§ Mr. HARRISasked the Minister of Health whether his Department has had any inquiry into the subject of phototherapy; whether he has any information as to the proof of actual physical benefits in curing to the recipient of artificial-light treatment as administered by the ultra-violet lamp; and whether he will consider holding an inquiry into the efficacy of light treatment generally, especially in welfare centres?
§ Mr. GREENWOODSpecial inquiries have been made during recent years by medical officers of my Department into the application of phototherapy (including artificial-light) to the treatment of disease, and the results have been published in the annual Reports of the Chief Medical Officer. These observations are being continued, and I do not see any necessity for a further inquiry. As regards the second part of the question, I am advised that the best results of this form of treatment appear to have been obtained in cases of rickets and, of certain forms of non-pulmonary tuberculosis.
