[The Viennese physician Ludwig Teleky (1872-1957) and his "History of factory and mine hygiene" (author's transl)].

This article has the intention to show the merits of the Viennese physician Ludwig Teleky (1872-1957). A short introduction characterizes Teleky in the words of Prof. Dr. med. Heinrich Zangger (Zürich), the founder of the "Archiv für Gewerbepathologie und Gewerbehygiene", as one of the most distinguished representatives of modern industrial medicine. His life-work comprises more than 350 treatises, monographs and papers of his pupils. It was realized--in collaboration with his wife--in practical and theoretical research--at three places: Vienna, Düsseldorf and New York. After the period of Vienna, where Teleky's interest was wide-spread to the whole field of social medicine, it focused (since about 1925) upon the problems of industrial medicine (factories, mining and trade). Finally the author analyzes shortly Teleky's latest book entitled "History of Factory and Mine Hygiene", which was written in New York (published 1950). It is mostly a historical review of the state of industrial reality in Germany, Great Britain and in the U.S.A., seen by a most experienced physician of public and industrial health. It also deals with the development in other countries (France, Italy etc.).

[Treatment of motor dysfunction of the urinary bladder].

Symptoms and objective characteristics of 86 female patients with bladder instability and uninhibited detrusor contractions suffering from urgency incontinence were analyzed. The subjective and objective response to a six week-parasympathicolytic treatment with Emepronium-Bromide (Cetiprin) was examined and the results are discussed.

[Management of second stage of labour: observations, reflections, advices (author's transl)].

All vaginal deliveries of the Department of Obstetrics and Gynecology of the University Basel (N = 4081) during the year 74/73 and of the University Tübingen (N = 3249) 75/74 were analysed using an IBM-system 370/135 Only alive singletons beyond the 28th week of gestation were analysed. Clinical management was quite different in the two departments; the incidence of vaginal operations (Basal 11.2%, Tübingen 12.6%), however, as well as the distribution of pH-values and Apgar-scores after 1 min were quite similar. Basel: Acidotic risk (i.e. pHUA less than 7.200) 13.5%, severe acidotic risk (i.e. pHUA less than 7.100) 1.55%, low Apgar-scores (1--3) 0.7%. Tübingen: :12.3%, 2.11%, 1.6%. 3.5% of all parturients (Basel) had duration of second stage of labour with active maternal pressure support lasting more than 30 min. In two highly selected samples differing only with regard to the occurrence of cord-entanglements at birth (N1 = 1755, N2 = 1098) the association (rank correlation method according to Kendall) between the parameters of the fetal acid-base balance and the duration of second stage of labour as well as duration of the period with "active bearing down" was studied. Without cord encirclements pH in the umbilical artery fall --0.087 and in the umbilical vein --0.115 units and with cord complications the values amounted to --0.062 (UA) and --0.120 (UV) respectively pro 60 min duration of second stage with "bearing down efforts". Analogous computations for pCO2, pO2 and HbO2 are presented. Apgar-scores in these samples showed a very loose connection with the time variables. From these data the conclusion is drawn that the indication to perform vaginal operations for termination of delivery should not primarily be governed by the factor time but rather by the whole obstetrical situation i.e. the possible fetal risk of the intervention. This holds only if maternal welfare is established and fetal well being is monitored continuously.

[Elementary diet as an alternative to parenteral feeding in severe gastrointestinal diseases].

21 patients with gastroenterological disease and indication for the use of intravenous nutrition received an elemental diet (ED) for 5-44 days. In 6 out of 8 patients with exacerbation of Crohn's disease remissions were achieved, apart from 3 persistent fistulas. In 5 out of 9 cases with various primary diseases and postoperative intestinal fistulas, spontaneous healing was observed. Furthermore, 2 patients with ulcerative colitis, 1 with radiation enteritis and 1 with pancreatitis were treated with ED. On ED, hemoglobin increased from 11.3 +/- 0.4 (m +/- SEM) to 12.0 +/- 0.5 g% (p less than 0.01) and serum albumin from 2.7 +/- 0.1 to 3.4 +/- 0.1 g% (p less than 0.001). Nitrogen requirements were studied in 11 patients receiving various quantities of ED. Nitrogen balance was found to be in equilibrium or positive in 7 patients, and negative in 4. In one patient with severe ulcerative colitis, fecal nitrogen losses were higher than urinary nitrogen losses. The unpleasant taste of ED resulting from free amino acids limited the ED supply in 3 patients and led to premature ending of ED administration in 3 other patients. In such cases ED may be given by nasogastric tube feeding. From the results presented it appears that ED is indicated in Crohn's disease and intestinal fistulas. However, the results obtained require confirmation by further observations and comparison with an intravenously fed control group.

Response of fetal acid--base balance to duration of second stage of labour.

Data from 4081 vaginal deliveries (no caesarean sections) were analyzed retrospectively (IBM 730/158) with regard to duration of second and "final stage" of labour and fetal outcome (acid-base balance and apgar scores). The average duration of the two periods amounted to 22.8+/-29.6 and 9.9+/-7.8 min. Mean pH (UA) was 7.268+/-0.084 and the acidotic risk (pH less than 7.20, pH less than 7.10) 13.4 and 1.6% respectively. The distribution of the Apgar-scores after 1 min was assessed: 0-3: 1.7%, 4-6: 5.4%, 7-10: 92.9%. The dependance of the time variables from parity was studied. Two samples (N1=1755, N2=1098) of uncomplicated term pregnancies were chosen according to 7 clinical selection criteria differing only in the presence of cord entanglements at birth. The association between the two time variables and parameters of the fetal acid-base balance in cord blood was evaluated using rank correlation- and polynomial regression analysis. Highly significant correlations (tau) were found between the variable time and actual pH in blood of the umbilical artery and vein as well as pCO2, BEECF and HbO2 in the umbilical vein. The association however is not very close and thus clinically not of great importance. The deltapH (UA & UV) pro 60 min of second (and "final") stage of labour was computed and amounted to -0.024 (-0.087) in blood of the umbilical artery and -0.036 (-0.115) in blood of the umbilical vein and -0.017 (-0.062) (UA) and -0.032 (-0.120) units (UV) in the sample with and without apparent cord entanglements at birth respectively. The response of fetal acid-base balance to cord compression during second stage of labour was assesses: The acidotic risk (pH less 7.2) was doubled: 14.5% (7.7%) and AV-differences of all variables were "opened" if cordcoilings were observed. Apgar scores were not significantly different. Moreover, the association between AV-differences of each parameter and the variable time was studied: it became evident that with passage of time AV-difference is "closed" (-0.052 AV DpH/60 min "final stage" of labour, N=1098) indicating time related impairment of placental function. From these observations and data of the literature the conclusion is drawn that second stage of labour should not exceed 45 min in any patient. Furthermore it is concluded that in cases without signs of impending fetal distress it seems to be possible to wait more than 20 (Multipara) or 30 min (Primipara) duration of "final stage" without increased risk of fetal peril measured in terms of acidemia and clinical depression. This is valid only in term pregnancies with the possibility of continuous monitoring of FHR, in cases with normal uterine activity, uneventful course of first stage of labour and cooperative, vigorous patients. The indications for termination of delivery by vaginal operations in cases without impending fetal distress are discussed.
