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. The questionnaire had sections focusing on the professional background of respondents, annual assessment numbers, requesting parties and reasons, types of examinations conducted (e.g., physical, radiological), followed protocols, age estimation methods, and questions on how age estimates are reported.The questionnaire's findings reveal extensive engagement of the forensic community in age assessment in the living, emphasizing multidisciplinary approaches. However, there seems to be an incomplete appreciation of AGFAD guidelines. Commonalities exist in examination methodologies and imaging tests. However, discrepancies emerged among respondents regarding sexual maturity assessment and reporting assessment results. Given the increasing importance of age assessment, especially for migrant child protection, the study stresses the need for a unified protocol across European countries. This can only be achieved if EU Member States wholeheartedly embrace the fundamental principles outlined in EU Directives and conduct medical age assessments aligned with recognized standards such as the AGFAD guidelines.

Atypical Postmortem "Incaprettamento" After an Honor Homicide.

ABSTRACT: Honor killing is a murder carried out to protect the family's reputation by actions that are perceived as shameful. Usually, honor killing occurs to preserve family's honor, which has been violated by adulteries, premarital pregnancies, or inappropriate relationships. In Southern Italy, the culture of honor is quite strong especially among the local criminal organizations. Honor crimes by Italian Mafia are intended to have an admonitory significance, and they can be carried out following a macabre ritual of "incaprettamento." The aim is to humiliate the victim treating him like an animal, a bonded young goat where the victim is secured by a rope passing behind the back from the upper to lower extremities. In this case study, the honor homicide was perpetrated against the lover of a butcher's wife by sharp weapon, followed by a postmortem atypical incaprettamento of the corpse. The wrists and ankles were tied together by ropes, and the extremities were fixed to the abdomen with a string. The body was also wrapped in a plastic tape after penile amputation. According to killer's confession, the mutilation and the incaprettamento were expressions of revenge and contempt for the victim to restore the honor lost.

Suicide by ligature strangulation and/or hanging inside a motor vehicle: a comprehensive review.

Suicide by ligature strangulation/hanging inside vehicles is uncommon, and only few cases have been reported in the literature. This study aimed to conduct a comprehensive review of reported cases of suicide by ligature strangulation/hanging inside vehicles, analyzing the features of the death scene, of the ligature and furrow, autopsy findings, and causes of death. The comprehensive review was performed following the PRISMA guidelines by using the most common scientific databases. According to inclusion criteria, a total of 20 cases of vehicle-assisted strangulation/hanging were reviewed: 13 cases were assessed as ligature strangulation resulting in 7 complete decapitations and 7 other cases as hanging. All victims were young or adult males, except for one 48-year-old female. Death was assessed as suicide in all cases, except for a possible accidental autoerotic death. In 8 cases, a history of depression or other psychiatric disorders was reported. Toxicological analysis were positive in 7 cases. Hard ligature materials (nylon, steel, plastic, hemp ropes) were used in most cases, but only 13 cases had a well-demarcated furrow. In 2 cases, no internal findings of asphyxia were found. An additional case of ligature strangulation inside a motor vehicle off is also presented, where no autopsy findings of asphyxia were observed, except for a broad pale furrow and monolateral conjunctival petechiae. This study highlights the challenges in classifying suicidal hanging and ligature strangulation in motor vehicles.

COVID-19: detection methods in post-mortem samples.

COVID-19 identification is routinely performed on fresh samples, such as nasopharyngeal and oropharyngeal swabs, even if, the detection of the virus in formalin-fixed paraffin-embedded (FFPE) autopsy tissues could help to underlie mechanisms of the pathogenesis that are not well understood.The gold standard for COVID-19 detection in FFPE samples remains the qRT-PCR as in swab samples, contextually other methods have been developed, including immunohistochemistry (IHC), and in situ hybridization (ISH). In this manuscript, we summarize the main data regarding the methods of COVID-19 detection in pulmonary and extra-pulmonary post-mortem samples, and especially the sensitivity and specificity of these assays will be discussed.

