There is no clubbing, but tar staining is present on the fingers and nails of the right hand. On auscultation of the heart there is a grade 3/6 ejection systolic murmur radiating to the carotids and a soft early diastolic murmur audible at the lower left sternal edge. The urine looked clear but routine stick test- ing showed a trace of blood and on urine microscopy there were some red cells. The findings of mixed aortic valve disease, microscopic haematuria, malaise and fever (probable with the night sweats) make infective endocarditis a likely diagnosis. In the elderly, infective endocarditis may be an insidious illness and should be considered in any patient who has murmurs and fever or any other change in the cardiac signs or symptoms. The other classical findings of splenomegaly, splinter haemor- rhages, clubbing, Osler’s nodes, Janeway lesions and Roth’s spots are often absent. Precipitating events such as dental treatment or other sources of bacteraemia may not be evident in the history. When there is a fever or other evidence of infection in the presence of valve disease, infective endocarditis must always be considered although in practice other unre- lated infections are more common. Other infections such as tuberculosis or abscess are possible or an underlying lymphoma or other malignancy. The most important investigations would be: • blood cultures performed before any antibiotics are given. In this case three blood cul- tures grew Streptococcus viridans • echocardiogram which showed a thickened bicuspid aortic valve, a common congeni- tal abnormality predisposing to significant functional valve disturbance in middle and old age.

Describe how the context in which we learn information can influence our memory of that information. We want to remember the name of the new boy in the class, the name of the movie we saw last week, and the material for our upcoming psychology test. Psychological research has produced a great deal of knowledge about long-term memory, and this research can be useful as you try to learn and remember new material (see Table 8. In this section we will consider this question in terms of the types of processing that we do on the information we want to remember. To be successful, the information that we want to remember must be encoded and stored, and then retrieved. Information is learned better when it is Make use of the studied in shorter periods spaced over spacing effect. Rely on We can continue to learn even after we Keep studying, even if you think you already have it down.
