RESUMEN
INTRODUCTION: International data describes a changing pattern to trauma over the last decade, with an increasingly comorbid population presenting challenges to trauma management and resources. In Ireland, resource provision and management of trauma is being transformed to deliver a trauma network, in line with international best practice. Our hospital plays a crucial role within this network and is designated a Trauma Unit with Specialist Services (TUSS) to distinguish it from standard trauma units. METHODS: This study aims to describe the characteristics of patients and injuries and assess trends in mortality rates. It is a retrospective observational study of adult ICU trauma admissions from August 2010 to July 2021. Primary outcome was all-cause mortality at 30-days, 90-days, and 1 year. Secondary outcomes included length of stay, disposition, and complications. Patients were categorised by age, injury severity score (ISS), and mechanism of injury. RESULTS: In all, 709 patients were identified for final analysis. Annual admissions doubled since 2010/11, with a trough of 41 admissions, increasing to peak at 95 admissions in 2017/18. Blunt trauma accounted for 97.6% of cases. Falls <2 m (45.4%) and RTAs (29.2%) were the main mechanisms of injury. Polytrauma comprised 41.9% of admissions. Traumatic brain injury accounted for 30.2% of cases; 18.8% of these patients were transferred to a neurosurgical centre. The majority of patients, 58.1%, were severely injured (ISS ≥ 16). Patients ≥ 65 years of age accounted for 45.7% of admissions, with falls <2 m their primary mechanism of injury. The primary outcome of all-cause mortality reduced with an absolute risk reduction (ARR) of 8.0% (95% CI: -8.37%, 24.36%), 12.9% (95% CI: -4.19%, 29.94%) and 8.2% (95% CI: -9.64%, 26.09%) for 30-day, 90-day and 1-year respectively. Regression analysis demonstrated a significant reduction in mortality for 30-days and 90-days post presentation to hospital (P-values of 0.018, 0.033 and 0.152 for 30-day, 90-day and 1-year respectively). CONCLUSION: The burden of major trauma in our hospital is considerable and increasing over time. Substantial changes in demographics, injury mechanism and mortality were seen, with outcomes improving over time. This is consistent with international data where trauma systems have been adopted.

Background: Microsurgery is a technically demanding surgical discipline with a steep learning curve. Trainees have faced several difficulties due to less hands-on theater time and pandemic-related limits on access to technical training. To overcome this, trainees engaged in self-directed training, which requires an accurate self-assessment of skill. This study aimed to assess the ability of trainees to accurately self-assess their performance while performing a simulated microvascular anastomosis. Methods: Novice and specialist plastic surgery trainees performed a simulated microvascular anastomosis on a high-fidelity chicken femoral vessel model. Each participant objectively rated the quality of their anastomosis using the Anastomosis Lapse Index (ALI). Two expert microsurgeons subsequently blindly rated each anastomosis. To determine the accuracy of self-evaluation, self-scores and expert-scores were compared using a Wilcoxon signed-rank test. Results: Twenty-seven surgical trainees completed the simulation, with a mean time to completion (TTC) of 40.3 minutes (range 14.2-106.0 minutes). For the entire cohort, the median ALI self-score was 4 (range 3-10), while the median ALI expert-score was 5.5 (range 2.5-9.5). There was a significant difference between the ALI self-score and the expert-score (p<0.001). When grouped by experience level, there was no significant difference between self-score and expert-score within the specialist group, while there was a significant difference within the novice group (p=0.001). Conclusion: These findings suggest that specialist trainees are accurate assessors of their own microsurgical skills, but novice trainees tend to overestimate their technical skills. While novice trainees can engage in independent self-directed microsurgical training, they should seek expert feedback to ensure targeted training.
RESUMEN
BACKGROUND: Cutaneous squamous cell carcinoma (SCC) is an increasingly prevalent and potentially fatal disease with considerable implications if not recognized early and treated promptly. Several disease features contribute to a higher risk profile and adverse outcomes in affected patients. AIMS: Given the clinical observation that elderly males from rural communities often present with large SCCs of the scalp, we sought to investigate and describe features of disease and sociodemographic factors from a cohort of patients with scalp SCCs. METHODS: Histology reports of scalp primary SCCs were retrospectively assessed. Disease and demographic features were recorded. Descriptive statistics were generated, and statistical analyses (Fisher's exact, Mann-Whitney U and Spearman's rank test) were utilized to examine relationships between high-risk disease features and sociodemographic features. RESULTS: Ninety-three occurrences of scalp SCC in 61 patients were assessed. The average age at presentation was 78.81 years. Males were predominantly affected at a 14:1 ratio. Half of all tumours were greater than 2 cm (47/93 (50.54%)). The geographical distance from treatment was significantly associated with larger tumours at presentation. (rs = .34 P = 0.002). Recurrence and metastasis rates were determined amongst 188 patients with a primary scalp SCC, and low rates were observed (2.66% and 2.13%, respectively). CONCLUSIONS: Elderly males are inordinately affected by scalp SCC compared to females. Those living further from care exhibited larger tumours at presentation. Data from this study characterize features of SCC of the scalp and provide evidence to suggest that rural isolation may act as a mediator of high-risk presentation and larger tumour size.

