Unusual deaths associated with polyphagia.
Perversion of appetite may be manifest in either qualitative (pica), quantitative (polyphagia), or combined derangements of eating. Ingested materials are capable of serving as dangerous physical agents through interference with normal cardiac and/or respiratory function. Since the mechanisms of injury are similar to those that might occur as a result of violence or serious natural disease, a thorough investigation of the history and circumstances immediately preceding the final event is warranted in addition to a complete autopsy. Three cases of asphyxia of unusual etiology are presented along with a rationale regarding the mechanisms believed to be involved. In case 1, sudden subdiaphragmatic viscus expansion with resultant lung volume displacement and impediment of venous return from the lower half of the body are believed to have been operative. In cases 2 and 3, both asphyxial loci are infraglottic. The common denominator in all of these fatalities is the physical impairment of vital air exchange as a complication of an abnormal eating pattern.
