This study investigated headspace solid-phase microextraction (HS–SPME)–gas chromatography (GS)/mass spectrometry as a low-complexity method for accurate measurement of blood alcohol concentration (BAC) changes in humans over time following alcohol consumption. The aim was to develop an analytical method that would require as small blood samples as possible—smaller than that required for the conventional method—thereby reducing the burden on the subject. Polyethylene glycol (PEG) was used as the fiber material for SPME, and a DB-WAX capillary column was used for GC. For sample extraction via SPME, 50 µL of blood sample obtained via fingertip puncture was added to a vial already containing 3 mL of 20 % aqueous sodium chloride solution, following which an SPME fiber was inserted into the vapor phase (headspace) of the vial and heated at 70 ℃ for 20 min to sorb ethanol onto the fiber. The experiment for ethanol recovery in whole blood yielded recoveries of 71.1 % when spiked at 100 µg/mL and 95.1 % when spiked at 1000 µg/mL. Blood samples were obtained periodically with consent from a human volunteer who had actually consumed alcohol, and the BAC was shown to decrease with a peak 1.5 h after drinking, confirming the applicability of this method in BAC assessment when compared with the conventional Widmark method. Furthermore, the applicability of this method was also investigated in the case of saliva, which can be collected more easily and non-invasively than blood.
本研究研究了顶空固相微萃取(HS-SPME) -气相色谱(GS)/质谱法作为一种低复杂性的方法,用于准确测量人类饮酒后血液酒精浓度(BAC)随时间的变化。其目的是开发一种只需尽可能少的血液样本的分析方法——比传统方法所需的样本要少——从而减轻受试者的负担。聚乙二醇(PEG)作为SPME的纤维材料,DB-WAX毛细管柱用于气相色谱。通过SPME提取样品时,将通过指尖穿刺获得的50 µL血液样品加入到已经含有3 mL 20% %氯化钠水溶液的小瓶中,然后将SPME纤维插入到小瓶的气相(顶空)中,并在70℃下加热20 min以吸收乙醇到纤维上。全血乙醇回收率实验表明,添加浓度为100 µg/mL时,乙醇回收率为71.1 %;添加浓度为1000 µg/mL时,乙醇回收率为95.1% %。经实际饮酒的人类志愿者同意,定期采集血液样本,结果显示饮酒后BAC下降,峰值为1.5 h,与传统的Widmark方法相比,证实了该方法在BAC评估中的适用性。此外,还研究了该方法在唾液样本中的适用性,因为唾液样本比血液样本更容易采集且无创。

