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

The region has areas by the characteristics of the environment has been impossible to use agricultural and forestry. Serpentinite soils developed on frequently drew attention to the high degree of infertility, caused by nutrient deficiency and excess toxic metal content. The results of general physical and chemical properties have been analyzed of the total metal content and biochemical parameters of 28 soils on serpentinite in A Coruna Galicia, Spain. The infertility of soil organic matter, nutrients and low microbial activity and biochemistry have been caused by high level of pH and nutritional imbalance due to the high content of Mg{sup 2+}. OM (organic matter) content, total N, soluble P and exchangeable K{sup +}, were lower due to the underdevelopment of vegetation and the potential toxic effects that have metal on the biological activity in the middle.

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.

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.

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.

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.

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 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)

The association between radiographic presentation of tuberculosis (TB), pulmonary and extrapulmonary, and the count of CD4 T lymphocytes in patients infected with Human Immunodeficiency Virus (HIV), are investigated. The order has been to achieve a diagnosis and isolation early of coinfected patients. A retrospective analysis was performed of the clinical history, chest radiograph, CD4 T lymphocyte count of 25 HIV-infected patients with documented pulmonary or extrapulmonary tuberculosis diagnosis. 18 patients diagnosed (72%) with radiologic atypical skipper, 14 of them with significant immunosuppression (TB patients with CD4 T count <200 / mm {sup 3}), while only 6 (24%) with radiologic typical skipper of TB was associated with negative sputum smears (p=0.06). In HIV patients with CD4 T lymphocyte counts T <200 / mm {sup 3}, no respiratory symptoms and atypical radiographic pattern, may be suspected active TB, even with negative sputum smears.

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.

Full Text Available In recent years increasing research attention has been devoted to the definition and development of presentation skills. As an interactive oral discourse type, the presentation is characterised by specific speech acts, of which cooperative acts have proved to be of a highly developmental nature (Sazdovska, 2009. The aim of the present paper is to report on a study which investigated the metadiscursive realisations of interactional acts in English major novice presenters’ speeches as well as their correlation with raters’ holistic perceptions of presentation quality.En los últimos años se ha acentuado la investigación sobre el arte de la presentación oral. Según Sazdovska (2009, cada tipo de presentación tiene su discurso característico, pero todas las presentaciones comparten rasgos interactivos que se manifiestan de manera más o menos intensiva. Puede ser una destreza que se desarrolla con la práctica.

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.

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.

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.

[The preparation and characterization of fine dusts carried out in the Clinica del Lavoro di Milano in support of experimental studies].

Science.gov (United States)

Occella, E; Maddalon, G; Peruzzo, G F; Foà, V

1999-01-01

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

TUMOR DE MASSON DE CAVIDAD ORAL: PRESENTACIONES CLÍNICAS

Directory of Open Access Journals (Sweden)

ENRIQUE COSCARÓN-BLANCO

2018-05-01

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 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. The software is available in the INTERNET at the site: http://www.unicamp.br/ib/bioquimica/ensino.

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

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.

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.

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

El trabajo intentará interrogar y analizar el valor de los rasgos invariantes del autismo a la luz de la diversidad fenomenológica de las presentaciones, diversidad que lo posiciona como entidad de límites vagos, variables, imposible de aprehender por una clínica comportamental sin criterio organizador. En esa vía, se intentará cernir lo que persiste como constante dentro del llamado “espectro autista” para abordar el fenómeno autista desde la perspectiva de los aportes lacanianos, ya no cons...

¿La experiencia es la única forma de mejorar el discurso público en la ciencia?

Directory of Open Access Journals (Sweden)

Pablo del Monte-Luna

2015-01-01

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

Ruolo ed organizzazione della microbiologia clinica di domani

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 Starting from her clinical experience with migrant people, the author summarizes the theoretical and operational instruments in ethno-psychological field with a critical review of some key concepts: psyche and body, health and suffering, culture, ethnic group and race, diagnosis and treatment, individual and collective dimension. Especially, culture becomes most relevant when psychological competences are involved in cultural contexts which are different from our own: both when we work with foreign people in our country and when we are involved in mental health projects abroad. Transcultural clinic, ethnopsychiatry, critical medical anthropology and anthropology of contemporaneousness constitute the disciplinary horizon of therapeutic communications capable of managing caregiver’s and client’s cultural aspects.

Kovacs, L; Zamboni, C; Lourenço, T; Macedo, D

2015-01-01

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)

Factors Affecting Resident Satisfaction in Continuity Clinic-a Systematic Review.

Stepczynski, J; Holt, S R; Ellman, M S; Tobin, D; Doolittle, Benjamin R

2018-05-07

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.

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.

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. 

Concentrations of ions and metals in blood of amateur and elite runners using NAA

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.

Full Text Available La temática del desarrollo, bajo diversas formas y presentaciones, ha sido una constante en el pensamiento social latinoamericano. El siglo XIX estuvo, en gran parte, dominado por el debate entre civilización y barbarie. 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. Dentro de la supuesta confrontación entre el Occidente avanzado y el Oriente atrasado, los latinoamericanos se sentían más cercanos del Oriente que del Occidente.

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 La infección del tracto urinario (ITU, con sus múltiples presentaciones clínicas, está entre las enfermedades infecciosas más frecuentes, tanto en pacientes ambulatorios como hospitalizados. 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.

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.

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)

Full text: According to nutrition sources an athlete needs per day at least one gram of potassium for keeping the correct mineral balance in the organism. Its deficiency or even instantaneous low concentration in blood can diminish the athlete performance originating nervous irritability, muscular weakness, and mental disorientation and in more several causes cardiac arrhythmias. In this study the K levels in blood were determined in athletes submitted to constant load exercise at treadmill at LABEX (Laboratorio de Bioquimica do Exercicio - UNICAMP, Brazil) using Neutron Activation Analyses (NAA). The blood samples were collected from male athletes, age 18 to 26 years, before and after the physical training. Immediately after the collection an amount of 10 micro liters of whole blood was transferred to the filter paper and dried for a few minutes using an infrared lamp. To determine the concentration of potassium each sample was irradiated in the nuclear reactor (IEA-R1, 2-4MW, pool type) at IPEN and was gamma counted using an HPGe Spectrometer of High Energy Resolution. The concentrations of the selected element, 1525keV related to the potassium activated 42 K, were calculated using in -house software.

Full Text Available Foi realizada uma pesquisa qualitativa e exploratória, na forma de um estudo de caso, em uma unidade de internação cirúrgica de um hospital universitário, que objetivou analisar o trabalho do enfermeiro sob a ótica da produção de cuidados em saúde e do exercício da clínica. Os sujeitos do estudo foram seis enfermeiros e foram realizadas observações não participantes, pesquisa documental e entrevistas em profundidade com posterior análise textual discursiva. Verificou-se que o trabalho da enfermagem é organizado segundo duas perspectivas interconectadas e interdependentes: a do modelo clínico, que compõe a estrutura-mestre de sua prática, e uma estrutura composta por elementos múltiplos e heterogêneos. O modelo clínico de assistência organiza-se como uma estrutura centrada que possibilita a resolutividade das necessidades biológicas e atua como base para a conexão de outros saberes e práticas que expandem o fazer do enfermeiro por meio de interligações com o ambiente.

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.

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

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.

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.

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.

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.

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.

Fracture liaison service in a non-regional orthopaedic clinic--a cost-effective service.

LENUS (Irish Health Repository)

Ahmed, M

2012-01-01

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.

