Forensic International Dental Database (FIDBv2) for adult age-at-death estimation in multiple forensic contexts: Strengthening the operationalization of the Lamendin criteria in a global scope model.

The aim of this study is to validate the FIDBv2 online procedure for adult age-at-death estimation using root dentine translucency (RDT) and periodontal retraction (PR) of single-rooted teeth in a worldwide sample. The sample includes 4810 teeth of 2559 individuals from 16 countries of America, Europe and Asia. Bias and inaccuracy between documented (DA) and estimated ages (EA) were calculated.

Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infections among sexual assault victims referred to three French clinical forensic units.

Background: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections are the most common bacterial sexually transmitted infections (STIs) worldwide. These STIs are frequently asymptomatic, which often delays diagnosis and treatment with the risk of serious long-term complications. Current French recommendations call for targeted screening of populations considered to be at risk, including victims of sexual assault.

Applicability of Cameriere's third molar maturity index on orthopantomograms and computed tomography scans from a French population.

Cameriere developed a method on orthopantomograms (OPG) to assess adult age of 18 years based on the relationship between age and the third molar maturity index I3M. The aim of this study was to evaluate whether Cameriere's method could be applied to computed-tomography scans (CT-scans) from a population of French juveniles and young adults and compare the results obtained from OPG of the same individuals. Our sample comprised 200 examinations that had been performed at the radiological department of a French University hospital between 2007 and 2020.

Fatal bowel perforation caused by ingestion of high-powered magnets in a 6-year-old boy.

Foreign body ingestion in children is a frequent cause for medical consultation. Although most foreign bodies are spontaneously eliminated from the gastrointestinal tract, life-threatening complications such as gastrointestinal obstruction or perforation can occur. We report the case of a 6-year-old boy who died 2 days after the onset of nausea and abdominal pain, with no foreign body ingestion witnessed or reported in the previous days.

Age assessment in unaccompanied minors: assessing uniformity of protocols across Europe.

Age assessment of migrants is crucial, particularly for unaccompanied foreign minors, a population facing legal, social, and humanitarian challenges. Despite existing guidelines, there is no unified protocol in Europe for age assessment.The Forensic Anthropology Society of Europe (FASE) conducted a comprehensive questionnaire to understand age estimation practices in Europe.

Teledentistry and Forensic Odontology: Qualitative Study on the Capacity of Implementation.

The postmortem identification of people without an identity is performed either by using DNA, dental charts, or fingerprints (until advanced decomposition prevents their study). The lack of forensic dentists who can conduct identifications lead us to reflect on the use of digital technology in this area. The aim of this study was to validate the organizational capacity of using teledentistry for the identification of bodies in a forensic medicine department.

Multicentric case series of scuba diving fatalities: The role of intracardiac gaseous carbon dioxide in the forensic diagnosis.

Scuba diving fatalities post-mortem diagnosis presents a higher level of forensic complexity because of their occurrence in a non-natural human life environment. Scuba divers are equipped with diving gas to breathe underwater. It is essential for them to be fully trained in order to be able to manage their dive safely despite the varying increase of ambient pressure and temperature decrease.

Influence of the toxicological status on the diagnosis of fatal drowning.

Drowning is the leading cause of death by accident of everyday life in people under 25 years of age. Xenobiotics are frequently involved in drowning cases but their influence on the diagnosis of fatal drowning has not been studied so far. This preliminary study aimed to assess the influence of an alcohol and/or a drug intoxication on the autopsy signs of drowning, and on the results of diatom analyses in drowning deaths.

Influence of the ear temperature range on the measurement bias between an infrared thermometer and a reference probe for post-mortem interval determination.

The aim of this study was to assess the influence of the post-mortem outer ear temperature (OET) on the measurement bias previously observed for short post-mortem intervals (PMI) between a commercially available infrared thermometer and a reference metal probe thermometer. To that end, 100 refrigerated bodies were added to our initial cohort to investigate lower OET. In contrast to our previous findings, a very good concordance was noted between both methods.

Characterization of Domestic Violence among Patients Consulting a French Psychiatric Emergency Department.

The aim of the present study was to identify the prevalence of domestic violence among patients attending a French psychiatric emergency department and its association with psychiatric disorders. This retrospective study was performed, including all patients examined in the psychiatric emergency department of the Lapeyronie University Hospital of Montpellier (France) in the daytime from 1 July 2021 to 31 October 2021. A total of 152 patients were eligible during this study period.

Age Estimation in 0-8-Year-Old Children in France: Comparison of One Skeletal and Five Dental Methods.

