estudi descriptiu dels pacients majors de 60 anys amb diagnòstic de trombocitopènia immune primària en un centre. S'han revisat característiques bàsiques en el moment de l'inici de la malaltia, així com les diferents línies de tractament, resposta, evolució i complicacions sorgides en aquest grup d'edat, en què la literatura publicada sobre aquest tema és menor que en els pacients joves.

Determinación de la edad y crecimiento de la Sardina Sardinops sagax sagax (J)

Determinación de la sardina Sardinops sagax sagax (J.), del área del Callao, mediante métodos de lecturas y mediciones de las marcas de los anillos de crecimiento de 243 otolitos. Los métodos empleados se adjuntan a la especie estudiada con facilidad y los resultados se consideran satisfactorios. En el cálculo de los parámetros de crecimiento se aplica la ecuación de Von Bertalanffy, con cuyas expresiones se calcularon las tallas y pesos teóricos por edades. Al relacionar la edad con las tallas de captura, para los niños 1973 y 1974, se determinó la predominancia del grupo de edad 4 años en 1973; posteriormente, en 1974 se experimentaron cambios en la estructura poblacional presentándose una predominancia del grupo de edad 2 conjuntamente con el de 3 años de edad. La edad relacionada al peso deja ver que existe una correspondencia entre ambos, muy similar en machos y hembras hasta la edad de 3 años; esto hace suponer la igualdad de condiciones nutricionales. A partir de esa edad, las hembras incrementan su peso en menor proporción, lo que debe depender del mayor desgastes en los desoves, muy notorio en individuos mayores. La tasa máxima de crecimiento es alcanzada a los 4 años en los machos y a los 3 años en las hembras, con un promedio de 1.90 y 1.17, respectivamente. La distribución por edades guarda relación con los grupos de tallas correspondientes a las capturas, a pesar de que la cantidad de observaciones no cubre el rango de distribución real por tallas.

En torno a los efectos de la edad en el aprendizaje escolar de una lengua extrangera

The purpose of this article is to treat a currently much debated issue, the effects of age on second language learning. To do so, we contrast data collected by our research team from over one thousand seven hundred young and adult learners with four popular beliefs or generalizations, which, while deeply rooted in this society, are not always corroborated by our data.Two of these generalizations about Second Language Acquisition (languages spoken in the social context) seem to be widely accepted: a) older children, adolescents and adults are quicker and more efficient at the first stages of learning than are younger learners; b) in a natural context children with an early start are more liable to attain higher levels of proficiency. However, in the context of Foreign Language Acquisition, the context in which we collect the data, this second generalization is difficult to verify due to the low number of instructional hours (a maximum of some 800 hours) and the lower levels of language exposure time provided. The design of our research project has allowed us to study differences observed with respect to the age of onset (ranging from 2 to 18+), but in this article we focus on students who began English instruction at the age of 8 (LOGSE Educational System) and those who began at the age of 11 (EGB). We have collected data from both groups after a period of 200 (Time 1) and 416 instructional hours (Time 2), and we are currently collecting data after a period of 726 instructional hours (Time 3). We have designed and administered a variety of tests: tests on English production and reception, both oral and written, and within both academic and communicative oriented approaches, on the learners' L1 (Spanish and Catalan), as well as a questionnaire eliciting personal and sociolinguistic information. The questions we address and the relevant empirical evidence are as follows: 1. "For young children, learning languages is a game. They enjoy it more than adults."Our data demonstrate that the situation is not quite so. Firstly, both at the levels of Primary and Secondary education (ranging from 70.5% in 11-year-olds to 89% in 14-year-olds) students have a positive attitude towards learning English. Secondly, there is a difference between the two groups with respect to the factors they cite as responsible for their motivation to learn English: the younger students cite intrinsic factors, such as the games they play, the methodology used and the teacher, whereas the older students cite extrinsic factors, such as the role of their knowledge of English in the achievement of their future professional goals. 2 ."Young children have more resources to learn languages." Here our data suggest just the opposite. The ability to employ learning strategies (actions or steps used) increases with age. Older learners' strategies are more varied and cognitively more complex. In contrast, younger learners depend more on their interlocutor and external resources and therefore have a lower level of autonomy in their learning. 3. "Young children don't talk much but understand a lot"This third generalization does seem to be confirmed, at least to a certain extent, by our data in relation to the analysis of differences due to the age factor and productive use of the target language. As seen above, the comparably slower progress of the younger learners is confirmed. Our analysis of interpersonal receptive abilities demonstrates as well the advantage of the older learners. Nevertheless, with respect to passive receptive activities (for example, simple recognition of words or sentences) no great differences are observed. Statistical analyses suggest that in this test, in contrast to the others analyzed, the dominance of the subjects' L1s (reflecting a cognitive capacity that grows with age) has no significant influence on the learning process. 4. "The sooner they begin, the better their results will be in written language"This is not either completely confirmed in our research. First of all, we perceive that certain compensatory strategies disappear only with age, but not with the number of instructional hours. Secondly, given an identical number of instructional hours, the older subjects obtain better results. With respect to our analysis of data from subjects of the same age (12 years old) but with a different number of instructional hours (200 and 416 respectively, as they began at the ages of 11 and 8), we observe that those who began earlier excel only in the area of lexical fluency. In conclusion, the superior rate of older learners appears to be due to their higher level of cognitive development, a factor which allows them to benefit more from formal or explicit instruction in the school context. Younger learners, however, do not benefit from the quantity and quality of linguistic exposure typical of a natural acquisition context in which they would be allowed to make use of implicit learning abilities. It seems clear, then, that the initiative in this country to begin foreign language instruction earlier will have positive effects only if it occurs in combination with either higher levels of exposure time to the foreign language, or, alternatively, with its use as the language of instruction in other areas of the curriculum.

