Comparison of Outcomes Between Surveillance Ultrasound and Completion Lymph Node Dissection in Children and Adolescents With Sentinel Lymph Node-Positive Cutaneous Melanoma.

OBJECTIVE: To determine the impact of nodal basin ultrasound (US) surveillance versus completion lymph node dissection (CLND) in children and adolescents with sentinel lymph node (SLN) positive melanoma. BACKGROUND: Treatment for children and adolescents with melanoma are extrapolated from adult trials. However, there is increasing evidence that important clinical and biological differences exist between pediatric and adult melanoma. METHODS: Patients ≤18 years diagnosed with cutaneous melanoma between 2010 and 2020 from 14 pediatric hospitals were included. Data extracted included demographics, histopathology, nodal basin strategies, surveillance intervals, and survival information. RESULTS: Of 252 patients, 90.1% (n=227) underwent SLN biopsy (SLNB), 50.9% (n=115) had at least 1 positive node. A total of 67 patients underwent CLND with 97.0% (n=65/67) performed after a positive SLNB. In contrast, 46 total patients underwent US observation of nodal basins with 78.3% (n=36/46) of these occurring after positive SLNB. Younger patients were more likely to undergo US surveillance (median age 8.5 y) than CLND (median age 11.3 y; P =0.0103). Overall, 8.9% (n=21/235) experienced disease recurrence: 6 primary, 6 nodal, and 9 distant. There was no difference in recurrence (11.1% vs 18.8%; P =0.28) or death from disease (2.2% vs 9.7%; P =0.36) for those who underwent US versus CLND, respectively. CONCLUSIONS: Children and adolescents with cutaneous melanoma frequently have nodal metastases identified by SLN. Recurrence was more common among patients with thicker primary lesions and positive SLN. No significant differences in oncologic outcomes were observed with US surveillance and CLND following the identification of a positive SLN.

Management and Outcomes of Wilms Tumor With Suprarenal Intravascular Extension: A Pediatric Surgical Oncology Research Collaborative Study.

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.

Use of modern three-dimensional imaging models to guide surgical planning for local control of pediatric extracranial solid tumors.

INTRODUCTION: In complex pediatric surgical oncology, surgical planning is contingent upon data gathered from preoperative imaging. Three-dimensional (3D) modeling and printing has been shown to be beneficial for adult presurgical planning, though pediatric literature is less robust. The study reviews our institutional experience with the use of 3D image segmentation and printed models in approaching resection of extracranial solid tumors in children. METHODS: This is a single institutional series from 2021 to 2023. Models were based on computed tomography and magnetic resonance imaging studies, optimized for 3D imaging. The feasibility and creation of the models is reviewed, including specific techniques, software, and printing materials from our institution. Clinical implications for surgical planning are also described, along with detailed preoperative and intraoperative images. RESULTS: 3D modeling and printing was performed for four pediatric patients diagnosed with extracranial solid tumors. Diagnoses included Ewing sarcoma, hepatoblastoma, synovial sarcoma, and osteosarcoma. No intraoperative complications or discrepancies with the preoperative 3D-printed model were noted. No evidence of local recurrence was identified in any patient thus far. CONCLUSION: Our institutional series demonstrates a wide spectrum of clinical application for 3D modeling and printing technology within pediatric surgical oncology. This technology may aid in surgical planning for both resection and reconstruction, can be applied to a diverse breadth of diagnoses, and may potentially augment patient and/or family education about their condition.

Survival outcomes in pediatric patients with metastatic Ewing sarcoma who achieve a rapid complete response of pulmonary metastases.

