    Carla De Negri

    Full Text Available Se presenta el caso clínico, de una niña de 2 años de edad, nacida en el Centro Hospitalario Pereira Rossell, portadora del Síndrome KID. Se trata de una displasia congénita ectodérmica caracterizada por la asociación de queratitis, ictiosis y sordera. Es producida por un desorden autosómico dominante, esporádico. Algunos autores lo refieren asociado a la presencia de alteraciones estructurales de órganos dentarios, del tipo hipoplasia e hipomineralización del esmalte y también a gingivitis y candidiasis a nivel de la mucosa bucal. La intervención oportuna del odontopediatra, integrando el equipo de salud, brinda un aporte importante, en la búsqueda de estrategias terapéuticas adecuadas al paciente y al contexto asistencial. El abordaje de tratamiento en pacientes portadores del Síndrome KID debe ser multidisciplinario, requiriendo en niños, la integración de un equipo de salud con pediatra, dermatólogo, oftalmólogo, otorrinolaringólogo y odontopediatra

    2016-01-01

    Resumen Objetivo: Describir paso a paso el abordaje a la cisterna ambiens por la vía suboccipital retrosigmoidea supracerebelosa infratentorial (SRSI). Descripción: El abordaje SRSI se realiza de la misma manera que el abordaje suboccipital retrosigmoideo (SR), utilizado habitualmente para acceder a la patología del ángulo pontocerebeloso, con las siguientes modificaciones: (1) utilizamos siempre la posición semisentado, (2) la craneotomia-craniectomia debe exponer el seno transverso y extenderse 5 cm medialmente hacia el inion, (3) al realizar la apertura dural es necesario rebatir la duramadre junto con el seno transverso hacia cefálico con puntos de tracción, (4) bajo magnificación con microscopio quirúrgico se debe realizar la apertura de la cisterna cerebelobulbar para drenar líquido cefalorraquídeo, (5) en el plano supracerebeloso es fundamental cortar las bridas aracnoidales y de ser necesario debemos coagular y cortar las venas puente, todas estas maniobras sumadas al efecto de la gravedad brindan mayor apertura del corredor supracerebeloso. Conclusión: El abordaje a la cisterna ambiens por la vía SRSI es una opción segura para el acceso de patologías tumorales que se alojan en esta zona con un componente predominantemente infratentorial.

  8. Unilateral initiatives

    1988-01-01

    This paper reports on arms control which is generally thought of in terms of formal negotiations with an opponent, with the resulting agreements embodied in a treaty. This is not surprising, since arms control discussions between opponents are both important and politically visible. There are, however, strong reasons for countries to consider and frequently take unilateral initiatives. To do so is entirely consistent with the established major precepts of arms control which state that arms control is designed to reduce the risk of war, the costs of preparing for war, and the death and destruction if war should come. Unilateral initiatives on what weapons are purchased, which ones are eliminated and how forces are deployed can all relate to these objectives. There are two main categories of motives for unilateral initiatives in arms control. In one category, internal national objectives are the dominant, often sole, driving force; the initiative is undertaken for our own good

    Full Text Available En este trabajo, la autora pretende determinar la posibilidad de conocer los orígenes de seres humanos nacidos bajo técnicas de reproducción humana asistida. Para ello, procedió a analizar el régimen proyectado en el territorio nacional, conjuntamente, a un análisis de las regulaciones extranjeras. Comprendidos en su trabajo se encuentran las visiones acerca de los derechos de toda persona a formar una familia; los derechos de los niños, niñas y adolescentes; y el derecho de los terceros involucrados en estas técnicas. Asimismo, realizo una reseña sobre cuestiones históricas y sociológicas, entre otras, que hacen al contexto de estas técnicas; permitiéndole arribar a la conclusión de que el derecho a conocer los orígenes necesita de un abordaje interdisciplinario, que debe darse no sólo desde el Estado; sino especialmente dentro del marco del seno familiar, con los debidos cuidados y afecto que sólo la familia puede brindar; todo esto acompañado de una necesaria y fundamental construcción social para insertar estos cambios en la cultura del país.

  12. Molienda asistida con microondas de un coque metalúrgico

    Directory of Open Access Journals (Sweden)

    Ruisánchez, Esteban

    2014-06-01

    Full Text Available Metallurgical cokes are composed of graphitic carbon (s2p2 and different inorganic compounds with very different capacities to absorb microwave radiation. Moreover, due to the electric conductivity shown by the metallurgical cokes, microwave radiation produces electric arcs or microplasmas, which gives rise to hot spots. Therefore, when these cokes are irradiated with microwaves some parts of the particle experiment a rapid heating, while some others do not heat at all. As a result of the different expansion and stress caused by thermal the shock, small cracks and micro-fissures are produced in the particle. The weakening of the coke particles, and therefore an improvement of its grindability, is produced. This paper studies the microwave-assisted grinding of metallurgical coke and evaluates the grinding improvement and energy saving.Los coques metalúrgicos están compuestos mayoritariamente de carbono grafítico (s2p2 y diferentes compuestos inorgánicos con distintas capacidades de absorber la radiación de microondas. Cuando se irradian con microondas fragmentos de estos coques, algunas partes de las partículas experimentan un rápido calentamiento, mientras otras no. Además, debido a que el coque presenta una cierta conductividad eléctrica, al ser irradiados con microondas se producen de forma puntual arcos eléctricos o microplasmas, dando lugar a puntos muy calientes. Como consecuencia de las diferentes dilataciones y tensiones producidas por el choque térmico, se producen en las partículas pequeñas grietas y microfisuras. Esto produce una mayor fragilidad en las partículas de coque y un incremento en la molturabilidad de las mismas. En el presente artículo se estudia la molienda de coque asistida con microondas y se evalúan las mejoras en la molturabilidad y el ahorro de energía producido.

Se obtuvieron resultados que concuerdan con la literatura médica revisada, y se concluye como una superior alternativa en los pacientes con miastenia gravis, por las bondades que se observan en los aspectos de baja invasividad, mínimas complicaciones y menor estadía hospitalaria.Video-assisted thoracoscopic thymectomy in children is a real novelty in Cuba to take care of the incidence of myasthenia gravis in the young population. Although such method is not wholly complication-free, if we compare it with the classical technique to thymus approach, then the risks are minimal. The present paper provides information on 4 patients of both sexes, adolescents, ASA II and due to undergo major elective surgery (thymectomy. Parameters such as heart rate, electrocardiogram, systolic and diastolic arterial pressures, respiratory rate, esophagic temperature, pulse oxymetry and capnometry were measured before, during and after surgery. The results achieved were in line with the reviewed literature so the conclusion was reached that this technique is a better choice for patients with myasthenia gravis because of the advantages it offers such as low invasiveness, minimum

  13. Unilateral removable partial dentures.

    Science.gov (United States)

    Goodall, W A; Greer, A C; Martin, N

    2017-01-27

    Removable partial dentures (RPDs) are widely used to replace missing teeth in order to restore both function and aesthetics for the partially dentate patient. Conventional RPD design is frequently bilateral and consists of a major connector that bridges both sides of the arch. Some patients cannot and will not tolerate such an extensive appliance. For these patients, bridgework may not be a predictable option and it is not always possible to provide implant-retained restorations. This article presents unilateral RPDs as a potential treatment modality for such patients and explores indications and contraindications for their use, including factors relating to patient history, clinical presentation and patient wishes. Through case examples, design, material and fabrication considerations will be discussed. While their use is not widespread, there are a number of patients who benefit from the provision of unilateral RPDs. They are a useful treatment to have in the clinician's armamentarium, but a highly-skilled dental team and a specific patient presentation is required in order for them to be a reasonable and predictable prosthetic option.

    Resumen Objetivos: El objetivo de este estudio fue comparar, en fusiones lumbosacras cortas, el ángulo de convergencia de los tornillos pediculares entre el abordaje posterolateral tipo Wiltse y el abordaje mediano convencional. Método: Se revisaron en forma retrospectiva los controles en tomografía axial computada (TAC) de 76 tornillos pediculares lumbares y sacros colocados por vía posterior, mediante un abordaje mediano convencional (n: 38) o por vía posterolateral transmuscular tipo Wiltse (n: 38). Se incluyeron fusiones lumbosacras cortas desde L3 a S1, en pacientes adultos, con patología degenerativa. Se excluyeron los tornillos con una brecha ósea >4 mm en cualquier dirección, los casos con instrumentaciones pediculares previas y aquellos con curvas en el plano coronal mayores de 20°. Resultados: Considerando la totalidad de los implantes, el ángulo de convergencia fue de 23,3° (+/- 15,82). La angulación promedio, en el grupo AW, fue de 29,3° (+/- 9,72). En el grupo AC, el grado de convergencia de los implantes fue de 17,2° (+/- 10,58). Esta diferencia fue estadísticamente significativa (P < 0,0001). Para el grupo AW, el grado de convergencia según nivel fue el siguiente: L3: 31,2° (+/- 1,9); L4: 31,4° (+/- 2,76); L5: 31,1° (+/- 5,62); S1: 24,2° (+/- 12,16). El promedio del ángulo del tornillo según nivel para el grupo AC fue: L3: 16° (+/- 7,16); L4: 20,3° (+/- 6,9) L5: 15,9° (+/- 13,38); S1: 15,2° (+/- 14,32). Los implantes del grupo AW tuvieron ángulos significativamente más convergentes que el grupo AC en todos los segmentos explorados. Conclusión: En las fusiones lumbosacras cortas, la utilización del abordaje tipo Wiltse permitió la colocación de tornillos pediculares con más convergencia que en el abordaje mediano convencional. La relevancia clínica de este hecho es desconocida y se requerirían trabajos prospectivos randomizados para determinar la misma. PMID:29142777

    Full Text Available Salud, contemporáneamente, se entiende como un estado de completo bienestar físico, mental y social, y no solamente la ausencia de enfermedad. La actividad asistida por animales cumple este concepto y ya se utiliza hace unos años, como medida complementaria al tratamiento farmacológico, con el objetivo de la mejora y el bienestar del paciente. Su eficacia se ha demostrado a través de estudios de todo el mundo, en diferentes áreas como pediatría, geriatría y psiquiatría, entre otros, y trayendo beneficios tanto físicos como para la salud mental de las personas institucionalizadas. Ante esta realidad, hemos tratado de identificar cuáles son las investigaciones publicadas sobre el tema hasta el año 2013, en cinco bases de datos principales (Bireme, Cochrane, Embase, Pubmed y Scielo de la palabra “animal-assisted activity”. Se excluyeron los elementos repetidos en la misma base de datos, así como uno en japonés , uno en alemán, y que se centró en la terapia asistida con animales y no en la actividad asistida por animales. 55 artículos fueron encontrados en las cinco bases de datos: Bireme (2 8, Embase (13 Cochrane (1 Pubmed (11 y Scielo (2. Sólo 17 artículos cumplieron los criterios de inclusión preestablecidos. Todos mostraron resultados positivos en la aplicación de la actividad asistida por animales para los enfermos o personas en el aislamiento social. De este modo, se puede observar que esta práctica, aunque importante para ayudar a la búsqueda de lo bienestar integral del paciente y que está siendo acepta y formalizado en muchos países, sigue estando muy poco extendida científicamente.

    Full Text Available Los abordajes endoscópicos a la base de cráneo anterior se han desarrollado de forma muy importante en las últimas décadas y continúan extendiéndose paralelamente a la aparición de nuevo instrumental y equipo que facilitan su aplicación. Factores importantes que han contribuido a ello son la posibilidad de acceder de forma directa a zonas difíciles y la disminución de morbilidad que pueden aportar, manteniendo los resultados esperados. Pero también tienen desventajas y limitaciones pues requieren conocimiento anatómico y el uso de material específico en un campo quirúrgico limitado por el espacio, estructuras anatómicas vitales y la visión bidimensional. La correcta planificación quirúrgica y la selección de los pacientes son elementos fundamentales. Esto nos permitirá determinar si es posible este tipo de abordaje, conocer la localización de la lesión, la zona de entrada al cráneo y el corredor que deberemos utilizar para ello. Los abordajes endoscópicos, correctamente indicados y planificados son procedimientos seguros y efectivos.

    S. Mordon

    Full Text Available La fase final de toda cirugía es la sutura y su cicatriz correspondiente y, frecuentemente, ésta es la única secuela visible de una intervención. La técnica LASH (cicatrización cutánea asistida por láser, estimula los mecanismos de reparación de la piel por efecto térmico, condicionando la calidad de la cicatrización. Estudios experimentales en ratones comparando los resultados obtenidos en heridas quirúrgicas radiadas con laser diodo 810 nm tras ser suturadas, con los obtenidos en igual tipo de heridas suturadas de manera convencional, han demostrado que se consiguen cicatrices mucho menos visibles cuando se practica el tratamiento con láser. La histología confirma, comparativamente, una notable aceleración del proceso cicatricial con modificación del TGFβ (Transforming Growth Factor-Beta directamente implicado en la reparación tisular, en los animales en los que la sutura fue asistida por láser. Igualmente, el análisis tensiométrico demostró mayor resistencia a la acción de estiramiento mecánico en estas heridas. Estudios clínicos en pacientes sometidos a dermolipectomia, reducción mamaria y estiramiento facial, demuestran que al tratar con LASH una parte o una de las líneas de sutura, los análisis realizados tanto por los pacientes como por cirujanos independientes a los 8 días, 3 meses y un año, evidencian resultados más favorables para la técnica láser, Las dosis eficaces determinadas para las fluencias láser están entre 80 y 120 J/cm². La técnica LASH es simple de efectuar, reproducible, rápida y ofrece una clara evidencia de que es posible reducir considerablemente la cicatriz, logrando que ésta sea de mejor calidad y más estética.

    Objetivo: Describir la anatomía microquirúrgica y los abordajes a la región temporal mesial (RTM), en relación a cavernomas de dicho sector. Materiales y Método: Cinco cabezas de cadáveres adultos, fijadas en formol e inyectadas con silicona coloreada, fueron estudiadas. Además, desde enero de 2007 a junio de 2014, 7 pacientes con cavernomas localizados en la RTM fueron operados por el autor. Resultados: Anatomia: La RTM fue dividida en 3 sectores: Anterior, medio y posterior. Pacientes: 7 enfermos con cavernomas de la RTM fueron operados por el autor. De acuerdo a la ubicacion en la RTM, 4 cavernomas se ubicaron en el sector anterior, 2 cavernomas se localizaron en el sector medio y 1 cavernoma se ubico en el sector posterior. Para el sector anterior de la RTM se utilizo un abordaje transsilviano-transinsular; para el sector medio de la RTM se utilizo un abordaje transtemporal (lobectomia temporal anterior); y para el sector posterior de la RTM se utilizo un abordaje supracerebeloso-transtentorial. Conclusión: Dividir la RTM en 3 sectores nos permite adecuar el abordaje en función a la localización de la lesión. Así, el sector anterior es bien abordable a través de la fisura silviana; el sector medio a través de una vía transtemporal; y el sector posterior por un abordaje supracerebeloso. PMID:26600986

Las expectativas de las pacientes son cada vez mayores, exigiendo resultados naturales y sin estigmas quirúrgicos. Todas las vías de abordaje clásicas, para la colocación de implantes mamarios, dejan cicatrices visibles. En mujeres con areolas de diámetro grande, es posible emplear un abordaje dentro de la areola, que deja una cicatriz oculta en su unión con el pezón. Se describe la técnica y posteriormente se discuten sus indicaciones, ventajas y desventajas.Augmentation mammoplasty has gained acceptance as a safe surgical procedure with fast recovery and a readily predictable outcome. Increasing patient expectations impose demands on natural appearance without signs of surgery. All standard incision areas for insertion of implant leave visible scars. For women with large areolar diameter, it is possible to leave a hidden scar at the aerola-nipple junction by conducting an intra- areolar approach. The technique is described and its intended application and advantages and disadvantages are discussed.

    Full Text Available In the course of investigations at Romuliana nine antler three-partite combs with a single row of teeth were found in the Late Roman horizons dating from the late 4th - mid 5th century. They were found in Tower 19, in the Palace II sector and in the Thermae sector. The combs can be classified as two types: three-partite unilateral combs with semicircular handle (Petković comb type VII and three-partite unilateral combs with triangular handle decorated with horse protomes (Petković comb type VI. Two groups of these finds were distinguished after more detailed analysis; the earlier one including specimens originating from the Chernyahov-Sîntana de Mureº culture and later one including specimens made under "barbarian"influence and produced in Romuliana. These finds confirm the continuity of settlement at Romuliana in the Late Roman period, from the final quarter of the 4th until the end of the 5th century and open up the question of the character of the settlement.

    The exophthalmos of Graves' disease remains a pathophysiologic and therapeutic puzzle. Its relation to the hyperthyroidism of Grave's disease is far from clarified. It is a common clinical observation that exophthalmos does not often relate temporally with the onset of hyperthyroidism. Furthermore, exophthalmos may occur in patients who have no evidence of thyroid disease. Pathologically, exophthalmos is characterized by marked lymphocytic infiltration of the retro-orbital muscles, with edema and mucopolysaccharide deposition. Recently, cellular immunity in response to retro-orbital antigens and abnormal humoral immunity are suggested for the pathogenesis of exophthalmos. We experienced 2 patients with hyperthyroidism and unilateral exophthalmos. The clinical and laboratory features of the patients are presented with review of articles, with emphasis on pathogenesis.

    Full Text Available El trabajo en la gestión para la reducción del riesgo por desastres, contempla diferentes elementos dentro de su estrategia, muchos de ellos de contenido técnico y otros de índole social; y para su ejecución y cumplimiento de los objetivos se requiere de esfuerzos interdisciplinarios, para poder hacer abordajes integrales. Por tanto, en este escrito se pretende hacer una reflexión en torno a la relación entre la gestión del riesgo y el aporte de la psicología como ciencia social, llamando desde ahí la atención sobre la importancia de considerar el factor psicosocial en las estrategias de reducción del riesgo. Para lo cual se hace un recorrido desde la concepción de la psicología, de la gestión del riesgo, para finalmente arribar a una mirada integradora como propuesta en el abordaje del riesgo, de las emergencias y los desastres The work in management to reduce the risk by disasters, includes different elements within the strategy, most of them of technical content and others of social nature.

Presentamos el caso de una paciente en edad postmenopáusica con diagnóstico anatomopatológico de tiroides lingual de gran tamaño y localización profunda en la base de la lengua que producía disfagia y dificultad respiratoria crecientes. Asimismo, planteamos un nuevo abordaje quirúrgico para la resección combinando cervicotomía media, pull-through lingual y glosotomía media. Se discuten las distintas pruebas complementarias para llegar a su diagnóstico y se revisan las diferentes técnicas quirúrgicas habitualmente empleadas en su tratamiento concluyendo con las ventajas del abordaje empleado en este caso.Lingual thyroid is an uncommon congenital disorder of thyroid gland development, resulting in a lack of descend of the gland from the foramen caecum to his normal prelaringeal location. In this paper we present a case of a postmenopausic patient presenting with a big size lingual thyroid deeply located in the base of the tongue, suffering increasing disphagia and respiratory impairment. For tumor resection, we chose a surgical approach combining a cervical submental incision, lingual pull- through and midline glossotomy. We discuss the different image studies recommended for proper diagnosis also reviewing the most common surgical techniques used for treatment, as compared with the approach we have described in this case.

    Prepubertal unilateral gynecomastia is an extremely rare condition. At present, its etiology and management strategy are not well known. Two unrelated prepubertal boys of ages 8 and 9 who presented with complaints of unilateral enlargement of breast tissue are reported. Physical examination, biochemical, hormonal and oncologic work-up findings were normal. Both patients were treated with peripheral liposuction successfully. Histopathological and immunohistochemical examinations showed benign fibroglandular gynecomastia and intensive (3+) estrogen receptor expression in 100% of periductal epithelial cells. Although an extremely rare and generally benign condition, patients with prepubertal unilateral gynecomastia should have a full endocrine and oncologic work-up. PMID:25541897

    The present authors report a case of unilateral traumatic oculomotor nerve paralysis which shows interesting CT findings which suggest its mechanism. A 60-year-old woman was admitted to our hospital with a cerebral concussion soon after a traffic accident. A CT scan was performed soon after admission. A high-density spot was noted at the medial aspect of the left cerebral peduncle, where the oculomotor nerve emerged from the midbrain, and an irregular, slender, high-density area was delineated in the right dorsolateral surface of the midbrain. Although the right hemiparesis had already improved by the next morning, the function of the left oculomotor nerve has been completely disturbed for the three months since the injury. In our case, it is speculated that an avulsion of the left oculomotor nerve rootlet occurred at the time of impact as the mechanism of the oculomotor nerve paralysis. A CT taken soon after the head injury showed a high-density spot; this was considered to be a hemorrhage occurring because of the avulsion of the nerve rootlet at the medial surface of the cerebral peduncle.

En general, aunque se han creado lenguajes cada vez más cercanos al lenguaje humano, la programación no resulta ser una materia intuitiva ni de fácil comprensión y, por lo tanto, suele tratarse de una asignatura con una alta tasa de deserción. En este contexto, se presenta una revisión de los métodos de enseñanza, el formato de ejercitación y el material utilizado en las materias iniciales de programación en la educación superior, tanto en universidades de los Estados Unidos como de la Argentina. A lo largo del trabajo se buscará determinar el estado de la cuestión, comparar los casos de las distintas universidades a fin de establecer qué aspectos de los distintos abordajes favorecen el proceso de la enseñanza y poder así realizar un esbozo de solución que apunte a disminuir los índices de deserción en las materias introductorias de programación.

    Agarwal, Shailesh; Pappas, Lisa; Agarwal, Jayant

    2017-01-01

    Utilization of bilateral mastectomy for unilateral breast cancer is increasing despite cost and surgical risks with conflicting reports of survival benefit. Current studies evaluating death after bilateral mastectomy have included patients treated both with breast conservation therapy and unilateral mastectomy. In this study, we directly compared breast cancer-specific death of patients who underwent bilateral or unilateral mastectomy for unilateral breast cancer using a matched cohort analysis. This was an observational study of women diagnosed with unilateral breast cancer from 1998 through 2002, using the Surveillance, Epidemiology, and End Results (SEER) database. A 4-to-1 matched cohort of patients was selected including 14,075 patients. Mortality of the groups was compared using Cox proportional hazards models for cause-specific death. A total of 41,510 patients diagnosed with unilateral breast cancer were included. Unilateral mastectomy was performed in 93% of patients, while bilateral mastectomy was performed in the remaining 7% of patients. When 4-to-1 matching was performed, 11,260 unilateral mastectomy and 2,815 bilateral mastectomy patients were included. Patients with bilateral mastectomy did not have a significantly lower hazard of breast cancer-specific death when compared with patients with unilateral mastectomy (hazard ratio: 0.92 vs 1.00, p =0.11). Bilateral mastectomy did not provide a clinically or statistically significant breast cancer-specific mortality benefit over unilateral mastectomy based on a matched cohort analysis of a nationwide population database. These findings should be interpreted in the context of patient preference and alternative benefits of bilateral mastectomy.

    Full text: In preparation for major thoracic surgery, physiotherapists have traditionally taught unilateral breathing exercises. There are no studies that prove that these exercises are effective This study was undertaken to demonstrate the effects of unilateral thoracic expansion exercises (TEE) using 99 Tc m -Technegas Ten physiotherapists were taught unilateral TEE to increase ventilation to the right lower lobe. Each subject underwent two separate Technegas ventilation studies using a single-breath technique, one with normal deep inspiration and the other during a right TEE. Dynamic and static images were acquired in the seated position for each ventilation study. Analysis was undertaken by dividing the lungs into 6 zones of equal height and calculating the relative ventilation of each zone and each lung. Seven subjects (70%) achieved significantly increased ventilation to the right lower zone, while 9 (90%) achieved greater ventilation to the right lung. Total lung ventilation was reduced during right TEE when compared with normal deep inspiration

    Full Text Available Fusion is a developmental anomaly which occurs due to a union of one or more adjacent teeth during morphodifferentiation of the dental germs. The prevalence of tooth fusion is estimated at 0.5%–2.5% in the primary dentition. These anomalies may be unilateral or bilateral and may affect either dentition although the deciduous teeth are more commonly affected. Early diagnosis of such condition is important because it may cause clinical problems, such as esthetic concerns, and caries. This report describes a case of unilateral fusion of the primary mandibular lateral incisor and canine and aims to evaluate any associated pathology.

    Neuromuscular disorders associated with hyperthyroidism have several variations in their clinical phenotype, such as ophthalmopathy, periodic paralysis, and thyrotoxic myopathy. We herein report an unusual case of thyrotoxic myopathy presenting as unilateral drop foot. Histopathological examinations of the left tibialis anterior muscle showed marked variation in the fiber size, mild inflammatory cell infiltration, and necrotic and regenerated muscle fibers with predominantly type 1 fiber atrophy. Medical treatment with propylthiouracil resulted in complete improvement of the left drop foot. This case expands the phenotype of thyrotoxicosis and suggests that thyrotoxicosis be considered as a possible cause of unilateral drop foot.

Precisamente, atender al lugar diferencial que ocupa el "hecho delictivo" en estos trabajos antropológicos llevará a situar en líneas de indagación alternativas, por un lado, el reciente trabajo realizado en Argentina por Daniel Míguez y, por otro, dos etnografías brasileñas ancladas en la ciudad de Rio de Janeiro - entre las que encontramos una clara continuidad -, los trabajos de Alba Zaluar y Marcos Alvito. En un último apartado, me detendré a señalar la fructífera relación, no reconocida explícitamente en las etnografías que reseñamos, que esta línea de trabajo desarrollada en Brasil puede tener con los trabajos de Michel Foucault (esa relación es más patente en otros autores, como Michel Misse, cuya producción también podría ser incluida en esta perspectiva. De este modo, pretendo llamar la atención sobre aquellos abordajes que si bien pueden ofrecer aportes valiosos sobre tal o cual cuestión puntual, permanecen ciegos a los mismos fenómenos que la criminología convencional ignora dado que comparten con ésta la construcción de un campo de estudio centrado en la "delincuencia".

    Full Text Available En la actualidad la funduplicatura laparoscópica tipo Nissen se considera el tratamiento quirúrgico de elección para la enfermedad por reflujo gastroesofágico (ERGE y su efectividad a largo plazo es mayor del 90%. Dentro de los factores predictores de buena respuesta clínica están la adecuada selección del paciente y la experiencia del cirujano. Sin embargo, la prevalencia de síntomas nuevos, persistentes y recurrentes posteriores al procedimiento antirreflujo puede ser de hasta un 30%. Las causas son múltiples pero en general se deben a una o más alteraciones en la anatomía y en la función esofagogástrica. Ante la persistencia de los síntomas posterior al procedimiento quirúrgico se debería de utilizar el término «falla». En el caso de que un paciente inicialmente manifieste control de sus síntomas y posteriormente estos reaparezcan, se pudiera emplear el término «disfunción». Por otra parte, ante el empeoramiento de los síntomas o la aparición de síntomas o situaciones clínicas que no existían antes de la cirugía, debe de considerarse una «complicación». La disfagia postoperatoria y los síntomas dispépticos son muy frecuentes y requieren un abordaje integral para poder determinar el mejor tratamiento posible. En esta revisión se detallan los aspectos fisiopatológicos, de diagnóstico y tratamiento de los síntomas y las complicaciones posteriores a la funduplicatura para el manejo de la ERGE.

  20. Unilateral vestibular loss impairs external space representation.

    Directory of Open Access Journals (Sweden)

    Liliane Borel

    Full Text Available The vestibular system is responsible for a wide range of postural and oculomotor functions and maintains an internal, updated representation of the position and movement of the head in space. In this study, we assessed whether unilateral vestibular loss affects external space representation. Patients with Menière's disease and healthy participants were instructed to point to memorized targets in near (peripersonal and far (extrapersonal spaces in the absence or presence of a visual background. These individuals were also required to estimate their body pointing direction. Menière's disease patients were tested before unilateral vestibular neurotomy and during the recovery period (one week and one month after the operation, and healthy participants were tested at similar times. Unilateral vestibular loss impaired the representation of both the external space and the body pointing direction: in the dark, the configuration of perceived targets was shifted toward the lesioned side and compressed toward the contralesioned hemifield, with higher pointing error in the near space. Performance varied according to the time elapsed after neurotomy: deficits were stronger during the early stages, while gradual compensation occurred subsequently. These findings provide the first demonstration of the critical role of vestibular signals in the representation of external space and of body pointing direction in the early stages after unilateral vestibular loss.

La selección de plantas RC1F1 se realizó con los marcadores moleculares SCAR SAB3 y SAS13, ligados a los genes Co-5 y Co-42 , respectivamente. En la evaluación genotípica de 1.271 plantas RC1F1, 608 amplificaron con SAB3 y 603 con SAS13. La segregación para cada marcador se ajustó a la razón 1:1 esperada en pruebas de chi-cuadrado (X2 = 2,38, P= 0,12 para SAB3 y X2 = 3,32, P= 0,07 para SAS13. Un total de 299 plantas RC1F1 amplificaron con ambos SCAR, ajustándose a la razón esperada (X2= 1,11, P= 0,78 y confirmando la segregación independiente. Estas plantas fueron seleccionadas para continuar el programa de mejoramiento, ya que se espera que porten los genes Co-5 y Co-42. Se logró implementar la selección asistida por marcadores para antracnosis, y acelerar la introducción y piramidación de genes de resistencia en fríjol de importancia económica en Colombia.

    The aim of the study was to resolve the issue of spaceflight-induced, adaptive modification of the otolith system by measuring unilateral otolith responses in a pre- versus post-flight design. The study represents the first comprehensive approach to examining unilateral otolith function following space flight. Ten astronauts participated in unilateral otolith function tests three times preflight and up to four times after Shuttle flights from landing day through the subsequent 10 days. During unilateral centrifugation, utricular function was examined by the perceptual changes reflected by the subjective visual vertical (SVV) and the otolith-mediated ocular counter-roll, designated as utriculo-ocular response (UOR). Unilateral saccular reflexes were recorded by measurement of collic vestibular evoked myogenic potentials (cVEMP). The findings demonstrate a general increase in interlabyrinth asymmetry of otolith responses on landing day relative to preflight baseline, with subsequent reversal in asymmetry within 2-3 days. Recovery to baseline levels was achieved within 10 days. This fluctuation in asymmetry was consistent for the utricle tests (SVV and UOR) while apparently stronger for SVV. A similar asymmetry was observed during cVEMP testing. In addition, the results provide initial evidence of a dominant labyrinth. The findings require reconsideration of the otolith asymmetry hypothesis; in general, on landing day, the response from one labyrinth was equivalent to preflight values, while the other showed considerable discrepancy. The finding that one otolith response can return to one-g level within hours after re-entry while the other takes considerably longer demonstrates the importance of considering the otolith response as a result of both peripheral and associated central neural processing.

    Full Text Available Introducción y Objetivo. Las quemaduras en las manos suponen un volumen total muy importante en la atención sanitaria. Prácticamente la totalidad de la población ha sufrido o sufrirá a lo largo de su vida una quemadura en sus manos. Afortunadamente, la inmensa mayoría no requerirá una atención especializada por parte de un cirujano plástico. Aún así, el impacto de los que sí precisan dicha atención es importante y debemos tener siempre planificado cómo actuar en cada situación. La función final que se obtenga de una mano quemada será de vital importancia, tanto si es la única zona del cuerpo afectada, como si entra en el contexto del gran quemado, y más en estos casos puesto que tendrá una gran repercusión positiva en su calidad de vida si se logra un resultado óptimo y/o funcional. El objetivo de este artículo es revisar nuestra experiencia como Unidad de Quemados en el tratamiento de la mano quemada y mostrar una serie de ejemplos de abordaje de las secuelas de quemaduras en manos que permita al paciente reincorporarse de forma completa a su actividad habitual. Material y Método. Revisamos los pacientes atendidos en nuestra Unidad entre 2012 y 2014, la afectación en manos, su epidemiología, distribución por variables, y revisamos varios casos de secuelas, algunos típicos y otros menos frecuentes. Resultados. Atendimos a un total de 307 pacientes, de los cuales 68 sufrieron quemaduras en 1 mano y 113 en las 2, requiriendo finalmente cirugía 155 manos. Del total, 39 pacientes provenían del ámbito laboral, de los cuales sufrieron quemaduras en manos 20, siendo en estos casos más frecuente la afectación de ambas manos que en los pacientes que no sufrieron accidentes laborales (4 afectados en una sola mano y 20 en ambas manos. Conclusiones. Nuestros pilares básicos se centran en: un diagnóstico preciso y precoz de profundidad, extensión y repercusiones; un tratamiento quirúrgico temprano y adecuado; un manejo

Se plantea la importancia de considerar las condiciones de producción de subjetividad que inciden en los modos de presentación de los niños y sus dificultades en diversas áreas. Asimismo se plantean cuestiones en torno a las instituciones involucradas en estos procesos de subjetivación como lo son la Familia, la Escuela y la Salud, con sus discursos, padecimientos y prácticas actuales. Se observan las estrategias de abordaje en psicología clínica enmarcadas en las prestaciones de salud mental, advirtiendo efectos reduccionistas sobre la compleja situación de los niños cuyas conductas se patologizan a la luz de las exigencias epocales. Se propone para la psicología clínica una concepción del diagnóstico como acto promotor de sentido nuevo y preventivo de estigmatización y exclusión. This paper provides some reflections on the clinical experience with children and their families today in Uruguay, taking some authors from various disciplines. The importance of considering the conditions involving the production of subjectivity that affects the way children express their difficulties in various areas, is raised. This paper also raises questions about the institutions involved in these processes of subjectification such as the Family, the School and the Health, with their current speeches, sufferings and practices. Clinical psychology approach strategies that are framed in mental health benefits are observed and the reductive effects on the complex situation of children whose behavior is pathologized in the light of current demands is taken into consideration. A conception of diagnosis as a promoter act of new meaning and as having a preventive effect on the stigmatization and exclusion is proposed for clinical psychology.

    Full Text Available A pesar de los cambios políticos, socio-económicos y demográficos habidos en los países occidentales en las últimas décadas, las estructuras simbólicas y los imaginarios colectivos en torno a las mujeres, su función social y la maternidad no han cambiado tanto. El orden patriarcal hoy en Occidente se configura como un patriarcado de consentimiento. En dicha estructura social la retórica ideológica representa la maternidad como una elección. Sin embargo, a través de los universos simbólicos que ofrecen los medios de comunicación de masas, la maternidad sigue perfilándose como un mandato imperativo para la construcción de la identidad femenina. En este estudio vamos a tomar como ejemplo la película Madre de alquiler, representación fílmica sobre la maternidad y las técnicas de reproducción asistida que refrenda el mandato patriarcal de la maternidad.

    We studied three patients who developed left unilateral punctate keratitis after suffering left-sided Wallenberg Syndrome. A complex evolution occurred in two of them. In all cases, neurophysiological studies showed damage in the trigeminal sensory component at the bulbar level. Corneal involvement secondary to Wallenberg syndrome is a rare cause of unilateral superficial punctate keratitis. The loss of corneal sensitivity caused by trigeminal neuropathy leads to epithelial erosions that are frequently unobserved by the patient, resulting in a high risk of corneal-ulcer development with the possibility of superinfection. Neurophysiological studies can help to locate the anatomical level of damage at the ophthalmic branch of the trigeminal nerve, confirming the suspected etiology of stroke, and demonstrating that prior vascular involvement coincides with the location of trigeminal nerve damage. In some of these patients, oculofacial pain is a distinctive feature. PMID:24882965

Sotos syndrome (cerebral gigantism) is a disorder of growth and development with characteristic facial changes and normal endocrine function. Ocular manifestations may also include megalocornea, iris hypoplasia, cataracts, megalophthalmos, strabismus, nystagmus, and retinal dystrophy. Case report. A 50 year-old man with the clinical features of Sotos syndrome presented with complaints of decreased vision in the left eye. Ophthalmologic examination revealed bilateral megalocornea, megalophthalmos, iris hypoplasia and transillumination defects, cataracts, and unilateral glaucoma. Intraocular pressure was lowered, and visual field loss was stabilized with topical medications. Sotos syndrome patients should be examined routinely to allow for early detection and treatment of potential ocular problems, including glaucoma.

    To study the clinical profile and presentation of children with unilateral cataract. In this hospital-based, observational, cross-sectional study, patients 15 years of age or younger who presented with unilateral cataract were recruited. Cases of cataract secondary to causes such as trauma or uveitis were excluded. Age at detection and presentation, distance from the treatment center, presenting complaints, cataract morphology, and biometry were noted for each case. A total of 76 patients were recruited. Most patients presented with complaints of leukocoria. Persistent fetal vasculature accounted for 27.6% of cases and was the most common identifiable cause of cataract in this study. Subsequently, patients were divided into two groups: no persistent fetal vasculature (control) and persistent fetal vasculature. A male predominance was noted in both groups. The mean age at detection was 27.58 ± 37.02 and 6.17 ± 8.42 months and the mean age at presentation was 55.613 ± 45.21 and 14.83 ± 17.75 months in the control and persistent fetal vasculature groups, respectively. In the persistent fetal vasculature group, a significant difference was noted in the axial length, keratometry, and corneal diameter between the affected and normal eyes (P = .027, .00176, and .0114, respectively). In the control group, this difference was observed only in keratometry readings (P = .0464). The mean distance traveled by patients to reach the treatment center was 211 km. Persistent fetal vasculature is an important and less identified cause of unilateral cataract. A significant delay is noted in the detection and presentation of unilateral cataract.

