    In this work are presented some results of the application of energy diagnoses to small companies. These diagnoses use the methodology developed by the Department of Energy of the United States of America and are performed by advanced students of engineering and university professors. The results of four energy diagnoses applied to companies of different branches are presented. In the studies the energy saving alternatives are evaluated, as well as their economic impact and their economic viability. The annual energy saving according to the company goes from 25,600 to 596,000 MJ (from 1.2 to 10.5%), which means a saving from $5,300 to $165,000 Mexican Currency (1.43 to 9.27%). The simple rate of return goes of 0.5 to 9.3 years. From the work it is concluded that the application of that methodology of energy diagnoses in Mexico is very feasible, since with very low costs opportunities of energy savings are identified and evaluated for this section of companies that traditionally have not been taken care of by the official programs and allows them to give launch to a solid program of energy improvement. [Spanish] En este trabajo se presentan algunos resultados de la aplicacion de diagnosticos energeticos a pequenas empresas.

    In recent years, the indoor air quality (IAQ) in work spaces have acquired special importance. Health symptoms refer to a productivity and economic loss. IAQ health symptoms associated with acute discomfort that improve while away from work. More common, however, are apparent outbreaks of illness within work spaces in which neither environmental causes non recognized diseases can be identified. Usually reported within the last years, these events are often called sick building syndrome. To determine a sick building diagnosis and treatment, it is necessary to plan methodology based on environment comfort, habitability, energy efficiency use and nature preservation. Hereby it is presented a methodology to determine a sick building diagnosis and treatment which was applied in Superior Court of Justice building (Tribunales Primero y Segundo del Decimocuarto Circuito del Poder Judicial de la Federacion), where employees have expressed diseases as sleepiness, cold and difficulty breathing. [Spanish] En los ultimos anos, la calidad del aire en el ambiente de trabajo ha adquirido especial interes debido a la importancia que representa para el bienestar, eficiencia y productividad de los empleados. Los edificios carentes de esa calidad del aire ocasionan trastornos de salud relacionados con la falta de confort que prevalece en el ambiente de trabajo, es comun encontrar en los empleados que alli laboran, brotes de sintomas como dolores de cabeza, letargo y resfriados, entre otros. Usualmente encontrados en los ultimos anos en ambientes de oficinas a estos sintomas se les llama sindrome del edificio enfermo. Para lograr el diagnostico y tratamiento de un edificio enfermo es necesario plantear una metodologia basada en criterios de confort ambiental, habitabilidad, uso eficiente de la energia y preservacion del medio ambiente. En este trabajo presentamos una metodologia para el diagnostico y tratamiento de edificios con ese sindrome y presentamos un estudio de casos de los

    o confiabilidad. De esta manera, siendo la energia nuclear la unica alternativa viable para sustituir la quema de combustibles fosiles en plantas termoelectricas, con antecedentes como el accidente de Three Mile Island en 1979 o el desastre de Chernobil en 1986, han llevado a no despreciar los riesgos relacionados. Lo cual complica su manejo y en consecuencia ha limitado la proliferacion de mas centrales nucleares. Bajo esta realidad, la problematica se concentra en dos tares: aumentar el rendimiento de las plantas termoelectricas y reducir la emision de contaminantes, tanto gases como liquidos. Por todo esto, y en cumplimiento con los valores expresados en la mision y vision del Instituto de Investigaciones Electrica (IIE), se ha seleccionado desarrollar una herramienta de apoyo para el estudio del estado de equipos rotativos remotos. Para ello, tomando como base la experiencia del IIE en el diagnostico de turbinas de vapor, se ha desarrollado una plataforma capaz de determinar la presencia de fallas a traves del modelado de la turbina y sus elementos, se representa el comportamiento esperado y, mediante la transformacion de las senales recolectadas del sistema, se calcula el comportamiento real del equipo. Con ambos resultados se procede a aplicar una tecnica de diagnostico que permita detectar las desviaciones e inferir los desperfectos existentes. Buscando mejorar la certeza y calidad de los resultados del analisis, como complemento, se ejecuta revision de las reglas de diagnostico, con base en el registro historico de diagnosis realizada y empleando un algoritmo genetico para la inclusion de reglas nuevas, las cuales se evaluan como candidatas para la mejora del producto. Este documento representa los esfuerzos de mas de un ano en el area de diagnostico, en busca de la adecuada arquitectura para una infraestructura de diagnostico remoto que permita la deteccion de fallas en centrales con turbina de vapor. El principal reto de crear esta infraestructura es la

    The importance that has to confirm the presence or absence of the chromosome Philadelphia in the diagnostic and follow up of the patient affected with chronic myeloid leukemia and other leukemia. It is considered necessary to implement the molecular diagnostic in Costa Rica. They studied 32 patient affected by Chronic Myeloid Leukemia, 7 by other Myeloproliferative Chronic Disorders and 2 by Myelodysplastic Syndrome. It utilized the sound Trans probe-1 (Oncogene Science, Inc), which was marked with radioactivity ({sup 32}P) or chemiluminescence (digoxigenin). Of the 32 cases affected by L mc, in 28 it was possible to carry out the molecular analysis detecting the characteristic translocation of the chromosome Philadelphia among the Mbcr/c-ABL genes in 21 (75%) of the patients, in 7 (25%) the rearrangement was not found. In seven of the nine affected by other sufferings it was possible to obtain results, 3 that turned out to be positive for the rearrangement among Mbcr/c-ABL and 4 normal. In all the cases, they obtained results marking the sound with radioactivity. However, they tested the marks with digoxigenin in seven of the patients, as an methodological alternative for the laboratories that lacks the requirements to work with radiation. The results obtained were identical. (S.

    es uno de los metodos mas utiles para el estudio de las alteraciones de.la circulacion pulmonar y para el diagnostico de embolias e infartcs. Sin embargo su utilizacion en diagnostico tumoral apenas si ha pasado de algunos ensayos. Los autores han centrado su atencion en el estudio, mediante gammagrafia, de pacientes con tumores de pulmon primitivos y secundarios a otras localizaciones, encontrando que segun el tipo de tumor el patron de distribucion del trazador es radicalmente distinto. En los tumores metastasicos la repercusion de las lesiones en la gammagraffa es pequena y depende exclusivamente del volumen de la zona de condensacion. Los nodulos tumorales se comportan exclusivamente como zonas inactivas dentro de una masa de parenquima funcional activo y su influencia en la imagen gammagrafica depende exclusivamente del tamano de la zona tumoral y de la cantidad de parenquima sano que se interponga entre ella y el detector. En los tumores pulmonares primitivos y muy especialmente en los localizados en la zona hiliar, lesiones relativamente pequenas originan defectos de captacion amplias zonas del pulmon, que pueden afectar a varios segmentos, a un lobulo e incluso a la totalidad del pulmon. Esta disminucion de captacion no puede explicarse exclusivamente por la imagen tumoral, ni por las zonas de atelectasia asociadas, sino que debe ser motivada por una modificacion profunda de la hemodinamica del puimon afecto. Varios tipos de fenomenos asociados a la progresion tumoral pueden motivar alteraciones vasculares que afecten hasta la periferia del pulmon: la alteracion del regimen ventilatorio con disminucion de la tension de oxigeno que da lugar a una modificacion de las condiciones hemodinamicas; la hipertension pulmonar por compresion de las venas pulmonares de menor resistencia que las arterias; y el estimulo nervioso directo por irritacion de los plexos bronquiales por el crecimiento del tumor y los fenomenos reactivos asociados.

    The accuracy of radiological diagnosis of Apical Periodontitis (AP) is reported between examiners with differents levels of clinical experience using panoramic radiographs. 1032 teeth in 41 panoramic radiographs have been diagnosed. The evaluation of the x-rays and radiological diagnosis is performed by three independent dentists for AP to each tooth. The teeth have presented without radiological signs of AP in 96.6%. The number of teeth classified with an uncertain diagnosis of AP at the has been inversely proportional to the number of years of experience of the examiner. The examiner A has been used as a reference and compared the diagnoses of other examiners.The percentage agreement for all teeth was 95% for examiner B and 94% for examiner C. Kappa for all has been of 0.44 for examiner B and 0.43 for examiner C. The different categories were analyzed separately, the inferior teeth and the anterior teeth have obtained the best results. The level of clinical experience of the examiner has been indifferent in the diagnosis of AP in panoramic radiographs; however, it is important experience in the number of radiographs extras that will be needed to give a radiological diagnosis definitive. The panoramic radiographs were reliable diagnostic tools for AP.

    To maintain the efficiency values, power and unit thermal consumption of the electrical generation units near the design levels, has been always one of the objectives of the operation and maintenance personnel of the power plants of the Comision Federal de Electricidad (CFE). A way to obtain this objective is through the systematic analysis of the equipment operating conditions and of the diagnosis of the deviations causes of the normal operation way. The Gerencia de Operacion de Maquinaria (Management of Turbo-Machinery) through projects contracted with the Unidad de Investigacion y Desarrollo (Unit of Investigation and Development) of the CFE has made the thermal evaluation of different generation units. These evaluations have allowed to identify which internal components are causing the deviations and to improve the planning of the maintenance activities required to bring back the unit to its best working conditions. In this article the methodology for the online thermal evaluation of the steam turbines and its heat transfer auxiliary equipment is described -water condenser and heaters- and some of the obtained results are also presented. [Spanish] Mantener cercanos a los niveles de diseno los valores de eficiencia, potencia y consumo termico unitario de las unidades de generacion electrica ha sido siempre uno de los objetivos del personal de operacion y mantenimiento de las plantas de la Comision Federal de Electricidad (CFE).

    The European Union Council Directive 97/43/Euratom of 30 June 1997 on health protection of individuals against the dangers of ionizing radiation in relation to medical exposure has been partially transposed to the Spanish national law by the Real Decreto 1976/1999, which establishes the quality criteria in Diagnostic Radiology. A key instrument in this legal regulation is the so-called Quality Assurance Program (QAP) which has to be implemented in each Diagnostic Radiology unit. The Spanish Breast Imaging Diagnostic Society (Sociedad Espanola de Diagnostico por Imagen de la Mama, SEDIM) has proposed a reference QAP to be used as a guide in all the mammography units in the country. Its main issues are displayed in the present paper. The SEDIM QAP includes some items related to justification and optimization of mammography exams as well as a proposal for the assignment of functions and responsibilities. A guide for the image and technical parameters quality evaluation is also included. Some keys on equipment acquisition, maintenance and on continuing education and information management can also be found in that document. (author)

    tareas mas afectada por esta situacion es la operacion de los sistemas electricos frente a la presencia de fallas, donde la primera labor a realizar por parte del personal de operacion de la red es la pronta ubicacion del lugar de falla dentro del sistema. En el presente trabajo se aborda el problema del diagnostico de ubicacion de fallas electricas en sistemas de potencia, desde la perspectiva de los operadores de los centros de control de energia de una empresa electrica. El objetivo de este trabajo de tesis es describir una metodologia de analisis de operacion de protecciones como base para el desarrollo de un sistema de diagnostico de ubicacion de fallas, que permita estimar los posibles lugares de falla dentro del sistema asi como una justificacion de la operacion de las protecciones ante un disturbio como apoyo a los operadores de los Centros de Control de Energia. La metodologia esta disenada para utilizar distintos tipos de informacion, discreta, continua y controles. Sin embargo, en el desarrollo de la presente etapa de la metodologia propuesta se hace uso exclusivamente de la informacion de tipo discreta de los estados de interruptores y operacion de relevadores, asi como de la conectividad de los elementos de la red. La metodologia de analisis consiste en determinar el grupo de elementos donde pudo haber ocurrido la falla, utilizando las zonas de cobertura de las protecciones asociadas a los interruptores operados. Posteriormente, estas alternativas de falla se ordenan en forma descendentes de posibilidad utilizando indices de clasificacion y analisis basados en logica difusa.

    In an electrical system, the substations primary equipment is integrated by the power transformers, the instrument transformers, the breakers and the interconnection circuits (energy cables). At the present time, the described primary equipment has been integrated in an arrangement denominated encapsulated substation that presents dimensional and aesthetic advantages in the conventional substations. Nevertheless, the isolation involved in this type of substations means new challenges when carrying out its diagnosis in a planned way or after the appearance of a fault. In this sense, the insulating and electromechanical system of the primary equipment of substations must be evaluated in a programmed way or be constantly monitored. This with the final purpose of detecting incipient problems that could evolve towards a fault or to the diminution of the electrical system reliability. [Spanish] En un sistema electrico, el equipo primario de subestaciones esta integrado por los transformadores de potencia, los transformadores de instrumento, los interruptores y los circuitos de interconexion (cables de energia). En la actualidad, el equipo primario descrito se ha integrado en un arreglo denominado subestacion encapsulada que presenta ventajas dimensionales y esteticas sobre las subestaciones convencionales. Sin embargo, el aislamiento involucrado en este tipo de subestaciones significa nuevos retos al efectuar su diagnostico de manera planeada o despues de presentarse una falla. En este sentido, el sistema aislante y electromecanico del equipo primario de subestaciones debe ser evaluado de manera programada o monitoreado constantemente. Ello con la finalidad de detectar problemas incipientes que pudieran evolucionar hacia una falla o la disminucion de la confiabilidad del sistema electrico.

En este articulo se presenta un esquema de diagnostico de fallas, aplicado al generador de vapor de una unidad termoelectrica, basado en tecnicas de modelado de sistemas dinamicos mediante redes de Petri. Frente a otros metodos, el esquema ofrece mayor facilidad para su implementacion, rapidez de adaptacion ante cambios de zona de operacion y buena robustez. Una manera de reducir el efecto de las fallas en un sistema de produccion, consiste de dos pasos. El primero es diagnosticar la falla tan pronto como ocurra y subsecuentemente poner en practica acciones correctivas. El concepto de diagnostico de fallas se relaciona con la primera etapa y comprende tanto la deteccion, como la localizacion de esta. Es decir, ademas de determinar que una falla esta presente, se sabe en que componente ha ocurrido. Con base en lo anterior, es claro que un sistema de diagnostico requiere supervisar las variables que caracterizan el comportamiento de las fallas, a fin de detectarlas en el momento en que se presenten e informarlo al operador. Con esta informacion, el operador podra realizar las acciones correctivas necesarias para que la planta siga operando en la medida de lo posible.

    objetiva del diagnostico. Esto ha permitido evaluar los ensayos realizados. Para la exploracion del higado se utilizo 198Au, Rosa Bengala marcado con {sup 131}I y polivinilpirrolidona marcada tambien con {sup 131}I. Ademas de la exploracion anteroposterior, se recurrio a tecnicas especiales como la exploracion estereoscopica en dos o tres planos y al empleo combinado del {sup 198}Au y el Rosa Bengala marcado con {sup 131}I para determinar los coeficientes relativos de fijacion de estos radioisotopos en el hfgado. Los pacientes habfan sido distribuidos en ocho grupos clinicos con miras a la compilacion y evaluacion de los resultados del diagnostico. En la memoria se presenta un resumen de estos resultados. Cada grupo clfnico se analizo por separado. Por ejemplo, se detecto una lesion macroscopica en el 95% de los 65 casos de equinococosis. La radiografia solo permitio descubrir calcificaciones en el 35% de estos casos, pero tambien en el 14% de los otros casos de afecciones hepaticas. Las reacciones de Weinberg y Casoni fueron positivas en el 64% de los casos de equinococosis, pero tambien en el 22 por ciento de las otras enfermedades. En loque respecta al cancer del hfgado, se detecto una lesion macroscopica en el 44% de los casos, se obtuvo un centelleograma velado en el 30% y se observaron modificaciones morfologicas en el 29%. En dos de los 158 casos de tumores malignos, el centelleograma parecia falsamente normal, pero en el 40% de estos mismos casos los resultados obtenidos en el laboratorio fueron negativos. Con la tecnica de exploracion estereoscopica en dos o tres planos se obtuvieron datos nuevos o complementarios sobre el estado del higado en el 45% de los casos. La centelleografia se utilizo tambien para el control ulterior de los resultados. Se han hecho las siguientes observaciones: 1. Despues de una equinococotomia persiste una cicatriz caracteristica en forma de lesion macroscopica. 2. Tres meses despues del tratamiento de un absceso amebico, se produce una

    This article aims at developing a graphic proposal for multithematic diagnostic map. The research`s objective is the analysis of the legends of the maps entitled Mapa Diagnostico Geoambiental da Usina Hidreletrica de Igarapava (Geoenvironmental Diagnostic map of the Igarapava Hydroelectric Plant). The analysis emphases on identifying and solving problems resulting in non-respect of the graphic transcription laws which prejudice the map`s clarity. Upon analyzing both versions of the maps, it appeared that these problems were basically resulting from bad legibility and visualization and the inadequate use of retina`s variables in the translation of graphic density and both retinian and angular separation. Graphic density was reduced and retinian separation was improved through leading a better contrast between elements of cartographic base and the Geoenvironment Synthesis Map. The angular separation was increased by using simplified forms to better visualization of the spatial structure of the information. That aspect was laos improved by creating a series of small maps to accompany the legend. Point and line elements were represented on the same map so to not prejudice hierarchical relationship between elements. All these modifications were done without affecting information extraction of the various levels of the Geoenvironmental Synthesis (BASE MAP, VEGETATION and LAND USE, HUMAN ASPECTS, CULTURAL ASPECTS AND ENVIRONMENTAL DYNAMIC). The visualization of the document as a whole was greatly improved with respect to the original proposed format. This research is but one of the various steps to the preparation of an environmental map that aims at giving clear visibility to the thousands of words of an environmental study report.

    In this work a non-standardized method for on-line diagnostic of high capacity motors based on Ultra Wide Band (UWB) Partial Discharge (PD) measuring techniques is theoretically supported, implemented and applied. The method developed is non invasive and consist in the measurement of PD in the main motor power supply cables and its ground shields connection using a near field sensor (Rogowski coil, clamp-on type) with a bandwidth of 2 to 40 MHz. The measured signals by the sensor, are stretched electronically, digitized and fed to a conventional Partial Discharge digital detector. The UWB PD detection system used displays the output in a Pulse repetition frequency-Charge-Phase angle (N-Q-?) PD pattern. The results obtained in thirteen 2500 H.P., 13.8 kV motors performed during operating in an Oil Pumping facility are presented, including its analysis and comparison with values and PD patterns reported in literature. [Spanish] En este trabajo se presentan los fundamentos teoricos, la implementacion y aplicacion de un metodo no normalizado, para el diagnostico en linea de motores de gran capacidad, basado en la deteccion de Descargas Parciales (DP) utilizando tecnicas de medicion de Banda Ultra Ancha.

    sensores y actuadores. En la actualidad este tipo de centrales tiende a dominar el mercado de generacion electrica por medio de combustibles fosiles, debido a que son las mas eficientes, rentables, de operacion flexible y con menor impacto ambiental. En la CGCC, la turbina de vapor (TV) es una componente fundamental, ya que representa la ganancia del proceso en el sentido de que permite la generacion de energia electrica adicional al aprovechar los gases de escape de la turbina de gas. En caso de que la TV falle, la eficiencia global del proceso se reduce hasta en un 40%. Por lo anterior, en este trabajo se desarrollo un sistema de diagnostico de fallas basado en modelos, de acuerdo a la metodologia FDI (Fault Detection and Isolation) de la teoria de control, con capacidad para detectar y localizar fallas en los sensores y actuadores del turbogenerador a vapor de una CGCC. El enfoque que se utilizo emplea la redundancia analitica con el objetivo de optimizar la redundancia fisica, de manera que sea posible disminuir el costo y espacio extra que implica el utilizar dispositivos repetidos. El diseno del sistema se llevo a cabo usando el analisis estructural AE) que es una herramienta basada en la teoria de grafos y ciencias de la computacion. El AE permitio realizar: analisis de monitoreabilidad, detectabilidad y aislabilidad del proceso; y proporciono la secuencia de computo de las variables no monitoreadas (desconocidas) para obtener las relaciones de redundancia analitica. Para validar el sistema de diagnostico de fallas de la TV, se programaron los algoritmos de deteccion y localizacion de fallas en LabWindows, CVI y se integraron al simulador de la CGCC. Ademas para facilitar al usuario la visualizacion de la presencia de una falla se desarrollo una interfase grafica que indica el elemento con comportamientos anormales, ya sea sensor o actuador.

    , especialmente cuando se recurre al {sup 64}Cu (periodo: 12,8 h), que puede emplearse en enfermos ambulantes. El grado de concentracion de la sustancia radiactiva en el tumor permite determinar el tipo de este ultimo. Si se combina ese metodo con la angiografla del cerebro se puede diagnosticar aun mejor el tipo del tumor, lo que tiene suma importancia para determinar si una intervencion quirurgica esta indicada. En el estudio que se describe en la memoria los diagnosticos fueron correctos en el 75-80% de todos los casos de tumores cerebrales. Las lesiones que con mayor facilidad se reconocen debido a su gran tendencia a concentrar los isotopos son los meningiomas, los abscesos y los glioblastomas, mientras que los oligodendrogliomas y los astrocitomas, que son menos capaces de concentrar la sustancia radiactiva, resultan mas dificiles de reconocer. Un grupo de astrocitomas y casi ninguno de los tumores epidermoideos son capaces de concentrar la sustancia radiactiva asi que, en este grupo, es importante confirmar el diagnostico por angiografia del cerebro. El metodo de la exploracion positronica ha demostrado su gran utilidad para descartar la presencia de tumores en casos en que se sospecha epilepsia sintomatica; el diagnostico ha resultado correcto en el 90% de dichos casos. La combinacion de la electroencefalografia y la exploracion ha sido tan eficaz para diagnosticar como para descartar la presencia de tumores, gracias a lo cual se ha podido renunciar a la arteriografia y a la hospitalizacion del enfermo cuando los resultados han sido negativos y no se han observado sintomas clinicos. El valor de ese metodo para examinar pacientes ambulantes ha quedado, por lo tanto, claramente demostrado.

    Full Text Available Las Sigatokas negra y amarilla son enfermedades causadas por Mycosphaerella fijiensis y Mycosphaerella musicola respectivamente. Estas dos especies de hongos estrechamente relacionadas y morfológicamente similares, causan necrosis severa en las hojas de banano y plátano disminuyendo el área de tejido fotosintético y acelerando la maduración del fruto. Las enfermedades producidas por estos hongos afectan la mayoría de las áreas cultivadas de banano y plátano a nivel mundial, generando un gran problema económico y ambiental. Los síntomas que produce cada uno de estos patógenos en el cultivo son similares, por lo que su correcta identificación en campo se hace difícil. Con el fin de hacer una identificación precisa de cada uno de ellos decidimos estandarizar una prueba diagnóstica basada en la reacción en cadena de la polimerasa (PCR utilizando dos oligonucleótidos de 21 bases (MF 137 y MM 137 específicos para cada una de las especies M. fijiensis y M. musicola respectivamente.

    Full Text Available OBJETIVO : Avaliar a qualidade dos serviços de saúde de atenção básica e pronto atendimento quanto ao diagnóstico da tuberculose pulmonar. MÉTODOS : Estudo transversal, com 90 profissionais de saúde da atenção básica e 68 de pronto atendimento de Ribeirão Preto, em 2009. Foi utilizado questionário estruturado com base em um instrumento de avaliação da atenção à tuberculose. Utilizaram-se os testes Qui-quadrado e exato de Fisher (ambos com nível de significância estatística de 5% e a análise de correspondência múltipla para estimar associação entre serviço de saúde e as variáveis de estrutura e processo para o diagnóstico da tuberculose. RESULTADOS : Atenção básica esteve associada à adequada provisão de insumos e recursos humanos, bem como com a solicitação de baciloscopia de escarro. O pronto atendimento associou-se à disponibilidade de equipamento de raio-X, sobrecarga de trabalho e rotatividade de recursos humanos, deficiências na quantidade de profissionais de saúde, disponibilidade de recipiente para coleta de escarro e solicitação baciloscópica de escarro. As ações de diagnóstico permaneceram centradas no médico em ambos os serviços. CONCLUSÕES : Os serviços de pronto atendimento apresentaram fragilidades em sua estrutura para identificar os casos de tuberculose. Lacunas no processo foram identificadas em ambos os serviços de atenção básica e pronto atendimento. É necessária a qualificação dos serviços de saúde que constituem as principais portas de entrada ao sistema de saúde para atender as reformas setoriais que priorizam o diagnóstico oportuno e o controle da tuberculose.

    Full Text Available Campo Quijano está a 30 Km. de la ciudad de Salta y cuenta aproximadamente con 8300 habitantes. En el éjido urbano existen dos borateras que constituyen una fuente puntual de contaminación del aire, suelo y aguas. Se estudió la prevalencia de enfermedades respiratorias en la población urbana en el año 2005. Se trabajó con los datos de las planillas de consultas diarias externas del Hospital Francisco Herrera. Se consideraron cuatro grupos de afecciones, seleccionados por la sintomatología y su posible asociación con las emisiones gaseosas de las borateras: Rinitis; Catarro en vías aéreas superiores, Espasmos y Tos irritativa. Se estimó y comparó la prevalencia de las enfermedades por barrio con la prueba de X2 y la de los residuales ajustados de Haberman. Los espasmos y catarros en vías aéreas superiores fueron las afecciones más frecuentes en la población de Campo Quijano. En rinitis no se encontraron diferencias entre barrios. El barrio San Roque presentó las mayores prevalencias en CVAs, espasmos y tos irritativa. Barrios cercanos a las borateras presentaron prevalencias dispares, lo que podría relacionarse con características socio-culturales, sanitarias y económicas, entre otros factores de riesgo, no considerados en este diagnóstico.

Los accidentes cerebro-vasculares han originado en la tercera parte de los casos anomalias en los graficos; la mitad de los graficos anormales presenta el aspecto caracteristico de los reblandecimientos (o trombosis), lo cual permite su diagnoestico; el resta de los graficos es semejante a los graficos tumorales, siendo la unica diferencia que, en caso de accidente vascular, las anomallas desaparecen despues de algunas semanas; las dos terceras partes de estas lesiones dan un gammaencefalogram a negativo. Los aneurismas arteriales, los centros epileptoegenos no tumorales y las distintas afecciones puramente neurologicas presentan resultados normales en el 96 por ciento de los casos. La exploration del cerebro mediante albumina radiactiva puede suministrar informaciones de gran valor, no solo respecta de la existencia de una lesion neuro-quirurgica y su localizacion exacta, sino tambien respecto de su naturaleza.

    intracraneanas. Se efectuaron radioanalisis de los principales tejidos encefalicos normales, de diversos tipos de neoplasmas, de hematomas, abscesos y zonas de desmielinizacion obtenidos por biopsia. Se observe que el arsenico administrado alcanza una concentracion 30 veces mayor en los meningiomas que en el tejido normal del cerebro. El isotopo alcanza una concentracion decreciente en los otros principales tipos de tumores, a saber: neuroma acustico, glioblastoma, metastasis maligna y astrocitoma. El alto grado de absorcion arsenical del tumor persiste lo suficiente como para asegurar el buen resultado de las exploraciones repetidas un dia despues de la inyeccion. La razon de las concentraciones musculo/cerebro, 3 aproximadamente, es lo suficientemente alta como para afectar la exactitud del diagnostico en lesiones situadas por debajo del hueso temporal inferior y, especialmente, de las masas musculares de la region superior de la nuca. Por su parte, en los hematomas, abscesos y zonas de desmielinizacion, las razones respectivas son lo suficientemente elevadas como para permitir su localizacion en la mayoria de los pacientes. Los resultados en biopsias de tejidos que contenian etilendiaminotetra-acetat o de cobre arrojaron razones similares, en la medida en que las pocas muestras estudiadas permiten asegurarlo. Los meningiomas constituyen probablemente una excepcion, por cuanto en el caso del cobre el indice de absorcion es mas bajo. Basandose en el radioanalisis, tanto de la secrecion urinaria como de toda la gama de tejidos obtenibles en la autopsia, los autores calculan que luego de administrar la dosis exploradora habitual de 2,3 milicuries de arsenico-74 a un individuo de 70 kg, la radiacion total emitida por el cuerpo es del orden de 3,2 rads. El rinon recibe aproximadamente 12,7 rads y el higado 9,7 rads. Las cifras correspondientes para el cobre-64 son 0,325 rads para la totalidad del cuerpo, pero la dosis hepatica asciende a 3,2 rads porque el higado absorbe

    The utilization of radioactive sources in medicine, industry and research is associated with a probability of accidental overexposures to ionizing radiation, among which localized irradiation are the most frequent events. Moreover, between 5 and 8 % of the patients undergoing therapeutical irradiations could exhibit a higher individual radiosensitivity which could account for severe skin reactions. Localized overexposures may damage not only epidermis and dermis but also deeper connective tissue, vessels, muscles and even bones. Within the framework of a cooperation agreement between the Buenos Aires Burn Hospital and the National Board of Nuclear Regulation, a Radio pathology Committee has been established in 1997 with the purpose of carrying out a collaborative project concerning diagnosis and treatment of radiological burns. The present document particularly considers radiological burns form the point of view of their physiopathology, physical and biological dosimetry, diagnosis prognosis and treatment. It also includes basic concepts of radiation biology and radio pathology. It could be an useful tool for training medical practitioners and also a practical guidance for organizing medical response in accidental overexposures. (author)

    N. Gentner, UNSCEAR officer declared during the 11 Congress of the IRPA, that the collective dose to patients due to diagnostic radiology represents 150 times the collective dose due to occupational exposures, which can give an idea of the need to dose control in the Radiodiagnosis. The practice types involved as traditional radiography appear to be in reasonable dose, however, computerized tomography and interventional cardiology have dose levels that are a challenge for the community. According to the international conference for the patient radiation protection held in 2001, the risk would be higher for patients undergoing computerized tomography of kidney and liver. Although not normally be expected that the deterministic effects dose are exceeded, in case of multiple tests as computed tomography combined with other procedures (interventional, by example), so if you can reach levels of deterministic effects. The dose indicators are obtained from various parameters such as the radiation output from X-ray tube, the dose-area product, the dose index in computerized tomography and the dose entrance in surface. The dose indices in computerized tomography have several types of indicators. The radiation measurement output of the tubes is in turn based on different conditions and parameters. Personnel occupationally exposed also shrinks risks in proportion to that of the patients, such as interventional radiologists and cardiologists. In the diagnosis also needs to be done, and may include the development of procedures to standardize and normalize the patient dosimetry for all the techniques, implement dosimetry staff at all facilities, recommend the appropriate medical surveillance of personnel occupationally exposed to each practices, create and improve the regulatory framework, particularly in the intervention areas and hybrid images, and establish and improve the census and resources control involved in the medical applications in radiodiagnostic and interventional.

