Epigenetic differences in stress response gene FKBP5 among children with abusive vs accidental injuries.

BACKGROUND: Survivors of child abuse experience high rates of adverse physical and mental health outcomes. Epigenetic alterations in the stress response system, the FKBP5 gene specifically, have been implicated as one mechanism that may link abuse to lifelong health issues. Prior studies primarily included older individuals with a remote history of maltreatment; our objective was to test for differential methylation of FKBP5 in children with abusive vs accidental injuries at the time of diagnosis. METHODS: We conducted a cross-sectional pilot study of acutely injured children <4 years old at two children's hospitals (n = 82). Research personnel collected injury histories, buccal swabs (n = 65), and blood samples (n = 25) to measure DNA methylation. An expert panel classified the injuries as abusive, accidental, or indeterminate. RESULTS: Children with abusive as compared to accidental injuries had lower methylation of the FKBP5 promoter in buccal and blood cells, even after controlling for injury severity, socioeconomic status, and psychosocial risk factors. CONCLUSION: These findings suggest that epigenetic variation in FKBP5 may occur at the earliest indication of abuse and may be associated with delayed resolution of the HPA axis stress response. Additional testing for epigenetic differences in larger sample sizes is needed to further verify these findings. IMPACT: Children (<4 years old) with abusive compared to accidental injuries showed lower methylation of the FKBP5 promoter in buccal and blood cells at the time of initial diagnosis even after controlling for injury severity, socioeconomic status, and psychosocial risk factors. Early childhood physical abuse may impact the epigenetic regulation of the stress response system, including demethylation within promoters and enhancers of the FKBP5 gene, even at the earliest indication of abuse. The findings are important because unmitigated stress is associated with adverse health outcomes throughout the life-course.

The Forensic Assessment for Immigration Relief (FAIR) clinic: A faculty-led, pediatric clinic model.

Since 2019, the number of children apprehended by the United States Custom and Border Patrol at the southern border continues to increase. Many of these children are fleeing violence and extreme poverty and qualify for several forms of humanitarian relief. Trained pediatric health professionals have an essential role to play in documenting evidence to support their petitions. The goal of a forensic medical and psychological evaluation is to establish the facts related to the reported incident(s), provide forensic evidence to support these claims, and provide an expert opinion on the degree to which a finding correlates with the client's reports through a written affidavit. Research studies have demonstrated a significant increase in asylum grant rate for cases that include an evaluation. As demand for forensic evaluations has grown, multiple clinic models have emerged, including volunteer networks, student-led clinics, and faculty-led clinics. The Forensic Assessment for Immigration Relief (FAIR) Clinic offers a sustainable infrastructure while emphasizing the training of pediatric healthcare professionals on the conduct of trauma-informed, culturally attuned, and developmentally appropriate forensic evaluations. This paper outlines the year-long process of developing and launching a clinic specializing in pediatric forensic medical and psychological evaluations as a blueprint for replication.

Examining Cases of Child Physical Abuse Evaluations to Identify Opportunities to Improve Intimate Partner Violence Screening in Pediatric Emergency Departments.

The association between child maltreatment and intimate partner violence (IPV) is well supported. Universal IPV screening has been recommended by the American Academy of Pediatrics and the United States Preventative Task Force, and many children's hospitals have established screening protocols. However, the yield and best screening method in families undergoing a child physical abuse (PA) evaluation have not been fully explored. To determine if there is a discrepancy in IPV disclosures between universal IPV screening completed during pediatric emergency department (PED) triage ("triage screening") and IPV screening by a social worker ("social work screening") in families of children who were evaluated for PA. Caregivers of children who presented to an urban tertiary PED and underwent an evaluation for PA via a child abuse pediatrics consult. A retrospective chart review was completed. Data collection included: caregiver responses to both triage screening and social work screening, interview setting details and participants, the child's injuries, and details of the family's reported IPV experiences. Our study (N = 329) revealed that social work screening produced significantly more positive IPV disclosures than triage screening (14.0% vs. 4.3%, p < .001). Additionally, non-IPV violence concerns were identified in 35.7% (n = 5) of the positive triage screens, whereas social work screens had none. These results highlight the benefits of IPV screening by social work in high-risk scenarios, such as child PA evaluations, regardless of universal IPV screening results. Exploring differences between the two screening methods can inform decisions about screening protocols to improve IPV identification in high-risk populations.

Evaluation for Bleeding Disorders in Suspected Child Abuse.

Bruising or bleeding in a child can raise the concern for child abuse. Assessing whether the findings are the result of trauma and/or whether the child has a bleeding disorder is critical. Many bleeding disorders are rare, and not every child with bruising/bleeding that may raise a concern for abuse requires an evaluation for bleeding disorders. However, in some instances, bleeding disorders can present in a manner similar to child abuse. Bleeding disorders cannot be ruled out solely on the basis of patient and family history, no matter how extensive. The history and clinical evaluation can be used to determine the necessity of an evaluation for a possible bleeding disorder, and prevalence and known clinical presentations of individual bleeding disorders can be used to guide the extent of laboratory testing. This clinical report provides guidance to pediatricians and other clinicians regarding the evaluation for bleeding disorders when child abuse is suspected.

Identifying Maltreatment in Infants and Young Children Presenting With Fractures: Does Age Matter?

