Statistical analysis was performed using IBM SPSS Statistics\u00ae, version 27.0.\nResults: A total of 2254 episodes of urticaria were counted with 98.1% corresponding to acute urticaria (AU). A suspected trigger factor was identified in 51.6% of the episodes, namely infections (27.8%), drugs (9.9%) and food (7.6%). From these episodes, excluding infections, only 59.2% were referred to an Allergy Consultation for further study, with only 18.8% (drug) and 28.3% (food) confirmed as the AU trigger. Of the 43 episodes of chronic urticaria (CU), 79% were referred to consultation, with 23 being diagnosed with chronic spontaneous urticaria, 8 with inducible urticaria and 3 with both entities. Older age (p &lt; 0.001), personal history of atopy (p = 0.019) and angioedema (p = 0.003) were factors associated with CU, while the presence of other accompanying symptoms (p = 0.007) was associated with AU. Older age (OR = 1.2; p &lt; 0.001) and the presence of angioedema (OR = 2.7; p = 0.007) were identified as indepen-dent factors for CU.\nConclusion: The majority of episodes corresponded to AU. Infections were the main suspected trigger, followed by drugs and food, with an overall confirmation rate ranging from 18 to 30%, highlighting the importance of an allergologic follow-up evaluation.<\/jats:p>","DOI":"10.15586\/aei.v51i3.820","type":"journal-article","created":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T11:20:52Z","timestamp":1683285652000},"page":"117-123","source":"Crossref","is-referenced-by-count":3,"title":["Hospital admissions for urticaria in a pediatric emergency  department of a tertiary care hospital"],"prefix":"10.15586","volume":"51","author":[{"given":"In\u00eas","family":"Costa Farinha","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helena","family":"Pires Pereira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f3nia","family":"Gaspar Lemos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Em\u00edlia","family":"Faria","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernanda","family":"Rodrigues","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6228","published-online":{"date-parts":[[2023,5,1]]},"container-title":["Allergologia et Immunopathologia"],"original-title":[],"link":[{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/download\/820\/1300","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/download\/820\/1301","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/download\/820\/1302","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/download\/820\/1300","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T11:20:53Z","timestamp":1683285653000},"score":1,"resource":{"primary":{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/view\/820"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,5,1]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2023,5,1]]}},"URL":"https:\/\/doi.org\/10.15586\/aei.v51i3.820","relation":{},"ISSN":["0301-0546"],"issn-type":[{"value":"0301-0546","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,5,1]]}}}
