The Use of the Symani Surgical System® in Emergency Hand Trauma Care.

Background: The use of robotic systems for microsurgery has gained popularity in recent years. Despite its drawbacks, such as increased learning time and lack of haptic feedback, robot-assisted microsurgery is beneficial for emergency care due to its reduced risk of tremor and fatigue. The Symani Surgical System® is 1 example of this advanced technology. The device offers a range of possibilities in the field of microsurgery by combining precision and dexterity, revolutionizing microsurgical procedures. This article explores the applications of the Symani in microsurgical procedures in emergency hand trauma care, highlighting its advantages and limitations. Material and Methods: We present the results of 62 anastomoses of blood vessels under .8 mm diameter after hand trauma. 31 anastomoses were conducted using the Symani Surgical System®, and the other 31 were done as a control group in hand-sewn technique. Study Sample: The patient characteristics, including sex, age, and risk factors, were matched. Results: We found no significant differences in the anastomosis surgery length when performed with the Symani (arterial 17.3 ± 1.9 min; venous 11.5 ± 1.3 min) vs the hand-sewn technique (arterial 16.1 ± 1.4 min; venous 10.2 ± 1.8 min). Additionally, the learning curve consistently decreased over time, with the 10th surgery taking 30% (arterial) less time. Conclusion: Our study indicates that robot-assisted microsurgery can help surgeons maintain a relaxed and focused state while producing results comparable to hand-sutured procedures in emergency care.

Gynecomastia Surgery in 4996 Male Patients Over 14 Years: A Retrospective Analysis of Surgical Trends, Predictive Risk Factors, and Short-Term Outcomes.

BACKGROUND: The high prevalence of benign male breast tissue enlargement (gynecomastia) has resulted in a marked increase of gynecomastia cases. While about one third of male adults experience some form of gynecomastia, gynecomastia surgery (GS) outcome research is limited to small study populations and single-center/-surgeon databases. In this study, we aimed to access the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to identify preoperative risk factors for complications and investigate postoperative outcomes of GS. METHODS: In this retrospective study, we queried the ACS-NSQIP database from 2008 to 2021 to identify male adult patients who underwent GS. Postoperative outcomes involved the occurrence of any, surgical and medical complications, as well as reoperation, readmission, and mortality within a 30-day postoperative time period. Univariable and multivariable assessment were performed to identify risk factors for complications while adjusting for possible confounders. RESULTS: The study included 4,996 GS patients with a mean age of 33.7 ± 15 years and BMI of 28.2 ± 5.1 kg/m2. White patients constituted 54% (n = 2713) of the cohort, and 27% (n = 1346) were obese. Except for 2020, there was a steady increase in GS cases over the study period. Outpatient surgeries were most common at 95% (n = 4730), while general surgeons performed the majority of GS (n = 3580; 72%). Postoperatively, 91% (n = 4538) of patients were discharged home; 4.4% (n = 222) experienced any complications. Multivariable analysis identified inpatient setting (p < 0.001), BMI (p = 0.023), prior sepsis (p = 0.018), and bleeding disorders (p = 0.047) as independent risk factors for complications. CONCLUSION: In this study, we analyzed 4996 male adult GS patients from the ACS-NSQIP database, revealing an increased caseload and significant general surgeon involvement. Risk factors like bleeding disorders, inpatient status, and prior sepsis were linked to postoperative complications, while BMI was crucial for predicting adverse events. Overall, our findings may aid in enhancing patient care through advanced preoperative screening and closer perioperative management.

Thinking like a Lawyer-Human Rights and Their Association with the Plastic Surgeon of Today.

Plastic surgeons are trained to perform a wide repertoire of surgeries-ranging from standard local procedures to highly specialized operations. Therefore, plastic surgeons treat a plethora of clinical presentations and address multiple patient needs. Their daily workflow is increasingly entwined with legal topics. The concrete legal interpretation falls within the remit of legal experts. However, by understanding the legal basics of selected surgical procedures, plastic surgeons may generate synergies in patient care and clinical practice. The legal situation is to be elucidated based on the German Basic Law (GBL) and the European Convention on Human Rights (ECHR).

Short-term efficacy and adverse effects of collagenase clostridium histolyticum injections, percutaneous needle fasciotomy and limited fasciectomy in the treatment of Dupuytren's contracture: a network meta-analysis of randomized controlled trials.

