    Full Text Available En gran parte de la comunidad científica, así como del ámbito jurídico, al tratar del embrión no nacido, está vigente el criterio según el cual hay que definir el embarazo como el período que comprende sólo desde la implantación hasta el nacimiento natural. Esto lleva consigo otras novedades; por ejemplo, la redefinición de aborto como la eliminación del embrión sólo en ese período, o la extensión de la anticoncepción a cualquier medio que impida la unión entre los gametos como consecuencia de una relación íntima, o también que elimine el producto de la concepción antes de su implantación. De modo que la industria farmacéutica está lanzando al mercado, bajo el nombre de anticonceptivos, productos que actúan también mediante un mecanismo antiimplantatorio. Este hecho tiene grandes repercusiones éticas con relación al respeto del embrión, que obligan a reflexionar acerca de la valoración moral de la prescripción, dispensación y uso de estos medios. Ahora bien, ¿cuáles de los medios contraceptivos actualmente presentes en el mercado incluyen un efecto antiimplantatorio?, ¿qué mecanismos contribuyen a su acción farmacológica y en qué medida lo hacen? Esto es lo que hemos estudiado en este artículo, basándonos en la bibliografía científica disponible. Aunque no ha sido una tarea sencilla, puesto que los resultados aportados por la literatura varían mucho, se ha tratado de ofrecer una conclusión bastante precisa. Básicamente hemos cumplido un doble objetivo: actualizar y completar los estudios —pocos, parciales o lejanos en el tiempo— que tenían este mismo objeto; y ofrecer una valoración ética respecto al respeto de la vida naciente del uso de los anticonceptivos hormonales que pueden tener efecto antiimplantatorio.

    1986-01-01

    This article describes a typical evening at the Clinica del Pueblo in the Hispanic neighborhood of Adams-Morgan in Washington, D.c. The Clinical del Pueblo began operating in 1983 in response to the urgen medical needs of Central American refugees arriving in the Washington D.c. area. The refugees bring with them severe trauma, fear, and health problems caused by the civil was and exacerbated by inadequate or non-existant health services. Approximately 80,000 Salvadoran refugees live in the area. They do not receive adequate health care for 3 reasons. 1) Because the US goverment is unwilling to recognize them as true refugees, they live with the constant threat of deportatin back to the violence from which they have fled. 2) Refugees lack the ability to pay for private care. 3) Langauage and culture create frightening barriers to health care for the refugees. For those who do seek care, these barriers can lead to the inadequate or incomplete diagnoses and poor compliance and follow-up. Plenty International and the Central American Refugee Center responded to these problems by organizing a free clinic to provide not only medical care but also a training course for volunteers. The director of the clinic organizes the course, the classes are taught by a variety of people including the clinic's volunteer physicians, nurses, and public health educators as well as graduates of previus training courses and people from the wider community. The services of the clinic reach only a small portion of the population in need. However, the fact that free medical services are now available to some Central American refugees make the Clinica del Pueblo an important program.

  4. Síndromes hormonales paraneoplásicos Paraneoplastic hormonal syndromes

    Full Text Available En términos generales, podemos definir los síndromes paraneoplásicos como una combinación de efectos que ocurren lejos del lugar originario del tumor e independientemente de la repercusión local de sus metástasis. Los síndromes hormonales paraneoplásicos dependen de la secreción de péptidos hormonales o sus precursores, de citokinas y, más raramente, de hormonas tiroideas y vitamina D, que actúan de forma endocrina, paracrina o autocrina. A veces, los síndromes paraneoplásicos pueden ser más graves que las consecuencias del propio tumor primario y pueden preceder, ir en paralelo o seguir a las manifestaciones clínicas de dicho tumor. Es importante reconocer un síndrome hormonal paraneoplásico por diversas razones entre las que cabe destacar tres: 1 Puede conducir al diagnóstico de una neoplasia subyacente, benigna o maligna, previamente desconocida; 2 Puede dominar el cuadro clínico y, por tanto, inducir a errores en cuanto al origen y tipo de tumor primario y 3 Puede seguir el curso clínico del tumor subyacente y así ser útil para monitorizar su evolución. Son poco conocidos los mecanismos moleculares responsables del desarrollo de estos síndromes pero se considera que pueden ser inherentes a las mutaciones responsables del tumor primario o depender de factores epigenéticos como la metilación. En esta revisión contemplaremos los siguientes síndromes hormonales paraneoplásicos: hipercalcemia de malignidad, hiponatremia (secreción inadecuada de hormona antidiurética, síndrome de Cushing ectópico, acromegalia ectópica, hipoglucemia por tumores distintos a los de células de los islotes, ginecomastia paraneoplásica y una breve referencia final a otras hormonas (calcitonina, somatostatina y VIP.We can define paraneoplastic syndromes as a combination of effects occurring far from the original location of the tumour and independently from the local repercussion of its metastases.

    2005-01-01

    The Clinica del Lavoro was created in Milan at the beginning of the 20th century by Luigi Devotto, who deemed it essential for physicians and health researchers to get involved in the life and health problems of working populations. The main roles of the Clinica del Lavoro were to educate medical students and train physicians; study actual workplaces, examine health and safety hazards and their noxious effects; and create initiatives and services to protect and promote workers' health. Important scientific contributions were made in several fields, including chemical carcinogenesis, effects of mineral and biologicalfibers, mechanism of action of silica dust, methods for the detection and measurements of toxic substances in both the work environment and workers' biological media.

  6. Book review. Semeiologia Clinica Veterinaria. (a cura di Paolo Ciaramella

    Directory of Open Access Journals (Sweden)

    Manuel Graziani

    2014-09-01

    Full Text Available Il grado di specializzazione raggiunto nel settore clinico veterinario non è dissimile da quello presente in campo umano, soprattutto se si pensa agli animali d'affezione che sono oramai considerati parte integrante di una società moderna e civile in cui anche il fattore benessere animale ha acquisito importanza non secondaria, in particolare nell'allevamento degli animali da reddito. In questo contesto è sempre più richiesta la figura di uno specialista competente e aggiornato, in grado di risolvere in modo adeguato le problematiche che gli vengono proposte, in un mercato in concorrenza che non contempla imperizia, inesperienza e ignoranza professionale. Lo studio della semeiologia clinica è uno dei primi passi di questo lungo e affascinate cammino che permette di apprendere un metodo di analisi sistematico, affidabile, efficiente e accurato per educare il futuro medico veterinario verso le procedure della buona pratica clinica. La semeiotica insegna ad allenare i propri sensi: a guardare attraverso l'osservazione diretta e indiretta, a sentire ascoltando suoni o rumori, a percepire sensazioni tattili e, non da ultimo, a saper discernere con cognizione e competenza quando ricorrere alle indagini strumentali e di laboratorio; sempre e comunque nella consapevolezza che non possono in nessun modo sostituire l'esame fisico diretto del paziente. Paolo Ciaramella, professore ordinario di Clinica Medica Veterinaria all'Università Federico II di Napoli, presenta così il volume che ha curato: "L'idea di questo libro ha preso forma durante un simposio di medicina interna tenutosi a Torino nel 2008. Con alcuni colleghi presenti si pensò alla possibilità di elaborare un nuovo testo di Semeiotica Medica che potesse ampliare e aggiornare il glorioso Messieri e Moretti, non tanto perché esso avesse perduto il suo valore intrinseco, quanto piuttosto perché nel corso degli anni sono cambiate la patologia animale e con essa la semeiotica e la clinica

  7. Acta Clinica Croatica: progress of a journal step by step.

    2014-03-01

    The journal Acta Clinica Croatica (ACC) was founded in 1962 under the title Anali Bolnice Dr. M. Stojanović. In 1995, the title of the journal was changed into its present form and ever since all papers have been published in English. In 2000, the electronic (online) edition of the ACC was released in addition to the print version. The paper presents development of the journal from 1962 to 2012 based on the analysis of the following SCOPUS citation index parameters: type and number of documents published in the journal; number of citations; and number of domestic and foreign authors. The studied period was analyzed in three time segments: the period from 1995 to 1999, the period from 2000 to 2006 and the period from 2007 to 2012. The same parameters were analyzed in the Web of Science/SCI-Expanded bibliographic and citation index for the 2007-2012 period. The increasing number of documents, authors (both domestic and foreign) and citations demonstrates gradual rise in the quality, visibility and impact of the journal. The fifty years of experience show that a goal, at first very distant and almost unachievable, may be reached by progressing step by step.

    Haak, Daniel; Gehlen, Johan; Jonas, Stephan; Deserno, Thomas M.

    2014-03-01

    Imaging and image-based measurements nowadays play an essential role in controlled clinical trials, but electronic data capture (EDC) systems insufficiently support integration of captured images by mobile devices (e.g. smartphones and tablets). The web application OpenClinica has established as one of the world's leading EDC systems and is used to collect, manage and store data of clinical trials in electronic case report forms (eCRFs). In this paper, we present a mobile application for instantaneous integration of images into OpenClinica directly during examination on patient's bed site. The communication between the Android application and OpenClinica is based on the simple object access protocol (SOAP) and representational state transfer (REST) web services for metadata, and secure file transfer protocol (SFTP) for image transfer, respectively. OpenClinica's web services are used to query context information (e.g. existing studies, events and subjects) and to import data into the eCRF, as well as export of eCRF metadata and structural information. A stable image transfer is ensured and progress information (e.g. remaining time) visualized to the user. The workflow is demonstrated for a European multi-center registry, where patients with calciphylaxis disease are included. Our approach improves the EDC workflow, saves time, and reduces costs. Furthermore, data privacy is enhanced, since storage of private health data on the imaging devices becomes obsolete.

  10. [The role of the "Clinica del Lavoro Luigi Devoto" in international research].

    Bertazzi, P A; Forni, Alessandra M

    2003-01-01

    During its long history, the Clinica del Lavoro Luigi Devoto has produced numerous internationally recognized scientific contributions in the specific field of occupational medicine and health, and in other broader areas as, for example, immunology, toxicology, cytogenetics. Pivotal in this activity was the figure of Enrico C. Vigliani, director of the Clinica for over 35 years. We mention here, in particular, the results of the study of "early" markers of lead intoxication; the research on the carcinogenicity of benzene and aromatic amines; the study of the pathogenesis of silicosis and byssinosis; the study of cytogenetic damage after exposure to industrial toxic chemicals; the technical research for dust abatement in mines. Such research also played a major role in the development of pulmonary medicine, toxicology and immunology in Italy, and conferred scientific dignity on the newborn "industrial hygiene" discipline thanks to the work of Nicola Zurlo. Today, the Clinica's research is maintained at international standards especially by the work of thematic Research Centers recently established within the Clinica, covering fields such as occupational and environmental toxicology, occupational oncology, ergonomics, respiratory disease and allergy, psycho-social risk factors. These Centers are also devoted to the development of innovative methods in epidemiology, toxicology, psychology, molecular biology, and ergonomic measurement for the identification and evaluation of health risks at work.

    Full Text Available La gingivitis gravídica es una inflamación proliferativa, vascular e inespecífica con un amplio infiltrado inflamatorio celular. Clínicamente se caracteriza por una encía intensamente enrojecida que sangra fácilmente, por un engrosamiento del margen gingival y por hiperplasia de las papilas interdentales que pueden dar lugar a la aparición de pseudobolsas. La prevalencia varía entre el 35 y el 100% de las embarazadas con gingivitis previa. Aunque parece que durante el embarazo la susceptibilidad de los tejidos gingivales a la inflamación está relacionada con los cambios hormonales propios del mismo, el mecanismo exacto por el cual estas hormonas incrementan la inflamación gingival es desconocido. El cambio hormonal más significativo es el incremento en la producción de estrógeno y progesterona. La respuesta de los tejidos a las hormonas sexuales femeninas va a depender del tipo de hormona circulante, de la proporción de estrógeno/progesterona, así como de la concentración tisular de la hormona. Sus efectos a nivel del tejido gingival son variados y tienden a ser clasificados en cuatro grandes grupos: cambios vasculares, cambios celulares, cambios microbiológicos y cambios inmunológicos.Pregnancy gingivitis is a proliferative, vascular and non-specific inflammation accompanied by a wide cellular inflammatory infiltrate. Clinically it is characterized by an increased gingival redness and bleeding on probing index, gingival margin augmentation and hyperplasia of the interdental papillae. It is extremely common and affects 30-100% of all pregnant women. Even though it seems that during pregnancy susceptibility of gingival tissues to inflammation is related to altered hormonal levels, the exat mechanism by which they exert their effects remain unknown. The most significant hormonal change is the increase in the production of estrogens and progesterone. Tissue‘s response to female sex hormones depends on the circulating hormone

    The clinicopathological experience with 50 cases of pineal region tumours at Clinica Puerta de Hierro is presented. In this series, 88% of the patients were evaluated by CT-scan. Pineal region tumours make up approximately 0.7% of the intracranial expansive processes in the Spanish population. The largest group of lesions appearing in this localization is that of the germinomas (38%), followed by nontumoural lesions (20%) and tumours generally considered to be of the vicinity, such as meningiomas, gliomas and metastases (18%), tumours of the pineal parenchyma (14%), and non-germinoma germinal tumours (10%). In our series, in addition to an intracranial hypertension syndrome, an ophthalmological and, to a minor degree, an endocrinological syndrome predominate in germ-cell tumours, with a cerebellar syndrome appearing in gliomas of the pineal region. All the patients in the series diagnosed as having a germinoma and treated by irradiation are alive, and free of disease, after follow-up ranging from 2 to 20 years (mean: 8 years). The experience obtained with the present series supports the opinion that, in radiosensitive tumours, surgical resection adds no therapeutic benefit to treatment with radiotherapy alone. We suggest that when dealing with a tumour of the pineal region, CT-scan and clinical assessment now permit an initial selection of patients susceptible to surgery as a first therapeutic option, indicating those patients who, because they are considered to have either a "probable germinoma" or a "tumour of uncertain diagnosis", should undergo stereotaxic biopsy or trial radiotherapy and, only when this has proved a failure, should be subjected to open surgery.

    Electronic data capture (EDC) tools are designed to simplify data acquisition, improving data quality and managing clinical data electronically. Some data are collected from the laboratory information management system (LIMS), which is an important data source for a study. OpenClinica is an open source clinical data management system (CDMS) for web-based electronic data capture (EDC), which is used widely in academic clinical research. TranSMART is also an open source web-based platform used for the management and analysis of different data types common in clinical and translational research. Many LIMS use the Health Level 7 standard - Version 2.x (HL7) as a message exchange protocol. In this paper, we implement Mirth Connect as a Communication Server (CS) to convert these HL7 messages either to Operational Data Model (ODM) data for the automatic import in OpenClinica or tabular-delimited text format files, whose data is uploaded in tranSMART using the tMDataLoader tool.

    On occasion of the Centenary of the "Clinica del Lavoro Luigi Devoto", its researchers suggested that awareness of its historical identity and scientific development should constitute the basis for the future of the Institution. The directors of the Institute who have succeeded one to the other over the years have left a vivid report of the vast amount of work developed in several research fields and also of the original results achieved with significant impact on the scientific community and on society. Content analysis of "La Medicina del Lavoro" allowed us to shed light on strong bonds existing between manufacturing techniques, work organization and health, in the different political and social periods in which they developed. Many actions have been defined and several research subjects have been renewed (according to current demands and new methodological possibilities) between the past and the present, nevertheless many new approaches need to be taken in the fields of epidemiology, indoor air quality, ergophthalmology, muskuloskeletal disorders, environmental and molecular toxicology, and further research will be undertaken thanks to the potential of this discipline for the future. The aim of this report is also to express our thanks to all the medical and non-medical staff who have made their contribution over 100 years of engagement.

    The foundation of the Clinica del Lavoro by Luigi Devoto cannot be dated back to the specific date of an event or, worse, to the official inauguration as has happened so far. It can rather be considered as a process started on November 20, 1902 (date of the first resolution by the Milan Municipality Council), continuing with the national law n. 365 of July 9, 1905, then with the laying of the first stone on December 11, 1907 bearing the motto of the Milanese School "In aliis vivimus, movemur et sumus" and finally the official inauguration on March 20, 1910. The Founder Luigi Devoto was born in 1864 at Borzonasca (Genoa) and took a degree of medicine and surgery at the Genoa University in 1888. After a period in Prague and then in Genoa, he was appointed temporary teacher of medical pathology in Pavia. He published several scientific contributions in different fields of occupational health (lead intoxication, ankylostomiasis, strain cardiopathy, etc.) and in other branches (tuberculosis, pellagra, etc.) that he considered as indirectly work-related diseases. He died in Milan in 1936. Three issues characterize the ingenious intuition of Luigi Devoto and his thirty-year direction of the Clinica del Lavoro: 1. Full respect for the principles of discipline and scientific method suggested by Bernardino Ramazzini; 2. The extremely broad conception of the diseases that had to be considered as "workers' diseases"; 3. The constant social attention towards the application of scientific knowledge also through workers' information and updating of regulations to improve working conditions. Many of the conflicts and events associated with the foundation of the Clinica del Lavoro can be summarized in the name chosen by the Founder. Actually to those asking why "Clinic of Work" and not "Clinic of Workers", Devoto used to reply that it was work that was ill and therefore it was necessary to treat the work to prevent workers' illnesses.

Finally, the application of the proposed methods of study to the analysis of voltage stability in an electrical network derived from the Mexican Peninsular system is presented. The influence of voltage control devices in the stability phenomenon is discussed and a comparison with the results obtained by means of other analysis techniques are presented, specifically, the study of the Q-V curves and the modal analysis of the power flow equations. [Spanish] El trabajo de investigacion que se presenta en esta tesis se centra en el analisis de la estabilidad de voltaje de mediano plazo considerando el efecto de las caracteristicas de la carga y su interaccion con los modelos de dispositivos de control de voltaje en la red de transmision. Mas concretamente, se define y estudia un tipo de modelo de carga con caracteristicas deseables para el estudio de la estabilidad de voltaje; los modelos genericos de carga derivados de pruebas de campo o de la aplicacion de tecnicas de identificacion y se analiza la influencia de la aplicacion de dispositivos de control para mejorar los margenes de estabilidad del sistema. Se estudian, asimismo, alternativas al modelado de sistemas de potencia para el estudio de la estabilidad de voltaje en sistemas complejos. Se presenta, en primer lugar, un analisis fundamental de las caracteristicas de estabilidad de voltaje en un sistema simplificado de potencia y se introduce el metodo de analisis adoptado. Se muestra que el fenomeno de inestabilidad se manifiesta como una bifurcacion tipo singular inducida del modo critico de voltaje cuando se opera el sistema bajo condiciones de estres. A continuacion, se analiza la contribucion de la accion de dispositivos de control al margen de estabilidad y se deducen criterios de analisis de estabilidad basados en el estudio de dicho modo. Se propone, a continuacion, un modelo lineal del sistema de potencia con caracteristicas deseables para el estudio de la estabilidad de voltaje

    This paper aims to illustrate the conditions selected at the Clinica del Lavoro of the University of Milan to prepare and analyze a large number of fine dust samples produced over a period of about 50 years, that were initially used for studies within the Clinic performed in its own facilities, and since 1956 were sent to other Italian and overseas laboratories (Luxembourg, UK, Germany, Norway, Sweden, South Korea, USA). The total quantity of material distributed (with maximum size 7-10 microns) was about 2 kg and consisted of the following mineral and artificial compounds: quartz, HF-treated quartz, tridymite, HF-treated tridymite, cristobalite, chromite, anthracite, quartz sand for foundry moulds, sand from the Lybian desert, vitreous silica, pumice, cement, as well small quantities of metallic oxides, organic resins, chrysotile, crocidolite, fibres (vitreous, cotton and polyamidic). About half of the entire quantity of dusts produced consisted of partially HF-treated tridymite. Initially, research on the etiology of silicosis used quartz dust samples, simply sieved or ventilated (consisting of classes finer than 0.04 mm, containing a 15-20% respirable fraction). From 1956 to 1960 the dusts were produced by manual grinding in an agate mortar, below about 10 microns, starting from quartz from Quincinetto (near Ivrea, Province of Turin), containing about 99.5% quartz: particle size and composition were checked using an optical-petrographic technique, with identification of the free and total silica content. Subsequently, the dusts used for biological research were obtained by grinding coarse material with a cast iron pestle and planetary mills, agate and corundum jars. The grinding products were sized by means of centrifugal classification, using the selector developed by N. Zurlo, ensuring control of dust size both optically and by means of wet levigators and hydraulic classifiers (in cooperation with the Institute of Mines of Turin Polytechnic School). After 1990

Habitualmente, estos factores se presentan asociados a dietas cuali y cuantitativamente inadecuadas, originando alteraciones en el balance energético (consumo /gasto calórico y modificaciones en la composición corporal. En general, estas alteraciones se presentan combinadas e inducen reacciones hormonales tendientes a defender la homeostasis metabólica general. Los protagonistas de estos procesos adaptativos son un "circuito" constituido en el sistema nervioso central que se interrelaciona con otro "circuito periférico hormonal". Las manifestaciones del primero incluyen principalmente una atenuación funcional de los ejes hipotalamo-hipófiso-somatotrófico, prolactínico y tiroideo, amplificación de la secreción nocturna de la melatonina e hiperactividad adrenal. A su vez, las interrelaciones, a nivel hipotalámico, del eje CRH-ACTH-sistemas-opiodeo-dopaminérgico y la consiguiente inhibición de la secreción de Gn RH, constituye un mecanismo fisiopatológico crucial para el desarrollo de la disfunción gonadal.

    Full Text Available We conducted a clinical and electromyographical study in patients with Chagas' disease in the indeterminate or chronic stages of the illness. Altogether 841 patients were examined. Only 511 were admitted within the protocol; the remainder patients were rejected because they showed other causes able to damage the nervous system. Fifty two (10.17% out of the 511 patients showed signs and symptoms of peripheral nervous system involvement in the form of sensory impairment and diminished tendon jerks suggesting the presence of neuropathy. Forty five of them were submitted to a conventional electromyographical examination. Fifteen of mem showed normal results, while the remainder 30 disclosed a reduced interference pattern, being most of the remaining motor unit potentials fragmented or poliphasic, reduced sensory and motor conduction velocities and diminished amplitude of the sensory action potential. The findings suggest that some chagasic patients in the indeterminate or chronic stages of the disease may develop a clinical mild sensory-motor peripheral neuropathy.El estúdio presente fue diseftado con ei objeto de pesquizar Ia existência de manifestaciones clinicas en pacientes afectados por enfermedad de Chagas, en estádio indeterminado o crônico, que tuviesen, ai menos, 2 reacciones serologicas positivas.

Las fuentes geotermicas no tradicionales incluyen las partes profundas y los limites de los reservorios hidrotermales tradicionales, los sistemas en roca seca o humeda caliente, los yacimientos geopresurizados del Golfo de Mexico y los sistemas submarinos hidrotermales observados principalmente en la costa norte mexicana del Oceano Pacifico. La energia geotermica submarina surge por la existencia de rupturas profundas en el fondo marino, a lo largo de los centros de dispersion oceanicos entre las placas tectonicas. Estos sistemas tienen una longitud total aproximada de 65,000 Km. en la corteza oceanica. Hay dos tipos basicos de sistemas marinos existentes en el Golfo de California: los recursos profundos, localizados a lo largo de las cordilleras entre las placas de la corteza oceanica a mas de 2000 m bajo el nivel del mar, y los recursos poco profundos cerca de las plataformas continentales, entre 20 y 50 metros de profundidad. El calor submarino poco profundo tambien se relaciona con fallas y fracturas en el fondo del mar cerca de algunas costas. Este subsistema se encuentra tambien en la costa de Punta Banda en Ensenada, Baja California. El potencial preliminar de la energia contenida en tales reservorios se estima, en promedio, en 1120 MWt por cada km3 de roca submarina. Las caracteristicas quimicas especificas de las aguas hidrotermales encontradas en esos sistemas oceanicos indican que las interacciones agua-roca, ocurren bajo condiciones de presion y temperatura altas. La energia geotermica submarina soporta ricas variedades de comunidades biologicas a profundidades donde las plantas no tienen acceso a la luz solar para realizar la fotosintesis. Hay indicios de que las posibles condiciones para la sintesis de sustancias y elementos quimicos necesaria para el origen de la vida primitiva, pudieron ser los sistemas hidrotermales submarinos.

Esperienze, queste, che hanno in comune il fatto di essere il prodotto di discorsività “scientifiche”, positiviste, che hanno assunto un certa autorità nel parlare di determinate alterità – il medico con il “suo” folle e l’antropologo con il “suo” selvaggio –, e che sono state esperite lungo la storia delle due discipline, particolarmente in età moderna, quando stabilirono il loro apparato epistemologico e metodologico. Con la post-modernità, si realizzò quindi una svolta epistemologica secondo cui il ricercatore e l’analisi da lui prodotta non possono essere oggettivi: tanto la soggettività dello studioso quanto quella dell’oggetto di analisi contribuiscono a modificare il contesto e l’interazione tra i soggetti. La psicoterapia e l’antropologia verranno quindi considerate sul piano fenomenologico, e la produzione di sapere diverrà polifonica e condivisa.

    Full Text Available Durante el desarrollo embrionario se establecen múltiples interacciones entre hormonas, factores de crecimiento (FC y diferente tipo de moléculas, con lo cual se genera una serie de señales que desencadenan el reconocimiento materno de preñez (RMP entre los días 15 y 17, momento en el cual se genera un “periodo crítico”, cuando el endometrio libera la hormona prostaglandina F2a (PGF2apara causar regresión del cuerpo lúteo (CL, en el cual se sintetiza progesterona (P4, hormona encargada de favorecer un adecuado ambiente uterino para el desarrollo embrionario y el mantenimiento de la preñez. El embrión en desarrollo genera señales antiluteolíticas que bloquean la producción de la PGF2a, por lo que se podría sugerir que el mantenimiento de la preñez es dependiente de la efectividad de este bloqueo, entre otros factores; el cual es generado por la acción del Interferón tau (IFN-t, producido en las células mononucleares del trofoblasto embrionario. Este bloqueo garantiza la integridad del CL y de esta forma la producción normal de P4. Por lo anterior se podría pensar que la manipulación estratégica apoyada hormonalmente, mejora las condiciones para el efectivo bloqueo de los agentes luteolíticos que tienen su mayor actividad durante el llamado “periodo crítico”, con lo cual se mejora la tasa de sobrevivencia en programas de transplante embrionario ya que se crearía un ambiente uterino adecuado para el establecimiento y normal desarrollo del embrión. Por esto mismo, últimamente se han planteado mecanismos de apoyo hormonal que causan un bloqueo apropiado en cuanto a la producción de PGF2a uterina durante los días15 y 17 del ciclo estral.

    Full Text Available A wide variety of opportunistic pathogens has been detected in the tubing supplying water to odontological equipment, in special in the biofilm lining of these tubes. Among these pathogens, Pseudomonas aeruginosa, one of the leading causes of nosocomial infections, is frequently found in water lines supplying dental units. In the present work, 160 samples of water, and 200 fomite samples from forty dental units were collected in the city of Barretos, State of São Paulo, Brazil and evaluated between January and July, 2005. Seventy-six P. aeruginosa strains, isolated from the dental environment (5 strains and water system (71 strains, were tested for susceptibility to six antimicrobial drugs most frequently used against P. aeruginosa infections. Susceptibility to ciprofloxacin, followed by meropenem was the predominant profile. The need for effective means of reducing the microbial burden within dental unit water lines is emphasized, and the risk of exposure and cross-infection in dental practice, in special when caused by opportunistic pathogens like P. aeruginosa, are highlighted.Uma ampla variedade de patógenos oportunistas tem sido detectadas nos tubos de alimentação de água dos equipos odontológicos, particularmente no biofilme formado na superfície do tubo.

    The proposed methodology described ahead (Moya et al.,1996; Moya et al.,1997a, 1997b and 1997c) simplifies the construction of production characteristic curves of geothermal wells and of its associated thermal productivity, in requiring one single measurement of mass flow-pressure-enthalpy (W-P-h) at the wellhead. Therefore it is an ecological option, technically and economically more feasible. On the other hand, the methodology also allows to diagnose the rocky formation absolute permeability in the well feeding zone. This permeability is usually determined through well bottom pressure tests, than in some cases are difficult to interpret. The permeability inferred by means of the proposed technology represents a complementary tool for these field tests and for the laboratory measurements on drilling cores. [Espanol] La metodologia propuesta que se describe a continuacion [Moya et al., 1995d; Moya et al., 1996; Moya et al., 1997a, 1997b y 1997c] simplifica la construccion de curvas caracteristicas de produccion de pozos geotermicos y de su productividad termica asociada al requerir solo una medicion de flujo masico-presion-entalpia (W-P-h) a boca de pozo. Es por tanto una alternativa ecologica, tecnica y economicamente mas factible. Por otra parte, la metodologia tambien permite diagnosticar el valor de la permeabilidad absoluta de la formacion rocosa en la zona de alimentacion al pozo. Esta permeabilidad se determina usualmente a partir de pruebas de presion a fondo de pozo que en algunos casos son dificiles de interpretar. La permeabilidad inferida mediante la metodologia propuesta representa una herramienta complementaria a estas pruebas de campo y a las mediciones de laboratorio sobre nucleos de perforacion.

    Full Text Available Infectious diseases continue to represent an important preventive and clinical problem especially in the light of the emergence of new pathogens, of the return of infrequent pathogens and of the increased risk of infective pathologies associated with migratory flow. Another critical point is represented by the possible insurgence of infections due to agents used in bioterrorism. More than ever it is indispensable for our country to define a network of structures able to give an organized response to these relevant problems both in terms of prevention and assistance. It is therefore important to define a protocol for clinical microbiology on a national basis that responds to different levels of activity. Keeping in mind that the fundamental objectives of microbiology are: - diagnosis of infective diseases - determination of resistance to antimicrobic drugs as a valid instrument to allow the clinician to proceed with specific treatment - control of infection spreading in the sanitary structures (hospital infections - to develop front line defence in new infections and bioterrorism, in collaboration with the department of prevention - to be a reference centre for specific training The principals on which one must base the reorganization are essentially three: 1. to configurate the microbiology service on the basis of real needs of the local population 2. to give qualitatively optimal results in real time 3. supporting “good clinical practice” to assure adequate patient results and acceptable costs for the regionale sanitary system (SSR The organization of microbiology should therefore foresee a microbiology department, structured on a provincial basis or a vast area including a structured centralized complex with peripheral structures (even simplified. This must integrate actively with the department of prevention in regard to the dynamics of infectious diseases in the territory and with the Division of Infectious Diseases (where this exists. In parallel an active interaction with research structures (IRCCS and University present in the territory to enable the coordinated implementation of the guidelines of research and its relapse on diagnostic exams. Keeping in mind that the quality of diagnostic performance is closely linked to the professional experience of the operators it is good practice centralizing some diagnostic procedures by identifying a reference centre. In a regional network organized in this way it is important to include a coordinating structure, since it is necessary to activate a complete level of communication, information exchange, activity planning, and complete problem solving.

    Full Text Available Several reports have related Legionella pneumophila with pneumonia in renal transplant patients, however this association has not been systematically documented in Brazil. Therefore this paper reports the incidence, by serologycal assays, of Legionella pneumophila serogroup 1 in these patients during a five year period. For this purpose sera from blood samples of 70 hospitalized patients with pneumonia from the Renal Transplant Unit of Hospital das Clinicas, FMUSP collected at the acute and convalescent phase of infection were submitted to indirect immunofluorescence assay (IFA to demonstrate anti-Legionella pneumophila serogroup 1 antibodies. Of these 70 patients studied during the period of 1988 to 1993,18 (25.71 % had significant rises in specific antibody titers for Legionella pneumophila serogroup 1. Incidence was interrupted following Hospital water decontamination procedures, with recurrence of infections after treatment interruption. In this study, the high susceptibility (25.71% of immunodepressed renal transplant patients to Legionella pneumophila serogroup 1 nosocomial infections is documented. The importance of the implementation and maintenance of water decontamination measures for prophylaxis of the infection is also clearly evident.Embora vários trabalhos tem mostrado a presença de Legionella pneumophila associado a pneumopatias infecciosas em transplantados renais, tal associação não fora antes realizado de maneira sistemática no Brasil.

    Plant survival to biotic stresses results from various defence strategies. Depending on the pathogen and nature of the parasitism, a plant will adapt its responses through a fine tuning regulation of defence mechanisms under the control of its hormones whose functions will be reoriented. Salicylic acid, jasmonic acid and ethylene drive signalling pathways, the role of which is well established in plant resistance. However, additional hormones, including abscisic acid, seem to have an essentia...

    Full Text Available Effects of Different Hormonal Balances on the Microprogation of Cv. Hybrid FHIA-01 (Musa sp.. Different hormonal balances were evaluated to develop a growth medium to effectively multiply the FHIA-01 hybrid in vitro The most striking results of this study are: the almost complete inhibition of the shoot proliferation by BAP; the total root inhibition by the concentration 10 μM BAP+10 μM MemTR and the improvement of the mean shoot proliferation (5,4 shoots/explants by adding the same concentration. Adding MemTR improves the hormonal balance for the proliferation of shoots of FHIA-01. At least 1 μM of IAA is needed as auxin source, to reach the same result. In this study, we identified some factors related to the experimental conditions, such as light and darkness that seemed to be necessary for the organogenesis of FHIA-01. The cultures had to be placed 15 days in darkness and 15 days in light conditions.