    Gastrointestinal stromal tumors (GIST) are mesenquimal tumors derived from cell precursors. They have the capacity for myogenic and neurogenic differentiation and are characterized by expression of KIT protein (tyrosine kinase growth factor). Clinically, they exhibit various biological behaviors. We present 8 cases of GIST, describing both their radiological manifestation through computerized tomography (CT) and most accepted criteria for benignity and malignancy. We also describe the response of one meta statically diagnosed tumor to tyrosine kinase inhibitor. (Author) 9 refs.

El tema ambiental es un tópico que está en boca de todos últimamente, dado que la contabilidad es una ciencia social no podría ser ajena a este, y es por eso que dentro de este trabajo se aborda la importancia que tiene la contabilidad dentro de un proceso de construcción de un nuevo esquema que vincule de una manera sistémica los problemas sociales actuales y el deterioro ambiental. La búsqueda de soluciones al problema medioambiental exige a las empresas el perfecto conocimiento del problema, conocerlo implica explicar el impacto de hoy sobre el futuro, y explicar es un concepto que considera conocer, identificar, denominar, divulgar, reportar y comunicar. Es entonces aquí donde se empieza a relacionar la ecología con la contabilidad. Llegamos así al mundo de la contabilidad medioambiental.

    This method relies on the application of an algorithm for the quantitative and statistic differentiation of a sample of cells stricken by a certain kind of pathology and a sample of healthy cells. This differentiation is made by applying the principles of fractal dimension to digital images of the cells. The algorithm was developed using the the concepts of Object- Oriented Programming, resulting in a simple code, divided in 5 distinct procedures, and a user-friendly interface. To obtain the fractal dimension of the images of the cells, the program processes the image, extracting its border, and uses it to characterize the complexity of the form of the cell in a quantitative way. In order to validate the code, it was used a digitalized image found in an article by W. Bauer, developer of an analog method. The result showed a difference of 6% between the value obtained by Bauer and the value obtained the algorithm developed in this work. (author)

    Four adult patients were diagnosed as having dural sinus thrombosis (DST) by means of magnetic resonance (MR). In the three cases of acute thrombosis, MR disclosed diffuse or segmental hyperintensity in the sinuses involved, which persisted regardless of the sequence and orientation of the plane selected. MR angiography (MRA) provided diagnostic information that proved useful in the chronic case, as well as in the two cases in which follow-up was carried out to determine the degree to which permeability was restored to the sinuses involved. MR diagnosis of DST can produce false positives and negatives, the causes of which should be known, as well as the ways to avoid them, in order to prevent diagnostic errors. MR, when applied and interpreted correctly, can be considered the first, and in many cases the only, choice as a diagnostic method in DST. (Author)

Negative appendectomies, complications and length of hospital stay in a group of 152 patients with suspected appendicitis who underwent ultrasound and CT were compared with those of 180 patients who underwent appendectomy during the same time period, but had not been selected for the first group: these patients costs for each group were calculated. In the first group, the diagnostic value of the clinical signs was also evaluated. The reliability of the clinical signs was limited, while the results with ultrasound and CT were excellent. The incidence of negative appendectomy was 9.6% in the study group and 12.2% in the control group. Moreover, there were fewer complications and a shorter hospital stay in the first group. Among men, however, the rate of negative appendectomy was lower in the control group. The cost of using ultrasound and CT in the management of appendicitis was only slightly higher than that of the control group. Although ultrasound and CT are not necessary in cases in which the probability of appendicitis is low or in men presenting clear clinical evidence, the use of these techniques is indicated in the remaining cases in which appendicitis is suspected. In children, ultrasound is the technique of choice. In all other patients, if negative results are obtained with one of the two techniques, the other should be performed. (Author) 49 refs.

    The nozzles used in high voltage electrical equipment, such as power transformers and circuit breakers, constitute the elements that present greater fault risk. On the other hand, the faults in the nozzles cause, in most of the cases catastrophic damages, that expose to risk the maintenance personnel of the plant and the peripheral equipment. With the purpose of contributing with on-line monitoring techniques that indicate the nozzles condition and allow to anticipate their possible fault, the Instituto de Investigaciones Electricas (IIE) performed for the laboratory of tests of equipment and materials (LAPEM) of Comision Federal de Electricidad (CFE), a project for the development of a system for the measurement of capacitive currents in these equipments. This system allows to determine the variation in capacitance and dielectric losses, and to determine the presence of internal partial discharges in nozzles of 115, 230 and 400 kV. With this information it is possible to determine the condition of the internal isolation of the nozzles and retire them from service before deterioration takes place that puts in danger the integrity of the equipment. The management of electrical equipment of the Instituto de Investigaciones Electricas developed for LAPEM a system that measures capacitive currents of power transformer nozzles. This system was designed with the purpose of installing it in a transformer of a 400 kV machine, in the fossil power station of Tula, Hidalgo, of the Comision Federal de Electricidad. [Spanish] Las boquillas empleadas en los equipos electricos de alta tension, como transformadores de potencia e interruptores, constituyen los elementos que presentan mayor riesgo de falla. Por otro lado, las fallas en las boquillas provocan en la mayoria de los casos danos catastroficos que ponen en riesgo al personal de mantenimiento de la planta y al equipo periferico. Con la finalidad de aportar tecnicas de monitoreo en linea que indiquen el estado de las boquillas y que permitan prever su posible falla, el Instituto de investigaciones electricas (IIE) realizo para el laboratorio de pruebas de equipos y, materiales (LAPEM) de la Comision Federal de Electricidad (CFE), un proyecto para el desarrollo de un sistema para la medicion de corrientes capacitivas en estos equipos. Este sistema permite determinar la variacion en capacitancia y perdidas dielectricas, asi como la presencia de descargas parciales internas en boquillas de 115, 230 y 400 kV. Con esta informacion es posible determinar el estado del aislamiento interno de las boquillas y retirarlas del servicio antes de que se produzca un deterioro que ponga en peligro la integridad del equipo. La gerencia de equipos electricos del Instituto de Investigaciones Electricas desarrollo para el LAPEM un sistema que mide corrientes capacitivas de boquillas de transformadores de potencia. Este sistema se diseno con el fin de instalarse en un transformador de maquina de 400 kV en la central termoelectrica de Tula, Hidalgo, de la Comision Federal de Electricidad.

    Objective: The present study was aimed at describing uncommon presentations of intraosseous hemophilic pseudotumor in imaging diagnosis. Materials and methods: Retrospective study evaluating five hemophilic pseudotumors in bones of two patients with hemophilia A. Imaging findings were consensually evaluated by two musculoskeletal radiologists. Plain radiography, computed tomography and magnetic resonance imaging studies were analyzed. Results: At contrast-enhanced computed tomography images, one of the lesions on the left thigh was visualized with heterogeneously enhanced solid areas. This finding was later confirmed by anatomopathological study. Another uncommon finding was the identification of a healthy bone portion interposed between two intraosseous pseudotumors in the humerus. And, finally, a femoral pseudotumor with extension towards soft tissues and transarticular extension, and consequential tibial and patellar involvement. Conclusion: The above described imaging findings are not frequently reported in cases of intraosseous pseudotumors in hemophilic patients. It is important that radiologists be aware of these more uncommon presentations of intraosseous pseudotumors. (author)

    In regard to verification of medical diagnosis establishments with X radiation, it is very important to the coordination between the competent authorities such as the coordination achieved between the Federal Commission for the Protection against Sanitary Risks attached to the Health Secretary and the National Commission of Nuclear Safety and Safeguards, under the Energy Secretary. The Health Secretary found a subcommittee of environmental health standards to develop the Mexican Official Standards of medical diagnosis with X-rays, with the participation of over 50 institutions and experts in Mexico. The legal framework governing the procedures for health surveillance in radiology include the Health General Law, the Internal Regulation of the Health Secretary, the Regulation of the Federal Commission for the Protection against Sanitary Risks and the Mexican Official Standard NOM-229 SSA1 -2002, {sup T}echnical requirements for the facilities, health responsibilities, technical specifications for the equipment and radiation protection in medical diagnosis establishments with X-rays{sup .} Among the participated institutions in the revision of this standard were federal government agencies, public and private sector institutions, educational institutions and professional associations. The standard establishes criteria for design, construction and facilities maintenance, technical requirements for the acquisition and operation vigilance of equipment, health requirements and patient protection. Standard observance is for establishments that use X-ray generators for its application in humans with purposes of medical diagnosis either fixed or mobile units. It also contains aspects that must be observed by owners of establishments who hold formal, responsible, own X-ray equipment and consultants with expertise in radiation protection. In the field of diagnosis radiology the Federal Commission for the Protection against Sanitary Risks, has the mission to ensure the patients health protection and occupationally exposure personnel in the medical use of ionizing radiation sources, ensuring the existence of radiation protection programs and quality, as well as protect to the general population of derivates risks of the ionizing radiation exposure.

    To describe the most pertinent echographic findings regarding systemic and renal candidiasis in high-risk neonates. Echographic findings and clinical histories of 40 neonates in the neonatal intensive care unit were retrospectively analyzed. Thirty-eight presented systemic candidiasis with renal participation, while two showed only renal candidiasis. Ultrasound scans were performed using 7.5 MHz probes. Alterations in renal echo structure, presence of echogenic material without acoustic shadowing in the excretory system (mycetoma), presence of lithiasis, pyonephrosis and associated renal malformations were all evaluated. Ten patients presented renal alterations in ultrasound scan. Six children had originally shown increased eye-catching in the renal parenchyma which was resolved after medical treatment. Four children presented renal mycetoma, and in two there were renal malformations. Both of these exhibited a profile for pyonephrosis. One patient with renal mycetoma without urological abnormalities developed a lithiasis. Surgical intervention was unnecessary in all cases. The most common echographic findings in immature high-risk low-weight patients with systemic and renal candidiasis were alterations in the eye-catching of renal parenchyma and the presence of mycetoma.

    The concern of the corrosion in buried pipes has increased with the course of time, the aging of the mechanical protection of the piping, results in defects in the coating, exposing the metal to the corrosive ground, in which the piping is lodged. If suitable levels of cathodic protection do not exist, the corrosion phenomenon in these defects is presented originating unexpected faults in the piping, increasing the costs of maintenance and repair, as well as the diminution in the safety during the operation, as much for the workers as for the communities near the installation of ducts. The technique of Direct Current Voltage Gradient (DCVG), besides locating the defects of the coating in a buried pipe (which are corrosion potential sites), determines corrosion status of the defects and its severity as far as the consumption of protection current that each of these absorbs. Nevertheless, all this information acquires a greater relevance, when it is correlated with the operating conditions of the cathodic protection systems, to be able to emit recommendations that lead to the mitigation or eradication of the corrosion problems, together with a good operation of the protection systems. [Spanish] La preocupacion por la corrosion en tuberias enterradas ha ido en aumento con el transcurso del tiempo, debido al envejecimiento de la proteccion mecanica de las tuberias, el cual da como resultado defectos en el recubrimiento, dejando expuesto el metal en suelo corrosivo, en el que se encuentra alojada la tuberia. Si no existen niveles de proteccion catodica adecuados, se propicia el fenomeno de corrosion en estos defectos, originando fallas inesperadas en las tuberias, incrementando a su vez los costos de mantenimiento y reparacion, asi como la disminucion en la seguridad durante la operacion, tanto para los trabajadores como para las comunidades cercanas a las instalaciones de ductos. La tecnica de Gradiente de Voltaje de Corriente Continua (DCVG), ademas de localizar los defectos del recubrimiento en una tuberia enterrada (los cuales son sitios potenciales de corrosion), determina el estatus de la corrosion de los defectos y la severidad en cuanto al consumo de corriente de proteccion que cada uno de estos absorbe. Sin embargo, toda esta informacion adquiere una mayor relevancia, cuando se correlaciona con las condiciones de operacion de los sistemas de proteccion catodica, para poder emitir recomendaciones que conduzcan a la mitigacion o erradicacion de los problemas de corrosion, aunados a una buena operacion de los mismos.

    An evaluation of the Diagnodent equipment (Kavo Company, Germany) for the occlusal caries detection was dane through the comparison with other conventional diagnostic techniques, such as visual inspection, intra-oral micro camera and digital X-ray. The effectiveness of the equipment in the detection of hidden caries and its viability as a diagnosis method for caries in their initial stage was also studied. Fifty eight permanent molars and premolars teeth from patients with age between 6 and 30 years were studied. The obtained results indicated that the conventional methods employed for the caries diagnosis are unable to detect the carious lesion in its initial stage. The Diagnodent equipment has this capability to detect caries presenting a flawless surface, specially the hidden caries, allowing the dentist to decide between a preventive ar a conservative procedure. The main advantage of the Diagnodent is to be an objective method, compared to the visual and radiographic ones, that are dependent on the professional interpretation. The Diagnodent is, therefore, a promising alternative as an objective and standardized diagnosis method for the final diagnostic. (author)

    In the year 2000 the first service of biological dosimetry was requested to the Instituto Nacional de Investigaciones Nucleares (ININ), and until the year 2012 have been assisted 52 cases approximately. Most of the cases correspond to workers dedicated to the industrial radiography, followed by the occupationally exposed personnel either in the hospital area or health services and the minority corresponds to individuals linked to research institutions. The incident with more serious consequences to the individual happened to workers that ingested I-131 in the year 2003. Using the biological dosimetry to estimate exposure dose by damage in the lymphocyte chromosomes of each worker has been possible to establish the exposure dose in each one of them, or also to discard the supposed exposure. The dosimetry demonstrates to be an useful tool for situations with exposure suspicion, for example when the reading of thermoluminescent dosimeter of a occupationally exposed personnel does not correspond to the event, or when the personnel forgets to carry his dosimeter, the exposure dose can be determined.

La zona está situada entre 2200 y 2550 msnm y tiene precipitaciones anuales entre 2060 y 4000 mm La topografía predominante es ondulada y los suelos de textura franco-arenosa, son ácidos y de baja fertilidad. Se trabajó mediante una encuesta inicial sobre características generales de la explotación y luego se realizó un monitoreo, durante 6 meses, sobre los parámetros productivos y reproductivos. El análisis de la información se realizó mediante estadística descriptiva. El tamaño de las fincas, predominante en la zona, es de menos de 50 hectáreas y con promedio de 42 animales, en su mayoría de raza Holstein. Los pastos predominantes son kikuyo (Pennisetun clandestinum, y en segundo lugar la falsa poa (Holcus lanalus. Un 90-100 % de las fincas utilizan fertilizante químico y hasta un 70 % de ellas, aplican porquinaza, pero solo un 40-50% utilizan encalamiento; sin embargo es necesaria mucha transferencia tecnológica acerca del manejo adecuado de pasturas. Los insectos plagas chinche (Collaria sp y lorito verde (Draeculacephala sp, causan daño grave en las praderas y se requieren alternativas viables para su control. El uso de suplementos concentrados en vacas y novillas es inadecuado y son requeridas acciones de transferencia tecnológica, relacionadas con el uso eficiente de ellos. Solamente el 24 %de los ganaderos usa inseminación artificial, pero parece ser más importante el problema alimenticio en la zona. La crianza de las terneras se realiza en base a leche, suministrando 200-400 litros en períodos entre 60 y 120 días, con muy poco uso de suplemento concentrado. La producción de leche por vaca/día está entre 10.5-12.1 litros, acorde con el programa alimenticio; siendo claro que las vacas no hacen pico de la curva, debido a desbalance nutritivo. El intervalo entre partos varía entre 396 a 461 días, siendo susceptible de mejorarse también con un mejor programa alimenticio.

    This study aimed to develop a methodology to diagnose energetically a water supply system for a irrigation system and for a city. The steps taken were: the energy quality supplied by the utility in relation to level and unbalanced of the supplied voltage; the electrical energy consumption and demand for the pumping station; the study of the electrical and hydraulic load's characteristics; the tariff and demand contracts optimization; the water storage capacity; and the working hours management. This methodology was tested and validated for the water pumping station in a town of about 70,000 inhabitants. Among the proposed actions, which saved the most, were: the sizing of pumps and motors and the optimization of tariff and demand contracts. It was noted that this methodology is simple and easy to apply and there is a great potential for saving energy up to 52%. (author)

It is most common in elderly women with a previous history of cholelithiasis. As the clinical signs are nonspecific, radiological studies are of great importance in the attempt to reach an early diagnosis, thus improving the prognosis. We present two patients with a history of cholelithiasis in whom Bouveret's syndrome was diagnosed preoperatively by different imaging techniques. (Author) 8 refs.

    In this work a study of simulation of the gamma graphic studies that are carried out in human esophagus in the Dept. of Nuclear Medicine of the 'Celestino Hernandez Robau Hospital of Santa Clara is presented. For the investigation tubular reactors were used and sting-response techniques with radioactive tracer of Technetium 99 metastable to a concentration of 1 mCi and several flows were applied. The distribution curves of residences times were obtained, those that respond to an equation of the type: Y = A + B exp (- exp((x-C)/D)) - ((x-C/D)+1). They were also carried out, optimizations studies of the doses of the radioactive to give to the patients from 1 mCi (that is the one used in studies) up to 0,5 mCi, and the influences on the obtained distributions of residence time were analyzed. It was confirmed the possibility to lower the doses with clear information of the signal. It was also carried out a simulation of the attenuation of the radiations that takes place in the patients by the interposition of tissues among the analyzed organ, and the detection equipment. It was used paraffin for tissue simulation. It was found the almost independence of the intensity of the radiations with the thickness, for the assayed doses. Lastly it was found a complex mathematical model that responds to the diagnostic curves obtained in these studies, being correlated the coefficients of the pattern with the most important physical parameters of the system, giving it a practical and useful value, all time that the error among the values that this it predicts and the experimental ones do not surpass of 5%.

    The Clean Development Mechanism (CDM) contributes to sustainability and to sustainable development in those countries where CDM projects are developed and helps the countries from Annex I to achieve their reduction targets to Greenhouse Gases. This paper presents a proposal of a social and environmental sustainability diagnosis making use of a tool called Social and Environmental Evaluation Matrix - MADSA{sup R}. Its purpose is to establish and measure appropriate sustainable indicators to evaluate projects to ensure development benefits of CDM projects in host countries in consistency with Annex I countries developmental goals. MADSA{sup R} methodology allows a definition of a social and environmental baseline to MDL projects, and provides information to any interested group of people, from stockholders to local community; showing its results. It allows a greater clients', stockholders' and investor's trust as it measures the development so it makes possible the diagnosis and the comparison between all phases of the project. It also contributes to a continuous improvement through the participation of benefit groups in the diagnosis. Besides being an evaluation method and a management tool, this proposal looks for being a reference as an indicator pattern that evaluates the sustainable social and environmental development of CDM projects.

  3. Molecular markers derived from bombesin for tumor diagnosis by SPECT and PET; Marcadores moleculares derivados da bombesina para diagnostico de tumores por SPECT e PET

    A high number of molecules have already been identified to have high affinity to some receptors overexpressed on tumour cells and the radiolabelling of those molecules offers the possibility of new compounds for tumour diagnosis and therapy by nuclear medicine. Among of those molecules, bombesin (BBN) has become focus of interest, as its BB{sub 2} receptors are known to be overexpressed in prostate, breast, colon, pancreatic and lung tumour, as long as glioblastomas and neuroblastomas. BBN agonists and antagonists have already been described for this purpose and promising results were obtained in preclinical studies. However, most of them exhibited high abdominal accumulation, especially in pancreas and intestines, which can compromise diagnosis accuracy and cause serious adverse effects in therapy. In this context, the goal of the present work to radiolabel new BBN derivatives with {sup 11}1In and {sup 68}Ga and to evaluate their potential for BB{sub 2} positive tumors diagnosis by single photon emission tomography (SPECT) and positron emission tomography (PET). The structure of studied peptides was Q-YG{sub n}-BBN(6-14), where Q is the chelator, n is the number of glycine aminoacids in the spacer YG{sub n} and BBN(6-14) is the original bombesin sequence from the aminoacid 6 to 14. The derivative in which the last aminoacid (methionine, Met) was replaced by norleucine (Nle) was also evaluated. The experimental evaluation of the bombesin derivatives was divided into four steps: computational studies, molecular markers for SPECT, molecular markers for PET and toxicological studies. The theoretical partition (log P) and distribution (log D) coefficients were calculated for all bombesin derivatives conjugated to DTPA (diethylenetriaminepentaacetic acid) and DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) chelators applying computational programmes. Bombesin derivatives for SPECT were developed by radiolabelling DTPA-conjugated bombesin derivatives with {sup 111}In to determine the best spacer for in vivo applications, regarding the stability and in vivo properties. The derivative with the most favorable properties and conjugated to DTPA or DOTA was evaluated in comparative in vitro and in vivo studies in different BB{sub 2} expressing tumour cells, in order to determine the best chelator to be used in vivo. Some comparative studies were also performed with the BBN analogue BZH3, which was described by the literature. The molecular marker for PET was developed by radiolabelling the derivative chosen with {sup 68}Ga and evaluating the biodistribution profile in healthy and tumour mice. Finally, toxicological studies were performed by injecting an excess of cold bombesin derivatives in rats to determine their safety for clinical queries. All derivatives conjugated to DTPA were radiolabelled with {sup 111}In at high radiochemical purity and high specific activity (174 GBq/{mu}mol). The molecular markers presented high stability during radiolabelling and low stability at room temperature and this stability was increased after the addition of stabilizer agents. Stability in human serum analysis suggested time-course degradation by human serum enzymes and the increase on glycine aminoacids in the spacer improved the molecular markers stability, as long as the replacement of terminal Met by Nle. HPLC and log P results confirmed the theoretical log P data which showed that the BBN derivatives present low lipophilicity, which decreases with the increase on glycine aminoacids in the spacer and the replacement of terminal Met by Nle. In vivo studies demonstrated that {sup 111}In-DTPA-BBN analogues present fast blood clearance, excretion by renal pathway and low abdominal accumulation. Highest tumour uptake was observed with the Nle-terminal derivative (YG{sub 5}N), which was used for the comparison between the DTPA and DOTA chelators. DOTA-YG{sub 5}N was also radiolabeled with {sup 111}In at high specific activity (100 GBq/{mu}mol), but this was lower than for the DTPA derivatives. Saturation binding assays on prostate (PC-3 e LNCaP) and breast (T-47D) tumour cells showed similar affinity for the radiopeptide conjugated to DTPA and DOTA, higher binding of DOTA-peptide to PC-3 and LNCap cells was observed, but not for T-47D cells. This molecular marker was also more internalized by PC-3 cells. In vivo studies showed higher stability for {sup 111}In-DOTA-YG{sub 5}N in mice serum, and the uptake of DTPA and DOTA peptide was similar by PC-3 and LNCaP tumour, although this last tumour has shown 2-fold less BB2 receptors than PC-3. SPECT/CT imaging of PC-3 and LNCaP was possible with both radiopeptides. When compared to {sup 111}In-BZH3, the molecular markers present similar tumour uptake, but with more favorable images, because of their lower abdominal uptake. DOTA-YG{sub 5}N was radiolabeled with {sup 68}Ga with high radiochemical purity and the biodistribution profile was similar to the peptide labeled with {sup 111}In, with significative PC-3 tumour uptake. Toxicological studies showed the bombesin derivatives are safe up to concentration administered and did not present hematological, hepatic or renal toxicity. The BBN derivative YG{sub 5}N conjugated to DTPA or DOTA is a promising and safe tool for BB{sub 2} expressing tumour diagnosis by SPECT and PET. (author)

    The use of computed tomography (CT) revolutionized image diagnostic in veterinary medicine and currently can be considered one of the most useful tools for the imaging evaluation of intracranial tumor in dogs. Computed tomography of the brain in small animals allows visualization of intracranial tumor, compression of adjacent structures such as cerebral parenchyma, falx or lateral ventricles, and evaluate secondary hemorrhages and edema. The CT imaging provides essential information to indicate the surgical approach for a possible tumor resection or biopsy, including the correct location and boundaries structures involved, and also can be used to monitor the clinical treatment. However, only histopathological examination is able to confirm the final diagnosis. (author)

    To assess the efficacy and utility of computed tomography (CT) in the diagnosis of appendicitis, and to evaluate the reliability of CT findings in right iliac fossa in the confirmation or exclusion of this diagnosis. Over a one-year period, 152 patients presenting clinical signs of appendicitis underwent CT scans. The images were reviewed by two radiologists who considered whether the appendix was normal or enlarged and the existence of other signs of appendicitis for the purpose of determining whether or not the patient presented appendicitis. The definitive diagnoses were established by surgery or by clinical follow-up. The sensitivity of CT for the diagnosis of appendicitis was 81.8%, the specificity was 95.3%, the positive predictive value was 93.1%, the negative predictive value was 87.2% and the reliability was 89.9%. The signs of appendicitis observed were: appendicoliths (sensitivity 30.3% and specificity 98.8%), fluid collections (sensitivity 19.7%, specificity 96.5%), cecal enlargement (sensitivity 21.2%, specificity 97.7%), inflammation of pericecal fat (sensitivity 72.7%, specificity 90.7%), fascial thickening (sensitivity 48.5%, specificity 91.9%) and an appendix measuring more than 6 mm (sensitivity 78.8%, specificity 94.3%). Adenopathy and free peritoneal fluid were not significantly related to appendicitis. The presence of a normal appendix filled with air or contrast material had an elevated negative predictive value with respect to appendicitis. In 35 of the 94 cases with negative CT scans, the images suggested alternative diagnoses. CT is a highly reliable diagnostic method for appendicitis. The observation of an appendix filled with air or contrast material has an elevated negative predictive value. The presence of appendicoliths has an elevated positive predictive value.

