Abstract
To research the effect of the COVID-19 pandemic on mental health, the prevalence and characteristics of all completed suicides in the city of Frankfurt am Main were compared for a 10-month period before the pandemic (March 2019-December 2019) with one during the early pandemic (March 2020-December 2020). Medicolegal data collected in the context of the FraPPE suicide prevention project were evaluated using descriptive statistical methods. In total, there were 81 suicides during the early pandemic period, as opposed to 86 in the pre-pandemic period. Though statistically not significant, the proportion of male suicides (73%) was higher during the early pandemic period than before (63%). The age-at-death was comparable in the pre-pandemic and pandemic periods (average, 54.8 vs. 53.1 years). Between these two periods, there was no difference in respect to the three most commonly used suicide methods by men: fall from a height (26% vs. 22%), intoxication, and strangulation (each 24% vs. 19%). For women, there was, however, a shift in methods from strangulation (38%), intoxication (28%), and fall from a height (19%) to fall from a height (50%), strangulation (18%), intoxication, and collision with a rail vehicle (14% each). There was a trend towards more suicides among non-German nationals during the early pandemic (suicide rate/100,000 inhabitants: German, 14.3 vs. 11.5; non-German, 4.4 vs. 8.8). Before the pandemic, 54% of the suicides were known to have a mental illness in contrast to 44% during the early pandemic. Overall, no increase in completed suicides could be observed in Frankfurt am Main during the early pandemic.

Manifestation and staging of arthropathy in cystic fibrosis. Defining different stages of cystic fibrosis arthropathy using ultrasound imaging and clinical scoring. J Cyst Fibros 2023; 22:980-988. [PMID: 37150649 DOI: 10.1016/j.jcf.2023.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Revised: 03/24/2023] [Accepted: 04/17/2023] [Indexed: 05/09/2023]
Abstract
BACKGROUND The true prevalence of cystic fibrosis arthropathy (CFA) remains unclear and may be significantly higher than previously reported. In recent studies, joint symptoms have been reported in up to 30% of adults with CF. This underlines the importance of CFA as a rising and clinically relevant co-morbidity. A clear definition of CFA is yet missing and its pathogenesis remains unclear. We investigated the clinical manifestation of CFA particularly via ultrasound (US) examination to define and implement a staging for clinical assessment. METHODS In a prospective cohort study between March 2018 and February 2020 a total of 98 consecutively recruited, adult cystic fibrosis (CF) patients underwent joint-US examination according to a newly developed ultrasound score (US-CFA). A clinical assessment including rheumatological scores (DAS28, HAQ) has been conducted as well as a specially designed questionnaire. Investigation on clinical and microbiological data, as well as a comprehensive laboratory analysis, were carried out. Cluster analysis has been performed to detect patterns defining different CFA stages based on disease activity. RESULTS US imaging has shown a considerable incidence of mild to moderate effusion as sign of joint inflammation/(teno-)synovitis. K-means clustering was used to distinguish 3 different stages of CFA based on the intensity of the detected effusion. These stages showed a significant association with disease activity (DAS28, p = 0.0004) as well as with patient-reported symptoms such as total weeks of CFA per year (p = 0.004), acute CFA (p = 0.015), chronic CFA (p = 0.016), disease burden (p = 0.04). Based on the US-CFA, 16% of patients suffered from severe CFA (II), 51% from intermediate CFA (I) and 33% did not present detectable arthritis. Positive serology for Chlamydophilia pneumoniae (IgA, IgG) and Chlamydia trachomatis (IgA, IgG) significantly correlated with the US-CFA. CONCLUSIONS The results of this study show that a definition and categorization for the clinical manifestation of CFA can be described through US examination, which is able to detect disease activity concordant with the DAS28 as a validated clinical score on arthritis. Defining these stages will lead to a better understanding of the clinical phenotype of the disease and will optimize diagnosis, therapy and research on CFA in the future.

