Role of Imaging in the Assessment of Age Estimation
2019
Age assessment by skeletal age estimation of unknown individuals is of paramount importance in forensic science, both for assessing imputability (if the author of a crime is old enough to be tried and judged), both in case of unaccompanied minors, or whether refugees and asylum seekers are adults or juveniles, which implies different legal issues and procedures. The aim of this article is to review the age estimation methods used in forensic practice.
Virtopsy and Living Individuals Evaluation Using Computed Tomography in Forensic Diagnostic Imaging
2019
The applications of forensic radiology involve both Virtopsy both studies on living people - to demonstrate bone age, search for foreign bodies, such as voluntary injection of drug ovules or surgical sponges accidentally forgotten, to assess gunshot wounds, to evaluate injuries by road accidents, and cases of violence or abuse (both in adults and in children). Computed tomography is the most used imaging tool used in forensic pathology and its indications are mainly focused on cases of unnatural deaths or when a crime is suspected. It is preferred over the standard autopsy in selected cases, such as in putrefied, carbonized or badly damaged bodies; or as a preliminary evaluation in mass dis…
When a virus (Covid-19) attacks human rights: The situation of asylum seekers in the medico-legal setting
2020
The Covid-19 pandemic is a global health emergency that requires immediate, effective action by governments to protect the health and basic human rights of everyone’s life. Refugees and migrants are potentially at increased risk because they typically live in overcrowded conditions often without access to basic sanitation. Since the beginning of the official lockdown for Covid-19, the medico-legal assessment of physical violence related to obtaining status or other forms of human protection has been frozen.
Cardiac rupture caused by traffic accident: Case reports and a literature review.
2018
The commonest cause of blunt cardiac injuries is from traffic accidents followed by violent falls, sport activities, accidents or a fight but rupture of the heart is rare and lethal. The precise incidence of cardiac injury after a blunt chest trauma is unknown as rates vary greatly in the literature from between 7% and 76% of cases. Autopsy studies have shown that the right ventricle is the most frequently ruptured, followed by the left ventricle, right atrium, intraventricular septum, left atrium and interatrial septum with decreasing frequency. Post-mortem imaging is a rapidly advancing field of post-mortem investigations of trauma victims. The available literature dealing with the compa…

The medico-legal implications in medical malpractice claims during Covid-19 pandemic: Increase or trend reversal?
2020
The Covid-19 pandemic caused a marked increase in admissions to intensive care units. The critically ill patients’ condition from the infection resulted in their deaths. The healthcare facilities have got into trouble because of the pandemic. In fact, they had to create additional beds in a very short time and to protect health workers with personal protective equipment. Healthcare professionals fear that there will be an increase in complaints and medico-legal malpractice claims and hence they have urged politicians to discuss this. The Italian Parliament recently debated the topic of medical liability and passed the Decree-Law no. 18 of 17 March 2020 (DL – so called Cura Italia) by which…

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…
Role of virtopsy in the post-mortem diagnosis of drowning.
2014
Purpose: Due to admitted limits of autopsy-based studies in the diagnosis of drowning, virtopsy is considered the new imaging horizon in these post-mortem studies. The aim of our study was to evaluate the role of virtopsy performed through computed tomography (CT) in the forensic diagnosis of drowning. Materials and methods: We retrospectively examined the CT data of four cadavers recovered from sea water and suspected to have died by drowning. Each patient underwent a full-body post-mortem CT scan, and then a traditional autopsy. Conclusion: To date, there are no autopsy findings pathognomonic of drowning. This study proves that virtopsy is a useful tool in the diagnosis of drowning in tha…
Capillary electrophoretic and extraction conditions for the analysis of Catha edulis FORKS active principles
2013
A capillary electrophoretic method, which allowed the detection and separation of the active principles of Catha edulis, i.e. cathinone, cathine and phenylpropanolamine, was developed. A suitable internal standard (nicotinamide), which permitted the quantification of the analytes reducing the variability of the migration times due to EOF changes, was identified. The analytical method was validated, assessing linearity, sensitivity and repeatability, showing optimal features for the analysis of the vegetable material. Moreover extraction conditions were investigated to achieve the exhaustion of the plant material in the fastest and most efficient way to meet the requirements of the Court.

