From Deutsche Zeitschrift to International journal of legal medicine-100 years of legal medicine through the lens of journal articles, Part 4: International journal of legal medicine from 1990 to 2022.

This is the fourth and final paper in a series related to the analysis of articles published in this journal during its first 100 years of activity. This article covers the time span from 1990 to 2022. It is important to note that, given the period covered by this analysis, it does not aim to provide a historical overview but rather an examination of the most recent trends in our discipline compared to the past.

From Deutsche Zeitschrift to International Journal of Legal Medicine-100 years of legal medicine through the lens of journal articles : Part 3: Zeitschrift für Rechtsmedizin-Journal of Legal Medicine from 1970 to 1990.

From volume 67 (1970) onwards, the journal appeared under the new bilingual title Zeitschrift für Rechtsmedizin-Journal of Legal Medicine. The editorial board was expanded and internationalised. From 1970 to 1990, 1416 articles were published in 36 volumes.

From Deutsche Zeitschrift to International Journal of Legal Medicine-100 years of legal medicine through the lens of journal articles : Part 2: Deutsche Zeitschrift für die gesamte gerichtliche Medizin from 1948 to 1969.

The interruption of the publication of the Deutsche Zeitschrift für die gesamte gerichtliche Medizin due to the war ended with volume 39 for the years 1948/1949. Until volume 66/1969, the journal appeared unchanged under the historical title. The 912 publications contained in the 28 volumes of these two decades cover topics from the main fields of forensic medicine, but also from related and unrelated disciplines.

From Deutsche Zeitschrift to International Journal of Legal Medicine-100 years of legal medicine through the lens of journal articles : Part 1: Deutsche Zeitschrift für die gesamte gerichtliche Medizin from 1922 to 1944.

From its launc h in 1922 to the end of the Second World War, the Deutsche Zeitschrift für die gesamte gerichtliche Medizin spanned 38 volumes. The 1762 papers contained in those volumes reflect contemporary interests and include many papers from peripheral fields and non-medico-legal disciplines. Publications concerned with issues outside core legal medicine fields in particular allow two distinct tendencies in the development of German institutes of legal medicine to be discerned.

[A literature review on the Messerer's fracture].

The characteristic wedge-shaped fracture was first described by Messerer (1880) and Bruns (1884) after performing experiments on long bones. Not much later, Messerer (1885) formulated the forensic significance of the direct bending fracture for the detection of the location and direction of blunt impact trauma. He developed the basic biomechanical theory of the origin of this fracture type, which is therefore called Messerer's fracture in the German-speaking world.

[Walcher's hat brim line rule--a literature review].

The first description in the forensic medical literature of a demarcation line for the localization of head injuries resulting from falling to the ground appears in Kratter (1919). Regarding a similar line, Walcher (1931) later introduced the relation to the hat brim (Hutkrempe), which gave the rule its name: the hat brim line rule (Hutkrempenregel). Thenceforth it was supposed to be called Kratter's and Walcher's hat brim line rule (Kratter-Walcher'sche Hutkrempenregel).

[About the Geserick sign--a literature study].

Fractures of the medial and basal orbital wall as well as the petrous part of the temporal bone were described first in 1980 by a Berlin-based study group led by Geserick as new cranium findings resulting from a contrecoup mechanism. Experimental and comparative examinations revealed that indirect fractures of the orbital walls are caused by a coup action of the eyeballs, whereas the mechanogenesis of the petrous bone fractures continues to be unclear. The frequently combined occurrence with the orbital sign nonetheless permits an allocation to the contrecoup mechanism.

[History, present situation and perspectives of forensic age diagnostics of living persons].

Although age estimations of living persons have been carried out for a long time already, the importance of forensic age diagnostics has increased considerably since the beginning of the 1980s. The Study Group on Forensic Age Diagnostics of the German Society of Legal Medicine founded under the chairmanship of Prof. Dr.

Genetic Kinship Investigation from Blood Groups to DNA Markers.

The forensic application of hereditary characteristics became possible after the discovery of human blood groups by Karl Landsteiner in 1901. The foundation for their use in kinship investigation was laid by Emil von Dungern and Ludwig Hirschfeld in 1910 by clarification of the inheritance of the ABO groups. Up to the middle of the 20th century further red cell membrane systems were discovered.

[Puppe's rule--a literature review].

As early as 1903, it was pointed out by Puppe that it is possible to determine the sequence of injuries in skull fractures caused by blows to the head: the second fracture ends at the point where a break in cohesion is already present. This finding was confirmed by tests carried out by other forensic pathologists. It soon became clear that the rule also applies to gunshot fractures.

[Negligent homicide caused by exhaust gas escaping from a manipulated chimney].

A chimney built and operated according to the instructions is supposed to ensure that the combustion gases coming from the fireplace can escape safely. If the operational reliability is impaired, this presents a risk of acute poisoning. The report deals with a negligently caused carbon monoxide poisoning of a married couple as a consequence of improper installation of a cover of the chimney opening.

