Patient's last wish: organ donation after euthanasia. What conditions should be met to fulfill it?

Abstract: Organ donation after euthanasia (ODE) is a complex procedure involving the patient, the family, and the medical staff. Most organ donations occur from patients declared brain dead, and healthcare professionals rely on surrogate decisions, or the possible expression of ante-mortem will. Organ donation from deceased individuals is thus feasible under rigorous conditions, while direct donation after euthana-sia is not possible. The scientific community has not reached a shared conclusion. It is also difficult to quantify the number of patients who would be medically eligible to donate organs after euthanasia. In keep-ing with the core the principle of self-determination, any decision to undergo euthanasia (with or without organ donation) must be voluntary and not influenced by external pressures. For this reason, the physician should avoid informing the patient about the possibility of donating their organs before their request for euthanasia is evaluated. Just as noteworthy is the issue of healthcare providers' conscientious objec-tion and the receiving patient's right to know whether the transplanted organs come from a subject who underwent euthanasia. Finally, the patient who requests to end their life does so primarily because they are tormented by unbearable suffering and often expresses, as a last wish, the desire to exercise their free will regarding their own body. Organ donation after euthanasia would therefore seem to reinforce patient autonomy and self-esteem, thus giving a different meaning to their inevitable death, which is useful in saving the lives of others.

Artificial intelligence and future perspectives in Forensic Medicine: a systematic review.

Objective: Artificial intelligence (AI) is the ability of a computer machine to display human capabilities such as reasoning, learning, planning, and creativity. Such processing technology receives the data (already prepared or collected), processes them, using models and algorithms, and answers questions about forecasting and decision-making. AI systems are also able to adapt their behavior by analyzing the effects of previous actions and working then autonomously. Artificial intelligence is already present in our lives, even if it often goes unnoticed (shopping networked, home automation, vehicles). Even in the medical field, artificial intelligence can be used to analyze large amounts of medical data and discover matches and patterns to improve diagnosis and prevention. In forensic medicine, the applications of AI are numerous and are becoming more and more valuable. Method: A systematic review was conducted, selecting the articles in one of the most widely used electronic databases (PubMed). The research was conducted using the keywords "AI forensic" and "machine learning forensic". The research process included about 2000 Articles published from 1990 to the present. Results: We have focused on the most common fields of use and have been then 6 macro-topics were identified and analyzed. Specifically, articles were analyzed concerning the application of AI in forensic pathology (main area), toxicology, radiology, Personal identification, forensic anthropology, and forensic psychiatry. Conclusion: The aim of the study is to evaluate the current applications of AI in forensic medicine for each field of use, trying to grasp future and more usable applications and underline their limitations.

Consequences of COVID-19 restrictions on adolescent mental health and drug abuse dynamics.

The COVID-19 pandemic has hit elderly people the hardest in terms of severity and mortality. However, it is also evident that children and adolescents have been significantly impacted and experienced major disruptions in their lives. The psychological, mental, and developmental repercussions have been major and have led to a reshaping of drug abuse dynamics and substance addiction. The authors have outlined a narrative review of the major issues affecting adolescents and their mental well-being by clarifying the lingering effects and pandemic aftermath, especially on drug abuse, developmental aspects, and behavioral addiction. The unique traits of adolescent risk factors have been outlined, in order to identify areas to be prioritized for future strategies. Possible repercussions on juvenile crime linked to social estrangedness and disrupted interactions have been briefly explored as well. All such aspects are highly meaningful and relevant from a medicolegal perspective as well. The looming mental health crisis involving youngsters will have to be confronted by fine-tuning and optimizing mental health care services, building on current experiences, raising awareness, and eliminating the stigma that often comes with mental issues. Healthcare systems should look at the current scenario as an opportunity to improve care delivery to eliminate access inequalities and stigmatization of mental issues and raise awareness for the benefit and well-being of all. Similarly, law enforcement, lawmakers, and the judiciary will have to account for such factors, too, as will economic policy-makers. In that regard, a set of defining criteria has been framed in order to provide a degree of objectivity when meeting the unique challenges of the pandemic for youth mental health, in a comprehensive and tailored fashion.

Obstetric Violence in Italy: From Theoretical Premises to Court Judgments.

