We are deeply concerned about the scientific quality of the article "Asymptomatic Infant Rib Fractures Are Primarily Non-abuse-Related and Should Not Be Used to Assess Physical Child Abuse" published in the journal Children in 2023 by van Gemert et al [...].

Purpose: Subdural collections (SDCs) represent a key finding in abusive head trauma (AHT), a serious form of child physical abuse. Common SDC entities in this context are subdural hematoma (SDH), subdural hygroma (SDHy), subdural hematohygroma (SDHHy), and chronic subdural hematoma (cSDH). The present study examines the prevalence of the different SDC entities and investigates the influence of the SDC diagnosis on the forensic age estimation of the injury., Methods: In this retrospective multi-center study from three German university hospitals of a 10-year period, the initial neuroimaging material (CT or MRI) of 56 children (36 males, 20 females; age median 3.9 months) with medico-legally well-documented AHT was analyzed. SDCs were characterized by determining presence, location, extension, and visual appearance, by assigning to one of the five entities, and by categorizing with three different classification systems, one of which represents a novel system based on focality and Mixed Appearance Pattern and especially developed for children with AHT. The data were correlated with demographic and clinical data. By means of court files, AHT cases were also sub-divided into confession (n = 14) and non-confession cases (n = 42) and then compared., Results: Most cases showed a multifocal presence of SDCs (96.4%) and the presence of a Mixed Appearance Pattern (82.1%). The most common SDC entity was the heterogeneous variant of the SDHHy (66.1%). The cSDH occurred infrequently only (3.6%). Our novel classification system illustrates that unifocal SDCs rarely occur in AHT, and that more complex SDC patterns are common. In nearly all cases (94.6%), additional signs of recently caused brain injury were present beside the SDCs. Comparison between confession and non-confession groups did not reveal any significant differences, indicating that the diagnostic criteria of AHT are robust., Conclusions: Although precise dating of SDCs based on initial neuroimaging alone remains unrealistic, the exact diagnosis of the SDC entity provide an important basis for differentiation between acute trauma and chronic post-traumatic state. Therefore, especially the confirmation or exclusion of subdural neomembranes, that define the cSDH, should be considered indispensable., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

Abusive head trauma (AHT) and its most common variant, the shaken baby syndrome (SBS), are predominantly characterized by central nervous system-associated lesions. Relatively little data are available on the value of skeletal and skin injuries for the diagnosis of SBS or AHT. Thus, the present study retrospectively investigated 72 cases of living children diagnosed with the explicit diagnosis of SBS during medico-legal examinations at three German university institutes of legal medicine. The risk of circular reasoning was reduced by the presence of 15 cases with confession by perpetrators. Accordingly, the comparison with the 57 non-confession cases yielded no significant differences. Skeletal survey by conventional projection radiography, often incomplete, was found to be performed in 78% of the cases only. Fractures were found in 32% of the cases. The skull (43%) and ribs (48%) were affected most frequently; only 8% of the cases showed classic metaphyseal lesions. In 48% of the cases, healing fractures were present. Skin lesions (hematomas and abrasions) were found in 53% of the cases with the face (76%), scalp (26%), and trunk (50%) being the major sites. In 48% of the cases, healing skin lesions were observed. Nearly 80% of the cases with fractures also showed skin lesions. The data prove that SBS is frequently accompanied by other forms of physical abuse. Therefore, skeletal survey is indispensable and should always be done completely and according to existing imaging guidelines if child abuse is suspected., (© 2021. The Author(s).)

