    En América Latina, la década de 1980 estuvo signada por la transición a la democracia de un conjunto de países que durante largos años habían vivido bajo dictaduras militares de distinto signo. El fin de la guerra fría y el derrumbe de los denominados “socialismos reales” volvió crucial ese tema también en Europa Oriental y en menor medida en Asia Central e incluso en Africa. Sin embargo, lo que a algunos les pareció el fin de la historia fue por el contrario el inicio de un nuevo capítulo, m...

Seguiremo inizialmente i cambiamenti nella concezione del linguaggio e del significato del filosofo austriaco utilizzandoli come traccia per registrare le corrispondenti revisioni degli obiettivi, delle tecniche e delle forme del far filosofia da lui proposte. Cercheremo poi di analizzare la pratica filosofica prospettata dal Wittgenstein maturo evidenziandone alcuni aspetti che ci consentiranno di qualificarla come clinica.

    2014-09-01

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

    Scientific communication knowledge is specifically based in the analysis of the bibliographic references inside the publications. Pattern and laws determining the information consumption in the items of the journal Medicina Clinica are investigated in the present study as its own aim. An analysis was performed on the 13,286 references downloaded from 618 papers published by the journal in 1990. With dBASE IV was generated a database for the management of the information; data was distributed in several tables through criteria of age, documentary types, countries, journals and Bradford zones. The analysed references belong to 1,241 different journals, 110 from Spain. Being two thirds of the total sum, the publications from United States and United Kingdom have received more citations than those from Spain. The publications from european countries, like France, Germany and Italy, are scarcely present. Bradford core is constituted by the journals Medicina Clinica and The Lancet. The analysis of the bibliographic references available from the articles in this journal is able to produce knowledge on the information consumption by the practitioners; its usefulness as a complementary utility to the Indice de Citas e Indicadores Bibliométricos de Revistas Españolas de Medicina Interna y sus especialidades 1990 must be considered.

    The year 2017 marks the centenary of the death of the Italian scientist Pier Diego Siccardi (1880-1917), one of Luigi Devoto's assistants at the "Clinica del Lavoro" in Milan. To commemorate Siccardi and to describe the activities of the physicians of the "Clinica del Lavoro" during World War I. A comprehensive analysis was conducted on scientific papers written by Pier Diego Siccardi and by other physicians belonging to the Clinica del Lavoro, in the period 1915-1918. During the Great War, the Clinica del Lavoro became a military hospital, even though it indirectly maintained a role in Occupational Health, assisting women who had started to work to replace the men sent to the front. Devoto and his assistants were drafted as Army doctors, but continued their research activities while at the front; focusing on the diseases that affected the soldiers, mainly infections. Bleeding fevers and jaundice were endemic among Italian troops, but their etiology was unknown. Pier Diego Siccardi identified this syndrome as an infection caused by a spirochete, and was the first one to isolate the infectious agent. Siccardi prematurely died of the same disease as a consequence of a laboratory accident, which provided further confirmation for his research. The heroic life of Siccardi and his tragic death testify the important activities of the scientists of the "Clinica del Lavoro" in the years of the Great War.

  17. OC ToGo: bed site image integration into OpenClinica with mobile devices

    2014-03-01

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

    To identify the chief complaints and demographics at Clinica Esperanza, a student-run free clinic for an underserved Hispanic population. A retrospective chart review of patient files from 2005 through 2010 was undertaken, as approved by the University of Tennessee Health Science Center's Institutional Review Board. From 2005 through 2010, Clinica Esperanza fielded 2551 patient visits, consisting of 951 unique patients, 609 females and 342 males. Mean age was 34 years, and 60% of patients presented once, while 13% followed up for 1 year, 9% for 2 years, 6% for 3, 6% for 4, and 4% for 5. "Pap smear," "abdominal pain," and "follow-up lab results" ranked, in order, as the 3 top chief complaints. Resulting data have led to several improvements. The clinic has remained open weekly to improve patient continuity. With the top 10 chief complaints identified, they are better addressed. More funding is allocated for speculums and proper training of Pap smear technique. Systematic reporting of lab results is being implemented. Physical therapists and pharmacists now participate to address musculoskeletal and medication-based needs, respectively. A volunteer gastroenterologist has been recruited to provide specialized care for abdominal pain. An electrocardiogram machine is now used to evaluate chest pain. To improve student-patient communication, online language learning modules have been created. Based on these data, improvements in health care services have been made, including better continuity, emphasis on top chief complaints, and provider education in medical Spanish. Future plans include on-site pharmacy, smoother referrals, and similar clinics on the University of Tennessee Health Science Center's other campuses.

    There is increasing interest in research, prevention and management of mobbing in the field of occupational psychosocial risks. To describe mobbing and its health effects by analysis of the cases examined from 1997 to 2003 at the Department of Occupational Health "Clinica del Lavoro Luigi Devoto" in Milan. A total of 226 clinical records of patients who reported a mobbing situation when undergoing medical examination were selected out of 2455 patients examined for stress-related disorders. The percentage of women was higher (53.1%) than in men (46.9%) with a prevalent age range of 35-54 years. There was a great variety of jobs, especially white-collars and workers in large service companies. In one third of the cases, mobbing occurred within 4 years from beginning of employment and mostly after company reorganization and management changes. The most frequent negative acts included social isolation and demotion. The most frequent symptoms were exhaustion, sleep, mood and sexual disorders. The number of symptoms was not related to the duration of mobbing but to the number and frequency of negative actions. 61.1% of the subjects took psychotropic drugs. Occupational health physicians play an essential role in primary prevention (information on occupational risks) and in early diagnosis and rehabilitation and could act as mediators between workers and enterprises.

    Full Text Available La capacidad para hablar en público es una habilidad esencial para los administradores y otros profesionales. Sin embargo, muchas presentaciones son descritas como malas, aburridas, sin foco o incomprensibles. Uno de los principales errores es la falta de ayudas visuales que estén bien diseñadas; ejemplos comunes de ello son una excesiva cantidad de texto, el uso de fondos de bajo contraste, letras muy pequeñas para su lectura y el abuso de efectos artísticos, entre otros. En este trabajo se presentan los resultados de una revisión sistemática para responder la pregunta: ¿Qué es una ayuda visual correctamente diseñada?. Se encontró que, aplicando varios principios básicos y simples de diseño gráfico, es posible obtener ayudas visuales efectivas. Adicionalmente, se presentan varios ejemplos.

    Full Text Available El objeto de este trabajo consistió en evaluar el efecto de las diferentes presentaciones comerciales del fruto de plátano Hartón (Musa AAB en racimos, en bolsas: presentaciones de 10 unidades y desgranado en cestas de 22 Kg sobre la relación costo-beneficio de los productores de la cuenca del Lago de Maracaibo. La investigación fue de tipo aplicada con un diseño experimental de campo, de bloques completos, al azar generalizado, La unidad experimental fue la pesada, compuesta por racimos de plátano hasta llegar a los 300 kg. Se realizaron mediciones de las variables: número de racimos, masa del racimo (kg, número de manos, número de dedos, kilos por cestas, ingresos, costos variables y la relación costo/beneficio. Se efectuó análisis de varianza y pruebas de Tukey con el paquete estadístico S.A.S. versión 9.1. Los resultados obtenidos reflejaron que la presentación en cestas (kilogramos fue la forma de presentación comercial que generó mejor relación costo-beneficio a los productores de plátano de dicha zona. Los productores de plátano dependieron de la modalidad de camionero-comerciante para la venta de sus frutos. La caracterización de la pesada de plátano como unidad de venta presentó una media de 223,44 manos, 41 racimos por pesada y 1.104,3 frutos de plátano. Se recomienda que los productores de plátano de ahora en adelante utilicen la forma de presentación comercial en cestas, lo que les generará mayores ingresos

    Virtual-reality-based assessment may be a good alternative to classical or computerized neuropsychological assessment due to increased ecological validity. ClinicaVR: Classroom-CPT (VC) is a neuropsychological test embedded in virtual reality that is designed to assess attention deficits in children with attention deficit hyperactivity disorder (ADHD) or other conditions associated with impaired attention. The present study aimed to (1) investigate the diagnostic validity of VC in comparison to a traditional continuous performance test (CPT), (2) explore the task difficulty of VC, (3) address the effect of distractors on the performance of ADHD participants and typically-developing (TD) controls, and (4) compare the two measures on cognitive absorption. A total of 33 children diagnosed with ADHD and 42 TD children, aged between 7 and 13 years, participated in the study and were tested with a traditional CPT or with VC, along with several cognitive measures and an adapted version of the Cognitive Absorption Scale. A mixed multivariate analysis of covariance (MANCOVA) revealed that the children with ADHD performed worse on correct responses had more commissions and omissions errors than the TD children, as well as slower target reaction times . The results showed significant differences between performance in the virtual environment and the traditional computerized one, with longer reaction times in virtual reality. The data analysis highlighted the negative influence of auditory distractors on attention performance in the case of the children with ADHD, but not for the TD children. Finally, the two measures did not differ on the cognitive absorption perceived by the children.

Avere l'impressione di vivere in una casa abitata, testimoniare l’apparizione di OVNI, interrogarsi sulle possibilità di influenze telepatiche o anche conservare per sé la sensazione irreale di uscire “fuori dal corpo”, sono alcuni esempi di ciò che provano queste persone. L'eterogeneità di queste testimonianze le classifica spesso nella categoria delle "esperienze vissute come paranormali". Se tali resoconti sono sempre pervenuti agli esperti, si deve ai recenti lavori di ripristino dell'ascolto di queste persone.

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

    The research of the sentinel lymph node in early breast cancer, an already worldwide established method, was standardized at the teaching hospital 'Hospital das Clinicas' in Belo Horizonte (MG, Brazil). This standardization was carried out from December 2000 through December 2002, in which 39 patients were included in a learning curve and method validation. The applied methodology is based on the combination of a lymphoscintillography and the blue stain. A periareolar colloid 99m Tc injection was given 24 hours before the surgery. The blue dye was injected in the peritumoral region during the surgery. The sentinel lymph node was identified by the blue color pattern of the lymph node and by the use of a portable gamma probe detector. Radioactive contamination was evaluated before, during and after the surgery. The measurement of the radioactivity of the breast area was taken by using a GM detector and an ionization chamber on a humid piece of gauze (passed on the breast area), from which the radioactivity was recorded as well as the gloves used during the surgery, and the gauzes with contaminated blood. The sentinel lymph node identification rate was found to be 95%, there was a false negative rate of 4,8% and a predictive negative value (PNV) of 94%. The identification figures, the predictive negative value and the false negative rate were similar to the figures found in technical literature. The technique of the biopsy of the sentinel lymph node (BSL) is the method chosen for staging patients with invasive breast cancer and with clinically negative results for the armpit. The combined method using radio-colloid and the stain is the most indicated. There is a minimum radio isotopic contamination and there is scarcely any danger for the patient or the medical staff involved in the procedure. (author)

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

    The efficacy of cognitive stimulation in the progression to dementia is verified in patients with mild cognitive impairment, from the Clinica de Memoria of the Hospital Nacional de Geriatria y Gerontologia, between September 2008 and September 2013. A sample of 190 patients of the Metropolitan Area, the majority of female, complete primary, with self-care, aged 70 to 79 years are selected. The investigated group has had a history of hypertension, diabetes mellitus to a lesser extent and some degree of associated sensory deficit. The evolution time of memory loss presented is 2.6 years at the time of the medical evaluation. The most common cognitive impairment in the study has been the multiple dominion amnesia, followed by the non-amnesic dominion multiple. The etiology has leaded the degenerative, followed by vascular and thirdly the deficit of vitamin B12. Patients with mild cognitive impairment almost half of the cases have had neuro-behavioral disorder, being the depression most frequent, followed by anxiety and apathy. Patients have been partial independent in ABVD and dependent on AIVD. Absenteeism to dating has existed both in Clinica de Memoria; but mainly to the appointment with psychology. During the study it is determined that the deterioration was developed without progress to dementia, relatives have reported cognitive stability in more than half of the cases, only 18 patients have progressed to dementia. In the process only 29 patients have concluded and were reevaluated; without being able to demonstrate that the cognitive stimulation delays the cognitive deterioration to the dementia, but nevertheless; this result is given without unduly discrediting cognitive stimulation as a non-pharmacological measure for the prevention and delaying of dementia.

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

    Full Text Available INTRODUCCIÓN: El tumor de Masson o hemangioendotelioma vegetante intravascular, es una hiperplasia endotelial  papilar hacia el interior del vaso pudiendo ocluirlo y trombosarlo con necrosis e infartos locales, constituyendo tumoraciones rojizas irregulares bien delimitadas de localización preferente en piel y riñón, siendo muy raros en cavidad oral. Son elásticos no indurados, depresibles y frágiles, con crecimiento lentamente progresivo . MATERIAL Y MÉTODOS:Presentamos dos casos . Varón afecto de hematemesis repetidas sin identificarse origen inicialmente, demostrándose tumor de Masson de paladar duro oculto por prótesis dental, que fue resecado mediante pinza bipolar previa infiltración con suero perilesional para devascularizarlo. El segundo fue una mujer  que en relación con la ingesta presentó cuadro de hematemesis importante. La valoración de Urgencias y la endoscopia digestiva no identificaron el origen del sangrado en tubo digestivo, aunque la endoscopista identificó nuevo sangrado desde cavidad oral. La exploración ORL objetivó una pequeña tumoración rojiza de apariencia vascular en zona de mordida izquierda, sangrante al mínimo roce, cuya resección se realizó de urgencia sin incidencias, con idéntica técnica y diagnóstico anatomopatológico. Posteriormente, se constató el antecedente de episodios previos de menor cuantía. DISCUSIÓN: Los tumores de Masson son muy raros en tubo digestivo y excepcionales en cavidad oral. Se han relacionado con irritaciones repetidas o traumatismos locales,hematomas encapsulados o preexistencia de otras lesiones vasculares. Estos factores parecen haber acontecido en nuestros pacientes (roce de prótesis dental en paladar y mordidas de repetición. Son masas de lento crecimiento en las que se producen con frecuencia fenómenos trombóticos. Sin embargo, el roce de su superficie puede dar lugar a sangrados importantes como en estos casos. Deben diferenciarse de tumores malignos, principalmente el angiosarcoma, del que se distingue por su encapsulamiento, buena delimitación y la ausencia de atipias celulares. El tratamiento es quirúrgico, requiriendo excisión completa amplia así como suprimir los factores irritantes. En nuestros pacientes, una vez identificado el origen del sangrado, se realizó resección simple del tumor inyectando previamente habones de suero fisiológico perilesionales para reducir su vascularización y utilizando electrocauterio mediante pinza bipolar sin incidencias y sin recidiva.  CONCLUSIÓN : El tumor de Masson es una curiosidad que raramente da lugar a situaciones de riesgo como las descritas, pero que debe ser diagnosticada correctamente y diferenciada de otros tumores vasculares. La sospecha de etiología irritativa-traumática, como en estos pacientes por su relación con prótesis dental en el primero y mordidas en la segunda es clara. Deben evitarse traumatismos repetidos que puedan producir recidivas y sangrados. La exploración ORL minuciosa retirando prótesis y visualizando todos los recovecos de la vía aerodigestiva superior y de la boca en particular ante todo sangrado oral es esencial.

