Background: Inguinal hernia repair is a common surgical procedure, with more than 20 million cases yearly. Choice between mesh types varies in clinical practice. To compare light-weight polypropylene (LW-PP, 34-36 g/m2) and heavy-weight polypropylene (HW-PP, 95 ​g/m2) meshes., Methods: Data from patients who underwent open inguinal hernia repair between 2020 and 2022. Selection criteria ensured homogeneity. Endpoints were to assess the impact of different mesh weights on overall health-related quality of life (HRQoL), using Short Form 36 (SF-36), and to monitor postoperative complications., Results: Two hundred patients were included in both groups. Lateral and direct hernias occurred in 60.5 ​% and 39.5 ​%. According to EHS, 31.5 ​%, 22.3 ​% and 46.2 ​% were classified as size 1, 2, 3. Follow-up showed similar HRQoL at 30-days, with a favorable trend towards LW-PP mesh offering fewer limitations, better comfort, and improved general health after 12-months. No difference in postoperative paresthesia, wound hematoma, and interference with daily activities., Conclusion: 1-year after surgery HRQoL evaluation highlights the non-inferiority of LW-PP. Mesh selection should be tailored, aiming at improving outcomes and postoperative comfort., (Copyright © 2024 The Authors. Published by Elsevier Inc. All rights reserved.)

Background: Rhinoplasty traditionally presents a challenge for plastic surgeons. The aim of this article is to describe a new alar base lining graft (ABLG) in augmentation rhinoplasty to prevent and treat alar retraction., Methods: In this study, the authors retrospectively reviewed patients treated with ABLG at their institution between July of 2019 and April of 2022. The authors describe their technique and graft. At a minimum follow-up time of 1 year, postoperative photographs were taken, and patients were reassessed, evaluating aspects such as global symmetry, shape, and contour of the nose. Patient satisfaction was investigated according to the rhinoplasty outcomes evaluation questionnaire., Results: A total of 42 patients were included in the study. They reported significant satisfaction with the aesthetic results, as demonstrated by the mean postoperative rhinoplasty outcomes evaluation score. Alar contracture in secondary rhinoplasty was treated successfully. None of the grafts was extruded or collapsed. Wounds healed without reported major infection., Conclusion: This study demonstrates that ABLG is safe, contributes to improved functional and aesthetic outcomes, results in a high patient satisfaction rate, and has a low rate of postoperative complications., Clinical Question/level of Evidence: Therapeutic, IV., (Copyright © 2024 by the American Society of Plastic Surgeons.)

Background: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a potentially life-threatening autoimmune disorder which is strongly associated with ovarian teratomas in young female patients. The primary aim is to highlight the importance of considering NMDAR encephalitis in the differential diagnosis of young female patients presenting with acute or subacute neuropsychiatric symptoms, especially when accompanied by ovarian teratomas., Case Description: This case report and literature review detail the presentation, diagnosis, and treatment of a 35-year-old G4P3 Indigenous woman who initially presented with neuropsychiatric symptoms and fever, having a history of extensive drug and alcohol use. Misdiagnosed initially, the patient's lack of response to standard treatments led to further investigations, revealing paraneoplastic anti-NMDAR encephalitis secondary to a left ovarian teratoma. The report examines the treatment regimen followed, including prednisolone, intravenous immunoglobulin, rituximab injections, and laparoscopic bilateral salpingo-oophorectomy., Conclusions: This case underscores the critical need for increased clinical vigilance for anti-NMDAR encephalitis in patients, particularly young females, presenting with neuropsychiatric symptoms and potential ovarian teratomas. The literature review accompanying the case report provides valuable insights into the presentation, diagnosis, and management of this complex condition. Lastly, this study emphasised the diagnostic challenges inherent in paraneoplastic neuropsychiatric syndromes, advocating for a multidisciplinary approach in similar clinical scenarios., (© 2024.

Background : Deep inferior epigastric perforator (DIEP) flap breast reconstruction is an increasingly popular technique, but controversy exists regarding the optimal use of closed suction drains (CSD) at the abdominal donor site. This narrative review synthesizes current evidence on CSD application, criteria for placement/removal, and complications in DIEP flap procedures. Alternative techniques and implications for postoperative care are also discussed. Methods : A systematic search was conducted in August 2024 across several databases to identify English language studies related to CSD use in DIEP flap breast reconstruction. Inclusion criteria consisted of original research on aspects such as CSD volume criteria, timing, complications, alternatives like progressive tension sutures, and impact on showering and patient outcomes. References from relevant papers were hand-searched. Results : The review found a lack of consensus on CSD protocols, with drainage volume triggering removal varying widely from 5 mL to 80 mL daily. While CSD may reduce seroma/hematoma formation, earlier removal (≤3 days) did not increase complications and shortened hospital stay. Progressive tension sutures show promise as an alternative, with evidence of comparable or reduced complications and improved recovery versus CSD. The safety of early showering with drains remains unclear. Conclusions : Although CSD aims to minimize postoperative complications, more rigorous randomized trials are needed to establish evidence-based practices for the timing of removal and demonstrate the efficacy of emerging drain-free techniques on patient-centered outcomes. Standardized criteria could reduce practice variability. Further research should also explore the long-term impact of drainage strategies on aesthetic and functional results.

