Abstract: Introduction: Emergency radiology (ER) is taught and learned throughout the entire residency. Trainees are exposed to different subspecialties ER cases and through varied imaging techniques. In addition to the “medical expert” domain, residents must develop communication and collaboration skills that will help them during their call schedule. Before they can take night-call, radiology residents must pass an Objective Structured Clinical Examination (OSCE). Purpose: To evaluate communication and collaboration competencies on an ER-OSCE applied to second-year radiology residents. Methods: Specific learning objectives were defined to evaluate communication and collaboration skills in abdominal, musculoskeletal and pediatric ER. Three OSCE stations were designed for this purpose and added to the evaluation instrument in 2017. On each station, resident performance was assessed with a specific template and percentage of goal achievement was calculated. Trainee´s opinion of this new modality was obtained through a perception survey. Results: Three stations were designed, two for the communicator role and one for the collaborator competency. Validity of content confirmed through an expert panel. Percentages of goal achievement on each station varied between 74,7% and 96,6. The new stations were positively evaluated by residents, which valued that competencies other than “medical expert” were being assessed. Conclusion: ER-OSCE allows the appropriate assessment of generic competencies such as communication and collaboration in radiology.

Resumen: Introducción: La Radiología de Urgencias es una unidad de aprendizaje longitudinal a toda la residencia. En ella los residentes se enfrentan a patología de urgencia en distintas modalidades de imagen. Además del dominio cognitivo, los residentes deben desarrollar habilidades de comunicación y colaboración que les permitan enfrentar adecuadamente los turnos de residencia. Previo a incorporarse a los turnos nocturnos, los residentes deben aprobar un Examen Clínico Objetivo Estructurado (ECOE). Propósito: Evaluar competencias de comunicación y colaboración a través de estaciones de ECOE de Radiología de Urgencias aplicado a residentes de 2º año de residencia. Metodología: Se seleccionaron objetivos específicos a evaluar para las competencias de comunicación y colaboración y contenidos de Radiología Abdominal, Osteoarticular y Pediátrica para diseñar tres estaciones de ECOE, las cuales fueron incorporadas en el instrumento de evaluación aplicado el año 2017. Se calcularon porcentajes de logro por estación y tipo de pauta de evaluación. Para evaluar la implementación de las estaciones, se diseñó y aplicó una encuesta de percepción a los residentes. Resultados: Se diseñaron tres estaciones, dos para el rol Comunicador y una para el rol Colaborador. La validez de contenido se aseguró a través de un panel de expertos. Los porcentajes de logro global en las estaciones fluctuaron entre 74,7% y 95,6%. Las estaciones fueron bien evaluadas por parte de los residentes, quienes valoraron la incorporación de competencias diferentes al dominio cognitivo en el instrumento de evaluación. Conclusión: El ECOE permite certificar habilidades transversales como comunicación y colaboración de manera apropiada

Se aplicaron instrumentos como la escala EVPS II de Pender para medir la variable dependiente CPS, y para las independientes como sociodemográficas, conocimientos sobre promoción de salud, percepción del estado de salud y percepción de autoeficacia. Resultados: Son descriptivos de acuerdo con el coeficiente de variación en cada una de las subdimensiones de las conductas: Crecimiento espiritual, Relaciones interpersonales, Responsabilidad en salud, Nutrición, Manejo del estrés y Actividad física. Los factores predictores resultaron de acuerdo con el modelo de regresión múltiple. Conclusiones: La CPS favorables fueron el crecimiento espiritual, las relaciones interpersonales y la nutrición; los predictores que ejercen efecto sobre las CPS se presentaron en función del escalafón docente, edad, área de desempeño adulto anciano, estrato, ingresos y área de desempeño salud mental y psiquiatría.

