Background Cutaneous adverse drug reactions (CADRs) remain a challenge for non-dermatologists. Medical-related applications to assist in learning about and managing patients with CADRs are scarce. We aimed to evaluate the efficacy of a web application for non-dermatologists in managing CADRs by comparing the knowledge scores of users and non-users.Materials and Methods A multicenter randomized controlled trial was conducted between January 2023 and May 2023. Clinician participants were randomized (1:1) into the application and control groups using a simple randomization method. Knowledge scores between the groups were compared to evaluate the efficacy of the web application, and participants’ perspectives on the application were also collected.Results A total of 44 clinician participants were included in the final analysis. The median age was 33.0 years (95% confidence interval (CI) 27.5–35.0) and predominantly female (56.8%). The score in the application group (median, 27.0; 95% CI, 25.0–28.0) was significantly higher than that in the control group (median, 14.0; 95% CI 13.0–17.0) (p

Abstract Background Linear cutaneous lupus erythematosus (LE) is an unusual form of LE-specific cutaneous condition, occurring in children and young adults. Due to its rarity, the diagnosis of linear cutaneous LE can be difficult and facial lesions can resemble linear morphea or en coup de sabre. Differential diagnosis of similar conditions along the lines of Blaschko must be differentiated from linear LE. Case presentation We report a case of linear discoid LE on the forehead of an adult female Thai patient mimicking en coup de sabre. The dermatoscopy, histopathology and direct immunofluorescence findings were consistent with chronic cutaneous LE. Conclusions As this patient demonstrated classic dermatoscopic features of LE, we emphasized that the diagnosis of linear cutaneous LE can be made by dermatoscopy. This is particularly beneficial for young self-conscious patients with facial lesions that are reluctant to perform skin biopsy.

The informed consent process is integral to medical procedures, including skin biopsies, which are the definitive method for diagnosing challenging skin lesions. Educational videos are recognized for effective delivery of information for informed consent. This study aimed to evaluate the efficacy of an informed consent process using educational videos to improve patient understanding and reduce preprocedural anxiety. This multicenter, randomized controlled study was conducted during December 2021-June 2023. Participants were randomly assigned to either the video or verbal group in a 1:1 ratio. They completed knowledge and anxiety questionnaires before and after biopsy. The final analysis included 54 participants (verbal group: n=28; video group: n=26) with a mean age of 51.9 years (standard deviation [SD] 18.1), and a balanced gender distribution. Post-intervention knowledge scores (median 10.0; IQR 8.0-10.0) significantly increased compared to pre-intervention scores (median 6.0; IQR 4.0-9.0), p<0.001. Post-intervention Spielberger state-trait anxiety inventory (STAI) scores (median 5.0; interquartile range, IQR 5.0-6.0) significantly decreased compared to pre-intervention scores (median 7.0; IQR 5.0-10.0), p<0.001. Knowledge scores increased more in the video group (median, 2.5; IQR 1.0-5.0) than in the verbal group (median, 1.5; IQR 0.0-4.0), p=0.217. There was no significant difference in STAI score changes between the video group (median 1.0, IQR 0.0-4.0) and the verbal group (median 1.0, IQR 0.0-3.0), p=0.824. Despite statistical insignificance, educational videos exhibited greater effectiveness in enhancing comprehension and demonstrated comparable efficacy in reducing anxiety compared to conventional intervention.
