The Role of Burn Centers in the Treatment of Necrotizing Soft-Tissue Infections:A Nationwide Dutch Study

Patients with extensive and complex wounds due to Necrotizing Soft-Tissue Infections (NSTI) may be referred to a burn center. This study describes the characteristics, outcomes, as well as diagnostic challenges of these patients. Patients admitted to three hospitals with a burn center for the treatment of NSTI in a 5-year period were included. Eighty patients (median age 54 years, 60% male) were identified, of whom 30 (38%) were referred by other centers, usually after survival of the initial septic phase. Those referred from other centers, compared to those primarily admitted to the study hospitals, were more likely to have group A streptococcal involvement (62% vs 35%, p = .02), larger wounds (median 7% vs 2% total body surface area, p &lt; .001), and a longer length of stay (median 49 vs 22 days, p &lt; .001). Despite a high incidence of septic shock (50%), the mortality rate was low (12%) for those primarily admitted. Approximately half (53%) of the patients were initially misdiagnosed upon presentation, which was associated with delay to first surgery (16 hours vs 4 hours, p &lt; .001). Those initially misdiagnosed had more (severe) comorbidities, and less frequently reported pain or blue livid discoloration of the skin. This study underlines the burn centers' function as referral centers for extensively affected patients with NSTI. Besides the unique wound and reconstructive expertise, the low mortality rate indicates these centers provide adequate acute care as well. A major remaining challenge remains recognition of the disease upon presentation. Future studies in which factors associated with misdiagnosis are explored are needed.</p

Burn wounds after electrical injury in a bathtub: A case report

Background: Increased smartphone use among minors makes our population more prone to electrical injury. Despite regulations on electrical home safety standards, smartphones and chargers still pose a risk for severe injury among users. Case presentation: We present a case of a patient with low-voltage electrical burns due to smartphone use in a bathtub. The 13-year-old Caucasian patient was using a smartphone plugged into the electrical grid while taking a bath. We report the burns and their treatment. We discuss the likely burn mechanism. Conclusions: Burn wounds after electrical injury due to smartphone use are rare. The presented case shows the danger of smartphone use in bathtubs

Child abuse and neglect in paediatric burns: The majority is caused by neglect and thus preventable

Introduction: It is complex to distinguish negligent burns from inflicted and non-intentional burns, especially since no deliberate action caused the burn. Its recognition is important to create a safe life without (future) burns for our loved-ones who cannot take care of themselves (yet). Our aim was to investigate the incidence and associated characteristics of negligent burns are among children treated at a burn center. Methods: We retrospectively reviewed medical files of all children attending a Dutch burn center with an acute burn between January 2013–December 2015. The conclusion of the Child Abuse and Neglect team (CAN) was used to define inflicted, negligent or non-intentional burns. The remaining cases were reviewed by an expert panel using a standardized protocol. Demographic and social data as well as clinical information about the burn were collected. Results: In total 330 children were included. Negligent burns accounted for 56%, non-intentional for 42% and inflicted for 2% of the burns. Negligent burns were associated with: hot beverages (OR 4.40, 95%CI 2.75–7.05), a younger age (p < 0.001), occurrence at home (OR 4.87 95%CI 2.80–8.45) and were located at the anterior trunk (OR 2.75, 95%CI 1.73–4.35) and neck (OR 1.98, 95%CI 1.12–3.50). Conclusion: This study shows that neglect is a major factor in the occurrence of burns in young children, therefore we conclude that the majority of paediatric burns are preventable. Educational programs creating awareness and focussing on prevention of these burns should be aimed at households, since the majority of negligent as cause of preventable burns occur at home

The impact of necrotizing soft tissue infections on the lives of survivors: a qualitative study

Purpose: Necrotizing soft tissue infections (NSTI) are potentially lethal infections marked by local tissue destruction and systemic sepsis, which require aggressive treatment. Survivors often face a long recovery trajectory. This study was initiated to increase understanding of the long-term impact of NSTI on health related quality of life (HRQoL), and how care may be improved. Methods: Thematic analysis was applied to qualitative data from 25 NSTI-survivors obtained through two focus groups (n = 14) and semi-structured interviews (n = 11). Results: The median age of the participants was 49 years, 14 were female. The median time since diagnosis was 5 years. Initial misdiagnosis was common, causing delay to treatment. Survivors experienced long-term physical consequences (scarring, cognitive impairment, fatigue, sleeping problems, recurrent infections), psychological consequences (traumatic stress symptoms, fear of relapse, adjusting to an altered appearance, sexual issues) and social and relational consequences (changes in social contacts, a lack of understanding). The disease also had a major psychological impact on family members, as well as major financial impact in some. There was a strong desire to reflect on ‘mistakes’ in case of initial misdiagnosis. To improve care, patient and family centered care, smooth transitions after discharge, and the availability of understandable information were deemed important. Conclusion: This study reveals that NSTI have a large impact on physical and psychosocial wellbeing of survivors and their relatives. Except for a few differences (misdiagnosis, fear for re-infection and actual re-infection), the patient experience of patients with NSTI is largely similar to those of burn survivors. Thus, questionnaires to assess HRQoL in burn survivors may be used in future NSTI studies