    Full Text Available A wide variety of opportunistic pathogens has been detected in the tubing supplying water to odontological equipment, in special in the biofilm lining of these tubes. Among these pathogens, Pseudomonas aeruginosa, one of the leading causes of nosocomial infections, is frequently found in water lines supplying dental units. In the present work, 160 samples of water, and 200 fomite samples from forty dental units were collected in the city of Barretos, State of São Paulo, Brazil and evaluated between January and July, 2005. Seventy-six P. aeruginosa strains, isolated from the dental environment (5 strains and water system (71 strains, were tested for susceptibility to six antimicrobial drugs most frequently used against P. aeruginosa infections. Susceptibility to ciprofloxacin, followed by meropenem was the predominant profile. The need for effective means of reducing the microbial burden within dental unit water lines is emphasized, and the risk of exposure and cross-infection in dental practice, in special when caused by opportunistic pathogens like P. aeruginosa, are highlighted.Uma ampla variedade de patógenos oportunistas tem sido detectadas nos tubos de alimentação de água dos equipos odontológicos, particularmente no biofilme formado na superfície do tubo. Entre os patógenos oportunistas encontrados nos tubos de água, Pseudomonas aeruginosa é reconhecida como uma das principais causadoras de infecções nosocomiais. Foram coletadas 160 amostras de água e 200 amostras de fomites em quarenta clinicas odontológicas na cidade de Barretos, São Paulo, Brasil, durante o período de Janeiro a Julho de 2005. Setenta e seis cepas de P. aeruginosa, isoladas a partir dos fomites (5 cepas e das amostras de água (71 cepas, foram analisadas quanto à susceptibilidade à seis drogas antimicrobianas freqüentemente utilizadas para o tratamento de infecções provocadas por P. aeruginosa.

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

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

    Proteins irradiation leads to structural alterations resulting in activity and function loss. This process has been useful to detoxify animal venoms and toxins, resulting in low toxicity products which increased immunogenicity. The Bothrops jararacussu venom behaves as a weak immunogen and its lethal activity in not neutralized by either autologous, heterologous or bothropic polyvalent antisera. This venom is markedly myotoxic and and the commercial bothropic antiserum does not neutralize this activity, because of this low immunogenicity of the myotoxins. This present work was done in order to evaluate the possibility of irradiating Bothrops jararacussu, intending to increase the immunogenicity of the myotoxic components, leading to productions of myotoxins neutralizing antibodies. Bothrops jararacussu venom samples were irradiated with 500, 1000 and 2000 Gy of {sup 60} Co gamma rays. A 2.3 folds decrease of toxicity was observed for the 1000 Gy irradiated samples while the 2000 Gy irradiated sample was at least 3.7 folds attenuated. On the other hand, the 500 Gy did not promote any detoxification. Electrophoresis and HPLC data indicate that the irradiation lead to the formation of high molecular weight products (aggregates). The proteolytic and phospholipasic activities decreased in a dose dependent manner, the phospholipases being more resistant than the proteases. Both the animals (rabbit) immunized with either native or 2000 Gy irradiated venom produced native venom binding antibodies, a slightly higher titer being obtained in the serum of the rabbit immunized with the irradiated samples. Western blot data indicate that the anti-irradiated venom Ig Gs recognised a greater amount of either autologous or heterologous venom bands, both sera behaving as genus specific. The anti-native serum did not neutralize the myotoxic activity of native venom, while the anti-irradiated one was able to neutralize this activity. (author). 56 refs., 7 figs.

    Irradiation of crotoxin and its subunits with 2,000 Gy of {gamma}-rays from {sup 60} Co source leads to aggregation and generation of lower molecular wight breakdown products. Aggregates separated by gel filtration retain at least part of their higher-ordered structure, based on their reactivity with monoclonal antibodies known to react with conformation epitopes in native crotoxin. These same aggregates can serve as antigens to raise antisera that cross-reacts and neutralizes crotoxin. Compared with native crotoxin, aggregates appears less myotoxic, are largely devoid of phospholipase activity, and are virtually non-toxic in mice. These results indicate that irradiation of toxic proteins can promote significant detoxification, but still retain many of the original antigenic and immunological properties of native crotoxin.

    The serum production in Brazil, the only effective treatment in cases of snakebites, uses horses that although large size, have reduced l lifespan compared with horses not immunized. Ionizing radiation has been shown as an excellent tool in reducing the toxicity of venoms and toxins isolated, and promote the achievement of better immunogens for serum production, and contributing to the welfare of serum-producing animals. It is known, however, that the effects of ionizing radiation on protein are characterized by various chemical modifications, such as fragmentation, cross-linking due to aggregation and oxidation products generated by water radiolysis. However, the action of gamma radiation on toxins is not yet fully understood structurally and pharmacologically, a fact that prevents the application of this methodology in the serum production process. So we proposed in this paper the characterization of crotamine, an important protein from the venom of Crotalus durissus terrificus species, irradiated with {sup 60}Co gamma rays. After isolating the toxin by chromatographic techniques and testing to prove the obtaining of pure crotamine, it was irradiated with gamma rays and subjected to structural analysis, Fluorescence and Circular Dichroism. Using high hydrostatic pressure tests were also conducted in order to verify that the conformational changes caused by radiation suffer modifications under high pressures. From the pharmacological point of view, muscle contraction tests were conducted with the objective of limiting the action of crotamine in smooth muscle as well as the change in the action of toxin caused structural changes to the front. Analysis of Circular Dichroism and Fluorescence showed changes in structural conformation of crotamine when subjected to gamma radiation and that such changes possibly occurring in the secondary and tertiary structure of the protein. The observed in pharmacological tests showed that the irradiated crotamine was less effective in lowering the vas deferens twitch in rats in comparison to native crotamine. In addition, the behavior of irradiated toxin in tonic contraction, modulated by noradrenaline, was different from that observed for the native toxin. (author)

Aún así, faltan registros sobre estas patologías en las instituciones deportivas, sobretodo en el atletismo brasileño, donde pocos son los clubes que poseen servicios de asistencia de la salud. La ausencia de tales registros, estudios en el área de Salud Pública, se utilizan otros recursos epidemiológicos para colectas, tales como las consultas de morbilidad referida. A partir de esta escasez de información y de la facilidad de obtención de datos junto a los propios atletas, se objetivó, para esta pesquisa, levantar informaciones sobre las LD referidas por los atletas de alto rendimento, retrocediendo ocho meses, y comparándolas con los registros de historias clínicas. Por lo tanto, fueron tomados veinticinco atletas de elite, dieciseis de género masculino y nueve del femenino, con edades de 25,7 ± 4,4 años, altura de 1,74 ± 0,10 m, peso 70,4 ± 13,15 kg e tiempo médio de entrenamiento de 8,38 ± 4,06 años.

    Full Text Available Este artículo está basado en una investigación realizada sobre problemáticas familiares de 133 pacientes interconsultados y atendidos por Trabajo Social en los servicios de internación de la Clínica Universitaria Bolivariana (CUB entre febrero-julio de 2013.1 Se utilizó un diseño mixto, integrando aspectos cuantitativos y cualitativos para describir las familias, variables de la atención ofrecida por trabajo social y la manera como se organizaban las familias para el cuidado del paciente en su hospitalización. Se encontraron varias configuraciones familiares, un porcentaje alto atravesando ciclo vital de adulto o anciano. El mayor número de remisiones corrieron por cuenta del médico internista y correspondieron a situaciones catalogadas por trabajo social como “problemas relacionados con otros hechos estresantes que afectan la familia”. El tipo de intervención en el que fueron atendidas fue el acompañamiento. Algunas de las familias, encontraron soporte entre sus miembros, amigos, vecinos, cuidadores formales e informales y en instituciones que por su competencia deben brindarlo. La ausencia de estos apoyos se constituye el principal motivo de remisión a trabajo social.

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

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

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

    Evidence has shown the effectiveness of risk factor management in reducing mortality and morbidity from cardiovascular disease (CVD). An audit of a nurse CVD risk assessment programme undertaken between November 2005 and December 2008 in a Northland general practice. A retrospective audit of CVD risk assessment with data for the first entry of 621 patients collected exclusively from PREDICT-CVDTM, along with subsequent data collected from 320 of these patients who had a subsequent assessment recorded at an interval ranging from six months to three years (18 month average). Of the eligible population (71%) with an initial CVD risk assessment, 430 (69.2%) had afive-year absolute risk less than 15%, with 84 (13.5%) having a risk greater than 15% and having not had a cardiovascular event. Of the patients with a follow-up CVD risk assessment, 34 showed improvement. Medication prescribing for patients with absolute CVD risk greater than 15% increased from 71% to 86% for anti-platelet medication and for lipid lowering medication from 65% to 72% in the audit period. The recently available 'heart health' trajectory tool will help patients become more aware of risks that are modifiable, together with community support to engage more patients in the nurse CVD prevention programme. Further medication audits to monitor prescribing trends. Patients who showed an improvement in CVD risk had an improvement in one or more modifiable risk factors and became actively involved in making changes to their health.

    In recent years, with an increasing emphasis on time spent in ambulatory training, educators have focused attention on improving the residents' experience in continuity clinic. The authors sought to review the factors associated with physician trainee satisfaction with outpatient ambulatory training. A systematic literature review was conducted for all English language articles published between January 1980 and December 2016 in relevant databases, including Medline (medicine), CINAHL (nursing), PSYCHinfo (psychology), and the Cochrane Central Register of Controlled Clinical Trials. Search terms included internship and residency, satisfaction, quality of life, continuity of care, ambulatory care, and medical education. We included studies that directly addressed resident satisfaction in the ambulatory setting through interventions that we considered reproducible. Three hundred fifty-seven studies were reviewed; 346 studies were removed based on exclusion criteria with 11 papers included in the final review. Seven studies emphasized aspects of organizational structure such as block schedules, working in teams, and impact on resident-patient continuity (continuity between resident provider and patient as viewed from the provider's perspective). Four studies emphasized the importance of a dedicated faculty for satisfaction. The heterogeneity of the studies precluded aggregate analysis. Clinic structures that limit inpatient and outpatient conflict and enhance continuity, along with a dedicated outpatient faculty, are associated with greater resident satisfaction. Implications for further research are discussed.

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

    The Prevention and Integrated Control of Contamination Act (Ley de Prevencion y control Integrado de la Contaminacion) was passed by the Spanish parliament on 13 June. the basic purpose of this law is to prevent, reduce and control contamination of the atmosphere, water and soil caused by the most contaminating industrial activities. Public sector bodies and private companies in Spanish have been invited by the European Union to adopt new technologies in their production processes with a view to cutting down emissions, minimising or re-using waste, and pre-treating or purifying effluents. I t is therefore extremely appropriate to make available information on new tools of analysis that allow users to take preventive measures to reduce the impact their activity may have on the environment. A fundamental parameter in monitoring water is the Biological Demand for Oxygen (BOD). Various different chemical, physical and biological techniques have been developed to solve the problem of continuously monitoring the BOD and toxicity of water. This study carried out a comparative analysis of these techniques, describing the advantages and disadvantages of applying them to water quality control. At the present time it can be said that the BOD microbiosensor. Multisens 304 is the best available technology for monitoring this parameter. The articles tells us why. (Author) 8 refs.

Se presenta con mayor frecuencia en mujeres añosas y es precedido por un evento de estrés, ya sea físico o psíquico. La fisiopatología aún no está aclarada y se proponen diversas teorías. La de mayor peso es la que postula una afección secundaria a la descarga de catecolaminas desencadenada por el estrés, sobre un corazón incapaz de mantener una respuesta inotrópica adecuada. Se presentan cuatro casos de pacientes atendidos en nuestro hospital que se manifestaron con síntomas sugerentes de infarto agudo de miocardio asociados a insuficiencia cardiaca, en el contexto de un episodio estresante. Los síntomas preponderantes fueron dolor precordial opresivo y disnea. En el ECG se evidenciaron tanto supradesnivel del segmento ST, como inversión de la onda T. Todos los pacientes presentaron la imagen ecocardiográfica típica de discinesia apical, y todos tuvieron en la cinecoronariografía coronarias normales. Cabe destacar que tanto el ECG, como el ecocardiograma volvieron a la normalidad a partir de las dos semanas.A syndrome of apical ballooning, with ECG mimicking acute myocardial infarctation, mild or no enzymatic changes, and normal coronary angiogram was described in 1990. It presents mainly in middle aged and elderly women and it is preceded by stress triggering circumstances. Several mechanisms have been proposed although the precise cause remains unclear. The most accepted theory proposes the interaction of catecholamines and an inadequate inotropic response. We report four cases that presented with chest pain and sudden onset of heart failure, all patients had physical or emotional stress as a triggering factor. On ECG, ST segment elevation and inverted T waves were observed in the acute phase. All patients had typical echocardiogram image and normal coronary angiogram. Both ECG and echocardiogram returned to normal within two weeks.

    Full Text Available El foramen mentoniano accesorio es un orificio adicional al foramen mentoniano que se localiza en la cara anterolateral externa del cuerpo mandibular y que se conecta con el conducto dentario inferior.  Su ubicación es posteroinferior al foramen mentoniano.  De acuerdo a su clasificación también se lo conoce como foramen mental doble, foramen mental adicional, foramen mental múltiple, foramen mental accesorio o foramen mandibular bucal suplementario. Su frecuencia de aparición varía del 1% al 10 %, cuando son unilaterales y del 0,47% al 1,2% cuando son bilaterales.  El  foramen mentoniano accesorio es una rara variante anatómica de poca frecuencia pero de gran relevancia clínico-quirúrgica ya que está asociado a un paquete vasculonervioso por lo cual es necesario su diagnóstico radiográfico ya sea por métodos convencionales o por alta resolución para evitar posibles complicaciones en los diferentes procedimientos odontológicos. Se presenta un caso de foramen mentoniano accesorio de un paciente remitido al Servicio de Radiología de la Facultad de Odontología de la UNC. La tomografía computada constituye el estudio por imágenes de excelencia ante la presunción de un foramen accesorio ya que los diferentes cortes tomográficos y la reconstrucción 3D nos permiten localizarlo de manera precisa e inequívoca. Constituye generalmente un hallazgo radiográfico o se observa durante procedimientos quirúrgicos al quedar al descubierto por el desplazamiento de los tejidos blandos. Cuando se localiza antes de cualquier procedimiento odontológico se deben tomar todos los recaudos necesarios para evitar daño del paquete vasculonervioso y futuras complicaciones como hemorragias o parestesias, principalmente en prácticas como la colocación de implantes dentales o las apicectomías. Accessory mental foramen (AMF is defined as any openings in addition to mental foramen, with connection to the mandibular canal in the anterolateral aspect of mandible. According to its classification, an AMF is known as double mental foramen, additional mental foramen, multiple mental foramen, supplementary mandibular buccal foramen. The accessory mental foramen is a radiological finding or is detected during surgical procedures. Its prevalence ranges from 1.4 to 10% when it is unilateral and ranges from 0,47% to 1,2% when it is bilateral. Accessory mental foramen is an important and rare anatomical variation associated with a neurovascular bundle. Its prevalence is low. The diagnosis by conventional radiological methods or three-dimensional radiographic imaging techniques is effective to avoid complications in dental procedures. An accessory mental foramen case of a male patient referred to the Department of Radiology at the National University of Córdoba School of Dentistry is reported. The computed tomography is the most accurate imaging modality for the identification of an accessory foramen through multiplanar reformatted images and three dimensional images. When the existence of AMF is identified before dental procedures, appropriate actions should be taken to avoid damages of the neurovascular bundle and eventual complications such as hemorrhage and paresthesia principally in procedures like dental implant insertion or periapical surgery.

