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 […]

Asthma – Symptoms, Treatment and Medications

Definition of Asthma Asthma is a disease of the airways that results in narrowing of the airways (bronchospasm) and INFLAMMATION in response to a wide range of inhaled irritants such as pollen, mold, smoke, chemicals, and the airborne debris of pests ranging from cockroaches to microscopic dust mites. This narrowing, or airflow obstruction, is usually reversible when […]

Living with Chronic Pulmonary Disease

Chronic Pulmonary Disease – Introduction More than 30 million Americans live with chronic pulmonary conditions such as ASTHMA, CYSTIC FIBROSIS, PULMONARY FIBROSIS, and CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD). Though many chronic pulmonary conditions are far more common among people over age 50, chronic pulmonary disease affects young people too. Chronic pulmonary disease requires most people to make accommodations in […]

Atelectasis – Definition, Symptoms and Treatment

Definition of Atelectasis Atelectasis is the collapse of a segment or lobe of the lung, or an entire lung – is fairly common and most often spontaneously corrects itself for full recovery. The collapse may result from obstruction, structural damage to lung tissue, fibrosis that destroys bronchial segments, PNEUMOTHORAX, PLEURAL EFFUSION, and other causes. A form of […]

Lung Abscess – Symptoms, Causes and Treatment

Definition of Lung Abscess Lung abscess is a pocket of INFECTION deep within the lung that isolates itself within a defined area of the lung (having a clear boundary between the infected tissue and the healthy tissue), usually behind a blocked segment of BRONCHUS. Symptoms, Causes and Treatment A lung abscess often follows a known bacterial INFECTION such as PNEUMONIA or BRONCHITIS in which INFLAMMATION or excessive […]

Berylliosis – Definition, Symptoms and Treatment

Definition of Berylliosis Berylliosis is chronic damage to the LUNGS, also called chronic beryllium disease, resulting from industrial exposure to beryllium, a heavy metal that has many commercial uses and applications in contemporary manufacturing processes. Inhaled beryllium fumes and dust cause irritation to the delicate alveoli that activates the body’s IMMUNE RESPONSE. In the United States berylliosis occurs primarily […]

Pleural Effusion – Definition, Causes, Symptoms and Treatment

Definition and Causes of Pleural Effusion An increase in the amount of fluid between the PLEURA. In health there is a very small amount of fluid, only 10 to 20 milliliters, within the pleural cavity. A pleural effusion can contain upward of 2 liters of fluid, though much smaller quantities (less than 400 milliliters) are […]

Bronchiectasis – definition, symptoms and treatment

Definition of Bronchiectasis The dilation of a segment of BRONCHUS. Bronchiectasis may involve several bronchial branches and usually occurs deep within the lung, often in a lower lobe. Though bronchiectasis may be congenital (present at birth) or acquired (develop after birth), congenital bronchiectasis is rare and results when only the core structure of the LUNGS develops and existing […]

Pleurisy – definition, causes, symptoms and treatment

Definition of Pleurisy and Causes Pleurisy is INFLAMMATION of the PLEURA, also called pleuritis – can develop as a consequence of direct irritation or INFECTION in the pleural space, or as a consequence of infection or INFLAMMATION involving the LUNGS such as TUBERCULOSIS or PNEUMONIA. AUTOIMMUNE DISORDERS can cause inflammation, such as SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) and SARCOIDOSIS. Symptoms The characteristic symptom of pleurisy is sudden, sharp, and often severe pain during inhalation and […]

Bronchitis – Acute and Chronic – symptoms and treatment

Definition of Bronchitis INFLAMMATION of the bronchi, the airways that branch from the TRACHEA into the LUNGS. Bronchitis may be viral, bacterial, or the result of irritation such as cigarette smoking or exposure to environmental pollutants. It may also occur as an acute condition that comes on suddenly, runs its course, and heals without lasting […]