[The Berlin morgue of 1886--the 125-year-old morgue of Berlin-Mitte].

On 1 March 1886, a new morgue built along the lines of the Paris morgue, was opened in Berlin, Germany. Experts from many European countries were interested in the new building with its modern design and equipment. As the morgue, the Institute of Legal Medicine of the Berlin University accommodated in the same building also acquired international reputation.

[Tardieu's spots and asphyxia--a literature study].

Subpleural, epicardial and pericranial ecchymoses have been described in cases of suffocation since the 18th century. In the 19th century, great diagnostic importance was attributed to ecchymoses. Tardieu was the most determined defender of the specificity of ecchymoses for suffocations.

Surface biofunctionalization and production of miniaturized sensor structures using aerosol printing technologies.

The work described in this paper demonstrates that very small protein and DNA structures can be applied to various substrates without denaturation using aerosol printing technology. This technology allows high-resolution deposition of various nanoscaled metal and biological suspensions. Before printing, metal and biological suspensions were formulated and then nebulized to form an aerosol which is aerodynamically focused on the printing module of the system in order to achieve precise structuring of the nanoscale material on a substrate.

[Medicolegal identification of victims in mass disasters using the example of aircraft accidents].

In mass disasters, the main task of the medicolegal expert is to support the victims' identification. As such events are rare, the knowledge obtained during previous operations should be evaluated and published to improve the quality and effectiveness of the identification work in future disasters. This report describes the experience gained at the Institute of Forensic Medicine of the Humboldt University in Berlin during the identification of the victims of three aircraft accidents (1972, 1986, 1989).

[Medico-legal autopsies in Berlin from 1999 to 2003].

This paper presents statistical data on medico-legal autopsies at the three Berlin institutes from 1999 to 2003. With an autopsy frequency of 6.5% in 1999, Berlin was ranking at the top in Germany.

[Werkgartner's muzzle imprint mark--a literature study].

Since Werkgartner described and correctly interpreted the muzzle imprint mark around the gunshot entrance wound in 1922, this finding has been generally accepted as a sign of a contact shot. In further studies, it could finally be clarified that the muzzle imprint mark is caused by the expansive power of the powder gases with pressure on and abrasion of the skin at the muzzle (weapon imprint). Its shape depends on the firearm, the ammunition and the anatomical conditions, but does not require a bullet.

Unassisted smothering in a pillow.

We report the case of a 33-year-old man admitted to a psychiatric hospital because of paranoid schizophrenia. The man was found dead lying in his bed with the face pressed against a pillow and with elevated buttocks. The autopsy did not reveal a cause of death.

[Medico-legal study on crashes of fighter planes of the National People's Army].

In the years 1974 to 1990, 39 pilots died in 34 crashes of fighter planes of the National People's Army; 32 victims were examined forensically. For the present study all autopsy protocols and examination reports available in the German Federal Military Archives in Freiburg could be evaluated. Both officer cadets and experienced pilots of high military ranks were among the victims.

[The University Institute of Legal Medicine in Berlin 1833-2008].

The university institute of legal medicine of the Charité in Berlin was founded on February 11th, 1833 as a "Praktische Unterrichtsanstalt für die Staatsarzneikunde (Practice-oriented School of Public Health and Medicine)" at the Friedrich-Wilhelms-Universität (founded in 1810). In 1886 the oldest faculty in Germany obtained its own building in Berlin-Mitte. Starting with Wilhelm Wagner, Johann Ludwig Casper, Fritz Strassmann, Otto Prokop and their successors established the Berlin School of Legal Medicine, which has been playing an important role for the subject's progress in the German-speaking area until today.

[Death by electric shock due to blatantly faulty repair].

Due to technical innovations and strict safety regulations the rate and mortality of accidents caused by electric current has been considerably reduced. Nevertheless there are still deaths caused by electric shock, which are mostly due to carelessness and ignorance. The described death by electric shock of a 39-year-old man was the consequence of an electrotechnical curiosity.

[Cannibalistically intended homicide following a media report].

Inspired by media reports on the cannibalistically motivated homicide in Rotenburg (German state of Hesse), a man in Berlin with homosexual tendencies decided to realize his longstanding fantasies of slaughtering someone. He killed another homosexual man and dismembered his victim, while the motive changed from an offensive and necrophile to a defensive dismemberment of the body. The parallels between the two homicides are presented and discussed.

[Double homicide by shooting with removal of the victims].

Despite strict assault weapons laws shooting deaths are not uncommon in the Federal Republic of Germany. Especially in multiple one-stage homicides shooting is a frequently established cause of death. The described double homicide from the autopsy material of the Berlin Institute of Legal Medicine shows the difficulties in the forensic assessment of gunshot wounds.
