Coronary Artery Disease

noreply@blogger.com (Anonymous) — Sun, 20 Jul 2014 14:51:00 +0000

Bateeilee blog admin will share Coronary Artery Disease. Coronary artery disease (CAD) is a condition in which plaques build up in the walls of the coronary arteries (the vessels that supply blood to the heart muscle). These plaques can gradually obstruct the artery, or they can suddenly rupture, causing a more acute obstruction. Because the heart muscle requires a continuous supply of oxygen and nutrients to survive, obstruction of a coronary artery rapidly leads to significant problems.

CAD is caused by atherosclerosis. Atherosclerosis is a chronic, progressive disorder of the arteries in which deposits of cholesterol, calcium, and abnormal cells (that is, plaques) build up on the inner lining of the arteries.

These plaques can cause a gradual but progressive narrowing of the artery, and as a result, blood flow through the artery becomes more difficult. When the obstruction becomes large enough, the patient may experience angina.

"Angina" refers to the symptoms a patient experiences any time the heart muscle is not getting enough blood flow through the coronary arteries. Angina is usually felt as a discomfort (often a pressure-like pain) in or around the chest, shoulders, neck or arms.

"Stable angina" is angina that occurs in a nearly predictable fashion, for instance, with exertion or after a big meal. Stable angina generally means that a plaque has become large enough to produce a partial obstruction of a coronary artery.

When a person with stable angina is at rest, the partially blocked artery is able to meet the needs of the heart muscle. But when that person exercises, (or has some other stress that makes the heart work harder), the obstruction prevents an adequate increse in blood flow to the heart muscle, and angina occurs. So stable angina usually means there that there is a significant plaque in a coronary artery that is partially obstructing the flow of blood.

In addition to causing obstruction by a gradual increase in their size, plaques are also subject to sudden rupture, which can produce a very sudden obstruction. The medical conditions caused by the rupture of a plaque are referred to as Acute Coronary Syndrome (ACS). ACS is always a medical emergency.

“Unstable angina” is one type of ACS. Unstable angina occurs when a plaque has partially ruptured, causing a sudden worsening of the blockage in the artery. In contrast to stable angina, symptoms in unstable angina occur unpredictably, (that is, they are not particularly related to exertion or stress), and notably, tend to occur at rest. (Another name for unstable angina is "rest angina.") Patients with unstable angina are at high risk of developing a total occlusion of the coronary artery, leading to a myocardial infarction.

Myocardial infarction, or heart attack, is a more dire form of ACS. Here, the ruptured plaque causes a total (or near total) occlusion of the coronary artery, so that the heart muscle supplied by that artery dies. A heart attack, therefore, is death of heart muscle. The seriousness of a myocardial infarction depend largely on how much heart muscle has died. A small heart attack is one in which only a small portion of the heart muscle dies. A large heart attack is one in which a large portion of heart muscle dies.

If a patient receives medical attention within a few hours of the onset of a heart attack, the size of the heart attack can be greatly reduced by administering “clot-busting drugs," or by performing an immediate angioplasty (and most often, stenting) to open up the blocked artery.

After surviving a heart attack, the patient is still at risk. Further heart attacks are possible if more plaques are present in the coronary arteries. Also, depending on the amount of heart muscle that has been damaged, the patient can develop heart failure. Furthermore, damaged heart muscle can cause a permanent instability in the heart's electrical system, which can lead to sudden cardiac arrest. So after a heart attack, all of these risks need to be carefully evaluated, and steps need to be taken to reduce each of these risks to the greatest extent possible. Here is more information on reducing risk after surviving a heart attack.

The best way to deal with coronary artery disease, of course, is to prevent it. All of us should do everything we can to reduce our CAD risk factors.

For those who already have CAD, reducing these same risk factors becomes even more important, in order to slow the progression of the disease. In addition, several avenues are available for treating CAD, including drug therapy, surgical therapy, and angioplasty and stenting. The treatment of CAD always needs to be individualized, and optimal therapy depends on careful consideration of all the options, by both the doctor and the patient.

What Is Peripheral Artery Disease?

noreply@blogger.com (Anonymous) — Sun, 20 Jul 2014 14:42:00 +0000

Bateeilee blog admin will post What Is Peripheral Artery Disease?. Peripheral artery disease (PAD) is a condition in which one or more of the arteries supplying blood to the legs (or arms) becomes blocked or partially blocked, usually because of atherosclerosis. If the blood flow to the limbs is no longer sufficient to keep up with the demand, a person with PAD may experience symptoms.

What Are the Symptoms of PAD?

The most common symptom of PAD is "claudication." Claudication is pain, cramping or discomfort - which can vary from merely annoying to quite severe - that occurs in the affected limb. Typically, claudication occurs during exercise, and is relieved by rest.

Since PAD most commonly affects the legs, claudication most typically manifests as leg pain when walking. Depending on where in the leg artery the blockage is located, leg claudication can affect the foot, calf, thigh or buttocks. People who have PAD in one of the arteries that supply the upper extremities can experience claudication in the arm or shoulder; and some can even experience neurological symptoms during arm exercise, a condition called "subclavian steal syndrome."

Sometimes PAD will cause persistent claudication even at rest. Resting claudication often means that the arterial blockage is relatively severe, and the affected limb is not receiving sufficient bloodflow even at rest.
Because claudication does not always follow the typical pattern - that is, pain during exertion, with relief during rest - the diagnosis of PAD should be considered any time a person over 50 years of age, who has risk factors for atherosclerosis, experiences unexplained pain in the arms or legs.

Very severe PAD can lead to ulceration and even gangrene of the affected limb.

What Causes PAD?

In the large majority of cases, PAD is caused by atherosclerosis. This means that the same kinds of risk factors that produce coronary artery disease (CAD) - especially elevated cholesterol levels, smoking, hypertension and diabetes - also produce PAD. In fact, because PAD and CAD are caused by the same disease process, when PAD is diagnosed, very often it means that CAD is also present.

More rarely, PAD can be seen in people who do not have atherosclerosis. For instance, PAD can be caused by trauma to the limbs, exposure to radiation, and certain drugs (the ergotamine drugs) used to treat migraine headaches.

How Is PAD Diagnosed?

PAD can be diagnosed with non-invasive testing. In some cases, PAD can be detected by physical examination, when a reduced pulse is noticed in the affected limb. More often, however, one of several specific tests is required to diagnose PAD.

Diagnosing PAD in the legs can be done using the "ankle-brachial index," or ABI, in which the blood pressure is measured and compared in the ankle and the arm. A low ABI index indicates a reduced blood pressure in a leg artery, indicating that PAD is present.

"Plethysmography" is another technique used for diagnosing PAD. With this test, air is pumped into a series of cuffs placed along the leg, and the pulse pressure of the artery beneath each cuff is estimated. A blockage somewhere in the artery will result in a reduced pulse pressure beyond the area of blockage.

"Duplex ultrasonography" is a special ultrasound test which provides an estimate of blood flow at various levels within an artery. A sudden drop in blood flow suggests a partial blockage at the area of the drop.
If your doctor suspects PAD, one or more of these non-invasive tests is usually sufficient to make a diagnosis. Today, the ABI is the test used most commonly.

How Is PAD Treated?

While mild or moderate PAD can be treated with medication and lifestyle changes, more severe cases often require bypass surgery or angioplasty to relieve the blockages.

What is Atherosclerosis?

noreply@blogger.com (Anonymous) — Sun, 20 Jul 2014 14:35:00 +0000

Bateeilee blog admin will share What is Atherosclerosis?. Atherosclerosis is a chronic, progressive disease in which plaques (consisting of deposits of cholesterol and other lipids, calcium, and large inflammatory cells called macrophages) build up in the walls of the arteries.

These plaques can cause several problems. First, plaques can protrude into the artery, eventually causing a partial or complete obstruction to blood flow. Second, plaques can suddenly rupture, causing a thrombus (blood clot) to form, leading to sudden occlusion of the artery. (This condition is called arterial thrombosis.) Third, plaques can weaken the wall of the artery causing a ballooning out of the artery to form what is called an aneurysm. The rupturing of an aneurysm often produces severe internal bleeding.

What causes atherosclerosis?

The fundamental underlying cause of atherosclerosis has not been fully established. However, many factors that contribute to atherosclerosis have been identified, including:

Genetic predisposition - the propensity for atherosclerosis clearly runs in families. Anybody whose close relatives (parents, sibs, uncles and aunts) have had atherosclerosis ought to take every opportunity to reduce their own risk factors.
Cholesterol abnormalities - high blood levels of LDL cholesterol, and low levels of HDL cholesterol, are associated with atherosclerosis.
Hypertension
Smoking
Sedentary lifestyle
Obesity, especially abdominal obesity
Diabetes

In Western cultures, arteries commonly show early changes of atherosclerosis even in childhood and adolescence. This is a disease that develops over a period of decades before it ever begins to produce symptoms.

Which arteries are affected?

Atherosclerosis commonly affects the coronary arteries, leading to angina and myocardial infarction (heart attack); the cerebrovascular circulation (brain arteries), leading to stroke; the renal arteries, leading to kidney disease; the aorta, leading to aortic aneurysm; and the blood vessels of the arms and (especially) the legs, leading to claudication, ulceration, skin changes, and slow-healing.

In the United States, atherosclerosis causes more death and disability than any other disease.

Medical Treatment for Angina

noreply@blogger.com (Anonymous) — Fri, 18 Jul 2014 19:59:00 +0000

Bateeilee blog admin will share Medical Treatment for Angina. If you have coronary artery disease (CAD), you can develop cardiac symptoms for two general reasons. First, it is possible to have acute coronary syndrome (ACS), which is a sudden deterioration caused by the formation of a blood clot within a coronary artery. ACS causes unstable angina and myocardial infarctions (heart attacks).

