RESUMO
BACKGROUND: Despite the growing prevalence of burn survivors, a gap persists in our understanding of the correlation between acute burn trauma and the long-term impact on psychosocial health. This study set out to investigate the prevalence of long-term pain and symptoms of anxiety and depression in survivors of extensive burns, comparing this to the general population, and identify injury and demographic-related factors predisposing individuals to psychosocial compromise. METHODS: RE-ENERGIZE was an international, double-blinded, randomized-controlled trial that enrolled 1200 patients with partial- or full-thickness burns that required surgical treatment. For the post hoc analysis, we excluded participants who did not complete the Short Form Health Survey (SF-36) questionnaire. Normative data were taken from the 2021 National Health Interview Survey dataset. Propensity score matching was performed using the nearest-neighbor 1-to-1 method, and the two cohorts were compared in terms of chronic pain, and symptoms of anxiety and depression. A multivariable analysis was performed on the burns cohort to identify factors predicting post-discharge pain and symptoms of anxiety and depression. RESULTS: A total of 600 burn patients and 26,666 general population adults were included in this study. Following propensity score matching, both groups comprised 478 participants each, who were predominately male, white, overweight and between 20 and 60 years old. Compared to the general population, burn patients were significantly more likely to report the presence of moderate and a lot of pain (p = 0.002). Symptoms of anxiety were significantly higher in the burn population in two of four levels (most of the time; some of the time; p < 0.0001 for both). Responders in the burn population were significantly less likely to report the absence of depressive symptoms (p < 0.0001). Burn patients were also significantly more likely to report that their mental health affects their social life. TBSA, history of depression, and female sex were identified as independently associated factors for pain, anxiety, and depressive symptoms. The presence of chronic pain and anxiety symptoms independently predicted for symptoms of depression. CONCLUSIONS: Analyzing the largest multicenter cohort of patients with extensive burns, we find that burn injury is associated with chronic pain, and symptoms of anxiety and depression. In addition, TBSA-burned and history of depression directly correlate with the prevalence of chronic pain, and symptoms of anxiety and depression. Finally, pain, and symptoms of anxiety and depression are interrelated and may have interactive effects on the process of recovery following burn injury. Burn patients would, therefore, benefit from a multidisciplinary team approach with early mobilization of pain and mental health experts, in order to promptly prevent the development of psychosocial challenges and their consequences.

Oncoplastic breast surgery (OBS) arose to decrease the deformity following breast conserving surgery (BCS) for breast cancer. In this meta-analysis (MA), we pool Breast-Q™ questionnaire data to compare quality of life (QOL) in breast cancer patients who received BCS alone or in combination with Level I or II oncoplastic breast surgery (BCS+OBS). All relevant databases were searched following the PRISMA and QUOROM guidelines. All prospective or retrospective studies with a BCS or BCS+OBS cohort that reported QOL as assessed with the Breast-Q™ questionnaire were eligible. Fifty-five studies (75 distinct patient cohorts; 11,186 patients) were included in the MA, with 12 studies reporting both pre- and postoperative values and eligible for a pairwise MA. The pairwise MA showed a significant postoperative improvement in the overall satisfaction with the breast (MD +8.0%, p=0.003) and in the psychosocial well-being (MD +9.2%, 3.5-14.8, p=0.001) of the entire cohort (BCS and BCS+OBS). A subgroup MA of proportions highlighted a superiority of BCS+OBS to BCS in terms of overall satisfaction with the breast (72.0%, 68.0-76.1, versus 62.9%, 58.3-67.5; p=0.02) and psychosocial well-being (78.9%, 71.5-86.4, versus 73.3%, 67.3-76.5, p=0.0001). A leave-one-out sensitivity analysis confirmed the results of the pairwise MA and the MA of proportions. Oncoplastic breast surgery effectively improves QoL based on the patient-reported outcomes assessed using the Breast-Q™ questionnaire. The improvements were associated with acceptable complication rates, further supporting the use of BCS followed by OBS where mastectomy would otherwise be necessary.
RESUMO
BACKGROUND: The BREAST-Q questionnaire reduction module is an established tool for outcomes after reduction mammoplasty. OBJECTIVES: This systematic review and meta-analysis assess key parameters affecting pre- and postoperative scores, with specific foci on patient characteristics and tissue resection weights. METHODS: This study was conducted per PRISMA guidelines. PUBMED (National Institutes of Health; Bethesda, MD), Google Scholar (Google; Mountain View, CA), and Web of Science (Clarivate Analytics; Philadelphia, PA) were searched. All studies published before August 1, 2021, were assessed for eligibility by 2 independent reviewers. Inclusion criteria were prospective or retrospective studies in 6 languages that reported quality of life after reduction mammoplasty employing the BREAST-Q questionnaire reduction module. Quality of included studies was assessed employing the Newcastle-Ottawa-Scale. Analysis was performed per Cochrane Collaboration and the Quality of Reporting of Meta-analyses guidelines. RESULTS: A total of 28 papers were included in the systematic review, 13 for preoperative meta-analysis, and 17 for postoperative meta-analysis. Postoperative scores in all 3 quality of life domains (psychosocial, physical, and sexual well-being) and satisfaction with breasts increased significantly after reduction mammoplasty compared with preoperative scores. Satisfaction with breasts showed the greatest improvement, from 22.9 to 73.0. Preoperative scores were lower than normative data, with improvement to comparable scores as the healthy population postoperatively. Improvements in BREAST-Q scores did not correlate with patient comorbidities, complication rates, or amount of breast tissue resected. CONCLUSIONS: Reduction mammoplasty provides marked improvement in BREAST-Q patient-reported quality of life as well established in literature. However, these improvements do not correlate with tissue resection weights, warranting further inquiry of insurance-defined resection requirements.

