FireSync EMS: A Novel Mobile Application for Burn Surface Area Calculation.

The percent total body surface area burned is a critical determinant of the required level of care, initial management, and prognosis in burn patients. The current gold standard for estimating this measurement, the Lund-Browder chart, requires familiarity with its construction and may not be practical for use by first responders in the field. In this study, we present a novel burn surface area calculator mobile application developed for first responders and validate its accuracy. Infant, pediatric, and adult manikins were fabricated with eight simulated burns of varying sizes and distributions. 42 pre-clinical medical students and firefighters were tasked with estimating the total body surface area of each burn using both the FireSync-EMS app and Lund-Browder chart. Univariate analysis and mixed-effects linear regression modeling were performed to compare the accuracy of both methods in relation to user experience, manikin size, and burn size. FireSync-EMS significantly reduced overestimation bias (0.11%, SD 2.33 versus 0.91%, SD 4.12, p = 0.002), particularly for burns on child-size manikins (p < 0.001) and burns involving <10% (p = 0.005) and >20% (p = 0.030) total body surface area. Multivariable modeling revealed that the Lund-Browder chart was an independent determinant of the magnitude of estimation error, with a 1.19 times multiplicative effect relative to FireSyncEMS (p < 0.001). Participants overwhelmingly found FireSync-EMS easier, more intuitive, faster, and preferable (p < 0.001 for all). FireSync-EMS may be an easier, faster, and more accurate alternative to the Lund-Browder chart for estimation of the total body surface area burned.

A Nationwide Analysis of the Impact of Cardiopulmonary Anomalies on Cleft Palate Surgical Outcomes.

OBJECTIVE: To increase awareness and improve perioperative care of patients with cleft palate (CP) and coexisting cardiopulmonary anomalies. DESIGN: Retrospective cohort. SETTING: Multi-center. PATIENTS/PARTICIPANTS: Patients who underwent surgical repair of CP between 2012-2020 identified in the American College of Surgeons National Surgical Quality Improvement Program Pediatric Data File. Chi-squared analysis and Student's t-test were implemented to make associations between congenital heart disease (CHD) and congenital pulmonary disease (CPD) and postoperative complications. Multiple logistic regression was performed to identify associations between CP and CHD/CPD while controlling for age, gender, and ASA class. C2 values were used to assess the logistic regressions, with a significance level of 0.05 indicating statistical significance. MAIN OUTCOMES MEASURES: Length of stay (LOS), perioperative complications (readmission, reoperation, reintubation, wound dehiscence, cerebrovascular accidents, and mortality). RESULTS: 9 96 181 patients were identified in the database, 17 786 of whom were determined to have CP, of whom 16.0% had congenital heart defects (CHD) and 13.2% had congenital pulmonary defects (CPD). Patients with CHD and CPD were at a significantly greater risk of increased LOS and all but one operative complication rate (wound dehiscence) relative to patients with CP without a history of CHD and CPD. CONCLUSION: This study suggests that congenital cardiopulmonary disease is associated with increased adverse outcomes in the setting of CP repair. Thus, heightened clinical suspicion for coexisting congenital anomalies in the presence of CP should prompt referring providers to perform a comprehensive and multidisciplinary evaluation to ensure cardiopulmonary optimization prior to surgical intervention.

A National Analysis of Craniosynostosis Demographic and Surgical Trends Over a 10-Year Period.

The pathogenesis of craniosynostosis, characterized by the premature fusion of calvarial sutures, is multifaceted and often the result of an amalgamation of contributing factors. The current study seeks examine the possible contributors to craniosynostosis development and its surgical trends over time. A multicenter/national retrospective cohort study was conducted of patients who underwent surgical repair of craniosynostosis (n=11,279) between 2012 and 2021 identified in the American College of Surgeons National Surgical Quality Improvement Program Pediatric Data File. Main outcome measures included risk factors and trends relating to surgical repair of craniosynostosis. Nationwide reports of craniosynostosis in the NSQIP-P database have increased between 2012 and 2021 by 195%. The prevalence of craniosynostosis per overall cases has remained between 1.0% and 1.3%. There were predominantly more White male patients in the craniosynostosis cohort (P<0.001). Craniosynostosis patients had significantly greater birth weights, gestational ages, and were less likely to be premature (P<0.05). Linear regression demonstrated that operative time, anesthesia time, and length of stay significantly decreased over the study period (P<0.001). This national data analysis highlights trends in craniosynostosis repair indicating potential improvements in safety and patient outcomes over time. While these findings offer insights for health care professionals, caution is warranted in extrapolating beyond the data's scope. Future research should focus on diverse patient populations, compare outcomes across institutions, and employ prospective study designs to enhance the evidence base for craniosynostosis management. These efforts will help refine diagnostic and treatment strategies, potentially leading to better outcomes for patients.