Morbilidad de la extracción de los terceros molares en pacientes entre los 12 y 18 años de edad

Objetivo: El propósito de este estudio fue analizar la incidencia de complicaciones después de la extracción quirúrgica de los terceros molares en pacientes de 12 a 18 años de edad. Pacientes y método: Se realizó un estudio retrospectivo de 390 extracciones quirúgicas de terceros molares superiores e inferiores en 173 pacientes en edades comprendidas entre los 12 y 18 años de edad, intervenidos bajo anestesia locorregional en el año 2000 en el Máster de Cirugía Bucal e Implantología Bucofacial de la Universidad de Barcelona. Los pacientes fueron divididos en tres grupos (A: 12-14 años, B:15-16 años, C: 17-18 años). Se registró la edad y el sexo del paciente, el motivo de la extracción, el grado de desarrollo dentario, la posición, la angulación y la inclusión del tercer molar. Finalmente se valoró la asociación entre dichas variables y la aparición de complicaciones postoperatorias. Resultados: La mayoría de los pacientes intervenidos fueron del sexo femenino (66,9%), y el grupo de edad en la que se realizó el mayor número de extracciones (62,8%) fue en el grupo C (17-18 años). El principal motivo de extracción fue la indicación por parte del ortodoncista (40,5%), seguido por la indicación profiláctica (39,5%). La presencia de clínica fue el motivo de extracción en un 20% de los casos. Se observó una incidencia del 15,6% de complicaciones postoperatorias tras la extracción de 390 terceros molares. En el grupo A el riesgo de complicaciones fue de 17,4%, en el grupo B de 19% y en el grupo C de 13,7%. Todas las complicaciones fueron reversibles y de corta duración como el dolor y la inflamación persistente, la infección, el trismo y la equimosis. Se presentó un caso de parestesia del nervio dentario inferior y un caso de parestesia del nervio lingual que remitieron a los 2 meses y al mes respectivamente. Conclusiones: este estudio demuestra que no hay diferencias significativas en las complicaciones observadas entre los tres grupos de edad, y por lo general, éstas son leves y reversibles. Se observó una mayor tendencia de complicaciones en las mujeres y el porcentaje de complicaciones aumenta cuanto menor es el espacio disponible para la erupción

Diagnóstico de apendicitis aguda en la edad pedíatrica en la Fundación Cardio Infantil : utilidad de la ultrasonografía

