Infant abusive head trauma

In death investigations, the volume of gastric contents may be useful concerning the time of death estimation, or to clarify the circumstances of death. Here, the case of a 4-month-old male infant who was found dead in his mother's bed is presented. SIDS was assumed as the cause of death after initial police investigations. Later, autopsy results revealed that this case was a homicide due to extensive abusive head trauma. The infant had three skull fractures on the back of his head with subdural hemorrhage and cerebral oedema...

BACKGROUND: Abusive head trauma (AHT) is a major cause of traumatic brain injury in infancy. This exploratory study compared standardized developmental assessment versus functional outcome assessment between 18 months and 5 years of age following AHT in infancy. METHODS: Observational cross-sectional study after surviving AHT in infancy. Seventeen children between 18 months and 5 years of age underwent clinical examination, developmental assessment using the Schedule of Growing Skills II (SGS II) and functional assessment using the Glasgow Outcome Scale-Extended Pediatric Revision (GOS-E Peds)...

PURPOSE: Infantile acute subdural hematoma (IASDH) has a limited age distribution and mostly benign clinical features. Mild-type IASDH has a stereotypical clinical course which, however, has been described in only a few studies. METHODS: Four male infants (aged 6-10 months; mean age: 7.5 months) were diagnosed as mild-type IASDH associated with retinal hemorrhage (RH) after suffering from occipital impact in a fall. The present case series reviews their clinical features and neuroimaging findings, including CT and MRI findings...

Subdural hemorrhages (SDHs) in children are most often observed in abusive head trauma (AHT), a distinct form of traumatic brain injury, but they may occur in other conditions as well, typically with clear signs and symptoms of an alternative diagnosis. We present a case of an infant whose SDH initially raised the question of AHT, but multidisciplinary evaluation identified multiple abnormalities, including rash, macrocephaly, growth failure, and elevated inflammatory markers, which were all atypical for trauma...

BACKGROUND: Although there is research regarding the diagnosis and timing of abusive head trauma, there remains practice variation among pediatric subspecialists. OBJECTIVES: To examine diagnostic variability among pediatric subspecialists using case examples of infant head injury. Secondary objectives were timing variability among subspecialists, and diagnostic and timing variability among Child Abuse Pediatricians (CAPs). PARTICIPANTS AND SETTING: Pediatric subspecialists were recruited from Child Abuse Pediatrics, Hospital Medicine, Emergency Medicine, Critical Care, and Neurosurgery to complete a research instrument...

Abusive head trauma in infants is a consequence of multiple episodes of abuse and results in axonal injury, brain atrophy, and chronic cognitive deficits. Anesthetized 11-day-old rats, neurologically equivalent to infants, were subjected to 1 impact/day to the intact skull for 3 successive days. Repeated, but not single impact(s) resulted in spatial learning deficits (p < 0.05 compared to sham-injured animals) up to 5 weeks postinjury. In the first week following single or repetitive brain injury, axonal and neuronal degeneration, and microglial activation were observed in the cortex, white matter, thalamus, and subiculum; the extent of the histopathologic damage was significantly greater in the repetitive-injured animals compared to single-injured animals...

Infant cry is an adaptive signal of distress that elicits timely and mostly appropriate caring behaviors. Caregivers are typically able to decode the meaning of the cry and respond appropriately, but maladaptive caregiver responses are common and, in the worst cases, can lead to harmful events. To tackle the importance of studying cry patterns and caregivers' responses, this review aims to identify key documents and thematic trends in the literature as well as existing research gaps. To do so, we conducted a scientometric review of 723 documents downloaded from Scopus and performed a document co-citation analysis...

BACKGROUND: Child abuse represents an important issue in the medico-legal and social context. In the last few decades, various aspects and mechanisms have been identified in child abuse case studies; however, constant research is needed in the field. With this paper, the authors will present a case of a new entity of Abusive Head Trauma that has come to the attention of medico-legal experts. DISCUSSION: The trauma analysis performed on the cranio-encephalic district of the baby revealed quite peculiar lesions that led the authors to exclude that the injuries had been solely caused by violent shaking of the baby's head, as suggested by Shaken Baby Syndrome ...

The shaken baby syndrome was originally proposed in the 1970s without any formal scientific basis. Once data generated by scientific research was available, the hypothesis became controversial. There developed essentially two sides in the debate. One side claimed that the clinical triad of subdural haemorrhage, retinal haemorrhage, and encephalopathy, or its components, is evidence that an infant has been shaken. The other side stated this is not a scientifically valid proposal and that alternative causes, such as low falls and natural diseases, should be considered...

Abusive head trauma (AHT) is a significant cause of morbidity and mortality for infants. Determining when to pursue a complete physical abuse evaluation can be difficult, especially for nonspecific findings or when a child appears clinically well. This retrospective study of 7 cases sought to describe the presentation, evaluation, and diagnoses for infants with abnormal subdural collections identified on cranial ultrasound for macrocephaly, and to determine how frequently AHT is diagnosed. The results of this study showed that while each patient presented due to asymptomatic macrocephaly, the extent of the workup varied greatly...