BACKGROUND: As the cost of healthcare rises, it is imperative to assess value delivered to patients and impact on the economic viability of institutions. We aimed to characterize plastic surgery operative time management and identified areas for efficiency improvement. METHODS: Procedures from a US academic plastic surgery division from September 2017 to August 2018 were reviewed. Times were categorized into preparation (patient in room to incision), procedure (incision to closure), exit (closure to patient exiting room), and turnover (patient out of room to next patient in room). Median and interquartile ranges were calculated. Procedures were classified by relative value units (RVUs) for comparison of procedure complexities and resources. Components were plotted against RVUs; r2 values were calculated. RESULTS: We analyzed 522 cases; 69 were excluded for missing data, primary surgeon not a plastic surgeon, emergent cases, or burn procedures; a total of 453 cases were analyzed. Median and interquartile range (in minutes) for preparation was (34, 18 minutes; 23% of total), procedure (53, 75 minutes; 36% of total), exit (30, 27 minutes; 20% of total), and turnover (30, 26 minutes; 20% of total). Normalized to RVUs, preparation demonstrated the most variability (r2 = 0.19), followed by exit (r2 = 0.38), and procedure (r2 = 0.57). Average work RVUs per month was 678.1 ± 158.7. Average work RVUs per OR hour was 7.2. CONCLUSIONS: The largest component with greatest variability was preparation for surgery in the OR. Improved efficiency by decreasing variability increases the value of healthcare delivered to patients and OR throughput.

BACKGROUND AND OBJECTIVES: The transverse musculocutaneous gracilis (TMG) flap has gained popularity for breast reconstruction. However, the literature regarding its donor site morbidity is heterogeneous. This systematic review sought to clarify the evidence on donor site morbidity. METHODS: A systematic literature search was conducted. We included all articles reporting on donor-site morbidity of the TMG flap for breast reconstruction. The results were analyzed in R and its extension meta. A generalized linear mixed model was used to combine proportions and their 95% confidence intervals (CIs) in a random-effects meta-analysis. RESULTS: Nineteen articles provided an overall sample of 843 TMG flaps. The total flap loss was low at 2% (95% CI, 1%-3%). All patients were normal weight (pooled body mass index 22.75, 95% CI, 21.88-23.63). The incidence of wound dehiscence (8%, 95% CI, 4%-16%), seroma (4%, 95% CI, 2%-7%), hematoma (2%, 95% CI, 1%-4%) and infection (0%-5%) on the TMG donor site was low. Functional impairments included sensory disturbance (0%-74%), motoric deficits (0%-50%), and changes in the genital region (0%-24%), all of which were modest. CONCLUSIONS: This review confirms the safety and low donor site morbidity of the TMG flap in normal-weight patients, which is comparable to that of other popular free flaps in breast reconstruction.

