Fatal intracranial hemorrhage due to infantile acute lymphoblastic leukemia mimicking abusive head trauma

Clinical and Forensic Investigation Protocols for Diagnosing Abusive Head Trauma: A Literature Review

Abusive head trauma (AHT) represents a very serious global public health problem. Prevention of these episodes is essential to reduce the morbidity and mortality of this phenomenon. All healthcare professionals should be able to recognize the signs of abuse. However, diagnosis is very complex as the signs are often blurred and cannot be recognized with certainty without carrying out adequate instrumental investigations. It has been calculated that approximately one-third of AHT cases remain undetected and require more than one medical visit to be correctly interpreted and diagnosed. On the other hand, the literature has recently also emphasized the problems related to possible false diagnoses of abuse and the numerous family and personal repercussions that follow from this issue. For these reasons, correct and timely recognition is essential to avoid the risk of recurrence of AHT and to start proper forensic investigations, in order to identify the offender or exonerate a suspect. The present work explores the most recent evidence of recent years in the field of AHT diagnostics through a literature review. The purpose of this article is to provide forensic pathologists with clear tools for diagnosis based on the literature. To this end, the review suggests clinical and forensic protocols aimed at the timely diagnosis of AHT in order to prevent abuse from remaining undetected.

The Eyes Have It: How Critical are Ophthalmic Findings to the Diagnosis of Pediatric Abusive Head Trauma?

Pediatric abusive head trauma (AHT), still colloquially known as shaken baby syndrome, is a leading cause of morbidity and mortality among infants. Controversy has grown surrounding this diagnosis, and the specificity of the clinical findings-subdural hemorrhage, cerebral edema, and retinal hemorrhages-has been challenged. A literature search of peer reviewed publications on PubMed pertaining to the history, clinical, and pathologic features of AHT was conducted using the terms "shaken baby syndrome," "non-accidental trauma," "abusive head trauma," "inflicted traumatic brain injury," "shaken impact syndrome," and "whiplash shaken infant syndrome." Focus was placed on articles discussing ophthalmic findings in AHT. Retinal hemorrhages-particularly those that are too numerous to count, occurring in all layers of the retina (preretinal, intraretinal, subretinal), covering the peripheral pole and extending to the ora serrata, and accompanied by retinoschisis and other ocular/periocular hemorrhages-are highly suggestive of AHT, particularly in the absence of otherwise explained massive accidental trauma. Although the diagnosis has grown in controversy in recent years, AHT has well-documented clinical and pathologic findings across a large number of studies.

Non-accidental head injury of infants: legal implications for the pediatric neurosurgeon

BACKGROUND

Though the neurosurgeon's role in non-accidental head injury (NAHT) is the prompt recognition and care of the inflicted injuries, he/she should be aware of the possible legal implications related to this particular neurosurgical condition.

MATERIAL AND METHODS

Based on published data and their own clinical and medico-legal practice, the authors review the role of the neurosurgeon in NHAT.

RESULTS

Besides the contribution that can be given by the neurosurgeon to a correct differential diagnosis, he/she is likely to be involved in the interpretations of the pathological findings in the case where the judge may request for a medical opinion concerning etiology, circumstances, severity, and consequences. As a member of a multidisciplinary team, usually the neurosurgeon is only requested for information regarding the lesions he was called to recognize and treat. Nevertheless, such information may have a pivotal part in the evaluation process. Consequently, the neurosurgeon should be able to reach a correct differential diagnosis of NAHT among all the events that may share similar clinical and anatomo-pathological characteristics and be aware of the ongoing scientific controversies related to the diagnosis and pathophysiology.

CONCLUSIONS

In practical terms, the pediatric neurosurgeon is called to individuate and record all the precise details of the condition to be eventually offered to the judge in case of controversy. Whereas the diagnosis of NAHT should be evoked at the initial phase in order not to leave the child unprotected, all possible alternative hypotheses should be ruled out "beyond reasonable doubt" for the court. The medical file should be maintained in the record carefully and be accessible even after a long time.