Desmoid tumours are benign neoplasms of myofibroblasts, often occurring after soft-tissue trauma. Rarely, desmoid tumours can occur following operative intervention, including spine surgery. In this case report, we describe the first reported case of desmoid tumour following scoliosis corrective surgery in an adolescent.
RESUMEN
INTRODUCTION: The advent of wide-awake local anaesthesia has led to a reduced need for main theatre for trauma and elective plastic procedures. This results in significant cost-benefits for the institution. This study aims to show how a dedicated 7 days/ week plastic surgery procedural (PSP) unit, performing both elective and trauma surgeries, can lead to significant cost-benefits for the institution. METHODS: Retrospective review of all cases performed in the PSP unit between 1 September and 31 August 2018. We utilised hospital directory admissions data and the hospital's intranet operating theatre system to calculate hospital days saved. Cost analysis was performed using Saolta financial data. RESULTS: A total of 3058 operations were performed. Of these operations, 2388 cases were elective and 670 were trauma cases. The average waiting time for trauma cases for main operating theatre was 1.4 days, saving a total of 487 hospital days. The total savings associated with hospital bed days were 347,861. The estimated resource savings from performing a procedure in PSP compared with main theatre with regional anaesthesia were 529.00 and 391.00 without regional anaesthesia. The cost saved due to resources was therefore 337,226. The total cost-benefit associated with performing surgeries in PSP including hospital days and resources saved was calculated as 685,087. CONCLUSION: This study shows the benefit of performing elective and trauma operations in minor procedure units such as PSP. PSP results in a more efficient service, reducing waiting times for surgery, shorter hospital stay, reduced operating cost and an overall significant cost saving.

Introduction: Microsurgery is an essential element of Plastic Surgery practice. There is a paucity of studies assessing the impact of stress and cognitive distraction on technical microsurgical performance. The ability to complete cognitive and technical skills in parallel has not been assessed in a microsurgical setting. Aim: To test the hypothesis that cognitive distraction and external stressors negatively affect microsurgical performance in a high fidelity simulation setting. Materials/Methods: Fourteen surgeons across all levels of training undertook 2 microsurgical skills sessions, 1 month apart. Session one established baseline microsurgical skill. In session two, skills were assessed with the introduction of realistic operative room cognitive distractions (ORDIs). Outcome measures were efficiency and accuracy, measured by Time to Completion (TTC) and Anastomosis Lapse Index (ALI), respectively. Key Results: Fourteen participants (6 novices, 5 plastic surgery specialist trainees and 3 consultants) completed both microsurgical skills sessions. In total, 28-microvascular anastomosis were analyzed. Mean baseline TTC for the group was 20.36 min. With cognitive distraction and external stress mean TTC decreased to 17.87 min. Mean baseline ALI score for the group was 3.32 errors per anastomosis. The introduction of cognitive distraction and external stress increased the mean to 4.86 errors per anastomosis. Total errors per anastomosis increased from 91 errors at baseline to 137 errors with cognitive distraction and external stress. Under stress, participants were more efficient but had reduced anastomotic accuracy. Conclusion: Under stress, surgeons were more efficient, this translated into faster completion of a microsurgical anastomosis. Efficiency, however, came at the expense of accuracy.
RESUMEN
Advancements and increased availability of radiological services have revolutionised our approach to oncological and reconstructive surgical practice. With an increasing demand for accuracy in diagnosis and improved oncological outcome, the requirement for precise application of radiological tools and the exploration of novel software has developed. This has led to the evaluation of modern technologies such as computer-aided design to enhance reconstructive surgery. Mandibular reconstruction following oncological resection using an osteocutaneous fibular free flap is now considered to be the gold standard reconstructive surgical approach, as this approach provides more satisfactory outcomes for both patients and reconstructive surgeons. Recent years have seen Irish reconstructive surgeons introduce computer-aided design pre-operative planning to operating theatres as means of improving cosmetic, functional and oncological outcome, yet the detailed, complex planning required pre-operatively is not well described. Herein, the purpose of this article was to demonstrate the precision and accuracy of virtual surgical planning computer-aided design (VSP-CAD) as a modern surgical approach to craniofacial reconstruction following surgical resection of an American Joint Committee on Cancer stage 4 oral carcinoma.
RESUMEN
Deliberate injection of hydrocarbon remains an uncommon method of self harm. There is a paucity of information pertaining to soft tissue toxicity throughout the literature. Prompt recognition of the potential ramifications is needed to try salvage limb function. Hydrocarbon toxicity can result in multi organ failure. This case report demonstrates the recommended diagnostic approach, work up and treatment involved in such a case. A 26 year old male deliberately injected petrol into the anterior compartment of his non dominant forearm in a suicide attempt. Multidisciplinary involvement from surgeons, psychiatrists and hand therapists was needed to maximize functional outcome. He avoided systemic toxicity but required an urgent fasciotomy. He required significant follow up with hand therapy to regain usage of the limb. However his long term outcomes were poor with a power grading 3/5 in the anterior compartment muscles.

