    Las extensas consecuencias de la pandemia del VIH/SIDA, además de la mortalidad directa, son bien conocidas. De manera adicional a la caída en la esperanzade vida, la epidemia ha producido varias consecuencias en las estructuras sociales y en la productividad económica, afectando de manera adversa a esferas enteras de la sociedad, como los sectores educativo y agrícola. Existe la tentación de considerar la relación entre el VIH/SIDA y la pobreza como algo lineal, es decir, como si la pobreza ...

Según la Teoría Social Cognitiva, el burnout puede producirse como consecuencia de una crisis de eficacia percibida (Bandura, 2001; Cherniss, 1993. Se espera que la percepción de obstáculos en el trabajo (Tiempo 1 genere una falta de eficacia percibida (Tiempo 2, que a su vez producirá burnout (i.e., agotamiento, cinismo y despersonalización (Tiempo 2. Los resultados de los análisis SEM (Structural Equation Modeling realizados en una muestra de 274 profesores pertenecientes a 23 centros de educación secundaria confirman que la presencia de obstáculos genera una falta de eficacia percibida, que a su vez genera burnout. De este modo, el burnout se asocia con una crisis de eficacia. Además, relaciones recíprocas muestran que el burnout incrementa la percepción de obstáculos, generándose una espiral negativa. Se discuten las limitaciones y las implicaciones prácticas del estudio.

Se realizó una investigación cualitativa, clasificándose el estudio como una investigación documental, no experimental. El diseño de investigación fue documental explicativo.Las unidades de análisis para el desarrollo de los tópicos investigados fueron las leyes y normas que rigen la materia de salud y seguridad laboral en nuestro país:LOPCYMAT (2005; Reglamento de la LOPCYMAT (2007; la norma técnicas de INPSASEL NT- 02-2008; las Sentencias del Tribunal Supremo de Justicia (2008, 2005, 2004, 2003, 2000; la Ley Orgánica del Trabajo (1997; el Código Civil (1982 y el Código Penal (2005 y los diferentes estudios e investigaciones desarrollados por instituciones e investigadores de prestigio internacional y nacional en materia de riesgos psicosociales. Se concluye, en primer lugar, que la responsabilidad legal de prevención de los riesgos psicosociales, recae sobre los mandos superiores: Gerentes, Ejecutivos, que actúan a nombre y por la empresa y finalmente se hace necesaria una adecuada comprensión de los riesgos psicosociales y sus factores para una prevención efectiva.

    Full Text Available El uso de computadores como apoyo pedagógico orientado a incentivar el interés y el desarrollo de nuevas formas de pensar y de solucionar problemas puede ser un instrumento útil en la enseñanza del código lector. Estudios realizados con preescolares y escolares han demostrado un mejor rendimiento escolar y un efecto positivo en habilidades de lectura, matemáticas, y en general cognitivas, en niños que utilizan un computador con software educativo quince a veinte minutos por día. El objetivo del presente estudio fue evaluar la progresión de las habilidades verbales, integración viso-motora y de lectura en niños que usaron computadores y compararlos con un grupo que continuó con la educación tradicional. Todos los niños fueron estudiados antes de iniciar la intervención pedagógica. La evaluación inicial mostró una puntuación inferior para la edad en todas las pruebas aplicadas. El 11% de la población estudiada se catalogó como en alto riesgo de tener problemas en el aprendizaje. En la segunda evaluación se encontró un cambio positivo respecto a la puntuación inicial. Sin embargo, a excepción de algunos ítems, no se encontraron diferencias signifi cativas al comparar los grupos de uso o no de computadores. En conclusión, las políticas acerca del uso de computadores deben ser revaluadas, pues los niños de nuestras escuelas públicas provienen de ambientes privados de oportunidades para el uso de tecnología

    Full Text Available A doença de Lyme é afecção sistêmica causada pela espiroqueta Borrelia burgdorferi, transmitida pelo carrapato. É descrita principalmente nos países do hemisfério norte, sendo pouco relatada no Brasil. O objetivo deste trabalho é documentar uma paciente com doença de Lyme que apresentou pupila tônica bilateral como única seqüela oftálmica da afecção. Trata-se de uma menina de 13 anos de idade, com diagnóstico de doença de Lyme, que apresentou paralisias facial periférica e do oculomotor bilaterais. Após recuperação do quadro neurológico manteve anisocoria, fraco reflexo fotomotor, amplitude de acomodação inferior ao normal, constrição pupilar tônica para perto e redilatação lenta em ambos os olhos. O teste com pilocarpina a 0,1% foi positivo em ambos os olhos, confirmando a suspeita clínica de pupila tônica bilateral. Este é o primeiro caso relatado de pupila tônica bilateral causado pela doença de Lyme.Lyme disease is a multisystemic disorder caused by Borrelia burgdorferi spirochete, transmitted by ticks. Mainly described in the northern hemisphere and rarely in Brazil. The purpose of this report is to describe a patient with Lyme disease who developed bilateral tonic pupil as the only remaining sign. A 13-year-old female with Lyme disease, presented with bilateral peripheral facial and oculomotor paralysis. After recovery from neurological abnormalities the patient sustained anisocoria, reduced fotomotor reflex, less than normal amplitude of accommodation, tonic pupil constriction for near objects and slow redilatation in both eyes. Dilute 0.1% pilocarpine test was positive in both eyes, confirming the suspicion of bilateral tonic pupil. This is the first case report of bilateral tonic pupil caused by Lyme disease.

    Full Text Available Topiramate is a drug used in the treatment of epilepsy, migraine, bulimia and other pathologies. We report a case of a 40-years-old woman, presented to the emergency department of ophthalmology with blurred vision in both eyes and bilateral acute angle closure. Her medications included topiramate started 6 days before Secondary angle closure glaucoma due to topiramate was diagnosed. The medication was discontinued and she was treated with topical antiglaucoma medications, intravenous mannitol and cyclopegics. At the 5-days follow-up visit, vision, intraocular pressure, and angle anatomy had returned to normal. The acute angle-closure glaucoma occurs due to edema of the ciliary body and uveal effusion that produces an anterior motion of the iris-lens diaphragm , with ocular hypertension and acute myopia .

    Full Text Available El catalizador de FCC está constituido por partículas de composición compleja donde el componente activo es una zeolita Y. En este trabajo se presentan los resultados texturales y estructurales de una zeolita USY comercial lixiviada, de una serie de catalizadores con 7, 15, 25, 35 y 45% de material activo y los de estos materiales desactivados hidrotérmicamente. Las muestras se caracterizaron por fluorescencia de rayos X (FRX, difracción de rayos X (DRX, resonancia magnética nuclear de silicio (29Si RMN y fisiadsorción de nitrógeno a 77 K. A partir de estos resultados se hallaron correlaciones entre el volumen de microporo y el contenido de zeolita y entre el grado de cristalinidad y el porcentaje de zeolita. Además, se encontró que un tratamiento con sólo 20% de vapor de agua a 1033 K durante 16 horas destruye los grupos estructurales Si(2Al y Si(3Al como reflejo de la dealuminización drástica que sufre el material.

Nació en Zaragoza, España, en 1923 y falleció prematuramente en San José, Costa Rica, en 1979. El Doctor Láscaris fue un prolífico ensayista y escritor de varios libros sobre filosofía y pensamiento en Costa Rica y Centroamérica. El ensayo Consecuencias de la noción de existencia es una refrescante reflexión de un tema que es tan vigente hoy como hace 30 años sobre las bases filosóficas, desde la óptica del existencialismo, de cuestiones controversiales sobre el momento en que el ser humano puede considerarse titular de todos los derechos de una persona o sobre los fundamentos éticos del control de la natalidad. Uno de los méritos del ensayo es que trasciende el dogma religioso que tan difícil hace las discusiones de estos temas.

Los efectos de este problema repercuten notablemente en aquellos que sobreviven, ya que las consecuencias a largo plazo del maltrato infantil son más perjudiciales para lasvíctimas y sus familias, y más costoso para la sociedad, que las lesiones agudas inmediatas que puedan producir. Las consecuencias a largo plazo para estos niños varían desde efectos nocivos en su desarrollo hasta trastornos psicológicos, psiquiátricos y orgánicos. Es importante resaltar que aún con muy buenas intervenciones no todas tienen el éxito esperado si no se hacen de manera correcta. Esindispensable contar con estrategias de prevención que incluyan personal bien entrenado, una supervisión adecuada, los recursos necesarios, y un tiempo mínimo óptimo para enfrentar el problema y obtener los mejores resultados. ______________________________________________________________________Domestic violence is one of the most common forms of violence found both domestically and internationally. Within these, child abuse has alarming figures. This is the subject of this review. The effects of this problem significantly impact on those who survive; their long-term consequences are most severe and expensive for victimized child and his/her family than associated primary physical injuries. Thelong-term consequences for these children range from adverse effects on its psycholigical development to psychological, psychiatric organic disoders. It is important to note that good speeches are not enough to achieve success if any intervention are not done correctly. All prevention strategies include well-trained staff, appropriate supervision, resources, and a optimal time for addressing this problem to get the best results.

    Full Text Available Acute dacryoadenitis is an uncommon condition that involves inflammation of the lacrimal gland. In rare instances, dacryoadenitis may be bilateral. A delay in proper treatment of an otherwise simple case of dacryoadenitis may lead to significant soft tissue morbidity such as cellulitis, lacrimal gland abscess, or orbital abscess. We report the case of a 24-year-old male who presented to the emergency department with acute bilateral dacryoadenitis. The patient′s symptoms did not respond to oral antibiotics and he subsequently required admission for intravenous antibiotics. During his hospitalization the patient had diagnostic testing to try to determine the etiology for his symptoms. The unique aspects of managing a case of bilateral dacryoadenitis as well as treatment recommendations are discussed in this case report.

    Full Text Available Relato de caso com acometimento bilateral do seio cavernoso causado por linfoma não-Hodgkin em um paciente com síndrome da imunodeficiência adquirida. Paciente de 51 anos infectado pelo vírus da imunodeficiência adquirida há dois anos, sem terapia antirretroviral, apresentou-se com acometimento dos V e VI nervos cranianos bilateralmente. Exame de tomografia computadorizada de órbitas mostrou-se dentro da normalidade. Como a hipótese diagnóstica principal era afecção do ápice orbitário ou do seio cavernoso, foi realizado exame de imagem por ressonância magnética que evidenciou lesão compatível com linfoma acometendo os seios cavernosos. Apesar da raridade dos linfomas primários do sistema nervoso central, essa condição deve ser considerada entre os diagnósticos diferenciais nos pacientes imunodeprimidos que apresentem oftalmoplegia e sinais radiológicos sugestivos de lesão infiltrativa do seio cavernoso.

    Full Text Available On 24 February 1895 most people in Cuba did not want a war of independence, because reforms for the island had been approved by the Madrid parliament. The reaction to the insurrection begun in Cuba on that date by the Spanish government of Antonio Cánovas del Castillo was to treat all Cubans as rebels. In 1896 Cánovas sent general Weyler to Cuba, and by the end of 1897 he had stopped the advances of the insurrectionists, but the forced removal of the rural population into urban settlements that he decreed in order to prevent their assistance to the insurgents, led to thousands of deaths by hunger and disease, and in the United States public opinion began to clamor for intervention in Cuba to expel Spain, and this was advised by people like the Consul General in Havana, Fitzhugh Lee. The war begun in 1895 for the independence of Cuba had as consecuences the war of the United States with Spain in 1898 and its transformation into a world power with the colonies that it took from Spain in Asia and America.El 24 de febrero de 1895 la mayor parte de los habitantes de Cuba no deseaba una guerra de independencia, porque se acababa de votar en el parlamento de Madrid por reformas liberalizantes para la isla. La reacción del gobierno de Antonio Cánovas del Castillo a la insurrección iniciada en Cuba en esa fecha fue no implementar las reformas y tratar a todos los cubanos como insurrectos. En 1896 Cánovas envió al general Weyler a Cuba, quien logró frenar el avance de los insurrectos, pero la reconcentración de los campesinos en centros urbanos que este decretó para privar de su apoyo a los insurrectos causó miles de muertes por hambre y enfermedad y en los Estados Unidos la opinión pública comenzó a favorecer la intervención en Cuba, acción aconsejada por expansionistas como el Cónsul General de los Estados Unidos en La Habana, Fitzhugh Lee.

Si bien el estudio de la movilidad laboral es relevante durante toda la vida laboral del individuo, es especialmente interesante cuando se centra en la etapa temprana del desarrollo de la carrera del individuo ya que el progreso durante esta fase determina, en buena medida, la trayectoria de carrera posterior. En este contexto, el objetivo del presente trabajo es el análisis de los antecedentes y consecuencias, relacionados tanto con las percepciones y evaluaciones de los trabajadores como con sus conductas, de un tipo específico de transición laboral, el cambio de nivel jerárquico, en una muestra de jóvenes durante la etapa temprana del desarrollo de su carrera. El estudio presenta un diseño longitudinal con dos momentos de recogida de datos. La muestra está formada por jóvenes trabajadores que pertenecen a dos grupos ocupacionales: usuarios y operadores aprendices en sistemas de información complejos, y operadores de máquinas y herramientas que desarrollan su actividad en procesos de producción y manufacturación. Los resultados sugieren que los jóvenes que son promocionados tienden a utilizar más estrategias de desarrollo de la carrera y más conductas de innovación en su trabajo. Además, se observa que el cambio de nivel jerárquico tiene consecuencias importantes tanto en las estrategias de ajuste como en las percepciones y repuestas afectivas de los jóvenes ante el trabajo.

El objetivo de este trabajo fue evaluar el cambio de las comunidades de lombrices de tierra y de algunas propiedades físicas, químicas y fisicoquímicas en suelos con SD en relación a pastizales naturales (PN, en la cuenca Gral. Deheza, Córdoba. Las lombrices de tierra se obtuvieron según el método del programa TSBF. Se observó un aumento de la compactación y una disminución en el contenido de materia orgánica (MO y del pH en los sitios con SD con respecto a los PN. La comunidad de Lumbricina estuvo dominada por lombrices endogeas, claves en los procesos edáficos al modificar tanto aspectos químicos como físicos del suelo. En SD disminuyó la población de Lumbricina de una media de 297 ind m-2 a 70 ind m-2 con respecto a los PN y aumentó la proporción de individuos en diapausa y juveniles. Esto se explica principalmente por la mayor compactación y el menor contenido de MO. El aumento de organismos juveniles y en diapausa también podría estar asociado a la influencia negativa del intenso uso de agrotóxicos. Se concluye que en la región estudiada, los suelos bajo SD estarían comprometidos en el cumplimiento de las «funciones ecosistémicas» que son la base de su calidad. Se plantea el interrogante sobre la sustentabilidad a largo plazo de esta práctica agrícola.No-till has been recognized as a low environmental impact management in relation to other crop systems.

    Full Text Available En el procedimiento de consecuencias diferenciales (PCD a un organismo se le presenta un estímulo (E1 en cuya presencia se requiere una respuesta (R1, que produce un reforzador específico (r1, y en presencia de un segundo estímulo (E2, se requiere una segunda respuesta (R2, que produce un reforzador distinto (r2, lo que resulta en un incremento en la velocidad de adquisición y precisión final en tareas de discriminación condicional. Una explicación basada en una teoría de dos factores establece que el uso de consecuencias diferenciales involucra la activación de expectativas del reforzador a través de un mecanismo pavloviano, las cuales promueven la activación de un sistema de memoria implícita en la solución de tareas de discriminación condicional. De acuerdo con esto, la expectativa del reforzador es una señal que guía la respuesta del organismo. Recientemente se ha demostrado el efecto del PCD en situaciones donde lo que se aprende no se observa directamente, como sucede en la manipulación de un intervalo de retención en la interferencia retroactiva.

  1. Consecuencias del abuso sexual infantil: una revisión de las variables intervinientes

    Directory of Open Access Journals (Sweden)

    David Cantón-Cortés

    2015-05-01

    Full Text Available En las últimas décadas el abuso sexual infantil (ASI ha suscitado un gran interés, tanto entre la comunidad científica, como en la sociedad en general, debido a su prevalencia y consecuencias a corto y a largo plazo. Aunque la mayoría de los estudios que han examinado las secuelas del ASI enumeran numerosas dificultades psicológicas, sociales, conductuales y físicas, ciertamente no todas las víctimas de abuso infantil muestran un daño significativo posterior, existiendo una amplia variabilidad en el ajuste de las víctimas. Ante esta diversidad el presente trabajo, tras realizar una revisión de las consecuencias a corto y largo plazo del ASI, pretende discernir cuales son las principales variables que determinan los efectos del abuso sobre la víctimas. Las características del abuso, víctima y agresor, los factores situacionales y, especialmente, las variables cognitivas de la víctima se han demostrado como eficaces para explicar la gravedad de la sintomatología. Concretamente, las investigaciones realizadas en los últimos años han encontrado que la sustitución de estrategias de afrontamiento de evitación por estrategias de aproximación, la eliminación de las atribuciones de autoinculpación e inculpación a la familia y de los sentimientos relacionados con las cuatro dinámicas traumatogénicas y la promoción de un estilo de apego seguro resultarían beneficiosos a la hora de prevenir futuros problemas causados por la experiencia de abuso.

