    Notes: A bronchial P cell carcinoid, which was negative for all hormones immunocytochemically tested, showed a globular intracytoplasmic inclusion in almost every cell. The inclusions were not clearly distinguishable using the haematoxylin-eosinsafran procedure; they were best demonstrated with the Masson trichrome stain and the Grimelius technique and were easily detected in 1 μm thick Epon sections as target-like structures. On electron microscopy, they were found to be composed of filamentous aggregates entrapping a few endosecretory granules, which showed degenerative changes. The filaments, 8–10 nm in diameter, lacked any periodicity; they were randomly dispersed in the central area and arranged in broken concentric swirls at the periphery of the inclusions. The globules lacked the tinctorial properties of amyloid, but showed a strong immunostaining for keratin-like proteins. A systematic investigation of 12 APUDomas of bronchial or duodenopancreatic origin, using both light and electron microscopy, identified a few filamentous bodies in one case, a somatostatin cell tumour of ampulla of Vater. In both cases, the structures appeared similar to those previously reported in growth hormone cell pituitary adenomas as well as in a few bronchial or gut carcinoids. Whatever their nature, morphological data suggest that they are related to abnormalities in the secretory function, involving the Golgi apparatus, the endosecretory granules and the microtubular microfilamentous system.

    Description / Table of Contents: Summary A 6-month-old infant was investigated for the first time at the German Heart Institute because of right ventricular insufficiency. The echocardiogram revealed right ventricular dilatation, severe tricuspid valve regurgitation, pulmonary hypertension and abnormal origin of the right pulmonary artery from the ascending aorta. The subsequent catheterization confirmed the diagnosis and the increased pulmonary vascular resistance in the right and left lung. The infant underwent immediate cardiac surgery and re-implantation of the right pulmonary artery in a newly created bifurcation using pericardial patch material. The postoperative course was complicated by persistent pulmonary hypertension, which was successfully treated with inhaled nitric oxide (NO).    The infant was discharged in good cardiorespiratory conditions on the 15th postoperative day.    Conclusion: Right ventricular failure and pulmonary hypertension in infancy can be associated with the rare malformation of abnormal origin of the pulmonary artery from the ascending aorta.
    Notes: Zusammenfassung Wir berichten über ein nunmehr 6 Monate altes Kind, welches im Alter von 2 Monaten durch eine Rechtsherzinsuffizienz unklarer Ursache auffiel. In der transthorakalen Echokardiographie und in der sich unmittelbar anschließenden Herzkatheteruntersuchung wurde eine fehlentspringende rechte Pulmonalarterie (RPA) aus der Aorta ascendens diagnostiziert. Die operative Korrektur erfolgte am Folgetag durch Re-implantation der RPA in den Pulmonalarterienstamm unter Erweiterung der Neo-Bifurkation mit Perikardflicken. Der postoperative Verlauf war komplikationslos.    Schlussfolgerung: Eine unklare RV-Dekompensation geht in einigen seltenen Fällen auf eine abnormal entspringende RPA zurück, die initialen Symptome hängen dabei entscheidend vom Ausmaß der sekundären pulmonalen Hypertension ab.

    Notes: Zusammenfassend ergab sich hinsichtlich der unmittelbaren psychischen Folgen, daß sichGemeinsamkeiten psychischer Störungen weitgehend aus der Beeinträchtigung der Sprache (Sprache hier als wesentliches Organ für die zwischenmenschlichen Beziehungen gemeint) verstehen lassen. Diese Gemeinsamkeiten traten jedoch zurück hinter den Besonderheiten individuell verschiedener Reaktionsweisen, die nach Art und Häufigkeit aufgezählt wurden. Weniger der Kehlkopfverlust war wesentlich für das weitere psychische Verhalten, als vielmehr die prämorbide Persönlichkeit mit ihrer Bereitschaft zu psychischer Kompensation oder Dekompensation und die gegenwärtigen Umweltbedingungen. Dabei war lebensbejahende Anpassung das Normale und wesentlich Häufigere.