Background: Thigh lift, first described by Lewis in 1957, consists of thigh recontouring by various strategies. In post-bariatric thigh lift (PBTL), the technical details become fundamental due to both patient comorbidities and increased risk of complications. Moreover, post-bariatric weight loss affects the thighs, resulting in significant tissue redundancy, inner excess, lower thigh deformity, later excess, and buttocks ptosis. With the present paper, a systematic review of PBTL procedures is reported and a comprehensive classification system is proposed, aiming to improve their medical and surgical management., Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) systematic review was carried out by searching the PubMed (MEDLINE) database from May 2004 to May 2024 using the search string "thighplasty OR thigh lift OR post-bariatric thighplasty OR (thigh lift AND weight loss) OR (thigh lift AND liposuction)". Original studies discussing PBTL with a minimum of three clinical cases were eligible for inclusion., Results: The final synthesis included 17 articles and 496 patients. The articles were published in the last 20 years. Several papers discussed significant PBTL surgical strategies and technical measures., Conclusions: PBTL is challenging because of both technical factors and complex comorbidities of post-bariatric patients. This comprehensive assessment of PBTL may help in choosing the appropriate treatment based on a patient's individual needs. Liposuction-assisted inner thigh lift with combined horizontal-vertical scars and skin-only excision is effective and versatile for most patients. However, select cases may benefit from alternative and more invasive strategies. Artificial intelligence is a topic of growing interest, and it will probably become increasingly relevant in PBTL., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background/Objectives : Abdominoplasties are prevalent surgical procedures for improving lower abdominal contours, necessitating effective pain management. Insufficient management can increase opioid usage, dependency risks, and adverse effects. This review investigates various strategies in abdominoplasty pain management, aiming to reduce opioid dependence and improve patient care. Methods : A comprehensive systematic literature search (MEDLINE, Cochrane, PubMed, Web of Science, EMBASE) was conducted, spanning from their inception to January 2024, using keywords such as 'abdominoplasty' and 'postoperative pain management'. Included studies focused on nonopioid interventions in adults, encompassing various study designs. Non-English publications and those not meeting outcome criteria were excluded. Bias in studies was assessed using specific tools for randomized and non-randomized trials. Results : Thirty-five studies, published between 2005 and 2024, were included, involving 3636 patients with an average age of 41.8. Key findings highlighted the effectiveness of transversus abdominis plane blocks in reducing opioid use and pain. Pain pump catheters also showed promise in improving pain management and reducing opioid dependency. Local anesthetics demonstrated varying degrees of efficacy, while other alternatives like ketamine and NSAIDs successfully reduced postoperative pain and opioid requirements. The bias assessment of the RCTs revealed "low" and "some concerns" ratings, indicating a need for more detailed methodology reporting and management of missing data. The cohort studies generally attained "moderate" risks of bias, primarily due to confounding variables and outcome data reporting. Conclusions : Nonopioid analgesics show potential in postoperative pain management for abdominoplasties, but further research is needed to confirm their effectiveness and optimize patient care.

Autologous breast reconstruction, especially using the deep inferior epigastric artery perforator (DIEP) flap, is increasingly seen as a reliable, safe, and long-term alternative to implant-based reconstruction. Despite the recognized advantages of the DIEP flap for breast reconstruction, successful realization demands excellent anatomical knowledge, a thorough understanding of autologous breast reconstruction concepts and advanced microsurgical skills. Given that the porcine model is widely employed in microsurgical training, our study aims to assess this model using validated outcomes, with the objective of evaluating the enhancement in a surgeon's learning curve following training with this model. Forty DIEP flaps were harvested on 20 swines by a single surgeon in "Pius Branzeu Center" (Timisoara, RO) and "Drazan Institute" (University of veterinary of Brno, CZ) laboratories for microsurgical training in 6months (January 2015-June 2015). Then we analyzed data from 40 DIEP flaps harvested by the same surgeon on first 20 consecutive patients undergoing DIEP flap breast reconstruction. Perforator dissection time, surgeon-determined dissection difficulty score (DDS) and venous congestion rate were collected for each flap in porcine model and in patients, then compared and analyzed. The mean of DDS score analysis in first and second swines group dissection resulted as statistically significant (P-value 0.0001), while it was not statistically significant between those analyzed in the second group of swines dissected and patients (P-value 0.8037). Reduction in perforator dissection time between the two swines' groups and in venous congestion rates from the first swines groups to the second to the human group resulted statistically significant too (P-value respectively 0.0001 and 0.0079). The porcine model has been used for a long time together with other animal models for microsurgical training. Our study confirms and objective by validated scores that it is a valid and reliable model, comparable to the human one and which mimics the dissection of human perforating vessels., (Copyright © 2024 Elsevier Masson SAS.