We report a rare case that highlights acute pancreatitis as the protagonist of Fournier's Gangrene. This patient was treated with a radical debridement of his perineum at presentation and subsequently reconstructed with split thickness skin grafting. This is an unusual aetiology of necrotizing fasciitis with only one other case reported in the literature. This serves to emphasize to physicians that acute pancreatitis is a potential source when investigating and treating patients with Fournier's Gangrene.
RESUMEN
BACKGROUND: Distinguishing Spitz naevi from malignant melanoma can pose diagnostic dilemmas and atypical subtypes present particular challenges to both clinicians and pathologists. OBJECTIVES: We aimed to review our institutional experience of Spitz naevi, to characterise demographics and analyse the clinical and histological features associated with difficult/equivocal diagnosis of such lesions. Additionally we evaluated discordant cases following expert opinion at a second institution. MATERIALS & METHODS: Data was retrospectively analysed on all cases of Spitz naevi treated over an 18-year period (1991-2009). Equivocal cases, (where a diagnosis of classical Spitz naevi could not be confidently made) were identified. The original/provisional diagnosis and second histopathological opinions were compared. RESULTS: 148 cases were identified 112 lesions were classical Spitz naevi. 36 lesions (24.3%) posed diagnostic difficulty (equivocal cases). These equivocal cases tended to occur in the lower limbs, have brown pigmentation, be smaller in size (<6mm) and occur in older (>24 years) patients. Clinical sub-types and gender were not associated with equivocal cases. Of the 36 equivocal cases, the second opinion in 23 cases (63.9%) concurred with the original diagnosis. Of the remaining 13 cases (discordant cases), 10 cases that were originally deemed malignant were reported as benign after the second opinion. Two benign lesions were reclassified as malignant. CONCLUSION: A firm histological diagnosis of Spitz naevi cannot be made with certainty in nearly a quarter of cases. Thus, additional external analysis for a second opinion should be sought for these equivocal cases.

