Multiple system organ failure after cardiac surgery in children is a severe complication with unknown mid- and long-term sequelae. We therefore evaluated 11 children (aged 20-126 mo, median: 67 mo) having survived multiple system organ failure after cardiac operations for congenital cardiac defects in a cross-sectional follow-up study 12-76 mo (median: 32 mo) after surgery. Clinical and laboratory examinations included cardiac, pulmonary, renal, hepatic, neurological and psychological function tests. All patients had adequate cardiac function. Lung mechanics were abnormal in three children and glomerular renal function was abnormal in two patients. Slight elevation of gamma-glutamyl transpeptidase and coagulation factor deficiency was present in six and seven patients, respectively (five of whom had undergone the Fontan operation). Severe neurological sequelae such as diplegia (n = 1) and mental retardation (n = 1) were observed in two patients. In addition, five children presented delayed motor, graphomotor and/or speech development. Two children were found to have abnormal intelligence. We conclude that with the exception of neurological impairment, mid-term sequelae of multiple system organ failure after cardiac surgery in children are mild. However, longer follow-up using an appropriate control group is mandatory. [less ▲]

OBJECTIVE AND DESIGN: Because high concentrations of histamine are locally released in inflammation, we investigated the effects of supraphysiological doses of histamine on the production of reactive oxygen species (ROS) by neutrophils. MATERIALS AND METHODS: Isolated equine neutrophils were activated by 10(-4) to 5 x 10(-3) M histamine. The production of ROS and free radicals was estimated by luminol-enhanced chemiluminescence (CL) and electron spin resonance (ESR) with spin trapping technique. In this model of histamine-stimulated neutrophils, we tested the antagonists of H1 and H2 histamine receptors, the role of Ca2+ and Mg2+, the role of staurosporine and pertussis toxin (inhibitors of protein kinase C and proteins G) and the effects of superoxide dismutase, catalase, hydroxyl radical scavengers (phenylalanine and mannitol) and N(G)-monomethyl-L-arginine (L-NMMA), inhibitor of NO-synthase. RESULTS: Histamine (from 10(-5) to 10(-3) M) stimulated neutrophils to produce CL and ESR signals characterized by spin adducts of superoxide anion and/or hydroxyl radicals. The CL response was inhibited by 10(-4) and 10(-3) M H1 receptor antagonists (promethazine, pyrilamine, and diphenhydramine), by Ca2+ and Mg2+ depletion and by 10 nmoles staurosporine. CL was partially inhibited by pertussis toxin (4 microg/ mL). The ESR signals were practically suppressed by pyrilamine (an H1 receptor antagonist) and superoxide dismutase, and partially inhibited by catalase, hydroxyl radical scavengers and L-NMMA (respectively 59, +/- 30% and 68% inhibition). CONCLUSIONS: High concentrations of histamine stimulated the neutrophils to product ROS and free radicals via H1 receptors and the NADPH-oxidase pathway. [less ▲]

This seminar proposes a detailed overview of the basic management principles that are emerging when managing a SME and, more specifically, a family business. The importance of SMEs in the Belgian economy, the role of the entrepreneur as an indiividual, the role of the family within the firm and key problems emerging in the day-to-day management of the firm are successively discussed.

Abstract for the thematic stream « Disciplines & Instruments » The aim of my intervention concern the implication of a scientific instrument inside an industrial context of usage. The latter takes the form of various little laboratories situated in the countryside. More precisely, those laboratories are generally situated in the area surronding fields and have the objective to evaluate the weight and the content of saccharose of the sugar beets deliveries ; and this for contractual purposes. The beet testing laboratories constitute a social and technical mediator by which a mode of coordination is temporarly crafted between two groups of actors : the growers and the sugar manufactuers. The instruments of measurment, and more specifically the polariscope, which compose this technological system have the interesting particularities to be submited to the contradictory supervision of both parties. Instead of just being a private place for secret industrial practices, the beet testing laboratory is widely open to public scrutiny. The perpetual negociations that take place inside the laboratories are done according to the « correct » application of a chemical protocol. In that respect, modes of visualisation are produced in order to give form to general values like efficacity, soundness or equity inside concrete procedures. The contradictory control that make the testing of sugar beets operational is conceived here as a dynamic pattern through which the reality of both a natural resource and the commited economical actors, is produced. Measurement as form of coordination is one of the central subjects in the field of the sociology of metrological practices. I will treat some aspects of industrial practices inside those beet testing laboratories in the light of the many ethnographical works done about scientific laboratories. [less ▲]

Respiratory disease is the principal cause of loss of young cattle worldwide. The syndrome arises from a number of factors, including Chose involving the animal, e.g., age, general condition and immune statue; ifs environment, e.g., changes in food, temperature and humidity that lead to stress; and the presence of infections agents, e.g., bacteria, viruses and mycoplasmas. The syndrome, in a method preferred by the author, can be classified into four grades: Grade 1, subclinical disease;Grade 2, compensated clinical disease (at this stage, the inflammatriry reaction generated tends to lirait the impact of the disease on thi animal); Grade 3, noncompensated clinical disease (at this stage, the inflamniattxy reaction is excessive and must be controlled); and Grade 4, irrevertibk clinical disease (which threatens the animal's survival). The increase in frequency and economic impact of bovine respiratory disease complex can be correlated with the escalating industrialisation of cattle production. In intensive operations, commingling of animale from multiple sources, exposure to many organisme, stress and management practicgs are all factors that can lead to disease. - The predisposition of cattle, especially beef calves, to respiratory problems is related to their lack of functional pulmonary hardiness. Selection of breeds that demonstrate adequate pulmonary function and sufficient ventilatory reserve may help in the control of the bovine respiratory disease complex, but this approach is difficult to implement and slow to produce results. Prophylactic measures, including vaccination programmes and modifying management practices to reduce stress, also have a place in preventing the bovine respiratory disease complex. Unfortunately, these measures are not always easy to put into operation and cannot completely eradicate the problem. Therapeutic strategies to minimise the economic impact of the syndrome include use of appropriate antibacterial therapy, modulation of the pulmonary inflammatory reaction and correction of mechanical disorders.