AIMS: Dupuytren's contracture (DC) is a chronic debilitating fibroproliferative disorder. Common treatment options include collagenase clostridium histolyticum injections (CI), percutaneous needle fasciotomy (NF) and limited fasciectomy (LF). Superiority of one specific treatment remains controversial. This study aims to assess the short-term efficacy and safety of CI, NF, and LF for the treatment of DC. METHODS: We included randomized controlled trials of CI compared with placebo, NF and LF for patients with DC. PubMed, Embase and the Cochrane Library were searched from inception to August 2021. Contracture reduction rates in treated joints (within 0-5° of full extension within 30 days), relative reduction in total passive extension deficit (TPED), occurrence of one or more adverse events and number of treatment-related adverse events per patient were the outcomes of interest. The Cochrane risk-of-bias tool was employed for quality assessment of the studies. A network meta-analysis was performed using MetaXL. RESULTS: Nine studies met our inclusion criteria (n = 903). Overall, risk bias was mixed and mostly low. Short term TPED reduction achieved with LF was superior compared to CI and NF. Although CI achieved greater TPED reduction compared to NF, it was associated with the highest risk of overall adverse effects. The analyzed data was limited to a maximum three-year follow-up period and therefore insufficient for long-term outcome evaluation. CONCLUSIONS: In DC, LF may be able to provide patients with severe disease, superior flexion contracture release postoperatively. CI is a valid treatment alternative to NF, however the higher risk of overall adverse effects must be considered. The quality-of-evidence is limited due to short-term follow-up periods and a lack of standardized definitions of complications and adverse events.

Superficial Temporal Recipient Vessels for Craniofacial Microvascular Free-Flaps.

The selection of recipient vessels for microvascular free-flaps is critical in craniofacial reconstruction. Especially the suitability of the superficial temporal vessels is questioned conflictingly in the literature. The aim of this study was to share our experience with microvascular craniofacial free-flap reconstruction and to evaluate a set of factors that are related to the recipient vessels and to determine how these factors influence flap survival. We conducted a retrospective analysis of 39 free-flaps for craniofacial reconstruction that were performed from 2006 until 2020 and evaluated the indication for microvascular reconstruction, recipient vessels, various factors related to the recipient vessels and complications. The most utilized recipient artery was the facial artery, selected in 20 patients followed by the superficial temporal artery selected in 12 patients. The most commonly used recipient vein was the facial vein used in 16 patients, followed by the superficial temporal vein selected in 10 patients and the external jugular vein in 6 patients. Total flap necrosis occurred in one patient. There was no statistically significant association between the selected recipient vessels and patient comorbidities, major and minor complications, revision of anastomosis or flap loss. The results of our study have demonstrated that the superficial temporal artery and vein show similar results when used for face and scalp reconstruction. Considering their technical and aesthetic advantages they may be the first choice recipient vessels in established free-flap treatment algorithms for craniofacial reconstruction.

Complications and Disasters After Minimally Invasive Tissue Augmentation with Different Types of Fillers: A Retrospective Analysis.

BACKGROUND: The interest in youthful appearance and rejuvenating procedures is unbroken in our society. Besides surgical procedures, permanent fillers are utilized. The incorrect and unprofessional use of these substances, auto-injections in particular, have devastating results for patients and are challenging for the plastic surgeon. The aim of this retrospective study was to delineate the differences between permanent and non-permanent filler complications and appropriate treatment options. METHODS: We conducted a retrospective study and researched the hospital information system in the time period from 2001 to 2020. Patients with unprofessional use of permanent fillers, auto-injections and injections of unformulated substances were determined. Age, gender, localization, complications, length of hospital stay, comorbidities, histopathological workups and surgical salvage procedures were noted. Descriptive statistics were calculated. RESULTS: Seventeen patients were identified from 2001 till 2020. In four cases, auto-injections by the patients were the cause, whereas in the other patients the injections were performed by medical staff. Ages range from 18 to 57 years. Fourteen patients were female and three were male. The injected substances could be recognized as synthol, silicone, vaseline, fat tissue, hyaluronic acid as well as non-medical substances. Surgical procedures were necessary in eleven cases. One patient died because of the underlying diseases. CONCLUSION: Our results indicate different sequels of filler materials injected in an unprofessional way, possible complications, conservative and surgical techniques to resolve these rare complications. We suggest a staged therapy adjusted to the clinical symptoms. Milder symptoms can be handled conservatively, whereas severe infections, skin breakdowns or persistent granuloma are justifying indications for surgical treatment.

