Multiple nail gun injuries: suicide or homicide?

Nail gun injuries are a forensic problem; it can be difficult to distinguish self-inflicted injuries from accident and homicide instances. This kind of injuries shares some characteristics with both gunshot and puncture wounds. We describe a peculiar case of a man who committed suicide driving nails into his skull using a pneumatic nail gun. Entrance wounds were found on both temporal regions of the head. Reviewing scientific literature, this is the first case in Italy reporting the macroscopic data of bilateral head and brain nail gun injuries during an autopsy. Circumstantial elements were not sufficient to clarify if these lesions were self-inflicted, inflicted by accident, or else. Radiological examination can be helpful to show the exact location of the nails, but it has also its own limitations. We firmly believe that autopsy, especially the head section, is crucial to identify the nature and the extension of these lesions, thus giving us much more information about the mechanism of death and the circumstances in which it occurred.

Spectrophotometric evaluation of postmortem lividity: a proposal of a model for negroid ethnic race.

The interpretation of tanatochronological data is a fundamental aspect of the medico legal diagnosis, because it allows to trace back the interval of death. Traditionally, the evaluation of the hypostasis plays a relevant role in the interpretation of such information, despite its well-known limits and fallacies. In order to evaluate the degree of hypostatic area discoloration, the methodology currently used is highly subjective and influenced by several variables. The hypostasis pattern in individuals with V-VI phototype is useless because their post-mortem lividity is not estimable due to the color of the skin. This makes much harder to estimate the interval between the death and the detection of the tanatochronological data. This study is aimed at defining a highly accurate procedure to develop an objective method to estimate the hypostasis' degree of fixation with scientific accuracy on people with darker skin. The technology used is spectrophotometry Antera3D: this device is able to analyse the hypostasis by measuring the mean hemoglobin quantitative level in the skin either before and after a standardized compression, thus obtaining a numerical value that is directly related to the time of death. The method here presented allows analysing the hemoglobin amount in the skin of a dead body, without the influence of the melanin pigment in the definition of the hypostatic area color, therefore enabling us to overcome the objective limits of the direct and empiric estimation of the hypostasis decoloration. By creating a standardized method it's possible to reduce the operator-dependent error and to introduce a valid and applicable procedure in order to estimate the post-mortem interval.

Lethal event in diving with self-contained underwater breathing apparatus: A forensic study.

Introduction: In fatal accidents during scuba diving, it is necessary to differentiate a death from primary drowning from a secondary drowning death that is primarily due to other etiopathogenetic factors. The inhalation of water can only be the end point of a series of events capable of causing the diver's exitus. This study aims to demonstrate that even low-risk heart disease in daily life become potentially fatal during scuba diving. Methods: In this case series, we describe all cases of deaths in the course of diving that came to the observation of the Forensic Institute of the University Bari over 20 years (2000-2020). A judicial autopsy was performed on all subjects, with ancillary execution of histological and toxicological investigations. Results: The results of the medicolegal investigations carried out in the complex identified heart failure with acute myocardial infarction as the cause of death in four cases characterized by severe myocardiocoronarosclerosis, a primary drowning in a subject without previous pathological substrate in one case, and a terminal atrial fibrillation induced by acute dynamic heart failure due to functional overload of the right ventricle in one case. Conclusion: Our study demonstrates that lethal events during diving are often related to the presence of unrecognized or subclinical cardiovascular diseases. Such deaths could be prevented and avoided if a greater regulatory sensitivity to preventing and controlling diving was encouraged, considering both the inherent risks of this activity and the possible unrecognized or underestimated pathologies.

Necrotizing Fasciitis of the Thigh as Unusual Colonoscopic Polypectomy Complication: Review of the Literature with Case Presentation.

