Individualised and non-contact post-mortem interval determination of human bodies using visible and thermal 3D imaging

Determining the time since death, i.e., post-mortem interval (PMI), often plays a key role in forensic investigations. The current standard PMI-estimation method empirically correlates rectal temperatures and PMIs, frequently necessitating subjective correction factors. To overcome this, a thermodynamic finite-difference (TFD) algorithm was previously developed, providing a rigorous method to simulate post-mortem temperatures of bodies assuming a straight posture. However, in forensic practice, bodies are often found in non-straight postures, potentially limiting applicability of this algorithm in these cases. An individualised approach has been developed, enabling PMI reconstruction for bodies in arbitrary postures by combining photogrammetry and TFD modelling. Utilising thermal photogrammetry, this approach also represents the first non-contact method for PMI reconstruction. The performed lab and crime scene validations reveal PMI reconstruction accuracies of 0.26 h ± 1.38 h for true PMIs between 2 h and 35 h and total procedural durations of ~15 min.

'Unprecedented' rise in drug overdoses in England linked with synthetic opioid

In a National Patient Safety alert issued on 18 August 2021, Public Health England (PHE) said that there have been an “unprecedented number of overdoses” and testing has showed that three cases involved heroin adulterated with the synthetic opioid isotonitazene. “Isotonitazene’s potency and toxicity are uncertain but perhaps similar to, or more than fentanyl, which is about 100x morphine,” said PHE. At least 46 poisonings and 16 deaths have been reported and have been linked to isotonitazene.

Reconstruction and physical fit analysis of fragmented skeletal remains using 3D printing and imaging

Physical fit analysis (PFA) entails physically fitting fragmented evidence together to determine shared origin. PFA can be challenging to conduct with bone fragments particularly when fragile, sharp, or embedded in other materials. Three-dimensional (3D) imaging and printing techniques can circumvent these challenges. Two different 3D imaging techniques were compared and by generating virtual 3D models and prints of burned human bone fragments, the suitability of these techniques was tested. It was found that 3D imaging and printing allowed for effective PFA without excessively handling the original fragments.

Please see below for a message from The History and Philosophy of Medicine & Pharmacy (Faculty of the History and Philosophy of Medicine and Pharmacy - The Worshipful Society of Apothecaries)

The Faculty has some new exciting courses to offer you and hope you will share our enthusiasm and spread the word.
Our new Online Pharmacy History Explorer Course has just opened and will be available until the end of October 2021. Learn at your own pace and join us on either or both of our live discussion dates with speakers and course organisers: https://www.apothecaries.org/apoth-explorer-course/
The History of Medicine Course (https://www.apothecaries.org/the-history-of-medicine/) and Philosophy of Medicine Course (https://www.apothecaries.org/the-philosophy-of-medicine/) will form a blend of in-person and online days. We already have participants from all of the world joining our courses this year!

The Faculty offers a student rate for the course, the examination fee is separate. The Faculty is able to offer limited exam bursaries that will cover two thirds of the exam fee. The criteria is on each of the course page links above. Entrance to the course will close on 1st November 2021.

Acute renal failure from envenoming syndrome after massive bee attack

Envenoming syndrome is a systemic toxic reaction to the inoculation of large volume of insect venom, typically after a swarm attack from bees. Africanized honey bees are notorious for their aggressive nature, and human deaths resulting from Africanized honey bee attacks are consistently reported. Whereas anaphylaxis is the most common lethal mechanism of injury, delayed deaths can also occur as a consequence of severe venom toxicity with resultant end organ damage. Acute renal failure complicating massive envenomation is a rare but potentially fatal outcome after Africanized honey bee attack and may be heralded by laboratory evidence of rhabdomyolysis.

Knife Angel

On Monday 6th September a Knife Angel was erected in Central Park, Chelmsford. The statue is dedicated to victims of knife crime.
 
Unveiled in 2017, the statue has travelled to locations around the country warning communities of the consequences of knife crime and aggression. It is first time the sculpture has come to Essex. Luisa Di Marco, the founder of Keep It 100 Essex, a charity set up with the aim of improving aspirations for youngsters and tackling youth violence through art and culture, was the driving of bringing the sculpture to the county.
 
The unveiling of the statue kick starts a month of events raising awareness of the effects of knife crime and looking at addressing its causes.
