Emergency Department Triage Chief Complaints Among Children Evaluated for Physical Abuse Concerns.

OBJECTIVES: The aims of this study were to describe chief complaints provided at emergency department triage for young children ultimately given a diagnosed with injuries concerning for physical abuse and compare chief complaints by hospital child protection team assessment (abuse most likely, accident most likely, undetermined) among children younger than 2 years who were the subject of a report to child protective services. METHODS: This is a retrospective review of children evaluated by the child protection team at an urban children's hospital over a 5-year period. Children younger than 2 years who were the subject of a report to child protective services for suspected physical abuse were included. Chief complaints noted in emergency department triage notes were categorized as follows: 1, medical sign or symptom; 2, accidental trauma incident; 3, identified injury; 4, concern for abuse; or 5, multiple unrelated complaints. Child protection team assessments were categorized as follows: 1, abuse most likely; 2, accident most likely; or 3, undetermined. We used descriptive statistics and tests of association (χ 2 , Fisher exact, Kruskal-Wallis). RESULTS: Median age of the 422 children included was 4.9 months. Child protection team assessment was abuse most likely in 44%, accident most likely in 23%, and undetermined in 34%. Chief complaints in the overall sample were 39% medical, 29% trauma incident, 16% injury, 10% abuse concern, and 6% multiple unrelated. When the abuse most likely and accident most likely groups were compared, medical chief complaints were more common in the former (47% vs 19%, P < 0.001), whereas trauma incident chief complaints were more common in the latter (19% vs 64%, P < 0.001). Most common medical complaints in the abuse most likely group were altered mental status, abnormal limb use, swelling, pain, apnea, and vomiting. CONCLUSION: Many children found to have injuries concerning for abuse (47%) present without mention of trauma, injury, or abuse concern as part of the chief complaint. Our findings suggest important topics to include in training physicians about recognition of abuse.

The eye in child abuse.

Child physical abuse may result in a range of injuries to the globe and surrounding tissues. These injuries have varying degrees of specificity for abuse, and no pattern of injury is unique to abuse. Easily overlooked eye injuries in non-ambulatory infants often portend more severe abuse and require careful evaluation for occult injury when they are unexplained. Retinal hemorrhages are most often a sign of significant trauma and the severity of the hemorrhages generally parallels the severity of neurological trauma. Ophthalmologists contribute important data that more easily distinguish medical disease from trauma, but caution is needed in differentiating accidental from inflicted trauma. This distinction requires careful consideration of the complete clinical data and occasionally on additional law enforcement or child welfare investigation.

Prevalence and Causes of Subconjunctival Hemorrhage in Children.

OBJECTIVE: Subconjunctival hemorrhage (SCH) is a reported sign of occult abusive injury, but there are limited published data about SCH during childhood. We sought to determine the prevalence and causes of SCH in children. METHODS: This is a retrospective cross-sectional study of children seen by pediatric ophthalmologists in an outpatient setting over 4 years. Primary outcomes were prevalence and causes of SCH, based on history, physical ocular and nonocular findings, and laboratory and imaging studies. Subconjunctival hemorrhage prevalence was determined including and excluding eye surgery to reduce bias in the prevalence estimate. RESULTS: We studied 33,990 children, who underwent 86,277 examinations (median age, 5 years; range, 2 days to 18 years; 9282 younger than 2 years, 13,447 age 2-7 years, 11,261 age 8-18 years). There were 949 cases of SCH (1.1%; 95% confidence interval, 1.0-1.2). When surgery was excluded, there were 313 cases (prevalence, 0.4%; 95% confidence interval, 0.3-0.4), of which 261 (83%) were due to trauma; 40 (13%) ocular surface inflammation, including infectious conjunctivitis; 7 (2%) orbital or conjunctival lesion; 3 (1%) vessel rupture from choking or cough; and 2 (1%) coagulopathy related. Across all ages, including less than 2 years, trauma and inflammation together accounted for 94% to 97% of all cases of SCH. CONCLUSIONS: Subconjunctival hemorrhage is uncommon in children. The great majority of cases are due to trauma. All children with SCH, including infants and young children, should be closely examined to identify other ocular or nonocular signs of trauma.

Debunking Fringe Beliefs in Child Abuse Imaging: AJR Expert Panel Narrative Review.

