Every april 30, we celebrate Teacher’s day, the date on wich we remember with special affection those who through their vision of theaching, their wisdom and love of the profession, infected us with the desire of constantly improve and nourished our scientific curiosity, pouring all of it self to form a generation of surgeons with a critical sense, humanist and the art of surgery to serve those who needed.

Great masters of paraguayan surgery have printed their experiences in our journal, and they have enriched us in our congresses, but most importantly, they have walk by our side in the day to day life in the hospital. I even dare to say that some fortunate people have had the honor of being called friends by these brilliant leaders of the teaching.

But also, they have left us two duties; the first for ourselves, wich is to try to equal them or maybe, even be better, a difficult task that can be carry out with the same sacrificed they did; and the second equally important to the previous one, which is to transmit to the youngest surgeons what was taught by them and learned from us, the scientific and moral quality, which should be the pillars to consolidate our surgical society.

This issue of our journal is dedicated to them, to our teachers, to those who are no longer here, and to those who continue to bet on a human and scientific teaching quality.

Congratulations Masters!

The editor.
