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

La patologia orale nel paziente pediatrico. The oral pathology of the pediatric patient
No full textOBJECTIVES The purpose of this paper is to de-scribe and investigate the diag-nostic and clinical aspects of oral diseases that are very common during the paediatric age. They may concern soft tissues, hard dental and bone tissues and may be oral manifestations of systemic diseases. Oral pathologist must be aware of these diseases, some of which must be intercepted early, to be able to implement a timely and decisive treatment plan or send the patient to an ultra-specialist fa-cility that deals with oral pathology. MATERIALS AND METHODS During the paediatric periods, the patients may be affected by several oral lesions. Firstly the simplest congenital lesions, that frequently concern very much the patients themselves and their parents. In many cases it is sufficient to recog-nize the pathology assisting the patients only in the management of their consequence, as in the case of the geographic tongue, or the fis-sured tongue, both clinical situation that expose the patients to mucosal superinfections, by bacteria or yeasts, and that for this reason need a special care by the patient to avoid the onset of such a problem. Children are also frequently affected by infectious diseases. In this compound, there are many situations in which the oral manifestations can precede the systemic diffusion of the infection, as in the case of the Koplik’s spots in the Measles or the strawberry tongue in the scarlatina, their knowledge and early interception is fundamental to avoid the epidemic diffusion of these pathologies keeping away the patient from school, pro-tecting also the other children from suffering of the same disease. Last but surely not least, the pae-diatric patients are also frequently interested by more severe pathol-ogies, such as the neoplasms of the mesenchymal tissues or of the hemopoietic tissues. Whereas the first are extremely destructive and frequently characterized by a very poor prognosis, the latter can be in many cases intercepted in their first phases if the clinicians know that their early manifestation can be localized on the gums, in which abnormal gingival growth and frequent bleedings may suggest the suspicion of such a severe diseases addressing him/her immedi-ately to the specialistic treatment that in many case may lead to the healing, so resulting fundamental in saving lives of the patients. RESULTS AND CONCLUSIONS All the aforementioned situations emphasize greatly the importance of a deep knowledge of the oral pa-thologies in paediatric age. It is evident that the great importance of young people health is only one of the questions that must be relevant for the clinicians. It is fundamental to underline once more that the in-tegrity of teeth or dentition are sole-ly one of the targets, and maybe not the most important, that we must pursue when we face and assume the care of these patients. We must consider that we are responsible of the general health and life of our patients and we cannot ignore the importance of a clear diagnosis of the whole conditions of our patients who really put their lives confidently in our hands. CLINICAL SIGNIFICANCE It is evident that, as for adult patients – and for many reasons – even more than in adults patients, It is therefore necessary for the oral pathologist to integrate their action and knowledge with other medical specialists, to implement, where it is possible, a multidisci-plinary management of important clinical cases recovering the principles of the clinical semeiology, the sole that can enhance the health aspiration of the young patients
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
What is the risk of developing medication-related osteonecrosis in patients with extraction sockets left to heal by secondary intention? A retrospective case series study
No full textPurpose: Tooth and root extractions represent trigger factors for medication-related osteonecrosis of the jaw (MRONJ). The best healing modality for postextraction sockets is still debated. The aim of the study was to estimate the incidence of MRONJ after extractions whose sockets were left to heal by secondary intention. Methods: A retrospective case series study was performed at the Department of Odontostomatological and Maxillofacial Sciences, Sapienza University of Rome. Only patients who underwent nonsurgical extractions, healed by secondary intention, were included in the study. The following parameters were considered: age, sex, pathologies for which bisphosphonates or other drugs related to MRONJ were prescribed, any local or systemic risk factors, type of drug used, route of administration, number of extractions performed, and number of sessions required to complete the extraction program. The main outcome variable was the occurrence of MRONJ. Statistical analysis was performed with SPSS statistical software. Results: Two hundred twenty-one patients were treated from 2007 to 2020 with 639 tooth/root extractions. All patients were treated under antibiotic prophylaxis and with anesthesia without vasoconstrictors. No cases of MRONJ occurred. The mean age of patients was 68.02 ± 11.17. Most of the study sample was represented by women (201 = 90.95%) undergoing treatment for osteometabolic pathologies, most frequently postmenopausal osteoporosis. Alendronate was the most frequently prescribed drug, taken mainly orally. Most patients had local and/or systemic risk factors. Each patient had from 1 to 17 tooth/root extractions (mean = 2.87 ± 2.59) during 1 to 4 sessions (mean = 1.41 ± 0.64). Extractions mainly involved single-rooted teeth/roots, equally distributed between the maxilla and mandible. Conclusions: Secondary intention healing after nonsurgical tooth extraction does not seem to predispose to MRONJ. It can be advisable to perform extractions under antibiotic prophylaxis using anesthetics without vasoconstrictors and chlorhexidine mouth rinses in the 7 following days
Le anomalie vascolari dei tessuti molli del cavo orale
No full textObjectives To examine the vascular anomalies most frequently found in dental practice. Vascular anomalies are diseases characterized by functional and/or morpho-structural alterations of various nature, severity and extension which can affect every type of vessel (arterial, venous or lymphatic) of any caliber or anatomical region. Generally they are congenital and benign though they may cause complications such as ulceration, bleeding, superinfection, functional, and/or aesthetic deficit. Materials and methods Currently, the reference classification is the one adopted by the International Society for the Study of Vascular Anomalies (ISSVA), which distinguishes vascular or vasoproliferative neoplasms, including hemangiomas, from vascular malformations, these latter being further subdivided into low-flow and high bloodstream malformations. The diagnosis of vascular anomalies can not be separated by pathological history and clinical examination of the patient, even if for a certain diagnosis it is necessary to perform instrumental examinations including the echo color doppler ultrasound, a rapid examination, which is repeatable and devoid of ionizing radiation. The treatment involves different techniques, depending on the type of vascular lesion diagnosed; in particular, laser therapy is the most suitable for low-flow anomalies. This technique presents three different approaches: the excisional biopsy being indicated for suspicious lesions which need a histological examination; the transmucousal thermophotocoagulation (TMT) which involves the use of laser in “no contact” mode; and the intralesional photocoagulation (ILP) which uses the laser fiber inside the lesion and is suitable for deepest vascular anomalies. Results and conclusions . According to recent literature and clinical experience, we can say that vascular anomalies are a heterogeneous group of diseases for which treatment is necessary to perform a correct diagnostic clinical-instrumental approach; laser devices, with a wavelength similar to the oxidized hemoglobin, are the gold standard for the treatment of low flow blood abnormalities, both for ease of use and the excellent haemostatic effects
Trattamento di fistola cutanea in unica seduta con terapia endodontica laser assistita. Caso clinico
No full textLa fistola endodontica cutanea,per il suo aspetto clinico è spesso confusa con altri quadri patologici a volte ben più gravi. Una volta effettuata una corretta diagnosi, è sufficiente eseguire un v alido trattamento endodontico del dente respnsabile della lesione; laddove endodobntica è l'origine della fistola, endodontica deve esser ela terapia. Nel caso clinico esposto, alla strumentazione meccanica in Ni-Ti e all'irrigazione con NaOCl ed EDTA abbiamo assovciato l'irradiazione, al termine delle procedure convenzionali, con un laser Md:Yag, la cui azione ha un effetto battericida, al fine di migliorare la decontamniazione del canale radicolare prima di efefttuare l'otturazione canalare nella stessa seduta. la scomparsa della fistola in pochi giorni ed i controlli radiologici nel tempo testimoniano la correttezza e la validità dell'intervento terapeutico proposto
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
