摘要:

Comment is made concerning particular aspects of the arteriographic signs of malignancy.An account is given of arteriography carried out in 40 cases of neoplasm of bone and soft tissues of which 33 were primary tumours of bone.Various conclusions are drawn concerning the value of this type of investigation. It is emphasised that a normal arteriogram does not exclude the presence of malignant change, and that caution must be exercised in drawing rigid conclusions from the arteriographic signs alone.Special reference is made to arteriography following deep X-ray therapy and reasons are given as to why this is considered a procedure without value in such circumstances.Amputated specimens were injected and compared within vivoarteriograms and the histological picture.

摘要:

1. An account is given of an autoradiographic method of measuring radiation dose-rate in bone following uptake of90Sr.2. The dose-rate pattern in the upper half of the tibia of young and old rabbits given a single injection of90Sr or fed daily pellets containing90Sr is described.3. The ratios maximum dose-rate/average dose-rate (non-uniformity factor) and maximum dose-rate/minimum dose-rate have been measured. For rabbits fed90Sr from the age of five to eight weeks the greatest values of these ratios are 3·1 and 4 respectively. For rabbits given a single injection at the age of five to eight weeks they are 6 and about 70. For rabbits given a single injection aged one year and more they are 7 and 14.4. It is concluded that the non-uniformity of radiation dose-rate for90Sr as determined by the ratio maximum dose rate/average dose-rate is never great for the long bones. The greatest value found was 7.

摘要:

Papers on new developments in the borderline of physics with biology and medicine are so numerous, and the multiplication of journals so confusing, that the interested non-specialist is becoming increasingly dependent on reviews written by experts if he is to keep himself aware of even the broadest outlines of what is going on in these fields.

摘要:

The results of an investigation into the use of theoretical models for estimating the proportion, “c”, of patients cured after treatment for carcinoma of the breast are presented. The difficulties of using a lognormal or an exponential model are discussed, and it is suggested that a better method of estimating “c” is to assume that the probability of dying from cancer decreases exponentially with increasing time after treatment. The “Extrapolated Actuarial” model, based on this assumption, is shown to be a good fit to some known survival data having a 20-year follow up, and at the same time the computations involved in its application are relatively simple. Full details are given of the method of calculation.

摘要:

The clinical and radiological features of Ehlers-Danlos syndrome, as found in a 25-year-old woman and in her 59-year-old mother, are briefly reported. Several unusual features are described.The radiological finding of the typical oval subcutaneous calcified nodules may be the first clue to the correct diagnosis, particularly in the clinically less obvious cases.

摘要:

Attention is called to the existence of changes in the position of the cervical spinal cord dependent on the position of the body. The method of measuring the extent of these shifts is described. In the group of 120 “normal” individuals the extent of the movements of the spinal cord was measured. The relations of these shifts to the different spinal segments, to the antero-posterior diameter of the spinal canal and to the changes in the shape of the cervical spine are discussed.

摘要:

The techniques used at the Royal Marsden Hospital for the intracavitary irradiation of the bladder with radioactive fluids are reviewed. A modification of one of these techniques introduced in an attempt to lower the incidence of irradiation-produced damage is described. A solution of calcium bromide 82 contained in a latex rubber balloon is used to treat the bladder mucosa continuously for 96 hours, a surface γ dose of 4,200 rads and β dose of 1,000 rads being delivered. The dose-rates are at least ten times less than those used in previous techniques.The results from this treatment for a series of 20 patients are compared with those from earlier techniques. No high dose effects were observed and complete disappearance of all tumours occurred after three months in nine cases. Survival times for the different treatment techniques are tabulated.The method of calculating the radiation dose to the bladder mucosa is outlined.(For acknowledgments and references see following paper.)
