Larynx01:21

Larynx

1.1K
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,...

Esophageal Strictures-II: Clinical Features and Management

27
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...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

1.3K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Esophageal Strictures-I: Introduction

44
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...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

945
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...

Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

29
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
Clinical Manifestations:

Summary

Exercise-induced laryngeal obstruction (EILO) in adolescents can be effectively treated with respiratory retraining. This case study shows significant symptom improvement and enhanced breathing techniques after speech-language pathologist intervention.

Area of Science:

  • Laryngology and Respiratory Medicine
  • Pediatric Pulmonology
  • Speech-Language Pathology

Background:

  • Exercise-induced laryngeal obstruction (EILO) is characterized by exertional laryngeal adduction, leading to airway constriction and dyspnea.
  • Respiratory retraining with a speech-language pathologist (SLP) is the standard treatment for EILO.
  • Limited research exists on the typical treatment trajectory of EILO in adolescent populations.

Purpose of the Study:

  • To describe the clinical procedures and considerations for managing EILO in an adolescent patient.
  • To present a case study detailing the diagnosis, treatment, and outcomes of EILO in a 13-year-old female.

Main Methods:

  • Detailed case history including a 2-year history of episodic dyspnea triggered by exertion, scents, and humidity.
  • Laryngeal imaging to identify arytenoid twitching and paradoxical vocal fold motion during inhalation.
  • Speech-language pathology intervention focusing on respiratory retraining and rescue breathing techniques.

Main Results:

  • The adolescent patient experienced symptoms including inhalation difficulty, throat tightness, and biphasic stridor, impacting athletic participation and causing distress.
  • Laryngeal imaging confirmed partial to complete laryngeal adduction upon inhalation.
  • Following three SLP treatment sessions, the patient demonstrated proficiency in rescue breathing, reported improved EILO symptoms, and showed a 14-point improvement in the Post-therapy Dyspnea Index.

Conclusions:

  • This case report supports existing literature on EILO, highlighting its nature and clinical implications.
  • Respiratory retraining delivered by an SLP is an effective treatment for EILO in adolescents, leading to significant symptom relief and functional improvement.
  • The findings underscore the importance of tailored SLP interventions for managing EILO and improving quality of life in young patients.
