ENT manifestations of Wegeners granulomatosis.
Wegeners granulomatosis is a necrotizing granulomatous vasculitis with multisystemic involvement. We present two cases of Wegener's presenting with otological manifestations as the first symptom. These symptoms are subtle and diagnosis may be easily overlooked. Hence a high index of suspicion is required. Early diagnosis and treatment goes a long way in improving the outcomes and in preventing ...
متن کاملNeutrophil chemotaxis in Wegeners granulomatosis and idiopathic pulmonary fibrosis
Background: The presence of anti-neutrophil cytoplasmic antibodies (ANCA) in Wegeners granulomatosis (WG), implicate the neutrophil as a key effector cell. Previous studies have reported elevated neutrophil counts in the lung although the determinants of neutrophil chemotaxis in the WG lung are unknown. Methods: BALF cell counts, myeloperoxidase (MPO) and chemokines were measured in 27 patient...
متن کاملModeling of Fault Co-seismic Displacement Fields in Elastic Environments Based on Spherical Dislocation Theory
This research is based on the modeling of co-seismic deformations due to the fault movement in the elastic environments, and we can obtain the deformations generated in the faults. Here, modeling of the co-seismic displacement field is based on the analytical method with two spherical dislocation model and half-space dislocation model. The difference in displacement field from two spherical and...
متن کاملUnified Theory of Displacement - Covariant Time - Frequency Analysis
We present a theor of linear and quadratic time-frequency representations (&FRs) that are covariant to time-frequency displacement operators. The theory unifies important T F R classes (short-time Fourier transform, wavelet transform; Cohen’s, affine, hyperbolic, and power classes), and it allows the systematic construction of new TFRs that are covariant to a given operator.
متن کاملTheory and Observation of Displacement Phenomena in Coadsorbed Films
Displacement refers to a surprising phenomenon observed in a number of adsorption systems. At low temperatures, some relatively inert gases, such as krypton (Kr) or methane (CH4), are found to displace molecules from preadsorbed monolayer films of a more condensable species, such as carbon tetrachloride (CCl4), from a graphite substrate. We present a simple thermodynamic model to explain displa...
