Non-accidental injury Flashcards
What are RF’s for non-accidental injury (NAI)?
Hx of Intimate Partner Violence and Abuse
Substance Abuse or Mental Health Condition in one or both caregivers
Excessive crying
Unintended pregnancy
Developmental problems
Child: disability, “wrong gender”, result of non-consensual sex
Parent: Mental health problems, substance misuse, indifference
Family: domestic violence, social isolation, young age, multiple births, step rather than biological parent
Environment: poverty, poor housing
Hx of Intimate Partner Violence (IPC) and Abuse as a RF?
- Physical, Sexual, Psychological, Emotional, Verbal, Financial, Neglect, Fabricated induced illness
- Study showed that if IPV occurred w/in child’s first 6 months, physical abuse is ~ 3 times more likely
- If IPV is suspected, but not documents, discuss immediately with senior
What questions can you ask to elicit hx of IPV?
Indirect questions:
- Is everything ok at home?
- Is your partner supportive?
- If the woman is pregnant:
– Are you being looked after properly?
– Is your partner taking care of you?
Direct questions:
- Do you ever feel frightened of your partner?
- Have you ever been in a relationship where you have been hit or hurt in some way?
- Are you currently in a relationship where this is happening to you?
How can substance abuse or Mental health condition in one or both caregivers increase NAI risk?
through increased burden on the caregiver/caregivers
How is excessive crying a RF for NAI?
Excessive crying, especially aged 0-4 months old, has been identified as a trigger for shaking of infants.
This is a common cause of NAI
How is unintended pregnancy a RF for NAI?
Study found that unintended pregnancy carried an odds ratio of 2.92 for maltreatment/NAI
How are developmental problems a RF for NAI?
Children with developmental concerns were twice as likely to suffer maltreatment during a study within the UK.
This may be due to the increased burden on caregivers, caused by these children’s complex health needs.
What should raise suspicion about NAI?
Presentation
Hx
Timeframe
Pt presenting late with obvious injury
Implausible hx for the presenting complaint
What different sx may present?
Bruises
Bites
Lacerations/Abrasions
Thermal Injuries
Fractures
Intracranial injuries
Eye trauma
Other
What features should you look at in bruises?
Shape
- Worrying: shaped like hands, linear brushes, ligatures, identifiable implement
Pattern
- Bruises on non-bony parts of the body or face/ears
- Multiple (of uniform shape) or clustered bruises
- Bruises a/w petechiae
Age
- Be suspicious of bruises in a child who cannot mobilise
- Remember “if they can’t cruise they don’t bruise”
- Bruising in babies
What features of bites should you look at?
- Any bit which appears to be human should be treated as suspicious - can be caused by other children but must get an adequate explanation
- Animal bights not classical NAI but may be sign of poorly supervised child
What features should you look at in lacerations?
High suspicion if laceration seen:
- In non-mobile children
- Symmetrically
- Around the face
- Around the ankles or wrists, in the position a ligature could be applied
Always get an adequate explanation!
When should you suspect NAI in terms of thermal injuries?
Affected area:
Suspect NAI where thermal injuries are in locations you would not expect to come into contact with a hot object:
- Soles of the feet
- Buttocks/back
- Backs of hands
Shape of the burn/scald
- Suspect NAI where an injury is in the shape of a conceivable implement such as a cigarette or iron
Scalds with sharply delineated borders should arouse suspicion (consider immersion injury)
What features should you assess in a fracture?
- Fractures, single or multiple, in children WIHTOUT a medical condition predisposing them to fragile bones, should be investigated for NAI.
- Fractures of different ages, especially where there is no documentation of caregivers seeking medical attention, are highly suspicious of NAI.
- Metaphyseal corner fractures – reported as almost pathognomonic of NAI.
- Evidence of occult rib fractures is also a common finding in infants/children who have been grabbed by the chest and squeezed/shaken.
- Spiral fractures are a result of twisting forces so cannot be caused by simple falling, and are highly suspicious of NAI
When should you suspect NAI with intracranial injuries?
Suspect NAI where intracranial injury presents:
- Without an adequate explanation
- In a child < 3 y/o
- In the presence of:
– Retinal haemorrhage
– Rib or long bone fractures
– Other associated injuries
- With multiple subdural haemorrhages
What eye trauma is suspicious of NAI?
Retinal haemorrhages with no medical explanation
What other injuries raise suspicion for NAI?
Spinal injuries or visceral injuries without a history of major trauma should be thoroughly investigated for suspected NAI.
What are DD’s of NAI?
Coagulopathy
- May lead to excessive bruising and haemarthrosis.
- FHx most likely present, but coagulation screening should be undertaken to rule this out.
Osteogenesis Imperfecta
- FHx may be present, and the condition would typically be detected early in life.
- X-ray findings typically show decreased bone density, so a skeletal survey would rule this out.
How should abuse be assessed for?
General hx
Family setup
Siblings
Parents - work, health, drugs
Social care involvement
Police involvement
Examination - body, map, observation
What investigations can be done in cases of child abuse?
Bloods - ?clotting in bruising
Skeletal survey - Fractures
CT brain - Intracranial haemorrhages
Ophthalmology - Retinal haemorrhages
Forensic
- Child death
- Sexual abuse
What imaging is required in suspected NAI?
Skeletal survey
Follow up imaging
Neurological imaging
Alternative Skeletal imaging
What does a skeletal survey entail?
Head/chest (including AP and lateral skull)
Spine/pelvis
Upper limbs
Lower limbs
What does follow up imaging entail?
Skeletal survey repeated at 11-14 days - to ensure that injuries too new to appear on the initial skeletal survey are detected.
11-14 days is used as this is the maximal time take for the periosteal reaction to occur, allowing fractures to be visualised on X-ray.
What does neurological imaging entail?
Depends on timing of presentation
Acute presentation:
- CT head as soon as pt is stabilised on the day of the presentation
Non-acute presentation
- MRI head performed as soon as possible, within a week of presentation
