Evaluation of Surgical Outcome in Rhinoplasty: A Comparison Between Rasp and Osteotome in Dorsal Hump Removal
Full text linkDorsal hump reduction is a crucial point of rhinoplasty, as it has a great impact on the final shape of nasal pyramid. Depending on morphological features of the hump, its removal is usually obtained by the use of an osteotome or a rasp. In our study, we describe a closed rhinoplasty technique performed in 2 groups of patients: the only difference between the groups is the surgical tools used during the dorsal hump removal phase (rasp vs the 5-mm osteotome).We used 2 questionnaires of quality of life (QoL), Nasal Obstruction Symptom Evaluation (NOSE), and Rhinoplasty Outcome Evaluation (ROE) questionnaire, to evaluate postoperative outcome (6 months after surgery).Closed rhinoplasty was performed in 107 patients. Dorsal hump removal was carried out with rasp on 35 patients; while in 72 cases, it was performed using a 5-mm osteotome. All the patients were given 2 copies of NOSE and ROE questionnaires (1 month before surgery and 6 months after surgery) to evaluate postoperative QoL. In our study emerged that the use of osteotome in dorsal hump reduction is associated with a better aesthetic outcome (evaluated by analyzing patients QoL with ROE questionnaire) without any difference between the 2 groups in terms of functional outcome (expressed by NOSE questionnaire), major and minor complications and surgical procedure duration
Cochlear Implant Surgery: How to Fix Receiver/Stimulator Avoiding Extrusion
Full text linkCochlear implant (CI) surgery is generally safe and associated with a limited number of complications, among which the extrusion of the receiver/stimulator (R/S) or the electrode misplacement and migration might require a CI re-implantation. The aim of this pilot study is to describe a new technique to firmly fix the R/S using the Mitek suture anchors system (Depuy Mitek Surgical Products, Inc. Raynham, Massachusetts). We tested two different models and in our experience, the web of suture created with this device can improve the stability of the bond of the R/S to the underlying curved bone surface. So, this system resulted in a less laborious manner keeping low the complication rate
Blood biomarkers of response to concomitant intratympanic and systemic corticosteroids treatment for idiopathic sudden sensorineural hearing loss
No full textPurpose: To evaluate the prognostic value of hematological inflammatory biomarkers in predicting hearing recovery in patients with idiopathic sudden sensorineural hearing loss (ISSNHL) treated with combined systemic and intratympanic corticosteroids. Methods: This retrospective study included 125 patients diagnosed with ISSNHL between 2012 and 2021 who received both oral prednisone and intratympanic methylprednisolone. Clinical data and pre-treatment blood samples were collected. Inflammatory indices including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI) were calculated. Hearing outcomes were classified as complete, partial, or no recovery based on pure tone average (PTA) thresholds. Univariate and multivariable logistic regression analyses were performed to identify predictors of recovery. Results: Of the 125 patients, 33 (26.4%) had no recovery, 50 (40.0%) partial recovery, and 42 (33.6%) complete recovery. Dizziness, current smoking, delayed treatment initiation (> 7 days), elevated triglycerides (≥ 98 mg/dL), and high PLR (≥ 142) were independently associated with a lower probability of hearing recovery. A higher LMR (≥ 3.0) showed a positive trend but did not reach statistical significance in adjusted models. Conclusions: In patients with ISSNHL treated with dual-route corticosteroids, several clinical and hematologic factors, particularly elevated PLR and delayed treatment, are independently associated with reduced odds of hearing recovery. Inflammatory blood markers may serve as accessible prognostic tools to support early risk stratification
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
