    Full Text Available En este estudio se evaluó el método SODIS y SODIS combinado con Artemisia annua como una alternativa para la desinfección del agua en comunidades sin acceso a agua segura. Se determinó la eficiencia del método en la remoción de Escherichia coli, Bacillus subtilis, Enterococcus faecalis y Salmonella typhimurium usando botellas tipo PET con agua destilada estéril y una concentración inicial de 1x106 UFC/ml de cada microorganismo. Para la combinación SODIS-A. annua se adicionó a las botellas una infusión de A. annua al 10% (v/v; las botellas fueron expuestas al sol durante mínimo 6 horas y se determinaron las variables temperatura del agua, radiación solar y turbidez. Se encontró que el tratamiento SODIS fue más eficiente en la remoción de los cuatro microorganismos que el tratamiento SODIS + A. annua. Las remociones más altas se encontraron a partir de las cuatro horas de exposición para las especies bacterianas en estado vegetativo.

    con alto valor agregado, como la gasolina, turbosina o diesel, entre otros. Con la nueva reconfiguracion de las refineria mexicanas de Cd. Madero y Cadereyta y proximamente la terminacion de la reconfiguracion de la refineria de Minatitlan, Veracruz, grandes cantidades de coque se estaran produciendo, con la posibilidad de usarlo mediante la tecnologia de gasificacion para producir un gas sintetico limpio (gasl) con caracteristicas energeticas apropiadas para utilizarse como combustible en un ciclo combinado existente en Mexico. En Mexico se han estimado las posibilidades de generacion de energia electrica a partir del uso del coque de petroleo utilizado la tecnologia de gasificacion o usando generadores de vapor de lecho fluidizado, como es el caso de las planta de potencia TEG en Taquin, San Luis Potosi. Tal es el hecho, que actualmente PEMEX refinacion, tiene terminado el proyecto para construir en Tuxpan, Veracruz una refineria procesadora de crudo Maya con un alto contenido de azufre y junto a la termoelectrica de Tuxpan, contemplandose la posibilidad de aplicar el concepto de ciclo combinado con gasificacion integrada (CCGI); con esta infraestructura sera posible consumir el coque generado por las refinerias mexicanas. La generacion electrica esperada es de 500 MW, de los cuales 100 MW seran para consumo propio de la refineria y 400 MW libres para cubrir la demanda de energia electrica de la zona noreste y centro del pais. El coque de petroleo derivado de las refinerias del pais puede ser utilizado para la generacion limpia de electricidad mediante su gasificacion e integracion a una planta de ciclo combinado existente. La ubicacion estrategia del ciclo combinado Tula, el cual se encuentra adyacente a la refineria Miguel Hidalgo presenta la oportunidad de aplicar la tecnologia de gasificacion como una alternativa viable: primeramente, para la utilizacion de coque de petroleo que actualmente se esta produciendo en las refinerias de Mexico o la utilizacion del

    A description is presented of the operation of the Combined Cycle Power Stations with Integrated Gasification (CCGI) where the use of solid fuels (coal, vacuum residues, petroleum coke, and biomass) or liquids is possible in a thermal power station with the efficiency and many of the own environmental benefits of the combined cycles. The gasification process is analyzed, that is a thermo-chemical process by means of which a fuel that is in solid state or liquid becomes to the gaseous state by means of a partial oxidation and the obtained gas of this process is called synthesis gas (syngas, by its abbreviations in English) that is used in Combined Cycle Power Stations as a substitute for the natural gas. Also the other components of this type of power stations are shown, such as the air separating unit, and some of the modifications that are due to make to adapt a gas turbine so that it uses syngas, and the considerations of their integration with the air separating unit to optimize the operation of the plant are detailed. A comparison of efficiency values of power stations CCGI with the conventional carbon-electric and the power stations of combined cycle that use natural gas is also shown. Finally the emissions of pollutants of SO{sub 2}, NO{sub x} and CO{sub 2} are analyzed. The possibility of using fuels like petroleum coke and vacuum tower residues that are produced in the Cadereyta refinery is studied for the possible construction of a CCGI power station in Mexico.

Biopower is a product of the Nuclear Institute for Biotechnology and Genetic Engineering (NIBGE, Pakistan, which contains species of associative and endophytic diazotrophs. EM (effective microorganisms, a product developed by Japanese scientists, consists of co-existing beneficial microorganisms, mainly species of photosynthetic and lactic acid bacteria, as well as yeast. Applying Biopower adversely affected plant growth and yield in NPK fertilizer amendment. Conversely, this biofertilizer markedly enhanced plant growth and yield in green manure amended soil while its effect was not significant in farmyard manure amendment. In green manure amendment, applying EM enhanced grain yield by 46%. Co-inoculation of Biopower and EM evidently improved root and shoot growth in farmyard manure amended soil. This study concludes that the two biofertilizers clearly enhanced shoot biomass and grain yield in green manure amended soils.El presente estudio en macetas fue realizado para investigar el efecto de la aplicación combinada de dos biofertilizantes comerciales, Biopower y EM (Effective Microorganisms, en el crecimiento y producción de arroz (Oryza sativa L. en suelos enmendados con estiércol de granja, abono verde y fertilizantes NPK.

    A brief description of a combined cycle power station that uses synthesis gas, better known as CCGI, is presented. The costs of the initial investment of several plants of this type, that have been described in literature, are analyzed and the predictions that different experts do on the costs that are expected in the near future are reviewed. Also the maintenance expenses that would be expected during the normal operation and the main maintenance are examined. The availability factors that reasonably must be considered based on the recent experiences are analyzed. Afterwards the sense which that the plant factor has in one of natural gas and one of synthesis, where generally are used as base plant. The costs of the different fuels that can be used in a CCGI are examined. Finally the leveled cost of the energy for both cases is calculated and the sensitivity of both to the cost of the respective fuels is examined. The result is presented in graphical form to show in a first attempt, the circumstances under which one or another technology could be preferable. It is made clear that the data used in this brief study are the best reasoned estimation and in no way they must be considered as definitive, in special in those of investment and maintenance of the CCGI where the operation history is still short.

    Full Text Available Para comparar la eficacia para dejar de fumar de la terapia cognitiva conductual intensiva (TCC/I, la TCC/I con parches de nicotina (TCC/I+PN y la terapia cognitiva conductual no intensiva con parches de nicotina (TCC/NI+PN se realizó un estudio experimental de medidas repetidas con 235 fumadores adultos asignados aleatoriamente a uno de esos tres tratamientos. Entre los pacientes que completaron el tratamiento (n= 152 la TCC/I+PN mostró tasas de abstinencia a los 6 meses y al año, mayores que la TCC/NI+PN, mientras que la TCC/I mostró tasas de abstinencia que no eran significativamente diferentes de las de los otros dos tratamientos. Estos resultados sugieren que los parches de nicotina se deberían utilizar siempre con una terapia cognitiva conductual lo más intensiva posible y que la utilización de esta última terapia en solitario debería gozar de mayor relevancia en las guías clínicas para dejar de fumar.

    Full Text Available Resumen En la tetralogía de Fallot con ramas pulmonares hipoplásicas, una alternativa para evitar cirugías paliativas es la valvuloplastia percutánea pulmonar con catéter de globo. Cuando existen colaterales arteriovenosas mayores que producen sobrecarga de volumen de las cavidades izquierdas, ocluirlas previamente mejora los resultados quirúrgicos. Se presentan dos pacientes con colaterales aorto-pulmonares, cerradas en el laboratorio de hemodinámica 24 horas antes de la cirugía, y dos niños a quienes se les dilató la válvula pulmonar y luego recibieron cirugía, siete y nueve meses después, respectivamente. El seguimiento medio ha sido de cinco años sin complicaciones. Las técnicas de cateterismo intervencionista previas a la cirugía de la tetralogía de Fallot, son factibles y pueden contribuir a disminuir el número de paliaciones y a mejorar los resultados de la corrección quirúrgica de la enfermedad en casos seleccionados. / Abstract In tetralogy of Fallot with hypoplastic pulmonary arteries, an alternative to avoid palliative surgeries is percutaneous pulmonary valvuloplasty using a balloon catheter. When there are major arteriovenous collaterals producing volume overload of the left chambers, their previous occlusion improves surgical outcomes. Two patients with aorto-pulmonary collaterals, closed in the laboratory of hemodynamics 24 hours before surgery, and two children who underwent pulmonary valve dilation and then surgery, seven and nine months afterwards, respectively, are reported. Mean follow-up was five years without complications. Interventional catheterization techniques before surgery for tetralogy of Fallot are feasible and can help reduce the number of palliations and improve the results of surgical correction of the disease in selected cases.

    Full Text Available At the beginning of the decade of the nineties, the industrial interest for TRIP steels leads to a significant increase of the investigation and application in this field. In this work, the flexibility of neural networks for the modelling of complex properties is used to tackle the problem of determining the retained austenite content in TRIP-steel. Applying a combination of two learning algorithms (backpropagation and creeping-random-search for the neural network, a model has been created that enables the prediction of retained austenite in low-Si / low-Al multiphase steels as a function of processing parameters.

    A partir de los años noventa, el interés que los aceros TRIP despiertan en la industria ha producido un incremento considerable de su estudio y aplicación. En este trabajo, aprovechando la flexibilidad que las redes neuronales proporcionan para la modelización de propiedades complejas, se ha abordado el problema de la determinación de la austenita retenida en los aceros TRIP. Una combinación de dos algoritmos de aprendizaje (retropropagación y búsqueda aleatoria progresiva de la red neuronal ha permitido crear un modelo que predice la cantidad de austenita retenida en aceros multifase con bajo contenido en aluminio y silicio en función de los parámetros de procesado.

    Full Text Available Background: little information is available on the effect of pegylated interferon (PEG and ribavirin (RBV in patients with chronic hepatitis due to virus C (CHC who were non-responders to previous treatment. Objectives: to evaluate response to treatment in patients who were non-responders to previous treatment. Methods: one hundred and twenty-four patients who were non-responders to previous treatment were included. All patients were treated with PEG alpha 2b interferon (dose: 1.5 mg/kg body weight and RBV (weight-dependent dosage. A qualitative PCR of virus C after six months was evaluated. In those in whom this was positive, treatment was discontinued; in those who were negative treatment was continued to the end of the year. Results: response following treatment (RFT was 35.4% (44 patients, and sustained viral response (SVR 29.8% (37 patients. No relation was observed between RFT, SVR and any previous treatment. RFT was dependent on low initial viremia and SVR was significantly and independently related to low serum hepatitis C RNA and a non-1 genotype. In general, treatment was well tolerated. Medication was discontinued in 5 patients, and doses reduced in 18. Conclusion: on retreatment with PEG and RBV a SVR of 29.8% was achieved in patients who had not responded to previous treatment, so its use in this group of patients is indicated.Introducción: existe poca información del resultado del tratamiento con interferón pegilado (PEG y ribavirina (RBV en enfermos con hepatitis crónica por virus C (HCC no respondedores a tratamientos previos.

    Introducción: la Aspergilosis Invasiva (AI) del Sistema Nervioso Central (SNC) es infrecuente y ocurre generalmente en pacientes inmunocomprometidos. Puede presentarse con cuadros de meningitis, aneurismas micóticos, infartos o abscesos. Es una infección con pronóstico reservado y puede afectar el SNC de forma primaria o secundaria a partir de un foco que se disemina por vía hematógena. Presentamos el caso de un paciente con AI con invasión primaria a nivel óseo y diseminación posterior al cerebro. Caso clínico: Paciente masculino de 25 años con diagnóstico de leucemia linfática aguda en tratamiento quimioterápico que presentó neumonitis por metotrexate por lo que inicia tratamiento con corticoides. Posteriormente agregó cervicalgia y con el diagnóstico de osteomielitis cervical se realiza punción bajo tomografía computada (TC) sin aislarse gérmenes. Se colocó Halo Vest e inició tratamiento antibiótico empírico. Posteriormente presentó afasia de expresión secundaria a lesión frontal izquierda. Se realizó evacuación de absceso cerebral aislando A. fumigatus. El tratamiento antibiótico específico posterior permitió una buena respuesta clínica y radiológica. Conclusión: La presencia de lesiones en el SNC de pacientes inmunocomprometidos debe incluir a las micosis como diagnóstico diferencial. La evacuación quirúrgica permite llegar rápidamente al diagnóstico mejorando la respuesta posterior al tratamiento antibiótico. Para evaluar la respuesta terapéutica y posibles recaídas se debe realizar un seguimiento periódico clínico radiológico.

    de metales. Finalmente, en los nuevos esquemas de refinacion del petroleo se preve utilizar la coquizacion para aprovechar mejor el ondo de barril. El residuo producto de este proceso, conocido como coque de refineria, tiene un bajo valor comercial, un poder calorifico elevado y un alto contenido de azufre y metales. La gasificacion ha sido desarrollada en las ultimas dos decadas, en los paises altamente industrializados, como una alternativa para la generacion eficiente y limpia de electricidad a partir de combustibles sucios, asi como para la obtencion de ciertos combustibles en lugares donde no se tiene acceso al petroleo, pero si al carbon. Esta tecnologia cumple los reglamentos mas estrictos del mundo en lo que a emisiones contaminantes se refiere y es la unica solucion, junto a los lechos fluidizados, para los problemas que presentan algunos combustibles que son dificiles de quemar con tecnologias convencionales, como el carbon mineral, el coque de petroleo e incluso los residuos liquidos de la refinacion. Con base en los anterior, es posible pensar en la integracion de esta tecnologia a una planta de ciclo combinado para la generacion de electricidad o a una refineria generando vapor, energia electrica, hidrogeno y otros insumos a un costo competitivo, de manera tal que se resuelven los problemas de manejo y almacenamiento de los residuos; por otro lado se maximiza el aprovechamiento de los recursos energeticos primarios en el pais.

El análisis se basó en la teoría fundamentada. RESULTADOS: Existe una franca analogía entre cáncer cervicouterino (CaCu y muerte, una amplia desinformación sobre VPH y displasias y una práctica persistente entre los médicos de no ofrecer información oportuna y clara a las pacientes. Existe una apreciación estigmatizante hacia la infección por VPH que afecta las relaciones cercanas de las mujeres. CONCLUSIÓN: A pesar de la necesidad de las pacientes de obtener información, no la exigen al médico, lo que contribuye a su desconfianza y angustia.OBJECTIVE: To present a relational analysis of how women who are diagnosed with the human papilloma virus (HPV, cervical dysplasia or cervical neoplasia receive or seek information, and how they experience this process within their immediate relationships. MATERIALS AND METHODS: In 2008, 34 qualitative interviews were carried out with women at two Secretary of Health colposcopy clinics in Hermosillo, Sonora. Analysis was based on grounded theory. RESULTS: There is a patent analogy between cervical cancer and death, much disinformation about HPV and dysplasias, and a persistent lack of timely and clear information given to patients by doctors. There is a stigma attached to HPV infection which affects women's immediate relationships. CONCLUSION: Despite patients' need to obtain information, they do not demand it from their doctor, which contributes to their anguish and distrust.

    Full Text Available La terapia génica es una excelente alternativa para el tratamiento de muchas enfermedades. La capacidad para manipular el DNA ha permitido dirigir la terapia génica para corregir la función de un gen alterado, aumentar la expresión de un gen o activar la respuesta inmune. Así, se puede proponer el uso del DNA como un medicamento capaz de controlar, corregir o curar una enfermedad. La terapia génica contra cáncer tiene un potencial enorme, y en la última década se han obtenido resultados muy alentadores del uso del DNA para controlar diversas neoplasias en modelos animales, lo cual ha permitido su aplicación en protocolos experimentales en humanos. Esta revisión concentra una reseña de los fundamentos de la terapia génica y su aplicación en cáncer cervical, desde el punto de vista de las alteraciones de la respuesta inmune enfocadas al microambiente tumoral y el uso de las citocinas como moduladores de la respuesta inmune.Gene therapy is an excellent alternative for treatment of many diseases. Capacity to manipulate the DNA has allowed direct the gene therapy to correct the function of an altered gene, to increase the expression of a gene and to favour the activation of the immune response. This way, it can intend the use of the DNA like medication able to control, to correct or to cure many diseases. Gene therapy against cancer has an enormous potential, and actually the use of the DNA has increased to control diverse cancer in animal models, with very encouraging results that have allowed its applications in experimental protocols in human. This work concentrates a review of the foundations of the gene therapy and its application on cervical cancer, from the point of view of the alterations of the immune system focused on the tumour micro-environment, and the use of the cytokines as immunomodulators.

