This is a surgery showing the removal of a large exostosis. Exostoses are bony growths in the ear canal from chronic exposure to cold water/air, most commonly from surfing. This patient had growths in both ears, which were completely obstructing the ear canals. This patient had a single exostosis that was blocking this side (the right side).

Heart failure can be ongoing (chronic), or your condition may start suddenly (acute). Heart failure signs and symptoms may include: Shortness of breath (dyspnea) when you exert yourself or when you lie down Fatigue and weakness Swelling (edema) in your legs, ankles and feet Rapid or irregular heartbeat Reduced ability to exercise Persistent cough or wheezing with white or pink blood-tinged phlegm Increased need to urinate at night Swelling of your abdomen (ascites) Sudden weight gain from fluid retention Lack of appetite and nausea Difficulty concentrating or decreased alertness Sudden, severe shortness of breath and coughing up pink, foamy mucus Chest pain if your heart failure is caused by a heart attack

Not all conditions that lead to heart failure can be reversed, but treatments can improve the signs and symptoms of heart failure and help you live longer. Lifestyle changes — such as exercising, reducing salt in your diet, managing stress and losing weight — can improve your quality of life.

Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.

A chronic cough is a cough that lasts eight weeks or longer in adults, or four weeks in children. A chronic cough is more than just an annoyance. A chronic cough can interrupt your sleep and leave you feeling exhausted. Severe cases of chronic cough can cause vomiting, lightheadedness and even rib fractures. While it can sometimes be difficult to pinpoint the problem that's triggering a chronic cough, the most common causes are tobacco use, postnasal drip, asthma and acid reflux. Fortunately, chronic cough typically disappears once the underlying problem is treated.

A good starting point for any scientist in any field is to recognize that there is much we do not know. We do not know, for example, why there is more matter than antimatter in the universe. We do not know very well how the evolution of the dinosaurs filtered out. And, perhaps most surprising of all is that we do not know very well how many organs the human body has or what all its functions are.

Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly over a few hours or a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care. Acute kidney failure can be fatal and requires intensive treatment. However, acute kidney failure may be reversible. If you're otherwise in good health, you may recover normal or nearly normal kidney function
