Concentration of Fibroblasts in the Vocal Fold of Elderly.

Objective: To study the concentration of fibroblasts in the vocal folds of elderly people.

Material And Methods: The vocal folds of 13 cadavers were removed and divided into two age groups: Control group: n-5, 18-40 years; Elderly group: n-8, ≥75 years). The vocal folds were dissected and prepared for immunohistochemical analysis using the SA100 antibody to fibroblasts.

Sectorial Analysis of the Fibrous Matrix of Vocal Folds in the Elderly.

Objective: to determine the sectorial concentration of fibrous matrix along the vocal folds of the elderly.

Methods: Thirteen fresh vocal folds were removed from 13 cadavers. The subjects were divided into two groups: control group (CG) - age range 25-40 years (n = 5), and elderly group (EG), aged ≥70 years (n-8).

Vocal Characteristics of Patients With Morbid Obesity.

Introduction: Obesity modifies vocal characteristics, causing abnormal fat deposition in the abdominal region and upper airways. For some authors the voice of the obese is not different from nonobese and the vocal symptoms are scarce; for others dysphonia in obese is reported by 70% of them and the voice becomes hoarse, breathy, and unstable.

Objective: To characterize the voice of patients with morbid obesity.

Are Vocal Alterations Caused by Smoking in Reinke's Edema in Women Entirely Reversible After Microsurgery and Smoking Cessation?

Background: Reinke's edema is a benign lesion of the vocal folds that affects chronic smokers, especially women. The voice becomes hoarse and virilized, and the treatment is microsurgery. However, even after surgery and smoking cessation, many patients remain with a deep and hoarse voice.

Scanning Electron Microscopy of the Presbylarynx.

Objective: To describe the findings on the presbylarynx under scanning electron microscopy.

Study Design: Cadaver study.

Setting: Universidade Estadual Paulista (Botucatu, São Paulo, Brazil).

Psychogenic dysphonia: diversity of clinical and vocal manifestations in a case series.

Introduction: Psychogenic dysphonia is a functional disorder with variable clinical manifestations.

Objective: To assess the clinical and vocal characteristics of patients with psychogenic dysphonia in a case series.

Methods: The study included 28 adult patients with psychogenic dysphonia, evaluated at a University hospital in the last ten years.

Aging voice: presbyphonia.

Presbyphonia is a physiological process of aging voice that includes morphological changes in the coverage mucosa, muscle, and cartilage. We revised the morphological, endoscopic, and vocal acoustic changes that occur in presbyphonia and discussed some treatments proposed to minimize glottal incompetence and improve vocal performance of the elderly.

Auditory evaluation in patients with type 1 diabetes.

Objectives: We performed a prospective clinical study of the cochleovestibular symptoms and the risk cofactors and characteristics of hearing loss in patients with type 1 diabetes.

Methods: Group 1 consisted of 40 patients with type 1 diabetes, and group 2 consisted of 20 control subjects without diabetes. All participants answered a questionnaire, and their medical records were reviewed.
