Purpose: We previously validated a visual aid for the use in the consent process for an appendectomy showing improved parental satisfaction and understanding. In this study, we evaluated provider satisfaction and perceived value of using the visual aid., Methods: An IRB approved survey was developed assessing provider experience with use of the visual aid. This was distributed and analyzed via Research Electronic Data Capture (RedCap) Database., Results: We administered 58 surveys (45% response rate). Participants included faculty (n = 2), fellows (n = 1), residents (n = 6), and physician assistants (n = 17). The visual aid was used >10 times by 50% of providers. The most common reason for not using the visual aid was not remembering it was available. Nearly half (40%) did not feel the visual aid added any time. 9/20 (45%) felt it added a small amount of time. Slightly over half of providers (52%) felt using the visual aid significantly increased family ability to give informed consent and made the consenting process easier for both providers and families., Conclusion: Using a visual aid in consenting families for appendectomy does not add significant time and subjectively improves the process for providers and increases provider perception of parental understanding., Level of Evidence: Cost effectiveness, Level IV., (Copyright © 2020 Elsevier Inc.

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 χ 2 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.

Background: The purpose of this study is to characterize the epidemiology, injury patterns, outcomes and trends of non-accidental trauma (NAT) in the United States using a large national database., Methods: Children <15 years presenting after NAT were identified in the 2007-2014 National Trauma Databank research datasets. Clinical and outcome data were analyzed using descriptive statistics, chi-square and logistic regression., Results: Of 678,503 children admitted for traumatic injuries, 3% (19,149) were victims of NAT. The majority (95%) were under 5 years and 71% under 1 year old. The majority (59%) were male. The median injury severity score (ISS) was 10 (IQR:5-19). African Americans were disproportionally affected (27% vs 17% of all traumas), and the majority had public or no insurance (85%). Incidence was highest in the midwest and lowest in the northeast regions of the country, although trends varied over time. NAT resulted in 43% of trauma deaths in children <1 year and 31% of trauma deaths in children <5. Traumatic brain injury (TBI) was the most commonly encountered diagnosis (50%). Polytrauma was common, and certain injury patterns were identified. Urgent operation was required in 6%, 43% were admitted to intensive care, and 9% died. Mortality was independently associated with TBI, thoracic injury, hollow viscus injury and older age., Conclusion: Non-accidental trauma is a leading cause of trauma mortality in young children. Multiple injuries are common, requiring comprehensive evaluation and early surgical involvement. The data presented in this study could serve as a guide to target injury prevention efforts., Level of Evidence: III STUDY TYPE: Prognostic and Epidemiological., (Copyright © 2019 Elsevier Inc.

Purpose: Clinical prediction of disease severity is important as one considers nonoperative management of simple appendicitis. This study assesses the accuracy of surgeons' prediction of appendicitis severity., Methods: From February to August 2016, pediatric surgeons at a single institution were asked to predict whether patients had simple or complex appendicitis preoperatively based on clinical data, imaging, and general assessment. Receiver operating characteristic curves were generated to determine area under the curve (AUC) and optimal cutoff points of clinical findings for diagnosing simple appendicitis. Outcomes included sensitivity and specificity of variables to identify simple appendicitis. Predictions were compared to operative findings using χ 2 . A p-value<0.05 was considered statistically significant., Results: Of 125 cases (median age 9 years [IQR 7-13], 58% male), simple appendicitis was predicted in 77 (62%) and complex appendicitis in 48 (38%). Predictions were accurate in 59 (77%) simple cases and 45 (94%) complex cases. Although surgeon prediction was more accurate than individual imaging or clinical findings and was highly sensitive (95%) for diagnosing simple appendicitis, specificity was only 71%. Lower WBC (<15.5 × 10 3 /μL, AUC 0.61, p = 0.05), afebrile (<100.4 °F, AUC 0.86, p < 0.01), and shorter symptom duration (≤ 1.5 days, AUC 0.71, p < 0.001) were associated with simple appendicitis. Of 18 complex cases (14%) inaccurately predicted as simple, 17 (94%) lacked diffuse tenderness, 15 (83%) were well-appearing, 11 (61%) had ultrasound findings of simple appendicitis, 11 (61%) had ≤2 days of symptoms, and 8 (44%) were afebrile (<100.4 °F)., Conclusion: While surgeon prediction of simple appendicitis is more accurate than ultrasound or clinical data alone, diagnostic accuracy is still limited., Type of Study: Prospective survey., Level of Evidence: II., (Copyright © 2019 Elsevier Inc.

