Insights

Pediatric unilateral vocal cord paralysis (UVCP) lacks consistent diagnostic and treatment guidelines. More research is essential to understand its prevalence, natural history, and optimal surgical interventions for children.

Area of Science:

  • Pediatric Otolaryngology
  • Pediatric Pulmonology
  • Pediatric Speech-Language Pathology

Background:

  • Unilateral vocal cord paralysis (UVCP) affects multiple pediatric specialties.
  • Iatrogenic injury is a common cause, but data on prevalence and symptom burden vary.
  • Existing literature often conflates UVCP with bilateral vocal cord paralysis (BVCP).

Purpose of the Study:

  • To review the current literature on pediatric UVCP.
  • To identify inconsistencies in diagnosis, treatment, and outcomes.
  • To highlight the need for further research.

Main Methods:

  • Systematic reviews and meta-analyses were included.
  • Retrospective and limited prospective studies were analyzed.
  • Literature was assessed for data on prevalence, symptom burden, and treatment.

Main Results:

  • Significant inconsistencies exist in the diagnosis and treatment of pediatric UVCP.
  • Limited data available on the natural history and long-term outcomes.
  • Lack of consensus on objective/subjective measurements and surgical intervention indications.

Conclusions:

  • The current literature on pediatric UVCP is inconsistent and lacks comprehensive data.
  • Further research is crucial to establish prevalence, natural history, and evidence-based treatment guidelines.
  • Improved understanding is needed for surgical interventions like thyroplasty, injection medialization, and nerve reinnervation.

Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

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.

Esophageal Perforation-I: Introduction01:22

Esophageal Perforation-I: Introduction

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Esophageal Strictures-II: Clinical Features and Management

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...

Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Tracheostomy Decannulation01:21

Tracheostomy Decannulation

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