Necrotizing fasciitis (NF) is an infection characterized by necrosis of the superficial muscle fascia and surrounding soft tissues. It usually occurs following skin breaches from penetrating traumas or high-degree burns. Less frequently, it could be related to major abdominal surgery. However, no cases of thigh NF after minor abdominal procedures have ever been reported. A previously healthy 59-year-old male patient underwent a colonoscopic polypectomy. After the procedure, the patient developed an increasing right groin pain. The CT scan showed a gas collection in the right retroperitoneum space and in the right thigh soft tissues. Thus, a right colon perforation was hypothesized, and the patient was moved to the nearest surgery department and underwent a right hemicolectomy procedure. During surgery, the right thigh was also incised and drained, with gas and pus leakage. Nevertheless, the right lower limb continued to swell, and signs of systemic infection appeared. Afterward, clinical conditions continued to worsen despite the drainage of the thigh and antibiotic therapy, and the patient died of septic shock after just two days. This case shows that, although rare, lower limb NF should be considered among the causes of early post-operative local painful symptoms.

Post-mortem persistence of SARS-CoV-2: a preliminary study.

Since the beginning of March 2020, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been the cause of millions of deaths worldwide. The need to better define the pathogenesis of coronavirus disease 19 (Covid-19) as well as to provide the correct statistical records concerning deaths related to this virus, inevitably involves the role of forensic pathology and routine autopsy practice. Currently, some data on macroscopic and microscopic features in autopsies performed in suspected Covid-19 cases are reported in the literature. The persistence of SARS-CoV-2 in cadavers has not yet been elucidated and only a few reports have emphasized the importance of evaluating the Virus RNA in post-mortem tissues. In this preliminary study, we observed that SARS-CoV-2 survives in multiple cadaver tissues many days after death despite some extreme conditions of post-mortem body preservation. The results of this on-going analysis could help improve the safety of working practices for pathologists as well as understanding the possible interaction between microbiological agents and the cadaver tissue's supravital reactions.

A Comparison of 3 Established Skeletal Age Estimation Methods in an African Group From Benin and an Italian Group From Southern Italy.

Age estimation is a crucial matter in several forensic and legal instances. The literature recommends carrying out hand and wrist radiograph to assess skeletal age. Much research has been conducted to examine the application of various methods in different categories. Our study aims to evaluate the reliability of Greulich and Pyle, Tanner-Whitehouse 2, and FELS methods in Beninese and Italian samples, with a total of 204 subjects, 102 (51 were male and 51 were female) from Benin and 102 (51 were male and 51 were female) from Italy, aged between 4 and 19 years. Hand-wrist radiographs were carried out at Saint Luc Hospital in Cotonou for the African sample and in 2 hospitals in Southern Italy for Italian sample. Skeletal maturity was obtained, applying the 3 methodologies. The arithmetic mean of the 3 ages obtained was calculated, as well as the possible difference between the known chronological age and the estimated mean skeletal age. Data were analyzed statistically using the χ test, Student t test, and Bland-Altman plots. There are no significant statistical differences between real age and skeletal age calculated using the Greulich and Pyle and FELS methods. Comparison between Tanner-Whitehouse 2 and the average of the methods used results in statistically significant, but clinically insignificant, differences.

Her life ended jumping from the fifth floor: the importance of scene investigation and the need for restrictive means to prevent jumping suicide.

In January 2014, a dead woman was found lying near the back entrance of a building belonging to Bari University Hospital compound. After the external examination and identification of the corpse, through history, circumstances, and postmortem findings, it was supposed that the woman probably committed suicide, by jumping from the nearby building. But only after additional investigation of the scene was it possible to locate the window through which the victim had jumped, by assessing the height from which she leapt. We underline the importance of the examination of the scene. It has to be done with circumspection, even in cases that could be considered routine, paying attention to details, not excluding things that, at first glance, seem to be unnecessary. Inspection needs time, patience and accuracy, knowledge, competence, and intuition and must be the result of an efficient team action. Furthermore the occurrence of suicides, particularly jumping from a height, among immediate postdischarge psychiatric patients, stresses the importance of immediate follow-up treatment and alternative preventive strategies, considering, of course, the feasibility of structural means.

Validation and application of a method for the quantification of 137 drugs of abuse and new psychoactive substances in hair.