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

Its deficiency or even instantaneous low concentration in blood can diminish the athlete performance originating nervous irritability, muscular weakness, and mental disorientation and in more several causes cardiac arrhythmias. In this study the K levels in blood were determined in athletes submitted to constant load exercise at treadmill at LABEX (Laboratorio de Bioquimica do Exercicio - UNICAMP, Brazil) using Neutron Activation Analyses (NAA). The blood samples were collected from male athletes, age 18 to 26 years, before and after the physical training. Immediately after the collection an amount of 10 micro liters of whole blood was transferred to the filter paper and dried for a few minutes using an infrared lamp. To determine the concentration of potassium each sample was irradiated in the nuclear reactor (IEA-R1, 2-4MW, pool type) at IPEN and was gamma counted using an HPGe Spectrometer of High Energy Resolution. The concentrations of the selected element, 1525keV related to the potassium activated {sup 42}K, were calculated using in -house software. The potassium levels were evaluated before and after the physical exercise and the data were compared with the normal range. (author)

Full Text Available Uwe Wollina1, Alberto Goldman21Department of Dermatology and Allergology, Academic Teaching Hospital Dresden-Friedrichstadt, Dresden, Germany; 2Clinica Goldman, Porto Alegre, Rio Grande du Sul, BrazilAbstract: Age is a significant factor in modifying specific needs when it comes to medical aesthetic procedures. In this review we will focus on young adults in their third decade of life and review minimally invasive aesthetic procedures other than cosmetics and cosmeceuticals. Correction of asymmetries, correction after body modifying procedures, and facial sculpturing are important issues for young adults. The implication of aesthetic medicine as part of preventive medicine is a major ethical challenge that differentiates aesthetic medicine from fashion.Keywords: acne scars, ice pick scars, boxcar scars, fillers 

External auditory canal atresia of probable congenital origin in a dog.

Science.gov (United States)

Schmidt, K; Piaia, T; Bertolini, G; De Lorenzi, D

2007-04-01

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.

Radiological-morphological synopsis of radiation-induced lung fibrosis

International Nuclear Information System (INIS)

Bublitz, G.

1977-01-01

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.

Two patients walk into a clinic...a genomics perspective on the future of schizophrenia

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

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.

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.

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 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].

The purpose of this study was to compare sexual function between women of infertile couples (AR) and women seeking tubal ligation (TL). Women who attended Setor de Infertilidade do Serviço de Ginecologia e Obstetrícia do Hospital de Clinicas de Porto Alegre (HCPA) or the Serviço de Orientação e Planejamento Familiar (SERPLAN) completed the Female Sexual Function Index, a questionnaire about sexual activity in the last 4 weeks. Scored data were collected on six different domains: desire, arousal, lubrication, orgasm, satisfaction, and discomfort/pain. The greatest positive correlation in the TL group was between orgasm and sexual satisfaction (0.798), and in group AR between desire and arousal (0.627). Infertile women and fertile women who want to undergo surgical sterilization have similar sexual satisfaction scores.

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).

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.

Biochemical and immunological characterization of the main products of crotoxin irradiation; Caracterizacao bioquimica e imunologica dos principais produtos gerados pela irradiacao de crotoxina

Energy Technology Data Exchange (ETDEWEB)

Nascimento, Nanci do

1995-07-01

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 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.

Full Text Available Estudo avaliativo de abordagem quantitativa, com amostra de 104 gestantes, com o objetivo de comparar os achados de infecções vaginais em gestantes obtidos por meio do fluxograma de corrimento vaginal com exames presentes na prática clínica da Enfermagem. Os dados foram coletados por meio de entrevista e exame ginecológico realizados de janeiro a julho de 2011. O fluxograma não se mostrou eficaz na identificação de candidíase e tricomoníase, apresentou baixa sensibilidade (0,0%; 50% e valor preditivo positivo (0,0%; 3,6% para as duas infecções e baixa especificidade para tricomoníase (46%. Mostrou-se satisfatório para vaginose bacteriana, com alta sensibilidade (100%, valor preditivo negativo (100% e acurácia (74%. Conclui-se que o emprego do fluxograma precisa ser reavaliado, visto que não foi eficaz em identificar infecções importantes em gestantes. Os esforços para o desenvolvimento de testes eficazes devem ser contínuos, com intuito de prevenir a disseminação de infecções e reduzir tratamentos desnecessários.

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)

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

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.

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.

(Deformaciones: violencia y narrativa en Centroamérica

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.

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.

We evaluated the doses of radiologists, anesthesiologists and nursing staff of the Hospital de Clinicas de Porto Alegre, through measures with dosimeters of the OSL type, distributed in up to six regions of the body of these professionals. Until now were accompanied 33 cholangiography procedures and 29 embolization procedures. As a preliminary result, it was possible to identify a wide variation between doses of the professionals of the same function in each procedure. In overview, the dose of the professionals presented in descending order as a radiologist 1> radiologist 2 > anesthetist > nursing. (author)

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)

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.

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.

Full Text Available A fractura por insuficiência óssea, resulta de uma carga normal ou repetitiva, aplicada a um osso desmineralizado ou osteoporótico1. As fracturas pélvicas por insuficiência, nomeadamente do sacro e do púbis, são relativamente frequentes nos idosos2. Contudo, as fracturas da asa do ilíaco são raras, e quando documentadas estão frequentemente associadas a outras fracturas pélvicas3. A osteoporose pós-menopausa constitui o factor predisponente mais comum. Outros factores de risco incluem: artrite reumatóide, corticoterapia prolongada, insuficiência renal crónica, radioterapia e as alterações mecânicas após artroplastia da anca1.

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

Stereotactic Radiosurgery is a treatment technique that uses narrow beams of radiation focused with great accuracy in a small lesion. The introduction of micro multi leaf collimators (mMLC) allows this technique to reach a higher degree of dose conformation of the target lesion allowing a smaller irradiation of critical structures and normal tissues. This paper presents the results of the acceptance tests and commissioning of a Varian 6EX linear accelerator dedicated to radiosurgery associated with the BrainLab micro multi leaf collimator installed in the Hospital das Clinicas da Faculdade de Medicina da USP (HC-FMUSP) and establish feasible quality assurance program for the services that employ this special technique. The results of the acceptance tests were satisfactory and are willing with the specifications provided by the manufacturer and the commissioning tests were within the international recommendations. The tests and measures that are part of quality control process should be specific to each treatment unit, and the need, frequency and levels of tolerance

1996-11-01

Personnel monitoring data collected in the Radiotherapy, Diagnostic Radiology and Hemodynamics Departments of the Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto - USP during the interval from 1986 to 1995 were analyzed. The data were classified according to the profession of the workers and compared to those collected in a previous period (1973-1982). Internationally established criteria, published published in the ICRP 35 and 60 were used together with additional Brazilian criteria (CNEN NE 3.01) to optimize personnel monitoring such that the required radioprotection is provided. The results show that 80% of the workers need not be monitored because their doses will not exceed 3/10 the annual limits. An economy of about US$10,200 in monitoring cost per year could be realized as well as reduction in the hospital clerical costs expended to maintain the records. The improvements gaining by reducing the number of monitored persons will not compromise the safety standard required for radiation protection. (author)

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.

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.

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.

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

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.

Se analizan el transporte mesoscopico y semiclasico en el regimen metalico, la transicion metal-aislante, y el regimen de tunel resonante. Los efectos de decoherencia en el transporte son tratados en terminos de modelos de D'amato-Pastawski. Finalmente se incluye una breve presentacion de fenomenos dependientes del tiempo.

Biochemical and immunological alterations of {sup 60} Co irradiated Bothrops jararacussu venom; Alteracoes bioquimicas e imunologicas do veneno de Bothrops jararacussu irradiado com {sup 60} Co

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.