    The compare the efficacy of ultrasonography and computed tomography (CT) in cases of suspected appendicitis. To study to what extent age, sex and habits of the patients, as well as the clinical context, influence the diagnostic yield of these two technique. Over a one-year period, 152 patients underwent ultrasonography and CT because of the clinical suspicion of appendicitis. The studies were carried out independently, and the results of each in terms of the presence or absence of appendicitis were unknown to the specialists performing the other. The final diagnoses were established by surgical treatment or clinical follow-up. The sensitivity of CT for the diagnosis of appendicitis was 82%, the specificity was 95%, the positive predictive value was 93%, the negative predictive value was 87% and the reliability was 90%. Ultrasonography has a sensitivity of 83%, a specificity of 97%, a positive predictive value of 95%, a negative predictive value of 88% and a reliability of 91%. Ultrasound was more efficient in patients in which there was a high clinical suspicion and in children, while the results with CT were better in patients in which the clinical diagnosis was less clear. The incidence of false negatives and positives was higher with ultrasound, while CT was more frequently able to identify a normal appendix. Sex and habits had no influence on the respective efficacies, although the performance of ultrasound was simplified in thin patients and that of CT in obese individuals. Ultrasonography and CT are highly reliable in cases of suspected appendicitis, especially when this diagnosis is conformed. Ultrasound is recommended as the technique of choice in children and in patients in which the clinical suspicion is strong. The yield of CT is somewhat greater when the clinical signs and symptoms are less clear. However, the efficacy of both techniques ultimately depends on the expertise of the specialist who interprets them. (Author) 62 refs.

    A diagnostic expert system was developed, in the Process Control Division at the Centro Atomico Bariloche, for the Embalse nuclear power plant simulator. The diagnostic system task is to interpret and show the probable cause of an abnormal transitory behaviour in the simulated process. The system was developed using artificial intelligence techniques such as: knowledge representation using rules, heuristic programming, inference under uncertainty and fuzzy sets. The diagnostic technique used consists of finding the possible cause of failure using the fault hypothesis confirmation. The faults hypothesis are organized in hierarchical form into a tree structure. The Best First search strategy is used to direct the search to those hypothesis which are confirmed with a higher degree of certainty. The diagnostic is finished when a specific hypothesis is confirmed with a high certainty factor. The diagnostic result obtained by different process fault simulation is shown. An alternative diagnostic technique is presented where the knowlegde of process structure and behaviour are represented in the form of mathematical constraints. This diagnostic method detects a suspicious component through constraints satisfaction and localizes it through constraints suspension. The validity of the method is shown by an easy example.

    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)

    Management Assets has been a theme treated with growing priority and importance by Processes Industry. Control loops are important assets to guarantee the security and operational stability of processes when they present a good performance. Usually there are a large number of control loops in processes units and their initial investment and maintenance costs are expensive. Human evaluation of control loops, in a non-systematic way, does not identify all the problems that can degrade regulatory control performance, and this the main reason to use systematic monitoring and evaluation techniques and software tools necessary to keep loops efficient. This work describes the continuous activity of monitoring and evaluation of the control systems of a petroleum refinery. Depending on some performance indexes, the loops are prioritized and some actions are taken (valve maintenance or tuning adjustment) to improve control loop performance and to avoid the reduction of product quality, raw material and utilities waste and even unit shutdown.

    The non-traumatic spinal epidural hematoma (NTSEH) is a rare entity that can be the cause of an acute spinal compression syndrome. the objective of this review is to identify the characteristics by MRI and NTSEH and to analyze the factors that influence in its prognosis. In the years 1994 and 1999, 12 patients with NTSEH have been diagnosed in our hospital, and a MRI was performed during the acute phase. the characteristics of the lesions have been analyzed by MRI, with special emphasis on the topographic data and resonance signal and the factors that can influence in the clinical prognosis of the patients. Initially, all of the patients presented pain in the cervical dorsal or interscapular site, followed by a sensitive-motor deficit picture. The MRI showed a lesion of expansive character and posterior epidural location in every case that would produce varying degrees of compression on the spinal cord. The NTSEH should be considered as one of the causes of acute spinal cord compression. The clinical association of intense cervical, dorsal or interscapular pain followed by a sensomotor deficit picture should lead to the suspicion of this entity, that would require an immediate examination with MRI to verify its diagnosis. Both the clinical manifestations as well as the characteristics observed by MRI of the NTSEH have a prognostic value and determine the therapeutic decision. (Author) 34 refs.

    Mesial temporal sclerosis (MTS) consists of hippocampal atrophy and gliosis and is the most common cause of temporal lobe epilepsy. The objective of the authors was to establish a magnetic resonance imaging (MRI) protocol for its diagnosis. A prospective study was carried out in 72 patients with drug resistant complex partial seizures (42 women and 30 men ranging in age from 6 to 66 year: mean: 30 years). Using a 1.5-Tesla magnet, paracoronal sections were made in hippocampi for T1-weighted inversion-recovery images and volume measurements, fluid-attenuated inversion-recovery (FLAIR) and T2 relaxometry. A control group of 30 health volunteers was included in the study. MTS was considered to be indicated by the presence of atrophy and hyperintensity in hippocampi on T2-weighted images. There were no differences among the hippocampi of the healthy individuals. The confidence intervals (mean{+-} 1.96 SD) were 4169 mm''3-5911 mm''3 for volume of right side, 4097 mm''3-5940 mm''3 for volume of left side and 98-113 ms for T2 relaxation time. MTS was detected in 40 patients (55.5%): 23 cases involving the left side, 13 involving the right and 4 cases of bilateral asymmetric involvement. The 95% confidence intervals for the diagnostic validity of the results (sensitivity/specificity) were (88.8%-97.2%)/(87.6%-96.4%) for T1 volumetry, (88.8%-97.2%)(95.7%-100.3%) for FLAIR and (85.4%-96.6%)/(85.4%-96.6%) for T2 relaxometry. In 5 cases of MTS, astrophy of other extra hippocampal structures was also observed, and MTS was associated with an extra hippocampal lesion (dual pathology), especially neurona migration disorders, in 8 patients. Seventeen patients (23.5%) presented lesions without MTS (tumors, cortical dysplasias and heterotopias) and there was no MRI evidence of anomalies in 15 (21%). Twenty-five patients underwent surgical treatment: 20 with MTS (19 diagnosed according to MRI and one in whom there had been no abnormal findings), 4 with tumors and 1 with a ballooned cell cortical dysplasia.

    A Centro de Produccion de Radio Farmacos de Aplicaciones en Sistemas PET will be implemented in Costa Rica. Universidad de Costa Rica will have technology that allows you to help with early detection of tumors in a much more rapid and painless. The development of PET technology in the Caja Costarricense de Seguro Social and private health sector, has been delayed by the lack of definition in the supply of radiopharmaceuticals; due to the high cost of a cyclotron system and ensuring its profitability, being here where the Universidad de Costa Rica come to play a key role as an impartial figure in the scheme of national implementation. Therefore, a bilateral agreement is exposed for the daily supply of radiopharmaceuticals in place at a cost inversely proportional to the volume of consumption and enabling financial sustainability of the project. This agreement must be established between the Universidad de Costa Rica and the Caja Costarricense de Seguro Social, and then seek expansion of marketing with the private sector nationwide. A SWOT (Strengths, Weaknesses, Opportunities and Threats) is developed on the project. Also, the geographical location of the project facilities is showed, the architecture of the project cost without operations. Finally, the architectural design of the building is presented [es

    The identification and surgical removal of foreign bodies is a complex procedure in medical practice, principally when the involved material is radiolucent. The technological advent of the ultrasonography equipment comes enlarging the field of application of this method more and more, in medical practice. The authors describe a case of an ultrasound guided surgical removal of glass fragments from the face of a patient. The foreign bodies were previously diagnosed by ultrasound and computed tomography. The guided technic showed secure, less invasive and efficient, allowing the retreat of all the fragments. (author)

    Objective: to evaluate the diagnostic capacity of abdominal computed tomography in the assessment of hepatic steatosis using the portal phase with a simplified calculation method as compared with the non-contrast-enhanced phase. Materials and methods: in the present study, 150 patients were retrospectively evaluated by means of non-contrast-enhanced and contrast-enhanced computed tomography. One hundred patients had hepatic steatosis and 50 were control subjects. For the diagnosis of hepatic steatosis in the portal phase, the authors considered a result of < 104 HU calculated by the formula [L - 0.3 Multiplication-Sign (0.75 Multiplication-Sign P + 0.25 Multiplication-Sign A)] / 0.7, where L, P and A represent the attenuation of the liver, of the main portal vein and abdominal aorta, respectively. Sensitivity, specificity, positive and negative predictive values were calculated, using non-contrast-enhanced computed tomography as the reference standard. Results: the simplified calculation method with portal phase for the diagnosis of hepatic steatosis showed 100% sensitivity, 36% specificity, negative predictive value of 100% and positive predictive value of 75.8%. The rate of false positive results was 64%. False negative results were not observed. Conclusion: The portal phase presents an excellent sensitivity in the diagnosis of hepatic steatosis, as compared with the non-contrast-enhanced phase of abdominal computed tomography. However, the method has low specificity. (author)

    Combined CT Venography and Pulmonary Angiography was described in 1998 as a tool for diagnostic Thromboembolic Disease. The purpose is to relate our own experience with this technique in a population with suspected pulmonary embolism. 46 consecutive patients with suspected pulmonary embolism underwent combined CT Venography after Pulmonary CT Angiography to depict Deep Venous Thrombosis (DVT). CT Venography where obtained with a 3 minutes delay from injection, without additional intravenous contrast, from upper abdomen to fibular head. A prospective study from emergency reports where used. The reports where aimed by nine different radiologist at diary emergency room (images where not retrospective review). We report if a pulmonary embolus or deep venous thrombus or another alternative diagnostic where done. An endo luminal thrombus in any pulmonary arteries was assessed as a positive study for PE. A Thrombus in the leg veins or in an abdominal vein without diminished size of vein was assessed as an acute DVT. In those patients with a CT negative to Thromboembolic Disease was the clinician who decide if more proves where needed. Those patients without evidence in CT of Thromboembolic Disease where asked for symptoms related to the episode in a 3 months period after initial CT. Patients free of symptoms for 3 months without anticoagulation therapy where considered true negative for CT. CT shows Thromboembolic Disease in 23 of 46 patients. 21PE, 14 DVT 2 of 14 patients with DVT don't show PE, CT excluded thromboembolic disease in 23 patients and in 15 of those patients an alternative diagnostic was shown. In 22 of those 23 patients CT excluded correctly Thromboembolic Disease. One patient result in a false negative CT, Pulmonary Angiography of that patient shows us a subsegmentary embolus.

    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)

    In slaughterhouses, operations developed since the 'ante-mortem' until to the storage of the product, are heavily dependent on electric energy and responsible for the final product quality. The study of the size related to the consumption of electrical energy and the associated cost of this energy in the stages of the slaughter, are important not only for the entrepreneur but also for the final consumer. This way, aiming at to accomplish a preliminary diagnosis in relation to the use of the electric power, was measured values of the main electric parameters of the transformers slaughterhouse to know preliminary the use of this energy inside of the establishment. Later, in the continuation of this work, detailed and complemented studies will be accomplished in the several processes aiming at to diagnose, to analyze and to propose solutions to lead to the rational use of the electric power, without interfering, or to maintain, the quality of the final product in the lines of production of the poultry slaughterhouse, including the storage process that uses of chambers of cooling and freezing.

    The fault detection and diagnosis system is an Operator Support System dedicated to specific functions that alerts operators to sensors and actuators fault problems, and guide them in the diagnosis before the normal alarm limits are reached. Operator Support Systems appears to reduce panels complexity caused by the increase of the available information in nuclear power plants control room. In this work a Monitoring and Diagnosis System was developed based on the GMDH (Group Method of Data Handling) methodology. The methodology was applied to the IPEN research reactor IEA-R1. The system performs the monitoring, comparing GMDH model calculated values with measured values. The methodology developed was firstly applied in theoretical models: a heat exchanger model and an IPEN reactor theoretical model. The results obtained with theoretical models gave a base to methodology application to the actual reactor operation data. Three GMDH models were developed for actual operation data monitoring: the first one using just the thermal process variables, the second one was developed considering also some nuclear variables, and the third GMDH model considered all the reactor variables. The three models presented excellent results, showing the methodology utilization viability in monitoring the operation data. The comparison between the three developed models results also shows the methodology capacity to choose by itself the best set of input variables for the model optimization. For the system diagnosis implementation, faults were simulated in the actual temperature variable values by adding a step change. The fault values correspond to a typical temperature descalibration and the result of monitoring faulty data was then used to build a simple diagnosis system based on fuzzy logic. (author)

    In Patagonia there are academic centers, health and industrial facilities that use ionizing radiations in its usual practices. However, they do not have protocols that respond to local needs. For this reason was held from October 5 to November 10, 2012 in Bariloche Atomic Center, a training course for health personnel. The range of topics covered ranged from the definition of dosimetry quantities, types of radiation and biological dosimetry, biological effects, radiation acute syndrome, radiation-induced cutaneous syndrome, internal contamination, screening in radiological emergencies, etc.The course provided a theoretical and practical guide about how to recognize and treat people exposed to radiations, guidelines for acting in radiological emergencies and a perception of the psychosocial impact of the radiation accidents.The result was a pocket book for health personnel that will be used in case of having a patient with radiation induced injury.

    Datos Estadísticos
    Debemos referirnos casi exclusivamente a los datos aportados por los textos y revistas norteamericanos y europeos puesto que nuestro país carece en forma prácticamente total de estadísticas confiables en este campo.

    En 1900 habían sido publicados menos de 80 casos en la literatura médica mundial. En 1912, el Dr. Isaac Adler en su Tratado Clásico sobre “Tumores Primarios de Pulmón y Bronquios” informó 400 casos. La incidencia aumentó progresivamente. El uso del cigarrillo y la polución ambiental han contribuido a este aumento inicialmente en el hombre y en las últimas décadas en la mujer, hasta el punto que en 1930 hubiesen muerto 2.357 personas por esta causa en Estados Unidos; en 1943, 9.205 Y en 1950, 18.313. Durante los siguientes 25 años la mortalidad por esta causa se disparó pasando de 24 a 67.5 por 100.000 en los hombres (un 185% de aumento y de 5 a 16.6 por 100.000 en mujeres (un 239% de aumento.

    Es de anotar que ningún otro tipo de cáncer aumentó más de 3 por 100.000 en el mismo lapso. Prácticamente se podría hablar de una epidemia de cáncer pulmonar. Durante este período de 25 años, la proporción de los que fueron detectados y curados fue del 20 al 25% con una sobrevida a 5 años del 8 al 10%.

    En 1981 se detectaron 122.000 nuevos casos en EE.UU. y 105 mil muertes por carcinoma broncogénico. En el curso de la presente década la mujer alcanzará al hombre en este campo. El cáncer del pulmón causael25% de todas las muertes por cáncer y el 5%de todas las muertes. La mortalidad por cáncer del pulmón alcanzó ya en 1985 a la producida por accidentes de tránsito. Todos estos datos corresponden a estadísticas estadounidenses.

    Las técnicas y enfoques modernos de tratamiento han permitido descubrir la lesión en etapas más tempranas, y por tanto tratarla en un período mejor para lograr mayor sobrevida. A esos métodos nos vamos a referir.

    Como mencionamos, las estadísticas colombianas a nuestro alcance no son muy completas, pero indican así mismo una tendencia ascendente realmente impresionante tanto en hombres como en mujeres.

    En la actualidad la cirugía de resección es el tratamiento de elección en la mayoría de los casos. Para llegar a una cirugía que tenga posibilidades de curación o de sobrevida útil importante, es necesario cubrir una serie de parámetros tanto en la clasificación como en la selección y agrupación de los casos que han de ser sometidos a técnicas quirúrgicas; así mismo éstas no deberán ser como en anteriores épocas, cirugías prácticamente de demostración de habilidad por parte del cirujano, de gravísimo riesgo para el paciente, sino técnicas que, muy bien indicadas y ejecutadas, puedan (en aquellos casos que por su clasificación así lo ameriten llevar al éxito quirúrgico y a sobrevida útil a 5 años en alto porcentaje de los casos...

    Multislice computed tomography has advantages in comparison to conventional computer tomography such as reduction in study time, lower radiation dose, fewer metal artifacts and high quality multiplanar reformatting and three-dimensional reconstructions. We reviewed approximately 300 lumbar spine examinations and selected the most illustrative cases including congenital anomalies, degenerative lesions, spinal infections, neoplasms traumatic injuries, spondylolysis and postoperative changes. In the majority of the cases the high quality multiplanar reformatted and volume reconstructions of multislice computed tomography allowed better evaluation of the lesions, particularly in the cases of complex anatomy (author)

    Ionizing radiation metrology is the base to achieve reliable dose measurements in ali areas; it is also part of the framework that is established to assure radiation protection procedures in order to avoid or minimize the harmful biological effect that may be caused by ionizing radiation. A well done metrology means the use of reliable instruments that comply with standard performance requirements worldwide accepted. Those instruments are expected to be calibrated by Metrology Laboratories under well defined conditions. The International Electrotechnical Commission (IEC) in Standard 61267 established the reference radiations for medical diagnostic x-ray equipment that are recommended to be used for calibrating dosimetric systems for diagnostic dosimetry. In this work, X-ray beam qualities were established in a Calibration Laboratory and their characteristics were analyzed through the measurement of beam parameters like inherent tube filtration, beam uniformity and field size, energy spectra and peak voltage for additional filtration with 94.425 por cent and 99.999 por cent purity filters. Also, the first half-value layer and the homogeneity coefficient were measured for the three RQR 2, RQR 6 and RQR 10 IEC beam qualities and they were analyzed according to the IEC standard. Air-kerma measurements were carried out with an ionization chamber that had its reliability confirmed through repetition and reproducibility reading tests. In 50 sets of measurements the maximum standard deviation found of 10 successive readings was 0.19 %; the maximum shift of the reading mean value at a fixed geometry condition was 0.80 % with an overall standard deviation of 0.23 %. Results showed that the use of different purity filters did not cause a relevant influence on the beam energy spectra. An ionization chamber was also calibrated against a standard dosimeter in ali implemented reference radiations and the relevant sources of uncertainties were estimated. Calibration could be done with an expanded uncertainty of 1.50% for a coverage factor of 2 at a 95.45 % confidence level, mainly due to the uncertainty of 0.58% caused by the positioning set-up of the ionization chamber.

    To assess the value of ultrasound as an initial diagnostic method in cases of acute diverticulitis. Ultrasound was carried out in 76 patients with a clinical diagnosis of acute sigmoid diverticulitis. The final diagnosis was based on the clinical course in every case, as well as on computed tomography (CT; n=46), histopathological examination (n=10), colonoscopy (n=4) and barium enema (n=2). The diagnostic criteria established for ultrasound was a thickening of the sigmoid colon wall of >4 mm and the presence of a least one of the following features: diverticular, phlegmon or abscess. The CT diagnosis was based on two indispensable findings: thickening of the sigmoid colon of>4 mm and inflammation of pericolonic fat. The final diagnosis was acute diverticulitis in 52 patients, some other disease in 18 and undetermined in 6. The sensitivities of ultrasound and CT were 81% and 94%, respectively, and their specificities were 79% and 83%, respectively. Of the 10 false negatives on ultrasound, seven corresponded to cases of simple diverticulitis and three to cases of complicated diverticulitis (two in patients with abscess and one in a patient with pneumoperitoneum). CT provided the correct diagnosis in eight of these cases, and resulted in false negatives in two cases of mild diverticulitis. Ultrasound is a valid test in the initial diagnosis of acute diverticulitis of the sigmoid colon.

    Full Text Available Introducción: El proceso de medicalización de la sociedad ha generado una dependencia de la biomedicina para entender, gestionar y legitimar la enfermedad. Como consecuencia surge una nueva forma de considerar los procesos corporales que transforma las identidades y subjetividades de los individuos y los grupos sociales. La enfermedad se concibe y se experimenta en el cuerpo en forma de signos y síntomas. Esta representación de la enfermedad compartida por expertos y enfermos durante el encuentro clínico se convierte en el lenguaje propio de la interacción. Esto ocurre incluso en casos, como el de la fibromialgia, en los que el diagnóstico se produce en ausencia de alteraciones ‘objetivas’ del cuerpo. Metodología: Observación participante, sobre la elaboración y comunicación del diagnóstico de fibromialgia en una consulta de reumatología. Resultados: Se analizan las representaciones sobre el cuerpo y la enfermedad que manejan tanto médicos como enfermos, y la utilización de los síntomas corporales como estrategia de legitimación e interacción durante el encuentro clínico. Conclusión: En la fibromialgia, a pesar de la ausencia de alteraciones biológicas ‘objetivas’, la relación sanitario-paciente se ve mediada por el cuerpo. Este es el lugar en el que se producen las intervenciones terapéuticas y el vehículo de la comunicación entre ambos.Introduction: The process of medicalization of the society has generated a dependence of the biomedicine to understand, to negotiate and to legitimate the illness. As consequence arises, a new form of considering the bodily processes that transforms the identities and the individuals' subjectivities. Persons conceive and experience the illness in the body as signs and symptoms. This representation of the illness shared by experts and patients during the clinical encounter it becomes the characteristic language of the interaction. This even happens in cases, as that of the fibromyalgia, in those that the diagnosis takes place in absence of 'objective' alterations of the body. Methods: Fieldwork carried out over a six-month period in two different outpatient rheumatology clinics. I used participant-observation to explore doctor-patient interaction and the diagnostic process of fibromyalgia. Results: I analyzed the representations about the body and the illness used by medical as patients, and the use of the corporal symptoms as legitimation strategy and interaction during the clinical encounter. Conclusion: In fibromyalgia, in spite of the absence of biological ‘objective’ alterations, the body mediates the doctor-patient relationship. This is the place of the therapeutic interventions and the vehicle of the communication between both.

    Multidetector-row computed tomography (MRCT) has advantages in comparison to conventional helical computed tomography, such as reduction of study time, lower radiation doses, fewer metallic artifacts and high quality multiplanar reformatting and three dimensional reconstructions. We reviewed 150 cervical spine examinations and selected the most illustrative cases including congenital anomalies, degenerative lesions, spinal infections, neoplasms, traumatic injuries and postoperative abnormalities. The quality of multiplanar reformatting and volume reconstructions of the MRCT made the detection and evaluation of most of cases with complex anatomy easier and more precise. (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)

    Purpose: to establish the main signs of placental accretism in magnetic resonance imaging (MRI) in patients with clinical suspicion and to estimate the benefit of this method. Methods: prospective transversal study with 15 patients suspected of placental accretism, referred between March 2003 and February 2006. Gestational age varied from 20 to 31 weeks. All patients underwent MRI to study the placenta and had previously done an ultrasonography. Material was sent to histological study. MRI was done on Magnetom Impact and Sonata Maestro Class Siemens{sup R}, with acquired sequences HASTE, TURBO SPIN in axial, sagittal, coronal planes and echo gradient (GE{sup R}), pre- and post-dynamic contrast in the best plan for acquisition. Images were analyzed by a team of two radiologists. Results: mean gestational age was 24.3 weeks. We studied seven placenta previa (47%), six anterior placentas (40%) and two posterior placentas (13%). Ultrasonography was positive in 80% of the placentas and MRI in 53%. However, echography had a low concordance with anatomic pathological studies by Kappa test (11%), revealing 75% of sensitivity, 14% of specificity, 50% as positive predictive value (PPV) and 33% as negative predictive value (NPV). MRI had an excellent concordance with anatomic pathological studies (0.86), showing 100% of sensitivity, 86% of specificity, 89% as PPV and 100% as NPV. Conclusions: MRI is useful for placental accretism diagnosis. The principal findings are transmural hyper-signal, the loss of continuity in myometrial wall in fast sequences and the identification of vessels invading myometrial layer in dynamic sequences.

    Full Text Available ABSTRACT:Introduction: Legionella species are Gram-negative bacilli. There are described for the first time in 70's associated to the Legionnarie's disease. Presently, more than 34 species of Legionella have been identified, 20 of which have been found pathogenic for the man. The clinical manifestations of Legionella infections are primarily respiratory. The most common presentation is acute pneumonia, which varies in severity from mild illness that does not require hospitalization to fatal pneumonia.Material and Methods: The results corresponding to the determination of antibodies to L. pneumophila (Gull Laboratories by indirect inmunofluorescence (IFI have been analysed and reviewed. This conventional inmunofluorescent test measures antibodies versus a pool of 1, 2, 3, 4, 5, 6, 7 and 8 serogroups. During the 3 years of surveillance period 1249 determinations by IFI were performed in our Hospital. The determination of urinary antigen of Legionella for the qualitative detection of the antigen to L. pneumophila serogroup 1 was made in almost all studied samples by using a fast inmunochromatographical technique (Binax NOW.Results and Discussion: Of the 1249 cases of nosocomial pneumonia (diagnosed by a positive result of IFI Legionella test recorded during the period, 12 cases met the criteria for infection with L. pneumophila serogroup 1. Later, clinical histories were reviewed and it was observed that the ages of the confirmed cases oscillated between the 40 and 87 years, with an average of age of 40, of which 8 were men and 4 women. From the point of view of factors of risk, 6 patients were smokers. Clinically, the displayed symptoms were general malaise, fever high and pattern of pulmonary infiltration in all the cases, migraine in 3 cases, diarrhoea in 5 cases and arthralgias and muscle aches in 3 cases. The analytical parameters in common were high VSG and leukocytosis. Hyponatremia 1/1024, what it demonstrates a clear seroconversion. In other two cases the title of the first sample already was > 1/1024.Although in our casuistic the incidence of pneumonia by Legionella is low, we can observe the importance of the determination of the urinary Legionella antigen as well as the delayed appearance of antibodies. The clinical importance of this single observation carried us to practice a second determination of antibodies when the suspicion of pneumonia by Legionella is high. RESUMEN.Introducción: Las especies de Legionella son bacilos gram negativos. Fueron descritas por primera vez en los 70 asociados a la enfermedad de los legionarios (EL. Casi la mitad de las 34 especies conocidas son patógenas para el hombre. Las manifestaciones clínicas de infecciones por Legionella son fundamentalmente respiratorias. La forma más común es la neumonía aguda, que varía en severidad de enfermedad suave que no requiere hospitalización a neumonía fatal.Material y Métodos: Se han estudiado y revisado los resultados correspondientes a la medición de anticuerpos frente a L. pneumophila por inmunofluorescencia indirecta, IFI (Gull Laboratories, que determina anticuerpos frente a un pool de serogrupos 1, 2, 3, 4, 5, 6, 7 y 8. El número de resultados obtenidos por IFI, correspondientes al periodo 2000-2003, ha sido de 1249, procedentes de diferentes Servicios de nuestro Centro.La determinación de antígeno urinario de Legionella, se ha realizado, en casi todas muestras estudiadas, mediante una técnica inmunocromatográfica rápida para la detección cualitativa del antígeno serogrupo 1 de L. pneumophila (Binax NOW.Resultados y Discusión: De todas las determinaciones realizadas (1249, solo se han confirmado 12 casos de neumonía por Legionella. Posteriormente, se revisaron las historias clínicas y se observó que las edades de los casos confirmados oscilaban entre los 40 y 87 años, con un promedio de edad de 40, de los cuales 8 eran varones y 4 mujeres. Desde el punto de vista de factores de riesgo 6 eran fumadores.Clínicamente los síntomas presentados fueron: malestar general, fiebre alta y patrón de infiltración pulmonar en todos los casos, cefalea en 3 casos, diarrea en 5 casos y artralgias y mialgias en 3 casos. Como parámetros analíticos comunes a todos los casos se observaron VSG elevada y leucocitosis. La hiponatremia inferior a 130 sólo se observó en 1 caso.La determinación de antígeno de Legionella fue positiva en 9 casos. En los 3 casos en que resultó negativa ha de interpretarse que la enfermedad fue producida por un serogrupo diferente del 1 (que es el que se detecta en la muestras de orina.La determinación de anticuerpos frente a L. pneumophila por IFI se realizaron todas en el momento del ingreso. En 7 casos el título fue 1/1024, lo que nos demuestra una clara seroconversión. En otros dos casos el título de la primera muestra ya fue > 1/1024.Aunque en nuestra casuística la incidencia de neumonía por Legionella es baja, es posible observar la importancia de la determinación del antígeno urinario de Legionella así como la aparición tardía de anticuerpos. Estos hallazgos nos refuerzan el interés de practicar una segunda determinación de anticuerpos cuando la sospecha de neumonía por Legionella es alta.

    A comparison among the design techniques of shielding for X-ray diagnostic rooms with the NCRP 49 (1976) report technique, AAPM 39 (1993) Y the one of the NCRP 147 (2005) technique. The designs correspond to a room of conventional X-rays, one of fluoroscopy, one of tomography Y one of mammography. In all the cases it demonstrates that the NCRP 49 technique overestimate the shieldings. The causes of the overestimation of the NCRP 49 can be attributed to: a) high values of the work charge that don't consider the spectral fluence of the photons that are present in each room, b) to the differences in the values of the kerma in air without attenuation for the dispersed primary radiation Y of leakage among both reports.

