Manual palpation to assess tissue stiffness is subjective. This study investigated whether biomechanical testing provides objective diagnostic value to assess tissue stiffness beyond time since death estimation. Brains from 44 adult autopsy cases were examined. Cylindrical samples from six different brain regions underwent oscillatory shear rheometry to determine storage, loss, and complex shear modulus. Cerebrospinal fluid and vitreous humor were analysed for glucose and lactate to calculate Traub sum values, and HbA1c was measured in venous blood when available. Autopsy reports were screened for medical history of diabetes mellitus and reported brain induration. Seven cases of the cohort had a known history of diabetes mellitus. Only one case of a known hyperosmolar hyperglycaemia prior to autopsy (Traub sum 636 mg/dl) was described as showing brain induration during autopsy. A second hyperosmolar hyperglycaemia case (Traub sum 458 mg/dl) also showed extreme stiffness but no reported induration. Both exhibited the lowest brain weights of the investigated cohort (1080 and 1120 g) and ranked among the top three stiffness values across all regions. Rheological stiffness significantly correlated with Traub sum values, but not with brain weight. Other causes of increased stiffness, such as traumatic brain injury with edema, produced high but regionally inconsistent values. Brain induration is associated with hyperosmolar hyperglycaemia rather than diabetes mellitus in general. Rheometry provided a sensitive, objective means to detect brain stiffening, whereas exceptionally stiff brains were not necessarily noted in autopsy reports based on routine manual palpation. KEY POINTS: • Brain stiffness seems to be associated with acute hyperosmolar hyperglycaemia rather than diabetes mellitus per se. • Diabetic cases without biochemical evidence of hyperosmolar hyperglycaemia showed no significant increase in brain stiffness. • Oscillatory shear rheometry provides an objective, quantitative measure of brain stiffness that outperforms manual palpation. • Rheologically measured brain stiffness correlated significantly with Traub sum values across all six examined brain regions. • Hyperosmolar hyperglycaemic cases showed consistently elevated stiffness across all brain regions.</p>","PeriodicalId":12449,"journal":{"name":"Forensic Science, Medicine and Pathology","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148720118","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}

We report a fatal case of phosphine poisoning following accidental exposure to aluminium phosphide (Phostoxin) in a 41-year-old electrician. Clinical, biochemical, autopsy, and toxicological findings were analyzed, with particular emphasis on classical qualitative toxicological methods. The patient collapsed at his workplace after entering a recently fumigated storage facility, resulting in accidental inhalation of phosphine gas. Laboratory investigations revealed severe metabolic acidosis (pH 6.81) with markedly elevated lactate concentrations (up to 25 mmol/L), indicating profound mitochondrial dysfunction. Biochemical findings demonstrated rapid progression of multiorgan failure, including severe myocardial injury, hepatic damage, renal failure, and coagulation abnormalities consistent with disseminated intravascular coagulation. Despite intensive treatment, the patient died 37 h after hospital admission. Forensic autopsy revealed nonspecific findings, including organ congestion and edema, while histological examination was limited by extensive postmortem autolysis. Toxicologicalanalysis of postmortem samples confirmed the presence of phosphine using classical qualitative reactions, including the silver nitrate and ammoniummolybdate tests.

However, interpretation of hymenal findings remains challenging because of anatomical variation and subtle genital injuries, creating the potential for misinterpretation in medico-legal assessments. This study aimed to characterize hymenal morphology, hymenal injuries, and related forensic findings among female child sexual abuse victims in Vietnam and to examine patterns associated with repeated abuse. A retrospective analysis was conducted using forensic examination records of female children under 16 years of age referred for suspected sexual abuse at a specialized medico-legal center. Sociodemographic characteristics, assault-related information, hymenal morphology, and genital and extra-genital injuries were extracted from standardized forensic reports. Cases with diagnostic uncertainty or complex forensic findings were reviewed through expert consultation, and final conclusions were established by consensus within the forensic assessment team. A total of 443 children were included, with a mean age of 13.3 ± 2.6 years. The median interval between the alleged assault and forensic examination was 19 days (IQR: 4-89 days). Repeated sexual abuse accounted for 68.4% of cases. In multivariable analysis, older age (aOR = 1.25, 95% CI: 1.14-1.37), parental divorce (aOR = 1.95, 95% CI: 1.15-3.30), and abuse occurring in private or semi-private settings were independently associated with repeated sexual abuse. The annular hymen was the most frequently observed morphology (60.3%). Overall, 69.3% of cases showed combined hymenal dilatation and tear, followed by tear only (19.6%) and dilatation only (6.3%), while 4.7% had no hymenal injury.

The present study identified fumarate hydratase (FH), a key tricarboxylic acid (TCA) cycle enzyme, as a potential biomarker associated with DMA and investigated its regulatory mechanism in the context of acute severe hypoxia. Western blot analysis of 87 human myocardial samples revealed that FH protein expression was significantly downregulated in DMA cases than in controls (hemorrhagic shock, brain injury, and other causes). These findings were independently validated by immunohistochemistry (IHC) in a separate cohort of 118 human samples. The diagnostic performance of myocardial FH, evaluated by receiver operating characteristic curve analysis, yielded an area under the curve of 0.8561, with 84.38% sensitivity and 70.93% specificity. In vitro experiments using AC16 cardiomyocytes revealed that hypoxia led to decreased FH expression at both the mRNA and protein levels, and this effect was reversed by the N-acetylcysteine antioxidant. FH downregulation resulted in significant accumulation of its substrate, fumarate, in human DMA myocardium, hypoxic cells, and culture medium. This subsequent accumulation of fumarate triggered the activation of the cytoprotective KEAP1-NRF2 pathway, as evidenced by NRF2 nuclear translocation and the upregulation of downstream antioxidant genes. Collectively, the present results support myocardial FH downregulation as a promising adjunctive biomarker associated with DMA and reveal a novel hypoxia-FH-fumarate-NRF2 axis, providing crucial insights into cellular responses to fatal hypoxic injury.

Detailed scene reconstruction and autopsy revealed heterogeneous limb positioning: some postures were attributable to biomechanical support, whereas others, particularly involving the hands, were not readily explained by environmental factors, object retention, or conventional postmortem changes. These findings may be better interpreted as reflecting terminal neuromuscular activity during a brief agonal phase, followed by stabilization of the resulting posture by early rigor mortis. A comparable suicidal hanging case demonstrated similar hand postures, providing additional observational support for this proposed interpretation. Overall, these observations are consistent with a hypothesis that apparent instantaneous fixation may represent a continuum of terminal neuromuscular phenomena rather than a distinct postmortem entity.