    Full Text Available Introducción: El abuso sexual en menores de edad es uno de los tipos de maltrato infantil con peores repercusiones en sus víctimas y que usualmente coexiste con otros tipos de violencia. Incluye tanto agravios que no involucran contacto físico como aquellos que sí lo hacen, lo que cubre una amplia gama de posibilidades. Objetivo: Debido a lo trascendental de esta problemática, se realizó está revisión bibliográfica con el fin de exponer la importancia del tema de abuso sexual en menores de edad, sus aspectos generales, consecuencias y medida preventivas. Síntesis de datos: El abuso sexual es frecuente. Las víctimas suelen ser mujeres a pesar de que existen ciertos factores de riesgo que predisponen a ciertos niños a ser agredidos, y sus abusadores por lo general son personas cercanas a ellos. Las consecuencias tanto a corto como largo plazo abarcan todos los aspectos del ser humano y la magnitud de su gravedad dependerá de diversos factores. Existen métodos de prevención primaria y secundaria, que van desde programas educativos y campañas publicitarias hasta medidas judiciales. Conclusiones: Es necesaria más información relativa al abuso sexual en menores y es imprescindible liberarse de los estereotipos en torno a esta problemática para detectar a tiempo posibles casos de abuso. Toda víctima deberá obtener una atención individualizada posterior al suceso, dirigida a atenuar las secuelas. El abordaje del abuso sexual se deberá hacer desde diversas perspectivas y todos estamos a cargo de su combate.

    Full Text Available De acuerdo con los modelos teóricos que llaman la atención sobre la consideración del burnout como un proceso transaccional entre la persona y el medio laboral (Cherniss, 1980; Moreno-Jiménez, González-Gutiérrez y Garrosa, 2001, el presente trabajo examina las dimensiones de desgaste profesional que, junto con los factores antecedentes organizacionales y profesionales del síndrome específicas de la profesión de Terapia Ocupacional, se encuentran asociadas a los diferentes niveles de consecuencias planteadas en la literatura sobre el síndrome. Para ello se empleó una muestra de 110 terapeutas ocupacionales que desempeñan su actividad clínica en la Comunidad Autónoma de Madrid. A través del desarrollo de un análisis de regresión jerárquica se ha observado la existencia de asociaciones altamente significativas entre el síndrome y la presencia de consecuencias adversas para la salud del individuo, así como para su área interpersonal y para la propia organización en la que desarrolla su actividad laboral, siendo el agotamiento emocional la dimensión más asociada a las mismas. Junto a ello, se ha identificado la relevancia explicativa de los problemas extralaborales que afectan al área laboral, así como de otros factores que podrían actuar a través de la generación de desgaste, como son la sobrecarga de trabajo, las características de la tarea, la falta de apoyo y reconocimiento por parte del equipo, y el miedo a la malpráctica.

Así los ancianos sarcopénicos tienen más dificultad para caminar o lo hacen más lentamente, para subir escaleras, para realizar las actividades básicas de la vida diaria. Estas dificultades aumentan el riesgo de caídas y por lo tanto de fracturas. También afecta a la formación de hueso, a la tolerancia a la glucosa y a la regulación de la temperatura corporal. Además la dependencia es un factor de riesgo de mortalidad.The concept of sarcopenia implies loss of muscle mass and function. It is a condition that accompanies aging, although it not always has clinical consequences.

The main clinical consequences of sarcopenia relate with functional independence. Thus, the sarcopenic elderly has greater difficulty walking, or do it more slowly, climbing up stairs, or doing basic daily living activities. These difficulties increase the risk for falls and, thus, fractures. They also affect bone formation, glucose tolerance, and body temperature regulation. Besides, dependency is a mortality risk factor.

Más que los daños materiales y las víctimas, el efecto fue profundamente simbólico, debido a que tres de los signos más representativos de los Estados Unidos de América habían sido destruidos. Mientras el 11/9 fue rápidamente etiquetado y vendido al mundo como una precondición para los tiempos turbulentos por venir, Atocha en Madrid significó el final de la administración Aznar.

    1997-11-01

    We reported a 67-year-old woman with bilateral caudate head infarcts. She developed sudden mutism followed by abulia. She was admitted to our hospital 2 months after ictus for further examination. She showed prominent abulia and was inactive, slow and apathetic. Spontaneous activity and speech, immediate response to queries, spontaneous word recall and attention and persistence to complex programs were disturbed. Apparent motor disturbance, gait disturbance, motor aphasia, apraxia and remote memory disturbance were not identified. She seemed to be depressed but not sad. Brain CT and MRI revealed bilateral caudate head hemorrhagic infarcts including bilateral anterior internal capsules, in which the left lesion was more extensive than right one and involved the part of the left putamen. These infarct locations were thought to be supplied by the area around the medial striate artery including Heubner's arteries and the A1 perforator. Digital subtraction angiography showed asymptomatic right internal carotid artery occlusion. She bad had hypertension, diabetes mellitus and atrial fibrillation and also had a left atrium with a large diameter. The infarcts were thought to be caused by cardioembolic occlusion to the distal portion of the left internal carotid artery. Although some variations of vasculature at the anterior communicating artery might contribute to bilateral medial striate artery infarcts, we could not demonstrate such abnormalities by angiography. Bilateral caudate head infarcts involving the anterior internal capsule may cause prominent abulia. The patient did not improve by drug and rehabilitation therapy and died suddenly a year after discharge. PMID:9503974

    A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery. PMID:21106320

    Full Text Available Morgagni hernia is a rare congenital diaphragmatic hernia. It is seen rarely bilaterally. Patients are usually asymptomatic. Therefore, diagnosis may be delayed until adulthood. Significant morbidity can occur in case complications arise and diagnosis is delayed. The patient, a 74 year-old female, presented in this article, was admitted to the emergency department with abdominal pain, vomiting, and shortness of breath. The plain abdominal radiograph of the patient revealed bowel obstruction and suspicious appearence in favor of the diaphragmatic hernia on both sides of the sternum. Computed tomography revealed bilaterally incarcerated Morgagni hernia with strangulated omentum in the right side of the sternum and a part of colon in the left side of sternum. Incarcerated organs were withdrawn to peritoneal cavity and defects of hernia were sutured primarily on laparatomy. Because bilateral incarcerated Morgagni hernia can be seen rarely, this case was reported.

  11. Efficacy of bilateral pallidotomy.

    Unilateral pallidotomy is a safe and effective treatment for medically refractory bradykinetic Parkinson's disease, especially in those patients with levodopa-induced dyskinesia and severe on-off fluctuations. The efficacy of bilateral pallidotomy is less certain. The authors completed 11 of 12 attempted bilateral pallidotomies among 150 patients undergoing pallidotomy at New York University. In all but one patient, the pallidotomies were separated by at least 9 months. Patients were selected for bilateral pallidotomy if they exhibited bilateral rigidity, bradykinesia, or levodopa-induced dyskinesia prior to treatment or if they exhibited disease progression contralateral to their previously treated side. The Unified Parkinson's Disease Rating Scale (UPDRS) and timed upper-extremity tasks of the Core Assessment Protocol for Intracerebral Transplantation (CAPIT) were administered to all 12 patients in the "off" state (12 hours without receiving medications) preoperatively and again at 6 and 12 months after each procedure. The median UPDRS and contralateral CAPIT scores improved 60% following the initial procedure (p = 0.008, Wilcoxon rank sums test). The second pallidotomy generated only an additional 10% improvement in the UPDRS and CAPIT scores ipsilateral to the original procedure (p = 0.05). Worsened speech was observed in two cases. In the 12th case, total speech arrest was noted during test stimulation. Speech returned within minutes after stimulation was halted. Lesioning was not performed. These results indicate that bilateral pallidotomy has a narrow therapeutic window. Motor improvement ipsilateral to the first lesion leaves little room for further improvement from the second lesion and the risk of speech deficit is greatly enhanced. Chronic pallidal stimulation contralateral to a previously successful pallidotomy may prove to be a safer alternative for the subset of patients who require bilateral procedures. PMID:15096015

    2009-10-01

    Paragangliomas of the head and neck are rare neoplasms presented as cervical mass, generally bilateral, that arise from chemoreceptors located at the carotid bifurcation (carotid body tumors), along the vagus nerve (vagal paragangliomas), and in the jugular fossa and tympanic cavity (jugulotympanic paragangliomas). They are typically asymptomatic at the beginning, highly vascular, slow-growing and compressing the surrounding anatomic structures. Only radical surgery is the curative treatment for paragangliomas. We present a case of a 62- year-old woman with a diagnosis of bilateral neck paragangliomas where surgical removal was judged burdened by excessive risk because of the size of the tumor.

    Full Text Available This article analyzes the effects of the number of siblings and their sex composition as well as other indicators of individualization which are intertwined with the development of a beanpole type kin structure on interchanges among generations in Spain. The effects of this development varies according to the point of view adopted, the parents one or that of the adult children. Though this development increases the probability not to have daughters, there are no clear signs of a weakening of intergenerational ties derived from the development of a beanpole type kin structure. The biggest threat for the density of intergenerational relationships derives not as much from this development, but from the geographical dispersion of the generations caused by the lack of professional and employment opportunities for the younger generations.

    El objeto de este trabajo es analizar los efectos de la caída de la fecundidad sobre los intercambios materiales e inmateriales entre las generaciones (adultas y residentes en hogares independientes en España. El análisis atiende, entre otras variables, al número y a la composición por sexos de la generación más joven, analizando los intercambios entre las díadas hijo varón emancipado / padres e hija emancipada / padres. Los efectos de la caída de la fecundidad y otros cambios familiares asociados a la misma dependen del punto de vista que se adopte, esto es, si se analizan desde el punto de vista de los padres o de los hijos. A pesar de que la caída de la fecundidad aumenta la probabilidad de no tener hijas, no hay signos claros de un debilitamiento de las relaciones intergeneracionales derivadas de la caída de la fecundidad. Las mayores amenazas para la densidad de las relaciones intergeneracionales no derivan tanto de la caída de la fecundidad, como de la dispersión de las generaciones como consecuencia de la ausencia de expectativas laborales y profesionales para la generación más joven en

    Full Text Available El objetivo de este trabajo es discutir la importancia de los estudios de arqueología terrestre y subacuática como parte de un mismo proceso de interpretación del pasado. Se entiende que el registro arqueológico puede hallarse actualmente en una variedad de ambientes tanto terrestres como subacuáticos a causa de varias razones, como por ejemplo las oscilaciones de los niveles de agua ocurridas entre el Pleistoceno Final y el Holoceno Medio. Por lo tanto, se propone que para su recuperación debe utilizarse una metodología adaptada al medio ambiente en el cual se encuentre. En este sentido, es importante la interpretación integral del paisaje para acceder a la comprensión de la diversidad ambiental en la que se puede emplazar un sitio arqueológico, y en consecuencia poder “bucear” un registro integrado.

Corrigen como disgrafía la transferencia de la conciencia fonológica al alfabeto. Este problema sería menos complejo si aún contáramos con dos únicos códigos, los tradicionales oral y escrito. Pero en el siglo XXI la situación se torna más difícil, puesto que emergen inéditos códigos, como el Chat y los mnsg de txt. En consecuencia, presumimos que a la escuela se le acumulan las tareas. Concluimos sugiriéndole a la escuela que no juzgue como monstruosos enemigos los emergentes modos de comunicación, sino que trabaje en función de su distinción y utilidad.At the school level is common practice to qualify as dysgraphia the following structures: nadien, argo, unifolme, calsado, bamo.

But in the twenty-first century, the situation becomes more difficult, as it emerge unpublished codes, such as chat and mnsg of txt. Accordingly, we assume that the school is accumulating tasks. We conclude by suggesting that the school does not deem as monstrous enemies the emerging modes of communication, instead of that they should work on the basis of their usefulness and distinction.

    2015-11-01

    This paper presents an efficient constant-time bilateral filter that produces a near-optimal performance tradeoff between approximate accuracy and computational complexity without any complicated parameter adjustment, called a compressive bilateral filter (CBLF). The constant-time means that the computational complexity is independent of its filter window size. Although many existing constant-time bilateral filters have been proposed step-by-step to pursue a more efficient performance tradeoff, they have less focused on the optimal tradeoff for their own frameworks. It is important to discuss this question, because it can reveal whether or not a constant-time algorithm still has plenty room for improvements of performance tradeoff. This paper tackles the question from a viewpoint of compressibility and highlights the fact that state-of-the-art algorithms have not yet touched the optimal tradeoff. The CBLF achieves a near-optimal performance tradeoff by two key ideas: 1) an approximate Gaussian range kernel through Fourier analysis and 2) a period length optimization. Experiments demonstrate that the CBLF significantly outperforms state-of-the-art algorithms in terms of approximate accuracy, computational complexity, and usability. PMID:26068315

  14. La flexibilidad laboral: significados y consecuencias Labour Flexibility: Meanings and Consequences

    Los objetivos del articulo son 1 analizar las consecuencias de la flexibilidad laboral en el curso vital de los individuos, 2 asi como saber si la flexibilidad ha socavado o reforzado la importancia de las clases sociales, de la educacion y del genero en distintos aspectos concernientes al curso vital, sobre todo relacionados con el empleo en Espana. La peculiaridad espanola con respecto a la flexibilidad radica en la alta proporcion de contratos temporales. La mayor diferencia entre estos contratos y los indefinidos es su menor coste de despido. La manera en la que el Estado del Bienestar ha introducido la flexibilidad ha logrado un equilibrio de riesgos entre generaciones, por lo que no puede decirse que haya unos claros ganadores o perdedores. Los datos indican que los efectos de la flexibilizacion sobre el curso vital de los individuos son mucho mas modestos de lo que las hipotesis preven. Asimismo, la flexibilización no ha mermado la importancia de las clases sociales ni de los niveles de estudio para explicar la posición de los individuos en el mercado laboral, aunque tampoco hay una clara evidencia de que las brechas entre los individuos de distintas clases ocupaciones o con distintos niveles de estudio hayan aumentado en Espana.

    The objectives of the paper are 1 to analyse the effects of labour flexibility on individuals from a lifecourse perspective and 2 to know whether flexibility has undermined or reinforced the effects of social classes, education and gender on several aspects concerning the life-course, above all those related to employment in Spain. The peculiarity of the Spanish case lies in the proportion of fixed-term contracts. The greatest difference between these contracts and permanent contracts is not the job to be done, or even its temporary or permanent nature, but rather the lower layoff cost. The way that the Welfare State has introduced flexibilisation has achieved a balance of risks between the generations

  15. Consecuencias personales en la ruptura de la vida laboral. El caso de Telefónica.

    Full Text Available Desde mediados de los años setenta, el mundo del trabajo de los países occidentales comienza a cambiar progresivamente en su estructura y fisonomía. En los últimos años, como consecuencia de la búsqueda de competitividad y la política de fusiones y adquisiciones llevada a cabo en España por algunas grandes empresas, han aumentado de forma significativa las reducciones de plantilla. Considerando que estamos ante un proceso cultural de las sociedades contemporáneas y siendo parte integrante de ese colectivo, cada día más numeroso, de personas desvinculadas del trabajo remunerado a una edad temprana, estudié qué supone este hecho para un grupo de trabajadores de Telefónica. Esta empresa está llevando a cabo la mayor regulación de empleo de nuestro país; terminará 2007, por un plan iniciado en 1993, con una plantilla reducida en un 66 %. Para analizar cómo afecta este hecho a los trabajadores y en qué ámbitos, aspectos y dimensiones de su vida, tuve en cuenta las diferencias de interpretación de sus experiencias en cuanto al tiempo, al espacio y a la sociabilidad. También consideré las diferencias individuales: género, situación familiar, formación, trayectoria laboral, puesto que se ocupaba en la empresa, estrategias de ocupación del tiempo de ocio, etc. A partir de la etnografía se concluye que, siendo la actividad laboral remunerada un factor de identidad personal y social, un factor de integración y estructuración del ser humano, desde una perspectiva antropológico-social, la ruptura de dicha trayectoria, a una edad temprana y de forma brusca y no deseada, conlleva la necesidad de ajuste en todas las actividades del ser humano.

    Testicular epidermoid cysts are the most common benign tumors of the testes, but account for only 1-2% of all testicular tumors. In a young man presenting with a testicular mass, a high index of suspicion must be maintained for the malignant testicular germ cell tumor, which is 50-times more common than testicular epidermoid cyst. Bilateral testicular epidermoid cysts are a very rare condition, with only a few reports in the literature. It is extremely important in this condition to make a co...