  1. Unilateral lung transplantation for pulmonary fibrosis.

    Science.gov (United States)

    1986-05-01

    Improvements in immunosuppression and surgical techniques have made unilateral lung transplantation feasible in selected patients with end-stage interstitial lung disease. We report two cases of successful unilateral lung transplantation for end-stage respiratory failure due to pulmonary fibrosis. The patients, both oxygen-dependent, had progressive disease refractory to all treatment, with an anticipated life expectancy of less than one year on the basis of the rate of progression of the disease. Both patients were discharged six weeks after transplantation and returned to normal life. They are alive and well at 26 months and 14 months after the procedure. Pulmonary-function studies have shown substantial improvement in their lung volumes and diffusing capacities. For both patients, arterial oxygen tension is now normal and there is no arterial oxygen desaturation with exercise. This experience shows that unilateral lung transplantation, for selected patients with end-stage interstitial lung disease, provides a good functional result. Moreover, it avoids the necessity for cardiac transplantation, as required by the combined heart-lung procedure, and permits the use of the donor heart for another recipient.

    This study was undertaken to determine whether unilateral hallux valgus progresses unilaterally and to evaluate the demographics, etiologies, and radiographic findings associated with symptomatic unilateral hallux valgus deformities. Patients treated for hallux valgus between January 2004 and December 2008 were identified, and of these, 33 patients with unilateral deformities were enrolled. Progression of deformities in normal feet were evaluated at last follow-up visit, and the clinical information and radiographic measurements of those with a deformed normal foot or an unchanged normal foot were compared. Thirty-three patients (3.4%) had a unilateral hallux valgus deformity on preoperative radiographs. The mean length of follow up was 4.7 years (range, 2.4-11). Twenty-four cases had no deformity of the normal foot at last follow-up (the unchanged group), but 15 cases had developed hallux valgus deformity (the deformed group). No significant intergroup differences were found in terms of metatarsus adductus angle (P = .412), Meary angle (P = .771), talocalcaneal angle (P = 1.000), or calcaneal pitch angle (P = .267). However, members of the deformed group were significantly younger at disease onset (P = .045), exhibited a curved first metatarsal head (P = .046), and had a larger initial hallux valgus angle (P hallux valgus was found to be over 97.3%, and significant differences were found between the deformed and unchanged groups in terms of age of onset, metatarsal head shape, and hallux valgus angle.

La inclusión de dichos contenidos en el aula expresó un giro didáctico –impulsado desde el currículum- en la medida que favoreció la revisión del peso de la geografía física en las clases, en los libros escolares y en la planificación anual del profesor. Propició el tratamiento de problemáticas en diferentes escalas, el reconocimiento de actores sociales y sus intereses, el papel del Estado y organizaciones civiles, despertando el genuino interés de los alumnos. Sin embargo, este proceso no estuvo ni está exento de preguntas, desafíos metodológicos y dificultades. Particularmente se registran tres debilidades: la abundancia de información proveniente de los medios masivos de comunicación e Internet que suele reemplazar la explicación de lo ambiental desde la geografía; la persistencia de la importancia asignada a la geografía física previo al análisis de un caso ambiental; ciertas limitaciones provenientes de la línea renovada para la enseñanza de temáticas ambientales en la escuela.

    To compare the effect of, and the rate of subsequent development of iatrogenic antielevation syndrome after, unilateral versus bilateral inferior oblique graded recession-anteriorization to treat unilateral inferior oblique overaction. Thirty-four patients with unilateral inferior oblique overaction were included in a randomized prospective study. Patients were equally divided into 2 groups. Group UNI underwent unilateral, group BI bilateral, inferior oblique graded recession-anteriorization. A successful outcome was defined as orthotropia, or within 2 ∆ of a residual hypertropia, in the absence of signs of antielevation syndrome, residual inferior oblique overaction, V-pattern, dissociated vertical deviation, or ocular torticollis. A successful outcome was achieved in 11 (64.7%) and 13 (76.5%) patients in groups UNI and BI, respectively (p = 0.452). Antielevation syndrome was diagnosed as the cause of surgical failure in 6 (35.3%) and 2 (11.8%) patients, in groups UNI and BI, respectively (p = 0.106). The cause of surgical failure in the other 2 patients in group BI was due to persistence of ocular torticollis and hypertropia in a patient with superior oblique palsy and a residual V-pattern and hypertropia in the other patient. The differences between unilateral and bilateral inferior oblique graded recession-anteriorization are insignificant. Unilateral surgery has a higher tendency for the subsequent development of antielevation syndrome. Bilateral surgery may still become complicated by antielevation syndrome, although at a lower rate. In addition, bilateral surgery had a higher rate of undercorrection. Further studies on a larger sample are encouraged.

    Full Text Available Introducción: La violencia física contra la mujer es un problema de salud pública y una necesidad sentida por la comunidad, que exige una respuesta desde los servicios de salud. El objetivo de esta investigación fue desarrollar un modelo de abordaje a partir del servicio de salud que permita la detección, apoyo y seguimiento de estos casos. Materiales y Métodos: Se realizó una investigación-acción en un servicio de primer nivel de atención. Participaron personal de salud. Inicialmente se realizó un diagnóstico situacional para evaluar: percepción de violencia física contra la mujer, calidad del servicio y organización funcional ante casos de violencia. Se desarrolló un modelo de abordaje para enfrentar este problema a partir de: formación del personal de salud, reorganización funcional del servicio de salud y diseño de herramientas de detección y seguimiento. Se evaluó la intervención a partir de indicadores operativos y evaluación de su impacto a corto plazo. Resultados: Se logró que el personal se capacite y empodere del problema; se introdujeron elementos operativos para la reorganización funcional de la unidad operativa: tamizaje para violencia intrafamiliar, flujograma de atención y hoja de seguimiento. En las tres semanas siguientes a la implementación de estos instrumentos, tres casos de violencia fueron detectados y abordados por el servicio de salud. Discusión y Conclusiones: La metodología de investigación-acción permitió que los actores se empoderen del problema de violencia física contra la mujer, diseñen y apliquen herramientas para abordarlo. Es necesaria una evaluación posterior para determinar su impacto. Cómo citar este artículo: Rivadeneira MF. Violencia física contra la mujer: una propuesta de abordaje desde un servicio de salud.

    Full Text Available Introducción y Objetivo: La Gangrena de Fournier es una fascitis necrotizante del perineo y genitales externos que presenta una morbi-mortalidad elevada debido a su diagnóstico tardío y a las comorbilidades comúnmente asociadas en estos pacientes. Terapias adyuvantes como la presión negativa y los sustitutos dérmicos, han mostrado eficacia en el tratamiento de pacientes con defectos complejos de tejidos blandos y forman parte de nuestro protocolo de tratamiento actual. El objetivo de este estudio es describir la utilidad de nuestro abordaje quirúrgico combinado en la Gangrena de Fournier. Material y método. Presentamos un trabajo retrospectivo en el que describimos 3 pacientes varones tratados por defectos complejos de tejidos blandos secundarios a Gangrena de Fournier mediante nuestro protocolo de tratamiento quirúrgico que comprende: una primera etapa de control de la herida mediante desbridamientos agresivos y terapia de presión negativa, seguido de una etapa de contemporización que combina la utilización de matriz dérmica y terapia de presión negativa, y por último una etapa de reconstrucción para dar cobertura final al defecto. Resultados. Los 3 pacientes presentaron compromiso extenso de la región perineal y de las regiones adyacentes incluyendo genitales externos y miembros inferiores. Todos fueron tratados con éxito mediante el abordaje que describimos, sin secuelas funcionales y manteniendo el contorno a la región. Conclusiones. El abordaje utilizado en nuestros 3 casos representó una alternativa terapéutica eficaz. La combinación de terapia de presión negativa y matriz dérmica nos permitió un manejo simplificado de la herida y una reconstrucción con mayor seguridad y mínima morbilidad mediante cierre primario de las heridas y avance de colgajos locales.

    Full Text Available La fase final de toda cirugía es la sutura y su cicatriz correspondiente y, frecuentemente, ésta es la única secuela visible de una intervención. La técnica LASH (cicatrización cutánea asistida por láser, estimula los mecanismos de reparación de la piel por efecto térmico, condicionando la calidad de la cicatrización. Estudios experimentales en ratones comparando los resultados obtenidos en heridas quirúrgicas radiadas con laser diodo 810 nm tras ser suturadas, con los obtenidos en igual tipo de heridas suturadas de manera convencional, han demostrado que se consiguen cicatrices mucho menos visibles cuando se practica el tratamiento con láser. La histología confirma, comparativamente, una notable aceleración del proceso cicatricial con modificación del TGFβ (Transforming Growth Factor-Beta directamente implicado en la reparación tisular, en los animales en los que la sutura fue asistida por láser. Igualmente, el análisis tensiométrico demostró mayor resistencia a la acción de estiramiento mecánico en estas heridas. Estudios clínicos en pacientes sometidos a dermolipectomia, reducción mamaria y estiramiento facial, demuestran que al tratar con LASH una parte o una de las líneas de sutura, los análisis realizados tanto por los pacientes como por cirujanos independientes a los 8 días, 3 meses y un año, evidencian resultados más favorables para la técnica láser, Las dosis eficaces determinadas para las fluencias láser están entre 80 y 120 J/cm². La técnica LASH es simple de efectuar, reproducible, rápida y ofrece una clara evidencia de que es posible reducir considerablemente la cicatriz, logrando que ésta sea de mejor calidad y más estética.Suture is the final stage of surgery and as a consequence, a scar is frequently the only visible effect after an operation.

El objetivo de este trabajo es calcular el coste por proceso de las TRA realizadas en un hospital público en 2003 y compararlo con los resultados de 1998 en el mismo centro. Métodos: El estudio se realiza en la Unidad de Reproducción Humana (URH del Hospital Universitario Virgen de las Nieves de Granada en 1998 y 2003. Partiendo de los costes totales de dicha unidad, y mediante una metodología de distribución de costes basada en la estructura de costes, calculamos el coste por proceso de las TRA realizadas en este centro, considerando los costes completos. Resultados: Entre 1998 y 2003, la actividad y los costes de la URH analizada evolucionan de forma distinta. El análisis de la actividad muestra la consolidación de técnicas, como la microinyección espermática (ICSI y la desaparición de otras (ciclo sin reproducción asistida e inseminación artificial conyugal intracervical. En todos los procesos, los costes unitarios por ciclo y por embarazo disminuyen en el período analizado. Conclusiones: Se han producido importantes cambios en la estructura de costes de las TRA de la URH-HUVN entre 1998-2003. Mientras algunos procesos desaparecen, otros se consolidan con una elevada actividad. Los avances técnicos y las innovaciones organizativas, junto con un «efecto aprendizaje», han alterado la estructura de costes de las TRA.Objectives: Most studies on the costs of assisted reproductive technologies (ART identify the total cost of the procedure with the direct cost, without considering important items such as overhead or intermediate costs.

Most states switched from requiring mutual consent to allowing unilateral or no-fault divorce between 1970 and 1985, while the national divorce rate more than doubled after 1965. According to the Coase theorem, however, the legal shift should have had no effect on divorce rates.

    The purpose of this study was to describe the clinical presentation, diagnostic evaluation, and surgical management of a llama with an ectopic ureter. Nine-month-old female llama. The diagnostic evaluation included the use of computed tomography and an excretory ureterogram to confirm and identify the location of the ectopic ureter. Surgical management involved a unilateral nephrectomy. Computed tomography is a valuable asset to diagnose the presence and terminal location of an ectopic ureter in llamas, and nephrectomy appears to be a viable procedure to resolve the subsequent urinary incontinence

    We briefly review the results of our paper LBNL-46775: We study certain solutions of left-unilateral matrix equations. These are algebraic equations where the coefficients and the unknown are square matrices of the same order, or, more abstractly, elements of an associative, but possibly noncommutative algebra, and all coefficients are on the left. Recently such equations have appeared in a discussion of generalized Born-Infeld theories. In particular, two equations, their perturbative solutions and the relation between them are studied, applying a unified approach based on the generalized Bezout theorem for matrix polynomials

    Patients with unilateral neglect have problems reporting, responding, or orienting to novel or meaningful stimuli that is presented to the side opposite to that of a brain lesion. This creates a serous problem in regards to daily living activities. However, the established methods for assessing and training of unilateral neglect patients have several deficits. Recently, virtual reality (VR) technologies have been used as an assessment and treatment tool for rehabilitation. Hence, this study designed a VR system to assess and train unilateral neglect patients. In addition, the suitability and feasibility of our VR system for unilateral neglect patients was verified.

    The memory loss associated with bilateral and nondominant unilateral ECT was assessed with verbal memory tests known to be sensitive to left temporal lobe dysfunction and with nonverbal memory tests known to be sensitive to right temporal lobe dysfunction. Bilateral ECT markedly impaired delayed retention of verbal and nonverbal material. Right unilateral ECT impaired delayed retention of nonverbal material without measurably affecting retention of verbal material. Nonverbal memory was affected less by right unilateral ECT than by bilateral ECT. These findings, taken together with a consideration of the clinical efficacy of the two types of treatment, make what appears to be a conclusive case for unilateral over bilateral ECT.

    Full Text Available La orbitotomía lateral sigue siendo en el momento actual la técnica quirúrgica de elección para la biopsia o extirpación de lesiones intraorbitarias laterales al nervio óptico, la biopsia del propio nervio óptico y la extirpación de la glándula lacrimal. Se han descrito múltiples incisiones cutáneas para llevar a cabo esta intervención; la más frecuentemente empleada por el momento es la incisión palpebral, que discurre a nivel de alguna arruga del párpado superior. Aunque los resultados obtenidos con esta incisión suelen ser aceptables, no está exenta de complicaciones, ni estéticas ni funcionales. Por esto, en los últimos años han ido apareciendo nuevas incisiones que intentan evitar estas complicaciones. Entre estas nuevas vías de abordaje a la pared lateral de la órbita se encuentra la incisión temporal. En los últimos 3 años, se ha intervenido en nuestro servicio a cuatro pacientes para llevar a cabo biopsia o extirpación de masas intraorbitarias mediante orbitotomía lateral, siempre a través de una incisión temporal. En todos los casos esta incisión permitió una amplia exposición del campo quirúrgico y la cómoda realización de la intervención, obteniéndose resultados estéticos y funcionales excelentes, y sin ninguna secuela ni complicación permanente. La complicación específica más frecuente de esta incisión es la paresia de la rama frontal del nervio facial. Una técnica de disección cuidadosa suele ser suficiente para evitarla. Todo esto hace que esta incisión, tal y como la describimos aquí, sea de elección para llevar a cabo la orbitotomía lateral, constituyendo en nuestro criterio una alternativa perfectamente válida y a tener en cuenta frente a las incisiones «clásicas», a las que llega a superar en muchos aspectos.The lateral orbitotomy it still the surgical technique of choice for biopsies or the removal of intraorbital lesions that are lateral to the optic nerve, for biopsies of

    2014-01-01

    To test for otolith asymmetries, several studies described horizontal translation of the body and head en bloc during fast vertical axis rotation. This stimulus causes one otolithic organ to rotate on-axis, and the other to experience centripetal acceleration. To test a new, more simple method of unilateral stimulation with head tilt and the body remaining on axis. During stationary and during 360 deg/s rotation, 12 healthy blindfolded subjects had their heads tilted 30 degrees sideways, positioning one otolithic organ on the axis of rotation after the other. The haptic subjective vertical (SV) was recorded several times by means of a manually adjustable rod. It was found that during stationary the SV tilted about 4 degrees on average in the direction of the head. During rotation, the SV tilted about 9 degrees on average. We therefore estimate the effect of eccentric otolith rotation to be 5 degrees on average. Tilt of the subjective vertical induced by head tilt during on-axis body rotation can provide a relatively uncomplicated alternative to test unilateral otolithic function as compared to body and head translation during rotation. Moreover, unlike eccentric rotation of the entire body, somatosensory cues are minimized by keeping the body fixed on axis and by subtracting the effect of head tilt per se.

    Full Text Available In the majority of patients with raised intracranial pressure, the papilledema is bilateral. Unilateral papilledema is rare in conditions causing intracranial hypertension, and it has been described in Foster–Kennedy syndrome and in some cases of idiopathic intracranial hypertension. It has never been reported in cerebral venous thrombosis. We report a young lady presenting with features of subacute onset of headache with seizures, on evaluation she had superior sagittal and bilateral lateral sinus thrombosis. The risk factors found on evaluation were Vitamin B12 deficiency and hyperhomocysteinemia. On optic fundus examination, she had swollen optic disc on the right side with normal fundus on the left side, confirmed with the orbital ultrasound B-scan and optic coherence tomography. Her magnetic resonance imaging showed features of raised intracranial pressure with thrombosis of the superior sagittal and bilateral lateral sinus thrombosis. She was treated with anticoagulation (heparin followed by oral anticoagulants, antiedema measures, and vitamin supplementation for hyperhomocysteinemia. She improved over time and was asymptomatic during follow-up. We discuss the possible mechanisms described in the literature for unilateral papilledema. This report highlights the need for carefully performing bilateral fundus examination so as not to miss the vision or life-threatening causes of a headache.

  13. Legal Permissibility of Unilateral Humanitarian Interventions

    Directory of Open Access Journals (Sweden)

    Petra Perisic

    2013-03-01

    Full Text Available The paper explores the status of unilateral humanitarian interventions in international law. The United Nations Charter prohibits the use of force, except in case of self-defense and the collective action authorized by the Security Council. The question is whether the non-existence of unilateral humanitarian intervention among these exceptions means that they are not in conformity with the Charter and if so, whether the right to such interventions exists as the part of customary law. The issue has become even more controversial after the adoption of the “responsibility to protect” principle. Findings of legal scholars on this issue differ significantly. This paper analyzes and interprets the Charter provisions in order to answer the question of compatibility of humanitarian interventions with the Charter and examines the state practice in order to conclude whether the customary law rule allowing the humanitarian intervention exists. The conclusion of the paper is that there is no evidence to support the contentions that interventions without the Security Council authorization are permissible, although there are elements which point to the possibility of the creation of customary law allowing them.

The subjects were six children whose ages at the time of MR imaging ranged from 8 months to 11 years. Their clinical and MR features were analyzed. All of the children were born between 38 and 42 weeks gestation, without any significant perinatal events. Spastic hemiplegia and epilepsy were observed in all of the patients, and mental retardation was observed in four. The MR findings included unilateral cerebral polymicrogyria associated with ipsilateral cerebral hemiatrophy and ipsilateral brain stem atrophy in all patients. The ipsilateral sylvian fissure was hypoplastic in four patients. These patients showed relatively homogeneous clinical and neuroimaging features. Although the additional clinical features varied according to the site and the extent affected by the polymicrogyria, this disorder could constitute a new relatively homogeneous clinical entity.

    The aim of this study was to improve the accuracy of puncture to the median vertebral body using the unilateral transpedicular approach on percutaneous vertebroplasty (PVP). We have developed and evaluated a simple puncture simulation method based on the puncture angle determined by preoperative computed tomography (CT). Two groups were evaluated. The first (group A) comprised 23 patients (34 vertebral bodies) who had undergone PYP without preoperative puncture simulation before May 2004, and the second group (group B) comprised 24 patients (39 vertebral bodies) who had undergone preoperative puncture simulation and PVP after May 2004. CT in the prone position was performed, and the puncture angle on CT (PAC) via the vertebral arch pedicle targeting the anterior one-third median site of the vertebral body was determined. Puncture was performed by targeting the isocenter established on a fluoroscopic monitor based on the PAC. Determinations were made of the success rate (SR) of the median puncture of the vertebral body, the effect of treatment using the visual analogue score, and the overall procedural time between groups A and B. The SR was 56% (19/34 vertebral bodies) in group A, and 97% (37/38 vertebral bodies), including only one vertebral body in which it was difficult to perform the unilateral approach on CT images, in group B, with the difference being significant by Student's t-test (P<0.001). Among patients with available follow-up data, the unipedicular and bipedicular approaches achieved adequate pain relief with mean decreases in pain severity of 5.1±2.6 and 5.9±2.8 respectively. No significant differences in the treatment effect between the two groups was observed (P=0.811). The overall procedure time per puncture was shorten for the simulation group (36.0 min) than for group A (73.1 min), as shown by regression analysis. The preoperative PAC determination for PVP under fluoroscopy increased the completion rate of PVP by the unilateral transpedicular

    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.

    Pattern-reversal and flash electroretinograms (ERG) and oscillatory potentials (OP) were recorded from 11 patients with unilateral glaucoma. All glaucomatous eyes had reduced amplitudes both compared to the opposite eye in the same patient and to reference values. In 10 of the 11 cases this reduction was below the level of normal variation. The difference in pattern-reversal ERG amplitude means from glaucomatous and opposite eyes was statistically significant. No differences were observed in flash ERGs or OPs. The histopathologic correlate to the visual field defects in glaucoma is retinal ganglion cell degeneration. The present electrophysiologic findings support the view, based on results from animal experiments, that the pattern-reversal ERG reflects ganglion cell activity.

    Migraine attacks exclusively felt in the face are very rare, the pain involving the territories supplied by the second and third branches of the trigeminal nerve. Two patients suffering from heminasal pain attacks accompanied with typical migrainous features and responsive to oral or intranasal triptans - but not to intranasal lidocaine or oxymetazoline. In one patient, the attacks could be precipitated upon slight touching on the tip of the nose, in the other attacks were preceded by the nasal sensation typically heralding sneezing. Migraine pain mostly develops within the innervation territory of the first branch of the trigeminal nerve, which includes the nose. Therefore, episodes of unilateral nasal pain with migrainous features could be considered a migraine with unusual topography (nasal migraine). Painful nasal attacks occasionally preceded by stimulation of trigeminal afferents in the nose, could be conceived of as migraine-tic syndrome.

    Following the notion of relative importance of the right hemisphere (RH) in creative thinking, we explored the possibility of enhancing creative problem solving by artificially activating the RH ahead of time using unilateral hand contractions. Participants attempted to complete the Remote Associates Test after squeezing a ball with either their left or right hand. As predicted, participants who contracted their left hand (thus activating the RH) achieved higher scores than those who used their right hand and those who did not contract either hand. Our findings indicate that tilting the hemispheric balance toward the processing mode of one hemisphere by motor activation can greatly influence the outcome of thought processes. Regardless of the specific mechanism involved, this technique has the potential for acting as a therapeutic or remedial manipulation and could have wide applications in aiding individuals with language impairments or other disorders that are believed to be related to hemispheric imbalances.

  5. Vestibular perception following acute unilateral vestibular lesions.

    Full Text Available Little is known about the vestibulo-perceptual (VP system, particularly after a unilateral vestibular lesion. We investigated vestibulo-ocular (VO and VP function in 25 patients with vestibular neuritis (VN acutely (2 days after onset and after compensation (recovery phase, 10 weeks. Since the effect of VN on reflex and perceptual function may differ at threshold and supra-threshold acceleration levels, we used two stimulus intensities, acceleration steps of 0.5°/s(2 and velocity steps of 90°/s (acceleration 180°/s(2. We hypothesised that the vestibular lesion or the compensatory processes could dissociate VO and VP function, particularly if the acute vertiginous sensation interferes with the perceptual tasks. Both in acute and recovery phases, VO and VP thresholds increased, particularly during ipsilesional rotations. In signal detection theory this indicates that signals from the healthy and affected side are still fused, but result in asymmetric thresholds due to a lesion-induced bias. The normal pattern whereby VP thresholds are higher than VO thresholds was preserved, indicating that any 'perceptual noise' added by the vertigo does not disrupt the cognitive decision-making processes inherent to the perceptual task. Overall, the parallel findings in VO and VP thresholds imply little or no additional cortical processing and suggest that vestibular thresholds essentially reflect the sensitivity of the fused peripheral receptors. In contrast, a significant VO-VP dissociation for supra-threshold stimuli was found. Acutely, time constants and duration of the VO and VP responses were reduced - asymmetrically for VO, as expected, but surprisingly symmetrical for perception. At recovery, VP responses normalised but VO responses remained shortened and asymmetric. Thus, unlike threshold data, supra-threshold responses show considerable VO-VP dissociation indicative of additional, higher-order processing of vestibular signals. We provide evidence of

    Objective: To evaluate and compare the two methods, electrocautery versus chemical cautery, for controlling unilateral anterior epistaxis and to identify the complications. Design: Randomized control trial. Place and Duration: This study was conducted in ENT Department PNS Shifa Hospital Karachi from August 2009 to June 2011. Patients and Methods: Ninety two cases with unilateral anterior epistaxis were divided using random number trials into two groups i.e. group A and group B containing 46 cases each. In group A electrocautery and in group B chemical cautery with 50% silver nitrate was done and the results were compared. Results: In this study 92 cases were divided randomly into two groups i.e. group A and group B containing 46 cases in each group. In group A 44 (95.6%) out of 46 cases were treated successfully with a single visit as an outpatient by electrocautery, the patients were called for follow up on the fifth day and then fortnightly for three months after the procedure, only 2 (4.3%) cases reported in first five days with mild recurrence of bleeding. In group B 42 (91.3%) cases out of 46 cases were treated successfully in a single visit and recurrence of bleeding occured in 4 (8.7%) cases who required a second visit during the first five days. There were no major complications found in either group except few complaints of post cauterization pain and mucosal inflammation observed slightly more in group B patients. Conclusion: Electrocautery and chemical cautery with 50% silver nitrate both are equally effective procedures to control anterior epistaxis if the bleeding point is visible and small. Both procedures are reliable and there are no major complications. Occasionally if the bleeding point in the anterior nasal septum is large then electrocautery may be a preferred option. (author)

    Full Text Available Purpose: Peripheral cone dystrophy is a subgroup of cone dystrophy, and only 4 cases have been reported. We present a patient with unilateral peripheral cone dysfunction and report the functional changes determined by electrophysiological tests and ultrastructural changes determined by spectral domain optical coherence tomography (SD-OCT. Case: A 34-year-old woman complained of blurred vision in both eyes. Our examination showed that her visual acuity was 0.05 OD and 0.2 OS. A relative afferent pupillary defect was present in her right eye. The results of slit-lamp examination, ophthalmoscopy, and fluorescein angiography were normal except for pallor of the right optic disc. SD-OCT showed a diffuse thinning of the retina in the posterior pole of the right eye. A severe constriction of the visual fields was found in both eyes but more in the right eye. The photopic full-field electroretinograms (ERGs were reduced in the right eye but normal in the left eye. The multifocal ERGs were severely reduced throughout the visual field except in the central area of the right eye. The multifocal ERGs from the left eye were normal. The pattern visual evoked responses were within the normal range in both eyes. She had a 5-year history of sniffing paint thinner. Results: Although the visual dysfunction was initially suspected to be due to psychological problems from the results of subjective tests, objective tests indicated a peripheral cone dysfunction in the right eye. The pathophysiological mechanism and the relationship with thinner sniffing were not determined. Conclusions: Our findings indicate that peripheral cone dysfunction can occur unilaterally. Electrophysiology and SD-OCT are valuable tests to perform to determine the pathogenesis of unusual ocular findings objectively.

    Full Text Available The principal symptoms of unilateral vocal fold paralysis are hoarseness and difficulty in swallowing. Dyspnea is comparatively rare (Laccourreye et al., 2003. The extent to which unilateral vocal fold paralysis may lead to respiratory problems at all - in contrast to bilateral vocal fold paralysis- has not yet well been determined. On the one hand, inspiration is impaired with unilateral vocal fold paralysis; on the other hand, neither the position of the vocal fold paralysis nor the degree of breathiness correlates with respiratory parameters (Cantarella et al., 2003; 2005. The question of what respiratory stress a patient with a vocal fold paresis can endure has not yet been dealt with.A 43 year-old female patient was suffering from recurrent unspecific respiratory complaints for four months after physical activity. During training for a marathon, she experienced no difficulty in breathing. These unspecific respiratory complaints occurred only after athletic activity and persisted for hours. The patient observed neither an increased coughing nor a stridor. Her voice remained unaltered during the attacks, nor were there any signs of a symptomatic gastroesophageal reflux or infectious disease. A cardio-pulmonary and a radiological examination by means of an X-ray of the thorax also revealed no pathological phenomena. As antiallergic and antiobstructive therapy remained unsuccessful, a laryngological examination was performed in order to exclude a vocal cord dysfunction.Surprisingly enough, the laryngostroboscopy showed, as an initial description, a vocal fold paralysis of the left vocal fold in median position (Figure 1. The anamnestic background for the cause was unclear. The only clue was a thoracotomy on the left side due to a pleuritis in childhood. A subsequent laryngoscopic examination had never been performed. Good mucosa waves and amplitudes were shown bilateral with complete glottal closure. Neither in the acoustic analysis, nor in the

Bajo esta perspectiva articulamosargumentos para fundamentar la concepción relacional de la vida encontraposición al abordaje esencialista o de simple listado de atributos. Estees muy utilizado para definir al ser vivo, mas necesariamente es pocoabarcador y esclarecedor.

Al contrario, la concepción relacionalde vida parte de la definición de que la vida es  adaptación flexible. Taldefinición emerge a partir de investigaciones realizadas sobre la vidaartificial y privilegia una metafísica de procesos al revés de una metafísicade sustancias. Entretanto, aunque el concepto relacional de la vida tengaventaja sobre la mayoria de los demás, tal vez no sea útil para ayudar adefinir mejor los límites y prerrogativas éticas y legales de intervencionesque amenacen vidas individuales, tales como el aborto y la eutanasia y noacarrear prejuicios o estabelecer privilegios de alcances sociales escasos.Concluimos con una apreciación jurídica del concepto relacional de la vida,especialmente la vida humana y su tutela en Brasil, informando lanaturaleza, los límites y la extensión de esa protección.

Presentamos un estudio prospectivo de 28 pacientes con ginecomastia de diferente grado, tratados mediante liposucción asistida por láser de Diodo de 1470 nm, previa sedación y con anestesia tumescente. El láser se programó a 15 Watios (W en emisión continua y se administraron 8 a 12 kilojulios (kJ por cada mama. No se realizaron escisiones de piel ni se emplearon drenajes. Se realizó valoración objetiva y subjetiva empleando la misma escala visual analógica (VAS completada por médicos y pacientes. Se tomaron fotografías antes y 6 meses después de la intervención, y se realizaron mediciones del perímetro torácico y del diámetro de las areolas. El seguimiento ecográfico de las áreas tratadas fue comparativo antes y 6 meses después del tratamiento. Para el estudio estadístico se empleó t de Student como test de contraste. No observamos complicaciones, como signos de isquemia o quemaduras cutáneas. La disminución del perímetro torácico y del diámetro de las areolas fue estadísticamente significativa. Tanto la valoración objetiva como la subjetiva alcanzaron resultados superiores al 90 %. Mediante la ecografía también se demostró disminución, estadísticamente significativa, de la banda de tejido graso subcutáneo (p < 0,05 al comparar las imágenes de antes y 6 meses después del tratamiento. La recuperación laboral se realizó en un promedio de 3 días. En conclusión, creemos que la liposucción láser-asistida es un método eficaz y reproducible, comprobado ecográfica y estadísticamente, que alcanza buenos resultados con menos trauma quirúrgico, lo que conlleva un alto grado de satisfacción por parte de los pacientes.

    Unilateral vocal fold paralysis with no preceding causes is diagnosed as idiopathic unilateral vocal fold paralysis. However, comprehensive guidelines for evaluating the defining characteristics of idiopathic unilateral vocal fold paralysis are still lacking. In the present study, we hypothesized that idiopathic unilateral vocal fold paralysis may have different clinical and neurologic characteristics from unilateral vocal fold paralysis caused by surgical trauma. Retrospective, case series study. Patients with unilateral vocal fold paralysis were evaluated using quantitative laryngeal electromyography, videolaryngostroboscopy, voice acoustic analysis, the Voice Outcome Survey, and the Short Form-36 Health Survey quality-of-life questionnaire. Patients with idiopathic and iatrogenic vocal fold paralysis were compared. A total of 124 patients were recruited. Of those, 17 with no definite identified causes after evaluation and follow-up were assigned to the idiopathic group. The remaining 107 patients with surgery-induced vocal fold paralysis were assigned to the iatrogenic group. Patients in the idiopathic group had higher recruitment of the thyroarytenoid-lateral cricoarytenoid muscle complex and better quality of life compared with the iatrogenic group. Idiopathic unilateral vocal fold paralysis has a distinct clinical presentation, with relatively minor denervation changes in the involved laryngeal muscles, and less impact on quality of life compared with iatrogenic vocal fold paralysis. 4.

Primeramente, entiendo la noción de imagen en sentido extendido a formas de apropiación social: las modas, consumos y gustos, diseños, tecnologías de comunicación y redes, etc. constituyen propiedades imaginales que intervienen sobre producciones normativas de prácticas sociales. Para concretar ese análisis general deben establecerse criterios acordes al objeto de estudio: se asume como objeto general de las ciencias sociales las relaciones (no el actor o el sistema, asumiendo las lógicas discursivas de lo social. Finalmente, se proponen especificidades metodológicas, entendiendo la interdisciplinariedad y la transdisciplinariedad como fundamentales. El trabajo sobre lo imaginal, es decir, acerca de la indiscernibilidad entre lo social y las imágenes, implica un abordaje de superposiciones de capas, cuestionando esencialismos y binarismos.

    Lesions of the thalamus and those extending into midbrain can cause various types of movement disorders such as dystonia, asterixis and ballism-chorea. Seizures are rare manifestation of thalamic disorder. Occurrence of seizures in bilateral thalamic infarct has been reported; but seizures in unilateral thalamic infarct have been reported very rarely. Literature review showed only single case of perinatal unilateral thalamic infarct presenting with seizures. We are reporting a unique case of convulsive seizure at the onset of unilateral thalamic infarct in an adult male, which has never been reported to the best of our knowledge.

It can occasionally be seen on the corneal surface. We report our clinical and histopathological findings in a case of unilateral corneal leukoplakia. Methods: A 26-year-old woman was referred to our hospital because of a white patch on her right cornea that continued to expand. She first noticed the white patch when she was 20 years old, and the white patch had expanded to cover the pupillary area affecting her vision. After plastic surgery on both eyelids for bilateral entropion to alleviate the pain caused by the eyelashes rubbing the cornea, the white corneal patch decreased in size. Because of this reduction, we performed surgery to remove the patch with microforceps under topical anesthesia. The plaque was removed easily and completely, and submitted for histopathological examination. Results: Histopathological examination showed that the specimen had characteristics of epidermis with a basal cell layer, spinous cell layer, granular cell layer, and horny layer with hyperkeratosis. She was diagnosed with leukoplakia of the corneal surface. The basic structure of the squamous cell layer was preserved, and there were no signs of metaplasia. Six months after the removal of the leukoplakia, no recurrence was seen and her corrected decimal visual acuity recovered to 1

    Full Text Available Unilateral-dependent pulmonary edema though reported in laparoscopic donor nephrectomies, has not been reported after laparoscopic non-donor nephrectomies. A 75-kg, 61-year-old man, a diagnosed case of right renal cell carcinoma was scheduled for laparoscopic nephrectomy. After establishing general anesthesia, the patient was positioned in the left-sided modified kidney (flank position. During the 5.75-hour procedure, he was hemodynamically stable except for a transient drop in blood pressure immediately after positioning. Intra-abdominal pressure was maintained less than 15 mmHg throughout the procedure. Blood loss was approximately 50 mL and urine output was 100 mL in the first hour followed by a total of 20 mL in the next 4.75 hours. Total fluid received during the procedure included 1.5 L of Ringer′s lactate and 1.0 L of 6% hydroxyethyl starch. After an uneventful procedure he developed respiratory distress in the postoperative period with a radiological evidence of dependent lung edema. Clinical and radiological improvement followed noninvasive ventilation, intravenous diuretics and oxygen therapy.

    Full Text Available Objectives. Asymmetric facial appearance may originate from abnormalities of facial musculature or facial innervation. We describe clinical features of congenital hypoplasia of depressor anguli oris muscle in a child. Material and Methods. Chart of a 10-month-old female referred to a tertiary care pediatric hospital for assessment of facial paralysis was reviewed. Data included relevant history and physical examination, diagnostic work up, and management. Results. The child presented with asymmetric movement of lower lip since birth. Asymmetry of lower lip was more pronounced when she smiled and cried. Rest of the face movement was symmetric. On examination, the face appeared symmetric at rest. The child had inward deviation of right lower lip when she smiled. Facial nerve function, as determined by frowning/forehead, wrinkling, eye closure, nasolabial fold depth, and tearing, was symmetric. Magnetic resonance imaging of the temporal bones and internal auditory canals were within normal limits. Echocardiogram did not show cardiac abnormality. Auditory brainstem response showed no abnormality. Conclusions. Congenital hypoplasia of depressor anguli oris is a rare anomaly that causes asymmetric crying face. Pediatricians and otolaryngologists need to be cognizant of cardiac, head and neck, and central nervous system anomalies associated with congenital unilateral hypoplasia of depressor anguli oris.

    Hemiplegic (or spastic unilateral) cerebral palsy accounts for about 30% of all cases of cerebral palsy. With a population prevalence of 0.6 per 1000 live births, it is the most common type of cerebral palsy among term-born children and the second most common type after diplegia among preterm infants. Many types of prenatal and perinatal brain injury can lead to congenital hemiplegia and brain MRI is the most useful tool to classify them with accuracy and to provide early prognostic information. Perinatal arterial ischemic stroke thus appears as the leading cause in term infants, whereas encephalopathy of prematurity is the most common cause in premature babies. Other causes include brain malformations, neonatal sinovenous thrombosis, parenchymal hemorrhage (for example due to coagulopathy or alloimmune thrombocytopenia) and the more recently described familial forms of porencephaly associated with mutations in the COL4A1 gene. In adjunction with pharmacologic treatment (botulinium neurotoxin injection), new evidence-based rehabilitational interventions, such as constraint-induced movement therapy and mirror therapy, are increasingly being used.