Introduction:  The objective of this study was to evaluate the necessity of repeat imaging after an initial chest radiograph (CXR) following minimally invasive repair of pectus excavatum (MIRPE)., Materials and Methods:  A retrospective review was performed on patients who underwent MIRPE from January 2012 to July 2016 at two academic children's hospitals. Data collected included demographics, severity of pectus defect (Haller index [HI]), utilization of CXRs, outpatient follow-up, and clinical outcomes., Results:  A total of 360 patients (171 at Hospital 1 and 189 at Hospital 2) underwent MIRPE. Median age was 15.6 years and 84% were males. The median HI was 4.0. Median postoperative hospital length of stay was 4.2 days and median time to bar removal was 34 months. There was significant variation in postoperative imaging between the hospitals, including frequency of immediate postoperative CXR, total number of CXRs during hospitalization, and number of postoperative outpatient CXRs prior to bar removal. However, there was no significant difference in outcomes between the hospitals, including postoperative pneumothorax, postoperative chest tube placement, and complications., Conclusion:  These data suggest that increased repetitive imaging after an initial postoperative CXR does not affect clinical outcomes and may not be necessary after MIRPE., Competing Interests: None., (Georg Thieme Verlag KG Stuttgart · New York.)

Background: In adult trauma patients, high- and low-mortality trauma hospitals have similar rates of major complications but differ based on failure to rescue (mortality following a major complication), which has become a marker of hospital quality. The aim of this study is to examine whether failure to rescue is also an appropriate hospital quality indicator in pediatric trauma., Methods: Children younger than 15 years were identified in the 2007 to 2014 National Trauma Databank research data sets. Hospitals were classified as a high, average or low mortality based on risk-adjusted observed-to-expected in-hospital mortality ratios using the modified Trauma Mortality Probability Model. Regression modeling was used to explore the impact of hospital quality ranking on the incidence of major complications and failure to rescue., Results: Of 125,057 children, 31,600 were treated at low-mortality outlier hospitals, and 7,014 at high-mortality outlier hospitals. Low-mortality hospitals had a lower rate of major complications compared with high-mortality hospitals (0.5% [low] vs. 0.8% [high]; adjusted odds ratio [OR], 0.71; 95% confidence interval [CI], 0.61-0.83; p < 0.01) and a lower failure-to-rescue rate (17.6% [low] vs. 24.1% [high]; adjusted OR, 0.53 [high; 95% CI 0.34-0.83; p < 0.01]). When patients who died within 48 hours were excluded, low-mortality hospitals had a lower complication rate (OR, 0.81; 95% CI, 0.68, 0.96; p = 0.02), but similar failure-to-rescue rate compared to high-mortality hospitals. There was no correlation between trauma verification level and hospital mortality status based on the model., Conclusion: For pediatric trauma patients, mortality is more strongly associated with major complication rate than with failure to rescue. Thus, failure to rescue does not appear to be the key driver of hospital quality in this population as it does in the adult trauma population., Level of Evidence: Prognostic and epidemiological, level III.

Background: Peripancreatic fluid collection and pseudocyst development is a common sequela following non-operative management (NOM) of pancreatic injuries in children. Our purpose was to review management strategies and assess outcomes., Methods: A multicenter, retrospective review was conducted of children treated with NOM following blunt pancreatic injury at 22 pediatric trauma centers between the years 2010 and 2015. Organized fluid collections were called "acute peripancreatic fluid collection" (APFC) if identified < 4 weeks and "pseudocyst" if > 4 weeks following injury. Data analysis included descriptive statistics Wilcoxon rank-sum, Kruskal-Wallis and t tests., Results: One hundred patients with blunt pancreatic injury were identified. Median age was 8.5 years (range 1-16). Forty-two percent of patients (42/100) developed organized fluid collections: APFC 64% (27/42) and pseudocysts 36% (15/42). Median time to identification was 12 days (range 7-42). Most collections (64%, 27/42) were observed and 36% (15/42) underwent drainage: 67% (10/15) percutaneous drain, 7% (1/15) needle aspiration, and 27% (4/15) endoscopic transpapillary stent. A definitive procedure (cystogastrostomy/pancreatectomy) was required in 26% (11/42). Patients with larger collections (≥ 7.1 cm) had longer time to resolution. Comparison of outcomes in patients with observation vs drainage revealed no significant differences in TPN use (79% vs 75%, p = 1.00), hospital length of stay (15 vs 25 median days, p = 0.11), time to tolerate regular diet (12 vs 11 median days, p = 0.47), or need for definitive procedure (failure rate 30% vs 20%, p = 0.75)., Conclusions: Following NOM of blunt pancreatic injuries in children, organized fluid collections commonly develop. If discovered early, most can be observed successfully, and drainage does not appear to improve clinical outcomes. Larger size predicts prolonged recovery., Level of Evidence: III STUDY TYPE: Case series.