    In this article we define the classes of bilateral and multivariate bilateral matrix-exponential distributions. These distributions have support on the entire real space and have rational moment-generating functions. These distributions extend the class of bilateral phasetype distributions of [1......] and the class of multivariate matrix-exponential distributions of [9]. We prove a characterization theorem stating that a random variable has a bilateral multivariate distribution if and only if all linear combinations of the coordinates have a univariate bilateral matrix-exponential distribution.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    International Nuclear Information System (INIS)

    In the Russian Federation, serious consideration is being given to the safety of nuclear facilities and to security of nuclear material. One important factor in ensuring security of nuclear material and facilities is physical protection. The Ministry of Atomic Energy of the Russian Federation is making great efforts to improve physical protection of nuclear facilities. Some of the measures which are being implemented to improve physical protection are being carried out in the framework of international co-operation in this field. To date, the Russian Federation has established bilateral co-operation with the United States of America, Germany, Belgium, France and Finland, and has studied and taken account of the experience of foreign countries in the field of physical protection and nuclear material accounting and control. At present, over 20 enterprises of the Ministry of Atomic Energy of the Russian Federation representing all the main branches of the nuclear activities of the Ministry are involved in international co-operation on physical protection and nuclear material accounting and control. The main branches of this co-operation are as follows: Scientific and technical co-operation; production of a conceptual design to improve physical protection systems directly at nuclear risk facilities; swift improvement of physical protection (without developing design documentation for the nuclear risk facility as a whole); reinforcement of physical protection during the transport of nuclear material; and training of staff at nuclear risk facilities. During this work, many facilities were equipped with modern physical protection and with nuclear material accounting and control equipment. The Ministry of Atomic Energy of the Russian Federation is pleased with the results of this international co-operation and feels that it should continue. (author)

    Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

    Objective Report on the 7-year experience with bilateral ophthalmic artery chemosurgery (OAC-Tandem therapy) for bilateral retinoblastoma. Design Retrospective, single institution study. Subjects 120 eyes of 60 children with bilateral retinoblastoma treated since March 2008. Methods Retrospective review of all children treated at Memorial Sloan Kettering with bilateral ophthalmic artery chemosurgery (Melphalan, Carboplatin, Topotecan, Methotrexate) delivered in the same initial session to both naïve and previously treated eyes. Main Outcome Measures Ocular survival, metastatic disease, patient survival from metastases, second cancers, systemic adverse effects, need for transfusion of blood products, electroretinogram before and after treatment. Results 116 eyes were salvaged (4 eyes were enucleated: 3 because of progressive disease, 1 family choice). Kaplan Meier ocular survival was 99.2% at one year, 96.9% at 2 and 3 years and 94.9% for years 4 through 7. There were no cases of metastatic disease or metastatic deaths with a mean follow-up of 3.01 years. Two children developed second cancers (both pineoblastoma) and one of them died. Transfusion of blood products was required in 3 cases (4 transfusions), 1.9%. Two children developed fever/neutropenia requiring hospitalization (0.95%). ERGs were improved in 21.6% and unchanged after treatment in 52.5% of cases (increase or decrease of less than 25μV). Conclusions Bilateral ophthalmic artery chemosurgery is a safe and effective technique for managing bilateral retinoblastoma-even when eyes are advanced bilaterally, and if both eyes have progressed after systemic chemotherapy. Ocular survival was excellent (94.9% at 8 years), there were no cases of of metastatic disease and no deaths from metastatic disease, but children remain at risk for second cancers. In 21.6% of cases ERG function improved. Despite using chemotherapy in both eyes in the same session, systemic toxicity was low. PMID:27258771

    STALE EINARSEN

    2006-01-01

    Full Text Available El presente artículo revisa y resume la investigación y la literatura sobre el concepto de acoso psicológico en el trabajo, su naturaleza, consecuencias, y antecedentes. El acoso psicológico en el trabajo hace referencia a conductas negativas continuadas que son dirigidas contra uno o varios empleados por sus superiores y/o colegas. Alrededor del 1-10% de los trabajadores están expuestos a comportamientos de acoso. El acoso puede conducir a problemas emocionales y psicosomáticos, a un menor bienestar en las víctimas, y a un incremento en el absentismo y la rotación en las organizaciones. Se han propuesto como posibles antecedentes del acoso psicológico en el trabajo desde las características de personalidad hasta los factores organizacionales. Se ha encontrado que los individuos introvertidos, neuróticos y sumisos tienen mayor probabilidad de ser acosados. Se han investigado una amplia variedad de posibles estresores del entorno laboral en relación con el acoso psicológico, siendo las deficiencias en el liderazgo y el diseño del trabajo los factores que propician el acoso. Del mismo modo, existe una atención creciente hacia los cambios en la naturaleza del trabajo, donde los cambios organizacionales y el incremento de la incertidumbre han sido estudiados en relación con el acoso. Aunque se necesita mayor investigación en esta área, existe suficiente evidencia para afirmar que la mayoría de las organizaciones deberían esforzarse en la prevención y el manejo de este problema.

    2006-10-01

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

  15. Barrios cerrados como estrategia de desarrollo municipal

    Full Text Available Los barrios cerrados han sido generalmente estudiados desde la perspectiva de sus residentes, preferencias, estatus económico, y ambiciones sociales. Aun más, estos proyectos han sido asociados con el debilitamiento del estado y un desarrollo urbano gobernado por las necesidades del mercado. Sin embargo, queda por responder cual ha sido el papel de las instituciones públicas en la proliferación de barrios cerrados. Este artículo analiza el caso de Buenos Aires, donde las municipalidades suburbanas más pobres han visto a las urbanizaciones cerradas como una estrategia de desarrollo local. Aprovechando la descentralización de la reglamentación sobre los usos del suelo del nivel provincial al municipal, las municipalidades con un alto porcentaje de hogares pobres han facilitado el desarrollo de urbanizaciones cerradas como estrategia para aumentar el empleo local y la inversión privada en la zona. Como consecuencia de esta política, las urbanizaciones cerradas se han concentrado en las municipalidades más pobres del cono urbano bonaerense. Así, se ha incrementando la polarización social dentro de cada municipalidad, lo cual llama a revisar el efecto de las reformas de descentralización en la formación de una sociedad mas inclusiva y participativa.

  17. Concomitant bilateral testicular epidermoid cysts

    International Nuclear Information System (INIS)

    Epidermoid cyst of the testis is a rare benign germ tumor, comprising 1-2% of all resected benign testicular masses. Approximately 300 cases have been reported to date. Unilateral involvement has often been reported in the English literature. However, bilateral occurrence is very rare and to the best of our knowledge, there only 3 previous reports of bilateral testicular epidermoid cysts. The fact that they are completely benign makes them amenable to treatment by local excision, thereby saving patient from orchidectomy. Recognition of their characteristic ulatrsonographic features is very important to avoid unnecessary intervention. We present here, a case of bilateral epidermoid cyst in which characteristic ultrasound (US) findings allowed testis-sparing enucleation instead of radical orchiectomy. (author)

    This paper is a short introduction to how the sinusoidal voltage waves are generated. A revision is made on the way of representing a distorted wave and the way of quantifying its harmonics content (harmonics distortion). An overview is made of the non-lineal consuming elements that produce distortion of the current waves. A revision is made on the concept of a power factor in conditions of waves with harmonic distortion. The consequences of feeding with distorted waves the different devices such as motors (particularly for the distortion originated by the rectifiers and the velocity electronic controls), transformers and capacitors. Mention is made of some of the methods for not to produce or for reducing the harmonic effect in the electric networks. The purpose of this article is to review the consequences on energy consumption by the presence of harmonics. [Espanol] En este articulo se hace una breve introduccion de la forma en que se generan las ondas senoidales de voltaje.

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

    Full Text Available Objetivos: Los resultados de diversos estudios sugieren la existencia de un período crítico en el desarrollo del individuo en el cual la experiencia de maltrato y abuso sexual puede conllevar cambios neurobiológicos permanentes o muy duraderos, afectando especialmente a la respuesta del eje neuroendocrino hipotálamico-hipofisario-adrenal. El objetivo de este trabajo es ofrecer una revisión actualizada de las principales consecuencias neurobiológicas del abuso sexual infantil. Métodos: Se seleccionaron aquellas publicaciones de enero de 1999 a enero de 2010, en inglés o español, centradas en las consecuencias neurobiológicas relacionadas con la experiencia de abuso sexual infantil mediante las bases de datos Medline, Scopus, Psycinfo y Web of Science. También se examinaron las listas de referencias de estudios publicados acerca de las consecuencias neurobiológicas de la victimización en la infancia. Resultados: Se incluyeron 34 estudios sobre consecuencias neurobiológicas del abuso sexual infantil, de los cuales se extraen alteraciones neuroendocrinas, estructurales, funcionales y neuropsicológicas que afectan a un importante número de víctimas. Conclusiones: Los trabajos que hasta ahora han explorado los efectos neurobiológicos del maltrato muestran que es necesario considerar a éste y al abuso sexual infantil como problemas de salud que afectan a diferentes áreas de la vida de sus víctimas, favoreciendo así el desarrollo de programas de intervención y tratamiento teniendo en cuenta sus múltiples efectos.Objective: The results of several studies suggest that there is a critical timeframe during development in which experiences of maltreatment and sexual abuse may lead to permanent or long-lasting neurobiological changes that particularly affect the hypothalamus-pituitary-adrenal axis response.

Se puede afirmar que ésta actualmente se rige por los Objetivos del Milenio y los establecidos en el «Programa de Educación para Todos», incorporando poco a poco el concepto del Desarrollo Humano Sostenible, dando cabida a la diversidad cultural como un aspecto sustancial de la sostenibilidad. Estos planteamientos teóricos tienen consecuencias directas en los programas y proyectos de cooperación educativa. A grandes rasgos, destacan iniciativas de educación intercultural y propuestas que priorizan la revalorización de las culturas, gozando de características comunes pero también de relevantes rasgos diferenciadores. Establecer estos encuentros y desencuentros será el objeto de este trabajo, con el propósito de aportar diversas perspectivas para la cooperación educativa internacional ante el reto actual de la sostenibilidad cultural y ambiental.Diverse reflections have been taken place around the concepts of culture and development during the present century, which have revealed deep influence on the International Cooperation in Education. Nowadays there is no doubt that this issue is governed by the so called Millenium Aids, and by those objectives such as the ones established in the «Programof Education for All». These two frames have gradually incorporated the concept of Sustainable Human Development, allowing the cultural diversity become a substantial aspect of sustainability.These theoretical reflections have direct consequences on the programs and projects involved in the Cooperation in Education. Broadly speaking, it can be stated that intercultural educational initiatives and proposals, while they have the revaluation of cultures as main priority, they both share common characteristics and reveal relevant differences.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth.

    Macrodontia is a rare dental anomaly that refers to teeth that appear larger than normal. Generalised macrodontia can be associated with certain medical conditions and syndromes. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 14-year-old child. The patient was referred to the clinic with local crowding of maxillary and mandibular teeth. Radiographic findings revealed the presence of impacted macrodont mandibular second premolar on one side and erupted macrodontic premolar on the other side and their distinct morphological appearance, characterized by large, multitubercular, and molariform crowns and tapering, single roots.

    Full Text Available Este artículo demuestra la incidencia del conflicto armado colombiano en la desarticulación del movimiento sindical. Se observa cómo en los últimos años la tasa de trabajadores sindicalizados por esa razón ha disminuido significativamente; no en vano distintas investigaciones afirman que nuestro país es el más peligroso del mundo para ejercer la actividad sindical. De igual forma, se esboza una posible responsabilidad estatal por la implementación de políticas antisindicales, y se desarrolla la que, a nuestro juicio, constituye la principal consecuencia de esta situación: la disminución de procesos serios de negociación colectiva que utilicen este mecanismo en forma idónea para repartir equitativamente las garantías de solución al conflicto colectivo y los sacrificios necesarios por parte de cada uno de los actores de la relación laboral.

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

    2013-01-01

    Full Text Available Bilateral ovarian tumour in a girl presents the dilemma of conservative versus aggressive approach towards these tumours. When faced with suspicious tumour and complete replacement of the ovaries bilaterally, bilateral oophorectomy is a viable option, though the certain possibility of infertility and lifelong hormonal supplementation is unavoidable. We report a case of bilateral ovarian masses in a young girl, which on histopathological examination showed mature teratoma with aggregates of proliferating capillary and cavernous sized vessels in the tumour wall. Such associations are rare and must be differentiated from a vascular neoplasm.

Clinical findings and complementary studies suggested a bilateral atherogenic embolic event. Initially, she presented a superior branch retinal artery occlusion in her right eye followed by a central retinal artery occlusion with cilioretinal artery sparing in her left eye. Some conservative maneuvers performed did not improve visual acuity in the left eye. Supra-aortic Doppler ultrasonography revealed mild right internal carotid artery stenosis and moderate left internal carotid artery stenosis with a small, smooth, and homogeneous plaque. The transthoracic echocardiography showed a severe calcification of the mitral valve with a mild-moderate rim of stenosis. Central retinal artery occlusion and branch retinal artery occlusion are characterized by painless monocular loss of vision. Clinical approach and management attempt to treat the acute event, find the source of the vascular occlusion, and prevent further vascular events from occurring. Giant cell arteritis is a potentially treatable cause of central retinal artery occlusion and should be excluded in every single patient over 50 years old.Keywords: loss of vision, branch retinal artery occlusion, central retinal artery occlusion, Hollenhorst plaque

    Full Text Available En el presente trabajo se exponen algunas consideraciones sobre diferentes procesos productivos y sus consecuencias sobre el medio ambiente. La disminución del impacto negativo de algunas producciones sobre el medio ambiente es favorable, pero el problema va más allá y de lo que se trata es de la necesidad de una transformación sostenible de las producciones que puedan conducir a una vida agradable y una naturaleza conservada entre otras muchas cuestiones que agobian hoy al mundo. La solución al problema puede ser alcanzada con mayor prioridad en la reducci ón de la fuente primaria de la contaminación, seguida por el reciclaje y el desarrollo de tecnologías limpias. La reducción en la fuente se aplica por los cambios de productos y procesos. El cambio de la fuente se relaciona con la composición o el uso de los productos intermedios y finales, que reduzcan los residuos de producción, su uso o la disposición de los productos. Los cambios de procesos están relacionados con la sustitución de las materias primas de entrada, la modificación de las tecnologías y las mejoras operacionales. Las opciones específicas pueden incluir: el uso de materiales menos tóxicos, el aumento de la automatización, los procedimientos para las operaciones y el mantenimiento, el control de inventario, entre otros.

    Full Text Available In the early twentieth century, the Republican political restructuring in Colombia involved the predominance of government civil buildings over the religious (inherited from colonial rule. However, the largest architectural work in Ibague was the Carmelite church. This dilemma led to the investigation of notarial sources, photographic and cartographic collections, which obtained data were then compared to understand the relationship between architecture and the underlying social dynamics. Thus, was discovered the political, educational and religious structure which intervened in the architectural realization of ideas of that time, consistent that the government delegated in the religious orders the educational tasks necessary for national development, amalgamating political and educative trends with religious, to generate a strategy which publicized the architecture as a symbol of economic development.

Un adulto de B. constrictor, ingresó con mucosas congestionadas, presencia de tierra en la cavidad oral, ulceraciones gingivales, deshidratación marcada y tegumento reseco con retención de muda. Presentó además letargia con postura anómala de la cabeza, con leve aumento de tamaño a nivel dorsal y antecedente de trauma. Se observó anemia no regenerativa y leve monocitosis relativa. Los hallazgos radiográficos fueron compatibles con fractura parietal e inflamación del tejido blando circundante. Se estabilizó el paciente y se realizó lavado bucal y debridación, posteriormente se administró tratamiento antibiótico y analgésico. La evolución no fue satisfactoria y terminó con la muerte del animal. El diagnóstico final fue una severa neumonía supurativa necrotizante de origen bacteriano posiblemente por Pasteurella o Pseudomona, con SE secundaria.

    Full Text Available From year to year, an ever increasing number of young professionals with good postgraduate training enter the labor market in Spain. The author discusses the consequences that this economic and sociological trend has for young and oíd workers in the two-fold context of high flexibility of labor markets and frequent, computer-related, technological innovations. While new employees must deal with highly unstable and competitive labor markets, older workers may simply lose their jobs to young replacements. Governments cope with this situation either by reducing the age for retirement (e.g., in Spain and Europe or by helping oíd people accept a second professional opportunity (e. g., in the USA.En los últimos años, son tantos los jóvenes universitarios españoles con buena formación de posgrado y el deseo de un puesto de trabajo satisfactorio que desbordan la capacidad del sistema económico de absorberlos. Las consecuencias de este desfase son diversas, pero en este trabajo se llama la atención sobre la competencia que se da entre los jóvenes empleados, que ha dado lugar a unas condiciones de trabajo leoninas en lo que respecta a horario y a estabilidad en el empleo. Estas condiciones han generado una gran presión sobre los trabajadores de mayor edad, hasta el punto de poner en peligro el mercado laboral para este sector de la población. Sin embargo, en los Estados Unidos la participación de los trabajadores entre 55 y 65 años en la población activa apenas ha descendido en los últimos quince años, lo que supone la existencia de lo que genéricamente se podría llamar «la segunda oportunidad», una opción contrapuesta a la de las prejubilaciones, que parece la opción de España y Europa.

The diagnosis was a little confusing as he initially presented with features suggestive of retrobulbar hemorrhage secondary to his very low platelet count, which is a common feature of dengue fever. Ophthalmic complications are usually seen in young adults who often present at the nadir of thrombocytopenia. Ocular findings may include anterior uveitis, vitritis, retinal hemorrhages, retinal vascular sheathing, yellow subretinal dots, retinal pigment epithelium (RPE mottling, foveolitis that is clinically seen as a round subretinal yellowish lesion at the fovea, retinochoroiditis, choroidal effusion, optic disc swelling, optic neuritis, neuroretinitis, and oculomotor nerve palsy. [1] There is only one reported case of unilateral endogenous panophthalmitis due to dengue fever. Hence, clinicians and ophthalmologists have to be aware of this vision-threatening complication of dengue for early recognition and prompt treatment to save the vision of these young patients and prevent morbidity.

  1. Bilateral symmetry across Aphrodite Terra

    International Nuclear Information System (INIS)

    There are three main highland areas on Venus: Beta Regio, Ishtar Terra and Aphrodite Terra. The latter is least known and the least mapped, yet existing analyses of Aphrodite Terra based on available Pioneer-Venus orbiter data suggest that it may be the site of extensive rifting. Some of the highest resolution (30 km) PV data (SAR) included most of the western half of Aphrodite Terra. Recent analysis of the SAR data together with Arecibo range-doppler topographic profiling (10 X 100 km horizontal and 10 m vertical resolution) across parts of Aphrodite, further characterized the nature of possible tectonic processes in the equatorial highlands. The existence of distinct topographic and radar morphologic linear discontinuities across the nearly east-west strike of Aphrodite Terra is indicated. Another prominent set of linear features is distinctly parallel to and orthogonal to the ground tracks of the PV spacecraft and are not included because of the possibility that they are artifacts. Study of the northwest trending cross-strike discontinuities (CSD's) and the nature of topographic and morphologic features along their strike suggest the presence of bilateral topographic and morphologic symmetry about the long axis of Aphrodite Terra

    2009-08-01

    Full Text Available Leptospirosis is a zoonosis of worldwide occurrence caused by the spirochete Leptospira interrogans. It is an acute feverish disease with a broad clinical spectrum and follows a characteristic biphasic course. Bilateral facial palsy is a rare clinical condition and the differential diagnosis of its causes is extensive. The objective of this exploratory study, presented as a case report, is to describe the occurrence of bilateral facial palsy as an unusual manifestation of leptospirosis. This suggestion should not be overlooked when analyzing the causes for bilateral facial palsy, and should be considered with other possible differential diagnoses, some of which are potentially fatal.

