Trauma deaths in an Italian urban area: an audit of pre-hospital and in-hospital trauma care

In Italy, a comprehensive regional study of trauma deaths has never been performed. We examined the organization and delivery of trauma care in the city area of Milan, using panel review of trauma deaths. Two panels evaluated the appropriateness of care of all trauma victims occurred during 1 year, applying predefined criteria and judging deaths as not preventable (NP), possible preventable (PP), and definitely preventable (DP). Two hundred and fifty-five deaths were reviewed. Blunt trauma were 78.04% and motor vehicle crashes accounted for over 50%. Most victims (73.72%) died during pre-hospital settings and 91.1% died within the first 6h, principally because of central nervous system injuries in blunt and hemorrhage in penetrating trauma. Panels judged 57% of deaths NP, 32% PP, 11% DP (inter-panel K-test 0.88). Preventable deaths were higher after in-hospital admission. Main failures of treatment were lack in airway control or intravenous infusions in pre-hospital and mismanagement with missed injuries in emergency department. The high rate of avoidable deaths in Milan supports the need of trained pre-hospital personnel and of well equipped referring hospitals for trauma.

Whiplash-Associated Disorders: Clinical and medico-legal guidelines on the methods of ascertainment

A Novel Methodology for the Objective Ascertainment of Psychic and Existential Damage

Personal injury is a legal term for a physical or psychic injury suffered by the plaintiff under civil and/or tort law. With reference to non-pecuniary damages, the evidence itself of physical and/or psychic injury is not sufficient for damage compensation. The process of ascertaining impairments and/or disabilities which pertain to the “personal sphere” of the individual, such as pain and suffering, loss of amenity, and/or psycho-existential damage, poses particular difficulties in relation to the obtainment of scientific evidence. The “immateriality” and the subjective connotation of the personal sphere are, in themselves, critical issues. The clinical data obtained from the neuropsychological ascertainment find their essential prerequisite in the active participation of the examinee who, in legally relevant contexts (criminal law, civil law, insurance), may be “affected” by personal interests. The present manuscript presents a novel interdisciplinary methodology, experimented on a series of judicial and extra-judicial cases, aimed at the attainment of objectivity and accuracy eligible in relation to the judicial settlement of cases and other matters involving the ascertainment of peculiar aspects of non-pecuniary damage.

Measles Inclusion-Body Encephalitis: Neuronal Phosphorylated Tau Protein is Present in the Biopsy but not in the Autoptic Specimens of the Same Patient.

Tauopathies are sporadic or familial neurodegenerative diseases characterized by the accumulation of phosphorylated tau in neurons and glial cells and include encephalitis related to measles virus such as subacute sclerosing panencephalitis. We describe a 45‐year‐old woman, with a history of lymphoma treated with immunosuppressant therapy who underwent an open biopsy of the right frontal cortex for a suspect of encephalitis, and died 4 days later. The neuropathological assessment on the bioptic sample revealed edema, severe gliosis and microglial activation, with lymphomonocytic perivascular cuffing and neurons containing both nuclear and cytoplasmic eosinofilic inclusions that ultrastructurally appeared as tubular and curvilinear non‐membrane‐bound 12–18 nm structures, leading to the diagnosis of measles inclusion‐bodies encephalitis. The biopsy specimen showed several cortical neurons with intense perikaryal immunoreactivity for anti‐tau antibodies recognizing phosphorylated epitopes while on autoptic specimens no phosphorylated tau immunoreactivity was detected. Our findings suggest that in specific conditions biopsy‐derived human tau may be phosphorylated at sites that may result not phosphorylated in autopsy‐derived specimens, most likely caused by post‐mortem dephosphorylation.

