Rotator cuff muscles lose responsiveness to anabolic steroids after tendon tear and musculotendinous retraction: an experimental study in sheep

Long-standing rotator cuff tendon tearing is associated with retraction, loss of work capacity, irreversible fatty infiltration, and atrophy of the rotator cuff muscles. Although continuous musculotendinous relengthening can experimentally restore muscular architecture, restoration of atrophy and fatty infiltration is hitherto impossible.

Multimodal imaging in macular diagnostics: combined OCT-SLO improves therapeutical monitoring

BACKGROUND: Digital imaging methods are a centrepiece for diagnosis and management of macular disease. A recently developed imaging device is composed of simultaneous confocal scanning laser ophthalmoscopy (SLO) and optical coherence tomography (OCT). By means of clinical samples the benefit of this technique concerning diagnostic and therapeutic follow-up will be assessed. METHODS: The combined OCT-SLO-System (Ophthalmic Technologies Inc., Toronto, Canada) allows for confocal en-face fundus imaging and high resolution OCT scanning at the same time. OCT images are obtained from transversal line scans. One light source and the identical scanning rate yield a pixel-to-pixel correspondence of images. Three-dimensional thickness maps are derived from C-scan stacking. RESULTS: We followed-up patients with cystoid macular edema, pigment epithelium detachment, macular hole, venous branch occlusion, and vitreoretinal tractions during their course of therapy. The new imaging method illustrates the reduction of cystoid volume, e.g. after intravitreal injections of either angiostatic drugs or steroids. C-scans are used for appreciation of lesion diameters, visualisation of pathologies involving the vitreoretinal interface, and quantification of retinal thickness change. CONCLUSION: The combined OCT-SLO system creates both topographic and tomographic images of the retina. New therapeutic options can be followed-up closely by observing changes in lesion thickness and cyst volumes. For clinical use further studies are needed.

Rechtshilfe in Zivilsachen: ausgewählte Auszüge aus der neuen Wegleitung des Bundesamtes für Justiz

Die vorliegenden Beiträge in deutscher und französischer Sprache befassen sich mit Aspekten der Rechtshilfe in internationalen Zivil- und Handelsprozessen. Zur Zustellung von gerichtlichen und aussergerichtlichen Urkunden sowie zur rechtshilfeweisen Beweiserhebung (z. B. Einvernahme mittels Videokonferenz) äussern sich Dr. Alexander Markus sowie Dr. Danielle Gauthey Ladner. Dabei wird insbesondere auf die neue Wegleitung des Bundesamtes für Justiz zu den verschiedenen Haager Übereinkommen eingegangen. Alexander Hilfiker erläutert die Möglichkeiten der Internet-Recherche. Die menschlich vielfach schwierigen Probleme der Kindesentführungen behandeln David Urwyler, Sonja Hauser und Hervé Boéchat. Auf aktuelle Fragen der Anerkennung und Vollstreckung von Zivilurteilen gehen Dr. Samuel Baumgartner und Jean-Marc Wichser ein. Das Thema Vollstreckung von ausländischen Konkurserkenntnissen ist Gegenstand der Beiträge von Prof. Dr. Karl Spühler und von Prof. Dr. Sylvain Marchand.