Complex suicides involving the use of firearms and hanging: A retrospective study and review of the literature. Leg Med (Tokyo) 2023; 69:102337. [PMID: 37926655 DOI: 10.1016/j.legalmed.2023.102337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Revised: 09/03/2023] [Accepted: 10/18/2023] [Indexed: 11/07/2023]
Abstract
INTRODUCTION Suicides are the second most common cause of non-natural death in Germany after accidents. Most common is death by hanging, followed by the use of firearms. More frequent "simple" suicides in which one suicide method is used are distinguished from rare "complex" suicides, in which several methods are applied, whereby the combination of gunshot and strangulation is frequently chosen. Such cases require a thorough criminalistic and forensic medical examination to check the plausibility of assumed sequences of events and to detect covered-up homicides. MATERIAL AND METHODS A retrospective analysis of 5,400 post-mortem examinations at the Institute of Legal Medicine Giessen (2009-2018) revealed three cases in which gunshot and hanging were used to commit a planned complex suicide. RESULTS Case 1: The body of a 66-year-old carcinoma patient was found hanging from a tree in a kneeling position with a bullet through the head. The post-mortem examination revealed a penetrating head shot, uninjured soft tissues of the neck, no injuries to the hyoid bone or larynx and no signs of congestion. After autopsy, the gunshot through the head was considered as cause of death. Case 2: An 82-year-old man was found dead with two bullet wounds in the chest, hanging in free suspension in a factory hall. The necropsy showed two chest entry wounds with injuries to the heart and lungs as well as a vital ligature mark and fractures of the hyoid bone and larynx without signs of congestion. The combination of hanging and the gunshot wounds was concluded as cause of death. Case 3: The body of an 81-year-old pain patient was found in his home next to a small-caliber rifle, with a noose around his neck, attached to a suspension torn from the wall. The autopsy revealed a tangential shot through the skull with superficial injury to the frontal brain and a vital cord mark on the neck with fractures of the hyoid bone and larynx without signs of strangulation. In this case, hanging was identified as cause of death. CONCLUSION Complex suicides are rare events, that require a thorough criminalistic and forensic medical examination Although being called complex suicides and one of the methods usually being suitable to cause death, the cause of death is not always a combined one.

How to prove neglect in the context of the post-mortem examination. Forensic Sci Med Pathol 2023:10.1007/s12024-023-00695-2. [PMID: 37578627 DOI: 10.1007/s12024-023-00695-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/03/2023] [Indexed: 08/15/2023]
Abstract
Understanding the causes, extent, and period of neglect is not only a medical but also a forensic task when it comes to legal investigations. In this study, we evaluated 46 autopsied cases where there was clear evidence of physical neglect during the last period of the deceased's life. The age of the deceased ranged from 21 to 96 years; most of them were female (71.7%). The majority of cases (89.9%) took place in a domestic environment, with partners or relatives providing care. The most frequent post-mortem findings were pressure sores, followed by inflammatory skin changes, and signs of malnutrition and dehydration. Neglect was the cause or co-cause of death in 23% of the cases. More than half of the deceased showed severe contamination of the skin surface by excrement, and in almost 40% of the cases, fly infestation was found. The majority of insects belonged to the group of house flies (Diptera: Muscidae), mainly the common house fly, Musca domestica. By analyzing the entomological evidence, it was possible to prove an insect infestation period of at least several days ante-mortem. Since the period of neglect may be relevant in terms of legal proceedings, the present work demonstrates the particular importance of insect traces in providing this evidence. While prosecution and conviction of caregivers remain challenging, it is all the more essential that entomology and legal medicine collaborate on the analysis of findings of neglect.

Bone finds and their medicolegal examination: a study from Hesse, Germany. Forensic Sci Med Pathol 2023:10.1007/s12024-023-00599-1. [PMID: 37067670 DOI: 10.1007/s12024-023-00599-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/17/2023] [Indexed: 04/18/2023]
Abstract
Bones found by chance can be of great criminal or historical interest. The nature of their appraisal depends on the individual case, the locally effective legislation and the available resources. To assess whether a find is relevant with respect to criminal investigation, the circumstances of the find and the results of the forensic examination carried out by trained personnel must be considered. The aim of this study was to obtain an overview of the circumstances and nature of the finds as well as the results of the subsequent expert opinions by evaluating bone finds from the federal state of Hesse, Germany. For this purpose, over a 10-year period from 2011 to 2020, all bone finds examined at the Institutes of Legal Medicine in Gießen and Frankfurt am Main, Germany, were evaluated retrospectively with regard to the locations and circumstances of the finds, their nature (human or non-human), the postmortem interval, possible traces of violent impact and the results of further examinations. Of the 288 bone finds evaluated, 38.2% were found in forests, meadows and parks. In 50.7%, the finds contained human bones, of which 37.0% had a forensically relevant postmortem interval of 50 years or less. Evidence of trauma was described in 77.4% of the human bone cases: postmortem damage in 78.8%, peri-mortem injury in 9.7% and ante-mortem injury in 11.5%. DNA examinations were performed in 40.4% of the human bone finds. They yielded STR profiles in 81.3%, leading to a definite identification in 35.4%. Among the non-human bones sent in, the most common were bones from pigs (23.4%), deer (18.1%), cattle (16.4%), roe deer (11.7%) and sheep (11.7%). The macroscopic examination is the first step of the forensic-osteological evaluation and sets the course for further examinations or investigations. DNA examinations are of great importance for the reliable identification of human bones. They were responsible for 70.8% of successful identifications.