PURPOSE: Our objectives were to compare overall survival (OS) and pulmonary relapse between patients with metastatic Ewing sarcoma (EWS) at diagnosis who achieve rapid complete response (RCR) and those with residual pulmonary nodules after induction chemotherapy (non-RCR). PATIENTS AND METHODS: This retrospective cohort study included children under 20 years with metastatic EWS treated from 2007 to 2020 at 19 institutions in the Pediatric Surgical Oncology Research Collaborative. Chi-square tests were conducted for differences among groups. Kaplan-Meier curves were generated for OS and pulmonary relapse. RESULTS: Among 148 patients with metastatic EWS at diagnosis, 61 (41.2%) achieved RCR. Five-year OS was 71.2% for patients who achieved RCR, and 50.2% for those without RCR (p = .04), and in multivariable regression among patients with isolated pulmonary metastases, RCR (hazards ratio [HR] 0.42; 95% confidence interval [CI]: 0.17-0.99) and whole lung irradiation (WLI) (HR 0.35; 95% CI: 0.16-0.77) were associated with improved survival. Pulmonary relapse occurred in 57 (37%) patients, including 18 (29%) in the RCR and 36 (41%) in the non-RCR groups (p = .14). Five-year pulmonary relapse rates did not significantly differ based on RCR (33.0%) versus non-RCR (47.0%, p = .13), or WLI (38.8%) versus no WLI (46.0%, p = .32). DISCUSSION: Patients with EWS who had isolated pulmonary metastases at diagnosis had improved OS if they achieved RCR and received WLI, despite having no significant differences in rates of pulmonary relapse.

Disparities in insurance status negatively affect patients with infantile hypertrophic pyloric stenosis.

PURPOSE: Infantile hypertrophic pyloric stenosis (IHPS) is suspected to have worse outcomes when length of illness prior to presentation is prolonged. Our objective was to evaluate how social determinants of health influence medical care and outcomes for babies with IHPS. METHODS: A retrospective review was performed over 10 years. Census data were used as proxy for socioeconomic status via Geo-Identification codes and correlated with food access and social vulnerability variables. The cohort was subdivided to understand the impact of Medicaid Managed Care (MMC). RESULTS: The cohort (279 cases) was divided into two groups; early group from 2011 to 2015 and late from 2016 to 2021. Cases in the late group were older at the time of presentation (41.5 vs. 36.5 days; p = 0.022) and presented later in the disease course (12.8 vs. 8.9 days; p = 0.021). There was no difference in race (p = 0.282), gender (p = 0.874), or length of stay. CONCLUSIONS: Patients who presented with IHPS after implementation of phased MMC were older, had a longer symptomatic course, and shorter pylorus measurements. Patients with public insurance after the implementation of MMC were more likely to follow-up with an outpatient pediatrician within a month of hospitalization. These results suggest that MMC may have improved access to care for infants with IHPS.

Exploring Limited English Proficiency in the Clinical Outcomes of Pediatric Burn Patients.

INTRODUCTION: Limited English proficiency (LEP) is linked to lower health care access and worse clinical outcomes. This study aims to explore the potential role of LEP on clinical outcomes of pediatric burn patients. METHODS: We conducted a single-institution retrospective study of burn patients presenting at a tertiary pediatric burn referral program between January 2016 and December 2020. Patient demographics, burn mechanism, severity, interventions, and primary patient language were abstracted from the electronic health record. Clinical outcomes (length of stay [LOS], clinic follow-up, and 30-day readmission) of patients with LEP were compared to patients with English as primary language (EPL). RESULTS: Thirty-five (4.2%) patients with LEP were identified of 840 total patients. On univariate analysis, there was no difference in mean total body surface area (6.5% versus 6.1%), report of physical abuse (2.9% versus 8.9%), or need for grafting (14.3% versus 15.0%) comparing patients with LEP to those with EPL. Patients with LEP were more likely to have a scald burn (68.6% versus 48.9%, P = 0.025) and less likely to have a flame/fire burn (20.0% versus 37.6%, P = 0.047). On multivariate analysis, there was no difference between patients with LEP compared to patients with EPL for LOS (2.9 versus 3.5 d), 30-day readmissions (5.6% versus 5.7%), or clinic follow-up (80.6% versus 75.0%). In patients with >10% total body surface area, patients with LEP had a longer emergency department LOS (277 min versus 145 min, P = 0.06) but no difference in outcome measures. CONCLUSIONS: Pediatric patients with LEP were not found to have worse burn outcomes compared to EPL patients in our patient sample. However, a true association is difficult to determine given the small sample size of LEP patients and the potential underestimation of language discordancy as recorded in the electronic medical record. Further research is needed to better explore the role of primary language and health communication as a social determinant of health in pediatric burn patients.

