RESUMO
BACKGROUND: Absorbable or non-absorbable sutures can be used for superficial skin closure following excisional skin surgery. There is no consensus among clinicians nor high-quality evidence supporting the choice of suture. The aim of the present study was to determine current suture use and complications at 30 days after excisional skin surgery. METHODS: An international, prospective service evaluation of adults undergoing excision of skin lesions (benign and malignant) in primary and secondary care was conducted from 1 September 2020 to 15 April 2021. Routine patient data collected by UK and Australasian collaborator networks were uploaded to REDCap©. Choice of suture and risk of complications were modelled using multivariable logistic regression. RESULTS: Some 3494 patients (4066 excisions) were included; 3246 (92.9 per cent) were from the UK and Ireland. Most patients were men (1945, 55.7 per cent), Caucasian (2849, 81.5 per cent) and aged 75-84 years (965, 27.6 per cent). The most common clinical diagnosis was basal cell carcinoma (1712, 42.1 per cent). Dermatologists performed most procedures, with 1803 excisions (44.3 per cent) on 1657 patients (47.4 per cent). Most defects were closed primarily (2856, 81.9 per cent), and there was equipoise in regard to use of absorbable (2127, 57.7 per cent) or non-absorbable (1558, 42.2 per cent) sutures for superficial closure. The most common complications were surgical-site infection (103, 2.9 per cent) and delayed wound healing (77, 2.2 per cent). In multivariable analysis, use of absorbable suture type was associated with increased patient age, geographical location (UK and Ireland), and surgeon specialty (oral and maxillofacial surgery and plastic surgery), but not with complications. CONCLUSION: There was equipoise in suture use, and no association between suture type and complications. Definitive evidence from randomized trials is needed.

Skin and wound blotting are non-invasive techniques used to sample the skin and wound surface chemistry, whereby a nitrocellulose membrane is applied to an intact or broken cutaneous surface to detect biomarkers. However, there has been no comprehensive review of the evidence for the techniques used and data obtained to date. The primary aim of this study was to review the utilities of surface blotting for the diagnosis and prognosis of physiological, pre-disease, and pathological states. The secondary aim was to summarise the procedural steps. A systematic literature search was conducted on 9 July 2021 using Medline, Embase, and Google Scholar databases. Investigators used McMaster's Critical Review Form for Quantitative Studies to assess quality, then performed a narrative synthesis reporting according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twenty-five studies were reviewed. Eighteen studies were of good quality, and seven were of moderate quality. These studies conducted skin and wound blotting on 176 animals and 1546 humans. Studies reported physiological and pathological states for diagnosis and prediction of conditions, including skin tears, wound healing, biofilm detection, and skin barrier function. The four steps for blotting are surface preparation, blot preparation, application and removal of blot, and analysis. This review demonstrates that blotting can determine the skin and wound surface chemistry using a versatile and reproducible technique. However, future research is needed to validate the technique and skin biomarkers identified.

INTRODUCTION: Keloid scars are associated with physical and psychological sequelae. No studies have investigated the general public's understanding of keloids. Targeted, short educational interventions in susceptible individuals may aid understanding of the condition and compliance with treatment. We aimed to identify the population with the highest prevalence and lowest knowledge. METHODS: We surveyed four countries to determine the public's understanding of keloids. A quantitative, subjective and cross-sectional street survey was designed using the knowledge, attitudes and practice model principles. The target populations were cities in Ghana, Australia, Canada and England. Surveyors used a hybrid stratified/convenience sampling method. Primary outcomes were prevalence, exposure to keloids as an entity and overall keloid knowledge score compared across demographic groups. Study data have been made fully available for reproducibility and education (https://doi.org/10.17605/OSF.IO/3KZ5E). RESULTS: There were 402 respondents, with a median age of 32 (interquartile range 25-45.25) years, of which 193 were females. The survey was carried out between June 2015 and October 2017. The prevalence of self-identified keloids was 11% in Ghana, 6% in Australia, 2% in Canada and 7% in England. Prevalence, exposure and knowledge were higher in the Ghanaian population. CONCLUSIONS: There was association between knowledge, prevalence and the exposure to keloids as an entity. Findings may suggest targeting public health campaigns towards populations where knowledge is lowest, and exposure to and prevalence of keloids are the highest.

