Search

Patients often use Google for their medical questions. With the emergence of artificial intelligence large language models, such as ChatGPT, patients may turn to such technologies as an alternative source of medical information. This study investigates the safety, accuracy, and comprehensiveness of medical responses provided by ChatGPT in comparison to Google for common questions about burn injuries and their management. A Google search was performed using the term "burn," and the top ten frequently searched questions along with their answers were documented. These questions were then prompted into ChatGPT. The quality of responses from both Google and ChatGPT was evaluated by three burn and trauma surgeons using the Global Quality Score (GQS) scale, rating from 1 (poor quality) to 5 (excellent quality). A Wilcoxon paired t-test evaluated the difference in scores between Google and ChatGPT answers. Google answers scored an average of 2.80 ± 1.03, indicating that some information was present but important topics were missing. Conversely, ChatGPT-generated answers scored an average of 4.57 ± 0.73, indicating excellent quality responses with high utility to patients. For half of the questions, the surgeons unanimously preferred their patients receive information from ChatGPT. This study presents an initial comparison of Google and ChatGPT responses to commonly asked burn injury questions. ChatGPT outperforms Google in responding to commonly asked questions on burn injury and management based on the evaluations of three experienced burn surgeons. These results highlight the potential of ChatGPT as a source of patient education., (© The Author(s) 2025. Published by Oxford University Press on behalf of the American Burn Association.

Background: Total knee arthroplasty (TKA) infection or exposure associated with soft tissue deficiency represents a challenging scenario for the reconstructive surgeon. The aim of the study is to determine the most successful reconstructive option for infected or exposed TKA comparing local muscle flaps (LMF), local fasciocutaneous flaps (LFF), and free muscle flaps (FMF)., Methods: A systematic review and single-arm network meta-analysis (PRISMA) was conducted to compare outcomes of complicated TKA requiring soft tissue coverage with either LMF, LFF and FMF. The protocol was registered on PROSPERO (CRD42023388731). PubMed, Embase, Web of Science and Cochrane Library were queried. MINORS criteria were employed for bias assessment. Outcomes included infection recurrence, TKA failure, above-knee amputation, and arthrodesis., Results: A total of 30 studies and 555 flaps were included. Pooled prevalence was 0.18 (95% CI: 0.11-0.26) for infection recurrence, 0.18 (95% CI: 0.11-0.28) for arthroplasty failure, 0.10 (95% CI: 0.08-0.13) for above-knee amputation and 0.10 (95% CI: 0.08-0.13) for arthrodesis. Local fasciocutaneous flaps demonstrated the lowest risk of infection recurrence (LFF = 0.04 ± 0.037, LMF = 0.27 ± 0.043, FMF = 0.26 ± 0.092), arthroplasty failure (LFF = 0.11 ± 0.068, LMF = 0.28 ± 0.045, FMF = 0.22 ± 0.094) and knee arthrodesis (LFF = 0.03 ± 0.027, LMF = 0.14 ± 0.03, FMF = 0.08 ± 0.06) after flap coverage of infected TKA. Free muscle flaps were associated with the lowest risk of above knee amputation (FMF = 0.08 ± 0.07, LFF = 0.10 ± 0.07, LMF = 0.11 ± 0.03). The mean MINORS score was 11.1 (95% CI: 11-12) with major weakness being the lack of prospective enrollment of the patients., Conclusion: Based on the available literature, when appropriate, LFF appear to be the best reconstructive choice for soft tissue reconstruction in complicated TKA., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Introduction: Hip osteoarthritis (OA) is a prevalent and debilitating condition, necessitating effective and safe treatment options. This systematic review aims to explore the potential of intra-articular mesenchymal stem cell (MSC) infiltrations as a therapeutic approach for hip OA., Methods: Following PRISMA guidelines, a systematic review was conducted, encompassing PubMed, Embase, and Cochrane Library databases. Inclusion criteria involved studies focusing on intra-articular MSC injections in patients with hip OA and reporting pain relief as an outcome measure. Quality assessment utilized the Newcastle-Ottawa scale and methodological index for non-randomized studies., Results: Ten studies were included in the review, exhibiting varied designs and sample sizes (316 patients). Outcome measures consisted of cartilage repair assessed through MRI and radiographies, pain scores (WOMAC, VAS, NRS), and functional improvements (HOS-ADL, OHS, FRI, PDQQ, LEFS). The studies reported favorable improvements in functional scores, pain relief, and cartilage repair/radiographic findings, with minimal reported adverse events., Conclusions: Intra-articular MSC infiltrations demonstrate promise as an effective and safe therapeutic intervention for managing hip OA, offering pain relief and functional enhancements. Nevertheless, limited high-quality studies and outcome measure variations underscore the need for further research to establish definitive treatment guidelines. Future investigations should address optimal MSC utilization, long-term outcomes, and potential complications to ensure the success of MSC-based therapies for hip OA management, ultimately improving patient outcomes. The findings provide valuable insights into the potential of MSC-based treatments for hip OA, advocating further rigorous research in this field., Trial Registration: The protocol was registered on PROSPERO database (CRD42023436973)., (© 2024.

