Radioterapie in prostaatkarsinoom

Perusal of the literature reveals the limited value of surgery in primary prostatic carcinoma, and the dangers of oestrogen therapy. Radiotherapy has not been used extensively. We have treated 62 patients with prostatic carcinoma by means of telecobalt therapy. We managed to obtain biopsy specimens in 38 of these patients several months after completion of therapy. In 21 patients the biopsies proved to be negative. Neither histological differentiation nor previous oestrogenic therapy seem to influence the radiosensitivity of prostatic carcinoma. A radical dose is required to cure these cancers. Five-year survivals have been achieved. We strongly advise the use of radiation therapy in patients with restricted, though inoperable, prostatic carcinoma. Purely palliative therapy, e.g. oestrogen or seminectomy should be withheld until the presence of metastases has been proved.S. Afr. Med. J., 48, 321 (1974)

Orthodontics : a review

Orthodontics is a branch of dentistry which is concerned with the study of the growth of the craniofacial complex and the occlusion of teeth. It implies the diagnosis, prevention and treatment of abnormalities in these structures. It has been found that only about 25 % of the population has normal occlusions and that 75 % have malocclusions, whether in a lighter or more serious grade. As malocclusion is not a disease, but a result of the variability between the growth and development of dental and craniofacial structures, we do not expect its occurence to decrease. The training of orthodontists only started taking shape seriously after the second world war and has already reached saturation point in certain parts of America and Europe. Here in South Africa though, we still have a shortage which will still last for some time. Education in orthodontics takes place on an undergraduate as well as 'n postgraduate level with research as part of the post-graduate training. Being only a branch of dentistry, good co-operation between orthodontics and the other branches is encouraged.http://explore.up.ac.za/record=b133589
