51Cr-bleomycin in the diagnosis of tumours of the chest.

51Cr-bleomycin was used for the scintigraphic diagnosis of primary and secondary tumours of the thorax. The study was based on observations in 104 patients. The scintigraphy was performed using a gamma camera coupled to an on-line computer. Active lesions were scored using a semiquantitative scale of scores 0 to 5. Images were subdivided into 222 regions considered. In 72 of these, the presence of disease was diagnosed (64 malignant, 8 non-malignant) and 150 regions were classified as free from disease. At the decision threshold of score 2, over-all sensitivity and specificity of the scintigraphic detection of malignant tumours amounted to 97 and 79%, respectively. Inflammatory changes displayed some detectable accumulation of 51Cr-bleomycin but scores attributed to these lesions did not exceed the value of 2.

[X-ray changes in the osteoarticular system in sawyers].

X-ray test of the osteo-articular system of upper limbs was carried out on 1231 saweyers and 272 controls as well as 50 intellectuals. Three x-ray tests were carried out on 207 sawyers and on a control group of 95 workers, to assess the progression of osseous changes. The same types od changes were found in sawyers and control group workers; besides similar frequency in the examined parts of the upper limb was found in them. The most frequent changes are: osseous cyst, osteoporosis degenerative-deformative changes and calcar of the ulnar. The greatest amounts of changes were observed in the bones and joints of the hand and next in elbow joint and acromioclavicular joint. It was observed that amoungst the sawyers and the control group workers, the greatest amounts of changes occur after 2 years of work. Progression of osseous changes after 3-4 years of work was observed in 30,9% sawyers and 12,6% control group workers.
