A labelling system improves parental comfort and willingness to use topical corticosteroids for paediatric atopic dermatitis.

Objectives: In the United Kingdom, atopic dermatitis (AD) affects 20% of children and topical corticosteroids (TCS) are a mainstay of AD treatment regimes. Many TCS have similar packaging despite significant differences in potency frequently leading to confusion, and along with misinformation and steroid phobia, potentially reducing treatment adherence. We aimed to evaluate parents' knowledge/concerns regarding TCS and explore benefits of/preference for a TCS-labelling system. Method: Hundred parents of children with AD attending paediatric dermatology and/or allergy appointments completed mixed-methodology Survey 1 (knowledge-quiz, TCS-labelling options, feedback on what supports AD-care). Thirty parents, adolescents, and healthcare professionals completed Survey 2. Qualitative/quantitative data was thematically/statistically analysed (SPSS v25) respectively. Results: Parents preferred the traffic light system (green = mild, yellow = moderate, red = potent; n = 71/100) and reported significantly increased willingness and comfort in using TCS if a labelling system was used p ≤ 0.001). Knowledge regarding TCS potency was lacking: 62% (n = 46/74) of mild TCS-users overestimated potency; 51% (n = 67/131) of potent TCS-users underestimated potency. Common concerns were TCS-related skin thinning, long-term side effects and themes for improved AD-care/support included: better information, written plans, access to advice, involvement of certain staff. Parents wanted accessible information in various formats: verbally, electronic resources, leaflets, and education sessions. Conclusions: Parents of children with AD confirmed significant concerns and demonstrated poor knowledge regarding TCS use. Our findings suggest that a simple labelling system may improve TCS adherence. Future work to test refined label prototypes and evaluating their impact on adherence and correct use is needed.

Compact sensitive instrument for direct ultrasonic visualization of defects.

A simple ultrasonic imaging cell based on the confocal combination of a plano-concave lens and a concave spherical mirror is described. When used in conjunction with a stroboscopic schlieren visualization system, it has the main attributes of a practical nondestructive testing instrument: it is compact, relatively inexpensive, and simple to operate; its sensitivity is fair, resolution and fidelity are good; it has a fairly large field of view and a test piece can be readily scanned. The scope of its applicability is described and discussed.