Introduction: When planning for breast augmentation, it is important to consider not only implant choice, surgical technique and patient desires, but also the chest wall shape and deformities or irregularities, which remain often underestimated. They can be responsible for implant malposition and breast asymmetry after augmentation. Chondrocostal junction prominence is a minor but frequent chest wall deformity. The aim of this study is to report a new technique for sculpturing isolated chondrocostal prominence deformities in patients undergoing breast augmentation., Methods: A retrospective study was conducted to review surgical outcomes of a novel technique for costal prominence sculpturing and reshaping in patients undergoing breast augmentation. After reaching the subpectoral space, an inferiorly-based perichondral-periosteal flap is harvested just above the prominence. Once the deformity is corrected, the perichondral flap is repositioned over the sculpted rib., Results: A total of six patients presenting with isolated chondrocostal prominence underwent bilateral breast implant placement and costal reduction using the described technique. Three patients were primary augmentations while the remaining patients were two secondary breast augmentation and one augmentation mastopexy. No complications were reported. No additional pain was referred at the side of rib remodelling in comparison with the contralateral breast. All the patients were satisfied with cosmetic results., Conclusions: The described technique for contouring of isolated chondrocostal deformities is fast, easy reproducible and offers advantages over the standard partial rib reduction technique. It can prevent implant malposition and projection asymmetry, eventually enhancing breast augmentation outcomes., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Abstract: Burn injuries often require immediate assistance and specialized care for optimal management and outcomes. The emergence of accessible artificial intelligence technology has just recently started being applied to healthcare decision making and patient education. However, its role in clinical recommendations is still under scrutiny. This study aims to evaluate ChatGPT's outputs and the appropriateness of its responses to commonly asked questions regarding acute burn care when compared to the American Burn Association Guidelines. Twelve commonly asked questions were formulated by a fellowship-trained burn surgeon to address the American Burn Association's recommendations on burn injuries, management, and patient referral. These questions were prompted into ChatGPT, and each response was compared with the aforementioned guidelines, the gold standard for accurate and evidence-based burn care recommendations. Three burn surgeons independently evaluated the appropriateness and comprehensiveness of each ChatGPT response based on the guidelines according to the modified Global Quality Score scale. The average score for ChatGPT-generated responses was 4.56 ± 0.65, indicating the responses were exceptional quality with the most important topics covered and in high concordance with the guidelines. This initial comparison of ChatGPT-generated responses and the American Burn Association guidelines demonstrates that ChatGPT can accurately and comprehensibly describe appropriate treatment and management plans for acute burn injuries. We foresee that ChatGPT may play a role as a complementary tool in medical decision making and patient education, having a profound impact on clinical practice, research, and education., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Scarce data related to the drug survival of biologic agents in psoriasis patients aged ≥65 years is available., Objectives: To evaluate the drug survival of interleukin (IL)-23 or the IL-17 inhibitors approved for the treatment of moderate-to-severe psoriasis in elderly patients (aged ≥65 years), compared with younger adult patients (aged <65 years), and to identify clinical predictors that can influence the drug survival., Methods: This retrospective multicentric cohort study included adult patients with moderate-to-severe psoriasis, dissecting two-patient subcohorts based on age: elderly versus younger adults. Kaplan-Meier estimator and proportional hazard Cox regression models were used for drug survival analysis., Results: We included 4178 patients and 4866 treatment courses; 934 were elderly (1072 treatment courses), and 3244 were younger patients (3794 treatment courses). Drug survival, considering all causes of interruption, was higher in patients aged <65 years than in elderly patients overall (log-rank p < 0.006). This difference was significant for treatment courses involving IL-23 inhibitors (p < 0.001) but not for those with IL-17 inhibitors (p = 0.2). According to both uni- and multi-variable models, elder age was associated with an increased risk of treatment discontinuation (univariable analysis: HR: 1.229, 95% CI 1.062-1.422; p < 0.006; multivariable analysis: HR: 1.199, 95% CI 1.010-1.422; p = 0.0377). Anti-IL-23 agents were associated with a reduced likelihood of treatment discontinuation after adjusting for other variables (HR: 0.520, 95% CI 0.368-0.735; p < 0.001). Being previously treated with IL-17 inhibitors increased the probability of discontinuation., Conclusions: Elderly patients with psoriasis have an increased risk of biologic treatment discontinuation compared with younger adult patients, particularly, if being treated with IL-23 inhibitors. However, in stratified analyses conducted in elderly patients, IL-23 inhibitors showed higher drug survival rates than IL-17 inhibitors., (© 2024 European Academy of Dermatology and Venereology.)

