RESUMO
OBJECTIVE: The purpose of this study was to describe management and outcomes from a contemporary cohort of children with Wilms tumor complicated by inferior vena caval thrombus. BACKGROUND: The largest series of these patients was published almost 2 decades ago. Since then, neoadjuvant chemotherapy has been commonly used to manage these patients, and outcomes have not been reported. METHODS: Retrospective review of 19 North American centers between 2009 and 2019. Patient and disease characteristics, management, and outcomes were investigated and analyzed. RESULTS: Of 124 patients, 81% had favorable histology (FH), and 52% were stage IV. IVC thrombus level was infrahepatic in 53 (43%), intrahepatic in 32 (26%), suprahepatic in 14 (11%), and cardiac in 24 (19%). Neoadjuvant chemotherapy using a 3-drug regimen was administered in 82% and postresection radiation in 90%. Thrombus level regression was 45% overall, with suprahepatic level showing the best response (62%). Cardiopulmonary bypass (CPB) was potentially avoided in 67%. The perioperative complication rate was significantly lower after neoadjuvant chemotherapy [(25%) vs upfront surgery (55%); P =0.005]. CPB was not associated with higher complications [CPB (50%) vs no CPB (27%); P =0.08]. Two-year event-free survival was 93% and overall survival was 96%, higher in FH cases (FH 98% vs unfavorable histology/anaplastic 82%; P =0.73). Neither incomplete resection nor viable thrombus cells affected event-free survival or overall survival. CONCLUSIONS: Multimodal therapy resulted in excellent outcomes, even with advanced-stage disease and cardiac extension. Neoadjuvant chemotherapy decreased the need for CPB to facilitate resection. Complete thrombectomy may not always be necessary.

INTRODUCTION: The incidence of pediatric Wilms' tumor (WT) is high in Africa, though patients abandon treatment after initial diagnosis. We sought to identify factors associated with WT treatment abandonment in Uganda. METHODS: A cohort study of patients < 18 years with WT in a Ugandan national referral hospital examined clinical and treatment outcomes data, comparing children whose families adhered to and abandoned treatment. Abandonment was defined as the inability to complete neoadjuvant chemotherapy and surgery for patients with unilateral WT and definitive chemotherapy for patients with bilateral WT. Patient factors were assessed via bivariate logistic regression. RESULTS: 137 WT patients were included from 2012 to 2017. The mean age was 3.9 years, 71% (n = 98) were stage III or higher. After diagnosis, 86% (n = 118) started neoadjuvant chemotherapy, 59% (n = 82) completed neoadjuvant therapy, and 55% (n = 75) adhered to treatment through surgery. Treatment abandonment was associated with poor chemotherapy response (odds ratio [OR] 4.70, 95% confidence interval [CI] 1.30-17.0) and tumor size > 25 cm (OR 2.67, 95% CI 1.05-6.81). CONCLUSIONS: Children with WT in Uganda frequently abandon care during neoadjuvant therapy, particularly those with large tumors with poor response. Further investigation into the factors that influence treatment abandonment and a deeper understanding of tumor biology are needed to improve treatment adherence of children with WT in Uganda.

OBJECTIVE: To characterize the full spectrum of pediatric firearm injury in the United States by describing fatal and nonfatal injury data epidemiology, vulnerable populations, and temporal trends. BACKGROUND: Firearm injury is the leading cause of death in children and adolescents in the United States. Nonfatal injury is critical to fully define the problem, yet accurate data at the national level are lacking. METHODS: A cross-sectional study combining national firearm injury data from the Centers for Disease Control (fatal) and the National Trauma Data Bank (nonfatal) between 2008 and 2019 for ages 0 to 17 years. Data were analyzed using descriptive and χ 2 comparisons and linear regression. RESULTS: Approximately 5000 children and adolescents are injured or killed by firearms each year. Nonfatal injuries are twice as common as fatal injuries. Assault accounts for the majority of injuries and deaths (67%), unintentional 15%, and self-harm 14%. Black youth suffer disproportionally higher injuries overall (crude rate: 49.43/million vs White, non-Hispanic: 15.76/million), but self-harm is highest in White youth. Children <12 years are most affected by nonfatal unintentional injuries, 12 to 14 years by suicide, and 15 to 17 years by assault. Nonfatal unintentional and assault injuries, homicides, and suicides have all increased significantly ( P < 0.05). CONCLUSIONS: This study adds critical and contemporary data regarding the full spectrum and recent trends of pediatric firearm injury in the United States and identifies vulnerable populations to inform injury prevention intervention and policy. Reliable national surveillance for nonfatal pediatric firearm injury is vital to accurately define and tackle this growing public health crisis.

