Non-sutured fixation of the internal receiver-stimulator in cochlear implantation.
Full text linkThe aim of this study is to describe an alternative technique to secure the receiver-stimulator of the cochlear implant to the skull with a tailored flap of periosteum. Other techniques are also reviewed and discussed. 179 consecutive patients were implanted by the same surgeon in a tertiary care setting. Age ranged from 11 months to 74 years. Patients were retrospectively evaluated for device migration. No cases of migration were observed during follow up, ranged 1-99 months with a median of 48 months. The alternative technique proposed is safe and reliable

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
Functional organ preservation after chemoradiotherapy in elderly patients with loco-regionally advanced head and neck squamous cell carcinoma
Full text linkThe aim of the present investigation is to evaluate the outcome after induction chemotherapy and concurrent multi-drug chemoradiotherapy (IC/CCRT) with or without post-chemoradiation neck dissection in medically fit elderly patients with loco-regionally advanced head and neck squamous cell carcinoma (HNSCC). Retrospective study including 44 elderly patients (median age 71 years; range 66-77 years) with previously untreated, inoperable, histologically proven non-metastatic stage III or IV HNSCC. Following one cycle of IC, two cycles of cis-platinum and 5-fluorouracil CCRT with conventional fractionated radiotherapy up to a dose of 66-70 Gy were administrated. A neck dissection was recommended for patients with node metastasis larger than 3 cm regardless of the response to therapy and for patients who had suspected persistent neck disease 8-12 weeks after completing treatment. Salvage surgery was considered for histologically proven persistent or recurrent tumor in the primary site. Time-to-event data were described using Kaplan-Meier actuarial curves. Overall, 37 patients (84.1%) completed the planned treatment. There were no cases of treatment-related deaths. Twenty-nine patients (65.9%) developed severe toxicities with grade 4 toxicity accounting for 22.7%. The median follow-up time in survivors was 41 months. Three-year overall survival, progression-free survival, and functional progression-free survival estimates were 70.9, 67.0, and 57.3%, respectively. In selected medically fit elderly patients with loco-regionally advanced HNSCC, cis-platinum-based chemoradiotherapy can be successfully applied, with moderate adverse events, in attempt to preserve a functional upper aerodigestive tract
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