    Full Text Available Introducción: El cáncer cervical es el segundo cáncer más importante en mujeres a nivel mundial y la segunda causa de muerte en mujeres por cáncer. Se ha demostrado que el proceso de carcinogénesis cervical presenta componentes tanto genéticos, epigenéticos y medio ambientales. En la actualidad, muchos estudios se encaminan en la búsqueda de marcadores moleculares como mutaciones en oncogenes y/o genes tumor supresor que se asocien con la progresión de esta entidad. Los genes candidatos más estudiados en cáncer cervical en distintas poblaciones han sido H-ras, K-ras, EGFR entre otros.Objetivos: Se identificó el virus de papiloma humano (VPH genérico y específico en el ADN libre de plasma y de cepillado cervical de pacientes con cáncer cervical invasivo y con neoplasia intraepitelial cervical (NIC III además de evaluar alteraciones genéticas, como mutaciones en los genes H-ras, K-ras y EGFR.Metodología: Para ello se detectó el VPH genérico mediante PCR con los iniciadores GP5+/GP6+, y específico para VPH 16 y 18 en la región E6/E7. Para detectar las mutaciones en el codón 12 de H-ras, codones 12 y 13 de K-Ras y el exón 21 de EGFR se realizó mediante secuenciación directa de los productos de PCR de estos fragmentos génicos.Resultados: Obteniendo una buena correlación entre las muestras de plasma sanguíneo y los cepillados cervicales, tanto para los hallazgos de VPH p=0.0374 como para las mutaciones evaluadas p=0. En general, para EGFR en el exón 21 no se encontraron mutaciones, al igual que para los codones 12 y 13 en K-ras y codón 12 en H-ras.Conclusión: El uso del ADN presente en el plasma puede ser relevante para el análisis de mutaciones y de la presencia de marcadores tumorales cuando no se dispone de otras muestras.

    in two cluster randomized controlled intervention trials in India. One of these studies is a 4-arm trial addressing the comparative efficacy of VIA, cytology and primary screening with HPV DNA testing. This trial will provide valuable information on comparative detection rates of CIN 2-3 lesions by the middle of 2003. The expected outcomes from the Indian studies will contribute valuable information for guiding the development of public health policies on cervical cancer prevention in countries with different levels of socio-economic and health services development and open up new avenues of research.La India es un país de alto riesgo de cáncer cervical, donde se presentan cerca de la cuarta parte de los casos del total mundial (126 000 casos incidentes y 71 000 muertes durante 2000. La tasa de incidencia estandarizada por edad se encuentra en el rango de 16 a 55 por 100 000 mujeres en diferentes regiones con tasas particularmente altas en áreas rurales. El control del cáncer cervical por detección temprana y tratamiento es una prioridad del Programa Nacional de Control de Cáncer y, desafortunadamente, no hay programas organizados de tamizaje citológico en este país. La infraestructura técnica y financiera para organizar tamizaje en este tipo de cáncer, ha promovido la inspección visual como una potencial alternativa de la citología cervical en la India. Se investigan cuatro tipos de opciones de detección visual de neoplasia cervical: a inspección a ojo desnudo sin la aplicación de ácido acético, opción ampliamente conocida como downstaging; b inspección de ojo desnudo después de la aplicación de ácido acético de 3 a 5% (VIA; c VIA usando un dispositivo de aumento (VIAM; d inspección visual después de la aplicación de yodo-lugol (VILI. Se ha mostrado que el Downstaging ha sido pobremente sensible y específico para detectar neoplasia cervical y no es considerado ampliamente como una prueba de tamizaje conveniente para cáncer cervical.

    Day after day the electric power generation tends to be done in the most efficient way in order to diminish the generation costs and the rate of environmental pollution per KWh generated. This paper discusses the application of absorption refrigeration systems for the cooling of the air entering the compressor of a gas turbine in a combined cycle, in order to increase the mass air flow and with it the turbine output. The flows with remanent energy content that are not used in a combined cycle can be used for the operation of the absorption refrigeration system. This way, the required thermal energy for the cooling system is free. With this system it is possible to raise the gas turbine generation output from 5% to 25%. [Espanol] La generacion electrica dia con dia pretende realizarse de la manera mas eficiente posible con el objeto de disminuir los costos de generacion y la tasa de contaminacion ambiental por Kwh generado. En el presente trabajo se introduce la aplicacion de sistemas de refrigeracion por absorcion para el enfriamiento del aire de entrada al compresor de la turbina de gas de un ciclo combinado, con el objeto de aumentar el flujo masico del aire y con ello la potencia de salida de la turbina. Las corrientes con contenido remanente de energia termica que no se usan en una planta de ciclo combinado pueden servir para operar el sistema de refrigeracion por absorcion. De esta manera, la energia termica requerida para el sistema de enfriamiento es gratuita. Con este sistema es posible incrementar la potencia de generacion de la turbina de gas de 5 a 25%.

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

    The electricity industry traditionally had two thermodynamic cycles for power generation: conventional steam turbine (Rankine cycle) used to supply a base load during the day, and gas turbines (Brayton cycle), for its speed response, normally used to cover peak loads. However, to provide variable peak loads, the gas turbine, as a volumetric machine is affected by the change in air density by changing the combustion temperature. This paper shows the scheme of integration of both systems, that it's known as combined cycle and the different options that would have these power plants, to maintain or increase their power in variable ambient conditions. It analyzes different options, such as: 1. Supplementary fire in the stove. 2. Air cooling intake in the gas turbine (evaporation system or mechanical system). 3. Steam injection in the combustion chamber. [Spanish] La industria electrica tradicionalmente a contado con dos ciclos termodinamicos para generacion electrica: las turbinas convencionales de vapor (ciclo de Rankine) se utilizan para suministrar una carga base durante el dia, y las turbinas de gas (ciclo de Brayton), por su rapidez de respuesta, se utilizan normalmente para cubrir las cargas pico. Sin embargo, para suministrar las cargas variables pico, la turbina a gas, por ser una maquina volumetrica, se ve afectada por el cambio de la densidad del aire de combustion al cambiar la temperatura ambiente. En este trabajo se muestra el esquema de integracion de ambos sistemas, en lo que se conoce como ciclo combinado y las diferentes opciones que tendrian estas plantas de generacion electrica para mantener o incrementar su potencia en condiciones ambiente variable. Para ello se analizan diferentes opciones, tales como: 1.- Combustion suplementaria en el recuperador de calor. 2.- Enfriamiento del aire de admision a la turbina de gas (mediante un sistema de evaporacion o mediante un sistema mecanico). 3.- Inyeccion de vapor a la camara de combustion.

    estudios combinados se hicieron en 77 000 mujeres y dieron como resultado el diagnóstico histológico de más de 1 000 casos de lesiones de alto grado de neoplasia intraepitelial cervical o cáncer. Los métodos utilizados para determinar este virus han sido captura de híbridos de segunda generación (HC2 o la prueba de reacción de polimerasa en cadena (PCR. La prueba del VPH por HC2 en mujeres con diagnóstico citológico de ASC-US HPV han tenido en promedio una muy elevada sensibilidad (90% y especificidad (70%, en comparación con la prueba repetida de citología (sensibilidad 75%, especificidad 60%; y son más sensibles que la colposcopía para seguimiento. Como una prueba adyuvante al Papanicolaou, la rutina de tamizaje con el VPH ha sido un indicador más sensible para identificar lesiones prevalentes de neoplasia intraepitelial cervical de alto grado que la prueba convencional de Papanicolaou o de citología líquida. Una combinación del VPH y citología cervical tiene casi 100% de sensibilidad y valor predictivo negativo. La especificidad de las pruebas combinadas ha tenido sólo una menor especificidad que la observada en citología. Una prueba "doble negativa" del VPH y citología brinda a la mujer un mejor pronóstico en contra del riesgo de desarrollar neoplasia cervical, en comparación con tres pruebas consecutivas de Papanicolaou, y puede brindar seguridad de un nuevo tamizaje en un intervalo de tres años para mujeres de bajo riesgo. Las pruebas para el virus del papiloma humano posiblemente se constituyan en la estrategia más común de tamizaje en programas poblacionales de detección oportuna de cáncer. La investigación continúa para mejorar la sensibilidad y costo-efectividad de métodos de detección de este virus. La captura de híbridos de tercera generación puede brindar la posibilidad de mejorar la tipificación del virus con máquinas de captura rápida mediante robots para asistir la determinación del virus, permitiendo el tamizaje

MATERIAL AND METHODS: The National Cancer Institute of Colombia (NCIC in 2007 developed a Markov model on the natural history of cervical cancer; no screening, conventional cytology, and HPV DNA testing were compared. Only direct costs were used. Outcomes comprise cervical cancer mortality, years of life saved, and lifetime costs. Discounted incremental cost-effectiveness ratios were estimated and sensitivity analyses were conducted for key parameters. RESULTS: Depending on the screening strategy a 69-81% mortality reduction might be expected. The HPV DNA testing every five years is a cost-effective strategy (Incremental Cost-Effectiveness Ratio (ICER: USD$44/YLS if the cost per test is under USD$31. The effectiveness was sensitive to coverage and primarily to follow-up. CONCLUSIONS: HPV DNA testing is a cost-effective alternative for screening in Colombia.

    Full Text Available Bioleaching of sulphide ores using mesophiles microorganisms is an alternative way, economically viable, for certain inexpensive metals recovery. Generally, in these processes some problems become from the direct contact of microorganisms with the ore (deposits, toxicity of ions on the bacteria, etc.. To prevent these troubles, an indirect methodology with the so called bioreactors to generate the leaching medium may be used. These are supports saturated with attached bacteria through which fresh liquid medium is precolated to generate the lixiviant solution. In this paper a two combined bioreactors system is proposed; one of them, previously used, generates oxidant medium through the use of Thiobacillus ferrooxidans and other, introduced in this work, produces sulphuric acid medium using Thiobacillus thiooxidans. This combined system has been used to leach a copper sulphide mineral with an important recovery of the metal. The sulphuric acid producing bioreactor prevented troubles associated with jarosites deposits on the ore, which appear at low pH.

To assess the risk of cervical intraepithelial neoplasia grades 2, 3 or higher (CIN 2/3+ for women with normal cytology and concurrent high-risk human papillomavirus infection (HR-HPV. MATERIAL AND METHODS. We examined 2 200 women every 6 months for an average of 9 years. Cervical smears and samples for HPV DNA were obtained at each visit. Absolute risk of subsequent CIN2/CIN3+ was estimated using the Kaplan-Meier method. RESULTS. The absolute risk of CIN2/CIN3+ among HR-HPV-positive women with normal Pap smear results was 1.06% (95%CI, 0.57-2.20, 5 times higher the risk among all women with normal Pap smears (0.20%; 95%CI, 0.12-0.32 but 7 times lower than that for women with HR-HPV infection and LSIL (7.24%; 95%CI, 3.78-15.2.

    This document proposes a methodology that reunites support tools for the operator of a Combined Cycle Generating Power Station allowing him to identify and to classify gas turbine faults, it also reunites some tools for the generation of action advices in the decision making on the operation maneuvers necessary to counteract the effects caused by faults. We are talking about a system implemented in a power station with the reconfiguration of processes and fault arrangement capacities. For this purpose, the line of exhibition delimits first the existing knowledge on automatic control and operations supervision systems in a CCPP and immediately emphasizes the cracks of the system to let pass to the fault tolerant active control system that will detect faults of the gas and steam turbo-generators of a Combined Cycle Generating Power Plant.

    (conventional or intelligent) is possible to get more power generation than if we use the automatic methods based on feedback MW control. Consequently, the financial benefit due to the MW generated along a period of 2 months, is equivalent to return the investment required if the CCPP would had been repowered. Test also showed that with the fuzzy based SGC is possible to get a 'little more' power generation than if we use the PID based SGC. The development and implementation of the SGC was made in three phases: First Phase: Upgrading of the simulation dynamic mathematical model and implementation in a new software platform based on LabWindows/CVI. Second Phase: Design, implementation and testing of the PID based SGC. Third Phase: Design and implementation and testing of the Intelligent SGC, based in fuzzy logic.

    Full Text Available Although anterior cervical instrumentation was initially used in cervical trauma, because of obvious benefits, indications for its use have been expanded over time to degenerative cases as well as tumor and infection of the cervical spine. Along with a threefold increase in incidence of cervical fusion surgery, implant designs have evolved over the last three decades. Observation of graft subsidence and phenomenon of stress shielding led to the development of the new generation dynamic anterior cervical plating systems. Anterior cervical plating does not conclusively improve clinical outcome of the patients, but certainly enhances the efficacy of autograft and allograft fusion and lessens the rate of pseudoarthrosis and kyphosis after multilevel discectomy and fusions. A review of biomechanics, surgical technique, indications, complications and results of various anterior cervical plating systems is presented here to enable clinicians to select the appropriate construct design.

    Under the expectations of expansion of electric power generation in Mexico, this work exposes the development of a conventional and intelligent generalized supervisory control (CSG) for a combined cycle generation power plant. This one allows to obtain the optimal operation of the power plant through the automatic starting of the generating units and to obtain the maximum possible amount of electrical power in automatic and safe form. For the development of the CSG a control loop by temperature was implemented for the gas turbine system and a control loop by strangled pressure for the gas turbine and a control loop by strangled pressure for the steam turbine. The design of these supervisory systems was made with base in the critical limits on the involved variables of the process: blading average temperature, for the gas turbine (GT) and strangled pressure for the steam turbine (ST) [Spanish] Bajo estas expectativas de expansion de generacion de energia en Mexico, este trabajo expone el desarrollo de un control supervisorio generalizado (CSG) para una central generacion de ciclo combinado.

    Full Text Available Entre los sistemas de refrigeración movidos térmicamente asistidos por energía solar y gas natural, el sistema de refrigeración con eyector ha recibido especial atención. Este sistema se caracteriza por su simplicidad constructiva, ausencia de partes móviles, operación en bajas temperaturas y bajo costo operacional. Sin embargo, el ciclo de refrigeración por eyector tiene usualmente un bajo coeficiente de desempeño. Una alternativa de solución a este problema lo constituye el sistema de refrigeración con eyector combinado. La primera etapa está constituida por un ciclo de compresión mecánica de vapor convencional con R134a, mientras que la segunda etapa la constituye un ciclo termo-movido con eyector usando R141b como fluido de trabajo. Colectores de placa plana y un quemador de energía auxiliar entregan calor al ciclo de eyector. Este artículo describe la simulación en base horaria de un sistema de refrigeración combinado eyector-compresión de vapor asistido por energía solar y gas natural. El sistema de refrigeración solar combinado es modelado usando la herramienta de simulación TRNSYS-EES y los datos climáticos de un año típico de Florianópolis, Brasil. Los resultados obtenidos con la modelación computacional desarrollada para este sistema muestran la ventaja del ciclo de refrigeración combinado eyector-compresión de vapor por sobre el ciclo simple con eyector. Finalmente, el modelo computacional desarrollado en este artículo podría ser usado para realizar una optimización termo-económica del sistema en trabajos futuros.Among the thermally driven cooling systems assisted by solar energy and natural gas, the ejector cooling system has received special attention.

    Percutaneous endoscopic cervical discectomy has evolved as an efficient, minimally invasive spine surgery for cervical disc herniation or radiculopathy. The development of the working channel endoscope makes definitive decompression surgery through a percutaneous approach feasible. There are two methods of approach to target the pathology: anterior and posterior approach. The approach can be determined according to the zone of pathology or the surgeon's preference. The most significant benefits of this endoscopic surgical technique are minimal access tissue trauma and early recovery from the intervention. However, this technique is still evolving and have a steep learning curve. Extensive development of surgical technique and working channel endoscopes will enable us to treat cervical disc herniation more practically. The objective of this review is to describe the cutting-edge techniques of endoscopic surgery in the cervical spine and to discuss the pros and cons of these minimally invasive surgical techniques.

En el grupo 1 se hizo enucleación de 16 ojos (50%, radioterapia externa de uno (3,1%, quimioterapia más termoterapia de 5 (15,6% y quimioterapia más termoterapia más crioterapia de 10 (31,3%. En todos los pacientes se logró preservar al menos un ojo. En el grupo 2, se enuclearon 7 ojos (87,5% y se hizo radioterapia externa más enucleación en un paciente (12.5%. Además, todos los pacientes recibieron quimioterapia. CONCLUSIÓN: la terapia conservadora actual consistente en tratamiento local (termoterapia, crioterapia o braquiterapia y quimiorreducción permite preservar al menos un ojo y en algunos casos de los dos, muchas veces con buena agudeza visual, en niños con retinoblastoma bilateral; se evitan así la enucleación bilateral y la radioterapia externa usada en el tratamiento convencional con todos sus efectos secundarios.

    Objetivos. Examiné los efectos combinados del acceso a la atención primaria mediante el Programa de Salud Familiar (PSF) y las transferencias condicionadas de dinero en efectivo del Programa Bolsa Familia (PBF) sobre la mortalidad infantil posneonatal (MIPN) en Brasil. Métodos. Empleé un análisis ecológico longitudinal usando datos en panel de 4 583 municipios brasileños de 1998 al 2010, con 54 253 observaciones en total. Estimé modelos de regresión de efectos fijos por mínimos cuadrados ordinarios, con la tasa de MIPN como la variable dependiente y el PSF, el PBF y sus interacciones como las principales variables independientes de interés. Resultados. La asociación de una mayor cobertura del PSF con una menor tasa de MIPN se volvió más fuerte conforme aumentaba la cobertura del PBF. En los promedios de todas las demás variables, cuando la cobertura de PBF era 25%, la MIPN predicha fue 5,24 (intervalo de confianza [IC] de 95% = 4,95, 5,53) para una cobertura del PSF de 0%, y de 3,54 (IC de 95% = 2,77, 4,31) para una cobertura del PSF de 100%. Cuando la cobertura del PBF era de 60%, la MIPN predicha fue 4,65 (IC de 95% = 4,36, 4,94) para una cobertura del PSF de 0%, y de 1,38 (IC de 95% = 0,88, 1,89) para una cobertura del PSF de 100%. Conclusiones. El efecto del PSF depende de la ampliación del PBF. Para las poblaciones empobrecidas y subatendidas, la combinación de intervenciones tanto del lado de la oferta como del lado de la demanda podría ser necesaria para mejorar los resultados en salud.

    of the computation, the programming languages and the numerical methods allow to develop mathematical models that simulate in an approximate manner the processes to control, as it is the case of the combined cycle thermoelectric power station and in this way making the evaluation of algorithms of modern control possible. In chapter I a functional description of the steam turbine process is given. Since this belongs to a combined cycle thermoelectric power station, it is begun with the description of this power station, later to emphasize the subsystem of the steam turbine and emphasize each one of the elements that comprise this last one. [Espanol] Este trabajo de investigacion esta orientado a disenar, desarrollar y validar un algoritmo de control moderno, que permita la obtencion de mejores desempenos en el control de velocidad de una turbina de vapor perteneciente a una central termoelectrica de ciclo combinado, en todo el intervalo de operacion, asi como la obtencion de mejores desempenos en el control de la cantidad de megawatts generados por la misma cuando esta acoplada a un generador electrico, comparando el desempeno con el obtenido mediante el controlador convencional existente. Los cambios en la referencia de velocidad o carga, son a solicitud del operador y se dan siempre en forma de rampa, indicando la rapidez con la que se desea efectuar el cambio de valor en la referencia. Esta es la razon por la cual el objetivo principal del control a disenar es realizar un buen seguimiento a referencias del tipo rampa. En el subsistema de la turbina de vapor existente el inconveniente de que las valvulas que regulan el flujo de vapor hacia la turbina, presentan un acoplamiento con la valvula del bypass que permite derivar el flujo de vapor hacia el condensador principal sin tener que pasar por la turbina.