Child abuse is a global public health concern. Injuries from physical abuse may be clinically occult and not appreciable on physical examination. Imaging is therefore critical in identifying and documenting such injuries. The radiologic approach for a child who has potentially been abused has received considerable attention and recommendations according to decades of experience and rigorous scientific study. Nonetheless, fringe beliefs describing alternative explanations for child abuse-related injuries have emerged and received mainstream attention. Subsequently, imaging findings identified in abused children have been attributed to poorly supported underlying medical conditions, clouding the evidence basis for radiologic findings indicative of nonaccidental trauma. Fringe beliefs that attribute findings seen in child abuse to alternate pathologies such as genetic disorders, birth trauma, metabolic imbalances, vitamin D deficiency, and short-distance falls typically have limited evidence basis and lack professional society support. Careful review of the scientific evidence and professional society consensus statements is important in differentiating findings attributable to child abuse from fringe beliefs used to discount the possibility that a child's constellation of injuries is consistent with abuse. This review refutes fringe beliefs used to provide alternative explanations in cases of suspected child abuse and reinforces the key literature and scientific consensus regarding child abuse imaging.

Clinical evaluation and management of children with suspected physical abuse.

Evaluating and managing children with suspected physical abuse is challenging. Few single injuries are pathognomonic for abuse and, as a result, child abuse is easily missed. As such, a healthy bit of skepticism is needed to recognize and protect abused children. The medical history and clinical presentation should guide evaluation. Medical providers must consider the differential diagnosis, epidemiology of injuries, and child development to inform the assessment. In this review, we address evidence-based recommendations to inform child physical abuse evaluations. We also discuss the role of medical providers in communicating with families, mandated reporting and interpreting medical information for investigative agencies and other non-medical colleagues entrusted with protecting children.

Vitamin D, rickets and child abuse: controversies and evidence.

Suboptimal vitamin D status is a global health issue that affects children and adults worldwide. The prevalence of vitamin D deficiency and insufficiency has been well documented in the pediatric population in the United States. Although vitamin D deficiency is common, radiographic findings are uncommon and can be subtle. Additionally, because of the high prevalence of pediatric vitamin D insufficiency, it is commonly identified in young children with fractures. However, the majority of pediatric fractures are caused by trauma to healthy bones. Some, especially in infants and toddlers, are caused by non-accidental trauma. A small percentage is related to medical disease, including those associated with disorders of collagen, disorders of mineralization, and non-fracture mimics. Despite the scientific evidence, among disorders of mineralization, non-rachitic disorders of vitamin D have become a popular non-scientific theory to explain the fractures identified in abused children. Although infants and young children with rickets can fracture bones, the vast majority of fractures identified in abused infants are not caused by bone disease. Here we present a review of the literature on bone disease in the setting of accidental and non-accidental trauma. This context can help physicians remain vigilant about identifying vulnerable young children whose injuries are caused by non-accidental trauma.

Rachitic change and vitamin D status in young children with fractures.

OBJECTIVE: To examine the association between rachitic changes and vitamin D levels in children less than 2 years old with fractures. METHODS: Children less than 2 years old who were admitted to a large children's hospital for a fracture and underwent a skeletal survey were included. Two pediatric radiologists blinded to the children's vitamin D levels independently reviewed the skeletal surveys for the following rachitic findings: demineralization, widened sutures, rachitic rosary, Looser zones, and metaphyseal changes. Kappa coefficients were calculated to assess inter-rater agreement. Logistic regression was used to test the association between vitamin D level and rachitic findings. RESULTS: There were 79 subjects (40 female and 39 male) with a median age of 4 months. Vitamin D levels ranged from 11.6 to 88.9 ng/ml and were low in 27. Questionable demineralization was noted in seven subjects; mild to moderate demineralization was observed in four subjects. Widened sutures were noted in seven subjects, many also with concurrent intracranial hemorrhage. Lower vitamin D levels were associated with increased odds of demineralization after adjusting for age, gender, and prematurity (P < 0.015). An association was not found between the vitamin D level and suture widening (P = 0.07). None of the cases demonstrated Looser zones, rachitic rosary, or metaphyseal changes of rickets. CONCLUSIONS: Infants and toddlers with fractures frequently have suboptimal vitamin D levels, but radiographic evidence of rickets is uncommon in these children.

Infant skull fracture risk for low height falls.

