RESUMO
Background: Merkel cell carcinoma (MCC) is a rare cutaneous malignancy with high metastatic potential. Sentinel lymph node biopsy (SLNB) is used to assess locoregional spread, facilitate staging, and inform prognosis. Positive nodal status is associated with higher recurrence rates and reduced overall survival. Methods: A systematic search was conducted. Eligible articles included patients diagnosed with MCC, who would be candidates for or who had SLNB. The Covidence tool was used for screening and data extraction, including additional treatments, disease-free survival, overall survival, and recurrence. Methodological quality was assessed using the Newcastle-Ottowa Scale criteria. Results: SLNB was associated with increased likelihood of completion lymphadenectomy (223 versus 41), regional radiotherapy (2167 versus 808), and systemic chemotherapy (138 versus 31). Overall survival for patients undergoing SLNB was 81% at 2 years, 75% at 3 years, and 72% at 5 years (odds ratio: 0.79). Hazard ratio for positive SLNB versus negative was 3.36 (P < 0.001). Five-year disease recurrence was 23.3% in patients undergoing SLNB. Conclusions: Lymph node metastases are associated with reduced overall survival and increased recurrence of MCC. Determining nodal status early can inform prognosis, facilitate staging, and determine need for adjuvant treatment. Adjuvant treatments are associated with reduced mortality and improved overall survival; SLNB is an important influencer of their use. Early prophylactic intervention should be considered in MCC in both positive and negative nodal status to improve overall outcomes. Widespread use of SLNB will allow more accurate assessment of the role of nodal status on adjuvant treatment and long-term outcomes.
RESUMO
BACKGROUND: The use of sentinel lymph node biopsy (SLNB) in the older population, defined as those over 70 years old, has been debated since the adoption of SLNB into routine practice. Interestingly, there remains a paucity of evidence, especially regarding the rates of SLNB positivity, complications, and subsequent adjuvant therapy in those with node positivity. METHOD: Data on patient's comorbidities, positivity rates, complication rates, and subsequent adjuvant treatments were collected prospectively from 998 patients (644 patients < 70 and 354 patients ≥ 70 years old) between 2016 and 2022. RESULTS: Patients aged ≥ 70 were found to have a higher prevalence of comorbidities, including hypertension, diabetes and hyperlipidaemia. The mean Breslow thickness was 2.2 and 2.5 in the under and over 70 groups respectively (p = 0.03). The mean mitotic rate was found to be 3.3 in the under 70 s and 4.1 in the over 70 s (p = 0.02). Despite these results, no significant differences were observed in the positivity rates of sentinel lymph node biopsies or in the treatment options selected for positive results. The under 70 s were more likely to experience loss of sensation (p < 0.01), but no difference was found in the total number of complications between the two groups. CONCLUSION: Although patients aged 70 and above had a greater incidence of comorbidities, the study revealed that they had lower complications rates and there was no significant variation in the SLNB positivity rate or chosen treatment options between the two age groups. This study supports the move to physiological rather than chronological age assessments in SLNB of the elderly.

INTRODUCTION: This study aimed to identify the spectrum of desquamating skin diseases referred for tertiary burns care and quantify the care requirements and expenses associated with caring for these patients within the burns service. METHODS: Patient records were identified with nonburn-induced skin loss between 2016 and 2022. Data was extracted from inpatient records, operative notes, and dressing clinic records. A cost analysis was conducted using figures from the National Schedule of National Health Service Costs and our own unit-specific costs. RESULTS: Twenty patients were identified, with a median age of 46.5 and a median total body surface area of 30%. The mean length of stay was 21.2 days, with 8/20 patients requiring intensive care. Overall mortality was 30%, rising to 50% if patients required intensive treatment unit (ITU) admission. Patients had a mean of 1.5 procedures under general anaesthesia and a mean operative time of 169 min per patient. Postoperatively, a mean of 8.3 dressing changes was required per patient (range 1-21). Of 75% of patients referred as suspected toxic epidermal necrolysis syndrome (TENS), only 32% of patients histologically had TENS (32%), with linear IgA disease, pemphigus vulgaris and bullous lupus comprising the other diagnoses. Cost analysis predicted a total cost to the unit of £1,422,106. CONCLUSION: Desquamating dermatological diseases are life-threatening conditions with exhaustive care requirements. Our experiences highlight the importance of awareness of the range of desquamating skin conditions beyond TENS to enable optimum management and the need to ensure adequate financial provisions to accommodate the care requirements mandated by these patients.

