    Full Text Available Hacemos un estudio anátomo-funcional de la arteria cerebral anterior recalcando la importancia que tiene la ligadura de esta arteria. Sintetizamos la patogenia de los aneurismas en cuatro hechos fundamentales: los aneurismas vestigiales originados en brotes vasculares no desarrollados o que no han involucionado normalmente; la falta de desarrollo de la túnica elástica en la zona de bifurcación de los grandes vasos; la arterioesclerosis; los procesos inflamatorios de la túnica media (sífilis y micosis. Hacemos un estudio clínico de los aneurismas del complejo cerebral-comunicante anterior, llamando la atención sobre aquellos en los que, a las hemorragias subaracnoidales, se asocian manifestaciones en el fondo de ojo, trastornos psíquicos y fenómenos motores. Llamamos la atención sobre las formas pseudo-tumorales quiasmáticas y los denominados aneurismas trombosantes que originan el síndrome progresivo fronto-cíngulo-calloso. Estudiamos la radiología simple de los aneurismas de esta región, llamando la atención sobre las calcificaciones cirsoideas suprasellares y los fenómenos de erosión de la silla turca. Llamamos la atención sobre la importancia de la arteriografía para confirmar el diagnóstico, estudiar la circulación colateral, el tamaño, la forma y el pedículo del aneurisma, elementos fundamentales para el plan operatório. En el tratamiento quirúrgico descartamos, por ineficaz, la ligadura de la carótida interna en el cuello. Es fundamental el abordaje intracraneano por vía subfrontal en los aneurismas de la porción précomunicante y comunicante con desarrollo hacia abajo, mientras que, la via sagital-frontal se utilizará en los aneurismas de desarrollo hacia arriba ya sea de la comunicante o de la porción distal de la arteria cerebral anterior o sus ramas. Insistimos sobre un hecho muy importante cual es la anestesia y, en especial, el uso de la hipotensión controlada, insistiendo de que la tensión se

    Full Text Available La enfermedad de Kawasaki se caracteriza por una vasculitis generalizada, de singular gravedad cuando afecta las arterias coronarías, lo cual ocurre hasta en el 40 % de los casos no tratados. El tratamiento combinado de aspirina con gammaglobulina intravenosa precoz y a altas dosis ha conseguido disminuir la incidencia de la patología coronaría. A continuación se presenta el caso de una niña de 9 años de edad, con cuadro clínico de enfermedad de Kawasaki complicada con un aneurisma sacular gigante de la arteria coronaría izquierda. Los hallazgos ecocardiográficos y angiográficos se analizan y se revisa la literatura al respecto.

    Full Text Available La angina de pecho es un síntoma frecuente en pacientes con hipertensión pulmonar (HP de cualquier etiología. Aunque su fisiopatología no está aclarada, las causas propuestas son: la isquemia subendocárdica por aumento del estrés parietal del ventrículo derecho, la dilatación de la arteria pulmonar por incrementos transitorios de la presión pulmonar y la compresión extrínseca del tronco de la arteria coronaria izquierda (TCI por la arteria pulmonar (AP dilatada. Se presentan tres casos que muestran la relación entre la angina de pecho y la compresión del TCI en pacientes con HP asociada a cardiopatías congénitas, tratados mediante implante de stent coronario.

    Full Text Available La verdadera prevalencia del síndrome de atrapamiento de la arteria poplítea es desconocida; se estima en un 0.16%. Se considera la principal causa de claudicación intermitente en jóvenes deportistas sin factores de riesgo cardiovasculares. Se caracteriza por la compresión extrínseca de la arteria poplítea, ya sea por defecto anatómico de las estructuras músculo-tendinosas o por hipertrofia de los músculos gemelos, lo cual ocasiona el atrapamiento y síntomas de parestesias, frialdad y claudicación intermitente en la extremidad comprometida. La compresión crónica de la arteria puede llevar a daño irreversible con formación de trombos y aneurismas y a la consiguiente amputación de la extremidad, por lo que el diagnóstico y el tratamiento oportunos son de gran importancia para el paciente.The true prevalence of the popliteal artery entrapment syndrome is unknown, it is estimated to be 0.16%. It is considered as the main cause of intermittent claudication in young athletes without cardiovascular risk factors. It is characterized by the extrinsic compression of the popliteal artery either caused by defects of the muscle-tendon structures or by the hypertrophy of the gastrocnemius muscle leading to the arterial entrapment and symptoms of paresthesia, intermittent claudication and coldness of the affected limb. Chronic compression of the artery may lead to irreversible damage with formation of thrombi and aneurysms and the subsequent amputation of the limb. Therefore, correct diagnosis and treatment are of great importance for the patient.

  5. Rupture of hepatic artery aneurysm associated with ischemic hepatitis Rotura de arteria hepática aneurismática asociada con hepatitis isquémica

    Full Text Available Hepatic artery aneurysms are scarcely reported, mainly because of non-specific symptoms. More often, they are incidental findings during imaging studies to investigate other acute or chronic abdominal conditions. These aneurysms are usually detected in the sixth decade of life, predominantly among males. We report the case of a 69 year-old female with an unsuspected huge hepatic artery aneurysm associated with ischemic hepatitis. Suspicion of aneurysm arose during imaging studies to clarify the origin of jaundice and abdominal pain. After establishment of the diagnosis, but before open surgery, there was a spontaneous rupture of the aneurysm, which caused hemoperitoneum and death. The necropsy study confirmed ischemic hepatitis. Hepatic artery aneurysms are second among the visceral aneurysms, and may cause abdominal pain, jaundice, and hemorrhagic events. One should suspect abdominal aneurysms in elderly patients with unclear abdominal pain, and this hypothesis should be ruled out by imaging studies.La publicación de trabajos sobre aneurismas en la arteria hepática es escasa, debido a los síntomas no específicos y a que constituyen hallazgos incidentales durante investigación de otras condiciones abdominales agudas o crónicas. Estos aneurismas son más frecuentes en varones y en la sexta década de la vida. Presentamos el caso de una mujer de 69 años de edad que ingresa en el hospital con un aneurisma de arteria hepática no sospechado previamente, asociado con hepatitis isquémica. La sospecha de aneurisma empezó durante estudio de imágenes para aclaramiento del origen de ictericia y dolor abdominal. Después de confirmado el diagnóstico, pero antes de la operación planeada, ocurrió rotura espontánea del aneurisma causando hemoperitoneo y muerte. El estudio de necropsia confirmó hepatitis isquémica. Los aneurismas de la arteria hepática son los segundos entre los aneurismas viscerales y pueden causar dolor abdominal, ictericia

    Full Text Available Existen numerosos casos comunicados sobre la disfunción ventricular izquierda reversibleprecipitada por estrés emocional, pero su mecanismo no se conoce. En esta presentación sedescribe la evaluación de dos pacientes que consultaron con un cuadro clínico típico desíndrome de Tako-Tsubo, dolor precordial luego de un estrés emocional, disfunción ventricularizquierda transitoria y arterias coronarias angiográficamente normales. Con el objetivo deprofundizar el conocimiento de las arterias coronarias y la fisiopatología de esta enfermedad,a ambas se les realizó una tomografía multislice, en la que se evidenciaron lesionescoronarias similares a las halladas en accidentes de placa responsables de síndromescoronarios agudos. Si bien estos hallazgos deben completarse con estudios posteriores conun número mayor de pacientes, sugieren que al menos un subgrupo de pacientes con síndromede Tako-Tsubo tiene un sustrato fisiopatológico similar a los síndromes coronariosagudos.REV ARGENT CARDIOL 2009;77:227-230.

    2015-03-01

    Full Text Available Tanto en el ámbito civil como en el militar, las lesiones vasculares de las extremidades inferiores son frecuentes y potencialmente mortales. Las medidas de soporte iniciales para combatir el shock, una actitud quirúrgica técnicamente correcta encaminada a reparar precozmente la vascularización del miembro y un control postoperatorio estricto y continuo son los pilares básicos del tratamiento. En condiciones óptimas, las tasas de amputación y de mortalidad se hallan por debajo del 10 y del 4%, respectivamente. Presentamos a continuación un caso de un militar afgano con una lesión con pérdida de substancia de la arteria femoral en el que se consiguió una revascularización inicial con un shunt temporal. Tras ser estabilizado y evacuado al ROLE 2 de Herat, se realizó un injerto autólogo de la vena safena contralateral.

    Full Text Available Objetivo: Determinar las características anatómicas de las arterias coronarias del cerdo, mediante inyección con látex. Materiales y métodos: Se usaron 100 corazones de cerdo. Se insertaron sondas Nelaton a través de las arterias coronarias y se les inyectó solución de látex y tinta china. Se determinó el diámetro y el punto de origen para la coronaria derecha, coronaria izquierda, interventricular paraconal y circunfleja. Se cuantificaron el número de ramas diagonales, marginales ventriculares izquierdas y postero laterales. Se determinó frecuencia de ramus intermedius y tipo de dominancia. Se realizó análisis estadístico con un error estándar del 5%, con el Epidat 3,1. Resultados: El 100% de los orígenes anatómicos de las arterias coronarias fueron normales. La dominancia mas frecuente fue la derecha, 73%. El promedio de número de ramas marginales izquierdas, diagonales y posterolaterales fue de 3. La frecuencia de ramus intermedius fue de 12%. El calculo de chi cuadrado de Pearson mostró significancia entre el ramus intermedius y número de ramas marginales izquierdas (p=0,0009. Conclusiones: Las características anatómicas de las arterias coronarias del cerdo son similares a las del humano. El ramus intermedius se comporta como una primera rama marginal izquierda y no como una primera rama diagonal como lo afirman algunos autores.

    Antecedentes: la arteria cerebral anterior se origina de la bifurcación de la arteria carótida interna lateral al quiasma óptico, posteriormente se une con su homóloga contralateral mediante la arteria comunicante anterior. El complejo precomunicante(A1)-arteria comunicante anterior es el lugar más frecuente de variantes anatómicas y el sitio con mayor cantidad de aneurismas (30 a 37%). Objetivo: conocer la anatomía microquirúrgica, las variantes anatómicas y la importancia del complejo segmento precomunicante-arteria comunicante anterior en cirugía neurológica de la patología vascular, principalmente aneurismas, en población mexicana. Material y métodos: estudio prospectivo y descriptivo efectuado en el Departamento de Anatomía de la Facultad de Medicina (UNAM) en 30 encéfalos inyectados. Se estudió la anatomía microquirúrgica (longitud y calibre) del complejo segmento precomunicante-arteria comunicante anterior de la arteria cerebral anterior y sus variantes. Resultados: se encontraron 60 segmentos precomunicantes. La longitud promedio del lado izquierdo fue de 11.35 mm y del derecho de 11.84 mm. El calibre medio en el lado izquierdo fue de 1.67 mm y en el derecho de 1.64 mm. El número promedio de perforantes en el lado izquierdo fue de 7.9 y en el derecho de 7.5. La arteria comunicante anterior se encontró en 29 encéfalos sobre el quiasma óptico, su trayecto dependió de la longitud del segmento A1. La longitud media del segmento fue de 2.84 mm, el calibre fue de 1.41 mm y el número promedio de perforantes de 3.27. En 18 encéfalos (60%) se encontraron variantes del complejo A1-arteria comunicante anterior y dos aneurismas tipo blíster. Conclusión: es necesario entender la anatomía microquirúrgica del complejo segmento precomunicante-arteria comunicante anterior y conocer las variantes para tener una visión en tercera dimensión durante la cirugía de aneurismas.

    Full Text Available El conocimiento preciso de los patrones vasculares permite mejorar los resultados de la reconstrucción regional del pabellón auricular y el diseño de colgajos regionales dependientes de la arteria temporal superficial para la reconstrucción facial. En México, no contamos en la actualidad con descripciones anatómicas de las variantes vasculares normales de la arteria temporal superficial. El objetivo de este trabajo es la descripción de las variantes anatómicas de la arteria temporal superficial a través de la disección de este vaso en 12 regiones tempo-parieto-occipitales en cadáveres. Nuestros resultados muestran que la arteria temporal superficial siempre se divide en dos ramas, una anterior y otra posterior, la distribución de ésta se sitúa en el cuarto más posterior de la región temporal, con una bifurcación alta. La distribución de la anatomía vascular, tomando en cuenta el calibre mayor de la arteria temporal superficial con respecto a la arteria auricular posterior, la ausencia de esta última en 4 de las regiones estudiadas, así como la distancia de dichos vasos con respecto al conducto auditivo externo, sugieren que en nuestra población la irrigación del pabellón auricular depende de la arteria temporal superficial, restándole importancia a la aportación del riego sanguíneo de esta región por parte de la arteria auricular posterior. Nuestro estudio arroja resultados que indican la existencia de variaciones importantes en la anatomía vascular regional que justifican la realización de estudios posteriores que permitan una descripción mas detallada de la misma para aumentar el éxito de las intervenciones quirúrgicas.

    Full Text Available La punción percutánea de la arteria radial para la realización de procedimientos por cateterismo ha ganado aceptación debido a una eficacia similar a la obtenida con el acceso femoral. En el presente trabajo evaluamos los resultados obtenidos con la punción repetida de esta arteria. En un total de 182 accesos radiales se realizaron 17 punciones repetidas, y mediante ellas, 20 procedimientos (9 coronariografías y 11 angioplastias. Se obtuvo éxito del acceso en 15 punciones repetidas (88.2% y éxito del procedimiento en todos los casos cuando logramos éxito del acceso. Si bien el grupo es pequeño es suficiente para mostrar que la punción repetida de la arteria radial es factible y permite una alta tasa de éxito de los procedimientos con una disminución ostensible de las complicaciones locales.The radial artery approach for percutaneous cardiac interventions has gained worldwide acceptance due to the similar results obtained by the femoral artery access. In this paper, we report our experience with repeated puncture of the radial artery. One hundred and eighty two radial artery access procedures were performed, in 17 interventions the puncture was repeated once or twice, with a total of 20 therapeutic catheterizations (9 coronary angiographies, 11 angioplasties. There was no therapeutic failure through the radial approach but, we successfully gained access in 88.2% (15/17 of the re-interventions cases. Although an experience with a low number of cases, we had a very high successful therapeutic rate, and also a remarkable lowering of local complications, this shows the feasibility and potential of this technique.

El conocimiento exacto de la integración anatomofisiológica del sistema de conducción del corazón, es fundamental para la comprender la fisiopatología, el diagnóstico y el manejo de muchas de las complicaciones de la enfermedad coronaria y de las cardiopatías en general. Uno de los aspectos fundamentales, más variable y con mayores repercusiones clínicas corresponde al origen y recorrido de las arterias encargadas de irrigar el nódulo sinoatrial. Objetivo. Determinar el origen, recorrido y distribución de las arterias que irrigan el nódulo sinoatrial en una muestra de población colombiana. Material y métodos. La muestra de análisis fueron 60 bloques cardiopulmonares y digestivos seleccionados a través de muestreo por conveniencia. A estos se les realizó una disección convencional de los genitales para la determinación del sexo y posteriormente se procedió con la disección de las arterias coronarias específicamente de la arteria del nódulo sinoatrial, con el fin de establecer su origen y recorrido. Resultados. Como hallazgo principal se encontró que el origen de la arteria del nódulo sinoatrial en 75% provenía de la coronaria derecha, un 15% procedía de la arteria circunfleja y el 10% restante fue codominante. En cuanto al trayecto 86,6% fueron lineales, mientras 13,4% tuvieron formas alternas como Y, doble Y o en tridente. Conclusiones. Se evidenció predominio del origen de la arteria del nódulo sinoatrial en la coronaria derecha, hallazgo coincidente con investigaciones similares e independiente de la procedencia geográfica y el origen racial. Sin embargo, en este estudio se evidenciaron recorridos no reportados en la literatura como la distribución en Y, en doble Y, en K invertida y en tridente.Background.

    Full Text Available La necesidad de restauración del sector anterior, no solo por estética sino para mejorar la función y autoestima del paciente, lleva a pensar en satisfacer estos requerimientos teniendo en cuenta los inconvenientes que dependen del estado inicial, involucrando los tejidos duros y blandos, que pueden llevar a un éxito o fracaso del tratamiento; por lo cual se debe tener una planeación adecuada del tratamiento, dependiendo las características individuales del paciente. La utilización de prótesis realizadas en metal cerámica, que ha venido siendo reemplazada por el uso de sistemas totalmente cerámicos ha llevado a desarrollar materiales con una resistencia y propiedades equivalentes a las prótesis convencionales con el fin de dar un resultado final más estético. Al encontrar pacientes cuya preocupación es el cambio de prótesis removibles por prótesis fijas en los que se encuentra una  mayor pérdida dental, se debe evaluar la posibilidad y  viabilidad de realizar prótesis fijas , que pueden ofrecer resultados más estéticos, sin comprometer la resistencia y duración del tratamiento a largo plazo, además de encontrar condiciones desfavorables como puede ser la perdida de dimensión vertical, o desgastes dentales extensos que requieran de una rehabilitación integral para el éxito del  tratamiento, aspectos importantes para la elección del material ideal para el caso individual del paciente.

    Full Text Available La estenosis de las arterias pulmonares son rara vez diagnosticadas en edad adulta, convirtiéndose su tratamiento en una compleja situación con diferentes posibilidades terapéuticas. Las causas mas frecuentes corresponden a las adquiridas, siendo la mas común la hipertensión pulmonar trombo embolica crónica, quedando un reducido numero de casos congénitos asociado principalmente a síndromes genéticos y malformaciones cardiacas asociadas. El tratamiento quirúrgico convencional puede convertirse en un desafío dadas las condiciones anatómicas y funcionales encontradas en estadios avanzados propias del diagnostico tardío y en especial en el caso presentado el cual esta iniciando la sétima década de la vida. La posibilidad de resolución percutánea de estas lesiones cobra importancia a la luz de la amplia utilización de esta en pacientes pediátricos, implementando el uso cada vez mayor de balones con dilatación percutánea y la utilización de stents cada vez más sofisticados con buenos resultados. Se presenta nuestro primer caso de resolución percutánea de lesiones coronarias y de arteria pulmonar bilateral en un paciente previamente programado para cirugía de reparación con parche y by pass coronario , el cual evoluciono en forma satisfactoria recobrando su actividad normal a las pocas horas del procedimiento.

    Full Text Available Se presenta el caso de un paciente masculino de 38 años de edad, fumador inveterado, con antecedentes de hipertensión arterial esencial, que ingresó en el Hospital Universitario Manuel Ascunce Doménech, de Camagüey, por presentar dolor precordial intenso. En la radiografía de tórax se encontró una imagen opaca bien delimitada a nivel parahiliar izquierdo, motivo por el cual se le practicaron diversas exploraciones complementarias como tomografía axial computarizada y ecocardiografía que revelaron la presencia de una dilatación aneurismática de la arteria pulmonar izquierda. El diagnóstico se concluyó como un aneurisma idiopático de la arteria pulmonar. Debido a que el paciente mejoró clínicamente y el tratamiento quirúrgico entrañaba mucho riesgo para su vida, se optó por el manejo conservador y control periódico.

    Full Text Available Con el desarrollo de los colgajos miocutáneos de recto abdominal (TRAM, el abdomen inferior ha sido reconocido como la principal área dadora de tejidos autólogos de alta calidad, especialmente útiles en reconstrucción mamaria. Más recientemente la habilidad para obtener componentes adiposocutáneos similares sin sacrificar el músculo recto ha revolucionado el campo de la Cirugía Reconstructiva. El advenimiento de los colgajos de perforantes ha permitido a los cirujanos plásticos lograr los mismos buenos resultados estéticos que con los colgajos miocutáneos tradicionales, pero con un considerable descenso en la morbilidad del área donante. Con los colgajos de perforantes de la arteria epigástrica inferior profunda (DIEP y de la arteria epigástrica inferior superficial (SIEA, los pacientes han incrementado sus opciones de reconstrucción. Este artículo revisa la anatomía quirúrgica de la pared abdominal relativa a los colgajos SIEA y DIEP. Se explican detalladamente los pasos principales para la preparación preoperatoria, la técnica quirúrgica y los cuidados postoperatorios. Se discuten las ventajas y desventajas y se presen- tan los trucos técnicos que pueden ayudar a mejorar el resultado final. Además se ilustran con ayuda de casos clínicos las indicaciones típicas y atípicas.Following the development of the transverse rectus abdominis myocutaneous (TRAM flap, the lower abdomen has been recognized as a prime source of high quality autogenous tissue, especially useful in breast reconstruction.

    Full Text Available En este artículo se describen las adaptaciones hechas al algoritmo MARACAS para segmentar y cuantificar estructuras vasculares en imágenes TAC de la arteria carótida. El algoritmo MARACAS, que está basado en un modelo elástico y en un análisis de los valores y vectores propios de la matriz de inercia, fue inicialmente diseñado para segmentar una sola arteria en imágenes ARM. Las modificaciones están principalmente enfocadas a tratar las especificidades de las imágenes TAC, así como la presencia de bifurcaciones. Los algoritmos implementados en esta nueva versión se clasifican en dos niveles. 1 Los procesamientos de bajo nivel (filtrado de ruido y de artificios direccionales, presegmentación y realce destinados a mejorar la calidad de la imagen y presegmentarla. Estas técnicas están basadas en información a priori sobre el ruido, los artificios y los intervalos típicos de niveles de gris del lumen, del fondo y de las calcificaciones. 2 Los procesamientos de alto nivel para extraer la línea central de la arteria, segmentar el lumen y cuantificar la estenosis. A este nivel, se aplican conocimientos a priori sobre la forma y anatomía de las estructuras vasculares. El método fue evaluado en 31 imágenes suministradas en el concurso “Carotid Lumen Segmentation and Stenosis Grading Grand Challenge” 2009. Los resultados obtenidos en la segmentación arrojaron un coeficiente de similitud de Dice promedio de 80.4% comparado con la segmentación de referencia, y el error promedio de la cuantificación de estenosis fue 14.4%.

    Full Text Available La punción percutánea de la arteria radial para la realización de procedimientos por cateterismo ha ganado mayor aceptación en los últimos tiempos. Esto sucedió como consecuencia de haber alcanzado resultados similares a los obtenidos mediante el acceso femoral, con los beneficios de una menor tasa de complicaciones y mayor confort de los pacientes. Recientemente, su utilización tomó un impulso adicional, por estar asociada a mejor pronóstico en síndromes coronarios agudos. En el presente trabajo hemos evaluado si la factibilidad, resultados y ventajas relacionadas al acceso percutáneo de la arteria radial en procedimientos por cateterismo, se aplican también a quienes presentan disección previa de la arteria humeral. Sobre un total de 1 356 accesos radiales percutáneos, 53 fueron en pacientes con disección previa de la arteria humeral, obteniéndose éxito del acceso en el 96.2% (51/53 de las punciones. A través de estos accesos se realizaron 71 procedimientos por cateterismo, con 93.6% (44/47 de éxito del procedimiento en las intervenciones diagnósticas y 100% (24/24 en las terapéuticas. En este grupo no ocurrieron complicaciones mayores. Las complicaciones menores sucedieron en el 1.4% (1/71 de los casos y no se registraron nuevas complicaciones en el seguimiento a siete días. Si bien el grupo es pequeño, consideramos que resulta suficiente para mostrar que las punciones percutáneas de la arteria radial para la realización de procedimientos por cateterismo, en pacientes con disección previa de la arteria humeral, son factibles y permiten elevadas tasas de éxito con baja frecuencia de complicaciones.

    Full Text Available Antecedentes Estudios aleatorizados demostraron la superioridad del uso de stents liberadores de droga (SL sobre el stent convencional (SC. La información en nuestro medio sobre el implante de SL es escasa. Objetivo Comparar los resultados clínicos obtenidos en pacientes sometidos a implante de SL versus SC en un centro terciario de la Argentina. Material y métodos Se incluyeron todos los pacientes sometidos a angioplastia electiva desde abril de 2003 hasta junio de 2005 y se dividieron en dos grupos: los pacientes sometidos a implante de uno o más SL (grupo SL, n = 373 y los sometidos solamente a implante de SC (grupo SC, n = 857. Resultados Las características basales fueron similares entre los dos grupos. En el grupo SL se observó un porcentaje mayor de lesiones en la arteria descendente anterior (50,6 versus 40,6%; p 0,001, gracias a una reducción de la tasa de cirugía coronaria (1,4% versus 5,8%; p = 0,045. Conclusión El uso de SL en un centro terciario de la Argentina demostró que es seguro y, en comparación con el implante de sólo SC, dio por resultado una tasa menor de reintervención, primariamente por haber reducido la tasa de cirugía de revascularización miocárdica

    ómico, administrativo, psicosocial y de información. Participaron 200 adolescentes primigestas (10 a 19 años atendidas en una unidad básica de salud del municipio de Indaiatuba (Sureste de Brasil, en 2003. Se aplicó a las participantes en el momento de su primera consulta pre-natal un cuestionario con preguntas abiertas y cerradas referentes al acceso al último servicio de salud utilizado, anterior a la gestación. Los datos fueron analizados por medio de la prueba de Chi cuadrado de Pearson o exacto de Fischer y por regresión logística múltiple, considerando las cinco dimensiones del acceso. RESULTADOS: Más de la mitad (63,7% de las adolescentes utilizó algún servicio de salud para consulta ginecológica. Entre las que nunca consultaron un ginecólogo, las justificativas dadas fueron falta de información (43,8% o sentimiento de miedo o vergüenza (37,0%. La principal dificultad de acceso al servicio estuvo relacionada con barreras psicosociales, identificadas por 77,0% de las adolescentes. CONCLUSIONES: Entre las barreras de acceso al servicio de salud, fueron significativas solo las psicosociales. Son necesarias nuevas estrategias para facilitar el acceso al servicio de salud a las adolescentes, incluyendo acciones que disminuyan las barreras de género y que se consideren sus características sociodemográficas y el vínculo con sus parejas.OBJECTIVE: To assess determinants of access to primary care services prior to pregnancy by pregnant adolescents. METHODS: Theory-based cross-sectional study conducted to examine access to heath services at five dimensions: geographic, economic, administrative, psychosocial and information. There were included in the study 200 first-time pregnant adolescents (aged 10 to 19 years who attended a primary care unit in the municipality of Indaiatuba, Southeastern Brazil, in 2003. Data was collected using a semi-structured questionnaire applied in face-to-face interviews conducted just before their first pre-natal care visit. Data analyses

    Purpose: This study was designed to investigate the long-term angiographic and clinical outcomes of percutaneous transluminal angioplasty (PTA) of the arteria profunda femoralis (PFA), in a series of patients suffering from critical limb ischemia (CLI) or severe intermittent claudication (IC). Methods: Our department's database was searched to identify patients who underwent PTA or bail-out stenting of the PFA. Among the study's inclusion criteria were Rutherford categories 3-6 and {>=}70% stenosis of the PFA. Only de novo stenotic lesions were assessed. Primary endpoints were technical success, angiographic lesion primary patency, angiographic binary in-lesion restenosis, and target lesion recanalization (TLR) rates. Secondary endpoints included patient survival, limb salvage, and complication rates. Patient's baseline demographics, lesion, and procedural details were analyzed. Results: Between 2001 and 2011, 20 consecutive patients (17 males) with a mean age of 73 {+-} 9 (range 53-87) years underwent PTA or bail-out stenting in 23 PFA lesions. Critical limb ischemia was the indication in eight of 20 patients (40%). The mean lesion length was 31 {+-} 9.5 mm. The procedural technical success was 100% (23/23), whereas mean time angiographic and clinical follow-up was 26.8 {+-} 24.6 months. According to the Kaplan-Meier analysis, primary patency and binary restenosis rate were 95 and 86.1% respectively up to 8 years follow-up. No TLR procedures were performed. The 8-year patient survival and limb salvage rates were 87.5 and 84.7% respectively. Conclusions: PTA or stenting of focal, stenotic, PFA lesions, in patients suffering from CLI or IC, exhibit high long-term primary patency rates, as well as low binary restenosis and TLR rates. Large, multicenter studies are required to validate these results.

