Splenic vein thrombosis is a relatively common finding in pancreatitis. Gastric variceal bleeding is a life-threatening complication of splenic vein thrombosis, resulting from increased blood flow to short gastric vein. Traditionally, splenectomy is considered the treatment of choice. However, surgery in necrotizing pancreatitis is dangerous, because of severe inflammation, adhesion, and bleeding tendency. In the Warshaw operation, gastric variceal bleeding is rare, even though splenic vein is resected. Because the splenic artery is also resected, blood flow to short gastric vein is not increased problematically. Herein, we report a case of gastric variceal bleeding secondary to splenic vein thrombosis complicated by necrotizing pancreatitis successfully treated with splenic artery embolization. Splenic artery embolization could be the best treatment option for gastric variceal bleeding when splenectomy is difficult such as in case associated with severe acute pancreatitis or associated with severe adhesion or in patients withhigh operation risk. -

f·~ ... i "'JI 1 ~ ') ..... \ . "' • I ..' .J' Student Convocation on APARTHEID I'm glad to see so many of you out on this cold afternoon to manifest your interest in social justice and particularly in the situation of apartheid, and particularly against the situation of apartheid in South Africa. Let me say first of all, that the issue in question is not whether or not we are against apartheid. l don't know of anyone in America who favors apartheid, certainly not at this University. Apartheid is an evil system, inhuman in its application, and an arrangement that should be eliminated from the face of the earth. The ·issue then is not whether apartheid is evil. l t is. l.Je all recognize that. The real issue is what to do about it and that is not quite as easy as condemning it. As university students, it is important that .. your crusade for social justice be based on studying and understanding, on acknowledgment of the complica- tions of the issue under discussion and Leading towards a solution that will be both intelligent, responsible and effective. Anything Less would be unworthy of university students. It is easy to chant "divestiture now" but l would remind you that complicated questions and complicated problems are 1 -2- not solved by bumper stickers and this is a very complicated question and a very complicated problem. Let me back up and attempt to put it into historical perspective, both with regards to the United States and South Africa as well. Before all of us feel too virtuous, too easily, Let me remind everyone that the United States practiced apartheid for 250 years, dating from the arrival of the first slave. -

Summary of Presentation This Presentation Is an Overview of the Cape Town TV White Spaces Trial
Summary of Presentation This presentation is an overview of the Cape Town TV White Spaces Trial. It provides an overview of the Trial network and the Trial’s accomplishments, with a specific focus on the policy related implications of the results. The presentation describes the technical aspects of equipment, the lab tests conducted on the equipment, the process for developing the database and the techniques used to field check the database results. About The Trial With the support of ICASA, the communications regulator of South Africa, a group of partners implemented a TVWS trial network covering ten schools in the Western Cape over a six month period during 2013. The trial partners include TENET, CSIR Meraka, e-Schools Network, WAPA and Google, with Comsol Wireless Solutions, Carlson Wireless Technologies and Neul as the vendor partners. The goals of the trial was to: Demonstrate that TVWS can be used to deliver affordable broadband and Internet services without interfering with TV reception Increase awareness of the potential for TVWS technology in South Africa and across the continent. About The Network The TVWS network consistc of multiple base stations located at Stellenbosch University’s Faculty of Medicine and Health Sciences in Tygerburg, Cape Town, which deliver broadband Internet service to ten schools within a 10 kilometer radius. The ten schools have been pre- selected based on proximity to the base station, local IT and network support, and other connectivity requirements. Each school receives dedicated 2.5 Mbps service with failover to ADSL in order to prevent downtime during school hours. Visit : TVWS Trial Website . -

Curriculum Vitae Distinguished Professor Heila Lotz-Sisitka Updated July 2018 South African National Research Foundation Chair (Tier 1) Transformative Social Learning and Green Skills Learning Pathways Summary Narrative Overview and Early Career I started my career in primary education, working with young children to expand their learning horizons through creative, critical approaches to learning. This led me into a postgraduate and post-doctoral career trajectory where I was able to expand my interest in primary education to wider forms of education and learning, all of which have centred on how human relations with the environment shape learning and transformation of society towards social justice, sustainability and the common good. My Masters degree focused on critical, democratic and participatory approaches to working with environmental knowledge in learning support materials development with foundation phase teachers in post-apartheid curriculum settings. The project spanned five years, and grew into a national initiative to strengthen curriculum transformation. The study was unanimously recommended for upgrading to PhD by all examiners. This launched me into an active professional career in participation oriented approaches to environment and sustainability education research that has spanned all levels and types of education, including early learning, general education and training, higher education, community education, and conservation education. Most recently I have also become more involved in vocational and workplace learning as the green economy has emerged as a significant driver of potential just transitions in post-apartheid South Africa, and the skills system was found to be largely re-active to environment and sustainability concerns. My current research focusses on global change and social learning systems, with emphasis on transformative social learning and green skills learning pathways. -

Anomalies of the Portal Venous System in Dogs and Cats As Seen on Multidetector-Row Computed Tomography: an Overview and Systematization Proposal
veterinary sciences Review Anomalies of the Portal Venous System in Dogs and Cats as Seen on Multidetector-Row Computed Tomography: An Overview and Systematization Proposal Giovanna Bertolini San Marco Veterinary Clinic and Laboratory, via dell’Industria 3, 35030 Veggiano, Padova, Italy; [email protected]; Tel.: +39-049-856-1098 Received: 29 November 2018; Accepted: 16 January 2019; Published: 22 January 2019 Abstract: This article offers an overview of congenital and acquired vascular anomalies involving the portal venous system in dogs and cats, as determined by multidetector-row computed tomography angiography. Congenital absence of the portal vein, portal vein hypoplasia, portal vein thrombosis and portal collaterals are described. Portal collaterals are further discussed as high- and low-flow connections and categorized in hepatic arterioportal malformation, arteriovenous fistula, end-to-side and side-to-side congenital portosystemic shunts, acquired portosystemic shunts, cavoportal and porto-portal collaterals. Knowledge of different portal system anomalies helps understand the underlying physiopathological mechanism and is essential for surgical and interventional approaches. Keywords: portal system; portal vein; portosystemic shunt; portal hypertension; computed tomography 1. Introduction The portal venous system is essential for the maintenance of the liver mass and function in mammals. The portal system collects blood from major abdominal organs (i.e., gastrointestinal tract, pancreas, spleen) delivering nutrients, bacteria and toxins from the intestine to the liver. In addition, the portal blood carries approximately from one-half to two-thirds of the oxygen supply to the liver and specific hepatotrophic factors [1,2]. The portal blood is detoxified by the hepatocytes and then delivered into the systemic circulation via the hepatic veins and caudal vena cava [3]. -

In this case, the small inferior mesenteric vein drained into a Key Words: Inferior mesenteric vein; Marginal vein; Middle colic vein; Superior tributary of the marginal vein, which joined the superior mesenteric vein via mesenteric vein INTRODUCTION he portal venous system consists of four large veins: the hepatic portal, Tsplenic (SV), superior mesenteric (SMV) and inferior mesenteric (IMV). The SMV collects the venous return from the small intestine, stomach, pancreas, cecum, ascending colon and proximal portion of the transverse colon. The SMV tributaries include the small intestine, right gastro-omental, inferior pancreaticoduodenal, ileocolic, right colic, middle colic (MCV) and marginal (MarV) veins. The IMV receives the blood from the superior rectal, sigmoid and left colic veins, which cover the distal portion of the transverse colon, descending colon, sigmoid colon and superior rectum. According to the description by Thompson in 1890, the portal vein tributaries are categorized into four types [1]. -
