    A new method for testing removability of polymers in hair sprays and setting lotions (1993)

    Notes: Removability by shampoo and water is one of the criteria to be met by polymers used in hair sprays or setting lotions. To obtain quantitative measures for removabilities, ample laboratory testing is required. Gravimetry is one method which serves this purpose, with the disadvantage of being very time-consuming and depending on the individual handling of the materials. The new method to be presented in this paper is based on conductivity measurements of polymer-coated electrodes in electrolyte solutions. The effect of polymer blending and the degree of neutralization on removability can be assessed readily. Several polymers commonly used in hair sprays or setting lotions and polymer mixtures were tested. Comparison of the results shows good correlation between the two methods. The new method is especially useful in screening experiments. Changes in polymer properties as a function of composition can be detected rapidly.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméElimination au lavage est l'un des critères que doivent posséder les polymères utilisés dans les laques capillaires et les lotions coiffantes. Pour obtenir des mesures quantitatives quant à ce critère, des tests approfondis sont nécessaires. La gravimétrie est une méthode qui permet d'atteindre cet objectif avec l'inconvénient d'être longue, fastidieuse et dépendant de la manière dont les individus manipulent les matériaux. La nouvelle méthode présentée dans cet article est basée sur les mesures de conductivité d'électrodes enduites de polymères dans des solutions d'électrolyte. Il est alors aisé d'analyser le degré de neutralisation et d'élimination des polymères. On a ainsi testé plusieurs polymères purs ou en mélange fréquemment utilisés dans les laques capillaires ou lotions coiffantes. La comparaison des résultats montre une bonne corrélation entre les deux méthodes. La nouvelle méthode est particulièrement utile dans les expériences de criblage. Les changements de propriétés des polymères peuvent être rapidement détectés.

    Notes: AlAg is produced in a supersonic molecular beam by laser vaporization of alloy samples in a pulsed nozzle cluster source. Electronic spectroscopy is studied with resonant two-photon photoionization. In addition to the two electronic excited states previously reported by Clements and Barrow, we have observed ten new states. Vibrational analyses are presented for each of these states, and rotational analyses are given for selected states. The number and characteristics of these excited states are compared to the predictions of recent ab initio calculations.

    La section du ligament intermétatarsien dans la maladie de Morton (1991)

    Topics: Medicine
    Description / Table of Contents: Summary The authors publish their results of 26 patients, in whom 29 sections of intermetatarsal ligaments were done because of a Morton's syndrome. The Morton's syndrome has to be considered as a tarsal tunnel syndrome where the intermetatarsal ligament is the element responsible for the compression. The resection of the neuroma is useful only in quite exceptional cases where, because of its size, the neuroma takes part in the compression. Overall, the results are satisfactory. A 10 points score was established, taking into account: the subjective opinion, the answer to the question: “would you undergo another operation?”, the quality of walking, the type of shoe, and, the delay in putting on shoes again after the operation. Only 2 out of 26 patients had a mark below 6.
    Notes: Résumé Les auteurs présentent leurs résultats à propos de 26 patients chez lesquels 29 interventions de section du ligament intermétatarsien ont été réalisées pour Maladie de Morton. Ce syndrome est à considérer comme étant un syndrome du canal tarsien où le ligament intermétatarsien joue le rôle d'agent comprimant. La résection du névrome n'est indiquée que dans les rares cas où, en raison d'une grosse taille, le névrome exercerait de par lui même une compression. Les résultats sont globalement satisfaisants. Un score sur 10 points a été mis au point, prenant en compte: le résultat subjectif- la réponse à la question “vous feriezvous réopérer?” - la qualité de la marche - le chaussage - le délai de remise des chaussures habituelles. Il n'y a que deux patients sur 26 dont le score est inférieur à 6 sur 10.

