The following annotated bibliography has been developed for the purpose of providing to primary care physicians a handy source of review articles and major studies in the the field of nephrology, hypertension, and fluid and electrolyte disorders. Almost all of the articles are review articles of clinical topics that would be of interest to the practicing physician. JAOA will be publishing additional annotated bibliographies in various fields of internal medicine over the next several months. The second in this series will appear in a forthcoming issue of THE JOURNAL.