Understanding the motives behind femicides is crucial to design effective prevention strategies and to support women’s self-determination, free from threats to their mental and physical integrity.
We conducted a retrospective, multicenter forensic study involving 27 Italian Institutes of Legal Medicine, analyzing 1238 female homicides (1950–2023). Cases were classified as femicide or non-femicide female homicide according to the medico-legal definition of femicide as the murder due to the failure to recognize women’s right to self-determination. Motives were categorized into 12 groups, and relevant anamnestic and circumstantial data were collected.
Of the 1238 cases, 410 were identified as femicides, 395 as non-femicides, and 433 were excluded for insufficient information. Femicides were most frequently driven by jealousy/rejection (n = 185; 45.1 %) and separation/divorce (n = 144; 35.1 %), often in the context of intimate partner violence or inability to accept the end of a relationship. Non-femicides were predominantly associated with the perpetrator’s psychiatric disorder and/or drug addiction (n = 126; 31.9 %), violent aggression without gender-related motive (n = 69; 17.5 %), victim’s illness (n = 63; 15.9 %), or economic reasons (n = 58; 14.7 %).
In the Italian context, most femicides stem from relational dynamics − particularly jealousy, rejection, and separation − whereas non-femicides are more often linked to psychiatric illness, substance abuse, or non-gender-related aggression. Incorporating these findings into clinical risk assessment protocols, especially in emergency and primary care settings, may help identify women at high risk and guide targeted prevention strategies.
了解杀害妇女背后的动机对于设计有效的预防战略和支持妇女的自决至关重要,使其身心完整免受威胁。我们进行了一项涉及27个意大利法律医学研究所的回顾性多中心法医研究,分析了1950-2023年间1238起女性凶杀案。由于没有承认妇女的自决权,根据对杀害妇女的医学-法律定义,案件被划分为杀害妇女或非杀害妇女的女性杀人案。将动机分为12组,收集相关的记忆和环境数据。在1238起案件中,410起被确定为杀害妇女,395起被确定为非杀害妇女,433起因资料不足而被排除在外。杀害女性最常见的原因是嫉妒/拒绝(n = 185; 45.1%)和分居/离婚(n = 144; 35.1%),通常是在亲密伴侣暴力或无法接受一段关系结束的情况下。非杀害女性主要与犯罪者的精神障碍和/或吸毒成瘾(n = 126; 31.9%)、没有性别相关动机的暴力攻击(n = 69; 17.5%)、受害者的疾病(n = 63; 15.9%)或经济原因(n = 58; 14.7%)有关。在意大利的情况下,大多数杀害妇女的行为源于关系动力学,特别是嫉妒、拒绝和分离,而非杀害妇女的行为则更多地与精神疾病、药物滥用或与性别无关的攻击有关。将这些发现纳入临床风险评估协议,特别是在急诊和初级保健环境中,可能有助于确定高危妇女并指导有针对性的预防战略。

We developed a simultaneous analysis method for 13 neonicotinoids and related insecticides in whole blood by liquid chromatography-tandem mass spectrometry (LC-MS/MS) using a Novum simplified liquid extraction column. The extraction method, which employs an extraction solvent of 16% acetonitrile in ethyl acetate, demonstrated the best performance in terms of balancing phospholipid removal ability, recovery efficiency and matrix effects. Calibration curves showed good linear relationships, with r2 values exceeding 0.995. The intra- and inter-day accuracies and precisions were 85.5-108.8% and 0.2-13.0%, respectively. The recovery efficiencies were in the range of 52.7-92.7%. Matrix effects were between 60.6 and 201.0%; higher effects were seen for fipronil, which represents a significant challenge that resulted in substantial ion enhancement. Nevertheless, both the accuracy and precision of the method were enhanced by utilization of a stable isotopically-labeled internal standard followed by LC-MS/MS. The method was applied to a human postmortem blood sample collected during a forensic autopsy to demonstrate feasibility; results suggest that this method will be useful for forensic toxicological investigations.

建立了采用Novum简化萃取柱的液相色谱-串联质谱(LC-MS/MS)同时分析全血中13种新烟碱类及相关杀虫剂的方法。以乙酸乙酯为萃取溶剂,以16%乙腈为萃取溶剂的萃取方法,在平衡磷脂去除率、回收率和基质效应方面表现出最佳的萃取效果。校正曲线呈良好的线性关系,r2值均大于0.995。日内精密度为85.5 ~ 108.8%,日内精密度为0.2 ~ 13.0%。回收率在52.7 ~ 92.7%之间。矩阵效应在60.6% ~ 201.0%之间;氟虫腈的效果更高,这是一个重大挑战,导致了大量的离子增强。采用稳定同位素标记内标后的LC-MS/MS,提高了方法的准确度和精密度。该方法应用于法医尸检期间收集的人类死后血液样本以证明可行性;结果表明,该方法可用于法医毒理学调查。