    We present a cardiac hydatid cyst in a seventeen year-old male, who was operated on, five years ago, for hydatid disease in the lung and in the liver. In the follow-up a Computed Tomography was carried out in which an intracardiac rounded image was visible, showing to be non-enhancing after endovenous contrast injection. Due to this characteristic, the history of hydatid disease and the high incidence of this entity in our country, an intracardiac hydatid cyst was suspected. The diagnosis was reinforced by real-time echocardiography and Magnetic Nuclear Resonance, and confirmed in the surgical intervention. (Author)

    Full Text Available In the last years Public Health Service has been trying to find out solutions in order to improve its health value added creation capacity. The implementation of the Day-surgery division mainly aims to follow that direction, since it enables the improvement of the ratio between efficacy, quality and healthcare suitability and on the other hand efficiency, costs and modality of better resources utilization. The centralization of Day-surgery activities proposes some innovative characteristics, concerning that it introduces an organizational model focused on needs and it performs the separation of the clinic and therapeutic activities from the ones involving the assistance. Both economic and qualitative advantages deriving from the changes stand out in term of: - high possibility of activities’ scheduling; - improved customer satisfaction; - rationalisation of day-hospital recovery, with positive effects on the inpatients; - improved hospital economic stability. This study was carried out with the support of the multiple-skill group composed of doctors, nurses, administrative staff as well as experts in the field of organisation with an aim to provide the full outline of the necessary competences. The proposed discussion reflects the multidisciplinary view of the problem and different perspectives. Each of them regards particular aspects and implications indicated as following: - clinical perspective, related to the possibility of day-surgery interventions both from the medical and the anaesthetic point of view; - organisational perspective, which refers to the possible day-surgery models in conjunction with the organisational model and their peculiarities; - operative perspective, which consist of the analysis of the ideal structural dimension, flows of activities among all services involved and the analysis of the productive capability; (number of necessary beds, staff dimension and a relapse of the operation activities needs; - economic perspective, focused mainly to provide the final valuation on the capacity of the project to contribute to the improvement of the hospital.

  8. Las experiencias clinicas de los estudiantes de enfermeria: Estudio de caso hacia la integracion de la mentoria

    Rivera Rodriguez, Ivelisse

    Clinical experiences are an essential part of the training of future nursing professionals. The period of clinical experience aims to develop in the student the necessary skills to practice as a nursing professional, when the academic program ends. This case study aimed to understand the opinion and explore the perception of faculty, clinical instructors, and nursing students on the meaning, contributions and challenges presented during clinical experiences. Among the themes explored in the focus groups were the meaning and importance to learning about the profession of clinical experiences, teaching strategies used during the practice scenarios, didactic relationships developed among students, clinical instructors, and teachers. The goal was to learn from all participants about what they do, their expectations, and the challenges presented during the clinical experiences. A qualitative, descriptive and contextual research design was followed, which required conducting six focus groups to collect the information from the perspective of all the participants. Faculty, clinical instructors, and nursing students participated each in two focus groups. Collected data were transcribed, coded and analyzed in order to organize it under themes related to the research framework. The qualitative analysis of the focus groups revealed that nursing faculty and clinical instructors perceived clinical experiences as a very important element in the training of nursing students, but that coordination between the academy and practice scenarios is disconnected and needs improvement. They also expressed that they use various learning strategies during the clinical experiences, however, they recognize it needs more structure and suggested mentoring as a strategy to consider. They affirmed that mentoring could contribute positively to enhance the teaching-learning process. Clinical instructors understand they perform mentoring roles, but they would like to have a more defined role and structured process. Nursing students, also, recognized the importance of clinical experiences in their professional training. They expressed the need to improve the communication between the academy and the practice scenarios in order to reduce the levels of anxiety they experience when entering the clinical experiences. Nursing students also expressed the need to consider the use of different teaching strategies, such as mentoring, to improve clinical experiences.

    To review the radiological features of the phyllodes tumor, correlating them with the clinical presentation, histological type and response to treatment. Fifty phyllodes tumors in 29 patients aged 16 to 59 years (mean: 41 years) were analyzed retrospectively. The series included 12 cases of recurrence, 1 of bilateral tumor and 6 of multiple tumor. Forty-five lesions were studied by mammography and 36 by ultrasound. Clinically guided fine-needle aspiration cytology was performed in 8 cases. The pathological diagnosis was obtained by means of surgical biopsy in every case (31 benign and 19 malignant). Twenty-four patients underwent postoperative clinical and radiological follow-up for a mean period of 32 months. Mammography revealed the presence of a nodule or mass in 42 cases, asymmetrical density in two and a generalized increase in density in one: Multifocal lesions were detected in six cases. The size varied widely, with masses measuring >5 cm showing a greater probability of malignancy (p<0.01). Calcifications were observed in 13% of the cases. Ultrasound revealed the presence of heterogeneous, hypoechoic nodules, with cystic areas in five tumors, all of which were malignant (p<0.01). Local recurrence was detected in 31% of the cases and bone metastases in one. The phyllodes tumor is an uncommon fibroepithelial tumor that has a potential for recurrence and distant metastasis. Mammographic and ultrasound features are similar to those of the fibroadenoma, a lesion with which it is occasionally associated. Multiple lesions are not infrequent and it can present with calcifications. The presence of cystic areas and a tumor size of >5 cm are the only radiological findings that are statistically associated with malignancy. The recurrence rate is greater in malignant tumors than in benign lesions, especially in patients treated by tumor resection. (Author) 28 refs.

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

    Due to the increase in the average of the world population's life, people die each time to more age, this makes that the tissues of support of the human body, as those muscle-skeletal tissues, when increasing the individual's age go weakening, this in turn leads to the increment of the illnesses like the osteoporosis and the arthritis, that undoubtedly gives as a result more injure of the muscle-skeletal tissues joined a greater number of traffic accidents where particularly these tissues are affected, for that the demand of tissues muscle-skeletal for transplant every day will be bigger. The production of these tissues in the Bank of Radio sterilized Tissues, besides helping people to improve its quality of life saved foreign currencies because most of the muscle-skeletal tissues transplanted in Mexico are of import. The use of the irradiation to sterilize tissues for transplant has shown to be one of the best techniques with that purpose for what the International Atomic Energy Agency believes a Technical cooperation program to establish banks of tissues using the nuclear energy, helping mainly to countries in development. In this work the stages that follows the bank of radio sterilized tissues of the National Institute of Nuclear Research for the cadaverous donor's of muscle-skeletal tissue selection are described, as well as the processing and the clinical application of these tissues.

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for diagnostic radiology. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists based in the clinical setting. However, an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement (RCA) for Research, Development and Training related to Nuclear Sciences for Asia and the Pacific. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia-Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specializing in diagnostic radiology started in 2007 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experiences of clinical training programmes in Australia and New Zealand, the UK and the USA, and was moderated by physicists working in the Asian region. This publication follows the approach of the IAEA publication Training Course Series No. 37, Clinical Training of Medical Physicists specializing in Radiation Oncology. This approach to clinical training has been successfully tested in Thailand, with two other Member States currently undergoing testing, and is believed to be applicable to the medical physics community in general.

    We present the case of a boy with acquired immunodeficiency syndrome (AIDS) in whom ultrasound revealed the presence of acalculous cholecystitis. Abdominal ultrasound was essential in the initial diagnosis and the assessment of the response to treatment. This entity has rarely been reported in the pediatric radiology literature. In our patient, the cholecystitis may have been caused by infection, and the involvement of regional lymphatic obstruction in the pathogenesis is considered. (Author) 14 refs.

    To determine whether the presentation of brainstem tumors as diffuse or focal lesions showed any prognostic value in children. A retrospective review was carried out of the neuroradiological findings in 43 children with brainstem tumors, all of whom underwent computed tomography (CT) and 31 of whom underwent magnetic resonance (MR). The diffuse tumors (n=20) were all located in the pons, spreading to mesencephalon in 6 cases and to medulla oblongata in 1, and exhibiting exophytic growth, preferentially to the prepontine cistern. They presented homogeneous low attenuation in CT (90%) and decrease/increased signal intensity in T1/T2-weighted MR images (91.6%). Contrast uptake was observed in 20% of cases, with agreement between CT and MR. The patients showed a good initial response to treatment (70%), a high rate of relapse (80%) and a 5-year survival of 12%. The focal tumors were located in the pons (11 cases, spreading to the medulla oblongata in 2), mesencephalon (11 cases, 9 tectal and 2 peduncular) and medulla oblongata (1 case), and exhibited exophytic growth predominantly to the pontocerebellar junction and to the cerebellar peduncles. They showed a certain tendency toward heterogeneity (21.7%), toward isoattenuation in CT (47.8%) and isointensity in T1-weighted MR images (26.3%). CT showed a rate of tumor uptake of 26%, while the rate of contrast iptake was 58% MR. Fifty percent of these lesions responded well to therapy, with a recurrence rate of 28% and 4-year survival of 63%. Neuroimaging helps to define two basic patterns in brainstem tumors that play a role in prognosis. The diffuse tumor, which characteristically shows a good initial response to therapy, has a worse prognosis, probably reflecting its histological aggressiveness. (Author) 21 refs.

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

    1977-01-01

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

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

    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)

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

    The colorectal cancer is a serious health problem because of its high incidence. In Cuba, this disease is the fourth neoplasm in order of frequency with a rate of 17.1 per 100 000 inhabitants. With the objective of determining the precocious diagnosis of this complaint we carried out a prospective, longitudinal and descriptive study among geriatric patients with colorectal disease assisting to consultation at the policlinic 'Carlos Verdugo' of Matanzas in the period from January 2006 to December 2007. The studied parameters were age, genre, risk facts, presentation forms, localization, and endoscopic diagnosis of the disease. The results showed predominance of female sex (52,1 %), in ages from 60 to 69 years old (59.3 %), predominating risk facts like familiar antecedents (13,5 %), idiopathic ulcerative colitis (8.1 %), and an inadequate diet (35.1 %). The most used diagnostic method was colonoscopy (18 patients), with predominance of the rectosigmoidal cancer (15 cases), being the polypoid one the most common endoscopic kind (13 %). We concluded that generally there is not a precocious diagnosis of the colorectal cancer among geriatric patients, leading to a decrease of the healing possibilities and surviving of these patients

    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)

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

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

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)

    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.

    Objective: to evaluate the relationship between two year PSA nadir (PSAn) after brachytherapy and biochemical recurrence rates in prostate cancer patients. Materials and methods: In the period from January 1998 to August 2007, 120 patients were treated with iodine-125 brachytherapy alone. The results analysis was based on the definition of biochemical recurrence according to the Phoenix Consensus. Results: biochemical control was observed in 86 patients (71.7%), and biochemical recurrence, in 34 (28.3%). Mean PSAn was 0.53 ng/ml. The mean follow-up was 98 months. The patients were divided into two groups: group 1, with two year PSAn < 0.5 ng/ml after brachytherapy (74 patients; 61.7%), and group 2, with two year PSAn ≥ 0.5 ng/ml after brachytherapy (46 patients; 38.3%). Group 1 presented biochemical recurrence in 15 patients (20.3%), and group 2, in 19 patients (43.2%) (p < 0.02). The analysis of biochemical disease-free survival at seven years, stratified by the two groups, showed values of 80% and 64% (p < 0.02), respectively. Conclusion: levels of two year PSAn ≥ 0.5 ng/ml after brachytherapy are strongly correlated with a poor prognosis. This fact may help to identify patients at risk for disease recurrence. (author)

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

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

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

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

    A survey was conducted among the Brazilian clinical PET, with the purpose of investigating the activities administered to pediatric oncology patients and assess whether significant differences between the protocols adopted. In addition, this survey can cooperate to the suggestion diagnostic reference levels (DRLs) in nuclear medicine. Although the methodology for delivering doses by most clinics be based on patient's weight, the results showed variations of up to 191, 6% between the activities administered in clinics, even for similar devices. The average value of the distribution of activities reported was 4.46 {+-} 1,6 MBq /kg. These data demonstrate the need for harmonization and optimization of {sup 18}F-FDG/PET procedures, as well as training for professionals involved in the clinical routine.

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

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

    The research teaching methods aimed at the success of the higher education student in pharmacology and medicine courses in technical expertise in the fields of radiological protection, radiopharmacology and interventional radiology is extremely important in view of the progress of these sectors. The objective of this work is to propose a methodological sequence of teaching work with first-year students of pharmacy and medicine courses within a biophysical discipline where the integrated knowledge to clinical practice can be used for this purpose. The methodology was to assess individual learning of a group of N = 49 students of the first half in the age group of 17-19 years through conceptual acquisition by the traditional method of 'blackboard and chalk' and developed method that includes four pedagogical moments focused on the area health. An analysis of the evaluation student performance through Variance Analysis of a pathway showed improved scores with respect to the performance of application issues of knowledge concerning radiation protection and biological mechanisms of radiation with respect to the method of 'blackboard and chalk' with p < 0.05. Therefore, work with students with respect to the content in the form of six steps of clinical interest are a promising technique for radiation protection education in the early grades of college courses with experimental effectiveness.

    In recent years, medical imaging with hybrid techniques has widely accepted and employed in clinical routine. PET/MRI offers significant advantages, including excellent contrast and resolution and reduced ionizing radiation, as compared to well-established PET/ CT. Therefore, PET/MRI is a promising modality for oncologic imaging of some regions, such as brain, head and neck, liver and pelvis. This article set out to analyze clinical conditions that could benefit from PET/MRI imaging based on our caseload. The potential of PET/MRI to become the imaging modality of choice for assessment of neurologic and oncologic conditions associated with soft tissues is highlighted. Clinical aspects of PET/MRI and its application to clinical cases are illustrated with examples extracted from the authors' preliminary experience. (author)

Nowadays, it is known that insulin resistance and consequent hyperinsulinism seem to be the basis of the disorders characterizing it. That's why, it is not erroneous to think that in females with metabolic syndrome, whose physiopathological bases are insulin resistance and hyperinsulinism, there may appear clinical, humoral and ultrasonographic elements of the polycystic ovarian syndrome.

    For many years creatine kinase (CK) and CK-MB isoenzymes were used together with the ECG to confirm the presence of myocardial infarction. During the last decade newer cardiac markers have been introduced and immunological test systems developed for their quantification. Among these new markers, a prominent role has emerged for cardiac troponins (T or I). These technological advanced assays have shown greater sensitivity compared to "conventional cardiac enzymes;, thereby identifying patients with small--at times, microscopic--infarcts who would not have met defining criteria for myocardial infarction in an earlier era. Another major advantage shown by both cardiac troponins with respect to "conventional cardiac enzymes" is their ability to predict clinical outcome over a short- or long-term follow-up in patients with acute coronary syndromes, and this appears to be particularly relevant in patients with micronecrosis, who constitute a high-risk subgroup of unstable angina patients. Recently, myoglobin has also been widely applied as a marker. Although lacking in myocardial specificity, it is the earliest marker to show an increase after coronary occlusion. Thus, the combined use of myoglobin and a cardiospecific structural protein such as troponin T or I may prove an attractive strategy for biochemical testing in chest pain patients. With the routine use of these novel cardiac markers, fascinating opportunities are now open in the field of diagnostic classification (making the World Health Organization definition of myocardial infarction obsolete) and risk stratification in chest pain patients; opportunities that were unforeseen in the era of cardiac enzymes. However, the use of these markers has also posed some important questions on: a) the best and most cost-effective diagnostic strategy in chest pain patients; b) the remaining role of cardiac enzymes; c) the therapeutic consequences of a positive test result.

    A Quality Management System consists of several processes that qualify and quantify the performance of a service, minimizing the possibility of errors in the radiological diagnosis that may result in clinical consequences. One of these processes is the implantation of double reading, which consists in the evaluation of the report interpreted by a radiologist and the subsequent conference by another radiologist, through the analysis of archived PACS exams. The classification of the results of these analyzes was based on the recommendations of the American College of Radiology (ACR). Double reading is an extremely effective process for increasing the quality of the radiological report, in addition to contributing to the continuing education between the pairs.

