Epidemiology And Outcomes Of Radiator Burns At A High Throughput Burns Centre.

Indoor radiator burns can cause significant morbidity and mortality, especially in vulnerable patients. However, the epidemiology and clinical outcomes are poorly characterized. A retrospective study of all radiator burns referred to a tertiary regional burns centre between 2013-2019 was conducted. Four hundred and forty-seven patients (median age 25.6 years, male:female ratio 1.4:1) were referred; 109 (24%) admitted, 201 (45%) managed in outpatients and 137 (31%) managed locally. The incidence of burns leading to referral was 0.65/100,000/year, but increased annually. Contact burns consisted of 99.6%. Age distribution was bimodal: <5 years (43%), >65 years (27%), although all ages were affected. Median TBSA was 0.75% (0.1-11.5%), but 79% had injuries <2%. Childhood burns were predominantly superficial dermal grab injuries, usually manageable as outpatients. Elderly patients had larger burns usually secondary to falls or impaired sensorium, and were more likely to die (p<0.05). Burns due to impaired sensorium were deeper and more likely to require surgery (p<0.05). Sixty-three (14%) patients required surgery. Thirty-day mortality was 1.1%. Age was the only significant predictor of mortality. This study quantifies the epidemiology and outcomes of a growing problem. It identifies at risk populations (extremes of age), and important features of the clinical assessment.

Les brûlures en milieu clos liées à un radiateur peuvent être responsables de morbidités et de mortalité non négligeables, particulièrement chez les patients fragiles. Toutefois, l'épidémiologie et l'évolution en sont mal connues. Nous avons étudié rétrospectivement les 447 brûlures (âge médian des patients 25,6 ans ; 1,4 hommes pour 1 femme) liées à ces appareils adressées dans un CTB de référence entre 2013 et 2019. Parmi celles- ci, 109 (24%) ont été hospitalisées, 201 suivies par nous en externe et 137 (31%) pris en charge dans une structure non spécialisée. L'incidence annuelle est de 0,65/100 000/an, en augmentation régulière. Quasiment toutes (99,6%) sont dues à un contact. Bien que tous les âges puissent être affectés, on observe 2 pics d'incidence, avant 5 ans (43% des patients) et après 65 ans (27%). La surface atteinte s'étendait de 0,1 à 11,5% (médiane 0,75%), 79% des brûlures touchant moins de 2% SCT. Les enfants souffraient le plus souvent de brûlures superficielles, suivies en externe, après avoir empoigné le matériel. Chez les sujets âgés, les brûlures, consécutives à une chute ou à contact prolongé en raison de troubles sensoriels (ces dernières plus souvent profondes et nécessitant un traitement chirurgical ­ p< 0,05), sont plus étendues et plus souvent mortelles (p< 0,05). Soixante- trois (14%) patients ont eu besoin de chirurgie, la mortalité à 30 jours était de 1,1% ; l'âge étant le seul facteur prédictif de mortalité. Cette étude précise l'épidémiologie et l'évolution d'un problème émergeant, la population à risque (âges extrêmes) et met en avant certaines particularités cliniques.

St Andrew's COVID-19 surgery safety study: hand trauma.

INTRODUCTION: Adaptation is vital to ensure successful healthcare recovery during the COVID-19 pandemic. Hand trauma represents the most common acute emergency department presentation internationally. This study prospectively evaluates the COVID-19 related patient risk, when undergoing management within one of the largest specialist tertiary referral centres in Europe, which rapidly implemented national COVID-19 safety guidelines. MATERIALS AND METHODS: A prospective cohort study was undertaken in all patients referred to the integrated hand trauma service, during the UK COVID-19 pandemic peak (April-May 2020); all were evaluated for 30-day COVID-19 related death. Random selection was undertaken for patients with hand trauma who either underwent non-operative (control group) or operative (surgery group) management; these groups were prospectively followed-up within a controlled cohort study design and telephoned at 30 days following first intervention (control group) or postoperatively (surgery group). RESULTS: Of 731 referred patients (566 operations), there were no COVID-19 related deaths. Both groups were matched for sex, age, ethnicity, body mass index, comorbidities, smoking, preoperative/first assessment COVID-19 symptoms, pre- and postoperative/first assessment isolation and positive COVID-19 contact (p > 0.050). There were no differences in high service satisfaction (10/10 compared with 10/10; p = 0.067) and treatment outcome (10/10 compared with 10/10; p = 0.961) scores, postoperative/first assessment symptoms (1%, 1/100 compared with 0.8%, 2/250; p = 1.000) or proportion of positive tests (7.1%, 1/14 compared with 2.2%, 2/92; p = 0.349), between the control (n = 100) and surgery (n = 250) groups. CONCLUSION: These data support continued and safe service provision and no increased risk to patients who require surgical management. Such findings are vital for healthcare providers when considering service adaptations to reinstate patient treatment.