Introduction: Historical mistreatment and violence directed toward women's bodies extend to the field of medicine, and obstetric and gynecological practices are not immune to such misconduct. Obstetric violence (OV) refers to actions involving disrespectful, abusive, or coercive treatment directed at pregnant and birthing women. This includes institutional and personal attitudes that lead to the violation of women's autonomy, human rights, and sexual and reproductive health. Despite various international legislative initiatives and recommendations from the World Health Organization (WHO) addressing disrespectful and abusive treatment, OV is still poorly known to Italian public opinion. This study aims to investigate whether the concept of OV has been conversely assimilated in judicial decisions. Materials and methods: A retrospective analysis was conducted to scrutinize judgments in Italy until June 2023 related to OV. The Italian legal database 'De Jure Giuffrè', which collects sentences by various Courts, and the terms 'obstetric' and 'violence' as keywords were used for the research. Results: The full-text revision of the results (n. 41 sentences) al-lowed the selection of 5 eligible contributions covering the following issues: Informed Consent, Kristeller maneuver, Vaginal Birth After Cesarean (VBAC), Acceleration of childbirth without indication, and Episiotomy. The analysis of individual judgments was complemented by an examination of the key issues involved. Conclusions: The reviewed judgments frequently seemed to be grounded in technical aspects and inclined towards a predominant evaluation of childbirth outcomes. However, some encouraging aspects emerged, particularly in terms of attention to the female body, acknowledgment of consequences within the intimate-relational dimension, and a commitment to the principle of self-determination through the provision of free and informed consent. Ensuring the psychophysical well-being of women and unborn children, fostering positive interactions between pregnant women and medical staff, and actively working to reduce the grounds for litigation are among actual emerging priorities in healthcare. In this sense, fundamental elements include the implementation of continuous staff training and education as well as a focus on promoting the self-determination of women, leveraging new technologies for this purpose, and ensuring legal protection of their rights.

Consensus Paper: Neurophysiological Assessments of Ataxias in Daily Practice.

The purpose of this consensus paper is to review electrophysiological abnormalities and to provide a guideline of neurophysiological assessments in cerebellar ataxias. All authors agree that standard electrophysiological methods should be systematically applied in all cases of ataxia to reveal accompanying peripheral neuropathy, the involvement of the dorsal columns, pyramidal tracts and the brainstem. Electroencephalography should also be considered, although findings are frequently non-specific. Electrophysiology helps define the neuronal systems affected by the disease in an individual patient and to understand the phenotypes of the different types of ataxia on a more general level. As yet, there is no established electrophysiological measure which is sensitive and specific of cerebellar dysfunction in ataxias. The authors agree that cerebellar brain inhibition (CBI), which is based on a paired-pulse transcranial magnetic stimulation (TMS) paradigm assessing cerebellar-cortical connectivity, is likely a useful measure of cerebellar function. Although its role in the investigation and diagnoses of different types of ataxias is unclear, it will be of interest to study its utility in this type of conditions. The authors agree that detailed clinical examination reveals core features of ataxia (i.e., dysarthria, truncal, gait and limb ataxia, oculomotor dysfunction) and is sufficient for formulating a differential diagnosis. Clinical assessment of oculomotor function, especially saccades and the vestibulo-ocular reflex (VOR) which are most easily examined both at the bedside and with quantitative testing techniques, is of particular help for differential diagnosis in many cases. Pure clinical measures, however, are not sensitive enough to reveal minute fluctuations or early treatment response as most relevant for pre-clinical stages of disease which might be amenable to study in future intervention trials. The authors agree that quantitative measures of ataxia are desirable as biomarkers. Methods are discussed that allow quantification of ataxia in laboratory as well as in clinical and real-life settings, for instance at the patients' home. Future studies are needed to demonstrate their usefulness as biomarkers in pharmaceutical or rehabilitation trials.

Renal tuberculosis: a case report.

Tuberculosis or TB (tubercle bacillus) remains a major public health problem in developing countries. Over the last decades extrapulmonary locations of the disease have become more frequent due to the increased prevalence of acquired immune deficiency syndrome and the increase number of organ transplants. The urogenital localization represents about 27% of all extra-pulmonary localizations of TB and may be due either to a disseminated infection or to a primitive genitourinary localization. The majority of patients, has pyuria, sometimes with hematuria. The diagnosis of urinary tuberculosis is based on the finding of pyuria in the absence of infection by common bacteria. The initial medical treatment includes isoniazide, rifampicin, pyrazinamide, ethambutol and streptomycin. This disease should be suspected in patients with unexplained urinary tract infections, especially if immunocompromised and/or coming from endemic areas.

