The close association of the exudative and neuropathic diatheses suggests a causal relationship. The frequent anaphylactic nature of the former1 would seem to point toward a similar cause in the latter. It is my purpose in this paper to discuss certain nervous manifestations in infants and children from the standpoint of anaphylactic cause.
It is hardly necessary to call attention to the frequent occurrence of the exudative and neuropathic diatheses in the same individual. All observers recognize the common association. However, it seems to have been generally held that this relationship is nothing more than accidental. Czerny considered it so.2 He felt that the almost universal presence of the neuropathic diathesis in one or both parents of children with the exudative diathesis led, as a natural result, to the neurotic child. The degree to which the infant was affected by this nervous environment determined, to a certain extent,
