    Acute nongonococcal urethritis (NGU) is one of the commonest sexually transmitted infections affecting man and woman. The diagnosis of NGU has traditionally required microscopic evidence of urethritis.

In view of this, we were interested in the paper by Orellano et al. 1 in which they indicate that this may be a bigger problem than otherwise thought...