We report a case of a minimally invasive autopsy using postmortem contrast-enhanced computed tomography (PMeCT) by direct large-vessel puncture combined with CT-guided myocardial biopsy as a novel method to determine the cause of death. The case involved a man in his 60 s who was found dead at his residence. Postmortem CT revealed a hematoma around the heart, suggesting the possibility of a post-myocardial infarction cardiac rupture or aortic dissection. PMeCT revealed contrast agent infiltration into the myocardium and leakage into the pericardium, indicating pericardial hematoma, likely due to cardiac rupture. A CT-guided percutaneous biopsy was performed on the area of contrast infiltration, and subacute myocardial infarction was observed 3-7 days after onset. Postmortem CT angiography provides detailed vascular images and is a valuable tool for evaluating pericardial hematomas and cardiac ruptures; however, the cost of the equipment and time constraints have limited its widespread use. To address these challenges, a relatively inexpensive technique called PMeCT by direct large-vessel puncture has been developed. To our knowledge, this is the first practical demonstration of combining PMeCT by direct large-vessel puncture with CT-guided myocardial biopsy in an actual forensic death investigation. This case illustrates how this minimally invasive approach can yield both radiological and histopathological insights, potentially offering a viable alternative in cases where a conventional autopsy is not feasible. As a supplementary report to our previous technical study, this case highlights the real-world applicability and diagnostic value of the technique, especially for identifying cardiac rupture.

我们报告了一例微创尸检,采用直接大血管穿刺的尸体对比增强计算机断层扫描(PMeCT)结合ct引导心肌活检作为确定死因的新方法。该案件涉及一名60多岁的男子,他被发现死在家中。死后CT显示心脏周围有血肿,提示心肌梗死后心脏破裂或主动脉夹层的可能性。pct示造影剂渗入心肌并渗漏至心包,提示心包血肿,可能是心脏破裂所致。ct引导下对造影剂浸润区行经皮穿刺活检,发病3-7天后观察到亚急性心肌梗死。死后CT血管成像提供了详细的血管图像,是评估心包血肿和心脏破裂的宝贵工具;然而,设备的成本和时间限制限制了它的广泛使用。为了解决这些挑战,一种相对便宜的技术被称为直接大血管穿刺的PMeCT。据我们所知,这是在实际法医死亡调查中首次将PMeCT直接大血管穿刺与ct引导心肌活检相结合的实际演示。这个病例说明了这种微创方法是如何产生放射学和组织病理学的见解,在传统尸检不可行的情况下,可能提供一种可行的替代方法。作为我们先前技术研究的补充报告,本病例强调了该技术在现实世界中的适用性和诊断价值,特别是在识别心脏破裂方面。

Percutaneous transhepatic biliary drainage (PTBD) is a widely utilized procedure for managing biliary obstructions, particularly in patients with unresectable pancreatic cancer. While generally effective, PTBD carries a risk of complications, including hemobilia, intra-abdominal hemorrhage, catheter-related issues, and, rarely, vascular injuries.
We present the case of a 90-year-old woman with pancreatic cancer who underwent PTBD for biliary obstruction. Shortly after the procedure, she developed hypovolemic shock and succumbed within hours. A forensic autopsy revealed a massive hemoperitoneum (2.5 L) resulting from a rupture of the inferior vena cava (IVC), an exceedingly rare complication of PTBD.
To our knowledge, this is the first reported case of an IVC rupture directly associated with PTBD. This case underscores the critical importance of operator expertise and meticulous technique during PTBD, as well as the need for heightened awareness of potential, albeit rare, vascular complications. It also highlights the role of autopsy in elucidating unexpected causes of death and in assessing procedural outcomes.
经皮经肝胆道引流术(PTBD)是一种广泛应用于胆道梗阻的治疗方法,特别是在无法切除的胰腺癌患者中。虽然通常有效,但PTBD有并发症的风险,包括胆道出血、腹腔出血、导管相关问题,以及罕见的血管损伤。我们提出的情况下,一个90岁的妇女胰腺癌谁接受PTBD胆道梗阻。手术后不久,她出现低血容量性休克,并在数小时内死亡。法医尸检显示,由于下腔静脉(IVC)破裂导致大量腹膜出血(2.5 L),这是一种非常罕见的PTBD并发症。据我们所知,这是第一例直接与PTBD相关的下腔静脉破裂。该病例强调了在PTBD过程中,操作人员的专业知识和细致技术的重要性,以及对潜在的血管并发症(尽管罕见)的高度认识的必要性。它还强调了尸检在阐明意外死亡原因和评估程序结果方面的作用。

