    Notes: Seed dormancy in the grain legumes may interfere with germination in some situations, yet is not well described. Dormancy in faba bean (Vicia faba L.) was investigated to determine the mode of inheritance and whether the gene or genes controlling this trait are linked to other genes. Seeds produced by 235 recombinant inbred lines at the F6 generation were used for this study. The parents were the cultivar ‘Optica’ and 172, an Afghanistan landrace which possesses extended seed dormancy. Germination was scored on a seed sample from each recombinant inbred line. Segregation patterns indicated that the trait is monogenic. This gene, named doz, is linked to a gene controlling anthocyanin and proanthocyanidin synthesis, sp-b, with the genetic distance estimated to be about 25 cM. No associations were detected between seed dormancy and pod dehiscence, seed lustre or mean seed weight. The implications of the persistence of a gene for seed dormancy in the gene pool of V. faba for the introgression of traits from landraces and cultivars possessing dormancy and for the origins of domesticated V. faba are discussed.

    Notes: Summary An effective storage procedure has been demonstrated for the mosquito pathogen Culicinomyces clavisporus. A mycelial preparation was harvested by filtration, sprayed with a sucrose solution and air dried at 20°C in a laminar flow cabinet until the mycelial mat became crisp. This material was then ground in a hammer mill and particles of less than 355 μm were sieved out. Viability of the particles was assessed by studying mycelial growth and conidial formation when particles were added to water agar plates or to water. The particles retained 100% viability after 9 weeks storage at-20°C or 6 days at 4°C. Preparations lost activity rapidly if stored at 20°C. Conidia produced by this method were pathogenic to mosquito larvae.

    Description / Table of Contents: Résumé Depuis sa description en 1967, la mortalité du syndrome de détresse respiratoire de l'adulte (SDRA) n'a pas changé malgré les progrès et la sophistication de la réanimation. Peu de patients en effet meurent d'hypoxie réfractaire. La plupart meurent du syndrome de défaillance polyviscérale, le plus souvent dû au sepsis. L'infection est à la fois la cause la plus fréquente du SDRA, le plus souvent d'origine abdominale et intéressant habituellement les poumons. Le SDRA est donc le composant pulmonaire de la défaillance polyviscérale déclenchée par la réponse systémique au sepsis. Chez le patient en état critique, la défaillance hépatique et celle de la barrière mucosale de l'intestin permettent la translocation des endotoxines originaires des germes aérobies Gram-négatifs dans l'intestin. Ceci provoque la libération des médiateurs qui créent des cascades d'activation cellulaire et humorale déterminant les changements pathologiques qui caractérisent le SDRA. Cette séquence souligne l'importance des thérapeutiques dirigées contre la colonisation anormale du tube digestif et l'élimination des stocks d'endotoxines intestinales. La décontamination sélective d l'intestin est intéressante car elle attaque le problème de 2 façons: (a) en supprimant la colonisation elle élimine l'infection secondaire, et (b) elle réduit le stock d'endotoxines intestinales. Les descriptions récentes du rôle de l'oxygène dans le SDRA et le sepsis soulignent la similitude des anomalies physiopathologiques dans les 2 conditions. Une thérapeutique intensive pour assurer un transport d'oxygène suffisant et une attitude diagnostique et thérapeutique aggressive des foyers septiques sont la clé du traitement du SDRA établi.
    Abstract: Resumen Desde su descripción en 1967, la mortalidad del síndrome de dificultad respiratoria del adulto (SDRA) ha permanecido invariable a pesar de una creciente sofisticación de las técnicas de soporte. Pocos pacientes fallecen en la actualidad de hipoxemia refractaria; la mayoría muere más bien por causa del síndrome de falla orgánica múltiple, generalmente debido a sepsis. La sepsis, principalmente cuando esta ubicada en el abdómen, es la causa más frecuente de SDRA, y también su más frecuente complicación, generalmente con afección pulmonar. El SDRA se ve con creciente frecuencia como el componente pulmonar de la falla orgánica múltiple, activado por la respuesta sistémica a la sepsis. En los pacientes en estado crítico la alteración de la función hepática y de la barrera de la mucosa intestinal permiten la translocación de la endotoxina derivada de las bacterias Gramnegativas en el interior del intestino. Esto resulta en la liberación de mediadores que son responsables de la activación de las cascadas celular y humoral causantes de los cambios patológicos del SDRA. Esta secuencia de eventos señala la importancia de la terapia dirigida contra la colonización anormal del tracto gastrointestinal y la eliminación del reservorio de endotoxina intestinal. La descontaminación selectiva del tracto digestivo es un concepto atractivo porque ataca el problema desde 2 ángulos diferentes: en primer lugar la eliminación de la colonización parece ser eficaz en cuanto a evitar la infección secundaria y, en segundo lugar porque puede jugar un papel en la eliminación del reservorio de endotoxina. Recientes informes sobre la dependencia patológica de la provisión de oxígeno que se observa tanto en el SDRA como en la sepsis, resaltan la similitud de las alteraciones patofisiológicas en las 2 entidades. Una intensa terapia de soporte para lograr un adecuado transporte de oxfgeno, más la identificación y el manejo quirúrgico agresivos de los focos sépticos, constituyen los baluartes del manejo del sfndrome ya establecido.
    Notes: Abstract Since its first description in 1967, the mortality of the adult respiratory distress syndrome (ARDS) has remained unchanged despite the increasing sophistication of supportive techniques. Few patients now die of refractory hypoxemia, the majority succumbing to the multiple systems organ failure syndrome, commonly due to sepsis. Sepsis is both the most common cause of ARDS, usually involving the abdomen, and the most frequent complication, usually affecting the lungs. ARDS is, thus, increasingly seen as the pulmonary component of multiple systems organ failure, triggered by the systemic response to sepsis. In critically ill patients, impairment of hepatic function and of the barrier function of the gut mucosa allows translocation of endotoxin derived from the aerobic Gram-negative bacteria within the gut. This releases mediators which are responsible for the activation of cellular and humoral cascades, resulting in the pathological changes seen in ARDS. This sequence of events underlines the importance of therapies directed at abnormal colonization of the gastrointestinal tract and elimination of the gut endotoxin pool. Selective decontamination of the digestive tract is attractive in that it attacks the problem from 2 sides: first, by eliminating colonization, it appears effective in preventing secondary infection and, second, it may also play a role in reducing the enteric endotoxin pool. Recent descriptions of pathological oxygen supply dependency in both ARDS and septic patients emphasize the similarity of pathophysiological abnormalities in the 2 conditions. Intensive supportive therapy to achieve adequate oxygen transport and aggressive investigation and surgical management of septic foci are the cornerstones of management of the established syndrome.

