Child Sexual Abuse: Comparison of Male and Female Victims.

ABSTRACT: In the scientific literature, few authors deal with child sexual abuse (CSA) in boys. In addition, these authors debate this phenomenon in most available articles without statistically evaluating the occurrence of different or similar distributions of variables under sex. In light of the above, the authors compared multiple variables between female and male samples. The aim was to explore the characteristics of boys' CSA, identifying the main differences existing compared with the same phenomenon occurring in girls. The authors selected 2 samples for sex: group A, females; group B, males. The authors statistically compared the main variables between the 2 groups. The study yielded the following main results: the population was characterized by 607 children (476 were females-group A; 131 were males-group B); the variables' source of the referral and the type of anogenital findings were statistically significant. These data gave new insights into the CSA phenomenon. Because this study pointed out that sexual abuse does not have the same characteristics in boys and girls, researchers and safeguarding agencies should consider the abovementioned differences when planning preventive strategies against CSA.

Artificial Intelligence and Child Abuse and Neglect: A Systematic Review.

All societies should carefully address the child abuse and neglect phenomenon due to its acute and chronic sequelae. Even if artificial intelligence (AI) implementation in this field could be helpful, the state of the art of this implementation is not known. No studies have comprehensively reviewed the types of AI models that have been developed/validated. Furthermore, no indications about the risk of bias in these studies are available. For these reasons, the authors conducted a systematic review of the PubMed database to answer the following questions: "what is the state of the art about the development and/or validation of AI predictive models useful to contrast child abuse and neglect phenomenon?"; "which is the risk of bias of the included articles?". The inclusion criteria were: articles written in English and dated from January 1985 to 31 March 2023; publications that used a medical and/or protective service dataset to develop and/or validate AI prediction models. The reviewers screened 413 articles. Among them, seven papers were included. Their analysis showed that: the types of input data were heterogeneous; artificial neural networks, convolutional neural networks, and natural language processing were used; the datasets had a median size of 2600 cases; the risk of bias was high for all studies. The results of the review pointed out that the implementation of AI in the child abuse and neglect field lagged compared to other medical fields. Furthermore, the evaluation of the risk of bias suggested that future studies should provide an appropriate choice of sample size, validation, and management of overfitting, optimism, and missing data.

Knowledge of child abuse and neglect in nursing students: Assessment and perspectives.

Misdiagnosis of child abuse and neglect can delay early treatment. Some authors have pointed out that nurses can miss child abuse and neglect diagnoses due to a lack of knowledge. It is unclear whether the lack of knowledge is due to students' insufficient preparation in nursing school and/or a deficiency in continuing education. An 18-item questionnaire was administered to final-year nursing students to assess their degree of knowledge on child abuse and neglect and to evaluate if the lack of knowledge was due to insufficient teaching/training during nursing school. The students were also asked to evaluate themselves by assigning a score to their knowledge. A statistical comparison was performed to define whether sufficient/insufficient results were associated with the following variables: sex, pediatric or general nursing student, attending pediatric lectures, training in pediatric wards/ambulatories, and attending specific lectures on child abuse and neglect. The study population comprised 175 students (154 females, 20 males, 1 unknown). Exactly 66.3% of the participants had ≤9/18 correct answers. Of all students, 77.7% self-evaluated their level of knowledge as ≤5/10. The comparisons yielded statistically significant differences between the groups with sufficient objective knowledge and those unrelated to training in pediatric wards/ambulatories or pediatric nursing students. Overall, there was little objective knowledge on the subject, which may be related to insufficient teaching/training in nursing schools. Useful corrective strategies include further teaching on child abuse and neglect, preferably using a practical approach. Further, common teaching/training programs should be conducted by both pediatric and general nursing schools.

Unexpected stillbirth from umbilical cord hematoma.