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

RIASSUNTO. Il disturbo da uso di alcol (DUA) è uno dei disturbi psichiatrici più comuni nella popolazione generale. Il DUA è caratterizzato da un pattern di bere eccessivo, che si mantiene nonostante gli effetti negativi che l'alcol ha sul funzionamento lavorativo, sulla salute, sulle problematiche legali, sull'educazione e sulla vita sociale. Attualmente, il modello bio-psico-sociale è quello che spiega meglio il DUA. Infatti, molte ricerche hanno fornito evidenze su come il DUA sia una patologia multidimensionale. Variabili biologiche, psicologiche e socio-culturali entrano in gioco nell'eziologia, nella natura, nel mantenimento e nel cambiamento nel tempo del disturbo. La fase diagnostica è un momento importante del processo di cura, perché il successo del trattamento dipende in larga misura dall'esattezza e dall'adeguatezza della diagnosi. La diagnosi clinica si basa su una valutazione globale del funzionamento del paziente e utilizza il colloquio e gli strumenti psicometrici come mezzo di raccolta di informazioni. Questo articolo fornirà una panoramica delle dimensioni psicologiche più importanti da valutare e sui migliori strumenti psicometrici da usare per una diagnosi adeguata.

With the advent of techniques for treatment of high complexity, such as radiosurgery and stereotactic radiotherapy, there is an increased need to reduce spatial uncertainties due to the delivery of high doses per fraction. In this work the accuracy of the Infrared (IR) system BrainLab version 5.5 was evaluated from through the positioning of patients with cranial diseases, and then followed by the routinely implementation at the Hospital das Clinicas da Faculdade de Medicina da USP (HCFMUSP). The validation tests were performed by making use of an isocenter phantom from BrainLab which first evaluated the uncertainty due to the positioning and then its repeatability. Further analysis provided by measurements of 60 patients has been made performed and compared with an IR and localization's box for stereotactic coordinates. The greatest variations in all the tests and all the degrees of freedom can be considered less than 1.0 mm and 0.1 °, translational and rotational respectively, thus ensuring the accuracy of positioning system of patients required in techniques of high complexity.

Fractures and dislocations of the hand are some injuries most frequently encountered in trauma of the musculoskeletal system. In evaluating these lesions, in addition to physical examination, radiography, in at least two incidents, is the investigation of choice, and rarely is necessary the help of other images to establish the diagnosis and treatment. The image quality of X-ray examination is therefore essential. In this study, a homogeneous phantom hand was developed to be used in the optimization of images from hand using computed radiography system process. In this procedure were quantified thicknesses of different tissues that constitute an anthropomorphic phantom hand. To perform the classification and quantification of tissue was applied membership functions for histograms of CT scans. The same procedure was adopted for retrospective examinations of 30 patients of the Hospital das Clinicas, Botucatu Medicine School, UNESP (HCFMB-UNESP). The results showed agreement between the thicknesses of tissues that make up the anthropomorphic phantom and sampling of patients, presenting variations between 12.63% and 6.48% for soft tissue and bone, respectively.

To establish the need for a sequential radiological study to contribute, together with other specialists in the management of these patients, to achieve the best possible results with this type of treatment: rates of survival comparable to those obtained with mastectomy and the highest possible percentages of breast preservation with satisfactory cosmetic results. Studies of 200 patients who underwent conservative treatment for breast cancer at Clinica Puerta de Hierro in Madrid over the past five years.We assess the utility of the different imaging methods and their application in each specific case. An update of the literature is also carried out. Radiology plays a major role in the management of patients who undergo conservative treatment for breast cancer. We demonstrate the need to carry out, in the first place, preoperative radiological studies to aid in the proper selection of patients and, secondly, examination of the resected tissue and postoperative mammography to ensure that the surgical resection was performed correctly. Finally, follow-up studies be carried out to detect tumor recurrence as early as possible. (Author) 82 refs

Objective: The present study was aimed at evaluating the accuracy of magnetic resonance cholangiography in the assessment of the biliary anatomy in living liver donors in correlation with surgical findings. Materials And Methods: Fifty living liver donors were retrospectively evaluated at Hospital de Clinicas da Universidade Federal do Parana, Curitiba, PR, Brazil. Cholangiographic images were analyzed and results were compared with intraoperative findings. Only anatomical alterations that affected the surgical strategy and had not been previously observed at magnetic resonance cholangiography were considered as being in disagreement. Results: Anatomical variations were found in 7 donors at magnetic resonance cholangiography, and in 14 during surgery. Agreement between imaging and surgical findings was observed in 41 of the 50 patients, and disagreement in 9. Magnetic resonance cholangiography sensitivity, specificity, positive and negative predictive values, and accuracy were respectively 43%, 97%, 86%, 81% and 81.6%. Conclusion: Magnetic resonance imaging is a safe and non invasive method for preoperative evaluation of the biliary tract in living liver donors. However some anatomical abnormalities are not detected by magnetic resonance cholangiography. (author)

Full Text Available L’autismo è un disturbo pervasivo dello sviluppo neuropsicologico che interessa all’incirca un bambino su mille. Purtroppo, si tratta di un dato destinato ad aumentare, anche per via dell’interesse mediatico e scientifico che questa patologia è stata capace di richiamare intorno a sé. Da un lato, infatti, sono aumentate le richieste di screening presso i numerosi centri che monitorano questa complessa patologia neurologica e dall’altro sono migliorate le tecniche di diagnosi che sempre più spesso si avvalgono di esami genetici all’avanguardia in aggiunta alle ormai classiche interviste psicologiche. L’autismo pone, dunque, serie questioni all’attenzione della ricerca scientifica sia nel vasto campo delle neuroscienze che in quello della neuropsichiatria e della psicologia clinica. Ebbene: quel settore della filosofia che guarda alla scienza con interesse particolare, non può che seguire con partecipazione i progressi nella spiegazione di questa misteriosa patologia che, attualmente, resta un vero e proprio rompicapo per tutti coloro che hanno a che fare con la complessità dell’organizzazione cerebrale dell’essere umano.

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 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)

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.

The problem's scenario inherent to the patient is simulated by such process, using the volume element (voxel) as a unit of computational tracing. The head's voxel structure geometry has voxels with volumetric dimensions around 1 mm 3 and a population of millions, which helps - in that way, for a realistic simulation and a decrease in image's digital process techniques for adjustments and equalizations. With such additional data from the code, a more critical analysis can be developed in order to determine the volume of the tumor, and the protection, beside the patients' medical images were borrowed by Clinicas Oncologicas Integradas (COI/RJ), joined to the previous performed planning. In order to execute this computational process, SAPDI computational system is used in a digital image process for optimization of data, conversion program Scan2MCNP, which manipulates, processes, and converts the medical images into voxel structures to input files and the graphic visualizer Moritz for the verification of image's geometry placing.

Human Immunodeficiency Virus and Hepatitis B virus are blood borne pathogens that can be transmitted through blood transfusion and could pose a huge problem in areas where mechanisms of ensuring blood safety are suspect. This study became necessary in a population where most of the blood for transfusion is from commercial blood donors. A total of 130 donors comprising 120 commercial donors and 10 voluntary donors were tested for antibodies to human immunodeficiency virus and hepatitis B surface antigen in Benin city using Immunocomb HIV - 1 and 2 Biospot kit and Quimica Clinica Aplicada direct latex agglutination method respectively. Thirteen (10%) samples were HIV seropositive and 7(5.8%) were HBsAg positive. The age bracket 18 - 25years had the highest numbers of donors and also had the highest number of HBsAg positive cases (7.8%) while the age group 29 - 38years had highest number of HIV seropositive cases. High prevalence of HIV antibodies and Hepatitis B surface antigen was found among commercial blood donors. Appropriate and compulsory screening of blood donors using sensitive methods, must be ensured to prevent post transfusion hepatitis and HIV.

