Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.

Genetic surfactant dysfunction disorders are caused by mutations in genes encoding proteins critical for the production and function of pulmonary surfactant. These rare disorders may produce familial or sporadic lung disease, with clinical presentations ranging from neonatal respiratory failure to childhood- or adult-onset interstitial lung disease. An overview of these disorders is presented in the table.. Interstitial lung diseases in children until recently were categorized by their histologic appearance in a manner similar to that used for adult forms of interstitial lung disease (ILD). In children, the lung histopathology findings associated with desquamative interstitial pneumonitis (DIP) are now known to often result from genetic mechanisms that disrupt normal surfactant production and metabolism. By contrast, DIP in adults is considered to represent a distinct type of ILD, which is strongly associated with cigarette smoking and carries a relatively favorable prognosis [1]. These genetic disorders also result in histopathologic patterns other than DIP, including findings of pulmonary alveolar proteinosis and chronic pneumonitis of infancy. An understanding of the pathogenesis of these disorders permits a mechanistic classification as genetic surfactant dysfunction disorders instead of their previous classification based upon histologic appearance.

A displaced fibular head can create tightness, pain, and even numbness or tingling along the outside of your knee and down your leg. This most often occurs after a modest hyperextension knee injury, such as landing on one leg after jumping. If you have lingering knee pain and are searching for an answer, try this move

An abscess is a tender mass generally surrounded by a colored area from pink to deep red. Abscesses are often easy to feel by touching. The middle of an abscess is full of pus and debris. Painful and warm to touch, abscesses can show up any place on your body. The most common sites are in your armpits (axillae), areas around your anus and vagina(Bartholin gland abscess), the base of your spine (pilonidal abscess), around a tooth (dental abscess), and in your groin. Inflammation around a hair follicle can also lead to the formation of an abscess, which is called a boil (furuncle).

Aortic valve replacement is a procedure in which a patient's failing aortic valve is replaced with an artificial heart valve. The aortic valve can be affected by a range of diseases; the valve can either become leaky (aortic insufficiency / regurgitation) or partially blocked (aortic stenosis).

all pregnant women be screened for Chlamydia at the first prenatal visit. Women under age 25 and those at increased risk for chlamydia! Infection should have repeat testing in the third trimester. Chlamydia endometritis during pregnancy can lead to chorioamnionitis and premature delivery of the fetus. Untreated infection during pregnancy can also lead to conjunctivitis (ophthalmia neonatorum) and pneumonia in the newborn baby

The eyelid is injected with a local anesthetic, a clamp is put on the eyelid, then the eyelid is turned over, an incision is made on the inside of the eyelid, and the chalazion is drained and scraped out with a curette. A scar on the upper lid can cause discomfort as some patients feel the scar as they blink.

The preferred route of access for temporary transvenous pacing is the internal jugular vein followed by subclavian and femoral veins. However, all the major venous access sites (internal and external jugular, subclavian, brachial, femoral) have been used and each is associated with particular problems.

Peritoneal dialysis (per-ih-toe-NEE-ul die-AL-uh-sis) is a way to remove waste products from your blood when your kidneys can no longer do the job adequately. A cleansing fluid flows through a tube (catheter) into part of your abdomen and filters waste products from your blood. After a prescribed period of time, the fluid with filtered waste products flows out of your abdomen and is discarded. Peritoneal dialysis differs from hemodialysis, a more commonly used blood-filtering procedure. With peritoneal dialysis, you can give yourself treatments at home, at work or while traveling. Peritoneal dialysis isn't an option for everyone wit

Pyogenic liver abscess Email this page to a friend Email this page to a friend Facebook Twitter Google+ Pyogenic liver abscess is a pus-filled area in the liver. Causes There are many potential causes of liver abscesses, including: Abdominal infection, such as appendicitis, diverticulitis, or a perforated bowel Infection in the blood Infection of the bile draining tubes Recent endoscopy of the bile draining tubes Trauma that damages the liver The most common bacteria that cause liver abscesses are: Escherichia coli Bacteroides Enterococcus Klebsiella pneumoniae Staphylococcus aureus Streptococcus In most cases, more than one type of bacteria is found.

Tension pneumothorax describes the progressive accumulation of air in the pleural cavity (normally a potential space) through a defect in the visceral pleura. This leads to positive pressure being maintained and increasing throughout the respiratory cycle causing vessels within the mediastinum to be compressed with catastrophic consequences if left untreated. Clinical signs include hypoxia, hypotension, tachycardia, reduced breath sounds and hyper resonance ipsilaterally, with tracheal deviation (away from the affected side) and distended neck veins being late clinical signs.

Inner Workings tells the story of the ceaseless pull of the human heart — even as it works against the very stoic realism of the brain.

A C-reactive protein (CRP) test is a blood test that measures the amount of a protein called C-reactive protein in your blood. C-reactive protein measures general levels of inflammation in your body. High levels of CRP are caused by infections and many long-term diseases.
