Gender Violence During the Three Ages of Life and the Impact of the Covid-19 Pandemic: A Review.

Children, women, and older people suffer different types of violence, which appears to have been exacerbated during the COVID-19 pandemic and the relative lockdown. The aim of this study is to analyze the literature about gender violence and abuse in the different ages of life and during the COVID-19 lockdown. Data were obtained from an electronic literature search using various online sources such as PubMed, Google Scholar, Science Direct and Web of Science. The terms "child abuse" were the most frequently used, followed in frequency by "gender violence," "femicide," and, lastly, "elderly abuse." The first studies considered gender-based violence as a purely physical problem, then, progressively, the analysis focused on the psychological point of view of the issue. There was a greater number of studies in 2020 about violence in comparison with previous years. The social and scientific attention to gender-based violence appeared to be very poor, especially in the case of older people abuse. It is necessary to increase general attention to the topic to correctly identify each form of abuse and to be able to take care of the subjects most at risk.

Pediatric poisoning management: How clinical practice can benefit from forensic approach.

Pediatric population represents the most vulnerable and at risk for unintentional poisoning, with children younger than 6 years old accounting for nearly half of poison exposures. Poisoning is a time-dependent emergency. The need to reach a scientific agreement on diagnostic protocol and treatment seems to be crucial to reduce morbidity and mortality. Starting from a buprenorphine pediatric intoxication case, this article highlights the limits and pitfalls of the traditional diagnostic approach. Diagnosis of drug intoxication was achieved after several days when an in-depth diagnostic investigation became necessary and complete forensic toxicological analyses were performed. Results evidenced an alarming lack of an unequivocal diagnostic protocol in case of suspect intoxication in structures not provided with a forensic toxicological service/unit. Collection of biological specimens according to forensic protocols at hospitalization plays a paramount role in the definitive diagnosis of intoxication. A diagnostic algorithm that focuses on medical history and biological specimen collection timing is herein proposed, in order to unify emergency approaches to the suspected poisoned child.

Vehicular homicide or cardiovascular event? The importance of the autopsy findings.

We present the case of a 61 years old woman who was hit by a car, resulting in fractures of the pubic bone, left ischium-pubis ramus and right femur, with need of hip replacement surgery. In the next days she was affected by two episodes of acute coronary syndrome, treated with coronary angioplasty surgery. After undergoing total hip replacement surgery an episode of asystole caused her death. A full autopsy showed coronary stenosis and chronic ischemic heart disease associated with a recent myocardial infarction. The pre-existing condition of T.L. could not be ignored but the initial traumatic event and the subsequent fractures played a further co-occurrent causal role. The initial trauma represented the first step of the phenomenological chain that led to a series of adverse cardiological events and to an irreversible asystole, so that the car driver should be partly considered accountable for the death of the woman.

The forensic value of the gastric content in head trauma injuries: A case report.

We present the case of a 69 years old man who was hit by a car while crossing the road. A CT scan of the skull and brain showed fracture of the left occipital bone, bilateral hemispheric subarachnoid hemorrhage, right frontal-temporal-parietal subdural hematoma with a shift of midline structures of 18 mm and complete obliteration of the third ventricle. He showed signs of anisocoria, absence of mobility of all 4 limbs and was immediately intubated and admitted to intensive care. The neurosurgeon was immediately consulted. He underwent drainage of subdural hematoma and two decompressive craniotomies, but died 15 days after the initial trauma. At autopsy, the stomach was full of a greenish poltaceous material. This gave us vital information in reconducting the actual brain death of the man to the immediacy of the investment, helping in the process of ruling out any possible profiles of professional liability.

Child Abuse: Adherence of Clinical Management to Guidelines for Diagnosis of Physical Maltreatment and Neglect in Emergency Settings.

