Pediatric Patients with Post-Burn Amputations Report Worse Long-Term Physical Function but Not Self-Appearance: A Burn Model System Study.

Some severe burn injuries may warrant amputation; however, the physical and functional adjustments resulting from post-burn amputation can have long-term consequences. This study investigates longitudinal functional and psychosocial outcomes among pediatric burn amputees. Pediatric participants enrolled in the Burn Model System national longitudinal, multicenter database between 2015-2023 with post-burn amputations were included. Participants with amputations were matched using nearest-neighbor matching to those without amputations based on burn location, age, and % total burn surface area burn size. Primary outcomes were the PROMIS Pediatric-25 Profile v2.0 Physical Function and the Children Burn Outcomes Questionnaire: appearance sub-score, both measured at 6-, 12- and 24 months post-burn. In this study, 17 participants had amputations and 17 did not (matched participants). Pairwise analyses at each timepoint found those with amputations reported significantly lower physical function scores at 24 months post-burn (54.9 ±11.6 vs. 66 ±5, p=0.013). No significant differences were found in appearance scores. This study suggests that pediatric burn amputees may potentially face greater physical impairment long-term, highlighting an important area of research that deserves further attention.

A Comparison of Postoperative Outcomes Based on Muscle versus Fasciocutaneous Flaps in Scalp Reconstruction: A Systematic Review and Meta-Analysis.

INTRODUCTION: Scalp reconstruction in plastic and reconstructive surgery often necessitates the transfer of soft tissue flaps to restore form and function. The critical decision lies in choosing between muscle-containing (MC) and fasciocutaneous (FC) flaps for scalp reconstruction, and while both variants have their merits, flap composition remains a subject of ongoing debate. This scientific discussion aims to explore this contentious issue through a comprehensive meta-analysis, shedding light on the rationale behind the choice of these flaps and the potential impact on clinical outcomes. METHODS: A comprehensive systematic review was conducted following PRISMA-P guidelines, encompassing six prominent databases up to the year 2023. Data were collected from studies assessing outcomes of MC and FC flaps for scalp reconstruction. Quality evaluation was performed using ASPS criteria and the ROBINS-I tool. Statistical analysis included descriptive statistics, meta-analysis, sensitivity analysis, and assessment of bias using STATA software. RESULTS: The meta-analysis included 28 non-randomized studies, totaling 594 flaps (380 MC, 214 FC). MC flaps were significantly larger than FC flaps. There were no significant differences in flap loss, flap necrosis, or wound dehiscence between the two flap types. However, the incidence of venous congestion was significantly higher in FC flaps. Sensitivity analysis confirmed the robustness of results, and publication bias assessment showed no significant evidence of bias. CONCLUSIONS: While both MC and FC flaps offer viable options for scalp reconstruction, the choice should be tailored to individual patient characteristics and defect size. FC flaps may provide advantages such as shorter operative times and reduced morbidity, whereas MC flaps could be preferred for addressing larger defects. Future research should focus on prospective studies and strategies to mitigate venous congestion in FC flaps, enhancing their safety and efficacy in scalp reconstruction.

A comparison of postoperative outcomes based on recipient vessels in scalp free flap reconstruction: A systematic review and meta-analysis.

PURPOSE: The superficial temporal artery (STA) and facial artery (FA) are two commonly used recipient vessels when performing free tissue transfer to the head and neck. This meta-analysis compares the impact of recipient vessel location on free flap outcomes in scalp reconstruction. METHODS: A systematic review was conducted following PRISMA-P guidelines using six databases. Studies reporting free tissue transfer using the STA or FA as a recipient vessel for reconstructing scalp defects were included. Outcomes of interest included flap loss, partial flap necrosis, wound dehiscence, venous thrombosis, and infection rates. Quality evaluation was performed using ASPS criteria and the ROBINS-I tool. RESULTS: Of 3270 identified articles, 12 were included for final analysis. In total, 125 free flaps were identified (75 STA, 50 FA). Pooled analysis demonstrated an overall flap survival rate of 98.4% (STA 98.7% vs. FA 98.0%; p = .782). The mean defect size was significantly greater for flaps using the STA compared with the FA (223.7 ± 119.4 cm2 vs. 157.1 ± 96.5 cm2, p = .001). The FA group had a higher incidence of wound dehiscence than the STA group (14.0% vs. 1.3%, p = .005). However, meta-analysis demonstrated no significant difference in rates of wound dehiscence, flap loss, partial flap necrosis, venous congestion, or postoperative infection between groups. CONCLUSION: This is the first systematic review and meta-analysis to assess recipient vessel selection in scalp reconstruction. Our results do not support a single vessel as the superior choice in scalp reconstruction. Rather, these findings suggest that the decision between using the STA or FA is multifaceted, requiring a flexible approach that considers the individual characteristics of each case. Further research is needed to explore additional factors influencing recipient vessel selection, including defect location, radiation therapy, and prior head and neck surgery.

