Evaluation of Soluble HLA-G Serum Level as Diagnostic Biomarker in Allergic Rhinitis Patients and its Association with Specific IgE Levels.

About 30 % of people are affected by allergic rhinitis (AR). Allergic rhinitis is an inflammatory condition defined by a disturbance of immunoregulation generating an amplified T helper "Th-2" response. An inflammatory mechanism mediated by HLA-G is thought to be involved through initiation of Th2 cytokine profile releasing "interleukin IL-3, IL-4, and IL-10".

MRI as an Alternative to Second Look Mastoid Surgery.

The main goal of surgery of cholesteatoma is eradication of the disease and revision surgery is indicated when a dry and safe ear has not been achieved. Residual cholesteatoma usually occurs at the sites that are difficult to reach with an operating microscope, such as posterior tympanum and anterior epitympanic recess. Computed tomography can be performed to delineate the extent of disease.