INTRODUCTION: In the dynamic universe of new psychoactive substances (NPS), the identification of multiple and chemically diverse compounds remains a challenge for forensic laboratories. Since hair analysis represents a gold-standard to assess the prevalence of NPS, which are commonly detected together with classical drugs of abuse (DoA), our study aimed at developing a wide-screen method to detect and quantify 127 NPS and 15 DoA on hair. MATERIALS AND METHODS: A multi-analyte ultra-high performance liquid chromatography mass spectrometry method for the identification and quantification of 127 NPS (phenethylamines, arylcyclohexylamines, synthetic opioids, tryptamines, synthetic cannabinoids, synthetic cathinones, designer benzodiazepines) and 15 DoA in hair samples was developed. A full validation was performed according to the European medicines Agency (EMA) guidelines, by assessing selectivity, linearity, accuracy, precision, limit of quantification (LOQ), limit of detection (LOD), matrix effect and recovery. As a proof of the applicability, the method was applied to 22 authentic hair samples collected for forensic purposes. RESULTS: Successful validation was achieved, by meeting the required technical parameters, for 137 compounds (122 NPS and 15 DoA), with LOQ set at 4 pg/mg for 129 compounds, at 10 pg/mg for 6 and at 40 pg/mg for 2. The method was not considered validated for 5 NPS, as LLOQ resulted too high for a forensic analysis (80 pg/mg). Among authentic forensic samples, 17 tested positive for DoA, and 10 to NPS, most samples showing positivity for both. Detected NPS were ketamine and norketamine, 5-MMPA, ritalinic acid, methoxyacetyl fentanyl, methylone and RCS-4. CONCLUSION: The present methodology represents an easy, low cost, wide-panel method for the quantification of 122 NPS and 15 DoA, for a total of 137 analytes, in hair samples. The method can be profitably applied by forensic laboratories. Similar multi-analyte methods on the hair matrix might be useful in the future to study the prevalence of NPS and the co-occurrence of NPS-DoA abuse.

Beyond the distance between juridic and scientific decision-making process: An evidence-based prediction algorithm for professional liability assessment in healthcare-associated infections.

BACKGROUND: HAIs (Healthcare-Acquired-Infections) have been recently the subject of judgment n. 6386 pronounced on 3rd March 2023 by the Italian Supreme Court. This sentence provided three criteria to determine whether a health facility is responsible for the patient contracting a nosocomial infection, i.e. time criterion, topographical criterion and clinical criterion. Accordingly, the healthcare facility is obliged to prove the fulfillment of a series of preventive hygiene measures specifically detailed by the legislator. Herein, the positive predictive value of these criteria ("juridic criteria") in the identification of professional liability for nosocomial infections was evaluated in comparison with clinical criteria reviewed by Infectious Disease specialists ("Infectious-Disease criteria", i.e. presence of a Multidrug Resistant Organism (MDRO); development of surgical site infection; inadequate antibiotic therapy; inadequate disinfection). METHODS: Two retrospective cohorts were compared from the Portal of Telematic Services of the Ministry of Justice; 51 patients were extrapolated from Italian judgments concerning claims for Gram-negative nosocomial infections in the three-year period 2020-2022. On the other side, from the electronic database of University Hospital of Bari we extracted 349 patients affected by Gram-negative infections in the same timespan. Both "juridic" criteria and "Infectious-Disease" criteria were then applied to the full cohort after stratification for cohort of origin and after stratification for nosocomial or non-nosocomial infections. Predictive value of criteria was evaluated through receiver operating characteristic (ROC) curves and area under the curve (AUC). RESULTS: Overall, the incidence of definite nosocomial infections (according to final judgement or clinical records discharge letter) was 84 % in juridic cohort and 46 % in "real-world" series. Data suggested that the presence of all three juridic criteria [ROC AUC = 0.944 (95%CI = 0.924-0.963)] or the four clinical criteria [ROC AUC = 0.948 (95%CI = 0.928-0.969)] predicted well a case of nosocomial infection with professional liability. Moreover, by summarizing both criteria in a single classification system, the generated ROC curve (was the one with the highest AUC [0.9488 (95%CI = 0.928-0.969)]. Accordingly, further tests were performed, evaluating the predictive value of one juridic criterium plus at one of more Infectious-Disease criteria. Interestingly, the ROCs curves demonstrated that the presence of at least 1 juridic criteria plus at least 2 Infectious Disease criteria reached a predictive value comparable to 2 or 3 juridic criteria. CONCLUSIONS: The results highlight the efficiency of new criteria laid down in the judgment of the Italian Supreme Court to attribute liability for nosocomial infection despite the disputed distance between juridic and scientific decision-making process. In addition, the use of a combined score combining "juridic" and "Infectious-Disease" criteria provides a high-quality tool to be used by technical consultants to make up for lack of clinical documentation by passing judgments concerning litigation about professional liability in case of nosocomial infections. This sheds light on the possibility to face worldwide judicial inquiries with scientific rigor.

