Resumen en español Los microscopios de barrido se han convertido en las manos y los "ojos" de experimentadores de nuestro siglo, son herramientas necesarias en los laboratorios de educación e investigación para la caracterización a nanoescalas. El presente artículo presenta las modificaciones en la implementación electrónica (caracterización de los piezoeléctricos y sistema de barrido) y mecánica (diseño de un sistema de antivibración) de un microscopio de barrido de efecto túne (mas) l que han permitido visualización y modificación de superficies a nanoescala. Se describe una metodología para la correcta visualización y caracterización de superficies usando el instrumento implementado, alcanzando la cuantificación bidimensional de características de hasta 1300nm², con resolución ~15nm. Esta metodología, determinada experimentalmente, tiene en cuenta parámetros críticos para la estabilización de la corriente túnel, como lo son la velocidad de barrido y las geometrías y dimensiones de las agujas del microscopio. La versatilidad del microscopio permite modificar y visualizar los defectos introducidos en muestras de HOPG al aplicar voltajes entre la punta del microscopio y la muestra. Los resultados aquí descritos permiten presentar fácilmente los conceptos de barrido topográfico y litografía. Resumen en inglés Sweeping/scanning microscopes have become an experimental scientist's hands and eyes in this century; they have become a powerful and necessary tool for nanoscale characterisation in education and research laboratories all around the world. This article presents the modifications made in the mechanical (isolation or designing an antivibration system) and electrical (piezoelectric and scanning system characterisation) implementation of a scanning tunnelling microscope (STM (mas) ), thereby allowing nanoscale surfaces to be visualised and modified. A methodology for visualising and characterising surfaces using the aforementioned instrument is described, bidimensional quantification of up to 1,300 nm², with ~15 nm resolution being reached. This experimental methodology took critical parameters for tunnelling current stability into account, such as scanning speed and microscope tip geometry and dimensions. This microscope's versatility allowed defects in highly oriented pyrolytic graphite (HOPG) samples to be modified and visualised by applying a voltage between the tip and the sample. The concepts of topography scanning and lithography can be easily understood by using the instrument implemented here.

Resumen en español Las algas rojas coralinas asimilan HCO3- para precipitar CaCO3 en sus tejidos en forma de calcita o aragonita. Se realizó una caracterización del contenido biomolecular así como de la estructura cristalina del biomineral en algas rojas coralinas de las costas del Pacífico mexicano mediante difracción de rayos X (XRD) en polvos, microscopía electrónica de barrido (MEB) y de túnel (STM), y espectroscopía infrarroja con transformada de Fourier (FTIR). Con los result (mas) ados se llegó a la conclusión preliminar de que este tipo de calcita-aragonita tiene un muy bajo contenido de materia orgánica ocluida dentro de los cristales. Las bandas de FTIR a 2945 y 2889 cm-1 encontradas indican que las moléculas orgánicas más probables son los hidratos de carbono; además, no se detectaron bandas de enlace peptídico (amida I ~1640 y amida II ~1540 cm-1), lo que sugiere que las proteínas no están relacionadas con la síntesis mineral o con su estabilización. Esto se podría explicar si el biomineral fuera sintetizado por un proceso extracelular de mineralización controlado biológicamente. El análisis de XRD mostró dos fases minerales principales, calcita y aragonita, muy similares en sus parámetros estructurales a sus contrapartes minerales inorgánicas pero con modificaciones en la estructura molecular. Las formas y tamaños de los cristales, vistos mediante STM, son típicamente en placas y agujas de diferentes tamaños, entre 20 y 100 nm. Resumen en inglés Coralline red algae assimilate HCO3- to precipitate CaCO3 in their tissues in the form of calcite or aragonite. A characterization of the biomolecular content and the crystalline structure of the biomineral of coralline red algae from the Pacific coast of Mexico was performed by powder X-ray diffraction (XRD), scanning electron (SEM) and tunneling microscopy (STM), and Fourier transform infrared spectroscopy (FTIR). The preliminary conclusion drawn from the results is tha (mas) t this type of calcite-aragonite biomineral has a very low organic content occluded within the crystals. FTIR bands at 2945 and 2889 cm-1 indicate that the most likely organic molecules are carbohydrates; moreover, peptide bond bands (amide I ~1640 and amide II ~1540 cm-1) were not detected, suggesting that proteins are not related to mineral synthesis or their stabilization. This could be explained if the biomineral is synthesized by a biologically controlled extracellular mineralization process. The XRD study showed two main mineral phases, calcite and aragonite, with very similar structural parameters to the inorganic mineral counterparts. The crystallite shapes, seen by STM, were found as plates and needles with different sizes, between 20 and 100 nm.