Los niños que presentan dolor abdominal agudo representan una de las principales demandas de atención en los servicios de Urgencias Pediátricas, convirtiéndose en un reto para quien realiza la valoración inicial la decisión de que paciente amerita realizar estudios adicionales, para descartar una patología quirúrgica. Considerando que la apendicitis es la primera emergencia quirúrgica en niños, y que sus complicaciones son un problema frecuente, es imprescindible que el clínico conozca cual es la utilidad y beneficio que le brindan las herramientas diagnósticas disponibles para realizar un diagnóstico más certero. Objetivo: Describir el manejo de los pacientes menores de 18 años con sospecha de apendicitis en la FCI y determinar la sensibilidad y especificidad de la ecografía en esta población. Métodos: Estudio de Prueba Diagnóstica. Revisión expedita de los niños valorados en la FCI con sospecha clínica de apendicitis aguda durante un periodo de 4 meses. Se tomaron datos de hallazgos ecográficos para apendicitis (positivos, negativos o indeterminados) y del desenlace de tener o no apendicitis. Posteriormente se realizó una inferencia mediante una tabla de contingencia, teniendo en cuenta intervalos de confianza para determinar la sensibilidad, especificidad, VPP, VPN y exactitud de la prueba basados en el diagnóstico final. Resultados: En 52% de pacientes que consultaron por dolor abdominal se sospecho patología quirúrgica, grupo en el que se utilizó la ecografía abdominal como herramienta diagnóstica para descartar apendicitis encontrando: sensibilidad: 63%(IC 95%, 48.6-75.5), especificidad: 82,7%(IC 95%, 76- 87.8) y exactitud: 78,2%(IC 95%, 72-83,4). La prevalencia de la enfermedad fue 22,8%, con probabilidad postprueba positiva de 88.3%(IC 95%, 82,1-92.6). Conclusiones: Los resultados de este estudio evidencian un menor rendimiento de la ecografía como prueba diagnóstica para apendicitis en pediatría en nuestro medio comparado al descrito en la literatura. Dicha discordancia probablemente se encuentra determinada por los sesgos propios de un estudio histórico como este, en el que básicamente la falta de uniformidad en el registro de datos en la historia clínica por los observadores (clínicos y radiólogos), así como las limitaciones para determinar el seguimiento de todos los pacientes que no fueron operados, pueden alterar la capacidad operativa real de la prueba. De ahí la importancia de realizar a futuro un estudio concurrente.

Análisis del reclutamiento forzado a menores de edad en Colombia

Los menores de edad en Colombia han sido el blanco de los grupos como el ELN y las FARC quienes los reclutan con el fin de incrementar su esquema de lucha, esto gracias a que los niños son fácilmente amoldable a nuevas estructuras emocionales, sin contar que muchos de estos pequeños atraviesan por difíciles situaciones en sus hogares.

Características de adaptación de los diabéticos de edad escolar.

Hacer un análisis descriptivo de las variables de ajuste y adaptación personal, social, escolar y familiar de los diabéticos con edad escolar en Canarias. También se intenta detectar cuáles son los principales estilos educadores de los padres de los niños diabéticos. Investigación 1. Participaron 160 sujetos, 82 niñas y 78 niños, de los cuales 80 eran diabéticos. Los 80 no diabéticos formaban el grupo control. Investigación 2. 160 diabéticos y no diabéticos; participaron también los padres y madres de los niños diabéticos junto a 23 médicos expertos en diabetes en Canarias. Investigación 1. Estudio correlacional en cuanto que investiga la relación existente entre las variables personal, escolar, social y familiar. Es también un estudio predictivo porque intenta hallar variables que ayuden a predecir un perfil de niño-a o adolescente diabético y/o no diabético y el estilo educador de los padres. Investigación 2. Se planificó un estudio correlacional y descriptivo. Correlacional: al investigar la relación existente entre una serie de variables de personal, escolar, social y familiar. Predictivo: porque intenta hallar variables que ayuden a predecir un perfil del niño diabético y futuro estilo educador de los padres. Investigación 1. Test autoevaluativo multifactorial de adaptación (TAMAI); entrevista semiestructurada de adaptación (ESDA). Investigación 2. El TAMAI, entrevista semiestructurada de diagnóstico de la adaptación y cuestionario situacional. 1. Puede observarse que los niños diabéticos no se perciben con más problemas de inadaptación personal, social, escolar y familiar que los niños no diabéticos en los tres niveles del TAMAI. A nivel personal tienen menos problemas de sueño. 2. Por lo que respecta a las diferencias por niveles evolutivos vemos que existen características diferenciales entre los diabéticos del nivel II, los del nivel I y los del nivel III, al igual que entre los no diabéticos del nivel II, los del nivel I y nivel III. Los del nivel II no tienen problemas de sueño, comida, están más satisfechos con la edad que tienen, más valientes y con menos miedos y con mayor proimagen. Con mayor dificultad en su relación social por agresividad y perciben discrepancias educativas entre sus padres. Los del nivel I con menos interés por el aprendizaje, les afectan menos los aspectos somáticos, igual que los del nivel II. Para ambos, no tienen sentimientos de inferioridad, no se autocastigan, tienen buen autoconcepto y más contradicciones. Además no perciben a sus padres como permisivos ni con marginación afectiva. Los del nivel III tienen más problemas y preocupaciones, menos satisfechos de ellos mismos, menor diferencia de temporalización de su edad, más trabajadores y organizados en la escuela. Menos problemas con la actividad física y sueño, pero insatisfechos con la familia. Los del nivel III y II se ven más adaptados escolarmente, más motivados y disciplinados. Los del nivel III y I tienen más dificultades con la atención pero presentan buenas relaciones sociales. Como síntesis final de los resultados extraídos de la investigación, se podría señalar que, efectivamente, el grupo diabéticos presentan más problemas físicos y pasivos que el grupo no diabético, que se muestra más activo y con menos cansancio físico.

