APRIL FOOL'S! 
Alert readers the world over will have recognised that our item entitled "Hormone treatment promises to shorten time of pregnancy, yielding cost savings, productivity gains" – though no doubt tempting to many in positions of power – was in fact an April fool's prank.

3 Decades of "fishy business" in April
The traditional April prank by Prescrire's editors serves as an annual "booster shot" to remind us all that in the serious business of medical information, it pays to exercise critical judgement at all times.

In April 1983 Prescrire's "special correspondent" revealed to enthralled readers the enormous interest of protryptophane in the treatment of acute senility... And ever since, the experiment has been repeated yearly in La revue Prescrire's April issue.

In 2003 Prescrire's "April fish" (as the seasonal pranks are known in France) even made it into the English edition, Prescrire International. It's included below, in a sampling of Prescrire's yearly "Poissons d'avril".
