Criteria for evaluation of results after extensor tendon lesions are presented, which are easy to apply and based on angular measurements of active joint mobility. The scheme is analogous to the evaluation method for flexor tendon injuries published by Buck-Gramcko et al. in 1976 which is now widely used. A modification was necessary to treat the extension deficits more severely. A comparison is made to the evaluation method proposed by the Group of Erlangen, and both schemes are tested on 68 patients with extensor tendon injuries of different zones, various fingers and combinations. Lesions of the thumb require different criteria.

In comparison with the first statistics published in Goettingen 10 years ago the frequency of the arm oedema has increased from 33,5 to 45,3%. Most arm oedemas appear within the first observation year after the operation or irradiation. Severe arm oedemas appearing immediately after the operation or irradiation as well as at a later date after a prolonged interval without any troubles are generally combined with a lymphogenic formation of metastases. A comparison of the two periods shows a significant difference of degrees within the observed groups. During the first observation period from 1950 to 1962, the frequency of the severe oedema is 6% higher than during the observation period of 1963 to 1975.
Lymphograms have been performed on 775 urological patients. Our experience indicates a scheme for lymphography in this particular speciality. According to this, carcinomas of the bladder and kidney are a relative indication for lymphography, whereas carcinomas of the scrotum, penis and prostate present an absolute indication. Fiftyseven lymphograms have been performed on 52 patients with carcinoma of the penis. In one patient the examination was carried out twice in one year, in another, three times and a third patient had three lymphograms over a period of six years. Most patients were aged 60 to 69 years, average age 61.48 years. Agreement between the histological and lymphographic findings was observed in 26 out of 34 patients treated surgically (76.5%).
Following Egan (2), Gros et al. (8,9), Ingleby and Gershon-Cohen (11) and Witten (18) the appearances of mammograms were divided into four groups: I. Dense, II. Atrophic, III. Shrunken-fibrous and IV. Cotton-wool, diffuse. In young women up to the age of 30 a dense structure is the most common (74.8%). On the basis of available statistics, the use of mammography for routine detection of carcinoma of the breast cannot be justified in women under the age of 30; not only is this condition very rare at this age, but proper evaluation of the relevant signs is only possible in one woman in four because of the structure of the breast. On the other hand, if there is any suspicion of the presence of a carcinoma, then mammography should be carried out and additional forms of examination, such as thermography and xerography, should not be neglected.
