Background: The findings of studies on the frequency of violence against children imply that many cases go undetected. Methods: Selective literature review based on a search of different databases for publications on all types of violence against children, except sexual abuse. Results: The physical abuse of children can involve blunt trauma, thermal injury, and the so-called shaking trauma syndrome (STS). Physical and psychological child neglect have very serious long-term effects. It can be difficult to draw a clear distinction of child abuse and neglect on the one hand, and acceptable behavior on the other, because of the varying social acceptance of certain child-raising practices. Münchhausen's syndrome by proxy (MSbP) is a rare, special type of child abuse. Conclusion: At the beginning of the 21st century, well-established normative structures are in place to protect children against abuse and neglect, and the available help from social organizations can also have a preventive effect. Further improvements will depend on interdisciplinary coordination and better training of specialists in all of the involved disciplines. [ABSTRACT FROM AUTHOR]

Central nervous system-associated lesions can frequently be found in abusive head trauma (AHT) cases. Since there are frequently no visible signs of injury on the body surface, the diagnosis of AHT can be challenging. In particular, if the affected child shows only isolated neurological symptoms, these are often misinterpreted as a minor illness. Using a retrospective study design at three university hospitals, 72 medico-legal cases of "shaken baby syndrome" - a common variant of AHT - were analyzed. A comparison between confession cases (n=15) and non-confession cases was used in order to reduce the risk of circular reasoning. The most common neurological symptoms in the present cases were: epileptic seizures (44 %), pallor (37 %), somnolence (31 %), reduced muscle tone (25 %), vomiting (20 %) and unconsciousness (15 %). There were also no statistically significant differences between confession and non-confession cases, nor when comparing the simultaneous presence of skin or skeletal lesions. The combination of several symptoms serves as an indicator for the presence of AHT and should lead to further diagnostic measures under the hypothesis of the presence of an AHT in clinical observation., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2024 The Authors.

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.

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 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.

Accidents constitute one of the greatest risks to children, yet there are few medical reports that discuss the subject of accidental asphyxia. However, a systematic analysis of all documented cases in Germany over the years 2000-2008 has now been conducted, aiming at identifying patterns of accidental asphyxia, deducing findings, defining avoidance measures and recommending ways of increasing product safety and taking possible precautions. The analysis is based on a detailed retrospective analysis of all 91 relevant autopsy reports from 24 different German forensic institutes. A variety of demographic and morphological data was systematically collected and analysed. In 84 of the 91 cases, the sex of the victim was reported, resulting in a total of 57 boys (68 %) and 27 girls (32 %). The age spread ranged between 1 day and 14 years, with an average of 5.9 years. Most accidents occurred in the first year of life (20 %) or between the ages of 1 and 2 years (13 %). In 46 % of cases, the cause of death was strangulation, with the majority occurring in the home environment. In 31 % of all cases, the cause of death was positional asphyxia, the majority resulting from chest compression. In 23 % of cases, the cause of death was aspiration, mainly of foreign bodies. Today, accidental asphyxiation is a rare cause of death in children in Germany. Nevertheless, the majority of cases could have been avoided. Future incidence can be reduced by implementing two major precautions: increasing product safety and educating parents of potentially fatal risks. Specific recommendations relate to children's beds, toys and food.

In cases of suspected neonaticide, the results of a forensic autopsy might be important for conviction or acquittal. But autopsy findings in dead newborns are often unspecific and can rarely provide corroborative evidence of inflicted injury, as they are known to occur during normal birth as well. In our study, we examined 59 vaginally delivered, healthy newborns within the first 30 min after birth to know more about the prevalence and possible correlations of a caput succedaneum and facial petechiae. Caput succedaneum occurred in 33.9%, facial petechiae in 20.3%. As for the occurrence of caput succedaneum, statistically significant differences could be shown for the duration of delivery and the mother's parity. These correlations could not be shown for the occurrence of facial petechiae. Within the scope of our study, we could demonstrate that neither caput succedaneum nor facial petechiae are rare findings in healthy newborns. In the forensic investigation of suspected neonaticide, their potential significance can only be ascertained together with further investigations of the circumstances of death and a thorough forensic pathological autopsy.

Many scientists of varying clinical backgrounds have described the phenomenon of spermaturia in animals, adolescents as well as fertile and infertile men. Nevertheless, research for an expert opinion on a law case in the field of forensic medicine revealed a lack of valid information about the longevity of spermatozoa in post-ejaculatory urine (PEU) of fertile men. Our goal was to measure the appearance of vivid sperm in PEU while considering the factor of time in order to predict a realistic interval, in which positive sperm findings might occur. Therefore ten healthy, young men donated their sperm for fertility analysis and a urine sample prior to and after ejaculation. The time intervals between ejaculation and the first micturition were preset ranging between 30 min and maximal 11h. Each ejaculate underwent a semen analysis. The pre- and post-ejaculatory urine samples were screened for the presence of viable and motile spermatozoa. Semen parameters were determined and related to the sperm findings in the precipitate of the urine samples. The amount, the viability and motility status of the detected spermatozoa were recorded after each preset time interval. The results showed that none of the 10 participants had sperm in their urine samples prior to ejaculation. The average sperm concentration was 50.1+/-25.8 million/ml. After a time span of 30 min 59.5% of the first fractions of PEU samples were sperm positive, after 2 and 4h still 70%, and after 5h sperm were no longer detected. The last motile spermatozoa could be found after 4.5h. It seems that remaining sperm in the urethra are washed out with the first micturition in the majority of fertile men, however, the conclusion as to whether sperm findings >5h after ejaculation are improbable needs to be confirmed by further investigations., (2009 Elsevier Ireland Ltd.

This investigation presents the retrospective evaluation of paternity testing done as a "second opinion" in the last four years at the Institutes of Legal Medicine in Jena, Greifswald, and Kiel (Germany). All analyses were court-ordered and were preceded by paternity tests of "private" labs. The cases were selected in chronological order without any further exclusion criteria. A total of 59 cases, in which "private" laboratories from all regions of Germany had already performed paternity tests, were evaluated. In all cases, analyses were mainly done by PCR-based STR-typing (8 - 20 STRs). 18 % of the investigated "private" expert opinions showed a false determination of alleles. In two cases, paternity was wrongly confirmed or excluded. The reasons for the mistakes of private laboratories were hard to analyse, since most labs did not provide sufficient information (e.g. alleles, kits and chemicals used) in the written test results. In several cases, not even the typing results were revealed. Furthermore, in paternity testing of "private" labs the identity of the persons examined was usually not assured (e. g. by photo documentation or fingerprints) adding to the problem of insufficient test result reliability.

A dead female neonate was brought to a children's hospital by the mother. The MRI scan suggested a malformation of the brain. Because of the other circumstances of the case (the mother left the hospital unauthorizedly), a forensic autopsy was ordered, in the course of which the brain was removed while the head was totally immersed in water. This method, which was introduced by Prahlow et al., helps to obtain intact brain specimens without interfering with the necessary medicolegal preparations to determine whether the child was born alive. Neuropathological examinations classified the cerebral malformation as (lethal) lissencephaly. Further investigations showed that the mother had lived in Germany without a residence permit.
