Artificial intelligence in healthcare: an Italian perspective on ethical and medico-legal implications.

Artificial intelligence (AI) is a multidisciplinary field intersecting computer science, cognitive science, and other disciplines, able to address the creation of systems that perform tasks generally requiring human intelligence. It consists of algorithms and computational methods that allow machines to learn from data, make decisions, and perform complex tasks, aiming to develop an intelligent system that can work independently or collaboratively with humans. Since AI technologies may help physicians in life-threatening disease prevention and diagnosis and make treatment smart and more targeted, they are spreading in health services. Indeed, humans and machines have unique strengths and weaknesses and can complement each other in providing and optimizing healthcare. However, the healthcare implementation of these technologies is related to emerging ethical and deontological issues regarding the fearsome reduction of doctors' decision-making autonomy and acting discretion, generally strongly conditioned by cognitive elements concerning the specific clinical case. Moreover, this new operational dimension also modifies the usual allocation system of responsibilities in case of adverse events due to healthcare malpractice, thus probably imposing a redefinition of the established medico-legal assessment criteria of medical professional liability. This article outlines the new challenges arising from AI healthcare integration and the possible ways to overcome them, with a focus on Italian legal framework. In this evolving and transitional context emerges the need to balance the human dimension with the artificial one, without mutual exclusion, for a new concept of medicine "with" machines and not "of" machines.

The hunger strike in prison: bioethical and medico-legal insights arising from a recent opinion of the Italian national bioethics committee.

This contribution addresses some bioethical and medico-legal issues of the opinion formulated by the Italian National Bioethics Committee (CNB) in response to the dilemma between the State's duty to protect the life and health of the prisoner entrusted to its care and the prisoner's right to exercise his freedom of expression. The prisoner hunger strike is a form of protest frequently encountered in prison and it is a form of communication but also a language used by the prisoner in order to provoke changes in the prison condition. There are no rules in the prison regulations, nor in the laws governing the legal status of prisoners, that allow the conscious will of the capable and informed subject to be opposed and forced nutrition to be carried out. However, this can in no manner make therapeutic abandonment legitimate: the medical doctor should promote every action to support the patient. In the recent opinion formulated by the CNB it was remarked how self-determination is a central concept in human rights and refers to an individual's ability to make autonomous and free decisions about his or her life and body.

Home birth in Croatia - a medico-legal perspective today.

In Croatia, the model of obstetrics-midwifery management of childbirth in maternity hospitals is still in effect, and this is how > 99% of Croatian women give birth. However, in my view, midwives are still not sufficiently educated for completely independent work notwithstanding their university education. The Law on Midwifery defined the role of the midwife in home birth without, however, setting out other organisational-communication and professional provisions. Then it began with sporadic midwifery home births of a few per year, which grew quite rapidly, especially with the impact of the Covid-19 virus pandemic, to about 100 out of a total of about 38,000 births that are performed annually in the Republic of Croatia in maternity hospitals. Since the start of planned home births many bad perinatal outcomes have been recorded in hospital maternity wards who have admitted women after such deliveries. These include puerperal sepsis, protracted labour of several days, neglected protracted labour with perinatal asphyxia and aspiration of meconium amniotic fluid and resuscitation of the newborn (who later developed cerebral palsy), severe postpartum haemorrhage with obstetric shock and postpartum hysterectomy, episiotomy infection, and stillbirth at term pregnancy. Therefore, planned home birth in Croatia should now be regarded as an unsafe birth in extraordinary circumstances and the person who takes charge of it must be professionally prepared, educated and have numerous social skills. Most Croatian gynaecologists and obstetricians give support to midwives in their efforts to be professional and independent when at work, including the controlled and legal implementation of the planned home birth. We unreservedly support self-aware midwives to maintain their profession as highly ethical and professional as possible above the wishes of non-professionals who call for autonomy, so that we do not have to discuss such problems of malpractice of Croatian midwifery in the 21st century.

Molecular differentiation analysis of ten putative species of Fannia (Diptera: Fanniidae) collected in carrion-baited traps from Colombia.