The Efficacy of Onion Extract on the Prevention or Treatment of Scars: A Systemic Review.

Scars are common and debilitating outcomes of burn injury, with no current consensus regarding the gold standard in scar management. Non-invasive interventions such as silicone gels are popular adjuvant treatments due to ease of application. Onion extract (OE) has been proposed as a potential scar treatment modality due to its anti-microbial and anti-inflammatory properties. A systematic search of the literature was conducted using PubMed, Scopus, and Cochrane for articles published between January 2000 and December 2021. Inclusion criteria were studies: (a) involved OE gel or OE treatment, and (b) those assessing scar prevention or treatment outcomes. Patient and physician reported scar outcomes after treatment and adverse effects were recorded. A total of 21 articles were included in the final review. Five studies found statistically significant improvements in overall scores and individual VSS components in the OE treatment group compared to the silicone groups. Several studies found combined treatment of OE with other topical treatment modalities such as triamcinolone or silicone gel produced significant improvements in scar symptoms. In this review, reported adverse effects were minimal, often consisting of self-resolving pruritus, irritation, and erythema. This review supports OE's potential utility in scar prevention and treatment. Most studies reported minimal adverse events with OE application and significant benefits in specific scar characteristics. Further research is needed to investigate scar outcomes after treatment with OE with larger sample sizes and a follow up period greater than a year.

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

There is no consensus on 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 vs nonoperatively. PubMed, Embase, and Web of Science were searched. Screening was performed by independent reviewers. Primary research studies with English full texts published between 1980 and 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 2402 nonduplicate papers, of which 35 met the inclusion criteria. Nine papers were included for meta-analysis, including 7 retrospective comparative analyses, 1 cross-sectional study, and 1 retrospective chart review. There were 1798 diabetic foot burn patients. The mean age was 58.2 years (SD 4.12), and 73.1% (n = 1314) 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). The 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 the 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.

Assessing Scar Outcomes Using Objective Scar Measurement Tools: An Adjunct to Validated Scar Evaluation Scales.

INTRO: The assessment of scar outcomes is important to both patient care and research focused on understanding the results of medical and surgical interventions. The Vancouver Scar Scale and Patient and Observer Scar Assessment Scale are validated and simple instruments to assess scars. However, these subjective scales have shortcomings. The VSS fails to capture patient perception and has indeterminate validity and reliability. The POSAS captures patient perception, but the observer scale has been shown to have moderate amounts of inter-rater variability. Studies highlighting the ability of objective scar assessment tools to produce reliable and reproducible results are needed. In this study, we aimed to validate the use of the Fibrometer ®, Elastimeter ®, and SkinColorCatch ® as an objective adjunct in the assessment of hypertrophic scar and keloid outcomes. METHODS: This was a prospective single-center study which assessed patient scars using the Vancouver Scar Scale, the Patient and Observer Scar Assessment scale, and the aforementioned objective study tools. Correlations between the different methods of scar assessment were measured. RESULTS: The Fibrometer ® and SkinColorCatch ® showed significant correlations with the VSS total and the Observer POSAS total. The Elastimeter ® showed significant correlations with both the Patient and Observer POSAS totals. Unexpected correlations between Elastimeter ® measurements and the vascularity/pigmentation of scars indicate that scoring of these categories may be influenced by how severe the scar looks to the observer subjectively, further necessitating the need for reliable objective scar assessment tools. CONCLUSION: These results highlight the ability of these devices to assess scars and demonstrate their potential in serving as an important adjunct to previously validated scar assessment scales.