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.

Evaluation of a New DNA Extraction Method on Challenging Bone Samples Recovered from a WWII Mass Grave.

Bones and teeth represent a common finding in ancient DNA studies and in forensic casework, even after a long burial. Genetic typing is the gold standard for the personal identification of skeletal remains, but there are two main factors involved in the successful DNA typing of such samples: (1) the set-up of an efficient DNA extraction method; (2) the identification of the most suitable skeletal element for the downstream genetic analyses. In this paper, a protocol based on the processing of 0.5 g of bone powder decalcified using Na2EDTA proved to be suitable for a semi-automated DNA extraction workflow using the Maxwell® FSC DNA IQ™ Casework Kit (Promega, Madison, WI, USA). The performance of this method in terms of DNA recovery and quality was compared with a full demineralisation extraction protocol based on Qiagen technology and kits. No statistically significant differences were scored according to the DNA recovery and DNA degradation index (p-values ≥ 0.176; r ≥ 0.907). This new DNA extraction protocol was applied to 88 bone samples (41 femurs, 19 petrous bones, 12 metacarpals and 16 molars) allegedly belonging to 27 World War II Italian soldiers found in a mass grave on the isle of Cres (Croatia). The results of the qPCR performed by the Quantifiler Human DNA Quantification kit showed values above the lowest Limit of Quantification (lLOQ; 23 pg/µL) for all petrous bones, whereas other bone types showed, in most cases, lower amounts of DNA. Replicate STR-CE analyses showed successful typing (that is, >12 markers) in all tests on the petrous bones, followed by the metacarpals (83.3%), femurs (52.2%) and teeth (20.0%). Full profiles (22/22 autosomal markers) were achieved mainly in the petrous bones (84.2%), followed by the metacarpals (41.7%). Stochastic amplification artefacts such as drop-outs or drop-ins occurred with a frequency of 1.9% in the petrous bones, whereas they were higher when the DNA recovered from other bone elements was amplified (up to 13.9% in the femurs). Overall, the results of this study confirm that petrous bone outperforms other bone elements in terms of the quantity and quality of the recovered DNA; for this reason, if available, it should always be preferred for genetic testing. In addition, our results highlight the need for accurate planning of the DVI operation, which should be carried out by a multi-disciplinary team, and the tricky issue of identifying other suitable skeletal elements for genetic testing. Overall, the results presented in this paper support the need to adopt preanalytical strategies positively related to the successful genetic testing of aged skeletal remains in order to reduce costs and the time of analysis.

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.

Dying transfixing his own heart: a rare case of suicide by stabbing.

A 22-year-old man was found dead in his room, lying on his bed, with a kitchen knife embedded in his thorax. The external examination revealed only 1 deep incised horizontal wound in the third left intercostal space beside the sternum. There were no hesitation marks or defense injuries. On both flexor sides of the wrists, the forearms, and the arms and on the right and the left side of the neck, there were several old transversal cut scars. At the autopsy, once the single-edged knife was removed, and after a median sternotomy, the penetration depth of the stab wound revealed an incision of the left pleura, the pericardium, and the transfixed heart, from the anterior to the posterior side, ending on the seventh thoracic vertebra. Toxicological screening resulted as negative. Death occurred as a result of hemorrhagic shock after deep myocardial injuries. A psychiatric history of paranoid schizophrenia; the old scars, which were marks of previous attempted suicides; and the position of the weapon suggested that it was a suicide caused by a single strong stab wound in the cardiac region. This unusual manner of self-stabbing with a single stab to the heart without hesitation wounds was important to exclude other causes of death.