Background : Tumescent local anesthesia (TLA) is widely used in esthetic surgery due to its ability to reduce complications, eliminate the need for general anesthesia, provide effective pain control, and shorten hospitalization times. Methods : This study evaluates the use of TLA in 80 patients who underwent augmentation mastopexy between 2010 and 2022. A tumescent solution containing 500 mg lidocaine, 672 mg sodium bicarbonate, and 1 mg epinephrine in 1000 mL of saline was infiltrated, with an average of 300 mL per breast. The surgical technique involved creating a subpectoral pocket for textured round implants (250-400 cc), followed by careful hemostasis. Results : No patients required conversion to general anesthesia, and there were no signs of toxicity or major complications. Minor complications included wound dehiscence (6.2%), hematoma (2.5%), and capsular contracture (2.5%). Pain management satisfaction at 3 months post-surgery was rated as "outstanding" by 12.5% of patients, "excellent" by 67.5%, and "good" by 20%. The longest follow-up was 6 years, with no implant ruptures except one (1.2%). Conclusions : While the study did not include a control group or statistical analysis, the findings suggest that TLA is a safe and effective alternative to general anesthesia for augmentation mastopexy, providing excellent pain control and a low rate of complications.

Eyelid melanoma (EM) is a malignant neoplasm accounting for around 1% of eyelid malignancies. Because of its rarity, most of our knowledge of EM is currently based on studies of cutaneous melanomas located elsewhere. Accordingly, this study aimed to specifically evaluate EM characteristics, management strategies, and prognosis. A retrospective study was carried out on patients diagnosed with EM at Careggi University Hospital, Florence between May 2012 and May 2022. In addition, a systematic review of relevant literature was conducted, encompassing studies published from 2013 to 2023. Clinical, histopathological, therapeutical, and prognostic data were analyzed to assess the metastasis rate and the 5-year survival rate of patients with EM. Separate data were extracted for in situ and invasive disease. Our original study included 19 patients diagnosed with EM with a 5-year survival rate of 100% for in situ and 83.3% for invasive EM. The literature review identified five poorly detailed large database reviews and 14 original studies on EM with an overall 5-year survival rate of 79.7%. The present research indicates that EM is a challenging malignancy, but has a relatively better prognosis and easier management than other melanomas of the head and neck region. These are probably related to the anatomical location which leads to early diagnosis. Therefore, EM should be considered as a specific disease requiring dedicated treatment. Based on the personal authors' experience and comprehensive overview of the current knowledge, a dedicated protocol is proposed., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

Background and Objectives : Despite CTAs being critical for preoperative planning in autologous breast reconstruction, experienced plastic surgeons may have differing preferences for which side of the abdomen to use for unilateral breast reconstruction. Large language models (LLMs) have the potential to assist medical imaging interpretation. This study compares the perforator selection preferences of experienced plastic surgeons with four popular LLMs based on CTA images for breast reconstruction. Materials and Methods : Six experienced plastic surgeons from Australia, the US, Italy, Denmark, and Argentina reviewed ten CTA images, indicated their preferred side of the abdomen for unilateral breast reconstruction and recommended the type of autologous reconstruction. The LLMs were prompted to do the same. The average decisions were calculated, recorded in suitable tables, and compared. Results : The six consultants predominantly recommend the DIEP procedure (83%). This suggests experienced surgeons feel more comfortable raising DIEP than TRAM flaps, which they recommended only 3% of the time. They also favoured MS TRAM and SIEA less frequently (11% and 2%, respectively). Three LLMs-ChatGPT-4o, ChatGPT-4, and Bing CoPilot-exclusively recommended DIEP (100%), while Claude suggested DIEP 90% and MS TRAM 10%. Despite minor variations in side recommendations, consultants and AI models clearly preferred DIEP. Conclusions : Consultants and LLMs consistently preferred DIEP procedures, indicating strong confidence among experienced surgeons, though LLMs occasionally deviated in recommendations, highlighting limitations in their image interpretation capabilities. This emphasises the need for ongoing refinement of AI-assisted decision support systems to ensure they align more closely with expert clinical judgment and enhance their reliability in clinical practice.

Background: The regulatory landscape for plastic and cosmetic surgery across the country plays a crucial role in shaping the practices within its premises, ensuring patient safety, and maintaining ethical standards in the medical community. This review examines the distinct regulatory frameworks that govern Australia, United Kingdom (UK), and Italy practices, focusing on the nuances that influence the professional accountability and safety measures in place., Methods: A comprehensive scoping review was conducted, exploring the legal and regulatory frameworks governing plastic and reconstructive surgery in Australia, the UK, and Italy. Databases such as PubMed, Scopus, and Google Scholar were searched for relevant studies from infinity to May 2024, which were then analyzed to compare regulatory practices, qualification requirements, and their implications on patient safety and professional accountability., Results: Each country presents a unique set of regulations that reflect their individual medical, legal, and cultural contexts. In Australia, the Australian Health Practitioner Regulation Agency (AHPRA) and the Medical Board of Australia impose stringent criteria for differentiating between "cosmetic surgeons" and "plastic surgeons". The UK's approach, governed by the General Medical Council (GMC), emphasizes ethical conduct, informed consent, and transparent advertising. Italy's regulatory framework varies slightly with a specific focus on the qualifications and titles of practitioners., Conclusions: The study underscores the importance of stringent regulations in plastic and cosmetic surgery, advocating for enhanced regulatory measures and comprehensive education on the qualifications of practitioners. It is imperative that these standards are maintained and adapted as necessary to protect patients in the rapidly evolving landscape of cosmetic and plastic surgery across the different regions., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-24-244/coif).

