    Description / Table of Contents: Zusammenfassung In einem Fünfjahreszeitraum (1982–1987) wurden 308 Patienten in einem Alter von 85 und mehr Jahren stationär behandelt. Das Durchschnittsalter betrug 88,2±3,0 Jahre; 199 Patienten (64,6%) wurden operiert, 109 (35,4%) wurden konservativ behandelt. Das Patientengut umfasste hauptsächlich Erkrankungen des Bauchraumes, der arteriellen Gefässe und Traumen. Die Gesamtletalität betrug 19,1%. Die Letalität bei Noteingriffen betrug 30,4%, bei elektiven Operationen 13,1%. 66,9% der Patienten hatten Kreatinin-Erhöhungen, 48,5% einen Diabetes mellitus, 35% eine Anämie. Das prognostisch wichtigste Kriterium war der Röntgenbefund von Herz und Lunge. Die wichtigste Massnahme bei der Behandlung derartig alter Patienten ist eine intensive Operationsvorbereitung.
    Notes: Summary From 1982 to 1987, 308 patients between 85 and 103 years (average, 88.2±3 years) were treated onward; 199 patients (64.6%) were operated on; 109 (35.4%) were treated conservatively. The patient group mainly included abdominal, vascular, and traumatological disorders. The overall mortality was 19.1%. The mortality in emergency operations was 30.4% versus 13.1% in elective operations. Of the patients, 66.9% had elevated creatinine levels; 48.5% diabetes mellitus; 35% anemia. The most important prognostic criterium was provided by X-ray films of the heart and lungs. The most important treatment factor is the intensive preparation of the elder patients for the operation.

    Notes: Abstract Silver dimers and small clusters isolated in rare gas matrices are studied by UV-VIS absorption, emission, and resonance Raman spectroscopy. One, two, and three dimer trapping sites can be identified in Xe, Kr, and Ar matrices, respectively. The sites are identified by computer simulation to be either ofD 4h symmetry, with the molecules aligned in the 〈100〉-direction of thefcc-host lattice, or ofD 2h symmetry, with the molecules occupying single or double vacancies and aligned in the 〈110〉-direction. Low energy external modes of the dimers are observed in the resonance Raman spectra. They probe the guest-host interaction of the molecules and are assigned to librational modes. Trimers and larger clusters are found to be very photosensitive. Three different trimers can be observed in Xe and Kr matrices, respectively. They can be transformed reversibly into each other by laser irradiation. This indicates that probably three corresponding isomers can get stabilized in the two matrices. Further evidence for this interpretation is obtained from emission spectroscopy. Despite the photosensitivity of the trimers it is possible to stabilize the concentration of a particular species by a dual beam technique. Thus we obtained a resonance Raman spectrum of one species in a Xe matrix and a preresonance spectrum of the corresponding species in a Kr matrix.
