[Surgical removal of an osteotribe fractured during the extraction of an embedded third molar. Clinical case].
No full textAlthough rarely reported, the fracture of an osteotribe during the extraction of embedded lower third molars may have severe consequences on the surrounding anatomic structures possibly resulting in permanent damage to the patient. Operators must take special care when choosing instruments, which must comply with particular quality requisites, and during their use in order to avoid intraoperative accidents and subsequent complications. The authors describe a case that was brought to their attention in which the fragment of an osteotribe that had fractured during a previous operation was lodged in the submandibular fossa, penetrating the upper part of the homonymous gland. After the necessary clinical tests, the authors proceeded to remove the fragment thus leading to the resolution of the symptoms reported by the patient.Although rarely reported, the fracture of an osteotribe during the extraction of embedded lower third molars may have severe consequences on the surrounding anatomic structures possibly resulting in permanent damage to the patient.

Gardner's syndrome. A case report [Sindrome di Gardner. Un caso clinico.]
No full textGardner's syndrome is a congenital condition characterised by diffuse intestinal adenomatous polyposis (IAP) associated with maxillary osteomas, odontomas, hypertrophy of the retinal epithelium and skin tumours. It may affect subjects of all ages with equal frequency in males and females. The fact that diffuse adenomatous polyposis, the most serious clinical aspect of the syndrome, is treated surgically, has led to improved survival in patients and, consequently, an increased incidence in associated lesions, particularly maxillary osteomas. A personal case observed at the Odontostoma-tological Clinic of the University of Rome La Sapienza is reported.Gardner's syndrome is a congenital condition characterised by diffuse intestinal adenomatous polyposis (IAP) associated with maxillary osteomas, odontomas, hypertrophy of the retinal epithelium and skin tumours.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