Botulinum Toxin Versus Placebo: A Meta-Analysis of Treatment and Quality-of-life Outcomes for Hyperhidrosis.

AIMS: This study aims at assessing the treatment effect, disease severity and quality-of-life outcomes of botulinum toxin (BTX) injections for focal hyperhidrosis. METHODS: We included randomized controlled trials of BTX injections compared with placebo for patients with primary or secondary focal hyperhidrosis. PubMed, Embase and the Cochrane Library were searched to August 2020. Gravimetric sweat rate reduction, disease severity measured by Hyperhidrosis Disease Severity Scale and quality-of-life assessment measured by Dermatology Life Quality Index were the outcomes of interest. Cochrane risk-of-bias tools were employed for quality assessment of given randomized controlled trials. RESULTS: Eight studies met our inclusion criteria (n=937). Overall, risk bias was mixed and mostly moderate. BTX injections showed reduced risk in comparison with placebo for the gravimetric quantitative sweat reduction of > 50 % from baseline (risk difference: 0.63, 95% CI 0.51 to 0.74). Additionally, improvements were seen for disease severity and quality-of-life assessments evaluated by Hyperhidrosis Disease Severity Score reduction of ≥ 2 points (risk difference: 0.56, 95% CI 0.42 to 0.69) and mean change in Dermatology Life Quality Index (mean difference: - 5.55, 95% CI - 7.11 to - 3.98). The acquired data were insufficient to assess for long-term outcomes and limited to an eight-week follow-up period. CONCLUSIONS: In focal axillary hyperhidrosis, BTX significantly reduces sweat production and yields superior outcomes in assessments of disease severity and quality-of-life. However, the quality-of-evidence is overall moderate and included studies account for short-term trial periods only. Further studies assessing BTX in comparison with first-line treatments for hyperhidrosis are warranted.

Suprachiasmatic function in a circadian period mutant: Duper alters light-induced activation of vasoactive intestinal peptide cells and PERIOD1 immunostaining.

Mammalian circadian rhythms are entrained by photic stimuli that are relayed by retinal projections to the core of the suprachiasmatic nucleus (SCN). Neuronal activation, as demonstrated by expression of the immediate early gene c-fos, leads to transcription of the core clock gene per1. The duper mutation in hamsters shortens circadian period and amplifies light-induced phase shifts. We performed two experiments to compare the number of c-FOS immunoreactive (ir) and PER1-ir cells, and the intensity of staining, in the SCN of wild-type (WT) and duper hamsters at various intervals after presentation of a 15-min light pulse in the early subjective night. Light-induced c-FOS-ir within 1 hr in the dorsocaudal SCN of duper, but not WT hamsters. In cells that express vasoactive intestinal peptide (VIP), which plays a critical role in synchronization of SCN cellular oscillators, light-induced c-FOS-ir was greater in duper than WT hamsters. After the light pulse, PER1-ir cells were found in more medial portions of the SCN than FOS-ir, and appeared with a longer latency and over a longer time course, in VIP cells of duper than wild-type hamsters. Our results indicate that the duper allele alters SCN function in ways that may contribute to changes in free running period and phase resetting.

Subcutaneous mastectomy in female-to-male transsexuals is associated with higher risk of postoperative bleeding complications.

Introduction: Chest contouring or subcutaneous mastectomy (SCM) in female-to-male (FtM) transgender individuals is the primary surgery in the gender reassignment process. Many authors report high rates of postoperative bleeding in these patients and discuss a possible influence of preoperative hormone therapy. However, there is a lack of data on the analysis between different surgical techniques and postoperative bleeding risk. Materials and Methods: In this retrospective study, we included 22 FtM transgender individuals who underwent bilateral SCM using 4 different techniques (44 breasts) between June 2014 and September 2023. Postoperative complications regarding surgical techniques and patient demographics were collected and analyzed. Results: SCM with free nipple grafting was the most commonly used technique (n = 12, 54.5%). The mean operative time was 163.4 ± 49.2 minutes. There were no significant differences in operative time between the surgical techniques (p ≥ 0.20 in all cases). The rate of acute postoperative bleeding was 20.5% (n = 9). Acute postoperative bleeding occurred most frequently in patients who received a semi-circular incision for SCM. There was no significant difference in the rate of acute postoperative bleeding between the different surgical techniques. BMI, breast weight, and duration of surgery were not associated with the rate of acute complications (p > 0.17 in all cases). Conclusions: Less invasive SCM techniques in FtM transgender individuals are associated with higher postoperative bleeding risk.