Background: Umbilical cord hematomas (UCHs) can cause life-threatening outcomes, although extremely uncommon. They can lead to fetal distress and stillbirth. They have been observed in about 1:5500 pregnancies; they are associated with poor outcome in about the 50% of all cases. UCHs commonly occur due to rupture/lesion of umbilical vein's walls, or less frequently of umbilical arteries' ones. Case Report: We present a case of a fetal demise which acutely and unexpectedly occurred in the last phases of labor. In this fetus, the identification of the cause of death was made only after post-mortem examination. The present report depicts the uncommon eventuality of umbilical cord hematomas which can cause unexpected fetal demise. Conclusion: This case points out that in these cases careful examination of umbilical cord's macroscopic/microscopic examination is fundamental to clarify the natural cause of fetal death for statistical purposes; to close parents' mourning process; to ascertain medical malpractice claims.

An Unexpected Death Due to a Subclinical Pheochromocytoma After an Induced Abortion.

ABSTRACT: Deaths due to hypertensive crisis can be unexplained because of the impossibility to identify-before the decease-the specific cause of the crisis. In these cases, autopsy and microscopic examinations are needed. It can happen that the request to conduct these examinations can be submitted to forensic pathologists by prosecutors to ascertain medical malpractice claims. Indeed, we report the case of a 36-year-old woman who died after a minimally invasive medical procedure because of the occurrence of a severe hypertensive crisis. After death, the woman's relatives raised formal complaint for medical malpractice. For this reason, the prosecutor ordered to perform an autopsy. Examining the abdominal cavity, the forensic pathologists identified the left adrenal gland as expanded; in correspondence with organ's medulla, there was a gray and noncapsulated mass. Immunohistochemistry was performed: the microscopic samples were diffusely positive for chromogranin A, suggesting the diagnosis of a subclinical pheochromocytoma. In light of the above, medical malpractice was excluded. This case highlights that forensic pathologists should be aware that, in case of unexpected deaths due to hypertensive crisis, adrenal glands should be always accurately evaluated, performing specific immunohistochemistry study to exclude the presence of a pheochromocytoma.

Child abuse and neglect: Are future medical doctors prepared?

Diagnosis of child abuse and neglect is a challenging matter: in case of misdiagnosis, the child cannot benefit from an early treatment; erroneous interpretation may generate legal issues. Some studies reported physicians' lack of knowledge in child abuse and neglect. However, it is not clear if the reasons of this lack relay on an insufficient preparation of students during medical school and/or a deficiency in continuing medical education during/after fellowships. For these reasons, the authors of the present manuscript administered a questionnaire to last year medical students to: evaluate the degree of knowledge on this thematic in a medical student sample; understand if the abovementioned lack may be due to insufficient preparation of students during medical school. Study population included 179 students. The 77.7% demonstrated a low knowledge of this thematic, but they showed a high insight of their lack. The authors pointed out that medical school education can represent a weak point in future medical doctor knowledge on child abuse and neglect. It also allowed to identify as study sample's medical students had high awareness of their lacks in this field. In addition, comparison of medical schools from different geographical areas suggested common issues independent of which accreditation system is implemented. Thus - independent of which corrective strategy will be planned - the study highlighted necessity for each medical school to define: its current ability to properly train students in child abuse and neglect; students' awareness of their level of expertise. This can help schools to identify the most suitable correctives.

Stillbirth diagnosis and classification: comparison of ReCoDe and ICD-PM systems.