Abstract Introduction: Health promotion has been a constant concern in the human being. It allows to understand behaviors related to it and orientates towards the generation of health promoting behaviors (HPB) that promote personal well-being. Objective: To determine the predictor factors influencing the HPB of the teachers according to Pender’s health promotion model. Materials and methods: A correlational descriptive design was made with a representative sample of the teachers with current contract during the study. Instruments such as the EVPS II scale of Pender were applied to measure the dependent variable CPS, as well as for the independent ones such as sociodemographic, knowledge on health promotion, perception of health status and perception of self-efficacy. Results: They are descriptive, according to the coefficient of variation in each of the subdimensions of the behaviors: spiritual growth, interpersonal relations, responsibility in health, nutrition, management of stress and physical activity. The predictor factors were based on the multiple regression model. Conclusions: Favorable HPB were spiritual growth, interpersonal relationships and nutrition. Predictors that have effect on HPB were presented on the basis of teacher rankings, age, senior adult performance area, stratum, income and area of performance, mental health and psychiatry.

Resumo Um estudo epidemiológico de cárie usando o sistema ICDAS foi realizado em crianças pequenas colombianas. O objetivo deste estudo foi associar o tempo necessário para o exame clínico da cárie e o risco de cárie em crianças de 1 a 5 anos de acordo com a idade e o risco de cárie e avaliar a autopercepção do comportamento e da dor na criança durante o exame, de acordo com a idade. Após a aprovação do comitê de ética e do consentimento informado dos pais/responsáveis, sete examinadores treinados avaliaram crianças de 1 a 5 anos em creches em condições locais de campo. A experiência de cárie do ICDAS (depiMEmf) foi avaliada da seguinte forma: Epi-depi inicial (ICDAS 1/2 sem secagem ao ar); Moderado-dM (ICDAS 3,4); lesões extensas de dE (ICDAS 5,6); restaurações devido a cárie -f e superfícies/dentes ausentes-m. O risco de cárie foi avaliado com Cariogram®. O comportamento de crianças (Frankl-Behavior-Rating-Scale) e a autopercepção de dor (Escala Visual-Analógica-de-Rostos) durante o exame foram avaliados. O tempo de exame clínico foi registrado com um cronômetro. 592 crianças participaram (1 ano: n = 31; 2 anos: n = 96; 3 anos: n = 155; 4 anos: n = 209, 5 anos: n = 101 ). A prevalência do depiMEmfs foi de 79,9% e a média de 8,4 ± 10,4. A maioria era de crianças com alto risco de cárie (68,9%). A maioria (58,9%) apresentou ≥ comportamento positivo e ≤ autopercepção de dor leve (88,4%). O tempo médio de exame clínico foi em torno de 3,5 min (216,9 ± 133,9 s). Para crianças de 5 anos, correspondeu a 4 min (240,4 ± 145,0 s) vs. 2 min (122,8 ± 80,1 s) para crianças de 1 ano de idade (Kruskal-Wallis; p = 0,00). Para crianças com alto e baixo risco de cárie, foi em torno de 4,3 min (255,7 ± 118,5 s) e 3,3 min (201,3 ± 129,4 s), respectivamente (ANOVA; p = 0,01). Este estudo demonstra que a utilização do sistema ICDAS em crianças pequenas é viável, levando menos de 4 min para o exame clínico sem problemas de autopercepção de comportamento/ dor em crianças.

Abstract A caries-epidemiological study using the ICDASepi-merged system was conducted in Colombian young children. This study aimed at associating the time needed for the clinical examination of caries and caries risk in 1 to 5-year-old children according to age and caries risk, and to assess behavior and child pain self-perception during examination according to age. After IRB approval and given parents/caregivers’ informed consent, seven trained examiners assessed 1 to 5-year olds in kindergartens under local field conditions. ICDASepi-merged caries experience (depiMEmf) was assessed as follows: Initial-depi (ICDAS 1/2 without air-drying); Moderate-dM (ICDAS 3,4); Extensive-dE (ICDAS 5,6) lesions; due-to-caries fillings-f and missing-m surfaces/teeth. Caries risk was assessed with Cariogram®. Child’s behavior (Frankl-Behavior-Rating-Scale) and self-perceived pain (Visual-Analogue-Scale-of-Faces) during examination were evaluated. Clinical examination time was recorded with a stopwatch. A total of 592 children participated (1-yr.: n=31; 2-yrs.: n=96; 3-yrs.: n=155; 4-yrs.: n=209, 5-yrs.: n=101). The depiMEmfs prevalence was of 79.9% and the mean 8.4±10.4. Most were high-caries-risk children (68.9%). The majority (58.9%) showed ≥ positive-behavior and ≤ light-pain self-perception (88.4%). Mean clinical examination time was around 3.5 minutes (216.9±133.9 seconds). For 5-yr. olds it corresponded to 4 minutes (240.4±145.0 seconds) vs. 2 minutes (122.8±80.1 seconds) for 1-yr. olds (Kruskal-Wallis; p=0.00). For high- and low-caries risk children it was around 4.3 minutes (255.7±118.5 seconds) and 3.3 minutes (201.3±129.4 seconds), respectively (ANOVA; p=0.01). This study demonstrates using the ICDAS system in young children is feasible, taking less than 4 minutes for the clinical examination without children behavior/pain self-perception issues.

