Pulmonary thromboembolism (PTE), commonly referred to as pulmonary embolism, is a potentially life-threatening condition caused by the obstruction of the pulmonary arteries by thrombi, typically originating from deep veins in the lower extremities. It constitutes a major component of venous thromboembolism (VTE), alongside deep vein thrombosis (DVT). The prompt recognition and treatment of PTE are
Pulmonary multi-drug resistant Mycobacterium tuberculosis (MDR-TB) represents a severe and escalating public health crisis, marked by resistance to at least isoniazid and rifampin, the two most potent first-line antitubercular drugs. This resistance complicates treatment, prolongs infectiousness, and elevates mortality rates. The disease primarily affects the lungs, facilitating airborne transmission and making containment efforts challenging in
Pulmonary hypertension associated with interstitial lung disease (PH-ILD) is a complex and progressive cardiopulmonary disorder in which elevated pulmonary arterial pressure occurs secondary to chronic fibrotic lung disease. This combination significantly worsens morbidity and mortality in affected individuals. Understanding the intersection of these two pathologies is critical for early detection, appropriate classification, and individualized treatment
Pulmonary emphysema is a serious and progressive lung condition characterized by the destruction of alveolar walls, leading to reduced oxygen exchange and difficulty breathing. While most cases of emphysema are linked to smoking and environmental factors, a specific genetic condition known as alpha-1-proteinase inhibitor deficiency (alpha-1 antitrypsin deficiency) plays a crucial role in the development
Pulmonary edema is a serious condition characterized by fluid accumulation in the lungs, leading to impaired oxygen exchange and difficulty breathing. When caused by chronic heart failure, pulmonary edema is a complex and progressive issue that significantly impacts the patient’s quality of life. Understanding the relationship between heart failure and pulmonary edema is essential for
Pulmonary cryptococcosis is a life-threatening fungal infection caused by the Cryptococcus species, most commonly Cryptococcus neoformans and Cryptococcus gattii. These fungi primarily affect the lungs, though they can disseminate to other organs such as the brain, particularly in individuals with weakened immune systems. Pulmonary cryptococcosis is a significant health concern due to its potential to
Pulmonary coccidioidomycosis, commonly known as Valley fever, is a fungal infection caused by the Coccidioides species. This disease primarily affects the lungs but can spread to other parts of the body, resulting in a condition known as disseminated coccidioidomycosis. While coccidioidomycosis is generally endemic to arid regions of the southwestern United States, parts of Mexico,
Pulmonary capillary hemangiomatosis (PCH) is an extremely rare lung disorder characterized by the abnormal growth of blood vessels in the pulmonary capillaries. This condition results in the formation of capillary-like blood vessels within the lungs, leading to significant changes in lung structure and function. While the disease is not widely known, its potential for causing
Pulmonary blastomycosis is a serious fungal infection that primarily affects the lungs. Caused by the Blastomyces dermatitidis fungus, this disease is commonly found in certain areas with high humidity, such as the Mississippi and Ohio River valleys, parts of the Great Lakes, and the southeastern United States. The infection can lead to severe respiratory issues
Pulmonary aspergillosis refers to a spectrum of lung infections caused by the fungus Aspergillus. This condition primarily affects individuals with weakened immune systems, chronic lung diseases, or pre-existing respiratory conditions. The infection can range from mild, asymptomatic cases to severe and life-threatening situations, especially in immunocompromised individuals. Early detection, proper diagnosis, and effective treatment are