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

    International Nuclear Information System (INIS)

    Rheumatoid cervical myelopathy was studied in 14 patients, clinically, radiographically and by computerized tomography with multiplanar reconstruction (CT/MPR). CT/MPR demonstrated significant unsuspected areas of compromise in 9 of the 14 patients, and altered the surgical procedure in 7 of these 9 patients. CT/MPR clearly identifies all levels of involvement including rotary subluxation. CT/MPR also allows assessment of the spinal nerve canal/foramen and the alignment of the foramina transversaria.

    Full Text Available La acromegalia es una enfermedad poco frecuente producida en más del 95% de los casos por un tumor hipofisario secretor de hormona de crecimiento (GH. Las manifestaciones clínicas están asociadas a síntomas locales por crecimiento del tumor o a las consecuencias orgánicas y metabólicas secundarias a la hipersecreción de GH. Debido a la alta morbilidad y mortalidad asociadas a la acromegalia, un tratamiento individualizado y optimizado para cada paciente es fundamental. Informamos el enfoque terapéutico de nuestro servicio de endocrinología en la atención de 154 pacientes con acromegalia. Utilizando criterios bioquímicos estrictos, con la cirugía logramos un 32% de remisión global, tasa relativamente baja debido fundamentalmente a que la mayor parte de los pacientes presentaban macroadenomas con un alto porcentaje de invasividad local. Con radioterapia complementaria o como tratamiento inicial se logró la remisión en el 65.4% de los pacientes irradiados. El 14.0% de los pacientes controlaron la enfermedad utilizando agonistas dopaminérgicos solos o combinados con otra droga, mientras que aquellos que utilizaron análogos de la somatostatina normalizaron los parámetros bioquímicos en un 45.7% de los casos. En conclusión, con los diferentes tratamientos utilizados obtuvimos el control de la acromegalia en el 55.2% de los casos, esperando optimizar el tratamiento de estos pacientes en la medida en que contemos con y tengamos acceso a nuevas herramientas terapéuticas.

    Full Text Available Background: Breast cancer will develop in one out of ten women during their lifetime. Early diagnosis has increased in recent years. Aim: To describe a population of women with breast cancer stage T1N0M0. To analyze radiation therapy toxicity and to evaluate treatment results. Material and methods: Retrospective review of the medical records of 125 women (aged 35 to 80 years with breast cancer T1N0M0, that were treated between January 1997 and May 2004, with breast conserving surgery and postoperative radiation therapy at an oncology center. Patients lost from follow up were contacted by telephone. Results: An abnormal screening mammography was the reason for consult in 62% of cases. The average tumor size was 11.6 mm. Tumors detected with screening mammogram were smaller than those detected on physical exam. The most common radiotherapy toxicity was erithema, which was severe in 2.5% of cases. No patient had to stop the radiation treatment due to toxicity. One patient developed arm edema. Tamoxifen was prescribed for 5 years to 80% of patients and 17 patients received chemotherapy. After an average follow up of 40 months, no patient has developed local breast relapse, three patients developed contralateral breast cancer and three developed distant metastasis. Two patients died from breast cancer. Disease free survival was 95%. Conclusions: Radiotherapy was well tolerated and had excellent local control. Screening mammography detects small tumors. Survival is excellent for early stage breast cancer

    2016-09-01

    Cervical myelopathy is the most common cause of acquired spinal cord compromise. The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    Treatment-requiring diseases of the cervical spine in children are rare. The most common cases requiring medical assessment and treatment are acute torticollis and various accidents. A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

    Full Text Available En este trabajo se estudia la estabilidad direccional de un vehículo comercial combinado camión-tractor semi-remolque (muy utilizado en Brasil, como función de los parámetros de carga. Para diferentes posiciones del centro de gravedad del conjunto semi-remolque-carga, se obtuvo las curvas que representan los movimientos característicos del vehículo en respuesta a la acción de una perturbación externa. Se calculó también, los factores de amortiguación para estos movimientos durante trayectorias curvas y rectas. Se estudió la influencia de la variación de la carga y del momento de inercia del semi-remolque para las diferentes posiciones del centro de gravedad adoptadas. Los resultados indican cambios significativos en la respuesta dinámica del vehículo con la variación de los parámetros de carga. Se determinó así las condiciones operacionales con menor margen de seguridad para que puedan ser evitadas por los usuarios. Se concluye que existen condiciones de carga que, aunque permitidas por la legislación vigente, deben ser evitadas.This work is about the directional stability of truck-semitrailer vehicle, commonly used in Brazil, as a function of load parameters. For different positions of centre of gravity of semi-trailer, the curves that represent the characteristic movements and the ratio of damping for these movements during curved and straight trajectories are obtained. The influence of load and moment inertia variations for different adopted positions of the centre of gravity of semi-trailer was calculated. The results show significant changes on dynamic response of vehicle with the variations of load parameters. Thus, the operating conditions with less safety margins were determined, so they can be avoided by users. The study allows concluding that there are load conditions that although being accepted by the present legislation, must be avoided.

  3. Cervical metastatic glioblastoma multiforme

    International Nuclear Information System (INIS)

    Glioblastoma multiforme (GBM) is the most common and most malignant primary brain tumour in adults. In spite of the hostile nature of glioblastoma multiforme (GBM), extracranial spread is not a common event. With improving management choices and survival times, reports of extracranial occurrence of GBM have increased. Most commonly these metastases are to the lungs, lymph nodes, neck, skull, scalp, liver, and bones; may be evident on routine follow-up images of the original lesion. Head and neck metastasis of GBM can be debilitating. We present a case of cervical metastasis of GBM and discuss possible mechanisms of extraneural spread of this tumour. (author)

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation. Conservative management was proposed. The patient recovered within 3 weeks from all symptoms. Physicians should be aware that in cases of bevacizumab extravasation, a nonsurgical approach might be effective. PMID:23262983

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    Full Text Available Cervical spondylosis is a common, chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck as well as the contents of the spinal canal. Common clinical syndromes associated with cervical spondylosis include cervical pain, cervical radiculopathy and/or mielopathy. This study show the main principles, indication and side effects of tuina in cervical spondylosis´ treatment; tuina is one of the external methods based on the principles of Traditional Chinese Medicine (TCM, especially suitable for use on the elderly population and on infants. While performing Tuina, the therapist concentrates his mind, regulates his breathing, and actuates the Qi and power of his entire body towards his hands. For a better result is recommended to try to combine acupuncture with tuina treatment. Tuina can help relieve the pain associated with spondylosis. After this kind of treatment, the symptomes produced by irritated nerves and sore muscles can find some relief. Tuina helps patients with cervical spondylosis regain muscle control, nerve function and flexibility, all through the restoration of the life force flow.

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    Full Text Available Abstract Background Assessment of sensorimotor function is useful for classification and treatment evaluation of neck pain disorders. Several studies have investigated various aspects of cervical motor functions. Most of these have involved slow or self-paced movements, while few have investigated fast cervical movements. Moreover, the reliability of assessment of fast cervical axial rotation has, to our knowledge, not been evaluated before. Methods Cervical kinematics was assessed during fast axial head rotations in 118 women with chronic nonspecific neck pain (NS and compared to 49 healthy controls (CON. The relationship between cervical kinematics and symptoms, self-rated functioning and fear of movement was evaluated in the NS group. A sub-sample of 16 NS and 16 CON was re-tested after one week to assess the reliability of kinematic variables. Six cervical kinematic variables were calculated: peak speed, range of movement, conjunct movements and three variables related to the shape of the speed profile. Results Together, peak speed and conjunct movements had a sensitivity of 76% and a specificity of 78% in discriminating between NS and CON, of which the major part could be attributed to peak speed (NS: 226 ± 88 °/s and CON: 348 ± 92 °/s, p Conclusions Peak speed of fast cervical axial rotations is reduced in people with chronic neck pain, and even further reduced in subjects with concomitant low back pain. Fast cervical rotation test seems to be a reliable and valid tool for assessment of neck pain disorders on group level, while a rather large between subject variation and overlap between groups calls for caution in the interpretation of individual assessments.

    The thermoelectric centrals of the combined cycle type (Brayton Cycle and Rankine Cycle) present a series of opportunities to increase the efficiency of the combined cycle or of the generated power. This paper shows the methodology for the performance of energy balances in a heat recuperator (H. R.), typically employed in the combined cycle stations operating in Mexico, for the assessment of the energy harnessing in the different sections conforming a H. R. The effect of the installation of evaporative coolers and/or an absorption cooling system at the gas turbine compressor intake on the steam generation in the heat recuperator, is evaluated. This extra generation of steam is quantified for its potential use in the same absorption refrigeration system. From the assessment, it follows up that the steam generation in the H.R. is inversely proportional to the ambient temperature and that, although the increased amount of steam generated can not be harnessed in total by the steam turbine, the remaining fraction is good enough to cover the heat demand for the operation of the refrigeration system.

    Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark......, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented...... cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT...

    Full Text Available Background: In multilevel spinal cord compression caused by cervical spondylosis, surgeonsface the choice of performing a posterior route as a laminectomy orlaminoplasty, or an anterior route as multiple adjacent interbody decompressionsor corpectomies. The anterior cervical operation is not considered bysome clinicians because of concerns about complications and the complexityof multilevel anterior cervical surgery.Methods: In this retrospective study, 14 patients with multilevel cervical spondylosiswho were operated on via an anterior route were enrolled to evaluate thecomplexity, safety, and clinical results. The collected parameters were operationtime, blood loss, hospital days, and early and late complications forevaluating the operative complexity, radiographic follow-up for evaluatingfusion, graft problems, implants problems, and the recovery rate using theJapanese Orthopaedic Association score (JOA score for evaluating the operativeresults.Results: The mean operation time was 363.4 min, and blood loss was 431.4 ml. Anearly complication was noted in 1 patient with combined deep vein thrombosisand a pulmonary embolism. Late complications were screw breakage in1 patient and screw loosening in 5 patients. The mean duration of follow-upwas 21.9 months. The mean recovery rate of the JOA score was 38.8% postoperativelyand 51.9% at the final follow-up. The fusion rate was 100% inthis series.Conclusions: Anterior cervical decompression and fusion for multilevel stenosis requires alonger operation time than posterior procedures; however, the clinical resultsare satisfactory.

  3. Analysis of digitized cervical images to detect cervical neoplasia

    2004-05-01

    Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

    Today we can state that in spite of a considerable number of cervical osteochondrosis studies, there is a lack of research devoted to analysis of its course. There is no correlation between initial expert evaluations of cervical osteo-chondrosis cases and further course of pathological process. Goal of the research is to develop system of course prognosis of cervical osteochondrosis taking into account environmental infuence, heredity, living conditions, psychological profle of patient’s personality. Materials and methods. Dynamics of degenerative-dystrophic changes progressing of cervical vertebrae in 236 patients was analyzed. Results. Received data demonstrated that probability of stage I changing to stage II, III and IV depended on patients’ sex, age and type of labour activity, frequent supercooling and stress. Probability of fast progression of cervical osteochondrosis (5-year cycle of stage I changing to stage III and IV was to a great extent associated with heredity, urban living, presence of endocrine system diseases, syndrome of nonspecifc dysplasia of connective tissue and low indices of quality of life. Conclusion. Proposed system allows making prognosis of morphologic changes in spinal cord, and is based on radiation methods of verifcation without taking into consideration dynamics of neurological symptomatology.

    Full Text Available Presentamos nuestra experiencia en el tratamiento de los queloides mediante resección quirúrgica y radioterapia inmediata posterior. La radioterapia transforma el queloide en un tejido hipocelular, hipovascular e hipóxico, impidiendo la excesiva migración de fibroblastos. Si se administra la dosis adecuada de radiación, se consigue un equilibrio entre la formación de cicatriz y la proliferación excesiva de tejido, evitando la formación de queloide, sin impedir la cicatrización normal. Nuestro protocolo se divide en dos fases: la primera consiste en la exéresis del queloide mediante una incisión que sigue el trayecto del mismo, con un cuidadoso cierre en dos planos siendo siempre el superficial una sutura intradérmica. La segunda fase será la radioterapia, con dos modalidades posibles de tratamiento: 1- Braquiterapia (tratamiento a corta distancia, requiere la colocación de un catéter bajo la sutura, a través del cual se introduce una fuente radiactiva, normalmente Ir192. Se emplea especialmente en heridas longitudinales. 2- Radioterapia externa con electrones de baja energía. Se emplea en heridas complejas o extensas. Generalmente, dosis de 20 Gy. en 4 fracciones de 500 cGy, ofrecen excelentes resultados con mínimas secuelas o efectos secundarios. El volumen blanco debe incluir la herida quirúrgica más un margen de 4 mm. alrededor de ella. Con este procedimiento, hemos observado unos excelentes resultados, con un índice de recidivas inferior al 4%, y una mejora en los síntomas clínicos en el 100% de los casos. Como efectos secundarios observamos telangiectasias (15,4 % o cambios en la pigmentación cutánea (5,9%.We present our experience in treatment of keloid scars with surgical resection and immediately postoperative radiotherapy.

    Full Text Available Background: Enlarged palpable cervical lymph nodes as a primary presenting sign are very common and may be due to inflammatory lesions and tumors. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. In patients presenting with cervical lymphadenopathy, excision biopsy provides material to establish an early diagnosis. We designed this study in our population for histological evaluation of cervical lymph node biopsies that might be important in the management of these patients. Objective: Histopathological evaluation of different diseases involving the cervical lymph nodes in relation to age and sex of the study population. Materials and Methods: It was a cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. A total of 107 patients were evaluated for specific cause of cervical lymphadenopathy in relation to age and sex. Lymph node biopsies of all patients of both sexes and all age groups were included in the study. Results: Among the 107 subjects 58 (54.2% were males and 49 (45.8% were females with a male to female ratio of 1.2:1. The age of the patients ranged from 2 to 85 years with a mean age of 32.68 ± 18.01 years. Of the 107 lymph node biopsies, 34 cases (31.8% were reactive lymphadenitis, 41 cases (38.3% were tuberculosis, 2 cases (1.9% were non-caseous granuloma, 6 cases (5.6% were Hodgkin lymphoma, 8 cases (7.5% were non-Hodgkin lymphoma, 12 cases (11.2% were metastatic neoplasm and 4 cases (3.7% were other specific lesions. Conclusion: The commonest cause of cervical lymphadenopathy was tuberculosis, followed by reactive lymphadenitis, lymphoma and metastatic neoplasm.

    Full Text Available Durante el tratamiento de un residual coloreado se debe prestar atención a la reducción o eliminación del color, contribuyendo de esta forma a reducir el impacto sobre los ecosistemas donde son vertidos. En Cuba se tienen numerosas experiencias del tratamiento de la vinaza de destilería por vía anaerobia, obteniéndose buenos valores de remoción de la carga orgánica, pero permanecen inalterables compuestos de difícil biodegradabilidad-biodisponibilidad y el color. En el presente trabajo se estudia el tratamiento anaerobio metanogénico, empleando un lodo granular y posterior tratamiento aerobio, con el hongo Pleurotus sp.; para la reducción del color y de la DQO de este residual agresivo. Para el desarrollo experimental se utilizó un reactor anaerobio UASB de 1,5 L y los ensayos aerobios se realizaron en erlenmeyer de 500 mL. Se estudió la influencia de la adición de los componentes nutricionales de un medio sintetico, para propiciar la decoloración de la vinaza. Se siguió la remoción del color mediante la determinación de la luminancia, además de determinarse los valores de DQO al inicio y final de cada tratamiento. Como resultado del estudio se obtuvo que el tratamiento anaerobio es efectivo para remover mas del 80 % de la carga orgánica de la vinaza, aun cuando esta se trata sin diluir, pero no reduce de manera significativa el color el cual se mantiene más del 95 %. Sin embargo, si se acopla un tratamiento aerobio con el hongo Pleurotus spp. el color se reduce por encima del 80 % y disminuye aun más el valor de DQO, a valores por debajo de los 5 g/l. Para el tratamiento con el hongo se requiere la adición de una fuente carbonada externa para favorecer la decoloración. Como resultado del trabajo se concluye que se requiere de la combinación de un tratamiento aerobio, además de la digestión anaerobia, para lograr la decoloración de la vinaza favoreciendo la remoción de la DQO, siendo el tratamiento con Pleurotus una

    Background Lower cervical dislocation with locked facets is common in cervical injury. The locked facets include unilateral and bilateral types. Different successful closed reduction rates has been achieved between unilateral and bilateral types by using rapid skull traction, which was commonly used to reduce the cervical dislocation. It is important to investigate a suitable management specific to patients with different types of cervical locked facets.Methods A total of 38 patients with cervical dislocation with locked facet due to cervical injury treated by rapid skull traction and operation from 1988 to 2005 were reviewed. Rapid skull traction was used in all the patients. Successful closed reduction rate was 88.0% in patients with bilateral cervical locked facets and that was 15.4% in those with unilateral cervical locked facets. These data were then statistically compared by Chi-square test. Patients who were reduced successfully underwent anterior cervical discectomy and fusion at the injured level, and those who failed in closed reduction received posterior open reduction and fixation.Results In this series, there was statistically significant difference (P<0.05) in the rate of successful closed skull traction reduction between unilateral and bilateral locked facets dislocation. Unilateral cervical locked facets dislocation was not easily reduced by skull traction which was suitable for reduction of bilateral cervical locked facets dislocation. However,unilateral cervical locked facets dislocation can be reduced by posterior open reduction.Conclusions Unilateral cervical locked facets dislocation should be treated immediately with posterior open reduction and instrumentation. Bilateral cervical locked facets dislocation can be reduced by rapid skull traction firstly and anterior cervical discectomy and interbody fusion later.