St Andrew's COVID-19 Surgery Safety (StACS) study: Skin cancer.

BACKGROUND: Skin cancer represents the most common malignancy worldwide and it is imperative that we develop strategies to ensure safe and sustained delivery of cancer care which are resilient to the ongoing impact of COVID-19. OBJECTIVE: This study prospectively evaluates the COVID-19 related patient risk and skin cancer management at a single tertiary referral centre, which rapidly implemented national COVID-19 safety guidelines. METHOD: A prospective cohort study was performed in all patients who underwent surgery for elective skin cancer service management, during the UK COVID-19 pandemic peak (April-May 2020). 'Real-time' 30-day hospital database deceased data were collected. Random selection was undertaken for patients who either underwent operative (surgery group) management or remained on the waiting list (control group); these groups were also prospectively followed-up within a controlled cohort study design and telephoned at the end of June 2020 for the control group or 30 days post-operatively. RESULTS: Of the 767 patients who had operations, there were no COVID-19 related deaths. Both the surgery (n = 384) and control (n = 100) groups were matched for age, sex, ethnicity, BMI, presence of comorbidities, smoking and positive COVID-19 contact. There were no differences in post-operative versus any symptom development (1.3%, 5/384 vs. 4%, 4/100, p = 0.093), or proportion of positive tests (8.6%, 33/384 vs. 8%, 8/100; p = 0.849), between the surgery and control groups. CONCLUSION: These data support continued and safe service provision, and no increased risk to skin cancer patients who require surgical management, which is vital for continuation of cancer treatment in the context of a pandemic. LEVEL OF EVIDENCE: II.

St Andrew's COVID-19 surgery safety (StACS) study: The Burns Centre experience.

BACKGROUND: The COVID-19 pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has the potential to significantly impact burns patients both directly through infective complications of an immunocompromised cohort, and indirectly through disruption of care pathways and resource limitations. The pandemic presents new challenges that must be overcome to maintain patient safety; in particular, the potential increased risks of surgical intervention, anaesthesia and ventilation. This study comprehensively reviews the measures implemented to adapt referral pathways and mitigate the risk posed by COVID-19 during the height of the pandemic, within a large Burns Centre. METHODS: A prospective cohort study was designed to assess patients treated at the Burns Centre during the UK COVID-19 pandemic peak (April-May 2020), following implementation of new safety measures. All patients were analysed for 30-day mortality. In addition, a prospective controlled cohort study was undertaken on all inpatients and a random sample of outpatients with telephone follow-up at 30 days. These patients were divided into three groups (operative inpatients, non-operative inpatients, outpatients). COVID-19 related data collected included test results, contact with proven cases, isolation status and symptoms. The implemented departmental service COVID-19 safety adaptations are described. RESULTS: Of 323 patients treated at the Burns Centre during the study period, no 30-day COVID-19 related deaths occurred (0/323). Of the 80 patients analysed in the prospective controlled cohort section of the study, 51 underwent COVID-19 testing, 3.9% (2/51) were positive. Both cases were in the operative group, however in comparison to the non-operative and outpatient groups, there was no significant increase in COVID-19 incidence in operative patients. CONCLUSIONS: We found no COVID-19 related mortality during the study period. With appropriate precautions, burns patients were not exposed to an increased COVID-19 risk. Similarly, burns patients undergoing operative management were not at a significantly increased risk of contracting COVID-19 in comparison to non-operative groups.

A systematic review of outcomes following hand reconstruction using flaps from the superficial palmar branch of the radial artery (SUPBRA) system.

