A nomogram to predict sentinel node (SN) positivity [the Melanoma Institute Australia (MIA) nomogram] was recently developed and externally validated using two large single-institution databases. However, there remains a need to further validate the nomogram's performance using population-based data. ⋯ This population-based validation study in European patients with melanoma confirmed the value of the MIA nomogram in predicting SN positivity. Its use will spare low-risk patients the inconvenience, cost and potential risks of SN biopsy while ensuring that high-risk patients are still identified.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of fumaric acid esters in young patients aged 10-17 years with moderate-to-severe plaque psoriasis: a randomized, double-blinded, placebo-controlled trial.
Apart from biologics, no systemic drugs are approved in Europe for children with moderate-to-severe psoriasis. Retrospective observational studies have shown promising results for fumaric acid esters (FAE) in this setting. ⋯ FAE administered over a period of 20 weeks demonstrated a better response than placebo; the difference was statistically significant and clinically meaningful. Application up to 40 weeks was generally well tolerated. However, further studies are required.

Randomized Controlled Trial
A head-to-head comparison of ixekizumab vs. guselkumab in patients with moderate-to-severe plaque psoriasis: 24-week efficacy and safety results from a randomized, double-blinded trial.
Significantly more patients with moderate-to-severe plaque psoriasis treated with the interleukin (IL)-17A inhibitor ixekizumab vs. the IL-23p19 inhibitor guselkumab in the IXORA-R head-to-head trial achieved 100% improvement in Psoriasis Area and Severity Index (PASI 100) at week 12. ⋯ Ixekizumab was noninferior to guselkumab in complete skin clearance and superior in clearing nails at week 24. Ixekizumab cleared skin more rapidly in patients with moderate-to-severe plaque psoriasis, with a greater cumulative benefit, than guselkumab. Overall, the safety findings were consistent with the known safety profile for ixekizumab.

Randomized Controlled Trial
Secukinumab 2-weekly vs. 4-weekly dosing in patients with plaque-type psoriasis: results from the randomized GAIN study.
Secukinumab is a fully human monoclonal antibody that selectively neutralizes interleukin-17A and shows long-lasting efficacy and safety in plaque psoriasis. More evidence is required to optimize secukinumab dosing according to clinical response. ⋯ Most patients achieved PASI 90 response with secukinumab q4w. There was potential benefit of q2w dosing in some suboptimal responders. Continued q4w treatment can improve response even after 16 weeks.