Detection of bacteria in burn wounds with a novel handheld autofluorescence wound imaging device: A pilot study

Objective: To compare the detection of bacteria in burn wounds between an bacterial fluorescence imaging device MolecuLight i:X, (Canada), and standard microbiological swabs. Methods: Wounds were swabbed three times on one occasion; once with a standard swab, once with a high-fluorescent area swab, indicating a bacterial load >104 colony-forming units (CFU)/ gram and a finally with a non-fluorescent (nF) area swab. Proportion agreement of the microbiological results was calculated and the accuracy of the device to detect relevant bacteria was assessed. Results: A total of 14 patients with 20 wounds participated in the study. Median post-burn day at sampling time was 21 days. Of the 20 wounds, nine had a positive swab result in either of the three swabs, and 11 showed a highfluorescent area. Overall, positive and negative proportion agreement between standard swab and highfluorescent swab sample results were 100%. Sensitivity, specificity, positive and negative predictive values of presence of highfluorescence were 78%, 64%, 64%, and 78%, respectively. For Pseudomonas aeruginosa detection, these results were 100%, 70%, 44% and 100%, respectively. Conclusion: The diagnostic accuracy of the bacterial fluorescence imaging device to detect relevant bacteria in burn wounds was moderate and the reliability was equal to standard swabbing. Further research in larger sample sizes and on the relevance of minimal bacterial load and its potential to help with Pseudomonas aeruginosa management is needed. Declaration of interest: The authors have no conflicts of interests to declare.

The Meek micrograft technique for burns; review on its outcomes: Searching for the superior skin grafting technique

Introduction: Autologous split thickness skin grafting is the standard-of-care for the majority of deep dermal and full thickness burns: Meshed grafting is most commonly used. Patients with extensive burn injuries have limited donor site availability. Meek micrografting is a well-known technique to enable larger expansions. A review was conducted on the outcomes of the Meek micrograft technique. Method: A database search in PubMed, Web of Science, Google Scholar and the Cochrane Library was conducted from the first Meek micrografting report in 1958 until 2021, including terms ‘burns’, ‘micrografting’ and/or ‘Meek’. Original papers reporting outcomes of Meek micrografting were included. Results: 1529 papers were identified and eventually 15 articles were included, the majority classified as poor quality according to Chambers criteria. 310 patients with 56% mean TBSA were described. Weighted averages were calculated for ‘graft take’ 82 ± 7%, ‘time to wound closure’ 53 ± 20 days and ‘length of hospital stay’ 61 ± 31 days. Scar quality was minimally described and often poorly assessed. Limited data were available on outcomes ‘donor site size’, ‘number of operations’, ‘cost effectiveness’ and ‘bacterial load/wound infection rate’. Conclusion: Overall poor study quality and the specific lack of data on scar quality, made it impossible to draw conclusions on the outcomes of Meek micrografting. A randomized controlled trial is required to further investigate the performance of the Meek micrograft technique

Approaches to Surgical Debridement in Necrotizing Soft Tissue Infections: Outcomes of an Animated, Interactive Survey

Background: Necrotizing soft tissue infections (NSTI) affect long-term quality of life in survivors. Different approaches to debridement may influence quality of life. The aim of this study was to assess the current practice of the debridement of NSTI in the Netherlands. Methods: An animated, interactive online survey was distributed among general surgeons and plastic surgeons in the Netherlands. Two NSTI-cases were presented, followed by questions regarding the preferred surgical approach. Case one described a woman with a swollen, red leg, with signs of sepsis and without visible necrosis. Case two described an immunocompromised man with septic shock syndrome and extensive necrosis. Results: In total 232 responses were included (143 general surgeons, 89 plastic surgeons). In case one, 32% chose to preserve all skin, while 17% chose to resect all skin above the affected fascia, including normal-looking skin. In case two, all participants resected necrotic skin, and most (88%) also blue discolored skin. While 32% did not resect more than blue discolored and necrotic skin, 35% also resected red-colored skin, and 21% all skin overlying the affected fascia, including normal colored skin. Respondents working in a hospital with a burn center tended to preserve more skin, whereas plastic surgeons chose more often for skin resection compared to general surgeons. Conclusions: By using a novel approach to a survey, the authors demonstrate the existence of extensive practice variety regarding the approach to debridement of NSTI among Dutch general and plastic surgeons. Consensus is needed, followed by targeted education of surgeons