Background : The reconstruction of large breasts carries a heightened risk profile. While skin-reducing mastectomy (SRM) techniques facilitate the correction of breast ptosis, they are frequently associated with a high incidence of vascular complications. This study compares two SRM techniques-the horizontal incision and the classic inverted T incision-by examining their clinical and surgical outcomes. Methods : We retrospectively analyzed data from 24 patients (30 breasts) who underwent SRM with immediate prosthetic reconstruction between 2019 and 2023 at the European Institute of Oncology in Milan, Italy. Our comparison focused on breast aesthetic outcome, reconstruction quality, complication rates (early and late), and patient satisfaction, utilizing the BREAST-Q questionnaire to gauge the latter. Results : Among the 24 patients included in the study, 16 (20 breasts) were treated with the inverted T technique, and 8 (10 breasts) with the horizontal incision approach. A higher overall complication rate was observed with the inverted T technique compared to the horizontal method, with early complications outnumbering late ones. The most common issues were recurrent seroma and skin necrosis leading to implant exposure. Notably, there were no cases of implant infection. Although the horizontal incision technique achieved slightly higher patient satisfaction scores, the difference was not statistically significant. Discussion : The inverted T and horizontal incision techniques each have unique benefits and drawbacks. Our findings indicate enhanced patient satisfaction and reduced complication rates with the horizontal incision technique. The selection of the technique should be customized based on the patient's individual risk factors, tissue quality, and preferences.

Background: The goals of mastopexy differ significantly from those of augmentation mammoplasty. Mastopexy is designed to lift and reshape the breasts, while augmentation mammoplasty is designed to increase the volume of the breasts. This conflict causes that one-stage augmentation mastopexies showed a revision rate from 8.7 to 23.2%. The aim of our study is to present some technical refinements for reducing the risk of implant exposure and reoperation., Methods: We designed a retrospective matched cohort study, including 216 consecutive patients, undergone augmentation mastopexy between January 2013 and December 2022. We divided them in two groups: Group A undergone an inverted-T superomedial pedicled augmentation mastopexy and Group B undergone our inverted-T modified augmentation mastopexy. The groups were matched for clinical and surgical variables, with the surgical technique the only difference between the two., Results: Complications were registered in ten patients (9.3%) in Group A (two wound breakdowns at T with implant exposure and eight wound dehiscences), six of which required surgical revision. In contrast, only three patients (2.8%) in Group B reported a complication, which was wound dehiscence without implant exposure in all cases. None of the dehiscence required surgical revision. The difference between complication and revision rates was statistically significant., Conclusions: Separating the implant and the mastopexy dissection planes reduces the implant exposure and the reoperation rate in one-stage augmentation mastopexy., Level of Evidence Iii: This journal requires that authors assign a level of evidence to each article.

Background: Autologous tissue transfer is an effective option for breast reconstruction post-mastectomy, with microsurgical techniques continually evolving. However, a comprehensive analysis of the relationship between prolonged ischemia time during free flap-based breast reconstruction and increased postoperative complications is still lacking., Methods: A systematic review and meta-analysis were conducted following PRISMA guidelines. Methodological quality was evaluated using the MINORS criteria. Studies meeting inclusion criteria were analyzed for total complications, complete and partial flap loss, and secondary outcomes. Data heterogeneity and risk ratios were assessed., Results: Seventeen studies encompassing 5636 patients and 6884 free flaps were included. The mean age of patients was 49.43 years (95% CI: 48.27-50.60), with a mean BMI of 26.09 (95% CI: 21.97-30.21), and an average post-harvesting free flap ischemia time of 70.35 min (95% CI: 56.71-83.98). These analyses revealed a heightened risk of total complications (RR: 1.99, 95% CI: 1.61-2.46), complete flap loss (RR: 3.15, 95% CI: 1.32-7.52), partial flap loss (RR: 1.91, 95% CI: 0.92-4.00), hematoma (RR: 1.79, 95% CI: 0.96-3.32), and infection (RR: 2.12, 95% CI: 1.32-3.42) in cases with ischemia time exceeding 60 min. Venous complications predominated in free flap failure cases., Conclusions: Effectively managing ischemia time could be crucial in free flap breast reconstruction to potentially reduce postoperative complications. Although there is a correlation between managing ischemia time and reducing postoperative complications, further research is needed to investigate the possible causation behind this relationship., Level of Evidence I: This journal requires that authors assign a level of evidence to each article.

Hand burns have a significant impact on the long-term function of burn patients. Recently, new protocols and technologies, such as dermal substitutes, have been introduced for the treatment of hand burns. This cross-sectional study investigates the preferred current management of acute hand burns and the role of dermal substitutes in treatment. A 10-question survey related to acute hand burns management was sent to 64 directors of American Burn Association (ABA)-verified burn centers. A total of 51.6% (n=33) directors of ABA-verified burn centers responded to the survey. For the treatment of superficial partial-thickness hand burns, 90.9% preferred a non-operative approach. Conversely, most respondents chose a single-stage excision and skin graft for deep partial-thickness hand burns (75.8%) and full-thickness hand burns (51.5%). However, for full-thickness hand burns, some surgeons prefer a two-stage reconstruction involving excision and placement of a skin substitute (27.3%) or allograft (9.1%), followed by a skin graft. Only 6.1% would utilize a three-stage reconstruction involving excision and allograft, excision and skin substitute, followed by skin grafting. Among surgeons who used skin substitutes (n=26), Integra (42.3%) and Novosorb Biodegradable Temporising Matrix (BTM) (23.1%) were preferred. The top reasons for choosing one specific dermal substitute were surgeon's preference (n=20; 76.9%) and cost (n=9; 34.6%). While a conservative non-operative approach is preferred for superficial partial-thickness hand burns, excision and skin grafting as a one-stage procedure remains the most common strategy for deep partial-thickness and full-thickness hand burns., (© The Author(s) 2024.

