The phenomenon of child abuse/maltreatment is underestimated and often represents a difficult challenge for healthcare professionals and forensic pathologists who must proceed with the differential diagnosis with accidental or self-induced events, or with lesions due to pathologies that overlap with that of mistreatment, defined as “Mimics”. This study presents a case series with the aim of discussing lesions that may mimic signs of physical abuse in children but are due to a different etiology to raise awareness and train healthcare professionals and forensic pathologists on possible confounding factors in order to avoid diagnostic errors. Six cases of “Mimics” out of 418 cases of suspected mistreatment (1.43% of cases) were identified, presenting skin lesions initially classified as injuries of abuse due to their location and type and, in particular, sexual abuse for three cases. Then, the lesions and the subjects, in particular the anamnestic history, were examined by a multidisciplinary team and the diagnosis of genital lichen sclerosus et atrophicus in three cases, and the results of popular healing techniques (i.e., “cupping”) in the other three cases were ascertained. These situations require specific skills and a forensic background from healthcare professionals to conduct a correct differential diagnosis and the intervention of a multidisciplinary team to investigate every possible pathology or alternative therapeutic practice that could simulate child abuse. In particular, when “mimics” are due to alternative medicine, it should not strictly be considered child abuse, but professionals must be aware of the hypothesis of mistreatment in case of non-medical indication or potential personal injuries from other crimes, such as illegal practice of the medicine. This awareness is also crucial to direct the child toward appropriate medical care, and it is essential to recognize that these conditions can coexist within the same clinical presentation.

Clostridium sordellii, which has recently been reclassified as Paeniclostridium sordellii and subsequently as Paraclostridium sordellii, is a rare human pathogen linked to infections of high morbidity and mortality, often presenting as fulminant toxic shock syndrome. Although most documented cases involve individuals with pre-existing health issues, such as immunosuppression and cancer, or those who have undergone specific gynecological procedures, there are few instances reported in otherwise healthy individuals. In this report, we present a case of fatality associated with P. sordellii infection in a young individual with a history of drug abuse, following post-mortem examinations. Additionally, we provide an updated review of the latest literature on this topic.

Background: Medical child abuse (MCA), previously known as Münchausen syndrome by proxy, involves the fabrication or induction of illness by caregivers—most commonly the mother—leading to unnecessary medical interventions and potential harm to the child. Methods: This retrospective study analyzed cases of suspected or confirmed MCA managed by the GAIA multidisciplinary team at Meyer Children’s Hospital, Florence, between 2010 and 2022. Cases were identified using Rosenberg diagnostic criteria and red flags outlined by the American Academy of Pediatrics (AAP) and the Royal College of Paediatrics and Child Health (RCPCH). Data were extracted from medical records and analyzed descriptively. Results: Among 816 cases of child maltreatment, 8 (0.99%) were identified as MCA. The median age of affected children was 5 years (range: 4–12 years), with a female predominance (6/8, 75%). All perpetrators were biological mothers (8/8, 100%). Children had a median of 23 emergency department visits (range: 4–44), with the most frequent presentations being fever (6/8, 75%), minor trauma (7/8, 87.5%), respiratory complaints (5/8, 62.5%), and gastrointestinal symptoms (4/8, 50%). According to Rosenberg criteria, 5 cases (62.5%) were classified as “possible diagnosis,” 1 (12.5%) as “definitive diagnosis,” 1 (12.5%) as “diagnosis by exclusion,” and 1 (12.5%) as “inconclusive.” Conclusions: Despite its low prevalence, MCA poses serious clinical and ethical challenges. Early detection requires thorough documentation, interdisciplinary collaboration, and improved access to shared medical records. The GAIA model offers a replicable framework for effective multidisciplinary management.