    Chia-Hsiang Fu

    Full Text Available Unilateral sinus disease (USD can sometimes be difficult to accurately diagnose before surgery. The application of nasal nitric oxide (nNO for USD diagnosis and its surgical outcome in USD has not been reported in the literature. We prospectively enrolled sixty-six USD patients who underwent endoscopic sinus surgery for fungal rhinosinusitis (n = 19, chronic rhinosinusitis (CRS without nasal polyps (n = 13, CRS with nasal polyps (n = 12 and sinonasal mass lesions (n = 22. nNO levels were measured preoperatively and at three and six months postoperatively. Correlations between nNO levels and potential clinical parameters, type of disease, disease severity, and disease-related quality of life (QOL were assessed. Unlike bilateral CRS, in USD, nNO levels did not correlate with disease severity or postoperative QOL improvements. Except for fungus group, there were no differences in nNO levels between lesion and non-lesion sides in all the other groups. nNO levels on both sides were significantly elevated six months postoperatively in all groups. Fungal rhinosinusitis patients had the lowest preoperative nNO levels, and a cutoff of 239.3 ppb had the best sensitivity (79.0% and specificity (87.2% for preoperative diagnosis. While preoperative nNO levels cannot serve as an alternative marker for disease severity of USD, they were lower in fungal rhinosinusitis patients than in other USD patients and may be useful for more accurate diagnosis prior to surgery.

    The purpose of this study was to describe the clinical characteristics of children with unilateral hearing loss (UHL), examine deterioration in hearing, and explore amplification decisions. Population-based data were collected prospectively from time of diagnosis. Serial audiograms and amplification details were retrospectively extracted from clinical charts to document the trajectory and management of hearing loss. The study included all children identified with UHL in one region of Canada over a 13-year period (2003-2015) after implementation of universal newborn hearing screening. Of 537 children with permanent hearing loss, 20.1% (108) presented with UHL at diagnosis. They were identified at a median age of 13.9 months (IQR: 2.8, 49.0). Children with congenital loss were identified at 2.8 months (IQR: 2.0, 3.6) and made up 47.2% (n = 51), reflecting that a substantial portion had late-onset, acquired or late-identified loss. A total of 42.4% (n = 39) showed deterioration in hearing, including 16 (17.4%) who developed bilateral loss. By study end, 73.1% (79/108) of children had received amplification recommendations. Up to 20% of children with permanent HL are first diagnosed with UHL. About 40% are at risk for deterioration in hearing either in the impaired ear and/or in the normal hearing ear.

    Rubio-Puchol, O; Garzón-Pastor, S; Salom-Vendrell, C; Hernández-Mijares, A

    Unilateral adrenal hyperplasia is a rare cause of primary hyperaldosteronism (around a 3%) that has surgical treatment. A case of a patient with hypertension resistant to conventional therapy in treatment with 7 drugs who presented with primary hyperaldosteronism due to unilateral adrenal hyperplasia is presented. A left adrenalectomy was performed, and the patient had a good clinical response, with no need of any drug after 2 years of surgery. Unilateral adrenal hyperplasia is a different entity and it is not an asymmetric variant of the bilateral adrenal hyperplasia. In the study of patients with primary hyperaldosteronism and imaging tests with absence of adenoma is a diagnosis that must be considered before cataloguing patients with bilateral adrenal hyperplasia and start a medical treatment, because unilateral adrenal hyperplasia would have a surgical resolution.

    Multifocal tumors within the same parotid gland are very rare. We treated 13 patients with multiple tumorous lesions within the unilateral parotid gland. We evaluated the multiple nodules by CT-sialography or magnetic resonance imaging (MRI). These imagings showed clearly two or more distinct nodular-appearing lesions. Recurrent pleomorphic adenoma (6 patients) was predominant, followed by Whartin's tumor (3 patients). The other lesions were two differential parenchymal tumors (polymorphous low grade adenoma/adenoma) within the same gland, a malignant lymphoma, a squamous cell carcinoma metastatic to the gland, and a tuberculous lesion. On palpitation, 9 of the patients had an unilateral tumor, one a palpable parotid mass in the gland, and the other four had two or more tumors in the unilateral gland. The patients with intra-parotid lymph node and metastatic lesions had extra-parotid cervical adenopathy. The clinical features and the differential diagnosis of the unilateral multiple tumors lesions of the parotid gland are discussed. (author)

    Full Text Available INTRODUCTION: Patients with vestibular hypofunction, a typical finding in peripheral vestibular disorders, show body balance alterations. OBJECTIVE: To evaluate the postural control of patients with vertigo and unilateral vestibular hypofunction. METHOD: This is a clinical cross-sectional study. Twenty-five patients with vertigo and unilateral vestibular hypofunction and a homogeneous control group consisting of 32 healthy individuals were submitted to a neurotological evaluation including the Tetrax Interactive Balance System posturography in eight different sensory conditions. RESULTS: For different positions, vertiginous patients with unilateral vestibular hypofunction showed significantly higher values of general stability index, weight distribution index, right/left and tool/heel synchronizations, Fourier transformation index and fall index than controls. CONCLUSION: Increased values in the indices of weight distribution, right/left and tool/heel synchronizations, Fourier transformation and fall risk characterize the impairment of postural control in patients with vertigo and unilateral vestibular hypofunction.

    Objective: To evaluate the common cause of unilateral exophthalmos and CT findings. Methods: The CT manifestations of 267 cases of unilateral exophthalmos were reviewed. 41 cases were confirmed by surgery and pathology. 68 cases were confirmed by biopsy. Diagnosis was made in 158 cases on the basis of typical history, laboratory findings and response to treatment. Results: The lesions were intraocular (10 cases), intraorbital (230) and periorbital lesions (27). The most common causes of unilateral exophthalmos included inflammatory pseudotumor (67 cases), pleomorphic adenoma or carcinoma of lachrymal gland (44), cavernous angioma (22), carotid cavernous fistula (20) and varices (18). The CT appearances were exophthalmos, intraocular or periorbital tumor, extraocular muscle hypertrophy. The contrast enhancement was variable without enhancement in necrotic areas. Conclusion: CT scan is valuable for diagnosis and displaying the structural change of unilateral exophthalmos. (authors)

    To analyze characteristics of mandibular movement in patients with unilateral mastication.
 Undergraduate students in oral medicine from Grade 2011 and 2012 in Wannan Medical College were enrolled for this study by cluster sampling method, which include 30 people with unilateral mastication and 30 people with bilateral mastication. The surface electromyogram (sEMG) of masseter muscle and anterovent of digastric muscle were recorded and the trajectory of mandibular incisor point was recorded simultaneously in the maximum opening and closing movement. The results were analyzed by SPSS 19.0 software.
 Average electrical peak of left anterior digastric muscle and right anterior digastric muscle in the unilateral chewing group was lower than that in the bilateral chewing group (P<0.05). The jaw tangent point trajectory was separate in the unilateral chewing group. There were significant differences at the opening type between the 2 groups. The vertical displacement and the sagittal displacement in the unilateral chewing group were significantly lower than those in the bilateral chewing group (P<0.01). There was significant positive correlation between the average peak potential of masseter muscle and displacement on the right side.
 Average electrical peak of left masseter muscle, left anterior digastric muscle, and right anterior digastric muscle decreases in the unilateral chewing group. Jaw tracking in most people deflects to the working side. Opening and closing jaw tracking is separate in 50% unilateral chewing individuals with the decreased opening degree. Unilateral chewing leads to changes in muscle performance accompanied by trajectory anomalies.

    Based on previous experience with prenatally diagnosed unilateral hydronephrosis, we found that the primary indications for surgical intervention should be symptoms or functional impairment of the hydronephrotic kidney. Nonoperative management of neonates without symptoms and with normal function...... of the affected kidney was proposed. However, the strategy of treatment after prenatally diagnosed hydronephrosis is still controversial. We studied 28 consecutive children with suspected unilateral pelviureteral junction obstruction and a normal contralateral kidney. The overall follow-up period varied between 2...

    Full Text Available El asma bronquial es una enfermedad inflamatoria crónica de las vías respiratorias cuya prevalencia está aumentando en el mundo. Actualmente no se dispone de un tratamiento curativo, y el objetivo principal de todo abordaje es el control de la enfermedad y la optimización de la calidad de vida de los pacientes. En este sentido, durante las últimas décadas se han estado implementando y evaluando programas de intervención complementarios a los tratamientos médicos convencionales. Gran parte de éstos consisten en intervenciones educativas o incluyen algún tipo de componente educativo. El objetivo del presente trabajo fue analizar las características y el impacto de las intervenciones educativas en el asma, a través de: a revisión actualizada sobre los diferentes tipos de intervenciones educativas desarrolladas e implementadas para el asma; b identificación de aspectos comunes a todas estas intervenciones; c análisis de los hallazgos de la investigación referidos a su impacto sobre la salud y la calidad de vida de los pacientes. Se concluye que las intervenciones educativas son efectivas para mejorar la salud y la calidad de vida de los pacientes con asma, y para reducir el uso y el costo de recursos sanitarios. Estos hallazgos señalan la importancia de incluir el componente educativo como parte esencial del abordaje integral de esta población clínica. Asimismo, la complejidad inherente al proceso educativo pone de manifiesto la necesidad del trabajo conjunto y complementario entre diferentes profesionales de la salud.Bronchial asthma is an inflammatory chronic disease of the respiratory tract whose prevalence is increasing worldwide.

    Full Text Available AIM: To compare the anterior segment morphology evaluated using ultrasound biomicroscopy (UBM in patients with clinical pseudoexfoliation syndrome (XFS in one eye and no clinical XFS in the fellow eye.METHODS: Thirty patients with unilateral XFS were included in the study. All patients underwent evaluation of their anterior segment using UBM with and without dilatation with 1% cyclopentolate. The anterior chamber depth (ACD, lens thickness (LT, anterior chamber angle (ACA, ciliary body thickness (CBT, scleral thickness (ST, trabeculae -ciliary processes distance (T-CPD, and iris-ciliary processes distance (I-CPD were measured using UBM scans. All results between the eyes with clinical XFS and their fellow eyes without clinical XFS were then compared.RESULTS: Before dilatation the eyes with XFS (4.350±0.531 mm were found to have a significantly thicker lens (P=0.002 than the eyes without XFS (4.238±0.540 mm. In addition after dilatation, the eyes with XFS (4.310±0.500 mm were found to have a significantly thicker lens than the eyes without XFS (4.160±0.480 mm (P=0.019. The average ACD, for the group with XFS, comparing pre-dilatation (2.616±0.349 mm and post-dilatation measurements (2.714±0.413 was found to be statistically increased (P=0.014. The average ACD, comparing pre-dilatation to post-dilatation measurements in patients without XFS (2.680±0.360, (2.720±0.500 was found to be statistically unchanged (P=0.450.DISCUSSION: Crystalline lenses tended to be thicker in the eyes with clinical pseudoexfoliation than their fellow eyes without pseudoexfoliation.

    2006-07-01

    The Unilateral Below Elbow Test (UBET) was developed to evaluate function in bimanual activities for both the prosthesis wearer and non-wearer. Nine tasks were chosen for each of four age-specific categories defined by development stages of hand function (2-4y, 5-7y, 8-10y, and 11-21y). Two scales, Completion of Task and Method of Use, were designed to rate performance. To measure reliability, four occupational therapists scored samples of videotaped UBET performances. For Completion of Task, an interval scale, agreement in scoring was measured with interclass correlation coefficients (ICC; n=9; five females, four males). For Method of Use, a nominal scale, chance-adjusted association was calculated with Cohen's kappa coefficients (interobserver n=198; 111 females, 87 males; intraobserver n=93; 56 females, 37 males). For Completion of Task, the average ICC was 0.87 for the prosthesis-on condition, and 0.85 for the prosthesis-off condition. ICCs exceeded 0.80 for eight out of nine tasks for the two older age groups, but for only five out of nine tasks in the younger age groups. Higher inter- and intraobserver kappa coefficients for Method of Use resulted when scoring children with their prostheses on versus off. The oldest age group had lower kappa values than the other three groups. The UBET is recommended for the functional evaluation of Completion of Task in children with unilateral congenital below elbow deficiency with and without their prostheses. Method of Use scoring can evaluate individuals for directed therapy interventions or prosthetic training.

    2015-04-01

    Full Text Available Hacia finales del siglo XX, se produce el reingreso del testimonio oral como fuente para la producción de conocimiento histórico, y de la Memoria al universo de la Historia como vía de acceso al imaginario de los sujetos; ello significó la posibilidad de dar cuenta de la multiplicidad de filiaciones identitarias mantenidas “al margen”, antes silenciadas, que pueden activarse en los sujetos en atención al “otro” en confrontación al cual se construye.La recuperación de las escalas de abordaje microsociales -lo local, lo barrial-, indispensable para el propósito de comprensión de los fenómenos culturales/simbólicos, permitió la organización de nuevos campos cuya adscripción disciplinar resulta dificultosamente definida.En este marco se involucran los estudios que abordan los mecanismos que contribuyen a la construcción de identidades socioterritoriales -a escala intraurbana- utilizando relatos biográficos y observando el espacio que los acontecimientos recordados ocupan en el establecimiento de relaciones simbólicas con el territorio habitado.Con los propósitos señalados, y a partir de una experiencia concreta, se propone la reflexión desde una matriz transdisciplinar sobre los alcances y limitaciones de la instancia de entrevista grupal como espacio de participación comunitaria y dispositivo de co-construcción de datos.Como resultado, se dispone de una mirada metodológica ampliada hacia dimensiones epistemológicas, que asisten a las reacciones que enfrentan tanto los acercamientos ingenuos que pretenden una suerte de desaparición del investigador para dar voz al “otro”, como los que asumen que el investigador interpreta las interpretaciones de los entrevistados desde una posición privilegiada y distante.

    Full Text Available Objetivos: describir las características de la nueva variante de queratoplastia lamelar anterior profunda, por abordaje desde la zona esclerolimbal empleando técnica de viscodisección y, analizar los resultados logrados en la cirugía experimental. Métodos: el procedimiento fue realizado en el Instituto Cubano de Oftalmología «Ramón Pando Ferrer», a 10 globos oculares humanos no útiles para trasplante. A través de incisión radial a nivel de la esclera adyacente al limbo se diseca hasta visualizar el tejido corneal más oscuro que indica el plano predescemético. Por el espacio creado, se avanza e inyecta viscoelástico desprendiendo controladamente la membrana de Descemet y endotelio. Resultados: en todos los ojos se pudo completar el procedimiento hasta lograr la disección de la membrana de Descemet. En ocho de ellos (80 %, no se produjo ninguna complicación intraoperatoria, en un ojo (10 %, hubo una perforación periférica de la membrana de Descemet, el proceder fue completado satisfactoriamente por otra incisión similar. En otro ojo (10 %, se produjo ruptura de la Descemet al inyectar viscoelástico para ampliar el desprendimiento. En el total de los casos se logró una disección que permitió aislar la membrana de Descemet transparente, con una superficie lisa y homogénea. El tiempo quirúrgico promedio fue de 18,4 minutos. Conclusiones: la técnica propuesta resultó segura y rápida en globos oculares enucleados. La disección se realiza en un área periférica de más seguridad. Este proceder también puede resultar de utilidad en la disección de la Descemet para la queratoplastia endotelial de la membrana de la Descemet.

Las circunstancias que introducen a niñas, niños y adolescentes en la institución judicial, conllevan diferentes niveles de violencia coexistentes. La familia, los sistemas político-institucionales y socio-culturales, entre otros, confluyen en sostener la eficacia de un orden de producción de subjetividades sustentado en una modalidad binaria de inclusión-exclusión, la cual se reproduce en acto al interior de las instituciones y del sistema de judicialización. Dichos imaginarios atraviesan las prácticas profesionales del psicólogo forense así como también, la práctica del investigador. Se requiere una mirada reflexiva al interior de esta última al contemplar que el propio investigador es simultáneamente actor social dentro del conjunto que se ha convertido en objeto de su investigación.The boarding of the binomial violence-childhood implies a critical reflection about the existence of a dissosciation between the law and the imaginary ones instituted in the referring thing to the subject.The circumstances that introduce girls, boys and adolescents in the judicial institution, entail different coexisting levels of violence. The family, the political-institutional and sociocultural systems, among others, comes together in maintaining the effectiveness of an order of production of subjectivities sustained in a binary modality of inclusion-exclusion, which reproduces in act to the interior of the institutions and the judicial system. Instituted imaginaries cross the professional practices of the forense psychologist as well as, the practice of the investigator. A reflective glance to the interior of this last one is required that the own investigator is simultaneously social actor within the set that has become object of its researcher.

  12. Proposal of unilateral single-flux-quantum logic gate

    1985-01-01

    A new type of single flux quantum logic gate is proposed, which can perform unilateral propagation of signal without using three-phase clock. This gate is designed to be built with bridge-type Josephson junctions. A basic logic gate consists of two one-junction interferometers coupled by superconducting interconnecting lines, and the logical states are represented by zero or one quantized fluxoid in one of one-junction interferometers. The bias current of the unequal magnitude to each of the two one-junction interferometers results in unilateral signal flow. By adjusting design parameters such as the ratio of the critical current of Josephson junctions and the inductances, circuits with the noise immunity of greater than 50% with respect to the bias current have been designed. Three cascaded gates were modeled and simulated on a computer, and the unilateral signal flow was confirmed. The simulation also shows that a switching delay about 2 picoseconds is feasible

    Full Text Available Gynecomastia is defined as the excessive development of breast tissue in males, which can occur as unilateral or bilateral. Although the overall prevalence of gynecomastia is 40%-65%, the prepubertal unilateral gynecomastia in the absence of endocrine abnormalities is unusual, with only a few case reports in literature. Idiopathic gynecomastia in prepuberty is benign but a diagnosis of exclusion. We here report two cases of healthy prepubertal boys aged 8.8 and 9.6 years old, respectively, presented with painful palpable mass in their unilateral breast. Breast tissue with glandular proliferation was confirmed on ultrasonography. Serum levels of estradiol, testosterone, and other laboratory findings were within normal range. They seem to have the prepubertal idiopathic gynecomastia but further follow-up to see their progression is needed.

  14. Unilateral perinephric pseudocyst of undetermined origin in a dog

    1992-01-01

    Unilateral perinephric pseudocyst of undetermined origin was diagnosed in a 131/2 year old dog with a history of recurrent urinary tract infections. A presumptive diagnosis of pseudocyst was based on radiographic and sonographic findings. In survey radiographs, asymmetrical unilateral renomegaly was seen. The mass was anechoic. There was absence of opacification of the mass during excretory urography. A celiotomy was performed for removal of the perinephric mass, and histologic review of this structure confirmed it to be a pseudocyst. Perinephric accumulation of fluid is a rare condition in domestic animals. Seven examples of perinephric pseudocysts have been previously reported in the cat. Predominant clinical findings include progressive abdominal distension and nonspecific signs of renal disease. The presence of unilateral or bilateral renomegaly is a characteristic radiographic feature. This clinical report describes the first case of perinephric pseudocyst diagnosed in the dog

    Full Text Available Proptosis, a common sign with a broad differential diagnosis, is defined as anterior displacement and protrusion of one or both orbital globes. Patients can present with varying degrees of chronicity, visual loss and associated symptoms. The etiology of acquired unilateral proptosis is diverse, ranging from benign to life-threatening. The causes of unilateral proptosis include traumatic, vascular, endocrine, inflammatory, infective and malignant. Breast carcinoma is the most common metastatic cause of proptosis; however, proptosis has never been reported as the initial manifestation of breast carcinoma. Our patient presented with unilateral proptosis secondary to an intraorbital lesion and histopathology of orbital lesion was suggestive of metastatic breast adenocarcinoma. She was later diagnosed to have primary breast carcinoma. We present this unusual case of a 56-year-old woman who presented with proptosis as the initial manifestation of a metastatic breast malignancy.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Um bloqueio simpático restrito durante raquianestesia pode minimizar as alterações hemodinâmicas. Teoricamente, o uso de soluções não isobáricas de anestésicos locais pode produzir anestesia unilateral e restringir a desnervação simpática a apenas um lado do corpo. A dose do anestésico local e o tempo que o paciente permanece em decúbito lateral para a realização da raquianestesia unilateral são desconhecidos. O presente estudo prospectivo investiga a incidência de raquianestesia unilateral utilizando bupivacaína a 0,15% preparada a partir de 1,5 ml de solução isobárica de bupivacaína adicionada de 25 µg fentanil, injetada através de agulha 27G tipo Quincke no paciente em decúbito lateral, com membro a ser operado voltado para cima. MÉTODO: Raquianestesia com 0,15% de bupivacaína mais fentanil foi realizada através da agulha 27G Quincke em 22 pacientes estado físico ASA I e II submetidos à cirurgias ortopédicas. A punção subaracnóidea foi realizada com o paciente previamente colocado com o lado a ser operado voltado para cima e foram retirados de 3 a 5 ml de LCR e injetados 5 ml da solução hipobárica na velocidade de 1 ml.15s-1. Bloqueios sensitivo e motor (picada de agulha e escala de 0 a 3 foram comparados entre os lados a ser operado e o contralateral. RESULTADOS: Os bloqueios motor e sensitivo entre o lado operado e o contralateral foram significativamente diferentes em todos os tempos em ambos os grupos. Raquianestesia unilateral foi obtida em 71% dos pacientes. Estabilidade hemodinâmica foi observada em todos os pacientes. Nenhum paciente desenvolveu cefaléia pós-raquianestesia. CONCLUSÕES: A bupivacaína hipobárica a 0,15% (7,5 mg associada ao fentanil proporciona um predominante bloqueio unilateral. Vinte minutos são suficientes para a instalação do bloqueio. As principais vantagens da raquianestesia unilateral são a estabilidade hemodinâmica, a satisfação do

    To determine the clinical efficiency and long-term outcomes between unilateral and bilateral stent insertion in patients with malignant hilar biliary obstruction. From August 2012 to February 2016, 63 consecutive patients with malignant hilar biliary obstruction were treated with unilateral or bilateral stent insertion at our center. The bilateral stents were inserted using the side-by-side technique. The clinical efficiency and long-term outcomes were compared between the two groups. Unilateral and bilateral stent insertions were successfully performed in 31 of 33 and 27 of 30 patients, respectively (P = 0.912). No procedure-related complication occurred. Clinical success was achieved in 29 of 31 patients in the unilateral stent group and in 26 of 27 patients in the bilateral stent group (P = 0.637). During the follow-up, re-obstruction of stent occurred in five patients in the unilateral stent group and in three patients in the bilateral stent group (P = 0.58). The significant differences were not observed in the stent patency time (368 vs. 387 days, P = 0.685) and survival (200 vs. 198 days, P = 0.751) between two groups. Based on the univariate and multivariate analyses, the independent risk factors for decreasing the survival time included higher Eastern Cooperative Oncology Group performance status (P = 0.018), higher alanine aminotransferase level (P = 0.009), and absence of anticancer treatment after stent insertion (P = 0.002). Compared to bilateral stent insertion for malignant hilar biliary obstruction, unilateral stent insertion can provide comparable clinical efficiency and long-term outcomes.

    Cervical spondylolysis, with or without spondylolisthesis, is a rare condition defined as a corticated cleft between the superior and inferior articular facets of the articular pillar. The defect occurs predominantly at C6, and is usually bilateral in up to two-thirds of cases. Multilevel involvement is uncommon, however, to date, no case of two consecutive levels of unilateral cervical spondylolysis on opposite sides has been reported. Here, we report a rare case of a patient affected by two consecutive levels of unilateral cervical spondylolysis at C5 and C6 on opposite sides in a 19-year-old male complaining of neck pain.

    Dorsal pancreatic agenesis is a very rare congenital anomaly. Unilateral renal agenesis, on the other hand, is a relatively common congenital anomaly, although its etiology is not fully understood. Renal and pancreatic embryologic development appears to be nonrelated. We report a case of a 34-year-old man who was referred to our hospital for evaluation of cholestasis and microalbuminuria. Ultrasound and magnetic resonance imaging examinations showed empty right renal fossa and absence of the pancreatic neck, body, and tail. Our case report is the second case of a dorsal pancreatic agenesis and unilateral renal agenesis in a young male patient.

    1987-01-01

    Using clinical presentation, angiography, computed tomography, and nuclear magnetic resonance imaging, 7 patients were identified who had strictly unilateral hemispheric infarction and unilateral cerebrovascular disease. In 6, cerebral blood flow measured by fluorine-18-fluoromethane inhalation and positron emission tomography was reduced in the contralateral hemisphere (p less than 0.05). Multiple regression analysis demonstrated a high correlation between contralateral flow reduction and the degree of flow impairment in the infarcted area (r = 0.941, p = 0.0014) but not with age, risk factor profile, blood pressure, PCO 2 , hematocrit, or duration of stroke. We conclude that transhemispheric diaschisis best explains the contralateral flow reduction seen in supratentorial ischemic stroke

It has been associated with various genitourinary abnormalities, including renal agenesis. We report a case of congenital unilateral absence of the vas deferens found incidentally during vasectomy in a patient with known unilateral renal agenesis. Case presentation: A 24-year-old male presented to our urology clinic requesting vasectomy. His past history was significant for left renal agenesis. Following successful right vasectomy, several attempts to locate the left vas deferens were unsuccessful. We diagnosed congenital unilateral absence of the vas deferens. Follow-up semen analysis showed azoospermia. Conclusion: As vasectomies are increasingly performed in outpatient settings, it is imperative that physicians be aware of this condition, which can be recognized by a simple physical exam. Recognition could prevent unnecessary surgery and prompt providers to investigate for associated abnormalities. Keywords: vas deferens, embryology, abnormalities, surgery

    Full Text Available Goal. To establish a reliable instrumental system for synchronized reactivation of a unilaterally paralyzed vocal fold and evaluate its functional feasibility. Methods. Unilateral vocal fold paralysis model was induced by destruction of the left recurrent laryngeal nerve (RLN in anesthetized dogs. With a micro controller-based electronic system, electromyography (EMG signals from cricothyroid (CT muscle on the ipsilateral side were recorded and used to trigger pacing of paralyzed vocalis muscles. The dynamic movement of vocal folds was continuously monitored using an endoscope, and the opening and closing of the glottis were quantified with customized imaging processing software. Results. The recorded video images showed that left side vocal fold was obviously paralyzed after destructing the RLN. Using the pacing system with feedback triggering EMG signals from the ipsilateral CT muscle, the paralyzed vocal fold was successfully reactivated, and its movement was shown to be synchronized with the healthy side. Significance. The developed unilateral laryngeal pacing system triggered by EMG from the ipsilateral side CT muscle could be successfully used in unilateral vocal fold paralysis with the advantage of avoiding disturbance to the healthy side muscles.

    Causes of unilateral hydrocephalus resulting from an obstruction at the Monro foramen include foraminal atresia, tumors, gliosis, contralateral shunting, and infectious and inflammatory conditions. However, few reports in the literature cite vascular lesions as the cause of the obstruction. To their knowledge, the authors present the first report of unilateral hydrocephalus occurring due to an abnormally enlarged thalamostriate vein independent of an arteriovenous malformation or developmental venous angioma. The condition was treated successfully by endoscopic septum pellucidum fenestration. A 28-year-old man was referred for evaluation due to a 10-year history of chronic headaches that worsened in severity over the past year. A CT scan of the head revealed unilateral right ventricular dilation. Cranial MR imaging with and without contrast administration showed a dilated right thalamostriate-internal vein complex without any evidence of associated arteriovenous malformation or venous angioma. Endoscopic exploration of the right lateral ventricle showed an enlarged subependymal thalamostriate vein obstructing the Monro foramen. An endoscopic fenestration of the septum pellucidum was performed, resulting in alleviation of the patient's symptoms. Abnormally enlarged venous structures may cause obstructive unilateral hydrocephalus and can be a rare cause of chronic, intermittent headaches in adults. Endoscopic fenestration of the septum pellucidum is an effective treatment.

    Full Text Available Unilateral Neglect Syndrome is one of the consequences of cerebral vascular accident (CVA generally following right parietal lobe lesion, leading to the impairment of perceptive visual, spatial and attention functions. The patient affected does not realize the environmental stimuli on the contralesional hemibody. Occupational therapy plays an important role in caring for this patient, seeking the recovery of perception, attention and social engagement. This study aimed to describe and evaluate the results of occupational therapy intervention and treatment in a single Unilateral Neglect Syndrome post CVA patient. Data were obtained from a survey of the patient’s medical records and interviews of his therapist and caretaker. The analysis of the patient’s medical records and his therapist’s report showed that the patient responded satisfactorily to treatment, presenting a decrease of the left unilateral neglect at the end of the study period. The favorable outcome of the patient outlined the relevance of evaluating the effects of Occupational Therapy interventions for clinical unilateral neglect syndrome.

    To identify the socioeconomic and psychosocial impacts of clinical treatment decisions for advanced unilateral intraocular retinoblastoma. Retrospective observational case series. institutional study at Alexandria Main University Hospital. records of 66 unilateral retinoblastoma cases treated from May 2005 to May 2013 were retrospectively reviewed. Sixty cases were eligible (International Intraocular Retinoblastoma Classification [IIRC] group C, D or E). two treatment groups were compared: enucleation vs. salvage treatment. Salvage treatment eyes were further subdivided based on IIRC group. Six socioeconomic parameters (financial burden, financial impact, psychological, social, medical and tumor impacts) were scored. Parameter scores ranged from 0 to 3, for overall score range 0 (no adverse impact) to 18 (severe adverse impact). derived Socioeconomic scores were correlated with treatment and outcomes.

    The aim of this study was to present the orthodontic treatment of a 15-year-old boy with a unilateral maxillary molar distalization system, called the zygoma-gear appliance. It consisted of a zygomatic anchorage miniplate, an inner bow, and a Sentalloy closed coil spring (GAC International, Bohemia, NY). A distalizing force of 350 g was used during the distalization period. The unilateral Class II malocclusion was corrected in 5 months with the zygoma-gear appliance. The maxillary left first molar showed distalization of 4 mm with an inclination of 3°. The maxillary premolars moved distally with the help of the transseptal fibers. In addition, there were slight decreases in overjet (-0.5 mm) and maxillary incisor inclination (-1°), indicating no anchorage loss from the zygoma-gear appliance. Preadjusted fixed appliances (0.022 × 0.028-in, MBT system; 3M Unitek, Monrovia, Calif) were placed in both arches to achieve leveling and alignment. After 14 months of unilateral distalization with the zygoma-gear appliance and fixed appliances, Class I molar and canine relationships were established with satisfactory interdigitation of the posterior teeth. Acceptable overjet and overbite were also achieved. This article shows that this new system, the zygoma-gear appliance, can be used for unilateral maxillary molar distalization without anchorage loss.

    Purpose To evaluate the prevalence and risk factors of strabismus in children undergoing surgery for unilateral or bilateral cataract with or without intraocular lens implantation. Methods Medical records of pediatric patients were evaluated from 2000 to 2011. Children undergoing surgery for unilateral or bilateral cataract with at least 1 year of follow-up were included. Children with ocular trauma, prematurity, or co-existing systemic disorders were excluded. The following data were evaluated: strabismus pre- and post-operation; age at surgery; post-operative aphakia or pseudophakia; and visual acuity. Results Ninety patients were included, 40% had unilateral and 60% had bilateral cataracts. Follow-up was on average 51 months (range: 12–130 months). Strabismus was found preoperatively in 34.4% children, and in 43.3% children at last follow-up. Strabismus developed in 46.2% of children who were orthotropic preoperatively, whereas 32.3% of children who had strabismus before surgery became orthotropic. Strabismus occurred after unilateral or bilateral cataract surgery in 63.9% and 29.6% children, respectively. At the last follow-up, strabismus was found in 46.7% of aphakic and 58.7% of pseudophakic children (P=0.283). Children who developed strabismus were generally operated at a younger age as compared with those without strabismus (mean of 25.9 vs 52.7 months, Pstrabismus. Conclusion Strabismus is a frequent complication after cataract surgery in children. Risk factors include unilateral cases and young age at surgery. No correlation was found between prevalence of strabismus and use of intraocular lens. Strabismus was more common in children with poor final visual acuity. PMID:27472210

    Full Text Available Context: Presurgical nasoalveolar moulding (PNAM is a non-surgical method of reshaping the cleft lip, alveolus, palate and the nose to minimize the severity of the cleft deformity, before primary cheiloplastyand palatoplasty. In this context, PNAM proves to be an invaluable asset in the management of unilateral cleft lip and palate. Aims: The study was conducted to evaluate the effi cacy of PNAM in the management of unilateral cleft lip and palate with the following objectives: (1 To assess and compare the degree of reduction in the size of cleft palate and alveolus (pre-PNAM and post-PNAM. (2 To evaluate and compare the improvement in columellar length and correction of columellar deviation (pre-PNAM and post-PNAM. (3 To assess the changes in the position of the alar base and the alar cartilages. Settings and Design: Prospective study. Subjects and Methods: A prospective study consisting of, which included 20 patients with complete unilateral cleft lip and palate was conducted. The age at the start of PNAM treatment of the infants ranged from 2 to 44 days of age reporting to our institute between December 2011 and August 2013. All the patients underwent PNAM therapy before primary cheiloplasty at 6 months of age; clinical parameters were assessed pre- and post-therapy using photographs and dental study models of the maxilla. Statistical Analysis Used: Student's t-test for paired comparisons. Results: Results of the study showed a promising reduction in the cleft size before the surgery, signifi cant improvement in nasal symmetry, including the columellar length on the cleft side. Conclusions: PNAM is a valuable adjunct to our surgical armamentarium in dealing with the challenges of primary closure of unilateral cleft lip and palate thereby enhancing the overall surgical outcome. The advantages of this method include the simplicity of the procedure and improving the quality of surgical repair, particularly in obtaining tension free muscle

  11. Unilateral incompatibility in Capsicum (Solanaceae): occurrence and taxonomic distribution.

    Unilateral incompatibility (UI) occurs when pollinations between species are successful in one direction but not in the other. Self-incompatible (SI) species frequently show UI with genetically related, self-compatible (SC) species, as pollen of SI species is compatible on the SC pistil, but not vice versa. Many examples of unilateral incompatibility, and all those which have been studied most intensively, are found in the Solanaceae, particularly Lycopersicon, Solanum, Nicotiana and Petunia. The genus Capsicum is evolutionarily somewhat distant from Lycopersicon and Solanum and even further removed from Nicotiana and Petunia. Unilateral incompatibility has also been reported in Capsicum; however, this is the first comprehensive study of crosses between all readily available species in the genus. All readily available (wild and domesticated) species in the genus are used as plant material, including the three genera from the Capsicum pubescens complex plus eight other species. Pollinations were made on pot-grown plants in a glasshouse. The number of pistils pollinated per cross varied (from five to 40 pistils per plant), depending on the numbers of flowers available. Pistils were collected 24 h after pollination and fixed for 3-24 h. After staining, pistils were mounted in a drop of stain, squashed gently under a cover slip and examined microscopically under ultra-violet light for pollen tube growth. Unilateral incompatibility is confirmed in the C. pubescens complex. Its direction conforms to that predominant in the Solanaceae and other families, i.e. pistils of self-incompatible species, or self-compatible taxa closely related to self-incompatible species, inhibit pollen tubes of self-compatible species. Unilateral incompatibility in Capsicum does not seem to have arisen to prevent introgression of self-compatibility into self-incompatible taxa, but as a by-product of divergence of the C. pubescens complex from the remainder of the genus.

    2010-10-01

    Retrospective review of the CT scans performed in a group of patients examined for a possible spondylolysis. To investigate whether there is an association between unilateral spondylolysis and facet joint tropism. Spondylolysis is a fatigue fracture of the pars interarticularis of great importance in sports injury. The demonstration of a unilateral spondylolysis is important because there is a potential for full healing if the athletic activity is modified, whereas bilateral spondylolysis frequently leads to established nonunion. Coronally orientated facet joints are known to predispose to spondylolysis by increasing the point loading of the pars interarticularis. The importance of this finding has not been investigated in unilateral spondylolysis. A review of patients with low back pain and a possible diagnosis of spondylolysis who were investigated with multislice CT was performed. The coronal orientation of the facet joints at L4/5 and L5/S1 was measured and comparison was done between those with and without a spondylolysis. The coronal angle of 140 facet joints in 35 patients was recorded. Of 35 patients, 23 had a spondylolysis which was unilateral in 12 patients. The facet joint angle was significantly more coronally orientated in the presence of a spondylolysis when compared with an intact pars (means, 53° and 43°, respectively; P spondylolysis, the facet joint was significantly more coronally orientated on the side of the spondylolysis (means, 52° and 45°, respectively; P spondylolysis. Asymmetric facet joints do increase the force through one side of the spine, with a unilateral spondylolysis occurring on the side of the more coronally orientated facet joint.

A través de la técnica de análisis de contenido cualitativo se analizan las versiones taquigráficas de los debates parlamentarios con el fin de responder los siguientes interrogantes: ¿cómo fue caracterizado el problema público al cual ambas leyes darían respuesta?, ¿cómo fue conceptualizada la misión de ambas leyes?, ¿en qué medida dicha definición implicó poner en entredicho las nociones de salud y enfermedad con relación a la cobertura de tratamientos de optimización o modificación corporal por parte del sistema público de salud? El proceso de sanción de ambas leyes implicó tensionar los conceptos de salud y enfermedad como categorías morales. En dicho marco emergió una noción ampliada del concepto de salud integral que incluyó los deseos reproductivos y corporales de los ciudadanos y ciudadanas.