Reports on the quantification of fluvoxamine (FLV) in human tissues have been quite limited, although FLV has been used as an antidepressant since 1986. Fluvoxamine acid (FLA) was shown to be the major metabolite of FLV in human urine in 1983, but its quantification is also limited to only three works using human plasma. The existence of desmethyl fluvoxamine (FLD) in human specimens was recently reported in 2025; therefore, its quantification has not yet been performed. Therefore, the present work deals with the quantifications of FLV, FLD and FLA in the human samples of blood, cerebrospinal fluid, pericardial fluid, bile, urine, liver, kidney and cerebrum obtained from a human cadaver; for the quantification, the standard addition method was employed using liquid chromatography–tandem mass spectrometry (LC–MS/MS). The three top concentrations of FLV, FLD and FLA were observed in bile > liver > cerebrum, bile > liver > kidney and bile > kidney > urine, respectively.

尽管氟伏沙明自1986年以来一直被用作抗抑郁药,但关于人体组织中氟伏沙明(FLV)定量的报告相当有限。氟伏沙明酸(FLA)在1983年被证明是人尿中FLV的主要代谢物,但其定量也仅限于使用人血浆的三个工作。最近在2025年报告了人类标本中存在去甲基氟伏沙明(FLD);因此,尚未对其进行量化。因此,本工作涉及从人体尸体中获得的血液、脑脊液、心包液、胆汁、尿液、肝脏、肾脏和大脑样本中FLV、FLD和FLA的定量分析;定量采用液相色谱-串联质谱法(LC-MS /MS)。FLV、FLD和FLA浓度最高的3个部位分别为胆肝脑、胆肝肾和胆肾尿。FLD/FLA的相对比值最高的三个部位出现在大脑、肝脏和胆汁中,最低的部位出现在尿液中,这可能是1983年用尿液检测FLV代谢物未能检测到FLD的原因之一。据我们所知,这是第一个通过LC-MS /MS对真实人体体液和固体组织中新的代谢物FLD进行有效定量的报告。

Background

Female genital injuries are often underreported or misinterpreted, particularly in cases of sexual violence. Until now, most research has focused on injuries caused by sexual intercourse, while injuries arising from everyday activities or anatomical variations have received less attention. This study aims to document genital injuries in healthy women, regardless of sexual assault, in order to contribute to an understanding of genital injury patterns and improve forensic interpretation.

Methods

A monocentric observational study was conducted including 100 healthy female volunteers (aged 20–70) who underwent a standardized external genital examination including photographic documentation. Data was analysed regarding the presence of injuries and anatomical variations, injury type, and affected anatomical structures. Injuries were categorized as erosions, lacerations, petechiae, and ecchymoses, excluding redness and swelling.

Results

Genital injuries were observed in 30% of the participants. Erosions and petechiae were the most common types of injuries, each accounting for 12% of all cases. In terms of the affected structures, the clitoris (32.4%) and the labia majora and minora (23.5% each) were most frequently affected.

