BACKGROUND In recent decades several groups of researchers have been interested in describing and understanding vocal morbidity in teachers in order to explain the large number of teachers diagnosed with dysphonia and account for the absenteeism attributed to vocal disability. AIMS To determine the proportion of teachers who reported a diagnosis of dysphonia and measure associations between i...

OBJECTIVE The aim of this study was to investigate the relationship between acoustic analysis and biopsychosocial implications of voice problems, evaluated by the Voice Handicap Index (VHI). MATERIALS AND METHODS The study comprised 120 female teachers with voice disorders, evaluated by videolaryngostroboscopy. 60.8% of this group were diagnosed as having functional dysphonia and 39.2% had dy...

This case-control study aimed to test the association between voice disorders and job stress among public schoolteachers in São Paulo, Brazil. The groups consisted of teachers with (n = 165) and without (n = 105) voice-related complaints. Both groups answered the questionnaires Conditions of Vocal Production and Job Stress Scale. Analysis of cases and controls showed comparable samples, differi...

Responding to others' emotional expressions is an essential and early developing social skill among humans. Much research has focused on how infants process facial expressions, while much less is known about infants' processing of vocal expressions. We examined 8-month-old infants' processing of other infants' vocalizations by measuring event-related brain potentials (ERPs) to positive (infant ...

OBJECTIVE High voice users (individuals who demonstrate excessive or loud vocal use) are at risk for developing voice disorders. The objective of this study was to examine, both acoustically and perceptually, vocal changes in healthy speakers after an acute period of high voice use. METHODS Members of a university women's volleyball team (n = 12) were recorded a week before (pre) and week aft...

To examine the influences of facial versus vocal cues on infants' behavior in a potentially threatening situation, 12-month-olds on a visual cliff received positive facial-only, vocal-only, or both facial and vocal cues from mothers. Infants' crossing times and looks to mother were assessed. Infants crossed the cliff faster with multimodal and vocal than with facial cues, and looked more to mot...

The effects of preferred stimulation on the vocal stereotypy of 2 individuals were evaluated in two experiments. The results of Experiment 1 showed that (a) the vocal stereotypy of both participants persisted in the absence of social consequences, (b) 1 participant manipulated toys that did and did not produce auditory stimulation, but only sound-producing toys decreased his vocal stereotypy, a...

Jet ventilation (JV) involves high-pressure ventilation for upper laryngeal laser procedures. Anesthetic management for the patient undergoing JV can be challenging, as complications of JV can include subcutaneous emphysema and tension pneumothorax. A 52-year-old woman with a diagnosis of vocal cord polyps presented for direct microlaryngoscopy and laser laryngoplasty with JV. Intraoperatively,...