BACKGROUND: Delirium is an acute cerebral disorder characterised by a disturbance in cognition, attention, and awareness. Often, it's undiagnosed and associated with increased morbidity and mortality. For burn patients, the reported prevalence ranges from 16% to 39%, with a multifactorial aetiology, increasing when intensive care is required. A direct comparison of delirium between surgical specialities has not been made. AIM: 1. To audit the use of the 4AT for those who become delirious during their stay. 2. Assess the proportion of patients diagnosed with delirium during hospitalisation by surgical specialities. 3. Identification of the factors associated with delirium in surgical patients. METHODS: Investigators at a single centre conducted a two-phase study. An initial retrospective audit of delirious patients under burns, general, and orthopaedic specialities over 16months, as defined by ICD-10 coding, identified compliance screening with the 4 A's Test. This informed the design of a retrospective, observational cohort study to compare factors associated with delirium and statistical comparison between four specialities to identify delirium-associated factor, where an analysis corrects for age. RESULTS: 37% of patients with an ICD-10 code indicating delirium had a 4AT test completed. Speciality, number of operations, LOS, ICU hours, age, and discharge destination were all statistically significant independent variables. When all other variables were equal, burns had the highest predicted probability of delirium diagnosis. CONCLUSIONS: Further analysis to identify and diagnose across the specialties is required. From a patient viewpoint, their LOS, ICU hours, and operations are increased for patients coded as delirious compared to non-delirious across the specialities. On a hospital level, the mean difference in cost for a delirious compared to a non-delirious patient is AU$9317. Despite the low incidence of delirium amongst the observed specialities, burns patients were most likely to develop delirium when demographic and clinical profiles were the same, and were more likely to develop delirium at a younger age and if in ICU.

INTRODUCTION: Delirium is a potentially modifiable, acutely altered mental state, commonly characterised as a hospital-acquired complication. Studies of adult inpatients with acute burns with and without delirium identify causative risks related to the injury or treatment and outcomes related to the patient and healthcare system. We compare patients with and without delirium, providing a high-level quantitative synthesis of delirium risks and outcomes to inform guidelines and future research. METHODS: A systematic review, meta-analysis and GRADE evaluation of risks and outcomes associated with delirium in adults with acute burns was conducted using PRISMA guidelines and PROSPERO protocol CRD42021283055. The Newcastle-Ottawa Scale was used to assess quality. RESULTS: Investigators reviewed ten studies. ASA score ≥ 3, Total Body Surface Area Percentage (TBSA)> 10%, surgery done, ICU admission, hospital and also Intensive Care Unit (ICU) lengths of stay all had statistically significant associations with delirium, with low-very low certainty on GRADE evaluation. Limitations were heterogeneous studies, review methodology and study bias. CONCLUSION: Delirium represents a significant risk to comorbid patients with burns that are hospitalised, receive ICU care, and surgery. Further research is indicated to precisely categorise delirium along the clinical journey to identify modifiable factors, prevention, and proactive therapy.

INTRODUCTION: Surgical site infection (SSI) is the most common and costly complication of surgery. International guidelines recommend topical alcoholic chlorhexidine (CHX) before surgery. However, upper limb surgeons continue to use other antiseptics, citing a lack of applicable evidence, and concerns related to open wounds and tourniquets. This study aimed to evaluate the safety and effectiveness of different topical antiseptics before upper limb surgery. METHODS: This international multicentre prospective cohort study recruited consecutive adults and children who underwent surgery distal to the shoulder joint. The intervention was use of CHX or povidone-iodine (PVI) antiseptics in either aqueous or alcoholic form. The primary outcome was SSI within 90 days. Mixed-effects time-to-event models were used to estimate the risk (hazard ratio (HR)) of SSI for patients undergoing elective and emergency upper limb surgery. RESULTS: A total of 2454 patients were included. The overall risk of SSI was 3.5 per cent. For elective upper limb surgery (1018 patients), alcoholic CHX appeared to be the most effective antiseptic, reducing the risk of SSI by 70 per cent (adjusted HR 0.30, 95 per cent c.i. 0.11 to 0.84), when compared with aqueous PVI. Concerning emergency upper limb surgery (1436 patients), aqueous PVI appeared to be the least effective antiseptic for preventing SSI; however, there was uncertainty in the estimates. No adverse events were reported. CONCLUSION: The findings align with the global evidence base and international guidance, suggesting that alcoholic CHX should be used for skin antisepsis before clean (elective upper limb) surgery. For emergency (contaminated or dirty) upper limb surgery, the findings of this study were unclear and contradict the available evidence, concluding that further research is necessary.