Wilms tumor (WT) is the most common renal malignancy in children. Children with favorable histology WT achieve survival rates of over 90%. Twelve percent of patients present with metastatic disease, most commonly to the lungs. The presence of a pleural effusion at the time of diagnosis of WT may be noted on staging imaging; however, minimal data exist regarding the significance and prognostic importance of this finding. The objectives of our study are to identify the incidence of pleural effusions in patients with WT, and to determine the potential impact on oncologic outcomes. A multi-institutional retrospective review was performed from January 2009 to December 2019, including children with WT and a pleural effusion on diagnostic imaging treated at Pediatric Surgical Oncology Research Collaborative (PSORC) participating institutions. Of 1259 children with a new WT diagnosis, 94 (7.5%) had a pleural effusion. Patients with a pleural effusion were older than those without (median 4.3 vs 3.5 years; P = .004), and advanced stages were more common (local stage III 85.9% vs 51.9%; P < .0001). Only 14 patients underwent a thoracentesis for fluid evaluation; 3 had cytopathologic evidence of malignant cells. Event-free and overall survival of all children with WT and pleural effusions was 86.2% and 91.5%, respectively. The rate and significance of malignant cells present in pleural fluid is unknown due to low incidence of cytopathologic analysis in our cohort; therefore, the presence of an effusion does not appear to necessitate a change in therapy. Excellent survival can be expected with current stage-specific treatment regimens.

Inflammatory myofibroblastic tumor (IMT) is a mesenchymal neoplasm of intermediate malignancy. We describe the largest cohort of IMT patients to date, aiming to further characterize this rare, poorly understood tumor. This is a multi-institutional review of IMT patients ≤39 years, from 2000 to 2018, at 18 hospitals in the Pediatric Surgical Oncology Research Collaborative. One hundred and eighty-two patients were identified with median age of 11 years. Thirty-three percent of tumors were thoracic in origin. Presenting signs/symptoms included pain (29%), respiratory symptoms (25%) and constitutional symptoms (20%). Median tumor size was 3.9 cm. Anaplastic lymphoma kinase (ALK) overexpression was identified in 53% of patients. Seven percent of patients had distant disease at diagnosis. Ninety-one percent of patients underwent resection: 14% received neoadjuvant treatment and 22% adjuvant treatment. Twelve percent of patients received an ALK inhibitor. Sixty-six percent of surgical patients had complete resection, with 20% positive microscopic margins and 14% gross residual disease. Approximately 40% had en bloc resection of involved organs. Median follow-up time was 36 months. Overall 5-year survival was 95% and 5-year event-free survival was 80%. Predictors of recurrence included respiratory symptoms, tumor size and distant disease. Gross or microscopic margins were not associated with recurrence, suggesting that aggressive attempts at resection may not be warranted.

