    Notes: Summary To determine the short-term and long-term effects of organic solvents on the respiratory tract, 26 male floorlayers exposed to organic solvents were compared with 36 persons unexposed to such substances. The investigation primarily included a detailed history, determination of solvent concentration in the air inhaled by the workers, long-term ECG during the entire shift and lung-function test (vital capacity, forced expiratory volume in one second, flow volume curve) as well as non-specific bronchial inhalation challenge using a 3% acetylcholine aerosol before and after the shift. The floor-layers were primarily subjected to inhalative exposure to adhesives containing mixtures of toluene, petroleum hydrocarbons, ethyl acetate, methanol and acetone or one of these substances alone. This frequently resulted in short-term value limit excesses, especially in the MAK value (standardised threshold concentration in Germany) for toluene, which is a prime component of neoprene glue. Of the 26 floorlayers, 6 complained of breathlessness and coughing, whereas 13 suffered from nasal discharge and blockage — symptoms closely related to work. The smokers in this group showed a decline in lung function during the shift — especially in the forced expiratory volume in 1 s (FEV1) — as compared with the non-smokers in this group and the persons in the control group. This is probably due to the combination of noxious substances. A strong correlation between occupational age and changes in lung function was observed: the occupationally youngest workers demonstrated the highest decrease in values during the course of the shift. There was no evidence of either obstructive or restrictive respiratory disorders or of marked deviation from the European Community for Coal and Steel (ECCS) references. Our findings give rise to the hypothesis that due to a healthy-worker effect, cross-sectional studies fail to detect long-term impairment of the respiratory tract in persons exposed to solvents.

    Notes: Abstract  A-52-year-old patient presented with a 2-year history of multiple myeloma, recurrent episodes of hypercalcemia, and extensive bone involvement. She developed pulmonary infiltrates, initially misdiagnosed as interstitial pneumonia. High-resolution computed tomography and bone scintiscanning indicated pulmonary calcification, which was confirmed by a transbronchial biopsy. Cytostatic treatment of multiple myeloma in combination with repetitive i.v. administration of bisphosphonates over a period of 6 months led to a significant improvement of clinical symptoms. Regression of pulmonary infiltrates was demonstrated by chest radiograph and computed tomography. There are only a few reports on pulmonary calcification in patients with multiple myeloma; the condition was associated mostly with progressive disease, kidney failure, adult respiratory distress syndrome and bad prognosis. In our patient isolated calcification of the lungs without involvement of other organ systems was successfully treated. These findings suggest that interstitial pulmonary calcinosis in multiple myeloma can be reversed by normalization of serum calcium levels using bisphosphonates combined with cytostatic treatment.

    Description / Table of Contents: Zusammenfassung Unter 60 Duodenopankreatektomien der letzten 5 Jahre wurden 23 totale Duodenopankreatektomien durchgeführt: 15 mal wegen komplizierter chronischer Pankreatitis und 8 mal wegen Carcinom. Die Operations- bzw. Hospitalletalität betrug 4 % (1 Patient verstarb 12 Tage post-operativ an einer Kathetersepsis). Es werden die Operationsindikation, die Operationstechnik Bowie postoperative Überwachung und Therapie Bowie die Ergebnisse demonstriert.
    Notes: Summary Among 60 duodenopancreatectomies performed during the past 5 years there were 23 total pancreatectomies, 15 of which were performed for chronic complicated pancreatitis and 8, for carcinoma. The operative and hospital mortality was 4 % (1 patient died on the 12th postoperative day of a venous catheter sepsis). Indications for operation, technique, postoperative care, and long-term therapy are demonstrated.

    Description / Table of Contents: Zusammenfassung An weiblichen Sprague-Dawley-Ratten wurde mit Prednisolon ein reproduzierbares Magenulcusmodell erarbeitet. An diesem Modell wurden Therapeutica untersucht, um deren Eignung, dem Steroidulcus zu begegnen, festzustellen. Lokale Therapeutica wie tierischer, pflanzlicher, synthetischer Schleim und Marktpräparate zeigten sich ineffektiv. Hingegen erwiesen sich in der Reihenfolge ihrer Effektivität Carbenoxolon, DOCA, Aldosterone und Spironolactone als stark wirksam. Ein Elektrolyteffekt schien unwahrscheinlich. In der Diskussion wurde deshalb eingehend die Rolle des Magenschleims als protektive Barriere behandelt. Es wurden die Bindungs- und auch kompetitiven Hemmungsprobleme angesprochen, inwieweit die einen Steroide die anderen Steroide aus ihrer Proteinbindung oder an ihren Receptoren in der Zelle zu verdrängen vermögen, was sich auf die wesentliche Glykoproteinsynthese des Schleims im Magen auswirkt. Unter Prednisolon wird der Schleim minderwertig. Möglicherweise vermögen die anderen Steroide das Prednisolon zu verdrängen, der Magenschleim wird widerstandsfähiger. Soweit aus Tierversuchen ein Schluß erlaubt ist, wurde für die klinische Anwendung eine Empfehlung gegeben.
    Notes: Summary An experimental model inducing reproducibly gastric ulcer in female Sprague-Dawley rats with prednisolon is described. Several substances have been studied with regard to their possible effect to prevent the development of this type of ulcer. Locally applied substances like mucins deriving from animals or plants, synthetic mucin or commercially available antacida proved to be ineffective. A significant ulcer-preventing effect was observed in decreasing order following the application of carbenoxolon, desoxycorticosteronacetate, aldosterone and spironolactone. While there is no evidence that this effect is mediated through electrolytes, the quality of gastric mucus seems to be a very important factor of the protective principle. Prednisolon is thought to have a negative effect on the quality of gastric mucus. The possibility is discussed that some steroids with regard to others exert a competitive action for binding sites with proteins or for their receptors at a cellular level in gastric mucosa, thereby influencing the synthesis of glucoproteins of gastric mucus. In the prednisoloninduced gastric ulcer the protective effect of the substances mentioned above could be explained by this hypothetical competitive mechanism. The possible benefits from the use of these substances as a protective measure in humans is mentioned.