Quality of life and satisfaction after breast augmentation: A systematic review and meta-analysis of Breast-Q patient-reported outcomes.

BACKGROUND: Breast augmentation ranks among the most popular plastic surgery procedures. Yet, reports on post-operative patient-reported quality of life (QoL) and satisfaction remain conflicting. METHODS: A systematic review was conducted following the PRISMA guidelines. Three databases were searched for eligible studies that reported pre-and/or post-operative Breast-Q™ augmentation scores for patient QoL (psychosocial, sexual, and physical well-being) and/or satisfaction. RESULTS: A total of 39 studies (53 patient cohorts and 18,322 patients) were included in the quantitative synthesis. The pairwise meta-analysis revealed significant improvements in patient-reported psychosocial (MD: +38.10) and sexual well-being (MD: +40.20) as well as satisfaction with breast (MD: +47.88) (all p < 0.00001). Physical well-being improved slightly after breast augmentation (MD: +6.97; p = 0.42). The single-arm meta-analysis yielded comparable results, with Breast-Q™ scores in psychosocial and sexual well-being as well as satisfaction with breast increasing from 37.2, 31.1, and 26.3 to 75.0, 70.6, and 72.7, respectively (all p < 0.00001). Physical well-being improved by 8.1 (75.8 pre-operatively to 83.9 post-operatively; p = 0.17). Subgroup analyses highlighted higher QoL and satisfaction following breast augmentation for purely esthetic purposes and alloplastic mammaplasty. Although patient-reported physical and sexual well-being increased in the long term, psychosocial well-being was the highest in the short term. CONCLUSION: Patient satisfaction with breast, psychosocial, and sexual well-being increased significantly after breast augmentation. In contrast, patient-reported physical well-being yielded ambivalent results, varying by mammaplasty technique and post-operative follow-up time. Plastic surgeons should be sensitized about our findings to refine eligibility criteria and gain a deeper understanding of the patients' perceived surgical experience.

Bone-targeting engineered small extracellular vesicles carrying anti-miR-6359-CGGGAGC prevent valproic acid-induced bone loss.

The clinical role and underlying mechanisms of valproic acid (VPA) on bone homeostasis remain controversial. Herein, we confirmed that VPA treatment was associated with decreased bone mass and bone mineral density (BMD) in both patients and mice. This effect was attributed to VPA-induced elevation in osteoclast formation and activity. Through RNA-sequencing, we observed a significant rise in precursor miR-6359 expression in VPA-treated osteoclast precursors in vitro, and further, a marked upregulation of mature miR-6359 (miR-6359) in vivo was demonstrated using quantitative real-time PCR (qRT-PCR) and miR-6359 fluorescent in situ hybridization (miR-6359-FISH). Specifically, the miR-6359 was predominantly increased in osteoclast precursors and macrophages but not in neutrophils, T lymphocytes, monocytes and bone marrow-derived mesenchymal stem cells (BMSCs) following VPA stimulation, which influenced osteoclast differentiation and bone-resorptive activity. Additionally, VPA-induced miR-6359 enrichment in osteoclast precursors enhanced reactive oxygen species (ROS) production by silencing the SIRT3 protein expression, followed by activation of the MAPK signaling pathway, which enhanced osteoclast formation and activity, thereby accelerating bone loss. Currently, there are no medications that can effectively treat VPA-induced bone loss. Therefore, we constructed engineered small extracellular vesicles (E-sEVs) targeting osteoclast precursors in bone and naturally carrying anti-miR-6359 by introducing of EXOmotif (CGGGAGC) in the 3'-end of the anti-miR-6359 sequence. We confirmed that the E-sEVs exhibited decent bone/osteoclast precursor targeting and exerted protective therapeutic effects on VPA-induced bone loss, but not on ovariectomy (OVX) and glucocorticoid-induced osteoporotic models, deepening our understanding of the underlying mechanism and treatment strategies for VPA-induced bone loss.

