Riesgos asociados al tratamiento ortodóncico a distancia de maloclusiones dentarias García Espona, Juan Ignacio; Perez Torices, Marta; Requena Martínez, María Ángeles; Paredes Gallardo, Vanessa; Menéndez Núñez, Mario; Benitez Hita, Jaime; De Haro Muñoz, Guillermo Descripción resumida de los riesgos asociados a la práctica inadecuada con alineadores de ortodoncia que esperamos sea de utilidad para pacientes, profesionales, colegios y sociedades profesionales e incluso autoridades administrativas y judiciales, que cada día se enfrentan con mayor frecuencia a un tipo de práctica que excede ampliamente los límites deontológicos profesionales.; Short description of the risks associated with inadequate practice with orthodontic aligners that we hope will be useful for patients, professionals, professional associations and societies and even administrative and judicial authorities, who are increasingly faced with a type of practice that exceeds widely the professional deontological limits.

Is there a common pattern of dental specialties in the world? Orthodontics, the constant element García Espona, Juan Ignacio; Garcia Espona, Cristina; Alarcón, José Antonio; García Espona, Eugenia; Fernández Serrano, Javier Background: There is a lack of studies comparing the status of dental specialties worldwide. Therefore, this study aimed to analyze the differences and similarities between the number and types of dental specialties in 31 countries, including every continent, in the world. Materials and methods: Available official documents and webpages from regulatory bodies, official colleges and councils, and dental institutions were collected from 31 countries and analyzed to obtain reliable data on dental specialties. Differences were analyzed using the Lorentz curve and Gini test. Additionally, a cluster analysis was performed to obtain groups of countries with similar patterns in the number and types of dental specialties. Results: A total of 32 different specialties were officially recognized among all the analyzed countries. Orthodontics and oral surgery (100% and 93.1%, respectively) were the two most frequently officially recognized dental specialties worldwide. The total global degree of inequality in the 31 analyzed countries was 42.4%. The Anglo-Saxon countries showed the greatest similarity, approximately 15-fold higher than the European countries. Cluster analysis differentiated six main groups of countries according to the number and types of dental specialties. European countries formed one of the two largest clusters, and the other cluster was of Anglo-Saxon, Asian, African, and several Eastern European countries with a high number of specialties. Conclusions: Officially recognized dental specialties in the different continents and countries show an asymmetric organization. The number, names, and skills of officially recognized dental specialties exhibited significant differences, showing inequalities in their organization. The Anglo-Saxon pattern of dental specialties showed greater equality than the European pattern. Orthodontics was the only constant element among the different patterns.

Effect of hyperglycemia on the antigenic and antibody response to infection by Trichinella spiralis

Effect of hyperglycemia on the antigenic and antibody response to infection by Trichinella spiralis Gomez Garcia, V; Rodriguez Osorio, M; Rodriguez, E; Castillo, M; García Espona, Juan Ignacio The aim of this study was to characterize the effect of hyperglycemia experimentally induced by alloxan on Trichinella spiralis infection. Thirteen days after the intraperitoneal injection of 100mgr/kgr alloxan, animals were infected with about 500 larvae of Trichinella spiralis. The results were compared to a control group of infected animals not receiving alloxan. During the enteral phase of trichinellosis (5th days after infection) hyperglycemia (163±19 vs 105±3 mg/dl, p<0.05) did not affect significantly either the number of adult enteral worms or the serum level of Trichinella circulating antigens. During the muscular phase (47th days after infection) hyperglycemic animals showed a significantly higher number of muscle larvae per gram of diaphragm muscle and a higher antibody titre. From these results we conclude that mild hyperglycemia aggravates Trichinella spiralis infection, mainly during the muscular phase; the effect of hyperglycemia is independent of the diabetogenic agent used (alloxan) which does not influence the degree of Trichinella infection.