Outcomes of Meek micrografting versus mesh grafting on deep dermal and full thickness (burn) wounds: Study protocol for an intra-patient randomized controlled trial

Introduction Autologous split thickness skin grafting is the standard-of-care for most deep dermal and full thickness skin defects. Historically, mesh grafting is used to expand skin grafts for smaller defects and other techniques such as Meek micrografting is used to enable expansion for larger skin defects. Yet, Meek micrografting is increasingly used for smaller skin defects as well. Both techniques are frequently used, especially in burn centers, but evidence on which one is preferable for relative smaller skin defects is lacking. Therefore, an intra-patient randomized controlled trial was designed to adequately compare multiple outcomes of the Meek micrografting and mesh grafting techniques. Materials and methods A multicenter intra-patient controlled randomized trial is being performed in two burn centers (the Netherlands and Belgium) to compare multiple outcomes of Meek micrografting and mesh grafting burns or skin defects. Study registration number (NL74274.029.20). Adult patients with a (burn) wound and an indication for surgical excision and skin grafting were screened for inclusion. In total 70 patients will be included and the primary outcome is scar quality twelve months post-surgery assessed by the Patient and Observer Scar Assessment Scale. Moreover, graft take, re-epithelialization, infection rate, donor site size and patients’ preference are also measured within hospital admission, on 3 months and 12 months post-surgery. Discussion This is the first randomized trial that is intra-patient controlled, which enables a proper comparison between both skin expansion techniques. The results of this study will contribute to the clarification of the indications of both techniques and ample attention is paid for the patients’ opinion on the surgical treatment options

Long-term testicular position and growth of acquired undescended testis after prepubertal orchidopexy

The aim of the study was to determine long-term testicular position and growth of acquired undescended testis (UDT) after prepubertal orchidopexy. Patients who had undergone prepubertal orchidopexy for acquired UDT at our hospital between 1986 and 1999 were recruited to assess long-term testicular position and volume. Testis position was assessed by physical examination. Testis volume was measured with Prader orchidometry and ultrasound and was compared with normative values reported in the literature. A total of 105 patients (aged 14.0-31.6 years) were included with 137 acquired UDT (32 bilateral, 33 left sided, and 40 right sided). All but 1 of the orchidopexied testes (99.3%) were in low scrotal position. The mean volume of the orchidopexied testes in unilateral UDT (n = 73, 10.57 ± 3.74 mL) differed significantly from the size of the testes at the contralateral side (14.11 ± 4.23 mL) (P = .000). The operated testes (10.28 ± 3.45 mL) were smaller than the mean adult testis volume reported in the literature (13.4-13.6 mL; cutoff, 13.2 mL). Testis position after prepubertal orchidopexy for acquired UDT was nearly always low scrotal. The volume of the orchidopexied testes was smaller than both the volume of the contralateral testes and the normative values reported in the literatur

The Independent Functioning of the Orchidopexied Congenital Undescended Testis as Assessed by Positron Emission Tomography/Computed Tomography

Fertility after orchidopexied undescended testes (UDT) is impaired. Although fertility parameters are known to be more favorable in unilateral cases than in bilateral cases, the exact contribution of the unilateral orchidopexied UDT to fertility is unknown. We used testicular 18 F-fluoro-2-deoxyglucose ( 18 F-FDG)-uptake assessed by positron emission tomography/computed tomography (PET/CT) to investigate the function of the orchidopexied unilateral congenital UDT, compared to its normally descended counterpart. We hypothesize that the contribution of the orchidopexied unilateral congenital UDT to fertility in adulthood is low. Eleven men who underwent orchidopexy for congenital UDT at the age of 1.9 ± 1.4 (range, 4.5 months -4.0) years were seen in follow-up at the age of 24.1 ± 2.3 (20.6-28.0) years. All underwent physical examination, testicular ultrasonography and PET/CT. Testicular 18 F-FDG-uptake was expressed as the peak Standardized Uptake Value (SUV peak ). The mean SUV peak of the orchidopexied UDT was 2.74 ± 0.48 (2.13-3.47), which was significantly lower than its counterpart (P = 0.021). Besides, there was no correlation between the testicular volume and the SUV peak . The orchidopexied congenital UDT has been shown to be less metabolically active than its contralateral counterpart. Nevertheless, we suggest that the operated testes function to some degree