  8. Dissektion der Arteria carotis als Ursache ischämischer zerebrovaskulärer Ereignisse - Fallberichte und Diskussion

    2003-01-01

    Full Text Available Dissektionen der kraniozervikalen Gefäße, inbesondere der Arteria carotis, zählen zu den häufigsten Ursachen ischämischer zerebrovaskulärer Ereignisse bei jüngeren Patienten. Die ischämische Symptomatik wird durch eine Wühlblutung in die Gefäßwand verursacht, welche entweder zu einer Minderung des zerebralen Blutflusses und/oder zu einer lokalen Thrombosierung mit nachfolgender Embolisation führt. Karotisdissektionen können durch ein mechanisches Trauma hervorgerufen werden, sie entstehen aber auch spontan oder sind dann bei einem Teil der Patienten mit Bindegewebserkrankungen assoziiert. Zu den häufigsten Symptomen zählen Kopfschmerzen, zervikaler Schmerz und Horner-Syndrom. Die zerebrale Ischämie führt meist zu einer transienten ischämischen Attacke (TIA oder zu einem ischämischen Infarkt im Stromgebiet der Arteria cerebri media der betroffenen Seite. Auch eine Amaurosis fugax kann auftreten. Trotz neuer technischer Möglichkeiten stellen Dissektionen der hirnversorgenden Gefäße nach wie vor eine diagnostische Herausforderung dar. Die digitale Subtraktionsangiographie gilt derzeit noch als Goldstandard zur Diagnostik, wird aber in vielen Fällen zunehmend durch neue nichtinvasive bildgebende Verfahren ersetzt oder ergänzt. Stenose oder Verschluß des betroffenen Gefäßes bilden sich in den meisten Fällen innerhalb von zwei Monaten nach dem Ereignis zurück. Therapeutische Maßnahmen haben vor allem die Verhinderung embolischer Komplikationen zum Ziel. Die gegenständliche Arbeit soll anhand von Fallbeispielen und einer Literaturübersicht klinisch relevante Aspekte und Probleme bei Diagnostik und Therapie der Dissektion der Arteria carotis aufzeigen.

    Full Text Available La preservación del nivel de amputación tanto de la extremidad superior como de la inferior, puede mejorar la función residual y el proceso de rehabilitación protésica de la misma. Ambas van a estar condicionadas por la longitud restante de la extremidad, la presencia o no de articulaciones operativas y la calidad de la cobertura del muñón. Presentamos 2 casos de amputaciones. El primero es un caso agudo de amputación traumática de extremidad superior a la altura del tercio proximal de antebrazo, que asocia avulsión cutánea circular desde el tercio medio del brazo y con articulación de codo conservada. El segundo, es la secuela de una amputación infracondílea de extremidad inferior por osteosarcoma que presenta fístulas cutáneas con drenaje supurativo por osteomielitis en el muñón tibial. En ambos pacientes realizamos cobertura con colgajo anterolateral de muslo anastomosado a la arteria radial en el caso de la extremidad superior, y a la arteria genicular descendente en la extremidad inferior. En los dos casos el postoperatorio transcurrió sin complicaciones, logrando preservar las articulaciones del codo y de la rodilla respectivamente, así como la posterior rehabilitación protésica. Consideramos que el colgajo anterolateral del muslo permite aportar tejido de buena calidad como cobertura del muñón de amputación. Dadas las características del tejido aportado y su volumen, es idóneo tanto para cobertura de defectos agudos como de déficits de almohadillado en casos crónicos.

    Full Text Available El ECG es el método más simple para el diagnóstico de infarto inferior (IAMinf; sin embargo, su utilidad disminuye para determinar el vaso responsable. Objetivos 1. Analizar la utilidad del desnivel del ST en aVR en la identificación de oclusión de las arterias coronaria derecha (CD o circunfleja (CX. 2. Evaluar la utilidad agregada a los criterios clásicos. Material y métodos Se incluyeron en el estudio 65 pacientes con IAMinf a quienes se les realizó una cinecoronariografía (CCG durante la internación. Se analizaron los criterios clásicos, así como el desnivel del ST en aVR: ?ST =?1 mm, ?ST =?1 mm o nivelado (isoST a 0,08 seg del punto J y se calcularon la sensibilidad (S, la especificidad (E, el valor predictivo positivo (VPP, el valor predictivo negativo (VPN y el likelihood ratio (LR. Se incluyó la derivación aVR en un análisis multivariado para determinar su valor agregado a los criterios clásicos. Resultados La CD fue responsable de la oclusión en 47 pacientes (72% y la CX en 18 (28%. Signos clásicos : CD : la relación del ?STD3/D2 =?1 se halló en 52 pacientes (91,5%; p = 0,001 e ?STD1-aVL =?1 mm en 34 (61%; p 1 en 13 pacientes (50%; p = 0,001 y ?STV5-V6 =?1 mm en 12 (44%; p < 0,001. Derivación aVR : CD : ?ST o isoST en 46 pacientes (81%; p < 0,001; CX : ?ST =?1 mm en 19 (56%; p < 0,001. En el análisis multivariado, el ?ST o isoST en aVR identificó a la CD (OR IC 95% 4,7 (1,1-19,8; p = 0,03, mientras que el ?ST aVR identificó a la CX. Se propone un algoritmo diagnóstico para CD que refleja el valor aditivo de aVR a la presencia de los signos clásicos: ?ST o isoST en aVR (VPP 94%; LR+: 2. Conclusión La derivación aVR es una herramienta útil para la identificación de la arteria responsable en el IAMinf, ya que brinda información diagnóstica adicional a los signos clásicos.

    2004-07-01

    Full Text Available El Tribunal Supremo ha condenado a varios obstetras por informar que el cordón umbilical tenía los tres vasos, desactivando así la búsqueda de enfermedades fetales que la arteria umbilical única (AUU habría desencadenado. La condena será éticamente correcta si la AUU está realmente asociada a tales enfermedades. En la población general se detecta un caso de AUU en cada 320 fetos estudiados ecográficamente. En el 68 % de esas detecciones se tratará de un hallazgo aislado, pero aún así aumenta el riesgo de parto prematuro, de peso bajo y de mortalidad perinatal. Por otra parte, el 17 % de estos fetos tendrán, además de la arteria única, cromosomopatías y el 31 % malformaciones anatómicas. Concluyendo, la AUU es realmente un marcador cardinal de riesgo de trastornos fetales, que debe buscarse activamente durante el seguimiento ecográfico del embarazo.

    Full Text Available Las quemaduras eléctricas producen lesiones profundas, especialmente las debidas a la entrada y salida de la corriente y al arco voltaico, que pueden dejar expuestas estructuras nobles y afectar áreas de flexo-extensión, como la fosa antecubital. Los defectos resultantes pueden cubrirse mediante colgajos libres o pediculados de brazo y antebrazo. Entre las distintas opciones quirúrgicas, el colgajo medial del brazo evita la interrupción de los ejes vasculares mayores y la secuela en la zona donante es discreta. Sin embargo, su uso está poco extendido por considerarse un colgajo de difícil disección debido a la variabilidad anatómica de las arterias colaterales cubitales superior e inferior que lo irrigan. Presentamos la cobertura para un defecto secundario a quemadura eléctrica en la fosa antecubital mediante un colgajo medial del brazo basado en las ramas perforantes de la arteria colateral cubital inferior. Aunque confirmamos en este caso la variabilidad vascular, la disección resultó sencilla y el resultado estético y funcional fue excelente.

The chest x-ray showed a well-defined opaque image at the left parahiliar. This supported the performance of several complementary examinations such as a computed tomography and an echocardiography that revealed the presence of an aneurismal dilatation of the left pulmonary artery. The concluding diagnosis was that of an idiopathic aneurysm of the pulmonary artery. Because the patient showed clinical improvements and the surgical treatment was of high risk for his life, it was decided to follow a conservative approach including regular monitoring.Se presenta el caso de un paciente masculino de 38 años de edad, fumador inveterado, con antecedentes de hipertensión arterial esencial, que ingresó en el Hospital Universitario Manuel Ascunce Doménech, de Camagüey, por presentar dolor precordial intenso. En la radiografía de tórax se encontró una imagen opaca bien delimitada a nivel parahiliar izquierdo, motivo por el cual se le practicaron diversas exploraciones complementarias como tomografía axial computarizada y ecocardiografía que revelaron la presencia de una dilatación aneurismática de la arteria pulmonar izquierda. El diagnóstico se concluyó como un aneurisma idiopático de la arteria pulmonar. Debido a que el paciente mejoró clínicamente y el tratamiento quirúrgico entrañaba mucho riesgo para su vida, se optó por el manejo conservador y control periódico.

    2014-09-01

    Congenital anterior urethral diverticulum (CAUD) may be found all along the anterior urethra and may present itself at any age, from infant to adult. Most children with this condition present with difficulty in initiating micturition, dribbling of urine, poor urinary stream, or urinary tract infection. A careful history will reveal that these children never had a good urinary stream since birth, and the telltale sign is a cystic swelling of the penile urethra. In this paper, we present two cases of CAUD that were managed by excision of the diverticulum with primary repair. PMID:26328174

  18. ADAPTACIÓN DEL ALGORITMO MARACAS PARA SEGMENTACIÓN DE LA ARTERIA CARÓTIDA Y CUANTIFICACIÓN DE ESTENOSIS EN IMÁGENES TAC Adaptation of the MARACAS Algorithm for Carotid Artery Segmentation and Stenosis Quantification on CT Images

    Directory of Open Access Journals (Sweden)

    MARIA A ZULUAGA

    Full Text Available En este artículo se describen las adaptaciones hechas al algoritmo MARACAS para segmentar y cuantificar estructuras vasculares en imágenes TAC de la arteria carótida. El algoritmo MARACAS, que está basado en un modelo elástico y en un análisis de los valores y vectores propios de la matriz de inercia, fue inicialmente diseñado para segmentar una sola arteria en imágenes ARM. Las modificaciones están principalmente enfocadas a tratar las especificidades de las imágenes TAC, así como la presencia de bifurcaciones. Los algoritmos implementados en esta nueva versión se clasifican en dos niveles. 1. Los procesamientos de bajo nivel (filtrado de ruido y de artificios direccionales, presegmentación y realce destinados a mejorar la calidad de la imagen y presegmentarla. Estas técnicas están basadas en información a priori sobre el ruido, los artificios y los intervalos típicos de niveles de gris del lumen, del fondo y de las calcificaciones. 2. Los procesamientos de alto nivel para extraer la línea central de la arteria, segmentar el lumen y cuantificar la estenosis. A este nivel, se aplican conocimientos a priori sobre la forma y anatomía de las estructuras vasculares. El método fue evaluado en 31 imágenes suministradas en el concurso Carotid Lumen Segmentation and Stenosis Grading Grand Challenge 2009. Los resultados obtenidos en la segmentación arrojaron un coeficiente de similitud de Dice promedio de 80,4% comparado con la segmentación de referencia, y el error promedio de la cuantificación de estenosis fue 14,4%.This paper describes the adaptations of MARACAS algorithm to the segmentation and quantification of vascular structures in CTA images of the carotid artery. The MARACAS algorithm, which is based on an elastic model and on a multi-scale eigen-analysis of the inertia matrix, was originally designed to segment a single artery in MRA images. The modifications are primarily aimed at addressing the specificities of CT

    Erdmann, Alfons

    2014-04-01

    Full Text Available [english] Background: A tremendous number of free flaps have been developed in the past. As the surgical result depends not only on a successful flap transfer but also on the harvest, this paper details the procedures for undertaking the first total endoscopic harvest of a serratus fascia flap for free flap transplantation to the lower leg. Patient and methods: In September 2012 we performed the first total endoscopic serratus anterior fascia free flap harvest. The incision of 2.5 cm length was made 10 cm in front of anterior muscle border of the latissimus dorsi at level with the midthorax. After insertion of a flexible laparoscopic single port system we started CO gas insufflation. We used this setting to meticulously prepare a neo cavity between atissimus dorsi and M. serratus anterior. The vessels were dissected and the thoraco-dorsal nerve was separated. With a second auxiliary incision we used a clamp to support the raising of the fascia flap from the underlying muscle. Finally we clipped the vessels to the latissimus dorsi muscle and the flap vessels at the Arteria and Vena axillaris. The flap was extracted via the 2.5 cm incision.Results: We were able to perform a total endoscopic harvest of a serratus fascia flap for free flap reconstruction of soft tissues. With this new operative technique we were able to avoid a long skin incision, which in our view lowers the morbidity at the harvest area.Conclusion: We describe a new method for the total endoscopic harvest of the serratus fascia flap for free flap transfer. The flap was harvested within reasonable time and following surgery leaves the patient with minimal donor site morbidity compared to the open technique.

    Full Text Available Antecedentes y Objetivos. La mamoplastía de reducción periareolar es una técnica poco invasiva. Su característica principal es el dejar una cicatriz camuflada en el margen areolar. El objetivo del presente artículo es presentar la anatomía del pedículo central en mamoplastia de reducción con incisión periareolar, la técnica quirúrgica, una serie de pacientes operadas, y revisar la literatura al respecto. Pacientes y Método. Empleamos para el estudio anatómico 24 mamas de 12 cadáveres frescos femeninos, basándonos en la irrigación mediante ramas de la arteria mamaria interna, que irriga el complejo areolo-mamilar y su estuche cutáneo. La técnica consiste en desepitelizar un segmento cutáneo, previamente demarcado alrededor de la areola, telescopar la glándula desde su estuche cutáneo, resecar el tejido mamario deseado mediante cuñas que posteriormente se suturan, y cerrar la incisión alrededor de la areola pasando de una circunferencia mamaria mayor a una de menor diámetro. Presentamos además la experiencia del primer autor en 35 pacientes operadas con la técnica descrita. Resultados. Identificamos una rama de la quinta arteria intercostal en el 80% de las disecciones anatómicas realizadas en cadáveres inyectados con Microfil®, y una rama de la cuarta arteria intercostal en el 20% de los especímenes, que asegura la irrigación del complejo areolo-mamilar y del estuche cutáneo. En las 35 pacientes operadas con la técnica periareolar usando el pedículo central, 5 ellas (14% presentaron complicaciones menores, sin requerir reintervenciones ni hospitalización. Los resultados fueron adecuados. Conclusiones. Consideramos que la técnica de reducción mamaria con incisión periareolar es segura y proporciona buenos resultados si se hace una adecuada selección de pacientes y la realiza un profesional calificado. Se recomienda para pacientes jóvenes, con piel elástica, distancia clavícula-pezón de hasta 25 cm, y con

  2. Anterior hip pain.

    O'Kane, J W

    1999-10-15

    Anterior hip pain is a common complaint with many possible causes. Apophyseal avulsion and slipped capital femoral epiphysis should not be overlooked in adolescents. Muscle and tendon strains are common in adults. Subsequent to accurate diagnosis, strains should improve with rest and directed conservative treatment. Osteoarthritis, which is diagnosed radiographically, generally occurs in middle-aged and older adults. Arthritis in younger adults should prompt consideration of an inflammatory cause. A possible femoral neck stress fracture should be evaluated urgently to prevent the potentially significant complications associated with displacement. Patients with osteitis pubis should be educated about the natural history of the condition and should undergo physical therapy to correct abnormal pelvic mechanics. "Sports hernias," nerve entrapments and labral pathologic conditions should be considered in athletic adults with characteristic presentations and chronic symptoms. Surgical intervention may allow resumption of pain-free athletic activity. PMID:10537384

    Full Text Available Introducción La oclusión total de la aorta abdominal es de presentación poco frecuente y afecta más a menudo a mujeres de edad mediana con antecedentes de tabaquismo y dislipidemia. El punto de partida de la terapéutica endovascular en la aorta fue la angioplastia en las arterias ilíacas y fue progresando desde el balón hasta la colocación de stents.ObjetivoComunicar nuestros resultados inmediatos y el seguimiento a mediano plazo de pacientes con oclusión de la aorta abdominal tratadas con stents por vía endovascular.Material y métodosDesde octubre de 1998 a mayo de 2005 en nuestro servicio se trataron 5 pacientes de sexo femenino por oclusión total de la aorta abdominal, con síntomas de claudicación grave de ambos miembros inferiores. Los procedimientos se realizaron con anestesia local y sedación. Por vía femoral, se intenta recanalizar con las cuerdas de Whooley o hidrófila Glidewire. Posteriormente se realiza un angiograma abdominal e intercambio por cuerda Amplatz con la cual se avanza el balón para realizar las dilataciones antes de implantar el stent. Las pacientes con lesiones ilíacas también se trataron con stent. El índice tobillo-brazo era de 0,71. El promedio de hospitalización fue de 2 días. Al alta se indicaron clopidogrel y aspirina como medicación antiplaquetaria, excepto la primera paciente (ticlopidina y aspirina.

    2008-12-01

    Full Text Available El tratamiento endovascular de los aneurismas de aorta abdominal es una alternativa a la cirugía abierta para pacientes de alto riesgo. Consiste en la exclusión del saco aneurismático mediante la interposición de una endoprótesis colocada por vía femoral. El tratamiento endovascular no puede ser utilizado en todos los pacientes. Una limitación frecuente la constituye el nacimiento de una arteria visceral desde el saco aneurismático. Para contrarrestar esta limitación recientemente se han desarrollado endoprótesis fenestradas que presentan orificios que se corresponden con el nacimiento de las arterias involucradas en el aneurisma evitando su oclusión, permitiendo de esta manera el tratamiento endovascular. En esta comunicación se presenta un caso de tratamiento endovascular de un aneurisma de aorta abdominal mediante la colocación de una endoprótesis fenestrada en un paciente cuya arteria renal izquierda nacía directamente del saco aneurismático.Endovascular treatment of the abdominal aortic aneurysm is consider an alternative to open surgery for high risk patients. Its goal is to exclude the aneurysm from the circulation by using an endoprothesis introduced from a femoral approach. Patients must be strictly selected to avoid possible complications. The most frequent limitation is related to anatomic contraindications such as visceral arteries involved in the aneurysm. Fenestrated endograft have been recently developed to allow endovascular treatment when anatomic features contraindicate classic endovascular procedures. Fenestrated endograft have holes that match with the origin of the visceral arteries maintaining its potency. In this paper we report the endovascular treatment of an abdominal aortic aneurysm by using a fenestrated endoprothesis in a patient whose left renal artery is originated from the aneurysm.

  5. Cierre de zona donante de colgajo libre radial de antebrazo con colgajo de rotación-avance basado en perforantes cubitales

    2013-09-01

    Full Text Available La transferencia libre del colgajo radial de antebrazo se emplea en la práctica clínica habitual en numerosos procedimientos reconstructivos. Sin embargo, también es popular debido a la potencial morbilidad que se genera en la zona donante del colgajo: trastornos vasculares, motores, sensitivos o estéticos. A pesar de haberse realizado numerosas modificaciones tanto en la disección del colgajo como en el cierre del defecto, hasta la actualidad ninguno de los procedimientos empleados ha demostrado paliar completamente estas secuelas. Presentamos nuestra experiencia con la utilización de un colgajo de rotación-avance en V-Y fasciocutáneo basado en los vasos perforantes de la arteria cubital para el tratamiento del defecto resultante de la transferencia libre del colgajo antebraquial radial. Hemos empleado este procedimiento en 7 pacientes con edades comprendidas entre los 30 y los 86 años. Las dimensiones del colgajo radial en el eje longitudinal del antebrazo fueron desde los 4 a los 5,5 cm, con un eje transversal al pedículo vascular desde los 8 a los 10 cm. En todos los casos se conservó la motricidad de antebrazo- muñeca-mano-dedos sin registrarse adherencias a nivel tendinoso. No observamos alteraciones en la fuerza ni en la sensibilidad respecto al preoperatorio en el antebrazo intervenido. Las cicatrices fueron estéticamente aceptables. Concluimos que el colgajo fasciocutáneo de rotación-avance en V-Y basado en perforantes de la arteria cubital aporta numerosas ventajas frente a los injertos cutáneos u otros sustitutos dérmicos, además de ser más barato, con un período de cicatrización más rápido y con un resultado estético superior.

    Objective. To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for knee arthroscopy.Design. An anterior approach to the knee joint was devised mimicking anterior portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidance a needle was advanced from a position adjacent to the patellar tendon into the knee joint. After confirmation of the needle tip location, a dilute gadolinium solution was injected.Results and conclusion. All the arthrograms were technically successful. The anterior approach to knee MRA has greater technical ease than the traditional approach with little patient discomfort. (orig.)

    2010-01-01

    Full Text Available Estudios han identificado que comportamientos, emociones y estrés están asociados con la enfermedad de arterias coronarias (EAC. Existe soporte a la hipótesis de que una zona de la corteza cerebral, ligada con las emociones, se activa ante condiciones estresantes y genera respuestas como hipertensión e infarto. Los aspectos que preceden o generan estrés y comportamientos de riesgo para EAC no son abordados en la atención en salud, y su estudio se ha centrado en la ansiedad o la depresión. La pregunta fue: ¿cuáles son los estados afectivos y emociones más frecuentes y predominantes que subyacen a la experiencia del estrés en las personas con EAC, y su diferencia según algunas características socio-demográficas? Métodos: estudio transversal correlacional, participaron 65 personas con EAC. Se empleó un cuestionario sobre 38 estados afectivos y emocionales para identificar las emociones características según frecuencia, predominio y fuerza de aparición. Resultados: se identificaron 12 características predominantes, de las cuales 10 los define afectivamente: hipersensibilidad, impaciencia, infalibilidad, miedo, excesiva preocupación por otros, autorrepresión emocional, rigidez moral, deseo de ser ejemplo para otros, sobreprotección, soledad y aislamiento. Estas se correlacionaron significativamente con la culpa, el sentimiento de infelicidad, la desolación, la angustia extrema y la desesperanza. Discusión: la excesiva importancia a la razón, al reconocimiento por otros, en detrimento de expresión de emociones y necesidades afectivas, señala conflictos internos persistentes, deficiente autocuidado y estrés emocional. Se sugiere investigar aspectos emocionales para prevención temprana y rehabilitación.

    Full Text Available Objetivo: apresentar os aspectos clínicos, diagnósticos e terapêuticos de pacientes portadores de válvula da uretra anterior. Descrição: em dois neonatos, o diagnóstico presuntivo de patologia obstrutiva do trato urinário foi sugerido pela ultra-sonografia realizada no período pré-natal, confirmando-se o diagnóstico de válvula de uretra anterior pela avaliação pós-natal. Os pacientes foram submetidos a tratamento cirúrgico paliativo, com vesicostomia temporária e, posteriormente, definitivo, pela fulguração endoscópica das válvulas. Ambos evoluíram com função renal normal. Comentários: a válvula da uretra anterior é anomalia rara que deve ser considerada em meninos com quadro radiológico pré-natal sugestivo de obstrução infravesical, secundariamente à hipótese mais comum de válvula da uretra posterior. Ressaltamos a utilização da vesicostomia como derivação urinária temporária nestes casos, prevenindo potenciais complicações pela manipulação da uretra do recém-nascido.Objective: to discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. Description: signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was performed in both patients. Later, the valves were fulgurated using an endoscopic procedure. During the follow-up period both patients presented normal renal function. Comments: anterior urethral valves are a rare form of urethral anomaly that must be ruled out in boys with pre-natal ultrasound indicating infravesical obstruction. Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra.

    Full Text Available El Tribunal Supremo ha condenado a varios obstetras por informar que el cordón umbilical tenía los tres vasos, desactivando así la búsqueda de enfermedades fetales que la arteria umbilical única (AUU habría desencadenado. La condena será éticamente correcta si la AUU está realmente asociada a tales enfermedades. En la población general se detecta un caso de AUU en cada 320 fetos estudiados ecográficamente. En el 68 % de esas detecciones se tratará de un hallazgo aislado, pero aún así aumenta el riesgo de parto prematuro, de peso bajo y de mortalidad perinatal. Por otra parte, el 17 % de estos fetos tendrán, además de la arteria única, cromosomopatías y el 31 % malformaciones anatómicas. Concluyendo, la AUU es realmente un marcador cardinal de riesgo de trastornos fetales, que debe buscarse activamente durante el seguimiento ecográfico del embarazo.The Spanish Supreme Court has condemned several obstetricians after having informed that the umbilical cord of a fetus had the three vessels, therefore deactivating the search for fetal diseases that the single umbilical artery (SUA would have provoked. The sentence will be ethically correct only if SUA is really associated with such diseases. SUA is found in about 1 out of every 320 fetuses studied sonographically. In 68% of them, it will be an isolated finding, although it will increase the risks of premature delivery, low birthweight, and perinatal mortality. On the other hand, 17% of these fetuses will have, besides SUA, chromosomal alterations, and 31 % of them, structural malformations. In conclusion, SUA is an important marker of fetal disorders, and it has to be actively searched for during the ultrasonographic monitoring of the gestation.

    cerebrale, retro-orbitaria e splancnica (splenoportale, mesenterica e renale) nei pazienti derodermici. Materiale e metodi. Il gruppo di studio (GS) e composto da 50 pazienti affetti da sclerodermia con anamnesi negativa per malattie cerebrovascolari, epatopatie, nefropatie e oftalmopatie. In tutti i pazienti e stata studiata la vasodilatazione endotelio-mediata dell'arteria brachiale tramite la misurazione del diametro trasverso con sonda ad alta risoluzione; sono stati anche misurati l'indice di resistenza (IR) delle arterie cerebrale media, centroretinica, epatica propria, mesenterica superiore e renali, in condizioni basali e dopo tre giorni di terapia. AI fine di valutare la variabilita intra-osservatore delle misurazioni, e stato reclutato un gruppo di controllo (GC) composto da 10 volontari sani che sono stati studiati con il medesimo protocollo Doppler e rivalutati a distanza di tre giorni senza ricevere alcuna terapia. Risultati. Il GS ha dimostrato un significativo incremento della dilatazione endotelio-mediata dell'arteria brachiale, del diametro e della velocita media di flusso portale, dell'IP dell'arteria splenica all'ilo (pre-Prostavasin vs post-Prostavasin, p < 0,001). AI contrario il GC non ha mostrato significative variazioni dei parametri considerati. Gli IR delle arterie cerebrale media, centroretinica, renale, epatica propria e mesenterica superiore si sono ridotti dopo terapia nella maggioranza dei pazienti del GS pur non risultando statisticamente significativi. Conclusioni. Nel campione esaminato il Prostavasin ha dimostrato una potente azione vasodilatatoria prevalentemente a livello periferico ed ha incrementato la velocita media di flusso portale ed il diametro della vena porta, ma anche l'IP dell'arteria splenica all'ilo, non supportando l'ipotesi formulata da altri autori di una sua azione mirata e specifica sulle resistenze intraepatiche.