Child maltreatment is a phenomenon of great importance due to the significant socio-health implications related to it. Purpose of the study is assessing compliance child abuse clinical management with guidelines and suggest corrective actions to avoid false negative or false positive judgments. The data come from 34 medical records of child victims of suspected abuse hospitalized in a pediatric clinic. We examined diagnostic and medico-legal management through the analysis of pediatric, dermatological, ophthalmological (including fundus examination), and gynecological (only in some cases) consultations, brain and skeletal imaging, laboratory tests (with reference to the study of hemostasis), and medico-legal advice. Of 34 patients, the average age was 23 months, ranging from 1 month to 8 years. The judgment was positive for abuse for 20 patients and negative for 12 patients; in two cases it was not possible to express a conclusive judgment. Two children died because of the injuries sustained. We underline the need of clinical-diagnostic standardized protocols, coroner in emergency settings, short-distance follow-up, social worker support. We also suggest objectifying in a descriptive way (using a common and repeatable language) and with photographic documentation the results of all the investigations carried out, to evaluate signs of physical maltreatment and neglect.

A COVID Dilemma: How to Manage Pregnancies in Case of Severe Respiratory Failure?

To date, the impact of the COVID-19 pandemic on the world's health, economics and politics is still heavy, and efforts to mitigate virus transmission have caused remarkable disruption. From the early onset of the pandemic, generated by SARS-CoV-2 spread, the scientific community was aware of its impact on vulnerable individuals, including pregnant women. The purpose of this paper is to highlight scientific pitfalls and ethical dilemmas emerging from management of severe respiratory distress in pregnant women in order to add evidence to this topic through an ethical debate. In the here-presented paper, three cases of severe respiratory syndrome are analyzed. No specific therapeutic protocol was available to guide physicians in a cost-benefit balance, and unequivocal conduct was not a priori suggested from scientific evidence. However, vaccines' advent, viral variants lurking on the horizon and other possible pandemic challenges make it necessary to maximize the experience gained through these difficult years. Antenatal management of pregnancies complicated by COVID-19 infection with severe respiratory failure is still heterogeneous and ethical concerns must be pointed out.

Medico-Legal Issues in Cremation: Comparative Analysis of International Legislation.

Cremation has seen a constant increase in popularity all around the world. Because of its extensively destructive nature, however, a series of medico-legal issues arise concerning identification, forensic autopsy, external examination, histological, toxicological and genetic exams to be performed not in the immediacy of death. The aim of this study is to compare the international legislation on cremation, seeking the response of various countries to their medico-legal issues. Several affinities but also some differences were found. Similarities include the need for a certificate by a medical examiner excluding any medico-legal issues and non-natural causes of death and the expression of consent to cremation given by the deceased when still alive otherwise by relatives. Significant differences were found in German law, which provides for a second medical examination prior to cremation and in Italian law providing for the medical examiner to collect biological samples from the body and store them for a minimum of ten years for any future purpose of justice. The Italian approach could give a plausible solution to the medico-legal issues raised by cremation with the imperative premise, however, we need to look deeply into its privacy and consent implications, cost-benefits rate, sample collection and storage protocol.

Suicide by Pesticide (Phorate) Ingestion: Case Report and Review of Literature.

It has been estimated that approximately one in seven of all global suicides is due to pesticide self-poisoning, mostly in rural areas of developing countries. Organophosphorus (OP) compounds are a group of pesticides exerting their toxicological effects through non-reversible inhibition of the enzyme acetylcholinesterase (AChE). Among these compounds, phorate (thimet) is one of the most dangerous compounds, the use of which is restricted in many countries. A case of intentional suicide after phorate ingestion in a 24-year-old Bengali male is described. This is the second case of suicidal ingestion of phorate reported in the forensic literature, and the first presenting complete toxicological findings.

Autoptic findings of sudden cardiac death (SCD) in patients with arrhythmogenic ventricular cardiomiopathy (AVC) from left ventricle and biventricular involvement.

