Objective: Subsurface bacterial burden can be missed during standard wound examination protocols. The real-time bacterial fluorescence imaging device, MolecuLight i:X, visualises the presence of potentially harmful levels of bacteria through endogenous autofluorescence, without the need for contrast agents or contact with the patient. The intended use of the imaging device is to assist with the management of patients with wounds by enabling real-time visualisation of potentially harmful bacteria. The aim of this study was to establish the accuracy of the wound imaging device at detecting pathogenic bacteria in wounds. Methods: A single-centre, prospective observational study was conducted in Cork University Hospital in an outpatient plastic surgery wound care clinic. Patients had their wounds photographed under white and autofluorescent light with the imaging device. Auto-fluorescent images were compared with the microbiological swab results. Results: A total of 33 patients and 43 swabs were included, of which 95.3% (n=41) were positive for bacteria growth. Staphylococcus aureus was the most common bacterial species identified. The imaging device had a sensitivity of 100% and specificity of 78% at identifying pathological bacteria presence in wounds on fluorescent light imaging. The positive predictive value (PPV) was 95.4%. The negative predictive value (NPV) was 100%. It demonstrated a sensitivity and specificity of 100% at detecting the presence of Pseudomonas spp. Conclusion: The imaging device used could be a safe, effective, accurate and easy-to-use autofluorescent device to improve the assessment of wounds in the outpatient clinic setting. In conjunction with best clinical practice, the device can be used to guide clinicians use of antibiotics and specialised dressings.
Hand surgery research has mirrored trends seen in other surgical specialties, with a significant increase in quality of evidence over time. Yet, high-quality evidence still remains infrequent.
This study identified outcomes as good as if not superior to international averages with preservation of satisfaction with breast and psychosocial well-being. Breast Q could help form a template for national benchmarks in patients undergoing mastectomy and reconstruction.
Introduction COVID19 pandemic poses a global threat, with many unknowns. The potential for resource limited countries to suffer huge mortality is of major concern. Prevention and risk reduction strategies are paramount in the current absence of effective treatment or a vaccine. There is a global shortage of personal protective equipment. Aims This short paper describes the rationale for and development of a cloth homemade mask and has a step by step video. Results The template is reproducible around the world and is both washable and cheap. Conclusion This article describes a simple way to make a cloth mask, suitable if medical masks are not available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