BACKGROUND: Melanoma in situ (MIS) accounts for up to 27% of all melanomas. MIS has no metastatic potential and the aim should be to excise the lesion completely with a clear histological margin, although margin clearance remains undefined. We aimed to assess the relation of histological excision margins of MIS to recurrence and progression to invasive disease. METHODS: We analyzed all patients with MIS excised by wide local excision or staged excision in our institution over a 5-year period from December 2008 to January 2014 using a prospectively maintained database. Clinicopathologic details included patient demographics, anatomical site of lesion, melanoma subtype, histological excision margin, and recurrence. RESULTS: A total of 410 patients had MIS excised during this time, the majority of which were lentigo maligna subtype (79%). The average histological excision margin was 3.7 mm. The rate of recurrence was 2.2% (9/410), with a median follow-up of 23 months. Lentigo maligna had a similar rate of recurrence to non-lentigo MIS (2.3% vs 1.2%) (P = 0.69). The mean excision margin of those that recurred was 1.9 mm compared with an average of 3.8 mm in those that did not. The rate of recurrence of MIS with histological excision margin ≤3.00 mm was 3.8% compared with 0.5% in those with a histological margin >3.00 mm (P = 0.03). One case of MIS recurred as invasive disease. CONCLUSION: At institutions using wide local excision or staged excision for MIS, a histological margin of >3.0 mm is required to achieve a low recurrence rate.
RESUMEN
BACKGROUND: There has been substantial rise in the volume of published works on fat transfer in the medical literature in the past 25 years, and this is indicative of its growing popularity. However, many unanswered questions remain, and there is no consensus as to the optimum technique. Consequently, the scientific and clinical research on fat grafting continues to increase rapidly. The purpose of our study was to perform a bibliometric analysis of the most-cited articles in fat transfer. METHODS: Through the Web of Science, all articles relating to fat grafting were identified in the plastic and reconstructive literature. The 100 most-cited articles were identified and analyzed individually. RESULTS: Total citations ranged from 35 to 363 and the most-cited paper by Sidney Coleman was published in Plastic and Reconstructive Surgery. The United States produced 46% of the most-cited papers, and the University of California was the most prolific institution. Twenty-one articles focused on lipofilling to the face while 14 articles looked at fat grafting to the breast. CONCLUSIONS: The scientific relevance of a published work is reflected in the number of citations from peers that it receives. Therefore, the 100 most-cited papers in fat grafting have been the most influential articles on this field, and they are likely to be the ones that are remembered most.
RESUMEN
INTRODUCTION: Bilateral breast reduction (BBR) is one of the most frequently performed female breast operations. Despite no evidence supporting efficacy of drain usage in BBRs, postoperative insertion is common. Recent high quality evidence demonstrating potential harm from drain use has subsequently challenged this traditional practice. The aim of this study is to assess the current practice patterns of drains usage by Plastic & Reconstructive and Breast Surgeons in UK and Ireland performing BBRs. METHOD: An 18 question survey was created evaluating various aspects of BBR practice. UK and Irish Plastic & Reconstructive and Breast Surgeons were invited to participate by an email containing a link to a web-based survey. Statistical analysis was performed with student t-test and chi-square test. RESULTS: Two hundred and eleven responding surgeons were analysed, including 80.1% (171/211) Plastic Surgeons and 18.9% (40/211) Breast Surgeons. Of the responding surgeons, 71.6% (151/211) routinely inserted postoperative drains, for a mean of 1.32 days. Drains were used significantly less by surgeons performing ≥20 BBRs (p = 0.02). With the majority of BBRs performed as an inpatient procedure, there was a trend towards less drain usage in surgeons performing this procedure as an outpatient; however, this was not statistically significant (p = 0.07). CONCLUSION: Even with the high level of evidence demonstrating the safety of BBR without drains, they are still routinely utilised. In an era of evidence- based medicine, surgeons performing breast reductions must adopt the results from scientific research into their clinical practice.

Metastatic cutaneous Crohn's disease is a rare entity first described by McCallum et al. in 1976. It is diagnosed when histologically characteristic granulomata are seen at a site not contiguous with inflammatory disease in the gastrointestinal tract. We herein report presentation, diagnosis and management of a 28 year old lady with disabling, symptomatic cutaneous Crohn's of the buttocks and natal cleft refractory to Infliximab therapy. To the best of our knowledge only four other adult cases have been reported in the literature of metastatic cutaneous Crohn's disease of the buttock area distant from a flexure or area of skin apposition. The differential diagnosis in this case was Hidradenitis Suppurativa. A good cosmetic result and excellent symptom control were achieved with extensive debridement, wide local excision, vacuum assisted closure and delayed skin grafting.

Reconstruction after resection of a large oropharyngeal tumour poses a difficult challenge. This case illustrates an extension of the previously described facial artery musculomucosal (FAMM) flap, whereby a defect of the soft palate is replaced with a similar trilaminar structure in the form of irradiated, redundant lower lip. This allows not only the treatment of the palatal defect, but also management of dribbling secondary to a marginal mandibular palsy.

Transplantation of islets into the portal vein of diabetic patients has emerged as a promising procedure for the treatment of type 1 diabetes. However, shortages of donors and adverse effects leading to graft impairment and/or rejection have prevented this procedure from achieving widespread clinical application. The aim of this study was to develop a method that could support the survival and function of transplanted islets using a prevascularized tissue engineering chamber. Islets were transplanted into tissue engineering chambers established on the epigastric pedicle in the groin of diabetic mice. Islets were transplanted at the time of chamber implantation or with 21 days prevascularization of the chamber. Transplantation of islets into prevascularized chambers into diabetic RIP-K(b) mice resulted in a significant reduction in blood glucose levels that became evident in the third week and improved glycemic control as measured by a glucose tolerance test. This study highlights that islet survival and function are potentiated by allowing a period of prevascularization within tissue engineering chambers before islet transplantation. This novel prevascularized chamber may be an improved method of islet transplantation. It can be easily accessed for islet seeding, easily retrieved, and transplanted to alternative anatomical sites by microvascular methods.