OBJECTIVE: To determine the impact of tumor characteristics and treatment approach on (1) local recurrence, (2) scoliosis development, and (3) patient-reported quality of life in children with sarcoma of the chest wall. SUMMARY OF BACKGROUND DATA: Children with chest wall sarcoma require multimodal therapy including chemotherapy, surgery, and/or radiation. Despite aggressive therapy which places them at risk for functional impairment and scoliosis, these patients are also at significant risk for local recurrence. METHODS: A multi-institutional review of 175 children (median age 13 years) with chest wall sarcoma treated at seventeen Pediatric Surgical Oncology Research Collaborative institutions between 2008 and 2017 was performed. Patient-reported quality of life was assessed prospectively using PROMIS surveys. RESULTS: The most common diagnoses were Ewing sarcoma (67%) and osteosarcoma (9%). Surgical resection was performed in 85% and radiation in 55%. A median of 2 ribs were resected (interquartile range = 1-3), and number of ribs resected did not correlate with margin status ( P = 0.36). Local recurrence occurred in 23% and margin status was the only predictive factor(HR 2.24, P = 0.039). With a median follow-up of 5 years, 13% developed scoliosis (median Cobb angle 26) and 5% required corrective spine surgery. Scoliosis was associated with posteriorrib resection (HR 8.43; P= 0.003) and increased number of ribs resected (HR 1.78; P = 0.02). Overall, patient-reported quality of life is not impaired after chest wall tumor resection. CONCLUSIONS: Local recurrence occurs in one-quarter of children with chest wall sarcoma and is independent of tumor type. Scoliosis occurs in 13% of patients, but patient-reported quality of life is excellent.

INTRODUCTION: Studies have shown the benefit of intensive care unit (ICU) bundled protocols; however, they are primarily derived from medical patients. We hypothesized that patients and their medication profiles are different between critically ill medical, surgical, and trauma patients. METHODS: The Pediatric Health Information System 2017 dataset was used to perform a retrospective cohort study of critically ill children. The pediatric medical, surgical, and trauma cohorts were separated based on ICD-10 codes. Data collected included demographics, secondary diagnoses, outcomes, and medication data. Medications were grouped as opiates, GABA-agonists, alpha-2 agonists, anti-psychotics, paralytics, and "other" sedatives. A non-parametric Kolmogorov-Smirnov test (KS test) and odds ratios (reference group: medical cohort) were calculated to compare medication administration between the study cohorts for the first 30 ICU days. RESULTS: A total of 4488 critically ill children (medical 2078, surgical 1650, and trauma 760) were identified. The trauma cohort had increased incidence of delirium (medical 10.8%, surgical 11.5%, trauma 13.8%; p < 0.01) and mortality (medical 5.4%, surgical 2.4%, trauma 11.7%; p < 0.01). For all study cohorts, > 50% received GABA-agonists on ICU days 0-30. With the KS test, there was a significant difference in administration of opiates, GABA-agonists, alpha-2 agonists, anti-psychotics, and "other" sedatives over the first 30 days in the ICU. Relative to medical patients, trauma patients had significantly higher odds of receiving anti-psychotics on ICU days 10-20 and 22-24. CONCLUSION: Critically ill pediatric trauma, medical, and surgical patients are distinctly different patient populations with differing pharmacologic profiles for analgesia, sedation, and delirium. LEVEL OF EVIDENCE: Level III (Retrospective Comparative Study).

BACKGROUND: Pediatric trauma patients sustaining blunt abdominal trauma (BAT) with intra-abdominal injury (IAI) are frequently admitted to the intensive care unit (ICU). This study was performed to identify predictors for ICU admission following BAT. METHODS: Prospective study of children (< 16 years) who presented to 14 Level-One Pediatric Trauma Centers following BAT over a 1-year period. Patients were categorized as ICU or non-ICU patients. Data collected included vitals, physical exam findings, laboratory results, imaging, and traumatic injuries. A multivariable hierarchical logistic regression model was used to identify predictors of ICU admission. Predictive ability of the model was assessed via tenfold cross-validated area under the receiver operating characteristic curves (cvAUC). RESULTS: Included were 2,182 children with 21% (n = 463) admitted to the ICU. On univariate analysis, ICU patients were associated with abnormal age-adjusted shock index, increased injury severity scores (ISS), lower Glasgow coma scores (GCS), traumatic brain injury (TBI), and severe solid organ injury (SOI). With multivariable logistic regression, factors associated with ICU admission were severe trauma (ISS > 15), anemia (hematocrit < 30), severe TBI (GCS < 8), cervical spine injury, skull fracture, and severe solid organ injury. The cvAUC for the multivariable model was 0.91 (95% CI 0.88-0.92). CONCLUSION: Severe solid organ injury and traumatic brain injury, in association with multisystem trauma, appear to drive ICU admission in pediatric patients with BAT. These results may inform the design of a trauma bay prediction rule to assist in optimizing ICU resource utilization after BAT. STUDY DESIGN: Prognosis study.