Background: Diagnostic imaging plays a key role in the evaluation of non-accidental consequences of injuries in childhood. Fractures are the second most common consequence of child abuse, after skin lesions such as abrasions or bleeding. With the evidence of radiological criteria, non-accidental fractures can be differentiated from accidental fractures. Special types of fractures such as the classic metaphyseal lesion can only be differentiated if the image quality is high., Aim: The goal of this prospective study was to assess adherence to guidelines and quality assurance of radiological diagnostics in the event of suspected abuse in Germany. For this purpose, the quantity and diagnostic quality in university and non-university hospitals as well as the existence of a pediatric radiology department were analyzed., Materials and Methods: In all, 958 X‑ray examinations of 114 suspected abuse cases (46 girls, 68 boys) were evaluated; 42 cases from university, 42 from maximum care and 30 from regular care clinics with a median age of 6 months (3 weeks-3 years of age) were assessed as DICOM data by 3 pediatric radiologists in a consensus procedure with regard to adherence to guidelines and various quality parameters. An accompanying questionnaire was used to compare the theoretical knowledge with the respective practical implementation., Results: A mean of 8.4 X‑rays (range 1-22) were made per case. In 12 of 114 assessed cases (10%) there was a complete skeletal status according to the S1 guideline. A babygram was performed in 13 cases (10.5%). Departments with focus on pediatric radiology produced significantly more X‑rays per skeletal status than facilities without this specialization (p < 0.04). Significantly higher qualitative implementation was recorded in university hospitals (p < 0.001). Regardless of the type of institution, there was only marginal agreement between the questionnaire response and the available image material., Conclusion: In Germany, a guideline-compliant procedure in the event of suspected child abuse is largely lacking. It remains to be seen whether this will change in the future with the broader implementation of child protection groups and the S3+ child protection guideline adopted in 2019 (AWMF register 027-069). The establishment of reference centers for a second diagnosis and recommendations for imaging technology can also improve the quality of care over the long term., (© 2021. The Author(s).)

The shaken baby syndrome (SBS) is a common variant of abusive head trauma (AHT) in infants and toddlers. Data on the legal outcome of such cases are still sparse. By means of a retrospective multi-center analysis, 72 cases of living children diagnosed with SBS/AHT from three German university institutes of legal medicine were identified. Forty-six of these cases with 68 accused individuals were available and could be evaluated with regard to basic data on the course of the criminal proceedings as well as the profile of the defendants (sub-divided into suspects, convicts, and confessed perpetrators). Criminal proceedings predominantly commenced with a complaint by the treating hospital (62%) and were found to be closed (without judgment) in 50% of the cases, mostly due to a "lack of sufficient suspicion." Of the 23 cases with judgment, the court decided on acquittal in 4 cases (17%). Imprisonment was the most frequent sentence (16 out of 19 cases with conviction, 84%), whereby the sentence has been suspended on probation in 63% of the cases. Suspects and perpetrators were mostly male and derived from the close family environment of the injured children. All confessed perpetrators stated an "excessive demand" as the reason for the violent shaking of the child. The results of the present study are in line with data from other studies with other legal systems. As many criminal proceedings were closed and the 4 acquittals occurred because the perpetration could not be ascribed to a specific perpetrator, improving the forensic methods for such an unequivocal assignment would be desirable.

This paper describes the variety of information that a tool mark analysis on human tissue can provide based on a case of multiple sharp violence. The perpetrator attacked the victim with a sharp-edged weapon against the head, leaving several deep wounds on the back of the skull bone. Three of those marks on the skull bone could be used for a forensic tool mark examination. Silicone casts of the marks were compared by light microscopy with casts of test marks of Japanese katana swords found at the crime scene. One of the swords could be identified as the one responsible for the marks. In addition, the marks and the test marks were scanned in 3D and examined in a visual on-screen comparison confirming the results from the light microscopic examination. Furthermore, a mathematical approach in which the signatures of the marks from the skull bone and the test marks from the sword were compared by cross correlation confirms those findings. In addition, the aforementioned results were used to determine the orientation of the sword in relation to the cranial bone at the time of the respective impact.

Various parameters can be used for the estimation of gestational age and maturity with arising challenges in the assessment of decomposed bodies. In order to assess gestational age and thus maturity, the study measured the femoral length, the diameter of the distal femoral epiphysis and the presence of the proximal tibial epiphysis compared to a known clavicle length. The resulting gestational ages were compared and statistically evaluated. As a result, discrepancies between the estimated gestational ages became apparent in some cases when comparing the individual structures to be measured. However, there was a clear tendency towards a lower gestational age calculated based on clavicle length and a higher gestational age calculated based on femoral length and distal femoral epiphysis. With regard to the assessment of maturity, it has been concluded that, if the proximal tibial epiphysis is present, maturity can also be assumed based on the diameter of the distal femoral epiphysis and the length of the femur., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2020 Elsevier B.V.