Situación de salud y nutrición en la población menor de 18 años de Providencia y Santa Catalina

Las enfermedades transmisibles de notificación obligatoria continúan teniendo una prevalencia significativa en la comunidad. Con los resultados del estudio hecho en torno a esta problemática se pretende evaluar la situación de salud y nutrición de la población infantil de las Islas de Providencia y Santa Catalina. Metodología: durante un período de seis días se realizó una brigada de salud. Se valoraron médicamente los niños entre cero y 18 años de edad. Se clasificaron los pacientes de acuerdo con las patologías más frecuentes, con los grupos etéreos, con el estado nutricional y con la afiliación a seguridad social. Resultados: se valoraron 366 pacientes, 164 niñas y 202 niños. La infección respiratoria aguda fue la tercera causa de consulta de la población menor de cuatro años de edad. La condición de malnutrición predominante fue la de sobrepeso. Más de la mitad de la población infantil pertenece al régimen subsidiado. El consumo de frutas y verduras es deficiente. Conclusión: las estrategias en salud en la población de Providencia deben estar encaminadas hacia la disminución de la prevalencia de sobrepeso y de enfermedades transmisibles dentro de la población infantil mediante programas de atención básica.

Factores asociados a deficiencia de zinc en niños colombianos entre 1 y 4 años de edad

Introducción: Las deficiencias de micronutrientes continúan siendo un problema de salud pública en la población infantil, dentro de las ellas se ha encontrado a la deficiencia de zinc causa importante de morbi-mortalidad en los países en desarrollo, la nutrición adecuada de zinc es esencial para un crecimiento adecuado, inmunocompetencia y desarrollo neuroconductual; se dispone de información insuficiente sobre el estado de zinc en la población preescolar lo cual dificulta la expansión de las intervenciones para el control de su deficiencia. Colombia presenta una deficiencia de este micronutriente, considerándose a nivel mundial como un problema de salud pública moderado a severo. Una evaluación sobre la prevalencia y factores determinantes asociados puede proporcionar datos sobre el riesgo de deficiencia de zinc en una población, considerando factores demográficos, sociales y nutricionales que podrían predisponer a la población preescolar colombiana a sufrir este déficit. Metodología: Estudio observacional de corte transversal que incluyó 4275 niños entre 1 y 4 años, utilizando datos de la Encuesta Nacional de Situación Nutricional (ENSIN-2010). Se realizaron análisis bivariados y multivariados para determinar factores asociados positiva y negativamente con deficiencia de zinc. Resultados: El 49,1% de los niños encuestados cursaban con deficiencia de zinc. Los factores de riesgo asociados a deficiencia de zinc encontrados fueron menor edad, peso y talla bajos, vivir en región Atlántica, región Central, Territorios Nacionales, vivienda en área de población dispersa, pertenencia a etnia afrocolombiana, pertenencia a etnia indígena, estar afiliado a régimen subsidiado, no estar afiliado a ningún régimen de salud, madre sin educación, no asistencia a programa de alimentación dirigido y el grado severo de inseguridad Conclusiones: El déficit de zinc en los niños entre 1 y 4 años de edad es multifactorial, siendo un reflejo probable de la situación de inequidad de la población colombiana, en especial, la más pobre y vulnerable.