Abstract Introduction Medical education is currently going through many changes, and Medical Schools must adapt in order to survive. These have to fulfil multiple roles and tasks, with research, teaching, and clinical care as a bottom line. Furthermore, and in many cases, these also include, management, community work, and continuing education courses. Previous studies show that not all of these roles are valued similarly. Objective The objective of this study was to examine the value of teaching perceived by academics from some Medical schools in Chile. Method Semi-structured interviews were conducted with twelve faculty members, all of whom have an active role in teaching. The sampling was intentional and guided by theory. Based on Grounded theory, the data was analysed using open, axial and selective coding. Finally the information was triangulated with literature ad-hoc. Results Three categories emerged from the analysis. First, the “multiple roles and tasks” performed by the faculties. The second is the “personal value of teaching”, and the third, the “institutional value of teaching”. The problem is that, even though teaching is valued, there are other activities, such as research and patient care, that are valued more,. Conclusions These results are multifactorial and they provide evidence that faculties perceive that teaching is relevant, but other activities, like research and clinical work, are valued more The results are similar to those found in the literature, and encourage us to pursue initiatives to rescue and promote the value of teaching, such as protected time for teaching, mentoring, promotion of innovation and excellence, etc.

Resumen Introducción Los académicos de las escuelas de medicina deben cumplir con múltiples roles, como investigación, docencia y asistencia clínica, además de labores de extensión y gestión. Estudios previos muestran que no todas estas labores son valoradas de similar manera. Objetivo Explorar la valoración de la docencia percibida por académicos de una escuela de medicina chilena, a nivel individual, de los pares y de la institución. Método Estudio cualitativo descriptivo que utilizó para el análisis de datos los procedimientos propuestos por la teoría fundamentada, sobre una muestra de 12 académicos que cumplieron criterio de inclusión. Los datos se obtuvieron a través de entrevistas semiestructuradas. Resultados Emergen 3 categorías de análisis: 1) multiplicidad de roles; 2) valoración personal de la docencia, y 3) valoración institucional de la docencia. Destaca que, si bien la docencia es importante, existen otras actividades más valoradas a nivel personal e institucional, como la investigación y la atención de pacientes. Conclusión Los resultados muestran una multiplicidad de factores que afectan a la valoración de la docencia en medicina. Los académicos percibieron la existencia de tareas de mayor connotación académica que la docencia, asociadas a mayores ingresos económicos o al ascenso en la carrera académica, lo que invita a buscar iniciativas institucionales para generar espacios reales de desarrollo académico con el reconocimiento que merece en instituciones que primariamente tienen como misión la formación de las personas.

