EMPHYSEMA Emphysema is defined as abnormal permanent enlargement of air spaces distal to the terminal bronchioles, accompanied by the destruction of the walls and without obvious fibrosis. The 3 described morphological types of emphysema are centriacinar, panacinar, and paraseptal
PNEUMOTHORAX A collapsed lung, or pneumothorax, occurs when all or part of a lung collapses or caves inward. This occurs when air gets in the area between the lung and chest wall. When this happens the lung cannot fill up with air, breathing becomes hard, and the body gets less oxygen. A collapsed lung can occur spontaneously in a healthy person or in someone who has lungs compromised by trauma, asthma, bronchitis, or emphysema. Update Date: 12/3/2004
TUBERCULOSIS Tuberculosis (TB) is a contagious bacterial disease that primarily involves the lungs. Like the common cold, it spreads through the air. Only people who are sick with TB in their lungs are infectious. When infectious people cough, sneeze, talk or spit, they propel TB germs, known as bacilli, into the air. A person needs only to inhale a small number of these to be infected. TB can also affect other parts of the body, such as the brain, the kidneys or the spine.
SARCOIDOSIS What is sarcoidosis? Sarcoidosis is an inflammatory disease that affects multiple organs in the body, but mostly the lungs and lymph glands. In patients with sarcoidosis, abnormal masses or nodules (called granulomas) consisting of inflamed tissues form in certain organs of the body. These granulomas may alter the normal structure and possibly the function of the affected organ(s
PULMONARY FIBROSIS Pulmonary fibrosis is a disease where scar tissue develops in the lungs following many infections and swelling. The scar tissue causes the lungs to become more stiff than normal. This means that the lungs cannot expand like normal, and therefore less air can get in and out of the lungs.
GRANULOMA The human immune system, which protects us from disease, is made up of a complex network of highly specialized cells and organs. When any part of this network is faulty, it interrupts the smooth functioning of the immune response and can result in an immulogic disorder. Chronic granulomatous disease (CGD) is actually a group of rare, inherited disorders of the immune system that are caused by defects in the immune system cells called phagocytes. These defects leave patients vulnerable to severe recurrent bacterial and fungal infections and chronic inflammatory conditions such as gingivitis (swollen inflamed gums), enlarged lymph glands, or tumor-like masses called granulomas. While not malignant, granulomas can cause serious problems by obstructing passage of food through the esophagus, stomach, and intestines as well as blocking urine flow from the kidneys and bladder
What is interstitial lung disease (ILD) / pulmonary fibrosis? Interstitial lung disease (ILD) is a broad category of lung diseases that includes more than 130 disorders characterized by scarring (i.e. “fibrosis”) and / or inflammation of the lungs. Some of the disorders included under the heading of ILD are: Idiopathic pulmonary fibrosis Hypersensitivity pneumonitis Sarcoidosis Eosinophilic granuloma Chronic eosinophilic pneumonia Bronchiolitis obliterans Lymphangioleiomyomatosis
A chronic, progressive condition of scar tissue build-up in the lungs resulting from the inhalation of asbestos fibers. Shortness of breath, increased risk of lung infection and permanent lung damage are common symptoms of asbestosis. ASBESTOSIS