Se estudiaron 15 niños del subtipo hiperactivo/impulsivo y 15 del combinado del TDAH a los que se les realizó un electroencefalograma en vigilia. Los principales hallazgos al electroencefalograma fueron el incremento de la actividad lenta frontal y la presencia de descargas epileptiformes en ambos grupos. Se encontraron diferencias significativas entre los espectros de frecuencia de ambos grupos, por exceso en las bandas lentas y por defecto en las rápidas en el hiperactivo/impulsivo respecto al combinado. Estos resultados respaldan el modelo de un déficit de maduración del Sistema Nervioso Central como base del TDAH.Electroencephalographic studies in children with Attention Deficit Hyperactivity Disorder (ADHD report specific profiles in different subtypes. This study investigated the presence of Electroencephalogram abnormalities within a sample of children with the Hyperactive-Impulsive and combined subtypes of the disorder. Subjects consisted of 15 children of hyperactive-Impulsive and 15 children of combined subtypes. Electroencephalogram was recorded during an eyes closed resting condition. The principal findings were characterized by increased slow wave activity in frontal area and the visual analysis showed epileptiforms abnormalities in both groups. There was statistic difference in the spectrum of frequency in both subtypes characterized for more slow activity and less rapid activity in the hyperactive-Impulsive subtipe. These results support a model of ADHD resulting from a maturational lag in the Central Nervous System.

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

    Cervical spine injuries of children, though rare, have a high morbidity and mortality. The pediatric cervical spine is anatomically and biomechanically different from that of adults. Hence, the type, level and outcome of cervical spine injuries in children are different from those seen in adults. Normal developmental variants seen in children can make evaluation of the pediatric cervical spine challenging. This article reviews the epidemiology of pediatric cervical spine trauma, normal variants seen in children and specific injuries that are more common in the pediatric population. We also propose an evidence-based imaging protocol to avoid unnecessary imaging studies and minimize radiation exposure in children. (orig.)

    Lectin binding in the walls of large to medium-sized blood vessels and lymphatics in the rat thoraco-cervical region was examined histochemically. The tunica intima of the aorta and superficial cervical artery showed positive reactions with wheat germ agglutinin (WGA) and Concanavalin A (ConA) but not with Dolichus biflorus agglutinin (DBA). The tunica media of the aorta exhibited intense WGA binding, especially on the smooth muscle cells, but the tunica media of the superficial cervical artery did not react with the lectin. Neither ConA nor DBA bound to the tunica media of the aorta and superficial cervical artery. The tunica adventitia of both arteries contained sites binding the three lectins, although DBA reactivity declined as the vascular diameter decreased. The tunica intima of the superior vena cava and azygos vein exhibited positive WGA and ConA binding, whereas DBA binding was noted on only part of the tunica intima of the superior vena cava and not on that of the azygos vein. The tunica media and tunica adventitia were reactive for all three lectins. The WGA and ConA binding sites in the tunica adventitia showed loose networks, suggesting lectin binding on connective tissue elements interlacing among smooth muscle bundles. Lectin binding sites in the walls of lymphatics exhibited an arrangement similar to those in the walls of the veins. Moreover valves protruding into the lumen showed intense WGA and ConA binding and scattered DBA binding. Three other lectins (Ulex europaeus agglutinin, peanut agglutinin, Maclura pomifera) were examined, but they showed no reactions with the vessels. Thus, the differential binding of lectins on the walls of blood vessels and lymphatics of various sizes suggests the functional complexity of monosaccharide residues in the vascular walls.

    Full Text Available O arroz é classificado como uma planta tolerante ao amônio (NH4+ devido à predominância desse íon nos solos alagados. Entretanto, nas regiões oxidadas do solo e da rizosfera do arroz pode haver a formação de nitrato (NO3- e esta se tornar importante fonte de N para cultura. Este trabalho foi conduzido com o objetivo de avaliar o efeito de diferentes proporções entre os íons NH4+ e NO3- no desenvolvimento do arroz em solução nutritiva. O experimento foi realizado em casa de vegetação no período de janeiro a fevereiro de 2008, em solução nutritiva com as seguintes proporções entre NH4+ e NO3-: 100:0, 75:25, 50:50, 25:75 e 0:100 na concentração de 5,0 mmol L-1 de N. Foi cultivado o genótipo IRGA 417 e avaliado o rendimento de biomassa, os teores de N, K, Ca e Mg na biomassa e na seiva do xilema. Houve toxidez por NH4+ nas proporções de 100:0 e 75:25 e por NO3- nas proporções de 25:75 e 0:100. Na proporção de 50:50 as plantas se desenvolveram normalmente. O suprimento combinado de NH4+ e NO3- aumentou a produção de biomassa em relação ao NH4+ e ao NO3- supridos isoladamente. O NH 4+ na solução reduziu os teores de Ca e Mg na biomassa, porém não influenciou o teor de N e o de K. Já na seiva do xilema houve redução nos teores de K, Ca e Mg, indicando que o NH4+ influenciou na absorção desses cátions. A quantidade total absorvida de N, K, Mg e Ca foi maior com o suprimento combinado de NH4+ e NO3-, indicando que, além de promover melhor desenvolvimento das plantas de arroz, aumenta a eficiência de absorção de nutrientes em relação ao suprimento isolado das duas formas de N.

  12. Myelopathy hand in cervical radiculopathy

    International Nuclear Information System (INIS)

    The so-called 'myelopathy hand', or characteristic finger paralysis, often recognized in cervical compression myelopathy, has been considered a unique manifestation of cervical myelopathy. We used our original grip and release test, a 15-second test in which finger motion is captured with a digital camera, to investigate whether cervical radiculopathy has the same characteristics as myelopathy hand. Thirty patients with pure radiculopathy, id est (i.e.), who had radiating arm pain and evidence of corresponding nerve root impingement on X-ray images or MRI scans, but did not have spinal cord compression, served as the subjects. In contrast to other radiculopathies, C7 radiculopathy was manifested by a significant reduction in the number of finger motion cycles on the affected side in comparison with the unaffected side, the same as in myelopathy hand. Uncoordinated finger motion was significantly more frequent on the affected side in C6 radiculopathy than on the unaffected side. These findings contradict the conventional notion that myelopathy hand is a unique manifestation of cervical myelopathy, but some radiculopathies manifested the same kinds of finger paralysis observed in myelopathy hand.

    2016-05-01

    Cervical radiculopathy describes pain in one or both of the upper extremities, often in the setting of neck pain, secondary to compression or irritation of nerve roots in the cervical spine. It can be accompanied by motor, sensory, or reflex deficits and is most prevalent in persons 50 to 54 years of age. Cervical radiculopathy most often stems from degenerative disease in the cervical spine. The most common examination findings are painful neck movements and muscle spasm. Diminished deep tendon reflexes, particularly of the triceps, are the most common neurologic finding. The Spurling test, shoulder abduction test, and upper limb tension test can be used to confirm the diagnosis. Imaging is not required unless there is a history of trauma, persistent symptoms, or red flags for malignancy, myelopathy, or abscess. Electrodiagnostic testing is not needed if the diagnosis is clear, but has clinical utility when peripheral neuropathy of the upper extremity is a likely alternate diagnosis. Patients should be reassured that most cases will resolve regardless of the type of treatment. Nonoperative treatment includes physical therapy involving strengthening, stretching, and potentially traction, as well as nonsteroidal anti-inflammatory drugs, muscle relaxants, and massage. Epidural steroid injections may be helpful but have higher risks of serious complications. In patients with red flag symptoms or persistent symptoms after four to six weeks of treatment, magnetic resonance imaging can identify pathology amenable to epidural steroid injections or surgery.

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

    The aim of this study was to describe the method and the value of cervical discography as correlated with the MR findings. Twenty-one discs in 11 consecutive patients who underwent cervical discography were analyzed. MR and CT discography (CTD) were performed in all patients. Discography was performed after swallowing barium for visualizing the pharynx and the esophagus to prevent penetration. We also analyzed the preceding causes of the subjects' cervical pain. The results of the pain provocation test were classified into concordant pain, discordant pain and a negative test. MRI was analyzed according to the T2-signal intensity (SI) of the disc, disc height, annular bulging and disc herniation. The CTD was analyzed for degeneration or radial tear of the disc, epidural leakage of the contrast agent and pooling of the contrast agent at the periphery of the disc. The pain provocation tests were correlated with the MR and CTD findings. We used the chi-square test to analyze the results. Concordant pain was observed in 14 cases, discordant pain in 3 cases and there were negative tests in 4 cases. There were no complications related to the procedure. Four patients had undergone anterior cervical fusion and four patients that developed after traffic injuries. The decreased T2-SI and annular bulging on MRI, disc degeneration and peripheral pooling of the contrast agent on CT were significantly correlated with pain provocation. When the diagnosis of disc disease is difficult with performing MRI, cervical discography with using swallowed barium solution to reduce the penetration of the esophagus or hypopharynx may play be helpful. The decreased T2-SI and annular bulging on MRI correlated significantly with a positive result on the pain provocation test.

    extra space and expenses implied in the use of repeated devices. The design of the system was carried out by using the structural analysis (SA) which is a tool based on graph theory and computer science. The SA allowed the analysis of monitorability, detectability and isolability properties of the process, besides it provides the computation sequence of non monitored (unknown) variables in order to obtain the analytical redundancy relations. To validate the fault diagnosis system, the detection and isolation algorithms were programmed in C language and integrated to the simulator software of a CCPP in LabWindows CVI. In order to provide a way to easily identify the existence of a fault, a graphic interface was developed, where the faulty component, sensor or actuator is indicated. [Spanish] Debido a la naturaleza fisica de sus componentes, todos los procesos tecnologicos son susceptibles de falla. Estas fallas afectan el funcionamiento del sistema, provocando desde una reduccion en su desempeno hasta cuantiosas perdidas economicas y en el peor de los casos desastres ambientales y humanos. La deteccion oportuna de la presencia de las fallas ayuda a tomar acciones correctivas y como consecuencia a reducir el dano potencial que estas ocasionan. Para realizar la tarea de deteccion de fallas, los procesos tecnologicos cuentan con sistemas de monitoreo y alarmas que se activan si algunas de las variables monitoreadas rebasa un umbral establecidos. El metodo presenta el inconveniente de que ante la presencia de una sola falla se pueden activar varias alarmas, lo que dificulta la tarea para localizar al elemento danado. Ademas, se basa en la redundancia fisica, que consiste en el uso de elementos repetidos para realizar una misma tarea. Las centrales de generacion de ciclo combinado (CGCC) son procesos de gran escala con alto grado de susceptibilidad a fallas, a causa de las condiciones estrictas en las que operan y del gran numero de componentes que contienen, incluyendo

    Full Text Available AIM: To evaluate the role of parity, Bishop score, cervical length by transvaginal ultrasound in predicting the induction to delivery interval. METHODS AND MATERIALS: It is a prospective study done at Government general Hospital, Kurnool, Andhra Pradesh, India over a period of one year from August 2008 to July 2009. Hundred pregnant women with 37 to 42 weeks of gestation who underwent induction of labour for different indications were taken. Their parity according to obstetric history, Bishop Sco re followed by cervical length in centimeters by transvaginal ultrasound was assessed in all patients. RESULTS: Among the hundred pregnant women 57 were primigravidae, they had mean induction delivery interval of 17 hours and 18 minutes. Multigravidae were 43, they had 11 hours 45 minutes mean induction delivery interval. Bishop score of 5 and cervical length by transvaginal ultrasound of 2.8 cm were considered as cutoff values. Bishop score ≤5, cervical length above >2.8cm were considered unfavorable. Among total 100 women, 76 women had Bishop score ≤5, in them 16 hours 12 minutes mean induction delivery interval was noted. Bishop score >5 was noted in 24 women who had 13 hours and 10 minutes mean induction to delivery interval. When cervical length was cons idered, among total 100 women, 45 women had cervical length >2.8 cm , in them mean induction to delivery interval was 21 hours and 4 minutes, whereas 55 women had cervical length ≤2.8cm in them mean induction to delivery interval was 11 hours and 2 minutes. CONCLUSION: All the three parameters i.e. Parity, Bishop score and cervical length by transvaginal ultrasound are having significant predictability towards induction to delivery interval. Out of these three parameters parity and cervical length are having independent predictability.

    Background It was reported that telomerase expression is closely associated with cellular immortality and cancer. This study was designed to investigate the relationship between telomerase expression and the carcinogenesis of cervical cancer, the possible use of telomerase as a marker of cervical intraepithelial neoplasia (CIN) progression or regression, and the natural history of CIN. Methods Telomeric repeat amplification protocol (TRAP) assay was used to measure telomerase activity in cervical scrapings and biopsy samples obtained from 105 cases affected with various cervical conditions, including chronic cervicitis (n=20), CIN (n=64, 16 cases of CIN Ⅰ , 20 cases of CIN Ⅱ, and 28 cases of CIN Ⅲ ), and invasive squamous cell carcinoma (n =21 ).Results In exfoliated cell samples, telomerase activity was detected in 5 of 20 (25. 0% ) cases of cervicitis, 10 of 16 (62.5%) cases of CIN Ⅰ , 11 of 20 (55.0%) cases of CIN Ⅱ, 23 of 28 (82.1%) cases of CIN Ⅲ, and 13 of 21 (61.9%) cases of carcinoma. In cervical biopsy samples, telomerase activity was detected in 6 of 20 (30. 0%) cases of cervicitis, 8 of 16 (50. 0%) cases of CIN Ⅰ , 9 of 20 (45.0%) cases of (CIN Ⅱ, 27 of 28 (96. 4%) cases of CIN Ⅲ, and 20 of 21 (95. 2%) cases of carcinoma. Telomerase activation was significantly higher in CIN samples than in cervicitis samples. Telomerase activity was detected at similar frequency in samples from cervical scrapings and cervical biopsies.Conclusion These results seem to suggest that telomerase expression may be associated with carcinogenesis of the cervix. TRAP assay of cervical scraping samples could be used to monitor and predict the development of CIN in clinical practice.

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

    Despite the development of screening and of a vaccine, cervix cancer is a major cause of cancer death in young women worldwide. A third of women treated for the disease will recur, almost inevitably leading to death. Functional imaging has the potential to stratify patients at higher risk of poor response or relapse by improved delineation of disease extent and tumor characteristics. A number of molecular imaging biomarkers have been shown to predict outcome at baseline and/or early during therapy in cervical cancer. In future this could help tailor the treatment plan which could include selection of patients for close follow up, adjuvant therapy or trial entry for novel agents or adaptive clinical trials. The use of molecular imaging techniques, FDG PET/CT and functional MRI, in staging and response assessment of cervical cancer is reviewed. PMID:26859085

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

    Full Text Available Several studies have shown that isocaloric diets have different effects on satiety. The aim of the present study was to compare the effect of lunches with different glycemic indexes (GI in type 2 diabetics. Ten men and women with type 2 diabetes participated in the study. Subjects were given two experimental lunches with glycemic indexes of 43 and 88. Visual analogue rating scales were completed before and after each experimental meal periodically to record subjective feelings of satiety. Satiety Area Under the Curve was 1024 ± 160 mm after the low GI diet and 711 ± 190 mm after the high GI diet. Eating a lunch with a low GI index resulted in higher satiety perception. These results suggest the need to promote culturally based combined foods with high fiber and low GI. This approach might contribute to the prevention of obesity by increasing the perception of satiety while also improving metabolic control of diabetics. In addition, this is a low cost approach for people with limited financial resources.Diversos estudios han demostrado que las dietas hipocalóricas tienen diferentes efectos sobre la saciedad.

    Forty-three patients operated for cervical myelopathy were examined with a 1.5 T magnetic resonance imaging. Cord compression was demonstrated directly on the sagittal image in cases of cervical disc herniation, cervical spondylosis and O.P. L.L. Herniated disc material was seen positive on axial image. But factors of cord compression in cases of cervical spondylosis and O.P. L.L. were not clearly confirmed, so additional examinations such as myelogram, tomogram and CT was needed. (author).

    2013-01-01

    Full Text Available In case of invasive cervical carcinoma several molecular events were reported and these molecular events resulting in multiple genetic abnormalities. In order to control these tumors multiple molecular therapeutic targets are needed with different molecular mechanisms. Unfortunately, these molecular targets were in early stages of development. Because of less degree of success of conventional therapeutics for late stages of cervical cancer and lowering of prognosis of patients there is an increase in interest for the development of potential therapeutic targets for cervical cancer. This review article emphasizes the current molecular targeted agents; with special attention to estrogen receptors for human papilloma virus infected cervical cancer.

    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.

    2014-12-01

    Conclusion: Cervical laminoforaminotomy is an effective technique in addressing multisegmental cervical radicular compression. Moreover, this technique eliminates the need of fusion and possible internal fixation, which are essential if the alternative anterior procedure was performed; thus, reducing the overall cost and morbidity.

