Validation and reliability analysis of the Questionnaire on the Emotional Impact of Vertigo-CIEV version translated to the Brazilian Portuguese language.

Purpose: To determine the internal consistency and reliability of the "Questionário de Impacto Emocional da Vertigem (CIEV)" and to validate the instrument with respect to the Dizziness Handicap Inventory (DHI) in a sample of individuals with balance disorders.

Methods: 38 subjects participated in the study, males and females, aged from 23 to 85 years, who presented dizziness, vertigo, and/or falls complaints and attended to the Vestibular Disorders clinic at the University Hospital.

Proposal of standardization of Horus® computerized posturography in adults.

Purpose: To propose a normalization model of a posturography platform in adults without changes in body balance, through descriptive analysis by age group and sex.

Methods: Cross-sectional observational study. Adults, with no changes in body balance and no vestibular complaints were submitted to 6 sensory conditions on the Horus® posturography platform.

Correlation between vascular endothelial growth factor expression and presence of lymph node metastasis in advanced squamous cell carcinoma of the larynx.

Introduction: Squamous cell carcinoma is the most common neoplasm of the larynx, and its evolution depends on tumor staging. Vascular endothelial growth factor is a marker of angiogenesis, and its expression may be related to increased tumor aggressiveness, as evidenced by the presence of cervical lymphatic metastases.

Objectives: To evaluate the expression of the vascular endothelial growth factor marker in non-glottic advanced squamous cell carcinoma of the larynx (T3/T4) and correlate it with the presence of cervical lymph node metastases.

Complete gonadal dysgenesis in clinical practice: the 46,XY karyotype accounts for more than one third of cases.

Design: Retrospective study based on data from all patients with CGD seen in our service from 1989 to 2010.
