I now have all the necessary information from the forensic medicine textbooks. Let me compile the comprehensive answers.

Question 1: Sexual Offences - Classification, Rape, and Duties of Doctor


Classification of Sexual Offences

Sexual offences are classified as follows (The Essentials of Forensic Medicine and Toxicology, 36th ed.):
#Category
IRape
IIForced/non-consensual insertion
IIISexual acts with animals (Bestiality)
IVParaphilias and paraphilic disorders
VSex-linked disorders

Latest Legal Definition of Rape (Section 63, BNS / S. 375, IPC)

Under the Bharatiya Nyaya Sanhita (BNS) 2023, a man is said to commit "rape" if he:
  • (a) Penetrates his penis, to any extent, into the vagina, mouth, urethra, or anus of a woman, or makes her do so with him or any other person; or
  • (b) Inserts, to any extent, any object or part of the body (not being the penis) into the vagina, urethra, or anus of a woman, or makes her do so; or
  • (c) Manipulates any part of the body of a woman so as to cause penetration into the vagina, urethra, anus, or any part of the body; or
  • (d) Applies his mouth to the vagina, anus, or urethra of a woman, or makes her do so.
Under any of these seven circumstances:
  1. Against her will
  2. Without her consent
  3. With consent obtained by putting her or any person in whom she is interested in fear of death or hurt
  4. With consent when the man knows he is not her husband and her consent is based on mistaken belief
  5. With consent when she is incapable of understanding the nature and consequences due to unsoundness of mind, intoxication, or administration of stupefying substance
  6. With or without consent, when she is under 18 years of age
  7. When she is unable to communicate consent
Explanation:
  • "Vagina" includes the labia majora
  • Consent = unequivocal voluntary agreement communicated by words, gestures, or any verbal/non-verbal communication
  • Failure to physically resist does NOT constitute consent
Exceptions:
  1. A medical procedure or intervention shall not constitute rape
  2. Sexual intercourse by a man with his own wife (wife not being under 15 years) is not rape

Duties of a Doctor in Case of Rape

Immediate Clinical Duties

  1. Obtain written informed consent from the victim (or guardian if minor) before examination
  2. Record detailed history - date, time, and circumstances of the alleged assault; menstrual history; prior sexual activity; use of contraceptives
  3. General physical examination - note general condition, signs of struggle, injuries, emotional state
  4. Document injuries - bruises, abrasions, lacerations on body; bite marks; signs of restraint on wrists/ankles
  5. Genital examination - examine in good light; note condition of hymen (tears, old or fresh); injuries to labia, vagina, perineum, anus; signs of anal penetration if relevant
  6. Collect forensic samples (within 72-96 hours):
    • Vaginal/cervical swabs for semen, sperm, DNA
    • Blood sample (for DNA, drug/alcohol level)
    • Urine sample
    • Nail clippings (for skin/blood of assailant)
    • Clothing (preserve as evidence)
    • Pubic hair combings
  7. Preserve chain of evidence - label all samples properly, seal, and hand over to police with proper documentation
  8. Prepare medicolegal report (MLR) - accurate, objective, and factual; opinion on evidence of sexual intercourse, signs of force or consent, age of victim

Legal Duties

  1. Mandatory reporting - rape is a cognizable offence; doctor must inform police (Section 200, BNS / S. 166B, IPC - failure to provide medicolegal examination is punishable)
  2. Issue Fitness Certificate if required for police custody
  3. Maintain confidentiality while fulfilling legal obligations
  4. Court testimony - be prepared to appear as an expert witness

Therapeutic Duties

  1. Emergency contraception - administer within 72 hours (Levonorgestrel 1.5 mg)
  2. STI prophylaxis - antibiotics for gonorrhea, chlamydia; hepatitis B vaccination; HIV post-exposure prophylaxis (PEP) within 72 hours
  3. Psychological support - refer to counselor/psychiatrist; treat for acute stress reaction
  4. Follow-up - arrange for HIV testing at 6 weeks, 3 months; pregnancy testing


Question 2: Clinical Scenario - Datura (Dhatura) Poisoning

The clinical picture (irritability, restlessness, dry hot skin, inability to pass urine and stools, in a child who ate garden fruits) is classic for Datura poisoning (Dhatura fastuosa / Thorn Apple) - an anticholinergic/deliriant poison.

(a) Definition and Classification of Poison

Definition of Poison: A poison is any substance which, when introduced into or absorbed by a living organism, destroys life or injures health by chemical action.