Development and validation of a reliable method for studying the distribution pattern for opiates metabolites in brain
2012
Abstract Brain distribution pattern of “street” heroin metabolites (morphine and codeine) was investigated in two fatalities due to “acute narcotism”. A suitable sample pretreatment prior to solid-phase-extraction was developed to achieve a good recovery of the analytes and to eliminate the interfering species. After derivatization with MSTFA, samples were analyzed by GC/MS. Specificity, accuracy, precision and linearity of the method were evaluated; LOD and LOQ were, respectively, 10 ng/25 ng for morphine and 5 ng/10 ng for codeine. This method was applied to the analysis of six brain areas (hippocampus, frontal lobe, occipital lobe, nuclei, bulb and pons) coming from two cases of heroin-r…
ustione corneale durante intervento di facoemulsificazione: contributo casistico e considerazioni medico-legali
2014
[Corneal burn during phacoemulsification surgery: case report and medico-legal considerations] The authors report a case of severe corneal burn, occured a few seconds later the beginning of the surgical procedure of phacoemulsification on a 63 years old woman affected by cataract. The authors analyzed the case as a result of claims for damage to the surgeons and the hospital by the patient. In terms of assessment of responsibility, medico-legal investigation is aimed at identifying whether the responsibility of the event of damage to the patient is to be attributed to the negligent conduct of the surgeon or to defects or damage to the equipment used by the same. The authors underline the im…
Telemedicine during Covid-19 pandemic: Advantage or critical issue?
2020
Telemedicine offers a support to traditional medicine, delivering clinical services when distance is a critical factor. Although this tool does not replace a medical examination, during Covid-19 pandemic, it reduces the spread of infection and avoids the need for a patient’s visit. It is useful in the management of chronic disorders or for patients undergoing palliative treatment. The University Hospital of Palermo has applied this in cases of chronic illness caring for patients who cannot stop their treatment, such as Department of Onco-Haematology, Internal Medicine, Dermatology, etc. The Department of Legal Medicine of Palermo, in particular, is also using telemedicine to manage medico-…

Unexpected variation of the codeine/morphine ratio following fatal heroin overdose.
2014
Postmortem samples from 14 cases of suspected heroin overdose were subjected to a preliminary systematic toxicological analysis in order to highlight the presence of unknown exogenous compounds (e.g., drugs of abuse, alcohol) that may have played a role in the mechanism of death. This analysis unveiled histories of poly-drug use in seven of the cases under investigation. Moreover, the concentrations of morphine and codeine in the brain were also investigated, and the results were compared with the data obtained from the blood specimens. The concentration of morphine in blood ranged from 33 to 688 ng/mL, while the concentration of codeine ranged from 0 to 193 ng/mL. However, in the brain, th…
Allele frequencies distribution of 16 forensic STR loci in a Western Sicilian population sample
2017
Abstract The PowerPlex® ESI 17 Fast and ESX 17 Fast Systems represent faster cycling versions released by Promega® to follow the requirements of ENFSI and EDNAP groups’ for new STR genotyping systems in Europe. Allele frequencies and forensic parameters were estimated in a population sample of 120 unrelated healthy individuals living in Sicily (Western Sicilian population sample) using PowerPlex® ESI 17 Fast and PowerPlex® 17 Fast Systems. Full concordance of the results for both systems was observed. No significant deviation from Hardy-Weinberg equilibrium was detected. The observed heterozygosity changed from 0.85833 for FGA to 0.95 for TH01. The combined power of discrimination for the 1…
Determination of propofol by GC/MS and fast GC/MS-TOF in two cases of poisoning
2017
Two cases of suspected acute and lethal intoxication caused by propofol were delivered by the judicial authority to the Department of Sciences for Health Promotion and Mother-Child Care in Palermo, Sicily. In the first case a female nurse was found in a hotel room, where she lived with her mother; four 10 mg/mL vials and two 20 mg/mL vials of propofol were found near the decedent along with syringes and needles. In the second case a male nurse was found in the operating room of a hospital, along with a used syringe. In both cases a preliminary systematic and toxicological analysis indicated the presence of propofol in the blood and urine. As a result, a method for the quantitative determina…
SAFETY CONSIDERATIONS ON TEENAGE PEDESTRIAN-BUS IMPACT
2019
This work studies the impact conditions between the adolescent pedestrian and the bus focusing on head and chest injury. The injury to the head is analyzed using both the Head Injury Criterion (HIC) 36 and the HIC15 parameters as established by the most advanced legislation and comparing the risk probability Abbreviated Injury Scale (AIS3+) and AIS4+. The parameter HIC15 gives a higher probability of risk with lower values, and therefore it can be considered more conservative. Moreover, the study of chest injury is performed with two different biomechanical parameters: the Thoracic Trauma Index (TTI) and the TTI(d); the last neglects the pedestrian mass. The results indicate that the param…