Second, you can have angina caused by the gradual development of partial blockages in a coronary artery. In this case, you can experience episodes of cardiac ischemia during periods of cardiac stress (such as exercise), when your heart muscle is demanding more oxygen than a partially blocked coronary artery can provide. The oxygen-starved (ischemic) heart muscle often causes the painful or uncomfortable sensation which we refer to as angina. Because this kind of angina is due to a blockage that is changing only gradually, and because the angina it produces occurs relatively predictably (that is, during a certain amount of exercise), we call it stable angina.

There are two general approaches to treating stable angina. The first approach is to use so-called "invasive therapy" -- that is, to use either bypass surgery or angioplasty and stenting to relieve specific blockages. You can read here about bypass surgery, angioplasty, and stents.

The second approach is to use medical therapies, also referred to as "non-invasive" therapies, including drugs and other non-surgical approaches. Medical therapies tend to work by reducing the "oxygen demand" of the heart muscle, that is, to reduce the amount of oxygen the heart muscle requires, so that even a partially blocked can deliver an adequate amount. The rest of this article reviews medical therapies for stable angina.

Drug Therapy For Stable Angina

Three categories of drugs are commonly used to lower the oxygen demand of the heart muscle, and to treat or prevent episodes of stable angina. These categories are nitrates, beta blockers, and calcium channel blockers. A few new drugs that are not in any of these categories are also being developed.
Nitrates: Nitrates cause dilation of blood vessels, which reduces stress on the heart muscle, thereby reducing the cardiac demand for oxygen.

Beta blockers: Beta blockers reduce the effect of adrenaline on the heart muscle, which reduces the heart rate and the force of heart muscle contraction, thus reducing the oxygen demand of the heart. These drugs also improve survival in some patients with CAD.

Calcium blockers: Calcium blockers reduce the influx of calcium into the heart muscle, also into the smooth muscle of blood vessels. This results in blood vessel dilation, lowers heart rate, and reduces the forcefulness of the heart beat -- all of which lower the oxygen demand of the heart.

Other anti-anginal drugs: Ranexa (ranolazine) is a new type of anti-angina drug that appears to work by blocking what is called the "late sodium channel" in heart cells which are suffering from ischemia. Blocking this sodium channel improves the metabolism in ischemic heart cells, reducing damage to the heart muscle, and also reducing angina symptoms.

How are these drugs used? In general, if you have angina your doctor usually will first give you a beta blocker, and also nitroglycerin (one of the nitrates) to treat any acute episodes you may have. If you still have episodes of angina, your doctor may next give you either a long-acting form of nitrate therapy or a calcium channel blocker (or both). Ranexa, being a new drug, is usually given as a third or fourth drug when necessary -- but some cardiologists have found it to be useful when added earlier. Finally, almost all patients with angina should be placed on aspirin, 81 to 325 mg/day. If your doctor does not do this, you should bring it up yourself.

Other Non-invasive Therapy for Stable Angina

Exercise therapy: Exercise training is an effective method of reducing episodes of angina in people with stable angina. Chronic, low-intensity aerobic exercise (for instance, walking or cycling) "trains" your cardiovascular system and the skeletal muscles to become more efficient. This means you will be able to maintain higher levels of exercise without experiencing angina.

If you have CAD you should usually begin an exercise program under medical supervision. Your doctor may perform a formal stress test to measure your exercise capacity, and to evaluate the level of exercise that begins to produce cardiac ischemia. You will then be given an exercise "prescription," advising you to maintain a heart rate during aerobic exercise that is 60% to 75% of your highest "safe" heart rate, as measured during the exercise test.

A program of aerobic exercise has many benefits in addition to reducing episodes of angina, including promoting weight control, improving vascular health, improving muscle and joint strength, and creating a better mindset for achieving other favorable lifestyle modifications such as diet control and smoking cessation.

Enhanced external counterpulsation (EECP): EECP is a unique treatment for angina that can be quite effective in some patients, but which most cardiologists studiously ignore.

What is Unstable Angina?

noreply@blogger.com (Anonymous) — Fri, 18 Jul 2014 19:50:00 +0000

Bateeilee blogs admin will share What is Unstable Angina?. Unstable angina is a pattern of angina that occurs randomly or unpredictably, and is unrelated to any obvious trigger (such as physical exertion or emotional stress). Unstable angina is a form of Acute Coronary Syndrome (ACS), and like all ACS, unstable angina should be considered a medical emergency.

What is Unstable Angina?

Angina is considered to be "unstable" when it no longer follows the predictable patterns typical of "stable angina."

Unstable angina is called "unstable" for two reasons.
First, in contrast to stable angina, symptoms occur in a more random and unpredictable fashion. While in stable angina, symptoms typically are brought on by exertion, fatigue, anger, or some other form of stress, in unstable angina symptoms can (and often do) occur without any apparent trigger. In fact, unstable angina often occurs at rest, and can even wake people from a restful sleep. Furthermore, in unstable angina, the symptoms often persist for more than just a few minutes, and nitroglycerin often fails to relieve the pain. So: unstable angina is "unstable" because symptoms may occur more frequently than usual, without any discernible trigger, and may persist for a long time.

Second, and more importantly, unstable angina is "unstable" because, as with all forms of ACS, it is most often caused by the actual rupture of a plaque in a coronary artery. In unstable angina, the ruptured plaque, and the blood clot that is almost always associated with the rupture, are producing partial blockage of the artery. The partial blockage may take a "stuttering" pattern (as the blood clot grows and shrinks), producing angina that comes and goes in an unpredictable fashion. If the clot should cause complete obstruction of the artery (which happens commonly), the heart muscle supplied by that affected artery is in grave danger of sustaining irreversible damage. In other words, the imminent risk of a complete myocardial infarction is very high in unstable angina. Obviously, such a condition is quite "unstable," and for this reason is a medical emergency.

When Should You Suspect You Might have Unstable Angina?

Anybody with a history of coronary artery disease should suspect unstable angina if their angina begins to occur at lower levels of physical exertion than normal, if it occurs at rest, if it persists longer than usual, if it is more difficult to relieve with nitroglycerin, or especially if it wakes them up at night.

People without any history of coronary artery disease can also develop unstable angina. Unfortunately these people seem to be at higher risk of a heart attack because, unfortunately, they often don’t recognize the symptoms as being angina. The classic symptoms of angina include chest pressure or pain, sometimes squeezing or “heavy” in character, often radiating to the jaw or left arm. Unfortunately, many patients with angina do not have classic symptoms. Their discomfort may be very mild, and may be localized to the back, abdomen, shoulders, or either or both arms. Nausea, breathlessness, or merely a feeling of heartburn may be the only symptom. What this means, essentially, is that anyone middle aged or older, especially anyone with one or more risk factors for coronary artery disease, should be alert to symptoms that might represent angina.

If you think there is any possibility you might have unstable angina, you need to go to your doctor, or to an emergency room, immediately.

How Is Unstable Angina Diagnosed?

Symptoms are critically important in making the diagnosis of unstable angina, or indeed, any form of ACS. In particular, if you have one or more of the following three symptoms, your doctor should take that as a strong clue that one type or another of ACS is occurring:

Angina at rest, especially if it lasts more than 20 minutes at a time
New onset angina that markedly limits your ability to engage in physical activity
An increase in prior stable angina, with episodes that are more frequent, longer lasting, or occur with less exertion than previously

Once your doctor suspects ACS, he should immediately get an ECG and blood tests for cardiac enzyme testing. If the portion of the ECG known as "ST segments" are elevated (which indicates that the artery is completely blocked), and the cardiac enzymes are increased (which indicates cardiac cell damage), a "large" myocardial infarction (MI) is diagnosed (also called an "ST-segment elevation MI," or STEMI).

If the ST segments are not elevated (indicating that the artery is not completely blocked), but the cardiac enzymes are increased (indicating that cell damage is present), a "smaller" MI is diagnosed (also called a "non-ST segment MI," or NSTEMI).

If the ST segments are not elevated and the enzymes are normal (meaning the artery is not completely blocked and no cell damage is present), unstable angina is diagnosed.

Notably, unstable angina and NSTEMI are similar conditions. In each condition, a plaque rupture has occurred in a coronary artery, but the artery is not completely blocked so at least some blood flow remains. In both of these conditions, the symptoms of unstable angina are present. The only difference is that in an NSTEMI enough heart cell damage has occurred to produce an increase in cardiac enzymes. Because these two conditions are so similar, their treatment is identical.

What Is the Treatment For Unstable Angina (and NSTEMI)?

If you have either unstable angina or NSTEMI, you will be treated with one of two general approaches: a) treat aggressively with drugs to stabilize the condition, then evaluate non-invasively, or b) treat aggressively with drugs to stabilize the condition, and schedule early invasive intervention (generally, angioplasty and stenting).

What's Unstable Angina or Stable Angina?

noreply@blogger.com (Anonymous) — Fri, 18 Jul 2014 19:40:00 +0000

Bateeilee blog admin will share about What's Unstable Angina or Stable Angina?. Angina is the name given to the symptoms (usually chest pain or chest discomfort) produced when the heart muscle is in a state of ischemia - that is, when the heart muscle is not getting enough blood supply. In unstable angina, ischemia occurs unpredictably and suddenly, usually because a blood clot has suddenly formed within a coronary artery, temporarily limiting blood flow to the heart muscle.

Unstable angina is often exacerbated by the formation of temporary blood clots within the coronary arteries. If the blood clots persist, a heart attack can occur. It's not surprising, then, that unstable angina often occurs before a heart attack, and should be treated aggressively.