Classification of Poisons

ClassExamples
1. CorrosivesStrong acids (H2SO4, HCl, HNO3), Strong alkalis (NaOH)
2. IrritantsInorganic (arsenic, phosphorus, copper sulphate); Organic (castor oil, croton oil); Mechanical (glass, diamond dust)
3. Systemic Poisons
- Cerebral (Deliriants)Dhatura, Cannabis, Belladonna, Alcohol
- Cerebral (Soporifics/Narcotics)Opium, chloral hydrate, barbiturates
- Cerebral (Spinal/Convulsants)Nux vomica (strychnine), gelsemium
- Cerebral (Depressants)Hemlock, conium
- CardiacAconite, oleander, digitalis
- AsphyxiantsCO, HCN (hydrocyanic acid)
4. MiscellaneousSnake venom, insect stings, food poisoning

(b) Identification of Poison: DATURA (Dhatura fastuosa)

The poison is Datura/Dhatura - identified by the classic anticholinergic syndrome (remembered as mnemonic):
"Hot as a Hare, Blind as a Bat, Dry as a Bone, Mad as a Hen, Red as a Beet"
Or the 10 D's of Datura Poisoning: Dysphagia, Delusions, Dermatitis, Delirium, Drowsiness, Dry skin/mucous membranes, Dilated pupils, Dreadful hallucinations, Dysuria, Dysarthria

Key Details

ParameterDetails
PlantDatura fastuosa (Thorn Apple / Dhatura); two varieties: Datura Alba (white flowers) and Datura Niger (black/purple flowers)
Poisonous partsAll parts; fruit and seeds most poisonous
Active Principles(i) Hyoscine, (ii) Hyoscyamine, (iii) Traces of Atropine (racemic form of Hyoscyamine)
Mechanism of ActionCompetitive antagonism of muscarinic acetylcholine receptors → blocks parasympathetic effects → produces anticholinergic syndrome (mydriasis, dry skin, hyperthermia, urinary retention, tachycardia, delirium, hallucinations)
Fatal Dose4 fruits; OR 100 seeds; OR 0.5-1 g of seeds
Fatal Period24 hours
AntidotePhysostigmine 0.5 mg IV/IM every 1-2 hours (crosses blood-brain barrier - reverses both central and peripheral effects); Prostigmine (Neostigmine) 0.5-1 mg SC (peripheral effects only); Pilocarpine 5 mg SC as single dose

Signs and Symptoms (matching the scenario)

FeatureDatura Effect
Irritability, restlessnessCentral anticholinergic effects - delirium, hallucinations
Dry, hot skinAnhidrosis + hyperthermia (temp up to 107-108°F)
Unable to pass urineUrinary retention (Dysuria)
Unable to pass stoolsIleus/constipation
Other featuresDilated pupils, flushed face, tachycardia, dryness of mouth, dysphagia

Treatment of Datura Poisoning

  1. Emesis (if patient is conscious)
  2. Gastric lavage - with 5% tannic acid or dilute potassium permanganate solution
  3. Enema with sodium sulphate (purgative)
  4. Physostigmine 0.5 mg IV/IM every 1-2 hours (specific antidote - crosses BBB)
  5. Prostigmine 0.5-1 mg SC (peripheral only)
  6. Pilocarpine 5 mg SC, repeated after 2 hours
  7. Short-acting barbiturates for convulsions
  8. Tepid sponging for high temperature
  9. Artificial respiration + oxygen if needed
  10. Morphine is CONTRAINDICATED (physiological antidote but not used clinically)

Duties of Doctor in Case of Poisoning

  1. Establish diagnosis - take history, identify poison if possible; note time, route, amount ingested
  2. Resuscitate and stabilize - maintain airway, breathing, circulation (ABC)
  3. Inform police - all cases of suspected homicidal or suicidal poisoning must be reported immediately (medicolegal duty); accidental poisoning in children must be reported
  4. Collect and preserve evidence:
    • Vomitus, gastric washings, urine, blood, stool samples
    • Any remaining substance, container, food
    • Label and send to Forensic Science Laboratory with proper chain of custody
  5. Document meticulously - time of admission, symptoms at presentation, treatment given, clinical progress; all entries signed and dated
  6. Do NOT administer antidote before collecting samples (wherever possible)
  7. Issue medicolegal certificate - certify nature of injury/poisoning for legal proceedings
  8. Dying declaration - if patient is likely to die, record the dying declaration in the patient's own words in the presence of a magistrate (if time permits) or on their own with a witness; dying declaration is admissible as evidence in court
  9. Post-mortem cooperation - if patient dies, issue death certificate stating cause; cooperate with medico-legal post-mortem; preserve viscera for chemical analysis
  10. Expert witness - be prepared to testify as expert witness in court