PD-L1 Overexpression in the Lungs of Subjects Who Died from COVID-19: Are We on the Way to Understanding the Immune System Exhaustion Induced by SARS-CoV-2?

Knowledge of the pathogenic mechanisms of severe acute respiratory syndrome-associated coronavirus 2 (SARS-CoV-2) is certainly a priority for the scientific community. Two main elements are involved in the biology of the most severe forms of coronavirus disease 2019 (COVID-19): the direct cytopathic effect of the virus against the host tissues, and a dysfunction of the immune system, characterized by the exhaustion of T lymphocytes. The exhaustion of T cells in COVID-19 is poorly understand, but some data could suggest a possible role of PD-1/PD-L1 axis. The aim of this study was to evaluate the possible role of PD-L1 expression in the pulmonary tissue in subjects affected by COVID-19. The presence of SARS-CoV-2 in the pulmonary tissue, and its exact location, was indagated by in situ hybridization; the expression of PD-L1 and CD8 in the same tissue was indagated by immunohistochemistry. Overall, PD-L1 resulted diffusely expressed in 70% of the cases, and an intense expression was observed in 43.5% of cases. Diffuse and intense presence of SARS-CoV-2 by in situ hybridization significantly correlated with an intense PD-L1 expression, and with expression of PD-L1 by pneumocytes. PD-L1 is overexpressed in the pulmonary tissue of subjects died from COVID-19, and mainly in subjects with a high viral load. These data suggest a possible role of PD-L1 in the immune system exhaustion at the basis of the severe forms of the disease.

Postmortem interval assessment by MALDI-TOF mass spectrometry analysis in murine cadavers.

AIMS: This study assessed the use of matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry as an alternative method to identify species associated with the thanatomicrobiota and epinecrotic communities. METHODS AND RESULTS: The study was conducted on 10 murine cadavers, and microbiological swabs were collected from five external anatomical sites (eyes, ears, nose, mouth and rectum) and four internal organs (brain, spleen, liver, heart), during 16 and 30 days, for the thanatomicrobiota and epinecrotic communities, respectively. Our results revealed that the postmortem microbiota associated with the external cavities showed changes over time and reduced taxonomic diversity. The internal organs, initially sterile, showed signs of microbial invasion at 3 and 10 days postmortem for the liver-spleen and heart-brain, respectively. The postmortem microbiota was mainly dominated by Firmicutes and Proteobacteria. CONCLUSIONS: MALDI-TOF is a promising method for estimating postmortem interval (PMI), associated with rapid sample handling, good reproducibility and high productivity. SIGNIFICANCE AND IMPACT OF THE STUDY: This study investigated microbial changes during the decomposition process and proposed a simple strategy for PMI estimation. Results introducing the application of the MALDI-TOF method in the field of forensic.

Glycated ACE2 receptor in diabetes: open door for SARS-COV-2 entry in cardiomyocyte.