Resumen en español Objetivo: Resumir las lecciones aprendidas despues de haber realizado más de 250 intervenciones de inserción de la malla AdVance®.La incontinencia después de la prostatectomía es una realidad deprimente, frecuentemente subestimada por el cirujano. El esfínter urinario artificial ha sido el "gold standard" en el tratamiento de la incontinencia urinaria severa. No existe un consenso similar para la incontinencia leve-moderada. Este artículo trata sobre una operación (mas) para la incontinencia con el objetivo de dar soporte a la laxitud del esfínter uretral después de la prostatectomía. Método: La hipótesis de la laxitud esfinteriana post-prostatectomía es nueva, así como la restauración de la continencia mediante la reubicación proximal del cuerpo esponjoso proximal. Resumimos los trabajos que tratan este tema. Destacamos puntos seleccionados de la técnica quirúrgica, incluyendo las modificaciones que se han introducido con la experiencia. Finalmente, comparamos los primeros y últimos 20 pacientes tratados en esta serie de 250 pacientes, analizando indicación quirúrgica, técnica quirúrgica y resultados del tratamiento. Añadimos algunas definiciones para aportar claridad. Resultados: Se pudo demostrar que la posición final del AdVance® es retroluminal, es decir 5-10 mm dorsal/detrás de la luz de la uretra membranosa (= uretra esfinteriana). Comparando los primeros y últimos 20 casos, en estos últimos no hay ningún fracaso del tratamiento. El seguimiento a dos años muestra una tasa de continencia del 65% en el primer grupo comparada con el 85% del segundo, teniendo en cuenta una mediana de tiempo de seguimiento corta en el segundo grupo, de 4,1 meses. La tunelización subcutánea del cabestrillo disminuyó significativamente el aflojamiento postoperatorio. Conclusiones: El cabestrillo AdVance® es un método seguro de tratamiento de la incontinencia urinaria leve-moderada postprostatectomía, con ausencia de erosiones en esta serie. La hipótesis de la laxitud esfinteriana parece desempeñar un papel definitivo en la fisiopatología de la incontinencia masculina. La corrección de este descenso del soporte uretral o "prolapso" parece ser altamente eficaz. Son necesarios nuevos estudios para definir precisamente el mecanismo exacto de acción del cabestrillo AdVance® Resumen en inglés Objectives: To summarize the lessons learnt after having performed more than 250 AdVance® sling procedures. Postprostatectomy incontinence is a depressing reality that is often underestimated by the prostate surgeon. The practiced gold standard for treating severe stress urinary incontinence has been the artificial urinary sphincter. No such consensus exists for mild to moderate incontinence. This paper is about an incontinence operation with the goal to support postpros (mas) tatectomy sphincter laxity. Methods: The hypothesis of postprostatectomy sphincter laxity is new, as well as restoring continence by proximal relocation of the proximal corpus spongiosum. Abstracts dealing with these issues are summarized. Selected points of technique are highlighted, including modifications that have been made along the way. Lastly the first and last 20 patients treated in this series of 250 patients are compared in terms of operative indication, surgical technique and treatment outcome. Some definitions are added for clarity. Results: It could be demonstrated that the final position of the AdVance® sling is retroluminal, i.e. 5-10mm dorsal/ behind the lumen of the membranous urethra (=sphincteric urethra). Comparing the first 20 to the last 20, there were no treatment failures in the latter. A two year follow-up showed a continence rate of 65% in the first group, compared to a 85% continence rate in the second group taking into account the short median follow-up of 4.1.months in the latter. Tunneling the sling subcutaneously decreased postoperative loosening significantly. Conclusion: The AdVance® sling is a safe method of treating mild to moderate postprostatectomy incontinence, with no erosions in this series of patients. The hypothesis of sphincter laxity seems to play a definitive role in the pathophysiology of male incontinence. Correction of this urethral support descent or "prolapse" seems to be highly effective. Further studies are needed to accurately define the exaxt mechanism of action of the AdVance® sling.