Conclusion

This study provides valuable insights into the prevalence, distribution, and characteristics of genital injuries occurring in everyday life. Exposed structures, such as the clitoris and labia, are more susceptible to external accidental trauma compared to anatomically protected areas like the vaginal introitus. By providing information on the frequency of genital injuries, this study contributes to the understanding of genital injury patterns and will help improve forensic assessment in the future, particularly in cases of sexual violence.
女性生殖器官损伤往往被低估或误解,特别是在性暴力案件中。到目前为止,大多数研究都集中在性交引起的损伤上,而日常活动或解剖变异引起的损伤较少受到关注。这项研究的目的是记录健康妇女的生殖器损伤,无论性侵犯如何,以便有助于了解生殖器损伤模式并改进法医解释。方法采用单中心观察性研究方法,对100名年龄在20-70岁的健康女性志愿者进行了标准化的外生殖器检查,包括照片记录。数据被分析关于存在的损伤和解剖变异,损伤类型和受影响的解剖结构。损伤分类为糜烂、撕裂、瘀点和瘀斑,不包括红肿。结果30%的受试者出现生殖器损伤。糜烂和瘀点是最常见的损伤类型,各占所有病例的12%。在受影响的结构中,阴蒂(32.4%)、大阴唇和小阴唇(23.5%)最常见。结论本研究对日常生活中发生的生殖器损伤的患病率、分布和特征提供了有价值的见解。暴露的结构,如阴蒂和阴唇,比解剖学上受保护的区域,如阴道开口,更容易受到外部意外创伤。通过提供有关生殖器损伤频率的信息,这项研究有助于了解生殖器损伤模式,并将有助于改进未来的法医评估,特别是在性暴力案件中。

Dextromethorphan has antitussive effects and therefore is mainly used in over-the-counter cold remedies. However, abuse of this addictive substance as a ‘recreational drug’ has become problematic. We recently experienced two autopsy cases in which dextromethorphan intoxication likely contributed significantly to the cause of death. In one of these cases, the femoral vein blood concentration of dextromethorphan was in the lethal range (17.7 µg/mL), and death was considered to be solely due to poisoning with this drug. In the other case, the direct cause of death was hanging, but the dextromethorphan concentration was in the intoxication range (3.9 µg/mL), and through the associated abnormal behavior, may have contributed to the cause of death. In addition, multiple liquid and tissue samples from the autopsies of these two subjects were used to examine the distribution of dextromethorphan in the body by liquid chromatography–mass spectrometry.
右美沙芬有止咳作用,因此主要用于非处方感冒药。然而,滥用这种成瘾物质作为“娱乐性药物”已经成为一个问题。我们最近经历了两个尸检案例,其中右美沙芬中毒可能是导致死亡的重要原因。其中一例右美沙芬股静脉血药浓度处于致死范围(17.7µg/mL),死亡被认为完全是由于该药物中毒。另一例直接死因为上吊,但右美沙芬浓度处于中毒范围(3.9µg/mL),通过相关异常行为,可能是导致死亡的原因之一。此外,从这两名受试者的尸体解剖中提取的多个液体和组织样本通过液相色谱-质谱法检测了右美沙芬在体内的分布。

Acute thallium poisoning: An autopsy case report and review of the literature 急性铊中毒:尸检病例报告及文献复习