    Introduccion. Muchos de los instrumentos neuropsicologicos utilizados en España se han normalizado en poblacion hispanohablante procedente de Estados Unidos y Sudamerica, con grupos de edad y caracteristicas restrictivas. Utilizar este tipo de normas disminuye potencialmente su representatividad, la interpretacion de los resultados y las decisiones clinicas. Este estudio se enmarca dentro del proyecto Normacog, con el fin de estandarizar instrumentos neuropsicologicos en una muestra representativa de la sociedad española. Objetivo. Presentar la metodologia de normalizacion llevada a cabo en el proyecto Normacog y las caracteristicas sociodemograficas de la poblacion española y de los participantes incluidos en el estudio. Sujetos y metodos. Se reclutaron 711 participantes (rango: 18-90 años) de diferentes areas geograficas de España, incluyendo los datos sociodemograficos, medicos, habitos habituales, lengua materna, bilinguismo y dominancia manual. Cada participante completo 19 instrumentos que evaluaban un amplio rango de dominios cognitivos, como memoria verbal y visual, atencion, funciones ejecutivas, velocidad de procesamiento o fluidez y denominacion verbal. Resultados. La muestra final normativa refleja las caracteristicas sociodemograficas y la representatividad de la poblacion española de acuerdo con los rangos de edad, educacion y sexo. Conclusiones. Se describe la metodologia de normalizacion y las caracteristicas de la muestra incluida en el estudio multicentrico Normacog, mediante el cual se llevara a cabo la estandarizacion y normalizacion de instrumentos neuropsicologicos, teniendo en cuenta las caracteristicas sociodemograficas propias de la poblacion española. El proyecto Normacog proporciona datos normativos adecuados a nuestro medio cultural, y es esencial para poder realizar un diagnostico clinico y neuropsicologico fiable.

    Objetivo. Identificar las caracteristicas clinicas que predicen una respuesta favorable al tratamiento con onabotulinumtoxina A (OnabotA) en pacientes con migraña refractaria. Pacientes y metodos. Estudio retrospectivo de pacientes con migraña refractaria que recibieron al menos dos infiltraciones de OnabotA entre los años 2008 y 2012. Los pacientes fueron divididos en respondedores y no respondedores a OnabotA y se compararon entre ambos grupos, y de forma retrospectiva, una serie de caracteristicas clinicas consideradas predictoras de respuesta en estudios previos: localizacion unilateral de la cefalea, presencia de tension muscular pericraneal, tipo de dolor (implosivo, explosivo u ocular), tiempo de evolucion de la migraña (menor o mayor de 10 años) y abuso de medicacion analgesica. Resultados. Se incluyeron 39 pacientes (35 mujeres) con una edad media de 46 años. En 18 pacientes (46,2%) se observo una reduccion mayor del 50% en el numero de dias de cefalea/mes (pacientes respondedores). Al analizar las diferentes caracteristicas de la migraña, se observo que todas ellas fueron igualmente prevalentes en los pacientes respondedores y en los no respondedores (p > 0,05): localizacion unilateral (66,7% frente a 66,6%, respectivamente), dolor implosivo (27,8% frente a 38,1%), presencia de tension muscular pericraneal (33,3% frente a 38,1%), tiempo de evolucion de la migraña mayor de 10 años (77,8% frente a 69,2%) y presencia de abuso de medicacion analgesica (50% frente a 81%). Conclusion. En esta serie de pacientes no se ha identificado ningun rasgo clinico que permita predecir en pacientes con migraña refractaria una respuesta favorable al tratamiento con OnabotA.

    ões desportivas para a população investigada.Para comprender las lesiones deportivas (LD es necesario cuantificarlas, asociandolas a factores causales particulares al esporte. Aún así, faltan registros sobre estas patologías en las instituciones deportivas, sobretodo en el atletismo brasileño, donde pocos son los clubes que poseen servicios de asistencia de la salud. La ausencia de tales registros, estudios en el área de Salud Pública, se utilizan otros recursos epidemiológicos para colectas, tales como las consultas de morbilidad referida. A partir de esta escasez de información y de la facilidad de obtención de datos junto a los propios atletas, se objetivó, para esta pesquisa, levantar informaciones sobre las LD referidas por los atletas de alto rendimento, retrocediendo ocho meses, y comparándolas con los registros de historias clínicas. Por lo tanto, fueron tomados veinticinco atletas de elite, dieciseis de género masculino y nueve del femenino, con edades de 25,7 ± 4,4 años, altura de 1,74 ± 0,10 m, peso 70,4 ± 13,15 kg e tiempo médio de entrenamiento de 8,38 ± 4,06 años. Dos fisioterapeutas fueron entrenados separadamente para recolectar información sobre LD. Uno de ellos en historias clinicas y el otro de los propios atletas a través de entrevistas (Interrogatorio de Morbidade Referida - IMR. El estudio de concordancia de respuestas para las dos formas de colecta fué realizado por el test de proporción binomial, estabeleciendose límites de 95% de confianza para la concordancia. Los resultados mostraron que en todas las variables estudiadas los valores estaban dentro de los límites de confianza estabelecidos para los tests estadísticos, siendo: 88,33% para las variables tipo de lesión o agravio y mecanismo de lesión o aumento de los síntomas, 90% para la variable calidad del reintegro a las actividades deportivas el 91,67% para las variables local anatómico y período de entrenamiento.

    Introduccion. El desarrollo de la resonancia magnetica estructural y de nuevos metodos de analisis ha permitido examinar, como nunca antes, las bases neuroanatomicas del trastorno por deficit de atencion/hiperactividad (TDAH). No obstante, poco se sabe todavia sobre la relacion de los sintomas clinicos y las disfunciones neuropsicologicas caracteristicas del TDAH con las alteraciones neuroanatomicas observadas. Objetivo. Explorar la relacion entre neuroanatomia, clinica y neuropsicologia en el TDAH. Desarrollo. A nivel de grupo, existen diferencias marcadas entre el cerebro de niños adolescentes y adultos con TDAH y el cerebro de personas con desarrollo tipico. Estas diferencias se observan transversal y longitudinalmente en todas las medidas, tanto de la sustancia gris como de la sustancia blanca. Aunque todavia escasa, cada vez existe mayor evidencia que señala que estas diferencias se relacionan con los sintomas nucleares del trastorno y con el grado de disfuncion clinica. Tambien parecen asociarse con el funcionamiento cognitivo (principalmente, atencion y control inhibitorio). Conclusiones. La relacion entre los distintos niveles de analisis de estudio del TDAH acerca la investigacion a la clinica y permite comprender y tratar mejor el trastorno. Aunque el avance en este campo es innegable, todavia son muchas las cuestiones que hay que explorar y profundizar en mayor detalle. Se requiere comprender mejor la asociacion entre las medidas neuroanatomicas y cada dimension sintomatologica, y la relacion con otros procesos neuropsicologicos tambien implicados en el trastorno.

    Introduccion. Se define siringomielia como una cavidad que contiene liquido cefalorraquideo dispuesta en el interior de la medula espinal. Objetivo. Describir las caracteristicas clinicas de una serie de pacientes con siringomielia, su diagnostico y tratamiento. Pacientes y metodos. Estudio descriptivo retrospectivo realizado mediante la revision de historias clinicas en nuestro centro. Resultados. Se revisaron 25 pacientes diagnosticados de siringomielia. En cinco el diagnostico fue casual y ocho presentaban una patologia grave previa (tumoral, osea o vascular). Dos pacientes comenzaron con hidrocefalia y clinica de hipertension intracraneal y unicamente dos destacaban cefalea como unico sintoma. Cuatro presentaron escoliosis progresiva, dos de ellos como queja inicial, y precisaron cirugia con artrodesis y uso de corse, respectivamente. Destaca la precocidad del diagnostico. La mayoria presentaba unicamente perdida de fuerza leve, con potenciales somatosensoriales y electromiograma normales. En todos se hicieron controles con resonancia magnetica. Ocho pacientes precisaron craniectomia descompresiva con laminectomia posterior C1-C2, con drenaje de la cavidad siringomielica en cuatro. Nueve requirieron valvula de derivacion y dos precisaron, ademas, ventriculostomia. Conclusiones. La presencia de siringomielia en pediatria es rara, y se asocia generalmente a malformaciones en la fosa posterior y antecedentes de disrafismo espinal. Destaca la escoliosis progresiva como posible manifestacion aislada. Un abordaje multidisciplinar con controles radiologicos seriados y la valoracion por servicios de neurologia y neurocirugia pediatricos son mandatorios para su seguimiento.

    Full Text Available El germen de maíz desgrasado (GMD es un subproducto que se obtiene al elaborar harina cruda o precocida y extraer el aceite de maíz. Este subproducto se usa exclusivamente en la alimentación animal, debido a que es un material heterogéneo con alto contenido de salvado. El principal obstáculo para usarlo en la formulación de alimentos es que los fragmentos de fibra de la cáscara, modifican las características sensoriales y funcionales de los productos. Para evitar esta limitante, en este trabajo, se trató de eliminar los fragmentos de fibra y de incrementar la concentración de proteína. Para esto, el material extraíble (ME rico en grasa y el germen industrial desgrasado (GD fueron sometidos a fraccionamientos mediante separación en tamices, aspirado y molienda. El rendimiento en fracciones de GMD obtenidas a nivel de laboratorio GD1 e industrial GD2 respectivamente, fue de 44,76% y 78,02%. La fibra se redujo en un 18,45% y en un 41,61% y se aumentó la proteína en 7,40% y en 19,56% para las fracciones GD1 y GD2 respectivamente. La calidad de la proteína medida por la eficiencia proteica (PER varió de 2,57 a 2,84 lo que resultó ser 16 veces superior a la de la harina de endospermo de maíz blanco (PER 0,16 y la digestibilidad aparente de las fracciones GD1 y GD2 dio valores superiores al 86%, lo que indica que el fraccionamiento es una tecnología sencilla que mejora considerablemente la calidad de las proteínas del germen, el color y los índices de solubilidad y absorción de agua.

    The electric characteristics of hydroxyapatite films were studied (HAP) deposited on metallic substrates oxidized naturally. The substrates was made of steel 316L and of titanium. These materials are used in reconstructive surgery for prosthesis and osseous implants. The studies were carried out with the techniques of potentiostatic polarization and faraday impedance. The potentiostatic polarization reveals that the very well-known piezoelectricity of the HAp subsists after the coating processes (it captures thermal and spray-pyrolysis). Its also revealed a semiconductor behavior of the HAp that until now had not been reported. This characteristic is important, by its relationship with the stability of the HAp coating in front of corrosion processes in the alive tissues. The results of the impedance tests were mathematically analyzed starting from the Nyquist diagrams, of Bode and of power. The physical interpretation is presented under the form of equivalent circuits (CE). In the case of the HAp on a steel 316L substrate, the CE is a Rancles-Voigt module that corresponds to the behavior of a dielectric with flights. In the case of the titanium substrate an element of constant phase appears to high frequencies (CPE), in series with the Rancles-Voigt module. The CPE reveals the presence of a rectifier of the metal/SC-n type that only it could be located in the interface among the titanium and its natural oxide (TiO{sub 2}). The absence of the CPE in the case of the steel 316L substrate indicates that the natural oxide (Cr{sub 2}O{sub 3}) it doesn't form with the steel a Schottky diode, possibly because the chromite is as a SC-n degenerate. On the interface Ti/TiO{sub 2} exists results qualitatively identical by other researchers that have worked with the same impedance technique, but applied by humid via (EIS). The CE that have proposed are based on the anodic processes of accretion/dissolution of the film at low pH. This proposal is questioned by our results, obtained under non electrochemical conditions. In accordance with our interpretation, the answer in frequencies of the system Ti/TiO{sub 2}/HAp can separate in two well differentiated ranges: that of low frequency, where operates the CE Rancles-Voigt that contains the information on the HAp; and that of high frequency, where operates the CPE that contain the information on the union Ti/TiO{sub 2}. This spectral resolution is, in principle, very convenient. However, when it is sought to characterize the HAp and the study should be carried out at low frequencies, the necessity to obtain an acceptable statistics implies a great lost of time. This unfavorable circumstance cannot be obviated by means of the Kramers-Kronig transformations, clearly inapplicable in these systems. (Author)

    Active carbon (AC) is a solid possessing two properties which make it extremely useful in treating water. The first consists in trapping all kinds of organic contaminants in its walls so avidly that it can leave water practically free of such compounds. The second consists in destroying the free waste chlorine which has failed to react once it has completed its disinfecting action. As a result, virtually all industries requiring potable water employ active carbon as one of their basic treatment methods. (Author) 7 refs.

    The Argentinean northwest (NOA) is an exceptional zone to use solar energy, because of its climate and its solar radiation levels. The aim of this paper is to analyze the use of low temperature solar heating system by mean of a plastic collector. The system proposed includes: a) Solar collectors built with plastic bags, welded in such a way that water, introduced at the top, falls by gravity through a zigzag long path. Each collector is fed by drip feed irrigations. b) Hot water storage and c) Water pump, hydraulic circuit and electronic controls. Two ways of use are proposed: as a water solar heating and as a system to heat greenhouses. In this second case, if during the day the air temperature inside the greenhouse is higher than the water storage temperature, the water will be heated in the bags. During the night the bags work as heat exchanger. When the temperature inside the greenhouse needs to be maintained at a constant value, the heating system is combined with a gas water heating. The equipment is described, performances are compared for both uses and the global heat exchange coefficient is calculated. The system's behavior inside a greenhouse is analyzed in two different situations. The utilization of plastic solar collectors has demonstrate to be a valid alternative for low temperature solar energy uses, specially in heating agricultural spaces. [Spanish] La region del Noreste Argentino (NOA), por su clima y muy en particular por los niveles de radiacion solar que posee, es una zona excepcional para el aprovechamiento de la energia solar. El objetivo de este trabajo es analizar el uso de la energia solar a baja temperatura mediante un colector de plastico. El sistema propuesto incluye: a) Colector solar construido con una bolsa de plastico soldada en forma tal, que el agua que se introduce por la parte superior cae por la gravedad siguiendo un camino en zigzag. Cada colector se alimenta mediante goteros de riego autocompensados. b) Almacenamiento del agua caliente y c) Bomba, circuito hidraulico y controles electronicos. Se plantean dos condiciones de uso: como calentador solar de agua y como sistema para calentar invernaderos. En este segundo caso si durante el dia la temperatura interior del invernadero es mayor que la temperatura del agua en el almacenamiento el funcionamiento del sistema preve que el agua circule a traves de las bolsas colectando energia; durante la noche las mismas bolsas actuan como intercambiadores de calor. Cuando es indispensable mantener la temperatura en el interior del invernadero dentro de cierto rango, el sistema de calentamiento se combina con un calentador de agua a gas natural. Se describen las instalaciones, se comparan rendimientos instantaneos y globales de los colectores solares para las dos situaciones analizadas y se calcula el coeficiente global de transferencia de calor cuando las bolsas actuan como intercambiadores de calor. Se analiza tambien el comportamiento integral del sistema dentro del invernadero para dos situaciones diferentes. El empleo de los colectores solares de plastico ha demostrado ser una alternativa valida para el uso de energia a baja temperatura, especialmente para la calefaccion de locales agricolas.

With the information of the spectrum it was calculated the average energy of the neutrons of each source. By means of the fluence coefficients to dose it was determined, for each one of the studied sources, the fluence factors to dose. The calculated doses were H, H{sup *}(10), H{sub p,sIab} (10, 0{sup 0}), E{sub AP} and E{sub ISO}. During the phase of the calculations the sources were modeled as punctual and their characteristics were determined to 100 cm in the hole. Also, for the case of the sources of {sup 239} Pu Be and {sup 241} Am Be, were carried out calculations modeling the sources with their respective characteristics and the dosimetric properties were determined in a space full with air. The results of this last phase of the calculations were compared with the experimental results obtained for both sources. (Author)

    The laws on radiological protection have special characteristics. They can exist laws that regulate dangerous activities that will be also applicable, if it corresponds to the activities that involve radioactive materials. But a law of radiological protection should exist. It foresees the existence of an appropriate regulatory body and specialized institutions, definitions, infractions and sanctions then the respective regulations will be elaborated for the different applications. The objective is to contribute to the development of the nuclear energy in the country and to provide the regulatory basis that assures a reasonable security for radioactive installations. The essential objectives of these laws are: 1. to establish the legislative framework for the development and employment of nuclear energy, without risks, according with treaties and conventions that the countries have approved. 2. To fix the fundamental principles and the conditions of their setting in practice allowing to a specific regulation determining application procedures. 3. To create a structure of regulation of enough authority to be able to control and to watch over in an effective way the authorized activities 4. To guarantee an appropriate financial protection against the derived damages of accidents or nuclear incidents. (author)

    Full Text Available A morphologic, petrographic and crystallographic study was performed in some representative samples of disseminated graphite of the Cerro Osumita, Cojedes State, Venezuela with the aim of establishing the degree of mineral crystallinity (graphitization and the highest temperature reached by the rock. From the original rock (La Aguadita quartz-feldespatic-graphitic Gneiss, fractions enriched in graphite were obtained by means of leaching with HCI-HF and physical procedures (flotation and accumulation in liquid interfaces. The isolated graphite was analyzed by X-Ray Diffraction, whereas morphology was studied by Scanning Electronic Microscopy (SEM. The mineralogical association exhibited by the gneiss (quartz- oligoclase- hornblende (green- microcline - chlorite- biotite- epidote allows establishing the metamorphism of the rock in the upper zone of the green schist facies, in the biotite zone. Graphite grains present aspect of flakes, with a concentration oscillating between 7 and 10% in weight. The used enrichment process allowed obtaining fractions with more than 92% in graphi- te. Under Scanning Electronic Microscopy, graphite samples showed morphology dominantly as sheets, very well defined and ordered. The crystallinity index (measured by XRD is around 58 and 60, with a mean graphitization degree of 60, suggesting a high order in the crystalline net. The higher temperature reached by the rock, according to the graphitization degree, is of 472 f 27 "C.Muestras representativas del grafito diseminado del Cerro Osumita, Estado Cojedes, Venezuela, fueron objeto de un estudio morfológico, petrográfico y cristalográfico, con el fin de establecer el grado de cristalinidad del mineral y la temperatura máxima alcanzada por la roca.

Patients and methods: The sample studied was a crosssectional cohort of women > 18 years of age, BMI ≥ 25 < 40 kg/m², prior to starting a weight control program. Data collected were: demographic characteristics, blood pressure, anthropometric parameters, physical activity data, and biochemical, hormonal and inflammatory biomarkers. Results: The study involved 104 women with a mean age of 48.4 ± 9 years and a BMI of 29.8 ± 3.5 kg/m². Some 48% of the women studied were in menopause. Some 8.9% had hyperinsulinemia. The mean ghrelin value was 38.8 ± 33.6 pg/ml; there was no correlation between ghrelin levels and anthropometric and biochemical variables. CRP, leptin, adiponectin, resistin, IL6, IL10, and PAI1 were 3.0 ± 2.7 mg/dl, 36.3 ± 19.5 ng/ml, 8.3 ± 4.5 mg/ml, 24.3 ± 23.2 ng/ml, 51.6 ± 93.6 pg/ml, 10.0 ± 34.2 pg/ml and 22.3 ± 30.6 ng/ml, respectively. Obese patients had significantly higher mean values of resistin and PAI 1 than those who were overweight. These levels correlated significantly with anthropometric and biochemical variables; however, the correlations were weak. Age, menopause or the regular practice of physical activity had no effect on mean values. Conclusions: The group of women studied had altered inflammatory biomarkers in relation to people of normal weight. The study shows the inflammatory status of overweight/ obese individuals, and the values obtained may help to establish standard ranges for these markers.

    Full Text Available ABSTRACT: The study was conducted to know the prevalence of s oil-transmitted helminths (STH in children aged 1-14 years attending outpati ents and inpatients from both urban and rural background. Out of the 550 stool samples exami ned, 450 were from the study group and 100 from the control group. All the 450 children of the study group presented one or more of the classical symptoms like abdominal pain, low grade fever, diarrhoea, dysentery, constipation and pica. Hundred children from the control group did not have any classical symptoms. Thirty five per cent from the study group and 21 per cent fro m the control group were found positive for one or more of the helminthic infection. The prevalence of Ascaris lumbricoides, Trichuris tr ichiura, Ancylostoma duodenale & Necator americanus (hookworm, Hymenolepis nana and Enterobius vermicularis were 27%, 15%, 0.4%, 2% and 0.22%, respectively in the study g roup and 15%, 10%, 4%, 2%, and 2%, respectively in the control group. Strongyloides ster coralis was not found either in the study or control groups. Helminthic infections were more comm on in 7-9 years of age group, urban children with low socio-economic strata, and with m ale preponderance. Majority of children who harboured STH were suffering from abdominal pain and low grade fever. Total 450 clinical samples (control group examined b y direct wet mount, saturated salt floatation, and formalin-ether sedimentation; and o nly 391 samples examined by Kato-Katz semiquantitative techniques. Twenty six per cent posi tive by direct wet mount, 35% by both saturated salt floatation and formalin-ether sedime ntation whereas 38% of the samples were found positive by Kato-Katz semiquantitative techniq ue. In conclusion, concentration techniques like saturated salt floatation and forma lin-ether sedimentation are the best diagnostic tools to get authentic and reliable resu lts and to rule out fallacious inference caused by relying only on direct wet mount preparation, whe reas Kato-Katz, a semiquantitative technique is the best diagnostic method to know the prevalence and intensity of the STH infection. This technique is simple, rapid, reliable, and mild infections can also be detected. No special equipment and expertise are needed and it can be performed in the field survey.

    The ligaments are human tissues that are used in the transplantation area. A ligament is an anatomical structure in band form, composed by resistant fibers that connect the tissues that unite the bones with the articulations. In an articulation, the ligaments allow and facilitate the movement inside the natural anatomical directions, while it restricts those movements that are anatomically abnormal, impeding lesions that could arise of this type of movements. The kneecap ligament is a very important tissue in the knee mobility and of walking in the human beings. This ligament can injure it because of automobile accidents, for sport lesions or illnesses, and in many cases the only form of recovering the knee movement is carried out a transplant with the purpose of replacing the damage ligament by allo gen kneecap ligament processed in specialized Tissue Banks where the tissue is sterilized with gamma radiation of {sup 60}Co at very low temperatures, obtaining high quality ligaments for clinical application in injured patients. The kneecap ligaments are processed in the Tissue Banks with a segment of kneecap bone, a segment of tibial bone, the contained ligament between both bones and in some cases a fraction of the quadriceps tendon. In this work is given a description of the selection method of the tissue that includes the donor's serologic control, the kneecap ligament processing in the Radio Sterilized Tissues Bank, its sterilization with gamma radiation of {sup 60}Co, also it is indicated like the clinical application of the allo gen ligament was realized in a hasty patient and whose previous crossed ligament was injured. Finally the results are presented from the tissue obtaining until the clinical application of it is, and in this case is observed a favorable initial evolution of the transplantation patient.

    2014-01-01

    Full Text Available Background: Septic arthritis is an infrequent disease although very important due to the possibility of disastrous outcomes if treatment is not adequately established. Adequate information concerning the epidemiology of septic arthritis is still lacking due to the uncommon nature of the disease as well as the struggle to establish a correct case-definition. Objective: To epidemiologically characterize the population seen at Hospital das Clínicas, University of São Paulo with a diagnosis of septic arthritis between 2006 and 2011. Methods: Sixty-one patients diagnosed with septic arthritis of the knee between 2006 and 2011 were retrospectively evaluated. The patients' clinical and epidemiological characteristics, the microorganisms that caused the infection and the patients' treatment and evolution were analyzed. Results: Septic arthritis of the knee was more common among men, with distribution across a variety of age ranges. Most diagnoses were made through positive synovial fluid cultures. The most prevalent clinical comorbidities were systemic arterial hypertension and diabetes mellitus, and the most commonly reported joint disease was osteoarthritis. Staphylococcus aureus was the prevailing pathogen. Fever was present in 36% of the cases. All patients presented elevation in inflammatory tests. Gram staining was positive in only 50.8% of the synovial fluid samples analyzed. Six patients presented complications and unfavorable evolution of their condition. Conclusion: S. aureus is still the most common pathogen in acute knee infections in our environment. Gram staining, absence of fever and normal leukocyte count cannot be used to rule out septic arthritis.

    Fracture liaison services (FLS) aim to provide cost-effective targeting of secondary fracture prevention. It is proposed that a dedicated FLS be available in any hospital to which a patient presents with a fracture. An existing orthopaedic clinic nurse was retrained to deliver a FLS. Proformas were used so that different nurses could assume the fracture liaison nurse (FLN) role, as required. Screening consisted of fracture risk estimation, phlebotomy and DXA scanning. 124 (11%) of all patients attending the orthopaedic fracture clinic were reviewed in the FLS. Upper limb fractures accounted for the majority of fragility fractures screened n=69 (55.6%). Two-thirds of patients (n=69) had reduced bone mineral density (BMD). An evidence based approach to both non-pharmacological and pharmacotherapy was used and most patients (76.6%) receiving pharmacotherapy received an oral bisphosphonate (n=46). The FLS has proven to be an effective way of delivering secondary prevention for osteoporotic fracture in a non-regional fracture clinic, without increasing staff costs.

    Full Text Available Abstract Progress is being made in schizophrenia genomics, suggesting that this complex brain disorder involves rare, moderate to high-risk mutations and the cumulative impact of small genetic effects, coupled with environmental factors. The genetic heterogeneity underlying schizophrenia and the overlap with other neurodevelopmental disorders suggest that it will not continue to be viewed as a single disease. This has radical implications for clinical practice, as diagnosis and treatment will be guided by molecular etiology rather than clinical diagnostic criteria.

    Pompe disease (PD) is a rare autosomal recessive muscle lysosomal glycogenosis caused by a deficiency of acid-α-glucosidase. There are two main forms of the disease: aggressive infantile PD started within the first year of life with a severe enzyme deficiency and multiorgan involvement, and late onset PD (LOPD) with progressive signs and symptoms including predominant proximal, axial muscle weakness and respiratory insufficiency started at any time from 1 till 75 years and older. Usually due to physician's unawareness, most adults with PD are diagnosed with great delay. The typical features and early nonspecific signs in four patients, aged between 35 and 72 years, with confirmed LOPD are delineated and discussed in correspondence with the age of first signs, age development of muscle weakness, distribution and age of final diagnosis. The disorders for differential diagnosis and spectrum of conditions that expanded the possibility of PB are listed. The fluorometrically analyzed level of acid α-glucosidase from dried blood spots is considered to be the first choice diagnostic method for clinically suspected cases of LOPD.

    Multidetector computed tomography (MDCT) has started its implementation in cardiology with calcium quantification of coronary plaques in the study without contrast, using the calcium score, demonstrating an important independent predictor of future cardiac events. The examination with intravenous contrast, coronary angiography, appeared later as a noninvasive method for evaluation of anatomy and obstructive coronary disease, characterizing the degree of stenosis and the presence of non calcified atherosclerotic plaques, assessing not only the lumen, but also the vessel wall. With the advent of new machines with more detectors and higher temporal resolution has been a reduction in radiation dose and the possibility of new applications. (author)

    Full Text Available La Hidroxiapatita Porosa Coralina HAP-200 es un biomaterial de implante óseo desarrollado en Cuba hace más de 15 años y se ha aplicado con éxito como sustituto del injerto óseo y como implante ocular integrado. En el presente trabajo se brinda una información resumida de los principales resultados obtenidos en la etapa de desarrollo y aplicaciones clínicas del mismo. Este biomaterial en forma de bloques y esferas con diferentes dimensiones así como granulados con distintos tamaños de las partículas ha sido evaluado teniendo en cuenta todos los parámetros de su comportamiento "in vivo" tanto preclínico como clínico según exigen las normas de evaluación y registro de biomateriales del CCEEM del MINSAP de Cuba. Se han realizado varios protocolos de ensayos clínicos, tanto controlados como multicéntricos, de postproducción, de seguimiento y estudio del comportamiento clínico a largo plazo, de extensión e introducción en el sistema nacional de salud así como los estudios y diseño del sistema productivo y de gestión de la calidad que avalan la obtención de varios certificados de registro sanitario tanto en Cuba como en el extranjero así como los certificados de buenas prácticas de fabricación. Durante los 15 años de aplicaciones clínicas en Cuba se han tratado 9 613 pacientes en las especialidades de estomatología, incluyendo la cirugía maxilofacial, 783 personas han recibido implantes oculares y 2 592 han sido tratadas por defectos óseos de los huesos largos y otros en ortopedia y traumatología. Solo se ha reportado un 3,2 % de fracaso de los implantes por diferentes causas asociadas al tratamiento quirúrgico y en ningún caso por causa del biomaterial, demostrando este último una excelente biocompatibilidad con integración e incorporación a la dinámica natural del tejido óseo al cabo del tiempo. Los resultados obtenidos son excelentes tanto desde el punto de vista de las características y propiedades del biomaterial como de su comportamiento ¿in vivo¿ y el impacto en la salud y calidad de vida de nuestra población.

    Introduccion. El sindrome de Wolf-Hirschhorn (SWH) es una cromosomopatia producida por una delecion en la region distal del brazo corto del cromosoma 4. Se caracteriza por la presencia de un fenotipo peculiar, retraso en el crecimiento, retraso del desarrollo psicomotor y epilepsia. Objetivos. Describir las caracteristicas de una serie de niños con SWH, incluido el tiempo medio empleado para el diagnostico, y valorar la opinion de las familias sobre el proceso diagnostico. Pacientes y metodos. Se contacto con la Asociacion Nacional de SWH y, a traves de ella, con 29 familias afectadas. Se recogio informacion sobre la clinica del niño y la opinion sobre el proceso diagnostico, y se solicitaron informes medicos que confirmaran la informacion facilitada. Constituida una base de datos de pacientes, se procedio a su analisis estadistico. Resultados. Se obtuvo informacion de 27 familias. Los pacientes presentan una edad media actual de 6,94 ± 6,37 años. La edad media de diagnostico fue de 14,34 meses. Existe retraso del crecimiento intrauterino en el 92,6% de los embarazos. Un 92,6% de los pacientes presenta epilepsia, el 44,4% de ellos en monoterapia. Existe retraso del desarrollo psicomotor/cognitivo en todos los pacientes. Camina sin ayuda el 33%. Los padres califican con una nota media de 7,25 ± 2,17 el trato ofrecido por los facultativos y de 6,29 ± 2,11 la informacion recibida. Conclusiones. No se han encontrado referencias a la edad media de diagnostico para el SWH. En nuestra muestra, existen variaciones importantes en este aspecto, posiblemente condicionadas por el fenotipo del caso y la experiencia del medico. Las caracteristicas clinicas son similares a las esperadas. El grado de dependencia estimado es alto y la calidad de la informacion recibida por la familia, baja.

    Introduccion. La migraña es un trastorno muy comun, con incidencia en aumento. La teoria evolutiva permite explicar su aparicion, dadas las ventajas que aportaba a grupos originarios de Homo sapiens una mayor reactividad a estimulos, y la presencia creciente de interaccion con factores ambientales. Analizamos estos aspectos a traves de los mecanismos potenciales que los explican. Desarrollo. El diseño de los organismos y sus respuestas ambientales surgen para mejorar la supervivencia. Asi, el dolor y la cefalea pueden entenderse como respuestas homeostaticas y adaptativas. Menos del 10% de la poblacion no tiene experiencia de cefalea, y el fenotipo migrañoso es una repuesta dolorosa comun en formas secundarias y sindromicas de cefalea. Estas caracteristicas se entienden segun rasgos neurofisiologicos especificos (falta de habituacion, sensibilizacion y baja preactivacion), caracteristicas geneticas (trastorno poligenico con multiples genes de baja penetrancia, que interaccionan con el ambiente y que son comunes a los de los trastornos comorbidos, como depresion-ansiedad) e interaccion ambiental en las sociedades modernas (aumento del numero de ciclos estrogenicos, y especialmente sobreexposicion al estres). Conclusiones. Lo que fue una ventaja evolutiva se ha transformado en la sociedad moderna en un trastorno muy prevalente y frecuentemente incapacitante. Es el resultado de una interaccion con sobrecarga de estimulos externos (estres) e internos (hormonales), lo que, de acuerdo con la teoria evolutiva, convertiria a la migraña en una enfermedad por desajuste. Los efectos ocurririan precozmente, en la infancia, a traves de mecanismos de epigenetica. Se obtendria un gran beneficio terapeutico mediante intervenciones poblacionales y educativas que incorporen estos aspectos.

    Introduccion. Aunque las fistulas espinales suponen el 70% de las malformaciones arteriovenosas espinales, son una entidad infradiagnosticada. El shunt arteriovenoso produce una congestion vascular que da lugar a una mielopatia progresiva, en ocasiones irreversible si no se trata de forma precoz. Objetivo. Describir las caracteristicas clinicorradiologicas de una serie de pacientes con fistula espinal. Pacientes y metodos. Se realizo una busqueda retrospectiva de pacientes con diagnostico de fistula espinal ingresados en el area de neurociencias de un hospital de tercer nivel asistencial. Resultados. Se identificaron 19 pacientes (7 mujeres y 12 varones) con una edad media de 56 años. La fistula espinal fue de tipo I en un 79% de los pacientes y la localizacion dorsal fue la mas frecuente. La mayoria de los casos presento un curso progresivo (90%). Un 74% de los pacientes se diagnostico mediante resonancia magnetica. En cuatro casos fue necesaria la realizacion de una angiografia para llegar al diagnostico, y en uno de ellos se preciso una biopsia intraoperatoria. Se realizaron tres punciones lumbares, en dos de las cuales se objetivo pleocitosis linfocitaria e hiperproteinorraquia. El retraso diagnostico medio fue de nueve meses. Se trato a un 79% de los pacientes, y de ellos solo mejoro el 10%. Conclusiones. Ante una clinica sugestiva de fistula espinal, debe realizarse una angiografia espinal diagnostica aunque el paciente estudiado pueda presentar caracteristicas licuorales atipicas y normalidad en la resonancia magnetica medular.

