This form of abuse is particularly serious and difficult to diagnose. Worldwide, it is estimated that 0.5 to 1.2 per 100,000 children are abused in this way every year. We report the case of FDP in an 8-year-old child who presented with coagulation disorders secondary to the unknowing administration of Acenocoumarin. His parents had requested seven medical consultations over a six-month period. The parents systematically reported a coagulation pathology (factor VII deficiency), prompting further investigations and treatment. Biological tests showed deficiencies of vitamin K-dependent coagulation factors, raising suspicion of vitamin K antagonists (VKA) use. Toxicological tests revealed the presence of Acenocoumarin in the child's blood three times, at levels of 0.15 mg/L; 0.06 mg/L and 0.43 mg/L. The biological abnormalities corrected spontaneously after the child was hospitalized. A family investigation led to the diagnosis of medical child abuse in the child's older sister, who presented bleeding.

This study analyzes GSR distribution from 9 × 19 mm ammunition along the trajectory with a fixed target. GSR particle count follows a bell-shaped distribution, influenced by velocity, temperature, and burn rate. Understanding this pattern aids in modeling GSR dispersion based on muzzle-to-target distance, improving forensic analysis of shooting incidents. The kinematic behavior of GSR particles observed in this study facilitated the identification of the region exhibiting the highest deposition. The peak particle deposition was detected along the projectile trajectory, specifically at 100-130 cm from the muzzle end, in the direction of fire. This facilitated the identification of the distance at which the probability of obtaining maximum GSR particles is possible. This aids forensic investigations, providing insights into the trajectory, and identifying the potential region of maximum GSR deposition. A significant influence of distance on the number of GSR particle deposition was observed in the study. The study highlights the necessity of GSR collection along the trajectory, where retrieval probability is higher than at the muzzle or target. A methodology using the Trasoscan Laboratory Imaging System (TLIS) for GSR detection and counting is proposed. TLIS demonstrates potential as a primary imaging tool, with analytical data represented as particle frequency in the shooting vicinity. SEM analysis reveals significant deviations in GSR size distribution across muzzle, trajectory, and target, enhancing accuracy by identifying GSR-dense areas for more precise forensic conclusions. The largest GSR particles were recovered from the target distance (470-500 cm), suggesting surface modifications upon impact, which can be instrumental in estimating the shooting distance. The proposed approach could be implemented in current analytical pipelines or caseworks.</p>","PeriodicalId":12449,"journal":{"name":"Forensic Science, Medicine and Pathology","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143614313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pulmonary thromboembolism (PT) is a leading cause of sudden death, often requiring medicolegal evaluation. While thrombus formation is primarily explained by Virchow's triad, the distinction between antemortem, agonal, and postmortem clot (PMC) pathogenesis remains debated.

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.