    Small-vessel vasculitis is a convenient descriptor for a wide range of diseases characterized by vascular inflammation of the venules, capillaries, and/or arterioles with pleomorphic clinical manifestations. The classical clinical phenotype is leucocytoclastic vasculitis with palpable purpura, but manifestations vary widely depending upon the organs involved. Histopathologic examination in leucocytoclastic vasculitis reveals angiocentric segmental inflammation, fibrinoid necrosis, and a neutrophilic infiltrate around the blood vessel walls with erythrocyte extravasation. The etiology of small-vessel vasculitis is unknown in many cases, but in others, drugs, post viral syndromes, malignancy, primary vasculitis such as microscopic polyarteritis, and connective tissue disorders are associated, The diagnosis of small- vessel vasculitis relies on a thorough history and physical examination, as well as relevant antibody testing including antinuclear antibody and anti neutrophil cytoplasmic antibody, hepatitis B and C serologies, assessment of complement, immunoglobulins, blood count, serum creatinine liver function tests, urinalysis, radiographic imaging and biopsy. The treatment is based primarily on corticosteroid and immunosuppressive agents.

    The obtention of images of human body to the medical diagnostic is one of the more old and generalized applications for X-ray. Therefore the design and performance of equipment and installations as well as the operation procedures must be oriented toward safety with the purpose to guarantee this radiological practice will bring a net positive benefit to the society. Given that in Mexico only exists the standardization related to source and equipment generators of ionizing radiation in the industrial area and medical therapy, but not so to the medical diagnostic area it is the purpose of this work to present those standards related with this application branch. Also it is presented the preparation of a manual for the course named Formation of teachers in radiological protection and safety in the X-ray medical diagnostic in 1997 which was imparted at ININ.

    Thyroid nodules are a common disorder, with 4-7% of incidence in the Brazilian population. Although the fine needle aspiration (FNA) is an accurate method for thyroid tumors diagnosis, the discrimination between benign and malignant neoplasm is currently not possible in some cases with high incidence of false negative diagnosis, leading to a surgical intervention due to the risk of carcinomas. The aim of this study was to verify if the Fourier Transform infrared spectroscopy (FTIR) can contribute to the diagnosis of thyroid carcinomas and goiters, using samples of tissue and aspirates. Samples of FNA, homogenates and tissues of thyroid nodules with histopathological diagnosis were obtained and prepared for FTIR spectroscopy analysis. The FNA and homogenates samples were measured by {mu}-FTIR (between 950 . 1750 cm{sup -1}), at a nominal resolution of 4 cm{sup -1} and 120 scans). Tissue samples were analyzed directly by ATR-FTIR technique, at a resolution 2 cm{sup -1}, with 60 scans in the same region. All spectra were corrected by the baseline and normalized by amides area (1550-1640 cm{sup -1}) in order to minimize variations of sample homogeneity. Then, spectra were converted into second derivatives using the Savitzk-Golay algorithm with a 13 points window. The Ward's minimum variance algorithm and Euclidean distances among the points were used for cluster analysis. Some FNA samples showed complex spectral pattern. All samples showed some cell pellets and large amount of hormone, represented by the bands of 1545 and 1655 cm{sup -1}. Bands in 1409, 1412, 1414, 1578 and 1579 cm{sup -1} were also found, indicating possible presence of sugar, DNA, citric acid or metabolic products. In this study, it was obtained an excellent separation between goiter and malign lesion for the samples of tissues, with 100% of specificity in specific cluster and 67% sensibility and 50 of specificity. In homogenate and FNA samples this sensibility and specificity were lower, because among these samples, it were included many types of thyroid lesions. To obtain a more precise diagnosis for FNA of follicular thyroid the sample size should be increased. The results of this study suggest that FTIR spectroscopy may be useful for discriminate thyroid carcinomas from goiters in tissue samples. (author)

    Tuberculosis (TB) is one of the oldest infectious diseases in the world and still affects humanity today. Since 1993, the World Health Organization (WHO) considers TB as a global emergency. The clinical history of the individual, the serum exams and particularly, the imaging examination of the thorax, are used for diagnostic confirmation and monitoring of disease. TB is a chronic disease that usually evolves with pulmonary sequelae that must be monitored. The exam of the image more precise to assess the radiological patterns found in these patients is high-resolution computed tomography (HRCT), which aids in medical diagnosis and permit the determination of the area affected by radiological abnormalities of pulmonary tuberculosis. The best known of such modifications by means of exams or more accurate techniques is of extreme importance. Therefore, this study aimed to show the quantification, performed by algorithms, of the areas affected by the radiological abnormalities of TB through the HRCT, and compared with serum exams. We studied 16 patients with confirmed diagnosis of TB. The serum exams evaluated included: hemoglobin, hematocrit, albumin, speed hemo sedimentation and C-reactive protein. With the values of serum exams we observed that patients have anemia, low albumin levels and inflammatory activity, corroborating imaging exams, which show severe impairment of lung area due to the inflammation caused by disease activity.

    The gastroesophageal reflux disease is characterized by the return of gastric liquid to the esophagus which can origin the reflux esophagitis. The aim is to evaluate the contribution of dynamic quality scintigraphy of reflux (CTR) in the diagnosis of DRGE. We studied a ground of sick people with typical symptoms and compared the results given by digestive endoscopy (EDA), the histopathology and 24 hours pHmetry. There have been evaluated 24 healthy individuals and 97 who were sick. The first ones were submitted to CTR. In 20 controlled and 34 patients, the reflux index (IR) was determined by the evaluation of the reflux material percentage in relation to the basal activity. All the sick patients were submitted to CTR and EDA. This one classified them in: group A with esophagitis 45 patients (46,4%) where 14 did the biopsy of the third segment/part from the esophagus and 16 did the long pHmetry and group B without esophagitis = 52 patients (53.6%), 26 did the biopsy and 36 the pHmetry. In group A the CTR was positive in 38 (84%), the biopsy showed esophagitis in 11 (78,6%) and the pHmetry showed normal reflux in 14 (87,5%). The positivity of the same exams in group B were of 42 (81%), 11 (42,3%) and 19 (53%) respectively. The IR were determined to the controls and the measure to the patients were of 59% and 106% respectively as p<0,0001 (test from Mann Whitney). The correlation of CTR with the other methods showed sensitivity of 84,1%, specificity of 95,8%, positive predictive value of 98,3% and negative predictive value of 67,7%. As it was showed the authors concluded that the scintigraphy method can confirm the diagnosis of DRGE in patients of typical symptomology which canbe recommended by the initial of investigation method in these conditions.

    Full Text Available Un defecto ventilatorio restrictivo está caracterizado por una reducción en la capacidad pulmonar total. El objetivo de este estudio fue evaluar la utilidad de la espirometría para determinar la presencia de restricción en pacientes con y sin obstrucción bronquial. Fueron incluídos 520 pacientes. Se definieron los valores normales mediante el intervalo de confianza del 95% (IC utilizando la ecuación de Morris para la espirometría, y la de la European Respiratory Society (ERS para capacidad pulmonar. Las espirometrías fueron clasificadas como obstructivas cuando mostraban relación volumen espiratorio forzado en 1 segundo (VEF1/capacidad vital forzada (CVF A restrictive ventilatory defect is characterized by a decreased total lung capacity (TLC. The objective of this study was to determine the accuracy of spirometry to detect pulmonary restriction in patients with or without airflow obstruction in the spirometry. Five hundred and twenty patients were included. Normal values for lung function were determined by using the 95% confidence interval (CI with Morris reference equation for spirometry and European Respiratory Society equation for lung volume. Spirometries were considered obstructive when FEV1/FVC ratio was <70% and FEV1 was below 95%CI. In patients without obstruction in the spirometry (n = 357 sensitivity and specificity were 42.2% and 94.3% respectively, negative predictive value (NPP was 86.6% and positive PV (PPV was 65.2%. In patients with an obstructive spirometry (n = 66 sensitivity increased to 75.8% but specificity decreased to 65.9%. PPV was only 57.8% and NPV 81.5%. Patients showing obstruction in the spirometry and false positives of a low FVC (n = 22 had similar values of FVC (57.36 ± 13.45 vs. 58.82 ± 8.71%, p = 0.6451, FEV1 (44.73 ± 19.24 vs. 44.0 ± 13.08%, p = 0.8745 and DLCO (67.50 ±27.23 vs. 77.00 ±16.00%, p = 0.1299 than true positives. Residual volume (RV (125.72 ± 64. vs. 77.96 ± 29.98%, p = 0.0011 and RV/ TLC ratio (56.89 ± 12.82 vs. 38.43 ± 13.07%, p = <0.0001 were significantly higher. We conclude that a decreased FVC or VC cannot be considered evidence of ventilatory restriction in the presence of airflow obstruction on spirometry. Diagnosis of "mixed defects" by spirometry is inaccurate and should be avoided without the measurement of lung volumes.

    There is little information on developing countries about the use of diagnostic imaging procedures and the doses associated with radiological examinations. This study assessed the pattern and trend of diagnostic imaging usage in outpatients of the Brazilian Unified Health System (SUS) by modality and examined body part. Emphasis was given to computed tomography (CT) scans for which the analysis was extended to the private health care sector and included the evaluation of age at examination distribution, and dose estimation for children and young adults. Information on the use of diagnostic imaging procedures among SUS outpatients was obtained from the Outpatient Information System (SIA) of the Department of Information Technology of SUS (DATASUS). Data on the use of CT in the private health care sector were extracted from the Radiological Information Systems (RIS) of 25 private radiology services in 8 Brazilian cities. Effective doses and absorbed doses on organs of interest were estimated individually for 4,497 patients younger than 20 years of age using CT scan technical parameters and Monte Carlo simulations of radiation transport. Between 2002 and 2012 it was observed that conventional radiology was the most frequent modality of diagnostic imaging in SUS outpatients, but more sophisticated modalities, such as CT and magnetic resonance imaging, had the highest growth rates over the study period. The most frequent CT scan in SUS outpatients between 2001 and 2011 was the head/neck exam, but abdomen/pelvis examinations were the ones that grew the most. Patients up to 20 years of age made approximately 13% and 9% of the CT examinations between 2008 and 2014 in the public and private health care systems, respectively. About one-third of the private-sector patients had more than one CT scan in this period. There was great variation in doses, even for the same type of procedure in patients of the same age group. The highest mean effective dose was 13.5 mSv estimated for abdomen/pelvis CT in children younger than one year of age. The highest absorbed doses were estimated for the brain after head/neck CT (23.8 to 29.0 mGy), which was the most common type of CT in children and young adults in the study period. The intense increase, the magnitude of the estimated doses and the large proportion of pediatric CT scans in Brazil point out to the need for initiatives to promote appropriate justification and optimization of these examinations in Brazil.

    One of the most important causes of residual damage in skeleton is incompletely treated osteoarticular infections (OAI). Goal: to assess the value of emergency three-phase bone scan (3FBS) in the evaluation of OAI. Methods: Thirty-eight children were studied with 54 3FBS. Results: Global analysis: 76% of the cases were principally articular; staphylococcus germs and hip's affection were the common. Nine patients with preoperative scan were positive with 16 foci, 86% confirmed by surgery cultivate. Seven children had negative 3FBS without posterior clinical symptomatology; in 5 of them it was demonstrated soft tissue involvement with normal osteoblastic phase. In 14/17 cases evaluated after surgical intervention, there was a relation between the scan and the clinical course. In two of those cases, in the 3FBS a new location was found. Conclusion: 3FBS is a helpful tool in the diagnosis and assessment of acute OAI in pediatric population. A positive 3FBS is highly accurate for OAI and a negative one rules it out securely (au)

    Recent foraminifera assemblages were studied to determine an ecological model of species distribution, diversity, equability and confining degree, with implications to environmental diagnosis and paleoenvironmental reconstructions. The study area is inserted in a sector from Sao Francisco River delta, with interconnected channels and a lagoon connected to the ocean. Besides the biotic variables, sediment salinity and granulometry was considered. An agglomerative hierarchical clustering (AHC) was performed and it was recognized three bio facies distributed along the sector: Miliammina/Arenoparrella in the channels, and Ammonia/Elphidium and Quinqueloculina at the lagoon. The diversity and equability values increase from the Miliammina/Arenoparrella biofacies to the Ammonia/Elphidium and Quinqueloculina biofacies. The confining indices show environments ranging from confined (channels) to different degrees of low restricted to marine influence. From the results obtained, it is possible to recognize that environments dominated by textulariines are characterized by low diversity, equability and high confining degree. Environments dominated by rotaliines and miliolines tend to be more diversified, equitable and low restricted to marine influence. The results are similar to other obtained in other Brazilian estuarine environments, differing only on dominance by some species (author)

    The search for more efficient thermal cycles has led a growing complexity of these cycles and therefore increased the inter-relationships between the thermodynamic components. This complexity is further enhanced with the over time, due to the occurrence of both natural as early degradation in a more or less degree, of all plant components. Several methodologies have been proposed for creating system for diagnostic / prognostic with the objective to detect these degradations (defects) and quantify the gain that can be obtained in the performance indicators of thermal cycles (usually specific fuel consumption and power net) by the elimination of anomalies. Two points have been emphasized as the most difficult in the development of such systems: the distinction between the performance variation of the components due only to the point of operation outside of these project components, caused by the presence of abnormality in another component (induced malfunction) and a decrease in the performance due to the presence of anomalies in the component itself (intrinsic malfunction). The second difficulty is the quantification of the effects induced by the elimination of each of the present anomalies. This work makes use of the method of reconciliation and using individual models of each component to predict unusual behavior of the same design point. The comparison of data from the system plant information, relating to the current state and data from the models, is used to detect anomalies. The methodology is explained in detail and an application of it in a Rankine cycle is used to well understand, especially in parts for the elimination of induced malfunctions, and related to the induced changes by the elimination of each one of the anomalies.

    The present paper reports a social, environment and economic diagnosis in an oil and energy organization, in the enlargement of its plant. Attending to some previous requirements made by this company, the diagnosis was accomplished making use of an innovative evaluation tool called MADSA{sup R} (Social and Environmental Evaluation Matrix). Through the customization of this tool, it was possible to evaluate, systematically, the performance of the engaged companies hired by the organization to implement its enterprise, based on proposed actions in QSMS - Quality, Safety, Environment and Health. The performance evaluation was supported by the employees', the organization, its clients' and the local community perception. MADSA{sup R} methodology made it possible to measure the accomplished gain through proposed actions. The development of a performance indicator allowed the comparison between achieved results and accomplished investments. It was concluded that MADSA{sup R} provided subsidies to elaborate an action plan to improve the organization achievements, since it was able to represent the strategy of the organization, to guide and standardize actions, to identify and quantify points to be made better of.

    Stromal tumors of the gastrointestinal tract encompass a group of neoplasms representing 1% to 3% of all digestive system tumors. When located in the stomach, their tendency to exhibit and exophytic growth pattern makes it necessary to establish the differential diagnosis with respect to other gastric tumors (lymphoma, exophytic adenocarcinoma) and nongastrointestinal masses. We present a case that illustrated the difficulties associated with the imaging diagnosis of these lesions and the importance of modern radiological techniques (helical computed tomography and magnetic resonance) and the correct interpretation on the part of radiologists to orient pathologists and clinicians toward the diagnosis and proper treatment.

    In this paper the development of a computer tool for the analysis of centrifugal pumps is presented. This tool allows the user to analyze the performance of the pump by means of the analysis of the behavior curves at its design conditions, reference and operation. In order to realize the analysis it is necessary that the user feeds the tool with the missing and necessary information according to norm ASME PTC 8.2 and under the specified conditions of calibration of the same norm, to eliminate possible errors in the results, a bad qualification or erroneous acquisition of the signals. The system must early be fed with the polynomials of the behavior curves of the pump in its design conditions to later correct the behavior based on a velocity of present operation.

    This work studies the contamination degree of the meso and infra-coastline sediments of the Baia de Todos os Santos, Bahia, the largest of Brazil, by organic compounds, mainly of period origin. The assessment was proceeded through quantification of total polycyclic aromatic hydrocarbons (PAH's), by fluorimetric analysis in continuous flow. The levels of contamination were quantified taking in consideration the levels considered as critical by the published literature. The grading of the target sites with those of the control sites (background) were compared also. The main objective was to define the degree of contamination relative to different areas of the bay, correlating with the different activities, such as oil exploitation, industrial production, mainly of oil processing at the north of the bay, port and urban, specially near the city of Salvador, with 2 million of inhabitants. In some stations, specially in those classified as industrial, urban and heavy boats traffic, sediments showed contamination, resulting in grades up to 2000 times greater than the control sites. Some regions, mainly industrial and urban, showed high PHA's contamination, higher than 200 {mu}g/g. The majority of sediments in areas remaining as recreational until present days showed no contamination, lesser than {mu}g/g. (author)

    The major projects concerning the dissemination of the use of photovoltaic solar energy (PVSE) in Brazil are located in the Northeast region. Particularly, the state of Pernambuco has the largest number of installations and the largest installed power of autonomous systems. There exist approximately 700 residencies, 250 schools and 150 water pumping systems among other applications using PVSE, totaling 250 k Wp installed in more than 80 cities of that State. This work analyses a diagnosis report on the state of functioning of 64 one-year-old water-pumping installations in 30 m to 60 m depth wells, driven by 300 to 1,600 Wp photovoltaic generators, the flows varying from 200 l/h to 6,000 l/h. Technical and non-technical problems were identified, ranging from improper location choice, wrong system dimensioning, inadequate photovoltaic generator installations, lack of user instruction and training, lack of responsibility definitions regarding the technical assistance and the needed follow-up. In the final part of this report proposals are enumerated concerning the establishment of a local and municipal organizing structure aiming the management of the water-pumping installations and the assurance of a larger success probability in the use of that technology.

    The inferior vena cava is the result of a complex embryologic process which takes place between 6 and 8 weeks of intra-uterine life. Several variations can occur during this process, and a defective embryogenesis of this vessel may lead to the development of anatomic variants. Although many of these variants are asymptomatic, the radiologist should be aware of them and of the potential medico-legal issues involved, especially in cases in which abdominal surgery or hemodynamic procedures are contemplated. In this paper, the major congenital anomalies involving the inferior vena cava are reviewed under the form of a pictorial essay, highlighting the role of the multiplanar imaging methods (volumetric computed tomography and magnetic resonance imaging) in their diagnosis.

    A new method for diagnosing the Campylobacter Pylori in the stomach is described, using C-14 settled urease. Campylobacter Pylori is now being considered the most probable causative agent of antral chronic gastritis, pepitic ulcer and non-ulcerous dyspepsia. The technique is based on ingestion of the tracer, its recovery by exhalation in etanol hyamine solution, followed by counting and dates evaluation. The test was applied to forty two voluntary male and female patients, after their written acquiescence. Their ages varied from 19 to 62 years old. Thirty of the results were positive and twelve negative. All of them were comproved by microbiological (cultura) and hystologycal studies of gastric biopsy gotten by gastroscopy. They were performed at the Gastroentherology Departament of the 'Hospital das Clinicas' that belongs to the Federal University of Minas Gerais. Repetitivity of the breath test was confirmed by repetition of the results in five positive patients and five negative ones. (author).

    Intranasal tumors are uncommon and in most cases are malignant, aggressive and with low to moderate potential for metastasis. Clinical signs are usually caused by progressive obstruction of the upper airways. The test cytopathological also is a diagnosis method, but the definitive diagnosis is made by histopathological. Computed tomography (CT) is recommended to treatment planning. A poodle was attended at the veterinary hospital with a clinical history of epistaxis and nasal and ocular secretions, seizures and severe dyspnoea. The animal underwent to radiographic examination of the chest and skull as well as helical computed tomography of the nasal cavity and brain before and after the administration of intravenous contrast. The CT findings revealed an expansive bilateral nasal cavity neoformation, with involvement of the retrobulbar space, right frontal sinus, brain and oral cavity, suggesting a neoplastic or an infectious process. The CT examination allowed the material collection, directly from the mass, to cytological examination, providing the diagnosis of carcinoma. CT also allowed the determination of the unfavorable prognosis of the patient and the treatment planning which not included the surgical excision of the neoformation. Although CT was not conclusive in the diagnosis of carcinoma, it was essential to accurately define the extent of the lesion, to guide the collection of material directly from the tumor and to determine the prognosis of the animal, proving to be an extremely useful tool in cases of tumors intranasal in dogs.

    Recently the radiolabelled anti microbic peptides has intended as new radiopharmaceuticals for distinguish a bacterial infection of a sterile inflammatory process through a diagnostic image. The ubiquicidine 29-41 (UBI), it is a fragment of an anti microbic cationic peptide located in the human skin whose sequence of amino acids is Thr-Gly-Arg-Ala-Lys-Arg-Arg-Met-Gln-Tyr-Asn-Arg-Arg. The objective of this study was to develop a derived of the UBI 29-41 radiolabelled with Tc-99m in high radiochemical purity and to evaluate the feasibility of using it in the specific detection of infectious focuses. The molecular structures of the UBI as well as of other 2 cationic peptides used as control (Tat-1-Scr and Tat-2-Scr), they were calculated and optimized in their more stable configuration by molecular mechanics procedures and quantum mechanics. Once established the site for the labelled with {sup 99m} Tc, the three complexes were represented by the general formula [Tc(V)(O)(H{sub 2}O){sub 2} (Lys{sub n=1,2}-Arg{sub n=0.1}-peptide)]{sup 10+,11+}, with potential energy of 104.5 Kcal/mol, 95.6 Kcal/mol and 90.8 Kcal/mol for the {sup 99m}Tc-Tat-1-Scr, {sup 99m} Tc-Tat-2-Scr and {sup 99m}Tc-UBI 29-41 respectively. The three radio complexes got ready experimentally and their stability in vitro saline solution is evaluated, human serum and cysteine solutions. The experimental results correlated appropriately with the calculated data. The specificity in vitro was carried out evaluating the percentage of union of the {sup 99m}Tc-UBI 29-41 as well as of the control peptides at bacteria of S. aureus and two tumoral cellular lines (LS174T and ACHN). The In vivo specificity was determined using Balb-C mice with induction in a paw of an infectious process and in another paw of a sterile inflammatory process. Simultaneously it was administered to the mice with infection and inflammation induced {sup 99m}Tc-UBI 29-41 and {sup 67}Ga-citrate this last an unspecific radiopharmaceutical used so much in the detection of infectious processes as inflammatory, obtaining the respective gamma graphic images. Once proven the specificity and non toxicity of the {sup 99m}Tc-UBI 29-41, their capacity of detecting infectious focuses obtaining images diagnoses in some osteomyelitis courses was evaluated. The results showed that the {sup 99m}Tc-UBI 29-41 can prepare it as a highly stable radio complex with radiochemical purity >97%. This radiopharmaceutical unites specifically to the bacteria so much in vivo as in vitro, while the control peptides unites as much to bacteria as to tumoral cells. The gamma graphic images showed a quick renal purifying with minimum accumulation in non target organs and a relationship in infection sites/not infected infected sites of 2.2{+-}0.7 at 2 hours. The {sup 99m}Tc-UBI 29-41 can prepare it by a direct method with high radiochemical purity and, for their properties of molecular recognition and biokinetics, to be used as a diagnostic agent for the specific detection of infectious processes.

    The development of new radiopharmaceuticals is an essential activity to improve nuclear medicine, and essential for the early and effective diagnosis of oncological diseases. Among the various possibilities current research in the world, the radiopharmaceuticals to chemotherapeutic base may be the most effective in detecting tumors, particularly Gastrointestinal Stromal Tumor (GIST), the Metastatic Renal Cell Carcinoma and neuroendocrine pancreatic tumors. However, difficulties in directing, as well as adhesion of the radiopharmaceutical in the desired location, are currently the main problems in the early detection and treatment of some of these tumors. Advances in the field of nanotechnology, particularly in recent years, indicate significant contribution to overcoming these obstacles, particularly in the implementation of molecular barriers as well as the functionalization of the nanoparticles, thereby improving targeting by the use of surface nucleotides, and the increased adhesion, which facilitates the release of the drug and therefore increases the chances of early diagnosis and more effective treatment. This study aimed to the production, characterization and evaluation of cytotoxicity, as well as in vivo biodistribution test Bevacizumab nanoparticles labeled with Technetium-99m radionuclide for detection of type GIST tumors. Bevacizumab was encapsulated in the form of nanoparticles by the emulsification method using double poly-acetic acid and polyvinyl alcohol polymers (PLA / PVA) at a concentration of 2% of the monoclonal antibody. The characterization of the nanoparticles was performed by the technique of scanning electron microscopy (SEM). The cytotoxicity assessment was performed by XTT assay with various cell lines of solid tumor cells. The labeling with technetium-99m was done by the direct method, and its yield determined by paper chromatography using paper Whatmam 1 as the stationary phase and acetone as mobile phase. In the biodistribution study, we used healthy Wistar rats killed 2 hours after administration. Organs were dissected for counting in the gamma counter. The SEM showed that the nanoparticles have spherical shape, with size dispersion of 180 to 200 nm. The cytotoxic effect of the nanoparticles was confirmed by the decrease of the viability of tumor cell lines MDA, MB-231, MCF-7 and A549 cells that express VEGF, from 500 mg / mL PLA / PVA / bevacizumab nanoparticles. Nanoparticles labelling had yield a higher than 99%. In the study of biodistribution with healthy Wistar rats it was observed an improvement in the biodistribution of the drug with decreased first-pass effect, making it more available in the blood, improved debugging and decrease in spleen and liver, with less involvement of the immune system. These results suggest greater safety and specificity of this nano radiopharmaceutical compared to the parent drug. (author)

    The current regulation, established by NOM-229-SSA1-2002 standard, {sup T}echnical requirements for facilities, health responsibilities, technical specifications for equipment and facilities for radiation protection in medical diagnosis with X-rays,{sup t}hat should be credited refresher courses, and training in radiation safety in accordance with current regulations, however, has been observed that the assistance and accreditation of courses is basically to cover administrative and regulatory requirements and therefore does not necessarily cover needs of the patient to radiation protection in the use of old and new technologies. David Brenner and Eric Hall claim that between 1.5 and 2% of all cancers in the USA may be attributable to exposure to X-ray computerized tomography techniques, given the intensive use of these techniques and the patient dose ranges in which incurred. While this is not debatable, if it is, the alternative does not seem to be abandoning the use of computerized tomography, because it gives them undoubted benefits with respect to invasive procedures. Deserves mention concerns the use of computerized tomography in children using scanning protocols designed for adults, in which case it incurs in 5 times higher dose. An additional warning about unwarranted use of computerized tomography is a procedure of this technique in abdomen resulting in an equivalent dose to 298 times that of a mammogram. Additional aspects such as biological effects (including deterministic) of both medical staff and patients of interventional procedures further reinforces the idea that there are education programs in radiation protection. Attention must put in the new generations, including in the curricula of medical residencies in radiology, endoscopy, cardiology and orthopedic, the education (no emerging courses) in radiation protection, radiobiology, radiology physics, and other topics, but previously must have medical physicists in radiology available to train new generations.