OBJECTIVE: Stevens-Johnson syndrome (SJS) and its more severe counterpart, toxic epidermal necrolysis (TEN), are skin hypersensitivity reactions defined by epidermal blistering and necrosis. The exact pathophysiology of SJS/TEN is yet to be deciphered, but a number of risk factors have been identified including adverse drug reactions. The diagnosis of SJS/TEN is made on a clinical basis, and treatment consists of supportive care and occasionally immunosuppressants, such as cyclosporin, high-dose intravenous immunoglobulins and/or corticosteroids. Mortality rates can reach 20-25% in adults but are reduced with early intervention. To identify optimal treatment regimens, to better understand the patient cohort affected, and to help identify key risk factors for mortality, we report our experience with the treatment and management of SJS/TEN patients. METHODS: A retrospective review of consecutive patients with SJS and/or TEN admitted to a single burns centre in Germany, between 2008 and 2018, was conducted. The primary outcomes of demographics, clinical course, treatment and patient-reported outcomes were recorded and compared with a control group of patients with burns without a diagnosis of SJS/TEN. RESULTS: A total of 23 patients with SJS/TEN met the inclusion criteria: 17 (74%) with TEN; four (17%) with SJS/TEN overlap; and two (9%) with SJS. Of the patients, 14 (61%) were female and nine (39%) were male. Patient age ranged from 32-78 years (mean: 52 years). A matched cohort of 23 patients with burns served as the control group. All patients received standard of care with a multidisciplinary team. Compared with the control group, SJS/TEN patients had higher mortality rates (n=6, 26% versus n=8, 35%, respectively). The average age of death was 69 years in SJS/TEN patients versus 63 years in control group patients. Age and SCORTEN scores were significant predictors of mortality. CONCLUSIONS: SJS and TEN are rare but extreme reactions of the skin and mucosa, associated with high disease mortality rates. This 10-year single-centre retrospective review contributes to the bank of information for reviews evaluating the management of SJS/TEN patients.

OBJECTIVE: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare and severe skin and mucosal reactions that are associated with high mortality. Despite the severity, an evidence-based treatment protocol for SJS/TEN is still lacking. METHOD: In this systematic review and meta-analysis, the PubMed database was searched using the following terms: [Stevens-Johnson syndrome] OR [toxic epidermal necrolysis] AND [therapy] OR [treatment] over a 20-year period (1999-2019) in the German and English language. All clinical studies reporting on the treatment of SJS/TEN were included, and epidemiological and diagnostic aspects of treatment were analysed. A meta-analysis was conducted on all comparative clinical studies that met the inclusion criteria. RESULTS: A total of 88 studies met the inclusion criteria, reporting outcomes in 2647 patients. Treatment was either supportive or used systemic corticosteroid, intravenous immunoglobulin, plasmapheresis, cyclosporine, thalidomide or cyclophosphamide therapy. The meta-analysis included 16 (18%) studies, reporting outcomes in 976 (37%) patients. Systemic glucocorticoids showed a survival benefit for SJS/TEN patients in all analyses compared with other forms of treatment. Cyclosporine treatment also showed promising results, despite being used in a small cohort of patients. No beneficial effects on mortality could be demonstrated for intravenous immunoglobulins. CONCLUSION: Glucocorticoids and cyclosporine may be tentatively recommended as the most promising immunomodulatory therapies for SJS/TEN, but these results should be investigated in future prospective controlled trials.

Hair is a defining feature of mammals and has critical functions, including protection, production of sebum, apocrine sweat and pheromones, social and sexual interactions, thermoregulation, and provision of stem cells for skin homeostasis, regeneration, and repair. The hair follicle (HF) is considered a "mini-organ," consisting of intricate and well-organized structures which originate from HF stem and progenitor cells. Dermal papilla cells are the main components of the mesenchymal compartments in the hair bulb and are instrumental in generating signals to regulate the behavior of neighboring epithelial cells during the hair cycle. Mesenchymal-epithelial interactions within the dermal papilla niche drive HF embryonic development as well as the postnatal hair growth and regeneration cycle. This review summarizes the current understanding of HF development, repair, and regeneration, with special focus on cell signaling pathways governing these processes. In particular, we discuss emerging paradigms of molecular signaling governing the dermal papilla-epithelial cellular interactions during hair growth and maintenance and the recent progress made towards tissue engineering of human hair follicles.