Retrospective review of antimicrobial use for gastroschisis patients in Kigali, Rwanda: can improved stewardship reduce late inpatient deaths?

Gastroschisis mortality is 75-100% in low-resource settings. In Rwanda, late deaths are often due to sepsis. We aimed to understand the effect of antimicrobial use on survival. We conducted a retrospective review of gastroschisis patients at a tertiary hospital in Kigali, Rwanda between January 2016-June 2019. Demographics, antimicrobial use, microbiology, and outcomes were abstracted. Descriptive and univariate analyses were conducted to assess factors associated with improved survival. Among 92 gastroschisis patients, mortality was 77%(n = 71); 23%(n = 21) died within 48 h. 98%(n = 90) of patients received antibiotics on arrival. Positive blood cultures were obtained in 41%(n = 38). Patients spent 86%(SD = 20%) of their hospital stay on antibiotics and 38%(n = 35) received second-line agents. There was no difference in age at arrival, birth weight, gestational age, silo complications, or antimicrobial selection between survivors and non-survivors. Late death patients spent more total hospital days and post-abdominal closure days on antibiotics (p < 0.001) compared to survivors. There was no difference in the proportion of hospital stay on second-line antibiotics (p = 0.1). CONCLUSION: We identified frequent late deaths, prolonged antibiotic courses, and regular use of second-line antibiotic agents in this retrospective cohort of Rwandan gastroschisis patients. Future studies are needed to evaluate antimicrobial resistance in pediatric surgical patients in Rwanda. WHAT IS KNOWN: • Global disparities in gastroschisis outcomes are extreme, with <4% mortality in high-income settings and 75-100% mortality in low-income settings. • Antimicrobial surveillance data is sparse across Africa, but existing evidence suggests high levels of resistance to first-line antibiotics in Rwanda. WHAT IS NEW: • In-hospital survival for gastroschisis was 23% from 2016-2019 and most deaths occurred late (>48hrs after admission) due to sepsis. • Rwandan gastroschisis patients received prolonged courses of antibiotics and second-line antibiotics were frequently used without culture data, raising concern for antimicrobial resistance.

Incidence and management of pleural effusions in patients with Wilms tumor: A Pediatric Surgical Oncology Research Collaborative study.

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.

Global Surgery Opportunities for General Surgery Residents: Are We Making Progress?

INTRODUCTION: Global surgery efforts have significantly expanded in the last decade. While an increasing number of general surgery residents are incorporating global surgery experiences and research into their training, few resources are available for residency applicants to evaluate opportunities at programs to which they are applying. MATERIALS AND METHODS: A 17-question survey of all general surgery residency program directors (PDs) was conducted by the Global Surgery Student Alliance through emails to the Association of Program Directors in Surgery listserv. PDs indicated if they wished to remain anonymous or include program information in an upcoming online database. RESULTS: Two hundred fifty eight general surgery PDs were emailed the survey and 45 (17%) responses were recorded. Twenty eight (62%) programs offered formal global surgery experiences for residents, including clinical rotations, research, and advocacy opportunities. Thirty one (69%) programs were developing a global health center. Forty two (93%) respondents indicated that global surgery education was an important aspect of surgical training. Barriers to global surgery participation included a lack of funding, time constraints, low faculty participation, and minimal institutional interest. CONCLUSIONS: While most respondents felt that global surgery was important, less than two-thirds offered formal experiences. Despite the significant increase in public awareness and participation in global surgery, these numbers remain low. While this study is limited by a 17% response rate, it demonstrates that more efforts are needed to bolster training, research, and advocacy opportunities for surgical trainees and promote a global perspective on healthcare.

Medical Student Career Choice: Who Is the Influencer?