    Diagnosis of Mild Cognitive Impairment (MCI) can indicate an initial dementia framework, or increase in the likelihood of developing this. The PET/CT (positron emission tomography associated with computed tomography) has shown excellent prospects for MCI diagnosis. The PET/CT helps diagnosis, but the patients effective dose is higher, it depends on the computed tomography (CT) protocol and the radiopharmaceutical patient injected activity. This study evaluates the dose in 38 male patients undergoing this technique for MCI diagnosis. To assess the radiation level from CT modality imaging was used TLD100 detectors embedded in a male anthropomorphic Alderson Randon® phantom, undergoing the same imaging protocol to which patients were referred. The dose resulting of radiopharmaceutical injected activity was estimated using the ICRP106 model proposed. The PET / CT effective dose for producing image was (5.12 ± 0.90) mSv. The contribution to the effective dose due to the FDG brain incorporation was (0.12 ± 0.01) mSv and thyroid (0.13 ± 0.02) mSv. The effective dose contribution due to brain and thyroid CT irradiation was (0.18 ± 0.01) mSv and (0.010 ± 0.001) mSv, respectively. The use of optimized CT protocols and FDG injected activity reduction can assist in this procedure dose reduction. (author)

    To assess the sensitivity and specificity of magnetic resonance cholangiopancreatography (MRCP) as a noninvasive diagnostic technique, comparing it with endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTHC) in the diagnosis of biliary disease, focusing particularly on patients with choledocholithiasis. Between June 1997 and february 1998, 109 patients referred by the Corporacio Sanitaria del Parc Tauli and the Hospital Mutua de terrasa in Barcelona, Spain were evaluated. MRCP and ERCP or PTHC were performed in every case, always in that order and separated by a maximum of 7 days. Twenty-four patients were excluded from the study for different reasons, leaving a series of 85 patients. All the studies were performed with a 1-Tesla Siemens Magneton Impact Expert using half-fourier single-short turbo spin-echo (HASTE) and rapid acquisition with relaxation enhancement (RARE) methods in several coronal and axial planes. The MRCP readings were carried out by consensus by two radiologists who are experts in the assessment of diseases of the digestive tract. In this series of 85 patients; MCRP showed a sensitivity of 98.4%, a specificity of 94.7%, a positive predictive value of 98.4% and a negative predictive value of 94.7% for the detection of biliary diseases. For the detection choledocholithiasis, these values were 100%, 89.5%, 88% and 100%, respectively. MRCP is extremely reliable in the diagnosis of biliary diseases, especially in cases of choledocholithiasis. Its high negative predictive value obviates the need for other invasive diagnostic tests.

En primer lugar evaluaremos la importancia de estas empresas en España. A continuación, tomando como referencia los datos financieros de una muestra de empresas de los años 2004 y 2007, realizaremos un análisis estadístico de significatividad de las diferencias en rentabilidad, financiación, actividad, solvencia, inversión y presión fiscal, valorando también las posibles diferencias en los informes de auditoría emitidos. Por ultimo, exponemos los resultados alcanzados y constatamos su coherencia con la evolución económica experimentada por nuestro país en el periodo objeto de estudio, apreciándose un empeoramiento de la situación económico-financiera de las sociedades cooperativas. / In this paper we analyze the economic and financial performance of cooperatives in recent years, specially during 2004 and 2007, on the grounds that in the former of these years companies in general enjoyed a certain stability that disappears with the effects of the current economic crisis, and the latter as the year in which the effects of the crisis are beginning to be perceived globally in the business environment. First, we evaluate the potential importance of cooperative enterprises in Spain. Then, using financial data of a sample of firms for years 2004 and 2007, we carried out a statistical analysis of differences in profitability, financing, performance, solvency, investment and tax burden; also we assessed the existence of possible differences in audit reports issued for the period considered. Finally, we show the results which are consistent with the economic evolution experienced by our country in the period under review, in the sense that most of the financial indicators analyzed of cooperative enterprises are considerably worse in year 2007.

    To study the effectiveness of Doppler echography in the deep venous system of the lower limbs for deep venous thrombosis detection in patients suspected of having pulmonary thromboembolism. There were received 341 consecutive suspected pulmonary thromboembolism patients, all of whom were emergency room attended. All were submitted to CT pulmonary angiography in order to evaluate thrombus presence in the pulmonary tree. Without knowing the results of the previous exploration, we studied 301 of the patients using Doppler echography in deep venous system of the lower limbs in order to evaluate thrombus presence. In the group of CT-detected pulmonary thromboembolism patients, the percentage of Doppler echography-detected deep venous thrombosis was 46.3%, while in the group of non-detected patients this percentage decreased to 4.7%. Additional deep venous system exploration in clinically suspected pulmonary thiolcarbamate patients is useful, since it can increase the detection rate of venous thromboembolic disease, thereby leading to early treatment and prevention of the disease's manifestation in the lungs. Realization of Doppler echography is especially beneficial in those patients who exhibit no factors which predispose them to thromboembolic disease, as well as in patients who have previously had venous thrombosis. This exploration account for 4.7% of non-detected pulmonary embolism patients being added to the ranks of those with thromboembolic disease, an important percentage when taking into consideration the high pulmonary thromboembolism morbimortality rate.

    The supraspinatus muscle performs about 60 % of the elevation-abduction motion of the arm; it has a prominent functional role among the extra rotational muscles of the shoulder and is the most injured in subacromial space conditions. Seventy-four patients, aged 21-64 years, were examined to compare ultrasonography (US) results with surgical findings in supraspinatus conditions and to analyze the possible pitfalls in US diagnosis. All the patients underwent conventional X-ray US and then surgery or arthroscopy. The following criteria were considered: morphology, thickness, echotexture, the convexity of the superior border of supraspinatus tendon, the relationships with the subacromial bursa and the tendon of the biceps long head, the regularity of the bone cortex of the humeral head. US showed: perforating focal injuries in 21 patients; deep focal injuries in 10 patients; intramural focal injuries in 6 patients; superficial focal injuries in 8 patients; complete tendon tear with detachment in 19 cases. 62/74 US diagnoses were surgically confirmed, with a specificity of 83.7 %. In their experience, US provided very useful information about the pattern, size and site of the injuries and was very helpful in the surgical planning.

  5. Development of lutetium-labeled bombesin derivates: relationship between structure and diagnostic-therapeutic activity for prostate tumor; Desenvolvimento de derivados da bombesina radiomarcados com lutecio-177: relacao estrutura e potencial diagnostico-terapeutico para tumor de prostata

    Bombesin (BBN) receptors - in particular, the gastrin-releasing peptide (GRP) receptor peptide - have been shown to be massively over expressed in several human tumors types, including prostate cancer, and could be an alternative as target for its treatment by radionuclide therapy (RNT). A large number of BBN analogs had already been synthesized for this purpose and have shown to reduce tumor growth in mice. Nevertheless, most of the studied analogs exhibit high abdominal accumulation, especially in pancreas. This abdominal accumulation may represent a problem in clinical use of radiolabeled bombesin analogs probably due to serious side effects to patients. The goal of the present work was to radiolabel a novel series of bombesin derivatives with lutetium-177 and to evaluate the relationship between their structure and diagnostic-therapeutic activity for prostate tumor. The generic structure of studied peptides is DOTA-Phe-(Gly){sub n}-BBN(6-14), where DOTA is the chelator, n is the number of glycine amino acids of Phe-(Gly){sub n} spacer and BBN(6-14) is the bombesin sequence from the amino acid 6 to the amino acid 14. Preliminary studies were done to establish the ideal labeling conditions for obtaining the highest yield of labeled bombesin derivatives, determined by instant thin layer chromatography (ITLC-SG) and high performance liquid chromatography (HPLC). The stability of the preparations was evaluated either after storing at 2-8 degree C or incubation in human serum at 37 degree C and the partition coefficient was determined in n:octanol:water. In vivo studies were performed in both healthy Balb-c and Nude mice bearing PC-3 xenografts, in order to characterize the biological properties of labeled peptides. In vitro studies involved the evaluation of cold bombesin derivatives effect in PC-3 cells proliferation. Bombesin derivatives were successfully labeled with high yield at optimized conditions and exhibited high stability at 4 degree C. The analysis of the stability in human serum suggested a time-course metabolic degradation of labeled peptides by serum enzymes. The addition of four glycine amino acids in the spacer of bombesin derivatives resulted in slower degradation by human serum enzymes after 4 hours of incubation. HPLC and partition coefficient studies showed that bombesin derivatives present low lipophilicity and the increase of glycine amino acids number in peptides spacers slightly reduced their lipophilicity. The radiolabeled bombesin derivatives presented fast blood clearance, rapid excretion, performed mainly by renal pathway, and low abdominal accumulation in in vivo studies in Balb-c mice. Investigations in Nude mice bearing PC-3 tumor showed that the radio peptides can target tumor cells. Higher tumor uptake was observed with the derivatives of larger spacers at 1 hour post injection, but higher tumor retention after 4 and 24 hours was observed with the derivative of smaller spacer. In addition, tumor uptake showed to be specific and allowed tumor detection by scintigraphy imaging, especially 30 minutes post injection. In addition, the studied bombesin derivatives did not present proliferative or cytotoxic effect to PC-3 cells in vitro and can be characterized as weak agonists or antagonists of bombesin receptors. The results of this work showed that phenyl-glycine extended bombesin derivatives are promising for in vivo applications. The higher tumor uptake of derivatives with larger spacer suggests that these molecules are more applicable in diagnostic procedures. The derivative with smaller spacer is more useful to be applied in radionuclide therapy, because of its higher tumor retention. (author)

    Thanatophoric Dysplasia is a rare genetic disorder that leads to the normal growth of the individual leaving him with short stature deterrent. Patients with this syndrome have disproportionately short limbs, with extra skin folds, narrowing chest, small ribs, underdeveloped lungs and hydrocephalus. The Thanatophoric Dysplasia can be diagnosed by ultrasonography (US), with approximately 23 weeks of gestation. If there is suspicion of a lethal skeletal dysplasia CT with 3D reconstruction can be suggested. In the use of CT Multslice 3D for prenatal diagnosis of Thanatophoric Dysplasia, one should take into account the radiation dose. To reduce the radiation dose in the pregnant woman and her fetus, it is possible to employ a chain of smaller pipe without compromising the picture quality through automatic exposure control (AEC) which is based on the principle of CT Multslice. AEC Such systems are designed to adjust the tube current according to the patients shape, size, and attenuation of X-rays. One study compared the use of 2D-US and 3D-CT completion is lower cost and the absence of radiation in the US, the method is dependent on the volume of amniotic fluid and fetal position. The 3D-CT can demonstrate all fetal skeleton. The 2D US provided correct diagnosis in four of the six cases studied, while 3D-CT yielded the correct diagnosis in all six cases. (author)

    In the slaughterhouses the operations that if unchain in the one before slaughter until the storage of the end item are intensely dependents of the electric energy and answer for the final product quality. This work had as objective to diagnosis, to analyze and to consider solutions that lead to the rational use of the electric energy without intervening or keeping the product quality in the lines of production of one cold storage room of broiler including the storage process that uses chambers of cooling and freezing. This work was carried through in one cold storage room of slaughter of chicken situated in the state of Sao Paulo in the period of 2004 the 2008. Through the analyses it was verified that the compressors of the room of machines, responsible for the maintenance of the cold of cooled environments, had presented the biggest consumption of electric energy in the cold storage room, about 97%. It was observed that in none of the evaluated electric engines, the potency factor, reaches the value recommended for the ANEEL, and that possibly with the implantation of measures of conservation of electric energy pointers of energy efficiency as the load factor and the specific consumption they can be optimized. It was concluded to have imperfections in the use of the electric energy demonstrating necessity of the implementation of an action plan that aims at the conservation and the rational use of the energy and consequence reduction in the costs generated for production of broiler.

The early identification of unexpected departures from steady state behavior is an essential step for the operation, control and accident management in NPPs. The bases for the transient identification relay on the evidence that different system faults and anomalies lead to different pattern evolution in the involved process variables. During an abnormal event, the operator must monitor a great amount of information from the instruments that represents a specific type of event Several systems based on specialist systems, neural-networks, and fuzzy logic have been developed for transient identification. In the work, we investigate the possibility of using a Neuro Fuzzy modeling tool for efficient transient identification, aiming to helping the operator crew to take decisions relative to the procedure to be followed in situations of accidents/transients at NPPs. The proposed system uses artificial neural networks (ANN) as first level transient diagnostic After the ANN has done the preliminary transient type identification, a fuzzy-logic system analyzes the results emitting reliability degree of it. A preliminary evaluation of the developed system was made at the Human-System Interface Laboratory (LABIHS). The obtained results show that the system can help the operators to take decisions during transients/accidents in the plant (author)

    We describe three improved methods of detecting prostate cancer while it is still confined to the gland: Prostrate specific antigen (PSA), trans-rectal ultrasound (TRUS) and trans-rectal ultrasound-directed prostatic fine needle aspirate (TRFNA). Of a total of 60 studied cases, 23 cytological procedures were done, and half of these were found to have prostate cancer. We compare traditional methods like digital rectal examination and prostatic phosphatase acid with PSA and TRFNA. We conclude that these methods increase the sensibility and specificity of early prostate cancer detection.

    Despite the wide range of antineoplastic agents available, resistance of some types of cancer and toxicity to normal cells have been identified as the main causes of treatment failure and death. The lack of early and precise diagnosis is also responsible for reducing survival of cancer patients. In this context, the development of substances with low toxicity and therapeutic potential and/or diagnosis purpose, is the major tool in an attempt to increase the survival of patients and assure the safety and efficacy of treatment. Thiosemicarbazones (TSC) are a class of synthetic compounds that have several biological activities, including antitumor. Although several studies have shown the great potential of TSC as therapeutic and / or diagnostic agents, different chemical modifications performed on this class of molecules indicate new possibilities for applications and still require further studies. The objective of this study was to evaluate the potential applicability of 2-acetylpyridine N-4-phenyl thiosemicarbazones derivatives for cancer therapy and diagnosis. The results showed that all 13 TSC tested were cytotoxic to breast and glioblastoma tumor cell lines, presenting higher in vitro antitumor activity than etoposide, an antineoplastic and inhibitor of topoisomerase II frequently used for cancer therapy. The TSC that have halogen or nitro on ortho position showed higher antitumor activity in vitro than their isomers with halogen or nitro on meta or para position of the phenyl group. H2Ac4oFPh and H2Ac4oClPh compounds showed the highest antitumor activity among all tested compounds, with IC{sub 50} in nanomolar order. These TSC induced cell death by apoptosis and oxidative stress was responsible, at least in part, for this type of cell death. The 5 mg.kg{sup -1} H2Ac4oFPh dose, administered s.c., for 4 consecutive days, did not induce important toxicity; however, the same treatment protocol was not effective for tumor growth reduction in an animal model of brain tumor. Radioactive probes of H2Ac4oFPh were synthesized using {sup 111}In or {sup 67}Ga as radiotracers, with satisfactory specific activity and radiochemical purity. H2Ac4oFPh-{sup 111}In was more useful than H2Ac4oFPh-{sup 67}Ga, with higher specific activity, better chemical purity, better in vitro stability, higher distribution volume, faster blood clearance and, therefore, was considered the most promising for application in molecular imaging studies. H2Ac4oFPh-{sup 111}In also showed high lipophilicity and was internalized by glioblastoma cells in vitro. H2Ac4oFPh-{sup 111}In showed significative tumor uptake in vivo, however, the high abdominal uptake and high background did not allow a good visualization of tumor in imaging studies. Unlike intravenous administration, intratumoral administration allowed greater diffusion and retention of H2Ac4oFPh-{sup 111}In in the tumor site and significantly reduced the activity accumulated in the organs. These results encourage new experiments to be performed in order to promote the complexation of H2Ac4oFPh with particle emitters, such as yttrium-90, to evaluate its application in local radioisotopic therapy for glioblastoma multiforme.

    Lack of data regarding environmental matters in relation to the great majority of MSW landfills throughout Spanish territory makes it difficult to consider them suitable for exploitation or territorial expansion required for different activities demanded by society. The environmental risk of a landfill must be minimised with the help of environmental planning tools. One of these tools is based on the environmental diagnosis and characterisation of the areas affected by the solid waste deposit.. Diagnosis by means of quantifiable environmental indexes helped us in our work to determine the priorities for the environmental control of certain Spanish landfills. This diagnosis was used for creating the Observatory on Solid Waste Landfills, organized by ATEGRUS (Spanish Technical Association for Waste Management) in 2003 and presented at ATEGRUS 30th Annual conference on Controlled Landfills.

    The congenital hypothyroidism is an endocrine illness knows from the X V century. It is caused by the anatomical or functional absence of the thyroid gland, what causes a deficiency in the thyroid hormones production. These hormones are indispensable for an appropriate physical and mental development from the first moments of the life. This illness is the more frequent cause of avoidable mental retardation in the child. In Mexico, is considered that 1 of each 2,537 newborns present congenital hypothyroidism, this frequency is extraordinarily high in relation to other countries. For the opportune confirmation of this illness is carried out by means of the radio immuno analysis that is a competitive type technique which is based on the antigen-antibody reaction. To the present antigen in the sample problem, is go to add a constant and known quantity of labelled antigen (hot antigen). The labelled antigens are formed substituting some of the normal atoms of the antigen for the corresponding radioactive isotope I{sup 125} in the molecule. The two types of antigens, cold and hot will compete, in equality of conditions, to unite with the available antibody. The concentrations of labelled antigen and antibody not change, the only variable of the system is the non labelled antigen (cold antigen) concentration. As much as more it is the quantity of cold antigen in the sample problem, it is displaced at the hot antigen and therefore they are fixed to the antibody smaller quantities of labelled antigen. Therefore, the formation of radioactive complexes (Ag-Ac) it varies in function of the non labelled antigen concentration: to major non labelled antigen concentration, major formation of non labelled antigen-antibody complexes, and minor formation of radioactive complexes and vice versa. 29 cases were analyzed with suspicion of congenital hypothyroidism therefore the T4 neonatal and TSH neonatal were quantified by the radio immuno analysis technique giving the confirmation of a single positive case as result. In this way it is contributed to the opportune confirmation of the results provided by the neonatal sieve for the detection and opportune treatment in order to avoid the congenital hypothyroidism consequences.

    Fractures on the maxillofacial complex demand a detailed three dimensional comprehension of the damaged area. A correct radiographic evaluation is essential for the planning of the repair surgery. The surgical maneuvers involving this type of trauma depend on the knowledge of anatomy and an image diagnosis. The three dimensional images are especially important for the surgeons due to the fact that they allow a panoramic representation of the facial complex and of the fracture, facilitating the treatment planning. This study aims to report three clinical cases, as well as a literature review, discussing the utilization of three-dimensional tomography reconstructions on the diagnosis of the facial trauma.

    Pulmonary arteriovenous fistula is not clinically recognized until the patient reaches adulthood in most cases. The symptoms, when present may not be specific, and include hemoptysis, epistaxis and low oxygen saturation, among others. Plain radiography shows a round or oval lobulated mass of uniform density, an image that is often diagnostic since the arterial and venous vessels are visible. Contrast-enhanced helical computed tomography and magnetic resonance angiography are ideal techniques for pretreatment evaluation, showing the nutrient artery from the lung hilum and the draining vein toward left atrium. Excellent results are obtained with coil embolization. (Author) 8 refs.

    Conjoined twins have a rare prevalence and special curiosity among physicians and the general population. The reported frequency varies from 1:50,000 to 1:200,000 pregnancies. Its early diagnosis becomes very important when we think about pregnancy management, method of delivery and neonatal care. We describe two cases of conjoined twins diagnosed by ultrasound and magnetic resonance during prenatal care with the aim to better studying the fetus anatomy. The first conjoined twins were cephalopagus sharing head, thorax and abdominal wall and with two pelvis and four arms and four legs. The second were thoracopagus, united by thorax and part of abdomen. Magnetic resonance imaging contribution was not important to diagnose conjoined twins. However, it was useful to describe the shared organs, contributing to define fetal outcome. (author)

    The monitoring and diagnosis area is presenting an impressive development in recent years with the introduction of new diagnosis techniques as well as with the use the computers in the processing of the information and of the diagnosis techniques. The contribution of the artificial intelligence in the automation of the defect diagnosis is developing continually and the growing automation in the industry meets this new techniques. In the nuclear area, the growing concern with the safety in the facilities requires more effective techniques that have been sought to increase the safety level. Some nuclear power stations have already installed in some machines, sensors that allow the verification of their operational conditions. In this way, the present work can also collaborate in this area, helping in the diagnosis of the operational condition of the machines. This work presents a new technique for characteristic extraction based on the Zero Crossing of Wavelet Transform, contributing with the development of this dynamic area. The technique of artificial intelligence was used in this work the Paraconsistent Logic of Annotation with Two values (LPA2v), contributing with the automation of the diagnosis of defects, because this logic can deal with contradictory results that the techniques of feature extraction can present. This work also concentrated on the identification of defects in its initial phase trying to use accelerometers, because they are robust sensors, of low cost and can be easily found the industry in general. The results obtained in this work were accomplished through the use of an experimental database, and it was observed that the results of diagnoses of defects shown good results for defects in their initial phase.

    The number of medical examinations and procedures that use ionizing radiation have continuously increased in recently years. More than 90% of human-generated exposures to ionizing radiation are from medical uses and the collective dose due to patient exposures is 200 times greater than the occupational dose of exposed workers. At the same time, the emergence of new technologies, the increased use of Computerized Tomography (CT)-even for pediatric patients- the development of digital radiography, interventional radiology and the new technologies in nuclear medicine with the use of hybrid PET/CT and SPECT/CT equipment have all contributed as well to an increase in the doses received by patients. This poses a challenge to the regulatory authorities in the field of radiological protection, the goal of which is to makes sure that the risks to patients are as low as possible compared to the benefits yielded by the use of ionizing radiation for medical purposes, in accordance with ALARA criteria.

    To study the ultrasonographic findings in a series of patients with Crohn's disease (CD). The series consisted of 80 patients who underwent abdominal ultrasound over a three-year period for whom there was no prior knowledge of radiologic and/or endoscopic findings. The technique involved gradually applying pressure to the abdomen, and a thickening of the intestinal wall of 4 mm or more was considered indicative of disease. The localization, extension, lesions, activity and possible complications associated with the process were established definitively by endoscopy, intestinal transit, barium enema and/or computed tomography, depending on the type of intestinal involvement. Ultrasound disclosed the presence of inflammatory bowel disease in 71 of the 80 patients. Of these, 69 presented CD; the other two patients were finally diagnosed as having ulcerative colitis and infectious enterocolitis, respectively. The results of the study were considered to be normal in 7 patients in whom the disease was in an inactive phase. In 2 cases, ultrasound demonstrated the presence of acute appendicitis and histological examination confirmed it to be granulomatous appendicitis. Thickening of the bowel wall, proliferation of mesenteric fat, and ulcers and fissures in abdominal wall were the most common findings. The most predominant complications were fistulas, stenosis and abscesses. Ultrasound is a highly useful method for the diagnosis, assessment of activity, follow-up and detection of complications in this inflammatory bowel disease. Among the advantages are its low cost and the possibility of performing repeated studies without exposing the patient to radiation or the discomfort of endoscopy. (Author) 17 refs.

    This paper presents a methodology for assessing the social-environmental fragility of a watershed where there is potential for installation of hydropower projects. The method includes dividing the watershed into sub areas (by analysis of similar characteristics) and, subsequently, the use of 23 indicators grouped into six social-environmental components (Water Resources and Aquatic Ecosystems, Terrestrial Ecosystems and the Physical Environment, Territorial Organization, Way of Life, Economic Base and Indigenous Communities and Traditional Populations), which together seek to portray all aspects involved in the fragility of the area. The technique was applied in the basin of the Coxim river in the State of Mato Grosso do Sul, assuming that there is interest or the possibility of installing hydropower plants within its boundaries. The basin was divided into three sub areas, considering physical parameters (such as topography, rainfall and hydrology), which were ranked by calculating the fragility of each one of the social-environmental indicators. As a result, a map was created to indicate the sub areas more susceptible to damage and those which should be more resistant to the installation of impacting activities, such as hydropower plants. The use of Geographic Information Systems (GIS) and the work of a multidisciplinary team can reduce the degree of subjectivity of the methodology and allow, (by modifying some considerations inherent in the partial calculations,) its application in other situations where the possibility of installing hydropower projects is not considered.

    In order to assess the exposure of the Portuguese population to ionizing radiation due to medical examinations of diagnostic radiology and nuclear medicine, a working group, consisting of 40 institutions, public and private, was created to evaluation the coletive dose in the Portuguese population in 2010. This work was conducted in collaboration with the Dose Datamed European consortium, which aims to assess the exposure of the European population to ionizing radiation due to 20 diagnostic radiology examinations most frequent in Europe (the 'TOP 20') and nuclear medicine examinations. We obtained an average value of collective dose of Almost-Equal-To 1 mSv/caput, which puts Portugal in the category of countries medium to high exposure to Europe. We hope that this work can be a starting point to bridge the persistent lack of studies in the areas referred to in Portugal, and to enable the characterization periodic exposure of the Portuguese population to ionizing radiation in the context of medical applications.

    Maintenance Technicians, more and more, must dispose of predictive tools to diagnose the state of the equipment, especially if they are responsible for the emergency diesel in a Nuclear Power Plant. the use of these tools should be understood as a complement to more classic Preventive Maintenance of the equipment, thus increasing their availability because the parameters necessary for evaluating motor behaviour are taken while the engine is in operation. In this way, it facilitates the decision-making on whether to carry out certain preventive tasks. The basic information about this diagnostic tool presented in this article is based on the reading, recording and analysis of pressure, vibrations and acoustic emission in each engine cylinder during its operating cycle. A nice addition to the above diagnosis is carrying out and endoscopy of each cylinder, which enables the observation of: water leaks, injector leaks, the spraying of each injector, valve leaks,... etc. This article describes the fundamentals of a non-intrusive, easy to use and low cost tool, used to check the function of Emergency Diesel engines, as well as the experience of its use in the St. Maria Garona Nuclear Plant. The article also describes the case of a fault which occurred in the Nuclear Power plant in Garona that would hardly have been possible to detect by other means. This tool was developed jointly by the Engines Laboratory of the Department of Mechanical Engineering at the University of Zaragoza and the St. Maria Garona Nuclear Plant. It has been further improved, extended and optimized over the more than 10 years of its use. (Author)

    The need for a simple clinical test for singling out patients suffering from arterial hypertension due to renovascular causes has long been recognized. Over the past year, the authors have been using a linear scintillation scanner with ten detectors in parallel for delineating lesions within the kidney and estimating the rate of renal accumulation of {sup 203}Hg-labelled chlormerodrin. With this apparatus one can obtain very satisfactory renal images within two or three minutes after intravenous administration of 100 - 250 mCi of a radioactive drug. Scintigraphic images of both kidneys were obtained at 5, 10, 20, 30, 40, 50 and 60 min after administration of the radioactive compound without supression of the background radioactivity. All data were recorded on magnetic tape to permit subsequent selection of the technical parameters required for the reproduction of an image of optimum contrast and intensity. The pulse integrator included in the instrument was used to assess radioactivity in both kidneys during each scanning. Results were expressed as the ratio of renal radioactivity at a given time (C{sub t}) to renal radioactivity after five minutes (C{sub 5}); this value was called the renal concentration index (RCI). To distinguish bilateral renal ischaemia from essential arterial hypertension, the RCI of the right kidney (RK) was divided by the RCI of the left kidney (LK), which gave a comparative index for the two kidneys (I{sub comp}.). The authors conclude that the procedure as described could be used as a selective test for arterial hypertension of renovascular origin, since it furnishes an index directly correlated with the individual renal plasma flow and a series of images representative of the regional blood flow in each of the kidneys. As renal concentration of chlormerodrin requires both good renal blood flow and tubular cell efficiency, in cases of unilateral tubular necrosis results will be obtained similar to those for cases of unilateral renal ischaemia. The authors believe that in the study of arterial hypertension scintigraphic scanning should be carried out in conjunction with the plot of a curve showing renal concentration of chlormerodrin. This is to avoid possible errors due to differences in geometry of the two kidneys in relation to the detector. (author) [Spanish] Durante mucho tiempo se ha reconocido la necesidad de una prueba clinica sencilla que permita seleccionar a los pacientes cuya hipertension arterial tenga un origen renovascular. Durante el ultimo ano hemos empleado un centelleografo lineal con diez detectores en paralelo, para la delineacion de las lesiones localizadas en el rinon y para la estimacion de la velocidad de la concentracion renal de la cloromerodrina marcada con {sup 203}Hg. Este centelleografo nos permite obtener imagenes renales muy satisfactorias en 263 min, despues de la administracion endovenosa de 100 a 250 {mu}Ci del radiofarmaco. Despues de la administracion del compuesto radiactivo se obtuvieron imagenes centelleograficas de ambos rinones a los 5, 10, 20, 30, 40, 50 y 60 min, sin suprimir la radiactividad de fondo. Todos los datos fueron registrados en una cinta magnetica para posteriormente seleccionar los factores tecnicos necesarios para reproducir una imagen con cualidades optimas de contraste e intensidad. El integrador de pulsos, incluido en el instrumento, fue empleado para estimar la radiactividad en cada uno de los rinones durante cada exploracion centelleografica. Los resultados fueron expresados como la relacion de la radiactividad renal a un tiempo dado (C{sub t}) sobre la radiactividad renal a los 5 min (C{sub 5}), (C{sub t}/C{sub 5}); este valor fue denominado indice de la concentracion renal (ICR). Para diferenciar la isquemia renal bilateral de la hipertension arterial esencial, el ICR del rinon derecho (RD) fue dividido por el ICR del rinon izquierdo (RI), obteniendose un indice de comparacion entre ambos rinones (comp. I). Se concluye que el procedimiento aqui descrito puede ser empleado como una prueba filtro de la hipertension arterial de origen renovascular, pues ofrece un indice correlacionado en forma directa con el flujo plasmatico renal individual y una serie de imagenes representativas del flujo sanguineo regional en cada uno de los rinones. Como la concentracion renal de la cloromerodrina requiere tanto de un buen flujo sanguineo renal como de la eficiencia de la celula tubular, en los casos de necrosis tubular unilateral se obtendran resultados similares a los obtenidos en los casos de isquemia renal unilateral. En el estudio de la hipertension arterial creemos que el estudio centelleografico necesita ir acompanado del trazado de una curva de concentracion renal de la cloromerodrina para evitar posibles errores causados por diferentes geometrias de ambos rinones con respecto al detector.