In recent years, there has been an increasing interest in the practical applications of virtual reality (VR) in healthcare. One discussed application of this technology is to reduce anxiety during procedures for paediatric patients. Following skin loss in paediatric patients, careful management of the wound with appropriate dressings and frequent dressing changes is a key part of the treatment process. In children, continued dressing changes are often a source of anxiety, which complicates procedures causing distress to the child, their parents and staff members. VR systems have the potential to not only reduce anxiety but also pain in children requiring frequent dressing changes. Although our knowledge of this technology is improving, further research is needed to evaluate its full potential in this population and to establish guidelines to take advantage of the full potential of VR technology.

BACKGROUND: Circumferential deep burns on the limb lead to a constrictive, tourniquet-like effect causing critical limb ischaemia. The treatment, escharotomy, is a time-critical procedure that sometimes is required before the patient arrives at a burn centre. At present, no practical method of teaching this procedure is incorporated into formal educational courses. METHODS: The feasibility of a comprehensive education package to teach upper limb escharotomy was assessed in a group of plastic and general surgery trainees in Wales. Small group workshops focused on the clinical presentation of patients requiring escharotomy. Participants then executed this on a custom-made high-fidelity simulation upper limb model. The articulated limb has subcutaneous silicone fat which bulges upon decompression and a finger-tip which turns pink indicating satisfactory reperfusion. A before and after five-point Likert scale was used to evaluate changes in participants' self-assessed confidence in the surgical management of escharotomy. Statistical significance between scores was assessed using the Wilcoxon signed-rank test. RESULTS: A total of 34 participants took part. Following completion of the course, general surgery trainees' confidence in executing the procedure increased from a median score of 1.00 "not confident at all" (IQR 1.00-2.00) to 4.00 "fairly confident" (IQR 4.00-5.00, p < 0.01). Plastic surgery trainees' confidence increased from a median score of was 3.00 "somewhat confident" (IQR 1.75-4.00) to 4.00 "fairly confident" (IQR 3.00-4.25, p < 0.01). DISCUSSION: We developed a comprehensive simulator course that has been demonstrated to improve candidate's confidence in performing escharotomy. The next stage in the course development is to confirm the results in a larger cohort. By developing this simulator course we aim to improve emergency burn care education in the UK and globally.

The aim of this article is to provide an overview on paediatric facial paralysis, looking into aetiology, epidemiology, assessment and investigation and subsequent treatment options available. Facial paralysis describes the inability to activate the muscles of fascial expression. Overall, it affects 2.7 per 100 000 children under 10 years old and 10.1 per 100 000 children over 10 years old each year. There are many causes of facial paralysis and the outcomes and necessary treatments vary depending on the cause. The mainstays of medical management are corticosteroids and facial therapy; however, when the facial palsy persists, facial deformity surgery is an option to improve the facial symmetry, protect vision and recreate dynamic movement.

BACKGROUND: Increasingly radical surgery combined with neo-adjuvant radiotherapy present a challenge for the reconstructive surgeon. The study objective was to review outcomes of Vertical Rectus Abdominis Myocutaneous (VRAM) flap-based perineal reconstruction following resectional surgery for pelvic malignancies. METHODS: Single-centre retrospective analysis of patients undergoing immediate VRAM flap reconstruction of a perineal/pelvic defect for pelvic malignancy between July 2009 and November 2017. Primary outcome was perineal morbidity (surgical site infection (SSI), flap loss or dehiscence and perineal hernia). Secondary outcomes were length of stay and donor site morbidity (SSI, full-thickness dehiscence and incisional hernia). RESULTS: A total of 178 patients (96 females) were included. Median age was 67 years (range 28-88). The majority were performed for locally advanced rectal adenocarcinoma (n = 122; 68.5%) and 136 (76.4%) patients had received neoadjuvant radiotherapy. Four patients had complete flap loss (2.3%), and 40 had perineal dehiscence (22.5%); however, only, 18 patients required a return to theatre during the admission for perineal-related complications (10.1%). Abdominal dehiscence occurred in six patients (3.4%). Median length of post-operative stay was 15 days (6-131). Sixty-day mortality rate was 1.1%. SSI at the midline and perineum occurred in 34 (19.1%) and 38 patients (21.3%), respectively. At 90-day post-operatively, 75.6% of perineal wounds were healed. During a median follow-up of 44.5 months, twelve, eleven and 39 patients were diagnosed with perineal, midline and parastomal hernias, respectively (6.9%, 6.2% and 21.9%). CONCLUSIONS: It is important to have accurate knowledge of perineal and donor-site morbidity rates to allow an informed consent process.

