It is all about the insects: a retrospective on 20 years of forensic entomology highlights the importance of insects in legal investigations.

This study highlights the importance of insect evidence by evaluating 949 insect-associated cases, including 139 entomological reports, from 2001 to 2019 at the Institute of Legal Medicine Frankfurt/Germany. With a high number of cases in the summer months and a low number in the colder season, 78.5% of the bodies were found indoors, regardless of year or month.

hFRUIT: An optimized agent for optical clearing of DiI-stained adult human brain tissue.

Here, we describe a new immersion-based clearing method suitable for optical clearing of thick adult human brain samples while preserving its lipids and lipophilic labels such as 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI). This clearing procedure is simple, easy to implement, and allowed for clearing of 5 mm thick human brain tissue samples within 12 days. Furthermore, we show for the first time the advantageous effect of the Periodate-Lysine-Paraformaldehyde (PLP) fixation as compared to the more commonly used 4% paraformaldehyde (PFA) on clearing performance.

Interdisciplinary teaching and training - A medicolegal specialty.

The Frankfurt model is described to exemplify the teaching and training concepts implemented at the Institute of Legal Medicine in Frankfurt am Main up to 2015. The Frankfurt model describes a comprehensive, networked teaching system aiming at an interdisciplinary training. Interdisciplinarity is a domain of forensic medicine as a broadly diversified subject related to various scientific disciplines.

Automatic Segmentation of Human Cortical Layer-Complexes and Architectural Areas Using Diffusion MRI and Its Validation.

Recently, several magnetic resonance imaging contrast mechanisms have been shown to distinguish cortical substructure corresponding to selected cortical layers. Here, we investigate cortical layer and area differentiation by automatized unsupervised clustering of high-resolution diffusion MRI data. Several groups of adjacent layers could be distinguished in human primary motor and premotor cortex.

Histological validation of high-resolution DTI in human post mortem tissue.

Diffusion tensor imaging (DTI) is amongst the simplest mathematical models available for diffusion magnetic resonance imaging, yet still by far the most used one. Despite the success of DTI as an imaging tool for white matter fibers, its anatomical underpinnings on a microstructural basis remain unclear. In this study, we used 65 myelin-stained sections of human premotor cortex to validate modeled fiber orientations and oft used microstructure-sensitive scalar measures of DTI on the level of individual voxels.

[Legal aspects of spondylosis].

Prior to a medical intervention (and also when omitted) it is important to implement the prerequisites for medical treatment as formulated by the legislation during the last decades. Essential points are the timely and comprehensive clarification and informed consent of the patient on diagnosis, therapy, complications and aftercare. The case described here substantiates the essential points which must be considered with respect to operative activities in the interests of the patient as well as the treating physicians.

MIF Receptor CD74 is Restricted to Microglia/Macrophages, Associated with a M1-Polarized Immune Milieu and Prolonged Patient Survival in Gliomas.

The macrophage migration inhibitory factor (MIF) receptor CD74 is overexpressed in various neoplasms, mainly in hematologic tumors, and currently investigated in clinical studies. CD74 is quickly internalized and recycles after antibody binding, therefore it constitutes an attractive target for antibody-based treatment strategies. CD74 has been further described as one of the most up-regulated molecules in human glioblastomas.

Nephropathy in illicit drug abusers: a postmortem analysis.

Background: Illicit drug abuse is an independent risk factor for chronic kidney disease, but the pathogenic consequences of long-term exposure to illicit drugs and contaminants under unsterile conditions remains unclear.

Study Design: Case series.

Setting & Participants: All deceased persons (n 5 129) who underwent forensic autopsy because of suspected connection with illicit drug abuse between January 1, 2009, and April 30, 2011, in Frankfurt/Main, Germany.

Single coronary artery: a fatal R-I type.

Coronary artery anomalies are found in approximately 1.3 % of symptomatic adult patients undergoing coronary arteriography and encompass a wide variety of anatomic patterns. Single coronary arteries are found in 0.