This research was carry out due to the low presence of PET/CT projects in Venezuela in this moment, which consisted of the implementation and evaluation of a protocol for the acceptance and implementation of a hybrid tomograph PET/CT Discovery ST located in the nuclear medicine service at the Hospital de Clinicas Caracas. For this work, two references were used to provide a basic set of tests established and accepted by almost all manufacturers, such references are: NEMA 1994 PET and Spanish Protocol for Quality Control for Radiology CT. In general, we found that the smallest lesion in a functional image that this tomograph can resolve is {approx} 6mm. The spatial resolution of an anatomical image was resolved through 8 pl/cm. Likewise, this tomograph is able to produce a uniform anatomical and functional image, with very little noise and radiation scattered once the correction was done, referring to the test of co-registration accuracy of PET and CT shows that there is an excellent correspondence between the image of PET (functional) and the image of CT (anatomic), a basic parameter in a study of PET/CT.

We investigated scientific publications in laboratory medicine originating from mainland China, Hong Kong and Taiwan over the past 10 years. The information about articles published in the included journals were determined by computer-searching on PubMed and data were extracted independently and analyzed in relation to the number of articles. From 2000 to 2009 there were 1166 articles published in laboratory medicine journals from the major Chinese regions (mainland China, Hong Kong and Taiwan). This exceeded Japan, Germany, the United Kingdom and France from 2005 onwards. Also, the number of articles from mainland China exceeded those from Hong Kong and Taiwan from 2004 onwards. The average impact factor (IF) from Hong Kong ranked the first, followed by mainland China, and then Taiwan. Clinica Chimica Acta seems to be the most popular laboratory medicine journal among Chinese authors. Over the past 10 years, Chinese authors have been more and more active in the field of laboratory medicine. Mainland China seems to have caught up to Hong Kong and Taiwan regarding publication of papers in this field. Copyright 2010 Elsevier B.V. All rights reserved.

To examine the effects of a six-week body weight-support treadmill training (BWSTT) program on center-of-mass control and gait independence in chronic, incomplete spinal cord injury (iSCI) patients. Descriptive. Clinica Los Coihues. Neurorehabilitation center in Santiago, Chile. 17 chronic iSCI patients and 17 healthy subjects. An instrumented sway (ISway) test was performed before and after the implementation of a six-week BWSTT program. The standing balance of participants was measured by Normalized jerk (NJ) and root mean square (RMS). These values were used to assess the standing balance of participants, and were correlated with the scores obtained on the Walking Index Spinal Cord Injury (WISCI) II test. Significant differences were found in standing balance (i.e., through NJ) after the BWSTT program (P = 0.016), but no significant differences were found in RMS values for postural sway (P = 0.693). None of the patients obtained improved WISCI II scores pre- vs. post-intervention. While a BWSTT program can improve center-of-mass control in iSCI patients, no effects were recorded for gait independence. National Clinical Trials, registry number NCT02703883.

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.

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.

Full Text Available A lo largo de esta última década, diferentes programas nacionales, provinciales y municipales se combinaron para la edificación de viviendas e infraestructura en Villa Torres, dando forma al “proceso de urbanización”. José, que “no entendía nada de polí-tica” cuando comenzó en 1999, se desempeña como funcionario responsable del Pro-grama de Urbanización de Villas y Asentamientos de La Matanza desde 2005. En este artículo me interesa analizar cómo José cuenta su salida política. Para ello, parto de una entrevista realizada por un grupo de cientistas sociales en 2007, en el marco de un diagnóstico del barrio en vistas de la elaboración de políticas de inclusión social. 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 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.

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.

2014-01-01

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

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.

Clinical Training of Medical Physicists Specializing in Nuclear Medicine (Spanish Edition); Capacitacion clinica de fisicos medicos especialistas en medicina nuclear

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 increasingly 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 nuclear medicine. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists who are based in a 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 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 for Research, Development and Training related to Nuclear Science and Technology (RCA) for the Asia-Pacific region. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in this region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in nuclear medicine was started in 2009 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experience of clinical training in Australia, Croatia and Sweden and was moderated by physicists working in the Asian region. The present publication follows the approach of earlier IAEA publications in the Training Course Series, specifically Nos 37 and 47, Clinical Training of Medical Physicists Specializing in Radiation Oncology and Clinical Training of Medical Physicists Specializing in Diagnostic Radiology, respectively. This approach to clinical training has been successfully tested in Thailand, with three other Member States currently undergoing testing, and is believed to be generally applicable to the medical physics community in general.

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.

This study aims to evaluate the repeatability of symmetry and flatness of the photon beam of 6 MV linear accelerator Oncor Impression, Siemens, from the Radiotherapy Department of the Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto - USP. In total they were collected 102 measures, weekly, through two-dimensional detector of ionization chambers, Matrixx Evolution, IBA Dosimetry, connected to a computer with software OmniProI'mrt. The isocenter of the linear accelerator was placed in the center of the sensitive volume of the detector with solid water plates above and below these. Data were collected with 100 UM, with field size 10 x 10 cm². The flatness and symmetry values were calculated by the software used. The first measurement of this work was used as reference, the others were compared with it, taking into account the values of permissible variation for these parameters. The minimum, maximum and average value were analyzed. The literature indicates that the flatness and symmetry values should not vary by more than 2 and 3%, respectively. The results of this work show that the values of these parameters for the linear accelerator study are within the permissible variations in protocols and are therefore able to appropriate clinical use.

We conducted a prospective, descriptive study in the Clinica Anglo Americana, a prívate institution taking care of patients from a medium-high socioeconomic level in Lima. The goal of the study was to determine the frequency of histologic findings in liver biopsies performed by laparoscopy or percutaneously in patients with overweight (body mass index > 25 kg/m2) or obesity (body mass index > 30 kg/m2), and to evaluate the correlation with antropometric variables such as BMI, waist circumference, history of diabetes or hyperlypidemia, and biochemical variables like glycemia, lipid profile, aminotransferases and AST/ALT ratio. Between the years 2001 and 2006 50 patients were biopsied, 29 with overweight and 21 with obesity. Eighteen had simple steatosis and 22 had Non-alcoholic steatohepatitis (NASH) (44%), so 40 patients (80%) had some form of fatty liver. Five patients (10%) had cirrhosis confirmed by biopsy, and in all of them the finding of cirrhosis was completely incidental. Sixty four percent of patients with NASH were obese, like the 5 cirrhotics in our series. Herein we illustrate that in a relatively small sample of patients with obesity and overweight like ours, we found all the forms of the liver steatosis spectrum, from simple steatosis to cirrhosis, with a high frequency of NASH.

The applied investigation and experimental development project described in this paper has been carried out by Grupo Ingenieria ClInica of the Universidad Tecnologica Nacional together with two Special Education Schools dependent on the Ministry of Education of Cordoba Province. Its aim is the development of computer access assistive tools for students with mobility limitations, and with or without intellectual problems that need adaptations to access to a computer in order to learn, communicate, work, etc. On the other hand, it demonstrates the benefits that the use of a computer gives to these students. The evaluation of their performance was made trough Dr. Marianne Frostig's Developmental Test of Visual Perception and reading and writing graphic tests, comparing the results of the tests made on paper with those made on computer. Thus, an interdisciplinary team was formed by Engineering, Psychology and Special Education professionals, and 40 students were evaluated. The design of the mouse and keyboard had some adaptations. At present, the rating test stage is being achieved, and the preliminary results allow us to anticipate that pupils with psychomotor disabilities may manifest their perceptual ripeness and reach education in a more efficient way through the use of informatics tools according to their needs and possibilities

Full Text Available La práctica de la enfermería involucra la enfermera en decisiones y acciones al enfrentar las situaciones cotidianas de la clinica. En esas ocasiones, la enfermera usa conocimiento cientifico, la experiencia anterior, conceptos y la intuición para percibir las situaciones y desempeñar las acciones. Esa acción constituye una fuente de conocimiento que puede ser obtenido por medio de metodologías que siguen el enfoque interpretativo. El objetivo de este trabajo es presentar analíticamente la filosofía de la Ciencia-Acción en su relación con la construcción del conocimiento de la enfermería. La Ciencia-Acción es discutida como una metodología nueva en las ciencias sociales y su filosofía es tratada en relación a la epistemología de la enfermería. Este abordaje es recomendado para la enfermería porque focaliza la reflexión y destaca la práctica como fuente del conocimiento. Se concluye que la Ciencia-Acción tiene potencial para el avance de la teoría de la enfermería y del conocimiento de la práctica.

