Epidemiological, Clinical and Allergic Profile of Patients With Dyshidrotic Eczema (Acute and Recurrent Vesicular Dermatitis): Evaluation of the Spanish Registry of Research in Contact Dermatitis and Cutaneous Allergy (REIDAC)

open access: yesContact Dermatitis, Volume 95, Issue 3, Page 286-294, September 2026.
In this exploratory analysis, dyshidrotic eczema demonstrated a distinct sensitisation pattern compared with non‐dyshidrotic hand eczema. The lower proportion of clinically relevant reactions amongst positive patch tests suggests a multi‐factorial and not exclusively allergic background.

Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

open access: yesPest Management Science, Volume 82, Issue 8, Page 7951-7960, August 2026.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...