    Introduccion. El mosaicismo diploide/triploide es una alteracion cromosomica poco frecuente. La produce un fallo en la division poscigotica durante el desarrollo embrionario. Da lugar a la coexistencia de dos lineas celulares con diferente constitucion cromosomica (46,XX y 69,XXX) en un mismo individuo. Su fenotipo clinico es caracteristico. Las alteraciones pigmentarias con un patron de distribucion que sigue las lineas de Blaschko son el principal signo guia, asi como las alteraciones de otros tejidos derivados del ectodermo. Casos clinicos. Describimos las caracteristicas clinicas de tres pacientes afectos de mosaicismo diploide/triploide y realizamos una comparacion de su fenotipo clinico con el de los casos publicados previamente en la bibliografia. Las alteraciones observadas con mayor frecuencia fueron alteraciones cutaneas, discapacidad intelectual, obesidad troncular, talla baja, hemihipertrofia, y manos pequeñas y estrechas con clino y camptodactilia. Las caracteristicas fenotipicas de nuestros pacientes fueron similares a las de los casos comunicados previamente. Aunque no existe un fenotipo unico y especifico asociado al mosaicismo diploide/triploide, existen malformaciones caracteristicas que conforman un sindrome malformativo bien definido. El cariotipo realizado en linfocitos de sangre periferica en las tres pacientes fue normal, y se logro el diagnostico mediante cariotipo en fibroblastos cultivados tras biopsia de piel hipopigmentada. Conclusiones. La presencia de discapacidad intelectual asociada a obesidad troncular, talla baja, hemihipertrofia o clino y camptodactilia, ademas de las alteraciones cutaneas, debe hacer pensar en la posible existencia de un mosaicismo diploide/triploide. En la mayoria de los casos, es necesario el estudio del cariotipo en los fibroblastos para llegar al diagnostico.

    Introduccion. La Iowa Rating Scale for Personality Change (IRSPC) presenta una serie de caracteristicas (enfasis en las funciones motivacionales y emocionales, evaluacion de las funciones ejecutivas 'cognitivas' en la vida cotidiana, estimacion de la personalidad premorbida, valoracion de la fiabilidad del informador) que hacen muy interesante su utilizacion tanto en la clinica como en la investigacion. Objetivo. Validar en castellano la IRSPC para la evaluacion de los 'cambios de personalidad' secundarios a las lesiones cerebrales de la corteza prefrontal en general y del area ventromedial en particular. Pacientes y metodos. Tras el proceso de traduccion y adaptacion de la guia de la escala al castellano, se realizo un estudio de validacion con 31 pacientes con daño cerebral traumatico y se obtuvieron unos resultados de fiabilidad muy adecuados. Resultados. Los resultados obtenidos al medir la consistencia interna de la IRSPC y los coeficientes de fiabilidad interobservadores y test-retest apoyan dicha afirmacion. La validez del instrumento es confirmada por la validez concurrente (comparandolo con el inventario neuropsiquiatrico) y la validez de constructo (comparando las puntuaciones de los pacientes antes y despues del traumatismo). Conclusiones. La IRSPC es un instrumento fiable y valido para la exploracion clinica, en el contexto de una evaluacion integral de los sintomas derivados de las enfermedades neurologicas en general, y en particular de aquellas en las que se encuentra involucrada la corteza prefrontal ventromedial.

    Introduccion. Las diferencias de sexo y el caracter (rural o urbano) de las poblaciones determinan en gran medida el abordaje integral de patologias dependientes del tiempo, como el ictus, principal causa de hospitalizacion y mortalidad femenina en nuestro medio. Objetivo. Determinar si en un area sanitaria rural del Principado de Asturias se ponen de manifiesto las caracteristicas diferenciales entre mujeres y hombres con ictus. Pacientes y metodos. Estudio descriptivo retrospectivo realizado en el Hospital de Jarrio. Se revisaron variables a traves de las historias clinicas informatizadas de los pacientes que sufrieron ictus en 2013. Resultados. Se produjeron 126 altas totales, el 53,2% en las mujeres, que sufrieron la enfermedad con un retraso de cinco años (p mujeres, que recibieron un tratamiento principalmente conservador con mayor hidratacion parenteral (p < 0,017) y reposo. El grupo femenino sufrio mas complicaciones, discapacidad al alta (p < 0,001) y a los tres meses (p < 0,004), y registro porcentajes mas elevados de institucionalizacion posterior (p < 0,005). Conclusiones. Existen diferencias de sexo demograficas, en el perfil de riesgo cerebrovascular, la presentacion clinica, el manejo hospitalario y la comorbilidad del ictus en esta poblacion rural, que sugieren areas de mejora.

    2013-09-01

    Introduccion. Las miopatias congenitas son un grupo heterogeneo de enfermedades que comparten clinica de inicio precoz y alteraciones histopatologicas musculares especificas. El estudio genetico permite determinar la mutacion causal en la mayoria de los casos. Existe heterogeneidad fenotipica y genotipica, lo que se ilustra al observar que un genotipo puede expresarse en mas de una forma clinicopatologica y un fenotipo puede estar causado por diferentes mutaciones geneticas. Desarrollo. En esta revision, se detallan las caracteristicas de las principales miopatias congenitas que permiten su identificacion clinica, patologica y genetica. Se describen los hallazgos de la biopsia muscular que constituyen el principal pilar diagnostico. Se enfatiza y se detalla la importancia del diagnostico diferencial, descartando otras patologias que se presentan con hipotonia en la lactancia o el periodo neonatal. Se destacan las formas neonatales graves (nemalinica, miotubular ligada al X) que se deben identificar precozmente para establecer el pronostico y brindar un consejo genetico adecuado. Se subrayan las mutaciones del gen rianodina (RYR1) por su asociacion a la hipertermia maligna y las mutaciones de la selenoproteina 1 (SEPN1) y la miopatia nemalinica por su asociacion a hipoventilacion nocturna. Conclusiones. El conocimiento profundo de las miopatias estructurales congenitas facilita la confirmacion diagnostica de la miopatia congenita, lo que permite la aplicacion oportuna de medidas relacionadas con la respiracion y la alimentacion de los casos mas graves y con la optimizacion de la funcion motora en todos los pacientes con miopatia congenita.

    Introduccion. En la edad pediatrica, la forma mas frecuente de neuritis optica se presenta generalmente despues de un cuadro infeccioso, con edema de papila, que suele ser bilateral y tiene buen pronostico. La conversion a esclerosis multiple es infrecuente. Objetivo. Presentar las caracteristicas clinicas y de laboratorio de una serie pediatrica de neuritis optica. Pacientes y metodos. Se analiza una serie de 17 casos de neuritis optica en niños y jovenes de 4 a 14 años, referidos entre los años 2000 y 2015. Resultados. La edad mediana de la serie fue de 11 años. Predominaron los pacientes de sexo femenino y el antecedente infeccioso fue poco frecuente; en cinco pacientes, la afectacion fue bilateral, y cuatro casos se presentaron como neuritis optica retrobulbar. La resonancia magnetica mostro hiperintensidad en T2 en los nervios opticos afectados en cinco pacientes. El estudio del liquido cefalorraquideo y bandas oligoclonales fue normal en todos los casos. Los pacientes, tratados con metilprednisolona intravenosa, tuvieron buena recuperacion. Solo en tres casos se comprobo una evolucion posterior a esclerosis multiple. Conclusiones. En esta serie, los casos que evolucionaron a esclerosis multiple no mostraron diferencias clinicas, aunque si presentaron mayor cantidad de lesiones hiperintensas en la resonancia magnetica. Este hecho, descrito en trabajos previos, apoya nuestro esquema diagnostico y terapeutico en un intento por acercarnos al manejo optimo de esta patologia.

    2016-05-01

    Introduccion. La enfermedad de Pelizaeus-Merzbacher es un trastorno hipomielinizante raro debido a alteraciones en el gen PLP1, que lleva a un fallo de la mielinizacion axonal de los oligodendrocitos en el sistema nervioso central. Existen dos formas descritas segun la gravedad de su presentacion: connatal y clasica. Se caracteriza por hipotonia neonatal, retraso del desarrollo psicomotor, espasticidad progresiva de predominio en los miembros inferiores y nistagmo, con signos y sintomas piramidales y extrapiramidales, y la forma connatal es mucho mas grave. La resonancia magnetica muestra leucoencefalopatia hipomielinizante difusa, los potenciales evocados usualmente se alteran y la confirmacion se realiza mediante estudio molecular del gen PLP1. Casos clinicos. Se presentan cinco pacientes pediatricos afectados, cuatro con la forma clasica y uno con la forma connatal; se describen las caracteristicas clinicas, los estudios complementarios y se realiza una revision concisa de la bibliografia. Conclusion. Esta enfermedad tiene una evolucion progresiva y casi invariable, lo cual es la clave clinica para diferenciarla de otras entidades como la paralisis cerebral infantil, neuropatias perifericas, esclerosis multiple, entre otras, ademas de los hallazgos caracteristicos en las neuroimagenes. Es necesario sospechar este diagnostico y confirmar alteraciones en el gen PLP1 con el fin de obtener una incidencia real de esta entidad, probablemente subestimada, como otras leucodistrofias.

    Jalda, D; Junco, A; Alvarez-Moreno, M; Rodero, I; Carneado-Ruiz, J

    2016-07-01

    Introduccion. El botulismo es un sindrome causado por la toxina del bacilo Clostridium botulinum. La toxina actua bloqueando las terminaciones colinergicas presinapticas de la placa motora y del sistema nervioso parasimpatico, y ocasiona una paralisis flacida y un fallo parasimpatico. El modo mas habitual de adquisicion de la enfermedad es por ingesta de toxina preformada presente en las conservas caseras mal esterilizadas, aunque otros mecanismos son posibles. Su incidencia actual en Espana es muy baja. Casos clinicos. Se describen tres miembros convivientes de una familia que presentaron un cuadro de botulismo alimentario. Las manifestaciones clinicas iniciales mostraron predileccion por la paresia ocular y por sintomatologia disautonomica de escasa especificidad, y la agregacion familiar fue el indicio fundamental que sugirio el diagnostico. Posteriormente, los pacientes empeoraron y dos de ellos presentaron afectacion de la funcion respiratoria y precisaron ingreso prolongado en la unidad de cuidados intensivos. Los tres pacientes convalecieron y se recuperaron sin secuelas. Se consiguio detectar la toxina botulinica por bioensayo en los restos de alimentos, lo que confiere al caso la categoria diagnostica de confirmado. Conclusiones. La microepidemia familiar presentada constituye un caso de afectacion inicial predominantemente ocular y disautonomica. Asimismo, ilustra varios aspectos tipicos de la enfermedad: la sospecha diagnostica ante pacientes convivientes que acuden simultaneamente por clinica similar, las complicaciones caracteristicas del proceso y su tratamiento, el diagnostico de laboratorio y su historia natural hacia la resolucion.

    Introduccion. Las encefalitis viricas son procesos raros y potencialmente graves, con etiologia diversa y no siempre identificable. El objetivo es describir las caracteristicas etiologicas, la presentacion clinica y la evolucion neurologica de las encefalitis viricas que ingresaron en las unidades de cuidados intensivos pediatricos (UCIP) en España. Pacientes y metodos. Estudio prospectivo multicentrico observacional. Se incluyeron los niños ingresados en 14 UCIP con diagnostico de encefalitis virica durante un periodo de tres años (2010-2013). Para el diagnostico etiologico se utilizo reaccion en cadena de la polimerasa y serologia a virus neurotropos en la sangre y el liquido cefalorraquideo. Se registraron los antecedentes personales, la presentacion clinica, la evolucion y la situacion neurologica en el momento del alta. Resultados. Se incluyeron 80 pacientes con edad media de 5 años; el 70%, varones. Los sintomas clinicos mas relevantes fueron disminucion de conciencia (86%), fiebre (82,4%), convulsiones (67%), vomitos (42%), cefalea (27%), agitacion (25%) y desorientacion (23%). Se llego al diagnostico etiologico en un 35%, y los mas frecuentes fueron virus herpes simple y enterovirus. La evolucion fue curacion sin secuelas en 55 pacientes (69%, sobre todo enterovirus, rotavirus y virus respiratorios), secuelas leves-moderadas en 19 (23,5%) y graves en seis (7,5%). Dos pacientes fallecieron. Conclusiones. En las UCIP españolas solo se realizo el diagnostico etiologico en un tercio de los niños con sospecha de encefalitis virica grave. A pesar de la gravedad clinica, hemos observado una tasa de mortalidad y morbilidad baja. La amplia mayoria son dados de alta de la UCIP con ninguna o escasa secuela neurologica.

    The Alto Paraguay Province is located at the border of the State of Mato Grosso do Sul and Paraguay, between the coordinates 21 deg 10{sup `}to 23 deg 25{sup `}of Southern latitude and 57 deg 10{sup `} to 58 deg 00{sup `}, having the city of Porto Murtinho as the main reference point. The geotectonic domain of the area is governed by the precambric units of the Southern extreme of the Amazonic craton which developed a long and accentuated activity, giving rise to folds and important faults, that in several cases seem to have exerted an effective control of the magmatic manifestations. Radiometric data indicate that the emplacement of the syenitic bodies took place in the Permo-Triassic period, with a major incidence in the interval 260-240 Ma, representing thus, an important phase of alkaline magmatic affinity associated to the Parana Basin which is believed is to be unique, since the other known areas (Central, Amambay and Rio Apa Provinces, Paraguay, Velasco Province, Bolivia) are considerably younger (140-120 Ma). Syenitic rocks from the Alto Paraguay Province show wide variation in the ratio {sup 87} Sr/{sup 86} Sr (0.703361 - 0.707734). Excluding the Cerro Boggiani rocks (0.703837-0.707734), values for the nepheline syenites (0.703361-0.703672) general lower than those of the other syenites types. Alkaline syenites cover the interval 0.703510- 0.703872, while quartz syenites and syenogranites are 0.704562 and 0.707076, respectively. geologic evidence, in addition to petrographic, geochemical and isotopic (Sr) data, suggest that the syenitic rocks have been derived from an unique mantelic parental liquid, by fractional crystallization and assimilation processes, which are assumed to be occurred during the emplacement of the magma in the crust.

    The sugar cane processing wastes (bagasse and trash) became an important energy source which may be used in the electrical energy co-generation. This work is aimed to determine the trash physical properties, define its energetic value and ideal combination of bagasse + trash to use in conventional boilers. The trash productivity (20 t/ha), green (14.9%) and dry (71.3%) leaves, and remaining material (8.3%) was found one day after the cane crop. The trash moisture content was measured for each component and the final average value was 28.7%. The bagasse showed a 49.81% moisture average content. The higher heating value (HHV) was found for the bagasse (19.27 MJ/kg), trash (17.90 MJ/kg) and bagasse + trash mixtures in different proportions. For the lower heating value (LHV), we observed that the released energy in the trash (12.11 MJ/kg) was higher than the one in the bagasse (8.55 MJ/kg). This result was expected due to the higher bagasse moisture content. From the analysed mixtures, the 50%-50% one had the highest LHV (10.08 MJ/kg), showing that the trash left in the field after the crop may be efficient for the energy production mixed to the bagasse in 50% proportion.

    Iron is one of the most common heavy metals found in gasoline. Its source may be, the crude oil itself, fuel additives or contamination. Heavy metals are known to catalyze oxidation reactions of several gasoline components and, therefore, may have an effect on some of gasoline quality parameters, such as gum formation, distillation curve and octane number. This study is concerned with an evaluation of the influence of copper on these parameters, and involved iron concentrations of up to 1.8 mg/L. The results have shown that that level of contamination does not affect the octane number and the distillation curve of gasoline. However, there is a sharp increase in gum formation, even at very low iron concentrations. (author)

  15. Inversor Resonante de Tres Elementos L-LC con Caracteristica Cortocircuitable para Aplicaciones de Calentamiento por Induccion

    Science.gov (United States)

    Espi Huerta, Jose Miguel

    Los generadores de calentamiento por induccion son puentes inversores con carga resonante, cuya mision es basicamente crear una corriente sinusoidal de gran amplitud sobre la "bobina de caldeo", que forma parte del tanque resonante. En el interior de esta bobina se introduce la pieza que se desea calentar. EI campo magnetico creado induce corrientes superficiales (corrientes de Foucault) sobre la pieza, que producen su calentamiento. Los tanques resonantes (tambien llamados osciladores) utilizados en la actualidad son el resonante serie y el resonante paralelo. Aunque ya desde hace algun tiempo se vienen construyendo generadores de alta potencia basados en estos dos osciladores, el exito nunca ha. sido completo en ninguno de los dos casos. Tal y como se explica en la introduccion de esta memoria, los puentes inversores utilizados deben operar sobre una carga inductiva (corriente retrasada) para evitar el fenomeno de la recuperacion inversa de sus diodos y la consiguiente ruptura de los transistores. De la restriccion topologica anterior se deduce que el generador paralelo debe conmutar a frecuencias inferiores a la resonancia, y el serie a frecuencias superiores. A esta restriccion topologica hay que unir otra que es exclusiva del calentamiento por induccion: La corriente por la bobina de caldeo debe ser sinusoidal. De no ser asi, resultaria imposible disponer toda la potencia de calentamiento sobre la pieza en el espesor requerido por la aplicacion. Como consecuencia, los inversores no pueden operar por debajo de la frecuencia de resonancia del oscilador, pues en ese caso se amplifican los armonicos de orden superior de la tension/corriente de entrada situados sobre la resonancia, con la consiguiente distorsion de la corriente de salida. La conjuncion de las dos restricciones anteriores obligan al inversor paralelo a funcionar a la frecuencia de resonancia del oscilador. Esto imposibilita un control por variacion de frecuencia, regulandose la potencia desde la seccion de entrada mediante un mayor o menor aporte de corriente al puente. Como consecuencia, la seccion de entrada del paralelo, ya de por si mas voluminosa que lao del serie por el uso de grandes componentes magneticos (bobinas de filtro o de "alisamiento"), result a tambien mas complicada y costosa debido a la necesidad de ser implementada mediante rectificador controlado. Ademas, la regulacion que ofrece el rectificador es pobre, dada su baja frecuencia de conmutacion. En cambio, el circuito serie puede funcionar por encima de la resonancia manteniendo una secuencia de conmutacion sin riesgos de recuperacion inversa y con una corriente de salida practicamente sinusoidal, lo que permite un control de la potencia por variacion de frecuencia. Puesto que la tarea de regulacion se realiza desde el puente inversor, la regulacion resulta mucho mas eficaz y la seccion de entrada se puede implementar mediante un simple rectificador no controlado y un condensador de filtro.

    It was prepared zirconium oxide, ZrO{sub 2}, by means of hydrolysis-condensation reactions (sol-gel method), using zirconium propoxide, Zr(C{sub 3}H{sub 7}O){sub 4}, as precursor and nitric acid, HNO{sub 3}, as catalyst of the hydrolysis reaction. In this synthesis it was used a molar ratio water-alkoxide, r=n{sub H2O}/n{sub Zr}(C{sub 3}H{sub 7}0){sub 4}, high, similar to 200, so that the hydrolysis happens quickly and the nucleation and growth are completed in very little time. The solid was characterized with Ftir spectrophotometry, Differential thermal analysis (Dta), Thermal gravimetric analysis (T G), X-ray diffraction of powders, Scanning electron microscopy (Sem) and X-ray Dispersion energy (EDX). The ZrO{sub 2} obtained by this way is amorphous even to 300 C and it consists of big aggregates. The amorphous ZrO{sub 2}, presents thermoluminescent behavior, after it was irradiated with UV radiation and beta particles of {sup 90}Sr/{sup 90}Y and it was thermally stimulated. (Author)

    It was determined the lineal attenuation coefficient of hepatic tissue before gamma radiation of a source of {sup 137} Cs. When exposing organic material before X or gamma radiation fields, part of the energy of the photons is absorbed by the material, while another part crosses it without producing any effect. The quantity of energy that is absorbed is a measure of the dose that receives the material. The three main mechanisms by means of which the gamma rays interacting with the matter are: The Photoelectric Effect, the Compton dispersion and the Even production; the sum of these three processes is translated in the attenuation coefficient of the radiation. In this work we have used hepatic tissue of bovine, as substitute of the human hepatic tissue, and we have measured the lineal attenuation coefficient for photons of 0.662 MeV. Through a series of calculations we have determined the lineal attenuation coefficient for photons from 10{sup -3} to 10{sup -5} MeV and the measured coefficient was compared with the one calculated.

    Radiological Images of kidneys stones were analyzed, quantifying the optical density (D.O.) and the blackening degree in the radiographic film of the samples. Studies of the literature, analyses of samples and interviews with specialists of the Center of Sciences and Technologies of Materials (CCTM) of the Institute of Energy and Nuclear Researches (IPEN/CNEN-SP), after crystallographic analysis for absorption techniques and diffraction of ray-X, showed that D.O. of the stones it is more directly dependent of their dimensions of what of their contents concentration. It is the researchers' consensus that as larger D.O. of the radiographic image of the calculation renal, larger her density (g/cm{sup 3}) and therefore larger the importance of the application of an appropriate energy for the fragmentation of the calculation. This energy, supplied by the equipment extracorporeal shock wave lithotripsy (ESWL) it depends on several parameters inside the ones which the anatomy and the patient's position and of the own limitations of the lithotripsy equipment. This interpretation, at least for the analyzed samples, it disappoints a simplistic correlation among the parameters of the shock waves used in the lithotripsy procedures and the measures of D.O. and characteristics minerals. Another restriction factor is the discrepancy of the radiological image the kidneys stones camped in the patient, surrounded by the organs and interposed bone structures, and gotten her through the analysis of the fragments expelled after the accomplishment of ESWL, which present great variety of granulations.

    This work presents a calculational methodology for dose determination in human eye structures, such as: sclera, choroid, retina, lens, vitreous body, optic nerve and disc, and cornea, as well as tumor due to treatment to the eye plaques. A human eye model was constructed taking into consideration its main structural and dimension characteristics. Beyond that a mathematical model for the Co-60 and 1-125 plaques with all geometric details were built employing the MCNP-4C code. This model is able to calculate the axial and radial doses in any point of the eye and for each of its structures. An acrylic eye simulator was also built with the aim to obtain experimental results for the both model validations. This simulator is made of an acrylic sphere split into foils of 1 mm thickness which allow the introduction of a radiographic film to measure the axial and radial doses. The experimental data were used to validate the MCNP-4C results. The data from the mathematical model will serve as the basis to build a data bank for all the eye structures allowing different position and sizes of tumor as well as the replacement of all ophthalmic plaques used in the treatment. This data bank will be the principal part for the construction of a national software for the dose calculation and can be of great help for a reliable treatment system planning in radiotherapy/brachytherapy.

    Trapeziometacarpal osteoarthritis occurs mainly in women during the menopausal period. It is related to manual activities and is usually bilateral. The onset is insidious and the evolution is slow and progressive. It is characterized by of strength and pain in the basis of the thumb resulting in limitation of the use and function of the hand. The diagnosis of this condition is based on the physical examination. The manouver of compression axial-rotation of the trapezimetacarpal joint is a common positive finding. Typical findings of osteoarthritis are present in the radiological studies. Scintigraphic images have a predictive value. The early diagnosis is important to avoid the risk factors and to prevent disabilities of the hand. (author) 102 refs., 18 figs., 10 tabs.

Studiendesign: Dreizehn physisch aktive Patienten mit milder bis mittlerer EH wurden eingeschlossen: Alter: 43 ± 3 Jahre, Gewicht: 80 ± 2 kg, Blutdruck (BP: 151 ± 3/101 ± 3 mmHg, Herzfrequenz: 72 ± 3/Min. Nach einer 14-tägigen Wash-out-Periode wurde eine Spiroergometrie bis zur maximalen Erschöpfung (WHO-Schema durchgeführt, gefolgt von einer 60-minütigen submaximalen fahrradergometrischen Belastung auf der 2 mmol/l Laktat-Schwelle 48 h später. Vor, während und direkt nach den Belastungen wurden Blutproben entnommen. Das gleiche Protokoll wurde nach einer 42-tägigen Behandlungsphase mit 5 mg Amlodipin o.d. wiederholt. Ergebnisse: Die Amlodipintherapie führte zu einer signifikanten Senkung des systolischen und diastolischen Blutdrucks in Ruhe und während maximaler und submaximaler Belastung. LDL- und HDL-Cholesterin, Glukose, freie Fettsäuren, Plasma-Insulin, Cortisol und der belastungsinduzierte Anstieg von Beta-Endorphinen und hGH blieben unverändert. Maximale Herzfrequenz, Maximalleistung und Ausdauerleistungsfähigkeit, maximale Sauerstoffaufnahme wurden durch die Amlodipintherapie nicht beeinflußt. Das Druck-Frequenz-Produkt (PFP wurde durch Amlodipin signifikant verringert. Diskussion: Amlodipin kontrolliert den Blutdruck effektiv in Ruhe, während der Maximalbelastung und während der submaximalen Belastung, denen der körperlich aktive Patient, häufig ausgesetzt ist. Die Abnahme des PFP weist auf einen reduzierten myokardialen Sauerstoffbedarf hin. Die Stoffwechselneutralität und die Neutralität hinsichtlich der bei Belastung anfallenden Streßhormone sowie die Beibehaltung der Leistungsfähigkeit im maximalen und submaximalen Bereich zeigen die Eignung von Amlodipin in der Therapie bei körperlich aktiven Patienten mit arterieller Hypertonie und lassen bei zudem erhaltener subjektiver Leistungsbereitschaft auf eine gute Compliance hoffen.

El presente trabajo explora dos cuestiones relacionadas con la aparicion de quejas subjetivas de memoria en adultos jovenes: la posibilidad de que dichas quejas sean resultado de deficits atencionales y ejecutivos, y, por otro lado, si determinadas caracteristicas de la personalidad propician y modulan la expresion clinica de las quejas. Sujetos y metodos. Se administro el Memory Everyday Failures, version española, el inventario de sintomas prefrontales y el inventario del temperamento y el caracter-revisado a una muestra de 1.132 participantes (900 de poblacion general y 232 en tratamiento por adiccion a drogas). Se exploro la correlacion entre variables de las quejas de memoria, del funcionamiento prefrontal en la vida diaria y de las dimensiones de la personalidad propuestas por Cloninger. Se estudiaron relaciones de causalidad entre las variables mediante metodos estructurales. Resultados. Se observa una fuerte correlacion entre las quejas cognitivas y la sintomatologia prefrontal, lo que sugiere que las quejas son, en realidad, resultado de una inadecuada gestion atencional y ejecutiva que propicia los errores cotidianos. Se aprecia tambien una relacion con gran tamaño del efecto entre las quejas cognitivas y la baja autodireccion. Esta dimension de la personalidad presenta una importante capacidad predictiva sobre la aparicion y la intensidad de las quejas, bien directamente, bien modulada por otras dimensiones, especialmente la evitacion del daño. Conclusiones. Los datos apoyan la idea de que las quejas de memoria son producto de la autopercepcion de fallos y errores cotidianos provocados a nivel atencional y ejecutivo –aunque son tenidos por olvidos mnesicos–, y que la expresion clinica de dichas quejas esta modulada por un perfil de la personalidad.

    Introduccion. La enfermedad de Charcot-Marie-Tooth (CMT) es una neuropatia que afecta los nervios motores y sensitivos, y la CMT1A es el subtipo mas frecuente en el mundo. La CMT1A se produce por una duplicacion de 1,5 Mb en el locus 17p11.2-p12, donde se localiza el gen PMP22. Para el diagnostico de CMT1A es importante contar con tecnicas moleculares especificas para la determinacion de esta mutacion. Objetivos. Establecer un metodo de uso rutinario para detectar la duplicacion de PMP22 en la poblacion mexicana y estimar su frecuencia en pacientes con caracteristicas clinicas para la CMT. Pacientes y metodos. Se analizaron 157 pacientes mexicanos no relacionados entre si, diagnosticados de CMT por valoracion clinica. La determinacion de la duplicacion de PMP22 se realizo a traves de reaccion en cadena de la polimerasa en tiempo real mediante el metodo comparativo 2–ΔΔCT. Resultados. El metodo 2–ΔΔCT para detectar la duplicacion del gen PMP22 mostro ser sensible y fiable. Los resultados fueron consistentes con los obtenidos mediante la tecnica de hibridacion in situ fluorescente. Se detecto la duplicacion de PMP22 en 79 pacientes (50,3%), con un comportamiento similar a lo comunicado en Estados Unidos, Australia, Finlandia, Suecia y España. Sin embargo, se observo que existen diferencias con otras poblaciones. Conclusiones. La tecnica de reaccion en cadena de la polimerasa cuantitativa se implemento como un diagnostico molecular de CMT1A eficaz y de bajo coste, por lo que puede utilizarse rutinariamente en Mexico. Esto es esencial para el asesoramiento genetico y el tratamiento oportuno de los pacientes con CMT. La frecuencia de la duplicacion del gen PMP22 varia entre regiones geograficas, por lo que es importante estimarla en diferentes poblaciones.

    Full Text Available Meningiomas are uncommon tumors in children and either more rarely encountered in the pineal region. We report two cases of meningioma of the pineal region in children. One of these cases was a five years-old girl and the other a one year-old boy. No specific clinical presentation or tomographic examinations findings was identified before treatment, suggestive of a diagnosis of menigioma. The clinical and laboratory features were very similar to the most common tumors of the pineal region. Prior to the surgery, the histology of these tumors was not suspected. Both patients underwent direct surgery and complete removal was achieved by a suboccipital transtentorial approach. The tumors originated from velum interpositum in both cases. At the follow up, one case presented with recurrence six years later, and she underwent a reoperation with total resection without morbidity. Long-term follow up presented no other recurrences.Meningiomas são tumores poucos frequentes em crianças, e mais raramente encontrados na região da pineal. Relatamos dois casos de meningioma da região da pineal em crianças, uma menina de cinco anos e um menino de um ano de idade. Não foi identificada nenhuma forma de apresentação clinica ou caracteristica tomográfica, antes do tratamento, que sugerisse o diagnóstico de meningioma. As características clinicas e laboratoriais encontradas foram similares às de tumores mais frequentes da região da pineal. Ambos os pacientes foram submetidos ao tratamento cirúrgico e a remoção completa foi obtida por abordagem suboccipital transtentorial. Durante o seguimento, um dos pacientes foi reoperado por recorrencia do tumor seis anos após o tratamento inicial. Atualmente, os pacientes encontram-se livres de recorrência tumoral.

    Introduccion. La esclerosis multiple (EM) es una enfermedad inflamatoria desmielinizante del sistema nervioso central con patogenia inmunomediada. Recientes estudios indican un aumento de su prevalencia, y numerosos trabajos relacionan el virus de Epstein-Barr (VEB) con su etiologia. Objetivo. Analisis de prevalencia de la EM en la Region de Murcia, incluyendo la descripcion de las caracteristicas clinicas en el momento del inicio de la enfermedad, y del estado serologico del VEB de los pacientes con EM. Pacientes y metodos. Estudio epidemiologico retrospectivo, tomando como muestra la poblacion residente en el area sanitaria centro-oeste de la Region de Murcia (257.865 habitantes). Se analizan datos clinicos y serologicos extraidos de diferentes fuentes. Resultados. Prevalencia de la EM en la poblacion estudiada: 88 casos/100.000 habitantes. Prevalencia de la EM junto con el sindrome desmielinizante aislado: 98,4 casos/100.000 habitantes. Incidencia media de la EM: 5,8 casos/100.000 habitantes/año. En el inicio de la EM, el 67,8% eran mujeres, el 81,9% presentaba un curso recurrente-remitente, la edad media era de 31,4 años, el sistema funcional mas frecuentemente afectado era el sensitivo (45,1%), el inicio fue monofocal en el 55,4% y el grado de discapacidad en la Expanded Disability Status Scale era de 2,1 puntos. La seroprevalencia del VEB fue del 99,3%. La reactivacion de la infeccion por VEB se relaciono con actividad clinica de EM en 10 pacientes (45,4%). Conclusiones. Actualmente, la prevalencia de la EM en la Region de Murcia es similar a la estimada en otras comunidades autonomas españolas. El estudio confirma la tendencia de incremento de prevalencia observada en las ultimas decadas.

