Fatal acute intracranial injury, subdural hematoma, and retinal hemorrhages caused by stairway fall

We describe an infant with an acute subdural hematoma, a fatal head injury, and severe hemorrhagic retinopathy caused by a stairway fall. His cerebral and ocular findings are considered diagnostic of abusive head trauma by many authors. Our literature search of serious injuries or fatalities from stairway or low-height falls involving young children yielded 19 articles of primary data. These articles are discrepant, making the classification of a young child's death following a reported short fall problematic. This case report contradicts the prevalent belief of many physicians dealing with suspected child abuse that low-height falls by young children are without exception benign occurrences and cannot cause fatal intracranial injuries and severe retinal hemorrhages. The irreparable harm to a caregiver facing an erroneous allegation of child abuse requires physicians to thoroughly investigate and correctly classify pediatric accidental head injuries.     

Are Peripapillary Intrascleral Hemorrhages Pathognomonic for Abusive Head Trauma?*

Abstract: The American Academy of Pediatrics’ Committee on Child Abuse and Neglect, Section on Ophthalmology, acknowledges that searching for retinal hemorrhages (RHs) in infants only in cases of suspected of abuse creates selection bias. However, they also recommend that postmortem eye removal might not be indicated “in children who have clearly died from witnessed severe accidental head trauma or otherwise readily diagnosed systemic medical conditions.” Although infrequently described in the child abuse literature, peripapillary intrascleral hemorrhages (bleeding in the sclera at the optic nerve insertion)—putatively from severe repetitive acceleration/deceleration forces with or without blunt head trauma—have been considered essentially pathognomonic for abusive head trauma (shaken baby syndrome). We present two neonates who sustained accidental, severe in utero head injuries and had associated extensive RHs and optic nerve sheath hemorrhages with peripapillary intrascleral hemorrhages detected at autopsy. Neither neonate had a documented clinical fundal examination in the intensive care unit.     

Cerebral traumatism with a playground rocking toy mimicking shaken baby syndrome

Shaken baby syndrome (SBS), one of the most deadly and devastating forms of child abuse, is caused by violent shaking. The combination of subdural hematoma, retinal hemorrhage, brain swelling, and diffuse axonal injury is highly typical of this syndrome and faced with these autopsy findings, induced traumatic lesions are strongly considered. However, it is known that motor-vehicle accidents and falls from great height can also produce this pattern of injury. Nevertheless, stories of arms fall, couch fall, or bumped head while the baby is being carried are generally considered incompatible with SBS. We here report a case of a 2-year-old boy presenting with all the classic autopsy findings of SBS from a playground rocking toy shaken by an older child.     

Disseminated neonatal herpetic infection simulating abusive anal trauma

Potential simulators of premortem trauma present problems of misinterpretation and possible false accusations of caregivers. A case of unsuspected neonatal herpes is reported with associated perianal ecchymosis that raises the possibility of sexual abuse. The decedent was an 8-day-old newborn infant who was born by Cesarean section and treated for 5 days postdelivery for sepsis. The newborn infant was discharged home but returned 2 days later with probable sepsis and new onset of perianal hemorrhage. She died 1 day later with autopsy, revealing neonatal disseminated herpetic infection with early anal involvement consisting of microscopic ulcerations with leukocytoclastic-like vasculitis and rare viral cytopathic changes. These histological changes produced grossly appearing anal ecchymosis with an absence of typical herpetic vesiculopapular lesions, which simulated abusive trauma. This case highlights the importance of considering occult neonatal herpes with associated perianal ecchymosis when presented with possible abusive anal trauma in a newborn infant.     

TV tip-over morbidity and mortality in children

Twenty-eight non-fatal cases of TV related injuries were noted in San Diego in the 2 years prior to September 2008. We reviewed the scene, witness reports, past history, and autopsy findings from three fatal cases and distinguished them from abusive head trauma. The recent literature was also reviewed. Our fatal cases resulted from TVs falling on small children and causing severe head injury. The literature review showed increasing injuries and deaths relating to TV tip-over, TV stands and dressers. Most of the fatalities were head injuries in small children. The reporting methods may not be complete or accurate. Some authors in the literature review suggested preventive measures so as to decrease these injuries. Forensic scientists should become familiar with these injuries and measures so that they may communicate effectively with their communities.     

Ocular findings in pediatric deaths under 2 years of age (1994-2004)

Abstract:  Our purpose is to highlight novel ocular findings of 102 forensic pediatric cases under 2 years of age who die suddenly. Forensic information, grossing, and microscopic eye protocol was followed. The most common diagnosis was Sudden Infant Death Syndrome (SIDS) (57/102). Novel cytoid bodies were present in the retina of 72/102 cases and they were located predominantly 90% (65/72) at the anterior part of the retina ( p  < 0.001). Of the SIDS cases, 85% (47/57) showed the presence of cytoid bodies, and among all diagnosis, SIDS was the most associated with cytoid bodies ( p  = 0.003). A second observation was extramedullary hematopoiesis (EMH) identified in 35/102 cases and 22 of the 57 SIDS cases. The most frequent EMH location was the choroids (29/35). This study is the first to demonstrate the presence of cytoid bodies and extramedullary hematopoiesis in the retinas of SIDS cases and children who die suddenly from other causes.

Discrimination of falls and blows in blunt head trauma: systematic study of the hat brim line rule in relation to skull fractures

In the discrimination of falls from blows in blunt head trauma, the hat brim line rule is one of the most often used criteria. The present study assesses the validity of the hat brim line rule for skull fractures and looks at other possible criteria. All autopsy cases were retrospectively analyzed on a 5-year period. Cases selected consisted of downstairs falls (n = 13), falls from one's own height (n = 23), and homicidal blows (n = 44). Results show that fractures above the hat brim line are more in favor of blows, while fractures in the hat brim line zone are more difficult to distinguish. The majority of fractures were located on the left side for homicidal blows and on the right side for falls. A higher average number of lacerations was revealed for homicidal blows. In conclusion, this study establishes three criteria in favor of blows: (i) localization of a wound above the hat brim line; (ii) left side lateralization; and (iii) a high number of lacerations.
