    Notes: Heartburn is a normal consequence of pregnancy. The predominant aetiology is a decrease in lower oesophageal sphincter pressure caused by female sex hormones, especially progesterone. Serious reflux complications during pregnancy are rare; hence upper endoscopy and other diagnostic tests are infrequently needed. Gastro-oesophageal reflux disease during pregnancy should be managed with a step-up algorithm beginning with lifestyle modifications and dietary changes. Antacids or sucralfate are considered the first-line drug therapy. If symptoms persist, any of the histamine2-receptor antagonists can be used. Proton pump inhibitors are reserved for women with intractable symptoms or complicated reflux disease. All but omeprazole are FDA category B drugs during pregnancy. Most drugs are excreted in breast milk. Of systemic agents, only the histamine2-receptor antagonists, with the exception of nizatidine, are safe to use during lactation.

    Notes: Although recent studies suggest that gastro-oesophageal reflux disease may frequently contribute to ear, nose and throat and respiratory diseases, the cause-and-effect relationship is far from proven. The review will address this controversial topic emphasizing recent literature raising concerns about the credibility of this association and our tests to make this diagnosis. The author believes these extraoesophageal symptoms suspected to be secondary to gastro-oesophageal reflux disease are an unresolved issue, but selective use of aggressive proton-pump inhibitor therapeutic trials may help to resolve this problem in our individual patients.

    Description / Table of Contents: Summary From the agreement of morphologic, physical, and biochemical studies it could be shown that the course of healing of an experimental laparotomy wound in the rat was better if species-specific soluble collagen were administered. The negative results reported by other authors in similar studies may be related to the heterologous nature of the collagen used.
    Notes: Zusammenfassung Nach Verabfolgung von arteigenem löslichem Kollagen konnte an experimentellen Laparotomiewunden der Ratte ein besserer Wundheilverlauf festgestellt werden in Übereinstimmung mit morphologischen, physikalischen und biochemischen Untersuchungen. Die von anderen Autoren mitgeteilten negativen Ergebnisse bei ähnlichen Versuchen werden auf die artfremde Herkunft des Kollagens zurückgeführt.