The genus Fannia is the most representative of the Fannidae family of true flies with worldwide distribution. Some species are attracted to decomposing materials and live vertebrate animals, which makes them important in forensics, medical and veterinary fields. However, identifying Fannia species can be difficult due to the high similarity in the external morphology of females and limited descriptions and morphological keys. Herein, molecular markers could provide a complementary tool for species identification. However, molecular identification has still limited application since databases contain few data for neotropical species of Fannia. This study assessed the potential of two molecular markers, the COI-3' region and internal transcribed spacer 2 (ITS2), to differentiate 10 putative species of the genus Fannia from Colombia using distance-based and tree-based approaches. The partial ITS2 and/or COI-3' regions allowed molecular diagnosis of six species, while pairs of species Fannia colazorrensis + F. dodgei and F. laclara + F. aburrae are conflicting. Although these results might suggest that conflicting pair species are conspecific, consistent morphological differences between males do not support this hypothesis. The lack of differentiation at the nuclear and mitochondrial molecular markers for the conflicting species may be due to incomplete evolutionary lineage separation, hybridization, or introgression events. In addition, sexual selection on male morphological traits before species-specific differences in molecular markers emerge may partially explain the results. Our study provides a valuable dataset to identify and confirm some Fannia species molecularly. Further, they could be used to associate females and immature stages with their conspecifics as a baseline to deep into their biology, ecology, distribution and potential applications in forensic and medico-veterinary entomology.

Standardized Informed Consent Form for Clinicians Administering Platelet-Rich Plasma.

Introduction When it comes to medico-legal malpractice suits, lawyers and insurers tend to focus on informed consent documentation. Unfortunately, there is no standard protocol for obtaining informed consent for the use of platelet-rich plasma (PRP) injections, which might cause problems. This study aimed to mitigate this concern through the development of a standardized informed consent document for PRP injections, grounded in evidence-based practices. Materials and methods An examination of databases was conducted to explore the medico-legal ramifications associated with PRP injections, as well as the broader topic of informed consent, with a particular focus on the context of PRP injections. Moreover, interviews were carried out with healthcare providers and individuals who had received PRP injections within the preceding year, utilizing a semi-structured methodology. Results We developed an evidence-based informed consent document tailored for PRP injections. To guarantee its legal validity, the document underwent review by a legal specialist. Subsequently, our institutions implemented the finalized form for PRP injection procedures over one year. Conclusion A legally valid and evidence-based informed consent form for PRP injections would ensure patient's rights, and encourage open communication and transparency between them and the doctor. Moreover, if a lawsuit were to arise, it would serve as a critical document in the doctor's defense and withstand scrutiny from lawyers and the judiciary.

Patient characteristics of, and remedial interventions for, complaints and medico-legal claims against doctors: a rapid review of the literature.

BACKGROUND: It is uncertain if patient's characteristics are associated with complaints and claims against doctors. Additionally, evidence for the effectiveness of remedial interventions on rates of complaints and claims against doctors has not been synthesised. METHODS: We conducted a rapid review of recent literature to answer: Question 1 "What are the common characteristics and circumstances of patients who are most likely to complain or bring a claim about the care they have received from a doctor?" and Question 2 "What initiatives or interventions have been shown to be effective at reducing complaints and claims about the care patients have received from a doctor?". We used a systematic search (most recently in July 2023) of PubMed, Scopus, Web of Science and grey literature. Studies were screened against inclusion criteria and critically appraised in duplicate using standard tools. Results were summarised using narrative synthesis. RESULTS: From 8079 search results, we reviewed the full text of 250 studies. We included 25 studies: seven for Question 1 (6 comparative studies with controls and one systematic review) and 18 studies for Question 2 (14 uncontrolled pre-post studies, 2 comparative studies with controls and 2 systematic reviews). Most studies were set in hospitals across a mix of medical specialties. Other than for patients with mental health conditions (two studies), no other patient characteristics demonstrated either a strong or consistent effect on the rate of complaints or claims against their treating doctors. Risk management programs (6 studies), and communication and resolution programs (5 studies) were the most studied of 6 intervention types. Evidence for reducing complaints and medico-legal claims, costs or premiums and more timely management was apparent for both types of programs. Only 1 to 3 studies were included for peer programs, medical remediation, shared decision-making, simulation training and continuing professional development, with few generalisable results. CONCLUSION: Few patient characteristics can be reliably related to the likelihood of medico-legal complaints or claims. There is some evidence that interventions can reduce the number and costs of claims, the number of complaints, and the timeliness of claims. However, across both questions, the strength of the evidence is very weak and is based on only a few studies or study designs that are highly prone to bias.

