[Bilateral elastofibroma dorsi].
1999
Ein 75 jahriger Patient stellte sich mit seit 2 Jahren langsam grosenprogredienten Raumforderungen unterhalb beider Schulterblatter vor. Anamnestisch bestand ein Zustand nach proximaler Oberarmamputation linksseitig mit folgender prothetischer Versorgung. Klinisch zeigten sich direkt unter den Schulterblattspitzen beidseits 2 faustgrose Tumoren, die fest mit dem tiefer gelegenen Gewebe verwachsen waren. Sowohl magnetresonanztomographisch als auch intraoperativ stellte sich ein infiltratives Wachstum dieser Raumforderungen in die seitliche Thoraxmuskulatur und das Periost der Rippen sowie des Schulterblatts dar, so das ein maligner Tumor vermutet wurde. Histopathologisch zeigte sich Bindegew…
Calidad de la atención al paciente oncológico: Tiempos asistenciales recomendables entre sospecha clínica y definición del plan terapéutico en cáncer…
2012
Fundamento. Determinar tiempos recomendables para el tratamiento desde la sospecha clínica fundada en los procesos asistenciales de cáncer de mama y colorrectal considerando factibilidad y situación personal del paciente. Método. Estudio cualitativo de búsqueda de consenso entre profesionales. Primero, se revisaron mediante 4 sesiones grupales (N=19), los procesos asistenciales de cáncer de mama y cáncer colorrectal y se fijaron los tiempos deseables de ambos procesos. Segundo, mediante una modificación de la técnica Delphi (N=49), se validó la propuesta de tiempos de atención recomendables para cada proceso asistencial. Resultados. La tasa de respuesta en el estudio Delphi fue del 69% en e…
Erweiterte Hemihepatektomie links mit Rekonstruktion der rechten Lebervene bei intrahepatischem cholangiozellulärem Karzinom
2016
Die erweiterte Hemihepatektomie links mit der Resektion der Lebersegmente 1, 2, 3, 4 a/b, 5 und 8 ist eine auch weiterhin sehr herausfordernde Leberresektion, deren Indikation bei gut selektionierten Patienten die Chance auf eine kurative Resektion bei primaren oder sekundaren Lebertumoren mit komplizierter Lage bieten kann. Die Morbiditat und Mortalitat ist gegenuber den nicht erweiterten Leberresektionen erhoht. Eine prazise Bildgebung und genaue Operationsplanung unter Berucksichtigung des verbleibenden Lebervolumens sowie von Einflussfaktoren wie Vorschadigungen des Leberparenchyms durch Chemotherapie oder eine Fibrose/Zirrhose ist hierbei unabdingbar. Notwendig wird dieses operative Vo…
Rice fields as facilitators of freshwater invasions in protected wetlands: the case of Ostracoda (Crustacea) in the Albufera Natural Park (E Spain)
2014
Background: Previous studies have identified rice fields in the Mediterranean region as ‘hot spots’ for the introduction of alien freshwater organisms. Consequently, special attention should be paid when rice fields are located inside or near protected areas for the conservation of native, endangered species. To analyse the relationship between rice field environmental traits and the ecology of aquatic invaders, a study of zoobenthic communities was carried out in JulySeptember 2008 and May-August 2009 in ten rice fields located in the Albufera Natural Park (E Spain), with focus on Ostracoda. Results: A total of nine ostracod species were found including four considered exotic: Candonocypri…
Aquatic pollution may favor the success of the invasive species A. franciscana
2015
The genus Artemia consists of several bisexual and parthenogenetic sibling species. One of them, A. franciscana, originally restricted to the New World, becomes invasive when introduced into ecosystems out of its natural range of distribution. Invasiveness is anthropically favored by the use of cryptobiotic eggs in the aquaculture and pet trade. The mechanisms of out-competition of the autochthonous Artemia by the invader are still poorly understood. Ecological fitness may play a pivotal role, but other underlying biotic and abiotic factors may contribute. Since the presence of toxicants in hypersaline aquatic ecosystems has been documented, our aim here is to study the potential role of an…
What Is the Role of Minimally Invasive Mitral Valve Surgery in High-Risk Patients? A Meta-Analysis of Observational Studies
2016
Background. Minimally invasive valve surgery is related to certain better postoperative outcomes. We aimed to assess the role of minimally invasive mitral valve surgery in high-risk patients. Methods. A systematic literature review identified eight studies of which seven fulfilled criteria for metaanalysis. Outcomes for a total of 1,254 patients (731 were conventional standard sternotomy and 523 were minimally invasive mitral valve surgery) were submitted to meta-analysis using random effects modeling. Heterogeneity and subgroup analysis with quality scoring were assessed. The primary end point was early mortality. Secondary end points were intraoperative and postoperative outcomes and long…
<title>Optical non-invasive monitoring of skin blood pulsations</title>
2005
Time resolved detection and analysis of the skin backscattered optical signals (remission photoplethysmography or PPG) provide rich information on skin blood volume pulsations and can serve for reliable cardiovascular assessment. The single- and multi-channel PPG concepts are discussed in this work. Simultaneous data flow from several body locations allows one to study the heartbeat pulse wave propagation in real time and evaluate the vascular resistance. Portable single-, dual- and four-channel PPG monitoring devices with special software have been designed for real-time data acquisition and processing. The clinical studies confirmed their potential in the monitoring of heart arrhythmias, …
Dane na temat rozprzestrzeniania się inwazyjnego gatunku Oxycarenus lavaterae (Fabricius, 1787) (Heteroptera: Lygaeoidea: Oxycarenidae) w południowo-…
2019
Oxycarenus lavaterae (Fabricius, 1787), the invasive true bug species, were recorded from Poland for the first time in 2014 (SE Poland, Rzeszów; Hebda & Olbrycht, 2016). Since that time it was recorded also in Cieszyn (Western Beskid Mts) and Brzeg (Lower Silesia) in August 2018 (Gierlasiński et al., 2018). In October, November and December 2018 and January 2019, many new populations of this species were reported in south-west regions of Poland (Lower Silesia: Jawor, Legnica, Nysa, Opole, Oława, Racibórz, Świdnica, Wrocław; Upper Silesia: Zdzieszowice) what confirms the species expansion to the north of Poland.