Endoscopic Tissue Expander Implantation in Post-Burn Reconstruction: A Review of the Literature.

BACKGROUND: Tissue expansion generates new tissue that can be used in post-burn reconstruction. Expanders are placed through small incisions, requiring difficult and sometimes blind dissection to prepare an adequate pocket. Recently, the use of endoscopy to assist in expander placement has been described, which may improve intraoperative visualization and allow for a smaller incision. In this review, we summarize the existing literature of endoscopic tissue expander (TE) placement in post-burn reconstruction and highlight areas for future research. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to conduct this review. The following databases were queried for the initial search of relevant articles: PubMed, Embase, Scopus, Cochrane, and Web of Science. The data was assessed qualitatively due to the heterogeneity in reporting between the studies. RESULTS: Our literature query yielded 1,023 studies. Sixteen manuscripts underwent full-text review, and seven met inclusion criteria. All studies demonstrated that the endoscopic approach led to successful tissue expansion. Four articles performed a comparative analysis between the open and endoscopic approach, all of which found a significant reduction in complications like seroma, hematoma formation, and device exposure with endoscopic TE implantation. Two studies demonstrated that the use of endoscopy significantly reduced operative time and length of stay. CONCLUSION: Endoscopy is a safe and effective tool in tissue expansion for post-burn reconstruction. Further prospective research should include evaluating the cost-benefit of this approach and long-term outcomes for patients who have undergone endoscopic-assisted tissue expander placement.

The Forgotten Flap: The Pedicled Trapezius Flap's Utility in Pediatric Head and Neck Reconstruction-A Systematic Review.

BACKGROUND: When free tissue transfer is precluded or undesired, the pedicled trapezius flap is a viable alternative for adults requiring complex head and neck (H&N) defect reconstruction. However, the application of this flap in pediatric reconstruction is underexplored. This systematic review aimed to describe the use of the pedicled trapezius flap and investigate its efficacy in pediatric H&N reconstruction. METHODS: A systematic review was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles describing the trapezius flap for H&N reconstruction in pediatric patients were included. Patient demographics, surgical indications, wound characteristics, flap characteristics, complications, and functional outcomes were abstracted. RESULTS: A systematic review identified 22 articles for inclusion. Studies mainly consisted of case reports (n = 11) and case series (n = 8). In total, 67 pedicled trapezius flaps were successfully performed for H&N reconstruction in 63 patients. The most common surgical indications included burn scar contractures (n = 46, 73.0%) and chronic wounds secondary to H&N masses (n = 9, 14.3%). Defects were most commonly located in the neck (n = 28, 41.8%). The mean flap area and arc of rotation were 326.4 ± 241.7 cm2 and 157.6 ± 33.2 degrees, respectively. Most flaps were myocutaneous (n = 48, 71.6%) and based on the dorsal scapular artery (n = 32, 47.8%). Complications occurred in 10 (14.9%) flaps. The flap's survival rate was 100% (n = 67). No instances of functional donor site morbidity were reported. The mean follow-up was 2.2 ± 1.8 years. CONCLUSION: This systematic review demonstrated the reliability of the pedicled trapezius flap in pediatric H&N reconstruction, with a low complication rate, no reports of functional donor site morbidity, and a 100% flap survival rate. The flap's substantial surface area, bulk, and arc of rotation contribute to its efficacy in covering soft tissue defects ranging from the proximal neck to the vertex of the scalp. The pedicled trapezius flap is a viable option for pediatric H&N reconstruction.

Navigating Scar Care: An Evaluation of Scar Treatment Patient Education Materials.