Stable Angina is the name given to the symptoms (usually chest pain or chest discomfort) produced when the heart muscle is in a state of ischemia - that is, when the heart muscle is not getting enough blood supply. Stable angina occurs when there is a partial blockage in a coronary artery that limits the maximum blood flow to the heart muscle.

Patients with stable angina usually have no symptoms during rest or with mild activity, since blood flow to the heart muscle is adequate under these conditions. However, during periods of exercise or other conditions of stress in which the heart muscle requires more oxygen, the partial blockage prevents an adequate increase in blood flow. This lack of sufficient blood flow under these circumstances produces ischemia, thus leading to angina.

This condition is called "stable" angina because the symptoms occur in a predictable fashion - that is, they occur only under conditions such as exercise or other stresses that require the heart to work harder.
In contrast, in unstable angina symptoms occur unpredictably, most often at rest.

How the Blood Clots?

noreply@blogger.com (Anonymous) — Fri, 18 Jul 2014 19:29:00 +0000

Bateeilee blogs admin will post How the Blood Clots?. The clotting mechanism is one of the most important and complex of physiologic systems. Blood must flow freely through the blood vessels in order to sustain life. But if a blood vessel is traumatized, the blood must clot to prevent life from flowing away. Thus, the blood must provide a system that can be activated instantaneously – and that can be contained locally – to stop the flow of blood. This system is called the clotting mechanism.

To treat or prevent abnormal blood clotting, doctors must understand the multifaceted aspects of the clotting mechanism. The following explanation is greatly simplified, but is designed to provide a basic understanding of how the many drugs used to treat clotting problems work, and some basis for assessing the treatments your doctor may prescribe for you.

How does the blood clot?

There are two major facets of the clotting mechanism – the platelets, and the thrombin system. The platelets are tiny cellular elements, made in the bone marrow, that travel in the bloodstream waiting for a bleeding problem to develop. When bleeding occurs, chemical reactions change the surface of the platelet to make it “sticky.” Sticky platelets are said to have become “activated.” These activated platelets begin adhering to the wall of the blood vessel at the site of bleeding, and within a few minutes they form what is called a “white clot.” (A clump of platelets appears white to the naked eye.)

The thrombin system consists of several blood proteins that, when bleeding occurs, become activated. The activated clotting proteins engage in a cascade of chemical reactions that finally produce a substance called fibrin. Fibrin can be thought of as a long, sticky string. Fibrin strands stick to the exposed vessel wall, clumping together and forming a web-like complex of strands. Red blood cells become caught up in the web, and a “red clot” forms.

A mature blood clot consists of both platelets and fibrin strands. The strands of fibrin bind the platelets together, and “tighten” the clot to make it stable.

In arteries, the primary clotting mechanism depends on platelets. In veins, the primary clotting mechanism depends on the thrombin system. But in reality, both platelets and thrombin are involved, to one degree or another, in all blood clotting.

How the Blood Clots - using a coronary artery as an example.

Figure 1. A coronary artery is shown that has an atherosclerotic plaque ("AP") partially occluding the lumen (opening) of the artery. Platelets within the blood are shown ("P"). The flow of blood through the artery is indicated by the long arrow. The patient with this artery likely has stable angina.

Figure 2. The atherosclerotic plaque has developed an ulcer ("U").

Figure 3. The platelets have been activated (i.e., made "sticky") by their exposure to the ulcerated plaque. They begin to aggregate (to stick) to the surface of the ulcer.

Figure 4. The thrombin system has been activated (also by exposure of the blood to the surface of the ulcer), and fibrin strands begin to form, connecting the aggregated platelets, and drawing them together.

Figure 5. A mature clot is now present, superimposed on the atherosclerotic plaque. This clot makes the partial obstruction of the coronary artery substantially worse. The arrow indicates the increased sluggishness and turbulence of blood flow through the artery. This patient most likely now has unstable angina, and if blood flow is sluggish enough, some of the heart cells supplied by this artery may die.

If the artery becomes totally occluded by a clot, a classic heart attack (myocardial infarction) will occur.

How can the clotting mechanism produce problems?

The clotting system, like all complex physiologic systems, can produce problems. Blood clots forming on atherosclerotic plaques in the arteries are the major cause of heart attack and stroke. Blood clots forming in the veins of the legs produce a painful condition called phlebitis, and when these venous blood clots break off (“embolize”) they move into the lungs and produce a dangerous condition called pulmonary embolus.

How can abnormal blood clotting be treated?

Drugs used for preventing or treating abnormal blood clotting can be aimed either at the platelets, or at the thrombin system. While they all have their own profile of side effects, one side effect common to all these drugs is excess bleeding. They must all be used with appropriate precautions.

Drugs aimed at the thrombin system.

Drugs that prevent further fibrin from forming. These drugs, which inhibit one or more of the proteins involved in the thrombin clotting system, are used for both arterial and venous clotting problems. Heparin. Heparin is an intravenous drug that has an immediate (within seconds) inhibitory effect on the thrombin system. Its dosage can be adjusted frequently, following the PTT blood test (the partial thromboplastin time) to achieve the desired effect.

Low molecular weight heparin: enoxaparin, dalteparin. LMWH is a “purified” derivative of heparin. Its major advantages are that it can be given as a skin injection (which almost anyone can learn to do in a few minutes), and does not need to be closely monitored with blood tests. Thus, unlike heparin, LMWH can be administered safely on an outpatient basis.

Coumadin. Coumadin is an oral anti-thrombin drug that can be taken chronically. The dose must be carefully monitored by following the prothrombin time (PT), a blood test.

Drugs that “dissolve” fibrin – the fibrinolytic drugs. These powerful drugs actually dissolve fibrin strands that have already formed.

TPA, streptokinase, urokinase. These are the intravenous drugs that are administered acutely during the first few hours of an acute heart attack or stroke, to attempt to re-open an occluded artery, and prevent permanent tissue damage.

Drugs aimed at platelets.

These three groups of drugs, in one way or another, reduce the “stickiness” of platelets. They are used most commonly in preventing arterial clots from forming. Aspirin and diypyramidole. These drugs have a modest effect on platelet “stickiness,” but have few important side effects.

Ticlopidine (Ticlid) and clopidrogel (Plavix). These drugs are somewhat more powerful than the first group, but can be poorly tolerated and can have important side effects. They are generally used in patients who need, but cannot tolerate, aspirin.

IIb/IIIa inhibitors: abciximab (Reopro), eptifabitide (Integrilin), tirofiban (Aggrastat). The IIb/IIIa inhibitors are the most powerful group of platelet inhibitors. They inhibit a receptor on the surface of platelets (the so-called IIb/IIIa receptor) that is essential for platelet stickiness. Their chief usage is to prevent acute clotting after interventional procedures (such as angioplasty and stent placement), and in patients with acute coronary artery syndromes, such as unstable angina. These drugs are very expensive and (in general) must be given intravenously.

Preventing Acute Coronary Syndrome

noreply@blogger.com (Anonymous) — Fri, 18 Jul 2014 19:21:00 +0000

Bateeilee blog admin will share Preventing Acute Coronary Syndrome. Preventing acute coronary syndrome - ACS - should be one of your chief concerns if you have been told you have coronary artery disease (CAD).

Acute coronary syndrome (ACS) occurs when a blood clot suddenly forms within a coronary artery. This usually happens when a plaque ruptures in the wall of the artery. The blood clot produces a sudden blockage of the artery, leading to ischemia (insufficient blood flow to the heart muscle).

The severity of ACS syndrome depends on whether the blood clot completely or only partially blocks the artery, and how long the clot lasts. (The body's protective mechanisms try to dissolve blood clots that form within blood vessels. Read more about how the blood clots here.) Clots that completely block an artery often cause myocardial infarction or even sudden death. Clots that only partially block an artery, or that persist for only a few minutes, produce unstable angina. In either case, ACS is a medical emergency.

Anyone with CAD can develop ACS. So everyone with CAD should take appropriate steps to reduce the risk of ACS. These preventative actions include steps to lower the risk of plaque rupture, and steps to reduce the risk of large or persistent blood clots if a rupture occurs.

Accordingly, if you have CAD you should do the following things:

Stop smoking. You should think of smoking as a technique for actively irritating plaques within your coronary arteries. Even one cigarette can acutely increase the risk of ACS for up to a day or two. And when you quit smoking, your risk of ACS drops substantially within a few days.
Ask your doctor about statin therapy. Statins can help to stabilize plaques to help keep them from rupturing. Statins also improve the function of the lining of arteries, reduce inflammation, and reduce blood clot formation -- all of which can help to prevent ACS.
Make sure your blood pressure is normal blood pressure. High blood pressure increases the risk of plaque rupture.
Ask your doctor about taking beta blockers. Beta blockers can help prevent plaque rupture by limiting the effect of stress and exertion on the blood vessels.
Make sure your cholesterol measurements are adequate. High LDL cholesterol and low HDL cholesterol levels are thought to increase the risk of plaque rupture.
Ask your doctor about taking aspirin. Aspirin therapy reduces the "stickiness" of blood platelets, and can reduce blood clot formation when plaque rupture occurs.

Taking these steps will go a long way toward preventing ACS.

What Is Acute Coronary Syndrome - ACS

noreply@blogger.com (Anonymous) — Fri, 18 Jul 2014 19:09:00 +0000

Bateeilee blog admin will share What Is Acute Coronary Syndrome - ACS. Coronary artery disease (CAD) produces two broad categories of clinical syndromes - stable angina, and Acute Coronary Syndrome (ACS). If you have CAD, you probably know all about stable angina. But chances are, you don't know much about ACS. You need to know about ACS, though, because it is extremely important.

What is ACS?

