Cricotracheal resection for adult and pediatric subglottic stenoses: Similarities and differences

Since the mid-1970s thoracic surgeons have used cricotracheal resection (CTR) in the adult population. Similar positive results have from then on been reported by different investigators using this technique. In contrast, otolaryngologists have typically used an anterior midline approach to the larynx and trachea for their laryngotracheal reconstructions (LTRs), both in adults and children. The fear of injury to the recurrent laryngeal nerve (RLN), the risk of a dehiscence of the anastomosis, and the interference with normal growth of the larynx in the pediatric age group were the main reasons put forward for not using a CTR for the cure of subglottic stenosis. In this article, we describe the similarities and differences in CTRs performed for adult and pediatric cases. The high rate (>90%) of success for severe pediatric SGS using CTR compares most favorably with LTR, which is still used in most otolaryngology departments. The reasons lie in the full resection of the stenosis and the restoration of a steady cartilaginous framework of the larynx and trachea with full mucosal lining on both sides of the anastomosis. Furthermore, CTR can be associated with a Rethi procedure for the cure of combined posterior glottic and subglottic stenoses. Good results from series of two different centers suggest that CTR will become the treatment of choice for pediatric severe SGS, as is presently the case in the adult population.

Traumatic recurrent anterior dislocation of the shoulder: two- to four-year follow-up of an anatomic open procedure.

The purpose of this study was to evaluate the results of an anatomic open stabilization procedure. Twenty-three consecutive patients with traumatic, recurrent, anterior glenohumeral instability were managed with a modified open procedure. All had a Bankart lesion. A standardized, true anatomic capsulolabral reconstruction was performed with suture anchors. Two patients were lost to follow-up, and twenty-one were evaluated after 36 months [range, 24-49 months] by an independent observer. Shoulder stability and function were the principal outcome measures. None of the patients had subsequent dislocations. All returned to full working capacity, and 19 reached their previous level of sport activities. The mean loss in active abduction and flexion was 1 degrees, in internal rotation, one vertebral level, and in external rotation, 7 degrees (arm at 90 degrees of abduction). Two patients had a positive anterior apprehension test. No sign of shoulder osteoarthritis was observed. The open anatomic capsulolabral reconstruction provides excellent results and allows the restoration of stability with good function.

Role of HIV-1-specific CD4 T cells.

PURPOSE OF REVIEW: Most of the studies investigating antiviral immunity have predominantly focused on CD8 T cells. However, numerous recent studies have highlighted the importance of HIV-1-specific CD4 T cells in the antiviral immune response, and have also revealed the high level of complexity and heterogeneity of the virus-specific CD4 T-cell responses. An understanding of the role of these key players in the antiviral immune response is of fundamental importance.RECENT FINDINGS: A comprehensive investigation of several features of virus-specific CD4 T-cell responses, including the magnitude, breadth, function and phenotype, has recently been performed. In particular, HIV-1-specific CD4 T-cell responses have been studied in different stages of HIV-1 infection, i.e. acute and chronic phase, under conditions of spontaneous (long-term non-progressors) or antiviral therapy-mediated control of virus replication or uncontrolled virus replication. Different phenotypical and functional patterns of HIV-1-specific CD4 T-cell responses were associated with different conditions of controlled versus uncontrolled virus replication, thus allowing the identification of signatures of protective immune responses. Robust and diverse virus-specific CD4 T-cell responses have been observed. These responses, however, were not predictive of nonprogressive versus progressive HIV-1-associated disease.SUMMARY: There is an urgent need to delineate the immune correlates of protective T-cell responses in order to develop novel immunological markers to evaluate the degree of immune restoration of antiviral therapy as well as the potential effectiveness of HIV vaccine-induced T-cell immune responses.

Aquest treball s’inclou dins la línia de recerca de la Secció de Conservació-Restauració delPatrimoni que es centra en l’estudi tècnic dels suports de fusta de frontals i retaules percaracteritzar-los i aportar noves informacions sobre els materials constitutius, els seussistemes de construcció i el seu origen. En aquest cas, l’estudi es centra en pintura sobretaula catalana del segle XII.La selecció de peces i l’acotació del tema van sorgir arrel d’un treball fi nal de màster (setembre2009) en el que ja es van estudiar els suports d’un conjunt de taules de fusta policromades dels segles XI, XIII i XIV custodiades al Museu Episcopal de Vic (MEV)...