We report a case of death due to thallium (Tl) poisoning and discuss the findings with reference to the literature on Tl poisoning. A woman in her 20 s with a history of asthma developed symptoms such as coughing, vomiting, and fatigue, and visited a primary-care physician. She was rushed to another hospital on suspicion of an asthma attack, but her condition suddenly worsened and she died 3 days later. Postmortem computed tomography (CT) performed immediately before autopsy revealed high-density foreign material in the stomach and intestines. Autopsy findings revealed severe edematous changes under the skin and in various organs, and multi-organ failure was identified. In addition, large amounts of pleural effusion, severe pulmonary edema, pulmonary hemorrhage, and hyaline membrane formation in the lung tissue suggested acute respiratory distress syndrome (ARDS). Tl was detected in the blood at concentrations of 28.39–36.77 mg/L, about three times the lethal concentration. The cause of death in this case was thus determined to be ARDS caused by acute Tl poisoning. Many reports have described acute Tl poisoning affecting the lungs, as in this case. Generally, Tl is rarely included in toxicological analyses, but in cases such as this where ARDS is accompanied by severe pulmonary edema and a highly radio-opaque foreign material has been identified in the stomach or intestines on CT, Tl analysis using inductively coupled plasma mass spectrometry or other methods may facilitate determination of the cause of death.
我们报告一例铊中毒死亡病例,并参考有关铊中毒的文献讨论结果。一名20多岁有哮喘史的妇女出现咳嗽、呕吐和疲劳等症状,并去看了初级保健医生。她因怀疑哮喘发作被紧急送往另一家医院,但她的病情突然恶化,3天后死亡。尸检前立即进行的尸检计算机断层扫描(CT)显示胃和肠内有高密度的异物。尸检结果显示皮肤下和各器官有严重的水肿变化,并确定了多器官衰竭。大量胸腔积液、严重肺水肿、肺出血、肺组织形成透明膜提示急性呼吸窘迫综合征(ARDS)。血液中检测到的Tl浓度为28.39 ~ 36.77 mg/L,约为致死浓度的3倍。因此,本病例的死亡原因确定为急性急性呼吸窘迫综合征。许多报告描述了急性铊中毒影响肺部,如本例。一般来说,毒性分析很少包括Tl,但在这种情况下,ARDS伴有严重肺水肿,CT上在胃或肠中发现高度放射性不透明的异物,使用电感耦合等离子体质谱法或其他方法进行Tl分析可能有助于确定死亡原因。

Background

Post-mortem microbial communities (microbiota and microbiome) have emerged as promising tools for forensic investigations, particularly in estimating the post-mortem interval (PMI). However, experimental variability in sampling protocols, analytical methods, and reporting standards has limited the comparability and reproducibility of findings across studies.

Methods

A systematic review was conducted in accordance with PRISMA guidelines to evaluate the current literature on human post-mortem microbiota and microbiome. Inclusion criteria focused on studies that examined microbial communities in human cadavers using culture-based techniques, next-generation sequencing (NGS), or both. Data were extracted regarding sample types, microbial targets, analytical methods, decomposition stages, insect activity, and study objectives.

Results

A total of 24 studies were included, revealing substantial heterogeneity in methodological approaches. NGS techniques dominated recent literature, targeting bacterial 16S rRNA gene sequences to characterize microbial succession during decomposition. While some studies have shown promising correlations between microbial taxa and PMI, the inconsistent use of controls and variable decomposition conditions impeded cross-study comparisons. Culture-based approaches were generally limited to early investigations and provided narrower taxonomic resolution.

Conclusions

Despite encouraging results, the forensic application of post-mortem microbiome and microbiota remains hindered by methodological inconsistencies and a lack of standardization. Establishing unified protocols and adopting interdisciplinary approaches will be essential for validating microbial signatures as reliable forensic tools.
死后微生物群落(微生物群和微生物组)已成为法医调查的有前途的工具,特别是在估计死后间隔(PMI)方面。然而,采样方案、分析方法和报告标准的实验可变性限制了研究结果的可比性和可重复性。方法按照PRISMA指南进行系统综述,对目前有关人类死后微生物群和微生物组的文献进行评价。纳入标准侧重于使用基于培养的技术、下一代测序(NGS)或两者兼而有之检测人类尸体微生物群落的研究。提取有关样品类型、微生物目标、分析方法、分解阶段、昆虫活动和研究目的的数据。结果共纳入24项研究,揭示了方法学方法的巨大异质性。NGS技术在最近的文献中占主导地位,针对细菌16S rRNA基因序列来表征分解过程中的微生物演替。虽然一些研究表明微生物分类群与PMI之间存在有希望的相关性,但不一致的对照使用和可变的分解条件阻碍了交叉研究比较。基于文化的方法通常仅限于早期调查,并提供较窄的分类解决方案。结论尽管取得了令人鼓舞的结果,但尸检微生物组和微生物群的法医应用仍然受到方法不一致和缺乏标准化的阻碍。建立统一的协议和采用跨学科方法对于验证微生物特征作为可靠的法医工具至关重要。