Denial of pregnancy and neonaticide: A historical overview and case report.

While denial of pregnancy and neonaticide are rare, they are potentially associated and share some risk factors. Neonaticide has been proposed as the extreme outcome of a denial of pregnancy. However, the process leading to such a possible outcome is not yet fully understood. The primary goal of this essay is to examine the various definitions and ambiguities surrounding the denial of pregnancy. The case of a young woman with a history of two denied pregnancies with diverse characteristics and outcomes, the latest of which resulted in neonaticide, is then reported and examined. A forensic psychiatric evaluation was also performed to reconstruct the woman's mental state at the time of the crime. The forensic pathological analysis of the newborn, abandoned near the sea while still alive, is described. The victim's body showed signs of shaken baby syndrome. We contend that differing levels of awareness during a denial of pregnancy might not be predictive of the potential delivery outcome in terms of threat to the newborn's survival, according to the forensic pathological and psychopathological data of the current case. Early identification of women affected by denial of pregnancy who pose a danger of committing infanticide is hampered by both intrinsic traits (dissimulation, unawareness, low propensity to seek assistance) and environmental factors (isolation, low socioeconomic level, poor education.). A previous history of denial of pregnancy should activate health and support services to reduce the potential risks for the mother and the child.

'Compressed Baby Head': A New 'Abusive Head Trauma' Entity?

BACKGROUND: Child abuse represents an important issue in the medico-legal and social context. In the last few decades, various aspects and mechanisms have been identified in child abuse case studies; however, constant research is needed in the field. With this paper, the authors will present a case of a new entity of Abusive Head Trauma that has come to the attention of medico-legal experts. DISCUSSION: The trauma analysis performed on the cranio-encephalic district of the baby revealed quite peculiar lesions that led the authors to exclude that the injuries had been solely caused by violent shaking of the baby's head, as suggested by Shaken Baby Syndrome. Instead, the authors hypothesised that another lesion mechanism had been added to this one, namely latero-lateral cranial compression. The comprehensive and exhaustive analysis of the case led the authors to present a new possible entity in child abuse trauma, namely 'Compressed Baby Head'. CONCLUSIONS: To the best of our knowledge, in the current literature, no similar clinical cases have ever been described. Thus, the case's uniqueness deserves to be brought to the attention of experts and the entire scientific community, as well as medical personnel, paediatricians, and reanimators. These professional figures are the first individuals who may encounter complex clinical cases such as the one presented in this paper; thus, they need to know how to properly manage the case and ensure protection for the abused infants and children.

Immune disturbance leads to pulmonary embolism in COVID-19 more than classical risk factors: a clinical and histological study.

COVID-19 induces endotheliitis and one of the main complications is enhanced coagulation. The incidence of pulmonary embolism (PE) in COVID-19 (CPE) has increased and clinical features for a rigorous analysis still need to be determined. Thus, we evaluated the clinical characteristics in CPE and the immune infiltration that occurred. Between January 1 and December 31, 2021, 38 patients were affected by CPE (9 ICU, 19 males/19 females, 70.18 ± 11.24 years) out of 459 COVID-19 cases. Controls were subjects who were evaluated for PE between January 1 2015, and December 31, 2019 (92 patients, 9 ICU, 48 males/45 females, 69.55 ± 16.59 years). All patients underwent complete physical examination, pulmonary computed tomography, laboratory tests, D-dimer, and blood gas analysis. There were no differences in laboratory tests or D-dimer. In patients with CPE, pO2, alveolar-arterial oxygen difference (A-aDO2), oxygen saturation %, and the ratio between arterial partial pressure of oxygen (PaO2) and fraction of inspired oxygen (FiO2), P/F, were significantly increased. There were no differences in PaCO2. Platelet count was inversely correlated to P/F (r = - 0.389, p = 0.02) but directly to A-aDO2 (r = 0.699, p = 0.001) only in patients with CPE. Histology of lung biopsies (7 CPE/7 controls) of patients with CPE showed an increase in CD15+ cells, HMGB1, and extracellular MPO as a marker of NETosis, while no significant differences were found in CD3+, CD4+, CD8+, and intracellular MPO. Overall, data suggest that CPE has a different clinical setting. Reduced oxygen content and saturation described in Patients with CPE should not be considered a trustworthy sign of disease. Increased A-aDO2 may indicate that CPE involves the smallest vessels as compared to classical PE. The significant difference in NETosis may suggest the mechanism related to thrombi formation.

