Day 2- Lecture 2- Learning From The Dead Flashcards
History- why did some medical schools conduct autopsies in the winter?
As dissection was challenging experience due to the lack of refrigeration- so in the winter it would reduce the rate of decomposition
When do most dissections take place now?
Part of the postmortem or autopsy
What are the 3 different autopsies carried out in the 21st century?
Medicolegal
- Performed on behalf of the HM coroner
- No consent is needed
Forensic
- Sub-type of coroner’s post-mortems
- Suspicious deaths
Consent (hospital)
- Consent from next of kin
- May limit examination
What is involved in a autopsy?
History
-Often limited in coroner’s cases
External examination
- Natural disease
- Injury
- Medical Intervention
- With or without imaging
Internal examination
- All systems examined in most cases
- BUT limited sometimes especially in consent cases
What are the additional tests taken?
Histology (tissue is fixed, stained and looked at under a microscope)
- For making a diagnosis
- For confirming a diagnosis
Toxicology
- Blood, urine, vitreous, bile etc
- Therapeutic drugs (see if overdosed in hospital)
- Recreational drugs
Biochemistry
- Diabetic ketoacidosis
- Alcoholic ketoacidosis
- Renal failure (test urea and creatine)
Microbiology
-Bacteria, viruses and fungi
Genetics
-DNA fingerprinting
Name and outline the different types of autopsy?
NEUROPATHOLOGY: -Specialised branch of cellular pathology Restricted too... -CNS -Peripheral nerves -Muscle Relevant autopsies -Trauma -Neurodegenerative disease -Research
PAEDIATRIC PATHOLOGY: -Paediatric pathologists are trained in paediatric surgical pathology and autopsy Occur when... -Deaths in utero -Perinatal deaths -Death in infancy (e.g. Sudden infant death) -Suspicious deaths (in conjunction with forensic pathologists) Other info... -Challenging emotionally and technically -Vital in providing answers for grieving families and medical staff -Parents want to know about 'next time' -Medicolegal issues -Safeguarding issues -Teaching and research Examples.... -Macroscopic examination -Microscopic examination -Toxicology -Microbiology -Genetic studies
Forensic pathology
- Small speciality
- More than just autopsies
What do the autopsies provide? (In general)
- Explanations for families
- Forms part of the legal process
- Confirms or refutes criminality
- Raises or alleviates concerns in health and social are settings
What information has examination of dead bodies over centuriesprovided?
- Detailed information of anatomy
- Opportunity to relate structure to function
- Study of effects of disease processes
- Evidence for criminal proceeding
- Ability to assess the impact of therapeutic interventions
Is research involving autopsies still continuing?
Yes, particularly with neurodegenerative disorders. There is often discrepancy between ante-mortem and post-mortem (so diagnosed with something however, after post mortem realise it was actually a different diagnosis)
Give some examples of when a medicolegal autopsy may be carried out?
- Legal requirement
- Deceased unknown
- Deceased not seen by a doctor within 14 days of death
- Attending doctor not able to give cause of death
- Obviously unnatural death (murder, accident, suicide)
- Death related to occupational disease or accident
- Death related to medical treatment or procedure
- People who are in care of the state prisoners, detained in hospital under mental health act)
What are the 4 body parts which can lead sudden death?
- Head
- Heart
- Blood vessels
- Lungs
What is the benefits of post-mortem imaging
- Reduces the need for invasive autopsy
- Already used in forensic cases
