Reducción cerrada y osteosíntesis con agujas percutáneas en las fracturas del radio distal

Se presentan 185 casos de fractura compleja del radio distal tratados con reducción ortopédica y estabilización con agujas de Kirschner introducidas de forma percutánea y asociadas a vendaje escayolado antebraquial. Los resultados funcionales finales fueron buenos o excelentes en 156 de los 185 casos (84,3%). Teniendo en cuenta los resultados, consideramos que el método es sencillo, útil y económico y debe valorarse su uso en la mayoría de las fracturas del radio distal.We report 185 cases of distal radius fractures treated by closed reduction and percutaneous Kirschner wire fixation. Final functional results were good or excellent in 156 of the 185 cases (84,3%). In view of the results, we think that the method is simple, useful and cheap, and must value its use in the majority of the distal radius fractures

La fractura-luxación de Monteggia.Tratamiento y pronóstico. A propósito de 35 casos.

Estudio retrospectivo de 35 casos de fractura-luxación de Monteggia tratados entre los años 1990 y 2003. Los resultados fueron satisfactorios en 29 pacientes, regulares en 4 casos y malos en los 2 restantes. Conclusiones: El tratamiento de esta lesión debe ser ortopédico en pacientes en edad infantil. En los adultos, por el contrario, el tratamiento debe ser quirúrgico y consistir en una osteosíntesis estable de la fractura del cúbito, a poder ser con una placa tipo DCP. La reducción de la luxación de la cabeza del radio debe intentarse siempre de forma ortopédica pues los resultados así conseguidos son mejores. Si no es posible, puede intentarse la reducción abierta, evitando siempre que sea posible la exéresis de la cabeza radial. Por otra parte, el diagnóstico y el tratamiento deben realizarse lo más precozmente posible para poder obtener un buen resultado funcional.We present a retrospective study of 35 cases of Monteggia fracture-dislocation treated between the year 1990 and 2003. The results were satisfactory in 29 patients, intermediate in 4 cases and poor in the 2 remaining ones. Conclusions: Treatment of this injury must be orthopaedic in childhood. In the adults, on the contrary, the treatment must be surgical and to consist of a stable osteosynthesis of the fracture of the ulna with a DCP type plate. Reduction of the head of the radius dislocation must be always tried by orthopaedic methods since the results like that obtained are better. If it is not possible, the open reduction can be tried, avoiding providing that there is possible the resection of the radial head. On the other hand, diagnosis and treatment must fulfil early to be able to obtain a good functional result

Fracturas complejas intrarticulares del radio distal. Su tratamiento mediante fijación externa.

Se presentan 135 casos de fractura compleja de radio distal tratadas con fijador externo. Los resultados funcionales fueron buenos o excelentes en 95 de los 135 casos (70,3%). Los resultados radiológicos fueron buenos en 78 de los 135 pacientes (57,8%). Dado el alto porcentaje de fracasos tanto clínicos como radiológicos registrados en nuestra casuística, consideramos que el método debe ser utilizado con precaución, siguiendo una técnica meticulosa que evite las complicaciones relacionadas con su uso.135 cases of complex fracture of the distal radius treated with external fixation are presented. Functional results were good or excellent in 95 of the 135 cases (70,3 %). Radiological results were good in 78 of the 135 patients (57,8 %). In view of the high percentage of both clinical and radio- logical failures observed in our casuistry, we think that the method must be used cautiously, using a careful technique that avoids the complications related to its utilization

Fracturas complejas del radio distal: tratamiento quirúrgico de las fracturas tipo C2

Se presentan 73 casos de fractura de radio distal tipo C2 tratadas en nuestro servicio. Se utilizó como método de osteosíntesis una placa palmar en 3 casos, agujas de Kirschner en 38 casos, fijadores externos en 30 y fijador externo + agujas en 2 casos. Los mejores resultados se obtuvieron en los grupos de casos tratados con placa palmar y con agujas + fijador externo. El fijador externo, aplicado de forma aislada, que "a priori" era el mejor sistema de tratamiento, ha resultado al final ser el procedimiento que se ha visto acompañado de una mayor proporción de secuelas clínicas y consolidaciones viciosas.A total of 73 cases of C2 type fracture of the distal radius treated in our Department are presented. A volar pla- te was used as fixation method in 3 cases, Kirschner wire in 38 cases, external fixator in 30 cases, and external fixator plus Kirschner wire in 2 cases. The best results were obtai- ned in the groups of cases treated with a volar plate and ex- ternal fixator associated with Kirschner wire. The isolated external fixator, that at first was the best system of treatment, has turned out to be the procedure that has been accompa- nied by a greater incidence of clinical sequels and vicious consolidations

Microbiota composition and intestinal integrity remain unaltered after the inclusion of hydrolysed Nannochloropsis gaditana in Sparus aurata diet

The use of lysed microalgae in the diet of carnivorous fish can increase the bioavailability of proteins and bioactive compounds, such as unsaturated fatty acids or vitamins in the digestive tract. These are essential molecules for the proper physiological development of fish in aquaculture. However, some antinutritional components and other undesirable molecules can be released from an excess of microalgae supplied, compromising the integrity of the intestine. The inclusion of small amounts of hydrolized microalgae in the fish diet can be a good strategy to avoid negative effects, improving the availability of beneficial compounds. Nannochloropsis gaditana is an interesting microalgae as it contains nutraceuticals. Previous studies reported beneficial effects after its inclusion in the diet of Sparus aurata, a widely cultured species in Europe and in all Mediterranean countries. However, administration of raw microalgae can produce intestinal inflammation, increased intestinal permeability, bacterial translocation and disturbance of digestion and absorption processes. The aim of this study was to evaluate changes in the intestinal microbiota and barrier stability of S. aurata fed with low inclusion (5%) hydrolysed N. gaditana. Intestinal microbiota was analyzed using Illumina MiSeq technology and libraries were constructed using variable regions V3-V4 of 16S rDNA molecules. Analysis were based in the identification, quantification and comparison of sequences. The predictive intestinal microbial functionality was analyzed with PICRUSt software. The results determined that the intestinal microbiota bacterial composition and the predictive intestinal microbiota functionality did not change statistically after the inclusion of N. gaditana on the diet. The study of gene expression showed that genes involved in intestinal permeability and integrity were not altered in fish treated with the experimental diet. The potential functionality and bacterial taxonomic composition of the intestinal microbiota, and the expression of integrity and permeability genes in the intestine of the carnivorous fish S. aurata were not affected by the inclusion of hydrolysed 5% N. gaditana microalgae

Obtaining cloud top height from WRF model vertical profiles: application to the EUSO program

The objective of the Extreme Universe Space Observatory (EUSO) program is detection and measurement of high-energy particles that reach earth?s atmosphere from space. Clouds at mid and upper levels of the troposphere can interfere with such detection. Therefore, determining cloud top height with high accuracy is crucial to estimating the effect of clouds on these measurements.With this aim, we developed a method to extract that height using cloud temperature via vertical profiles predicted by the WRF model
