Blast injury in children: an analysis from Afghanistan and Iraq, 2002-2010.

BACKGROUND: Throughout history, children have been victims of armed conflict, including the blast injury complex, however, the pattern of injury, physiologic impact, and treatment needs of children with this injury are not well documented. METHODS: The Joint Theatre Trauma Registry provides data on all civilians admitted to US military treatment facilities from 2002 to 2010 with injuries from an explosive device. The data were stratified by age and analyzed for differences in anatomic injury patterns, Injury Severity Score (ISS), Revised Trauma Score (RTS), mortality, intensive care unit days, and length of hospitalization. Multivariate logistic regression was done to determine independent predictors of mortality. All operative procedures with a specified site were tabulated and categorized by body region and age. RESULTS: A total of 4,983 civilian patients were admitted, 25% of whom were younger than 15 years. Pediatric patients aged 8 to 14 years had a higher ISS and hospital stay than other age groups, and children younger than 15 years had a longer intensive care unit stay. Injuries in children were more likely to occur in the head and neck and less likely in the bony pelvis and extremities. Children had a lower RTS than the other age groups. Mortality correlated highly with burns, head injury, transfusion, and RTS. Adolescent patients had a lower mortality rate than the other age groups. Improvised explosive devices were the most common cause of injury in all age groups. CONCLUSION: Children experiencing blast injury complex have an anatomic pattern that is unique and an RTS that reflects more severe physiologic derangement. Injuries requiring transfusion or involving the head and neck and burns were predictive of mortality, and this persisted across all age groups. The mortality rate of children with blast injury is significant (7%), and treatment is resource intensive, requiring many surgical subspecialties. LEVEL OF EVIDENCE: Epidemiologic study, level III.

Preventing unintentional pediatric injuries at evacuation centers.

Injury to children 1 to 14 years of age is the leading cause of death worldwide. The US has made concerted efforts to reduce the injury death rate to children by 45%. Such success depends on a multifaceted strategy that requires local, community coalitions and effective customized solutions. During a natural disaster, the risk of injury for children increases with the movement to a "safe environment." Implementation of low cost, effective injury prevention has a salutary impact upon the lives of children and can reduce the risk of preventable unintentional injury during a natural disaster.

Intercostal hernia and spontaneous pneumothorax in a liver transplant recipient: a case report.

Intercostal hernia can occur after blunt trauma and can also complicate thoracotomy. This report describes a 13-year-old liver transplant recipient with chronic asymptomatic intercostal hernia at site of thoracotomy. This hernia became manifest upon development of spontaneous pneumothorax. She presented with pleuritic pain and radiographic evidence of spontaneous pneumothorax. Her history included liver transplantation at age 19 months for tyrosinemia, posttransplant lymphoproliferative disorder at age 7 years with thoracotomy for lung biopsy, and prolonged corticosteroid administration. Examination and computed tomography revealed an intercostal hernia. She underwent repair of hernia, stapled resection of apical blebs, and pleurodesis. Reconstruction of chest wall involved rib fracture and intercostal approximation with nonabsorbable sutures covered by serratus muscle advancement. She is symptom free with intact repair 2 years and 9 months after surgery and is able to participate in vigorous physical activity. This is the first report of an intercostal hernia detected upon development of spontaneous pneumothorax. The hernia occurred at the site of a prior thoracotomy, possibly because of impaired healing from corticosteroid administration. This case suggests that nonabsorbable sutures should be used for intercostal approximation after thoracotomy in patients with impaired wound healing.

Analysis of head injury admission trends in an urban American pediatric trauma center.

BACKGROUND: Head injury is the leading cause of death in children. Child safety legislation and risk-specific intervention programs have flourished to mitigate the incidence of injury to children. This analysis documents the trend in head injury to children in a specific institution. METHODS: Analysis of 5,003 head injury admissions to a pediatric trauma center over thirteen years was performed. Admission rates were calculated using the appropriate population denominator from census data. Poisson regression analysis was applied to estimate the relative risk of head injury admission by year in different age, sex, mechanism of injury and severity group. RESULTS: There has been a 70% decline in the head injury admission rate since 1989, consistent with regional and national data. The decline was present in all mechanisms of injury and age groups except for less than 1 year of age. The decline in total trauma admissions over the same time period was 50% and the decline in total hospital admission was 10%. CONCLUSION: Pediatric head injury has significantly declined in the last 13 years at a Level I pediatric trauma center.

Hospital- and patient-level characteristics and the risk of appendiceal rupture and negative appendectomy in children.