BACKGROUND: Surgical learning curves reflect the trainee's rate of progress in gaining skills and competence for new procedures. Complex interventions such as free tissue transfers, with various linked skills and competences, transferred to one procedure are likely to have steep learning curves. This work aimed to report influence of learning curves on outcomes such as success rate, operative time, and complication rates in plastic surgery procedures. METHODS: The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A systematic database literature search (PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trails) was performed. Articles were included when reporting effects of learning curves on outcomes in plastic surgery procedures. RESULTS: Twenty-nine articles focusing on learning curves in plastic surgery procedures were included. Studies reported on non-free flap breast reconstruction, mastectomy, and free flap reconstruction in general and for breast reconstruction and did not allow for pooling of the data because of heterogeneity. Most common outcomes for measuring improvements were success rate, operation time, and complication rate, which demonstrated improvements in almost all studies. Plateaus were reached in 45 to 100 cases for breast reconstructions and were not reported for other procedures. Only 2 studies did not find associations between surgical experience and clinical outcomes. CONCLUSIONS: There are sparse data on learning curves in plastic surgery. Existing studies draw a heterogeneous picture, but especially free flap breast reconstructions seem to undergo learning curves with improvements in operative time, complication rates, and success rates. However, well-designed studies with clearly defined outcomes and comparison between surgeons of different levels over time should be performed.Systematic review registration: PROSPERO: CRD42018108634.

BACKGROUND: Early reconstruction of burn sequelae of the hand can be challenging owing to high goals for functional and aesthetic outcome. A variety of reconstructive procedures with ascending levels of complexity exists and warrants careful indication. METHODS: In this case series, the main reconstructive techniques for reconstruction of burn defects of the hand are described, illustrated, and discussed: split thickness skin grafting (STSG) with fibrin glue, dermal matrices with STSG, distant random pattern (abdominal bridge) flap, distant pedicled flap (superficial circumflex iliac artery flap), and free microvascular tissue transfer (anterolateral thigh flap). An algorithm for decision making in the reconstructive process is proposed. RESULTS: Split thickness skin grafting provides sufficient coverage for partial thickness defects without exposure of functional structures; fixation with fibrin glue avoids unnecessary stapling. Dermal matrices under STSG provide vascularized granulation tissue on full thickness defects and can be used as salvage procedure on functional structures. Distant random pattern or pedicled flaps provide sufficient coverage of large full thickness defects with exposed functional structures but pose some challenges regarding patient compliance and immobilization. Free tissue transfer allows tailored reconstruction of large full thickness defects with exposed functional structures and can be safely and feasibly performed. Secondary and tertiary procedures are needed with more complex techniques; if applied correctly and consequently, all methods can yield favorable functional and aesthetic outcomes. CONCLUSIONS: Reconstruction of the burned hand may require a broad armamentarium of surgical techniques with different levels of complexity, versatility, and applicability. Excellent results can be achieved with the right procedure for the right patient.

OBJECTIVE: To review the effects of burn injury on nutritional requirements and how this can best be supported in a healthcare setting. METHOD: A literature search for articles discussing nutrition and/or metabolism following burn injury was carried out. PubMed, Embase and Web of Science databases were searched using the key search terms 'nutrition' OR 'metabolism' AND 'burn injury' OR 'burns'. There was no limitation on the year of publication. RESULTS: A total of nine articles met the inclusion criteria, the contents of which are discussed in this manuscript. CONCLUSION: Thermal injury elicits the greatest metabolic response, among all traumatic events, in critically ill patients. In order to ensure burn patients can meet the demands of their increased metabolic rate and energy expenditure, adequate nutritional support is essential. Burn injury results in a unique pathophysiology, involving alterations in endocrine, inflammatory, metabolic and immune pathways and nutritional support needed during the inpatient stay varies depending on burn severity and idiosyncratic patient physiologic parameters.

