Diagnosing physical child abuse: the way forward

Finite element modelling of the developing infant femur using paired CT and MRI scans

Bone finite element (FE) studies based on infant post-mortem computed tomography (CT) examinations are being developed to provide quantitative information to assist the differentiation between accidental and inflicted injury, and unsuspected underlying disease. As the growing skeleton contains non-ossified cartilaginous regions at the epiphyses, which are not well characterised on CT examinations, it is difficult to evaluate the mechanical behaviour of the developing whole bone. This study made use of paired paediatric post mortem femoral CT and magnetic resonance imaging (MRI) examinations at two different stages of development (4 and 7 months) to provide anatomical and constitutive information for both hard and soft tissues. The work aimed to evaluate the effect of epiphyseal ossification on the propensity to shaft fractures in infants. The outcomes suggest that the failure load of the femoral diaphysis in the models incorporating the non-ossified epiphysis is within the range of bone-only FE models. There may however be an effect on the metaphysis. Confirmation of these findings is required in a larger cohort of children.

Do abused young children feel less pain?

The objective of this study was to investigate whether acute pain in abused children was under recognized by doctors and nurses compared to children evaluated for accidental injuries. We hypothesize that an abused child's reaction to physical pain could be an additional symptom of this challenging diagnosis. For the observational prospective case control study in an emergency department, children were eligible when: younger than six years old, the reported trauma occurred within the previous seven days, the trauma comprised a bone injury or burn, and the child was able to express his or her pain. The case group comprised children for whom the medical team reported their abuse suspicions and supporting information to a court, and whose cases of abuse were subsequently confirmed. The control group consisted of children with a plausible cause for their injury and no obvious signs of abuse. The children were matched according to their age and type of trauma. The pain was assessed by doctors and nurses before analgesic administration using a certified pain scale. Among the 78 included children, pain was significantly less recognized in the abused children vs. the controls (relative risk=0.63; 95% CI: 0.402-0.986; p=0.04). We observed a discrepancy between the nurses' and doctors' scores for the pain assessments (Kappa coefficient=0.59, 95% CI: 0.40-0.77). Our results demonstrate that pain expression in abused children is under recognized by medical staff. They also suggest that abused children may have reduced pain expression after a traumatic event. Paying particular attention to the pain of abused children may also optimize the analgesic treatment.

Cutaneous signs of child abuse

Maltreatment of children is a major public health crisis, and it is estimated that each year more than 3 million children are victims of abuse. Safeguarding the welfare of children is a priority, and it is the moral and ethical responsibility of healthcare professionals to detect cases of abuse and intervene appropriately to prevent further harm. Clinicians are often challenged to differentiate signs of child abuse from skin conditions that mimic maltreatment. Because cutaneous injury represents the most recognizable and common form of abuse, dermatologists are often called upon to help distinguish signs of intentional injury from skin conditions that mimic maltreatment. However, few resources specific to dermatologic signs of abuse exist to aid in diagnosis. A review of the literature will provide an educational resource to assist dermatologists and other clinicians in differentiating cutaneous signs of child abuse, including physical and sexual abuse, from mimickers of inflicted injury.

LEARNING OBJECTIVE

After completing this learning activity, participants should be able to distinguish signs of intentional injury from skin conditions that mimic maltreatment and understand the clinician's role in the diagnosis and reporting of cases of suspected child abuse.

Identifying non-accidental injury in children presenting to A&E departments: An overview of the literature

BACKGROUND

The need for an effective system of child protection, which is able to detect children at risk of physical abuse, has never been more urgent. The level of reporting of non-accidental injury (NAI) in young children is lower than would be expected from official statistics, which means that Accident and Emergency (A and E) nurses and clinicians have a special responsibility to improve detection of possible abuse, in what has become a very challenging area of medicine.

AIMS

In this paper, we review the main issues facing clinicians and nurses in the identification of children at risk of NAI and discuss the policy implications affecting A and E departments. In particular we ask the question: what are the factors that influence the identification and reporting of suspected NAI in young children and how can the under-recognition of NAI be improved?

CONCLUSION

We conclude that organisational changes, such as the creation of a shared national database and improved training for A and E staff so that they are aware of social as well as clinical risk factors, are needed to address the under-reporting of non-accidental injury in young children.