Abdominal pain in patients with diverticular disease (DD) can be challenging in clinical practice. Patients with symptomatic uncomplicated diverticular disease (SUDD) and patients with a previous acute diverticulitis (PD) may share a similar clinical pattern, difficult to differentiate from irritable bowel syndrome (IBS). We used standardized questionnaires for DD (short and long lasting abdominal pain) and IBS (following Rome III Criteria) to assess clinical features of abdominal pain, in terms of presence, severity and length, in SUDD and PD patients. One hundred and forty-eight SUDD and 118 PD patients completed all questionnaires. Short-lasting pain was more frequent in SUDD than PD patients (p = 0.007). Number of long-lasting pain episodes was higher in SUDD (6.6 ± 11.9) compared to PD patients (3.4 ± 6.9) (p < 0.001). PD patients reported long-lasting pain more frequently in the lower left abdomen (p < 0.001), while in SUDD it was more frequently diffuse (p = 0.002) or localized in the lower right quadrant (p = 0.009). Features associated with long-lasting pain (fever, confinement to bed, consultations, antibiotic therapy, hospitalization) were more often reported in PD patients. IBS criteria were reported in 28.2% of patients and were more frequent in SUDD than PD patients (37.2% vs 17.1%, p < 0.001). SUDD and PD patients presented different pattern of abdominal pain (length, number of long lasting episodes, site and associated features), with a third reporting overlap with IBS. Further observational studies are needed to better characterize abdominal symptoms in DD patients, especially in those not fulfilling IBS criteria.Trial registration: The REMAD Registry is registered as an observational study in ClinicalTrial.gov (ID: NCT03325829)., (© 2024.

Background: Amyloidosis is characterized by extracellular amyloid protein deposition. When amyloidosis intersects with basal cell carcinoma (BCC), it introduces complex diagnostic challenges. This study explored the overlap between primary localized cutaneous amyloidosis (PLCA) and BCC, examining amyloid deposits in BCC, systemic amyloidosis risk in PLCA, and various treatment methods., Methods: Two case studies were discussed, followed by a literature review, in which PubMed, Web of Science, EMBASE, and the Cochrane Library databases were utilized. The search, covering studies from infinity up to January 2024, focused on "cutaneous amyloidosis," "basal cell carcinoma," and related terms. Articles in English detailing the clinical presentation, diagnostic methods, treatment, and outcomes of cutaneous amyloidosis mimicking BCC were included. Data extraction and synthesis were performed by two independent reviewers., Case Series: This study highlighted two cases exemplifying the complexity of diagnosing BCC and PLCA. The first case (a 64-year-old with a nodule on the cheek) and the second (a 67-year-old with a nodular lesion on the upper lip cheek) were initially suspected as BCC and were later identified as PLCA upon histopathological examination., Discussion: The diagnosis of amyloidosis within BCC nodules remains a diagnostic challenge. Although their coexistence is relatively prevalent, their local recurrence rates remain debatable. Various diagnostic and therapeutic approaches have been suggested, such as topical creams and phototherapy. However, none have garnered conclusive and consistent evidence to establish reliable clinical application., Conclusion: The findings emphasized the importance of considering alternative pathologies in differential diagnoses. Future research should focus on understanding systemic amyloidosis risks and optimizing care for both conditions., (Copyright © 2024. Published by Elsevier Ltd.)

Background: The integration of neck liposuction with FaceTite Manipulus Radiofrequency (RF) technology and buccal fat pad excision for enhanced neck rejuvenation promise heightened precision and efficacy in sculpting the neck and jawline. Neck liposuction, coupled with RF technology, provides controlled thermal energy for adipose tissue treatment and collagen remodeling, while buccal fat pad excision offers refined contouring of the lower face and neck. This integrated approach aims to optimize patient outcomes and advance the field of esthetic plastic surgery., Methods: A prospective study was conducted from 2016 to 2023 on 80 consecutive patients who presented to the author's private clinic and required neck remodeling surgery for esthetic purposes. Patients were monitored and clinic appointments were scheduled at intervals of 0, 1, 3, 6 and 12 months post-treatment for evaluation. A tape measure recorded submental length at 1 and 6 months, and a satisfaction survey was administered one week before surgery and after six months. Physicians assessed improvement using a five-point scale for patient satisfaction and a four-point scale for overall improvement., Results: All patients underwent successful RFAL treatment, consistently achieving satisfaction with the outcomes. The average reduction in submental length measured 23 mm during the 6-month follow-up period. Additionally, the removal of buccal fat pads played a pivotal role in facial slimming and enhancing the esthetics of the upper cheek region., Conclusions: The integration of neck liposuction with FaceTite RF technology and buccal fat pad excision offers a promising approach for enhanced neck rejuvenation and facial contouring. This combined method demonstrates heightened precision and efficacy in sculpting the neck and jawline, aiming to optimize patient outcomes and advance the field of esthetic plastic surgery., Level of Evidence Iv: This journal requires that authors assign a level of evidence to each article.