OBJECTIVE: Self-inflicted burns typically result in extensive injuries requiring intensive care and attention in a specialised burn unit. Burn units should be familiar with the optimal management of self-inflicted burns, including the psychological and psychiatric treatment. This paper describes the experiences of managing these challenging injuries in a German burn centre. METHODS: A retrospective review of patients with self-inflicted burns admitted to the burn centre between 2000 and 2017. Demographics, details of injury, presence of psychiatric disorder, clinical course, operative management and patient outcomes were recorded and compared with a control group without self-inflicted burns. Outcome measures included graft take rate, complications and need for further surgery. RESULTS: There were a total of 2055 burn patient admissions, with 17 cases (0.8%) of self-inflicted burns. The mean age was 36±11 years with an mean percentage total body surface area (%TBSA) burned of 43.5±22.5% which was not significantly different from the control group (p=0.184). Schizophrenia and personality disorder were the most common diagnoses in the self-inflicted burns patients (n=11; 65%). Of these, four had sustained previous self-inflicted burns. Length of hospital stay was significantly longer in the self-inflicted burn group than in the control group (49.0±16.7 days, respectively, p=0.002). CONCLUSION: Attempted suicide by self-inflicted burns represents <1% of burn admissions. This population demonstrates a high incidence of prior psychiatric disorders. Successful treatment includes multidisciplinary management of acute medical, surgical, and psychiatric care.

BACKGROUND: Burns that involve the perineum, buttocks and genitals (PBG) have been associated with more challenging therapeutic needs and worse clinical outcomes. We aimed to investigate whether PBG burns are an independent predictor for mortality, morbidity and complications in a large, heterogenous patient collective and in comparison to patients without PBG burns. PATIENTS AND METHODS: Patients admitted to a level one burn center between August 2014 and July 2022 were included and stratified based on the presence of PBG burns on admission (PBG & control group = CTR). Demographic baseline data, burn aetiology, inhalation trauma (IHT), full-thickness burns (FT), number of operations (NOR), mortality, length of ICU stay (LOS-ICU), length of in-hospital stay (LOHS) and bacteraemia were assessed to compare key clinical characteristics and outcomes between the groups. Multivariate regression analyses and a 1:1 propensity score matching were conducted for key clinical outcomes. RESULTS: A total of 1024 patients were included in the analysis (PBG: n = 227; CTR: n = 797). PBG burns were older (median (IQR) 54 (34-72) vs. 44, (30-61) years, p < 0.0001), more frequently female (35% vs. 23%, p = 0.002) presented with larger total body surface area (TBSA) burns overall (27 (32-39) vs. 10 (13-15) %, p < 0.0001) and sustained FT burns more frequently (69% vs. 26% p < 0.0001). Scald burns were more frequently the cause of PBG burns (45% vs. 15%, p < 0.0001), PBG patients needed twice as many surgical procedures (Mean (SD) 2 (2.84) vs. 1 (1.6), p < 0.0001) as CTR. In multivariate analyses, a significant correlation was identified between length of ICU stay and presence of PBG burns. Following strict cohort matching to account for sex, age, cause of burn, TBSA %, presence of FT burn, inhalation trauma and bacteraemia, PBG burns were an independent predictor for mortality (p = 0.0003). CONCLUSION: PBG burns are at risk for prolonged intensive care, hospitalization and complications during treatment. Furthermore, the presence of PBG burns appears to be a risk factor for mortality, irrespective of patient age, TBSA affected and other relevant covariates.

