The perception of climate change has become an exiting new field of research explored in recent years. This is a response from the international scientific community to the conclusions of the 4th report of the Intergovernmental Panel on Climate Change which had underlined serious deficiencies in this field, particularly in West Africa where population is largely dependent of rain-fed agriculture. Yet, a global survey of the literature since 2000 shows that most references on this topic were published over the last five years. [...] [less ▲]

Background: Previous data from the literature reported blunted perception of airway obstruction in severe asthmatics with near fatal asthma. Approximately 25% of patients with asthma are current smokers. Aim: To determine whether there is an alteration in perception of airway obstruction during a non specific provocative challenge with methacholine in mild controlled asthmatics who smoke. Methods: Enrolled in this study were 50 subjects, including 26 mild asthmatics and 24 healthy subjects, all of them current smokers. The first objective was the sensitivity of airway obstruction calculated by the regression slope linking the change in the visual analogic scale (VAS) assessed by the patient and the fall in FEV1 during a methacholine challenge. Results: Asthmatics who smoke had a blunted perception of airway obstruction during the bronchial challenge significantly different from that seen in healthy smokers (p = 0.03). This impaired dyspnea perception was inversely related to baseline VAS (r = -0.29, p<0.05) and positively related to baseline FEV1 (r = 0.35, p<0.05). Perception of airway obstruction was not correlated with age, sex, atopy or with airway inflammation features such as exhaled NO or sputum eosinophils. Conclusion: Mild asthmatics who smoke display reduced dyspnea perception during a nonspecific provocative challenge with methacholine. This altered perception of airway obstruction does not relate to airway inflammation. (C) 2007 Elsevier Ltd. All rights reserved. [less ▲]

This chapter tries to give a short overview of the main currents in contemporary theories of emotional expression. First, we attempt to draw a brief outline of how emotions are defined as compared to other affective states. Second, we try to give a short picture of the different views concerning the relationship between emotional expressions and experienced emotions, as well as the role of those expressions in human interactions. Third, the vocal and facial modes of emotion expressions are detailed. Fourth, we focus on how emotional expressions can be affected by different diseases, such as Parkinson’s disease, Steinert’s disease, and Moebius syndrome, at the vocal and the facial level. The impact of these impairments is considered in the light of the conclusions about the function of emotional expressions in society today. We conclude with a reflection about the therapy possibilities in reeducation of impaired emotional expressions. [less ▲]

BACKGROUND: Physician's perception of quality of life of patients with cancer is unclear. No reports have evaluated its influence on patient management. METHODS: Five hundred otolaryngologists completed a questionnaire regarding the quality of life of patients with head and neck cancer. RESULTS: Seventy-eight percent of responders thought that quality of life must be considered when choosing treatment, even if this meant decreased survival. Seventy-five percent thought it justified to withhold curative treatment if this would lead to impaired quality of life. Pain and breathing were the most important symptoms to consider. The perception was worse for physicians practicing in Latin culture, working in private practice, or with no personal acquaintance with a head and neck cancer victim and was better after radiotherapy than after surgery and chemotherapy. CONCLUSION: Quality of life is important for physicians and is considered as essential as survival by many physicians. The perception of patient's quality of life influences the treatment choice.

When listening to operatic singers performances, our perception of vocal pitch accuracy is influenced by several acoustical parameters such as the fluctuation of the fundamental frequency (i.e vibrato). In the case of occasional singers, produced pitch is likewise not constant, but the fluctuations in such cases tend not to involve vibrato but to instead involve “scoops” at the beginning and ends of tone, as well as other forms of instability. However, little is known about the fluctuations that characterize occasional singers (including poor-pitch singers) and to what degree these fluctuations influence perception of pitch accuracy. We report results of ongoing research designed to address these issues. First, we describe a descriptive model used to identify perturbations of F0 in occasional singers that differ between accurate and poor-pitch singers. Next, we report results of recent experiments that explore the influence of the pitch fluctuations described by the model on the perception of pitch accuracy. [less ▲]

BACKGROUND: Patients in a minimally conscious state (MCS) show restricted self or environment awareness but are unable to communicate consistently and reliably. Therefore, better understanding of cerebral noxious processing in these patients is of clinical, therapeutic, and ethical relevance. METHODS: We studied brain activation induced by bilateral electrical stimulation of the median nerve in five patients in MCS (aged 18-74 years) compared with 15 controls (19-64 years) and 15 patients (19-75 years) in a persistent vegetative state (PVS) with (15)O-radiolabelled water PET. By way of psychophysiological interaction analysis, we also investigated the functional connectivity of the primary somatosensory cortex (S1) in patients and controls. Patients in MCS were scanned 57 (SD 33) days after admission, and patients in PVS 36 (9) days after admission. Stimulation intensities were 8.6 (SD 6.7) mA in patients in MCS, 7.4 (5.9) mA in controls, and 14.2 (8.7) mA in patients in PVS. Significant results were thresholded at p values of less than 0.05 and corrected for multiple comparisons. FINDINGS: In patients in MCS and in controls, noxious stimulation activated the thalamus, S1, and the secondary somatosensory or insular, frontoparietal, and anterior cingulate cortices (known as the pain matrix). No area was less activated in the patients in MCS than in the controls. All areas of the cortical pain matrix showed greater activation in patients in MCS than in those in PVS. Finally, in contrast with patients in PVS, those in MCS had preserved functional connectivity between S1 and a widespread cortical network that includes the frontoparietal associative cortices. INTERPRETATION: Cerebral correlates of pain processing are found in a similar network in controls and patients in MCS but are much more widespread than in patients in PVS. These findings might be objective evidence of a potential pain perception capacity in patients in MCS, which supports the idea that these patients need analgesic treatment. [less ▲]

