These data show that AR is common in the Middle East region as elsewhere in the world. Many patients with AR in Middle East region suffer from their symptoms (e.g., runny nose, nasal itching, nasal congestion, postnasal drip, and other symptoms) on all or most days during the times of the year that their allergies are worst. These symptoms have been shown to reduce QOL and performance at work/school to a significant degree. Additionally, the survey data underscore a considerable treatment gap with current therapies for AR and that many AR patients still have not found adequate effectiveness with currently available medications. Thus, through identification of disease impact on the Middle East population and highlighting treatment gaps, clinicians in the Middle East may better understand and treat AR, leading to improvements in overall patient satisfaction and QOL.

Profiles of gasdynamic parameters in self-similar blast waves, taking into account the influence of conduction and radiation fluxes due to high temperatures attained at the centre, are determined. In the blast-wave equations these fluxes are expressed in terms of the Fourier law for heat conduction and a differential expression for radiative transport in a semi-grey gas model. Various boundary conditions are considered in order to account for different ways in which blast waves are initiated and driven. Similarity requirements are implemented in the solution by compatible functional forms of gas conductivity and absorptivity, as well as the opacity of the shock front. This formulation yields a two-point boundary-value problem, which is then transformed into an initial-value problem in order to facilitate the integration. As a particular example, a detailed solution for the constant-energy case is obtained, covering the whole range of relative heat-transfer effects expressed in terms of radiative to gasdynamic energy fluxes, from the adiabatic flow field, on one extreme, to the isothermal, on the other.

In properly selected patients with penile cancer organ sparing surgery provides comparable oncologic outcomes to conventional techniques, including total and subtotal amputations. Many patients are able to urinate while standing and a significant number are able to have intercourse.
