RESUMO
BACKGROUND: Anterior uveitis, inflammation of the anterior chamber and related structures, is a cohort of diseases that can present to almost any general or sub-specialty Ophthalmology practice. Its features classically involve anterior chamber cell and flare. Below the surface of these two signs exist a panoply of diagnoses. BODY: The purpose of this review is to provide a general framework for diagnoses of anterior uveitis that are often missed as well as non-uveitic pathologies that often mimic anterior uveitis. Diagnostic deviation in either direction can have vision-threatening and rarely life-threatening consequences for patients. Using a comprehensive literature review we have collected a broad spectrum of etiologies of anterior uveitis that are easily missed and non-uveitic pathologies that can masquerade as anterior uveitis. CONCLUSIONS: We present a focused review on specific misdiagnosed anterior uveitis pathologies and some of the conditions that can masquerade as anterior uveitis and scleritis.
RESUMO
BACKGROUND: To assess the quality of clinical practice guidelines (CPGs) for chronic limb-threatening ischemia (CLTI) using the Appraisal of Guidelines for Research and Evaluation II instrument. METHODS: A systematic review of Medline, Embase, and online CPG databases was carried out. Four CPGs on CLTI were identified: Global Vascular Guidelines (GVG), European Society of Cardiology (ESC), American College of Cardiology, and National Institute for Health and Care Excellence guidelines on lower limb peripheral arterial disease. Two independent appraisers analyzed the 4 CPGs using the Appraisal of Guidelines for Research and Evaluation II instrument. CPGs were ranked across 6 domains with 23 items that ranged from 1 (strongly disagree) to 7 (strongly agree). A scaled domain score was calculated as a percentage of the maximum possible score achievable. A domain score of ≥50% and an overall average domain score of ≥80% reflected a CPG of adequate quality recommended for use. RESULTS: GVG had the highest overall score (82.9%), as an average of all domains, and ESC had the lowest score (50.2%). GVG and National Institute for Health and Care Excellence guidelines had all domains scoring >50%, while American College of Cardiology had 5 and ESC had 3. Two domains, rigor of development and applicability, scored the lowest among the CPGs. There was a lack of detail in describing systematic methods used in the literature review, how guidelines were formulated with minimal bias, and the planned procedure for updating the guidelines. Implications of guideline application and monitoring of outcomes after implementations were not explicitly discussed. CONCLUSIONS: The GVG guideline published in 2019 discussing CLTI is assessed to be of high quality and recommended for use. This review helps to improve clinical decision-making and quality of future CPGs for CLTI.