    Full Text Available Trade between Colombia and Venezuela has been totally affected in the past four years. One of the salient features is evidenced by the records of imports and exports of billions of dollars that experienced their peak in 2008 with 7.289 million dollars of trade. However, since 2009 this trade declined due to political confrontations that made to rethink the challenges and strategies in Caracas and Bogota to recover, rather than economic, the political, institutional and even social. This research aims to analyze the causes that led to a stage where it is ob-served a booming in bilateral trade, momentum, maximum and steep drops, but one way or another are needed for its complement. The methodology used in this study was the documentary research. Finally these events are related to the rigors of exchange control in Venezuela, CADIVI, that affect the price of the products that are recorded daily in various transactions made by entrepreneurs and marketers on the Colombian side and by the end 2011 recorded an exchange of 2,193 million.El intercambio comercial entre Colombia y Venezuela ha estado totalmente afectado en los últimos cuatro años.

  10. FLOWING BILATERAL FILTER: DEFINITION AND IMPLEMENTATIONS

    2015-06-01

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

  11. THE EUROPEAN UNION’S BILATERAL APPROACH

    Directory of Open Access Journals (Sweden)

    Ludmila BORTA

    2014-12-01

    Full Text Available The EU is a world economic power and a major trading partner for most countries. All the time, this region has been interested and has acted towards a free and fair trade. The decrease and even the elimination of tariff and non-tariff barriers in the world trade are among the main objectives of the EU strategy for international trade. At the moment, the elusive outcome of the WTO Doha Round has led to the proliferation of bilateral trade agreements worldwide. Although the EU remains committed to further development of the multilateral trading system, however, the EU still has appealed also to the development of bilateral trade relations. The aim of this paper is to illustrate the current bilateral dimension of the common commercial policy of the EU. In conclusion, to describe this bilateral approach of the EU we are using one word, namely “diversity”.

    Lipoma arborescens is a rare disease that has generally been considered to be unilateral. We report a case of bilateral disease in a patient with associated marked premature osteoarthritis of the knees. We postulate a possible association between these two conditions and explain a possible underlying mechanism. We suggest that lipoma arborescens be considered as a rare underlying cause of young patients with bilateral premature osteoarthritis, and recommend MRI as the definitive imaging modality. (orig.)

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

    Full Text Available In bilateral thumb amputations, the functional impairment is serious and every attempt should be made to reconstruct the thumb. We report a case of bilateral post traumatic thumb amputation, reconstructed with bilateral second toe transfer. Only two such cases have been reported in literature so far. Though there are various modalities for the reconstruction of thumb, microvascular toe transfer has its own merits. The convalescent period is minimal with excellent function. It is bilaterally symmetric and aesthetically superior to the osteoplastic reconstruction. The technical details are discussed, and the long term functional and aesthetic results are presented.

    Full Text Available Este artículo tiene como propósito construir y validar un modelo integrado de relaciones para el fomento de la creación de valor percibido por los egresados en el ámbito universitario. Con esta finalidad, se aplican las directrices del marketing de relaciones al análisis de la gestión educativa y al encuentro de servicio entre el profesor y sus estudiantes, mediante un estudio de campo realizado a 1000 egresados universitarios de dos universidades españolas. La técnica empleada fue el análisis factorial confirmatorio y el contraste del modelo estructural planteado a nivel teórico, con LISREL 8.80. Las conclusiones de este estudio suponen un avance en la literatura sobre educación superior, al corroborarse las relaciones planteadas, escasamente analizadas en este ámbito con anterioridad. Así, los resultados muestran que variables como la confianza, la calidad de la interacción alumnoprofesor, y la imagen de la Universidad influyen positivamente en la percepción del valor que ésta aporta, el cual, a su vez, afecta al nivel de satisfacción del egresado, contribuyendo a la formación de lealtad hacia la institución.

    Full Text Available En este artículo presentamos el concepto de vida humana como texto eterno en el pensamiento de Ortega y sus consecuencias para el problema de la interpretación. La filosofía de la razón vital de Ortega se fundamenta en el concepto de vida humana como realidad radical y principio interpretativo universal, y por esta razón se presenta desde el principio como una filosofía hermenéutica de la vida y no como una reducción hacia la conciencia trascendental. Esta hermenéutica se practica especialmente en el ámbito del arte. Pero para Ortega todo texto es hermenéutico y necesita por tanto la interpretación, porque ningún texto posee en sí mismo su verdad.

    In Brazil electricity is traded through three segments: the spot market that balances offer and demand, with prices calculated by a cost-based computational model; the regulated market , where prices are settled in public auctions, and the free market for bilateral contracts. As spot and regulated market prices are public information, a seller is able to calculate his opportunity price to trade a bilateral contract in the free market by using the non-arbitrage principle. Thus, the seller searches the price of a bilateral contract in the free market that balances his/her revenues with the value expected in case it were negotiated in the regulated and the spot market. Besides the expected revenue, the seller may also consider the CVaR to measure the risk of her/his bilateral contract in the free market. So this paper develops a binomial lattice approach to price bilateral contracts in the free market, considering the seller's opportunity of negotiations in both regulated and spot markets, and measuring the contract risk directly.

  12. Chronic Bilateral Tibial Stress Fractures with Valgus Treated with Bilateral Intramedullary Nailing: A Case Report

    Directory of Open Access Journals (Sweden)

    Steven K Dailey

    2014-01-01

    Full Text Available Introduction: Stress fractures are overuse injuries most commonly seen in athletes, military recruits, and individuals with endocrine abnormalities. It has been demonstrated that chronic cases of anterior tibial stress fractures refractory to conservative management respond well to intramedullary nailing. To our knowledge, only one report has been published concerning patients with bilateral tibial stress fractures treated with bilateral intramedullary nailing. All patients in the series were high-level athletes. We present the case of a non-athletic patient with chronic bilateral tibial stress fractures and associated deformity successfully treated with bilateral intramedullary nails. Case Report: A 23-year-old Caucasian female full-time student presented with chronic bilateral shin pain for approximately five years. She had failed an extensive regimen of conservative management. She was diagnosed with chronic bilateral tibial stress fractures based on history, physical examination, and radiologic findings. She subsequently underwent sequential intramedullary nailing of her tibiae. Both tibiae were in valgus alignment; however, this did not preclude nail placement. The nails deformed upon insertion into the sclerotic canals to conform to the deformation. Post operatively the tibiae united and patient was relieved of her symptoms. Conclusion: Bilateral intramedullary nailing of chronic bilateral tibial stress fractures should be considered as a treatment option for all patients, not just high-level athletes, who fail a trial of conservative management. Additionally, mild to moderate tibial malalignment does not necessarily preclude tibial nailing as the smaller nails placed in sclerotic canals will likely deform on insertion and conform to the canal. Keywords: Bilateral intramedullary nailing, bilateral tibial stress fractures, valgus

    Currently, no consistent evidence-based guidelines for the management of synchronous bilateral breast cancer (SBBC) exist and it is uncertain how presenting with SBBC affects patients' prognosis. We conducted a review of studies analyzing the association between SBBC and prognosis. The studies that...... reported adjusted effect measures were included in meta-analyses of effect of bilaterality on breast cancer mortality. From 57 initially identified records 17 studies from 11 different countries including 8,050 SBBC patients were included. The quality of the studies varied but was generally low with small...... sample sizes, and lack of consistent, detailed histo-pathological information.

    Full Text Available A 39-year-old male was admitted to our clinic with symptoms of headache, dizziness, nausea, otalgia, otorrhea, tinnitus, and hearing loss in both ears for 3 weeks. Physical examination revealed edema in the tympanic membrane and external ear canal, and pain by palpation in the mastoid area bilaterally. There was no nystagmus, and the rest of the physical examination was otherwise normal. Temporal bone high resolution computed tomography (CT showed a lesion causing erosion in the mastoid cortex, tegmen tympani, ossicles, and in the bone covering the sigmoid sinus bilaterally. There was also erosion in the superior semicircular canal and petrous bone on the left side. Cortical mastoidectomy was performed under general anesthesia. Histopathologic examination of the tissue revealed Langerhans cell histiocytosis (LCH. In this paper a case with LCH, presenting with bilateral mastoid involvement which has been rarely reported in the literature, is discussed with the existing literature.

  15. Bilateral Supernumerary Kidney: A Very Rare Presentation

    International Nuclear Information System (INIS)

    To our knowledge, bilateral supernumerary kidney is a very rare renal abnormality and there are five cases presented in the literature. It is difficult to diagnose supernumerary kidney and clinicians have not detected most cases preoperatively. Laboratory and imaging studies were acquired and carefully examined. The normal laboratory tests were found. Emergency ultrasonography was performed and they revealed no signs of parenchymal abnormality in both kidneys. Serial imaging study including enhanced computed tomography (CT) was performed. An imaging study identified bilateral supernumerary kidney with expanded collecting systems. On each side, significant rotation anomaly was found. In addition, there were two different renal arteries originating from the aorta. This report presents radiological determinations of supernumerary kidney bilaterally in a young man. We think that CT commonly appears to be enough for the diagnosis of supernumerary kidneys

Por ello es muy importante entender bien las posibles conexiones entre los incentivos que proporcionan las distintas políticas de seguro ofrecidas tanto a los jubilados como a los trabajadores empleados y desempleados de edad avanzada. Encontramos que una versión simplificada de la reforma de pensiones de 2011 (sin jubilación anticipada a los 61 ni jubilación parcial es capaz de contener el gasto en pensiones (entre el 20 y el 30 por ciento y posponer sustancialmente la salida del mercado laboral (aumento del volumen de empleo a lo largo de ciclo vital en torno al 1-2 por ciento. Finalmente, analizamos una reforma que, además de los elementos de la reforma simplificada de 2011, permite compatibilizar empleo y pensión y aumenta el premio a pedir la pensión después de los 67. Esta reforma permite aumentar (como producto de la acción voluntaria de los agentes la fuerza laboral entre 1-2 por ciento sin afectar a las finanzas del sistema de pensiones, que podrían mejorar hasta un 2% adicional. One of the challenges of economic policy for the coming years will be to increase the labor force participation of older workers. It is therefore very important to understand the possible connections between the incentives provided by different insurance policies offered both retirees and workers employed and unemployed elderly. We find that a simplified version of the Spanish pension reform of 2011 (no early retirement at 61 or partial retirement is capable of containing pension expenditure (between 20 and 30 percent and substantially delay the exit from the labor market (increased volume of employment along the life cycle around the 1-2 percent. Finally, we discuss a reform that, in addition to simplified elements of the reform of 2011, allows claiming while keeping work and increases the premium

El primer experimento estudió el efecto de un intervalo de retención de 48 h en una tarea de igualación a la muestra que involucró el aprendizaje de relaciones de formas coloreadas a través de una fase de adquisición, una fase de inversión, y después de diferentes demoras, una fase final de prueba. El segundo experimento estudió el efecto del PCD en las dos fases de una discriminación inversa. En el tercer experimento se exploró el efecto de un intervalo de retención de 48h y el PCD en la recuperación espontánea de la discriminación original. Los resultados del experimento 1 demostraron la recuperación espontánea de la discriminación original cuando se presentó un intervalo de retención de 48 h. El experimento 2 demostró que el PCD no tiene efectos en las dos fases de una tarea de discriminación inversa. En el experimento 3 se observó una interacción entre el intervalo de retención y el PCD, en la que el PCD (grupo CD1-48h puede mejorar la recuperación de la respuesta de la primera fase (i. e. aumento de la recuperación espontánea mientras el PCD en la fase 2 (grupo CD2-48h mejoró la persistencia de la fase de inversión (i. e. disminución de la recuperación espontánea.

    The bilateral filter is a non-linear filter that uses a range filter along with a spatial filter to perform edge-preserving smoothing of images. A direct computation of the bilateral filter requires O(S) operations per pixel, where S is the size of the support of the spatial filter. In this paper, we present a fast and provably accurate algorithm for approximating the bilateral filter when the range kernel is Gaussian. In particular, for box and Gaussian spatial filters, the proposed algorithm can cut down the complexity to O(1) per pixel for any arbitrary S . The algorithm has a simple implementation involving N+1 spatial filterings, where N is the approximation order. We give a detailed analysis of the filtering accuracy that can be achieved by the proposed approximation in relation to the target bilateral filter. This allows us to estimate the order N required to obtain a given accuracy. We also present comprehensive numerical results to demonstrate that the proposed algorithm is competitive with the state-of-the-art methods in terms of speed and accuracy. PMID:27093722

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

  9. Scintigraphy of incidentally discovered bilateral adrenal masses

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the patterns of iodine-131 6β-iodomethylnorcholesterol (NP-59) imaging and the correlation with CT-guided adrenal biopsy and follow-up in patients with bilateral adrenal masses. To this end we investigated a consecutive sample of 29 euadrenal patients with bilateral adrenal masses discovered on CT for reasons other than suspected adrenal disease. Adrenal scintigraphy was performed using 1 mCi of NP-59 injected i.v., with gamma camera imaging 5-7 d later. In 13 of the 29 patients bilateral adrenal masses were the result of metastatic involvement from lung carcinoma (5), lymphoma (3), adrenocarcinoma of the colon (3), squamous cell carcinoma of the larynx (1), and anaplastic carcinoma of unknown primary (1). Among these cases the NP-59 scan demonstrated either bilaterally absent tracer accumulation (8, all with bilateral metastases) or marked asymmetry of adrenocortical NP-59 uptake (5). Biopsy of the adrenal demonstrating the least NP-59 uptake documented malignant involvement of that gland in five of five patients. In two patients an adenoma was found simultaneously in one adrenal with a contralateral malignant adrenal mass. In each of these cases, the adenoma demonstrated the greatest NP-59 uptake. In 16 patients diagnosis of adenoma was made on the basis of CT-guided adrenal biopsy of the gland with the greatest NP-59 uptake of the pair (n=4), or adrenalectomy (n=2), or absence of change in the size of the adrenal mass on follow-up CT scanning performed 6 months to 3 years later (n=10).

    Obturator hernia (OH), a rare type of hernia, is associated with high morbidity and mortality. Diagnosis is often delayed as clinical symptoms are typically non-specific. OH is frequently associated with other occult inguinopelvic herniae. Early diagnosis is vital to decrease morbidity and mortality. We report the case of a 75-year-old woman who presented to the surgical outpatients' department with non-specific bilateral groin pain radiating to the thighs. CT of the pelvis demonstrated bilateral OH with no radiological evidence of bowel obstruction. Semiurgent elective laparoscopic total extraperitoneal mesh repair was performed. Intraoperative findings confirmed bilateral obturator herniae as well as incidental bilateral femoral herniae. This case highlights the need for a high index of suspicion for such concomitant hernias that, in the presence of OH, may only be identified intraoperatively. PMID:27113790

    2015-01-01

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

    Full Text Available O artigo tenta demonstrar que todos os textos, mesmo aqueles cuja natureza é teórica, têm alguma forma de narrativa. Nem sempre são personagens que os ocupam, podem ser ideias, mas mesmo assim há um enredo conceitual que se passa. Modernamente, a forma dessa narrativa foi sobretudo o sistema, com a pretensão totalizadora presente, por exemplo, na filosofia de Hegel. Contemporaneamente, porém, a forma do ensaio – surgida ainda na era moderna – ganha destaque por sua forma descontínua de narrar. O objetivo do artigo é apontar que, se o ensaio é uma forma, como explicitaram Lukács, Benjamin e Adorno, ele é também uma forma de narrar – ainda que de narrar conceitualmente objetos da cultura.

    Full Text Available La presión social por constituir una forma indentitaria que sea acorde con el referente biológico es de origen histórico y se encuentra al servicio de prácticas de control y dominación social. Este artículo presenta una discusión sobre el lugar actual de la idea de identidad, especialmente en el plano de la sexualidad. Para esto recurre a la tesis de la filósofa Judith Butler, quien propone desde una visión deconstructivista y post-estructuralista una nueva definición de idenridad en términos de la iteración performativa. La identiclad es entendida entonces como una exigencia de inteligibiliclacl ante la sociedad, la cual limita las posibiliclades de expresión sexual.

    2009-01-01

    Upper extremity hemiparesis is the most common post-stroke disability. Longitudinal studies have indicated that 30-66% of stroke survivors do not have full arm function 6 months post-stroke. The current gold standard for treatment of mild post-stroke upper limb impairment is constraint-induced therapy but, because of the inclusion criteria, alternative treatments are needed which target more impaired subjects. Bilateral arm training has been investigated as a potential rehabilitation intervention. Bilateral arm training encompasses a number of methods including: (1) bilateral isokinematic training; (2) mirror therapy using bilateral training; (3) device-driven bilateral training; and (4) bilateral motor priming. Neural mechanisms mediating bilateral training are first reviewed. The key bilateral training studies that have demonstrated evidence of efficacy will then be discussed. Finally, conclusions are drawn concerning clinical implications based on the reviewed literature. PMID:19517519

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    Full Text Available El artículo de Emmanuel Housset implica un esfuerzo de rehabilitación del concepto «persona» para la filosofía contemporánea y la fenomenología. Para ello el autor busca mostrar cómo poco a poco «persona» tomó otra significación que la de «personaje» o sujeto de derecho. Es en autores como san Agustín y santo Tomás de Aquino que se halla un acceso diferente que pone el énfasis más bien en su carácter relacional y responsivo de la persona, antes que en su dimensión autónoma y autotélica. Tal dimensión aparece, según Housset, junto con la idea de persona como creatura y en oposición a la de individuo racional dueño de sí. La dimensión afectiva, la personalidad despertada por las diversas figuras de la alteridad son algunas de las dimensiones de la persona que examina el autor a partir del examen de la carne, las pasiones, la memoria, la historicidad y el amor alteridad.Emmanuel Housset's paper is an effort to revitalize the concept of 'person' for contemporary philosophy and phenomenology To this end the author looks to show how little by little the understanding of 'person' took on a different meaning to that of 'character' or "right bearing individual". It is in authors such as St. Augustine and St. Thomas Aquinas that a different approach is found, one that puts emphasis on the relational and responsive character of a person, rather than on the autonomous and auto telic dimension. According to Housset, such a dimension appears together with the idea of the person as a creation, and in opposition to the idea of the rational individual, that is his own master. The emotional dimension and the personality that is awoken by the many figures of alterity are some of the dimensions of the person that the author analyzes, based on examining the flesh, passions, memory historicity and love.

