Topical corticosteroids (TCS) are commonly used in dermatology for their anti-inflammatory action. The recent development of the TOPICOP© (Topical Corticosteroid Phobia) scale to assess steroid phobia has made the quantification and comparison of steroid phobia easier. The objective of this study was to assess the degree of steroid phobia at our institute and identify sources from which patients obtain information regarding TCS. ⋯ The prevalence of steroid phobia in our dermatology outpatient setting was moderately high, with gender differences. Dermatologists were the most common source of information on TCS, and it was heartening to note that trust was also highest in dermatologists. Strategies to target steroid phobia should take into account these factors.

Computed tomography coronary angiography (CTCA) is a robust and reliable non-invasive alternative imaging modality to invasive coronary angiography, which is the reference standard in evaluating the degree of coronary artery stenosis. CTCA has high negative predictive value and can confidently exclude significant coronary artery disease (CAD) in low to intermediate risk patients. ⋯ In this review, we present the evolution of computed tomography scanners in the context of coronary artery imaging as well as its clinical applications and limitations. We also highlight the future directions of CTCA as a one-stop non-invasive imaging modality for anatomic and functional assessment of CAD.
