Abstract: There search presented here aims to recognize the characteristic components with which academic teacher educators considered memorable are meant, from the perspective of novice teachers of Basic General Education Pedagogy and History and Geography Pedagogy who studied at universities in the south central macrozone of Chile. From a qualitative study of an interpretive nature, results were obtained that show the configuration of four categories of analysis, which expose various characteristics that reveal the importance of the role of the trainer and its impact on the teaching staff.

Resumen: La investigación que aquí se presenta tiene por objetivo reconocer los componentes característicos con que son significados los académicos formadores de profesores considerados memorables, desde la perspectiva de profesores noveles de Pedagogía en Educación General Básica y Pedagogía en Historia y Geografía que cursaron estudios en universidades de la macrozona centro sur de Chile. A partir de un estudio cualitativo de corte interpretativo, se obtuvo resultados que evidencian la configuración de cuatro categorías de análisis, las cuales exponen diversas características que revelan la importancia del rol del formador y su impacto en el profesorado.

Abstract: The objective of this article is to give an account of the state of the art of research on teacher’s identity focused on their experiences in training and in practice. For this, content analysis of a descriptive type is used, in which a total of 20 articles published in the Scopus database from 2014 to 2017 are analyzed. The results indicate that there are multiple studies worldwide, ongoing research that seeks to understand the edges of identity in the various contexts that the teacher’s experiences. Based on the results, we expect to contribute basic knowledge for future studies, to provide insights into what remains to be investigated in this area.

Resumen: El presente artículo tiene como objetivo dar cuenta del estado del arte de la investigación sobre la identidad docente focalizada en experiencias de profesores en formación y en ejercicio. Para ello se emplea análisis de contenido de tipo descriptivo, en el cual se analiza un total de 20 artículos publicados en la base de datos Scopus desde el año 2014 al 2017. Los resultados señalan que existen múltiples estudios a nivel mundial, investigación que se encuentra vigente y que busca comprender las aristas de la identidad en los diversos contextos que vive el educador. A partir de los resultados se espera contribuir con conocimiento de base para futuros estudios, los cuales den luces de lo que falta por investigar en este ámbito.

Abstract Amelogenesis imperfecta (AI) is a group of enamel development disorders that alter the structure and chemical composition of the tissue. There is great variability in the clinical presentation; according to Witkop, AI can be categorized into 14 subtypes, which makes its diagnosis extremely complex. Objective: This study aimed to describe and determine the frequency of clinical and radiographic features and inheritance patterns found in 41 Chilean families diagnosed with diverse types of AI. Material and Methods: We analyzed the clinical records, photographs, pedigrees and radiographs of 121 individuals recruited between 2003 and 2016. All of the information was included in a database that was analyzed using the application Stata 14. Results: The 72 affected individuals had average age of 16 years, and no sex association with the presence of AI was found. The most frequent clinical subtypes were as follows: 43% hypomature, 25% hypoplastic, 21% hypomature/hypoplastic, 7% hypocalcified and 4% hypocalcified/hypoplastic. The number of severely affected teeth was 22, which occurred in the patients with hypocalcified and hypocalcified/hypoplasic AI who presented the highest number of damaged teeth. Caries and periodontal disease were found in 47 and 32% of the patients, respectively. Malocclusions were observed in 43% of the individuals with AI, with open bite being the most frequent. Radiographically, the thickness of the enamel decreased in 51% of the patients, and 80% showed decreased radiopacity of the enamel compared to that of dentin. Autosomal dominant inheritance pattern was found in 37% of the families with hypoplastic AI, and autosomal recessive pattern was present in 56% of the other clinical subtypes, but more frequently in those affected with hypomature and hypocalcified AI. Conclusion: Of the five clinical subtypes, autosomal recessive hypomature, autosomal dominant hypoplastic and autosomal recessive hypomature/hypoplastic AI were the most prevalent subtypes in this group.

Background : The risk of cardiovascular diseases is two to four times higher in diabetic patients. Aim: To study the severity of coronary disease and survival of patients with diabetes mellitus, compared to matched controls without diabetes. Patients and methods: A retrospective review of all coronary angiographies performed at a private hospital. All diabetic patients with coronary lesions over 50% were considered as the index group. Non diabetic patients with coronary artery lesions over 50% and with similar demographic features and risk factors to the diabetic patients group, were studied as controls. A follow up was done reviewing clinical records and by telephone interviews. Mortality was obtained reviewing death certificates. Results: Seventy seven diabetic patients (48 male, mean age 61±10 years and 129 non diabetic subjets (87 males, eman age 61±10 years) were studied. Mean follow up in diabetic and non diabetic patients was 1,270 and 1,340 days respectively. Diabetic patients had a higher frequency of multiple vessel disease than their non diabetic counterparts (69 and 52% respectively, p <0.003). Ejection fraction was 61 and 65% in diabetics and non diabetics. General mortality was 15.5 and 2.3% in diabetics and non diabetic respectively (p <0.01). Cardiovascular mortality was 9.1 and 0.8% in diabetics and non diabetics respectively (p 0.002). Conclusions: Diabetic patients with coronary artery disease have a lower survival and more extensive coronary artery lesions than non diabetic patients with similar age, sex and overall coronary risk (Rev Méd Chile 2004; 132: 331-6).