    Full Text Available O presente estudo trata do caso de um paciente que apresentou incontinência do choro e hemiplegia direita por infarto ventroprotuberancial paramediano detectado pela RNM. O caráter circunscrito da lesão foi endossado pela normalidade dos potenciais evocados sômato-sensitivos e auditivos de curta-latência. Os episódios de choro desapareceram poucos dias depois do início do tratamento com doses baixas de imipramina. Discutimos o choro e riso patológicos como forma de incontinência da mímica resultante de desconexão límbico-motora, enfatizando a impropriedade de incluí-los na síndrome pseudobulbar, uma vez que dependem de correlatos anatômicos e funcionais distintos.A 64-year-old man presented with pathologic crying and right hemiplegia due to a unilateral pontine infarct from probable branch disease of the basilar artery. The circumscribed nature of the lesion was supported by MRI and short-latency evoked potentials. The weeping spells ceased after a few days of imipramine in low doses. Pathologic laughing and crying can be viewed as a limbic-motor disconnection syndrome, in which the faciovocal motor system is released from forebrain afferents carrying information of emotional content. The inclusion of pathologic laughing and crying in the syndrome pseudobulbar palsy is inaccurate and misleading, since each is related to distinct functional and anatomic systems intrinsic to the human brainstem.

Uno de los ejes priorizados en el análisis ha sido la construcción de procesos migratorios vinculados al territorio nacional, con especial atención a sujetos discursivos presentes y desplazamientos territoriales abordados; aspectos que se recuperan en este artículo mediante la selección de un caso específico que forma parte del corpus de la investigación. Para la aproximación propuesta nos hemos posicionado en el análisis crítico del discurso y, desde esa perspectiva, hemos recurrido a herramientas teórico-metodológicas del enfoque histórico del discurso (Wodak, de Cillia, Reisigl y Liebhart, 2009.

    To observe clinical manifestations, behavioral characteristics, and effects of rehabilitation on a patient with pusher syndrome and unilateral spatial neglect caused by right thalamic hemorrhage. Assessment of pusher syndrome was made by the Scale for Contraversive pushing (SCP), and unilateral spatial neglect syndrome was diagnosed using line cancellation, letter and star cancellation, line bisection tests and copy and continuation of graphic sequence test. Behavioral therapy, occupational therapy, reading training and traditional Chinese medicine methods were adopted for treatment of pusher syndrome and unilateral spatial neglect. The patient showed typical pusher syndrome and unilateral spatial neglect symptoms. The pusher syndrome and unilateral spatial neglect symptoms were significantly improved following rehabilitation treatments. Pusher syndrome and unilateral spatial neglect syndrome occurred simultaneously after right thalamic hemorrhage. Early rehabilitation therapy can reduce the symptoms of pusher syndrome and unilateral spatial neglect syndrome and improve motor function.

    Full Text Available It is known that early sensory deprivation modifies brain functional structure and connectivity. The aim of the present study was to investigate the neuro-functional organization of reading in a patient with profound congenital unilateral deafness. Using event-related potentials (ERPs, we compared cortical networks supporting the processing of written words in patient RA (completely deaf in the right ear since birth and in a group of control volunteers. We found that congenital unilateral hearing deprivation modifies neural mechanisms of word reading. Indeed, while written word processing was left-lateralized in controls, we found a strong right lateralization of the fusiform and inferior occipital gyri activation in RA. This finding goes in the same direction of recent proposals that the ventral occipito-temporal activity in word reading seem to lateralize to the same hemisphere as the one involved in spoken language processing.

  3. Entirely saturated unilateral smear of laser spot in CCD

    2013-01-01

    In the video of linear CCD camera being irradiated by 532 nm CW laser, the entirely saturated unilateral smear of laser spot was found. The smear area does not represent the distribution of laser. Since this smear lies merely in one side of laser spot, it can not be induced by light leaking or carriers blooming, and it may be induced by charge transfer loss. However, the feature that the smear area is entirely saturated can not be explained by the current constant model of charge transfer inefficiency. Based on the inner structure and operating principle of buried channel CCD, a new model of charge transfer inefficiency that varies with charge quantity is proposed, which can explain the entirely saturated unilateral smear of laser spot.

    2014-06-01

    Full Text Available The paper deals with the study of a quasistatic unilateral contact problem between a nonlinear elastic body and a foundation. The contact is modelled with a normal compliance condition associated to unilateral constraint and the Coulomb's friction law. The adhesion between contact surfaces is taken into account and is modelled with a surface variable, the bonding field, whose evolution is described by a first-order differential equation. We establish a variational formulation of the mechanical problem and prove an existence and uniqueness result in the case where the coefficient of friction is bounded by a certain constant. The technique of the proof is based on arguments of time-dependent variational inequalities, differential equations and fixed-point theorem.

    Unilateral condylar hyperplasia (UCH) is a disorder of unknown etiology mainly seen in growing patients, which results in facial asymmetry. High condylectomy alone or in association with orthognathic surgery can improve the occlusion and the facial aesthetics. Between 2005 and 2012, a total of 5 patients underwent high condylectomy for UCH using a piezoelectric cutting device. All patients were treated postoperatively with functional rehabilitation. The long-term follow-up showed that all patients had a satisfactory temporomandibular joint articular function associated with stable occlusion without any recurrence of further condylar growth. High condylectomy in the surgical treatment of unilateral UCH seems to be the procedure of choice in growing patients. The use of a piezoelectric cutting device allows a safe and less invasive high condylectomy.

    We present an unusual case of persistent generalized electroencephalography (EEG) suppression and right-sided clonic seizures in a male infant born at 40(+2) weeks\\' gestation, birthweight 3240g, with an isolated unilateral thalamic stroke. The EEG at 13 hours after birth showed a generalized very low amplitude background pattern, which progressed to frequent electrographic seizures over the left hemisphere. The interictal background EEG pattern remained grossly abnormal over the next 48 hours, showing very low background amplitudes (<10μV). Magnetic resonance imaging revealed an isolated acute left-sided thalamic infarction. This is the first description of severe global EEG suppression caused by an isolated unilateral thalamic stroke and supports the role of the thalamus as the control centre for cortical electrical activity.

    Given the bleak prospects for a global agreement on mitigating climate change, pressure for unilateral abatement is increasing. A major challenge is emissions leakage. Border carbon adjustments and output-based allocation of emissions allowances can increase effectiveness of unilateral action but introduce distortions of their own. We assess antileakage measures as a function of abatement coalition size. We first develop a partial equilibrium analytical framework to see how these instruments affect emissions within and outside the coalition. We then employ a computable general equilibrium model of international trade and energy use to assess the strategies as the coalition grows. We find that full border adjustments rank first in global cost-effectiveness, followed by import tariffs and output-based rebates. The differences across measures and their overall appeal decline as the abatement coalition grows. In terms of cost, the coalition countries prefer border carbon adjustments; countries outside the coalition prefer output-based rebates.(Author)

    Optic perineuritis is an uncommon inflammatory disorder that involves optic nerve sheath. Numerous case reports have been published on optic perineuritis in adults, the majority of whom had bilateral presentation. There are limited data on optic perineuritis occurring in pediatric patients. We report a teenager who presented with a unilateral sign that mimicked the presentation of optic neuritis. The orbit and brain magnetic resonance imaging confirmed features of unilateral optic perineuritis. She was treated with a high dose of corticosteroids for 2weeks, and her final visual outcome was satisfactory. No signs of relapse were noted during follow-up visits.

    Full Text Available Darier disease is an autosomal-dominant disorder of keratin production which leads to a loss in epithelial adhesion and abnormal keratinization. The clinical correspondence is keratotic papules grouped in sebaceous areas of trunk, scalp, forehead and flexures. It is a rare disease and the variant focused on here of unilateral segmental distribution following the lines of Blaschko is rarer still, considering the fact that this presentation counts for only 10% of this already uncommom disease and with only 40 cases being reported in English medical literature. Mutation in this gene is expressed in the skin and brain. The treatment of Darier disease can be challenging and is often difficult and sometimes unsatisfactory. Systemic retinoids are considered the drug of choice for treating Darier disease. However, their use is limited by potential side effects. We described the case a metalworker male with unilateral segmental Darier disease following Blaschko lines and we review the literature on this subject.

    Teeth and muscle play a very important role for occlusal equilibrium and function.when tooth loss begins ,it may also effect the function of muscle tissues. The thickness of masseter and anterior temporalis muscles were measured bilaterally in 30 healthy fully dentate adults and in 30 unilateral edentulous patients by using ultrasonographic imaging. All scans were carried out by the same radiologist to eliminate the inter-observer difference, using a real time scanner (Toshiba SSA -270A,Japan). A 7.5 MHz linear transducer was used. The effect of age, sex, duration of partial edentulism, unilateral chewing habits of the individuals to the muscle thickness were also evaluated. In all subjects,facial proportion index was also determined. Main purpose of this study was to compare and establish the differences of muscle thickness between dentate and edentulous side in unilateral partial edentulous patients with ultrasonography and to test whether the variation in the thickness of the muscle is related to the variation in the facial and morphology. Ultrasonography revealed a large variation in the thickness of the masseter and temporolis muscles in experimental and controlled groups ,both relaxed and contracted conditions.The thickness of muscles in females was less in both conditions.In experimental group, a high negative correlation was found between the thickness of the masseter muscle and Facial Proportion Index ( FPI) in the females ,however, the statistical analysis showed no significant difference in the males. Also a high negative correlation was found in female control group. There was no statistically significant relationship between unilateral chewing habits and muscle thickness .In this study the duration of partial edentulism did not affect the thickness of the muscle.Further research is required to study muscular atrophy for comparison with total edentulism.

    To describe a simple, minimally invasive method of ovariohysterectomy via a unilateral flank approach in guinea pigs, for use in routine desexing of healthy female guinea pigs or treatment of ovarian cysts. The subjects of this retrospective study were 41 client-owned guinea pigs submitted for routine desexing or treatment of ovarian cysts. They included 16 healthy female guinea pigs aged 8-12 months (Group 1), and 15 females aged from 9 months to 3 years (Group 2), and 10 females aged from 3 to 7 years (Group 3) with different-sized ovarian cysts. Prior to surgery, the animals received clinical examination, blood testing (complete blood count and serum biochemistry profile) and examination of the abdomen using ultrasonography, to assess the condition of the reproductive tract and ensure the guinea pigs were fit for surgery. Ovariohysterectomy was performed via a unilateral flank incision made close to the erector spinae muscle starting approximately 1 cm caudal to the last rib. Both ovaries, uterine horns, and the uterine cervix were localised, ligated, and dissected through this unilateral retroperitoneal incision. Ovariohysterectomy was successfully completed via a single flank incision in 38/41 (93%) guinea pigs. Three guinea pigs with ovarian cysts from Group 3, which were >6 years old died during surgery due to circulatory and respiratory failure under anaesthesia. In the remaining 38 cases, surgery proceeded without complications. A further two guinea pigs from Group 3 were reluctant to move or eat for the first 3 days after surgery but recovered after provision of supportive care. All 38 animals fully recovered and wound healing was normal. This is the first report of ovariohysterectomy via a unilateral flank incision in guinea pigs. This approach is a simple, minimally invasive and safe alternative to the midline or bilateral flank approaches currently used for surgery of the reproductive tract in guinea pigs.

    From a company perspective it is easier to develop a marketing strategy within a company than to arrange it in collaboration with others. Internal affairs can be controlled but agreements are left to the discretion of authorities. European competition policy suffers from a system failure discriminating against vertical agreements in favor of integrated organizations. Non-dominant companies should in principle be allowed to unilaterally decide its business strategy as there are alternatives. I...

E-mail: katia.barao@gmail.com Seventeen hyperthyroid cats with cervical palpable nodules were submitted to clinical and laboratorial examination and they were prepared to surgery. Unilateral thyroparathyroidectomy with parathyroid gland autotransplantation was performed. Concentrations of serum urea, creatinine, alkaline phosphatase, alanine aminotransferase, phosphorus, potassium, total thyroxine and hematologic profile were determined before and seven days after surgery. Blood samples for serum ionized calcium concentration were collected before and after surgery on days 1, 2, 7, 15, 21. All cats had ionized calcium concentration within the reference range before surgery. Serum calcium concentration fell significantly in all cats within 24 hours after surgery. Hypocalcemia occurred in two cats without clinical signs. Ionized calcium concentration decreased after surgery and returned to normal levels on day 7 postoperatively. The results of this study suggest that calcium concentration must be measured before surgery in cats submitted to thyroidectomy even if they are submitted to unilateral technique.

    Any process involving either the vagus nerve, its recurrent laryngeal branch or the external branch of the superior laryngeal nerve may cause paralysis of the vocal fold. The most common cause is neoplasm. Clinically, the patients often present with a hoarse, breathy voice as well as symptoms of aspiration. The following represents a unique case of unilateral vocal fold paralysis and dysphagia caused by a degenerative disease of the cervical spine, resluting in extrinsic compression of the recurrent laryngeal nerve.

    Full Text Available The present study investigates the hemispheric contributions of neuronal reorganization following early single-sided hearing (unilateral deafness. The experiments were performed on ten cats from our colony of deaf white cats. Two were identified in early hearing screening as unilaterally congenitally deaf. The remaining eight were bilaterally congenitally deaf, unilaterally implanted at different ages with a cochlear implant. Implanted animals were chronically stimulated using a single-channel portable signal processor for two to five months. Microelectrode recordings were performed at the primary auditory cortex under stimulation at the hearing and deaf ear with bilateral cochlear implants. Local field potentials (LFPs were compared at the cortex ipsilateral and contralateral to the hearing ear. The focus of the study was on the morphology and the onset latency of the LFPs. The data revealed that effects of hearing experience were more pronounced when stimulating the hearing ear. With respect to morphology of LFPs, pronounced hemisphere-specific effects were observed. Morphology of amplitude-normalized LFPs for stimulation of the deaf and the hearing ear was similar for responses recorded at the same hemisphere. However, when comparisons were performed between the hemispheres, the morphology was more dissimilar even though the same ear was stimulated. This demonstrates hemispheric specificity of some cortical adaptations irrespective of the ear stimulated. The results suggest a specific adaptation process at the hemisphere ipsilateral to the hearing ear, involving specific (down-regulated inhibitory mechanisms not found in the contralateral hemisphere.

  18. Unilateral or Reciprocal Climate Policy? Experimental Evidence from China

    2016-09-01

    Full Text Available The traditional political economy account of global climate change governance directs our attention to fundamental collective action problems associated with global public goods provision, resulting from positive or negative externalities as well as freeriding. The governance architecture of the 1997 Kyoto Protocol uses the traditional approaches of international diplomacy for addressing such challenges: legally binding commitments based on principles of reciprocity and (fair cost/burden sharing via formalized carbon-budgeting. Yet, the 2015 Paris Agreement has essentially abandoned this approach, as it now operates on the basis of internationally coordinated and monitored unilateralism. On the presumption that public opinion matters for government policy, we examine how citizens view this shift in climate policy from reciprocity to unilateralism, after many years of exposure to strong reciprocity rhetoric by governments and stakeholders. To that end, we fielded a survey experiment in China, the world’s largest greenhouse gas (GHG emitter. The results show that there is, perhaps surprisingly, strong and robust public support for unilateral, non-reciprocal climate policy. To the extent China is interested in pushing ahead with ambitious and thus costly GHG reduction policies, our results suggest that China can leverage segments of public support in order to overcome domestic obstacles to GHG mitigation policies.

    To evaluate the change in ocular function by eye in patients with unilateral pigmentary retinopathy. Longitudinal regression was used to estimate mean exponential rates of change in Goldmann visual field area (V4e white test light) and in full-field electroretinogram (ERG) amplitudes to 0.5- and 30-Hz white flashes in 15 patients with unilateral pigmentary retinopathy. Snellen visual acuity was assessed case by case. Mean annual rates of change for the affected eyes were -4.9% for visual field area, -4.7% for ERG amplitude to 0.5-Hz flashes, and -4.6% for ERG amplitude to 30-Hz flashes. All three rates were faster than the corresponding age-related rates of change for the fellow normal eyes (P = 0.0006, P = 0.003, P = 0.03, respectively). An initial cone ERG implicit time to 30-Hz flashes in affected eyes ≥ 40 ms predicted a faster mean rate of decline of visual field area and of ERG amplitude to 0.5- and 30-Hz flashes (P 35 years of age than in patients presenting at a younger age (P = 0.0004). The affected eye in unilateral pigmentary retinopathy shows a progressive loss of peripheral retinal function that cannot be attributed to aging alone and that is faster in eyes with a more prolonged initial cone ERG implicit time. Patients presenting at >35 years of age are at greater risk for losing visual acuity.

    The relationship of mandibular condyle dimensions and its association with unilateral posterior crossbite (UPXB) has been suggested in the literature. The purpose of this prospective study was to evaluate mandibular condyles on the left and right sides and between crossed and non-crossed sides in the sagittal and coronal planes, using cone-beam computed tomography (CBCT). Twenty CBCT images of 40 temporo mandibular joints (TMJs) in individuals in mixed dentition phase, which included 9 males (mean 7.9 years) and 11 females (mean 8.2 years), with unilateral posterior crossbite without premature contacts and functional mandibular shifts and with transverse maxillary deficiency. The criteria for sample exclusion included the presence of painful symptoms, facial trauma history, systemic diseases such as juvenile rheumatoid arthritis, mouth opening limitation (anomalies, and skeletal asymmetries that may result in TMJ disorders. Dimensional measurements of the condyles between the right and left sides and crossed and non-crossed sides in sagittal and coronal view were made. There was no significant difference between the measurements of the crossed and non-crossed sides in both sagittal and coronal view. These findings suggest that the presence of unilateral posterior crossbite in children with UPXB did not result in changes between the mandibular condyles in the right and left sides or between the crossed and non-crossed sides in the coronal or sagittal plane.

    To explore the surgical technique of a modified Onizuka cheiloplasty for repairing the unilateral cleft lip. 24 patients with unilateral cleft lip were repaired by modified Onizuka cheiloplasty. The rotation flap ended at the midpoint of nasal columella crease. A small triangle skin flap was formed above the vermilion border of the advancement flap. The small triangle flap was inserted to the medial side after the Cupid's bow was built. The skin of the flap C was denuded along the nasal columella crease and the muscle was sutured to the alar base for augmentation of nostril floor on the cleft side. The tip of the advancement flap was sutured at the midpoint of nasal columella crease and the skin of nasal floor was trimmed to hide the incision line around the nasal columella base. It was found that the Cupid's bow was rebuilt in a natural form and the configuration of the upper lip was reconstructed symmetrically. The long term follow up studies showed that the philtrum column was not disturbed by the small triangle flap and the nasal floor was rebuilt without obvious scars. The modified Onizuka cheiloplasty is an easy learning technique and efficient for repairing the unilateral cleft lip. This technique can satisfy the patients by reducing the length of scar as well as rebuilding a natural form of upper lip and nostril floor.

Diagnostic problems were noted in 24% of cases in Group A: eight patients with concomitant common upper aerodigestive tract infection, five patients with a concomitant condition liable to induce immunodepression and 11 patients in whom a malignant tumor occurred along the path of the ipsilateral vagus and inferior laryngeal nerves or in the ipsilateral paralyzed larynx. There was no recovery of vocal-fold motion beyond 51 months after onset of paralysis. The 5-year actuarial estimate for recovery differed significantly (Pvocal-fold paralysis. In non-traumatic vocal-fold paralysis in adult patients, without recovery of vocal-fold motion, a minimum three years' regular follow-up is recommended. Copyright © 2018 Elsevier Masson SAS.

    Clinicians and patients benefit when they have a clear understanding of how medical conditions influence patients' life experiences. Patients' perspectives on life with unilateral vocal fold paralysis have not been well described. To promote patient-centered care by characterizing the patient experiences of living with unilateral vocal fold paralysis. This study used mixed methods: surveys using the voice and dysphagia handicap indexes (VHI and DHI) and semistructured interviews with adults with unilateral vocal cord paralysis recruited from a tertiary voice center. Recorded interviews were transcribed, coded using a hierarchical coding system, and analyzed using an iterative inductive-deductive approach. Symptom domains of the patient experience. In 36 patients (26 [72%] were female, and the median age and interquartile range [IQR] were 63 years [48-68 years]; median interview duration, 42 minutes), median VHI and DHI scores were 96 (IQR, 77-108) and 55.5 (IQR, 35-89) at the time of interviews, respectively. Frustration, isolation, fear, and altered self-identity were primary themes permeating patients' experiences. Frustrations related to limitations in communication, employment, and the medical system. Sources of fear included a loss of control, fear of further dysfunction or permanent disability, concern for health consequences (eg, aspiration pneumonia), and/or an inability to call for help in emergency situations. These experiences were modified by the following factors: resilience, self-efficacy, perceived sense of control, and social support systems. Effects of unilateral vocal fold paralysis extend beyond impaired voice and other somatic symptoms. Awareness of the extent to which these patients experience frustration, isolation, fear, and altered self-identity is important. A patient-centered approach to optimizing unilateral vocal fold paralysis treatment is enhanced by an understanding of both the physical dimension of this condition and how patients

    OBJECTIVE Bilateral symptoms have been reported in 8%-35% of patients with sacroiliac (SI) joint dysfunction. Stabilization of a single SI joint may significantly alter the stresses on the contralateral SI joint. If the contralateral SI joint stresses are significantly increased, degeneration may occur; alternatively, if the stresses are significantly reduced, bilateral stabilization may be unnecessary for patients with bilateral symptoms. The biomechanical effects of 1) unilateral stabilization on the contralateral SI joint and 2) bilateral stabilization on both SI joints are currently unknown. The objectives of this study were to characterize bilateral SI joint range of motion (ROM) and evaluate and compare the biomechanical effects of unilateral and bilateral implant placement for SI joint fusion. METHODS A lumbopelvic model (L5-pelvis) was used to test the ROM of both SI joints in 8 cadavers. A single-leg stance setup was used to load the lumbar spine and measure the ROM of each SI joint in flexion-extension, lateral bending, and axial rotation. Both joints were tested 1) while intact, 2) after unilateral stabilization, and 3) after bilateral stabilization. Stabilization consisted of lateral transiliac placement of 3 triangular titanium plasma-sprayed (TPS) implants. RESULTS Intact testing showed that during single-leg stance the contralateral SI joint had less ROM in flexion-extension (27%), lateral bending (32%), and axial rotation (69%) than the loaded joint. Unilateral stabilization resulted in significant reduction of flexion-extension ROM (46%) on the treated side; no significant ROM changes were observed for the nontreated side. Bilateral stabilization resulted in significant reduction of flexion-extension ROM of the primary (45%) and secondary (75%) SI joints. CONCLUSIONS This study demonstrated that during single-leg loading the ROMs for the stance (loaded) and swing (unloaded) SI joints are significantly different. Unilateral stabilization for SI

    Ictal motor phenomena play a crucial role in the localization of seizure focus in the management of refractory focal epilepsy. While the importance of unilateral automatisms is well established, little attention is paid to the contralateral relatively immobile limb. In cases where automatisms mimic clonic or dystonic movements and in the absence of previously well-established signs, unilateral relative ictal immobility (RII) is potentially useful as a lateralizing sign. This study was carried out to examine the lateralizing value of this sign and to define its characteristics among patients of refractory focal epilepsy. VEEGs of 69 consecutive patients of refractory focal epilepsy who had undergone epilepsy surgery at our center over last four years were reviewed and analyzed for the presence of RII. Unilateral RII was defined as a paucity of movement in one limb lasting for at least 10s while the contralateral limb showed purposive or semi-purposive movements (in the absence of tonic or dystonic posturing or clonic movements in the involved limb). The findings were seen in the light of VEEG, radiological and nuclear imaging data, and with post-surgical outcome. Unilateral RII as a lateralizing sign was found in 24 of 69 patients (34.78%), consisting of both temporal and extra temporal epilepsy, with 100% concordance with VEEG and MRI data. All patients demonstrating this sign had a good post-surgical outcome. RII, when well characterized is a frequent and reliable lateralizing sign in patients of refractory focal epilepsy.

    Full Text Available Introduction: To describe clinical and electrophysiological features of a patient with unilateral Retinitis Pigmentosa (RP. Case: A 29-year-old female with a long history of progressive visual disturbance in the right eye has undergone multiple eye examinations during the past eight years. There was nothing noticeable in her past medical and ocular history. Comprehensive eye examinations were done in the first visit. All data was suggestive of right eye RP. Posterior segment fundal examination findings were: a pallor waxy disc, vessel attenuation, and extended pigmentary degeneration of the mid-peripheral retina. The left eye examination was normal. Comparing the automated 60 degree and 30 degree visual fields of both eyes obviously showed significant defects in the right eye visual field but normal in the left eye.  All of the probable infectious agents, which can cause similar ocular manifestations, were ruled out by serological tests. The standard photopic and scotopic electroretinographies were significantly reduced in amplitude in the right eye; however, they were normal in the left eye. Also, the standard Electro-Oculography (EOG results were the same as the Electro-Retinography (ERG ones in both eyes. Eye examinations were normal in other family members. Over an eight-year follow-up period, progressive deteriorating vision has gradually become more noticeable in the right eye. The left eye has been completely normal since.  This data was compatible with the Francois and Verriesr unilateral RP diagnostic criteria. Conclusion: Clinical signs and symptoms, a minimum of a five-year follow-up period, and confirmatory ERG and EOG are very helpful to diagnose andaffirm the case of unilateral RP.

    The aim of this study was to compare the unilaterality of subarachnoid block achieved with hyperbaric and hypobaric ropivacaine. The prospective, randomized trial was conducted in an orthopedics surgical suite. In all, 60 ASA I-III patients scheduled for elective total knee arthroplasty were included in the study. Group Hypo (n=30) received 11.25mg of ropivacaine (7.5mg.mL(-1)) + 2mL of distilled water (density at room temperature was 0.997) and group Hyper (n=30) received 11.25mg of ropivacaine (7.5mg.mL(-1)) + 2mL (5mg.mL(-1)) of dextrose (density at room temperature was 1,015). Patients in the hyperbaric group were positioned with the operated side down and in the 15° Fowler position, versus those in the hypobaric group with the operated side facing up and in the 15° Trendelenburg position. Combined spinal epidural anesthesia was performed midline at the L(3-4) lumbar interspace. Hemodynamic and spinal block parameters, regression time, success of unilateral spinal anesthesia, patient comfort, surgical comfort, surgeon comfort, first analgesic requirement time, and adverse effects were assessed. Time to reach the T10 dermatome level on the operated side was shorter in group Hyper (612.00±163.29s) than in group Hypo (763.63±208.35s) (phyperbaric and hypobaric ropivacaine (11.25mg) provided adequate and dependable anesthesia for total knee replacement surgery, with a high level of patient and surgeon comfort. Hypobaric local anesthetic solutions provide a high level of unilateral anesthesia, with rapid recovery of both sensory and motor block, and therefore may be preferable in outpatient settings.

    Background Good long-term visual acuity outcomes for children with dense congenital unilateral cataracts have been reported following early surgery and good compliance with postoperative amblyopia therapy. However, treated eyes rarely achieve normal visual acuity and there has been no formal evaluation of the utility of the treated eye for reading. Methods Eighteen children previously treated for dense congenital unilateral cataract were tested monocularly with the Gray Oral Reading Test, 4th edition (GORT-4) at 7 to 13 years of age using two passages for each eye, one at grade level and one at +1 above grade level. In addition, right eyes of 55 normal children age 7 to 13 served as a control group. The GORT-4 assesses reading rate, accuracy, fluency, and comprehension. Results Visual acuity of treated eyes ranged from 0.1 to 2.0 logMAR and of fellow eyes from −0.1 to 0.2 logMAR. Treated eyes scored significantly lower than fellow and normal control eyes on all scales at grade level and at +1 above grade level. Monocular reading rate, accuracy, fluency, and comprehension were correlated with visual acuity of treated eyes (rs = −0.575 to −0.875, p < 0.005). Treated eyes with 0.1-0.3 logMAR visual acuity did not differ from fellow or normal control eyes in rate, accuracy, fluency, or comprehension when reading at grade level or at +1 above grade level. Fellow eyes did not differ from normal controls on any reading scale. Conclusions Excellent visual acuity outcomes following treatment of dense congenital unilateral cataracts are associated with normal reading ability of the treated eye in school-age children.

    To investigate the pathogenesis, diagnosis, and treatment of unilateral gluteal muscle contracture. Between January 1990 and September 2009, 41 patients with unilateral gluteal muscle contracture were treated and the clinical data were retrospectively analysed. Among them, 24 were male and 17 were female with an age range from 6 to 29 years (mean, 12 years). Thirty-nine patients had a definite history of repeat intragluteal injection. The locations were the left side in 9 cases and the right side in 32 cases. The main clinical manifestations included lameness and abnormal gait. The medical examination showed pelvic oblique and relative inequality of lower limbs with a mean difference of 2.1 cm (range, 1.2-3.8 cm) in the distance form navel to malleolus medials. The X-ray films of pelvis showed outpouching trochanter of femur and pelvic oblique. The CT scans showed no abnormal finding except pelvic oblique and gluteal muscle contracture. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, followed by the skin traction of both legs and rehabilitation exercise. All incisions healed by first intention. Forty-one patients were followed up 1-20 years (mean, 5 years), and the signs of gluteal muscle contracture disappeared. After 1 year of operation, 34 patients had equal leg length, 5 patients had mild pelvic oblique, and 2 patients had obvious pelvic oblique. According to LIU Guohui et al. evaluation standard, the results were excellent in 33 cases, good in 6 cases, and poor in 2 cases with an excellent and good rate of 95.12% at 1 year after operation. Unilateral gluteal muscle contracture leads to pelvic oblique and inequality of lower limbs, and it can be cured with the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and

    Full Text Available Introduction: Teeth and facial muscles play a very important role in occlusal equilibrium and function. Occlusal derangement, seen in unilateral partially edentulous individuals, has an effect on masseter muscle anatomy and function. The present study aims to evaluate masseter muscle thickness in unilateral partial edentulism. Patients and Methods: Institutional ethics committee approval was obtained before the commencement of the study. The study involved patients who routinely visited the Department of Oral Medicine and Radiology, Sri Ramachandra University. The study sample included 27 unilateral edentulous patients (Group E and 30 controls (Group C. The masseter muscle thickness was evaluated using high-resolution ultrasound real-time scanner (linear transducer − 7.5–10 MHz at both relaxed and contracted states. Statistical Analysis Used: The results were analyzed using paired t-test and independent t-test. Duration of edentulism and muscle thickness was assessed using Pearson's correlation coefficient. Results: The study patients' age ranged between 25 and 48 years (mean – 36 years. The comparative evaluation of masseter muscle thickness between the dentulous and edentulous sides of experimental group was statistically significant (P < 0.05. However, no statistically significant difference in masseter muscle thickness was found between the dentulous side of control and experimental groups. The correlation between the duration of partial edentulism and muscle thickness was statistically insignificant. Conclusion: The study proves masseter atrophy in the edentulous side. However, since the difference is found to be marginal with the present sample, a greater sample is necessary to establish and prove the present findings as well as to correlate with the duration of edentulism. Further studies are aimed to assess the muscle morphology after prosthetic rehabilitation.

  16. Benign Episodic Unilateral Mydriasis in a Flight Nurse.

    2017-05-01

    Benign episodic unilateral mydriasis is one cause of anisocoria. This phenomenon is thought to be related to an imbalance between the sympathetic and parasympathetic nervous systems. There is a documented association with migraines, but asymptomatic cases have also been reported. A challenge with all cases is the level of investigation required to exclude more sinister causes of nervous system dysfunction. In a dynamic flight environment, additional considerations need to be made, such as varying light levels and use of night vision devices. A 27-yr-old woman on deployment to Afghanistan as a flight nurse presented to the role one clinic with right-sided mydriasis. The patient denied headache or any history of migraines. A dilated right pupil that was reactive to light was found on exam. Symptoms and exam findings resolved shortly after initial presentation. We consulted an ophthalmologist who requested patient transfer for review. He made a diagnosis of benign episodic unilateral mydriasis. There are a variety of causes for anisocoria. A thorough history and examination are required to avoid unnecessary investigations that may not be locally available in the more austere deployed military settings. From an operational perspective, the decision needs to be made regarding the maintenance of flight status. Consideration needs to be given to patient care capability when treating a flight nurse. In cases of rapid resolution such as this, removal from operational status is not reasonable should a clinician be confident of the diagnosis.Schiemer A.

    We report on an 18-month-old boy with unilateral left eye blinking as a single ictal manifestation without facial twitching. The clinical onset of this phenomenon was first recorded (as an occasional event) at age 3 months, and it was overlooked. By age 6 months, the child's blinking increased to almost daily occurrence in clusters: during blinking the infant showed intact awareness and occasional jerks in the upper limbs and right leg. A video-electroencephalography (video-EEG) documented clinical correlation with a focal pattern arising from the left occipital region, and brain magnetic resonance imaging (MRI) revealed severe brain damage, consisting in poroencephalic hollows and increased spaces in the convexities involving a large area of the left cerebral hemisphere. The boy was prescribed sodium valproate (30 mg/kg/d), resulting in drastic reduction of his clinical seizures. Follow-up to his current age documented good general status, with persistent partial right hemilateral seizures. The blinking progressively disappeared, and is no longer recorded. The pathogenic hypotheses of the unilateral ictal blinking include involvement of the ipsilateral cerebral hemisphere and/or the cerebellar pathways. Review of previous reports of unilateral eye blinking, arising from the ictal ipsilateral brain, revealed that different damaged regions may give rise to blinking ictal phenomena, likely via the trigeminal fibres innervating the subdural intracranial structures and the pial vessels in the ipsilateral affected brain. The eye blinking in the present child represents a further example of an ictal phenomenon, which is predictive of the damaged brain region. © EEG and Clinical Neuroscience Society (ECNS) 2014.

  18. Magnetic Vestibular Stimulation in Subjects with Unilateral Labyrinthine Disorders

    2014-03-01

    Full Text Available We recently discovered that static magnetic fields from high-strength MRI machines induce nystagmus in all normal humans, and that a magnetohydrodynamic (MHD Lorentz force, derived from ionic currents in the endolymph and pushing on the cupula, best explains this effect. Individuals with no labyrinthine function have no nystagmus. The influence of magnetic vestibular stimulation (MVS in individuals with unilateral loss of labyrinthine function is unknown and may provide insight into mechanism of MVS. These individuals should experience MVS, but with differences consistent with their residual labyrinthine function. We recorded eye movements in the static magnetic field of a 7T MRI machine in nine individuals with unilateral labyrinthine hypofunction, as determined by head impulse testing and vestibular-evoked myogenic potentials (VEMP. Eye movements were recorded using infrared videooculography. Static head positions were varied in pitch with the body supine, and slow-phase eye velocity (SPV was assessed. All subjects exhibited predominantly horizontal nystagmus after entering the magnet head-first, lying supine. The SPV direction reversed when entering feet-first. Pitching chin-to-chest caused subjects to reach a null point for horizontal SPV. Right unilateral vestibular hypofunction (UVH subjects developed slow-phase-up nystagmus and left UVH subjects, slow-phase-down nystagmus. Vertical and torsional components were consistent with superior semicircular canal excitation or inhibition, respectively, of the intact ear. These findings provide compelling support for the hypothesis that MVS is a result of a Lorentz force and suggest that the function of individual structures within the labyrinth can be assessed with MVS. As a novel method of comfortable and sustained labyrinthine stimulation, MVS can provide new insights into vestibular physiology and pathophysiology.

    A series of 60 children was studied (aged 0 to 10 years, 32 boys, 28 girls) with severe unilateral sensorineural hearing loss of unknown etiology. There were two peaks, at 0 and 6 years. In 19 children, hearing loss was identified during a conservative general health checkup for school or preschool children. In 21 children aged 0 years, 16 were suspected of hearing loss by newborn hearing screening. Temporal bone computed tomography scans were examined in 51 patients. Sixteen ears (31.4%) with hearing loss had inner ear and/or internal auditory canal abnormalities. In one patient, the anomaly was the presence of a bony wall dividing the internal auditory canal into two separate compartments associated with severe inner ear hypoplasia. Two patients had a common cavity. In one of these patients, the anomaly was revealed because of severe bacterial meningitis, and another was detected by newborn hearing screening. Six patients had a narrow internal auditory canal, 4 had a narrow internal auditory canal and hypoplastic cochlea, and 1 had a narrow internal auditory canal and cystic vestibule, and lateral semicircular canal dysplasia. Two patients had a cystic vestibule and lateral semicircular canal dysplasia. One case showed fluctuation of the hearing level in the contralateral ear with normal hearing during the observation period at an average of 20 months. The number of children whose unilateral hearing loss is detected early by newborn hearing screening has enormously increased. Strategies for follow-up, early intervention, and support for families are necessary for young children with unilateral hearing impairment. (author)

    The study of arctic or subarctic indigenous skin clothing material, known for its design and ability to keep the body warm, provides information about the tanning materials and techniques. The study also provides clues about the culture that created it, since tanning processes are often specific to certain indigenous groups. Untreated skin samples and samples treated with willow (Salix sp) bark extract and cod liver oil are compared in this study using both MRI and unilateral NMR techniques. The two types of samples show different proton spatial distributions and different relaxation times, which may also provide information about the tanning technique and aging behavior.

  1. Unilateral Carotid Body Resection in Resistant Hypertension

    2016-08-01

    Full Text Available Animal and human data indicate pathological afferent signaling emanating from the carotid body that drives sympathetically mediated elevations in blood pressure in conditions of hypertension. This first-in-man, proof-of-principle study tested the safety and feasibility of unilateral carotid body resection in 15 patients with drug-resistant hypertension. The procedure proved to be safe and feasible. Overall, no change in blood pressure was found. However, 8 patients showed significant reductions in ambulatory blood pressure coinciding with decreases in sympathetic activity. The carotid body may be a novel target for treating an identifiable subpopulation of humans with hypertension.

