Take-home messages

A clinician should always look for clues of nail disease in a psoriatic patient.

Nail involvement is strongly associated with the psychological burden and can independently affect the therapeutic response.

Future trials concerning patients with skin and nail psoriasis should always include a quality of life assessment tool together with clinical severity indexes.

NAPSI, PASI and DLQI are reliable, reproducible, and positively correlated indexes and are, therefore, suggested for the evaluation of patients suffering from skin and nail psoriasis.
