Basic Correlative Echocardiography Technique and Interpretation

time of the symposium. Thus this work represents a review of the field as it stood then, rather than a collection of original research, for which its format of rapid offset printing is usually reserved. So although the book is a useful single source, it is rather unhappily organized to serve as an introduction to frozen blood for the uninitiated. The most useful and novel contributions are the articles on post-transfusion hepatitis (by Shires, and by Barker and Gerety) and on the role of transfusion in renal transplant survival (by Opelz and Terasaki, and by Polesky). Many of the other manuscripts have an anecdotal rather than investigational flavor. On the other hand, Sloviter's historical essay is both fascinating and entertaining. The discussions are not particularly noteworthy, with the exception of occasional pearls such as the discussion of the difficult question of study design in transfusion effects on renal graft survival by Drs. Polesky and Terasaki. In short, the blood banker will find little new in this work and those looking for an introduction to the subject will find the format a modest obstacle. The book is probably most justifiable in terms of the excellence of several of its essays as reviews of the literature.