RATIONALE: About 50% of hospitalized coronavirus disease 2019 (COVID-19) patients with diabetes mellitus (DM) developed myocardial damage. The mechanisms of direct SARS-CoV-2 cardiomyocyte infection include viral invasion via ACE2-Spike glycoprotein-binding. In DM patients, the impact of glycation of ACE2 on cardiomyocyte invasion by SARS-CoV-2 can be of high importance. OBJECTIVE: To evaluate the presence of SARS-CoV-2 in cardiomyocytes from heart autopsy of DM cases compared to Non-DM; to investigate the role of DM in SARS-COV-2 entry in cardiomyocytes. METHODS AND RESULTS: We evaluated consecutive autopsy cases, deceased for COVID-19, from Italy between Apr 30, 2020 and Jan 18, 2021. We evaluated SARS-CoV-2 in cardiomyocytes, expression of ACE2 (total and glycosylated form), and transmembrane protease serine protease-2 (TMPRSS2) protein. In order to study the role of diabetes on cardiomyocyte alterations, independently of COVID-19, we investigated ACE2, glycosylated ACE2, and TMPRSS2 proteins in cardiomyocytes from DM and Non-DM explanted-hearts. Finally, to investigate the effects of DM on ACE2 protein modification, an in vitro glycation study of recombinant human ACE2 (hACE2) was performed to evaluate the effects on binding to SARS-CoV-2 Spike protein. The authors included cardiac tissue from 97 autopsies. DM was diagnosed in 37 patients (38%). Fourth-seven out of 97 autopsies (48%) had SARS-CoV-2 RNA in cardiomyocytes. Thirty out of 37 DM autopsy cases (81%) and 17 out of 60 Non-DM autopsy cases (28%) had SARS-CoV-2 RNA in cardiomyocytes. Total ACE2, glycosylated ACE2, and TMPRSS2 protein expressions were higher in cardiomyocytes from autopsied and explanted hearts of DM than Non-DM. In vitro exposure of monomeric hACE2 to 120 mM glucose for 12 days led to non-enzymatic glycation of four lysine residues in the neck domain affecting the protein oligomerization. CONCLUSIONS: The upregulation of ACE2 expression (total and glycosylated forms) in DM cardiomyocytes, along with non-enzymatic glycation, could increase the susceptibility to COVID-19 infection in DM patients by favouring the cellular entry of SARS-CoV2.

Isolated Right Atrial Rupture From Blunt Chest Trauma in Motor Vehicle Collisions: Mechanisms of Injury and Outcomes.

ABSTRACT: Isolated right atrial rupture after nonpenetrating blunt chest trauma is rare, and very few cases have been reported in the literature. Isolated right atrial rupture is a diagnostic challenge in these patients, who are mostly victims of motor vehicle collisions. The clinical presentation is heterogeneous and can vary depending on rupture location and size. The anatomical sites mostly involved are the appendage and the free wall followed by the superior and inferior vena cava junctions. The present case study shows a fatal isolated rupture of the right atrial appendage in a victim of a motor vehicle collision. At the emergency room, a computed tomography scan revealed a severe pericardial blood effusion, and pericardiocentesis was promptly performed. Unfortunately, the patient suddenly worsened just before cardiac surgery. Autopsy findings showed a cardiac tamponade due to a linear laceration 1.8 cm in length on the right atrial appendage. No other relevant injuries were observed. A prompt diagnosis of isolated right atrial rupture can be crucial for victims of blunt chest trauma with unexplained hypotension or hemodynamic instability to improve their chances of survival. Medicolegal issues can be raised mainly related to delayed diagnosis. Once a cardiac rupture is suspected, the injury repair is essential to achieve the best outcome.

Fatal poisoning by ingestion of a self-prepared oleander leaf infusion.

An unusual case of poisoning by the ingestion of oleander leaves is reported. A 71 year old male laboratory technician committed suicide at home in this unusual manner. At the death scene a steel pan and other paraphernalia, used for the extraction of oleandrin and other cardiac glycosides from the leaves of the Nerium oleander plant were found.Toxicological investigations for oleandrin, oleandrigenin, neritaloside, and odoroside were performed by LC-MS/MS on all biological samples (peripheral blood, vitreous humor, urine, liver, gastric contents) and on the yellow infusion found at the death scene.In all samples, toxic levels of oleandrin were detected (blood 37.5 ng/mL, vitreous humor 12.6 ng/mL, urine 83.8 ng/mL, liver 205 ng/mg, gastric content 31.2 µg/mL, infusion 38.5 µg/mL). Qualitative results for oleandrigenin, neritaloside, and odoroside were obtained. Oleandrigenin was present in all tissue samples whereas neritaloside and odoroside were absent in the blood and vitreous humor but present in urine, liver, gastric content, and in the leaf brew.The purpose of this study was the identification of oleandrin and its congener oleandrigenin, detected in the vitreous humor. The blood/vitreous humor ratio was also calculated in order to assess of the likely time interval from ingestion to death. According to the toxicological results death was attributed to fatal arrhythmia due to oleander intoxication. The manner of death was classified as suicide through the ingestion of the infusion.