ASC occurs when a blood clot suddenly forms within a coronary artery, usually due to the acute rupture of a plaque. Plaque rupture can occur at any time, and often completely without warning. The blood clot will often completely stop or significantly reduce the flow of blood to the heart muscle, and is considered a medical emergency. Any plaque can rupture, even small ones. This is why you will often hear of people who have a myocardial infarction (MI), or heart attack, shortly after being told their CAD is "insignificant."

Symptoms of ACS

The symptoms of ACS are similar to those of stable angina (i.e., chest pain or discomfort), but are often much more intense and persistent. The chest pain in ACS is often accompanied by other disturbing symptoms such as sweating, dizziness, nausea, extreme anxiety, and what is often described as a "feeling of impending doom." The chest pain is often untouched by nitroglycerin (which usually relieves stable angina). On the other hand, some people who have ACS will have only mild symptoms, or will fail to notice any symptoms at all - at least initially. Unfortunately, the permanent heart damage that often results from ACS will, sooner or later, produce symptoms.

The Three General Types of ACS.

Cardiologists divide ACS into three distinct clinical patterns. Two of them represent different forms of MI, and one represents a particularly severe form of angina, called "unstable angina." All three are caused by acute blood clots in the coronary arteries.

If the blood clot persists for more than just a few minutes, some of the heart muscle cells begin to die. The death of heart muscle is what defines an MI. There are two types of MI, based on the pattern that appears on the ECG.
- "ST-Elevation myocardial infarction" (or STEMI, so named because the "ST segment" on the ECG appears "elevated"), occurs when a coronary artery is completely blocked, so that a large proportion of the heart muscle being supplied by that artery is becoming damaged.
- Non-ST-Elevation myocardial infarction (or NSTEMI, in which the "ST segment" is not elevated), occurs when the blockage in the coronary artery is not complete, so that a relatively small proportion of heart muscle is becoming damaged.
Sometimes the blood clot that occurs in ACS does not cause any permanent heart muscle damage, either because the degree of blockage it produces is not large enough, or because the clot doesn't persist long enough, to produce cell death. (The body's protective mechanisms try to dissolve blood clots that form within blood vessels. When an ACS occurs that does not actually cause heart muscle to die, it is termed unstable angina.

Making the Right Diagnosis in ACS

To summarize, once a blood clot forms in a coronary artery, then: if a lot of heart muscle damage occurs a STEMI is diagnosed; if a "little" heart muscle damage occurs, a NSTEMI is diagnosed; if no measurable heart muscle damage occurs, unstable angina is diagnosed. Because each type of ACS is treated differently, it is important to distinguish among the three.

If you are having ACS, usually your symptoms, physical examination, medical history and cardiac risk factors will immediately steer the doctor to strongly suspect the diagnosis. From that point, he or she will quickly examine your ECG and measure your cardiac enzymes. (Cardiac enzymes are released into the bloodstream by dying heart muscle cells, so an elevation in the cardiac enzymes means that heart cell damage is occurring.) The appearance of the ECG (i.e., the presence or absence of "elevation" in the ST segments) will distinguish between STEMI and NSTEMI. And the presence or absence of elevated cardiac enzymes will distinguish between NSTEMI and unstable angina.

The Significance of ACS

The three types of ACS actually represent the spectrum of the clinical conditions that can occur when a plaque ruptures within a coronary artery. In fact, there is actually no clear line that inherently divides STEMI, NSSTEMI, and unstable angina. Where cardiologists draw the line between a STEMI and an NSTEMI, or between an NSTEMI and unstable angina, is a relatively arbitrary decision. Indeed, the definitions of these three types of ACS have changed substantially over the years, as our knowledge - specifically our ability to interpret ECGS and detect heart cell damage with enzyme tests - have improved.

The important point is that every case of ACS (no matter how it is categorized) is a medical emergency, and requires imediate medical care to try to accomplish two things: 1) to limit the heart muscle damage being done acutely by the blood clot within the coronary artery, and 2) to limit the possibility that the plaque - which has now shown itself to be unstable and prone to rupture - will rupture again.

What are the symptoms of lung cancer?

Bateeilee Blog admin will share What are the symptoms of lung cancer?. Since lung cancer survival is better the earlier it is caught, understanding some of the common symptoms of lung cancer is very important. Symptoms of lung cancer to be aware of can include:

Symptoms Related to Cancer in The Lungs

A cough that persists over time, or does not go away with treatment is a common warning sign of lung cancer. Other local symptoms that can be caused by lung cancer include:

coughing up blood (hemoptysis)
difficulty breathing – due to decreased airflow by a tumor obstructing the large airways or spread through the lungs
wheezing – caused by the interference of airflow through an airway obstructed by a tumor
pain in the chest, back, shoulder, or arm – when a lung tumor presses on nerves around the lungs
repeated lung infections such as pneumonia or bronchitis
hoarseness

No Symptoms

Roughly 25% of the time, lung cancer causes no symptoms at all. These tumors are usually found when a chest x-ray is done for another reason. Occasionally, lung cancer is found when a smoker or former smoker has a procedure to screen for lung cancer.

General Symptoms Associated With Lung Cancer

Lung cancer can sometimes present with vague symptoms. Concerns such as fatigue, unexplained weight loss, loss of appetite, and even depression can be a symptom of lung cancer as well as many other conditions. It is important to talk with your health care provider if you have any concerns such as these, especially if you have a history of smoking.

Symptoms Related to The Spread of Lung Cancer

Sometimes, the first symptoms of lung cancer are due to its spread (metastasis) to other regions in the body. With lung cancer, the most common places lung cancer spreads are to the liver, adrenal glands, brain, and bones. Symptoms commonly found include:

bone - pain in the back, ribs, or hips
brain - headaches, seizures, weakness on one side of the body, vision symptoms

Paraneoplastic Symptoms

Paraneoplastic symptoms are symptoms related to the production of hormones-like chemicals by some types of lung cancers. These often show up as unexplained findings on lab tests and can include:

low sodium levels (hyponatremia)
elevated calcium levels (hypercalcemia)
anemia
clubbing of the fingers (bulging of the fingernails)
new bone formation seen on x-rays

What Is Primary Lung Cancer?

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 14:04:00 +0000

Bateeilee blog admin will share What Is Primary Lung Cancer?. It can be confusing when doctors talk about primary and secondary lung cancer. What does it mean if your doctor says your cancer is a primary lung cancer?

A primary lung cancer is a cancer that begins in the lungs. If a primary lung cancer spreads to other regions of the body (known as metastasis) it is referred to primary lung cancer metastatic to the location of the spread. For example, a cancer that begins in the lungs and spreads to the brain would be termed “primary lung cancer metastatic to the brain.”

Cancers that begin in other regions of the body and spread to the lungs are not primary lung cancers. Sometimes they are described as “secondary cancers” but most often they are defined first by the site of the cancer followed by “metastatic to the lungs.” For example, a breast cancer that spreads to the lungs may be called “breast cancer metastatic to the lungs” or “metastatic lung cancer from the breast.” On the other hand, if someone with breast cancer developed another unrelated cancer that began in the lungs, that tumor would be considered a primary lung cancer.

A second area of cancer in the lung resulting from the spread of the first tumor would be referred to as a secondary cancer, or “primary lung cancer metastatic to another region in the lungs.”

Likewise, sometimes people who have had lung cancer develop another lung cancer at a later date. If the second tumor is a “new cancer” and unrelated to the original cancer, it would be called a primary lung cancer. If instead the second tumor was related to spread of the first tumor it may be called a secondary cancer, or more accurately, “lung cancer metastatic to another region of the lungs.”

Sometimes two separate cancers develop in the lungs at the same time. In this scenario both tumors would be considered primary lung cancers.

On rare occasions, a tumor is found in the lungs and doctors can’t be certain where it originated – the original site of the cancer is unknown. Some cancers are only discovered after they have spread to many parts of the body, including the lungs. In this case, the cancer would be called “metastatic cancer to the lungs of unknown origin.”

Is Lung Cancer Inherited?

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 13:56:00 +0000

Now Bateeilee Blog Admin will share Is Lung Cancer Inherited?. It is well known that some cancers, such as ovarian cancer and colon cancer, run in families. Even though the role of heredity in lung cancer is not as well-known, having a family history of lung cancer does increase our risk to some degree. Hereditary lung cancer is higher in women, nonsmokers and those with early onset lung cancer (lung cancer that occurs before the age of 60). Overall, it has been estimated that 1.7% of lung cancers up to the age of 68 are hereditary. Several factors are associated with hereditary lung cancer, including:

How Closely a Family Member is Related

Having a first-degree family member (parent, sibling or child) with lung cancer roughly doubles the risk of developing lung cancer. This risk is more for women and less for men and stronger in nonsmokers than smokers. Having a second-degree relative (an aunt, uncle, niece or nephew) with lung cancer raises your risk by around 30%.

Lung Cancer in Women

Smoking Status, Lung Cancer and Heredity

Smokers who develop lung cancer are less likely to have a family history than nonsmokers that develop lung cancer. That said, however, for those who have a genetic predisposition to lung cancer, smoking appears to amplify that risk.

Lung Cancer in Non-Smokers

Type of Lung Cancer and Heredity

Studies vary in the types of lung cancers that have the greatest hereditary component, but those with nonsmall cell lung cancers, especially lung adenocarcinoma are more likely to have a family history of lung cancer than those with small cell lung cancers.

A recent finding is that non-smokers with non-small cell lung cancer whose tumors have an EGFR mutation are much more likely to have a family history of lung cancer than those who have an ALK or KRAS mutation.

Race, Lung Cancer and Heredity

Blacks with first-degree relatives have a greater risk of early onset lung cancer than whites. This risk increases in smokers.

Other Cancers and Hereditary Lung Cancer

In general, having a family history of cancers other than lung cancer, does not appear to increase the risk that you will develop lung cancer. On the other side of the equation, though, those that develop more than one primary lung cancer are significantly more likely to have a genetic predisposition contributing to their cancer.