  8. Anterior chest wall examination reviewed

    2011-09-01

    Full Text Available Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondiloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the “activity” of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

CONCLUSIONES: La dilatación de la arteria braquial mediada por flujo se muestra importante como herramienta diagnóstica y pronóstica en la evaluación de la función endotelial de niños y adolescentes con exceso de peso, por ser un método no invasivo, con buena aplicabilidad respecto al costo, a la inclusión y al beneficio.OBJECTIVE: Literature review on the use of the variation measure of the brachial artery diameter by high-resolution ultrasound (flow-mediated dilation as a predictor of cardiovascular disease risk in children and adolescents. DATA SOURCE: Survey of studies indexed in Medline/Pubmed, which were published between 2002 and 2011 using the following keywords in various combinations:"endothelium," "child", "ultrasonography" and "obesity", as well as classic texts on the subject. We found 54 publications and 32 were included in this review. SYNTHESIS OF DATA: The study of endothelial dysfunction has been used as a predictor of risk for cardiovascular diseases such as atherosclerosis and coronary heart disease, since endothelial injury is an important event in the physiopathology of these diseases. CONCLUSIONS: The flow-mediated dilation of the brachial artery seems to be important as a diagnostic and prognostic tool to assess endothelial function in children and adolescents who are overweight, because it is a noninvasive method with good profile regarding cost, safety, and benefits.

  10. Positioning of anterior teeth in removable dentures

    Strajnić Ljiljana

    2002-01-01

    Full Text Available Introduction The aim of this paper was to present methods of placement of artificial anterior teeth in edentulous individuals. The following review takes account of the majority of papers published during the last 100 years. The review has been divided into sections regarding the method used to determine the position of artificial anterior teeth. Geometric aspect Gysi (1895-1920 produced the first scientific theory about the position of artificial anterior teeth. Physiognomic theory The aim of this theory is to find the most natural position for artificial anterior teeth for each individual. Camper's "face angle" as a physiognomic criterion, has been introduced in papers of Wehrli (1961, Marxhors (1966, Tanzer (1968, Lombardi (1973. Esthetic aspect Important names in the field of dental esthetics are: Schön and Singer (1961, Arnheim (1965, Krajiček (1969, Tanzer (1968, Lombardi (1973, Goldstein (1976. They have introduced principles of visual aspects for selection of contours, dimension and position of artificial anterior teeth. Constitution aspect Flagg (1880, Williams (1913 and Hrauf (1957, 1958, have considered body constitution and individual characteristics regarding position of artificial anterior teeth. Physiological theory In 1971, Marxhors pointed to the fact that the position of artificial teeth corresponds with the function of the surrounding soft tissue and from the aspect of physiognomy as well. Phonetic aspect According to Silverman (1962 artificial anterior teeth are nearest when we pronounce the sound "S". Cephalometrical research Rayson (1970, Watson (1989, Strajnić Lj. (1999, Bassi F. (2001 have presented cephalometric radiographic analyses of natural anterior teeth compared with cephalometric radiographic analyses of artificial anterior teeth. A review of dental literature shows several factors suggesting modalities which should determine the position of artificial anterior teeth. Numerous methods have been designed for

    Full Text Available Herniation of the anterior lens capsule is a rare abnormality in which the capsule bulges forward in the pupillary area. This herniation can be mistaken for an anterior lenticonus where both the capsule and the cortex bulge forward. The exact pathology behind this finding is still unclear. We report the clinical, ultrasound biomicroscopy (UBM and histopathological findings of a case of herniation of the anterior lens capsule. UBM helped to differentiate this entity from anterior lenticonus. Light microscopy revealed capsular splitting suggestive of capsular delamination and collection of fluid (aqueous in the area of herniation giving it a characteristic appearance.

    J. O. Trelles

    1971-03-01

    Full Text Available A propósito de un caso de reblandecimiento limitado al territorio arterial anterior y mediano del bulbo que se traducía, clínicamente, por una hemiplejía controlateral con trastornos sensitivos y ausencia de compromiso del facial o de la lengua, y del análisis de 8 casos anatomo-clínicos encontrados en una revisión bibliográfica, los autores discuten el problema de la irrigación arterial del bulbo, el cuadro clínico y el tan debatido asunto de la pretendida flaccidez de estas hemiplejias. Desde el punto de vista de la vascularización arterial del bulbo, se insiste en que ésta es compleja y variable según que se trate del sector oral contiguo a la protuberancia, del sector caudal contiguo a la médula o del sector intermediario a los dos. Desde el punto de vista clínico, en los casos típicos, se trata de una hemiplejia espástica con trastornos sensitivos sin compromiso del facial, ni del hipogloso. De los nueve casos anatomo-clínicos registrados hasta el presente, seis con larga sobrevida, presentaron hemiplejia espástica; dos, con sobrevidas cortas, se encontraban en la etapa de transición hacia la espasticidad; uno con lesiones extensas presentó una flaccidez permanente. En lo que se refiere al problema de la pretendida flaccidez de estas hemiplejias vemos que las hemiplejías bulbares no escapan a la regla de las lesiones del haz piramidal, las que después de una primera etapa de flaccidez evolucionan hacia la espasticidad. Por tanto las conclusiones doctrinarias referentes al haz piramidal basadas en ésta pretendida flaccidez de la hemiplejía bulbar son erróneas y deben revisarse.

    Full Text Available El artículo muestra los orígenes de lo que Walmsley (2008 denomina «investigación inclusiva». Para comprender qué se entiende por investigación inclusiva tenemos que remontarnos a los debates epistemológicos sobre las metodologías cuantitativas y cualitativas, acontecidos en la década de los 90, en torno a la revista Disability & Society. A partir de una síntesis de dichos debates, focalizados en el ámbito de la «discapacidad intelectual y del desarrollo», se exponen dos estrategias de colaboración con dicha población: a una aproximación etnográfica (de trabajo grupal, y b una aproximación biográfica (de trabajo individual. A continuación se esboza un posible diseño de trabajo de campo que intenta superar el paradigma cualitativo «clásico» con el objetivo de incluir a dicho colectivo más allá del rol de «sujetos de la investigación». Para finalizar se recoge el debate sobre la accesibilidad de los resultados de la investigación a los participantes en dichas investigaciones, y con ello la necesaria innovación en el ámbito de las «devoluciones» de los resultados, cuando se trata de incluir a personas que presentan limitaciones para la comprensión del lenguaje abstracto oral y/o escrito.

    2011-12-01

    Full Text Available Toxic anterior segment syndrome (TASS is a sterile intraocular inflammation caused by noninfectious substances, resulting in extensive toxic damage to the intraocular tissues. Possible etiologic factors of TASS include surgical trauma, bacterial endotoxin, intraocular solutions with inappropriate pH and osmolality, preservatives, denatured ophthalmic viscosurgical devices (OVD, inadequate sterilization, cleaning and rinsing of surgical devices, intraocular lenses, polishing and sterilizing compounds which are related to intraocular lenses. The characteristic signs and symptoms such as blurred vision, corneal edema, hypopyon and nonreactive pupil usually occur 24 hours after the cataract surgery. The differential diagnosis of TASS from infectious endophthalmitis is important. The main treatment for TASS formation is prevention. TASS is a cataract surgery complication that is more commonly seen nowadays. In this article, the possible underlying causes as well as treatment and prevention methods of TASS are summarized.

    Background The aims of this study were to investigate the clinical characteristics of patients with combined anterior instability and superior labrum from anterior to posterior (SLAP) lesions, and to analyze the effect of concomitant SLAP repair on surgical outcomes. Methods We retrospectively reviewed patients who underwent arthroscopic stabilization for anterior shoulder instability between January 2004 and March 2013. A total of 120 patients were available for at least 1-year follow-up. Forty-four patients with reparable concomitant detached SLAP lesions (group I) underwent combined SLAP and anterior stabilization, and 76 patients without SLAP lesions (group II) underwent anterior stabilization alone. Patient characteristics, preoperative and postoperative pain scores, Rowe scores, and shoulder ranges of motion were compared between the 2 groups. Results Patients in group I had higher incidences of high-energy trauma (p = 0.03), worse preoperative pain visual analogue scale (VAS) (p = 0.02), and Rowe scores (p = 0.04). The postoperative pain VAS and Rowe scores improved equally in both groups without significant differences. Limitation in postoperative range of motion was similar between the groups (all p-value > 0.05). Conclusions Anterior instability with SLAP lesion may not be related to frequent episodes of dislocation but rather to a high-energy trauma. SLAP fixation with anterior stabilization procedures did not lead to poor functional outcomes if appropriate surgical techniques were followed. PMID:27247742

    Full Text Available Las opciones terapéuticas y reconstructivas disponibles hoy en día para las mujeres con cáncer mamario son numerosas. De los métodos disponibles para la reconstrucción mamaria autóloga el colgajo recto abdominal ha sido el más popular. Es un colgajo que incluye la piel, el tejido graso y el músculo recto abdominal, este conjunto es llevado con su irrigación de la arteria epigástrica superior hasta el defecto de la mastectomía, en el tórax. El colgajo recto abdominal (TRAM ha sido calificado por algunos líderes en el campo de la Cirugía Plástica como el procedimiento más ingenioso realizado en esta especialidad. Entre abril de 1999 y diciembre 2000 realizamos 15 reconstrucciones mamarias utilizando el TRAM. La reconstrucción fue unilateral en catorce casos y bilateral en un caso. En trece pacientes se utilizó un pedículo contralateral y en dos el pedículo fue ipsilateral. Como complicaciones tuvimos dos hernias abdominales, una necrosis grasa parcial y un hematoma, todas fueron resueltas satisfactoriamente. La reconstrucción inmediata ofrece ventajas sobre la reconstrucción retardada . En nuestro país podemos realizar tanto la reconstrucción retardada como inmediata y en los equipos de trabajo (oncólogos, cirujanos generales, cirujanos plásticos, psiquiatras, etc se debe fomentar la reconstrucción inmediata.

    1997-01-01

    The proposed skiing injury mechanism that suggests a quadriceps muscle contraction can contribute to anterior cruciate ligament rupture was biomechanically investigated. The effect of quadriceps muscle force on a knee specimen loaded to anterior cruciate ligament failure during anterior tibial translation was studied in a human cadaveric model. In both knees from six donors, average age 41 years (range, 31 to 65), the joint capsule and ligaments, except the anterior cruciate ligament, were cut. The quadriceps tendon, patella, patellar tendon, and menisci were left intact. One knee from each pair was randomly selected to undergo destructive testing of the anterior cruciate ligament by anterior tibial translation at a displacement rate of 30 mm/sec with a simultaneously applied 889 N quadriceps muscle force. The knee flexion during testing was 30 degrees. As a control, the contralateral knee was loaded correspondingly, but only 5 N of quadriceps muscle force was applied. The ultimate load for the knee to anterior cruciate ligament failure when tested with 889 N quadriceps muscle force was 22% +/- 18% higher than that of knees tested with 5 N of force. The linear stiffness increased by 43% +/- 30%. These results did not support the speculation that a quadriceps muscle contraction contributes to anterior cruciate ligament failure. In this model, the quadriceps muscle force protected the anterior cruciate ligament from injury during anterior tibial translation.

    Kanski, J J

    1981-09-01

    The clinical features of 290 children with anterior uveitis are presented. The vast majority suffered from chronic uveitis. Specific uveitis entities in children include the syndrome of 'chronic iridocyclitis' in girls, heterochromic cyclitis, and pars planitis. Systemic associations include sarcoidosis, the Vogt-Harada-Koyanagi syndrome, and the seronegative arthritides (juvenile chronic arthritis, juvenile ankylosing spondylitis, psoriatic arthritis, and rarely Reiter's and Beçet's syndromes). Children with a pauciarticular onset of juvenile chronic arthritis, especially when combined with positive findings for antinuclear antibody, are at particular risk of developing chronic anterior uveitis. Most cases of chronic anterior uveitis can be controlled with topical corticosteroids. Those that are resistant to both topical and systemic corticosteroids may have to be treated with chlorambucil. The operation of lensectomy is a great advance in the management of complicated cataract. Secondary glaucoma is the most devastating complication of chronic anterior uveitis in children and responds poorly to therapy.

  16. Anterior Eye Imaging with Optical Coherence Tomography

    Science.gov (United States)

    Huang, David; Li, Yan; Tang, Maolong

    The development of corneal and anterior segment optical coherence tomography (OCT) technology has advanced rapidly in recently years. The scan geometry and imaging wavelength are both important choices to make in designing anterior segment OCT systems. Rectangular scan geometry offers the least image distortion and is now used in most anterior OCT systems. The wavelength of OCT light source affects resolution and penetration. An optimal choice of the OCT imaging wavelength (840, 1,050, or 1,310 nm) depends on the application of interest. Newer generation Fourier-domain OCT technology can provide scan speed 100-1000 times faster than the time-domain technology. Various commercial anterior OCT systems are available on the market. A wide spectrum of diagnostic and surgical applications using anterior segment OCT had been investigated, including mapping of corneal and epithelial thicknesses, keratoconus screening, measuring corneal refractive power, corneal surgery planning and evaluation in LASIK, intracorneal ring implantation, assessment of angle closure glaucoma, anterior chamber biometry and intraocular lens implants, intraocular lens power calculation, and eye bank donor cornea screening.

    Full Text Available Con base en la premisa de que la lectura de textos literarios tiene una función formadora y que esta se acentúa en la adolescencia, me propongo demostrar que el cuento “Rapunzel” puede utilizarse como estrategia para explorar algunas situaciones que los sujetos adolescentes perciben como particulares en relación con su vida, pero que se inscriben dentro de grandes problemáticas estudiadas por varias disciplinas. Para ello, he identificado, desde dos marcos de referencia (sociológico y psicoanalítico, diversas problemáticas y discursos que se desprenden de la lectura del cuento realizada por dos mujeres adolescentes, quienes respondieron una guía de lectura y participaron en una entrevista a profundidad. Concluyo que la lectura y comentario del cuento hacen posible que una serie de experiencias que los sujetos adolescentes viven como únicas (como el embarazo de una amiga, las críticas de las personas adultas y las exigencias de padres y madres, ingresen en el circuito de los conocimientos generales al relacionarlas con los discursos y problemáticas en que se inscriben (por ejemplo, el discurso de la “crisis” de la adolescencia, el enfoque de derechos humanos, el mundo fantasmático materno. Por ello, recomiendo la lectura y comentario de textos literarios como estrategia didáctica para contribuir a la elaboración de la subjetividad de personas adolescentes.

    Casi la generalidad de los estudios realizados sobre cementos con adición de cenizas volantes se refieren a sus características y comportamiento en pastas, morteros y hormigones, siempre en relación con aquéllos del cemento portland. Esta vez, se desarrolló un trabajo experimental orientado a relacionar entre sí los cementos con adiciones de cenizas volantes y de puzolana natural. Para ello se fabricaron a escala de laboratorio cementos de ambos tipos, empleando como materias primas comunes clinker y yeso y, como variables, diferentes porcentajes de las dos adiciones, que cumplieron previamente los requisitos normalizados en cuanto a sus actividades puzolánicas. La calidad de los cementos fabricados resultó adecuada y concordante con la del cemento portland-puzolánico obtenido a escala industrial con los mismos clinker, yeso y puzolana natural de este estudio. Posteriormente, se determinaron las características de los cementos experimentales y se confeccionaron morteros normales para la realización de ensayos físicos y mecánicos. Los resultados de ensayos indicaron que los cementos con adición de cenizas volantes (CCV requieren menos agua para consistencia normal, presentan tiempos de fraguado mayores y expansiones en autoclave menores que los cementos con adición de puzolana (CP. Los calores de hidratación a 7 y 28 días de edad fueron aproximadamente similares para ambos tipos de cemento. En morteros normales, los cementos CCV mostraron menor retracción de secado, mayor retentividad y mayor fluidez (para igual cantidad de agua que los cementos CP. En los ensayos de exudación se observó que ésta depende más de la finura que el tipo de adición. Finalmente, los ensayos mecánicos señalaron que las resistencias a compresión y flexotracción de los morteros con cementos CCV son menores a edades inferiores que 14 días (del orden de 5 a 10% a un día de edad, pero que a partir de entonces pasan a ser mayores que las de

If already in 1889 Giuseppe Sergi wanted that the artificial selection take it to end what should make the natural, avoiding the risk of the so called «degeneration», only in the face of the First World War seems to grow the alarm for the decadent quality of the population, finding a more and more wide echo. In 1919 the Siges was born (Società italiana de genetica ed eugenica shocked under the impression of the difusse fear about the butcher the war had caused. From there from now on fastens a «nazional» direction closely related to the traditional thought and also with the new political temper.

Over the years, since there are no fascial or anatomic planes, anatomists and radiologists have suggested various schemes for subdividing the mediastinum and several anatomical and radiological classifications of the mediastinum are reported in the literature. The most popular of these scheme divides medistinum, for purposes of description, into two parts: an upper portion, above the upper level of the pericardium, which is named the superior mediastinum; and a lower portion, below the upper level of the pericardium. For clinical purposes, the mediastinum may be subdivided into three major areas, i.e. anterior, middle, and posterior compartments. The anterior mediastinum is defined as the region posterior to the sternum and anterior to the heart and brachiocephalic vessels. It extends from the thoracic inlet to the diaphragm and contains the thymus gland, fat, and lymph nodes. This article will review surgical anatomy of the anterior mediastinum and will focus on the surgical approch to anterior mediastinum and thymic diseases.

  12. Esthetic crown lengthening for maxillary anterior teeth.

    Sonick, M

    1997-08-01

    In the maxillary anterior region, the gingival labial margin position is an important parameter in the achievement of an ideal smile. The relationship between the periodontium and the restoration is critical if gingival health and esthetics are to be achieved. Periodontal therapy is a necessary and useful adjunct when any anterior restoration is undertaken. Anterior surgical crown lengthening may be undertaken to avoid restorative margin impingement on the biologic width. Crown lengthening is also used to alter the gingival labial profiles. This article discusses the esthetic parameters of ideal gingival labial positions and presents a classification of crown-lengthening procedures and the procedure for a two-stage crown-lengthening technique. The two-stage crown-lengthening technique is surgically precise because healing is predictable.

    Full Text Available Thymolipoma is a rare benign tumor of anterior mediastinum, described by Lange in 1916. 1 Less than 200 cases have been reported worldwide. 2 It accounts for 2% to 9% of thymic tumours. 3 We report a case of thymolipoma in a 37 year s old male patient, who pre sented with cough, dys p nea, chest pain for 2 months. CT THORAX revealed a large anterior mediastinal mass extending in to right hemithorax arising from thymus gland, with multiple areas of fat density, no significant mediastinal adenopathy, complete collap se of right middle and lower lobe suggestive of thymolipoma. CT guided biopsy suggestive of thymic neoplasm. The tumour was removed enbloc through surgery. Histopathological examination of large mass lesion confirmed thymolipoma. We report this case to emp hasize the importance of considering thymolipoma as a differential diagnosis of anterior mediastinal mass, although rare.

    Full Text Available Michelle Chen Lynch,1 Andrew B Mick21Optometry Clinic, Ocala West Veterans Affairs Specialty Clinic, Ocala, FL, USA; 2Eye Clinic, San Francisco VA Medical Center, San Francisco, CA, USABackground: Anterior scleritis is an uncommon form of ocular inflammation, often associated with coexisting autoimmune disease. With early recognition and aggressive systemic therapy, prognosis for resolution is good. The diagnosis of underlying autoimmune disease involves a multidisciplinary approach.Case report: A 42-year-old African American female presented to the Eye Clinic at the San Francisco Veteran Affairs Medical Center, with a tremendously painful left eye, worse on eye movement, with marked injection of conjunctiva. There was mild swelling of the upper eyelid. Visual acuity was unaffected, but there was a mild red cap desaturation. The posterior segment was unremarkable. The initial differential diagnoses included anterior scleritis and orbital inflammatory disease. Oral steroid treatment was initiated with rapid resolution over a few days. Orbital imaging was unremarkable, and extensive laboratory work-up was positive only for antinuclear antibodies. The patient was diagnosed with idiopathic diffuse, nonnecrotizing anterior scleritis and has been followed for over 5 years without recurrence. The rheumatology clinic monitors the patient closely, as suspicion remains for potential arthralgias including human leukocyte antigen-B27-associated arthritis, lupus-associated arthritis, seronegative rheumatoid arthritis, recurrent juvenile idiopathic arthritis, and scleroderma, based on her constitutional symptoms and clinical presentation, along with a positive anti-nuclear antibody lab result.Conclusion: Untreated anterior scleritis can progress to formation of cataracts, glaucoma, uveitis, corneal melting, and posterior segment disease with significant risk of vision loss. Patients with anterior scleritis must be aggressively treated with systemic anti

    Full Text Available Congenital coronary artery anomalies are uncommon. Dual left anterior descending coronary artery (LAD is defined as the presence of two LADs within the anterior interventricular sulcus (AIVS, and is classified into four types. Type IV is a rarely reported subtype and differs from the others, with a long LAD originating from the right coronary artery (RCA. Dual LAD is a benign coronary artery anomaly, but should be recognised especially before interventional procedures. With the increasing use of multidedector computed tomography (MDCT, it is essential for radiologists to be aware of this entity and the cross-sectional findings.

    Full Text Available Radiologist always examines X-ray to determine abnormal changes in cervical, lumbar & thoracic vertebrae. Osteophyte (bony growth may appear at the corners of vertebrae so that vertebral shape becomes abnormal. This paper presents the idea from Image processing techniques such as customised Hough transform which will be used for segmentation which should be independent of rotation, scale, noise & shape. This segmented image will be then used for computing size invariant, convex hull based features to differentiate normal cervical vertebrae from cervical vertebrae containing anterior osteophyte. This approach effectively finds anterior osteophytes in cervical vertebrae.

    Full Text Available Duby, heredero de dos grandes historiadores como Marc Bloch y Lucien Febvre, es uno de los más importantes medievalistas europeos. Fue, y sigue siendo, un motor de la importante reforma en la historia producida desde los sesenta. En sus primeros trabajos se acusa la recepción de las ideas económicas y geográficas de la mejor historiografía. Su riguroso estudio sobre la base material de la Edad Media, le permitirá luego irrumpir en la historia de las mentalidades, analizando, como decía Febvre, el utillaje mental (vocabulario, sintaxis, lugares comunes, cuadros lógicos, etc. del Medioevo. Así, el ejemplo de Mauss y LéviStrauss le anima a trabajar sobre el matrimonio, la sexualidad y ciertos sistemas del pensamiento: el primero, con su defensa de los hechos sociales totales, y el segundo, que buscaba las dimensiones simbólicas de lo social, le impulsan a trabajar sobre la ideología entendida no como mero reflejo de la situación material sino como «proyecto de acción sobre lo vivido». A su obra individual, atenta a los impulsos culturales más vivos, se suma su empuje decisivo en la realización de proyectos colectivos como la Historia de la vida privada o la Historia de las mujeres. Prácticamente, han sido traducidos todos sus libros al castellano, y han podido verse en España asimismo varios de sus programas televisivos (ha sido presidente de la SEPT, cadena de televisión cultural fundada en 1985. La amplitud de sus intereses intelectuales, transmitidos en su obra con un lenguaje a la vez muy claro y bellamente elaborado, se hace palpable también en este diálogo.

    Directory of Open Access Journals (Sweden)

    Miesje K. Purwanegara

    2015-09-01

    Full Text Available Anterior teeth movement in orthodontic treatment is limited to labiolingual direction by very thin alveolar bone. An uncontrolled anterior tooth movement to labiolingual direction can cause alveolar bone perforation at its root segment. This case report is to remind us that alveolar bone thickness limits orthodontc tooth movement. A case of crowded anterior teeth with thin alveolar bone in malocclusion I is reported. This case is treated using adgewise orthodontic appliance. Protraction of anterior teeth is anticipated due to thin alveolar bone on the anterior surface. The conclusion is although the alveolar bone surrounding the crowded anterior teeth is thin, by controlling the movement the teeth reposition is allowed.

    Full Text Available The anterior retropharyngeal approach (ARPA accesses anteriorly situated lesions from the clivus to C3, in patients with a short neck, Klippel Feil anomaly or those in whom the C2-3 and C3-4 disc spaces are situated higher in relation to the hyoid bone and the angle of mandible where it is difficult to approach this region using the conventional anterior approach, due to the superomedial obliquity of the trajectory. The ARPA avoids the potentially contaminated oropharyngeal cavity providing for a simultaneous arthrodesis and instrumentation during the primary surgical procedure. Experience of five patients with high cervical extradural compression, who underwent surgery using this approach between 1994 and 1999, is presented. The surgical procedures included excision of ossified posterior longitudinal ligament (n=2; excision of prolapsed disc and osteophytes (n=2; and excision of a vertebral body neoplasm (n=1. Following the procedure, vertebral arthrodesis was achieved using an iliac graft in all the patients. Only one patient with vertebral body neoplasm required an additional anterior cervical plating procedure for stabilisation the construct. The complications included transient respiratory insufficiency and neurological deterioration in two patients; and, pharyngeal fistula and donor site infection in one patient.

The study sample consisted of 451 surgically treated patients, including 400 sportsmen (65% of them being active and 35% recreational sportsmen, 29% female and 71% male; of whom 90% were younger than 35. Sports injuries, as the most frequent cause of anterior cruciate ligament injuries, were recorded in 88% of patients (non-contact ones in 78% and contact ones in 22%, injuries occurring in everyday activities in 11% and in traffic in 1%. Among sportsmen, reconstruction of the anterior cruciate ligament was most frequently performed in football players (48%, then in handball players (22%, basketball players (13%, volleyball players (8%, martial arts fighters (4%. However, the injury incidence was the highest among the active basketball players (1 injured among 91 active players. Type of footwear, warming up before the activity, genetic predisposition and everyday therapy did not have a significant influence on getting injured. Anterior cruciate ligament injuries happened three times more often during matches, in the middle and at the end of a match and training session (79%, at landing after the jump or when changing direction of movement (75% without a contact with other competitors, on dry surfaces (79%, among not so well prepared sportsmen.

