The nail is considered one of the\u00a0possible targets of assessment, especially when ultrasonography is performed.\u00a0The aim of the study is to highlight peculiar features and alterations of the nail unit in patients affected by psoriasis and\u00a0psoriatic arthritis versus healthy controls using ultrasonography.Materials and methods: The study sample included 82 patients\u00a0affected by psoriasis and\/or psoriatic arthritis and 50 healthy controls. The patients were consecutively enrolled during\u00a0their routine visit in the outpatient clinic and they performed clinical and ultrasonographic evaluation of the nail. The evaluationof disease activity was done using Disease Activity in Psoriatic Arthritis (DAPSA), Psoriasis Activity Severity Index\u00a0(PASI), and Nail Psoriasi Severity Index (NAPSI).Results: Multivariate analysis of variance was performed between groups.\u00a0Post hoc analysis underlined the differences between healthy and affected regarding nail plate thickness (0.063\u00b10.011 cm for\u00a0patients with psoriasis, 0.065\u00b10.014 cm for patients with psoriatic arthritis and 0.051\u00b10.006 cm for healthy controls, p&lt;0.05).\u00a0Elementary lesions of nail plate and nail bed were compared using Pearson\u2019s chi square test between patients in psoriasis and\u00a0psoriatic arthritis groups, with no differences except for a trend for onycholisis and crumbling (p=0.07 and 0.06, respectively)\u00a0in the psoriatic arthritis group. ROC curves were calculated (AUC = 0.68) obtaining also quantitative cut offs for nail plate andnail bed thickness in the affected vs healthy patients.Conclusions: Our study shows that ultrasonography may be a potential\u00a0advantage in clinical practice. Our results strengthen the information already available in the literature and add quantitative\u00a0parameters for ultrasonography of the nail.<\/jats:p>","DOI":"10.11152\/mu-1327","type":"journal-article","created":{"date-parts":[[2018,3,6]],"date-time":"2018-03-06T11:55:15Z","timestamp":1520337315000},"page":"177","source":"Crossref","is-referenced-by-count":26,"title":["Ultrasonography of the nail unit reveals quantitative and qualitative alterations in patients with psoriasis and psoriatic arthritis"],"prefix":"10.11152","volume":"20","author":[{"given":"Luca","family":"Idolazzi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Gisondi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelo","family":"Fassio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ombretta","family":"Viapiana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Giollo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurizio","family":"Rossini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giampiero","family":"Girolomoni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Davide","family":"Gatti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4840","published-online":{"date-parts":[[2018,5,2]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/1327\/1152","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/1327\/1152","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,5,2]],"date-time":"2018-05-02T18:09:40Z","timestamp":1525284580000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/1327"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,5,2]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2018,5,2]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-1327","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2018,5,2]]}}}