Personalized Treatment Decisions for Traumatic Proximal Finger Amputations: A Retrospective Cohort Study.

Ray and proximal phalanx amputations present valid surgical options for the management of severe traumatic finger injuries. However, among these procedures, the superior one for optimal functionality and quality of life for patients still remains unknown. This retrospective cohort study compares the postoperative effects of each amputation type to provide objective evidence and to create a paradigm for clinical decision-making. A total of forty patients who had received either ray or proximal phalanx-level amputations reported on their functional outcomes using a combination of questionnaires and clinical testing. We found a decreased overall DASH score following ray amputation. Particularly, Part A and Part C of the DASH questionnaire were consistently lower compared with amputation at the proximal phalanx. Pain measurements in the affected hand were also significantly decreased during work and at rest in ray amputation patients, and they reported decreased cold sensitivity. Range of motion and grip strength were lower in ray amputations, which is an important preoperative consideration. We found no significant differences in reported health condition, evaluated according to the EQ-5D-5L, and blood circulation in the affected hand. We present an algorithm for clinical decision-making based on patients' preferences to personalize treatment.

Outcomes following burn injury in intensive care patients with major psychiatric disorders.

AIMS: Patients with psychiatric comorbidity have been shown to experience high rates of burn injury. Burn epidemiology, etiology, and outcomes have been sparsely documented for patients with major psychiatric disorders. The aim of this study was to analyze the epidemiologic characteristics and outcomes in intensive care burn patients with pre-existing and acute major psychiatric disorders . METHODS: A retrospective study was performed including intensive care burn patients admitted between March 2007 and December 2020. Demographic, clinical and epidemiological data were collected and analyzed. Major psychiatric co-morbidities were collected according to ICD-9 and ICD-10 classifications. Patients were stratified according to F-diagnoses. RESULTS: A total of 1325 patients were included. 16.6 % of all patients had one or more major psychiatric disorders- 9.3 % with anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders, 9.2 % with mood (affective) disorders, 3.5 % with schizophrenia and other non-mood psychotic disorders, and 1.8 % with disorders of adult personality and behavior. Patients with major psychiatric disorders presented with significantly higher burn severity, reflected by higher abbreviated burn severity index (ABSI) scores (5.9 vs. 5.3, p < 0.001) and larger total body surface area (TBSA) affected (15.9 vs. 12.5 %, p = 0.002). Burned TBSA ≥ 30 and inhalation injuries were observed more frequently in patients with MDP, however without statistical significance. They also experienced prolonged hospital length-of-stay (LOS) (25.5 vs. 16.3 days, p < 0.001), prolonged intensive care unit LOS (14.8 vs. 7.7 days, p < 0.001), underwent surgical interventions (3.5 vs. 2.3, p < 0.001) and mechanical ventilation more frequently (34.1 % vs. 16.5 %, p = 0.43) and had significantly longer ventilation durations (73.5 vs. 31.2 h, p = 0.002). Mortality rates were lower compared to patients without major psychiatric disorders (5.9 vs. 8.1, p < 0.001). CONCLUSIONS: The prevalence of major psychiatric disorders in burn patients is considerably high. Patients with psychiatric comorbidities were found to have greater burn severity, prolonged total hospital and ICU LOS, underwent surgical interventions and mechanical ventilation more frequently and had prolonged ventilation duration. Our results highlight the importance of identifying burn patients with major psychiatric disorders who may necessitate additional resources and require extensive inpatient psychiatric care and counseling.

Correlation between Bacterial Wound Colonization and Skin-Graft Loss in Burn Patients.

Loss of skin grafts can be a dangerous complication during the early postoperative course of patients with extensive burns. A major risk factor for impaired healing of grafts is local wound infection due to bacterial colonization. Burn wounds are particularly prone to bacterial colonization. In this retrospective cohort study, we analyzed correlations between bacteria isolates from burn wounds and loss of skin grafts after surgical treatment. A cohort of patients with burn wounds who received split-skin grafts for wound coverage was divided into groups with and without loss of skin grafts. Demographics, comorbidities, trauma characteristics and bacterial isolates from wound cultures were reviewed and compared. Bacterial colonization isolated from burn wounds upon hospital admission was found to be a significant predictor of skin-graft loss. Additionally, an Abbreviated Burn Severity Index greater 6 predicted graft loss. When comparing bacterial swab results from admission with isolates from revision surgery after graft loss, causative pathogens were found to have changed.