    Full Text Available Gran especialista en historia moderna, Alberto Tenenti nació en Viareggio, en 1924. Tras realizar estudios superiores en Italia, trabajó en el Centre National de la Recherche Scientifique varios años, asesorado por Lucien Febvre. Ha dirigido el Archivo del Estado de Brescia; y, más tarde, ha enseñado en París, desde una cátedra en la École Pratique des Hautes Études en Sciences Sociales (VI Sección, alIado de Braudel. Su Il senso della morte e l'amore della vita nel Rinascimento, de 1957, es una obra maestra sobre los orígenes de la sensibilidad moderna: sin olvidar el naciente vitalismo, estudia el desarrollo de dos motivos, el del ars moriendi, que tiene su evolución propia desde 1350 hasta su difusión impresa, y el de lo macabro, que refleja la crisis de conciencia del siglo XV y adquiere «unas dimensiones desconocidas y verdaderamente anormales». En este libro sobre un problema clave como la muerte, apela de modo notable a la iconografía: Tenenti ha recordado que la cultura tradicional, eclesiástica sobre todo, percibió un mayor peligro en la capacidad de reflexión autónoma y de crítica de los hombres de letras, que en las renovaciones radicales de los artistas. Numerosos trabajos de conjunto realizados por él han perseguido una historia global: Los fundamentos del mundo moderno; Florencia en la época de los Medicis; La formación del mundo moderno; El Renacimiento; el primero de ellos estaba firmado con un historiador de su misma generación, R. Romano, estudioso de las relaciones comerciales en la época moderna en Europa y en la América española. Tenenti ha publicado monografías (Venezia e i corsari, 1961, colecciones de artículos (Credence, ideologie, libertinismi tra medioevo ed eta moderna, 1978; Stato: un'idea, una logica.

    Full Text Available This paper describes one of the three bridges which Hidrocivil, S. A., has built in Catalonia (northern Spain, over the river Ripoll. The other two bridges are very similar to this one, both in construction and design, and show only minor adjustments to the local topography. The contracting firm proposed several alterations in the prefabrication and constructional procedure, in relation to the initial project, and these changes were accepted. The main feature of these projects is the use of prestressed beams, built at the workshop in sections, and joined together by means of sixty 7 mm cables in each beam. As the shear forces are more acute at the joints, the end of each section has a kind of diaphragm, to provide a large contact area, and hence greater surface to transmit the shear forces. The methods of construction are also of interest. Briefly, they involve building the bridge piles, and use these to support a provisional structure with transversal movement. This provisional structure, in turn, served as platform for two bridge cranes, which lifted the girders to their final location. After the first span was completed, the deck was concreted and the auxiliary structure pushed forward to the next span, to repeat the same operations. This arrangement saved the use of provisional framework.En este trabajo se describe uno de los tres puentes que Hidrocivil, S. A., ha construido.—previo concurso— en la región catalana; concretamente, el que salva el río Ripoll. Los otros dos no han sido objeto de descripción general por ser muy similares, en lo que a ejecución y concepción se refiere, con la única variante que presentan las características topográficas locales. La empresa propuso ciertas variantes— que fueron aceptadas— en la prefabricación y métodos de construcción. El interés de estas obras se centra en el empleo de vigas pretensadas, prefabricadas en taller por trozos, y solidarizados en el mismo mediante las operaciones

    In the acute setting, accurate radiological interpretation of paediatric cervical spine trauma can be difficult due to a combination of normal variants and presence of multiple synchondroses. We present a rare case of a fracture through the anterior atlantal synchondrosis in a paediatric spine. A five-year-old boy, who fell backwards onto the top of his head while swinging across on a monkey bar frame, presented with neck pain, cervical muscle spasm and decreased right lateral rotation and extension of his neck. Computed tomography showed a displaced diastatic fracture through right anterior atlantal synchondrosis. There are only 12 cases of paediatric C1 fractures reported in the world literature. The importance of considering this diagnosis in the appropriate clinical setting, and the normal variants in the paediatric atlas that can cause diagnostic dilemma to the interpreting radiologist, are discussed in this case report.

    The ocular and systemic characteristics of 160 patients with anterior uveitis and seronegative juvenile rheumatoid arthritis are reviewed. Chronic uveitis occurred in 131 patients, 76% of whom were girls. Both eyes were involved in 70% of the cases. Band keratopathy occurred in 41% of the eyes, cataract in 42%, and secondary glaucoma in 19%. Only 11 patients had uveitis before the onset of arthritis. Notable correlations included a pauciarticular onset of arthritis in 95% of the patients, and positive tests for antinuclear antibody in 82%. Of 29 patients with acute anterior uveitis, 27 were boys. The inflammation responded well to therapy, and serious complications did not occur. At follow-up 21 patients had typical ankylosing spondylitis, and five had sacroiliitis. The incidence of positive results of tests for HLA-B27 antigen was 94%.

    Full Text Available Aim. The aim of this study is to introduce a new technique, anterior vaginal wall darn (AVWD, which has not been used before to repair the anterior vaginal wall prolapse, a common problem among women. Materials and Methods. Forty-five women suffering from anterior vaginal wall prolapse were operated on with a new technique. The anterior vaginal wall was detached by sharp and blunt dissection via an incision beginning from the 1 cm proximal aspect of the external meatus extending to the vaginal apex, and the space between the tissues that attach the lateral walls of the vagina to the arcus tendineus fascia pelvis (ATFP was then darned. Preoperation and early postoperation evaluations of the patients were conducted and summarized. Results. Data were collected six months after operation. Cough stress test (CST, Pelvic Organ Prolapse Quantification (POP-Q evaluation, Incontinence Impact Questionnaire (IIQ-7, and Urogenital Distress Inventory (UDI-6 scores indicated recovery. According to the early postoperation results, all patients were satisfied with the operation. No vaginal mucosal erosion or any other complications were detected. Conclusion. In this initial series, our short-term results suggested that patients with grade II-III anterior vaginal wall prolapsus might be treated successfully with the AVWD method.

    MRI of a 62-year-old female presenting with ankle pain demonstrated an accessory muscle within the anterior compartment of the lower leg. The muscle originated from the fibula and anterior crural septum. The tendon passed anterior to the lateral malleolus and inserted at the critical angle of Gissane on the calcaneus. This muscle was initially described in the anatomic literature by Lambert and Atsas in 2010. To our knowledge, this is the first time the MRI appearances of this muscle has been described in the radiological literature. Awareness of the fibulocalcaneal muscle is important as it may represent a cause of ankle pain. In addition, the tendon could potentially be harvested for use in reconstructive procedures. (orig.)

    Full Text Available Las opciones terapéuticas y reconstructivas disponibles hoy en día para las mujeres con cáncer mamario son numerosas. De los métodos disponibles para la reconstrucción mamaria autóloga el colgajo recto abdominal ha sido el más popular. Es un colgajo que incluye la piel, el tejido graso y el músculo recto abdominal, este conjunto es llevado con su irrigación de la arteria epigástrica superior hasta el defecto de la mastectomía, en el tórax. El colgajo recto abdominal (TRAM ha sido calificado por algunos líderes en el campo de la Cirugía Plástica como el procedimiento más ingenioso realizado en esta especialidad. Entre abril de 1999 y diciembre 2000 realizamos 15 reconstrucciones mamarias utilizando el TRAM. La reconstrucción fue unilateral en catorce casos y bilateral en un caso. En trece pacientes se utilizó un pedículo contralateral y en dos el pedículo fue ipsilateral. Como complicaciones tuvimos dos hernias abdominales, una necrosis grasa parcial y un hematoma, todas fueron resueltas satisfactoriamente. La reconstrucción inmediata ofrece ventajas sobre la reconstrucción retardada . En nuestro país podemos realizar tanto la reconstrucción retardada como inmediata y en los equipos de trabajo (oncólogos, cirujanos generales, cirujanos plásticos, psiquiatras, etc se debe fomentar la reconstrucción inmediata.Today, the therapeutic and reconstructive options for mastectomized women are numerous.

    Full Text Available Background: Evaluation of result of anterior cervical approach with manubriotomy and anterior instrumentation in tuberculosis of cervicothoracic spine in terms of the neurological recovery, reconstruction of spine and prevention of deformity along with relief of pain. Materials and Methods: All five patients with cervicothoracic caries spine had surgery through anterior cervical approach with manubriotomy in our hospital and underwent excision of the involved vertebrae and intervertebral discs followed by anterior spinal reconstruction with titanium spacer cage filled with cancellous iliac crest bone graft and Orion plate with locking screw. Antitubercular drugs were administered for 12 months. The follow-up period ranged from 12 to 36 months. Results: Analysis of result was done on the basis of clinical and radiological criteria. Clinical assessment based on Frankel grade and modified JOA score showed significant improvement from preoperative findings. Radiological assessment showed osteointegration, no spinal instability and no progression of the deformity. The pain control, based on visual analog scale changed from a pre-operative average of 7.5 to 2 at the last follow-up thereby indicating significant improvement and all patients returned to preoperative functional status. One patient had transient hoarseness of voice. No other complication had been encountered in the immediate post operative and during the follow-up period. Conclusions: Our study showed that anterior cervical approach with manubriotomy and anterior insertion of titanium cage, filled with autogenous bone graft, secured with locking plate instrumentation has a successful role in the eradication of infection, neurological recovery, segmental spinal reconstruction and it also reduces surgical time, blood loss, and surgical complications and approach related comorbidity in follow up period.

Se enfatiza el uso del método sol-gel para la fabricación de diversos sólidos porosos ya sean mesoporosos y macroporosos. Lo anterior se justifica porque un intenso y reciente interés se ha notado en la síntesis de estructuras que combinan dos matrices porosas, nano y macro lo que aumenta la posibilidad de uso y diversifica sus aplicaciones. Estas preparaciones se hacen a través del proceso sol-gel y el uso de templantes supramoleculares llamados vesículas, lo que vincula la potencialidad de los nanoporos con la flexibilidad de un material macroporoso. Se hace énfasis en el uso apropiado de templantes orgánicos, ya sean moléculas, micelas o vesículas que posibilitan la fabricación de diversos sólidos porosos ordenados. Esto se facilita mediante el uso del proceso sol-gel, que emerge como una de las tecnologías apropiadas para este objetivo

Five of these patients developed TASS postoperatively.Results: Patients had blurred-vision complaints on the first day after the operation, but no pain. They had different degrees of diffuse corneal edema, anterior-chamber reaction, fibrin, hypopyon, iris atrophies, and dilated pupils. Their vision decreased significantly, and their intraocular pressures increased. Both anti-inflammatory and antiglaucomatous therapies were commenced. Corneal edema and inflammation resolved in three cases; however, penetrating keratoplasty was needed for two cases and additional trabeculectomy was needed for one case. Although full investigations were undertaken at all steps, we could not find the causative agent.Conclusion: TASS is a preventable complication of anterior-segment surgery. Recognition of TASS, differentiating it from endophthalmitis, and starting treatment immediately is important. Controlling all steps in surgery, cleaning and sterilization of the instruments, and training nurses and other operation teams will help us in the prevention of TASS.

    Full Text Available Introduction. Infections after anterior cruciate ligament reconstructions are rare, but, on the other hand, they are difficult to be treated. The aim of this study was to analyze causes of infections, risk factors, diagnostics, and possibilities of their prevention. Material and Methods. Seventeen deep infections (1.2% were found in 1425 patients who had undergone anterior cruciate ligament reconstructions. Fifteen patients were males and two were females. Out of 475 professional athletes nine (1.9% had this postoperative complication. Eleven patients with septic arthritis were allergic to penicillin. Three of them had immunosuppressive diseases. Results. Staphylococcus aureus was isolated in eleven cases (65%, other Staphylococcus and Streptococcus groups were found in four and three patients, respectively; while one patient had infection although the punctate was negative. Out of 965 patients with the patellar tendon grafts, ten (1.03% had this complication, while the incidence was 1.52% (7/460 in those with the hamstring grafts. Fifteen infections were acute with obvious symptoms within 14 days after surgery. Severe pain, limited range of motion, swelling of the knee joint and fever were the most common symptoms, while rubor and pus developed rarely. The infection was three times more frequent in the patients who had undergone surgery lasting more than 1.5 hour. Discussion and Conclusion. The following population groups are at risk of developing septic arthritis after anterior cruciate ligament reconstructions: professional athletes, those who are allergic to penicillin, and those with immunosuppressive diseases. Staphyllococus aureus is the most common cause of infection. The patients with the hamstring autografts have a higher risk than those with the patellar tendon grafts. Preventive measures that should be performed include aseptic conditions in operative rooms, irrigation of the graft before its placement into the bone tunnels

    Full Text Available The neural network that contributes to the suffering which accompanies persistent pain states involves a number of brain regions. Of primary interest is the contribution of the cingulate cortex in processing the affective component of pain. The purpose of this review is to summarize recent data obtained using novel behavioral paradigms in animals based on measuring escape and/or avoidance of a noxious stimulus. These paradigms have successfully been used to study the nature of the neuroanatomical and neurochemical contributions of the anterior cingulate cortex to higher order pain processing in rodents.

    Directory of Open Access Journals (Sweden)

    Chih-Hwa Chen

    2014-04-01

    Full Text Available Successful anterior cruciate ligament (ACL reconstruction with tendon graft requires extensive tendon-to-bone healing in the bone tunnels and progressive graft ligamentization for biological, structural, and functional recovery of the ACL. Improvement in graft-to-bone healing is crucial for facilitating early, aggressive rehabilitation after surgery to ensure an early return to pre-injury activity levels. The use of various biomaterials for enhancing the healing of tendon grafts in bone tunnels has been developed. With the biological enhancement of tendon-to-bone healing, biological fixation of the tendon graft in the tunnel can be achieved in ACL reconstruction.

    The purpose of the study was to describe the findings seen on anterior segment spectral domain optical coherence tomography (SD-OCT) in patients with anterior scleritis and determine the feasibility of using SD-OCT to image and grade the degree of scleral inflammation and monitor response to treatment. All patients underwent slit lamp examination by a uveitis specialist, and the degree of scleral inflammation was recorded. Spectral domain OCT imaging was then performed of the conjunctiva and scleral tissue using a standardized acquisition protocol. The scans were graded and compared to clinical findings. Twenty-eight patients with anterior scleritis and ten patients without ocular disease were included in the study. Seventeen of the scleritis patients were followed longitudinally. Common findings on SD-OCT in patients with active scleritis included changes in hyporeflectivity within the sclera, nodules, and visible vessels within the sclera. There was significant variation in findings on SD-OCT within each clinical grade of active scleritis. These changes on SD-OCT improved with treatment and clinical improvement. SD-OCT imaging provided various objective measures that could be used in the future to grade inflammatory activity in patients with anterior scleritis. Longitudinal imaging of patients with active scleritis demonstrated that SD-OCT may have great utility in monitoring response to treatment.

  20. Adjacent Segment Pathology after Anterior Cervical Fusion.

    2016-06-01

    Anterior cervical fusion has become a standard of care for numerous pathologic conditions of the cervical spine. However, subsequent development of clinically significant disc disease at levels adjacent to fused discs is a serious long-term complication of this procedure. As more patients live longer after surgery, it is foreseeable that adjacent segment pathology (ASP) will develop in increasing numbers of patients. Also, ASP has been studied more intensively with the recent popularity of motion preservation technologies like total disc arthroplasty. The true nature and scope of ASP remains poorly understood. The etiology of ASP is most likely multifactorial. Various factors including altered biomechanical stresses, surgical disruption of soft tissue and the natural history of cervical disc disease contribute to the development of ASP. General factors associated with disc degeneration including gender, age, smoking and sports may play a role in the development of ASP. Postoperative sagittal alignment and type of surgery are also considered potential causes of ASP. Therefore, a spine surgeon must be particularly careful to avoid unnecessary disruption of the musculoligamentous structures, reduced risk of direct injury to the disc during dissection and maintain a safe margin between the plate edge and adjacent vertebrae during anterior cervical fusion.

    The purpose of this study was to assess the usefulness of MRI in the evaluation of autografts after anterior cruciate ligament reconstruction. The subjects were 110 patients with anterior cruciate ligament reconstruction using patellar tendon autografts who underwent clinical examination, MRI, and arthroscopy of the knee. T1- and T2-weighted MR images were obtained in sagittal plane. Clinical findings were categorized into three groups: normal, borderline, and abnormal. The MRI appearances of the autografts were categorized into three types: straight continuous band (type I), interrupted band (type II) and generalized increased intensity band (type III). The clinical findings and MRI findings were compared with arthroscopic findings. Ninety-six percent of the type I showed no autograft tear on arthroscopy. In comparison with the clinical findings, MRI was found to be well correlated with arthroscopic findings. In conclusion, if the clinical findings are normal, patients are to be followed-up without MRI and arthroscopy. However, if clinical findings are either borderline or abnormal, MRI should be performed prior to arthroscopy. (author)

    Anterior fixation devices for the thoracolumbar spine have gained wide acceptance as viable alternatives to long-segment posterior fixation in cases of thoracolumbar spine trauma. This review was undertaken to evaluate the safety and efficacy of the Synthes anterior thoracolumbar locking plate (ATLP) system. Over a 3-year period, 31 patients with unstable traumatic fractures of the thoracolumbar spine underwent corpectomy, placement of a structural bone graft, and anterior fixation in which the Synthes ATLP system was used. Long-term follow-up data were obtained in 29 patients. Two patients were lost to follow up, one at 4 months and the other at 1 year. In the remaining patients, the average length of follow up was 20 months. In all patients radiographic evidence of solid bone fusion was demonstrated on follow-up plain x-ray films, and there were no signs or symptoms of pseudarthrosis. No patient suffered neurological deterioration as a result of surgery, and there was relatively little morbidity associated with this plating system. To date, none of the patients in this study has developed any delayed complications related to the fixation device. In one patient, who had sustained a severe flexion injury, loosening of the anterior fixation device occurred, and the patient developed progressive kyphosis, which required a posterior stabilization procedure. These results appear slightly better than those obtained in published studies in which other anterior plating systems were used, indicating that this system is safe and effective in the treatment of unstable fractures of the thoracolumbar spine.

Neste relato de caso de STSA são enfatizadas as causas mais comuns para o aparecimento da síndrome, apontam para os cuidados que devem ser tomados no processo de esterilização do material cirúrgico além de revisar a melhor conduta diante desses casos. Em conclusão notou-se que o foco principal deve ser a prevenção, pois o tratamento busca apenas suprimir a resposta inflamatória secundária. O tratamento nos casos de STSA consiste em intensa instilação de esteróides tópicos com seguimento rigoroso e controle de complicações tardias como o glaucoma.Toxic anterior segment syndrome is acute inflammatory reaction caused by a noninfectious substance that enters the anterior segment, resulting in extracellular damage with necrosis and apoptosis during an immune response. We have the report of a case of toxic anterior segment syndrome (TASS, in which the authors seek to emphasize the most common causes of the appearance of these syndrome. They point out the care that must be taken in the process of sterilization of surgical material, in addition to reviewing the best conduct when faced with these cases. In conclusion, it was noted that the main focus should be on prevention, as treatment only seeks to suppress the secondary inflammatory response. Treatment in cases of toxic anterior segment syndrome (TASS consists of intense instillation of topical steroids with strict follow-up and control of late complications such as glaucoma.

    2014-11-01

    Video-assisted thoracoscopic surgery (VATS) has been widely used, but surgical resections of superior sulcus tumours remain challenging because of their anatomical location. For such cases, less-invasive procedures, such as the anterior transcervical-thoracic and transmanubrial approaches, have been widely performed because of their excellent visualization of the subclavian vessels. Recently, a combined operative technique with an anterior surgical approach and VATS for anterior superior sulcus tumours has been introduced. Herein, we report three cases of anterior superior sulcus tumours successfully resected by surgical approaches combined with a VATS-based lobectomy. In all cases, operability was confirmed by VATS, and upper lobectomies with hilar and mediastinal lymph node dissections were performed. Subsequently, dissections of the anterior inlet of the tumours were performed using the transmanubrial approach in two patients and the anterior trans-cervical-thoracic approach in one patient. Both approaches provided excellent access to the anterior inlet of the tumour and exposure of the subclavian vessels, resulting in radical resection of the tumour with concomitant resection of the surrounding anatomical structures, including the chest wall and vessels. In conclusion, VATS lobectomy combined with the anterior surgical approach might be an excellent procedure for the resection of anterior superior sulcus tumours.

    The lack of reported complications related to lower extremity peripheral nerve blocks (PNBs) may be related to the relatively infrequent application of these techniques and to the fact that most such events go unpublished. Our current understanding of the factors that lead to neurologic complications after PNBs is limited. This is partly the result of our inability to conduct meaningful retrospective studies because of a lack of standard and objective monitoring and documentation procedures for PNBs. We report a case of permanent injury to the sciatic nerve after sciatic nerve block through the anterior approach and discuss mechanisms that may have led to the injury. Intraneural injection and nerve injury can occur in the absence of pain on injection and it may be heralded by high injection pressure (resistance).

Different variables were collected, as shown in. The patients were prospectively evaluated using the WOMAC short form and Kujala scores. An objective evaluation was performed looking for different potential risk factors and using part of the International Knee Documentation Committee (IKDC) score. Radiological evaluation was performed, including the congruence angle, the grade of osteoarthritis (Kellegren-Lawrence) and the patellar tilt angle. Three main outcomes were identified. The multiple logistic regression was used to analyze the correlation between the variables and a worse outcome. Results: 72 cases were included in the study (9 bilateral). 72.2% of the cases were female, and the average age was 42,2 years (SD15,9). The average BMI was 24.4 kg/m2 (SD5,2). In 70.8% of patients a lateral release was associated to the tibial tubercle osteotomy. 77.8% of patients were evaluated clinically, the remaining, who were unable to come for the visits, were interviewed and the subjective scores were administered by phone. The average follow-up was 68.4 months (SD35.5).In 62.5% of cases a valgus lower limb alignment was detected, with 25% and 39.3% of patients having respectively an increased femoral antiversion and foot pronation. Post-operatively there was a statistical significant improvement in all the scores. No differences in the pre-operative and post-operative congruence angle or patellar tilt were detected (p>0.05).

    Full Text Available ABSTRACT We read with interest the article by Surekha et al. regarding the retained stone piece in anterior chamber. Similar to the results of previous studies, the authors found that delayed intraocular foreign body (IOFB management can result in good visual outcome without an apparent increased risk of endophthalmitis or other deleterious side effects. However, the authors failed to explain the exact reason for the diminution of vision in patients left eye. It is unclear what the uncorrected visual acuity was and what kind of correction was used, more precisely type and amount of cylinder, given the presence of the corneal opacity. Since the size of the IOFB is approximately 4x4x1mm, significant irido-corneal angle changes resulting in intraocular pressure raise and optic nerve head damage can be expected. Traumatic glaucoma following open globe injury can occur in 2.7 to 19% of cases, with several risk factors associated with glaucoma development (advanced age, poor visual acuity at presentation,perforating rather than penetrating ocular injury,lens injury, presence of vitreous hemorrhage and presence of an IOFB. Earlier reportsof latetraumaticoptic neuropathy onset, even after several years, indicate that this possibility cannot be completely ruled out too. Therefore, repeated intraocular pressure measurements, gonioscopy, pupillary reaction assessment, together with through posterior segment examination including visual field and optical coherence tomography examinations can be useful in determining the possible optic nerve damage as one of the possible reasons for visual acuity reduction. The authors did not suggest any operative treatment at this time. However, it should bear in mind that the inert anterior chamber IOFB could be a risk factor for non-infectious endophthalmitis development even after many years. Also, long term retained anterior chamber foreign body leads to permanent endothelial cell loss and can even result in a corneal

    Full Text Available Introduction. We present a case of a metallic foreign body embedded in the anterior chamber angle. After standing in close proximity to a construction worker breaking a tile, a 26-year-old woman using soft contact lens for the correction of mild myopia presented to emergency department for evaluation of a foreign body sensation of her right eye. Methods and Results. Diagnosis was confirmed by gonioscopic examination and a noncontrast CT scan of head and orbits. The foreign body was removed by an external approach without utilizing a magnet. The patient's final outcome was favorable. Discussion. The above is a rare clinical situation, which is impossible to detect on slit-lamp examination without a gonioscopic view. Proper imaging and a specific management are mandatory in order to achieve favorable outcome.

    To investigate magnetic resonance (MR) imaging of anterior cruciate ligament (ACL) tears, the authors retrospectively reviewed 39 MR imaging examinations in 39 patients. We classified the MR imaging patterns of the torn ACL into four types. Torn ACL appears as a homogeneous iso-intensity mass on Type I images; as a continuous thin and waving low-intensity band with or without high-signal-intensity spots on the Type II images; as a disrupted band with a high-signal-intensity area on Type III images and as an absence of the ACL on Type IV images. We also report secondary lesions on MR imaging findings associated with tears of the ACL, posterior cruciate ligament index and bone bruising, in our patients. (author).

    On 546 knees, the authors have obtained MR images (0.5 T or 1.5 T). The protocol included 5-mm-thick contiguous sagittal and oblique coronal images (in the plane of the anterior cruciate ligament [ACL]) and T1-, proton-density-, and T2-weighted sequences. In 174 patients, correlations with arthroscopic or surgical findings were available. In these cases, sagittal and oblique coronal images were retrospectively and separately read by two radiologists, who were blinded to other results. The mean accuracy of sagittal MR images alone was 88% for the depiction of partial and complete ACL tears, intraligamental bleeding, and scarring; the accuracy of oblique coronal images alone was 96%. Use of sagittal and oblique coronal images together achieved 98% accuracy

    Bone contusions are an important ancillary finding of many knee injuries. Not only are they a source of pain, they may suggest a mechanism of injury or a specific derangement of the knee joint. We have encountered a small number of patients being evaluated for anterior cruciate ligament (ACL) tears with unexplained patellar and tibial edema at magnetic resonance (MR) imaging. We present three individuals with contusions of the inferior patella with a corresponding contusion of the anteromedial tibial plateau. Internal derangements in these patients were similar to other individuals with acute ACL tears, however osseous contusions were more widespread. In conclusion, patellotibial contusions are rare and may indicate an injury with forces greater than usually encountered in most ACL tears. A careful search for uncommon associated injuries is prudent in these high-energy knee injuries. PMID:24037484

    Full Text Available Odontogenesis is a complex process wherein more than 200 genes are known to play a significant role in tooth development. An imbalance can lead to an abnormality in the number, size, shape or structure of the developing tooth/teeth. The presence of an extra dental lamina forms a supernumerary tooth. The supernumerary teeth are of two types: A rudimentary tooth where the supernumerary tooth does not resemble any tooth in the normal series or a supplemental tooth in which this anomalous tooth resembles one in the normal series. It is also very rare to encounter triple teeth in primary dentition. The union of these teeth may be through fusion, gemination, concrescence or a combination of fusion and gemination. Presented is a rare case of concrescence involving maxillary deciduous incisors and a supplemental tooth in a 7-year-old boy. The differential diagnosis, etiology, and complications of primary anterior triple teeth are discussed.