  3. Sport injuries of the cervical spine

    International Nuclear Information System (INIS)

    The article reports on injuries of the cervical spine occurring during sports activities. An attempt is made to reconstruct the movements which led to the cervical spine injuries in question. In two cases of accidents occuring during bathing, one football accident and a toboggan accident, the injuries concerned point to hyperextension of the cervical spine as cause of the injury. In another football accident and a riding accident, the changes observed allow us to conclude that the movement leading to the injury must have been a hyperflexion. One accident occurring while jumping on the trampolin resulted in an injury of the upper cervical spine pointing to the action of a compressive force on the cervical spine in addition to the force resulting in hyperflexion.

    2012-02-01

    The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970\\'s. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review.

    2008-01-01

    Cervical arthroplasty after anterior decompression with insertion of a prosthetic total disc replacement has been suggested as an alternate to anterior cervical fusion. It develops quickly during recent years. Currently there are several cervical arthroplasty devices. Each device varies in terms of materials, range of motion and constraint. Early studies suggest that in the short term, the complication rate and efficacy is no worse than fusion surgery. Long-term results have not yet been reported. This review examines the current prostheses as well as discussing issues regarding indications and technique. It is hoped that an improvement of cervical arthroplasty occurs in terms of materials and design as spinal surgeons enter a new dines of the management of cervical spine disease.

    BACKGROUND: The Faroe Islands have had nationally organised cervical cancer screening since 1995. Women aged 25-60 years are invited every third year. Participation is free of charge. Although several European overviews on cervical screening are available, none have included the Faroe Islands. Our...... aim was to provide the first description of cervical cancer screening, and to determine the screening history of women diagnosed with cervical cancer in the Faroe Islands.

    2016-01-01

    We describe three patients with misdiagnosed unstable fractures of the cervical spine, who were treated conservatively and developed kyphotic deformity, myelopathy, and radiculopathy. All three patients were then managed with closed reductions by crown halo traction, followed by instrumented fusions. Their neurologic function was regained without permanent disability in any patient. Unstable fractures of the cervical spine will progress to catastrophic neurologic injuries without surgical fixation. Posttraumatic kyphosis and the delayed reduction of partially healed fracture dislocations by preoperative traction are not well characterized in the subaxial cervical spine. The complete evaluation of any subaxial cervical spine fracture requires CT scanning to assess for bony fractures, and MRI to assess for ligamentous injury. This allows for assessment of the degree of instability and appropriate management. In patients with delayed posttraumatic cervical kyphosis, preoperative closed reduction provided adequate realignment, facilitating subsequent operative stabilization. PMID:26321304

    Fransen, P

    2014-10-01

    Cervical spondylotic myelopathy (CSM) is a common condition. Uninstrumented laminectomy may be complicated by postoperative instability, whereas anterior or posterior decompression with fusion may be associated with stiffness and adjacent segment disease. Cervical laminoplasty, initially oriented towards pediatric patients and ossification of the posterior longitudinal ligament, becomes an interesting surgical alternative to decompress and reconstruct cervical anatomy without fusion. Eighteen patients (12 men, 6 women), mean age 64.2 who presented with CSM were treated surgically using multilevel laminoplasty, and reviewed after 1 month, 6 months, 1 year and 2 years. Clinical evaluation was performed based on the Benzel-JOA and Nurick scores. The preoperative mean Benzel-JOA score was 13.55; Preoperative mean Nurick score was 1.88. Preoperative MRI was carried-out in 16/18 patients. Intramedullary hyperintensity in T2 was observed in 6 patients. The operation was performed on 2 levels (4 patients) 3 levels (11 patients) and 4 levels (3 patients). We used the open-door hinged laminoplasty technique, using metallic implants, without bone graft. At one month FU, mean JOA score was 15.44, and Nurick dropped to 1.05. At 6 months, mean JOA was 16.28 and Nurick was 0.71. At one year, the mean JOA score was 16.16, and Nurick was 0.83. At 2 years, mean JOA was 17.5, and Nurick was 0.25. One infection, one dural tear and one transient episode of C5 paresthesia were observed. We conclude that spinal cord decompression by open-door laminoplasty for CSM allows significant clinical improvement observed progressively in the two years following surgery. PMID:25239380

    Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated. PMID:6529877

    Full Text Available Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years. Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%. On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

  16. Diagnosis of cervical disc disease

    International Nuclear Information System (INIS)

    High resolution CT easily localized lesions including soft tissues of the bone such as disc protrusion and thickening of the yellow ligament. In all cases, myelography demonstrated compression of the nerve roots of the spinal cord which corresponded to CT findings at the level where plain CT revealed a lesion. However, CT metrizamide myelography demonstrated the lesion more clearly than did conventional myelography. CT metrizamide myelography also outlined compression of the nerve roots satisfactorily and demonstrated compressed findings of the spinal cord in the dynamic study. Thus, high resolution CT was useful for screening of cervical disc disease, and CT metrizamide myelography, for identification of lesions of the nerve roots. (Chiba, N.)

    Objective:To measure the expression pattern ofSTAT2 in cervical cancer initiation and progression in tissue sections from patients with cervicitis, dysplasia, and cervical cancer. Methods:Antibody against humanSTAT2 was confirmed by plasmids transient transfection andWestern blot.Immunohistochemistry was used to detectSTAT2 expression in the cervical biopsies by using the confirmed antibody againstSTAT2 as the primary antibody.Results:It was found that the overall rate of positiveSTAT2 expression in the cervicitis, dysplasia and cervical cancer groups were38.5%,69.4% and76.9%, respectively.TheSTAT2 levels are significantly increased in premalignant dysplasia and cervical cancer, as compared to cervicitis(P<0.05). Noticeably,STAT2 signals were mainly found in the cytoplasm, implying thatSTAT2 was not biologically active.Conclusions:These findings reveal an association between cervical cancer progression and augmentedSTAT2 expression.In conclusion,STAT2 increase appears to be an early detectable cellular event in cervical cancer development.

    Cervical spinal cord injury is a rare but serious complication after general anesthesia. The risk factors include traumatic cervical injury, cervical spine instability, and difficult airway management. It has also occurred in the absence of cervical instability. Here we report a patient who had a history of intermittent neck pain without numbness. Preoperative radiologic examinations showed degenerative changes in the cervical spine. She developed progressive tingling and numbness in her limbs after thyroidectomy under general anesthesia.

    2013-01-01

    Persistent infection with high-risk types of human papillomavirus(HPV) is known to cause cervical cancer; however,additional genetic and epigenetic alterations are required for progression from precancerous disease to invasive cancer.DNA methylation is an early and frequent molecular alteration in cervical carcinogenesis.In this review,we summarize DNA methylation within the HPV genome and human genome and identify its clinical implications.Methylation of the HPV long control region (LCR) and L1 gene is common during cervical carcinogenesis and increases with the severity of the cervical neoplasm.The L1 gene of HPV16 and HPV18 is consistently hypermethylated in invasive cervical cancers and can potentially be used as a clinical marker of cancer progression.Moreover,promoters of tumor suppressor genes (TSGs) involved in many cellular pathways are methylated in cervical precursors and invasive cancers.Some are associated with squamous cell carcinomas,and others are associated with adenocarcinomas.Identification of methylated TSGs in Pap smear could be an adjuvant test in cervical cancer screening for triage of women with high-risk HPV,atypical squamous cells of undetermined significance,or low grade squamous intraepithelial lesion (LSIL).However,consistent panels must be validated for this approach to be translated to the clinic.Furthermore,reversion of methylated TSGs using demethylating drugs may be an alternative anticancer treatment,but demethylating drugs without toxic carcinogenic and mutagenic properties must be identified and validated.

    The new German S3 guideline 'Prevention of Cervical Cancer' published in 2016 is based on the latest available evidence about cervical cancer screening and treatment of cervical precancer. Large randomized controlled trials indicate that human papillomavirus (HPV)-based screening may provide better protection against cervical cancer than cytology alone through improved detection of premalignant disease in the first screening round prior to progression. Therefore, women aged 30 years and older should preferably be screened with HPV testing every 3-5 years (cytology alone every 2 years is an acceptable alternative). Co-testing is not recommended. Screening should start at 25 years using cytology alone every 2 years. The preferred triage test after a positive HPV screening test is cytology. Women positive for HPV 16 and HPV 18 should receive immediate colposcopy. Another alternative triage method is p16/Ki-67 dual stain cytology. The mean yearly participation rate in Germany is between 45 and 50%. Offering devices for HPV self-sampling has the potential to increase participation rates in those women who are at higher risk of developing cervical cancer. Regarding primary prevention, the 9-valent vaccine may provide protection against up to 85% of cervical intraepithelial neoplasia (CIN) 3 and 90% of cervical cancer, and is available in Europe as a 2-dose schedule from May 2016.

  11. Cervical neurofibromas in children with NF-1

    International Nuclear Information System (INIS)

    Background. Children with neurofibromatosis type 1 (NF1) are at increased risk of developing plexiform neurofibroma throughout the body, including the cervical soft tissues. However, the incidence of cervical soft tissue tumors and the value of screening MR for children with NF1 are not known. Purpose. The purposes of this study were to determine the incidence and clinical significance of cervical tumors seen on MR imaging in children with NF1. Materials and methods. A retrospective review of the brain and orbit MR with cervical images obtained on 95 children who meet the NIH consensus criteria for NF1 and who are followed at our neurofibromatosis clinic was carried out. Results. Cervical tumors were found on MR imaging in 21 of 95 (22 %) children. Of 21 children with cervical tumors, 14 children were determined to be surgical candidates. In nine children, MR imaging altered the clinical management by demonstrating tumors for which surgery was indicated, but the tumors were not suspected prior to MR imaging. Conclusion. Cervical tumors are commonly seen in children with NF1. MR imaging may demonstrate a significant number of tumors that require surgery, but were not suspected prior to MR imaging. (orig.)

    Cervical vertigo refers to a syndrome with a chief complaint of vertigo arising from cervical verteprae discomfort. In general, cervical vertigo is correlated with but not always caused by cervical spondylopathy,which mainly includes vertebral arterial and sympathetic cervical spondylosis. The vertebral artery insufficiency caused by compression from lateral displacement of the intervertebral dise is very rare, while the sympathetic cervical spondylosis caused by the vertebral instability is much more common. Rigorous criteria have been developed for diagnosis of the latter. Conservative therapy is mainly recommended for treatment of cervical vertigo.%颈性眩晕通常与颈椎病有关,但不一定完全由颈椎病所致.与颈性眩晕有关的主要是椎动脉型和交感型颈椎病.由椎间盘侧突压迫导致的椎动脉供血不足非常罕见,由椎体不稳引起的交感型颈椎病较多,但后者也有其严格的诊断标准.治疗以保守治疗为主.

    detección oportuna de cáncer basados en citología, particularmente en países con altos y medianos ingresos. Sin embargo, en muchos países de bajos ingresos el programa de detección oportuna de cáncer basado en citología apenas está siendo implantado correctamente o tiene fallas, por lo que no se puede apreciar el alcance para reducir las tasas de este cáncer. El hecho es que la infección con ciertos tipos de virus de papiloma humano es ahora reconocida como una causa necesaria de la enfermedad, lo que ha conducido a nuevas investigaciones frente a la prevención del cáncer cervical. Las pruebas de ADN del virus del papiloma humano se han mostrado como una herramienta prometedora con gran sensibilidad, pero con especificidad más baja que la citología. En combinación con citología ginecológica, la prueba del virus del papiloma humano tiene potencial para mejorar el valor predictivo negativo de la prueba convencional, permitiendo incrementar los intervalos de periodicidad de la misma y poder disminuir los costos del programa con seguridad aceptable. Los avances en el procesamiento de la prueba de citología y automatización de pruebas que determinan ADN del virus, han permitido nuevas propuestas de tamizaje lo que incrementa cada vez más su aceptación en países de altos y medianos ingresos. Para países de bajos ingresos, se ha probado que la inspección visual con ácido acético es una alternativa efectiva para la citología convencional, especialmente observada en sitios en los que los programas de tamizaje no han sido organizados. Referente a la prevención primaria del cáncer cervical, investigaciones recientes sobre seguridad y eficacia de la vacuna profiláctica contra el virus del papiloma humano han mostrado resultados muy prometedores con una eficacia cercana a 100% en prevención de infecciones persistentes y desarrollo de lesiones precursoras de este cáncer. Sin embargo, las políticas generadas son fuertemente cautelosas para evitar

    Full Text Available Introduction. Spontaneous dissection of the cervical artery is a rare non-atherosclerotic vascular disease of unknown aetiology and unclear pathogenesis that may be a cause of ischemic stroke in young adults. Diagnosis. Precise diagnosis of dissection of the cervical artery - carotid or vertebral - is possible with cervical axial magnetic resonance imaging and magnetic resonance angiography. Treatment. The recommended treatment in the acute phase of cervical artery dissection is anticoagulant or antithrombotic therapy, aimed at preventing a primary or recurrent ischemic event. There have been as yet no results of randomized controlled studies comparing efficacy of both treatments. An ongoing randomized multicentre study is expected to provide answers about the effects of these treatments in cervical artery dissection. Outcome. Complete resolution of arterial abnormalities is achieved in around 46% of stenoses, 33% of occlusions, and 12% of dissecting aneurysms. Recurrent events. Recurrence of cerebral ischemia and cervical artery dissection seems to be rare, although some data suggest that early ischemic and late cervical artery dissection recurrences could be underestimated. Mortality and functional outcome. In comparison with other causes of stroke in young adults, the functional outcome of cervical artery dissection is good in contrast to its socio-professional effects, which may be unsatisfactory. The mortality rate of cervical artery dissection is low, although it may be underestimated since some patients with malignant infarction die before the diagnosis is established. Conclusion. Further research is warranted to improve our understanding of the underlying pathophysiology, to assess the long-term outcome, and ultimately to provide treatment and prevention strategies.

  17. Radiological evaluation of the cervical spinal trauma

    International Nuclear Information System (INIS)

    Acute injuries of the cervical spine are the most common causes of severe disability following trauma, yet the diagnosis of these injuries are often delayed and the treatment, inadequate. Traumatic injuries of the cervical spine are diagnosed by radiological examinations. And complete evaluations of bony structures and soft tissue changes on conventional radiograms are very important for determining the therapeutic plans and prognoses of the injuries patients. During the period of 5 years from June 1976 to May 1981, the radiological and clinical evaluation had been made on 38 patients suffered from acute cervical spinal injuries which were confirmed by the radiological examinations. The results were as follows. 1. Age distribution of total 38 patients was broad ranging from 19 years to 72 years. 2. The most common cause of injury was traffic accident, next fall down, other accident respectively. 3. Levels of the cervical spinal injuries were as follows: Upper cervical spine in 15.8%, lower cervical spine in 84.2%, and the most common injuries level was C 5. Most of the lower cervical spinal injuries were located in the vertebral body and spinous process. 4. Anatomical sites of the cervical spinal injuries were as follows; vertebral body in 55.5%, spinous process in 23.7%, neural arch in 15.8%, and locked facet in 18.4%, etc. 5. Most of the patients with severe mental changes were injuries in upper cervical spine rather than lower.

However, an estimation of cost burden of abnormal smears, cervical pre-invasive and invasive diseases needs to be done to show how much spending has been allocated to the problem. An expert panel committee came up with the clinical pathway and management algorithm of  cervical pre invasive and invasive diseases from July-December 2006 Malaysia. An activity based costing for each clinical pathway was done. Results were converted to USD. The cost of managing pre-invasive cervical cancers stage is USD 420,150 (Range: USD 197,158-879,679. Management of invasive cancer (new cases costs USD 51,533,233.44 (Range: USD 32,405,399.69 - USD 129,014,768.40. The cost of managing existing cases is USD 17,005,966.87 (Range: USD 10,693,781.90 - USD  28,901,587.12. The total cost of managing cervical cancers by health care providers in a public setting is around USD 75,888,329.45 (Range: USD 48,083,804.60 - USD 48,083,804.60. The outcome of this study has shown that preventive modalities such as screening have only contributed to 10.3 % of the total management cost of cervical cancer. The major cost contribution (67% came from treatment of invasive cancer especially at more advanced stages of cancer, followed by treatment of existing cases (22% and lastly on pre-invasive disease (0.6%. This study revealed that proportion of preventive modality in this country was still low, and the major cost came from actual treatment cost of cervical cancer. Therefore, heightened public cervical cancer screening in the country is needed. (Med J Indones 2008; 17: 272-80Keywords: cervical cancers, pre invasive disease, HPV vaccination

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.

    The main methods of treatment for cervical cancer are surgery, radiotherapy or their combination. During past two decades chemotherapy are increasingly being used not only in patients with disseminated forms of this disease but also in patients undergoing chemoradiotherapy or as induction therapy. Possibilities of adjuvant chemotherapy for cervical cancer are being studied. According to A.D.Kaprin and V.V. Starinskiy in 2013 in Russia, 32% of patients with newly diagnosed cervical cancer underwent only radiation therapy, 32%--combined or complex treatment, 27.3%--only surgery, and just 8.7%--chemoradiotherapy.

  9. Cervical spine fractures and dislocations in children

    International Nuclear Information System (INIS)

    A retrospectivce analysis of pediatric admissions over 10 years revealed 29 patients with cervical spine injuries. Eleven patients were below 12 years of age, and 10 of these had injuries involving C1, C2 or the occipitoatlantal articulation. Eighteen patients were between 12 and 16 years of age with injuries distributed throughout the cervical spine similar to injuries in the adult population. Our results suggest that teenagers with suspected cervical injuries are best evaluated by an adult radiographic series including trauma oblique views. In younger patients, careful evaluation of occipitoatlantoaxial alignment and the prevertebral soft tissues is required for diagnosis and selection of additional imaging evaluation. (orig.)