BACKGROUND: Children with cancer diagnosis are overall at a higher risk of thrombosis. For a newly diagnosed blood clot, patients are commonly started on anticoagulants to prevent further extension and embolization of the clot. In the rare instance that a pediatric patient has a tumor thrombus, role of anticoagulation is less clear. PROCEDURE/METHODS: Patients under 21 years of age with a finding of tumor thrombus on imaging from 2010 to 2020 at Texas Children's Hospital were identified and their medical records were reviewed. RESULTS: A total of 50 patients were identified. Most thrombi were incidental findings at diagnosis; however, two patients presented with pulmonary embolism (PE). Inferior vena cava extension was noted in 36% of the patients, and 24% patients had an intracardiac tumor thrombus. Anticoagulation was initiated in 10 patients (20%). There was no difference in the rate of bland thrombus formation and/or embolization in patients who did or did not receive anticoagulation. However, three of the six patients with asymptomatic tumor thrombus who were started on anticoagulation had bleeding complications compared to only two patients in the no anticoagulation cohort (p < .05). CONCLUSION: Children with intravascular extension of solid tumors were not commonly started on anticoagulation at the time of diagnosis, irrespective of the extent of tumor thrombus. Furthermore, we observed a significant trend toward higher incidence of bleeding complications after initiation of anticoagulation for asymptomatic tumor thrombus. There is inadequate evidence at this time to support routine initiation of anticoagulation in pediatric patients with intravascular extension of solid tumors.

OBJECTIVES: Firearms-related injuries and deaths are a leading cause of death in children and young adults ages 5 to 24 years. This study evaluated the counseling practices and barriers to providing safe firearms storage education by pediatricians and advance practice providers. METHODS: An online survey was sent to 296 pediatric outpatient providers in Houston, Texas. Pediatric providers were asked about demographics, knowledge, attitudes, and current practices regarding firearms safety counseling. Descriptive and comparative analyses were performed. RESULTS: Survey respondents (N = 76) were 86% women and 87% physicians. Most (86%) agree that they should discuss firearms safety with parents, whereas only 32% report routine counseling. The most frequent barrier to providing education was insufficient time (63%), followed by unfamiliarity with guns (26%). CONCLUSIONS: Pediatric providers are interested in firearms safety counseling, but few incorporate it into their practice. Addressing barriers of time and comfort level around firearms are potential first steps to curbing a leading cause of injury death among children. Further research is needed to develop counseling methods that are time efficient and culturally competent for the pediatric office.

OBJECTIVE: To establish a trauma preventable/potentially preventable death rate (PPPDR) within a heavily populated county in Texas. SUMMARY: The National Academies of Sciences estimated the trauma preventable death rate in the United States to be 20%, issued a call for zero preventable deaths, while acknowledging that an accurate preventable death rate was lacking. In this absence, effective strategies to improve quality of care across trauma systems will remain difficult. METHODS: A retrospective review of death-related records that occurred during 2014 in Harris County, TX, a diverse population of 4.4 million. Patient demographics, mechanism of injury, cause, timing, and location of deaths were assessed. Deaths were categorized using uniform criteria and recorded as preventable, potentially preventable or nonpreventable. RESULTS: Of 1848 deaths, 85% had an autopsy and 99.7% were assigned a level of preventability, resulting in a trauma PPPDR of 36.2%. Sex, age, and race/ethnicity varied across preventability categories (P < 0.01). Of 847 prehospital deaths, 758 (89.5%) were nonpreventable. Among 89 prehospital preventable/potentially preventable (P/PP) deaths, hemorrhage accounted for 55.1%. Of the 657 initial acute care setting deaths, 292 (44.4%) were P/PP; of these, hemorrhage, sepsis, and traumatic brain injury accounted for 73.3%. Of 339 deaths occurring after initial hospitalization, 287 (84.7%) were P/PP, of these 117 resulted from sepsis and 31 from pulmonary thromboembolism, accounted for 51.6%. CONCLUSIONS: The trauma PPPDR was almost double that estimated by the National Academies of Sciences. Data regarding P/PP deaths offers opportunity to target research, prevention, intervention, and treatment corresponding to all phases of the trauma system.

