List the clinical signs on examination that would support the diagnosis of infective
endocarditis in a patient with fever and a new murmur.
Janeway lesions (small, non-tender erythematous or haemorrhagic macular or nodular lesions on the
palms or soles)
Roth spots (retinal haemorrhages with pale or white centres
Oslers nodes (painful, red raised lesions found on the hands and feet)
An excellent review article form 2009 lists the following clinical features:
The abovementioned article has a table (Table 3) which lists these manifestations according to their prevalence among a large patient cohort. The emphasis of the article is on endocarditis "in the 21st century", implying that the endocarditis of the previous centuries was substantially different. This is certainly true. One need only refer to the 1885 Gulstonian Lectures by William Osler to see what infective endocarditis looked like in the pre-antibiotic era (in short, it was uniformly fatal). For a relatively recent 20th century perspective, one can turn to a 1983 review of the state-of-the art diagnosis and therapy for the previous 25 years.
