    Description / Table of Contents: Zusammenfassung Postmortale Gewebsionogramme der rechten und linken Herzkammer werden bei 93 Fällen mit Hilfe der Atomabsorptionsspektralphotometrie analysiert. Eine signifikante, lineare Abhängigkeit wird für den Wassergehalt und die Natrium-, Kaliumund Magnesiumkonzentrationen errechnet. Der Vergleich verschiedener kardialer und extra-kardialer Todesursachen erbringt keine Unterschiede im postmortalen Ionogramm beider Herzkammern. Eine Abhängigkeit zwischen Alter und Mineralgehalt der Herzmuskulatur wird bei diesem Kollektiv kranker Patienten für keines der untersuchten Mineralien nachgewiesen. Das postmortale Ionogramm des Herzmuskels erfährt durch die Summation zahlreicher Todesursachen unter dem Einfluß der modernen Intensivtherapie einen Gestaltwandel. Bei gleichzeitiger Beachtung aller Parameter des Ionogrammes, insbesondere des Wassergehaltes und der Kationenosmolalität, sind postmortal im Einzelfall Aussagen über lokale und/oder systemische Störungen des Wasser-Elektrolyt-Haushaltes möglich, die bei alleiniger morphologischer Untersuchung nicht erfaßt werden.
    Notes: Summary Mineral and water content of the right and left heart muscle were analyzed by atomic absorption spectrophotometry in 93 autopsy cases. Sodium, potassium, magnesium, and calcium concentrations were measured after acid digestion of tissues. Marked differences of the element distribution of both ventricles are seen constantly, although a significant correlation between water content and sodium as well as potassium and magnesium concentrations in both ventricles is seen. Comparing multiple causes of death (cardiac and noncardiac) there are no differences in the postmortem mineral contents of heart muscle. Age-dependent correlations of mineral concentrations (as seen by Burger, 1960) were not detectable in this investigation. Postmortem mineral analyses of human heart muscles are excessively influenced by modern intensive care. Most of our cases had several causes of death, one of which was to be declared as the main cause of death in the necropsy record. Postmortem chemical mineral analysis of heart muscle can give an exact description of local variations and—in special cases—signs of general disorders of mineral metabolism, which are not detected by exclusively histologic investigations.

    Notes: Summary 116 patients from 4 clinics participated in a double blind study to assess the efficacy of (BAYl 5240), a nifedipine-acebutolol fixed combination (10 mg+100 mg), as compared to nifedipine 20 mg in essential hypertension. During the 10 week study, the mean recumbent blood pressure decreased 1 to 3 h after treatment from 175.5/105.2 to 148.3/88.0 mmHg in the BAY1 5240 group and from 174.3/102.9 to 150.3/86.5 mmHg in the nifedipine group. The results also showed a comparable decrease in the mean systolic (SBP) and diastolic (DBP) blood pressures before treatment (24 h after last tablet) and after physical exertion before and after either drug given for 4 weeks. Doubling of the dose for 4 additional weeks produced a moderate and similar additional decrease in blood pressure. The results show the possibility of treating essential hypertension with a low dose of a beta-adrenergic blocking agent in combination with 10 mg nifedipine. Both regimens were well tolerated. One patient in the BAYl 5240 group and 2 in the nifedipine group, all treated by the same investigator, were withdrawn from the study because of headache during the nifedipine pre-period.

    Notes: Summary The remission rates after endocrine and cytostatic treatment were determined in 192 female patients with advanced breast cancer depending on the estrogen, progesterone, and androgen receptor content and on the diseasedominant site. Of 60 women with tumors containing estradiol receptors 39 responded to endocrine treatment. This was only true in two of 31 women without estradiol receptors. Tumors which contained binding sites for both estradiol and progesterone had a higher remission rate after endocrine therapy than those with estradiol receptors only. Remission rates after polychemotherapy were also higher in tumors with binding sites for estradiol as well as for progesterone. The localisation of metastases seems to be of lesser importance for the remission rate than the receptor content. Liver metastases are an exception. Here, no remissions could be observed with endocrine treatment even if ER and PR were present. The median remission rate was 9 months for hormonally treated patients and 10 months for those undergoing chemotherapy. The median survival time after chemotherapy is 18 months higher for responders than for non-responders. This difference is 15 months with endocrine treatment. Two years after the start of endocrine treatment 60% of the responders but only 20% of the non-responders were still alive. Based on our results together with histomorphological studies and the evaluation of recurrence and survival it can be assumed that carcinomas, which by nature follow a more benign course, do contain estradiol receptors.

