This survey-study represents the psycho-social conditions of death in West-German hospitals as seen from different occupational groups. The test, developed for this task, has been applied in 70 hospitals of different federal states, medical-departments and supporters. It is shown that following factors have an essential influence on the attitudes of people to the needs of the dying patient: amount of medical engineering at ward, time of professional activity and status of the personnel. In sum, the study gives a dark picture of death situation. Most helpers hold that situation inhumane. This is a burden for the helpers themselves. The results of the study tell against the efficiency of actual engagement in dying patients. The author develops some proposals, how the requests of thanatology that were adequat to improve the actual situation, could better be transferred to the practice.
Case report on a diabetic patient aged 68 years, who was operated on a cervical carcinoma by the method of Wertheim-Meigs. 3 weeks later a panaritium of the right little finger developed. X-ray examination resulted an osteoclastic process. The histology of the amputated end limb of this finger demonstrated a metastasis of a squamous cell carcinoma. The patient died 49 days after operation. Autopsy found a massive development of tumor with multiple far metastases.

Plasma testosterone was determined by radioimmunoassay in 36 prepubertal boys with hypospadia prior to and 3 days after stimulation with 5000 IU of human chorionic gonadotrophin (hCG). As a control group, 30 boys of comparable age, predominantly with unilateral cryptorchidism, were studied. The increase in plasma testosterone levels after hCG was (median and range) 204 (83-393) ng/100 ml in the control group, whereas in the hypospadiac group a median increase of only 90 (33-272) ng/100 ml was found. The difference between the median testosterone levels after hCG stimulation in the two groups investigated is statistically highly significant (P less than 0.0001). After hCG stimulation, 13 out of the 36 boys with hypospadia did not reach the lowest stimulated testosterone level (87 ng/100 ml) found in the control group. It is concluded that a substantial portion of the aetiologically obscure cases of hypospadia are caused by an endocrine testicular insufficiency.
After incubation of [4-14C]oestrone (E1) with liver slices from minipigs, the ether-soluble fraction contained [4-14C]oestradiol-17 beta (E2). In the protein-bound fractions, only polar metabolites were found, whereas in the water-soluble fraction the 3-monoglucuronide of oestriol (E1) was the preferred conjugate. When E2 was used as a substrate, E1 was present as main metabolite in the ether-soluble fraction. The radioactive metabolites in the protein-bound and water-soluble fractions were similar to those in the experiments with E1. The metabolism of E1 and E2 was dependent on age. Thus, the rate of conversion of oestrogens was greater in liver tissue of infertile male animals than in fertile males. In contrast, the two steroids were metabolised more rapidly in liver of fertile female minipigs than in infertile female animals. In fertile animals, the metabolic pattern of oestrogens in the ether-soluble, the protein-bound and the water-soluble fractions showed sex dependence: In females, E1 and E2 were metabolised to a greater extent by liver slices than in males. On the other hand, in experiments with male minipigs, E3-3-monoglucuronide was the only metabolite in the water-soluble fraction, whereas liver slices of female animals not only form E3-3-monoglucuronide, but also the 3-glucuronides of E1 and E2. The results described here show that, in liver tissue of minipigs, the oxidoreduction of E2 and E1 is the predominant reaction; in contrast to human liver, hydroxylation reactions play only a minor role. It may be concluded that there are differences in the metabolism of steroid hormones in man and minipig.