Metabolism is a tightly regulated sequence of events, supported by key reactions between enzymes and enzyme-specific substrates. These reactions have the potential to produce metabolic side products that can have deleterious effects to further key metabolic reactions. The nicotinamide repair system consists of two partner enzymes, NAD(P)HX epimerase (NAXE) and NAD(P)HX dehydratase (NAXD). These enzymes regulate the levels of metabolic side products. Here we present a case of an 11-month old child who presented to our paediatric department with pyrexia, lethargy and multiple cutaneous lesions on the background of NAXD deficiency, a lethal neurometabolic disorder of early childhood. Despite early intervention with intravenous antibiotics, the patient failed to improve and subsequently passed away. The skin lesions were thought to be a consequence of systemic disease rather than a propagator of infection. Clinicians should be aware of this incredibly rare metabolic disease, its potential to cause widespread systemic dysfunction and the developing avenues for management.
RESUMO
Contour irregularities following pediatric craniofacial surgery are common. Hydroxyapatite cranioplasty is a successful technique for optimizing the aesthetic outcome in these patients. We describe a simple technique that can be carried out at the bedside to calculate the volume of hydroxyapatite needed and therefore optimize the preoperative planning for hydroxyapatite cranioplasty.
RESUMO
External ear abnormalities are common. These may affect ear shape, size, prominence and degree of development. They may also be associated with hearing loss. The early identification and management of hearing loss is essential. There are several options for reconstruction of the external ear using both autologous and non-autologous techniques. The aim of this article is to outline the different reconstructive options.

All animal bites have the potential to cause significant infection. In the UK, dogs are the most common source of bites. Incidence of hospital attendances attributable to dog bites has risen over the last decade. Patient groups at particular risk of bites and/or complications of infection include those at extremes of age, immunosuppressed and patients with diabetes. We report the case of a patient with diabetic peripheral neuropathy, who was admitted on two separate occasions with unprovoked bites to his toes whilst asleep, by his pet dog. He ultimately required terminalisation of the affected digits. Although unusual, this mechanism of injury has been previously described in literature. However, we are unaware of cases reporting multiple separate incidences involving the same patient and animal. We present this case to highlight the perils of untrained pet ownership in diabetic patients with peripheral neuropathy and the importance of prompt medical and surgical treatment of injuries.

Intensive care unit-acquired weakness is an evolving problem in the burn population. As patients are surviving injuries that previously would have been fatal, the focus of treatment is shifting from survival to long-term outcome. The rehabilitation of burn patients can be challenging; however, a certain subgroup of patients have worse outcomes than others. These patients may suffer from intensive care unit-acquired weakness, and their treatment, physiotherapy and expectations need to be adjusted accordingly. This study investigates the condition of intensive care unit-acquired weakness in our burn centre. We conducted a retrospective analysis of all the admissions to our burn centre between 2008 and 2012 and identified 22 patients who suffered from intensive care unit-acquired weakness. These patients were significantly younger with significantly larger burns than those without intensive care unit-acquired weakness. The known risk factors for intensive care unit-acquired weakness are commonplace in the burn population. The recovery of these patients is significantly affected by their weakness.

Keloid scars are notoriously difficult to treat with very high recurrence rates despite a range of treatment options. We present a case report of a 43-year-old man with a resistant keloid scar on his left ear from a piercing. After 15 years of multimodal treatments including surgery, steroid and 5-fluorourcil injections, the keloid persisted. It has responded very well to a single treatment of intralesional cryotherapy (trademark: CryoShape, Etgar Group International Ltd). The authors would now consider intralesional cryotherapy as a useful tool in their armamentarium for prominent, resistant or recurrent keloids. Future experience will guide its clinical applications.
