Capitolo 4. Sindrome di Klinefelter
No full textLa salute orale rappresenta un elemento di fondamentale importanza nello stato di salute generale e contribuisce a garantire una buona qualità di vita della persona. In particolare nei bambini affetti da sindromi cromosomiche e genetiche, l’acquisizione di stili di salute orale adeguati fin dalle primissime età della loro vita rappresenta una chiave di successo nel prevenire l’insorgenza delle patologie orali più diffuse. È bene ricordare che spesso nei pazienti con patologie responsabili di disabilità in età evolutiva, a causa della ridotta collaborazione, le terapie odontoiatriche sono di più difficile esecuzione e la necessità di eseguire le terapie in narcosi con ospedalizzazione può comportare stress psicologici per le famiglie e costi economici elevati per la società. Inoltre, nel bambino con patologia congenita rara, l’insorgenza di patologie odontoiatriche può comportare rischi per la salute generale. Particolari manifestazioni cliniche odontoiatriche sono caratteristicamente associate a singole sindromi, è quindi importante conoscerle per saperle riconoscere e attuare programmi di prevenzione e terapia adeguati.
È quindi fondamentale che questi bambini siano presi in carico sin dalla primissima infanzia presso strutture odontoiatriche a loro dedicate e che l’odontoiatra infantile e l’ortodontista possiedano tutte le conoscenze di base relative al vasto e complesso capitolo delle sindromi genetiche o cromosomiche. Il testo Sindromi genetiche e cromosomiche e patologie del cavo orale costituisce un valido strumento di aggiornamento e un concreto aiuto per tutti gli operatori sanitari che nella loro pratica clinica quotidiana hanno l’obiettivo di promuovere la salute di questi bambini

Effects of rapid maxillary expansion and mandibular advancement on upper airways in Marfan's syndrome children: a home sleep study and cephalometric evaluation.
No full textEvaluation of the effects of rapid maxillary expansion and mandibular advancement using Propulsor Universal Light appliance on the upper airways in Marfan's syndrome children through home sleep studies, Epworth Sleepiness Scale questionnaire, and cephalometric analysis of the upper airways on lateral radiographs.
METHODS:
The study sample consisted of 30 children with Marfan's syndrome, and the control group consisted of 30 untreated and matched children. For Marfan subjects, data were taken at different time points compared to treatment: at T0 (before treatment), T1 (after rapid maxillary expansion), and T2 (after mandibular advancement). For control subjects, data were taken at similar intervals, at three follow-up visits: at T0 (as a starting screening tool), T1 (after approximately 2 years), and T2 (in proximity of the peak skeletal growth).
RESULTS:
Apnea-hypopnea and oxygen desaturations were significantly higher in the study group at T0 and T1 compared with control children. At T2, the values were not significant (p value 0.442 for both apnea-hypopnea index (AHI) and oxygen desaturation index (ODI)). Horizontal airway dimensions were significantly reduced, and vertical airway values were significantly increased in Marfan's syndrome at T0 and T1 but not at T2 (p values at T2: 0.071 for Phw1-Psp, 0.106 for Phw1-Psp', 0.101 for Phw2-Tb, 0.559 for UAL in male and 0.560 for UAL in female).
CONCLUSIONS:
Early rapid maxillary expansion and mandibular advancement using Propulsor Universal Light appliance significantly improved airway patency of Marfan's syndrome children and are strongly encouraged as a routine treatment for both correction of class II malocclusions and prevention of obstructive sleep apnea
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
