1Hospital Universitario La Paz, Madrid, Spain.
Summary
Bronchiectasis is common in severe asthma, linked to more hospitalizations and specific comorbidities like GERD and NSAID sensitivity. This suggests it
Area of Science:
- Pulmonology
- Medical Imaging
Background:
- Bronchiectasis is increasingly recognized in severe asthma patients.
- It may significantly contribute to overall disease severity and complexity.
Purpose of the Study:
- To determine the prevalence of bronchiectasis in severe asthma.
- To characterize clinical features and outcomes of severe asthma patients with bronchiectasis.
Main Methods:
- Retrospective review of 184 severe asthma patients.
- High-resolution thoracic computed tomography (CT) used for diagnosis.
- Comparison of characteristics and outcomes between patients with and without bronchiectasis.
Main Results:
- Bronchiectasis identified in 47% of severe asthma patients.
- Associated with hypersensitivity to NSAIDs, GERD, and higher blood eosinophils.
- Increased asthma exacerbation hospitalizations observed in patients with bronchiectasis.
Conclusions:
- Bronchiectasis in severe asthma is linked to increased hospitalizations and specific comorbidities.
- It may represent a distinct phenotypic feature of severe eosinophilic asthma.
- Highlights the importance of identifying bronchiectasis in severe asthma management.

01:30Toxidromes: Clinical Features
1
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

01:20COPD: Pathogenesis and Clinical Features
1.9K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

703
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...

557
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

354
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