    Actinomyces naeslundii, an oral biofilm bacterium of, can be cured using intravenous piperacillin, clindamycin, and surgery. We report a case of cervical actinomycosis due to Actinomyces naeslundii. A 56-year-old man seen for right cervical swelling had undergone dental work. Computed tomography indicated an abscess, from which we aspirated pus using a needle. Although no sulfur granules were found, pus yielded Actinomyces naeslundii. This case is, to our knowledge, the first reported in Japan of cervical actinomycosis due to A. naeslundii. PMID:21838058

    Full Text Available To evaluate the cervical spine rotation movement is quiet harder than other joints. Configuration and arrangement of current goniometers and devices is not always practic in clinics and some methods are quiet expensive. The cervical axial rotation goniometer designed by the authors is consists of five pieces (head apparatus, chair, goniometric platform, eye pads and camera. With this goniometer design a detailed evaluation of cervical spine range of motion can be obtained. Besides, measurement of "joint position sense" which is recently has rising interest in researches can be made practically with this goniometer.

  12. Expression of Tissue factor in Adenocarcinoma and Squamous Cell Carcinoma of the Uterine Cervix: Implications for immunotherapy with hI-con1, a factor VII-IgGFc chimeric protein targeting tissue factor

    International Nuclear Information System (INIS)

    Cervical cancer continues to be an important worldwide health problem for women. Up to 35% of patients who are diagnosed with and appropriately treated for cervical cancer will recur and treatment results are poor for recurrent disease. Given these sobering statistics, development of novel therapies for cervical cancer remains a high priority. We evaluated the expression of Tissue Factor (TF) in cervical cancer and the potential of hI-con1, an antibody-like-molecule targeted against TF, as a novel form of immunotherapy against multiple primary cervical carcinoma cell lines with squamous- and adenocarcinoma histology. Because TF is a transmembrane receptor for coagulation factor VII/VIIa (fVII), in this study we evaluated the in vitro expression of TF in cervical carcinoma cell lines by immunohistochemistry (IHC), real time-PCR (qRT-PCR) and flow cytometry. Sensitivity to hI-con1-dependent cell-mediated-cytotoxicity (IDCC) was evaluated in 5-hrs-51chromium-release-assays against cervical cancer cell lines in vitro. Cytoplasmic and/or membrane TF expression was observed in 8 out of 8 (100%) of the tumor tissues tested by IHC and in 100% (11 out of 11) of the cervical carcinoma cell lines tested by real-time-PCR and flow cytometry but not in normal cervical keratinocytes (p = 0.0023 qRT-PCR; p = 0.0042 flow cytometry). All primary cervical cancer cell lines tested overexpressing TF, regardless of their histology, were highly sensitive to IDCC (mean killing ± SD, 56.2% ± 15.9%, range, 32.4%-76.9%, p < 0.001), while negligible cytotoxicity was seen in the absence of hI-con1 or in the presence of rituximab-control-antibody. Low doses of interleukin-2 further increased the cytotoxic effect induced by hI-con1 (p = 0.025) while human serum did not significantly decrease IDCC against cervical cancer cell lines (p = 0.597). TF is highly expressed in squamous and adenocarcinoma of the uterine cervix. hI-con1 induces strong cytotoxicity against primary cervical cancer cell

    2004-05-01

    We present the case of a 44-year-old man who complained of cervical pain. He was treated with physiotherapy and analgetics. Because of persistent pain, computed tomography (CT) scan and MRI were performed. They revealed an osteolytic destruction of the fourth cervical vertebra. The patient was treated surgically for removal of the tumor and stabilization of his cervical spine. Histology of the osteolytic material led to the diagnosis of an eosinophilic granuloma of the cervical spine. This case report describes the incidence, clinical significance, background and therapy of an eosinophilic granuloma of the spine. PMID:15120180

  15. Distracted cervical spinal fusion for management of caudal cervical spondylomyelopathy in large-breed dogs

    International Nuclear Information System (INIS)

    Using an autogenous bone graft (obtained from the iliac crest), 4-mm cancellous bone screws, and polymethylmethacrylate, a distracted cervical spinal fusion technique was performed on 10 dogs with myelographic evidence of caudal cervical spondylomyelopathy. All dogs had evidence of dynamic soft tissue spinal cord compression, as indicated by flexion, extension, and traction myelographic views. Of the 10 dogs, 4 previously had undergone surgery by use of ventral slot or cervical disk fenestration techniques, and their neurologic status had deteriorated after the original surgery. Preoperative neurologic status of the 10 dogs included nonambulatory tetraparesis (n = 5), severe ataxia with conscious proprioceptive deficits (n = 2), and mild ambulatory ataxia with conscious proprioceptive deficits (n = 3). Five dogs had signs of various degrees of cervical pain. Clinical improvement was observed in 8 of 10 dogs--either improved neurologic status or elimination of cervical pain. Implant loosening developed in 3 dogs; 2 of them were euthanatized because of lack of neurologic improvement. Radiographic evidence of bony cervical fusion was observed during a 9- to 24-week period in 6 of the 8 surviving dogs. The distracted cervical fusion technique appears to be a valid surgical procedure to manage cervical spondylomyelopathy in those dogs in which the lesions are limited to one cervical intervertebral disk space

    Full Text Available OBJETIVO: Avaliar as razões para descontinuar diversos anticoncepcionais orais combinados entre mulheres brasileiras iniciantes do método, residentes em áreas urbanas. MÉTODOS: Estudo de corte transversal com 400 ginecologistas do Brasil, registrados na Federação Brasileira de Ginecologia e Obstetrícia. Cada médico entrevistou 10 mulheres não grávidas, não lactantes, não em amenorreia, com idades entre 18 e 39 anos que consultavam solicitando anticoncepcional oral combinado (ACO, com um questionário no início de uso e aos 6 meses posteriores. O questionário incluiu dados sociodemográficos, tipo de ACO escolhido ou prescrito e razões para descontinuação, caso ocorresse durante o seguimento. A estratégia de seleção permitiu a inclusão de mulheres de diferentes estratos socioeconômicos, mas somente atendidas em consultórios privados ou de convênios. O tamanho da amostra foi estimado em 1.427 mulheres. RESULTADOS: Foram obtidas 3.465 entrevistas na primeira visita e 1.699 aos 6 meses posteriores. As mulheres tinham predominantemente entre 20 e 29 anos, 57,3% eram solteiras e em proporção quase igual de 45% tinham ensino médio ou superior. A maioria (60,7% era nuligestas e dentre as que tinham usado algum método contraceptivo anteriormente, 71,8% tinham utilizado ACO. Entre os ACO mais prescritos ou escolhidos, o mais prevalente foram os monofásicos com etinilestradiol (20 µg e no tocante ao progestágeno, o mais prevalente foi com gestodeno (36,5%, seguido por ACO com drosperinona (22,0%. Aos 6 meses, 63,5% continuavam em uso do ACO. Dentre as que descontinuaram o uso, as principais razões dadas foram: desejo de engravidar (36,5% e efeitos colaterais (57,3% como cefaléia (37,6%, aumento de peso (16,6% e sangramento irregular (23,6%. CONCLUSÕES: A taxa de continuação do uso de ACO foi baixa aos seis meses e este estudo pode contribuir para que os médicos orientem melhor suas pacientes iniciantes no uso de ACO

    Science.gov (United States)

    Koenig, Rainer; Bergander, S.

    1990-11-01

    In the context of the early recognition of cervical cancer the cytology has to detect tumor positive cases among a bulk of un suspicious specimens. Unfortunately there is a group of cases with a vague diaxosis, the so called PAP-ill-group. There are many reasons for the recent impossibility of a safe conclusion from the PAP-Ill-smears to their histological diagnoses (Pig. 1). Today for an exact statement a cone biopsy and a microscopical investigation of its histological sections for such caseS are necessary. That results in a high medical and economical expense and, last not least, that means a higher risk of complications and of future family planning problems for the women affected.

  3. Imaging advances in upper cervical vertebral disease

    International Nuclear Information System (INIS)

    Upper cervical vertebral has complex anatomic structure and some diseases may involve this vital center area of human body. Most of the diseases, such as trauma, malformation, and degeneration, need to be treated with surgery to recover the function of cervical vertebral. The accurate evaluation is crucial before and after the surgery. In the past few years, CT, MRI, and ultra-sound play important roles in the evaluation of upper cervical vertebral diseases and planning treatment. Comprehensive evaluation with multidisciplinary approach is advocated. In this paper we reviewed the anatomy and clinic treatments; summarized the latest imaging advances in upper cervical vertebral disease; discussed the perspective of comprehensive evaluation with multidisciplinary approach.

    Five horses, weighing 337 to 400 kg, were used in this research, one of them being used as control. Cervical myelography with iohexol (Omnipaque) was performed on four horses tranquilized with flunitrazepan before induction of anesthesia with sodium thiopental. Anesthesia was maintained with fluothane and oxygen. Cerebrospinal fluid (CSF) was analysed before and after an injection of ioxheol into the subarachnoid space. The animals received 25 to 50 ml of iohexol, after removal of 20 ml cerebrospinal fluid. Radiographies were taken with the horses at lateral recumbency, and the cranial, central and caudal regions of the cervical spine being focalized. No significant changes occurred in the cerebrospinal fluid after injecting the contrast medium. Pathologic changes were not found by gross or microscopic examination of the brain and the cervical spinal cord. Radiographies of good to excellent image quality were obtained. At autopsy, radiographic diagnosis of cervical vertebral instability was confirmed in the animal that had pelvic limb ataxia

  8. Radiosensitizers in cervical cancer. Cisplatin and beyond

    International Nuclear Information System (INIS)

    Cervical cancer continues to be a significant health burden worldwide. Globally, the majority of cancers are locally advanced at diagnosis; hence, radiation remains the most frequently used therapeutical modality. Currently, the value of adding cisplatin or cisplatin-based chemotherapy to radiation for treatment of locally advanced cervical cancer is strongly supported by randomized studies and meta-analyses. Nevertheless, despite these significant achievements, therapeutic results are far from optimal; thus, novel therapies need to be assayed. A strategy currently being investigated is the use of newer radiosensitizers alone or in combination with platinum compounds. In the present work, we present preclinical information on known and newer cytotoxic agents as radiosensitizers on cervical cancer models, as well as the clinical information emanating from early phase trials that incorporate them to the cervical cancer management. In addition, we present the perspectives on the combined approach of radiation therapy and molecular target-based drugs with proven radiosensitizing capacity

    An unusual case of myositis ossificans traumatica lesion located in the paraspinal region is reported. Despite the contiguity of the lesion with the cervical vertebrae and ominous appearance of the biopsy material, the history of antecedent trauma and computed tomography findings allowed preoperative accurate diagnosis. To our knowledge, myositis ossificans traumatica located in the cervical paraspinal region is very rare. (orig.) With 4 figs., 16 refs.

    Full Text Available Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO′M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI and the Centre for Epidemiologic Studies Depression questionnaire (CES-D. Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64. Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision.

    Full Text Available Abstract Background Worldwide cervical cancer remains a leading cause of mortality from gynecologic malignancies. The link between cervical cancer and persistent infection with HPV has been established. At a molecular level little is known about the transition from the precancerous state to invasive cancer. To elucidate this process, cervical biopsies from human specimens were obtained from precancerous state to stage III disease. Methods Cervical biopsies were obtained from patients with a diagnosis of cervical cancer undergoing definitive surgery or staging operation. Biopsies were obtained from patients with precancerous lesions at the time of their excisional procedure. Control samples were obtained from patients undergoing hysterectomy for benign conditions such as fibroids. Samples were subjected to proteomic profiling using two dimensional gel electrophoresis with subsequent trypsin digestion followed by MALDI-TOF protein identification. Candidate proteins were then further studied using western blotting, immunoprecipitation and immunohistochemistry. Results Annexin A1 and DNA-PKcs were found to be differentially expressed. Phosphorylated annexin A1 was up regulated in diseased states in comparison to control and its level was strongly detected in the serum of cervical cancer patients compared to controls. DNA-PKcs was noted to be hyperphosphorylated and fragmented in cancer when compared to controls. By immunohistochemistry annexin A1 was noted in the vascular environment in cancer and certain precancerous samples. Conclusion This study suggests a probable role for protein tyrosine phosphorylation in cervical carcinogenesis. Annexin A1 and DNA-PK cs may have synergistic effects with HPV infection. Precancerous lesions that may progress to cervical cancer may be differentiated from lesions that will not base on similar immunohistochemical profile to invasive squamous cell carcinoma.

    Cervical cancer is the second most common cause of cancer death in women worldwide and the development of new diagnosis, prognostic, and treatment strategies merits special attention. Although surgery and chemoradiotherapy can cure 80%-95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

    Anterior cervical hypertrichosis is a very rare form of primary localized hypertrichosis. It consists of a tuft of terminal hair on the anterior neck just above the laryngeal prominence. The etiology is still unknown. In this article, we reported a 15-year-old female patient who presented to our clinic with a complaint of hypertrichosis on the anterior aspect of the neck for the last five years. Her past medical history revealed no pathology except for vesicoureteral reflux. On the basis of clinical presentation, our patient was diagnosed with anterior cervical hypertrichosis and she was considered to be a sporadic case due to lack of other similar cases in familial history. To date, 33 patients with anterior cervical hypertrichosis have been reported. Anterior cervical hypertrichosis can be associated with other abnormalities, but it frequently presents as an isolated defect (70%). The association of vesicoureteral reflux and anterior cervical hypertrichosis which was observed in our patient might be coincidental. So far, no case of anterior cervical hypertrichosis associated with vesicoureteral reflux has been reported in the literature. PMID:27103865

    2012-01-01

    Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy.

    Background A considerable number of patients with cervical spondylosis complain about one or multiple atypical symptoms such as vertigo, palpitations, headache, blurred vision, hypomnesia, and/or nausea. It remains unclear whether surgical intervention for cervical spondylosis can also effectively alleviate those symptoms. The current study was performed to see if anterior cervical diskectomy and fusion (ACDF) offers such an extra benefit for patients with cervical spondylosis. Objective To investigate if patients who received ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy can also achieve alleviation of certain atypical symptoms associated with cervical spondylosis after the surgery in the long run. Methods Sixty-seven patients who underwent ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy were involved in this study. All these patients also complained about various associated atypical symptoms. They were followed up for 26 to 145 months after the surgery. Severity and frequency scores of the atypical symptoms before the surgery and at last follow-up were compared by paired t tests. Results Most patients reported significantly alleviated symptoms at the last follow-up compared with before the surgery. The severity of vertigo, headache, nausea, and palpitations were significantly alleviated at the last follow-up (with p values of p cervical spondylotic myelopathy and/or radiculopathy, but it is not effective in alleviating symptoms such as tinnitus, blurred vision, and hypomnesia. It can be considered for alleviating atypical symptoms when other treatment options prove ineffective. PMID:27168319

    Full Text Available Worldwide, cervical cancer is the third most common cancer in women, and the first or second most common in developing countries. Cervical cancer remains in Colombia the first cause of cancer mortality and the second cause of cancer incidence among women, despite the existence of screening programs during the last 3 decades. Bucaramanga, Manizales and Cali reported rates around 20 per 100,000 and Pasto 27 per 100,000. The Cali cancer registry has reported a progressive decrease in the age standardized incidence and mortality rates of cervical cancer over the past 40 years. Reasons for the decline in incidence and mortality of cervical cancer are multiple and probably include: improvement in socio-economic conditions, decrease in parity rates and some effect of screening programs.Human papilloma Virus is the main cause of cervical cancer, HPV natural history studies have now revealed that HPVs are the commonest of the sexually transmitted infec¬tions in most populations. Most HPV exposures result in sponta¬neous clearance without clinical manifestations and only a small fraction of the infected persons, known as chronic or persistent carriers, will retain the virus and progress to precancerous and cancer. HPV 16 and 18 account for 70% of cervical cancer and the 8 most common types. (HPV 16, 18, 45, 33, 31, 52, 58 and 35 account for about 90% of cervical cancer. Case-control studies also allowed the identification of the following cofactors that acting together with HPV increase the risk of progression from HPV persistent infection to cervical cancer: tobacco, high parity, long term use of oral contraceptives and past infections with herpes simplex type 2 and Chlamydia trachomatis. The demonstration that infection with certain types of human papillomavirus (HPV is not only the main cause but also a necessary cause of cervical cancer has led to great advances in the prevention of this disease on two fronts: (i Primary prevention by the use of

The objective of this work is to determine the effect of the incorporation from the BrdU to the DNA on the genotoxicity and cytotoxicity of the cells of the bone marrow caused by the radiopharmaceutical {sup 153}Sm-EDTMP. The genotoxicity was determined by the rate of erythrocytes polychromatic micro nucleates (EPC-MN) and the cytotoxicity by the frequency of EPC. Both parameters determined in peripheral blood after the BrdU administration and {sup 153}Sm-EDTMP.

    We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance ({rho} > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury.