    Introduccion. La arquitectura interna del hematoma subdural cronico (HSDC) es un factor muy importante que se debe tener en cuenta como predictor de recidiva. Objetivo. Analizar los factores posiblemente asociados a la recidiva de los HSDC, prestando especial atencion a dicha arquitectura. Pacientes y metodos. Hemos revisado 147 pacientes tratados desde 2010 hasta 2013. Dividimos los HSDC en cuatro tipos de acuerdo con la clasificacion de Nakaguchi de 2001. Ademas, hemos recogido diferentes caracteristicas clinicas y las hemos sometido a analisis estadistico para evaluar su posible asociacion con la tasa de recidiva de los HSDC. Resultados. La tasa de recidiva fue del 14,75% y la de mortalidad, del 4,76%. El tratamiento con anticoagulantes, el tipo de hematoma y el no usar drenaje subdural fueron factores de riesgo estadisticamente significativos para la recurrencia del HSDC. Segun la arquitectura interna, la tasa de recidiva fue del 36,36% para el tipo separado, del 15,90% para el laminar, del 8,82% para el homogeneo y del 0% para el trabecular. Dicha tasa fue significativamente mayor en el tipo separado respecto al homogeneo y trabecular. Conclusiones. El tratamiento con anticoagulantes y el no usar drenaje subdural son factores de riesgo de recurrencia de HSDC. Ademas, la division de los HSDC de acuerdo con la clasificacion de Nakaguchi puede ser util para predecir el riesgo de recurrencia, ya que la tasa de recidiva del tipo separado fue significativamente mayor que la del resto de tipos.

    Introducción: Los tratamientos antineoplasicos orales presentan ventajas en cuanto a coste, comodidad y mejora potencial en la calidad de vida respecto al tratamiento endovenoso, pero es mas dificil controlar la adherencia y monitorizar los efectos adversos. El objetivo de este estudio fue conocer la adherencia real en pacientes con antineoplasicos orales en nuestro centro, analizar la influencia de las caracteristicas del paciente y del tratamiento, identificar motivos de no adherencia, oportunidades de mejora en la atencion farmaceutica y evaluar la posible relacion adherencia y respuesta al tratamiento. Método: estudio prospectivo observacional de cuatro meses de duracion, en los pacientes con tratamiento antineoplasico oral dispensado desde la consulta de farmacia oncologica. Para la recogida de datos se utilizaron: orden medica, historia clinica y visita con entrevistas al paciente. Resultados: Se evaluaron un total de 141 pacientes. Un 72% se considero totalmente adherente, mientras que en un 28% se detecto algun tipo de no adherencia. El tiempo desde el diagnostico y la presencia de efectos adversos fueron las variables que afectaron a la adherencia. No se pudo demostrar relacion entre adherencia y respuesta al tratamiento. Conclusiones: La adherencia al tratamiento antineoplasico oral en nuestro centro fue del 72%, identificando oportunidades de mejora en la atencion farmaceutica dirigidas a prevenir los efectos adversos y a potenciar la adherencia de nuestros pacientes.

    2015-03-16

    Introduccion. La epidemia causada por el virus del Ebola en Africa occidental afecta a Guinea, Liberia, Sierra Leona, Nigeria, Mali y Senegal, y es la mas grave desde que se tiene noticia de este filovirus causante de fiebre hemorragica. En este articulo se revisan las caracteristicas epidemiologicas y las manifestaciones clinicas asociadas a la enfermedad por el virus del Ebola. Desarrollo. Hasta el 23 de febrero de 2015 se habian contabilizado 23.729 casos de ebola, con un 40,1% de mortalidad. En la actual epidemia, el virus se transmite al ser humano por tres vias: contacto con fluidos y secreciones de sujetos enfermos ya diagnosticados, contacto con cadaveres durante las ceremonias de enterramiento, y contagio a familiares y personal sanitario por enfermos sin diagnosticar. El Ebola causa una enfermedad grave en humanos. Tras un periodo de incubacion variable (2-21 dias), se inicia un sindrome febril, cefalea, mialgias, artralgias, vomitos y diarrea. La fase avanzada cursa con hemorragias, fracaso de multiples organos, hipotension y choque. Se desconoce la incidencia de manifestaciones neurologicas, aunque se han descrito hemorragias cerebrales y sindromes postinfecciosos en otras fiebres he­morragicas virales. Los cuidados de soporte son vitales. No existe un tratamiento efectivo demostrado, aunque varios pacientes han sido tratados con un coctel de anticuerpos monoclonales (ZMapp). Conclusiones. La identificacion y diagnostico precoz de casos sospechosos, el aislamiento de sujetos enfermos y las medidas de proteccion en el personal sanitario son fundamentales para contener esta epidemia.

    Introduccion. La cefalea como sintoma es una patologia frecuente y uno de los principales motivos de consulta por parte de atencion primaria. Objetivo. Analizar las caracteristicas de los pacientes derivados desde atencion primaria a la consulta de neurologia general con cefalea o neuralgia como motivo de consulta, y la concordancia diagnostica. Pacientes y metodos. Estudio descriptivo transversal de todos los pacientes remitidos desde atencion primaria; se recogieron variables demograficas/clinicas y se compararon las hipotesis diagnosticas de atencion primaria y neurologia, determinando su concordancia. Resultados. Se remitieron desde atencion primaria 2.514 pacientes (588 de ellos con caracter preferente); en 378 casos el motivo de la consulta fue cefalea o neuralgia (42,46 años de media; el 77,8%, mujeres). En 139 pacientes se establecio tan solo un diagnostico semiologico y en el resto predominaron la migraña episodica (49,79%), la cefalea tensional cronica (18,41%) y la neuralgia del trigemino (12,13%). Desde neurologia, los diagnosticos mas frecuentes fueron, respectivamente, 33,86%, 24,05% y 18,67%. Se obtuvo un coeficiente kappa de 0,543 (p cefaleas constituyen un motivo de consulta desde atencion primaria muy frecuente (15%). La concordancia diagnostica es moderada en nuestro sector sanitario, por lo que es necesario diseñar programas de formacion que ayuden a perfilar los criterios de derivacion al especialista y mejorar la atencion a nuestros pacientes.

    Introduccion. La esclerosis multiple es una enfermedad neurologica desmielinizante que suele provocar trastornos motrices, perceptivos, afectivos y cognitivos a quienes la padecen. Estos sintomas pueden llevar a la persona a perder su empleo, y disminuir la calidad de vida del paciente y sus familiares. Objetivo. Revisar estudios sobre variables demograficas, clinicas, cognitivas, psiquiatricas, laborales y sociales asociadas con la situacion laboral. Desarrollo. Estudios transversales y longitudinales han detectado variables relacionadas con el desempleo. Las investigaciones empiricas muestran una influencia clara de la discapacidad fisica, la fatiga y el curso de la enfermedad sobre la situacion laboral. Sin embargo, el genero, la depresion, la edad, la duracion de la enfermedad y las variables cognitivas no poseen el mismo grado de evidencia. Caracteristicas de la ocupacion, como discriminacion laboral, actitud del empleador, leyes laborales, actitud de los compañeros de trabajo y dificultades en el transporte han sido variables poco consideradas. Conclusiones. Muchos de los factores que determinan la perdida de empleo en un paciente con esclerosis multiple pueden identificarse a tiempo para poder modificarlos o compensarlos. Los conocimientos aportados por los estudios reseñados permiten detectar a aquellos pacientes que se encuentran en riesgo de perder su empleo para realizar intervenciones posibles con el objetivo de prevenir esta situacion. En particular, el perfil de vulnerabilidad incluye alta discapacidad fisica y fatiga, curso progresivo de la enfermedad y presencia de deterioro cognitivo, entre otros.

    Introduccion. Los conocimientos que la neurociencia basica y el neurometabolismo estan aportando en epilepsia pediatrica, y en concreto en mecanismos de comunicacion sinaptica, crecen rapidamente. Existe, no obstante, una desconexion entre estos avances y una vision que los integre de manera global y en la practica clinica y terapeutica. Objetivos. Ofrecer una vision integradora de los diferentes mecanismos moleculares y metabolicos que se conocen y postulan en epilepsia pediatrica, y sugerir conceptos como el de 'metabolismo sinaptico' y 'fenotipos sinapticos' como herramientas utiles para desarrollar este enfoque. Desarrollo. Se revisan los estudios mas destacados que intentan explicar las caracteristicas esenciales de la comunicacion sinaptica en el cerebro en desarrollo, a traves de diferentes moleculas, basicamente proteinas sinapticas, canales ionicos (cotransportadores de cloro, sodio y potasio), la compartimentalizacion pre y postsinaptica, y los principales actores metabolicos (neurotransmisores, metabolismo energetico, factores de crecimiento y lipidos). A partir de esta combinacion de mecanismos biologicos se sugieren ejemplos de 'fenotipos sinapticos' en dos casos concretos de epilepsia genetica (SCN1A) y metabolica (epilepsia con respuesta a la piridoxina). Conclusiones. Una perspectiva holistica, entendiendo la diversidad de elementos relacionados y que suceden en determinados momentos del neurodesarrollo, puede ayudar a delinear fenotipos, vias de metabolismo sinaptico y conectividad cerebral, que faciliten no solo la comprension de la fisiopatologia, sino nuevas aproximaciones terapeuticas en epilepsia pediatrica.

    Full Text Available FUNDAMENTO: El tiempo de espera para acceder a la consulta está considerado un indicador de satisfacción. Las visitas no urgentes, realizadas sin cita previa, provocan un incremento del tiempo de espera de los pacientes citados, con la consiguiente insatisfacción de los mismos. El objetivo del estudio persigue la valoración cuantitativa de este tipo de visitas y conocer las características de las mismas, para introducir las medidas destinadas a su corrección y racionalización. MÉTODOS: Estudio descriptivo. Se realizó un registro que recogiera las características de los pacientes que originan las consultas sin cita previa, como la edad y el sexo y las relativas a la consulta: motivo, modalidad, jornada laboral y si era realizada de forma directa o indirecta. RESULTADOS: El 14,19% de consultas a demanda no urgentes son sin citación previa. Con el análisis factorial de correspondencias múltiple se identifican dos perfiles de consultas: las directas, solicitadas por pacientes jóvenes, por enfermedad o tareas burocráticas, al final de la consulta de la mañana, estando ellos presentes, y las consultas indirectas, ocasionadas durante las consultas con cita previa por pacientes que solicitan recetas. CONCLUSIONES: Hay un elevado número de visitas sin cita previa. Son precisas medidas que puedan conducir a la utilización del sistema de organización de las consultas y a la mejora de aquellas situaciones que impliquen una falta de accesibilidad, con la finalidad última de mejorar la satisfacción de los usuarios de los servicios sanitarios públicos.

    Full text: BeOSL system of Dosimetric s is very easy to use, assimilate and maintain. Our dosimeter defines a milestone in the supervision of personal equivalent dose of Hp (10) and Hp (0.07) it covers the range of total energy of 16 KeV to 10 MeV. For this energy range is exceptional in its energy dependence for official personal dosimetry. The BeOSL system consists of two modules, one of them is the BeOSL reader that measures the radiation exposure using the latest technology, optically stimulated luminescence (OSL). The reading is extremely fast; it does not require consumables such as nitrogen or other. The detector material is beryllium oxide (Be O); this is an OSL material tissue equivalent and therefore is ideal for personal dosimetry. The BeOSL technology allows multiple readings of the dosimeter (re-read) to verify the dose or archive the dosimeter. One of the biggest advantages of BeOSL system is its modular concept allows the system to run as a manual solution or as a complete automated robotic system, which can be filled with up to 5,000 dosimeters as bulk cargo.

    In this work has been investigated the influence of the TEOS/PDMS hybrid size during the pyrolysis process to obtain the related silicon oxycarbide glasses. Hybrids monolithic pieces (100 mm x 50 mm x 5 mm), were crushed (1 mm x 1 mm x 1 mm) and grounded in agate or attrition to 16 and 3 {mu}m, respectively. Then, they were pyrolyzed at 1100 degree centigrade to obtain silicon oxycarbide glasses (SiOC). These materials present structural and microstructural differences. The monolithic sample showed the highest %C into the silica network (34 %), and after grounding in agate mortar decreased to 26 %. However the attrition milled sample reached %C values similar to the monolithic (32 %). This agrees with FT-IR band at 880 cm-1 assigned to Si-C bonds formation and related to higher carbon content into silica network. The carbon free phase displays a domain size of 3.44 nm which increased to 3.66 nm for the attrition milled. This result is due to a higher graphitization degree. The SiOC monolithic sample morphology displays spherical interconnected particles with pores of 12 {mu}m. This morphology disappeared for the SiOC attrition milled sample, formed by irregular particles of 3 {mu}m. (Author) 38 refs.

    The aviation technology in the world, is to use gas turbines engines feted for fuel type Jet A1. The main exigency of quality for this products is concentrated in extreme security and secure answer during the functioning. The conductivity and thermal stability to oxidation are the principals characteristics to assure these quality exigencies. The use of additives is the methods most used for establish the quality for international specification. The incorporation of heavy crude oils in mixtures to produce fuels has caused a diminution of the quality of the derivatives produced. High viscosity, density and high sulfur content in the heavy crude oils affect some of properties of the jet fuel, influencing in its composition, increasing the mercaptanes and total sulfur content, getting a jet fuel unstable, with low conductivity and highly corrosive. So, for obtain the quality required internationally is necessary use additives. This paper study how the heavy crude oils affect the conductivity and the thermal stability of the jets fuels type Jet A1. Also analyze of the use of dissipater electrostatic and antioxidants additives, to improve these properties in the jet fuel. (author)

    The present paper addresses the alkali activation of Portland cements containing blast furnace slag (20 and 30% by cement weight) with a view to the possible use of these materials in oil well construction. The hydration studies conducted showed that in cement/slag blends, the sodium silicate activator partially inhibited the dissolution of the silicate phases in the Portland cement, retarding cement hydration and reducing the precipitation of reaction products. Due to such partial inhibition, the cement/slag blends had significantly lower mechanical strength than Portland cements hydrated with water. {sup 2}9Si and {sup 2}7Al MAS NMR and BSE/EDX studies, in turn, showed that the CSH gel forming in the alkali-activated cement/slag pastes contained Al in tetrahedral positions and low Ca/Si ratios.

    Due to its special characteristics, quality control in digital radiographic systems is very important, even more than in conventional film-screen systems. Differences between digital and analogical images,a in terms of dynamics range, spatial and contrast resolution, and the flexibility of data post-processing require some actions to maintain clinical images in an optimum quality level. Revision 1 of the Spanish Protocol of Quality Control in Diagnostic Radiology includes a chapter dedicated to the quality control of these digital systems for the acquisition of radiographic images. In this paper the different parameters for quality control procedures are described. Also some difficulties to be concerned about (absence of levels of tolerance, access to the raw-data images and related information, availability of use anthropomorphic phantoms, etc, etc) are noted, as well as the most significant aspects of the differences in relation to the ana logical systems.

    This paper is the second part of a general study about physic-geometrical and fluid-dynamics characteristic of the sugarcane bagasse particles. These properties has relevant importance on the dimensions and operation of the equipment for transport and treatment of solid particles. Was used the transport column method for the determination of the drag velocity and later on the drag coefficient of the sugarcane bagasse particles was calculated. Both, the installation and experimental technique used for materials of these characteristics are simple and innovations tools, but rigorous conceptually, thus the results obtained are reliable. Were used several sugarcane bagasse fractions of particles of known mean diameter. The properties determined were expressed as a function of Reynolds and Archimedes a dimensional criteria. The best considered model from statistical analysis (model from equation 8) was statistically validated for determined ranges of Reynolds and Archimedes. These empirical equations can be used to determine these properties in the range and conditions specified and also for modeling some processes where these fractions are employed. (author)

    This study aims to evaluate the structural and morphological characteristics of a composite polyamide 6 with 50% loading of nickel ferrite. The ferrite was obtained by combustion synthesis and calcined in muffle furnace at 700 deg C. The polymer matrix was previously dried in vacuum oven at 80 deg C / 48 h to eliminate moisture. The composites were characterized by XRD and SEM. XRD results show the incorporation of cargo in the matrix, and that increasing temperature led to a considerable increase in crystallinity. The particle size of the load in the matrix was changed by increasing temperature. (author)

    The influence of electrical discharge machining (EDM) on the abrasive wear resistance of two WC-10 %{sub w}tCo cemented carbides with different carbide grain size has been studied. Different surface finish conditions were evaluated corresponding to sequential EDM as well as grinding and polishing with diamond. The abrasive wear resistance was determined through microscratch measurements using a nano indentation system. Contrary to the results obtained from hardness measurements, this techniques allows to discern tribological differences among the distinct surface finish conditions studied. Finally, the abrasive wear resistance degradation associated with sequential EDM is discussed as a function of microstructure in terms of a damage parameters. (Author) 9 refs.

    Full Text Available En la búsqueda de una forma terminada para una vacuna oral anticolérica, se estudió el efecto de la adición de fosfato tricálcico como antihumectante y de ácido cítrico como antioxidante, a dos formulaciones con efecto ya probado para conservar la cepa vacunal 638 de Vibrio cholerae. Se estudió el efecto de esos aditivos sobre la higroscopicidad de las formulaciones y sobre la viabilidad de la cepa bajo diferentes condiciones ambientales. Se observó que la formulación A liofilizada, compuesta por lactosa + peptona + sorbitol, es menos higroscópica que la formulación B compuesta por leche descremada + peptona + sorbitol y que la presencia de fosfato tricálcico disminuye la higroscopicidad en ambas formulaciones. En estado líquido, ambas formulaciones con dichos aditivos, sufren una disminución del pH pero no se afecta la viabilidad. En estado liofilizado, la formulación A con aditivos, mantiene una mayor viabilidad durante el almacenamiento ante la acción de una humedad relativa superior al 33 %. Sin embargo, aunque la protección contra la humedad haya sido mayor, las pérdidas de viabilidad en el entorno de tres órdenes logarítmicos, hacen descartar tales aditivos para una formulación final. La protección de las células contra el oxígeno, fue superior cuando se empleó la formulación A. Sin embargo, la adición de ácido cítrico no tuvo efectos sobre la viabilidad en ninguna de las formulaciones cuando se almacenaron en un ambiente conteniendo oxígeno.

    Full Text Available A análise de crescimento de três cultivares de milho, de níveis heteróticos, portes e ciclos distintos, foi realizada visando avaliar os seguintes índices biométricos e fisiológicos: distribuição percentual de matéria seca entre as diversas partes de planta, taxa de crescimento da cultura, taxa de crescimento dos grãos, índice de área foliar e taxa de assimilação líquida. Esses índices foram determinados através da variação temporal da área foliar e da matéria seca das diversas partes da planta. Os cultivares IAC-Maya e IAC-Maya latente não apresentaram diferenças entre si quanto às características estudadas, porém diferiram do híbrido duplo precoce Cargill-601. No período imediatamente após o florescimento, os fotossintetizados produzidos em excesso à capacidade de enchimento dos grãos, foram armazenados principalmente nos colmos, sendo posteriormente reutilizados no período de maior crescimento dos grãos. Embora os cultivares IAC-Maya e IAC-Maya latente tenham apresentado maior capacidade fotossintética, foram menos eficientes que o híbrido duplo Cargill-601 na taxaa de conversão de fotossintetizados em grãos. De maneira geral, os híbridos são mais eficientes que os cultivares na conversão de fotossintetizados em grãos, em vista do nível heterótico. Os valores dos índices de colheita para os cultivares IAC (Maya e Maya latente e para o híbrido duplo precoce Cargill-601 foram, respectivamente, 0,37 e 0,50.Growth analysis of three maize cultivara, of distinct vegetativa cycles and plant heights, were carried out in order to estimate the following biometrical and physiological characteristics: dry matter distribution among the plant parts, crop growth rate, grain growth rate, leaf area index, and net assimilation rate. These characteristics were evaluated from the temporal variations of leaf area and dry matter accumulation among the plant parts. For all the characteristics determined, both IAC-Maya and IAC-Maya latente did not differ from each other, but were distinct from Cargill-601. Just after flowering the photosynthates produced in excess of the grain filling capacity were accumulated mainly in the stem being, however, available during the period of grain growth. Although IAC-Maya and IAC-Maya latente had higher photosynthetic capacity they were, however, less efficient than Cargill-601 in converting photosynthates to grain. The harvest indexes were 0.37 and 0.50, respectively, for IAC (Maya and Maya latente and Cargill-601.

    The post-harvest quality of the pineapple cultivar Smooth Cayenne was evaluated after the fruit was irradiated with doses of 100 and 150 Gy and stored for 10, 20 and 30 days at 12 deg C ( +-1) and relative humidity of 85% (+- 5). The controls were untreated fruits. Sensorial analyses were made for each storage period to obtain information about the effects of ionizing radiation on the quality of the fruit. The ionizing radiation dosage had little effect on the sensorial characteristics of the pineapple, although the best results were obtained with fruit irradiated with 100 Gy. The 20-day storage period resulted in the highest consumer acceptability, while the 30-day storage period impaired the fruit's external and internal appearance. (author)

    Fine materials or particles are often encountered in many industrial processes and in our daily life. Some examples are: salt or sugar; sand; cleaning products; fertilizer; cement; calcium hydroxide; some residues of energy biomass, for instance, sugar cane bagasse, straw of sugar cane, saw dust, straw of rice, and even, other types of particulates as aerosols, and residual ash from combustion processes of conventional solids. During the preparation and handling of these materials and also for design and optimization of some multiphase processes and equipment associated with them, as classifying, transport and pneumatic drying, and thermo chemical conversion systems, in general, it is indispensable knowing the principal physical and fluid dynamic characteristics or properties, which not always are available or well established. In this paper the Ergun Method is employed, which is based on theoretical equations established for a fixed bed of porous particles when it is crossed by a gas flow. From this expression and measurements of pressure loss for a given flow of gas crossing the bed at different heights, it is possible to determine some physical characteristics, as bulk density, real density, porosity, sphericity, and specific surface of the bed particles. The technique used for obtaining experimental data is simple but rigorous and it is possible to reproduce these data. Were tested several fractions of bagasse obtained by the conventional sieving process. Finally it was statistically processed all experimental results obtaining the corresponding mathematical models for the desired properties as a function of the mean diameter of the particles. These empirical equations can be used to determine these properties in the range and conditions specified and also for modeling some processes where these fractions are employed. (author)

    Studies on many topics have been undertaken during the exploratory and exploitation stages of the development of Los Humeros geothermal field. From a geochemical and mineralogical view-including hydrothermal mineralogy and fluid-inclusion micro-thermometry, features have been reported differing from those observed in other geothermal fields. Sometimes this has led to ambiguous conclusions. Studies of fluid-inclusion micro-thermometry have shown low-salinity and high-temperature fluids, suggesting a slight temperature decrease in the deepest portion associated with a boiling process rather than a cooling process. In 1998, Arellano et al. performed a multi-disciplinary study and proposed the existence of at least two, distinct reservoirs at depth. Mineralogical data from wells drilled at the Colapso Central zone tend to support this idea. However wells drilled in the zone known as Corredor Mastaloya seemingly show evidence of a single reservoir. [Spanish] Durante las etapas de exploracion y explotacion del campo geotermico de Los Humeros se han realizado diversos estudios cubriendo distintos topicos. Desde el punto de vista geoquimico y mineralogico (mineralogia hidrotermal y microtermometria de inclusiones fluidas) se han reportado comportamientos diferentes a los observados en otros campos del mundo, los que en ocasiones han llevado a conclusiones imprecisas. La microtermometria de inclusiones fluidas ha mostrado fluidos poco salinos de alta temperatura, asi como una ligera disminucion de temperatura en la parte profunda la cual se asocia a un proceso de ebullicion mas que a un enfriamiento del sistema. En 1998 Arellano et al realizaron un estudio multidisciplinario proponiendo la existencia de al menos dos reservorios. La informacion mineralogica de pozos perforados en la zona del Colapso Central fortalece esta propuesta. Sin embargo, para pozos localizados en la zona conocida como Corredor Mastaloya se tiene evidencia de lo que parece ser un solo yacimiento.

    Full Text Available In spite of findings of large-scale clinical trials which showed an overall reduction of morbidity and mortality from coronary heart disease in patients treated with 3-hydroxy-3-metylglutaryl coenzyme-A reductase inhibitors (statins, relatively little is still known about the real prevalence of treatment in general practice setting, particularly in patients with a high cardiovascular risk. The objective of this study was to investigate among patients with cardiovascular risk profile estimated according to the Framingham Heart Prediction Risk Study, the percentage of those exposed to statins, and the proportion of patients reaching total cholesterol (TC target levels. A cross-sectional analysis was conducted on a large cohort of patients listed in the administrative databases of the Local Health Unit of Ravenna (total resident population of 356,000. In 2001, every single patient who received a prescription for a statin, and/or with a recorded plasma TC level, and/or with a hospital admission for cardiovascular reasons (identified by ICD-9 code, and/or with a clinical appraisal based on the presence of cardiovascular risk factors, was defined eligible. Sebsequently, pharmaceutical, and nosocomial databases, were cross-linked with that of 50 general practitioners in order to assess the pharmacoutilization of statins on a patient-by-patient basis. A cohort of 9,208 patients with a well documented cardiovascular risk profile were analyzed. The mean age of those patients was 57 (SD=17 years and 42% of them was male. On the basis of raised TC levels and cardiovascular risk profiles, patients for whom a statin treatment was suggested amounted to 7,233. However, the number of those who received statins was significantly lower (n = 1,343, corresponding to 18.6%. In those exposed to statins, just a small group of patients reached a level of TC below 190 mg/dl (n = 271, equivalent to 20.2%. In the group of treated who did not achieve recommended TC target levels, 31.7% (n = 340 of patients was at very high cardiovascular risk. Moreover, among all patients with high plasma TC levels (n=5,890, there was a 45.7% (n = 2,690 who did not received any lipid lowering drug even though they had a high cardiovascular risk profile. Results from large population-based administrative databases suggest a remarkable level of undertreatment among patients with cardiovascular risk factors. Furthermore, many patients did not achieve recommended TC target levels with their statin treatment. Pharmacoutilization of statins in general practice reveals the need of a more careful pursuing of therapeutic goals.

    Biomaterials is the result of the application of the science of the materials to the medicine, understands a new and important spectrum of the knowledge - Science of Biomaterials. The principal aspects that determine the acting of a bio material in the human body are three: biocompatibility, mechanical properties and degradation. This work had the objective to modify and to oxidate the surface of ultra-high molecular weight polyethylene (UHMWPE). It was utilized for this modification water sandpapers and for oxidation the hydrogen peroxide (H{sub 2}O{sub 2}). The surface of UHMWPE it was modified with water sandpapers of numbers 180, 600 and 1200 mesh and oxidated with the H{sub 2}O{sub 2} in different concentrations of 35 and 60%. The samples already with its modified surfaces had been submitted to the characterization using itself the following techniques: diffraction de ray-X and Fourier transform infra-red spectroscopy. The physical modification (sanded) and chemistry (H{sub 2}O{sub 2}) of the surface of UHMWPE was important because it looks for improving the interaction techniques of the implants with the bone.

    Full Text Available The analysis of the discourses of the professionals constitutes a useful tool in the study of the medico-scientific production in the context of the medical historiography. It is emphasized in Hobsbawm´s words: “for the reconstruction of the environment and the temperament of an epoch” and of its actors, when nobody exists to remember them. A product of historical research is presented, part of the doctoral thesis “The medical professionals in the Universidad de Cartagena. Period 1908-1962. A Model of medical professional: state, centralist, anatomo-clinical and individual”. The medical discourse of Eusebio Vargas Vélez was searched in books of enrollments, tests of subjects, certificates and thesis, in the archives and libraries of the Facultad de Medicina of the Universidad de Cartagena, Colombia, in the publications of the Colombian medico-scientific societies, in hospitals in the city and in the personal archives of professors and graduates. Nine publications, seven scientific texts and five letters to education authorities were found. Five of them are related with urologic clinic. Eusebio Vargas Vélez although was educated under the medical French influence, he appropriated himself of the North American one. He was compromised with the advance of the science and the technology applied to the medicine, especially of the urology. He led the education and expansion of the discipline in the local and national area when the half of the 20th century was approaching.

    We report four cases of patients with schistosomiasis in the central nervous system and describe and correlate the radiologic findings with clinical manifestations. In one patient, cerebral involvement presented as a pseudotumoral lesion confirmed by autopsy. Three other patients had schistosomiasis in the spinal cord characterized by an intramedullary mass and radicular and leptomeningeal enhancement after administration of gadolinium. Our findings show the importance of considering schistosomiasis in the differential diagnosis of intramedullary or cerebral lesions in patients of endemic areas of schistosomiasis. (author)

    Full Text Available We assessed the performance of a Real Time PCR assay to be used for EBV viremia evaluation in clinical specimens. Sensitivity and intra-/interassay reproducibility were evaluated by using DNA serial dilutions from the Namalwa cell line. EBV DNA was analyzed in serum samples from 39 patients (pts with undifferentiated type nasopharyngeal carcinoma (UCNT, from 5 infectious mononucleosis (IM pts and from 18 healthy donors. Results obtained by Real Time PCR were compared with those obtained by quantitative competitive (QC-PCR assay.We thereafter measured the dynamics of EBV DNA load in 5 HIV-seropositive (HIV+ and 9 HIV-seronegative (HIV-, as controls pts with lymphoma, treated with high-dose chemotherapy (HCT followed by autologus stem-cell transplantation (ASCT. We found a sensitivity of 100% at 10 EBV copies. The Spearman correlation for both the intra- and the interassay reproducibility was statistically significant (r=0.99; p20 copies/reaction and >30% for EBV viral loads <20 copies/reaction. No EBV DNA was detected in healthy donors. Higher EBV DNA loads were found by Real Time PCR (range 1173-46328 copies/ml than by QC-PCR (range 450-5000 copies/ml (p<0.05. 54% of UCNT and 100% of IM pts were EBV DNA positive. Two HIV+(40% and 2 HIV-(22% pts with lymphoma had detectable EBV viremia during the follow-up. The Real Time PCR is a suitable technique for high-throughput screening and frequent monitoring of patients at risk for developing EBV-associated diseases.

    Picture archiving and communication systems (PACS) were developed as a technological response to the complex management of the growing amount of information generated by the different diagnostic imaging methods. This article documents the process of the progressive implementation, starting in January 1991, of the first complete PACS installed in our country. The system installed in our center is composed of acquisition modules for all the imaging methods (computed radiography, ultrasound, computed tomography, digital fluoroscopy and magnetic resonance), a central processing unit, an automatic optical disk for storage and a network of image viewing and diagnostic stations. The preliminary results obtained with its implementation demonstrate that PACS provide a series of functional advantages, especially at the image storage and display levels. In spite of these conveniences, the present high costs of acquisition and maintenance, together with certain technical problems as a result of its complexity, will signify that its generalized application for all imaging methods will not become a reality at most centers in the near future.

    The Pain Clinic of the CIMEQ offers treatment to patients with different pathologies, using interventional techniques as the radiology like visual guide to reach the target structure and to apply the election technique. The personnel that carry out these procedures are inserted in the program of radiological surveillance of the institution, reason for which a radiological event could be detected where the main physician responsible of the service was implied. In this work the results of an investigation are presented realized with the objective of to know the causes of the event and to determine the necessary measures to avoid that this repeats again. The investigation was oriented to three fundamental aspects: medical exam of the affected worker; evaluation of the operational procedures from the radiological protection view point; and dosimetric measurements simulating the real conditions of work for which were used ionization chamber, radiometer and PMMA mannequin. As a result of the medical exam was detected that the main physician of the service did not use during the execution of all the procedures the extremities dosimetry and that he presented a radio induced erythema in the right hand, reason for which he was separated of the activity with ionizing radiations, until the conclusion of the investigation. With relationship to the evaluation of the operational procedures from the radiological protection view point, was verified that the medical physician not carried out any collimation of the beam and he was located in the positions where the dose rate reached the maximum values, frequently introducing the hands in the direct beam; that which implied an overexposure of the superior extremities and a not optimized exposure for whole body. This result was proven with the realized experimental measurements, which gave dose estimated values in extremities of the order of the deterministic effects. The investigation facilitated to introduce modifications in the operational procedures from the radiological protection view point that allowed optimizing the occupational exposure and to avoid the appearance of deterministic effects on the workers of this practice. Parallel was carried out the completion of the protection individual media and working media that allowed the proper application of the mentioned procedures were substituted. On the other hand, this investigation pointed to that the personnel training in radiological protection matter and the control of the occupational exposure in the interventional techniques are indispensable for the safe performance of the medical practice.

    The bacteriostatic activity of fosfomycin was studied in vitro against 1,243 clinical isolations of gram-positive cocci and 4,086 isolations of gram-negative bacilli that were obtained in 1973, 1974 and in the period from January to May of 1975. MIC was determined by the agar diffusion method, quantifying it by means of the standard curve that was worked out with the strain of E. coli NCTC 10,418. A slight increase in resistance was observed in the gram-positive cocci: 64 mug/ml were inhibitory for 63% of the 249 isolations obtained in 1973, 59.1% of the 716 isolations obtained in 1974, and 57.5% of the 278 isolations from 1975. A slight loss of sensitivity was also observed in the gram-negative bacilli: the aforementioned concentration of fosfomycin inhibited 36% of the 742 isolations from 1973, 33.6% of the 2,387 isolations from 1974 and 32.6% of the 957 isolations from 1975. 933 g of this antibiotic were consumed in our hospital in 1973, 4,203 g in 1974 and 957 g in 1975. The consumption rate per patient per year was 0.15, 0.72 and 0.20 g, respectively. In conclusion, although no change was observed in the sensitivity of some bacterial strains to fosfomycin, the overall study indicates a slight decrease in the sensitivity, although it does not apparently have any relationship to the consumption of fosfomycin in our hospital.