CONTEXT: The rates of appendiceal rupture and negative appendectomy in children remain high despite efforts to reduce them. Both outcomes are used as measures of hospital quality. Little is known about the factors that influence these rates. OBJECTIVE: To investigate the association between hospital- and patient-level characteristics and the rates of appendiceal rupture and negative appendectomy in children. DESIGN, SETTING, AND PATIENTS: Retrospective review using the Pediatric Health Information System database containing information on 24,411 appendectomies performed on children aged 5 to 17 years at 36 pediatric hospitals in the United States between 1997 and 2002. MAIN OUTCOME MEASURES: Rates of negative appendectomy and appendiceal rupture; the odds ratio (OR) of negative appendectomy and appendiceal rupture by hospital, patient age, race, and health insurance status, and hospital fiscal year and appendectomy volume. Negative appendectomy rate was defined as the number of patients with appendectomy but without appendicitis divided by the total number of appendectomies. RESULTS: The median negative appendectomy rate was 3.06% (range, 1%-12%) and the median appendiceal rupture rate was 35.08% (range, 22%-62%). The adjusted OR for appendiceal rupture was higher in Asian children (1.66; 95% confidence interval [CI], 1.24-2.23) and black children (1.13; 95% CI, 1.01-1.30) compared with white children. Children without health insurance and children with public insurance had increased odds of appendiceal rupture compared with children who had private health insurance (adjusted OR, 1.36; 95% CI, 1.22-1.53 for self-insured; adjusted OR, 1.48; 95% CI, 1.34-1.64 for public insurance). No correlation existed between negative appendectomy rate and race, health insurance status, or hospital appendiceal rupture rate. The negative appendectomy rate improved as the hospital appendectomy volume increased. CONCLUSION: The rate of appendiceal rupture in school-aged children was associated with race and health insurance status and not with negative appendectomy rate and therefore is more likely to be associated with prehospitalization factors such as access to care, quality of care, and patient or physician education.

Gastroesophageal intussusception: a new cause of acute esophageal obstruction in children.

Gastrointestinal intussusception with obstruction is common in the small bowel and colon; however, such a process is not known to cause esophageal obstruction. Recent experience with gastroesophageal intussusception permits discussion of diagnosis and consideration of treatment options. A 3-year-old child presented with acute esophageal obstruction. Physical examination was significant for epigastric tenderness and excessive salivation. Chest x-ray showed a posterior mediastinal fullness. Esophagram documented a smooth crescent-filling defect, which caused obstruction of the esophagus at the level of the carina with proximal esophageal dilatation. Chest computed tomography of the thorax showed a soft tissue mass of the distal esophagus. Esophagoscopy confirmed occlusion of the midesophagus with the mucosa intact. A right thoracotomy permitted visualization of dilated proximal esophagus and a palpation of an intraluminal mass in the distal esophagus. Mobilization of the distal esophagus and gentle manual pressure cleared the obstruction to a point below the diaphragm. After a normal intraoperative esophagram, final treatment consisted of a longitudinal esophagomyotomy. The child recovered without complication and continues without recurrence for 18 months. This is the first report of gastroesophageal intussusception in children. Management by thoracotomy, manual reduction, and esophageal myotomy reestablished intestinal continuity and appears to eliminate recurrence; fundoplication or gastropexy may be alternative options. Preoperative recognition of gastroesophageal intussusception may allow nonoperative reduction or treatment by minimally invasive surgery.

Not all child safety seats are created equal: the potential dangers of shield booster seats.

OBJECTIVE: Children are safest when traveling in a child safety seat appropriate for their age and size. Previous research indicates that children are often transitioned to shield booster seats (SBSs) before reaching the 40-lb weight limit for their forward-facing child safety seat (FFCSS). These children could have otherwise been restrained in a FFCSS as is currently recommended by the American Academy of Pediatrics and the National Highway Traffic Safety Administration. The objective of this study was to compare the injury patterns among children who were restrained in SBSs and FFCSSs. Children in FFCSSs were chosen as a comparison group because SBS are predominantly used to restrain children who are <40 lb and could have been restrained in an FFCSS, and SBSs are no longer certified for use in children who are >40 lb. METHODS: This is a cohort study involving restrained crash victims who were admitted to a level 1 pediatric trauma center between 1991 and 2003. Patients were older than 1 year, weighed between 20 and 40 lb, and were restrained in an SBS (N = 16) or an FFCSS (N = 30). Injury Severity Score, Abbreviated Injury Scale, Glasgow coma score, intensive care admission, length of stay, and acute care charges served as outcomes of interest. RESULTS: No significant differences regarding crash and occupant characteristics were found (mean Delta V, crash type, passenger compartment intrusion, driver restraint use). Odds of severe injury were greater for children in SBSs compared with children in FFCSSs as measured by Injury Severity Score >15 (odds ratio [OR]: 8.3; 95% confidence interval [CI]: 2.1-33.6), intensive care admission (OR: 5.5; 95% CI: 1.5-20.5), length of stay >2 days (OR: 6.3; 95% CI: 1.6-24.6), and Abbreviated Injury Scale > or = 3 (OR: 4.4; 95% CI: 1.2-16.1). Furthermore, SBS cases had greater odds of head (OR: 4.5; 95% CI: 1.2-17.3), chest (OR: 29.0; 95% CI: 3.1-267.3), and abdominal/pelvic injury (25% vs 0%). CONCLUSION: This study provides information about the increased risk of injury associated with shield boosters when compared with FFCSSs. The challenge for pediatricians is not only to promote the use of child restraints but also to ensure that parents use the most appropriate restraint for their child's age and weight.

