Epidemiology, prevention and control of oral diseases in pediatric subjects
Caries and periodontal diseases are a neglected epidemic by millions of
Italians who suffer unnecessarily from them. Both diseases are preventable
and the combination of high prevalence, high morbidity and relative inattention
from the National Health Service (NHS), makes caries and periodontal
disease a significant public health problem. In this perspective, the World
Health Organization and the University of Milan have promoted a national
epidemiological study aimed at a sample of 4, 6 and 12-years-old students
from schools in the North, Central and South of Italy. The study provides for
the administration of a questionnaire to parents and a dental examination
carried out at school by dentists trained by the WHO.
In our town the epidemiological study planning and the survey were carried
out by professors of the School of Specialization in "Pediatric Dentistry"
(Prof. G. Giuliana and Prof. G. Pizzo) supported by specialist dentists from
the same School, calibrated according to the WHO methodology.
The survey was carried out between 2017 and 2019 involving 2701 children
attending schools in the 8 districts of the town.
The parents were sent a letter which explained the nature of the survey
and contained a pre-printed form for the issue of informed consent to participate
in the survey with a questionnaire regarding the family nuclear, the
oral hygiene and eating habits of the minor and the child's previous dental
experiences.
The ICDAS (International Caries Detection and Assessment System) was
used to detect the prevalence of carious lesions. The dentist used for each
child visited a dental mirror and the CPI (Community Periodontal Index)
index for periodontal assessment.
Preliminary results showed that 25.3% of 12-years-old students had gingival
bleeding and 41.1% had tartar.
The caries index (ICDAS) shows us that as early as 4 years, 20% of children
have initial carious lesions, 37% have dentine caries and that 34.38%
have highly destructive caries.
At 12 years, 34.95% had initial carious lesions, 46% had cavities that already
affected dentin and that 42.44% had highly destructive cavities.
The exigence to implement a program of prevention / early treatment of
caries/gingivitis in pediatric subjects living in Palermo, since the first months
of child's life, was born from the data analysis. The project "Un sorriso per
54
tutti i bambini", carried out at the U.O. of "Pediatric Dentistry" of Policlinico
Paolo Giaccone in Palermo, was therefore finalised in order to
1) improve efficiency and effectiveness in the promotion of the oral health
of minors, through the creation of a preventive / assistance route of significant
social health impact;
2) assess the effectiveness of the preventive methodologies adopte
Two-photon imaging of cell-specific fluorophores in transgenic mice â an exploratory tool to study mechanisms of white matter injury
Relatively little is known about specific pathways leading to structural and functional disruption of axons and glial cells in white matter. Because focal cerebral ischemia in humans damages both gray and white matter, an understanding of white matter injury is important in devising potential therapeutic approaches. We have developed a novel brain slice model from transgenic mice under control of cell-specific promoters to understand interactions between oligodendrocytes and axons under high resolution twophoton microscopy. Our data extends over previous findings the vulnerability of oligodendrocytes and axons both in culture and in slice preparations to glutamate toxicity during stroke and hypoglycemia. Conditions as different as stroke, trauma, perinatal brain injury, and multiple sclerosis may share common mechanisms of white matter injury.N/
A Scan-to-BIM Approach for the Management of Two Arab-Norman Churches in Palermo (Italy)
The paper shows the results of the research activities carried out by the Department of Engineering at the University of Palermo (Italy), which assessed the application of the Heritage Building Information Modelling (HBIM) methodology through a Scan-to-BIM approach to two local churches belonging to the medieval period. This project was motivated by a renewed interest from the city administrators towards the conservation of cultural heritage dating back to the Arab-Norman domination in Sicily since one of the two buildings was included in the UNESCO World Heritage Sites list in 2015. The morpho-typological style of the churches has been acquired by high-detailed 3D surveys, which provided the base for two HBIM models suited to render the peculiarity of these buildings at their best. The BIM environment allowed both the geometrical representation of all the architectural elements and their further enrichment with the integration of non-geometric data and semantic signification through a knowledge-based workflow. This process led to a hierarchical organization of two high-accuracy digital replicas and to the creation of a database containing all of the architectural items typical of the Arab-Norman style, aimed to share the awareness of its conservation and to match all of the Cultural Heritage requirements. In the future, the features in this database can be shared with other specialists as reference objects for further studies on cultural heritage sites in the UNESCO list
