    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.

    Notes: Abstract  The contamination of cereals with field-growing Fusarium species can be a health hazard since Fusarium are known for their ability to produce mycotoxins like zearalenone (ZON) and deoxynivalenol (DON). For this study the formation of ZON was investigated under controlled growth conditions. Ergosterol, as an indicator of fungal growth, and ZON were analysed by HPLC with UV and fluorescence detection respectively. It is shown that ZON is synthesised in the late growth phase of the fungi, which is typical for secondary metabolites. Milling of contaminated wheat shows a reduced content of ZON in fractions of low ash content. Consequently the concentration of ZON in bran, which has a high ash content, was much higher.

    Notes: Abstract Sacral insufficiency fractures develop over a period of time and show time-dependent changes. We report on 15 CT examinations of 5 patients with early-stage insufficiency fractures of the sacrum. In 4 patients only irregular sclerosis without distinct fracture lines was present in 7 of 8 fractures. Of these 4 patients; 3 exhibited intraosseous gas inclusions in a ventral part of a lateral mass; 5 of 8 fractures disclosed a ventral cortical break. When distinct fracture lines had developed in 1 patient, intraosseous vacuum phenomenon had disappeared. Fracture lines evolve over weeks to months and show central bone absorption. The fractures can heal as demonstrated in 4 of 6 fractures in 3 patients, can persist over 1 year without significant changes or can progress to pseudoarthrosis with bone destruction similar to neuropathic joint disease. Intraosseous vacuum phenomena can persist to this stage. Intraosseous vacuum phenomenon is recognized as a potential finding in the early stage of sacral insufficiency fracture, which also is true for irregular sclerosis and ventral cortical disruption.