INTRODUCTION: Extensive full-thickness soft-tissue defects remain a challenge in reconstructive surgery. NovoSorb® Biodegradable Temporising Matrix (BTM) represents a novel dermal substitute and was evaluated in wounds deriving from different aetiologies and to highlight risk factors for poor take rates. METHODS: All patients treated with BTM at our department between March 2020 and October 2022 were included. Differences in univariate and linear regression models identified predictors and risk factors for take rates of BTM and split-thickness skin grafts (STSG). RESULTS: Three hundred patients (mean age 54.2 ± 20.1 years, 66.3% male, 59.7% burns, 19.7% trauma and 20.6% others) were evaluated. Mean take rates of BTM and STSG after BTM delamination were 82.7 ± 25.2% and 86.0 ± 22.6%, respectively. Multiple regression analyses showed that higher body mass index (BMI, OR 0.43, 95% CI 0.86, -0.01, p = 0.44), prior allograft transplantation (OR 15.12, 95% CI 26.98, -3.31, p = 0.041), longer trauma-to-BTM-application intervals (OR 0.01, 95% CI 0.001, -0.001, p = 0.038), positive wound swabs before BTM (OR 7.15, 95% CI 13.50, -0.80, p = 0.028) and peripheral artery disease (OR 10.80, 95% CI 18.63, -2.96, p = 0.007) were associated with poorer BTM take. Higher BMI (OR 0.40, 95% CI 0.76, -0.08, p = 0.026), increasing BTM graft surface areas (OR 0.58, 95% CI -1.00, -0.17, p = 0.005), prior allograft (OR 12.20, 95% CI -21.99, -2.41, p = 0.015) or autograft transplantations (OR 22.42, 95% CI 38.69, -6.14, p = 0.001), tumour as the aetiology of the wound (OR 37.42, 95% CI 57.41, -17.83, p = 0.001), diabetes (OR 6.64, 95% CI 12.80, -0.48, p = 0.035) and impaired kidney function (OR 5.90, 95% CI 10.94, -0.86, p = 0.021) were associated with poorer STSG take after delamination of BTM, whereas higher BTM take rates were associated with better STSG take (OR 0.40, 95% CI 0.31,0.50, p < 0.001). CONCLUSION: Extensive complex wounds of different aetiologies unsuitable for immediate STSG can be successfully reconstructed by means of two-staged BTM application and subsequent skin grafting. Importantly, presence of wound contamination or infection and prior allograft coverage appear to jeopardise good BTM and STSG take.