Challenge of achieving truly individualised informed consent in therapeutic endoscopy.

Objective: Guidance covering informed consent in endoscopy has been refined in the UK following the obstetric case of Nadine Montgomery, and in light of updated General Medical Council guidance. All risks likely to be material to the patient must be explored, as well as alternatives to the procedure. Despite this, departments and endoscopists still struggle to meet the current standards. In this article, we explore the challenges encountered in achieving individualised consent in therapeutic endoscopy through real-life scenarios. Methods: Five realistic therapeutic endoscopy (hepatobiliary) scenarios are described, followed by presentation of possible or ideal approaches, with references related to existing literature in this field. Results: The vignettes allow consideration of how to approach difficult consent challenges, including anxiety and information overload, urgency during acute illness, failure to disclose the risk of death, the role of trainees and intraprocedural distress under conscious sedation. Conclusions: The authors conclude that a high degree of transparency is required while obtaining consent for therapeutic endoscopy accompanied by full documentation, involvement of relatives in nearly all cases, and clarity around the presence of trainees who may handle the scope. A greater focus on upskilling trainees in the consent process for therapeutic endoscopy is required.

A case of surgical site infection with severe spondylitis caused by Streptococcus gordonii in an adult healthy woman: how to apply medico-legal method to deny malpractice hypothesis in suspected healthcare-associated infection.

We describe a rare case of severe primary spondylitis caused by Streptococcus gordonii in a 45-year-old immunocompetent woman with no relevant comorbidities. The surgical site infection arose after a L4-L5 microdiscectomy and resulted in severe clinical disability. Allegations of possible negligence as the cause prompted a forensic review to clarify the original source and transmission of this uncommon pathogen, which dismissed its cause as due to malpractice during treatment.

Medico-Legal Implications of Video Recordings of Clinic Visits in Malpractice Claims Against Medical Providers.

OBJECTIVE: Although audio-video recordings of clinic visits improve patient satisfaction and recall, the associated presumed risk of increased malpractice claims limits their use. In this study, we identified whether video recording clinic visits was associated with increases in professional liability claims. METHODS: From 2015 to 2017, the institution's loss run was analyzed, and the rates of medical malpractice claims per physician-year were compared between physicians who used video recordings of clinic visits (V-RoCs) and those who did not. The term "users" was applied to all physicians whose mean percentage of patient visits with video recording was greater than the mean percentage for the practice overall. RESULTS: Over three years, 15,254 patients used V-RoCs. The use of video recordings for clinic visits increased at a rate of 23% per year. No association was found between video recordings and increased malpractice claims. The rate of all claims between users and nonusers did not differ significantly (P=0.66). Of seven paid claims or lawsuits from 2000 to 2017, none were against physicians who used video recordings. CONCLUSION: Video recording of patient-physician encounters was not associated with an increase in malpractice lawsuits. According to federal law, a patient can legally record a clinic encounter without physician consent, which has many ethical implications. Formalizing the recording process is beneficial for both parties and allows the resource to be used to its maximum potential.

The Labyrinthine Journey: Unveiling Obstacles in addressing Mental Health Challenges in Prisons and its Confluence with Medico-Legal and Pharmacological Perspectives.

This paper delves into the intricate realm of mental health issues within prisons including other correctional facilities, the intersectionality with legal and medical aspects, and the potential of pharmacology as a viable treatment modality. The prevalence and diverse array of mental disorders among incarcerated individuals are thoroughly examined, underscoring the imperative for all-encompassing interventions. The legal structure, hurdles encountered in delivering mental healthcare, and the indispensability of interdisciplinary cooperation are scrutinized. Furthermore, the effectiveness and moral implications of pharmaceutical interventions in correctional environments are deliberated upon. Conclusive suggestions are put forth to enhance mental healthcare provisions in prisons. The research paper endeavors to penetrate the labyrinthine complexities of mental health predicaments within correctional institutions, with a specific emphasis on the convergence of medico-legal facets and the plausible impact of pharmacological interventions. The study strives to elucidate the intricate nature of mental health challenges among incarcerated populations, considering the intricate interplay of socio-cultural, environmental, and psychological factors that contribute to their pervasiveness. By delving into these interconnected dimensions, the research aims to unlock prospective remedies capable of efficaciously meeting the mental health requisites of incarcerated individuals.

