The impact on database searching arising from inconsistency in the nomenclature of parasitic diseases.
The existing usage of disease names formed from the name of the parasite taxon is characterised by marked heterogeneity. This is largely due to the fact that, for coining disease names, four different suffixes, '-osis', '-iosis', '-asis' and '-iasis', are being used inconsistently. The result is that alternative terms are in use for naming the same disease, e.g. trypanosomosis and trypanosomiasis, fasciolosis and fascioliasis, ascariosis and ascariasis. Inspite of the SNOAPAD/SNOPAD guideline (1988) which proposed the principles of a uniform and standard disease nomenclature, the actual usage depends largely on tradition, educational imprinting and personal preferences, showing great variation. By using alternative disease names as search terms the author investigates in four databases the impact of nomenclatural heterogeneity on information storage and retrieval. It is evident that the existence of alternative disease names in parasitology markedly interferes with the efficacy of online data retrieval. The value of a disease name as a search term was shown to be greatly different in various databases. Until we have to coexist with an inconsistent disease terminology we need to adopt specially structured database-search techniques to ensure a proper level of precision in searching. Such possible techniques are considered.
