Insights
Young children with severe abdominal injuries, particularly hollow viscous or pancreatic injuries, especially when combined with brain injury or undernourishment, may indicate child abuse. Increased awareness of these injury patterns can improve medical evaluations.
Area of Science:
- Pediatric Trauma
- Child Abuse Forensics
- Injury Epidemiology
Background:
- Blunt abdominal trauma in young children can be challenging to diagnose.
- Distinguishing accidental injuries from non-accidental trauma is crucial for patient safety and intervention.
Purpose of the Study:
- To identify specific patient and injury characteristics associated with suspected child abuse in pediatric blunt abdominal trauma.
- To improve the diagnostic accuracy for child abuse in pediatric trauma cases.
Main Methods:
- Analysis of data from the National Pediatric Trauma Registry (N=106,135) for blunt abdominal injuries in children aged 0-4 years, excluding motor vehicle incidents.
- Independent variables included age, mortality, nutritional status, and injury type; the dependent variable was suspected child abuse.
Main Results:
- Suspected child abuse was the most common mechanism of injury (40.5%) in the analyzed cohort.
- Severe hollow viscous (OR, 9.5) and pancreatic (OR, 9.5) injuries, along with traumatic brain injury (OR, 3.6), were significantly associated with suspected abuse.
- Eighty-four percent of deaths were linked to suspected child abuse.
Conclusions:
- Young children presenting with severe pancreatic, hollow viscous, or abdominal injuries, particularly when co-occurring with brain injury or undernourishment, warrant thorough evaluation for abuse.
- Enhanced awareness of these injury patterns can lead to more consistent and comprehensive medical assessments for suspected child abuse.
Objective:
To identify patient and injury characteristics associated with suspected child abuse in the setting of blunt abdominal trauma.
Patients:
We extracted from the National Pediatric Trauma Registry phases 2 and 3 (October 1995 to April 2001; N = 106,135) all cases of blunt abdominal injury, excluding motor vehicle injuries, in patients aged 0 to 4 years.
Main Outcome Measures:
Independent variables included age, mortality, nutritional status, and injury type. The dependent variable was suspected child abuse.
Results:
Six hundred sixty-four cases were analyzed. The median age of patients was 2.6 years; 11.4% were undernourished. The 3 most common mechanisms of injury were suspected child abuse (40.5%), fall (36.6%), and struck-not child abuse (9.7%). Hepatic injury (46.1%) was the most common intra-abdominal injury, followed by splenic (26%), hollow viscous (17.9%), and pancreatic (8.6%) injuries. Eighty-four percent of deaths were related to suspected child abuse. There was a greater proportion of children with suspected child abuse in every patient and injury characteristics studied than all other mechanisms combined. In a regression model including age, undernourishment, pancreatic injury, hollow viscous injury, traumatic brain injury, and mortality, all variables were significantly associated with suspected abuse. Hollow viscous injury had the highest odds ratio (OR, 9.5; confidence limits, 5.7, 15.8), whereas traumatic brain injury had the lowest (OR, 3.6; confidence limits, 2.4, 5.6).
Conclusions:
Young children with severe pancreatic or hollow viscous injuries or severe abdominal injuries in the context of either brain injury or undernourishment should be evaluated for the possibility that these injuries resulted from abuse. Increasing the awareness of the possibility of child abuse associated with a set of injury characteristics may allow for more consistent and complete medical evaluation.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