Sex differences and driving impairment related to psychoactive substances.

OBJECTIVE: The first aim of the study was to identify sex differences in the use of psychoactive substances among subjects with a previous driving under the influence (DUI) episode. The secondary objective was to propose specific strategies for medico-legal improvements. METHODS: This was a retrospective observational study that took place between June 1, 2019, and August 31, 2023. It was conducted on DUI subjects examined for reinstatement of their driver's license using an integrated medico-legal and toxicological approach. Ethyl glucuronide (EtG) and illicit psychoactive substances were determined from hair samples. We performed descriptive statistical analyses for the entire sample as well as separately by sex. Additionally, we conducted binary logistic regression analyses separately for males and females to identify protective/risk factors associated with previous road accidents and judgments of unfitness to drive due to excessive alcohol consumption (EtG ≥ 30 pg/mg). RESULTS: The study included 2,221 subjects, comprising 1,970 men and 251 women. Men exhibited a higher prevalence of tobacco, alcohol, and illicit psychoactive substance use. Women were more frequently co-users of alcohol and psychoactive substances and involved in road accidents at the time of DUI. Among the men, being married or having a partner was found to be a protective factor concerning past traffic accidents. For both sexes, a DUI episode with a blood alcohol concentration (BAC) exceeding 1.5 g/L or the co-ingestion of alcohol and drugs was identified as a risk factor for road accident involvement. For men, smoking more than 20 cigarettes per day and, for women, having a DUI episode with a BAC over 1.5 g/L were the main factors indicating unfitness to drive, as determined through high hair EtG levels (> 30 pg/mg). Women with a previous history of road accidents were less likely to have EtG levels of 30 pg/mg or more. CONCLUSIONS: The study confirmed sex differences in subjects with a previous DUI episode. A BAC exceeding 1.5 g/L or the simultaneous use of alcohol and drugs at the time of DUI necessitate careful assessment of both men and women seeking driver's license reinstatement. In women, a BAC exceeding 1.5 g/L is considered a risk factor for a subsequent judgment of unfitness to drive. The medico-legal assessment should also involve a thorough investigation of smoking habits in men, as these habits could be related to an increased risk of excessive alcohol consumption.

Child torture victimization: Review of criminal statutes and medico-legal issues.

A renowned group of pediatricians and an attorney with expertise in child abuse matters proposed a medical definition of intrafamilial child torture perpetrated by a caretaker in a landmark 2014 publication in the health sciences literature. Representing one of the most widely cited publications on non-politically motivated child torture to date, this medical definition encompassing physical abuse, psychological abuse, deprivation, and neglect characterizing child torture has been broadly recognized and accepted by multidisciplinary professionals across medical, child welfare, and criminal justice sectors. While the medical community's efforts aimed to compel legislative changes, including adoption of explicit torture-specific statutes that would enable criminal justice system responses reflective of abuse severity, subsequent legal analyses have revealed tremendous variability in criminal investigations, prosecution, sentencing, and case outcomes. In this discussion piece, medico-legal issues relevant to intrafamilial child torture case prosecution are reviewed. The impact of the established medical definition on jurisdictional legal approaches and unique case challenges related to longitudinal nature of abuse, frequent psychological injury, and victim-perpetrator dynamics are explored in depth. Utilizing available legal research platforms, investigative information, health sciences literature, and prosecutor self-report, existing child torture statutes and case outcomes were compared with focus on perpetrator, victim, socio-environmental, and community influence on legal outcome. Prosecutorial challenges facing jurisdictions lacking child torture statutes are discussed with emphasis placed on the critical role played by the medical community to support diagnosis of physical and emotional impacts to the child. Finally, the process by which states can establish a jurisdictional torture statute are suggested.

Day-of-the-week variation of sudden unexpected cardiac death.

