The total is greater

Rare Diseases
MeSH continued the work begun in 2010 of merging the list of rare
disease terms maintained by the Office of Rare Diseases Research (ORDR)
into the MeSH vocabulary. The rare disease terms that matched existing MeSH
descriptors were merged with those MeSH descriptors. The remainder were
introduced as Supplementary Concept Records (Class 3) in MeSH 2011.
As with
all SCRs, each of these rare disease SCR terms were mapped to
("Heading Mapped to") at least one current MeSH disease term to
help searching and indexing. For example, Snyder Robinson Syndrome is a new
disease SCR that is mapped to the MeSH descriptor Mental Retardation,
X-Linked. Both of these terms will appear in a MEDLINE citation if the SCR
is assigned by the indexer.
Because
rare diseases are defined as having a prevalence of fewer than 200,000
affected individuals in the United
States they traditionally received less
attention and are sometimes called orphan diseases. Having these terms
available for indexing purposes will enhance a more precise retrieval of
the rare disease articles and contribute to their identification.
Algae
Taxonomically algae are polyphyletic and therefore the descriptor
Algae no longer easily fits into the MeSH trees. So for 2011 MeSH, the
descriptor Algae was deleted and its children distributed among the
appropriate eukaryotic trees. Compare the placement for Brown Algae:

Sex Disorders
Based on the updated classification and new nomenclature
recommendations put forth by the 2006 International Intersex Consensus
Conference1, the Disorders of Sex Development (previously Sex
Differentiation Disorders) trees and descriptors were revised and updated.

Homeopathy
In 2010
the Homeopathy category was revised in collaboration with the São Paulo
Association of Homeopathy and the Virtual Health Library in Homeopathy. As
a result, the 1944 concepts and their 2476 synonyms are now defined in
three languages, adding more information to these concepts. read more
