Periprosthetic femoral fractures: Risk factors and current options to treatment
No full textThe incidence and complexity of the femoral fracture around a previously implanted prosthetic component has been increasing over the last ten years, and treatment can be complex, expensive and associated with an increased risk of local and systemic complications. The surgical treatment options for periprosthetic fractures include open reduction and internal fixation of bone or revision arthroplasty. This review focuses on the current surgical techniques and the pharmacological therapy to provide biological support for the enhancement of bone healing
Posterior lumbar interbody fusion with peek cages: personal experience with 20 patients.
No full textAIM: The use of interbody cages to obtain fusion in the lumbar spine has increased noticeably in the last few years. They are used both with and without posterior stabilization. In our institution a prospective analysis to determine whether PEEK cages can be used as a stand alone device has been performed.
METHODS: The 20 patients with PEEK cages had clinical and radiological follow-up with controls at 1, 3, 6 and 9 months.
RESULTS: The clinical results were considered satisfactory in 75% of the cases. There were no intra-or perioperative complications. There was no displacement of the cages. No signs of unsuccessful fusion were observed.
CONCLUSIONS: Interbody PEEK cages fulfill the objective of stabilizing the treated segment immediately and subsequently. They can be used as stand alone devices with the correct surgical technique and following precise indications

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
