Demography, Spectrum, and Characteristics of Symptoms Associated With Post-operative Relief After Cholecystectomy.

Background Cholecystectomy is one of the most commonly performed surgical procedures, and it is indicated for symptomatic gallstone disease. Symptoms of gallstone disease vary; many patients complain of the persistence of symptoms post-operatively. Hence, it is imperative to know the characteristics of symptoms that predict post-operative resolution.

Phyllodes tumour is a rare breast tumour with potential of malignancy. Recurrence in phyllodes tumour may also be suggestive of malignant transformation. We report a case of 29-year-old woman with recurrent phyllodes tumour infiltrating the latissimus dorsi reconstruction flap.

The Development of a Model to Examine Source-Receptor Relationships for Visibility on the Colorado Plateau.

This paper describes the development and application of the Visibility and Haze in the Western Atmosphere (VISHWA) model to understand the source-receptor relationships that govern chemical species relevant to visibility degradation in the western United States. The model was developed as part of a project referred to as Visibility Assessment for Regional Emission Distributions (VARED), the objective of which is to estimate the contributions of various geographical regions, compounds, and emission sources to light scattering and absorption by particles on the Colorado Plateau. The VISHWA model is a modified version of a comprehensive Eulerian model, known as the Acid Deposition and Oxidant Model.
