Clinical management of a peri-implant giant cell granuloma

Purpose. Implant therapy plays an important role in contemporary dentistry with high rates of long-term success. However, in recent years, the incidence of peri-implantitis and implant failures has significantly increased. The peripheral giant cell granuloma (PGCG) rarely occurs in peri-implant tissues and it is clinically comparable to the lesions associated with natural teeth. Therefore, the study of possible diseases associated with dental implants plays an important role in order to be able to diagnose and treat these conditions. Materials and Methods. This report described a 60-year-old Caucasian male who presented a reddish-purple pedunculated mass, of about 2 cm in diameter, associated with a dental implant and the adjacent natural tooth. Results. An excisional biopsy was performed and the dental implant was not removed. Histological examination provided the diagnosis of PGCG. After 19-month follow-up, there were no signs of recurrence of peri-implantitis around the implant. Conclusion. The correct diagnosis and appropriate surgical treatment of peri-implant giant cell granuloma are very important for a proper management of the lesion in order to preserve the implant prosthetic rehabilitation and prevent recurrences

Childhood overweight-obesity and periodontal diseases: is there a real correlation?

Objective. The association between obesity and periodontitis has been extensively investigated in adults but not in young people. The aim of this study was to examine the association between overweight-obesity and periodontal disease in pediatric subjects. Methods. Controlled cross-sectional study involving 100 school children of both gender (50 M and 50 F) between 7 and 12 years of age (mean age 9,19 +/- 1,57). Two groups were formed based on Body Mass Index value: test group with BMI >= 25 Kg/m(2) and control group with BMI <= 24 Kg/m(2). Diet intake and oral hygiene habits were recorded by a specific questionnaire and the periodontal clinical parameters were evaluated. Results. The periodontal examination in the control group revealed a full-mouth plaque score (FMPS) value equal to 21.86% against 50.08% in the group of patients overweight/obese; the full-mouth bleeding score (FMBS) in the control group amounted to 12.7% against 26.24% of test group. No patient in either group included in the study presented a probing pocket depth (PPD) >= 3, so a significant difference regarding this value was not found. Regarding the frequency and quantity of food consumption, the number of obese patients who did not follow a balanced diet largely exceeded the number of normal-weight patients (70 versus 20%). Conclusions. These results focus the attention on the negative impact of obesity on gingival health in young subjects, probably due to a combination of metabolic and inflammatory profiles and the result of a careless attitude towards prevention diseases of the oral cavit

Analisi dei costi e benefici di Google Cloud Platform per algoritmi di Machine Learning

Al giorno d’oggi sempre più aziende richiedono una maggiore flessibilità da poter applicare nell'esecuzione dei propri task computazionali. In questa tesi si vuole svolgere un'analisi dei costi e benefici che Google Cloud Platform (GCP), uno dei leader tra le suite di servizi di cloud computing, offre per l'esecuzione di algoritmi di machine learning. Vengono presentate diverse metodologie con le quali è possibile eseguire questi algoritmi sulla piattaforma in cloud di Google. In particolare, viene approfondito il tema della conteinerizzazione per creare un framework di automatizzazione che riesca ad eseguire algoritmi di machine learning, sfruttando l'efficienza prestazionale dei software container. Si svolge quindi una serie di test ed un confronto, in termini di costi e benefici, tra Google Cloud Platform ed un cloud tradizionale fornito da un provider privato

Lightweight ribs for the strengthening of single leaf vaults undergoing seismic actions.

In this paper the behavior and the collapse mechanism of single leaf vaulted structures undergoing seismic loads are discussed, and an innovative technique based on the use of lightweight ribs is proposed. The efficiency of the solution is verified by means of non linear numerical analyses on a strengthened single leaf vaulted structure. The numeric model is validated through comparison with the results of experimental tests performed on lightweight ribs subjected to cyclic, unsymmetrical load conditions

Mapping of Aedes albopictus abundance at a local scale in Italy

Given the growing risk of arbovirus outbreaks in Europe, there is a clear need to better describe the distribution of invasive mosquito species such as Aedes albopictus. Current challenges consist in simulating Ae. albopictus abundance, rather than its presence, and mapping its simulated abundance at a local scale to better assess the transmission risk of mosquito-borne pathogens and optimize mosquito control strategy. During 2014–2015, we sampled adult mosquitoes using 72 BG-Sentinel traps per year in the provinces of Belluno and Trento, Italy. We found that the sum of Ae. albopictus females collected during eight trap nights from June to September was positively related to the mean temperature of the warmest quarter and the percentage of artificial areas in a 250 m buffer around the sampling locations. Maps of Ae. albopictus abundance simulated from the most parsimonious model in the study area showed the largest populations in highly artificial areas with the highest summer temperatures, but with a high uncertainty due to the variability of the trapping collections. Vector abundance maps at a local scale should be promoted to support stakeholders and policy-makers in optimizing vector surveillance and control
