Influencia del grupo étnico en el uso de los servicios / No disponible

Introducción: los factores socioculturales (incluida la inmigración) en la utilización de los servicios sanitarios obligan a los equipos de Atención Primaria a plantear nuevas formas de trabajo. Objetivo: fundamentar la importancia que tienen las características socioeconómicas y culturales de la población como determinantes de la asistencia. Material y métodos: estudio descriptivo transversal de los menores nacidos en el año 2001 adscritos a un cupo de pediatría. Información recogida a través de un cuestionario pasado por la pediatra a los progenitores, así como mediante la consulta de las historias clínicas. Estudio realizado a partir de una muestra única. Resultados: la población gitana accede a la maternidad a edades inferiores al resto, su situación socioeconómica es más desfavorecida, acude sin cita con mayor frecuencia, realiza un uso inadecuado de los servicios de urgencias en mayor proporción, acude en menor grado a los controles del niño sano y cumple en menor medida los consejos pautados. La población inmigrante ocupa una posición intermedia entre la población gitana y la paya, asumiendo progresivamente las pautas y cuidados de salud del sistema español. Conclusiones: el grupo étnico y la situación socioeconómica condicionan el uso de los servicios de pediatría. La población gitana realiza un uso diferencial de los servicios sanitarios. La población inmigrante no es la mayor causante de la sobrecarga sentida por los profesionales. Parece conveniente reorientar la organización de la atención pediátrica para dar respuesta a las peculiaridades de cada grupo étnico, incorporando perspectivas grupales y comunitarias (AU)

Introduction: the socio-cultural factors (including immigration) influence the use of public health and make the medical services staff to implement new methods or ways of working. Objective: to asses the relevance of the socio-economic and cultural characteristics of the population in question as determining factors of the health services provided. Methodology: cross-sectional descriptive research of all the children born in the year 2001 assigned to a paediatrician. Information was gathered through a questionnaire handed over by the paediatrician to the parents as well as checking the clinical records of the child. The research was made from a unique sample. Results: the gipsy population reaches maternity earlier than the rest and its socio-economic situation is less favourable. They ask for medical services without appointment more frequently, making an inadequate use of the emergency units in a higher proportion, and they come for fewer controls of the Well Child Program, also displaying a higher degree of non-compliance about the advice given. Immigrants occupy an intermediate position between the gipsy and the non-gipsy population, progressively assuming the health guidelines and attendance of the Spanish health system. Conclusions: the ethnic group and the socio-economic situation definitely condition the use of the paediatric services. The gipsy population makes use of the health services in a different manner. The immigrants aren’t the main cause of the overload of work suffered by professionals. It would seem advisable to re-orientate paediatric services to respond to the peculiarities of each one of the ethnic groups, incorporating group and community based perspectives (AU)

Rickettsiae-like microorganisms in the midgut and other visceral tissues during development of Drosophila auraria.

Rickettsiae-like organisms (RLOs) were identified for the first time in midgut, Malpighian tubules, wreath cells (ventral nephrocytes), spermatogonia and gut muscles in a species of Drosophila. Their number in the midgut cells of Drosophila auraria significantly increased at the late third larval instar and at the beginning of pupation. The RLO population in the larval midgut followed the fate of their host cells and was destroyed during metamorphosis. The RLOs pass from the larval to the adult midgut via the RLOs existing in the 'regenerative cells', which will form the adult midgut during population. The total volume of RLOs per anterior midgut cell increased analogically in relation to the absolute volume of the host cells till the 130 h larval stage. However, during the late-third instar and at the beginning of pupation the total volume of RLOs per host cell significantly increased. The physiological significance of the latter data as well as the relationship between RLOs and host cells are discussed.

[Correlations between PRL and 17-beta-E in human breast cancer]. / Correlaciones entre PRL y E. 17 beta en el cáncer de mama humano.

The authors study the correlation existing between prolactin and E-17-beta in breast cancer. In both premenopausal and post-menopausal patients prolactin may be useful as an evolutive marker. Prolactin increases particularly as a consequence of the metastatic growth. E-17-beta shows no variation when studied during the luteal phase, diminishes after the extirpation of the primitive tumor, and augments again with metastases development. After chemotherapy the amount of E-17-beta becomes almost undetectable. No correlation was found between prolactin and E-17-beta; apparently, the prolactin increase does not depend directly from the amount of circulating estradiol, but relies on the activity of the hypothalamic-hypophyseal system. With regard to E-17-beta, this product also augments after ovariectomy, suggesting an ectopic production starting on adrenal gland precursors, perhaps modulated by prolactin.