Temsirolimus 175 mg once-weekly for 3 weeks, followed by 75 mg once-weekly intravenously dosed (175/75 mg) is approved in the European Union for treatment of relapsed/refractory mantle cell lymphoma (MCL). A phase IV study explored whether similar efficacy, but improved safety could be achieved with 75 mg without 175 mg loading doses (ClinicaTrials.gov: NCT01180049). Patients with relapsed/refractory MCL were randomized to once-weekly temsirolimus 175/75 mg (n = 47) or 75 mg (n = 42). Treatment continued until objective disease progression. Primary endpoint: progression-free survival (PFS). Secondary endpoints included overall survival (OS) and adverse events (AEs). Median PFS was 4.3 versus 4.5 months (hazard ratio [HR] 0.731; 80% confidence interval [CI], 0.520-1.027), and median OS 18.7 versus 11.0 months (HR 0.681; 80% CI, 0.472-0.982) with 175/75 mg versus 75 mg. There were fewer patients with serious AEs, dose reduction, or death with 175/75 mg (57.4%, 48.9%, and 48.9%) versus 75 mg (73.8%, 64.3%, and 65.1%). Temsirolimus 175/75 mg remains the preferred dosing regimen for relapsed/refractory MCL.

This work aims to present a computational process of conversion of tomographic and MRI medical images from patients in voxel structures to an input file, which will be manipulated in Monte Carlo Simulation code for tumor's radiotherapic treatments. The problem's scenario inherent to the patient is simulated by such process, using the volume element (voxel) as a unit of computational tracing. The head's voxel structure geometry has voxels with volumetric dimensions around 1 mm{sup 3} and a population of millions, which helps - in that way, for a realistic simulation and a decrease in image's digital process techniques for adjustments and equalizations. With such additional data from the code, a more critical analysis can be developed in order to determine the volume of the tumor, and the protection, beside the patients' medical images were borrowed by Clinicas Oncologicas Integradas (COI/RJ), joined to the previous performed planning. In order to execute this computational process, SAPDI computational system is used in a digital image process for optimization of data, conversion program Scan2MCNP, which manipulates, processes, and converts the medical images into voxel structures to input files and the graphic visualizer Moritz for the verification of image's geometry placing.

The meaning of the term "medico competente" - usually adopted in Italy to indicate the occupational physician - is little known. To describe the origins of the word "medico competente" in Italy. We conducted a comprehensive analysis of the Italian legislation from the end of the nineteenth century to the present day. In the United Kingdom, occupational physicians were originally named as "certifying surgeon" (1833) and "appointed surgeon" (1860). In Italy, the term "medico delegato" was introduced to indicate the physician who visited child laborers (1886), while the word "medico competente" was first used in some propaganda leaflets of the Clinica del Lavoro of Milan in 1910. This term was officially used in Italian legislation in 1927 and was preferred to "medico di fabbrica" (factory physician) in the post-World War II period. Since 1982, the term "medico competente" has started to be considered as a synonym of occupational physician in Italian laws. The name "medico competente" appears to derive from a legislative imposition rather than from a voluntary choice developed in a medical and scientific context. Nowadays, Italian occupational physicians should be stimulated to find scientific, ethical, and professional meanings in this term, so helping to enhance their figure in modern society.

Sogno, immagini e disagio psichico: una cura per l'anima

Full Text Available Nella dimensione concettuale e terapeutica della psicologia analitica il lavoro con le immagini si pone come una sorte di spartiacque che caratterizza la specificità e l’identità della clinica junghiana, terreno di incontro col mondo delle psicosi, avvicinandosi al mondo dei deliri e delle allucinazioni come aspetti fenomenologici dove la dimensione personale si interseca con quella archetipica e il senso della propria esistenza ha potuto trovare un contenitore forse unicamente attraverso la voce dei deliri e delle immagini patologizzanti. In tal senso, le immagini accompagnano lungo il viaggio della vita, albergano nei ricordi delle storie prive di fiducia e di amore e possono condurre alla follia oppure rappresentare una ancora di salvezza in un mare tempestoso su una nave senza nocchiero. L'immaginazione è quindi da intendersi come attività creatrice, forza propulsiva che spinge e conduce l'individuo a mettersi in gioco e a valorizzare la dimensione interna non solo come portatrice di aspetti distruttivi e mostruosi, ma anche come possibilità di immaginare e non fantasticare la possibilità che ci possa essere uno spazio per la trasformazione del proprio passato in una storia riscritta in un altro modo, con un altro significato che sia quello dell'unione e non della frantumazione schizofrenica.

To find and describe perceptions, beliefs, knowledge and attitudes adopted by healthy people regarding liver disease, who attend at three medical institutions. To estimate how the academic and socioeconomic level operate as determinant factors. Descriptive transversal study that includes a 31 question-questionnaire made in a group of 390 healthy people who were in the waiting rooms at Hospital Cayetano Heredia (HNCH), Policlinico Peruano Japones (PPJ) and Clinica Angloamericana (CAA), reflecting low, medium and medium-high socio economic status respectively. Data was processed with SPSS software. We found that 218/390 (56%) people had higher education level, and 64% were women. "Eating high-fat meals" had the highest percentage (91%) among perceptions of liver disease. "Bad breath" and "heartburn" were referred as symptoms of liver disease, among people with a higher education level. Less than 50% of people knew about routes of transmission of hepatitis B, associated with its prevention and treatment. Beliefs and wrong perceptions about liver disease are prevalent among people; dyspepsia was inaccurately associated. There is an inappropriate knowledge about routes of transmission, preventive measures and treatment, which was reflected in people with lower education level as well as in those with higher education and socioeconomic level.

A descriptive retrospective study of acute intoxication cases registered at the Complexo Hospitalario de Pontevedra (CHOP) between January 2005 and December 2008 was performed to find out the number and types of poisoning cases treated, their distribution according to patient's sex and age, chronology, type of toxic agents involved, intentionality, history, symptoms, clinical development, treatment and toxicological analysis used for diagnosis. Data were recorded using Clinica and IANUS software and consulting all paper records of patients with symptoms of poisoning. Data from a total of 1893 patients with a mean age of 35.6 ± 17.6 years (66% men) were included. Highest rates of poisoning were recorded on Saturdays and Sundays during the summer months (June, July and August). Drugs of abuse were the most common toxic agents (70.4%), ethyl alcohol accounting for 61% of these cases, which often involved males and with people with high degrees of dependency. In second place was poisoning resulting from the abuse of medical drugs, more commonly associated with females, and involving benzodiazepines in 73.2% of cases. The majority of these intoxications were intentional, and suicide attempts accounted for 18.8%. The problems most commonly resulting from the poisoning were neurological, and mortality rate was just 0.2%.

