Charcot foot is a rare and devastating complication of diabetes. While some risk factors are known, debate continues regarding etiology. Elucidating other associated disorders and their temporal occurrence could lead to a better understanding of its pathogenesis. We applied a large data mining approach to Charcot foot for elucidating novel associations.<jats:italic>Methods<\/jats:italic>. We conducted an association analysis using ICD-9 diagnosis codes for every patient in our health system (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>n<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>1.6<\/mml:mn><\/mml:math>million with 41.2 million time-stamped ICD-9 codes). For the current analysis, we focused on the 388 patients with Charcot foot (ICD-9 713.5).<jats:italic>Results<\/jats:italic>. We found 710 associations, 676 (95.2%) of which had a<jats:italic>P<\/jats:italic>value for the association less than<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mn>1.0<\/mml:mn><mml:mo>\u00d7<\/mml:mo><mml:msup><mml:mrow><mml:mn>10<\/mml:mn><\/mml:mrow><mml:mrow><mml:mo>\u2212<\/mml:mo><mml:mn>5<\/mml:mn><\/mml:mrow><\/mml:msup><\/mml:math>and 603 (84.9%) of which had an odds ratio &gt; 5.0.

The three novel associations with the strongest temporal component were cardiac dysrhythmia, pulmonary eosinophilia, and volume depletion disorder.<jats:italic>Conclusion<\/jats:italic>. We identified novel associations with Charcot foot in the context of pathogenesis models that include neurotrophic, neurovascular, and microtraumatic factors mediated through inflammatory cytokines. Future work should focus on confirmatory analyses. These novel areas of investigation could lead to prevention or earlier diagnosis.<\/jats:p>","DOI":"10.1155\/2014\/214353","type":"journal-article","created":{"date-parts":[[2014,4,27]],"date-time":"2014-04-27T21:01:21Z","timestamp":1398632481000},"page":"1-13","source":"Crossref","is-referenced-by-count":28,"title":["Data Mining for Identifying Novel Associations and Temporal Relationships with Charcot Foot"],"prefix":"10.1155","volume":"2014","author":[{"given":"Michael E.","family":"Munson","sequence":"first","affiliation":[{"name":"Division of Metabolism, Endocrinology and Diabetes, Department of Internal Medicine, University of Michigan Medical School, 24 Frank Lloyd Wright Drive, Lobby C, Suite 1300, Ann Arbor, MI 48106, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James S.","family":"Wrobel","sequence":"additional","affiliation":[{"name":"Division of Metabolism, Endocrinology and Diabetes, Department of Internal Medicine, University of Michigan Medical School, 24 Frank Lloyd Wright Drive, Lobby C, Suite 1300, Ann Arbor, MI 48106, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Crystal M.","family":"Holmes","sequence":"additional","affiliation":[{"name":"Division of Metabolism, Endocrinology and Diabetes, Department of Internal Medicine, University of Michigan Medical School, 24 Frank Lloyd Wright Drive, Lobby C, Suite 1300, Ann Arbor, MI 48106, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Hanauer","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Michigan Medical School, 5312 CC, SPC 5940, 1500 E.
