AUTOMATIC SAGITTAL-TRANSVERSAL MAXILLARY EXPANSION: ORTHOGNATHODONTIC EVOLUTION
No full textThe outcome of daily clinical practice in interceptive orthognathodontics is influenced by the severity of the pathology. It also heavily depends on the paediatric patient's ability to cooperate. The need to choose between dentoalveolar and skeletal expansion using fixed appliances arises from the necessity to achieve a predictable result in the shortest time possible and grant optimal patient growth, even in the absence of cooperation. However, the transposition of the typical three-way steel screw from removable appliances to fixed ones complicates expansion treatments, especially for the patient's parents, forcing the dental professional to perform frequent checks relative to expansion’s activations. The introduction of an automatic one-way nickel-titanium expansion screw in the shape of a crossbow, to be intended as an evolution of the one-way steel screw present in traditional rapid expanders, has paved the way for a new interceptive orthognathodontics paradigm. Daily clinical practice makes skeletal transversal maxillary expansion substantially independent of patient cooperation. In this paper, a new device is presented, with the aim to further refine the concept of independence present in contemporary one-way crossbow-shaped expansion screw appliances, simply introducing three undersized crossbows made from nickel-titanium. This design can exert efficient expansion simultaneously in three directions, making maxillary expansion automatic both sagittally and transversally, minimizing the need for patient cooperation, and reducing parents’ concern

Cholesterol crystal embolization following coronarography. Is that against the surgical procedure? Discussion of one such patient
No full textAuthors report on one patient with cholesterol embolization following cardiac catheterization and coronary by-pass surgery. During the immediate post-operative period, neurological and renal complications occurred because of recurrent cholesterol embolization. One month after surgery the patient died from a sudden neurological coma. Cholesterol crystal embolization appears to be a contra-indication to heart surgery, even in a strongly symptomatic patient, when the spontaneous course of the existing cardiac disease is not life-threatening in the short term
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