Background: Free flap reconstruction in acute burns is high risk but often required for limb salvage and coverage of vital structures. Prior studies have shown a flap loss rate up to 44%. This study aimed to compare the complications associated with muscle and fasciocutaneous free flaps in acute burn reconstruction., Methods: A systematic review and meta-analysis was conducted according to PRISMA guidelines and registered on the PROSPERO database (CDR42023471088). The databases accessed were Embase, PubMed, Web of Science, and Cochrane Library. The primary outcome was free flap failure rate based on flap type. Secondary outcomes included venous congestion, arterial thrombosis, amputation, and need for reintervention., Results: Twelve studies with 181 free flaps were included: 87 muscle flaps and 94 fasciocutaneous flaps. Muscle flaps had a higher risk ratio (RR) for total flap loss [RR: 2.32, 95% confidence interval (CI): 1.01-5.32, P = 0.04], arterial thrombosis (RR: 3.13, 95% CI: 1.17-8.42, P = 0.02), and amputations (RR: 8.89, 95% CI: 1.27-70.13, P = 0.03) compared with fasciocutaneous flaps. No significant differences were found in venous thrombosis (RR: 1.33, 95% CI: 0.37-4.78, P = 0.65) or need for reinterventions (RR: 1.34, 95% CI: 0.77-2.32, P = 0.29)., Conclusions: Muscle flaps in burn injuries are associated with higher risks of flap failure, arterial thrombosis, and amputations. Fasciocutaneous free flaps in acute burns seem to be safer with better outcomes, though further research is needed to confirm these findings., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

Background: Free tissue transfer is usually considered as a last resort in severe burn cases, when skin substitutes and local flaps are not viable options. Prior studies have demonstrated a free flap loss rate ranging from 0% to 44%. The aim of this study is to identify the ideal timing to perform free flap reconstruction in acute burn-related injuries to minimize free flap loss., Methods: A systematic review and meta-analysis was performed and reported according to PRISMA guidelines. PubMed, Embase, Web of Science, and Cochrane Library databases were queried. The review protocol was registered on PROSPERO database (CRD42023404478). Three time intervals from day of injury were identified: (1) 0-4 days, (2) 5-21 days, and (3) 22 days-6 weeks. The primary outcome was total free flap loss., Results: A total of 17 articles met inclusion criteria. The analysis included 275 free flaps performed in 260 patients (88% men, 12% women) affected by acute burn injuries. The pooled prevalence of free flap failure in the three time intervals (0-4 days, 5-21 days, and 22 days-6 weeks) were 7.32% [95% confidence interval (CI): 2.38%-20.37%], 16.55% (95% CI: 11.35%-23.51%), and 6.74% (95% CI: 3.06%-14.20%), respectively., Conclusions: Free flap reconstruction carries a high risk of failure in patients with acute burn. However, timing of the reconstruction appears to influence surgical outcomes. Free flap reconstruction performed between 5 and 21 days from burn injury had a trend toward higher flap loss rates and should be discouraged., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

Background: Free tissue transfer is often considered a last resort in burn reconstruction due to its complexity and associated risks. A comprehensive review on free flap outcomes in delayed burn reconstruction is currently lacking. The study aimed to evaluate the available evidence on the failure and contracture recurrence rates in free flap delayed burn reconstruction., Methods: A systematic review and meta-analysis was conducted and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The protocol was registered on PROSPERO (CRD42023404478). The following databases were accessed: Embase, PubMed, Web of Science, and Cochrane Library. The measured outcomes were free flap loss and contracture recurrence rate., Results: Of the 1262 retrieved articles, 40 qualified for inclusion, reporting on 1026 free flaps performed in 928 patients. The mean age was 29.25 years [95% confidence interval (CI), 24.63-33.88]. Delayed burn reconstruction was performed at an average of 94.68 months [95% CI, - 9.34 to 198.70] after initial injury, with a follow-up period of 23.02 months [95% CI, 4.46-41.58]. Total flap loss rate was 3.80% [95% CI, 2.79-5.16] and partial flap loss rate was 5.95% [95% CI, 4.65-7.57]. Interestingly, burn contracture recurrence rate was 0.62% [95% CI, 0.20-1.90]., Conclusions: This systematic review provides a comprehensive evaluation of the free flap outcomes in delayed burn reconstruction. The flap loss rate was relatively low, given the complexity of the procedure and potential risks. Furthermore, burn contracture rate was found to be extremely low. This study demonstrates that free flaps are a safe and effective option for delayed burn reconstruction., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