Objectives. To describe the experience and results of the implementation of a faculty development program for professors of Medicine in the Medical Education Certificate program developed at the School of Medicine, Pontificia Uniersidad Catolica de Chile. Materials and methods. This was a descriptive, cross-sectional, quantitative and qualitative study. The population consisted of all graduates of the program until 2011. A questionnaire with open and closed-ended questions was applied, exploring different levels of impact using the Kirkpatrick evaluation model. Results. Over 97% expressed a high degree of satisfaction (Kirkpatrick level 1). Most respondents reported changes in learning, knowledge and teaching skills (Kirkpatrick Level 2) with statistically significant differences in retrospective pre-post questionnaires 93% reported having improved their teaching performance generally, and 85% in a specific performance (Kirkpatrick Level 3). At level 4 of the Kirkpatrick evaluation model, most perceived an increased interest in teaching and 69% reported being valued more highly at the institutional level. Five categories emerged from the qualitative analysis: value given to teaching and of training in teaching, importance of teaching skills, the contribution of teaching to the professional role, contribution to personal development and strengthening of the academic community. Conclusions. The effects of this faculty development program in medical education have been positive. Professors of Medicine, in addition to improving their teaching performance, perceived changes in personal development, in their role as physicians, in the academic community and in the institution.

Objetivos. Describir la experiencia y resultados de la implementación de un programa de formación en docencia para profesores de Medicina del Diplomado en Educación Médica, desarrollado en la Escuela de Medicina de la Pontificia Universidad Católica de Chile. Materiales y métodos. Estudio descriptivo, transversal, de carácter cuantitativo y cualitativo. La población estuvo compuesta por todos los graduados del programa hasta el 2011. Se aplicó un cuestionario con preguntas abiertas y cerradas explorando diferentes niveles de impacto, utilizando el modelo de evaluación de Kirkpatrick. Resultados. Sobre el 97% expresó un alto grado de satisfacción (nivel 1 Kirkpatrick). La mayoría reportó cambios en el aprendizaje de conocimientos y competencias docentes (nivel 2 Kirkpatrick) con diferencias pre y posretrospectivas estadísticamente significativas. El 93% refirió haber mejorado globalmente su desempeño docente y sobre el 85% en desempeños específicos (nivel 3 Kirkpatrick). En el nivel 4 de Kirkpatrick, la mayoría percibió un incremento del interés por la docencia y 69% reconoció una mayor valoración a nivel institucional. Del análisis cualitativo emergieron cinco categorías: valoración de la docencia y de la formación en docencia, relevancia de las habilidades docentes, aporte de la docencia al rol profesional, contribución al desarrollo personal y fortalecimiento de la comunidad académica. Conclusiones. Los efectos de este programa de formación en educación médica han sido positivos. Los profesores de Medicina, además de perfeccionar sus desempeños docentes, perciben cambios en el desarrollo personal, en su rol de médico, en la comunidad académica y en la institución.

Background: In medical education there has been increasing emphasis on faculty development programs aimed at the professionalization of teaching and increasing students' learning. However, these programs have been shown to have an impact beyond improvement in teaching skills. The medical school of the Pontificia Universidad Católica de Chile (EMUC) has been running a faculty development program (DEM) since 2000. Aim: To explore the perception of graduates on the effects of having participated in DEM on their development as teachers and clinicians. Material and Methods: Using an exploratory, descriptive and qualitative design, the 79 teachers who graduated from DEM from 2004-2008 were sent a questionnaire containing three open questions. Their answers were analyzed using the Constant Comparative Method of Qualitative Analysis of Glaser and Strauss by four researchers. Results: Faculty development, becoming a better clinician, personal development, appreciation of the value of teaching and strengthening of the academic community were the five categories that emerged from the answers. Graduates felt that, besides learning new educational skills, they changed their attitude towards teaching. DEM was perceived as facilitating self-awareness and refection about the graduates' role as doctors and teachers. The graduates also valued meeting other faculty. Conclusions: Faculty development programs can have an impact far beyond the learning objectives. The planning and design of programs contributes to their wider impact. This should be taken into consideration in the design, planning, and evaluation of faculty development programs. Care should be taken to protect time for participation, refection and for interaction with other academics.