Abstract
Zusammenfassung
Hintergrund
Der Kalmenhof wurde 1888 vom „Verein für die Idiotenanstalt zu Idstein“ gegründet. Während der NS-Zeit wurden in der „Kinderfachabteilung“ hunderte Kinder und Jugendliche von Ärzten und Pflegern getötet.
Material und Methoden
Nachdem ein historisches Gutachten und Georadaruntersuchungen Hinweise auf Gräber außerhalb einer als Kriegsgräberstätte ausgewiesenen Fläche erbrachte, erfolgten im Sommer 2020 Grabungen.
Ergebnisse
Außerhalb der Kriegsgräberstätte fanden sich keine Gräber. Innerhalb des Areals wurde eine Mehrfachbestattung von drei Individuen in einer 160 × 65 cm großen Grube entdeckt. Die knöchernen Überreste wurden exhumiert und makroskopisch, radiologisch, toxikologisch und molekulargenetisch untersucht. Zwei Individuen waren männlich, das Sterbealter betrug etwa 2,0 bis 2,25 Jahre und 2,5 Jahre. Das dritte Individuum war eine Jugendliche, die Untersuchungen ihrer sterblichen Überreste erbrachten Hinweise auf wiederholte und längere Zeit bestehende Phasen mit unzureichender Nährstoffversorgung. An keinem der Individuen fanden sich Zeichen einer körperlichen Behinderung, prä- oder perimortale Verletzungen. Die toxikologischen Untersuchungen verliefen für alle Individuen negativ. Für die beiden kindlichen Skelette konnte ein vollständiges STR-Profil erstellt werden, an dem jugendlichen Skelett gelang lediglich eine Geschlechtsbestimmung.
Diskussion
Die Ergebnisse stützen historische Angaben, wonach Gräber mehrfach belegt wurden. Demgegenüber war eine Unterteilung des Friedhofes nach dem Sterbealter nicht nachvollziehbar, ebenso wenig, dass sich auf angrenzenden Grundstücken Gräber befinden. Durch die gewonnenen Erkenntnisse wurde ein konkreter Identitätsverdacht für die drei Individuen erarbeitet. Die knöchernen Überreste wurden am Volkstrauertag 2020 im Rahmen einer Gedenkveranstaltung wieder beigesetzt.

Detection and infectivity of SARS-CoV-2 in exhumated corpses. Int J Legal Med 2021; 135:2531-2536.

Abstract
Postmortem detection of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) after the exhumation of a corpse can become important, e.g. in the case of subsequent medical malpractice allegations. To date, data on possible detection periods [e.g. by reverse transcription polymerase chain reaction (RT-PCR)] or on the potential infectivity of the virus after an exhumation are rare. In the present study, these parameters were examined in two cases with a time span of approximately 4 months between day of death and exhumation. Using SARS-CoV-2 RT-PCR on swabs of both lungs and the oropharynx detection was possible with cycle threshold (Ct) values of about 30 despite signs of beginning decay. RT-PCR testing of perioral and perinasal swabs and swabs collected from the inside of the body bag, taken to estimate the risk of infection of those involved in the exhumation, was negative. Cell culture-based infectivity testing was negative for both, lung and oropharyngeal swabs. In one case, RT-PCR testing at the day of death of an oropharyngeal swab showed almost identical Ct values as postmortem testing of an oropharyngeal swab, impressively demonstrating the stability of viral RNA in the intact corpse. However, favorable climatic conditions in the grave have to be taken into account, as it was wintertime with constant low temperatures. Nevertheless, it was possible to demonstrate successful postmortem detection of SARS-CoV-2 infection following exhumation even after months in an earth grave.

Abstract
BACKGROUND Epidemiology and potential risk factors for cystic fibrosis arthropathy (CFA) were studied in a relevant cystic fibrosis (CF) patient cohort. METHODS Cohort study of patients included in the German CF registry in 2016-2017. Descriptive analysis, exploratory tests and multivariable logistic regression were used to assess prevalence of CFA and associated potential risk factors for adult patients with/without chronic Pseudomonas aeruginosa infection. RESULTS 6069 CF patients aged from 0 to 78 years were analysed. CFA was observed in 4.9% of the patients. Prevalence was significantly higher in adult patients (8.4%) compared to patients <18 years (0.7%; p<0.0001). Logistic regression analyses in adult patients (n=3319) showed that CFA was significantly associated with increasing age (OR=1.04; 95% CI: 1.02-1.05; p<0.0001), female gender (OR=2.10; 95%CI:1.52-2.90; p<0.0001), number of hospitalizations (OR=1.24; 95%CI:1.12-1.36; p<0.0001), chronic P. aeruginosa infection (OR=1.83; 95%CI:1.28-2.61; p=0.0009), CF-related diabetes (OR=1.69; 95%CI:1.23-2.33; p=0.0013), pancreatic insufficiency (OR=2.39; 95%CI:1.28-4.46; p=0.0060) and sinusitis/polyps (OR=1.91; 95%CI:1.39-2.62; p<0.0001). In a subgroup analysis of adults without chronic P. aeruginosa infection (n=1550) CFA was also significantly associated with increasing age, female gender, increasing number of hospitalizations, pancreatic insufficiency as well as sinusitis/polyps; antimycotic treatment associated only in this subgroup while association with CF-related diabetes was not significant. CONCLUSION CFA is a frequent and clinically relevant co-morbidity particularly in adult CF patients. CFA is significantly more common in patients with chronic P. aeruginosa colonization but associations with other indicators for a more severe disease course were identified regardless of P. aeruginosa colonization status.