BACKGROUND: Abusive head trauma (AHT) is the leading cause of death in infants with traumatic brain injury (TBI). Early recognition of AHT is important for improving outcomes, but it can be challenging due to its similar presentations with non-abusive head trauma (nAHT). This study aims to compare clinical presentations and outcomes between infants with AHT and nAHT, and to identify the risk factors for poor outcomes of AHT. METHODS: We retrospectively analyzed infants of TBI in our pediatric intensive care unit from January 2014 to December 2020...

Early neurobehavioral outcomes among infants with abusive head trauma (AHT) have not been well characterized. Though there are standardized measures for assessing infants, the ability of these measures to detect deficits may be limited. The Neonatal Intensive Care Unit (NICU) Network Neurobehavioral Scale, Second Edition (NNNS-II) has been correlated with neurobehavioral outcomes as early as birth but has not been used with this clinical group. There is no strong evidence of the concurrent validity of this measure...

METHODS: Records and imaging were reviewed for children younger than 6 years, hospitalized between 2015 and 2020 for major closed head injuries following less than 4-ft falls. Major injury was defined as intensive care admission more than 2 days, neurosurgical intervention, death, or disability at hospital discharge. Subjects were identified through Seattle and Spokane, Washington abuse consultations. Harborview Medical Center's trauma registry and Seattle Children's Hospital's Hemophilia Treatment Program and Radiology were searched for subjects...

Abusive head trauma is the leading cause of physical child abuse deaths in children under 5 years of age in the United States. To evaluate suspected child abuse, radiologic studies are typically the first to identify hallmark findings of abusive head trauma including intracranial hemorrhage, cerebral edema, and ischemic injury. Prompt evaluation and diagnosis are necessary as findings may change rapidly. Current imaging recommendations include brain magnetic resonance imaging with the addition of a susceptibility weighted imaging (SWI) sequence which can detect additional findings that suggest abusive head trauma including cortical venous injury and retinal hemorrhages...

Subdural hemorrhages (SDHs) in the pediatric population are associated with a high mortality and morbidity and may present in the context of abusive head trauma. Diagnostic investigations for such cases often include evaluation for rare genetic and metabolic disorders that can have associated SDH. Sotos syndrome is an overgrowth syndrome associated with macrocephaly and increased subarachnoid spaces and rarely with neurovascular complications. Here, we report two cases of Sotos syndrome, one with SDH during infancy who underwent repeated evaluation for suspected child abuse prior to the Sotos syndrome diagnosis and the other with enlarged extra-axial cerebrospinal fluid spaces, demonstrating a possible mechanism for SDH development in this setting...

Abusive head trauma (AHT) is a serious traumatic brain injury and the leading cause of death in children younger than 2 years. The development of experimental animal models to simulate clinical AHT cases is challenging. Several animal models have been designed to mimic the pathophysiological and behavioral changes in pediatric AHT, ranging from lissencephalic rodents to gyrencephalic piglets, lambs, and non-human primates. These models can provide helpful information for AHT, but many studies utilizing them lack consistent and rigorous characterization of brain changes and have low reproducibility of the inflicted trauma...

In infants without a history of trauma, subdural haemorrhages should raise the concern for an abusive head injury, particularly when they are associated with bridging vein clotting/rupture or with septations. However, non-haemorrhagic, fluid-appearing subdural collections (also called hygromas) may also be the result of abuse. Subdural collections have also been uncommonly observed in patients with benign enlargement of the subarachnoid spaces (BESS) and a few large-scale studies accurately investigate the incidence and the significance...

Interleukin-1 receptor-associated kinase 4 (IRAK-4) deficiency is a primary immune deficiency of the innate immune system. Children with this condition are susceptible to life-threatening bacterial infections. IRAK-4 deficiency results in reduced or absent systemic features of inflammation despite overwhelming infection. We present 2 siblings who died in infancy after rapidly progressive Pseudomonas sepsis and meningitis. There was diagnostic uncertainty in the firstborn infant because of significant intracranial hemorrhages...

Parenting programs are the most common intervention for preventing the lethal form of child maltreatment, abusive head trauma (AHT). However, certain results of the effects of these programs have not yet been compared across studies. A systematic review with meta-analysis is warranted to quantitively synthesize the available evidence to identify effective elements and strategies of the programs for preventing AHT. This review aims to estimate AHT preventive parenting programs' pooled effect on the reduction of AHT incidence, the improvement of parental knowledge, and the increased use of safe strategies in response to infants' inconsolable crying...

We evaluated an infant with flagrantly abusive injury. However, he had a history of prior isolated ear hematoma that was not properly recognized as a sign of trauma, harshly illustrating a missed opportunity when early diagnosis may have prevented escalating abusive injury. In addition, we reviewed and summarized the last two decades of literature related to this topic to better understand previously described findings in similar populations; these were scant. This case report emphasizes the importance of detecting sentinel injuries that forebode child maltreatment...