Background: High-resolution esophageal manometry (HREM) during laparoscopic Heller myotomy (LHM) with fundoplication for achalasia allows tailoring of myotomy length and wrap tightness. The purpose of this study is to quantify long-term postoperative symptom severity and quality of life using validated questionnaires., Methods: Children ≤18 years with achalasia who previously underwent LHM with intraoperative HREM from 2010 to 2017 were prospectively surveyed. Eckardt Symptom Score (ESS), Achalasia Severity Questionnaire (ASQ), Pediatric Quality of Life Inventory (PedsQL), and Pediatric GERD Symptom and Quality of Life (PGSQ) questionnaires were administered. Scores for historical controls were obtained from prior survey instrument validation studies as comparison., Results: Of 30 eligible patients, 12 (40%) completed the surveys. Mean age at time of surgery was 13 ± 3 years. Assessment was performed at least 10 months after surgery with mean time elapsed of 3.6 ± 2 years. Average premyotomy lower esophageal sphincter (LES) pressure, postmyotomy LES pressure, and postfundoplication LES pressure were 30 ± 10 mmHg, 14 ± 6 mmHg, and 18 ± 9, respectively. ESS (2.3/12), ASQ (39/100 ± 16), PGSQ (symptom: 0.6/4 ± 0.4, school: 0.4/4 ± 0.4), and overall PedsQL (82/100 ± 15) were similar to those of healthy historical controls., Conclusion: Children with achalasia undergoing LHM with intraoperative HREM had sustained long-term symptom improvement and quality of life scores comparable to healthy patients., Study and Level of Evidence: Retrospective, II., (Copyright © 2019 Elsevier Inc.

Purpose: The purpose of this study was to describe the epidemiology and evaluate the clinical significance of traumatic sternal fractures., Methods: Patients age ≤18 years with sternal fractures in the National Trauma Database research datasets from 2007-2014 were identified. Patient demographics, injuries, procedures, and outcomes were analyzed using descriptive statistics and logistic regression., Results: Three thousand one hundred sixty patients with sternal fracture were identified. Ninety percent of injuries occurred in patients between 12 and 18 years old. Median injury severity score (ISS) was 17 [9,29]. Exploratory thoracotomy was performed in 1%. Thirty-nine percent were admitted to the intensive care unit (ICU). On multivariate regression, predictors of ICU stay >1 day were increasing ISS, lack of the use of protective devices, decreasing Glasgow Coma Score (GCS), tachycardia, and pulmonary contusion. Median hospital length of stay was 4 [2, 9] days. In-hospital mortality was 8%. Predictors of mortality were lower GCS, increasing ISS, decreasing oxygen saturation, hypotension, and cardiac arrest. Use of protective devices and seat belts did not affect mortality., Conclusion: Sternal fractures in patients increase in incidence with age, and poor outcomes are impacted by associated injuries and complications. The presence of a sternal fracture should trigger a careful diagnostic evaluation., Level of Evidence: III STUDY TYPE: Treatment Study., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Purpose: Pediatric bowel preparation protocols used before colostomy reversal vary. The aim of this study is to determine institutional practices at our institution and evaluate the impact of bowel preparations on postoperative outcomes and hospital length of stay in children., Methods: This was a retrospective review of children ≤18 years old undergoing colostomy reversal at Texas Children's Hospital (TCH) between 12/2013 and 8/2017. Preoperative bowel regimens and outcomes were collected and analyzed using descriptive statistics, Wilcoxon Rank-Sum and Fishers Exact tests. Continuous variables are presented as median [IQR]., Results: Sixty-one children underwent colostomy reversal. Thirty-eight (62%) did not receive a preoperative bowel preparation. The two cohorts were similar in age, gender, and race. The most common indication for colostomy was anorectal malformation for thirty-seven (61%). Time from admission to surgery (19 h [17, 23] vs 3 [2, 3]; p < 0.01) and HLOS (6 days [5, 8] vs 5 [4, 6]; p = 0.02) were both longer in the bowel preparation cohort. Complications (3 [13%] vs 5 [22%]; p = 0.12) and 90-day readmissions (3 [13%] vs 6 [16%]; p = 0.64) were similar in both cohorts., Conclusion: Foregoing bowel preparation may have the potential to improve cost and reduce morbidity in children undergoing colostomy closure., Level of Evidence: III., Study Type: Treatment study., (Copyright © 2019.

