Le syndrome d Abernethy
No full textLe syndrome d Abernethy désigne un shunt porto-systémique congénital secondaire à une hypoplasie ou à une absence de veine porte. Seulement 61 cas ont été recensés, essentiellement chez des enfants. Les absences congénitales de veine porte sont fréquemment associées à des malformations cardiaques et à des tumeurs hépatiques à type d hyperplasie nodulaire focale. Parmi les complications du syndrome d Abernethy, on distingue des cas d encéphalopathie avec hyperammoniémie, des syndromes hépato-pulmonaires. Après avoir rapporté l observation d un enfant porteur du syndrome d Abernethy, nous reprendrons les principales données de la littérature afin d établir les objectifs d une prise en charge adaptée.NANTES-BU Médecine pharmacie (441092101) / SudocPARIS-BIUM (751062103) / SudocSudocFranceF

Evaporative Roof Cooling - A Simple Solution to Cut Cooling Costs
No full textSince the "Energy Crisis" Evaporative Roof
Cooling Systems have gained increased acceptance
as a cost effective method to reduce the high cost
of air conditioning. Documented case histories in
retrofit installations show direct energy savings
and paybacks from twelve to thirty months.
The main operating cost of an Evaporative
Roof Cooling System is water. One thousand
gallons of water, completely evaporated, will
produce over 700 tons of cooling capability.
Water usage seldom averages over 100 gallons per
1000 ft^2 of roof area per day or 10 oz. of
water per 100 ft^2 every six minutes.
Roof Cooling Systems, when planned in new
construction, return 1-1/2 times the investment
the first year in equipment savings and operating
costs. Roof sprays are a low cost cooling
solution for warehouses, distribution centers and
light manufacturing or assembly areas with light
internal loads. See text "Flywheel Cooling.
Evidence of different underlying processes in pattern recall and decision-making
No full textThe visual search characteristics of expert and novice basketball players were recorded during pattern recall and decision-making tasks to determine whether the two tasks shared common visual–perceptual processing strategies. The order in which participants entered the pattern elements in the recall task was also analysed to further examine the nature of the visual–perceptual strategies and the relative emphasis placed upon particular pattern features. The experts demonstrated superior performance across the recall and decision-making tasks (see also Gorman, A. D., Abernethy, B., & Farrow, D. (2012). Classical pattern recall tests and the prospective nature of expert performance. The Quarterly Journal of Experimental Psychology, 65, 1151–1160; Gorman, A. D., Abernethy, B., & Farrow, D. (2013a). Is the relationship between pattern recall and decision-making influenced by anticipatory recall? The Quarterly Journal of Experimental Psychology, 66, 2219–2236) but a number of significant differences in the visual search data highlighted disparities in the processing strategies, suggesting that recall skill may utilize different underlying visual–perceptual processes than those required for accurate decision-making performance in the natural setting. Performance on the recall task was characterized by a proximal-to-distal order of entry of the pattern elements with participants tending to enter the players located closest to the ball carrier earlier than those located more distal to the ball carrier. The results provide further evidence of the underlying perceptual processes employed by experts when extracting visual information from complex and dynamic patterns
Abernethy Malformation in Children with Focal Liver Lesions
No full textAbernethy malformation is a congenital disease characterized by complete or partial underdevelopment of the portal vein, leading to the occurrence of congenital extrahepatic portosystemic shunts. The anomaly with the absence of the portal vein is detected in 80% of cases in childhood. Patients with this pathology are very frequently examined when detecting space-occupying liver lesions and assuming the presence of a vascular abnormality. The paper describes clinical cases of benign focal liver lesions and Abernethy malformation in children
Management strategy after diagnosis of Abernethy malformation: a case report
No full textAbstract Introduction The Abernethy malformation is a rare anomaly with a widely variable clinical presentation. Many diagnostic dilemmas have been reported. Nowadays, with the evolution of medical imaging, diagnosis can be made more easily, but management of patients with an Abernethy malformation is still open for discussion. Case presentation In this case study, we describe a 34-year-old Caucasian man who presented with a large hepatocellular carcinoma in the presence of an Abernethy malformation, which was complicated by the development of pulmonary arterial hypertension. Conclusion This case underlines the importance of regular examination of patients with an Abernethy malformation, even in older patients, to prevent complications and to detect liver lesions at an early stage.</p
Investment of palliative medicine in bridging the gap with academia: A call to action.
No full textPalliative care and palliative medicine define a relatively new medical discipline that has arisen in response to the need for better approaches to caring for people with advanced life-limiting illnesses. For professional, managerial and cultural reasons, it has evolved largely outside of academic structures. As the discipline has matured, its needs for education, training, intellectual discourse, evidence development and new science have become more apparent. Traditional academia remains sceptical about the role of palliative medicine, and bastions of palliative medicine expertise in universities have been slow to develop. Yet the engagement of the academic sector in palliative medicine has distinct benefits: (1) promoting the exploration of the culture, humanities and science of the discipline; (2) generating evidence to support practice; (3) creating a legion of educators to train a palliative medicine workforce and to inform clinical colleagues of the role of palliative medicine; and (4) providing order and direction to the discipline's development. A roadmap leading to better engagement between palliative medicine and academia is needed. Examples of developments that could help bridge the two domains include: standardisation of terminology and clarification of boundaries of influence; focus on high-quality research that will generate robust evidence to support clinical decision-making; and clear definition of outcomes, with measures that are understandable across medical disciplines

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Significance of CT scan and color Doppler duplex ultrasound in the assessment of Abernethy malformation
No full textAbstract\ud
\ud
Background\ud
Abernethy malformation is a rare congenital vascular abnormality in which the portal vein bypasses the liver and drains directly into the inferior vena cava. Diagnosis is complex and requires good quality imaging methods to identify details in systemic and portal circulation in order to establish diagnostic confirmation and treatment strategy. In this study we highlight the significance of the use of CT scans and Color Doppler Duplex Ultrasound for the diagnosis, treatment and evolution assessment in two adults with Abernethy malformation.\ud

\ud
Case presentation\ud
The diagnosis and the treatment of two patients with Abernethy malformation by CT scan and Color Doppler Duplex Ultrasound is described. One patient was submitted to liver transplantation due to chronic liver disease and multiple nodules diagnosed as adenoma. The other patient had normal liver function and a mild neurological and psychomotor dysfunction, therefore we adopted clinical treatment and close liver parenchyma evaluation and nodule surveillance, using an imaging approach involving intercalating CT scan and Color Doppler Duplex Ultrasound every 6 months. We highlight some important direct and indirect findings of non-invasive imaging methods.\ud

Conclusion\ud
Abernethy malformation requires meticulous image diagnosis to improve treatment and avoid iatrogenic procedures. CT scans and Color Doppler Duplex Ultrasound are both efficient methods for diagnosis, treatment planning and evolution assessment of patients with Abernethy malformation