From time to time, severe or fatal injuries caused by small caliber air rifle projectiles are seen. In forensic sciences, the theoretical wounding potential of these weapons and projectiles is widely known. Usually, shots against the skull were reported and, in these cases, penetrating the eyes or thin bone layers of the temporal region. Amongst a huge number of different projectiles available for air guns, sub-caliber 4.4-mm (.173) caliber steel ball projectiles were used in an unusual suicide case. This case led to fundamental questions concerning wound ballistics. An 82-year-old man shot once against his right temporal region and twice into his mouth with a 4.5-mm (.177) caliber air rifle. Because of the exceptionally deep penetration of the base of the skull and the use of spherical-shaped sub-caliber air rifle projectiles, terminal ballistic features were analyzed and compared to results published in forensic literature. Test shots using the same weapon and similar projectiles were fired into ballistic gelatin to measure and calculate basic wound ballistic variables of cal. 4.4-mm (.173) steel balls. In comparison, further test shots with cal. 4.5-mm (.177) steel balls BB (ball bearing), flat-headed and pointed air rifle pellets ("diabolos") were carried out. The theoretical penetration depth in solid bone was calculated with 36.4 mm, and test shots in gelatin from hard contact produced an on-average wound track of 120 mm underlining the potential wounding effect. Furthermore, spherical projectiles could roll back and forth within the barrel, and an air cushion between projectile and breechblock can reduce muzzle velocity by more than half, explaining the retained missile in the temporal region.

Signs of maturity such as weight, length and head circumference are still a measure used to investigate cases of suspected neonaticides as they help to differentiate between newborns born dead or alive. However, limit values for these signs have not changed for a long time. Our study considers whether limit values should have changed and which validity the current ones have. We investigated the cases of 3162 newborns, dividing them into a mature and an immature collective on the basis of the gestational week. Application of these signs of maturity (2500g, 48cm, 34cm) had a high predictive value concerning maturity (>99%), and even applying only one sign of maturity gave a predictive value over 97%. Clinically the mature collective showed a slightly lower rate of ventilation (2% compared to 2.4% for the non-mature collective). Coherences between maternal age/weight and postnatal ventilation could be shown. Coherences with reanimation could not be investigated since the case number was too low. Our results show that, for valid forensic investigation, these numeric signs of maturity have to be supplemented by further investigations and other influencing factors have to be considered. Therefore, clinical instruments such as the Petrussa-Index, clavicule length measuring and foot length measuring must be considered., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Providing concise proof of child abuse relies heavily on clinical findings, such as certain patterns of injury or otherwise not plausibly explainable trauma. Subdural hemorrhaging has been identified as a common occurrence in abused children whereas epidural hemorrhaging is related to accidents. In order to explore this correlation, we retrospectively analyzed clinical data of children under 19 years of age diagnosed with either injury. Reviewing 56 cases of epidural and 38 cases of subdural bleeding, it was shown that subdural bleeding is more common in young children and extremely often a result of suspected abuse in children under 2 years of age. Epidural hemorrhaging however never was found in the context of suspected abuse, was unrelated to other injuries typical for abuse, and did not see a statistically significant increase in any age group. In conformity with currently theorized mechanisms of injury for both types of bleeding, we found that subdural hemorrhaging in young children is closely associated with abuse whereas epidural bleeding is not.

Neonaticide is a serious allegation that needs a complete chain of criminal investigations. In this context, a nuchal cord is considered to be responsible for an infant's death, but there is a clear lack of evidence. The purpose of our study is to reveal if a nuchal cord can be responsible for stillbirth, poor perinatal outcome, or neonatal death in the forensic aspect. We conducted a prospective study in collaboration with the Augustinian Sisters' Hospital in Cologne, Germany in the period from February 2014 to May 2016. Four-hundred eighty-six children were enrolled. All births were assessed regarding the occurrence of an umbilical cord entanglement, and perinatal outcome was measured by arterial blood gas analysis, Apgar after 1, 5, and 10 min after birth as well as the general vitality. The prevalence of a nuchal cord was 16.87%. Apgar decrease and acidosis were significantly associated with a nuchal cord. No adverse perinatal outcome was recorded in this constellation. There was no child death regarding the first 24 h, and no mother experienced a syncope while giving birth. We can conclude that a nuchal cord is not associated with adverse perinatal outcome.