What Should I Do if I Have a Family History of Lung Cancer?

CT screening for lung cancer is an option for some people, although it's currently only recommended for those people between the ages of 55 and 74, who smoke or have quit in the past 15 years, and have at least a 30 pack-year history of smoking. Depending upon your risk factors, you and your doctor may elect to choose screening outside of these parameters. Before we despair about those genes passed on to us by Mom and Dad, we need to keep in mind that many causes of lung cancer are preventable. Quitting smoking (if you smoke), testing your home for radon, eating a healthy diet, exercising and being careful to avoid occupational causes can all help lower your risk of developing lung cancer whether you have a family history or not.

Does HPV Cause Lung Cancer?

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 13:48:00 +0000

Bateeilee Blog admin will share Does HPV Cause Lung Cancer?. In fact, in a 2008 review of 53 studies published in the journal Lung Cancer, the authors state that HPV may be the second leading cause of lung cancer after cigarette smoking, and additional research on this issue is strongly needed.

What is HPV?

HPV (human papilloma virus) is a collection of over 100 viruses that can infect humans. HPV is most often spread through skin-to-skin contact, usually sexually. Only a few of these viruses are considered the “cancer-causing” strains, most notably, HPV 16 and HPV 18, the viruses that are currently targeted in vaccines directed against HPV. Infection with a “cancer-causing” strain of HPV does not mean a person will develop cancer. In fact, most infections with HPV do not result in the development of cancer.

HPV and Cancer

HPV is now well-established as playing a role in most cases of cervical cancer, as well as many cases of vulvar, penile, and anal cancers. It is also being implicated in some cases of oral cancer, especially those occurring in young, non-smoking women.

Does HPV Infection Cause Lung Cancer?

The possibility that HPV may play a role in the development of lung cancer was first suggested in 1979. Several studies since that time have found evidence of HPV DNA in lung cancers, but this varies significantly depending on geography. In the United States, HPV DNA is found in about 20% to 25% of lung cancers. The most common strains found are HPV 16 and HPV 18, strains that are commonly found with cervical cancer as well.

Whether the presence of HPV in lung cancer indicates causation (that HPV causes lung cancer) is another question. Current thought is that HPV may be a cofactor in the development of lung cancer, that is, the virus may work together with other risk factors such as tobacco or radon to produce a cancer.

The presence of HPV in lung cancer cells is more common in females, non-smokers, and those with adenocarcinoma, a type of non-small cell lung cancer. Interestingly, those people who have evidence of HPV in lung cancer cells appear to have a better prognosis.

So what does this mean for prevention? Minimizing exposure to HPV through safe sex is a good start. Our About.com Guide to Cancer offers more tips on How To Prevent HPV.

Lung Cancer Causes

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 13:43:00 +0000

Bateeilee Blog Admin will post Lung Cancer Causes. There are many lung cancer causes, in addition to the well-known link with smoking. Lung cancer, and cancer in general, is most often a “multifactorial” disease, that is, many factors work together to cause or prevent cancer. An overview of common lung cancer causes includes:

Lifestyle

Smoking – Smoking is responsible for 87% of lung cancers.
Lack of exercise – People who engage in moderate exercise are less likely to develop lung cancer.
Unhealthful diet – A higher intake of foods, such as salads, is associated with a lower risk of developing lung cancer.
Excess alcohol – An excess intake of alcohol may raise the risk of lung cancer in smokers.

Environmental Causes

Radon – Radon is the second-leading cause of lung cancer, following smoking, and the leading cause of lung cancer in nonsmokers.
Asbestos – Exposure to asbestos is responsible for the majority of mesothelioma, a rare tumor involving the lining of the lungs.
Secondhand smoke – Secondhand smoke increases the risk of lung cancer in nonsmokers two- to- three-fold.
Air pollution – Pollution, especially in urban areas, appears to raise the risk of lung cancer.
Industrial chemicals – Several chemicals used in commerce are linked with a higher risk of lung cancer.
Radiation – Atomic bomb survivors have an elevated risk of developing lung cancer, as do those who have undergone radiation therapy for other types of cancer, such as Hodgkin’s disease.

More About Environmental Causes of Lung Cancer

Occupational Causes

Occupational exposure to carcinogens is estimated to be responsible for 13 to 29% of lung cancers in men.

More About Occupational Causes of Lung Cancer

Other Lung Diseases

People who suffer from Chronic Obstructive Pulmonary Disease (COPD) have an elevated risk of developing lung cancer irrespective of smoking history.

Genetic Causes

In general, a genetic predisposition to lung cancer does not mean someone will develop lung cancer. It means they are more likely to develop lung cancer, especially when combined with other risk factors. Research looking at the role of heredity in the development of lung cancer is in its infancy, but researchers are beginning to isolate some of the genetic changes that are associated with an increased risk of lung cancer.

More About Genetics/Family History and Lung Cancer Risk

Infectious Lung Cancer Causes

Research looking at infectious diseases as a possible cause of lung cancer is also in its infancy. Infectious agents that have been associated with lung cancer in newer studies include: chlamydia pneumoniae, human papilloma virus (HPV), and measles.

What Is Mesothelioma?

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 13:32:00 +0000

Bateeilee blog admin will share What Is Mesothelioma?. Mesothelioma is a somewhat rare cancer, with only about 2,000 new cases diagnosed in the United States each year -- but its incidence is increasing worldwide. Sadly, most cases of this disease are related to on-the-job exposure to asbestos, and could be prevented through awareness and protective measures at work. That said, in many cases, mesothelioma does not develop until decades after asbestos exposure occurs, and many people that are diagnosed today were exposed to asbestos years ago.

What Is Mesothelioma?

Mesothelioma is a cancerous (malignant) tumor that begins in the mesothelium. The mesothelium is a membrane that lines and protects the lungs, the heart, and the abdominal cavity. There are three main types of mesothelioma:

Pleural mesothelioma begins in the pleura (the lining of the lungs). This is the most common type of mesothelioma.
Peritoneal mesothelioma begins in the peritoneum (the lining of the abdominal cavity).
Pericardial mesothelioma begins in the pericardium (the lining of the heart).

Causes

Most cases of mesothelioma are because of exposure to asbestos on the job. Other causes include:

Genetic susceptibility – Some people are more likely to develop mesothelioma than others
Exposure to a particular virus – A virus called simian virus 40 (SV 40) has been linked with some cases of mesothelioma
Exposure to radiation

Symptoms

Most people with pleural mesothelioma note shortness of breath and chest pain (especially under the ribs), but other symptoms can include:

Abdominal pain and bloating (with peritoneal mesothelioma)
A persistent cough
Difficulty swallowing (dysphagia)
Unexplained weight loss
Anemia
Abnormalities in blood clotting

Diagnosis

Diagnosing mesothelioma can be difficult since there are many conditions that cause similar symptoms. Your physician will first take a careful history, especially questioning you about your employment history, and then perform a physical exam. Imaging studies are often done, and may include x-rays of your chest and abdomen, CT scans, MRI scans or PET scans.

If your doctor suspects mesothelioma, she will need to schedule a biopsy. Depending upon the location of your tumor, she may recommend a thoracoscopy or video-assisted thoracoscopy (VAT), a procedure where a tissue sample is taken from the pleura, or a peritoneoscopy, a similar procedure to obtain tissue from the abdomen. If the biopsy reveals mesothelioma, further studies are then done to determine the stage of the cancer (how advanced it is).

Stages

Mesothelioma is divided into 2 primary stages:

Localized (Stage 1) – With localized mesothelioma, the cancer is confined to the mesothelium – the pleura with pleural mesothelioma, or the peritoneum with peritoneal mesothelioma
Advanced (Stage 2, 3, and 4) – Mesothelioma is considered advanced if it has spread to the lymph nodes, or other organs including the lungs

Treatment

Depending on the size and location of your tumor, and if it has spread, treatment options may include:

Surgery – Surgery may be considered, especially if the tumor is caught at an early stage. Types of surgery include:
- Pleurectomy – With a pleurectomy, a portion of the pleura is removed
- Extrapleural pneumonectomy – A portion of the pleura is removed, as well as a portion of the pericardium (heart lining), diaphragm (muscle separating the chest and abdomen) and the lung
Chemotherapy – A combination of a chemotherapy medication and a targeted therapy may improve survival.
Radiation Therapy – Radiation therapy is occasionally used as a palliative treatment for mesothelioma, a treatment that does not cure cancer, but can make you more comfortable. It may also be used after surgery to kill any remaining cancer cells.
Clinical Trials – Several clinical trials are in progress, evaluating new ways to treat mesothelioma.

Living With Mesothelioma

On top of the heartbreak a diagnosis of cancer brings, many people with mesothelioma lack the emotional and psychosocial support that those with other forms of cancer find readily available. In addition, medico-legal battles related to asbestos exposure on-the-job can be emotionally draining. Participating in a support group, either through your cancer center, community, or online, can help you wade through the maze of treatment options, and find camaraderie in others who are living with mesothelioma.

Prevention

The most important thing you can do to prevent mesothelioma is to use appropriate precautions if you are exposed to asbestos at work. OSHA has asbestos safety standards for individuals who may be exposed on the job. If you work with asbestos, it is important to follow these guidelines to minimize your families exposure as well. Asbestos insulation in homes is usually not a problem, unless it is damaged or disturbed by remodeling projects. If you may have asbestos insulation (homes built prior to 1950) make sure to hire a contractor certified in asbestos management before you begin any home improvement projects.

Some people who have been exposed to asbestos may want to consider CT screening for lung cancer. At this time, recommendations for screening include only those people aged 55 to 74 with a 30 pack-year history of smoking. Yet studies show that some people who have been exposed to asbestos may be at an even higher risk of developing lung cancer than heavy smokers. If you've been exposed to asbestos make sure to talk to your doctor about lung cancer screening.