Resumen en español OBJETIVO: La patología de la uretra ha suido siempre un interesante tema de estudio, apareciendo ya en los textos de 600 años a.C., donde se describen los dilatadores de madera y metal. En la época judeo-musulmana aparecen las primeras uretrotomías externas, y Francisco Díaz describe en 1588 el tratamiento de las carnosidades de la verga. Con Civiale y Maisoneuve, entre 1700 y 1800, aparece la descripción del uretrotomo, y finalmente a mediados del siglo XIX, se com (mas) ienza con la búsqueda de tejidos capaces de sustituir a la uretra. MÉTODOS: Revisamos todos los artículos de los autores valencianos de la época referidos a la patología uretral, publicados fundamentalmente la Revista Valenciana de Ciencias Médicas. RESULTADOS: Destacamos el uso de las bujías y sondas en el abordaje de la patología estenótica uretral, por varios autores, con sus ventajas e inconvenientes. Asimismo, la descripción de una uretrotomía externa por el Prof. Mollá. Finalmente destacamos el tratamiento de una rotura de uretra posterior mediante tunelización por el Dr. Alfredo Tramoyeres. CONCLUSIONES: A pesar de no ser una patología con un alto volumen de publicaciones, ha interesado desde siempre a los autores. Exponemos todos los tratamientos, técnicas de sondaje y la dilatación como primera opción. Resumen en inglés OBJECTIVES: Urethral pathology has always been an interesting topic for study, being present in texts from 600 years B.C, where wood and metallic dilators are described. First external urethrotomies appear in the Jewish-Muslim period, and Francisco Diaz describes in 1588 the treatment of the prostate in his book "Tratamiento de las carnosidades de la verga". With Civiale and Maisoneuve, between 1700 and 1800, appears the description of the urethrotome, and finally in the (mas) middle XIX century starts the search for adequate tissues to replace urethra. METHODS: We review all articles on the topic of urethral pathology from authors from Valencia in that period, mainly published in the journal "Revista Valenciana de Ciencias Médicas". RESULTS: We emphasize the use of bulbs and sounds in the approach to urethral stenosis by several authors, with their advantages and limitations. We also emphasize the description of external urethrotomy by Prof. Molla. Finally, we point out the treatment of a posterior urethra fracture by tunneling reported by Dr. Alfredo Tramoyeres. CONCLUSIONS: Despite not being a topic with a high volume of publications, it has always interested authors. We describe all treatments, and sound insertion and dilation techniques as first option.