Evaluation of YouTube As A Source For Graves' Disease Information: Is High-Quality Guideline-Based Information Available?

Objective: To understand the quality of informational Graves' disease (GD) videos on YouTube for treatment decision-making quality and inclusion of American Thyroid Association (ATA) treatment guidelines. Study Design: Cross-sectional cohort. Setting: Informational YouTube videos with subject matter "Graves' Disease treatment." Method: The top 50 videos based on our query were assessed using the DISCERN instrument. This validated algorithm discretely rates treatment-related information from excellent (≥4.5) to very poor (<1.9). Videos were also screened for ATA guideline inclusion. Descriptive statistics were used for cohort characterization. Univariate and multivariate linear regressions characterized factors associated with DISCERN scores. Significance was set at P < .05. Results: The videos featured 57,513.43 views (SD = 162,579.25), 1054.70 likes (SD = 2329.77), and 168.80 comments (SD = 292.97). Most were patient education (52%) or patient experience (24%). A minority (40%) were made by thyroid specialists (endocrinologists, endocrine surgeons, or otolaryngologists). Under half did not mention all 3 treatment modalities (44%), and 54% did not mention any ATA recommendations. Overall, videos displayed poor reliability (mean = 2.26, SD = 0.67), treatment information quality (mean = 2.29, SD = 0.75), and overall video quality (mean = 2.47, SD = 1.07). Physician videos were associated with lower likes, views, and comments (P < .001) but higher DISCERN reliability (P = .015) and overall score (P = .019). Longer videos (P = .015), patient accounts (P = .013), and patient experience (P = .002) were associated with lower scores. Conclusion: The most available GD treatment content on YouTube varies significantly in the quality of medical information. This may contribute to suboptimal disease understanding, especially for patients highly engaged with online health information sources.

Laser-Assisted Drug Delivery in the Treatment of Hypertrophic Scars and Keloids: A Systematic Review.

Hypertrophic scars and keloids are the results of an exaggerated healing process and are often associated with significant patient morbidity. Fractional ablative lasers create microchannels in the skin and penetrate into the substance of the scar, inducing a normal healing response in zones of created damage. Focal delivery of scar-modulating agents into the scar through these microchannels-a process termed laser-assisted drug delivery (LADD)-is a promising and developing treatment modality. In this systematic review, we aim to critically examine the evidence of LADD in the treatment of hypertrophic scars and keloids. The evidence suggests that LADD improves outcomes in hypertrophic scars and keloids. LADD is a more effective treatment modality than the topical application of agents in hypertrophic scars and equally effective as the intralesional injection of agents in keloids. There were few reports of adverse events. Evidence supports the use of LADD as an adjunct to non-surgical measures or a treatment modality to be used before more invasive measures such as surgical excision. However, the quality of evidence supporting this conclusion is inconsistent and lacks power. Additional studies are required to optimize dosages, laser settings, and agent choices for the treatment of these lesions.

A Comparison of Otolaryngology Residency Applicants Over Time and to Other Surgical Applicants.