    The diseases of the muscle-skeletal tissue are the main cause of physical disability which affects in the entire world to millions of people. The bone is part of the muscle-skeletal tissue and the spine is a group of bones that are located in the dorsal part of the human body. At present the spine lesions are varied as those that people suffer when they have automobile accidents of for fallen, mainly in the major adults, if the spine lesions are not treated appropriately they can have consequences to short or long term. A procedure that has been useful for the spine lesions is the vertebral arthrodesis. The tissue banks are places where is obtained bone of distinct origin for clinical use, the chips of porous bone are obtained in banks of specialized tissues which are sterilized with gamma radiation of cobalt-60, the use of this bone type has been demonstrated that these help in the recovery of patients that suffer spine fracture. In this work the process of procurement of human bone is presented, just as the process of its transformation in chips form and its sterilization method. At the end a case of a young patient is presented who suffers an automobile accident and was treated by the vertebral arthrodesis technique of spine, using chips of porous bone for his recovery.

    Computed tomography is currently the method of choice for the diagnostic and staging of lymphomas. Computed tomography enables accurate measurements of both tumor extent and volume and provides information that can be used to plan an appropriate strategy for the treatment. The purpose of the present article is to describe and analyze the chest and abdomen computed tomography and ultrasound findings in HIV-negative patients with lymphoma. Clinical abnormalities, such as the reason the patient sought medical assistance already showing evidence of lymphocytic disease (not yet diagnosed at this point) and the physical examination abnormalities seen on the first consultation were also studied. This study comprised 30 patients: 40% with non-Hodgkin lymphoma, 46,6% with Hodgkin lymphoma, 10% with Burkitt's lymphoma and 3,3% with lymphoblastic lymphoma. (author)

    Dental caries's diagnosis is a major dentistry problem from the clinic point of view. The laser beam on the region of 655 nm induces the fluorescence of the compounds present in the hard tissue, quantifying differences between sound and carious enamel and dentine. Diagnodent (Kavo, Germany), showed to be effective regarding dental caries's diagnosis in the present research sampling. The Er:YAG laser (Kavo Key Laser 2, Germany) performed efficient cavity preparations in caries lesions of I and V class type, using up energies that ranged from 300 mJ to 350 mJ with 4 Hz repetition rate for the enamel; and from 250 mJ to 300 mJ with 4 Hz repetition rate for the dentine, and with 80 mJ with 6 Hz of repetition rate for laser conditioning. In the Er:YAG laser preparations no patient was anesthetized even when there were deeper cavities, and the maximum degree of pain ( which ranged from 0 to 10) was 4. In the control group with conventional high-speed drill two patients were anesthetized and the maximum degree of pain was 7. Restorations performed by conventional method of composite were equally satisfying both in caries groups of I and V class type and in the control group. The laser application in the operative dentistry office as a new method of diagnosis and dental preparations should be a good alternative to the use of the conventional dental drill. Nevertheless, dentistry practice has a lot to improve from technology progress, as well as new researches on laser dentistry are necessary in a long term. New types of lasers will come about and will increasingly improve the dental practice assistance and procedures quality. (author)

    Full Text Available OBJETIVO: A mielopatia cervical é uma disfunção da medula espinhal relacionada a degeneração típica do envelhecimento, cuja patologia se relaciona com a isquemia e compressão da medula. Muitos são os problemas clínicos apresentados por portadores de mielopatia, nos casos mais graves este acometimento pode levar a para ou tetraplegia quando não tratado. Devido a patologia primária desta doença ser causada por compressão gerando isquemia medular, julgamos poder existir uma correlação entre o grau de compressão e clínica dos pacientes portadores de mielopatia cervical, porém não encontramos nenhum estudo na literatura que realizou esta correlação, por existir esta dúvida na literatura é que objetivamos em nosso estudo analisar a correlação entre o grau do comprometimento clínico dos pacientes com mielopatia cervical e o índice de Torg. MÉTODOS: Estudo prospectivo, de caráter descritivo, avaliados 46 pacientes, realizado mensuração radiográfica do índice de Torg e análise clínica através da escala de JOA e Nurick. RESULTADOS: Dos 46 pacientes, 100% apresentaram Torg OBJECTIVE: Cervical myelopathy is a spinal cord dysfunction related to degeneration typical of aging. Its primary pathology is related to ischemia and spinal cord compression. Patients with myelopathy present many clinical problems; more severe cases may lead to quadriplegia if not treated in a timely manner. Because the primary pathology of this disease is caused by compression, thus generating spinal cord ischemia, we believed there must be a correlation between the degree of compression and the clinical assessment of patients with cervical myelopathy, but we did not find any study in the literature that made this correlation. Because there is doubt the literature we aimed, in our study, to analyze the correlation between the degree of clinical impairment of patients with cervical myelopathy and the Torg index. METHODS: A prospective, descriptive study, evaluating 46 patients, in which radiographic measurements of the Torg index were performed, with clinical analysis through the Nurick and JOA scale. RESULTS: Of the 46 study patients included in the study, 100% presented a Torg score <0.8. The decrease in Torg values was directly proportional to clinical worsening on the Nurick and JOA scale. CONCLUSIONS: The degree of clinical impairment in patients with cervical myelopathy is directly related to the degree of spinal canal stenosis.

    Full Text Available Toxoplamosis is a parasitic zoonosis which occurs worldwide, but is prevalent in Europe, South America and Africa. When infection occurs for the first time during pregnancy, mother to child transmission of the parasite can cause congenital toxoplasmosis. Rate of congenital infection ranges from less than 0.1 to approximately 1 per 1,000 live births. The risk of transmission depends on the gestational age at the time of maternal infection. A diagnosis of congenital toxoplasmosis is usually considered in infants who present: hydrocephalus, chorioretinitis, and intracranial calcifications, but this triade is very rare. Approximately 85% of the infants with congenital toxoplasmosis are clinically normal at birth; however, sequelae of infection may become apparent only months or even years later. Chorioretinitis is the main complication of congenital toxoplasmosis, late onset retinal lesions and relapse can appear many years after birth, but the overall ocular prognosis is satisfactory when infection is identified and treated accordingly. Fortunately, serious neonatal forms and severe neurological impairment have become rare, but prompt treatment of children with convulsions, abnormal muscle tone, hydrocephalus, may improve the prognosis and result in almost normal outcome. For infants who have congenital toxoplasmosis, treatment soon after birth for 1 year with pyrimetamine, sulfadiazine and leukoverin led to remarkable resolution of serious, active disease. A long follow-up is necessary to assess the long-term outcome of children and young adults with congenital toxoplasmosis, that is favourable for the majority of cases. Epidemiological surveillance needs to be improved in order to determine the effectiveness of prevention programs.Articoli Selezionati del “3° Convegno Pediatrico del Medio Campidano” · Guspini · 25 Maggio 2013Guest Editor: Roberto Antonucci

    A survey was conducted in the urban area of Lages using patients who had been submitted to a computed tomography of the skull in the period of March-December, 1996, for different reasons. Forty-two patients with a provisional diagnosis of neurocysticercosis, and 57 negatives were personally interviewed by one of the authors (Pfuetzenreiter), using a semi-structured procedure. More individuals with a provisional diagnostic of neurocysticercosis reported clinical manifestations related to this infection than those found negative. this difference is more marked among women, except in relation to convulsions, more frequently reported by men (19.05%) than by women (7.14%). The greater percentage of inactive forms (83.33%0 and a longer history of perceived symptoms among those positives suggest that the condition is not new. (author)

    Full Text Available Introduction: to be premature is the main cause of perinatal morbimortality, identifyingto the infections during the pregnancy as cause of preterm labor. It has been describedthat colonization of pregnant women by the bacteria Streptococcus agalactiae entailsunfavorable effects about the maternal and neonatal health.Objective: to determine the frequency of vaginal and rectal colonization by Streptococcusagalactiae and its susceptibility to antibiotics in pregnant women with preterm labor.Methods: with prior informed consent, vaginal and rectal specimens were taken to pregnantwomen with preterm labor who admitted to the Clínica Maternidad Rafael Calvo, Cartagena,Colombia, between August 1st, 2011 and January 31st, 2012. The isolations of S.agalactiae were gotten by means of culture in selective medium CHROMagar™ StrepB. Theconfirmation of the specie was carried out by means of CRP with specific primers. Proofsof antibiotic susceptibility were done with Kirby-Bauer methods. Additionally, a form wasapplied to register socio-demographic data and medical record. As an independent variablewas used the colonization, which was correlated with socio-demographic and obstetric dataand with prenatal results. Telephonic follow-up was done for one month.Results: 93 patients were included in the study. A prevalence of 37.6% for vaginal andrectal colonization by Streptococcus agalactiae was found. 15 (16.1% newborns presentedneonatal sepsis. There were not found statistically significant differences in the perinatalresults between the colonized and not colonized groups. There were found statistically significantdifferences in the gestational age between early preterm and late preterm births.Conclusions: Although the occurrence of neonatal sepsis was associated with being earlypremature, there was not association with the colonization status by Streptococcus agalactiaein the mother. It is required the realization of studies that orientate to establishif antibiotic prophylaxis against this bacteria in the population of pregnant women withearly preterm labor contributes to reduce the rate of early-onset neonatal sepsis. Additionalstudies are needed which allow us to establish if the colonization by Streptococcusagalactiae is a risk factor for neonatal sepsis in late preterm birth.

Se ha descritoque la colonización de gestantes por la bacteria Streptococcus agalactiae conlleva efectosdesfavorables sobre la salud materno-neonatal.Objetivo: determinar la frecuencia de colonización a nivel vaginal y rectal por la especieStreptococcus agalactiae y su susceptibilidad a antibióticos, en gestantes con trabajo departo pretérmino.Metodología: previo consentimiento informado, se tomaron muestras vaginales y rectalesa gestantes con trabajo de parto pretérmino que ingresaron a la Clínica Maternidad RafaelCalvo, Cartagena, Colombia, entre 1 de agosto 2011 y 31 de enero de 2012. Los aislamientosde S. agalactiae se obtuvieron mediante cultivo en medio selectivo CHROMagar™Strep B. La confirmación de la especie se realizó mediante PCR con cebadores específicos.Se realizaron pruebas de susceptibilidad a antibióticos mediante el método Kirby-Bauer.Adicionalmente, se aplicó un formulario para registrar datos sociodemográficos e historialmédico. Se utilizó como variable independiente la colonización, la cual se correlacionó condatos sociodemográficos, obstétricos y resultados perinatales. Se hizo seguimiento telefónicopor un mes.Resultados: se incluyeron en el estudio 93 pacientes, determinándose una prevalenciade colonización vaginal y rectal por Streptococcus agalactiae del 37.6%. Entre los reciénnacidos, 15 (16.1% presentaron sepsis neonatal. No se encontraron diferencias estadísticamentesignificativas entre los grupos de colonizadas y no colonizadas en lo concerniente a los resultados perinatales. Al tomar en cuenta la edad gestacional se identificaron diferenciasestadísticamente significativas entre pretérminos tempranos y pretérminos tardíos.Conclusión: aunque la ocurrencia de sepsis neonatal estuvo asociada a prematuridadtemprana, no se encontró asociación con el estado de colonización por Streptococcus agalactiaeen la madre. Se requiere la realización de estudios dirigidos a establecer si la profilaxisantibiótica contra esta bacteria en la población de embarazadas con trabajo de partopretérmino temprano contribuye a reducir la tasa de sepsis neonatal temprana. Se necesitanestudios adicionales que permitan establecer si la colonización por S. agalactiae esun factor de riesgo para sepsis neonatal en pre-términos tardíos. Rev.cienc.biomed.2013;4(1:20-30

    Fetal cholelithiasis was first diagnosed in 1983 and since then there have been only few reports about the presence of gallstones in the fetus. Maternal conditions, fetal or obstetrical predisposing risk factors have been proposed to have a causative role, by the pathogenesis of fetal gallstones remains unknown. Clinical sequelae of fetal gallstones are poorly understood as well as the role of fetal cholelithiasis in predisposing the adult to gallstones. They report on 3 patients whose cholelithiasis was diagnosed by obstetrical ultrasonography. Repeated ultrasound scans were performed in each patient until resolution of the US images. The goal of US was to correctly identify the number, size and US features of the material within the gallbladder. The presence of distal shadowing or comet-tail artifact was assess. Multiple, small echogenic foci without distal shadowing were recognized in the fetal gallbladder in their patients. In the third case echogenic foci disappeared during pregnancy. In all the cases, US showed no biliary tract abnormality, and neither the mothers nor the patients had clinical or laboratory findings consistent with liver or biliary diseases. The authors discuss a diagnostic protocol to detect and follow-up gallstones in the perinatal period by ultrasonography. In their experience, fetal cholelithiasis confirmed to be a self-limiting disease without complications and did not require any form of therapy. However a close follow-up is indicated in these patients until spontaneous resolution is demonstrated by US.

    Full Text Available The American Academy of Pediatrics (AAP has recently published its new guidelines for the treatment of pediatric tonsillopharyngitis; a diagnostic test for the detection of streptococci is recommended, followed by a treatment with penicillins (10 days or cephalosporins (5 days in case of positivity, and by no treatment otherwise. The success of a guideline, in general, depends on its diffusion in practice and on its adaptability to different local settings. The aim of the present study (FAST was the evaluation of the clinical and economical impact of the application of the AAP guidelines in the Italian reality. The study was conducted with the cooperation of 600 pediatricians, uniformly distributed on the Italian territory, and involved 3072 patients. The pediatricians were left free to decide whether to follow the guidelines or not. The results of the analysis indicate that only some 20% of the pediatricians adhered to the suggested protocol; the total cost (calculated in the perspective of the National Health System, with a time horizon of about 3 months per patient, nonetheless, resulted inferior in the group treated according to the proposed protocol (50,45 • vs. 53,30 •. Furthermore, a lower incidence of complications occurred in these patients. Among the “off-protocol” behaviors, two showed particularly evident misuse of health resources: inappropriate treatment after test positivity (59,15 •/patient, and treatment after test negativity (14% of the total population. Another interesting, although not surprising, result of this study was the evidence that penicillins are as effective as cephalosporins in the short-term, but significantly inferior in terms of complications, positivity for streptococci at the control test, and complications detected at follow-up.

  19. Breast cancer only detected at US. Incidental finding or clinical evidence?; Le neoplasie mammarie visualizzabili solo con esame ecografico. Reperti incidentali o realta' clinica?

    Mammography is the only technique of proven efficacy in the early diagnosis of breast cancer, even though its sensitivity is much lower in breasts that are dense or with a high parenchymal-stroma component. In the past malignant breast nodules detected at US in patients with negative mammographic and physical findings were considered incidental findings, but more recent papers report increasing numbers of breast cancers detected only at US. It was investigated the yield of US performed as a diagnostic complement in asymptomatic women with mammographic findings that were either negative or poorly readable because of dense breast. 13 women were examined: 37 to 55 years old (mean 47): 9 of them were asymptomatic and 4 had poorly specific physical findings. The patients underwent physical examination, mammography, US, micro histologic biopsy with 14G needles under US guidance and surgery. Fourteen breast lesions 7.0-15 mm in diameter were detected only by US. Mammography (2 or 3 standard views) was negative in all cases. The lesions detected only by US (10% of all carcinomas) were typified with US-guided needle biopsy and finally confirmed surgically. Though obtained in a small series, the results seem to suggest that US should be included in the diagnostic work-up, especially of women with dense breast. Also, any hypoechoic lesion detected at breast US in clinically asymptomatic women with negative mammographic findings should be further investigated with US, needle aspiration or core biopsy to make the final diagnosis. [Italian] Si intende con questo lavoro valutare l'utilita' dell'esame ecografico, eseguito come completamento diagnostico in donne clinicamente negative e con mammografia negativa o comunque scarsamente leggibile in relazione alla elevata densita' del parenchima mammario (mammelle dense). Tredici donne con eta' compresa tra 37 e 55 anni (eta' media 47 anni) asintomatiche o con quadri clinici vaghi o comunque non orientativi per patologia neoplastica della mammella hanno eseguito esame clinico, mammografia, ecografia mammaria, prelievo microistologico ecoguidato e intervento operatorio. Quattordici neoplasie mammarie, con dimensioni comprese tra 7 e 15 mm sono state evidenziate solo ecograficamente. La mammografia eseguita nelle 2 o 3 incidenze abituali, e' risultata sempre negativa. Le lesioni neoplastiche evidenziate solamente con l'esame ecografico (10% di tutti i carcinomi) sono state caratterizzate con biopsia istologica con ago da 14G e definitivamente confermate con intervento chirurgico. I risultati ottenuti permettono di suggerire che l'esame ecografico debba essere metodica da includere nell'iter diagnostico nelle donne con mammelle scarsamente leggibili. Le lesioni nodulari ipoecogene sospette rilevate all'esame ecografico in una donna con visita e mammografia negative meritano di essere ulteriormente approfondite (controllo con ecografia, agoaspirazione per citologia o biopsia istologica con ago) al fine di ottenere la definitiva caratterizzazione.

    Introduccion. El sindrome cri du chat (SCDC) tiene su origen en una delecion parcial o total del brazo corto del cromosoma 5, y es uno de los sindromes de delecion cromosomica mas frecuentes en humanos. La mayoria de los pacientes se diagnostica entre el primer mes y el primer año de vida, si bien aqui se describe el hallazgo de un SCDC en una mujer con sospecha de ataxia espinocerebelar y antecedentes familiares de trastorno bipolar y ataxia, con especial atencion a las caracteristicas clinicas y las tecnicas diagnosticas que permitieron su identificacion. Caso clinico. Mujer de 46 años que presentaba una inteligencia limite, intervenida a los 43 años de faquectomia bilateral. El inicio de la sintomatologia fue durante la infancia, e incluia hipoacusia, ataxia, disartria, disfagia, depresion, deterioro cognitivo y trastorno bipolar. La exploracion fisica revelo microcefalia, micrognatia, pies equinos y ataxia. Se realizo cariotipo y array-CGH en sangre periferica. La paciente presentaba una traslocacion que involucraba los cromosomas 5 y 15, y una inversion del cromosoma 9: 45,XX,inv9(p11q13);t(5,15)(p15.33;q11.2). El array-CGH mostro una delecion de 2,91 Mb en 5p15.33, formula genomica arr 5p15.33 (151537-3057771)x1, que involucraba 20 genes, incluyendo el gen TERT. Conclusiones. La delecion de multiples genes confirmo el diagnostico de SCDC y es la responsable del fenotipo de la paciente. Se pone de manifiesto la importancia de utilizar tecnicas adecuadas de diagnostico (array-CGH, cariotipo en sangre periferica) y la correcta eleccion de estas.

    Introduccion. Un 30-40% de los pacientes con daño cerebral presenta alteraciones del nivel de conciencia, y algunos casos, estados alterados de conciencia: sindrome de vigilia sin respuesta (SVSR) o estado de minima conciencia (EMC). La recuperacion es variable y la supervivencia esta amenazada por multiples complicaciones. Objetivos. Presentar la metodologia de trabajo del Hospital La Pedrera (HLP) para pacientes en SVSR o EMC y analizar las caracteristicas clinicas de los pacientes atendidos, la evolucion, y la situacion funcional y cognitiva en el momento del alta. Pacientes y metodos. Estudio descriptivo prospectivo de pacientes atendidos en el HLP durante el periodo 2009-2013, con diagnostico de SVSR o EMC. Resultados. El HLP trabaja mediante el metodo gestion de caso, ofreciendo una atencion integral por un equipo multidisciplinar. Los pacientes se clasifican segun objetivos asistenciales. Los pacientes con SVSR o EMC se incluyen en el programa de cuidados integrales y adaptacion. Se atendio a 23 pacientes (86,9% varones), con una edad media de 54,9 años. Etiologia: hemorragia cerebral, 30,4%; encefalopatia anoxica, 26,6%; encefalopatia metabolica, 17,3%; y otras causas, 17,3%. El 73,9% ingreso en SVSR y el resto en EMC. Evolucion: el 43,4% mejoro su situacion cognitiva inicial y el 88,8% presentaba una situacion de dependencia total en el momento del alta. Las complicaciones mas frecuentes fueron infecciones respiratorias y urinarias (53,6%). El 65,2% de los casos fueron exitus. Conclusiones. La asistencia en SVSR o EMC es compleja y precisa cuidados multidisciplinares. Casi la mitad de los pacientes mejoro su situacion cognitiva, lo que justifica una actitud proactiva que intente mejorar la calidad de vida de los pacientes y sus familias.

    Introduccion. La fiebre recurrente transmitida por garrapatas (FRTG) puede producir complicaciones neurologicas. No existen apenas estudios en España sobre el tema. Objetivo. Estudiar la prevalencia y las caracteristicas clinicas de las complicaciones neurologicas de los pacientes con FRTG. Pacientes y metodos. Estudio retrospectivo de los pacientes atendidos con FRTG durante 12 años (2004-2015) en un hospital de una zona rural del sur de España. Resultados. Se incluyeron 75 pacientes, 42 varones (56%), con una edad media de 33 años (rango: 14-72 años). Se observaron picaduras de garrapatas en nueve pacientes (12%). Los sintomas mas frecuentes fueron: fiebre en 64 pacientes (85,3%), cefalea en 41 (54,6%) y vomitos en 26 (34,6%). Se sospecho afectacion meningea en nueve pacientes (12%), de los que tres (4%) tenian signos meningeos en el momento del ingreso. A todos ellos se les realizo una puncion lumbar. Ninguno presento paralisis facial ni otra manifestacion neurologica. Se encontraron alteraciones del liquido cefalorraquideo en los tres pacientes con meningismo. En uno de los casos se visualizo Borrelia en el liquido cefalorraquideo. En los pacientes con afectacion neurologica, el tratamiento utilizado fue penicilina G en un caso y ceftriaxona en dos. Todos los pacientes se recuperaron completamente. Conclusiones. La FRTG es una de las formas menos graves de borreliosis, y menos del 5% de los pacientes presenta complicaciones neurologicas. Sin embargo, los medicos deben saber que Borrelia puede causar meningitis en los sujetos expuestos a garrapatas en regiones endemicas de FRTG.

    Objetivos. Describir las caracteristicas de la enfermedad cerebrovascular (ECV) en pacientes atendidos en un servicio de urgencias pediatrico y detectar diferencias clinicas segun sea isquemica o hemorragica. Pacientes y metodos. Estudio retrospectivo, analitico observacional, realizado en el servicio de urgencias pediatrico de un hospital de tercer nivel. Se incluyen pacientes entre 1 mes y 18 años de edad atendidos en el servicio durante 10 años (enero de 2001 a diciembre de 2011) con diagnostico final de ECV. Se excluyen las hemorragias por traumatismos o secundarias a tumores, las trombosis de senos venosos y los pacientes no atendidos en el servicio. Resultados. Se incluyen 61 pacientes, 39 (63,9%) de sexo masculino, con una mediana de edad de 4,6 años (rango: 1,3 meses-17,5 años). De ellos, 26 (42,6%) presentan ECV isquemica y 35 (57,4%) ECV hemorragica. La cefalea (n = 20; 57,1%; p = 0,008) y los vomitos (n = 25; 71,4%; p = 0,001) son mas frecuentes en la ECV hemorragica, y la hemiparesia (n = 17; 65,4%; p paralisis facial (n = 7; 26,9%; p = 0,001), en la ECV isquemica. Las principales causas de la ECV hemorragica son las malformaciones arteriovenosas (n = 17; 38,6%), y las de la ECV isquemica, las arteriopatias (n = 6; 42,3%). Al alta, 27 (44,3%) presentaban diferentes grados de discapacidad y 6 (9,8%) fallecieron. Conclusiones. La ECV es una entidad poco frecuente, aunque presenta una elevada morbimortalidad. Se observa un ligero predominio de la ECV hemorragica y se comprueba que la ECV hemorragica se presenta mas con signos de hipertension intracraneal, y la isquemica, con focalidad neurologica.

    Introduccion. Los fenomenos visuales pueden ser sintomas de crisis epilepticas, aunque con un significado clinico y una relacion con el foco epileptogeno incierto. Objetivo. Describir las implicaciones clinicas de las crisis epilepticas visuales segun su semiologia en adultos. Pacientes y metodos. Durante un año se recoge consecutivamente a pacientes que describian semiologia visual como manifestacion principal de sus crisis y se clasifican los sintomas visuales segun las caracteristicas de la descripcion. Resultados. Se incluye a 78 pacientes con una edad media de 43,5 años. El 97% de los casos eran epilepsias focales. Entre el 63% de las epilepsias sintomaticas, el 57% eran vasculares. Las crisis visuales eran, en un 81,9%, el aura previa a la crisis, y en un 17,9%, crisis visuales aisladas. La coexistencia de crisis visuales y otro tipo de crisis se asocio a farmacorresistencia (p = 0,021). Los sintomas visuales fueron: alucinaciones simples (55,1%), ilusiones (23,1%), alucinaciones complejas (15,4%) y perdida de vision (6,4%). La localizacion lobar de las lesiones era occipital (24,4%), temporoparietooccipital (21,8%), temporal (9%), parietal (3,8%) y frontal (1,3%). Las lesiones occipitales se asociaron con alucinaciones visuales simples (p < 0,001), y las ilusiones visuales y alucinaciones visuales complejas, con lesiones de la encrucijada temporoparietooccipital (p < 0,05). Del 55,1% de los pacientes con lesion unilateral en la resonancia magnetica, el 33% referia los sintomas en el hemicampo visual contralateral. Conclusiones. Las crisis visuales se presentan, principalmente, como auras epilepticas. Las alucinaciones simples se relacionan con el origen occipital, mientras que las alucinaciones complejas se asocian con regiones cerebrales mas anteriores. La aparicion de fenomenos visuales lateralizados nos orienta a un origen en el hemisferio contralateral.

    Introduccion. El estado epileptico (EE) es la emergencia neurologica mas frecuente en pediatria. Dada la posibilidad de secuelas neurologicas y mortalidad asociadas, requiere un tratamiento agresivo precoz. Pacientes y metodos. Estudio descriptivo retrospectivo a traves de la revision de historias clinicas de pacientes ingresados en nuestro hospital entre 2010-2013 con diagnostico de EE. El objetivo fue describir las caracteristicas epidemiologicas y el manejo de estos pacientes, asi como revisar la bibliografia disponible sobre este tema. Resultados. Hemos recogido 39 pacientes (25 varones) y 51 episodios de EE. Edad media: 4,8 años. Tenian enfermedad de base 22 pacientes. Dieciocho eran epilepticos conocidos y cinco tuvieron un EE previo. De los 51 episodios de EE, 33 fueron sintomaticos, 15 febriles y tres criptogenicos. Los tipos de EE fueron: 25 parciales (de ellos, 16 complejos) y 26 generalizados. El tratamiento de primera eleccion fue benzodiacepinas en 47 pacientes (40, diacepam), fenitoina en tres y acido valproico en uno. Veintisiete pacientes precisaron farmacos de segunda linea: 16, acido valproico; ocho, fenitoina; dos, fenobarbital; y uno, levetiracetam. Diez pacientes precisaron farmacos de tercera linea para la induccion del coma: el midazolam fue el mas utilizado en nuestro centro, seguido del tiopental y el propofol. Dos EE superrefractarios requirieron inmunoglobulinas y corticoides sistemicos por presentarse en el curso de encefalitis autoinmunes. Conclusiones. Debe plantearse el esquema terapeutico del EE desde el inicio de cualquier crisis convulsiva. El tratamiento es escalonado, con benzodiacepinas en la primera etapa, antiepilepticos de amplio espectro y disponibilidad intravenosa en la segunda (acido valproico, levetiracetam en el EE generalizado y fenitoina en el EE focal), mientras que el tercer nivel varia en funcion de la experiencia de cada equipo.

    Introduccion. Las convulsiones febriles son una de las causas mas frecuentes de consulta. Hasta ahora, los pacientes con convulsiones febriles complejas (CFC) deben ingresar, dado el mayor porcentaje de epilepsia y complicaciones agudas descrito clasicamente. En la actualidad hay estudios que apoyan ser menos invasivos en el abordaje de estos pacientes. Objetivo. Describir las caracteristicas de los pacientes ingresados por CFC y proponer un nuevo protocolo de actuacion. Pacientes y metodos. Analisis retrospectivo de historias clinicas de ingresados por CFC (enero de 2010-diciembre de 2013). Se ofrecen datos epidemiologicos, clinicos, pruebas complementarias y evolucion. Resultados. Las CFC suponian un 4,2% de los ingresos de neuropediatria (n = 67). Edad media al evento: 25 meses. El 47% tenia antecedentes familiares patologicos, y el 31%, antecedentes personales de convulsion febril previa. En el 54% de los pacientes, la CFC duro menos de cinco minutos; hubo recurrencia, la mayoria con un total de dos crisis y durante el primer dia (las CFC por recurrencia son las mas frecuentes). De las pruebas complementarias realizadas, ninguna de ellas sirvio como apoyo diagnostico en el momento agudo. Durante su seguimiento, cinco pacientes presentaron complicaciones. Los pacientes con antecedentes familiares de convulsiones febriles presentan mayor riesgo de epilepsia o recurrencia (p = 0,02), sin diferencias significativas respecto a la edad, numero de crisis, intervalo de fiebre, estado epileptico o tipo de CFC. Conclusiones. Las CFC no asocian mayores complicaciones agudas; las exploraciones complementarias no permiten discriminar precozmente a los pacientes de riesgo. Su ingreso podria evitarse en ausencia de otros signos clinicos y limitarse a casos seleccionados.

    Introduccion. El holter implantable permite detectar fibrilacion auricular paroxistica (FAP) oculta en pacientes con ictus criptogenico, pero se desconoce que algoritmo de seleccion tiene un mayor rendimiento y la duracion optima de monitorizacion. Objetivo. Conocer la frecuencia y el tiempo hasta detectar la FAP mediante un holter implantable Reveal XT ® en pacientes con ictus criptogenico seleccionados por sospecha elevada de embolismo cerebral. Pacientes y metodos. Criterios de seleccion: ausencia de etiologia del ictus tras el estudio completo incluyendo un ecocardiograma transesofagico, monitorizacion ECG y holter de 24 horas, asi como confirmacion de oclusion aguda embolica de la arteria intracraneal por duplex transcraneal o bien alta sospecha de embolismo por caracteristicas de neuroimagen. Tras implantar el holter Reveal XT se formo a los pacientes para que emprendieran transmisiones todos los meses o ante sintomas. Se reviso la informacion online mensualmente y se realizaron visitas clinicas en las unidades de Neurologia y Cardiologia. Resultados. Se incluyeron 101 pacientes con ictus criptogenico y al menos un mes de seguimiento: edad media de 67 años, 54 mujeres (53,5%). Tiempo medio de seguimiento: 281 ± 212 dias. Se detecto FAP oculta en 34 pacientes (33,7%) y falsos positivos en 23 (22,8%). Mediana desde el implante hasta la deteccion de la arritmia: 102 dias (rango: 26-240 dias). En un 70% de los pacientes se registraron multiples episodios de FAP. El 75% de los eventos se detectaron durante los primeros seis meses de monitorizacion. Conclusiones. El algoritmo de seleccion de pacientes con ictus criptogenico segun sospecha de embolismo cerebral se asocio a una elevada frecuencia (33,7%) de FAP oculta con holter implantable. Uno de cada cuatro eventos sucedio tras los primeros seis meses de monitorizacion.

    Introduccion. La epilepsia es una enfermedad con gran repercusion social y economica. La prevalencia deberia ser usada como la base mas importante para planificar la prevencion secundaria y terciaria. Objetivos. Identificar los pacientes con diagnostico de epilepsia en un centro de atencion primaria y determinar la prevalencia, las caracteristicas demograficas, el tipo de sindrome epileptico y el uso de los farmacos antiepilepticos. Pacientes y metodos. Estudio descriptivo transversal retrospectivo. Incluyo 196 pacientes con diagnostico de epilepsia pertenecientes a un centro de salud y revision de la historia clinica hospitalaria, con el estudio de las variables sociodemograficas y clinicofarmacologicas. Resultados. Prevalencia de epilepsia: 8,4/1.000 habitantes. Edad media: 50,3 años. Sexo: 52,6%, hombres. Ambito: 79,6%, urbano. Antecedentes familiares de epilepsia: 14,8%. Tipo de epilepsia: focal sintomatica por ictus (14,3%), generalizada idiopatica (13,8%), focal criptogenica (8,7%), no clasificada (31,1%). Edad media al inicio de la crisis: 31,6 años. Comorbilidad neurologica o psiquiatrica: 62,8%. Ultima revision: el 18,9% sin tratamiento antiepileptico, el 56,6% en monoterapia y el 24,5% en politerapia. Libres de crisis: 76,5%. Farmacos mas prescritos: acido valproico, carbamacepina, fenitoina, lamotrigina y levetiracetam. Un 78,6% sin efectos secundarios. Fallecimiento: 4,1%. Conclusiones. La prevalencia de pacientes con epilepsia fue de 8,4/1.000 habitantes y predomina la focal sintomatica por ictus. Casi un tercio de los pacientes referia algun factor desencadenante de crisis, principalmente consumo de alcohol o fiebre.