    Full Text Available Unilateral pure trigeminal motor nerve neuropathy is an extremely rare and unique condition, characterized by atrophy of the muscles, innervated by the motor branch of the trigeminal nerve. We report such a case in a 25-year-old male patient. The diagnosis was made on the basis of clinical and radiological examinations. Magnetic Resonance Imaging (MRI proved to be the key for establishing the diagnosis, which showed atrophy and fatty infiltration over the affected side of the muscles of mastication. We were unable to establish the cause of the condition even after performing a brain MRI.

    Abstract Anophthalmia is a rare ocular malformation. It is a genetically determined disorder and is typically associated with syndromes. However, sporadic nonsyndromic familial as well as non-familial cases of anophthalmia have also been reported. Non-syndromic familial cases are usually bilateral and have been attributed to autosomal recessive, autosomal dominant, and X-linked inheritance patterns. The authors hereby report a rare case of autosomal recessive unilateral anophthalmia in a patient with no other associated congenital anomaly. Patient was operated for craniopharyngioma. The clinical, radiological and intraoperative findings are discussed. PMID:27928292

    Noonan syndrome (NS) is an etiologically heterogeneous disorder caused by mutations in the RAS-MAPK signaling pathway. Noonan-Like/Multiple Giant Cell Lesion (NL/MGCL) syndrome is initially described as the occurrence of multiple gnathic giant cell lesions in patients with phenotypic features of NS. Nowadays, NS/MGCL syndrome is considered a variant of the NS spectrum rather than a distinct entity. We report the case of a 14-year-old female patient carrying a SOS1 mutation with a unilateral g...

    An instance of isolated unilateral temporalis muscle hypertrophy (reactive masticatory muscle hypertrophy with fiber type 1 predominance) confirmed by muscle biopsy with histochemical fiber typing and image analysis in a 62 year-old man is reported. The patient presented with bruxism and a painful swelling of the temple. Absence of asymmetry or other abnormalities of the craniofacial skeleton was confirmed by magnetic resonance imaging and cephalometric analyses. The patient achieved symptomatic improvement only after undergoing botulinum toxin injections. Muscle biopsy is key in the diagnosis of reactive masticatory muscle hypertrophy and its distinction from masticatory muscle myopathy (hypertrophic branchial myopathy) and other non-reactive causes of painful asymmetric temporalis muscle enlargement.

    Full Text Available Eagle's syndrome is not an uncommon condition, but less known to physicians, where an elongated styloid process or calcified stylohyoid ligament compresses the adjacent anatomical structures leading to orofacial pain. Diagnosis is made with appropriate radiological examination. Nonsurgical treatment options include reassurance, analgesia, and anti.inflammatory medications; and the surgical option includes a transoral or external approach. Here, we present a case report of a male patient, of age38 years, with a chief complaint of unilateral atypical orofacial pain on the right side of his face radiating to the neck region, for the last two months.

  8. Carbon leakage revisited. Unilateral climate policy under directed technical change

    Maria, Corrado Di; Van derWerf, E.

    2005-01-01

    This paper analyzes the consequences of unilateral climate policy in the presence of directed technical change. We develop a dynamic two-country model in which two otherwise identical countries differ in their environmental policy: one of the countries enforces a (binding) cap on emissions while the other does not. Focusing on carbon leakage, we show how, compared with a 'traditional' endogenous growth model, directed technical change will always lead to lower emissions in the unconstrained country. When clean and dirty goods are good substitutes, it may even be induced to reduce its emissions below the optimum level when both countries are unconstrained, so leakage is negative

    A variational formulation of the elastic beam problem with unilateral frictionless supports is presented. It is shown that the solution of this problem can be characterized as the solution of a variational inequality or as the solution of the constrained minimum of the total potential energy of the structure. THe finite dimensional counterpart of this variational formulation is obtained using the finite element method, and the Gauss-Seidel method with projection and overrelaxation can be used to obtain an approximate solution. In order to show the numerical performance of the present approach some numerical examples are also presented. (Author) [pt

    Full Text Available A 67-year-old woman presented with metamorphopsia in the right eye. Leopard mottling was seen temporal to the fovea oculus dexter with corresponding hyper- and hypo-autofluorescent lesions on fundus autofluorescence. Spectral domain-optical coherence tomography revealed hyperreflective dots in the retinal pigment epithelium and choroid with subretinal fluid (SRF. Intravitreal bevacizumab was administered with which SRF resolved, albeit with increase in the areas of mottling. The patient was diagnosed to have metastatic ductal carcinoma of the right breast. It is important to bear in mind that the well-known entity of bilateral diffuse uveal melanocytic proliferation can rarely present unilaterally.

    Full Text Available In the literature have been reported around fifty cases of lumbosacral dislocations; treated most bilateral facet dislocations. We report the case of a female 42 year old with unilateral lumbosacral facet dislocation of one month duration after accident. Circumferential instrumented fusion L5-S1 with interbody cage and pedicle screws L5-S1 was performed.   The lumbosacral dislocation is a rare injury that occurs due to the combination of a high-energy mechanism predisposing anatomical factors. Recent publications advocate the surgical reduction and stabilization with instrumentation as standard treatment.

    Full Text Available The aim of this study was to detect possible differences in the EMG (electromiography activity, chewing rate (CR, cycle duration (CD and preferred chewing side (PCS between children with and without unilateral posterior crossbite. Thirty-seven children aged from 7 to 10 years were selected from the clinic of the Department of Pediatric Dentistry, Piracicaba Dental School, Brazil, and divided into two groups: unilateral posterior crossbite (UPCB group, n = 17, and normal occlusion (NOccl group, n = 20. The PCS was determined using a visual spot-checking method. The EMG activity was recorded during mastication, and two chewing sequences of 20 s were evaluated to establish each subject's CR (cycles/sec and CD. UPCB and NOccl groups did not have a PCS. The EMG activity and the cycle characteristics did not differ between the groups. The correlations between CD, CR and EMG activity were statistically significant for the masseter and anterior temporalis muscles only in the NOccl group, in which there was also a significant correlation between the EMG activity of masseter and anterior temporalis. In conclusion, these findings suggest that although children with and without UPCB presented a bilateral masticatory pattern with similar CR and CD, balanced EMG activity of masseter and anterior temporalis muscles was observed only in the NOccl group. These results indicate that in children, UPCB can alter the coordination of masticatory muscles during mastication.

    Document the use of transcanal labyrinthectomy to treat disabling attacks of vertigo after unilateral cochlear implantation. A 46-year-old woman with severe-profound bilateral sensorineural hearing loss secondary to enlarged vestibular aqueducts underwent cochlear implantation for her right ear with a Nucleus Freedom device. The surgery was uneventful, and postoperative imaging confirmed that the electrode was positioned properly. She developed episodic vertigo 10 to 14 days after the implant surgery, which failed to improve with aggressive vestibular rehabilitation therapy. Plugging of the round window for possible perilymphatic fistula did not relieve her symptoms. Right transcanal labyrinthectomy supplemented by filling the vestibule with gentamicin-soaked Gelfoam and then a customized vestibular rehabilitation program. Comparison of vestibular symptoms and cochlear implant performance before and after transcanal labyrinthectomy. The patient had immediate relief of symptoms, and the function of the cochlear implant was not adversely affected. Transcanal labyrinthectomy may be an effective method to ablate the vestibular end organ after unilateral cochlear implantation. It can offer relief of disabling vertigo without adversely affecting the performance of the implant.

    2008-01-01

    To determine whether ipsilesional motor skills, which have been related to independent functioning, are present chronically after unilateral stroke and are more common in people with apraxia than in those without apraxia. Observational cohort comparing the performance of an able-bodied control group, stroke patients with left- or right-hemisphere damage matched for lesion volume, and left-hemisphere stroke patients with and without ideomotor limb apraxia. Primary care Veterans Affairs and private medical center. Volunteer right-handed sample; stroke patients with left- or right-hemisphere damage about 4 years poststroke; a control group of demographically matched, able-bodied adults. Not applicable. Total time to perform the (1) Williams doors test and the (2) timed manual performance test (TMPT), which includes parts of the Jebsen-Taylor Hand Function Test. Ipsilesional motor deficits were present after left- or right-hemisphere stroke when using both measures, but deficits were consistently more common in patients with limb apraxia only for the TMPT. These findings add to a growing literature that suggests that ipsilesional motor deficits may have a functional impact in unilateral stroke patients, especially in patients with ideomotor limb apraxia.

  15. Management of unilateral true vocal cord paralysis in children.

    2012-12-01

    Historically, information gained from the treatment of unilateral true vocal cord paralysis (UVCP) in adults was the same used to treat children. Today, there is a growing body of literature aimed specifically at the treatment of this condition in children. It is an area of growing interest as UVCP can significantly impact a child's quality of life. Children with UVCP may present with stridor, dysphonia, aspiration, feeding difficulties, or a combination of these symptoms. Diagnosis relies on laryngoscopy, but other adjuncts such as ultrasound and laryngeal electromyography may also be helpful in making the diagnosis and forming a treatment plan. In many instances, there is effective compensation by the contralateral vocal fold, making surgical intervention unnecessary. Children who cannot compensate for a unilateral defect may suffer from significant dysphonia that can affect their quality of life because their ability to be understood may be diminished. In these patients, treatment in the form of medialization or reinnervation of the affected recurrent laryngeal nerve may be warranted. UVCP is a well recognized problem in pediatric patients with disordered voice and feeding problems. Some patients will spontaneously recover their laryngeal function. For those who do not, a variety of reliable techniques are available for rehabilitative treatment. Improved diagnostics and a growing understanding of prognosis can help guide therapy decisions along with the goals and desires of the patient and his or her family.

  16. Primary continuous unilateral headaches: a nosologic model for hemicrania continua.

    2012-04-01

    Hemicrania continua was originally described as a strictly unilateral, continuous headache with an absolute response to indomethacin. Recognition of an increasing number of patients with the same clinical features except for a lack of response to indomethacin has generated controversy about whether the responsive/non-responsive phenotypes belong to the same disorder. We suggest that the non-responsive phenotype should be differentiated from the original concept of hemicrania continua, because it probably indicates a separate type of headache of undetermined nature, i.e. hemicrania incerta. However, differentiating hemicrania incerta from hemicrania continua does not imply that the two headaches are unrelated. Both hemicranias may outline a continuum, giving rise to a broader diagnostic field. There seems to be a syndrome of 'primary continuous unilateral headache' with at least two distinctive categories: hemicrania continua and hemicrania incerta, which are differentiated by their respective response to indomethacin. This division means plurality but adds precision, and allows a clear-cut diagnosis of some controversial cases.

  17. The Computerized Table Setting Test for Detecting Unilateral Neglect.

    Full Text Available Patients with unilateral neglect fail to respond normally to stimuli on the left side. To facilitate the evaluation of unilateral spatial neglect, we developed a new application that runs on a tablet device and investigated its feasibility in stroke patients.We made the computerized table setting test (CTST to run on the tablet computer. Forty acute ischemic stroke patients (20 patients with right hemispheric infarction with neglect, 10 patients with right hemispheric infarction without neglect, and 10 patients with left hemispheric infarction and 10 healthy controls were prospectively enrolled to validate the CTST. The test requires subjects to set a table by dragging 12 dishes located below the table on the tablet screen. The horizontal deviation of the 12 dishes from the midline of the table, the selection tendency measured by the sequence of the dish selection, and the elapsed time for table setting were calculated automatically.Parameters measured by the CTST were correlated with the results of conventional neglect tests. The horizontal deviation was significantly higher in patients with right hemispheric infarction with neglect compared with the other groups. The selection tendency and elapsed time also were significantly different in patients with right hemispheric infarction with neglect compared with the left hemispheric infarction and control groups, but were similar to those with right hemispheric infarction without neglect.The CTST is feasible to administer and comparable with conventional neglect tests. This new application may be useful for the initial diagnosis and follow-up of neglect patients.

    To systematically review the published clinical trials, case series, and case reports on left unilateral (LUL) electrode placement for clinical electroconvulsive therapy (ECT). PubMed, Ovid Medline, and the Cochrane Library were searched for articles concerning LUL ECT. Number of patients, efficacy, and cognitive outcomes were extracted from the papers that met our inclusion criteria. A total of 52 articles were included in this review, consisting of 33 clinical trials, seven case series, and 12 case reports. Overall, the efficacy of LUL electrode placement for the treatment of depression and psychosis is similar to that of right unilateral (RUL) and bilateral (BL) electrode placements. Patients receiving LUL ECT tend to experience more verbal memory impairment than patients receiving RUL ECT, but less verbal impairment than patients receiving BL ECT. In contrast, patients receiving LUL ECT tended to experience the least visual and nonverbal memory impairment, compared to patients receiving RUL or BL ECT. © 2017 John Wiley & Sons A/S.

    Full Text Available Introduction: To report the development of unilateral keratoconus in a healthy male after persistent unilateral eye rubbing by the nondominant hand which was not needed for professional activities. Methods: Observational case report. Results: A 60-year-old male was first seen in our clinic due to decreased vision in his left eye. Slit-lamp biomicroscopy of the left eye revealed Vogt’s striae, stromal thinning, and a stromal scar. Corneal topography showed a stage 4 keratoconus. Clinical examination and corneal topography of the right eye were normal. Medical history revealed a habit of chronic eye rubbing only in the left eye because of the right hand being occupied for professional needs. During follow-up of 5 years, Scheimpflug images of the right eye stayed normal while the left eye showed a stable cone. Discussion: This case report supports the hypothesis of mechanical fatigue of the cornea due to repetitive shear stress on the surface caused by eye-rubbing.

  20. Bending of a nonlinear beam reposing on an unilateral foundation

    Full Text Available This article is going to deal with bending of a nonlinear beam whose mathematical model was proposed by D. Y. Gao in (Gao, D. Y., Nonlinear elastic beam theory with application in contact problems and variational approaches,Mech. Research Communication, 23 (1 1996. The model is based on the Euler-Bernoulli hypothesis and under assumption of nonzero lateral stress component enables moderately large deflections but with small strains. This is here extended by the unilateralWinkler foundation. The attribution unilateral means that the foundation is not connected with the beam. For this problem we demonstrate a mathematical formulation resulting from its natural decomposition which leads to a saddle-point problem with a proper Lagrangian. Next we are concerned with methods of solution for our problem by means of the finite element method as the paper (Gao, D. Y., Nonlinear elastic beam theory with application in contact problems and variational approaches, Mech. Research Communication, 23 (1 1996 has no mention of it. The main alternatives are here the solution of a system of nonlinear nondifferentiable equations or finding of a saddle point through the use of the augmented Lagrangian method. This is illustrated by an example in the final part of the article.

    Full Text Available Introduction . Darier’s disease (dyskeratosis follicularis, keratosis follicularis, Darier-White disease, Darier disease is a rare genodermatosis inherited in autosomal dominant manner, caused by a mutation in the ATP2A2 gene located on chromosome 12. The gene encodes SERCA2 ATPase, an enzyme responsible for the metabolism of calcium ions in the endoplasmic reticulum. Darier’s disease is characterized by small brown hyperkeratotic papules which appear already in childhood or early adolescence. Skin lesions are located primarily in seborrhoeic areas. In addition to typical skin eruptions, the clinical picture may include involvement of the nails and mucous membranes. The histopathological pattern is characterized by the coexistence of two abnormalities: acantholysis and dyskeratosis. Objective . To present and discuss a case of unilateral Darier’s disease diagnosed and treated at our medical centre. Case report . We present the case of a 46-year old woman with Darier’s disease manifesting as skin lesions in the form of typical hyperkeratotic papules localized on the left part of the trunk and on left-side limbs. The diagnosis was made on the basis of clinical features and histopathological findings. A good therapeutic effect was achieved after introducing treatment with acitretin at a dose of 25 mg/day. Conclusions . The case presented is interesting because of the rarity of unilateral Darier’s disease.

  2. Acute Unilateral Vestibular Failure Does Not Cause Spatial Hemineglect.

    Julian Conrad

    Full Text Available Visuo-spatial neglect and vestibular disorders have common clinical findings and involve the same cortical areas. We questioned (1 whether visuo-spatial hemineglect is not only a disorder of spatial attention but may also reflect a disorder of higher cortical vestibular function and (2 whether a vestibular tone imbalance due to an acute peripheral dysfunction can also cause symptoms of neglect or extinction. Therefore, patients with an acute unilateral peripheral vestibular failure (VF were tested for symptoms of hemineglect.Twenty-eight patients with acute VF were assessed for signs of vestibular deficits and spatial neglect using clinical measures and various common standardized paper-pencil tests. Neglect severity was evaluated further with the Center of Cancellation method. Pathological neglect test scores were correlated with the degree of vestibular dysfunction determined by the subjective visual vertical and caloric testing.Three patients showed isolated pathological scores in one or the other neglect test, either ipsilesionally or contralesionally to the VF. None of the patients fulfilled the diagnostic criteria of spatial hemineglect or extinction.A vestibular tone imbalance due to unilateral failure of the vestibular endorgan does not cause spatial hemineglect, but evidence indicates it causes mild attentional deficits in both visual hemifields.

    Children with unilateral hearing loss (UHL) are being diagnosed at younger ages because of newborn hearing screening. Historically, they have been considered at risk for difficulties in listening and language development. Little information is available on contemporary cohorts of children identified in the early months of life. We examined auditory and language acquisition outcomes in a contemporary cohort of early-identified children with UHL and compared their outcomes at preschool age with peers with mild bilateral loss and with normal hearing. As part of the Mild and Unilateral Hearing Loss in Children Study, we collected auditory and spoken language outcomes on children with unilateral, bilateral hearing loss and with normal hearing over a four-year period. This report provides a cross-sectional analysis of results at age 48 months. A total of 120 children (38 unilateral and 31 bilateral mild, 51 normal hearing) were enrolled in the study from 2010 to 2015. Children started the study at varying ages between 12 and 36 months of age and were followed until age 36-48 months. The median age of identification of hearing loss was 3.4 months (IQR: 2.0, 5.5) for unilateral and 3.6 months (IQR: 2.7, 5.9) for the mild bilateral group. Families completed an intake form at enrolment to provide baseline child and family-related characteristics. Data on amplification fitting and use were collected via parent questionnaires at each annual assessment interval. This study involved a range of auditory development and language measures. For this report, we focus on the end of follow-up results from two auditory development questionnaires and three standardized speech-language assessments. Assessments included in this report were completed at a median age of 47.8 months (IQR: 38.8, 48.5). Using ANOVA, we examined auditory and language outcomes in children with UHL and compared their scores to children with mild bilateral hearing loss and those with normal hearing. On most

    2016-02-01

    Full Text Available Resumen Resumen Se realizó un trabajo de revisión de literatura de tipo narrativo, con el objetivo de explorar los modelos de intervención psicosocial en situaciones de desastre. Se incluyeron documentos rescatados a través de PubMed, SciELO, GoogleScholar, y Medline entre los años 1980-2014 en idioma español, inglés y francés. Además se efectuaron búsquedas en sitios web de organizaciones internacionales y gubernamentales para recopilar información relacionada a documentos que reportaban experiencias y resultados. Se identificaron 4 tipos de intervenciones psicosociales en situaciones de desastre: las basadas en el tiempo, las centradas en un tipo de desastre específico, las intervenciones por esferas o niveles de acción y las centradas en las personas. Los modelos de abordaje analizados contaron con diferencias y similitudes, a partir de la concepción teórica del desastre y de la visión integral del fenómeno. Se resalta la necesidad de generar y apoyar programas donde el empoderamiento y la participación comunitaria sean el eje de las intervenciones psicosociales.

    This study evaluates the effect of unilateral conductive hearing loss secondary to aural atresia on elementary school children's academic performance. Case control survey and review of audiometric data. One hundred thirty-two surveys were mailed to families of children with aural atresia, and 48 surveys were sent to families of children with unilateral sensorineural hearing loss (SNHL) to identify rates of grade retention, use of any resource, and behavioral problems. Audiometric data of the cohort were tabulated. Of the 40 atresia patients, none repeated a grade, but 65% needed some resources: 12.5% currently use a hearing aid, 32.5% use(d) a frequency-modulated system in school, 47.5% had an Individualized Education Plan, and 45% utilized speech therapy. Compared to the unilateral SNHL group and a cohort of children with unilateral SNHL in an earlier study, children with unilateral atresia were less likely to repeat a grade. Children in both unilateral atresia and SNHL groups were more likely to utilize some resource in the academic setting compared to the unilateral SNHL children in the prior study. Unilateral conductive hearing loss due to aural atresia has an impact on academic performance in children, although not as profound when compared to children with unilateral SNHL. The majority of these children with unilateral atresia utilize resources in the school setting. Parents, educators, and health care professionals should be aware of the impact of unilateral conductive hearing loss and offer appropriate habilitative services.

    Goldstein, L B

    1997-01-01

    The recovery of beam-walking ability following a unilateral sensorimotor cortex lesion in the rat is hypothesized to be noradrenergically-mediated. We carried out two experiments to further test this hypothesis. In the first experiment, bilateral 6-hydroxydopamine locus coeruleus (LC) lesions or sham LC lesions were made 2 weeks prior to a right sensorimotor cortex suction-ablation lesion or sham cortex lesion. In the second experiment, unilateral left or right LC lesions or sham LC lesions were made 2 weeks prior to a right sensorimotor cortex lesion or sham cortex lesion. Beam-walking recovery was measured over the 12 days following cortex lesioning in each experiment. Bilateral, unilateral left, and unilateral right LC lesions resulted in impaired recovery. These data provide additional support for the hypothesis that beam-walking recovery after sensorimotor cortex injury is, at least in part, noradrenergically mediated.

    Full Text Available Heterostructures of Si1-xGex alloys on Si (100 have been achieved using two different excimer laser techniques. The first one, the Laser Induced Chemical Vapour Deposition (LCVD, was used in order to deposit germanium on Si (100 substrates via photolysis of GeH4 as precursor gas. The resulting films show a very homogeneous and amorphous structure as determined by HREM, XRD and Raman analysis. These deposited amorphous germanium films and a part of their underlaying Si (100 substrate were melted using the second technique, the Pulsed Laser Induced Epitaxy (PLIE, inducing an epitactic recrystallization of a Si-Ge alloy. The analysis of the obtained alloys by HREM, XRD, and XPS, reveals a strong dependence of the crystal quality and of the germanium concentration profile from the number of pulses.

    El creciente interés que suscita la búsqueda de nuevas técnicas para la obtención de materiales semiconductores, compatibles con la tecnología del silicio, ha llevado a desarrollar un sistema de depósito y postprocesado en alto vacío (HV de Si-Ge mediante técnicas asistidas por láser excímero. Se han obtenido películas amorfas de germanio mediante el depósito químico en fase vapor inducido por láser (LCVD, que posteriormente han sido recristalizadas con uso de la inducción de epitaxia por medio de láser pulsado (PLIE. Las películas depositadas sobre substratos de silicio fueron caracterizadas mediante XRD, HREM y Raman, revelándose que son amorfas con un alto grado de homogeneidad. Se ha estudiado la morfología y la estequiometría de las muestras por medio de XRD, HREM y XPS tras el tratamiento para inducir la cristalinidad de la aleación sobre el substrato de silicio, observándose la dependencia del grado de heteroepitaxia y variación de la composición en la aleación, con el número y la energía de los pulsos del láser.

Los bajos niveles de eficiencia que muchos administradores de sistemasde distribución de agua (ASDA exhiben tienden a agudizar este problema. A través de herramientas de modelación asistida de sistemas de distribución de agua (MASDA, es posible generar un mayor conocimiento sobre la naturaleza y posibilidades de cada sistema. Como caso de estudio, CIVCO/ITCR, analizó la situación del sistema de distribución de agua potable del campo/escuela Scout de Costa Rica. Al identificarse deficiencias irremediables, se decidió diseñar un nuevo sistema que pueda afrontar adecuadamente una ocupación máxima de 280 personas durante un evento crítico de 8 días. Una vez definidos los patrones de diseño, se evalúan diversos escenarios de modelación a través de EPANet 2.0. La información arrojadaindica que los supuestos originales de diseño son adecuados y el sistema presenta condiciones estables de flujo uniforme durante todo el período de modelación. Por otro lado, la concentración de cloro residual en el sistema llega a estabilizarse después de pasado del período de ocupación máxima. El proyecto MASDA seguirá prestando en el futuro asesoramiento y apoyo tecnológico a los administradores de sistemas de distribución de agua, y les permitirá servir de una forma eficiente, constante y confiable a las comunidades bajo su administración, al tiempo que se reduce el impacto sobre las fuentes de producción.

    In approximately half of cases of primary aldosteronism (PA), the cause is a surgically-resectable unilateral aldosterone-producing adrenal adenoma. However, long-term data on surgical outcomes are sparse. We report on clinical outcomes post-adrenalectomy in a cohort of patients with PA who underwent surgery. Retrospective review of patients treated for PA in a single UK tertiary centre. Of 120 consecutive patients investigated for PA, 52 (30 male, median age 54, range 30-74) underwent unilateral complete adrenalectomy. Blood pressure, number of antihypertensive medications, and serum potassium were recorded before adrenalectomy, and after a median follow-up period of 50 months (range 7-115). Recumbent renin and aldosterone were measured, in the absence of interfering antihypertensive medication, ≥3months after surgery, to determine if PA had been biochemically cured. Overall, blood pressure improved from a median (range) 160/95 mmHg (120/80-250/150) pre-operatively to 130/80 mmHg (110/70-160/93), P < 0.0001. 24/52 patients (46.2%) had cured hypertension, with a normal blood pressure post-operatively on no medication. 26/52 (50%) had improved hypertension. 2/52 patients (3.8%) showed no improvement in blood pressure post-operatively. Median (range) serum potassium level increased from 3.2 (2.3-4.7) mmol/l pre-operatively to 4.4 mmol/l (3.3-5.3) post-operatively, P < 0.0001). Median (range) number of antihypertensive medications used fell from 3 (0-6) pre- to 1 post-operatively (range 0-4), P < 0.0001. Unilateral adrenalectomy provides excellent long-term improvements in blood pressure control, polypharmacy and hypokalaemia in patients with lateralizing PA. These data may help inform discussions with patients contemplating surgery. © The Author 2016. Published by Oxford University Press on behalf of the Association of Physicians. All rights reserved.

    Unilateral pulmonary artery hypoplasia or agenesis without congenital cardiovascular anomalies is rare in adults. We report a case of a 36-year-old man with isolated left unilateral pulmonary artery hypoplasia with recurrent hemoptysis. On computed tomography (CT), the left pulmonary artery showed hypoplasia with multiple collateral vessels seen in the mediastinum and the left hemithorax. Also, parenchymal bands and peripheral linear opacities were seen in the affected lung, which were probably due to chronic infarction induced by unilateral pulmonary artery hypoplasia. There are only a few reports focusing on the radiologic findings in the pulmonary parenchyma induced by unilateral pulmonary artery hypoplasia, such as parenchymal bands and peripheral linear opacities. Therefore we report this case, which focused on the CT findings in the pulmonary parenchyma due to isolated unilateral pulmonary artery hypoplasia.

    Contextual fear memory depends on the hippocampus, but the role of unilateral hippocampus in this type of memory remains unclear. Herein, pharmacological inactivation or excitotoxic lesions were used to study the role of unilateral hippocampus in the stages of contextual fear memory. The pharmacological experiments revealed that compared with the control groups, unilateral hippocampal blockade did not impair 1-day recent memory following learning, whereas bilateral hippocampal blockade significantly impaired this memory. The lesion experiments showed that compared with the control groups, the formed contextual fear memory was retained for 7 days and that 30-day remote memory was markedly reduced in unilateral hippocampal lesion groups. These results indicate that an intact bilateral hippocampus is required for the formation of remote memory and that unilateral hippocampus is sufficient for recent contextual fear memory.

    Noonan syndrome (NS) is an etiologically heterogeneous disorder caused by mutations in the RAS-MAPK signaling pathway. Noonan-Like/Multiple Giant Cell Lesion (NL/MGCL) syndrome is initially described as the occurrence of multiple gnathic giant cell lesions in patients with phenotypic features of NS. Nowadays, NS/MGCL syndrome is considered a variant of the NS spectrum rather than a distinct entity. We report the case of a 14-year-old female patient carrying a SOS1 mutation with a unilateral giant cell lesion of the right mandible. Cross-sectional imaging such as CT and MRI are not specific for the diagnosis of oral giant cell lesions. Nonetheless, intralesional scattered foci of low SI on T2-WI, corresponding to hemosiderin deposits due to hemorrhage, can help the radiologist in narrowing down the differential diagnosis of gnathic lesions in patients with NS.

    The mathematical analysis of contact problems, with or without friction, is an area where progress depends heavily on the integration of pure and applied mathematics. This book presents the state of the art in the mathematical analysis of unilateral contact problems with friction, along with a major part of the analysis of dynamic contact problems without friction. Much of this monograph emerged from the authors'' research activities over the past 10 years and deals with an approach proven fruitful in many situations. Starting from thin estimates of possible solutions, this approach is based on an approximation of the problem and the proof of a moderate partial regularity of the solution to the approximate problem. This in turn makes use of the shift (or translation) technique - an important yet often overlooked tool for contact problems and other nonlinear problems with limited regularity. The authors pay careful attention to quantification and precise results to get optimal bounds in sufficient conditions f...

    The interaction of a two-dimensional supersonic jet with a unilateral barrier parallel to the flow symmetry plane was studied to account for effects due to gas viscosity and backgound-gas ejection from the region into which the jet expands. In the present experiments, the incident shock wave was reflected at the end of a shock tube equipped with a nozzle. The jet emerged into a pressure chamber 6 cu m in volume and the environmental pressure ratio of the flow in the quasi-stationary phase remained constant. The light source was an OGM-20 laser operating in the giant-pulse mode. Due to background-gas ejection, the gas density in the vicinity of the barrier is much less than on the unconfined side of the jet. The resulting flow is characterized by two distinct environmental pressure ratios: the flow is underexpanded near the barrier, while on the other side it is overexpanded.

    Full Text Available The musculocutaneous nerve usually branches out from the lateral cord of brachial plexus. It innervates the corcobrachialis, biceps brachii and brachialis muscles and continues as the lateral cutaneous nerve of forearm without exhibiting any communication with the median nerve or any other nerve. We report unilateral variation in motor innervations of the left arm in a 58-year-old male cadaver. The musculocutaneous nerve was found to be absent. A muscular branch of the median nerve was supplying the coracobrachialis muscle. In the middle of arm, the median nerve was found to be branching out, bifurcating and supplying the long and short head of biceps. The median nerve was found to be giving a separate branch, which supplied the brachialis muscle and continued as the lateral cutaneous nerve of forearm. The right sided structures were found to be normal. Surgeons should keep such variations in mind while performing arm surgeries.

    OBJECTIVE: To determine the age of menopause after premenopausal unilateral oophorectomy (UO) and to establish whether UO at a young age leads to menopause at a younger age than if UO occurs at an older age. METHODS: A cohort of 28 731 women, of whom 17 781 (62%) were menopausal, was investigated....... Information on menopause was obtained from self-reported questionnaires. Surgical data were obtained from the National Patient Register to avoid recollection bias. Age of menopause after UO/not UO was determined using Kaplan-Meier curves. Cox regression was used to identify factors of importance for early...... menopause. RESULTS: UO was performed in 1148 women. Women with UO after the age of 45 years, premenopausal hysterectomy, bilateral oophorectomy and cancer were excluded, leaving 236 in the analysis. Menopause occurred 1.8 years earlier after UO compared to women with two intact ovaries (mean 49.5 vs. 51...

    Abstract Disorders of sex development (DSD) present in different forms but, in most cases, with visible anomalies of the external genitalia. The diagnosis of DSD can have a vast impact on an individual; in addition to concerns about fertility and a higher risk of neoplasia, it may have severe...... psychosocial impact on the patient. This report presents two apparently healthy cases referred for operation because of unilateral undescended testis. In these two patients, uterine remnants were found during the operation, and underlying DSD conditions were unexpectedly diagnosed. One patient had a 45,X/46,XY...... mosaic karyotype, while the second patient had persistent müllerian duct syndrome, probably due to an anti-müllerian hormone receptor defect. Both conditions are extremely rare, but the findings reinforce that DSD should be considered in patients with cryptorchidism, especially if other clinical signs...

    2007-01-01

    In order to evaluate the role of botulinum toxin induced ptosis as an occlusion method to treat unilateral deep strabismic amblyopia in two uncooperative children, we injected 0.2 ml of diluted botulinum toxin in the levator palpaebrae; low sedation was necessary in one of the two children. In both cases a marked ptosis was achieved, which lasted about four weeks and then gradually resolved completely. The visual acuity of the ablyopic eye increased in both children, making patching easy thereafter. One child developed amblyopia in the injected eye, which was handled successfully using part-time occlusion. No other side effects were noted. Whether this new method could be a simple, safe and effective alternative method of occlusion for the treatment of deep amblyopia in uncooperative children needs to be proven with a larger series of children.

    Full Text Available Optic neuritis (ON is one of the most common manifestations of central nervous system involvement caused by various etiologies. Lyme ON is an exceedingly rare ocular manifestation of Lyme disease (LD and only a few cases have been published in the literature. Lyme ON is very rare but should be included in the differential diagnosis in unexplained cases, particularly in Lyme endemic areas. Careful and detailed examination and investigation are warranted to make the diagnosis. We report this case to increase awareness of clinicians to include Lyme disease in differential diagnosis of ON for unexplained cases of ON. Herein we present a unique case with a unilateral ON caused by LD along with pre- and posttreatment findings and literature review.

    Pachydermodactyly is a rare digital fibromatosis characterized by asymptomatic fusiform soft-tissue swellings of the proximal interphalangeal joints of the hands. It usually affects healthy adolescent males with a negative family history. As a rule, clinical presentation of the disease is bilateral and symmetrical enlargement of the joints. So it can be misdiagnosed with inflammatory rheumatic diseases, especially with juvenile chronic arthritis. A prompt clinical diagnosis of the disease would prevent inappropriate treatment with immunosuppressive agents or steroids and unnecessary expensive diagnostic procedures such as biopsy or magnetic resonance imaging. Once diagnosed, patients should be advised in order to avoid repetitive traumas of the hands, rubbing and cracking of the fingers, obsessive-compulsive use of computer and video games. The joint outcome is always benign. Here, we report a case of pachydermodactyly differs from the typical clinical picture of pachydermodactyly in the unilateral distribution of the lesions.

    To evaluate the sciatic nerves of patients with unilateral sciatica by using an ultrasound, and to determine whether ultrasonographic findings were related to clinical and electrophysiologic parameters. Cross-sectional study. Physical medicine and rehabilitation departments of a university hospital and a rehabilitation hospital. Consecutive patients (N=30; 10 men, 20 women) with complaints of low back pain and unilateral sciatica of more than 1 month of duration were enrolled. Not applicable. All patients underwent a substantial clinical assessment, and they were also evaluated by electromyogram and magnetic resonance imaging. Pain was evaluated by a visual analog scale and the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Scale. A linear array probe (7.5-12MHz) was used to scan sciatic nerves bilaterally in the prone position. Sciatic nerve diameters-thickness (short axis) and width (long axis)-and cross-sectional areas were measured bilaterally at the same levels, proximal to the bifurcation and midthigh. The values pertaining to the unaffected limbs were taken as controls. When compared with the unaffected sides, mean values for sciatic nerve measurements-long axis at bifurcation level (P=.017) and cross-sectional area at midthigh level (P=.005)-were significantly larger on the affected sides. Swelling ratios negatively correlated with symptom duration (r=-.394, P=.038) and LANSS scores (r=-.451, P=.016) at only midthigh level. Sciatic nerves seem to be enlarged on the side of sciatica in patients with low back pain. Our preliminary results may provide insight into better understanding the lower limb radiating pain in this group of patients. Copyright © 2012 American Congress of Rehabilitation Medicine.