Blood Vessel Injuries of the Fingers: A Clinical Comparison of One- and Two-Arterial Blood Supply.

Traumatic finger injuries are very common in emergency medicine. When patients present with finger injuries, there is often damage to the vascular nerve bundles, which requires subsequent reconstruction. It is unknown if repairing a unilaterally injured artery affects patients' recovery in a well-perfused finger. This retrospective cohort study compares the clinical outcomes of 11 patients with one-vessel supply (mean age 48.3 years; 7 males, 4 females) to 14 patients with two-vessel supply (mean age 44.5 years; 8 males, 6 females). The patient outcomes were assessed using patient questionnaires (Disabilities of Arm, Shoulder, and Hand (DASH), European Quality of Life 5 Dimensions 5 Level Version (EQ-5D-5L), and EuroQol visual analog scale (EQ-VAS)) and a clinical examination of hand function and imaging of circulatory efficiency. No significant changes were observed in the DASH, EQ-5D-5L, and EQ-VAS questionnaires. Clinical evaluation of hand function, measured by cold sensitivity, two-point discrimination, pain numerical analog scale, and grip strength also revealed no significant differences between cohorts. Blood flow measurements using thermal imaging revealed no effects on circulation in the affected digit. Collectively, the study finds reconstruction is not absolutely necessary when there is one intact digital artery as it is sufficient for healing and functional outcomes. We recommend finger artery reconstruction when both digital arteries are injured or if an immediate tension-free suture is possible.

Factor XIII: More than just a fibrin stabilizer for the burn patient? A matched-pair analysis.

Background: Acquired factor XIII deficiency is an underestimated risk in patients with large surface burns, which potentially exposes these patients to prolonged bleeding and delayed wound healing if undetected. Methods: A retrospective matched-pair analysis of the burn registry of the Department of Plastic, Aesthetic, Hand, and Reconstructive Surgery of Hannover Medical School was performed from 2018 to 2023. Results: A total of 18 patients were included. Acquired factor XIII deficiency was not statistically significant correlated with age, sex, or body mass index. Patients who developed acquired factor XIII deficiency had a significantly longer hospital stay (72.8 days) compared with those in the matched group (46.4 days), although burn depths, total body surface area, and Abbreviated Burn Severity Index were not statistically correlated with factor XIII deficiency. Conclusions: Little is known about acquired factor XIII deficiency in patients with burns. Factor XIII supplementation may improve hemostasis, wound healing, and general outcome while reducing the patient's exposure to blood products.

Attempted Suicide by Burning: A Cross-sectional Analysis at a Regional Burn Center in Germany.

Attempted suicide by self-immolation or burning constitutes an uncommon form of attempted suicide in high income countries, presenting substantial challenges to burn units. The aim of this study was to analyze the epidemiologic characteristics and outcomes in intensive care burn patients treated for attempted suicide by burning. For this purpose, we examined intensive care burn patients admitted to a single major burn unit between March 2007 and December 2020. Demographic, clinical, epidemiological, and mortality data were collected and analyzed. Major psychiatric comorbidities were evaluated according to ICD-9 and ICD-10 classifications. A total of 1325 intensive care unit burn patients were included. Suicide by burning was attempted in 45 cases (3.4%). Attempted suicide victims presented with significantly higher burn severity, reflected by higher abbreviated burn severity index scores, and larger TBSA affected. Burned TBSA ≥30% and inhalation injuries were observed more frequently in suicidal patients. These patients also experienced prolonged hospital and intensive care unit length of stay, required surgical interventions and mechanical ventilation more frequently, and had significantly longer periods on ventilation, causing an overall higher mortality rate (24.4%). Psychiatric comorbidities were present in 75.6% of patients who attempted suicide. Despite the low prevalence, burn severity and mortality are considerably high in patients who attempted suicide by burning, presenting a significant challenge for healthcare providers. The majority of patients had a history of psychiatric disorder, highlighting the importance of identifying patients at high-risk who may profit from increased psychiatric intervention.

Epidemiology and outcome analysis of 1359 intensive care burn patients: A 14-year retrospective study in a major burn center.

