Summary
Rheumatoid Arthritis (RA) frequently causes laryngeal issues, with 72.4% of patients showing changes. However, voice disorders (dysphonia) were less common at 12.8% and not linked to disease activity.
Area of Science:
- Otolaryngology
- Rheumatology
- Clinical Medicine
Background:
- Laryngeal involvement in Rheumatoid Arthritis (RA) is common, ranging from 13-75%.
- Manifestations include cricoarytenoid arthritis and vocal fold rheumatoid nodules.
- Understanding these laryngeal effects is crucial for RA patient care.
Purpose of the Study:
- To determine the prevalence of dysphonia and videolaryngoscopy findings in RA patients.
- To investigate the association between laryngeal alterations and RA disease activity.
Main Methods:
- A cross-sectional study compared RA patients with a control group.
- Evaluated disease activity using DAS-28, laryngeal symptoms, Voice Handicap Index, and videolaryngoscopy.
- Assessed 47 RA patients and 40 controls.
Main Results:
- Prevalence of dysphonia was 12.8% and videolaryngoscopy changes was 72.4% in RA patients.
- Posterior laryngitis was the most frequent diagnosis (44.7%).
- No significant association was found between laryngeal disorders and disease activity (p = 0.713).
Conclusions:
- A high prevalence of laryngeal disorders (72.4%) exists in RA patients.
- Dysphonia affects 12.8% of RA patients.
- Laryngeal disorders in RA are not significantly related to disease activity.

01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:24T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:31Respiratory System Abnormal Finding II: Palpation and Auscultation
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

01:13Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
