[Diagnostic relevance of thermography in renal transplantation (author's transl)].

During a followup period of 18 months 75 renal transplant recipients were examined by thermography according to Tricoire. Thermography is a not invasive, quickly available and reproduceable method. Because of the high incidence of 85% exact diagnoses this investigation is a helpful additional test in kidney transplantation for evaluation of graft function as well as for diagnosis for evaluation of graft function as well as for diagnosis of pathological intrarenal or perirenal disorders. Thermography is especially recommendable for transplant patients, if postoperative haemodialysis is necessary. In these cases information can easily be obtained whether postoperative olig-anuria is caused by acute tubular necrosis or by primary insufficient vascularisation of the transplant.

Use of thermography in kidney transplantation: two year follow up study in 75 cases.

During a period of 24 months 75 renal transplant recipients were examined by thermography according to Tricoire. Thermography is a non-invasive, quickly available and reproducible method. Because of the 92% incidence of exact diagnosis this investigation is a helpful additional test in kidney transplantation for evaluation of graft function as well as for diagnosis of pathological intrarenal or perirenal disorders. Thermography is especially recommended for patients if postoperative haemodialysis is necessary. In these cases information can easily be achieved whether postoperative oligo-anuria is caused by acute tubular necrosis or by primary vascular insufficiency of the transplant.

[Quality criteria in Mammography (author's transl)].

Definite quality criteria must be observed to achieve optimum diagnostic success in mammography. These criteria refer to the apparatus, film, development of film, method and interpretation of findings. Cooperation with a mamma centre is discussed in case extended diagnosis of breast findings is required, or in case it becomes necessary to mark any non-palpable changes.

Endocrinology of pregnancy. I. Denominations of concentrations of triiodothyronine, thyroxine, effective thyroxine, thyreotrophin and growth hormone in normal pregnancy, labour and in cord blood.

Concentrations and activities of the following agents were estimated: triiodothyronine (T3), thyroxine (T4), effective thyroxine (ETR), thyreotrophin (TSH), and growth hormone (HGH). Blood samples were collected in pregnancy, labour and from the umbilical cord of the newborns. It was demonstrated that in normal pregnancy the concentrations of T3, ETR, and TSH did not differ significantly from the values considered as normal in non-pregnant women. The concentration of T4 was distinctly higher in the course of pregnancy (139 to 157 nmol/l versus 110 nmol/l in non-pregnant subjects). The HGH concentration increased during pregnancy from 5.6 to 14.3 micrograms/l. The cord blood demonstrated comparable values of ETR and HGH and in half of the cases of TSH also with those observed in the mothers. In the other one half of the cases, TSH activity was fourtimes higher than the material value. The T3 and T4 were lower than values in the mothers. The results presented are the normal values for further planned investigations of endocrinology of pregnancy, especially for studies into course of pregnancy in women who work in noxious conditions.

[Clinical evaluation of the antioestrogenic agent tamoxifen in the treatment of metastatic breast cancer (author's transl)].

The endocrine management of advanced breast cancer is of great clinical importance. Apart from the known therapeutic approach with oestrogens, androgens, gestagens and steroids, the oestrogen antagonist, tamoxifen appears to be a promising therapeutic agent. In this study from October 1st, 1975, to October 1st, 1976, the value of tamoxifen was examined in a controlled clinical trial. An objective remission after 3 months' treatment was achieved in 41% of the cases. The criteria of Karnofsky were used to evaluate clinical success. The median time of remission was 5,5 months. The determination of oestrogen receptors could provide a better selection of patients and, hence, help to achieve an increase in the remission rate. An interesting observation was a probably immunostimulative effect, but further investigations are necessary. The side-effects of treatment are detailed and the indications for the use of tamoxifen are discussed. More astonishing than the objective remission was the subjective improvement with relief of pain due to generalized bone metastases. On the basis of our observations it is concluded, that the use of the oestrogen antagonist, tamoxifen presents a potent alternative in the treatment of advanced and incurable breast cancer, especially in postmenopausal patients.

[Remarks on the paper: present means of lokalising intra-ocular foreign bodies, by M. Severin (author's transl)].

It is pointed out that the technique of Holzknecht can and should be considered one of the most important routine-measures for measuring radiologically visible foreign bodies in the eyes. This technique is as good as that of Comberg and has the great advantage that it only needs a ruler and compass, no other aids. It can be carried out by all radiologists. The technique of exposure and of measurement are discussed.

[Suction-radiography in mammography (author's transl)].

The value of the suction apparatus used in over 500 examinations as a simple addition to mammography has been convincing in our hands. Suction of 30 mm Hg, produced with a test-rubber bulb, achieves distension or stretching of the mamma. This leads to changes of position, shape and density of normal and pathologic structures and gives further information, compared with routine mammography. It is often possible to distinguish between spaces filled with fluid (cysts, hematomata) and solid tumours, pseudotumours and genuine growths, and between benign and malignant tumours. One essential indication is the "small" breast of various types (constitutional, post-operative and in men), because often suction will enable us to do a mammography. Suction radiographs are added in every 10th patient to previously taken compression radiographs with, of course, large and coned radiographs, which will yield a safe diagnosis in one half of the cases or confirm suspected findings.

[The radiological and scintigraphic findings in psoriatic arthropathy (author's transl)].

The radiological and scintigraphic findings in the skeletons of patients with psoriasis and psoriatic arthropathy are described. The results indicate that is it possible to detect inflammatory disease in joints by scintigraphy in patients who have not yet developed symptoms. The effect of treatment can be satisfactorily followed by serial scans. Further investigations and observations will be required to show whether the paravertebral calcification and syndesmophyte formation which has been described is really pathognomonic for psoriatic arthropathy.