Abstract
Zusammenfassung
Hintergrund
In Frankfurt am Main (~750.000 Einwohner) wird die erste Leichenschau im Auftrag der Polizei tagsüber durch einen dafür eingerichteten rechtsmedizinischen Dienst vorgenommen. Nachts und am Wochenende führen diese Tätigkeit Ärzte des ärztlichen Bereitschaftsdienstes (ÄBD) der kassenärztlichen Vereinigung durch.
Material und Methoden
Für das Jahr 2019 wurden die im Rahmen dieser ersten Leichenschauen ausgestellten Leichenschauscheine hinsichtlich der attestierten Todesart ausgewertet und die Ergebnisse mit denen einer ggf. im Nachgang durchgeführten Sektion, inklusive Zusatzuntersuchungen, verglichen. Von den Ärzten des ÄBD konnten 461 Leichenschauen in die Auswertung eingeschlossen werden, davon erfolgte in 76 Fällen eine Obduktion. Im Nachgang der 364 rechtsmedizinischen Leichenschauen wurden 78 Obduktionen durchgeführt.
Ergebnisse
Veränderungen in der Todesart nach Sektion ergaben sich für die Leichenschauen des ÄBD in 57, bei den rechtsmedizinischen Leichenschauen in 49 Fällen, wobei insbesondere eine bei Leichenschau attestierte ungeklärte Todesart in einen natürlichen Tod spezifiziert werden konnte. Nach der Obduktion fanden sich bei den rechtsmedizinischen Leichenschauen 8 Fälle, bei denen des ÄBD 19 Fälle eines nichtnatürlichen (statt weiterhin ungeklärten) Todes. Bei den rechtsmedizinisch beschauten Fällen änderte sich zudem nach der Sektion in einem Fall die Todesart von natürlich zu nichtnatürlich, bei denen des ÄBD kam es in einem Fall zu einer Änderung von nichtnatürlich zu natürlich.
Diskussion
Die Veränderung bzw. Spezifizierung der Todesart nach der Sektion beider Kollektive verdeutlicht, wie wichtig eine Steigerung der Sektionsrate wäre, und dass auch bei professioneller Durchführung der Leichenschau das Erkennen der Todesart Probleme bereitet.

Abstract
The duration of infectivity of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) in living patients has been demarcated. In contrast, a possible SARS-CoV-2 infectivity of corpses and subsequently its duration under post mortem circumstances remain to be elucidated. The aim of this study was to investigate the infectivity and its duration of deceased COVID-19 (coronavirus disease) patients. Four SARS-CoV-2 infected deceased patients were subjected to medicolegal autopsy. Post mortem intervals (PMI) of 1, 4, 9 and 17 days, respectively, were documented. During autopsy, swabs and organ samples were taken and examined by RT-qPCR (real-time reverse transcription-polymerase chain reaction) for the detection of SARS-CoV-2 ribonucleic acid (RNA). Determination of infectivity was performed by means of virus isolation in cell culture. In two cases, virus isolation was successful for swabs and tissue samples of the respiratory tract (PMI 4 and 17 days). The two infectious cases showed a shorter duration of COVID-19 until death than the two non-infectious cases (2 and 11 days, respectively, compared to > 19 days), which correlates with studies of living patients, in which infectivity could be narrowed to about 6 days before to 12 days after symptom onset. Most notably, infectivity was still present in one of the COVID-19 corpses after a post-mortem interval of 17 days and despite already visible signs of decomposition. To prevent SARS-CoV-2 infections in all professional groups involved in the handling and examination of COVID-19 corpses, adequate personal safety standards (reducing or avoiding aerosol formation and wearing FFP3 [filtering face piece class 3] masks) have to be enforced for routine procedures.

ZusammenfassungBei Suizidformen mit mehreren Suizidenten und Opfern werden teilweise in Literatur und Rechtsprechung eine unterschiedliche Nomenklatur und Interpretation der Begrifflichkeiten vorgenommen. Der Beitrag analysiert die Begrifflichkeiten und befasst sich im Speziellen mit dem Phänomen des Doppelsuizids. Historische Fälle von Doppelsuiziden werden angeführt. Anhand von Fallkonstellationen werden rechtliche Bewertungen vorgenommen, die beim einseitig fehlgeschlagenen Doppelsuizid praxisrelevant werden können. Dabei werden die mitunter konträren Auffassungen in der einschlägigen Literatur und der Rechtsprechung dargestellt und Lösungsansätze aufgezeigt. Zudem verdeutlichen die Fallkonstellationen die Relevanz einer umfassenden Tatortarbeit und einer tatnahen Klärung der Motivationslage bei dem Überlebenden bzw. den Verstorbenen.

