    Notes: Summary Teeth from people aged 5–73 years old, who differ in their occupational type of exposure to lead and who live in different areas of Dortmund, were collected in 1980/81 and were investigated by means of flameless atomic absorption spectrometry. The major result obtained from the 163 permanent and 22 deciduous teeth studied was a statistically significant dependence of the lead content of the permanent teeth on the donor's age. This was superior to all other influences, showing an increase of 3.4% per year of life. There were no sex specific differences, and no correlations with height and body weight were found. To find different lead concentrations within samples of teeth of various living areas and various occupational types of exposure would have required more variation in these variables than was available in the population of our study. It must be emphasized that the reliability of the measured values of dental-lead concentration greatly depends upon the methodical and analytical procedures used, especially because of the overall lead contamination. The analytical method we finally used is described. The factors which influence the dental lead concentration are discussed. The investigation of whole teeth is tolerable. The age-dependent values of the lead content of teeth could be a useful indicator of the overall lead uptake especially in continuous low level lead exposure. Under the conditions described, at least 150 permanent teeth are needed to compare samples of different regions or periods.

    Description / Table of Contents: Zusammenfassung Die BKS und 12 Plasmaproteine von 21 Kranken mit unterschiedlichen Krankheiten wurden statistisch miteinander verglichen. Dabei ergaben sich positive Korrelationen zwischen der BKS und dem sauren α1-Glykoprotein und der BKS und dem α1-Antitrypsin, eine negative Korrelation zwischen der BKS und dem Transferrin. Außerdem korrelierten das saure α1-Glykoprotein und das α1-Antitrypsin sowie das saure α1-Glykoprotein und das Transferrin miteinander. Bei der Deutung dieser Ergebnisse müssen einerseits Gemeinsamkeitskorrelationen in Betracht gezogen werden, zum anderen die Möglichkeit, daß zwischen bestimmten Proteinmustern und der BKS Zusammenhänge bestehen.
    Notes: Summary In 21 male patients with different diseases the ESR as well as 12 plasma proteins were determined by the Westergren method and the radial immunodiffusion technique by Mancini, respectively. Significant positive correlations were found between the ESR on one side and the plasma content of α1-acid-glycoprotein (〈0.001) and α1-antitrypsin (p〈0.01) on the other, whereas a significant negative correlation (p〈0.01) was observed between ESR and plasma transferrin content. There were also statistically significant connections between α1-acid-glycoprotein and α1-antitrypsin as well as between α1-acid-glycoprotein and Transferrin. However, no such correlation existed between α1-antitrypsin and transferrin. The implications of these findings with regard to some disease patterns with high ESR are discussed.

    Notes: Summary In 101 unselected autopsies, cadmium (Cd) in lung tissue was analyzed by means of flameless atomic absorption spectrometry (AAS). The subjects originated from Bochum (BO), Dortmund (DO), and neighbouring cities in the Ruhr District (BO/DO) as well as from Muenster (MS) and vicinity. The sample included eight persons who had died from bronchial carcinoma. The Cd concentration in lung tissue (CdL) did not show a significant age-dependency. There was only a slight increase of CdL in the age around 50. For males, the median CdL value was found to be 1.32 μg/g dry wt in the age group from 20–45, 1.48 μg/g dry wt from 45–65, and 0.64 μg/g dry wt 〉 65 (the corresponding means and standard deviations were 1.48 ± 1.22, 1.73 ± 1.42, and 1.18 ± 1.27 μg/g dry wt). CdL in men was twice that in women. There were no differences between the two regions (BO/DO : MS) examined. CdL of the bronchial carcinoma cases were mostly clearly above the expected level, often similar to the Cr and Ni concentration of the same specimens. Besides the amount of inhaled metal aerosols, insufficient lung clearance may play a leading role for their retention in lung parenchyma. However, with regard to the determination of causality between uptake and disease the data are difficult to interpret, in our study due to a lack of enough consistent and reliable data on occupation, environment, and smoking habits, and in general due to a lot of variables which, until now, cannot be sufficiently quantified.

