The 4th edition represents a major revision of The Medical Word Book. Most of the reviews on this site are for the 3rd edition. The 4th edition (1500 pages) is still organized by specialty, with words appearing in more than one section if they apply to more than one specialty. The General Surgical Terms section contains primarily surgical hardware. Other surgical terms, like titles of operations, appear in the appropriate specialty section. The Drugs and Chemistry section has been removed, but the Dentistry section has been restored and updated, and a new section, Oncology and Hematology has been added. Neurology and Psychiatry have been separated, and other specialty sections have been expanded and the titles changed. See the table of contents which has changed substantially. Designed by transcriptionists for transcriptionists, Sloane's Medical Word Book is a must-have tool for anyone creating medical documents. Coverage of anatomy and general medical terminology as well as 18 medical specialties. Both phonetic and correct spellings of words are listed alphabetically for rapid access. 16 pages of full-color anatomy plates. Brand-new sections on Dentistry and Oncology and Hematology. Previous entries reviewed and thousands added to reflect current medical practice. Context clues have been added, cross-references are clearer, and numerous terms have been recategorized.
