PyMedTermino (Medical Terminologies for Python) is a Python module for easy access to the main medical terminologies in Python, including SNOMED CT, ICD10, MedDRA, UMLS and VCM icons.
PyMedTermino is available under the GNU LGPL licence, and it has been created by Jean-Baptiste Lamy, LIMICS, Paris 13 University, Sorbonne Paris Cité, INSERM UMRS 1142, Paris 6 University 74 rue Marcel Cachin 93017 Bobigny, France
This module includes Pymedtermino’s global parameters, the base classes for terminology-specific modules, and utility classes.
the directory where SQLite3 database files containing terminologies are located. Default : PyMedTermino directory.
the default language used for terms, when several translations are available. If the desired language is not available, it defaults to English.
Warning
this parameter must be set BEFORE loading terminologies. Default : “en” (English).
if True, concepts tagged as suppressed or depreciated in terminologies are skipped.
if True, terms (=translations) tagged as suppressed or depreciated in terminologies are skipped.
if True, relations tagged as suppressed or depreciated in terminologies are skipped.
The following function can get any concept from a “terminology:code” string:
Return a concept from a ‘full code’ including both terminology name and concept code (for example “icd10:I10”).
This module also defined the Terminology, Concept, Mapping classes that are used as base classes for the various terminologies.
Base class for all terminologies.
name of the terminology
Returns the root concepts in the terminology (=concepts without parents).
Searches for concepts whose terms match the given text (free-text search).
| Returns: | a list of concept. |
|---|
Retuns a generator for iterating over all concepts in the terminology.
Retuns a generator for iterating over all concepts in the terminology, each concept being iterated only once (for multiaxial terminologies).
Retuns the concept of the given code, or None if no such concept.
Retuns True if the terminology has a concept of the given code.
Retuns the concept of the given code; raise ValueError if it does not exist. Also available as Terminology[code] (i.e. Terminology.__getitem__).
Base class for all concepts, in any terminology.
the terminology this concept is extracted from.
the code of the concept
the preferred term (i.e. label) of the concept
the list of terms for this concept.
the list of parent concepts.
Note
Concept.parents is always a list, even for terminologies with single inheritance (like ICD10). This allows to write terminology-independent code.
the list of children concepts.
the list of the available relations for this concept. The available relations depend of the terminology, and is-a relations are not included (use parents and children attributes). Each relation corresponds to an attribute of the concept.
Returns the ‘full code’ for this concept, including both terminology name and concept code (for example “icd10:I10”).
Returns the preferred term for this concept, in the given language. Not supported by all terminology.
Returns all concept’s terms, in the given language. Not supported by all terminology.
Returns True if this concept is a child of the given concept (or if both concepts are the same).

Returns a generator for iterating over all ancestors of this concept. Each concept is only yielded once (useful for multiaxial terminologies).
Returns a generator for iterating over all ancestors of this concept, including the concept itself.

Returns a generator for iterating over all descendants of this concept.
Returns a generator for iterating over all descendants of this concept. Each concept is only yielded once (useful for multiaxial terminologies).
Returns a generator for iterating over all descendants of this concept, including the concept itself.
Returns a generator for iterating over all descendants of this concept, including the concept itself. Each concept is only yielded once (useful for multiaxial terminologies).
Base class for a mapping between two terminologies.
Maps the given concept(s) using this mapping.
Note
You only need this method if you have several mappings with the same origin and destination terminologies. In other situations, you should rather use concept(s) >> destination_terminology.
origin terminology for the mapping
destination terminology for the mapping
Registers the mapping as the default mapping between its origin and destination terminologies.
A set of concepts. The set can contain each concept only once, and it inherits from Python’s set the methods for computing intersection, union, difference, ..., of two sets.
Maps the set of concepts to the destination_terminology. See PyMedTermino tutorial for more info.

returns true if all concepts in the OTHER set are descendants of (at least) one of the concept in this set.
returns true if all concepts in this set are descendants of (at least) one of the concept in the OTHER set.
keeps only the most specific concepts, i.e. remove all concepts that are more general that another concept in the set.

PyMedtermino module for MedDRA.
Several concepts can share the same code in MedDRA. For example, a preferred term (PT) and a low-level term (LLT) can have the same code and label. In order to distinguish them, PyMedTermino does not use directly the MedDRA codes, but associates the term’s level with the code to obtain a unique code, for example “SOC_10019805” or “PT_10069435”.
