Informe sobre el IV Congreso ISKO-España, EOCONSID'99 (Granada,22-24 d'abril de 1999)

El quart EOCONSID (Encuentro de Organización del Conocimiento en Sistemas de Información y Documentación), organitzat per ISKO-España (Capítulo Español de la International Society for Knowledge Organization), ha suposat «situar en el mapa» un congrés i una entitat que fins ara havien tingut poca projecció. Tot i organitzar les trobades regularment ¿cada dos anys¿ des del 1993, el poc coneixement de l'entitat i dels seus objectius comportava una assistència escassa de professionals a les trobades, limitada, es podria dir, als membres de l'entitat i als alumnes de la Universidad Carlos III, ¿entitat que havia acollit les segones i terceres trobades. Igualment, les actes publicades tenien poc ressò, tot i incloure contribucions d'un bon nivell de qualitat. El canvi en els òrgans de govern d'ISKO-España, el 1998, va replantejar la manera d'organitzar el congrés: es va decidir formar un equip independent de la junta directiva que s'hi pogués dedicar plenament i que garantís un major grau de professionalitat.

Invisible work, unseen hazards: the health of women immigrant household service workers in Spain

Backgroud: Household service work has been largely absent from occupational health studies. We examine the occupational hazards and health effects identified by immigrant women household service workers. Methods: Exploratory, descriptive study of 46 documented and undocumented immigrant women in household services in Spain, using a phenomenological approach. Data were collected between September 2006 and May 2007 through focus groups and semi-structured individual interviews. Data were separated for analysis by documentation status and sorted using a mixed-generation process. In a second phase of analysis, data on psychosocial hazards were organized using the Copenhagen Psychosocial Questionnaire as a guide. Results: Informants reported a number of environmental, ergonomic and psychosocial hazards and corresponding health effects. Psychosocial hazards were especially strongly present in data. Data on reported hazards were similar by documentation status and varied by several emerging categories: whether participants were primarily cleaners or carers and whether they lived in or outside of the homes of their employers. Documentation status was relevant in terms of empowerment and bargaining, but did not appear to influence work tasks or exposure to hazards directly. Conclusions:Female immigrant household service workers are exposed to a variety of health hazards that could be acted upon by improved legislation, enforcement, and preventive workplace measures, which are discussed.

A qualitative study about immigrant workers’ perceptions of their working conditions in Spain

Background: Spain has recently become an inward migration country. Little is known about the occupational health of immigrant workers. This study aimed to explore the perceptions that immigrant workers in Spain had of their working conditions.Methods: Qualitative, exploratory, descriptive study. Criterion sampling. Data collected between September 2006 and May 2007 through semi-structured focus groups and individual interviews, with a topic guide. One hundred and fifty-eight immigrant workers (90 men/68 women) from Colombia (n = 21), Morocco (n = 39), sub-Saharan Africa (n = 29), Romania (n = 44) and Ecuador (n = 25), who were authorised (documented) or unauthorised (undocumented) residents in five medium to large cities in Spain.Results: Participants described poor working conditions, low pay and health hazards. Perception of hazards appeared to be related to gender and job sector. Informants were highly segregated into jobs by sex, however, so this issue will need further exploration. Undocumented workers described poorer conditions than documented workers, which they attributed to their documentation status. Documented participants also felt vulnerable because of their immigrant status. Informants believed that deficient language skills, non-transferability of their education and training and, most of all, their immigrant status and economic need left them with little choice but to work under poor conditions.Conclusions: The occupational health needs of immigrant workers must be addressed at the job level, while improving the enforcement of existing health and safety regulations. The roles that documentation status and economic need played in these informants' work experiences should be considered and how these may influence health outcomes.

Complications following an accidental sodium hypochlorite extrusion: A report of two cases

Sodium hypochlorite (NaOCl) is the most commonly used solution in root canal treatments, as it is a low-cost method that displays a very effective antimicrobial activity against microbiota of infected root canals. However, this solution can cause complications especially due to its cytotoxic features. When this solution is injected into the adjacent tissues, the patient usually experiences intense pain, and an urgent treatment should be implemented in order to prevent a long-term sequelae. This paper describes the clinical features of two patients that experienced an accidental extrusion of NaOCl after endodontic treatment of varying severity and with different treatments. Furthermore, it shows the long-term neurologic injuries that this type of accidents may cause and a treatment protocol for these situations will be suggested.

Endocarditis infecciosa en un hospital terciario; aumento del número de casos asociados al medio hospitalario

Estudi prospectiu observacional realitzat entre gener 2003-juny 2010 amb casos diagnosticats de EI. Vam estudiar l’epidemiologia i els factors de risc de l'endocarditis infecciosa associada al medi hospitalari (EIAMH). Vam incloure 212 casos, el 34,9% eren EIAMH. Observarem un augment en la incidència en els darrers 4 anys (del 45,9% al 54,1%). La EIAMH s'ha associat a pacients grans i amb més comorbiditat. Staphylococcus aureus (21,7%) va ser el més freqüent. Aquests pacients van ser rebutjats per a la cirurgia amb major freqüència (40% vs 22%) i van presentar una major mortalitat (44,6% vs 19,6%) respecte al grup d'endocarditis comuniataria.