Sex estimation of skeletons in middle and late adulthood: reliability of pelvic morphological traits and long bone metrics on an Italian skeletal collection.

There are several metric and morphological methods available for sex estimation of skeletal remains, but their reliability and applicability depend on the sexual dimorphism of the remains as well as on the availability of preserved bones. Some studies showed that age-related changes on bones can cause misclassification of sex. The purpose of this study was to establish the reliability of pelvic morphological traits and metric methods of sex estimation on relatively old individuals from a modern Italian skeletal collection. The data for this study were obtained from 164 individuals of the Milano CAL skeletal collection and average age of the samples was 75 years. In the pelvic morphological method, the recalibrated regression formula of Klales and colleagues (2012), pre-auricular sulcus, and greater sciatic notch morphology were used for sex estimation. With regard to the metric method, 15 standard measurements from upper and lower limbs were analyzed for sexual dimorphism. The results showed that in pelvic morphological approach, the application of regression formula of the revised Klales and colleague formula (2017) resulted in 100% accuracy. Classification rates of metric methods vary from 75.19 to 90.73% with the maximum epiphyseal breadth of proximal tibia representing the most discriminant parameter. This study confirms that the effect of age on sex estimation methods is not substantial, and both metric and morphological methods of sex estimation can be reliably applied to individuals of Italian descent in middle and late adulthood.

Postmortem Otorrhagia in Positional Asphyxia.

Otorrhagia is generally associated with basilar skull fractures or diving accidents. In routine forensic medical practice, an accurate knowledge of the etiology of otorrhagia may have a key role to distinguish between traumatic and atraumatic causes and accidental, homicidal, or suicidal manners. The authors present the case of an unusual cause of atraumatic otorrhagia occurred in an elderly farmer found dead in a barn. He remained entrapped in a narrow tunnel created by some hay bales. The autopsy findings revealed only an intense polyvisceral congestion and subpleural petechiae, with no signs of traumatic injuries and no fractures of skull base or temporal pyramid. The cause of death was determined to be positional asphyxia, and the manner of death was deemed accidental. In fact, the head-down position resulted in diaphragm compression causing respiratory failure in combination with the stasis of the upper venous circle districts. Mechanical and gravitational forces related to upside-down position and increased vascular pressure also caused postmortem otorrhagia. In this case, the death scene investigation and circumstantial information allowed for reconstruction of the unique dynamics of the death. At the death scene, the position of the corpse must be accurately investigated because it can explain some cadaveric findings such as the ear bleeding or other markers of increased cephalic venous pressure like pink teeth, facial and conjunctival petechiae, or Tardieu spots. Therefore, forensic pathologists should consider that ear bleeding in dead bodies is not always the evidence of severe head blunt trauma or diving accidents, but it might be a postmortem phenomenon mostly related to body position.

The synergy between radiographic and macroscopic observation of skeletal lesions on dry bone.

The diagnosis of bone lesions is a fundamental part of the study of skeletal remains, both in the archeological and forensic context. On the one side, the literature proved the relevance of radiography for the detection of bone lesions; on the other side, the careful macroscopic observation of the morphology of bone lesions is often underestimated. For this study, we examined and performed plain radiography on 14 skeletons of the CAL Milano Cemetery Skeletal Collection diagnosed with rheumatoid arthritis, diabetes, multiple myeloma, metastatic cancer, and osteomalacia to compare the macroscopic morphology and radiographic visualization of bone lesions. At least 200 osteolytic lesions and 65 areas of proliferative bone reaction (either spongiosclerotic or periosteal) were studied. We realized "comparative sets" of macroscopic pictures and radiographic imaging of the same skeletal elements to allow comparisons of detection and recognition of bone lesions. As a result, while trabecular lesions may be lost through naked eye observation, many lesions can also be unperceived on radiographs due to contrast, including periosteal reactions, osteolytic lesions, and spongiosclerosis. The aim of this research was to investigate the strengths and pitfalls of digital radiography and macroscopic analysis and to demonstrate the synergy of a complementary approach between the two methods for lesion analysis in dry bone.