    Notes: Abstract Intracranial pseudolymphoma is a rare tumor of the central nervous system. A 35-year-old woman presented with a frontal subcutaneous tumor. Magnetic resonance imaging revealed a left frontal meningeal tumor involving subcutaneous tissue without bone involvement. The mass was completely removed and the histological aspect of all tumor sections was that of a lymphoid hyperplasia with polyclonal proliferation. These findings were characteristic of pseudolymphoma defined as a hyperplasia of follicular and diffuse lymphoid type with assessment of its polyclonality by immunophenotyping on frozen sections, completed by molecular biology techniques.

    Description / Table of Contents: Zusammenfassung Hintergrund: Immer noch stehen Neonatologen und Pädiater einer invasiven kardiologisch-kardiochirurgischen Behandlung von unreifen und sehr kleinen Neugeborenen mit einem angeborenen Herzfehler zurückhaltend gegenüber, da eine hohe Morbidität und Mortalität befürchtet wird. Methode: Retrospektive Analyse der Ergebnisse der in unserer Klinik im Herzkatheterlabor invasiv behandelten Patienten mit einem KG bis 2500 g im Zeitraum von Januar 1994 bis April 1999. Es erfolgten 69 Eingriffe bei 53 Patienten, davon 42 diagnostische Herzkatheteruntersuchungen (HK) bei 29 Patienten sowie 27 Interventionen bei 24 Patienten. ¶   Ergebnisse: In 33% (n=9) der 27 Interventionen konnte eine Operation vermieden (n=7) bzw. auf einen späteren Zeitpunkt ¶(KG≤3000 g, jenseits des 3. Lebensmonats) verschoben (n=2) werden. Dies gelang u.a. durch Dilatation einer Pulmonalklappenstenose (n=4), einer Aortenklappenstenose (n=1) und einer Aortenisthmusstenose (n=1). Eine Stabilisierung der hämodynamischen Situation war bei 14 Patienten möglich – ein antegrader pulmonaler Fluss wurde bei 5, ein effektiver interatrialer Shunt bei 3 Patienten geschaffen, 3 Patienten erhielten einen Stent in den Ductus arteriosus. Bei allen diagnostischen und interventionellen Untersuchungen traten in 9% der Fälle reversible Rhythmusstörungen (4 supraventrikuläre Tachykardien, 2 ventrikuläre Tachyarrhythmien) auf, bei 30% der arteriellen Untersuchungen gab es behandlungsbedürftige Gefäßprobleme. Es gab keine Todesfälle. Schlussfolgerungen: Herzkatheteruntersuchungen und -interventionen können auch bei einem KG≤2500 g mit einer vertretbaren Komplikationsrate durchgeführt werden. Katheterinterventionen können Operationen ersetzen, den erforderlichen Operationszeitpunkt verschieben oder die Ausgangsbedingungen für notwendige Operationen verbessern. Dabei sollten für eine Intervention dieselben Indikationen wie bei den eutrophen Neugeborenen gelten.
    Notes: Summary Background: Pediatricians and neonatologists are still reluctant to consider invasive cardiological or cardiosurgical treatment in low body weight infants because it is believed to considerably increase the risk. The aim of this study was to assess the results and complications of percutaneous transcatheter interventions in infants with a weight below 2.5 kilograms. ¶   Methods: Retrospective analysis was undertaken for all patients with a weight below 2.5 kilograms who underwent cardiac catheterization from 01/1994 to 04/1999. During this time 42 diagnostic catheterizations in 29 patients and 27 transcatheter interventions in 24 patients were performed. ¶   Results: Surgery was replaced or effectively postponed in 9 (33%) out of 27 transcatheter interventions. This was possible for pulmonary stenosis, valvular aortic stenosis and aortic coarctation. A stabilization of the hemodynamic situation was possible in 14 patients. An antegrade pulmonary flow was established in 5, an effective interatrial shunt created in 5 and the arterial duct stented in 3 patients. Only 3 patients had no benefit from the intervention; however, there were no deaths nor hemodynamic complications. Arrhythmias occurred in 9% of all catheterizations and interventions but were transient in all cases. Femoral arterial complications were observed in 30% of all arterial catheterizations. ¶   Conclusion: Diagnostic cardiac catheterization and percutaneous transcatheter interventions can be performed with low mortality and acceptable morbidity in low weight infants. Transcatheter interventions can replace surgery, postpone the necessity for surgery or stabilize the hemodynamic situation prior to surgery.