Scalar localization by computed tomography of cochlear implant electrode carriers designed for deep insertion.

Objectives: This study aimed to evaluate the possibility of predicting radiologically the scalar localization of a 31.5-mm-long, free-fitting electrode carrier for cochlear implantation, using conventional planar computed tomography.

Study Design: A cross-sectional human temporal bone study was conducted.

[Reform of forensic autopsy in the German Code of Criminal Procedure].

The Federal Ministry of Justice has presented another proposal to rephrase the wording of Section 87 of the German Code of Criminal Procedure (StPO). The new version of Section 87 StPO is to be rejected as it would lead to a loss of institutional and professional standards. The bill is clearly influenced by a tendency towards privatisation for the benefit of a small group of specialists in forensic medicine mostly organised in limited liability companies and thus at the expense of institutes of legal medicine affiliated to universities or physicians working in the forensic service of regional courts.

Cardiac channelopathy causing sudden death as revealed by molecular autopsy.

Background: Mutations in cardiac ion channel genes have been identified to cause sudden unexplained deaths (SUD), and polymorphisms have also been suggested to be risk factors. Therefore, postmortem genetic testing has become an important tool in elucidating the cause of death.

Methods And Results: In a sudden death case, a LQT-3-associated mutation (Il768V) in the cardiac sodium channel gene SCN5A was detected beside the common polymorphism H558R which is known to mitigate the effect of mutations in the gene.

Histological validation of DW-MRI tractography in human postmortem tissue.

Despite several previous attempts, histological validation of diffusion-weighted magnetic resonance imaging (DW-MRI)-based tractography as true axonal fiber pathways remains difficult. In the present study, we establish a method to compare histological and tractography data precisely enough for statements on the level of single tractography pathways. To this end, we used carbocyanine dyes to trace connections in human postmortem tissue and aligned them to high-resolution DW-MRI of the same tissue processed within the diffusion tensor imaging (DTI) formalism.

[Relation of external biometric parameters to health risk and mortality--analysis and evaluation of different measurement methods and study results].

In clinical practice diagnoses can be found which are partially based on body measurements. By measuring body height and body weight the patient is categorised, for example by Body-Mass Index (BMI), in different adipose grades. Different diseases are associated with specific biometric parameters.

[Medical and legal aspects of genital mutilation and circumcision. Part II: Male circumcision].

In the last few years, male circumcision has become the subject of controversial discussion. On the one hand, medical and hygienic arguments, ideology, freedom of religion, cultural identity and social adequacy are claimed by those supporting male circumcision. On the other hand, the justification of this practice also has to be critically scrutinized just as the question whether the parents have the right to consent to the operation.

[Medical and legal aspects of genital mutilation and circumcision part I: female genital mutilation (FGM)].

Female genital mutilation (FGM) is considered to be against the law and against morality not only in Western countries, although a woman of age and able to consent may sometimes think differently. The procedure may have serious physical and emotional consequences for the girl or woman. Nevertheless there are attempts to justify the procedure with medical and hygienic pseudoarguments, ideology, freedom of religion, cultural identity and social adequacy.

[Reform of forensic autopsy in the German Code of Criminal Procedure].

The German Federal Ministry of Justice has presented a proposal to amend Section 87 subs. 2 of the German Code of Criminal Procedure (StPO). In the reasons for the bill, the priority of the institutional forensic medicine is emphasized.

Practical experience in post-mortem tissue donation in consideration of the European tissue law.

In consequence of the European guidelines of safety and quality standards for the donation, retrieval, storing and distribution of human tissues and cells the purpose of tissue transplantation was implemented into German legislation in May 2007. The law came into effect on August 1st 2007 considering of the European rules. The Institutes for Legal Medicine of the University of Frankfurt/Main and the University Medical Center Hamburg-Eppendorf developed a model for tissue retrieval.
