"Acute" @entity5636 at the 1930 Johannesburg Conference on XXXX and in its aftermath: Controversies over a distinct entity later recognized as silicoproteinosis.

BACKGROUND: Very rapidly progressive " @entity697 " was observed prior to the 1930 International Labour Office Conference on @entity5636 , but its clinical significance and pathologic relationship to classic @entity3440 caused @entity3673 were not settled. METHODS: Textual analysis of the 1930 Conference proceedings identified data relevant to rapidly progressive @entity5636 . Standard bibliographic searches identified relevant biomedical literature dating from before and after the Conference. RESULTS: The 1930 Johannesburg Conference contained descriptions of @entity697 , especially in the abrasive powders industry, but acute @entity3440 -related @entity358 did not conform to a three-stage disease model in @entity378 caused advanced disease, a model accepted at the Conference. Over following decades, additional reports appeared of rapidly progressive @entity5636 , unrelated to @entity378 . @entity5970 was identified only in 1958. CONCLUSIONS: Adoption by the 1930 Johannesburg Conference of a classification scheme into which acute rapidly progressive disease unrelated to @entity378 fitted poorly may have impeded the understanding of @entity697 and its importance.
