RESUMO

Sepsis is one of the major threats for the survival and prognosis of patients in intensive care units. In cases where detailed clinical data and monitoring is available, the diagnosis of sepsis is reliable. But when clinical data are incomplete or missing and sepsis is only suspected based on the autopsy results, the picture is often equivocal. This report describes the gross pathological findings obtained from the autopsy of a 48-year-old woman with Crohn's disease after surgical intervention. Macroscopically, we found intestinal perforation and signs of peritonitis. Histologically, the pulmonary/bronchial arteries were lined with E-selectin (CD 62E)-positive endothelial cells, which are an established postmortem histological marker of sepsis. We extended our investigations to the cerebral cortex and subcortical medullary layer. The endothelium of the cortical vessels and those in the cerebral medullary layer were likewise immunopositive for E-selectin. Furthermore, numerous TMEM119-positive, highly ramified microglial cell profiles were found in the grey and white matter. Microglial cells were lining the vascular profiles. In addition, TMEM119-positive microglial profiles were abundant in the cerebrospinal fluid (CSF). Multiorgan E-selectin positivity of the vascular endothelia provides further evidence for the postmortem diagnosis of sepsis.

RESUMO

Estimating time since death can be challenging for forensic experts, and is one of the most challenging activities concerning the forensic world. Various methods have been assessed to calculate the postmortem interval on dead bodies in different stages of decomposition and are currently widely used. Nowadays, the only well-recognized dating technique is carbon-14 radioisotope measurement, whereas other methods have been tested throughout the years involving different disciplines with different and sometimes not univocal results. Today, there is no precise and secure method to precisely determine time since death, and late postmortem interval estimation remains one of the most debated topics in forensic pathology. Many proposed methods have shown promising results, and it is desirable that with further studies some of them might become acknowledged techniques to resolve such a difficult and important challenge. The present review aims at presenting studies about the different techniques that have been tested in order to find a valuable method for estimating time since death for skeletal remains. By providing a comprehensive overview, the purpose of this work is to offer readers new perspectives on postmortem interval estimation and to improve current practice in the management of skeletal remains and decomposed bodies.

RESUMO

Toxicologists are often confronted with the abuse of multiple drugs and are obliged to decide which compound may have been the cause of death. We report on a 21-year-old man (182 cm, 84 kg), who was found unconscious in his bed. Beside him, the police found several controlled substances, among them were dried opium poppy pods containing thebaine, codeine and morphine, a clear liquid with the designer benzodiazepines flualprazolam and clonazolam and a white powder with the imprint SGT-25, instead of SGT-78 (CUMYL-4CN-BINACA). These compounds were also found in the urine sample following a non-targeted gas chromatography-mass spectrometry and a targeted liquid chromatography-tandem mass spectrometry (LC-MS-MS) screening approach. Subsequently, these compounds were quantified in whole femoral blood and scalp hair. Based on the concentrations measured in femoral blood in particular, we assume that the deceased had taken a lethal dose of the designer benzodiazepines-flualprazolam (0.74 mg/L) and clonazolam (2.08 mg/L), an extremely high dose of the opiates-thebaine (0.81 mg/L), codeine (0.23 mg/L) and morphine (0.13 mg/L ) and a high dose of the synthetic cannabinoid-CUMYL-4CN-BINACA (0.01 mg/L). Besides postmortem concentrations, we also present electron impact and electrospray ionization mass spectra of compounds found in the vicinity of the decedent, namely the tryptamines-4-hydroxy-N-isopropyl-N-methyltryptamine (4-HO-MIPT), 4-hydroxy-N-ethyl-N-methyltryptamine (4-HO-MET) and 4-acetoxy-N,N-diethyltryptamine (4-ACO-DET), the amphetamines-3-fluoroethamphetamine (3-FEA) and 2-fluoromethamphetamine (2-FMA) and the arylcyclohexylamines-N-ethyldeschloroketamine (O-PCE), 3-methoxyphencyclidine (3-MeO-PCP) and 3-methoxyeticyclidine (3-MeO-PCE).

RESUMO

Skin injuries caused by power drills have been rarely reported. A case is described of a 51-year-old woman who was found dead on a motorway after committing suicide by jumping from a bridge. The body showed a total of nine circular/oval penetrating injuries of the chest and abdomen with very regular, smooth margins, and particular features due to the presence of "skin islands" inside the lesion and "short radial linear abrasions" around the margins. These injuries were caused by a power drill, which was later found in the woman's apartment. For comparison, experimental tests were carried out with the same drill and different bits on pig skin, whose appearance resembled those found on the body. Especially skin islands were also reproduced in the experimental tests. The presented case shows the possibility of this rare method of suicide (or suicide attempt) and the typical characteristics of such peculiar skin lesions that pose problems of differential diagnosis with other injuries such as gunshot injuries.

