RESUMEN
Abstract The clinical and biochemical findings in a cohort of 51 patients with urea cycle disorders followed at the Hospital Garrahan, Buenos Aires, Argentina were analyzed at the time of diagnosis (3 female patients were excluded). Of this cohort, 13/48 patients had early-onset (EO), 23/48 had late-onset (LO), and 12/48 had a different presentation because they had a family risk background (FRB) and had been diagnosed since they were born. The most frequent deficiency disorder was OTCD (65%). The initial ammonium value was evaluated, being higher in the EO group, with a statistically significant difference when compared with LO and FRB. 15/48 patients fell into a coma at the time of diagnosis, mean ammonia was 829.54 μmol / L, and 33/48 did not fell into a coma, the mean ammonium was of 159.3 μmol / L (p = 0.001). 15 patients died: 62% EO, 22% LO (p=0.0216), 17% FRB. A molecular study was performed on 35 patients. Patients with EO presentation suffer the most severe forms and still have high morbimortality. On the other hand, LO forms are forms of less severity that are finally diagnosed as a result of one or more acute episodes.
RESUMEN
Resumo Este artigo apresenta uma investigação acerca da influência que as variáveis de background familiar (escolaridade do pai, escolaridade da mãe e renda familiar) exercem sobre o desempenho de um estudante, candidato às vagas dos processos de seleção em uma instituição de Ensino Técnico Federal brasileira. A pesquisa consistiu em analisar a influência do background familiar, como determinante de desempenho do aluno, no acesso ao Ensino Técnico Profissional brasileiro. Para conduzir essa investigação foram utilizados dados secundários, totalizando 19.226 observações. Buscando alcançar o objetivo proposto, formulou-se um modelo conceitual composto por 3 hipóteses. Os resultados são apresentados em 3 etapas: etapa I - separação dos campi em clusters; etapa II - análise das regressões múltiplas; e etapa III - análise das regressões logísticas. As hipóteses 1 e 2 foram confirmadas e a Hipótese 3, refutada. Os resultados apresentaram um efeito positivo das variáveis renda familiar e escolaridade do pai, mas sem significância estatística para a variável escolaridade mãe.
Resumen Este trabajo presenta una investigación acerca de la influencia que las variables de antecedentes familiares (escolaridad del padre, escolaridad de la madre y renta familiar) ejercen sobre el desempeño de un estudiante candidato a las vacantes de los procesos de selección en una institución de Enseñanza Técnica Federal brasileña. El estudio consiste en analizar la influencia del trasfondo familiar como determinante de desempeño del alumno en el acceso a la Enseñanza Técnica Profesional brasileña. Para conducir esta investigación, se utilizaron datos secundarios totalizando 19.226 observaciones. Buscando alcanzar el objetivo propuesto, se formuló un modelo conceptual compuesto por tres hipótesis. Los resultados se presentaron en tres etapas: etapa I - separación de los campi en clusters; etapa II - análisis de las regresiones múltiples y etapa III - análisis de las regresiones logísticas. Se han confirmado las hipótesis 1 y 2 y, H3, refutada. Los resultados mostraron un efecto positivo de las variables renta familiar y escolaridad del padre, pero sin significancia estadística para la variable escolaridad materna.
ABSTRACT This work investigates the influence of family background variables (father's schooling, mother's schooling, and family income) on the result of a student's application to access a Brazilian institution of technical and vocational education. The research used secondary data carried out 19,226 observations, and formulated a conceptual model with three hypotheses. The results were presented in three stages: I - separation of campuses into clusters; II - analysis of multiple regressions; and, III - analysis of logistic regressions. One of the hypotheses was rejected and two were confirmed, indicating that there is a positive effect of the variables family income and father's schooling, but no statistical significance for the variable mother's schooling.

Se presentan resultados de una investigación que indaga el consumo de sustancias psicoactivas en una población clínica de niños entre 8 y 12 años que recibe asistencia psicológica en un servicio comunitario, dependiente de la Segunda Cátedra de Psicoanálisis: Escuela Inglesa de la Facultad de Psicología de la Universidad de Buenos Aires, Argentina. Asimismo se indaga el consumo de sustancias psicoactivas en los adultos responsables que acompañan a los niños a la consulta. Las muestras están conformadas por 55 niños (17 niñas y 38 niños) y 55 adultos responsables (47 mujeres y 8 varones). Se administró el cuestionario CORIN (Conductas de riesgo en niños), un cuestionario para padres o adultos responsables y un protocolo de datos sociodemográficos. Resultados: se registró la presencia del consumo ocasional de alcohol en el 33% de los niños y una alta proporción de prevalencia de consumo de alcohol en la vida, año y mes por parte de los adultos. A su vez, entre los adultos se registraron situaciones de consumo abusivo. Se infiere que el consumo ocasional de alcohol por parte de niños se asocia a las características de su contexto familiar y a los hábitos de consumo de sus adultos responsables.
The paper presents the results of an investigation Project UBACYT (Programming 2010/12) "Consumption of psychoactive substances and expectancies towards alcohol in school children between 8 and 12 years old". The paper studies a clinical sample that receives psychological assistance in a Child Clinical Psychology Unit that depends on Segunda Cátedra de Psicoanálisis: Escuela Inglesa, Facultad de Psicología, Universidad de Buenos Aires, Argentina. It investigates the consumption of these substances in children and their responsible adults. The samples are composed of 55 children (17 girls and 38 boys) and 55 responsible adults (47 women and 8 men). The CORIN (Children Risk Behavior) was administrated to the children, it evaluates risk situations regarding to the use of psychoactive substances in school children; a questionnaire that inquires consumption habits was administrated to parents or responsible adults of these children. Also, a protocol of sociodemographic information was used in order to gather and systematize the information of the medical history. Results and conclusions: the presence of occasional alcohol consumption in the 33% of the children sample was recorded. The existence of alcohol consumption in previous ages than the ones studied by governmental agencies. It must be mentioned that the children have consumed alcohol in festive situations and in company of their responsible adults. Regarding to the responsible adults of these children, important proportions of lifetime, year and month prevalence of occasional alcohol and tobacco consumption were recorded; also the abusive consumption of these substances. The registered proportions of the consumption of illegal substances are much lower. The study shows an increase in the occasional consumption of alcohol in children when the responsible adult made an abusive use of alcohol and tobacco during the last year and in less extent when the adult used more than one illegal substance (cocaine and marihuana). The consumption of alcohol in children increased significantly when the responsible adults had made abusive use of alcohol in the last month. It is inferred that the occasional consumption of alcohol in children of the age range studied, is associated with the characteristics of their family background and the consumption habits of the responsible adults.