Patterns of injury to restrained children in side impact motor vehicle crashes: the side impact syndrome.

BACKGROUND: Injury patterns among children in frontal collisions have been well documented, but little information exists regarding injuries to children in side impact collisions. METHODS: Restrained children 14-years-old or younger admitted to the hospital for crash injuries were analyzed. Data concerning injuries, medical treatment, and outcome were correlated with crash data. Case reviews achieved consensus regarding injury contact points. Side impacts were compared with frontal impacts. These results were then compared with data from the National Automotive Sampling System. RESULTS: There were no differences between the groups with respect to age, sex, restraint type, or seat position. Compared with frontal crashes, children in side impacts were more likely to have an Injury Severity Score > 15 (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.7-5.8) and were more likely to have Abbreviated Injury Scale score 2+ injuries to the head (OR, 2.5; 95% CI, 1.4-4.4), chest (OR, 4.0; 95% CI, 2.0-8.0), and cervical spine (OR, 3.7; 95% CI, 1.2-11.3). When compared with National Automotive Sampling System data, similar trends were seen regarding Abbreviated Injury Scale score 2+ injuries to the head, chest, and extremities. CONCLUSION: In this study population, side impacts resulted in more injuries to the head, cervical spine, and chest. Knowledge of this pattern-the side impact syndrome-can help guide diagnosis, treatment, and prevention strategy.

Classical positioning decreases subclavian vein cross-sectional area in children.

BACKGROUND: Recommendations for subclavian vein catheter placement in children are extrapolated from adult experience. The purpose of this study was to determine the ideal body position to optimize the size of the subclavian vein in children for percutaneous catheter placement. METHODS: Children underwent ultrasound imaging of the subclavian vein in four supine body positions: head in a neutral position with the chin midline (NL) and no shoulder roll (SR); head turned 90 degrees away (TA) and no SR; head NL with an SR; and head TA with an SR. The cross-sectional area (CSA) of the subclavian vein was calculated and statistical significance was determined using the Student's t test and the Wilcoxon signed rank test. RESULTS: Nine children participated in the study, with a mean age of 5.3 years. The CSA of the subclavian vein was 0.39 +/- 0.24 cm2 with the head NL and no SR, compared with 0.31 +/- 0.20 cm2 with the head TA or 0.32 +/- 0.23 cm2 with the head TA and SR. This represented a significant reduction in the CSA of the subclavian vein by 22% and 18%, respectively (p < 0.05). CONCLUSION: In children, the recommended maneuvers of turning the head or turning the head and placing a posterior shoulder roll significantly reduce the cross-sectional area of the subclavian vein. Maintaining the head in a normal position with the chin midline without a shoulder roll optimizes subclavian vein size. Positioning children in this manner may serve to reduce the morbidity associated with percutaneous subclavian vein cannulation.

Routine MRI evaluation of low imperforate anus reveals unexpected high incidence of tethered spinal cord.

BACKGROUND/PURPOSE: Previous clinical practice has included evaluation for the presence of tethered cord in those children who have imperforate anus with a high lesion. To define the incidence in children with low lesions, the authors reviewed their experience with a protocol employing routine magnetic resonance imaging (MRI), regardless of the level of the lesion, to determine the presence of a tethered cord in all children with imperforate anus. METHODS: A retrospective review of children with imperforate anus was conducted over the last 13 years at our institution. Lesions were categorized as high versus low based on the supralevator or infralevator position of the fistula. RESULTS: Sixty-three patients completed evaluation for a tethered cord. Twenty-two (34.9%) of these 63 patients had a tethered cord: 11 of 41 (26.8%) patients with high lesions and 11 of 22 (50.0%) of those with low lesions. Of those children with a low lesion, 83% of the boys had a tethered cord, whereas 38% of the girls had a tethered cord. Forty-five percent of the patients with low lesions and a tethered cord did not have any other lumbosacral anomalies. All 22 children with a tethered cord underwent surgical release. CONCLUSIONS: The incidence of tethered cord in children with low lesions of imperforate anus is not lower than those with high lesions. The authors advocate early evaluation of all children with imperforate anus for a tethered cord.
