Introducción: El Bisfenol A (BPA) es un disruptor endócrino (DE) posiblemente vinculado a eventos adversos reproductivos y del desarrollo neurológico que se utiliza como aditivo en envases plásticos de alimentos y bebidas. En la población argentina no existen datos sobre niveles de BPA en orina. El objetivo del estudio fue medir la presencia de BPA en orina de embarazadas.Métodos: Estudio transversal. Detección de BPA en orina de embarazadas atendidas en el Hospital Italiano de Buenos Aires en el año 2013. La técnica utilizada fue cromatografía gaseosa asociada a espectrometría de masa con un límite de cuantificación de 2 ng/ml y de detección de 0,8 ng/ml. Se describe la proporción de mujeres con exposición al BPA con su intervalo de confianza del 95% (IC95%).Resultados: se analizaron 149 muestras de orina de embarazadas de edad promedio 32 años (Desvío Standard 5,3), el 81% (IC95% 73,9-86,9) trabaja y el 83,7% (IC95% 76,7-89,1) posee nivel universitario y/o posgrado.El 66,4% (IC95% 58,2-74,0) de las muestras urinarias presentaron BPA cuantificable, siendo la mediana de BPA de 4,3 ng / mg creatinina (Rango Intercuartilo 3,2-6,7).Conclusiones: Este estudio muestra que la exposición a BPA durante el proceso de formación embrionaria en un sector de la población de Argentina, es generalizada. En Argentina solo está regulado el uso de este DE en mamaderas.

Research is important during university education. The objective was to describe the teaching of an exercise in clinical research and its perception by students. Medical students conducted a research work in groups coordinated by a tutor. We evaluated the importance the students gave to research learning and we assessed the satisfaction of having participated in the activity in a scale from 1 to 10. Eighty-one students developed 14 research exercises, 44.4% reported having received training in research methodology before and 11.1% had participated in some research study. They assigned a score of 8 out of 10 to the importance of research and 9 out of 10 to the satisfaction of having participated in the activity. The aspects of the exercise in clinical research perceived as positive were that it favoured teamwork and helped students to understand how to conduct a research study.

El objetivo de este trabajo fue describir la enseñanza de un ejercicio de investigación clínica y su percepción por parte de los estudiantes. Estudiantes de Medicina realizaron un trabajo grupal coordinados por un tutor. Se evaluó la importancia que les daban los alumnos al aprendizaje de la investigación y la satisfacción de haber participado en una escala de 1 a 10. Ochenta y un estudiantes desarrollaron 14 ejercicios de investigación. El 44,4% refirió haber recibido formación en metodología de la investigación y el 11,1% había participado de algún estudio de investigación. Se le asignó un puntaje de 8 a la importancia de investigar y 9 a la satisfacción de haber participado de la actividad. Los aspectos del ejercicio de investigación clínica percibidos como positivos fueron que favoreció el trabajo en equipo y que ayudó a comprender cómo se realizaba un estudio de investigación.

OBJETIVO: Avaliar a qualidade de vida psicossocial em filhos de pais separados em idade escolar. METODOS: Conduziu-se um estudo transversal no ambulatorio pediatrico de um hospital comunitario. Foram incluidas criancas de 5 a 12 anos de idade, de familias intactas e de familias separadas. A qualidade de vida das criancas foi avaliada atraves de relatorios maternos, utilizando-se o Child Health Questionnaire - Parent Form 50. Um modelo de regressao linear multipla foi construido incluindo variaveis clinicamente relevantes significativas para a analise univariada (coeficiente beta e IC de 95%). RESULTADOS: Trezentas e trinta familias foram convidadas a participar e 313 preencheram o questionario. A analise univariada demonstrou que a qualidade de vida estava significativamente associada a separacao parental, sexo da crianca, tempo passado com o pai, padrao de vida e nivel de instrucao materno. Em um modelo de regressao linear multipla, os escores de qualidade de vida se mostraram mais baixos em meninos -4,5 (-6,8 a -2,3) e mais altos para tempo passado com o pai 0,09 (0,01 a 0,2). Em familias separadas, a regressao demonstrou que os escores de qualidade de vida foram maiores quando a separacao dos pais ocorrera em acordo mutuo 6,1 (2,7 a 9,4), quando a mae possuia nivel universitario 5,9 (1,7 a 10,1) e para cada ano passado desde a separacao 0,6 (0,2 a 1,1), enquanto os escores foram menores em meninos -5,4 (-9,5 a -1,3) e para cada incremento de um ano da idade materna -0,4 (-0,7 a -0,05). CONCLUSAO: A qualidade de vida psicossocial das criancas foi afetada pela separacao. O Child Health Questionnaire pode ser util para detectar um declinio na qualidade de vida psicossocial.

In the last year there was happened a series of adolescent deaths in the province of Salta that might be related to a dangerous game known as "the choking game". It has been practiced over many years in different countries around the world and consists of provoking brain hypoxia for some seconds by different techniques to obtain an instant of ecstasy and pleasure. We consider relevant that health providers know about this practice and so be able to recognize through signs and symptoms when an adolescent might be playing this game.

The greeting is the first form of verbal and nonverbal communication and is a valuable tool to support the physician-patient relationship.Assess parents and children preferences on how they want pediatricians greet and address them.Cross-sectional study. The population was persons accompanying patients (parents or guardians) between 1 month and 19 years old and patients older than 5 years old. A survey questionnaire was completed after the medical visit.A total of 419 surveys from patients' companions and 249 from pediatric patients were analyzed; 68% of the companions preferred the doctor addressed them by the first name, 67% liked to be greeted with a kiss on the cheek and 90% liked to be treated informally. Preferring to be greeted with a kiss on the cheek was associated in multivariate analysis with the companion was the mother, age younger than 39 years and longer time in knowing the pediatrician; 60% of the patients preferred to be addressed by their first name.In the outpatient setting patients companions and patients themselves prefer to be addressed by their name informally and be greeted with a kiss on the cheek.

Consultation to complementary and alternative medicines (CAM) in the pediatric population is becoming more frequent.To assess the prevalence of the consultations, the communication with their doctors and the characteristics of patients and families who consult CAM.A transversal study was done. All healthy children age 4 to 17 who attended with a responsible adult to the emergency unit were included. The sample was taken in a consecutive non randomized way.Two hundred and eighty carers of the children were invited to participate in the study and 246 completed the survey. All of the patients had their basic needs satisfied and a health insurance. The medium age of the children was 9.2 and the one of the carers 39.6 years. In 72% of the visits the carer was the mother and in 24% the father. Some CAM was known by 84.5% and 13% had consulted in some opportunity. Homeopathy was the most known (76%) and consulted (8.8%). 96.7% of the children that used a CAM continued their clinical follow-up with their pediatrician but 42% of the carers did not tell this to the pediatrician. The carers of the patients who consulted CAM said that more time was given in the visit (42%), the symptoms for which their consulted got better (78.5%) and they found an answer to their child's health problem (87%).From surveyed people, 84.5% knew about CAM and 13% of the children had consulted at some moment. Homeopathy was the most known (76%) and the most consulted (8.8%). Almost all of the children that consulted a CAM continued their clinical follow-up with their pediatrician but 42% didn't tell them about their consultation.