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

    Full Text Available Introducción: Los tumores carcinoides son las neoplasias más frecuentes del apéndice cecal, se caracterizan por un crecimiento lento y curso clínico asintomático, su incidencia se calcula en 1-2 casos por cada 100,000 habitantes, se encuentran en menos del 1% de las apendicetomías y se presentan con mayor frecuencia en mujeres entre la cuarta a quinta época de la vida. Por lo general se trata de lesiones pequeñas que se diagnostican luego de la apendicetomía. Metodología El presente trabajo corresponde a una descripción de casos de tumor carcinoide del apéndice cecal, realizado en el laboratorio de patología MEGA, de la Clínica Ardila Lulle (CAL que incluye revisión de protocolos de especímenes quirúrgicos analizados entre enero 1 de 2000 y diciembre 31 de 2010. Resultados: Durante el periodo propuesto se encuentran cuatro casos de tumor carcinoide confinado al apéndice cecal en cuatro mujeres jóvenes. Tres de las lesiones presentan patrón histológico tipo A o insular y el restante un patrón tipo B o trabecular, en todos los casos se documentó reactividad con las sales de plata con la coloración de Fontana Masson y en los cuatro se encontró positividad con el marcador neuroendocrino cromogranina. Conclusión: Los tumores carcinoides de apéndice son lesiones de origen neuroendocrino, la mayoría circunscritas a la punta del órgano y de curso clínico indolente, sin embargo algunos de estos tumores tienen un comportamiento agresivo, que depende de su tamaño y de la actividad mitótica de sus células, por lo que se recomienda incluir en la evaluación diagnostica la cromogranina y el Ki67, marcadores neuroendocrino y de proliferación celular. Salud UIS 2011; 43 (2: 203-210Introduction: The carcinoids tumours are the most common neoplasm of the cecal appendix, are characterized by a slow growth and asymptomatic clinical course, its incidence is estimated at 1-2 cases per 100.000 inhabitants, are less than 1% of appendicectomies and occur most often in women between the fourth o fifth decade of life. Usually these are small lesions diagnosed after appendicectomy. Methodology: This work belongs to a description of cases of carcinoid tumor of cecal appendix, conduced in the MEGA anatomic pathology laboratory of Carlos Ardila Lulle Clinic (CAL, wich includes protocols review of surgical specimens analized between January 1, 2000 and December 31, 2010. Results: During the proposed period are four cases of carcinoid tumor confined to the cecal appendix in four young women. Three of the lesions have the A histological type or insular pattern, and the remainder have the B histological type or trabecular pattern, in all cases documented reactivity with silver salts with Masson-Fontana stain and all four were found positive with the neuroendocrine marker chromogragin. Conclusion: The carcinoid tumors of the apenddix are lesions of neuroendocrine origen, most of them located at the tip of the organ, and having a indolent clinical course; however some of these tumors have an aggressive behavior, which depends on its size and the mitotic activity of its cells, that's the reason why the diagnostic evaluation of neuroendocrine markers like chromogranin, and Ki67 (proliferation cell index are recommended.

    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.

    In this work a comparison of experimental and simulated relative doses of a clinical brachytherapy source was performed. A 5 x 5 x 7 cm{sup 3} phantom with a modified MAGIC-f gel was irradiated using a clinical {sup 192}Ir source and read using Magnetic Resonance Imaging. The Monte Carlo simulation package PENELOPE was used to simulate the dose distributions of the same radiation source. The dose distributions were obtained in two planes perpendicular to the source: one passing through the source's center and the other at 0.5 cm away from the source's center. The higher differences found between experimental and computational distributions were 12.5% at a point 0.62 cm from the source for the central plane and 8.6% at 1.3 cm from the source to the plane 0.5 cm away from the source's center. Considering the high dose gradient of these dose distributions, the results obtained show that the modified MAGIC-f gel is promising for brachytherapy dosimetry. (author)

    A comparison of experimental and simulated relative doses of a clinical brachytherapy source was performed. A 5 x 5 x 7 cm{sup 3} phantom with a modified MAGIC-f gel was irradiated using a clinical {sup 192}Ir source, Varian, model GammaMed Plus. The phantom was irradiated with 7,5 Gy, commonly used in gynecological treatments. The dose distributions readings were performed 24h after irradiation using Magnetic Resonance Imaging, weighted in T2, with repetition time of 6000 ms, echo-time of 15 ms, 16 echos and 0.40 mm pixel size. The same brachytherapy source was modeled in the Monte Carlo package PENELOPE to obtain dose distributions. The energy cutoff for electrons, photons and positrons was 100 keV, the primary particles condensation parameters remained the same at 0.3. The dose distributions were obtained in two planes perpendicular to the source: one passing through the source’s center and the other at 0.5 cm away from the source’s center in direction of the top of encapsulation. A comparison of the experimental results using the polymeric gel to the computational results showed maximum differences of 12.5%, at 0.62 cm from the source for the central plane, and 6.4% at 0.5 cm from the source for the superior plane. Considering the high dose gradient of these clinical brachytherapy sources, the results obtained in these work show that MAGIC-f gel with modified formulation, is promising for dosimetry in brachytherapy.

    In this work an analysis of the influence of the choice of the algorithm or planning system, on the calculus of the same treatment plan is introduced. For this purpose specific software has been developed for comparing plans of a series of IMRT cases of prostate and head and neck cancer calculated using the convolution, superposition and fast superposition algorithms implemented in the XiO 4.40 planning system (CMS). It has also been used for the comparison of the same treatment plan for lung pathology calculated in XiO with the mentioned algorithms, and calculated in the Plan 4.1 planning system (Brainlab) using its pencil beam algorithm. Differences in dose among the treatment plans have been quantified using a set of metrics. The recommendation for the dosimetry of a careful choice of the algorithm has been numerically confirmed.

    The present work is a proposal to assess, which is the efficiency in the use of radionuclides of clinical application in nuclear medicine service conjugated system with gold nanoparticles.To obtain the results needed for the interpretation of this combination, was using the Monte Carlo simulation code PENELOPE, where was the main structures of a simulated eukaryote cell. To simulate irradiation on cellular structures was used the emission spectrum of main radionuclide clinical use in nuclear medicine service. The material containing gold nanoparticles was modeled according the stoichiometric proportions found in the literature. The results obtained, present for the simulated energies to smaller bodies than 2,0μm, no substantial response to the use of nanoparticles in the reinforcement of locally absorbed dose. Is observed a small decrease in locally dose absorbed due to emission of charged particles, it is believed that causes an increase in the emission secondary range to be placed outside the study body. But this effect is small when comparing to the increase of energy absorbed due to interaction with the bodies containing nanoparticles, so demonstrating an increase in the locally dose absorbed. Being observed that there is an increase in dose absorbed locally due to the use of nanoparticles. For protocols based on the principle of target radionuclide therapy, the imaging of the treaty sit will be affected in their statistical accuracy, since the gamma radiation will be attenuated by the nanoparticles present in the material. Being necessary to know if this increase in the locally absorbed dose has greater importance in the treatment protocol than the image of the absorption of the radioactive material in the target organ.

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

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

Los enunciados destacaron la falta de operadores clínicos para lidar con ese fenómeno. Ese estudio concluyó que el desempleo es una temática de la Clínica Psicológica contemporánea, y que hay una necesidad de producirse operadores que den cuenta, en la clínica, de fenómenos contemporáneos que están emergiendo, como el desempleo, y que más estudios son necesarios acercándose a esta temática.This paper aims at understanding the practices of Clinical Psychology towards psychological suffering caused by contemporary unemployment. To this end, eight psychologists from Porto Alegre outskirts were interviewed. They were asked about their understanding of issues regarding work and unemployment and consequences to patients' subjectivity, intervention practices they used and the relationship of these interventions to theories and possible contributions of psychology towards the phenomenon under scrutiny. Content analysis was used to study the data collected during the interviews.Psychologists' utterances have been divided in four groups based on the following categories: work, unemployment, interventions towards unemployment and psychology's contributions to unemployment. The author concludes that clinical psychology needs to prepare professionals who are able to deal, in their clinical practices, with ever emerging contemporary phenomena such as unemployment. It is also highlighted that more investigations on this area of study are necessary.

    In our environment we do ignore the clinical and para clinical characteristics from patients who come to a thoracic pain unit and more so with the new definition of acute myocardial infarction (Amid). 398 patients admitted to a thoracic pain unit were prospectively evaluated as to the pain characteristics, its risk factors, clinical examination findings, electrocardiographic findings and the troponin a T behaviour. 29.4% of the patients had a diagnosis of Amid, 29.9% of unstable angina and 40.7% of non-ischemic thoracic pain. retrosternal pain, irradiation to the neck, presence of diaphoresis, nausea or vomit are related with a higher probability to the diagnosis of Amid. Male sex and the presence of risk factors such as diabetes or dislipidemia increase the probability of the diagnosis. In the electrocardiogram, only the presence of a lesion, especially subepicardical favors the diagnosis. Unstable angina and in general acute coronary syndrome have a similar although not equal clinical behavior.

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

    In the search for an isotope that will be ''ideal'' for scanning, Tc{sup 99m} appears to offer many advantages. This substance emits a clean 140-keV {gamma}-ray (9% converted) with no particle radiation, has a 6-h physical half-life, and is readily available at reasonable cost as the daughter of 2.7-d Mo{sup 99}, from which it is readily separated on an alumina column. In its usual form (Tc{sup 99m}O{sub 4}{sup -}) it is distributed in the body in a manner very similar to CIO{sub 4}{sup -} and I{sup -}, being rapidly distributed in the extracellular space and specifically trapped by the thyroid, stomach and salivary glands. Excretion data indicate a biological half-life of about 2 d. Thyroid scans of a superior quality, with an estimated radiation dosage of 100 mrad to the gland and 5 mrad total-body radiation, may be made between one-half and one hour after a 1-mc dose of this material - a very great improvement over I{sup 131}. TcO{sub 4} does not cross the blood-brain barrier freely, so that spectacular brain scans have been obtained with 2 to 5 min scanning time by making use of the high count-rate available from 5 to 10-mc doses of Tc{sup 99m}. As the pentavalent thiocyanate dissolved in fat emulsion, Tc{sup 99m} localizes in the liver to a large extent; the high count-rate available again permits rapid scans of this gland with improved resolution. It is anticipated that further gains with this isotope may be made possible by the use of probes of increased efficiency and by further manipulation of biological and chemical parameters. (author) [French] Dans la recherche du radioisotope 'ideal' pour la gammagraphie, {sup 99m}Tc- semble offrir de nombreux avantages. C'est un emetteur gamma pur de 140 keV (converti a 9%, sans rayonnement particulaire, ayant une periode de 6 h; on peut l'obtenir facilement et a peu de frais comme produit de filiation de {sup 99}Mo, qui a une periode de 67 h, dont on le separe aisement sur une colonne d'alumine. Sous sa forme habituelle ({sup 99m}TcO{sub 4}{sup -}), il se repartit dans le corps d'une facon tres semblable a CIO{sub 4}{sup -} et I{sup -}, c'est-a-dire qu'il est rapidement disperse dans l'espace extra-cellulaire et accumule selectivement par la thyroiede, l'estomac et les glandes salivaires. Les donnees fournies par les excreta indiquent que la periode biologique est d'environ deux jours. On peut faire d'excellents scintigrammes de la thyroiede; avec une irradiation evaluee a 100 mrad pour la thyroiede, et a 5 mrad pour l'ensemble du corps, une demi-heure a une heure apres administration de 1 mc de {sup 99m}TcO{sub 4}{sup -}, ce qui represente un tres grand progres par rapport a l'utilisation de {sup 131}I. TcO{sub 4} ne traverse pas librement la barriere sang-cerveau, de sorte que l'on a obtenu des scintigrammes spectaculaires du cerveau avec un temps de balayage de 2 a 5 min grace au taux de comptage eleve fourni par des doses de 5 a 10 me de 99mTc. Comme le thiocyanate pentavalent se dissout dans une emulsion de corps gras, {sup 99m}TcO{sub 4}{sup -} se localise en grande partie dans le foie; la aussi, le taux de comptage eleve permet des explorations rapides avec une meilleure resolution. On espere qu'il sera possible de faite de nouveaux progres avec ce radioisotope grace a l'utilisation de sondes plus efficaces et a une manipulation plus poussee des parametres biologiques et chimiques. (author) [Spanish] El {sup 99m}Tc es uno de los isotopos que mas ventajas ofrecen para la exploracion cen- telleografica. Emite rayos gamma limpios de 140 keV (9% de conversion) sin radiacion corpuscular, tiene un periodo fisico de 6 h y puede obtenerse facilmente a un precio razonalbe como descendiente del {sup 99}Mo, (periodo: 2,7 d) del que se separa sin dificultad en una columna de alumina. En su forma usual ({sup 99m}TcO{sub 4}{sup -}) se distribuye por el cuerpo de manera muy parecida al CIO{sub 4}{sup -} y al I{sup -}, penetra rapidamente en el espacio extra- celular y es captado selectivamente por la tiroides, el estomago y las glandulas salivales. Los datos facilitados por la excrecion indican que su periodo biologico es de unos 2 d. Con una dosis de irradiacion calculada en 100 mrad para la glandula y en 5 mrad para el cuerpo entero, se pueden efectuar exploraciones tiroideas de muy buena calidad entre meedia hora y una hora despues de administrar 1 me de esta sustancia lo que representa una gran ventaja sobre el {sup 131}I. El TcO{sub 4} no atraviesa libremente la barrera hematoencefalica, lo que ha permitido obtener excelentes imagenes del cerebro con un tiempo de exploracion de 2 a 5 min aprovechando el elevado fndice de recuento correspondiente a dosis de 5 a 10 me de {sup 99m}Tc. Como el tiocianap pentavalente se disuelve en una emulsion de grasa, gran parte del {sup 99m}Tc se localiza en el higado; en este caso el elevado fndice de recuento permite tambien proceder a una rapida exploracion de esta glandula con un'mayor poder de resolucion. Es muy probable que este tipo de mejores resultados aun utilizando sondas mas eficaces y adaptando los parametros biologicos y quimicos a condiciones optimas.

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

(author) [Spanish] La exploracion mediante radioisotopos permite localizar sin traumatismo distintos tipos de tumores humanos. Para lograr una representation visual satisfactoria, el detector debe poder resolver pequenas diferencias en la concentracion de los isotopos existentes entre los tejidos enfocados y los circundantes, y presentar estos datos en forma facilmente interpretable. Ademas, debe poseer la flexibilidad suficiente para poder adaptarse a los distintos grados de actividad y a las diferencias considerables en las razones de tejidos enfocados a circundantes, que suelen encontrarse en la practica medica. Dado que en la mayor parte de los casos, la exploracion por isotopos representa un metodo de seleccion diagnostica, la eficiencia global del recuento debe ser alta, a fin de que se reduzcan al minimo posible las dosis de radiacion aplicadas.

    Full Text Available Resumen Los medios audiovisuales son imprescindibles para reforzar la información del paciente. El objetivo del trabajo es describir la utilidad del uso de presentaciones educativas para los pacientes en hemodiálisis y los medios audiovisuales disponibles en la unidad. Se elaboraron tres presentaciones educativas en Microsoft Office Power Point y se pasaron una serie de cuestionarios con 13 preguntas que hacían referencia a aspectos fundamentales del cuidado tratados en las presentaciones, antes y después de éstas. Se realizó un análisis estadístico descriptivo con la distribución de frecuencias y porcentajes de las variables categóricas y con la media y la desviación típica de las variables cuantitativas. Para comprobar los resultados de las respuestas antes y después de las presentaciones/micropíldoras se ha utilizado la prueba de McNemar para dos muestras relacionadas con un nivel de significación estadística de p<0,05. El estudio consta de 45 pacientes, 73,3% varones con una edad media de 63,82 años. Se encontraron resultados estadísticamente significativos con p=0,031 y p=0,004, referentes a cuestiones sobre la desinfección de la fístula y el aporte proteico. El presente estudio ha servido para demostrar que la herramienta ha abierto nuevas posibilidades de formación a los pacientes.

    Full Text Available Though Free Radicals is one of the most frequently explored scientific subjects in mass communication media, the topic is absent of many Biochemistry introductory courses, especially those in which the students do not have a good chemical background. To overcome this contradictory situation we have developed a software treating this topic in a very simple way. The software is divided in four sections: (1 definition and description of free radicals, (2 production pathways, (3 mechanism of action and (4 enzymatic and non enzymatic protection. The instructional capacity of the software has been both qualitative and quantitatively evaluated through its application in undergraduate courses.

