An Alternative Approach for the Treatment of Major Aphthosis: Case Report
No full textAn effective treatment for aphthous stomatitis is not still available and its treatment consists only of therapeutic measures to suppress its symptoms. We report a case of a 60-year caucasian woman presented a 16-year history of episodes of multiple major recurrent ulcers in the oral mucosa. Topical application of Oralmedic® caused an improvement of pain, discomfort and healing of the aphthous ulcer. No adverse events or side effects were recorded. Oralmedic® is an effective topical device for the major aphthous ulcers treatmen
Use of Lugol's iodine in oral cancer diagnosis: An overview
No full textEarly diagnosis of oral squamous celi carcinoma (OSCe) still represents an important challenge for clinicians
and patients. Vital staining such as toluidine blue and Lugol's iodine solution, are routinely used in
the ascc detection bur few data exist about the last one. A literature review is made to evaluate the effectiveness
and safety of Lugol's iodine solution in ascc detection and in its margins demarcation. A review
was made of the studies published between 1990 and 2010 in relation to the application of Lugol's iodine
for ascc detection and a better definition of its margins. Data obtained point to the utility and the safety
of Lugol's iodine when employed for detection and margins delineation of ascc and dysplasia. All the
studies consulted found the Lugol's iodine to be effective, cheap and easy to use and they emphasized
its importance in dinical practice. There is need for larger controlled, randomized studies with carefully
selected and standardized outcome measures and patients

No full textObjectives: Measuring peak insertion torque in relation to different bone densities, the
present study seeks to determine whether micromotion at the interface is related to
primary stability achieved by increasing insertion torque.
Material and methods: A total of 120 Ti-Bone implants were placed in fresh bovine bone
samples representing three density categories: hard, normal and soft (HNS). Five groups of
peak insertion torque (20, 35,45, 70 and 100 N'cm) were evaluated in the three bone
density categories noted. Customized electronic equipment connected to a PCwas used to
register the peak and other insertion torque data. A loading device, consisting of a digital
force gauge and a digital micrometer, was used to measure the micromovements of the
implant during the application of 20,25 and 30 N lateral forces. The data were analyzed for
statistical significance by ANOVA and Spearman's rank correlation coefficient tests.
Results: A statistically significant difference between implant micromobility placed with
different levels of torque and in different bone densities was demonstrated by ANOVA.
Spearman's rank correlation coefficient showed a high dependency between the peak
insertion torque and the observed micromovement. Particularly, in soft bone, it was not
possible to achieve more than 35 N'cm of peak insertion torque.
Conclusions: Results showed that increasing the peak insertion torque reduces the level of
implant micromotion. In addition, micromotion in soft bone was found to be consistently
high, which could lead to the failure of osseointegration. Thus, immediate functional
loading of implants in soft bone should be considered with caution
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
Sodium iodide associated to salicylic acid in the topical management of chronic oral candidiasis: a randomized trial
No full textAbstract
Candidiasis is a relevant problem in oral medicine practice. We compared the ~;ntimyootic activity of nystatin with a solution
of sodium iodide associated to salicylic acid (SISA) in the topical management of chronìc candidiasis. Consecutive patients
affected by chronic candidiasis were randomly allocated to SISA (group A) or nystatin (group B). VAS and swab scores were
recorded at the beginning and at the end of the study while the healing index was evaluated at the end of the study only.
Data were analyzed by STATA 10 MP. Forty patients (20 male, 20 female) were randomized. SIAS was as effective as
nystatin in affecting VAS (p greater than 0.05) and swab score (p greater than 0.05). A statistically significant reduction (p
less than 0.05) ofhealing index was observed in both groups. No side effects were reported. SISA topical application, shows
a comparable efficacy to the nystatin in the management of chronic oral candidiasis. Its use could represent an adequate
alternative to the nystatin above ali in the cases of drug-resistance. Further large scale randomized trials are warranted to
confirrn these preliminary findings.
