Abstract: El avance en el ámbito de los accesos en la diálisis peritoneal plantea cuestiones que requieren su discernimiento y su posible solución. Una de las causas más comunes de los problemas mecánicos es el atrapamiento por el omento o el estre imiento. Otros factores que pueden afectar al buen funcionamiento de un catéter de diálisis peritoneal es la existencia de adherencias y/o hernias en la zona abdominal. En nuestra unidad de diálisis peritoneal se utilizan catéteres autoposicionantes y no autoposicionantes (Tenckhoff), por lo que decidimos realizar un estudio a fin de comparar que diferencias existen en su vida de funcionamiento. Nuestro objetivo ha sido comparar las diferencias existentes referidas a complicaciones por desplazamiento y malposición entre los dos tipos de catéteres. Y valorar si la obesidad, la cirugía abdominal previa y el tiempo de permanencia son variables que influyen en el buen funcionamiento de los catéteres. La muestra estudiada pertenece a pacientes que actualmente están en activo en el programa de diálisis peritoneal en nuestra unidad. Se contabilizaron 35 pacientes. El 60% era portador de catéter autoposicionante y el 40% Tenckhoff. Un 37.4% de los pacientes había sido intervenido a nivel abdominal y/o pélvico. Solo un 28.57% eran obesos (con un índice de Masa Corporal> 30) con una media de peso de 72.8±18.9 Kg. Los catéteres fueron implantados con cirugía abierta, anestesia local y sedación por lo que se realizaba de forma ambulatoria. Para la elección del catéter se utilizó una correlación numérica aleatoria. El catéter Tenckhoff es un tubo de silicona con múltiples orificios distales y que puede terminar de forma recta o enroscada. También presenta un dacron para evitar las infecciones del orificio. El catéter autoposicionante tiene la misma forma que un catéter Tecnckoff pero con una modificación. En su extremo distal tiene un aumento del diámetro de unos dos centímetros, que es el a adido de un peso de 12 gramos de un material biocompatible (tungsteno) que favorece que el catéter esté siempre en la parte inferior de la cavidad peritoneal, evitando el mal funcionamiento por desplazamiento. Para analizar las complicaciones mecánicas de ambos tipos de catéteres recogimos las ocasiones en las que se utilizaba un evacuante intestinal (X-Prep) y en las que había sido necesaria una recolocación en quirófano (utilizando únicamente un fiador para su recolocación y sin necesidad de anestesia local). Se realizó una hoja de recogida de datos en la que se anotaron todas las variables: sexo, edad, tiempo en diálisis peritoneal, índice de

Abstract: La investigación en nefrología pretende encontrar técnicas cada vez más eficientes de depuración extrarrenal. La técnica dialítica biofiltración sin acetato con perfil de potasio pretende ofrecer una mejor tolerancia y reducir el riego de arritmias. Nuestro objetivo fue comparar está técnica con la hemodiálisis de alto flujo y la hemodiafiltración con el fin de averiguar que tratamiento dialítico es más adecuado para cada paciente. Estudio controlado, prospectivo y cruzado en el cual los mismos pacientes han sido su propio control. La elección de los pacientes y de la técnica fue aleatoria dializándose los pacientes durante 13 sesiones consecutivas con cada una de las técnicas objeto del estudio. Durante todo el estudio se mantuvieron constantes los siguientes parámetros de diálisis: duración de la sesión, flujo, calibre de las agujas y dosis de heparina. A los quince días de comenzar cada período se realizó a los pacientes un electrocardiograma y una analítica (todo pre y post diálisis). En las técnicas biofiltración y hemodiafiltración el valor del bicarbonato es más fisiológico. Con la biofiltración y la hemodiálisis de alto flujo se consigue una mejor corrección del equilibrio ácido-base. En cuanto a los valores de sodio existen peque as diferencias en las tres técnicas estando éstos en todo momento dentro del intervalo fisiológico. En la hemodiafiltración los episodios de arritmias aumentaron. Los tres métodos han demostrado una correcta eficacia dialítica, tolerancia y estabilidad cardiovascular. Research in nephrology seeks to find increasingly efficient extrarenal purification techniques. The dialysis technique of potassium-profiled acetate-free biofiltration offers better tolerance and reduces the risk of arrhythmias. Our aim was to compare this technique with high-flow haemodialysis and with haemodiafiltration in order to ascertain which dialysis treatment is the most suitable for each patient. A prospective, controlled cross study in which the same patients were their own control group. The choice of patients and technique was random, with the patients undergoing 13 consecutive sessions of dialysis with each of the techniques being studied. Throughout the study, the following dialysis parameters were kept constant: duration of the session, flow, calibre of the needs and dose of heparin. Fifteen days after starting each period, patients were given an electrocardiogram and blood test (all pre and post dialysis). With the biofiltration and haemodiafiltration techniques the bicarbonate value is more physiological. With biofiltration and high-flow