Artificial intelligence and large language models (LLMs) have recently gained attention as promising tools in various healthcare domains, offering potential benefits in clinical decision-making, medical education, and research. The Advanced Burn Life Support (ABLS) program is a didactic initiative endorsed by the American Burn Association, aiming to provide knowledge on the immediate care of severely burn patients. The aim of the study was to compare the performance of three LLMs (ChatGPT-3.5, ChatGPT-4, and Google Bard) on the ABLS exam. The ABLS exam consists of 50 questions with 5 multiple-choice answers. The passing threshold is 80% of correct answers. The 3 LLMs were queried with the 50 questions included in the latest version of the ABLS exam, on July 18th, 2023. ChatGPT-3.5 scored 86% (43 out of 50), ChatGPT-4 scored 90% (45 out of 50), and Bard scored 70% (35 out of 50). No difference was measured between ChatGPT-3.5 and ChatGPT-4 (P = .538) and between ChatGPT-3.5 and Bard (P = .054), despite the borderline P-value. ChatGPT-4 performed significantly better than Bard (P = .012). Out of the 50 questions, 78% (n = 39) were direct questions, while 12% (n = 11) were presented as clinical scenarios. No difference in the rate of wrong answers was found based on the type of question for the 3 LLMs. ChatGPT-3.5 and ChatGPT-4 demonstrated high accuracy at the ABLS exam and outperformed Google Bard. However, the potential multiple applications of LLMs in emergency burn and trauma care necessitate appropriate surveillance and most likely should represent a tool to complement human cognition., (© The Author(s) 2024.

Regenerative therapies such as fat grafting and Platelet Rich Plasma (PRP) have emerged as new options to tackle burn-related injuries and their long-term sequelae. Fat grafting is able to promote wound healing by regulating the inflammatory response, stimulating angiogenesis, favoring the remodeling of the extracellular matrix, and enhancing scar appearance. PRP can enhance wound healing by accelerating stages including hemostasis and re-epithelization. It can improve scar quality and complement fat grafting procedures. Their cost-effectiveness, minimal invasiveness, and promising results observed in the literature have made these tools as therapeutic candidates. The current evidence on fat grafting and PRP in acute and reconstructive burns is described and discussed in this study., Competing Interests: Disclosure The authors have no relevant commercial or financial conflicts of interest or funding sources., (Copyright © 2024 Elsevier Inc.

Acute burn reconstruction involves intricate strategies such as skin grafting and innovative technologies, addressing challenges in coverage and minimizing donor site morbidity. Despite being rarely used, flap reconstruction becomes necessary when critical structures are exposed, offering robust coverage and reducing complications. However, free flaps in acute burns face challenges, including a higher failure rate attributed to hyperinflammatory states and hypercoagulability. Surgical optimization strategies involve careful timing, patient preparation, and meticulous postoperative care. In delayed burn reconstruction, free flaps proved effective in functional and aesthetic restoration, with low flap loss rates and minimal contracture recurrence. Prefabricated and prelaminated flaps emerged as a solution for complex cases, ensuring the best functional and aesthetic possible outcomes in challenging facial burn reconstructions., Competing Interests: Disclosure The authors have no disclosures., (Copyright © 2024 Elsevier Inc.

Liposuction is a surgical procedure used to remove localized excess adipose tissue. According to The Aesthetic Society's latest annual report, liposuction is the most commonly performed cosmetic procedure. Despite its popularity, the existing literature lacks a unified understanding of the risks associated with liposuction. The aim of this study was to measure complications of liposuction. A systematic review and meta-analysis was reported according to PRISMA guidelines and registered on the PROSPERO database (CRD42023471626). The primary outcome was overall complication rate. The absolute risk for individual complications was also assessed. From 2957 articles, 39 studies were selected for analysis. In total, 29,368 patients were included, with a mean age of 40.62 years and mean BMI of 26.36 kg/m2. Overall, the rate of any complication was 2.62 (95% CI, 1.78-3.84). The most common complication was contour deformity, with a prevalence of 2.35% (95% CI, 1.05%-5.16%). The prevalence of hyperpigmentation was 1.49% (95% CI, 1.12%-1.99%), seroma 0.65% (95% CI, 0.33%-1.24%), hematoma 0.27% (95% CI, 0.12%-0.60%), superficial burn 0.25% (95% CI, 0.17%-0.36%), allergic reaction 0.16% (95% CI, 0.050%-0.52%), skin necrosis 0.046% (95% CI, 0.013%-0.16%), generalized edema 0.041% (95% CI, 0.0051%-0.32%), infection 0.020% (95% CI, 0.010%-0.050%), venous thromboembolism 0.017% (95% CI, 0.0060%-0.053%), and local anesthesia toxicity 0.016% (95% CI, 0.0040%-0.064%). Liposuction is a safe procedure with low complications, of which contour deformity is the most common. Raising awareness of specific risks can enhance surgical outcomes and improve patient-physician understanding., (© The Author(s) 2024.

