Shaken Baby Syndrome

Head injury in the youngest age group is distinct from that occurring in older children or adults because of differences in mechanisms, injury thresholds, and the frequency with which the question of child abuse is encountered. "Shaken baby syndrome" has results in intracranial and introcular hemorrhages with no evidence of external trauma. The cause of these injuries is vigorous shaking of an infant being held by the chest, shoulders, or extremities. Severe head injuries commonly diagnosed as shaking injuries require impact to occur and that shaking alone in an otherwise normal baby is unlikely to cause the shaken baby syndrome. "Shaken impact syndrome" has the advantage of being more inclusive of verifiable impact mechanisms and of reflecting the extreme forces that appear to be necessary to produce these often devastating injuries. All clinicians must recognize the wide spectrum of injuries in child abuse to ultimate protect the victim or other children in an at-risk situation. And physicians play an important role in diagnosis, management and prevention of child abuse and shaken baby syndrome.

A Case of Shaken Impact Syndrome with Encephalomalacia / 대한소아신경학회지

Head trauma is the most frequent cause of morbidity and death in abused children. The shaken impact syndrome results from both types of injury-impact and severe acceleration-deceleration effects associated with impact causing shearing forces on the bridging veins and parechyma. To make the diagnosis of shaken impact syndrome, the physician should be suspicious of every child under 1 year of age with non-accidental brain injury and altered consciousness. Certain clinical features such as retinal hemorrhage , complex, depressed, or diastatic fractures, and associated findings such as metaphyseal fracture and failure to thrive make the diagnosis of abuse more likely. Yet in the absence of these findings, the diagnosis of abuse rests upon discrepancies between the history given and the injury incurred. We experienced a case of shaken impact syndrome in a 13 month-old female who had subdural hemorrhage, fractures of skull and rib, and encephalomalacia, so we report and review the related literatures.
