In trying to keep up to date with the literature, the medical journal reader will turn to original articles. Here he will find reports on large-scale studies either confirming or discrediting accepted ideas and practices. If lucky, he may even strike a new observation, possibly one in the nature of a breakthrough.
When in a less ambitious mood, our reader will glimpse through the letters to the editor. There he will find a mix of useful tips, whether based on anecdotal evidence or derived from modest preliminary studies. These tips may suggest improvements, however small, in diagnostic or therapeutic techniques; they may provide new or revive old clues to prognosis; occasionally they may even suggest a lifesaving maneuver.
Such a mélange of tips can be found in any letters to the editor section of reputable medical journals. For instance, browsing through the letters of a randomly selected issue of the