La conservació del revers Criteris de restauració del suport de tela de la pintura catalana moderna com a testimoni històric i artístic

Cada quadre conté diferents tipus d’informació. El missatge estètic, materialitzat en la sevacapa pictòrica, és el que acostuma a ser objecte de valoració, crítica o simplement gaudi,però no és l’únic. Existeixen altres elements que poden donar-nos coneixement i que se situen al darrera d’aquest estrat pictòric. El suport de la pintura n’és un d’ells, i el revers, és la superfície d’aquesta matèria...

Una nova eina per a l’estudi del paper i les filigranes. Anàlisi i desenvolupament d’una base de dades per a l’estudi del paper i de les filigranes: font per a l’elaboració de la història del paper a Espanya

L’aspiració de trobar una eina que pugui ajudar a identifi car els papers atenent les sevescaracterístiques sorgeix a fi nal segle XVIII amb les primeres descripcions de les filigranespapereres i va prenent cos al segle XIX com a ciència auxiliar de la codicologia.Des de les últimes dècades del segle XX, les filigranes han anat adquirint un interès creixententre els restauradors de document gràfi c —com una eina més per a la presa de decisions i pera la valoració del procés de restauració— i entre els documentalistes, historiadors, museòlegsi bibliòfils —per a la datació i autenticació de les obres— i, fins i tot, en investigacionspolicials i jurídiques per aclarir algun fet delictiu. No obstant això, durant aquests 150 anys, l’estudi del paper a través de les filigranes papereres a Espanya no ha experimentat cap avenç significatiu pel que fa als mètodes i procediments seguits per a l’obtenció i gestió deles dades. En l’àmbit europeu, encara que a partir dels anys 90 sorgeixen noves propostesd’estudi, aquestes limiten la investigació a l’anàlisi de la filigrana sense assolir una visió global del plec sortit de la forma.

Assessing the pH and DP of canvasses with NIR spectroscopy

The canvas support in easel paintings is composed mainly of cellulose. One of the maindegradation paths of cellulose is acid-catalysed hydrolysis, which means that in an acidic environment (low pH), its degradation proceeds at a faster rate (Strlič et al., 2005).The main effect of acid-catalysed hydrolysis is the breaking up of the polymer chains,measured by the “Degree of Polymerisation” (DP). The lowering of the DP value impliesa lower mechanical strength of the textile (Scicolone, 1993), and thus this parameter canbe used to monitor degradation. Knowing these two parameters can, therefore, be veryinformative regarding the condition of the canvas support.

El deterioro del soporte de contrachapado: propuesta de restauración de 9 obras de Francesc Artigau

Francesc Artigau (Barcelona 1940) pintó en los años setenta una serie de obras al temple sobre contrachapado. De éstas, dos trípticos y un díptico estaban destinados a decorar un hotel en Masquefa (Lérida), pero fueron rechazados por su atrevimiento y sus colores, y quedaron en propiedad del agente intermediario, junto con otra obra de menor formato. Las nueve obras sufrieron después un grave proceso de deterioro causado por una conservación en condiciones deplorables, al estar almacenadas en un local en el que se guardaba un grupo indeterminado de perros. Las obras, actualmente propiedad del Museo de l'Hospitalet (Barcelona), han permanecido fuera del circuito artístico hasta la actualidad. Se exponen los primeros resultados de la fase de estudio del soporte de las nueve obras y las propuestas de intervención en los soportes dañados

A study of the effects of PVAC on works of art on paper and wood: pH and colour change

This paper presents the preliminary findings of pH and colour measurements carried out on artworks on paperand on wood that had been treated with a poly(vinyl acetate) (PVAC) based adhesive in the 1980s. In both cases, areas treated with PVAC proved to be less acidic than untreated areas. Contrary to expectations, the conservation treatments have not, as yet, increased acidity levels in the objects under study. Colour measurements of the works on paper showed that those that had been backed with a cotton fabric using a mixture of methylcellulose and PVAC were less yellow than those from the same print run that had not been backed. This finding suggests that the backing somehow prevented the natural degradation of the support. In view of these preliminary results, further research is clearly needed. This study forms part of a broader ongoing project to assess the role of PVAC in the conservation of a range of cultural assets.