    Notes: Summary In random autopsies chromium (n=23) and nickel (n=16) together with various other metals, were determined in lung tissue by means of flameless atomic absorption spectrometry. With increasing age a significant increase in concentration of both chromium and nickel was found. This is evaluated as an indicator for a corresponding exposure, which is marked by a local (workplace) and regional (environment) share of a clear increase in the total chromium/nickel load and by a life-long duration. The question arises, whether the selective concentration (long half-life) of the inhaled chromium and nickel particles/compounds in the lung are to be regarded as a stochastic lung cancer risk.

    Description / Table of Contents: Summary While tuberculosis tends to increase its chronic course evaluation of data found and assessment of therapy applied become difficult. To our experience the outpatient-department by these increasing difficulties seems to be especially concerned. A way out of the impairment was found by setting up a special card. This card allows documentation of data in a manner that seemingly meets the requirements of recent medical knowledge. The card may be handled without greater loss of time. Since the form turned out to be useful in this hospital detailed explanation is given for the use of others.
    Notes: Zusammenfassung Mit zunehmender Chronizität werden Krankheitsverläufe von Tuberkulosen unübersichtlicher. Von dieser Unübersichtlichkeit ist vor allem die Tuberkulose-Ambulanz betroffen. Deswegen wurde eine dokumentationsgerechte, arbeitsökonomische, praktischen und wissenschaftlichen Erfordernissen angepaßte Karte zur ambulanten Überwachung Tuberkulosekranker entwickelt. Diese Karte hat sich inzwischen als brauchbar erwiesen; sie wird hier mit den entsprechenden Erklärungen wiedergegeben.

    Description / Table of Contents: Zusammenfassung Capreomycin wurde in Kombination mit anderen Tuberkulostatica bei 24 Silikotuberkulose-Kranken angewandt. Wird die besondere Situation der schweren Siliko-Tuberkulose berücksichtigt, so haben wir bei Wertung aller Befunde, die unter und nach der Behandlung erhoben wurden, den Eindruck, daß Capreomycin ein brauchbares tuberkulostatisches Antibioticum ist. Capreomycin wurde gut vertragen. Nebenerscheinungen traten nur selten auf, sie waren nicht schwerwiegend und bildeten sich nach Absetzen des Capreomycins umgehend wieder zurück. Unter Capreomycin wurde keine wesentliche Verschlechterung des Audiogramms festgestellt. Desgleichen ergaben sich keine Anhaltspunkte für Lebertoxicität. Lediglich einmal wurde eine nephrotoxische Reaktion — bei vorgeschädigten Nieren — beobachtet. Vereinzelt entwickelte sich allergisches Exanthem, wobei Sensibilisierung gegenüber Capreomycin nachgewiesen wurde. Es bleibt vorerst offen, inwieweit mit primären Resistenzen der Keime gegenüber Capreomycin zu rechnen ist.
    Notes: Summary Capreomycin was given in combination with other tuberculostatics to 24 patients suffering from silico-tuberculosis. Considering the special situation of severe silicotuberculosis it is our opnion, appraising all findings during and after treatment, that C. is a useful tuberculostatic antibiotic. C. was tolerated well. Side effects occured rarely. They were not serious and disappeared after C. was discontinued. There was no deterioration of the audiogram while C. was applied. No evidence of liver toxicity was found. Merely in one case, a nephrotoxic reaction — this patient had a kidney disease — was observed. An allergic exanthema developed in a few cases in which sensitivity to C. could be proven. It remains to be seen in how many cases primary resistances might exist.