BACKGROUND: While many factors influence medical student career choice, interactions with attending and resident physicians during clinical rotations are particularly important. To evaluate the influence of attending and resident physicians on medical students' career choices, particularly for those pursuing surgical careers, we quantified their respective influence in the context of other known influences. METHODS: Rising fourth-year medical students and new graduates were given an IRB-exempt, 14-item online survey. Descriptive statistics were performed on the demographic information. Chi-square analysis was used, as were Kruskal-Wallis and Mann-Whitney analyses on the Likert responses (α = 0.05). RESULTS: Survey response was 24%. Students pursuing general surgery rated residents greater than or equal to attendings on 7 of 8 key mentoring characteristics. Of students choosing a different specialty than the one they intended to pursue upon entering medical school, the influence of residents was cited by 100% of the students pursuing general surgery, compared to 59% of the entire cohort. Identification of a role model and perceived personality fit were significantly more important than other factors (P < 0.0001). Students pursuing general surgery rated the importance of identifying a role model and perceived personality fit greater than their peers. CONCLUSIONS: Residents have greater influences on medical students' career choice compared to attendings. Students pursuing a surgical specialty, particularly general surgery, considered the influence of role models and perceived personality fit to be the most important factors in their specialty decision. These findings provide valuable insights to improve student experiences and career recruitment in surgical specialties, particularly general surgery.

Predictors of Survival: A Retrospective Review of Gastroschisis and Intestinal Atresia in Rwanda.

INTRODUCTION: Neonatal surgical diseases are prime examples of the global disparity in surgical access and outcomes, with survival for conditions like gastroschisis reaching above 95% in high-income settings but usually fatal in low-income settings. This study aims to examine outcomes and predictors of mortality in patients with two specific neonatal surgical conditions that often require early transfer and prolonged inpatient care (gastroschisis and intestinal atresia) at Rwanda's main pediatric referral hospital. METHODS: A single-institution retrospective chart review of neonates with gastroschisis and intestinal atresia was conducted between January 2016 and June 2019. Abstracted data included demographics, referral history, admission interventions, operative details, in-hospital complications, nutrition patterns, length of stay, and mortality. Daily logs were created to evaluate feeding status, infection status, and antibiotic usage. Descriptive and univariate analysis was conducted, with the primary outcome being survival to hospital discharge. RESULTS: A total of 112 patients met inclusion criteria (82% gastroschisis [n = 92] and 18% intestinal atresia [n = 20]). Median age at arrival was 0 d (GS) [IQR 0-1 d] and 8.5 d (IA) [IQR 4-10 d] (P < 0.0001). Survival to discharge was 22.8% (GS) (n = 21) and 60% (IA) (n = 12) with a mean length of stay of 28.3 d (GS) and 18.4 d (IA). The median number of days to initiation of oral feeds was 8.5 d [IQR 7-11] for gastroschisis survivors. CONCLUSIONS: Neonatal surgical conditions that require early transfer and prolonged nutritional intervention are challenging in low-resource settings, but through treatment by a comprehensive pediatric surgical service, improving survival is possible.

Should We Offer Surgery for Biliary Atresia in Low-Resource Settings? Surgical Outcomes in Rwanda.

BACKGROUND: In many resource-limited settings, patients with biliary atresia present too late for surgical correction to be offered, and the diagnosis is fatal. As pediatric surgical and anesthesia capabilities have improved, patients in Rwanda have been offered surgical exploration. This study explores initial outcomes. METHODS: Patients presenting with direct hyperbilirubinemia and clinical suspicion of biliary atresia were identified at the main university teaching hospital in Kigali, Rwanda, from January 2016 to June 2019. Patient demographics, referral history, geographic location, preoperative imaging, preoperative laboratory studies, operative details, postoperative laboratory studies, in-hospital complications, length of stay, and survival were abstracted from retrospective chart review. Descriptive analysis was performed, and univariate analysis evaluated survival and complications. RESULTS: Seventeen patients were identified with biliary atresia, and thirteen were offered surgery. The median age of admission was 77 d (interquartile range [IQR] 63-92 d), with the median time wait for the operation being 19 d (IQR 9-27 d). The median age at operation was 93 d (IQR 76-123 d). In-hospital postoperative mortality was 15.4% (n = 2) and postoperative complications occurred in 46.2% (n = 6). Eleven patients survived to hospital discharge (84.6%), with a median length of stay of 8 d (IQR 6-13 d). CONCLUSIONS: While future studies are needed to evaluate the long-term outcomes, this series shows that surgical treatment of biliary atresia can be safely performed in Rwanda. Early referral of direct hyperbilirubinemia is essential, particularly as limited resources and personnel may impact the time from diagnosis to operation.