Background: Since 2000, the medical school of the Catholic University of Chile (EMUC) has offered courses for its faculty as part of a Diploma in Medical Education (DEM). However by 2009, 41% of faculty had never taken any courses. Aim: To explore the reasons why faculty choose not to participate in these courses. Material and Methods: Semi-structured interviews to seven faculty members, all of whom have an active role in teaching but who had not taken any DEM courses. The sampling was intentional and guided by theory. Based on Grounded theory, the data was analyzed using open, axial and selective coding. Results: Three categories emerged from the analysis. First, the characteristics of a "good teacher" and what it means to be a good teacher. Second, the current status of teaching. Third, the barriers to participate in courses of DEM. Non-attendance is multifactorial; teaching is seen as a natural skill that is difficult to be trained, teaching has a lower priority than other activities, and there are many barriers perceived for attendance. Conclusions: With these results we developed a model to explain the reasons why faculty choose not to participate in these courses. The lower value of teaching and the multiple roles that teachers have, are highlighted.

Background: Narrative medicine has showed to be a powerful instrument to reinforce relationships, identity, and self-knowledge among health professionals. Subjective issues have been recently recognized as relevant for faculty development in addition to the technical aspects. Since 2006 a creative writing workshop has been included as part of the Diploma in Medical Education at the medical school of the Pontificia Universidad Católica de Chile. Aim: To describe the experience and results of the creative writing workshop (2006-2010). Material and Methods: Descriptive and retrospective study with a qualitative and quantitative design. Thirty-six teachers of the School of Medicine attended a 12-hour workshop. The Kirkpatrick model for evaluation of educational outcomes was used to report the data obtained in the course evaluation survey and in the stories produced. Results: There were positive results at the four levels of Kirkpatrick evaluation model. The learning objectives of the workshop were achieved and 83 stories were created, compiled and published. Conclusions: The creative writing workshop can provide faculty with protected time for reflective practice about academic experiences and produce educational outcomes at different levels of the Kirkpatrick model.

Background: Few medical teaching institutions provide faculty development in curriculum development to program directors of medical specialties (PD), despite the increased demand for renewal of residency programs and the evaluation of outcomes. Aim: To describe and evaluate a training program in curriculum development for PD developed in 2008 and 2009. Material and Methods: Thirty PD attended an on campus course of fifteen hours. Evaluation was done using Kirkpatrick model through an end-of-course questionnaire, a retrospective pre/post self-assessment test of skills, the assessment of learning and the final projects developed by PD. Results: All PD finished the course and answered the questionnaire. In level 1 (Reaction), 100% reported high satisfaction and would recommend it highly to others, with perceived mean achievement of course objectives of 81%. In level 2 (Learning), all the differences between the retrospective pre and posttest were statistically significant (p < 0.01), and achievement of learning was in average 82.9%. In level 3 (Behavior), 100% felt they would apply what was learnt and 17 PD (57%) sent projects. Conclusions: This model of faculty development was highly accepted by PD and had a positive evaluation based in high satisfaction, the improvement in pre/posttest assessment, the achievement of learning objectives and the development of projects.

Background: The medical school of the Pontificia Universidad Católica de Chile offers a Diploma on Medical Education (DME) for its faculty since 2000. However its impact had never been evaluated. Aim: To determine the perception of the graduates of the impact of DME, using the Kirkpatrick model for evaluation of educational outcomes. Material and Methods: A questionnaire containing closed and pre-post retrospective questions that represented Kirkpatrick's four levels of evaluation, was sent to all the graduates in 2009. Results: Eighty two of 91 graduates returned the questionnaire. Ninety one percent had a high level of satisfaction at Kirkpatrick Level 1 (Reaction), and perceived an average of 81.8% completed objectives. Most respondents reported modification of attitudes and perceptions about teaching, at Kirkpatrick Level 2 (Learning). All the differences between the pre and posttest retrospective questionnaire were statistically significant. More than 98% of responded stated that they improved their role as teacher using the skills learned during DME, according to Kirkpatrick Level 3 (Behavior). According to Kirkpatrick Level 4 (Outcomes), 66% stated that the DME contributed to appreciate the value of teaching at an institutional level. Conclusions: According to the perception of the respondents, the DME has had a positive impact at all the levels described in the Kirkpatrick model.

