The STRIPP questionnaire (Screening Tool for Rheumatologic Investigation in Psoriatic Patients) as a new tool for the diagnosis of early psoriatic arthritis.

Background: Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis in up to one third of psoriatic patients. Clinically it's characterized from an insidious onset. To help clinicians screen for PsA, several screening tools have been developed.

Prevalence of stratified epithelium-specific antinuclear antibodies in 138 patients with lichen planus.

Background: Antibodies to stratified epithelia characterize chronic ulcerative stomatitis, an entity that very closely resembles erosive lichen planus both clinically and histologically. These antibodies are directed against a 70-kd antigen.

Objective: Our aim was to verify whether antibodies to stratified epithelia are present in patients with common lichen planus.