    Notes: Abstract Objective: To describe current arrangements for postgraduate training and speciality status for intensive care medicine in Europe, and to compare these with three other geographical regions: the Middle East, North America, and Australia and New Zealand. Methods: An iterative survey, by questionnaire and direct discussion, of council members of the European Society of Intensive Care Medicine, national specialist societies with involvement in intensive care, and national experts, representing four geographical regions and 47 countries. Results: For the purposes of analysis, countries with common training structures have been grouped together; the denominator therefore includes both countries and regions. Formal training programmes in intensive care medicine (ICM) are available in 18 (85 %) of the 21 countries or regions surveyed. Twelve (57 %) offer multidisciplinary access to intensive care training with a common core curriculum. In six (28 %) training in ICM is available solely through anaesthesia. The duration of intensive care training required for recognition as a specialist in the 18 countries or regions with a formal programme ranges from 18 to 30 months, with a median of 24 months. All countries assess competence in intensive care, but methods for doing so vary widely. Eighteen countries or regions offer specialist registration (accreditation) in ICM; in 12 this is provided as dual accreditation in a base speciality and in ICM. Conclusions: There is substantial support for multidisciplinary training in ICM, as demonstrated by collaborative interspeciality developments in many countries. We propose that these national developments should be strengthened within Europe by the recognition of ’supra-speciality' status for ICM by the European Commission, and by the establishment of a multidisciplinary Board for training in ICM, with international agreement on core competencies and duration of training programmes, and a common approach to the assessment of competence through formal examination.

    Notes: Abstract Acquired infection is a common problem in intensive care and in a general ICU the infection rate can exceed 80% in patients ventilated beyond 5 days. SDD, adapted from regimes used in neutropenic patients, was first introduced to the ICU situation in Groningen. This article reviews 10 published trials of SDD in ICU. The trial designs vary but all show a significant reduction in both colonisation rates and acquired infection rates. Infection rates were reduced from 10%–78% to 3%–10% in the SDD treated groups. Of the 10 trials 2 showed an overall reduction in mortality 2 showed a reduction in infection-related mortality and 1 showed a reduction in mortality amongst trauma patients. Although further evaluation of trials is required SDD now appears to be of proven efficacy in certain groups of high risk patients within ICU.
