Landmark Papers in General Surgery will give surgeons, surgical trainees and other healthcare professionals an expert appraisal of key papers, and fast access to the evidence base behind current clinical practice in General Surgery. Each chapter draws together a fascinating selection of the most important clinical trials across every subspecialty within General Surgery, as selected and appraised by a panel of experts.

Organised according to a common format, each discussion offers a clear structure by which to appraise the medical literature. Following a background summary of each trial, experts discuss the impact of the research and critique the methods used, giving the reader rapid understanding of the paper's place within the wider field of research. This emphasis on the tools of critical appraisal is enhanced by an introductory chapter equipping the reader with the skills required to knowledgeably appraise a research paper.

For clinicians needing to keep abreast of the vast scope of medical research, this book will prove an interesting and timesaving resource, but it will also appeal to allied health professionals keen to improve the depth of their understanding of surgery. By bringing together the evidence base with expert guidance on critical appraisal, higher surgical trainees preparing for the academic and specialty sections of the FRCS exit examination will also find the text invaluable as a means of consolidating and nuancing their knowledge.

Concreto è il timore secondo cui entro poco più di un ventennio si giungerà a perdere quasi il 20% delle specie animali e vegetali che popolano il nostro pianeta: questa l'implacabile sintesi numerica del problema dell'estinzione, una minaccia che, lungi dall'interessare solo gli animali e gli ambienti in cui essi vivono, non può che coinvolgere, in ultima analisi, anche l'uomo. Attraverso carte, grafici e fotografie il volume conduce proprio alla scoperta di una simile minaccia, tracciando un'esauriente profilo delle specie ormai perdute o di quelle semplicemente in pericolo.