Objective: Understand how otolaryngology residency applicant characteristics have changed over time and compare them to those of other surgical subspecialties. Study Design: Retrospective analysis of academic, extracurricular, and application data in the Texas Seeking Transparency in Application to Residency databases. Setting: Applicants to otolaryngology, neurological surgery, ophthalmology, plastic surgery, urology, and orthopedic surgery applicants from 2019 to 2023. Methods: Kruskal-Wallis, Wilcoxon rank sum, Fischer's exact, and Mann-Whitney U tests were used to compare temporal, match-based, and subspecialty differences in applicant characteristics. Results: Across 4 match cycles and 541 otolaryngology applicants, significant differences were found in the average number of honored clerkships per applicant (P = 0.044), the percentage of matched applicants (P = 0.017), and the average number of research experiences (P < 0.001), peer-revied publications (P = 0.002), applied programs (P < 0.001), and interviews received (P = 0.041). Relative to their unmatched counterparts, matched applicants frequently received more interviews, belonged to higher academic quartiles, and were more likely to belong to academic honor societies (all P < 0.05). Matched applicants exhibited significant differences in the number of research experiences (P = 0.002), peer-reviewed publications (P = 0.004), and applied programs across cycles (P < 0.001). Relative to applicants from other surgical subspecialties, otolaryngology applicants exhibited high amounts of extracurricular involvement, were on par in terms of research output, and received a low proportion of interviews despite applying to a high number of programs. Conclusion: Matching into otolaryngology has become increasingly competitive and is as competitive as peer surgical subspecialties. Strong academic performance, judicious program signaling, increased research involvement, and holistic factors like letters of recommendation may help applicants successfully match.

Social Distancing or Socially Dividing? A Greater Proportion of Vulnerable Patients Admitted to a Metropolitan Burn Center During the COVID-19 Pandemic.

Due to stay-at-home mandates and social distancing, we hypothesized the coronavirus disease 2019 global pandemic altered the epidemiology of burn injuries that presented to a single-institution, metropolitan burn center. A retrospective review of adult and pediatric patients admitted to the center during a 3-year period: 3/20/19-3/19/20 (pre-pandemic year), 3/20/20-3/19/21 (pandemic year 1), and 3/20/21-3/19/22 (pandemic year 2). Variables included patient demographics, burn injury, and hospitalization characteristics. A greater proportion of males compared to females were admitted during the pre-pandemic year with a significant increase in this difference during pandemic year 1 (P < .05). There was a significant increase in the proportion of undomiciled patients admitted between the pre-pandemic year and pandemic year 2 (P < .01). There were significant increases in the proportion of admitted patients who were uninsured, had a history of mental illness and/or substance abuse between pandemic years 1 and 2 (P < .001, P < .05, P < .01) and between the pre-pandemic year and pandemic year 2 (P < .001, P < .01, P < .001). There were significant differences in deepest burn depth and burn etiology between individual years. The proportion of patients with burns treated purely non-operatively significantly increased during pandemic year 1 (P < .05). Greater changes in the demographics of patients with burns admitted after the onset of the pandemic were reported compared to the characteristics and management of their burn injuries. Overall, this study demonstrated that a greater proportion of vulnerable patients were admitted during the pandemic, providing a better understanding of existing health disparities and the differential impact of the pandemic on lower socioeconomic populations.

Minority pediatric burn survivors undergo more burn operations: A single center's five-year experience.

Burn injuries remain a significant source of trauma in the United States and disproportionately affect racial and ethnic minorities. Although disparities are well documented in adults, less is known regarding those in pediatric populations. To address this gap in literature, we aim to better characterize burn injuries, inpatient treatments, and post-discharge outcomes in minority pediatric burn patients. We hypothesize minority patients undergo more surgery and re-admissions than non-minority patients for burn care. This is a single institution retrospective chart review of pediatric patient admissions with burn injuries from July 1st, 2016 to July 1st, 2021. Demographics, details of injury, inpatient surgical and non-surgical care, and post-discharge outcomes were collected. Patients identifying as Hispanic/Latino, Black, and Asian were coded as minority patients. Univariate analysis was utilized. A total of 332 patients with average age of 4.9 years (SD: 4.4) and average total burn surface area (TBSA) of 8.5% (SD: 10.0) were collected. Minority patients were significantly more likely to experience accidental burn injury (p < 0.01), inhalational injury (p < 0.01), surgical management (p < 0.01), and to undergo skin graft (p < 0.01) than White patients. Minority patients were significantly more likely to undergo laser treatment after discharge (p < 0.01) than White patients. Our study shows minority pediatric patients are at risk for non-intentional burn injuries that undergo surgical management such as skin grafting and longitudinal reconstructive procedures including laser therapy more often. Short-term goals should include facilitating improved physical and psychosocial outcomes in this often-underserved patient population.

Grill-Related Burn Injuries: A Matched Cohort Study.

