Haemophilia Associated with Normal Coagulation Time

Abstract

ADDENDUM.-Two years after completing its first tour, the Northamptonshire Mass Radiography Unit went round the county again.The final results of this survey are not yet available, but a preliminary inspection of the records suggests that the incidence of newly discovered active pul- monary tuberculosis among male boot and shoe operatives is now no higher than among men in other occupations.The exact significance of this finding cannot be appreciated until it is known how many of these men were examined for the first time; how many Were new entrants to the industry what type of case was discovered; and what was the age distribution of the population examined.It is, however, likely that boot and shoe factories in Northamptonshire are already reaping the benefits of having had a thorough comb- out of chronic carriers during 1945-6.