    Full Text Available 【Abstract】There is a dearth of case reports de-scribing simultaneous bilateral patellar tendon ruptures in the medical literature. These ruptures are often associated with systemic disorders such as lupus erythematosus or chronic steroid use. The author describes a case of a 24-year-old man who sustained traumatic bilateral patellar ten-don ruptures without any history of systemic disease or steroidal medication. We repaired and reattached the rup-tured tendons to the patella and augmented our procedure with allogeneic tendon followed by wire loop reinforcement. One year after operation, the patient regained a satisfactory range of motion of both knees with good quadriceps strength and no extensor lag. The recurrent microtrauma from a history of intense sports activity and a high body mass index may have played an important role in this trauma event.

    Full Text Available Purpose: To report the clinical, confocal scan, and histopathologic features of Nocardia keratitis in a patient who developed bilateral infection following photorefractive keratectomy (PRK. Case Report: A 23-year-old woman underwent bilateral PRK for low myopia. On postoperative day 3, dense central stromal infiltrates were noticed in both eyes. Empirical antibiotic therapy was initiated which was converted into specific therapy after a definite diagnosis was made based on clinical features and confirmed by confocal scan and histopathologic findings. Clinical and confocal scan features were consistent with the diagnosis of Nocardia keratitis, and topical 2% amikacin eye drops were started. Because of poor response to medical therapy, lamellar keratectomy was performed in both eyes which shortened the treatment course. Histopathologic examination reconfirmed the initial diagnosis. Conclusion: Familiarity with clinical and confocal scan features facilitates early diagnosis of Nocardia keratitis leading to proper management and hence a rapid therapeutic response.

  4. Bilateral Pial siderosis and hearing loss

    International Nuclear Information System (INIS)

    Seven adult patients with bilateral progressive hearing loss (six male, one female; aged 40-74 years) were studied with a high-field strength (1.5-T) magnetic resonance (MR) system after previous negative workup with either air contrast or intravenous contrast medium-enhanced computed tomography (CT). In all instances, the patients showed extensive evidence of pial siderosis outlining the posterior fossa subarachnoid space. The siderosis was manifested (on long repetition time images) as an increasing susceptibility effect (hypointensity) with a prolongation of echo time. The results of this study indicate that a negative CT examination is inadequate in patients with bilateral hearing loss and that when evidence of siderosis is found on MR images, an etiology for prior subarachnoid hemorrhage must be pursued

  5. Bilateral breast cancer after cured Hodgkin's disease

    International Nuclear Information System (INIS)

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

    2015-01-01

    Aspergillus endophthalmitis is a devastating inflammatory condition of the intraocular cavities that may result in irreparable loss of vision and rapid destruction of the eye. Almost all cases in the literature have shown an identified source causing aspergillus endophthalmitis as a result of direct extension of disease. We present a rare case of bilateral aspergillus endophthalmitis. A 72-year-old woman with a history of diabetes mellitus, congenital Hirschsprung disease, and recent culture-positive candida pyelonephritis with hydronephrosis status post-surgical stent placement presented with difficulty opening her eyes. She complained of decreased vision (20/200) with pain and redness in both eyes – right worse then left. Examination demonstrated multiple white fungal balls in both retinas consistent with bilateral fungal endophthalmitis. Bilateral vitreous taps for cultures and staining were performed. Patient was given intravitreal injections of amphotericin B, vancomycin, ceftazidime, and started on oral fluconazole. Patient was scheduled for vitrectomy to decrease organism burden and to remove loculated areas of infection that would not respond to systemic antifungal agents. Four weeks after initial presentation, the fungal cultures revealed mold growth consistent with aspergillus. Patient was subsequently started on voriconazole and fluconazole was discontinued due to poor efficacy against aspergillus. Further workup was conducted to evaluate for the source of infection and seeding. Transthoracic cardiogram was unremarkable for any vegetation or valvular abnormalities. MRI of the orbits and sinuses did not reveal any mass lesions or bony destruction. CT of the chest was unremarkable for infection. Aspergillus endophthalmitis may occur because of one of these several mechanisms: hematogenous dissemination, direct inoculation by trauma, and contamination during surgery. Our patient's cause of bilateral endophthalmitis was through an unknown iatrogenic seed

  8. Frequency and causes of bilateral ocular trauma

    International Nuclear Information System (INIS)

    To determine the frequency and causes of bilateral ocular trauma. All patients coming to the hospital with bilateral eye trauma and requiring admission were recruited into the study. The details of patients demographics, risk factors, ocular examination, treatment offered and final visual acuity were noted and described as frequency and percentages. Out of a total of 1551 patients of hospitalized ocular trauma, 46 (2.9%, 92 eyes) had bilateral ocular trauma. The majority (54.3%) were due to landmine blast injuries followed by dynamite blast in 10.8%, coalmine blast and firearm injury in 6.5% each. Pressure cooker explosion and road traffic accident was the cause in 4.3% each. Gas cylinder and automobile battery explosion, alkali and acid burn, assault and incidental trauma occurred in 2.1%. Sixty three percent were between 16 and 40 years of age. Males were affected in 93.4%. Corneal and / or scleral repair was done in 58.6%, conjunctival and or corneal foreign body removal in 26% and extracapular cataract extraction with intraocular lens implantation in 16.3%. The visual acuity was in the range of 6/60 and perception of light in 54.3%, while in 21.7%, there was no perception of light at the time of admission. Due to severity of injury, the final visual acuity was poor and only 28.2% regained vision between 6/18 and 6/60. In this series, landmine, dynamite and coalmine blasts were the major causes of bilateral ocular trauma. Victims were usually young males. Due to severity of ocular trauma, majority had poor visual outcome. (author)

    The well-known bilateral filter is used to smooth noisy images while keeping their edges. This filter is commonly used with Gaussian kernel functions without real justification. The choice of the kernel functions has a major effect on the filter behavior. We propose to use exponential kernels with L1 distances instead of Gaussian ones. We derive Stein's Unbiased Risk Estimate to find the optimal parameters of the new filter and compare its performance with the conventional one. We show that t...

    Full Text Available ABSTRACT The Determination of the tactics for surgical cataract treatment in the fellow eye in patients with bilateral cataracts did not received any unambiguous solution till now and the periods of operation performance are interpreted differently. The authors analyzed the results of treatment in 486 patients with bilateral cataracts. The authors identified a possible favorable interval between first and second operations in case of bilateral cataract, which was based on the clinical, functional and immunological parameters. Phacoemulsifications with peri-operative antibiotic prophylaxis were carried out not later than 4 days after the operation on the first eye, if there were no complications intra-operatively and in post-operative period in the first eye. Recommended time of surgery in the fellow eye in 114 patients of the main group allowed to reveal high functional results (0.7-1.0 in 90.4% in the first eye and in 85.1% of cases in the fellow eye, that promoted the restoration of binocular functions in 98 % of cases after surgery in the shortest possible time. In all patients of the main group the clear vision at different distances were achieved after surgery with bilateral implantation of multifocal IOLs in both eyes in the maximum shortest time. Selected dates of cataract surgery in both eyes taking into account the general and associated ocular pathology allows to reduce the emotional cost, time and organizational problems in preparation for the operation, adding the benefits of quality of early rehabilitation after surgery in both eyes.

Sin embargo, desde un enfoque sistémico puede verificarse que la gran mayoría de los desastres se origina en los países en desarrollo (entre ellos los latinoamericanos, siendo las pérdidas en ellos significativamente más altas que en los países industrializados. Bajo esta postura los desastres no son sólo naturales sino socio- naturales, enfatizando la estrecha relación de causalidad entre modelos de desarrollo y urbanización y procesos de generación de riesgos, al incrementar la vulnerabilidad de los sectores más desprotegidos. El desastre pone en evidencia así una situación (la pobreza y segregación urbana ya existente, pero no considerada hasta el momento de la catástrofe. Frente a este panorama el desastre aparece como oportunidad que precipita tres catalizadores de políticas habitacionales: tierra, asistencia técnica y financiamiento, incrementando la celeridad y la creatividad de las respuestas. El interrogante que surge es por qué esperar el desastre para ponerlos en marcha, cuando ninguno de ellos es estrictamente dependiente de la situación de riesgo, sino sujeto de luchas de poder.

  9. Bilateral femoral head dysplasia and osteochondritis

    International Nuclear Information System (INIS)

    Multiple epiphyseal dysplasia tarda (MEDT) and spondylo-epiphyseal dysplasisa tarda (SEDT) are genetically transmitted conditions affecting the hips, which may resemble bilateral Legg-Perthes disease (LPD). Misdiagnoses are not uncommon, with serious implications for treatment, prognosis and genetic counseling. An epidemiologic study of MEDT and SEDT in a well-defined population of 453 921 persons in Denmark was performed. A population prevalence of 0.7 per 100 000 inhabitants with SEDT and 4.0 per 100 000 inhabitants with MEDT was found. Distinguishing features between MEDT, SEDT and bilateral LPD based on radiologic findings in the hips, other joints, and spine were ascertained. Bilateral LPD is always asymmetric, exhibits patches of increased density in the epiphyses and often metaphyseal cyst-like changes. No spinal lesion or affection of other joints is present, and the acetabula are normal. In MEDT and SEDT the capital femoral epiphyses are symmetrically flattened, fragmented and uniformly slightly sclerotic. Generalised platyspondyly is a constant finding in SEDT. (orig.)

  10. Multilateral, regional and bilateral energy trade governance

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

  11. Medical Image Denoising Using Bilateral Filter

    Full Text Available Medical image processing is used for the diagnosis of diseases by the physicians or radiologists. Noise is introduced to the medical images due to various factors in medical imaging. Noise corrupts the medical images and the quality of the images degrades. This degradation includes suppression of edges, structural details, blurring boundaries etc. To diagnose diseases edge and details preservation are very important. Medical image denoising can help the physicians to diagnose the diseases. Medical images include MRI, CT scan, x-ray images, ultrasound images etc. In this paper we implemented bilateral filtering for medical image denoising. Its formulation & implementation are easy but the performance of bilateral filter depends upon its parameter. Therefore for obtaining the optimum result parameter must be estimated. We have applied bilateral filtering on medical images which are corrupted by additive white Gaussian noise with different values of variances. It is a nonlinear and local technique that preserves the features while smoothing the images. It removes the additive white Gaussian noise effectively but its performance is poor in removing salt and pepper noise.

    Caudate strokes comprise only a small proportion of all subtypes of strokes. Bilateral caudate infarcts are even rarer and only a few cases have been reported in the literature. We report an 86-year-old woman with bilateral caudate infarcts. She had no past medical history of note. She presented with headache for several days and drowsiness on day of admission. Clinical examination revealed abulia, inability to comprehend or verbalize (acute mutism), right-sided neglect and right-sided hemiparesis. Computed tomographic (CT) scan brain revealed decreased attenuation in both heads of both caudate nuclei with extension across the anterior limb of both internal capsules to involve the lentiform nuclei. Echocardiography showed aortic valve sclerosis, mild mitral and aortic regurgitation and normal left ventricular function. Carotid ultrasound revealed mild stenosis of proximal right internal carotid and left distal common carotid and adjacent proximal internal carotid arteries. She showed initial improvement in the first week, but subsequently had a progressive downward course despite rehabilitation and died 44 days after her stroke. A patient with bilateral caudate infarcts is likely to have poor prognosis for rehabilitation and survival. PMID:10561773

    Image smoothing is a fundamental operation in computer vision and image processing. This work has two main thrusts: (1) implementation of a bilateral filter suitable for use in smoothing, or denoising, 3D volumetric data; (2) implementation of the 3D bilateral filter in three different parallelization models, along with parallel performance studies on two modern HPC architectures. Our bilateral filter formulation is based upon the work of Tomasi [11], but extended to 3D for use on volumetric data. Our three parallel implementations use POSIX threads, the Message Passing Interface (MPI), and Unified Parallel C (UPC), a Partitioned Global Address Space (PGAS) language. Our parallel performance studies, which were conducted on a Cray XT4 supercomputer and aquad-socket, quad-core Opteron workstation, show our algorithm to have near-perfect scalability up to 120 processors. Parallel algorithms, such as the one we present here, will have an increasingly important role for use in production visual analysis systems as the underlying computational platforms transition from single- to multi-core architectures in the future.

  14. Bilateral femoral neck fractures following pelvic irradiation

    International Nuclear Information System (INIS)

    Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but thickness of the internal membrane and thrombogenesis were not recognized. Treatment should be performed according to degree of displacement of fractures. In this case, artificial joint replacement surgery was performed to the side of fracture of this time, because this case was bilateral femoral neck fractures and the patient had received artificial head replacement surgery in the other side of fracture formerly.

  15. Bilateral spontaneous rupture of 'hale' kidneys

    International Nuclear Information System (INIS)

    A rare case of spontaneous bilateral rupture of the kidneys, occurring consecutively over a one-year period in a young male patient with 'hale' kidneys until then, is described. The patient's past history and thorough examination performed do not justify to assign the case under the heading of some of the etiological factors as the underlying cause of spontaneous kidney rupture. The literature survey on spontaneous bilateral non-tumor ruptures of kidneys shows that over a 20-year period, only 3 cases of bilateral spontaneous ruptures have been reported. It is pointed out that panarteritis nodosa followed by hemorrhagic fever with renal syndrome is the commonest underlying cause of such ruptures. Clinically spontaneous ruptures become manifest with emergency condition presenting severe renal colic, impaired to serious general condition, often with acute abdomen and hemodynamic breakdown, and no past history evidence of renal disease or injury. In the initial phase diagnosing is not always easy; it is usually made on the ground of physical examination and the full range of imaging studies used in urological practice and during operative treatment. Emphasis is laid on the fact that the imaging methods are not invariably sufficient to identify the exact etiological factor giving rise to such a severe condition, but nevertheless these methods have an essential practical bearing on diagnosing a rupture.

    Full Text Available Nasolabial cysts are painless, submucosal, non-odontogenic jaw cysts presenting as soft tissue swellings in the maxillary anterior mucolabial fold lateral to midline, leading to elevation of nasal ala. Present case documents bilateral nasolabial cysts in a 69-year-old Asian female patient. In the present case, extraoral swelling of maxillary lip and elevation of nasal ala was observed on right side of the face. Intraorally, soft and fluctuant bilateral cysts were observed. Straw-colored fluid was aspirated from the right cyst. Radiographically, erosion of bone in a "cupping" fashion was observed in the region of left cyst. The cysts were enucleated using intraoral approach. Histopathology of the right-sided cyst revealed a cystic cavity lined by stratified squamous cells along with a few mucosal cells. At few places, stratified squamous and pseudostratified columnar epithelia with many cilia and goblet cells were also evident. Capsule was loosely arranged with fibrous tissue and chronic inflammatory infiltrate. Left-sided cystic specimen showed two or more layered stratified squamous lining epithelium with thin capsule. Diagnosis of bilateral nasolabial/nasoalveolar cysts was confirmed.

  18. A case misdiagnosed as bilateral abducens palsy

    International Nuclear Information System (INIS)

    A 66-year-old male was admitted to our neurosurgical floor because of double vision and gait disturbance. Neurological examinations revealed bilateral 6th nerve palsy with both eyes pointing toward the midline. Initially, using a tentative diagnosis of intracranial mass lesions, especially localized at the base of the skull, computerized tomography of the head, cerebral angiography, orbital venography, and metrizamide CT cisternography were performed; the findings were normal. An orbital CT scan showed an enlargement of the bilateral medial rectus muscles, and the thyroid functions of T3 and T4 and the T3 uptake were all elevated, which was compatible with the diagnosis of Graves' disease. The limitations of both eyeballs were considered to be due not to the 6th nerve palsy, but to the hypertrophy of the bilateral medial rectus muscles. We neurosurgeons should recall Graves' disease as well as intracranial lesions, cerebrovascular disease, and post-traumatic sequelae when examining a patient who presents limitations of external ocular movement.