Skull fractures are common injuries in young children, typically caused by accidental falls and child abuse. The paucity of detailed biomechanical data from real-world trauma in children has hampered development of biomechanical thresholds for skull fracture in infants. The objectives of this study were to identify biomechanical metrics to predict skull fracture, determine threshold values associated with fracture, and develop skull fracture risk curves for low-height falls in infants. To achieve these objectives, we utilized an integrated approach consisting of case evaluation, anthropomorphic reconstruction, and finite element simulation. Four biomechanical candidates for predicting skull fracture were identified (first principal stress, first principal strain, shear stress, and von Mises stress) and evaluated against well-witnessed falls in infants (0-6 months). Among the predictor candidates, first principal stress and strain correlated best with the occurrence of parietal skull fracture. The principal stress and strain thresholds associated with 50 and 95% probability of parietal skull fracture were 25.229 and 36.015 MPa and 0.0464 and 0.0699, respectively. Risk curves using these predictors determined that infant falls from 0.3 m had a low probability (0-54%) to result in parietal skull fracture, particularly with carpet impact (0-1%). Head-first falls from 0.9 m had a high probability of fracture (86-100%) for concrete impact and a moderate probability (34-81%) for carpet impact. Probabilities of fracture in 0.6 m falls were dependent on impact surface. Occipital impacts from 0.9 m onto the concrete also had the potential (27-90% probability) to generate parietal skull fracture. These data represent a multi-faceted biomechanical assessment of infant skull fracture risk and can assist in the differential diagnosis for head trauma in children.

Pneumatosis Intestinalis Due to Child Abuse.

Pneumatosis intestinalis (PI) and the presence of portal venous gas (PVG) are commonly considered pathognomonic for necrotizing enterocolitis in the neonatal period; however, these 2 radiographic findings have been documented in all age groups in a variety of clinical settings and medical conditions including respiratory, cardiac, rheumatologic, gastrointestinal disorders, and traumatic injury. In children, intramural dissection of intestinal gas in the absence of clinical symptoms suggestive of necrotizing enterocolitis should raise concern for a traumatic etiology, including injuries sustained from child physical abuse. Several pediatric cases of traumatic PI and PVG have been reported; however, these cases described additional, associated abdominal injury or featured toddlers - a single case report of accidental abdominal trauma resulted in PVG in a preterm infant. We report the case of a neonatal victim of child physical abuse presenting with PI and PVG in the absence of other evidence of abdominal trauma.

Prevalence of Abuse Among Young Children With Rib Fractures: A Systematic Review.

OBJECTIVES: We aimed to estimate the prevalence of abuse in young children presenting with rib fractures and to identify demographic, injury, and presentation-related characteristics that affect the probability that rib fractures are secondary to abuse. METHODS: We searched PubMed/MEDLINE and CINAHL databases for articles published in English between January 1, 1990, and June 30, 2014 on rib fracture etiology in children 5 years or younger. Two reviewers independently extracted predefined data elements and assigned quality ratings to included studies. Study-specific abuse prevalences and the sensitivities, specificities, and positive and negative likelihood ratios of patients' demographic and clinical characteristics for abuse were calculated with 95% confidence intervals. RESULTS: Data for 1396 children 48 months or younger with rib fractures were abstracted from 10 articles. Among infants younger than 12 months, abuse prevalence ranged from 67% to 82%, whereas children 12 to 23 and 24 to 35 months old had study-specific abuse prevalences of 29% and 28%, respectively. Age younger than 12 months was the only characteristic significantly associated with increased likelihood of abuse across multiple studies. Rib fracture location was not associated with likelihood of abuse. The retrospective design of the included studies and variations in ascertainment of cases, inclusion/exclusion criteria, and child abuse assessments prevented further meta-analysis. CONCLUSIONS: Abuse is the most common cause of rib fractures in infants younger than 12 months. Prospective studies with standardized methods are needed to improve accuracy in determining abuse prevalence among children with rib fractures and characteristics associated with abusive rib fractures.

Consensus statement on abusive head trauma in infants and young children.

Abusive head trauma (AHT) is the leading cause of fatal head injuries in children younger than 2 years. A multidisciplinary team bases this diagnosis on history, physical examination, imaging and laboratory findings. Because the etiology of the injury is multifactorial (shaking, shaking and impact, impact, etc.) the current best and inclusive term is AHT. There is no controversy concerning the medical validity of the existence of AHT, with multiple components including subdural hematoma, intracranial and spinal changes, complex retinal hemorrhages, and rib and other fractures that are inconsistent with the provided mechanism of trauma. The workup must exclude medical diseases that can mimic AHT. However, the courtroom has become a forum for speculative theories that cannot be reconciled with generally accepted medical literature. There is no reliable medical evidence that the following processes are causative in the constellation of injuries of AHT: cerebral sinovenous thrombosis, hypoxic-ischemic injury, lumbar puncture or dysphagic choking/vomiting. There is no substantiation, at a time remote from birth, that an asymptomatic birth-related subdural hemorrhage can result in rebleeding and sudden collapse. Further, a diagnosis of AHT is a medical conclusion, not a legal determination of the intent of the perpetrator or a diagnosis of murder. We hope that this consensus document reduces confusion by recommending to judges and jurors the tools necessary to distinguish genuine evidence-based opinions of the relevant medical community from legal arguments or etiological speculations that are unwarranted by the clinical findings, medical evidence and evidence-based literature.

