Summary
This review found varied outcome measures for inducible laryngeal obstruction (ILO), with few assessing personal and environmental impacts. Standardized measures are needed to capture the full scope of ILO
Area of Science:
- Laryngology and Respiratory Medicine
- Rehabilitation and Allied Health
- Health Services Research
Background:
- Inducible laryngeal obstruction (ILO) is a breathing disorder characterized by inappropriate laryngeal closure.
- Outcome measures are crucial for monitoring health status changes in ILO patients.
- A comprehensive review of existing measures is needed to guide treatment and identify gaps in current tools.
Purpose of the Study:
- To systematically evaluate outcome measures reported in the literature for individuals with ILO.
- To identify consistency in measurement for evidence synthesis in ILO treatment and management.
- To assess if current measures align with the World Health Organization International Classification of Functioning, Disability and Health (WHO-ICF) framework.
Main Methods:
- A systematic literature search was conducted across multiple databases (MEDLINE, EMBASE, CINAHL, Scopus, PsycINFO, Web of Science, Google Scholar) from December 2023 to December 2024.
- Two independent reviewers screened titles, abstracts, and full texts, extracting data using Covidence software.
- Outcomes were categorized by measurement type and alignment with WHO-ICF components.
Main Results:
- A total of 49 full-text articles were included after screening 658 titles and abstracts.
- Patient-reported outcomes were most common (97%), followed by clinician-reported (31%) and performance outcomes (26%).
- While body function, structure, and activity limitations were often considered, personal and environmental factors were rarely addressed within the WHO-ICF framework.
Conclusions:
- Significant variation exists in the outcome measures used in current ILO research.
- Measures assessing personal and environmental impacts of ILO are notably infrequent.
- There is a critical need to establish a consensus core outcome set for ILO research and clinical practice to ensure comprehensive impact assessment and facilitate evidence synthesis.

01:21Larynx
4.0K
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,...

01:26Esophageal Strictures-II: Clinical Features and Management
392
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

01:30Esophageal Strictures-I: Introduction
585
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
436
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

01:25Suctioning the Oropharyngeal Airway
749
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

492
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