BACKGROUND: Flaps based on the superficial branch of the radial artery (SUPBRA) are indicated when homo- or heterodigital flaps are inappropriate, but glabrous or like-for-like reconstruction is required. AIM: To systematically review the outcomes of hand reconstruction using SUPBRA flaps. METHODS: PubMed was searched for English-language articles studying SUPBRA flaps in November 2019. Data collected included flap vascular supply, dimensions, complications, donor site closure, and two-point discrimination. RESULTS: Twenty-six papers were eligible (410 flaps). Flaps were classified as glabrous, nonglabrous or combined. Nonglabrous flaps were either free- (52%) or reverse-flow pedicled (1.7%) wrist flaps. Glabrous flaps were either free palmar (36.3%), reverse-flow pedicled palmar (2%), antegrade-flow pedicled palmar (0.2%) or perforator-based island palmar flaps (3.7%). Combined glabrous/nonglabrous flaps formed 4.1% of flaps. Maximal flap dimensions allowing direct closure were: 3.1 × 6 cm for wrist flaps and <3 × 10 cm for glabrous palmar flaps. Combined flaps can be 10 × 16 cm. Overall, complete and partial flap failure rates were 3.17% and 0.98%, respectively. Most complete failures were due to venous thrombosis. All 220 wrist donor sites were closed directly. Two out of 173 palmar donor sites (≥3.1) could not be primarily closed. Wound complications were rare, but 53.4% of free palmar flaps required debulking. The results of neurorrhaphy were inconsistent. CONCLUSIONS: Flaps based on the SUPBRA are robust, provide like-for-like reconstruction of glabrous skin defects in one-stage, offer versatility due to diverse skin paddle orientation patterns and are in the same operative field as the defect.

St Andrew's COVID-19 surgery safety (StACS) study: Elective plastic surgery, trauma & burns.

INTRODUCTION: This study evaluates COVID-19 related patient risk, when undergoing management within one of the largest specialist centres in Europe, which rapidly implemented national COVID-19 safety guidelines. METHOD: A prospective cohort study was undertaken in all patients who underwent surgical (n = 1429) or non-operative (n = 191) management during the UK COVID-19 pandemic peak (April-May 2020); all were evaluated for 30-day COVID-19 related death. A representative sample of elective/trauma/burns patients (surgery group, n = 729) were selected and also sub-analysed within a controlled cohort study design. Comparison was made to a random selection of non-operatively managed (non-operative group, n = 100) or waiting list (control group, n = 250) patients. These groups were prospectively followed-up and telephoned from the end of June (control group) or at 30 days post-first assessment (non-operative group)/post-operatively (surgery group). RESULTS: Complex general (9.2%, 136/1483) or regional (5.0%, 74/1483) anaesthesia cases represented 14.2% (210/1483) of operations undertaken. There were no 30-day post-operative (0/1429)/first assessment (0/191) COVID-19 related deaths. Neither the three sub-speciality plastic surgery, or non-operative groups, displayed increases in post-operative/first assessment symptoms in comparison to each other, or to control. The proportion of COVID-19 positive tests were: 7.1% (1/14) (non-operative), 5.9% (2/34) (burns) and 3.0% (3/99) (trauma); there were however no significant differences between these groups, the elective (0%, 0/54) and control (0%, 0/24) groups (p = 0.236). CONCLUSION: We demonstrate that even heterogeneous sub-speciality patient groups, who required operative/non-operative management, did not incur an increased COVID-19 risk compared to each other or to control. These highly encouraging results were achieved with described, rapidly implemented service changes that were tailored to protect each patient group and staff.

The mini-temporalis turnover flap for midface reanimation: Photogrammetric and patient-rated outcomes.

BACKGROUND: Mini-temporalis transposition (MTT) flaps, modified from Gillies' technique, have become less popular than temporalis tendon transfers for midface reanimation. MTT involves raising the middle third of the temporalis, transposition over the zygomatic arch and lengthening with deep temporalis fascia which is sutured to the orbicularis oris. AIM: This retrospective study assessed subjective and objective outcomes following MTTs by a single surgeon from 2009 to 2019. METHODS: Operative and surgical details were recorded. Four blinded consultants rated pre- and postoperative videos according to Terzis' scale. Pre- and postoperative resting, Mona Lisa and canine smile photographs were analysed using Emotrics, the software that automatically computes differences in inter-landmark distances. Patients also completed the Glasgow Benefit Inventory (GBI) patient-rated outcome measure. RESULTS: Forty-one patients (mean age 65.8 ±â€¯15.5) underwent MTT, median 3 (0.4-57) years post-paralysis and were followed up for median of 2.2 (0.4-8.8) years. Higher mean postoperative Terzis score demonstrates symmetric and aesthetic improvements (3 ±â€¯1.3 vs. 2 ±â€¯1; p<0.05). Emotrics analysis showed postoperative improvements in resting and dynamic symmetry of all indices, with the majority statistically significant (p<0.003). The mean GBI was 35.19 with 17 (94.4%) patients reporting improvement, whereas one (5.6%) patient reported detriment after surgery. Two (5.4%) patients suffered complications: one haematoma and one infection. Four patients (9.8%) required revisional flap tightening. No patients requested revisional surgery for temporal hollowing or zygomatic fullness. CONCLUSIONS: MTT effectively improves both subjective and objective resting and dynamic midface symmetry in a single stage. These results suggest this technique is a good alternative to temporalis tendon transfer techniques.