  13. Letter: Contraceptive choice and cervical cytology.

    1974-02-15

    In the evaluation of biological potentials of contraceptives in the genesis of cervical cancer, cytology seems to have been given due attention while information on the clinical condition and specific treatment of the target organ, the cervix, is repeatedly neglected. "Cancer does not develop in a healthy cervix" is an old dogma derived from impressions gained by clinical examination of the organ. This concept is supported by epidemiologic studies indicating that cancer is extremely rare in cervices restored to a normal condition by cauterization. It may be postulated that this type of treatment destroys the permissive target cells of the cervix, thus indirectly rendering possible coitus-associated and contraceptive-associated(?) mutagen(s) invalid. Also, in comparative studies, an evaluation should be made of the significance of a higher incidence of cervical ectopy reported in women receiving oral hormonal contraceptives. The importance of ectopy in the genesis of cervical malignancy has been derived from the presumption that permissive cervical cells are thus created and exposed to vaginal contents which may harbor the mutagens(s). Therefore, it would seem not only desirable but imperative to include the neglected parameters of clinical condition and of specific treatment (both past and present) of the uterine cervix in the structure of studies like the recent one in this Journal on "Contraceptive choice and cervical cytology", by Drs. Shulman and Merritt. Still another parameter which might prove to be of significance is the predominant type of vaginal flora, which can be assessed readily in the routine examination of Papanicolaou smears. It may be that vaginal contents, which would seem to be somewhat different in wearers of the intrauterine contraceptive device as compared to "pill" users, might play a part in the advent of cervical malignancy as a medium of or for coitus-associated mutagens(s).

Although surgery and chemoradiotherapy can cure 80%–95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.Keywords: Cervical cancer, clinical trials, gene therapy, HPV E6 and E7 oncogenes, siRNAs

    Full Text Available Abstract Background The female lower genital tract is a gateway for pathogens entering the host through the mucous membrane. One of the prevalent human viruses is Torque teno virus (TTV. The major reported routes of TTV transmission are fecal-oral and parenteral. Furthermore, other modes of transmission, e.g. sexual contact, are suggested. To investigate the sexual route of TTV transmission, cervical smears of healthy women and those with cervical lesions were screened for the presence of TTV DNA. Methods TTV DNA was studied in cervical smears of 95 patients with cervical lesions and 55 healthy women. Paired serum samples were available from 55 and 42 women, respectively. All healthy women had normal cytology while 44 patients had histologically confirmed low-grade lesion (LGL and 51 high-grade lesion (HGL. TTV DNA was detected with primers specific for the non-coding region. In 40 paired cervical smears and serum samples, the phylogenetic group of TTV isolates was determined. The presence of HPV DNA in cervical smears was detected by means of PCR with MY09/11 primers. Results The prevalence of TTV DNA in cervical smears of healthy women was 52.7% and was comparable with that in paired serum samples (50%. Symptomatic women had significantly higher prevalence of TTV DNA in cervical smears (74.7% than healthy controls. The TTV DNA prevalence in patient serum samples was 51%. The phylogenetic groups of TTV serum isolates were concordant with those of TTV from cervical smears of the same subjects. In cervical smears, a wider variety of TTV isolates was found. The viral loads in cervical smears were 10 to 1000 times as high as in sera. The HPV-positive study subjects had significantly higher TTV DNA prevalence than HPV negatives. The prevalence of TTV was not associated with disease severity. Conclusion High prevalence of TTV in cervical smears suggests that sexual transmission is another mode of expansion of TTV infection among the population. The

    The case of a one-month-old patient admitted to the Department of Pediatrics (Medical and Health Science Center, Debrecen University) because of respiratory distress caused by a cervical mass compressing the upper respiratory pathways is presented. The mass could only be partially removed, the histological diagnosis proved to be neuroblastoma (SBCT: "small blue cell tumor"). Despite the fact that the DNA index of tumor cells (ploidy measurements) and the age of the patient suggested a favourable prognosis, the tumor continued to grow and metastases appeared. Because of symptoms of compression exerted on the respiratory system by the tumor, chemotherapy had to be applied. Since a standard OPEC/OJEC chemotherapeutic protocol proved to be not entirely effective and a residual tumor was still present, retinoic acid and interferon treatment was introduced. Presently, 4 years after the diagnosis, the patient is in complete remission and can be considered to be cured. The case presented here demonstrates that despite the favorable prognosis of the majority of infant neuroblastomas, in some cases the anatomic location of the tumor, leading to disturbance of vital functions, may serve as indication of chemotherapy. Our experience also proved the efficacy of retinoic acid and interferon treatment in relapsed neuroblastoma. PMID:15105902

    Several different physics procedures have been tried to mechanize the recording of partograms. Can a measure of impedance of tissue Z using potential difference V, according to Ohm's law V = Z1, and 1 is a constant, be correlated with a measure of cervical dilatation using vaginal examination? This was our hypothesis. The tissue impedance meter was made to our design and applied according to a bipolar procedure. Our work was carried out on 28 patients. 10 patients were registered before labour started in order to test the apparatus and to record the impedance variations without labour taking place, and 18 patients were registered in labour to see whether there was any correlation. The level of impedance in the cervix without labour was 302.7 Ohms with a deviation of 8.2. Using student's t tests it was found that there was a significant correlation (p less than 0.001) in four measurements between the impedance measure and measures obtained by extrapolating the degrees of dilatation calculated from vaginal examination. This is a preliminary study in which we have defined the conditions that are necessary to confirm these first results and to further develop the method. PMID:1401774

    In this work a technical and economical analysis of the installation of a reverse osmosis desalting plant connected to a power station that uses the combined cycle technology under a co-generation scheme is presented: production of electricity and water. The operation program of the desalting power station will be determined by the demand of energy of the combined cycle power station; the proposal is that the desalting plant operates in the hours of low load of the power station and shuts down at the peak hours of electrical energy demand. So that this study is representative, the demand curves of electric energy of the units of combined cycle of Central President Juarez Rosarito of the Comision Federal de Electricidad (CFE) have been taken and updated the data of the reverse osmosis desalting plants that are available at the moment in the market. As basis of the study the level costs will be determined so much as the electrical energy generated by the power station of combined cycle, operating inside and outside of a co-generation scheme and the costs made level for the water produced by the reverse osmosis plant under two assumptions: the first one is buying the electrical energy from CFE and the second one considering that the CFE is the owner of the desalting plant and therefore the cost of electrical energy to desalting the plant is zero. This work shows the economic impacts on the costs of the generation of electrical energy and on those of the desalted water in a co-generation scheme. The results shown in this study can be considered for the future planning in the construction of desalting plants to supply of water in the Northwestern zones of the country where serious problems of water shortage exist.

    Full Text Available Experimental, clinical, and epidemiological evidence strongly suggests that genital Human Papillomaviruses (HPVs are predominantly sexually transmitted. Epidemiological studies in virginal and HPV-negative women clearly indicate that sexual intercourse is virtually a necessary step for acquiring HPV. As with any other sexually transmitted disease (STD men are implicated in the epidemiological chain of the infection. Penile HPVs are predominantly acquired through sexual contacts. Sexual contacts with women who are prostitutes play an important role in HPV transmission and in some populations sex workers may become an important reservoir of high-risk HPVs. Acting both as "carriers" and "vectors" of oncogenic HPVs male partners may markedly contribute to the risk of developing cervical cancer in their female partners. Thus, in the absence of screening programs, a woman's risk of cervical cancer may depend less on her own sexual behavior than on that of her husband or other male partners. Although more rarely than women, men may also become the "victims" of their own HPV infections as a fraction of infected men are at an increased risk of developing penile and anal cancers. Male circumcision status has been shown to reduce the risk not only of acquiring and transmitting genital HPVs but also of cervical cancer in their female partners. More research is needed to better understand the natural history and epidemiology of HPV infections in men.Evidencia experimental, clínica y epidemiológica demuestra que los papilomavirus humanos (VPH genitales son predominantemente de transmisión sexual. Estudios experimentales en mujeres vírgenes y en mujeres VPH-negativas indican de forma clara que el coito es virtualmente un paso necesario para adquirir el VPH.

  17. Invasive cervical carcinoma (Stages IB-IIB)

    International Nuclear Information System (INIS)

    In the patients with invasive cervical carcinoma, the accurate assessment of parametrial invasion greatly affects the therapeutic choice between surgery and radiation therapy. As a matter of fact, surgery is usually performed only in the patients with carcinoma confined to the cervix, whereas those with parametrial involvement, or more advanced stages, are treated with radiation therapy. This prospective study was aimed at investigating the comparative adequecy of CT and MR imaging in assessing parametrial status in the patients with invasive cervical cancer. Twenty-one consecutive patients, with histologic diagnosis of cervical carcinoma, were investigated. All of them were clinically considered as having invasive cervical cancer (FIGO stage IB-IIB) and subsequently underwent surgery. In all cases, detailed histology of the parametrium was obtained. Pathological data were compared with CT and MR findings in all cases. As for assessing parametrial involvement by cancer, CT had 62% accuracy, 63% sensitivity, and 60% specificity, versus MR imaging 81% accuracy, 69% sensitivity, and 80% specificify. Therefore, MR imaging appears to be superior to CT in assessing the parametrial status of patients with invasive cervical carcinoma; the method yields valuable information for treatment planning

    Full Text Available BACKGROUND AND OBJECTIVE: Cervical lymphadenopathy is the most common site of peripheral lymphadenopathy and is frequently encountered in otorhinolaryngology practice. Assessment and predicting its clinical behavior is not an easy task. Fine needle aspiration cytology (FNAC is being routin ely adopted as a special technique to diagnose the cause of lymphadenopathy. This study was undertaken to identify the clinic - demographic parameters in distribution of cases of cervical lymphadenopathy. FNAC was evaluated as a diagnostic tool by corroborat ing its results with histopathological examination of the excised lymph nodes. MATERIAL AND METHODS: This study was carried out at Hi - Tech Medical College and Hospital, Bhubaneswar, on 100 patients of cervical lymphadenopathy, over a period of two years. A long with detailed history, meticulous clinical examinations and investigations were performed. In all cases the diagnosis provided by FNAC and histopathology examination of the excised lymph node were correlated. RESULTS: Tuberculosis (45% was the most c ommon cause of cervical lymphadenopathy, followed by reactive (26% and metastatic secondaries (21% and lymphoma (8%. Maximum presentation was in 3 rd decade (22% and bilateral involvement was seen in 20% cases. Posterior triangle was the most common sit e involved (45%. Overall diagnostic accuracy of FNAC was 92%. CONCLUSION: Most common cause of cervical lymphadenopathy are tuberculosis, reactive lymphadenitis and metastatic secondaries. FNAC is a cheap, quick, readily available and dependable diagnostic modality and can be used as a first line investigatory tool in outdoor departments.

    Full Text Available Objective. We aim to investigate methods and use of cervical ripening in women without and with a prior cesarean delivery in The Netherlands. Methods. In 2010, we conducted a postal survey in all Dutch hospitals with a labor ward. One gynecologist per hospital was addressed and was asked to respond on behalf of the staff. The questionnaire contained 31 questions concerning cervical ripening and induction of labor. We compared this survey to a similar Dutch survey conducted in 2006. Results. Response rate was 78% (70/92 hospitals. In women without a prior cesarean and in need of cervical ripening, all hospitals (100% applied prostaglandins (either E1 or E2. In women with a prior cesarean, 21.4% of the hospitals performed an elective cesarean section if delivery was indicated (26.0% in 2006. In case of cervical ripening, 72.7% used mechanical methods (49.1% in 2006, 20.0% used prostaglandins (40.4% in 2006, 3.6% used a combination of prostaglandins and mechanical methods, and 3.6% used membrane-sweeping or oxytocin. Conclusions. In 2010, in The Netherlands, prostaglandins and Foley catheters were the preferred methods for cervical ripening in women without and with a prior cesarean, respectively. Use of mechanical methods in women with a prior cesarean has increased rapidly between 2006 and 2010, corresponding with decreasing use of prostaglandins and elective repeat cesarean sections.

    The objective of this prospective case-control study was to determine whether uterine corpus and cervical length measurements have a role in dysmenorrhoea aetiology in virgins. Patients with severe primary dysmenorrhoea with visual analog scale scores of ≥7 composed the dysmenorrhoea group (n = 51), while the control group (n = 51) was of women with painless menstrual cycles or with mild pain. Longitudinal and transverse axes of the uterine cervix and uterine corpus were measured. Correlation between severity of dysmenorrhoea and uterine cervix and corpus axes was calculated. Longitudinal and transverse axes of uterine cervix as well as uterine cervix volume were significantly higher in the dysmenorrhoea group compared to the controls. There was a significant positive correlation between severity of dysmenorrhoea and the length of cervical longitudinal and transverse axes and uterine cervical volume. Our findings reveal longer cervical length and greater cervical volume in young virgin patients with dysmenorrhoea and severe pain compared to those with no or less pain. PMID:27012227

Esse vírus de DNA infecta primariamente o epitélio e pode induzir lesões benignas ou malignas na pele e na mucosa. Alguns HPVs são considerados de alto risco, responsáveis pela progressão das lesões precursoras até câncer cervical. A infecção genital pelo HPV é comum em mulheres jovens e geralmente é transitória. Uma pequena proporção de mulheres infectadas desenvolve câncer cervical, implicando o envolvimento de fatores ambientais e fatores genéticos na carcinogênese. Essa revisão aborda a estrutura viral, classificação e patologia do HPV, história natural e fatores de risco para neoplasia cervical e perspectivas futuras com a vacina anti-HPV.Human papillomavirus (HPV has been established as an important etiological factor for the development of cervical cancer. This DNA virus primarily infects the epithelium and can induce benign and malignant lesions of the mucous membranes and skin. Some HPVs are considered high risk due to their role in malignant progression of cervical tumors. Genital HPV infections are common and usually transient among young sexually active women. Only a small fraction of infected women develop cervical cancer, implying the involvement of environmental and genetic cofactors in cervical carcinogenesis.

    Full Text Available 【Abstract】 Objectives: To explore the clinical fea- tures of traumatic atlantoaxial instability combined with subaxial cervical spinal cord injury (CSCI, and to analyze the feasibility, indication and therapeutic effects of ante- rior-posterior approach in such cases. Methods: From March 2004 to September 2009, 16 cases with this trauma were admitted and surgically treated in our department. Before surgery, skull traction was performed. Posterior atlantoaxial pedicle screw internal fixa- tion and bone graft fusion were conducted to manage trau- matic atlantoaxial instability . As for subaxial CSCI, anterior cervical corpectomy or discectomy decompression, bone grafting and internal fixation with steel plates were applied. Results: All operations were successful. The average operation time was 3 hours and operative blood loss 400 ml. Satisfactory reduction of both the upper and lower cervical spine and complete decompression were achieved. All pa- tients were followed up for 12 to 36 months. Their clinical symptoms were improved by various levels. The Japanese Orthopaedic Association (JOA scores ranged from 10 to 16 one year postoperatively, 13.95±2.06 on average (improvement rate=70.10%. X-rays, spiral CT and MRI con- firmed normal cervical alignments, complete decompression and fine implants’ position. There was no breakage or loos- ening of screws, nor exodus of titanium mesh or implanted bone blocks. The grafted bone achieved fusion 3-6 months postoperatively and no atlantoaxial instability was observed. Conclusions: Traumatic atlantoaxial instability may combine with subaxial CSCI, misdiagnosis of which should be especially alerted and avoided. For severe cases, one stage anterior-posterior approach to decompress the upper and lower cervical spine, together with reposition, bone grafting and fusion, as well as internal fixation can immedi- ately restore the normal alignments and stability of the cer- vical spine and effectively

    Epidural steroid injections (ESI) are a common treatment for back pain management. ESI-related complications have increased with the growing number of procedures. We report a case of cervical meningomyelitis followed by multiple lumbar ESI. A 60-year-old male with diabetes mellitus presented to our hospital with severe neck pain. He had a history of multiple lumbar injections from a local pain clinic. After admission, high fever and elevated inflammatory values were detected. L-spine magnetic resonance imaging (MRI) revealed hematoma in the S1 epidural space. Antibiotic treatment began under the diagnosis of a lumbar epidural abscess. Despite the treatment, he started to complain of weakness in both lower extremities. Three days later, the weakness progressed to both upper extremities. C-spine MRI revealed cervical leptomeningeal enhancement in the medulla oblongata and cervical spinal cord. Removal of the epidural abscess was performed, but there was no neurological improvement.

    Full Text Available Abstract Background Cervical cancer continues to be an important worldwide health problem for women. Up to 35% of patients who are diagnosed with and appropriately treated for cervical cancer will recur and treatment results are poor for recurrent disease. Given these sobering statistics, development of novel therapies for cervical cancer remains a high priority. We evaluated the expression of Tissue Factor (TF in cervical cancer and the potential of hI-con1, an antibody-like-molecule targeted against TF, as a novel form of immunotherapy against multiple primary cervical carcinoma cell lines with squamous- and adenocarcinoma histology. Methods Because TF is a transmembrane receptor for coagulation factor VII/VIIa (fVII, in this study we evaluated the in vitro expression of TF in cervical carcinoma cell lines by immunohistochemistry (IHC, real time-PCR (qRT-PCR and flow cytometry. Sensitivity to hI-con1-dependent cell-mediated-cytotoxicity (IDCC was evaluated in 5-hrs-51chromium-release-assays against cervical cancer cell lines in vitro. Results Cytoplasmic and/or membrane TF expression was observed in 8 out of 8 (100% of the tumor tissues tested by IHC and in 100% (11 out of 11 of the cervical carcinoma cell lines tested by real-time-PCR and flow cytometry but not in normal cervical keratinocytes (p = 0.0023 qRT-PCR; p = 0.0042 flow cytometry. All primary cervical cancer cell lines tested overexpressing TF, regardless of their histology, were highly sensitive to IDCC (mean killing ± SD, 56.2% ± 15.9%, range, 32.4%-76.9%, p p = 0.025 while human serum did not significantly decrease IDCC against cervical cancer cell lines (p = 0.597. Conclusions TF is highly expressed in squamous and adenocarcinoma of the uterine cervix. hI-con1 induces strong cytotoxicity against primary cervical cancer cell lines overexpressing TF and may represent a novel therapeutic agent for the treatment of cervical cancer refractory to standard treatment modalities.

