub-Inspector or above under Muluki Criminal Procedure Code 2074
   • For all unnatural, suspicious, violent, or unknown deaths
   • Doctor's role: examine body, provide opinion on cause of death, document injuries
   • Inquest form filled in presence of 2 witnesses
2. Coroner's Inquest (England): Judicial officer (Coroner) leads inquiry; jury may be involved; not applicable in Nepal
3. Medical Examiner system (USA): Forensic pathologist makes all death certification decisions; not applicable in Nepal

An autopsy in which no definitive cause of death is found despite thorough examination. Can occur in: smothering, drowning (rarely), electrocution (may leave no marks), some poisoning cases, SIDS. Importance: establishes that death was not due to any traumatic or structural pathology found at autopsy; histology + toxicology must then be sent.

---

COUP-CONTRECOUP / CONCUSSION

Brain injury at the site of impact — caused by direct transmission of force to the brain beneath the point of impact.

Brain injury opposite to the site of impact — caused by the brain rebounding against the opposite inner surface of the skull. Generally more severe than coup in moving-head impacts (e.g., falls).

Temporary, reversible loss of consciousness/neurological function following a head injury, without structural brain damage. Due to diffuse axonal injury at the time of impact. No gross anatomical lesion at autopsy.

---

CEPHALIC INDEX

Cephalic Index = (Maximum breadth of skull ÷ Maximum length of skull) × 100

• Dolichocephalic (long-headed): CI < 75 — common in Africans, Northern Europeans
• Mesocephalic (medium): CI 75-80
• Brachycephalic (short/round-headed): CI > 80 — common in Mongols, Asians

---

SOMNIFEROUS POISONS

Poisons that produce sleep/stupor/unconsciousness as their primary effect.

• Examples: Opioids (morphine, heroin), benzodiazepines, barbiturates, chloral hydrate, alcohol, antihistamines, GHB (date rape drug)

Triad: Pin-point pupils (miosis) + Unconsciousness + Respiratory depression

• Also: Bradycardia, hypotension, cold clammy skin
• Antidote: Naloxone (Narcan) — competitive opioid receptor antagonist; IV/IM/intranasal; may need repeat dosing

Historically: 2 parts activated charcoal + 1 part magnesium oxide + 1 part tannic acid Modern standard: Activated charcoal alone (50g adult dose) — adsorbs most poisons non-specifically. "Universal antidote" as a compound is largely obsolete.

Empirical treatment given to any unconscious patient of unknown cause:

1. Dextrose 50% (hypoglycemia)
2. Thiamine/Vitamin B1 (Wernicke's prevention; given before glucose)
3. Naloxone (opioid reversal)
4. Flumazenil (benzodiazepine reversal — use cautiously; can precipitate seizures in mixed-drug overdose)

PANJIYAR SIR — DETAILED NOTES

---

VISCERA PRESERVATION — VERY HIGH YIELD FOR PANJIYAR

To prevent decomposition and chemical changes that would render toxicological analysis unreliable. Preservation maintains the poison/metabolite in analyzable form.

Standard preservative for viscera in India/Nepal. 1 part salt : 2 parts water (saturated). Why NOT formalin? Formalin (formaldehyde) destroys organic poisons and interferes with most toxicological assays — never use for forensic toxicology specimens. Why NaCl? Prevents bacterial decomposition without chemically altering the poison.

• Stomach contents + around bite site tissue
• Preserved in glycerol or saturated NaCl
• Serum for ELISA venom detection
• Send to: forensic toxicology lab or BPKIHS/teaching hospital lab in Nepal

• Stomach + contents, intestines, liver, urine
• Preservative: Saturated NaCl
• Testing: Mydriatic test (inject sample into cat's eye → pupil dilates if atropine present), Vitali-Morin test

NaF is added (along with saturated NaCl) to blood/urine specimens to:

• Prevent fermentation of glucose to alcohol by bacteria (crucial when blood alcohol analysis is needed — without NaF, bacterial fermentation would falsely elevate alcohol level)
• Inhibit enzymatic degradation
• Used specifically for: blood alcohol, glucose estimation Always combine: grey-top tube (NaF + potassium oxalate) for blood alcohol and glucose samples.

---

AUTOPSY — DEFINITION + OBJECTIVES

Autopsy (post-mortem examination) is the systematic dissection and examination of a dead body to determine the cause of death, manner of death, and any injuries or diseases present.

1. Medico-legal / Forensic autopsy: Ordered by court/police; no family consent required; purpose is to determine cause of death for legal proceedings; in Nepal under MCC 2074
2. Medical / Clinical autopsy: Requested by clinician with family consent; academic/quality improvement purpose
3. Partial autopsy: Limited examination of specific body part

1. Determine cause of death (immediate, underlying, contributory)
2. Determine manner of death (natural, accident, homicide, suicide, undetermined)
3. Determine time of death
4. Identify the deceased
5. Recover trace evidence (bullets, fibres, hair, semen)
6. Document injuries (number, nature, pattern, age)
7. Provide medico-legal evidence for court
8. Collect specimens for toxicology/histology

---

PROFESSIONAL MISCONDUCT — 6As (Panjiyar + Reshma)

1. Adultery / sexual impropriety with patient
2. Abuse of professional position
3. Association with unqualified practitioners
4. Advertising
5. Abortion (criminal)
6. Addiction (alcoholism/drug dependence affecting practice)

Nepal Medical Council (NMC) — statutory body under Nepal Medical Council Act 2020 (2077 BS). Can:

• Issue warning
• Suspend registration temporarily
• Cancel registration permanently

Criminal acts simultaneously prosecuted under MCC 2074.

