Summary
Neoplasm is a common cause of vocal cord paralysis (VCP). A thorough evaluation, including CT-scanning, is recommended for diagnosing VCP and determining its etiology.
Area of Science:
- Otolaryngology
- Diagnostic Imaging
- Neoplastic Diseases
Context:
- Vocal cord paralysis (VCP) has diverse etiologies.
- Current diagnostic approaches for VCP lack standardized consensus.
- Evaluating unilateral vocal cord paralysis (UVCP) requires a systematic approach.
Purpose:
- To establish the common etiologies of VCP.
- To assess the efficacy of various diagnostic methods for VCP.
- To propose an algorithm for the evaluation of UVCP.
Summary:
- Neoplasm accounts for 34% of UVCP and 24% of bilateral VCP (BVCP) cases.
- Surgical trauma is implicated in 12% of UVCP and 24% of BVCP.
- CT-scanning emerged as the most effective diagnostic tool, while thyroid scanning was least effective.
Impact:
- Highlights the significant role of neoplasms in VCP etiology.
- Recommends a diagnostic algorithm for UVCP, including imaging and endoscopy.
- Suggests a follow-up protocol for idiopathic VCP, emphasizing serial imaging.

Myasthenia Gravis: Diagnostic Tests
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

Larynx
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...

Respiratory 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:

Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Pneumothorax II: Pathophysiology
Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...
