    Notizen: We report the results of a system to test the behavior of the wires of multiwire proportional chambers (MWPC) exposed for 10 min to a uniform force field of about 10 G strength and variable in time in the frequency range 0–2000 Hz. This acceleration will be present when the chambers, mounted inside a cosmic ray spectrometer, are launched by the Space Shuttle towards the NASA Space Station "FREEDOM.'' We have reproduced these conditions in the laboratory by an electronic device and we have found that, after repeated cycles of this treatment, the wire performance remained unchanged. This system can also be used to control the tension of the wires of a MWPC during its normal testing procedure.

    Notizen: Summary A case of primary carcinoma of the esophagus is presented that consisted of poorly differentiated small-cell carcinoma. The patient underwent endoscopic treatment, first with an Nd: YAG laser and, finally, with bougienage and the insertion of a prosthesis in order to relieve dysphagia and improve the nutritional status and quality of life. Even though it is generally uncommon for laser therapy to be chosen as a primary mode of treatment, the results obtained should permit to overcome this lack of confidence in the choice of laser treatment for small-cell carcinoma of the esophagus.

    Thema: Medizin
    Notizen: Abstract Endoscopic insertion of tracheobronchial stents is indicated to achieve patency of the airway in case of malignant or benign obstructing lesions. Until now, the placement of prostheses has required a rigid bronchoscope with specially designed insertion instruments. Self-expanding stents are currently used to treat stenoses of different hollow organs (vessels, urinary tract, gastrointestinal tract, bile duct, respiratory tract). We report the first case of a self-expanding stent implanted in the trachea and right main stem bronchus using flexible videobronchoscope under local anesthesia. The procedure was easy, safe, effective, and well tolerated. No complications occurred.