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., (Copyright © 2018 Elsevier Inc.

Background: In patients requiring gastrostomies, ventriculoperitoneal (VP) shunts are a frequently encountered comorbidity. The objective of this study is to evaluate the postoperative management of children with VP shunts that undergo laparoscopic gastrostomy placement and determine their incidence of complications., Materials and Methods: Children 18 y old or younger who underwent laparoscopic gastrostomy placement at a freestanding academic children's hospital between January 2014 and October 2016 were reviewed. Data collected included demographics, management, and outcomes. Patients were compared based on their presence of a VP shunt before laparoscopic gastrostomy. Statistical analysis was performed using chi square, Fisher's exact, and Wilcoxon rank-sum tests., Results: We reviewed the medical records of 270 children that underwent laparoscopic gastrostomy placement by 15 pediatric surgeons. Of these, 9% (25) had a previously placed VP shunt. In comparing patients with a VP shunt with those without a VP shunt, there was no significant difference in median age (4 versus 3 y, P = 0.92), gender (48% versus 51% males, P = 0.80), body mass index (15 versus 16, P = 0.69), preoperative diet (48% versus 47% nasogastric tube dependent, P = 0.60), or procedure time (43 versus 42 min, P = 0.37). The postoperative management of these children was similar: day of initiation of postoperative feeds (84% versus 73% on postoperative day #1, P = 0.70), method of initiation of feeds (60% versus 55% continuous, P = 0.25), and type of initial feeds (83% versus 71% Pedialyte, P = 0.24). Similarly, there was no difference in hospital length of stay, return to the emergency department, or postoperative complications within 90 d (P > 0.05)., Conclusions: Children with ventriculoperitoneal shunts do not have a higher rate of immediate complications after laparoscopic gastrostomy placement and may be managed similar to other children in the postoperative period., (Copyright © 2018 Elsevier Inc.

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., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: Obtaining informed consent for surgical procedures is often compromised by patient and family educational background, complexity of the forms, and language barriers. We developed and tested a visual aid in order to improve the informed consent process for families of children with appendicitis., Methods: Families were randomized to receive either a standard surgical consent or a standard consent plus visual aid. Univariate and multivariate analyses were performed to assess the effectiveness of adding the visual aid to the consent procedure., Results: Parents in both cohorts were similar in age, gender and education level (p > 0.05). On multivariate analysis, visual consent had the strongest influence on parent/guardian comprehension (OR 4.0; 95%CI 2.2-7.2; p < 0.01), followed by post-secondary education (OR 2.7; 95%CI 1.5-4.9; p < 0.01), and use of external resources to look up appendicitis (OR 2.0; 95%CI 1.1-3.6; p = 0.02)., Conclusion: Visual aids improve understanding and retention of information given during the informed consent process of children with appendicitis., (Copyright © 2018 Elsevier Inc.