If a case of physical child abuse is suspected in Germany, the general feeling is often that "it does not matter whether you make a report or not" because, generally, no conviction is made anyway. This study investigates the juridical analysis of complaint cases of physical child abuse [criminal complaint parag. 225 StGB (German penal code) with filial victim]. It focuses on the doctor's role and the impact of their practice in relation to a later conviction. It is based on the analysis of 302 files of the enquiry from 2004-2009 from the department of public prosecution in Cologne, Germany. Besides general epidemiological data on the reporting person, the affected child and the presumed offender, the documents were reassessed for the relevance of medical reports for successful convictions. Only 7% (n = 21) of 302 complaints led to a conviction. In 38.1% (n = 8) of those cases, a medical report was mentioned as a piece of evidence, and just in two cases a (legal) medical report was quoted and mentioned as relevant for the conviction. 50% of the complaint cases with legal medical expertise led to a trial. In contrast, only 30.2% with a common medical report and 7.3% without a report led to a trial. The results show how a medical report existed in only a few cases. In those cases, the rate of performed trials was higher than for those without a medical report, but the report played a minor part when reasoning a verdict.

Two captive tiger attacks are presented that took place in Cologne and Münster zoos. Both attacks occurred when the handlers, intent on cleaning the enclosures, entered whilst the tigers accidently retained access to the location, and thus defended their territory against the perceived intruders. Both victims suffered fatal neck injuries from the bites. At Münster, colleagues managed to lure the tiger away from its victim to enable treatment, whilst the Cologne zoo tiger had to be shot in order to allow access to be gained. Whilst it was judged that human error led to the deaths of the experienced zookeepers, the investigation in Münster was closed as no third party was found to be at fault, whereas the Cologne zoo director was initially charged with being negligent. These charges were subsequently dismissed as safety regulations were found to be up to date.

In recent years, increasing attention has been paid to the issue of (fatal) child abuse and neglect, largely due to the media attention garnered by some headline-grabbing cases. If media statements are to be believed, such cases may be an increasing phenomenon. With these published accounts in mind, publicly available statistics should be analysed with respect to the question of whether reliable statements can be formulated based on these figures. It is hypothesised that certain data, e.g., the Innocenti report published by UNICEF in 2003, may be based on unreliable data sources. For this reason, the generation of such data, and the reliability of the data itself, should also be discussed. Our focus was on publicly available German mortality and police crime statistics (Polizeiliche Kriminalstatistik). These data were classified with respect to child age, data origin, and cause of death (murder, culpable homicide, etc.). In our opinion, the available data could not be considered in formulating reliable scientific statements about fatal child abuse and neglect, given the lack of detail and the flawed nature of the basic data. Increasing the number of autopsies of children 0-3 years of age should be considered as a means to ensure the capture of valid, practical, and reliable data. This could bring about some enlightenment and assist in the development of preemptive strategies to decrease the incidence of (fatal) child abuse and neglect.

Background: Female genital mutilation (FGM) occurs mainly in Africa, parts of the Arabian Peninsula and parts of Asia. It is commonly associated with acute complications as well as diverse late/delayed complications. One of the most common of these late complications is progressively enlarging painless cysts of the vulva. Case Report: An 8-year-old girl from Eritrea presented to our paediatric emergency department with a progressively enlarging mass of the vulva. She had undergone a clitoridectomy and partial removal of the labia minora as an infant in Eritrea. We performed surgical excision of the cyst and reconstruction of the labia. Histology showed a traumatic squamous epithelial inclusion cyst of the vulva. Conclusion: Epithelial or dermoid cysts of the vulva following FGM are extremely rare. Symptoms often require surgical intervention. Through increasing migration, more girls and female youths with FGM are likely to present to practices and hospitals in Germany. Thus increased knowledge and awareness of the medical complications of FGM and their treatment will be necessary in years to come.

Cases in which forensic experts cannot draw their conclusions on the basis of primary findings collected by themselves are not uncommon in medico-legal practice. Often only photographs or statements on the course of events are available to investigate the plausibility of reports on how an accident happened. In cases of child abuse it is often claimed that the injuries occurred due to an accident and explanations are adapted to the diagnostic findings or results of the police investigations. This is demonstrated by the death of a 3-year-and-3-month-old child whose body was never found. According to the father, who had disposed of the body and made false statements as to the whereabouts of the child, the toddler had slipped in the bathtub and hit her head against the fittings and the floor of the tub. Some time later he claimed to have found the child dead in the bedroom. Contrary to his version, the prosecution assumed that the child had been killed intentionally The essential points for checking the plausibility of the father's story are presented. As a result, an accidental fall in the bathtub causing a lethal craniocerebral trauma could be ruled out. Accordingly, the accused was sentenced to 6 years and 6 months' imprisonment for bodily harm followed by death according to Sections 227, 223 StGB (German Criminal Code).

