Rosacea diagnosis and treatment in children are challenging, due to its rarity and to the lack of approved pharmacological agents for its treatment in this age group. In this case series, response to treatment with once daily applications of ivermectin (IVM) 1% cream for 12 weeks in 10 children affected by mild to severe inflammatory rosacea was evaluated clinically by Investigator Erythema Severity Assessment (IESA), Investigator Global Assessment of Severity (IGA-S), Investigator Global Assessment score of Global Efficacy (IGA-GE), and instrumentally by dermoscopy and Erythema-Directed Digital Photography (EDDP). Clinical improvement was achieved at the end of treatment compared to baseline (IESA: 2.3 vs. 0.5; IGA-S: 2.1 vs. 0.3) and confirmed by IGA-GE (0 = 55%, 1 = 33%, 3 = 11%) and instrumental monitoring (EDDP: 2.7 vs. 0.6). Once daily IVM application may be an effective therapeutic option for children with rosacea., (© 2024 Wiley Periodicals LLC.)

Aim: Cell microenvironment contains a plethora of information that influences cell modulation. Indeed, the extracellular matrix plays a central role in tissue development. Reproducing the cell-extracellular matrix crosstalk able to recapitulate both physical and biochemical signals is crucial to obtain functional tissue models or regenerative strategies. Materials & methods: Here, a combined method is proposed to easily functionalize collagen surface films, tailoring morphological properties. Oxygen nonthermal plasma treatment and glyco-conjugation with chondroitin sulfate are used to modify surface properties. Results: It results in higher adhesion, proliferation and morphological organization of U87 glioblastoma cells. Conclusion: Our finding suggests new promising strategies for the development of collagen-based biomaterials, which can be employed for advanced in vitro models.