    Analysis of 1216 abdominal aortographies and selective renovasographies undertaken at the Institute of Radiology, Clinical Hospital Centre Rijeka during the period 1979-1985, was performed. 39 (3,2%) unilateral renal agenesias were established, a percentage that is significantly higher than reported by other authors. Analysis of all angiographic parameters of a single kidney was also worked out. A significanlty high percentage (66,7%) of hypertension was diagnosed in this group. Congenital renal failures make their appearance in the early embryological development and are discovered, if compatible with life, most frequently at an advanced age. Statistical data on the frequency during a lifetime are less reliable because a great number of anomalies are never discovered during a person's life. The etiology of variations and congenital failure of renal arteries is unknown in 90% of the cases, and most of the malformations are without characteristic symptomatology. Since the anatomic relations in anomalous kidney are disturbed, the sign of the disease can develop atypical forms causing frequent errors in diagnosis. The kidney is supplied by numerous lateral branches of the medial sacral artery, i.e. the aorta, during embryological development. Later, some of them degenerate or mutually connect themselves, and the definitive kidney has been usually penetrated by only one artery and one vein on the same side (1). If this is not so, i.e. when the obliterations of caudal metanephogenic arteries are only partially present, then the renal arteries emerge from the iliac or lumbar arteries (2,3). Bilateral renal agenesia is extreme and incompatible with life, and hence of small clinical importance. Unilateral agenesia makes its appearance according to various statistics and authors from the obductional materials in ratio 1:1000 (4,5), clinical ones 1:5000 (6, 7, 8) and the angiographically 1:76(9), more exactly 1:35 cases (10).

    the long-term outcomes of wartime transtibial amputations have not been well documented. The purpose of this case series is to present the long-term functional, social, and psychological outcomes of modern-day military unilateral transtibial amputees. the Iranian Veterans Administration of the Khorasan province invited their Iranian military amputees from the Iran-Iraq War (1980-1988) to its medical center for evaluation. The patients filled out a detailed questionnaire and were interviewed and examined by each team member. two hundred (77%) of the 260 invited amputees were willing and able to come back for follow-up. Ninety-six of these patients (48%) were unilateral transtibial amputation. The average follow-up was 17.4 years (range 15-22 years). Land mines were the leading cause of war injury necessitating a transtibial amputation (68%). The most common symptoms about their amputated limbs were phantom sensations (54%), phantom pain (17%), and stump pain (42%). Lower back pain, contralateral (nonamputated limb) knee pain, and ipsilateral (amputated limb) knee pain were reported by 44%, 38%, and 13% of subjects, respectively. Sixty-five percent of patients were employed or had been employed for multiple years after their war injury. All patients were married, and 97% had children. Fifty-four percent of amputees reported psychological problems; 26% were currently utilizing psychological support services. at long-term follow-up, most military transtibial amputees experienced phantom sensation or some type of stump pain. More than half had persistent psychiatric problems, but only about half of these patients were receiving psychological treatment. Although this case series reports the status of these amputees, the next step would be to prospectively follow modern wartime amputees using standardized, validated outcome measures. With the goal of optimizing long-term amputee outcomes, researchers should correlate outcomes with demographics, injury characteristics, and

    Correct subtyping of primary aldosteronism (PA) is essential for good surgical outcomes. Adrenal vein sampling (AVS) and/or computed tomography (CT) are used for PA subclassification. Clinical and/or biochemical improvement after surgery, however, is not always achieved in patients with presumed unilateral PA. We aimed to identify the pitfalls in PA subclassification leading to surgical treatment failures. We retrospectively studied 208 patients who underwent adrenal vein sampling (AVS) for PA subclassification in a tertiary referral centre, between January 2009 and August 2016. Simultaneous bilateral AVS was performed before and after cosyntropin administration. We implemented immunohistochemistry for aldosterone synthase (CYP11B2) and 17α-hydroxylase/17,20 lyase (CYP17A1) in adrenal glands resected from patients without improvement of PA after surgical treatment and from those with limitations in AVS interpretation. Of 55 patients who underwent adrenalectomy, three (5.5%) had no improvement of PA. All three patients underwent partial adrenalectomy to remove a CT-detected nodule present on the same side with AVS lateralization. Immunohistochemistry revealed a CYP11B2-negative nodule in both cases available. All patients who underwent total adrenalectomy based on AVS lateralization benefitted from surgery, including three patients with unilateral unsuccessful AVS and aldosterone suppression in the catheterized side vs inferior vena cava. Radiographically identified adrenal nodules are not always a source of PA, even when ipsilateral with AVS lateralization. These data caution against reliance on imaging findings, either alone or in conjunction with AVS, to guide surgery for PA. © 2017 John Wiley & Sons Ltd.

    benignas del hígado tratadas quirúrgicamente mediante el abordaje transvaginal asistido por minilaparoscopia. Pacientes y métodos: mujeres de 44 y 45 años de edad, respectivamente. La paciente 1 presentaba un pequeño tumor de 1,2 cm de Ø, en el lóbulo izquierdo del hígado. En su preoperatorio no se logró precisar su etiología y se decidió extirparlo quirúrgicamente. La paciente 2 presentaba un quiste simple del hígado muy sintomático de 8 cm de Ø situado en el subsegmento VI, se negó a realizarse el tratamiento esclerosante por vía percutánea, por lo que se recomendó el tratamiento quirúrgico. Se les ofreció a ambas realizar la intervención mediante cirugía laparoscópica o el abordaje transvaginal, aceptando este último. El neumoperitoneo se realizó con presión de 15 mmHg. Se colocaron 2 minipuertos en abdomen, uno en región umbilical de 5 mm Ø y el otro de 3 mm Ø en el sitio más próximo a la lesión. Con visión directa se colocó 1 trocar en la pared posterior del fondo del saco vaginal de 11 mm Ø para el paso de un endoscopio rígido. En la paciente 1 se utilizó este mismo orificio para, adyacente al trocar, introducir un disector largo. En la paciente 2 se introdujo un segundo trocar de 5 mm Ø para el paso de instrumentos de trabajo. Ambos especímenes fueron extraídos a través de la vagina en bolsas extractoras. Se registró el tiempo quirúrgico, necesidad de analgésicos y complicaciones postoperatorias. Resultados: los tiempos quirúrgicos fueron de 51 y 73 minutos, respectivamente. La paciente operada del quiste hepático requirió administración de analgésico postoperatorio. El alta hospitalaria fue dada antes de las 24 horas de la intervención. No se han presentado complicaciones postoperatorias relacionadas con el proceder después de un seguimiento mínimo de 6 meses. Conclusiones: con el empleo de instrumentos rígidos, fue posible realizar el tratamiento quirúrgico de dos lesiones benignas del hígado, de poca

    Unilateral and bilateral subthalamic nucleus deep brain stimulation (STN DBS) in Parkinson's disease (PD) result in weight gain in the initial postoperative months, but little is known about the changes in weight following unilateral and staged bilateral STN DBS over longer time intervals. A case-control comparison evaluated weight changes over 2 years in 43 consecutive unilateral STN DBS patients, among whom 25 elected to undergo staged bilateral STN DBS, and 21 age-matched and disease severity matched PD controls without DBS. Regression analyses incorporating age, gender, and baseline weight in case or control were conducted to assess weight changes 2 years after the initial unilateral surgery. Unilateral STN DBS and staged bilateral STN DBS patients gained 3.9 ± 2.0 kg and 5.6 ± 2.1 kg versus their preoperative baseline weight (P < 0.001, respectively) while PD controls without DBS lost 0.8 ± 1.1 kg. Although bilateral STN DBS patients gained 1.7 kg more than unilateral STN DBS patients at 2 years, this difference was not statistically significant (P = 0.885). Although there was a trend toward greater weight gain in staged bilateral STN DBS patients versus unilateral patients, we found no evidence for an equivalent or synergistic increase in body weight following placement of the second DBS electrode.

  3. Analysis of visual outcomes and complications following levator resection for unilateral congenital blepharoptosis without strabismus

    2013-08-01

    Full Text Available Background: It is challenging to manage congenital blepharoptosis, especially unilateral, because symmetry is difficult to achieve under general anesthesia and age at which the ptosis should be corrected is still controversial. The aim of our study is to analyze visual and surgical outcomes after levator resection for unilateral congenital blepharoptosis. Methods: Charts of patients with unilateral congenital blepharoptosis who underwent levator resection at the Chang Gung Memorial Hospital from 1991 through 2000 were reviewed. The resultant database was interrogated for demographic data, severity, surgical timing, visual outcomes, surgical outcomes, and complications. Results: Eighty-four children underwent levator resection for unilateral congenital blepharoptosis: 16.7% of these patients had amblyopia and 84.5% had surgical success following levator resection. Severe ptosis (p = 0.0288, p < 0.05 and surgery at less than 2 years of age (p = 0.0126, p < 0.05 were the important factors contributing to surgical failure. Age at surgery (p = 0.0058, p < 0.01 and amblyogenic ametropia (p = 0.0001, p < 0.001 were found to be significantly associated with the postoperative visual results. Conclusion: The levator resection provides satisfactory results both in function and cosmesis in patients with unilateral congenital blepharoptosis. Amblyogenic ametropia is the leading cause of amblyopia in the patients with unilateral isolated congenital blepharoptosis. However, patients with unilateral congenital blepharoptosis should have cycloplegic refraction as early as possible, and their visual status monitored until visual maturity.

  4. The effect of unilateral ovariectomy on early embryonic survival and embryo development in rabbits

    Full Text Available Unilateral ovariectomy can be used to study uterine capacity in rabbits because an overcrowding of the functional uterine horn is produced. Due to the uterus duplex, the rabbit is the ideal model for such studies. However, this technique may affect embryo survival. The aim of this work is to study the effect of unilateral ovariectomy on early embryo survival and development in rabbit. A total of 101 unilateral ovariectomised females and 52 intact females were compared after slaughter at 30 h post-mating. Early embryo survival was estimated as the ratio between number of embryo recovered and ovulation rate. No differences were found between intact and unilaterally ovariectomised females in this trait. Unilateral ovariectomy did not change embryo development, measured as the number of embryo cells. Variability of embryo development was not affected either. At 30 h post-mating, the majority of embryos (86.2% were 4-cell stage. Embryo quality was evaluated according to morphological criteria. No difference in embryo quality between intact and unilaterally ovariectomised females was found. Therefore, unilateral ovariectomy performed before puberty in rabbit does not modify early embryo survival and development.

    Full Text Available Background: Posterior polymorphous corneal dystrophy (PPCD is typically considered bilateral and asymptomatic. However, few case reports on patients with unilateral PPCD with asymmetric refractive error have mentioned anisometropic amblyopia development. In support of this, we report 3 cases of unilateral PPCD that presented as anisometropic astigmatism. Visual prognosis related to amblyopia development is discussed. Case Presentation: All 3 patients had a band lesion in the affected eye and a difference of at least 1.5 diopters in cylindrical refractive error between their eyes. The affected eye had a greater amount of astigmatism in all cases. Two patients (Cases 1 and 2 also had amblyopia in the affected eye. Case 1 was a 25-year-old male with a unilateral PPCD diagnosis and a band lesion involving the visual axis. Case 2 was an 11-year-old boy diagnosed with unilateral PPCD. The boy was treated with occlusion and atropine therapy over a 2-year period. Case 3 was a 4-year-old girl diagnosed with unilateral PPCD. The girl had a 30-month history of corrective spectacle use and had no amblyopia. In all cases, the corneal endothelial cell count was lower in the affected eye than in the unaffected contralateral eye. Conclusions: Practitioners should closely monitor patients with unilateral PPCD for astigmatic anisometropia and amblyopia development. Visual prognosis for patients with unilateral PPCD may be related to lesion position, age at diagnosis, astigmatism severity, and early-childhood corrective spectacle use.

    2002-01-01

    Introduction: Relative renal function (RRF) is used as an important parameter in the surgical decision of hydronephrosis. In addition, the presence of a supranormal RRF (RRF > 55%) in the hydronephrotic kidney had been recognized. However, this over estimation is, in our experience, not only present with a RRF over 55%. We evaluated demographic data, ultrasonographic finding, age of surgery, presentation (antenatal diagnosis vs postnatal clinical symptoms) in children with unilateral hydronephrosis and a RRF which decreased after surgery. Materials and Methods: Of a series of 66 patients with unilateral ureteropyelic junction obstruction (UPJ) obstruction consecutively operated and followed in the Pediatric Urology unit of Catholic University of Chile, we analyzed 8 cases (12%) in which the relative renal function quantified by diuretic renography with Tc99 MAG3 decreased during follow-up after surgery, over 10% of the baseline value; 6 to 12 months post pyeloplasty, 7 boys, 6 cases with UPJ obstruction of the left side. 3 cases were diagnosed by prenatal ultrasound, 1 by abdominal mass, 1 by urinary tract infection, 1 by abdominal pain and 2 by screening. The age at the time of the surgery was in 4 cases 1 month of life, in two children between 6 and 12 months of age, one boy was 2.4 year old and another one was 7.3 year old. All were considered as a severe hydronefrosis in the ultrasound and 4 cases had a severe atrophy of renal parenchyma. The initial RRF of these cases varied from 35% to 62%. In half of the cases the initial RRF was considered normal, in 2 cases was abnormal ( 55%). In all of these children the RRF decreased after surgery in an average of 35% (28%-54%) of the initial RRF, none of these patients had a normal RRF after surgery. There was no differences in clinical presentation and radiological findings among them. However, it is worth to mention that the symptomatic presentation (pain, abdominal mass) was more frequent in this group that in our

    Full Text Available Objectives: To evaluate the surgical treatments and results of the patients with superior oblique muscle palsy (SOMP. Materials and Methods: Clinical charts of the patients with unilateral SOMP who were operated in our clinic between 1999 and 2009 were evaluated retrospectively. Patients’ demographics, preoperative signs, surgical procedure, complications, and final results were recorded. Results: Thirty-seven patients were included in the study, [21 (59% male, 15 (41% female]. The mean age was 20.6 years at the time of operation. The mean time interval between diagnosis and operation was 7.3 years. Postoperative follow-up period was 2.04 (ranging 1-10 years. Diplopia was determined in seven (18.9% patients, and abnormal head position in 36 (97.3% patients. Only inferior oblique tenotomy with distal muscle resection was performed in 25 patients. In addition, five patients had recession of the contralateral inferior rectus muscle and two patients had recession of the ipsilateral superior rectus muscle additional to inferior oblique tenotomy. Abnormal head position was completely improved in all of the patients postoperatively. The preoperative average score of the inferior oblique muscle (IOM overaction was +3.3±0.8, and postoperative overaction was found in only two patients (+1.5. There was statistically significant difference between the two periods (p<0.001. The average score of the superior oblique muscle hypofunction was -2.18 preoperatively, and in only three patients, the score was found -1.0 postoperatively. Difference between the two periods was statistically significant (p<0.001. While the preoperative average vertical deviation was 22 PD in primary position, none of the patients had hyperdeviation postoperatively. Diplopia was resolved in all seven affected patients postoperatively. Contralateral IOM hyperfunction was the most common complication (13.5%. Adherence syndrome was seen in none of the patients. Conclusion: It was found

    Full Text Available ObjectiveNearly two-thirds of patients with vestibular schwannoma (VS are reporting a significantly impaired quality of life due to tinnitus. VS-associated tinnitus is attributed to an anatomical and physiological damage of the hearing nerve by displacing growth of the tumor. In contrast, the current pathophysiological concept of non-VS tinnitus hypothesizes a maladaptive neuroplasticity of the central nervous system to a (hidden hearing impairment resulting in a subjective misperception. However, it is unclear whether this concept fits to VS-associated tinnitus. This study aims to determine the clinical predictors of VS-associated tinnitus to ascertain the compatibility of both pathophysiological concepts.MethodsThis retrospective study includes a group of 478 neurosurgical patients with unilateral sporadic VS evaluated preoperatively regarding the occurrence of ipsilateral tinnitus depending on different clinical factors, i.e., age, gender, tumor side, tumor size (T1–T4 according to the Hannover classification, and hearing impairment (Gardner–Robertson classification, GR1–5, using a binary logistic regression.Results61.8% of patients complain about a preoperative tinnitus. The binary logistic regression analysis identified male gender [OR 1.90 (1.25–2.75; p = 0.002] and hearing impairment GR3 [OR 1.90 (1.08–3.35; p = 0.026] and GR4 [OR 8.21 (2.29–29.50; p = 0.001] as positive predictors. In contrast, patients with large T4 tumors [OR 0.33 (0.13–0.86; p = 0.024] and complete hearing loss GR5 [OR 0.36 (0.15–0.84; p = 0.017] were less likely to develop a tinnitus. Yet, 60% of the patients with good clinical hearing (GR1 and 25% of patients with complete hearing loss (GR5 suffered from tinnitus.ConclusionThese data are good accordance with literature about non-VS tinnitus indicating hearing impairment as main risk factor. In contrast, complete hearing loss appears a negative predictor for tinnitus. For the first

    Contusion-type injuries to the spinal cord are characterized by tissue loss and disruption of spinal pathways. Midcervical spinal cord injuries impair the function of respiratory muscles and may contribute to significant respiratory complications. This study systematically assessed the impact of a 100-kDy unilateral C4 contusion injury on diaphragm muscle activity across a range of motor behaviors in rats. Chronic diaphragm electromyography (EMG) was recorded before injury and at 1 and 7 days postinjury (DPI). Histological analyses assessed the extent of perineuronal net formation, white-matter sparing, and phrenic motoneuron loss. At 7 DPI, ∼45% of phrenic motoneurons were lost ipsilaterally. Relative diaphragm root mean square (RMS) EMG activity increased bilaterally across a range of motor behaviors by 7 DPI. The increase in diaphragm RMS EMG activity was associated with an increase in neural drive (RMS value at 75 ms after the onset of diaphragm activity) and was more pronounced during higher force, nonventilatory motor behaviors. Animals in the contusion group displayed a transient decrease in respiratory rate and an increase in burst duration at 1 DPI. By 7 days, following midcervical contusion, there was significant perineuronal net formation and white-matter loss that spanned 1 mm around the injury epicenter. Taken together, these findings are consistent with increased recruitment of remaining motor units, including more fatigable, high-threshold motor units, during higher force, nonventilatory behaviors. Changes in diaphragm EMG activity following midcervical contusion injury reflect complex adaptations in neuromotor control that may increase the risk of motor-unit fatigue and compromise the ability to sustain higher force diaphragm efforts. NEW & NOTEWORTHY The present study shows that unilateral contusion injury at C4 results in substantial loss of phrenic motoneurons but increased diaphragm muscle activity across a range of ventilatory and higher

    OBJECTIVE. We determined whether listening to excerpts of classical music ameliorates unilateral neglect (UN) in stroke patients. METHOD. In this within-subject study, we recruited and separately tested 16 UN patients with a right-hemisphere stroke under three conditions within 1 wk. In each condition, participants were asked to complete three subtests of the Behavioral Inattention Test while listening to classical music, white noise, or nothing. All conditions and the presentation of the tests were counterbalanced across participants. Visual analog scales were used to provide self-reported ratings of arousal and mood. RESULTS. Participants generally had the highest scores under the classical music condition and the lowest scores under the silence condition. In addition, most participants rated their arousal as highest after listening to classical music. CONCLUSION. Listening to classical music may improve visual attention in stroke patients with UN. Future research with larger study populations is necessary to validate these findings. Copyright © 2013 by the American Occupational Therapy Association, Inc.

    Full Text Available Proptosis, the forward protrusion of the eyeball, is a common manifestation of a wide variety of diseases inside the orbit and its spaces. Its diagnosis is usually a combined effort of the ophthalmologist, otolaryngologist, neurosurgeon, and radiologist. A clinical study of twenty-five cases with unilateral proptosis were studied in different age groups over a period of about 3 years under different headings like distribution, clinical features, radiological features, histopathological aspects, management, and outcomes of diseases. Proptosis measurement was done by simple/plastic ruler exophthalmometry, and diagnosis was made after a detailed clinical examination and ancillary tests. Treatment modality was decided based on radiological and histopathological examination reports, which included medical surgery, radiotherapy, and chemotherapy or a combination of all. In our study, most of the patients were in the age group of more than 60 years. The M : F ratio is 3 : 1. One case had a large proptosis of 18 mm above normal and 2 cases were as small as 3 mm. Diagnosis was mainly done by clinical features and confirmed by radiological and histopathological features. Most of them were treated medically (13 cases, i.e., 52% and the rest by surgery with a combination of radiotherapy/chemotherapy (12 cases, i.e., 48%.

    To provide morphological descriptions of microphthalmia or anophthalmia in eight pythons using microcomputerized tomography (μCT), magnetic resonance imaging (MRI), and histopathology. Seven Burmese pythons (Python bivittatus) and one ball python (P. regius) with clinically normal right eyes and an abnormal or missing left eye. At the time of euthanasia, four of the eight snakes underwent necropsy. Hereafter, the heads of two Burmese pythons and one ball python were examined using μCT, and another Burmese python was subjected to MRI. Following these procedures, the heads of these four pythons along with the heads of an additional three Burmese pythons were prepared for histology. All eight snakes had left ocular openings seen as dermal invaginations between 0.2 and 2.0 mm in diameter. They also had varying degrees of malformations of the orbital bones and a limited presence of nervous, glandular, and muscle tissue in the posterior orbit. Two individuals had small but identifiable eyes. Furthermore, remnants of the pigmented embryonic framework of the hyaloid vessels were found in the anophthalmic snakes. Necropsies revealed no other macroscopic anomalies. Eight pythons with unilateral left-sided microphthalmia or anophthalmia had one normal eye and a left orbit with malformed or incompletely developed ocular structures along with remnants of fetal structures. These cases lend further information to a condition that is often seen in snakes, but infrequently described. © 2014 American College of Veterinary Ophthalmologists.

    For the past 5 years, a 56-year-old patient has been displaying monocular progressive pigmentary changes in the left eye. Heterochromy of the left eye has been known since childhood. The other eye is clinically and functionally normal. The patient was adopted and he has no children. Therefore, we have no family history. The patient was examined clinically and by means of electroretinography, electrooculography, perimetry, computer tomography, pulsatile ocular blood flow (POBF) measurement, serology and Doppler sonography. Electrophysiology displayed a considerable reduction of scotopic and photopic ERGs, a reduced dark-through, and a reduced light-rise in the left eye, whereas the fellow eye was normal. The visual field was limited to 5 deg around the fixation point, and a peripheral crescent-shaped arch encircled the temporal-inferior quadrant concomitant to the pigmentary changes. By computer tomography and Doppler sonography a vascular affection was excluded. The left eye displayed lower POBF values. All serological tests were found negative. The clinical picture and negative exclusion criteria indicate a unilateral retinitis pigmentosa. However, with regard to the literature an unequivocal diagnosis can only be made upon hereditary evidence.

  17. Changes in contralateral protein metabolism following unilateral sciatic nerve section

    Changes in nerve biochemistry, anatomy, and function following injuries to the contralateral nerve have been repeatedly reported, though their significance is unknown. The most likely mechanisms for their development are either substances carried by axoplasmic flow or electrically transmitted signals. This study analyzes which mechanism underlies the development of a contralateral change in protein metabolism. The incorporation of labelled amino acids (AA) into proteins of both sciatic nerves was assessed by liquid scintillation after an unilateral section. AA were offered locally for 30 min to the distal stump of the sectioned nerves and at homologous levels of the intact contralateral nerves. At various times, from 1 to 24 h, both sciatic nerves were removed and the proteins extracted with trichloroacetic acid (TCA). An increase in incorporation was found in both nerves 14-24 h after section. No difference existed between sectioned and intact nerves, which is consistent with the contralateral effect. Lidocaine, but not colchicine, when applied previously to the nerves midway between the sectioning site and the spinal cord, inhibited the contralateral increase in AA incorporation. It is concluded that electrical signals, crossing through the spinal cord, are responsible for the development of the contralateral effect. Both the nature of the proteins and the significance of the contralateral effect are matters for speculation

    Full Text Available Abstract Background Zoledronic acid is very widely used in patients with metastatic bone disease and osteoporosis. Only one case of bilateral uveitis was recently reported related to its use. Case presentation We report the first case of severe unilateral anterior uveitis in a patient with breast cancer and an intraocular lens. Following zoledronic acid infusion, the patient developed severe and dramatic right eye pain with decreased visual acuity within 24 hours and was found to have a fibrinous anterior uveitis of moderate severity The patient was treated with topical prednisone and atropine eyedrops and recovered slowly over several months. Conclusion Internists, oncologists, endocrinologists, and ophtalmologists should be aware of uveitis as a possible complication of zoledronic acid therapy. Patients should be instructed to report immediately to their physicians and treatment with topical prednisone and atropine eyedrops should be instituted immediately at the onset of symptoms. This report documents anterior uveitis as a complication of zoledronic acid therapy. This reaction could be an idiosyncratic one but further research may shed more light on the etiology.

    Full Text Available We aimed to report a rarely observed case of unilateral epicapsular star and the visual impairment developed secondary to it. A 8-year-old girl presented with a complaint of blurred vision in the right eye; best-corrected visual acuity was 0.7 in the right eye and 1.0 in the left eye. Near visual acuity was J1 in the right eye and J1+ in the left eye. The patient had no systemic disease and no clinical findings such as ocular inflammation, trauma, or history of use of topical and systemic drug. On biomicroscopic examination, no pigment deposition was observed in the cornea of both eyes and anterior chamber was normal. The anterior capsule of the lens in the right eye demonstrated dense pigment depositions centrally which were obscuring the pupillary axis. Iris translumination defect was not seen. Gonioscopy was performed and no pigment deposition was seen in the iridocorneal angle. Fundus examination revealed no pathology in the vitreous, posterior pole, and peripheral retina. In the absence of signs of intraocular inflammation and other causes of primary or secondary pigment dispersion, it is likely that the pigmented cells were implanted on the lens surface in utero from the developing iris pigment epithelium. In such cases, visual impairment should be detected in early period, and the strict follow-up is of utmost importance. (Turk J Ophthalmol 2014; 44: 493-5

    To evaluate the complexity of vestibular-ocular reflex (VOR) in patients with acute unilateral vestibular loss (AUVL) via entropy analysis of head impulses. Horizontal head impulse test (HIT) with high-velocity alternating directions was used to evaluate 12 participants with AUVL and 16 healthy volunteers. Wireless electro-oculography and electronic gyrometry were used to acquire eye positional signals and head velocity signals. The eye velocity signals were then obtained through differentiation, band-pass filtering. The approximate entropy of eye velocity to head velocity (R ApEn ) was used to evaluate chaos property. VOR gain, gain asymmetry ratio, and R ApEn asymmetry ratio were also used to compare the groups. For the lesion-side HIT of the patient group, the mean VOR gain was significantly lower and the mean R ApEn was significantly greater compared with both nonlesion-side HIT and healthy controls (p Entropy and gain analysis of HIT using wireless electro-oculography system could be used to detect the VOR dysfunctions of AUVL and may become effective methods for evaluating vestibular disorders.

    Backgroud: The fronto-ethmoidal mucocele is a benign condition leading commonly to limited eye movement or ocular pain but it could also induce visual acuity impairment by compressing the optic nerve Aim: To discuss, through a case report, different ophthalmologic manifestations of the fronto-ethmoidalmucocele. Reported case: A 46-years-old man with no general history consulted for a bilateral ocular redness and itching. He reported, however, a mild protrusion of his left globe evolving for oneyear. The clinical examination revealed a unilateral proptosis in the left eye with a discrete limitation of theadduction. A brain and orbital computer tomography (CT)and a magnetic resonance imaging(MRI)revealed a grade I exophthalmos caused by an oval formation of fluid density in the left anterior and posterior ethmoidal cells in addition to the frontal sinus,driving theeyeball and internal oculomotor muscles back and out.The patient was referred to otorhinolaryngology department for a precocious surgical management. The ophtalmologic manifestations of the disease depend on the location, the size of the formation and involvement of adjacent structures. The loss of vision and the apex syndrome due to the compressionof the ocular globe are the most serious complications.

    Hospital or institutional policies that guide the activity of nurses in the care of their patients may, at times, be controversial. Nursing staffs often act as gatekeepers of patient care activities and the implementers of institutional policy. When nurses raise questions as to the appropriateness of a given policy statement, the institution should take serious notice and, perhaps, even study the policy outcomes that relate to the concerns expressed by the nursing staff. This article introduces a policy that originally prompted serious concerns by the nursing staff at one institution. The nursing staff voiced their concerns regarding a revision in the DNR policy that would allow physicians to write unilateral do-not-resuscitate (DNR) orders. Because of this, a review of this policy took place and the results were used to dispel unfounded concerns and also to improve the use of the policy. This article may help nursing administrators to understand better the importance of policy-related studies and it may also encourage nurses to question policy statements and guidelines that may present some concerns. Enhanced patient care will ultimately result by such teamwork and scholarly activity.

    2015-08-01

    Full Text Available The cylindrical cam ridge of the indexer is a spatial curved surface, which is difficult to design and machine. The cylindrical cam has some defects after machining because conventional machining methods have inaccuracies. This article aims at proposing a precise way to machine an indexing cam, using basic motion analysis and analytic geometry approach. Analytical methodology is first applied in the cam’s motion analysis, to obtain an error-free cam follower’s trajectory formula, and then separate the continuous trajectory curve by thousandth resolution, to create a three-dimensional discrete trajectory curve. Planar formulae and spherical formulae can be built on the loci. Based on the machine principle, the cutting cutter’s position and orientation will be taken into account. This article calculates the formula set as presented previously and obtains the ultimate cutter path coordinate value. The new error-free cutter path trajectory is called the unilateral machining trajectory. The earned results will compile into numerical control processing schedule. This processing methodology gives a convenient and precision way to manufacture a cylindrical indexing cam. Experimental results are also well supported.

    Dysphonia is considered a major symptom of unilateral vocal fold paralysis (UVFP). Besides this, many patients complain of further symptoms such as dysphagia and dyspnea, which might not be expected to such an extent. The aim of this survey was to elucidate these symptoms in a cohort of patients with UVFP. Sixty-three patients (22 men, 41 women) suffering from UVFP were interviewed. Therefore we developed a questionnaire dealing with each of the three symptom categories: voice production, swallowing and breathing. All of the surveyed patients reported voice impairment, almost 60% complained of swallowing problems after the onset of paralysis. Seventy-five percent reported a subjectively impaired breathing sensation, not just phonatory dyspnea but during everyday physical activity as well. Our study revealed a certain discrepancy between objectively assessed laryngoscopic findings and subjective symptoms. A majority of patients suffered from an impairment in each of the three laryngeal functions (dysphonia, dysphagia and dyspnea). The latter two differ from the classic approach to this condition but must be considered as well in clinical diagnostics and therapy. Copyright © 2010 S. Karger AG, Basel.

    The objective of this study was to determine the extent to which altered loading in the temporomandibular joint (TMJ), as might be associated with a malocclusion, drives degeneration of articulating surfaces in the TMJ. We therefore sought to quantify the effects of altered joint loading on the mechanical properties and biochemical content and distribution of TMJ fibrocartilage in the rabbit. Altered TMJ loading was induced with a 1mm splint placed unilaterally over the maxillary and mandibular molars for 6 weeks. At that time, TMJ fibrocartilage was assessed by compression testing, biochemical content (collagen, glycosaminoglycan (GAG), DNA) and distribution (histology), for both the TMJ disc and the condylar fibrocartilage. There were no changes in the TMJ disc for any of the parameters tested. The condylar fibrocartilage from the splinted animals was significantly stiffer and the DNA content was significantly lower than that in control animals. There was significant remodeling in the condylar fibrocartilage layers as manifested by a change in GAG and collagen II distribution and a loss of defined cell layers. A connection between the compressive properties of TMJ condylar fibrocartilage after 6 weeks of splinting and the changes in histology was observed. These results suggest a change in joint loading leads to condylar damage, which may contribute to pain associated with at least some forms of TMJ disease. Copyright © 2014 Elsevier Ltd.

    Full Text Available PURPOSE: Objective quantifications of facial asymmetry in patients with Unilateral Condylar Hyperplasia (UCH have not yet been described in literature. The aim of this study was to objectively quantify soft-tissue asymmetry in patients with UCH and to compare the findings with a control group using a new method. MATERIAL AND METHODS: Thirty 3D photographs of patients diagnosed with UCH were compared with 30 3D photographs of healthy controls. As UCH presents particularly in the mandible, a new method was used to isolate the lower part of the face to evaluate asymmetry of this part separately. The new method was validated by two observers using 3D photographs of five patients and five controls. RESULTS: A significant difference (0.79 mm between patients and controls whole face asymmetry was found. Intra- and inter-observer differences of 0.011 mm (-0.034-0.011 and 0.017 mm (-0.007-0.042 respectively were found. These differences are irrelevant in clinical practice. CONCLUSION: After objective quantification, a significant difference was identified in soft-tissue asymmetry between patients with UCH and controls. The method used to isolate mandibular asymmetry was found to be valid and a suitable tool to evaluate facial asymmetry.

    To establish the surgical results and residual symptoms in 48 cases with unilateral congenital superior oblique muscle palsy that had surgical intervention to the vertical muscles alone. Myectomy and concomitant disinsertion of the inferior oblique (IO) muscle was performed in 38 cases and myectomy and concomitant IO disinsertion and recession of the superior rectus muscle in the ipsilateral eye was performed in 10 cases. The preoperative and postoperative vertical deviation values and surgical results were compared. Of the patients who had myectomy and concomitant IO disinsertion, 74% achieved an "excellent" result, 21% a "good" result, and 5% a "poor" result postoperatively. The difference in deviation between preoperative and postoperative values was statistically significant (P < .001). Of the patients who had myectomy and concomitant inferior oblique disinsertion and ipsilateral superior rectus recession, 50% achieved an "excellent" result, 20% a "good" result, and 30% a "poor" result postoperatively. The difference in deviation between preoperative and postoperative values was statistically significant (P < .001). Both procedures are effective and successful in patients with superior oblique muscle palsy, but a secondary surgery may be required. Copyright 2012, SLACK Incorporated.

    This case report depicts the clinical course of a female patient with unilateral retinitis pigmentosa, who first presented at the age of 12 years. Fundus photography at the time revealed unilateral pigmentary retinopathy, which was associated with extinguished electroretinogram (ERG) signal. At 35 years of age, fundus examination revealed deterioration of pre-existing unilateral pigmentary retinopathy with progressive visual field defect detected on Goldmann visual field testing. ERG findings remained unchanged and multifocal ERG showed unilateral decrease in amplitude in the affected eye. The patient was referred for genetic counselling. Next-generation sequencing identified a deleterious heterozygous c.118T>G (p.Cys40Gly) mutation in the CLRN1 gene. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    To report the outcome of conservative management of unilateral fractures of the mandibular rami in horses. Retrospective case series. 24 client-owned horses with unilateral mandibular fractures METHODS: Medical records (January 2000-January 2014) of horses with unilateral mandibular ramus fractures were retrieved. Only conservatively managed horses with follow-up information were included. Follow-up information on clinical outcome was retrieved from the medical records (n=11) or obtained by telephone interviews with the owners or trainers (n=13). Twenty-three horses (96%) returned to their previous or intended use and had no clinically evident masticatory or fracture healing-related problems at the time of follow-up. The owner of 1 horse (4%) reported it had tooth loosening, feed impaction, and masticatory problems. Conservative management of unilateral fractures of the mandibular rami is a treatment option in horses. © Copyright 2016 by The American College of Veterinary Surgeons.

    2015-01-01

    Application of bilateral hearing devices in bilateral hearing loss and unilateral application in unilateral hearing loss (second ear with normal hearing) does not a priori lead to binaural hearing. An overview is presented on several measures of binaural benefits that have been used in patients with unilateral or bilateral deafness using one or two cochlear implants, respectively, and in patients with unilateral or bilateral conductive/mixed hearing loss using one or two percutaneous bone conduction implants (BCDs), respectively. Overall, according to this overview, the most significant and sensitive measure is the benefit in directional hearing. Measures using speech (viz. binaural summation, binaural squelch or use of the head shadow effect) showed minor benefits, except for patients with bilateral conductive/mixed hearing loss using two BCDs. Although less feasible in daily practise, the binaural masking level difference test seems to be a promising option in the assessment of binaural function. © 2015 S. Karger AG, Basel.

    Full Text Available Objetivo Describir y analizar una técnica de osteosíntesis palmar de radio distal con preservación del pronador cuadrado. Material y Métodos Se revisaron, en forma retrospectiva, 24 pacientes operados con esta técnica (16 mujeres y 8 hombres; edad promedio 65 años. Doce fracturas eran de tipo A; 7, de tipo B y 5, de tipo C. La técnica quirúrgica consiste en practicar una incisión cutánea de 25 mm y profundizar hasta observar el pronador cuadrado. Sin seccionarlo, se realiza una disección de su borde distal, a fin de introducir la placa bloqueada volar por debajo del músculo. Se colocan los tornillos distales bajo visión directa y los tornillos proximales, en forma percutánea. La evaluación posoperatoria se llevó a cabo mediante análisis clínico-funcional y radiográfico. Resultados En el último control, todos los pacientes presentaban signos clínicos y radiográficos de consolidación ósea. El puntaje en la escala DASH fue, en promedio, de 4,8. Se observó una inclinación palmar posoperatoria de la superficie articular del radio de 14,3º promedio y una inclinación radial de 26,3º promedio. No se detectaron complicaciones relacionadas con la fractura, el implante o la herida quirúrgica en ninguno de los controles posoperatorios. Conclusiones Sin bien no existe bibliografía que demuestre que la técnica mininvasiva sea superior, sostenemos que el hecho de obtener resultados similares con ambos abordajes (mininvasivo y convencional justifica llevar a cabo esta técnica con preservación del pronador cuadrado, sobre todo en los pacientes preocupados por el aspecto cosmético de la cicatriz.

    Objective: It's a study of the collateral circulation secondary to unilateral and bilateral internal carotid artery (ICA) severe stenosis or occlusion using digital subtract angiography (DSA) and magnetic resonance angiography (MRA). Methods: Ninty-five patients with ICA stenosis or occlusion were diagnosed by DSA or MRA. Forty-four patients were assessed by DSA, and fifty-one patients were evaluated by MRA, who were divided into two groups of the unilateral and bilateral involvement. DSA, MRA findings were analyzed, by which the patterns of the collateral circulation were comparatively studied. Results: The presence rate of anterior communicating artery (AcoA) in the unilateral group on DSA and MRA was significantly higher than that in the bilateral group (P 0.05). On DSA, the presence rate of ophthalmic artery (OphA) in the unilateral and bilateral groups had no significant difference between the two groups. The augmentation rate of the OphA in the bilateral group was significantly higher than that in the unilateral group (P<0.05). The presence rate of leptomeningeal anastomosis in the bilateral group was significantly higher than that in the unilateral group on DSA and MRA (P<0.01). Conclusion: In patients with the unilateral and bilateral ICA stenosis or occlusion, the collateral circulation formats in different patterns. The major collateral pathways secondary to the unilateral ICA stenosis or occlusion are AcoA and ispilateral PCoA, while to the bilateral ICA stenosis or' occlusion are PCoA, OPhA, and leptomeningeal anastomosis.

    Conclusion: To our knowledge, this is the first report of unilateral periventricular heterotopia associated with Ehlers–Danlos syndrome. We first hypothesized a mosaicism as the cause of both, a unilateral localization of the heterotopias and a favorable long-term course with good response to anticonvulsant therapy; however, intriguingly, we could not demonstrate a mosaicism as the genetic condition in our patient and the neuroradiological findings and the favorable clinical outcome still remain unexplained.