Empirical antibiotic administration was given. Blood culture grew gram-positive cocci in chain, and there was no vegetation found by heart echocardiogram. However, progressive weakness of four limbs was noted, and patient even cannot stand up and walk. The patient also complained of numbness sensation over bilateral hands and legs, and lower abdomen. Acute urine retention occurred. We arranged magnetic resonance imaging survey, which showed evidence of inflammatory process involving the retropharyngeal spaces and epidural spaces from the skull base to the bony level of T5. Epidural inflammatory process resulted in compression of the spinal cord and bilateral neural foramen narrowing. Neurosurgeon was consulted. Operation with laminectomy and posterior fusion with bone graft and internal fixation was done. Culture of epidural abscess and 2 sets of blood culture all yielded methicillin-sensitive Staphylococcus aureus. For epidural abscess, the most common involved spine is lumbar followed by thoracic and cervical spine. Diagnosis and treatment in the drug abusers are still challenging because they lack typical presentation, drug compliance, and adequate follow-up and because it is hard to stop drug abuser habit. Significant improvement of neurological deficit can be expected in most spinal abscess in drug abusers after treatment. PMID:26298050

    Both tuberculosis cervical lymphadenitis (TCL) and oropharyngeal tularaemia (OT) have similar signs, symptoms and pathological findings. We aimed to investigate the frequency of tularaemia antibodies in patients diagnosed with TCL. Using data from the Tuberculosis Control Dispensaries between the years of 2008 and 2011 in Turkey, all patients diagnosed with TCL were informed about and included in the study. Control group subjects were selected from healthy blood donors who lived in the same region. After informed consent was obtained, the sera obtained from volunteer TCL patients and the control group were tested with a microagglutination technique for Francisella tularensis. Antibodies to Brucella were also investigated with a tube agglutination test for cross-reactivity in sera that were seropositive for tularaemia. Sera were obtained from a total of 1170 individuals in the TCL group and 596 in the control group from 67 of 81 provinces in Turkey. Francisella tularensis-positive antibodies were found in 79 (6.75%) cases in the TCL group and two (0.33%) cases in the control group with a titre of ≥1:80 (p < 0.01). When the presence of antibody of any titre was considered, the ratio became 8.2% (96/1170) in the TCL group and 0.67% (4/596) in the control group (p < 0.001). For the first time, with this study, tularaemia serology was found to be positive in a significant portion (6.75%) of diagnosed cases of TCL. In tularaemia endemic regions, it was concluded that tularaemia serology should be investigated in patients suspected of having TCL. PMID:23211027

  6. Radiological findings in cervical radicular avulsion

    International Nuclear Information System (INIS)

    Special aspects of examination techniques and positive myelographic findings in cervical radicular avulsion are reported. In addition, the possibilities and limits of myeloscintigraphy are discussed. Some observations and experiences with neuroradiological diagnosis of cervical radicular avulsion are reported which are of importance for the prognosis in brachial plexus injuries. It is determined that no direct relationship between myelographic-findings and nerve functions damage exists. The possibility of regeneration in serious traumatic injuries with extensive dural avulsion is demonstrated in two cases. Despite neuroradiological findings suggesting severe damage and the possibility of functional restitution is emphasized. (orig.)

    Full Text Available This is a case report of a patient with history of vague chest pain and facial numbness. When the patient was subjected for evaluation he was found to have cervical Schwannoma. He was operated and was successfully treated. Schwannomas are extramedullary-intradural tumors composed of Schwann cells, which can arise from spinal nerves at any level (cervical, thoracic, lumbar, or cauda equina and most often arise from a posterior (sensory nerve root. The most common initial symptom therefore is pain in a radicular distribution. Early detection and surgery gives excellent results in such cases.

    Nine patients with serious cervical spine injuries that occurred while they were playing rugby were seen in a British Columbia acute spinal cord injury unit during the period 1975-82. All the injuries had occurred during the "scrum" or the "tackle". Two of the patients were rendered permanently quadriplegic, and one patient died. There is a need for a central registry that would record all cervical spine injuries in rugby players as well as for changes in the rules of the game. PMID:6697282

    International Nuclear Information System (INIS)

    In this study the effectiveness of computed tomographic discography (CTD) in diagnosing cervical soft disc hernia was evaluated. Twenty-five interververtebral discs of 15 cases with cervical soft disc hernia were examined with a discography and then a CT scan. Results of the CT scan were as follows: three discs were protruded, 12 discs were prolapsed, 6 discs were extruded, and 4 discs were sequestrated. The findings were helpful in determining the location of soft disc hernians between the median and posterolateral discs. They were also valuable in classifying types of hernians and surgical aproaches. (author)

    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

  17. Cervical spine injury in child abuse: report of two cases

    International Nuclear Information System (INIS)

    Pediatric cervical spine injuries have rarely been reported in the setting of child abuse. We report two cases of unsuspected lower cervical spine fracture-dislocation in twin infant girls who had no physical examination findings to suggest cervical spine injury. Classic radio-graphic findings of child abuse were noted at multiple other sites in the axial and appendicular skeleton. Magnetic resonance (MR) imaging proved to be valuable in both the initial evaluation of the extent of cervical spine injury and in following postoperative changes. The unexpected yet devastating findings in these two cases further substantiate the importance of routine evaluation of the cervical spine in cases of suspected child abuse. (orig.)

    Full Text Available Thinking that one could not describe eugenics like a unique movement, since numerous bound varians took place related to the geographical and cultural context, this article tries to demostrate the peculiarity of the Italian case. 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. A «moderate» direction, Fascist, Catholic, that was built in consonance with the pronatalism of the regime and in rough polemic with the presumed Anglo-Saxon eugenics aberration.

    The aim of this study was to determine the frequency of abnormal cervical cytology in preoperative cervical cytology of patients diagnosed with uterine papillary serous carcinoma (UPSC) and endometrioid endometrial carcinoma (EEC). In addition, associations between abnormal cervical cytology and clinicopathologic factors were evaluated. In this multicentre study, EEC patients diagnosed at two hospitals from 1999 to 2009 and UPSC patients diagnosed at five hospitals from 1992 to 2009, were included. Revision of the histologic slides was performed systematically and independently by 3 gynecopathologists. Cervical cytology within six months before histopathologic diagnosis of endometrial carcinoma was available for 267 EEC and 80 UPSC patients. Cervical cytology with atypical, malignant, or normal endometrial cells in postmenopausal women was considered as abnormal cytology, specific for endometrial pathology. Abnormal cervical cytology was found in 87.5% of UPSC patients, compared with 37.8% in EEC patients. In UPSC, abnormal cytology was associated with extrauterine spread of disease (P=0.043). In EEC, abnormal cytology was associated with cervical involvement (P=0.034). In both EEC and UPSC patients, abnormal cervical cytology was not associated with survival. In conclusion, abnormal cervical cytology was more frequently found in UPSC patients. It was associated with extrauterine disease in UPSC patients, and with cervical involvement in EEC patients. More prospective research should be performed to assess the true clinical value of preoperative cervical cytology in endometrial cancer patients. PMID:23722512

En condiciones normales, el sistema inmune es capaz de controlar y eliminar la infección por acción de la inmunidad innata, la activación de una respuesta tipo celular y la creación de anticuerpos dirigidos principalmente a las proteínas de la cápside del virión (L1 y L2. A pesar de toda la maquinaria de protección inmune del hospedero, el virus posee estrategias de evasión, conservando un número reducido de copias en las células basales proliferantes y aprovechando la corta vida natural del queratinocito.

High-risk cervical human papillomavirus (HPV infection, permanence and replication are closely related to the development of cervical cancer. The immune system is able to control and clear such infection in normal conditions by innate immunity action, activating a cellular response and creating antibodies, mainly directed against virion capsid proteins (L1 and L2. In spite of the host’s entire immune protection machinery, the virus can take evasion strategies, maintaining a reduced number of copies in proliferating base cells and taking advantage of the keratinocyte’s short natural life. This review attempts to show the host’s different immunological mechanisms elicited in response to HPV infection.

    Full Text Available Abstract Background We estimated the number of women undergoing cervical cancer screening annually in Italy, the rates of cervical abnormalities detected, and the costs of screening and management of abnormalities. Methods The annual number of screened women was estimated from National Health Interview data. Data from the Italian Group for Cervical Cancer Screening were used to estimate the number of positive, negative and unsatisfactory Pap smears. The incidence of CIN (cervical intra-epithelial neoplasia was estimated from the Emilia Romagna Cancer Registry. Patterns of follow-up and treatment costs were estimated using a typical disease management approach based on national guidelines and data from the Italian Group for Cervical Cancer Screening. Treatment unit costs were obtained from Italian National Health Service and Hospital Information System of the Lazio Region. Results An estimated 6.4 million women aged 25–69 years undergo screening annually in Italy (1.2 million and 5.2 million through organized and opportunistic screening programs, respectively. Approximately 2.4% of tests have positive findings. There are approximately 21,000 cases of CIN1 and 7,000–17,000 cases of CIN2/3. Estimated costs to the healthcare service amount to €158.5 million for screening and €22.9 million for the management of cervical abnormalities. Conclusion Although some cervical abnormalities might have been underestimated, the total annual cost of cervical cancer prevention in Italy is approximately €181.5 million, of which 87% is attributable to screening.

    Cervical cancer (CC) is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST). Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL) and CC(p = 0.006, p = 0.036).When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006) and the largest distance compared to NCL-HPV negative ones (p<0.00001). The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings. PMID:27115350

    A discogenic cervical headache is a subtype of cervicogenic headache (CEH) that arises from a degenerative cervical disc abnormality. The purpose of this study was to evaluate the clinical outcome of percutaneous endoscopic cervical discectomy (PECD) for patients with chronic cervical headache due to soft cervical disc herniation. Seventeen patients underwent PECD for intractable headache. The inclusion criteria were soft disc herniation without segmental instability, proven by both local anesthesia and provocative discography for headache unresponsive to conservative treatment. The mean follow-up period was 37.6 months. Fifteen of the 17 patients (88.2%) showed successful outcomes based on the Macnab criteria. Pain scores on a visual analog scale (VAS) improved from a preoperative mean of 8.35{+-}0.79 to 2.12{+-}1.17, postoperatively (P<0.01). The mean disc height decreased from 6.81{+-}1.08 to 5.98{+-}1.07 mm (P<0.01). There was no newly developed segmental instability or spontaneous fusion on follow-up radiography. In conclusion, PECD appears to be effective for chronic severe discogenic cervical headache under strict inclusion criteria. (orig.)

    Full Text Available Background: Although preventable, cervical cancer, an AIDS-related disease, is the second most common cancer amongst South African women and the most common cancer amongst black women. Objective: The objective of the study was to determine what women being treated for HIV and AIDS at a specific healthcare centre in Johannesburg knew about cervical cancer and cervical screening. Method: A survey design was used, with data gathered by means of a self-administered questionnaire. Convenience sampling selected 315 women to participate (n = 315. Descriptive statistics were used to analyse the data and chi-square testing found associations between categorical variables. Results: The majority of respondents (78.7%; n = 248 indicated that they had heard of cervical cancer and 62.9% (n = 198 knew about the Pap smear, with nurses and doctors being the primary source of information. Of the women who knew about the Pap smear, less than one-third had had a smear done, the main reason being fear of the procedure. Conclusion: The study provided evidence that women attending the specific HIV clinic were more knowledgeable about cervical cancer and screening than those of unknown HIV status involved in previous studies. Knowledge was still at a low level, especially when their exceptionally high risk was taken into account. Once again it was found that having knowledge did not necessarily mean having had a Pap smear, which remains a huge challenge in the prevention of cervical cancer.

Es un gran historiador de la ciencia y del pensamiento griegos. En 1940 fue evacuado de Londres con su madre. Sus estudios significativos comenzaron, tras algún rodeo, en el King’s College donde estudiaba su hermano. Éste sería, como su padre, médico, y él mismo dudó en estudiar esa profesión, que late en sus libros. Pero un profesor de clásicas como John Raven –que redactó, con Geoffrey Kirk, Los filósofos presocráticos–, le indujo a ocuparse de la filosofía antigua; y otro maestro, William Guthrie –a quien debemos la gran Historia de la filosofía griega–, le inició, además, en la medicina griega.

  20. Two cases of high cervical cord tumor

    International Nuclear Information System (INIS)

    Two cases of high cervical cord tumor are presented. Case 1 is an intradural extramedullary meningioma located at the foramen magnum. Case 2 is an extradural neurinoma originated from left C2 spinal nerve root. In each case high resolution computed tomography and myelography, especially that of axial view, visualized extramedullary mass lesion.FIn recent years it has been stressed that high resolution computed tomography is useful in the diagnosis of high cervical cord lesion, and this idea is quite reasonable from our experiences. On the other hand, it has been mentioned that myelography often gives false negative results as far as high cervical cord lesion is concerned, which is mainly because relative width of the subarachnoid space in the region of the foramen magnum.FOur experience indicated that in myelographic examination of foramen magnum tumor it is advisable to add axial view to ordinary P-A and lateral views. Bacause axial high cervical myelography gives an image similar to computed tomogram of this region, this technique not only increases the diagnostic value of myelography but also, in some cases, substitutes for computed tomography which costs very much.

  1. Therapeutic Vaccination for HPV Induced Cervical Cancers

    Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

    Worldwide, cancer of the cervix is the second leading cause of cancer death in women: each year, an estimated 500,000 cases are newly diagnosed. Among populations, there are large differences in incidence rates of invasive cervical cancer: these reflect the influence of environmental factors, screening Papanicolaou (Pap) tests, and treatment of pre-invasive lesions. The high-risk human papillomavirus (HPV) subtypes 16, 18, 31, 33, and 51 have been recovered from more than 95% of cervical cancers. We have made great strides in understanding the molecular mechanism of oncogenesis of this virus, focusing on the action of the E6 and E7 viral oncoproteins. These oncoproteins function by inactivating cell cycle regulators p53 and retinoblastoma (Rb), thus providing the initial event in progression to malignancy. Cervical cancers develop from precursor lesions, which are termed squamous intraepithelial lesions (SIL) and are graded as high or low, depending on the degree of disruption of epithelial differentiation. Viral production occurs in low-grade lesions and is restricted to basal cells. In carcinomas, viral DNA is found integrated into the host genome, but no viral production is seen. The well-defined pre-invasive stages, as well as the viral factors involved at the molecular level, make cervical carcinoma a good model for investigating immune therapeutic alternatives or adjuvants to standard treatments.

    Introduction Cervical intraepithelial neoplasias (CIN) represent precursor lesions of cervical cancer. These neoplastic lesions are traditionally subdivided into three categories CIN 1, CIN 2, and CIN 3, using microscopical criteria. The relation between grades of cervical intraepithelial neoplasia (CIN) and its fractal dimension was investigated to establish a basis for an objective diagnosis using the method proposed. Methods Classical evaluation of the tissue samples was performed by an experienced gynecologic pathologist. Tissue samples were scanned and saved as digital images using Aperio scanner and software. After image segmentation the box counting method as well as multifractal methods were applied to determine the relation between fractal dimension and grades of CIN. A total of 46 images were used to compare the pathologist's neoplasia grades with the predicted groups obtained by fractal methods. Results Significant or highly significant differences between all grades of CIN could be found. The confusion matrix, comparing between pathologist's grading and predicted group by fractal methods showed a match of 87.1%. Multifractal spectra were able to differentiate between normal epithelium and low grade as well as high grade neoplasia. Conclusion Fractal dimension can be considered to be an objective parameter to grade cervical intraepithelial neoplasia. PMID:25302712

    Predicting neck response and injury resulting from motor vehicle accidents is essential to improving occupant protection. A detailed human cervical spine finite element model has been developed, with material properties and geometry determined a priori of any validation, for the evaluation of global kinematics and tissue-level response. Model validation was based on flexion/extension response at the segment level, tension response of the whole ligamentous cervical spine, head kinematic response from volunteer frontal impacts, and soft tissue response from cadaveric whole cervical spine frontal impacts. The validation responses were rated as 0.79, assessed using advanced cross-correlation analysis, indicating the model exhibits good biofidelity. The model was then used to evaluate soft tissue response in frontal impact scenarios ranging from 8G to 22G in severity. Disc strains were highest in the C4-C5-C6 segments, and ligament strains were greatest in the ISL and LF ligaments. Both ligament and disc fiber strain levels exceeded the failure tolerances in the 22G case, in agreement with existing data. This study demonstrated that a cervical spine model can be developed at the tissue level and provide accurate biofidelic kinematic and local tissue response, leading to injury prediction in automotive crash scenarios.

    Full Text Available Las rocas graníticas ordovícicas de la sierra de Ancasti representan uno de los afloramientos más orientales del cinturón orogénico famatiniano de Sierras Pampeanas. Se describe un pequeño stock granítico (denominado El Chorro cuyo rasgo distintivo es la presencia de granate. Aunque el granate es un mineral accesorio poco común en rocas ígneas, su presencia es petrológicamente significativa. El Chorro es un monzogranito tipo S que contiene una inusual cantidad de granate magmático (2,8 % modal. Estudios combinados de petrología, química mineral y de geoquímica de roca total sugieren que se trata de un magma peraluminoso generado por la fusión parcial de rocas metasedimentarias, con la subsecuente formación de granate durante la cristalización. Los estudios realizados muestran que el granate cristalizó en equilibrio con otras fases minerales como biotita y muscovita. Cálculos geotermobarométricos revelan una temperatura de cristalización de 710-716 ºC y una presión de 3,8 + 0,8 kbar, indicando que el magma fue emplazado en la corteza media (~ 14 km con temperaturas de cristalización magmáticas medias a bajas.