OBJETIVO: Descrever e analisar três ferramentas usadas no sistema de avaliação aplicado ao internato em pediatria por um período de 7 anos na Faculdade de Medicina, Pontificia Universidad Católica de Chile, Santiago, Chile. MÉTODOS: Pesquisa observacional retrospectiva projetada para as modalidades de avaliação usadas de 2001 a 2007 que foram implementadas no internato em pediatria. As ferramentas foram as seguintes: exame clínico objetivo estruturado (objective structured clinical examination, OSCE), exame escrito e diretrizes de observação de prática clínica diária (DOPCD). Os métodos de avaliação foram aplicados ao internato em pediatria do sexto ano, com um total de 697 alunos. A análise estatística incluiu uma avaliação descritiva, com correlação e regressões linear simples e múltipla (ANOVA), teste de Bonferroni e coeficiente alfa de Cronbach. O nível de significância foi de 5%. RESULTADOS: Escores de sucesso com a OSCE foram atingidos em 75,7±8%, com melhor média entre o sexo feminino (p < 0,001). Os escores de OSCE melhoraram após o terceiro ano de implementação. O coeficiente alfa de Cronbach foi de 0,11-0,78. O exame escrito teve escore médio de 79,8±10%, e não houve diferenças quanto a gênero. O escore médio de DOPCD 97,1±3%, com melhores resultados entre as mulheres (p < 0,005). A correlação entre os três métodos de avaliação mostrou uma relação positiva moderada, exceto no ano de 2007, quando a correlação foi maior (p < 0,001). CONCLUSÕES: Análise do sistema de avaliação da aprendizagem foi realizada usando OSCE, exame escrito e DOPCD, que são complementares entre si, gerando bons resultados.

OBJECTIVE: To describe and analyze three tools used in the assessment system applied to the pediatric internship over a 7-year period at the School of Medicine, Pontificia Universidad Católica de Chile, Santiago, Chile. METHODS: Retrospective observational research design for the assessment modalities implemented in the pediatric internship from 2001 through 2007. The tools were as follows: objective structured clinical examination (OSCE), written examination and daily clinical practice observation guidelines (DCPOG). The assessment methods were applied to the sixth-year pediatric internship with a total of 697 students. Statistical analysis included a descriptive assessment, with correlation and simple linear and multiple regressions (ANOVA), Bonferroni test and Cronbach's alpha coefficient. Significance level was set at p < 0.05. RESULTS: OSCE success scores were reached in 75.7±8%, with a better mean among females (p < 0.001). OSCE scores improved after the third year of implementation. Cronbach's alpha coefficient was 0.11-0.78. Written examination had a mean score of 79.8±10% and there were no sex differences. Mean DCPOG score was 97.1±3% and the results were better among females (p < 0.005). Correlation between the three assessment methods showed a moderate positive relationship except in the year of 2007, where the correlation was higher (p < 0.001). CONCLUSIONS: Analysis of the learning assessment system was performed using OSCE, written examination and DCPOG, which are complementary to each other, and yielded good results.

Effective clinical teaching is an imperative of medical education. Clinical teachers and faculty development initiatives as well as Medical Schools, need to focus their efforts to pursue common outcomes: effective learning in students, future competent physicians and healthy patients. Excellence in quality of teaching needs scholars in education. To achieve this objective, institutions must recruit a core of medical faculty according to its mission, define the attributes and teaching competences, implement faculty development programs, and finally, support academic vitality. This article describes the three main issues of medical teaching: faculty, faculty development and its organization.

Esta investigación tuvo como propósito principal caracterizar los marcos de referencia de los maestros que favorecen la comprensión de las matemáticas en estudiantes de primaria en 10 colegios de Bogotá. Se utilizó una investigación de tipo cualitativo, en la cual se identificaron estudiantes que evidenciaban un desempeño académico en el área de matemáticas por encima del promedio, luego se recogió información a través de la observación en el aula y de la entrevista semiestructurada a los maestros. Se utilizó el análisis de contenido de tipo categorial y las matrices de cotejación. Como resultado se evidenció el papel predominante de la afectividad, los contextos inmediatos y la historia de vida de los estudiantes en los marcos de referencia de los maestros.