Lung Cancer Screening - The Issues

Occupation as a Cause of Lung Cancer

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 13:18:00 +0000

Bateeilee blog Admin will share Occupation as a Cause of Lung Cancer. Occupation as a cause of lung cancer is common. It has been estimated that 13 to 29% of lung cancers in men are secondary to on-the-job exposure to chemicals and materials that increase the risk of lung cancer. Many of these exposures are preventable through awareness, and taking appropriate precautions.

How Do I Know if Exposures at Work Can Raise My Risk?

Employers are required to provide Material Safety Data Sheets (MSDS’s) on chemicals you may be exposed to at the workplace. It is important to take the time to read these, and follow any safety recommendations that are suggested. That said, only 2% of chemicals used in commerce have been studied for carcinogenicity, that is their ability to cause cancer in humans. Though this is concerning, taking basic precautions could likely lower your risk considerably. When around chemicals, wearing gloves, ensuring proper ventilation, and using an appropriate mask are paramount. It is important to note that not all masks are created equally. Some exposures may be prevented with a simple dust mask, whereas others may require the use of a respirator to prevent a potentially toxic exposure.

What Are Some of the Exposures at Work That Could Cause Lung Cancer?

The following lists of substances and occupations that could place you at risk is far from exhaustive, but provides an overview of some of the more common exposures that are linked with lung cancer. Occupational Substances Associated With an Increased Risk of Lung Cancer

Diesel fumes
Natural fibers – asbestos, silica, wood dust
Metals – aluminum, arsenic, beryllium, cadmium, chromium, nickel
Radon
Reactive chemicals – bis(chloromethyl) ether, mustard gas, vinyl chloride
Second-hand smoke
Solvents – benzene, toluene

Occupations Associated With an Increased Risk of Lung Cancer

Asbestos workers
Bartenders
Ceramics
Chemists
Glass manufacturing
Painters
Printers
Masonry work
Metal work (iron and steel foundry work)
Sandblasting
Truck driving
Uranium mining

What Can I Do if My Employer is Not Protecting Me from Exposures?

Employers are required to provide Material Safety Data Sheets (MSDS) for each chemical you may be exposed to at work. If these have not been provided for you, or if you feel your workplace is placing you at risk, help is available. The Occupational Safety and Health Administration (OSHA) has a 24-hour access line to report unsafe work practices at 1-800-321-6742.

Where Can I Go To Find More Information on Occupational Exposures?

Several excellent sites are available that include databases on possible workplace exposures, as well as general safety information for you as an employee.

NIOSH – The National Institute of Occupational Safety and Health provides multiple databases regarding occupational safety, and includes a handy Pocket Guide to Chemical Exposures as well. NIOSH has a toll-free number for questions about occupational exposures at 1-800-356-4674.
U.S. Department of Labor. Occupational Safety and Health Administration (OSHA). OSHA provides information on laws and regulations regarding workplace safety.

Secondhand Smoke and Lung Cancer

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 13:12:00 +0000

Bateeilee blog admin will share Secondhand Smoke and Lung Cancer. The link between secondhand smoke and lung cancer has received a lot of attention lately. Laws now prohibit smoking in many public places, and TV commercials yank at our heartstrings as they depict someone that smoked mourning the loss of a non-smoking loved one. What are the facts?

Definition of Secondhand Smoke

First, what is secondhand smoke? Secondhand smoke (or environmental tobacco smoke (ETS) refers to the exposure to smoke from cigarettes another person is smoking. It is also called passive smoking or involuntary smoking. Secondhand smoke is made up of two components. “Sidestream smoke” is the smoke that is present in air from the end of a burning cigarette. “Mainstream smoke” is smoke that is exhaled by someone who is smoking after it has traveled through the lungs. Research on animals suggests that sidestream smoke may be even more dangerous than mainstream smoke, but regardless of the debate, secondhand smoke is a known human carcinogen (cancer causing substance).

The Statistics

Secondhand smoke alone is responsible for roughly 3,000 lung cancer deaths each year in the United States, and over 21,000 lung cancer deaths worldwide. Living with a smoker increases an individual’s chance of developing lung cancer by 20 to 30%.

According to U.S. Surgeon General’s report in 2006, even brief secondhand smoke exposure can cause the damage that can lead to lung cancer. Despite this risk, the report also found that nearly half of non-smoking individuals are regularly exposed to secondhand smoke. The best ventilation systems are unable to filter out secondhand smoke completely, and only smoke-free establishments are risk free.

The Culprits

There are more than 50 chemicals in tobacco smoke that are known to cause cancer. Some of the better known carcinogens include arsenic, benzene, nickel, and vinyl chloride.

How Can You Protect Yourself?

Since no level of secondhand smoke exposure is safe, insisting on a no-smoking policy in your home is an important first step in protecting yourself. Choosing public establishments, such as restaurants, that are smoke-free is helpful as well, although the availability may depend on the laws where you live. If you travel, avoiding secondhand smoke can be more difficult. Our About.com Guide to COPD, Deborah Leader has compiled ideas on protecting yourself while traveling

Secondhand Smoke and People With Lung Cancer

For someone living with lung cancer, secondhand smoke exposure can carry a double-edged sword. As an irritant to the lungs, secondhand smoke can worsen symptoms that are already present, such as coughing, but can be painful from an emotional standpoint as well. Studies tell us that lung cancer survivors experience significant distress when family members continue to smoke. If you are living with lung cancer and have family members who smoke, or, if you smoke and have a family member with lung cancer..

Does Air Pollution Cause Lung Cancer?

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 13:03:00 +0000

Bateeilee Blog Admin will post Does Air Pollution Cause Lung Cancer?. Probably. It has long been suspected that air pollution may cause lung cancer. Studies of geographical differences in the risk of lung cancer reveal that lung cancer is more common in urban areas and less common in rural areas. Still, it has been uncertain whether air pollution is the culprit, or other factors that vary between people who live in urban versus rural areas.

When there is a question, it can be helpful to look at the science behind the theory. Studies have shown that exposure to air pollution can cause "oxidative stress," that is, damage to the cells of the body caused by oxidation. This in turn can lead to the development of cancer.

Studies in the United States, Europe, and Asia have suggested that air pollution from traffic and the combustion of coal, diesel fuel, and wood, has a modest association with lung cancer risk. In a 2009 U.S. study, it was estimated that 5% of male lung cancers and 3% of lung cancers in women between 1970 and 1994 were related to air pollution. One study looking at urban air pollution in Europe suggests that the risk may be higher, with up to 10.7% of lung cancer cases considered related to exposure to air pollution.

Environmental Causes of Lung Cancer

noreply@blogger.com (Anonymous) — Sun, 13 Jul 2014 12:57:00 +0000

Bateeilee blog admin will share Environmental Causes of Lung Cancer. Many environmental exposures - not just cigarette smoke - can raise the risk of developing lung cancer. And, like smoking, many of these are avoidable if we are aware of them. You can reduce your risk by doing things as simple as testing your home for radon, and using an appropriate mask when working with certain chemicals. Some of the most common environmental causes of lung cancer include:

Radon

Exposure to radon in the home is the second-leading cause of lung cancer and the leading cause in nonsmokers. It's estimated that around 21,000 people develop lung cancer from radon each year -- a cancer with a 5-year survival rate of only 15%. To put this in perspective, around 39,000 women die from breast cancer each year.

Radon is a radioactive gas that is produced by the natural decay of uranium in the soil. It can enter homes through cracks in the foundation, around sump pumps and drains and through gaps around pipes and wires. Having been found in homes in all 50 states, the only way to know if you are safe is to test your home for radon. Simple do-it-yourself test kits are available at most hardware stores.

Radon Mitigation

Asbestos

Exposure to asbestos is ordinarily considered an occupational exposure, but working with asbestos insulation in older homes (those built prior to 1970) can result in exposure too. Asbestos is responsible for roughly 84% of cases of mesothelioma, a cancer involving the lining of the lungs, and is responsible for other forms of lung cancer as well. Left alone, asbestos poses little danger, but exposure can result if it is disturbed. If you choose to remodel a home that may contain asbestos insulation, hire a certified contractor.

Air Pollution

Air pollution has been looked at as a possible risk factor for lung cancer, because there is a significant difference between the incidence of lung cancer in urban and rural areas, with lung cancer being more prevalent in urban areas. It is uncertain to what degree air pollution contributes to lung cancer in the United States, but according to the largest study to date, more than 10% of lung cancers in Europe may be secondary to air pollution.

More About Air Pollution and Lung Cancer

Industrial Chemicals

As with asbestos, most exposures to cancer-causing chemicals occur in the workplace. Certain products used in the home, such as some wood strippers, contain chemicals that are associated with an increased risk of lung cancer. It's important to read labels on any of these products and take appropriate precautions as directed on the packaging.

Radiation Exposure

Exposure to medical radiation to the chest for other cancers, for example Hodgkin’s lymphoma or breast cancer, can increase the risk of lung cancer, although the benefits of treatment usually far outweigh this risk. In Japan, exposure to atomic bomb radiation was associated with an elevated risk of developing lung cancer.

Secondhand Smoke

Secondhand smoke increases the risk of lung cancer in an exposed nonsmoker two- to- three-fold times. It is currently felt to be responsible for 1.6% of lung cancers in the United States (roughly 3,000 cases per year.)

More About Secondhand Smoke and Lung Cancer

Wood Smoke

Exposure to wood smoke may increase the risk of lung cancer. Converting from wood-burning stoves and fireplaces to other options, such as gas fireplaces, is one way to reduce this risk.