OBJECTIVES: To evaluate autoptic histopathological findings of arrhythmogenic ventricular cardiomyopathy (AVC) as major cause of sudden cardiac death (SCD) in young adults. BACKGROUND: According to Heart Rhythm Society (HRS)'s international consensus, histological criteria for AVC diagnosis include a progressive myocardial atrophy of the right ventricle characterized by a transmural fatty or fibrofatty replacement in a segmental or diffuse pattern (residual myocytes <60 % vs 60-75 % by morphometric analysis) explaining the electrical instability with increased risk of SCD. However, there is increasing evidence for atypical patterns of localizations and percentage of fibrofatty replacement suggesting the need to update histopathological features of AVC. METHODS: Histology examination of ventricles, atria, and septum was performed on 10 autopsy of SCD due to AVC. Staining with hematoxylin-eosin and PicroSirius Red/Fast Green were performed on the heart samples to identify specific fibrofatty patterns. RESULTS: Our analysis showed that: 1) myocardial replacement by a diffuse segmental fatty or fibro-fatty tissue characterized right and left ventricles as well as atrial walls; 2) the degree of fibrofatty tissue replacement was less than 40 % both in left ventricle (n = 4, 40 %) and biventricular (n = 6, 60 %) localization; 3) perivascular fibrosis, inflammatory infiltrate, areas of hypertrophy and/or areas of coagulative necrosis as signs of hypoxic damage in the first stage. CONCLUSIONS: We confirmed prior evidence for fibrofatty replacement both in biventricular and septal localizations. Importantly, we observed a less degree (<40 %) of fibrofatty replacement as compared to current guidelines. This supports the need to further explore the histological patterns of fibrofatty infiltration in a larger study population to improve the histological diagnostic criteria of AVC.

Preservation of neurons in an AD 79 vitrified human brain.

Detecting the ultrastructure of brain tissue in human archaeological remains is a rare event that can offer unique insights into the structure of the ancient central nervous system (CNS). Yet ancient brains reported in the literature show only poor preservation of neuronal structures. Using scanning electron microscopy (SEM) and advanced image processing tools, we describe the direct visualization of neuronal tissue in vitrified brain and spinal cord remains which we discovered in a male victim of the AD 79 eruption in Herculaneum. We show exceptionally well preserved ancient neurons from different regions of the human CNS at unprecedented resolution. This tissue typically consists of organic matter, as detected using energy-dispersive X-ray spectroscopy. By means of a self-developed neural image processing network, we also show specific details of the neuronal nanomorphology, like the typical myelin periodicity evidenced in the brain axons. The perfect state of preservation of these structures is due to the unique process of vitrification which occurred at Herculaneum. The discovery of proteins whose genes are expressed in the different region of the human adult brain further agree with the neuronal origin of the unusual archaeological find. The conversion of human tissue into glass is the result of sudden exposure to scorching volcanic ash and the concomitant rapid drop in temperature. The eruptive-induced process of natural vitrification, locking the cellular structure of the CNS, allowed us to study possibly the best known example in archaeology of extraordinarily well-preserved human neuronal tissue from the brain and spinal cord.

Can COVID 2019 induce a specific cardiovascular damage or it exacerbates pre-existing cardiovascular diseases?

A novel coronavirus SARS-CoV-2 causes acute respiratory distress syndrome (ARDS) with cardiovascular and multiple organ failure till death. The main mechanisms of virus internalization and interaction with the host are down-regulation or upregulation of the ACE2 receptor, the surface glycoprotein competition mechanism for the binding of porphyrin to iron in heme formation as well as interference with the immune system. The interference on renin-angiotensin-aldosterone system (RAAS) activation, heme formation, and the immune response is responsible for infection diffusion, endothelial dysfunction, vasoconstriction, oxidative damage and releasing of inflammatory mediators. The main pathological findings are bilateral interstitial pneumonia with diffuse alveolar damage (DAD). Because ACE receptor is also present in the endothelium of other districts as well as in different cell types, and as porphyrins are transporters in the blood and other biological liquids of iron forming heme, which is important in the assembly of the hemoglobin, myoglobin and the cytochromes, multiorgan damage occurs both primitive and secondary to lung damage. More relevantly, myocarditis, acute myocardial infarction, thromboembolism, and disseminated intravasal coagulation (DIC) are described as complications in patients with poor outcome. Here, we investigated the role of SARSCoV-2 on the cardiovascular system and in patients with cardiovascular comorbidities, and possible drug interference on the heart.