    Science.gov (United States)

    Costa Diaz, Agnes

    El estudio que se presenta es de caracter cualitativo, un estudio multicasos donde se estudia la estructura logica utilizada por cuatro (4) profesores universitarios que ensenan el curso introductorio de quimica, en la planificacion, presentacion y evaluacion del tema sobre el comportamiento de los gases. Se utilizaron varias fuentes de informacion como: cuestionarios de profesores y estudiantes, entrevistas, grabaciones videomagnetofonicas, materiales didacticos y una prueba conceptual, entre otros. La informacion recopilada fue analizada de acuerdo al orden logico del contenido presentado, el estilo de ensenanza del profesor, las tecnicas y estrategias utilizadas para el desarrollo de destrezas de pensamiento, el ambiente fisico en el salon de clase y los instrumentos de evaluacion y avaluo. El estudio demuestra que lo que los profesores piensan y planifican para hacer sus presentaciones no necesariamente es lo que ocurre en el salon de clases. El desarrollo de destrezas de pensamiento, que constituye una prioridad de los profesores, no se elaboran efectivamente. El uso de las estrategias de resolucion de problemas numericos predomino. La participacion del estudiante en el salon de clases fue limitada y no se logro demostrar el desarrollo de las destrezas de pensamiento deseadas. Aunque los profesores tienen su propio estilo de ensenanza, el orden logico del contenido presentado en clase fue el mismo o siguio muy de cerca el orden establecido por el libro de texto. Los profesores utilizaron preferentemente la tiza y la pizarra para sus presentaciones y la dinamica en el salon de clases fue esencialmente tradicional. Los profesores hicieron su presentacion y los estudiantes copiaron pasivamente la informacion. Las evaluaciones de los estudiantes fueron esencialmente, pruebas escritas de seleccion multiple de acuerdo con el estilo en que se les enseno. El avaluo fue casi inexistente. La prueba conceptual administrada revela un aprendizaje pobre en los conceptos mas

    Trascendiendo las diversas presentaciones posibles del autismo, ya la psiquiatría clásica recortaba rasgos constantes, invariantes que se desplegaban en todos los casos. Estos fenómenos en cuestión fueron considerados desde la fundación del cuadro clínico por Leo Kanner en 1943, como gravísimos trastornos.

    Full Text Available In questo articolo si prende in considerazione l’evoluzione teoretica della psicoanalisi, passando dal modello freudiano monadico ad un approccio di matrice relazionale.  Altresì  viene evidenziato il contributo della psicologia clinica come elemento costitutivo della psicoterapia psicoanalitica, come espressività del continuum psicologia clinica-psicoterapia. Tutto ciò rappresenta, inoltre, la conditio sine qua non per il cambiamento terapeutico. Se ne evidenziano, infatti gli elementi caratteristici per una buona riuscita del processo terapeutico. L’Autore inoltre, mette in rilievo il ruolo della psicocorporeità nel trattamento psicoanalitico, sia come comunicazione del ‘non verbale’ sia come costrutto epistemologico di un nuovo apporto alla scienza psicoanalitica.

    2010-06-01

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

L'analyse des scintigrammes du cerveau presente des difficultes lorsque le taux de comptage pour la zone suspecte est a peine plus eleve que pour les zones avoisinantes. On a etabli un schema 'normal' du taux de comptage pour le crane en divisant les scintigrammes en regions a peu pres equivalentes du point de vue anatomique d'un patient a l'autre, et en comptant les traces scintigraphiques dans chaque region. On peut comparer tout scintigramme anormal a ce schema. Une telle analyse est faite au mieux avec un ordinateur. L'utilisation de methodes d'etablissement continu des valeurs moyennes peut egalement presenter un interet pour l'amelioration de la visualisation des anomalies au voisinage des limites de la detection.

This ecologic and economic problem requires alternative uses to be found for fruit. The aim of this study was to use surplus fruit to produce vinegar by traditional methods (alcoholic fermentation and acetification from persimmon and strawberry. The process was performed with naturally occurring microorganisms and compared with inoculated commercial wine yeast for alcoholic fermentation. Alcoholic fermentation proceeded faster when inoculated due to the length of the lag phases observed in spontaneous fermentations. The alcoholic fermentations of strawberry mash were faster than those of persimmon mash. In contrast, acetifications were much faster in persimmon (30 days than in strawberry (70 days, in the latter some acetifications were not finished. From the technologic point of view, to produce persimmon and strawberry wine and vinegar, it is better to avoid fruit pressing and perform the process with fruit mash. Inoculation is recommended for persimmon and is necessary for strawberry.Keywords: wine, vinegar, fruit seasonings, acetic acid bacteria

    Bromine (Br) is one of the most abundant trace elements in the biosphere, in the human body is present in blood (as bromide), lungs, liver and hair. There is no evidence in humans of bromide concentration in any particular organ that might indicate a specific physiological function and not enough information is available on bromine metabolism but, some studies report its use by eosinophilic leukocytes for immune defense and electrolytic balance. In this study the Br levels were determined in Brazilian amateur athlete's blood that performing physical exercise at (Laboratorio de Bioquimica do Exercicio (LABEX/UNICAMP-Brazil). The samples were collected from twenty six male athletes, ranging from 18 to 26 years old, at rest. The blood samples were irradiated in the nuclear reactor (IEA-R1, 3-4.5MW, pool type) at IPEN/Sao Paulo - Brazil and were analyzed using Neutron Activation Analyses (NAA) technique. These results were compared with the control group (subjects of same age but not involved with physical activities). The range established at rest for amateur runner (0.0040 - 0.0096 gL -1 ) when compared with control group (0.0074 - 0.0306 gL -1 ) suggests that there is a dependency of these limits in the function of the adopted physical training.

    Intense physical training is known to be associated with increased mineral losses through sweating (during the exercise) and also through urine (after the exercise). Nowadays physical training is recognized for adapting or damaging the muscles, depending on the intensity and duration of the effort, provoking detectable metabolic alterations in blood, mainly in the content of some ions. In this study Br, Ca, Cl, K, Mg, Na and S levels were investigated in blood of Brazilian athletes that were submitted to constant physical exercise, at Laboratorio de Bioquimica do Exercicio (LABEX/UNICAMP) using Neutron Activation Analyses technique (NAA). The blood samples were collected from male amateurs and elite athletes, ranging from 18 to 36 years old. The blood samples were irradiated in the nuclear reactor (IEA-R1, 3-4.5 MW, pool type) at IPEN/Sao Paulo-Brazil. The concentrations data were compared with the control group (subjects of same gender and age but not involved with physical activities). These data can be useful for evaluating the performance of endurance athletes during the period of competition preparation as well as to propose new evaluation of protocols not yet reported.

    Sodium (Na), chlorine (Cl) and potassium (K) are widely distributed in the body and are the mainly of body fluids electrolytes. K is the major intracellular ion. Na and Cl are the major extracellular ions. Therefore, Na and Cl can be regarded as the most important osmotically active electrolytes. The concentrations of these ions in body fluids are very tightly controlled. These electrolytes play central roles in electrolytic balances and current, in osmotic control, in the transport of organic metabolites by cells, and stabilization of poly electrolytes in cells. In this study Na, Cl and K levels were investigated in blood of athletes submitted to physical exercise at Laboratorio de Bioquimica do Exercicio (LABEX/UNICAMP - Brazil) using Neutron Activation Analyses (NAA) technique. The blood samples were collected from six male athletes, ranging from 18 to 26 years old, before and after the physical training. These results were compared with the rest condition (before start the physical exercise), as well as with the control group (subjects of same age but not involved with physical activities), for checking the performance of the athletes during and after the exercise. The nuclear procedure adopted as NAA, it can be an alternative procedure to perform biochemistry analyses in blood, mainly when the biological material is scarce. (author)

    In sports medicine, sulfur plays an important role and its deficiency can cause muscle injury affecting the performance of the athletes. However, its evaluation is unusual in conventional clinical practice. In this study the sulfur levels were determined in Brazilian amateur athlete's blood using Neutron Activation Analyses (NAA) technique. Twenty six male amateur runners, age 18 to 36 years, participated of this study. The athletes had a balanced diet, without multivitamin/mineral supplements. The blood collection was performed at LABEX (Laboratoriode Bioquimica do Exercicio, UNICAMP-SP) and the samples were irradiated for 300 seconds in a pneumatic station in the nuclear reactor (IEA-R1, 3-4.5MW, pool type) at IPEN/CNEN-SP. The results were compared with the control group (subjects of same age but not involved with physical activities) and showed that the sulfur concentration was 44% higher in amateurs athletes than control group. These data can be considered for preparation of balanced diet, as well as contributing for proposing new protocols of clinical evaluation. (paper)

    New densitometer installation requires cross-calibration for accurate longitudinal assessment. When replacing a unit with the same model, the International Society for Clinical Densitometry recommends cross-calibrating by scanning phantoms 10 times on each instrument and states that spine bone mineral density (BMD) should be within 1%, whereas total body lean, fat, and %fat mass should be within 2% of the prior instrument. However, there is limited validation that these recommendations provide adequate total body cross-calibration. Here, we report a total body cross-calibration experience with phantoms and humans. Cross-calibration between an existing and new Lunar iDXA was performed using 3 encapsulated spine phantoms (GE [GE Lunar, Madison, WI], BioClinica [BioClinica Inc, Princeton, NJ], and Hologic [Hologic Inc, Bedford, MA]), 1 total body composition phantom (BioClinica), and 30 human volunteers. Thirty scans of each phantom and a total body scan of human volunteers were obtained on each instrument. All spine phantom BMD means were similar (within 1%; g/cm2 bias) between the existing and new dual-energy X-ray absorptiometry unit. The BioClinica body composition phantom (BBCP) BMD and bone mineral content (BMC) values were within 2% with biases of 0.005 g/cm2 and -3.4 g. However, lean and fat mass and %fat differed by 4.6%-7.7% with biases of +463 g, -496 g, and -2.8%, respectively. In vivo comparison supported BBCP data; BMD and BMC were within ∼2%, but lean and fat mass and %fat differed from 1.6% to 4.9% with biases of +833 g, -860 g, and -1.1%. As all body composition comparisons exceeded the recommended 2%, the new densitometer was recalibrated. After recalibration, in vivo bias was lower (g, respectively. Similarly, BBCP lean and fat agreement improved. In conclusion, the BBCP behaves similarly, but not identical, to human in vivo measurements for densitometer cross-calibration. Spine phantoms, despite good BMD and BMC agreement, did not detect

A recent cognitive–affective model suggests an interaction between drug motivation and affective symptoms. The aim of this multicenter study was to evaluate the psychological changes in subjects undergoing a residential rehabilitation program specifically designed for alcohol addiction, and to identify at discharge patients with greater affective symptoms and therefore more at risk of relapse.Materials and methods: The sample included 560 subjects (mean age 46.91±10.2 years who completed 28-day rehabilitation programs for alcohol addiction, following a tailored routine characterized by short duration and high intensity of medical and psychotherapeutic treatment. The psychological clinical profiles of anxiety, depression, psychological distress, psychological well-being, and self-perception of a positive change were assessed using the Cognitive Behavioral Assessment – Outcome Evaluation questionnaire at the beginning and at the end of the program. The changes in the psychological variables of the questionnaire were identified and considered as outcome

    The only hypnotizability scale that has been translated and validated for the Puerto Rican population is the Barber Suggestibility Scale (BSS). In this article, the Stanford Hypnotic Clinical Scale (SHCS) was translated and validated for this population. The translated SHCS ("Escala Stanford de Hipnosis Clinica" [ESHC]) was administered individually to 100 Puerto Rican college students. There were no significant differences found between the norms of the original SHCS samples and the Spanish version of the SHCS. Both samples showed similar distributions. The Spanish version's internal reliability as well as the item discrimination index were adequate. The authors conclude that the ESHC is an adequate instrument to measure hypnotizability in the Puerto Rican population.

Si è così costruita una sorta di mitologia eterosessuale di quel triangolo, lasciando aperto il lato che collega il figlio al padre. Si tenta qui di saldare la parte mancante, a partire dalla narrazione del mito e arrivando alle dinamiche psichiche che caratterizzano le famiglie contemporanee, con particolare attenzione alla clinica dell’adolescenza contemporanea.

El uso del examen de orina completa y de urocultivo debe ser racional. La bacteriuria asintomática no debe ser buscada ni tratada, en parte porque esto favorece el desarrollo de bacterias resistentes a antibióticos. Distintos cuadros clínicos requieren de distintas duraciones de terapia antibiótica, y tanto el exceso de días de tratamiento como su falta deben evitarse. Se requiere investigación en la búsqueda de estrategias más efectivas para prevenir las ITU recurrentes y en el desarrollo de nuevos antibióticos orales para las ITU resistentes.

La élite "criolla" veía sus países retrasarse cada vez más dentro de un mundo en muy rápida evolución, en el cual prevalecían los valores culturales de Europa occidental. Este atraso parecía explicarse por la presencia cultural, social y étnica mayoritariamente no europea.

    Full Text Available Introducción: Cualquier practicante de ciencia está frecuentemente expuesto al discurso público (DP: conferencias, congresos, simposios, seminarios, entrevistas, talleres, etc. Por ello, es imprescindible saber comunicar las ideas con claridad y contundencia en una presentación oral. Usualmente, profesionistas y estudiantes enfrentan estas situaciones utilizando el sentido común, asumiendo que las habilidades para dar una buena presentación oral se adquieren con la práctica. Sin embargo es común ver profesionistas que a pesar de tener años de experiencia en foros de DP, siguen haciendo presentaciones orales muy deficientes. La hipótesis de este trabajo es que la práctica, por sí misma, puede no ser la única forma de adquirir dichas habilidades, sino que es posible mejorar el desempeño en las presentaciones orales mediante la enseñanza de las bases científicas del DP. Método: Tras una presentación oral individual de 10 minutos, se aplicó una prueba de desempeño en el DP (prueba Rapee a un grupo de 15 alumnos de posgrado en ciencias marinas antes y después de tomar un curso de DP. En el curso se enseñó la ciencia que existe detrás del DP, los protocolos del DP en la ciencia y la aplicación de los principios del diseño gráfico en el material de apoyo visual de una presentación oral. Los resultados generales de la prueba Rapee aplicada antes y después del curso se compararon mediante un análisis de diferencias de medias de muestras independientes (p valor de 0.05 y los resultados particulares mediante diagramas de contornos que representan la distribución de las calificaciones en función de las evaluaciones. Resultados: la calificación promedio del grupo en la prueba Rapee antes de que los alumnos tomaran el curso, se situó en un nivel de bajo desempeño (48 puntos de 68. Después de haber cursado la materia, este promedio se incrementó significativamente (de 48 a 57 puntos. La mejoría fue más evidente en las

    Full Text Available De um grupo de 66 pacientes com sindrome de Lennox Gastaut, 15 apresentaram as primeiras manifestações clinicas após os 6 anos de idade. Desses, 12 foram acompanhados durante o período médio de 2 anos e 6 meses, com avaliações neurológicas a intervalos de cerca de 2 meses. A revisão das publicações pertinentes permitiu estabelecer que em 20% das casuisticas apreciadas a sindrome de Lennox-Gastaut se inicia após o 6° ano de vida. As avaliações clinicas permitiram verificar que nosos pacientes apresentaram incidência de lesões neurológicas graves precedendo a instalação da síndrome por vários anos. As avaliações psicométricas evidenciaram intenso comprometimento do nível intelectual em contraste com os dados da literatura sobre a síndrome de Lennox-Gastaut de início tardio.