Barbequing can result in devastating burn injuries with unsafe practices. This study aims to characterize the demographics, injury characteristics, and outcomes of grill-related burns and identify ways of burn prevention. A retrospective review of patients admitted to a single-institution, metropolitan burn center from January 1, 2017, to July 1, 2023. Data included demographics, burn injury characteristics, and outcomes. Each Grill Cohort patient was matched to 3 nongrill controls by mBaux score and burn location. Of 2355 patients, 69 (2.9%) met Grill Cohort inclusion criteria. The Grill Cohort had 55 (79.7%) males and an average age of 41.7 ± 17.5 years old. In the Grill Cohort, 25 (36.2%) patients had positive blood alcohol, 8 (11.6%) tested positive for amphetamines, and 5 (7.2%) for cocaine at the time of admission. A total of 61 (88.4%) Grill Cohort burns involved the upper extremity, 43 (62.3%) the head/neck, 34 (49.3%) the lower extremity, and 30 (43.5%) the trunk. Compared with the Control Cohort, the Grill Cohort had smaller proportions of patients who were undomiciled (P < .01) or had a history of mental illness (P < .001). Grill-related burns had a greater proportion of flash/flame burns (P < .001). This study suggests that middle-aged, domiciled males without psychiatric comorbidities are more likely to make preventable grilling errors resulting in burn injuries. Prevention strategies targeting this demographic group should emphasize the risks of grilling while intoxicated, proper handling of propane tanks and lighter fluid, and the use of flash/flame-resistant gear protecting the upper extremities and head/neck.

Blood glucose control in the burn intensive care unit: A narrative review of literature.

Burn survivors undergoing complex glycemic derangements in the acute period after burn are at significantly increased risk of worse outcomes. Although most critical care investigations recommend intensive glycemic control to prevent morbidity and mortality, conflicting recommendations exist. To date, no literature review has studied outcomes associated with intensive glucose control in the burn intensive care unit (ICU) population. This review addresses this gap to improve practice guidelines and support further research regarding glycemic control. This is a narrative review of literature utilizing PubMed for articles published at any time. Inclusion criteria were English studies describing glucose management in ICU adult burn patients. Studies involving pediatric patients, non-human subjects, care non-ICU care, case reports, editorials, and position pieces were excluded. Our literature search identified 2154 articles. Full text review of 61 articles identified eight meeting inclusion criteria. Two studies reported mortality benefit of intensive glucose control ( mg/dL) compared to controls ( mg/dL), while two studies showed no mortality differences. Three studies reported reduced infectious complications such as pneumonia, urinary tract infection, sepsis, and bacteremia. A majority of the studies (6/8) reported higher risk for hypoglycemia with tight glucose control, but few reported instances of adverse sequela associated with hypoglycemia. Intensive glucose control may provide benefit to burn patients, but complications associated with hypoglycemia must be considered. This review recommends an individualized patient-centered approach factoring comorbidities, burn injury characteristics, and risk factors when determining whether to employ intensive glucose control.

Cancel cancer: The immunotherapeutic potential of CD200/CD200R blockade.

Immune checkpoint molecules function to inhibit and regulate immune response pathways to prevent hyperactive immune activity from damaging healthy tissues. In cancer patients, targeting these key molecules may serve as a valuable therapeutic mechanism to bolster immune function and restore the body's natural defenses against tumors. CD200, an immune checkpoint molecule, is a surface glycoprotein that is widely but not ubiquitously expressed throughout the body. By interacting with its inhibitory receptor CD200R, CD200 suppresses immune cell activity within the tumor microenvironment, creating conditions that foster tumor growth. Targeting the CD200/CD200R pathway, either through the use of monoclonal antibodies or peptide inhibitors, has shown to be effective in boosting anti-tumor immune activity. This review will explore CD200 and the protein's expression and role within the tumor microenvironment, blood endothelial cells, and lymph nodes. This paper will also discuss the advantages and challenges of current strategies used to target CD200 and briefly summarize relevant preclinical/clinical studies investigating the immunotherapeutic efficacy of CD200/CD200R blockade.
