Knowledge: Bruising in a non-mobile infant is uncommon, and bruising on the ears and cheeks, or any bruise in an infant under about 5 months, is flagged by the validated TEN-4-FACESp screening rule. Classic metaphyseal lesions and posterior rib fractures are highly specific for inflicted injury, and a short fall does not explain multiple fractures of different ages. Mimics include osteogenesis imperfecta, rickets and vitamin D deficiency, copper deficiency, congenital syphilis and bleeding disorders. A repeat skeletal survey at about two weeks improves detection and dating, and ophthalmology review and further neuroimaging should be completed. Fracture and bruise dating is imprecise and should be given as broad ranges, and bruises must not be dated by colour.

Management: I would take the history from each carer separately, recording their words verbatim, and examine the child fully with a chaperone, documenting each bruise on a body chart with scaled photographs. I would advise admission for the child's safety while assessment is completed. I would request bone metabolism and coagulation tests, the repeat survey, ophthalmology review and assessment of any siblings. I would make sure the concern is reported to the child protection authorities and police according to Federal Law No. 3 of 2016 and facility procedure, without waiting for every result. I would write an objective report covering findings, explanations given, mimics excluded and my opinion, with cautious language about timing.

Ethics and communication: The child's welfare comes first, and Federal Law No. 3 of 2016 on Child Rights requires health professionals to report suspected abuse, which overrides parental objection. I would tell the parents honestly that injuries like these must be investigated, without accusing anyone. The guardian consents to tests, but emergency care and reporting proceed if consent is refused. My opinion must stay impartial, recognising both abuse and the harm of a wrong accusation.

Knowledge: Clinical needs come first: emergency contraception, HIV post-exposure prophylaxis, which must start within 72 hours, hepatitis B vaccination, sexually transmitted infection care, injury care and psychological support. At 30 hours, DNA may still be recovered from the vagina and cervix, and from the clothes she wore. Amnesia after a drink raises concern for drug-facilitated assault, so blood and urine should be taken as early as possible, because many drugs clear within hours. Absence of genital injury does not mean assault did not occur. WHO medico-legal guidance covers consent for each step, chaperoning, body charts, photography and chain of custody.

Management: I would see her privately with a female chaperone, explain options and obtain separate consent for clinical care, forensic examination, photographs and release of findings. I would give emergency contraception after a pregnancy test and start HIV prophylaxis and hepatitis B vaccination without waiting for the forensic examination. I would perform a head-to-toe and genital examination, taking swabs in the recommended order, blood and urine for toxicology, and clothing in paper bags. Each sample would be sealed, signed and logged in a chain-of-custody record. I would explain honestly what UAE law and facility policy require about police involvement, so she can decide with full information. I would arrange follow-up for infection testing, prophylaxis adherence and psychological support.

Ethics and communication: She may consent to or refuse each part of the examination, and her capacity should be confirmed given possible drugs. I would not inform her family without her consent. Care must never depend on a police report, but I must not promise confidentiality the law may not allow. A trauma-informed manner, letting her control the pace, reduces further harm.

Knowledge: Exertional heat stroke is likely, but autopsy findings are non-specific, so the diagnosis rests on circumstances, the recorded ante-mortem core temperature and exclusion of other causes. Survival for hours may produce disseminated intravascular coagulation, rhabdomyolysis, acute kidney injury and hepatic necrosis. The differential includes cardiomyopathy, coronary disease, channelopathies, sickle cell trait, stimulant toxicity and sepsis. Admission blood results are valuable because they show creatine kinase, potassium and coagulation before death. Post-mortem body temperature cannot establish heat stroke.

Management: I would obtain paramedic and hospital records, including temperatures, cooling and admission bloods, and ask that ante-mortem samples be retained. I would complete a full autopsy with careful cardiac examination and histology. I would take femoral blood, urine and vitreous humour for toxicology, including stimulants and drugs that impair heat loss. I would test for sickle haemoglobin and keep blood for possible cardiac genetic testing. I would record the work conditions provided by investigators without drawing conclusions about blame. Once results are back, I would give heat stroke as the cause if supported, stating the evidence and the conditions excluded.

Ethics and communication: My role is to determine the cause of death impartially; whether the employer was negligent is for the authorities. Pressure from the employer or co-workers must not influence my findings. The family deserves a clear explanation through the proper channel, with their wish for early burial respected as far as possible. Heat deaths are preventable, and I would support reporting of the occupational risk through the appropriate route.

