Vasodepressor syncope and the diagnostic accuracy of the head-up tilt test with sublingual glyceryl trinitrate

open access: yes, 2003
Thirteen syncopal subjects and thirteen asymptomatic controls were examined by head-up tilt (HUT) with and without sublingual GTN.Adding GTN to HUT improved the sensitivity of the test (8 % to 46%) but decreasedPeter Athanasos, Daniel Sydenham, Jenny ...

Triangular Index Ratio as an Alternative Method to the Alpha Angle for Defining the Presence of Cam Morphology: A Prospective Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Cam morphology, which is a significant risk factor for hip osteoarthritis, is commonly quantified by the alpha angle (AA). This study aims to explore the potential of the triangular index ratio (TIR) to quantify cam morphology on anteroposterior radiographs by assessing the association between TIR‐defined cam morphology and the development of