Objectives: Addressing extensive and deep burn wounds poses considerable challenges for both patients and surgeons. The NovoSorb® Biodegradable Temporizing Matrix (BTM) emerged as a novel dermal substitute and has been subjected to evaluation in large burn wound cases, with a specific focus on identifying risk factors associated with suboptimal take rates. Methods: All patients with burn wounds greater than 10% body surface that underwent BTM treatment between March 2020 and November 2023 were eligible for inclusion. Univariate analyses and linear regression models were employed to discern risk factors and predictors influencing the take rates of both the BTM and split-thickness skin grafts (STSGs). Results: A total of 175 patients (mean age 56.2 ± 19.8 years, 70.3% male) were evaluated. The mean take rates of the BTM and STSGs were 82.0 ± 24.7% and 87.3 ± 19.0%, respectively. There were significant negative correlations between BTM take and the number of surgeries before BTM application (r = -0.19, p = 0.01), %TBSA and STSG take (r = -0.36, p = <0.001) and significant positive correlations between BTM and STSG take (r = 0.41, p ≤ 0.001) in addition to NPWT and STSG take (r = 0.21, p = 0.01). Multivariate regression analyses showed that a larger number of surgeries prior to BTM application (OR -3.41, 95% CI -6.82, -0.03, p = 0.04) was associated with poorer BTM take. Allograft treatment before BTM application (OR -14.7, 95% CI -23.0, -6.43,p = 0.01) and failed treatment with STSG before BTM application (OR -20.8, 95% CI -36.3, -5.23, p ≤ 0.01) were associated with poorer STSG take, whereas higher BTM take rates were associated with overall higher STSG take (OR -0.15, 95% 0.05, 0.26, p = 0.01). The Meek technique was used in 24 patients and showed similar take rates (BTM: 76.3 ± 28.0%, p = 0.22; STSG: 80.7 ± 21.1, p = 0.07). Conclusions: This study summarizes our findings on the application of a BTM in the context of large burn wounds. The results demonstrate that successful treatment can be achieved even in patients with extensive burns, resulting in satisfying take rates for both the BTM and STSG. The data underscore the importance of promptly applying a BTM to debrided wounds and indicate good results when using Meek.
RESUMO
Effective burn surgery is based on two fundamental principles: prompt excision of necrotic tissue and definitive coverage preserving functional dermis and body contour. There is often compromise, either prioritizing the urgency of excision or opting for patient stability and optimal conditions prior to autografting. We propose a surgical concept that addresses this critical treatment gap. In 2022 we implemented a new three-phase protocol, EDM: (Excision phase, E) Immediate excision of the burn wound preserving body contour; (Dermis phase, D) definitive temporization of the wound bed, using Biodegradable Temporizing Matrix (BTM), to prepare it for successful grafting. (Meek phase, M): Upon complete dermal temporization, full autologous coverage in a single micrografting procedure. We performed a retrospective single-center cohort study to characterize the EDM protocol compared to the prior standard of care (>40%TBSA, n=5 in EDM vs. n=10 matched controls). Primary outcomes were total surgeries required, total surgeries to achieve>90% healing, uninterrupted recovery time without surgery, and time on mechanical ventilation. The EDM group required fewer surgeries in total (5 vs. 9.5 ; p=0.01) and to achieve>90% healing (3 vs. 6.5; p=0.001). EDM patients experienced longer uninterrupted recovery (24 vs. 14 days, p=0.001). Additionally, EDM patients spent less time on mechanical ventilation (210 vs. 1136 hours, p=0.005). The EDM protocol could improve surgical efficiency, ultimately having the potential to expedite rehabilitation in severely burned patients. The study underscores the potential of combining fundamentals of burn surgery, with innovative surgical techniques and materials, in order to bridge the gap between excision and grafting.
RESUMO
Background: Prospective randomized trials in severely burned children have shown the positive effects of oxandrolone (OX), beta blockers (BB) and a combination of the two (BBOX) on hypermetabolism, catabolism and hyperinflammation short- and long-term post-burn. Although data on severely burned adults are lacking in comparison, BB, OX and BBOX appear to be commonly employed in this patient population. In this study, we perform a secondary analysis of an international prospective randomized trial dataset to provide descriptive evidence regarding the current utilization patterns and potential treatment effects of OX, BB and BBOX. Methods: The RE-ENERGIZE (RandomizEd Trial of ENtERal Glutamine to minimIZE Thermal Injury, NCT00985205) trial included 1200 adult patients with severe burns. We stratified patients according to their receipt of OX, BB, BBOX or none of these drugs (None) during acute hospitalization. Descriptive statistics describe the details of drug therapy and unadjusted analyses identify predisposing factors for drug use per group. Association between OX, BB and BBOX and clinical outcomes such as time to discharge alive and 6-month mortality were modeled using adjusted multivariable Cox regressions. Results: More than half of all patients in the trial received either OX (n = 138), BB (n = 293) or BBOX (n = 282), as opposed to None (n = 487, 40.6%). Per study site and geographical region, use of OX, BB and BBOX was highly variable. Predisposing factors for the use of OX, BB and BBOX included larger total body surface area (TBSA) burned, higher acute physiology and chronic health evaluation (APACHE) II scores on admission and younger patient age. After adjustment for multiple covariates, the use of OX was associated with a longer time to discharge alive [hazard ratio (HR) 0.62, confidence interval (CI) (0.47-0.82) per 100% increase, p = 0.001]. A higher proportion of days on BB was associated with lower in-hospital-mortality (HR: 0.5, CI 0.28-0.87, p = 0.015) and 6-month mortality (HR: 0.44, CI 0.24-0.82, p = 0.01). Conclusions: The use of OX, BB and BBOX is common within the adult burn patient population, with its use varying considerably across sites worldwide. Our findings found mixed associations between outcomes and the use of BB and OX in adult burn patients, with lower acute and 6-month-mortality with BB and longer times to discharge with OX. Further research into these pharmacological modulators of the pathophysiological response to severe burn injury is indicated.
RESUMO
INTRODUCTION: The epidemiology, care, and outcomes of perineal and genital burns (PG) in high-income countries have been previously described, but an analysis of this topic in LMICs has yet to be performed. We use the World Health Organization's Global Burn Registry to fill this gap. METHODS: The GBR was searched from inception to November 2023 to identify all burn patients, excluding cases from high-income countries. Demographics and mechanism of injury were retrieved. Primary outcomes were length of hospital stay (LOHS), surgical intervention, discharge with physical impairment, and mortality. A multivariate regression analysis was performed controlling for burnt total body surface area (TBSA), age, sex, inhalation injury, mechanism of burn and care center characteristics. RESULTS: Of 9041 patients identified, 1213 (13.4 %) had PG burns with 136 (1.6 %) isolated to the PG region. PG patients had higher TBSA (p < 0.001) and more inhalation injury (p < 0.001). They had better access to rehabilitation and lower access to theater space for burns (p < 0.001). Multivariable analysis showed that PG patients had longer LOHS (p = 0.001), greater mortality (p < 0.001), were less likely to undergo surgery (p = 0.01) or be discharged home with physical impairment (p = 0.03). CONCLUSION: Similarities and differences exist between high- and low/middle-income countries in terms of the patterns of injury, care, and recovery in patients with PG burns. The longer LOHS and higher mortality among PG patients, previously reported in high-income countries, are verified. This highlights the importance of greater vigilance when caring for such patients.

