Ensayos de inmunización en pequeños rumiantes con proteinasas tipo cisteína de vermes adultos de Haemonchus contortus: implicaciones en la variabilidad genética del parásito

[ES] Los problemas asociados al uso de antihelmínticos en el control de las nematodosis gastrointestinales, tales como la presencia de residuos en alimentos de origen animal o la aparición de resistencias han estimulado el estudio del control inmunológico de numerosas parasitosis.

Sistema de vigilancia autónomo multiagente

[ES] En este proyecto se ha llevado a cabo el análisis, diseño e implementación de un software para la gestión y monitorización de sistemas de cámaras con el objetivo de su uso en la vídeo vigilancia. El propósito de este software es asistir a un operador humano en las labores de supervisión de zonas monitorizadas. Se trata de un software con interfaz multiplataforma y multihilos capaz de manejar un conjunto de cámaras estacionarias (sin importar tipo y marca) en escenarios interiores o exteriores. Durante la realización de este PFC se han estudiado y tratado problemas relacionado con las interfaces perceptuales hombre-máquina, técnicas de detección y seguimiento de objetos, manejos de base de datos, etc., con el objetivo de obtener un software modulado, eficiente y robusto.

La traducción del género básico del pop de los 80 y 90: aspectos etimológicos, históricos y culturales

[ES] Esta investigación tiene como objeto la defensa de la traducción de las letras de las canciones para el aprendizaje de lenguas extranjeras, entre otras razones. Nuestra hipótesis se sustenta en la definición del texto musical pop como poesía cantada enmarcada, a su vez, dentro del concepto de discurso poético. A este respecto, nos inclinamos por una descripción motivada del género musical pop en su vinculación con la recepción y sus receptores. A partir de la concepción de género como enfoque lingüístico de los diferentes tipos de discurso, llegamos a la conclusión de que existe una confusión entre el pop como categoría supraordinada y los estilos de él derivados. No obstante, también debemos trabajar categorías estéticas, dado que en el texto musical conviven, a su vez, dos textos interrelacionados: la música y la letra. Nuestro estudio contempla las traducciones dentro de las subordinaciones del medio escrito y las limitaciones impuestas por el lenguaje poético.

What is the diagnostic value of ultrasonography compared to physical evaluation in patients with idiopathic carpal tunnel syndrome?

[EN] OBJECTIVE: Our hypothesis is that sonography performed by the rheumatologist in patients with suspected carpal tunnel syndrome (CTS) has higher diagnostic value compared to physical evaluation. METHODS: Adult patients with suspected idiopathic CTS, defined by sensory symptoms over the distribution of the median nerve with or without positive results with the Phalen and/or the Tinel's maneuvers were included. The diagnosis of CTS was indicated by typical symptoms daily for at least 3 months and a positive nerve conduction study. One rheumatologist unaware of the clinical and electrodiagnostic results performed an ultrasound examination of the median nerve for the area ranging from the inlet to the outlet of the carpal tunnel. Mean cross-sectional area at each level, flattening ratio and bowing of flexor retinaculum were obtained. RESULTS: Sixty-eight patients with 105 affected wrists were examined. Tinel's and Phalen's signs had a closer sensitivity (73% and 67% respectively) and specificity (40% and 30% respectively). The best swelling nerve cut-off by sonography was 9.7 mm2 at the tunnel inlet, with a sensitivity of 86%, a specificity of 48% and accuracy of 77%. A 100% positive predictive value was reached with a cross-sectional area of 13 mm2, involving 33 hands (31% of the whole sample). Maximal cross sectional area and the measurement of flexor retinaculum had an accuracy of 72% and 73% respectively. Combination of physical maneuvers and sonography not yielded more accuracy than cross-sectional area itself. CONCLUSION: In patients with clinical history of idiopathic CTS and positive nerve conduction study, sonography performed by the rheumatologist has higher diagnostic value than physical maneuvers.

Limited value of ultrasound assessment in patients with poor outcome after carpal tunnel release surgerys

[EN] OBJECTIVE: To determine the value of ultrasonography in the assessment of patients with idiopathic carpal tunnel syndrome (CTS) and poor outcome after carpal tunnel release. METHODS: A total of 88 consecutive patients with CTS (104 hands) underwent open surgical release of the median nerve. Ultrasound (US) examination was performed blind to any patient's data. The median nerve area at tunnel inlet and outlet, the retinaculum distance, and the flattening ratio were measured. The main outcome variable was the patient's overall satisfaction using a five-point Likert scale (1 = worse, 2 = no change, 3 = slightly better, 4 = much better, 5 = cured) at 3 months postoperatively. Pre- and postoperative ultrasonographic findings in relation to clinical outcome were analysed. RESULTS: Improvement (scores 4 or 5 on the Likert scale) was recorded in 75 hands (72%). After carpal tunnel release, the cross-sectional area at tunnel inlet decreased from a mean of 14.2 to 13.3 mm2 in the group with clinical improvement and also from a mean of 12.5 to 11.6 mm2 in the group with no change or slight improvement. No significant changes in the cross-sectional area at tunnel outlet, retinaculum distance, and flattening ratio were observed. CONCLUSION: Reduction of the median nerve cross-sectional area at tunnel inlet at 3 months after carpal tunnel release was similar in patients reporting cure or great improvement and in those with slight or no improvement. Ultrasonography is of limited value in assessment of patients with poor outcome after median nerve release.