OBJECTIVES: The identification of causes of stillbirth (SB) can be a challenge due to several different classification systems of SB causes. In the scientific literature there is a continuous emergence of SB classification systems, not allowing uniform data collection and comparisons between populations from different geographical areas. For these reasons, this study compared two of the most used SB classifications, aiming to identify which of them should be preferable. METHODS: A total of 191 SBs were retrospectively classified by a panel composed by three experienced-physicians throughout the ReCoDe and ICD-PM systems to evaluate which classification minimizes unclassified/unspecified cases. In addition, intra and inter-rater agreements were calculated. RESULTS: ReCoDe defined: the 23.6% of cases as unexplained, placental insufficiency in the 14.1%, lethal congenital anomalies in the 12%, infection in the 9.4%, abruptio in the 7.3%, and chorioamnionitis in the 7.3%. ICD-PM defined: the 20.9% of cases as unspecified, antepartum hypoxia in the 44%, congenital malformations, deformations, and chromosomal abnormalities in the 11.5%, and infection in the 11.5%. For ReCoDe, inter-rater was agreement of 0.58; intra-rater agreements were 0.78 and 0.79. For ICD-PM, inter-rater agreement was 0.54; intra-rater agreements were of 0.76 and 0.71. CONCLUSIONS: There is no significant difference between ReCoDe and ICD-PM classifications in minimizing unexplained/unspecified cases. Inter and intra-rater agreements were largely suboptimal for both ReCoDe and ICD-PM due to their lack of specific guidelines which can facilitate the interpretation. Thus, the authors suggest correctives strategies: the implementation of specific guidelines and illustrative case reports to easily solve interpretation issues.

Micro-CT processing's effects on microscopic appearance of human fetal cardiac samples.

Higher resolution than common computed tomography has been reached through Micro-Computed Tomography (micro-CT) on small samples. Emerging forensic applications of micro-CT are the study of fetal/infant organs and whole fetuses, and their two/three-dimension reconstruction; it allows: to facilitate pathologists' role in the identification of causes of fetal stillbirth and of infant death; to create digital two and/or three-dimension representations of fetal/infant organs and whole fetuses which can be easily discussed in civil and/or penal courts. Micro-CT reconstructs cardiac anatomy of animal and human sample. There are no studies that are specifically aimed to evaluate possible effects of micro-CT processing on cardiac microscopic evaluation. This study analyzed microscopic effects of micro-CT processing on human-fetal-hearts. After processing with Lugol-solution or Microfil-MV-122-injection in coronary branches, fetal hearts underwent micro-CT scan. Then, hearts were microscopically analyzed using hematoxylin/eosin, trichrome, immunohistochemistry (IHC) for actin-protein, and IHC for desmin-intermediate-filament stains. In all cases staining was present in all fields. In all slides, disarranged myocardial proteins with increase of inter filaments and inter cellular spaces was reported. This manuscript allowed to observe post micro-CT appropriate staining and antigenic reactivity, and to identify cytoarchitecture modifications that could compromise slides' microscopic evaluation. It also highlighted a possible role of micro-CT determining this cytoarchitecture phenomenon.

Immunohistochemistry patterns of SARS-CoV-2 deaths in forensic autopsies.

SARS-CoV-2 infection was a leading cause of death in 2020 worldwide. It can evolve determining sudden dyspnea and death without hospitalization and/or a nasopharyngeal swab. These cases can need the intervention of forensic pathologists in order to identify causes of death and to clarify malpractice claims. For these reasons, it would be useful to identify immunohistochemistry patterns of SARS-CoV-2 deaths. Thus, the authors described immunohistochemistry findings of two Patients: perivascular recruitment of T-cells in lung parenchyma, massive activation of cytotoxic cells (especially in spleen's parenchyma), and diffuse platelet aggregation in medium/small vessels. In addition, they analyzed these data in the light of the scientific literature, pointing out meaningful immunohistochemistry patterns in order to better understand SARS-CoV-2 pathophysiology process and to clearly identify causes/contributing factors of death in forensic routine.

Minor migrants' age estimation: Comparison of two dental methods.