    To clarify advantages of unilateral electrode placement as an optimisation technique for electroconvulsive therapy (ECT) for depression, aims were to meta-analyse unilateral ECT effects on cognitive performance relative to: (1) bitemporal electrode placement, (2) electrical dosage, and (3) time interval between final treatment and cognitive reassessment. Relevant electronic databases were systematically searched through May 2009, using the terms: "electroconvulsive therapy" and ["cogniti∗", "neuropsycholog∗", "memory", "attention", "executive", "spatial", or "intellectual"]. Inclusion criteria were: independent study of depressed patients receiving unilateral or bitemporal brief-pulse ECT; within-subjects design; use of objective cognitive assessments; available mean electrical dosage for unilateral samples. Standardized pre-post ECT weighted effect sizes were computed and pooled within 16 cognitive domains by a mixed-effects model. Thirty-nine studies (1415 patients) were meta-analysed. Up to three days after final treatment, unilateral ECT was associated with significantly smaller decreases in global cognition, delayed verbal memory retrieval, and autobiographical memory, compared to bitemporal ECT. Significant publication bias was found for autobiographical memory, favouring reporting of larger percentage loss. Higher unilateral ECT electrical dosage predicted larger decreases in verbal learning, delayed verbal memory retrieval, visual recognition, and semantic memory retrieval. When retested more than three days after completing ECT, no significant differences remained between the two electrode placements; for unilateral ECT, electrical dosage no longer predicted cognitive performance whereas increasing interval between final treatment and retesting predicted growing improvement in some variables. This interval is a more useful long-term predictor of cognitive function than electrode placement or electrical dosage following unilateral ECT. Copyright © 2010

J Strength Cond Res 25(12): 3311-3318, 2011-The purpose of this study was to examine the effects of unilateral and bilateral plyometric exercise on peak power and jumping performance during different stages of a 12-week training and detraining in women. Forty-nine untrained but physically active female college students were randomly assigned to 1 of 3 groups: unilateral plyometric group (n = 16), bilateral plyometric group (BLE; n = 18), and a control group (n = 15). Peak power and jumping ability were assessed by means of the alternate leg tests (10-second Wingate test and 5 alternate leg bounds), bilateral leg test (countermovement jump [CMJ]) and unilateral leg test (unilateral CMJ). Performance indicators were measured pretraining, midtraining, posttraining, and detraining. Differences between dependent variables were assessed with a 3 × 4 (group × time) repeated analysis of variance with Tukey's post hoc test applied where appropriate. Effect size was calculated to determine the magnitude of significant differences between the researched parameters. Only the unilateral plyometric training produced significant (p 0.05) decrease power and jumping ability in all tests during detraining. These results suggest that unilateral plyometric exercises produce power and jumping performance during a shorter period when compared to bilateral plyometric exercises but achieved performance gains last longer after bilateral plyometric training. Practitioners should consider the inclusion of both unilateral and bilateral modes of plyometric exercise to elicit rapid improvements and guard against detraining.

    Full Text Available Most unilateral pedicle stress fractures occur on the contralateral side of patients with unilateral spondylolysis. However, there are few reports of unilateral pedicle stress fractures in patients with bilateral spondylolysis and spondylolisthesis. We report a unique case of unilateral pedicle stress fracture in a long-term hemodialysis patient with isthmic spondylolisthesis. A 65-year-old man who had undergone hemodialysis presented with lower back pain that had persisted for several years. The patient experienced severe right lower extremity pain with no history of trauma. Computed tomography revealed unilateral pedicle fracture with bilateral L5 spondylolysis and spondylolisthesis with progression of scoliosis. The patient underwent Gill laminectomy of L5 with pedicle screw fixation at L4-S1 and interbody fusion at L5-S1. The patient’s leg pain ceased immediately, and he began walking without leg pain. In our present patient, development of scoliosis caused by destructive spondyloarthropathy may have contributed to a unilateral pedicle fracture.

    2009-01-01

    Objectives In this preliminary prospective study, we compared unilateral and bilateral thyroarytenoid muscle injections of Botulinum toxin (Dysport) in 31 patients with adductor spasmodic dysphonia, who had undergone more than 5 consecutive Dysport injections (either unilateral or bilateral) and had completed 5 concomitant self-rated efficacy and complication scores questionnaires related to the previous injections. We also developed a Neurophysiological Scoring (NPS) system which has utility in the treatment administration. Method and materials Data were gathered prospectively on voice improvement (self-rated 6 point scale), length of response and duration of complications (breathiness, cough, dysphagia and total voice loss). Injections were performed under electromyography (EMG) guidance. NPS scale was used to describe the EMG response. Dose and unilateral/bilateral injections were determined by clinical judgment based on previous response. Time intervals between injections were patient driven. Results Low dose unilateral Dysport injection was associated with no significant difference in the patient's outcome in terms of duration of action, voice score (VS) and complication rate when compared to bilateral injections. Unilateral injections were not associated with any post treatment total voice loss unlike the bilateral injections. Conclusion Unilateral low dose Dysport injections are recommended in the treatment of adductor spasmodic dysphonia. PMID:19852852

    Unilateral Graves' disease is a rare disease variant that can occur in a bilobar thyroid gland. We report the first documented case of unilateral Graves' disease in the left lobe of a bilobar thyroid gland and review the pertinent literature. A 48-year-old man presented in June 2010 with thyrotoxicosis. I-131 radioisotope uptake was elevated at 33.4%, and scintigraphy revealed that uptake of the radioisotope was uniformly increased in the left lobe of the thyroid gland. Ultrasonography of the thyroid gland revealed a non-nodular, enlarged, and heterogeneous left lobe; Doppler investigation of the lobe showed hypervascularity classically seen in Graves' disease. The right lobe of the thyroid, on the other hand, appeared homogeneous and hypovascular on ultrasonography. Thyroid-stimulating immunoglobulin was significantly elevated at 191% (reference range disease was the most likely diagnosis. As has occasionally been described in the literature, unilateral involvement of the thyroid gland is a rare presentation of Graves' disease. Pre-existing functional or structural differences (either congenital or acquired) between the two lobes may contribute to this rare presentation. To our knowledge, this is the first reported case of unilateral Graves' disease presenting in the left lobe of a bilobar thyroid gland. Although the pathophysiology of unilateral Graves's disease has not been clearly elucidated, clinicians should be aware that Graves' disease can present unilaterally in either lobe of the thyroid gland.

    The main aim of the present study was to assess the early diagnostic value of bronchoalveolar lavage (BAL) in radiation-induced lung injury in patients with breast carcinoma. Twenty-six females receiving postoperative radiotherapy for breast cancer were evaluated before and 0, 15, 30, 60 , and 180 days after radiotherapy. History, physical examination, chest radiographs, and pulmonary function tests were obtained. BAL, including lymphocyte subsets analysis, was limited to the second evaluation after radiotherapy. A group of 21 healthy females were used as control. Findings after radiotherapy in asymptomatic patients were compared with findings in a group of patients with radiation pneumonitis. Irradiated patients showed a significantly (p<0.01) greater percentage (29.5±15.7%) of BAL lymphocytes than controls (6.2±3.3%). No statistical differences existed in BAL findings between the irradiated and unirradiated sides of the chest. Percentages of BAL lymphocytes did not differ significantly between patients who developed subsequent pneumonitis (24.5±13.5%) and those who did not develop pneumonitis (32.8±16.5%). Patients with pneumonitis at the time of BAL had significantly higher (p<0.05) alveolar CD4 subset cells (24.8±10.2%) than asymptomatic patients (15.2±8.9%). Maximal reductions in total lung capacity (p<0.01), and residual volume (p<0.05) occurred 60 days after irradiation.

    The main aim of the present study was to assess the early diagnostic value of bronchoalveolar lavage (BAL) in radiation-induced lung injury in patients with breast carcinoma. Twenty-six females receiving postoperative radiotherapy for breast cancer were evaluated before and 0, 15, 30, 60 , and 180 days after radiotherapy. History, physical examination, chest radiographs, and pulmonary function tests were obtained. BAL, including lymphocyte subsets analysis, was limited to the second evaluation after radiotherapy. A group of 21 healthy females were used as control. Findings after radiotherapy in asymptomatic patients were compared with findings in a group of patients with radiation pneumonitis. Irradiated patients showed a significantly (p<0.01) greater percentage (29.5{+-}15.7%) of BAL lymphocytes than controls (6.2{+-}3.3%). No statistical differences existed in BAL findings between the irradiated and unirradiated sides of the chest. Percentages of BAL lymphocytes did not differ significantly between patients who developed subsequent pneumonitis (24.5{+-}13.5%) and those who did not develop pneumonitis (32.8{+-}16.5%). Patients with pneumonitis at the time of BAL had significantly higher (p<0.05) alveolar CD4 subset cells (24.8{+-}10.2%) than asymptomatic patients (15.2{+-}8.9%). Maximal reductions in total lung capacity (p<0.01), and residual volume (p<0.05) occurred 60 days after irradiation. The early lymphocytic alveolitis induced by unilateral thoracic radiotherapy in most patients with breast cancer is always bilateral and does not predict the subsequent development of radiological evidence of pneumonitis.

    Unilateral vocal fold paralysis (UVFP) is a complication associated with cardiothoracic procedures that presents clinically as dysphonia and/or dysphagia with or without aspiration. The literature lacks both data on recovery of mobility and consensus on best management. Herein, our goals are to 1) Identify cardiothoracic procedures associated with symptomatic UVFP at our institution; 2) Review timing and nature of laryngology diagnosis and management; 3) Report spontaneous recovery rate of vocal fold mobility. Retrospective case series at single tertiary referral center between 2002 and 2015. 141 patients were included who underwent laryngology interventions (micronized acellular dermis injection laryngoplasty and/or type 1 thyroplasty) to treat symptomatic UVFP diagnosed subsequent to cardiothoracic surgery. Pulmonary procedures were most often associated with UVFP (n=50/141; 35.5%). 87.2% had left-sided paralysis (n=123/141). Median time to diagnosis was 42days (x¯=114±348). Over time, UVFP was diagnosed progressively earlier after cardiothoracic surgery. 63.4% of patients (n=95/141) underwent injection laryngoplasty as their initial intervention with median time from diagnosis to injection of 11days (x¯=29.6±54). 41.1% (n=58/141) ultimately underwent type 1 thyroplasty at a median of 232.5days (x¯=367±510.2) after cardiothoracic surgery. 10.2% (n=9/88) of those with adequate follow-up recovered full vocal fold mobility. Many cardiothoracic procedures are associated with symptomatic UVFP, predominantly left-sided. Our data showed poor recovery of vocal fold mobility relative to other studies. Early diagnosis and potential surgical medialization is important in the care of these patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Aortocaval fistula (AV in rat is a unique model of volume-overload congestive heart failure and cardiac hypertrophy. Living donor kidney transplantation is regarded as beneficial to allograft recipients and not particularly detrimental to the donors. Impact of AV on animals with mild renal dysfunction is not fully understood. In this study, we explored the effects of AV in unilateral nephrectomized (UNX rats.Adult male Sprague-Dawley (SD rats were divided into Sham (n = 10, UNX (right kidney remove, n = 10, AV (AV established between the levels of renal arteries and iliac bifurcation, n = 18 and UNX+AV (AV at one week after UNX, n = 22, respectively. Renal outcome was measured by glomerular filtration rate, effective renal plasma flow, fractional excretion of sodium, albuminuria, plasma creatinine, and cystatin C. Focal glomerulosclerosis (FGS incidence was evaluated by renal histology. Cardiac function was measured by echocardiography and hemodynamic measurements.UNX alone induced compensatory left kidney enlargement, increased plasma creatinine and cystatin C levels, and slightly reduced glomerular filtration rate and increased FGS. AV induced significant cardiac enlargement and hypertrophy and reduced cardiac function and increased FGS, these changes were aggravated in UNX+AV rats.Although UNX only induces minor renal dysfunction, additional chronic volume overload placement during the adaptation phase of the remaining kidney is associated with aggravated cardiac dysfunction and remodeling in UNX rats, suggesting special medical care is required for UNX or congenital monokidney subjects in case of chronic volume overload as in the case of pregnancy and hyperthyroidism to prevent further adverse cardiorenal events in these individuals.

    It has been suggested that developmental dyslexia involves various literacy, sensory, motor skill, and processing speed deficits. Some recent studies have shown that individuals with developmental dyslexia exhibit implicit motor learning deficits, which may be related to cerebellar functioning. However, previous studies on implicit motor learning in developmental dyslexics have produced conflicting results. Findings from cerebellar lesion patients have shown that patients' implicit motor learning performance varied when different hands were used to complete tasks. This suggests that dyslexia may have different effects on implicit motor learning between the two hands if cerebellar dysfunction is involved. To specify this question, we used a one-handed version of a serial reaction time task to compare the performance of 27 Chinese children with developmental dyslexics with another 27 age-matched children without reading difficulties. All the subjects were students from two primary schools, Grades 4 to 6. The results showed that children with developmental dyslexic responded more slowly than nondyslexic children, and exhibited no implicit motor learning in the condition of left-hand response. In contrast, there was no significant difference in reaction time between two groups of children when they used the right hand to respond. This finding indicates that children with developmental dyslexia exhibited normal motor skill and implicit motor learning ability provided the right hand was used. Taken together, these results suggested that Chinese children with developmental dyslexia exhibit unilateral deficits in motor skill and implicit motor learning in the left hand. Our findings lend partial support to the cerebellar deficit theory of developmental dyslexia.

    Partial unilateral lentiginosis (PUL) is a rare pigmentation disorder characterized by numerous lentigines with sharp margins in the midline in one or more dermatomes. Its segmental pattern suggests that this presentation accompanied by café-au-lait spots, Lisch nodule or neurofibromas has a close relationship with mosaic neurofibromatosis type 1 or segmental neurofibromatosis (NF) in particular. In a group of 16 patients with PUL, who presented at the dermatology outpatient clinic between 1998 and 2015, an examination was made of consanguineous marriage in the family history, the presence of a similar lesion or NF in first-degree relatives, neurofibroma in the physical examination, the involvement pattern, axillary/inguinal freckling and the presence and number of café-au-lait spots. The ophthalmological examination investigated Lisch nodule and optic glioma. The skeletal system was examined for NF involvement. Of 16 patients, 13 (81.2%) were female and three (18.8%) were male with a mean age of 31.19 years (range, 15-48). There was no family history of PUL in any case. Consanguineous marriage was absent in 15 patients (93.8%). While there were accompanying café-au-lait spots in three patients (18.8%). Lisch nodule was an accompanying finding in three patients (18.8%). Axillary freckling was detected in four (25%) patients. Neurofibroma was found in only one patient. Although café-au-lait spots, axillary freckling, neurofibroma and Lisch nodule were present in a small number of the patients, the presence of the findings may be considered to be specific to NF suggests that PUL is a variant of mosaic NF-1. Genetic studies will help to further elucidate this subject. © 2016 Japanese Dermatological Association.

  1. Unilateral optic neuropathy following subdural hematoma: a case report

    Full Text Available Abstract Introduction Unilateral optic neuropathy is commonly due to a prechiasmatic affliction of the anterior visual pathway, while losses in visual hemifields result from the damage to brain hemispheres. Here we report the unusual case of a patient who suffered from acute optic neuropathy following hemispherical subdural hematoma. Although confirmed up to now only through necropsy studies, our case strongly suggests a local, microcirculatory deficit identified through magnetic resonance imaging in vivo. Case presentation A 70-year-old Caucasian German who developed a massive left hemispheric subdural hematoma under oral anticoagulation presented with acute, severe visual impairment on his left eye, which was noticed after surgical decompression. Neurologic and ophthalmologic examinations indicated sinistral optic neuropathy with visual acuity reduced nearly to amaurosis. Ocular pathology such as vitreous body hemorrhage, papilledema, and central retinal artery occlusion were excluded. An orbital lesion was ruled out by means of orbital magnetic resonance imaging. However, cerebral diffusion-weighted imaging and T2 maps of magnetic resonance imaging revealed a circumscribed ischemic lesion within the edematous, slightly herniated temporomesial lobe within the immediate vicinity of the affected optic nerve. Thus, the clinical course and morphologic magnetic resonance imaging findings suggest the occurrence of pressure-induced posterior ischemic optic neuropathy due to microcirculatory compromise. Conclusion Although lesions of the second cranial nerve following subdural hematoma have been reported individually, their pathogenesis was preferentially proposed from autopsy studies. Here we discuss a dual, pressure-induced and secondarily ischemic pathomechanism on the base of in vivo magnetic resonance imaging diagnostics which may remain unconsidered by computed tomography.

    Locomotor adaptation enables walkers to modify strategies when faced with challenging walking conditions. While a variety of neurological injuries can impair locomotor adaptability, the effect of a lower extremity amputation on adaptability is poorly understood. Determine if locomotor adaptability is impaired in persons with unilateral transtibial amputation (TTA). The locomotor adaptability of 10 persons with a TTA and 8 persons without an amputation was tested while walking on a split-belt treadmill with the parallel belts running at the same (tied) or different (split) speeds. In the split condition, participants walked for 15 minutes with the respective belts moving at 0.5 m/s and 1.5 m/s. Temporal spatial symmetry measures were used to evaluate reactive accommodations to the perturbation, and the adaptive/de-adaptive response. Persons with TTA and the reference group of persons without amputation both demonstrated highly symmetric walking at baseline. During the split adaptation and tied post-adaptation walking both groups responded with the expected reactive accommodations. Likewise, adaptive and de-adaptive responses were observed. The magnitude and rate of change in the adaptive and de-adaptive responses were similar for persons with TTA and those without an amputation. Furthermore, adaptability was no different based on belt assignment for the prosthetic limb during split adaptation walking. Reactive changes and locomotor adaptation in response to a challenging and novel walking condition were similar in persons with TTA to those without an amputation. Results suggest persons with TTA have the capacity to modify locomotor strategies to meet the demands of most walking conditions despite challenges imposed by an amputation and use of a prosthetic limb.

    To evaluate the cost-effectiveness of obtaining a magnetic resonance imaging (MRI) in patients with abnormal electronystagmography (ENG) or videonystagmography (VNG) results. Retrospective chart review. Academic specialty center. Patients presenting with vertigo between January 1, 2010, and August 30, 2013. Patients who fit the following abnormal criteria were included in the study: unilateral caloric weakness (≥20%), abnormal ocular motor testing, and nystagmus on positional testing. Patients with abnormal findings who then underwent MRI with gadolinium were evaluated. Of the 1,996 charts reviewed, there were 1,358 patients who met the inclusion criteria. The average age of these patients was 62 years (12-94 yr). The male:female ratio was approximately 1:2. Of the 1,358 patients, 253 received an MRI with the following pathologies: four vestibular schwannomas, three subcortical/periventricular white matter changes suspicious for demyelinating disease, four acute cerebellar/posterior circulation infarct, two vertebral artery narrowing, one pseudomeningocele of internal auditory canal, and two white matter changes indicative of migraines. The positive detection rate on MRI was 5.5% based on MRI findings of treatable pathologies causing vertigo. Average cost of an MRI is $1,200, thereby making the average cost of identifying a patient with a positive MRI finding $15,180. In our study, those patients with a positive MRI had a constellation of symptoms and findings (asymmetric sensorineural hearing loss, tinnitus, vertigo, and abnormal ENG/VNG). Cost-effectiveness can be improved by ordering an MRI only when clinical examination and VNG point toward a central pathology. Clinical examination and appropriate testing should be factored when considering the cost-effectiveness of obtaining an MRI in patients with abnormal ENG/VNG findings.

    Full Text Available El objetivo de este trabajo es describir y analizar los cambios en la definición de la diabetes como enfermedad y la relación con las transformaciones en su abordaje terapéutico. Se realizó un análisis de contenido sobre los artículos, guías y consensos publicados por la Sociedad Argentina de Diabetes (SAD y la Asociación Latinoamericana de Diabetes (ALAD entre los años 1980 y 2010. Se desagregaron las diferentes clasificaciones, los valores considerados normales para definir a una persona como diabética y el tratamiento, analizando críticamente los cambios y modificaciones encontrados con el auxilio de categorías como medicalización, riesgo y estilos de vida. Como resultado del análisis hemos podido observar cómo el creciente proceso de medicalización, la dependencia con respecto al conocimiento científico de países centrales, los intereses de la industria farmacéutica y el lugar central del tratamiento farmacológico se inscriben en el abordaje de la diabetes y se hacen visibles a través de los cambios sucedidos en los últimos 30 años.

  5. Associations of unilateral whisker and olfactory signals induce synapse formation and memory cell recruitment in bilateral barrel cortices: cellular mechanism for unilateral training toward bilateral memory

    2016-12-01

    Full Text Available Somatosensory signals and operative skills learned by unilateral limbs can be retrieved bilaterally. In terms of cellular mechanism underlying this unilateral learning toward bilateral memory, we hypothesized that associative memory cells in bilateral cortices and synapse innervations between them were produced. In the examination of this hypothesis, we have observed that paired unilateral whisker and odor stimulations led to odorant-induced whisker motions in bilateral sides, which were attenuated by inhibiting the activity of barrel cortices. In the mice that showed bilateral cross-modal responses, the neurons in both sides of barrel cortices became to encode this new odor signal alongside the innate whisker signal. Axon projections and synapse formations from the barrel cortex, which was co-activated with the piriform cortex, toward its contralateral barrel cortex were upregulated. Glutamatergic synaptic transmission in bilateral barrel cortices was upregulated and GABAergic synaptic transmission was downregulated. The associative activations of the sensory cortices facilitate new axon projection, glutamatergic synapse formation and GABAergic synapse downregulation, which drive the neurons to be recruited as associative memory cells in the bilateral cortices. Our data reveals the productions of associative memory cells and synapse innervations in bilateral sensory cortices for unilateral training toward bilateral memory.

Entre ellas, los adenomas hipofisarios constituyen el tercer tipo de tumor primario más frecuente en el sistema nervioso central. Los abordajes quirúrgicos empleados para su solución son transcraneales y transesfenoidales. Analizamos aquí los resultados de la cirugía selar durante los últimos 8 años en el hospital "Hermanos Ameijeiras", a través de variables como abordaje, tipos de lesión, características imagenológicas y endocrinológicas, evolución posoperatoria, mortalidad y complicaciones. Se intervinieron 273 lesiones (18 transcraneales y 255 transesfenoidales, 222 adenomas (150 funcionantes y 72 no funcionantes, 27 Aracnoidoceles, 13 fístulas de líquido cefalorraquídeo y otras 11 lesiones tumorales. Los adenomas no funcionantes fueron 70 macroadenomas y 2 microadenomas, y los funcionantes 84 macroadenomas y 66 microadenomas. El control fue siempre superior en los microadenomas. Se resolvieron el 53,8 % de las fístulas. En pacientes con silla turca vacía, mejoró el defecto campimétrico en el 69,2 % y se resolvió la fístula en el 71,4. La evaluación por imágenes en el posoperatorio del resto de las lesiones arrojó que de 6 craneofaringiomas, en 5 predominantemente quísticos se logró exéresis total y en uno parcial. El resto de las lesiones se resecaron totalmente. La morbilidad operatoria fue 18,31 % en toda la serie, notablemente inferior en los abordajes transesfenoidales; la mortalidad, solo presente entre los abordajes transcraneales, representó el 0,73.

    We aimed to determine whether countermovement jumps (CMJs; unilateral and bilateral) performed in different directions assessed independent lower-limb power qualities, and if unilateral CMJs would better differentiate between elite and non-elite soccer players than the bilateral vertical (BV) CMJ. Elite (n=23; age, 18.1±1.0years) and non-elite (n=20; age, 22.3±2.7years) soccer players performed three BV, unilateral vertical (UV), unilateral horizontal-forward (UH) and unilateral medial (UM) CMJs. Jump performance (height and projectile range), kinetic and kinematic variables from ground reaction forces, and peak activation levels of the vastus lateralis and biceps femoris (BF) muscles from surface electromyography, were compared between jumps and groups of players. Peak vertical power (V-power) was greater in BV (220.2±30.1W/kg) compared to UV (144.1±16.2W/kg), which was greater than UH (86.7±18.3W/kg) and UM (85.5±13.5W/kg) (all, pprojectile range than non-elite (51.6±15.4 vs. 40.4±10.4cm, p=0.009). We have shown that UH, UV and UM CMJs assess distinct lower-limb muscular power capabilities in soccer players. Furthermore, as elite players outperformed non-elite players during unilateral but not BV CMJs, unilateral CMJs in different directions should be included in soccer-specific muscular power assessment and talent identification protocols, rather than the BV CMJ.

    Full Text Available Abstract Background The existence of unilateral adrenal hyperplasia (AH has been considered a rare cause of primary hyperaldosteronism (PA. Methods In a prospective study we screened for PA in a non-selected (NSP and selected hypertensive population (SP, to define the cause of PA. We included 353 consecutive patients with hypertension; age 20 to 88 years, 165 women and 188 men, from a university-based Hypertension and Nephrology Outpatient clinics (123 SP and two primary care centres, (230 NSP from the same catch-up area. Serum aldosterone and plasma renin activity (PRA were measured and the ARR calculated. Verifying diagnostic procedure was performed in patients with both elevated aldosterone and ARR. Patients diagnosed with PA were invited for adrenal venous sampling (AVS and offered laparoscopic adrenalectomy when AVS found the disease to be unilateral. Results After screening, 46 patients, 13% of the whole population (22.8% SP and 7.8% NSP had aldosterone and ARR above the locally defined cut-off limits (0.43 nmol/l and 1.28 respectively. After diagnostic verification, 20 patients (6% had PA, (14.5% SP and 1.4% NSP. Imaging diagnostic procedures with CT-scans and scintigraphy were inconclusive. AVS, performed in 15 patients verified bilateral disease in 4 and unilateral in 10 patients. One AVS failed. After laparoscopic adrenalectomy, 4 patients were found to have adenoma and 5 unilateral AH. One patient denied operation. Conclusion The prevalence of PA was in agreement with previous studies. The study finds unilateral PA common and unilateral AH as half of those cases. As may be suspected PA is found in much higher frequency in specialised hypertensive units compared to primary care centers. AVS was mandatory in diagnosis of unilateral PA.

    Full Text Available This study was designed to investigate the influence of saline injections as epidural top-up on the sensory block duration, quality and hemodynamic effects of unilateral spinal anesthesia. The cases from ASA I-Il containing of 18-65 age group were randomly separated into three groups. For the purpose of unilateral spinal anesthesia, 6 mg 0.5% ‘heavy’ bupivacaine and for the purpose of epidural top-up, 10 mL saline were applied to the each patients of the groups. The study protocol was designed as:Ist group: Coming after the epidural catheter installation, unilateral spinal anesthesia was applied (n=20.IInd group: At first, unilateral spinal anesthesia was applied and after one minute, epidural top-up was done via the pre-installed epidural catheter (n=20.IIIrd group: At first the epidural catheter was installed and epidural top-up was applied. After one minute, unilateral spinal anesthesia was fulfilled (n=2O. Starting from the pre-anesthesic period, the hemodynamic data and following the anesthesia, the sensorial and motor block levels were recorded and evaluated.As the outcome of the inter-groups comparison of heart rate and mean arterial pressure, a statistically note-worthy differance was not determined; statistically significant but clinically acceptable hemodynamic changes were observed in intra-group evaluations, when the data was compared with control levels. The sensorial block levels were significantly higher in group II and significantly lower in group III.The application of 10 mL saline via epidural catheter 1 minute after the unilateral spinal anesthesia and remaining the patient leaning on the side of the extremity to be operated for 15 minutes improves the sensory block level of unilateral spinal anesthesia. It is determined that, for the lower extremity surgical operations with 1-1.5 hour estimated period, this method alone can be a worthwhile alternative.

    This study investigated the distractive effect of a unilateral pivot splint on patients with unilateral disc displacement without reduction. The study group was comprised of 18 patients who had no history of treatment with removable prosthetic restorations of molars, premolars, or canine teeth, and no previous treatment for temporomandibular disorder. Joint spaces measurements made on magnetic resonance images indicated the affected side to be narrower than the healthy side. Unilateral distraction splints were made for all patients. An ultrasonic motion analyzer was used to measure the vertical shift occurring on the affected side as patients closed their mouths with maximal force with the splint in their mouths. Closing with maximal force on the unilateral distraction splint led to a noticeable downward movement of the affected condyle. The findings of this study indicate that the TMJ condyle of patients with unilateral disc displacement without reduction may be unilaterally distracted if the articular space is narrowed.

    To test the hypothesis that functional disturbance of the neural network involving the inferior parietal lobule (IPL), anterior cingulate gyrus (ACG), dorsolateral frontal lobe (DLF), and thalamus (TH) as components of the right hemisphere underlies the development of unilateral spatial neglect (USN), cerebral perfusion was measured by 123 I-IMP SPECT in 32 patients with cerebrovascular right brain damage, 20 of whom had USN and 12 of whom did not. In analyzing the SPECT data, RI uptake in the four component regions and cerebellum (serving as a control) were estimated by symmetrically placing 'regions of interest' from both hemispheres on SPECT slices, most suitable for each region. The 'regional to cerebellar ratio' (R/CE ratio) for each component region was calculated and the values were compared. In the USN group, R/CE ratio values for each component region in the right hemisphere were significantly lower than those in the left, whereas in the non-USN group there was no right-left difference. When R/CE ratio values for each component region in the right hemisphere were compared between the USN and non-USN group, those for the IPL, ACG and TH were significantly lower in the USN group; the value for the DLF was also lower in the USN group, although the difference was not significant. Significantly lower values of R/CE for each component region in the right hemisphere were noticed when the regions showed apparent involvement on X-ray CT/MRI. Furthermore, in seven of the USN patients where lesions revealed by CT/MRI did not involve network components, the R/CE ratio values for the components in the right hemisphere were lower than those in the left; the difference was significant for the IPL, ACG and TH, but not for the DLF. It is suggested that functional disturbance of the neural network involving the IPL, ACG, DLF and TH in the right hemisphere might underlie the development of USN. (author)

En todos los casos la resección fue completa, sin recidivas durante el seguimiento. En un único caso se produjo una complicación mayor: una hemorragia postpolipectomía que se controló endoscópicamente. Conclusiones: la resección endoscópica de los tumores carcinoides, en pacientes bien seleccionados, es una técnica segura y eficaz permitiendo una resección completa en todos los casos con escasas complicaciones. La ecoendoscopia es la técnica de elección para seleccionar los pacientes candidatos a resección endoscópica.

    Bilateral three-compartment wrist arthrography was performed in 30 patients with unilateral post-traumatic wrist pain to assess the incidence of bilateral findings. The mean age of patients was 30 (range 18-55) years. Thirty-three percent of patients were normal bilaterally, 30% had unilateral communication in the symptomatic wrist, 30% had communications in both the symptomatic and asymptomatic wrists and 7% had communication in the asymptomatic wrist only. Unilateral three-compartment wrist arthrography is not recommended in the assessment of unilateral post-traumatic wrist pain; no advantage of three-compartment injection over radiocarpal injection alone was shown.

    Structural equation and Mei conserved quantity of Mei symmetry for Appell equations in holonomic systems with unilateral constraints are investigated. Appell equations and differential equations of motion for holonomic mechanic systems with unilateral constraints are established. The definition and the criterion of Mei symmetry for Appell equations in holonomic systems with unilateral constraints under the infinitesimal transformations of groups are also given. The expressions of the structural equation and Mei conserved quantity of Mei symmetry for Appell equations in holonomic systems with unilateral constraints expressed by Appell functions are obtained. An example is given to illustrate the application of the results. (general)

    To photoelastically examine load transfer by unilateral distal extension removable partial dentures with supporting and retentive components made of the lower stiffness polyacetal resins. A mandibular photoelastic model, with edentulous space distal to the right second premolar and missing the left first molar, was constructed to determine the load transmission characteristics of a unilateral distal extension base removable partial denture. Individual simulants were used for tooth structure, periodontal ligament, and alveolar bone. Three designs were fabricated: a major connector and clasps made from polyacetal resin, a metal framework as the major connector with polyacetal resin clasp and denture base, and a traditional metal framework I-bar removable partial denture. Simulated posterior bilateral and unilateral occlusal loads were applied to the removable partial dentures. Under bilateral and left side unilateral loading, the highest stress was observed adjacent to the left side posterior teeth with the polyacetal removable partial denture. The lowest stress was seen with the traditional metal framework. Unilateral loads on the right edentulous region produced similar distributed stress under the denture base with all three designs but a somewhat higher intensity with the polyacetal framework. The polyacetal resin removable partial denture concentrated the highest stresses to the abutment and the bone. The traditional metal framework I-bar removable partial denture most equitably distributed force. The hybrid design that combined a metal framework and polyacetal clasp and denture base may be a viable alternative when aesthetics are of primary concern.

    Unilateral acute pulmonary oedema (APO) is a rare radioclinical finding. It occurs secondary to multiple specific and rare pathological processes. Functional ischemic mitral regurgitation (FIMR) secondary to myocardial necrosis is one of the rare aetiologies involved in its pathogenesis. This concerns a 94-year-old male patient with a history of myocardial infarction who presented with a clinical picture of unilateral APO secondary to functional mitral regurgitation as a complication of myocardial necrosis. In addition to the clinical presentation and unilateral radiological findings, the diagnosis was based essentially on the electrocardiographic tracing, as well as changes in cardiac enzyme levels and transthoracic echocardiogram coupled with Doppler tissue imaging. This resulted after ruling out many differential diagnoses. Unilateral APO secondary to functional mitral regurgitation often presents diagnostic challenges and problems of initial management for the clinician. There are multiple aetiologies of acute unilateral pulmonary oedema, namely mechanical (re-expansion), lesional, vascular, bronchial obstructions, as well as iatrogenic causes, as is the case with some lung transplantations. As with all cases of APO, the treatment is based mainly on diuretics with high-flow oxygen therapy in association with an anticoagulant, which is usually effectively combined with a platelet aggregation inhibiting drug and sometimes with vasodilators and beta-blockers. Surgical treatment with valvuloplasty or valvular replacement appears to be the most effective means for preventing relapse.

    Patients with unilateral cleft lip and palate (CLP) deformities commonly develop nasal airway obstruction, necessitating septoplasty at the time of definitive rhinoplasty. We assessed the contribution of the bony septum to airway obstruction using computed tomography (CT) and cone beam CT (CBCT). A 2-year retrospective review of all subjects with unilateral CLP who underwent CBCT imaging (n = 22) and age-matched controls (n = 9) who underwent CT imaging was conducted. Control CT scans were used to determine the segment of nasal septum comprised almost entirely of bone. The CBCT of the nasal airway was assessed using Dolphin software to determine the contribution of the bony septum to septal deviation and airway obstruction. The nasal septum posterior to the midpoint between anterior and posterior nasal spine is comprised of 96% bone. The nasal airway associated with this posterior bony segment was 43.1% (P < 0.001) larger by volume on the non-cleft side in patients with unilateral CLP. The average septal deviation within the posterior bony segment was 5.4 mm, accounting for 74.4% of the maximal deviation within the nasal airway. The average airway stenosis within the posterior bony nasal airway was 0.45 mm (0-2.2 mm). In patients with unilateral CLP, the bony nasal septum can demonstrate significant deviation and airway stenosis. Surgeons should consider a bony septoplasty in their treatment algorithm in unilateral CLP patients who have reached skeletal maturity.

    Full Text Available Cardiorespiratory fitness assessment with leg cycle exercise testing may be influenced by motor impairments in the paretic lower extremity. Hence, this study examined the usefulness of a unilateral arm crank exercise test to assess cardiorespiratory fitness in individuals with stroke, including sixteen individuals with hemiparetic stroke (mean ± SD age, 56.4±7.5 years and 12 age- and sex-matched healthy controls. Participants performed the unilateral arm crank and leg cycle exercise tests to measure oxygen consumption (V˙O2 and heart rate at peak exercise. The V˙O2 at peak exercise during the unilateral arm crank exercise test was significantly lower in the stroke group than in the control group (p<0.001. In the stroke group, the heart rate at peak exercise during the unilateral arm crank exercise test did not significantly correlate with the Brunnstrom recovery stages of the lower extremity (p=0.137, whereas there was a significant correlation during the leg cycle exercise test (rho = 0.775, p<0.001. The unilateral arm crank exercise test can detect the deterioration of cardiorespiratory fitness independently of lower extremity motor impairment severity in individuals with hemiparetic stroke. This study is registered with UMIN000014733.

  1. Comparing bilateral to unilateral electroconvulsive therapy in a randomized study with EEG monitoring.

    1985-11-01

    In a double-blind study, 48 DSM-III depressed patients were randomly assigned to either the bilateral or nondominant unilateral electroconvulsive therapy (ECT) group. Seizure length was monitored by electroencephalography (EEG). When seizures were less than 25 s, ECT was immediately readministered. When length of seizure and pretreatment depression scores were controlled between the two groups, there were no differences in treatment effectiveness, as measured by the Hamilton Rating Scale for Depression and the Beck Depression Inventory, or in the number of treatments required. This was true after five ECT treatments as well as after completing all ECT treatments. Thus, when ECT is monitored via EEG to assure the presence of an adequate seizure, bilateral and nondominant unilateral placement yield equivalent responses. If ECT had not been readministered immediately following a missed seizure, unilateral patients would have had significantly more missed seizures. Significant difficulties in both short- and long-term memory were found 24 hours after the fifth ECT in bilateral but not in nondominant unilateral patients. No apparent memory loss could be documented in nondominant unilateral ECT.

