Non-accidental trauma (NAT) is a major cause of morbidity and mortality for children around the world and most significantly impacts children under one year of age. Prompt and comprehensive treatment of these children relies on a high index of suspicion from any medical provider that treats pediatric patients. This review discusses those most at risk for experiencing NAT, and common initial presentations, to assist providers in the identification of potential victims. In addition, this review provides guidance on the recommended workup for these patients so that the full extent of associated injuries may be identified and the appropriate healthcare team may be assembled.

BACKGROUND: The PediBIRN-7 clinical prediction rule incorporates the (positive or negative) predictive contributions of completed abuse evaluations to estimate abusive head trauma (AHT) probability after abuse evaluation. Applying definitional criteria as proxies for AHT and non-AHT ground truth, it performed with sensitivity 0.73 (95 % CI: 0.66-0.79), specificity 0.87 (95 % CI: 0.82-0.90), and ROC-AUC 0.88 (95 % CI: 0.85-0.92) in its derivation study.
OBJECTIVE: To validate the PediBIRN-7\'s AHT prediction performance in a novel, equivalent, patient population.
METHODS: Consecutive, acutely head-injured children <3 years hospitalized for intensive care across eight sites between 2017 and 2020 with completed skeletal surveys and retinal exams (N = 342).
METHODS: Secondary analysis of an existing, cross-sectional, prospective dataset, including assignment of patient-specific estimates of AHT probability, calculation of AHT prediction performance measures (ROC-AUC, sensitivity, specificity, predictive values), and completion of sensitivity analyses to estimate best- and worst-case prediction performances.
RESULTS: Applying the same definitional criteria, the PediBIRN-7 performed with sensitivity 0.74 (95 % CI: 0.66-0.81), specificity 0.77 (95 % CI: 0.70-0.83), and ROC-AUC 0.83 (95 % CI: 0.78-0.88). The reduction in ROC-AUC was statistically insignificant (p = .07). Applying physicians\' final consensus diagnoses as proxies for AHT and non-AHT ground truth, the PediBIRN-7 performed with sensitivity 0.73 (95 % CI: 0.66-0.79), specificity 0.87 (95 % CI: 0.82-0.90), and ROC-AUC 0.90 (95 % CI: 0.87-0.94). Sensitivity analyses demonstrated minimal changes in rule performance.
CONCLUSIONS: The PediBIRN-7\'s overall AHT prediction performance has been validated in a novel, equivalent, patient population. Its patient-specific estimates of AHT probability can inform physicians\' AHT-related diagnostic reasoning after abuse evaluation.

BACKGROUND: This study investigated the association between child abuse [child neglect (CN), emotional (CEA) and physical abuse (CPA)] and early puberty with special regard to sex-specific effects concerning child and parental perpetrator.
METHODS: Data assessment took place within the framework of the LIFE Child Depression study, a longitudinal study on the development of depressive symptoms and disorders between child- and adulthood in Leipzig, Germany. A sample of 709 children (8-14 years) was recruited from the general population and via psychiatric hospitals. Data on pubertal status were assessed using an instrument for self-assessment of tanner stages (scales of physical pubertal development). Information on menarche was provided by parents. The Parent-Child Conflict Tactics Scales (CTS-PC) served for data on child abuse.
RESULTS: Regarding physical puberty markers, significant correlations were found, especially with child neglect (CN) and child emotional abuse (CEA). Regression analyses, controlling for Body-Mass-Index (BMI) and Socioeconomic Status (SES), revealed that children affected by child neglect perpetrated by mother (CNm) and child emotional abuse (CEA) parent-non-specifically enter puberty significantly earlier. Sex-specific analyses identified child neglect perpetrated by mother (CNm) to be associated with early puberty in girls and child emotional abuse perpetrated by father (CEAf) with early puberty in boys. Concerning the onset of menstruation, there was a significant positive correlation between early menarche and parent-specific and non-specific child neglect (CN), as well as between early menarche and child emotional abuse perpetrated by the mother (CEAm). In regression models that controlled for Body-Mass-Index (BMI) and Socioeconomic Status (SES) no significant associations were maintained. Child physical abuse (CPA) was not associated with early puberty.
CONCLUSIONS: Results outlined child neglect (CN) and child emotional abuse (CEA) to be sex- and perpetrator-specific risk factors for early pubertal development. Knowledge of sex- and perpetrator-specific effects could help clinicians to specify their diagnostic process and to define differential prevention and treatment goals for children with experiences of CN and CEA. Further research on the sex-specific impact of parental CN and CEA on girls\' and boys\' puberty is needed.