Abstract
Zusammenfassung
Hintergrund
Mit dem Masterplan 2020 und den an mehreren Universitäten eingeführten Modellstudiengängen befindet sich das Medizinstudium aktuell im Umbruch. Sowohl im Regel- als auch im Modellstudiengang werden medizinrechtliche Aspekte überwiegend im Rahmen rechtsmedizinischer Ausbildungsabschnitte unterrichtet. Allerdings werden Studierende bereits während Famulaturen oder im praktischen Jahr mit juristischen Fragen konfrontiert.
Ziel der Studie war es herauszufinden, ob und in welchem Umfang Studierende der Humanmedizin insbesondere zur ärztlichen Aufklärung und zu den ärztlichen Informationspflichten bis zum Beginn des 4. bzw. 5. klinischen Semesters auf medizinrechtliche Aspekte vorbereitet wurden, und ob Verbesserungen bei der medizinrechtlichen Lehre gewünscht werden.
Material und Methoden
Zwischen den Sommersemestern 2017 und 2019 wurde zu Beginn des Kurses für Rechtsmedizin eine quantitative, standardisierte Umfrage mit insgesamt 373 Studierenden durchgeführt.
Ergebnisse
Wenngleich 98,8 % der Studierenden angaben, Aufklärungsgespräche bereits (mehrfach) praktisch ausgeübt zu haben, bestanden deutliche Defizite in Bezug auf die juristischen Anforderungen an das ärztliche Aufklärungsgespräch und dessen Delegation. So gaben lediglich 5,1 % der Studierenden an, die rechtlichen Grundlagen der ärztlichen Aufklärung sowie die entsprechende Norm aus dem Zivilrecht zu kennen. Über 80 % der Befragten fühlten sich unzureichend auf die rechtlichen Aspekte des praktischen Jahres vorbereitet. Über 90 % der Studierenden wünschten sich eine bessere medizinrechtliche Ausbildung.
Diskussion
Eine fächerübergreifende Etablierung sowie eine über das gesamte Studium verteilte Lehre von Medizinrecht könnte die Vorbereitung auf das praktische Jahr verbessern und das Verständnis für die rechtlichen Anforderungen an die ärztliche Berufstätigkeit fördern. Nach dem derzeitigen Stand der Umsetzung des Masterplans 2020 soll das Medizinrecht in der Learning Opportunities, Objectives and Outcomes Platform (LOOOP) als verbindlicher Ausbildungs- und Lehrinhalt etabliert werden.

Death abroad: Medico-legal autopsy results of repatriated corpses: A retrospective analysis of cases at the Department of Legal Medicine in Frankfurt am Main. Forensic Sci Int 2020; 310:110257.

Abstract
INTRODUCTION Repatriated corpses may have been autopsied abroad. The aim of the study was to compare the findings from second medico-legal autopsies with those from primary autopsies abroad to spotlight possible implications for the management of repatriated corpses. MATERIAL AND METHODS All autopsies from a 20-year period at the Institute of Legal Medicine in Frankfurt am Main on repatriated corpses of German citizens were reviewed. The results were compared with the information from the body passports, the protocols of the autopsies in the country of death, and the police files. RESULTS In total, 151 corpses repatriated from 56 different countries were autopsied. The interval between death and autopsy in Germany was 2-603 days (median: 11 days). 91 of the repatriated corpses (59.5%) had previously been autopsied abroad. Three body cavities had been opened in 78.0% (71/91) of the original autopsies; among them, there were 11 cases (15.5%) with dissection of all organs, as opposed to 7 cases (9.9%) with all organs intact and in situ. Of the previously autopsied corpses, 62.6% were accompanied by a body passport that noted the cause of death. In nearly 75% of these cases, the stated cause of death was compatible with that established at second autopsy. In 5 cases (10.2%), the cause of death established in the second autopsy disagreed with that on the body passport. The most prominent disparity was a cranial gunshot wound rather than the stated fatal fall. DISCUSSION This analysis of individual cases spotlights the problematics of an uncritical approval of the body passport. In light of the different procedural autopsy standards around the world, the validity of an autopsy abroad is discussed in the context of the second autopsy results. CONCLUSION A second external postmortem examination by qualified medical practitioners should be obligatory in all cases of repatriated corpses, with notification of the criminal police in all cases of non-natural or undetermined death. A timely second autopsy is recommended even in cases with previous autopsy abroad.