    The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhino sinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic. So that, it is difficult to recognize nasossinusal disease in patients with cystic fibrosis. Questionnaire, nasal endoscopy and CT-scan are very important methods in this approach. Aim: to evaluate the diagnosis of chronic rhino sinusitis in patients with cystic fibrosis by anamnesis, nasal endoscopy and CT-scan and compare those results.Study Design: Clinical prospective. Material and method: evaluation of 34 patients - older than 6 years and with a confirmed diagnoses of cystic fibrosis - by anamnesis (questionnaire), nasal endoscopy (score Lund-Kennedy) and CT-scan (score Lund-Mackay). Results: chronic rhino sinusitis was confirmed in: 20,58% of cases by the questionnaire, 73,52% of the cases by the nasal endoscopy and in 93,54% of the cases by the CT-scan. The results showed significant differences. The correlation between nasal endoscopy score (Lund-Kennedy score) and CT-scan score (Lund-Mackay score) was statistically significant. Conclusion: the diagnosis of chronic rhino sinusitis was statistically different between the three methods. It was higher in imaging analysis and lower in questionnaire. The nasal endoscopy is an excellent method to evaluate nasossinusal disease in cystic fibrosis. (author)

    INGEOMINAS carried out this project in the cities of Cartagena, Bucaramanga, Cali and Bogota, in two phases: Phase 1 (Diagnostic) and Phase II (Formulation of Handling Plan). The phase 1 that here is described, it upgrades the knowledge of the extractive industry of the construction materials for the city of Cartagena, through bibliographical revision and field work, carried out in 50 quarries that supply from these materials to the city. This study, besides the economic and legal handling, identifies technical aspects related with the geology, the mining and the environmental situation. In accordance with their likeness, geologic, morphological and of exploitation (extraction methods and mining development), the quarries met in five groups: Exploitations on calcareous deposits of the La Popa Formation, exploitations on clay deposits of the La Popa Formation, exploitations on detritus deposits of half grain to thick (La Popa-Arenosa Formation; Pendales Conglomerate and Rotinet Formation) and exploitation of calcareous of the Arroyo de Piedra Formation. The extraction of these materials is characterized by its low degree of development technician, lack of planning mining, lack of appropriate infrastructure that allows a better development of the sector, is also evident the control lack on the part of the entities in charge of the handling of this industry. These factors added to a demand every time in increase of these materials, they have taken to a progressive deterioration in the landscape, increase of the noise and particles in the air and in the waters. The low control in this activity has generated the proliferation of informal exploitations that they find in this activity a way of subsistence.

    Full Text Available INTRODUÇÃO: A dismorfia muscular (DISMUS é uma síndrome psiquiátrica que acomete indivíduos de ambos os sexos com maior prevalência entre os homens, na qual o indivíduo percebe seu corpo como pequeno e franzino, quando na verdade é forte e musculoso. Inexistem na literatura abordagens antropométricas sobre DISMUS. OBJETIVO: Obter dados em uma população de referência para sugerir um critério antropométrico para diagnóstico da DISMUS. MÉTODOS: A amostra foi composta de 1.825 indivíduos que participaram de uma avaliação médico-funcional (1.108 homens e 717 mulheres entre os anos de 1994 e 2003, com idade superior ou igual a 15 anos, não atletas e que não apresentavam deficiência física locomotora significativa nem diagnóstico clínico de DISMUS. Foram calculados individualmente dois índices de proporcionalidade adimensionais, B/P1 e B/P2, com e sem correção pela medida de espessura de dobra cutânea, respectivamente. Estabeleceu-se como critério antropométrico para DISMUS a presença de uma razão superior a um entre os perímetros de braço contraído e flexionado e de perna associado à inexistência de três outros pontos de corte das variáveis ectomorfia, åDC (somatório das medidas de espessura das dobras cutâneas tricipital e perna medial e perímetro abdominal, esses últimos visando excluir indivíduos com valores de B/P1 e B/P2 elevados primariamente devido ao excesso de gordura corporal. RESULTADOS: Razão B/P1 > 1 foi observada em 16 indivíduos, oito em cada gênero. Analisando os outros pontos de corte, todas as mulheres puderam ser identificadas como obesas e, portanto, não portadoras de DISMUS, enquanto nos homens, sete dos oito indivíduos puderam ser enquadrados como casos sugestivos de DISMUS. CONCLUSÕES: Com base na amostra ampla e heterogênea utilizada no presente estudo, é possível sugerir um critério antropométrico como sinal de DISMUS. Outros estudos estão sendo conduzidos para validar o critério antropométrico de DISMUS proposto no presente estudo e determinar a sensibilidade e a especificidade utilizando amostras propositadamente escolhidas por sua alta prevalência de DISMUS.INTRODUCIÓN: La dismorfia muscular (DISMUS es un síndrome siquiátrico que ataca a individuos de ambos sexos con mayor prevalencia entre los hombres, donde cada individuo reconoce su cuerpo como pequeño y frágil cuando en verdad es fuerte y musculoso.

There are no anthropometric approaches in literature about DYSMUS. OBJECTIVE: To obtain data from a reference population in order to suggest an anthropometric criterion for the diagnosis of DYSMUS. METHODS: The sample was composed of 1,825 individuals who participated in a medical-functional evaluation (1,108 men and 717 women between years of 1994 and 2003, with ages higher or equal to 15 years, non-athletes and not presenting significant locomotive physical disorders or clinical diagnosis of DYSMUS. Two non-dimensional proportionality indexes B/P1 and B/P2 were individually calculated with and without correction through the measure of the skinfold thickness, respectively. The presence of a ratio above 1 between the contracted and inflected arm and leg perimeters associated to the inexistence of three other cut-off points of ectomorphy, åSKF (sum of measures of triceps and medial leg skinfold thickness and abdominal perimeter variables; these last ones with the purpose of excluding individuals with high B/P1 and B/P2 values primarily due to the excess of body fat. RESULTS: The ratio B/P1 > 1 was observed in 16 individuals, eight from each gender. Analyzing the other cut-off points, all women could be identified as obese and, therefore, not carrier of DYSMUS, while among men, seven out of eight individuals could be classified as suggestive DYSMUS cases. CONCLUSIONS: Based on the wide and heterogeneous sample used in this study, it is possible to suggest an anthropometric criterion to identify DYSMUS. Other studies are being conducted in order to validate the DYSMUS anthropometric criterion proposed in the present study and to determine the sensibility and specificity used in samples willfully selected due to their high prevalence of DYSMUS.

    Macroaggregated human-serum albumin particles labelled with either I{sup 131} or chromium-51 have been utilized to determine regional blood flow to the lungs in dogs and man. Following intravenous injection, the particles accumulated in the lung, permitting clear delineation of the lung fields by scintillation scanning. In patients with lung abscess, pneumonia, atelectasis, tumours and thromboembolic disease of the lung, there was a decreased accumulation of the radioactivity in the regions of the lungs involved. The technique was found to be clinically useful in the diagnosis of massive pulmonary emboli in man and in the demonstration of vascular occlusion in certain patients with cor pulmonale. Studies in dogs made possible the determination of the rate at which revascularization occurred following experimental pulmonary emboli. Scintillation scanning was carried out at various times after the removal of the experimental emboli. The circulation was restored through the lungs within a period of several weeks after the removal of chronic pulmonary emboli in dogs. Although aggregated human-serum albumin retained its antigenicity in rabbits, guinea pigs and dogs, extensive studies failed to reveal any antigenicity of the particles to man. Because of the rapid metabolism of the macroaggregated albumin particles, the radiation to the patient was well within permissible levels. The use of albumin of high specific activity permitted injections of small chemical quantities; consequently no cardiovascular effects, such as increases in pulmonary artery pressure, changes in electrocardiogram or respiratory rate, were noted. (author) [French] Pour determiner chez le chien et chez l'homme le flux sanguin vers les poumons, on a utilise des macroparticules d'albumine de serum humain marquee avec {sup 131}I ou {sup 51}Cr. A la suite d'une injection intraveineuse, les particules s'accumulaient dans les poumons, permettant ainsi de delimiter nettement les regions pulmonaires par scintigraphie. Chez les sujets atteints d'abces pulmonaires, de pneumonie, d'atelectasie, de tumeurs ou dethrombo- embolie des poumons, on observait une accumulation moins intense de la radioactivite dans les regions pulmonaires affectees. Du point de vue clinique, cette methode s'est revelee utile pour le diagnostic des embolies pulmonaires massives chez l'homme et pour la mise en evidence d'une occlusion vasculaire chez certains sujets atteints de coeur pulmonaire. Les etudes sur des chiens ont permis de determiner le rythme auquel une vascularisation nouvelle se produisait a la suite d'embolies pulmonaires induites. On a fait des scintigraphies a diverses reprises apres embolectomie. Chez les chiens, la circulation dans les poumons etait retablie dans les quelques semaines qui suivaient l'embolectomie. Si les macroparticules d'albumine de serum humain gardaient leur caractere antigene chez les lapins, les cobayes et les chiens, des etudes tres poussees n'ont pu deceler un tel caractere chez l'homme. Par suite du metabolisme rapide des macroparticules d'albumine, la dose de radioactivite recue par les sujets restait bien en deca des niveaux admissibles. L'emploi d'albumine a forte activite specifique permettait de faire des injections de petites quantites de produit chimique; de ce fait, on n'a pas releve d'effets cardio-vasculaires, tels que des augmentations de la tension dans l'artere pulmonaire, des modifications de l'electro-cardiogramme ou du rythme respiratoire, etc. (author) [Spanish] Los autores utilizaron macroagregados de particulas de seroalbumina humana marcada con {sup 131}I o con {sup 51}Cr para determinar el caudal sanguineo regional que afluye a los pulmones en el perro y en el hombre. Inyectadas por via intravenosa, las particulas se acumulan en el pulmon y permiten delinear claramente los campos pulmonares por exploracion centelleografica. En pacientes con absceso del pulmon, neumonia, atelectasia, tumores y tromboembolias pulmonares, se observo una acumulacion disminuida de radiactividad en las regiones afectadas. Se comprobo la utilidad clinica de esta tecnica para diagnosticar embolias pulmonares masivas en el hombre y para descubrir oclusiones vasculares en ciertos pacientes afectados de cor pulmonale. Los estudios en perros permitieron determinar la rapidez con que progresa la revascularizacion despues de una embolia pulmonar experimental. Se efectuaron varias exploraciones centelleograficas una vez retirados los embolos experimentales. La circulacion se restablecio en todo el pulmon algunas semanas despues de haber eliminado los embolos pulmonares cronicos en los perros. Los agregados de seroalbumina humana han conservado su poder antigenico en los conejos, los cobayos y los perros, pero los estudios realizados no han permitido comprobar que las particulas tengan poder antigenico alguno en el hombre. Gracias al rapido metabolismo de los macroagregados, la dosis de radiacion recibida por el paciente se mantiene bastante inferior a los valores admisibles. El empleo de albuminas de elevada actividad especifica permite limitar considerablemente las cantidades inyectadas; no se observan, por lo tanto, efectos cardiovasculares tales como aumentos de presion en la arteria pulmonar, ni alteraciones del electrocardiograma o del ritmo respiratorio.

    The thesis work develops a methodology to determine when it is convenient, technically and economically to provide maintenance to a thermal electric unit and the type of maintenance to be performed, all this sustained in an economic analysis taking into account the variation of the production costs, of the interest rates, of the fuel prices and of the electric energy prices, the maintenance costs and the degradation of the unit in the time. Once analyzed the previous matters a thermo-economic test model and reference (values provided by the manufacturer) is performed and they are compared to determine in what equipment or system of the process of electric energy generation is required to focus on the material resources as well as on the human resources, in order to obtain the best results from the maintenance and recover the greatest possible efficiency of the unit. [Spanish] El trabajo de tesis desarrolla una metodologia para determinar cuando conviene, tecnica y economicamente proporcionar mantenimiento a una unidad termica y el tiempo de mantenimiento a realizar, todo esto sustentado en un analisis economico tomando en cuenta la variacion de los costos de produccion de las tasas de interes, de los precios del combustible y de la energia electrica, el costo de mantenimiento y la degradacion de la unidad en el tiempo. Una vez analizado lo anterior se realiza un modelo termoeconomico de prueba y referencia (valores proporcionados por el fabricante) y se comparan para determinar en que equipos o sistema del proceso de generacion de energia electrica se requiere enfocar tanto los recursos materiales como humanos, con el fin de obtener mejores resultados del mantenimiento y recuperar lo mayor posible la eficiencia de la unidad.

    This work shows the steps for implementing a program of rational use of electricity in a pine sawmill processing through energy diagnosis and also provide an energy efficiency index, the reference consumption in Kw.h power and volume of timber in cubic meters. The study was conducted in a sawmill located at Itapeva, southwest of Sao Paulo. The region's economic potential is based on the processing of wood with the main export destination. Much of the lumber does not have advanced technology, because it may present with excessive spending power. The species used are Pinus elliottii and Pinus taeda. We collected data on the electrical installation of the mill and the main parts of the installation as tables and distribution lines and equipment engines were studied. The diagnostic results show that while the industry had a good general appearance, electrical installations and equipment using electric power for its functioning need more care, both in maintenance and in use. An energy efficiency program, if effected, could reduce the cost of the process and provides environmental benefits by less need for electric power generation. (author)

    The aim of this study was to evaluate the methods for establishing dental caries diagnosis that make use of Laser light as source of illumination, establishing the 'state of the art'. Experimental observation of the differences among fluorescence of sound, demineralized and carious enamel by visible luminescent spectroscopy was also done. Six human teeth, extracted for clinical reasons were studied, and the results showed that the spectrum of carious enamel is different from the sound and demineralized ones. The differences are more evident relative to sond enamel and carious enamel, the same occurring between demineralized and carious enamel. The review of the literature aimed to make comparative considerations between QLF, LF and DELF; their effectiveness relative to traditional methods such as visual, visual with probe, radiography. It was verified that DELF was more sensitive, but could not discriminate between different degrees of mineral loss. QLF, compared to DIAGNOdent has the same sensitivity, but it is better for scientific purposes. The experimental part of the present study used on argon ion Laser to illuminated the teeth and signs of emission of fluorescence were captured by a PMT and then analyzed by a computer system with EG and G software. The results showed that the spectrum of carious enamel is different from the sound and demineralized. The differences are more evident in relation to sound and carious enamel, the same occurs between demineralized and carious enamel. (author)

    Radiopharmaceuticals of third generation by its design that includes peptides capable of selectively directing the radiation to a specific molecular target are useful in molecular medicine for obtaining molecular images that allow recording in vivo phenomena temporal-space of molecular or cellular processes, with diagnostic or therapeutic applications. Generally, peptides that recognize cellular receptors that are over-expressed in cancer cells of interest are used; such is the case of RGD (arginine-glycine-aspartic acid) a tri-peptide sequence which recognizes to the membrane receptors α(v)β(3) and α(v)β(5) that are involved in metastasis and angiogenic processes as well as in tumor cells of breast glioma. The high affinity and selectivity of RGD peptide with integrin s α(v)β(3) and α(v)β(5) is the basis for designing radiopharmaceuticals for diagnostic of breast cancer and the metastasis and angiogenic processes. In this paper a useful lyophilized formulation was development for obtaining {sup 68}Ga-DOTA-E-[c(RGDfK)]{sub 2} radiopharmaceutical that for its effectiveness, stability and security can be used in humans. The production process of core-equipment DOTA-E-[c(RGDfK]{sub 2}/Buffer sodium acetate 1.0 M was optimized, and the formulation was transferred to the radiopharmaceuticals production plant of the Instituto Nacional de Investigaciones Nucleares (ININ). The optimized formulation of the core-equipment for the {sup 68}Ga-DOTA-E-[c(RGDfK)]{sub 2} radiopharmaceutical preparation is: DOTA-E-[c(RGDfK)]{sub 2} peptide - 75 μg; Mannitol - 50 mg; Sodium acetate - 14 mg; Sodium acetate buffer 1.0 M ph 4.3 - 0.5 m L. The production process was validated and stability studies were carried out to the validation batches in compliance with the validation master plan of the ININ and in adherence to compliance of the applicable national and international regulations. Also the legal dossier was drawn up in order to make the application of sanitary registration before Comision Federal para la Proteccion contra Riesgos Sanitarios (COFEPRIS). (Author)

    To determine the efficiency of an early diagnosis programme using ultrasounds (US) of development dysplasia of the hip (DDH), using different criteria to delect patients according to the sex: universal to girls, but only including boys with a DDH risk factor (a physical pathological examination of new born babies, babies born feet first, family history and orthopaedic deformities). Of the 3,469 children born at our hospital during one specific year, 1,721 were included in the programme. US was carried out on all of them, following the Graf technique, when they were a month old, with the exception of the new born babies who were studied during their first week by means of a physical pathological examination. The babies who were diagnosed with physically immature hips in this first study using US; were followed up. Thirty-two babies born during the year suffered from DDH (a rate of 9.2 per thousand). Among them there was only 1 case of delayed DDH (that was not detected in the programme). Seven babies were diagnosed with DDH thanks to the follow up procedures carried out on babies with physically immature hips. Putting this programme for early diagnosis into practices has achieved the almost total disappearance of delayed DDH. When comparing the results with previous periods, where different early detection systems were used, the duration and the aggressiveness of the treatment has reduced considerably. Follow up procedures using US of physically immature hips is obligatory. (Author) 14 refs.

    Computed tomography (CT) is an important method of diagnostic imaging has been widely used around the world. However, this important diagnostic tool has led to a considerable increase in the frequency of examinations, often without proper clinical justification. Consequently, CT is one of the diagnostic procedures that contributes most to the collective dose. Scientific studies show that the concern in pediatric procedures should be even higher. Despite the fact that these patients have a higher radiosensitivity and a higher life expectancy, the protocols of the examinations are not optimized and adult protocols are applied. Moreover, a recent study performed in the United States showed that one third of the examinations was not justified. The aim of this study was to conduct a pilot study of dose indicators in pediatric CT in four hospitals, in order to verify the feasibility of the diagnostic reference levels establishment for the county of Rio de Janeiro. The dose descriptors were estimated from the beam dosimetry by applying the protocols used in each examination. The total patient sample included 358 children of different age groups. The results observed in examinations of whole trunk (routine chest, upper abdomen and pelvis) and upper abdomen in Institution A, for patients aged 5-10 years, indicated that the mAs values used were not properly selected for patients' body mass index, presenting however, conformity with UK reference levels. In the case of head CT scans and routine chest CT scans in Institution B, although patients aged 5-10 years have shown conformity with UK reference levels, the kV and mAs values used, in some examinations, were also inappropriate for the patient characteristics. Similar result was observed in examinations of head and high resolution chest for patients neonates, in Institution D. For head and routine chest examinations of 1-5 years' age group, was Institution B that showed the lowest DLP values. This result was due to the lowest CTDlyol values found therein. Comparisons of DLP values among institutions, for each age group in each kind of examination, also allowed observe a mean difference of 2248% in the Institution A's values in relation to the Institution D's values, for high resolution chest examinations of the 5-10 years age group. These results indicate that few efforts are being devoted to radiation protection in pediatric computed tomography, there is a high potential for optimization and that to establish tomographic good practices is essential the determination of diagnostic reference levels.

    This paper presents an evaluation of tissues and organs absorbed doses as well as the effective dose resulting from PET-CT scans performed with {sup 18}F-FDG radiopharmaceutical for lung cancer diagnosis in whole body scans. The ICRP-106 biokinetic model was used to estimate the absorbed and effective doses from the radiopharmaceutical for both male and female patient according to the characteristics of anthropomorphic Alderson Rando® simulators. Computer Tomography doses were evaluated using thermoluminescent detectors inserted in the same anthropomorphic simulators. Optimization protocols for image acquisition and the use of automatic exposure control were used in order to reduce patient doses, taking into account the equipment model and its system. The effective dose in female patients was 5.8 mSv. The effective dose in male patients was 8.4 mSv. The dose values estimated for the {sup 18}F-FDG PET-CT scan are below the values described in the literature. This is because the CT was not used for diagnostic but for morphological mapping.

    Recent advances in pharmacology, diagnostic and invasive procedures provide a series of modalities that diminish the morbidity and increase the long term survival in the patients that have suffered a heart attack to myocardium. The stratification by risk is an essential element for the handling of the survivors of heart attack to myocardium. In their attention it is looked for to optimize the therapeutic benefit, to diminish the unnecessary diagnostic and therapeutic procedures and to improve the efficiency. For example, a coronariography in sick with heart attack to myocardium it is not cost-effective if not is clinically suitable. Of there that from the institutional point of view, this is, of the Mexican Institute of the Public Health, they are required of appropriate reference approaches and counter reference to grant to the sick person, the best service that is the one in this case the diagnostic and the handling of the ischemic cardiopathy with the smallest waste of resources. The estimation of the annual survival is the base of the stratification, it constitutes the angular stone of the early handling of the heart attack to myocardium. The goal for the clinical would be to identify patients with intermediate risk, since, this risk makes them candidates to therapy interventionist. As long as those with low risk won't require intervention. This would allow the decrease of rates by revenues of heart attack to myocardium, and therefore to diminish the hospital staying rates. The Nuclear Cardiology (myocardial gammagraphy) it is not the only invasive method available to evaluate the myocardial perfusion in sick in who coronary illness is suspected. When the myocardial gammagraphy is carried out in appropriate population, the cost it diminishes because it restricts the necessity of additional invasive evaluations. This because the nuclear cardiology has predictive value so much for the mortality like to detect myocardial viability. Based on these probabilities, the doctor it could recommend diagnostic tests more sensitive and by this more cost-effective. The goal of this study was to design a model that compared cost-effectiveness of the gammagraphy in the diagnosis of the coronary illness by means of computed tomography by emission of simple protons (SPECT).

    The present study aimed to develop a radiopharmaceutical consisting of an emitter positrons radionuclide ({sup 68}Ga) which is used in imaging by positron emission tomography; and a peptide capable of binding to somatostatin receptors subtypes 2, 3 and 5; which together serve as a diagnostic support of tumors of neuroendocrine origin. The peptide characterization DOTA-1-Naphthylalanine{sup 3}-Octreotide (DOTA-NOC) by infrared spectroscopy technique by Fourier transform was performed, in which the principal functional groups belonging to this molecule were identified as well as its identification by UV-Vis spectroscopy. Subsequently, a variance analysis taking into account three different levels of amounts of sodium acetate, and three different levels of amounts of the peptide was performed. These masses were subjected to lyophilization for a period of 21 h; after completion of lyophilization, were labeled with 2 m L of {sup 68}GaCl{sub 3} eluates of a {sup 68}Ge/{sup 68}Ga ITG generator to determine the percentage of radiochemical purity of the different formulations. It was observed that the ideal formulation must contain 75 μg of peptide and 14 mg of NaOAc, according to studies, was determined that the amount of peptide does not influence the response of radiochemical purity in the same way that the amount of added sodium acetate, which produces different effects on the dependent variable. Finally the radiopharmaceutical formulation was obtained with greater than 95% of radiochemical purity. The validation of the analytical method was performed describing the system accuracy and linearity, specificity and accuracy; linearity and precision of the method, taking into account acceptance criteria based on the guidance of validation of analytical methods published by the National Association of Pharmacists Chemical Biologists of Mexico, A. C.; the parameters evaluated met the specifications given by the guide validation of analytical methods. Uptake and internalization tests of the radiopharmaceutical in AR42J cells were performed, obtaining significant differences in both tests, indicating affinity of the radiopharmaceutical by cells, because they exhibit over expression of SST R2 and 5 receptors. The report of the validation of the production process of the formulation was issued based on the established of the NOM-241-SSA1-2012. (Author)

    Objective: to determine the usefulness of magnetic resonance cholangiopancreatography (MRCP) in the diagnoses of bile duct injuries following cholecystectomy. Material and method: MRCP was retrospectively evaluated in 40 patients with suspected bile duct injury after laparoscopic or conventional cholecystectomy. Eight of these patients had been submitted to biliary reconstruction. All patients were symptomatic (jaundice, fever and chills, weight loss and abdominal pain). The scans were independently reviewed by two radiologists. The results were confirmed by surgery, percutaneous drainage, endoscopic retrograde cholangiopancreatography and clinical follow-up. The level and severity of bile duct injury were rated according to the Bismuth classification. Results: in a total of 40 symptomatic patients, 10 (25%) had normal findings on MRCP; Postoperative complications were seen in 29 (72.5%) patients, seven of them with more than one finding. Pancreatic head neoplasia was diagnoses in one patient. The most frequent finding was sclerosing (41.4%) followed by biliary duct stenosis (34.5%), residual or recurrent biliary stones (31.0%) and fluid collections (17.2%). The images obtained by MRCP were considered of good quality. Conclusion: MRCP is an effective method for the evaluation of patients with suspected postcholecystectomy biliary tract complications.

    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.

    The labeling of Ixolaris with {sup 99m}Tc was developed by Barboza et.al. (2013) aiming its use primarily in glioblastoma and after in melanoma diagnosis, a less common but very aggressive cancer and with high mortality rate. Preliminary tests on animals have proven its effectiveness of labeling but a dosimetric study to human clinical trials should be performed. This study aimed to: (1) determine the biokinetic model for the radiotracer {sup 99m}Tc-Ixolaris in mice by imaging dosimetry method; and (2) estimate the absorbed and effective dose resulting from the use of a new radiopharmaceutical for melanoma and metastases diagnosis in human beings, since a dosimetric study of new radiopharmaceuticals in animals is necessary to test them subsequently in humans and apply for registration in ANVISA. According to SPECT images, was found a latency period of 15 to 21 days for the development of lung metastasis in mice. Three C57BL6 mice, one control animal, and two animals with induced cell line B16-F10 murine melanoma were tested. The {sup 99m}Tc-Ixolaris radiopharmaceutical was administered intravenously in a caudal vein, and SPECT images were acquired 0.5 h, 1.5 h, 2.5 h, 3.5 h and 24 h post-administration for analysis and biodistribution quantification. The biokinetic model was determined and thus, obtained cumulative activity in order to estimate the absorbed dose in each organ. The mass and metabolic differences between mice and humans were considered and used to extrapolate the data acquired at different scales. Based on dose factors provided by the software MIRDOSE and Olinda (S factor), absorbed doses in irradiated target organs were calculated for the source organs, and finally the effective dose was estimated. The results indicate that for diagnostic exams conducted in human melanoma patients by administering approximately 25.7 MBq the estimated effective dose was 4.3 mSv. Comparing with effective doses obtained in other diagnostic techniques with {sup 99m}Tc, a range of effective doses from 0.6 to 4.8 mSv, it was concluded that the procedure should proceed continue into a Clinical Phase in humans.