The potential impact of multidimesional geriatric assessment in the social security system.

AIM: To evaluate the efficacy of multidimensional geriatric assessment (MGA/CGA) in patients over 65 years old in predicting the release of the accompaniment allowance (AA) indemnity by a Local Medico-Legal Committee (MLC-NHS) and by the National Institute of Social Security Committee (MLC-INPS). METHODS: In a longitudinal observational study, 200 Italian elder citizens requesting AA were first evaluated by MLC-NHS and later by MLC-INPS. Only MLC-INPS performed a MGA/CGA (including SPMSQ, Barthel Index, GDS-SF, and CIRS). This report was written according to the STROBE guidelines. RESULTS: The data analysis was performed on January 2016. The evaluation by the MLC-NHS and by the MLC-INPS was in agreement in 66% of cases. In the 28%, the AA benefit was recognized by the MLC-NHS, but not by the MLC-INPS. By the multivariate analysis, the best predictors of the AA release, by the MLC-NHS, were represented by gender and the Barthel Index score. The presence of carcinoma, the Barthel Index score, and the SPMQ score were the best predictors for the AA release by MLC-INPS. CONCLUSIONS: MGA/CGA could be useful in saving financial resources reducing the risk of incorrect indemnity release. It can improve the accuracy of the impairment assessment in social security system.

Effects of different storage and measuring methods on larval length values for the blow flies (Diptera: Calliphoridae) Lucilia sericata and Calliphora vicina.

In forensic entomology, the methods of sampling, killing, and storing entomological samples can affect larval age estimation, and, hence, the estimation of the minimum post-mortem interval. In the existing manuals, there is a certain amount of heterogeneity regarding methods and the recommendations for best practice in forensic entomology are insufficiently validated. This study evaluated three different length-measurement methods for larval stages and examined the influence of different killing and storing methods on the larval length of two forensically important blow flies, Lucilia sericata and Calliphora vicina. The three different measuring methods were a) a ruler with a 0.1mm scale, b) a geometrical micrometer, and c) a computer-aided stereomicroscope. They were used to measure the length of L1-L3C. vicina larvae and detect no significant differences. This supports the view that a simple tool like a geometrical micrometer can produce reliable results in forensic entomology. Newly hatched larvae of L. sericata and C. vicina were killed with hot water (HW) and divided into two equal subsamples. Lengths of all larvae were measured immediately after killing, then every 24h until day 4, and once more after 7days of storage in ≥70%-ethanol. L. sericata larvae only showed significant changes in length in the HW group stored at room temperature. After 4 and 7days of storage, these 24-h- and 72-h-old larvae showed a significant decrease in length compared with those in a fridge at 6°C. This decrease can, however, be considered a negligible natural variation without forensically relevant consequences for larval age estimation of L. sericata samples. For C. vicina, an increase in length was observed over time. This was significant only for younger larvae (24-48h old) stored in 70%-ethanol. This variance in length can lead to a wrong estimation of age; however, only for larvae stored in 70%-ethanol, not for those stored in 96%-ethanol. NOVELTY STATEMENT: We examined the influence of different killing and storing methods on two forensically important blow flies, Lucilia sericata and Calliphora vicina. For the latter species we additionally were evaluating three different length measurement methods. The results of both experiments suggest that it is possible to kill and store fly larvae directly in (not hot) ≥70%-ethanol. This simplifies the sampling and storing of fly evidence at the crime scene. We also compared the influence of three different measuring methods for estimating the length of L1-L3 C. vicina larvae by using a) a ruler with a 0,1mm scaling, b) a geometrical micrometer and c) a computer-aided stereomicroscope. No significant differences were detected, supporting the view, that a simple tool like a geometrical micrometer can produce reliable results. This study helps to simplify the sampling and evaluation of entomological evidence and to backup or questioning existing guidelines and best practice recommendations.

