Trang 2Child Abuse
• The physical, sexual, or mental injury,
exploitation or negligent treatment of a
child under the age of 18 years, by a person responsible for the child’s welfare
• Six patterns of abuse
Trang 3Child Abuse
• In the United States, 1 – 2% of children reported to be abused
• Incidence is 700 to 1,200 per million
• 2,000 – 4,000 deaths per year
• Age-range:
– One-third less than one year.
– One-third 1 – 6 years
– One-third 6 – 18 years
Trang 4Child Abuse
• The Abuser
– Parents (father more often than mother) – Other caregivers (boyfriends, babysitters) – Physically or emotionally exhausted
– Alcohol or other drugs often involved
Trang 5Injuries in Child Abuse
• Blunt injuries to any body surface most
common injury
• Head injury most common fatal injury
• Blunt trauma to abdomen also common
• Skeletal injuries, burns, drownings are also seen
Trang 6General characteristics of child
abuse
• Injury unexplained by the history given
• Delay in seeking care
• Changing, evolving, or inconsistent history
• Inappropriate affect of caregivers
• “Trigger event” precipitating loss of control
Trang 7Non-accidental Head Injuries
• Formerly known as “Shaken Baby
Syndrome”
• Common findings include:
– Subdural hemorrhage
– Retinal hemorrhage
– Diffuse axonal injury
– May or may not have external injuries
Trang 8Non-accidental Head Injuries
• The term Shaken Baby Syndrome has lost
popularity in the United States and Great Britain Many investigators disagree on the biomechanics
of shaking infants, and many feel these injuries do not happen in this way For this reason, many
forensic pathologists have dropped the diagnosis
of Shaken Baby Syndrome for the more general
Trang 9Subdural Hemorrhages
• Results from tearing of bridging veins
extending from arachnoid to dura
• Hemorrhages are generally small and are markers of trauma
• Not a space occupying hemorrhage
• May be exceptionally small, or associated with focal sub-arachnoid hemorrhage
Trang 10Subdural hemorrhage
Trang 14Head injuries may or may not be present
Trang 17Differential Diagnosis of
Retinal Hemorrhage
• Birth Trauma-seen in 1/3 of vaginally
delivered babies, resolve quickly (weeks)
• Increased intracranial
pressure-arterio-venous mismatch
• Shaken baby syndrome
• Head trauma-Tearson syndrome, severe
head injuries, acceleration-deceleration injuries
Trang 18Differential Diagnosis of
Retinal Hemorrhage
• Sepsis
• Coagulopathy
• Subacute bacterial endocarditis
• Sickle cell disease
• Acute leukemias
Trang 21Subdural hemorrhage
Trang 22Subdural hemorrhage: Cross sections of optic nerves
Trang 25Subdural hemorrhage, optic nerve
Trang 26Diffuse Axonal Injury
• Result from shear-force type injuries to the brain.
• May be associated with cerebral white matter
tears, often seen at gray-white junction
• Disruption of neuronal axons with formation of axonal “retraction balls”, best seen with silver impregnation or immunohistochemical stains.
