Physical examination showed stridor, tachypnoea with use of accessory muscles of respiration on admission. Laboratory tests were unremarkable except for monocytosis with a normal total white cell count. Rapid influenza diagnostic test was positive for influenza A. Chest X-ray showed subglottic narrowing of the trachea suggestive of steeple sign. A diagnosis of influenza A-induced croup was made. She was given humidified oxygen, nebulised racemic epinephrine, intravenous dexamethasone and oseltamivir. Stridor resolved within minutes of giving nebulised epinephrine. Work of breathing improved within 4\u20136\u2009hours. She was discharged 2\u2009days later on a tapering dose of steroids.<\/jats:p>","DOI":"10.1136\/bcr-2017-223974","type":"journal-article","created":{"date-parts":[[2018,6,4]],"date-time":"2018-06-04T07:30:23Z","timestamp":1528097423000},"page":"bcr-2017-223974","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Uncommon presentation of a common disease: influenza A presenting as adult croup\u202f"],"prefix":"10.1136","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3092-4664","authenticated-orcid":false,"given":"Nasreen","family":"Shaikh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7836-271X","authenticated-orcid":false,"given":"Prudence","family":"Dy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amrit","family":"Basnet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shilpan","family":"Shah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,6,4]]},"reference":[{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.1","doi-asserted-by":"crossref","first-page":"421","DOI":"10.1002\/ppul.22993","article-title":"Viral croup: Diagnosis and a treatment algorithm","volume":"49","author":"Petrocheilou","year":"2014","journal-title":"Pediatr Pulmonol"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.2","doi-asserted-by":"publisher","DOI":"10.1097\/00006454-200201000-00020"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.3","doi-asserted-by":"crossref","first-page":"457","DOI":"10.1288\/00005537-199005000-00002","article-title":"Infectious adult croup","volume":"100","author":"Deeb","year":"1990","journal-title":"Laryngoscope"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.4","doi-asserted-by":"publisher","DOI":"10.1378\/chest.109.6.1659"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2006.11.013"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.6","doi-asserted-by":"publisher","DOI":"10.1159\/000056301"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.7","doi-asserted-by":"crossref","first-page":"96","DOI":"10.3390\/v8040096","article-title":"Current approaches for diagnosis of influenza virus infections in humans","volume":"8","author":"Vemula","year":"2016","journal-title":"Viruses"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.8","first-page":"1","article-title":"A narrowing diagnosis: a rare cause of adult croup and literature review","volume":"2017","author":"Patel","year":"2017","journal-title":"Case Rep Crit Care"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.9","doi-asserted-by":"crossref","first-page":"e23","DOI":"10.1164\/rccm.201207-1306IM","article-title":"A catastrophic presentation of adult croup","volume":"187","author":"Parimon","year":"2013","journal-title":"Am J Respir Crit Care Med"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.10","doi-asserted-by":"publisher","DOI":"10.2353\/ajpath.2010.100115"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.11","doi-asserted-by":"crossref","first-page":"443","DOI":"10.1016\/j.medmal.2017.06.006","article-title":"Update on childhood and adult infectious tracheitis","volume":"47","author":"Blot","year":"2017","journal-title":"Med Mal Infect"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.12","doi-asserted-by":"publisher","DOI":"10.1503\/cmaj.121645"},{"key":"2025042703482670000_2018.jun01_1.bcr-2017-223974.13","doi-asserted-by":"publisher","DOI":"10.1093\/bmb\/61.1.189"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2017-223974","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T10:48:36Z","timestamp":1745750916000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2017-223974"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,6,4]]},"references-count":13,"alternative-id":["10.1136\/bcr-2017-223974"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2017-223974","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2018,6,4]]}}}