---

ABORTION — NEPAL LAW

Intentional termination of pregnancy before the fetus is viable (generally before 28 weeks).

Nepal legalized abortion in 2002 (one of the first countries in South Asia). Current framework under Muluki Criminal Code 2074 + Safe Abortion Policy Nepal:

• Up to 12 weeks: On woman's own request — no reason required
• Up to 18 weeks: Pregnancy resulting from rape or incest
• Any gestational age: Continuation threatens mother's life, or lethal fetal abnormality

Must be performed at a certified safe abortion facility by a licensed provider Woman's own written consent is sufficient — no spousal/partner consent needed

Abortion performed: outside legal conditions, by an unauthorized person, without proper consent, using dangerous methods, or at an unauthorized facility. Punishable under MCC 2074 — imprisonment for both provider and person requesting (if done illegally).

---

HANGING TYPES + KNOT POSITION

• Complete: Feet off ground
• Incomplete/Partial: Some body support (most common suicidal method in Nepal and globally)

• Typical: Knot at back of neck
• Atypical: Knot at front, side of neck
• Facial asymmetry: Knot-side face is paler; opposite side is more congested (carotid/jugular compression pattern)

---

ADULTERY (Nepal law)

Voluntary sexual intercourse between a married person and someone other than their spouse.

Adultery was decriminalized in Nepal under the Muluki Criminal Code 2074 — it is no longer a criminal offense (previously punishable under old Muluki Ain). It may still have civil law implications (grounds for divorce under Muluki Civil Code 2074) but is not prosecuted criminally.

---

CASPER'S DICTUM

"One week of decomposition in air = 2 weeks in water = 8 weeks in soil" Meaning: Decomposition rate is fastest in air, intermediate in water, slowest in soil (due to temperature, oxygen, microbial access). MLI: Helps estimate time since death when body is recovered from water or buried.

---

CORPUS DELICTI

Literally "body of the crime." In law, it refers to the essential factual elements that must be proven to establish that a crime has occurred. In murder cases, it includes proof that: (1) death has occurred, and (2) death was caused by criminal agency. It does NOT mean only the physical body — it means the substance of the crime has been established.

---

LOCARD'S PRINCIPLE

"Every contact leaves a trace." Every time two objects/persons come into contact, they exchange material — hair, fibres, blood, soil, fingerprints, DNA. This is the foundation of forensic trace evidence. Applied in Nepal: fibres/hair found at crime scene, soil on shoes, blood transfer patterns.

---

HASSE'S RULE + MORRISON'S MODIFICATION

• For first 5 months: Length of fetus in cm = (month)² (e.g., 3 months = 9 cm crown-rump)
• For last 5 months: Length of fetus in cm = month × 5 (e.g., 7 months = 35 cm)

Modifies Hasse's rule to use foot length instead of crown-rump length, as foot is easier to measure in early fetuses.

---

CHEILOSCOPY

Cheiloscopy is the study of lip prints (patterns of grooves/furrows on the lip mucosa) for identification purposes. Like fingerprints, lip prints are unique to an individual and do not change with age. Pattern types: straight, curved, angled, branching lines.

---

TIER 3 — QUICK ANSWERS (Brief, Viva-ready)

• Mercury (inorganic): acrodynia, tremor, neuropsychiatric ("mad hatter"); treat with dimercaprol
• Lead (chronic): basophilic stippling, Burton's line (blue-black on gums), wrist/foot drop, anemia; treat with DMSA or CaEDTA

A person who gives evidence in a court of law about facts they have personally observed. Expert witness: gives opinion based on specialized knowledge (forensic doctor). Ordinary witness: testifies only to facts observed.

LAST-MINUTE VIVA SMART TIPS

1. When she asks "describe your own identifying mark" — give a specific, anatomically-located, measured description. Practice yours now.
2. On consent questions — always end with the Nepal legal framework: District Court magistrate for incompetent/minor without guardian; MCC 2074 framework.
3. On rape punishment — recite the tiered structure: 7-15 yrs general → 20 yrs victim < 18 → life for gang rape → 5 yrs marital rape.
4. On rigor mortis mechanism — always say: ATP depletion → calcium floods sarcoplasm → actin-myosin cross-links form and cannot detach. This is the "mechanism" answer they want.
5. On hypostasis — always mention contact pallor and position-change detection — these are MLI-heavy answers that score well.
6. On viscera preservation — always state WHY NOT formalin, then say what you use and why. That's what Panjiyar wants to hear.
7. On 6As — list all 6 confidently. If you forget one, they will prompt — don't panic.
8. On NaF — the key answer is "prevents fermentation of glucose to alcohol" — this is what blood alcohol samples specifically need.
9. On cadaveric spasm — always say "cannot be simulated post-mortem" — this is the #1 MLI they expect you to state.
10. Locard, Casper, Hasse — one-line each; know the numbers.
