Diagnostic Imaging of the Diffuse Hepatic Epithelioid Hemangioendothelioma's Type: A Case Report
We present the case of 35 years old female patient who came to our Institute with an unspecified abdominal pain,
hepatosplenomegaly and a previous alleged diagnosis of Budd-Chiari syndrome. Magnetic resonance imaging (MRI) was crucial to identify a diffuse and infiltrating mass involving the liver in a misleading diagnosis. A discussion about the imaging findings and differential diagnosis of a rare case of diffuse epithelioid hemangioendothelioma (EHE) is provided as follows. MRI was the most important instrument to guide the diagnostic and therapeutic path, helping to define the typical signal intensity of EHE, mainly with a hepatobiliary contrast agent. The differentiating between other primary tumors, however, remains a complicated issue. Our purpose was to highlight the radiologic and MR characteristics of this rare tumor in order to evaluate the diffuse EHE in the diagnostic process

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Portal vein aneurysm: What to know
AbstractPortal vein aneurysm is an unusual vascular dilatation of the portal vein, which was first described by Barzilai and Kleckner in 1956 and since then less than 200 cases have been reported.The aim of this article is to provide an overview of the international literature to better clarify various aspects of this rare nosological entity and provide clear evidence-based summary, when available, of the clinical and surgical management.A systematic literature search of the Pubmed database was performed for all articles related to portal vein aneurysm. All articles published from 1956 to 2014 were examined for a total of 96 reports, including 190 patients.Portal vein aneurysm is defined as a portal vein diameter exceeding 1.9cm in cirrhotic patients and 1.5cm in normal livers. It can be congenital or acquired and portal hypertension represents the main cause of the acquired version. Surgical indication is considered in case of rupture, thrombosis or symptomatic aneurysms. Aneurysmectomy and aneurysmorrhaphy are considered in patients with normal liver, while shunt procedures or liver transplantation are the treatment of choice in case of portal hypertension. Being such a rare vascular entity its management should be reserved to high-volume tertiary hepato-biliary centres
