Sleep Apnea01:21

Sleep Apnea

765
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Asthma-I: Introduction

3.7K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma-II: Pathophysiology and Classification

4.9K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma: Pathogenesis and Management

1.7K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Area of Science:

  • Pulmonology
  • Sleep Medicine
  • Internal Medicine

Background:

  • Obstructive sleep apnea (OSA) and asthma are prevalent respiratory conditions.
  • Both conditions exhibit rising incidence rates in recent years.
  • Asthma and OSA often present concurrently, sharing common predisposing and aggravating factors.

Purpose of the Study:

  • To comprehensively review the relationship between OSA and asthma.
  • To explore their shared epidemiology, pathophysiology, and clinical manifestations.
  • To summarize current diagnostic and treatment advancements.

Main Methods:

  • Literature review of PubMed articles (1990-2015) and key older publications.
  • Keywords used: "OSA" and "asthma".
  • Information synthesized on common features, pathophysiological associations, and treatments.

Main Results:

  • OSA and asthma share numerous commonalities in risk factors and pathophysiology.
  • Potential shared mechanisms include mechanical effects, intermittent hypoxia, inflammation, and hormonal factors.
  • Continuous positive airway pressure (CPAP) treatment for OSA demonstrated improvement in asthma symptoms, leading to the concept of "alternative overlap syndrome".

Conclusions:

  • OSA and asthma are intricately linked in pathogenesis, symptoms, and therapeutic approaches.
  • Increased vigilance for OSA is crucial in patients with difficult-to-control asthma.
  • Further research is necessary to refine clinical management strategies.