Missed cases of child physical abuse (CPA) persist despite known risk factors. Prior studies have not evaluated missed medical appointments as a risk factor for CPA. The objective of this study was to determine if an association exists between missed appointments and hospitalization for CPA. We conducted a 20-year, single health system, retrospective chart review of hospitalized patients ≤36 months of age meeting International Classification of Diseases (ICD) 9/10 criteria for CPA with ≥1 scheduled appointment in our system prior to their admission. Cases were categorized as definite CPA, high likelihood, or no concern for CPA/unable to be determined. Cases identified as definite or high likelihood of CPA were matched (5:1) with controls based on age, distance to primary care provider\'s (PCP\'s) office, sex, prior hospitalization, and race. Missed appointments were compared between cases (n = 146) and controls (n = 730). A significant difference was identified between cases and controls (26 % vs 9 %, p < 0.001) for the median proportion of missed appointments. After adjusting for matched and significant covariates, there was a 3 % increase in a patient\'s odds of admission for CPA for every 1 % increase in missed appointments. We found an association between missed appointments and future admission for CPA. This finding has potential to assist clinicians with CPA risk stratification and future child abuse research. Limitations include single healthcare system, ICD criteria determined by research team, and narrow definition of definite CPA.

Intimate partner violence (IPV) affects 1 in 4 American women, and physical child abuse is reported to occur in 10-67 % of homes with IPV. Routine evaluation of physical abuse in IPV-exposed children is neither widespread nor informed by clinical guidelines. Thus, the true frequency of detectable injuries in IPV-exposed children remains unknown. The purpose of this study was to examine the frequency of injuries in children <3-years-old reported for IPV to a regional child protective services (CPS) office.
In this prospective observational study, we reviewed encounters of children whose caregivers agreed to an evaluation for injuries (physical exam and imaging, if indicated) from July 2019-June 2022. Children were included if: 1) a CPS investigator referred a child for evaluation for injuries (\"non-acute\" evaluation) or 2) a child presented immediately after an IPV incident (\"acute\" evaluation).
Of 326 children <3-years-old reported to the CPS office after IPV exposure, 90 (27.6 %) were evaluated: 81(90 %) presented for a non-acute evaluation, and 21(23 %) were reported to have sustained trauma during the IPV event. Of the 90 children evaluated, 3 (3.3 %, 95 % CI 0.7-9.4) were found to have cutaneous injuries, fractures, and/or intracranial findings. Each was <6-months old and had an \"acute\" evaluation.
In this study of children reported to CPS for IPV exposure, a small percentage was found to have injuries. A multi-center study that examines the frequency of and factors that increase the risk of abusive injuries in IPV-exposed children may ensure that testing targets children at highest risk.

Suspicion for child abuse is influenced by implicit biases. Evaluation by a Child Abuse Pediatrician (CAP) may reduce avoidable child protective services (CPS) referrals. Our objective was to investigate the association of patient demographic, social and clinical characteristics with CPS referral before consultation by a CAP (preconsultation referral).
Children<5years-old undergoing in-person CAP consultation for suspected physical abuse from February 2021 through April 2022 were identified in CAPNET, a multicenter child abuse research network. Marginal standardization implemented with logistic regression analysis examined hospital-level variation and identified demographic, social, and clinical factors associated with preconsultation referral adjusting for CAP\'s final assessment of abuse likelihood.
Among the 61% (1005/1657) of cases with preconsultation referral, the CAP consultant had low concern for abuse in 38% (384/1005). Preconsultation referrals ranged from 25% to 78% of cases across 10 hospitals (P < .001). In multivariable analyses, preconsultation referral was associated with public insurance, caregiver history of CPS involvement, history of intimate partner violence, higher CAP level of concern for abuse, hospital transfer, and near-fatality (all P < .05). The difference in preconsultation referral prevalence for children with public versus private insurance was significant for children with low CAP concern for abuse (52% vs 38%) but not those with higher concern for abuse (73% vs 73%), (P = .023 for interaction of insurance and abuse likelihood category). There were no differences in preconsultation referral based on race or ethnicity.
Biases based on socioeconomic status and social factors may impact decisions to refer to CPS before CAP consultation.