    The relatively high risk of noncontact anterior cruciate ligament (ACL) rupture among female athletes has been a major impetus for investigation into the etiology of this injury. A number of risk factors have been identified, both internal and external to the athlete, including neuromuscular, anatomical, hormonal, shoe-surface interaction, and environmental, such as weather. The anatomic and neuromuscular risk factors, often gender related, are the focus of most ACL injury prevention programs. Although studies have shown that biomechanic- centered prevention programs can reduce the risk of ACL injury, many questions remain unanswered. More research is needed to increase our understanding of the risk factors for ACL injury; how injury prevention programs work and can the clinical application of such programs be optimized.

    Full Text Available Background: Although microscopic anterior cervical discectomy with or without fusion are common surgical procedures for treatment of cervical herniated discs, loss of disc height, pseudarthrosis, and adjacent disc degeneration are some of the problems associated with it. This study is aimed to evaluate results of endoscopic microforaminotomy in cervical disc diseases. Materials and Methods: A prospective study of 50 patients of mono segmental soft or hard disc causing myeloradiculopathy was undertaken. A visual analogue scale (VAS for neck and arm pain and functional outcomes using the Nurick grading system were assessed. There were 28, 12, 8, and 2 patients at C5-6, C6-7, C4-5, and C3-4 levels disc diseases, respectively. Patients with two or more level disc, instabilities, disc extending more than half vertebral body height, and previous operation at the same segment were excluded. Results: Age ranged from 21 to 67 years. Average postoperative reduction in disc height, operating time, and blood loss was 1.1 mm, 110 minutes, and 30 ml, respectively. Average pre-operative VAS score for arm pain and Nurick grading was 7.6 and 2.7, which improved to 1.9 and 0.82, respectively. All patients improved; 1, 2, 3 grade improvement was seen in 10, 27, and 10 patients, respectively. There was no significant complication or any mortality. Conclusion: Although longer follow up of large number of patients is required, endoscopic microforaminotomy is a safe and an effective alternative to microscopic anterior discectomy with or without fusion.

  11. Etiological aspects of anterior open bite

    Stojanović Ljiljana

    2007-01-01

    Full Text Available Introduction. Open bite is a multifactorial phenomenon and no single factor can account for open-bite. Etiology plays an important role in diagnosis. Heredity, unfavorable growth patterns, incorrect jaw postoure, are the characteristics of skeletal open bite. Digit sucking. Depending on where the thumb is placed, a number of different types of dental problems can develop. Malocclusions of the late mixed or permanent dentitions, caused by thumb sucking are not self corrected and orthodontic treatment is necessary for their correction. Lymphatic tissue. In order to produce oral respiration, the mandible is postured inferiorly with the tongue protruded and resting against the oral floor. This postural alteration induces dental and skeletal modifications similar to those caused by thumb sucking. This may cause excessive eruption of the posterior teeth, leading to an increase in the vertical dimension of the face and result in development of anterior open bite. Tongue thrust. Tongue habits cause an anterior open bite or they develop secondarily to thumb sucking. In skeletal open bite the tongue habit acts as a secondary factor which helps to maintain or exacerbate the condition. Many orthodontists have had a discouraging experience of completing dental treatment, with what appeared to be good results, only to discover that the case had relapsed because the patient had a tongue thrust swallowing pattern. Conclusion. Dentoalveolar or habitual open bite is caused by habits, which influence the growth and development of dentoalveolar processes and contribute to occlusal disharmonies. Prior to eruption of adult dentition, open bite related to oral habits is usually not a concern as when the habits stop, because the erupting dentition tends to improve spontaneously. Treatment is usually not necessary until permanent teeth erupt (~6 years old. .

    Objectives: The purpose of this study was to determine the clinical outcomes following revision anterior shoulder stabilization performed either via all-arthroscopic soft tissue repair or via Latarjet coracoid transfer. Methods: A retrospective review of prospectively collected data on 91 shoulders undergoing revision anterior shoulder stabilization was performed. All patients underwent prior soft tissue stabilization; those with prior open bone grafting procedures were excluded. For patients with 25% glenoid bone loss, Latarjet was performed (n=28). Patients were queried regarding recurrent instability (subluxation or dislocation). Clinical outcomes were evaluated using validated patient reported outcome questionnaires including the American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test (SST), visual analog scale (VAS) for pain, and Western Ontario Shoulder Instability Index (WOSI). Results: A total of 63 shoulders in 62 patients (46 males, 16 females) with an average age of 23.2 ± 6.9 years were included in the revision arthroscopy group. At an average follow-up of 46.9 ± 16.8 months (range, 15 to 78), the mean WOSI score was 80.1 (range, 15.0 to 100), and there were significant improvements (pLatarjet group. Thirteen (46%) had more than one previous stabilization attempt. ), the average WOSI score was 71.9, and there were significant improvements (pLatarjet. Conclusion: Both arthroscopic revision stabilization and Latarjet coracoid transfer result in satisfactory outcomes in patients who have failed previous arthroscopic capsulolabral repair. Recurrent instability rates were higher in the all-arthroscopic group (19% versus 7%). Longer-term studies are required to determine whether similar results are maintained over time, and to provide guidance on focused clinical indications for this challenging patient population.

    Anterior cruciate ligament (ACL) injury in the skeletally immature individual is being recognized with increasing frequency. Nonoperative treatment of ACL injuries in skeletally immature patients have not been favorable. Surgical treatment options for complete ACL tears include primary ligament repair, extraarticular tenodesis, transphyseal reconstruction, partial transphyseal reconstruction, and physeal-sparing reconstruction. The advantage of transphyseal reconstruction is placement of the graft tissue in an isometric position, which provides better results, according to the literature. The potential disadvantage is angular or limb-length discrepancy caused by physeal violation. Controversy exists in allograft selection about whether bone or soft tissue passes into physes. The use of standard tunnels provides reliable results, but carries the risk of iatrogenic growth disturbance from physeal injury.This article presents 4 cases of transphyseal ACL reconstruction using anterior tibialis allograft in skeletally immature patients that had satisfactory functional outcomes with no growth disturbances. This is the first report of transphyseal ACL reconstruction using anterior tibialis allograft in skeletally immature patients in the English-speaking literature. All patients underwent transphyseal ACL reconstruction using anterior tibialis tendon allograft. None of the patients had angular deformities. No early physeal arrest was measured between the preoperative and postoperative radiographs. At last follow-up, the results of the Lachman test were normal for 3 patients and nearly normal for 1 patient. All patients demonstrated full range of knee motion (comparing the reconstructed knee to the contralateral knee). The results of the pivot-shift test were normal for 3 patients and nearly normal for 1 patient. No patients reported giving way.

    A 51-year-old woman presented with a distal anterior cerebral artery aneurysm (DACAA) manifesting as severe headache and monoparesis of the left lower limb. Computed tomography revealed subarachnoid hemorrhage in the interhemispheric fissure, bilateral sylvian fissures, and basal cistern, and a hematoma in the supracallosal region. Angiography showed a large aneurysm (23 x 18 mm) located on the distal end of the azygos anterior cerebral artery (azygos ACA) at the supracallosal portion. T2-weighted magnetic resonance imaging demonstrated the hematoma as a mixed intensity mass, compressing the corpus callosum downward, and the aneurysm as a flow void anterior to the hematoma. Unilateral frontoparietal parasagittal craniotomy was performed with a horse-shoe shaped incision. The aneurysm was clipped via the interhemispheric approach, and the hematoma was aspirated. Postoperative angiography showed disappearance of the aneurysm and intact azygos ACA. The patient was discharged with mild monoparesis, paresthesia of the left lower limb and diagnostic dyspraxia. DACAA almost always arises at or near the genu of the corpus callosum and is often associated with vascular anomaly. In the literature, 22 of 26 cases of large and giant DACAA were located at or near the genu, but only 3 cases, including ours, in the supracallosal area. 11 cases were associated with azygos ACA. Therefore, hemodynamic stress caused by vascular anomaly may be involved in the formation of large or giant DACAA in contrast with cases of normal DACAA. PMID:9789300

    Zebrafish with defective Nodal signaling have a phenotype analogous to the fatal human birth defect anencephaly, which is caused by an open anterior neural tube. Previous work in our laboratory found that anterior open neural tube phenotypes in Nodal signaling mutants were caused by lack of mesendodermal/mesodermal tissues. Defects in these mutants are already apparent at neural plate stage, before the neuroepithelium starts to fold into a tube. Consistent with this, we found that the requirement for Nodal signaling maps to mid-late blastula stages. This timing correlates with the timing of prechordal plate mesendoderm and anterior mesoderm induction, suggesting these tissues act to promote neurulation. To further identify tissues important for neurulation, we took advantage of the variable phenotypes in Nodal signaling-deficient sqt mutant and Lefty1-overexpressing embryos. Statistical analysis indicated a strong, positive correlation between a closed neural tube and presence of several mesendoderm/mesoderm-derived tissues (hatching glands, cephalic paraxial mesoderm, notochord, and head muscles). However, the neural tube was closed in a subset of embryos that lacked any one of these tissues. This suggests that several types of Nodal-induced mesendodermal/mesodermal precursors are competent to promote neurulation.

    The purpose of this study was to analyse the occurrence of variants of anomalous insertions of the anterior horn of the medial meniscus in human knee joints. The study was carried out on 78 human lower limbs of both sexes (42 males and 36 females). Out of 78 knee joints, 10 knee joints (12.82%) presented atypical attachments of the anterior horn of the medial meniscus. In 9 cases we found that the anterior horn of the medial meniscus was attached to the transverse ligament of the knee and in 1 case it was attached to the coronary ligament. In the remaining cases the anterior horn of the medial meniscus was attached to the anterior intercondylar area of the tibia.

    Anterior chamber volume (ACV) is very important for an oculist to make rational pathological diagnosis as to patients who have some optic diseases such as glaucoma and etc., yet it is always difficult to be measured accurately. In this paper, a method is devised to measure anterior chamber volumes based on JPEG-formatted image files that have been transformed from medical images using the anterior-chamber optical coherence tomographer (AC-OCT) and corresponding image-processing software. The corresponding algorithms for image analysis and ACV calculation are implemented in VC++ and a series of anterior chamber images of typical patients are analyzed, while anterior chamber volumes are calculated and are verified that they are in accord with clinical observation. It shows that the measurement method is effective and feasible and it has potential to improve accuracy of ACV calculation. Meanwhile, some measures should be taken to simplify the handcraft preprocess working as to images.

  13. Anterior commissure versus corpus callosum: A quantitative comparison across mammals.

    Mammals rely on two major pathways to transfer information between the two hemispheres of the brain: the anterior commissure and the corpus callosum. Metatheria and monotremes rely exclusively on the anterior commissure for interhemispheric transfer between the isocortices and olfactory allocortices of each side, whereas Eutheria use a combination of the anterior commissure and an additional pathway exclusive to Eutheria, the corpus callosum. Midline cross-sectional area of the anterior commissure and corpus callosum were measured in a range of mammals from all three infraclasses and plotted against brain volume to determine how midline anterior commissure area and its size relative to the corpus callosum vary with brain size and taxon. In Metatheria, the square root of anterior commissure area rises in almost direct proportion with the cube root of brain volume (i.e. the ratio of the two is relatively constant), whereas among Eutheria the ratio of the square root of anterior commissure area to the cube root of brain volume declines slightly with increasing brain size. The total of isocortical and olfactory allocortical commissure area rises more rapidly with increasing brain volume among Eutheria than among Metatheria. This means that the midline isocortical and olfactory allocortical commissural area of metatherians with large brains (about 70 ml) is only about 50% of that among eutherians with similarly sized brains. On the other hand, isocortical and olfactory allocortical commissural area is similar in Metatheria and Eutheria at brain volumes around 1 ml. Among the Eutheria, some groups make less use of the anterior commissure pathway than do others: soricomorphs, rodents and cetaceans have smaller anterior commissures for their brain size than do afrosoricids, erinaceomorphs and proboscideans. The findings suggest that use of the anterior commissural route for isocortical commissural connections may have placed limitations on interhemispheric transfer of

    Full Text Available Cataratas polares anteriores piramidais são opacidades cônicas que se projetam para a câmara anterior a partir da cápsula anterior do cristalino. Na grande maioria dos pacientes a opacidade permanece aderida e estável durante toda a vida. O objetivo deste trabalho é documentar uma manifestação incomum desse tipo de catarata: a deiscência espontânea das pirâmides para a câmara anterior causando descompensação endotelial e edema corneal bilateral. Relatamos o caso de uma paciente feminina, de 66 anos, branca, que apresentava edema corneal localizado inferiormente no olho direito associado à lesão nodular branco-esclerótica compatível com a pirâmide anterior da catarata polar. O olho esquerdo apresentava edema corneal difuso intenso e presença de uma catarata polar anterior com a região piramidal deslocada para a câmara anterior. Sabe-se que a pirâmide anterior pode permanecer inabsorvida na câmara anterior por longo período, pois é composta de tecido colágeno denso. Isto causa perda endotelial progressiva e edema corneal e deve ser considerada indicação de remoção cirúrgica da catarata polar anterior e de seu fragmento. Ressalta-se, também, a importância do bom senso no julgamento das cataratas polares anteriores, considerando-se tamanho da opacidade, simetria das opacidades e componente cortical associado, na tentativa de se evitar ambliopia.Pyramidal anterior polar cataracts are conical opacities that project into the anterior chamber from the anterior capsule of the lens.

El estudio descriptivo correlacional se realizó con 41 niños y sus madres, aplicándose cuestionarios sobre funcionamiento familiar, prácticas de crianza y desarrollo infantil. Los resultados señalaron la existencia de un funcionamiento familiar caracterizado por una cohesión amalgamada y una adaptabilidad caótica, una disciplina complaciente, falta de control y de límites claros en la díada madre-hijo. Se trataba de familias monoparentales, donde la temprana edad de concepción, el madresolterismo y el apoyo de la familia extensa eran constantes. Las edades evolutivas registradas indicaron un desarrollo inferior a la edad cronológica, en la mayor parte de los casos; sin embargo, éstas tendieron a ser superiores al compararlas con la edades reales de los infantes. No se encontró una correlación estadísticamente significativa entre la edad de desarrollo y los diferentes factores del funcionamiento familiar para algunos de los rangos de edad considerados; sin embargo, no se lo descartó por completo, especialmente en lo referente al optimismo familiar

    2015-01-01

    The purpose of this paper was to review the current literature associated with the techniques and materials for the restoration of primary anterior teeth and make clinical recommendations based upon the available literature. A variety of esthetic restorative materials are available to utilize for restoring primary incisors. Awareness of the specific strengths, weakness, and properties of each material can enhance the clinician's ability to make the best choice of selection for each individual situation. Intracoronal restorations of primary teeth may utilize resin composites, glass ionomer cements, resin-modified ionomers, or polyacid-modified resins. Full coronal restoration of primary incisors may be indicated for a number of reasons. Crowns available for restoration of primary incisors include those that are directly bonded onto the tooth, which generally are a resin material, and crowns that are luted onto the tooth and are either some type of stainless steel or zirconia crown. There is insufficient controlled, clinical data to suggest that one type of restoration is superior to another. Operator preferences, esthetic demands by parents, the child's behavior, the amount of tooth structure remaining, and moisture and hemorrhage control are all variables that affect the decision and ultimate outcome of whatever restorative solution is chosen.

    The purpose of this study was to evaluate using MRI the natural healing of the anterior cruciate ligament (ACL) when treated conservatively by early protective motion. Consecutive acute complete intraligamentous ruptures of the ACL in 50 cases that were allowed to heal without surgery were evaluated before and after 3 month treatment by MRI, arthroscopy, and stress radiographs. Twenty-nine of the 50 patients were also reevaluated 11 months from the initial injury, of which 7 were reevaluated again 24 months from the initial injury by MRI. The MR appearance of the treated ACL was categorized into four grades depending on homogeneity, straight band, and size. MR assessment of the ACL after 3 month treatment demonstrated a well defined normal-sized straight band in 37 cases (74%). There was a significant relationship between the 3 and 11 month MR evaluations (r. = 0.801, p < 0.0001). There were also significant relationships between the MR and arthroscopic evaluations (r, = 0.455, p < 0.005) and between the MR and stress radiographic evaluations (r, = 0.348, p < 0.025) after the 3 month treatment. MRI can demonstrate ACL healing when treated conservatively with early protective mobilization. 40 refs., 3 figs., 2 tabs.

    It is known that anterior cruciate ligament (ACL) reconstruction needs to be combined with detailed postoperative rehabilitation in order for patients to return to their pre-injury activity levels, and that the rehabilitation process is as important as the reconstruction surgery. Literature studies focus on how early in the postoperative ACL rehabilitation period rehabilitation modalities can be initiated. Despite the sheer number of studies on this topic, postoperative ACL rehabilitation protocols have not been standardized yet. Could common, "ossified" knowledge or modalities really prove themselves in the literature? Could questions such as "is postoperative brace use really necessary?", "what are the benefits of early restoration of the range of motion (ROM)?", "to what extent is neuromuscular electrical stimulation (NMES) effective in the protection from muscular atrophy?", "how early can proprioception training and open chain exercises begin?", "should strengthening training start in the immediate postoperative period?" be answered for sure? My aim is to review postoperative brace use, early ROM restoration, NMES, proprioception, open/closed chain exercises and early strengthening, which are common modalities in the very comprehensive theme of postoperative ACL rehabilitation, on the basis of several studies (Level of Evidence 1 and 2) and to present the commonly accepted ways they are presently used. Moreover, I have presented the objectives of postoperative ACL rehabilitation in tables and recent miscellaneous studies in the last chapter of the paper. PMID:25232521

    2011-01-01

    Full Text Available Introduction. Deep anterior lamellar keratoplasty (DALK is intended for the surgical treatment of corneal pathology without the involvement of the endothelium. Sparing of the healthy host endothelium for lifetime is of utmost importance in young patients. Therefore, keratoconus is among the main indications for DALK. Outline of Cases. Two men, 22 and 28 years of age, underwent DALK for the treatment of progressive keratoconus, with low visual acuity, impossible to be corrected with gas-permeable contact lenses, due to the extreme conical protrusion of the cornea. Baring of Descemet’s membrane was achieved with lamellar dissection and peeling off the stroma. An 8.5 mm graft without the endothelium was sutured into an 8.0 mm bed. Both grafts remained clear and attached, without either ocular surface pathology or problems arising from sutures. The best corrected visual acuity was 20/25 and 20/40, with the astigmatism of 2.5 and 3.0 diopters, respectively. The follow-up was one year. Conclusion. This is the first presentation of DALK in our literature. The restoration of corneal transparency and stability, with sparing of the host endothelium, has put DALK among successful corneal tranplantation procedures. Together with Descemet stripping endothelial keratoplasty, which already accounts for almost a half of all our keratoplasties, it offers an alternative to penetrating keratoplasty.

    2006-12-01

    Rehabilitation is an important part of therapy in patients who have had arthroscopic anterior cruciate ligament reconstruction. A well-designed rehabilitation program avoids potential graft damage and speeds up patients' return to their full function level. The course of rehabilitation depends on the type of surgery, mode of fixation and possible co-existing injury to the knee's soft tissues. The rehabilitation program presented here is based on the present-day knowledge of neurophysiological and biomechanical principles and is divided into five phases. In the pre-operative phase (I), the main objective is to prepare patients for surgery in terms of maximum muscle strength and range of motion. It also includes providing full information on the procedure. In the early post-operative phase (II) we are concerned with pain alleviation and reduction of knee edema. After suture removal we begin with soft techniques for the patella and post-operative physical therapy to reduce scarring. In the next post-operative phase (III) patients are able to walk with their full weight on the extremity operated on, and we continue doing exercises that improve flexor/extensor co-contraction. In this phase we also begin with exercises improving the patient's proprioceptive and sensorimotor functions. In the late post-operative phase (IV) we go on with exercises promoting proprioception of both lower extremities with the aim of increasing muscle control of the knee joints. In the convalescent phase (V) patients gradually return to their sports activities.

  9. Anterior dental microwear texture analysis of the Krapina Neandertals

    2012-12-01

    Some Neandertal anterior teeth show unusual and excessive gross wear, commonly explained by non-dietary anterior tooth use, or using the anterior dentition as a tool, clamp, or third hand. This alternate use is inferred from aboriginal arctic populations, who used their front teeth in this manner. Here we examine anterior dental microwear textures of the Krapina Neandertals to test this hypothesis and further analyze tooth use in these hominins. Microwear textures from 17 Krapina Dental People were collected by white-light confocal profilometry using a 100x objective lens. Four adjacent scans were generated, totaling an area of 204x276 μm, and were analyzed using Toothfrax and SFrax SSFA software packages. The Neandertals were compared to six bioarchaeological/ethnographic samples with reported variation in diet, abrasive load, and non-dietary anterior tooth use. Results indicate that Krapina anterior teeth lack extreme microwear textures expected of hominins exposed to heavy abrasives or those that regularly generated high stresses associated with intense use of the front teeth as tools. Krapina hominins have microwear attributes in common with Coast Tsimshian, Aleut, and Puye Pueblo samples. Collectively, this suggests that the Krapina Neandertals faced moderate abrasive loads and only periodically used their anterior teeth as tools for non-diet related behaviors.

    To evaluate main numerical parameters of anterior segment and the effects of eyelid skin changes on these parameters in patients with systemic sclerosis (SSc). Thirty-four patients with SSc and 34 healthy individuals were enrolled. Besides full eye examination, anterior segment measurements including anterior chamber depth (ACD), anterior chamber volume, anterior chamber angle width, central corneal thickness, pupil size, corneal volume and keratometry were obtained using a Sirius Scheimpflug/Placido photography-based topography system. Eyelid thickness was evaluated using the scala of the modified Rodnan skin score and the patients were subgrouped with respect to these scores to evaluate the effect of eyelid thickening on the anterior segment parameters. Age and sex distributions of the groups were similar (p > 0.05). SSc patients had steeper and thinner corneas, smaller corneal volumes, narrower, shallower and smaller anterior segments but only the mean ACD value of right eyes was found significantly less than those of the controls (p = 0.047). The mean ACD values of SSc subgroup patients with moderate to severe eyelid thickening (50 %) had lower ACD measurements compared to those of control group. (p = 0.043 for the right eyes, p = 0.070 for the left eyes). However, SSc subgroup patients with none to mild eyelid thickening (50 %) had similar anterior segment parameters with control subjects (p > 0.05). Anterior chamber parameters of the SSc patients could show significant differences. These differences occur parallel to the eyelid changes but not secondary to it. PMID:26694912

    Background Measurement of anterior segment parameters plays an important role in diagnosis and treatment of glaucoma. The objective of this study was to evaluate the repeatability and reproducibility of anterior chamber volume (ACV) measurements with rotating scheimpflug camera (RSC) and to examine agreement with anterior segment optical coherence tomography (AS-OCT). Methods Thirty nine healthy normal subjects were recruited from the Eye Center of Tongren Hospital. ACV was measured using RSC and AS-OCT in a randomly selected eye for each subject. For RSC measurements, both automatic and manual ACV measurements and 2 independent operators' ACV measurements were obtained. All subjects were invited for 3 visits within a week to evaluate repeatability and reproducibility of ACV measurement by RSC. Agreement was evaluated between RSC and AS-OCT. Results Good repeatability and reproducibility were found for both automatic and manual ACV measurements obtained by RSC. For intrasession repeatability, coefficient of variation (CVw) and intraclass correlation coefficient (ICC) values for automatic were 3.52% and 0.98; the values for manual were 3.44% and 0.97, respectively. For intersession reproducibility, the respective CVw and ICC values were 3.96% and 0.96. Good agreement was also found in 2 operators for both automatic and manual ACV measurements; nevertheless, poor agreement was found between RSC and AS-OCT (95% confidence interval (CI) for agreement of automatic RSC measurement versus AS-OCT were -96.3 to 72.8 μl and 95% CI for agreement of manual RSC measurement versus AS-OCT were between -41.7 to 10.1 μl). Conclusions Both RSC automatic and manual ACV measurements showed good repeatability and reproducibility, and showed comparable agreement between 2 independent operators, but poor agreement was found between RSC and AS-OCT.

    Full Text Available Anterior palatal fistulae or residual anterior clefts are a frequent problem following palatoplasty. Various techniques have been used to repair such fistulae, each having its own advantages and disadvantages. We have successfully used orbicularis oris musculomucosal flap to close anterior fistula and residual clefts in 25 patients. This study shows the superiority of this flap over other techniques because of its reliable blood supply, easy elevation and transfer to fistula site and finally because it is a single-stage procedure.

In this report, we describe a case of anterior mediastinal lymphnode TB seen as huge mass (7 cm on computed tomography (CT thorax without respiratory or food pipe compromise despite anterior mediastinum being an enclosed space. CT guided biopsy of the mass cultured Mycobacterium TB complex which was resistant to isoniazide, rifampicin, streptomycin ofloxacin, moxifloxacin, and pyrazinamide. Hence, we report primary multi drug resistant TB presenting as anterior mediastinal mass as a rare case report.

    Full Text Available A 29-year-old woman who underwent laser in situ keratomileusis (LASIK for myopic astigmatism in both eyes presented with severe pain, photophobia and decreased visual acuity in the left eye eight days after surgery. Examination revealed severe anterior uveitis with fibrinous exudates in the anterior chamber, flap edema and epithelial bullae. Laboratory investigations for uveitis were negative and the patient required systemic and intensive topical steroids with cycloplegics to control the inflammation. This case demonstrates that severe anterior uveitis may develop after LASIK and needs prompt and vigorous management for resolution.

    Full Text Available El objetivo de este estudio descriptivo fue estudiar la relación entre autoeficacia, desesperanza aprendida e incapacidad funcional en pacientes con diagnóstico de artritis reumatoide y así determinar el papel de los factores psicológicos en la adaptación del paciente a la enfermedad. Se aplicó el Cuestionarios de Actividades de la Vida Diaria, el Indice de Actitudes Reumatoides y la Escala de Autoeficacia para la Artritis a 79 pacientes en tratamiento en la unidad de reumatología de la Clínica Bolivariana de Medellín (Colombia. Se encontró que la autoeficacia percibida se asocia negativamente con la desesperanza, el dolor y la incapacidad funcional. A su vez, estas tres variables se relacionaron entre sí de forma positiva. De lo anterior se puede concluir que una adecuada autoeficacia permitiría asumir de manera más favorable la enfermedad y adaptarse a los cambios que ella conlleva. La desesperanza se asoció de manera significativa con el dolor, y éste con la incapacidad, por lo que se puede inferir, una relación indirecta con la desesperanza. Los resultados confirman el peso significativo que tienen las variables psicológicas estudiadas sobre la artritis reumatoide y que tenerlas en cuenta podría modificar potencialmente la experiencia de la enfermedad.

