Toxicological investigations in a fatal and non-fatal accident due to hydrogen sulphide (H2S)poisoning

2019

Hydrogen sulphide (H2S) is one of the most toxic natural gas and represents a not rare cause of fatal events in workplaces. We report here a serious accidental poisoning by hydrogen sulphide inhalation involving six sailors. Three of them died while the other three survived and were transported to the emergency room. No greenish discolouration of the body, that could be a feature of these type of deaths, was observed at autopsy. Given that blood and/or urine H2S detection does not allow to discriminate if it is related to inhalation or to putrefactive processes, the determination of thiosulphate, H2S main metabolite, is decisive. The succession of fatal events reported here can be rebuilt b…

Caspase 9 and Caspase 3 Immunohistochemical Pattern in Skeletal and Cardiac Muscles at Different Times after Death: An Experimental Study on PMI Esti…

2021

(1) Background: The estimation of the post mortem interval (PMI) is a challenge for forensic pathologists because data emerging from methods commonly applied are not always conclusive, since several conditions exist that may affect the reliability of these parameters. Thus, new approaches have been proposed to overcome such a limit. In recent years, several studies have been performed on proteins analyzing their expression/degradation patterns in relation to the progressing of the post mortem interval. (2) Methods: The immunoreactivity patterns of two apoptosis mediators—Caspase 9 and Caspase 3—have been tested in order to evaluate their potential role as markers of the post mortem interval…

Forensic tools for the diagnosis of electrocution death: Case study and literature review

2018

Diagnosis of death by electrocution may be difficult when electric marking is not visible or unclear. Accordingly, the body of a man who appeared to have died from accidental electrocution was carefully forensically analysed. Macroscopic and microscopic analysis of the current mark was carried out using a variable-pressure scanning electron microscope equipped with energy dispersive X-ray microanalyser to highlight skin metallisation, indicating the presence of iron and zinc. The histological findings of electrocution myocardial damage were supported by the results of biochemical analysis which demonstrated the creatine kinase-MB and cardiac troponin I elevation. The effects of electric cu…

Analysis on sarcoglycans expression as markers of septic cardiomyopathy in sepsis-related death

2018

The post-mortem assessment of sepsis-related death can be carry out by many methods recently suggested as microbiological and biochemical investigations. In these cases, the cause of death is a multiple organ dysfunction due to a dysregulated inflammatory response occurring after the failure of infection control process. It was highlighted also that the heart can be a target organ in sepsis which determines the so-called septic cardiomyopathy characterized by myocardial depression. Several mechanisms to explain the pathophysiology of septic cardiomyopathy were suggested, but very few studies about the structural alterations of cardiac cells responsible for myocardial depression were carried…

Pitfalls on Postmortem Imaging: The Need of Blending Conventional and Virtual Autopsy on Burnt-Charred Body

2019

Joining forensic traditional autopsy and CT-MR postmortem virtual approach may assist forensic experts in adequate reconstruction of cause, manner, and way of death, significantly to find evidence of found wound/fracture and relative interpretation. Evaluation of criminal burning is often a difficult challenge in the view of misinterpretation of wound/fracture victims and usually poor case history of this criminal offense. In this scenario, a strong collaboration between imaging and classical forensic techniques is helpful.

Postmortem Imaging in Sudden Adult Death

2019

Several definitions of “sudden and unexpected death” exist. The World Health Organization definition is of natural death within 24 h from the onset of symptoms, but this is much too long for many clinicians and pathologists; some will only accept death within 1 h from the onset of illness. If the event was not witnessed, sudden death is defined as the interval between the time the subject was last seen and the time the body was found within 6 h.

Violence and Abuse: Battered Child

2019

Battered child is a crucial social and medical issue, which represents a major cause of morbidity and mortality among children. The ‘child abuse syndrome’ is a clinical condition in young children who have received serious physical abuse, and should be considered in any child exhibiting evidence of fracture of any bone, subdural haematoma, failure to thrive, soft tissue swellings or skin bruising, in any child who dies suddenly, or where the degree and type of injury is at variance with the history given regarding the occurrence of the trauma. A clinical-radiological-forensic collaboration is crucial for its identification.

Unexpected death for Takayasu aortitis associated with coronary ostial stenosis: case report.

2015

The differential diagnosis of vasculitis is often a difficult task due to the frequent morphological similarities that various vasculitic syndromes express when the heart is the target organ. The more the lesions are limited to the arterial tree with absent or almost silent coronary events, the less specific the anatomical and clinical frameworks. To create a series of clinical records and on the basis of these assumptions, the authors report a case concerning the sudden death of a 43-year-old woman which occurred while an ergonometric test was being carried out 28 days after the onset of the symptoms. A subsequent postmortem investigation/autopsy enabled us to detect a granulomatous aortit…

Hanging disguised as bondage: accidental or suicidal death?

2020

The concept of autoerotic asphyxiation refers to the use of devices or substances intended to enhance one's arousal by inducing cerebral hypoxia, which can involuntarily lead to death. Although in most cases death occurs accidentally, it is nonetheless true that the same devices might be used by the practitioners in order to attempt suicide. The case of a 34-year-old practitioner of autoerotic asphyxiation found dead in his apartment with bondage-like ligatures and masking is reported here. The case raised some issues concerning the accidental or suicidal nature of the act. The aspects taken into account in the management of the case are discussed, along with a compared approach to the data…

Fatal anaphylactic shock due to a dental impression material

2009

This study describes a case of fatal anaphylaxis that appeared immediately after the oral mucosa came into contact with an alginate paste used for dental impressions. The cadaveric examination and the poslmortem toxicology report confirmed that the cause of death was anaphylactic shock. The patient was affected by both cardiovascular and lung dlseases that worsened the condition and forbade the use of epinephrine. To the authors' knowledge, dental impression materials, and alginate in particular, have not been reported previously as being a cause of anaphylaxis

Unexpected death for takayasu aortitis associated with coronary ostial stenosis

2015

The differential diagnosis of vasculitis is often a difficult task due to the frequent morphological similarities that various vasculitic syndromes express when the heart is the target organ. The more the lesions are limited to the arterial tree with absent or almost silent coronary events, the less specific the anatomical and clinical frameworks. To create a series of clinical records and on the basis of these assumptions, the authors report a case concerning the sudden death of a 43-year-old woman which occurred while an ergonometric test was being carried out 28 days after the onset of the symptoms. A subsequent postmortem investigation/autopsy enabled us to detect a granulomatous aortit…

FATAL ANAPHYLACTIC SHOCK CEFTRIAXONE-INDUCED IN A 4 YEAR-OLD CHILD

2016

One of the most used cephalosporin in clinical practice is ceftriaxone. Anaphylaxis due to the administration of ceftriaxone is considered a rare event. Here, we report a case of fatal anaphylactic shock after the administration of ceftriaxone in a child who had tolerated the drug in past exposures. The allergic pathogenesis is sustained by the clinical data (short time between the inoculation of the drug and the onset of the symptoms; past exposure to the same molecule and probable sensitization) and the postmortem examination findings (polivisceral congestion and intense eosinophilia found in the histological examination).
