[Importance of supplementary testing for diagnostic proficiency at the bedside].

Two patients are described who were originally published in Reports of medical cases (1827; 1831) by Richard Bright. The first patient suffered from haematuria and oedema (dropsy) and died after acute epiglottitis. At autopsy the kidneys were swollen and haemorrhagic (acute glomerulonephritis in present terms). The second patient died after two episodes of acute headache and decreased consciousness. At autopsy an aneurysmatic dilatation of a brain artery was found. Today the diagnosis of acute glomerulonephritis or subarachnoid haemorrhage would have been made from the history and physical examination, and newly developed laboratory and histological techniques would have been helpful in securing it. But even nowadays, clinical skills are still continually expanding by feedback from new diagnostic techniques.