Purpose: Determining the integrity of the pancreatic duct is important in high-grade pancreatic trauma to guide decision making for operative vs non-operative management. Computed tomography (CT) is generally an inadequate study for this purpose, and magnetic resonance cholangiopancreatography (MRCP) is sometimes obtained to gain additional information regarding the duct. The purpose of this multi-institutional study was to directly compare the results from CT and MRCP for evaluating pancreatic duct disruption in children with these rare injuries., Methods: Retrospective study of data obtained from eleven pediatric trauma centers from 2010 to 2015. Children up to age 18 with suspected blunt pancreatic duct injury who had both CT and MRCP within 1 week of injury were included. Imaging findings of both studies were directly compared and analyzed using descriptive statistics, Chi square, Wilcoxon rank-sum, and McNemar's tests., Results: Data were collected for 21 patients (mean age 7.8 years). The duct was visualized more often on MRCP than CT (48 vs 5%, p < 0.05). Duct disruption was confirmed more often on MRCP than CT (24 vs 0%), suspected based on secondary findings equally (38 vs 38%), and more often indeterminate on CT (62 vs 38%). Overall, MRCP was not superior to CT for determining duct integrity (62 vs 38%, p = 0.28)., Conclusions: In children with blunt pancreatic injury, MRCP is more useful than CT for identifying the pancreatic duct but may not be superior for confirmation of duct integrity. Endoscopic retrograde cholangiogram (ERCP) may be necessary to confirm duct disruption when considering pancreatic resection., Level of Evidence: III.

Purpose: To review the outcomes of magnet ingestions from two children's hospitals and develop a clinical management pathway., Methods: Children <18years old who ingested a magnet were reviewed from 1/2011 to 6/2016 from two tertiary center children's hospitals. Demographics, symptoms, management and outcomes were analyzed., Results: From 2011 to 2016, there were 89 magnet ingestions (50 from hospital 1 and 39 from hospital 2); 50 (56%) were males. Median age was 7.9 (4.0-12.0) years; 60 (67%) presented with multiple magnets or a magnet and a second metallic co-ingestion. Suspected locations found on imaging were: stomach (53%), small bowel (38%), colon (23%) and esophagus (3%). Only 35 patients (39%) presented with symptoms and the most common symptom was abdominal pain (33%). 42 (47%) patients underwent an intervention, in which 20 (23%) had an abdominal operation. For those undergoing abdominal surgery, an exact logistic regression model identified multiple magnets or a magnet and a second metallic object co-ingestion (OR 12.9; 95% CI, 2.4 - Infinity) and abdominal pain (OR 13.0; 95% CI, 3.2-67.8) as independent risk factors., Conclusion: Magnets have a high risk of requiring surgical intervention for removal. Therefore, we developed a management algorithm for magnet ingestion., Level of Evidence: Level III., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Purpose: To review current management and outcomes of ingested batteries and develop a clinical management algorithm., Methods: Children <18years old who ingested a battery between 1/2011 and 9/2016 at two tertiary care children's hospitals were reviewed. Demographics, imaging, management and outcomes were analyzed using descriptive statistics, Chi-square and Wilcoxon Rank-sum tests., Results: There were 180 battery ingestions. The median age was 3.9 (range 0.7-18) years, with 78 (43%) males. The most common symptoms were abdominal pain (17%) and nausea/vomiting (14%). Diagnosis was confirmed with plain radiographs in 170 (94%) patients. Locations on imaging were: stomach (37%), small bowel (24%), esophagus (18%), colon (11%), and non-specific location past the gastroesophageal junction (9%). Treatment was dictated by five different subspecialties including surgery (35%), gastroenterology (25%), emergency medicine (19%), primary care/emergency with a consulting service (13%), and otolaryngology (8%). All esophageal batteries (n=33) had an intervention. Interventions included fluoroscopic balloon extraction (6 attempted, 33% retrieval rate), rigid esophagoscopy (26 attempted, 96% retrieval rate), and EGD (6 attempted, 83% retrieval rate). For batteries distal to the gastroesophageal junction 16 (11%) patients had an intervention. Interventions included EGD (13 patients, 69% retrieval), colonoscopy (1 patient, successful retrieval), and abdominal surgery in two patients., Conclusion: Isolated batteries that pass the gastroesophageal junction rarely require intervention and can be managed conservatively. Given the variability in managing these patients, we developed an evidence based algorithm., Level of Evidence: Level 2., Study Type: Retrospective Study., (Copyright © 2018 Elsevier Inc.