Background: There has been some controversy about the day-of-the-week (septadian) variation of unexpected sudden cardiac death (SCD). Methods: We evaluated the incidence of unexpected SCD on different days of the week in a consecutive series of 5869 SCD victims from Northern Finland [the FINGESTURE study (Finnish Genetic Study of Arrhythmic Events)]. As it is mandatory in Finland, a medico-legal autopsy was performed on all unexpected sudden death victims. The autopsies were performed between the years 1998-2017. Results: The mean incidence of unexpected SCD was higher at weekends (during the days from Friday to Sunday, peaking on Saturday) than during the days from Monday to Thursday (8.54 ± 0.72 vs. 7.22 ± 0.19 SCDs per day of the week per 100,000 inhabitants per year, p < 0.001). Regardless of sex or ischemic versus non-ischemic etiology of SCD, the distribution of the occurrence of SCD among the days of the week was similar compared with the whole SCD cohort. Conclusion: The incidence of unexpected SCD was highest at weekends (during the days from Friday to Sunday, peaking on Saturday).

Organ procurement in forensic deaths: A retrospective analysis of the Italian context with a focus on the Puglia Region virtuous experience.

Organ transplantation is one the most important contributions of modern medicine to society since it provides a unique therapy for terminal organ failure. However, the development of this therapeutic approach is hindered by the limited organ supply. In Italy, organ procurement requires a multidisciplinary medical-surgical approach in which legal medical doctors (LMDs) are generally tasked with ascertaining the reality of death. Sometimes, a medico-legal report is required when the deceased's family deny their consent to the organs and tissues removal from a potential deceased donor. LMDs can also be appointed by law to carry out post-mortem examinations of potential deceased donors. In these cases, the public prosecutors' interest in preserving the corpse integrity for forensic purposes seems to conflict with the ethical-humanitarian interest in promoting, at most, the opportunity to donate; however, a LMD can act as a mediator and allow both goals. This paper aims to illustrate the Apulia Region experience in reconciling the justice interests with those of a culture promoting deceased organ and tissue donation. It has been pursued by analyzing the virtuous regional organ procurement trend in forensic deaths before and after a crucial 2015 initiative, comparing the results with the national ones, and contextualizing them in the relevant literature to show systemic strengths and weaknesses and inform future Italian policy development.

Appendiceal duplication: a case report of horseshoe-shaped appendix and implications for patient safety.

Appendiceal anomalies, particularly double appendices, are rare and mainly detected during non-appendiceal surgery in adults. Misrecognizing them can have serious consequences, both clinically and legally. It is critical that surgeons pay attention to the anatomical variations of the vermiform appendix, and always consider the possibility of duplicated appendix when diagnosing a right iliac fossa pain. Misdiagnosis can lead to life-threatening medical complications for the patient, with medico-legal implications.

Medico-legal risk of infectious disease physicians in Canada: A retrospective review.

Objective: There is little known about the medico-legal risk for infectious disease specialists in Canada. The objective of this study was to identify the causes of these medico-legal risks with the goal of improving patient safety and outcomes. Methods: A 10-year retrospective analysis of Canadian Medical Protective Association (CMPA) closed medico-legal cases from 2012 to 2021 was performed. Peer expert criticism was used to identify factors that contributed to the medico-legal cases at the provider, team, or system level, and were contrasted with the patient complaint. Results: During the study period there were 571 infectious disease physician members of the CMPA. There were 96 patient medico-legal cases: 45 College complaints, 40 civil legal matters, and 11 hospital complaints. Ten cases were associated with severe patient harm or death. Patients were most likely to complain about perceived deficient assessments (54%), diagnostic errors (53%), inadequate monitoring or follow-up (20%), and unprofessional manner (20%). In contrast, peer experts were most critical of the areas of diagnostic assessment (20%), deficient assessment (10%), failure to perform test/intervention (8%), and failure to refer (6%). Conclusion: While infectious disease physicians tend to have lower medico-legal risks compared to other health care providers, these risks still do exist. This descriptive study provides insights into the types of cases, presenting conditions, and patient allegations associated with their practice.