Trisomy 21 in forensic autopsies: Review of a 20-year period. Forensic Sci Int 2019; 297:302-306. [PMID: 30852413 DOI: 10.1016/j.forsciint.2019.02.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2018] [Revised: 01/27/2019] [Accepted: 02/12/2019] [Indexed: 11/17/2022]
Abstract
BACKGROUND Trisomy 21 is the most common human chromosomal abnormality. Its manifestation includes intellectual impairment and more or less typical anatomical malformations and functional deficiencies that can cause sudden or unexpected deaths. Typical medicolegal questions at autopsy are related to medical malpractice, improper care, neglect, or abuse, and, depending on the cause of death, whether the death might have been avoidable. The aim of this study was to examine whether the causes of death in individuals with trisomy 21 were linked to the known health risks for this condition and to consider how these deaths might have been prevented. MATERIAL AND METHODS A retrospective study was performed at the Institutes for Legal Medicine in Giessen and Frankfurt am Main, Hesse, Germany. All records for forensic autopsy cases within a 20-year period from 1998 to 2017 were reviewed for the diagnosis trisomy 21", respectively, "Down's syndrome". RESULTS Twenty-three cases complied with the inclusion criteria trisomy 21 and autopsy. The age of the deceased ranged from 23 days to 61 years. Infectious diseases, mainly respiratory, were the leading cause of death, followed by accidental deaths. CONCLUSION The medicolegal relevance of the known health risks in Down's syndrome could be illustrated by the autopsy findings and the results of the additional examinations. The known high susceptibility to infections, with an increased risk of a rapid course and lethal outcome, in individuals with Down's syndrome could be confirmed in our study. A sound knowledge of the risks and abnormalities associated with trisomy 21 are helpful in medicolegal assessments, particularly, in relation to medical malpractice charges.

Beneath cover-up tattoos: possibilities and limitations of various photographic techniques. Int J Legal Med 2019; 134:697-701.

Abstract
BACKGROUND The goal of this study was to investigate the usefulness of various photographic techniques in visualizing previous tattoos under cover-up tattoos. MATERIAL AND METHODS Ten volunteers with 11 known cover-up tattoos were examined using different photographic techniques: A Canon EOS 6D full-frame digital single-lens reflex camera used in conjunction with a SB600 off-camera flash system and an extension cord; and a Leica M8 digital imaging system camera in conjunction with two different infrared filters (715 nm and 850 nm) and a Metz CL-45 handle-mount flash. A Lumatec Superlite 400 forensic light source was used along with the Canon EOS 6D as a third system. RESULTS The best results for black cover-up tattoos were achieved with the full-frame digital single-lens reflex camera in conjunction with the off-camera flash system and, for colored cover-up tattoos, with IR-photography at a wavelength of 850 nm. The Lumatec Superlite 400 light source did not provide better results for conventional photography than those obtained with flash lighting. DISCUSSION In nine out of eleven cover-up tattoos, the previous tattoos could, at least, be partially visualized. The quality of the visualization depended on the color, pattern, density, and quality of the cover-up tattoo as well as on the photographic technique. None of the examined photographic techniques could satisfactorily image the previous tattoo if the cover-up tattoo was large and black, especially not if it was densely inked. CONCLUSION Depending on the color of the cover-up tattoo, a full-frame digital single-lens reflex camera in conjunction with a SB600 off-camera flash system (for black cover-ups) or infrared photography with flash lighting and an 850 nm filter (for colored cover-ups) proved to be the best of the investigated techniques to visualize a previous tattoo under a cover-up tattoo.

Abstract
ZusammenfassungAdaptive Optiken (AO) stellen eine technologische Schlüsselinnovation für die Bildgebung in der Ophthalmologie dar. Mit AO ausgestattete Ophthalmoskope erlauben es, die mikroskopische Netzhautstruktur nicht invasiv und auf zellulärer Ebene darzustellen. So kann die strukturelle Integrität der retinalen Nervenfaserschicht, des perifovealen Kapillarnetzwerks, einzelner Stäbchen- und Zapfenphotorezeptoren und des zellulären Mosaiks des retinalen Pigmentepithels in vivo beobachtet werden. Für die Beurteilung des Verlaufs von Netzhauterkrankungen, einer möglichen pharmakologischen Intervention und die Entschlüsselung der zugrunde liegenden physiologischen Mechanismen bedeutet dies eine völlig neue Untersuchungsebene. Insbesondere monogenetische Erkrankungen liegen im Fokus der aktuellen Forschung. Zum einen können Rückschlüsse auf einzelne Pathologien anderer multifaktorieller Netzhauterkrankungen gezogen und so die zugrundeliegenden physiologischen Mechanismen bzw. Verläufe genauer untersucht werden (Modellerkrankung). Zum anderen werden auch im Hinblick auf aktuelle und kommende Interventionen (u. a. Gentherapie) neuartige und zuverlässige Endpunkte zur Interpretation des Therapieerfolgs notwendig. Erste kommerzielle AO-Ophthalmoskope sind für den klinischen Einsatz erhältlich, und die Zahl mit AO untersuchter Netzhautpathologien wächst zunehmend. Für eine zellgenaue Struktur-Funktions-Korrelation kann jüngstens eine AO-basierte Mikrostimulationstechnologie eingesetzt werden.