Knowledge: In typical hanging the mark lies high on the neck, rises obliquely towards the suspension point and is interrupted at the knot, whereas a horizontal, continuous, lower mark is more typical of ligature strangulation. Partial suspension from a door handle is common in suicide, but a homicide can be staged this way. Petechiae are commoner in strangulation, though they can occur in incomplete hanging. Forearm bruises may be defence injuries, or may come from resuscitation or cutting down, so their pattern and age matter. Laryngeal fractures are less common in the young, so their absence does not exclude violence.

Management: I would review scene photographs, examine the suspension point and preserve the ligature with the knot intact. I would photograph and measure the mark, its direction, level and any gaps, and look for fingernail marks and injuries to the lips and mouth. I would take fingernail scrapings and neck swabs for DNA before the body is washed. I would perform a layered neck dissection in a bloodless field after removing the brain and chest organs. I would look for hidden bruising by incising the back and limbs, and examine for sexual assault if indicated. I would send toxicology for sedative drugs. I would give my opinion only after histology and toxicology, setting out the findings that favour each mechanism.

Ethics and communication: My opinion must rest on evidence, not on the police theory or the husband's account, and I must say when findings are ambiguous. Possible domestic violence requires care not to share details that could compromise the investigation. I would document every step so another expert can review my work, and seek a second opinion if uncertain.

Knowledge: Time of death estimation is imprecise: the Henssge nomogram based on rectal temperature gives a confidence interval of several hours that widens with time and with uncertain conditions such as air conditioning. Rigor, hypostasis and gastric contents are even less reliable. Narrowing the interval to suit an investigation without new data would be unscientific and unethical. Features relevant to self-infliction include wound site, direction and depth, hesitation marks, accessibility, clothing disruption and absence of defence injuries, and these give probabilities, not certainty. The expert's duty is to the court, whoever requested the report.

Management: I would tell the officer politely that I cannot change my estimate without new scientific information, such as reliable scene temperature records or the last confirmed sighting. I would record the request and my reply in the case notes. If new data justify a revision, I would issue a supplementary report explaining what changed. In court I would answer the defence question honestly, describing the wound features I recorded, what they suggest and what I cannot determine, and ask to review my photographs if needed. I would not comment outside my expertise, such as on the alibi. I would explain uncertainty in plain language and ranges.

Ethics and communication: Independence is the foundation of forensic practice, and neither police, prosecution nor defence may shape my findings. Pressure to alter evidence should be documented and escalated to my department head. I must be fair to both sides and correct any mistake I discover, even if it weakens the case of the party who called me. Case material stays confidential outside the legal process.

Knowledge: The differential includes lidocaine toxicity, pulmonary thromboembolism, fat embolism, fluid overload, visceral perforation with haemorrhage or sepsis, and sedative complications. Seizures and arrest many hours after infiltration fit lidocaine toxicity, because plasma levels peak late, around 12 hours, after tumescent infiltration. 55 mg/kg is at the top of published ranges, and risk rises with drug interactions and liver disease. Toxicology should quantify lidocaine and its metabolite monoethylglycinexylidide, though resuscitation drugs and redistribution complicate interpretation. Medical liability in the UAE falls under Federal Decree-Law No. 4 of 2016, and the committee needs a clear factual opinion from me.

Management: I would obtain the full records, including consent, drug doses and times, monitoring and discharge notes, and ask that any ante-mortem blood and remaining tumescent solution be secured. I would perform a full autopsy, examining the abdominal wall and cavity for perforation and haematoma, the leg and pelvic veins for thrombus, and the lungs for thrombotic and fat emboli. I would take femoral blood, urine, vitreous humour and liver for toxicology, including lidocaine, its metabolite and sedatives. I would form a cause of death from the combined findings. Questions on whether the surgical standard was met need an independent specialist in that field, and I would say so. I would write plainly, state limitations and avoid comments on blame.

Ethics and communication: I must be independent of the clinic, family and authorities, and declare any conflict, such as having worked with the surgeon. The family should receive an explanation of the cause through the proper channel, with compassion. My report must separate fact, interpretation and opinion. Confidentiality is maintained within the legal process.
