Kawada <jats:italic>et\u00a0al<\/jats:italic>. have reported data for 1982\u20132001 and Takahashi <jats:italic>et\u00a0al<\/jats:italic>. have reported data for 2002\u20132008. The present study evaluated 9290 psoriatic cases according to age and sex (2009\u20132012). The male\u00a0:\u00a0female ratio was 2.08:1 (6281 male patients [67.6%] to 3009 female patients [32.4%]). The most prevalent type was psoriasis vulgaris (85.6% of all cases), which was followed by psoriasis arthropathica (6.0%), psoriasis guttate acuta (3.2%), Zumbusch\u2010type generalized pustular psoriasis (1.8%) and psoriasis erythroderma (1.5%). Psoriasis vulgaris was the most prevalent type for all ages, while psoriasis arthropathica and psoriasis guttate acuta were most prevalent among patients aged less than 65\u00a0years. The present survey detected an increased number of cases with comorbid diabetes and\/or arthritis symptoms compared with the previous surveys. We found that treatments frequently involved topical corticosteroids (89.7% of cases) and vitamin D<jats:sub>3<\/jats:sub> ointments (78.0% of cases), with a notable increase in the use of vitamin D<jats:sub>3<\/jats:sub> ointments. Systemic treatments were used in 33.3% of cases, including cyclosporin (33.6%), etretinate (19.5%), methotrexate (8.6%), infliximab (11.4%), adalimumab (10.9%) and ustekinumab (6.2%). Phototherapy was used in 30.9% of cases. Although psoralen plus ultraviolet A therapy was the predominant phototherapy during previous studies, the present survey revealed that narrowband ultraviolet B therapy was used in 84.5% of phototherapy\u2010treated cases. Thus, the present survey revealed major changes in treatment trends.<\/jats:p>","DOI":"10.1111\/1346-8138.14105","type":"journal-article","created":{"date-parts":[[2017,11,8]],"date-time":"2017-11-08T13:12:37Z","timestamp":1510146757000},"page":"293-301","source":"Crossref","is-referenced-by-count":49,"title":["Epidemiological survey from 2009 to 2012 of psoriatic patients in Japanese Society for Psoriasis Research"],"prefix":"10.1111","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8568-8187","authenticated-orcid":false,"given":"Toshihiro","family":"Ito","sequence":"first","affiliation":[{"name":"Department of Dermatology The Jikei University School of Medicine Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidetoshi","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Dermatology Asahikawa Medical University Asahikawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akira","family":"Kawada","sequence":"additional","affiliation":[{"name":"Department of Dermatology Kinki University School of Medicine Osaka\u2010Sayama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hajime","family":"Iizuka","sequence":"additional","affiliation":[{"name":"Department of Dermatology Asahikawa Medical University Asahikawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidemi","family":"Nakagawa","sequence":"additional","affiliation":[{"name":"Department of Dermatology The Jikei University School of Medicine Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Japanese Society For Psoriasis Research","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,11,8]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0923-1811(02)00142-1"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1346-8138.2010.01145.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2014-006450"},{"issue":"1","key":"e_1_2_6_5_1","first-page":"19","article-title":"Epidemiology of psoriasis and psoriatic arthritis","volume":"59","author":"Cimmino MA","year":"2007","journal-title":"Reumatismo"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-3083.2010.03600.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.2340\/00015555-0642"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ad.2011.03.022"},{"key":"e_1_2_6_9_1","first-page":"112","article-title":"Epidemiology of psoriasis in Malaysia: a hospital based study","volume":"65","author":"Sinniah B","year":"2010","journal-title":"Med J Malaysia"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1684\/ejd.2012.1802"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1159\/000111511"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/1346-8138.13342"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.3899\/jrheum.141598"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamadermatol.2013.5264"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1346-8138.2011.01408.x"}],"container-title":["The Journal of Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2F1346-8138.14105","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1346-8138.14105","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,12]],"date-time":"2023-09-12T03:59:43Z","timestamp":1694491183000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1346-8138.14105"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,11,8]]},"references-count":14,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2018,3]]}},"alternative-id":["10.1111\/1346-8138.14105"],"URL":"https:\/\/doi.org\/10.1111\/1346-8138.14105","archive":["Portico"],"relation":{},"ISSN":["0385-2407","1346-8138"],"issn-type":[{"value":"0385-2407","type":"print"},{"value":"1346-8138","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,11,8]]}}}
