    Notes: Abstract. The purpose of this work was to evaluate the enhancement of different concentrations of gadolinium (Gd), ytterbium (Yb) and iodine in vitro and in vivo. Comparisons were made of the enhancement (HU) of Gd, Yb and iodine in concentrations ranging from 0.1 to 30 mg/ml. In vivo dynamic CT studies were performed in ten dogs with 0.5 M Gd, Yb and iodine. Time-density curves were achieved in aorta and liver. The in vitro studies confirmed a decrease in the enhancement in this order: Gd (120 kV) 〉 Gd (137 kV) 〉 Yb (120 kV) 〉 Yb (137 kV) 〉 iodine (120 kV) 〉 iodine (137 kV). The specific enhancement of Gd was 40.8 (120 kV), of Yb 34.2 and of iodine 29.6 HU. The enhancement of the liver decreases from 21 HU (Gd) to 19 HU (Yb) and 12 HU (iodine). Gd and Yb achieved a higher aortal enhancement than iodine (190 vs 157 HU) All contrast media were well tolerated. Equimolar concentrations of Gd and Yb show a higher in vitro contrast and enhancement than iodine.

    Notes: Background: It has been hypothesized that changes in heating systems and insulation of homes in developed countries have generated an indoor climate favorable to organisms that excrete allergens inducing sensitization and allergic disease. The purpose of this study was to determine the influence of the installation of highly insulated windows and central heating systems on indoor climate, and mite-allergen (Der f 1) and mold spore concentrations. Methods: The bedrooms of 98 apartments were examined before and 7 months (mean) after installation of insulated windows and central heating systems. The air-exchange rate, temperature, and humidity were measured. In settled dust on carpets and mattresses, the number of colony-forming mold spores and the Der f 1 concentration were determined. The inhabitants completed a questionnaire about their lifestyles and housing conditions. Results: The air-exchange rate decreased from geometric mean 0.73 to 0.52 per hour (P=0.029). Temperature (mean 13.4 vs 17.5°C, P〈0.001), and absolute humidity (mean 4.6 g vs 6.2 g H2O/kg air, P〈0.001) increased. Relative humidity remained nearly unchanged (mean 47.6 vs 49.1%). Der f 1 concentrations on carpets (geometric mean 0.65 vs 1.28 μg/g dust, P〈0.001) and mattresses (geometric mean 1.56 vs 2.40 μg/g, P=0.002) increased. Among the fungi that were analyzed, only the thermotolerant species Aspergillus fumigatus increased (geometric mean 20 vs 60 colony-forming units/g carpet dust, P=0.02). Conclusions: The findings of this study suggest that the installation of insulated windows and central heating systems is associated with an increase of Der f 1 concentrations in carpet and mattress dust and A. fumigatus in carpet dust in apartment bedrooms.

    Description / Table of Contents: Summary Purpose: Evalution of MRI in radiotherapy of humeroscapular periarthritis. Patients and methods: Seventy-seven patients with humeroscapular periarthritis prospectively underwent MRI before radiotherapy. Results: Six months after radiotherapy, 34% of the patients had achieved complete pain relief, 35% major pain relief. Twenty percent had only slight improvement and 12% no improvement. Positive correlation of radiotherapy outcome and MRI findings could be shown for acute tendinitis, erosions, and complete and incomplete ruptures of the supraspinatus tendon. Conclusions: Radiotherapy is highly effective in the treatment of humeroscapular periarthritis. The indication can be improved using MRI.
    Notes: Zusammenfassung Fragestellung: Aussagefähigkeit der MRT vor Strahlentherapie der Periarthritis humeroscapularis. Methodik: 77 Patienten mit Periarthritis humeroscapularis wurden prospektiv vor der Strahlentherapie mit einem Linearbeschleuniger MR-tomographisch untersucht. Ergebnisse: 6 Monate nach Beendigung der Radiatio waren 34% der Patienten beschwerdefrei. 35% zeigten eine wesentliche Besserung. 20% waren nur geringfügig gebessert, während bei 12% der Patienten die Symptomatik unverändert fortbestand. Eine positive Korrelation der MR-Befunde mit dem Therapieerfolg bestand bei akuten Tendinitiden, Usuren sowie kompletten und inkompletten Rupturen der Supraspinatussehne. Schlußfolgerungen: Die Strahlentherapie ist neben operativen Verfahren eine weitere wertvolle Methode zur Behandlung der Periarthritis humeroscapularis. Die MRT ist zur Indikationsstellung sinnvoll.
