L’e-learning nella formazione dei professionisti della salute : un’introduzione. 1. parte
No full textQuesto lavoro si propone di introdurre i lettori meno esperti alla tematica della formazione a distanza e dell’e-learning nelle professioni sanitarie. Esso è diviso in due parti. Nella Parte I, dopo l’analisi dell’evoluzione storica della formazione a distanza e su supporto informatico, viene esaminato il rapporto che queste forme di didattica innovativa possono e devono intrattenere con la didattica tradizionale. Vengono poi forniti diversi esempi di applicazioni di e-learning nella formazione di base degli operatori sanitari, e numerosi indirizzi Internet per esplorare direttamente la consistenza e la validità di alcune di tali applicazioni
A single-blinded study of the clinical and histopathological features of oral mucosa in patients with chronic graft-versus-host disease

No full textThe prevalence and levels of mutans streptococci (MS) and lactobacilli (LB) in saliva and its possible correlation with dental caries and periodontal conditions was investigated in 473 Italian schoolchildren, 9 and 13 years of age. A clinical examination and sampling of stimulated whole saliva was carried out in the school and oral health was assessed as DMFT and CPITN using the WHO criteria. The saliva samples were frozen in liquid nitrogen and after thawing, cultivated on selective media. To test the influence of cryopreservation, fresh samples from 20 subjects were cultivated. Thirty-five percent of the children were caries-free with a mean DMFT of 1.9 at the age of 13. The majority exhibited healthy periodontal conditions. Salivary MS and LB were identified in 52% and 21% of the children, respectively. The prevalence of MS was higher among the 13-year-olds than the 9-year-olds while no such difference was found regarding LB. There was a statistically positive relationship (P < 0.01) between the levels of MS and LB and both were significantly correlated to caries (P < 0.01). The correlation coefficient of microbial recovery between frozen and unfrozen samples was 0.99. In conclusion, the data provided cross-sectional information of a clear positive relationship between selected micro-organisms in saliva and caries in 9- and 13-year-old children in spite of a relatively low prevalence of the disease. The findings are discussed in a risk selection perspective
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
The effect of levosulpiride in burning mouth syndrome
No full textAIM: This paper evaluated the efficacy of the systemic administration of levosulpiride, an antipsychotic and antidepressant drug, in the management of burning mouth syndrome. METHODS: Forty-four subjects suffering from idiopathic burning mouth syndrome were enrolled in the study. Patients underwent a thorough clinical examination, including salivary flow rate measurements, laboratory tests (complete blood cell counts, blood glucose levels, serum iron and transferrin levels, serum vitamin B(12), and folate levels), patch tests for contact allergy to denture materials, and isolation of Candida species from oral mucosal scrapes. Oral symptoms before and after treatment were assessed using a visual analogue scale. All the patients used systemic levosulpiride (100 mg/daily) for 8 weeks. RESULTS: Of the 39 patients who completed the protocol, none reported complete remission of the oral burning sensation. However, 28 patients reported at least some improvement, and these patients had had oral symptoms for significantly less time than those who reported no improvement. CONCLUSIONS: These preliminary data suggest that levosulpiride is more effective in patients who have recently developed burning/stinging oral sensation
Variations on the Author
Get PDF“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
Miconazole as adjuvant therapy for oral lichen planus : a double-blind randomized controlled trial
Get PDFBackground: Topical steroids are the first choice for the treatment of oral lichen planus (OLP). Antifungal drugs are often employed together with them, to prevent secondary oral candidosis, although it has been suggested anecdotally that they can also be beneficial for OLP itself. Objectives: To compare the effect of clobetasol propionate with and without a topical antifungal drug (miconazole) on the symptoms and extension of OLP. Methods: A randomized, parallel, double-blind trial was conducted at the Unit of Oral Medicine and Pathology of the University of Milan. Thirty-five outpatients with histologically proven OLP were randomly assigned to receive either clobetasol propionate and miconazole, or clobetasol propionate and placebo for 6 weeks. Primary outcomes included symptoms and extension of lesions; adverse effects were also recorded. Results: All the patients who concluded the study (30 of 35) showed clinical and subjective improvement within 3 weeks. The addition of miconazole did not affect in a significant way the signs and symptoms of OLP. No cases of clinical candidosis were seen in the patients taking miconazole, while one-third (five of 15) of the placebo group were affected. Conclusions: Although effective in preventing iatrogenic candidosis, the addition of miconazole to topical steroid treatment does not improve the efficacy of the therapy