RESUMO

During a helicopter exercise, due to the scarce visibility caused by the presence of snow, a collision between a landing helicopter and one already on the ground occurred. The 40-year-old pilot of the already landed aircraft was killed as a result of a direct propeller impact in the right side of the pilot's cockpit, while the co-pilot remained uninjured. At autopsy, the macroscopic characteristic findings in the form of cut injuries and amputations along the axis of the rotor blade impact as well as a 3D reconstruction through CT-Scan were analyzed and discussed for a thorough reconstruction of the injuries and the dynamics.

RESUMO

Gelsolin (GSN) is an actin-binding protein involved in cell formation, metabolism and wound closure processes. Since this protein is known to play a role in arthritis, here we investigate how the synovial membrane with its specific synoviocytes contributes to the expression of GSN and how the amount of GSN expressed is modulated by different types of arthritis. Synovial membranes from adult healthy subjects and patients with rheumatoid arthritis (RA) and osteoarthritis (OA) are analyzed by immunofluorescence, Western blot and ELISA. Macrophage-like synoviocytes (MLS) and fibroblast-like synoviocytes (FLS) were isolated, cultured and analyzed for their potential to produce and secrete GSN. In addition, the GSN concentrations in the synovial fluid of various forms of arthritis are determined by ELISA. GSN is produced by the healthy and arthritic synovial membranes. Both forms of synoviocytes (MLS and FLS) release GSN. The results show that there is a significant reduction in GSN in the synovial fluid in adult patients with OA. This reduction is also detectable in adult patients with RA but is not as evident. In juvenile arthritis, there is a slight increase in GSN concentration in the synovial fluid. This study shows that primary MLS and FLS express GSN and that these cells, in addition to articular chondrocytes, contribute to GSN levels in synovial fluid. Furthermore, GSN concentrations are modulated in different types of arthritis. Further studies are needed to fully understand how GSN is involved in joint homeostasis.

RESUMO

Hair samples are frequently analyzed in order to characterize consumption patterns of drugs. However, the interpretation of new psychoactive substance (NPS) findings in hair remains difficult because of lacking data for comparison. In this study, selected postmortem hair samples (n = 1203) from 2008 to 2020 were reanalyzed for synthetic cathinones, piperazines, phenethylamines, hallucinogens, benzodiazepines and opioids to evaluate prevalence data and concentration ranges. Hair samples were extracted using a two-step extraction procedure and analyzed using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Overall NPSs were detected in 381 cases (31.6%). Many cases were tested positive for more than one NPS in the same time span. A variety of NPS with a large range of concentrations was observed. For better comparability and interpretation of positive cases in routine work, quantitation data for 13 NPS were calculated as percentiles. The most frequently detected NPS in this study were N-ethylamphetamine, α-pyrrolidinovalerophenone, mephedrone, benzedrone, metamfepramone, and 4-fluoroamphetamine. In conclusion, a high prevalence of these drugs was observed from postmortem hair samples. The results show a growing use of many different NPSs by mainly young drug-using adults. Consequently, NPS screening procedures should be included in forensic toxicology. Our quantitative data may support other toxicologists in their assessment of NPS hair concentrations.

RESUMO

Unstable pelvic injuries are rare (3-8% of all fractures) but are associated with a mortality of up to 30%. An effective way to treat venous and cancellous sources of bleeding prehospital is to reduce intrapelvic volume with external noninvasive pelvic stabilizers. Scientifically reliable data regarding pelvic volume reduction and applicable pressure are lacking. Epidemiologic data were collected, and multiple post-mortem CT scans and biomechanical measurements were performed on real, unstable pelvic injuries. Unstable pelvic injury was shown to be the leading source of bleeding in only 19%. All external non-invasive pelvic stabilizers achieved intrapelvic volume reduction; the T-POD® succeeded best on average (333 ± 234 cm3), but with higher average peak traction (110 N). The reduction results of the VBM® pneumatic pelvic sling consistently showed significantly better results at a pressure of 200 mmHg than at 100 mmHg at similar peak traction forces. All pelvic stabilizers exhibited the highest peak tensile force shortly after application. Unstable pelvic injuries must be considered as an indicator of serious concomitant injuries. Stabilization should be performed prehospital with specific pelvic stabilizers, such as the T-POD® or the VBM® pneumatic pelvic sling. We recommend adjusting the pressure recommendation of the VBM® pneumatic pelvic sling to 200 mmHg.

