Understanding Bilateral Skull Fractures in Infancy: A Retrospective Multicenter Case Review.

BACKGROUND: Bilateral skull fractures in infancy often raise suspicion for abuse. Nevertheless, literature suggests that they may occur accidentally. However, empiric data are lacking. OBJECTIVE: This multicenter retrospective review aimed to characterize bilateral skull fractures in a large sample. PARTICIPANTS AND SETTING: Medical records for infants younger than 24 months with bilateral skull fractures involving hospital consultation with a child abuse pediatrician (CAP) were reviewed from 2005 to 2020 at 13 nationally represented institutions. METHODS: Standardized data collection across institutions included historical features, fracture characteristics, and additional injuries, as well as the CAP's determination of accident versus abuse. Pooled data were analyzed for descriptive and bivariate analyses. RESULTS: For 235 cases, 141 were accidental, and 94 abuse. The majority occurred in young infants, and a history of a fall was common in 70% of cases. More than 80% involved both parietal bones. Bilateral simple linear fractures were more common in accidental cases, 79% versus 35%, whereas a complex fracture was more frequent in abuse cases, 55% versus 21% ( P < 0.001). Almost two thirds of accidental cases showed approximation of the fractures at the sagittal suture, compared with one third of abuse cases ( P < 0.001). Whereas focal intracranial hemorrhage was seen in 43% of all cases, diffuse intracranial hemorrhage was seen more in abuse cases (45%) than accidents (11%). Skin trauma was more common in abusive than accidental injury (67% vs 17%, P < 0.001), as were additional fractures on skeletal survey (49% vs 3%, P < 0.001). CONCLUSIONS: A fall history was common in bilateral skull fractures deemed accidental by a CAP. Most accidental cases involved young infants with biparietal simple linear fractures, without skin trauma or additional fractures. A skeletal survey may aid in the determination of accidental or abusive injury for unwitnessed events resulting in bilateral skull fractures in infants.

Pathogenic variant in NFIA associated with subdural hematomas mimicking nonaccidental trauma.

Subdural hematoma (SDH) in infants raises the concern for nonaccidental trauma (NAT), especially when presenting with associated injuries. However, isolated SDH could be caused by multiple etiologies. NFIA (MIM# 600727) encodes nuclear factor I A protein (NFI-A), a transcription factor which plays important roles in gliogenesis. Loss-of-function variants in NFIA are associated with autosomal dominant brain malformations with or without urinary tract defects (MIM# 613735). Intracranial hemorrhage of various types besides SDH has been reported in patients with this condition. Here, we report a patient with a heterozygous novel NFIA pathogenic variant affecting splicing who initially presented with SDH concerning for NAT. We also review previous NFIA-related disorder cases with intracranial hemorrhage. This report emphasizes the importance of genetic evaluation in infants presenting with isolated SDH.

Missed Fractures in Infants Presenting to the Emergency Department With Fussiness.

OBJECTIVES: The aim of this study was to evaluate incidence of prior fussy emergency visits in infants with subsequently diagnosed fractures suggestive of abuse. METHODS: This was a retrospective chart review of infants younger than 6 months who presented to the pediatric emergency department (ED) between January 1, 2006, and December 31, 2011. Inclusion criteria included age 0 to 6 months, discharge diagnosis including "fracture," "broken" (or break), or "trauma" or any child abuse diagnosis or chief complaint of "fussy" or "crying" as documented in the electronic medical record by the triage nurse. RESULTS: Three thousand seven hundred thirty-two charts were reviewed, and 279 infants with fractures were identified. Eighteen (6.5%) of 279 infants had a prior ED visit for fussiness without an obvious source. Of these, 2 had a witnessed event causing their fracture, and therefore the fracture was not considered concerning for abuse. The remaining 16 had fractures concerning for abuse. Mean age was 2.5 (SD, 1.2) months. Fifteen (83%) of 18 infants were 3 months or younger at the time of the fussy visit. The mean interval between the first and second ED visits was 27 days (median, 20 days). Thirty-nine percent were evaluated by a pediatric emergency medicine-trained physician during their initial fussy visit, whereas 78% were evaluated by pediatric emergency medicine-trained physician during their subsequent visit. Most common injuries were multiple types of fractures followed by extremity and rib fractures. CONCLUSIONS: Fractures concerning for child abuse are an important cause of unexplained fussiness in infants presenting to the pediatric ED. A high index of suspicion is essential for prompt diagnosis and likely prevention of other abuse.