Pathological alterations and COHb evaluations as tools for investigating fire-related deaths in veterinary forensic pathology.

Fire-related deaths are usually a consequence of carbon monoxide (CO) poisoning or shock from thermal injuries. In humans, high levels of carboxyhemoglobin (COHb) concentrations in the blood can support a diagnosis of CO poisoning. In veterinary medicine, few studies investigated the pathological changes and blood COHb% in fire victims, and no data are available on post-mortem changes in blood gas composition due to fire. This study aims to investigate the pathological changes and COHb levels in both animal victims of fire and cadavers experimentally exposed to fire. For this purpose, dogs were selected and subdivided into three groups. Group A comprised 9 adult dogs, and Group B comprised 7 puppies that died under fire-related conditions. Group C was represented by 4 dog cadavers experimentally exposed to heat and smoke. A complete macroscopic, histological, and COHb evaluation were performed on each animal. Animals in Groups A and B showed cherry-red discoloration, thermal-injuries and soot deposits along the respiratory tract. Animals in Group C showed thermal injuries and soot deposits limited to the upper respiratory tract. The mean COHb% values in cadavers in Group C were lower than those observed in the other groups but higher compared to the values detected before the heat and smoke treatment. These findings suggest that both pathological changes and COHb analysis are valid tools for investigating fire-related deaths in dogs. However, the increase of COHb levels in cadavers exposed post-mortem to heat and smoke highlights how the COHb analysis should always be evaluated together with macroscopical and microscopical findings to avoid significant misjudgments in investigating fire-related fatalities in veterinary forensic practice.

Migrant deaths and the Kater Radez I wreck: from recovery of the relict to marine taphonomic findings and identification of the victims.

On March 1997, during a naval blockade imposed by Italy to prevent illegal immigration, the motorboat Kater Radez I full of Albanian refugees clashed with an Italian warship with 120 people approximately on board. The boat sank quickly after the collision just in the middle of the Otranto Canal (Mediterranean Sea). Only 34 individuals survived the accident; 58 died, mostly women and children, and dozens were missing. After 7 months spent at depth of 800 m approximately underwater to constant temperature of 4 °C, the motorboat was rescued, and totally, 52 bodies were recovered from the holds. The management of the mass disaster is summarized focusing on the procedures applied in the recovery of the boat and victims, and the identification process. The purpose of the article is to present the unique taphonomic model of decomposition dealing with marine sequestered environments. The postmortem changes have been revised according with a skeletonization scoring system. Surprisingly, most of the victims were in good condition with soft tissues still present except at the head/neck region and the hands resulting in the body parts mostly pre-skeletonized. Closed compartments as well as heavy clothing in multiple layers protected the bodies from animal activity of marine scavengers. Presumptive positive identification was obtained in 49 out of 52 bodies based on the correspondence between ante- and postmortem data. An additional purpose of the article is also to focus on the practice of coercive actions disproportionate to the risk of unauthorized entry criticized by several international organizations for migration and recently condemned by the European Court in Strasbourg.

Colorectal Cancer: 35 Cases in Asbestos-Exposed Workers.

BACKGROUND: Asbestos is considered one of the major global work-related carcinogens. Some studies suggest a potential causal relationship between asbestos exposure and colorectal cancer (CRC). However, the role of asbestos in CRC carcinogenesis is still controversial. METHODS: 35 claims of occupational CRC among asbestos-exposed workers were reviewed. All claims were rejected by the Italian National Institute for Insurance against Accidents (INAIL) due to the "lack of scientific evidence in the causality" between asbestos exposure and CRC; causality was finally assessed in civil trials. All cases were categorized by age, gender, industry type, task, exposure and latency periods, anatomical location, and histopathological characteristics of CRC and concomitant respiratory diseases. RESULTS: Most workers were males aged 60 years or more and employed in occupational activities with extensive use of asbestos for over 20 years. In 31 out of 35 cases, CRC was diagnosed over 39 years after employment. Right-sided colic adenocarcinoma was diagnosed in nine cases; rectum was involved in eight cases. Respiratory comorbidities were observed in 22 workers. CONCLUSIONS: Our study provides some interesting points in the assessment of the causal relationship between asbestos exposure and CRC.