Construction of a homogeneous phantom for radiographic image standardization

International Nuclear Information System (INIS)

Pina, Diana Rodrigues de

1996-01-01

The principle of radiodiagnosis consists in the fact the X-ray beam is attenuated at different degrees by distinct tissues. For this reason, the anatomical structures have distinct radiological opacities, that produce the radiographic image. The progresses in radiology are related to the development if new radiographic image formation systems that enable an amplification in the quality, with low dose and/or risk to the patient. The objective of this work is the sensitometric valuation of a screen-film combination, that is still the most used, for the standardization, of radiographic images. Thinking about this, were constructed homogeneous phantoms of the chest, skull and pelvis, for the calibration of X-ray beams, with the purpose of obtaining radiographic images of good quality, basing in the routine of a radiodiagnosis service and in the scientific knowledge. Questions were approached about the choice of the suitable equipment, that allow the obtention of k Vp and m As combinations, to produce radiographic images of good quality, and the reproduction of these combinations to any conventional equipment of diagnostic X-rays. Also presented are the comparison of the doses imparted by these combinations and those used in routine of the Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto's radiodiagnosis service.

Esto resulta evidente al considerar los avances en el diagnóstico y tratamiento del prolapso genital. Lamentablemente, gran parte de los urólogos femeninos, ginecólogos y uroginecólogos podrian asociar este avance con la sucesiva implementación de nuevos procedimientos quirúrgicos que han sido introducidos con un interés comercial, sin contar con resultados de estudios clinicos que avalen su uso. Esto resulta peor aún si consideramos el limitado conocimiento que todavia se tiene de la etiología y fisiopatología del prolapso de los órganos pélvicos. Sin embargo, esta última década trajo consigo un progreso importante en el diagnóstico, junto a un incremento considerable en el estudio clínico de la etiología de las disfunciones del piso pélvico. En este artículo discutiremos los últimos adelantos, y su importancia, tanto en la práctica clinica como investigación de la obstetricia y ginecología, enfocándonos en el diagnóstico y tratamiento del prolapso genital.

Full Text Available Gli studi in psicologia clinica e sociale evidenziano come l’incontro tra popolazioni provenienti da contesti etnici, sociali, culturali e psicologici molto diversi attivi una serie di meccanismi di tipo prevalentemente difensivo. E’ illusorio ritenere che l’incontro fra tali diversità, come nel caso dei fenomeni emigratori, si risolva attraverso processi d’integrazione che avvengano quasi “per natura”, al contrario vi sia sempre la necessità di una modifica di equilibri precedenti, analogamente a quanto avviene per consimili eventi sul piano biologico.L’articolo evidenzia come l’incontro con il fenomeno dell’emigrazione vada psicologicamente affrontato anche sul fronte della popolazione che riceve i nuovi individui, inclusi gli operatori e i clinici che si occupano in prima persona del fenomeno, aiutandoli ad adattare i propri confini geografici come modifica, sul piano psicologico, di confini interni, poiché questi ultimi sono i mezzi che identificano e riconoscono le differenze.Saranno utilizzate alcune esemplificazioni tratte da esperienze d’intervento psicologico clinico e sociale nei campi della consulenza educativa degli adulti, della medicina e della psicoterapia per mostrare a quali difficoltà interpretative siano sottoposti i propri abituali modelli culturali, clinici e operativi nell’incontro con realtà differenti e quali modalità possano facilitare osmosi e integrazione tra persone e culture.

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.

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 Este texto se basa en una investigación de campo “multi–situada” de siete años sobre el impacto del ciclo más reciente de exhumaciones de fosas comunes de la Guerra Civil española, llevada a cabo en diversos escenarios: exhumaciones, actos conmemorativos, conferencias académicas sobre la memoria, presentaciones de libros, conciertos musicales, encierros universitarios, asambleas, diversas ONG, grupos de trabajo con apoyo institucional, laboratorios forenses, exposiciones de arte, manifestaciones, etc. Explora la forma en la que los discursos y conceptos transnacionales de los derechos humanos se han ido convirtiendo paulatinamente en guías fundamentales de la acción de muchas de las asociaciones que promueven la conocida como “recuperación de la memoria histórica”, a medida que el debate ha ido creciendo, se ha sofisticado, institucionalizado y, finalmente, judicializado. En este sentido, la secuencia de informes de Amnistía Internacional sobre el proceso o el auto dictado por Baltasar Garzón el 16 de septiembre de 2008, la controversia generada por él hasta su inhibición el 18 de noviembre de 2008, y los sucesos derivados del proceso que se le ha abierto en el Tribunal Supremo han actuado como catalizadores de esta irrupción de los derechos humanos en los debates sobre la memoria, a través de figuras jurídicas como las de los “crímenes contra la humanidad”, las “desapariciones forzadas”, y otras.

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

Full Text Available La pregunta por la psique y su relación con lo femenino se encuentra soterrada en la actualidad por una sociedad que privilegia el logos y la tecnología como maneras de hacer lecturas efectivas del mundo y los sujetos. Venus o Afrodita, según su versión griega o romana, plantea en su mito una posibilidad de reflexión profunda acerca de lo femenino en íntima conexión con el psiquismo y el ejercicio de la psicoterapia. El privilegio de lo masculino y sus expresiones sociales en la forma de razón, competitividad, guerra y consumismo, han velado a lo femenino con representaciones que lo proscriben y desvalorizan mediante figuras como Eva o Pandora, en tanto sus presentaciones. La revisión de la “Gran Diosa” antigua y la exaltación de lo femenino como fuerza creadora y transformadora, permiten entenderlo como algo que está más allá de su reducción a la condición de objeto y restituyen al mito su capacidad de comprensión del ser humano a la luz de la psicoterapia como actividad de creación y transformación, en relación con los temas que encarna la Diosa como las emociones, la sexualidad y el cuerpo. Su análisis otorgará interrogantes que podrán contribuir en las construcciones acerca del psiquismo y de las fuerzas que intervienen en su dinámica.

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.

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)

With these pages La Medicina del Lavoro starts its 100th volume, so we have yet another historical occasion to celebrate the oldest occupational health journal in the world that is still publishing. Over the last few years we have had many occasions to celebrate, for example several anniversaries of the Journal (the 80th volume in 1989, 90 years in 1992, 100 years in 2001); the centenary of the foundation of the Clinica del Lavoro "Luigi Devoto" of Milan in 2001; the celebration of the 300 years' anniversary of the publication of De Morbis Artificum Diatriba by Bernardino Ramazzini, and we obviously hope to continue for many years to come in this positive outlook. One hundred volumes makes for a very large collection, with the highs and lows ofthe Journal's history (here we mean the variations in number of pages and physical size of the Journal). It is thanks to the Editors-in-chief(there have been very few so we can cite them all: Luigi Devoto, 1901-1936; Luigi Preti, 1936-1941; Enrico Vigliani, 1943-1992; e Vito Foà, 1992 to the present); the contributors who in various ways and with varying degrees of commitment but always with an exceptional personal participation, that it has been possible to reach 100 volumes, starting with C. Moreschi who, along with Luigi Devoto, was the first and sole editor at the Journal's foundation; up to the present extended and impressive editorial board; the printers (from the first. Tipografia Cooperativa, Via dei Molini in Pavia, to the latest: Casa Editrice Mattioli in Fidenza); the sponsors, including the most evident who, via advertising (rather limited as a matter offact), directly gave information about themselves, but also those who have often been or are behind the scenes, ensuring fundamental support which is not visible; content. articles, news, events, reports, ideas, opinions, photographs, tables, numbers... etc, which are really impossible to sum up.

Lina Bollani

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 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.

Full Text Available En 1990 se describió un síndrome caracterizado por discinesia apical transitoria, cambios en el electrocardiograma (ECG, mínima elevación de enzimas cardíacas y arterias coronarias normales. 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.