While patient education materials (PEMs) across various specialties have been reported as being too difficult to read, the quality and understandability of PEMs related to scar management have not been assessed. In this study, we report the breadth of scar management interventions and readability of online PEMs authored by academic societies and university hospitals. Websites of academic medical societies and university hospitals with scar revision PEMs were assessed for relevance. PEM readability was assessed via Flesch Reading Ease, Flesch-Kincaid Grade Level, and Gunning-Fox Index scores. Understandability and actionability were evaluated using the Patient Education Material Assessment Tool (PEMAT). A total of 26 scar revision PEMs met the inclusion criteria. The most commonly mentioned scar management interventions were scar revision surgery (73%) and laser scar revision (70%), with minimal emphasis on non-invasive methods like scar massage or sun protection. Readability analysis yielded a mean Flesch reading level of 8.8. Overall PEMAT understandability of online scar treatment PEMs was moderate, with a median of 76.0% (IQR 71.5 - 80.5%). PEMs from all specialties and institution types were lacking in actionability, with median actionability of 40.8% (IQR 38.1-60.0%). Online scar revision PEMs included a wide breadth of scar management interventions, however the least costly interventions of sun protection and scar massage were not commonly included. PEMs for scar management could be improved by simplifying language, including visual aids, and including checklists or specific steps patients can take to take action on scar management interventions.

Analyzing Burn-Related Content on Social Media Platforms: A Study of Creator Types, Content Focus, and Engagement Metrics.

Social media offers a readily available, cost-effective way for medical experts to disseminate knowledge and shape public health outcomes but also allows for the spread of misinformation. This study aims to analyze burn-related material on social media by creator, content type, and engagement. Facebook, TikTok, and X (formerly Twitter) were queried with the following search terms: "burn," "burn injury," "burn recovery," and "burn treatment." Identified accounts were then manually screened for relevance. Year of creation and engagement metrics were collected. Accounts were categorized by content and creator type. Data was reported using descriptive statistics and visualized graphically to explore trends. Our search yielded 434 profiles, 234 of which met inclusion criteria. TikTok had the most engagement at a median of 43,500 followers per account, with 38.3% of accounts focusing on individual experiences of burn survivors primarily on personal accounts (48.3%). In contrast, content on Facebook was related to promotion of medical services (36.9%), where the most represented creator type was medical centers (33.6%). Nonprofits made up 40.4% of accounts on Twitter/X and more than a third of the content focused on patient advocacy, support, or burn prevention (36.5%). Important topics like burn education, prevention, and social support are lacking on major social media platforms. Engagement from burn care organizations and burn experts on social media is necessary. The findings of this study may guide advocates in the burn community on where and how to disseminate information in social media.

Neuropathic pain in burn patients - A common problem with little literature: A systematic review.

BACKGROUND: The prevalence of neuropathic pain (NP) in burn patients is reported in the literature to be as high as 80%1. Given the complexity of NP in burn patients and the wide range of treatments available, a systematic review of the literature is warranted to summarize our current understanding of management and treatment of NP in this population. METHODS: This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The following databases were queried to identify relevant articles: PubMed, Cochrane, Embase, Scopus, Ovid, and Web of Science. The main outcome measures were incidence and management of NP. Secondary outcomes included risk factors for NP. RESULTS: Included articles presented findings from 11 different countries, capturing outcomes for 4366 patients. Risk factors for neuropathic pain in burn patients were identified, including older age, alcohol and substance abuse, current daily smoking, greater % total body surface area burns (TBSA), and longer hospitalizations. Pharmacologic treatments included gabapentin/pregabalin (n = 7), ascorbic acid (n = 1), and lidocaine (n = 1). Overall, the studies showed varied results regarding the efficacy of pharmacological treatments. While certain studies demonstrated gabapentanoids to be effective in reducing neuropathic symptoms, others found conflicting results. With regards to non-pharmacologic treatments, electroconvulsive therapy (n = 1), electropuncture (n = 1), nerve release/reconstruction (n = 2), and somatosensory feedback rehabilitation (n = 1) were used and demonstrated promise in reducing pain intensity and improving functionality. CONCLUSIONS: Despite NP afflicting the majority of burn patients long after their injury, this systematic review demonstrates insufficient evidence on the pathophysiology, outcomes, and risk factors in NP, as well as the efficacy of various therapies. Future prospective and randomized studies evaluating the etiology of these factors can substantially improve our treatment strategies. This can allow for the development of well-delineated and evidence-based protocols in NP management in hopes of improving quality of life and both psychological and physical function in burn patients.

Surgical Management of Diabetic Foot Burns is Associated with Poor Outcomes: A Systematic Review and Meta-Analysis.

