To describe an asymptomatic presentation of severe hypocalcemia secondary to vitamin D deficiency in an elderly patient.<jats:italic>Methods<\/jats:italic>. We describe the presentation and clinical course of an elderly woman with asymptomatic severe hypocalcemia referred to an endocrinology clinic for hyperparathyroidism.<jats:italic>Results<\/jats:italic>. The patient is an 83-year-old Caucasian woman who presented to an endocrinology clinic for evaluation of hyperparathyroidism, with an intact PTH of 462\u2009pg\/mL (normal range 14\u201372\u2009pg\/mL). The same lab report included a serum calcium of 5.2\u2009mg\/dL (normal range 8\u201310.5\u2009mg\/dL). She displayed no signs or symptoms of hypocalcemia. Given the extreme severity of hypocalcemia and her age, she was hospitalized. Vitamin D deficiency was suspected and was subsequently confirmed with undetectable serum levels. The patient remained asymptomatic throughout her hospital stay. Total and ionized calcium levels at discharge were 7.2\u2009mg\/dL and 1.03\u2009mmol\/L (normal range 1.1\u20131.4\u2009mmol\/L), respectively.<jats:italic>Conclusion<\/jats:italic>. Physicians should exercise prudent management with respect to the vitamin D status of the elderly patient, as certain patients may exhibit severe hypovitaminosis D and hypocalcemia without apparent clinical symptoms.<\/jats:p>","DOI":"10.1155\/2011\/830952","type":"journal-article","created":{"date-parts":[[2011,11,2]],"date-time":"2011-11-02T21:00:52Z","timestamp":1320267652000},"page":"1-3","source":"Crossref","is-referenced-by-count":3,"title":["Asymptomatic Severe Hypocalcemia Secondary to Vitamin D Deficiency in an Elderly Patient"],"prefix":"10.1155","volume":"2011","author":[{"given":"Saleh","family":"Aldasouqi","sequence":"first","affiliation":[{"name":"Endocrine Division, Department of Medicine, Michigan State University, Lansing, MI 48910, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Crystal M.","family":"Glassy","sequence":"additional","affiliation":[{"name":"College of Osteopathic Medicine, Michigan State University, Lansing, MI 48910, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew S.","family":"Glassy","sequence":"additional","affiliation":[{"name":"College of Human Medicine, Michigan State University, Lansing, MI 48910, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anxhela","family":"Treska","sequence":"additional","affiliation":[{"name":"Georgia Health Sciences University, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Molly","family":"Caldwell-McMillan","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine in St. Louis, St. Louis, MO 63110, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ved","family":"Gossain","sequence":"additional","affiliation":[{"name":"Endocrine Division, Department of Medicine, Michigan State University, Lansing, MI 48910, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1024\/0300-9831.78.6.286"},{"issue":"21","key":"2","doi-asserted-by":"crossref","first-page":"1683","DOI":"10.1001\/jama.1995.03530210037027","volume":"274","year":"1995","journal-title":"Journal of the American Medical Association"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2003-030515"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1023\/A:1015263514765"},{"issue":"4","key":"5","doi-asserted-by":"crossref","first-page":"640","DOI":"10.1590\/S0004-27302006000400009","volume":"50","year":"2006","journal-title":"Arquivos Brasileiros de Endocrinologia e Metabologia"},{"issue":"2b","key":"6","doi-asserted-by":"crossref","first-page":"547","DOI":"10.1079\/PHN2001140","volume":"4","year":"2001","journal-title":"Public Health Nutrition"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2265.2005.02226.x"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/S0736-4679(97)00240-0"},{"issue":"14","key":"9","doi-asserted-by":"crossref","first-page":"869","DOI":"10.1056\/NEJM198209303071407","volume":"307","year":"1982","journal-title":"New England Journal of Medicine"},{"key":"10","doi-asserted-by":"crossref","first-page":"1","DOI":"10.2174\/1874216500903010001","volume":"3","year":"2009","journal-title":"The Open Endocrinology Journal"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1155\/2011\/141024"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2008.08.050"}],"container-title":["Case Reports in Endocrinology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crie\/2011\/830952.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crie\/2011\/830952.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crie\/2011\/830952.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,6,19]],"date-time":"2019-06-19T00:39:49Z","timestamp":1560904789000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/crie\/2011\/830952\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":12,"alternative-id":["830952","830952"],"URL":"https:\/\/doi.org\/10.1155\/2011\/830952","relation":{},"ISSN":["2090-6501","2090-651X"],"issn-type":[{"value":"2090-6501","type":"print"},{"value":"2090-651X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011]]}}}