RESUMO

AIMS: The aim of this study was to compare discrepancies between diagnosed and autopsied causes of death in 1,112 hospital autopsies and to determine the factors causing this discrepancies. METHODS: 1,112 hospital autopsies between 2010 and 2013 were retrospectively studied. Ante-mortem diagnoses were compared to causes of death as determined by autopsy. Clinical diagnoses were extracted from the autopsy request form, and post-mortem diagnoses were assessed from respective autopsy reports. Variables, such as sex, age, Body Mass Index, category of disease, duration of hospital stay and new-borns were studied in comparison to discrepancy. P-values were derived from the Mann-Whitney U test for the constant features and chi-2 test, p-values < 0,05 were considered significant. RESULTS: 73.9% (n = 822) patients showed no discrepancy between autopsy and clinical diagnosis. The duration of hospitalisation (6 vs. 9 days) and diseases of the cardiovascular system (61.7%) had a significant impact on discrepancies. CONCLUSION: Age, cardiovascular diseases and duration of hospital stay significantly affect discrepancies in ante- and post-mortem diagnoses.

RESUMO

New psychoactive substances are becoming increasingly popular. However, there is a lack of mass spectral information on parent substances and their corresponding metabolites as well as fatal concentrations in body liquids and tissues. Only very few clinical reports and user reports exist. This is also the case for methylaminopropylbenzofuran (MAPB) isomers. Urine from a decedent was screened using different immuno assays, gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-high resolution mass spectrometry (LC-HRMS/MS). Additionally, respective targets were quantitated in all analyzed specimens by LC-MS/MS. Gas chromatography-infrared spectroscopy (GC-IR) was applied to confirm the identity of the intoxication. GC-MS and the amphetamine immuno assay were useful to track the putative intoxication. However, the chemical structure of 2-MAPB was only elucidated by means of LC-HRMS/MS and GC-IR. 2-MAPB was highest in urine (167 µg/mL), followed by gastric content (98.9 µg/mL), bile fluid (30.8 µg/mL), liver (22.2 µg/g), heart blood (16.7 µg/mL), and lowest in femoral blood (7.3 µg/mL). Besides the parent substance, we detected N-demethyl-2-MAPB and hydroxy-2-MAPB in the urine sample. This case report presents an intoxication caused by 2-MAPB. The 2-MAPB concentration found in femoral blood exceeded those reviewed for 5/6-MAPB. The concentrations of the other specimens cannot be evaluated because there exist no comparative data. The values presented can be applied to assess 2-MAPB intoxications in the future.

RESUMO

Murder-suicides are defined as the murder of at least one person and the suicide of the offender following the murder. The intention to commit suicide must be primary. In most cases, a male offender kills a female victim after a separation. The current analysis was the first analysis of the typology of murder-suicides in Berlin. We analyzed the autopsy files of the Institute for Forensic Medicine of the Charité University Medicine Berlin and of the City Institute for Forensic Medicine Berlin. We performed descriptive and statistical analyses of cases between 2005 and 2013. We identified 17 murder-suicides. All 17 offenders were male, and 20 of the victims (90%) were female. The offenders used firearms in the majority of the cases. In seven cases, the victims and offenders were at least 80 years old. The average age of the offenders was 63 years. Disease was the motive in 6 cases involving older offenders. Our study might support the development of prevention strategies. In this regard, it is important to build a database for murder-suicides in Germany and other countries, to formulate a uniform definition of murder-suicide, to carry out nationwide interdisciplinary studies on this topic and to improve the existing health care structures, especially for older adults and people with depression.

RESUMO

The newly identified severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a pandemic respiratory disease. Moreover, thromboembolic events throughout the body, including in the CNS, have been described. Given the neurological symptoms observed in a large majority of individuals with COVID-19, SARS-CoV-2 penetrance of the CNS is likely. By various means, we demonstrate the presence of SARS-CoV-2 RNA and protein in anatomically distinct regions of the nasopharynx and brain. Furthermore, we describe the morphological changes associated with infection such as thromboembolic ischemic infarction of the CNS and present evidence of SARS-CoV-2 neurotropism. SARS-CoV-2 can enter the nervous system by crossing the neural-mucosal interface in olfactory mucosa, exploiting the close vicinity of olfactory mucosal, endothelial and nervous tissue, including delicate olfactory and sensory nerve endings. Subsequently, SARS-CoV-2 appears to follow neuroanatomical structures, penetrating defined neuroanatomical areas including the primary respiratory and cardiovascular control center in the medulla oblongata.

RESUMO

We describe and discuss the forensic mission after the terrorist attack on the Breitscheidplatz in Berlin on 19th December 2016, focusing on co-operation with police authorities, and the injury patterns of the deceased. Even after massive blunt trauma, severe injury patterns are often unrecognizable by visual inspection of the body ("Casper's sign"), which could instill false security among rescuers or, as happened on the Breitscheidplatz, may lead to distress or even trauma in rescue personnel when obviously primarily uninjured patients die suddenly.