    Introduccion. Las hemicraneas son cefaleas raras caracterizadas por dolor estrictamente unilateral, bien como una cefalea continua, aunque fluctuante, en la hemicranea continua (HC), o en forma de ataques recurrentes en la hemicranea paroxistica (HP). En ambos tipos de cefalea se describe una respuesta absoluta a la indometacina. Objetivo. Analizar el cumplimiento de los criterios diagnosticos actuales para HC y HP, y la reciente introduccion de la HC en el grupo de las cefaleas trigeminoautonomicas. Pacientes y metodos. Evaluamos retrospectivamente las caracteristicas clinicas y terapeuticas de pacientes diagnosticados de HC o HP. Incluimos informacion demografica, sintomatologia, escala analogica de dolor y respuesta a la indometacina. Resultados. Evaluamos una muestra de 12 pacientes con HC (cuatro hombres y ocho mujeres) de un total de 520 casos (2,3%). Edad media de inicio: 47,1 ± 16,4 años. Intensidad de dolor basal: 3,3 ± 1,9. Exacerbaciones: 9,2 ± 1,1. Ocho casos (66,7%) presentaban sintomas autonomicos, cuatro (33,3%) tenian patron horario y dos (16,7%) no respondieron a la indometacina. Evaluamos una muestra de 11 pacientes con HP (100% mujeres) de 520 casos (2,1%). Edad media de inicio: 37,0 ± 13,9 años. Intensidad de dolor: 8,7 ± 2,7. Nueve casos (81,8%) presentaban sintomas autonomicos, tres (27,3%) tenian patron horario y uno (9,1%) no respondio a la indometacina. Conclusiones. Las hemicraneas son diagnosticos infrecuentes en consultas de cefalea. Su diagnostico requiere el cumplimiento de unos criterios que a veces no se cumplen en su totalidad. Pensamos que se precisa una revision de los criterios y apoyamos que la HC se haya introducido recientemente en el grupo de las cefaleas trigeminoautonomicas.

    Introduccion. El sindrome de dolor posmastectomia puede afectar a mas de la mitad de pacientes intervenidas por cancer de mama. Objetivos. Revisar las caracteristicas clinicas de este sindrome y su evolucion, y evaluar la respuesta al tratamiento farmacologico. Pacientes y metodos. Estudio retrospectivo de 65 pacientes con un seguimiento superior a cinco años. Resultados. El 88% de las pacientes estaba sin diagnosticar. Su edad media era de 56,49 años y permanecieron con dolor un promedio de 29,15 meses. En el 71%, las alteraciones neurologicas correspondieron al segundo nervio intercostobraquial. La media en la puntuacion de dolor antes del tratamiento fue de 66,5 puntos en la escala analogica visual y de 13,14 en el indice de Lattinen. El tratamiento con gabapentina (dosis media: 1.135 mg/dia; duracion media: 14 semanas) disminuyo el dolor en el 80% de las pacientes (p < 0,0001). La mejoria se mantuvo a largo plazo. Un 10% continuo en tratamiento y el 10% debio suspenderlo por efectos secundarios. El numero necesario de pacientes que hubo que tratar fue de 2,13. Recidivo el 35% y preciso cambiar de farmaco el 15,68% de las tratadas con gabapentina, frente al 50% de las tratadas con otros farmacos (p = 0,046). No se encontraron diferencias en la eficacia entre ambos grupos. Conclusiones. El dolor posmastectomia es una patologia infradiagnosticada. El tratamiento (en especial con gabapentina) puede ser eficaz y bien tolerado hasta en el 90% de las pacientes de forma significativa.

    Introduccion. El concepto de calidad de vida tiene gran importancia en la intervencion dirigida a las personas con discapacidad. Resulta indiscutible que el alcance de una calidad de vida satisfactoria debe ser el objetivo de las intervenciones clinicas dirigidas al colectivo de personas con trastorno del espectro autista (TEA), y un elemento clave para diseñar los tratamientos necesarios que mejoren el pronostico de desarrollo futuro. A pesar de ello, el conocimiento sobre las condiciones objetivas y subjetivas que predicen una mayor satisfaccion en las personas con TEA es aun muy limitado. Objetivo. Explorar la percepcion de la calidad de vida que experimenta un grupo de niños y adolescentes con TEA sin discapacidad intelectual asociada. Pacientes y metodos. Muestra de 12 niños y 11 adolescentes con TEA sin discapacidad intelectual asociada. Dependiendo de la edad, se les aplico el cuestionario de calidad de vida especifico. Resultados. Ambos grupos informan positivamente sobre su calidad, sin que existan diferencias en las dimensiones basicas. No obstante, en el caso de los adolescentes se obtienen puntuaciones mas bajas en el area de autodeterminacion en comparacion con las demas. Conclusiones. La discusion se centra en la identificacion de las dimensiones mas relevantes para la calidad de vida, las implicaciones para la intervencion y la necesidad de adecuar las metodologias empleadas para la evaluacion subjetiva de estos factores, debido a que las caracteristicas de los TEA pueden alterar las habilidades necesarias para la valoracion de la experiencia personal y requerir la adaptacion de los procedimientos empleados.

    Introduccion. Los pacientes con esclerosis multiple (EM) frecuentemente desarrollan disfuncion anorrectal. Las estructuras neuromusculares del suelo pelvico y los mecanismos de control voluntario de la defecacion pueden afectarse por las lesiones parcheadas de la EM o secundarias a la discapacidad del paciente. La implicacion multifactorial limita la comprension de la fisiopatologia de la disfuncion anorrectal en la EM. Tests neurofisiologicos especificos valoran la funcionalidad de los elementos del sistema nervioso central y periferico implicados en las disfunciones anorrectales. Objetivo. Proponer un protocolo diagnostico de estudios neurofisiologicos estandarizados del suelo pelvico para caracterizar la fisiopatologia de la disfuncion anorrectal en los pacientes con EM. Pacientes y metodos. Se realizaron estudios de electromiografia de esfinter anal externo, potenciales evocados somatosensoriales desde el nervio pudendo interno, registro de reflejos sacros anales y neurografia del nervio pudendo a 16 pacientes con EM definida y criterios de estreñimiento o incontinencia fecal. Resultados. Las caracteristicas clinicas y neurofisiologicas fueron heterogeneas. Nueve pacientes presentaron estreñimiento; dos, incontinencia fecal aislada; y cinco, combinacion de ambos. La abolicion o el retraso de la latencia de los potenciales evocados somatosensoriales fue el hallazgo mas frecuente (n = 12), seguido de la deteccion de contraccion paradojica (n = 11) y de reclutamiento deficitario (n = 8) en la electromiografia de esfinter anal externo. Conclusiones. La correcta interpretacion de cada test neurofisiologico disponible y la correlacion de los hallazgos en conjunto permiten comprender la fisiopatologia de la disfuncion anorrectal. La protocolizacion de estudios neurofisiologicos del suelo pelvico permite ajustar el diagnostico al identificar la lesion nerviosa, central o periferica, determinante de disfuncion anorrectal en los pacientes con EM.

    Full Text Available Se dispone de una extensa literatura científica que confirma que las disfunciones temporomandibulares (DTM presentan una mayor incidencia en mujeres. El objetivo de esta revisión es determinar si el proceso hormonal generado mediante el ciclo menstrual influye en las DTM que presentan sintomatología dolorosa. Se realizó una búsqueda de artículos científicos en las bases datos Medline, Embase, Scielo y CINAHL, entre los años 1970 y 2008. Se incluyeron estudios con diseños de cohortes y de casos y controles, donde se valoraron diversas variables del dolor durante el ciclo menstrual de personas que presentaban DTM. Dos revisores independientes valoraron la calidad de los estudios utilizando la Newcastle-Ottawa Scale. Se seleccionaron para el análisis cualitativo 4 estudios que cumplieron los criterios de inclusión propuestos. Los resultados de los estudios analizados son contradictorios, y por este motivo esta revisión no permite establecer conclusiones afirmativas en relación con el hecho que el factor hormonal femenino influye en la percepción del dolor en las DTM. Consideramos que es necesario realizar una mayor cantidad de estudios donde se investiguen los diversos aspectos del sexo femenino que puedan estar implicados en las DTM.A large body of evidence suggests that temporomandibular joint disorders (TMJD are much more prevalent in women than in men. The purpose of this systematic review was to examine whether hormone levels during the menstrual cycle infl uence TMJD when painful symptoms are present. A data extraction search strategy was performed in the Medline, Embase, Scielo and CINAHL databases from 1970 to 2008. We included cohort and case-control studies assessing several pain variables in patients with TMJD during the menstrual cycle. The quality of the studies was assessed by two independent reviewers using the Newcastle-Ottawa Scale. Four studies that met the proposed inclusion criteria were included for the qualitative analysis. The results of the studies analyzed are contradictory and consequently do not allow us to conclude that female hormone factors strongly infl uence pain perception in TMJD. Therefore, further studies are required to investigate the various female sex-related factors that could be involved in TMJD.

    The mineralogy of the raw materials used in the production of ceramic tiles is a matter of great importance considering the constant necessity of finding alternatives to reduce costs and to improve the product quality. The ceramic industry of Santa Gertrudes could see a dramatic growth due to reasons that include the natural characteristics of the raw materials found in the region which are suitable for the production of ceramic tiles through the dry grinding process. In order to understand the ease of use of such clays which are sedimentary rocks of Corumbatai Formation, their plastic components made up primarily of clay minerals such as illite and smectite, and non-plastic components, including quartz (inert), feldspars (fluxe) and some contaminants, were identified with the use of X-ray diffraction. When comparing the properties of the formulation made with clays from Corumbatai Formation with that made with raw materials for the wet process, it was possible to note the ease of use and the relative characteristics of both processes.

    In this work the luminescent characteristics of the ZrO{sub 2} are presented using the method of Thermally Stimulated Luminescence (TSL), also called thermoluminescence (Tl). The powders of ZrO{sub 2} were obtained by two preparation methods: for precipitation and for evaporation of Sol-gel. The luminescent characteristics of the ZrO{sub 2} are determined using a lamp of radiation of UV light and a radiation source of beta particles of {sup 90}Sr/{sup 90}Y. Using the method of thermal stimulation the curve representative thermoluminescent of the previously irradiated material was obtained. The curve Tl of the ZrO{sub 2} irradiated with UV light presents a maximum in 180 C. Likewise, the spectrum of the curve Tl of the ZrO{sub 2} irradiated with particles beta presents a maximum centered in 181 C. While using gamma radiation like excitement source one has a spectrum with a peak centered in 184 C. When subjecting the materials obtained by sol-gel to a process of calcination at 1000 C for 24 hours a curved Tl it presents with two maxim in 185 and in 290 C respectively. The intensity of the response induced in the material it is a decisive factor to continue studying the dosimetric characteristics of the ZrO{sub 2} what allows to consider it as a potential material to use it in the beta particle dosimetry and of the UV light using the thermoluminescence method (Tl).

    The analysis carried out on different materials has shown that the quantity and type of dopants play an important role in the behaviour thermoluminescent signal induced by the ionizing radiation. More recent studies have also shown that the grain size influences strongly in the thermoluminescent signal. Plus still, the crystal growth habit and the crystalline degree have an important effect in the type and intensity thermoluminescent signal. In this sense, we present this work on the analysis of the thermoluminescent signal induced by the gamma radiation in the hydroxyapatite ceramic. Depending the growth habit, a variation of the peak temperature location, signal intensity and linearity range was observed; in particular cases a lineal relationship between glow curve and radiation dose was in the range from 2 to 1000 Gray. These results are complemented with a microstructural and crystalline degree analysis through scanning electron microscopy and X-ray Diffraction. The dose-response over the whole irradiation range opening up the possibility of employing this bio material as a dosimeter. (Author)

    The burnt fuel elements that are extracted in each charging of the Units 1 and 2 of the Nuclear Power Plant of Laguna Verde, are deposited in shelves placed in the storage reservoir designed for this end. Each cell or storage shelf has a structure type cage. Among the cells neutron absorber material is placed, (Boral), what allows to avoid the possible criticality that could settle down when accumulating in the storage the irradiated fuel elements. This boral has been designed to maintain its characteristics of thermal neutron absorber during a lifetime of the plant. To check that the wings and the Boral have not suffered some degradation or some change due to the environmental conditions in the warehouse, it is necessary to watch over their physical and chemical characteristics periodically, what is carried out by a surveillance program based on Badges or manufactured witness coupons of the same material that the wings. The badges witness are embedded in a special wing, which is placed in the place with more radiation in the pool. In this work the laboratory tests carried out in the ININ to the coupon witness 03 of the Unit 2, (II-03) are described, being presented the results and obtained conclusions. (Author)

    This article describes a methodology which was used to reduce the time required to perform experimental assessment of characteristic curves (flowrate vs. solar irradiance) of PV water pumping systems showing different configurations. The characteristic curves are proposed to be obtained from two other types of curves: flowrate vs. DC power - measured using a DC power supply adjusted to simulate the operation of the PV panel in the system, and DC power vs. solar irradiance - obtained through outdoors measurements using PV panels. It is demonstrated how is possible to reduce the number of days of outdoor measurements necessary for obtaining these curves when the systems under test show configurations using the same pumping heights or the same PV panels. The flowrates, thus also the daily pumped volumes, calculated using the curves obtained through this methodology are considered the upper limits of system performance. (author)

    The photovoltaic solar energy started to be explored intensively in the 80's when researches related to this technology received great investments because it is a clean, renewable and greatly available energy. To improve the efficiency in this form of electric energy generation it is necessary to know its characteristics in order to reach a coherent sizing and foresee in which equipment they can be installed. This project analyzes the characteristics of a water pump system fed on two batteries connected to two photovoltaic modules, with variation of the geometric height of pressure. With the increase of the geometric height of pressure, occurs the reduction of the voltage (not only in the pump but also in the battery) and of the outflow and the increase of the electric current and power.

    In the present work thermoluminescent response of dysprosium doped calcium sulfate embedded in polytetrafluorethylene (CaSO{sub 4}:Dy+PTFE) under high electron beam irradiations from linear accelerator for clinical applications was investigated. The irradiations were carried out using high electron beams (6 to 18 MeV) from a linear accelerator Varian, C linac 2300C/D, for clinical practice purpose. The electron irradiations were obtained by using the water solid in order to guarantee electronic equilibrium conditions. Field shaping for electron beams was obtained with electron cones. Glow curve and other thermoluminescent characteristics of CaSO{sub 4}:Dy+PTFE were conducted under high electron beams irradiations. The thermoluminescent response of the pellets showed and intensity peak centered at around 235 C. Thermoluminescent response of CaSO{sub 4}:Dy+PTFE as a function of high electron absorbed dose showed a linearity in a wide range. To obtain reproducibility characteristic, a set of pellets were exposed repeatedly for the same electron absorbed dose. The results obtained in this study can suggest the applicability of CaSO{sub 4}:Dy+PTFE pellets for high electron beam dosimetry, provided fading is correctly accounted for. (Author)

    Honey production in Brazil has increased considerably and gaining pro eminence on the international market, as a result many demands have become part of the productive honey chain. In addition to the analyses provided for the Brazilian legislation, international market demand products that meet the most stringent quality standards. Honey has interesting characteristics due to its constitution, but even so there are problems that can change some how your identity and quality. The application of gamma radiation is a viable proposal which promotes the reduction of bio burden without changing the constitution and most importantly the physicochemical properties, with smaller nutritional losses when compared to other treatments used in foods. This study beyond the physicochemical parameters required by Brazilian regulation also included other relevant analyses, including FT-IR ATR. Microbiological analyses were carried out on samples of pure honeys and subsequently inoculated microbial known loads to assess the action of gamma radiation in doses of 5 and 10 kGy. The triangular test was used to differentiate the irradiated and not irradiated. samples The major changes that have occurred in samples of honeys were mainly in concentrations of HMF (hydroxymethylfurfural) and diastase activity occurring a significant decrease in all analyzed samples. There was a reduction microbiological from the application of the 5 kGy, reaching absence with 10 kGy dose except Paenibacillus larvae. The sensory analysis conducted on samples of honey and honey irradiated with 5, 10 and 15 kGy doses, pointed out that there is no significant difference (5%) between irradiated and control samples. The application of gamma radiation in honeys proved a very useful method in microbiological decontamination, featuring few changes in the product at doses up to 10 kGy. (author)

    Due to the importance of calculating sensitivity and uncertainty in the calculation of field engineering, and especially in the nuclear world, it has been decided to present the main features of the new module present in the new version of SCALE 6.2 (currently beta 3 version) called SAMPLER. This module allows the calculation of uncertainty in a wide range of effective sections, neutron parameters, composition and physical parameters. However, the calculation of sensitivity is not present in the beta 3 release. Even so, this module can be helpful for participants of the proposed Benchmark by Expert Group on Uncertainty Analysis in Modelling (UAM-LWR), as well as to analysts in general. (Author)

    We describe the main characteristics of the Western La Mancha hydrological unit, encompassing the provinces of Ciudad Real, Cuenca and Albacete, in southern-central Spain. Because of its groundwater resources, volume and environmental and socio-economic implications, this unit constitutes the key to the hydrology of the Upper Guadiana River Basin. We emphasise the close relationship between surface water and ground water in the unit, its over-exploitation and its climatological peculiarities. We also describe the geometry of the aquifers, their working, both under natural and abnormal regimes, the water balance and its relationship with the neighbouring units. We have compiled and analysed water-level data from the mid-1970s until March 2011, focusing on the piezo metric evolution from 1980 to 2011, estimation of changes in ground-water storage during this period and the evolution of the water level in the Ojos del Guadiana, which is taken to reflect the health of the whole hydrogeological system. Our results clearly reveal the hydrological distress brought about by the intensive use of the groundwater resources over the last forty years and the modifications to which the system has been subjected. The wet weather experienced during the period 2009-2011 led in March 2011 to the highest groundwater level for the last 25 years. From the reference year 1980, a drop in the groundwater reserve of slightly over 1.000 Mm{sup 3} can be estimated. (Author) 31 refs.

    The main objective of the present work, is to study the effect of the addition of different nutrients and irrigation doses on the chemical and energetical characteristics of the Sorghum bicolor (L). Moench ssp. bicolor biomass. The effect of compost addition is compared with the mineral fertilization in two different irrigation doses. The experimental parcel, is located at CIEMAT-CEDER (Soria) , at 1000 m above sea level, with a extremely weather and a loam sandy soil texture. The results obtained in the tested conditions show: a) the average biomass productivity was 9.8 t d. m./ha, and no significant differences between treatments were observed. b) Mean values of the proximate analysis were 72.6 volatile matter, 6.2% ashes and 21.2% fixed carbon. The volatile matter increases (1.1%) and the ashes decreases (1.4%) for the highest irrigation dose both in plots with no addition and in plots amended with compost. c) The N, S and Cl contents decreases for the highest irrigation dose in the same cases above mentioned. Mean values of the elemental analysis were: 45.0% C, 6.3% H, 1.4%% N, 0.15% S and 0.49%Cl. d) The average High Heating Value was 18071 kJ/kg d. m. and no significant differences between treatments were observed e) For the highest irrigation doses, a reduction in the K{sub 2} O, P{sub 2} O{sub 5}, Mg and Si content, and a increase in the Al, Fe and Ti in ashes were detected.

    A comparative study of the physico-chemical characteristics of rice bran during the successive steps of its industrial processing was carried out and included white and parboiled rice brans and pelletized and defatted rice brans. Moisture, acidity and peroxide index were determined. Using extracts in petroleum ether and gas chromatography, the total fat contents and the profiles of the fatty acids were established. The tocopherols and {gamma}-oryzanol were determined using high performance liquid chromatography. The bran of parboiled rice showed the largest fat content and the lowest acidity, indicating that parboiling is the most effective process for bran stabilization. Oleic, linoleic and palmitic acids predominated in all the samples. Pelletization did not produce a loss in lipids, tocopherols or {gamma}-oryzanol. All the samples showed higher contents of {alpha}-tocopherol, intermediate contents of {gamma}-tocopherol and much lower concentrations of {delta}-tocopherol. Nine components of {gamma}- oryzanol were detected, with a major proportion of the component that eluted in the fourth position, probably ferulate of 24-methylene cycloartenol. Pelletized rice bran showed the highest tocopherol content, whereas parboiled rice bran yielded the largest {gamma}-oryzanol content. (Author) 31 refs.

    Full Text Available Mega-organs, primarily in the digestive tract, are well known to occur in chronic Chagas disease. Acute experimental infection with Trypanosoma cruzi results in parasitism of a wide range of cells, tissues, and organs, including the urinary bladder. Infection of BALB/c mice with 100,000 bloodstream forms of the Y strain of T. cruzi induced acute infection with intense parasitism of all layers of the urinary bladder. Parasites were found in the mucosa, lamina propria, muscular, adventitial connective, and fat tissue. Desquamate epithelial cells with amastigotes in the bladder lumen were also found. After 60 days of infection, mice inoculated with 50 bloodstream forms developed dilated, thin-walled bladders that had inflammatory infiltrates and foci of fibrosis replacing areas of damaged muscular layer. These lesions result from direct damage to the muscle fibers by the T. cruzi, leading to myosites, muscle damage, and scarring. Direct damage of paraganglia cells secondary to parasitism, leading to dilatation, damage of muscle fibers, and scarring with replacement of muscular tissue with connective tissue, should also be considered as a cause of functional disturbance of the urinary bladder.Os "mega-órgãos" na Doença de Chagas são bem conhecidos, especialmente os desenvolvidos no sistema digestivo. A infecção aguda apresenta parasitismo de diversas células, tecidos e órgãos, dentre eles a bexiga urinária. Camundongos Balb/c infectados com 100.000 formas sanguíneas de cepa Y de T. cruzi mostraram intenso parasitismo de todas camadas da bexiga urinária na fase aguda. Os parasitas foram encontrados na mucosa, submucosa, lâmina própria, muscular, adventícia e tecido adiposo, além das células descamadas para a luz do órgão. Para produzir a fase crônica, os animais foram inoculados com a mesma cepa, porém apenas inóculo com 50 formas sangüíneas. Após sessenta dias de infecção, detectamos dilatações da parede vesical, assim como infiltrado inflamatório e focos de fibrose substituindo áreas musculares lesadas. Este achado pode ser resultado da ação direta do T. cruzi sobre as fibras musculares levando a miosite, destruição das fibras e consequente reparo. Lesão das células paraganglionares secundário ao parasitismo deve também ser considerado como causa de distúrbio urodinâmico evoluindo com dilatação, lesão das fibras musculares e substituição das mesmas por tecido conectivo.

    Absorption machines show a similar response as a function of the external temperatures, which can be approximated by a single functional dependence of the named characteristic temperature. This equation and the normalization curve of the solar thermal collector field driving the chiller and some more approximations allow determining the driving temperature that maximizes the cooling power at any time. This results in a simple equation. It is offered for the design of solar cooling facilities and their control algorithms. Some results are offered and discussed. (Author)

    This work presents the development of models for Calculated Cetane Index (CCI) determination with the purpose of tailor it to the diesel oil sold in Brazil, using optimization techniques. As the diesel is the main fuel on the Brazilian territory, their quality is of great importance. The CCI calculation is important to evaluate the diesel quality. The standard ASTM D 4737 does not take into account the presence of cetane booster additive and biodiesel, which creates the need to recast the equation of the CCI determination. About 300 representative samples were selected of diesel in Parana, during the 2006 to 2007 period, which had their physic-chemical properties determined using the methodology adopted by the ANP - the Brazilian petroleum, natural gas and biofuel agency. The Derived Cetane Number was obtained in the IQT apparatus and several models were proposed, all with better predictive capability than the equation of the standard ASTM D 4737. It is pointed out that biodiesel can act as cetane booster additive depending upon its origin, mostly in concentrations above 5%. The methodology can be expanded to generate a representative equation for the diesel sold in the whole Brazilian territory. (author)

    Accidents involving oil spills and its derivatives on the soil and in hydric bodies are common and worrying once they endanger the quality of the ecosystem. An economical and efficient way of combating oil spills is the use of the sorption method using sorbent materials. There is a range of sorbent materials, however, the natural ones like biomass and vegetable fibers demonstrate interest due to the low cost and good sorbent capacity. There are works concerning the sorption of crude oil, however for diesel and bio diesel, which had their production increased, there is a little or even nothing exists in the literature. The aim of this work was to investigate the sorption capacity of coconut fiber (Cocos nucifera) confronting to the fuels, diesel and biodiesel and to compare them with the peat commercially used. The bio sorbents were also submitted to the physiochemical and energy characterization. Most of the tests were performed on the granulometric size range of {<=}180 {mu}m 180-425 {mu}m; 425-850 {mu}m e 850-3350 {mu}m. The coir fiber presented capacity of diesel and bio diesel sorption similar to the commercial sorbent made of peat. The determination of the calorific power of the bio sorbents shows that they can be used for energy generation before and after they are used as sorbents. This way, those materials can be used after studies of economical viability in this sector and still to increase the economy of the areas where they are abundant. (author)

    It is used daily by millions of people to communicate around the globe and is a mission-critical application for many businesses. Over the last decade, unsolicited bulk email has become a major problem for email users. An overwhelming amount of spam is flowing into users' mailboxes daily. In 2004, an estimated 62% of all email was attributed to spam. Not only is spam frustrating for most email users, it strains the IT infrastructure of organizations and costs businesses billions of dollars in lost productivity. In recent years, spam has evolved from an annoyance into a serious security threat, and is now a prime medium for phishing of sensitive information, as well the spread of malicious software. Therefore we propose an algorithm that uses a classifier as one of its components. Our proposal does not include the development of a classifier itself, instead of that it plans an adjustment in the classifier training set data in order to improve their performance.

    Concentration levels of {sup 222} Rn and {sup 226} Rn have been analyzed in water samples from boreholes belonging to the drinking water supply system around Toluca, Mexico. The {sup 222} Rn source is the decay of {sup 226} Rn within the solid matrix of the aquifer. The study was performed during the dry and rainy seasons. {sup 222} Rn concentration was determined by the liquid scintillation technique, {sup 226} Rn was determined by gamma spectrometry, the physicochemical parameters and bacteriological analysis were performed by conventional chemical techniques. Solubilized trace elements were determined by Inductively Coupled Plasma - Mass Spectrometry (Icp-Ms). The radon level fluctuations at the boreholes in Toluca city and Almoloya spring indicated differences in the radon content. At borehole Lodos Prietos 2, the temperature and radon level were systematically the highest in comparison with the other boreholes and the spring indicating a contribution of a regional flow to the water of this particular borehole. The result for {sup 226} Rn, the average {sup 222} Rn observed during the sampling period, no correspondence occurs between the radium and the radon content indicating that, radon is not supported by radium, but is incorporated into the water through fissures in the rocks in contact with the water. The radon levels obtained in house faucets which water is supplied by boreholes decrease as a function of the distance from the source borehole to the house. With the chemical composition of each one of the studied boreholes and spring a Piper diagram was draw indicating the kind of water. The boreholes and spring can be classified as bicarbonate calcium/magnesium. Almost no fluctuation on time was observed in the chemical species and trace elements only a slight increase was observed at the end of the rain season. At Almoloya, spring pollution with coliform bacteria and nitrates showed an anthropogenic contribution to the water deterioration probable and fertilizers and detritus. Most of the studied water samples were potable, however at Lodos Prietos 2 borehole the fluorine concentration was higher than the established norm. (Author)

    The gas composition of fluids produced by CP IV geothermal wells from the Cerro Prieto field was studied in order to identify different types of fluids entering the wells by estimating their temperature and excess steam. A method based on the Fischer Tropsch reaction and H2S equilibrium with pyrite-pyrrhotite as mineral buffer (FTHSH3) was used. The results for the reservoir natural state indicated the presence of fluids with heterogeneous reservoir temperature (between 275 and 310 degrees Celsius) and excess steam values, which were found from negative (boiled liquid that has lost steam when flowing to the well) to one (steam phase with zero liquid saturation). The study for individual wells in which boiling processes were identified, showed that through time, the feeding fluids consist of a two-phase mixture with different liquid/steam proportions. Also, the results suggested that a steam phase could occur at CP IV which is added to the feeding fluid, depending on the operation conditions of the wells. The origin of this steam could be the boiling of the deeper liquid due to a pressure drop. [Spanish] Se estudio la composicion gaseosa de los fluidos producidos por pozos geotermicos del sector CP IV del campo de Cerro Prieto para tratar de distinguir aportes de fluidos diferentes mediante la estimacion de su temperatura de yacimiento y del exceso de vapor. Se utilizo un metodo de equilibrio gaseoso basado en la reaccion de Fischer Tropsch y el equilibrio combinado pirita-pirrotita (FT-HSH3). Los resultados obtenidos indican que en el estado inicial del yacimiento existen fluidos que muestran heterogeneidad en los valores de temperatura de yacimiento (entre 275 y 310 grados Celsius), asi como en el exceso de vapor con valores desde negativos (liquido que despues de ebullir ha perdido vapor en su trayecto hacia el pozo) hasta uno (vapor con cero saturacion de liquido). El estudio individual de los pozos con fenomenos de ebullicion muestra que a traves del tiempo, los fluidos que los alimentan son una mezcla bifasica con diferentes proporciones liquido/vapor. Los resultados indican tambien que es probable la existencia de fase vapor en CP IV que, dependiendo de las condiciones de operacion de los pozos, se anade al fluido de alimentacion. El origen de esta fase vapor puede ser la ebullicion del liquido debido a una disminucion de presion.

    The aim of this study was to verify the influence of the apparent molecular size of aquatic humic substances on the effectiveness of coagulation with ferric chloride. Coagulation-filtration tests using jar test and bench-scale sand filters were carried out on samples of water with true color of approximately 100 Hazen units, prepared with aquatic humic substances of different molecular sizes (F{sub 1}: < 0.45 {mu}m, F{sub 2}: 100 kDa - 0.45 {mu}m, F{sub 3}: 30 - 100 kDa and F{sub 4}{sup '} : < 30 kDa). For the water samples with lower apparent molecular size fractions, greater dosages of coagulant was needed to remove the color around 5.0 Hanzen units, mainly because these water samples contain higher concentrations of fulvic acids, which exhibited a larger number of negatively-charged groups.

    Full Text Available The purpose of this study was to evaluate boars´ ejaculate during 12 months. Five boars were located in each artificial insemination farm with air-conditioned (G1 and non- air-conditioned (G2 environment, and submitted to ejaculate examination every two weeks. Scores for sperm progressive motility, concentration and morphology (MOT, CONC and MORPH, respectively were established. These scores were summed up to compound the breeding soundness examination index (BSE for pigs with amplitude ranging from 100 to 1 and four classes (A-E. There were differences in several seminal characteristics during the year within and between the farms in periods of higher temperature and temperature and humidity index. There were differences between the farms for MOT (13.1±4.0 vs. 12.0±3.6, MORPH (35.5±11.4 vs. 27.6±11.6, CONC (21.6±16.8 vs. 13.4±10.6 and BSE (70.2±21.5 vs. 53.0±18.8, and the BSE class frequencies A=17.92% vs. 0.83%, B=13.75% vs. 21.25%, C=16.67% vs. 21.67%, D=1.25% vs. 4.17% and E=0.42% vs. 2.08% for G1 and G2 respectively. Ejaculates presented season variations, with lesser quality during months with higher room temperature and temperature and humidity index. There were differences between and within farms. The air-conditioned farm (G1 presented better seminal characteristics along the year. The BSE means and its class frequencies reflected the seasonal variations of the ejaculates.

    Full Text Available The objetive of this study is to cluster selected trees of Eucalyptus grandis Hill ex-Maiden as a function of phenotypic, dendrometric and wood technology characteristics. In a 27 years old commercial stand, located in the northern coast of Rio Grande do Sul, 63 selected trees were cut down and classified to the phenotypic and dendrometric characteristics. Then, disks were taken at the base, 25, 50, 75 and 100% of the commercial height, and at the DBH, for basic density determination. From the two first logs above the DBH boards parallel to the pith were taken, with 25mm of thickness, for sawn wood qualitative evaluation. The selected trees were grouped into four distinct groups following cluster analysis. In Group I were classified the trees with a lower tendency of presenting boards with end splits while in Groups II and III were classified the trees with a lower tendency of presenting logs with end splits and, in Group IV were classified the trees with a higher tendency of presenting end splits of the boards and the logs. For these groups, by discriminant analysis, there were identified five variables with real power of discrimination (DBH, estimated log split perimeter, ratio height/diameter (rh/d, type of bark and sapwood volumetric percentage and three discriminant functions. The technique of the multivariate analyze was an efficient method of grouping the selected trees of Eucalyptus grandis. The discriminant analysis enabled the selection of variables with real power of sorting the trees and determinating the discriminant functions that allow the allocation of future trees in the cluster.

    Nowadays irradiation has been the most studied method of food conservation. The publication of thousand of papers, not just scientific but also technological, economical and social, have proved the technical validity of the irradiation method and showed the ways of how to introduce it in commercial facilities in ali countries of the modem world. Cassava is cultivated almost ali over the world and it is considered one of the most important nutritious sources of calories in human diet. Cassava is a viable food against starving in several poor areas of the world because it is an extremely resistant culture and may reach satisfactory economical yield. Cassava is a quite perishable root, characterized by fast post harvest deterioration. Because of the lack of researches about the effects of radiations in this root, the objective of the present work was to examine the gamma radiation coming from {sup 60}Cobalt as a treatment to prolong the shelflife of the root after harvesting, aiming to increase its period of commercialization and to conserve its sensorial characteristics for a longer period. Samples were washed, peeled, cleaned and diced cassava roots packed in polyethylene bags. The treatments were: control; freezing and storage at 18 deg C for 21 days; and irradiation with the doses of 8 and 10 kGy. The control and the irradiated samples were stored under ambient temperature during 21 days. All samples were analyzed at each 7 days for alterations in the physicochemical and sensorial characteristics. The samples were analyzed for pH, acidity, weight, humidity, texture and color. The irradiation did not affect the chemical characteristics of the cassava. Neither the pH nor the acidity, the most relevant variables to verify deterioration in cassava, presented significant alterations during the period of storage. Comparing the irradiated treatments, the dose of 8 kGy was that less affected the physic-chemical characteristics of the cassava and scored the highest notes in the sensorial analysis during the period of storage. It was concluded that the minimally processed cassava may be irradiated with the dose of 8 kGy and conserved under ambient temperature up to 21 days of storage without alterations in its characteristics.