Lung Cancer in Women

noreply@blogger.com (Anonymous) — Sat, 12 Jul 2014 14:36:00 +0000

Bateeilee Blog admin will post Lung Cancer in Women. Lung cancer in women differs from lung cancer in men in many ways. Yet, despite obvious differences in our appearance, we tend to lump men and women together when talking about lung cancer. This is unfortunate, since the causes, response to various treatments, survival rate, and even symptoms to watch for differ. What are some facts about lung cancer in women?

Statistics About Lung Cancer in Women

Lung cancer is the leading cause of cancer deaths in women, killing more women each year than breast cancer, uterine cancer, and ovarian cancer combined. While smoking is the number one cause, 20% of these women have never touched a cigarette.

Once considered a “man’s disease,” lung cancer is no longer discriminatory. In 2005, the last year for which we have statistics, 82,271 women (vs 107,416 men) were diagnosed with lung cancer, and 69,078 (vs 90,139 men) died.

While lung cancer diagnoses decreased each year from 1991-2005 for men, the incidence increased 0.5% each year for women. The reason for this is not completely clear.
Lung cancer in women occurs at a slightly younger age, and almost half of lung cancers in people under 50 occur in women.

Causes

Even though smoking is the number one cause of lung cancer in women, a higher percentage of women who develop lung cancer are life-long non-smokers. Some of the causes may include exposure to radon in our homes, secondhand smoke, other environmental and occupational exposures, or a genetic predisposition. Recent studies suggest infection with the human papilloma virus (HPV) may also play a role.

Smoking Status

Some, but not all, studies suggest that women may be more susceptible to the carcinogens in cigarettes, and women tend to develop lung cancer after fewer years of smoking.

Lung Cancer Types

Whereas men are more likely to develop squamous cell lung cancer, another form of non-small cell lung cancer, adenocarcinoma is the most common type of lung cancer found in women. BAC (Bronchioalveolar carcinoma) is a rare form of lung cancer that is more common in women. For unknown reasons, the incidence of BAC appears to be increasing worldwide, especially among younger, non-smoking women.

Symptoms

We hear about the symptoms of a heart attack being different in women from in men. The same could hold true for lung cancer. Squamous cell lung cancer (the type more common in men) grows near the airways, and often presents with the “classic symptoms” of lung cancer, such as a cough and coughing up blood. Adenocarcinomas (the type of lung cancer that is more common in women), often develops in the outer regions of the lungs. These tumors can grow quite large or spread before they cause any symptoms. Symptoms of fatigue, the gradual onset of shortness of breath, or chest and back pain from the spread of lung cancer to bone, may be the first sign that something is wrong.

More About Symptoms of Lung Cancer in Women

Lung Cancer in Women – The Role of Estrogen

It is likely that estrogen plays a role in the development and progression of lung cancer and research is being done to define this further. Women who have their ovaries removed surgically before menopause may be at higher risk of developing lung cancer. Recent research suggests that treatment with estrogen and progesterone (hormone replacement therapy) after menopause may increase the risk of dying from lung cancer. In contrast, both the use of birth control pills and hormone replacement therapy (excepting those who use hormones after surgical menopause) are associated with a lower risk of developing lung cancer. This contrast between dying from, and development of, lung cancer, suggests that estrogen plays more than one role in lung cancer.

Treatment

Women historically respond to a few chemotherapy medications used for lung cancer better than men. One of the new targeted therapies, erlotinib (Tarceva), also appears to be more effective for women. Women who are able to be treated with surgery for lung cancer also tend to fair better. In one study, the median survival after surgery for lung cancer was twice as long for women as for men. On the other hand, even though the National Cancer Institute recommends that all patients with stage 3 lung cancer be considered candidates for clinical trials, women are less likely to be involved in clinical trials than are men.

Survival

The survival rate for lung cancer in women is higher than for men at all stages of the disease. Sadly, the overall 5-year survival rate is only 16% (vs 12% for men).

Awareness and Funding

Even though many more women die from lung cancer than breast cancer, much more funding is devoted to breast cancer research than lung cancer research. According to the Lung Cancer Alliance, federal research funding in 2007 from the National Cancer Institute, Department of Defense, and Centers for Disease Control amounted to $23,754 per breast cancer death, and only $1,414 per lung cancer death. Due to a lower survival rate, and the symptoms of lung cancer (many survivors cannot walk and run for the cure), as well as the stigma, private fundraising also lags significantly behind that of breast cancer.

How Can Women Reduce Their Risk of Lung Cancer?

Thankfully, even though lung cancer is the leading cause of cancer deaths in women, it is a largely preventable disease:

If you smoke, quit
Avoid secondhand smoke
Test your home for radon
Eat a healthy diet.
Exercise.

Lung Cancer in Men

Bateeilee Blog admin will post Lung Cancer in Men. Just as men and women differ in ways from body build to clothes preference, lung cancer in men differs from lung cancer in women in many ways. We have known for a long time that the survival rate for men with lung cancer is lower than it is for women. On the other hand, the good news is the death rate for lung cancer in men (unlike women) has been dropping in recent years.

Statistics

Lung cancer is the leading cause of cancer deaths in men, both in the United States and worldwide. In 2006, the last year for which we have statistics available, there were 106,374 men diagnosed with lung cancer in the U.S., and 89,243 men died from the disease.
Unlike lung cancer in women which now appears to be stabilizing after increasing for many years, the rate of lung cancer in men has been decreasing. From 1994 to 2006, death rates from men with lung cancer dropped by 2% per year.

The average age at which lung cancer is diagnosed in men is somewhat older than that of women at age 71. The lifetime risk of a man developing lung cancer (smokers and non-smokers combined) is 1 in 13.

Lung Cancer Statistics

Symptoms and Signs of Lung Cancer in Men

Just as men tend to have more “typical” symptoms of a heart attack, they are also more likely to have symptoms and signs associated with lung cancer. The types of lung cancer that are more common in men often grow near the central airways of the lungs. Because of this a persistent cough, coughing up blood, wheezing, and repeated infections due to airway obstruction (such as pneumonia) may be more common.
A unique set of symptoms called paraneoplastic syndrome is also more common in the types of lung cancer found in men. These symptoms may include weakness in the upper limbs, muscle cramps, and loss of coordination among others.

Causes

Occupational exposures account for a significant percentage of lung cancers in men, and in some studies is considered to be responsible for 13 to 29% of cases. Common occupations linked with an increased risk of developing lung cancer include metal workers, painters, cleaners, bakers, plumbers and pipe fitters, welders, freight handlers, and construction workers.

While smoking is considered the cause of roughly 80% of lung cancers in women, close to 90% of lung cancers in men are related to smoking. It is important to note that many men that develop lung cancer do not currently smoke. In fact, roughly half of the men currently living with lung cancer were former smokers at the time of their diagnosis.

Lung Cancer Causes
Occupational Causes of Lung Cancer

Common Types of Lung Cancer Found in Men

There are two primary types of lung cancer, non-small cell lung cancers and small cell lung cancers.
Non-small cell lung cancers are in turn broken down into three types that account for about 80% of lung cancers. Of these, squamous cell lung cancers and large cell lung cancers, cancers that grow near the central airways in the lung, are more common in men. In contrast, lung adenocarcinomas, cancers that grow near the outer regions of the lung, are more commonly found in women.
Small cell lung cancers are more commonly found in men. These cancers also tend to grow in the central areas of the lung and spread early on, often to the brain.

Types of Lung Cancer

Treatment Differences

Men and women tend to respond in a similar way to many of the traditional chemotherapy medications for lung cancer. Some of the newer targeted therapies may be more effective in women, especially in younger women who have never smoked.

Prognosis

The survival rate for lung cancer in men is lower than that for women at all stages of the disease. Sadly, the overall 5-year survival rate is only 12 % (vs 16% in women).

Support for Men With Lung Cancer

Due to the stigma of lung cancer, both men and women have sometimes felt less compassion than do people with other forms of cancer. On top of this, men may be less likely to seek out emotional support. Many excellent support groups, including online support groups are available to help men connect and support each other in their journey's with lung cancer.

Lung Cancer Support Groups

How Can Men Reduce Their Risk of Lung Cancer?

Quitting smoking is by far the most important thing anyone can do to lower their risk of developing lung cancer. That said, since the majority of people who develop lung cancer do not smoke – they are either former smokers or never smoked – it is important to look at other ways risk can be lowered as well.

If you smoke, quit
Test your home for Radon
Be aware of occupational causes and take appropriate precautions
Avoid secondhand smoke
Exercise

What is Lung Cancer?

noreply@blogger.com (Anonymous) — Sat, 12 Jul 2014 14:19:00 +0000

Bateeilee blog admin will share What is Lung Cancer?. Lung cancer arises when a series of mutations in normal lung cells cause them to become abnormal and grow out of control. These changes can take place anywhere from the bronchus (the windpipe), down to the small air sacs in the periphery of the lungs where oxygen exchange takes place.

How Common is Lung Cancer?

Once uncommon, the surge in smoking of the 20th century has contributed to a tremendous rise in the incidence of lung cancer. Lung cancer is now the leading cause of cancer death in men and second leading cause of cancer death in women worldwide. On the bright side, with widespread awareness of the risks of smoking, many hope these numbers will decrease in the future.

Causes of Lung Cancer

Tobacco use is responsible for almost 90% of lung cancer cases. That being said, those who have never smoked or quit long ago, may develop lung cancer as well. Common causes include radon exposure in the home, workplace chemicals such as asbestos, and environmental pollutants including secondhand smoke.