Abstract
This retrospective study evaluated the results of plating versus intramedullary fixation in the management of unstable, diaphyseal fractures of both bones of the forearm in children. Of the 64 children included, 45 were treated with intramedullary fixation, 19 with plating. Only A3 forearm fractures of the middle third or the transition zones were included; Galeazzi, Monteggia, and Greenstick fractures were excluded. Full radiological follow-up to union was obtained in all cases and 60 patients returned for clinical evaluation 32.3 months (plating) and 20.6 months (intramedullary fixation) after injury. The functional outcome did not differ significantly. In the intramedullary fixation group, we found two major complications (refracture and non-union) and nine minor complications (two delayed unions, three thumb neuropathies, two rod migrations, two skin infections). In the plate group, there were two major complications (refractures) and one minor complication (thumb neuropathy). Plating resulted in significantly worse results for surgical approach, operating times, frequency and duration of hospitalisation, and cosmetic outcome. In conclusion, intramedullary fixation of an unstable forearm fracture in skeletally immature patients is a safe, child-friendly, minimally invasive technique that allows early functional treatment with an excellent functional and cosmetic outcome.

Abstract
BACKGROUND Until recently, only two options were available for the treatment of choroidal neovascularization (CNV) due to age-related macular degeneration (AMD): laser photocoagulation and photodynamic therapy (PDT) with verteporfin. However, potential new treatments for CNV are under development, and data from phase III clinical trials are now available. Referring to these data, expert guidance is required to supply ophthalmologists with expertise in the management of AMD to select and use the most appropriate therapies in the treatment of neovascular AMD. METHODS The therapeutic modalities discussed include thermal laser photocoagulation, PDT with verteporfin, triamcinolone acetonide and the possible combination with PDT, anecortave acetate, pegaptanib sodium and ranibizumab. After a short description of the treatment principles, a summary of the discussion of all relevant study results of the different treatment options with respect to the different subtypes of neovascular AMD is presented. These discussions resulted in an "up-to-date" recommendation of therapeutical strategies in neovascular AMD. RESULTS For subfoveal lesions with predominantly classic CNV, or with occult with non-classic CNV and a lesion size < or = 4 macular photocoagulation study (MPS) disc areas (DA), PDT with verteporfin is recommended; for subfoveal lesions with minimally classic CNV, treatment with PDT or pegaptanib sodium is possible, even if there are some problems with the statistics in the studies with both treatment modalities. PDT with verteporfin should be considered for juxtafoveal lesions that are so close to the fovea that laser photocoagulation would almost certainly extend under the center of the foveal avascular zone, and for all other juxtafoveal lesions and for extrafoveal lesions laser photocoagulation is suggested. Therapy should be performed not later than one week after the initial fluorescein angiogram upon which the clinical decision for treatment is based. At each follow-up best-corrected visual acuity and a fundus examination should be performed as well as a fluorescein angiography every three months. CONCLUSIONS These recommendations provide good clinical guidance for the choice and use of laser and pharmacotherapies for the management of CNV due to AMD. Revisions of the recommendations will be required as new data become available.

Abstract
The purpose of this work was to develop and evaluate a psychosocial intervention aimed to improve quality of life of AMD patients. A total of 22 outpatients (age 62 to 80 years) treated in the University Eye Clinic in Heidelberg were divided into an intervention group (n=14) and a comparison group without intervention (n=8). The intervention program was based on six modules carried out in five weekly group sessions. These modules included: (1) progressive muscle relaxation, (2) exchange of disease-related experiences, (3) connection between thought, emotion, and behavior, (4) activation of available resources, (5) general problem solving skills and (6) information exchange. Pre-post assessment addressed a set of standardized emotional and behavioral outcome measures. Findings revealed that the intervention group showed improvement or prevention of additional loss in emotional as well as in behavioral outcomes, while the comparison group did not. Results are interpreted as initial evidence that the developed program is able to improve the quality of life in patients suffering from AMD.

Abstract
Injuries of the posterior pelvic with combined anterior and posterior instability require the stabilisation of both the anterior and posterior pelvic ring. If the injury only involves the ligamental connections, then a transileosacral osteosynthesis with screws is the minimal invasive and biomechanically suitable method of choice. The difficulty with this approach is the correct placement of the screws. Their position must be monitored intraoperatively in 3 planes (inlet, outlet and lateral viewing). This denotes that conventional methods involve high radiation dosages for the patient and the surgical staff. Having the system readily available and being able to perform updates during the operation, fluoroscopically supported navigation for the treatment of fresh injuries becomes possible. Between October 1999 and December 2000 7 patients with traumatic instability of the posterior pelvic ring were treated by computer assisted percutaneous transileosacral screw osteosynthesis. In each case the osteosynthesis of the ileosacral joint was performed with two cannulated AO 7.3 mm titanium screws. After the operation the screw position was controlled by CT scanning and compared to the data acquired intraoperatively. No patients had infection, and there were no postoperative neurological defects. The postoperative CT scans showed no intraspinal or intraforminal malplacement of the screws. In two cases a slight tangential screwthread penetration through the ventral sacrum was found. Our first experiences with this novel technology are encouraging and clearly demonstrate the advantages of fluoroscopic supported passive navigation systems for the optimal placement of ileosacral screws.

