Coronary CT angiography: a guide to examination, interpretation, and clinical indications

2021

Introduction: The introduction of Cardiac Computed Tomography (CCT) has changed the paradigm in the field of diagnostic cardiovascular medicine. CCT is the primary tool in the assessment of suspected Coronary Artery Disease (CAD) and should be followed by functional assessment when needed to stratify disease and to plan potential interventional or surgical therapy. Areas Covered: We provided the current state of the knowledge on the main aspects of technique of examination, image interpretation and clinical indications. We have focused our attention on the basic routine applications and activities. Expert Opinion: The primary role of CCT in suspected CAD will progressively become the standa…

Evaluating the statistical methodology of randomized trials on dentin hypersensitivity management

2017

The present study aimed to evaluate the characteristics and quality of statistical methodology used in clinical studies on dentin hypersensitivity management. An electronic search was performed for data published from 2009 to 2014 by using PubMed, Ovid/MEDLINE, and Cochrane Library databases. The primary search terms were used in combination. Eligibility criteria included randomized clinical trials that evaluated the efficacy of desensitizing agents in terms of reducing dentin hypersensitivity. A total of 40 studies were considered eligible for assessment of quality statistical methodology. The four main concerns identified were i) use of nonparametric tests in the presence of large samples…

Quantitative Musculoskeletal Ultrasound

2020

AbstractUltrasound (US) imaging plays a crucial role in the assessment of musculoskeletal (MSK) disorders. Several quantitative tools are offered by US systems and add information to conventional US imaging. This article reviews the quantitative US imaging tools currently available in MSK radiology, specifically focusing on the evaluation of elasticity with shear-wave elastography, perfusion with contrast-enhanced US and noncontrast superb microvascular imaging, and bone and muscle mass with quantitative US methods. Some of them are well established and already of clinical value, such as elasticity and contrast-enhanced perfusion assessment in muscles and tendons. MSK radiologists should be…

Residual coronary stenosis after thrombolysis with rt-PA or streptokinase: acute results and 3 weeks follow-up

1987

Ninety-one patients with acute myocardial infarction were assigned to intravenous treatment with streptokinase or rt-PA as part of the randomized trial carried out by the European Study Group for Recombinant Tissue-Type Plasminogen Activator (rt-PA). A patent coronary artery was found in 37 of 45 (82%) patients treated with rt-PA and in 27 of 46 (59%) patients treated with streptokinase 75-90 minutes after start of infusion. Patients were subsequently anticoagulated with heparin or dicoumarol up to a repeat angiography 3 weeks after the infarction. Of the 64 patients with successful reperfusion, 3 died and 3 suffered reocclusion of the vessel. Quantitative analysis of the coronary stenosis …

L’épistémologie de Jean Bollack ou Bollack contre Bollack

2015

International audience; Jean Bollack’s philologische Wissenschaft aims to reach the “good lesson” of a text and to get the “original intent” of its author, in the true sense of these expressions. It is based on three main elements: the identification of biases that would lead to an incorrect interpretation; the syntactic analysis of the text and the discussion of the points of view of other scholars (i.e. a dialectical criticism). Bollack – despite his accuracy – does not question his own assumptions: 1) that the sense of a text is in the manuscripts we possess (or – in any case – it is recoverable through them); 2) the idea that the great texts are more insightful than others; and 3) the n…

Estereotipos asociados al cuerpo humano: análisis de aplicaciones móviles usadas en la educación físico-deportiva

2022

Institutions and educators are massively and uncritically integrating digital curricular materials in their teaching praxis. This article aims to uncover whether health and fitness APP images convey or legitimize stereotypes linked to bodies, focusing on gender, race, somatotype and physical activity practice. We also analyse whether these apps are adequate for the recommended age or whether they are designed by physical education professionals. For that purpose, we designed a descriptive, comparative study based on content analysis on a sample of 373 images from 128 apps selected through a PRISMA review and a pilot test. Our results report that bodies reproduce a series of stereotypes: of …

Case series of fluoroscopic findings and 3D reconstruction of human spinal MRIs of the space of Okada.

2020

Objective To better understand the unexpected spread of contrast medium observed by conventional fluoroscopic X-ray images during standard neuraxial techniques used in the treatment of pain. The support of 3D reconstruction of MRI images of structures within the lumbar spine was used to better understand the space of Okada. Methods Lumbar facet joint and epidural corticosteroid injections in five patients under fluoroscopic guidance with loss of resistance to air or saline to identify the facet joints or epidural space. Next, in a retrospective study, the authors examined the retrodural space of Okada and the neighboring tissues with 3D reconstruction of spinal MRIs of seven patients withou…

La dimension musicale des textes des troubadours

2016

Saggio di complemento alla traduzione francese della grande antologia di testi trobadorici curata nel 1975 da Martin de Riquer. Si tratta di una introduzione alla tradizione musicale dei trovatori in cui si cerca di integrare la prospettiva musicologica a quella filologico-letteraria. Il saggio è articolato in tre paragrafi: 1. "Filologi e musicologi", in cui si discutono le diverse posizioni dei due ambiti disciplinari riguardo alle melodie dei trovatori; 2. "Tradizione scritta delle melodie", in cui si illustrano le modalità di trasmissione dei testi musicali con particolare riguardo alla tradizione stravagante e indiretta di melodie trobadoriche; 3. "Tipi musicali, generi poetici, genera…

Comparison of different theory models and basis sets in the calculation of 13C NMR chemical shifts of natural products.

2004

The influence of the calculation method in mimicking experimental 13C NMR chemical shifts of 15 low-polarity natural products singularly containing 10–20 carbon atoms was investigated by employing different quantum chemistry approaches and basis sets, both in the preliminary geometry optimizations and in the following single-point 13C GIAO calculations of the NMR chemical shifts. The geometries of the involved species were optimized at the PM3, HF, B3LYP and mPW1PW91 levels whereas the 13C NMR parameters were determined at the HF, B3LYP and mPW1PW91 levels. Different combinations of basis sets were also tested. The consistency and efficiency of the considered combinations of geometry optimi…