Fournier's gangrene (FG) is a rare form of necrotizing fasciitis of the perineal, genital, or perianal region. It is characterized by an aggressive course and high mortality rate, over 20%. FG demands immediate treatment including resuscitation maneuvers, intravenous antibiotic therapy and early surgical debridement. Background/Objectives : The gold-standard treatment for FG is surgical reconstruction. However, up to date, no precise guidelines exist. Thus, we decided to systematically review the literature, focusing on FG contemporary approaches to reconstructive surgery, aiming to analyze the various reconstructive strategies and their specific indications. Methods : A systematic review was carried out according to the PRISMA statement by searching various databases from April 2014 to April 2024, using the terms ''Fournier Gangrene OR Fournier Gangrene Reconstruction OR Fournier Gangrene Treatment OR Fournier Gangrene Plastic Surgery OR Necrotizing Fasciitis OR Necrotizing Fasciitis AND Reconstruction". The eligibility criteria included original studies aimed at discussing FG reconstruction with at least three clinical cases. Results : The final synthesis included 38 articles, and 576 reconstructions were described. Of these, 77.6% were minimally invasive strategies (direct closure, secondary healing, grafts, and local random flaps), while more invasive reconstructions (loco-regional flaps based on known vascular anatomy) were adopted in 22.4%. No free flaps were reported. Conclusions : FG requires immediate medical interventions including broad-spectrum antibiotic therapy, surgical debridement, adjuvant therapies, and reconstructive surgeries. Taking into account the anatomical characteristics of the inguinal-crural region, skin grafts and local random flaps could offer versatile and effective reconstructions for most FG cases, while the more invasive strategies should be reserved for very few cases. Future research is warranted to define an FG dedicated reconstruction protocol.

Background: Artificial intelligence (AI) has emerged as a powerful tool in various medical fields, including plastic surgery. This study aims to evaluate the performance of ChatGPT, an AI language model, in elucidating historical aspects of plastic surgery and identifying potential avenues for innovation., Methods: A comprehensive analysis of ChatGPT's responses to a diverse range of plastic surgery-related inquiries was performed. The quality of the AI-generated responses was assessed based on their relevance, accuracy, and novelty. Additionally, the study examined the AI's ability to recognize gaps in existing knowledge and propose innovative solutions. ChatGPT's responses were analysed by specialist plastic surgeons with extensive research experience, and quantitatively analysed with a Likert scale., Results: ChatGPT demonstrated a high degree of proficiency in addressing a wide array of plastic surgery-related topics. The AI-generated responses were found to be relevant and accurate in most cases. However, it demonstrated convergent thinking and failed to generate genuinely novel ideas to revolutionize plastic surgery. Instead, it suggested currently popular trends that demonstrate great potential for further advancements. Some of the references presented were also erroneous as they cannot be validated against the existing literature., Conclusion: Although ChatGPT requires major improvements, this study highlights its potential as an effective tool for uncovering novel aspects of plastic surgery and identifying areas for future innovation. By leveraging the capabilities of AI language models, plastic surgeons may drive advancements in the field. Further studies are needed to cautiously explore the integration of AI-driven insights into clinical practice and to evaluate their impact on patient outcomes., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Background: Abdominoplasty is a critical aesthetic and functional procedure for individuals who have undergone massive weight loss. Numerous techniques have been proposed to optimize aesthetic results while minimizing complications., Methods: This prospective study examined 500 patients who underwent abdominoplasty during body-contouring procedures between 1 January 2018 and 31 December 2021 at a tertiary center. The Skin-Adipose Tissue-Muscle (SAM) protocol was employed to analyze the operative strategies and complication rates and compare them with the existing literature. Furthermore, patient satisfaction and aesthetic outcomes were measured one year post-operation using a comprehensive four-point questionnaire evaluated by the patients themselves and two independent surgeons., Results: Participants had an average age of 34.8 years and a mean BMI of 31.1 kg/m 2 . The surgeries included 328 full abdominoplasties and 172 T-inverted abdominoplasties. Notable complications included wound infection (4%), wound dehiscence (8.6%), tissue necrosis (0.6%), seroma (8.4%), and hematoma (2.6%). A higher BMI was correlated with an increased risk of complications and lower patient satisfaction. Data analysis was performed using Stata version 18 software., Conclusions: The increasing prevalence of obesity highlights an urgent need for more bariatric surgeries and subsequent abdominoplasties to mitigate the effects of massive weight loss. A crucial link between elevated BMI and a heightened risk of postoperative complications, emphasizing the necessity for standardized surgical protocols tailored to individuals with higher BMI, was noted. Innovatively, future studies must further investigate the intricate dynamics between BMI and surgical risks. Exploring and establishing uniform, adaptive surgical guidelines promise to revolutionize patient care by significantly reducing complications and enhancing recovery and satisfaction following abdominoplasty.