When tried in court, mothers accused of neonaticide may claim that the umbilical cord just broke during birth and the newborn child bled to death accordingly. To evaluate the possibility of a breakage of the umbilical cord is the goal of this work. Therefore 25 umbilical cords from neonates of both sexes born at term were stretched using an electrically operated material testing machine and the energy necessary to break them was measured. This experimental set-up equals a static strain, not a dynamic one. The maximum force endured (F max) ranged from 37.24 N to 150.04 N. The average force endured was 79.87 N with a standard deviation of 27.39. The elongation at break varied from 13.24% to a maximum of 119.93%. We found no relationship between the force endured and any of the following parameters: birth weight, pH of the venous umbilical blood, diameter of cord, free length under testing, duration of pregnancy or the mother's age. We performed a literature research and tried to define the circumstances in which a break is more likely to occur, these being malformations, entanglement or disease, e.g. inflammation., (Copyright © 2013 Elsevier Ireland Ltd.

We report a case of a 19-year-old woman who developed a persistent uterine hemorrhage after spontaneous delivery of a healthy child. Emergency laparotomy was indicated and then begun under stable circulatory conditions. Cardiac arrest occurred during the course of massive manual compression and packing of the uterus. After successful resuscitation, a supracervical hysterectomy was performed. During the suturing of the remaining cervix, a second cardiac arrest followed. The procedure was completed under constant external heart massage. Resuscitation was terminated due to the persistence of widened pupils. An autopsy was ordered by the public prosecutor as the manner of death was declared to be unascertained. An X-ray and a CT scan prior to the autopsy showed extensive gas embolism in both arterial and venous vessels extending from the pelvic region to the head. During the autopsy, gas was collected by aspirometer from the right ventricle of the heart. The autopsy showed no additional relevant findings, and gas analysis confirmed the suspicion of air embolism. The histological examination of the excised uterus especially in the corpus/fundus revealed an edema of the local smooth muscle cells and dilated vessels showing no sign of thrombogenesis. Upon evaluation of the clinical records, it became evident that, in addition to uterine atony, there had been a complete uterine inversion. This inversion was manually repositioned. After this maneuver, manual compression was performed. The air embolism, thus, was a complication of the manual repositioning of the uterine inversion. There is no evidence for other possible entries of the detected gas. In order to perform an effective exploration, the availability of all clinical records should be mandatory for medico-legal investigations of unexpected postpartum deaths.

In cases of child abuse, usually, the parents are initial suspects. A common explanation of the parents is that the injuries were caused by a sibling. Child-on-child violence is reported to be very rare in children less than 5 years of age, and thorough investigation by the police, child protective services, and medicolegal examinations are needed to proof or disproof the parents' statement. We report two cases of physical abuse of infants by small children.

In cooperation with the Crime Investigation Agency (Landeskriminalamt) of North Rhine-Westphalia, we carried out a study of 150 cases of (suspected) neonaticide dating from 1993 to 2007 from all over Germany. The autopsy reports and additional expert opinions (if performed) were evaluated for a minimum of 78 variables. Emphasis was placed on the application of special preparation techniques and other special questions arising during the examination of a deceased newborn child. Forty-five percent of the cases remained unsolved, which means that the mother could not be identified. Twenty-seven percent of the corpses were in a state of such severe putrefaction that forensic examination was limited. The main causes of death were all forms of suffocation. The signs of maturity (such as length, weight, and fingernails) were recorded in more than 95 % of the cases. Hydrostatic test of the lung was performed in 96 %, and that of the gastrointestinal tract in 84 %. Given the results of the study, standard protocols and checklists are recommended to facilitate comparability and to ensure the completeness of findings. Full-body X-rays or CT scans should be used to complete viability examinations.

The lung floating test is still an obligatory measure to distinguish whether a newborn was born dead or alive. In order to verify the reliability of the floating test, a new clinical trial should examine the results of current cases and thus expose, if the test is still contemporary. Following the question, if the test is appropriate for the nowadays birth collective, 208 lungs of newborns were tested with the floating test. The test showed the expected correct result in 204 cases. However, it indicated a false negative result in four cases, in which the lungs sank, although prior life had been reported by medical staff. Overall, the study was able to prove that the results of the floating test are reliable in 98 %. Further, there was not a single false-positive result (lungs of a stillborn swim). Nevertheless, the test demonstrates that a negative test result cannot be taken as proof for a newborn never to have breathed at all.