Objectif: On sait peu de choses sur les risques médico-légaux auxquels sont exposés les spécialistes des maladies infectieuses au Canada. L'objectif de cette étude est de cibler les causes qui sous-tendent ces risques et, ce faisant, d'améliorer la sécurité et l'issue clinique des patients. Méthodes: Une analyse rétrospective sur 10 ans des dossiers médico-légaux conclus par l'Association canadienne de protection médicale (ACPM) entre 2012 et 2021 a été effectuée. Des experts ont été consultés pour cerner les facteurs à l'origine des dossiers médico-légaux en question, que ce soit à l'échelle des prestataires de soins, des équipes ou du système, et ces facteurs ont été mis en parallèle avec les plaintes des patients. Résultats: Au cours de la période de l'étude, 571 médecins membres de l'ACPM étaient spécialisés dans le traitement des maladies infectieuses. Quatre-vingt-seize dossiers médico-légaux portant sur des patients ont été recensés : 45 plaintes auprès d'un Collège, 40 poursuites au civil et 11 plaintes intrahospitalières. Un préjudice grave ou un décès a été constaté dans dix dossiers. Les motifs de plainte les plus répandus chez les patients étaient les évaluations perçues comme déficientes (54 %), les erreurs de diagnostic (53 %), une surveillance ou un suivi inadéquats (20 %) et un comportement non professionnel (20 %). En revanche, les experts consultés se sont surtout montrés critiques à l'égard des évaluations diagnostiques (20 %), des évaluations déficientes (10 %), du manquement à faire un test ou une intervention (8 %) et du manquement à orienter quelqu'un vers une ou un collègue (6 %). Conclusion: Les risques médico-légaux des médecins spécialisés dans le traitement des maladies infectieuses sont généralement moindres que ceux d'autres professionnels de la santé. Néanmoins, ces risques existent. Cette étude descriptive jette un éclairage sur le type de dossiers associés à la pratique de ces médecins, sur les motifs de consultation et sur les allégations formulées par les patients. Summary: Infectious disease (ID) physicians play a vital role in managing a broad spectrum of illnesses, from common infections to complex conditions, through rapid disease detection, effective treatment, preventive measures, and appropriate use of antimicrobial agents. ID doctors generally have a lower risk of complaints and lawsuits compared to other types of doctors. However, these risks do still exist and are important to consider.Our research team conducted a review of medico-legal cases over a 10-year period (2012­2021) involving ID physicians, with the goal of identifying why these problems occurred and how physicians might avoid them in the future. We examined why patients complained, what the types of diseases were, and the extent of patient harm. We also looked at which other types of doctors were most often involved in these cases.Most of the cases were either complaints made to a college (47%) or civil legal cases (42%). The rate of cases remained relatively stable over the study period. Twenty percent of complaints were linked to conditions of the bones, muscles, and connective tissue, such as osteomyelitis and septic arthritis. More than half of the patients who complained specifically mentioned concerns with the physician's assessment or a diagnostic error. In contrast, when expert physicians reviewed these cases, they only identified diagnostic errors in 20% of cases, and deficient assessments in 10% of cases.This research is important for two reasons. First, it may help to create a clearer picture of the current medico-legal landscape within the ID specialty. Second, by identifying areas of potential risk, it can guide the development of strategies to reduce these risks, thereby improving patient safety and trust in health care providers.

On legal guardianship: An exploratory assessment of knowledge, attitudes and practices of resident physicians.

BACKGROUND: Clinicians encounter patients under legal guardianship. We aimed to assess the knowledge, attitudes and practices (KAP) on legal guardianship in residents. METHODS: A KAP pilot survey about legal guardianship was developed by an interdisciplinary medicine-law-public health team and was distributed via institutional email to internal medicine, psychiatry, and neurology residents in a single academic institution. RESULTS: Of the 172 invited residents, 105 (61%) responded and 102 surveys were included in the final analysis. Most respondents (58% women; internal medicine 73%, neurology 15%, psychiatry 12%) had attended 42 medical schools from 16 countries and had heard about guardianship (88%), but only 23% reported having received training on guardianship during medical school or residency. The vast majority (97%) understood the intended benefit of guardianship, but only 22.5% reported knowing that guardianship removed an individual's decision-making rights. Nearly half (47%) of respondents reported never having asked for documentation to prove that an individual was a patient's guardian, and only 15% expected to see a court order as proof of guardianship status. CONCLUSIONS: Although most residents intuitively understood the intended benefit of guardianship, they did not understand its full implications for clinical practice. Training interventions are warranted.

The complementarity of phosphatidylethanol in whole blood and ethyl glucuronide in hair as biomarkers for the monitoring of alcohol use.

