'Medicine transcends all barriers; it knows no frontiers, it respects all credos and, most importantly, it treats all human beings as equals. Despite the tremendous socio-economic inequalities that I encountered and experienced in each one of the four countries where I’ve lived and practised medicine (Peru, United States, Spain and the UK), I’ve always been proud to find that the Hippocratic Oath is unwavering and equally applied to all citizens. My identity never came from having a certain nationality, speaking a specific language or even from my family genealogy. It came (and still does) from the set of values that the medical profession professes and that I, as a doctor, hold close to my heart. These values are the building blocks of society; without them, everything else crumbles. My “nationality” is medicine and my allegiance is to the human race. The lives and the clinical cases in this book are all real and they tell the story of how the Hippocratic Oath prevails even in the most challenging conditions. They remind us that no matter how much adversity lies before us (poverty, socio-economic instability, lack of resources, etc.), with sufficient effort, creativity and perseverance, there is always light at the end of the tunnel. After all, altruism – the bedrock of medicine – is free of charge, independent of location and always available for anyone who’s willing to use it.'Dr Carlo Canepa