Medical Mimics of Child Abuse.

OBJECTIVE: Physicians have an ethical and legal mandate to identify abused children so that they may be protected from further harm and are simultaneously required to think broadly and objectively about differential diagnoses. The medical literature is replete with examples of medical diseases that mimic abuse, potentially leading to misdiagnoses and subsequent harm to children and families. CONCLUSION: This review highlights some of the common and uncommon diseases that mimic physical and sexual abuse of children.

The etiology and significance of fractures in infants and young children: a critical multidisciplinary review.

This paper addresses significant misconceptions regarding the etiology of fractures in infants and young children in cases of suspected child abuse. This consensus statement, supported by the Child Abuse Committee and endorsed by the Board of Directors of the Society for Pediatric Radiology, synthesizes the relevant scientific data distinguishing clinical, radiologic and laboratory findings of metabolic disease from findings in abusive injury. This paper discusses medically established epidemiology and etiologies of childhood fractures in infants and young children. The authors also review the body of evidence on the role of vitamin D in bone health and the relationship between vitamin D and fractures. Finally, the authors discuss how courts should properly assess, use, and limit medical evidence and medical opinion testimony in criminal and civil child abuse cases to accomplish optimal care and protection of the children in these cases.

Sexual Assault and Sexually Transmitted Infections in Adults, Adolescents, and Children.

Survivors of sexual assault are at risk for acquiring sexually transmitted infections (STIs). We conducted literature reviews and invited experts to assist in updating the sexual assault section for the 2015 Centers for Disease Control and Prevention sexually transmitted diseases (STD) treatment guidelines. New recommendations for STI management among adult and adolescent sexual assault survivors include use of nucleic acid amplification tests (NAATs) for detection of Trichomonas vaginalis by vaginal swabs; NAATs for detection of Neisseria gonorrhoeae and Chlamydia trachomatis from pharyngeal and rectal specimens among patients with a history of exposure or suspected extragenital contact after sexual assault; empiric therapy for gonorrhea, chlamydia, and trichomoniasis based on updated treatment regimens; vaccinations for human papillomavirus (HPV) among previously unvaccinated patients aged 9-26 years; and consideration for human immunodeficiency virus (HIV) nonoccupational postexposure prophylaxis using an algorithm to assess the timing and characteristics of the exposure. For child sexual assault (CSA) survivors, recommendations include targeted diagnostic testing with increased use of NAATs when appropriate; routine follow-up visits within 6 months after the last known sexual abuse; and use of HPV vaccination in accordance with national immunization guidelines as a preventive measure in the post-sexual assault care setting. For CSA patients, NAATs are considered to be acceptable for identification of gonococcal and chlamydial infections from urine samples, but are not recommended for extragenital testing due to the potential detection of nongonococcal Neisseria species. Several research questions were identified regarding the prevalence, detection, and management of STI/HIV infections among adult, adolescent, and pediatric sexual assault survivors.

High-Fidelity Bleeding Control Simulation Scenario During Medical Student Orientation Improves Students' Self-Reported Ability to Identify and Treat Life-Threatening Bleeding with 3-year Follow-up.

OBJECTIVE: Increasingly, medical schools integrate clinical skills into early didactic coursework. The Stop the Bleed® Campaign emphasizes prehospital hemorrhage control to reduce preventable deaths; however, this course overlooks team interactions. We assessed the impact of high-fidelity simulation during medical student orientation on identification and treatment of life-threatening hemorrhage in a team setting. DESIGN: In this mixed method, prospective pre-, post-, and follow-up survey analysis assessing student knowledge and attitudes, student teams encountered a standardized patient in a prehospital environment with pulsatile bleeding from an extremity wound. Individual students completed surveys assessing previous experience, willingness and ability to assist bleeding person(s), and knowledge and attitudes about tourniquets. Postscenario, faculty preceptors made qualitative observations on teamwork. SETTING: Medical student orientation at a tertiary care academic medical center with long-term follow-up. PARTICIPANTS: Medical students (N = 150). RESULTS: Ninety students (60%) completed both pre- and postsimulation questionnaires. Sixteen (17%) students had previous tourniquet training experience although none had applied a tourniquet outside of training. Postsimulation, students reported increased likelihood of providing treatment until additional help arrived (p = 0.035), improved ability to identify life-threatening hemorrhage (p < 0.001), and more favorable opinions about tourniquet use (p < 0.001) and potential for limb-salvage (p = 0.018). Long-term follow-up respondents (n = 34, 23%) reported increased ability to identify life-threatening hemorrhage (p = 0.010) and universal willingness to intervene until additional help arrived. Follow-up survey responses elicited themes in hemorrhage control including recognition of the importance of continuous pressure, appropriate use of tourniquets, a desire for repeated team training, and the recognition of clerkship rotations as an optimal setting for skill reinforcement. Preceptors noted variable team responses but uniformly endorsed the exercise. CONCLUSIONS: High-fidelity bleeding simulation during medical student orientation improved students' knowledge and attitudes about treating life-threatening hemorrhage and served as an introduction to team-based emergency care. Future studies should further explore team training and hemorrhage control education.