The aim of this research was to characterize the reference framework of teachers that favour mathematical comprehension at the elementary level in ten schools in Bogotá. A qualitative research was used in which the students who showed performance above average were identified. The information was then gathered through direct classroom observation and semi- structured interview of the instructors. A categories analysis as a type of content analysis was also used. As a result, the predominant roll of affectivity was found out together with immediate contexts, and the life history of the students in the reference framework of the teachers.

Background: The Objective Structured Clinical Examination (OSCE) has become a respected and widely used tool for the assessment of clinical competence in medical education. Aim: To describe the first experience of an OSCE as a summative assessment in undergraduate Pediatric Internship, in two universities. Material and Methods: The OSCE was structured by a committee of faculty members of the 5 campi of University of Chile and I campus of the Catholic University. A 21 station OSCE was administered simultaneously to 124 Pediatric Interns (University of Chile =104, Catholic University=20), in 3 centers. A total of 50 faculty members participated in the examination. The OSCE consisted of 20 clinical problems, including videotape recordings, photographs, x-rays and laboratory exams, phantoms and 7 simulated standardized parents. Results: The average total OSCE score was 67.3% (range: 84.5%-43.5%). The maximum theoretic score was achieved in 19 stations. A significant correlation between station and total score, was found for 18 of the 20 clinical problems. Conclusions: The experience of using OSCE has been a success. The OSCE was an adequate procedure to assess a large number of interns simultaneously and it allowed us to measure the main objectives in all domains and a wide range of clinical competence of Pediatric Internship Programs (Rev Méd Chile 2002; 130: 817-824).

Objectives: To evaluate the intestinal parasitic infection frequency in coproparasitological samples in infants. To compare clinical-epidemiological variables among infants with/without parasitic infection. Subjects and Methods: a descriptive retrospective study was performed in 3,127 coproparasitological samples processed at Pontificia Universidad Católica de Chile (1994-1998) determining frequency and parasitic species. Results: 167 (5.3%) showed parasitic infection, only protozoan, mainly G. lamblia. The most frequent reason for requesting the coproparasitological exam in infants with parasitic infection was diarrhea. Also 84.1% of the infected children were well-nourished and 4.5% with malnutrition. The most frequent reason for requesting the exam in infants without intestinal parasitic infection was failure to thrive and malnutrition. In this group, 68.9% were well-nourished and 24.4% with malnutrition. Conclusions: Presence of enteric protozoan was found in the coproparasitological exams performed in infants (absence of helminths highlights as an important finding). The presence of pathogens protozoan was mainly associated with diarrhea and it was not a major factor related to malnutrition and failure to thrive

Objetivos: Determinar la frecuencia y tipo de enteroparásitos en exámenes coproparasitológicos tomados a lactantes. Comparar en un subgrupo de lactantes con y sin enteroparásitos, variables clínico-epidemiológicas. Pacientes y métodos: estudio retrospectivo descriptivo realizado en el total de 3 127 exámenes coproparasitológicos procesados en la Pontificia Universidad Católica de Chile (1994-1998), determinándose la frecuencia y especies parasitarias. Comparación de resultados entre grupos de lactantes con exámenes coproparasitológicos positivos y negativos respecto a motivo de solicitud del examen y diagnóstico nutricional. Resultados: Ciento sesenta y siete (5,3%) de los exámenes fueron positivos, encontrándose solo protozoos, principalmente G. lamblia. En lactantes con examen coproparasitológico positivo el motivo de solicitud más frecuente fue síndrome diarreico agudo y disentérico, de los cuales el 84,1% eran eutróficos y 4,5% desnutridos. En lactantes con examen coproparasitológico negativo la solicitud de examen se debió a mal incremento ponderal y desnutrición, encontrándose el 68,9% eutróficos y 24,4% desnutridos. Conclusiones: Se encontró presencia de enteroparásitos en los exámenes coproparasitológicos realizados a lactantes (en estos, destaca la ausencia de helmintos). La presencia de protozoos patógenos se asoció con deposiciones diarreicas y no se observó asociación con desnutrición o mal incremento ponderal