Background: This study evaluates the potential of ChatGPT and Google Bard as educational tools for patients in orthopedics, focusing on sports medicine and pediatric orthopedics. The aim is to compare the quality of responses provided by these natural language processing (NLP) models, addressing concerns about the potential dissemination of incorrect medical information., Methods: Ten ACL- and flat foot-related questions from a Google search were presented to ChatGPT-3.5 and Google Bard. Expert orthopedic surgeons rated the responses using the Global Quality Score (GQS). The study minimized bias by clearing chat history before each question, maintaining respondent anonymity and employing statistical analysis to compare response quality., Results: ChatGPT-3.5 and Google Bard yielded good-quality responses, with average scores of 4.1 ± 0.7 and 4 ± 0.78, respectively, for sports medicine. For pediatric orthopedics, Google Bard scored 3.5 ± 1, while the average score for responses generated by ChatGPT was 3.8 ± 0.83. In both cases, no statistically significant difference was found between the platforms ( p = 0.6787, p = 0.3092). Despite ChatGPT's responses being considered more readable, both platforms showed promise for AI-driven patient education, with no reported misinformation., Conclusions: ChatGPT and Google Bard demonstrate significant potential as supplementary patient education resources in orthopedics. However, improvements are needed for increased reliability. The study underscores the evolving role of AI in orthopedics and calls for continued research to ensure a conscientious integration of AI in healthcare education.

Background: Body contouring surgery after massive weight loss has emerged a safe and reliable option to improve self-esteem, social life, work ability, physical activity, and sexual activity, and it is considered as an essential step in the multidisciplinary approach to morbid obesity.

Background: Upper extremity limb loss profoundly impacts a patient's quality of life and well-being and carries a significant societal cost. Although osseointegration allows the attachment of the prosthesis directly to the bone, it is a relatively recent development as an alternative to conventional socket prostheses. The objective of this review was to identify reports on osseointegrated prosthetic embodiment for transhumeral amputations and assess the implant systems used, postoperative outcomes, and complications., Methods: A systematic review following PRISMA and AMSTAR guidelines assessed functional outcomes, implant longevity and retention, activities of daily living, and complications associated with osseointegrated prostheses in transhumeral amputees., Results: The literature search yielded 794 articles, with eight of these articles (retrospective analyses and case series) meeting the inclusion criteria. Myoelectric systems equipped with Osseointegrated Prostheses for the Rehabilitation of Amputees implants have been commonly used as transhumeral osseointegration systems. The transhumeral osseointegrated prostheses offered considerable improvements in functional outcomes, with participants demonstrating enhanced range of motion and improved performance of activities compared with traditional socket-based prostheses. One study demonstrated the advantage of an osseointegrated implant as a bidirectional gateway for signal transmission, enabling intuitive control of a bionic hand., Conclusions: Osseointegrated prostheses hold the potential to significantly improve the quality of life for individuals with transhumeral amputations. Continued research and clinical expansion are expected to lead to the realization of enhanced efficacy and safety in this technique, accompanied by cost reductions over time as a result of improved efficiencies and advancements in device design., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

Background: ChatGPT, an artificial intelligence (AI) chatbot that uses natural language processing (NLP) to interact in a humanlike manner, has made significant contributions to various healthcare fields, including plastic surgery. However, its widespread use has raised ethical and security concerns. This study examines the presence of ChatGPT, an artificial intelligence (AI) chatbot, in the literature of plastic surgery., Methods: A bibliometric analysis and scoping review of the ChatGPT plastic surgery literature were performed. PubMed was queried using the search term "ChatGPT" to identify all biomedical literature on ChatGPT, with only studies related to plastic, reconstructive, or aesthetic surgery topics being considered eligible for inclusion., Results: The analysis included 30 out of 724 articles retrieved from PubMed, focusing on publications from December 2022 to July 2023. Four key areas of research emerged: applications in research/creation of original work, clinical application, surgical education, and ethics/commentary on previous studies. The versatility of ChatGPT in research, its potential in surgical education, and its role in enhancing patient education were explored. Ethical concerns regarding patient privacy, plagiarism, and the accuracy of information obtained from ChatGPT-generated sources were also highlighted., Conclusion: While ethical concerns persist, the study underscores the potential of ChatGPT in plastic surgery research and practice, emphasizing the need for careful utilization and collaboration to optimize its benefits while minimizing risks., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Background: Loss of vision and other ocular defects are a concern with eyelid burn sequelae. This most commonly progresses from eyelid contracture to cicatricial ectropion and lagophthalmos. When left untreated, these may lead to exposure keratitis, ulceration, infection, perforation, and loss of vision. In the case of full-thickness eyelid burns, release and grafting are required. However, there is a paucity of studies on outcomes in eyelid burn surgery treatment, despite concern for permanent ocular damage or loss of vision. The aim of the study is to describe the complication rates in burn eyelid reconstruction at a single center for 14 years., Methods: A retrospective cohort study was performed of all patients who had sustained eyelid burns and required reconstruction between April 2009 and February 2023. Medical records were obtained from patients' charts. Collected data include demographics, medical history, type of injury, indication for surgery, procedure performed, and complications., Results: A total of 14 patients and 25 eyelids underwent eyelid reconstruction of the 901 total patients with burn-related injuries requiring plastic surgery reconstruction. These patients underwent 54 eyelid surgeries with a mean follow-up time of 13.1 ± 17.1 months. Patients were 71% men and 29% women, with a mean age of 45.1 ± 15.6 years. In 53.7% (n = 29) of the cases, the simultaneous reconstruction of both the upper and lower eyelids was necessary. The reconstruction of the upper and lower eyelid alone represented a smaller percentage (25.9% and 20.4%, respectively). On average, the patients received 3.9 ± 3.5 eyelid surgeries. The overall complication rate was 53.7% (n = 29). The most common complication was ectropion (42.6%, n = 23). Other complications included eye injury (25.9%, n = 14), lagophthalmos (24.1%, n = 13), local infection (7.4%, n = 4), and graft loss (5.6%, n = 3)., Conclusion: Periorbital burns represent a major challenge that may require complex surgical intervention. Full-thickness skin graft remains the standard of care for patients with eyelid burns. However, there is a high incidence of ectropion that may require reoperation. Further studies examining the conditions of successful eyelid burn procedures may provide guidance on when patients may benefit from eyelid reconstruction during their burn treatment., Competing Interests: Conflict of interest: The authors declare that they have no conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Introduction: Endogenous endophthalmitis (EE) is a severe intraocular infection due to hematogenous spread of bacteria from an extraocular site. Recognition of the primary source of hematogenous spread of bacteria is essential to establish an adequate therapy and avoid other major complications. Infected cutaneous tumor has never been reported as a possible source of EE., Purpose: To describe the first case of EE due to hematogenous spread of methicillin-sensitive Staphylococcus aureus from an infected cutaneous basal cell carcinoma. Systemic antibiotic therapy and surgical excision of the cutaneous lesion were performed., Conclusion: Severe and long-standing skin infections should be considered as a rare cause of EE.