  18. Multimodal emotion perception after anterior temporal lobectomy

    Full Text Available In the context of emotion information processing, several studies have demonstrated the involvement of the amygdala in emotion perception, for unimodal and multimodal stimuli. However, it seems that not only the amygdala, but several regions around it, may also play a major role in multimodal emotional integration. In order to investigate the contribution of these regions to multimodal emotion perception, five patients who had undergone unilateral anterior temporal lobe resection were exposed to both unimodal (vocal or visual and audiovisual emotional and neutral stimuli. In a classic paradigm, participants were asked to rate the emotional intensity of angry, fearful, joyful, and neutral stimuli on visual analog scales. Compared with matched controls, patients exhibited impaired categorization of joyful expressions, whether the stimuli were auditory, visual, or audiovisual. Patients confused joyful faces with neutral faces, and joyful prosody with surprise. In the case of fear, unlike matched controls, patients provided lower intensity ratings for visual stimuli than for vocal and audiovisual ones. Fearful faces were frequently confused with surprised ones. When we controlled for lesion size, we no longer observed any overall difference between patients and controls in their ratings of emotional intensity on the target scales. Lesion size had the greatest effect on intensity perceptions and accuracy in the visual modality, irrespective of the type of emotion. These new findings suggest that a damaged amygdala, or a disrupted bundle between the amygdala and the ventral part of the occipital lobe, has a greater impact on emotion perception in the visual modality than it does in either the vocal or audiovisual one. We can surmise that patients are able to use the auditory information contained in multimodal stimuli to compensate for difficulty processing visually conveyed emotion.

    Full Text Available Dirofilariasis is a parasitic infection of the carvivores that may present as a zoonotic infestation in humans. Systemic involvement in man is subcutaneous, pulmonary, or ocular. We report a rare occurrence of ocular dirofilariasis in a 25-year-old male patient who presented with pain and redness in the eye. A live, white, coiled, and highly motile worm was present in the anterior chamber. The worm, however, could not be detected in the anterior chamber, posterior segment, or the angle of the anterior chamber when the patient was taken to the operating room for surgical removal of the worm. The patient was made to lie prone till the worm reappeared in the anterior chamber and was removed by paracentesis. The worm was identified as Dirofilaria repens on the basis of microscopic and histopathological examination.

    2016-01-01

    The rehabilitation of an unesthetic smile in the anterior maxilla is always a clinical challenge, especially when an improper shape and size, old restorations, and unesthetic shading are present. In addition, an irregular gingival zenith contour in the anterior maxilla can affect the smile's harmony. Thus, detailed treatment planning is needed to define a functional and esthetic prosthetic rehabilitation. This study describes a clinical case in which a 55-year-old woman was rehabilitated using Digital Smile Design planning and full ceramic crowns (metal free) in the anterior zone of the maxilla and mandible. To normalize the gingival zenith, a dynamic compression technique was performed using provisional restorations to condition the gingival tissues and harmonize the proportional length of the anterior upper teeth.

    Blepharoptosis is a condition of inadequate upper eyelid position, with a downward displacement of the upper eyelid margin resulting in obstruction of the superior visual field. Levator resection is an effective technique that is routinely used to correct aponeurotic ptosis. The anterior levator resection is the procedure of choice in moderate blepharoptosis when there is moderate to good levator muscle function, furthermore, with an anterior approach, a greater resection can be achieved than by a conjunctival approach. The authors describe a modification in the Putterman technique with a resection done over a plicated elevator, plication that was suggested by Mustardè. The technique has been named as elevator muscle anterior resection. The elevator muscle anterior resection inspires from the Fasanella-Servat operation by the use of a clamp, making the operation simple and predictable. PMID:26703054

    Full Text Available A 54-year-old male patient presented with acute myocardial infarction involving left anterior descending and right coronary artery territories. Coronary angiogram showed a single coronary artery with right coronary artery arising from left anterior descending artery (LAD, which coursed anterior to right ventricular outflow tract and thrombotic lesion in mid left anterior descending artery before origin of right coronary artery. The patient was treated with thrombolytic therapy and glycoprotein IIb/IIIa inhibitors. Anomalous origin of right coronary artery as a branch of LAD is a very rare type of congenital coronary artery anomalies. It is important to recognize this anomaly as it can be associated with extensive myocardial ischemia and sudden cardiac death in young persons even without atherosclerosis.

  9. Minimally invasive surgery of the anterior skull base: transorbital approaches

    Science.gov (United States)

    Gassner, Holger G.; Schwan, Franziska; Schebesch, Karl-Michael

    2016-01-01

    Minimally invasive approaches are becoming increasingly popular to access the anterior skull base. With interdisciplinary cooperation, in particular endonasal endoscopic approaches have seen an impressive expansion of indications over the past decades. The more recently described transorbital approaches represent minimally invasive alternatives with a differing spectrum of access corridors. The purpose of the present paper is to discuss transorbital approaches to the anterior skull base in the light of the current literature. The transorbital approaches allow excellent exposure of areas that are difficult to reach like the anterior and posterior wall of the frontal sinus; working angles may be more favorable and the paranasal sinus system can be preserved while exposing the skull base. Because of their minimal morbidity and the cosmetically excellent results, the transorbital approaches represent an important addition to established endonasal endoscopic and open approaches to the anterior skull base. Their execution requires an interdisciplinary team approach. PMID:27453759

  11. Examination of the sprained ankle: Anterior drawer test or arthrography?

    International Nuclear Information System (INIS)

    The accuracy of the anterior drawer test for the diagnosis of recent lateral ligament tears in the ankle was evaluated in a series of 192 patients using surgical or arthrographic findings for reference. Considerable overlapping of results was obtained in ankles with and without ligament tear. Twenty-eight per cent of the anterior talofibular ligament tears, and 38% of the combined anterior talofibular and calcaneofibular tears were not detected, and single and combined tears could not be differentiated. It is concluded that the anterior drawer test is too unreliable as a basis for any decision regarding surgical treatment of a recent sprain. Therefore, arthrography is recommended as the method of choice in such cases of recent ankle sprain, where the need of surgery has to be supported by X-ray analysis. (orig.)

  12. Case study: limitations of panoramic radiography in the anterior mandible.

    LENUS (Irish Health Repository)

    Walker, Cameron

    2009-12-01

    Dental Panoramic Tomography (DPT) is a widely used and valuable examination in dentistry. One area prone to artefacts and therefore misinterpretation is the anterior region of the mandible. This case study discusses a periapical radiolucency related to lower anterior teeth that is discovered to be a radiographic artefact. Possible causes of the artefact include a pronounced depression in the mental region of the mandible or superimposition of intervertebral spaces. Additional limitations of the DPT image include superimposition of radio-opaque structures, reduced image detail compared to intra-oral views and uneven magnification. These problems often make the DPT inappropriate for imaging the anterior mandible. Clinical Relevance: Panoramic radiography is often unsuitable for radiographic examination of the anterior mandible.

    Objective. To detect histological characteristic of anterior cruciate ligament (ACL) and medial collateral ligament (MCL). Methods. In each of 20 skeletally mature male mongrels and 4 men, the ACL and MCL were examined by standard hematoxylin-eosin procedure and toluidine blue staining for histologic observation. Results. The fibroblasts in medial collateral are elongated to spindle shape and aligned in a row between the bundles of collagenous fibers. Toluidine blue staining is negative. The anterior cruciate ligament demonstrated more heterogenous cell types and arrangement. It had three major cell forms:spindle, round and ovoid type, which were shorter but greater than the cells in medial collateral ligament. Toluidine blue staining was positive in anterior cruciate ligament. Most cells in anterior cruciate ligament were enclosed within lacunae. Conclusion. This study suggests that the ACL has different histological characteristics from MCL, and is more cartilage-like in nature.

  1. Anticoagulation after anterior myocardial infarction and the risk of stroke.

    Directory of Open Access Journals (Sweden)

    Jacob A Udell

    Full Text Available BACKGROUND: Survivors of anterior MI are at increased risk for stroke with predilection to form ventricular thrombus. Commonly patients are discharged on dual antiplatelet therapy. Given the frequency of early coronary reperfusion and risk of bleeding, it remains uncertain whether anticoagulation offers additional utility. We examined the effectiveness of anticoagulation therapy for the prevention of stroke after anterior MI. METHODS AND FINDINGS: We performed a population-based cohort analysis of 10,383 patients who survived hospitalization for an acute MI in Ontario, Canada from April 1, 1999 to March 31, 2001. The primary outcome was four-year ischemic stroke rates compared between anterior and non-anterior MI patients. Risk factors for stroke were assessed by multivariate Cox proportional-hazards analysis. Warfarin use was determined at discharge and followed for 90 days among a subset of patients aged 66 and older (n = 1483. Among the 10,383 patients studied, 2,942 patients survived hospitalization for an anterior MI and 20% were discharged on anticoagulation therapy. Within 4 years, 169 patients (5.7% were admitted with an ischemic stroke, half of which occurred within 1-year post-MI. There was no significant difference in stroke rate between anterior and non-anterior MI patients. The use of warfarin up to 90 days was not associated with stroke protection after anterior MI (hazard ratio [HR], 0.68; 95% confidence interval [CI], 0.37-1.26. The use of angiotensin-converting-enzyme inhibitors (HR, 0.65; 95% CI, 0.44-0.95 and beta-blockers (HR, 0.60; 95% CI, 0.41-0.87 were associated with a significant decrease in stroke risk. There was no significant difference in bleeding-related hospitalizations in patients who used warfarin for up to 90 days post-MI. CONCLUSION: Many practitioners still consider a large anterior-wall MI as high risk for potential LV thrombus formation and stroke. Among a cohort of elderly patients who survived an anterior

    The objective was to evaluate the association, by MRI, of anterior calcaneal process fractures with tarsal coalitions, ankle sprains, and bifurcate ligament abnormalities. A retrospective review of 1,479 foot and ankle MR images was performed, over a period of 5 years, for isolated anterior process fractures of the calcaneus. Fifteen 1.5-T MR examinations were systematically evaluated by two radiologists in consensus. Marrow edema patterns, presence of a calcaneonavicular coalition, as well as bifurcate and anterior talofibular ligaments, were evaluated. There were 15 fractures of the anterior calcaneal process with an incidence of 1%. The average patient age was 51 years (range 25-82). Twelve patients were women and 3 were men. The majority of the fractures (14 out of 15) presented as an edema pattern on T2-weighted images, either diffuse (9 out of 15), or vertical (5 out of 15). One case did not show marrow edema, but rather a hypointense line. Nine patients (60%) demonstrated calcaneonavicular coalition and anterior calcaneal process fracture. In 6 patients (50%) the anterior talofibular ligament (ATFL) was thickened. Three patients did not have axial images, and were classified as non-conclusive for the ATFL evaluation. The bifurcate ligament was thickened with hyperintense signal demonstrating a sprain in 9 out of 13 (69%). Only 2 patients (16.5%) had an anterior calcaneal process fracture without any associated abnormality. We believe that there is a probable association of anterior process fractures and calcaneonavicular coalitions. We also feel, based on our results and the prior literature that there is likely also an association with both ATFL injuries and bifurcate ligament injuries. (orig.)

We also feel, based on our results and the prior literature that there is likely also an association with both ATFL injuries and bifurcate ligament injuries. (orig.)

    2014-01-01

    Conclusions: The novel finding of an asymmetry in morphology of the anterior visual system following long-term survival from early monocular enucleation indicates altered postnatal visual development. Possible mechanisms behind this altered development include recruitment of deafferented cells by crossing nasal fibres and/or geniculate cell retention via feedback from primary visual cortex. These data highlight the importance of balanced binocular input during postnatal maturation for typical anterior visual system morphology.

    For decades spinal surgeons have attempted to design simple, single stage anterior internal fixation systems for the thoracic and lumbar spine. Early devices presented both biomechanical and technical problems. The AO Anterior Thoracolumbar Locking Plate (ATLP) was designed to solve some of the problems encountered with early anterior instrumentation. The ATLP system is constructed in Commercially Pure titanium. It is a low profile device indicated for use for unstable burst fractures in the anterior column; metastatic tumor management; and degenerative diseases of the thoracolumbar spine between levels T10 and L5. Implantation of the device involves direct anterior decompression with sagittal reduction and corpectomy. This is followed by grafting reconstruction, and plate fixation. This device has been implanted in 25 patients with an average follow-up of 38 months. There were five (5) broken screws in three (3) patients, and no broken plates. Implant related postoperative complications included two misplaced screws. Preliminary results indicate that the ATLP system seems to be a safe, low profile, MRI/CT compatible device that provides definitive single stage fixation of the anterior spinal column. PMID:9160452

    Purpose: We tried to find out the relevance of anterior mandibular body ostectomy in deformities of the mandible specially prognathism, which is primarily limited to anterior part only. Patients and Methods: Ten patients with skeletal deformity along with malocclusion, which was limited to anterior body of mandible were selected. Selected patients had proper molar interdigitation (even if class 3) and in general had anterior crossbite (except one). All patients had crossed their growth spurts and had no hormonal influence on facial deformity. Specific protocol, including cephelometric analysis cephalometry for orthognathic surgery, prediction tracing and model surgeries were devised. Pre and post-surgical orthodontics and body ostectomy were performed in all patients along with 18-month post-op follow-up. Results: There was significant reduction in prognathism and horizontal dysplasia in all ten patients. Anterior crossbite as well as axis of incisiors over mandibular plane was corrected in all patients due to decrease in length of mandibular body. All patients showed decreased facial height and better lip competence with intact posterior occlusion and no (negligible or transient) sensory loss. Conclusions: Our study could confirm that people whose deformity is limited to the anterior part of mandible with reasonable occlusion posteriorly can get satisfactory cosmetic and functional results through body ostectomy alone rather than going for surgical procedure in the ramal area, which is liable to cause sensory and occlusal disturbances.

  3. Anterior, posterior, left anterior oblique, and geometric mean views in gastric emptying studies using a glucose solution

    International Nuclear Information System (INIS)

    Previous research has shown that the single anterior view of the stomach overestimates the gastric half-emptying time of a solid meal compared to the geometric mean of the anterior and posterior views. Little research has been performed comparing the various views of gastric emptying of a glucose solution. After an overnight fast, 49 nondiabetic subjects were given a 450 ml solution containing 50 g of glucose and 200 μCi of technetium-99m sulfur colloid. Sequential 1-min anterior, posterior, and left anterior oblique views were obtained every 15 min. The mean percent solution remaining in the stomach for all three views differed from the geometric mean by 1.9% or less at all time points. Average gastric half-emptying times were: geometric mean, 62.7±3.3 min; anterior, 61.9±3.2 min; posterior, 63.5±3.5 min; and left anterior oblique, 61.6±3.3 min. These half-emptying times were not statistically different. For individual patients, differences between all three views and the geometric mean were not clinically important. Approximately 95% of all patients are expected to have gastric half-emptying times measured by any of the three single views within 17 min of the gastric half-emptying time obtained using the geometric mean. The imaging of gastric emptying using glucose solutions can be performed using a convenient single view which allows continuous dynamic imaging. (orig.)

    Anteriorly displaced anus is an anomaly that is debated with regard to its nomenclature, diagnosis and management. To describe MRI anatomy of the anal canal in children with anteriorly displaced anus and its impact on the process of defecation. We prospectively examined ten children (7 girls, 3 boys; age range 7 months to 8 years, mean 3 years) with anteriorly displaced anus between August 2009 and April 2012. Noncontrast MRI examinations were performed on a 1.5-T magnet. T1- and T2-weighted turbo spin-echo images were acquired in axial, sagittal and coronal planes of the pelvis. The anorectal angle and the relative hiatal distance were measured in mid-sagittal images, and compared with those of a control group using the Mann-Whitney test. In children with anteriorly displaced anus, no anatomical abnormality was depicted at the level of the proximal anal canal. However, the distal anal canal was displaced anteriorly, running out its external muscle cuff, which remained un-displaced at the usual site of the anus. This changes the orientation of the central axis of the anal canal by passing across instead of along the fibers of the longitudinal muscle coat. Children with anteriorly displaced anus had a more obtuse anorectal angle (mean 112.1 ), which was significantly greater than that of the control group (mean 86.2 ). MRI is a valuable tool in studying the anatomy of the anal canal in children with anteriorly displaced anus. The abnormal orientation of the longitudinal muscle across the anal canal can explain the obstructed defecation in these children. Based on this study, it might be of interest to use MRI in studying equivocal cases and children with unexplained constipation. (orig.)

    2016-01-01

    A routine eye examination of a 69-year-old man revealed a scleral perforation of one of the haptics of the anterior chamber intraocular lens (AC IOL) which had been implanted many years ago. The patient was asymptomatic with good visual acuity. His history was negative for any trauma, eye rubbing, topical corticosteroid use, or autoimmune disease. The horizontal and vertical white-to-white diameters of the cornea in the right eye were 11.5 and 10.5 mm, respectively. Anterior segment optical coherence tomography showed the anterior chamber length to be 12.28 mm horizontally and 10.63 mm vertically. The patient underwent an IOL exchange, and the length of the explanted AC IOL was measured to be 12 mm. We speculate that the AC IOL, which was vertically aligned, was oversized. This case demonstrates the need for proper sizing and positioning of an AC IOL. In complex cases where AC IOL may be used, measuring the horizontal and vertical lengths of the anterior chamber by anterior segment optical coherence tomography prior to surgery may be useful.

    A retrospective study was performed on patients who underwent myringoplasty for either anterior or subtotal perforations over an 8-year period (from 1994 till 2004). We used the KTP-laser assisted anterior anchoring technique combining with anterior "pull-back" method. Patients' ages ranged from 6-62 years (median 36.5). The mean follow-up period was 2.8 years (minimum 6 months). The audiological results were analysed with the "Pytel software", which was developed in our department. As for the procedure, the drum remnant was freed from the malleus handle with the use of the laser and elevated out of it's sulcus anterior-superiorly. Large fascia graft was fashioned with a split of 4-5 mm in the middle of one edge. The graft was placed using the underlay technique medial to the handle of the malleus. A pull-back tunnel was created at the border of the anterior quadrants to further facilitate the survival of the graft. In this series the graft taking rate was 100%. Reperforation due to an undersized fascia was observed in one case. Post-operative audiological results indicated no bone conduction threshold elevation in any frequencies. Using the laser, cochlear trauma can be prevented, double fixation of the drum prevents lateralisation and blunting. Wide canalplasty makes both the approach and the follow-up very easy. Thorough soft tissue and bone work is advantageous from the fascia taking rate point of view.

  17. Association of Cryptogenic Organizing Pneumonia in Bilateral Anterior Uveitis

    2014-11-01

    Full Text Available Two female patients with histories of cancer who showed cryptogenic organizing pneumonia (COP complications and bilateral anterior uveitis with hypopyon were examined. Both patients had suffered from COP and received intermitted systemic corticosteroid administration (SCA. The first patient, a 65-year-old woman with a history of breast cancer, showed bilateral uveitis with hypopyon. The topical corticosteroid treatment was ineffective. After SCA for the treatment of COP was started, the hypopyon gradually dissipated. Upon termination of SCA, uveitis relapses were controlled by renewed SCA. The other patient, a 69-year-old woman with a history of ovarian cancer, showed bilateral anterior uveitis with hypopyon. Her intraocular outcome did not improve by the topical corticosteroid administration, but SCA that was applied to treat COP led to remission of uveitis. Imaging examinations, biochemical analysis, symptoms or HLA-B27 antigen screenings in either patient did not explain the development of uveitis. Bilateral anterior uveitis is commonly related to autoimmune disease or systemic syndrome. We report two cases with COP that developed bilateral anterior uveitis with hypopyon resistant to topical administration but responsive to systemic administration of corticosteroid. These findings suggest that COP can be associated with the etiology of anterior uveitis.

    2016-08-01

    Acute anterior uveitis (AAU) is the commonest type of uveitis and HLA-B27 AAU is the most frequently recognized type of acute anterior uveitis and anterior uveitis overall. Recent evidence indicates that acute anterior uveitis is a heterogenous disease, is polygenic and is frequently associated with the spondyloarthropathies (SpA). Studies of patients with AAU and animal models of disease indicate a role for innate immunity, the IL-23 cytokine pathway and exogenous factors, in the pathogenesis of both SpA and acute anterior uveitis. Recently described genetic associations cluster around immunologic pathways, including the IL-17 and IL-23 pathways, antigen processing and presentation, and lymphocyte development and activation. Patients with ankylosing spondylitis (AS) and AAU share other genetic markers, such as ERAP-1, which show strong evidence of gene-gene interaction and point to new mechanisms of disease pathogenesis. These observations have major implications for understanding the pathogenesis of HLA-B27 diseases, such as AAU, and may lead to the development of more specific therapy for AAU.

  19. Ophthalmohelioses and peripheral light focusing by the anterior eye

    1994-07-01

    A coincidence of the locations of foci of scattered light in the anterior eye with the usual locations of common sun-related eye conditions has been observed. These phenomena may explain the pathogenesis of pterygium and the initial location of certain cortical lens opacities and eyelid malignancies. Human and bovine eyes were used to demonstrate that the anterior eye acts as a side-on lens system. Light incident at the temporal limbus can be concentrated at the nasal limbus or beyond or at the nasal crystalline lens equator. The main pathways of light are transcameral and this is demonstrated by the use of baffles. Although this phenomenon is obvious with visible light, focusing of light at 308nm can be demonstrated. Computer-assisted optical ray tracing in a standard human anterior segment model showed that the peak intensity at the distal limbus is approximately twenty times that of the incident light intensity. The degree of limbal focusing is determined by corneal shape and anterior chamber depth. Such light focusing may be particularly injurious to corneal and lenticular epithelial stem cells. These observations provide circumstantial evidence that peripheral refraction phenomena are involved in the pathogenesis of the anterior ophthalmohelioses. Adequate lateral protection of the eye from increasing ultraviolet insolation may be prudent.

    2015-08-01

    Recovery following anterior cruciate ligament reconstruction is an arduous process that requires a significant mental and physical commitment to rehabilitation. Orthopaedic research in recent years has focused on optimizing anterior cruciate ligament surgical techniques; however, despite stable anterior cruciate ligament reconstructions, many athletes still never achieve their preinjury ability or even return to sport. Psychological factors associated with patient perceptions and functional outcomes following anterior cruciate ligament reconstruction are important to acknowledge and understand. Issues related to emotional disturbance, motivation, self-esteem, locus of control, and self-efficacy can have profound effects on patients' compliance, athletic identity, and readiness to return to sport. The psychological aspects of recovery play a critical role in functional outcomes, and a better understanding of these concepts is essential to optimize the treatment of patients undergoing anterior cruciate ligament reconstruction, particularly those who plan to return to sport. Identifying at-risk patients, encouraging a multidisciplinary approach to patient care, and providing early referral to a sports psychologist may improve patient outcomes and increase return-to-play rates among athletes.

    Purpose. To evaluate anterior segment's structures by Pentacam in patients with tilted disc syndrome (TDS). Methods. Group 1 included forty-six eyes of forty-six patients who have the TDS. Group 2 including forty-six eyes of forty-six cases was the control group which was equal to the study group in age, gender, and refraction. A complete ophthalmic examination was performed in both groups. All cases were evaluated by Pentacam. The axial length (AL) of eyes was measured by ultrasound. Quantitative data obtained from these measurements were compared between two groups. Results. There was no statistically significant difference for age, gender, axial length, and spherical equivalent measurements between two groups (p = 0.625, p = 0.830, p = 0.234, and p = 0.850). There was a statistically significant difference for central corneal thickness (CCT), corneal volume (CV), anterior chamber angle (ACA), and pupil size measurements between two groups (p = 0.001, p = 0.0001, p = 0.003, and p = 0.001). Also, there was no statistically significant difference for anterior chamber depth (ACD), anterior chamber volume (ACV), and lens thickness (LT) measurements between two groups (p = 0.130, p = 0.910, and p = 0.057). Conclusion. We determined that CCT was thinner, CV was less, and ACA was narrower in patients with TDS. There are some changes in the anterior segment of the eyes with tilted disc. PMID:27648303

    The main aim of this research is finding the feature vectors of the anterior and posterior cruciate ligaments (ACL and PCL). These feature vectors have to clearly define the ligaments structure and make it easier to diagnose them. Extraction of feature vectors is obtained by analysis of both anterior and posterior cruciate ligaments. This procedure is performed after the extraction process of both ligaments. In the first stage in order to reduce the area of analysis a region of interest including cruciate ligaments (CL) is outlined in order to reduce the area of analysis. In this case, the fuzzy C-means algorithm with median modification helping to reduce blurred edges has been implemented. After finding the region of interest (ROI), the fuzzy connectedness procedure is performed. This procedure permits to extract the anterior and posterior cruciate ligament structures. In the last stage, on the basis of the extracted anterior and posterior cruciate ligament structures, 3-dimensional models of the anterior and posterior cruciate ligament are built and the feature vectors created. This methodology has been implemented in MATLAB and tested on clinical T1-weighted magnetic resonance imaging (MRI) slices of the knee joint. The 3D display is based on the Visualization Toolkit (VTK).

    No study reports the histological features of the various zone of the anterior tubercle of the tibia in the different stages of the Osgood-Schlatter (O-S) lesion. For this reason we carried on an histological study. Specimens were taken from 13 patients with O-S lesion prior to surgery. In 4 cases in the apophyseal stage lesions were present in an altered fibrocartilage anterior to the ossification centre. In 9 cases in the epiphyseal stage varying degrees of reparative tissues were observed in the bed of the fragment of the secondary ossification centre. In 3 of them a zone of lesion was observed within the fibrocartilage anterior to the ossification centre. These results suggest that the slippage of the patellar tendon insertion may be progressive and caused by pathological fibrocartilage. PMID:21669134

    During the first step of cataract surgery, the lens capsule is perforated and a circular hole is created with a sharp instrument, a procedure called capsulorhexis. To develop automated systems that can assist ophthalmologists during capsulorhexis, the forces required must be quantified. This study investigates perforation forces of the central anterior lens capsule in porcine eyes, which are used as a conservative model for the human eye. A micro-mechanical characterisation method is presented that measures capsular bag perforation forces with a high precision positioning and high-resolution force sensing system. The force during perforation of the anterior lens capsule was measured with various sized needles and indentation speeds and is found to be 15-35mN. A bio-mechanical model is identified that describes an exponential correlation between indentation force and depth, indicating strain hardening behaviour of the porcine anterior lens capsule.