Examine the epidemiology of subspecialty physical abuse evaluations within CAPNET, a multicenter child abuse pediatrics research network.
We conducted a cross-sectional study of children <10 years old who underwent an evaluation (in-person or remote) by a child abuse pediatrician (CAP) due to concerns for physical abuse at ten CAPNET hospital systems from February 2021 through December 2021.
Among 3667 patients with 3721 encounters, 69.4% were <3 years old; 44.3% <1 year old, 59.1% male; 27.1% Black; 57.8% White, 17.0% Hispanic; and 71.0 % had public insurance. The highest level of care was outpatient/emergency department in 60.7%, inpatient unit in 28.0% and intensive care in 11.4%. CAPs performed 79.1% in-person consultations and 20.9% remote consultations. Overall, the most frequent injuries were bruises (35.2%), fractures (29.0%), and traumatic brain injuries (TBI) (16.2%). Abdominal (1.2%) and spine injuries (1.6%) were uncommon. TBI was diagnosed in 30.6% of infants but only 8.4% of 1-year old children. In 68.2% of cases a report to child protective services (CPS) was made prior to CAP consultation; in 12.4% a report was made after CAP consultation. CAPs reported no concern for abuse in 43.0% of cases and mild/intermediate concern in 22.3%. Only 14.2% were categorized as definite abuse.
Most children in CAPNET were <3 years old with bruises, fractures, or intracranial injuries. CPS reports were frequently made prior to CAP consultation. CAPs had a low level of concern for abuse in majority of cases.

The pediatric subspecialty of Child Abuse Pediatrics (CAP) was certified by the American Board of Medical Subspecialties in 2006. Relative to its impact on pediatric health, CAP-focused research has been relatively under-funded. Multi-center networks related to CAP-focused research have made important advances, but have been limited in scope and duration. CAPNET is multi-center network whose mission is to support CAP-focused research.
To describe the rationale, development, and scope of the CAPNET research network infrastructure, the CAPNET data registry and associated data resources.
Based on existing priorities for CAP-focused research, we used consensus building and iterative testing to establish inclusion criteria, common data elements, data quality assurance, and data sharing processes for children with concerns of physical abuse.
We describe the rationale, methods and intended scope for the development of the CAPNET research network and data registry. CAPNET is currently abstracting data for children <10 years (120 months) old who undergo sub-specialty evaluation for physical abuse at 10 US pediatric centers (approximately 4000 evaluations/year total) using an online data capture form. Data domains include: demographics; visit timing and providers, medical/social history, presentation, examination findings, laboratory and radiographic testing, diagnoses, outcomes, and data for contact children. We describe the methods and criteria for collecting and validating data which are broadly available to CAP investigators.
CAPNET represents a new data resource for the CAP research community and will increase the quantity and quality of CAP-focused research.

Adults\' assessments of the credibility of children\'s reports are affected by factors including the frequency of abuse, reporting delays and the child\'s age. The present study examined whether similar factors affect the perceived credibility of children reporting physical abuse, which is more common than sexual abuse. Two hundred and eight mock jurors read a simulated transcript of a child reporting physical abuse to police and made credibility ratings. Within each transcript, abuse frequency (once, repeated), reporting timing (recent, delayed), police question type (open, closed) and child age (6 or 10 years) were manipulated. The child was considered more credible when the abuse was only experienced once and reported shortly after it occurred, and when prompted with open questions. The child\'s age did not affect credibility judgments. Current findings support recommendations to prioritise open questions with children and provide evidence for extension of the benefits of open questions to children\'s credibility.

OBJECTIVE: This study was aimed at evaluating the levels of knowledge of child abuse among students attending the School of Dental and Oral Medicine at the University of Hamburg- Eppendorf, Germany.
METHODS: This cross-sectional study utilized a self-administered and structured questionnaire, consisting of 23 multiple-choice questions; the questionnaire focused on rating the students\' knowledge of and ability to diagnose child abuse. Each question was analysed with simple descriptive statistics.
RESULTS: The students (181) were aware of their legal and ethical responsibilities towards the children and their parents. More than two-thirds (69.6%) responded positively when asked whether a dentist should be legally responsible to report cases of child abuse brought to their attention. The majority of the students (96.1%) agreed that dentists had an ethical duty to report such cases. However, the students were unable to define or describe the signs, symptoms, and social indicators of child abuse. Approximately 93.4% of the students lacked basic training related to child abuse, while 95.7% of them indicated that there was insufficient training in issues related to child abuse.
CONCLUSIONS: There is a general lack of information regarding child abuse among dentistry students. The majority of the students showed interest in the topic of child abuse and neglect, but were unable to clearly identify the signs and symptoms. More lectures and workshops relating to child abuse should be available to all dentists to reinforce their knowledge as well as to strengthen their confidence when confronted with suspected cases of child abuse.