    Collaboration is essential for biomedical research. The Carlos III Health Institute (the Spanish national public organization responsible for promoting biomedical research) has encouraged scientific collaboration by promoting Thematic Networks and Cooperative Research Centres. Scientific collaboration in Enfermedades Infecciosas y Microbiología Clinica journal is investigated. Papers published in Enfermedades Infecciosas y Microbiología Clinica in the period 2002-2007 have been identified. Bibliometrics and Social Network Analysis methods have been carried out in order to quantify and characterise scientific collaboration and research areas. A total of 805 papers generated by 2,289 authors and 326 institutions have been analysed. There were 36 research groups involving 138 authors identified. The Collaboration Index for articles was 5.5. Institutional collaboration was determined in 75% of articles. The collaboration between departments or units of the same institution prevails (43%), followed by intra-regional domestic collaboration (41%) and inter-regional domestic collaboration (14%). Hospital centres were the main institutional sector responsible of research (88% of papers), with 68% of articles cited. Sida/VIH (AIDS/HIV) is the main research area (n=114), followed by Staphylococcal Infections (n=33). Notable collaboration and citation rates have been observed.

    A very important increase in the costs of the edition of scientific journals has taken place in Venezuela, due to difficulties in obtaining imported free acid paper and other materials used for handling documents. Like other journals, Investigaci6n Clinica has been considering switching completely to a digital publication format; however there are several reasons that prevent us to doing it at this time: the journal is distributed in printed form to many national institutions, which do not have immediate access to digital information. In addition, there exists a commitment of shipment of printed issues for some international indices and in exchange with other national and foreign journals, whose printed format we receive. Another important aspect is that our University maintains a weak technological platform that makes difficult the immediacy required for the interchange with authors and consulted referees of received papers; and there is a latent danger of limitations in the use of digital technologies, due to current national politic problems. Consequently, we need to continue with the printed format, but must reduce the amount of printed issues, so as not to limit the number of papers published in each edition. Nevertheless, there is an ever increasing number of contributions from foreign researches and Investigaci6n Clinica has been recently included in two new international indices, the SEIIC from Argentina and the Infobase Index from India, reasons that obligate us to maintain our levels of excellence and commitment to our authors and readers.

    Electronic Patient Reported Outcomes (ePRO) gathered using telemonitoring solutions might be a valuable source of information in rare cancer research. The objective of this paper was to develop a concept and implement a prototype for introducing ePRO into the existing neuroblastoma research network by applying Near Field Communication and mobile technology. For physicians, an application was developed for registering patients within the research network and providing patients with an ID card and a PIN for authentication when transmitting telemonitoring data to the Electronic Data Capture system OpenClinica. For patients, a previously developed telemonitoring system was extended by a Simple Object Access Protocol (SOAP) interface for transmitting nine different health parameters and toxicities. The concept was fully implemented on the front-end side. The developed application for physicians was prototypically implemented and the mobile application of the telemonitoring system was successfully connected to OpenClinica. Future work will focus on the implementation of the back-end features.

    Full Text Available La función principal de las neuronas del ganglio de la raiz dorsal (GRD es transmitir la información sensorial desde la periferia hasta el sistema nervioso central. Dos clases de células están presentes en el ganglio: las células no neuronales y las neuronales. La heterogeneidad morfológica, fisiológica y bioquimica de la población neuronal permite diferenciarla en subpoblaciones. Morfológicarnente, se distinguen tres tipos neuronales (A, B y C segun el tamaño y las caracteristicas ultraestructurales. Fisiológicamente, hay una relación directa entre el tamaño, el diámetro de las fibras nerviosas y la velocidad con que conducen el impulso nervioso. Finalmente, el uso de marcadores (neuropéptidos, enzimas, receptores, etc. permite realizar una clasificación bioquímica, que es la más utilizada para estudiar la función neuronal.

    A nine-month-old Labrador retriever was referred to the Clinica Veterinaria Privata San Marco because of frequent headshaking and downward turning of the right ear. Clinical examination revealed that there was no external acoustic meatus in the right ear. Computed tomography confirmed that the vertical part of the right auditory canal ended blindly, providing a diagnosis of external auditory canal atresia. Cytological examination and culture of fluid from the canal and the bulla revealed only aseptic cerumen; for this reason, it was assumed that the dog was probably affected by a congenital developmental deformity of the external auditory canal. Reconstructive surgery was performed using a "pull-through" technique. Four months after surgery the cosmetic and functional results were satisfactory.

    Currently, there are around 150,000 HIV-infected patients in Spain. This number, together with the fact that this disease is now a chronic condition since the introduction of antiretroviral therapy, has generated an increasing demand on the clinical microbiology laboratories in our hospitals. This increase has occurred not only in the diagnosis and treatment of opportunistic diseases, but also in tests related to the diagnosis and therapeutic management of HIV infection. To meet this demand, the Sociedad de Enfermedades Infecciosas y Microbiología Clinica (Spanish Society of Infectious Diseases and Clinical Microbiology) has updated its standard Procedure for the microbiological diagnosis of HIV infection. The main advances related to serological diagnosis, plasma viral load, and detection of resistance to antiretroviral drugs are reviewed in this version of the Procedure.

    The experience of the Radiotherapy Service, Clinica Puerta de Hierro, Madrid (Spain), in the treatment of intracranial tumors with risk of neural axis dissemination is analyzed. In 15 years (1964 to 1979) 415 primary central nervous system tumors were studied and treated; 67 corresponded to tumors with risk of meningeal dissemination. Clinical dissemination in cerebrospinal fluid was proven in 14 patients. The actuarial survival of 10 years for patients with neural axis dissemination, without prophylactic treatment to the neuroaxis, is 14% with an average survival of 10.5 months. In approximately 20% of meduloblastomas, ependymal and pineal region tumors, meningeal metastases at some distance from the primary tumor can take place. Patients at risk with these types of neoplasia must be identified, ad an adequate radical therapeutic focus devised, not only for the primary tumor, but also for the risk of dissemination

    The research on stress, mobbing, and substance dependence in workers employed in the building of the great infrastructures is part of the project Euridice-Ten. The 75% of the workers employed took part in the research through an anonymous and structured questionnaire. The Clinica del Lavoro of the University of Milan elaborated the data. They point out a high risk of stress, a low level of control, a marked risk of mobbing, a high chronic fatigue in the most exhausting jobs, sleep disorders, problems in the social life as well as at home, in nourishment and at work. Many workers drink too much alcohol and the 9% of the workers know workers who use cocaine.

    There is a rising interest for clinical cases in medicine. Actually, they don't necessarily conflict with the evidence-based medicine approach; rather, as several authors made clear, EBM-oriented case reports and clinical trials could be complementary. Cases and case series could even represent the first line of evidence and they are extremely valuable in discovering new pathologies and monitoring unexpected drug effects. They also play a relevant role in continuing medical education. The new section of Recenti Progressi in Medicina is edited by a prominent Italian research Institute (Istituto di Fisiologia Clinica, CNR). It focuses on a single case, guiding the physicians' decision-making from differential diagnosis to the treatment options.

    Clinical biochemistry in Spain was first established in 1978 as an independent specialty. It is one of several clinical laboratory sciences specialties, together with haematology, microbiology, immunology and general laboratory (Clinical analysis, análisis clinicos). Graduates in Medicine, Pharmacy, Chemistry and Biological Sciences can enter post-graduate training in Clinical Chemistry after a nation-wide examination. Training in an accredited Clinical Chemistry department is 4 years. A national committee for medical and pharmacist specialties advises the government on the number of trainees, program and educational units accreditation criteria. Technical staff includes nurses and specifically trained technologists. Accreditation of laboratories is developed at different regional levels. The Spanish Society for Clinical Biochemistry and Molecular Pathology (SECQ), the national representative in the IFCC, has 1600 members, currently publishes a scientific journal (Química Clinica) and a newsletter. It organizes a continuous education program, a quality control program and an annual Congress.

    @@ The diagnosis of bipolar rather than unipolar depression is currently a clinicaI diagnosis which cannot be validated by specific biological measures,such as laboratory tests.Certainly the characteristics of bipolar depression frequently differ from unipolar major depression in that patients with bipolar depression generally have an earlier age of onset and more frequent episodes than individuals with unipolar major depression[1]Some,but not all,studies support an increase in suicidal behaviors among bipolar as compared with unipolar major depression[2],and"atypical features"such as hypersomnia and hyperphagia also may be found more frequently among individuals with bipolar depression.Furthermore family histories of subjects with bipolar disorders more frequently reveal relatives with bipolar disorder.In contrast,relatives of patients with unipolar depression's family history generally reflects major depression but not bipolar disorder[3].

    2010-01-01

    Before implementing a treatment technique, the characteristics of the beam under irradiation conditions must be well acknowledged and studied. Each one of the parameters used to calculate the dose has to be measured and validated before its utilization in clinical practice. This is particularly necessary when dealing with special techniques. In this work, all necessary parameters and measurements are described for the total body irradiation implementation in facilities designed for conventional treatments that make use of unconventional geometries to generate desired enlarged field sizes. Furthermore, this work presents commissioning data of this modality at Hospital das Clinicas of Sao Paulo using comparison of three detectors types for measurements of entrance dose during total body irradiation treatment.

    This paper presents the results of in vivo dosimetry with p-type semiconductors diodes, EDP-15 (Scanditronix Wellhoefer) of two patients who underwent total body irradiation treatments, at Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto University of Sao Paulo (HCFMRP-USP). The diodes were well calibrated and the calibration factors were determined with the aid of a reference ionization chamber (FC065, IBA dosimetry, sensitive volume of 0.65 cm{sup 3}).The calibration was performed in a Total Body Irradiation (TBI) setup, using solid water phantoms. Different lateral thicknesses from one patient were simulated and then the calibration factors were determined by means of maximum depth dose readings (half of the lateral thickness). The response difference between diode readings and the prescribed dose for both treatments was below 4%. This difference is in agreement as recommended by International Commission on Radiation Units (ICRU), which is {+-}5%. (author)

    As delayed radiation damage after treatment of bronchial carcinoma and mamma carcinoma, fibroses occur as a reaction of the tissues. They have become a clinical-functional syndrome because of their uniform clinicaL-radiological symptomatology and pathophysiology. Pulmonary fibrosis as delayed radiation damage has a special importance with its two different radiation effects on connective tissue: a) on existing structures, b) delayed alterations of the connective tissue. As seen from experiments on lungs of men and rats, radiation-induced alterations can be measured by testing the different solubilities of the collagen types. In addition to the pathologically disordered collagen production, 9 weeks after the irradiation the radiation fibrosis leads to an isolated increase of insoluble collagen corresponding to the formation of metabolism-resistant fibrils.

    This is a qualitative, descriptive, exploratory, and interventionist research carried out with nine female lay caretakers of children undergoing oncologic treatment. The objectives were to present the multiple social roles performed by female lay caretakers of children with cancer and to discuss the caretaker's role in society. The study was carried out between March and April, 2007, at Hospital de Clinicas de Porto Alegre, Rio Grande do Sul, Brazil. The data collection was performed with the focal group technique. The results were examined through the analysis of thematic content, which evidenced the multiple social roles performed by women, the main group of caretakers in society, regardless of the context. Final considerations enhance a discussion in the educational, political and social levels about the redistribution of social roles, particularly family responsibility between men and women. The participation of the nursing staff can take place through the comprehension of those roles imposed by the context and facilitate family inclusion in the care relationship.

In particolare viene avanzata una lettura che connette i comportamenti e le relazioni lavorative quali esiti della difficoltà dei singoli nella mentalizzazione dei modelli ideologico-culturali che li determinano in un dato momento storico. Viene criticata una lettura, tendenzialmente presente in psicologia clinica e in psicologia del lavoro, in chiave riduttivamente individualistica, la quale attribuisce al singolo presunti deficit psichici ricercando le cause, e gli antecedenti delle condotte disadattive delle formazioni psicopatologiche, nella sola storia personale e individuale dei soggetti.

    Full Text Available Aim: To present a long term follow up clinical case in which a compromised anterior tooth was saved by a surgical extrusion procedure. Summary: Although different techniques have been suggested for clinical crown lengthening in the anterior zone, some of them have limitations in terms of aesthetics and procedural requirements. The current case report demonstrates how a simplified surgical extrusion procedure was successfully performed for saving a severely damaged anterior tooth; furthermore, it is possible to apply the technique described in this case using minimum and simple armamentarium like a scalpel, elevators, forceps and splinting flexible cord. Key-learning points: Saving severely compromised anterior teeth is possible by applying surgical extrusion techniques when crown-root ratio allows it. Risk of root resorption or ankylosis is minimum. Riassunto: Obiettivo: Presentare un caso clinico con controllo a 5 anni in cui un dente anteriore compromesso è stato recuperato con una procedura di estrusione chirurgica. Riassunto: Sebbene siano state suggerite diverse tecniche per l’allungamento della corona clinica nella zona anteriore, alcune di esse presentano limitazioni in termini di estetica e competenza nelle procedure. Il presente case report dimostra come una procedura di estrusione chirurgica semplificata sia stata eseguita con successo per salvare un dente anteriore gravemente danneggiato. Va sottolineato che la tecnica descritta in questo caso può essere portata a termine utilizzando un armamentario minimo e molto semplice come un bisturi, leve, pinze e uno splintaggio flessibile. Key learning points: E’ possibile salvare elementi dentari gravemente compromessi applicando tecniche di estrusione chirurgica quando il rapporto corona-radice lo consente. Il rischio di riassorbimento della radice o anchilosi è minimo. Keywords: Crown fracture, Crown lengthening, Surgical extrusion, Surgical repositioning, Biologic width, Parole

  1. Integration of a clinical trial database with a PACS

    International Nuclear Information System (INIS)

    Van Herk, M

    2014-01-01

    Many clinical trials use Electronic Case Report Forms (ECRF), e.g., from OpenClinica. Trial data is augmented if DICOM scans, dose cubes, etc. from the Picture Archiving and Communication System (PACS) are included for data mining. Unfortunately, there is as yet no structured way to collect DICOM objects in trial databases. In this paper, we obtain a tight integration of ECRF and PACS using open source software. Methods: DICOM identifiers for selected images/series/studies are stored in associated ECRF events (e.g., baseline) as follows: 1) JavaScript added to OpenClinica communicates using HTML with a gateway server inside the hospitals firewall; 2) On this gateway, an open source DICOM server runs scripts to query and select the data, returning anonymized identifiers; 3) The scripts then collects, anonymizes, zips and transmits selected data to a central trial server; 4) Here data is stored in a DICOM archive which allows authorized ECRF users to view and download the anonymous images associated with each event. Results: All integration scripts are open source. The PACS administrator configures the anonymization script and decides to use the gateway in passive (receiving) mode or in an active mode going out to the PACS to gather data. Our ECRF centric approach supports automatic data mining by iterating over the cases in the ECRF database, providing the identifiers to load images and the clinical data to correlate with image analysis results. Conclusions: Using open source software and web technology, a tight integration has been achieved between PACS and ECRF.

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

    Full Text Available Desde una visión interdisciplinaria, este trabajo busca reconocer actitudes populistas en la narrativa y el habla de Fernando Vallejo. Se observa cómo el autor y el gramático narrador de sus novelas y film (1994-2010, 2000 recurren de forma insistente y unívoca a la difusión de un pensamiento demoledor de la vieja institucionalidad, que funda la nación latinoamericana con estrategias comunicativas provocadoras, autoritarias, afectuosas y mesiánicas que, por lo general, tipifican el discurso populista. En la primera parte se discute el entronque ideológicopolítico de Vallejo con la tradición literaria latinoamericana. En la segunda parte se analiza la forma en la que discurren las estrategias comunicativas que se anotan. Algunas de sus novelas, ensayos y presentaciones públicas constituyen la materia de este trabajo. Al final, se destaca la genialidad del lenguaje vallejiano para articular una extraña forma de encantamiento social que carece de un estilo definido.

    We discuss the steady-state electronic transport in solid-state and molecular devices in the quantum regime. The decimation technique allows a comprehensive description of the electronic structure. Such a method is used, in conjunction with the generalizations of Landauer's tunneling formalism, to describe a wide range of transport regimes. We analyze mesoscopic and semiclassical metallic transport, the metal-insulator transition, and the resonant tunneling regime. The effects of decoherence on transport is discussed in terms of the D' Amato-Pastawski model. A brief presentation of the time dependent phenomena is also included.

