    Magnetic resonance pelvimetry in breech presentation at term.

    In almost all previous studies on the policy for breech presentation at term, (X-ray, CT or MR) pelvimetry formed part of the selection procedure for a trial of labour, despite the fact that until now, no prospective studies were available which examined pregnancy outcome as a function of the pelvimetry results obtained before breech delivery. The dilemma of whether elective CS should be preferred to a trial of labour has not been solved by the studies described in this thesis, but it has solved the pelvimetry dilemma in breech presentation a term: it is possible to make better a priori selection of the route of delivery without increasing the overall CS rate by using MR pelvimetry.

    Review of the sedimentary types and stratigraphic positions of the Pleistocene glacial diamictons in the Bełchatów mine (Kleszczów Graben, Central Poland)

    The Quaternary overburden of the giant Belchatów browncoal mine has provided - and still provides - one of the world's best exposures of Pleistocene glacial sediments. The exceptional geological setting - a graben that has been active from the beginning of the Alpine orogeny - provides conditions for preservation of terrestrial glacial deposits that are unique. Outcrops in Pleistocene glaciation-related sediments are commonly small, but the well preserved glacial sediments in the Belchatów mine can be studied without significant interruptions in the walls for several kilometers. In addition, the ongoing exploitation provides an opportunity to obtain a 3-D picture of the faciès and facies transitions that have no counterpart elsewhere. The stratigraphie relationships between a large number of glacial and interglacial units, some of which have a limited lateral extent, could thus be unraveled. It appears that the glacigenic succession comprises at least eight (but probably more) stratigraphie levels with glacial diamictons, thus recording an unmatched history of a glaciated area

    In the Heart of America, 1650

    This small book joins together the creations of two men working three hundred years apart. The tale from the autobiography of Joannis Van Loon, doctor of Rembrandt Van Rijn, tells of his adventures when he traveled to visit Nieuw Amsterdam in the recently settled continent of America in 1650. The drawings and paintings come from the work of independent artist Johannes von Gumppenberg, taken mostly from the time when he lived near the Susquehanna River in Pennsylvania, during the last quarter of the 1900s. Two Johanneses, far apart in time, developed themes that share much in common and hopefully will provide enjoyment for the reader.https://digitalcommons.salve.edu/jvg-books/1004/thumbnail.jp

    The significance of intra-abdominal pressure in neurosurgery and neurological diseases : a narrative review and a conceptual proposal

    Get PDF
    Intra-abdominal pressure (IAP) is a physiological parameter that has gained considerable attention during the last few decades. The incidence of complications arising from increased IAP, known as intra-abdominal hypertension (IAH) or abdominal compartment syndrome in critically ill patients, is high and its impact is significant. The effects of IAP in neurological conditions and during surgical procedures are largely unexplored. IAP also appears to be relevant during neurosurgical procedures (spine and brain) in the prone position, and in selected cases, IAH may affect cerebrospinal fluid drainage after a ventriculoperitoneal shunt operation. Furthermore, raised IAP is one of the contributors to intracranial hypertension in patients with morbid obesity. In traumatic brain injury, case reports described how abdominal decompression lowers intracerebral pressure. The anatomical substrate for transmission of the IAP to the brain and venous system of the spine is the extradural neural axis compartment; the first reports of this phenomenon can be found in anatomical studies of the sixteenth century. In this review, we summarize the available knowledge on how IAP impacts the cerebrospinal venous system and the jugular venous system via two pathways, and we discuss the implications for neurosurgical procedures as well as the relevance of IAH in neurological disorders
