    Description / Table of Contents: Zusammenfassung. Intramusculäre Lipome sind seltene benigne Tumore, die wegen ihres nicht abgrenzbaren Wachstums auch als infiltrierende Lipome bezeichnet werden und tief lokalisiert die Skelettmuskulatur befallen. Klinisch imponiert als einziges Symptom eine palpable Raumforderung. Mikroskopisch findet sich zwischen den Muskelfasern monovacuoläres Fettgewebe, welches die Myocyten verdrängt. Im Extremfall kann die präexistente Muskulatur völlig durch Fettgewebe ersetzt werden. Eine sorgfältige pathohistologische Untersuchung aus einer repräsentativen Biopsie ist notwendig, um die Verwechslung mit einem gut differenzierten Liposarkom zu vermeiden. Die verspätete Diagnosestellung, die Ausdehnung und die Lokalisation des Tumors lassen R0-Resektionen oft nicht zu und beeinflussen die Rezidivraten, die zwischen 3 und 62 % angegeben werden [4]. R0-Resektionen sind in Fällen, bei denen postoperativ bedenkliche Funktionsverluste zu erwarten sind, nicht anzustreben. Funktionsstörungen werden langsam eintreten und können weitgehend kompensiert werden, im Gegensatz zu einem sofortigen Funktionsverlust nach radikaler Chirurgie.
    Notes: Summary. Intramuscular lipomas are rare, benign unencapsulated tumors. They are also called infiltrating lipomas because of their infiltrative growth pattern which, deeply localized, seizes the skeleton muscle. The only obvious symptom is a palpable mass. Microscopically, monovacular fat tissue shows up between the muscle fiber. In extreme cases the preexisting muscle can be totally replaced by fat tissue. A precise pathohistological examination is needed to avoid the mistaken diagnosis of a well-differentiated liposarcoma. Late diagnosis, the extent and the localization of the tumor often do not allow for an R0 resection and influence the postoperative recurrence rates, which lie between 3 and 62 %. R0 resections are not desirable when postoperative severe loss of function can be expected. Malfunctions will slowly take place and can greatly be compensated, in contrast to a radical procedure with immediate loss of function.

    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 histoblot immunostaining technique for locating and characterizing amyloidogenic proteins was used to obtain information about the relationship of cerebral ischemia/hypoxia to the accumulation of amyloid β protein (Aβ). We investigated brains of 131 subjects (ages 25–94 years, mean 72 years). Three distribution patterns of Aβ immunoreactivity were identified: (1) colocalization with diffuse and neuritic plaques of Alzheimer's disease (AD) and aging; (2) diffuse punctate deposits in the cerebral cortex in association with small vessel cerebral vascular disease; and (3) cerebral cortical accumulation localized to arterial boundary zones and other regions susceptible to ischemic/hypoxic injury designated "stress-induced deposits" (SID). SID were not identified in tissue sections by immunohistochemical, Congo red or Bielschowsky silver techniques; no histological abnormalities were present in adjacent formalin-fixed tissue sections. SID occurred in subjects with histories of cerebral ischemia, and severe orthostatic hypotension. There was also an association with aging in general and with the incidence of neuritic plaques specifically. These latter findings are consistent with the hypothesis that brain ischemia/hypoxia plays a role in the pathogenesis of AD.

    Notes: Abstract The interdependence of the predicted in vitro residual enzyme activity (PRA), as deduced from the complete genotypes of 64 hyperphenylalaninaemic patients, and parameters for diagnosis of hyperphenylalaninaemic disorders, the fluctuation of the phyenlylalanine (Phe) values during treatment, long-term dietary control during treatment, and a parameter for the outcome of therapy (IQ) was investigated by correlation analysis. A highly significant correlation was found between the PRA and diagnostic parameters, as well as the fluctuation of the Phe values during treatment. Significant correlations were also observed between the parameter describing the fluctuation of the Phe values and the IQ, as well as between the quality of dietary control and IQ. The PRA is a valuable tool for the differential diagnosis of hyperphenylalaninaemic disorders and for the prediction of one aspect of the course of the disease which is related to the intellectual outcome of therapy. The quality of dietary control was independent of the genotype, indicating that the outcome of therapy can be successfully manipulated in spite of the genetic make-up.