    2014-06-01

    Full Text Available La normalización de la violencia en la vida cotidiana a la que alude el cuento de dos páginas del guatemalteco Carlos Paniagua (publicado en Informe de un suicidio en 1993, “El llanto de un niño”, es mostrada con irónica naturalidad desde la casi indiferencia del narrador. Las presentaciones y representaciones estéticas de la violencia en las literaturas latinas y centroamericanas han sido abordadas tradicionalmente por la crítica desde el vínculo entre la práctica escritural y la denuncia de la violencia política. Cabe mencionar el caso de la novela de la Violencia colombiana sobre la que hay cierto consenso al afirmar, como lo sugiere Paschen (1994, que la mayoría de estas novelas poseen un carácter testimonial y de denuncia, ya que tanto los acontecimientos como los personajes suelen tener un referente histórico verificable. Pero junto a estas novelas de “denuncia social”, explica Paschen, se publican otras que se dedican a la representación de la subjetividad de quienes participan o se ven afectados por la Violencia colombiana.

    1994-12-31

    The drying of products -meaning the extraction of water or excess humidity down to adequate levels for its conservation and final presentation- demands a large amount of energy, mainly from fuels of fossil origin. Nevertheless, from the standpoint of the energy efficiency, the burning of fuels at very high temperature for using them at a very low temperature, represents an astonishing energy waste, which can be clearly established by means of an energy and exergy balance of these drying installations. In this study the methodology for the energy analysis for industrial drying systems is presented and it is applied to different practical cases. The efficiency of the entire system is evaluated and the losses for each concept, in order to obtain the potential energy saving. [Espanol] El secado de productos, entendido como la extraccion de agua o humedad en exceso, hasta niveles adecuados para su conservacion o presentacion final, demanda una gran cantidad de energeticos, principalmente de origen fosil. No obstante, desde el punto de vista de la eficiencia energetica, el quemar combustible a muy alta temperatura para emplearlos a una muy baja, representa un dispendio energetico impresionante, lo cual puede ser claramente establecido mediante el balance energetico y exergetico de dichas instalaciones de secado. En el presente estudio se presenta la metodologia de analisis energetico de sistemas industriales de secado y se aplica a distintos casos practicos. Se evalua la eficiencia total del sistema y las perdidas por cada concepto con la finalidad de obtener los potenciales de ahorro de energia.

    Full Text Available En este trabajo vamos a abordar el tema del tiempo en las ciudades míticas en las obras Cien años de soledad de Gabriel García Márquez, Pedro Páramo de Juan Rulfo y El astillero de Juan Carlos Onetti. Vamos a investigar los problemas siguientes: las relaciones entre distintas presentaciones del tiempo (lineal o circular, la supresión de las diferencias entre pasado, presente y futuro y la analogía con el concepto de la eternidad en el mito, la memoria y el olvido, la ambigüedad entre la muerte y la vida que se basa en el concepto mítico de la muerte. Por ejemplo, en Macondo de García Márquez se entrelazan el tiempo lineal de la habitación de Melquíades con el tiempo cíclico de la ficción, en Comala de Juan Rulfo se borran las fronteras entre la vida y la muerte y existe un tiempo común para todos, en Santa María de Onetti se altera el orden del tiempo común con la estructura de narradores múltiples, etc.

    The Master in Space Science and Technology of the Basque Country University UPV/EHU in Bilbao (Spain) has been taught during 7 years (A. Sanchez-Lavega et al., Eur. J. of Eng. Education. 2014). Along the different courses, a series of practical observations and studies of planetary sciences have been conducted with Master students, using telescopes with diameters in the range 28-50 cm pertaining to the Aula EspaZio Gela Observatory (http://www.ehu.eus/aula-espazio/presentacion.html). Simple instrumentation (cameras and a spectrograph) have been employed to study planetary atmospheres (dynamics and cloud structure) and orbital mechanics using the Galilean satellites. Here we present a sample of these studies, which have lead to publications in refereed journals and have been presented at different meetings with the coauthoring of the students. Plans for the future include involving the master students in high-resolution observations of Solar System planets using a remote controlled 36 cm telescope at the Calar Alto observatory in Southern Spain (separated 1000 km from the teaching facilities in Bilbao).

    Miguel Farías Farías

    2013-04-01

    Full Text Available El principio y el efecto de redundancia parecieran ser un impedimento para el aprendizaje en campos diversos. Este trabajo da cuenta de una investigación que intenta probar si tal redundancia tiene también efectos negativos en el aprendizaje de expresiones idiomáticas en inglés como lengua extranjera. Dos grupos de estudiantes universitarios fueron expuestos a dos tipos de presentaciones multimodales: uno, a texto en pantalla, narración e imagen fija; y el otro a texto en pantalla y narración. Según el principio de redundancia, la presentación del primer grupo duplicaría la información y conllevaría a una sobrecarga cognitiva. Aunque los resultados indican que no hay mayor variación entre los dos grupos en cuanto a retención, en transferencia hay variaciones atribuibles a las características semánticas del vocabulario presentado.

    Full Text Available En la actualidad los procesos evaluativos han cobrado importancia, pues se requieren instrumentos objetivos que ofrezcan un medio para valorar las competencias logradas por el estudiantado, en determinado proceso de enseñanza-aprendizaje. Las rúbricas de evaluación ofrecen un mecanismo objetivo, que estandariza los indicadores a valorar, según el rendimiento mostrado por el estudiantado. Además, le permite al personal docente orientar y retroalimentar al alumnado, quienes también podrán utilizar el instrumento para autoevaluarse y prepararse de antemano, de acuerdo con las especificaciones descritas en la rúbrica. El objetivo del presente trabajo es elaborar una rúbrica de evaluación para el curso de Clínica de Exodoncia y Cirugía. Dicho instrumento se realizó considerando las opiniones del 40% del profesorado a cargo del curso, por medio de una entrevista semi-estructurada. Esta rúbrica ofrece una herramienta que estandariza el proceso de evaluación de las "presentaciones de caso" y permite que el equipo docente pueda retroalimentar al estudiantado y favorece la interacción docente-estudiante.

El orden temporal de dos eventos, cada uno de ellos presentado en un hemicampo visual diferente, puede ser juzgado correctamente por observadores típicos inclusive cuando la diferencia de tiempo entre las presentaciones sea muy pequeña. El presente trabajo analiza la influencia de un proceso endógeno sobre el juicio de orden temporal (JOT y nos muestra que la percepción del orden temporal está también afectada cuando los recursos atencionales disponibles son reducidos mediante un paradigma de parpadeo atencional (PA. A los participantes se les presentaron los siguientes estímulos: un primer estímulo visual (T1 en el centro de fijación y luego de un intervalo de tiempo variable (280 ó 1030 ms, un par de estímulos lateralizados (T2. Para la tarea dual con el intervalo de tiempo de 280 ms entre T1 y T2, la precisión en el JOT se deterioró, evidenciando un PA. Sin embargo, durante el PA en lugar de la asimetría favorable al lado izquierdo, aparece un significativo sesgo en contra de ese lado.

    Full Text Available El linfoma no Hodgkin primario de sistema nervioso central es una afección poco frecuente en la población pediátrica. No existen (o son pocas las recomendaciones o estudios clínicos que sean útiles para definir la mejor opción terapéutica. El objetivo de este trabajo es describir el caso de una niña con linfoma primario de sistema nervioso central, sin ninguna inmunodeficiencia asociada, y realizar de una revisión cualitativa de la literatura especializada sobre esta enfermedad en niños. Se ha postulado la posibilidad de cambios citogenéticos que pudieran explicar la heterogeneidad en el comportamiento de esta enfermedad pues se ha visto que es distinto al de otros linfomas en presentaciones habituales. La experiencia de tratamiento en niños con linfoma se basa en resultados de tratamientos obtenidos en pacientes adultos, con regímenes basados principalmente en antimetabolitos como metotrexato y citarabina. Aún es controvertida la utilidad de la radioterapia craneal, la cual sólo se recomienda en casos específicos.

    A developed methodology allows making a regional pacification based on the river's water quality and their guide levels for different uses. To get this methodology it was used an optimization model that allows obtaining the best combination of town and industrial liquid treatments of the region, which can make cheaper their construction and maintenance costs. The established regional stages of economical development, were simulated with the QUAL2E model, from this model was obtained the restriction coefficients of the optimization model. More over, this model allowed to prognosticate the behavior of the principal water quality components (dissolved and biochemical demand of oxygen, nitrogen, phosphorus and others) for different proposed stages. This methodology was applied over a section of Neuquen River (Argentina) which receives urban, industrial and farming effluents of three cities Centenario (Plant 1), Cinco Saltos (Plant 2) and Parque Industrial (Plant 3). From results, it can be affirmed that under present situation, there is not contamination hazard. However, under future scenarios, advanced and secondary treatment is required to assure meeting the quality standards, particularly when river discharge approach it annual minimum.

Los escenarios de desarrollo economico regional planteados se simularon con el modelo QUAL2E, de donde se obtuvieron los coeficientes de las restricciones del modelo de optimizacion. El modelo de simulacion permitio, ademas, pronosticar el comportamiento de los principales componentes de calidad del agua (oxigeno disuelto, demanda bioquimica de oxigeno

    The contributions of science and technology have covered the whole of human life, and relationships of coexistence are even found in the various disciplines of knowledge through legal forensics. Therefore, it is increasingly imperative that the law enforcement agents are interdisciplinary professionals, with knowledge beyond the legal knowledge to enable them make the most of the scientific knowledge in judicial proceedings. Among the natural sciences applied to right, forensic biochemistry has contributed an extremely relevant test for the investigation of various sexual offenses, much has been so, that the Organismo de Investigacion Judicial of Costa Rica has in its Departamento de Laboratorios de Ciencias Forenses with specialized sections in this discipline. A diversity of skills are performed of presumptive and confirmatory character for the presence of biological fluids, sexually transmitted diseases and identification of DNA by genetic markers. Updated information is given with respect to the correct interpretation of forensic biochemical expertises achievable for identification of semen, blood and human saliva in the investigation of sexual offenses. A scientific and legal language is used allowing the most of this information in the criminal process. The main objective has been to interpret, legal and scientifically, forensic biochemical expert evidence performed in human body fluids during the investigation of sexual offenses. A legal, doctrinal and scientific review is presented with compilation of related jurisprudence and criminology reports analysis of Seccion de Bioquimica of the Departamento de Laboratorios Forenses of the Organismo de Investigacion Juridica issued during the investigation of sexual offenses. Two types of attainable skills have existed for the identification of biological fluids, each with a different binding. In addition, it has been clear, due to the lexicon employed when making a forensic biochemist opinion, that to make a proper

    The discovery of the oncogenic virus and the analysis of its nucleic acid, together with the development of new biochemical technology have permitted the partial knowledge of the molecular mechanisms responsible for the cellular neoplastic transformation. This work, besides describing the discovery of the first oncogenic virus and the experiments to demonstrate the existence of the oncogenes, summarizes its activation mechanisms and its intervention in cellular metabolisms. Ionizing radiation is among the external agents that induce the neoplastic process. Its participation in the genesis of this process and the contribution of oncogenes to the cellular radioresistance are among the topics, which are referred to another topic that makes reference. At the same time as the advancement of theoretical knowledge, lines of investigation for the application of the new concepts in diagnosis, prognosis and therapeutical treatment, were developed. An example of this, is the study of the participation of the oncogen c-erbB-2 in human breast cancer and its implications on the anti tumoral therapy. (author) 87 refs., 7 figs., 3 tabs.

A idade dos pacientes variou entre 18 e 58 anos, sendo 26 do sexo masculino e 9 do feminino. Todos os pacientes apresentavam níveis de uréia acima de 100 mg/dl e creatinina acima de 5,0 mg/dl. 10 pacientes foram mantidos com hemodiálise crônica, 13 com diálise peritoneal semanal e 10 com tratamento clinico conservador (controles. Foram realizadas medidas da condução nervosa motora nos nervos mediano, ulnar e peroneiro em todos os pacientes, concomitante com a avaliação clínica. Os pacientes foram divididos em grupos, conforme a intensidade da neuropatia presente. Os sintomas mais freqüentes foram diminuição do senso de vibração, câimbras e hipoestesia distai para tacto. O nervo mais afetado foi o peroneiro (97,82%, seguido do mediano e ulnar. O procedimento dialítico alterou pouco a condução nervosa, quando as aferições eram realizadas antes e depois da mesma diálise. Não houve nenhuma diferença estatisticamente significante entre os grupos de hemodiálise e diálise peritoneal na avaliação clinica ou eletroneurográfica. Em 7 pacientes seguidos por vários anos, a condução nervosa manteve-se estável em dois, aumentou em dois e baixou em três, acompanhando a evolução dos sintomas. Nos três que pioraram, houve desenvolvimento paralelo de hiper-paratireoidismo secundário. Os autores concluem que o nervo peroneiro é o que melhores condições fornece para o seguimento e avaliação clinica dos pacientes com uremia, apresentando tendência para diminuir a condução nervosa, quando existe piora da sintomatologia, sem relação com o tipo de diálise empregado.

    Full Text Available Foi feita uma revisão critica da literatura sobre cardiopatia da Doença de Chagas, discutindo-se os principais aspectos clínicos desta cardiopatia á luz da experiência por nós adquirida nestes últimos anos. A evolução dos conhecimentos clínicos sobre esquisotripanose pode ser sintetisada em três fases: a A primeira corresponde á descoberta da doença, feita por Chagas, e á descrição por ele e seus primeiros colaboradores das manifestações clínicas essenciais da nova entidade mórbida, na qual distinguiu a forma aguda e várias formas crônicas. b Na segunda fase, a pesquisa orientou-se essencialmente pela busca dos casos de infecção aguda, havendo considerável duvida a respeito da realidade clinica das formas crônicas da infecção. Durante um longo período raros casos de cardiopatia crônica foram publicados. Ate o momento acual (1948 encontram-se na literatura estrangeira 134 casos de cardiopatia crônica chagásica, dos quais 9 autopsiados; ate fins de 1944, o numero de casos publicados no Brasil, fora de Lassance, era de 45, dos quais 3 autopsiados. c A terceira fase ou fase atual, tende a caracterisar-se por um interesse particular nos casos de infecção crônica, orientando-se porém a pesquisa cli¬nica essencialmente pelas manifestações da cardiopatia. Contribuições recentes de ordem clínica e experimental trouxeram ampla confirmação as idéias de Chagas a respeito desta cardiopatia e colocaram-na em posição de entidade clinica de realidade indiscutível. Sua importância social esta sendo determinada e os dados disponíveis já lhe apontam relevante significação em certas regiões. Mais de 600 casos de cardiopatia crônica chagásica foram publicados no Brasil nestes últimos quatro anos.

Specifically, three different expression protocols were compared, differing in their genetic constructs, ie, a simple native histidine-tagged VP6 sequence, VP6 fused to thioredoxin, and VP6 obtained with the newly described small ubiquitin-like modifier (SUMO fusion system. Our results demonstrate that the histidine-tagged protein does not escape the accumulation in the inclusion bodies, and that SUMO is largely superior to the thioredoxin-fusion tag in enhancing the expression and solubility of VP6 protein. Moreover, the VP6 protein produced according to the SUMO fusion tag displays well-known assembly properties, as observed in both transmission electron microscopy and atomic force microscopy images, giving rise to either VP6 trimers, 60 nm spherical virus-like particles, or nanotubes a few micron long. This different quaternary organization of VP6 shows a higher level of immunogenicity for the elongated structures with respect to the spheres or the protein trimers. Therefore, the expression and purification strategy presented here – providing a large amount of the viral capsid protein in the native

    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.