Monitoring long-term alcohol use and/or abstinence is essential in clinical and medico-legal cases. Analysis of ethyl glucuronide (EtG) in hair provides information on alcohol consumption over several months. However, there is a lag time between ethanol consumption, incorporation of EtG in the hair bulb and hair growing out of the scalp. Phosphatidylethanol (PEth) 16:0/18:1 analysis in whole blood has a detection window of 2-4 weeks, allowing for the detection of recent alcohol consumption. In this study, 2340 paired samples (of hair and venous whole blood from 1170 individuals) were analysed for EtG in hair (hEtG) and PEth 16:0/18:1 in venous whole blood. PEth 16:0/18:1 and hEtG results were subdivided into three categories according to the consensus of SoHT (hEtG) and PEth-NET (PEth): abstinence/low, moderate or excessive alcohol consumption. For hEtG analysis, 446 individuals presented abstinence/low alcohol consumption, of which 2% were classified as excessive alcohol users through PEth 16:0/18:1 analysis. This suggests excessive alcohol consumption in the weeks before sample collection. Out of 483 individuals classified as heavy alcohol users based on hEtG analysis, 14% showed abstinence/low alcohol consumption for PEth 16:0/18:1 analysis, implying that these subjects stopped drinking 2-4 weeks before sample collection. Our results show that the analysis of the two different biomarkers can lead to a more accurate categorisation of individuals. Therefore, we emphasize that for the retrospective investigation of alcohol use, it is necessary to include two alcohol use biomarkers with different detection windows.

Trauma and sporadic desmoid tumor development: An approach toward real incidence and aspects of causality.

OBJECTIVES: The development of desmoid tumors (DT) is associated with trauma, which is an aspect with medicolegal relevance. The objective of this study was to analyze the proportion and type of trauma (surgical, blunt/fracture, implants), its lag time, and mutations of the CTNNB1 gene in patients with sporadic DT. METHODS: We analyzed a prospectively kept database of 381 females and 171 males, median age at disease onset 37.7 years (females) and 39.3 years (males) with a histologically confirmed DT. Patients with germline mutation of the APC gene were excluded. Details of the history particularly of traumatic injuries to the site of DT were provided by 501 patients. RESULTS: In 164 patients (32.7%), a trauma anteceding DT could be verified with a median lag time of 22.9 months (SD, 7.7 months; range, 9-44 months). A prior surgical procedure was relevant in 98 patients, a blunt trauma in 35 patients, a punctuated trauma (injections, trocar) in 18 patients, and site of an implant in 10 patients. In 220 patients, no trauma was reported (43.9%), and 58 females (11.6%) had a postpregnancy DT in the rectus abdominis muscle. In 42 patients (8.4%), data were inconclusive. The distribution of mutations in the CTNNB1 gene (codon 41 vs. 45) was similar in patients with and without a history of trauma before DT development. CONCLUSIONS: A significant subgroup of patients suffers from a trauma-associated DT, predominantly at a prior surgical site including implants to breast or groin, accounting for 77.9% of the cases, whereas blunt trauma was responsible in 22.1%. We found no data to support that trauma-associated DT have different molecular features in the CTNNB1 gene.

The posterior interosseus artery flap (piaf) in reconstructive surgery of the hand: strategies of use and medico-legal implications.

Background and aim: The fascio-cutaneous posterior interosseus artery flap (PIAF) is used in hand reconstruction, especially to repair skin or tissue defects such as burn injuries, open fractures, gunshot wounds or traumatic amputations. The aim of this study is to examine the anatomical features of this flap, to describe the surgical harvesting technique and the difficulties associated with the dissection. Methods: From January 2016 to January 2022, we performed PIAF in 10 patients (3 women and 7 men) with a mean age of 28 years (range 22-44). This flap is taken from the back of the forearm, between the extensor carpi ulnaris (ECU) muscle and the extensor digitorum common (EDC) muscle. Results: We analyzed retrospectively our patients indicating the failures of this reconstructive surgery, the complications that have arisen and the results using DASH score with the related clinical and medico-legal implications. Conclusions: Due to its location and structure, PIAF is one of the most versatile fascio-cutaneous flaps in upper limb reconstructive surgery and can be used to reconstruct parts of the hand, wrist, or elbow, allowing to restore limb function and improve the quality of life of patients even if there could be some medico-legal implications.