    Notes: Summary The incidence of two simultaneous carcinomas within the organism is 5%, in the region of the upper airways and alimentary tract, less than 1%. With the aid of systematized clinical endoscopic and cyto-histomorphological screening procedures for carcinomas along the “smoker's pathway“, concomitant carcinomas and pre-cancerous states are being detected more and more frequently and at an earlier stage. Between 1976 and 1978, 210 patients presenting with oral leukoplakia of varying genesis and localization, and both benign and malignant, were subjected to systematic dermatological, dental and ENT examinations. A therapy-relevant finding in the ENT region was found in every third patient. In 41 patients with oral pre-cancerous conditions and carcinomas, similar concomitant findings were seen in the larynx in 15%, localized in the glottis in 90% of the cases. — Etiologically particularly high-risk patients proved to be men over 30, with oral leukoplakia and poor oral hygiene and a history of regular smoking and consumption of considerable quantities of alcohol. The basis for the detection of concomitent or consecutive pre-cancerous conditions and early cancers in the region of the upper airways and alimentary tract is the interdisciplinary cooperation covering the inspection of the oral cavityand pharynx and larynx.

    Description / Table of Contents: Zusammenfassung Aufgrund der vollständig und sorgfältig dokumentierten Verlaufsdaten von 237 kurativ operierten Patienten mit Carcinomen des mittleren Rectumdrittels wurde ein multivariates statistisches Modell entwickelt und dessen Parameter bestimmt. Damit kann das individuelle Risiko von Lokalrezidiven nach Rectumresektion mit engem Sicherheitsabstand (11–30 mm am frischen Resektat ohne Zug gemessen), nach Rectumresektion mit weitem Sicherheitsabstand (mehr als 30 mm) und nach Rectumexstirpation geschätzt werden. Sieben prä- und intraoperativ bestimmbare prognostische Faktoren werden hierbei berücksichtigt. Die Schätzungen des Rezidivrisikos auf der Basis beobachteter und dokumentierter Verläufe sind als Entscheidungshilfen bei der Differentialindikation Resektion/Exstirpation bei künftigen Patienten verwertbar. Wenn eine Resektion vorgenommen wird, kann nach makroskopischer Beurteilung des Resektionspräparates unter Mitberücksichtigung der Schnellschnittergebnisse noch intraoperativ das Rezidivrisiko anhand des Modells berechnet werden. Ergeben sich bei Resektion und Exstirpation annähernd gleiche Rezidivrisiken, wird die Resektion durch Anastomosierung abgeschlossen, andernfalls die Operation zur Rectumexstirpation erweitert. Das vorgestellte Modell bietet die Möglichkeit, das Operationsverfahren der individuellen Situation anzupassen (histologie- und stadiengerechte Therapie).
    Notes: Summary On the basis of completely and exactly documented follow-up data of 237 patients on whom carcinomas of the middle rectum were resected for cure, a multivariate statistical model was developed and the corresponding parameters were calculated. With this model the individual risk of local recurrences can be estimated after anterior resection with a small margin of clearance (11–30 mm on the fresh specimen without stretching), after anterior resection with a wide margin of clearance (more than 30 mm), and after excision of the rectum. Seven prognostic factors are taken into consideration that can be determined pre- and intraoperatively. Estimations of the risk of local recurrences on the basis of observed and documented follow-up data can be used as decisive factor for differential indication between restorative and excisional surgery on future patients. After anterior resection the risk of local recurrences is calculated according to macroscopic findings on the specimen and to frozen section histology. If the risks in anterior resection and excision are approximately equal, the resection is ended by anastomosis; otherwise the operation will be extended to excision of the rectum. This statistical model enables the surgeon to select the proper operative procedure for each individual situation (histology-and stage-adapted surgery).