The 12-lead surface ECG is validated for differentiating supraventricular tachycardias (SVT) in humans. Despite the description of SVT in veterinary medicine, no studies have analyzed the electrocardiographic features of this type of arrhythmias in dogs. To describe the specific electrocardiographic criteria used to differentiate the most common SVT in dogs. Twenty-three dogs examined at Clinica Veterinaria Malpensa for SVT with the mechanism documented by electrophysiologic studies (EPS). Twelve-lead electrocardiographic variables obtained from 14 dogs with orthodromic atrioventricular reciprocating tachycardia (OAVRT) and 9 dogs with focal atrial tachycardia (FAT) were compared. Dogs with FAT had faster heart rates (278 +/- 62 versus 229 +/- 42 bpm; P= .049) and less QRS alternans (33 versus 86%; P= .022). P waves appeared during tachycardia in 22 dogs, with a superior axis in 100% of OAVRT and 22% of FAT (P < .001). OAVRT was characterized by a shorter RP interval (85.0 +/- 16.8 versus 157.1 +/- 37.3 ms; P < .001) and smaller RP/PR ratio (0.60 +/- 0.18 versus 1.45 +/- 0.52; P < .001). Repolarization anomalies were present in 64% of OAVRT and no FAT (P < .001). Multivariate analysis identified QRS alternans and a positive P wave in aVR during tachycardia as independent predictors of arrhythmia type. Electrocardiographic criteria used in people for differentiating SVT can also be applied in dogs.

The principle of radiodiagnosis consists in the fact the X-ray beam is attenuated at different degrees by distinct tissues. For this reason, the anatomical structures have distinct radiological opacities, that produce the radiographic image. The progresses in radiology are related to the development if new radiographic image formation systems that enable an amplification in the quality, with low dose and/or risk to the patient. The objective of this work is the sensitometric valuation of a screen-film combination, that is still the most used, for the standardization, of radiographic images. Thinking about this, were constructed homogeneous phantoms of the chest, skull and pelvis, for the calibration of X-ray beams, with the purpose of obtaining radiographic images of good quality, basing in the routine of a radiodiagnosis service and in the scientific knowledge. Questions were approached about the choice of the suitable equipment, that allow the obtention of k Vp and m As combinations, to produce radiographic images of good quality, and the reproduction of these combinations to any conventional equipment of diagnostic X-rays. Also presented are the comparison of the doses imparted by these combinations and those used in routine of the Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto`s radiodiagnosis service.

There are some sectors in the Health Area of the State University of Campinas (UNICAMP) that present great potential risks from the viewpoint of radiation protection. The aim of this work is to establish the basis a radiological protection program applicable to these sectors. The Diagnostic Radiology Services and the Laboratory of Cardiac Catheterization of the Hospital de Clinicas have been analyzed, as well as the Radiotherapy Services of the Center for Integral Assistance to the Women Health (CAISM). This work was mainly supported by national and international regulations related to the operative and employment aspects of the equipment and radiation sources used in the health area. Regulations related to area and individual monitoring of workers were also used. Results show that the interior of the rooms where the equipment and radiation sources are located is classified as controlled area, whereas the neighborhoods of the rooms are mostly free areas. In order to improve the radiological protection conditions, only some of the operative and employment aspects need to be modified regarding equipment and radiation sources. In this way, routine personal monitoring would not be further required. Since all the workers have their annual mean equivalent doses below 3/10 of the primary limits of the applicable equivalent dose, routine individual monitoring could be exempted.

Full Text Available BACKGROUND: The expression of CD56 is considered a bad prognostic factor for overall survival, lower rates or short complete remission and extramedullary invasion but the results are controversial. The importance of validating new prognostic parameters in acute leukemias was the reason to investigate the CD56 expression in blast cells of patients with acute myeloid leukemia. METHODS: A cohort of 48 patients treated at Hospital de Clinicas de Porto Alegre and diagnosed with acute myeloid leukemia as classified by the French-American-British group (FAB criteria using cell morphology, cytochemistry and flow cytometry were evaluated. RESULTS: Eight cases (16.7% were CD56 positive without correlation to age or gender. The highest incidence of CD56 positivity was in FAB subtypes M4 and M5. The death rate during induction was not significantly different between patients with and without CD56 expression (62.5% vs. 27.5%; p-value = 0.097. However, patients that expressed CD56 had significantly lower overall survival than those who did not (mean 4.0 months vs. 14.5 months; p-value = 0.03. CONCLUSIONS: The data suggest that expression of CD56 in acute myeloid leukemia may be indicative of poor prognosis because it is associated with a shorter overall survival. The death rate during induction was not significantly different despite an apparent difference in proportions between groups.

High sensitivity C-reactive protein (hs-CRP) is commonly used in clinical practice to assess cardiovascular risk. However, a correlation has not yet been established between the absolute levels of peripheral and central hs-CRP. To assess the correlation between serum hs-CRP levels (mg/L) in a peripheral vein in the left forearm (LFPV) with those in the coronary sinus (CS) of patients with coronary artery disease (CAD) and a diagnosis of stable angina (SA) or unstable angina (UA). This observational, descriptive, and cross-sectional study was conducted at the Instituto do Coração, Hospital das Clinicas, Faculdade de Medicina, Universidade de São Paulo, and at the Hospital Beneficência Portuguesa de Sao Paulo, where CAD patients referred to the hospital for coronary angiography were evaluated. Forty patients with CAD (20 with SA and 20 with UA) were included in the study. Blood samples from LFPV and CS were collected before coronary angiography. Furthermore, analysis of the correlation between serum levels of hs-CRP in LFPV versus CS showed a strong linear correlation for both SA (r = 0.993, p < 0.001) and UA (r = 0.976, p < 0.001) and for the entire sample (r = 0.985, p < 0.001). Our data suggest a strong linear correlation between hs-CRP levels in LFPV versus CS in patients with SA and UA.

Despite the attention that international Agencies give to the gender issue in situations of workplace bullying, few investigations have been performed on this topic. The aim of the study is describe the gender differences in victims of workplace bullying observed in an Italian survey. A total of 243 subjects (124 males and 119 females) were examined at the Centre for Occupational Stress and Harassment of the "Clinica del Lavoro Luigi Devoto" (University of Milan and IRCCS Foundation); they were selected among patients who met the criteria for being considered victims of negative actions at work leading to workplace bullying. Data regarding the person, workplace and the workplace bullying situation were collected by means of an ad hoc questionnaire. Analysis of the data, compared with those of IS-TAT 2002, showed a higher prevalence of females subjected to negative actions at work. In women, the risk of being subjected to negative actions leading to workplace bullying was shown to increase in the 34-44 age range and to decrease in higher age ranges; in men the risk remained elevated also after 55 years of age. In general, women were victims of negative actions regarding personal values related to emotional-relational factors, while men were attacked on their work performance. Sexual harassment, may mark the onset of other types of psychological harassment or can be one of its components.

Riassunto Negli ultimi anni abbiamo assistito a un fiorire di novità cliniche e scientifiche sulla celiachia (CE), ma forse la novità più importante che influenzerà il futuro della ricerca e della clinica in questo campo riguarda la storia naturale della malattia. Per molti anni si è creduto che la predisposizione genetica e l’esposizione al glutine fossero necessarie e sufficienti allo sviluppo della CE. Studi recenti, però suggeriscono che la perdita di tolleranza al glutine possa apparire in qualsiasi momento della vita a seguito di altri elementi. Inoltre, diversi fattori ambientali conosciuti per il loro ruolo nell’influenzare la composizione della microflora intestinale sono anche stati considerati legati allo sviluppo della CE. Tra questi fattori sono inclusi la modalità di parto, la dieta dell’infante e l’uso di antibiotici. A tutt’oggi, nessuno studio longitudinale di ampia scala ha determinato se e come la composizione del microbioma e il suo profilo metabolomico possano influenzare la perdita di tolleranza al glutine e il successivo sviluppo della CE in soggetti geneticamente predisposti. In questo articolo descriviamo uno studio prospettico, multicentrico e longitudinale su infanti a rischio per la CE che utilizzerà diverse tecniche per approfondire il ruolo che il microbioma intestinale ha durante i primi passaggi dello sviluppo della malattia autoimmune.

