• Validating the 5Fs mnemonic for cholelithiasis: time to include family history.

      Bass, Gary; Gilani, S Nadia S; Walsh, Thomas N (2013-11)
      The time-honoured mnemonic of '5Fs' is a reminder to students that patients with upper abdominal pain and who conform to a profile of 'fair, fat, female, fertile and forty' are likely to have cholelithiasis. We feel, however, that a most important 'F'-that for 'family history'-is overlooked and should be introduced to enhance the value of a useful aide memoire.
