Dalla malposizione all'inclusione del canino mascellare: diagnosi e previsione di eruzione

obiettivi. Scopo del lavoro è illustrare le più recenti strategie di trattamento intercettivo in una fase di dentizione mista precoce nei pazienti con malposizione del canino permanente mascellare. Materiali e metodi. Dopo aver eseguito la diagnosi di dislocamento del canino è possibile attuare una serie di manovre di terapia intercettiva per favorire la sua eruzione. Sono descritte singolarmente tutte le metodiche di trattamento proposte dalla letteratura, specificando per ogni opzione l’apporto e la validità scientifica. Risultati. Da un’attenta analisi e revisione bibliografica emerge come l’approccio terapeutico nei confronti di una malposizione canina abbia subito un’importante evoluzione nel corso degli anni. Si passa infatti da un metodo di tipo passivo/ osservazionale, che prevede la semplice estrazione del canino deciduo e il monitoraggio radiografico, a interventi di terapia attiva più complessi che possono prevedere l’espansione del mascellare superiore, in associazione o meno alla distalizzazione dei settori latero-posteriori. Discussione. Nei casi di diagnosi precoce, il recupero del canino malposto prevede un nuovo approccio che integra le manovre già descritte con l’estrazione del canino e del primo molare decidui come elementi determinanti nella programmazione ortodontica. Conclusioni. L’obiettivo del trattamento intercettivo del canino mascellare è quello di aumentare le percentuali di successo di eruzione spontanea del canino permanente mascellare diagnosticato in una fase precoce di sviluppo, evitando meccaniche ortodontiche più complesse e biologicamente invasive per il paziente

VIRTUAL DIVING IN THE UNDERWATER ARCHAEOLOGICAL SITE OF CALA MINNOLA

The paper presents the application of the technologies and methods defined in the VISAS project for the case study of the underwater archaeological site of Cala Minnola located in the island of Levanzo, in the archipelago of the Aegadian Islands (Sicily, Italy). The VISAS project (http://visas-project.eu) aims to improve the responsible and sustainable exploitation of the Underwater Cultural Heritage by means the development of new methods and technologies including an innovative virtual tour of the submerged archaeological sites. In particular, the paper describes the 3D reconstruction of the underwater archaeological site of Cala Minnola and focus on the development of the virtual scene for its visualization and exploitation. The virtual dive of the underwater archaeological site allows users to live a recreational and educational experience by receiving historical, archaeological and biological information about the submerged exhibits, the flora and fauna of the place

Different protein source (soybean or faba bean) in postweaning diets for Apennine and Sopravissana (Italian Merino) light lamb: slaughtering performances

While Apennine is an autochthonous medium-large size Italian meat sheep breed well placed in Central Italy, Italian Merino (Sopravissana) is an ancient endangered sheep breed once raised all over Central Italy and now interesting a marginal sheep farming. Due to economical problems in fattening lamb at high weights for Italian farmers (Sanudo et al., 2000; Sarti, 1992), light lamb is one of the main products in Italian meat sheep farming

Treatment and posttreatment effects of a facial mask combined with a bite-block appliance in Class III malocclusion.

Abstract INTRODUCTION: In this cephalometric investigation, we analyzed the treatment and posttreatment effects of an orthopedic protocol for Class III malocclusion consisting of a facial mask combined with a removable bite-block appliance. METHODS: The treated sample consisted of 22 Class III patients treated with the facial mask and bite-block protocol before the pubertal growth spurt (mean age, 8.9 +/- 1.5 years). Treated subjects were evaluated after facial mask and bite-block therapy and at a posttreatment observation in absence of retention. The treated group was compared with a matched control group of 12 untreated Class III subjects. All treated and control subjects were postpubertal at the final observation. Significant differences between the treated and control groups were assessed with the Mann-Whitney U test (P <0.05). RESULTS: Both angular and linear sagittal measurements of the maxilla showed significant improvements during active treatment. Significant improvements of SNA angle, ANB angle, overjet, and molar relationship remained stable during the posttreatment period. No significant effect was found in the mandibular skeletal measures. No significant protraction of the maxillary incisors or retraction of the mandibular incisors was observed. CONCLUSIONS: A bite-block appliance in the mandibular arch with a facial mask enabled effective control of mandibular rotation with progressive closure of the gonial angle. This added to the favorable maxillary outcomes of the treatment protocol. 2010 American Association of Orthodontists. Published by Mosby, Inc. All rights reserved

Diagnostic accuracy of sonohysterography vs hysteroscopy in benign uterine endocavitary findings

OBJECTIVE: To compare diagnostic accuracy of sonohysterography vs hysteroscopy in patients with benign uterine endocavitary findings. PATIENTS AND METHODS: This retrospective study evaluated 202 patients submitted to sonohysterography after transvaginal ultrasound examination suspicious for uterine endocavitary findings. Cytological sample was taken and analyzed from the fluid used to distend the uterine cavity. Of 202 patients enrolled for this study, 86 patients underwent gynaecological surgery, of whom 77 were treated with operative hysteroscopy and 9 with other gynaecological surgical techniques. Statistical analysis was performed to evaluate diagnostic agreement between sonohysterography vs hysteroscopy and cytology vs histology. RESULTS: Diagnostic concordance between sonohysterography and hysteroscopy was significant (k value 0.87). The correlation between cytological and histological findings had a moderate level of concordance (k value 0.49).CONCLUSIONS: Sonohysterography provides a diagnostic accuracy as well as hysteroscopy, therefore, it could be considered an alternative procedure in the diagnosis of benign uterine endocavitary findings

Online user behavioural modeling with applications to price steering

Price steering is the practice of “changing the order of search results to highlight specific products” and products prices. In this paper, we show an initial investigation to quantify the price steering level in search results shown to different kind of users on Google Shopping. We mimic the category of affluent users. Affluent users visit websites offering expensive services, search for luxury goods and always click on the most costly items results at Google Shopping. The goal is checking if users trained in specific ways get different search results, based on the price of the products in the results. Evaluation is based on well known metrics to measure page results differences and similarities. Experiments are automised, rendering large-scale investigations feasible. Results of our experiments, based on a preliminary experimental setting, show that users trained on some particular topics are not always influenced by previous search and click activities. However, different trained users actually achieve different search results, thus paving the way for further investigation

Prediction of Class III treatment outcomes through orthodontic data mining

Summary OBJECTIVE: To determine whether it is possible to predict Class III treatment outcomes on the basis of a model derived from a combination of computational analyses derived from complexity science, such as fuzzy clustering repartition and network analysis