In case of minor migrants, absence of valid identification documents that clearly define age is a critical issue, because without these data the child cannot enjoy the rights provided by the Convention on the Rights of the Child. Differentiation between minors and adults is fundamental when age is disputed in human identification, asylum seeking, criminal liability, and child abuse fields. Few indications are available about qualitative/statistical agreement of different age estimation methods. Ages of 301 individuals were estimated through two dental methods in order to: determine quantitative and statistical agreements in legal age definition; identify practical recommendations. The study pointed out discrepancy between the two methods in 7/301 cases. From a statistical point of view, this finding corresponded to an almost perfect agreement. Thus, authors suggested that the two methods can be alternately used for legal age assessment, but operators should use both methods when the estimated age is 18.5 years.

Dental autopsy recommendations in SARS-CoV-2 infected cases.

Unidentified human remains with unknown medical history can always pose biological hazards to forensic pathologists and odontologists, including hepatitis C, HIV infection, Middle East respiratory syndrome (MERS), hemorrhagic fever viruses such as Ebola, meningitis and now Sars-Cov2. The pandemic of the new coronavirus disease (COVID-19) has reached 185 Countries with an increasing number of deaths. Forensic pathologists and odontologists may find themselves having to perform an identification autopsy to confirmed or suspected Sars-Cov2 positive deaths. By respecting the entire set of universal precautions and recommendations the highlighted risks can be minimized, and best practice in human identification should always be a priority for human rights of the dead. The following article is a summary of the recommendations for conducting dental autopsies and management of suspected COVID-19 cases.

Differential diagnosis between physical maltreatment and cupping practices in a suspected child abuse case.

Physical maltreatment is one of the most common forms of child abuse. Cutaneous injuries often raise the suspicion of child maltreatment. Nevertheless, among health professionals there is still uncertainty in the evaluation of such injuries. In the literature, there are few indications about the most important factors that allow the differentiation of physical abuse findings from signs/lesions that are caused by "folk medicine practices" with similar presentations. We report the case of two brothers who were brought to the Emergency Department of a pediatric hospital by their father because each of them showed one painful, circular and red-purple bruise on their back. Suspecting child abuse, the emergency physicians reported the case to a multidisciplinary unit (dedicated to child abuse). After a careful physical examination, psychological interviews, as well as the evaluation of their medical history, the operators pointed out that the lesions were the result of cupping practices (a form of folk medicine). This case highlights the need for a multidisciplinary approach and demonstrates the importance of a careful evaluation of the cultural background of the family.

Death Shortly after Delivery Caused by Congenital High Airway Obstruction Syndrome.

Background: Congenital High Airway Obstruction Syndrome (CHAOS) is an uncommon anomaly. Prenatal ultrasonography allows a prenatal diagnosis to prepare for immediate surgical correction at birth. If the obstruction is severe and a correct therapeutic approach is not planned, CHAOS can cause neonatal death shortly after delivery from a potentially surgically correctable lesion.Case report: This neonate died unexpectedly shortly after delivery due to CHAOS. Ultrasonographic findings of enlarged echogenic lungs, dilated airways distal to the obstruction, flattened or inverted diaphragms, or ascites were absent. This was due to a type-II laryngeal-atresia and a type-C esophageal-atresia, with a resultant distal fistula that allowed intrauterine decompression of the fluid in the lungs.Conclusions: The absence of prenatal ultrasonographic findings of CHAOS may be due to a lower fistula between respiratory and gastrointestinal tracts. This set of associations may not be a surgically correctable cause of CHAOS.

Infantile Hypertrophic Cardiomyopathy and Bronchopneumonia as Causes of an Unexpected Death in an 11-Month-Old Child.

Background: Hypertrophic cardiomyopathy is characterized by intrinsic myocardial hypertrophy that is not consequent to hemodynamic stimuli. Infantile hypertrophic cardiomyopathy (<1 year of age) has a frequency of about 3.6 per 1 million children, is usually diagnosed in utero, at birth, or in the first months of life. The most common outcome of this form is heart failure that may result in the death of the child. Case Report: We present an 11-month old infant with hypertrophic cardiomyopathy, complicated by terminal bronchopneumonia, without the typical clinical signs/symptoms in which the diagnosis was made only after postmortem examination. Conclusion: The present report depicts that IHCM may present with the unexpected death of an infant.