The Relationship Between Temperature and Temporal Patterns and Incidence of Abusive Head Trauma in a Midwest Region Hospital.

Background: Abusive head trauma (AHT) is a leading cause of death and disability in children and one of the most lethal forms of child abuse. Most known risk factors for AHT pertain to the infant's caregiver and limited research has assessed external influences beyond the familial or caregiver/infant dyad. Objective: Our primary objective was to determine if temperature patterns are associated with AHT events. Secondary outcomes included associations between AHT and specific days of the week, months, or seasons. Methods: This was a retrospective review of 198 patients under 24 months old who were diagnosed with AHT at Saint Louis Children's Hospital. Demographic information was obtained from the medical record for each patient. For each AHT incident, the date and zip code of the incident were recorded. Temperature on the date of incident was identified using the Midwestern Regional Climate Center (MRCC). Chi square tests were utilized to calculate differences in cases per year as well as temperature and seasonal variation. Results: Temperature was not associated with a statistically significant increase in cases of AHT. There was an increase in cases as temperatures rose, but no statistically significant associations between incidence of AHT and day of the week, month, or season. Conclusion: Our study suggests no significant association between AHT incidence and temperature or temporal patterns in this Midwest hospital.

Emergency Department Admissions for Physical Child Abuse: Evidence from the 2006-2017 Nationwide Emergency Department Sample.

Physical child abuse continues to be a serious public health issue in the United States. This study expands on previous research by exploring trends in physical child abuse diagnoses among children admitted to emergency departments (EDs) across the United States. The analysis aimed to explicate the association between physical child abuse and both sociodemographic and behavioral health covariates to better inform and identify risk factors associated with ED admissions for abuse. The study also explicated differences between confirmed and suspected physical child abuse cases. The study utilized a nationally representative sample of hospital-owned EDs that included 319,676,625 ED admissions between 2006 and 2017 for children under 18-years-old. The analysis included a trend analysis, bivariate descriptive statistics, and multivariate logistic regression models were employed. Children with a physical child abuse diagnosis were less likely to be from higher income communities (aOR = 0.61, 95% CI [0.53, 0.71]), less likely to be female (aOR = 0.93, 95% CI [0.90, 0.96]), and more likely to be uninsured (aOR = 1.65, 95% CI [1.48, 1.84]). Children with attention-deficit hyperactivity disorder (aOR = 1.36, 95% CI [1.14, 1.62]) and a conduct disorder (aOR = 1.28, 95% CI [1.04, 1.58]) were more likely to have a physical abuse diagnosis. The sex-stratified analyses found that the higher rates of physical abuse among children with attention-deficit hyperactivity disorder were driven by the male subsample, while higher rates of abuse for those with conduct disorders were the result of the female subsample. A supplemental analysis of suspected versus confirmed physical child abuse for the fourth quarter of 2015 through 2017 also revealed sociodemographic and behavioral health differences. This study supports the need to consider sociodemographic and behavioral risk factors associated with physical child abuse to inform treatment and potential reoccurrence of abuse.

Discordance in Reporting of Maternal Aggression: Exploring Differences by Characteristics of Children, Mothers, and Their Environments.

This study investigated discordant reports of maternal aggression using the Fragile Families and Child Wellbeing Study (N = 1,606). Multinomial logistic regression models predicted discordant reports of hitting and shouting from child, mother, and environmental characteristics. Compared to dyads in which both mothers and children reported aggression, mothers with a college degree had higher child-only and mother-only reports of both hitting and shouting versus mothers with less than a high school diploma. High-income mothers had higher child-only reports of hitting, while families with past Child Protective Services involvement had higher child-only and mother-only reports of hitting. Additionally, children with lower reading test scores and whose fathers had history of incarceration had higher child-only reports of hitting. Families residing in neighborhoods for which mothers were scared to let children play outside also had higher child-only and mother-only reports of hitting and shouting.