Significant progress has occurred medically for children who have experienced traumatic injuries; however, attention to their psychological adjustment has only more recently been a focus in research and clinical practice. These needs do not cease at discharge but, instead, require monitoring to determine whether further assessment and/or intervention are required. Our team, inclusive of the Psychology Service and the Trauma Service, identified 2 established screening measures (based on age) that were completed by patients during their outpatient follow-up visits postdischarge. Should a patient screen positive, the Trauma Service referred them to the Psychology Service for further evaluation and possible treatment (i.e., trauma-focused cognitive-behavioral therapy). Of 881 trauma activations, 31 (4%) patients were screened at an outpatient follow-up appointment through pediatric surgery/trauma clinic. Of these completed screening tools, 29% screened positive and warranted a referral to Psychology. Intervention was recommended for the majority of the patients evaluated; however, half of these did not return for this intervention. A collaboration between the Psychology Service and the Trauma Service is a vital step toward providing stepped care for patients after unintentional injuries. This allows for evaluation of patient needs and then a referral source to meet these identified needs. Future directions include increasing the number of screened patients, perhaps with use of technological supports (i.e., REDCap) or expansion into other clinics and consideration of ways to increase family's use of psychological intervention., Level of Evidence: Therapeutic/Care management Level IV.

Purpose: The objective of this study was to evaluate postoperative feeding regimens after laparoscopic gastrostomy placement and their effect on outcomes., Methods: Children 18 years of age or younger, who underwent laparoscopic gastrostomy placement at a tertiary-care academic children's hospital between January 2014 and October 2016, were reviewed. Data collected included patient characteristics, postoperative feeding regimen, and clinical outcomes. Statistical analysis was performed using Chi-square, Fisher's exact, and Wilcoxon Rank-Sum tests., Results: We reviewed the medical records of 270 children that underwent laparoscopic gastrostomy placement by 15 pediatric surgeons. The median age was 2.7 (interquartile range [IQR], 0.7-9.6) years, and 50% (n = 136) were male. The median body mass index was 15.5 (IQR, 14.0-17.5). Complications within 90 days included: granulation tissue (34%), leakage (17%), dislodgement (14%), and skin and soft-tissue infection (9%). Two patients returned to the operating room, 1 for a dislodged tube, and another for a volvulus within 10 days of gastrostomy tube placement. A subset analysis of outpatients that underwent elective laparoscopic gastrostomy placement showed variation in the day of initial feeds (0-2 postoperative days [POD]), method of initial feeds (continuous versus bolus) and choice of initial feeds (Pedialyte versus formula/breast milk). There was a significant difference in median hospital length of stay for early versus late initiation of feeds (POD 0: 2.1 days versus POD ≥1: 3.1 days, P < .01) without a difference in postoperative complications., Conclusion: There is substantial variation in the postoperative feeding regimen after laparoscopic gastrostomy. Initiation of early postoperative feeds may result in decreased length of stay without increasing complications.

Background/purpose: Endoscopic retrograde cholangiopancreatography (ERCP) is an adjunct for pediatric pancreatic injury management, but its use and utility in pediatric patients are unclear. We set out to evaluate the use of ERCP and its effects on outcomes., Methods: A retrospective review was performed for children who had pancreatic injuries at 22 pediatric trauma centers between 2010 and 2015. ERCP details and outcomes were collected. Analysis was performed using descriptive statistics and Wilcoxon rank-sum tests., Results: ERCP was used at 14/22 centers for 26 patients. Indications were duct evaluation, duct leak control, pseudocyst, fistula, and stricture. ERCP altered management or improved outcomes in 13/26 (50%), most commonly in patients with ERCP for duct evaluation, stricture, and fistula. In patients managed nonoperatively, those with early endoscopic intervention (within one week of injury) with stent or sphincterotomy (n=9) had similar time to regular diet [median (IQR)]: [10 (7-211) vs 7 (4-12) days; p=0.55], similar hospital days: [12 (8-20) vs 11 (6-19) days, p=0.63], and similar time on parenteral nutrition: [17 (10-40) vs 10 (6-18) days; p=0.19] compared to patients who were only observed., Conclusions: In children with blunt pancreatic injury, ERCP can be useful to diagnose duct injury and for management of late complications such as stricture and fistula. However, early endoscopic intervention for pancreatic duct disruption may not improve outcome or expedite recovery.