BACKGROUND: Wilms tumor accounts for more than 90% of all malignant kidney neoplasms in children. Survival after diagnosis and treatment is excellent in most high-income countries. Low- and middle-income countries (LMICs) continue to struggle with Wilms tumor detection and treatment. The purpose of this study was to compare the global incidence and outcomes of Wilms tumor. MATERIAL AND METHODS: Wilms tumor incidence data from the World Health Organization (WHO), International Incidence of Childhood Cancer, Volume III, was analyzed according to world region and country socioeconomic status using descriptive statistics and independent-sample Kruskal-Wallis Test. A literature review was also performed to assess outcomes and identify common themes. RESULTS: Wilms tumor was most common in children aged 0-4 y (median incidence 15.1 [IQR 11.8-18.7] ASR/million). High-income countries reported significantly higher median incidence than middle-income countries (8.6 [7.4-9.3] versus 6.1 [4.9-8.7] ASR/million; P < 0.01), although low-income countries reported the highest median incidence overall (9.8 [6.2-16.4] ASR/million). Low-income countries had the fewest countries with registries (n = 6). Overall survival ranged from 70% to 97% in high-income countries, 61%-94% in upper-middle-income countries, 0%-85% in lower-middle-income countries, and 25%-53% in low-income countries. Delay in diagnosis, lack of available treatment, and inadequate follow up contributed to the large variations in outcomes. CONCLUSIONS: Reported Wilms tumor incidence is highest in low-income countries, and these are also the countries that have the lowest survival. Lack of significance may reflect incomplete and absent data reporting from lower income countries. Accurate and comprehensive registries are the first steps to appropriate resource allocation in order to improve outcomes for this highly curable childhood malignancy.

Firearm-related deaths are on the rise in the United States, especially among our youth. Tragically, proper firearm storage and safety could have prevented a great number of these deaths. Professional and public health organizations have thus encouraged physicians to provide direct patient counseling on firearm safety. Yet, even with these recommendations, the majority of physicians are still not talking to their patients about this issue. There may be many reasons for this, including concerns about liability, feeling unprepared, patient discomfort, and lack of time during office visits. Despite these concerns, we argue that physicians have an ethical obligation to discuss firearm safety with their patients. Making these discussions a part of routine clinical care would go a long way in the bipartisan effort to protect public safety and improve public health.

BACKGROUND: Image-guided percutaneous core needle biopsy (PCNB) is increasingly utilized to diagnose solid tumors. The objective of this study is to determine whether PCNB is adequate for modern biologic characterization of neuroblastoma. PROCEDURE: A multi-institutional retrospective study was performed by the Pediatric Surgical Oncology Research Collaborative on children with neuroblastoma at 12 institutions over a 3-year period. Data collected included demographics, clinical details, biopsy technique, complications, and adequacy of biopsies for cytogenetic markers utilized by the Children's Oncology Group for risk stratification. RESULTS: A total of 243 children were identified with a diagnosis of neuroblastoma: 79 (32.5%) tumor excision at diagnosis, 94 (38.7%) open incisional biopsy (IB), and 70 (28.8%) PCNB. Compared to IB, there was no significant difference in ability to accurately obtain a primary diagnosis by PCNB (95.7% vs 98.9%, P = .314) or determine MYCN copy number (92.4% vs 97.8%, P = .111). The yield for loss of heterozygosity and tumor ploidy was lower with PCNB versus IB (56.1% vs 90.9%, P < .05; and 58.0% vs. 88.5%, P < .05). Complications did not differ between groups (2.9 % vs 3.3%, P = 1.000), though the PCNB group had fewer blood transfusions and lower opioid usage. Efficacy of PCNB was improved for loss of heterozygosity when a pediatric pathologist evaluated the fresh specimen for adequacy. CONCLUSIONS: PCNB is a less invasive alternative to open biopsy for primary diagnosis and MYCN oncogene status in patients with neuroblastoma. Our data suggest that PCNB could be optimized for complete genetic analysis by standardized protocols and real-time pathology assessment of specimen quality.