Distal rectal skip segment Hirschsprung disease: Case report and review of literature.

Background: Lack of ganglion cells on adequate suction rectal biopsy is the gold standard for diagnosis of neonatal Hirschsprung disease (HD), and the presence of ganglion cells precludes such a diagnosis. Case report: A 10-day old male neonate presented with clinical symptoms concerning for HD. However, suction rectal biopsies demonstrated submucosal ganglion cells on the distal suction rectal biopsies (2 cm from anal verge) and not on the proximal (3 cm from anal verge), with similar findings on repeat biopsies. Clinical suspicion remained high, and diagnostic laparoscopy with intraoperative biopsies confirmed aganglionosis with a sigmoid transition. A pull through resection confirmed the diagnosis of distal rectal skip segment HD (SSHD) with a ∼6 cm length of circumferential aganglionosis extending into the proximal sigmoid. Conclusions: Discordant results on suction rectal biopsies should raise the possibility of SSHD. Awareness of the entity can facilitate timely definitive management in neonatal period.

Injury, disability and access to care in Rwanda: results of a nationwide cross-sectional population study.

BACKGROUND: Disparities in access to quality injury care are a growing concern worldwide, with over 90 % of global injury-related morbidity and mortality occurring in low-income countries. We describe the use of a survey tool that evaluates the prevalence of surgical conditions at the population level, with a focus on the burden of traumatic injuries, subsequent disabilities, and barriers to injury care in Rwanda. METHODS: The Surgeons OverSeas Assessment of Surgical Need (SOSAS) tool is a cross-sectional, cluster-based population survey designed to measure conditions that may necessitate surgical consultation or intervention. Questions are structured anatomically and designed around a representative spectrum of surgical conditions. Households in Rwanda were sampled using two-stage cluster sampling, and interviews were conducted over a one-month period in 52 villages nationwide, with representation of all 30 administrative districts. Injury-related results were descriptively analyzed and population-weighted by age and gender. RESULTS: A total of 1,627 households (3,175 individuals) were sampled; 1,185 lifetime injury-related surgical conditions were reported, with 38 % resulting in some form of perceived disability. Of the population, 27.4 % had ever had a serious injury-related condition, with 2.8 % having an injury-related condition at the time of interview. Over 30 % of household deaths in the previous year may have been surgically treatable, but only 4 % were injury-related. CONCLUSIONS: Determining accurate injury and disability burden is crucial to health system planning in low-income countries. SOSAS is a useful survey for determining injury epidemiology at the community level, which can in turn help to plan prevention efforts and optimize provision of care.

Can focused trauma education initiatives reduce mortality or improve resource utilization in a low-resource setting?

BACKGROUND: Over 90% of injury deaths occur in low-income countries. Evaluating the impact of focused trauma courses in these settings is challenging. We hypothesized that implementation of a focused trauma education initiative in a low-income country would result in measurable differences in injury-related outcomes and resource utilization. METHODS: Two 3-day trauma education courses were conducted in the Rwandan capital over a one-month period (October-November, 2011). An ATLS provider demonstration course was delivered to 24 faculty surgeons and 15 Rwandan trauma nurse auditors, and a Canadian Network for International Surgery Trauma Team Training (TTT) course was delivered to 25 faculty, residents, and nurses. Trauma registry data over the 6 months prior to the courses were compared to the 6 months afterward with emergency department (ED) mortality as the primary endpoint. Secondary endpoints included radiology utilization and early procedural interventions. Univariate analyses were conducted using χ(2) and Fisher's exact test. RESULTS: A total of 798 and 575 patients were prospectively studied during the pre-intervention and post-intervention periods, respectively. Overall mortality of injured patients decreased after education implementation from 8.8 to 6.3%, but was not statistically significant (p = 0.09). Patients with an initial Glasgow Coma Score (GCS) of 3-8 had the highest injury-related mortality, which significantly decreased from 58.5% (n = 55) to 37.1% (n = 23), (p = 0.009, OR 0.42, 95% CI 0.22-0.81). There was no statistical difference in the rates of early intubation, cervical collar use, imaging studies, or transfusion in the overall cohort or the head injury subset. When further stratified by GCS, patients with an initial GCS of 3-5 in the post-intervention period had higher utilization of head CT scans and chest X-rays. CONCLUSIONS: The mortality of severely injured patients decreased after initiation of focused trauma education courses, but no significant increase in resource utilization was observed. The explanation may be complex and multi-factorial. Long-term multidisciplinary efforts that pair training with changes in resources and mentorship may be needed to produce broad and lasting changes in the overall care system.