Background: Abdominoplasty is a common operation, used for a range of cosmetic and functional issues, often in the context of divarication of recti, significant weight loss, and after pregnancy. Despite this, patient-surgeon communication gaps can hinder informed decision-making. The integration of large language models (LLMs) in healthcare offers potential for enhancing patient information. This study evaluated the feasibility of using LLMs for answering perioperative queries., Methods: This study assessed the efficacy of four leading LLMs-OpenAI's ChatGPT-3.5, Anthropic's Claude, Google's Gemini, and Bing's CoPilot-using fifteen unique prompts. All outputs were evaluated using the Flesch-Kincaid, Flesch Reading Ease score, and Coleman-Liau index for readability assessment. The DISCERN score and a Likert scale were utilized to evaluate quality. Scores were assigned by two plastic surgical residents and then reviewed and discussed until a consensus was reached by five plastic surgeon specialists., Results: ChatGPT-3.5 required the highest level for comprehension, followed by Gemini, Claude, then CoPilot. Claude provided the most appropriate and actionable advice. In terms of patient-friendliness, CoPilot outperformed the rest, enhancing engagement and information comprehensiveness. ChatGPT-3.5 and Gemini offered adequate, though unremarkable, advice, employing more professional language. CoPilot uniquely included visual aids and was the only model to use hyperlinks, although they were not very helpful and acceptable, and it faced limitations in responding to certain queries., Conclusion: ChatGPT-3.5, Gemini, Claude, and Bing's CoPilot showcased differences in readability and reliability. LLMs offer unique advantages for patient care but require careful selection. Future research should integrate LLM strengths and address weaknesses for optimal patient education., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Periocular sebaceous carcinoma (PSC) is a rare, aggressive, and potentially metastatic adnexal malignancy. Due to the ability of PSC to resemble several benign and malignant conditions, diagnosis is often delayed or mistaken. In addition, even with a known diagnosis, choosing the right treatment is still an open debate. For this reason, we decided to review the most up-to-date literature on PSC and propose a dedicated procedural protocol to help clinicians when dealing with PSC. A PubMed search was carried out using the terms "Sebaceous Carcinoma", "Adnexal Periocular Cancer", "Sebaceous Carcinoma AND eyelid", "Periocular Sebaceous Carcinoma", and "Ocular Adnexa". Pertinent studies published in English from 1997 up to December 2022 were compared to the selection criteria and if suitable, included in this review. Through the initial search, 84 articles were selected. Of these, 36 were included in the final study. Several papers explored different diagnostic and therapeutic strategies regarding PSC diagnosis and management. In light of the current literature review and the multidisciplinary experience of three clinical centers, a dedicated procedural protocol is proposed. PSC diagnosis may be achieved through accurate clinical evaluation, but it requires histopathologic confirmation, which can be challenging. Dermoscopy, in vivo reflectance confocal microscopy, and optical coherence tomography may facilitate PSC clinical examination, while immunohistochemistry stains may support histological diagnosis. Appropriate disease staging is necessary before choosing the treatment, as local disease requires radically different treatment compared to advanced disease. In addition, recent innovations in nonsurgical treatments, including radio-chemotherapy, immunotherapy, and targeted therapy, may be a viable option in the most challenging cases., (© 2024 the International Society of Dermatology.)

Background: Diverticular disease (DD) represents a common gastrointestinal condition that poses a heavy burden on healthcare systems worldwide. A high degree of uncertainty surrounds the therapeutic approaches for the control of symptoms in patients with symptomatic uncomplicated diverticular disease (SUDD) and primary and secondary prevention of diverticulitis and its consequences., Objectives: To review the current knowledge and discuss the unmet needs regarding the management of SUDD and the prevention of acute diverticulitis., Eligibility Criteria: Randomized trials, observational studies, and systematic reviews on lifestyle/dietary interventions and medical treatment (rifaximin, mesalazine, and probiotics) of SUDD or prevention of acute diverticulitis., Sources of Evidence: The literature search was performed from inception to April 2023, without language restriction, following the modified Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) reporting guidelines. References of the papers selected were checked to identify additional papers of potential interest. The final list of references was evaluated by a panel of experts, who were asked to check for any lack of relevant studies., Charting Methods: Information on patient population, study design, intervention, control group, duration of the observation, and outcomes assessed was collected by two authors independently., Results: The review shows a high degree of uncertainty about therapeutic interventions, both dietary/lifestyle and pharmacological, in patients with SUDD, because of the scarcity and weakness of existing evidence. Available studies are generally of low quality, heterogeneous, and outdated, precluding the possibility to draw robust conclusions. Similarly, acute diverticulitis prevention has been seldom investigated, and there is a substantial lack of evidence supporting the role of dietary/lifestyle or pharmacological approaches to reduce the risk of diverticulitis., Conclusion: The lack of robust evidence regarding therapeutic options for gastrointestinal symptoms in SUDD patients and for primary and secondary prevention of acute diverticulitis remains an important unmet need in the management of DD., Competing Interests: R.