    Full Text Available This article focuses on issues related to the identification and investigation of the lymph node metastases with bilateral breast cancer. The presence of metastases in the lymph nodes determines the stage of the disease, and introducing a form of tumor progression, characterizes the course and prognosis for the future in a specific patient. Thus, the identification of possible morphological and immunohistochemical characteristics of the tumor tissue and their comparison with the frequency and severity of regional lymph nodes would help to solve the problem of the identification of prognostic factors and markers associated with the risk of nodal metastasis in bilateral breast cancer. This work is relevant due to the fact that the literature on this issue to date are treated ambiguously, and answers to many questions, unfortunately, no.The authors performed a morphological study of the tumor tissue from 600 patients suffering from unilateral and bilateral breast cancer. To avoid false results were studied only cases corresponding to the histological type of invasive carcinoma of non-specific type. The study found that a greater number and a greater percentage of the affected lymph node metastases were observed in patients with bilaterally synchronous tumors. The patients of this group of metastatic lymph nodes was detected more frequently in the presence of infiltrative component of three or more types of structures with the presence of these discrete groups of tumor cells, and the observed maximum degree of inflammatory infiltration of the tumor stroma. In the group of patients with unilateral breast cancer nodal metastasis often detects when triple negative molecular genetic type of the lesion, with large amounts of tumor site, in the presence of infiltrative component of three or more types of structures with the obligatory presence of these microalveolar structures and discretely spaced groups of tumor cells and the highest severity of

    Full Text Available Este estudio ha perseguido dos objetivos fundamentales: encontrar diferentes trayectorias en el consumo de sustancias a lo largo de la adolescencia y analizar las consecuencias que este consumo en la adolescencia temprana y media tiene para el ajuste emocional y comportamental al final de la adolescencia. El estudio, con un diseño descriptivo longitudinal mediante cuestionarios, se llevó a cabo sobre una muestra de 101 adolescentes (63 varones y 38 mujeres que fueron estudiados en 3 ocasiones: a los 13, 15 y 18 años de edad. Los resultados mostraron tres grupos de adolescentes en función de las trayectorias seguidas por su consumo de sustancias: consumo bajo, consumo ascendente y experimentación precoz. La comparación entre estos tres grupos indicó un mejor ajuste psicológico en la adolescencia tardía entre los varones y mujeres del grupo de experimentadores, mientras que los problemas de conducta fueron más frecuentes entre los incluidos en el grupo de consumo ascendente. Por otra parte, los análisis de regresión señalaron que el consumo moderado de sustancias en la adolescencia temprana estaba relacionado con una autoestima más alta y con menos problemas emocionales al final de la adolescencia, pero no con más problemas externos.

We have looked at Law from the viewpoint of society 's need to have basic mies for living together, with the juridical ruZe being one of the most important. We have highlighted the views of Hart and Kelsen on the foundations of the validity of Law. We have also considered the obligatoriness of Law; giving the point of view of tadbruch who, explaining his ''Theory of the Obligatoriness of Law ", concluded that the obligatoriness of Law can only be withdraw when there is a Clash between morals, law, use and social conventions. We have looked at the notion of the imperativeness of Law the central theme of the work -drawing on the views of Miguel Reale, for whom the juridical nonn cannot be reduced to a "command of a volitional nature", but rather the obligatory character of the juridical nonn arises from the pressure of social values. Del Vecchio, who is also quoted, recognized that imperativeness exists in the juridical norm, whether it is preceptive (a positive command or permissive. Also mentioned is the opinion of Tercio Sampaio Ferraz, for whom the juridical norm has imperativeness to the extent that the imposition of behaviour is unconditionally guaranteed.

La literatura al respecto es escasa y en nuestro país prácticamente inexistente. Este artículo pretende explorar las razones por las que los empleados no expresan sus opiniones en el trabajo, así como sus consecuencias, adoptando el formato de revisión bibliográfica. Los empleados se muestran muy interesados en el futuro de su puesto de trabajo, en mantener buenas relaciones y en estar bien considerados. Esto puede provocar inhibición debido a una desvinculación, al miedo o a la cooperación. Todos los artículos utilizados en esta revisión provienen de revistas de economía y gestión inglesas y americanas, lo cual subraya la importante necesidad que estudios que exploren el silencio dentro de la enfermería en España.Silence in the workplace may have important consequences on the decision-making process and it may interfere with the solving-problems ability. There is a lack of evidence explorin this topic. Therefore, this literature review explores the reasons and implications of keeping silent in the workplace. The aim of this paper is to explore the reasons and the implications that silence has within the workplace. Employees are very interested in their workplace’s future, in keeping good relationships, and in being well considered, and it is precisely this position that is making them more inhibited in the workplace. Disengagement, fear and co-operation are the main reasons why people remain silent among employees in the workplace. All the articles used in this paper come from English and American business and management journals. This issue highlights the need of nursing research about the topic of discussion in Spain.

    Full Text Available We present a 54 year old male patient who had a bilateral lung transplant sixteen years ago for Alpha-1 Antitrypsin Deficiency-related emphysema. He was referred for flexible bronchoscopy with transbronchial biopsies to evaluate new mild exertional dyspnea and worsening of his FEV1. Eight transbronchial biopsies were done from the right middle lobe and the right lower lobe. Post procedure he developed bilateral pneumothoces that required emergent bilateral pleural ‘pigtail’ catheters. To our knowledge, this is the first reported case of bilateral pneumothoraces that developed after a unilateral procedure in a bilateral lung transplant recipient relatively late after the transplant.

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

    Lipoma arborescens is a rare cause of chronic monoarticular arthritis. It is most commonly seen in the knees, but only a few cases involving other joints, especially the subdeltoid bursa, have been described. To our knowledge, this is the first reported case of lipoma arborescens involving bilateral subdeltoid bursae. Although it is associated with joint effusion, synovial cysts and erosions, the presence of reactive bone formation has not been reported. Magnetic resonance imaging is a very effective method for the diagnosis of this rare condition because of its ability to do tissue characterization

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A neuralgia do nervo trigêmeo é uma condição intensamente dolorosa, caracterizada por surtos de dor lancinante e súbita, tipo choque, com duração de poucos segundos a dois minutos e geralmente unilateral. Sua incidência anual é de cerca de 4,3 em 100.000 na população geral, tendo manifestação bilateral em apenas 3% desses casos. O objetivo deste artigo foi descrever um caso raro de neuralgia do trigêmeo primário bilateral. RELATO DO CASO: Paciente de 61 anos, maranhense, casada, do lar, com antecedente de hipertensão arterial e há seis anos com queixa de dor intensa em V2-V3 à esquerda, com duração de 5 a 10 segundos, em região lateral do nariz e mandibular, com piora ao falar, mastigar e com diminuição da temperatura. Já havia utilizado clorpromazina (3 mg a cada oito horas e carbamazepina (200 mg a cada oito horas durante seis meses sem alívio da dor. Ao exame físico apresentava alodinia térmica e mecânica em regiões de V2-V3. Estava em uso de gabapentina (1.200 mg ao dia com alívio parcial da dor. Foi então aumentada a gabapentina para 1500 mg ao dia e introduzida amitriptilina 12,5 mg à noite. Evoluiu com dor leve e esporádica com diminuição da intensidade da dor ao longo de 10 meses de tratamento, sendo reduzida progressivamente a gabapentina para 600 mg ao dia e mantida a amitriptilina 12,5 mg ao dia. Após um ano, começou a apresentar dor de característica semelhante em região mandibular à direita, tendo melhorado com aumento de gabapentina para 900 mg ao dia. Não apresentava exames alterados de tomografia ou ressonância magnética de encéfalo. CONCLUSÕES: A carbamazepina é o fármaco de primeira escolha para tratamento de neuralgia trigeminal, porém a gabapentina tem sido cada vez mais utilizada como primeira medida farmacológica ou em casos refratários à terapia convencional.JUSTIFICATIVA Y OBJETIVOS: La neuralgia del nervio trigémino es una condici

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl(-1) and aldosterone renin activity ratio of 90.2 (ng dl(-1) per ng ml(-1 )h(-1)), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl(-1) confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

  2. Bilateral based robust load frequency control

    International Nuclear Information System (INIS)

    Load frequency control (Lc) has been one of the major subjects in electric power system design/operation and is becoming much more significant today in accordance with increasing size and the changing structure and complexity of interconnected power systems. In practice, power systems use simple proportional-integral (PI) controllers for frequency regulation and load tracking. However, since the PI controller parameters are usually tuned based on classical or trial and error approaches, they are incapable of obtaining good dynamical performance for a wide range of operating conditions and various load changes scenarios in a restructured power system. This paper addresses a new decentralized robust Lc design in a deregulated power system under a bilateral based policy scheme. In each control area, the effect of bilateral contracts is taken into account as a set of new input signals in a modified traditional dynamical model. The Lc problem is formulated as a multi-objective control problem via a mixed H2/H∞ control technique. In order to design a robust PI controller, the control problem is reduced to a static output feedback control synthesis, and then, it is solved using a developed iterative linear matrix inequalities algorithm to get a robust performance index close to a specified optimal one. The proposed method is applied to a 3 control area power system with possible contract scenarios and a wide range of load changes. The results of the proposed multi-objective PI controllers are compared with H2/H∞ dynamic controllers

  3. Bilateral high division of sciatic nerve

    Full Text Available Sciatic nerve is the thickest nerve in the body formed by the sacral plexus from L4 to S3 in the lesser pelvis. It emerges through the greater sciatic foramen below the piriformis and enter the gluteal region. Then the nerve passes on the back of the thigh and at the level of superior angle of popliteal fossa it terminates by dividing into tibial and common peroneal nerve. The knowledge of anatomical variations in the division of nerve is important for various surgical and anaesthetic procedures. During routine dissection in the department of anatomy, Mysore Medical College and Research Institute, Mysore, a rare bilateral high division of sciatic nerve was observed in a female cadaver aged about 40 years. In the present case there was bilateral high division of sciatic nerve. The nerve was seen dividing into two branches before it emerges through the greater sciatic foramen. The tibial nerve was entering the gluteal region below the piriformis muscle and common peroneal nerve was entering by piercing the piriformis. The knowledge of this variation is important as the nerve may get compressed with surrounding anatomical structures resulting in non discogenic sciatica. The awareness of variations is important for surgeons during various procedures like fracture, posterior dislocation of hip joint and hip joint replacement. The anatomical variations are important during deep intramuscular injections in gluteal region and also for anaesthetists during sciatic nerve block. [Int J Res Med Sci 2014; 2(4.000: 1785-1787

    Full Text Available Microspherophakia is rare bilateral congenital anamoly of the crystalline lens. The condition may be isolated , familial or it may be associated with systemic affections like Marfan's syndrome , Weil - Marchesani syndrome , hyperlysinemia and congenital rubella. Microspherophakia results in lenticular myopia , lens dislocation , usually inferiorly and inverse glaucoma. We present a case in a 8 year old child who presented with bilateral microspherophakia and anterior dislocation of lens of right eye. visual acuity in right eye was counting fingers close to face and i n left eye 6/60.IOP with perkins applanation tonometer was 30mmHg in right eye 22mmHg in left eye , cornea was hazy due to edema , anterior chamber was shallow in both eye patient was managed with emergency lens extraction of right eye and secondary ACIOL im plantation. Left eye was managed by laser peripheral iridotomy. IOP was within normal limits postoperatively in both eyes without any antiglaucoma medications. Postoperatively best corrected visual acuity in right was 6/18 and 6/9 in left eye.

  5. Unusual Bilateral Rim Fracture in Femoroacetabular Impingement

    2015-01-01

    Full Text Available This is a report of one case of bilateral acetabular rim fracture in association with femoroacetabular impingement (FAI, which was treated with a hip arthroscopic procedure, performing a partial resection, a labral reinsertion, and a subsequential internal fixation with cannulated screws. Up to date, there are in the literature only two reports of rim fracture and “os acetabuli” in association with FAI. In the case we present, the pincer and cam resection were performed without complications; the technique used was published previously. With this technique the head of the screw lays hidden by the reattached labrum. We removed partially the fractured rim fragment and the internal fixation of the remaining portion was achieved with a screw. In the event of a complete resection of the fragment, it would have ended with a LCE angle of 18° and a high probability of hip instability. We believe that this bilateral case helps establish the efficacy and reproducibility of the technique described by Larson.

    This case report describes an unexpected event that took place as a result of using improvised equipment. The patient, a 16-year-old female undergoing complex oral surgery, suffered bilateral pneumothorax following the improper use of an airway support device. During the immediate postoperative period with the patient still intubated, oxygen tubing was attached to a right angle elbow connector with the port closed and 10 L/minute oxygen flow was administered to the patient in a manner that did not allow the patient to exhale. Within seconds, pneumothorax was apparent as the patient's vital signs deteriorated, visible swelling was noted in the shoulders and neck, and there was an absence of breath sounds on auscultation. This case study has application beyond the immediate discussion of bilateral pneumothorax, serving as a caution about the unintended consequences of equipment improvisation. In addition to highlighting the hazards of providing patient care with a non-standard device, this study also provides a powerful example of the human factors that can contribute to medical errors in the healthcare setting.

Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

    Full Text Available Purpose The aim of the study was to evaluate the efficacy and safety of bilateral single-session retrograde intrarenal surgery in the treatment of bilateral renal stones. Materials and Methods From December 2008 to February 2012, 42 patients who had undergone bilateral single-session retrograde intrarenal surgery (RIRS and laser lithotripsy were included in the study. The procedures were performed in the lithotomy position on an endoscopy table under general anesthesia, beginning on the side in which the stone size was smaller. Plain abdominal radiography, intravenous urograms (IVU, renal ultrasonography (USG and / or non-contrast tomography (CT scans were conducted for all patients. The success rate was defined as patients who were stone-free or only had residual fragment less than 4 mm. Results A total of 42 patients (28 male, 14 female with a mean age 39.2 ± 14.2 were included in the present study. The mean stone size was 24.09 ± 6.37 mm with a mean operative time of 51.08 ± 15.22 minutes. The stone-free rates (SFR were 92.8% and 97.6% after the first and second procedures, respectively. The average hospital stay was 1.37 ± 0.72 days. In two patients (4.7%, minor complications (Clavien I or II were observed, whereas no major complications (Clavien III-V or blood transfusions were noted in the studied group. Conclusions Bilateral single-session RIRS and laser lithotripsy can be performed safely and effectively with a high success rate and low complication rate in patients with bilateral renal stones.

    International Nuclear Information System (INIS)

    Neuroblastoma is one of the most common malignant tumors of childhood, with 40 % arising in the adrenal glands. Bilateral adrenal involvement from synchronous development or metastatic spread of the tumor is seen in less than 10 % of children with neuroblastoma [1[. Neuroblastoma rarely presents as a cystic suprarenal mass that is difficult to differentiate from adrenal hemorrhage, extralobar sequestration, or dilated upper-pole renal calyces. To our knowledge, bilateral cystic neuroblastoma has not been previously reported. We present a case of bilateral cystic adrenal neuroblastoma to demonstrate the imaging features of this unusual entity, and to expand the differential diagnosis of bilateral cystic suprarenal masses in an infant.

    Mawromatis, Constantino

    1999-12-01

    Full Text Available Metropolitan Santiago is one of the many Latin American cities which has been developed according to a spread model of urbanisation. This pattern has caused at least two types of consequences: economic and physical ones. The former is shown in the speculation of land value at the rural fringe of the metropolitan area which has low prices, these have suddenly increased after the normative changes in the land use, from rural to urban. The later shows location of massive low-income housing and commercial malls regardless connection to the urban fabric and spatial shaping of the existing city. This results in a chaotic urban form resembling a "patchwork".This paper reviews the scope of a Chilean policy instrument called "Plan Regulador" used to control physical urban growth, particularly sprawled on the fringe of the city. It is believed that as a consequence of this Plan, normative procedures are not good enough for achieving its objectives. Conversely, urban form appears to be a result of a profitability plan made by private developers. Given the weakness of this instrument, some recommendations related to spatial models are suggested to incorporate to or complement the "Plan Regulador"./ El Plan Regulador Comunal es el instrumento normativo de planeación urbanística chilena, cuya formulación pretende regular en el ámbito comunal básicamente los siguientes aspectos: los usos de suelo, las condiciones de edificación y subdivisión del suelo, la red vial estructurante y los limites urbanos.Se cree que este instrumento es imperfecto toda vez que no incorpora en la normativa una dimensión clave del urbanismo: la morfología urbana, entendida como el sistema espacial tridimensional de la ciudad. Por el contrario, el análisis empírico demuestra que factores como la forma urbana son respuestas del libre juego de fuerzas económicas y sociales modeladoras del espacio. En consecuencia, lo que domina es un patrón de urbanización en vez de un

    Full Text Available La política ambiental en México se implementó como un mecanismo para frenar el deterioro en áreas naturales como la Reserva de la Biosfera de la Mariposa Monarca, sin embargo, se cuestiona su eficacia debido al continuo deterioro, la pérdida de bosques, la mortandad de la mariposa, y la disminución de mantos freáticos; todo esto acentuado por el turismo masivo. Esto es consecuencia de las dificultades de implementación de la política ambiental y de los actores que participan en ella. El análisis se realizó bajo el enfoque de Redes de Política Pública. La principal conclusión es que existe una limitada coordinación interinstitucional y esto dificulta la comunicación y acuerdo entre actores.

El acceso a nuevos documentos ha permitido iluminar de mejor manera los motivos del viaje: luego de su renuncia a la Acción Católica, es becado por Mons. Edwin O'Hara para ir a estudiar por un año a la Escuela de Trabajo Social de la Universidad Católica de Washington. El viaje le permite, además, tomar contacto con diversas obras sociales de la Iglesia de EE. UU y de Canadá, profundizar su estudio en la doctrina social de la Iglesia y sus aplicaciones prácticas, y proyectar dos de sus obras sociales más conocidas: el Hogar de Cristo y la ASICH. Finalmente, el contacto con uno de los países más desarrollados del mundo, le inspira en su ministerio sacerdotal a predicar que «la materia no basta» y la centralidad de «la visión de fe».This article shows the impact and the consequences of St. Alberto Hurta-do's trip to the United States in 1945. Access to new documents has shed further light on the reasons for the trip: after he renounced the Catholic Action, Mons. Edwin OHara gives him a scholarship to study at the Catholic University School of Social Work in Washington. The trip also allows him to get involved in several social works of the U.S. and Canadian Church, deepen his study of the Church's social doctrine and its practical applications, and plan two of his best-known social works: Hogar de Cristo and ASICH. Finally, contact with one of the world's most developed countries inspires him in his priestly ministry to preach that «what is material is not enough» and the centrality of the «vision of faith».