Resumen en español Diatraea saccharalis es la plaga del cultivo de maíz de mayor impacto económico en la región pampeana de la Argentina. Las larvas ocasionan pérdidas por daños de tipo fisiológico y mecánico. Las pérdidas por daño mecánico aumentan a medida que se retrasa la fecha de cosecha, y una de las medidas culturales para prevenirlas es la cosecha anticipada. El objetivo de este trabajo fue estudiar la relación entre el número de entrenudos con galerías producidas por l (mas) arvas grandes y el número de orificios por planta ocasionados por D. saccharalis. El estudio se realizó en Manfredi (Córdoba, Argentina) durante la campaña agrícola 1999/2000. Se siguió un diseño experimental en parcelas divididas con cinco fechas de siembra y dos niveles de protección con insecticidas (protección total y libre infestación), como factores. Se evaluaron los ajustes a seis modelos mediante análisis de regresión lineal y no lineal. El porcentaje de plantas quebradas por debajo de la espiga varió de 3,4 a 30%. El modelo lineal explicó muy bien la relación entre el número de orificios por planta y el número de entrenudos con galerías del barrenador (R2 =0,95), y para fines predictivos resultó el más adecuado. Resumen en inglés Diatraea saccharalis is economically the most important pest to corn crops in the Pampa region in Argentina. The tunneling produced by the larvae has negative consequences due to both physiological and mechanical damage (stem falling and ear dislodging). Losses caused by mechanical injuries increase as harvest is delayed, so one of the cultural methods to prevent them is to anticipate harvest. The objective of this work was to study the relationship between the number of (mas) bored internodes and the number of holes produced by large D. saccharalis larvae in the stem. The study was perfomed in Manfredi (Córdoba, Argentina) during the 1999/2000 growing season. It was carried out using a split plot design with five planting dates and protection category (with and without insecticide) as treatments. Six models were evaluated by means of linear and non linear regression. The percentage of stems broken below the ear ranged from 3.4 to 30%. The linear model provided a good description of the relationship between the number of bored internodes and the number of holes per plant (R² =0.95) and resulted in the best option for predictive purposes.

Del camino recorrido por la cirugía para tratar la enfermedad coronaria.: Trabajo dedicado como homenaje póstumo al Dr. René Favarolo/ A short history of coronary surgery.: Apropos of Dr Favaloro’s death

2001-02-01

Resumen en inglés The first surgical procedure for the treatment of coronary artery disease, in 1933, was total thyroidectomy. Some years later, procedures to increase heart irrigation such as pectoral or great epiplon grafting and cardiopeumopexy were attempted. In 1940, the ligation of great cardiac vein or coronary sinus were introduced. Five years later, pericoronary neurectomy was used. In 1945, Beck used an arteriovenous fistula between the descending aorta and the coronary sinus and (mas) , from 1954, he used the erosion of heart surface with asbestos application, complemented with the occlusion of the coronary sinus and the application of parietal pericardium. In 1958, Glover introduced the bilateral ligation of mammary arteries and Vineberg, developed the internal mammary artery implant, that consisted in the tunneling of the free portion of such artery in the myocardium. En 1956, Lillehei and Bailey introduced coronary endarterectomy and finally in 1967, Favaloro introduced systematically the aortocoronary bypass using safenous vein, that became the definitive surgical treatment for coronary artery disease. In Chile the first coronary surgery was done by Torwall and Uribe in 1950 and modern coronary surgery was initiated by Salvestrini in1970 (Rev Méd Chile 2001; 129: 201-08)

Resumen en español Se presentan 4 pacientes con enfermedad renal crónica en terapia hemodialítica en quienes se habían agotado los accesos venosos clásicos (yugular interno, subclavio) y no clásicos (axilar e innominado) en el hemitórax superior para hemodiálisis, debido principalmente a trombosis de los mismos por cateterismos anteriores, y que no eran candidatos a diálisis peritoneal. En ellos, con la técnica recomendada por Archundia et al., se implantaron 4 catéteres permanent (mas) es directamente en la vena cava superior, con posterior tunelización subcutánea. Los catéteres funcionaron adecuadamente y están permeables actualmente después de un período de utilización promedio de 19 meses. Resumen en inglés We report four patients with chronic kidney disease undergoing haemodialysis therapy, which had exhausted conventional venous access (internal jugular, subclavian) and non-conventional access (axillary, innominate) in the upper hemithorax for haemodialysis. This was primarily due to thrombosis of these veins caused by previous catheterisation. These patients did not qualify for peritoneal dialysis. Using the technique recommended by Archundia et al., 4 indwelling catheter (mas) s were implanted directly in the superior vena cava in each of the patients with subsequent subcutaneous tunneling. The catheters operated correctly and are currently permeable after being used for an average of 19 months.