The dating of thrombus organization in cases of pulmonary embolism: an autopsy study.

BACKGROUND: Pulmonary embolism (PE) is associated to high mortality rate worldwide. However, the diagnosis of PE often results inaccurate. Many cases of PE are incorrectly diagnosed or missed and they are often associated to sudden unexpected death (SUD). In forensic practice, it is important to establish the time of thrombus formation in order to determine the precise moment of death. The autopsy remains the gold standard method for the identification of death cause allowing the determination of discrepancies between clinical and autopsy diagnoses. The aim of our study was to verify the morphological and histological criteria of fatal cases of PE and evaluate the dating of thrombus formation considering 5 ranges of time. METHODS: Pulmonary vessels sections were collected from January 2010 to December 2017. Sections of thrombus sampling were stained with hematoxylin and eosin. The content of infiltrated cells, fibroblasts and collagen fibers were scored using a semi-quantitative three-point scale of range values. RESULTS: The 30 autopsies included 19 males (63.3%) and 11 females (36.7%) with an average age of 64.5 ± 12.3 years. The time intervals were as follows: early (≤1 h), recent (> 1 h to 24 h), recent-medium (> 24 h to 48 h), medium (> 48 h to 72 h) and old (> 72 h). In the first hour, we histologically observed the presence of platelet aggregation by immunofluorescence method for factor VIII and fibrinogen. The presence of lymphocytes has been identified from recent thrombus (> 1 h to 24 h) and the fibroblast cells were peripherally located in vascular tissue between 48 and 72 h, whereas they resulted central and copious after 72 h. CONCLUSIONS: After a macroscopic observation and a good sampling traditional histology, it is important to identify the time of thrombus formation. We identified histologically a range of time in the physiopathology of the thrombus (early, recent, recent-medium, medium, old), allowing to determine the dating of thrombus formation and the exact time of death. CLINICAL TRIAL NUMBER: NCT03887819. TRIAL REGISTRATION: The trial registry is Cliniclatrials.gov, with the unique identifying number NCT03887819. The date of registration was 03/23/2019 and it was "Retrospectively registered".

Parameters for estimating the time of death at perinatal autopsy of stillborn fetuses: a systematic review.

BACKGROUND: Stillbirth is defined by the WHO as birth of a fetus with no vital signs, at or over 28 weeks of pregnancy age. The estimation of time of death in stillbirth appears crucial in forensic pathology. However, there are no validated methods for this purpose. OBJECTIVE: To perform a systematic review of the available literature regarding the estimation of the time of death in stillborn fetuses, in terms of hours or days. METHODS: Electronic databases were searched from their inception to August 2018 for relevant articles. Macroscopic, histologic, and radiologic parameters were evaluated. RESULTS: Nine studies with 664 stillborns were included. The evaluation of extent and location of fetal maceration signs showed good accuracy in estimating the time of death; by contrast, a dichotomous assessment of maceration (present vs absent) was found to be unreliable in a subsequent study. Histologic assessment of the loss of nuclear basophilia in fetal and placental tissues showed excellent accuracy; an "autolysis equation" was proposed to achieve an even higher accuracy in fetuses who had been dead for < 24 h. Magnetic resonance imaging of the lung parenchyma, pleural fluids, and brain parenchyma could estimate the death-to-autopsy time, but the results appeared weak and conflicting. CONCLUSION: Pathologic examination, based on the assessment of maceration, and even more of the loss of nuclear basophilia, may be a reliable method to estimate the time of death in stillborn fetuses. Further studies should be encouraged to validate these results. Imaging techniques have not yet found application in this field.

To kill or be killed: the coup de grâce for a warrior after multiple sword wounds.