    The search for a healthy life has led consumers to rethink their eating habits, consuming fruits and vegetables in place of manufactured products, therefore, the demand for minimally processed products has evolved rapidly. The kiwi fruit (Actinidia deliciosa) has high nutritional value, being rich in C vitamin especially, which has wide acceptance in consumer markets. Thus, along with papaya, passion fruit and pineapple, kiwi can be considered as an additional feature of C vitamin in the diet, or as a substitute for traditional citrus. The aim of this study was to assess the effects of gamma radiation on physical and chemical characteristics of kiwis minimally processed and stored under refrigeration, since this technology increases the shelf life of fruits and vegetables. The Kiwis was stripped, processed and cut into slices, stored in polyethylene bags of 10 cm squared and irradiated at doses of 0 (control), 1 and 2 kGy. A source of {sup 60}Co Gammacell 220, dose rate of 0.429 kGy/hour, in which each treatment had 5 replicates with 15 slices of kiwifruit per replicate. After irradiation the samples were stored in a climatic chamber at 6 degree C (near the temperature of commercial refrigerators). The following criteria were physical chemical analysis: pH, color, chlorophyll content, loss of weight, moisture, acidity and Brix. The analysis were done on 1{sup st}, 7{sup th} and 14{sup th} days after irradiation. The results indicated that gamma radiation did not induce deleterious changes in the physicochemical properties of the kiwi may be used for preservation of minimally processed kiwifruit. (author)

    A study of chemical and isotopic characteristics of rainwater at Los Humeros geothermal field was undertaken for the second consecutive year. Samples were collected in seven stations-two inside the field and five on the periphery. In 1996, a total of 99 samples were collected and 104 were collected in 1997. Of these, 19-18.26% of the total-had a negative alkalinity. The Atempan (No.5) and Campamento (No.1) stations showed the highest number of anomalous samples (31.25 and 27.8%, respectively). Anomalous samples in Perote station were not observed a result that we attribute to the predominant wind direction. The results for the Campamento station are attributed to the thermal inversion phenomena occurring when the samples with negative alkalinity were obtained. Concentrations of cations in some samples were relatively high, with the maximum concentration of calcium in the Los Humeros station (79.7 ppm) . Other significantly high values were found in the Texcal station (34.8 ppm) and Perote (33.8 ppm) due to the presence of dust particles scattered in the air and because of the lack of pavement where the sampling stations are located. Another factor affecting these figures could be the presence of block and lime factories in the neighborhood. Although measured concentrations may seem high, reports exist with similar concentrations in nongeothermal areas. Oxygen-18 and deuterium contents were determined for each stations, mixing anomalous samples. The results show that the most enriched samples correspond to the San Juan Xiutetelco, Puebla (No. 6) station and the minimum to the Perote Veracruz (No. 7) station. The concentration of SO{sub 4} has marine and industrial origins, with a contribution of the first source ranging between 10 and 25 percent. [Spanish] En el campo geotermico de Los Humeros, Puebla se realizo, por segundo ano consecutivo, la caracterizacion quimica e isotopica de agua de lluvia en muestras colectadas en siete estaciones, dos localizadas dentro del campo y cinco en la periferia del mismo. Durante 1996 se colectaron un total de 99 muestras y en 1997, 104 mas, de las cuales 19 presentaron una alcalinidad negativa, lo que representa el 18.26% del total de las muestras. Las estaciones de Atempan (No.5) y campamento (No.1) presentaron el mayor numero de muestras anomalas (31.25 y 27.8 % respectivamente). En la estacion de Perote no se encontro ninguna muestra anomala, lo que es atribuido a la direccion predominante del viento. Los resultados encontrados en la estacion Campamento se atribuyen a la presencia de fenomenos tipo inversion termica que se observaron durante los periodos en que se encontraron los valores de alcalinidad negativa. Las concentraciones de cationes fueron relativamente altas; el maximo contenido de calcio se midio en la estacion de Los Humeros (79.7 ppm), le siguieron otros valores significativos en las estaciones de Texcal (34.8 ppm) y Perote (33.8 ppm), lo que fue ocasionado por la presencia de particulas de polvo suspendidas en el aire, ya que en los sitios donde se ubican las estaciones de muestreo no existe pavimento, junto con otros factores tales como la presencia de fabricas de block y cal. Aunque las concentraciones anteriores pueden parecer elevadas, existen reportes con concentraciones similares en otras zonas. Se preparo una muestra de agua de lluvia por estacion, a partir de la mezcla de muestras anomalas de cada una de ellas. Se determino el contenido de oxigeno-18 y deuterio, encontrando que la mezcla mas enriquecida corresponde a la estacion de San Juan Xiutetelco, Puebla (No. 6) y la de menor enriquecimiento a Perote, Veracruz (No. 7). La concentracion del SO{sub 4} tiene origen marino e industrial, con un aporte del primero que oscila entre el 10-25 %.

    During the study carried out in the sewage treatment plant (STP) of the town of Sada (A Coruna), the development of filamentous microorganisms has been detected as a consequence of the incidence of sea water in the sewer system. 18 filamentous microorganisms have been detected, which cause to the biomass to appear highly dis aggregated or in the form of opened flocs with many bridges between them. Among the filaments characterised as dominants, the most problematic because of their high development are Type 021 N, Type 0961 and Nocardia, type 021N is the most difficult to remove by using the operational parameters. However, many filaments can be broken by increasing the dissolved oxygen in the system, which allows a better sedimentation of the biomass. (Author)

    Full Text Available Cerebral metastases from colorectal adenocarcinomas occur in 8% of the cases. Diagnosis is usually made when primary disease and widespread metastases are already known. We report the case of a patient with single metastases in the pineal region as the first clinical manifestation of a colorectal adenocarcinoma. A 48-year-old female with Parinaud's syndrome for 15 days prior her admission was evaluated in our clinic. She had no symptoms or signs of colorectal disease. MRI examination revealed an heterogeneous lesion with peritumoral gadolinium enhancement, located in the pineal region. The tumor was radically resected through an infratentorial/supracerebellar approach. Histology showed metastatic carcinoma and immunohistochemical examination showed gastrointestinal tract adenocarcinoma. Metastases to the pineal region are extremely rare and should be considered in the differential diagnosis of tumors of this region.Metástases cerebrais derivadas de adenocarcinomas colorretais ocorrem em 8% dos casos. Geralmente a doença primária e as metástases em outros órgãos já são conhecidas quando do momento das manifestações neurológicas. Descrevemos um caso de metástase única na região pineal que promoveu a primeira manifestação clínica de adenocarcinoma colorretal. Uma mulher de 48 anos de idade apresentava há quinze dias de sua admissão ao nosso serviço diplopia e síndrome de Parinaud . O exame de ressonância magnética revelou lesão heterogênea localizada na região pineal. O tumor foi completamente retirado por acesso infratentorial/supracerebelar. O exame histológico revelou tumor metastático indiferenciado e o exame imuno-histoquímico demostrou adenocarcinoma do trato gastrointestinal moderadamente diferenciado.

    Full Text Available PURPOSE: to describe the procedure which could be useful for teachers and speech therapists engaged within a school context, in the treatment of the phonological mistakes exhibited by children during their primary-school education. It is an attempt to present an intra-subject study and to observe the generalization suffered by the untrained phonemes and processes during the training of a phoneme. METHODS: two children with phonological impairment participated in this research. A Test of Phonology Acosta et al. (1998 was used for the analysis of the simplifications and, later on, an intervention program by minimal pairs was applied. RESULTS: the results seem to indicate that the treatment should start with the process affecting more phonemes and that the most difficult; for example, the phoneme where the process is compulsory applied, should be chosen as the one to be trained. CONCLUSION: the results showed that treatment must begin with the process that affects a major number of phonemes which have more difficulty in their production.OBJETIVO: descrever procedimento de intervenção fonológica. MÉTODOS: duas crianças com transtorno fonológico participaram do estudo. Foi aplicada a prova de Fonologia de Acosta et al.

    Optically stimulated materials are increasingly used for dosimetry in clinical settings; to be sure of the obtained reading their proper clinical characterization is necessary. Is important to know the homogeneity of a batch, reproducibility, be exposed to the same conditions of irradiation repeatedly and other dependences that could present such as energy, angular, the type of radiation which are exposed and the dose deposited in them. For characterization they were designed and implemented tests for each of the factors of interest, taking into account the need for them (calculations, manufacture of mannequins, conditions, practicality, etc.) It was shown that we can apply this dosimetry in clinical practice within a radiotherapy center, relying on the readings and practicality.

    The electric power generation, it has been one of the radiation applications of bigger weight, mainly in developed countries. Another sector of more impact is without a doubt that of the medicine. However, for a sure operation with radiations, those international organisms of radiological safety, exist every time more precise detection systems. The thermoluminescent dosimetry is one of the more reliable methods for this purpose, for that several groups of investigators from different parts of the world, they have guided its investigations in the development of new TL materials. However, to avoid underestimate or overestimation of the measured dose with the use of these materials, it should take into account it effective atomic number (Z{sub eff}) it is well known that some TL materials considered as equivalent to the tissue, presents smaller TL intensity when being irradiated with low energy photons, while the TL material known as not equivalent to the tissue, they present the supra sensitivity effect for this radiation type. Nowadays, the estimate of the Z{sub eff} has not been clear, in this work the Z{sub eff} is determined by means of the traditional methods and an own method is presented for its determination. The results of the TL signal of different materials, when being irradiated with photons of effective energy between 24 keV and 1.25 MeV and their relationship with their calculated Z{sub eff} are also presented.

The Clinical study was achieved in patients with HSDC. The treatment was realized in five sessions: the first for selection, the second for exams (clinic and X-Ray) and trying to remove the etiologic factors that could cause the HSDC. The third and fourth sessions were subjected to the radiation with that protocol: 60 mJ energy ,2 Hz frequency, 6 mm out of focus, under air cooling, 20 seconds each application which the same was repeated four times with one minute breaks, which scanning movements and without using anaesthetics. The fifth was evaluation. The patients were evaluated and registered in a subject scale of pain 0 to 3, in the beginning and end of each session of irradiation, and one month after the last session. The results showed that for the irradiated group occurs significant differences in the beginning of each session and between. For the control group did not occur significant differences in the beginning and after each session, but did show a difference between the sessions. As the control group as the irradiated group, had reduction of sensibility between the session. For the morphologic study nine teeth were selected, 7 molars and 2 pre-molars from operative dentistry discipline. Half of the surface was irradiated with Er:YAG laser, the same protocol used in vivo, and the other half was used as a control without receiving any laser irradiation. Subsequently, specimens were prepared for SEM examinations. The results showed that laser treated surfaces showed a reduction of dentine tubular diameter with partial or total closure of the dentine tubules. For the control group, it was observed bigger amounts smear layer and open dentine tubular. The results obtained indicated that the Er:YAG laser can contribute to the HSDC treatment. (author)

    In this work the determination of chemistry elements in biological tissues (whole blood, bones and organs) of dystrophic mice, used as animal model of Duchenne Muscular Dystrophy (DMD), was performed using analytical nuclear technique. The aim of this work was to determine reference values of elements of clinical (Ca, Cl, K, Mg, Na) and nutritional (Br and S) relevance in whole blood, tibia, quadriceps and hearts from Dmdmdx/J (10 males and 10 females) dystrophic mice and C57BL/6J (10 males) control group mice, using Neutron Activation Analysis technique (NAA). To show in more details the alterations that this disease may cause in these biological tissues, correlations matrixes of the DMD{sup mdx}/J mouse strain were generated and compared with C57BL/6J control group. For this study 119 samples of biological tissue were irradiated in the IEA-R1 nuclear reactor at IPEN (Sao Paulo, Brazil). The concentrations of these elements in biological tissues of Dmd{sup mdx}/J and C57B/6J mice are the first indicative interval for reference values. Moreover, the alteration in some correlation coefficients data among the elements in the health status and in the diseased status indicates a connection between these elements in whole blood, tibia, quadriceps and heart. These results may help the researchers to evaluate the efficiency of new treatments and to compare the advantages of different treatment approaches before performing tests in patients with muscular dystrophy.

    The caries prevention by using laser irradiation has been investigated during the last 30 years. The Nd: YAG laser associated with acidulated phosphate fluoride has been shown as a very promising technique for enamel caries prevention. The aim of this work was to clinically evaluate the efficiency of Nd: YAG laser associated with acidulated phosphate fluoride in pit and fissure caries prevention of children and adolescents. In this work it was determined the dye that enhance the effect of Nd: YAG laser in enamel. It was selected 242 pre-molar and molar teeth from 33 children and adolescents, aged from 7 to 15 years old. The selected teeth were free from caries or decalcification marks (active white marks) to the clinical and radiographic exams. The teeth were divided into two groups: the first group was laser irradiated and their homologous remained as a control. The right side teeth were dye-assisted Nd:YAG laser irradiated. The dye solution was a moisture of dust coal and equal parts of water and alcohol. The irradiation conditions were 60 mJ/10 Hz, optical fiber in contact mode, with diameter of 300 {mu}m, resulting in an energy density of 84,9 J/cm{sup 2}. The oclusal surface of the teeth was completely irradiated, specially on the slopes and in the deepest part of the pits and fissures. This procedure was repeated three times. In the sequence it was applied the acidulated phosphate fluoride for 4 minutes. On the left side teeth - control group- only acidulated phosphate fluoride was applied for the same time. The final examination considered the presence of caries and active white marks after a period of one year. There were statistical significant differences (p < 0.01) between the lased + fluoride group and the non irradiated group. The present study concluded that the technique used in this work can be an alternative clinical method for caries prevention. (author)

    A single - although laborious - start in the economic and clinical management of our units can be come to the knowledge of the time invested in the tasks functional, having to differentiate them, name them and even encrypt them. The time spent in performing the tasks multiplied by the annual number of these will indicate the resources necessary to achieve our objectives. In addition, pooling the values of times that members of the Unit provide analysed inter-workers dispersal, their causes and possible solutions. The establishment of relative units of value in any process benefits all workers involved in the process since it allows to know the dispersion of the times that each person employed in the development of the tasks.

    30 patients were studied with suspicion of pulmonary thrombo emboli PTE, in a period of 9 months (January-September of 1992), 20 women and 10 men, with an age range of 26 to 88 years, average of 57.59 18.89. With respect to the clinical data, 24 presented breathing inadequacy (80%). 16 tachycardia (54%), 15 with thoracic pain (50%) and 4 with hemoptysis (13%). Of the cabinet studies, 12 presented electrocardiographic changes (IF, QIII, and TIII) (40%), 14 presented abnormalities in arterial gases. In the thorax tele, 8 presented abnormality; as spill, pneumonia, diaphragmatic elevation, etc. (26.6%) and of 14 the result was not reported (46 6%). They were carried out in all the patients, the ventilatory studies and perfusories in that order. A Siemens mark scintillation camera was used, with a collimator of low energy and of high resolution; the information was stored in a floppy disk, and later on they were printed in radiographic plaques of high resolution. The ventilatory study was carried out with 30 mCi of {sup 99m} Tc-DTPA, in radio aerosol form, emitted by a micro nebulizer, to which was applied a pressure of oxygen of 10 ml-min; during 10 to 15 minutes. They took projections antero, posterior, oblique antero left and right, oblique posterior left and right, each one with an acquisition of 150000 counts, or during 5 minutes. Later on and remaining the patient in supine position, was carried out the perfusory study, applying 3-4 mCi of {sup 99} Tc-MAA for endo venous via; they took the same projections that the ventilatory study, but with a density of information greater (500 000 counts each one). Both studies are printed in a radiographic plaque of high resolution, with which is interpreted and the study is filed. (Author)

    With the aim of demonstrating the usefulness of computerised tomography (CT) findings in the planning of brain neurosurgery in gunshot victims, for prompt and successful treatment, 30 patients with brain gunshot wounds were examined with CT over 5 years. The mortality rate of firearm wounds of the skull base was 34% higher than that of the hemisphere; this is due to carotid hemorrhage and midbrain damage. Such traumas require emergency radiological diagnosis and neurosurgical treatment because of their severity and early irreversible complications. Complex operations and skilled surgeons may prevent disabling postoperative sequels. CT findings are indispensable and must be correctly interpreted. The radiologist and the neurosurgeon must collaborate closely and both must consider several diagnostic factors affecting surgical planning. [Italian] Scopo dello studio e' stato quello di dimostrare l'utilita' della semeiologia della tomografia computerizzata in relazione con la pianificazione dell'intervento neochirurgico, al fine di attuare con tempestivita' interventi chirurgici soddisfacenti e meno lesivi. Lo studio comprende 30 casi di lesioni cranio-encefaliche da arma da fuoco esaminate con tomografia computerizzata nel periodo di 5 anni. Materiali e metodi utilizzati sono analiticamente descritti. L'esperienza dimostra che nelle lesioni da arma da fuoco del basicranio si nota una mortalita' del 34% superiore rispetto a quelle piu' craniali come quelle emisferiche in relazione a emorragie carotidee e lesioni tronco-mesencefaliche. Tali traumi esigono diagnosi radiologica e terapia neurochirurgica d'urgenza per la gravita' e le precoci complicanze irreversibili. Cio' richiede interventi complessi e manualita' esperte e rapide al fine di evitare sequele postoperatorie invalidanti. La corretta e indispensabile interpretazione dei segni radiologici della tomografia computerizzata deve avvenire in stretta collaborazione tra il radiologo e il neurochirurgo, ed entrambi devono tenere conto di una vasta gamma di fattori diagnostici, prognostici e di strategia terapeutica, che influenzano il tipo di decisionalita' e di aggressivita' chirurgica.

    Purpose: To commission OCTAVIUS 4D and its arrays 729 and 1000 SRS for VMAT patient-specific QA verifications, and to provide clinical results obtained with this device. Methods: The performance of both arrays was analysed by evaluating: homogeneity, linearity, reproducibility and leakage current. The accuracy of the dose reconstruction of OCTAVIUS 4D with array 729 was evaluated through ion chamber measurements at several points of interest. The performance of both arrays was compared for the same clinical plans. Finally, results of the 3D gamma analysis performed in our hospital for more than 900 patient plans are provided. Results: Both arrays present good homogeneity, linearity, reproducibility, and negligible leakage current. Dose differences between OCTAVIUS-calculated doses and ion chamber measurements or TPS-calculated doses were within 2% for single field plans, and within 4% for clinical plans. The mean value of the local gamma passing rate (3%/3 mm) of clinical plans verified with array 729 is 89.7%, whereas for 1000 SRS it is 97.8%. Conclusions: OCTAVIUS 4D provides accurate 3D dose reconstructions from 2D dose measurements. Clinical results here presented may be used to establish reference levels for VMAT verifications with this device. (Author)

    Turbidity systems or submarine fans are considered the most important clastic accumulations in the deep sea and represent the sediment-transfer system between the hinterland source area and the deep-sea depositional sink. Their deposits contain information about global factors and local factors. Different scales and varying observational methods have contributed to the lack of a unifying terminology. In order to solve this problem several authors have proposed an elemental approach. The main architectural elements defining a turbidity sys- tem are: large-scale erosive features (mass-movements and canyons), channels and channel-fill deposits, over- bank deposits and lobes. The sediment making up these elements is principally from gravity flow deposits, the most widely recognised being the turbidity, and other submarine mass movements. The genesis and character of these elements, as well as the overall geometry of the systems, indicate they are formed by a complex inter- action between global and local factors. Various turbidity-system classifications are found in the literature, the most widely-used being based on grain size and feeder systems. Besides the scientific importance of turbiditic systems, they are predominantly studied because of the economic interest in them, as turbidite sandstones con- stitute important gas and oil reservoirs. Turbidite systems shape the sea floor of the Iberian continental margins and contribute in a large part to their outbuilding and basin in filling. They are hugely variable in size, location within the physiographic domains, style and overall geometry of the architectural elements, as well as sediment composition. The most studied Iberian turbidity fans are in the Mediterranean Sea whereas those of the Atlantic Ocean remain poorly known. (Author)

    The restoration of open cast mining land looks for the quick integration in the landscape and the erosion control of derelict areas. The characteristics of substrate can determinate the behaviour of novel system. The stony substrates used have a great Ks and a very low water storage capacity. This paper presents the results of an experiment performed on story mineral substrates amended with sewage sludge under Mediterranean climatic conditions in a limestone quarry in the SW of Barcelona (NE of Spain). the experiments was carried out at container scale and the aim was to evaluate the vegetation response in two substrates with different stoniness and with irrigation during dry period. Water content in the mineral substrate was monitored using vertical TDR probes during the experiment. The growth of introduced plants was monitored monthly. Throughout the experiment, populations of sown plants fluctuated according to the available water in the substrate. The irrigation applied was not sufficient to maintain the vegetation in summer (period of higher evaporative demand at that time of year). The volume of leachate was high and nitrates, sulfates and chlorides were washed. (Author) 4 refs.

    In the Nova Lacerda and Conquista D'Oeste regions, Mato Grosso State, SW part of the Amazonian Craton, mafic dikes trending NNW intrude the Nova Lacerda Granite (1462{+-}12 Ma), within the Jauru Domain, in the Rondonia-San Ignacio Province (1.55 - 1.3 Ga). The mafic swarm comprises diabases, metadiabases and amphibolites. Metadiabases originated from uralitization of diabases. These rocks have tholeiitic affinity and predominant basaltic composition. Some samples are andesi-basalts. The ages of diabases and metabasites are 1380 {+-} 32 Ma and 1330 {+-} 120 Ma respectively. Geochemical data indicate that the compositional variation of diabases and metadiadases is due to fractional crystallization of evolved tholeiitic magmas. The origin of the basaltic magmas is related to a heterogeneous mantle source. (author)

    The objective of this research was to verify the viability of the gamma radiation as polished rice (Oryza sativa L.) conservation method. The samples were irradiated with doses of 0.5; 1.0; 3.0; and 5.0 kGy. Analysis of the grain breakage during the enriching process, longevity and reproduction of the Sitophilus oryzae L., centesimal composition, apparent amylose content, starch paste properties, color (instrumental), and the sensorial evaluation of raw and cooked rice were performed. It was verified that the irradiation did not change the percentage of grain breakage during the enrichment process, and it caused a negative effect on the development of insects. The irradiation did not change significantly the centesimal composition and the apparent amylase content. The Tukey test (p {<=} 0.05) was conducted to verify the differences between the treatments. Gamma irradiation affected the pasting properties of the rice flour. Pasting parameters as temperature, peak, final viscosity, and setback values showed decreasing values with irradiation doses. Differences were detected in the sensorial aspect among the samples, and the sample irradiated with the dose of 1.0 kGy presented greater averages. Regarding the instrumental color parameter, it was observed the difference in the values b{sup *} indicating that the rice changed the white color for yellowish with the increase in the irradiation dose. The irradiation dose of 1.0 kGy proved the best to meet the objectives of this study. (author)

    Aluminum titanate based ceramics (Al{sub 2}TiO{sub 5}) are very appreciated by exhibiting high thermal shock resistance owing to their low thermal conductivity, low Young's modulus and low coefficient of thermal expansion. However, it is very difficult to obtain dense components of Al{sub 2}TiO{sub 5} due to anisotropy of thermal expansion and susceptibility to phase dissociation in temperature range between 1000 and 1300 deg C. In this paper, the effect of SiO{sub 2} and MgO additions are evaluated considering densification, microstructure and thermal expansion coefficient of aluminum titanate ceramics. Samples with different contents of additives and sintered at 1600 deg C for 1 h were analyzed by X ray powder diffraction, scanning electron microscopy and dilatometry. The results showed that the sintered materials are formed by equiaxial grains of Al{sub 2}TiO{sub 5} with residual content of Al{sub 2}O{sub 3}. Moreover, these additives changed the grains size distribution, the coefficient of thermal expansion and the densification of materials. (author)

    Rice is exposed to injuries especially due to the attack of insects, which represent great qualitative and quantitative losses. The aim of the present research was to verify the viability of the gamma irradiation as rice (Oryza sativa L.) conservation method; its efficiency in the control of an important pest for stored grains Sitophilus oryzae L. and the effects that irradiation may present in irradiated grains in relation to the sensory aspect and starch alterations. Samples were composed of polished rice and the gamma irradiation dosages used were 0.5; 1.0; 3.0; and 5.0 kGy, and kept at room temperature. Analyses of the grain breakage percentages during processing and the longevity and reproduction of the rice weevil were performed. Analyses of the centesimal composition, phytic acid, apparent amylose content and starch paste properties were also conducted, as well as analyses of the rice color (instrumental) and acceptability (hedonic test), aimed at the determination of the raw and cooked rice sensory quality. It was verified that the gamma irradiation did not change the grain breakage percentage significantly and caused a negative effect on the insect development. Irradiation did not change the centesimal composition significantly. No significant values of phytic acid were found because during rice processing, the outer part (bran) containing 85-92% of total phytates was removed. Values from 17.33 to 18.44% for the apparent amylose content were found, and irradiation did not affect the rice starch amylose content significantly. The paste properties results were significantly changed, where reduction on the paste temperature, decrease on the time for the occurrence of the peak viscosity, reduction on the final viscosity values were observed. The retrogradation tendency became less intense in starches with increasing irradiation dosages. Statistical differences (p<0.05) were detected in the sensory aspect between irradiated and non-irradiated samples, and the sample irradiated with 1.0 kGy obtained the highest means for the sensory attributes. For results obtained for instrumental color, a statistical difference was observed in b* values, indicating that the rice color changed from white to yellowish with increased irradiation dosages. One concluded that the use of the gamma irradiation especially at dosage of 1.0 kGy, even presenting significant difference (p<0.05) in the paste properties, obtained higher acceptance; this irradiation level did not affect the rice physical-chemical analyses and provided longer shelf-life against the attack of insects, being therefore, the recommended dosage for the conservation of the polished rice.

    The Mechanically Deboned chicken meat (MDCM) is used in traditional meat products, in greater proportion in those emulsified, replacing meat raw materials more expensive. The raw material can have high MDCM the microbial load, as a result of contamination during processing or failure during the evisceration. The irradiation process is accepted as one of the most effective technologies when compared to conventional techniques of preservation, to reduce contamination of pathogens and spoilage. However, little information is available about the use and effects of different dose rates of ionizing radiation processing. Irradiation causes chemical changes in food, a major cause of deterioration of quality of raw or cooked meat products during refrigerated storage, frozen. The objective of this study was to evaluate the effects of different dose rates of ionizing radiation on the production of Thiobarbituric Acid Reactive Substances (TBARS), color, microbiological and sensory characteristics of mechanically deboned chicken added or without added antioxidants, during the cold storage and evaluation of functional properties. The results showed that among the tested dose rates using cobalt-60 source, dose rate of 4.04 kGy.h-1 was the best for processing MDCM. Furthermore, the use of the combination of rosemary antioxidant and α-tocopherol were able to reduce lipid oxidation generated by irradiation of the samples, showed a synergistic effect to the processing with ionizing radiation in reduction of psychrotrophic bacteria count and contributed to a better sensory quality. The use of radiation in the processing FDMI did not adversely affect the functional properties studied. (author)

    Nd and Sr analyses were performed on selected granitoid plutons that intrude Archean and Paleoproterozoic domains of the Guyana shield (Venezuela). The isotopic signatures of these plutons together with the geochronologic background of the country rocks are used to constrain their magma genesis and tectonic setting within the Paleoproterozoic evolutions of mobile belts (Maroni-Itacaiunas and Ventuari-Tapajos provinces) of the Amazonian Craton. The Encrucijada Suite (2187 +- 94 Ma), which intrudes Archean rocks of the Imataca Complex, originated predominantly from partial melt of this crust, as supported by negative epsilon{sub Nd(2.1Ga)} values (-2.2 to - 4.9) and T{sub DM} ages between 2.82 and 2.49 Ga. Conversely, the plutons from the Supamo Complex (2230 - 2050 Ma) and Cuchivero Group (1980 - 1830 Ma), occurring within the adjoining Paleoproterozoic provinces, are juvenile in nature (derived from roughly contemporary protoliths). These bodies display T{sub DM} ages between 2.13 and 2.22 Ga, as well as positive epsilon{sub Nd(2.1Ga)} values (+0.74 to + 3.05). Isotopic correlation diagrams (143 Nd/144 Nd vs. 147 Sm/144 Nd and 143 Nd/144 Nd vs. time) plotted together with the plutonic rocks and Imataca Complex rocks were evaluated taking into account the geologic background of the NW part of the Amazonian Craton. Interpretation of these isotopic data supports the idea of tectonic juxtaposition between the Imataca Complex and the Maroni-Itacaiunas province during the Transamazonian orogeny (2.25 - 2.05 Ga). On the other hand, the Cuchivero Group plutons have a contrasting isotopic signature compared to the other Paleoproterozoic plutonic rocks. This is consistent with the existence of a tectonic boundary between the Maroni-Itacaiunas and the Ventuari-Tapajos province in the late Paleoproterozoic. (author)

    This paper refers to the study of the bases material of the Corumbatai Formation (Parana Basin) from a clay mine, which presents limits for its use in ceramic tiles in dry grinding process due to its hardness and, especially, the high content of organic matter in relation to the clay overlaid. The characterization of the raw material and the product was accomplished by organic carbon analysis, X-ray diffraction, optical microscopy and test-firing. Firing conditions were determined to get expanded clay, using fast firing static kiln and a continuous roller kiln, both from laboratory equipment, getting samples with variable density up to the limit of expansion, with density that can reach values lower than 0,5g.cm{sup -3} because of the formation of closed pores and an external vitreous foil which provide a high mechanical resistance to the particles.

    The incorporation of functional ingredients on breading products has grown very much lately, because of the preoccupation with the consumers' health. The linseed has awakened the interest by its high level of fiber, lignin, omega-3 and antioxidants compounds. The objective of the present work is evaluate the ionizing radiation effect of {sup 60}Co on the physical-chemical, sensorial and microbiological characteristics of bread with addition of different concentration of brown linseed. There were elaborated 3 types of bread: French roll, form bread prepared with the mixture and form bread produced with conventional ingredients. It was added smashed brown linseed on the bread dough, with concentrations of 8% and 12%. After the preparation, the three kinds of bread packed with polypropylene packages and taken to the IPEN/USP (Institute of Nuclear Energetic Research/University of São Paulo) and irradiated with doses of 6, 8 and 10 kGy. Treatments were elaborated without the addition of linseed and without irradiation, for control, totalizing 12 distinct treatments, to each bread formula tested. Chemical analyses were made (centesimal composition, anti-nutritional compounds, anti-oxidant activity, glycemic index, fat acids, complex B vitamins and minerals); physical analyses (cooking index, volume, color and water activity); sensorial analyses (preference tests and Descriptive Quantitative Analysis - ADQ); microbiological analysis and a survey about irradiated products. It could be seen that the addition of linseed was efficient to increase the level of alimentary fiber and the level of lipids on the 3 bread formula. The three kinds of bread that received the linseed addition and that were not irradiated presented increase on the level of total phenolic; however, when the samples which received the linseed addition were submitted to the irradiation process, it could be noticed the decrease of the antioxidant capacity. There was an increase on the level of omega-3, depending on the percentage of linseed added to the bread. The linseed addition was effective to raise the level of potassium, phosphorus and magnesium. But, the irradiation decrease the level of vitamin B1 and vitamin B6 of the three kinds of bread. The irradiation did not influence the quality of the obtained bread. The sample tasters, not trained, accepted the bread independently of the doses of applied radiation. The ADQ test evidenced that the sensorial characteristics of the samples depend on the ingredient variation used on the formulas and on the radiation. The irradiated samples presented mold counting considerably lower than the non-irradiated samples, which increased the shelf-life of those products. The survey reveals that the majority of the people interviewed has little or any knowledge about radiation and believe that the irradiation can generate some kind of harm for human beings. Therefore, the bread production enriched with mashed linseed and submitted to gamma radiation is promising, given that the chemical and sensorial properties were considered satisfactory, besides the increasing of the shelf-time.