The Ewing sarcoma family of tumors (ESFT) are high-grade small round blue cell malignancies traditionally presenting in children and adolescents. The most common site of primary disease is bone, though extraskeletal primary sites are well-recognized. We present 6 cases of primary ESFT of the kidney and 1 case of the adrenal gland. Patients were 11 to 18 years of age at diagnosis. Metastases at diagnosis were present in most cases (n=6). All patients underwent surgery, and most received radiation (n=5). Five patients relapsed after initial remission. Comprehensive review of the primary renal ESFT literature was used to analyze various factors, including age, sex, disease metrics, metastases at diagnoses, and overall survival in a total of 362 cases. Notably, while the general ESFT population has reported rates of metastasis at diagnosis of 20% to 25%, this rate in the renal ESFT population was 53% with a rate of 59% in adolescent and young-adult patients (11 to 24 y). Nodal disease at diagnosis was present in 24% of renal ESFT cases compared with 3.2% in patients with primary skeletal ESFT. While this malignant process may share histologic and molecular features with its bone and soft tissue counterparts, primary renal ESFT presentations seem to be more aggressive and have worse outcomes.

OBJECTIVES: The aims of this study were to assess parent acceptance of firearms education delivered by clinical providers, determine whether parents engage in firearms safety dialog with their children, and evaluate reasons for ownership and storage behaviors. METHODS: The parents of children ages 0 to 18 years completed surveys while in a pediatric inpatient setting in Texas. Demographics, acceptability, current behaviors, and storage practices were queried. Responses between firearms owners and nonowners were analyzed using the Fisher exact and χ2 tests. RESULTS: Of the 115 parents who completed surveys, 41% reported owning firearms. Most parents were likely or highly likely to follow their pediatrician's gun safety advice (67%), were accepting of safety videos in waiting rooms (59%), and accepted firearms locks distributed by clinical providers (69%). Nonowners were less likely than owners to have spoken to their children about gun safety (P = 0.004). Parents owned firearms for self-protection and recreation (50%), self-protection only (38%), or recreation only (12%). Owners stored them unloaded (75%), used safety devices (95%), and stored them in the closet of the master bedroom (54%). CONCLUSIONS: Talking about firearms safety in a healthcare setting was not a contentious issue in the majority of our sample. Parents were accepting of provider-led firearms guidance regardless of ownership status. This provides an opportunity for providers to focus on effective messaging and time-efficient delivery of firearms safety education.

PURPOSE: Although trauma is the leading cause of death for the pediatric population, few studies have addressed the preventable/potentially preventable death rate (PPPDR) attributable to trauma. METHODS: This is a retrospective study of trauma-related death records occurring in Harris County, Texas in 2014. Descriptive and Chi-squared tests were conducted for two groups, pediatric and adult trauma deaths in relation to demographic characteristics, mechanism of injury, death location and survival time. RESULTS: There were 105 pediatric (age < 18 years) and 1738 adult patients. The PPPDR for the pediatric group was 21.0%, whereas the PPPDR for the adult group was 37.2% (p = 0.001). Analysis showed fewer preventable/potentially preventable (P/PP) deaths resulting from any blunt trauma mechanism in the pediatric population than in the adult population (19.6% vs. 48.4%, p < 0.001). Amongst the pediatric population, P/PP traumatic brain injury (TBI) were more common in the youngest age range (age 0-5) vs. the older (6-12 years) pediatric and adolescent (13-17 years) patients. CONCLUSION: Our results identify areas of opportunities for improving pediatric trauma care. Although the overall P/PP death rate is lower in the pediatric population than the adult, opportunities for improving initial acute care, particularly TBI, exist.

