What Actually Changes Practice (and What Doesn’t)

The DECIDE study indicates that the 31-gene expression profile test for cutaneous melanoma provides limited stratification for thicker tumors, leaving the clinical utility of sentinel lymph node biopsies for T1B lesions unresolved. Management of bullous pemphigoid remains contentious, with U.S. specialists favoring systemic corticosteroids and rituximab over the topical corticosteroid-heavy protocols recommended by European guidelines. While dupilumab shows efficacy in chronic spontaneous urticaria, it fails to address chronic inducible urticaria, where mast cell-targeting agents like barzolivimab show promise despite potential side effects. Furthermore, melatonin supplementation demonstrates potential in treating atopic dermatitis by improving SCORAD scores, while emerging data suggests a correlation between high-dose gabapentinoid use and increased dementia risk, particularly in younger patients, highlighting the need for cautious prescribing practices in dermatology.
