Revista médica de Chile , 2011,
Abstract: Background: Celiac disease (CD) is an immune-mediated enteropathy triggered by the ingestion of gluten in genetically susceptible individuals. Its prevalence in Europe and the USA is 0.5 to 1%. Aim: To analyze epidemiological aspects and degree of compliance with gluten-free diet (GFD) among Chilean individuals with CD. Material and Methods: Subjects with confirmed or suspected CD were invited to answer an online survey published on the web at www.fundacionconvivir.cl. The answers were reinforced with a telephone interview. Results: The survey was answered by 1212 subjects (79% females). Median age at diagnosis was 25.8 years (range 1 to 84 years), with a bimodal curve with two peaks at less than 3 years and at 20 to 40 years of age. The diagnosis was made only by serologic markers in 9%, only by intestinal biopsy in 17.5%, and by a combination of both methods in 70%o. Conditions associated with CD were reported by 30%> of subjects and 20%> had relatives with CD. The GFD was strictly adhered to by 70%>, occasionally by 27%> and never by 3%>. Seventy five percent of subjects with a strict adherence to GFD had a favorable clinical response compared with 42%> of those with incomplete or lack of adherence (odds ratio 4.0, 95%> confidence intervals 2.8-5.7p < 0.01). Conclusions: In 30% of respondents, the diagnosis of CD was not confirmed according to international guidelines that require serology and duodenal biopsy. One third of subjects recognized a poor compliance with GFD. Those with a strict adherence to it had a more favorable clinical course. However, 25%> did not experience a clinical improvement despite a strict GFD, a finding which requires further study.

Abstract: gastroesophageal reflux: an attempt to clarify concepts gastroesophageal reflux is one of the subjects in paedriatric gastroenterology that perhaps provokes the biggest controversy. in spite of numerous publications appearing in the last few years, there still exists confusion with respect to theoretical and practical concepts, which frequently results in an inadequate management of patients. the biggest confusion arises from the difficulty in discriminating between physiological and pathological reflux. the existence of numerous techniques for studying reflux, which have been developed in the last few years, indicates that none of them is completely satisfactory, and on the other hand the use of these techniques is not always the best choice. in this article we make a critical appraisal of the subject in relation to aspects theoretical, pathological, diagnostical and therapy, based on the most recent publications in the medical literature
Reflujo gastroesofágico: un intento de clarificar conceptos

Revista chilena de pediatría , 1999,
Abstract: Resumen El reflujo gastroesofágico (RGE) es uno de los temas de gastroenterología pediátrica que tal vez suscite mayor controversia. Pese a las numerosas publicaciones aparecidas en los últimos a os, persiste aún bastante confusión respecto a sus aspectos conceptuales y prácticos, lo que se traduce con frecuencia en un manejo inadecuado de los pacientes que lo presentan. La mayor confusión conceptual deriva de la dificultad de discriminar entre lo que constituye un reflujo fisiológico de uno patológico. La existencia de numerosas técnicas de estudio que se han desarrollado en los últimos a os indica que ninguna de ellas es completamente satisfactoria; por otra parte la utilización de dichas técnicas no siempre es la más adecuada. En el presente artículo se hace una discusión crítica del tema en relación a los aspectos conceptuales, patogénicos, diagnósticos y terapéuticos, en base a las publicaciones más recientes aparecidas en la literatura médica.

Dolor abdominal, dispepsia y gastritis en pediatría: Rol del Helicobacter pylori

Revista chilena de pediatría , 2001, DOI: 10.4067/S0370-41062001000200002
Abstract: helicobacter pylori (h. pylori) is the most common bacterial pathogen of the gastrointestinal tract in humans and also the most common cause of chronic gastritis and is aetiologically associated with duodenal and gastric ulcer, gastric adenocarcinoma and malt lymphoma. the explosive accumulation of published reports makes it necessary to review the concepts of gastritis, recurrent abdominal pain and dyspepsia in children. therefore the aim of this study was to update the concepts and to clarify their relationship with h. pylori and to discuss their validity in order to promote good clinical practice. causative associations between h. pylori infection and other conditions are tenuous and speculative, these conditions include recurrent abdominal pain and non-ulcer dyspepsia. h. pylori is firmly established as a human pathogen because it fulfills each of koch′s postulates as an infective agent causing chronic-active gastritis. indeed h. pylori plays a critical and necessary role in the pathogenesis of chronic -active gastritis in adults. whether h. pylori is a cause of peptic ulcer disease is less well established in children, nevertheless, the evidence for its causation is compelling. there is a strong epidemiological association between h. pylori and peptic ulceration in the absence of drug ingestion in adults. although many people are infected, only a samll proportion will have clinical manifestations of disease. approximately 10% of those infected will develop peptic ulcer disease during their lifetime. infected persons have a 2-6 fold increased risk of developing cancer or malt lymphoma compared to their uninfected counterparts

Abstract: the traditional learning method in human anatomy entails a steady schedule of practice with real material rather than with virtual elements. however, the use of appropriate software and the design and implementation of computer resources to guide the student and allow subsequent review of the dissections has proven to be a useful adjunct to traditional learning methods. the course is based in differents psychopedagogical works like ausubel'asimilation theory of learning , piaget , vigotski. and we have been produce appropiate software like : interactive modular tutorial: is a learning experience with an interactive module, where a teacher acts as a facilitator. on-line dissection room. the images obtained at dissection activities as our anatomy course proceeds, are constantly being published at the catholic university webpages in order to allow their on-line review by the students. club:those students with low marks would be able to join voluntarily our "collaborative environment", where they will be given special duties that would compensate for their deficits, through electronic mail.. the prevailing opinion of medical students was that the software used was an important facilitator in their learning process, particularly when related to complex subjects. a statistical review of the grades - and other indicators of academic performance - obtained by the students over the years showed improvement despite a steady increment in the number of students entering our first year of medical school.
