Evaluation of patient-reported outcome measures in burn-specific tools: A systematic review.

INTRODUCTION: Patient-reported outcome measures (PROMs) are now well-established tools to evaluate the quality of patient-centred care. Due to the multi-faceted and multi-disciplinary nature of the practice of burn care, as well as the range of significant potential sequelae, PROM's should form a fundamental component of burn quality improvement programs. We aim to 1. Explore biological, psychological, and social considerations that are currently listed in burn-specific PROM tools, as well as their efficacy, 2. Evaluate biological, psychological, and social factors that are considered in new burn-specific PROM tools or those under development, and 3. Identify any opportunities with respect to burn-specific PROM tools, in order to inform future investigation in this area. METHODS: A search was performed of MEDLINE (Ovid), EMBASE, CINAHL, and the Cochrane Library databases. Two independent reviewers screened article titles/abstracts and then the full texts using Covidence. All studies were graded independently according to the Quality Rating Scheme for Studies and Other Evidences. RESULTS: The initial search yielded 552 references. Based on ab initio inclusion and exclusion criteria, 133 full-text studies were assessed for eligibility, and 21 articles were ultimately included in the systematic review. Due to study heterogeneity, a qualitative synthesis was conducted. Existing burn-specific PROMs covered a range of biological, psychological, and social factors affecting adult and paediatric patients with burn injury, but several studies required additional PROMs for a thorough evaluation. Burn-specific PROM tools under development are poised to fill this deficit. CONCLUSION: Major burn injuries are a unique form of trauma, requiring coordinated management that considers numerous factors not relevant to other patient populations. Further research is necessary to validate existing burn-specific PROM tools and to develop more comprehensive burn-specific PROM measures that more comprehensively incorporate the bio-psycho-social model of health.

A Practical Approach to the Diagnosis and Treatment of Palmar Hyperhidrosis.

Palmar hyperhidrosis (PH), a condition characterized by excess sweating of the palms, is a common concern that presents to the plastic surgeon, which can have major impacts on patient confidence and quality of life. While several studies summarize treatment options for hyperhidrosis in general, few outline the therapeutic options available specifically for PH. Method: The authors reviewed the current literature specific to the diagnostic workup and treatment of PH. Results: In this article, we show a practical approach to managing patients presenting with PH, summarize its main nonsurgical and surgical treatment options, provide a suggested treatment ladder, and outline emerging therapeutic approaches. We suggest that, after diagnosing PH and classifying its severity, nonsurgical treatments (ie, topical antiperspirants, iontophoresis, botulinum toxin A injection, and topical/oral anticholinergics) should be utilized in a stepwise manner. In patients with severe palmar hyperhidrosis who do not respond to nonsurgical treatments, surgical intervention may be warranted, generally in the form of sympathetic denervation. Conclusion: This article provides a clear overview of PH treatment options, stepwise guidelines for physicians, and educational video resources demonstrating botulinum toxin A injections with cryotherapy and nerve blocks.

Red blood cell antibody-induced anemia causes differential degrees of tissue hypoxia in kidney and brain.

Moderate anemia is associated with increased mortality and morbidity, including acute kidney injury (AKI), in surgical patients. A red blood cell (RBC)-specific antibody model was utilized to determine whether moderate subacute anemia could result in tissue hypoxia as a potential mechanism of injury. Cardiovascular and hypoxic cellular responses were measured in transgenic mice capable of expressing hypoxia-inducible factor-1α (HIF-1α)/luciferase activity in vivo. Antibody-mediated anemia was associated with mild intravascular hemolysis (6 h) and splenic RBC sequestration ( day 4), resulting in a nadir hemoglobin concentration of 89 ± 13 g/l on day 4. At this time point, renal tissue oxygen tension (PtO2) was decreased in anemic mice relative to controls (13.1 ± 4.3 vs. 20.8 ± 3.7 mmHg, P < 0.001). Renal tissue hypoxia was associated with an increase in HIF/luciferase expression in vivo ( P = 0.04) and a 20-fold relative increase in renal erythropoietin mRNA transcription ( P < 0.001) but no increase in renal blood flow ( P = 0.67). By contrast, brain PtO2 was maintained in anemic mice relative to controls (22.7 ± 5.2 vs. 23.4 ± 9.8 mmHg, P = 0.59) in part because of an increase in internal carotid artery blood flow (80%, P < 0.001) and preserved cerebrovascular reactivity. Despite these adaptive changes, an increase in brain HIF-dependent mRNA levels was observed (erythropoietin: P < 0.001; heme oxygenase-1: P = 0.01), providing evidence for subtle cerebral tissue hypoxia in anemic mice. These data demonstrate that moderate subacute anemia causes significant renal tissue hypoxia, whereas adaptive cerebrovascular responses limit the degree of cerebral tissue hypoxia. Further studies are required to assess whether hypoxia is a mechanism for acute kidney injury associated with anemia.