Age estimation in juveniles is a critical procedure in judicial cases for verification of imputability or for civil reasons when adopting children. Several methods based both on skeletal and dental growth have been performed and applied on different populations; nevertheless, few articles have compared different methods in order to test their reliability in different conditions and age ranges, and this is a clear obstacle in the creation of common guidelines for age estimation in the living. A comparison of five dental methods (Anderson, Ubelaker, Schour and Massler, Gustafson and Koch, Demirjian) and one skeletal method (Greulich a Pyle atlas) was performed on a population of 94 children aged between 0 and 8 years.

Forensic age assessments of alleged unaccompanied minors at the Medicolegal Institute of Montpellier: a 4-year retrospective study.

Background: As many other European countries, France has to deal with a growing number of migrants including some who contend age minority entitling them to benefits and privileges reserved for children within the context of legal proceedings. In case of doubtful minority, medical examinations may be carried out to assess skeletal and dental age. Our objective was to analyse the age assessments regarding individuals of doubtful minority assertion at the Medico-legal Institute of the University Hospital of Montpellier since 2018.

[Forensic autopsies and pathological examination: Current practice in Montpellier's jurisdiction. A retrospective study of 630 autopsies].

Introduction: In France, pathological examination is not systematically required in forensic autopsies. The factors affecting the decision to carry out a pathological expertise have not yet been defined. The aim of this study was to describe in which conditions a pathological expertise was required after forensic autopsy by the high court of Montpellier.

Teledentistry and forensic odontology: Cross-sectional observational comparative pilot study.

Unlabelled: Forensic dentistry is the branch of forensic science concerned with the study of teeth and jaws. To facilitate the work of experts, new comparative identification tools are emerging, with digital techniques such as the intra-oral camera, which are revolutionising current techniques in forensic dentistry.

Objective: The aim of this study is to evaluate the diagnostic quality of the post-mortem odontogram carried out remotely via a video of the oral cavity using an intra-oral camera.

Cytokines as new biomarkers of skin wound vitality.

Background: The diagnosis of skin wound vitality is currently based on standard histology, but histological findings lack sensitivity in case of a short survival time. New reliable biomarkers of vitality are therefore strongly needed. We assessed the ability of 10 candidate cytokines (IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, TNF-α) to discriminate between vital and early post-mortem wounds.

Estimation of the time since death based on body cooling: a comparative study of four temperature-based methods.

The estimation of the time since death is an important task in forensic medicine that mainly relies on body cooling in the early post-mortem period. The rectum has been traditionally used to determine the central core temperature after death, though the external auditory canal has been proposed as an alternative site by several authors. The objective of this study was to assess the ability of four body temperature-based methods (Henssge's rectal nomogram, Henssge's brain nomogram, and Baccino's both interval and global formulae based on ear temperature) to estimate the post-mortem interval (PMI).

Is infrared thermometry suitable for the determination of the time since death based on ear temperature? A comparative study of two measurement methods.

Infrared thermometry has been proposed as an interesting alternative to probe thermometers for recording ear temperature in cadavers to estimate the postmortem interval (PMI), but it has still to be validated in this setting. Our objective was to compare the performance of an infrared thermometer to that of a reference probe thermometer for measuring ear temperature. Temperature measurements were performed on 100 cadavers (mean PMI: 4.

Usefulness of a blood glucose and ketone monitoring device as a screening tool for lethal diabetic ketoacidosis.

Diabetic ketoacidosis (DKA) is a frequent and life-threatening complication, whose diagnosis remains challenging in forensic practice. We aimed at assessing the performance of a commercially available blood glucose and ketone monitoring device (BGMD) in measuring glucose and ketone levels in post-mortem vitreous (VH) and blood samples, in order to determine if such a device can be used for screening lethal cases of DKA at autopsy. VH and blood samples were collected in cases of unexplained causes of death at autopsy.

Epidemiological survey in a day care center following toddler sudden death due to human metapneumovirus infection.

We report the sudden death of a 33-month-old child owing to acute respiratory distress syndrome due to human metapneumovirus (hMPV) infection. Of 30 children attending the same day care centre, 26% and 59% had hMPV and multiple infections, respectively; three of six children with pneumonia had a diagnosis of hMPV. hMPV infection is common in childhood viral co-infections but it can cause sudden death.

Biochemical markers of time since death in cerebrospinal fluid: A first step towards .

The accurate estimation of the time of death is a challenge in forensic medicine, as the methods routinely used to assess the postmortem interval (PMI) are far from being precise. Over the past decades, biochemical methods have been implemented on postmortem samples to improve the precision of PMI estimation. Studies have focussed on the biochemical profiles of closed compartment body fluids, as they are preserved longer than blood after death and are thus subject to confined postmortem chemical changes.
