Psychoeducational intervention to improve oral assessment in people with autism spectrum disorder, BIO-BIO region, Chile.
2018
Background Lichen planus (LP) is a chronic autoimmune disease that affects the oral mucosa as well as the skin, genital mucosa and other sites. Objective: to evaluate the correlation between oral, genital and cutaneous lichen planus, in a sample of LP patients. Material and Methods This descriptive study reviewed 274 clinical histories of patients, who all presented histological confirmation of lichen planus verified by a pathologist, attending research centers in Barcelona. Results A total of 40 LP patients (14.59%) presented genital lesions. Of 131 patients with cutaneous LP (47.8%), the most commonly affected zones were the body’s flexor surfaces, representing 60.1% of cases. 24% of pati…
Incidence and prevalence of salivary gland tumours in Valparaiso, Chile
2014
Background : To determine the incidence and prevalence of salivary gland tumours in the province of Valparaíso, Chile. Material and Methods : Retrospective review of salivary gland tumours diagnosed between the years 2000 and 2011 from four local pathology services. Information on demographics and histopathology were retrieved from the medical records. Results : The study sample consisted of 279 salivary gland tumours. Prevalence and incidence rates per 100.000 persons were 15.4 and 2.51, respectively. Most of the neoplasms corresponded to benign tumours (70.3%). The most affected gland was the parotid gland. Pleomorphic adenoma was the most common benign tumour (53.8%) and mucoepidermoid c…

2019
Purpose: It aimed at describing the perception of the clinical educational environment by physiotherapy students based on the Postgraduate Hospital Educational Environment Measurement Questionnaire in Chile.Methods: The clinical education environment was evaluated according to the Postgraduate Hospital Educational Environment Measure (PHEEM) by 192 students originally enrolled in the fifth year of the physiotherapy career at 3 different headquarters of the academic institution: Santiago, Viña del Mar, and Concepcion Campus (Metropolitan, Valparaiso, and Bio Bio region, respectively), from March to October 2018. The Cronbach’s α was applied to measure the reliability of the instrument and th…

Prevenir la deserción escolar requiere de un trabajo interprofesional que aborde de manera coordinada los múltiples factores individuales, escolares y estructurales que llevan a un joven a dejar la escolarización formal. Este estudio examina la configuración del trabajo interprofesional que se diseña e implementa en dos Departamentos Municipales de Educación en Chile para abordar la inasistencia y deserción de estudiantes en la educación secundaria creciendo en situación de vulnerabilidad social. Los datos fueron producidos a través de entrevistas en profundidad con la participación de 63 personas, incluyendo a profesionales, apoderados y estudiantes. El modelo del primer caso está orienta…
DNA multigene sequencing of topotypic specimens of the fascioliasis vector Lymnaea diaphana and phylogenetic analysis of the genus Pectinidens (Gastr…
2012
Freshwater lymnaeid snails are crucial in defining transmission and epidemiology of fascioliasis. In South America, human endemic areas are related to high altitudes in Andean regions. The species Lymnaea diaphana has, however, been involved in low altitude areas of Chile, Argentina and Peru where human infection also occurs. Complete nuclear ribosomal DNA 18S, internal transcribed spacer (ITS)-2 and ITS-1 and fragments of mitochondrial DNA 16S and cytochrome c oxidase (cox)1 genes of L. diaphana specimens from its type locality offered 1,848, 495, 520, 424 and 672 bp long sequences. Comparisons with New and Old World Galba/Fossaria, Palaearctic stagnicolines, Nearctic stagnicolines, Old Wo…
Systematics of Mepraia (Hemiptera-Reduviidae): cytogenetic and molecular variation.
2009
The haematophagous insects of the subfamily Triatominae (Hemiptera-Reduviidae) have great epidemiological importance as vectors of Trypanosoma cruzi, the causative agent of Chagas disease. Mepraia was originally described as a monotypic genus comprised of Mepraia spinolai, distributed along coastal areas of northern Chile (from Region I to the Metropolitan Region). Recently, some M. spinolai populations have been ranked as a new species named Mepraia gajardoi. Several populations along the distribution range of the genus were sampled, and genetic differentiation was studied based upon the analysis of three molecular markers: cytogenetics (karyotype and chromosome behaviour during meiosis us…
Prognostic value of immunoexpression of CCR4, CCR5, CCR7 and CXCR4 in squamous cell carcinoma of tongue and floor of the mouth.
2018
Background Diverse studies have evidenced that chemokines can play a critical role in pathogenesis of oral squamous cell carcinoma (SCC). The main chemokines involved in oral carcinogenesis, tumor invasion and metastasis are CCR4, CCR5, CCR7 and CXCR4, and our aim was to evaluate the prognostic value of the immunoexpression of these chemokines in SCC of tongue and floor of the mouth. Material and Methods A retrospective descriptive study of the immunohistochemical expression of CCR4, CCR5, CCR7 and CXCR4 in paraffin-embedded samples of 124 patients with SCC of the tongue and floor of the mouth was performed, considering 98 cases from Brazil and 26 cases from Chile. Associations between vari…

Nuevas pinturas europeas en el MOBAT (Chile)
2018
El MOBAT es uno de los espacios culturales más significados de Chile, por la historia que envuelve su emblemático edificio como por la cantidad y calidad de obras artísticas y piezas históricas que atesora. Sin embargo, desde el terremoto de 2010, permanece cerrado al público y pendiente de ser restaurado y rehabilitado. En este trabajo completamos otros estudios anteriormente publicados sobre la colección de pintura europea que el museo alberga entre sus muros. The MOBAT is one of the most significant cultural spaces in Chile, due to the history that surrounds its emblematic building as well as the quantity and quality of artistic works and historical pieces that it treasures. However, sin…
El tiempo un modo de orden. Una paradoja en la historia como disciplina escolar
2012
Se analiza la contraposición entre duración y medición en la paradoja del tiempo de la Civilización Occidental. A la luz de los planteamientos de Henri Bergson (la duración entendida como flujo) y Galileo, Descartes y Newton (la medición como orden científico y el tiempo medido). El estudio de duración y medición, permite transformar la paradoja del tiempo en un dispositivo, para indagar en el orden escolar. La pregunta principal es, ¿Qué significados sobre el orden escolar y su disciplina permite construir la paradoja del tiempo, concebida como un dispositivo, en la historia como asignatura escolar? Bajo la premisa: El dispositivo de la paradoja del tiempo en la historia como asignatura es…
