La réforme de la politique agricole commune s'oriente vers une diminution du soutien des revenus agricoles par les politiques des prix et des marchés. Des mesures d'aides directes modulées et plus ciblées seront mises en place afin de compenser la baisse du revenu des agriculteurs. En outre, la politique agricole ne peut être dissociée de la politique régionale qui vise la cohésion économique et sociale entre les diverses régions de la Communauté. Le développement des zones rurales représente un de ses objectifs prioritaires. Les dispositions de soutien direct des revenus peuvent donc jouer un rôle en accordant une aide - sous la forme d'un soutien du revenu minimum - à certaines catégories d'agriculteurs opérant dans des régions défavorisées ou confrontés à une situation difficile. L'une des principales difficultés dans l'élaboration d'une politique régionale de soutien direct au revenu des agriculteurs réside dans la détermination des zones pouvant être prises en considération. L'objectif de la recherche menée est précisément de proposer des critères susceptibles d'orienter l'éligibilité des zones rurales dans le cadre d'actions portant sur la politique des structures et d'analyser les effets des choix opérés pour la Belgique. Dans un premier temps, les auteurs examinent les aides directes octroyées aux régions agricoles défavorisées en Belgique ainsi que les critères pris en compte pour déterminer ces zones. Ensuite, ils présentent les principes et les résultats globaux d'une méthode basée sur la classification numérique et visant à déterminer les zones concernées par le soutien direct des revenus.

Although pain after laparoscopic cholecystectomy is less intense than after open cholecystectomy, some patients still experience considerable discomfort. Furthermore, the characteristics of postlaparoscopy pain differ considerably from those seen after laparotomy. Therefore, we investigated the time course of different pain components after laparoscopic cholecystectomy and the effects of intraperitoneal bupivacaine on these different components. Forty ASA physical status grade I-II patients were randomly assigned to receive either 80 mL of bupivacaine 0.125% with epinephrine 1/200,000 (n = 20) or the same volume of saline (n = 20) instilled under the right hemidiaphragm at the end of surgery. Intensity of total pain, visceral pain, parietal pain, and shoulder pain was assessed 1, 2, 4, 6, 8, 24, and 48 h after surgery. Analgesic consumption was also recorded. Patient data were similar in the two groups. In the saline group, visceral pain was significantly more intense than parietal pain at each time point; visceral and parietal pain were greater than shoulder pain during the first 8 h postoperatively. Intraperitoneal bupivacaine did not significantly affect any of the different components of postoperative pain. Analgesic consumption was similar in the two groups. This study demonstrates that visceral pain accounts for most of the pain experienced after laparoscopic cholecystectomy. Intraperitoneal bupivacaine is not effective for treating any type of pain after laparoscopic cholecystectomy. [less ▲]

The neural mechanisms underlying the antinociceptive effects of hypnosis still remain unclear. Using a parametric single-trial thulium-YAG laser fMRI paradigm, we assessed changes in brain activation and connectivity related to the hypnotic state as compared to normal wakefulness in 13 healthy volunteers. Behaviorally, a difference in subjective ratings was found between normal wakefulness and hypnotic state for both non-painful and painful intensity-matched stimuli applied to the left hand. In normal wakefulness, non-painful range stimuli activated brainstem, contralateral primary somatosensory (S1) and bilateral insular cortices. Painful stimuli activated additional areas encompassing thalamus, bilateral striatum, anterior cingulate (ACC), premotor and dorsolateral prefrontal cortices. In hypnosis, intensity-matched stimuli in both the non-painful and painful range failed to elicit any cerebral activation. The interaction analysis identified that contralateral thalamus, bilateral striatum and ACC activated more in normal wakefulness compared to hypnosis during painful versus non-painful stimulation. Finally, we demonstrated hypnosis-related increases in functional connectivity between S1 and distant anterior insular and prefrontal cortices, possibly reflecting top-down modulation. [less ▲]

Vagus nerve stimulation (VNS), already used as a treatment for refractory epilepsy, has also been assessed for its analgesic effect. Numerous studies report that electrical stimulation of vagal afferents inhibits spinal nociceptive reflexes and transmission. However results are partly contradictory, showing that the VNS effects depend on the stimulation parameters. Clinical data have been collected from VNS-implanted epileptic patients in whom pain thresolds were measured and the VNS effect on co-existing headaches was assessed. In addition, in 2 pilot studies of a few patients, VNS was used to treat resistant chronic headaches and migraines. Taken together these clinical studies tend to confirm the analgesic effect of VNS and to suggest its potential utility in chronic headache patients. In order to better define the nature of neuronal and behavioural changes induced by VNS with devices used in humans and to determine the most adequate stimulation stimulation protocols, we have used a commercially available stimulator (NCP-Cyberonics(R)) for prolonged VNS in rats. Our results show a clear antinociceptive effect of VNS in models of acute or inflammatory pain with different stimulation protocols including the one used in epileptic patients. Using immunocytochemical methods, we find that activity changes in spinal trigeminal nucleus neurons could underlie at least part of the VNS-induced analgesia. [less ▲]