Choking in patients with neurological disorders and role of drug-induced dysphagia.

Choking is a type of asphyxia due to the internal obstruction of airways by foreign material, quite always food. Most choking deaths are accidental and occur so quickly that may mimic a heart attack. This scenario is also known as "Cafè coronary syndrome" or "bolus death". At autopsy, pieces of under-chewed food are commonly lodged at, above, or in the tracheal space adjacent to the laryngeal inlet. In these fatal events mechanisms other than asphyxia can be also involved, such as a vasovagal episode (by stimulation of the autonomic nerve plexus of the laryngeal inlet) or swallowing impairment. Swallowing is a complex, semi-automatic process that can be affected by various disorders (i.e. dementia, Parkinson, neurological injuries, etc.), senility and external factors causing oropharyngeal dysphagia (OD). Among these factors, several drugs have been also associated with impaired swallowing, including drugs acting on the CNS like antipsychotics and antiepileptics. Three cases of witnessed bolus deaths are reported. All victims were affected by neurological defects and took medications acting on CNS. In all cases, at autopsy pieces of food were found distributed from the laryngeal inlet along the main axis of the trachea up to the large bronchi over the bifurcation. Additional autopsy findings were represented by facial congestion and cyanosis, subepicardial petechiae and pulmonary emphysema.

Gunshot injuries in Campania (Italy): A retrospective thirty-years (1981-2011) study.

From 1981 to 2011, 200 firearm deaths were autopsied in Naples, at the Institute of Legal Medicine of the University of Campania "Luigi Vanvitelli". 188 cases were homicides and most of them (116) were related to the local organized crime. The majority of victims were young Italian males in the 20-39 age fired in outdoor environments. The reason for choosing outdoor environments can be related to the opportunity for the killer run from the crime scene immediately after the murder. Only 11 of the bodies autopsied were suicide victims, mostly older individuals, over 50 years -old with history of mental illness. All the suicides occurred in indoor environments in order to protect their domestic intimacy. Only two female victims were accounted in this historical series which is quite impressive if compared to recent phenomenon of feminicides occurring mostly in domestic environments. A total of 772 entry wounds were observed: 658 fired from single-charge handguns and 114 from multiple-charge firearms. 9x21 pistol cartridge was the most common ammo used, followed by the 7.65 Parabellum. The head was the most common anatomical site injured (in 81.8% of the suicides cases and in 68.6% of homicides). Most of the victims of homicide died before arriving at an Emergency Service. Only a minority of victims lived from few hours up to less than a week, after being shot, and very few victims remained alive up to a couple of months.

Accidental Injury or "Shaken Elderly Syndrome"? Insights from a Case Report.

Subdural haemorrhage (SDH) as result of a traumatic brain injury (TBI) is a common cause of death in cases of fatal physical abuse. Since intracranial bleeding is a common finding in elderly due to age-related intracranial changes or increasing prevalence of anticoagulant medication, differential diagnosis between inflicted and non-inflicted head injury is challenging. A case of an elderly woman's death caused by TBI is reported. Autopsy showed multiple polychromatic bruises and a frontoparietal hematoma with bilateral subacute SDH. History excluded paraphysiological or pathological non-traumatic conditions that could justify SDH, while iatrogenic factors only played a contributory role. Since polychromatic bruises distributed on the face, the upper extremities and the chest were consistent with forceful grasping/gripping or repeated blows and SDH can form in absence of impact or by mild/minor blows, SDH was considered the result of repeated physical abuses. Differential diagnosis between traumatic and non-traumatic SDH is still challenging for forensic pathologists. As largely accepted in the pediatric population and occasionally described also in adults, however, violent shaking should be also considered as a possible mechanism of SDH-especially in elderly who do not have any sign of impact to the head.