    Pleural tuberculosis is the first or second most common form of extrapulmonary tuberculosis as well as the main cause of pleural effusion in many countries. It is rare in young infants and is more common in children over 10 years of age. We report the case of a 19-month-old girl admitted for prolonged fever with unilateral pleural effusion. The mother reported a history of lymph node tuberculosis 6 years previously. Intravenous antibiotics with cefotaxime and vancomycin were started. Thoracocentesis yielded a serosanguinous exudate fluid with a lymphocyte predominance. The tuberculin skin test and PCR GeneXpert(©) on pleural fluid were negative. The initial outcome was favorable, but the chest X-rays 10 days after discharge showed bilateral pleural effusion. Pleural biopsy was proposed but the culture of pleural fluid was positive for Mycobacterium tuberculosis. The child was put under standard treatment for tuberculosis. The outcome was favorable.

  12. Rare case of bilateral carotic chemodectoma

    International Nuclear Information System (INIS)

    Glomus tumor (chemodectomy, paraganglion) is a rarely occurring tumor built of paraganglia, most often located in the common carotid artery division. This slowly increasing tumor develops mostly between the ages of 45 and 50, and more or less evenly in male and female patients. This article describes the characteristics of tumors such as chemodectomy, diagnostic methods, and procedures for medical treatment. The article describes a case of tumor in the common carotid artery bifurcation diagnosed as chemodectomy with a very rare bilateral locus. The tumor was accidentally discovered during ultrasonography, and confirmed in computer tomography examination. The first examination should be ultrasonography, complemented with color Doppler. A standard angiographic examination should be performed in the case of planned surgery, with one-time-only embolization of tumor vascularization. Computer tomography examination in the angio-CT option with RT3D reconstruction is an adequate method of imaging a tumour such as chemodectomy. (author)

    Full Text Available Perinephric lymphangioma is rare disorder that may be confused with various forms of renal cystic diseases and urinomas. In this disorder a developmental malformation results in failure of developing lymphatic tissue to establish normal communication with the rest of lymphatic system. Once there is restricted drainage of lymphatic fluid the lymphatic channels dilate to form cystic masses that may be unilocular or multilocular and may be seen unilaterally or bilaterally .This condition presents with various signs and symptoms or can be just an incidental finding which in presence of misleading clinical history may be confused with other diseases. CT scan with delayed cuts and USG guided aspiration with biochemical analysis of fluid will help us in arriving to final diagnosis.

    A 20 year old man was admitted in the surgical unit of Dhaka Medical College Hospital on August 2007 presented with Hypospadias & underdeveloped penis from childhood, gradual enlargement of both breasts for the last 10 years, absence of axillary and pubic hair from puberty & painful swelling of both testes for the last 3 years. The patient was regarded as a female upto the age of 10 years. He has got no voice change since puberty. On examination he had average body built, there was bilateral gynaecomastia, hypospadias, rudimentary penis & absence of pubic and axillary hair. His testosterone level, serum prolactin level, serum progesterone level, serum estradiol level was done. Cytology on buccal smear done and ultrasonography revealed no ovary and uterus. Ultimately patient was diagnosed as a case of androgen insensitivity syndrome (AIS). The case is reported for clinical awareness & to share our experience. PMID:19182761

  15. Bilateral Trade Flows and Income Distribution Similarity

    Science.gov (United States)

    2016-01-01

    Current models of bilateral trade neglect the effects of income distribution. This paper addresses the issue by accounting for non-homothetic consumer preferences and hence investigating the role of income distribution in the context of the gravity model of trade. A theoretically justified gravity model is estimated for disaggregated trade data (Dollar volume is used as dependent variable) using a sample of 104 exporters and 108 importers for 1980–2003 to achieve two main goals. We define and calculate new measures of income distribution similarity and empirically confirm that greater similarity of income distribution between countries implies more trade. Using distribution-based measures as a proxy for demand similarities in gravity models, we find consistent and robust support for the hypothesis that countries with more similar income-distributions trade more with each other. The hypothesis is also confirmed at disaggregated level for differentiated product categories. PMID:27137462

    2016-09-01

    This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was performed in 2 separate sessions with a significant improvement of shoulder function afterwards. No postoperative complications, pain, or recurrence of HOs were noted at 1-year follow-up. Mechanical ventilation, immobilization, neuromuscular blockage, and prolonged sedation are known risk factors for the development of HOs in the shoulder joints. Relatively early surgical resection of the HOs can be performed safely in contrary to earlier belief. Afterwards, nonsteroidal anti-inflammatory drugs and/or radiation therapy can be possible treatment modalities to prevent recurrence of HOs. PMID:27583120

    Full Text Available Marfan syndrome is an autosomal dominant systemic disorder of the connective tissue. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessels. Eye involvement may be in the form of retinal detachment which is a potentially dangerous manifestation for its sight threatening nature .We report a case where a 17 year old male developed sudden blindness due to spontaneous bilateral retinal detachment. Examination revealed features of Marfan syndrome and was stamped as a case of Marfan syndrome by Ghent criteria . The point to stress upon is that a young male developing spontaneous retinal detachment, a diagnosis of underlying Marfan syndrome should be kept in mind if appropriate clinical stigmata are present.

  2. Intensity modulated radiotherapy (IMRT) in bilateral retinoblastoma

    International Nuclear Information System (INIS)

    External beam radiotherapy (EBRT) for retinoblastoma has traditionally been done with conventional radiotherapy techniques which resulted high doses to the surrounding normal tissues. A 20 month-old girl with group D bilateral retinoblastoma underwent intensity modulated radiotherapy (IMRT) to both eyes after failing chemoreduction and focal therapies including cryotherapy and transpupillary thermotherapy. In this report, we discuss the use of IMRT as a method for reducing doses to adjacent normal tissues while delivering therapeutic doses to the tumour tissues compared with 3-dimensional conformal radiotherapy (3DCRT). At one year follow-up, the patient remained free of any obvious radiation complications. Image guided IMRT provides better dose distribution than 3DCRT in retinoblastoma eyes, delivering the therapeutic dose to the tumours and minimizing adjacent tissue damage

  3. Bilateral type emphysematous pyelonephritis: imaging evaluation

    International Nuclear Information System (INIS)

    Emphysematous pyelonephritis (EPN) is a serious infectious disease that occurs more frequently in diabetic patients. Radiological studies are indispensable for distinguishing between the two types since each is associated with a markedly different prognosis. We present a case of bilateral EPN diagnosed as type I on the basis of computed tomography findings, differentiating it from type II EPN, taking into account the prognostic value of this distinction. Type I EPN is characterized by the destruction of the renal parenchyma, a mottled or linear gas pattern and the absence of renal and perirenal fluid collection. Type II EPN is characterized by a loculated or bubbly gas pattern, the existence of fluid collection and less marked renal destruction. Type I is more aggressive and is associated with high rate of mortality. (Author) 7 refs

    Mandible is the most frequently affected bone during head and neck irradiation. Late changes in the mandible may manifest in the form of reduced bone density, dental caries, loss of spongiosa trabeculations, delayed healing following dental extraction, pathologic fractures, osteoradionecrosis, trismus, growth defects in children or second malignancies. Pathologic fractures of mandibular bone are rare and may be spontaneous or traumatic (following dental extraction). We report the case of a 55-year lady, who had undergone surgery and adjuvant radiotherapy for carcinoma oral tongue T2N0M0 on a cobalt-60 unit and was disease-free. After a follow-up of 8 years post-irradiation, she presented with sudden onset oral pain and inability to open mouth. Pantomogram showed fracture at the junction of body and ramus of the mandible bilaterally. PMID:26097342

    Full Text Available Vernal Keratoconjunctivits (VKC is a bilateral recurrent allergic interstitial conjunctival inflammation with a periodic seasonal incidence and of self limiting nature, mainly affecting the younger population. Patients of VKC on steroid therapy are at higher risk of developing steroid induced glaucoma. Raised intraocular pressure due to steroids typically occurs within few weeks of starting steroid therapy and comes back to normal on immediate stoppage of steroids. A case of steroid induced glaucoma in a 30 years old female with vernal keratoconjunctivitis. She was on topical steroids for 3-4 years. She was incompliant with the instructions to stop steroids. She eventually developed steroid induced glaucoma and glaucomatous optic neuropathy with tunnel vision.

    2009-01-01

    A 40-year-old male paddy field worker was referred for exertional shortness of breath and non-productive cough for 4 years. He had been treated for pulmonary tuberculosis twice. Chest radiograph showed extensive bilateral nodular opacities ("sandstorm-like") in the middle and lower lobe. Pulmonary function tests revealed a restrictive ventilatory defect. High resolution CT showed widespread nodular infiltration with "crazy paving" appearance and interrupted black pleura sign. This was confirmed as pulmonary alveolar microlithiasis (PAM) by trans-bronchial lung biopsy, which showed normal respiratory lining epithelium with dilated alveolar spaces containing many calcific bodies, some of which showed concentric calcification. The possibilities of silicosis (due to exposure to husk) and tuberculosis, both of which can mimic PAM clinically and radiologically, made this case a diagnostic challenge. PMID:21686505

  7. Bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis

    Full Text Available X-linked juvenile retinoschisis is a rare hereditary retinal disease characterized by a tangential splitting of the neurosensory retina which may cause early-onset visual impairment. Existence of the retinal neurosensory layer splitting on cross-sectional images of optical coherance tomography (OCT and the absence of leakage on fluorescein angiography (FA help confirming the diagnosis. Such diagnostic tests are also helpful in determining the management of the disease. However, most of the retinoschisis cavities remain stable and rarely extend to the posterior pole, many authors suggest laser prophylaxis to avoid the potential risk of retinal detachment due to holes in the outer retinal layer. Herein, we report a case with bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis who was evaluated with detailed ophthalmologic examination. Visual acuity, fundoscopy, OCT, and FA remained stable in the second year of follow-up after prophylactic argon laser treatment.

  8. La sequía de 1937 en Santiago del Estero: Antecedentes y consecuencias de un acontecimiento ambiental The drought of 1937 in Santiago del Estero: Antecedents and consequences of an environmental event

    Full Text Available Durante los años 1935 a 1937 se produjo una importante sequía que afectó duramente a las regiones áridas y semiáridas del noroeste argentino, así como de México y Estados Unidos. En esta nota se estudia la repercusión de ese acontecimiento ambiental sobre la economía y la sociedad de Santiago del Estero, que marca un antes y un después en su historia agraria. Hasta ese año se consolidó el modelo agroforestal surgido entre 1880-1900, que combinaba el obraje, la finca y la economía campesina. La gran sequía hizo fracasar dos cosechas seguidas, y disminuyó el stock ganadero vacuno y caprino en un 80%. Esto tuvo consecuencias catastróficas en una sociedad rural, cuya dieta dependía en gran medida de su propia producción, desatando la hambruna más notable en la historia contemporánea de esta provincia. Entre las numerosas consecuencias de esta sequía, estudiamos sus efectos en la población, la economía y las políticas públicas. Las iniciativas del Estado fueron dispersas y tardías, y no pudieron contener los problemas de miles de familias que enfrentaron el hambre y el desamparo social. Este drama regional adquirió dimensión nacional a través de la prensa oral y escrita, que en los últimos meses de 1937 promovió una campaña solidaria en gran escala. El éxodo inauguró un sendero migratorio hacia las zonas fabriles de Berisso, Ensenada y el Gran Buenos Aires. La sequía también estimuló la construcción de los diques Los Quiroga (1949 y la presa de embalse de Río Hondo (1968. La literatura también recogió este tema como símbolo del drama campesino en el imaginario colectivo.During the years 1935 to 1937 there was a significant drought that hit the arid and semiarid regions of northwestern argentina, as well as from Mexico and the United States. This note discusses the impact of this environmental event on the economy and society of Santiago del Estero, which marks a before and an after in its agricultural history

    Full Text Available Relata-se o caso de um paciente com dispnéia intensa ao se deitar, em que foram excluídas doenças pulmonares, neuromusculares ou cardíacas, cuja investigação revelou paresia diafragmática bilateral. Um sinal chave para o diagnóstico foi a evidência de respiração paradoxal com o doente em decúbito supino. Havia piora da oxigenação e da capacidade vital forçada com a mudança da posição ortostática para supina. A fluoroscopia ortostática foi normal. A pressão inspiratória máxima estava muito reduzida. A estimulação elétrica transcutânea do diafragma foi normal, e a eletroestimulação do nervo frênico mostrou ausência de resposta, permitindo o diagnóstico de paresia bilateral do diafragma.We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy was normal. Maximal inspiratory pressure was severely reduced. The responses to transcutaneous electric stimulation of the diaphragm were normal. However, electric stimulation of the phrenic nerve produced no response, leading to the diagnosis of bilateral diaphragmatic paresis.

    Conclusions: Use of bilateral IGAP flaps for breast reconstruction helps to avoid asymmetry of the inferior buttock volume and shape. Bilateral flaps provide sufficient tissue volume and allow for reconstruction of a breast comparable to the unaffected side. In patients with moderate-to-high projection breast whose abdominal tissue cannot be used for reconstruction, IGAP flaps may be a suitable alternative.

    The aim of this article is to report the MRI features of bilateral parotid haemangiomas of infancy and highlight the diagnostic and prognostic value of MRI especially with regard to those lesions that may cause respiratory compromise. Retrospective review of MRI scans in six infants with bilateral parotid haemangiomas. The bilateral haemangiomas were symmetrical in all but one patient. On T1-weighted images the masses were isointense to muscle and on T2 they were hyperintense with numerous small vessels giving a septated appearance. There was vivid enhancement with gadolinium in all cases. In three patients, deep bilateral extensions were demonstrated involving the parapharyngeal spaces resulting in respiratory compromise which required tracheostomy. Bilateral parotid haemangiomas are rare, but when present may have deep extensions, which can result in respiratory compromise requiring tracheostomy. (orig.)

  11. El lactato como posible factor del mecanismo de fatiga muscular.

    Directory of Open Access Journals (Sweden)

    José Carlos Giraldo T.

    2009-10-01

    Full Text Available Se revisa el papel del lactato en la función muscular. Se destacan los siguientes conceptos: el lactato es un intermediario metabólico que aumenta durante el ejercicio de alta intensidad, como consecuencia de la elevada actividad glicolítica. En esas condiciones la formación de ATP se asocia con generación de iones lactato e H+ y se reduce el pH de la célula activa. Si hay fatiga, el aumento en los niveles de lactato se correlaciona con la magnitud en la caída de la fuerza y los niveles de lactato alcanzados a un determinado nivel de actividad dependen del tipo de la fibra muscular. La salida de lactato de la fibra ocurre principalmente por 3 mecanismos de los cuales el más importante es el cotransporte acoplado de lactato-H+, cuya actividad depende del tipo de fibra y del patrón de activación así como del pH y de la concentración del amortiguador (buffer externos. De los varios factores responsables de la fatiga muscular, la disminución de pH se ha señalado como uno de los más importantes. No obstante, a pesar de la relación entre fatiga muscular y disminución de pHi, ésta no parece ser suficiente para explicar el grado de reducción de la fuerza durante la fatiga. Recientemente se han realizado experimentos que muestran un efecto inhibidor del lactato sobre el canal de liberación de calcio del retículo sarcoplásmico, lo que sugiere fuertemente que el lactato per se, y no necesariamente el cambio de pHi asociado, puede jugar un papel importante en el mecanismo de la fatiga. Por otra parte, el lactato podría tener efecto benéfico en la recuperación de la fuerza tetánica y de la capacidad de mantener la fase de meseta durante el tétanos, que se reducen por efecto de la fatiga. Asimismo, el aumento de lactato podría jugar un papel protector de la fibra durante la fatiga, mediante la activación de los canales de K+ sensibles a ATP. El músculo produce y consume lactato y al aumentar sus niveles en la sangre, este ion lo

  12. Comparative gait initiation kinematics between simulated unilateral and bilateral ankle hypomobility: Does bilateral constraint improve speed performance?

