Recommendations for rosacea diagnosis, classification and management: update from the global ROSacea COnsensus 2019 panel.

BACKGROUND: A transition from a subtyping to a phenotyping approach in rosacea is underway, allowing individual patient management according to presenting features instead of categorization by predefined subtypes. The ROSacea COnsensus (ROSCO) 2017 recommendations further support this transition and align with guidance from other working groups. OBJECTIVES: To update and extend previous global ROSCO recommendations in line with the latest research and continue supporting uptake of the phenotype approach in rosacea through clinical tool development. METHODS: Nineteen dermatologists and two ophthalmologists used a modified Delphi approach to reach consensus on statements pertaining to critical aspects of rosacea diagnosis, classification and management. Voting was electronic and blinded. RESULTS: Delphi statements on which the panel achieved consensus of ≥ 75% voting 'Agree' or 'Strongly agree' are presented. The panel recommends discussing disease burden with patients during consultations, using four questions to assist conversations. The primary treatment objective should be achievement of complete clearance, owing to previously established clinical benefits for patients. Cutaneous and ocular features are defined. Treatments have been reassessed in line with recent evidence and the prior treatment algorithm updated. Combination therapy is recommended to benefit patients with multiple features. Ongoing monitoring and dialogue should take place between physician and patients, covering defined factors to maximize outcomes. A prototype clinical tool (Rosacea Tracker) and patient case studies have been developed from consensus statements. CONCLUSIONS: The current survey updates previous recommendations as a basis for local guideline development and provides clinical tools to facilitate a phenotype approach in practice and improve rosacea patient management. What's already known about this topic? A transition to a phenotype approach in rosacea is underway and is being recommended by multiple working groups. New research has become available since the previous ROSCO consensus, necessitating an update and extension of recommendations. What does this study add? We offer updated global recommendations for clinical practice that account for recent research, to continue supporting the transition to a phenotype approach in rosacea. We present prototype clinical tools to facilitate use of the phenotype approach in practice and improve management of patients with rosacea.

Onychomycosis in children: prevalence and management.

Onychomycosis in children is often accompanied by tinea pedis and a family history of onychomycosis. The prevalence of onychomycosis in children is substantially lower than that of adults; therefore it is important to confirm the clinical diagnosis. The most common presentation of onychomycosis is the distal and lateral subungual type. The organism most commonly isolated in North America is Trichophyton rubrum. Oral antifungal therapy is required, especially when the onychomycosis is of moderate to severe intensity, with nail matrix involvement. The new oral antifungal agents itraconazole, terbinafine, and fluconazole are being increasingly used for the treatment of onychomycosis. Review of the literature suggests that these agents are effective and safe in managing onychomycosis in children. The short duration of therapy required with these drugs should help improve compliance. The data suggest that the new oral antifungal agents have a role in the treatment of onychomycosis in children. Further experience will help us better position these drugs when evaluating the management of onychomycosis in children.