    Anterior megalophthalmos (AM) is an uncommon developmental anomaly of the anterior segment of the eye with a constellation of findings that includes enlarged cornea,deep anterior chamber,posterior positioning of the iris and lens,iris stroma atrophy,hypoplasia of iris dilator,pupil displacement,large capsular bag,lens subluxation,prematurely cataract and the tendency to retinal detachment.AM,especially when symptoms are mild,is not an easy disease to diagnose.We present 3 AM cases that were misdiagnosed as congenital cataract with weak zonule and megalocornea.Intraocular lenses (IOLs) dislocated after standard cataract surgeries and subsequent surgery (replacing the dislocated IOLs with iris-claw intraocular lenses) achieved satisfactory outcome.Although rare,AM should be included in the differential diagnosis of enlarged cornea and we recommend implanting Artisan lens in AM patients.

    Compartment syndrome rarely follows anterior cruciate ligament reconstruction. However, when it does, it may result in mononeuropathies that are amenable to neurolysis. The authors of this study present an 18-yr-old woman who sustained a right anterior cruciate ligament tear and underwent uneventful anterior cruciate ligament reconstruction using femoral and popliteal nerve blocks. Postoperatively, she developed compartment syndrome requiring emergent fasciotomies. At 11 wks after fasciotomy, results of electrophysiologic tests showed evidence of severe fibular and tibial neuropathies. Magnetic resonance images showed extensive tricompartmental myonecrosis. Fibular and tibial neurolysis as well as decompression were performed, followed by intensive outpatient rehabilitation. At the 6-mo follow-up, she reported resolution of pain as well as significant improvement in sensation, strength, and function. Early recognition and intervention are crucial to prevent serious neurologic damage. Excessive tourniquet pressure and anesthetic nerve blocks may have been responsible.

    Full Text Available Objective To study the clinical manifestations, pathologic features, diagnosis, treatment and prognosis of primary synovial sarcoma in the anterior mediastinum. Methods A case of primary synovial sarcoma in the anterior mediastinum was reported. Clinical features, imaging manifestations, pathology features and therapeutic effect were analysed and the relevant literature was reviewed. Results A 48-year-male patient was admitted with complaint of right chest pain for 4 days. Chest computerized tomography revealed a large mass located at the right anterior mediastinum, and it was primarily diagnosed as invasive thymoma. Pathological examination by CT-guided percutaneous needle biopsy manifested that, under microscope, the tumor cells were short and spindle in shape forming a nest structure, suggested it was a thymoma. The patient then underwent resection of thymoma with removal of fat and connective tissue in the anterior mediastinum. During the operation the size of the tumor was 15cm×15cm×10cm, being located at the anterior mediastinum, and it tended to bleed. The diagnosis of primary monophasic synovial sarcoma in the mediastinum was confirmed by postoperative/pathology examination. Immunohistochemistry staining showed that the tumor cells were positive for the markers Bcl-2 and EMA, but negative for the markers CK (pan and S100. The patient suffered from local recurrence with metastases to lung 4 months after surgery. The patient received 2 chemotherapeutic courses with ifosfamide, epirubicin and cisplatin. He died 6 months after surgery. Conclusion Primary synovial sarcoma in the anterior mediastinum is an extremely rare and highly malignant tumor with poor prognosis. The diagnosis depends on the pathological features, immunohistochemistry and RT-PCR. Radical resection combined with comprehensive treatment may improve the survival rate.

    Objective: To evaluate the safety and efficacy of new modality of anterior skull base repair,namely sandwich-like reconstruction of anterior skull base defects. Methods: A retrospective analysis of patients who underwent transcranial or transcranial-facial resections of malignant or benign aggressive tumors involving the anterior skull base was conducted in our department. We used the sandwich-like reconstruction, using pedicled pericranial flap, frontal muscle flap and free abdominal adipose tissue between them, to separate of cranial cavity and aerodigest tract and keep the frontal lobes in place following resections of anterior skull base tumors. Results: From October, 1984 to October, 1998, 116 patients underwent transcranial or transcranialfacial approach for the resection of malignant or aggressive benign tumor, and sandwich-like repairs were performed for the anterior skull base defect. 54 (46.6 % ) patients had previous operation, with a maximum of 5 surgeries. The average age of patients was 35.9 years old, ranging form 6 to 73 years old. Forty-eight (41.4%)patients had malignant neoplasmas, and sixty-eight (58.6%) patients had benign aggressive tumors. In our series, with the maximal follow-ups for as long as 14 years, NO one had early failure of the one-stage reconstruction. CSF fluid leakage was not encountered, nor was ascending bacterial meningitis observed. No immediate or delayed prolapse of dura or frontal lobes was observed. Conclusion: We conclude that the sandwich-like reconstruction, using pericranial flap, frontal muscle flap and free abdominal adipose between them, is an extremely safe and effective procedure for the repair of skull base defect, even when tumor extensively involves anterior skull base.

    Full Text Available Background/Aim. An important element of prosthetic treatment of edentulous patients is selecting the size of anterior artificial teeth that will restore the natural harmony of one’s dentolabial structure as well as the whole face. The main objective of this study was to determine the correlation between the inner canthal distance (ICD and interalar width (IAW on one side and the width of both central incisors (CIW, the width of central and lateral incisors (CLIW, the width of anterior teeth (ATW, the width between the canine cusps (CCW, which may be useful in clinical practice. Methods. A total of 89 subjects comprising 23 male and 66 female were studied. Their age ranged from 19 to 34 years with the mean of 25 years. Only the subjects with the preserved natural dentition were included in the sample. All facial and intraoral tooth measurements were made with a Boley Gauge (Buffalo Dental Manufacturing Co., Brooklyn NY, USA having a resolution of 0.1mm. Results. A moderate correlation was established between the interalar width and combined width of anterior teeth and canine cusp width (r = 0.439, r = 0.374. A low correlation was established between the inner canthal distance and the width of anterior teeth and canine cusp width (r = 0.335, r = 0.303. The differences between the two genders were highly significant for all the parameters (p < 0.01. The measured facial distances and width of anterior teeth were higher in men than in women. Conclusion. The results of this study suggest that the examined interalar width and inner canthal distance cannot be considered reliable guidelines in the selection of artificial upper anterior teeth. However, they may be used as a useful additional factor combined with other methods for objective tooth selection. The final decision should be made while working on dentures fitting models with the patient’s consent.

    Introduction Gonioscopy is the gold standard in assessing anterior chamber angles. However, interobserver variations are common and there is a need for reliable objective method of assessment. Aim To compare the anterior chamber angle by gonioscopy and Spectral Domain Optical Coherence Tomography (SD-OCT) in individuals with shallow anterior chamber. Materials and Methods This comparative observational study was conducted in a rural tertiary multi-speciality teaching hospital. A total of 101 eyes of 54 patients with shallow anterior chamber on slit lamp evaluation were included. Anterior chamber angle was graded by gonioscopy using the shaffer grading system. Angles were also assessed by SD-OCT with Trabecular Iris Angle (TIA) and Angle Opening Distance (AOD). Chi-square test, sensitivity, specificity, positive and negative predictive value to find correlation between OCT parameters and gonioscopy grading. Results Females represented 72.7%. The mean age was 53.93 ±8.24 years and mean anterior chamber depth was 2.47 ± 0.152 mm. Shaffer grade ≤ 2 were identified in 95(94%) superior, 42(41.5%) inferior, 65(64.3%) nasal and 57(56.4%) temporal quadrants. Cut-off values of TIA ≤ 22° and AOD ≤ 290 μm were taken as narrow angles on SD-OCT. TIA of ≤ 22° were found in 88(92.6%) nasal and 87(87%) temporal angles. AOD of ≤ 290 μm was found in 73(76.8%) nasal and 83(83%) temporal quadrants. Sensitivity in detecting narrow angles was 90.7% and 82.2% for TIA and AOD, while specificity was 11.7% and 23.4%, respectively. Conclusion Individuals were found to have narrow angles more with SD-OCT. Sensitivity was high and specificity was low in detecting narrow angles compared to gonioscopy, making it an unreliable tool for screening. PMID:27190851

    Full Text Available ABSTRACT Purpose: To evaluate the difference in terms of refractive errors and anterior segment parameters between schizophrenic patients and healthy volunteers. Methods: This study compared 70 patients (48 men who were diagnosed with schizophrenia with a control group of 60 (35 men who were similar in terms of age, gender, education, and socioeconomic level. Anterior segment examination was performed using a Scheimflug system. Axial length and lens thickness (LT were measured using optic biometry. The following tests were administered to the psychiatric patient group: Brief Psychiatric Rating Scale (BPRS, Scale for the Assessment of Negative Symptoms (SANS, and Scale for the Assessment of Positive Symptoms (SAPS. Results: Mild myopia was detected in both the schizophrenic and control groups, with no statistically significant difference (p>0.005. Corneal volume (CV, anterior chamber volume (ACV, anterior chamber depth (ACD, and central corneal thickness (CCT values were lower in the schizophrenic group, and there was a statistically significant between-group difference (p=0.026, p=0.014, p=0.048, and p=0.005, respectively. LT was greater in schizophrenics, and the difference was found to be statistically significant (p=0.006. A statistically significant negative correlation was found between SAPS and cylinder values (p=0.008. The axial eye length, cylinder value, pupil diameter, mean keratometric value, and anterior chamber angle revealed no statistically significant difference between the groups (p>0.05. Conclusion: No statistically significant difference was detected in terms of refraction disorders between schizophrenics and the healthy control group, while some differences in anterior chamber parameters were present. These results demonstrate that schizophrenics may exhibit clinical and structural differences in the eye.

    There is sparse information concerning approaches to metachronous lung cancer in patients who had a previous pneumonectomy for lung carcinoma. We describe the case of a 55-year-old woman who underwent a left pneumonectomy for lung carcinoma. Four years later, a radiological examination revealed a hypermetabolic nodule in the right upper lobe, which was located in the left hemithorax because of right lung hyperinflation and a mediastinal shift to the left. Wedge resection was carried out through a left anterior mediastinotomy. We believe that an anterior mediastinotomy represents a valuable option for the management of recurrent lung cancer after previous surgery. PMID:26124429

    We documented the spacing and distribution of perikymata on the buccal enamel surface of fossil hominin anterior teeth with reference to a sample of modern human and modern great ape teeth. A sample of 27 anterior teeth attributed to Australopithecus (5 to A. afarensis, 22 to A. africanus) and of 33 attributed to Paranthropus (6 to P. boisei, and 27 to P. robustus) were replicated and sputter-coated with gold to enable reflected light microscopy of their surface topography. Anterior teeth were then divided into 10 equal divisions of buccal crown height. The total perikymata count in each division of crown height was recorded using a binocular microscope fitted with a vernier micrometer eyepiece. Then the mean number of perikymata per millimeter was calculated for each division. Similar comparative data for a modern sample of 115 unworn human anterior teeth and 30 African great ape anterior teeth were collected from ground sections. Perikymata counts in each taxon (together with either known or presumed periodicities of perikymata) were then used to estimate enamel formation times in each division of crown height, for all anterior tooth types combined. The distributions of these estimates of time taken to form each division of crown height follow the same trends as the actual perikymata counts and differ between taxa in the same basic way. The distinction between modern African great apes and fossil hominins is particularly clear. Finally, we calculated crown formation times for each anterior tooth type by summing cuspal and lateral enamel formation times. Estimates of average crown formation times in australopiths are shorter than those calculated for both modern human and African great ape anterior teeth. The data presented here provide a better basis for exploring differences in perikymata spacing and distribution among fossil hominins, and provide the first opportunity to describe four specimens attributed to Homo in this context. Preliminary data indicate that

    Injury to the axillary artery is a rare complication of anterior shoulder dislocation. Open surgical repair is technically demanding because of the anatomical position of the vessel and the propensity for concomitant injuries. Standard surgical exposure techniques involve extensive dissection, including a combination of supraclavicular or infraclavicular incision, median sternotomy, and thoracotomy causing significant morbidity and mortality rates. Endovascular techniques may offer an alternative to these surgically demanding procedures. We present a patient with a traumatic dissection of the axillary artery following anterior shoulder dislocation who was successfully managed with an endovascular stent. PMID:18411587

  6. Clearance from the anterior chamber of RBCs from human diabetics

    International Nuclear Information System (INIS)

    Erythrocytes from diabetic patients manifest decreased deformability and increased adherence. These abnormal membrane properties may diminish the ability of erythrocytes (RBCs) from diabetics to undergo deformation in passage through the trabecular meshwork. Using sodium chromate Cr 51-labeled RBCs from type I diabetic patients with proliferative retinopathy and normal control subjects, we studied RBC clearance from the rabbit anterior chamber. The mean time for 50% clearance (T50) of RBCs from diabetics (76 hours) was significantly longer than that for RBCs from normal subjects (19.5 hours). In this model, RBCs from diabetics have a slower clearance from the anterior chamber than do RBCs from normal subjects

    Full Text Available Injury to the anterior cruciate ligament (ACL not only causes mechanical instability but also leads to a functional deficit in the form of diminished proprioception of the knee joint. "Functional" recovery is often incomplete even after "anatomic" arthroscopic ACL reconstruction, as some patients with a clinically satisfactory repair and good ligament tension continue to complain of a feeling of instability and giving way, although the knee does not sublux on clinical testing. Factors that may play a role could be proprioceptive elements, as the intact ACL has been shown to have significant receptors. Significant data have come to light demonstrating proprioceptive differences between normal and injured knees, and often between injured and reconstructed knees. ACL remnants have been shown to have proprioceptive fibers that could enhance functional recovery if they adhere to or grow into the reconstructed ligament. Conventionally the torn remnants are shaved off from the knee before graft insertion; modern surgical techniques, with remnant sparing methods have shown better outcomes and functional recovery, and this could be an avenue for future research and development. This article analyzes and reviews our understanding of the sensory element of ACL deficiency, with specific reference to proprioception as an important component of functional knee stability. The types of mechanoreceptors, their distribution and presence in ACL remnants is reviewed, and suggestions are made to minimize soft tissue shaving during ACL reconstruction to ensure a better functional outcome in the reconstructed knee.

    The purpose of this work is the clinical commissioning of a recently developed in vivo range verification system (IRVS) for treatment of prostate cancer by anterior and anterior oblique proton beams. The IRVS is designed to perform a complete workflow for pre-treatment range verification and adjustment. It contains specifically designed dosimetry and electronic hardware and a specific software for workflow control with database connection to the treatment and imaging systems. An essential part of the IRVS system is an array of Si-diode detectors, designed to be mounted to the endorectal water balloon routinely used for prostate immobilization. The diodes can measure dose rate as function of time from which the water equivalent path length (WEPL) and the dose received are extracted. The former is used for pre-treatment beam range verification and correction, if necessary, while the latter is to monitor the dose delivered to patient rectum during the treatment and serves as an additional verification. The entire IRVS workflow was tested for anterior and 30 degree inclined proton beam in both solid water and anthropomorphic pelvic phantoms, with the measured WEPL and rectal doses compared to the treatment plan. Gafchromic films were also used for measurement of the rectal dose and compared to IRVS results. The WEPL measurement accuracy was in the order of 1 mm and after beam range correction, the dose received by the rectal wall were 1.6% and 0.4% from treatment planning, respectively, for the anterior and anterior oblique field. We believe the implementation of IRVS would make the treatment of prostate with anterior proton beams more accurate and reliable. PMID:27002470

Un técnico capacitado realizó las entrevistas mediante un cuestionario estándar diseñado por la Comisión Interamericana para el Control de Abuso de Drogas de la Organización de Estados Americanos (CICAD/OEA utilizado en varios países de América Latina. El cuestionario preguntó a los jóvenes acerca de su situación sociodemográfica, los períodos anteriores y actuales de detención, los antecedentes penales, los patrones de uso de varias categorías de drogas, edad de inicio, la presión social, la contención familiar, la percepción y el conocimiento y la información en relación con el consumo de drogas. Los jóvenes entrevistados reportaron mayor consumo de alcohol, tabaco y una variedad de drogas ilícitas y en la mayoría de ellos había una estrecha relación entre el consumo de drogas y el delito. Mientras que la relación entre el abuso de sustancias y la comisión del delito no es bien conocida, la evidencia disponible sugiere que el consumo de sustancias exacerba el delito y preceden a ello, debido a las condiciones sociales y económicas, así como otros factores de la familia/comunidad. Además, el estudio encuentra que los infractores tienden a comenzar a experimentar con sustancias a edades más tempranas, que los no infractores.

    Full Text Available OBJECTIVE: To evaluate the complications of anterior approach to the cervical spine in patients who underwent cervical arthrodesis with instrumentation. METHODS: Prospective and descriptive study was conducted from January 2009 to April 2010. All patients who underwent arthrodesis of the cervical spine by anterior approach were included, regardless the diagnosis. Access was made by the anterior approach on the right side. We evaluated the number of operated levels (1, 2 or 3 levels and, the type of procedure performed: discectomy and placement of cage and plate (D+C+P, discectomy with placement of a cage (D+C or corpectomy with placement of cage and plate (C+C+P. All complications related to surgical approach were reported. RESULTS: We studied 34 patients, 70% male. The average age was 50 years and mean follow-up was 8 months. Eighteen percent of patients had complications, distributed as follows: dysphasia (33% and dysphonic (67%. Among patients who developed complications, most underwent to D+C+P (83% and no complications were found in patients where no cervical plate was used. Regarding levels, both complications were identified in patients operated to one or two levels. However, in patients operated on three levels, only dysphonia was identified. CONCLUSION: The most frequent complication was dysphonia. Patients who presented more complications were those undergoing discectomy and fusion with cage and anterior cervical plate. All cases of dysphonia were in this group. The number of accessible levels does not seem to have affected the incidence of complications.

  14. Holistic approach to understanding anterior knee pain. Clinical implications.

    2014-10-01

    Anterior knee pain is one of the most frequent reasons for consultation within knee conditions. The aetiology is not well known, which explains the sometimes unpredictable results of its treatment. Normally, when we see a patient in the office with anterior knee pain, we only study and focus on the knee. If we do this, we are making a big mistake. We must not forget to evaluate the pelvis and proximal femur, as well as the psychological factors that modulate the course of the illness. Both the pelvifemoral dysfunction as well as the psychological factors (anxiety, depression, catastrophization and kinesiophobia) must be included in our therapeutic targets of the multidisciplinary treatment of anterior knee pain. We must not only focus on the knee, we must remember to "look up" to fully understand what is happening and be able to solve this difficult problem. The aetiology of anterior knee pain is multifactorial. Therefore, diagnosis and treatment of patellofemoral disorders must be individualized. Our findings stress the importance of tailoring physiotherapy, surgery and psycho-educational interventions to each patient.

    Wernicke's aphasia occurs after a stroke to classical language comprehension regions in the left temporoparietal cortex. Consequently, auditory-verbal comprehension is significantly impaired in Wernicke's aphasia but the capacity to comprehend visually presented materials (written words and pictures) is partially spared. This study used functional magnetic resonance imaging to investigate the neural basis of written word and picture semantic processing in Wernicke's aphasia, with the wider aim of examining how the semantic system is altered after damage to the classical comprehension regions. Twelve participants with chronic Wernicke's aphasia and 12 control participants performed semantic animate-inanimate judgements and a visual height judgement baseline task. Whole brain and region of interest analysis in Wernicke's aphasia and control participants found that semantic judgements were underpinned by activation in the ventral and anterior temporal lobes bilaterally. The Wernicke's aphasia group displayed an 'over-activation' in comparison with control participants, indicating that anterior temporal lobe regions become increasingly influential following reduction in posterior semantic resources. Semantic processing of written words in Wernicke's aphasia was additionally supported by recruitment of the right anterior superior temporal lobe, a region previously associated with recovery from auditory-verbal comprehension impairments. Overall, the results provide support for models in which the anterior temporal lobes are crucial for multimodal semantic processing and that these regions may be accessed without support from classic posterior comprehension regions.

    The human anterior cingulate cortex is distinguished by the presence of an unusual cell type, a large spindle neuron in layer Vb. This cell has been noted numerous times in the historical literature but has not been studied with modern neuroanatomic techniques. For instance, details regarding the neuronal class to which these cells belong and regarding their precise distribution along both ventrodorsal and anteroposterior axes of the cingulate gyrus are still lacking. In the present study, morphological features and the anatomic distribution of this cell type were studied using computer-assisted mapping and immunocytochemical techniques. Spindle neurons are restricted to the subfields of the anterior cingulate cortex (Brodmann's area 24), exhibiting a greater density in anterior portions of this area than in posterior portions, and tapering off in the transition zone between anterior and posterior cingulate cortex. Furthermore, a majority of the spindle cells at any level is located in subarea 24b on the gyral surface. Immunocytochemical analysis revealed that the neurofilament protein triple was present in a large percentage of these neurons and that they did not contain calcium-binding proteins. Injections of the carbocyanine dye DiI into the cingulum bundle revealed that these cells are projection neurons. Finally, spindle cells were consistently affected in Alzheimer's disease cases, with an overall loss of about 60%. Taken together, these observations indicate that the spindle cells of the human cingulate cortex represent a morphological subpopulation of pyramidal neurons whose restricted distribution may be associated with functionally distinct areas.

    Full Text Available Aim: To evaluate the diversity in techniques and approaches for anterior colporrhaphy among operators in Turkey. Methods: A survey evaluating the preoperative examination, technique of anterior colporrhaphy, operation choice and postoperative care was presented to surgeons. We contacted via directly, mail or telephone. We used 28 item questionnaire. Results: Majority (87.9% was composed of young gynecologists. Urologists composed of the 9.5% of the study population. The rate of paravaginal defect evaluation was 75.9% and mostly by inspection the presence of vaginal rugae. The use of transperineal 3D pelvic floor ultrasonography was low (5.7%. The evaluation of levator ani muscle defect was 46.6%. The usage of the transperineal 3D ultrasonography for levator ani muscle defect was 19 percent of operators. There were diversity in use of hydrodissection, fascial plication, excision of vaginal mucosa and suture choice. Usage of mesh for anterior colporrhaphy was limited (17.8% and mostly in recurrent cases (12.2%. Paravaginal defect repair rate was 31.9%. The urinary catheter was generally removed one or two day after operation. Vaginal pack usually removed 24 hours after. Conclusion: Several techniques and approaches for anterior vaginal wall repair among operators in Turkey. The variety of techniques suggested that there is no consensus on best surgical technique.

    Full Text Available Purpose: The aim of this study was to investigate possible predictive factors related to anterior chamber fibrin formation after vitreoretinal surgery in a large series of patients. Methods: The data of 185 eyes of 185 patients submitted to vitreoretinal surgery was reviewed. The following variables were evaluated: the postoperatively presence of fibrin, age, diabetes mellitus, the vitrectomy system gauge (20, 23 or 25 gauge, the type of vitreous substitute, the influence of prior surgical procedures and the combination with cataract extraction. To evaluate predictive factors for anterior chamber fibrin formation, univariate analysis was performed. A multivariate stepwise logistic regression model was adjusted to investigate factors associated with fibrin formation (p<0.05. Results: Fibrinoid anterior chamber reaction was found in 12 (6.4% patients. For multivariate logistic regression analysis, balanced salt solution (BSS, the chance of fibrin occurrence was 5 times greater (odds ratio 4.83, CI 95% 1.302 - 17.892; p=0.019, while combination with phacoemulsification increased the chance of fibrin formation by 20 times (odds ratio 20, CI 95% 2.480 - 161.347; p=0.005. No significant difference was found regarding other variables. Conclusion: Anterior chamber fibrin formation is an unwanted complication after vitreoretinal surgery. Factors such as combined performance of phacoemulsification and the use of balanced salt solution as a vitreous substitute may predispose the occurrence of this complication.

    2016-02-01

    The anterior fixation of the anterior process of the malleus has been studied in a number of Cetartiodactyla. This anterior process, also known as processus gracilis, is provided by the prearticular (gonial), a dermal bone, whereas the cartilage of Meckel becomes resorbed in perinatal ontogenetic stages. Posteriorly, the prearticular fuses with the cartilaginous caput of the malleus; rostrally, the prearticular (= processus gracilis) is always fixed to the anterior crus of the ectotympanic by an extremely thin splint (thickness fused to the adjacent bones already in juveniles. However, in ruminants, the tegmen tympani tends to disappear and the processus internus praearticularis appears as relatively small bony knob at the floor of the medial cranial cavity, and it seems not to be fused to the surrounding bones; in later age stages, it may become secondarily overgrown by the petrosal. This dorsally exposed processus internus praearticularis seems to be a synapomorphy of the Ruminantia. The functional meaning of this internal process of the prearticular, which is also developed to a minor degree in Carnivora, remains unclear at the moment - but we present some speculations about this.

    Full Text Available Resumen: La coartación de la aorta abdominal es una afección vascular no hereditaria poco frecuente, que afecta a hombres y mujeres por igual. Recientemente ha sido nombrada como “Síndrome aórtico medio”, y los hallazgos clínicos son similares a los de la CoAo típica. Para el diagnóstico, se debe recurrir a la resonancia magnética o a la arteriografía, y las opciones terapéuticas incluyen la dilatación percutánea con catéter-globo, el tratamiento quirúrgico y, por último, como opción más novedosa, la implantación de prótesis endovasculares. En este artículo presentamos el caso de una mujer de 45 años de edad, exfumadora, con antecedentes de artritis reumatoidea e hipertensión arterial que presentaba claudicación de miembros inferiores durante la marcha. Existía una disminución bilateral marcada de los pulsos femorales y el Doppler, y mostró un componente amortiguado en ambas arterias femorales y poplíteas. La AngioTAC encontró una estenosis significativa del tercio distal de la aorta abdominal infrarrenal, con hipoplasia marcada de la ilíaca derecha. La aortografía corroboró el diagnóstico (gradiente de 80 mmHg. A través de dos introductores arteriales por las arterias femorales se avanzaron dos catéteres-globo MATCH-35 de 5.0x80 mm que se inflaron simultáneamente y posteriormente, se implantó un stent MEDTRONIC “Bridge Assurant” de 10 x 30 mm en el segmento estenótico, sin complicaciones.

  16. MR imaging of anterior cruciate ligament injury: associated findings

    International Nuclear Information System (INIS)

    Authors investigated the associated findings and their value in the diagnosis of anterior cruciate ligament (ACL) injury in MR image. The knee MR images of 47 patients with ACL injury (complete;24, partial;23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operation were reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciate ligament (PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament and meniscus injuries were studied. The means(± 2 standard errors) of anterior translocation were different significantly in statistical analysis (ρ < 0.001, student t-test) between injury group (7.51 ± 1.16 mm) and normal group (-0.56 ± 0.92mm). In the level of 5mm of anterior translocation for the criteria of ACL injury, the sensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were also different statistically between injury group(0.23 ± 0.02) and normal group(0.17 ± 0.01)(ρ < 0.001). In the level of 0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% for each. Thirty one medial meniscus tear (66%), thirteen lateral meniscus tear (28%), ten medial collateral ligament injury (28%), one PCL injury(2%) were associated with ACL injury. The twenty nine bone marrow changes were found in twenty patients (43%) which included acutely injured seven patients. In acute cases, the bone marrow changes were depicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast to the changes in chronic cases depicted as focal low signal intensity lesions in variable location. Lateral femoral condylar notch depression were found in nine patients (19%) and avulsion fractures of anterior tibial spine in four patients(9%).