    Description / Table of Contents: Summary Comparable data for patients suffering from chronic progressive tuberculosis that can be used as points of reference, for example in examining the effect of chemotherapy, are difficult to obtain and often incorrect. Dates of death however are unequivocal. Therefore, the age of miners who died of silico-tuberculosis in Germany was closely examined. We compared the age of death of silico-tuberculosis patients with the age of death of silicosis patients. From 1954 through 1964, 5310 miners died of the sequelae of silico-tuberculosis, 15695 of the sequelae of silicosis. Prior to this time, the yearly death rate was probably higher. Both groups are, as we have illustrated, homogeneous. The average age of death of patients with silico-tuberculosis was 13,6 years higher in 1964 than it was during the period of time of 1937 through 1940, and 9,6 years higher than in 1948. The average age of death of patients with silicosis did rise in about the same manner. The life expectancy of the silicosis and silico-tuberculosis miners approached the life expectancy of the general population steadily. The mortality of silico-tuberculosis patients decreased, probably due to a less frequent occurrence of tuberculosis in connection with silicosis. For the average age of death, a regression analysis was performed for both groups for the period of time from 1948 through 1964. These equations were extrapolated to 1970. This made a further rising trend obvious which will most likely level off in 1970. The calculated (max.) age of death for patients suffering from silico-tuberculosis will then be 66,0 years, and of patients suffering from silicosis 67,5 years. The cause for this rise is discussed. In addition the change of the mean age of death was established and an explanation was given why several points exceeded the standard deviations. Through the regression analysis and the determination of the change of the average age of death, points of reference were established that may be useful in examining the success of the present as well as of a future modified chemotherapy.
    Notes: Zusammenfassung Bei chronisch progressiven Tuberkulosen sind vergleichbare Krankheitsdaten, die als Bezugspunkte beispielsweise bei der Untersuchung der chemotherapeutischen Effektivität dienen könnten, schwierig zu gewinnen und meistens mit einer großen Fehlerbreite behaftet. Demgegenüber sind die Sterbedaten eindeutig. Deswegen wurde das durchschnittliche Sterbealter der in der Bundesrepublik Deutschland an den Folgen einer Siliko-Tuberkulose verstorbenen Bergleute untersucht. Die an den Folgen einer Silikose Verstorbenen wurden als Vergleichskollektiv gegenübergestellt. 1954 bis 1964 starben 5310 Bergleute an den Folgen einer Siliko-Tuberkulose, 15695 an den Folgen einer Silikose. Vordem waren die jährlichen Todesfälle wahrscheinlich zahlreicher. Die beiden Kollektive sind aus näher erläuterten Gründen vergleichsweise homogen. Das durchschnittliche Sterbealter bei Siliko-Tuberkulose lag 1964 13,6 Jahre höher als in der Zeit von 1937 bis 1940, 9,6 Jahre höher als 1948. Ziemlich parallellaufend stieg auch das durchschnittliche Sterbealter bei Silikose an. Der Abstand zu dem durchschnittlichen Sterbealter der übrigen Bevölkerung wurde stetig kleiner. Außerdem sank die Siliko-Tuberkulose-Mortalität, wahrscheinlich infolge der abnehmenden Tuberkuloserate bei Silikose. Für das durchschnittliche Sterbealter wurden getrennt für beide Kollektive für die Jahre 1948 bis 1964 Regressionsanalysen durchgeführt und die Gleichungen über ihren Gültigkeitsbereich hinaus bis 1970 extrapoliert. Dadurch ließ sich eine Entwicklung bestimmen mit einem durch Extrapolation ermittelten Anstieg bis etwa 1970. Das errechnete (max.) durchschnittliche Sterbealter der Siliko-Tuberkulose-Kranken beträgt dann 66,0 Jahre, das der Silikose-Kranken 67,5 Jahre. Die Ursachen des Anstieges wurden diskutiert. Außerdem wurde die zeitliche Änderung des durchschnittlichen Sterbealters ermittelt, die mehrere aus dem einfachen Streubereich herausfallende Werte ergab. Für diese Werte boten sich naheliegende Erklärungen an. Durch die Regressionsanalysen und die Bestimmung der zeitlichen Änderung des durchschnittlichen Sterbealters wurden Bezugspunkte gewonnen, die sich bei der Untersuchung von Detail-Entwicklungen als brauchbar erweisen könnten, so bei der Analyse der zur Zeit geübten, aber auch einer gegebenefalls geänderten Chemotherapie.