RESUMO

In some rare cases of hanging, the so-called 'hangman's fracture' is observed. This occurs when a fall from height is associated with hanging, e.g. capital executions. We describe the case of an 81-year-old man who committed suicide by jumping off a bridge, with a rope wrapped around his neck. The combination of hanging and falling caused a series of bone fractures to the cervical spine and the hyoid bone, leading to dislocation of the vertebral column and multiple bone fragments, producing peculiar patterns. Computed tomography also identified a transverse full-thickness fracture of the dens, which is a rare event. This case highlights specific injuries associated with the combination of hanging and falling, and underlines the importance of a multidisciplinary approach in terms of radiological examination and complete autopsy.

RESUMO

New psychoactive substances (NPS)-such as synthetic cathinones and piperazines-are defined as substances designed to replicate the effects of traditional illegal drugs, including cocaine, ecstasy and amphetamines. These substances are known to potentially be much more potent than their analogs. In the past, there were many poisonings and deaths associated with NPS. Because of this, NPS identification and quantification have become more important in forensic toxicology. The present work aimed to develop, validate and apply a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method capable of detecting 35 synthetic cathinones and piperazines in hair samples. All target analytes were resolved in a 12 min run time and identified based on the quantifier ion, at least one product ion and the retention time. Depending on the analyte, the calibration curves were linear over a maximal range of 0.01-3 ng/mg. The limits of detection and quantification were within the ranges of 0.006-0.052 ng/mg and 0.008-0.095 ng/mg, respectively. The precision, bias and matrix effect were all within acceptable GTFCh thresholds and the method was free from interferences. The validated method was successfully used to identify synthetic cathinones and piperazines in authentic hair samples (n = 40) from forensic cases, demonstrating its suitability for the screening and quantification of a wide number of new stimulants in hair specimens.

RESUMO

Objective: It is known that recombinant human gelsolin (rhuGSN) supports wound closure and migration processes in avascular tissue. Since articular cartilage degradation plays an important role in osteoarthritis (OA), we are investigating how rhuGSN affects regeneration processes in human articular cartilage and represents a promising new therapeutic approach for the treatment of OA. Methods: Primary human chondrocytes (phCs) from articular knee cartilage were cultured with different concentrations of rhuGSN to analyse its direct effect in vitro. In addition, phCs were stimulated with 10 ng/mL IL-1ß or TNF-α to simulate osteoarthritis in vitro and treated with different concentrations of rhuGSN to investigate the beneficial effect in disease treatment. Cytokine secretion and gene expression as well as wound assays were performed. Results: GSN significantly promotes wound closure in phCs after 60 h compared to untreated cells. After 24 h treatment with 30 µg/mL rhuGSN, TGF-ß secretion increases significantly in the in vitro osteoarthritis model. Gene expression of MMP1 as well as SPARC is reduced in chondrocytes due to treatment with GSN in the OA model. At the same time, CXCR4 expression increases significantly after 24 h treatment with 3 µg/mL GSN. Conclusion: In the in vitro model of osteoarthritis, rhuGSN promotes wound closure of chondrocytes by a supported migration as well as expression of reconstructive and down regulated expression of deconstructive genes concentration dependently. Further experiments are needed to fully understand the beneficial effect of gelsolin on human chondrocytes and to verify this promising approach for a pharmacological treatment of osteoarthritis.

RESUMO

OBJECTIVE: Trefoil factor family peptide 3 (TFF3) has been shown to support catabolic functions in cases of osteoarthritis (OA). As in joint physiology and diseases such as OA, the synovial membrane (SM) of the joint capsule also plays a central role. We analyze the ability of SM to produce TFF compare healthy SM and its secretion product synovial fluid (SF) with SM and SF from patients suffering from OA or rheumatoid arthritis (RA). METHODS: Real-time PCR and ELISA were used to measure the expression of TFFs in healthy SM and SM from patients suffering from OA or RA. For tissue localization, we investigated TFF1-3 in differently aged human SM of healthy donors by means of immunohistochemistry, real-time PCR and Western blot. RESULTS: Only TFF3 but not TFF1 and -2 was expressed in SM from healthy donors as well as cases of OA or RA on protein and mRNA level. In contrast, all three TFFs were detected in all samples of SF on the protein level. No significant changes were observed for TFF1 at all. TFF2 was significantly upregulated in RA samples in comparison to OA samples. TFF3 protein was significantly downregulated in OA samples in comparison to healthy samples and cases of RA significantly upregulated compared to OA. In contrast, in SM TFF3 protein was not significantly regulated. CONCLUSION: The data demonstrate the production of TFF3 in SM. Unexpectedly, SF contains all three known TFF peptides. As neither articular cartilage nor SM produce TFF1 and TFF2, we speculate that these originate with high probability from blood serum.
