Dr. Z. Zubrzycki reports as follows on the use of the Dermo-jet:-
"A new method of tuberculin testing and BCG vaccination was introduced in June 1969. Instead of
a syringe and needle a jet-injection apparatus (demo-jet) is used which makes intradermal injection
by means of a pressurised jet. It is rapid in use and by elimination of syringes and needles less
costly. After a period of trial certain short-comings of this technique became apparent, among them
the under-dosage of the vaccine delivered by demo-jet. For this reason the BCG vaccination is at
present carried out by the old method of syringe and needle, whereas the demo-jet is used for skin
testing.
The jet-injection is a new invention and provided its technical efficiency is guaranteed it will be
valuable as an instrument in immunisation programmes."
Cases of Tuberculosis occurring in Teachers or Pupils
During 1969, an investigation was carried out on the advice of the Chest Physician at one school
where a case of tuberculosis had occurred amongst the pupils.
The results were as follows:-
Heaf Tests of immediate contacts 31
Referred to Chest Clinic for further investigation 5
No additional case was discovered at the school.

There are now two special clinic sessions held each week at Weston Park and Lordship Lane Medical
Centres to deal with plantar warts, conducted by Dr. Shah, a medical officer who has had special
training in their treatment.
Dr. Shah reports as follows on the work at these clinics during the year:-
"Special clinics for the treatment of warts amongst school children started in the year 1969. Two
sessions in a week at two different clinics are allocated for the treatment. Almost all kinds of
warts except the facial and those that are situated on difficult and dangerous areas are treated in
these wart clinics. The line of treatment depends on the size, situation and the number of warts.
Treatment of choice is by electrocautery as it gives satisfactory results and complete healing takes
place usually in a week. The area around the wart is cleaned and painted with acriflavin. Local
anaesthetic 2% Xylocain is infiltrated. The wart is then either cut off with sterilised scissors or
excised with knife. After scooping the area with a scoop to remove the indurated tissue, it is
cauterised. It is kept covered with a dressing for one week, during which time complete healing
takes place.
The warts of small and unco¬operative children are treated with either chlorosal paste or collodion
salicylic acid.
For the treatment with electrocautery, the presence of a parent or guardian is essential."