Background: This study examines the results of autopsy examinations specifically aimed at documenting complications arising from the implantation phase and treatment with veno–arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with refractory cardiac arrest. ECMO and VA-ECMO in particular are life-saving interventions that, in the case of cardiac arrest, can temporarily replace cardiac pump function. VA-ECMO is, however, a very invasive procedure and is associated with early mechanical, haemorrhagic, and thrombotic events, infections, and late multi-organ dysfunction. Aim: This research aims to evaluate autoptic and histologic findings in patients on VA-ECMO support, providing clinical and forensic evaluation elements with respect to the procedure and clinical settings. Materials and Methods: The study analysed 10 cases, considering variables such as the duration of cardiac arrest, understood as the time between the cardiac arrest event and reperfusion with VA-ECMO, the duration of VA-ECMO support, and any complications detected by clinicians during treatment. Results: The results highlighted the presence of numerous ischemic and haemorrhagic events affecting various organs. Among them, the intestines were particularly vulnerable, even after a short ECMO duration. Conclusions: ECMO was found to accelerate post-mortem decomposition, affecting post-mortem interval estimations, and cardiac damage from reperfusion, underlining the need to meticulously select indications for treatment with VA-ECMO and perform constant clinical evaluations during the treatment itself.

Background/Objectives: Accurate post-mortem interval (PMI) estimation remains challenging in forensic pathology. Although potassium (K⁺) is the most well-validated single biomarker in vitreous humor (VH), multivariate approaches may enhance precision by capturing the complex cascade of post-mortem biochemical changes. This study aimed to develop and validate a multivariate PMI estimation model incorporating three biochemical markers—potassium, ammonium (NH₄⁺), and albumin (ALB)—in vitreous humor using automated clinical chemistry platforms for practical forensic application. Methods: Vitreous humor samples from 38 autopsy cases with documented PMIs (39.5–285 h; mean, 105.5 h) were analyzed for K⁺ (Cobas C8000), NH₄⁺ (Cobas C8000), and ALB (Immage 800 nephelometry). Univariate and multivariate regression analyses were performed, with the residual standard error (RSE) as the primary measure of accuracy. Model validation was conducted by back-calculating PMI in four samples completely distinct from the training cohort. Results: All three analytes demonstrated strong individual correlations with PMI (R²: K⁺ = 0.88, ALB = 0.78, NH₄⁺ = 0.69; all p < 0.001). The multivariate regression model [PMI = 40.25[Alb] + 0.01573[NH₄⁺] + 5.339[K⁺] − 53.032] yielded an RMSE of ±15.5 h (MSE = 240.25 h²), outperforming potassium-only models (RMSE = ±22.6 h). Although NH₄⁺ showed limited statistical significance in the multivariate model (p = 0.128), its inclusion improved overall predictive accuracy. External validation in an independent cohort of four subjects (distinct from the 38 subjects in the training set) demonstrated a mean absolute error (MAE) of 20.4 h. Conclusions: The multivariate approach combining K⁺, NH₄⁺, and ALB in VH improves PMI estimation accuracy compared with single-marker methods. The use of automated clinical chemistry platforms enhances reproducibility and facilitates practical implementation in forensic laboratories.

Domestic violence against men remains significantly under-recognized, despite affecting 20–40% of men worldwide. Societal stigma, gender-normative expectations, and institutional biases often discourage help-seeking behaviors among male victims. This retrospective analysis characterizes domestic violence against adult men by examining victim–perpetrator dynamics, injury patterns, reporting behaviors, and behavioral barriers to help-seeking within an Italian emergency department setting. Overall, 80 adult male domestic violence victims presenting to the Emergency Department of Careggi University Hospital (Florence, Italy) between January 2017 and December 2022 were examined. Data included demographics, injury characteristics, perpetrator relationships, and formal reporting rates. Descriptive statistics and chi-square tests were used to examine associations between victim characteristics and help-seeking behaviors. The majority of victims were Italian men (age range 18–90 years, mean 44.2 ± 15.1); of these, 55% experienced IPV perpetrated by female partners. Physical injuries were predominantly minor (classified as minor according to ED prognosis ≤ 7 days) (78.8%), including abrasions and contusions affecting the head (52.5%), neck (28.8%), and upper limbs (41.3%). Formal reports were filed with judicial authorities in 58.8% of cases, yet only 15% accepted protective interventions. Visible facial injuries (OR = 3.85, 95% CI, p = 0.004) and female perpetrators (OR = 8.23, 95% CI, p < 0.001) were independent predictors of formal reporting. Documented behavioral barriers included stigma (68%), fear of disbelief (45%), and adherence to traditional masculine norms (52%). Our findings demonstrate that male domestic violence victims face substantial behavioral and systemic barriers that prevent help-seeking. Enhanced clinical–forensic training, gender-inclusive response protocols, and public awareness campaigns are essential to provide equitable support and reduce under-reporting.