There is no consensus for the optimal management of diabetic foot burn injuries. Here, we systematically identify studies reporting on diabetic foot burns and evaluate outcomes among patients managed operatively versus non-operatively. PubMed, Embase, and Web of Science were searched. Screening was performed by independent reviewers. Primary research studies with English full texts published between 1980 to 2023 that discussed outcomes of foot burns in adults with diabetes were included and critically appraised using validated tools. Results are presented using descriptive statistics of aggregated data. The search yielded 2,402 non-duplicate papers, of which 35 met inclusion criteria. Nine papers were included for meta-analysis, including seven retrospective comparative analyses, one cross-sectional study, and one retrospective chart review. There were 1798 diabetic foot burn patients. Mean age was 58.2 years (SD 4.12) and 73.1% (n = 1,314) were male. A total of 15.7% (n = 283) of patients were surgically managed, including debridement (3.7%, n = 66), grafting (8.2%, n = 147), flap (0.2%, n = 3), and primary amputation (7.1%, n = 127). Secondary amputation rate, defined as amputation following initial surgery, was 4.9%, (n = 14). The overall amputation rate was 7.8% (n = 141). Other complications included infection (4.0%, n = 72), osteomyelitis (1.9%, n = 34), and graft failure (8.2%, n = 12). One study reported functional status at last visit. Diabetic foot burns are highly morbid. The surgical management of these complex injuries is high risk, as amputation results in poorer quality of life and functional outcomes.

Lessons Learned from a Single Institution's Eight Years of Experience with Early Cleft Lip Repair.

Background and Objectives: The traditional approach in managing wide cleft lip deformities involves presurgical nasoalveolar molding (NAM) therapy followed by surgical cleft lip repair between three and six months of age. This institution has implemented an early cleft lip repair (ECLR) protocol where infants undergo primary cleft lip repair between two and five weeks of age without NAM. This study aims to present this institution's ECLR repair protocol over the past eight years from 188 consecutive patients with unilateral or bilateral CL/P deformity. Materials and Methods: Retrospective review was conducted at Children's Hospital Los Angeles evaluating patients who underwent ECLR before three months of age and were classified as American Society of Anesthesiologists (ASA) class I or II from 2015-2022. Anthropometric analysis was performed, and pre- and postoperative photographs were evaluated to assess nasal and lip symmetry. Results: The average age at cleft lip repair after correcting for gestational age was 1.0 ± 0.5 months. Mean operative and anesthetic times were 120.3 ± 33.0 min and 189.4 ± 35.4, respectively. Only 2.1% (4/188) of patients had postoperative complications. Lip revision rates were 11.4% (20/175) and 15.4% (2/13) for unilateral and bilateral repairs, respectively, most of which were minor in severity (16/22, 72.7%). Postoperative anthropometric measurements demonstrated significant improvements in nasal and lip symmetry (p < 0.001). Conclusions: This analysis demonstrates the safety and efficacy of ECLR in correcting all unilateral cleft lip and nasal deformities of patients who were ASA classes I or II. At this institution, ECLR has minimized the need for NAM, which is now reserved for patients with bilateral cleft lip, late presentation, or comorbidities that preclude them from early repair. ECLR serves as a valuable option for patients with a wide range of cleft severity while reducing the burden of care.

Scanning ion conductance microscopy reveals differential effect of PM2.5 exposure on A549 lung epithelial and SH-SY5Y neuroblastoma cell membranes.

Numerous studies have linked a wide range of diseases including respiratory illnesses to harmful particulate matter (PM) emissions indoors and outdoors, such as incense PM and industrial PM. Because of their ability to penetrate the lower respiratory tract and the circulatory system, fine particles with diameters of 2.5 µm or less (PM2.5) are believed to be more hazardous than larger PMs. Despite the enormous number of studies focusing on the intracellular processes associated with PM2.5 exposure, there have been limited reports studying the biophysical properties of cell membranes, such as nanoscale morphological changes induced by PM2.5. Our study assesses the membrane topographical and structural effects of PM2.5 from incense PM2.5 exposure in real time on A549 lung carcinoma epithelial cells and SH-SY5Y neuroblastoma cells that had been fixed to preclude adaptive cell responses. The size distribution and mechanical properties of the PM2.5 sample were characterized with atomic force microscopy (AFM). Nanoscale morphological monitoring of the cell membranes utilizing scanning ion conductance microscopy (SICM) indicated statistically significant increasing membrane roughness at A549 cells at half an hour of exposure and visible damage at 4 h of exposure. In contrast, no significant increase in roughness was observed on SH-SY5Y cells after half an hour of PM2.5 exposure, although continued exposure to PM2.5 for up to 4 h affected an expansion of lesions already present before exposure commenced. These findings suggest that A549 cell membranes are more susceptible to structural damage by PM2.5 compared to SH-SY5Y cell membranes, corroborating more enhanced susceptibility of airway epithelial cells to exposure to PM2.5 than neuronal cells.
