The Expression of Hypoxia-Related Biomarkers: A Significance of HIF-1α C1772T Polymorphism as Predictor of Laryngeal Carcinoma Relapse.

Introduction: The association between the expression of HIF-1α in the laryngeal carcinoma and the prognosis of disease is quite well documented, but the significance of HIF-1α C1772T polymorphism and its relation to disease phenotype have to be clarified. The aim of this study was to investigate the influence of C1772T polymorphism on the clinical-pathological characteristics and disease-free survival after initial surgical treatment of patients with laryngeal carcinoma.

Materials And Methods: The prospective cohort study included 65 patients with laryngeal carcinoma.

Is Computed Tomography Imaging of Deviated Nasal Septum Justified for Obstruction Confirmation?

Third-party payers request objective confirmation of the nasal septum deviation (NSD) severity by computed tomography (CT) before authorizing financial support for septoplasty. Previous studies have provided contradictory results related to the link between obstruction severity and CT-measured angle of the NSD. The aim of this study was to investigate whether the diverse CT morphology of NSDs (including previously neglected types and shapes) could predict obstruction severity.
