[Possible pleurogenic route in the development of bronchiectasis in children]
Insights
Chronic pneumonia with bronchiectasis involves impaired bronchial motor function, leading to reduced lung evacuation and disease progression. This impacts pleuropulmonary circulation and exacerbates chronic lung conditions.
Area of Science:
- Pulmonology
- Pathophysiology
- Respiratory Medicine
Context:
- Chronic pneumonia with bronchiectasis often follows acute destructive pneumonia with pleurogenous complications.
- Pathogenesis involves pleural adhesions, disrupted pleuropulmonary circulation, and altered bronchial rhythmic activity.
Purpose:
- To investigate the motor activity of bronchial smooth-muscle structures in chronic pneumonia.
- To understand the neuromuscular and sclerotic changes affecting bronchial function.
Summary:
- Reduced tonus and biopotential activity were observed in bronchial smooth muscles.
- Neuromuscular apparatus and muscle fibers undergo sclerotic changes, impairing bronchial evacuation.
- This diminished motor function creates a cycle worsening pleuropulmonary circulation and accelerating disease progression.
Impact:
- Highlights the role of impaired bronchial motor function in chronic pneumonia progression.
- Provides insights into the pathophysiology of chronic unspecific pulmonary diseases.
- Suggests potential targets for therapeutic interventions aimed at improving bronchial function and pleuropulmonary circulation.
Abstract:
Chronic pneumonia with bronchiectases develops often after acute destructive pneumonia with pleurogenous complications. This process is attributed to infection of the pleural adhesions, disorders of pleuropulmonary circulation of blood and lymph, and changes of the rhythmic activity of the bronchi. Study of the motor activity of the smooth-muscle structures of the wall of bronchi involved in a chronic process disclosed sharply diminished tonus and activity of biopotentials. In the initial forms of chronic unspecific pulmonary diseases affection of the neuromuscular apparatus responsible for conduction of the nerve impulse occurred, then the muscle fibres became involved in a sclerotic process, which was attended by reduced evacuation function of the bronchi. The reduction of the bronchial motor function closes the vicious circle of disorders of the pleuropulmonary connections of blood and lymph circulation and is conducive to rapid progress of the chronic process in the lungs.