OBJECTIVES: Child abuse is a significant cause of morbidity and mortality in preverbal children who cannot explain their injuries. Fractures are among the most common injuries associated with abuse but of themselves fractures may not be recognized as abusive until a comprehensive child abuse evaluation is completed, often prompted by other signs or subjective features. We sought to determine which children presenting with rib or long-bone fractures should undergo a routine abuse evaluation based on age. METHODS: A systematic review searching Ovid, PubMed/Medline, Scopus, and CINAHL from 1980 to 2020 was performed. An evidence-based framework was generated by a consensus panel and applied to the results of the systematic review to form recommendations. Fifteen articles were suitable for final analysis. RESULTS: Studies with comparable age ranges of subjects and sufficient evidence to meet the determination of abuse standard for pediatric patients with rib, humeral, and femoral fractures were identified. Seventy-seven percent of children presenting with rib fractures aged less than 3 years were abused; when those involved in motor vehicle collisions were excluded, 96% were abused. Abuse was identified in 48% of children less than 18 months with humeral fractures. Among those with femoral fractures, abuse was diagnosed in 34% and 25% of children aged less than 12 and 18 months, respectively. CONCLUSION: Among children who were not in an independently verified incident, the authors strongly recommend routine evaluation for child abuse, including specialty child abuse consultation, for: 1) children aged less than 3 years old presenting with rib fractures and 2) children aged less than 18 months presenting with humeral or femoral fractures (Level of Evidence: III Review).

Characteristics of accidental versus abusive pediatric burn injuries in an urban burn center over a 14-year period.

The aim of this study was to determine the demographic and associated characteristics of abusive burn injuries in children. Understanding the characteristics of burn injuries may help clinicians differentiate and recognize abusive injuries. We conducted a retrospective study of patients less than 5 years old admitted to an urban burn center from March 1999 to July 2013. Per protocol, all patients with burn injuries were evaluated by a multidisciplinary team (child abuse pediatrician, social worker, and nurse clinician). Demographic information, social risk factors, clinical presentation, caregiver at time of injury, radiographic studies and results, multidisciplinary team determination, and the Department of Children and Family Services investigation outcome were abstracted from the American Burn Association Burn Registry and patient's chart. Patient characteristics were evaluated with abuse status through Wilcoxon rank sum tests for continuous variables and chi-square tests or Fisher's exact test for categorical variables. A multiple logistic regression was fit to identify factors associated with abusive burns. One hundred and ten patients under 5 years were categorized as abuse (38) or accident (72). Demographic characteristics were similar between the abuse and accident groups. A determination of abuse was significantly associated with caregiver type (paramour), site of incident (outside of kitchen), time to seeking help (>4 hours), and the presence of nonburn skin injuries. A detailed history of the burn mechanism as well as psychosocial family risk factors are critical when evaluating pediatric patients with burn injuries, as it may assist the physician in distinguishing abusive from accidental burn injuries.

Understanding humerus fractures in young children: Abuse or not abuse?

Fractures are the second most common abusive injury occurring in young children, particularly those under 2 years of age. The humerus is often affected. To better identify factors discriminating between abusive and non-abusive humerus fractures, this retrospective study examined the characteristics and mechanisms of injuries causing humerus fractures in children less than 18 months of age. Electronic medical records were reviewed for eligible patients evaluated between September 1, 2007 and January 1, 2012 at two children's hospitals in Chicago, IL. The main outcome measures were the type of fracture and the etiology of the fracture (abuse vs not abuse). The 97 eligible patients had 100 humerus fractures. The most common fracture location was the distal humerus (65%) and the most common fracture type was supracondylar (48%). Child Protection Teams evaluated 44 patients (45%) and determined that 24 of those had 25 fractures caused by abuse (25% of the total study population).Among children with fractures determined to have been caused by abuse, the most common location was the distal humerus (50%) and the most common types were transverse and oblique (25% each); however, transverse and oblique fractures were also seen in patients whose injuries were determined to have been non-abusive. A younger age, non-ambulatory developmental stage, and the presence of additional injuries were significantly associated with abusive fractures. Caregivers did not provide a mechanism of injury for half of children with abusive fractures, whereas caregivers provided some explanation for all children with non-abusive fractures.

Understanding forearm fractures in young children: Abuse or not abuse?

This retrospective study describes the characteristics and mechanisms of forearm fractures in children <18 months adding to the evidence-base about forearm fractures. It also examines which features of forearm fractures in young children may help discriminate between abusive and noninflicted injuries. Electronic medical records were reviewed for eligible patients evaluated between September 1, 2007 and January 1, 2012 at two children's hospitals in Chicago, IL. The main outcome measures were the type of fracture and the etiology of the fracture (abuse versus not abuse). The 135 included patients sustained 216 forearm fractures. Most were buckle (57%) or transverse (26%). Child protection teams evaluated 47 (35%) of the patients and diagnosed 11 (23%) as having fractures caused by abuse. Children with abusive versus non-inflicted injuries had significant differences in age (median age 7 versus 12 months), race, and presence of additional injuries. Children with abusive forearm fractures often presented without an explanation or a changing history for the injury. Children with non-inflicted forearm fractures often presented after a fall. No particular type of forearm fracture was specific for child abuse. Any forearm fracture in a young child should be evaluated with special attention to the details of the history and the presence of other injuries. Young age, additional injuries, and an absent or inconsistent explanation should increase concern that the fracture was caused by child abuse.