    Description / Table of Contents: Summary The myocardial extraction of acetoacetate and β-hydroxybutyrate was determined in 55 metabolically normal patients during diagnostic heart catheterizations. In order to obtain a complete insight into the substrate supply of the myocardium, arterio-coronary-venous differences of glucose, lactate, pyruvate, non esterified fatty acids, amino acids and oxygen were also measured. From the considerably varying arterial concentrations of acetoacetate (7,2±0,66 µMol/100) and β-hydroxybutyrate (21,3±2,6 µMol/100) the human heart muscle extracts an average of 50% acetoacetate (3,6±0,36 µMol/100) and 35,2% β-hydroxybutyrate (7,5±1,2 µMol/100). Both substrates showed a statistically significant correlation between arterial concentration and myocardial extraction. The β-hydroxybutyrate/acetoacetate quotient was found to be 2,87±0,25 in the arterial and 3,69±0,31 in the coronaryvenous blood. Although a high percentage of the arterial level of acetoacetate is extracted by the heart, this substrate accounts for only 2,6±0,3% of the total oxydative myocardial metabolism. The value for β-hydroxybutyrate at 6,0±1,0% is considerably higher, thus obtaining an oxygen extraction ratio of 8,6% for the total ketone-bodies. The other substrates involved in the myocardial metabolism showed oxygen extraction ratios similar to those previously reported by our group: glucose 14,5±1,9%, lactate 12,9±1,1%, pyruvate 1,0±0,1%, non esterified fatty acids 69,7±3,0%. With higher arterial levels of ketone-bodies an increase of their oxygen extraction ratio was found, whereas the uptake of carbohydrates was proportionally decreased. The percentual extraction of non esterified fatty acids did not change. These results indicate that the myocardium oxidizes ketonebodies in preference to carbohydrates. The redox-potentials of the β-hydroxybutyrate/acetoacetate and the lactate/pyruvate systems are changed across the heart in an opposite way. The β-hydroxybutyrate/acetoacetate system becomes more negative (ΔE=−3,1±0,6 mV), the lactate/pyruvate system tends to be slightly positive (ΔE=+0,9±0,63 mV).
    Notes: Zusammenfassung Das Verhalten von Acetacetat und β-Hydroxybutyrat im Stoffwechsel des menschlichen Herzens wurde im Rahmen diagnostischer Herzkatheterisationen an 55 stoffwechselgesunden Patienten untersucht. Außerdem erfolgte die Bestimmung der arterio-coronarvenösen Differenzen für Glucose, Lactat, Pyruvat, nicht veresterten Fettsäuren, Aminosäuren und Sauerstoff, um einen vollständigen Einblick in die Substratversorgung des Myokards zu erhalten. Bei physiologisch stark schwankenden arteriellen Konzentrationen von Acetacetat (7,2±0,66 µMol/100) und β-Hydroxybutyrat (21,3±2,6 µMol/100) extrahiert der Herzmuskel vom Angebot durchschnittlich 50% Acetacetat (3,6±0,36 µMol/100) und 35,2% β-Hydroxybutyrat (7,5±1,2 µMol/100). Für beide Substrate konnte zwischen arterieller Konzentration und myokardialer Extraktion eine statistisch gesicherte Abhängigkeit nachgewiesen werden. Der Quotient β-Hydroxybutyrat/Acetacetat beträgt arteriell 2,87±0,25 und coronarvenös 3,69±0,31. Der Anteil von Acetacetat am oxydativen Stoff-wechsel des menschlichen Herzens erreicht trotz hoher prozentualer Extraktion nur 2,6±0,3%. Der Wert für β-Hydroxybutyrat liegt mit 6,0±1,0% wesentlich höher, so daß sich für die Gesamtketonkörper ein Sauerstoffextraktionsquotient von 8,6% ergibt. Für die übrigen am Myokardstoffwechsel beteiligten Substrate errechnen sich Sauerstoffextraktionsquotienten, die in den von uns bereits früher angegebenen Bereich fallen: Glucose 14,5±1,9%, Lactat 12,9±1,1%, Pyruvat 1,0±0,1%, nicht veresterte Fettsäuren 69,7±3,0%. Bei überdurchschnittlich hohen arteriellen Ketonkörperkonzentrationen nimmt der Anteil der Ketonkörper am gesamten oxydativen Stoffwechsel des Herzens beträchtlich zu, während die Kohlenhydrate in etwa gleicher Größenordnung abnehmen. Die nicht veresterten Fettsäuren zeigen keine Änderung ihrer prozentualen Extraktion. Die Ketonkörper stellen somit gegenüber den Kohlenhydraten ein vom Herzmuskel bevorzugtes Substrat dar. Die Redoxpotentiale der Substratpaare ß-Hydroxybutyrat/Acetacetat und Lactat/Pyruvat werden bei der Herzmuskelpassage im Prinzip in gegensätzlicher Weise verändert, und zwar erfährt das β-Hydroxybutyrat/Acetacetat-System eine Negativierung (ΔE=−3,1±0,6 mV) und das Lactat/Pyruvat-System eine angedeutete Positivierung (ΔE=+0,9±0,63 mV).

    Description / Table of Contents: Summary A case of ectopic ACTH syndrome is reported presenting with hypercorticism and pronounced hypokalemic alkalosis in a woman aged 55 y. with metastatic cancer of the pancreas. The failure to show a significant difference of plasma ACTH-levels from bulbus superior venae jugularis resp. femoral vein supported the clinical assumption of non pituitary origin of elevated plasma ACTH.
    Notes: Zusammenfassung Es wird über einen Fall von ektopischem ACTH-Syndrom mit Hypercortizismus und hypokaliämischer Alkalose bei einem metastasierten Pankreas-Carcinom berichtet. Das Fehlen einer Differenz zwischen den ACTH-Spiegeln im Plasma aus dem Bulbus cranialis venae jugularis und aus der Vena femoralis unterstützte die Annahme einer nicht hypophysären Herkunft der erhöhten ACTH-Spiegel.

    Description / Table of Contents: Summary A group of clinically euthyroid obese patients was found to have significantly lower PBI-values (4,47 γ-%) than controls (5,09 γ-%). Binding of triiodothyronine-125I to serum proteins as estimated by dextran gel filtration was significantly increased in the obese group (87,64 vs. 84,98%).
    Notes: Zusammenfassung Das proteingebundene Jod im Serum wurde bei einer Gruppe von adipösen Patienten im Mittel signifikant vermindert gegenüber dem Mittelwert eines Normalkollektivs gefunden. Die Bindung von Trijodthyronin-125Jod an Serumproteine war bei Adipositas signifikant erhöht.