    The question of components reliability, specifically process control valves, has become an important issue to be investigated in nuclear power plants and other areas such as refinery or offshore oil rig, considering the safety and life extension of the plant. The development of non intrusive monitoring and diagnostic method allows the identification of defects in components of the plant during normal operation. The objective of this dissertation is to present an analysis and diagnosis of control valves of a steam plant part that simulates the secondary circuit of a pressurized water reactor. This installation is part of propulsion equipment testing laboratory of the Brazilian Navy, at Ipero-SP. The methodology for design is based on graphical analysis of two parameters, the valve air pressure actuator and the displacement of the valve plug. These data are extracted by a smart positioner, part of Delta V™ Automation System. An analysis is implemented in detecting anomalies by an approach using Expert Systems by the technique of fuzzy logic. Once the basic measures of control valves are taken, it is possible to detect symptoms of failure, leakage, friction, damage, etc. The monitoring and diagnostic system has been designed in MATLAB® version 2009{sup th} by the complement 'Fuzzy Logic Toolbox'. It is a noninvasive technique. Thus, it is possible to know what is happening with the chosen components, just analyzing the parameters of the valve. The software called ValveLink® (developed by Emerson) receives signals from hardware component (intelligent positioner) installed next to the control valve. These signals (electrical current) are transformed into information which are used input parameters: air pressure valve actuator and valve plug displacement. With the use of fuzzy logic, these parameters are interpreted. They suffer inferences by rules written by experts in valves. After these inferences, the information is processed and sent as output signals. These signals lead to diagnostic information of the state of the valve. (author)

    The investigated area involves the Pipeline Row of Bolivia Mato-Grosso, inserted in the South-center of The Serrana Province (Almeida, 1964). The south-center section of Serrana Province is a water divisor from those that leaks west directly to Paraguay River from the waters that leaks on the east side to Pantanal. This work has as main subject, to diagnose and to value the environmental impacts that occurred and can occur in the future on the brooks and springs where there were Pipeline Bolivia Mato-Grosso interference on its crossing at the Serrana area, in Caceres municipality. The springs monitor were done during 18 months (march, 2001 to September, 2001), during and after the ending of the works, including different climates and hydrologic conditions, making it possible to diagnose and to value the draining behavior on the drought and on the overflow epoch. So, we believe that the knowledge about the interferences, risks and alterations that reflects on the fluvial duct of the sub-basin that drains the Serrana Province and leaks to Paraguay River may be contributing indirectly or directly to the Pantanal conservation.

    The World Health Organization recommends the direct immunofluorescence test for laboratory diagnosis and serological evaluation of rabies. To achieve this test, fluorescent anti-ribo nucleoproteins (RNPs) conjugates, produced from purified IgGs of RNP-immunized animals are employed. The aims of the present study were: investigate the effects of gamma radiation on the immunogenicity of RNPs, as well as to compare two chromatographic methodologies for the purification of anti-RNPs immunoglobulins. Sera from animals immunized with either native or irradiated RNPs were compared by direct immunofluorescence and immuno enzymatic assays. Our results indicate that the animals immunized with irradiated antigen requested a lower number of doses to reach high antibody titers. The immunofluorescence assays indicated that the conjugates produced with the anti-irradiated RNPs IgGs showed similar specificity to its anti-native counterpart, but with a higher definition of the virus inclusions. The purification methods were compared by Bradford and electrophoresis assays. According to the results, we concluded that the affinity-based process resulted in higher yields, lower execution time, and higher purity of the antibodies. (author)

    Full text: This paper is an approach to an increasingly complete knowledge about the nature of the processes that occur during a simple examination of radiological diagnosis; know as X-rays are produced and how they will put their energy into the tissue of patients when they are subjected to an examination of radiological diagnosis. First, using the MCNP code an X-rays tube was simulated, where electrons are emitted from a filament (cathode) which travel a certain distance with a certain kinetic energy and then be stopped suddenly in the tungsten target. The X-rays emitted as a result of this interaction, are previously filtered through the inherent filter of Pyrex glass and then by a thin aluminum foil before quantification as an X-rays spectrum. 6 spectra (for 60, 80, 100, 120 and 140 KeV) were obtained. Second, using the Penelope code was simulated the interaction of the X-rays spectrum, obtained in the first part with human tissue, putting as simile of human tissue water phantoms of different thicknesses. As final result: dose of energy deposited (in 2 and 3-dimensional) and reflected, absorbed and transmitted photons spectra. (Author)

    Cancer has killed millions of people worldwide. Despite the increasing knowledge about the molecular basis of tumor development, few advances have been reached in clinical therapy and diagnoses, which shows the importance of new drugs development for therapeutic and diagnosis purpose. Venomous creatures have been studied as potential sources of pharmacological agents and physiological tools. A lot of work has been done about biological activity of terrestrial animals, but comparatively less research has been undertaken on venomous marine creature, particularly fish, which means that marine toxins represent a vast and unexplored source of novel molecules with therapeutical potential. In this work, the scorpion fish Scorpaena plumieri crude venom (SPB) and a gelatinolytic protease purified from this venom (SPGP) were evaluated for their applicability for in vivo tumor detection. In vitro results showed that both. SPB and SPGP, possess a powerful antitumor effects on p53-wild-type glioblastoma cells (LD{sub 50}= 3,9 {+-} 0,98{mu}g/mL and 8,00 x 10{sup -12} {+-} 2,94 x 10{sup -12}M, respectively) and Ehrlich ascites carcinoma cells (LD{sub 50}=14,05 {+-} 2,95 {mu}g/mL and 1,22 x 10{sup -11} {+-} 6,56 x 10{sup -12}M, respectively). P53 mutant glioblastoma cells were more resistant to both, SPB and SPGP treatment (LD{sub 50} > 125 {mu}g/mL and LD{sub 50} > 1,39 x 10{sup -9}M, respectively). The morphological changes observed in the cell lines treated with SPB and SPGP, and the data of DAPI staining, indicate that the antitumor effect of these substances occurs via apoptosis. Radioactive probes of SPB ([{sup 99m}Tc] SPB) and SPGP ([{sup 125}I] SPGP) with high specific activity and high radiochemical purity were synthesized. Data of biodistribution studies, performed by intravenous injections in Swiss mice bearing Ehrlich carcinoma cells, showed that SPB has poor uptake in tumor region. On the other hand, SPGP had a substantial uptake in tumor at ali analyzed times. Intratumoral administration of [{sup 125}I]SPGP increased its uptake by the tumoral region and substantially reduced the uptake by other organs. Biodistribution studies in animals with edema confirmed that SPGP presents longer residence time in tumoral region than into inflammation site. Hematologic and histopathologic studies showed that SPB and SPGP did not present acute toxicity, even at concentrations ten times higher than those used in biodistribution studies. These results indicate the potential of SPGP as template for the development of new drugs and radiopharmaceuticals for tumors diagnosis and therapy. (author)

    The objectives of this study are to establish a strategy to monitor and diagnose vibrations of the motor pumps used in the primary reactor cooling system of the IEA-R1 nuclear research reactor, to verify the possibility of using the existing installed monitoring vibration system and to implement such strategy in a continuous way. Four types of mechanical problems were considered: unbalancing, misalignment, gaps and faults in bearings. An adequate set of analysis tools, well established by the industry, was selected. These are: global measurements of vibration, velocity spectrum and acceleration envelope spectrum. Three sources of data and information were used; the data measured from the primary pumps, experimental results obtained with a Spectra Quest machine used to simulate mechanical defects and data from the literature. The results show that, for the specific case of the motor-pumps of IEA-R1 nuclear research reactor, although the technique using the envelope of acceleration, which is not available in the current system used to monitor the vibration of the motor pumps, is the one with best performance, the other techniques available in the system are sufficient to monitor the four types of mechanical problems mentioned. The proposed strategy is shown and detailed in this work. (author)

    This article is based on an assessment that indicates the low effectiveness of the actions and programmes of social responsibility to the less impact than in business and should not build the value they expected. Focussing on this issue in cases of relationship between oil and gas companies with fishing communities, the scene of conflict is chronic and there is a fragile relationship in terms of confidence. It has been further that the approaches and methods commonly used are not properly aligned to the realities and characteristics of artisanal fisheries. In this context, we present an innovative process of relationship between the company El Paso Oil and Gas of Brazil and fishing communities in the region of Baixo-Sul, Bahia. The strategy used effectively consolidated the relationship of confidence between the company and the fishing communities around the area of exploration, rescuing the self-esteem, alleviate the marginalisation and making visible a productive sector of extreme importance. Furthermore, the capabilities and skills, both communities as the government and other companies to take more solid and ongoing commitments in the process of co-management require specific efforts in the strengthening of an institutional arrangement and the formation of social capital to continue advancing in concept work.

    From 1995, Spanish safety legislation has been adapted to the International framework. However, operationally the situation is not so good, at least in the wood harvesting activity. Some forest workers are still found not wearing the compulsory safety equipment, working without respecting safety rules and references to high accidents rates are frequent. To assess those aspects, firstly some comparisons have been made between the accident records in a reference company and the accident indexes at national and regional level for building and farming activities. Secondly, using a purpose-designed questionnaire applied to 35 logging work sites in Castilla y Leon Region, deficiencies in prevention have been identified. The relation between the accident reduction and the prevention methods used by the reference studied company has been confirmed. Also the main causes of the accidents have been analysed. Finally, some recommendations to reduce the risk of accidents in harvesting operations are provided. The main conclusion confirms that the possibility of reducing the accident risk is conditioned to the commitment of all the staff of the timber harvesting company, at every level of responsibility, to search for excellence in safety as one more entrepreneurial goal. This fact should be accompanied by the staff early training and the adequate motivation means. (Author) 12 refs.

    The aim of this work was to evaluate the efficiency of deciduous tooth cavity preparation by the Er:YAG laser in comparison with the conventional burr rotary instrument. Besides, we have used the laser fluorescence technique (DIAGNOdent equipment) for diagnosis and compared it to the usual tactile and visual examination as well as X-ray diagnosis. For this purpose, 20 chronic occlusal carious deciduous molar teeth from children with the ages between 5 to 10 years old were selected. Selection was ma de according to visual inspection, X-ray periapical image and measures of the DIAGNOdent. For treatment the teeth were divided in two groups, 10 to be treated by the Er:YAG laser and 10 with conventional burr. For enamel, the laser energy used was in the interval from 200 to 300 mJ; for the dentine the range was from 100 mJ to 200 mJ. In both cases, the laser frequency was in the range from 2 to 4 Hz. The results have shown that the laser treatment was more accepted by the children than the conventional burro Clinical evaluation of the cavity preparation indicates that the Er:YAG laser treatment is recommend. The DIAGNOdent evaluation method was very effective for diagnosis of carious tissue for initial detection. After successful removal of the carious tissue, confirmed by visual inspection, the DIAGNOdent evaluation method was only effective for the treatment with conventional burro For evaluation of the tooth after cavity preparation with the Er:YAG laser, the measurements oscillate covering the full range of the equipment. Therefore, the use of the DIAGNOdent equipment is indicated only for initial caries diagnosis. (author)

    Cardiovascular diseases account for the main causes of morbidity and mortality among the adult population. Despite the advances of preventive medicine, acute myocardial infarction continues to be frequent and the difficulty of the differential diagnosis is an additional cause of fatal events. Its diagnosis is based on the triad: typical chest pain, alterations in the electrocardiogram and elevation of serum cardiac enzymes. However, many patients evolve without the complete syndrome. Therefore the development of non-invasive assays for the early detection of damaged myocardium is of extreme importance. {sup 99m}Tc-glucarate is a radiopharmaceutical of great interest for application in Nuclear Medicine, because it is referred as a potential marker of necrotic tissues in the early phase of an acute coronary event. This presentation describes the optimization of preparation, lyophilization and labelling as well as quality control procedures of {sup 99m}Tc-glucarate, based on former studies published in the literature. Radiochemical purity was evaluated by the ascending paper chromatography technique. Labelling efficiency as a function respectively of time of reaction, volume and activity of {sup 99m}TcO4- was consistently higher than 97%. The lyophilized kit was stable during 12 months of storage. Biodistribution in healthy Swiss mice showed rapid blood clearance, renal excretion and low uptake by organs adjacent to the heart. Scintigraphic studies of injected Wistar rats confirmed the results of the biodistribution obtained by direct organ counting. Scintigraphies of infarcted female rats proved the sensitivity of the method. (author)

    Two sets of quantities are import in radiological protection: the protection and operational quantities. Both sets can be related to basic physical quantities such as kerma through conversion coefficients. For diagnostic x-ray beams the conversion coefficients and backscatter factors have not been determined yet, those parameters are need for calibrating dosimeters that will be used to determine the personal dose equivalent or the entrance skin dose. Conversion coefficients between air kerma and personal dose equivalent and backscatter factors were experimentally determined for the diagnostic x-ray qualities RQR and RQA recommended by the International Electrotechnical Commission (IEC). The air kerma in the phantom and the mean energy of the spectrum were measured for such purpose. Harshaw LiF-100H thermoluminescent dosemeters (TLD) were used for measurements after being calibrated against an 180 cm{sup 3} Radcal Corporation ionization chamber traceable to a reference laboratory. A 300 mm x 300 mm x 150 mm polymethylmethacrylate (PMMA) slab phantom was used for deep-dose measurements. Tl dosemeters were placed in the central axis of the x-ray beam at 5, 10, 15, 25 and 35 mm depth in the phantom upstream the beam direction Another required parameter for determining the conversion coefficients from was the mean energy of the x-ray spectrum. The spectroscopy of x-ray beams was done with a CdTe semiconductor detector that was calibrated with {sup 133} Ba, {sup 241} Am and {sup 57} Co radiation sources. Measurements of the x-ray spectra were carried out for all RQR and RQA IEC qualities. Corrections due to the detector intrinsic efficiency, total energy absorption, escape fraction of the characteristic x-rays, Compton effect and attenuation in the detector were done aiming an the accurate determination of the mean energy. Measured x-ray spectra were corrected with the stripping method by using these response functions. The typical combined standard uncertainties of conversion coefficients and backscatter factors were 12% and 6% respectively. (author)

    During an accident a technician's two hands were contaminated with hexaplutonium-239 nitrate. The contamination on the left hand alone, measured with an X-detector, was close on 60 {mu}c . The contamination was brought down to 15 {mu}c by a first decontamination carried out under a local anaesthetic; several contamination zones were localized by scanning. A surgical operation, done under an Esmach band with X and {alpha}-detectors, reduced the contamination from 15 to 5 {mu}c, the hands' functions being integrally preserved. A new zone of activity was localized by a second scan, and a second operation reduced internal contamination in the hand to 2 {mu}c. It has not been possible to localize this activity but it is kept under regular supervision. Parallel with the surgical decontamination, an internal decontamination with DTPA was undertaken. Blood, urine and faeces were sampled immediately after the accident and their activity was measured. Afterwards, urine samples were taken daily; blood and faecal samples were taken during each period of treatment. All the measurements indicate that DTPA is extremely effective in the case of internal contamination by Pu{sup 239}. It also appears that the percentage of blood plutonium eliminated by the kidney varies with time. The percentage increases, indicating that the plutonium is carried in the blood under different ionic or colloidal forms which are cleared in different degrees by the kidneys. It would accordingly appear that the activity in the urine does not faithfully reflect the internal contamination. (author) [French] Au cours d'un accident, les deux mains d'un technicien ont ete contaminees par du nitrate de plutonium-239 hexavalent. Pour la seule main gauche, la contamination, mesuree avec un detecteur de rayons X, etait voisine de 60 {mu}c. Une premiere decontamination, sous anesthesie locale, a permis de remener la contamination a 15 {mu}c . Grace a un , on a localise plusieurs zones de contamination. Une intervention chirurgical, faite sous bande d'Esmach avec l'aide dedetecteurs de rayons X et {alpha}, aramene la contamination de 15 a 5 {mu}c, tout en conservant l'integrite des fonctions de la main. Un deuxieme a permis de localiser une nouvelle zone d'activite, et une deuxieme intervention a abaisse la contamination interne de la main a 2 {mu}c. Il n'a pas ete possible de localiser cette activite, dont l'evolution est regulierement controlee. En parallele avec cette decontamination chirurgicale, une decontamination interne avec l'ADTP a ete entreprise. Des l'accident, les prelevements suivants ont ete faits: sang, urine, matieres fecales, et leur activite mesuree. Par la suite, les prelevements urinaires ont ete quotidiens. Les prelevements sanguins et fecaux ont ete faits a chaque periode de traitement. De toutes les mesures, il ressort que l'efficacite de l'ADTP est tres grande dans les contaminations internes avec {sup 239}Pu. Mais il apparait aussi que le pourcentage de plutonium sanguin elimine par le rein varie en fonction du temps. Ce pourcentage croit, ce qui montre que le plutonium est vehicule dans le sang sous diverses formes ioniques ou colloidales que le rein elimine a des taux differents. Il ne semble donc pas que l'activite urinaire soit un reflet fidele de la contamination interne. (author) [Spanish] A raiz de un accidente, un tecnico del centro de Fontenay-aux-Roses se contamino las manos con nitrato de hexaplutonio-239. La contaminacion de la mano izquierda, medida con un detector de rayos X, era del orden de 60 {mu}c, Una primera descontaminacion, efectuada con anestesia local, redujo el valor numerico a 15 {mu}c; por exploracion, se localizaron varias zonas de contaminacion. Se intervino quirurgicamente bajo una banda de Esmach con detectores X y {alpha} y se disminuyo la contaminacion de 15 a 5 {mu}c, conservando integras las functiones de las manos. Por una segunda exploracion se localizo una nueva zona de actividad y se volvio a intervenir reduciendo la contaminacion interna de la mano hasta 2 {mu}c. Si bien esta actividad no se pudo localizar, se somete a vigilancia periodica. Simultaneamente con la descontaminacion quirurgica, se procedio a una descontaminacion interna con DTPA. Inmediatamente despues del accidente, se tomaron muestras de sangre, orina y heces y se midieron sus actividades. Despues se recogieron diariamente muestras de orina; durante cada periodo de tratamiento, se tomaron asimismo muestras de sangre y de heces. Todas las mediciones indican que el DTPA es sumamente eficaz en-el caso de contaminacion interna por {sup 239}Pu. Tambien parece que el porcentaje de plutonio de la sangre que se elimina por el riflon varia con el tiempo. Este porcentaje aumenta, lo que indica que el plutonio es transportado por la sangre en diversas formas ionicas o coloidales que los rinones filtran en grado variable. Existen, pues, razones para suponer que la actividad de la orina no refleje fielmente el grado de contaminacion interna.

    The aim of this study was to evaluate the methods for establishing dental caries diagnosis that make use of Laser light as source of illumination, establishing the 'state of the art'. Experimental observation of the differences among fluorescence of sound, demineralized and carious enamel by visible luminescent spectroscopy was also done. Six human teeth, extracted for clinical reasons were studied, and the results showed that the spectrum of carious enamel is different from the sound and demineralized ones. The differences are more evident relative to sond enamel and carious enamel, the same occurring between demineralized and carious enamel. The review of the literature aimed to make comparative considerations between QLF, LF and DELF; their effectiveness relative to traditional methods such as visual, visual with probe, radiography. It was verified that DELF was more sensitive, but could not discriminate between different degrees of mineral loss. QLF, compared to DIAGNOdent has the same sensitivity, but it is better for scientific purposes. The experimental part of the present study used on argon ion Laser to illuminated the teeth and signs of emission of fluorescence were captured by a PMT and then analyzed by a computer system with EG and G software. The results showed that the spectrum of carious enamel is different from the sound and demineralized. The differences are more evident in relation to sound and carious enamel, the same occurs between demineralized and carious enamel. (author)

    The more used method in the diagnosis of secondary bone lesions to become cancerous it is by means of having derived of phosphates like it is the {sup 99m}Tc- MDP. The reason of acquiring searching with the radiopharmaceutical {sup 99m}Tc- DMSA V is with the purpose to find other bone lesions that are not visualized with the gammagraphy with diphosphonate and therefore to increase the specificity of the study.

    Nosocomial infections have become more important to the health system by the high costs of these, but are little data available about them in recent years. The clinical utility of the determination of serum galactomannan (GMS) in patients with high risk of contracting the infection by Aspergillus spp, was assessed, between January 2009 and December 2012 at the Hospital San Juan de Dios. Several existing studies in the scientific literature have already evaluated the clinical usefulness, specific data have been inexistent for Costa Rica or for Central America and the Caribbean; so it is important to have known whether the conduct of the test has been similar to the other populations or have specific variations [Spanish] Las enfermedades nosocomiales han cobrado mayor importancia para el sistema de salud por el gasto elevado que han representado, pero son pocos los datos disponibles respecto a ellas en los ultimos anos.

    The aim of this study was to compare the ability of 67-Gallium citrate (67Ga), 99m-Tc labelled leucocytes (99mTc-WBC) and 111-In-labelled immunoglobulin G (111In-IgG) scintigraphy in bone and joint infections diagnosis. Fifty-six patients were studied. For all patients a bone scan using 99mTc-MDP was indicated. The patients were randomized allocated for 67Ga (Group 1 - 22 patients) or simultaneous administration 99mTc-labelled leucocytes and 111In-IgG.(Group 2 - 34 patients) study. For the groups 1 and 2 were confirmed respectively 12/26 y 11/34 septic lesions. The 67Ga scintigraphy showed 6 true-positive, 9 true-negative, 5 false-positive and 6 false-negative. With 99mTc-WBC, the respective values were 8, 18, 5 and 3. With 111In-IgG, the figures were 7, 17, 6 and 4, respectively. The sensitivity, specificity and accuracy were 50%, 64,3% and 57,7% respectively for the 67Ga, 72,7%, 78,2% and 76,4% respectively for 99mTc-WBC and 63,6%, 73,9% and 70,6% respectively for 111In-IgG. In this study, the labelled leucocytes scintigraphy showed more accurate than 67Ga and 111In-IgG scans for the diagnosis of bone and joint infections. However, the obtained results were less reliable for the diagnosis of occult sepsis in the patients with joint prosthesis (Au)

    Purpose: To evaluate the role of PET-CT with FDG-{sup 18}F in the detection of recurrence and/or metastasis of differentiated thyroid carcinoma (DTC) in patients with elevated levels of thyroglobulin (TG) and negative whole body scan (WBS). Patients and method: PET-CT findings of 25 patients were compared to histopathology evaluation and conventional imaging (CI). Results: PET-CT scan was positive in 16 patients finding 14 true-positive and 2 false-positive cases (positive predictive value 87.5%). Nine patients had negative PET-CT; two had decrease of TG to undetectable levels. One patient had residual disease detected by post-therapeutic WBS. Six patients had no evidence of tumor during follow-up (mean time 16 months). PET-CT was concordant with CI in 52%, partially concordant in 12% and discordant in 36% (6 false-negatives and 3 false-positive of CI). We observed a tendency of increasing proportion of positive PET-CT with increasing TG. Conclusion: PET-CT scan with FDG-{sup 18}F is useful in the detection of recurrence and/or metastases of DTC with high TG levels but negative WBS. It presents elevated positive predictive value and is superior to CI being more effective as higher the serum TG levels. (author)

The sample was composed of 24 athletes, aged 16-23 yr, 12 males (19.7 ± 2.4 yr and 12 females (19.2 ± 1.8 yr. The following procedure was applied to diagnose the nutritional status: analysis of the adequability of energy and macronutrient intake - carbohydrates (CHO, lipids (LIP and proteins (PRO -, through the methods 24-hr diet records and the Food Consumption Frequency Questionnaire, besides anthropometrical profile characterization. The results obtained from the dietary evaluation showed that the energy distribution among the macronutrients was adequate, 54 ± 6.8% (CHO; 28,5 ± 5.9% (LIP; and 14.5 ± 3.4% (PRO for the male team, and 56.3 ± 4.7% (CHO; 28.6 ± 4.6% (LIP; and 13.7 ± 2.4% (PRO for the female team. However, regarding total energy intake, 83% of the athletes presented energy intake below the recommended values, considering the high level of physical activity, resulting in daily caloric deficiency. Body fat percentage of the male athletes (3.6 ± 0.7% indicated that all of them were below the reference standard, while 58% of the female athletes had excess fat (17.9 ± 5.8%. It was concluded that although the athletes showed an adequate caloric distribution of macronutrients, it was still not sufficient to meet the energy requirements of their modality, thus these athletes should seek nutritional orientation.

    Gastrin-rea leasing peptide receptors (GRP-r) are over expressed in breast and prostate cancer cells. Bombesin (Bn) binds specifically and strongly to GRP-r and this is the base for to label the Bn with radionuclides by gamma rays. Tat (49-57) is a peptide that across the cell membrane easily so that, when it is conjugated to different proteins, it can works as a Trojan horse, facilitating the drug internalization to the cells. The radiopharmaceutical {sup 99m}Tc-N{sub 2}S{sub 2}-Tat(49-57)-Lys{sup 3}-Bn was prepared for diagnosis and therapy at early stage of breast cancer. The objective of this study was to determine the role of Tat in the internalization kinetics of radiopharmaceuticals measured by DNA damage induced by means of comet assay. Human lymphocytes were treated with the following protocols: a) Tat-Bn, b) {sup 99m}Tc-Bn, or c) {sup 99m}Tc-N{sub 2}S{sub 2}-Tat(49-57)-Lys{sup 3}-Bn, also an untreated group was conformed. The internalization was evaluated at 0, 5, 10, 15, 30 and 60 min after exposure with three repetitions each one, and for radiopharmaceuticals with 2.9, 6.6, 9.0 and 14.8 MBq activities. DNA damage was scored in 100 cells per time and treatment, as tail length and tail moment. A Kruskal-Wallis variance analysis with p{<=} 0.05 was applied for comparison between treatments. The results showed that the damage caused by {sup 99m}Tc-N{sub 2}S{sub 2}-Tat(49-57)-Lys{sup 3}-Bn is significantly higher than that caused by {sup 99m}Tc-Bn and Tat-Bn, showing that Tat favors the internalization of the radiopharmaceutical.

    This paper analyzes the work done in Cuba over the last years in the field of photovoltaic, from its R and D and Industrial capacities to the Rural Electrification Program. Based on this work a Development Program for the PV industry is proposed, which is defected towards the integration of all necessary factors that will ensure a sustainable Rural Electrification Program. This program is divided in 5 main stages: 1. Import of solar cells and other elements for the assembly in Cuba of modules and diverse system components (1995-2005). 2. Production of solar cells from imported wafers (1997-2005). 3. Production of monocrystalline silicon wafers from imported plycrystalline silicon (1998-2005). 4. Production of polycrystalline silicon from Cuban silica sand (2000-2005). 5. Development and introduction of new technologies for the production of solar cells (2000-2005). The combination of the PV Development program and the Rural Electrification program will guarantee the supply of electricity to 100% of the Cuban population, and at same time accelerate the technological, industrial and research infrastructure on which a large scale national PV industry would be supported. The implementation of such a program would also make cost on the National Electrical Grid (NEG), avoiding the need for new generation facilities based on fossil fuels.

    Thirty-one thermal and nonthermal water samples were collected in Panama by the Instituto de Recursos Hidraulicos y Electrificacion and analyzed by the Earth and Space Sciences Division at Los Alamos National Laboratory to evaluate the geothermal potential of four different areas. Chemical and isotopic analyses were performed on each sample. Because samples from several areas were submitted, the chemistry of the samples is varied, with total dissolved solids of thermal fluids ranging from 900 to nearly 10,000 mg/{ell}. All water samples studied are meteoric in origin, and none of the thermal waters exhibit an {sup 18}O enrichment, which is characteristic of high-temperature isotopic, exchange between water and rock. At all four areas, calculated geothermometer temperatures within a reservoir of less than 160{degrees}C. 4 refs., 4 figs., 6 tabs.

    Since 1988 the Institute of Solar Energy of the Universidad Politecnica de Madrid is carrying out a pv rural electrification programme at the Bolivian high plateau. This programme has been focused in three aspects: the domestic electrification, users participation and transfer technology. At present, there are about 1,500 electrified dwellings distributed in the Bolivian high plateau. We have got deep knowledge about life style and organization of the aymara Indians who are the inhabitants of the working zone. We think that this knowledge can be very useful for a large scale introduction of PV solar energy in this region. Finally, we present a new way to transfer PV technology to developing countries. Thanks to this programme a group of aymara Indians is able to manufacture charge regulators and electronic ballast to use in the PV installations of the programme.

    This work present the development of a reprocessing method to reduce the information of the original data and to maintain the essential information of the data that enter the reduction process. The obtaining of these data is performed with the aid of the ICM ++ (ICMsystems), from which vectors or n-uplos of elements are obtained. This investigation allowed to analyze an evaluation of the paradigms of artificial neural networks, with the intention of detecting which of these paradigms would evolve better with the problem of fault diagnosis in electric generators. From this a prototype system was developed called diagnosis of faults in electrical generators, which automatically will recognize faults in electrical generators by means of the interpretation of the recording of partial discharges.

