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. Between 1990 (Volume 104) and 2022 (Volume 136), 4004 articles were published in the International Journal of Legal Medicine (IJLM) across 33 volumes. This corresponds to 53% of all the articles published since the launch of the journal. When compared to the period from 1970 to 1990, some categories no longer appear to be as relevant (e.g., sexual medicine, 1 article; social medicine, 0 articles; biography, 3 articles; history, 4 articles). Conversely, the most recent period has shown an increasing importance in forensic genetics (1388 articles) and the emergence of new significant topics that merit their own classification, such as age estimation (286 articles), forensic anthropology (189 articles), forensic imaging (150 articles), and forensic entomology (90 articles)., (© 2023.

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. 1036 articles were in German and 380 in English. The authors of 411 articles came from non-German-speaking countries. Compared to the periods under review in the first two parts of our article series, the proportion of papers on forensic genetics increased significantly between 1970 and 1990, with a small increase in publications on the identification of unknown dead bodies. An opposite trend was observed in the articles on forensic psychiatry and psychology, sexual medicine and social medicine. This development reflects a further sharpening of the discipline's profile., (© 2023. The Author(s).)

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. The topic-specific analysis of the publications shows a shift of the research focus in the German institutes since the post-war period. This is most evident in the decline in the number of publications from the fields of scientific and technical criminalistics as well as forensic psychiatry and psychology. An opposite trend with a significant increase in scientific papers was observed in alcohology, forensic genetics and traffic medicine. While the evaluated publications on most topics contain new findings that are still valid today, the use of blood group characteristics for forensic purposes came to an end as a result of the introduction of DNA analysis., (© 2022.

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. Firstly, there is a focus on the psychological and psychiatric aspects of the discipline. Secondly, there is tendency towards a scientific-criminalistic outlook. The fatal consequences of the Nazi seizure of power in 1933 did not spare the sciences. For legal medicine, a discipline with close links to the state, it is unsurprising that fundamental changes to the political system had a significant impact on subject matter. Leaving aside articles notable principally for their ideological content, our analysis of the 38 volumes shows that the papers examined contain new insights into many subjects, some of which are still valid today., (© 2022.

The diagnosis of drowning is considered one of the most difficult in forensic medicine. Due to the paucity of signs, it is a classical diagnosis by exclusion. For this reason, specific immunohistochemical markers would be useful. Far too little has been done to analyze in-depth the differences between SWD and FWD. We focused on the renal immunohistochemical expression of aquaporin 2, AVP, V2R, and renin in cases of drowning. This study has two purposes: (1) to better understand the differences between saltwater drowning (SWD) and freshwater drowning (FWD), which may indicate different pathophysiology and (2) to eventually identify markers useful for the diagnosis of drowning. We retrospectively investigated 10 cases of SWD gathered from the Institute of Legal Medicine in Genoa (Italy), and 10 cases of FWD from the University Center of Legal Medicine in Geneva (Switzerland). As a control group, we investigated 10 cases of death by gunshot to the head. A strong expression of AQP2 and AVP was significantly (p < 0.05) more evident in cases of SWD than in FWD and control cases. Regarding the V2R, no statistically significant differences were found between the studied groups. The renin tubular expression was particularly intense (p < 0.05) both in SWD and in FWD compared controls. According to our results, AQP2 and AVP represent potential useful markers for the differential diagnosis between SWD and other causes of death, including FWD. Renin may be a useful marker in the diagnosis of drowning but it does not allow for differentiation between FWD and SWD. [ABSTRACT FROM AUTHOR]

The diagnosis of drowning is one of the most difficult in forensic medicine. The aim of this study was to analyze pulmonary tissue reactions in death by drowning. In particular, we focused on the immunohistochemical expression of P-selectin, SP-A, HSP70, AQP-5, and fibronectin to investigate our expression in drowning and to understand whether there are differences between saltwater drowning (SWD) and freshwater drowning (FWD), which may indicate a different pathophysiology. We retrospectively investigated 10 cases of SWD (Mediterranean Sea) from the Institute of Legal Medicine of Genoa (Italy), and 10 cases of FWD (Lake of Geneva) from the University Center of Legal Medicine of Geneva (Switzerland). As control group, we examined 10 cases of death by acute external bleeding, characterized by minimal respiratory distress. As compared with controls, in SWD cases, the results showed a decrease of SP-A expression with membrane patterns. Furthermore, we observed a greater SP-A expression with granular pattern in drowning cases without statistically significant difference between SWD and FWD. For the markers AQP-5, HSP70, fibronectin, and P-selectin, no statistically significant differences were found between SWD, FWD, and controls. [ABSTRACT FROM AUTHOR]

At the end of 2020, together with the IALM Presidium, we decided to convert the Congress in Geneva in an online event only. Graph Virtual Edition June 1 SP st sp to 4 SP th sp , 2021 Publication of this supplement was funded by the 25th Congress of the International Academy of Legal Medicine. To do this, we could count on the active support of the Forensic team of the International Committee of the Red Cross, of the Forensic Anthropology Society of Europe, of numerous colleagues and friends that accepted our invitation to organise the workshops and symposia of this congress.

• A descriptive study of antemortem photographic materials of missing migrants. • The quantity and quality of AM images provided by relatives of missing migrants. • Unavailability of classical AM data for identification of dead migrants. • Images may turn out to be fundamental and sometime the only resort for identification. The crisis concerning the identification of dead migrants is forcing forensic scientists to deal with the unavailability of classical antemortem (AM) data such as radiological information and DNA. However many times there is abundant AM photographic data of which the availability and quality is underestimated. Independently of when facial image comparison can be used as a valid identification method, description of the unexpected quality and quantity of images in the scenario of unidentified migrant decedents is given in this observational study. It focuses on the overall characteristics of the AM images available for a group of 74 missing migrants related to the disaster of October 3rd, 2013. 394 images were collected: an average of 6 for each missing person. 18% are original pictures, 47.5% scans of original images, 9.9% scans of printed images while 9.4% downloaded from social networks such as Facebook. 42.7% of images resulted in focus. Among all the images, about the 10% has been used in the personal identification process to ascertain the identity of 22 persons, because of the visibility of identifying details (facial, dental and body features). The importance of such a finding should not be diminished by its simplicity. Today, those involved in collecting AM information from relatives of dead migrants are underestimating the possible presence of images, even in sub-Saharan populations, where, contrary to belief and data, technology, though simple, is available and images may turn out to be abundant and useful (and at times the only resort) for identification.