[Radon risk in healthcare facilities: environmental monitoring and effective dose]. / Il rischio radon in ambienti sanitari: monitoraggio ambientale e dose efficace.

BACKGROUND: Radon, the second cause of lung cancer after smoking (WHO- IARC), is a natural, radioactive gas, which originates from the soil and pollutes indoor air, especially in closed or underground spaces. OBJECTIVES: The purpose of this study was to determine the concentration of radon gas, its effective dose, and the measurement of microclimatic degrees C; U.R. % and air velocity in non-academic intensive care units of public hospitals in the Naples area. METHODS: The annual average concentrations of radon gas were detected with EIC type ionization electret chambers, type LLT with exposure over four 3-month periods. RESULTS: The concentrations varied for all health facilities between 186 and 1191 Bq/m3. Overall, the effective dose of exposure to radon gas of 3mSv/a recommended by Italian legislation was never exceeded. CONCLUSIONS: The concentration of radon gas showed a decreasing trend starting from the areas below ground level to those on higher floors; such concentrations were also influenced by natural and artificial ventilation of the rooms, building materials used for walls, and by the state of maintenance and improvements of the building (insulation of floors and walls). The data obtained confirmed the increased concentration of radionuclides in the yellow tuff of volcanic origin in the Campania Region and the resulting rate of release of radon gas, whereas the reinforced concrete structure (a hospital located on the hillside), which had the lowest values, proved to provide good insulation against penetration and accumulation of radon gas.

Generalized dystonia and striatal calcifications with lipoid proteinosis.

Lipoid proteinosis (LP) is an autosomal recessive disease that typically presents with papular, verrucous, poxlike, or acneiform scars and lesions and hoarseness. LP was recently mapped to the 1q21 locus and shown to result from mutations in the extracellular matrix protein 1 gene (ECM1). Epilepsy, mental retardation, and hippocampal calcifications can occur. The authors describe a patient with generalized dystonia caused by striatal calcifications.

[Irritative midline and parasaggital foci: a clinical and electroencephalographic correlation]. / Focos irritativos parassagitais e de linha média: correlação clínico-eletrencefalográfica.

We report the clinical and electroencephalographic characteristics of thirteen patients with midline spikes (MS), parasaggital foci (PF), or both. Numerous clinical manifestations, including generalized tonic-clonic, complex partial and partial with secondary generalization could be demonstrated. The pattern of the epileptiform manifestation is unpredictable; however, we find generalized tonic-clonic seizure the commonest type (60%). Unfortunately, this data has no statistic value. Neurologic examination was normal in the majority of the patients. Regarding age, there is a marked predominance of children (84%) with MS and/or PF. Sleep constitutes the main activation method (73%) in the search for this kind of epileptiform activity. In conclusion, although the incidence of the MS/PF is quite low (0.4%), the high epileptogenic potential (70%) of them justifies a careful and adequate evaluation of these regions. Special attention must be paid to the normal sleep complexes, mainly in children, which sometimes can mimic true epileptiform activity.

A renal inhibitor to hepatic erythropoietin [Ep] production.

Evidence is presented for the existence of a factor in renal venous blood, evoked by subtotal hepatectomy (hepx), which inhibits the production of Ep in nephrectomized (nephrx) rats exposed to hypoxia. Significant inhibitory activity is not observed in blood obtained from sites other than the renal vein. This inhibitory effect is believed to be due to the action of a specific renal inhibitory factor (RIF) which reduces the extrarenal (hepatic) Ep response to hypoxia indirectly, by decreasing the production or effectiveness of an antagonistic liver principle, the hepatic erythropoietic factor (HEF). The HEF has previously been shown to augment hepatic Ep production following hypoxia in renally-deficient animals. The RIF has no anti-Ep action and its activity is not influenced by the accumulation of metabolic wastes. A mechanism for a renal-hepatic antagonism in the Ep response to hypoxia is hypothesized.