Introduction: Obesity is a chronic disease with significant health implications. Bariatric surgery is an effective treatment for obesity-related conditions. However, the timing of post-bariatric body contouring surgery remains uncertain., Materials and Methods: We conducted a retrospective study of 1336 patients who underwent bariatric surgery. We analyzed weight trends and variations after different types of bariatric procedures. The Pittsburgh Index was used to evaluate body contouring outcomes., Results: The majority of patients were women, and sleeve gastrectomy was the most common procedure. Weight loss varied depending on the surgery type, with different outcomes for male and female patients. The Pittsburgh Index remained stable in most cases., Conclusion: Our findings suggest that the timing of body contouring surgery should be tailored to the type of bariatric procedure performed. Abdominoplasty is recommended as a last procedure for sleeve gastrectomy patients, while gastric bypass patients are suitable candidates for early abdominoplasty. Biliopancreatic diversion patients should stabilize their weight before abdominoplasty. The Pittsburgh Index is a valuable tool for assessing the timing of post-bariatric plastic surgery. Further research is needed to optimize surgical planning and outcomes., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Purpose: The integration of artificial intelligence and machine learning technologies into the medical field has brought about remarkable advancements, particularly in the domain of clinical decision support systems. However, it is uncertain how they will perform as clinical decision-makers., Methods: This prospective cohort study evaluates the potential of incorporating ChatGPT-4 plus into the management of subcapital fifth metacarpal fractures. The treatment recommendations provided by ChatGPT-4 plus were compared with those of the two control groups-the attending clinic plastic surgeon and an independent expert panel. The primary outcome measures, operative or conservative, were compared between the groups. Intraclass correlation of 0.61 infers moderate reliability in the consistency of recommended management plans across all groups., Results: Key predictors for opting for operative management, regardless of the decision-maker, included clinical signs of scissoring, extension deficit, and radiographic evidence of intra-articular extension., Conclusions: These findings support the potential for artificial intelligence applications in enhancing diagnostic and treatment decisions., Type of Study/level of Evidence: Therapeutic IV., Competing Interests: No benefits in any form have been received or will be received related directly to this article., (© 2024 The Authors.)

Clear cell acanthoma (CCA) and squamous cell carcinoma (SCC) represent distinct entities within dermatological oncology, each posing unique diagnostic and therapeutic challenges. CCA is a rare, benign epidermal growth, often not associated with human papillomavirus (HPV) infection, whereas SCC, a more aggressive form of skin cancer, has been linked to both ultraviolet (UV) exposure and HPV. Understanding the co-occurrence of these conditions in a single patient can enhance diagnostic accuracy and therapeutic outcomes. We report a 64-year-old male who underwent an operation for a verruciform lesion in the right groin, which was diagnosed as HPV-positive CCA alongside keratinised SCC. A literature search across January 2024 revealed limited evidence directly linking HPV to CCA, suggesting a need for further investigation. The speculative association between HPV and CCA warrants deeper exploration, especially considering the potential for HPV to contribute to lesion development through indirect mechanisms. The coexistence of CCA and SCC in an elderly patient presents a unique clinical scenario. This emphasises the need for vigilant diagnosis and tailored treatment strategies, highlighting the gap in understanding the pathogenesis of CCA, particularly its potential association with HPV. Further research is crucial for elucidating the complex interactions governing these conditions and for developing targeted interventions.

Background: Atrophic scarring is a severe form-disfiguring sequela of acne, which can lead to negative effect on patients' life. Fractional microplasma radiofrequency (RF) has emerged as a promising modality, leveraging dermal fibroblast remodeling to enhance aesthetic results for scars and hyperpigmentation. This study evaluates the efficacy and safety of high-power fractional microplasma RF for atrophic acne scars, considering patient tolerance to procedural discomfort., Methods: In this prospective study, 95 Chinese patients with atrophic facial acne scars underwent three sessions of fractional microplasma RF treatment, with assessments at 1, 3, and 6 months post-treatment. Patients were categorized based on treatment power: Group A (50-70 W) and Group B (70-85 W). Efficacy was determined by three independent dermatologists using digital photographs and Echelle d'Evaluation Clinique des Cicatrices d'Acné (ECCA) scores, and patient-reported outcomes gauged satisfaction levels., Results: Eighty-six patients completed the study. Significant improvements were observed, with a reduction in ECCA scores from 107.21 to 42.27 (P<0.05), demonstrating notable scar amelioration across both groups, albeit with a superior outcome in Group B. All patients experienced transient side effects such as pain, erythema, and edema, deemed tolerable with no long-term adverse effects reported. The treatment was well-received, with high satisfaction rates, underscoring its efficacy and acceptable safety profile., Conclusion: Fractional microplasma RF therapy, particularly at higher power settings, is an effective and safe option for treating atrophic acne scars, offering significant aesthetic improvement with manageable discomfort. This modality presents a valuable addition to acne scar management strategies, especially for patients with darker skin tones seeking minimal downtime and reduced risk of hyperpigmentation., (© 2024 The Author(s).)