Extraction of DNA from bones in cases where expectations for success are low.

To resolve cases involving unidentified cadavers, the study of polymorphic DNA markers of old bones is an invaluable but often challenging tool used in forensic genetics. Some of the difficulties encountered involve the limited quantity of endogenous DNA, its subsequent degradation (a result of elapsed time, environmental conditions, and the microorganisms that develop during the postmortem phase), and the coextraction of substances that inhibit amplification reactions. For these reasons, it is necessary to direct research toward the development of new extraction techniques with the goal of obtaining adequate quantities of high-quality DNA.The aim of this study was to improve the collection of extracted DNA compared with the amount of DNA obtained with the NucleoSpin DNA Trace Kit (Macherey Nagel) protocol for the extraction of genomic DNA from human bones. A modified version of the standard protocol is presented.The modified method for the extraction of genomic DNA, followed by amplification reaction, allowed for identification of 4 cadavers and typification of 1 cadaver. The study carried out involved unidentified cadavers, or their remains, discovered after a long period from time of death.

An Unusual Case of Fatal Thoracoabdominal Gunshot Wound without Diaphragm Injury.

In case of thoracoabdominal gunshot wounds (GSW), diaphragmatic lesions are common autopsy findings. In these cases, the bullet's path involves both the thorax and the abdomen, so the diaphragm (the muscle that separates the two cavities) is frequently damaged. In the present report we illustrate a very unusual autopsy finding, came up after a man was shot twice and affected by a lethal thoracoabdominal gunshot wound. In particular, as expected based on CT scans, the corpse exhibited a thoracic-abdominal path and a retained bullet in the abdomen, but no diaphragmatic lesions or hemorrhagic infiltrations of this muscle have been detected during the autopsy. After a scrupulous examination and the section of all the organs, the intracorporeal projectile's path was reconstructed, inferring that the thoracoabdominal transit of the bullet extraordinarily had occurred in correspondence of the diaphragmatic inferior vena cava's ostium, thus exploiting a natural passage without damaging the diaphragmatic muscle.

A fatal case of heart and pericardium rupture after non-penetrating chest trauma by road accident.

Heart lacerations following a non-penetrating chest trauma are rare events, few described in the literature. We report the case of a young woman who died just after a road accident, which determined a blunt thoracic trauma, with perforation of the right ventricle and the contiguous pericardium portion, and compound fractures of the sternum and the left ribs. The case presented is a rare evidence of indirect heart trauma, meaning that there was no correspondence between the chest impact/fracture site and the heart/pericardial lacerations.

Dental evidence of human remains of a Slavic soldier population deported in concentration camps during World War II.

Aims: The aim of this paper was to analyse post-mortem dental records of a collection of 93 skeletal remains exhumed from the ossuary of Bari Municipal Cemetery, Apulia, Italy. These skeletal remains belonged to Slavic soldiers deported in 1941 during World War II in two Italian concentration camps and who died in 1946-1947. Methods: A total number of 1949 teeth were analysed according to the American Board of Forensic Odontology and the WHO methods. The majority of the victims were men (95%) between the age of 18 and 62. Results: The results showed the dental health situation of a population of soldiers of World War II, in particular the high rate of caries (35%), periodontal disease (61%), and dental wear (65%) according to the high stress level of the soldiers during the armed conflict and the subsequent deportation. Conclusions: This is the first study reported in literature that analyses the effects of war and deportation on soldiers' pathological conditions of the oral cavity. This analysis also confirmed the usefulness of teeth for anthropological and forensic research thanks to their high resistance and preservation even after post-mortem modifications and different environmental factors.
