Fetal or neonatal effect of X

PBR

• There are quite a few ICD 11 concepts of this format:
  Fetal or neonatal effect of fetal blood sampling

  Fetal or neonatal effect of maternal malnutrition

  Fetal or neonatal effect of maternal periodontal disease

  They mean findings in the fetus or newborn due to conditions associated with the mother. Existing related concepts in SCT subordinate to Fetal damage from disease in the mother (disorder) SCTID: 609429008 e.g.

  Fetal damage from maternal rubella (disorder) SCTID: 609434007

  - the SCT concept is modelled the following way >

  Occurrence → Fetal period

  Causative agent → Rubella virus

  Associated with → Viral disease

  I am unaware of existing rules concerning modelling these concepts and they are in effect combined disorders in different individuals - using the above example it would be tempting to express it in the alternative way:

  Disease

  Occurrence → Fetal period

  Causative agent → Rubella virus

  Due to→ Rubella

  IS_A Fetal damage from disease in the mother [SCTID: 609429008]

  But of course this fails to express the fact that the Rubella disease was present in the mother whilst pregnant with fetus - although one could argue that if the mother had rubella the fetus had it too - so the suggested model goes as far as it can.

See discussion below re. HTLV-1 and adult T-cell leukemia//lymphoma. Current model does not capture infection in mother passed to fetus.

HTLV-1 and adult T-cell leukemia//lymphoma

PBR

X following Y, X due to (and co-occurent) Y, X caused by Y

Feeling was that using causative agent would not capture the fact that transformation is a late effect of the infection as opposed to other HTLV-1 related diseases. Would use after HTLV-1 infection.