Nonconvulsive electrographic seizures are common in children with abusive head trauma*.

OBJECTIVE: To determine the prevalence of nonconvulsive seizures in children with abusive head trauma. DESIGN: Retrospective study of children with abusive head trauma undergoing clinically indicated continuous electroencephalographic monitoring. SETTING: PICU of a tertiary care hospital. SUBJECTS: Children less than or equal to 2 years old with evidence of abusive head trauma determined by neuroimaging, physical examination, and determination of abuse by the Child Protection Team. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Thirty-two children with abusive head trauma were identified with a median age of 4 months (interquartile range 3, 5.5 months). Twenty-one of 32 children (66%) underwent electroencephalographic monitoring. Those monitored were more likely to have a lower admission Glasgow Coma Scale (8 vs 15, p = 0.05) and be intubated (16 vs 2, p = 0.002). Electrographic seizures occurred in 12 of 21 children (57%) and constituted electrographic status epilepticus in 8 of 12 children (67%). Electrographic seizures were entirely nonconvulsive in 8 of 12 children (67%). Electroencephalographic background category (discontinuous and slow-disorganized) (p = 0.02) and neuroimaging evidence of ischemia were associated with the presence of electrographic seizures (p = 0.05). Subjects who had electrographic seizures were no more likely to have clinical seizures at admission (67% electrographic seizures vs 33% none, p = 0.6), parenchymal imaging abnormalities (61% electrographic seizures vs 39% none, p = 0.40), or extra-axial imaging abnormalities (56% electrographic seizures vs 44% none, p = 0.72). Four of 21 (19%) children died prior to discharge; none had electrographic seizures, but all had attenuated-featureless electroencephalographic backgrounds. Follow-up outcome data were available for 16 of 17 survivors at a median duration of 9.5 months following PICU admission, and the presence of electrographic seizures or electrographic status epilepticus was not associated with the Glasgow Outcome Scale score (p = 0.10). CONCLUSIONS: Electrographic seizures and electrographic status epilepticus are common in children with abusive head trauma. Most seizures have no clinical correlate. Further study is needed to determine whether seizure identification and management improves outcome.

Enhancing the emergency department approach to pediatric sexual assault care: implementation of a pediatric sexual assault response team program.

OBJECTIVES: The objectives of this study were to describe the experience of a novel pediatric sexual assault response team (SART) program in the first 3 years of implementation and compare patient characteristics, evaluation, and treatment among subpopulations of patients. METHODS: This was a retrospective chart review of a consecutive sample of patients evaluated at a pediatric emergency department (ED) who met institutional criteria for a SART evaluation. Associations of evaluation and treatment with sex, menarchal status, and presence of injuries were measured using logistic regression. RESULTS: One hundred eighty-four patients met criteria for SART evaluation, of whom 87.5% were female; mean age was 10.1 (SD, 4.6) years. The majority of patients underwent forensic evidence collection (89.1%), which varied by menarchal status among girls (P < 0.01), but not by sex. Evidence of acute anogenital injury on physical examination was found in 20.6% of patients. As per the Centers for Disease Control and Prevention guidelines for acute sexual assault evaluations in pediatric patients, menarchal girls were more likely to undergo testing for sexually transmitted infections and pregnancy (P < 0.01) and to be offered pregnancy, sexually transmitted infection, and HIV prophylaxis (P < 0.01). CONCLUSIONS: In an effort to improve quality and consistency of acute sexual assault examinations in a pediatric ED, development of a SART program supported the majority of eligible patients undergoing forensic evidence collection. Furthermore, a substantial number of patients had evidence of injury on examination. These findings underscore the importance of having properly trained personnel to support ED care for pediatric victims of acute sexual assault.