Ventilatory practices in extremely low birth weight infants in a level III neonatal intensive care unit.

INTRODUCTION: Although non-invasive forms of ventilation have recently spread in neonatology, invasive ventilation still plays a key role in the support of extremely low birth weight (ELBW) infants. The purpose of this study was to assess changes in neonatal ventilation practices for ELBW infants and compare outcomes between two epochs (2005-2009 vs. 2010-2015) to analyze progression stemming from the implementation of newer clinical guidelines. MATERIALS AND METHODS: We conducted a retrospective study with data collection from all ELBW infants born between 2005 and 2015 in our center through their individual clinical records. The main outcome was the prevalence of bronchopulmonary dysplasia (BPD) in both periods. Assessment of other morbidities and survival were secondary outcomes. RESULTS: A hundred and thirty-one infants were included; median gestational age of 27 weeks (23-33) and mean birth weight of 794.58g (±149.37). Invasive mechanical ventilation (IMV) was performed on 103 (78.6%) infants. Non-significant increases in the use of non-invasive mechanical ventilation (NIMV) were observed between epochs both exclusively and following IMV. In conventional ventilation there were significant variations between epochs, namely a decrease in synchronized intermittent mandatory ventilation (SIMV) and a major growth in the addition of volume guarantee (VG). Significant decreases in BPD (from 50.9% to 32.0%) and cystic periventricular leukomalacia (cPVL) (from 27.5% to 10.7%) were observed between epochs, with no major changes in other morbidities and survival. CONCLUSION: Changes in our neonatal intensive care unit's ventilatory practices according to the most up-to-date guidelines, have led to a decrease in BPD and cPVL, over an 11-year period.

Single dose versus multiple dose of antibiotic prophylaxis in caesarean section: a systematic review and meta-analysis.

BACKGROUND: Prophylactic antibiotics are traditionally given as a single dose for caesarean section. However, inconsistent application of recommendations and recent evidence prompted a literature review. OBJECTIVES: To assess the optimal regimen for antibiotic prophylaxis in caesarean section by comparing single versus multiple doses of the same intervention. SEARCH STRATEGY: MEDLINE, Web of Knowledge, SCOPUS, CENTRAL and ongoing trials databases were searched. Reference lists were reviewed and international groups contacted. SELECTION CRITERIA: Randomised controlled trials (RCT) comparing single with multiple dose regimens of the same antibiotic prophylaxis. Quasi-RCT and abstracts were suitable for inclusion. DATA COLLECTION AND ANALYSIS: Reviewers independently extracted data and assessed quality of evidence. A random-effects model was used and results presented as risk ratio (RR) with 95% confidence intervals (CI). MAIN RESULTS: Sixteen studies were included, involving 2695 women. Nonsignificant differences were observed between single dose and multiple dose antibiotic prophylaxis in the incidence of postpartum infectious morbidity (RR 0.95, 95% CI 0.75-1.20, I2 = 25%), endometritis (RR 1.03, 95% CI 0.74-1.42, I2 = 0%) and wound infection (RR 1.22, 95% CI 0.72-2.08, I2 = 0%). A trend towards lower risk of urinary tract infection was seen with multiple dose (RR 0.65, 95% CI 0.34-1.24, I2 = 0%). CONCLUSIONS: There was insufficient evidence to determine whether there is a difference between single and multiple dose regimens in reducing the incidence of infectious morbidity after caesarean section. The quality of evidence was very low and well-designed RCTs are needed. TWEETABLE ABSTRACT: Insufficient evidence of difference between dosage regimens of antibiotic prophylaxis in caesarean section.