Abstract
UNLABELLED The aim of our study was to develop noninvasive stereotactic radiotherapy for patients with choroidal metastases. METHODS The head of the patient was immobilized by an individual cast mask. The target volume and adjacent critical structures were three-dimensionally segmented based on ophthalmological findings and MRI. The beam angles were optimized by a beam's eye view technique with a micro-multileaf collimator. We use a linear accelerator with 6-MeV photons. A patient was treated in a phase I/II trial with a single dose of 22.5 Gy. RESULTS The accuracy of stereotactic positioning of the eye was 0.8 mm. The dose gradients were 15% mm. It was possible to spare the lens and the lacrimal gland in all cases. The treatment with four to six fields took 35-50 min and was tolerated without acute complications. CONCLUSIONS We introduce a new method to treat choroid metastases by stereotactic radiotherapy. This method allows to concentrate the dose to the target and to spare adjacent critical structures. One of the advantages of this noninvasive treatment is the short treatment time. The clinical role of this method has to be evaluated based on long-term results of tumor control and visual outcome in these patients.

Abstract
After a car accident, a 19-year-old man had to undergo laparotomy in a local hospital due to intra-abdominal bleeding. A right-sided transrectal incision was chosen, and to improve exposure the rectus muscle was cut horizontally at the cranial end of the incision. Ten days after the accident the patient was transferred to our hospital for stabilization of the pelvic and acetabular fracture on the right side. An ilioinguinal approach was chosen. Two days later the abdominal cavity was opened due to necrosis of the cranial part of the rectus abdominis muscle. Following a 10-day period without pathological symptoms, suddenly sepsis developed. Ultrasound showed a lot of fluid in the rectus sheath; no muscle structure could be identified. The operation showed total necrosis of the rectus muscle due to thrombotic occlusion of the inferior epigastric artery. The standardized tourniquets around the vessels used during the ilioinguinal approach seemed to be responsible for the rectus muscle necrosis. Therefore, if a combined intraabdominal and pelvic approach has to be used, median laparotomy is the better choice, because no risk is posed to the blood supply of the rectus muscle, in contrast to the ilioinguinal approach. The problem is discussed in detail.

Abstract
The subject of this report is an automated photometric method for the determination of the content of total niacin in grain and cereal food. The customary coupling reagent sulfanilic acid has been replaced by 1,3-dimethylbarbituric acid; CNCl is produced in the flow through system directly from KCN and chloramine T. The composition of reagents, the procedure and the analytical manifold are specified. 30 analyses/h can be performed. The accuracy and reproducibility of the automated method is good. In a range of 0.5-4.0 micrograms/ml niacin and a total content of 10-135 mg niacin/kg dry matter an average variation coefficient of vk = 0.74% (n = 10) was obtained. When lack of homogeneity of samples and variation in alkaline hydrolysis are included average vk to +/- 2.43% at the same range of niacin. The content of total niacin in various kinds of grain and in enriched ready to eat cereal foods was determined.

Abstract
Previous experimental results have demonstrated the possibility of eliminating imipramine (14 C-IP) by hemodialysis. A simultaneous uptake of the substance by the polyvinyl chloride extracorporeal blood lines could be shown. Based on these results the imipramine absorption capacity of the blood lines and of the artificial kidney (Hollow Fiber Artificial Kidney, HFAK, Model 4) were studied. Imipramine (IP) absorption capacity of a usual blood-line set (arterial and venous, surface area 86,000 mm) was estimated to be 43 mg, and that of the HFAK to be 207 mg. Charcoal hemoperfusion (300 gm of coated activated coconut charcoal) eliminated more than 90% of IP from the blood within 3 hr if the initial IP blood concentration was 2 mg/ml. In comparison, lipid hemodialysis using 20% soybean oil as dialysate eliminated 95% of IP from the blood when the initial IP blood concentration was 1 mg/ml and 98% when the initial IP blood concentration was 2 mg/ml. In vivo studies on the elimination of IP by lipid (10%) hemodialysis demonstrated a substantial removal of the substance. Within 2 hr of treatment, 12% of the administered dose (75% of the LD50) was eliminated.

Abstract
In the last several years an increasing number of severe imipramine intoxications have been observed. Though standard principles for the treatment of acute tricyclic poisoning have been established, nonetheless there still exists doubt on the most effective method of tricyclic removal in cases of massive overdose. Haemodialysis was successfully employed until now but has not found general acceptance as only insignificant amounts of imipramine could be recovered from the dialysate. An experimental clearance study was undertaken using radiolabelled imipramine (14C-I) to obtain insight into the usefullness of haemodialysis in imipramine poisoning. 14C-I clearances which were calculated in a closed circuit dialysis system ranged between 18 ml/min and 48 ml/min depending on the constitution of the dialysate, i.e. aqueous or lipid solution. Surprisingly a rapid and significant uptake of imipramine by the plastic material (polyvinylchloride) of the extracorporeal blood line system was detected. This escape of imipramine from the blood into the tubings explains the poor recovery of tricyclics from the dialysate, which discredited haemodialysis as a therapeutical method in imipramine poisoning. The results of our experiments may offer a new method of rapid tricyclic elimination in severe imipramine intoxications.
