The Incidence of Rickets in a London Hospital Out-patient Department.

There is wide difference of opinion as to the prevalence of rickets amolng the urban child population of Great Britain. This is, in part, attributable to the divergent standards of diagnosis accepted by various clinicians; on the one hand rickets is frequently diagnosedl because the child has sweating of the head or flabby muscles or is backward without any evidence of pathological change in the bones, and on the other, some practitioners are not prepared to diagnose rickets until there is gross bone dleformity.