Prevalence of breast masses and barriers to care: results from a population-based survey in Rwanda and Sierra Leone.

BACKGROUND AND OBJECTIVES: Breast cancer incidence may be increasing in low- and middle-income countries (LMIC). This study estimates the prevalence of breast masses in Rwanda (RW) and Sierra Leone (SL) and identifies barriers to care for women with breast masses. only. METHODS: Data were collected from households in RW and SL using Surgeons Overseas Assessment of Surgical Need (SOSAS), a cross-sectional, randomized, cluster-based population survey designed to identify surgical conditions. Data regarding breast masses and barriers to care in women with breast masses were analyzed. RESULTS: 3,469 households (1,626 RW; 1,843 SL) were surveyed and 6,820 persons (3,175 RW; 3,645 SL) interviewed. Breast mass prevalence was 3.3% (SL) and 4.6% (RW). Overall, 93.8% of masses were in women, with 49.1% (SL) and 86.1% (RW) in women >30 years. 73.7% (SL) and 92.4% (RW) of women reported no disability; this was their primary reason for not seeking medical attention. Overall, 36.8% of women who reported masses consulted traditional healers only. CONCLUSIONS: For women in RW and SL, minimal education, poverty, and reliance on traditional healers are barriers to medical care for breast masses. Public health programs to increase awareness and decrease barriers are necessary to lower breast cancer mortality rates in low- and middle-income countries (LMIC).

The unnecessary workups and admissions of adolescents and young adults with spontaneous pneumomediastinum.

Spontaneous pneumomediastinum (SPM) is a rare condition in children and young adults that raises concern for esophageal perforation or extension of an air leak, resulting in admissions with multiple interventions performed. To assess our outcomes, and to evaluate our resource utilization, we reviewed our experience with SPM. We conducted a retrospective review of SPM cases in patients aged 5-25 years old occurring between 2011 and 2021 at a single academic tertiary care center. Clinical, demographic, and outcome variables were collected and analyzed, and cohorts were compared using Fischer's Exact Test and Welch's T Test. 166 SPM cases were identified-all of which were Emergency Department (ED) presentations. 84% of the cases were admitted. 70% had Computerized Tomography (CT) scans, with no defined criteria for imaging. Comparison of floor admissions with discharges from the ED showed no significant difference in presenting symptoms, demographics, or outcomes between the two groups. Recurrence was noted in 4 patients with a range of 5.9 months-4.9 years from the initial episode. In the largest SPM study in the pediatric and young adult population, we noted no significant difference in management or outcomes in admitted or ED discharge patients nor those with CT imaging. Our results suggest that a large number of SPM can be managed safely with discharge from the ED.

The Impact of Educational Materials on Parental Anxiety and Productivity: A Clinical Trial in Pediatric Appendicitis.

