District de technologique et innovation : le cas de l'Arc jurassien suisse / Technological districts and innovation : the case of the Swiss Jura

The Swiss Jura region provides an interesting illustration of the emergence of a new type of spatial production system linked to the appearance of new technologies. This region has recently experienced a transformation of the traditional productive system, based on micro- mechanics and watchmaking, in favour of a system centred on micro-techniques. Such change involves the combination of traditional technologies (micro-mechanics and electro- mechanics) and new technologies (micro-electronics, new materials, optics). This evolution results from the need to adapt to a changing global technological and economic environment. It depends on the existence of specific infrastructures (research and training centres) as well as the development of networks bringing together the different agents of the productive system so as to dispose of the full range of technical and scientific skills essential for the process of innovation. In this context the study shows the importance of the milieu in the emergence of a technological district.L'Arc jurassien suisse offre une illustration intéressante de l'émergence d'un nouveau type de système territorial de production lié à l'apparition des nouvelles technologies. La région en effet vient de connaître une transformation du système productif traditionnel fondé sur la micromécanique et l'horlogerie, vers un système centré sur les microtechniques, qui procède d'une combinaison de technologies anciennes (micromécanique et électromécanique) et nouvelles (micro-électronique, nouveaux matériaux, optique, etc.). Le phénomène de rupture-filiation résulte de la nécessité d'adaptation aux modifications de l'environnement technoéconomique global. Les mutations en cours nécessitent l'existence d'infrastructures spécifiques (centres de recherche et de formation), ainsi que la mise en place de réseaux entre les différents agents du système productif, afin de disposer de l'ensemble des compétences techniques et scientifiques indispensables au processus d'innovation. Dans ce contexte, l'étude met en évidence le rôle du milieu dans l'émergence du district technologique.Pfister Marc, Nemeti Florian.

Spontaneous Fistula and Abdominal Wall Endometriosis Due to Occult Existence of Unicornuate Right Uterus with Rudimentary Non-Communicating Functioning Left Horn

Accurate diagnosis of Müllerian duct anomalies (MDA) remains a clinical challenge even by direct surgical inspection. Although obstetrical complications are more frequent in women with MDA, some subtypes allow normal reproduction, further delaying the diagnosis. Unicornuate uterus with a rudimentary non-communicating functioning horn is a rare form of MDA, susceptible to many gynecologic and obstetric complications such as miscarriages, premature birth, hematosalpinx, endometriosis, and chronic pelvic pain. We present an entire case pictorial assay including preoperative imaging as well as the surgical correction of the uterine anomaly and the associated complication of an occult unicornuate right uterus with rudimentary non-communicating functioning left horn (Class U4aC0V0/ European Society of Human Reproduction and Embryology/European Society of Gastrointestinal Endoscopy Classification) and its natural evolution following a previous incomplete surgical treatment. The patient had an emergency left adnexectomy for hematosalpinx and ovarian endometrioma at her local county hospital. After five years, the patient presented with severe dysmenorrhea and abdominal endometriosis due to blocked retrograde menstruation from a rudimentary, non-communicating functioning horn. Surgical treatment with the resection of the rudimentary uterine horn, together with the abdominal wall endometriosis lesions, was carried out with good outcomes