Introduction The perception of time is usually considered from sequential time but there are not any semiological markers of the capacity to apprehend the duration of time. Hypothesis The “capacity to feel the passage of time” is determinable by “semiological markers” in everyday life. Method Elaboration of a parental questionnaire (Likert scale); 2 samples from 2:6 to 12 years: 827 in general population and 297 in transnosographic population with psychological therapy; logistic regression; percentiles curves. Results General population: perception of the passage of time is gradually acquired; full competence at 9 years. The apprehension of sequential time is quasi maximum at 4 years. Atypical population: perception of the passage of time delayed of 18 months; important difficulties remain at 13 years. The apprehension of sequential time is delayed; at 13 years it remains bad at percentile 95. No differences according to the sex. Presentation of a short questionnaire for assessment. [less ▲]

Aims: This single-case study assess the emotional expression in a patient affected with Steinert disease in order to better analyze the patient's therapeutical needs as well as widen our perspective on the therapeutical means in speech therapy. Methods: A neutral text was read by the patient and a comedian, with five different emotions (joy, anger, fear, sadness and neutral). A group of judges identified the emotions by categorical choice and graded their intensity on a 4-point scale. The samples included three modes: visual, audio and audio-visual. Results: Compared to the comedian, the patient’s expression of emotion is less well perceived in the visual mode (65%>51%, (p=0.009)). In the gradation of intensity, there is a better correlation for the comedian (0.583>0.325, p<0.001) than for the patient. Conclusion: The results suggests that the emotions expressed by the patient are less well identified, especially through the visual channel, which confirms the influence of the patient’s disease on the quality of his emotional expressions. In addition, the fact that the patient's expressions are less well transmitted through the facial channel leads the author to consider a therapy focused not only on vocal capacities but also on facial mimicry.

Dans le cadre de cette étude, nous avons voulu mesurer la perception sociale du risque relatif à l’exposition aux champs électromagnétiques. Notre objectif était d’identifier les modes de connaissances auxquels se référent des individus qui font face à un risque empreint d’un niveau élevé d’incertitude scientifique. Comment ce public, mobilisé autour d’une problématique complexe, acquiert-il un niveau d’expertise suffisant pour comprendre les enjeux multiples (sociaux, économiques, éthiques, politiques et environnementaux) d’une technologie sur la société et ses modes d’organisation ? Quelle vision a-t-il des acteurs politiques et subpolitiques (Beck, 2001) qui prennent part aux débats ? Quel niveau de confiance accorde-t-il à un monde politique qui, en cas de risque majeur, pourrait invoquer une démarche précautionneuse et récupérer une partie du pouvoir décisionnel qui semblait lui échapper (Brunet, Delvenne & Joris, 2007) ? En situation de haute incertitude scientifique, qui sont les experts ? Quelle relation entretiennent les différents stakeholders 1 avec les autorités publiques? Le risque électromagnétique constitue un exemple éclairant de nouveau risque technologique, qui suscite une mobilisation sociale particulière et met en évidence les défis technologiques, sociaux, éthiques et politiques que nos sociétés occidentales doivent affronter à l’aube du XXIe siècle.

The FRAX tool that calculates the 10-year probability of having a fracture has recently been validated for Belgium. Little is known about the perception and knowledge that GPs have about this tool in their daily practice. A survey has been conducted as part of a screening campaign for various diseases. The primary objective of the present study was to assess the perception and the knowledge of the FRAX tool by GPs. The secondary objective was to assess the impact of an information brochure about the FRAX tool on these outcomes. The survey was sent to a sample of 700 GPs after only half of them had received the information brochure. The survey results show that, out of the 193 doctors who responded to the survey, one-third know the FRAX tool but less than 20 % use it in their daily clinical practice. Among those who use it, the FRAX tool is largely seen as a complementary but not as an essential tool in the diagnosis or in the management of osteoporosis. It appears that the brochure could improve the knowledge of the FRAX tool but it would not be more efficient on its use in daily practice than the other sources of information. At present, the use of the FRAX tool in Belgium is limited but an information brochure could have a positive impact on the knowledge of the FRAX tool. [less ▲]

This research has for objective the investigation of the process of enculturation at a sick child affected by a neoplastic disease. To this end, this report analyzes at first, the culture through an ethnographical reading of its definition, its paradoxes and its anthropological axioms. This first part urges us to widen our considerations, and to study the various vectors by which the culture passes in transit but also specific cultural items. In the second part, we review medical clinical notions of neoplasm at the child. A rigorous analysis of main oncologic typologies, their treatments and side effects are presented. The third part brings the reader through a general medical anthropology which offers an understanding of the disease as a cultural experience. For purpose of illustrations, a concise cross-cultural reflection between Japan and the West is carried out. For these both populations, the epidemiological situation of childhood cancer is proposed at first to underline then cultural elements of difference and convergence. A reflection on clinical implications with which health practitioners could be confronted comes to conclude. [less ▲]
