Quotes from MJA contributors in 2005

It is unusual to find mention of beavers’ living arrangements in a physiology journal but, according to Swain, there are similarities between beaver pond levels and blood glucose levels. A beaver must maintain a constant water level in its pond for the proper functioning of its lodge, just as we must maintain our blood glucose levels within a defined range to ensure, among other things, brain function.1 The beaver controls the water bed by changing outflow over the dam and inflow from the stream beds, just as insulin controls glucose leaving the blood and entering tissues, and, among other things, glucagon affects glucose release from the liver.

Analogy and metaphor may be figurative rather than scientific forms of communication but they can nevertheless help us, our students and our patients, to integrate new information by drawing on similarities with prior knowledge. Swain’s engaging beaver pond analogy of blood glucose control is a quiet and gentle one. As you will see in the following selections, this year’s MJA contributors have used a variety of analogies and metaphors (sometimes unwittingly) to try to get their point across. As well as creating a bridge to understanding, these devices inject unexpected and welcome humour into the generally dignified world of medical publishing.