Introduction: Burn neck contractures pose a great challenge for reconstructive surgeons. A paucity of literature exist regarding long-term outcomes based on different surgical management strategies. The aim of this study was to evaluate the long-term outcomes of the treatment of neck burn scar contractures and evaluate surgical strategies according to their long-term effectiveness and associated complications., Methods: A retrospective cohort study was conducted to review outcomes of neck contractures release after burn injury. All patients operated on between January 2009 and February 2023 at a single institution were included., Results: A total of 20 patients developed neck burn scar contracture and were included in this study. The mean age was 32.9 ± 20.3 years. The burn injuries were most commonly thermal (n = 19, 95%). All burn injuries were full-thickness burns, with an average neck defect size of 130.5 ± 106.0 cm2. Overall, 45 surgical scar release procedures were performed on the 20 patients who developed a neck contracture. Patients underwent 1.65 ± 1.04 surgeries on average to address neck contracture. Although 25% of patients only received 1 surgery to treat neck contracture, some patients underwent as many as 8 surgeries. Contracture recurrence (CR) was the most common complication and occurred in 28.9% of the cases. The mean percentage total body surface area did not significantly differ in CR patients (26.7% ± 14.9%) and no-CR patients (44.5% ± 30.2%). However, there was a significant difference (P = 0.01) in the average neck defect size between CR patients (198.5 ± 108.3 cm2) and no-CR patients (81.1 ± 75.1 cm2)., Conclusions: This study showed that risk factors for initial burn scar contractures may differ from those associated with CR, highlighting the importance of neck defect size as a predictor. The study also examines various surgical approaches, with Z-plasty showing promise for managing CR. However, the absence of data on neck range of motion is a limitation. This research underscores the complexity of managing CR and emphasizes the need for ongoing postoperative monitoring., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Hyperpigmented scars, particularly in exposed body areas, can be difficult to conceal and may evoke psychological distress. While the precise causes of scar dyschromia are not fully understood, alterations in melanogenic activity appear to hold more significance than changes in melanocyte quantity. Current treatments encompass laser interventions. However, it is essential to consider their costs and potential complications in relation to their limited proven effectiveness. Fat grafting has gained interest as a scar modulation technique due to its regenerative properties, and its efficacy in reducing scar hyperpigmentation is currently under investigation., Methods: A systematic review and meta-analysis was reported according to PRISMA guidelines. PubMed, Embase, and Cochrane Library databases were accessed. PROSPERO registration number is CRD42023457778. The primary outcome was a change in scar pigmentation after fat grafting. Pigmentation changes after fat grafting were calculated using the standardized mean difference (SMD) between baseline and postoperative scores according to POSAS and VSS scales. Bias assessment was conducted according to the National Institute for Health and Clinical Excellence quality assessment tool., Results: A total of 8 articles meeting inclusion and exclusion criteria were identified, involving 323 patients with hyperpigmented scars treated with fat grafting. A significant difference in scar pigmentation was noted after treatment with fat grafting according to observers' ratings, with a SMD of - 1.09 [95% CI: - 1.32; - 0.85], p<0.01. The SMD for patient-reported scar pigmentation after treatment with fat grafting was - 0.99 [96% CI: - 1.31; - 0.66], p<0.01. Four studies provided objective measurements of melanin changes after fat grafting and revealed inconsistent findings compared to subjective observations., Conclusions: Fat grafting shows promise in ameliorating hyperpigmented scars based on subjective assessments, but further corroborating evidence from objective measures is required., Level of Evidence Iv: This journal requires that authors assign a level of evidence to each article.