    Description / Table of Contents: Summary The authors present their 30 years of experience of arthroplasty in the surgical treatment of avascular necrosis of the hip in the young adult. They used, in chronological order, the Smith-Petersen cup, the Vernon Luck cup, the Luck-Gérard double cup, the Wagner cemented double cup and finally the current use of the uncemented SCL screw-in femoral stem with a bipolar cup. Although the failure rate was high, each of these techniques took a step forward in delaying the time of total hip replacement.
    Notes: Résumé L'expérience de 30 ans de traitement chirurgical par arthroplastie à l'Hôpital Stéphanie est présentée dans le traitement de l'ostéonécrose aseptique de la tête fémorale chez l'adulte jeune. Elle passe par l'utilisation des cupules de Smith-Petersen, cupule ajustée de Luck, cupule de Luck-Gérard, cupule céramique cimentée, finalement l'arthroplastie de surface type Wagner et enfin, l'utilisation actuellement de prothèse fémorale sans ciment vissée SCL avec une cupule biarticulaire mobile. Chacune de ces techniques tout en restant imparfaite, a permis un pas de plus avec souvent le bénéfice de retarder l'heure de la prothèse totale de hanche.

    Description / Table of Contents: Summary Adult degenerative lumbar scoliosis is a subject today with functional problems like low back and root pain. In the past only the most severe deformities were operated, because of the risk of the intervention and the post-operative complications. Surgical treatment by the posterior approach with the rotation of the convex rod, gives normal anatomy without neurological risk. The instrumentation is strong enough to allow standing without brace or cast. An obvious advantage of this instrumentation is that it allows one to operate on scoliosis without restrictions due to age..
    Notes: Résumé La scoliose lombaire dégénérative est un sujet d'actualité posant des problèmes fonctionnels à type de douleurs lombaires ou radiculaires. Par le passé, le traitement chirurgical n'était envisagé que dans des cas extrèmes en raison des risques et de la lourdeur de l'intervention. Le traitement par en arrière en un seul temps opératoire par rotation de la tige convexe restitue l'anatomie sans prendre de gros risque neurologiques. La solidité de l'ostéosynthèse permet un lever rapide sans contention externe. Les avantages de la technique autorisent le traitement des patients souffrant de leur scoliose sans que l'âge ne soit un frein à l'indication.

    Description / Table of Contents: Résumé Le traitement orthopédique des scolioses a évolué de façon spectaculaire à partir des années 60 avec l'apparition des plâtres collés, du cadre de Cotrel et des corsets lyonnais en plexidur. Jadis “opprobre de l'orthopédie”, la scoliose idiopathique a vu progressivement son pronostic s'éclairer, au prix cependant d'un traitement contraignant et de longue durée. Il faut cependant savoir moduler le traitement en fonction de plusieurs paramètres : l'importance de la scoliose, la localisation de la courbure, l'âge osseux, l'âge d'état civil. Le cas idéal pour le traitement orthopédique est celui d'une scoliose lombaire ou thoraco-lombaire avec un test de RISSER initial inférieur à 2. Pour les courbures thoraciques, le traitement orthopédique n'est à poursuivre que si le gain angulaire reste supérieur à 30 % au long du traitement, sinon, il vaut mieux cesser le traitement orthopédique et indiquer la chirurgie.
    Notes: Summary The conservative treatment of scolioses has evolved in a spectacular way from the 60's onwards with the birth of glued plasters, the Cotrel frame and the lyonnais braces in plexidur. In the past “the disgrace of orthopaedics”, idiopathic scoliosis progressively saw its prognosis brighten up, at the cost nevertheless of a constraining and lengthy treatment. However, the treatment must be varied depending on several parameters: the importance of the scoliosis, the localization of the curvature, the bone age, the chronological age. The ideal case for the conservative treatment is that of a lumbar or thoracolumbar scoliosis with an initial Risser test inferior to 2. For thoracic curvatures, the conservative treatment is continued only if the angular gain remains superior to 30% during treatment, otherwise, it is better to stop the conservative treatment and recommend the surgery.
