Invaginación intestinal: cambio en su incidencia desde 1987 a 2008 / Intestinal invagination: change in its incidents from 1987 to 2008

En algunas series se ha apreciado una disminución en la incidencia de las invaginaciones intestinales en los últimos años. Además, la reciente introducción de nuevos tipos de vacunas contra el rotavirus hace que el seguimiento de la incidencia de las invaginaciones intestinales adquiera importancia. Para ello, son necesarios datos epidemiológicos locales fiables. Con el objetivo de conocer la evolución de la incidencia de las invaginaciones y su valor actual en nuestro área, hemos realizado un estudio retrospectivo de los pacientes menores de 3 años diagnosticados de Invaginación Intestinal y con confirmación por enema opaco o ecografía durante los últimos 21 años. En los resultados obtenidos se observa una disminución estadísticamente significativa de la tasa de incidencia, con una razón de incidencias de un año respecto al anterior de 0,82 (IC95% 0,78-0,86) pasando de una incidencia estimada para 1987 de 17,74 casos por cada 10.000niñas y 30,04 casos por cada 10.000 niños, a una incidencia estimada en 2008 de 0,27 casos por cada 10.000 niñas y 0,49 casos por cada 10.000niños.Concluimos que en nuestra serie se aprecia en el periodo estudiado un importante descenso de la incidencia de las invaginaciones intestinales, especialmente en los pacientes de menos de un año y estableciéndose la incidencia actual en 0,27 casos por cada 10.000 niñas y 0,49casos por cada 10.000 niños menores de 3 años (AU)

Some series have shown a decrease in the incidence of intestinal invaginations in last years. Moreover, the recent introduction of new types of rotavirus vaccines increases the interest of invagination’s incidence. To this purpose, reliable local epidemiological data are needed. In order to ascertain the trend in the incidence of invaginations and their current value in our area we have performed a retrospective review of patients under 3 years of age with the diagnosis of intussusception and confirms with barium enema or ultrasound examination during the past 21 years. Our results show a statistically significant decrease in the incidence rate, with an incidence rate of one year from the previous 0.82 (95%0,78-0, 86) from an estimated incidence for 1987 of 17.74 cases per10,000 girls and 30.04 cases per 10,000 boys, in 2008 an estimated incidence of 0.27 cases per 10,000 girls and 0.49 cases per 10,000 boys. We conclude that in our population during the study period a significant decrease of invagination’ s incidence has been seen, especially in patients younger than one year. The current incidence is 0.27 cases per 10,000 girls and 0.49 cases per 10,000 boys less than 3 years old (AU)

P300 endogen evoked potentials in somatization disorder: a controlled study.

INTRODUCTION: Somatization disorder (SD) is considered the most valid, reliable and consistent disorder over time from the entire group of somatoform disorders and the most disabling and expensive for the health system. The aim of this paper is to assess the discriminative, attentional and cognitive process in SD patients by auditory-stimulus P300 evoked potential. DESIGN: case-control study. SAMPLE: cases group is made up of 25 patients, selected from the Miguel Servet University Hospital Somatoform Disorder Unit, that fulfill DSM-IV-TR criteria of SD using EPEP psychiatric interview. Twenty-five healthy and volunteer individuals without psychiatric or neurological disorders or history of disease were selected as control group. Both groups were matched by gender and age. RESULTS: Mean P300 latency was significantly (p<0.01) higher in SD patients than in healthy people. The rest of variables studied (N100 latency, P200 latency, P300 amplitude in Pz) did not show any significant differences. CONCLUSIONS: SD patients show electrophysiological disturbances in the cognitive process of information.

Potenciales evocados endógenos P300 en el trastorno de somatización: un estudio controlado / P300 endogen evoked potentials in somatization disorder: a controlled study

Introducción. El trastorno por somatización (TS) se considera la entidad más válida, fiable y consistente a lo largo del tiempo de todo el grupo de trastornos somatomorfos, así como el más invalidante y el que mayor gasto sanitario produce. El objetivo de este trabajo es evaluar el procesamiento cognitivo atencional y discriminativo en pacientes diagnosticados de trastorno de somatización mediante el registro del potencial P300 con estímulo auditivo. Métodos. Diseño: estudio caso-control. Población: el grupo de casos está formado por 25 pacientes, seleccionados de forma sucesiva, procedentes de la Unidad de Trastornos Somatomorfos del Hospital Universitario Miguel Servet de Zaragoza y diagnosticados de trastorno de somatización según criterios DSM-IV-TR mediante la Entrevista Psiquiátrica Estandarizada Polivante (EPEP). Como grupo control se escogieron 25 sujetos sanos al azar, libres de patología psiquiátrica o neurológica, apareados por sexo y edad. Resultados. Se observa que la media de latencia de P300 es significativamente superior (p < 0,01) en pacientes con trastorno de somatización respecto al grupo control. En el resto de variables estudiadas (latencia de N100, latencia de P200 y amplitud de P300 en Pz) no se observan diferencias entre los dos grupos. Conclusiones. En los pacientes con TS existe una alteración electrofisiológica de los niveles del procesamiento cognitivo de la información