    Full Text Available El presente trabajo tiene como objetivo analizar indicadores de vulnerabilidad ante casos de inundación en el barrio Intendente Alfredo Mario Etchepare de la ciudad Trelew, Argentina. Se parte de la comparación entre dos diagnósticos: el diagnostico tecnico-cientifico, realizado a partir de la consulta bibliográfica, la búsqueda de documentos y la aplicación de entrevistas a técnicos y actores clave del barrio; y el diagnostico analítico de la percepción de los habitantes del barrio, realizado luego de examinar la información obtenida mediante un cuestionario semiestructurado. Debido al reconocimiento de diferencias entre los diagnósticos tecnico-cientifico y de percepción social, se plantea la importancia de establecer una fase preanalitica, indispensable para la selección y puesta en practica de cualquier estrategia de gestión de riesgos.

    Full Text Available El resultado de los casos notificados de Sida en las mujeres mostró aporte en la prevención de la transmisión vertical y en la asistencia materno-infantil para la reducción de la morbilidad y mortalidad. Esa investigación tuvo como objetivo intuir los significados de estar embarazada y tener VIH/SIDA. La entrevista se desarrolló con siete mujeres, entre marzo y abril de 2009. La misma se realizó en un hospital universitario en Santa María/RS/Brasil. Investigación cualitativa de planteo fenomenológico por el método de análisis comprensivo de Martín Heidegger. El análisis comprensivo dejó ver la dificultad al descubrir el diagnostico y el miedo de transmitir el virus a los hijos, de no poder cuidarlos y de morir. Describen experiencias de otras gestaciones y de embarazo no planeado. Conocen el recelo, por eso la familia no sabía del diagnostico. Se concluye que es forzoso reflexionar sobre las prácticas de salud, de modo que se lleve a cabo en el cotidiano asistencial una percepción empática buscando comprender lo ya vivido y las necesidades de las mujeres y familias.

    Full Text Available La hepatitis B es una enfermedad inflamatoria del tejido hepático causada por la infección crónica del virus de la hepatitis B (VHB. Su diagnostico se basa en la detección de anticuerpos y antígenos contra dos de sus principales proteínas inmunogenicas, el antígeno de superficie (HBsAg y el del core (HBcAg. Existen otros dos componentes de la envoltura altamente inmunogenicos el preS1/2, sin embargo su papel en la evaluación de la respuesta serológica aún no ha sido evaluado. Es por ello que en este trabajo se propone expresar y purificar el preS1/2 usando a la Escherichia coli como sistema de expresión por ser el menos costoso a fin de obtener una proteína con propiedades antigénicas adecuadas para su utilización en el diagnostico serológico y evaluación de la respuesta inmune. El preS1/2 previamente clonado en el vector pET3d-preS1/2 se utilizó para transformar a la cepa de Escherichia coli (HMS174 y después de inducir la síntesis proteica mediante el uso de IPTG, se purifico mediante columna de afinidad al níquel, posteriormente analizadas en gel de electroforesis poliacrilamida, para seleccionar las fracciones de preS1/2. Después de dializarlas y liofilizarlas se logró obtener 5,4 mg/ml de la proteína pura, confirmado mediante la realización del western blott con un anticuerpo monoclonal específico. Estos resultados indican que este método es fácil, poco costoso y rápido para obtener una proteína pura con potencial uso en el diagnostico serológico de la infección por VHB.

    Discacciatti, Adrian; Cruzate, Juan A.; Bomben, Ana M.; Carelli, Jorge; Namias, Mario

    2008-01-01

    The radiological assessment of a Positron Emission Tomography (PET) facility consists of the evaluation of the annual effective dose to workers exposed occupationally and to members of the public. This evaluation takes into account the radionuclide involved, the characteristics of the facility, the working procedure and the expected number of patients per year. This paper details the methodology used by the Nuclear Regulatory Authority (in Spanish ARN) to independently assess the design of PET facilities considering only radioprotection aspects. The results of the evaluation are compared with the design requirements established in the ARN regulations to determine whether or not, the facility complies with those requirements, both for workers and for members of the public. As an example of the above mentioned methodology, this paper presents the assessment of a PET facility located in Buenos Aires called Fundacion Centro Diagnostico Nuclear (FCDN). (author)

    Since the early nineties Brazil has initiated a program of reforms in its electric sector which includes utility privatization, de-verticalization. The main objectives were to promote a market-oriented energy industry attractive to private investments. This has led to the loss of sponsorship for the public-interest programs formerly undertaken by the state utilities. In particular, of significant concern are the programs for promotion of energy efficiency, renewable energy technologies, rural electrification and environmental protection. In the midst of the privatization effort, the National Agency for Electrical Energy ANEEL was created (end of 1997). One of the tasks of the regulatory agency is to provide funds and incentives to energy conservation. In this paper we review the role of ANEEL in promoting energy efficiency investments in the context of a market-oriented sector, its limitations and prospects. [Spanish] Desde principios de los anos noventa Brasil ha iniciado un programa de reformas en su sector electrico que incluye la privatizacion del servicio electrico y la desverticalizacion. Los objetivos principales eran promover una industria de la energia orientada comercialmente de la energia electrica, atractiva a las inversiones privadas. Esto ha conducido a la perdida de patrocinio de los programas de interes publico emprendidos antes por las empresas electricas del estado. En particular, de preocupacion significativa estan los programas para la promocion del rendimiento energetico, de las tecnologias de la energia renovable, de la Electrificacion rural y de la proteccion del medio ambiente. En medio del esfuerzo de la privatizacion, la agencia nacional para la energia electrica ANEEL fue creada (finales de 1997). Una de las tareas de la agencia reguladora es proporcionar fondos e incentivos a la conservacion de energia. En este trabajo repasamos el papel de ANEEL en promover inversiones del rendimiento energetico en el contexto de un sector orientado

    Fault detection and diagnosis on transmission systems is an interesting area of investigation to Artificial Intelligence (AI) based systems. Neurocomputing is one of fastest growing areas of research in the fields of AI and pattern recognition. This work explores the possible suitability of pattern recognition approach of neural networks for fault detection and classification on power systems. The conventional detection techniques in modern relays are based in digital processing of signals and it need some time (around 1 cycle) to send a tripping signal, also they are likely to make incorrect decisions if the signals are noisy. It's desirable to develop a fast, accurate and robust approach that perform accurately for changing system conditions (like load variations and fault resistance). The aim of this work is to develop a novel technique based on Artificial Neural Networks (ANN), which explores the suitability of a pattern classification approach for fault detection and diagnosis. The suggested approach is based in the fact that when a fault occurs, a change in the system impedance take place and, as a consequence changes in amplitude and phase of line voltage and current signals take place. The ANN-based fault discriminator is trained to detect this changes as indicators of the instant of fault inception. This detector uses instantaneous values of these signals to make decisions. Suitability of using neural network as pattern classifiers for transmission systems fault diagnosis is described in detail a neural network design and simulation environment for real-time is presented. Results showing the performance of this approach are presented and indicate that it is fast, secure and exact enough, and it can be used in high speed fault detection and classification schemes.

    Among the different renewable energy technologies, wind provides better possibilities in regions in which this resource is available. The advantages of wind, as well as solar energy technologies are less or none fuel costs and less environmental impacts. According to the current available technology development, the use of hybrid systems of photovoltaic and wind energy presents large opportunities to cover the energy needs of isolated areas, specially in facilities that don't have connection to the national transmission grid. This study presents the different environmental impacts that hybrid systems have (incorporing the landscape impacts as well as socioeconomical impacts) for the electricity generation in Cuba. We conclude that these systems allow an important power generation in Cuba, and that they have neglected impacts to the environment. The use hybrid systems in Cuba are particularly important in ecotourism facilities and other small industries. [Spanish] Dentro de las posibilidades energeticas y medioambientales de los distintos tipos de energias renovables; la eolica por su caracter limpio e inagotable, permite un gran desarrollo en aquellas areas que cuentan con el potencial necesario para su aplicacion. De forma similar la energia solar presenta ventajas importantes, ambos son recursos gratuitos, no contaminantes y disponibles en muchas localidades. Segun las tecnologias actualmente disponibles, la utilizacion de sistemas hibridos de energia solar fotovoltaica y eolica presenta mayor interes hoy en dia para cubrir consumos aislados, en instalaciones alejadas de la red nacional de electrificacion. Este trabajo plantea un estudio, de la afectacion que sobre el medio ambiente, tanto en el aspecto visual como socioeconomico, tienen las fuentes energeticas renovables, y especificamente los sistemas hibridos eolico- fotovoltaicos para la generacion de electricidad en Cuba, a partir de conocer los recursos eolico y solar disponible en el lugar del

    The basic reason to use alternative systems for electricity generation, in most cases, is the lack of electricity services, such as isolated rural communities which are located far away from the electric distribution line, and the cost of its extension is too expensive, while decentralized power systems can be an economic and appropriate solution to providing these services. Up to now there are several technological options for rural electrification using PV modules, wind plants, water-power plants, anaerobic digesters, or a combination of some of them, according to the availability of energetic resources. The applications include centralized or decentralized systems, autonomous or hybrid systems, isolated or interconnected to the electric line, etc. A particular hybrid system design can be done considering two general aspects, first it is necessary to know the electric consumption that will be supplied, taking into account present and future necessities and how local energetic resources are present in a selected site. Finally, also it is necessary to carry out an economic analysis to determine the cost of kilowatt-hour generated using local energetic resources and compare it with the cost of electricity produced by conventional power systems.

    Photovoltaic solar generators combined with diesel engines, in some cases additionally with wind energy converters, and battery energy storage are powering isolated mountain lodges, information centers in nature parks, isolated farms or dwellings all over Europe. A total of 300,000 buildings in Europe are estimated to be not connected to the public grid. This represents a major market potential for photovoltaic, as often photovoltaic power generation is less expensive than a connection to the electric utility. The Fraunhofer Institute for Solar Energy Systems ISE has planned, realized and monitored about 30 hybrid remote energy supply systems with PV generators typically around 5 kW for loads typically around 20 kWh per day. More than one hundred years of operational experience accumulated so far, are a sound foundation on which to draw an interim balance over problems solved and technical questions still under development. Room for further technical development is seen in the domain of system reliability and the reduction of operating costs as well as in the optimization of the utilization of the electric energy produced by the PV generator.

    In 1988, the Instituto Geofisico (IG) began a permanent surveillance of Ecuadorian volcanoes, and due to activity on Guagua Pichincha, SP seismic stations and EDM control lines were then installed. Later, with the UNDRO and OAS projects, telemetered seismic monitoring was expanded to Tungurahua, Cotopaxi, Cuicocha, Chimborazo, Antisana, Cayambe, Cerro Negro, and Quilotoa volcanoes. In 1992 an agreement with the Instituto Ecuatoriano de Electrificacion strengthened the monitoring of Tungurahua and Cotopaxi volcanoes with real-time SP seismic networks and EDM lines. Thus, background activity levels became established, which was helpful because of the onset of the 1999 eruptive activity at Tungurahua and Guagua Pichincha. These eruptions had a notable impact on Baños and Quito. Unrest at Cotopaxi volcano was detected in 2001-2002, but waned. In 2002 Reventador began its eruptive period which continues to the present and is closely monitored by the IG. In 2006 permanent seismic BB stations and infrasound sensors were installed at Tungurahua and Cotopaxi under a cooperative program supported by JICA, which allowed us to follow Tungurahua's climatic eruptions of 2006 and subsequent eruptions up to the present. Programs supported by the Ecuadorian Secretaria Nacional de Ciencia y Tecnologia and the Secretaria Nacional de Planificacion resulted in further expansion of the IG's monitoring infrastructure. Thermal and video imagery, SO2 emission monitoring, geochemical analyses, continuous GPS and tiltmeters, and micro-barometric surveillance have been incorporated. Sangay, Soche, Ninahuilca, Pululahua, and Fernandina, Cerro Azul, Sierra Negra, and Alcedo in the Galapagos Islands are now monitored in real-time. During this time, international cooperation with universities (Blaise Pascal & Nice-France, U. North Carolina, New Mexico Tech, Uppsala-Sweden, Nagoya, etc.), and research centers (USGS & UNAVCO-USA, IRD-France, NIED-Japan, SGC-Colombia, VAAC, MIROVA) has introduced

    To the interior of the Generation of Electrical Equipment (GEE) of the Instituto de Investigaciones Electricas, one of the main activities is the diagnosis of the electrical equipment in service. It is well known that the power equipment represents a strong investment that requires the guarantee that it has been manufactured, installed and operated satisfactorily. The life expectancy of these devices is of thirty years, however, many of them already have surpassed that expectation. The rehabilitation or substitution of the equipment implies new investments that are needed for an evaluation of the real condition of the equipment to carry out such rehabilitation. One of the tools necessary to carry out the diagnosis, is a movable laboratory that facilitates all the necessary tools to perform a meticulous analysis that would allow, the client, to make high cost decisions. The application of the movable laboratory is advisable from the inauguration of the equipment. The electrical mechanisms are factory tested in accordance with standardized protocols; it guarantees the fulfillment of the necessary requirements for a correct operation. Nevertheless, when taking them to the assembly site, these are subjected to a series of processes and mechanical stresses that could alter the equipment conditions and its integrity.

    This investigation analyses the computerized axial tomography (CAT) of thorax with protocol of bronchiectasis. It was carried out in the Servicio de Radiologia e Imagenes Medicas of the Hospital Calderon Guardia, Costa Rica. The bronchiectasis is the abnormal permanent expansion of the bronchial tuber and is important to diagnose it because the patient can suffer of pulmonary infections, these can be accompanied by bronchial blood flow and hemoptysis. When they are disseminated can be associated with significant obstruction of the aerial tract. When they are gotten into focus can be confused with neoplasia and other diseases. From the bronchiectasis diagnosis it is used methods of image such as x-ray of thorax, bronchography and computerized axial tomography (CAT) of thorax, usually the diagnosis is confirmed by means of a computerized axial tomography (CAT); which is the image of election to establish the presence and extension of the bronchiectasis. In addition, this study analyzes the radiological clinical relation in the patients which were performed the computerized axial tomography (CAT) of thorax with protocol of bronchiectasis and it identifies the most suitable radiological technique to obtain a satisfactory result in the computerized axial tomography with protocol of bronchiectasis.

El diagnostico se suele realizar como un hallazgo incidental al hacer una radiografia de torax a un nino por infecciones respiratorias repetidas, o en la edad adulta en una exploracion radiologica de rutina, en una persona por lo demas asintomatica. Es importante diferenciar este sindrome de otras causas de hiperclaridad pulmonar unilateral en las radiografias de torax convencionales. Pocos casos del Sindrome Swyer-James han sido reportados en ninos. Se presenta el caso clinico de un paciente quien tuvo una bronconeomonia parainfluenza 3 al mes y 18 dias de edad. El diagnostico diferencial de este sindrome se debe hacer con otras entidades toracicas que disminuyen la densidad radiologica pulmonar unilateral.

    Often, the rotary equipment faults appear as an abnormal vibration or a change in the characteristic vibration pattern of each machine. From here the importance of counting on tools that allow to acquire and to analyze the vibration signals of the equipment while it is in operation. The Gerencia de Turbomaquinaria has worked in this field since the end of the Seventies, developing diagnosis systems based on personal computers that allow the monitoring of the dynamic behavior of the rotary equipment. The main system of this type that the Instituto de Investigaciones Electricas (IIE), nowadays offers, is the Computerized System for Dynamic Analysis, also known by its abbreviation in Spanish as: SICAD II. This was designed under the requirements of the Comision Federal de Electricidad (CFE) to collect, measure and analyze vibration data of rotary equipment. It is also used in the balance, fault diagnosis and the solution of problems in rotary equipment. The system SICAD II is portable and versatile system with which vibrations are acquired, measured and analyzed by means of the presentation of the data in graphical formats of different type and application.

    Full Text Available INTRODUCCION: Listeria monocytogenes tiene una especial predilección por infectar el sistema nervioso central y sus cubiertas meningeas. Afecta a pacientes que se encuentran en edades extremas de la vida, pacientes con deficiencia en su inmunidad celular y adultos sanos. La forma mas común de manifestarse es la meningitis aguda, aunque puede expresarse como cerebritis, encefalitis de tronco (romboencefalitis, y excepcionalmente mielitis. CASUISTICA: Se presentan y comentan seis casos clinicos de neurolisteriosis, cinco en adultos sanos, con sus hallazgos imagenológicos y licuorales. RESULTADOS: Tres de los pacientes se presentaron como meningitis aguda, uno como meningoencefalitis, otro como cerebritis y el restante como romboencefalitis. Se destaca el carácter turbio o ligeramente turbio del líquido cefalo-raquideo (LCR, la glucorraquia normal detectada en tres de los casos y el diagnostico realizado en cinco de los casos por cultivo del LCR. Se comenta la resonancia magnética singular del caso de la romboencefalitis con microabscesos en tronco. Todos los pacientes tuvieron evolución satisfactoria con tratamiento antibiotico. CONCLUSIÓN: La neurolisteriosis debe ser un diagnostico a tener en cuenta no solo en pacientes inmunocomprometidos o en edades extremas de la vida. Debe también tenerse en cuenta en pacientes adultos jóvenes sanos procedentes de regiones donde las condiciones sanitarias son precarias y no existe un adecuado control en la elaboración de alimentos.INTROCTION: Listeria monocytogenes shows a special attraction to infect the central nervous system and its meningeals coats.

    Full Text Available This article presents the nature, bases, and coherence requirements of a plan, in order to specify the methodological criteria of its internal critique of the agricultural chapter. The examination of its diagnosis leads to a different diagnosis, which is inferred by the objective of "integrating the rural sector": the persistence of the agrarian problem, expressed in a bimodal structure, polarized into 'the economic' and 'the social'. The plan's objective reveals a long-term vision: to
    contribute to the solution of the agrarian problem. Thus, the policies differentiate between the advanced entrepreneurial and peasant sectors, for which it designs different strategies which assign different roles for the state: to facilitate socioeconomic processes for the former, and to promote rural development for the latter. The article shows that the Plan maintains internal coherence, and illustrates its limitations
    due to the institutional environment, which is manifested in its
    design and in the possibilities for its execution. It concludes that the most important policies are the weakest, and that rural developmerlt is not only a problem of social design, but above all of the mentality and commitment of society on all levels.Este articulo expone la naturaleza, fundamentos y requerimientos de coherencia de un plan para precisar los criterios metodologicos de su critica interna al capitulo agropecuario.

    Full Text Available En pacientes con enfermedad hepática aguda o crónica la encefalopatía hepática es una complicación progresiva y reversible en su mayoría de veces, que puede reducir la sobrevida y la calidad de vida de quienes la presenten. Dentro de su patogénesis existen diferentes hipótesis entre las cuales la más aceptada ha sido la de la neurotoxicidad por amonio, que incluso podría explicar las otras hipótesis planteadas, como la del edema de los astrocitos, la toxicidad por manganeso, entre otras. La clasificación actual de la encefalopatía hepática se propuso en el congreso mundial de Gastroenterología en 1998 y se basa en la naturaleza de la disfunción hepática, duración y características de las manifestaciones neurológicas. Para su diagnostico se requiere de un buen reconocimiento clínico puesto que es principalmente de exclusión; sin embargo actualmente se cuenta con los criterios de West Haven para clasificar la severidad de su presentación. En este síndrome el tratamiento comprende diferentes elementos –como la dieta proteica, disacáridos no absorbibles y terapia antibiótica, que tienen como finalidad la resolución de las manifestaciones y mejorar la calidad de vida de los pacientes, aunque sin dejar de lado que tratar los factores precipitantes son la principal medida terapéutica para la encefalopatía hepática. El objetivo de este artículo es revisar los últimos conceptos de la encefalopatía hepática; con especial énfasis en su patogénesis, clasificación, diagnostico y tratamiento.

    The radiopharmaceutical administration with diagnostic or therapeutic purpose during pregnancy implies a prenatal radiation dose. The dose assessment and the evaluation of the radiological risks become relevant due to the great radiosensitivity of the fetal tissues in development. This paper is a revision of the available data for estimating fetal doses in the cases of the more frequently used radiopharmaceuticals in nuclear medicine, taking into account recent investigation in placental crossover. The more frequent diagnostic and therapeutic procedures were analyzed according to the radiation doses implied. (author) 8 refs. [Espanol] La administracion de radiofarmacos con fines diagnosticos o terapeuticos durante el embarazo, resulta en una dosis absorbida en el feto. La evaluacion de esta dosis y la consiguiente estimacion del riesgo radiologico asociado, adquiere relevancia dada la mayor radiosensibilidad de los tejidos fetales con respecto a la de los adultos. El proposito de este trabajo es hacer una revision de los lineamientos existentes sobre las hipotesis a considerar en el calculo de dosis al feto para los radiofarmacos de uso mas frecuente, incorporando las investigaciones recientes que aportan informacion sobre la transferencia placentaria, teniendo en cuenta la edad gestacional. Se analizan las practicas diagnosticas y terapeuticas mas frecuentes comparando las dosis que implican en el feto con los limites internacionalmente aceptados. Se pretende asi disponer de las herramientas necesarias para responder a las consultas sobre los riesgo radiologicos debidos a la administracion de radiofarmacos a embarazadas. (autor)

Se trata de un estudio cualitativo, realizado en municipios de tres regiones de salud del Estado de Paraná, empleando la recolección de datos de treinta y dos familias. Los datos fueronanalizados por medio de indicadores. Los resultados apuntan carencias en los servicios de la red de salud mental en relación a los cuidados a las personas con trastorno mental y sus familiares en lo que concierne la necesidad de: adaptación tras el diagnostico de la patología; orientación familiar; adhesión al tratamiento; ingreso; auxilio financiero; asistencia para transporte; reinserción en la sociedad; inclusión en los servicios extra hospitalarios tras el ingreso y el vínculo entre el profesional y la persona asistida. Por lo tanto llegamos a la conclusión de que estas necesidades necesitan ser exploradas por los profesionales de la red en salud mental para la posibilidad y la concretización de una asistencia no institucionalizada, integral y resolutiva a la persona con trastorno mental y a su familia.

    Full Text Available La amenorrea es un criterio para el diagnostico de la anorexia nerviosa (AN según el DSM-IV-TR. Sin embargo, al comparar grupos de pacientes que cumplen todos los criterios de este manual para la AN con grupos de mujeres que los presentan todos salvo la amenorrea, algunos estudios no han encontrado diferencias significativas en la psicopatología típicamente asociadas con la AN. El propósito de nuestro estudio ha sido comparar variables demográficas, antropométricas, psicológicas y psicopatológicas, en ambos grupos. No se observaron diferencias estadísticamente significativas entre ambos grupos en las variables evaluadas, pero el grupo con amenorrea tenía un índice de masa corporal significativamente más bajo. Nuestros datos apoyan la hipótesis de que la amenorrea podría no ser un criterio diagnóstico útil para la AN.

    It retrospectively reviewed the diagnostic imaging findings (radiography, CT and US) of the cases of necrotizing fasciitis of soft tissues looking for signs that could be useful for early and accurate diagnosis. 130 patients with progressive necrotizing soft tissue infections were examined from May 1991 to February 1998. In 32 of them (22-84 years old) the retrospective pathologic diagnosis was necrotizing fasciitis. Involved sites were the limbs (26/32), the cervical region (5/32) and the perineal region (1/32). Nineteen patients were submitted to conventional radiography, also for soft tissue studies. US was performed in an emergency setting in all the 32 cases, by a selected group of US operators particularly skilled in this kind of soft tissue condition. Contrast enhanced CT was performed in 9 cases. B-mode and Doppler US yielded useful and reliable information for prompt and correct diagnosis. Particularly these techniques showed changes as shown at US and histologic findings, but US missed changes in subcutaneous soft tissue and muscle in 11 cases (3/32 and 8/32, respectively) with subsequent histologic confirmation. Contrast enhanced CT better defined the extent of disease and possible complications, especially in sites that are difficult to study with US. Early diagnosis and proper treatment are the key issues affecting the chances of recovery for patients with necrotizing fasciitis. The clinical suspicion of this condition calls for prompt intervention with effective diagnostic protocols. B-mode, and sometimes color Doppler, US and contrast enhanced CT, together with appropriate laboratory tests, can provide useful information for precise diagnosis and proper treatment.

O acometimento do sistema nervoso central (SNC pelo Mycobacterium tuberculosis é uma das formas da doença mais temidas na infância, devido à morbi-mortalidade alta que costuma causar. Este estudo teve como objetivo descrever aspectos epidemiológicos, clínicos e laboratoriais de 52 crianças com tuberculose do SNC em um hospital pediátrico terciário. A maioria dos pacientes apresentou idade baixa, estado nutricional precário, contato prévio com doentes, vacinação ausente ou tardia, comprometimento neurológico avançado, alterações quimiocitológicas de líquor compatíveis, assim como os achados de exames de imagem. A recuperação do agente no líquor e outros líquidos corpóreos por pesquisa direta ou cultura ocorreu em 40% dos pacientes. Apesar do perfil clínico-epidemiológico-laboratorial sugestivo e da viabilidade de acesso do paciente a serviço médico, na maioria dos casos o diagnostico foi tardio.

    Full Text Available El artículo se centra en la descripción de las intervenciones que se pueden realizar desde los Servicios de Prevención de Riesgos Laborales (SPRL y de Salud Mental ante los trastornos de salud mental y el abuso de sustancias en los trabajadores. Se requieren una atención integrada que contemple la prevención-promoción y asistencia al trabajador con este tipo de trastornos, así como de los derivados de factores psicosociales en el ámbito laboral. Actualmente existe un amplio acuerdo entre profesionales y gestores acerca de que debe priorizarse la atención en los Servicios de Salud Mental a las personas que padecen un trastorno mental grave, ya que son las que suelen tener una mayor discapacidad derivada del padecimiento del mismo. Para ello es necesario disponer de instrumentos que mejoren el diagnostico precoz de esos casos, así como de los recursos necesarios que permitan realizar un tratamiento efectivo. España se encuentra dentro del grupo de países con alto consumo alcohólico. Entre los trastornos relacionados con sustancias, el abuso y la dependencia del alcohol son los trastornos más frecuentes, por lo que es necesario desarrollar programas de prevención de estos trastornos con detección de sustancias en el trabajo y programas de ayuda al empleado que ya han demostrado su eficacia.

    In the nineties, the Instituto de Investigaciones Electricas (IIE) Electrical Equipment Management (GEE) was restricted to make the diagnosis of generators, transformers, switch boards and cables, without considering the global operating conditions. With the experience acquired in different services it was verified that, inclusively when this equipment is correctly designed, it can be subjected to unfavorable operative conditions, which causes an accelerated deterioration to the degree of producing a fault. In agreement with this, the GEE settled down new line of development named Analysis of the network effect on the electrical equipment, that analyzes the behavior of the equipment originated by work abnormal causes, including the network configuration effect. [Spanish] En la decada de los noventa, la Gerencia de Equipos Electricos (GEE) del IIE se limitaba a realizar el diagnostico de generadores, transformadores, tableros de distribucion y cables, sin considerar las condiciones globales de operacion. Con la experiencia adquirida en diferentes servicios se comprobo que, inclusive cuando estos equipos esten correctamente disenados, pueden verse sometidos a condiciones de operacion desfavorables, lo que ocasiona un deterioro acelerado al grado de producir una falla. De acuerdo con esto, la GEE establecio una nueva linea de desarrollo de nominada Analisis del efecto de la red en los equipos electricos, que analiza el comportamiento de los equipos originado por causas anormales de trabajo, incluido el efecto de la configuracion de la red.

    El presente estudio tiene por objeto desarrollar un diagnostico de la inserción integrada de la ética en la carrera de medicina brasileña con una metodología de aprendizaje basada en problemas y describir las percepciones de actitudes éticas de los estudiantes y egresados. El diseño metodológico es un estudio de caso, descriptivo y documental, con abordaje cualitativo y cuantitativo. La muestra de esta investigación ha sido constituida por 120 estudiantes y 40 egresados de dos promociones del Curso de Medicina de la ESCS. Este proyecto fue aprobado por el Comité de Ética en Investigación - SES/DF. Los estudiantes y egresados de la ESCS demostraron un buen manejo en el abordaje de los conflictos éticos y respeto a los pacientes. Sin embargo, el análisis de sensibilidad ética mostró una fragilidad en las percepciones y aptitudes inapropiadas de los estudiantes de la carrera de medicina, identificada básicamente en los años iniciales, que necesitan más discusiones sistematizadas sobre los aspectos éticos y bioéticos integrados a las actividades prácticas para estimular y fortalecer la reflexión ética de los estudiantes.
