    Beschreibung / Inhaltsverzeichnis: Résumé Nous avons étudié rétrospectivement 19 patients opérés pour une hydaditose hépatique s'étendant soit vers le diaphragme, soit vers le thorax par extension transdiaphragmatique (TD) dans une série de 444 patients ayant été opérés. Dans tous les cas de TD, le diagnostic a été confirmé par l'échographie, la tomodensitométrie ou la résonance magnétique nucléaire. Nous proposons une nouvelle classification (grades 1 à 5), basée sur le degré de TD. Avant 1984, une thoracophrénolaparotomie a été la voie d'abord préférée (9 cas) puis on a utilisé la voie souscostale droite. Seulement quatre patients ont nécessité une résection pulmonaire atypique. Chez 13 patients, on a réparé immédiatement le diaphragme et tous les kystes hydatiques hépatiques (n=24) ont été traités par une périkystectomie soit totale (16 cas) soit partielle (8 cas). Il n'y a eu aucun décès et la complication la plus grave observée a été une fistule biliaire et bilio-bronchique. Nous recommandons la périkystectomie totale ou presque totale par une incision sous-costale droite prolongée chez ces patients.
    Kurzfassung: Resumen Hemos realizado un estudio retrospectivo de 19 pacientes operados por enfermedad hidatídica hepática con extensión diafragmática o transdiafragmática (E-TD) al toráx, dentro de un total de 44 pacientes sometidos a cirugía por enfermedad hidatídica del hígado. En la totalidad de los casos la extensión E-TD fue confirmada por ultrasonografía, TAC o resonancia magnética. Proponemos una nueva clasificación (grados 1 a 5) basada en el grado de desarrollo de la extensión E-TD. Con anterioridad a 1984, se hizo la exposición mediante toracofrenolaparotomía (9 casos) y más tarde por incisión subcostal derecha. Sólo 4 pacientes requirieron una resección pulmonar atípica. En 13 casos el diafragma fue reparado y todos los 24 quistes hepáticos fueron tratados mediante cistopericistectomía total (16 casos) o parcial (8 casos). No se registró mortalidad operatoria y la morbilidad más seria consistió en una fístula biliar y una broncobiliar. Para el tratamiento de este tipo de pacientes nosotros recomendamos una incisión subcostal derecha y una cistopericistectomía total o casi total como la técnica quirúrgica de primera escogencia.
    Notizen: Abstract We performed a retrospective study of 19 patients who had been operated on for hepatic hydatid disease with diaphragmatic or transdiaphragmatic (D-TD) thoracic involvement chosen from a total of 444 patients who underwent operations for hepatic hydatid disease. In all cases D-TD involvement was confirmed by ultrasonography, CT, or MRI scan. We propose a new classification (grades 1–5) based on the degree of development of D-TD involvement. Before 1984 exposure was obtained by thoracophrenolaparotomy (nine cases) and later by right subcostal incision. Only four patients required atypical pulmonary resection. In 13 cases the diaphragm was repaired, and all 24 hepatic cysts were treated with total (16 cases) or partial (8 cases) cystopericystectomy. There was no operative mortality, and the most serious morbidity consisted of a biliary fistula and a biliobronchial fistula. For treatment of these patients we recommended right subcostal incision and total or near-total cystopericystectomy as a first choice of surgical technique.

    Notizen: Vinylchloride-vinylthiocresol and vinylchloride-vinylthionaphthol copolymers of various compositions were prepared by the substitution reaction of PVC with sodium thiocresol and sodium thionaphthol, respectively, in different solvents and at different temperatures. The variation of the glass transition temperature of these copolymers with chemical com-position does not follow the Flory-Fox equation, but is found to depend on the solvent and the temperature at which the copolymer is obtained. The comonomer sequence distribution and stereosequence content of the above copolymers, and those of vinylchloride-vinyl-thiobenzene copolymer, were determined by 1H- and 13C-NMR spectroscopy. The depen-dence of comonomer distribution and stereoregularity content with chemical composition for the three series of copolymers, prepared in different solvents and temperatures, are similar. The Tg deviations for the three series of copolymers were attributed to the con-tribution of physical characteristics of the PVC structure, originating from polymer-solvent interactions. © 1995 John Wiley & Sons, Inc.

    Notizen: Batch emulsion polymerization was used in order to obtain latexes from a mixture of butyl acrylate (ca. 90% mole), and a hydrophobic crosslinkable functional monomer called N-isobutoxymethyl acrylamide (ca. 10% mole). Films were then cast from these latexes, and their thermomechanical properties were studied before and after a heat treatment intended to provoke crosslinking of the functional groups. The differential thermal analysis and the dynamic mechanical analysis of the film samples proved that the functional monomer copolymerized with butyl acrylate; the dynamic mechanical analysis revealed also that crosslinking took place after the heat treatment. Different kinds of high strain experiments (among which there were stress relaxation tests) were carried out in a tensile testing machine Important differences were thus shown to appear between the “as-dried” and “annealed” samples. In the case of stress relaxation experiments, simple mechanical models were used in order to fit the experimental data, both during the stretching experiment and the stress relaxation following it. The analysis of the high-strain experiments and their simulation led to the conclusion that the films contained high molecular weight polymers having a broad molecular weight distribution, and that their crosslinking enhanced the entropic elastic behavior, even though a viscoelastic, large relaxation time contribution was kept; the hypothesis of its coming from a trapped-entanglement effect was proposed.

    Notizen: A two-stage emulsion polymerization procedure was used in order to obtain core-shell polymer particles having a core of polystyrene (PS), covered by a shell of either pure poly(butyl acrylate) (PBA) or a methacrylic acid-functionalized PBA. Films were then cast from these latexes, and their properties were studied without further treatments (“as-dried” films), as well as after a 3 hr heat treatment intended to provoke the coalescence of PS domains (“annealed” films). “As-dried” and “annealed” film samples were studied by dynamic mechanical analysis (DMA), scanning electron microscopy (SEM) and small angle neutron scattering (SANS). DMA and SEM results, as described in previous works, showed that for unfunctionalized films, the percolated PS domains coalesced under the annealing treatment, while for the functionalized films, they did not. On the other hand, SANS results presented here showed that even in the case of functionalized films, the presence of coalescence could be detected. It was concluded that while DMA and SEM reveal large-scale modifications provoked by the heat treatment, SANS is capable of detecting very smallscale changes which do not have a direct effect on the bulk physical properties of the samples.

    Notizen: 2-Mercaptobenzyl alcohol and 4-mercaptobenzyl alcohol were synthesized in good yields starting form thiosalicylic acid and p-toluenesulfonic acid, respectively. Poly(vinyl chloride) (PVC) reacts selectively with the thiol group of these bifunctional compounds leading to modified PVC with free hydroxy groups. In a second step the polymer chains can be partially crosslinked by reaction with hexamethylene diisocyanate. According to the degree of PVC modification, the network density of the resulting elastomers is freely adjustable.