Introduction: Oncoplastic surgery (OPS) allows wide excisions and accurate tumor resection and reduces breast deformities by immediate reconstruction of large defects. Superior pedicled mammaplasties allow excellent results in large breasts. Conversely, loco-regional flaps are the standard of care in small-to-medium breasts. However, both techniques show limitations in case of large resections of the lower pole, resulting in skin retraction and downward deviation of nipple and areola. We present a new technique for inferior pole reconstruction to overcome these limitations. It is called "the three-petal reconstruction" (3-PR)., Methods: Between September 2016 and May 2019, ten patients with invasive breast cancer of the lower pole underwent breast conservation and 3-PR., Results: The 3-PR was uneventful in all patients. No major or minor complications were recorded. Patient and surgeon evaluations scored as good to excellent in all cases. Surveillance examinations in the follow-up did not reveal calcifications nor any findings of suspicion within the reconstructed area., Conclusions: In case of very large defect of lower pole, the 3-PR reveals to be an easy, fast, reproducible method for inferior pole reconstruction. It can represent a niche between therapeutic mammaplasty and perforator flaps, and it could be added to existing available options for tailored reconstruction., Level of Evidence Iii: This journal requires that authors assign a level of evidence to each article.

Background: The radial forearm flap (RFF) is one of the most commonly used flaps in reconstructive surgery. Split-thickness skin grafting (STSG) has traditionally been used for closure of the forearm. However, full-thickness skin grafting (FTSG) has gained in popularity to achieve more satisfactory results. The aim of the study is to identify the best RFF donor site closure technique by comparing the functional and aesthetic outcomes of STSG and FTSG., Methods: PubMed and EMBASE databases were queried. Only studies comparing complications rate, functional and aesthetic outcomes between STSG and FTSG were included. The primary outcome was graft failure rate. Secondary outcomes included the aesthetic result and functionality of the forearm/wrist., Results: A total of 13 studies were included in this review, accounting for a total of 712 patients with mean age of 60.7 years. Overall, 348 patients underwent FTSG and 377 underwent STSG. The mean follow-up was 14.7 months. The rate of graft failure in FTSG was significantly higher compared to STSG (OR: 2.79, 95 % CI 1.38-5.65, p = 0.004). There was no significant difference in rate of tendon exposure (OR: 0.83, p = 0.65) and infection (OR: 1.37, p = 0.42). Regarding the aesthetic outcome, no significant difference between FTSG and STSG based on observer (SMD = -0.37, p = 0.17) and patient (SMD = -0.016, p = 0.93) assessment, respectively. Overall postoperative functional assessment showed a not severely impaired hand and arm function in both groups. Subjective evaluation of pain was similar between groups., Conclusion: FTSG is associated with higher risk of graft failure than STSG in RFF donor site closure, without significant improvement in aesthetic results., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2023 Elsevier Inc.

Abstract: A 10 year cohort of patients admitted to a verified burn unit were analyzed to assess the role of plastic surgeons in the operative management of those patients. All 3843patients were admitted during this study period. Of these, 1509 of those patients underwent surgical procedures. Plastic surgeons performed 658 operations on these patients, including acute and delayed reconstruction of hand and facial burn injuries. In this population, plastic surgeons played a critical role in acute and reconstructive burn injuries in anatomically complex areas. This series illustrates the need for plastic surgery training in burn care., Competing Interests: Conflict of interest: The authors declare that they have no conflicts of interest to disclose.

Background: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare complication associated with the use of breast implants. Breast implant illness (BII) is another potentially concerning issue related to breast implants. This study aims to assess the quality of ChatGPT as a potential source of patient education by comparing the answers to frequently asked questions on BIA-ALCL and BII provided by ChatGPT and Google., Methods: The Google and ChatGPT answers to the 10 most frequently asked questions on the search terms "breast implant associated anaplastic large cell lymphoma" and "breast implant illness" were recorded. Five blinded breast plastic surgeons were then asked to grade the quality of the answers according to the Global Quality Score (GQS). A Wilcoxon paired t-test was performed to evaluate the difference in GQS ratings for Google and ChatGPT answers. The sources provided by Google and ChatGPT were also categorized and assessed., Results: In a comparison of answers provided by Google and ChatGPT on BIA-ALCL and BII, ChatGPT significantly outperformed Google. For BIA-ALCL, Google's average score was 2.72 ± 1.44, whereas ChatGPT scored an average of 4.18 ± 1.04 (p < 0.01). For BII, Google's average score was 2.66 ± 1.24, while ChatGPT scored an average of 4.28 ± 0.97 (p < 0.01). The superiority of ChatGPT's responses was attributed to their comprehensive nature and recognition of existing knowledge gaps. However, some of ChatGPT's answers had inaccessible sources., Conclusion: ChatGPT outperforms Google in providing high-quality answers to commonly asked questions on BIA-ALCL and BII, highlighting the potential of AI technologies in patient education., Level of Evidence: Level III, comparative study LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.
