XXXX and parenteral injections; a review of recent literature.

@entity1 @entity66 @entity3328 @entity912
Data presented in the literature as to the relationship of @entity3328 and recent prior injections include several aspects. the coincidence of @entity912 in the same site as a recent injection has been considered the most definitive evidence. The fact of an inordinately large number of cases of @entity912 of an arm where a recent previous antigen injection was recorded offered less specific corroboration. The larger number of cases among @entity1 who had had an injection in the month preceding onset than among @entity1 with injections in more distant months was noted. This observation was supported when similar information was obtained in a comparison of injection histories for @entity1 who had the disease with the histories of @entity1 who did not have it. The interval between injection and onset among @entity1 who had the disease within a month of injection suggested something other than chance relationship. There is limited information indicating increased severity of @entity912 in the injected limb. Evidence is divided on whether or not there is more @entity66 among @entity1 with recent injections. Similarly, the evidence is no more than suggestive with regard to increased severity of @entity66 . The mechanism or nature of such a phenomenon is unexplained. However, as Anderson and Skaar said, "considerable attention must be attached to the fact of uniformity of results in a series of independent observations even though each may be small."