    Improvement of motor performance in unilateral upper limb motor disability has been shown when utilizing inter-limb coupling strategies during physical rehabilitation. This suggests that 'default' bilateral central motor commands are facilitated. Here, we tested whether this bilateral motor control principle may be generalized to the lower limbs during gait initiation, which involves alternate bilateral actions. Disability was simulated by strapping to produce ankle hypomobility. Healthy adult subjects initiated gait at a self-paced speed with no ankle constraint (control), or with the stance, swing or bilateral ankles strapped. The duration of the anticipatory postural adjustments lengthened and the center of mass instantaneous progression velocity at foot-off decreased when the ankle was strapped. During the step execution phase, progression velocity at foot-contact was higher when both ankles were strapped compared to unilateral strapping of the stance ankle. These findings suggest that bilateral central motor commands are favored during walking tasks. Indeed, unilateral constraint of the stance ankle should compel the central nervous system to adapt specific commands to the constraint and normal sides whereas the 'default' bilateral motor commands would be utilized when both ankles are strapped leading to better kinematics performance. Bilateral in-phase upper limb coordination and bilateral alternating lower limb locomotor movements may share similar control mechanisms. PMID:26197055

  4. Controversias de la ooforectomía profiláctica bilateral durante la histerectomía electiva Profilactic bilateral ooforectomy during elective hysterectomy

    Directory of Open Access Journals (Sweden)

    Orozco-Saborío Leonardo

    2008-09-01

    Full Text Available El término ooforectomía profiláctica implica que los ovarios son normales al ser removidos quirúrgicamente y que se realiza por posibles beneficios futuros, tales como la prevención de cáncer de ovario o evitar reintervenciones quirúrgicas ginecológicas por patología en el anexo remanente. Sin embargo, se ha sugerido que la producción de andrógenos en los ovarios perimenopáusicos tiene un papel prominente en la calidad de vida y el bienestar sexual de la mujer. Al igual que se ha relacionado la ooforectomía bilateral con un aumento en la enfermedad cardiovascular y la mortalidad en mujeres que no usaron terapia de reemplazo hormonal. Hasta que exista evidencia inequívoca proveniente de estudios controlados, aleatorizados y adecuadamente diseñados, la ooforectomía profiláctica bilateral coincidente con una histerectomía electiva en pacientes de bajo riesgo para cáncer de ovario, debe ser considerada con gran cautela. La evidencia actual sugiere que la decisión de realizarla o no durante una histerectomía electiva, se basa más en opinión que en estudios aleatorizados bien diseñados y de peso metodológico, pudiéndose no justificar la realización de tan elevado número de ooforectomías profilácticas en la práctica clínica actual.The term prophylactic oophorectomy implies that the ovaries are normal at the time of their surgical removal and that it is performed for possible future benefits, such as prevention of ovarian cancer or to avoid eventual gynecological surgical interventions. However, it has been suggested that the production of androgens in the ovaries in perimenopausal women has an important rol in the quality of life and sexual well being. Bilateral oophorectomy has also been related with an increased risk of cardiovascular disease and mortality in women that did not use hormonal replacement therapy. Until more research of better methodological quality becomes available, prophylactic oophorectomy at the time

  9. Cortisol salival como indicador de estrés fisiológico en niños y adultos: revisión sistemática

    Directory of Open Access Journals (Sweden)

    M. J. Aguilar Cordero

    2014-05-01

    Full Text Available El cortisol salival es una hormona esteoridea producida en el eje hipotálamo-pitutitario-adrenal que se segrega en la saliva, sobre todo cuando las personas se estresan. Un nivel elevado de cortisol en saliva puede ser producido por muchos factores diferentes, entre los que se encuentran algunas alteraciones, como la obesidad y otras afecciones psicológicas. Los artículos seleccionados para ser incluidos en esta revisión se tomaron de Google Scholar y Medline, y con un total de 57 artículos. La validez de los mismos viene dada por el grado de evidencias demostrado, por las recomendaciones allí recogidas y por la aplicabilidad a nuestro contexto. En esta revisión se han considerado los estudios que investigan el cortisol salival y el estrés en niños y adultos. También se han tenido en cuenta los que relacionan unos niveles altos de cortisol salival con otras alteraciones, como ansiedad, TDAH, fobia social o la carencia afectiva. Los estudios demuestran que el cortisol salival es un claro indicador de estrés, tanto en niños como en adultos. Las principales consecuencias de un alto nivel de esta hormona en la saliva son las siguientes: reducción de la función inmunológica, que afecta a la cicatrización y, como consecuencia, a un mayor tiempo de recuperación. También se relaciona con un déficit en el crecimiento físico de los niños, así como con un aumento de la presión arterial y de la frecuencia cardíaca, tanto en niños como en adultos.

    2013-01-01

    Full Text Available We herein report a case of synchronous bilateral solid papillary carcinoma of the breast. A 73-year-old female had a mass that was detected in the right breast on mammography. An ultrasound examination revealed one intracystic tumor in the right breast and two tumors in the left breast. A fine-needle aspiration biopsy of these three tumors was performed, which revealed a diagnosis of malignancy. A magnetic resonance imaging examination of the breasts showed diffuse small nodules surrounding these tumors bilaterally. Bilateral partial mastectomy and a sentinel lymph node biopsy were performed. Lymph node metastasis was detected in the right axilla, and additional lymph node dissection was performed. The pathological diagnosis was synchronous bilateral breast cancer, invasive ductal carcinoma NOS of the right breast, mucinous carcinomas of the left breast, and bilateral SPCs. A wide range of surgical margins were positive for SPCs, and additional bilateral total mastectomy was then performed. To the best of our knowledge, little is known about synchronous bilateral SPCs. Our case indicates that some SPCs can be widely scattered and make up a variety of invasive carcinomas. It is difficult to make a correct preoperative evaluation in such cases.

  19. Rehabilitation for bilateral amputation of fingers

    Stapanian, Martin A.; Stapanian, Adrienne M.P.; Staley, Keith E.

    2010-01-01

    We describe reconstructive surgeries, therapy, prostheses, and adaptations for a patient who experienced bilateral amputation of all five fingers of both hands through the proximal phalanges in January 1992. The patient made considerable progress in the use of his hands in the 10 mo after amputation, including nearly a 120% increase in the active range of flexion of metacarpophalangeal joints. In late 1992 and early 1993, the patient had "on-top plasty" surgeries, in which the index finger remnants were transferred onto the thumb stumps, performed on both hands. The increased web space and functional pinch resulting from these procedures made many tasks much easier. The patient and occupational therapists set challenging goals at all times. Moreover, the patient was actively involved in the design and fabrication of all prostheses and adaptations or he developed them himself. Although he was discharged from occupational therapy in 1997, the patient continues to actively find new solutions for prehension and grip strength 18 yr after amputation.

    2015-11-01

    Full Text Available : Mineralisation of all components of stylohyoid complex or chain, a 2nd branchial arch derivative is frequently reported. But bilateral occurrence of continuous bands of ossified tissue involving stylohyoid complex, are less commonly encountered. An adult skull specimen presented abnormally long osseous bands extending from base of skull in place of styloid process. On left side a band of 6.5cm long x1cm wide and 0.3cm in thickness, and on right side an irregularly rounded elongated structure of 7.5cm length were noticed. Lower end of the left process was fused to hyoid bone. Either abnormally long styloid process or this type of ossified stylohyoid complex may be a causative factor for severe pharyngeal pain, dysphagia, may be a cause for occasional swelling in submandibular region or may be associated with Eagle syndrome. Due to its close proximity to tonsillar bed, if elongated it may be felt during tonsillectomy in tonsillar fossa. In this backdrop reports of this type may be of interest to clinicians.

    Full Text Available The aim of this work is the integration of a virtual environment containing a deformable object, manipulated by an open kinematical chain virtual slave robot, to a bilateral teleoperation scheme based on a real haptic device. The virtual environment of this hybrid bilateral teleoperation system combines collision detection algorithms, dynamical, kinematical and geometrical models with a position–position and/or force–position bilateral control algorithm, to produce on the operator side the reflected forces corresponding to the virtual mechanical interactions, through a haptic device. Contact teleoperation task over the virtual environment with a flexible object is implemented and analysed.

    We report the case of a 22-year-old woman with pycnodysostosis associated with bilateral congenital pseudarthrosis of the clavicle. The patient was first seen at the age of 19 years and had no symptoms during the 3-year follow-up period. The diagnosis of pycnodysostosis was made by typical clinical and radiological findings. Bilateral painless mid-clavicular mass and plain radiograms confirmed the diagnosis of bilateral congenital pseudarthrosis of the clavicle. Surgery was not performed for pseudarthrosis of the clavicles, just observation was preferred. PMID:12721693

    Full Text Available Tibial tubercle sleeve fracture is a rare injury. In concept, it is similar to the patellar sleeve fracture in a skeletally immature patient. We describe a unique case of simultaneous bilateral tibial tubercle sleeve fractures in a 12-year-old boy. Radiographs and MRI confirmed the injury. The patient underwent open surgical repair of bilateral sleeve fractures with suture anchor fixation. At the final followup, 3 years after his initial injury, the patient demonstrated full knee function bilaterally without radiographic evidence of growth disturbances.

    Full Text Available In this case report, we present occurrence of bilateral angle closure glaucoma in a 9-year-old girl with geleophysic dysplasia. Bilateral YAG laser iridotomy was applied, but intraocular pressure (IOP remained at high levels, necessitating bilateral trabeculectomy with mitomycin C. On her follow-up examinations for 3 years, IOP remained in the mid-20s with no need for further intervention or antiglaucoma medication. There are few reports describing the ocular findings of geleophysic dysplasia in literature. To our knowledge, this is the first case report describing an application of glaucoma surgery and its results at geleophysic dysplasia.

    Abstract We report a 64-year-old man with diabetic chorea whom we investigated with dopamine transporter SPECT, 18F FDG PET, 99mTc ethylcysteinate dimer (ECD) SPECT, and 123I metaiodobenzylguanidine (MIBG) scintigraphy. Dopamine transporter SPECT revealed reduced 123I ioflupane binding in the bilateral striatum. 18F FDG PET showed metabolic dysfunction in the bilateral striatum, as shown in earlier studies. 99mTc ECD SPECT revealed reduced brain perfusion in the bilateral caudate nucleus and putamen. 123I MIBG scintigraphy revealed no cardiac sympathetic nerve dysfunction. Our case suggests a possible nigrostriatal presynaptic dopaminergic involvement in diabetic chorea. PMID:26975011

    Full Text Available Maisonneuve fractures result from a disruption of the medial ankle structures and a proximal fibular fracture. Patient complaints can be misleading and there is a significant rate of delayed diagnosed injuries. We present a case of bilateral Maisonneuve fractures after a fall due to a syncopal collapse. A precise clinical examination led to this rare diagnosis. The injuries were treated with syndesmotic screw fixation, removal of hardware followed after 6 weeks. The patient was asymptomatic at threemonths follow up. Patients with bilateral injuries undergoing standard surgical treatment can gain full recovery, but high suspicion in clinical examination is needed to detect this uncommon bilateral injury.

    Full Text Available Sphenoid sinus mucocele comprises only 2% of all paranasal sinus mucoceles. In literature, there is a case report on sphenoidal mucocele causing bilateral optic neuropathy, with unilateral partial recovery and cranial nerve palsy, but we did not come across any literature with bilateral optic neuropathy and ophthalmoplegia together caused by spheno-ethmoidal mucocele. We present such a rare case of spheno-ethmoidal mucocele causing bilateral optic neuropathy and unilateral sixth nerve palsy who had postsurgery, unilateral good vision recovery, and complete resolution of sixth nerve palsy.

    Full Text Available Muscle variation may occur due to genetic or developmental causes. Some variations may compromise the vascular, muscular or nervous system in the region. Bilateral muscle variation in popliteal fossa is very rare. In present study an instance of bilateral muscle variation in popliteal fossa, arising from different muscles like gastrocnemius and from biceps femoris is recorded. There is no report of such variations. These observations are rare of its kind because of bilateral asymmetrical presence and difference in the origins in different legs. This is the first report as for the literatures available. Clinical and functional importance of such variation is discussed with the morphological aspects of this anomalous muscle.

  11. Point Climat no. 11 'Japan's Bilateral Offset Crediting Mechanism: A Bilateral Solution to a Global Issue?'

    International Nuclear Information System (INIS)

    Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: In order to achieve its long-term emission reduction target following the Fukushima incident, Japan would rely more heavily on international offsetting activities. Concurrent to vigorous proposals to reform the CDM, Japan is also promoting an offset crediting scheme through bilateral agreements with developing countries as a post-2012 market mechanism. Despite potential benefits, issues relating to the accounting rules, environmental integrity and implications to carbon markets warrant further consideration prior to international recognition

    Full Text Available El cuidado provisto por familiares o amigos a los adultos dependientes es un proceso social decisivo para el bienestar de la sociedad española. Este tipo de apoyo tiene intensas consecuencias sobre quienes cuidan. En este artículo se plantea que la valoración precisa del impacto de la dependencia en el entorno social requiere de análisis comprensivos y multidisciplinares, y se elabora una propuesta de clasificación de las consecuencias del cuidado familiar sobre el cuidador. En dicha propuesta estos efectos pueden ser positivos o negativos, y afectar a diferentes dimensiones vitales de los cuidadores: salud, economía o relaciones sociales.Care provided by relatives or friends to dependent people is a key process to promote wellbeing in Spanish society. This type of support has intense consequences over caregivers' lives. Comprehensive and multidisciplinary analyses are required to assess dependency effects over social network. In this paper we elaborate a classification of types of family care consequences over caregivers. We differentiate between positive or negative consequences, and between consequences affecting caregivers' health, economy and/or social relations.

  15. CT-guided once-through bilateral percutaneous needle puncturing sclerotic therapy for bilateral multiple renal cysts: preliminary results

    International Nuclear Information System (INIS)

    Objective: To evaluate CT-guided once-through bilateral percutaneous needle puncturing, aspiration and injection of sclerotic agents (ethanol) in treating bilateral multiple renal cysts. Methods: CT-guided once-through bilateral percutaneous needle puncturing sclerotic therapy was performed in 19 patients with bilateral multiple renal cysts. First, under CT guidance the puncture points and puncture routs were decided, then, puncturing, aspiration, rinsing and ethanol injection of the cysts were taken place by turn. The clinical results were analyzed. Results: bilateral percutaneous needle puncturing sclerotic therapy was successfully completed in all 19 cases. The whole procedure was well tolerated by all patients. The mean operative time was 23 minutes with a range of 20-35 minutes. No severe complications occurred. Conclusion: With proficient manipulation, CT-guided bilateral percutaneous needle puncturing sclerotic therapy for bilateral multiple renal cysts can be smoothly carried out. The technique can reduced the number of sclerotherapy times, cut down the medical expenses and, therefore, get twofold results with half the effort. (authors)

    2011-04-01

    Full Text Available Objetivo: Determinar la prevalencia, la naturaleza y las consecuencias de los abusos sexuales sufridos durante la infancia o la adolescencia. Métodos: 2.159 estudiantes de la Universidad de Granada respondieron voluntariamente y de forma anónima a un cuestionario sobre abuso sexual. Establecido el grupo de víctimas, se formó otro de comparación con estudiantes sin antecedentes de abusos. En una segunda sesión se evaluó la salud mental de ambos grupos. Resultados: 269 (12,5% estudiantes manifestaron haber sufrido abusos sexuales antes de los 18 años de edad. El 62,8% de los abusos consistió en tocamientos y la edad media de inicio fue a los 8,8 años. Los perpetradores, mayoritariamente varones y un 44% menores de edad, solían cometer los abusos en el hogar de la víctima o en el suyo, aprovechándose de las visitas o de su estrecha vinculación. Alrededor del 50% se sirvió del engaño o del juego. En cuanto a la salud mental de las víctimas, las universitarias con antecedentes de abusos sexuales tenían menor autoestima y asertividad, y puntuaciones más altas en actitud vital negativa, depresión y ansiedad, que las del grupo de comparación. Las víctimas varones, sin embargo, sólo diferían de los universitarios sin antecedentes de abusos en su mayor nivel de ansiedad. Conclusiones: Los resultados demuestran la gravedad del problema de los abusos sexuales a menores y sus consecuencias, así como las circunstancias en que se producen y el perfil de los agresores y de las víctimas; unos resultados relevantes para la planificación de programas de detección y prevención de los abusos.Objective: To analyze the prevalence, nature and consequences of sexual abuse during childhood or adolescence. Methods: A total of 2,159 college students from the University of Granada anonymously completed a questionnaire on sexual abuse. A group of sexual abuse survivors was established and a comparison group without a history of abuse was selected

  17. El singular como diferencia divina

    Directory of Open Access Journals (Sweden)

    Maria Jose Binetti

    2012-01-01

    Full Text Available Mucho se ha hablado sobre la posición de la diferencia como motor dialéctico de la existencia singular kierkegaardiana. El pecado, el otro o el Otro fisuran la subjetividad humana y la obligan a una identidad que guardará siempre la herida. El sujeto de la escisión es, en este sentido, el existente mismo, y tal debe ser el caso si la perspectiva se concentra en la individualidad. No obstante, y desde el punto de vista especulativo, creemos que los mismos principios utilizados por Kierkegaard para explicar el dinamismo de la existencia singular nos llevan más lejos, a saber, nos conducen al absoluto mismo como sujeto último de toda alteridad, respecto del cual el singular hace la diferencia.

    After China and Australia established diplomatic ties in 1972, bilateral relations developed rapidly. People-to-people links, politicalexchanges and trade and economic cooperation played an increasingly larger part in the foreign policies of the two countries. In the post global financial crisis era, bilateral relations have remained positive and played an imPortant role in ensuring the stability and prosperity of the Pacific region. There have been several unavoidable misunderstandings and even disagreements between the two countries, which has influenced mutual trust and policies. This article will aim to analyze the history and current situation of the Sino-Australian relationship in an objective and comprehensive way; to look ahead to future bilateral relations, and make policy recommendations for the further development of bilateral ties to increase mutual understanding and promote a more positive future for Sino-Australian relations.

  19. Delayed-onset bilateral abducens paresis after head trauma

    2012-01-01

    Full Text Available Bilateral sixth nerve paresis following closed head injury, though rare, is a known entity. However, delayed-onset post-traumatic bilateral abducens paresis is extremely rare. We present two cases. The first patient had onset of bilateral abducens paresis 2 weeks after closed head injury and the second patient after 3 days. The cause in the former was detected to be chronic subdural hematoma and in the latter is speculated to be edema/ischemia due to injury to soft tissue structures housing these nerves. The delayed onset of bilateral abducens paresis following head injury may vary according to the cause. There may be another mechanism of injury apart from direct trauma. Though rare, it needs to be evaluated and may have a treatable cause like elevated intracranial pressure.

    Limbal stem cell deficiency (LSCD) is now established as a distinct entity with a spectrum of clinical manifestations. Bilateral LSCD presents a unique set of challenges to the clinician dealing with ocular surface disease, due to the underlying causes, clinical presentation, and adnexal status, as well as lack of a source of autologous limbal stem cells. Various surgical modalities have been described to achieve visual rehabilitation in patients with bilateral LSCD. These can primarily be divided into cell-based therapies and implantation of keratoprostheses. In this review, the surgical options for management of bilateral LSCD, including autologous and allogeneic cell-based therapies and different types of keratoprostheses are described and classified. The indications, prerequisites, technique, results and complications of each modality are discussed. Based on the status of the ocular surface, an algorithm for choosing appropriate surgical management for vision restoration in bilateral LSCD has been proposed. PMID:27151421
