At the time of examination such additional information as
could be obtained was noted, and is summarised with respect to
cases of visible thyroid enlargement under the following headings:—
Family History of Goitre.—Among the males there was a
history of goitre occurring in one or more members of the family in
four instances; in two instances the mother had or had had goitre;
in one case the mother and grandmother had been affected, and
in one case the mother and an. aunt.
Among the females there was a family history of goitre in
eight cases. The mother had been affected in four cases, a sister
in three cases and a great-aunt in the remaining case. Of these
cases a mother and two sisters had been affected in one instance
and in another instance the mother and the mother's cousin.
Relation to Menstruation.—Of the 14 girls affected, two only
had commenced to menstruate. This fact may have been due
to the routine examination occurring at an age that usually precedes
menstruation, so that a connection between the goitre and menstruation
could hardly be presumed.
Influence of Locality.—With three exceptions all cases had
always lived in London; and of the 16 cases, 13 had spent all their
lives in Ealing, so that no opinion can be expressed as to the influence
of locality on their occurrence.