    The operation of a Sewage Treatment Plant (STP) designed for 20,000 pe and located in the town of Sada (A Coruna) is studied. During the study, occasional problems of solids separation in the settling unit were detected. The results show that these disturbances were mainly due to entrance of sea water in the sewer system, which decreases the quality of the biomass generated and promotes the selective developments of filamentous microorganisms, which cause biomass flotation problems. these problems can be minimised by a better control of operation conditions, such as the increase of the oxygen level in the aeration tanks, or by the minimisation of the sea water entrance by implementing a separate sewer collection system for sewage and rainfall runoff. However, in spite of these problems, this STP operates at organic matter, suspended solids an nitrogen removal efficiencies higher than 88%, 87% and 71%, respectively. (Author)

    Full Text Available O estudo sobre redundância de hospitalização, baseado no conceito de dependência aos cuidados de enfermagem, evidenciou que, em 99 pacientes que permaneceram 25 ou mais dias internados, foram redundantes em algum momento da internação, representando um desperdício de 1094 leitos-dia (30,17% do total de leitos-dia consumidos por este grupo de pacientes . Estudou-se, também, um grupo de 102 pacientes com acompanhados durante uma semana, identificando-se 60 pacientes (59% com hospitalização desnecessária. Não se verificou diferenças estatisticamente significativas entre os grupos de pacientes redundantes e não redundantes em relação às variáveis sócio-demográficas estudadas. As condições que contribuíram com maior número de dias de redundância foram neoplasias, doenças do aparelho respiratório (pneumopatia complicada e doença pulmonar obstrutiva crônica, fraturas, hipertensão arterial com ou sem insuficiência cardíaca, acidente vascular cerebral e cirrose hepática. Face a magnitude do desperdício de recursos decorrentes da hospitalização desnecessária e riscos para o paciente da permanência prolongada no hospital, é recomendada a implantação de programas experimentais para tratamento domiciliar de pacientes crônicos.A study on redundant days of hospitalization based on the concept of nursing care dependence showed that among the 99 patients studied 68 demonstrated redundant days during their hospitalization of 25 or more days. This implies a wastage of 1094 bed-days. In another study a group of 102 patients and redundancy was identified in 60 patients. There was no significant statistical difference between the redundant and non-redundant patients according to the social and demographic variables studies. Five diseases were found to be more frequent among the redundant patients: respiratory diseases, fractures, arterial hypertension with or without cardiac failure, cerebral strokes and hepatic cirrhosis. Considering the grea wastage of material and financial resources and the risks of a long-term hospitalization for patients, it is recommended that experimental home care programmes for a more reasonable treatment of chronic patients should be tested.

    Diagnostic radiology is the main contributor to the man-made exposure of general population. Since Quality Assurance (QA) programs ensure high quality diagnostic images with the lowest possible radiation dose to the patient, it has been recommended that all introduce QA programs for their radiological facilities. Consequently it is important to check the adequacy of equipment operating parameters in diagnostic radiography facilities, to ensure that a high quality of service is delivered. The purpose of this study was to evaluate the operating conditions of diagnostic units installed in Recife, Pernambuco. The study included 31 X-ray units from both public and private diagnostic services. The following parameters were evaluated: coincidence between the luminous and radiation fields; alignment of the radiation beam; agreement between the real and preset values of kVp and exposure time; filtration; half value lower (HVL); luminance of the view box; uniformity of the luminance; illuminance of the environment. The results showed that 20% of the equipment surveyed exhibited discrepancies between the luminous and radiation fields greater than 2% of the source to skin distance. The test of kilovoltage showed that 48% of the units do not fulfill the acceptability criteria, presenting discrepancies higher than {+-} 10% between the measured and preset values. The results of the accuracy of the timer indicated that 81% of the equipment surveyed present a discrepancy greater than {+-} 10% between the time selected in the control panel and actual exposure time.The test of the filtration shown that, in 20% of the equipment, this was inferior to 2,5 mm Al. The test of the luminance of view box shown that 96% of the equipment, shown a luminance lower of 2.000 cd/m{sup 2}. Related to the test of the uniformity of the luminance, 81 % of the equipment shown a variation of the uniformity higher then 10%. The test of the iluminancy of the environment shown that 61 % of the equipment presented on iluminancy level out of the gap between 50 and 100 lux. The results of this survey showed that a high percentage of the equipment surveyed demonstrated inadequate operating conditions, reinforcing the need to implement quality control protocols in conventional x-ray units located in Recife.

    Recent recommendations by the European Union (2004) for performing lateral cranial cephalometry (LCC) state that collimation should be maximized so that only those tissues necessary are irradiated when performing clinical diagnoses, although the fact that many manufacturers do not incorporate these elements in their equipment design has been recognised (recommendations 4f). Aim: the manufacture and utilization of a collimator with a pre-patient compensating filter for LLC which may be used in most extraoraldental radiology units, as well as determining the reduction in the dose of radiation absorbed by more sensitive tissues exposed to said clinical exploration. Making use of mannequins, phantom and craniums, we constructed a collimator with a compensating filter and established the necessary technical, dosimetric and quality specifications for its clinical use. Subsequently, we studied 16 patients referred for cephalometric study, determining the radiation dose (TLDs) in both the patients (crystalline lens, frontal lobe, parotid/submaxillary/thyroid glands and brain) and in the radiographic film, as well as in different parts of the collimator/filter. Al presented we are aiming for its clinical use by carrying out LCC in another 16 patients referred of orthodontic treatment but with the pre-a patient introduction of the tested collimator with the compensating filter as a substitute for the usual technique. The collimation reduced the field or radiation by some 40% and with that, so too the radiated tissues. The compensating filter reduced the dose in tissues by some 34.2. Our collimator has allowed the radiological image to be obtained with only one third the usual radiation dose. The dose reaching the film shies only between 17% less than in the usual technique and didn't alter its diagnostic capacity. A reduction of 61,6% of the dose administered to the patient is achieved by incorporating the collimator and filter to most radiological equipment without the need for renovating or substituting existing apparatus.

    The therapy with laser emitting low intensity has been currently used in the most diverse fields of medicine as therapeutic conduct for pain. It is a non invasive, painless, non-thermal and aseptic type therapy, without any collateral effects, having a good cost/benefit relationship. However, for the therapy with low-intensity laser to result in positive effects, a correct diagnosis is fundamental, as well as a protocol of adequate application. n odontology, the majority of patients diagnosed with temporomandibular disorders (TMD), present pain and limitations in the movements of the jaw. In this work, a GaAlAs laser emitting low intensity, was used, {lambda}=785 nm, in patients having a dysfunction of the temporomandibular joint with a complaint of pain. Twenty patients were divided into two groups. The group treated received laser therapy in the temporomandibular articulations and in the muscles affected. The dose applied was 45 J/cm{sup 2}, while the ten patients in the control group received 0 J/cm{sup 2}, in a total of nine applications, carried out three times a week, during three weeks. he evaluation of the patients was made through clinical examinations of manual palpation of the masseter, temporal, cervical, posterior neck and sternocleidomastoid muscles, and measurements of opening and laterality of the mouth. The results obtained showed a diminishing of the pain and an increase of the mandibular mobility in the patients treated, when compared to the control group. These results point to this therapy as being an important tool in the treatment of pain in patients with a dysfunction in the TMJ, indicating this therapeutic modality as a co-adjuvant in these treatments.

    In this work the results of studying the thermoluminescent characteristics of the K{sub 2}F{sub 5}: Y{sub 0.99} Tb{sub 0.01} are presented. The material was characterized irradiating samples of K{sub 2}F{sub 5}: Y{sub 0.99}Tb{sub 0.01} in powder with beta radiation of {sup 90}Sr/{sup 90}Y. The studied characteristics were TL curve, response reproducibility, TL response in function of the dose and fading of the information. The samples exhibited a thermoluminescent curve (TL) with two very defined peaks centered respectively in 167 and 307 C. The TL response of the samples under the action of the beta radiation after 10 cycles (thermal erased, irradiation and reading of the samples) presented a standard deviation of 3.09%. The TL response of K{sub 2}F{sub 5}: Y{sub 0.99} Tb{sub 0.01} in function of the absorbed dose of beta radiation resulted lineal in the interval of 3 mGy to 1.29 Gy. The fading of the information contained in the samples of K{sub 2}F{sub 5}: Y{sub 0.99} Tb{sub 0.01} was of 40% in the first 10 minutes, which is due to the first peak. The obtained results suggest that the TL material resulted as promissory for its possible use as thermoluminescent dosemeter of beta radiation using the second peak of its TL curve like dosimetric peak.

    Results on the synthesis process of nano metric ceramic powders of the Sr{sub 1}-xBa{sub x}Nb{sub 2}O{sub 6} compound (SBN) for two values of x (0.33 and 0.50), and two synthesis methods (Pechini and controlled coprecipitation) are presented. Parameters such as pH of solution, niobium precursor and heat treatment were varied. The phase purity of obtained powders was analysed by X-ray diffraction and their morphology by scanning electron microscopy. The effect of both synthesis methods and of the above mentioned parameters in obtaining pure phase and particle size were concluded from the characterization analysis. Pechini method (with pH = 9.7) yielded the pure phase SBN for x 0.33 and particle size of the order of 50 nm, while the controlled co-precipitation method was not possible to obtain pure phase.

    Objective: In patients with primary hyperparathyroidism, candidates for surgical intervention, the parathyroid pre-operative localization is of fundamental importance in planning the appropriate surgical approach. Materials and methods: The additional acquisition of SPECT and Technetium-99m images, during parathyroid scintigraphy with Sestamibi, is not common practice. Usually, only planar image acquisition, 15 minutes prior and 2 hours after radiopharmaceutical administration, is performed. Results: in our experience, the complete protocol in parathyroid scintigraphy increases the accuracy of pre-operative parathyroid localization. Conclusion: the complete utilization of all available nuclear medicine methods (SPECT e {sup 99m}Tc) and image interpretation in a multidisciplinary context can improve the accuracy of parathyroid scintigraphy.

    The objectives were to benchmark and monitor the fracture healing of femoral osteotomy in rabbits after fixation with dynamic compression plate and bridge plate associated with intramedullary pin. Were used 14 New Zealand rabbits, four months old with mean weight of 3.5 pounds, from the Experimental Farm Professor Helio Barbosa of the Veterinary School of Minas Gerais Federal Univ. (UFMG). The animals were randomly divided into two groups (I and II). All rabbits underwent osteotomy across the middle third of right femur. In the group I was made to fix the osteotomy with the bridge plate (BP) associated with intramedullary pin, introduced the technique of minimal invasion. In group II, we used dynamic compression plate (DCP) via the conventional approach. Both groups were evaluated clinical, radiographic, histologic and scintigraphic findings. Clinical assessments were performed weekly until the 12{sup th} postoperative week and radiographic examinations were performed before, immediately after, at 15, 30, 45, 60 and 90 days. The bone scintigraphy were performed before and at 20, 50 and 90 days after surgery to monitor the bone metabolism qualitatively and quantitatively. Observed perfusion and bone healing process. After 90 days of study, there was histopathologic evaluation of the osteotomized area and the insertion of screws. In the region of the osteotomy was observed predominance of trabecular bone in group I and group II, the predominance of bone osteons, compatible with the original bone. On insertion of the screws did not differ between groups and there was cortical discontinuity, little necrosis and local hemorrhage. The two types of fixation have led to consolidation within the scheduled period, maturing in early fixation with DCP fixation compared with BP. Scintigraphy demonstrated by the indices of activity and image characteristics, the process of bone healing was significantly greater in animals undergoing early fixation with DCP. (author)

    personnelles dans l’étude de la stigmatisation lié au VIH et prōnent l’incorporation de l’existence du capital humain dans les futurs programmes de réduction de la stigmatisation du VIH. En este estudio se examinó el estigma hacia el VIH/SIDA entre proveedores de servicios chinos mediante la comparación de sus actitudes hacia las personas que viven con el VIH/SIDA con su precepción de las normas sociales relacionadas a personas que viven con el VIH/SIDA. Se seleccionaron al azar tres hospitales provinciales, cuatro de la ciudadlhospitales de la prefectura, diez hospitales del condado, 18 clinicas de salud municipales, y 54 clinicas de la aldea de Yunnan, China. Los médicos y las enfermeras fueron incluidos en la muestra de manera aleatoria y considerando la relación enfermera-médico de cada hospital o clínica. Una muestra grande de técnicos de laboratorio fue incluida en el estudio con el fin de garantizar su adecuada representación en los análisis. Un total de 1,101 proveedores de servicios participaron de manera voluntaria en una encuesta anónima, en la cual se evaluaron las caracteristicas demográficas, las actitudes individuales, asi como la percepción de las normas sociales hacia personas que viven con el VIH/SIDA, la intención de discriminación laboral, las actitudes globales de prejuicio y los conocimientos sobre el VIH/SIDA.

    Introduccion. El tratamiento de la esclerosis multiple se basa en la administracion de farmacos modificadores de la enfermedad (FAME), utilizados para frenar el curso natural de la enfermedad. Objetivo. Evaluar el grado de cumplimiento de las guias terapeuticas de la Sociedad Española de Neurologia (SEN) de 2010 por parte de los neurologos. Pacientes y metodos. Estudio observacional, retrospectivo y multicentrico de 218 pacientes adultos con esclerosis multiple de al menos cinco años de evolucion y en tratamiento con FAME. Los datos se obtuvieron de la historia clinica y se compararon con las recomendaciones de la SEN. Resultados. Segun las guias de la SEN de 2010, el 82% de los pacientes presentaba respuesta clinica adecuada, y el 18%, respuesta clinica inadecuada al FAME actual; el 94% y 92%, respectivamente, mantuvieron ese tratamiento. Los pacientes en los que la respuesta clinica inadecuada no origino un cambio del FAME actual llevaban en tratamiento mas tiempo y experimentaron con mayor frecuencia progresion de su discapacidad e incremento del numero de brotes. El 48% de los pacientes inicio tratamiento de primera linea con interferon beta-1a, administrado por via subcutanea (29%) o intramuscular (19%), seguido de interferon beta-1b y acetato de glatiramero. Algunos pacientes recibieron tratamientos de segunda linea como segunda/tercera opcion (15% y 28%, respectivamente), pero el uso de estos tratamientos (especialmente natalizumab) solo se generalizo a partir de la cuarta linea de tratamiento. Conclusiones. De acuerdo con las guias de la SEN de 2010, la mayoria de los pacientes tuvo una respuesta clinica adecuada. Un elevado porcentaje de pacientes con respuesta clinica inadecuada continuo con el tratamiento actual.

    .A presença de Instabilidade de microsatellites (IMS tem sido relatada no cancer gastrico e associada a pacientes com idade mais avançada, localização mais distal do tumor, estadios mais precoces e melhor prognostico. Relatamos neste prospectivo estudo envolvendo 24 pacientes com cancer gastrico solitario e esporadico, a incidencia de IMS, sua correlação com parametros epidemiologicos, clinicos e anatomo patológicos e o seu impacto sobre a sobrevida geral e livre de doença. PACIENTES E MÉTODOS: Todos os pacientes haviam sido tratados com cirurgia radical. Fragmentos de tecido normal e tumoral eram extraidos das peças e armazenados a -80ºC antes da extração e purificação DNA. Realizava-se então a amplificação com PCR utilizando marcadores específicos de microsatelites. Os tumores que apresentavam produtos de amplificação anormais foram considerados positivos para IMS. RESULTADOS: Cinco pacientes (21% apresentaram Instabilidade de microsatelites (IMS+ com pelo menos um marcador (primer No grupo de pacientes com adenocarcinomas gástricos do tipo histológico de Lauren, três apresentavam IMS (23% enquanto no grupo portador de cancar gástrico difuso, dois pacientes mostraram IMS (19%.. Embora haja uma tendência dos pacientes IMS+ apresentarem tumores de localização mais proximal, estadios mais precoces e ausência de metástases linfonodais, não se observou diferenças estatisticamente significativas (p > 0,1. A comparação entre as taxas de sobrevida geral e livre de doença não mostrou significância estatistica (p > 0,1. CONCLUSÕES: IMS é um evento frequente na carcinogese gástrica e pode estar associado a caracteristicas clinicas e anátomo-patológicas do câncer gástrico.

    Introduccion. Existe la creencia del abuso de las tecnicas de neuroimagen en pacientes con cefalea en nuestro medio. Objetivo. Analizar el consumo de tecnicas de neuroimagen, y fundamentalmente de la tomografia computarizada (TC), ya que es de acceso libre en nuestra area, en la practica clinica habitual en pacientes con migraña cronica (MC). Pacientes y metodos. Se revisan las historias clinicas de una serie de mujeres consecutivas diagnosticadas en nuestra consulta de cefaleas de MC. Se recogieron datos acerca de la realizacion de tecnicas de neuroimagen a todos niveles (urgencias, consultas y pacientes ingresados). Resultados. Se incluyeron 139 mujeres con MC. Un total de 106 pacientes (76%) tenia al menos una TC de craneo y 28 (20%) dos o mas estudios de TC de craneo. En seis de estas pacientes (21%) existia justificacion clinica para la repeticion del estudio, pero no en las 22 (79%) restantes. Ya en nuestro servicio se solicito resonancia magnetica (RM) a 59 pacientes (42%). En 43 (73%), la RM fue normal; en nueve (15%) puso de manifiesto lesiones inespecificas en la sustancia blanca; y en siete (11%) fue patologica, si bien en ninguno de estos casos habia relacion directa entre la lesion de la RM y la clinica de MC. En 15 pacientes con MC (11%) no se habia solicitado ningun estudio de neuroimagen. Conclusiones. En contra de nuestra hipotesis inicial, no encontramos un abuso de las tecnicas de neuroimagen en pacientes con MC en nuestra area de salud.

    INVESTIGACION CLINICA was founded by the initiative of Américo Negrette, who became its first editor, and it has been published uninterruptedly since July 1960, with a quarterly frequency. The first issues consisted mainly of a collection of reviews of seminars held at the now called Instituto de Investigaciones Clínicas "Dr. Américo Negrette", Facultad de Medicina, Universidad del Zulia, its publisher. Very soon, original research results from this institution were included in the novel journal. In the 60's, papers on results obtained during the outbreaks of Venezuelan Equine Encephalitis present in the area, were prominent. Originally, the journal published 3-4 papers, but due to the increased number of contributions, in 2001, its format changed from 1/16 to 1/8, and now each number includes 11 original articles. Currently, INVESTIGACION CLINICA publishes 44 papers a year, in Spanish or English on different biomedical topics, from contributors all around the world. Progressively it has been included in different renowned indexes, such as PubMed/MEDLINE, Science Citation Index Expanded, Excerpta Medica, Tropical Diseases Bulletin, Copernicus, Scopus, Periodica, and several others. Besides, it can be found in open access through www.Scielo.org.ve, www.freemedicaljournals.com and in our new Web page: https://sites. google.com/site/revistainvestigacionesclinicas/home. Most papers published in INVESTIGACION CLINICA have been cited in the regional or foreign literature accumulating more than 1200 citations by now. For this particular issue, to celebrate the 50th anniversary of INVESTIGACION CLINICA, we have invited some of our more recent referees or authors to contribute with Reviews in their respective areas of expertise.

    Introduccion. La estimacion de sintomas cotidianos de disfuncion frontal se considera imprescindible para aportar validez ecologica a las evaluaciones neuropsicologicas. Los cuestionarios disponibles se construyeron para estimar problemas ejecutivos en la vida diaria en poblaciones con daño neurologico. Se requieren instrumentos enfocados a medir estos comportamientos en la poblacion general o en poblaciones clinicas con fallos leves o moderados. Objetivo. Estudiar la validez factorial y encontrar indicios de validez concurrente de la version abreviada del inventario de sintomas prefrontales. Sujetos y metodos. Se obtuvieron tres muestras: la primera, a traves de Internet (n = 504); la segunda, en poblacion no clinica mediante lapiz y papel (n = 1.257), y la tercera, de pacientes en tratamiento por adiccion a sustancias (n = 602). Se utilizo un metodo de analisis factorial sin restricciones sobre la primera muestra y los resultados se sometieron a analisis factorial confirmatorio sobre las otras dos muestras. Resultados. La estructura de tres factores encontrada se confirmo con excelentes indicadores de ajuste en las otras dos muestras. Se hallaron indicios de validez concurrente con pruebas de calidad de vida y salud mental. Conclusiones. Se propone un cuestionario breve para la deteccion de fallos de origen prefrontal en la vida diaria, que mejora las cualidades psicometricas de tests similares, pero orientados a patologias neurologicas graves. La estabilidad estructural de la prueba garantiza la utilidad en la poblacion general, para la deteccion precoz del deterioro cognitivo, y en poblaciones clinicas con deterioro leve o moderado. Se proponen baremos para la interpretacion de resultados.

  19. Using a voucher system to extend health services to migrant farmworkers.

    Science.gov (United States)

    Slesinger, D P; Ofstead, C

    1996-01-01

    FAMILY HEALTH/LA CLINICA de los Campesinos, Inc., is a federally funded migrant health clinic in the heart of Wisconsin's farmland that has offered outpatient health care since 1973 and an accompanying "voucher" program since 1988. The charges for outpatient care are based on the ability to pay. The clinic issues vouchers not only to migrant workers living and working in remote parts of the State but also to patients needing services the clinic does not offer. Between 1 April 1992 and 30 March 1993, 677 participants submitted 1,794 vouchers that provided for $83,833 in partial health care payments. La Clinica paid a median amount of $22 for each voucher, its reimbursement value ranging from $1 to $979. Hospitals received the highest median payment and pharmacies the lowest. Voucher payments generally covered 60% of the bill, but dentists commanded a higher percentage(70%) and clinics and medical groups a lower one (42%). Most vouchers paid for procedures and services La Clinica could not provide. This program shows how a health care provider in one location, with a patient population scattered throughout a sizeable geographic area, can coordinate services not offered at its facility. With the national spotlight on health care reform, the concept of vouchers for people in outlying or underserved regions deserves further investigation.

    Introduccion. El sindrome antifosfolipido (SAF) es un trastorno autoinmune que determina un estado de hipercoagulabilidad caracterizado por eventos tromboticos, abortos de repeticion y la presencia de anticuerpos antifosfolipido. Puede presentarse de manera aislada (SAF primario) o asociado a lupus eritematoso sistemico u otras enfermedades autoinmunes (SAF secundario). Las manifestaciones neuropsiquiatricas del SAF incluyen jaqueca, epilepsia, corea, demencia y psicosis. Se realiza una revision bibliografica de la sintomatologia neuropsiquiatrica en general y psicotica en particular de los pacientes afectos de SAF. Caso clinico. Mujer de 23 años afecta de un SAF primario que comenzo con manifestaciones clinicas unicamente neuropsiquiatricas consistentes en sintomatologia psicotica (dos episodios de clinica delirante) y movimientos anormales coreiformes y hemibalisticos que inicialmente se interpretaron como clinica conversiva. Conclusiones. Se discute la patogenesis de la sintomatologia motora y psicotica. La etiologia de los sintomas neuropsiquiatricos todavia no se conoce con claridad, pero la trombosis de pequeños vasos en el cerebro podria explicar parte de los sintomas. Asimismo, se revisa el papel que la medicacion antipsicotica y antitrombotica tiene para estos pacientes. En la actualidad, nuestra paciente se mantiene asintomatica sin necesidad de terapia antipsicotica y recibe tratamiento unicamente con un agente antiagregante y otro antipaludico.

The stent is implanted through a small corneal incision under gonioscopic control. Intraocular pressure control was reported in cultured human anterior segment.Design: Observational case report.Methods: We report the case of a patient who was implanted and followed-up for 1 year at the Dipartimento di Fisiopatologia Clinica. The main outcome measures were intraocular pressure and visual field.Results: The patient’s intraocular pressure was controlled with topical beta-blockers for 6 months and without therapy for 6 months. Two diurnal curves demonstrated achievement of target pressure during the day. The 1-year visual field was unchanged.Conclusions: We are not aware of previous reports of trabecular stent implantation in pseudophakic patients. The trabecular stent had minimal peri-operative morbidity. Identification of the implantation site is challenging and reduction of efficacy over time may occur.Keywords: stent, trabecular bypass, intraocular pressure, glaucoma

    Introduccion. La aparicion de un nistagmo vertical inferior clasicamente obliga a descartar una patologia vascular o de la union craneocervical mediante resonancia magnetica (RM). Estudios recientes demuestran una baja rentabilidad de esta prueba, ya que sugieren que este signo oculomotor puede tener una causa vestibular periferica, sobre todo cuando el paciente presenta un vertigo posicional paroxistico benigno (VPPB) del canal semicircular superior. Objetivo. Comprobar la rentabilidad de la RM en una poblacion de pacientes con nistagmo de posicion vertical inferior. Pacientes y metodos. Estudio retrospectivo de 42 pacientes consecutivos a los que se les realizo una historia clinica, exploracion fisica, y pruebas vestibulares caloricas y rotatorias. A todos ellos se les practico una RM craneal y cervical. Resultados. El 52% de los pacientes con nistagmo de posicion vertical inferior presentaba una clinica y exploracion fisica compatibles con VPPB del canal semicircular superior. La RM fue normal en un 67%, un 26% mostraba datos de espondilopatia y un 5% de microangiopatia cerebral no relacionados con la clinica del paciente. La prevalencia de malformacion de Arnold-Chiari de tipo I fue de un 9% en la poblacion estudiada, sin que nadie tuviera un antecedente reciente de VPPB. Los resultados obtenidos en las pruebas complementarias vestibulares no aportaron informacion adicional para llegar a un diagnostico etiologico. Conclusion. En los pacientes con un VPPB, la RM craneal y las pruebas vestibulares tienen una baja rentabilidad diagnostica, y se debe evaluar la necesidad real de esta prueba con el contexto clinico.

    Introduccion. La paquimeningitis hipertrofica idiopatica es una enfermedad fibroinflamatoria de la duramadre. Su diagnostico requiere la exclusion de enfermedades infecciosas, tumorales y otras enfermedades inflamatorias. En los ultimos años se han descrito nuevas entidades que pueden presentarse con paquimeningitis hipertrofica: la enfermedad relacionada con IgG4 y la paquimeningitis MPO-ANCA+ como forma de vasculitis limitada al sistema nervioso central. Caso clinico. Varon de 64 años con cefalea y cervicalgia de predominio nocturno y clinica de compresion medular. Tras el diagnostico de paquimeningitis hipertrofica craneocervical facilitado por el estudio de resonancia magnetica, se realizo un estudio etiologico. Se descartaron enfermedades infecciosas y tumorales. La clinica no mostraba afectacion sistemica y en la analitica presentaba IgG4 elevada y MPO-ANCA+. Tras tratamiento con corticoides presento una rapida mejoria de la clinica. Conclusiones. La enfermedad relacionada con IgG4 y la vasculitis asociada a MPO-ANCA limitada al sistema nervioso central pueden representar un alto porcentaje de las paquimeningitis hipertroficas que se consideraban idiopaticas, y su diagnostico requiere biopsia y estudio histologico.

    Introduccion. La enfermedad relacionada con IgG4 es una entidad clinica multisistemica recientemente descrita y que se presenta con diferentes manifestaciones clinicas. Los organos que estan afectados con mayor frecuencia son el pancreas, la via biliar y las glandulas salivales, y es menos frecuente la afeccion del sistema nervioso central. Caso clinico. Mujer de 33 años con alteraciones cognitivas, alucinaciones, cefalea, sindrome convulsivo, sinusitis maxilar con afeccion osea y evidencia de paquimeningitis y panhipopituitarismo, con biopsia meningea que confirmo una enfermedad relacionada con IgG4, tras haberse descartado causas secundarias. Se inicio tratamiento con glucocorticoides y azatioprina, sin recaidas despues de 12 meses de seguimiento. Conclusiones. Se debe considerar el diagnostico de enfermedad relacionada con IgG4 en casos de paquimeningitis hipertrofica e hipofisitis, incluso sin que se acompañen de otras manifestaciones sistemicas, siempre que se hayan descartado otras causas mas frecuentes. El tratamiento de eleccion son los glucocorticoides, y puede ser necesario añadir otro inmunosupresor como ahorrador de esteroides y para evitar las recaidas. Se necesitan estudios prospectivos para evaluar las diferentes manifestaciones clinicas y paraclinicas y establecer los resultados del tratamiento a largo plazo.

    Introduccion. La epilepsia es una enfermedad cronica que implica un seguimiento periodico del paciente a largo plazo, lo que supone un aumento del numero de pacientes visitados con el tiempo y, por tanto, un coste al sistema sanitario. Objetivo. Determinar los factores implicados en el tiempo para la siguiente visita de un paciente epileptico. Pacientes y metodos. Seleccion de pacientes durante un ano que acuden consecutivamente a consulta de epilepsia de nuestro hospital. Se analiza su situacion clinica y relacion con el consejo medico dado, y los factores implicados en el tiempo transcurrido hasta la siguiente visita mediante modelos econometricos predictivos. Resultados. Existe una clara asociacion entre la situacion clinica del paciente y la modificacion del tratamiento propuesta por el neurologo en la visita anterior. Los factores implicados en el tiempo hasta la siguiente visita fueron frecuencia de crisis, efectos adversos medicamentosos, sobre todo los que afectan a la cognicion, y consejo medico al paciente. No resultaron significativos la politerapia, los trastornos psicoafectivos ni la situacion social del paciente. Conclusiones. El seguimiento en una consulta especifica de epilepsia mejora la situacion del paciente. Se trata del primer analisis de demanda asistencial en pacientes con epilepsia realizado mediante metodos econometricos y desde una perspectiva mixta medico-paciente. Dado que los factores que determinan el tiempo para la siguiente visita son modificables, podria disminuir el numero de visitas al ano, mejorando la situacion clinica de los pacientes. Proponemos una mayor duracion por visita para poder incidir en ello y reducir costes a largo plazo.

    Full Text Available La causa genética del pseudohermafroditismo no está bien dilucidada, sin embargo se han reportado distintos casos de pseudohermafroditas masculinos los cuales en la mayoría de los casos se han tratado de explicar por efectos hormonales sobre las gónadas en formación durante el desarrollo embrionario. Además se ha explorado poco la relación de este fenotipo con la constitución genómica de los organismos que presentan la disfunción sexual. En el presente trabajo se encontró una fuerte relación entre el quimerismo cromosómico XX/XY y el fenotipo pseudohermafrodita masculino exhibido por dos ejemplares de porcinos Landrace X Largewhite similar a lo encontrado en freemartinismo de bovinos.

    Full Text Available En la menopausia la mujer se ve afectada por múltiples cambios hormonales que tienen como resultado, en algunos casos, trastornos sistémicos, entre los que destaca la osteoporosis (debida a una pérdida de masa ósea generalizada en el organismo. En el presente trabajo se revisa el papel que la menopausia (y la osteoporosis puede tener contribuyendo a la pérdida de masa ósea alveolar y a una alteración en el periodonto que pueda dar lugar a una pérdida de inserción periodontal. Estudiados el papel de la osteoporosis "per se", del nivel de calcio, de las alteraciones hormonales y de las alteraciones en los mediadores de la inflamación (interleukinas, se concluye que si bien parece existir cierta relación entre estos factores y el desarrollo de problemas periodontales, hoy día no se tiene datos suficientes para extraer conclusiones definitivas, por lo que se requieren más estudios sobre el tema.Hormonal changes in menopausal women frecquently develops many systemic alterations such as osteoporosis. In the present paper, menopause and its role in the development of periodontal disease and periodontal attachment loss is reviewed. Looking at the particular role of osteoporosis and calcium, hormonal, and interleukines levels in menopausal women, the relationship between periodontal disease and these factors seems to be stablished, but to improve the knowledge about this important situation, more studies should be developed in the future.

    Full Text Available Es bien conocida la existencia de diferencias en la actividad eléctrica cardíaca asociadas al sexo. Si bien estas diferencias habitualmente se relacionan al efecto de la madurez y de las hormonas sexuales gonadales, todavía existen controversias al respecto. El objetivo de este trabajo fue evaluar el efecto que la madurez sexual y la castración producen sobre los distintos parámetros del electrocardiograma de superficie y de la duración de los potenciales de acción (DPA. Se utilizaron conejos jóvenes (menores de un mes de edad y adultos (mayores de seis meses de edad. Las diferencias obtenidas en las hembras se observan en la repolarización tardía, mientras que en los machos ocurren en la repolarización temprana. Existiría una relación entre las diferencias observadas en la duración desde el pico máximo hasta el fin de la onda T (Tpf y las observadas en la DPA al 90% de la repolarización (DPA90 en las hembras, mientras que en los machos la relación existe entre la duración desde el punto J hasta el pico máximo de la onda T (JTp y la DPA al 30 y 50% de la repolarización (DPA30 y DPA50. Si bien existen diferencias que podrían ser debidas a factores hormonales otras serían debidas a factores no hormonales.

    Introduccion. Las evoluciones atipicas de la epilepsia rolandica son parte de un espectro clinico de fenotipos variables, idiopaticos, dependientes de la edad y con una predisposicion geneticamente determinada. Objetivo. Estudiar las caracteristicas electroclinicas sugestivas de una evolucion atipica en la epilepsia rolandica. Pacientes y metodos. Se realizo una busqueda retrospectiva de 133 niños diagnosticados de epilepsia focal benigna atipica (EFBA), sindrome de Landau-Kleffner y epilepsia de punta-onda continua durante el sueño (POCS). Se seleccionaron nueve pacientes que, en el trascurso de su epilepsia rolandica, presentaron un cuadro clinico atipico y un patron electroencefalografico (EEG) de estado epileptico electrico durante el sueño (ESES). Resultados. El inicio de la epilepsia rolandica fue, en promedio, a los 5 años. Los pacientes presentaron un empeoramiento clinico y del EEG año y medio mas tarde en promedio. En tres pacientes se observaron caracteristicas de EFBA, y en seis, de POCS. No se encontraron casos de sindrome de Landau-Kleffner. El EEG en vigilia mostro una focalidad centrotemporal izquierda en seis pacientes, y derecha, en tres. Todos los pacientes presentaron un ESES en el EEG de sueño. En tres de ellos se observo un patron atipico de ESES regional. Ademas, se detectaron alteraciones cognitivas y conductuales por deficits en areas especificas del aprendizaje, como lenguaje, memoria, atencion e inquietud. Conclusiones. El inicio precoz de la epilepsia rolandica, la aparicion de nuevas crisis con un incremento en su frecuencia y una focalidad frontocentrotemporal en el EEG, que aumenta en frecuencia, tanto en vigilia como en sueño, son caracteristicas electroclinicas sugerentes de una evolucion atipica.
