Reduction of salivary flow with botulinum toxin: Extended report on 33 patients with drooling, salivary fistulas, and sialadenitis
No full textObjectives/Hypothesis. The aim of the study was the evaluation of the clinical data of 33 patients who had had drooling attributable to various diseases, salivary fistulas, and sialadenitis and had been treated with injection of botulinum toxin type A (Botox). A controlled follow-up study documenting efficiency, possible side effects, and duration of the effect of treatment was also performed. Study Design: Retrospective clinical evaluation. Methods. Thirty-three patients with drooling attributable to head and neck carcinoma, neurodegenerative diseases, stroke, or idiopathic hypersalivation or with salivary fistula or chronic sialadenitis received injections of 20 to 65 U botulinum toxin type A into salivary glands under sonographic control. The entire salivary flow rate and the output per minute of the salivary analytes thiocyanate, total protein, alpha-amylase, acid phosphatase, kallikrein, and immunoglobulin A were measured at various times before and after injection. The patients were examined with regard to severity of their symptoms, including sonographic control investigation of their cephalic salivary glands. Results: Twenty-six patients (79% of all patients) reported a distinct improvement of their symptoms after toxin injection. Seven patients noted a return of high salivation rates and requested a second injection after 4 to 7 months. Duration of toxin effect varied widely among individuals. In general, salivary flow rates and thiocyanate output dropped sharply within 1 week after injection and had increased again after a period of 12 to 16 weeks. Conversely, amylase outputs increased during this period, whereas the outputs of the other analytes remained roughly constant. Sonography did not reveal any major changes in salivary gland parenchyma, and side effects were not noted. Conclusion: Reduction of salivary flow in patients with drooling, salivary fistulas, or chronic sialadenitis by local injection of botulinum toxin type A into the salivary glands proved to be a dependable therapy for these disorders, as shown in the present extended report on 33 patients. Side effects were not observed. The effect of toxin application lasted for approximately 3 months. Based on their results, the authors recommend botulinum toxin injection as the therapy of choice in patients with the problem of drooling
Up-to-date report of botulinum toxin therapy in patients with drooling caused by different etiologies
No full textPurpose: In this study, we evaluated the clinical data for patients with drooling caused by various diseases, treated by injection of botulinum toxin A. We also present a controlled follow-tip study documenting efficiency, possible adverse events, and duration of the effect of treatment. Patients and Methods: Thirteen patients with drooling caused by head and neck carcinoma, neuro-degenerative diseases, or stroke received injections of 50 to 65 U botulinum toxin A (Botox; Allergan, Irvine, CA) in both submandibular and both parotid glands under sonographic control. We measured whole salivary flow rate and the salivary analytes of total protein, alpha-amylase, acid phosphatase, kallikrein, and immunoglobulin A at various times before and after injection. The patients were examined for severity of symptoms, including sonographic investigation of cephalic salivary glands. Results: All 13 patients reported a distinct improvement of their symptoms within 2 weeks after toxin injection. Three patients noted a return of high salivation rates after 12 weeks. Duration of toxin effect varied widely between individuals. In general, salivary flow rates dropped sharply within 1 week after injection but had risen again after 12 weeks. Conversely, analyte concentrations increased in the first stages of treatment and later decreased, returning to pretherapy levels. Sonography did not reveal any major changes of salivary gland parenchyma, and side effects were absent. Conclusions: Local injection of botulinum toxin A into the salivary glands proved to be a dependable therapy for drooling caused by various etiologies, as shown in 13 patients. Adverse events were not seen. The effect of toxin application lasted for about 3 months. To further clarify this aspect, long-term studies are under way.

