Extracardiac manifestations of infective endocarditis and their historical descriptions.
In his landmark "Gulstonian Lectures on Malignant Endocarditis," published in 1885, William Osler commented, "Few diseases present greater difficulties in the way of diagnosis than malignant endocarditis, difficulties which in many cases are practically insurmountable." At that time, the fields of microbiology and blood cultures were in their infancy, and the diagnosis was made premortem in just half the patients with the condition. After Osler's report, extracardiac physical findings became essential clues to earlier diagnosis. Today, infective endocarditis is most commonly suggested from the history and often clinched by an echocardiogram and blood cultures. Although prized physical manifestations are much less frequent now, they still do occur and may be an invaluable clue that leads to earlier, more effective treatment. The investigators review these extracardiac findings along with their historical descriptions: splinter hemorrhages, emboli, Osler's nodes, Janeway and Bowman lesions of the eye, Roth spots, petechiae, and clubbing.
