Here, we report two cases of deep pressure ulcers in patients with acute monoarthritis as a result of calcium pyrophosphate (CPP) crystal deposition (pseudogout). The patients were women in their 80 who could perform activities of daily living by themselves. They developed pressure ulcers while living in their own home. Because acute CPP crystal arthritis is known to develop in relatively healthy elderly patients, patients and caregivers do not expect sudden\u2010onset immobilisation. In addition, larger joints are preferentially involved in acute CPP crystal arthritis, leading to the inability of patients to change positions themselves. Therefore, acute CPP crystal arthritis should be recognised as a potential causal disease for pressure ulcers. This case report further highlights a new concept of \u201cdisease\u2010specific unexpected external force\u201d, which is beneficial for the prevention of pressure ulcers.<\/jats:p>","DOI":"10.1111\/iwj.13009","type":"journal-article","created":{"date-parts":[[2018,10,31]],"date-time":"2018-10-31T13:07:21Z","timestamp":1540991241000},"page":"556-558","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Two cases of pressure ulcers related to acute calcium pyrophosphate crystal arthritis: A new concept of \u201cdisease\u2010specific unexpected external forces\u201d"],"prefix":"10.1111","volume":"16","author":[{"given":"Fumihiro","family":"Mizokami","sequence":"first","affiliation":[{"name":"Department of Pharmacy National Center for Geriatrics and Gerontology  Obu Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiko","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Nursing &amp; Health, School of Nursing &amp; Health Aichi Prefectural University  Nagoya Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zenzo","family":"Isogai","sequence":"additional","affiliation":[{"name":"Division of Dermatology and Connective Tissue Medicine National Center for Geriatrics and Gerontology  Obu Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,10,31]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijnurstu.2012.11.019"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/kep081"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2010.139360"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/1346-8138.13093"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/mds.23449"},{"key":"e_1_2_5_7_1","first-page":"313","article-title":"Parkinson syndrome \u2013 a significant risk factor in the patient with acute surgical disorder","volume":"77","author":"Simon D","year":"1992","journal-title":"Int Surg"},{"key":"e_1_2_5_8_1","first-page":"20","article-title":"A comparative, descriptive study of systemic factors and survival in elderly patients with sacral pressure ulcers","volume":"61","author":"Jaul E","year":"2015","journal-title":"Ostomy Wound Manage"}],"container-title":["International Wound Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fiwj.13009","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/iwj.13009","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/iwj.13009","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/iwj.13009","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T12:47:08Z","timestamp":1748350028000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/iwj.13009"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,31]]},"references-count":7,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2019,4]]}},"alternative-id":["10.1111\/iwj.13009"],"URL":"https:\/\/doi.org\/10.1111\/iwj.13009","archive":["Portico"],"relation":{},"ISSN":["1742-4801","1742-481X"],"issn-type":[{"type":"print","value":"1742-4801"},{"type":"electronic","value":"1742-481X"}],"subject":[],"published":{"date-parts":[[2018,10,31]]},"assertion":[{"value":"2018-05-18","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-09-18","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-10-31","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