Este trabajo se realiza con personas con síndrome Down, comprendidos entre las edades de  25 a 40  años,  del consejo popular ¨Centro¨  de la ciudad de Santa Clara.  El diagnóstico realizado a estas personas derivó que  presentaban deficiencias en la esfera psicomotora, y  las  necesidades  psicomotrices  y  recreativas  se  satisfacían  de  manera superficial, lo cual trajo aparejado que la integración social fuera baja, así como el nivel de satisfacción de la familia. Para solucionar esta situación se diseña e implementa un conjunto de Actividades Físico–Sociales, integrado por: actividades rítmicas de expresión corporal y actividades sociales, las cuales incluyen presentaciones en contextos científicos de la Cultura Física y presentaciones en contextos comunitarios. Los Expertos valoraron de “Bastante adecuado” el conjunto de Actividades Físico – Sociales propuesto. Entre los resultados más relevantes de la investigación está la contribución  que  hace  el conjunto de Actividades Físico- Sociales a la integración de personas con síndrome Down a entornos normalizados, obteniéndose  mejorías en el  desarrollo  psicomotor,  la  satisfacción  de  la familia  y  la integración social.

Los factores de predicción de mayor riesgo de lesiones fueron trabajar en la calle muchas horas diurnas y realizar presentaciones callejeras, incluso después de controlar por factores sociodemográficos; específicamente, la adición de una hora de trabajo diurno aumentó el riesgo de lesión en 1,4%. Los niños que realizaban presentaciones callejeras presentaron una tasa de lesiones tres veces mayor que los niños que se dedicaban fundamentalmente a la venta de productos. Los niños varones, los de mayor edad y los de Quito presentaron mayor probabilidad de sufrir lesiones de moderadas a severas que las niñas, los más jóvenes y los que vivían en las otras ciudades estudiadas. CONCLUSIONES: Se requieren intervenciones para reducir el considerable riesgo de lesiones a que están sometidos los niños que trabajan en las calles de las ciudades de América Latina.

De manera infrecuente, puede presentarse el Zoster Sine Herpete, condición en la cual se presenta la distribución dermatómica del dolor en ausencia de lesiones dérmicas, convirtiendo el diagnóstico en un reto clínico. Caso clínico: Hombre de 69 años con dolor periorbitario, epifora, ptosis y pérdida de la aducción del ojo derecho. Los estudios imagenológicos y de laboratorio fueron normales, descartando así las principales causas de parálisis del nervio oculomotor. Se hizo diagnóstico presuntivo de Zoster Sine Herpete y se inició prueba terapéutica con valaciclovir, observándose resolución total de la sintomatología seis semanas después. Discusión: Este caso puede ser el primero en describir una parálisis parcial dolorosa del nervio oculomotor como única manifestación clínica de la reactivación del Virus Varicela Zóster y busca alertar al personal médico sobre una enfermedad latente que hace de sus reapariciones una gama de presentaciones no siempre fáciles de identificar.

Durante la misma, José relata su salida política como una consecuencia no bus-cada de una serie de acciones felizmente encadenadas desde el reclamo de los “jóvenes del barrio” de una casa para su familia hasta el agradecimiento a Balestrini (entonces intendente, pasando por la urbanización de Villa Torres. El rastreo se orienta a com-prender algunos sentidos de la política desde la perspectiva de José, asumiendo sus pre-sentaciones como un elemento importante de su propia forma de hacer política.

    Full Text Available Los autores presentan una actualización del tratamiento antipsicótico de la psicosis, centrándose en tres aspectos: la elección del fármaco antipsicótico, el problema de la adherencia y los tratamientos aún en fase de investigación. El antipsicótico a elegir en el tratamiento debe tener en cuenta tanto características individuales de cada paciente, preferencias, como características clínicas de la enfermedad. Se revisan las principales guías de tratamiento para hacer una buena elección del fármaco atendiendo al mecanismo de acción y perfil de efectos secundarios, respuesta clínica, fase de la enfermedad, pacientes resistentes, etc. Uno de los grandes problemas del tratamiento farmacológico en la psicosis es conseguir una buena tasa de adherencia al mismo, para ello se revisan las estrategias psicofarmacológicas, psicoterapéuticas y psicosociales que puedan favorecerla. La investigación actual se centra en la búsqueda de nuevos fármacos con características de atipicidad similar a los ya existentes (bloqueo de múltiples receptores, agonismo parcial dopaminérgico, fármacos atípicos ya conocidos con nuevas presentaciones, principalmente de acción retardada que puede favorecer la adherencia y nuevas dianas, especialmente la acción sobre la vía glutamatérgica.

  1. Towards the carbon fibers in the building industry

    Directory of Open Access Journals (Sweden)

    Miravete, A.

    2001-12-01

    Full Text Available There are two mainstreams in the building industry in the area of carbon fibers: rehabilitation and use as building material. The using of carbon fiber as a building material is taking place slower than as rehab system due to the very low cost of traditional building materials, the limitations of composite structure manufacturing processes and the conservative building regulations concerning materials in all the industrialized countries. However, these three issues are being solved in a very efficient way, as we will see along the coming paragraphs of this paper. This paper is split in two parts, first the carbon fiber as a material system, its typologies, manufacturing processes and industrial presentations will be described. Second, rehab and building applications will be analyzed.

    En el área de fibra de carbono en la construcción hay actualmente dos líneas de trabajo: reparaciones e implantación en obra: La implantación en la obra civil está avanzando más despacio que la utilización en reparaciones debido al bajo coste de los materiales tradicionales, a la limitación de procesos de fabricación de estructuras de materiales compuestos y al conservadurismo de las normativas de edificación y obra civil en todos los países industrializados. Sin embargo, los tres asuntos mencionados están siendo abordados con eficiencia, como se explicará más adelante. En el presente artículo, se va a describir, el primer lugar, la fibra de carbono, sus tipos, procesos de fabricación y presentaciones industriales. En segundo lugar se tratarán las aplicaciones en la construcción, haciendo énfasis en las reparaciones y en la implantación en obra civil.

  2. Existential Dimensions in the Socio-Legal Sphere: Introduction

    Full Text Available This introduction addresses the relevance of existentialist philosophy for understanding the indeterminacies and instabilities of late-modern society. Whilst existentialist thought is often misunderstood and subsequently unexplored, all the contributors to this special edition accept the basic premise that human existence is inescapably contingent and indeterminate. This introduction provides a short overview of the articles and reflects on themes such as destabilization and reintegration. All the articles are based on contributions to the workshop 'Law, Jurisprudence, Governance and Existential Indeterminacy', held at the International Institute for the Sociology of Law, Onati, Spain, 23-24 May 2013. Esta introducción aborda la relevancia de la filosofía existencialista para comprender las indeterminaciones e inestabilidades de la sociedad tardía. Aunque a menudo el pensamiento existencialista se ha malentendido y por consiguiente, no se ha explorado, todos los participantes de este número especial aceptan la premisa básica de que la existencia humana es ineludiblemente contingente e indeterminada. Esta introducción ofrece un breve resumen de los artículos y reflexiona sobre temas como la desestabilización y reintegración. Todos los artículos se basan en las presentaciones del workshop 'Law, Jurisprudence, Governance and Existential Indeterminacy', celebrado en el Instituto Internacional de Sociología Jurídica, Onati, España, los días 23-24 de mayo de 2013.

    Hugo Calabria Díaz

    Full Text Available En la década de los 90 los Postes Prefabricados de Fibra (PPF se introdujeron al mercado como alternativa a los sistemas metálicos o cerámicos. Hasta la fecha se mantienen en uso, modificando de manera constante sus presentaciones comerciales y estrategias de fijación. Sus cualidades mecánicas como su bajo Módulo Elástico (ME similar al dentinario, introducen un nuevo paradigma en la rehabilitación del Diente Endodonticamente Tratado (DET: .ldquo;el poste debe acompañar en forma solidaria la flexión de los tejidos dentarios frente a las cargas.rdquo;. Sus actuales cualidades estéticas, la fácil remoción y la posibilidad de su cementado adhesivo, los han convertido en una alternativa válida a las soluciones convencionales. Sin embargo, algunos resultados contradictorios junto con la importante dificultad de lograr hibridación en la dentina radicular, mantienen interrogantes a resolver en el futuro. Se indican en casos en donde se prevea retratamiento, en pacientes jóvenes, de alta exigencia estética y toda vez que se quiera y pueda eludir los costos de aleaciones nobles. En el presente artículo se analizan los fundamentos clínicos y experimentales de distintos autores, extrapolándose consideraciones prácticas para su uso. Los mismos se ilustran en un caso clínico para un paciente joven, con antecedente de traumatismo y con altas expectativas estéticas

    Alén de la Torre MT

    2010-03-01

    Full Text Available En los últimos años la disponibilidad de presentaciones de anticonceptivos hormonales se ha incrementado notablemente ya que la prevención de embarazos no deseados se valora como una de las principales medidas preventivas dentro de un sistema sanitario desarrollado. La eficacia de los anticonceptivos orales, usados adecuadamente, supera el 99%. En el uso habitual la efectividad se sitúa en torno al 92%, lo que parece indicar que el cumplimiento en muchas mujeres no es perfecto1. Nuevas vías de administración pretenden obtener, ante las formas orales tradicionales, mejoras farmacotécnicas y farmacodinámicas con el fin de facilitar la integración de su uso en el estilo de vida de la mujer y reducir la incidencia de efectos adversos. Entre estas nuevas vías de administración de anticonceptivos combinados destacan los parches transdérmicos con norelgestromina y etinilestradiol que, al evitar el efecto de primer paso consiguen una mayor biodisponibilidad lo que permite dosis menores y menos efectos secundarios2. Otra vía novedosa es el anillo vaginal con etinilestradiol y etonogestrel, con alta eficacia anticonceptiva y buen control del ciclo3. Ambas nuevas vías de administración de los anticonceptivos hormonales ofrecen alternativas que pueden resultar interesantes para las usuarias, basadas en una mayor facilidad de uso que mejoraría el cumplimiento. En la elección del método son tan importantes los criterios médicos como las preferencias de la mujer, por lo que se ha considerado interesante conocer las ventajas e inconvenientes que las usuarias encuentran en su uso frente a los anticonceptivos hormonales tradicionales por vía oral.

    2018-05-01

    Full Text Available La hipnosis es un tema controversial y estigmatizado. Las múltiples investigaciones de las últimas décadas han permitido tanto derrumbar mitos, como evidenciar sus mecanismos y aplicaciones, y cómo estos contribuyen al bienestar de las personas. El objetivo de este trabajo es describir las aplicaciones actuales de la hipnosis clínica en el contexto latinoamericano. Con este fin se realizó una revisión sistemática de la literatura en las bases de datos Lilacs y SciELo, empleando los términos “hipnosis”, “hipnosis clínica” y “Latinoamé- rica”. Se incluyeron revisiones de la literatura, artículos originales que tuvieran poblaciones latinoamericanas y presentaciones de caso, publicados entre 1990 y el 2016, escritos en español. La búsqueda inicial arrojó 202 artículos; después de eliminar replicaciones y los que no cumplían criterios de inclusión, 20 artículos fueron incluidos en la revisión. Las aplicaciones de la hipnosis descritas incluyen manejo del dolor, preparación a la cirugía, tabaquismo, problemas gastrointestinales y otras condiciones médicas, aplicaciones en niños y adolescentes, etcétera. Desafortunadamente, los estudios revisados tienen importantes falencias metodológicas, lo que dificulta extraer conclusiones sólidas. A pesar de que la hipnosis es eficaz, práctica, costo-efectiva y aplicada en una gran variedad de problemas clínicos, la evidencia que avala su uso en el contexto latinoamericano es muy limitada. Se requieren investigaciones con una metodología más rigurosa que permitan evidenciar su eficacia en este contexto.

    In order that the tools of CAD (Design Attended by Computer) that are offered in the market are really useful, they must combine the criteria and experiences of the expert designers with the specifications and practices established in the electrical company. This includes, from the introduction to the information system of the available input data and its design criteria, to obtaining the required output information. In the present work the methodology developed by the Instituto de Investigaciones Electricas (IIE) in the design of power transmission lines that integrates the Comision Federal de Electricidad (CFE) requirements in the design of its transmission power lines is an advanced computer tool that results in obtaining better designs. Some of the most important aspects are the reduction of the used working time, the cost of the designed line, its reliability, the flexibility in the information handling and the quality of presentation. [Spanish] Para que las herramientas de diseno asistido por computadora que se ofrecen en el mercado sean realmente utiles deben conjuntar los criterios y experiencias de los disenadores expertos con las especificaciones y practicas establecidas en la empresa electrica. Esto incluye desde la introduccion al sistema de la informacion de datos de entrada de la que se dispone y de sus criterios de diseno hasta la obtencion de la informacion de salida que se requiere. En el presente trabajo se resume la metodologia desarrollada por el Instituto de Investigaciones Electricas (IIE) en el diseno de lineas de transmision, que integra los requerimientos de la Comision Federal de Electricidad (CFE) en el diseno de sus lineas de transmision en una herramienta de computo avanzada y que redunda en la obtencion de mejores disenos. Algunos de los aspectos mas importantes son la reduccion del tiempo de trabajo empleado, el costo de la linea disenada, su confiabilidad, la flexibilidad en el manejo de informacion y la calidad de presentacion.

    Full Text Available Las imágenes cartográficas, como otros géneros de imágenes, nos ofrecen formas de mirar e imaginar el mundo de la manera en que éstas lo presentan. Sin dudas, éstas constituyen una de las imágenes más presentes en la cultura visual: informes y artículos de distintos géneros, publicidades y presentaciones apelan a ellos, con frecuencia, para mostrar y afirmar las peculiaridades que presentan determinados procesos y fenómenos. Proponemos discutir aquí la permanencia de una imagen cartográfica en la geografía escolar en Argentina así como algunas de sus implicancias. Finalmente, intentamos evidenciar las posibilidades que se abren en la enseñanza y en la conformación de imaginarios geográficos al introducir visiones cartográficas del mundo que discuten y confrontan con los discursos visuales hegemónicos. Cartographic images, as well as other sort of images, offer different ways of visualizing and imagining the world. This type of images have an important place in visual culture: articles, summaries, advertisements and public presentations use them in order to show different phenomena. We propose to discuss the presence of one kind of cartographic image in schooling geography in Argentina. Finally, we attempt to point out the possibilities that are opened up with the introduction of other world’s cartographic visions.

    Full Text Available La miocarditis es una enfermedad inflamatoria del músculo cardiaco no asociada a anormalidades valvulares y en ausencia de enfermedad isquémica. Su prevalencia e incidencia se desconocen, ya que se presenta de manera subaguda o con síntomas iniciales inespecíficos. Su fisiopatología consta de tres fases: aguda ( 15 días–aclaramiento viral insuficiente y perpetuación del proceso inflamatorio, que conduce a remodelamiento cardiaco y falla cardiaca. Como agente etiológico más frecuente se describe el Parvovirus B19 y el herpes virus humano 6. Entre las manifestaciones clínicas: dolor torácico, arritmias, en lactantes (letargo, taquipnea, dificultad respiratoria leve, etc., puede iniciar con pródromo viral, disfunción ventricular o muerte súbita. Tiene cuatro posibles presentaciones clínicas: asintomático, miocarditis aguda, fulminante o miocardiopatía crónica dilatada. El electrocardiograma detecta anormalidades entre el 93 al 100%; la resonancia magnética nuclear cardiovascular con gadolinio es de mayor uso, principalmente en la biopsia endomiocárdica. El tratamiento se basa en la monitorización hemodinámica del paciente, la evaluación de la necesidad de diuréticos, inhibidores de la enzima convertidora de angiotensina, betabloqueadores no selectivos, soporte inotrópico, antiarrítmicos o, en casos severos, el requerimiento de soporte mecánico cardiovascular. Se evalúa el uso de inmunoglobulina y, de manera controversial, el de inmunosupresor y antiviral. El pronóstico es variable y depende de factores inherentes al ambiente y al huésped. Se realizó una revisión actualizada de la literatura.