Behavioural disorders in children and adolescents: A conceptual review about the therapeutic alliance with family and school
Aim: In disruptive behavioral disorders, given the wide range of symptomatic manifestations and the complexity of the sociofamiliar contexts in which they develop, it is now proven that more visible and more stable results can be achieved over time through multimodal and multidimensional interventions. These are accomplished through the integration of psychotherapeutic interventions for the child and parents, counseling interventions for all the various practitioners who come into contact with the child in school, sports, and social settings, through the possibility of organizing multiple settings in patient can be followed by several health professionals such as child and adolescent neuropsychiatrist, neuropsychomotricist, occupation therapist, psychologist
Review about comorbidities of behavioural disorders in children and adolescents: The focus on attention-deficit/hyperactivity disorder
Disruptive behavior disorders (DBD) present high comorbidity rate mainly for opposite-defiant disorders that are frequent among children, adolescents and adults affected by with attention deficit and hyperactivity disorder (ADHD), probably as result of common temperamental risk factors such as attention, distraction, impulsivity. ADHD tend to manifest in about 50% of individuals diagnosed as disruptive behavioral disorders
Application of design for environment principles combined with LCA methodology on automotive product process development: The case study of a crossmember
none4noThe existing Community regulation pushes the carmakers to design eco-sustainability of the vehicle over its life cycle to limit the consequences of the current state and the expected growth of the sector. In this sense, one of the primary aim is reducing raw materials consumption and emissions through the adoption of innovative materials and technologies. This implies the need for the carmakers to integrate Design for Environment (DfE) principles at the early Research and Development (R&D) stage. The article presents a concreate example of integration of DfE and LCA methodology application in the R&D process of a vehicle component produced by Magneti Marelli. The study allowed drawing a balance between the advantages of a lightweight solution with respect to the standard one both from performance and environmental point of view.openMaltese, S.; Delogu, M.; Zanchi, L.*; Bonoli, A.Maltese, S.; Delogu, M.; Zanchi, L.*; Bonoli, A
Environmental assessment of light weighting solutions for automotive components: results, tradeâoff and challenges from real case studies
In the last few decades, the automotive industry is facing the most deal with sustainability programs due to the increase of legislate limits on CO2 emissions and vehicle recyclability rate. Consequently, decisions on products design and development go together with environmental considerations, by starting to look for the employment of lighter materials, thus reducing vehicle mass weight and therefore fuel consumption and CO2 emissions during the dominant operation stage of a vehicleâs life cycle. To tackle this problem many of today automotive components are made of alternative materials like plastics, polymer composites, lighter metals which should lead to weight reduction with the same mechanical performances. Magneti MarelliÂź designs and produces hi-tech systems and components for the automotive sector representing a significant contribution on vehicle mass weight with a roughly 15% portion of incidence. So, in accordance to the environmental regulations, the Company has started to get involved into sustainability programs by focusing attention on the environmental impact of its products. In particular since 2012 Magneti Marelli has included in its mission the âimprovement of environmental and energy performances of products and relatives processes during their whole life cycle, through innovative methodologies that assess the potential impacts in a quantitative wayâ, in this way highlighting the importance of meeting the increasing stakeholdersâ expectations and their requests for transparency in resultsâ communication.
This work addresses the main outcomes stemmed from the several LCA studies carried out over different components in terms of materials and technologies production allowing a wider environmental conscious related to the usage of different materials and manufacturing processes.
Results showed that the materials employed offer the major contribution on the total impact especially for raw materials extraction and production and for the vehicle use phase, with a further substantial difference connected to the use of virgin instead of recycled materials.
The main discussed points will be: i) the trade-off between production phase and use phase impacts; ii) End-of-Life analysis at component level beside the ISO 22628:2002 for the whole vehicle; iii) critical analysis and selection of environmental indicators significant for the automotive sector.