    Different clinical tests have been suggested in the literature as significant indicators of anterior shoulder instability. Sometimes patients with recurrent anterior shoulder instability may show some muscular guarding thus making the evaluation of specific clinical tests very difficult. These patients may also report a medical history with posterior shoulder pain that can be also elicited during some clinical manoeuvres. From September 2005 to September 2006 we prospectively studied patients who underwent an arthroscopic anterior capsuloplasty. Shoulder clinical examination was performed including anterior shoulder instability tests (drawer, apprehension and relocation tests). Furthermore the exam was focused on the presence of scapular dyskinesia and posterior shoulder pain. The patients were also evaluated with ASES, Rowe, SST (Simple Shoulder Test), Constant and UCLA (University of California at Los Angeles) scoring system preoperatively and at the latest follow-up time. In the period of this study we observed 16 patients treated for anterior gleno-humeral arthroscopic stabilisation, who preoperatively complained also of a posterior scapular pain. The pain was referred at the level of lower trapezium and upper rhomboids tendon insertion on the medial border of the scapula. It was also reproducible upon local palpation by the examiner. Four of these patients also referred pain in the region of the insertion of the infraspinatus and teres minor. After arthroscopic stabilisation the shoulder was immobilised in a sling with the arm in the neutral rotation for a period of 4 weeks. A single physician supervised shoulder rehabilitation. After a mean time of 6.8 months of follow-up, all the shoulder scores were significantly improved and, moreover, at the same time the patients referred the disappearance of the posterior pain. Posterior scapular shoulder pain seems to be another complaint and sign that can be found in patients affected by anterior shoulder instability

    Full Text Available Introduction: Bilateral shoulder dislocation are most commonly posterior type. These are most commonly due to seizure disorder and electrocution. Anterior shoulder dislocations occurring bilaterally without any predisposing factors are very rare. These types of injuries are due to trauma with a unique mechanism of injury. To best of our knowledge there are only few cases of similar kind are reported in literature. We hereby report a interesting case of posttraumatic, bilateral anterior dislocation of shoulder without associated fracture in a 45 old women without any predisposing pathoanatomy.Case Report: A 45-year-old women presented to casualty with sudden onset of pain and restriction of movement in both shoulders fallowing trauma. Immediately post trauma she had severe pain and restriction of both shoulders. On examination arms were abducted and externally rotated. Bilateral shoulder movements were painful and restricted . There was loss of round contour of shoulder with increased vertical diameter of axilla anteriorly. Radiological examination revealed bilateral anterior dislocation of the shoulders without any associated fractures. Closed reduction done by Milch technique after intraraticular lignocaine injection. MRI of bilateral shoulder showed no pathological lesion. Both shoulders were immobilized with a shoulder immobilizer for three weeks.Conclusion: Most of the bilateral shoulder dislocations are posterior type seen in seizure disorders. Bilateral traumatic anterior shoulder dislocations are rare and are seen as a result of unique mechanism of injury. In our case patient had a fall on her elbows causing forced extension. If diagnosed and treated promptly completely normal function of the shoulders can be restored.

    Full Text Available BACKGROUND Anterior Cruciate Ligament (ACL tear is the most common serious ligamentous injury to the knee joint. Anterior Cruciate Ligament (ACL injury is quite common among young active population, athletes and contact sports. The exact incidence of anterior cruciate ligament tears is not known as the cases are being under reported. The ACL is the primary stabilizer against anterior translation of the tibia on the femur and is important in counteracting rotation and valgus stress. MATERIALS AND METHODS Between November 2012 to October 2014, 34 consecutive patients who underwent arthroscopic assisted ACL reconstructions in the Department of Orthopedics and Traumatology, King George Hospital, Visakhapatnam were the material in our study. Age groups between 18 to 45 years considered. We utilised both BPTB and Quadrupled hamstring graft depending on the patient’s age, outcome testing in all cases was performed at the latest follow-up (at least 6 months. Post-operative physiotherapy rehabilitation protocol followed for 06 months. RESULTS Standard protocol of Lysholm and IKDC knee scoring system were used for evaluation of the results of the surgery during followup. Patients were evaluated periodically at preop, 3 months, 6 months, 12 months, 18 months and 24 months. CONCLUSION Patients with isolated ACL injury had better outcome compared to patients who underwent associated meniscectomy. Most common mechanism of injury was activity of sports in 20 patients. Postoperatively at 3 months, anterior drawer’s was 1+ in 6, 29 (85.2% patients had normal range of motion; 29 (85.29% patients had 5/5 quadriceps power (MRC grading 94% of them had 5/5 power at latest followup. No significant difference between outcomes of BPTB and Hamstrings graft. Functional outcome of our study were similar to the previously published studies.

    Objective:To demonstrate and evaluate a modified simple method about self-reduction of anterior shoulder dislocation for significance in the emergency room. Methods:TheBoss-Holzach-Matter method for self-reduction of anterior shoulder disloaction is described.Patients with an anterior shoulder dislocation were retrospectively analysed concerning age, gender, type of anterior shoulder dislocation, occurrence of associated fractures, time between injury and reduction, reduction time, and method of reduction with its respective success rate. Results:Eighty-six patients(52 men,34 women, mean age49 years) were treated fromJanuary 2010 toJune2014.The reduction time ranged between20 seconds and6 min(mean1.5 min). Subcoracoid type of shoulder dislocation was seen in72 cases(84%), subglenoid type in14 cases(16%).Associated factures were seen in20 cases, proportionally more often in subgleboid dislocations,12 at the greater tuberosity,6 at the inferior rim of the glenoid fossa and2 at both localizations.TheBoss-Holzach-Matter method was used in35 cases with a success rate of 71.5%; dieKocher method and traction/countertraction method with premedication were used in 14 cases and17 cases with success rates of64% and70%, respectively.All other cases and the failed primary attempts required hyponotic medication.All patients older than70(n=16) were not able to perform the self reducing procedure. Conclusion:The presentedBoss-Holzach-Matter method for reduction of anterior shoulder dislocation is a simple method without the need of anaesthesia, but cooperation from patients is crucial.The successful rate is comparable with other established methods.

    Full Text Available En el 2000, el Gobierno Nacional de Colombia se comprometió con la Organización de Naciones Unidas (ONU, con el Banco Mundial (BM, con el Fondo Monetario Internacional (FMI y con la organización para la Cooperación y el Desarrollo Económicos (OCDE a cumplir hacia el 2015 con un marco de ocho objetivos, dieciocho metas y cuarenta y ocho indicadores, con el fin de medir los progresos hacia el logro de los Objetivos de Desarrollo del Milenio (ODM. El presente trabajo se concentró en examinar los objetivos referidos a la pobreza. Al analizar el Plan Nacional de Desarrollo (PND 2002-2006 “Hacia un Estado comunitario”, no se observó un enlace directo con la consecución de los logros de los ODM sobre pobreza, ya que ésta no aparece como un objetivo explícito en tal plan. Posteriormente, al analizar el PND 2006-2010 “Estado Concordancia entre el cumplimiento de los Objetivos de Desarrollo del Milenio sobre pobreza, con los Planes Nacionales de Desarrollo de Colombia 2002-2010: evaluación con un modelo de cointegración comunitario: desarrollo para todos”, se encontró que hay una mejora sustancial en el tema de pobreza con respecto al PND anterior. Quizás esto se debe a que –como se anotó antes– en el PND 2002-2006 no se presentó el tema de la pobreza explícitamente, y a que ésta seguía siendo muy alta en el 2003. En dicho plan se presenta el tema de la pobreza como un objetivo general con proyecciones de metas anuales y con un plan de inversiones explícito sobre la reducción de la pobreza. A partir del modelo de cointegración estimado, se infiere que los gastos del gobierno colombiano dedicados al tema de la pobreza en el periodo que abarca los dos últimos PND no han sido suficientes para obtener las metas de ODM que el país se fijó cumplir en el 2015.

A implementação desse sistema de tratamento reduz o número de pacientes indicados para a cirurgia ortognática e simplifica muitos problemas. Nessa abordagem, os dentes posteriores são intruídos e a mandíbula sofre um giro no sentido anti-horário, diminuindo a altura facial inferior e projetando os pogônios de tecidos duro e mole. OBJETIVO: o presente artigo apresenta os fundamentos da mecânica ortodôntica para correção da mordida aberta anterior e os ilustra com uma série de casos clínicos.INTRODUCTION: The treatment of facial deformities and malocclusions, such as anterior open bite, was one of the first applications of miniplates for orthodontic anchorage. The use of this treatment system reduces the number of patients referred to orthognathic surgery and simplifies many problems. This approach applies intrusive forces to posterior teeth, and the mandible undergoes counterclockwise rotation, which decreases lower facial height and advances the projection of hard and soft tissue pogonions. OBJECTIVE: This study describes the principles of orthodontic mechanics in the correction of anterior open bite and illustrates these principles with a series of cases.

    Full Text Available Introduction The most frequent procedure in treatment of acute or chronic anterior cruciate ligament (ACL rupture is the so called bone-tendon-bone reconstruction. A transverse dislocated patella fracture is a rare complication of this procedure with an incidence of 0.23%-2.3%. In a five year period, (1998-2002, 407 arthroscopic reconstructions of the anterior cruciate ligaments were done at our Clinic, and there was only one case of patella fracture. Case report An 18-year-old female patient, a handball player, suffered an acute rupture of anterior cruciate ligament of the left knee, so arthroscopic bone-tendon-bone reconstruction of the anterior cruciate ligament was performed. After adequate skin incision, a bone graft was taken from the patella and upper part of trapezoid tibia, which was 25 mm long, 10 mm wide and 5 mm thick, together with a part of patellar ligament. After the remains of the anterior cruciate ligament had been arthroscopically removed, tunnels were made in tibia and femur and a graft was inserted and fixed with two metal interference screws. Knee stability was tested, and drainage was put in the knee joint. The wound was closed by layers. The quadriceps exercises and passive knee movements started immediately. Full range of movements was accomplished six weeks later when the patient started to walk with full weight-bearing on her operated leg. Three weeks later, (nine weeks after the operation, the patient has accidentally lost her balance and fell. A transverse, dislocated fracture of the left patella was diagnosed and osteosynthesis of the fractured patella with two Kirschner wires and a metallic loop was performed. Postoperatively, full range of movement was allowed.

  8. RadCon: A Radiological Consequences Model

    International Nuclear Information System (INIS)

    RadCon estimates the dose received by user selected groups in the population from an accidental release of radionuclides to the environment. The exposure pathways considered are external exposure from the cloud and ground and internal exposure from inhalation and ingestion of contaminated food. Atmospheric dispersion modelling is carried out externally to RadCon.Given a two dimensional time varying air and ground concentration of radioactive elements, RadCon allows the user to: view the air and ground concentration over the affected area, select optional parameters and calculate the dose to people,display the results to the user, and change the parameter values. RadCon offers two user interfaces: 1) the standard graphical user interface which is started using Java DoseApp at the command line, or by setting up a shortcut to this command (particularly when RadCon is installed on a PC) and 2) the text based interface used to generate information for the model inter-comparison exercise . This is initiated using Java BIOMASS at the command line, or an equivalent shortcut. The text based interface was developed for research purposes and is not generally available. Appendices A, B and C provide a summary of instructions on setting up RadCon. This will generally be carried out by the computer support personnel

    Bordetella pertussis synthesis a variety of virulence factors including a calmodulin-dependent adenylate cyclase (AC) toxin. Treatment of anterior pituitary cells with this AC toxin resulted in an increase in cellular cAMP levels that was associated with accelerated exocytosis of growth hormone (GH), prolactin, adrenocorticotropic hormone (ACTH), and luteinizing hormone (LH). The kinetics of release of these hormones, however, were markedly different; GH and prolactin were rapidly released, while LH and ACTH secretion was more gradually elevated. Neither dopamine agonists nor somatostatin changes the ability of AC toxin to generate cAMP (up to 2 h). Low concentrations of AC toxin amplified the secretory response to hypophysiotrophic hormones. The authors conclude that bacterial AC toxin can rapidly elevate cAMP levels in anterior pituitary cells and that it is the response that explains the subsequent acceleration of hormone release.

    2010-12-01

    A 50-year-old Chinese man presented with rapidly progressive unilateral ophthalmoplegia and then an ipsilateral afferent pupil defect. CT and MRI revealed a mass centered in the anterior clinoid process causing bone destruction and showing high T1 and T2 signal intensity indicative of mucosal protein secretion. These imaging features suggested a mucocele, which may have resulted from sequestration of a clinoidal extension of the sphenoid sinus. The sphenoid sinus was opened via an image-guided endoscopic approach, and the lesion incised. There were no complications. The ophthalmoplegia and afferent pupil defect had completely resolved within 1 week of surgery. This is the eighth reported case of anterior clinoidal mucocele, a rare cause of ophthalmoplegia or optic neuropathy. Advances in endoscopic instrumentation, navigation systems, and intraoperative imaging have reduced the operative risk and made the endoscopic approach a feasible and safer alternative to open surgery for this condition.

    Full Text Available Although anterior cervical arthrodesis is an effective procedure for the treatment of cervical disorders, the method has some complications. Here, we describe this rare complication of cervical instrumentation with a literature review. A 23-year-old male patient was operated for a C6-C7 dislocation. At postoperative month 10, he presented with hemoptysis and dysphagia. Cervical roentgenograms showed anterior migrations of one broken screw and a plate-locking screw at the C6 corpus. One screw was missing. We concluded that the missing screw had perforated the esophagus and had been eliminated spontaneously through the gastrointestinal tract. No screw should migrate. Even loose screws should be noted in follow-up X-ray studies. If such findings are detected, a second operation for revision should be considered as soon as possible to prevent potentially fatal complications.

    Full Text Available The important role of the tooth size information is in making diagnosis and treatment plan of the cases with malocclusion. A lot of studies have been done in this aspect such as about tooth size with its variation, and also the ratio of maxillary to mandibular tooth size. The most famous tooth size analysis is Bolton analysis with his anterior ratio and overall ratio. Because the accordance of those ratio is not found in all orthodontic cases, some studies (Korbitz, Neff, Moyers and Steadman tried to relate the anterior ratio with the amount of overjet and overbite in orthodontic treatment. Those relationship was found strong, but there are also other analysis that should be considered in treating orthodontic cases.

    Severe vertical ridge deficiency in the anterior maxilla represents one of the most challenging scenarios in bone regeneration. Under ideal circumstances, guided bone regeneration in combination with soft tissue management has shown predictable esthetic and functional outcomes. Success largely relies on primary wound closure during and after the surgical procedure. Surgical sites present different challenges that need to be considered when designing the flap. The goal of this article is to propose a classification of flap designs that considers vestibular depth and scar formation around the periosteum when performing vertical ridge augmentation in the atrophic anterior maxilla. The four clinical conditions proposed under this classification are (1) shallow vestibule with healthy periosteum, (2) deep vestibule with healthy periosteum, (3) shallow vestibule with scarred periosteum, and (4) deep vestibule with scarred periosteum. The classification will allow clinicians to achieve tension-free closure and more predictable vertical bone gain.

    Full Text Available OBJECTIVE: The autors report a case of a traumatic rupture of the tibialis anterior tendon (TTA that was early diagnosed and treated in the emergency service. This is a rare clinical entity with few cases reported in the literature. CASE REPORT: A 66-year old female presented at the emergency service complaining about pain at the anterior aspect of her ankle and inability to walk normally, after a fall. Physical examination revealed clinical signs for TTA rupture, which was later confirmed by ultrasound. Surgical treatment was performed immediately â€" the tendon was anchored into the medial cuneiform with a soft tissue-to-bone anchor. The follow-up revealed good functional result. CONCLUSION: Physical examination and a high index of suspicion are important when facing a patient who had sustained an ankle trauma. The TTA rupture is a diagnosis to consider because unrecognized ruptures led to important functional deficits and poor functional results.

    The serratus anterior plane block has been described for analgesia of the hemithorax. This study was conducted to determine the spread of injectate and investigate the anatomical basis of the block. Ultrasound-guided serratus anterior plane block was performed on six soft-fix embalmed cadavers. All cadavers received bilateral injections, on one side performed with 20 ml latex and on the other with 20 ml methylene blue. Subsequent dissection explored the extent of spread and nerve involvement. Photographs were taken throughout dissection. The intercostal nerves were involved on three occasions with dye, but not with latex. The lateral cutaneous branches of the intercostal nerve contained dye and latex on all occasions. The serratus plane block appears to be mediated through blockade of the lateral cutaneous branches of the intercostal nerves. Anatomically, serratus plane block does not appear to be equivalent to paravertebral block for rib fracture analgesia. PMID:27440171

    Full Text Available Genetic diseases are congenital or acquired hereditary diseases that result from structural/functional disorders of the human genome. Today, the genetic factors that play a role in many diseases are being highlighted with the rapid progress in the field of genetics science. It becomes increasingly important that physicians from all disciplines have knowledge about the basic principles of genetics, patterns of inheritance, etc., so that they can follow the new developments. In genetic eye diseases, ophthalmologists should know the basic clinical and recently rapidly developing genetic characteristics of these diseases in order to properly approach the diagnosis and treatment and to provide genetic counseling. In this paper, anterior segment eye diseases of genetic origin are reviewed, and aniridia, anterior segment dysgenesis, glaucoma, corneal dystrophies, cataract, ectopia lentis, myopia, and other refractive errors are covered.

    The aim of this article is to discuss the different types of monolithic ceramic crowns that can be placed on anterior teeth with existing shoulder preparations. Anterior crowns were indicated for the teeth 12 to 22 in the present case. The patient, a 65-year-old male, had received all-ceramic crowns 20 years earlier, which had started to develop cracks and palatal fractures over the last few years. The patient's teeth were prepared and four sets of crowns were fabricated using different monolithic ceramic materials: IPS e.max CAD, Cerec Blocs C In, VITABLOCS Real Life, and ENAMIC. Both shade characterization and crystallization firing were performed on the monolithic lithium disilicate glass ceramic crowns. The silicate ceramic crowns received glaze firing alone. The crowns made of hybrid ceramic (ENAMIC) were treated with a polymer sealant. PMID:24555406

    Grimm, F; Ebner, F H; Honegger, J

    2013-05-01

    Meningiomas are the most common form of primary intracranial tumors. If the anterior visual pathways are affected clinical visual compromise, visual field defects, oculomotor nerve disturbances or propotosis are predominant. Meningiomas of the anterior visual pathway remain therapeutically challenging due to the direct anatomical relationship to the circulus arteriosus cerebri, the cavernous sinus and cranial nerves. The therapy of choice is microsurgical resection. In many cases a curative approach can be achieved with modern surgical techniques and simultaneously maintaining patient quality of life. Problematic are cases in which resection would be associated with the risk of clinical impairment and in these cases radiotherapy is an important therapeutic option. In cases involving complex invasiveness an interdisciplinary treatment to control local clinical symptoms is favored. PMID:23604251

    Full Text Available One third of patients with antiepileptic-resistant temporal lobe epilepsy (TLE will have to undergo surgery for a better seizure control. Anterior temporal lobectomy (ATL is done for mesial temporal sclerosis that is the most common histopathological lesion associated with TLE. Psychiatric manifestations following ATL are not uncommon with depressive symptoms more common with left ATL and manic symptoms following right ATL. Mr. A is a 42-year-old left cerebral dominant (Confirmed by WADA test male with no past history of psychiatric illness who had undergone anterior temporal lobectomy with amygdalohippocampectomy. He started having manic episodes post operatively which subsided with antipsychotics. He had multiple such episodes over the next 13 years with minimal inter episodic symptoms. This is a rare instance of manic symptoms following left-sided ATL that emphasizes the need for better understanding of the cerebral laterality of affective symptoms.

    Full Text Available No- or minimal-preparation veneers associated with enamel preservation offer predictable results in esthetic dentistry; indirect additive anterior composite restorations represent a quick, minimally invasive, inexpensive, and repairable option for a smile enhancement treatment plan. Current laboratory techniques associated with a strict clinical protocol satisfy patients’ restorative and esthetic needs. The case report presented describes minimal invasive treatment of four upper incisors with laminate nanohybrid resin composite veneers. A step-by-step protocol is proposed for diagnostic evaluation, mock-up fabrication and trial, teeth preparation and impression, and adhesive cementation. The resolution of initial esthetic issues, patient satisfaction, and nice integration of indirect restorations confirmed the success of this anterior dentition rehabilitation.

  4. Effect of bone loss in anterior shoulder instability

    Garcia, Grant H; Liu, Joseph N; Dines, David M; Dines, Joshua S

    2015-01-01

    Anterior shoulder instability with bone loss can be a difficult problem to treat. It usually involves a component of either glenoid deficiency or a Hill-Sachs lesion. Recent data shows that soft tissue procedures alone are typically not adequate to provide stability to the shoulder. As such, numerous surgical procedures have been described to directly address these bony deficits. For glenoid defects, coracoid transfer and iliac crest bone block procedures are popular and effective. For humeral head defects, both remplissage and osteochondral allografts have decreased the rates of recurrent instability. Our review provides an overview of current literature addressing these treatment options and others for addressing bone loss complicating anterior glenohumeral instability. PMID:26085984

  5. MR for assessing anterior cruciate ligament reconstructions by tendon grafts

    International Nuclear Information System (INIS)

    150 patients were examined via magnetic resonance (MR) after anterior cruciate (ACL) ligament reconstruction (76 patellar tendon grafts, 53 semitendinosous tendon grafts and 21 sutures). The results of MR were compared with clinical tests (Lachman, pivot-shift and anterior drawer test), in 2 cases with the operative findings, and in one case with arthroscopy findings. In 91% of patients with a clinically stable knee we found a continuous low-intensity ligamental structure. 10 patients were examined twice or more between 8 days and 6 months after surgery. Ligamental structures of low signal intensity did not significantly change their MR characteristics. MR is a valuable noninvasive method for evaluating ligament reconstructions. (orig./GDG)

    1992-01-01

    Three patients developed signs of a unilateral cervical cord lesion 6 to 36 h after the acute onset of severe cervico-brachial pain. The neurological deficit progressed over 6 to 18 h. On the painful side a central Horner's syndrome, a hemiparesis with plegia of the hand, and a slight pallhypaesthesia were found. On the opposite side thermhypaesthesia and hypalgesia were noted with a level at the dermatome C5 or C6. T2-weighted MR images revealed in one patient a small area of increased signal intensity restricted to one half of the cervical cord, and electromyography in another patient showed after 6 months evidence of segmental chronic denervation. Both abnormalities were found at the clinically expected level. The findings are consistent with a small infarction of the cervical cord in the perfusion territory of a central (sulco-commissural) artery, a duplicated anterior spinal artery or an anterior spinal branch of the vertebral artery.

Objectives: The current study aimed to compare RV function in patients with inferior and anterior MI. Patients and Methods: During the study period, 60 patients consecutively presented to the Emergency Department with chest pain were divided into two groups based on their electrocardiographic findings. Accordingly, 25 patients had inferior MI (IMI group and 35 ones had anterior MI (AMI group. Echocardiography was performed 48 hours after starting the standard therapy. Conventional echocardiographic parameters and Tissue Doppler Imaging (TDI measurements were acquired from the standard views. Student t-test and the chi-square test were respectively used for comparisons of the normally distributed continuous and categorical variables in the two groups. Besides, P < 0.05 was considered to be statistically significant.

    Full Text Available A luxação glenoumeral anterior bilateral é uma ocorrência rara. Apresentamos um caso de luxação glenoumeral anterior bilateral com origem após uma queda da própria altura. O interesse desta publicação reside no fato de se tratar de uma raridade clínica com poucos casos descritos na literatura. Paciente do sexo feminino com 89 anos recorre ao serviço de urgência (SU após queda referindo dor intensa e incapacidade de mobilização de ambos os ombros. Ao exame objetivo apresentava sinais clínicos suspeitos de luxação glenoumeral anterior bilateral confirmados por radiografia. Ambas as luxações foram reduzidas no SU pela técnica de Milch modificada, com sucesso. Quando existe uma força simétrica e síncrona sobre os ombros e estes se apresentarem dolorosos e com limite funcional significativo, a suspeita de luxação glenoumeral bilateral, embora rara, é um diagnóstico diferencial a ter em conta.Bilateral anterior glenohumeral dislocation is a rare occurrence. We present a case of bilateral anterior glenohumeral dislocation caused by a fall. The interest in publishing this case is that this is a clinical rarity with few cases reported in the literature. An 89-year-old female patient was brought to the emergency department after a fall, complaining of intense pain in both shoulders and inability to move them. Objective examination showed clinical signs giving the suspicion of bilateral anterior glenohumeral dislocation, which was confirmed by x-ray imaging. Both dislocations were successfully reduced in the emergency department using the modified Milch technique. When a synchronous and symmetrical force has acted on both shoulders and these are painful with significant functional limitation, the suspicion of bilateral glenohumeral dislocation is a differential diagnosis to be considered, even though it is rare.

  20. Anterior knee pain: an update of physical therapy.

    Science.gov (United States)

    Werner, Suzanne

    2014-10-01

    Anterior knee pain is one of the most common knee problems in physically active individuals. The reason for anterior knee pain has been suggested to be multifactorial with patella abnormalities or extensor mechanism disorder leading to patellar malalignment during flexion and extension of the knee joint. Some patients complain mostly of non-specific knee pain, while others report patellar instability problems. The patients present with a variety of symptoms and clinical findings, meaning that a thorough clinical examination is the key for optimal treatment. Weakness of the quadriceps muscle, especially during eccentric contractions, is usually present in the majority of anterior knee pain patients. However, irrespective of whether pain or instability is the major problem, hypotrophy and reduced activity of the vastus medialis are often found, which result in an imbalance between vastus medialis and vastus lateralis. This imbalance needs to be corrected before quadriceps exercises are started. The non-operative rehabilitation protocol should be divided into different phases based on the patient's progress. The goal of the first phase is to reduce pain and swelling, improve the balance between vastus medialis and vastus lateralis, restore normal gait, and decrease loading of the patello-femoral joint. The second phase should include improvement of postural control and coordination of the lower extremity, increase of quadriceps strength and when needed hip muscle strength, and restore good knee function. The patient should be encouraged to return to or to start with a suitable regular physical exercise. Therefore, the third phase should include functional exercises. Towards the end of the treatment, single-leg functional tests and functional knee scores should be used for evaluating clinical outcome. A non-operative treatment of patients with anterior knee pain should be tried for at least 3 months before considering other treatment options.
