Summary
Thyroid disorders like hypothyroidism and hyperthyroidism impact voice quality. Drug therapy improved acoustic measures for hypothyroidism, while both groups showed noticeable perceptual voice changes.
Area of Science:
- Endocrinology
- Speech and Language Pathology
Background:
- Thyroid gland disorders, including hypothyroidism and hyperthyroidism, can affect vocal function.
- Assessing voice changes is crucial for understanding the impact of these endocrine conditions.
Purpose of the Study:
- To investigate the acoustic and perceptual voice characteristics in patients with hypothyroidism and hyperthyroidism.
- To evaluate the effects of drug therapy on voice parameters six months after diagnosis.
Main Methods:
- Included 47 female outpatients diagnosed with hypothyroidism or hyperthyroidism.
- Assessed acoustic, perceptual (using the GRBAS scale), and aerodynamic voice parameters before and after drug therapy.
Main Results:
- Hypothyroidism patients showed significant changes in amplitude perturbation, jitter, and noise-to-harmonics ratio post-treatment.
- Hyperthyroidism patients had significant changes in maximum phonation time; both groups exhibited notable perceptual voice deviations.
Conclusions:
- Thyroid disease significantly affects voice quality.
- While acoustic changes may be minor, perceptual voice deviations are prominent in patients with hypothyroidism and hyperthyroidism, even after treatment.

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

01:23The Thyroid Gland
6.8K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

19.2K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

7.9K
When a force is applied parallel to the top surface of a solid, it resists the applied force due to the internal frictional forces between the layers of the solid known as shearing resistance. However, when the force is removed, the shearing forces restore the original shape of the solid. Other deformation forces also cause temporary changes in shape if the forces are not beyond a threshold magnitude. Solids tend to retain their shape, making the study of their rest and motion easier. Beyond...

Fluids differ from solids primarily in their molecular structure and stress response. Solids have tightly packed molecules with strong intermolecular forces, maintaining their shape and resisting deformation. In contrast, fluids have molecules spaced farther apart with weaker forces, allowing them to flow and deform easily.
Fluids, which include both liquids and gases, are substances that deform continuously under shearing stress. For example, water and oil are liquids with molecules that can...

The Bipolar Junction Transistor (BJT), specifically in a common-emitter configuration, exhibits distinct current-voltage characteristics crucial for understanding its behavior in electronic circuits. These characteristics are established through experimental measurements of voltage and current relationships.
For input characteristics, the base-emitter voltage is varied, maintaining a constant collector-emitter voltage. This setup reveals a Shockley-type dependence of the collector current on...