Background: The assessment of pain and nociception in non-communicative patients with disorders of consciousness (DOC) is a real challenge for clinicians. It is, therefore, important to develop sensitive standardized tools usable at the bedside. Objectives: This review aims to provide an overview of the current knowledge about pain processing and assessment in patients with DOC. Methods: A search was performed on PubMed using MeSH terms including vegetative state, unresponsive wakefulness syndrome, minimally conscious state, consciousness disorders, pain, nociception, neuroimaging and pain assessment. Results: Neuroimaging studies investigating pain processing in patients with DOC and their implication for clinicians are reviewed. Current works on the development of standardized and sensitive tools for assessing nociception are described. Conclusion: The suggested pain perception capacity highlighted by neuroimaging studies in patients in a MCS and in some patients in a VS/UWS supports the idea that these patients need analgesic treatment and monitoring. The first tool which has been developed to assess nociception and pain in patients with DOC is the NCS. Its revised version represents a rapid, standardized and sensitive scale which can be easily implemented in a clinical setting. Complementary pain assessments are also under validation in order to offer more options to clinicians. [less ▲]

Pain, suffering and positive emotions in patients in vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious states (MCS) pose clinical and ethical challenges. Clinically, we evaluate behavioural responses after painful stimulation and also emotionally-contingent behaviours (e.g., smiling). Using stimuli with emotional valence, neuroimaging and electrophysiology technologies can detect subclinical remnants of preserved capacities for pain which might influence decisions about treatment limitation. To date, no data exist as to how healthcare providers think about end-of-life options (e.g., withdrawal of artificial nutrition and hydration) in the presence or absence of pain in non-communicative patients. Here, we aimed to better clarify this issue by re-analyzing previously published data on pain perception (Prog Brain Res 2009 177, 329–38) and end-of-life decisions (J Neurol 2010 258, 1058–65) in patients with disorders of consciousness. In a sample of 2259 European healthcare professionals we found that, for VS/UWS more respondents agreed with treatment withdrawal when they considered that VS/UWS patients did not feel pain (77%) as compared to those who thought VS/UWS did feel pain (59%). This interaction was influenced by religiosity and professional background. For MCS, end-of-life attitudes were not influenced by opinions on pain perception. Within a contemporary ethical context we discuss (1) the evolving scientific understandings of pain perception and their relationship to existing clinical and ethical guidelines; (2) the discrepancies of attitudes within (and between) healthcare providers and their consequences for treatment approaches, and (3) the implicit but complex relationship between pain perception and attitudes toward life-sustaining treatments.

Six patients with the syndrome of "painful legs and moving toes" were studied. Although clinical differences were nonspecific, the EMG disclosed two subgroups: one with a simple, erratic pattern of spontaneous activities in foot and leg muscles, and the other with a complex alternating pattern in antagonistic muscles. In the first group, the physiopathologic mechanism is thought to act in the periphery: in the lumbar roots when local anesthesia of the posterior tibial nerve suppresses spontaneous discharges, or in the nerve trunk when it is ineffective. In the second group, the symptomatology may be generated centrally, implying a more general disturbance of sensorimotor control. [less ▲]

Paints, at the coating meaning, are known since a long time. Typically, paint is a dispersion of one or more powders (pigments and fillers) in a macromolecular substance ("resin"), called film-forming material, diluted in solvents. Pigments are solid particles, used to give opacity and/or color. Today almost all pigments have a synthetic origin. The fillers are often natural compounds. Unlike pigments, fillers have low opacity and are colorless. These very cheap products achieve the required solid content under satisfactory economic conditions. Resins used in paints have the property of forming a continuous solid (hard or flexible) film under specific conditions. They are often called “resins”. They can be solid or liquid at room temperature. The solvents are used to control the viscosity of the paint in order to facilitate its production and application. The solvents used are volatile compounds. Additives are minor compounds (a few percent), whose function is to either promote or prevent some developments of the product. For example, surfactants improve the homogeneity of the dispersion. Some additives protect the film against mold or ultraviolet radiation, or against the formation of free radicals under the action of sunlight. Since the end of the 18th century most of those paints are petroleum-based. But the near disappearance of the petroleum causes a renewed interest in bio-based preparations. In this communication, we present an overview of bio-based alternatives. [less ▲]
