- Koilonychia
What should you look for in the face of a patient when performing a cardiovascular examination?
- Mallar flush

- Corneal arcus
- Central cyanosis
What should the normal capillary refill time be?
Less than 2 seconds
What appearence does malar flush give?
A high colour over the cheekbones, with a bluish tinge caused by reduced oxygen in the blood
What is the underlying cause of malar flush?
Considered to be a sign of mitral valve disease which often follows rheumatic fever (however all but extinct in UK) so it is likely to be something else)

> 5 g/dL
What does pale conjunctiva indicate?
Anaemia
What is the characteristic skin lesion of systemic lupus erythematosus (SLE) referred to as?
A butterfly rash
What does Koilonchychia look like in a patient?
Abnormality of the nails that is also called spoon-shaped (concave) nails
What is Koilonchychia recognised as a manifestation of?
Chronic iron deficiency
What is the most common cause of clubbing?
Lung cancer
What can cause clubbing?
Reduced oxygen in the blood as a result of heart and lung diseases.
Congenital cyanotic heart disease, chronic lung infections, interstitial lung disease, coeliac disease. cirrhosis of the liver, overactive thyroid, infective endocarditis, other types of cancer (e.g liver, GI, Hodgkin lymphoma).
What percentage of patients with infective endocarditis fever?
90%
What percentage of patients with infective endocarditis have a heart murmur?
85%
What are splinter haemorrhages?
Tiny blood spots underneath the nail. A result of infective endocarditis
What are osler’s nodes?
Painful, red, raised lesions found on the hands and feet. Associated with infective endocarditis. Immunological reaction to the infective emboli.
What are Janeway lesions?
More common on palms. little bleeds on the skin. Indicative of infective endocarditis.
What are Roth’s spots?
A red spot (caused by haemorrhage) with a characteristic pale white center. Most commonly seen in infective endocarditis.
What is the pale white centre of a Roth’s (Litten) spot a result of?
Represents fibrin-platelet plugs
