The total is greater than 422 because some descriptors occur in more
than one category.

Tree Revisions
For 2010 DeCS/MeSH, the
Category B (Organisms Tree) was reorganized to include specific taxonomic
descriptors for the third domain of life (Eukaryota). The descriptor
Protozoa, formerly under Invertebrates, was deleted because it has become
an outmoded phylogenetic concept. The vast majority of new descriptors
treed under Eukaryota comprise most of the organisms that were previously
treed under the old Protozoa.
The 20th century classification
of Protozoa emphasized modes of nutrition and locomotion; 21st century
classification is based on ultrastructure, biochemistry, and genetics. Most
of the organism descriptors that were treed under Protozoa are now treed
under Eukaryota, some under different taxonomic names. Note these organisms
are no longer treed under Animals and will not get the check tag Animals;
they are simply eukaryotes. Common usage of the word "protozoan"
still exists in the literature, though it is diminishing; for now we are
going to retain the other DeCS/MeSH descriptors with the word
"Protozoan." Thus the headings Protozoan Infections, Protozoan
Genes, and Protozoan Proteins, etc. have not changed.
For more detailed information
on these changes see 2010 MeSH® Category B Restructuring and MEDLINE® Data Changes — 2010.
H1N1 Virus
Influenza A Virus, H1N1 Subtype for the causative agent of what is
colloquially called "swine flu." It has entry terms H1N1 Virus
and Swine-Origin Influenza A H1N1 Virus. The disease coordinate for H1N1 in
humans is Influenza, Human. There are no references to "swine
flu" in DeCS/MeSH due to its ambiguous meaning (analogous to
"bird flu"). For more indexing details, see 2009 H1N1 Flu ("Swine Flu") Terminology.
Rare Diseases
Under an agreement with the NIH Office of Rare Diseases and
Research (ORDR), the list of rare disease terms maintained by that office
is being merged into the MeSH vocabulary. During the initial review process
of 10,379 ORDR terms, 1,332 ORDR terms were deleted because they were
abbreviations of fewer than five letters and therefore would have created
ambiguity if included in MeSH. A total of 274 ORDR terms were merged with
existing descriptors in DeCS/MeSH 2010. This increase is in addition to the
440 ORDR terms that were identified as being already in DeCS/MeSH 2010
descriptors. An additional 372 ORDR terms were identified during this
review process to be merged with MeSH 2011 descriptors. The remainder are
targeted to be Supplementary Concept Records (Class 3) in MeSH 2011. Each
of these rare disease SCR records will be mapped to (Heading Mapped to) at
least one current MeSH disease term to help future searches and indexing.
For example, ORDR
disease term Myotonia Congenita matches the existing DeCS/MeSH descriptor
Myotonia Congenita (D009224). The ORDR related term Thomsen Disease is an
alternative (or entry) term for Myotonia Congenita. See Figure 1; note the ORDR terms are
identified by the label Thesaurus with a value of ORD (2010). This
particular concept will have additional edits targeted for the 2011 MeSH.
