For each 100 new cases and contacts examined at the Clinic
154 specimens of sputum were examined.
1938 shows a decrease in the number of examinations of sputa
made for General Practitioners. It is difficult to understand why
this simple test is not always made in any doubtful chest condition
X-Ray Work.
620 X-ray examinations were made during the year, an increase
of 73 over 1937. This is equivalent to 74.7 for every 100
new cases and contacts seen, and compares with a rate of 68.4 in
1937, 53.6 in 1936, 45.2 in 1935, 40.4 in 1934, and 30.4 in 1933
In addition a certain number of cases who have already been
examined at various Hospitals are referred to the Clinic.
The X-ray plant installed at Mayday Hospital has been
available for X-ray examinations of Dispensary cases, and during
the year most of the X-ray examinations were carried out at this
Hospital.
Tomography.
During the past year or two a new method of radiology has
been developed called tomography. By this method it is possible
to take X-ray films of the lungs, etc., in sections or slices at any
predetermined depth.
In Croydon we have been fortunate in having one of the first
tomographs in this country, which was devised by Dr. H. C. Colyer
through whose kindness 23 cases were examined by this method
in 1938.
Extra Nourishment.
Provision of special nourishment in the form of milk was
granted to 79 selected cases for varying periods during the year
and 50 cases were in receipt of extra nourishment at the end of the
in
year.
