    Description / Table of Contents: Summary It is the task of each medical specialty to develop guidelines for diagnosis and therapies. Examinations done by several specialties should follow a common consensus. A randomized survey at 70 German ENT departments investigated the current position of tracheobronchoscopy and esophagoscopy at each institution. Sixty questionnaires were evaluable. Altogether 8,295 tracheobronchoscopies and 10,404 esophagoscopies were performed. Thirty-six percent of all tracheobronchoscopies and 6% of all esophagoscopies were done with a flexible system. Approximately 58% of all tracheobronchoscopies and 55% of all esophagoscopies were performed for tumor staging. Complications during tracheobronchoscopy occurred in 0.8% of cases and in 0.58% of the esophagoscopies. Using these data an interdisciplinary quality assurance concept was developed for tracheobronchoscopy and esophagoscopy. Current experience has shown that a otolaryngologists in Germany mainly perform rigid tracheobronchoscopy and esophagoscopy. Although endoscopy is mostly done in cases with varied anatomic structures, complications are very rare and comparable to flexible techniques. Greater experience with flexible systems also is to be encouraged in ENT departments.
    Notes: Zusammenfassung Hintergrund: Es muß Aufgabe jedes einzelnen Fachbereichs sein, Leitlinien für die von ihm behandelten Erkrankungen und durchgeführten Untersuchungen zu erstellen. Für fachübergreifende Behandlungen ergibt sich die Forderung nach einem gemeinsamen Konsens. Material und Methoden: Durch eine anonymisierte Umfrage an 70 HNO-Kliniken und Belegabteilungen sollte ein Ist-Stand der Tracheobronchoskopie und Ösophagoskopie in der Hals-Nasen-Ohren-Heilkunde erhoben werden. Ausgewertet werden konnten insgesamt 60 Fragebögen. Unter Berücksichtigung dieser Ergebnisse wurde ein Leitlinienentwurf „Tracheobronchoskopie und Ösophagoskopie” erarbeitet. Ergebnisse: Insgesamt wurden 8295 Tracheobronchoskopien und 10404 Ösophagoskopien durchgeführt; 36% der Tracheobronchoskopien und 6% der Ösophagoskopien erfolgten mit einem flexiblen System. In 58% der Fälle erfolgte die Tracheobronchoskopie zum Tumorstaging, bei der Ösophagoskopie betrug die Anzahl der Untersuchungen zum Tumorstaging 55%. Die Komplikationsrate bei der Tracheobronchoskopie betrug 0,8%, bei der Ösophagoskopie 0,58%. Aufbauend auf diesen Strukturdaten wurde ein interdisziplinär erarbeiteter Leitlinienentwurf in einem Delphiverfahren abgeglichen. Schlußfolgerungen: Die Hals-Nasen-Ohren-Ärzte in Deutschland führen mehrheitlich die starre Tracheobronchoskopie und Ösophagoskopie durch. Obwohl größtenteils bei veränderten anatomischen Strukturen endoskopiert wird, geschieht dies mit Komplikationsraten, die vergleichbar sind mit internationalen Studien bei Einsatz flexibler Systeme. Trotzdem sollte sich der HNO-Arzt vermehrt auch um die flexiblen Techniken bemühen.

    Description / Table of Contents: Summary Although rigid esophagoscopy and tracheobronchoscopy have always been a domain of the ENT surgeon, the development of flexible endoscopes has increased diagnostic and therapeutic indications in clinical practice. Component elements of fiberendoscopes and CCD endoscopes are shown. Techniques in flexible bronchoscopy, flexible esophagoscopy and rhinolaryngoscopy are explained. General and special indications of fiberendoscopy are listed. Possibilities and limitations of flexible bronchoscopy are shown. Flexible techniques for removing foreign bodies of the esophagus and indications for mini-endoscopy are demonstrated. Experience has shown that flexible endoscopy has brought the diagnosis and therapy of tubular organs into a new perspective. Since flexible techniques do not replace rigid ones and complement each another, ENT surgeons must be trained in both techniques.
    Notes: Zusammenfassung Hintergrund: Die Endoskopie von Ösophagus und Tracheobronchialbaum war als starre Technik stets eine Domäne des HNO-Arztes. Mit der Entwicklung der flexiblen Endoskope haben sich die diagnostischen und therapeutischen Anwendungsmöglichkeiten erweitert. Material und Methoden: Dargestellt werden der technische Aufbau der Fieberglasendoskope und der CCD-Endoskope. Der Untersuchungsablauf der Bronchoskopie, der Ösophagoskopie und der Rhinolaryngoskopie werden erläutert. Ergebnisse: Allgemeine und spezielle Indikationen der Fiberendoskope werden aufgeführt, außerdem werden die Möglichkeiten und Grenzen der flexiblen Bronchoskopie diskutiert. Techniken der flexiblen Ösophagusfremdkörperentfernung und Anwendungsbeispiele für Miniendoskope werden erläutert. Schlußfolgerung: Die flexible Endoskopie hat die Diagnostik und Therapie von Hohlorganen in eine neue Dimension gebracht und ihr zu einer weiten Verbreitung verholfen. Flexible Verfahren ersetzen nicht die Starren, sondern sie ergänzen sich gegenseitig und das Repertoire eines HNO-Arztes sollte sich auf beide Techniken erstrecken.

    Notes: Abstract  The adulteration of wine with glycerol is considered to be a problem in European wine-producing countries. The latest control methods are mainly based on the detection of impurities from commercial products, but suffer from the raising efficiency of the purification processes. As there is little chance of being able to identify glycerol from different sources on the basis of a method which uses only one isotope, a multielement approach was tested. Glycerol from wine showed the lowest relative enrichment with D, mainly in position C-2, a relatively high 18O content, and very negative δ13C values, which significantly correlated with those of ethanol from the same wines. The isotopic data of glycerol samples from different sources were in agreement with those given by indices of origin (impurities). These data allowed us to identify the origin of these glycerol samples, i.e. whether they were produced industrially or synthesised by animals or plants. Glycerol of plant origin was most similar to glycerol found in wine. The combination of several isotopic data by discriminance analysis yielded clusters of data obtained from glycerol samples of similar origin. Taking into account the characteristics of possible mixtures, proof that wine has been adulterated depends on the origin and isotope levels of the added compound. This study showed that it is possible to prove that wine has been adulterated with glycerol from other sources when the latter is present at a concentration of 15% of the total glycerol content.

    Notes: Abstract  The application of oxygen isotope analysis to wine water (according to EU regulation no. 822/97) to determine a wine's origin, and check that it has not been adulterated is gaining increasing importance in both laboratories and industry. Using samples of Italian, French and German wines from the EU wine data bank (EU-DB), good agreement between the results from participating laboratories was demonstrated. Close correlations between the oxygen isotope contents of must and related wine water were found for samples from all countries. Based on the results of the δ18O values for EU-DB wines from 1991 to 1996 from Italy, France and Germany, we describe and discuss the main factors which are responsible for the variation of the oxygen isotope ratios of wine water. The examination of spiked samples demonstrated the usefulness of δ18O analysis for the detection of the watering down of wine. The possibility of origin assignment, preferably if the determination of the δ18O value by isotope ratio mass spectrometry (IRMS) is employed together with the determination of the site-specific hydrogen isotope content of wine ethanol by 2H-NMR and the measurement of δ13C values of ethanol by IRMS, is outlined.