High-resolution medical images along with methods that simulate the interaction of radiation with matter, as the Monte Carlo radiation transport codes, have been widely used in medical physics procedures. These images provide the construction of realistic anatomical models, which after being coupled to these codes, may drive to better assessments of dose distributions on the patient. These anatomical models constructed from medical images are known as voxel phantoms (voxel - volume element of an image). Present day regular images are unsuitable to correctly perform skin dose distribution evaluations. This inability is due to improper skin discrimination in most of the current medical images, once its thickness stands below the resolution of the pixels that form the image. This paper proposes the voxel phantom reconstruction by subdividing and segmenting the elements that form the phantom. It is done in order to better discriminate the skin by assigning it more adequate thickness and actual location, allowing a better dosimetric evaluation of the skin. This task is an important issue in many radiotherapy procedures. Particular interest lays in Total Skin Irradiation (TSI) with electron beams, where skin dose evaluation stands as the treatment key point of the whole body irradiation. This radiotherapy procedure is under implementation at the Hospital das Clinicas da Universidade de Sao Paulo (HC-USP). (author)

MATERIALS AND METHODS: Here, we present our experience in the treatment of 123 cutaneous tumors of various types, including basal cell carcinoma (BCC, squamous cell carcinoma (SCC, Bowen's disease, erythroplasia of Queyrat, Paget's disease, and trichoepithelioma, with 5% imiquimod cream from 2003 to 2008 in the Cutaneous Oncology Group of the Dermatology Department of Hospital das Clinicas. Patients were divided into two separate groups according to their diagnosis and comorbidities; these comorbidities included epidermodysplasia verruciformis, xeroderma pigmentosum, albinism, basal cell nevus syndrome, Brooke-Spiegler syndrome, HIV, chronic lymphocytic leukemia, B-cell lymphoma, and kidney transplantation. Treatment duration, response to imiquimod, follow-up, recurrence, and local and systemic reactions associated with use of the drug were analyzed. Epidemiological data were obtained and cure rates were calculated. RESULTS: The ratio of women to men was 1.28:1, and the mean age was 63.1 years. Tumors were located mainly on the face, back, trunk, and legs. For patients with comorbidities, the overall cure rate was 38%. These specific patients demonstrated cure rates of 83.5% for superficial BCC and 50% for Bowen's disease. Aggressive BCC and superficial and nodular BCC did not present a good response to treatment. Trichoepitheliomas and nodular BCC showed a partial response, and erythroplasia of Queyrat showed a complete response. For patients without

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

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.

In Marfan syndrome, aneurysmatic enlargement of ascending aorta and dissection starting at the root are the most common cardiovascular complications. We present an infrequent case of a 15-year-old patient with a typical case of Marfan syndrome. CT disclosed an aorta and aortic arch of normal size with dissection originating distally with respect to the point where left subclavian artery arises. The disecction extended to descending aorta and to iliac and femoral arteries. Aortic rupture occurred in the arch, with massive hemothorax. The CT findings were confirmed at necropsy. 9 refs.

Towards the carbon fibers in the building industry

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.

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.

Full Text Available Los costos originados por trastornos cognitivos y demencias son significativos para los sistemas de salud. Según guías nacionales e internacionales, los fármacos recomendados para su tratamiento son inhibidores de colinesterasa (donepecilo, galantamina y rivastigmina y memantina. En la Argentina también son utilizados otros nootrópicos, galantamina, rivastigmina, vasodilatadores, vitaminas y antioxidantes. El objetivo del presente estudio es describir y comparar el patrón de prescripción de drogas para el tratamiento de trastornos cognitivos y demencias en las distintas regiones del país. Se realizó un estudio observacional retrospectivo a partir de las prescripciones (1 814 108 envases realizadas en la práctica clínica habitual durante el segundo semestre del 2008 y el primer y segundo semestre del 2009. El trabajo fue realizado sobre la población total del Instituto Nacional de Servicios Sociales para Jubilados y Pensionados. Se analizaron variables demográficas, cantidad y tasa de prescripciones, presentaciones y dosis utilizadas por regiones. Considerando todo el país, memantina fue la droga más prescripta en esos períodos, con un total de 570 893 envases. Memantina, donepecilo, rivastigmina e idebenona presentaron un incremento en las tasas de prescripción 2008-2009. Analizando los cambios regionales en tasas de prescripción, la memantina aumentó en el Noroeste y Noreste argentino, la idebenona en el Noroeste y la Patagonia y el donepecilo en el Noreste. Grupos de fármacos no recomendados fueron altamente prescriptos en todas las regiones del país. Algunos fueron indicados en adultos jóvenes o de mediana edad.

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.

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.

The hypothesis of this study was that juvenile pubic symphysiodesis (JPS) results in pelvic changes that can be identified radiographically in adult dogs. The medical records at the Clinica Veterinaria Vezzoni were searched for standard ventro-dorsal views of the pelvis of adult Labrador and Golden Retrievers that had undergone JPS or had not undergone surgery. The objective assessment of radiographs included the analysis of various pelvic measurements. Subjective evaluation of radiographs was undertaken by 18 specialists and 21 general practitioners and was based on five criteria relating to 1) the acetabular fossae, 2) the pubic symphysis, 3) the margin of the cranial pubic area, 4) the pubic rami, and 5) the obturator foramen. The radiographs of 42 Labrador Retrievers and 16 Golden Retrievers were evaluated. The most useful criteria were the radiographic measurement of the shape of the obturator foramen and two different ratios of length to width of the pubic rami; these values were significantly smaller in dogs after JPS. The pelvic canal width was the same in both groups. All objective measurements were repeatable within and between evaluators. The most reliable subjective criterion was number 4, followed by number 5 in Golden Retrievers and by 2 in Labrador Retrievers. Our objective and subjective evaluations were simple and yielded useful and repeatable results. There was no significant difference between general practitioners and specialists with regard to subjective evaluation, which indicates that these evaluation criteria can be used by small animal clinicians after minimal training.

Study of the correlation of brainstem auditory evoked potentials and magnetic resonance imaging in children with spastic cerebral palsy

International Nuclear Information System (INIS)

Fobe, Lisete Pessoa de Oliveira

1999-01-01

Central auditory evaluation in 21 children with cerebral palsy was done with brainstem auditory evoked potentials (BAEP) and correlated with brain magnetic resonance imaging findings (MRI); 12 boys and 9 girls between 5 and 12 years old were studied. All children had follow-up at the Institute of Orthopedics and Traumatology of Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo. The control group was done with 17 children, 10 boys and 7 girls (mean age 8.06 years, SD 2.27 years). The BAEP abnormalities were: decrease of latency of wave V; decrease of latency III-V and I-IV intervals at the right side. All patients has MRI supratentorial abnormalities and 11 had brainstem atrophy. The MRI pathologic findings were: ventricular enlargement (n=17 or 80.95%), cortical/subcortical atrophy (n=15 or 71.42%), left brainstem atrophy (n=11 or 52.38%), periventricular leukomalacia (n=10 or 47.61%), infarction in the left middle cerebral artery territory (n=6 or 28.57%), and malformations such as schizencephaly and colpocephaly (n=5 or 23.80%). The findings of the decrease latencies in children with cerebral palsy suggest the contribution of decussating auditory fibers at the lower and upper pons and midbrain, the lack of homogeneity of the surrounding volume of the conductor fibres and the presence of several concurrently active potential generators sources, should be facilitating mechanisms for the nervous input to brainstem.