Disseny i implementació d'una base de dades relacional per al manteniment d'aparells d'una empresa

Així, per una banda, es tracta de fer l'anàlisi i disseny de la base de dades operacional, els scripts de creació necessaris per a crear la base de dades e implementar els procediments mitjançant els quals es gestionarà i accedirà a la informació de la base de dades. I per una altra banda, es tracta de fer l'anàlisi, disseny e implementació d'un magatzem de dades, per tal de poder explotar la informació per a la presa de decisions.

Endocarditis infecciosa por estreptococos beta-hemolíticos. Características y curso clínico de una cohorte multinacional.

Se trata de un estudio descriptivo de una cohorte prospectiva y multinacional de pacientes adultos diagnosticados de endocarditis infecciosa, de la cual se seleccionaron los pacientes diagnosticados de endocarditis infecciosa por estreptococos beta-hemolíticos y por estreptococos orales del grupo viridans. Los objetivos del estudio fueron describir las características clínicas, ecocardiográficas y el pronóstico de los pacientes con endocarditis infecciosa causada por estreptococos beta-hemolíticos y comparar dichas características con la endocarditis causada por estreptococos del grupo viridans. Las principales conclusiones fueron que la endocarditis infecciosa por estreptococos beta-hemolíticos es una entidad poco frecuente, que presenta un curso agresivo con una alta frecuencia de complicaciones y una necesidad quirúrgica alta.

Medicine and Science in a New Medical-surgical Context: The Royal College of Surgery of Barcelona (1760–1843)

Taking the Royal College of Barcelona (1760 -1843) as a case study this paper shows the development of modern surgery in Spain initiated by Bourbon Monarchy founding new kinds of institutions through their academic activities of spreading scientific knowledge. Antoni Gimbernat was the most famousinternationally recognised Spanish surgeon. He was trained as a surgeon at the Royal College of Surgery in Cadiz and was later appointed as professor of theAnatomy in the College of Barcelona. He then became Royal Surgeon of King Carlos IV and with that esteemed position in Madrid he worked resiliently to improve the quality of the Royal colleges in Spain. Learning human bodystructure by performing hands-on dissections in the anatomical theatre has become a fundamental element of modern medical education. Gimbernat favoured the study of natural sciences, the new chemistry of Lavoisier and experimental physics in the academic programs of surgery. According to the study of a very relevant set of documents preserved in the library, the so-called “juntas literarias”, among the main subjects debated in the clinical sessions was the concept of human beings and diseases in relation to the development of the new experimental sciences. These documents showed that chemistry andexperimental physics were considered crucial tools to understand the unexplained processes that occurred in the diseased and healthy human bodyand in a medico-surgical context. It is important to stress that through these manuscripts we can examine the role and the reception of the new sciences applied to healing arts.

Endocarditis infecciosa y complicaciones neurológicas

Las complicaciones neurológicas (CN) son frecuentes en la endocarditis infecciosa (EI) y ensombrecen el pronóstico. Nuestro objetivo ha sido analizar los grupos con (EICN) y sin ellas (EISCN) para determinar los factores relacionados con las CN y prevenirlas. Se observó que la EICN es un grupo menos comórbido, con localización predominantemente en cavidades izquierdas y tendencia a la afectación por Staphylococcus aureus. No se observó relación con un retraso diagnóstico de EI ni con demora en el antibiótico, y la antiagregación, anticoagulación y estatinas no mostraron efecto protector. Se rechazaron más a cirugía y la mortalidad tendió a ser mayor.

X-ray diffraction, thermal analysis, and Raman scattering study of K2BeF4 and comparation to other member of the (beta)-K2SO4 family with ferroelectric -paraelectric transition

Thermal analysis, powder diffraction, and Raman scattering as a function of the temperature were carried out on K2BeF4. Moreover, the crystal structure was determined at 293 K from powder diffraction. The compound shows a transition from Pna21 to Pnam space group at 921 K with a transition enthalpy of 5 kJ/mol. The transition is assumed to be first order because the compound shows metastability. Structurally and spectroscopically the transition is similar to those observed in (NH4)2SO4, which suggests that the low-temperature phase is ferroelectric. In order to confirm it, the spontaneous polarization has been computed using an ionic model.

Nitrogen incorporation effects in Fe(001) thin films

Nitrogen incorporates into Fe thin films during reactively sputtered TiN capping layer deposition. The influence that this nitrogen incorporation has both on the structure and magnetic properties is discussed for a series of Fe~001! thin films grown at different temperatures. A higher nitrogen content is accompanied by distortion in the Fe lattice and by reduction in the Fe magnetization saturation as well as in the effective anisotropy constant, K. The reduction of K brings as a consequence lowering in the coercive field with respect to equivalent Fe films with no nitrogen present.
