Medical Database—version 6

Welcome to version 6 (v.6) of the Dictionary of Modern Medicine database (DMMD), a medical lexicon for physicians, med students and advanced health professionals. Version 6 is comprised of 9 subdatabases with 58,260 definitions, a number which makes it the 4th largest medical dictionary* and the largest free one (version 7 will have another 4,000 entries, primarily genes). To download and use v.6, follow the instructions on the bottom of this page. Version 5 was a Mac/iOS-only resource. Kent Hummel, our database mavin, is working on the Windows version, which will be released shortly.

*This project is growing at a rate of ± 18,000 terms/year with updates in bimonthly cycles. Because of a death in the family, v.6 will be delayed for a few weeks, giving Dr. Segen a chance to add more genes before releasing it. We expect to finish 2019 with over 75,000 entries…in the meantime, stay tuned. 

V.6 includes the following subdatabases:

  • MEDICAL ABBREVIATIONS & ACRONYMS (A&As) At nearly 22,000 entries, this is one of the largest and certainly the only physician-curated group of biomedical A&As available online. New material is added daily, obtained from professional literature ranging from peer-reviewed work to throwaway journals. 

  • GENES This data set has core information (location, function, associated diseases if known, aliases and, importantly, references linked to the Genecards and Uniprot databases) on over 14,000 genes of the 30,000+ genes recognised by the HUGO. We at believe that this will prove especially useful to our audience and look forward to your feedback.

  • HEREDITARY DISEASES & SYNDROMES This data set has core information (patterns of heredity, clinical findings, causative genes and proteins, aliases and references linked to the OMIM and Uniprot databases) on over 6,500 inherited conditions. As with the GENES subdatabase, we believe that this will prove useful to medical students and physicians alike.

  • BRITISH MEDICINE This data set contains nearly 4,500 entries, is based in large part on the author’s years spent in the UK, and reflects the differences between the US systems of reimbursement and partial coverage and the universal coverage and single party payment model that defines British medical practice.

  • ALTERNATIVE MEDICINE This data set defines over 3,500 terms germane to alternative and complementary practices. The author, a pathologist, views this “field” with the jaundiced eye of a skeptic, noting most alternative modalities remain unproven at best and dangerous at worst.

  • SEXOLOGY, SUICIDOLOGY The terminology found in these two data sets are self-explanatory. For each, the compiler was forced to sail between the Scylla of excess and the Charybdis of paucity. 

  • OLD/RETIRED TERMINOLOGY The 5,000+ terms in this data set answer, possibly for the first time in a medical lexicon, the question of what should we do with biomedical terminology at the end of its useful life? Most medical dictionaries hang on to the terms far too long, then without a whimper, remove the offending dinosaur from subsequent editions. We feel that those doing library research in older publications still need definitions of retired terminology, hence…

  • EVIDENCE-BASED MEDICINE This data set contains core definitions in what has become the central theme of medicine in the 21st century…that all forms of medical practice must be based on supportive evidence

We feel that the DMMD will become your “go-to” place for succinct definitions in the above areas. We’re releasing the DMMD free of charge, but ask that you register* so we can give you a ‘heads up’ when updates become available (version 7 is in the works; it will have ±2,000 more genes and a new data set—therapeutic monoclonals).

*Your particulars will not be shared with (annoying) third parties.

Version 6 can be downloaded directly to your Mac Under Construction; for iOS devices (iPhone, iPad), you’ll need to first download Filemaker Go For both formats, the user name is user; the password is user (they are case sensitive). 

The Windows formatted version is under development. Filemaker does not support Android devices. Once we procure sponsorship, the data will be accessible to all devices, as the public releases will be on a server

When you find a term of interest, you can either (1) copy and paste it into your notes or, if the definition is big, (2) email yourself the entire definition. And if that’s not enough, you can google it right from the page.

Best regards, JC Segen, MD,