Magnetospheric convection electric field dynamics and stormtime particle energization: Case study of the magnetic storm of 4 May 1998
No full textInternational audienceIt is shown that narrow channels of high electric field are an effective mechanism for injecting plasma into the inner magnetosphere. Analytical expressions for the electric field cannot produce these channels of intense plasma flow, and thus, result in less entry and adiabatic energization of the plasma sheet into near-Earth space. For the ions, omission of these channels leads to an underprediction of the strength of the stormtime ring current and therefore, an underestimation of the geoeffectiveness of the storm event. For the electrons, omission of these channels leads to the inability to create a seed population of 10-100 keV electrons deep in the inner magnetosphere. These electrons can eventually be accelerated into MeV radiation belt particles. To examine this, the 1-7 May 1998 magnetic storm is studied with a plasma transport model by using three different convection electric field models: Volland-Stern, Weimer, and AMIE. It is found that the AMIE model can produce particle fluxes that are several orders of magnitude higher in the L = 2 ? 4 range of the inner magnetosphere, even for a similar total cross-tail potential difference
The SF-36: a simple, effective measure of mobility disability for epidemiological studies
No full textBackgroundMobility disability is a major problem in older people. Numerous scales exist for the measurement of disability but often these do not permit comparisons between study groups. The physical functioning (PF) domain of the established and widely used Short Form-36 (SF-36) questionnaire asks about limitations on ten mobility activities.ObjectivesTo describe prevalence of mobility disability in an elderly population, investigate the validity of the SF-36 PF score as a measure of mobility disability, and to establish age and sex specific norms for the PF score.MethodsWe explored relationships between the SF-36 PF score and objectively measured physical performance variables among 349 men and 280 women, 59-72 years of age, who participated in the Hertfordshire Cohort Study (HCS). Normative data were derived from the Health Survey for England (HSE) 1996.Results32% of men and 46% of women had at least some limitation in PF scale items. Poor SF-36 PF scores (lowest fifth of the gender-specific distribution) were related to: lower grip strength; longer timed-up-and-go, 3m walk, and chair rises test times in men and women; and lower quadriceps peak torque in women but not men. HSE normative data showed that median PF scores declined with increasing age in men and women.ConclusionOur results are consistent with the SF-36 PF score being a valid measure of mobility disability in epidemiological studies. This approach might be a first step towards enabling simple comparisons of prevalence of mobility disability between different studies of older people. The SF-36 PF score could usefully complement existing detailed schemes for classification of disability and it now requires validation against them
12 – L’illusion picturale
No full text« Si, quand on fait un tableau, on suppose des spectateurs, tout est perdu. » Le livre de Michael Fried se donne pour premier dessein de comprendre ce paradoxe énoncé par Diderot dans une lettre à Sophie Volland du 18 juillet 1762. Pour ce faire, il lui faut identifier un certain nombre des traits spécifiques qui singularisent la peinture française après la mi-XVIIIe siècle. Le premier tient à la fréquence d’une représentation : celle de personnages absorbés dans une action, une méditation, u..
Ionogels, nouveaux matériaux pour l'immobilisation de complexes et particules métalliques (Applications )
No full textCette thèse décrit des matériaux ionogels composés d'un liquide ionique confiné dans une matrice de silice et leur utilisation en catalyse homogène et comme nanoréacteurs pour la croissance de nanoparticules métalliques. En effet, les liquides ioniques sont particulièrement intéressants dans de nombreux domaines : électrochimie, catalyse et biocatalyse, optique, stabilisation de particules Cependant, ces liquides ioniques peuvent posséder une viscosité assez élevée qui rend difficile leur agitation durant une réaction. Afin de contourner ce proble me, de nouvelles voies d'immobilisation du liquide ionique ont été développées. Parmi elles, une méthode est développée au laboratoire qui consiste à confiner le liquide ionique dans une matrice de silice par un procédé sol-gel. Ces ionogels, présentent l'avantage de combiner les propriétés du liquide ionique et du solide. L'influence de certains paramètres de synthèse (voie hydrolytique avec ou sans HCl, pseudo non-hydrolytique avec de l'acide formique, choix du liquide ionique ) sur la structure finale du matériau a été étudiée. Parallèlement, différents précurseurs de silice ont été testés dans le but de parvenir à une amélioration de leur tenue mécanique. Par ailleurs, l'intérêt des ionogels dopés par du palladium acétate pour la catalyse a été prouvé par les résultats obtenus dans le cadre de la réaction de Heck tandis que l'aspect de nanoréacteur a été exploré au travers de la synthèse in situ de nanoparticules de palladium, d'or et d'argent. A l'image de leurs propriétés structurales modulables à partir des paramètres de synthèse, les ionogels se révèlent être des matériaux ajustables à des applications multiples : électrolyte solide, immobilisation de catalyseur en liquide sans extraction de métal, nano-réacteurs pour la croissance de nanoparticules...This work describes ionogels, materials composed by an ionic liquid confined in a silica matrix and their uses in catalyse and in the growth of metals nanoparticles. Ionic liquid is very attractive in a large range of domains: electrochemistry, catalyse and biocatalyse, optic, particles stabilisation...However, these ionic liquids have a high viscosity which makes the stirring difficult. In order to avoid this problem, new ways to confine an ionic liquid were developed. Among them, a method was created at the lab: the ionogels. They combine ionic liquid and solid properties. The influence of some synthetic parameters (sol-gel process conditions, ionic liquid choice...) on the final structure of the material was studied. Moreover, different silica precursors were tested to have a mechanical amelioration. Besides, the interest of acetate palladium doped ionogels in catalyse was proved by the results of the Heck reaction experiments whereas the nanoreactors applications was explored with the in situ synthesis of palladium, gold and silver nanoparticlesMONTPELLIER-BU Sciences (341722106) / SudocSudocFranceF