BACKGROUND: The purpose of this study was to identify an optimal definition of massive transfusion in civilian pediatric trauma with severe traumatic brain injury (TBI) METHODS: Severely injured children (age ≤18 y) with severe TBI in the Trauma Quality Improvement Program research data sets 2015-2016 that received blood products were identified. Data were analyzed using descriptive statistics, Wilcoxon rank-sum, chi-square, and logistic regression. Continuous variables are presented as median (interquartile range). Massive transfusion thresholds were determined based on receiver operating curves and optimization of sensitivity and specificity RESULTS: Of the 460 included children, the mortality rate was 43%. There were no differences in demographics, heart rate at presentation, or injury severity score between children that lived or died. However, those who died had lower Glasgow coma scores (3 [3, 8] versus 3 [3, 3]; P < 0.01), were more likely to have had a penetrating injury (20% versus 11%; P < 0.01) and were more likely to be hypotensive for age (62% versus 34%; P < 0.01). Total blood products infused were greater in those who died (34 mL/kg/4-h [17, 65] versus 22 [12, 44]; P < 0.01). Sensitivity and specificity for delayed mortality was optimized at 40 mL/kg/4 h, and for the need for a hemorrhage control procedure at 50 mL/kg/4 h. These thresholds predicted delayed mortality (OR 2.12; 95% CI 1.28-3.50; P < 0.01) and the need for hemorrhage control procedures (5.47; 95% CI 2.82-10.61; P < 0.01) CONCLUSIONS: For children with TBI, a massive transfusion threshold of 40 mL/kg/4-h of total administered blood products may be used to identify at-risk patients, improve resource utilization, and guide future research methodology.

BACKGROUND: Massive transfusion protocols with balanced blood product ratios have been associated with improved outcomes in adult trauma. The impact on pediatric trauma is unclear. MATERIAL AND METHODS: A retrospective review of the Pediatric Trauma Quality Improvement Program data set was performed using data from January 2015 to December 2016. Trauma patient's ≤ 18 y of age, who received red blood cells (RBCs) and were massively transfused were included. Children with burns, dead on arrival, and nonsurvivable injuries were excluded. Outcome data and mortality were assessed based on low (<1:2), medium (≥1:2, <1:1), and high (≥1:1) plasma and platelet to RBC ratios. RESULTS: There were 465 children included in the study (median age, 8 [2-16] y; median injury severity score, 34 [29-34]; mortality rate, 38%). Those transfused a medium plasma:RBC ratio received the greatest blood product volume in 24 h (90 [56-164] mL/kg; P < 0.01). Those in the low plasma:RBC group underwent fewer hemorrhage control procedures [56 (34%); P < 0.01], but ratio was not significant when controlling for age and other variables. Survival was improved for those who received a high plasma:RBC ratio (P = 0.02). Platelet transfusions were skewed toward lower ratios (95%) with no difference in clinical outcomes between the groups. CONCLUSIONS: A high ratio of plasma:RBC may result in decreased mortality in severely injured children receiving a massive transfusion. Prospective, multicenter studies are needed to determine optimal resuscitation strategies for these critically ill children.

BACKGROUND: Adhesive small bowel obstruction (ASBO) in children is generally managed with initial observation. However, no clear guidelines exist regarding indications to operate. Our purpose was to compare outcomes of ASBO management to determine whether timing of surgery and patient age should affect management. MATERIALS AND METHODS: A retrospective review of children admitted to a tertiary care children's hospital for ASBO between 2011 and 2015 was performed. Data included demographics, imaging, operative findings, and clinical management, which were analyzed using χ2 test, Fischer's exact test, t-test, analysis of variance, or logistic regression when appropriate. RESULTS: We identified 258 admissions for 202 patients. Urgent operation was performed in 12% and the rest had nonoperative management (NOM), which was successful in 54%. Patients younger than 1 y of age were more likely to require operation (odds ratio 3.71, 95% confidence interval [CI] 1.69-8.15; P < 0.01), and patients with prior ASBO were less likely to require operation (odds ratio 0.51, 95% CI 0.31-0.84; P < 0.01). At presentation, fever was most common in patients who had urgent operation (22.3% versus failure of NOM 7.6% versus successful NOM 6.6%; P = 0.02), but there were no differences in leukocytosis or abdominal pain. Excluding urgent operations, bowel resection was more common when operation was delayed more than 48 h (32.6% versus 15.3%; P = 0.04). CONCLUSIONS: In children with adhesive small bowel obstruction, NOM can be successful, but when failure is suspected, early operation before 48 h should be considered to avoid bowel loss, especially in children younger than 1 y of age.