Causes of death shortly after delivery and medical malpractice claims in congenital high airway obstruction syndrome: Review of the literature.

Congenital High Airway Obstruction Syndrome is a rare pathology that may conduct the baby to death shortly after delivery. This outcome may cause emotional distress in the parents but it may also generate expensive medical malpractice claims about the reasons why the syndrome was not identified and/or correctly treated. The authors conducted a review of the cases in which Congenital High Airway Obstruction Syndrome caused death of the baby shortly after delivery. Then, they pointed out these ultrasonographic and anatomical reasons why the syndrome may be not identified and/or correctly treated: negative prenatal ultrasonography, recurrence of non-specific findings at prenatal ultrasonography, connection of respiratory and gastrointestinal tracts, tracheal agenesis or atresia, parent's refuse of post-partum therapeutic procedures, multiple malformations of the fetus/child. In conclusion, the authors highlighted that death shortly after delivery is usually caused by specific conditions that are not influenced by healthcare team's practice.

The role of the autopsy in the diagnosis of commotio cordis lethal cases: Review of the literature.

Commotio Cordis (CC) diagnosis is based on the occurrence of a blunt, non-penetrating blow to the chest preceding cardiovascular collapse and the absence of structural damage that would explain any observed effects. In CC lethal cases, the execution of the autopsy represents a possible diagnostic tool. Nevertheless, to date in the literature no author expresses an opinion about the use of the autopsy. In the light of the above, the authors propose a review of the literature about this topic. The review consents to state that the occurrence of a blunt blow to the chest is a necessary element for a lethal CC diagnosis, but it cannot be considered enough. Indeed, because CC is a recognized cause of sudden cardiac death, the autopsy should be always performed to exclude the presence of structural damage that would explain any observed effects. This approach is fundamental in order to achieve an accurate diagnosis and to distinguish CC from other causes of sudden cardiac death. In addition, the authors sustain that in case of autopsy data's lack the authors should not identify CC diagnosis as definitive but as possible.

Child Sexual Abuse Perpetrated by Women: Case Series and Review of the Literature.

The literature on child sexual abuse (CSA) perpetrated by female sexual offenders (FSOs) is exiguous, and many studies have focused on judicial databases. The present retrospective study, instead, analyzed clinical and judicial data of a group of both victims and alleged FSOs, to additionally include women who have not been convicted by the criminal justice system, but who hold strong clinical suspicions of being perpetrators of CSA. The medical records and the Court files of 11 children and their eight suspected FSOs have been collected and critically reviewed in light of the literature to date. This approach allowed for a deeper understanding of the relationship between child and FSO. The authors hypothesize that the victims' severe psychopathological outcomes were a result of a failure to develop appropriate attachments with their prospective caregivers, which could have been damaged by the pathological relationship with FSOs, who were the victims' caregivers.

Self-harm Risk Among Adolescents and the Phenomenon of the "Blue Whale Challenge": Case Series and Review of the Literature.

The "Blue Whale Challenge" is a dangerous Internet phenomenon. As per media reports, it involves a series of life-threatening tasks imposed by a "curator" to "players," who must fulfill the whole list, and it ends with the suicide of the player. The authors report the data of five suspected cases of "Blue Whales" managed from January 2016 to December 2017 by the staff of a unit (the "Bambi Unit" of the Pediatric Hospital "Regina Margherita" of Turin, Italy) that is dedicated to the evaluation of suspected abused children. Then, they analyzed this data in the light of the literature regarding self-harm. This comparison highlights the role of the Internet in the spreading of self-harm behavior among vulnerable adolescents who are characterized by epidemiological, psychological, psychiatric, social, and cultural risk factors. In conclusion, the authors suggest a multidisciplinary and specialized approach in the evaluation of adolescents who committed self-harm activities.