Symptoms of Lung Cancer

Lung cancer most commonly presents with a cough that does not go away over time. Sometimes it shows up with vague symptoms, such as fatigue, and about 25% of the time, there are no symptoms at all. Since lung cancer is common, anyone, especially those who smoke, should seek prompt medical attention for any symptom that is new or unexplained. The most common symptoms include:

A chronic cough
Coughing up blood (hemoptysis)
Difficulty breathing
Wheezing
Hoarseness
Pain in the chest, back, shoulder, or arm

Lung Cancer Diagnosis

Lung cancer is often suspected initially from a chest x-ray done to evaluate a cough or chest pain. Further studies are performed to determine if the abnormality is benign (non-cancerous), or malignant (cancerous.) If these show cancer, further tests may be performed to see whether the cancer has spread (metastasized) to other areas in the body.

Screening for Lung Cancer

Types of Lung Cancer

There are two major types of lung cancer. Non small-cell lung cancer accounts for roughly 80% of cases. Small cell lung cancer, which is usually causes by smoking, comprises 15% of lung cancers and tends to spread quickly. Rare forms of lung cancer include carcinoid tumors and mesothelioma.

Lung Cancer Types
Non-Small Cell Lung Cancer
Small Cell Lung Cancer

Stages of Lung Cancer

Non small cell cancer is divided into stages from 1 to 4 depending on how far the cancer has spread. Stage 1 is localized. Stage 2 has spread locally, often to a lymph node. Stage 3A and Stage 3B involves further spread locally but beyond the lung. Stage 4 indicates spread to another region of the body. Small cell cancer is separated into two stages based on whether the cancer is limited or extensive.

How is Lung Cancer Treated?

Depending upon the stage and type of lung cancer diagnosed, treatment may include surgery, chemotherapy, and/or radiation therapy. New treatments, often with fewer side effects, are becoming available that target lung cancer.

Chemotherapy

What is My Prognosis?

Caught early when it can be treated with surgery, lung cancer can be very curable. Sadly, the majority of people with lung cancer are diagnosed after the cancer has spread too far to do surgery. Even in this case (inoperable lung cancer,) treatment can increase length of survival, and sometimes result in long-term cancer free remission. Since people vary widely in their general health at the time of diagnosis, it can be discouraging and misleading to look at statistics. Your health care provider is a better source for looking at your individual situation.

Know Your Type of Arthritis

noreply@blogger.com (Anonymous) — Fri, 11 Jul 2014 15:09:00 +0000

Bateeilee Blog admin will post Know Your Type of Arthritis. It's not uncommon to hear people say "I have arthritis." Generally speaking, they are correct, but more accurately, they have a specific type of arthritis. There are over 100 types of arthritis. Most of the 100 types are rare diseases. You can count on two hands the types you have probably heard of at all, and on two fingers the ones most referred to and considered most common: (osteoarthritis and rheumatoid arthritis).

Symptoms That Suggest Arthritis

People who are experiencing early, vague symptoms related to joint pain, joint stiffness, joint swelling, or limited range of motion may suspect arthritis. But arthritis symptoms, especially early arthritis symptoms, can overlap with other conditions.

It is important to have a doctor assess your symptoms and accurately diagnose your condition. Before x-rays are taken or blood tests are ordered, you may not know if you are dealing with an acute joint injury or a chronic disease. To determine the cause of your symptoms, your doctor must take your medical history, perform a physical examination, and order diagnostic tests. While the pattern of symptoms will give clues, symptoms alone do not formulate a diagnosis.

The Importance of Diagnosing the Right Condition

When it comes to initial symptoms, people tend to self-treat before consulting a doctor. Perhaps no harm comes from taking a stab at self-treatment, but there's likely no significant benefit either. Typically, people try common over-the-counter treatments, hoping something will make a difference. Many people who choose to self-treat find that symptoms persist. They realize they are treading water, if not getting worse, without doctor's input. Others continue to self-treat or just live with their symptoms, risking the consequences that come from delaying appropriate treatment.

The Centers for Disease Control and Prevention estimate that while more than 10 million Americans have chronic joint symptoms, most have not been evaluated or treated by a doctor. Of the 2.2 million people believed to have rheumatoid arthritis in the U.S., more than 700,000 have not been diagnosed or treated. Of the 1.5 million who have been diagnosed with rheumatoid arthritis, more than 800,000 are under the care of a primary care physician, not a rheumatologist (a specialist in arthritis and rheumatic diseases).

Few joints may be involved at the initial consultation with a doctor. There may not be much revealed when results come back from blood tests or x-rays. But your doctor will order more extensive tests until a diagnosis can be made.

Early, Disease-Modifying Treatment Brings Best Results

Some types of arthritis are inflammatory, while others are non-inflammatory. Rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis are examples of inflammatory arthritis. Osteoarthritis is a type of arthritis that has been classified as non-inflammatory (although newer research has suggested there may be an inflammatory process involved with osteoarthritis).

A class of drugs known as disease-modifying anti-rheumatic drugs (DMARDs) are effective for many patients with inflammatory types of arthritis. When DMARDs are indicated, early treatment is essential. A meta-analysis of 14 clinical trials involving more than 1,400 patients established that early DMARD use was important, and that held true regardless of the type of DMARD prescribed. Patients who received DMARD therapy early had a better outcome than those who delayed treatment -- and the best chance for preventing joint damage.

Researchers are working on the development of disease-modifying osteoarthritis drugs (DMOADs), too. At this point, there are no osteoarthritis drugs that can slow progression of the disease. Drugs such as nonsteroidal anti-inflammatory drugs (NSAIDs) and pain medications mostly impact symptoms, not disease progression. When only one or few joints are involved, injections of (cortisone or hyalgan may be used to bring inflammation under control.

The Bottom Line

It's important to know your type of arthritis so that you can receive the proper treatment. Early, aggressive treatment is essential for bringing arthritis under control and slowing progression of the disease. Your doctor will guide you to the best treatment option with the goal of controlling symptoms and preventing permanent joint damage. Whether you start with NSAIDs (nonsteroidal anti-inflammatory drugs), corticosteroids, DMARDs, biologics, or a combination -- early treatment is the way to go.

What Is Arthritis?

noreply@blogger.com (Anonymous) — Fri, 11 Jul 2014 14:34:00 +0000

Bateeilee blog admin will share What Is Arthritis?. Many people think arthritis is a single disease, but it's not. Arthritis literally means "joint inflammation" and refers to a group of more than 100 rheumatic diseases and related conditions that are associated with joint pain, joint stiffness and swelling.

Certain arthritic conditions can affect parts of the body other than the joints. For example, tendons, muscles, and skin can become inflamed and painful. Some rheumatic conditions can affect internal organs and result in debilitating or even life-threatening complications.

The two most common types of arthritis are osteoarthritis and rheumatoid arthritis. While they are both classified as arthritis, osteoarthritis and rheumatoid arthritis are very different and must be distinguished.
Many people believe arthritis is a disease that only affects old people. In fact, arthritis can affect anyone at any age, including children. The incidence of arthritis increases with age, but nearly 3 out of 5 people with arthritis are under age 65.

If left undiagnosed and untreated, many types of arthritis can cause irreversible damage to the joints, bones, organs, and skin. It is essential to be diagnosed early in the course of the disease and treated appropriately. Knowing your type of arthritis is essential.

Osteoarthritis

Osteoarthritis, also known as degenerative joint disease, results from wear and tear on the joint. Cartilage damage develops which can lead to decreased joint function. The first signs of osteoarthritis are:

joint pain
joint tenderness
joint swelling
decreased range of motion

Usually, osteoarthritis onset is subtle and gradual, involving one or only a few joints. The joints most often affected are the:

knees
hips
hands
spine

The risk of developing osteoarthritis increases with age. Other risk factors include: joint injury, obesity, and repetitive use of the joint.

Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease which occurs when the body's own immune system mistakenly attacks the synovium (cell lining inside the joint). Rheumatoid arthritis is an inflammatory type of arthritis, chronic and potentially disabling. The first signs of the disease are:

joint pain
joint stiffness
joint swelling
loss of joint function

While the cause remains elusive, doctors suspect that genetic factors play some role in predisposition to the disease. But there is more than genetic predisposition. It is thought that there are also environmental triggers for rheumatoid arthritis.

Juvenile Arthritis

Juvenile arthritis is a general term for all types of arthritis that occur in children, 16 years old or younger. Juvenile rheumatoid arthritis is the most prevalent type of arthritis in children. There are three major types of JRA:

Polyarticular (affecting many joints)
Pauciarticular (pertaining to only a few joints)
Systemic (affecting the entire body)

Signs and symptoms of juvenile rheumatoid arthritis vary from child to child. No single test can conclusively establish a diagnosis. Juvenile arthritis must be present consistently for six or more consecutive weeks before a correct diagnosis can be made.

Psoriatic Arthritis

Psoriatic arthritis is similar to rheumatoid arthritis. About 5% of people with psoriasis (a chronic skin disease) also develop psoriatic arthritis. In psoriatic arthritis, there is inflammation of the joints and sometimes the spine.

Fibromyalgia

Fibromyalgia syndrome is a painful condition characterized by:

muscle pain
chronic fatigue
poor sleep

Fibromyalgia is characterized by pain in the muscles, ligaments and tendons. Fibromyalgia is a type of soft tissue or muscular rheumatism and does not cause joint deformities.

Gout

Gout is a painful type of arthritis that causes sudden, severe attacks of pain, tenderness, redness, warmth, and swelling in the joints, especially the big toe. The pain and swelling associated with gout are caused by uric acid crystals that precipitate out of the blood and are deposited in the joint.

Pseudogout / CPPD

Pseudogout, which is also known as Calcium Pyrophosphate Dihydrate Deposition Disease (CPPD), is caused by deposits of calcium phosphate crystals (not uric acid) in the joints. CPPD is often mistaken for gouty arthritis. Since CPPD is a different disease than gout, treatment is not the same.