BACKGROUND: Facial burns frequently occur in occupational or household accidents. While dysphagia and dysphonia are known sequelae, little is known about impaired smell and taste after facial burns. METHODS: In a prospective observational controlled study, we evaluated hyposmia via the Sniffin' Stick Test (SnS), hypogeusia via a taste strip test, and dysphonia and dysphagia via validated questionnaires acutely and one-year after burn, respectively. A matched control group consisting of a convenience sample of healthy volunteers underwent the same assessments. RESULTS: Fifty-five facial burn patients (FB) and 55 healthy controls (CTR) were enrolled. Mean burn size was 11 (IQR: 29) % total body surface area (TBSA); CTR and FB were comparable regarding age, sex and smoking status. Acutely, hyposmia was present in 29% of the FB group (CTR: 9%, p = 0.014) and burn patients scored worse on the SnS than CTR (FB: 10; CTR: 11; IQR: 2; p = 0.013). Hyposmia per SnS correlated with subjective self-assessment. Hyposmia and SnS scores improved over time (FB acute: 10.5 IQR: 2; FB one year: 11; IQR: 2; p = 0.042) and returned to normal at one-year post burn in most patients who completed the study (lost to follow-up: 21 patients). Taste strip scores were comparable between FB and CTR, as was the acute prevalence of dysphagia and dysphonia. CONCLUSION: Hyposmia acutely after facial thermal trauma appeared frequently in this study, especially when complicated by inhalation trauma or large TBSA involvement. Of all complete assessments, a fraction of burn patients retained hyposmia after one year while most improved over time to normal. Prevalence of dysphonia, dysphagia and hypogeusia was comparable to healthy controls in this study, perhaps due to overall minor burn severity.

The treatment of geriatric burn patients represents a major challenge in burn care. The objective of this study was to evaluate the efficacy of enzymatic debridement (ED) in geriatric burn patients. Adult patients who received ED for treatment of mixed pattern and full thickness burns (August 2017-October 2022) were included in this study and grouped in the younger (18-65 years) and geriatric (≥65 years) groups. Primary outcome was a necessity of surgery subsequent to ED. Both groups (patient characteristics, surgical and non-surgical treatment) were compared. Multiple logistic and linear regression models were used to identify the effect of age on the outcomes. A total of 169 patients were included (younger group: 135 patients, geriatric group: 34 patients). The burn size as indicated by %TBSA (24.2 ± 20.4% vs. 26.8 ± 17.1%, p = 0.499) was similar in both groups. The ASA (2.5 ± 1.1 vs. 3.4 ± 1.1, p < 0.001) and ABSI scores (6.1 ± 2.8 vs. 8.6 ± 2.3, p < 0.001) were significantly higher in the geriatric group. The %TBSA treated with ED (5.4 ± 5.0% vs. 4.4 ± 4.3%, p = 0.245) were similar in both groups. The necessity of additional surgical interventions (63.0 % vs. 58.8 %, p = 0.763) and the wound size debrided and grafted (2.9 ± 3.5% vs. 2.2 ± 2.1%; p = 0.301) were similar in both groups. Regression models yielded that age did not have an effect on efficacy of ED. We showed that ED is reliable and safe to use in geriatric patients. Age did not have a significant influence on the surgical outcomes of ED. In both groups, the size of the grafted area was reduced and, in many patients, surgery was avoided completely.