Abstract: the advances made in the field of accesses in peritoneal dialysis raise questions that require discernment and a possible solution. one of the most common causes of mechanical problems is omental entrapment or constipation. other factors that can affect correct functioning of a peritoneal dialysis catheter is the existence of adhesions and/or hernias in the abdominal area. in our peritoneal dialysis unit, self-locating and non-self-locating (tenckhoff) catheters are used, and therefore we decided to carry out a study to compare the differences in their operating life. our aim was to compare the differences concerning complications due to displacement and incorrect positioning between the two types of catheter, and also to evaluate whether obesity, prior abdominal surgery and the time the catheter is in place are variable that affect correct functioning of the catheters. the sample studied comprised patients who are currently active on the peritoneal dialysis programme in our unit. a total of 35 patients were studied. 60% had a self-locating catheter and 40% a tenckhoff catheter. 37.4% of the patients had undergone abdominal and/or pelvic surgery. only 28.57% were obese (with a body mass index > 30) with an average weight of 72.8±18.9 kg. the catheters were implanted using open surgery, local anaesthetic and sedation and therefore in on an ambulatory basis. random numerical correlation was used for the choice of catheter. the tenckhoff catheter is a silicon tube with multiple distal orifices and which can have a straight or threaded tip. it also has a dacron cuff to prevent infections of the orifice. the self-locating catheter has the same form as a tenckhoff catheter but with a modification. at the distal tip it has an increased diameter of two centimetres, which is the result of adding a 12-gramme weight made of a biocompatible material (tungsten) to favour the positioning of the catheter always in the lower part of the peritoneal cavity, avoiding malfunction due t

Abstract: patients on haemodialysis are becoming increasingly older and this means there is an increase in the number of vascular access complications. infections of tunnelled catheters cause a high morbidity/mortality. the tego? microbiologically and mechanically sealed connector is used instead of the conventional cap used to close the catheter ends, and has the advantage that it is only changed once a week. this means that as there is less handling of the central venous catheter, fewer complications and infections appear. it also offers a double security barrier against the entry of air and exit of blood represented by the catheter clamp and the cap. to evaluate this device, we have carried out a study in which we compared the tego? connectors with conventional caps, analysing the following aspects: circuit pressures, dialysis efficacy and catheter infections. the study lasted for two months and included the participation of twelve patients using a tunnelled catheter. our results show that there are no significant differences with regard to circuit pressures and dialysis efficacy between the two different types of caps. during the study there was no pericatheter infection. we believe that the tego? device, on account of its special characteristics, may be the ideal closure system for all kind of catheters.

Abstract: K-casein (K-CN) represents one of the most important proteins determining the manufacturing properties of milk, because of its essential role in micelle formation and stabilisation. Several genetic variants of K-CN have been described in goats. To investigate the occurrence of seven alleles and their distribution among breeds, a total of 170 animals, from six different breeds reared in Italy (Cilentana Nera, Derivata di Siria, Maltese, Jonica, Garganica and Cashmere), have been analysed in this paper by the primer extension method. Alleles A and B were found to be the most represented in all the analysed breeds; allele D is present only in Maltese and Cashmere animals with a very low frequency; while allele G has been found in all but two (Garganica and Cashmere) breeds. Alleles C, E and F were not present in the material used for this study.
