Lung diseases

Alpha-1 antitrypsin deficiency
Alpha-1-antitrypsin deficiency (A1AD) is a hereditary disorder characterized by low levels of a protein called alpha-1-antitrypsin (A1AT) which is found in the blood. Alpha 1-antitrypsin is a blood protein that diffuses into tissue spaces to protect tissues from being harmed by enzymes released from cells when they are injured and inflamed.
Bronchopulmonary dysplasia
Bronchopulmonary dysplasia is a condition that may develop in some preterm infants, in which the infant remains dependent on artificial ventilation and then oxygen for several months. Bronchopulmonary dysplasia occurs most often in premature newborns that had severe lung disease at birth, particularly in those who needed treatment with a ventilator for more than a few weeks after birth.
COPD (chronic Obstructive pulmonary disease)
Chronic obstructive pulmonary disease (COPD) is persistent obstruction of the airways occurring with emphysema, chronic bronchitis, or both disorders. Chronic obstructive pulmonary disease (COPD) encompasses two groups of lung disease, chronic bronchitis and emphysema. Chronic obstructive pulmonary disease is caused by exposure to noxious gases or particles, especially cigarette smoke.
Emphysema is a lung disease that reduces the ability of the lungs to expel air, a process which depends upon the natural rubber-band-like quality or elastic properties of the lungs. Emphysema is a type of chronic obstructive airway disease, or COPD. People with COPD have limitations in the flow of air through their airways. Emphysema involves the gradual destruction of alveoli in the lungs.
Lymphangioleiomyomatosis (LAM)
Lymphangioleiomyomatosis, commonly known as LAM, is a rare disorder of unknown etiology characterized by an unusual type of muscle cell that invades the tissues of the lungs, including the airways, and blood and lymph vessels. The symptoms of Lymphangioleiomyomatosis may include shortness of breath, coughing, and/or difficulty breathing (dyspnea), especially following periods of exercise or exertion.
Pulmonary embolism
Pulmonary embolism is an obstruction of a blood vessel in the lungs, usually due to a blood clot, which blocks a coronary artery. Pulmonary embolism is the sudden blockage of an artery in the lung. The most common cause of pulmonary embolism is a blood clot that forms in a deep vein in your leg, breaks loose, travels to the lungs, and becomes trapped in one of the smaller lung arteries.
Pulmonary hypertension
Pulmonary hypertension (PH) is a rare lung disorder in which the blood pressure in the pulmonary artery (the artery leaving the right side of the heart and going to the lungs) rises far above normal levels. Pulmonary hypertension begins when tiny arteries in your lungs become narrow or blocked. This causes increased resistance to blood flow in your lungs, which in turn raises pressure within the pulmonary arteries.
Infant respiratory distress syndrome
Infant respiratory distress syndrome is a breathing disorder that is present at birth. Infant respiratory distress syndrome was previously known as hyaline membrane disease. Infant respiratory distress syndrome is caused by lack of surfactant in the lungs of premature infants. This surfactant is chemically di-palmitoul-lecithin. This lack of surfactant leads to the collapse of lung alveoli.
Adult respiratory distress syndrome
Adult respiratory distress syndrome (ARDS), also called acute respiratory distress syndrome, is a type of lung (pulmonary) failure that may result from any disease that causes large amounts of fluid to collect in the lungs. Adult respiratory distress syndrome is a breakdown in the function of the lungs that comes on suddenly. Acute respiratory distress syndrome (ARDS) is a type of severe, acute lung dysfunction affecting all or most of both lungs.
Sarcoidosis is a multisystem granulomatous disorder of unknown etiology, characterized histologically by noncaseating epithelioid granulomas involving various organs. The disease is characterised by the presence of non-caseating granulomas which can appear almost anywhere in the body but usually appear in either the lungs or the lymph nodes. Sarcoidosis usually starts in the lungs or lymph nodes in the chest.
Atelectasis is the collapse of part or all of a lung by blockage of the air passages (bronchus or bronchioles), or by very shallow breathing. Atelectasis is a process whereby a segment of lung is not ventilated and becomes "collapsed." Anesthesia, prolonged bed rest with few changes in position and shallow breathing, and underlying lung diseases are risk factors for atelectasis.
Pulmonary alveolar proteinosis
Pulmonary alveolar proteinosis is a rare lung disorder characterized by the filling of the air sacs of the lungs (alveoli) with grainy material consisting mostly of protein and fat. Pulmonary alveolar proteinosis is increasingly being recognized as an important cause of diffuse pulmonary disease. Symptoms of pulmonary alveolar proteinosis include mild shortness of breath associated with a nonproductive or minimally productive cough, weight loss, and fatigue.
Cystic fibrosis
Cystic fibrosis is a hereditary disease of the exocrine glands, usually developing during early childhood and affecting mainly the pancreas, respiratory system, and sweat glands. It is characterized by the production of abnormally viscous mucus by the affected glands, usually resulting in chronic respiratory infections and impaired pancreatic function. Cystic fibrosis is also called mucoviscidosis.
Severe acute respiratory syndrome (SARS)
Severe acute respiratory syndrome (SARS) - a contagious and sometimes fatal respiratory illness - first appeared in China in November 2002. SARS is a severe form of pneumonia, where infected individuals develop a fever, followed by respiratory symptoms such as cough, shortness of breath or difficulty breathing. Scientists have determined that SARS is caused by a new form of the coronavirus never before seen in humans.