Background: Guidelines for nonoperative management (NOM) of high-grade pancreatic injuries in children have not been established, and wide practice variability exists. The purpose of this study was to evaluate common clinical strategies across multiple pediatric trauma centers to develop a consensus-based standard clinical pathway., Methods: A multicenter, retrospective review was conducted of children with high-grade (American Association of Surgeons for Trauma grade III-V) pancreatic injuries treated with NOM between 2010 and 2015. Data were collected on demographics, clinical management, and outcomes., Results: Eighty-six patients were treated at 20 pediatric trauma centers. Median age was 9 years (range, 1-18 years). The majority (73%) of injuries were American Association of Surgeons for Trauma grade III, 24% were grade IV, and 3% were grade V. Median time from injury to presentation was 12 hours and median ISS was 16 (range, 4-66). All patients had computed tomography scan and serum pancreatic enzyme levels at presentation, but serial enzyme level monitoring was variable. Pancreatic enzyme levels did not correlate with injury grade or pseudocyst development. Parenteral nutrition was used in 68% and jejunal feeds in 31%. 3Endoscopic retrograde cholangiopancreatogram was obtained in 25%. An organized peripancreatic fluid collection present for at least 7 days after injury was identified in 59% (42 of 71). Initial management of these included: observation 64%, percutaneous drain 24%, and endoscopic drainage 10% and needle aspiration 2%. Clear liquids were started at a median of 6 days (IQR, 3-13 days) and regular diet at a median of 8 days (IQR 4-20 days). Median hospitalization length was 13 days (IQR, 7-24 days). Injury grade did not account for prolonged time to initiating oral diet or hospital length; indicating that the variability in these outcomes was largely due to different surgeon preferences., Conclusion: High-grade pancreatic injuries in children are rare and significant variability exists in NOM strategies, which may affect outcomes and effective resource utilization. A standard clinical pathway is proposed., Level of Evidence: Therapeutic/care management, level V (case series).

Enzymatically isolated myocardial cells of Wistar rats were used to study contraction under the influence of ultrasound. The dynamics of sarcomere length were measured using a laser diffraction technique. The presence of continuous-wave ultrasound (f = 2.25 MHz, PSPTA = 0.3 MPa and f = 10 MHz, PSPTA = 0.15 MPa) did not cause any significant change in sarcomere dynamics (n = 21). However, it was shown that stimulation threshold could be decreased when ultrasound at 10 MHz was applied (14 of 22 cells). Low-frequency ultrasound was not able to cause these alterations. This effect was also found to be dependent on the distance between the sound transducer and the cells. Since temperature effects were negligible and cavitation was very unlikely under the given experimental conditions, we propose that acoustic streaming is responsible for the shift of stimulation threshold.

A new experimental approach has shown that human erythrocytes of different blood groups were induced to form more agglutinates at a sound pressure of 70-240 kPa in vitro than the control erythrocytes. Similar effects were observed for alcian blue and dextran stimulated aggregation and for spontaneous aggregation. The increase of agglutination or aggregation was reversible. Heating and acoustic cavitation were shown not to be responsible for this effect. Bulk fluid movement produced by ultrasound irradiation appeared to cause the described phenomenon. Possible underlying mechanisms connecting the acoustic streaming and agglutination or aggregation behaviour of the cells are proposed.

Measurements of the ultrasonic vibrational potentials (UVP) were performed at 815 kHz in agar and agarose gels as well as in several biological tissues from frog, rat and pig. The results for gels show that the magnitude of the UVP depends on the charge of the solid components of the gel, its mechanical strength and particularly on the concentration of free electrolytes present in the gel. The UVP decreases to less than 10 microV for a velocity amplitude of 1 cm/s if the salt concentrations exceed 10(-2) mol/L. The measurements in biological tissue in vitro demonstrate that the UVP are of the order of magnitude of a microV s cm-1 which is also explained by the presence of electrolytes of high concentrations in tissues. The measurements in biological tissue in vitro demonstrate that the UVP are of the order of magnitude of microV s cm-1 which is also explained by the presence of electrolytes of high concentrations in tissues. Based on these experiments, it can be concluded that the potential for harm to humans due to electrical effects of ultrasound as used in medical diagnostics is very low.