    The injection of small doses of local anesthetic solutions through pencil-point directional needles and maintaining the lateral decubitus position for 15 to 30 minutes after the injection have been suggested to facilitate the unilateral distribution of spinal anesthesia. We evaluated the effects of hypobaric and hyperbaric bupivacaine in attempting to achieve unilateral spinal anesthesia for patients undergoing lower limb orthopedic surgery. Fifty patients were randomly allocated into 2 groups to receive either 1.5 mL hyperbaric bupivacaine 0.5% (7.5 mg; n = 25) or 4.2 mL hypobaric bupivacaine 0.18% (7.5 mg; n = 25). Drugs were administered at the L3-4 interspace with the patient in the lateral position. Patients remained in this position for 15 minutes before turning supine for the operation. Spinal block was assessed by pinprick and modified Bromage scale on both sides. Unilateral spinal block was observed in 20 patients in the hyperbaric group (80%) and in 19 patients in the hypobaric group (76%) while in the lateral position. However, 15 minutes after patients were turned supine, unilateral spinal anesthesia decreased to 68% of cases in the hyperbaric group and 24% of cases in the hypobaric group (P hyperbaric and hypobaric bupivacaine provided a rapid motor and sensory recovery and good hemodynamic stability, but more unilateral spinal block was achieved in patients in the hyperbaric group when compared with patients in the hypobaric group.

    The aim of this study was to compare the clinical effects and characteristics of hyperbaric and hypobaric levobupivacaine for unilateral spinal anaesthesia. Sixty patients were randomly allocated into two groups to receive either 7.5 mg (1.5 ml) hyperbaric levobupivacaine 0.5% or 7.5 mg (4 ml) hypobaric levobupivacaine 0.1875% for elective arthroscopic surgery of the knee under spinal anaesthesia. The level and duration of sensory block, intensity and duration of motor block were recorded. Unilateral sensory block was observed in 27 patients (90%) in the hyperbaric group and 24 patients (80%) in the hypobaric group in the lateral position. After 15 minutes, patients were turned to supine to redistribute the spinal block toward the non-operative side, but spinal anaesthesia was still unilateral in 18 patients (60%) in the hyperbaric group and 10 patients (33%) in the hypobaric group (P = 0.038). Time to readiness for home discharge and complete recovery of sensory block were similar in both groups. In the hyperbaric group, the motor block scores were higher on the operative side during first 10 minutes than they were in the hypobaric group (P hyperbaric group (P = 0.01). Hyperbaric and hypobaric levobupivacaine both provided satisfactory unilateral spinal anaesthesia with good haemodynamic stability for arthroscopic surgery, but with more frequent unilateral spinal anaesthesia in the hyperbaric group.

    Unilateral intracranial focal nonprogressive arteriopathy is often found in children with arterial ischemic stroke. We aimed to investigate the course of unilateral intracranial arteriopathy in young adults. We searched the Utrecht Stroke Database for patients between 16 and 50 years of age diagnosed with anterior circulation arterial ischemic stroke and a nonatherosclerotic, unilateral intracranial large-artery arteriopathy between 1991 and 2005. We assessed clinical features, potential causes, risk factors, extent of infarction and arteriopathy at presentation, long-term angiographic course, and clinical outcome. Of 356 patients with anterior circulation arterial ischemic stroke, 17 (5%) had a documented unilateral intracranial arteriopathy, of whom 14 could be included for follow-up investigations (median age, 34 years; range, 27-49 years). Median duration of follow-up was 8.8 years (range, 1.7-12.8 years). In 11 patients, onset of symptoms was not abrupt. The arteriopathy normalized completely in 5 and improved in 3 patients; in none of the patients did the arteriopathy worsen. Two of 14 patients had recurrent symptoms. Ten patients (71%) had a good outcome (modified Rankin Scale score≤2). In young adults, arterial ischemic stroke is rarely caused by a unilateral intracranial arteriopathy. Similar to children, onset of symptoms in young adults is often not abrupt and the arteriopathy may improve over time. Late recurrences were rare. Possibly, a monophasic inflammatory process, as has been suggested for childhood intracranial focal nonprogressive arteriopathies, also occurs in young adults.

    Most existing studies of a deformable ring on elastic foundation rely on the assumption of a linear foundation. These assumptions are insufficient in cases where the foundation may have a unilateral stiffness that vanishes in compression or tension such as in non-pneumatic tires and bushing bearings. This paper analyzes the in-plane dynamics of such a thick ring on a unilateral elastic foundation, specifically, on a two-parameter unilateral elastic foundation, where the stiffness of the foundation is treated as linear in the circumferential direction but unilateral (i.e. collapsible or tensionless) in the radial direction. The thick ring is modeled as an orthotropic and extensible circular Timoshenko beam. An arbitrarily distributed time-varying in-plane force is considered as the excitation. The Equations of Motion are explicitly derived and a solution method is proposed that uses an implicit Newmark scheme for the time domain solution and an iterative compensation approach to determine the unilateral zone of the foundation at each time step. The dynamic axle force transmission is also analyzed. Illustrative forced vibration responses obtained from the proposed model and solution method are compared with those obtained from a finite element model.

    In this meta-analysis, we reviewed observational studies investigating differences in intelligence quotient (IQ) scores of children with unilateral hearing loss compared to children with normal hearing. PubMed Medline, Cumulative Index to Nursing and Allied Health Literature, Embase, PsycINFO. A query identified all English-language studies related to pediatric unilateral hearing loss published between January 1980 and December 2014. Titles, abstracts, and articles were reviewed to identify observational studies reporting IQ scores. There were 261 unique titles, with 29 articles undergoing full review. Four articles were identified, which included 173 children with unilateral hearing loss and 202 children with normal hearing. Ages ranged from 6 to 18 years. Three studies were conducted in the United States and one in Mexico. All were of high quality. All studies reported full-scale IQ results; three reported verbal IQ results; and two reported performance IQ results. Children with unilateral hearing loss scored 6.3 points lower on full-scale IQ, 95% confidence interval (CI) [-9.1, -3.5], P value analysis suggests children with unilateral hearing loss have lower full-scale and performance IQ scores than children with normal hearing. There also may be disparity in verbal IQ scores. Laryngoscope, 126:746-754, 2016. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Kidney transplantation is the best available treatment for patients with end-stage renal disease. To evaluate the en bloc anastomosis technique for unilateral dual kidney transplantation (DKT). From May to October 2011, 5 patients (4 women and 1 man) with mean age of 31.8 years underwent unilateral DKT with this technique in which distal end of the aorta and proximal end of inferior vena cava (IVC) were closed with running sutures. Then, proximal end of the aorta and distal end of the IVC were anastomosed to internal (or external) iliac artery and external iliac vein, respectively. Post-operative course was uneventful. No vascular and urologic complications developed; all patient had acceptable serum creatinine at discharge time and up of 2-6 months of post-operation follow up. Unilateral DKT is a safe method for performing DKT. The proposed en bloc anastomosis can improve the outcome of the graft by reducing the cold ischemia and the operation time.

    Full Text Available Remitting seronegative symmetrical synovitis with pitting edema (RS3PE is a rare but well-reported clinical entity. It is classically described as symmetrical involvement of both upper extremities. Asymmetrical involvement had also been reported, but unilateral presentation is very rare. We hereby report a case of unilateral RS3PE in a patient of seronegative rheumatoid arthritis which was initially misdiagnosed as cellulitis and was given high dose antibiotics without any significant improvement. Later a rheumatologic consultation leads to a prompt diagnosis, and treatment with steroids leads to dramatic reversal of symptoms. This case demonstrates the rare presentation of this rare clinical entity and highlights the necessity of awareness regarding unilateral disease to clinicians.

    Unilateral parotid accumulation of radioactivity was noted in 4 elderly (80-95 years) patients after intravenous administration of /sup 67/Ga citrate. In 2 of these individuals, it was possible to carry out pertechnetate salivary gland imaging. The involved glands were functional in terms of pertechnetate accumulation, although no drainage was noted after lemon stimulation. A retrospective analysis of 72 radiogallium studies failed to show unilateral parotid uptake in any of them. However, ten cases (14%) had bilateral parotid accumulation of radiogallium. Probable causes of the bilateral parotid concentration of /sup 67/Ga were discussed. These were compared with poor oral hygiene and dehydration as possible contributing factors to unilateral parotid radiogallium concentration in the elderly.

    The mechanisms and functional anatomy underlying the early stages of speech perception are still not well understood. Auditory agnosia is a deficit of auditory object processing defined as a disability to recognize spoken languages and/or nonverbal environmental sounds and music despite adequate hearing while spontaneous speech, reading and writing are preserved. Usually, either the bilateral or unilateral temporal lobe, especially the transverse gyral lesions, are responsible for auditory agnosia. Subcortical lesions without cortical damage rarely causes auditory agnosia. We present a 73-year-old right-handed male with generalized auditory agnosia caused by a unilateral subcortical lesion. He was not able to repeat or dictate but to perform fluent and comprehensible speech. He could understand and read written words and phrases. His auditory brainstem evoked potential and audiometry were intact. This case suggested that the subcortical lesion involving unilateral acoustic radiation could cause generalized auditory agnosia.

    The charts of 100 patients who underwent anterior cervical diskectomy with fusion performed at our institution between January 1996 and February 1999 were reviewed. The incidences of hoarseness, dysphagia, and unilateral true vocal fold motion impairment were calculated. Univariate logistic regression was used to estimate the relationship of several patient and technical factors to the rates of occurrence of hoarseness and dysphagia. Patient age was found to be a significant predictor of postoperative dysphagia (p dysphagia, hoarseness, and unilateral true vocal fold motion impairment in the literature were calculated as 12.3%, 4.9%, and 1.4%, respectively. We conclude that dysphagia, hoarseness, and unilateral vocal fold motion impairment continue to remain significant complications of anterior cervical diskectomy with fusion. Older patients may be at higher risk for dysphagia.

    Unilateral vocal fold paralysis resulting in glottic incompetence can cause impairment of laryngeal functions, including airway protection and phonation. The objective of this study is to present an easy new technique for harvesting and injection of abdominal fat into the vocal fold for patients with unilateral vocal fold paralysis. This is a retrospective study of patients carried out on 16 patients suffering from unilateral vocal fold paralysis resulting from different etiologies. All patients were subjected to the protocol of voice assessment pre- and postoperatively. All patients were subjected to fat injection of the paralyzed vocal fold. There was a statistically significant difference between the pre- and postoperative grade of voice parameters. Vocal fold injection using fat medializes a paralyzed vocal fold by increasing vocal fold volume. Fat injections are safe and easily mastered; and in the absence of the standard settings for fat harvesting and injection, it could be performed with minimal equipment that are readily available in any operating room.

    2017-06-01

    Full Text Available Unilateral laterothoracic exanthem (ULE, or asymmetric periflexural exanthem of childhood (APEC, is an uncommon skin eruption that usually occurs in childhood, with unilateral distribution and self limiting course. The etiology of ULE is unknown, but viral cause is suspected. We report a case of ULE in a 4-year-old girl, that was associated with parvo virus B19 infection, and a brief selected literature review. The patient presented with unilateral maculopapular rash on the left side of the body which was asymptomatic and resolved spontaneously within 5 weeks. The clinical diagnosis of ULE may be precise, ruling out a broad spectrum of differential diagnosis, and prevent unnecessary examinations, whereas the patient is informed about the benign self-limiting nature of ULE.

    Unilateral spatial neglect (USN) is characterized by the inability to report or respond to people or objects presented on the side contralateral to the lesioned side of the brain and has been associated with poor functional outcomes and long stays in hospitals and rehabilitation centers. Pharmacological interventions (medical interventions only, use of drugs to improve the health condition), such as dopamine and noradrenergic agonists or pro-cholinergic treatment, have been used in people affected by USN after stroke, and effects of these treatments could provide new insights for health professionals and policy makers. To evaluate the effectiveness and safety of pharmacological interventions for USN after stroke. We searched the Cochrane Stroke Group Trials Register (April 2015), the Cochrane Central Register of Controlled Trials (April 2015), MEDLINE (1946 to April 2015), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to April 2015), EMBASE (1980 to April 2015), PsycINFO (1806 to April 2015) and Latin American Caribbean Health Sciences Literature (LILACS) (1982 to April 2015). We also searched trials and research registers, screened reference lists, and contacted study authors and pharmaceutical companies (April 2015). We included randomized controlled trials (RCTs) and quasi-randomized controlled trials (quasi-RCTs) of pharmacological interventions for USN after stroke. Two review authors independently assessed risk of bias in the included studies and extracted data. We included in the review two studies with a total of 30 randomly assigned participants. We rated the quality of the evidence as very low as the result of study limitations, small numbers of events, and small sample sizes, with imprecision in the confidence interval (CI). We were not able to perform meta-analysis because of heterogeneity related to the different interventions evaluated between included studies. Very low-quality evidence from one trial (20 participants

    2017-10-01

    Objective Unilateral hearing loss has been shown to have negative consequences for speech and language development in children. The objective of this study was to systematically review the current literature to quantify the impact of unilateral hearing loss on children, with the use of objective measures of speech and language. Data Sources PubMed, EMBASE, Medline, CINAHL, and Cochrane Library were searched from inception to March 2015. Manual searches of references were also completed. Review Methods All studies that described speech and language outcomes for children with unilateral hearing loss were included. Outcome measures included results from any test of speech and language that evaluated or had age-standardized norms. Due to heterogeneity of the data, quantitative analysis could not be completed. Qualitative analysis was performed on the included studies. Two independent evaluators reviewed each abstract and article. Results A total of 429 studies were identified; 13 met inclusion criteria and were reviewed. Overall, 7 studies showed poorer scores on various speech and language tests, with effects more pronounced for children with severe to profound hearing loss. Four studies did not demonstrate any difference in testing results between patients with unilateral hearing loss and those with normal hearing. Two studies that evaluated effects on speech and language longitudinally showed initial speech problems, with improvement in scores over time. Conclusions There are inconsistent data regarding effects of unilateral hearing loss on speech and language outcomes for children. The majority of recent studies suggest poorer speech and language testing results, especially for patients with severe to profound unilateral hearing loss.

    Purpose The purpose of the present study was to perform a pattern analysis in patients with temporomandibular disorder (TMD) resulting from unilateral mastication due to chronic periodontitis. Methods Thirty participants with signs or symptoms of TMD who engaged in unilateral mastication due to periodontitis-related discomfort (test group) were selected. Another 30 subjects exhibiting signs or symptoms of TMD resulting from unilateral mastication not due to chronic periodontitis (control group) were also recruited. An interview-based questionnaire was administered, and an examination of the temporomandibular joint (TMJ) with determination of periodontal status was performed. Results The duration of unilateral mastication was significantly longer in the control group than in the test group. There was a significant negative correlation between the duration of unilateral mastication and the Community Periodontal Index score. Using the Research Diagnostic Criteria for TMD (RDC/TMD) axis I algorithms, all the subjects were assigned to 3 main groups. The test group exhibited significantly a higher diagnostic distribution of group III (arthralgia, osteoarthritis, or osteoarthrosis), and in both the test and control groups, the number of diagnoses was larger for the non-chewing side. The control group showed a significantly higher diagnostic distribution of group I (myofacial pain), and in both the test and control groups, the number of diagnoses was larger for the chewing side. Conclusions The results of the present study indicate that unilateral mastication due to chronic periodontitis could induce not only pain but also structural TMJ changes if adequate treatment is not administered and supported within a short time from the onset of the condition. Therefore, immediate treatment of chronic periodontitis is recommended to prevent not only the primary progress of periodontal disease, but also secondary TMJ-related problems. Furthermore, subjects who have suffered chronic

    Unilateral spinal anesthesia has its advantages, especially in patients undergoing outpatient basis surgeries. Low dose, slow speed of administration, and the lateral positioning make easier the unilateral distribution in spinal anesthesia. Isobaric, hyperbaric, and hypobaric solutions of bupivacaine were compared in the unilateral spinal anesthesia in patients undergoing outpatient basis orthopedic surgeries. One hundred and fifty patients were randomly divided in three groups to receive 5 mg of 0.5% isobaric bupivacaine (Iso Group), 5 mg of 0.5% hyperbaric bupivacaine (Hyper Group), or 5 mg of 0.15% hypobaric bupivacaine (Hypo Group). The solutions were administered in the L3-L4 space with the patient in the lateral decubitus and remaining in this position for 20 minutes. Sensitive anesthesia was evaluated by the pin prick test. Motor blockade was determined by the modified Bromage scale. Both blockades were compared with the opposite side and among themselves. There was a significant difference between the side of the surgery and the opposite side in all three groups at 20 minutes, but the frequency of unilateral spinal anesthesia was greater with the hyperbaric and hypobaric solutions. Sensitive and motor blockades were observed in 14 patients in the Iso Group, 38 patients in the Hyper Group, and 40 patients in the Hypo Group. Patients did not develop any hemodynamic changes. Postpuncture headache and transitory neurological symptoms were not observed. Spinal anesthesia with hypobaric and hyperbaric solutions present a higher frequency of unilateral anesthesia. After 20 minutes, isobaric bupivacaine mobilized into cerebrospinal fluid (CSF) resulted in unilateral spinal anesthesia in only 28% of the patients.

    The aim of this study was to quantify grey matter changes in children with unilateral cerebral palsy (UCP), differentiating between cortical or deep grey matter (CDGM) lesions, periventricular white matter (PWM) lesions, and unilateral and bilateral lesions. In a cross-sectional study we obtained high resolution structural magnetic resonance images from 72 children (41 males, 31 females, mean age 10y 9mo [SD 3y 1mo], range 5y 1mo-17y 1mo) with UCP (33 left, 39 right hemiplegia; Manual Ability Classification System level I n=29, II n=43; Gross Motor Function Classification System level I n=46, II n=26), and 19 children with typical development (CTD; eight males, 11 females, mean age 11y 2mo [SD 2y 7mo], range 7y 8mo-16y 4mo). Images were classified by lesion type and analyzed using voxel-based morphometry (VBM) and subcortical volumetric analysis. Deep grey matter volumes were not significantly different between children with CDGM and PWM lesions, with the thalamus, putamen, and globus pallidus being reduced unilaterally in both groups compared with CTD (p≤0.001). Children with CDGM lesions additionally showed widespread cortical changes involving all lobes using VBM (p<0.01). Children with bilateral lesions had reduced thalamus and putamen volumes bilaterally (p<0.001). The thalamic volume was reduced bilaterally in children with unilateral lesions (p=0.004). Lesions to the PWM cause secondary changes to the deep grey matter structures similar to primary changes seen in CDGM lesions. Despite having a unilateral phenotype, grey matter changes are observed bilaterally, even in children with unilateral lesions. © 2014 Mac Keith Press.

    The objective of our study was to retrospectively compare the radiography and MRI findings of unilateral spondylolysis in the upper lumbar segment and in the lower lumbar segment and to consider how these radiologic findings can be applied in the diagnosis of unilateral spondylolysis. Thirty patients with unilateral lumbar spondylolysis were categorized into one of two groups according to the lumbar levels involved with pars interarticularis defects: group A (L1, L2, and L3) or group B (L4 and L5). On radiographs, we evaluated contour bulging of the affected pars interarticularis, reactive sclerosis in the contralateral pedicle, anterolisthesis of the involved vertebra, and deviation of the spinous process. On MRI, we assessed pseudoarticulation of the pars interarticularis defect, uneven distribution of posterior epidural fat, the interspinous distance between adjacent segments, facet and disk degeneration in adjacent segments, and other anomalous changes. Among the 63 patients with unilateral spondylolysis, the upper lumbar segment was involved in 29 and the lower lumbar segment, in 34. Group A often displayed contour bulging of the affected pars interarticularis, reactive sclerosis of the contralateral pedicle, and contralateral deviation of the spinous process, all of which were easily detectable on radiography. Group B frequently showed anterolisthesis, pseudoarticulation of the pars interarticularis defect, adjacent facet-disk degeneration, and other anomalous changes that were well observed on MRI. Unilateral lumbar spondylolysis displayed radiologic differences in morphology of the isthmic defect itself and in ancillary findings of the adjacent structures based on the segment involved. Recognition of different ancillary features of unilateral spondylolysis with the use of a feasible diagnostic tool can be helpful for the diagnosis of cases in which a direct sign of isthmic defect is equivocal.

    Purpura annularis telangiectodes (PAT), also known as Majocchi purpura, is a rare form of pigmented purpuric dermatosis characterized by non-palpable red-brown, occasionally pruritic patches which progress to hyperpigmented halos. Purpura annularis telangiectodes usually presents in female adolescents as benign symmetric lesions with a predilection for the lower extremities. We present an atypical case of unilateral PAT in an elderly male. To our knowledge, our patient at 85-years-old is the oldest PAT and first unilateral purpura annularis telangiectodes case described in the literature.

    Full Text Available Partial unilateral lentiginosis is an unusual pigmentary disorder characterized by numerous lentigines grouped within an area of normal skin. Pigmented macules are usually localized in one half of the body. Associations with café-au-lait spots, cutis marmorata, acanthosis nigricans, nevus depigmentosus, vitiligo, blue nevus, segmental neurofibromatosis, central nervous system diseases, celiac disease, and sickle cell anemia have been reported. We describe a 17-year-old male patient with a partial unilateral lentiginous lesion on the left side of the body and left upper back and incidental polyp in the descending colon.

    A 7-year-old male miniature schnauzer dog with unilateral cryptorchidism was presented for elective orchiectomy. Surgery to remove the cryptorchid testis revealed a fully formed uterus with horns attached to both testis and the body and cervix terminating at the prostate gland. The gross and microscopic diagnosis for the genital tract was persistent Müllerian duct syndrome with unilateral cryptorchidism. Additional associated lesions included cystic endometrial hyperplasia and a solitary, intratubular seminoma within the undescended testis. Persistent Müllerian duct syndrome is rare among domestic animals but is more common in miniature schnauzer dogs because of inheritance as an autosomal recessive trait.

    Full Text Available Adrenal hemorrhage following blunt abdominal trauma is extremely rare. Most of the lesions are unilateral and right sided. Although often asymptomatic, life-threatening adrenal insufficiency may develop in the bilateral adrenal gland hemorrhage. Isolated adrenal injuries are very rare. They are often associated with other organ injuries. The mortality rates of patients range from 7% to 32%. In this report, we present the computed tomography and magnetic resonance imaging findings of unilateral adrenal hemorrhages in two patients with a history of fall from a height.

    Full Text Available Ultrasound-guided peripheral nerve blocks facilitate ambulatory anesthesia for upper limb surgeries. Unilateral phrenic nerve blockade is a common complication after interscalene brachial plexus block, rather than the supraclavicular block. We report a case of severe respiratory distress and bilateral bronchospasm following ultrasound-guided supraclavicular brachial plexus block. Patient did not have clinical features of pneumothorax or drug allergy and was managed with oxygen therapy and salbutamol nebulization. Chest X-ray revealed elevated right hemidiaphragm confirming unilateral phrenic nerve paresis.

    A solitary patient with symptoms similar to those of shortlasting unilateral neuralgiform conjunctival injection and tearing (SUNCT) was first mentioned in 1978. The term SUNCT was first used in 1991. SUNCT is an acronym; the “S” signifies “Shortlasting”; the “U” symbolizes “Unilateral”; “N” stands for “Neuralgiform”; the “C” for “Conjunctival injection”; and “T” for “Tearing.” The term short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms were marketed in 2004. The terminology and new view points are discussed and nosography proposal for SUNCT is presented. PMID:29740387

    1996-12-20

    In the present study a modern high resolution electroencephalography (EEG) technique was used to investigate the dynamic functional topography of human cortical activity related to simple unilateral internally triggered finger movements. The sensorimotor area (M1-S1) contralateral to the movement as well as the supplementary motor area (SMA) and to a lesser extent the ipsilateral M1-S1 were active during the preparation and execution of these movements. These findings suggest that both hemispheres may cooperate in both planning and production of simple unilateral volitional acts.

    Unilateral breast edema has many causes, though among these, congestive heart failure is rare. We report mammographic and sonographic findings of unilateral breast edema due to congestive heart failure. Mammography showed diffuse increase density and skin thickening but no evidence of mass or calcification. Ultrasonography showed skin thickening and increased echogenicity in the subcutaneous fat layer, while in the dermal layer, with tubular and reticular anechoic structures suggestive of dilated lymphatics were seen. After treatment of the heart failure, resolution of the abnormalities seen on mammogram established that these were secondary findings.

    Ribeiro, Phillip; Patel, Swetal; Qazi, Rizwan A

    2016-05-07

    Central venous stenosis is a well-known complication in patients with vascular access for hemodialysis. We report two cases involving patients on hemodialysis with arteriovenous fistulas who developed reversible unilateral conductive hearing loss secondary to critical stenosis of central veins draining the arteriovenous dialysis access. A proposed mechanism for the patients' reversible unilateral hearing loss is pterygoid venous plexus congestion leading to decreased Eustachian tube patency. Endovascular therapy was conducted to treat the stenosis and the hearing loss of both patients was returned to near normal after successful central venous angioplasty.

    Full Text Available Se expone una variante de abordaje al surco ciliar para la fijación del lente intraocular de cámara posterior, que está a nuestro alcance, en pacientes en que no existe soporte capsular o este es insuficiente. Se describe la técnica. Se realizó en 17 pacientes de los que se obtuvo mejoría visual en todos los casos (20/50-20/20 con un seguimiento promedio de 12 meses. Esta variante tiene la ventaja de evitar el paso de la aguja por el surco ciliar a ciegas, pues se utiliza el abordaje a través de la esclera y con ello evitamos dañar estructuras oculares aledañas evitando el riesgo de complicaciones por lo que se logra la recuperación anatómica y funcional en todos los casos.A variant to approach the ciliary sulcus for fixating the posterior chamber intraocular lens, which is within our reach, in patients with insufficient or no capsular support, is explained. The technique is described here and it was applied to 17 patients. Visual improvement was obtained in all cases (20/50-20/20 with an average follow-up of 12 months. This variant allows to prevent the blind passage of the needle through the ciliary sulcus, since it is approached via the sclera, avoiding to damage adjoining ocular structures and to have complications, and making possible the anatomic and functional recovery of all patients.

  16. Craniofacial morphology of children with complete unilateral cleft lip and palate following labioplasty and palatoplasty

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Background: A complete unilateral cleft lip and palate generally results in asymmetry of the midface. The lack of continuity in the perilabial musculature through the midline contributes to a malpositioning of the underlying osseus structures which are often underdeveloped. Purpose: The purpose of this study was to determine whether there are differences in the craniofacial morphology among children with complete unilateral cleft lip and palate following labioplasty and palatoplasty as compared with children without cleft lip and palate at the same pubertal age. Methods: A series of 14 consecutively treated subjects with complete unilateral cleft lip and palate following labioplasty and palatoplasty were compared with 14 pubertal stage-matched controls with normal craniofacial structure. Pubertal stage was determined with cervical vertebral maturation (CVM method improved by Baccetti et al, 2002. Lateral cephalograms were used for comparison. An unpaired t-test was run for 14 subjects with complete unilateral cleft lip and palate and 14 normal subjects. Results: There were significant cephalometric differences in anterior cranial base length (p = .002, cranial base length (p = .001, maxillary length (p = .000, mandibular length (p = .000, mandibular ramus height (p = .000, mandibular body length (p = .002, and upper anterior face height (p = .004. There was no significant cephalometric difference in posterior cranial base length (p = .051, lower anterior face height (p = .206, posterior face height (p = .865, growth pattern/ facial type (p = .202. Conclusion: There were craniofacial morphology differences between children with complete unilateral cleft lip and palate post labioplasty and palatoplasty and children without cleft lip and palate at the age of pubertal. Children with complete unilateral cleft lip and palate post labioplasty and palatoplasty had shorter length of the anterior cranial base, cranial base, maxilla, mandible, mandibular

  17. Spatial Release From Masking in Children: Effects of Simulated Unilateral Hearing Loss.

    Science.gov (United States)

    Corbin, Nicole E; Buss, Emily; Leibold, Lori J

    The purpose of this study was twofold: (1) to determine the effect of an acute simulated unilateral hearing loss on children's spatial release from masking in two-talker speech and speech-shaped noise, and (2) to develop a procedure to be used in future studies that will assess spatial release from masking in children who have permanent unilateral hearing loss. There were three main predictions. First, spatial release from masking was expected to be larger in two-talker speech than in speech-shaped noise. Second, simulated unilateral hearing loss was expected to worsen performance in all listening conditions, but particularly in the spatially separated two-talker speech masker. Third, spatial release from masking was expected to be smaller for children than for adults in the two-talker masker. Participants were 12 children (8.7 to 10.9 years) and 11 adults (18.5 to 30.4 years) with normal bilateral hearing. Thresholds for 50%-correct recognition of Bamford-Kowal-Bench sentences were measured adaptively in continuous two-talker speech or speech-shaped noise. Target sentences were always presented from a loudspeaker at 0° azimuth. The masker stimulus was either co-located with the target or spatially separated to +90° or -90° azimuth. Spatial release from masking was quantified as the difference between thresholds obtained when the target and masker were co-located and thresholds obtained when the masker was presented from +90° or -90° azimuth. Testing was completed both with and without a moderate simulated unilateral hearing loss, created with a foam earplug and supra-aural earmuff. A repeated-measures design was used to compare performance between children and adults, and performance in the no-plug and simulated-unilateral-hearing-loss conditions. All listeners benefited from spatial separation of target and masker stimuli on the azimuth plane in the no-plug listening conditions; this benefit was larger in two-talker speech than in speech-shaped noise.

    Unilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) in patients with Parkinson's disease improves skeletomotor function assessed clinically, and bilateral STN DBS improves motor function to a significantly greater extent. It is unknown whether unilateral STN DBS improves oculomotor function and whether bilateral STN DBS improves it to a greater extent. Further, it has also been shown that bilateral, but not unilateral, STN DBS is associated with some impaired cognitive-motor functions. The current study compared the effect of unilateral and bilateral STN DBS on sensorimotor and cognitive aspects of oculomotor control. Patients performed prosaccade and antisaccade tasks during no stimulation, unilateral stimulation, and bilateral stimulation. There were three sets of findings. First, for the prosaccade task, unilateral STN DBS had no effect on prosaccade latency and it reduced prosaccade gain; bilateral STN DBS reduced prosaccade latency and increased prosaccade gain. Second, for the antisaccade task, neither unilateral nor bilateral stimulation had an effect on antisaccade latency, unilateral STN DBS increased antisaccade gain, and bilateral STN DBS increased antisaccade gain to a greater extent. Third, bilateral STN DBS induced an increase in prosaccade errors in the antisaccade task. These findings suggest that while bilateral STN DBS benefits spatiotemporal aspects of oculomotor control, it may not be as beneficial for more complex cognitive aspects of oculomotor control. Our findings are discussed considering the strategic role the STN plays in modulating information in the basal ganglia oculomotor circuit.

    Full Text Available Resumen: Presentamos un nuevo abordaje mínimamente invasivo mediante distracción intraoral de rama mandibular bilateral (bilateral internal ramus distraction para el tratamiento del síndrome de apnea obstructiva del sueño en el paciente adulto. Tras la planificación virtual 3 D, el paciente es intervenido bajo anestesia general y asistencia endoscópica, dentro de un protocolo de cirugía mayor ambulatoria, y es dado de alta el mismo día de la cirugía. Tras un periodo de 5 días, la rama mandibular se alarga verticalmente durante un periodo que oscila entre 10 y 50 días, a un ritmo de 0,5 a 1 mm diario, hasta que el índice de apnea hipopnea alcanza una cifra inferior a 5 pausas por hora (nivel de curación o el resalte negativo dentario (overjet se sitúa en valores que ya superan los 10 mm.La titulación del procedimiento mediante parámetros clínicos, poligráficos o polisomnográficos permite al cirujano personalizar el avance mandibular en cada caso. Tras un alargamiento que suele oscilar entre 10 y 25 mm, los distractores se mantienen durante 6 meses hasta que concluye el periodo de consolidación. La indicación de cirugía maxilar tras el avance mandibular se realizará en dependencia del índice de apnea hipopnea residual, de la oclusión y del análisis facial.La distracción intraoral de rama mandibular bilateral es una técnica altamente efectiva para la curación del síndrome de apnea obstructiva del sueño en pacientes adultos con o sin retrognatia, y podría estar indicada incluso en pacientes con morbilidades asociadas, como enfermedades cardiovasculares graves u obesidad mórbida, en los que un procedimiento quirúrgico de mayor envergadura, como el avance maxilomandibular clásico, se descarta como alternativa quirúrgica.

    Anterior uveitis is the most common form of intraocular inflammation. The main aim of this study was to determine the viral etiology in patients with unilateral cases of anterior uveitis. A total of 12 consecutive patients with the diagnosis of idiopathic unilateral anterior uveitis were included prospectively. Aqueous specimens were obtained from each patient by anterior chamber paracentesis and subjected to the detection of viral DNA/RNA genome by polymerase chain reaction assay for herpes simplex virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, and rubella virus. There were six male and six female patients. The mean age was 43 years, with an age range of 11-82 years. All 12 cases presented with unilateral anterior uveitis. In four (33%) patients, polymerase chain reaction was positive for viral genome. Two patients were positive for herpes simplex virus type 1, one patient was positive for cytomegalovirus and one for Epstein-Barr virus. Recent molecular diagnostic assays would help in the identification of the causative agent in patients with unilateral anterior uveitis.

    Full Text Available Patients with unilateral cerebral palsy (CP often have impaired movement coordination, reduced between-limb synchronization, and less weight bearing on the affected side, which can affect the maintenance of an upright weight-bearing position and gait. This study evaluated whether the different postural patterns of children with unilateral CP could be statistically recognized using cluster analysis. Forty-five outpatients with unilateral CP (mean age, 9 years and 5 months and 51 able-bodied children with mild scoliosis (mean age, 9 years and 2 months were included. One observer performed moiré topography (MT examinations using a CQ Electronic System (Poland device. A weight distribution analysis on the base of support (BOS between the body sides was performed simultaneously. A force plate dynamographic platform (PDM, ZEBRIS (Germany, with FootPrint software was used for these measurements. Cluster analysis revealed three groups: Cluster 1 (, 73.96%, Cluster 2 (, 8.33%, and Cluster 3 (, 17.71%. Based on the MT parameters (extracted using a data reduction technique, three typical asymmetrical postural patterns were described: (1 the postural pattern of children with mild scoliosis (SCOL, (2 the progravitational postural pattern (PGPP, and (3 the antigravitational pattern. Patterns two and three were identified in children with unilateral CP.

    Unilateral treatment with sustained release IGF-1 to one medial rectus muscle in infant monkeys was performed to test the hypothesis that strabismus would develop as a result of changes in extraocular muscles during the critical period of development of binocularity. Sustained release IGF-1 pellets were implanted unilaterally on one medial rectus muscle in normal infant monkeys during the first 2 weeks of life. Eye position was monitored using standard photographic methods. After 3 months of treatment, myofiber and neuromuscular size, myosin composition, and innervation density were quantified in all rectus muscles and compared to those in age-matched controls. Sustained unilateral IGF-1 treatments resulted in strabismus for all treated subjects; 3 of the 4 subjects had a clinically significant strabismus of more than 10°. Both the treated medial rectus and the untreated ipsilateral antagonist lateral rectus muscles had significantly larger myofibers. No adaptation in myofiber size occurred in the contralateral functionally yoked lateral rectus or in myosin composition, neuromuscular junction size, or nerve density. Sustained unilateral IGF-1 treatment to extraocular muscles during the sensitive period of development of orthotropic eye alignment and binocularity was sufficient to disturb ocular motor development, resulting in strabismus in infant monkeys. This could be due to altering fusion of gaze during the early sensitive period. Serial measurements of eye alignment suggested the IGF-1-treated infants received insufficient coordinated binocular experience, preventing the establishment of normal eye alignment. Our results uniquely suggest that abnormal signaling by the extraocular muscles may be a cause of strabismus.

    Full Text Available This paper shows the existence of a solution of the quasi-static unilateral contact problem with nonlocal friction law for nonlinear elastic materials. We set up a variational incremental problem which admits a solution, when the friction coefficient is small enough, and then by passing to the limit with respect to time we obtain a solution.

    Facial appearance and speech outcome may affect psychosocial functioning in girls and boys. Several studies reported dissatisfaction with facial appearance and more specifically the lip and mouth profile in children with cleft lip and palate (CLP). The purpose of this controlled study was to measure the tongue and lip strength and endurance in boys and girls with CLP. Twenty-five subjects (mean age: 10.6 years) with a unilateral CLP and a gender- and age- matched control group were selected. All subjects with an unilateral CLP consulted the same craniofacial team and had undergone an identical surgical procedure. Surgical procedure of the lip was performed using a modified Millard technique without primary nose correction at an average age of 5.5 months. The Iowa Oral Performance instrument was used to measure lip and tongue strength and tongue endurance. The results of the Iowa Oral Performance measurement showed no significant differences between the subjects with an unilateral cleft lip and palate and the age and gender matched control group without a cleft lip and palate. There is no significant differences regarding oral strength more specifically the lip and tongue strength and endurance between subjects with and without an unilateral cleft lip and palate. ENT specialists and speech pathologists must be aware of this aspect of the normal lip and tongue functions. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Conclusions: Tibial lengthening may effectively correct gait and satisfactorily improve body image in young patients with unilateral Crowe type-IV DDH. Mono-lateral external fixator allows for accelerated postoperative rehabilitation and optimal preservation of ankle movements. Lengthening along with intramedullary nails may significantly reduce the external fixation time and the risk of fixator-related complications.

    Full Text Available Unilateral pulmonary edema of the dependant lung was observed in three patients during laparoscopic donor nephrectomy. Patients were treated with 02 supplementation by face mask, fluid restriction and diuretic. All the patients were relieved of symptoms with radiological improvement. The possible causes of this unusual complication following laparoscopic surgery appear to be prolonged lateral decubitus position and high intraoperative fluid infusion.
