Cystic Fibrosis and the Lungs – Symptoms and Treatment

Definition of Cystic Fibrosis Cystic fibrosis is an inherited genetic disorder affecting mucus production and clearance, cystic fibrosis alters the functioning of exocrine glands throughout the body and affects nearly all of the body’s systems. In the lungs, cystic fibrosis causes changes in the consistency and composition of the mucus the lungs secrete. The mucus accumulates along the inner […]

Hemoptysis – Definition and Causes

Definition of Hemoptysis Hemoptysis is bleeding from the lungs, which typically manifests through blood in the sputum. It is typically frothy and bright red, though can sometimes be difficult to distinguish from blood that might originate in the esophagus or stomach. Hemoptysis that produces a volume of blood greater than the equivalent of two or three teaspoonfuls is a medical emergency that may represent […]

Legionnaires’ Disease – Symptoms and Treatment

Definition of Legionnaires Disease Legionnaires’ disease is a serious and potentially fatal form of pneumonia first identified in 1976 when several hundred people attending a Legionnaires’ convention became ill, a number of whom died as a result of the infection. Scientists subsequently isolated the causative bacterium Legionella pneumophila. The bacteria infect about 18,000 people in the United […]

Pulmonary Hypertension – Symptoms and Treatment

Definition of Pulmonary Hypertension Elevated blood pressure in the pulmonary arteries and the arteries within the lungs. Pulmonary hypertension develops when the arteries in the lungs become stiff and narrowed, increasing the resistance blood encounters in trying to flow through them. The condition typically starts in the smallest of arteries, the arterioles, and progressively involves larger arteries until pressure within the […]

Pneumoconiosis – Definition, Symptoms and Treatment

Definition of Pneumoconiosis Pneumoconiosis is the collective term for pulmonary conditions that result from occupational exposure to dust and fiber irritants. The conditions result in the same end-stage disease, pulmonary fibrosis, though follow different patterns of progression, depending on the substance and exposure patterns. The primary forms of pneumoconiosis that occur in the United States are Anthracosis, […]

Acute Respiratory Distress Syndrome (ARDS) – Symptoms and Treatment

Acute Respiratory Distress Syndrome (ARDS) Definition Acute Respiratory Distress Syndrome (ARDS) is a complex of symptoms, formerly called adult respiratory distress syndrome, in which respiratory distress and respiratory failure develop accompanying severe illness or trauma. ARDS involves the whole of both lungs, as the lungs become inflamed and fill with fluid. ARDS may develop as a consequence […]

Pneumonia – Symptoms, Treatment and Causes

Definition of Pneumonia Pneumonia is inflammation of the lungs, usually the result of an infection, that causes the alveolar sacs to fill with fluid or pus. It is the most serious consequence of influenza, and in combination with influenza is the seventh leading cause of death in the United States. Pneumonia may be lobar, affecting the entire lobe of the […]

Asbestosis – Definition, Symptoms and Treatment

Definition of Asbestosis Asbestosis is damage to the lungs resulting from inhalation of asbestos fibers. During the first half of the 20th century asbestos, a natural substance mined from underground, became common in insulating materials because of its natural heat resistance. In the 1950s researchers linked chronic asbestos inhalation with pulmonary fibrosis and a rare form of lung cancer, mesothelioma, found […]

Pulmonary edema – symptoms, causes and treatment

Definition of Pulmonary Edema Pulmonary Edema is Abnormal fluid accumulation within the alveoli and the interstitial tissues of the lungs, typically resulting from cardiovascular disease (cvd)such as heart failure or cardiomyopathy. Pneumonia, acute respiratory distress syndrome (ards), smoke inhalation, near drowning, and high altitude can also cause pulmonary edema. Pulmonary edema can be a life-threatening condition and requires immediate medical evaluation […]

Aspergillosis – Definition, Symptoms and Treatment

Definition of Aspergillosis Aspergillosis is an opportunistic fungal (yeast) infection that can manifest as pneumonia in people who have hiv/aids, are undergoing chemotherapy to treat cancer, receive immunosuppressive therapy after organ transplantation, or are otherwise immunocompromised. Aspergillosis may also occur as an allergic reaction (called allergic bronchopulmonary aspergillosis or ABPA) in people who have asthma or cystic fibrosis, causing airway inflammation and fluid accumulation in the lungs. Aspergillus, the infective fungus, is common in […]
