Stress reducing strategies are useful in patients undergoing surgery. Hypnosis is also known to alleviate acute and chronic pain. We therefore compared the effectiveness of these two psychological approaches for reducing perioperative discomfort during conscious sedation for plastic surgery. Sixty patients scheduled for elective plastic surgery under local anesthesia and intravenous sedation (midazolam and alfentanil upon request) were included in the study after providing informed consent. They were randomly allocated to either stress reducing strategies (control: CONT) or hypnosis (HYP) during the entire surgical procedure. Both techniques were performed by the same anesthesiologist (MEF). Patient behavior was noted during surgery by a psychologist, the patient noted anxiety, pain, perceived control before, during and after surgery, and postoperative nausea and vomiting (PONV). Patient satisfaction and surgical conditions were also recorded. Peri- and postoperative anxiety and pain were significantly lower in the HYP group. This reduction in anxiety and pain were achieved despite a significant reduction in intraoperative requirements for midazolam and alfentanil in the HYP group (alfentanil: 8.7 +/- 0.9 microg kg(-1)/h(-1) vs. 19.4 +/- 2 microg kg(-1)/h(-1), P < 0.001; midazolam: 0.04 +/- 0.003 mg kg(-1)/h(-1) vs. 0.09 +/- 0.01 mg kg(-1)/h(-1), P < 0.001). Patients in the HYP group reported an impression of more intraoperative control than those in the CONT group (P < 0.01). PONV were significantly reduced in the HYP group (6.5% vs. 30.8%, P < 0.001). Surgical conditions were better in the HYP group. Less signs of patient discomfort and pain were observed by the psychologist in the HYP group (P < 0.001). Vital signs were significantly more stable in the HYP group. Patient satisfaction score was significantly higher in the HYP group (P < 0.004). This study suggests that hypnosis provides better perioperative pain and anxiety relief, allows for significant reductions in alfentanil and midazolam requirements, and improves patient satisfaction and surgical conditions as compared with conventional stress reducing strategies support in patients receiving conscious sedation for plastic surgery.

Model liquid-crystalline ionomers have been synthesized, which consist of low molecular weight (700-49000) linear ω- and α,ω-sodium sulfonate- and carboxylato-poly(styrenes or isoprenes) selectively end-capped at one or both end(s) with an ionic mesogenic group. These compounds are referred to as liquid-crystalline halato(semi)telechelic polymers [LC H(S)TPs] A combination of small-angle X-ray scattering and small-angle neutron scattering studies on these LC H(S)TPs clearly shows the usual ionic peak related to interparticle interference between the ionic aggregates and a peak which can be related to the organization of a smectic mesophase. This mesogenic peak is generally masked by the foot of the broad ionic peak. The ionic peak Bragg spacing is much larger in the LC H(S)TP than in the H(S)TP precursor; This increased interaggregate distance results from the hindrance due to the mesogenic organization and from the restricted mobility experienced by the chains closely attached to the mesogen layers. As a rule, the lower the glass transition temperature of the polymeric matrix, the better the definition of the ionic peak, The ionic peak is well defined as long as the temperature is lower than the temperature of transition from solid to smectic phase (32.3 K). At higher temperatures, the ionic peak intensity decreases with increasing temperature. [less ▲]

The 1st September 1995, the belgian Federal Ministry of Agriculture set up a compulsory control of the sprayers used. All the devices, except for some ofthem, are subjected to a compulsory periodic checking. The practical organsization of the control as well as the test procedure are a bit different from the ones of other European countries. They have been chosen on the basis of educational criteria rather than repressive ones. After 20 months of control, the result is encouraging. More than 13 000 sprayers have already been controlled. Less than 5 % of the devices are rejected after a first control. The condition of working sprayers has been improved. At last, this action has made the controlled owner conscious of the problems related to the spreading og agrochemicals. [less ▲]

L'enquête qui a servi de base au rapport reprend après six ans la dynamique d'enquêtes récurrentes initiée entre 1988 et 1991. Il s'agissait de voir comment avaient évolué les sentiments d'appartenance des wallons mais aussi la légitimité de toute une série d'institutions publiques, ainsi que l'évaluation des principales politiques wallonnes, une fois l'institution "région wallonne" établie dans le paysage. Mais l'enquête se ressent du contexte : elle a été réalisée peu de temps après la marche blanche de 1996, qui fut aussi une année de lourdes fermetures d'entreprises. L'ensemble des opinions exprimées s'en ressent fortement. [less ▲]

As shown in animal studies, 5HT1B/D agonists can inhibit activity in the trigeminal nucleus caudalis, which may be advantageous for their antimigraine effect. To demonstrate a possible central nervous system (CNS) action of these compounds in man we studied their effect on the intensity dependence of the cortical auditory evoked potentials (IDAPs), thought to be inversely related to central serotonergic transmission. An amplitude/stimulus intensity function (ASF) slope was computed in healthy volunteers and migraine patients between attacks before and 2 h after oral 311C90 (zolmitriptan "Zomig") 10 mg (n=14), 311C90 5 mg (n=7), sumatriptan 100 mg (n=14), dexfenfluramine 15 mg (n=4), lorazepam 1.25 mg (n=4) and placebo (n=14). 311C90 10 mg and, to a lesser degree, 5 mg significantly increased the mean ASF slope (p=0.007 and 0.05 vs placebo). There was a significant positive correlation between plasma levels of 311C90 and ASF slope changes. Sumatriptan and lorazepam had little effect, but dexfenfluramine produced a significant ASF slope decrease. 311C90 is able to modify a CNS activity that is modulated by serotonin, i.e. the IDAP. This effect is probably the consequence of its superior lipophilicity compared to sumatriptan and of activation of prejunctional 5HT1B/D autoreceptors, which lowers central serotonin release and thus the preactivation level of sensory cortices.
