Manejo a largo plazo del paciente atópico

Se describen varios aspectos del manejo de la dermatitis atópica canina: tratamiento de las dermatosis relacionadas o secundarias, tratamiento específico y tratamiento sintomático. Así se describe la terapia frente a las infecciones, el tratamiento de las DAPP, reacción alimentaria, queratoseborrea, otitis externa y dermatitis piotraumática. El tratamiento específico incluye la eliminación de alergenos y la inmunoterapia. En el tratamiento sintomático se pueden usar glucocorticoides, sustancias no esteroides de uso tópico, antihistamínicos, ácidos grasos esenciales y varios antiinflamatorios no esteroideos sistémicos, uno de los cuales es la ciclosporina. La clave del éxito en cada caso es una terapia combinada.

Dermatitis atópica canina : nuevos conceptos

La dermatitis atópica canina es una enfermedad inflamatoria y pruginosa de la piel con predisposición genéica y características clínicas determinadas. La mayoría de las veces está asociada a la producción de IgE frente a alérgenos mediambientales. Se describen los factores intrínsecos y extrínsecos que contribuyen a su desarrollo, así como los fenómenos de umbra y de suma de efectos. Se presenta el cuadro clínico y diagnóstico de la enfermedad.

El empleo de la rifampicina en el tratamiento de las piodermas profundas crónicas del perro : revisión bibliográfica y presentación de trece casos clínicos

Las piodermas profundas crónicas son entidades clínicas difíciles de curar debido a la escasa capacidad de los antibióticos para llegar con suficiente concentración a esas lesiones. La rifampicina es un antibacteriana sistémico de excelente penetración en los tejidos, especialmente en aquéllos que están fibrosados. Después de una revisión bibliográfica de las piodermas y de este antibiótico, los autores realizan dos estudios: uno retrospectivo (ocho casos) y otro prospectivo (cinco casos) que demuestran el interés del empleo de la rifampicina en el tratamiento de este tipo de infecciones cutáneas.Chronic deep pyoderma is difficult to treat owing to the limited capacity of antibiotics to adequately penetrate the lesions. Rifampicin is a systemic antibacterial agent with excellent penetra tian capability, especially in fibrous issues. A review of the literature on pyoderma and rifampicin is presented. Two studies of the efficacy of rifampicin are described, a retrospective study (eight cases) and a prospective study (five cases), which demonstrate the value of rifampicín in the treatment of chronic deep skin infections

Las dermatosis anales y perianales del perro

Después de un recuerdo de la anatomía del ano y de la zona perianal, los autores describen sus principales afecciones dermatológicas, ya sean exclusivas como en el cuadro de dermatosis más generalizadas. Igualmente proponen para cada caso una aproximación diagnóstica y las posibilidades terapéuticas.After a reminder of the anatomy of the anus and the perianal region, the authors describe the principle dermatological diseases of the anus, be the restricted to the anus or symptoms of more wide-spread dermatoses. They outline the diagnostic procedure to be followed and the therapeutical possibilities in each case

Formation, Simulation and Restoration of Hypertelescopes Images

This book is a collection of 19 articles which reflect the courses given at the Collège de France/Summer school “Reconstruction d'images − Applications astrophysiques“ held in Nice and Fréjus, France, from June 18 to 22, 2012. The articles presented in this volume address emerging concepts and methods that are useful in the complex process of improving our knowledge of the celestial objects, including Earth

Apodized pupil Lyot coronagraphs for arbitrary apertures. V. Hybrid Shaped Pupil designs for imaging Earth-like planets with future space observatories

We introduce a new class of solutions for Apodized Pupil Lyot Coronagraphs (APLC) with segmented aperture telescopes to remove broadband diffracted light from a star with a contrast level of $10^{10}$. These new coronagraphs provide a key advance to enabling direct imaging and spectroscopy of Earth twins with future large space missions. Building on shaped pupil (SP) apodization optimizations, our approach enables two-dimensional optimizations of the system to address any aperture features such as central obstruction, support structures or segment gaps. We illustrate the technique with a design that could reach $10^{10}$ contrast level at 34\,mas for a 12\,m segmented telescope over a 10\% bandpass centered at a wavelength $\lambda_0=$500\,nm. These designs can be optimized specifically for the presence of a resolved star, and in our example, for stellar angular size up to 1.1\,mas. This would allow probing the vicinity of Sun-like stars located beyond 4.4\,pc, therefore fully retiring this concern. If the fraction of stars with Earth-like planets is \eta_{\Earth}=0.1, with 18\% throughput, assuming a perfect, stable wavefront and considering photon noise only, 12.5 exo-Earth candidates could be detected around nearby stars with this design and a 12\,m space telescope during a five-year mission with two years dedicated to exo-Earth detection (one total year of exposure time and another year of overheads). Our new hybrid APLC/SP solutions represent the first numerical solution of a coronagraph based on existing mask technologies and compatible with segmented apertures, and that can provide contrast compatible with detecting and studying Earth-like planets around nearby stars. They represent an important step forward towards enabling these science goals with future large space missions.Comment: 9 pages, 6 figures, ApJ accepted on 01/04/201

Particle exchange and residence times in the North Western Mediterranean

The effects of the hydrodynamic processes on the distribution of passive drifters in the Gulf of Lions (GoL) have been investigated using a Lagrangian approach coupled with a 3D circulation model (Symphonie). We consider passive drifters, for which transport processes are determined solely by the 3D flow fields, which are in turn primarily forced by the North Mediterranean Current (NMC) and by the Rhˆone fresh-water inputs. The model reproduces 600 3D Lagrangian trajectories of particles released along the coastal area of the GoL during the winter period (January-February). The GoL has been divided into four sectors, each corresponding to a zone playing a strategic role in the hydrodynamics of the study area. The macroscopic characteristics of the transport on the shelf zone are analyzed in terms of total concentration and residence times of the cluster released in the basin. Particle distributions are strongly related to the mesoscale and sub-mesoscale hydrodynamic structures on the shelf and to the offshore circulation associated with the NMC. Two crucial areas are identified: a dispersive zone, corresponding to the central part of the continental shelf, and a wide offshore zone, representing an area of both aggregation and transition