OBJECTIVES: There is limited literature on how acute appendicitis, the most common acute children's surgical illness, affects the family. We conducted a prospective study to assess the impact of educational materials on parents' anxiety and productivity during the child's illness. METHODS: A quasi-experimental clinical trial was conducted among parents of children undergoing laparoscopic appendectomy. In Phase I, parents received the standard explanations at diagnosis and throughout the postoperative period. In Phase II, parents also received a comprehensive educational brochure on pediatric appendicitis at diagnosis. The primary outcome, parental preoperative anxiety, was assessed using the Amsterdam Preoperative Anxiety and Information Scale (APAIS). The secondary outcome, parental productivity, was evaluated through a post-recovery online questionnaire based on the Productivity and Disease Questionnaire (PRODISQ). Baseline characteristics and outcomes were compared between the two cohorts using t-tests, Mann-Whitney, chi-square, or Fischer's exact test as appropriate. RESULTS: Phases I and II included 67 and 66 families, respectively. Patient demographics and disease severity were similar between both groups. Of the 53 parents (80.3%) in Phase II who answered the postoperative questionnaire, most recommended the booklet (96.2%), as it decreased their stress (78.0%) and enhanced their understanding of appendicitis (94.1%). However, the two groups showed similar preoperative anxiety levels and postoperative productivity loss. CONCLUSIONS: Educational materials increased satisfaction with surgical care but did not mitigate the high parental preoperative anxiety levels and postoperative productivity loss. Additional research is required to elucidate interventions that may improve these important patient and family-centered outcomes. TYPE OF STUDY: Non-Randomized Clinical Trial. LEVEL OF EVIDENCE: II.

Social determinants of health in pediatric trauma: Associations with injury mechanisms and outcomes in the context of the COVID-19 pandemic.

BACKGROUND: Relationships between social determinants of health and pediatric trauma mechanisms and outcomes are unclear in context of COVID-19. METHODS: Children <16 years old injured between 2016 and 2021 from ten pediatric trauma centers in Florida were included. Patients were stratified by high vs. low Social Vulnerability Index (SVI). Injury mechanisms studied were child abuse, ATV/golf carts, and firearms. Mechanism incidence trends and mortality were evaluated by interrupted time series and multivariable logistic regression. RESULTS: Of 19,319 children, 68% and 32% had high and low SVI, respectively. Child abuse increased across SVI strata and did not change with COVID. ATV/golf cart injuries increased after COVID among children with low SVI. Firearm injuries increased after COVID among children with high SVI. Mortality was predicted by injury mechanism, but was not independently associated with SVI, race, or COVID. CONCLUSION: Social vulnerability influences pediatric trauma mechanisms and COVID effects. Child abuse and firearm injuries should be targeted for prevention.

Golf cart injuries have similar severity to all-terrain vehicle injuries in children: a multicenter comparison over a 5-year period.

Background: Golf carts (GCs) and all-terrain vehicles (ATVs) are popular forms of personal transport. Although ATVs are considered adventurous and dangerous, GCs are perceived to be safer. Anecdotal experience suggests increasing numbers of both GC and ATV injuries, as well as high severity of GC injuries in children. This multicenter study examined GC and ATV injuries and compared their injury patterns, resource utilization, and outcomes. Methods: Pediatric trauma centers in Florida submitted trauma registry patients age <16 years from January 2016 to June 2021. Patients with GC or ATV mechanisms were identified. Temporal trends were evaluated. Injury patterns, resource utilization, and outcomes for GCs and ATVs were compared. Intensive care unit admission and immediate surgery needs were compared using multivariable logistic regression. Results: We identified 179 GC and 496 ATV injuries from 10 trauma centers. GC and ATV injuries both increased during the study period (R2 0.4286, 0.5946, respectively). GC patients were younger (median 11 vs 12 years, p=0.003) and had more intracranial injuries (34% vs 19%, p<0.0001). Overall Injury Severity Score (5 vs 5, p=0.27), intensive care unit (ICU) admission (20% vs 16%, p=0.24), immediate surgery (11% vs 11%, p=0.96), and mortality (1.7% vs 1.4%, p=0.72) were similar for GCs and ATVs, respectively. The risk of ICU admission (OR 1.19, 95% CI 0.74 to 1.93, p=0.47) and immediate surgery (OR 1.04, 95% CI 0.58 to 1.84, p=0.90) remained similar on multivariable logistic regression. Conclusions: During the study period, GC and ATV injuries increased. Despite their innocuous perception, GCs had a similar injury burden to ATVs. Heightened safety measures for GCs should be considered. Level of evidence: III, prognostic/epidemiological.