Finding traumatic lesions on ancient skeletal remains offers a unique opportunity to investigate the circumstances surrounding the time of death. Here we present the unique find of a late 17th, early 18th century young male from Southern Italy with eight traumatic skull lesions. A detailed anthropological examination using X-ray and 3D CT scanning techniques was conducted in order to evaluate traumatic extent, direction and degree of severity of each skull injury. The nature, number and timing of repair of the traumata suggest that they were intentional blows inflicted in battle. Gross and radiographic evidence shows that the individual survived long after one of these traumata, most likely suffered in a previous battle. Shape, size and location, as well as different orientation and implied trajectory of the multiple wounds, suggest that they were produced by a heavy, sharp cutting weapon. The perimortem aspect of most of the traumata revealed them to be contemporary injuries, suffered in a final assault by a heavy sword during a face-to-face combat. The largest and deepest fracture penetrating the skull cavity possibly resulting in traumatic brain injury was here suggested as the fatal one, even if the victim may have survived for several days prior to death.

A hypothesis of sudden body fluid vaporization in the 79 AD victims of Vesuvius.

In AD 79 the town of Herculaneum was suddenly hit and overwhelmed by volcanic ash-avalanches that killed all its remaining residents, as also occurred in Pompeii and other settlements as far as 20 kilometers from Vesuvius. New investigations on the victims' skeletons unearthed from the ash deposit filling 12 waterfront chambers have now revealed widespread preservation of atypical red and black mineral residues encrusting the bones, which also impregnate the ash filling the intracranial cavity and the ash-bed encasing the skeletons. Here we show the unique detection of large amounts of iron and iron oxides from such residues, as revealed by inductively coupled plasma mass spectrometry and Raman microspectroscopy, thought to be the final products of heme iron upon thermal decomposition. The extraordinarily rare preservation of significant putative evidence of hemoprotein thermal degradation from the eruption victims strongly suggests the rapid vaporization of body fluids and soft tissues of people at death due to exposure to extreme heat.

Ethical and Legal Issues in Gestational Surrogacy.

This study originated from events that occurred in 2014 in an Italian hospital, where the embryos of a couple, obtained by means of homologous insemination, were mistakenly implanted into the uterus of another woman who, along with her husband, underwent the same treatment. Faced with this serious adverse circumstance, that gives rise to ethical and legal issues, the authors conducted a comparative examination of how to consider the division of maternity (between biological mother and uterine mother) and the related division of paternity (between genetic father and legal father, husband or partner of the gestational mother). Some preliminary observations are made concerning parenthood and filiation within the context of currently applicable Italian law. The following is a detailed analysis of the arguments in favour of the parental figures involved (gestational mother/genetic mother).

The Central Importance of Information in Cosmetic Surgery and Treatments.

The increase in the number of people who choose to have medical procedures done to improve their appearance may be due to changed social and cultural factors in modern society, as well to the ease of access and affordable costs of these cosmetic treatments. Today, two elements legitimate recourse to this type of treatment: the broad definition of health accepted by the law and the scientific community, and the provision of meticulous information to the entitled party previous to obtaining his or her consent. In Italy, while current case-law views treatments exclusively for cosmetic purposes as unnecessary, if not even superfluous, it nonetheless demands that providers inform clients about the actual improvement that can be expected, as well as the risks of worsening their current esthetic conditions.

Aesthetic Dental Procedures: Legal and Medico-legal Implications.

Dental treatments, as well as simple anatomical and functional repair work, can also be for aesthetic purposes. This is because the anatomical area concerned, i.e. the oral cavity, has a great power of attraction. Aesthetic treatments in general - in particular dental treatments - have been on the rise in recent years, and this has also meant an increase in claims due to patient dissatisfaction with the results obtained. Numerous laws have been introduced that emphasise the need for comprehensive prior information in order to acquire valid consent. This has resulted in the elimination of the distinction between the obligation of means and obligation of result, with achievement of the normally expected result required in any case.