AIMS: Globally, burn-related morbidity and mortality still remain high. In order to identify regional high-risk populations and to suggest appropriate prevention measure allocation, we aimed at analyzing epidemiological characteristics, etiology and outcomes of our 14-year experience with an intensive care unit (ICU) burn patient population. METHODS: A retrospective observational study was conducted including patients treated between March 2007 and December 2020 in our intensive care burn unit. Demographic, clinical and epidemiological data were collected and analyzed. RESULTS: A total of 1359 patients were included. 68% of the subjects were males and the largest age group affected entailed 45-64-year-old adults (34%). Regarding etiology, flame and contact burns were the most common in all age groups. Mean affected total body surface area (TBSA) was 13 ± 14.5% in all subjects. Most of the burns occurred domestically or during recreational activities. Mean hospital stay was 17.77 ± 19.7 days. The average mortality was 7.7%. The mortality rate showed an overall decreasing trend whilst burn severity remained consistent from 2007 to 2020. CONCLUSIONS: Despite consistent burn severity presentations of annual ICU admissions, burn injury mortality showed a decreasing trend, which was in part attributed to substantial progress in burn care and treatment and improved burn prevention awareness. Statistically significant age and gender differences could be detected with regard to burn etiology and seasonality, as well as outcomes, which highlight the importance of individualized primary prevention programs.

In-hospital Mortality Following Suicidal Burns: A Propensity Score-Matched Analysis.

We carried out a retrospective single-center study and analyzed all patients who have been admitted to our intensive care burn unit following suicide attempt and accidental burns within 14 years. Clinical and demographic parameters were collected and evaluated. Propensity score matching was performed in order to minimize the confounding effect of the parameters age, sex, total body surface area (TBSA), and the presence of full-thickness burns and inhalation injury. 45 burn patients following attempted suicide by burning and 1266 patients following accidental burn injury were admitted. Patients with suicidal burn injuries were significantly younger and showed significantly higher burn severity, reflected by larger TBSA affected, higher incidence of full-thickness burns and inhalation injury. They also experienced increased hospital length of stay (LOS) and longer ventilation durations. Their in-hospital mortality was significantly higher. Following propensity score matching in 42 case pairs, no differences were detected with regard to in-hospital mortality, hospital LOS, duration of mechanical ventilation, and frequency of surgical interventions. Attempted suicide by burning is associated with overall worse outcomes and higher mortality rates. Following propensity score matching, significant differences in outcomes were no longer detectable. Given the comparable survival probability compared to accidentally burned patients, life-sustaining treatment should not be withheld in burn patients following suicide attempt.

The modified 5-item frailty index as a predictor of complications in burn patients.

The modified 5-item frailty index (mFI-5), as a measure of frailty and biological age, has been shown to be a reliable predictor of complications and mortality in a variety of surgical specialties. However, its role in burn care remains to be fully elucidated. We, therefore, correlated frailty with in-hospital mortality and complications after burn injury. The medical charts of all burn patients admitted between 2007 and 2020 who had ≥ 10 % of their total body surface area affected were retrospectively reviewed. Data on clinical, demographic, and outcome parameters were collected and evaluated, and mFI-5 was calculated on the basis of the data obtained. Univariate and multivariate regression analyses were used to investigate the association between mFI-5 and medical complications and in-hospital mortality. A total of 617 burn patients were included in this study. Increasing mFI-5 scores were significantly associated with increased in-hospital mortality (p < 0.0001), myocardial infarction (p = 0.03), sepsis (p = 0.005), urinary tract infections (p = 0.006), and perioperative blood transfusions (p = 0.0004). They were also associated with an increase in the length of hospital stay and the number of surgical procedures, albeit without statistical significance. An mFI-5 score of ≥ 2 was a significant predictor of sepsis (odds ratio [OR] = 2.08; 95% confidence interval [CI]: 1.03 to 3.95; p = 0.04), urinary tract infection (OR = 2.82; 95% CI: 1.47 to 5.19; p = 0.002), and perioperative blood transfusions (OR = 2.61; 95% CI: 1.61 to 4.25; p = 0.0001). Multivariate logistic regression analysis revealed that an mFI-5 score of ≥ 2 was not an independent risk factor for in-hospital mortality (OR = 1.44; 95% CI: 0.61 to 3.37; p = 0.40). mFI-5 is a significant risk factor for only a few select complications in the burn population. It is not a reliable predictor of in-hospital mortality. Therefore, its utility as a risk stratification tool in the burn unit may be limited.
