Magnetic resonance myelography. Preliminary experience
No full textThree-dimensional (3D) MR Myelography is a new technique using constructive interference steady-state (CISS) sequences, which are characterized by a symmetric flow compensation enhancing CSF signal intensity compared with neural and extradural structures. 3D myelographic projections with different rotation angles are obtained from the 3D dataset with a mathematical algorithm called maximum intensity projection (MIP). Myelographic projections yield a global view of subarachnoid spaces and of root sleeves with no intrathecal contrast agent injection. This study was aimed at assessing the feasibility, the clinical value and the diagnostic accuracy of 3D MR Myelography in comparison with conventional myelography. From September 1992 to January 1994, thirty-five myelograms were performed. The study population consisted of 10 volunteers, 8 patients with traumatic brachial plexus lesions, 7 with herniated disks (4 lumbar and 3 cervical disks), 4 with sacral radicular cysts, 2 with spinal vascular malformations, 3 with extramedullary intradural neoplasms (2 cervical neuromas and 1 cervical meningioma) and 1 with an intramedullary tumor (a conus medullaris ependymoma). All patients underwent SE MRI and conventional myelography (22 lumbar injections, 3 cervical injections of nonionic iodinated contrast agent) followed by CT (CT myelography). This trial demonstrates the feasibility of 3D MR myelography in the study of the cervical and lumbar spine: its results are comparable to those obtained with conventional myelography also in some specific indications like traumatic brachial plexus injuries, where invasive conventional myelography is usually thought to be essential
Ruolo dell’ecografia (US) nella definizione dei criteri di operabilità in pazienti con metastasi linfonodali da carcinoma squamoso del capo e del collo
No full textGunshot wound without entrance hole: where is the trick? - a case report and review of the literature
No full textThe presence at CT scan of more retained bullets than expected could be a very difficult interpretation challenge in the early management of gunshot wounds. The modern non operative management of haemodinamically stable patients without peritonitis requires that the trajectory of the bullet is clearly recognized. This clinical case reporting of a gunshot wound without evident entry hole, allows to discuss the diagnostic and therapeutic implications in the management of gunshot wounds cases with atypical entry and/or exit holes
Variations on the Author
No full text“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

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
