Airway remodelling in cough-variant asthma
Lancet (London, England)
|August 19, 2000
Summary
Subepithelial-layer thickening, a hallmark of airway remodeling, is more pronounced in classic asthma than in cough-variant asthma. Early anti-inflammatory treatment may benefit both asthma types.
Area of Science:
- Pulmonary Medicine
- Pathology
Background:
- Subepithelial-layer thickening is a key feature of airway remodeling in asthma.
- This study quantifies subepithelial-layer thickness in cough-variant asthma, classic asthma with wheezing, and healthy controls.
Discussion:
- Mean subepithelial-layer thickness was 7.1 microm in cough-variant asthma, 8.6 microm in classic asthma, and 5.0 microm in controls.
- Asthma patients exhibited significantly greater thickness compared to healthy individuals.
- Classic asthma showed significantly greater thickness than cough-variant asthma.
Key Insights:
- Airway remodeling, specifically subepithelial-layer thickening, differs in severity between cough-variant and classic asthma.
- Findings suggest a potential for early anti-inflammatory intervention in cough-variant asthma.
Outlook:
- Further research into the specific mechanisms driving differential airway remodeling in asthma subtypes.
- Investigating the long-term efficacy of early anti-inflammatory treatments in cough-variant asthma.

Trachea
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...

Pneumothorax-II
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Oxygen Delivering System III: Tracheostomy and T-piece
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Tracheostomy: Procedure and Tubes
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

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.