Background: Artificial intelligence (AI) has the potential to transform preoperative planning for breast reconstruction by enhancing the efficiency, accuracy, and reliability of radiology reporting through automatic interpretation and perforator identification. Large language models (LLMs) have recently advanced significantly in medicine. This study aimed to evaluate the proficiency of contemporary LLMs in interpreting computed tomography angiography (CTA) scans for deep inferior epigastric perforator (DIEP) flap preoperative planning., Methods: Four prominent LLMs, ChatGPT-4, BARD, Perplexity, and BingAI, answered six questions on CTA scan reporting. A panel of expert plastic surgeons with extensive experience in breast reconstruction assessed the responses using a Likert scale. In contrast, the responses' readability was evaluated using the Flesch Reading Ease score, the Flesch-Kincaid Grade level, and the Coleman-Liau Index. The DISCERN score was utilized to determine the responses' suitability. Statistical significance was identified through a t-test, and P-values < 0.05 were considered significant., Results: BingAI provided the most accurate and useful responses to prompts, followed by Perplexity, ChatGPT, and then BARD. BingAI had the greatest Flesh Reading Ease (34.7±5.5) and DISCERN (60.5±3.9) scores. Perplexity had higher Flesch-Kincaid Grade level (20.5±2.7) and Coleman-Liau Index (17.8±1.6) scores than other LLMs., Conclusion: LLMs exhibit limitations in their capabilities of reporting CTA for preoperative planning of breast reconstruction, yet the rapid advancements in technology hint at a promising future. AI stands poised to enhance the education of CTA reporting and aid preoperative planning. In the future, AI technology could provide automatic CTA interpretation, enhancing the efficiency, accuracy, and reliability of CTA reports., (© 2024 The Author(s).)

Introduction: The use of the dorsal hamate as a free osteochondral bone graft or vascularized bone flap has become the mainstay for large, comminuted middle phalanx volar lip fractures. To date, few studies have been conducted in the assessment of donor site morbidity for the hemi-hamate graft or flap, and none have discussed modes of repair or reconstruction of this donor site., Methods: A retrospective analysis of 14 hemi-hamate arthroplasty (HHA) procedures, including 6 vascularized and 8 non-vascularized grafts, from two surgeons was performed. Four hamate defect reconstruction techniques were utilized: no formal reconstruction, autologous bone grafting, gel foam, or synthetic bone substitute. The dorsal capsule was repaired with either extensor retinaculum grafting or by direct closure. Wrist range of motion, pain scores, and radiographic alignment were assessed., Results: At 6 months follow-up, all patients achieved full, pain-free wrist motion compared to the uninjured side, with visual analog scale pain scores of 0. Serial radiographs showed maintained carpal alignment without instability or subluxation. No differences based on the hamate defect reconstruction method or capsular repair technique was demonstrated., Conclusion: Safe return to pain free, unrestricted wrist function is achievable after HHA, regardless of hamate donor site management. Adequate dorsal capsular repair appears critical to prevent instability. Further study is needed to compare techniques, but choice may be guided by surgeon preference in the absence of clear evidence., Competing Interests: The authors declare no conflict of interests., (© 2024 The Author(s).)

Introduction: Augmentation rhinoplasty traditionally represents a serious challenge for plastic surgeons. The association with centrofacial lipofilling is a great approach to achieve harmonious, aesthetic results. The aim of this article is to describe our personal association between Augmentation Rhinoplasty and Centrofacial Lipofilling (ARCL) in non-Caucasian patients. Materials and Methods: In this study, we retrospectively reviewed patients treated with ARCL at our institution between January 2019 and December 2023. We described our personal approach and technique. At a minimum follow-up time of one year, post-operative pictures were taken, and patients were reassessed, evaluating aspects such as global symmetry, shape and contour of the nose, and facial harmony and rejuvenation; finally, patients' satisfaction was investigated according to the ROE questionnaire and the modified S-GAIS. Results: A total of 307 patients were included in the study. They reported a significant satisfactory aesthetic result in nasal image and facial harmony, as the mean postoperative ROE and S-GAIS score show. None of the grafts extruded or collapsed. Wounds healed without reported major infection. Conclusions: This study has demonstrated that ARCL is a safe approach that contributes to improve functional and aesthetic outcomes, has a high patient satisfaction rate, and limited post-operative complications.
