Benign Thyroid disease: treatment notes
No full textAim
The treatment of benign thyroid disease is a topic widely debated, ranging from "Loboistmectomia" to "Total Thyroidectomy". This study aims to contribute to the thinking on treatment strategies for benign thyroid disease.
Materials of study
35 patients underwent surgical treatment following the pre-surgical diagnosis of benign thyroid disease between 2003 and 2005 at the Complex Unit of General Surgery and Geriatrics at the Second University of Naples (S.U.N.). In 26 cases total thyroidectomies were performed, in 3 subtotal thyroidectomies, in 6 simple lobectomies.
Discussion
Post-surgical progress was optimal in the majority of cases. The large number of total thyroidectomies performed is consistent with the trend favoured by this type of strategy.
When backed by FNA, non-radical surgery can be opted for with greater confidence for single nodules and when surgical risks are high.
The refinement of surgical techniques and directions for the identifying and preparing the recurrent nerve have enabled a radical approach in treating thyroid nodular disease.
Conclusions
In our opinion, for a solitary nodule with residual diseased parenchyma we believe total thyroidectomy should be prescribed. If, however, the residual parenchyma is unharmed a lobectomy may be considered. For a suspected malignant neoplasia or with widespread disease a total thyroidectomy is necessary.
In conclusion, we recommend the individual assessment of each pathology, though we favour total thyroidectomy
Antibiotic prophylaxis in catheter-associated urinary infections.
No full textThis study aimed to assess the usefulness of antibiotic prophylaxis with
Levofloxacin (LVFX) in short and mediumterm catheterisations. This study was
developed to evaluate and confirm the effectiveness and need for prophylaxis in
preventing catheter-associated UTIs, using LVFX at a dose of 250 mg administered
orally to patients who had been subjected to short and medium-term urinary
bladder catheterisation following surgery (3-14 days). The study was designed as
a phase III study with parallel groups, multicentre, randomised, controlled with
a placebo in three groups. The study was double-blind in treatment groups A and B
and single-blind in group C. The study involved the recruitment of 120 patients,
40 for each treatment group. We show two types of results, one based on primary
effectiveness variables and the other on the secondary effectiveness variables.
The group treated with LVFX displayed a greater tendency toward the
negativisation of bacteriuria and pyuria tests than that recorded for the placebo
group, and was essentially comparable to that recorded for the group of patients
treated with Ciprofloxacin. We can thus affirm that LVFX may be useful for
preventing short and medium-term CAUTIs
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