Injury to the Thoracic Aorta Following Fatal Blunt Trauma: An Autopsy Study

Background:Transection of the thoracic aorta (TTA) remains a leading cause of death after blunt trauma. In this autopsy study, the natural history of this injury is reviewed.Patients and Methods:All blunt trauma deaths that occurred in the Milano urban area over a period of one year were collected. Autopsies were available in all cases. Incidence, mechanisms, anatomical locations of TTA, deaths due to TTA or coexisting injuries, and times of death were reviewed. Cause of death was established. Death was attributed to TTA if its abbreviated injury score was six (hemorrhage not confined to the mediastinum).Results:199 cases of fatal blunt trauma were included, 72% of which were males; mean age 53 ± 21. A TTA was observed in 53 subjects (27%), with a significantly higher incidence between the ages of 45 and 64 years and after falls from height. The aorta was transected at the isthmus in 36% of cases. Victims with TTA had a higher pre-hospital mortality and more injuries to chest organs, the chest wall and pelvis. In victims with TTA, injury to the aorta was the cause of death in 58%. Only five patients with TTA survived more than 1 h, reaching the hospital alive; four of these died due to the rupture of a mediastinal hematoma during the first hours of in-hospital care.Conclusions:This study demonstrates that TTA is a frequent cause of immediate deaths among blunt trauma victims. Patients with risk factors for TTA who reach the hospital alive need to be promptly investigated with a contrast CT scan. Evidence of mediastinal hematoma is suggestive for possible rapid evolution.

Management of psychogenic nonepileptic seizures (PNES): a multidisciplinary approach

The International League against Epilepsy (ILAE) proposed a diagnostic scheme for psychogenic non‐epileptic seizure (PNES). The debate on ethical aspects of the diagnostic procedures is ongoing, the treatment is not standardized and management might differ according to age group. The objective was to reach an expert and stakeholder consensus on PNES management. A board comprising adult and child neurologists, neuropsychologists, psychiatrists, pharmacologists, experts in forensic medicine and bioethics as well as patients’ representatives was formed. The board chose five main topics regarding PNES: diagnosis; ethical issues; psychiatric comorbidities; psychological treatment; and pharmacological treatment. After a systematic review of the literature, the board met in a consensus conference in Catanzaro (Italy). Further consultations using a model of Delphi panel were held. The global level of evidence for all topics was low. Even though most questions were formulated separately for children/adolescents and adults, no major age‐related differences emerged. The board established that the approach to PNES diagnosis should comply with ILAE recommendations. Seizure induction was considered ethical, preferring the least invasive techniques. The board recommended looking carefully for mood disturbances, personality disorders and psychic trauma in persons with PNES and considering cognitive‐behavioural therapy as a first‐line psychological approach and pharmacological treatment to manage comorbid conditions, namely anxiety and depression. Psychogenic non‐epileptic seizure management should be multidisciplinary. High‐quality long‐term studies are needed to standardize PNES management.

International Guidelines on the Methods of Ascertainment of Whiplash-Associated Disorders

International Guidelines on the Methods of Ascertainment of Personal Injury and Damage Under Civil-Tort Law

Compensation for personal damage, defined as any pecuniary or non-pecuniary loss causally related to a personal injury under civil-tort law, is strictly based on the local jurisdiction and therefore varies significantly across the world. This manuscript presents the first “International Guidelines on Medico-Legal Methods of Ascertainment and Criteria of Evaluation of Personal Injury and Damage under Civil-Tort Law”. This consensus document, which includes a step-by-step illustrated explanation of flow charts articulated in eight sequential steps and a comprehensive description of the ascertainment methodology and the criteria of evaluation, has been developed by an International Working Group composed of juridical and medicolegal experts and adopted as Guidelines by the International Academy of Legal Medicine (IALM). This chapter represents a slightly modified version of an article published in the International Journal of Legal Medicine.

The Holistic and Systematic Approach in Legal Medicine

After an overview of the subdisciplines and topics pertaining to bio-medicolegal sciences at an international level, the chapter illustrates the need for a systematic and holistic approach for the ascertainment and evaluation of personal injury and damage.
